The theory of rough sets starts with the notion of an approximation space , which is a pair ( U , R ), U being the domain of discourse, and R an equivalence relation on U . R is taken to represent the knowledge base of an agent, and the induced partition reflects a granularity of U that is the result of a lack of complete information about the objects in U . The focus then is on approximations of concepts (...) on the domain, in the context of the granularity. The present article studies the theory in the situation where information is obtained from different sources. The notion of approximation space is extended to define a multiple-source approximation system with distributed knowledge base , which is a tuple , where N is a set of sources and P ranges over all finite subsets of N . Each R P is an equivalence relation on U satisfying some additional conditions, representing the knowledge base of the group P of sources. Thus each finite group of sources and hence individual source perceives the same domain differently (depending on what information the group/individual source has about the domain), and the same concept may then have approximations that differ with the groups. In order to express the notions and properties related with rough set theory in this multiple-source situation, a quantified modal logic LMSAS D is proposed. In LMSAS D , quantification ranges over modalities, making it different from modal predicate logic and modal logic with propositional quantifiers. Some fragments of LMSAS D are discussed and it is shown that the modal system KTB is embedded in LMSAS D . The epistemic logic is also embedded in LMSAS D , and cannot replace the latter to serve our purpose. The relationship of LMSAS D with first and second-order logics is presented. Issues of expressibility, axiomatization and decidability are addressed. (shrink)

The food security of more than half of the world’s population depends on rice production which is one of the key objectives of precision agriculture. The traditional rice almanac used astronomical and climate factors to estimate yield response. However, this research integrated meteorological, agro-chemical, and soil physiographic factors for yield response prediction. Besides, the impact of those factors on the production of three major rice ecotypes has also been studied in this research. Moreover, this study found a different set of (...) those factors with respect to the yield response of different rice ecotypes. Machine learning algorithms named Extreme Gradient Boosting and Support Vector Regression have been used for predicting the yield response. The SVR shows better results than XGBoost for predicting the yield of the Aus rice ecotype, whereas XGBoost performs better for forecasting the yield of the Aman and Boro rice ecotypes. The result shows that the root mean squared error of three different ecotypes are in between 9.38% and 24.37% and that of R-squared values are between 89.74% and 99.13% on two different machine learning algorithms. Moreover, the explainability of the models is also shown in this study with the help of the explainable artificial intelligence model called Local Interpretable Model-Agnostic Explanations. (shrink)

Background. Imposter syndrome, associated with self-doubt and fear despite clear accomplishments and competencies, is frequently detected in medical students and has a negative impact on their well-being. This study aimed to predict the students’ IS using the machine learning ensemble approach. Methods. This study was a cross-sectional design among medical students in Bangladesh. Data were collected from February to July 2020 through snowball sampling technique across medical colleges in Bangladesh. In this study, we employed three different machine learning techniques such (...) as neural network, random forest, and ensemble learning to compare the accuracy of prediction of the IS. Results. In total, 500 students completed the questionnaire. We used the YIS scale to determine the presence of IS among medical students. The ensemble model has the highest accuracy of this predictive model, with 96.4%, while the individual accuracy of random forest and neural network is 93.5% and 96.3%, respectively. We used different performance matrices to compare the results of the models. Finally, we compared feature importance scores between neural network and random forest model. The top feature of the neural network model is Y7, and the top feature of the random forest model is Y2, which is second among the top features of the neural network model. Conclusions. Imposter syndrome is an emerging mental illness in Bangladesh and requires the immediate attention of researchers. For instance, in order to reduce the impact of IS, identifying key factors responsible for IS is an important step. Machine learning methods can be employed to identify the potential sources responsible for IS. Similarly, determining how each factor contributes to the IS condition among medical students could be a potential future direction. (shrink)

Vacuolar ATPases (V‐ATPases, V1Vo‐ATPases) are rotary motor proton pumps that acidify intracellular compartments, and, when localized to the plasma membrane, the extracellular space. V‐ATPase is regulated by a unique process referred to as reversible disassembly, wherein V1‐ATPase disengages from Vo proton channel in response to diverse environmental signals. Whereas the disassembly step of this process is ATP dependent, the (re)assembly step is not, but requires the action of a heterotrimeric chaperone referred to as the RAVE complex. Recently, an alternative pathway (...) of holoenzyme disassembly was discovered that involves binding of Oxidation Resistance 1 (Oxr1p), a poorly characterized protein implicated in oxidative stress response. Unlike conventional reversible disassembly, which depends on enzyme activity, Oxr1p induced dissociation can occur in absence of ATP. Yeast Oxr1p belongs to the family of TLDc domain containing proteins that are conserved from yeast to mammals, and have been implicated in V‐ATPase function in a variety of tissues. This brief perspective summarizes what we know about the molecular mechanisms governing both reversible (ATP dependent) and Oxr1p driven (ATP independent) V‐ATPase dissociation into autoinhibited V1 and Vo subcomplexes.

The competition in higher education has increased, while lecturers are involved in multiple assignments that include teaching, research and publication, consultancy, and community services. The demanding nature of academia leads to excessive work load and stress among academicians in higher education. Notably, offering the right motivational mix could lead to job satisfaction and performance. The current study aims to demonstrate the effects of extrinsic and intrinsic motivational factors influencing job satisfaction and job performance among academicians working in Malaysian private higher (...) educational institutions. Cross-sectional data were collected from the Malaysian PHEIs and the randomly selected 343 samples. The data analysis was performed with the dual analysis of partial least square structural equation modeling and artificial neural network analysis. As a result, it was found that financial rewards, promotion, performance appraisal, classroom environment, and code of conduct significantly predicted job satisfaction. The code of conduct, autonomy, and self-efficacy strongly influenced job performance. The relationship between job satisfaction and job performance was highly moderated by self-efficacy. It was suggested from the ANN analysis that the three prominent factors influencing job satisfaction are financial rewards, performance appraisal, and code of conduct. The analysis supported three significant factors influencing job performance: self-efficacy, performance appraisal, and code of conduct. The management of PHEIs should build the correct policies to transform job satisfaction into job performance. Self-efficacy plays an essential role in activating job performance. Other significant motivating factors that promote job satisfaction and performance, such as emotional intelligence, mindfulness, and other personal traits, should be included in future studies. In addition, future research could use a mixed-method or multi-respondent approach to investigate the important variables and their impact on lecturers’ job satisfaction and performance. (shrink)

Clinical responses to dopamine replacement therapy for individuals with Parkinson’s disease are often difficult to predict. We characterized changes in MDS-UPDRS motor factor scores resulting from a short-duration L-Dopa response, and investigated how the inter-subject clinical differences could be predicted from motor cortical magnetoencephalography. MDS-UPDRS motor factor scores and resting-state MEG recordings were collected during SDR from twenty individuals with a PD diagnosis. We used a novel subject-specific strategy based on linear support vector machines to quantify motor cortical oscillatory frequency (...) profiles that best predicted medication state. Motor cortical profiles differed substantially across individuals and showed consistency across multiple data folds. There was a linear relationship between classification accuracy and SDR of lower limb bradykinesia, although this relationship did not persist after multiple comparison correction, suggesting that combinations of spectral power features alone are insufficient to predict clinical state. Factor score analysis of therapeutic response and novel subject-specific machine learning approaches based on subject-specific neuroimaging provide tools to predict outcomes of therapies for PD.

Within the Ideological Surround Model of the social sciences and religion, so-called “universal” perspectives within the psychology of religion can dialogically clarify and be clarified by the “particular” elements of Muslim commitment. This study developed new scales for operationalizing the experience and behavior of Pakistani Muslims during Ramadan. In a sample of university students, one set of experiential factors apparently facilitated, whereas another interfered with the practices of Ramadan. Intrinsic and Extrinsic Personal Religious Orientations correlated with greater and the Extrinsic (...) Social motivation with lower levels of involvement in Ramadan. Relative to these religious orientation measures, Ramadan experience scales displayed incremental validity by explaining additional variance in Ramadan behavior. Women proved to be more religious than men. At the most general level, these data further supported the dialogic assumptions of the Ideological Surround Model of research in the psychology of religion. (shrink)

Organ transplantation from living related donors in Bangladesh first began in October 1982, and became commonplace in 1988. Cornea transplantation from posthumous donors began in 1984 and living related liver and bone marrow donor transplantation began in 2010 and 2014 respectively. The Human Organ Transplantation Act officially came into effect in Bangladesh on 13th April 1999, allowing organ donation from both brain-dead and related living donors for transplantation. Before the legislation, religious leaders issued fatwa, or religious rulings, in favor of (...) organ transplantation. The Act was amended by the Parliament on 8th January, 2018 with the changes coming into effect shortly afterwards on 28th January. However, aside from a few posthumous corneal donations, transplantation of vital organs, such as the kidney, liver, heart, pancreas, and other body parts or organs from deceased donors, has remained absent in Bangladesh. The major question addressed in this article is why the transplantation of vital organs from deceased donors is absent in Bangladesh. In addition to the collection of secondary documents, interviews were conducted with senior transplant physicians, patients and their relatives, and the public, to learn about posthumous organ donation for transplantation. Interviews were also conducted with a medical student and two grief counselors to understand the process of counseling the families and obtaining consent to obtain posthumous cornea donations from brain-dead patients. An interview was conducted with a professional anatomist to understand the processes behind body donation for the purposes of medical study and research. Their narrative reveals that transplant physicians may be reticent to declare brain death as the stipulations of the 1999 act were unclear and vague. This study finds that Bangladeshis have strong family ties and experience anxiety around permitting separating body parts of dead relatives for organ donation for transplantation, or donating the dead body for medical study and research purposes. Posthumous organ donation for transplantation is commonly viewed as a wrong deed from a religious point of view. Religious scholars who have been consulted by the government have approved posthumous organ donation for transplantation on the grounds of necessity to save lives even though violating the human body is generally forbidden in Islam. An assessment of the dynamics of biomedicine, religion and culture leads to the conclusion that barriers to posthumous organ donation for transplantation that are perceived to be religious may actually stem from cultural attitudes. The interplay of faith, belief, religion, social norms, rituals and wider cultural attitudes with biomedicine and posthumous organ donation and transplantation is very complex. Although overcoming the barriers to organ donation for transplantation is challenging, initiation of transplantation of vital organs from deceased donors is necessary within Bangladesh. This will ensure improved healthcare outcomes, prevent poor people from being coerced into selling their organs to rich recipients, and protect the solidarity and progeny of Bangladeshi families.

Background Advocates for a regulated system to facilitate kidney donation between unrelated donor-recipient pairs argue that monetary compensation encourages people to donate vital organs that save the lives of patients with end-stage organ failure. Scholars support compensating donors as a form of reciprocity. This study aims to assess the compensation system for the unrelated kidney donation program in the Islamic Republic of Iran, with a particular focus on the implications of Islam on organ donation and organ sales. Methods This study (...) reviews secondary documents for philosophical argumentation and ethical analysis of human organ donation and sale for transplantation. Results and discussion According to Islamic law, organ donation is an act of _sadaqatul jariyah,_ and individuals are permitted to donate organs with the intention of saving lives. The commercialization of humans as organ sellers and buyers is contrary to the Islamic legal maxim _eethaar_, undermining donors of ‘selfless’ or ‘altruistic’ motivations. Such an act should be considered immoral, and the practice should not be introduced into other countries for the sake of protecting human dignity, integrity, solidarity, and respect. I, therefore, argue that Iran’s unrelated kidney donation program not only disregards the position of the Islamic religion with respect to the provision or receipt of monetary benefits for human kidneys for transplantation but that it also misinterprets the Islamic legal proscription of the sale of human organs. I also argue that the implementation of Iran’s unrelated kidney donor transplantation program is unethical and immoral in that potential donors and recipients engage in a bargaining process akin to that which sellers and buyers regularly face in regulated commodity exchange markets. Conversely, I suggest that a modest fixed monetary remuneration as a gift be provided to a donor as a reward for their altruistic organ donation, which is permissible by Islamic scholars. This may remove the need to bargain for increased or decreased values of payment in exchange for the organ, as well as the transactional nature of ‘buyer and seller’, ensuring the philosophy of ‘donor and recipient’ is maintained. Conclusions Offering a fixed modest monetary incentive to organ donors would serve to increase organ supply while protecting donors’ health and reducing human suffering without legalizing the human organ trade.

Bangladesh, a Muslim-majority country, has a national organ donation law that was passed in 1999 and revised in 2018. The law allows living-related and brain-dead donor organ transplantation. There are no legal barriers to these two types of organ donations, but there is no legislation providing necessary costs and incentive measures associated with successful organ transplants. However, many governments across the globe provide different types of incentives for motivating living donors and families of deceased donors. This study assesses the merits (...) and demerits of incentive measures already in use around the world and proposes ethical measures that can promote organ donation in Bangladesh. The primary focus of this paper is to present an ethical analysis of the comparison of incentive measures on organ donation between Bangladesh and the Islamic Republic of Iran as two Muslim countries that operate organ donation for transplantation practices according to Islamic principles. In this paper, I mainly argue that providing a fixed bare minimum financial incentive measure to distantly related living donors and families of deceased donors will encourage Bangladeshis to donate organs in a manner that is ethically justifiable, morally permissible, and socio-economically appropriate. The government of Bangladesh should revise the existing biomedical law to include a provision related to incentive measures and set a strict policy to properly regulate these measures as key stewardship that can ethically promote organ donation for transplantation.

The Infectious Diseases Act entered into force officially on 14 November 2018 in Bangladesh. The Act is designed to raise awareness of, prevent, control, and eradicate infectious or communicable diseases to address public health emergencies and reduce health risks. A novel coronavirus disease was first identified in Bangladesh on 8 March 2020, and the Ministry of Health and Family Welfare issued a gazette on 23 March, listing COVID-19 as an infectious disease and addressing COVID-19 as a public health emergency. The (...) gazette empowers the government to monitor the spread of infection. Despite there being an infrastructure of research ethics committees in almost all hospitals in Bangladesh, a lack of such committees in the clinical setting often forces healthcare professionals to allocate scarce healthcare resources to the task. These personnel are often either influenced by materialistic matters or guided by the emergency policies, without reaching a consensus on how to allocate scarce resources in times of need, especially in the time of the COVID-19 pandemic. Ethical dilemmas often arise when a number of patients with COVID-19, especially in poor and middle-class areas, are denied care while elites are prioritized to receive such scarce resources. Resource allocation in healthcare during the COVID-19 pandemic in Bangladesh appears to be unethical and in direct conflict with the biomedical principles of non-maleficence and procedural justice. The findings of this study suggest that the Act needs substantive changes in the stipulation of policy directing hospitals in the provision of resource allocation framework. Furthermore, parliament should produce guidance outlining how to successfully implement the law with the aim of protecting public health in times of emergency, especially the COVID-19 pandemic.

The Human Organ Transplantation Act came into officially force in Bangladesh on April 13, 1999, allowing organ donations from both living and brain-dead donors. The Act was amended by the Parliament on January 8, 2018, with the changes coming into effect shortly afterwards on January 28. The Act was revised to extend a living donor pool from close relatives to include certain other relatives such as grandparents, grandchildren, and first cousins. The Act was also revised to allow individuals to prioritize (...) family members in receiving their organs after their death. The aim of this paper is not to carry out an ethical analysis of the Act as a whole but only to focus on aspects relating to priority access for family members to organs. Despite Islam encouraging Muslims to be sympathetic, and to save the life of any member of humankind, saving the life of a relative through organ donation is even more highly valued. The collective and extended structure of the family impacts on the provisions of the Act that only allows Bangladeshis to legally donate their organs to save the lives of relatives and allows individuals to prioritize family members. Recent progress in the practice of organ transplantation raises a number of ethical dilemmas around the allocation of available organs in the context of organ scarcity. A key purpose of introducing incentive into the system of organ allocation is to increase the number of donations from living relatives and initiation of vital organ donations from brain-dead donors. However, allocation criteria based on a living organ donation incentive system would appear to be unethical because there is no provision in the Act with regard to financial compensation for a distant relative donor’s post-operative care in the absence of healthcare coverage. Receiving organs from a distant relative without giving financial compensation for post-operative care places them in a grave health condition and violates the biomedical principle of non-maleficence. An incentive system around brain-dead donors would appear to be ethical as the amended Act allows individuals to prioritize relatives in receiving their organs after death. This provision is intended to initiate the transplantation of vital organs from brain-dead donors as families might bear the cost of keeping the organs alive for transplantation. Regular reassessment of the impact of the Act is necessary to maximize the donation rate of transplantable organs using ethical means. (shrink)

The New Towns Movement began in England and later spread world-wide in response to the increasing concern felt at the deterioration of the quality of life in the large cities under the impact of industrialization. The New Towns, it was felt, would combine the advantages of life in the country with that of life in the city. They would be small communities of between 30.000 and 60.000 inhabitants. Their principal characteristics were to be a balanced economy and a well-defined pattern (...) of industrial, commercial and residential zones. (shrink)

This study aims to investigate the impact of stakeholders’ views on the practices of green innovation, consequent effect on environmental and organizational performance, and moderating influence of innovation orientation. A quantitative method was employed for the sample size of 515 responses. To accumulate the data from the respondents, convenient random sampling was used. Data were collected from manufacturing and services firms through a field survey by using a closed-ended questionnaire based in the Punjab province of Pakistan. The analysis was done (...) using the structural equation model of the partial least square analysis method. Our findings proved a positive and significant link between stakeholders’ views on GI practices. A significant association has been found between GI practices and environmental and OP. The moderating effect was found to be negative but statistically significant. This research offers numerous contributions and provides decision-making insinuations. (shrink)

There was also an association between culture and religiosity. The MANOVA results also showed that culture and religiosity have an effect on perceptions of business ethics. (shrink)

In 1999, the Bangladesh government introduced the Human Organ Transplantation Act allowing organ transplants from both brain-dead and living-related donors. This Act approved organ donation within family networks, which included immediate family members such as parents, adult children, siblings, uncles, aunts, and spouses. Subsequently, in January 2018, the government amended the 1999 Act to include certain distant relatives, such as grandparents, grandchildren, and first cousins, in the donor lists, addressing the scarcity of donors. Nobody, without these relatives, is legally permitted (...) to donate organs for transplantation in Bangladesh. The focus of this study was to investigate who should donate organs for transplantation in Bangladesh. The ethnographic fieldwork revealed that potential donors are not always available to immediate family members, and even when they are, they might be medically unsuitable for transplants. These considerations influenced the government in the revision of the Act. Secondly, the findings of the study suggest maintaining the current family-based regulations for living organ donation in Bangladesh. Furthermore, the study highlighted a potential consequence: amending the regulation to permit donations to unrelated recipients could significantly amplify the issue of organ selling and buying. While Islam advises Muslims to be compassionate towards all humankind, it also encourages Muslims to prioritize saving the lives of family members. This religious belief limits Muslims from donating organs to family members. (shrink)

The government of Bangladesh approved the human organ transplantation law in 1999 and updated it in 2018. This legislation approved both living‐related donor and posthumous organ transplantation. The law only allows family members to legally donate organs to their relatives. The main focus of this study was to explore how Bangladeshis make donation decisions on familial organs for transplantation. My ethnographic fieldwork with forty participants (physicians and nurses, a healthcare administrator, organ donors, recipients, and their relatives) disclosed that the organ (...) donation decision was family‐based. An assessment of the relationship between religion, culture, and biomedicine leads to the conclusion that deciding on donating organs to relatives is primarily family‐based and is perceived to be steeped in Islamic ethical principles and religious cultural tradition. The family‐based consent and motivation for donor‐recipient pair organ transplantation strengthen an altruistic environment for the family and act as the moral and legal authority that ensures ethical healthcare outcomes for Bangladeshis.

Social media is a prominent communication platform. Its active usage permeates all generations and it is imperative that the platform be fully optimized for knowledge transfer and innovation diffusion. However, there are several considerations regarding platform usage, including media affordances. Social media affordances enable users to interact with the world around them through features of modality, agency, interactivity, and navigation. Previous studies have indicated that social media affordances significantly influence user behavior and usage. However, research exploring the effect of social (...) media affordances on knowledge acquisition and the reduction of decision-making complexities is limited. Therefore, focusing on 179 paddy farmers in Malaysia, this study examined the effect of social media affordances on information quality, knowledge acquisition, and complexity reduction regarding innovation adoption decisions using a quantitative approach. This study’s findings reveal that social media affordances have a significant effect on perceived information quality, knowledge acquisition, and complexity reduction. (shrink)

Experiences like pains, pleasures, and emotions have affective phenomenal character: they feel pleasant or unpleasant. Imperativism proposes to explain affective phenomenal character by appeal to imperative content, a kind of intentional content that directs rather than describes. We argue that imperativism is on the right track, but has been developed in the wrong way. There are two varieties of imperativism on the market: first-order and higher-order. We show that neither is successful, and offer in their place a new theory: reflexive (...) imperativism. Our proposal is that an experience P feels pleasant in virtue of being constituted by a Command with reflexive imperative content, while an experience U feels unpleasant in virtue of being constituted by a Command with reflexive imperative content : More of P!Less of U! If you need a slogan: experiences have affective phenomenal character in virtue of commanding us Get more of me! Get less of me! (shrink)

a elaboração de uma ontologia fenomenológica era uma possibilidade inscrita no próprio projeto filosófico husserliano. Em que sentido, no entanto, o espírito da máxima da ?volta às coisas mesmas? serviu de inspiração ao retorno à questão do ser?

É na tentativa de responder a essas questões que nos propomos examinar a posição especial de Heidegger (...) face ao problema da articulação da ontologia com a fenomenologia. Nossa preferência é ditada pela própria originalidade do emprego da fenomenologia, no autor de Ser e Tempo.

Social capital and scaling social impact are two of the most important concepts within social entrepreneurship and social enterprise research. However, what role social capital plays in scaling social impact is less understood and academic literatures on the connection of these two crucial concepts are fragmented and scattered. To fill this research gap, we have conducted a bibliometric review to inform academics and researchers the salient agents in the field and categorize the conceptual structure of the knowledge base. Using science (...) mapping techniques, we have analyzed 1549 relevant documents from SCOPUS that are published between 1986 and 2021. The primary objective of this review is to uncover the size, growth trajectory, and geographic distribution of literatures related to social capital's role in scaling social impact. Additionally, we have also analyzed key publishing journals, authors, and documents to map the intellectual structure and research fronts of the domain. The review shows that there is a reasonable accumulation of scientific knowledge concerning social capital's role in scaling social impact in the last three decades. Another key finding is that, some of the keywords identified within the research fronts are closely aligned with a number of UN-SDG goals. This is the first study to systematically map social capital's role in scaling social impact literature with the help of a science mapping tool called bibliometric analysis. This work provides a clear overview of the evolution of the research field and presents potentially important research gaps that require further attention. (shrink)

Based on the Lotka–Volterra system, a pest-natural enemy model with nonlinear feedback control as well as nonlinear action threshold is introduced. The model characterizes the implementation of comprehensive prevention and control measures when the pest density reaches the nonlinear action threshold level depending on the pest density and its change rate. The mortality rate of the pest is a saturation function that strictly depends on their density while the release of natural enemies is also a nonlinear pulse term depending on (...) the density of real-time natural enemies. The exact impulsive and phase sets are given. The definition and properties of the Poincaré map corresponding to the pulse points on the phase set are provided. We investigate the existence and stability of boundary and interior order-1 periodic solution. The theoretical analysis developed in the present paper combined with nonlinear controlling measures as well as nonlinear action threshold methods and techniques laid the foundation for the establishment and analysis of other state-dependent feedback control models.
