We investigate the semantics of messages, and argue that the meaning ofa message is naturally and usefully given in terms of how it affects theknowledge of the agents involved in the communication. We note thatthis semantics depends on the protocol used by the agents, and thus not only the message itself, but also the protocol appears as a parameter in the meaning. Understanding this dependence allows us to give formal explanations of a wide variety of notions including language dependence, implicature, (...) and the amount of information in a message.

The COVID-19 pandemic will likely recede only through development and distribution of an effective vaccine. Although there are many unknowns surrounding COVID-19 vaccine development, vaccine demand will likely outstrip early supply, making prospective planning for vaccine allocation critical for ensuring the ethical distribution of COVID-19 vaccines. Here, we propose three central goals for COVID-19 vaccination campaigns: to reduce morbidity and mortality, to minimise additional economic and societal burdens related to the pandemic and to narrow unjust health inequalities. We evaluate five (...) prioritisation approaches, assess their likely impact on advancing the three goals of vaccine allocation and identify open scientific questions that may alter their outcomes. We argue that no single prioritisation approach will advance all three goals. Instead, we propose a multipronged approach that considers the risk of serious COVID-19 illness, instrumental value and the risk of transmission, and is guided by future research on COVID-19-specific clinical and vaccine characteristics. While we focus this assessment on the USA, our analysis can inform allocation in other contexts. (shrink)

We suggest that the issue of constructing andverifying social procedures, which we suggestively call socialsoftware, be pursued as systematically as computer software is pursued by computer scientists. Certain complications do arise withsocial software which do not arise with computer software, but thesimilarities are nonetheless strong, and tools already exist which wouldenable us to start work on this important project. We give a variety ofsuggestive examples and indicate some theoretical work which alreadyexists.

The present paper aims to study the origin and the development of karma and rebirth theory, which was the outcome of the collective historical experiment of multiple social groups under the socially shared ideological philosophical system of Ancient India. The existing historiography looked at it as a superfi- cial system dealing with certain ideas around religion and ritual. Therefore, it missed out on the other aspects related to it, which evolved around the notion of penance and punishment. That internalizes the (...) social order and justified the unaccounted inequalities by forcing individuals to self-surrender for violation of social and legal limitations of the concerned society. This present paper is going to look at this primary idea by focusing on multiple forms of karma and rebirth and the idea of the body in the same as depicted in Manusmrti. In addi tion to this, it will also check the inter-mixture of social and religious morality in the same through the historical process of ethnicization by making the base to the existing socio-economic environment of the concerned period.

This paper aims to investigate the effect of gamification in engaging and motivating consumers for online shopping and also the use of gamification to enhance sales. Moreover, this study has also explored the ethical concerns in gamified marketing. This is a qualitative study to investigate the effect of gamification during online shopping and the ethical issues involved in gamified marketing. Semi-structured interviews with ten gamification experts are conducted and analyzed through NVivo. The themes that emerged from qualitative analysis are the (...) applicability of gamification in online retail, consumer experiences in gamified retail, and ethics and challenges in gamification. Semantic analysis is performed, and as per the viewpoint of the gamification experts, it was found that the perception of ethics in gamification is negative, which shows that there are many unethical practices in gamified marketing. This paper shows that by focusing on every relational aspect of consumer engagement, retailers can build trust and retain their most valuable stakeholders — the customers, thereby addressing the crucial negative concerns of gamified marketing. This research is one of its types to explore the significant ethical issues that affect consumers in the retail context. The undertaking of this study in an emerging economy adds further insight into gamified retail literature by generalizing the applicability of gamified studies across geographic contexts. (shrink)

We propose a model for belief which is free of presuppositions. Current models for belief suffer from two difficulties. One is the well known problem of logical omniscience which tends to follow from most models. But a more important one is the fact that most models do not even attempt to answer the question what it means for someone to believe something, and justwhatit is that is believed. We provide a flexible model which allows us to give meaning to beliefs (...) in general contexts, including the context of animal belief (where action is usually our only clue to a belief), and of human belief which is expressed in language.

This paper contributes to business ethics by focusing on consumption that is characterized by normative violence. By drawing on the work of Judith Butler this study of kajer lok—a female subaltern group of Indian domestic service providers—and their higher status clients shows how codes of status-based consumption shaped by markets, class, caste, and patriarchy create a social order that reduces kajer lok to “ungreivable” lives. Our study contributes to business ethics by focusing on exploitation and coercion in consumption rather than (...) in production and of woman rather than of men. It adds to consumer research by revealing how social distinctions not only manifest in status contests in which symbolic power is at stake but also may produce violent exploitation and ungrievable lives.

The integration of Corporate social responsibility with BusinessStrategy has been identified as a central Corporate social responsibility concept. Corporate social responsibility, it is important to understand the Key Drivers and Building Blocks that is integral to this phenomenon and which will impact the Civil Society at large. If the Indian government and private companies are serious about meeting Sustainable Development Goals, Mandated CSR has to be used as a Strategic Vehicle not only to reduce the substantial financial shortfall but Corporate (...) social responsibility as an integral part of a company’s Strategy, to help companies achieve Competitive Advantage. The paper lists down five strategic Building Blocks of Mandated CSR namely—Shared vision, Key Drivers, Dialogue, measuring impact, and Governance which provide a mental framework to think about mCSR in a novel way. The paper emphasizes the importance of Shared vision, Problem Identification, utilizing Board’s Expertise, Innovation, building network, Best Practice sharing, managing failure risk, Shareholder’s Activism, Government’s Intention, and Capacity Building.

From Kabir to Krishnamurti is a far cry. For, they are separated one from the other by over five centuries. But quantitative measurement of this distance has a qualitative aspect which cannot be measured in any time-scale. Two great seers lived in two completely different worlds-with no comparison between the two. And yet they expressed their thoughts and experience not only in a similar language but almost in identical terms. In these two streams of thought represented by Kabir and Krishnaji, (...) the authors note a fascinating parallelism. These streams run parallel to each other-and yet they meet from time to time-at the intersections between the two approaches to life. J. Krishnamurti and Sant Kabir focuses on these meeting points between the two approaches to life. The book also presents the intersections between the writings and sayings of Kabir and Krishnaji.

The aim of this meta-analysis was to evaluate the effects of complex training on sprint, jump, and change of direction ability among soccer players. After an electronic search, 10 peer-reviewed articles were considered in the meta-analysis. The athletes included in this meta-analysis were amateur to professional level male soccer players. These studies incorporated CT in soccer players who were compared to a control group. Significant moderate to large improvements were observed in the CT group [sprint: standard mean difference = 0.92–1.91; (...) jump: SMD = 0.96–1.58; COD: SMD = 0.97–1.49] when compared to control groups. Subgroup analysis were also conducted based on age, duration, and competitive level. The beneficial effects of CT were greater in players <18 vs. ≥18 years, after ≥8 vs. <8 weeks and among professional vs. amateur players. In conclusion, regular soccer training programs may be supplemented with CT to improve sprint, jump, and COD performance. A longer duration of CT seems to be optimal in improving the physical abilities of soccer players. Professional players and <18 years players may benefit more from CT program. (shrink)

We offer a probabilistic model of rational consequence relations (Lehmann and Magidor, 1990) by appealing to the extension of the classical Ramsey-Adams test proposed by Vann McGee in (McGee, 1994). Previous and influential models of nonmonotonic consequence relations have been produced in terms of the dynamics of expectations (Gärdenfors and Makinson, 1994; Gärdenfors, 1993).'Expectation' is a term of art in these models, which should not be confused with the notion of expected utility. The expectations of an agent are some form (...) of belief weaker than absolute certainty. Our model offers a modified and extended version of an account of qualitative belief in terms of conditional probability, first presented in (van Fraassen, 1995). We use this model to relate probabilistic and qualitative models of non-monotonic relations in terms of expectations. In doing so we propose a probabilistic model of the notion of expectation. We provide characterization results both for logically finite languages and for logically infinite, but countable, languages. The latter case shows the relevance of the axiom of countable additivity for our probability functions. We show that a rational logic defined over a logically infinite language can only be fully characterized in terms of finitely additive conditional probability. (shrink)

This article looks at the contribution made by Ambalavaner Sivanandan to black politics and organising in Britain. It reviews some of his most important writings and analyses their significance and influence on black activism and race studies. Specifically, the article looks at the ways in which class and race intersected in his work and his critical stance towards political elites and advocacy for radical politics.

This article was written shortly after the death of Benedict Anderson. It contextualizes Anderson's contribution to studies of nationalism and the Global South, particularly Asia. It then revisits some of the key debates of Anderson’s scholarship and its particular significance and importance to the study of South Asia.

This book will be of great interest to all students of Hinduism, students of both Eastern and Western philosophy, and spiritual seekers who wish to better understand this ancient Indian tradition of non-dualist thought.

BackgroundExercise is primarily sustained by energy derived from lipids, and glucose. Substrate utilization is the pattern by which these fuel sources are used during activity. There are many factors that influence substrate utilization. We aim to delineate the effect of exercise intensity and body composition on substrate utilization.ObjectiveThe objective of our study was to discern the differences in substrate utilization profiles during a maximal and submaximal graded exercise test, and to determine the extent to which body composition influences substrate utilization (...) during the exercise tests.MethodsA total of 27 male athletes, 32.5 ± 11 years of age, were recruited for this study. Body composition was analyzed using a bioelectrical impedance analyzer. Maximal and submaximal exercise tests were performed on a treadmill. A novel graded submaximal treadmill protocol was used for the submaximal test.ResultsAverage percent body fat was 15.8 ± 5%. Average maximal oxygen consumption was 47.6 ± 9 mL/kg/min, while the average exercise intensity at which participants were shifting to glucose predominance for energy during the maximal and submaximal tests were 76 ± 8.3% and 58.4 ± 21.1%, respectively. A paired-samples t-test was conducted to compare percent VO2max at crossover point in maximal and submaximal graded exercise tests. There was a significant difference in percent VO2max at the crossover point for maximal and submaximal tests. A linear regression was performed to elucidate the interaction between exercise intensity at the crossover point and body composition during a maximal and submaximal graded exercise test. There was a significant effect of PBF on percent VO2max at crossover point during the maximal graded exercise test [F = 9.10, P = 0.006] with an R2 of 0.245. However, there was no significant effect of PBF on percent VO2max at crossover point during the submaximal graded exercise test.ConclusionSubstrate utilization, represented by the crossover point, is dependent on the rate of increase in exercise intensity. At maximal efforts, the crossover to carbohydrates from fats as the predominant fuel source occurs at a significantly later stage of percent VO2max than at submaximal efforts. Furthermore, body composition represented by PBF is a significant predictor of substrate utilization during maximal efforts. Athletes with a relatively higher PBF are more likely to have increased lipid oxidation during high intensity exercises than those with a lower body fat percentage. (shrink)

BackgroundNeuropsychological profile of Indian Duchenne muscular dystrophy subjects remains unidentified and needs to be evaluated.MethodsA total of 69 DMD and 66 controls were subjected to detailed intelligence and neuropsychological assessment. The factor indexes were derived from various components of Malin’s Intelligence Scale for Indian Children and Rey Auditory Verbal Learning Test.ResultsPoor verbal and visual memory profiles were demonstrated by DMDs, which include RAVLT-immediate recall, RAVLT-delayed recall, Rey–Osterrieth complex figure test -IR, and RCFT-DR. RAVLT-memory efficiency index demonstrated poor verbal memory efficiency. (...) Significant differences in the functioning of working memory axis [RAVLT T1, recency T1, Digit Span Backward ] were observed along with reduced performance in visuomotor coordination, visuospatial, and visual recognition abilities. Block designing efficiency index and attention fraction showed a normal performance in DMD kids.ConclusionWorking memory deficits were found to be the crucial element of cognitive functioning in DMD cases. Working memory interventions may be beneficial to improve the neuropsychological profile in DMD. (shrink)

Although the path-integral formalism is known to be equivalent to conventional quantum mechanics, it is not generally obvious how to implement path-based calculations for multi-qubit entangled states. Whether one takes the formal view of entangled states as entities in a high-dimensional Hilbert space, or the intuitive view of these states as a connection between distant spatial configurations, it may not even be obvious that a path-based calculation can be achieved using only paths in ordinary space and time. Previous work has (...) shown how to do this for certain special states; this paper extends those results to all pure two-qubit states, where each qubit can be measured in an arbitrary basis. Certain three-qubit states are also developed, and path integrals again reproduce the usual correlations. These results should allow for a substantial amount of conventional quantum analysis to be translated over into a path-integral perspective, simplifying certain calculations, and more generally informing research in quantum foundations.

Subset Spaces were introduced by L. Moss and R. Parikh in [8]. These spaces model the reasoning about knowledge of changing states.In [2] a kind of subset space called intersection space was considered and the question about the existence of a set of axioms that is complete for the logic of intersection spaces was addressed. In [9] the first author introduced the class of directed spaces and proved that any set of axioms for directed frames also characterizes intersection spaces.We give (...) here a complete axiomatization for directed spaces. We also show that it is not possible to reduce this set of axioms to a finite set. (shrink)

We propose a new relevance sensitive model for representing and revising belief structures, which relies on a notion of partial language splitting and tolerates some amount of inconsistency while retaining classical logic. The model preserves an agent's ability to answer queries in a coherent way using Belnap's four-valued logic. Axioms analogous to the AGM axioms hold for this new model. The distinction between implicit and explicit beliefs is represented and psychologically plausible, computationally tractable procedures for query answering and belief..

We give an example of a polynomial time algorithm for a particular algorithmic problem involving vagueness and visual indiscriminability, namely sock sorting.

Deontic Logic goes back to Ernst Mally’s 1926 work, Grundgesetze des Sollens: Elemente der Logik des Willens [Mally. E.: 1926, Grundgesetze des Sollens: Elemente der Logik des Willens, Leuschner & Lubensky, Graz], where he presented axioms for the notion ‘p ought to be the case’. Some difficulties were found in Mally’s axioms, and the field has much developed. Logic of Knowledge goes back to Hintikka’s work Knowledge and Belief [Hintikka, J.: 1962, Knowledge and Belief: An Introduction to the Logic of (...) the Two Notions, Cornell University Press] in which he proposed formal logics of knowledge and belief. This field has also developed quite a great deal and is now the subject of the TARK conferences. However, there has been relatively little work combining the two notions of knowledge (belief) with the notion of obligation. (See, however, [Lomuscio, A. and Sergot, M.: 2003, Studia Logica 75 63–92; Moore, R. C.: 1990, In J. F. Allen, J. Hendler and A. Tate (eds.), Readings in Planning, Morgan Kaufmann Publishers, San Mateo, CA]) In this paper we point out that an agent’s obligations are often dependent on what the agent knows, and indeed one cannot reasonably be expected to respond to a problem if one is not aware of its existence. For instance, a doctor cannot be expected to treat a patient unless she is aware of the fact that he is sick, and this creates a secondary obligation on the patient or someone else to inform the doctor of his situation. In other words, many obligations are situation dependent, and only apply in the presence of the relevant information. Thus a case for combining Deontic Logic with the Logic of Knowledge is clear. We introduce the notion of knowledge based obligation and offer an S5, history based Kripke semantics to express this notion, as this semantics enables us to represent how information is transmitted among agents and how knowledge changes over time as a result of communications. We consider both the case of an absolute obligation (although dependent on information) as well as the (defeasible) notion of an obligation which may be over-ridden by more relevant information. For instance a physician who is about to inject a patient with drug d may find out that the patient is allergic to d and that she should use d′ instead. Dealing with the second kind of case requires a resort to non-monotonic reasoning and the notion of justified belief which is stronger than plain belief, but weaker than absolute knowledge in that it can be over-ridden. This notion of justified belief also creates a derived notion of default obligation where an agent has, as far as the agent knows, an obligation to do some action a. A dramatic application of this notion is our analysis of the Kitty Genovese case where, in 1964, a young woman was stabbed to death while 38 neighbours watched from their windows but did nothing. The reason was not indifference, but none of the neighbours had even a default obligation to act, even though, as a group, they did have an obligation to take some action to protect Kitty. (shrink)

Both the Beth definability theorem and Craig's lemma (interpolation theorem from now on) deal with the issue of the entanglement of one language L1 with another language L2, that is to say, information transfer—or the lack of such transfer—between the two languages. The notion of splitting we study below looks into this issue. We briefly relate our own results in this area as well as the results of other researchers like Kourousias and Makinson, and Peppas, Chopra and Foo.Section 3 does (...) contain one apparently new theorem.

Gluten ataxia is a rare immune-mediated neurological disorder caused by the ingestion of gluten. The diagnosis is not straightforward as antibodies are present in only up to 38% of patients, but often at lower titers. The symptoms of ataxia may be mild at the onset but lead to permanent damage if remain untreated. It is characterized by damage to the cerebellum however, the pathophysiology of the disease is not clearly understood. The present study investigated the neurochemical profile of vermis and (...) right cerebellum and structural changes in various brain regions of patients with gluten ataxia and compared it with healthy controls. Volumetric 3-D T1 and T1-weighted magnetic resonance imaging in the three planes of the whole brain and single-voxel 1H- magnetic resonance spectroscopy of the vermis and right cerebellum were acquired on 3 T human MR scanner. The metabolite concentrations were estimated using LC Model while brain volumes were estimated using the online tool volBrain pipeline and CERES and corrected for partial volumes. The levels of neuro-metabolites were found to be significantly lower in vermis, while N-acetyl aspartate + N-acetyl aspartate glutamate and glycerophosphocholine + phosphocholine was lower in cerebellum regions in the patients with gluten ataxia compared to healthy controls. A significant reduction in the white matter of ; reduction in the volumes of cerebellum lobe and thalamus while lateral ventricles were increased in the patients with gluten ataxia compared to healthy controls. The reduced neuronal metabolites along with structural changes in the brain suggested neuronal degeneration in the patients with gluten ataxia. Our preliminary findings may be useful in understanding the gluten-induced cerebral damage and indicated that MRI and MRS may serve as a non-invasive useful tool in the early diagnosis, thereby enabling better management of these patients.
