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.

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)

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.

‘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.

This article is a review of Ilham Khuri-Makdisi’s bookThe Eastern Mediterranean and the Making of Global Capitalism, 1860–1914. I argue that this book is a valuable contribution to historiographies of the Left in the Middle East, a field that remains under-represented given the importance of labour to the nationalist movements as well as broader worker-activism in the region throughout the twentieth and twenty-first centuries. I review the main debates of the book, and raise critical questions about aspects that could have (...) been probed further, among them the questions of imperialism and race in contexts such as Egypt and Lebanon, and the relationship between workers and the radical intellectuals discussed throughout the book.

This article traces Gramsci's concept of hegemony as it travels from Southern Italy to Egypt, arguing that the concept ‘stretches’, following Fanon, through an encounter with the nexus of capitalism and colonialism. I explore a reading of Gramsci's concepts in a postcolonial context, paying special attention to colonialism and anticolonialism as constitutive of the absence or presence of hegemony. Through an exploration of the Nasserist project in Egypt – the only instance of hegemony in modern Egyptian history – I show (...) how colonialism and anticolonialism were central to the formation of Nasserist hegemony. Drawing on Edward Said, I look at two particular aspects of hegemony as a traveling theory to bring to light some theoretical entanglements that arise when Gramsci travels, in turn highlighting the continuing theoretical potential thinking through such entanglements, as well as of thinking with Gramsci in Egypt and the broader postcolonial world.

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.

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.

Biases towards negative information, as well as away from positive information, are associated with psychopathology. Examining biases in multiple processes has been theorised to be more predictive than examining bias in any process alone. Anhedonia is a core symptom of psychopathology and predictive of future psychopathological symptoms. Finding that combined biases are associated with anhedonia would advance knowledge of the nature of emotional processing biases and the value of objective performance-based measures for identifying early risk markers. Participants completed tasks that (...) assess latency bias and biased recognition of emotional information, as well as an anhedonia measure. An index was computed for each task’s performance reflecting biased processing of positive and negative words. Only combined biases on both tasks were associated with anhedonia. Attentional bias was positively associated with anhedonia, but only when recognition bias for emotional words was high. Thus, assessing biases in multiple domains increased sensitivity to uncover relationships between emotional processing biases and anhedonic symptoms. (shrink)

Promoting innovative work behaviour and employee wellbeing has become essential as it endows companies with competitive advantages to thrive in today's complex business environment. This study investigates the role of workplace spirituality in inducing innovative work behaviour and employee wellbeing based on the social exchange theory and the spillover theory. It also looks at the previously unexplored mediating function of employee engagement in the relationship between workplace spirituality and the outcomes above. Additionally, it examines the interactive effect of workplace spirituality (...) and individual spirituality on employee engagement. Two waves of survey data were collected from 538 employees and their managers working in the IT sector in Pakistan. This study contributes to the expanding corpus of research on workplace spirituality, confirming that the latter positively influence innovative work behaviour and employee wellbeing. The mediating effect of employee engagement on the relationship between workplace spirituality and innovative work behaviour and employee wellbeing is also significant. Further, the results confirm that the influence of workplace spirituality on employee engagement is contingent on the degree of individual spirituality. Theoretical contributions and practical implications are discussed. (shrink)

The present study is a differential study that describes the nature of the relationship between cooperation and altruistic behavior in a sample of gifted adolescents in three universities in Egypt and Kuwait University. It also identified the differences between males/females, and senior students/junior students in both cooperation and altruism. A total of 237 gifted adolescents—with average age 21.3 ± SD 2.6 years—from three Egyptian universities: Alexandria University, Sadat Academy for Management Sciences, and Suez University, and Kuwait University, were involved in (...) this study. Measures used in the study include the Scales for Rating the Behavioral Characteristics of Superior Students, Generative Altruism Scale, and The Cooperative/Competitive Strategy Scale. Results revealed that there is a significant positive relationship between altruism and cooperation among gifted adolescents. Also, findings show that there are statistically significant differences between males and females in both altruism and cooperation. In addition, there are differences statistically significant between senior students and junior students in both altruism and cooperation in favor of senior students. It is recommended that altruism and cooperation intervention-based programs should be designed to increase the adaptive behaviors of adolescents. (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)

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 article addresses the Egyptian women's movement of the 1950s–1970s through a recent film entitled Four Women of Egypt, which focuses on the lives of four prominent Egyptian women active in the movement during that period. Using the concept of political memory, the article traces some of the major debates within the women's movement throughout this era. By focusing on the ways in which these women conceptualize the geopolitical, I show that the twin concepts of imperialism and capitalism were central (...) to the ways in which they understood gender. The result was a complex understanding of how gender intersected with Egypt's position within a broader global system of imperial capitalism. Following the transition in the 1970s to an open-market economy, the women's movement shifted away from critiques of imperialism and capitalism. This shift can be understood Primarily in terms of geopolitics, specifically the rise of neoliberalism in Egypt. New neoliberal policies had dramatic effects on the women's movement, showing why both the rise and fall of the movement must be contextualized geopolitically and transnationally. (shrink)

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)

In this paper, we present a dialectical argument for a priori skepticism (i.e. the thesis that we can be skeptical about a priori knowledge).

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 dissertation, I examine the development of autonomy in the philosophical works of Kant, Nietzsche, and Heidegger. After outlining the centrality of this development to what I call, following Robert Pippin, "philosophical modernity," I show that the figure of genius described in Kant's third Critique becomes the model for the "aesthetic" versions of autonomy articulated by Nietzsche and Heidegger under the names of "sovereignty" and "authenticity" respectively. According to these more recent formulations, autonomy is not understood as rational self-legislation, (...) but as a quasi-artistic "self-creation." Moreover, in each of these versions of aesthetic autonomy, I claim that in spite of a disavowal of mimesis understood in a Platonic sense, an implicit reliance is placed upon the operations of a "higher" sense of mimesis, a mimesis of freedom, that enables autonomy to be exemplified and, paradoxically, "imitated." For Kant, this mimesis of freedom accounts for both the continuity and discontinuity of art-historical traditions. In Nietzsche and Heidegger, however, this covert deployment of mimesis has implications for our understanding of historicity more generally, and the relationship between history and modernity in particular. After showing what these implications are, I comment on the problems and limits of "aesthetic autonomy," especially when it is understood politically or collectively, and utterly decoupled from any moral constraints.

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)

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)

While the migration of the Muslim in the U.S. dates back to the late 1800s and they have been active members of society for decades, the presence of Muslims in the U.S. has recently come under focus and discussion.

As a result of 9/11 terrorist attacks on the U.S., there has been a systematic and troubling (...) trend of violations of citizenship rights of American Muslims in general. This paper examines these violations before and after 9/11 from a historical perspective. For this purpose, Chicago, as the home of one of the largest Muslim communities in the country, is used to document and conduct this analysis. The paper also discusses the implications of these issues in terms of citizenship, race, and ethnicity. (shrink)

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. It only produces bad imitations of Zarathustra himself. I read the thought of the eternal recurrence, however, as Zarathustra’s overcoming of (...) his residual Platonic pedagogy since it challenges the mimetic relationship between master and disciple that Zarathustra originally cultivates but ultimately disavows.Dans cette présente lecture d’Ainsi parlait Zarathoustra, je tente de rendre compte de la transformation graduelle de la politique et de la pédagogie de Zarathoustra à la lumière de sa confrontation à la comprehension platonicienne de l’imitation.

Il ne fait que produire des imitations de Zarathoustra lui-même. Par eontre, je comprends la pensée de l’eternel retour comme le dépassement de sa pédagogie platonicienne résiduelle, puisque cette pensée s’oppose à la relation mimétique entre le maître et le disciple que Zarathoustra cultive au départ, mais désavoue à la fin.

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)
