Artificial Immune Systems (AIS) are intelligent algorithms derived on the principles inspired by human immune system. In this research work, electroencephalography (EEG) signals for four distinct motor movement of human limbs are detected and classified using Negative Selection Classification Algorithm (NSCA). For this study, a widely studied open source EEG signal database (BCI IV - Graz dataset 2a, comprising 9 subjects) has been used. Mel Frequency Cepstral Coefficients (MFCCs) are extracted as selected feature from recorded EEG signals. Dimensionality reduction of (...) data is carried out by applying two hidden layered stacked auto-encoder. Genetic Algorithm (GA) optimized detectors (Artificial Lymphocytes) are trained using Negative Selection Algorithm (NSA) for detection and classification of four motor movements. The trained detectors consist of four sets of detectors, each set is trained for detection and classification of one of the four movements from the other three movements. The optimized radius of detector is small enough not to mis-detect the sample. Euclidean distance of each detector with every training dataset sample is taken and compared with optimized radius of detector as a non-self detector. Our proposed approach achieved a mean classification accuracy of 86.39% for limb movements over 9 subjects with a maximum individual subject classification accuracy of 97.5 % for subject number eight.

The ability to initiate DNA replication is a critical step in the proliferation of all organisms. In bacteria, this process is mediated by an ATP‐dependent replication initiator protein, DnaA, which recognizes and melts replication origin (oriC) elements. Despite decades of biochemical and structural work, a mechanistic understanding of how DnaA recognizes and unwinds oriC has remained enigmatic. A recent study by Pelliciari et al. provides important new structural insights into how DnaA from Bacillus subtilis recognizes and processes its cognate oriC, (...) showing how DnaA uses sequence features encoded in the origin to engage melted DNA. Comparison of the DnaA‐oriC structure with archaeal/eukaryl replication origin complexes based on Orc‐family proteins reveals a high degree of similarity in origin engagement by initiators from di domains of life, despite fundamental differences in origin melting mechanisms. These findings provide valuable insights into bacterial replication initiation and highlight the intriguing evolutionary history of this fundamental biological process. (shrink)

Information of high evidentiary quality plays a crucial role in forensic investigations. Research shows that information provided by witnesses and victims often provide major leads to an inquiry. As such, statements should be obtained in the shortest possible time following an incident. However, this is not achieved in many incidents due to demands on resources. This intersectional study examined the effectiveness of a chatbot (the AICI), that uses artificial intelligence (AI) and a cognitive interview (CI) to help record statements following (...) an incident. After viewing a sexual harassment video, the present study tested recall accuracy in participants using AICI compared to other tools (i.e., Free Recall, CI Questionnaire, and CI Basic Chatbot). Measuring correct items (including descriptive items) and incorrect items (errors and confabulations), it was found that the AI CI elicited more accurate information than the other tools. The implications on society include AI CI provides an alternative means of effectively and efficiently recording high-quality evidential statements from victims and witnesses. (shrink)

Introduction There is a paramount need for moral development for pharmacists and pharmacy students to practice the patient-centered profession. We aimed to explore the current situational judgment utilizing ethical reasoning among undergraduate pharmacy students. Methods A set of ten ethical dilemmas, representing potential real-life situations that the students come across in the university and may face in the future as a pharmacist were developed by a team of students, academic staff, and stakeholders. These ethical dilemmas were validated, checked for accuracy, (...) and piloted. An online questionnaire was created consisting of these ten scenarios as open-ended questions and administered to fourth year and fifth year PharmD students in a public university located at the city of Mecca, Saudi Arabia, asking them how they would react in that situation. Responses of the participants were analyzed using thematic analysis independently by four researchers and inter-rater agreement were achieved through consensus. Results Out of 205, 186 students completed the questionnaire with a response rate of 90.7%. Analysis and resulted in the generation of 32 codes, which were then categorized into seven overarching themes: student engagement, social and professional responsibility, academic integrity, legal obligation, moral obligation, signposting, and moral engagement and patient safety. Conclusions Undergraduate pharmacy students experience complex state of mind in connection with ethical reasoning. The participants’ situational judgment were driven by cultural norm, authority, and responsibility. Student engagement is also affected by the state of mind and feelings of mutual trust, perceived cultural influence and peer pressure. The students were prone to seek help from university administrators or teachers when faced with situations in which they were helpless. (shrink)

Transcendental Ego is the principle of principles that philosophization of great philosophers such as Husserl has been based upon it. Husserl, too, as a follower of Descartes meditations and philosophy with attemption in intentionality of transcendental ego accepts it as the base of principles of philosophization and declares himself as a New Cartesian. In this study, the author develops an original reading of the Cartesian Meditation. This text, far from giving rise to a “Transcendental solipsism”, leads to a constitution of (...) intersubjectivity on various levels (“primordial”, “Intersubjective” et “Objective”). In its center, a “Phenomenological Construction” operates, i.e. a methodological piece that masters the genetic approach of intersubjectivity. Closely following the “almost mathematical” rigour of this crucial text of Husserl’s phenomenology, in this way equally tackles the issue of the constitution of the experience of the other and the truly intersubjective structure of transcendental subjectivity. This study concludes with the metaphysical results of the analysis of the experience of the other. (shrink)

We survey the meta-ethical tools and institutional processes that traditional Islamic ethicists apply when deliberating on bioethical issues. We present a typology of these methodological elements, giving particular attention to the meta-ethical techniques and devices that traditional Islamic ethicists employ in the absence of decisive or univocal authoritative texts or in the absence of established transmitted cases. In describing how traditional Islamic ethicists work, we demonstrate that these experts possess a variety of discursive tools. We find that the ethical responsa—i.e., (...) the products of the application of the tools that we describe—are generally characterized by internal consistency. We also conclude that Islamic ethical reasoning on bioethical issues, while clearly scripture-based, is also characterized by strong consequentialist elements and possesses clear principles-based characteristics. The paper contributes to the study of bioethics by familiarizing non-specialists in Islamic ethics with the role, scope, and applicability of key Islamic ethical concepts, such as “aims” (maqāṣid), “universals” (kulliyyāt), “interest” (maṣlaḥa), “maxims” (qawā`id), “controls” (ḍawābit), “differentiators” (furūq), “preponderization” (tarjīḥ), and “extension” (tafrī`).

for income tax evasion, but it cannot be defended for pursuing otherwise innocent people. The man responsible for bringing these four cases, Roanoke U.S. Attorney John Brownlee, has defended his actions (Rocktown Weekly, April 27-May 3, 2006, p. 11): “We have to properly track money going overseas so it’s not going to the wrong places.” But, this could be done without this law. Even though 12 agencies investigated these money transfers, led by the FBI, none charged that any went to (...) terrorist groups. “We know you are not the bad guys,” another prosecuting attorney has said. A group of agencies went looking for Middle Eastern Muslim terrorists around here after 9/11. Not finding any, they arrested four anti-Saddam Muslim Kurds, just like autoworkers went after a Chinese-American when they could not find any Japanese to beat up. This is an appalling travesty of justice. These men helped neighbors who needed to send money to families for medical care when there was no other way to do so, there being no banking system in Iraq. These men are all civic-minded, translating for schools, hospitals, and the courts since arriving here. They are being prosecuted for helping their neighbors in times of trouble. In their initial investigations, the FBI inquired whether these men knew Saddam Hussein or Osama bin Laden. This makes as much sense as Abraham Lincoln ordering Union troops to investigate runaway slaves in the North to find out their knowledge of Jefferson Davis or John Singleton Mosby and then prosecuting them for sending money to their families in the South via an illegal method. Citizens of Harrisonburg should express their support for these four men and demand that these charges be dropped. The FBI and the U.S. Attorney’s office in Roanoke should get back to what they are supposed to be doing and stop degrading our American system with such outrageous prosecutions. (shrink)

In response to nutrient limitation, many animals, including Caenorhabditis elegans, slow or arrest their development. This process requires mechanisms that sense essential nutrients and induce appropriate responses. When faced with nutrient limitation, C. elegans can induce both short and long‐term survival strategies, including larval arrest, decreased developmental rate, and dauer formation. To select the most advantageous strategy, information from many different sensors must be integrated into signaling pathways, including target of rapamycin (TOR) and insulin, that regulate developmental progression. Here, how (...) nutrient information is sensed and integrated into developmental decisions that determine developmental rate and progression in C. elegans is reviewed. (shrink)

This paper interprets John von Neumann's views on the proper role of mathematics in science, with attention to its implications for economics. The evolution of von Neumann's thought over his lifespan, an examination of which is greatly aided by some self-conscious appraisals of von Neumann himself, suggests that von Neumann ended by taking a very pragmatic approach to the use of mathematics. One can almost characterize it as an engineering approach to the philosophy of mathematics since von Neumann takes mathematics (...) to be justified by its applications. This approach, which is surprisingly non-technical and hence accessible to general readers, is then placed in the context of his wider world-view. (shrink)

Research in science, technology, engineering, and mathematics fields has become much more complex in the twenty-first century. As a result, the students of our Graduate School, who are all Ph.D. candidates, need to be trained in essential skills and processes that are crucial for success in academia and beyond. Some research problems are inherently complex in that they raise deep moral dilemmas, such as antimicrobial resistance, sustainability, dual-use research of concern, and human cloning. Dealing with moral dilemmas is one of (...) several core competencies that twenty-first-century Ph.D. students must acquire. However, this might prove difficult for STEM Ph.D. students who have had limited exposure to moral philosophy. Since the task of dealing with moral dilemmas in STEM research requires input from both scientific and philosophical disciplines, it is argued with the help of the 4 examples above that this task be explicitly modelled as an interdisciplinary process. Furthermore, it is argued that a particular model from the interdisciplinary education literature could serve as a learning tool to support ethical decision-making in research ethics and integrity courses for doctoral students.

This paper unravels an unprecedented interplay between board gender diversity (BGD) and corporate environmental, social, and governance (ESG) disputes among Chinese A-share-listed nonfinancial companies from 2017 to 2021. Framed within a knowledge-based and sensemaking perspective of institutional frameworks, the research not only illuminates the profound impact of internal (corporate governance ratings) and external (regional institutional development) institutional factors on this intricate relationship but also brings to light a paradigm-shifting revelation. The study employed a diverse set of empirical tests, ranging from (...) ordinary least squares regression to advanced methods such as the generalized method of moments, two-stage least squares, and propensity score matching, providing a nuanced and comprehensive analysis. The findings highlight the pivotal role of female directors in significantly mitigating ESG disputes. A mechanism analysis further uncovers that internal and external institutional quality are potent positive moderators in shaping the BGD–ESG dispute dynamic. This research has profound implications, providing valuable insights for stakeholders, policymakers, and scholars, offering a comprehensive understanding of how gender diversity fosters sustainability while unravelling the intricate tapestry of internal and external institutional dynamics that shape ESG outcomes.

A system of system’s ability to function is derived from the integration of systems from different sources. An SOS’s systems serve two purposes: first, to accomplish their own specific aims, and second, to provide resources to the SOS as a whole. In the last few decades, machine learning and data analytics have been widely used in system design and acquisitions. Every organisation that acquires a sophisticated system employs some type of data analytics to evaluate the system’s independent objectives, which is (...) universally accepted. Data analytics and decision-making regarding the independent system is rarely shared across SOS stakeholders, even though the systems contribute to and benefit from the larger SOS. The goal of this research is to determine how the exchange of data sets and the corresponding analytics by SOS stakeholders can improve SOS capacity. Predicting SOS capabilities by exchanging relevant data sets and prescribing information connections between systems, we propose to use machine learning techniques. This article serves as an intermediate analysis of the above research work and aims to estimate the benefit of information sharing among the SOS stakeholders. In this research, we have applied different machine learning models to the IBM HR analytics data set to determine the corresponding analytics by SOS stakeholders that can improve SOS capacity. We propose using machine learning techniques to forecast SOS capabilities through the sharing of relevant data sets, and we prescribe the information linkages across systems to make this possible. This paper provides an update on the progress being made toward the aforementioned research project, and its primary focus is on developing a method to put a dollar amount on the benefits of information sharing among the many parties involved in the SOS.

This study examines the influence of board independence on firm agency cost among listed firms in Bangladesh, which feature concentrated ownership and high insider representation on corporate boards. This study uses three measures of agency cost: the ‘expense ratio’, the ‘Q-free cash flow interaction’ and the ‘asset utilization ratio’. The finding of the study is that board independence can reduce the firm agency cost only under ‘asset utilization ratio’ measure of agency cost. These findings are robust to several robustness tests. (...) Furthermore, the non-linearity tests suggest that the benefit of outside independent directors is generally plausible as a factor controlling agency costs in the case of a medium level of board independence. Overall, these findings do not reject the validity of agency theory, supporting the Anglo-American orthodoxy promoting outside independent directors as good monitors. (shrink)

The authors then postulate four hypotheses regarding various aspects of whistleblowing. These Hypotheses were than tested using a survey administered to a sample of U.S.A. and Croatian managers. Finally, the paper discusses the findings and practical implications for contemporary managers in the international arena. (shrink)

Applying the resolution–scale relativity principle to develop a mechanics of non-differentiable dynamical paths, we find that, in one dimension, stationary motion corresponds to an Itô process driven by the solutions of a Riccati equation. We verify that the corresponding Fokker–Planck equation is solved for a probability density corresponding to the squared modulus of the solution of the Schrödinger equation for the same problem. Inspired by the treatment of the one-dimensional case, we identify a generalization to time dependent problems in any (...) number of dimensions. The Itô process is then driven by a function which is identified as establishing the link between non-differentiable dynamics and standard quantum mechanics. This is the basis for the scale relativistic interpretation of standard quantum mechanics and, in the case of applications to chaotic systems, it leads us to identify quantum-like states as characterizing the entire system rather than the motion of its individual constituents.

Building on the notion that organizations are congruence seeking systems, this study investigates the impact of green investing on corporate environmental violations (CEVs). The research sample consists of China's A-share-listed companies for the period 2009–2020. The study employs a robust analytical framework that integrates least squares dummy variable approach, different proxies for regressors and moderators, and instrumental variable technique. Based on the rigorous methods, empirical analysis reveals that green investing helps mitigate CEVs, aligning with the theoretical premise of environmental strategic (...) congruence. The moderating results indicate that elevated CEO ability and a higher proportion of female directors on boards enhances strategic congruence and amplifies the alleviating effects of green investing on CEVs. Furthermore, cross-sectional analysis suggests that the mitigating effect of green investing on CEVs is more pronounced for firms in sensitive sectors, state-owned, and lacking internal controls for environmental, health, and safety. This research contributes nuanced insights on the role of strategic congruence in sustainable finance and governance and presents practical implications for policymakers, managers, and corporate leaders navigating the intricate landscape of environmental responsibility within an emerging market.

Sustainability is concerned with the impact of present actions on the ecosystems, societies, and environments of the future. Such concerns should be reflected in the strategic planning of sustainable corporations. Strategic intentions of this nature are operationalized through the adoption of a long-term focus and a more inclusive set of responsibilities focusing on ethical practices, employees, environment, and customers. A central hypothesis, that we test in this paper is that companies which attend to this set of responsibilities under the term (...) superior sustainable practices, have higher financial performance compared to those that do not engage in such practices. The target population of this study consists of the top 100 sustainable global companies in 2008 which have been selected from a universe of 3,000 firms from the developed countries and emerging markets. We find significant higher mean sales growth, return on assets, profit before taxation, and cash flows from operations in some activity sectors of the sample companies compared to the control companies over the period of 2006–2010. Furthermore, our findings show that the higher financial performance of sustainable companies has increased and been sustained over the sample. Notwithstanding sample limitation, causal evidence reported in this paper suggests that, there is bi-directional relationship between corporate social responsibilities practices and corporate financial performance.

Most of the hypothesis supported and demonstrate the positive response from the Pakistani consumers having experience in shopping through social commerce platforms. The findings of this study will help scholars and managers to understand the attitude of Pakistani consumers. (shrink)

This paper investigates the relationship between director independence and firm performance, as well as ownership of firms and firm performance in Malaysia. We find that independent outside directors and foreign directors have a significant positive effect on firm performance after controlling for the influence of other corporate governance variables such as firm ownership and board sizes. The study demonstrates that when a critical mass of outside directors' independence is achieved, this has a significant economic impact on the firm performance. The (...) results have implications for rethinking board composition requirements in the emerging markets. [PUBLICATION ABSTRACT]. (shrink)

The article is an introduction to the use of the principle of falsification in economic science.

The purpose of this paper is to make sense of Marx's own view about justice in the light of the controversy between classical Marxism and normative Marxism. Normative Marxism claims that Marx's condemnation of capitalist exploitation and his conception of communism entertain a principle of justice, while classical Marxism does not allow any such principle in Marx's thought. However, I argue that although Marx uses normative terms, he does not provide any specific theory of justice. Marx's condemnation of capitalism is (...) based on the real interests of the workers, not on their moral norms, and his communist principle is a principle of distribution (as a principle of equality), not a principle of justice.

This study examines the influence of managerial ownership on firm agency costs among listed firms in Bangladesh. This is an institutional setting that features a mixture of agency costs. This institutional setting has a concentration of ownership by managers, but the firms are not solely owned by managers. The extant literature suggests that the sacrifice of wealth by the principal and potential costs associated with monitoring the agents is known as the agency cost. This study uses three measures of agency (...) cost: the ‘expense ratio’, the ‘Q-free cash flow interaction’, and the ‘asset utilisation ratio’. The finding of the study is that managerial ownership reduces the firm agency cost only under the ‘asset utilisation ratio’ measure of agency cost; this is robust with regard to a number of robustness tests. Furthermore, the non-linearity tests suggest that the convergence of interest is evident with very high and low levels of managerial ownership. The entrenchment effect by the owners is evident at moderate levels of managerial ownership. Although there has been great scepticism among management researchers on the validity of agency theory, overall, the findings of this study do not reject the validity of agency theory. Given that the entrenchment by managers is evident at certain levels of ownership and that the agency problem may still exist between insiders and outsiders, legislative guidelines for controlling share ownership may be required.

During the initial phases of the COVID-19 pandemic, stress and anxiety were pervasive among the masses due to high morbidity and mortality. Besides the fear of coronavirus was also particularly driven by social media. Many people started to look for faith and spiritual connections to gain comfort. The role of spiritual ties and religious beliefs in relation to coping with pandemic stress gained the attention of researchers in some parts of the world. This cross-sectional survey aimed at assessing the intensity (...) of stress and anxiety symptoms experienced by people and how much they were alleviated by employing spiritual connections. The study sample comprises 795 respondents with 52% males and 48% females living in Saudi Arabia. The brief online study questionnaire collected data about background variables, anxiety and stress scale from DASS-21, and items from the WHOQOL instrument assessed the use of spiritual beliefs to cope. Multiple regression models were tested to determine the role of spiritual connections after adjusting demographic variables. Results illustrated that after adjusting for gender and age, participants' anxiety symptoms decreased by units with each unit increase in the use of spiritual connections, and participants’ stress symptoms reduce by units with each unit increase in coping with spirituality. Additionally, females’ risk to experience anxiety and stress symptoms was more than males and, respectively. An increase in age decreases the likelihood of experiencing anxiety symptoms and stress symptoms by and units respectively. Findings support the protective role of spiritual connections despite small beta coefficients. The social and cultural context in Saudi Arabia favors deep-rooted connections with spirituality and faith. Our findings support that the reliance on spiritual connections helped older people to deal with exaggerated fear during the initial phase of the COVID-19 pandemic and reduces the risk of experiencing anxiety and stress symptoms. Females and younger participants were relatively vulnerable to developing these symptoms. We discussed these findings considering some recent studies that reported similar relationships and made recommendations for future research. (shrink)

In this article, we investigated a deterministic model of pneumonia-meningitis coinfection. Employing the Atangana–Baleanu fractional derivative operator in the Caputo framework, we analyze a seven-component approach based on ordinary differential equations. Furthermore, the invariant domain, disease-free as well as endemic equilibria, and the validity of the model’s potential results are all investigated. According to controller design evaluation and modelling, the modulation technique devised is effective in diminishing the proportion of incidences in various compartments. A fundamental reproducing value is generated by (...) exploiting the next generation matrix to assess the properties of the equilibrium. The system’s reliability is further evaluated. Sensitivity analysis is used to classify the impact of each component on the spread or prevention of illness. Using simulation studies, the impacts of providing therapy have been determined. Additionally, modelling the appropriate configuration demonstrated that lowering the fractional order from 1 necessitates a rapid initiation of the specified control technique at the largest intensity achievable and retaining it for the bulk of the pandemic’s duration.
