This thesis investigates two main issues concerning the behavior of rational agents, preference dynamics and agent diversity. -/- We take up two questions left aside by von Wright, and later also the multitude of his successors, in his seminal book Logic of Preference in 1963: reasons for preference, and changes in preference. Various notions of preference are discussed, compared and further correlated in the thesis. In particular, we concentrate on extrinsic preference. Contrary to intrinsic preference, extrinsic preference is reason-based, i.e. (...) one's preference for one option over another has a reason. A logical model is proposed and its properties are determined. Dynamics come in naturally, since reasons for the preferences can change. Logical systems and formal results regarding dynamical preference change are then presented. -/- Preference arises from comparisons between alternatives. A first option is to compare situations. Abstractly speaking, preferences are in this case between propositions, viewed as sets of possible worlds. The reasons can then be based on a `betterness' relation over possible worlds. Propositional preference arises as a lift from this primitive relation. A standard modal logical approach is taken and we use a modality for the betterness relation in the language. We then model preference change by techniques from dynamic epistemic logic (DEL), where a typical action, e.g. a suggestion or a command can change the betterness ordering of the worlds, and thereby the propositional preference. Dynamic reduction axioms are obtained to encode exactly how such a change takes place. We obtain a complete dynamic preference logic. -/- A second option is to compare objects as such. Concretely, properties of the objects often determine the preference over the objects. Properties are now the reasons. Inspired by Optimality Theory (OT), we propose a priority sequence, an ordering of properties. Various ways of getting a preference from the priority sequence are investigated, though we mostly follow the OT approach. We use a fragment of first-order logic to describe the situation. Here, on the dynamic side, it is priority change that leads to preference change. Using the DEL methodology again we propose a complete set of reduction axioms concerning the possible dynamic operations on priority sequences. -/- Not surprisingly, the above two views are closely related. After all, possible worlds can be thought of as objects! On the basis of a systematic comparison of the two views, we develop a two level perspective, in which the models themselves are structured in layers. In particular, correspondence results between the changes at the level of the possible worlds and the changes at the level of the priority sequences are proved. We end up by sketching a two-level preferential predicate logic to describe more complex circumstances in which situations and objects are compared simultaneously. -/- But we do not see this as the whole story. Preference does not live by itself, it is often intermingled with epistemic notions of knowledge and belief. One can have different intuitions about how this entanglement operates. A few options are discussed, and proposals for logical models are presented. When moving to dynamics, we now see a picture of knowledge update, belief revision and preference change taking place symbiotically, often unconsciously as in real life. -/- The resulting picture in the thesis is one of agents that process information and adjust beliefs and preferences in many different ways. There is no logically prescribed unique norm for doing this. The second part of the thesis takes this general phenomenon of diversity of agents as its focus, since it raises many issues for logical systems and the idealized agents which they normally presuppose. In reality, agents can differ across a wide spectrum of cognitive abilities and habits: in their memory capacity, observation power, inferential power, introspective ability, and revision policies when facing new information. -/- Two kinds of agents, perfect recall agents, and memory-free agents are studied thoroughly, in the setting of playing games. We show how current dynamic logics can be `parametrized' to allow for this memory diversity, with new characterizations of agent types resulting in complete dynamic-epistemic logics. The other dimension of the reality of diverse agents is that, however different they are, they often do manage to coordinate with each other successfully. While this theme has been prominent in game theory and multi-agent systems, it has received hardly any attention in logic. We analyze this interaction between different agents by looking at concrete scenarios which model their types explicitly. -/- Finally, we analyze the issue of agent diversity in its generality, discussing what dynamic logics would have to look like to become a full-fledged account of agents of different capacities and tendencies that pursue and sometimes achieve their goals in irreducibly social settings. -/- .

Every scientific or intellectual movement is founded upon basic assumptions and hypotheses that shape its specifically formulated philosophy. This study seeks to explore and explicate the basic philosophical underpinnings of grey systems theory, as well as the paradigm governing its postulates. The study, more specifically, scrutinizes the underlying principles of GST from the perspective of postmodern philosophy. To accomplish this, the epistemology, ontology, human nature, and methodology of GST are substantially investigated in the light of postmodern philosophy. The study draws (...) on Burrell and Morgan’s framework to reveal the paradigm underlying the philosophy of GST. Results demonstrate that GST is an anti-realistic, anti-positivistic, and non-deterministic theory which is inherently pluralistic and ideographic. Based on the principles of GST, change is an indispensable dimension of human speculation about the world and systems, and knowledge is ceaselessly reproduced as new information is collected. As a result, knowledge, narratives, theories and scientific laws are dynamically changed. GST, then, is remarkably compatible with the foundations of postmodern thought and it could be regarded as a postmodern theory governed by a humanistic paradigm. (shrink)

Building on recent work by Yale Weiss, we study conditional logics in the intuitionistic setting. We consider a number of semantic conditions which give rise, among others, to intuitionistic counterparts of Lewis’s logic VC and Stalnaker’s C2. We show how to obtain a sound and complete axiomatization of each logic arising from a combination of these conditions. On the way, we remark how, in the intuitionistic setting, certain classically equivalent principles of conditional logic come apart, and how certain logical connections (...) between different principles no longer hold.

What is feminist philosophy? A difficult question for feminist scholars in China. Women's studies in the Chinese mainland are characteristically policy‐oriented, geared to practical concerns and moral urgency. Empirical research projects engage many pressing social issues related to the changing situation of women in a rapid marketification of society and commercialization of culture since the post‐1978 reform movement. Here are some examples: migrant female workers and their working conditions in the urban centers; the impact of rural industrialization on women in (...) the countryside: discrimination against women in employment as well as in other aspects of social life; marriage and sexual relations. What follows in this article however, represents an effort to identify and categorize trends in emerging feminist theories. The main questions that might be seen as in one way or another philosophical are located in the historical context of the transformation of Chinese socialism. As we have only very limited access to publications in Hong Kong and Taiwan, to avoid mispresentation we regret that we cannot discuss the feminist work developed in these areas. (shrink)

Artificial intelligence (AI) is increasingly expected to disrupt the ordinary functioning of society. From how we fight wars or govern society, to how we work and play, and from how we create to how we teach and learn, there is almost no field of human activity which is believed to be entirely immune from the impact of this emerging technology. This poses a multifaceted problem when it comes to designing and understanding regulatory responses to AI. This article aims to: (i) (...) defend the need for a novel conceptual model for understanding the systemic legal disruption caused by new technologies such as AI; (ii) to situate this model in relation to preceding debates about the interaction of regulation with new technologies (particularly the ‘cyberlaw’ and ‘robolaw’ debates); and (iii) to set out a detailed model for understanding the legal disruption precipitated by AI, examining both pathways stemming from new affordances that can give rise to a regulatory ‘disruptive moment’, as well as the Legal Development, Displacement or Destruction that can ensue. The article proposes that this model of legal disruption can be broadly generalisable to understanding the legal effects and challenges of other emerging technologies. (shrink)

This paper sheds light on the incongruent findings concerning the relationship between family involvement and firms’ corporate social responsibility. While prior studies have mainly taken the perspective of families’ socioemotional wealth preservation, we approach this relationship from the perspective of behavioral agency theory, highlighting the important role played by CEOs’ family memberships. Specifically, we posit that family firms are more likely to invest in CSR when their CEOs are members of the controlling families. Furthermore, we examine how family firms can (...) employ long-term incentives to encourage non-family CEOs to act in the interests of the controlling families to preserve SEW and thus enhancing family firms’ CSR performance. We tested our hypotheses using hand-collected data of family firms included in the S&P 500 index, in the period of 2003–2010. The empirical findings support our hypotheses that family firms with family members as the CEOs have better CSR performance and family firms tend to provide a high level of long-term incentives to non-family than family CEOs. In addition, long-term incentives strongly motivate CEOs to improve firms’ CSR performance, regardless of their family memberships. (shrink)

Nowadays, a significant portion of corporate social responsibility (CSR) communication takes place online. The current article attends to an essential, yet often overlooked element of online CSR communication: cross-sectoral hyperlink networks. The article argues that corporations build cross-sectoral hyperlink networks with nongovernmental organizations (NGOs) as a form of CSR communication to manage social issues. Using social network analysis, this article analyzes the hyperlink network data between 136 corporations and 94 international NGOs. Findings show that corporations’ cross-sectoral ties serve as a (...) communication strategy to respond to salient issues and manage issues that are relevant to these corporations. NGOs’ tenure and network dynamics are also found to significantly affect the number of cross-sectoral ties built with corporations. (shrink)

The purpose of cause-related marketing (CRM) is to publicise and capitalise on a firm's corporate social performance (CSP) by enhancing its legitimacy in the eyes of its stakeholders. This study focuses on the firm's internal stakeholders - i.e. its employees - and the extent of their involvement in the selection of social campaigns. Whilst the difficulties of managing a firm that has lost or damaged its legitimacy in the eyes of its employees are well known, little is understood about the (...) extent to which managers and their social partners listen to and involve their employees in the legitimation process. Through telephone interviews with non-profit organisations and senior managers of service sector firms, the extent of employee involvement in CRM campaigns and the perceived benefits of doing so are investigated. Amongst other things, we find that (i) the extent of employee participation varies significantly across firms; (ii) larger CRM campaigns tend to be managed centrally with relatively less employee participation than smaller ones and (iii) financial services firms are more likely to make CRM decisions centrally, with relatively less employee participation than retail services firms.

We aim to investigate the effect of corporate environmental responsibility (CER) engagement on investors' reactions. We also explore heterogeneity of this impact among different types of companies and different company's market performance. We use panel data models and quantile regression based on data related to firms listed on the A-share China security market and the final sample consists of 3,776 firm-year observations. The results show that CER engagement has a significant positive impact on investors' investment decisions. Further, investors are more (...) sensitive to CER engagement of high energy-consumption companies and no matter the company is a state-owned or a non-state-owned, CER engagement has a significant positive impact on investors' reactions. CER engagement has a significant positive impact on investors' reactions in all quantiles except one and the promoting effect increases first and then decreases with the growth of corporate market value from lower to upper quantiles.

As a way of human-computer interaction, game-based assessment is more suitable for young children because it is situational, interesting, and effective. National identity is an important factor affecting the overall development of young children and the future development of a country, which has attracted extensive attention from researchers. Nevertheless, the assessment of young children's national identity is still based on traditional evaluation, including questionnaires and interviews, which have the limitations of being inaccurate, dull, and time-consuming. To understand the characteristics of (...) children's national identity, it is necessary to use scientific and interactive assessment methods. The present study investigated whether the game-based assessment we developed specifically would be an appropriate tool to measure young children's national identity. The results show that the game-based assessment had good item discrimination. Exploratory factor analysis demonstrated the game covered three aspects: national cognition mastery, national emotion engagement, and national behavior tendency. The confirmatory factor analysis suggested that the model with three factors fit the data well. The internal consistency, the split-half reliability, and the test-retest reliability meet standards. Overall, the results indicated that this game can be successfully used to assess young children's national identity with acceptable validity and reliability. Our study provides strong evidence for the use of human-computer interaction in child measurement. These findings are the first to demonstrate the promise of game-based assessment in assessing children's national identity reliably and effectively. (shrink)

The rapid worldwide spread of COVID-19 forced many countries to enforce complete lockdown and strict quarantine policies. The strict lockdown and quarantine affect the psychological state of people toward cryptocurrency. The current research aims to examine the effect of COVID-19 on Bitcoin prices concerning cumulative deaths and confirmed cases. The research comprises daily data from January 20, 2020, to April 30, 2020, during the initial worldwide breakout of COVID-19. This research employed the augmented Dickey-Fuller test to check the stationarity of (...) data, the co-integration test for the interdependency of variables, and the vector error correction model for identifying the direction and long or short-run relationship between Bitcoin prices and COVID-19. The research results show that Bitcoin prices are negatively significant and related to COVID-19 in the short-run. A unidirectional relationship between Bitcoin prices and cumulative deaths is also observed. Investors and the public’s psychological state were positively significant to Bitcoin prices in the long-term because of cashless transactions, unbanked, and less risky virus traveling. The second reason behind the positive psychological relation is un-centralization and easy-to-make payments by Bitcoin. This study’s finding provides timely evidence to decision-makers on Bitcoin price volatility and its impacts on the public’s psychological states regarding COVID-19. (shrink)

Service process optimization is conducive to the innovation of enterprise services, but the poor logic design of multiple touchpoints can easily lead to problems in the service process, such as scattered layouts and repeated paths. Aiming at the promotion of service innovation and user experience, this paper takes the optimization of a single service touchpoint as the prerequisite and proposes a service process optimization method based on service touchpoint association and the design structure matrix. The association of service touchpoints is (...) categorized into two types, namely, noncoupled and coupled association. The DSM is used to describe the two types of association between service touchpoints, and the matrix operation is used for modular identification and layering of the two kinds of association. Finally, through the above steps, the problematic service process was replanned. By using the service process optimization of a new retail convenience store as an example, the service process is divided into 6 relatively independent modules, and the order of module execution is arranged. Moreover, the optimal service process of the convenience store system is determined, and the method is verified to be feasible. Through optimization both from single service touchpoint and service process modularization, the study provides a reference for process optimization of the complex service system. (shrink)

“Parting is such sweet sorrow.” Taste metaphors provide a rich vocabulary for describing emotional experience, potentially serving as an adaptive mechanism for conveying abstract emotional concepts using concrete verbal references to our shared experience. We theorized that the popularity of these expressions results from the close association with hedonic valence shared by these two domains of experience. To explore the possibility that this affective quality underlies the semantic similarity of these domains, we used a behavioral “odd-one-out” task in an online (...) sample of 1059 participants in order to examine the semantic similarity of concepts related to emotion, taste, and color, another rich source of sensory metaphors. We found that the semantic similarity of emotion and taste concepts was greater than that of emotion and color concepts. Importantly, the similarity of taste and emotion concepts was strongly related to their similarity in hedonic valence, a relationship which was also significantly greater than that present between color and emotion. These results suggest that the common core of valence between taste and emotion concepts allows us to bridge the conceptual divide between our shared sensory environment and our internal emotional experience.

University spin-outs, creating businesses from university intellectual property, are a relatively common phenomena. As a knowledge transfer channel, the spin-out business model is attracting extensive attention. In this paper, the impacts of six equities on the acquisition of USOs, including founders, university, banks, business angels, venture capitals, and other equity, are comprehensively analyzed based on theoretical and empirical studies. Firstly, the average distribution of spin-out equity at formation is calculated based on the sample data of 350 UK USOs. According to (...) this distribution, a radial basis function neural network model is employed to forecast the effects of each equity on the acquisition. To improve the classification accuracy, the novel set-membership method is adopted in the training process of the RBF NN. Furthermore, a simulation test is carried out to measure the effects of six equities on the acquisition of USOs. The simulation results show that the increase of university’s equity has a negative effect on the acquisition of USOs, whereas the increase of remaining five equities has positive effects. Finally, three suggestions are provided to promote the development and growth of USOs. (shrink)

This study aimed to investigate the relationship of employee growth mindset with innovative behavior and the mediating role of use of strength as well as the moderating role of strengths-based leadership in this relationship. Data with a sample of 244 employees working in diverse Chinese organizations were collected at two points in time. Results of bootstrapping analyses demonstrated that growth mindset is positively related to innovative behavior, employee strengths use partially mediates the positive relationship of growth mindset with innovative behavior, (...) and strengths-based leadership strengthens the direct relationship between employee growth mindset and innovative behavior and the indirect relationship of employee growth mindset with innovative behavior via strengths use. This study advances growth mindset and innovative behavior theories and research. (shrink)

Acoustic emission technique is a common approach to identify the damage of the refractories; however, there is a complex problem since there are as many as fifteen involved parameters, which calls for effective data processing and classification algorithms to reduce the level of complexity. In this paper, experiments involving three-point bending tests of refractories were conducted and AE signals were collected. A new data processing method of merging the similar parameters in the description of the damage and reducing the dimension (...) was developed. By means of the principle component analysis for dimension reduction, the fifteen related parameters can be reduced to two parameters. The parameters were the linear combinations of the fifteen original parameters and taken as the indexes for damage classification. Based on the proposed approach, the Gaussian mixture model was integrated with the Bayesian information criterion to group the AE signals into two damage categories, which accounted for 99% of all damage. Electronic microscope scanning of the refractories verified the two types of damage. (shrink)

Sociologists often imagine society as spaces, yet how social spaces are related remains ambiguous in most theories. In developing his field theory, Bourdieu used extensively the concept of homology to describe the structural similarities across fields, but he had not taken seriously the spaces between fields or how fields are related to each other. Adopting the Simmelian approach of formal sociology, this article outlines six basic social forms by which social spaces are related. It argues that relations between social spaces (...) can be understood along two dimensions: heterogeneity and social distance. In terms of heterogeneity, social spaces can be kindred, symbiotic or oppositional. In terms of social distance, they can be linked, nested or overlapping. These social forms of interspatial relations are constituted by the boundary work of a variety of actors, including guardians, brokers and space travellers. The article provides a general vocabulary for thinking about how social spaces are related and how they interact across boundaries. (shrink)

Understanding the neural basis of schizophrenia (SZ) is important for shedding light on the neurobiological mechanisms underlying this mental disorder. Structural and functional alterations in the anterior cingulate cortex (ACC), dorsolateral prefrontal cortex (DLPFC), hippocampus, and medial prefrontal cortex (MPFC) have been implicated in the neurobiology of SZ. However, the effective connectivity among them in SZ remains unclear. The current study investigated how neuronal pathways involving these regions were affected in first-episode SZ using functional magnetic resonance imaging (fMRI). Forty-nine patients (...) with a first-episode of psychosis and diagnosis of SZ—according to the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision—were studied. Fifty healthy controls (HCs) were included for comparison. All subjects underwent resting state fMRI. We used spectral dynamic causal modeling (DCM) to estimate directed connections among the bilateral ACC, DLPFC, hippocampus, and MPFC. We characterized the differences using Bayesian parameter averaging (BPA) in addition to classical inference (t-test). In addition to common effective connectivity in these two groups, HCs displayed widespread significant connections predominantly involved in ACC not detected in SZ patients, but SZ showed few connections. Based on BPA results, SZ patients exhibited anterior cingulate cortico-prefrontal-hippocampal hyperconnectivity, as well as ACC-related and hippocampal-dorsolateral prefrontal-medial prefrontal hypoconnectivity. In summary, spectral DCM revealed the pattern of effective connectivity involving ACC in patients with first-episode SZ. This study provides a potential link between SZ and dysfunction of ACC, creating an ideal situation to associate mechanisms behind SZ with aberrant connectivity among these cognition and emotion-related regions.

In families, mothers and fathers may hold the same or different levels of theories of intelligence. This congruence and discrepancy may influence parental involvement in children’s education. The current study examined how both parents’ theories of intelligence and the direction and degree of the discrepancy of parents’ intelligence theories influence maternal and paternal involvement separately. We measured 1,694 matched pairs of parents’ theories of intelligence and educational involvement, and examined the relationships using linear regressions and polynomial regressions with response surface (...) analysis. The results showed that 1) the mother’s intelligence theory positively related to both paternal involvement and maternal involvement, but the father’s intelligence theory only positively related to paternal involvement; 2) when the parents’ theories of intelligence reached congruence, the parents’ theories of intelligence are positively related to both maternal and paternal involvement; 3) when the parents’ theories of intelligence have discrepancy, the maternal involvement is higher while the mother’s intelligence theory’s level is more incremental than father’s; and 4) when the parents’ theories of intelligence have discrepancy, more discrepancy of parents’ theories of intelligence is related to more paternal involvement. This study revealed the significance of mother’s role in education, highlighted the importance of parents’ congruence and discrepancies in beliefs, examined how parents’ beliefs impact their own behavior and their couple’s behavior.

By PFM, we mean a finitely generated module over a principal ideal domain; a linear sentence is a sentence that contains no disjunctive and negative symbols. In this paper, we present an algorithm which decides the truth for linear sentences on a given PFM, and we discuss its time complexity. In particular, when the principal ideal domain is the ring of integers or a univariate polynomial ring over the field of rationals, the algorithm is polynomial-time. Finally, we consider some applications (...) to Abelian groups. (shrink)

Prudence is in order to achieve sustainability of good behavior and political contingencies applicable to deal with the kind of intellectual. To prudence and the recent recovery of Modern arrogant different alternative, one should take into account the distinctive features is that it reflects how deeply the plight of human behavior. These characteristics of practical wisdom through the words to define the history, theory, practice, structure, quality and other aspects of the audience to identify, they in this magazine is divided (...) into two parts in the statement. This first section highlights the contingency, pluralism and practical these conditions, and through its specification, design consideration and implementation of these expressions to define the set of practical wisdom. Wise actors is such a person, he balanced a variety of incommensurability of good insight into the strategy of a variety of possible actions, and in a proper and timely manner with interactive collaboration with others. Prudence is the intelligence suited to managing contingency on behalf of good action and political sustainability. In order to recuperate prudence as an alternative to late-modern hubris, one should consider how its distinctive features reflect deep predicaments of human action. These features are identified through the history, theory, practice, structure, character, and audiences defining prudential discourse, and are set out in two installments in this journal. This first installment emphasizes conditions of contingency, plurality, and praxis, and defines prudence in terms of its normative, calculative, and performative articulations. The prudent actor is one who balances incommensurable goods, discerns probable courses of action, and interacts with others in an appropriate and timely manner. (shrink)

With increased global competition and the advent of the knowledge economy, developing graduate students’ ability to innovate in their research has become a core focus of graduate education. Graduate students’ perceived help and assistance from supervisors is one of the key resources for research innovation. This study explored the relationships between graduate students’ perceived supervisor support and their innovative behavior in research, and examined the mediation effect of creative self-efficacy, their confidence in abilities to generate creative ideas or produce creative (...) outcomes. Survey data were collected from a sample of 996 Chinese graduate students. The results revealed that academic support was negatively related to idea generation and idea search; personal support was positively related to overcoming obstacles; autonomy support was positively related to all factors of innovative behavior except overcoming obstacles and innovation outputs. The mediation analysis suggested that creative self-efficacy significantly mediated the relationship between academic support and graduate students’ innovative behavior in research. The results of this study highlight the significance of both supervisor support and creative self-efficacy in developing graduate students’ research innovation. The findings have significant implications for stimulating students’ research innovation and for improving the quality of graduate education. (shrink)

We look here at how the Chinese socio-cultural system re-created its own local order in the form of a discipline which is specific to the country, “xinwen chuanboxue”. (shrink)

This article formulates the “enigma of time” as the paradoxical compatibility between the apparent completeness of a temporal object’s presence and the actual incompleteness of its manifestation. Proceeding with the methodological assumption that this paradox cannot be “solved” by positing an atemporal foundation, I point to a constant risk in Husserl’s transcendental phenomenology that the temporality of temporal phenomena is traced to an atemporal activity arranging equally atemporal contents—and thereby is explained away rather than explained. The risk was already recognizable (...) in the “schematic model” of apprehension, and it persisted in the foundationalist interpretation of “absolute time-consciousness.” By contrast, I suggest a hermeneutics that takes time seriously, which comprehends the paradox and make it the productive core of philosophizing. Only in this way can time cease to be a petrifying impasse and instead redefine the landscape of philosophy. (shrink)

I argue that conventionalists should construe a posteriori necessity as restricted necessity. I take Sidelle’s defence of the conventionalist explanation of a posteriori necessity against the contingency problem as the starting point. Sidelle construes a posteriori necessity as unrestricted necessity and then argues that a posteriori necessity is to be considered under a fixed convention and is thus irrelevant to the contingent nature of our linguistic conventions. I offer a different solution to the contingency problem. I argue that conventionalists should (...) construe a posteriori necessity as restricted necessity based upon a use-based meta-semantic picture. Restricted necessity is contingent in a broader sense and does not conflict with the contingency of conventions. My solution allows conventionalists to explain a posteriori necessity as restricted necessity. I show that the realist’s arguments for a posteriori necessity are unconvincing in regard to real modal features and a posteriori necessity as unrestricted necessity. We thus have good reason to continue to accept a posteriori necessity as restricted necessity under the conventionalist explanation. (shrink)
