In this paper we present a simple technique to derive certificates of non-realizability for a combinatorial polytope. Our approach uses a variant of the classical algebraic certificates introduced by Bokowski and Sturmfels (1989), the final polynomials. More specifically we reduce the problem of finding a realization to that of finding a positive point in a variety and try to find a polynomial with positive coefficients in the generating ideal (a positive polynomial), showing that such point does not exist. Many, if not most, of the techniques for proving non-realizability developed in the last three decades can be seen as following this framework, using more or less elaborate ways of constructing such positive polynomials. Our proposal is more straightforward as we simply use linear programming to exhaustively search for such positive polynomials in the ideal restricted to some linear subspace. Somewhat surprisingly, this elementary strategy yields results that are competitive with more elaborate alternatives, and allows us to derive new examples of non-realizable combinatorial polytopes ; Gouveia was partially supported by the Centre for Mathematics of the University of Coimbra - UIDB/00324/2020 , funded by the Portuguese Government through FCT/MCTES .

Abstract –In 2025 per capita water availability will decrease to 150 gallons per day in the best for the communities near any aquifer.The water situation will worsen as the population density and the shortage becomes acute exacerbate unsafe, leading cause of death in children with hydrotransmitted diseases.Such a scenario requires theoretical reconceptualization enabling public policies, environmental agendas, public opinion and social work.In this sense, the objective of this paper is to present water situation to conceptualize from the thought of Enrique Leff (2002, 2004, 2008) and analyze their transformation into public agenda.Understanding the relationship between water situations, public opinion, political initiatives, scientific diagnoses, technohydrological innovations and media coverage will be critical for social work professionals in the near future. Keywords –Sustainability, Access, Knowledge and Rationality Agenda. ; ESPECIFICAÇÃO DE UM MODELO PARA ESTUDO DA SUSTENTABILIDADE DO TRABALHO SOCIAL Resumo - Em 2025, a disponibilidade de água per capita diminuirá para 150 galões por dia, no melhor para as comunidades próximas a qualquer aqüífero. A situação da água vai piorar à medida que a densidade populacional e a escassez se agravam de forma aguda e insegura, principal causa de morte em crianças com doenças hidrotransmitidas. Tal cenário requer uma reconceituação teórica viabilizando políticas públicas, agendas ambientais, opinião pública e trabalho social. Nesse sentido, o objetivo deste artigo é apresentar a situação da água para conceituar a partir do pensamento de Enrique Leff (2002, 2004, 2008) e analisar sua transformação em agenda pública. Compreender a relação entre situações hídricas, opinião pública, iniciativas políticas, diagnósticos científicos, inovações tecnohidrológicas e cobertura da mídia será fundamental para os profissionais do serviço social em um futuro próximo.

Social inequalities fuel a debate about the meaning of political equality. Formal procedural equality is criticised for reproducing discriminatory outcomes against disadvantaged groups but affirmative action, particularly in the form of group quotas, is also contested. When opposing conceptions of substantive equality support divergent views about which procedural rule genuinely respects political equality, democracies cannot identify a standard or rule of procedural fairness to be widely accepted as fair. This dispute over procedural fairness can carry on indefinitely and could challenge democracy's legitimacy claim. I argue that democracies can renew their legitimacy claim by embracing this debate and by accommodating it through constitutional deliberation that must be as impartial and meaningful as possible. Impartiality ideally requires the presence of every citizen in this process because each of them has a unique and evolving experience of inequality. Meaningful deliberation is about offering periodic opportunities for constitutional reform, allowing for continuous feedback, reflection, and learning.

Background Nursing should have a fundamental role in the development of health policies. The current state of the educational system regarding leadership-related skills and political competence in nursing students is a field to explore. Objectives To explore Spanish nursing students' perceptions about their political competence. Design Cross-sectional study that was carried out between December 2019 and June 2020. Settings and participants Students of the Degree in Nursing at the Universitat Jaume I (Spain). Methods An ad hoc scale composed of 33 items was designed. Sociodemographic variables of interest for the study were collected, such as participation in organizations. A descriptive analysis of the sample and the scale and a bivariate analysis were carried out. Results 91.8% (n = 90) of items were answered by women. The 2nd (40.8%, n = 40) and 4th (29.6%, n = 29) courses were the most represented. 29.6% (n = 29) belonged to some association or organization, with sports (31.1%, n = 9), NGOs (17.2%, n = 5), cultural (17.2%, n = 5) and student organizations (13.8%, n = 4) being the most represented. Within these associations, 48.3% (n = 14) of participants claimed to have an active role. Statistically significant differences were observed by course in the Political Knowledge category (p = 0.030). The variables "belonging to an organization" and "having an active role" in it seemed to have more influence on the scale than the rest of the sociodemographic variables. Conclusions Learning strategies must benefit from skills and prior experiences of students to strengthen new learning. It also seems to be important to emphasize that the theoretical basis is important, but that promoting civic participation among students can be very relevant for the acquisition of political competence.

Social media provides ethno-racial immigrant groups—especially those who cannot vote due to factors such as lack of citizenship and limited English proficiency—the ability to mobilize and connect around collective issues. Online spaces and discussion forums have encouraged many Asian Americans to participate in public policy debates and take action on social justice issues. This form of digital group activism serves as an adaptive political empowerment strategy for the fastest-growing and largest foreign-born population in America. Asian American Connective Action in the Age of Social Media illuminates how associating online can facilitate and amplify traditional forms of political action. James Lai provides diverse case studies on contentious topics ranging from affirmative action debates to textbook controversies to emphasize the complexities, limitations, and challenges of connective action that is relevant to all racial groups. Using a detailed multi-methods approach that includes national survey data and Twitter hashtag analysis, he shows how traditional immigrants, older participants, and younger generations create online consensus and mobilize offline to foment political change. In doing so, Lai provides a nuanced glimpse into the multiple ways connective action takes shape within the Asian American community. ; https://scholarcommons.scu.edu/faculty_books/1523/thumbnail.jpg

Over the last 50 years there has been a paradigmatic shift in the climate of ideas and governing orthodoxy from Keynesian-corporatism to neoliberalism. Such paradigms provide the philosophical goals that are pursued by policy and practice and determine what are considered to be the legitimate means of attaining those goals. We use evolving policy and practice relating to the protection and management of street trees as a vehicle for examining the relations between the competing paradigms of corporatism and neoliberalism, and the ways that they are expressed 'on the ground'. In doing so we highlight the tensions between the amenity value and the economic value of street trees and between techniques for their estimation. The legitimacy of measures of the former, such as Helliwell and CAVAT, that embody corporatist concepts are subject to continuing challenges based on their (lack of) scientific rigour or economic principle. The strengths of measures of the latter, such as i-Tree, are emphasised on the same grounds. Such is the success of these efforts that the equation of the value of a street tree with an estimation of the price that people will pay for the ecosystem services it delivers is not seen as controversial.

Unlike almost most other studies of neoliberal universities and academic capitalism this book ethnographically explores and interprets those transformations and their contradictions empirically in the everyday practices of students, faculty members, and administrators at two public universities: NTNU in Norway and UCLA in California.Differently situated in global political economies, both are ambitious, prosperous campuses. The book refl exively examines their disturbing disputes about quality, competition, and innovation. It argues that some academic, bureaucratic, and corporate university governance practices are both unsustainable and undermining what some university students and faculty already do well: circulate interdisciplinary knowledge and its making globally across the diasporic domains of academia, society, industry, and government while addressing the world's immediate challenges: power, inequities, and sustainability.It shows the important, strategic work of domesticating, co- morphing, and meshworking at the faultlines of emerging knowledge. This book is for students, faculty, society members, and policy makers who want to engage more effectively with contemporary universities that increasingly serve as busy crossroads for sharing ideas and how to make them. It will be of interest to workers and scholars in the interdisciplinary fi elds of higher education studies, critical university studies, and critical public infrastructure studies, plus science, technology, and society studies.
