AbstractPothos & Busemeyer (P&B) argue convincingly that quantum probability offers an improvement over classical Bayesian probability in modeling the empirical data of cognitive science. However, a weakness related to restrictions on the dimensionality of incompatible physical observables flows from the authors' “agnosticism” regarding quantum processes in neural substrates underlying cognition. Addressing this problem will require either future research findings validating quantum neurophysics or theoretical expansion of the uncertainty principle as a new, neurocognitively contextualized, “local” symmetry.

AbstractClassical (Bayesian) probability (CP) theory has led to an influential research tradition for modeling cognitive processes. Cognitive scientists have been trained to work with CP principles for so long that it is hard even to imagine alternative ways to formalize probabilities. However, in physics, quantum probability (QP) theory has been the dominant probabilistic approach for nearly 100 years. Could QP theory provide us with any advantages in cognitive modeling as well? Note first that both CP and QP theory share the fundamental assumption that it is possible to model cognition on the basis of formal, probabilistic principles. But why consider a QP approach? The answers are that (1) there are many well-established empirical findings (e.g., from the influential Tversky, Kahneman research tradition) that are hard to reconcile with CP principles; and (2) these same findings have natural and straightforward explanations with quantum principles. In QP theory, probabilistic assessment is often strongly context- and order-dependent, individual states can be superposition states (that are impossible to associate with specific values), and composite systems can be entangled (they cannot be decomposed into their subsystems). All these characteristics appear perplexing from a classical perspective. However, our thesis is that they provide a more accurate and powerful account of certain cognitive processes. We first introduce QP theory and illustrate its application with psychological examples. We then review empirical findings that motivate the use of quantum theory in cognitive theory, but also discuss ways in which QP and CP theories converge. Finally, we consider the implications of a QP theory approach to cognition for human rationality.

A modern scientific development cannot be imagined without the use of a statistical methodology, which is based on the empirical research.  So, it is necessary for social and economic development of the whole society.  The level of young scientists’ ability to conduct the empirical research can be considered as a quality factor of their future research activities.The preliminary analysis of young Kazakh scientists’ works showed very little applicability of systems and technology use for the processing of statistical data.  The objective is to determine the main critical points in the empirical research that cause the most trouble in the applicability of the statistical research methods, systems and data processing technologies for the writing of Undergraduate level final qualifying works.The analysis of existing empirical data processing technologies and their level of accessibility to university students was made in order to address this problem. The investigation was conducted among Undergraduate courses across 56 departments in different directions, the main reasons were identified and the analysis of possible ways to overcome the causes was made.  An example of a particular case decision and simplification of the empirical data processing is also presented in the research findings.

Despite widespread suspicion to the contrary, secular living can and does serve as an adequate, or even excellent, context for moral development. In this chapter, the authors present the contours of contemporary anti-atheist prejudice, with an emphasis on the United States. Next, they explore the empirical data showing that individual atheists and highly secularized societies, such as Sweden and Denmark, are often quite moral, which serves to counter and debunk anti-atheist prejudice. Then, the authors move to a philosophical discussion centering around secular morality itself, outlining general merits of atheistic morality specifically while simultaneously pointing out various problematic assumptions of theistic morality. Finally, the authors conclude and make recommendations for future research.

Abstract Nanofluid is a colloidal mixture consisting of nano-sized particles dispersed in a liquid medium. It improves heat transfer properties and promotes high energy efficiency in a wide spectrum of engineering applications. In recent years, particularly in the automotive industry, the addition of nanofluid in diesel/biodiesel as an additive for ICE has become an attractive approach to promote enhanced combustion efficiency and emission reduction due to their superior thermophysical properties. Many researchers have previously demonstrated that the addition of nanoparticles in diesel/biodiesel fuel improved the overall engine combustion characteristics. As a whole, this study aims to summarize the recent research findings related to the effect of nanoparticles on the fuel properties and engine combustion efficiency. Furthermore, different types of additive blended with varying fuel properties are also compared and discussed. Lastly, the advantages and prospects of using nanofluid as an additive fuel are summarized for future research opportunities.

Abstract Background Evidence suggests that an overlap exists between the neurobiology of psychotic disorders and the effects of cannabinoids on neurocognitive and neurochemical substrates involved in reward processing. Aims We investigate whether the psychotomimetic effects of delta-9-tetrahydrocannabinol (THC) and the antipsychotic potential of cannabidiol (CBD) are underpinned by their effects on the reward system and dopamine. Methods This narrative review focuses on the overlap between altered dopamine signalling and reward processing induced by cannabinoids, pre-clinically and in humans. A systematic search was conducted of acute cannabinoid drug-challenge studies using neuroimaging in healthy subjects and those with psychosis Results There is evidence of increased striatal presynaptic dopamine synthesis and release in psychosis, as well as abnormal engagement of the striatum during reward processing. Although, acute THC challenges have elicited a modest effect on striatal dopamine, cannabis users generally indicate impaired presynaptic dopaminergic function. Functional MRI studies have identified that a single dose of THC may modulate regions involved in reward and salience processing such as the striatum, midbrain, insular, and anterior cingulate, with some effects correlating with the severity of THC-induced psychotic symptoms. CBD may modulate brain regions involved in reward/salience processing in an opposite direction to that of THC. Conclusions There is evidence to suggest modulation of reward processing and its neural substrates by THC and CBD. Whether such effects underlie the psychotomimetic/antipsychotic effects of these cannabinoids remains unclear. Future research should address these unanswered questions to understand the relationship between endocannabinoid dysfunction, reward processing abnormalities, and psychosis.

Abstract The past few decades have seen a plethora of interest in heritage studies in international law, as the legitimization of cultural heritage is a significant aspect of protecting the legacy of humanity’s collective memory, which is fully reflected in a series of international instruments on culture. This paper examines the meaning-making process of UNESCO legal documents on cultural heritage from a sociosemiotic perspective. The data for the corpus-based study were analyzed quantitatively and qualitatively by applying the securitization theory to heritage studies. Research findings reveal three significant shifts in cultural heritage, i.e., from property to heritage, from tangible to intangible, and from material-centered to human-centered, which embodies the harmonious coexistence of humanity and nature, a philosophical idea embedded in traditional Chinese culture. As noted, terms targeting cultural heritage in UNESCO international instruments are the sign vehicle, generally mediated and shaped by social values, cultural beliefs, and conventional wisdom, etc. as a part of the interpretant, making different categories of heritage meaningful and interpretable. Characterized by temporality and spatiality, cultural heritage is subject to multiple interpretations. The meaning-making of international instruments for consideration is a sociosemiotic operation that can be construed through contextual factors and a process of social negotiation. This paper argues that a sociosemiotic approach to heritage studies is conducive to explicating the construction and deconstruction of heritage as discursive practices while offering some implications for future research.

Background: Impact in research encompasses health, economic, and cultural benefits beyond adding to the knowledge base. Funders are under immense pressure to be accountable for the paybacks from funded research.Aims and objectives: The aim of this study was to look into the impact of funded biomedical research between the years 2005 and 2015 in Malaysia from the aspects of knowledge production, research targeting and capacity building, as well as health system policy and decision making.Methods: This study employed a convergent parallel mixed-methods research design. Biomedical projects related to breast cancer, coronary heart disease, and dengue, funded by the Ministry of Health (MOH), Ministry of Higher Education (MOHE), and Ministry of Science, Technology, and Innovation (MOSTI) between the years 2005 and 2015, were included.Findings: From the questionnaire responses (n=58), on average each funded project managed to produce two outputs and one higher degree student. More than half (61.4%) of the funded projects led to subsequent future research. However, low citations in systematic reviews (10.3%), health policies (6.9%), and clinical practice guidelines (5.2%) were reported. In-depth interviews with the key opinion leaders also saw that most of the local research findings were found to be irrelevant to be adopted into policies by the policymakers.Discussion and conclusions: Paybacks on knowledge production as well as research targeting and capacity building had been achieved, but impact on health system policy and decision making had not been well attained, due to the lack of relevant research findings needed by the policymakers.<br />Key messages<br /><ul><li>Payback on knowledge production was achieved, as there had been a lot of new knowledge generated as captured in academic publications, conference proceedings, policy briefs, technical reports, and research highlights, which is important to advance the frontiers of knowledge.</li><br /><li>Payback on research targeting was achieved, with the current research leading to future study with identification of the knowledge gap and generation of new ideas for new research.</li><br /><li>Payback on capacity building was achieved with the training of researchers, building up research capacity and competencies, production of MSc and PhD graduates, promotion of lecturers, and development of new partnerships and networks.</li><br /><li>Impact on health system policy and decision making was not well attained. There had been a lack of relevant research data and findings being incorporated into policymaking, due to the basic and fundamental nature of most of the funded biomedical research in Malaysia.</li></ul>
