Background: The castor bean is a large grassy or semi-wooden shrub or small tree. Any part of the castor plant parts can suffering from a disease that weakens the ability to grow and eliminates its production. Therefore, in this paper will identify the pests and diseases present in castor culture and detect the symptoms in each disease. Also images is showing the symptom form in this disease. Objectives: The main objective of this expert system is to obtain appropriate diagnosis of (...) the disease. Methods: In this paper, the expert system is designed for the ability of agricultural engineers to detect and diagnose disease of castor like as: seeding blight, alternaria blight, cercospora leaf spot, powdery mildew and wilt. This system presents the disease symptoms, survival and spread, favorable conditions and image for each disease. Clips and Delphi expert system languages are used for designing and implementing the proposed expert system. Results: The expert system in the diagnosis of castor diseases was assessed by farmers and agricultural engineers and they were satisfied and accepted with its quality of performance. Conclusions: The expert system is easy for farmers and people have experience in the plant of castor to detect and diagnosis the symptoms that may face this plant from several disease. (shrink)

The literature describes religious coping as an important predictor of mental well-being. Present study is aimed at extending this knowledge by assessing whether specific religious coping regulates specific cognitive emotional responses to improve well-being during Covid pandemic, an extreme international event with significant impacts on individuals and communities. A sample of young adults responded to self-report measures of negative and positive religious coping, positive reappraisal, self-blaming, and mental well-being. Results revealed that positive religious coping was a positive predictor of mental (...) well-being and positive reappraisal mediated this positive link. Also, gender and physical health status significantly interacted with positive reappraisal to predict mental well-being in these mediational associations. More specifically, indirect effects of positive reappraisal were positive and significant for men and for participants with better physical health compared with women and those with poor physical health. However, negative religious coping was not a significant correlate of mental well-being but a positive correlate of self-blame. Results suggest that positive religious coping facilitates positive regulation of emotions for improved mental well-being in young adults and particularly young men. (shrink)

The research on the dark side of leadership is still in its infancy. We have contributed to this line of research by proposing that work alienation acts as an underlying mechanism through which aversive leadership results in reduced job performance. We further propose that psychological capital acts as an important personal resource that reduces the negative effects of aversive leadership in the form of work alienation. The proposed model gets its support from the conversation of resources theory given by Hobfoll (...) (1981) which suggests that stressful situation like an aversive leadership results in the loss of employee resources as a result of that he/she indulges in work alienation and shows poor job performance to retain back the lost resources. People with better personal resources in the form of psychological capital are better able to cope-up with the aversive leader behavior and make them able to avoid work alienation. It is a time-lagged study. The data for the current study was collected from 321 employees working in the service sector organizations, particularly universities, banks and telecom organizations, through personally administered questionnaires. The results supported the mediation and moderation hypothesis. Limitations and future research along with theoretical and practical implications are given at the end. (shrink)

The precise nature of microaggression purposely obscures the exploration of the intentionality of perpetrator and the quantification of the harm committed. The act fits neatly into a system that privileges some and validates their reality to themselves and to us. This paper explores microaggression and recommends strategies for avoiding its harms.

In this narrative, Fatima examines the interplay of critical consciousness, relational dynamics, and patriarchy within social-geographical spaces. Drawing on personal experiences, the chapter explores how patriarchal norms, internalized and perpetuated within intimate relationships and community networks, shape gendered expectations and limit agency from childhood through adulthood. While acknowledging the harms inflicted by these norms, it highlights the dual role of these spaces in fostering both oppression and connection. The essay looks at why simplistic solutions like geographic escape ignore the (...) interdependence and cultural norms intrinsic to relational spaces. Instead, it advocates for a nuanced understanding of the challenges and complexities of addressing patriarchy within these contexts. Ultimately, Fatima emphasizes that the feminist struggle lies not in abandoning these spaces but in fostering critical consciousness and collective efforts to undo patriarchal systems while paying attention to the nuances of social-geographical spaces.

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)

How do we know that what has happened to us is a microaggression? I claim in this chapter that our understanding about how we perceive microaggression is grounded in the cultivation and critical reflection about experiences of people who occupy marginalized social locations. My aim is to explore the nature of epistemic harms of microaggression in order to highlight how they diminish the microaggressed’s ability to generate and participate in making knowledge claims. I differentiate between the primary (direct) harm of (...) microaggressive acts, and the secondary epistemic harms that occur in the aftermath of the microaggression, particularly when the microaggressed attempts to convey their experience to others. I conclude with an analysis of the two secondary harms in hopes that it helps us explore a possible avenue of resistance to the epistemic harms of microaggression. (shrink)

This study has proposed to apply change leadership as a vehicle forward for sustaining the growth of the tourism industry to eradicate poverty through the Pakistani tourism industry. Applying a mixed method approach, this article has attempted to uncover the role a change leader can play to help achieve the United Nations’ sustainable development goals of poverty reduction. In this study, one of the authors interviewed stakeholders of the tourism industry to find out the major drivers of the industry and (...) identify the leadership style that may prove to be effective in the said industry. In the next phase of the study, a survey method approach was used where different tourism companies and hotel chains were included for analysis. The study aimed to check employee’s perception of change leadership and its impact on their resilience and ultimately the sustainable organization performance of companies’ operationalizing in the sector with moderating impact of sustainable tourism attitude in times of a crisis. In total, 430 full-time workers in the tourism industry were contacted for a self-administered survey achieving a response rate of 83%. The findings of the study confirmed that in the presence of a change leader, the process of adaptation to sudden changing situations amidst financial crises, pandemic, and climatic change, becomes bearable and employees can cope with the work situations without pushing them to quit the industry. The study has a significant contribution toward a rapidly growing and focused industry, which can play a major role in the economy of any country leading toward job creation and poverty reduction.

Sería fácil afirmar que el objetivo de este texto es humanizar a los pájaros, concluir lecciones sobre los humanos a partir de su relación con ellos o utilizarlos como excusa para hablar de nosotros, pero Habitar como pájaro no hace nada de eso. De hecho, logra algo más minucioso, complejo y profundo: recoger sonidos y añadir opuestos. Así, el contrapunto como técnica melódica para conjugar voces es fundamental para entender el rigor y el detalle del libro, no sólo porque es (...) en sí mismo su estructura (las partes son acordes y cada capítulo tiene su acompañamiento, su siguiente sonido), sino también porque es un texto articulado a partir del discanto entre biólogos y ornitólogos, quienes han entendido (o intentado entender) a los pájaros a lo largo de la historia. Dado que el contrapunto es es- tructura y técnica, se lee un compromiso total con el cantar y el decir común. (shrink)

RESUMO Este artigo procura mostrar como a linguagem e o estilo empregados por Dostoiévski já em seu romance de estreia, Gente pobre, contribuíram para a grande inovação realizada por ele na forma literária. Ao tomar como objeto de representação a realidade prática de camadas inferiores da sociedade e adotar em sua obra uma linguagem também considerada de nível inferior, própria à maneira de se expressar dessas camadas sociais, Dostoiévski não só transcende todas as regras literárias estabelecidas como também as já (...) transgredidas até então, porque ele leva a sério não só a realidade cotidiana como a linguagem, o nível de estilo próprio a elas. Com isso ele se aproxima da representação séria e elevada da realidade cotidiana sem mudar as regras de estilo, como fizeram os franceses. O que ele muda é o ponto de vista, o foco narrativo, de um modo que não encontra precedente nem mesmo na literatura Ocidental. ABSTRACT This article seeks to show how the language and style employed by Dostoevsky since his debut novel, Poor Folk, contributed to the great innovation that he introduced into literary form. By adopting the practical reality of the lower strata of society as his object of representation and, accordingly, a low-style language, Dostoevsky transcended all established literary rules, as well as others that were already being transgressed. He took seriously both the reality of everyday life and its language, the style level proper to it. In so doing, he approached the serious and elevated representation of everyday reality without changing the rules of style, as the French did. What he changed is the point of view, the narrative focus, and he did so in a way that had no precedent even in Western literature. (shrink)

ABSTRACT This article presents an overview of the Portuguese transposition of the European Directive on Good Clinical Practice (2001/20/e) concerning scientific and academic debates on bioethics and clinical investigation. Since the Directive was transposed into Portuguese law by its National Assembly, the bureaucracy of clinical trials has been ever more complex. Despite demands for swift application processes by the Pharmaceutical industry, supported by the European Parliament, the Directive's transcription to the national law has not always delivered the expected outcome. However, (...) this has led to an increased number of applications for clinical trials in Portuguese hospitals. In this article I revise bioethical publications and decree‐laws enabling an informed appraisal of the anxieties and prospects for the implementation of the clinical trials Directive in Portugal. This article also places the European Directive in the field of sociology of bioethics, arguing that Portuguese bioethical institutions differ from those of the US, and also from Northern European counterparts. The main divergence is that those people in Portugal who claim expertise in ‘legal’ bioethics do not dominate either the bureaucratic structure of research or ethics committees for health. Even experts in the applied ethics field now claim that ‘professional bioethicists do not exist’. The recent creation of a national Ethics Committee for Clinical Investigation (CEIC) in line with the European Directive on Good Clinical Practice (GCP) will not change the present imbalance between different professional jurisdictions in the national bioethical debate in Portugal.

This paper presents the state of corporate social responsibility in Pakistan since it has been driven in the country by the Securities and Exchange Commission of Pakistan, the UN Global Compact, and trade liberalization under the WTO. This study is based on responses obtained from 51 Pakistani companies and 20 MNCs. It was found that MNCs were found to be more socially responsible to customers, to suppliers in terms of their purchasing procedures, to the environment, to their employees, to the (...) community by contributing more to the community’s education and health, and in their greater commitment to ethics. Pakistani companies need to improve their performance on CSR to gain competitive advantage. (shrink)

It is a common notion that utopias seem to gain particular relevance in a context of crisis. This may explain why, as in May 1968, social movements throughout Europe are resorting to the concept of utopia in order to respond to the current economic crisis. What seems to be at stake, now, is a changeover to a new paradigm. However, for the common citizen, the word utopia is still resonant with the vain hopes of May 1968 or with the failure (...) of the communist projects. This is why the recent publication of a special issue of the French daily evening newspaper Le Monde is so timely. Founded in 1944 and reporting a circulation of over 320,000 per issue, forty thousand of which are sold abroad, Le Monde has .. (shrink)

The selling environment is becoming more and more competitive and organizations are trying to gain edge over the other companies. Producing quality goods is not enough. In such a scenario, organizations are trying to make improvements in their salesforce which can be made by making them more ethical. Therefore, it becomes important for the organization to know the factors affecting salesforce ethical behavior. This paper makes an attempt in this regard and explores the organizational antecedents of salesforce ethical behavior. The (...) findings of the review reveal that there are various organizational factors which have an impact on salesforce ethical behavior such as compensation plan, quota, top management, code of ethics, salesforce control system, ethical climate, and ethics training. Based on the findings, the implications and directions for future research are stated. (shrink)

This study examines the dynamics of interfaith communication in modern-day Europe, emphasizing the obstacles to and opportunities presented by religious heterogeneity. The religious landscape of Europe is heterogeneous, with followers of many religions living side by side. But this variety also brings difficulties, like bias, political unrest, and resentment from the past, which can obstruct attempts to foster mutual understanding and collaboration across religious communities. Interfaith communication is essential for advancing religious freedom and social cohesiveness despite these obstacles. The research (...) was based on primary data analysis to determine whether the research used smart PLS software. It generated results that included descriptive correlation and presented a smart PLS Algorithm model between them. The research study determines interfaith communication's value, its challenges, and possible routes to religious diversity. Based on case studies and previous research, it emphasizes practical interfaith efforts and makes recommendations for legislators, religious leaders, and civil society organizations. The research found that significant interreligious Dialogue in contemporary Europe relates to religious pluralism. This article supports continuing efforts to foster tolerance, understanding, and mutual respect among Europe's varied religious groups by addressing the difficulties of interfaith interactions.

Restorativeness is defined as the potential of the environment to re-establish certain cognitive capacities related to human information processing. The most frequently used instrument for evaluating the restorativeness of places is the Perceived Restorativeness Scale, proposed by Hartig and colleagues (1991). Later on, shorter versions of the Perceived Restorativeness Scale were proposed. The aim of this work is to evaluate the discriminatory capacity of the original and of a shorter Spanish version of the PRS, considering urban settings previously selected for (...) having different level of restorativeness, according to expert’s criteria. The study involved 244 students and used a 3 x 2 mixed experimental design, with two independent variables: Restorativeness of a place (between-subjects), which was manipulated by showing pictures of settings selected with varying levels of restorativeness (high, medium, low), and length of the scale (within-subjects), which was manipulated by asking subjects to fill in both the original and a shorter version of the PRS. The order of presentation of the two scales was counterbalanced. Results show an appropriate reliability for both version of the scale. Items of being-away, fascination, and coherence of the shorter scale correlate more strongly with the corresponding factor of the original scale, compared to the others factors. Both scales produce similar values for the perceived restorativeness of the different places, except for places with low restorativeness. (shrink)

My aim in this paper is to carve out a political understanding of the Muslim identity. The Muslim identity is shaped within a religious mold. Inseparable from this religious understanding is a political one that is valuable in its own right in order to secure any sustainable possibility of participating politically as Muslims within a democratic liberal democracy, such as the United States. Here I explore not the historical or theological formation of the Muslim identity, rather a metaphysical understanding of (...) it, in order to mobilize politically while avoiding the traps of essentialism. I begin with a brief overview of the early understandings of the term “identity politics” in the United States. Moving beyond interest-based movements I explore María Lugones' particular understanding of the self as multiplicitous. I then offer examples of the Muslim identity within the context of a social movement and individualist claims, in order to draw out the political aspects of the Muslim identity. In the final section I argue that the theological criteria that define “who counts as a Muslim” is a crucial aspect of how many Muslims may understand their identity as Muslims. However, I claim that in order to avoid the traps of marginalization of Muslim minorities, one must understand oneself as a multiplicitous political agent and that, furthermore, such an understanding is not at odds with Islam or one's own understanding of their identity as Muslim.

This paper is a critique of the present mode of capitalist democracy from the ethico-moral viewpoint. The crisis of values is identified as the great bane of free market-led globalization. This trend has aggravated worldwide inequality, promoted terrorism and violence, created psychological anomie and triggered eco logical disasters. Only a few business interests in the wealthier economies are gaining at the expense of humankind. The moral dimension of the government's role has been undermined by such profit-making free market gospel. The (...) author contends that more than beingjust secular, democracy is a pre-social moral force and, as such, is perceived more proximately in the religious temper of a non-industrial society than in a mass industrial society. In the latter democracy is almost a farce with the periodic ritual of public voting as its main act. The paper castigates the global economy and global media which cleverly mastermind our lives, and pleads for a change of values which will make humans self-conscious and will restore their autonomy.

This essay is an autobiographical journey through my intellectual career. It is a reflection on how my mother tongue Berber and my identity as a woman have impacted my career to the extent that they are interlocked in my research agenda. My Berber identity inspired my graduate theses and subsequent linguistics work, and my identity as a woman inspired my endeavors to help create the first Studies and Research on Women Center and the first graduate Gender Studies Program in my (...) university. These two academic structures spearheaded the creation of similar centers and programs in Morocco and North Africa. The combination of my two identities is behind my introduction of the Language and Gender discipline in Morocco and North Africa and made of me a Berber feminist linguist. (shrink)

La pandémie de COVID-19 a eu un effet mondial. L’impact disproportionné sur les peuples autochtones et les groupes racialisés a mis les défis éthiques au premier plan dans la recherche et la pratique clinique. Au Canada, l’Énoncé de politique des trois Conseils (EPTC2), et plus particulièrement le principe de justice, met l’accent sur les soins supplémentaires à apporter aux personnes « dont les circonstances les rendent vulnérables », notamment les communautés autochtones et racialisées. En l’absence de données fondées sur la (...) race pour mesurer et éclairer la recherche en santé et la pratique clinique, nous courons le risque de causer plus de tort et de contribuer à des injustices continues. Toutefois, en l’absence d’un cadre accepté pour la collecte, la tenue à jour et la communication des données fondées sur la race au Canada, il est nécessaire d’obtenir davantage de conseils sur la façon de bien faire les choses. Il est important de noter qu’un cadre pour la collecte de données fondées sur la race devrait s’appuyer sur les directives existantes des communautés autochtones et d’autres communautés structurellement marginalisées, sur l’EPTC2, sur les recommandations de l’Organisation mondiale de la santé et sur la participation des intervenants concernés. Dans le présent document, nous décrivons des exemples historiques d’études non éthiques sur les Autochtones et les groupes racialisés, nous discutons des défis et des avantages potentiels de la collecte de données fondées sur la race, et nous concluons par les objectifs d’un cadre pancanadien visant à informer la façon dont les données fondées sur la race sont recueillies, stockées et accessibles dans la recherche en santé.

In spite of accruing concerted scholarly and managerial interest since the 1950s in corporate social responsibility (CSR), its implementation is still a growing topic as most of it remains academically unexplored. As CSR continues to establish a stronger foothold in organizational strategies, understanding its implementation is needed for both academia and industry. In an attempt to respond to this need, we carry out a systematic review of 122 empirical studies on CSR implementation to provide a status quo of the literature (...) and inform future scholars. We develop a research agenda in the form of an integrated framework of CSR implementation that pronounces its multi-dimensional and multi-level nature and provides a snapshot of the current literature status of CSR implementation. Future research avenues relating to multi-level studies, theoretically supported research models, developing economy settings, and more are recommended. Practitioners can also benefit through utilizing the holistic framework to attain a bird’s eye view and proactively formulate and implement CSR strategies that can be facilitated by collaborations with CSR scholars and experts.

In this paper, I explore the significance of an intersectional lens when it comes to our conversations surrounding the #MeToo movement, in particular the way that such a lens helps us in recognizing narratives of sexual assault and harassment that are not typically viewed as such. The mainstream discourse on #MeToo in the United States has been quite exclusionary when it comes to women who are non-dominantly situated within societal structures. In particular, this paper looks at how Muslim American women’s (...) issues surrounding sexual assault and harassment are presented as exotic and a function of their religion and culture, further narrowing what is considered worthy of attention within the discourse of the #MeToo movement. I argue that one such instance of sexual harassment that isn’t seen as such, is hijab snatching within particular contexts. Furthermore, I argue that a lack of an intersectional lens results in not only privileging certain harmful voices under the guise of inclusivity, but even when invaluable voices are allowed to enter mainstream discourse, they are often the sort that sidestep issues of Western imperialistic practices, Islamophobia, racialization of Muslims, etc. I highlight the dangers of speaking for others, especially in ways that attribute sexual violence experienced by Muslim women to their cultures and/or their men. I argue that acknowledging these dangers is in itself a crucial part of an inclusive conversation on #MeToo. (shrink)

One distinguishing feature of vertebrate oocyte meiosis is its discontinuity; oocytes are released from their prophase I arrest, usually by hormonal stimulation, only to again halt at metaphase II, where they await fertilization. The product of the c‐mos proto‐oncogene, Mos, is a key regulator of this maturation process. Mos is a serine‐threonine kinase that activates and/or stabilizes maturation‐promoting factor (MPF), the master cell cycle switch, through a pathway that involves the mitogen‐activated protein kinase (MAPK) cascade. Oocytes arrested at prophase I (...) lack detectable levels of Mos, which must be synthesized from a pool of maternal mRNAs for proper maturation. While Mos is necessary throughout maturation in Xenopus, it seems to be required only for meiosis II in the mouse. The translational activation of c‐mos mRNA at specific times during meiosis requires cytoplasmic polyadenylation. Cis‐ and trans‐acting factors for polyadenylation are, therefore, essential elements of maturation. (shrink)

There are a lot of research studies that look at "fake news" from an Arabic online source, but they don't look at what makes those fake news spread. The threat grows, and at some point, it gets out of hand. That's why this paper is trying to figure out how to predict the features that make Arabic online fake news spread. It's using Naive Bayes, Logistic Regression, and Random forest of Machine Learning to do this. Online news stories that were (...) made up were used. They are found by using Term Frequency-Inverse Document Frequency. The best partition for testing and validating the prediction was chosen at random and used in the analysis. So, all three machine learning classifications for predicting fake news in Arabic online were done. The results of the experiment show that Random Forest Classifier outperformed the other two algorithms. It had the best TF-IDF with an accuracy of 86 percent. Naive Bayes had an accuracy rate of 84%, and Logistic Regression had an accuracy rate of 85%, so they all did well. As such, the model shows that the features in TF-IDF are the most essential point about the content of an online Arabic fake news. (shrink)

In this paper I bring up some ideas on how to search for religious healing through criticism to the concepts of "belief" and "symbolic efficiency". With this purpose, its presented a brief overview of the imbrication between cure and religion in the Brazilian religious field, indicating the vitality of this relationship in the contemporary context, followed by two episodes of healing narrative in which I was personally involved. In the end, I argue that contrary to what the concept of belief (...) might suggest, therapeutic efficacy does not constitute “a discourse on" intervention on the bodies and on the world, but on the practical conditions for mobilizing the truth. The concept of belief does not constitute a good tool for understanding the diversity of implicated mediators of assemblages of healing, nor enables us to understand the intricacies of religious-therapeutic effectiveness. In anthropology, similar critique has also been made to the concept of symbolic efficacy as a conceptual tool for understanding transformations not only of "souls," but also of bodies. (shrink)

This paper argues that one of the most valuable insights that Muslim-Americans ought to bring into the political arena is our affective response to the government of the United States' internal and foreign policies regarding Muslims. I posit the concept of empathy as one such response that ought to inform our foreign policy in a manner inclusive of Muslim-Americans. The scope of our epistemic privilege encompasses the affective response that crosses borders of the nation-state in virtue of our propinquity to (...) the narratives of Muslims globally. Such an affective response is crucial to our selves remaining multiplicitous and whole. Furthermore, I argue that we ought to access and assess those aspects of our identity that make us subject to suspicions of disloyalty, because it is precisely those aspects that can inform our social and political discourse in a more morally adequate and responsive way.

This article looks at the inadequacy of space available to women in the two most holy sites for all Muslims: Masjid al-Haram in Makkah and Masjid an-Nabawi in Madinah, Saudi Arabia. I argue that religious discourse, shaped by geopolitical factors, has framed piety for women primarily in terms of modesty, such that a woman is often considered a good Muslim if she is visible only within her female community but invisible to the larger society. Furthermore, I argue that the allocation (...) of meager space affects not only the perception of women's religious standing in society, but also women's own perception about their moral selves. The article claims that by being relegated to small sections within religious spaces, women's collective worship is evident neither to the community at large nor can it be fully experienced by individual women, thus placing obstacles in women's path to seek to closeness to God.

The underlying objective of this project is to examine the ways in which the exclusionary status of Muslim-Americans remains unchallenged within John Rawls’ version of political liberalism. Toward this end, I argue that the stipulation of genuine belief in what is reasonably accessible to others in our society is an unreasonable expectation from minorities, given our awareness of how we are perceived by others. Second, using the work of Lisa Schwartzman, I show that Rawls’ reliance on abstraction of closed society (...) legitimizes the exclusion of citizens with marginal social locations. And finally, applying Charles Mills’ critique of ideal theory, I argue that Rawls’ idealization of a posture of civic friendship detracts from a discussion of equally significant societal values while sustaining existing social hierarchies.
