This article analyses discussions between representatives of three schools in the theory of international relations - realism, liberalism and constructivism - on the driving factors of nuclear proliferation. The paper examines major theoretical approaches, outlined in the studies of Russian and foreign scientists, to the causes of nuclear weapons development, while unveiling their advantages and limitations. Much of the article has been devoted to alternative approaches, particularly, the role of mathematical modeling in assessing proliferation risks. The analysis also reveals a variety of different approaches to nuclear weapons acquisition, as well as the absence of a comprehensive proliferation theory. Based on the research results the study uncovers major factors both favoring and impeding nuclear proliferation. The author shows that the lack of consensus between realists, liberals and constructivists on the nature of proliferation led a number of scientists to an attempt to explain nuclear rationale by drawing from the insights of more than one school in the theory of IR. Detailed study of the proliferation puzzle contributes to a greater understating of contemporary international realities, helps to identify mechanisms that are most likely to deter states from obtaining nuclear weapons and is of the outmost importance in predicting short- and long-term security environment. Furthermore, analysis of the existing scientific literature on nuclear proliferation helps to determine future research agenda of the subject at hand.

<p>Bullying has gained a lot of attention in the public and academic spheres over the past two decades (Carrera, DePalma, & Lameiras, 2011; Monks et al., 2009) and is considered to be a very serious international issue (Due et al., 2005; Mullis, Martin, Foy, & Arora, 2012). There is extensive research based on the experiences of bullying, which has examined prevalence rates (Green, Harcourt, Mattioni, & Prior, 2013), distinctions between different types of bullying (Rivers & Smith, 1994; Smokowski & Kopasz, 2005) as well as the short and long term impacts (Coggan, Bennett, Hooper, & Dickinson, 2003). Through this, a strong research based understanding of bullying has been developed and a consistent definition established (Canty, Stubbe, Steers, & Collings, 2014; Carroll-Lind, 2009). However, previous research has primarily focused on the experiences of bullying, and few studies have examined how bullying is understood from the perspectives of young people. The present study aimed to bridge this gap by exploring young people’s understanding of bullying behaviour in New Zealand. Twenty participants completed a short questionnaire and structured interview, where they discussed four hypothetical scenarios, each describing a different type of bullying in a different setting. Results demonstrated that young people maintain a much broader conception of bullying than what is currently defined by academia. The academic criteria of intention to harm, repetition and an imbalance of power were not central to young people’s definitions of bullying. Rather, factors such as, the reaction of the victim, how public the behaviour was and the role of friendship were more instrumental in shaping young people’s bullying perceptions and definitions. Furthermore, it was found that the perceived relationship between bullies, victims and bystanders as well as gender differences, also influenced participants’ understanding of bullying behaviours. These findings yield important implications for the development and efficacy of intervention programs. Limitations and avenues of future research are also discussed.</p>

Severe disability is an important predictor of nursing home admissions. The purpose of this study is to examine the role of severe disability pacing on risk of short- and long-term nursing home stays. Respondents who developed severe disability were assigned into one of two pacing trajectories: catastrophic or progressive disability. The author analyzed seven waves of data from the Health and Retirement Study and created a series of discrete-time event history models. The analysis showed that the risk associated with severe disability and nursing home stays varied based on severe disability pacing. Progressive and catastrophic disability were associated with increased risk of short- and long-term stays; however, the risk of nursing home stays was much greater for respondents with catastrophic disability for short- and long-term stays. The findings have implications for policy and research. The author suggests that future research focus on interventions aimed at slowing the pace of severe disability.

The issue addressed relates to an area of 1891694 ha of which 1183343 ha are agricultural land (62, 56) located in the south-west of Romania and refer to the use of soil chemical and physical properties as an acceptor for certain crop systems, with minimal undesirable effects both for plants to be grown, as well as soil characteristics and groundwater surface quality. It is therefore necessary on a case-by-case basis, measure stoc or rect the acidic reaction by periodic or alkaline calculations, the improvement of plant nutrition conditions through ameliorative fertilization and the application of measures to improve the physical state, sufficient justification for the need to develop short and long term strategies for the protection and conservation of edifying factors and the need to respect the frequency of field and laboratory investigations at all 8x8 km grids of the National Soil-Grounds Monitoring System (organized by I.C.P.A.) and completing it with the relevant pedological and agrochemical studies.

Epidemiologic studies suggest that the lifetime prevalence of bipolar spectrum disorders ranges from 2.8 to 6.5 percent of the population. To decrease morbidity and mortality associated with disease progression, pharmacologic intervention is indicated for the majority of these patients. While a number of effective treatment regimens exist, many conventional medications have significant side effect profiles that adversely impact patients’ short and long-term well-being. It is thus important to continue advancing and improving therapeutic options available to patients. This paper reviews the limitations of current treatments and examines the chemical compound Linalool, an alcohol found in many plant species, that may serve as an effective mood stabilizer. While relatively little is known about Linalool and bipolar disorder, the compound has been shown to have antiepileptic, anti-inflammatory, anxiolytic, anti-depressive, and neurotrophic effects, with mechanisms that are comparable to current bipolar disorder treatment options.

Although psychologists typically see creativity as an individual-level event, sociologists and cultural anthropologists are more likely to view it as a sociocultural phenomenon. This phenomenon takes place at the level of relatively large and enduring collectives, such as cultures, nations, and even whole civilizations. This chapter reviews the extensive research on such macro-level creativity. The review begins with a historical overview before turning to the cross-sectional research on the creative Ortgeist, a subject that encompasses the factors that influence the relative creativity of both preliterate cultures and entire modern nations. From there the chapter turns to role of the Zeitgeist in affecting the creativity of civilizations across time—the rise and fall of creative activity. This research examines both quantitative and qualitative causes that operate both short- and long-term.

This chapter examines the development and politics of US energy policy, with an emphasis on three themes: the distribution of authority to regulate energy between national (or federal) and subnational governments, the relationship between energy and environmental policy and regulation, and the role of climate action in energy politics. It reviews patterns of energy production and consumption; provides an overview of national energy politics; and reviews literatures on federalism and energy politics and policy, the increasing integration of energy and environmental policies, and the politics of energy and climate action. The chapter concludes with a discussion of a future research agenda that underscores the significance of political polarization, subnational governance, and technological innovation for understanding US energy policy.

Bottom of the Pyramid (BoP) organizations are the ones that develop a set of capabilities that contribute to create short- and long-term sustainability values inside and outside the boundaries of BoP ecosystems. Capabilities have an important role in BoP organizations’ strategies that aim to solve BoP issues. Notwithstanding its developments, BoP research still lacks theoretical contributions for the analysis of organizations. We suggest special attention to the need of advancing knowledge on capabilities of BoP organizations because this field is scattered and fragmented, misinterpreted, and still underdeveloped in the literature. We oriented our research formulating and seeking answers to our main question on what are the capabilities needed to enable organizations to create sustainability values in BoP ecosystems? We conducted an integrative review of BoP research for the period from 1998 to 2019, and we found 22 key capabilities of BoP organizations. We organized the capabilities into four major categories including BoP Responsible Consumption, BoP Responsible Business Model, BoP Responsible Management, and BoP Responsible Innovation. We advanced propositions and discussions regarding the capabilities and major categories’ popularity, interdependence and combination, short- and long-term temporal functions, sustainability roles, and effectiveness to address BoP issues. Our article organizes the field of capabilities of BoP organizations; advances contributions and implications for management, organizations, and policymaking; and opens fruitful avenues for future research.

In recent years, the role of human microbiota as a short- and long-term health promoter and modulator has been affirmed and progressively strengthened. In the course of one’s life, each subject is colonized by a great number of bacteria, which constitute its specific and individual microbiota. Human bacterial colonization starts during fetal life, in opposition to the previous paradigm of the “sterile womb”. Placenta, amniotic fluid, cord blood and fetal tissues each have their own specific microbiota, influenced by maternal health and habits and having a decisive influence on pregnancy outcome and offspring outcome. The maternal microbiota, especially that colonizing the genital system, starts to influence the outcome of pregnancy already before conception, modulating fertility and the success rate of fertilization, even in the case of assisted reproduction techniques. During the perinatal period, neonatal microbiota seems influenced by delivery mode, drug administration and many other conditions. Special attention must be reserved for early neonatal nutrition, because breastfeeding allows the transmission of a specific and unique lactobiome able to modulate and positively affect the neonatal gut microbiota. Our narrative review aims to investigate the currently identified pre- and peri-natal factors influencing neonatal microbiota, before conception, during pregnancy, pre- and post-delivery, since the early microbiota influences the whole life of each subject.
