We examine the short-term and long-term impact of bilateral agreements on migrant workers’ vulnerability during their employment in Israel. To do so, we developed the Vulnerability Index of Migrant Workers based on five dimensions: poor working conditions, poor living conditions, poor safety conditions, low wages, and dependence on migration costs. We focus on migrant workers arriving in Israel from two different countries, employed in two different sectors of the economy. Data was gathered through a survey conducted among workers arriving (...) from both countries before and after the implementation of the bilateral agreements. The study revealed that after the implementation of bilateral agreements, the working, living and safety conditions of migrant workers remained poor or even worsened. For Thai workers, there was a slight improvement in the working and living conditions in the short term after the bilateral agreement, but they worsened in the long run. The total Index of Vulnerability of both groups showed improvement due to the dramatic decrease in dependence on migration costs, despite the deterioration in some working and living conditions and the reduction in migrant workers’ relative wages.

Subject and purpose: Using annual data for the periods 2009–2019, this paper examines trade flows between China and the Visegrad Group countries. The aim of this article is to assess real changes taking place in international trade in the Visegrad Group countries over the last eleven years. The starting point for the analysis was 2009 – the time after the 2008 economic crisis, and it was compared especially to 2018 – a year marked by a significant improvement in the economy. (...) The purpose is to discuss concerns related to the differences in bilateral trade between China and Poland, Czech Republic, Hungary, and Slovak Republic. The main aim of this research is to distinguish the characteristics of bilateral trade by products between V4 and China in years 2009–2019. The purpose of this article is also to systematize and discuss points of view, rationalizing further empirical research. Two research hypotheses, resulting from the research purpose, were formulated: H1: in the V4 countries import exceeds export, and this trend seems to be growing, H2: Chinese goods imported to the V4 are much more sophisticated than those exported. Design/methodology/approach: To assess the initial and current situation on international trade between the V4 and China, the author uses variables obtained from WTO and OEC resources, diagnosing the situation in Poland, Czech Republic, Hungary, and Slovak Republic. The collected empirical data were processed using theoretical methods such as analysis, synthesis, and comparison to formulate conclusions using deductive and inductive inference methods. Practical Implications: The results can be used in scientific and expert work on diagnostic and forecast trends in bilateral trade by products between the V4 and China. Originality/value: It concerns the indication of the importance of the V4 trade with China compared to the share of the V4 countries in world trade. It was also possible to identify the top export and import products of the V4. The findings also confirm the significant change in China’s trading structure. (shrink)

The United States (U.S.) and Jordan launched negotiations for a free trade agreement in 2000.The US-JO FTA includes a preamble, nineteen articles, three annexes, joint statements, memorandums of understanding, and side letters. In addition to the interesting articles on labor and environment, the US-JO FTA provides the opportunity for Jordanian nationals to come to the U.S. to make investments and participate in trade. Under certain conditions, Jordanian nationals can enter the U.S. to render professional services. The purpose of this article (...) is to examine in detail article 8 of the US-JO FTA which relates to entry of nationals of one party into the territory of the other. The article starts by providing a brief background of the negotiation and conclusion of the US-JO FTA. Then, the article analyzes in detail the specific provision related to temporary entry of nationals. The article draws a comparison between US-JO FTA with the North American Free Trade Agreement (NAFTA) and the more recent trade agreements between the U.S., Oman, Bahrain, and Morocco. Finally, the article observes that although the US-JO FTA, like all US FTAs, is designed to permit temporary entry, without intent to establish permanent residence, of persons, the U.S. should have provided Jordan with special and differential treatment for entry of its nationals. Taking into account the special circumstances of Jordan as a developing country with low-income status, high unemployment rate, and lack of resources, movement of business visitors, investors, intra-company transferees, and professionals should have been dealt with leniency so that the FTA could generate effective and real market access.

The aim of this paper is to provide a philosophical interpretation of bilateralism in terms of probabilism. In particular, to interpret the main concepts of bilateralism –acceptance, rejection and incoherence– in terms of the probabilistic notions of degree of belief and coherence. According to bilateralism, the meaning of logical connectives is determined by the acceptance and rejection conditions of the sentences in which they are involved, where acceptance and rejection cannot be reduced to one another. I will focus on a (...) variant of bilateralism that understands logical consequence as the statement that it is incoherent to accept all the premises of a valid argument while rejecting all its conclusions. On the other hand, probabilism states that it is possible to interpret our degrees of belief in terms of probabilities. The aim of this work is then to interpret the concept of incoherence in terms of probability functions and determine when it is coherent to accept or to reject a proposition according to some threshold defined in terms of degrees of belief. To achieve this goal, we need both an interpretation of the concept of incoherence coined by the bilateralists as well as an interpretation of acceptance and rejection. I will show that a good interpretation of coherence in probabilistic terms can already be found in the literature. Then, I will give an interpretation of acceptance and rejection in terms of degrees of belief. In particular, I will show that it is possible to interpret these concepts in accordance with Locke’s thesis, the thesis that states that there is some threshold r such that if you believe some sentence in degree equal or higher than r you should accept it, without falling into epistemic paradoxes.

This Article discusses BLAs as tools of global labor migration governance, with a specific focus on gender. Drawing on our global database of 582 bilateral labor migration agreements, we investigate the extent to which these governing instruments connect and align with relevant international normative frameworks, in particular the extent to which they represent gains, gaps or gaffs in terms of gender equality and the human and labor rights protection of women migrants. In the context of the Global Compact for (...) Safe, Orderly and Regular Migration, which stresses a gender-responsive approach to migration governance as one of its guiding principles, we ask: Do the BLAs which are increasingly being used as instruments to govern labor migration contribute toward sustainable gender equality, decent work and reduced inequalities for women and gender-diverse migrants?

This Article offers an integrated analysis of the combined effect of the presence of migration bans and the absence of BLAs in domestic work in the emigration regime of Nepal. It identifies, acknowledges, critiques, and contributes to the critical literature highlighting entrapment processes in labor relations and immigration regimes by demonstrating the presence of such in the emigration regime. Drawing on the empirical findings of a participatory action research project conducted in Nepal, the Article demonstrates how restrictive emigration policies and (...) practices entail entrapment processes constitutive of the existing historical, cultural, gendered, racialized, and classed constraints impacting the lives of Nepalese citizens. The Article contributes to the critical literature that seeks to advance migrants’ rights, arguing that experiencing, encountering and escaping entrapment processes in the emigration regime impacts their agency when navigating immigration regimes and labor relations. This contribution advances the existing efforts to establish oft-ignored emigration regimes as important epistemological sites of research, theorization, and intervention. (shrink)

It’s commonly thought that, in conversation, speakers accept and reject propositions that have been asserted by others. Do speakers accept and reject questions as well? Intuitively, it seems that they do. But what does it mean to accept or reject a question? What is the relationship between these acts and those of asking and answering questions? Are there clear and distinct classes of reasons that speakers have for acceptance and rejection of questions? This chapter seeks to address these issues. Beyond (...) their intrinsic interest to those working on the nature of questions, solutions to these problems may aid the extension of inferentialist approaches to logic and language. Inferentialists who think that inferences should be conceived in terms of the norms we are subject to in virtue of both the sentences we accept or assert as well as those we reject or deny are known as bilateralists. A coherent account of accepting and rejecting questions raises the prospects for a bilateralism that interprets question-involving or erotetic inferences according to these additional primitives. While a full-blown bilateralism for erotetic inferences and ultimately for question-forming operators themselves far exceeds this chapter’s scope, the work presented here does sketch the first steps in that direction.

PurposeThe purported benefits and risks of immediately sequential bilateral cataract surgery have been well described, yet the procedure remains controversial among UK ophthalmologists. As many of the controversies of ISBCS are underpinned by ethical dilemmas, the aim of this work was to explore the ethical perspectives of ISBCS from a variety of stakeholder viewpoints.MethodA semi-structured independent stakeholder meeting was convened at the Royal College of Ophthalmologists London headquarters in June 2018. In total, 29 stakeholders attended the meeting. The professional (...) characteristics of stakeholders included but were not limited to: ophthalmologists, patients, religious leaders, ethicists, lawyers and commissioners. Thematic qualitative analysis using methodology proposed by Braun and Clarke was conducted on the resultant transcript of the discussion.ResultsThemes identified include: beneficence and non-maleficence ; autonomy ; distributive justice.ConclusionThis analysis provides a reference point for the ethical factors surrounding ISBCS. The stakeholders concluded that this approach was an ethical undertaking provided patient autonomy was appropriately attained. This requires a patient’s interpretation of the risk-benefit balance, which must include an understanding of the low but unquantifiable risk of severe complications. A surgeon must aim to minimise risks through the adaption of accepted surgical protocols and by performing appropriate patient selection. Currently, cost savings to healthcare that may occur following the implementation of ISBCS should be considered a secondary benefit of the protocol. (shrink)

ASEAN agricultural workers represent one of the most vulnerable groups of workers regardless of citizenship. While bilateral agreements focus on general migration governance mechanisms, the specifics of agricultural workers’ rights and protections fall outside their scope. Due to the seasonal nature of cross-border agriculture, these are flexible precarious workers readily available to employers in the borderlands that often do not invest in worker health and social security. The Article reveals how foreign migrant agricultural workers with and without work permits (...) continue to fall between the gaps of national labor protection laws, due to both legal structural exclusions as well as the particular vulnerabilities of being noncitizen workers in remote, unsafe workplaces. This Article documents some of the developments during 20172019 in migrant employment in export cash crops. The next challenge for the future is developing mechanisms for bilateralism to lower migration costs, with a commitment to genuinely safe migration, as well as the establishment of long-term equitable working conditions for all migrant workers. The major findings demonstrate how the two main reasons for the discrepancies between the BLA and labor protections have to do with the noninterventionist approach of ASEAN and a series of technical exclusions in Thailand’s labor law and regulation.

Background: Eye movement desensitization and reprocessing [EMDR] is an innovative, evidence-based and effective psychotherapy for post-traumatic stress disorder [PTSD]. As with other psychotherapies, the effectiveness of EMDR contrasts with a limited knowledge of its underlying mechanism of action. In its relatively short life as a therapeutic option, EMDR has not been without controversy, in particular regarding the role of the bilateral stimulation as an active component of the therapy. The high prevalence of EMDR in clinical practice and the dramatic (...) increase in EMDR research in recent years, with more than 26 randomized controlled trials published to date, highlight the need for a better understanding of its mechanism of action. Methods: We conducted a thorough systematic search of studies published until October 2017, using PubMed, ScienceDirect, Web of Knowledge and Scopus databases that examined the mechanism of action of EMDR or provided conclusions within the framework of current theoretical models of EMDR functioning. Results: Seventy-five studies were selected for review and classified into three overarching models; (i) psychological models (ii) psychophysiological models and (iii) neurobiological models. The evidence available from each study was analysed and discussed. Results demonstrated a reasonable empirical support for the working memory hypothesis and for the physiological changes associated with successful EMDR therapy. Recently, more sophisticated structural and functional neuroimaging studies using high resolution structural and temporal techniques are starting to provide preliminary evidence into the neuronal correlates before, during and after EMDR therapy. Discussion: Despite the increasing number of studies that published in recent years, the research into the mechanisms underlying EDMR therapy are still in its infancy. Studies in well-defined clinical and non-clinical populations, larger sample sizes and tighter methodological control are further needed in order to establish firm conclusions. (shrink)

In 1891 Cambridge biologist William Bateson (1861–1926) announced his idea that the symmetrical segmentation in living organisms resulted from energy peaks of some vibratory force acting on tissues during morphogenesis. He also demonstrated topographically how folding a radially symmetric organism could produce another with bilateral symmetry. Bateson attended many lectures at the Cambridge Philosophical Society and viewed mechanical models prepared by eminent physicists that illustrated how vibrations affected materials. In his subsequent research, Bateson utilized analogies and metaphors based upon (...) his observations of nature to build a thought model on the effects of vibrations on living tissue, because he realized that the chemistry and biology of his day lacked technologies to perform actual experiments on the subject. He concluded the production of organic segmentation was both a chemical and mechanical phenomenon. By the time of his death Bateson had incorporated new ideas about embryonic organizer regions to suggest a center from which a rhythmic force emanated and then produced the observed repetitive segmentation as a common feature in living organisms.

From the late seventeenth century on the idea of culture underwent a gradual transformation. Originally this concept referred essentially to the “refined” way of life of the ruling social elite. Popular culture, on the other hand, refers to the usually collective practices of groups of rural and urban workers taking the form of performance. They were not only excluded from refined culture, but it was regarded as completely unsuitable for them, potentially creating dangerous social aspirations. It is with the great (...) social transformation from feudal to bourgeois society that the idea of refined culture was replaced by that of “high culture” encompassing both the arts and the sciences: works claiming universal human significance. This “high culture” for a considerable time coexisted with the remnants of popular culture. It has been only due to the great technical advances that its true opposite, “mass culture” emerged, at the turn to twentieth century, claiming an empirical universality: being understandable and truly interesting to everyone. In economic respect, there is a competitive relation between high and mass culture. However, it is argued that there can be no cultural competition between them. For they posit differing and potentially co-existing receptive attitudes. The characterisation of this difference and the discussion of the seeming exceptions to the so-articulated conceptual scheme occupies the concluding part of this essay. (shrink)

Working memory is the system responsible for maintaining and manipulating information, in the face of ongoing distraction. In turn, WM span is perceived to be an individual-differences construct reflecting the limited capacity of this system. Recently, however, there has been some evidence to suggest that WM capacity can increase through training, raising the possibility that training can functionally alter the neural structures supporting WM. To address the hypothesis that the neural substrates underlying WM are targeted by training, we conducted a (...) meta-analysis of functional magnetic resonance imaging studies of WM training using Activation Likelihood Estimation. Our results demonstrate that WM training is associated exclusively with decreases in blood oxygenation level-dependent responses in clusters within the fronto-parietal system that underlie WM, including the bilateral inferior parietal lobule, middle and superior frontal gyri, and medial frontal gyrus bordering on the cingulate gyrus. We discuss the various psychological and physiological mechanisms that could be responsible for the observed reductions in the BOLD signal in relation to WM training, and consider their implications for the construct of WM span as a limited resource.

The paper presents an analysis of the ethical, political and economic aspects of human work within two Polish historical periods – the years of the People’s Republic of Poland and after 1989. The starting point for the analysis was the assumption that every time period, each age, leaves a mark on man’s work. Analysis of the People's Republic of Poland period gives an opportunity to consider human work understood as a duty and right of every human guaranteed by the Constitution (...) of 1952. Questioning the principles ruling the labour market by the ideologists of the People’s Republic of Poland and, as a consequence, the politicization of labour, resulted in the collapse of the work ethic. Work, as it was at that time a commonly available good, lost its value, regarded as the source of life satisfaction, and thus became ridiculed. After 1989, in relation to the de-politicization of the Polish labour market, the employee became active in searching for a job. The phenomenon of unemployment resulted in competition on the labour market and the employer was thus given the opportunity to freely select a group of employees. As a result, the employer became a distributor of a ‘rare commodity.’ That, in turn, led to the situation where the approach of employers towards employees turned into the employer's diktat. It is the employer who determines the conditions of employment, standards of work and place of work. A lack of alternative that many employees face often makes them accept the dictated conditions of work. What is more, in Poland we deal with the insufficiently developed participation of employees in managing the enterprises, which is an effect of breaking off the bilateral dependency of employee and employer.

The aggressive foreign policy of the Soviet Union and insufficient dynamic development of Soviet culture of the late 70's of XX century led to a slowdown in the British-Soviet cultural relations, including the prohibition of exchange visits between Ministers of Culture of both countries and bilateral tours of theatre, ballet and opera groups. In order to otrengthen cultural relations between the UK and the Soviet Union, the leadership of both countries established centers of cultural developments like the British Association (...) "Great Britain - USSR" and the Soviet Society "USSR - United Kingdom ". Top priority areas of bilateral relations between the leadership of the United Kingdom and the Soviet Union were literary industry which included publishing scientific literature, expansion of book exchange between Soviet and British libraries, exhibitions of works of literature, such as the exhibition of the works of British authors, published on the territory of the Soviet Union in 1984; theatrical sphere, which included exchange visits of the UK and the USSR theater personalities to study the trends of Performing Arts and review of countries' repertoire; contacts in the field of historical sciences by creating among States bilateral commission of historians of the USSR and the UK; research work done by Soviet specialists in the territorial waters of the United Kingdom with the permission of the British government; cooperation in the field of cinema presented directors and actors exchange visits of both countries carrying out the Soviet television Week in 1984 in the National theater of Great Britain; and constructive cooperation in the field of music, which demonstrated the International Music Festival in May 1981 in Moscow and performances of the Moscow Philharmonic, "Music of Russian rites and festivals" and "Tradition of ancient Russian music" in the early 1980's in UK. British-soviet system of contacts in the sphere of culture was a tool for establishing successful diplomatic relations between Great Britain and the Soviet Union. (shrink)

Our current work examined the interface between thinking style and emotional experience at both the behavioral and neuropsychological levels. Thirty-nine Chinese participants completed the triad task, and we calculated the rate of individually selected relationship pairings to overall selections to represent their holistic thinking tendencies. In addition, participants in the top one-third of the ratio score were classified into the high holistic thinking group, while those in the bottom one-third of the ratio score were classified into the low holistic thinking (...) group. We used the sensitivity to punishment and sensitivity to reward questionnaire to examine how people elicit positive and negative affective behaviors. Additionally, we examined the volume of the amygdala and nucleus accumbens and their functional connectivity in the resting-state. We found that high holistic thinkers were much less sensitive to rewards than low holistic thinkers. In other words, individuals with high holistic thinking are less likely to pursue behaviors that have positive emotional outcomes. Furthermore, their bilateral nucleus accumbens and right amygdala volumes were smaller than those of low holistic thinkers. Hierarchical regression analysis showed that holistic thinking tendency can negatively predict the volume of the left nucleus accumbens and right amygdala. Finally, resting-state functional connectivity results showed increased functional connectivity FC between left nucleus accumbens and bilateral amygdala in high holistic thinkers. These findings provide emotion-related manifestations of thinking styles at the behavioral and neural levels. (shrink)

Although the work of G.F.C. Griss is commonly understood as a program of negationless mathematics, close examination of Griss’s work suggests a more fundamental feature is its executability, a requirement that mental constructions are possible only if corresponding mental activity can be actively carried out. Emphasizing executability reveals that Griss’s arguments against negation leave open several types of negation—including D. Nelson’s strong negation—as compatible with Griss’s intuitionism. Reinterpreting Griss’s program as one of executable mathematics, we iteratively develop a pair of (...) bilateral constructive logics and argue for their adequacy as accounts of the propositional basis of Griss’s work. We conclude by observing connexive features exhibited by the two bilateral logics and by investigating the difficulties connexive principles reveal for the development of executable mathematics.

Jeremy sustained bilateral complete brachial plexus injuries in an auto collision on an icy road a month before his third birthday. The accident rendered both upper extremities completely flail and insensate: he has no motor or sensory function of his shoulders, elbows, wrists, or digits. Jeremy does, however, have normal function of the lower extremities. Physical therapists have worked with the child for over a year with no noted improvement in arm function. Jeremy falls frequently, causing injury to his (...) face and head, and occasionally, his arms get twisted or caught in his crib and his fingers turn blue. Jeremy's mother, who carries the main responsibility for his daily care, believes that his insensate arms are too heavy and “get in his way,” causing the falls. She and Jeremy's father present to the orthopedic clinic at the children's hospital with the request of having both arms amputated. The primary orthopedic surgeon and the orthopedic team disagree with the parents that bilateral upper-extremity amputation offers any medical benefit, but Jeremy's mother tells the surgeon that, if he will not perform the surgery, her family will find a doctor who will. The surgeon, who feels ethically distressed by the parental insistence on this amputation in such a young child, requests an ethics consultation. (shrink)

In the past two decades, changes in the Mexican government's policies toward the 30 million Mexican migrants living in the US highlight the importance of the Mexican diaspora in both countries given its size, its economic power and its growing political participation across borders. This work examines how the Mexican government's assessment of the possibilities and consequences of implementing certain emigration policies from 1848 to 2010 has been tied to changes in the bilateral relationship, which remains a key factor (...) in Mexico's current development of strategies and policies in relation to migrants in the United States. Understanding this dynamic gives an insight into the stated and unstated objectives of Mexico's recent activism in defending migrants' rights and engaging the diaspora, the continuing linkage between Mexican migration policies and shifts in the US-Mexico relationship, and the limits and possibilities for expanding shared mechanisms for the management of migration within the NAFTA framework.

We study the Iterated Bilateral Reciprocity game in which the need for help arises randomly. Players are heterogeneous with respect to ‘neediness’ i.e. probability of needing help. We find bounds on the amount of heterogeneity which can be tolerated for cooperation (all players help when asked to help) to be sustainable in a collectivity. We introduce the notion of Generalised Reciprocity. Individuals make a costly first move to benefit another under the reasonable expectation that either the other or somebody (...) else will reciprocate. We hope that these tentative attempts at extending Axelrod’s seminal work on cooperation will inspire future efforts in the field of organisational culture and social theory more generally. (shrink)

We cast doubts on the suggestion, recently made by Graham Priest, that glut theorists may express disagreement with the assertion of A by denying A. We show that, if denial is to serve as a means to express disagreement, it must be exclusive, in the sense of being correct only if what is denied is false only. Hence, it can’t be expressed in the glut theorist’s language, essentially for the same reasons why Boolean negation can’t be expressed in such a (...) language either. We then turn to an alternative proposal, recently defended by Beall (in Analysis 73(3):438–445, 2013; Rev Symb Log, 2014), for expressing truth and falsity only, and hence disagreement. According to this, the exclusive semantic status of A, that A is either true or false only, can be conveyed by adding to one’s theory a shrieking rule of the form A & ~A |- \bot, where \bot entails triviality. We argue, however, that the proposal doesn’t work either. The upshot is that glut theorists face a dilemma: they can either express denial, or disagreement, but not both. Along the way, we offer a bilateral logic of exclusive denial for glut theorists—an extension of the logic commonly called LP. (shrink)

Fronto-parietal activity has been frequently observed in fMRI and PET studies of attention, working memory, and episodic memory retrieval. Several recent fMRI studies have also reported fronto-parietal activity during conscious visual perception. A major goal of this review was to assess the degree of anatomical overlap among activation patterns associated with these four functions. A second goal was to shed light on the possible cognitive relationship of processes that relate to common brain activity across functions. For all reviewed functions we (...) observed a consistent and overlapping pattern of brain activity. The overlap was most pronounced for the bilateral parietal cortex , and dorsolateral prefrontal cortex . The common fronto-parietal activity will be discussed in terms of processes related to integration of distributed representations in the brain. (shrink)

Kelly, Gerard The tumultuous events of the sixteenth century irrevocably changed the shape of the Western Church and thus Christianity more generally. The division that ensued affected not just the institutional life of the church, but also towns and villages, families and neighbours. For generations, people lived with the consequences of this division, often within the intimacy of their own family life. Fortunately, this has changed. The twentieth century is rightly referred to as the ecumenical century. We are able to (...) point to milestones on the way to unity, beginning with the Edinburgh Missionary Conference in 1910, and then the First World Conference on Faith and Order in 1927, and the formation of the World Council of Churches in 1948. After the conclusion of the Second Vatican Council in 1965, the Catholic Church began to participate in ecumenical gatherings. Its entry brought a new way of ecumenical dialogue, and the era of the bilateral dialogue began, alongside the existing multilateral dialogue. Today the Catholic Church at the international level has been and/or continues to be in dialogue with the Anglican Communion, the Lutheran World Federation, the World Methodist Council, the World Alliance of Reformed Churches, the Baptist World Alliance, the Disciples of Christ, Pentecostals, Evangelicals, and three families of Eastern and Oriental Orthodox Churches. In Australia the Catholic Church is currently engaged in dialogue with the Anglican Church, the Lutheran Church and the Uniting Church. The Catholic Church participates in a multilateral way through both the Joint Working Group with the World Council of Churches and as a member of the Faith and Order Commission of the World Council of Churches.

The relationship between the neurobiology of speech and music has been investigated for more than a century. There remains no widespread agreement regarding how (or to what extent) music perception utilizes the neural circuitry that is engaged in speech processing, particularly at the cortical level. Prominent models such as Patel’s Shared Syntactic Integration Resource Hypothesis (SSIRH) and Koelsch’s neurocognitive model of music perception suggest a high degree of overlap, particularly in the frontal lobe, but also perhaps more distinct representations in (...) the temporal lobe with hemispheric asymmetries. The present meta-analysis study used activation likelihood estimate analyses to identify the brain regions consistently activated for music as compared to speech across the functional neuroimaging (fMRI and PET) literature. Eighty music and 91 speech neuroimaging studies of healthy adult control subjects were analyzed. Peak activations reported in the music and speech studies were divided into four paradigm categories: passive listening, discrimination tasks, error/anomaly detection tasks and memory-related tasks. We then compared activation likelihood estimates within each category for music versus speech, and each music condition with passive listening. We found that listening to music and to speech preferentially activate distinct temporo-parietal bilateral cortical networks. We also found music and speech to have shared resources in the left pars opercularis but speech-specific resources in the left pars triangularis. The extent to which music recruited speech-activated frontal resources was modulated by task. While there are certainly limitations to meta-analysis techniques particularly regarding sensitivity, this work suggests that the extent of shared resources between speech and music may be task-dependent and highlights the need to consider how task effects may be affecting conclusions regarding the neurobiology of speech and music.

This paper makes a contribution to ongoing debates about whether and how we can empirically assess the potential, limitations, and actual impacts of public-private partnerships in developing countries. Several United Nations and bilateral aid agencies have called for the development of impact assessment methodologies that can help clarify when, how, where, and for whom partnerships work. This paper scrutinizes some of the key assumptions underlying this debate, arguing that no objective ' truth' about the effects of PPPs can be (...) discovered through the use of such methodologies. The paper then investigates what can actually be known about a PPP's effects by testing a PPP IA framework that is recommended by the Organization for Economic Cooperation and Development. This is done using a case study from Pakistan. The paper shows that IA methodology may provide an indication of how well a PPP has fared, but not why the PPP has turned out the way it has. At the same time, win-win and win-lose outcomes may exist simultaneously, even for the same stakeholder in the PPP. While the importance of ensuring proper design, monitoring, and IA of PPPs cannot be denied, their effects must be seen as an outcome of struggles between a variety of actors over the distribution of social and environmental hazards associated with broader processes of economic development and industrialization.

Some accounts of the fiduciary relationship place trust and autonomy at odds with one another, so that trusting a fiduciary to act on one’s behalf reduces one’s ability to be autonomous. In this chapter, we critique this view of the fiduciary relationship (particularly bilateral instances of this relationship) using contemporary work on autonomy and ‘relational autonomy’. Theories of relational autonomy emphasize the role that interpersonal trust and social relationships play in supporting or hampering one’s ability to act autonomously. We (...) argue that fiduciary relationships, understood through the lens of relational autonomy, can provide a means of enhancing, rather than diminishing, beneficiaries’ autonomy. (shrink)

The aim of this article is to strengthen links between cognitive brain research and formal logic. The work covers three fundamental sorts of logical inferences: reasoning in the propositional calculus, i.e. inferences with the conditional “if...then”, reasoning in the predicate calculus, i.e. inferences based on quantifiers such as “all”, “some”, “none”, and reasoning with n-place relations. Studies with brain-damaged patients and neuroimaging experiments indicate that such logical inferences are implemented in overlapping but different bilateral cortical networks, including parts of (...) the fronto-temporal cortex, the posterior parietal cortex, and the visual cortices. I argue that these findings show that we do not use a single deterministic strategy for solving logical reasoning problems. This account resolves many disputes about how humans reason logically and why we sometimes deviate from the norms of formal logic. (shrink)

To model behavioral and neural correlates of language comprehension in naturalistic environments, researchers have turned to broad‐coverage tools from natural‐language processing and machine learning. Where syntactic structure is explicitly modeled, prior work has relied predominantly on context‐free grammars (CFGs), yet such formalisms are not sufficiently expressive for human languages. Combinatory categorial grammars (CCGs) are sufficiently expressive directly compositional models of grammar with flexible constituency that affords incremental interpretation. In this work, we evaluate whether a more expressive CCG provides a better (...) model than a CFG for human neural signals collected with functional magnetic resonance imaging (fMRI) while participants listen to an audiobook story. We further test between variants of CCG that differ in how they handle optional adjuncts. These evaluations are carried out against a baseline that includes estimates of next‐word predictability from a transformer neural network language model. Such a comparison reveals unique contributions of CCG structure‐building predominantly in the left posterior temporal lobe: CCG‐derived measures offer a superior fit to neural signals compared to those derived from a CFG. These effects are spatially distinct from bilateral superior temporal effects that are unique to predictability. Neural effects for structure‐building are thus separable from predictability during naturalistic listening, and those effects are best characterized by a grammar whose expressive power is motivated on independent linguistic grounds.

Blindsight, the ability to blindly discriminate wavelength and other aspects of stimuli in a blind field, sometimes occurs in people with lesions to striate (V1) cortex. There is currently no consensus on whether qualitative color information of the sort that is normally computed by double opponent cells in striate cortex is indeed computed in blindsight but doesn’t reach awareness, perhaps owing to abnormal neuron responsiveness in striate or extra-striate cortical areas, or is not computed at all. The existence of primesight, (...) the experience of colored afterimages in blindsight, has been taken to suggest that qualitative color information is computed either in pre-striate or striate cortical areas but is not broadcast to working memory. I argue here that a recent study in which color phosphenes were induced in a blindsighter using bilateral transcranial magnetic stimulation indicates that computations necessary for conscious color vision are lost in blindsight. Owing to this loss, the neural responsiveness in extrastriate cortical areas is abnormal and hence is unable to give rise to color awareness. Blindsight is thus degraded vision in which the computations necessary for conscious color vision have been lost. (shrink)

Individuals differ greatly in their ability to learn and navigate through environments. One potential source of this variation is “directional sense” or the ability to identify, maintain, and compare allocentric headings. Allocentric headings are facing directions that are fixed to the external environment, such as cardinal directions. Measures of the ability to identify and compare allocentric headings, using photographs of familiar environments, have shown significant individual and strategy differences; however, the neural basis of these differences is unclear. Forty-five college students, (...) who were highly familiar with a campus environment and ranged in self-reported sense-of-direction, underwent fMRI scans while they completed the Relative Heading task, in which they had to indicate the direction of a series of photographs of recognizable campus buildings (i.e., “target headings”) with respect to initial “orienting headings”. Large individual differences were found in accuracy and correct decision latencies, with gender, self-reported sense-of-direction, and familiarity with campus buildings all predicting task performance. Using linear mixed models, the directional relationships between headings and the experiment location also impacted performance. Structural scans revealed that lateral orbitofrontal and superior parietal volume were related to task accuracy and decision latency, respectively. Bilateral hippocampus and right presubiculum volume were related to self-reported sense-of-direction. Meanwhile, functional results revealed clusters within the superior parietal lobule, supramarginal gyrus, superior frontal gyrus, lateral orbitofrontal cortex, and caudate among others in which the intensity of activation matched the linear magnitude of the difference between the orienting and target headings. While the retrosplenial cortex and hippocampus have previously been implicated in the coding of allocentric headings, this work revealed that comparing those headings additionally involved frontal and parietal regions. These results provide insights into the neural bases of the variation within human orientation abilities, and ultimately, human navigation. (shrink)

ObjectiveTo investigate the instant impact of hemodialysis on the cerebral morphological measurements of patients with end-stage renal disease.Materials and methodsTwenty-five patients undergoing maintenance HD and twenty-eight age-, sex-, and education-matched healthy control were included. The HD group and HC group had 3D high-resolution structural magnetic resonance imaging scans twice and once, respectively. Both groups underwent neuropsychologic tests. The morphological measurements of structural MRI were measured using CAT12 and these measures were compared among three groups. The relationship between morphological measures and (...) clinical parameters and neuropsychological tests were investigated through multiple regression analysis.ResultsCompared to the HC group, the cortical thickness before HD significantly decreased in the bilateral temporal lobe and significantly decreased in the left superior temporal gyrus after HD. The cortical thickness significantly increased in the bilateral temporal lobe, frontal lobe and occipital lobe after HD compared to before HD. The sulcus depth in the bilateral insula, frontal lobe, and parietal lobe after HD significantly increased compared to before HD. No significant differences in sulcus depth between HD and HC were detected. After HD, the cortical thickness of the right parsopercularis was positively correlated with the number connection test-A. Cortical thickness in multiple regions were positively correlated with blood flow velocity and cortical thickness in the left parahippocampal gyrus was negatively correlated with ultrafiltration volume. Patients showed better performance in the digit symbol test and line tracing test after HD compared to before HD, but there were no significant differences in the comparison of neuropsychologic tests between patients and HC.ConclusionThe instant morphological changes were captured during a single hemodialysis in HD patients. There was an association between these instant changes in the brain and clinical parameters and neuropsychologic tests. This work implied the instant impact of a single hemodialysis impact on the brain in HD patients. (shrink)

Visual imagery is a form of sensory imagination, involving subjective experiences typically described as similar to perception, but which occur in the absence of corresponding external stimuli. We used the Activation Likelihood Estimation algorithm (ALE) to identify regions consistently activated by visual imagery across 40 neuroimaging studies, the first such meta-analysis. We also employed a recently developed multi-modal parcellation of the human brain to attribute stereotactic co-ordinates to one of 180 anatomical regions, the first time this approach has been combined (...) with the ALE algorithm. We identified a total 634 foci, based on measurements from 464 participants. Our overall comparison identified activation in the superior parietal lobule, particularly in the left hemisphere, consistent with the proposed ‘top-down’ role for this brain region in imagery. Inferior premotor areas and the inferior frontal sulcus were reliably activated, a finding consistent with the prominent semantic demands made by many visual imagery tasks. We observed bilateral activation in several areas associated with the integration of eye movements and visual information, including the supplementary and cingulate eye fields (SCEFs) and the frontal eye fields (FEFs), suggesting that enactive processes are important in visual imagery. V1 was typically activated during visual imagery, even when participants have their eyes closed, consistent with influential depictive theories of visual imagery. Temporal lobe activation was restricted to area PH and regions of the fusiform gyrus, adjacent to the fusiform face complex (FFC). These results provide a secure foundation for future work to characterise in greater detail the functional contributions of specific areas to visual imagery. (shrink)

This paper makes a contribution to ongoing debates about whether and how we can empirically assess the potential, limitations, and actual impacts of public–private partnerships (PPPs) in developing countries. Several United Nations and bilateral aid agencies have called for the development of impact assessment (IA) methodologies that can help clarify when, how, where, and for whom partnerships work. This paper scrutinizes some of the key assumptions underlying this debate, arguing that no objective ‹truth’ about the effects of PPPs can (...) be discovered through the use of such methodologies. The paper then investigates what can actually be known about a PPP’s effects by testing a PPP IA framework that is recommended by the Organization for Economic Cooperation and Development. This is done using a case study from Pakistan. The paper shows that IA methodology may provide an indication of how well a PPP has fared, but not why the PPP has turned out the way it has. At the same time, win–win and win–lose outcomes may exist simultaneously, even for the same stakeholder in the PPP. While the importance of ensuring proper design, monitoring, and IA of PPPs cannot be denied, their effects must be seen as an outcome of struggles between a␣variety of actors over the distribution of social and environmental hazards associated with broader processes of economic development and industrialization.

The concept of ultimate reality has an important role in the metaphysics of religious pluralism. John B. Cobb—a process philosopher in the Whiteheadian tradition—has suggested not only two ultimates, like other process philosophers, but three ultimates: God, creativity, and the cosmos. Based on this, I argue, firstly, that Cobb’s tripartite conception of the ultimate offers greater conceptual resources for inter-religious dialog than, for example, John Hick’s conception of ultimate reality or ‘the Real’. In support of this first claim, I will (...) apply Cobb’s conception of the ultimate to Zen-Buddhism, thus exemplifying the resources of this conception. Secondly, given the conclusion that Cobb’s conception of the ultimate does indeed offer greater conceptual resources, I further explicate how panentheism, understood as the thesis of a transcendent, immanent divine being who is bilaterally related to the world, can be read in terms of Cobb’s conception of the ultimate. I thus argue that panentheism in general inherits and retains many of the conceptual resources of Cobb’s understanding of the ultimate, and can be seen as a preferable position in relation to religious pluralism. Finally, I conclude from the example of Zen-Buddhism that, although Cobb’s conception offers greater resources for engaging in a dialog from a metaphysical point of view, work has to be done to adequately address questions on the level of soteriology.

The subject of the study is collective trauma and its manifestations in post-war Italy. The definition of collective trauma is given on the basis of the works of sociologists and its characteristics. The purpose and novelty of the work is to explain the "phenomenality" of the journalist and historian Giampaolo Pansa. The contribution he made to the Italian consciousness after the release of the books "Children of the Eagle" and "Blood of the Vanquished", devoted to methods of retaliation against (...) fascist arbitrariness during the Italian Civil War of 1943-1945, consists in explaining the bilateral collective trauma that arose as a consequence of the ideology of fascism, affecting both its supporters and its opponents. The main conclusion of the study is the following. The method of J. Alexander's cultural sociology enriched with the existential grief of A.I. Etkind is analyzed. The meaning of socio-cultural trauma can be determined by answering the questions about what crisis events we are talking about, who is responsible for them, what are the consequences of traumatic actions. Turning these questions into a narrative is the most important problem for anthropology.

The island of Palawan stretches northward from Borneo like a bridge to Luzon in the South China Sea. This tropical forest environment, rich in thousands of species of plants and animals, is home to about 50,000 people, known as the Palawan. Besides hunting with blowpipes, traps, spears, and dogs, these people also practice shifting cultivation. Hunting and gathering activities as well as work in the fields follow the alternation of two seasons, the “monsoon” and the “heat,” barat and bulag. As (...) an integral ecosystem, swidden places a high value on mobility rather than on land property. Land tenure, and recourse to physical violence of all kinds are considered unethical behavior. Social life among the Palawan is governed by a bilateral or undifferentiated kinship system, a complex customary law based on rules and values dictated by “the tradition of the Ancestors,” Adat ät Kägunggurangan.

In the history of relations between the Argentinean government and the Holy See, two ideas are permanently intertwined: signing the Concordat and defending national patronage. The changes that occurred in the 1960s indicated that exercising the right of patronage, based on the principles outlined in the Constitution, was impossible, and the peaceful establishment of the principles of bilateral relations could only be indicated through an international agreement. The Concordat signed by Argentina in 1966 removed the national patronage, but the (...) changes to the content of the Constitution were introduced only in 1994. The aim of the study is to show the concordat agreement concluded in 1966 by Argentina with the Holy See as an example of an international agreement. The main focus is the presentation of concordat standards for the institution of patronage. Due to the subject and purpose of the study, the work uses methods typical of social sciences in the legal science discipline. The dogmatic-legal method is the basis for consideration of the Concordat as a source of Argentine law, and as an auxiliary method, the historical-legal method was used to show the historical background of the presented issue.

This paper aims to further explore the potentiality of integrating key insights from virtue argumentation theory into pragma-dialectics to establish a virtuous pragma-dialectics. Drawing methodological inspiration from Gascón’s work, this paper introduces the “conditions-implications framework.” Firstly, it argues that virtues offer novel perspectives on the second-order conditions of critical discussion. Specifically, it illustrates that excessive emotional attachment and identity prejudice hinder the reasonable engagement of arguers at both individual and socio-cultural levels, and virtues play a pivotal role in overcoming these (...) irrational factors. Furthermore, integrating virtue insights into pragma-dialectics leads to two important theoretical implications: (1) an expanded fallacy theory—revealing the connection between argumentative vices and fallacies, expanding fallacies from a unilateral to a bilateral issue; (2) an expanded strategic maneuvering theory—virtue contributes to maintaining the delicate balance between dialectical reasonableness and rhetorical effectiveness. The virtue approach is anticipated to act as a facilitator rather than an obstruction to the future advancement of pragma-dialectics. (shrink)

In "Formations of World Literature and Shaw's The Man of Destiny in Chinese and Japanese Translation" Shunqing Cao and Xin Chen expand Franco Moretti's dictum that "world literature is not an object, it's a problem" to elaborate that the concept of world literature is in some sense a problematic one, which is itself under a process of problematization. Cao and Chen discuss how variation and heterogeneity contribute to a more in-depth understanding of formations of world literature. Taking the Bernar Shaw's (...) The Man of Destiny they discuss the writer's presence in world literature from a bi-lateral perspective: Shaw's work in the English-speaking West and Shaw in Asia. For the former, Shaw stands in a specific place in recent postcolonial Irish Studies and thus raise problems for their research paradigm. For the latter, Cao and Chen present an analytical comparison between a Chinese and a Japanese translation of The Man of Destiny. Cao and Chen argue that by such a bilateral approach we may recognize the importance of heterogeneity so as to obtain further reflections on present discussions of world literature. (shrink)

Schizophrenia is considered as a self-disorder with disordered local synchronous activation. Previous studies have reported widespread dyssynchrony of local activation in patients with SZ, which may be one of the crucial physiological mechanisms of SZ. To further verify this assumption, this work used a surface-based two-dimensional regional homogeneity approach to compare the local neural synchronous spontaneous oscillation between patients with SZ and healthy controls, instead of the volume-based regional homogeneity approach described in previous study. Ninety-seven SZ patients and 126 HC (...) were recruited to this study, and we found the SZ showed abnormal 2dReHo across the cortical surface. Specifically, at the global level, the SZ patients showed significantly reduced global 2dReHo; at the vertex level, the foci with increased 2dReHo in SZ were located in the default mode network, frontoparietal network, and limbic network ; however, foci with decreased 2dReHo were located in the somatomotor network, auditory network, and visual network. Additionally, this work found positive correlations between the 2dReHo of bilateral rectus and illness duration, as well as a significant positive correlation between the 2dReHo of right orbital inferior frontal gyrus with the negative scores of the positive and negative syndrome scale in the SZ patients. Therefore, the 2dReHo could provide some effective features contributed to explore the pathophysiology mechanism of SZ. (shrink)

The dominant image of courts as agencies of trial and judgment has a long history in the common law world. Yet across that region sponsorship of settlement is now widely identified as the courts’ primary responsibility, transforming them into sites where the profoundly different rationalities that ground negotiated agreement increasingly supersede those of rule-based adjudication. This study examines the work of one English court—the Mayor's and City of London Court—in sponsoring settlement and considers how that role is legitimated on both (...) propositional and symbolic levels. This evolving role raises questions about the Victorian court premises themselves. How are we to regard the now frequently empty courtrooms, designed for trial and judgment and decorated with Gothic elevations linking them symbolically with processes of medieval kingship? Should we simply see this Victorian site of contemporary settlement processes as no more than the quaint residue of a vanished era? Or can these historic features retain potency and relevance at a symbolic level, providing legitimacy for bilateral negotiation rather than the open processes of trial and judgment for which they were originally constructed?

BackgroundCognitive impairments are prevalent in patients with unipolar and bipolar depressive disorder. Considering the fact assessing cognitive functions is increasingly feasible for clinicians and researchers, targeting these problems in treatment and using them at baseline as predictors of response to treatment can be very informative.MethodIn a naturalistic, retrospective study, data from 120 patients with UDD and BDD were analyzed. Patients received 20 sessions of bilateral rTMS and were assessed regarding their depressive symptoms, sustained attention, working memory, and executive functions, (...) using the Beck Depression Inventory and Neuropsychological Test Automated Battery Cambridge, at baseline and after the end of rTMS treatment course. Generalized estimating equations and logistic regression were used as the main statistical methods to test the hypotheses.ResultsFifty-three percentage of all patients responded to treatment. In particular, 53.1% of UDD patients and 46.9% of BDD patients responded to treatment. Bilateral rTMS improved all cognitive functions except for visual memory and resulted in more modulations in the working memory of UDD compared to BDD patients. More improvements in working memory were observed in responded patients and visual memory, age, and sex were determined as treatment response predictors. Working memory, visual memory, and age were identified as treatment response predictors in BDD and UDD patients, respectively.ConclusionBilateral rTMS improved cold cognition and depressive symptoms in UDD and BDD patients, possibly by altering cognitive control mechanisms, and processing negative emotional bias.

This article examines viability of track II and III initiatives between India and Pakistan and their contribution in creating a cordial environment for track I diplomacy. The objective is the probe whether informal dialogues pave the way for states to communicate formally or their presence is cosmetic in nature. Pakistan and India share a belligerent history of bilateral relationships. Despite four wars, diplomacy has somehow remained at work between the two. Although the two countries have been engaged in official (...) and backdoor dialogues periodically, however, this diplomatic contact appeared fragile and felt prey of severity many times. Track II and Track III diplomacy initiatives were launched and sought as means to reach the end of cordiality in bilateral relationships. The methodology used in this article is qualitative with primary and secondary sources. Through analysis of semi-governmental and people to people initiative, it is found that unofficial contact between the two states has not contributed toward paving the way for track I diplomacy. Such initiatives enjoy at length in good times more, rather than converting hostility into harmony in tense times. From Neemrana Dialogue to Ashoka Theater, track II and track III were unable to substitute track I. (shrink)

. In our opinion, the processes of changing of sovereignty nowadays are among those of much significance. Presumably, if such processes (of course with much fluctuation) gain strength it will surely affect all spheres of life, including change of ideology and social psychology (the moment which is still underestimated by many analysts). Generally speaking, notwithstanding an avalanche of works devoted to the transformation of sovereignty, some topical aspects of the problem mentioned appear to have been disregarded. The present article (...) is devoted to the analysis of one of such insufficiently investigated aspects – the deliberate voluntary reduction of sovereign prerogatives. In the present paper we have tried to prove that on the whole globalization contributes to the change and reduction of nomenclature and scope of state sovereign powers, and besides it is a bilateral process: on the one hand, the factors are strengthening that fairly undermine the countries' sovereignty, on the other – most states voluntarily and deliberately limit the scope of their sovereignty.

Diplomatic relations carried out between the states are fulfilled under the protocol ruled out by the actors within the international system, which prevents any possible problems that might affect the course of bilateral relations from coming out. However, work and actions in the public arena are carried out under the protocol rules, some of which are in written form, and some of which are based on traditions used for a long period of time. Conducting the mentioned work and actions (...) under the protocol rules not only creates a discipline prevailing work environment, but also encourages employees to perform their duties in a more relaxed, peaceful, happier and more productive manner. Therefore, it is an absolute necessity to act with the attitudes and behaviors under the protocol rules both in the fulfillment of diplomatic relations and in the fulfillment of public activities. But as the protocol rules are not known well enough in Turkey, the necessity mentioned above is not obeyed. This case leads to occurance of significant defects during the implemention of services provided by public institutions in Turkey and the implementation of diplomatic relations. As a matter of fact; when examining the proceduces concerning public work and functions, and diplomatic relations in detail; one can obviously see that numerous problems are encountered which result from not implementing or mis-implementing protocol rules. This study aims to prove that more importance must be given to education on protocol rules in Turkey. (shrink)

Atypical structural properties of the brain’s white matter bundles have been associated with failing reading acquisition in developmental dyslexia. Because these white matter properties may show dynamic changes with age and orthographic depth, we examined fractional anisotropy (FA) along 16 white matter tracts in 8- to 11-year-old dyslexic (DR) and typically reading (TR) children learning to read in a fairly transparent orthography (Dutch). Our results showed higher FA values in the bilateral anterior thalamic radiations of DRs and FA values (...) of the left thalamic radiation scaled with behavioral reading-related scores. Furthermore, DRs tended to have atypical FA values in the bilateral arcuate fasciculi. Children’s age additionally predicted FA values along the tracts. Together, our findings suggest differential contributions of cortical and thalamo-cortical pathways to the developing reading network in dyslexic and typical readers, possibly indicating prolonged letter-by-letter reading or increased attentional and/or working memory demands in dyslexic children during reading.

Although the neural systems that underlie spoken language are well-known, how they adapt to evolving social cues during natural conversations remains an unanswered question. In this work we investigate the neural correlates of face-to-face conversations between two individuals using functional near infrared spectroscopy and acoustical analyses of concurrent audio recordings. Nineteen pairs of healthy adults engaged in live discussions on two controversial topics where their opinions were either in agreement or disagreement. Participants were matched according to their a priori opinions (...) on these topics as assessed by questionnaire. Acoustic measures of the recorded speech including the fundamental frequency range, median fundamental frequency, syllable rate, and acoustic energy were elevated during disagreement relative to agreement. Consistent with both the a priori opinion ratings and the acoustic findings, neural activity associated with long-range functional networks, rather than the canonical language areas, was also differentiated by the two conditions. Specifically, the frontoparietal system including bilateral dorsolateral prefrontal cortex, left supramarginal gyrus, angular gyrus, and superior temporal gyrus showed increased activity while talking during disagreement. In contrast, talking during agreement was characterized by increased activity in a social and attention network including right supramarginal gyrus, bilateral frontal eye-fields, and left frontopolar regions. Further, these social and visual attention networks were more synchronous across brains during agreement than disagreement. Rather than localized modulation of the canonical language system, these findings are most consistent with a model of distributed and adaptive language-related processes including cross-brain neural coupling that serves dynamic verbal exchanges.
