Contemporary evolutionary biology comprises a plural landscape of multiple co-existent conceptual frameworks and strenuous voices that disagree on the nature and scope of evolutionary theory. Since the mid-eighties, some of these conceptual frameworks have denounced the ontologies of the Modern Synthesis and of the updated Standard Theory of Evolution as unfinished or even flawed. In this paper, we analyze and compare two of those conceptual frameworks, namely Niles Eldredge’s Hierarchy Theory of Evolution (with its extended ontology of evolutionary (...) entities) and the Extended Evolutionary Synthesis (with its proposal of an extended ontology of evolutionary processes), in an attempt to map some epistemic bridges (e.g. compatible views of causation; niche construction) and some conceptual rifts (e.g. extra-genetic inheritance; different perspectives on macroevolution; contrasting standpoints held in the “externalism–internalism” debate) that exist between them. This paper seeks to encourage theoretical, philosophical and historiographical discussions about pluralism or the possible unification of contemporary evolutionary biology. (shrink)

The current study is a pilot trial to examine the effects of a nonelective, classroom-based, teacher-implemented, mindfulness meditation intervention on standard clinical measures of mental health and affect in middle school children. A total of 101 healthy sixth-grade students (55 boys, 46 girls) were randomized to either an Asian history course with daily mindfulness meditation practice (intervention group) or an African history course with a matched experiential activity (active control group). Self-reported measures included the Youth Self Report (YSR), a modified (...) Spielberger State-Trait Anxiety Inventory, and the Cognitive and Affective Mindfulness Measure –Revised. Both groups decreased significantly on clinical syndrome subscales and affect but did not differ in the extent of their improvements. Meditators were significantly less likely to develop suicidal ideation or thoughts of self-harm than controls. These results suggest that mindfulness training may yield both unique and non-specific benefits that are shared by other novel activities. (shrink)

Mindfulness training has been used to improve emotional wellbeing in early adolescents. However, little is known about treatment outcome moderators, or individual differences that may differentially impact responses to treatment. The current study focused on gender as a potential moderator for affective outcomes in response to school-based mindfulness training. Sixth grade students (N = 100) were randomly assigned to either the six weeks of mindfulness meditation or the active control group as part of a history class curriculum. Participants in the (...) mindfulness meditation group completed short mindfulness meditation sessions four to five times per week, in addition to didactic instruction (Asian history). The control group received matched experiential activity in addition to didactic instruction (African history) from the same teacher with no meditation component. Self-reported measures of emotional wellbeing/affect, mindfulness, and self-compassion were obtained at pre and post intervention. Meditators reported greater improvement in emotional wellbeing compared to those in the control group. Importantly, gender differences were detected, such that female meditators reported greater increases in positive affect compared to females in the control group, whereas male meditators and control males displayed equivalent gains. Uniquely among females but not males, increases in self-reported self-compassion were associated with improvements in affect. These findings support the efficacy of school-based mindfulness interventions, and interventions tailored to accommodate distinct developmental needs of female and male adolescents. (shrink)

West Nile virus (WNV) is a mosquito-borne flavivirus that was first identified in 1937 in the West Nile district of Uganda. The virus is now widely distributed throughout the world and is considered a significant public health concern. WNV is primarily transmitted to humans through the bite of infected mosquitoes, with birds serving as the primary reservoir host. Most people infected with WNV will not experience any symptoms, but approximately 1 in 5 will develop a fever, and a smaller percentage (...) may develop more severe symptoms such as meningitis or encephalitis. There is no specific treatment for WNV infection, and prevention efforts focus on mosquito control measures and personal protective measures to avoid mosquito bites. While WNV is not typically considered a major threat to human health, outbreaks have occurred sporadically in various parts of the world, and ongoing surveillance and research are necessary to better understand and control the virus. Objectives: This paper will solve the problems of treatment of West Nile virus (WNV) through correct diagnosis and treatment. Methods: In this research, we provide an expert system for the diagnosis of West Nile virus (WNV) which will help doctors to explore everything related to the problems of West Nile virus (WNV). We look forward to providing simplified answers to West Nile virus (WNV). (shrink)

A fundamental fact is “pure” just in case it has no grounded entities—ex. Tokyo, President Biden, the River Nile, {Socrates}, etc.—among its constituents. Purity is the thesis that every fundamental fact is pure. I argue that Purity is false. My argument begins with a familiar conditional: if Purity is true, then there are no fundamental “grounding facts” or facts about what grounds what. This conditional is accepted by virtually all of Purity’s defenders. However, I argue that it is also the (...) first step toward Purity’s undoing. For, if every grounding fact has a ground, then some grounded entities have “groundmates” or distinct grounded entities that share their full grounds. But, if there are groundmates, then Purity is false. So Purity leads to a contradiction. Therefore, it is false. I close by noting that my argument against Purity also gives us a powerful reason to think that some grounding facts are fundamental. (shrink)

The Predynastic Period in Ancient Egypt is the time before recorded history from the Paleolithic to the Neolithic Age and on to the rise of the First Dynasty and is generally recognized as spanning the era from c. 6000-3150 BCE (though physical evidence argues for a longer history). While there are no written records from this period, archaeological excavations throughout Egypt have uncovered artifacts which tell their own story of the development of culture in the Nile River Valley. The periods (...) of the Predynastic Period are named for the regions/ancient city sites in which these artifacts were found and do not reflect the names of the cultures who actually lived in those areas. The Predynastic Period was given its name in the early days of archaeological expeditions in Egypt before many of the most important finds were discovered and catalogued which has led some scholars to argue over when, precisely, the Predynastic Period begins and, more importantly, ends. These scholars suggest the adoption of another designation, 'Protodynastic Period', for that span of time closer to the Early Dynastic Period (c. 3150-2613 BCE) or 'Zero. (shrink)

The problem of non-acceptance of philosophy in Arab Culture is a complex one and it is worthy of study and analysis. This problem relates to the nature of the composition of Arab Culture on the one hand, and that of philosophy itself on the other. With reference to the composition of Arab culture, there are numerous contributory elements that inform Arab culture today; some of which are Arabic in and others of which are foreign and only came to the Arab (...) habitat lands since the arrival of the Islamic religion. Arab culture is derived from a rich history comprising a number of Arab states that produced a multi-faceted and resplendent civilization, extending from Mesopotamia to the Nile Delta and Saba and Hamer. All of these independent civilizations contributed to Arab culture. In addition, Islam has also made a significant contribution towards polishing and entering all cultures before and after it extended throughout the world. In Arabic culture a critical trend arose in opposition to philosophy, contradicting the pattern in former Arabic civilizations, it is based on political religion as a foundation from which to attack and destroy philosophy. The second factor linked to the unaccepted nature of philosophy in Arab culture originates from philosophy itself. As is known by philosophers, the originality and creativity of philosophy first manifested in Ancient Greece. Moreover, the Greeks differed from other nations in many respects. For instance; 1) Multiplicity of religions, law and social system. 2) Political system, they created the first pattern of democracy in the world, which became the most basic of all democratic systems. 3) Social structure consisting of Whites, Slaves and Barbarians. 4) Customs and traditions, they have different views regarding women, slavery, citizenship and freedom of though. 5) Also the Greek nation differs from other nations in the high number of philosophical scholars that emerged during its 1200 year era of civilization. This research will analyze both the nature of contemporary Arabic Culture and the tradition of Greek Philosophy to ascertain the factors informing the unacceptability of Greek Philosophy in Arabic Culture.

The problem of unaccepted philosophy in Arab Culture is a complex problem and its deserve to study and analyze. This problem is returned to the nature of composing of Arab Culture from one hand, and to the philosophy itself on the other hand. On composing of Arab culture, there are a numerous of elements contribute to composing Arab culture, some of them are Arabic origin and others are foreign, and came to Arab habitat before and after of the Islamic realign. (...) By the way, the Arab Island is not alone which produce the Arab culture but there were Arab states produced a resplendent civilization such as civilization of Mesopotamia , Nile civilization and Saba & Hamer. All of these civilizations contributed to build Arab culture. In addition that, Islam religion have a great contribute on polishing and culturing all the cultures before and after his extended on the world. In Arabic culture there was a critical trend raised against the philosophy. It was modern trend compared with the history of Arab culture that returned to thousands of years BC. This critical trend used political religion to refusing philosophy. The second factor for unaccepted philosophy in Arab culture comes from philosophy itself. As known between philosophers that, the originality and creativity of philosophy came from its Greek background. Moreover, the Greeks differ from other nations in many aspects. For instance, 1) Multiplicity of religions, law and social system. 2) Political system, they create the first pattern of democracy in the world which become the basic of all democracies systems. 3) Social structure consists of White, Slaves and Barbarians. 4) Customs and traditions, they have different view to women, Slaves, citizenship and freedom of thinking. 5) Also Greek nation differs from other nations by the high number of philosophy scholars during the 1200 years of civilization age. This research will analysis two reason (Arabic Culture & Greek Philosophy) to conclude the factors behind the unaccepted of Greek Philosophy in Arabic Culture. (shrink)

Recent scholarship on climate and conflict has increasingly examined the dynamic relationship between environmental scarcities and geopolitical tensions. Overall, climate-related shocks often lead to escalated disputes over natural resources, thus positioning climate hazards not only as an environmental issue but also as a catalyst that intensifies existing geopolitical and social frictions. The discourse on climate and conflict has mostly centred on its direct effects on natural resources and environmental conditions. However, its role in precipitating conflicts underscores the critical need to (...) incorporate climate considerations within broader security and policy frameworks. In recent decades, one of the most compelling developments in this field is the inclusion of environmental issues within the security paradigm. Environmental degradation, global warming, and climate change are now recognized as critical threats that transcend national borders, impacting personal, national, and international security . These factors have broadened our comprehension of the relationships among environmental transformation, conflict, and vulnerability, and have highlighted the importance of conservation and sustainable development in fostering peace, stability, and human security. Despite the increased attention on climate in conflict and security studies, the mechanisms through which an environmental catastrophe, or the threat of it, gets securitized in conflict remain under investigated. Understanding how these threats are framed and leveraged by conflicting parties can provide critical insights into the intersection of environmental risks and geopolitical strategies, thereby enriching the discourse on environmental security and conflict dynamics. Most case studies focus on the securitization of natural resources, such as water in the Nile and Indus basins, concentrating on resource scarcity rather than potential catastrophes. Additionally, research on the Israeli-Palestinian conflict and domestic politics in the United Kingdom and the Netherlands shows how framing environmental threats as national security issues can influence power dynamics and foster global action. However, these cases suggest that previous research has predominantly investigated how states strategically employ environmental narratives within the framework of national security for political and economic advantages, often in contexts removed from direct conflict scenarios. Moreover, much of the discussion on environmental securitization has focused on state-centric perspectives and inter-state conflicts. This emphasis on state actions, both in domestic and international arenas, has left a significant gap concerning the weaponization of environmental threats by non-state actors within ongoing conflicts. In that sense, the contribution of my thesis is twofold. First, it analyzes the weaponization of a looming environmental catastrophe within a conflict setting. Second, it focuses on a case where non-state actors, specifically the Houthis, are primary securitization actors. More specifically, my thesis addresses the existing gap in the literature by analysing the case of the FSO Safer, a deteriorating oil storage tanker moored off the coast of Yemen. Before the United Nations’ successful offloading plan, the tanker held over one million barrels of crude oil, posing a significant risk of massive ecological and economic damage due to its poor condition and lack of maintenance since the onset of the Yemeni conflict. Despite the imminent threat of an ecological disaster, the conflicting parties in Yemen – the Houthis and the internationally recognized government – have used the Safer as a bargaining chip rather than prioritizing immediate remedial action. This has put the entire region in a state of suspense, with the potential for disastrous oil leakage that could impact the Red Sea's marine ecosystems and the broader geopolitical stability. The FSO Safer crisis has directly inspired the research question of this study, highlighting the need to understand the strategic use of environmental threats in geopolitical conflicts. This crisis vividly illustrates how impending ecological disasters are not solely managed as environmental or humanitarian issues but are intricately woven into the fabric of international security and conflict negotiation strategies. It prompts critical inquiries into how and why such existential threats are leveraged by involved parties to advance their geopolitical agendas. Therefore, the research question formulated for this study is: How are environmental threats utilized as strategic tools in geopolitical conflicts? (shrink)
