ABSTRACTNon-equilibrium Green’s functions (NEGF) simulations are carried out to determine the impact of an unintentional dopant in the middle of the channel of a FinFET. We consider two different geometries scaled according to the ITRS and two different types of dopants, donors and acceptors. We show that there is a degradation of the subthreshold characteristics with the scaling of the smooth device and also a stronger impact of the stray dopants in the middle of the channel, with variations up to 32% in the current in on-state conditions.

The Impact

This book provides an account of how and why routine interactions break down and how such situational breakdowns lead to protest violence and other types of surprising social outcomes. It takes a close-up look at the dynamic processes of how situations unfold and compares their role to that of motivations, strategies, and other contextual factors. The book discusses factors that can draw us into violent situations and describes how and why we make uncommon individual and collective decisions. Covering different types of surprise outcomes from protest marches and uprisings turning violent to robbers failing to rob a store at gunpoint, it shows how unfolding situations can override our motivations and strategies and how emotions and culture, as well as rational thinking, still play a part in these events. The first chapters study protest violence in Germany and the United States from 1960 until 2010, taking a detailed look at what happens between the start of a protest and the eruption of violence or its peaceful conclusion. They compare the impact of such dynamics to the role of police strategies and culture, protesters’ claims and violent motivations, the black bloc and agents provocateurs. The analysis shows how violence is triggered, what determines its intensity, and which measures can avoid its outbreak. The book explores whether we find similar situational patterns leading to surprising outcomes in other types of small- and large-scale events: uprisings turning violent, such as Ferguson in 2014 and Baltimore in 2015, and failed armed store robberies.

Chapter 09 Nonequilibrium Green’s functions (NEGF), including coupled-correlated (C) single- and multi-particle Green’s functions, are defined as averages weighted with the time-development operator U(t0+τ,t0). Linear conductivity is exhibited as a two-particle equilibrium Green’s function (Kubo-type formulation). Admitting particle sources (S:η,η+) and non-conservation of number, the non-equilibrium multi-particle Green’s functions are constructed with numbers of creation and annihilation operators that may differ, and they may be derived as variational derivatives with respect to sources η,η+ of a generating functional eW=TrU(t0+τ,t0)CS/TrU(t0+τ,t0)C. (In the non-interacting case this yields the n-particle Green’s function as a permanent/determinant of single-particle Green’s functions.) These variational relations yield a symmetric set of multi-particle Green’s function equations. Cumulants and the Linked Cluster Theorem are discussed and the Random Phase Approximation (RPA) is derived variationally. Schwinger’s variational differential formulation of perturbation theories for the Green’s function, self-energy, vertex operator, and also shielded potential perturbation theory, are reviewed. The Langreth Algebra arises from analytic continuation of integration of products of Green’s functions in imaginary time to the real-time axis with time-ordering along the integration contour in the complex time plane. An account of the Generalized Kadanoff-Baym Ansatz is presented.

The Impact

Abstract Scholars have long debated whether populism harms or improves the quality of democracy. This article contributes to this debate by focusing on the impact of populist parties in government. In particular, it inquires: (1) whether populists in government are more likely than non-populists to negatively affect the quality of democracies; (2) whether the role of populists in government matters; and (3) which type of populism is expected to negatively affect the quality of liberal-democratic regimes. The results find strong evidence that the role of populists in government affects several qualities of democracy. While robust, the findings related to (2) are less clear-cut than those pertaining to (1). Finally, regardless of their role in government, different types of populism have different impacts on the qualities of democracy. The results show that exclusionary populist parties in government tend to have more of a negative impact than other forms of populism.

The Impact

There is evidence that greater aesthetic experience can be linked to artworks when their corresponding meanings can be successfully inferred and understood. Modern cultural-expo architecture can be considered a form of artistic creation and design, and the corresponding design philosophy may be derived from representational objects or abstract social meanings. The present study investigates whether cultural-expo architecture with an easy-to-understand architectural appearance design is perceived as more beautiful and how architectural photographs and different types of descriptions of architectural appearance designs interact and produce higher aesthetic evaluations. The results showed an obvious aesthetic preference for cultural-expo architecture with an easy-to-understand architectural appearance design (Experiment 1). Moreover, we found that the aesthetic rating score of architectural photographs accompanied by an abstract description was significantly higher than that of those accompanied by a representational description only under the difficult-to-understand design condition (Experiment 2). The results indicated that people preferred cultural-expo architecture with an easy-to-understand architectural appearance design due to a greater understanding of the design, providing further evidence that abstract descriptions can provide supplementary information and explanation to enhance the sense of beauty of abstract cultural-expo architecture.

Abstract Compared to men, women undertake more family caregiving responsibilities, and thus take more toll in health and wellbeing when they are employed. The current study examined the gender difference in mental health among employed family caregivers, focusing on the role of workplace support in balancing work and caregiving roles. Guided by the social role theory and the moderated-mediation model of employment adjustment and mental health, we analyzed a nationally representative data from the 2012 Canada General Social Survey - Caregiving and Care Receiving with a sample of 2,426 participants selected. Moderated-mediation analysis based on the SPSS macro PROCESS 3.3 was used. Women employed family caregivers are more likely to undertake higher intensive caregiving, make more employment adjustment, and further report worse mental health status than their men counterparts. Gender difference was apparent in regards to the workplace support. For women, the moderating effect of workplace support is significant only when there are at least 5 different types of workplace support available at their workplaces, while for men, the moderating effect is significant when there are at least 2-3 different types of workplace support available. Women employed family caregivers experience worse mental health when employment adjustment is needed for their care responsibility. Findings have implications for providing workplace support for family caregivers given that women benefit less from workplace support compared to men. Further study is needed to explore the impact of various types of workplace support for women employed family caregivers, and to provide tailored support to them.

Academic Year

This research aimed to investigate and compare teachers’ conceptualizations of their students’ and their own outcomes of our earlySTEM program at the K4 level in two distinct roles: practitioners only and practitioners and program developers jointly. The study group included 66 teachers, 26 of whom had actively contributed to the development of the earlySTEM program. Teachers in both roles were supported by teacher guides, student books and workshops throughout the 8-month long academic year. Data was collected at the end of the academic year through an open-ended survey. The program developer teachers identified more student outcomes under more diverse categories while the practitioner teachers mainly concentrated on cognitive outcomes and limited their conceptualizations to the national curriculum. In addition, the program developer teachers valued their involvement in the program development process and expressed more diverse professional outcomes referring to different types of teacher knowledge.

AbstractTumours are complex ecosystems composed of different types of cells that communicate and influence each other. While the critical role of stromal cells in affecting tumour growth is well established, the impact of mutant cancer cells on healthy surrounding tissues remains poorly defined. Here, we uncovered a paracrine mechanism by which intestinal cancer cells reactivate foetal and regenerative Yap-associated transcriptional programs in neighbouring wildtype epithelial cells, rendering them adapted to thrive in the tumour context. We identified the glycoprotein Thrombospondin-1 (Thbs1) as the essential factor that mediates non-cell autonomous morphological and transcriptional responses. Importantly, Thbs1 is associated with bad prognosis in several human cancers. This study reveals the Thbs1-YAP axis as the mechanistic link mediating paracrine interactions between epithelial cells, promoting tumour formation and progression.

The chapter documents the growth of economic relations between China and Sub-Saharan Africa (SSA), focussing on trade, foreign direct investment, Chinese construction and engineering projects, loans, and aid. The chapter highlights the way in which these are sometimes combined in resources-for-infrastructure deals. It shows the variety of different actors involved in these relationships, including state and non-state actors, on both the Chinese and African sides. It then discusses the role of strategic diplomatic, strategic economic, and commercial objectives in the growing Chinese involvement in SSA. It also addresses questions of African agency and the interests of African actors in economic relations with China. The impact of political, strategic economic and commercial factors on different types of economic relations is then analyzed econometrically.
