A sensitivity study is undertaken to characterize the impact of varying feature dimensions in emerging electronic packaging technologies. Specifically, the overall structural performance of the substrate under use conditions (thermal and combined thermomechanical loading) is investigated. The study consists of both modeling and experimental efforts. Modeling approaches are employed within the framework of a finite element code to simulate performance of different design geometry combinations in the known failure mode of solder resist layer cracking. In the models, two levels of complexity are used to better identify the impact of the individual features on the overall substrate reliability. First, local geometry is captured by including each substrate layer. Individual component geometries like microvias and PTHS are also explicitly modeled to capture synergistic failures modes. Second, more realistic non-linear material properties are used to characterize time, temperature, and rate-dependant constitutive behavior of individual substrate materials such as buildup, core, metal, etc. In the experiments, substrate warpage and reliability data is collected for validating the predictive modeling capability. From this study, directions for future design guidelines varying feature dimensions while maintaining substrate reliability are proposed.

Problem statement. It is shown that the main scientific vectors of the study of the personality image of the future can be considered philosophical, sociological, psychophysiological and psychological. In psychology, the future is revealed as a property of the mental. It is determined that the psychological phenomenology of the image of the future is that it is a holistic view of the individual about the future. It is in the mind and constantly affects behavior, activities, and its emotional state. The ability of an individual to construct his own future is due to the peculiarities of his individual psychological representations. This aspect is little studied in psychological science.  The purpose of the article is to present methods and techniques of research of representations and designing the world image of the future by the person. Results of the research. It is noted that the process of forming the image of the future is not only a vision of the end result, but also the impact on the assessment of behavior, consolidation of moral, volitional, intellectual efforts to realize their own expectations. This emphasizes the subjective nature of this process. In the framework of the research of mental representations and the peculiarities of constructing personality images of the future in a particular individual context were identified the mediative and moderative components that influence this phenomenon. The author’s method of assessing the world image of the future is presented. It is a technique of subjective scaling — that is, it shows how the individual imagines his future. To assess the relationship between the studied indicators, which are operationalized as concepts of psychosemantic analysis, a multidimensional deployment was used. Conclusions and prospects for further research. It is concluded that the psychosemantic approach is the most informative in the identified abilities of the individual to construct images of their own future. It is noted that the prospects for further research will be to identify the re lationship between forms and strategies for building mental representations of the image of the future with strategies for individual behavior in difficult life situations.

ABSTRACTGiven the increase in global positioning system enabled devices and the ubiquitous ability to connect wirelessly to information through location-based services, organizations are challenged to offer privacy-by-design support systems. Given this, we offer a conceptual framework to capture the impact of the individual component weights of concern for information privacy on behavioral intent of disclosing information. Through a sample of 217 respondents, our PLS model shows that privacy protection beliefs negatively impact concern for collection, unauthorized use, and improper access of information and that privacy risk beliefs positively impact concern for collection and existence of errors; additionally, concern for collection negatively impacts behavioral intentions to disclose information, as does concern for unauthorized use. With such detailed information, firms can address both cognitive and affective consumer concerns, enhance transparency, and communicate multiple services while handling privacy controls as an extension of those services.

This article has two purposes: (a) to examine the relationship between intercultural power relations and the widespread practice of accent discrimination and (b) to underscore the ramifications of accent discrimination both for the individual and for global society as a whole. First, authors review social theory regarding language and group identity construction, and then go on to integrate more current studies linking accent bias to sociocultural variables. Authors discuss three examples of intercultural accent discrimination in order to illustrate how this link manifests itself in the broader context of international relations (i.e., how accent discrimination is generated in situations of unequal power) and, using a review of current research, assess the consequences of accent discrimination for the individual. Finally, the article highlights the impact that linguistic discrimination is having on linguistic diversity globally, partially using data from the United Nations Educational, Scientific and Cultural Organization (UNESCO) and partially by offering a potential context for interpreting the emergence of practices that seek to reduce or modify speaker accents.

Abstract. Background: Self-esteem is a major contributor to risk for repeated suicide attempts. Prior research has shown that awareness of stigma is associated with reduced self-esteem among people with mental illness. No prior studies have examined the association between self-esteem and stereotype awareness among individuals with past suicide attempts. Aims: To understand the relationship between stereotype awareness and self-esteem among young adults who have and have not attempted suicide. Method: Computerized surveys were administered to college students (N = 637). Linear regression analyses were used to test associations between self-esteem and stereotype awareness, attempt history, and their interaction. Results: There was a significant stereotype awareness by attempt interaction (β = –.74, p = .006) in the regression analysis. The interaction was explained by a stronger negative association between stereotype awareness and self-esteem among individuals with past suicide attempts (β = –.50, p = .013) compared with those without attempts (β = –.09, p = .037). Conclusion: Stigma is associated with lower self-esteem within this high-functioning sample of young adults with histories of suicide attempts. Alleviating the impact of stigma at the individual (clinical) or community (public health) levels may improve self-esteem among this high-risk population, which could potentially influence subsequent suicide risk.

Existing research has consistently shown that perceptions of the potential economic consequences of Scottish independence are vital to levels of support for constitutional change. This paper attempts to investigate the mechanism by which expectations of the economic consequences of independence are formed. A hypothesised causal micro-level mechanism is tested that relates constitutional preferences to the existing skill investments of the individual. Evidence is presented that larger skill investments are associated with a greater likelihood of perceiving economic threats from independence. Additionally, greater perceived threat results in lower support for independence. The impact of uncertainty on both positive and negative economic expectations is also examined. While uncertainty has little effect on negative expectations, it significantly reduces the likelihood of those with positive expectations supporting independence. Overall, it appears that a general economy-wide threat is most significant, and it is conjectured that this stems a lack of information on macroeconomic governance credentials.

This book examines the impact that Athenian Old Comedy had on Greek writers of the Imperial era. It is generally acknowledged that Imperial-era Greeks responded to Athenian Old Comedy in one of two ways: either as a treasure trove of Atticisms, or as a genre defined by and repudiated for its aggressive humor. Worthy of further consideration, however, is how both approaches, and particularly the latter one that relegated Old Comedy to the fringes of the literary canon, led authors to engage with the ironic and self-reflexive humor of Aristophanes, Eupolis, and Cratinus. Authors ranging from serious moralizers (Plutarch and Aelius Aristides) to comic writers in their own right (Lucian, Alciphron), to other figures not often associated with Old Comedy (Libanius) adopted aspects of the genre to negotiate power struggles, facilitate literary and sophistic rivalries, and provide a model for autobiographical writing. To varying degrees, these writers wove recognizable features of the genre (e.g., the parabasis, its agonistic language, the stage biographies of the individual poets) into their writings. The image of Old Comedy that emerges from this time is that of a genre in transition. It was, on the one hand, with the exception of Aristophanes’s extant plays, on the verge of being almost completely lost; on the other hand, its reputation and several of its most characteristic elements were being renegotiated and reinvented.

Based on an analysis of the marginal markings and annotations Nietzsche made to the works of Emerson in his personal library, the book offers a philosophical interpretation of the impact on Nietzsche’s thought of his reading of these works, a reading that began when he was a schoolboy and extended to the final years of his conscious life. The many ideas and sources of inspiration that Nietzsche drew from Emerson can be organized in terms of two main lines of thought. The first line leads in the direction of the development of the individual personality, that is, the achievement of critical thinking, moral autonomy, and original self-expression. The second line of thought is the overcoming of individuality: that is to say, the need to transcend one’s own individual—and thus by definition limited—view of the world by continually confronting and engaging with visions different from one’s own and by putting into question and debating one’s own values and certainties. The image of the strong personality that Nietzsche forms thanks to his reading of Emerson ultimately takes on the appearance of a nomadic subject who is continually passing out of themselves—that is to say, abandoning their own positions and convictions—so as to undergo a constant process of evolution. In other words, the formation of the individual personality takes on the form of a regulative ideal: a goal that can never be said to have been definitively and once and for all attained.

This active learning exercise is designed to deconstruct the impact of social determinants through the assumption of randomly selected personas. As an active learning exercise, it provides opportunities for discussion, problem solving, writing, and synthesis, while incorporating multiple learning style preferences. Part 1 involves assessing the individual social determinants at work. Part 2 involves exploring ways said determinants can enhance community health through collaboration. Assumption of personas unlike one’s own facilitates an open discussion of social position and ranges of factors influential to health without potentially evoking a sense of defensiveness associated with personal privilege (or the lack thereof).

The epidemiology and the current burden of chronic liver disease are changing globally, with non-alcoholic fatty liver disease (NAFLD) becoming the most frequent cause of liver disease in close relationship with the global epidemics of obesity, type 2 diabetes and metabolic syndrome. The clinical phenotypes of NAFLD are very heterogeneous in relationship with multiple pathways involved in the disease progression. In the absence of a specific treatment for non-alcoholic steatohepatitis (NASH), it is important to understand the natural history of the disease, to identify and to optimize the control of factors that are involved in disease progression. In this paper we propose a critical analysis of factors that are involved in the progression of the liver damage and the occurrence of extra-hepatic complications (cardiovascular diseases, extra hepatic cancer) in patients with NAFLD. We also briefly discuss the impact of the heterogeneity of the clinical phenotype of NAFLD on the clinical practice globally and at the individual level.
