Drawing on insights from social learning and social cognitive perspectives and research on the multilevel reality of leadership influences, we developed and tested a multilevel model that examines mechanisms and conditions through which ethical leadership deters work unit- and individual-level ostracism. Based on two field studies using multiple measurement points, we found that at the work unit level of analysis, relational climate partially mediates the negative relationship between ethical leadership and work unit-level ostracism whereas state mindfulness partially mediates the cross-level (...) influence of ethical leadership on individual-level ostracism. Contrary to our hypothesis, we found that the relationship between ethical leadership and relational climate was stronger when work units had a more mechanistic structure, and not when it had an organic work unit structure. Finally, we found that relational climate not only moderates the relationship between state mindfulness and individual-level ostracism, but also moderates the indirect influence of ethical leadership on individual-level ostracism through state mindfulness such that the indirect effect is stronger when relational climate is high as opposed to low. These findings highlight the individual- and work unit-level conditions and mechanisms through which ethical leadership relates to decreased ostracism at work, and thus extends theory and research on ethical leadership and ostracism.

This paper presents and discusses several methods for reasoning from inconsistent knowledge bases. A so-called argued consequence relation, taking into account the existence of consistent arguments in favour of a conclusion and the absence of consistent arguments in favour of its contrary, is particularly investigated. Flat knowledge bases, i.e., without any priority between their elements, are studied under different inconsistency-tolerant consequence relations, namely the so-called argumentative, free, universal, existential, cardinality-based, and paraconsistent consequence relations. The syntax-sensitivity of these consequence relations is (...) studied. A companion paper is devoted to the case where priorities exist between the pieces of information in the knowledge base.

This paper first provides a brief survey of a possibilistic handling of default rules. A set of default rules of the form, "generally, from α deduce β", is viewed as the family of possibility distributions satisfying constraints expressing that the situation where α and β is true has a greater plausibility than the one where α and ⇁β is true. When considering only the subset of linear possibility distributions, the well-known System P of postulates proposed by Kraus, Lehmann and Magidor, (...) has been obtained. We also present two rational extensions: one based on the minimum specificity principle and the other is based on the lexicographic ordering. The second part of the paper presents an empirical study of three desirable properties for a consequence relation that capture default reasoning: Rationality, Property Inheritance and Ambiguity Preservation. An experiment is conducted to investigate 13 patterns of inference for the test of these properties. Our experimental apparatus confirms previous results on the relevance of System P, and enforces the psychological relevance of the studied properties. (shrink)

This paper investigates simple syntactic methods for revising prioritized belief bases, that are semantically meaningful in the frameworks of possibility theory and of Spohn''s ordinal conditional functions. Here, revising prioritized belief bases amounts to conditioning a distribution function on interpretations. The input information leading to the revision of a knowledge base can be sure or uncertain. Different types of scales for priorities are allowed: finite vs. infinite, numerical vs. ordinal. Syntactic revision is envisaged here as a process which transforms a (...) prioritized belief bases into a new prioritized belief base, and thus allows a subsequent iteration. (shrink)

Recent studies from Western countries indicate significant levels of questionable research practices, but similar data from low and middle-income countries are limited. Our aims were to assess the prevalence of and attitudes regarding research misconduct among researchers in several universities in the Middle East and to identify factors that might account for our findings. We distributed an anonymous questionnaire to a convenience sample of investigators at several universities in Egypt, Lebanon, and Bahrain. Participants were asked to a) self-report their extent (...) of research misconducts, as well as their knowledge of colleagues engaging in similar research misconducts and b) provide their extent of agreement with certain attitudes about research misconduct. We used descriptive, bivariate, and multivariate logistic regression statistics to analyze the data. Data from 278 participants showed a high prevalence of misconduct, as 59.4% of our respondents self-reported to committing at least one misbehaviors and 74.5% reported having knowledge of any misbehaviors among any of their colleagues. The most common type of self-report misconduct was “circumventing research ethics regulations” followed by “fabrication and falsification”. A significant predictor of misconduct included a lack of “prior ethics training”. Scientific misconduct represents a significant issue in several universities in the Middle East. The demonstration that a lack of “prior ethics training” was a significant predictor of misconduct should lead to educational initiatives in research integrity. Further studies are needed to confirm whether our results can be generalized to other universities in the Middle East. (shrink)

Assisted suicide, many argue, honors self‐determination in returning control of their dying to patients themselves. But physician assistance and measures proposed to safeguard patients from coercion in fact return ultimate authority over this “private and deeply personal” decision to medicine and society.

In a digital communication environment, information security is mandatory. Three essential parameters used in the design process of a steganography algorithm are Payload, security, and fidelity. However, several methods are implemented in information hiding, such as Least Significant Bit (LBS), Discrete Wavelet Transform, Masking, and Discrete Cosine Transform. The paper aims to investigate novel steganography techniques based on agent technology. It proposes a Framework of Steganography based on agent for secret communication using LSB. The most common image steganography databases are (...) explored for training and testing. The methodology in this work is based on the statistical properties of the developed agent software using Matlab. The experiment design is based on six statistical feature measures, including Histogram, Mean, Standard deviation, Entropy, Variance and Energy. For steganography, an Ensemble classifier is used to test two scenarios: embedding a single language message and inserting bilingual messages. ROC Curve represents the evaluation metrics. The result shows that the designed agent-based system with 50% training/testing sample set and 0.2 Payload can pick out the best cover image for the provided hidden message size to avoid visual artifact.

‘Intersectionality’ has now become a major feature of feminist scholarly work, despite continued debates surrounding its precise definition. Since the term was coined and the field established in the late 1980s, countless articles, volumes and conferences have grown out of it, heralding a new phase in feminist and gender studies. Over the past few years, however, the growing number of critiques leveled against intersectionality warrants us as feminists to pause and reflect on the trajectory the concept has taken and on (...) the ways in which it has traveled through time and space. Conceptualizing intersectionality as a traveling theory allows for these multiple critiques to be contextualized and addressed. It is argued that the context of the neoliberal academy plays a major role in the ways in which intersectionality has lost much of its critical potential in some of its usages today. It is further suggested that Marxist feminism offers an important means of grounding intersectionality critically and expanding intersectionality’s ability to engage with feminism transnationally.

In the past decade, the use of the Chapter XI has soared to the detriment of many creditors, workers, and consumers. A good number of cases were not based on imminent insolvency, but on firms attempts to avoid litigation claims against them, to terminate labor or other contractual obligations, or to gain new financing.These filings for Chapter XI highlight the use of bank-ruptcy as a strategic option used by management in running a viable organization. This usage is even advised by (...) some academics and management consultants. (shrink)

This study examined the relationship between urban culture and street vending. Prior research on this topic is limited and inconclusive. Therefore, we have proposed an integrated model to test the positive effect of urban culture on street vending using multiple mediations of consumption patterns, resistance, and microfinance. We tested a sample of 425 responses that reflect the public opinion in Baghdad, Iraq. These responses were collected between September and November 2018. A partial least squares–based structural equation modeling is employed to (...) test the validity of measurement models and the significance of the entire structural model, predictive power, and mediation analysis. We found that resistance mediates the effect of urban culture on street vending; low-income consumption and resistance sequentially mediate the effect of urban culture on street vending, while resistance mediates the effect of a lack of microfinance on street vending. The direct impact of culture on street vending is not significant, and a lack of microfinance positively influences the pervasiveness of trading on streets. This study contributes to the extant literature as it proposed and tested a novel and comprehensive model to analyze the relationship between urban culture and street vending, simultaneously examining the effects of culture, consumption, resistance, and microfinance on street vending.

One of the major problems of intrusion detection concerns the large amount of alerts that intrusion detection systems (IDS) produce. Security operator who analyzes alerts and takes decisions, is often submerged by the high number of alerts to analyze. In this paper, we present a new alert correlation approach based on knowledge and preferences of security operators. This approach, which is complementary to existing ones, allows to rank-order produced alerts on the basis of a security operator knowledge about the system, (...) used IDS and his preferences about alerts that he wants to analyze or to ignore. Our approach is based on the development of a new non-classical logic for representing preferences, called FO-MQCL (First Order - Minimal Qualitative Choice Logic). Our logic extends a fragment of the first order logic by adding a new logical connective. The general idea is to present only alerts that fully fit security operator's preferences and knowledge. And if needed, less preferred alerts can also be presented. (shrink)

The problem of merging multiple sources information is central in many information processing areas such as databases integrating problems, multiple criteria decision making, expert opinion pooling, etc. Recently, several approaches have been proposed to merge classical propositional bases, or sets of (non-prioritized) goals. These approaches are in general semantically defined. Like in belief revision, they use priorities, generally based on Dalal's distance, for merging the classical bases and return a new classical base as a result. An immediate consequence of the (...) generation of a classical base is the impossibility of iterating the fusion process in a coherent way w.r.t. priorities since the underlying ordering is lost. This paper presents a general approach for fusing prioritized bases, both semantically and syntactically, when priorities are represented in the possibilistic logic framework. Different classes of merging operators are considered including conjunctive, disjunctive, reinforcement and adaptive operators. We show that the approaches which have been recently proposed for merging classical propositional bases can be embedded in this setting. The result is then a prioritized base, and hence the process can be coherently iterated. Moreover, we also provide a syntactic counterpart for the fusion of classical bases. (shrink)

This paper investigates the idea of reasoning, in a local (or contextual) way, under prioritized and possibly inconsistent knowledge bases. Priorities are not supposed to be given globally between all the beliefs in the knowledge base, but locally inside sets of pieces of information responsible for inconsistencies. This local stratification offers more flexibility for representing priorities between beliefs. Given this local ordering, we discuss five basic definitions of influence relations between conflicts. These elementary notions of influence between two conflicts A (...) and B exhaustively explore the situations where solving A leads to solve B. Then we propose natural approaches to restore the coherence of a knowledge base on the basis of influence relations between locally-stratified conflicts. (shrink)

A new lifetime distribution, called exponential doubly Poisson distribution, is proposed with decreasing, increasing, and upside-down bathtub-shaped hazard rates. One of the reasons for introducing the new distribution is that it can describe the failure time of a system connected in the form of a parallel-series structure. Some properties of the proposed distribution are addressed. Four methods of estimation for the involved parameters are considered based on progressively type II censored data. These methods are maximum likelihood, moments, least squares, and (...) weighted least squares estimations. Through an extensive numerical simulation, the performance of the estimation methods is compared based on the average of mean squared errors and the average of absolute relative biases of the estimates. Two real datasets are used to compare the proposed distribution with some other well-known distributions. The comparison indicates that the proposed distribution is better than the other distributions to match the data provided. (shrink)

Although Heidegger's philosophical complicity with National Socialism has been the focus of virtually all discussions of his politics, little to no attention has been placed on how the conception of human existence developed in Being and Time might shed light on debates about the self between contemporary liberals and communitarians. By situating Heidegger's early work within these ongoing debates, the author will show how his descriptions of Dasein—especially the descriptions of the relationship between Dasein and its community—are actually more consistent (...) with liberal views of the self than with communitarian interpretations. Heidegger helps to clarify how a thickly constituted, social self may nevertheless stand back from its community in ways that communitarians are hard pressed to explain. In the final section, the author will comment on the compatibility of Heidegger's conception of Dasein with liberalism as a political philosophy, focusing in particular on Heidegger's conception of Mitsein or being-with.

We show in this paper how three continental philosophers (Husserl, Heidegger, and Derrida respectively) respond negatively to the analytic correspondence theory of truth using different notions developed by them (i.e. the notion of Intentionality by Husserl, the notion of Dasein by Heidegger, and the notion of Trace by Derrida). We show that despite the fact that the three philosophers are united against the analytic correspondence theory of truth, there are still deep differences between them which stem from the different tools (...) they use to articulate the concept of truth. Also, we argue that Husserlian truth has an advantageous position over the other concepts of truth presented. (shrink)

This article focuses on Egypt’s moment of decolonisation in order to explore some of the productive tensions between Marxism, Frantz Fanon’s work, and postcolonial contexts. Through a reading of Egypt’s attempts at independent industrialisation and decolonising ‘the international’, the article uses Frantz Fanon’s invitation to ‘stretch Marxism’ as a way of understanding the particularities of capitalism in the colonial and postcolonial world. It is posited that events such as decolonisation across the postcolonial world have been central to the evolution of (...) global capitalism, and should be centred within Marxist analyses of global politics. It is further argued that these moments can shed light on the contradictions of nationalism, sovereignty and independence, and the ways in which anticolonialism in places like Egypt ultimately reproduced, rather than challenged, colonial capitalism.

In this reading of Thus Spoke Zarathustra, I attempt to account for the gradual transformation of Zarathustra’s politics and pedagogy in light of his confrontation with a Platonic understanding of imitation. I argue that the provisional teaching of the overman is abandoned in the second half of the text because it fails to teach others to become who they are.

This study seeks to explore the major errors that frequently emerge when novice translators translate technical texts, namely legal documents released by the Department of Lands and Survey in Jordan. The goal behind this investigation is to improve legal translation training, develop students’ drafts based on the types of their mistakes, and deliver a message to curricula designers in the field of legal translation. To this end, 20 Jordanian novice translators (MA students) are chosen from two private universities to translate (...) three legal documents from Arabic into English. The main findings revealed that different problems emerged, namely the participants’ inability to translate near-synonym technical terms, grammatical problems, and stylistic problems at both lexical level and sentence level. These findings are hoped to be insightful for both learners and teachers. A number of pedagogical recommendations are proposed by the researchers to develop learners’ competence and reach a professional level and open the venue for trainers to achieve advances in the quality of the target text and in the translation teaching–learning process.

Street vendors are prominent on public streets and in traditional markets in most developing countries. They raise significant problems for public authorities, residents, pedestrians, and formal retailers. Their informal business is problematic, leading to conflicts and sometimes violence. Moreover, unlicensed street vendors employ children and women and are accused of counterfeiting and drug trading. However, they participate in reducing poverty and unemployment. The current data article aims to formulate a public perception on the problematic issue of street vending pervasiveness by (...) describing a survey dataset on street vending and its main driving factors. Street vending has traditionally be examined by linking it with one or more determinants; thus, the dataset covers poverty, lack of education, immigration, unemployment, urban culture, low-income consumption, resistance, and lack of microfinance as latent constructs. Five measurable variables are introduced that reflect each construct. All variables are measured via seven-point Likert scales. Using a Google Form, 425 responses were collected that reflect the attitudes of the general public in Baghdad, Iraq. This dataset is useful for research on socio-economic problems; more specifically, it introduces reliable measurement models for street vending and the eight factors driving it. (shrink)
