A number of conditioning experiments utilize food as a reward. Hunger is considered to be a critical factor governing the animal's behavior in these experiments. Despite its significance, most theories of animal conditioning fail to take hunger into consideration while analyzing the behavioral data. In this paper, we analyze the neuroscientific data supporting the hypothesis that hunger and food consumption affect the brain's dopamine system, which in turn governs the animal's behavior. According to this hypothesis, chronic hunger results in a (...) decrease in the extra-cellular dopamine levels in the animal's brain. This decrease is believed to trigger a series of reactions that increase the responsivity of the phasic dopamine system. A direct consequence of this is an increased vigor of all dopamine-dependent behaviors. The level of extra-cellular dopamine is also modulated by the process of food consumption via the neurotransmitter Acetylcholine. Food consumption raises the dopamine above the baseline level. This rise depends on the animals' hunger, which when satisfied increases the level of Acetylcholine, which causes the dopamine level to fall back to the baseline. Thus, extra-cellular dopamine governs the response vigor, with an increase in dopamine resulting in a more vigorous response. This paper makes two primary contributions. Firstly, we present an abstract mathematical model based on the above hypothesis. Our mathematical model is able to provide a simple explanation for a number of behavioral findings. Another contribution of this paper is the development of a neurocomputational Leabra model of dopamine and acetylcholine activity in the basal ganglia to incorporate hunger and satiation. The experimental results obtained from this neural model are also largely in agreement with behavioral findings. (shrink)

A large amount of data is maintained in every Social networking sites.The total data constantly gathered on these sites make it difficult for methods like use of field agents, clipping services and ad-hoc research to maintain social media data. This paper discusses the previous research on sentiment analysis.

Social media sites offer a huge data about our everyday life, thoughts, feelings and reflecting what the users want and like. Since user behavior on OSNS is a mirror image of actions in the real world, scholars have to investigate the use SM to prediction, making forecasts about our daily life. This paper provide an overview of different commonly used social media and application of their data analysis.

This volume is based on innovative ideas coming from different Indic philosophies and how they can enrich the theory and methods in religious studies.

Human perception has long been a critical subject of design thinking. While various studies have stressed the link between thinking and acting, particularly in spatial experience, the term “design thinking” seems to disconnect conceptual thinking from physical expression or process. Spatial perception is multimodal and fundamentally bound to the body that is not a mere receptor of sensory stimuli but an active agent engaged with the perceivable environment. The body apprehends the experience in which one’s kinesthetic engagement and knowledge play (...) an essential role. Although design disciplines have integrated the abstract, metaphoric, and visual aspects of the body and its movement into conceptual thinking, studies have pointed out that design disciplines have emphasized visuality above the other sensory domains and heavily engaged with the perception of visual configurations, relying on the Gestalt principles. Gestalt psychology must be valued for its attention to a whole. However, the theories of design elements and principles over-empathizing such visuality posit the aesthetics of design mainly as visual value and understate other sensorial and perceptual aspects. Although the visual approach may provide a practical means to represent and communicate ideas, a design process heavily driven by visuality can exhibit weaknesses undermining certain aspects of spatial experience despite the complexity. Grounded in Merleau-Ponty’s notion of multisensory perception, this article discusses the relationship between body awareness and spatial perception and its implication for design disciplines concerning built environments. Special attention is given to the concepts of kinesthetic and synesthetic phenomena known as multisensory and cross-sensory, respectively. This discussion integrates the corporeal and spatiotemporal realms of human experience into the discourse of kinesthetic and synesthetic perceptions. Based on the conceptual, theoretical, and precedent analyses, this article proposes three models for design thinking: Synesthetic Translation, Kinesthetic Resonance, and Kinesthetic Engagement. To discuss the concepts rooted in action-based perception and embodied cognition, this study borrows the neurological interpretation of haptic perception, interoception, and proprioception of space. This article suggests how consideration of the kinesthetic or synesthetic body can deepen and challenge the existing models of the perceptual aspects of environmental psychology adopted in design disciplines.

Differential scanning calorimetry (DSC) has been employed to investigate the glass transition activation energy E g, thermal stability and glass-forming ability (GFA) of Se90In10− x Sb x (x = 0, 2, 4, 6, 8, 10) chalcogenide glasses. DSC runs were performed at six different heating rates. Well-defined endothermic and exothermic peaks were obtained at glass transition and crystallization temperature. The dependence of glass transition temperature T g on heating rate (α), as well as composition of Sb, has been studied. From (...) the dependence of glass transition temperature on heating rate, the E g has been calculated on the basis of the Kissinger [Anal. Chem. 29 (1957) p.1702] and Moynihan [J. Phys. Chem. 78 (1974) p.267] models. Thermal stability has been monitored through the calculation of temperature differences T c–T g, the stability parameter S, and the enthalpy released during crystallization H c. The GFA has been investigated on the basis of the Hruby parameter H r, which is strong indicator of GFA. Results for GFA are in good agreement with fragility index F i calculations, indicating that Se90In6Sb4 is an excellent glass-former. (shrink)

Lochlann Jain's debut non-fiction graphic novel, Things That Art, playfully interrogates the order of things. Toying with the relationship between words and images, Jain's whimsical compositions may seem straightforward. Upon closer inspection, however, the drawings reveal profound and startling paradoxes at the heart of how we make sense of the world. Commentaries by architect and theorist Maria McVarish, poet and naturalist Elizabeth Bradfield, musician and English Professor Drew Daniel, and the author offer further insight into the drawings in (...) this collection. A captivating look at the fundamental absurdities of everyday communication, Things that Art jolts us toward new forms of collation and collaboration. (shrink)

According to Arti Dhand, it can be argued that all Indian ethics have been primarily virtue ethics. Many have indeed jumped on the virtue bandwagon, providing prima facie interpretations of Hindu, Jain, and Buddhist canons in virtue terms. Others have expressed firm skepticism, claiming that virtues are not proven to be grounded in the nature of things and that, ultimately, the appeal to virtue might just well be a mere façon de parler. In this paper, we aim to advance (...) the discussion of Indian virtue ethics. Our intent is not to provide a catch-all interpretation of the different Indian schools. Our goal is, more modestly, to offer a theory of virtues in Indian philosophies, as a framework for theorists and interpreters who see these diverse traditions as amenable to systematic virtue analysis. Our theory grounds virtues in the reality of genuine moral dispositions and in a system of beliefs where morality is understood as transformative in nature. (shrink)

Numerous high-profile ethics scandals, rising inequality, and the detrimental effects of climate change dramatically underscore the need for business schools to instill a commitment to social purpose in their students. At the same time, the rising financial burden of education, increasing competition in the education space, and overreliance on graduates’ financial success as the accepted metric of quality have reinforced an instrumentalist climate. These conflicting aims between social and financial purpose have created an existential crisis for business education. To resolve (...) this impasse, we draw on the concept of moral self-awareness to offer a system-theoretical strategy for crowding-in a culture of ethics within business schools. We argue that to do so, business schools will need to (1) reframe the purpose of business, (2) reframe the meaning of professional success, and (3) reframe the ethos of business education itself.

As Acharya Vidyanand writes in the Foreword of Samayasara, it is the ultimate conscious reality. The enlightened soul has infinite glory. It has the innate ability to demolish the power of karmas, both auspicious as well as inauspicious, which constitute the cycle of births and deaths, and are an obstacle in the path of liberation of the soul. Samayasara is an essential reading for anyone who wishes to lead a purposeful and contented life. It provides irrefutable and lasting solutions to (...) all our problems, concerning worldly ways as well as spiritual curiosities and misgivings. (shrink)

Nationwide, almost 11% of women abuse drugs during their pregnancy. In some communities, these numbers are as high as 25–30%. Drug abuse is not limited to the poor or to African Americans, but is seen among affluent and white Americans as well. It is widespread, irrespective of race or social class. Annually, nearly 375,000 infants are exposed to drugs in America. Because of the terrible suffering caused by these births, and the conflicts caregivers experience in the treatment of these infants, (...) Trollope's quote is very apropos. Although caregivers have good motives in trying to rescue these babies and helping place them in a nurturing environment, despair about this objective is always close to the surface. (shrink)

We appreciated the important commentary provided by Michelle Oberman on our paper, “Discontinuing Life Support in an Infant of a Drug-Addicted Mother: Whose Decision Is It?” . For the most part we agree with Oberman's analysis of the issues, but there are seven points of variance, either of conception, emphasis, or accuracy. We wish to clarify these and welcome the chance her commentary provided to offer aspects of the social situation surrounding the case we presented.

Mental health-related data generated by app users during the routine use of Consumer Mental Health Apps (CMHAs) are being increasingly leveraged for research and product improvement studies. However, it remains unclear which ethical safeguards and practices should be implemented by researchers and app developers to protect users during these studies, and concerns have been raised over their current implementation in CMHAs. To better understand which ethical safeguards and practices are implemented, why and how, 17 app developers and researchers were interviewed (...) who had been involved in using CMHA data for studies. Interviewees discussed the impact on stakeholder interests, sufficiency thresholds and procedural alterations of informed consent, data protection, gathering app user perspectives and representing users in app design and study conduct, and ensuring adequate support. Although the reasoning behind how and why these ethical safeguards and practices should be implemented showed considerable variability and several gaps, interviewees converged on various general lines of reasoning. This allowed for the development of a coherent and nuanced account that could prove useful for future CMHA studies and which could stimulate further normative investigation of the role of ethical safeguards and practices in these studies.

Most theories of learning consider inferring a function f from either observations about f or, questions about f. We consider a scenario whereby the learner observes f and asks queries to some set A. If I is a notion of learning then I[A] is the set of concept classes I-learnable by an inductive inference machine with oracle A. A and B are I-equivalent if I[A] = I[B]. The equivalence classes induced are the degrees of inferability. We prove several results about (...) when these degrees are trivial, and when the degrees are omniscient. (shrink)

We investigate dependence of recursively enumerable graphs on the equality relation given by a specific r.e. equivalence relation on ω. In particular we compare r.e. equivalence relations in terms of graphs they permit to represent. This defines partially ordered sets that depend on classes of graphs under consideration. We investigate some algebraic properties of these partially ordered sets. For instance, we show that some of these partial ordered sets possess atoms, minimal and maximal elements. We also fully describe the isomorphism (...) types of some of these partial orders. (shrink)

Purpose Along with their immense benefit, online channels of communication and information-sharing also present a myriad set of challenges. The unauthorized downloading and sharing of copyrighted content such as music and movies is one such issue. This study aims to examine the factors related to the unauthorized downloading of content amongst young internet users in an emerging market. Design/methodology/approach An online structured questionnaire was used to collect primary data from 219 internet users between 17 and 24 years of age. The (...) partial least squares structural equation modelling was used to analyse the primary data. Findings The study findings report that monetary savings and social influence are the main drivers underlying the propensity to engage in unauthorized downloading amongst young adults. Perceptions of harm caused to artists and producers appear to be a deterrent. Though the respondents perceive the quality of content downloaded from unauthorized sites to be less than desirable, and there is also a higher perceived threat from viruses, this does not appear to deter unauthorized downloading behaviour amongst this segment of consumers. Research limitations/implications Combating unauthorized downloading and other forms of questionable online behaviours is a challenge for multiple stakeholders. Consumption of unauthorized digital content is examined in the context of online consumers whose demographic profile is often associated with this category of questionable behaviour. The study adds to the extant understanding of the aetiology of what are often considered online unethical and illegal behaviours and makes both practical and theoretical contributions to the subject field. Originality/value The study examines an important aspect of rapidly evolving internet technologies. The internet provides a veil to individuals engaging in unethical online activities. Despite the existence of laws declaring these activities to be illegal, instances of copyright violations of music and movies abound. The insights regarding the drivers and deterrents of a form of online unauthorized activity are used to present a set of strategies aimed at addressing such behaviours. (shrink)

Perceived supervisor support is widely studied in terms of its positive outcomes. This paper, in contrast, investigates employees’ unethical pro-supervisor behavior as a negative consequence of perceived supervisor support. Drawing upon the multifoci approach of social exchange theory and the reciprocity principle, we hypothesized that perceived supervisor support can engender unethical pro-supervisor behavior via employees’ feelings of reciprocity towards the supervisor. Building on the instrumental reasons that underlie social exchanges, we further hypothesized that this mediation relationship is stronger for employees (...) high in Machiavellianism. We collected data for three experimental studies from full-time MBA students of a European business school and from U.S. working professionals, and the results provided consistent support for our proposed model. Taken together, the current study highlights the “dark side” of perceived supervisor support, in that it can lead to unethical behavior and that this effect can be accentuated by employees’ Machiavellianism.

Academic dishonesty among students at colleges and universities has been a serious problem all over the world. Due to advances in information and communication technologies, particularly the Internet, the problem has become more severe in the past two decades. This is especially serious among undergraduate students. Very little research has been done in this field in Botswana and Zambia. This study was an attempt in this direction. This paper presents the findings of the study carried out with second year students (...) at the University of Botswana and the University of Zambia. The main objectives of the research were to investigate students' attitudes toward academic dishonesty, frequency of cheating, cheating methods used, and motives for cheating in a local university context. To pursue the study a questionnaire survey was used. The results revealed that students had a high knowledge of various forms of academic dishonesty; and were of the opinion that academic dishonesty devalues academic qualifications. Academic dishonesty was widely practiced; yet, it was not adequately dealt with. The paper recommends that various stakeholders should collaborate to continually educate and discourage students from indulging in academic dishonesty. (shrink)

This paper considers reductions between types of numberings; these reductions preserve the Rogers Semilattice of the numberings reduced and also preserve the number of minimal and positive degrees in their semilattice. It is shown how to use these reductions to simplify some constructions of specific semilattices. Furthermore, it is shown that for the basic types of numberings, one can reduce the left-r.e. numberings to the r.e. numberings and the k-r.e. numberings to the k+1-r.e. numberings; all further reductions are obtained by (...) concatenating these reductions.
