In this paper, we draw on insights from theories in the management and corporate governance literature to develop a theoretical model that makes explicit the links between a firm’s corporate social responsibility related board attributes, its board CSR strategy, and its environmental and social performance. We then test the model using structural equation modeling approach. We find that the greater the CSR orientation of the board, the more proactive and comprehensive the firm’s CSR strategy, and the higher its environmental and (...) social performance. Moreover, we find this link to be endogenous and self-reinforcing, with superior CSR performers tending to further strengthen their board CSR orientation. This result while positive is also suggestive of the widening of the gap between the leads and laggards in CSR. Therefore, the question arises as to how ‘leaders’ are using their superior CSR competencies seen by many scholars as a source of corporate competitive advantage. Stakeholders of corporations therefore need to be cognizant of this aspect of CSR when evaluating a firm’s CSR activities. Policy makers also need to be cognizant of these concerns when designing regulation in this field. (shrink)

We examine the link between a firm’s environmental and social disclosures and measures of its risk including total, systematic, and idiosyncratic risk. While we do not find any link between a firm’s E and S disclosures and its systematic risk, we find a negative and significant association between these disclosures and a firm’s total and idiosyncratic risk. These are novel findings and are consistent with the predictions of the stakeholder theory and the resource-based view of the firm suggesting that firms (...) which make extensive and objective E and S disclosures promote corporate transparency that can help them build a positive reputation and trust with their stakeholders. This in turn can help mitigate the firms' idiosyncratic/operational risk. These findings are important for all corporate stakeholders including managers, employees, and suppliers who have a significant economic interest in the survival and success of the firm. (shrink)

This study is based on the natural resource based view, which examines the impact of holistic marketing orientation on business performance by defining the role of enablers and mediators. The drivers, including corporate social responsibility and environmental culture influence, are tested by analyzing the role of sustainable competitive advantage as a mediator. The analysis is based on 298 samples collected from top and middle-level managers working in the pharmaceutical industry. Structural equation modeling was undertaken using Smart PLS 3.2.8. The research (...) outcomes reveal that corporate social responsibility and environmental culture have a substantial impact on green marketing orientation. The results show that GMO has a significant direct and indirect impact on business performance while a full mediation of sustainable competitive advantage exists between the green marketing orientation and business performance. The outcomes will facilitate managers in green marketing strategy and decision making in the long-term, with 3-fold benefits in addition to strengthening their competitiveness. (shrink)

The aim of the study is to reveal the underlying structure of issues of university students taking online classes during the COVID-19 pandemic period. The overall design of the study includes a review of contemporary literature and field survey for data collection and analysis. Discourse of literature coupled with expert opinion has been employed for identification of issues. Interpretive Structural Modeling is used for the determination of intra-issue relationships and analyzing the underlying structure. Cross impact matrix multiplication applied to classification (...) is used as a technique for classifying issues on the basis of driving–dependence power. Results of the literature show that there are 21 major issues faced by the students taking online classes. ISM shows that lack of institutional guidelines, lack of regulators’ guidelines, stress of pandemic situation, and abrupt start of online classes are the most critical issues. MICMAC analysis reveals that there is no autonomous issue, 4 are independent, 6 other issues are dependent, and the remaining 11 are linking. This is a valuable study having practical implications for regulators, students, parents, and society to understand the current problem. It is an original attempt that contributes toward literature in the form of a structural model and a diagram of classification of issues. (shrink)

Monitoring and assistive technologies (MATs) are being used more frequently in healthcare. A central ethical concern is the compatibility of these systems with the moral preferences of their users—an issue especially relevant to participatory approaches within the ethics-by-design debate. However, users’ incapacity to communicate preferences or to participate in design processes, e.g., due to dementia, presents a hurdle for participatory ethics-by-design approaches. In this paper, we explore the question of how the value preferences of users in the field of dementia (...) care can be integrated into AI-based MATs. First, we briefly introduce different ethics-by-design approaches and explain the challenges they face in dementia care. Next, we introduce a novel approach for addressing these challenges. Through a qualitative content analysis of interviews with persons with dementia and their family caregivers (n = 27), we identified multiple ideal–typical value preference profiles. We then applied these profiles in a computer simulation, by which we also introduce the concept of ethical compliance quantification to scale the moral preferences of the interviewees for the simulation. Finally, we discuss study results, the advantages of using computer simulations, and general study limitations before drawing conclusions for further research. The study contributes to the ongoing debate on participatory ethics-by-design by defining on the basis of empirical data ideal–typical value preference frameworks that can be used to guide MAT actions and their outcomes. Going forward, MAT end-users with dementia and other communication-impaired persons could be enabled to choose a value profile that best fits their moral preferences. (shrink)

Keyword extraction refers to the process of selecting most significant, relevant, and descriptive terms as keywords, which are present inside a single document. Keyword extraction has major applications in the information retrieval domain, such as analysis, summarization, indexing, and search, of documents. In this paper, we present a novel supervised technique for extraction of keywords from medium-sized documents, namely Corpus-based Contextual Semantic Smoothing. CCSS extends the concept of Contextual Semantic Smoothing, which considers term usage patterns in similar texts to improve (...) term relevance information. We introduce four more features beyond CSS as our novel contributions in this work. We systematically compare the performance of CCSS with other techniques, when implemented over INSPEC dataset, where CCSS outperforms all state-of-the-art keyphrase extraction techniques presented in the literature.

Megastable chaotic systems are somehow the newest in the family of special chaotic systems. In this paper, a new megastable two-dimensional system is proposed. In this system, coexisting attractors are in some islands, interestingly covered by megalimit cycles. The introduced two-dimensional system has no defined equilibrium point. However, it seems that the origin plays the role of an unstable equilibrium point. Therefore, the attractors are determined as hidden attractors. Adding a forcing term to the system, we can obtain chaotic solutions (...) and coexisting strange attractors. Moreover, the effect of three different values of the forcing term’s amplitude is studied. The dynamical properties of the designed system are investigated using attractor plots, bifurcation diagrams, and Lyapunov Exponents diagram. Phase portraits of the novel megastable oscillator are presented by FPGA design. Xilinx system generator block diagrams of the proposed system and trigonometric functions are also presented.

A multifaceted, holistic approach to identifying potential predictors is needed to eradicate workplace bullying. The current study investigated the impact of an unfavourable organisational climate that plays a role in breeding workplace bullying. The present study also postulated that individual personality differences mediate between a caring climate and workplace bullying. Similarly, the interaction between workplace bullying and personality impacts PTSD. We also checked the role of workplace bullying as a mediator between a caring climate and PTSD. This research tested all (...) the proposed hypotheses, and the study was conducted in Pakistan. The data is analysed using the two-step partial least square structural equation modelling procedure. The first part assesses the measurement model, while in the second step, the structural model is evaluated. The results supported all the proposed hypotheses of this study. Type A behaviour moderated the caring climate—person-related bullying relationship, whereas it did not moderate the caring climate—work-related bullying in the suggested direction. Type A behaviour is moderated for both types of bullying and PTSD. Results also show significant indirect effects of a caring climate on PTSD through workplace bullying. This study will contribute theoretically to filling the literature gap on studies of climate-bullying and bullying-stress using contingency factors. (shrink)

With the increasing volume of data transmission through insecure communication channels, big data security has become one of the important concerns in the cybersecurity domain. To address these concerns and keep data safe, a robust privacy-preserving cryptosystem is necessary. Such a solution relies on chaos encryption algorithms over standard cryptographic methods that possess multistage encryption levels, including high speed, high security, low compute overheads, and procedural power, among other characteristics. In this work, a secure image encryption scheme is proposed using (...) linear feedback shift register and chaos-based quantum chaotic map. The focus of the scheme is mainly dependent on the secret keys from the input of the algorithm. The threat landscape, the statistical test analysis, along critical comparisons with other schemes indicate that the presented algorithm is significantly secure and is resistant to a wide range of different attacks such as differential and statistical attacks. The proposed method has sufficiently higher sensitivity and security when compared to existing encryption algorithms. Several security parameters validated the security of proposed work such as correlation coefficient analyses among the neighboring pixels, entropy, the number of pixels change rate, unified average change intensity, mean square error, brute force, key sensitivity, and peak signal to noise ratio analyses. The randomness of the ciphers produced by the proposed technique is also passed through NIST-800-22. The results of NIST indicate that the ciphers are highly random and do not produce any type of periodicity or pattern. (shrink)

Online forums have become the main source of knowledge over the Internet as data are constantly flooded into them. In most cases, a question in a web forum receives several responses, making it impossible for the question poster to obtain the most suitable answer. Thus, an important problem is how to automatically extract the most appropriate and high-quality answers in a thread. Prior studies have used different combinations of both lexical and nonlexical features to retrieve the most relevant answers from (...) discussion forums, and hence, there is no standard/general set of features that could be effectively used for relevant answer/reply post classification. However, this study proposed an answer detection model that is exclusively relying on lexical features and employs a random forest classifier for classification of answers in discussion boards. Experimental results showed that the proposed answer detection model outperformed the baseline technique and other state-of-the-art machine learning algorithms in terms of classification accuracy on benchmark forum datasets.

In lieu of an abstract, here is a brief excerpt of the content:Cocceius and the Jewish CommentatorsAdina M. YoffieThe case of Johannes Cocceius defies the commonplace that Leiden University (and perhaps post-Reformation, confessionalized Europe in general) turned away from humanist scholarship in the first quarter of the seventeenth century. In 1650 Cocceius (1603-69), a Bremen-born Oriental philology professor at Franeker, joined the Leiden theological faculty and wrote a treatise, Protheoria de ratione interpretandi sive introductio in philologiam sacram (De ratione). He (...) praised such rabbinic exegetes as Rashi (1040-1105) and David Kimchi (ca. 1160-ca. 1235) in humanist terms for their erudition. At the same time the "new" Cartesian philosophy was taking hold in the arts faculty, and mathematics instruction was encroaching on scholastic formal logic.1 Leiden would become famous for Cartesianism, mathematics, and "Calvinist Copernicanism" in the second half of the seventeenth century, but Cocceius still worked in the tradition of advanced humanist scholarship that had made the institution famous in the sixteenth century.2Leiden's earlier reputation was due in large part to the biblical humanist work of such Renaissance polymaths as Joseph Justus Scaliger (1540-1609) and Hugo Grotius (1583-1645), but by Cocceius's time Leiden theologians were subject to greater Church and State control. As Jonathan Israel and Edwin Rabbie have shown, in response to the controversy that surrounded Jacobus Arminius and his stand on predestination, the Synod of Dordrecht (Dort) drafted an anti-Arminian statement in 1619; any professor who did not sign was subject [End Page 383] to exile from the republic in addition to dismissal from his post.3 Innovative theology, exegesis, and philology suffered as professors, fearing State and Church reprisals, turned to "dogmatic humanism." As Henk Jan de Jonge has explained, this meant that "almost all the theologians of seventeenth-century Leiden who concerned themselves with the explanation of the New Testament placed exegesis at the service of dogmatic objectives."4 Unlike his fellow Leiden theologians, Cocceius pursued biblical humanism and Christian Hebraism through the study of Hebrew, Greek, and Aramaic-and he did so in a unique way. He was not the first to use Jewish commentaries and even Jewish post-biblical literature for the purpose of reconstructing the original Hebrew Bible, but he was innovative in praising rabbinic scholars as fellow humanists and in incorporating their scholarship into his Christological exegesis and philosophy. He did so, furthermore, not as an independent scholar or pastor or even as a professor of Hebrew; but as the holder of a university chair in theology at a confessionalized university in a century hostile to his brand of late humanism.Although he came to Leiden as a theologian, Cocceius had impressive training as an Orientalist. He had studied with the famous scholar Sixtinus Amama (1593-1629) and polished his Hebrew and Aramaic by working with a Jewish tutor from Hamburg.5 While still a student at Franeker, Cocceius wrote a translation and commentary of the Talmudic tractate Sanhedrin. A few years later he began composing commentaries on the Pentateuch, and, by the time he arrived at Leiden, he had completed one lecture, series of lectures, or piece of writing on every book of the Old Testament. These commentaries were based not only on Cocceius's extensive knowledge of Oriental languages but also on his readings of medieval Jewish commentators. These were the same commentators that Cocceius would later praise in chapter eight of the De ratione.These humanist achievements were much at variance with Cocceius's public persona as perhaps the most prominent Dutch Calvinist theologian of the seventeenth century. For approximately 100 years after his death in 1669 a faction of Leiden theologians calling themselves "Cocceians" battled the "Voetians," followers of Gisbertus Voetius, for the soul of the Dutch Church.6 At Leiden he lectured on the Pauline Epistles, a typical subject for a seventeenth-century Calvinist theologian, and he worked on his famous theological tract, the salvation-historical Summa doctrinae de foedere et testamento Dei (1648). Neither the De ratione nor his voluminous biblical commentary (except [End Page 384] for a short treatise on the last six chapters of Deuteronomy) was published in Cocceius's lifetime. His son Johann Heinrich released these and his father's... (shrink)
