Semantically Consistent Regularization for Zero-Shot Recognition

The role of semantics in zero-shot learning is considered. The effectiveness of previous approaches is analyzed according to the form of supervision provided. While some learn semantics independently, others only supervise the semantic subspace explained by training classes. Thus, the former is able to constrain the whole space but lacks the ability to model semantic correlations. The latter addresses this issue but leaves part of the semantic space unsupervised. This complementarity is exploited in a new convolutional neural network (CNN) framework, which proposes the use of semantics as constraints for recognition.Although a CNN trained for classification has no transfer ability, this can be encouraged by learning an hidden semantic layer together with a semantic code for classification. Two forms of semantic constraints are then introduced. The first is a loss-based regularizer that introduces a generalization constraint on each semantic predictor. The second is a codeword regularizer that favors semantic-to-class mappings consistent with prior semantic knowledge while allowing these to be learned from data. Significant improvements over the state-of-the-art are achieved on several datasets.Comment: Accepted to CVPR 201

Reidemeister torsion and Integrable Hamiltonian systems

In this paper we compute the Reidemeister torsion of a isoenergetic surface for the integrable Hamiltonian system on the four-dimensional symplectic manifold. We use the spectral sequence defined by the filtration and following Witten-Floer ideas we bring into play the orbits connecting the critical submanifolds.Comment: 18 pages, amstex, 47 KB, no figure

Quality of Working Life and Employee Outcomes: A Literature Review

Quality of working life (QWL) is a research field studied since the 1970s, which has grown considerably since then (Grote & Guest, 2017). QWL covers an employee’s feelings about various dimensions of his or her work (Mosadeghrad, Ferlie & Rosenberg, 2011) and includes dimensions related with home-work interface, working condition, job and career satisfaction, control at work, stress at work, employee commitment and general well-being (Fontinha, Van Laar & Easton, 2016). At an individual level, positive outcomes of QWL include reduced absenteeism, lower turnover, improved job satisfaction, improved individual productivity (Mosadeghrad, Ferlie & Rosenberg, 2011), but studies that analyze, in a systematic way, all the employee outcomes associated to QWL are scarce. Following the systematic literature review (SLR) methodology, this article aims to identify the employee outcomes associated to the QWL construct. This article specifically explores research studies that have examined the QWL and consequences of it to individuals in a given organizational setting. Since our focus was to gain insight on the empirical investigation about QWL, we exclude studies with a primary focus on model development or testing measurement instruments. Extensive research has been performed at PROQUEST and EBSCO databases. The terms included the following on the title of the document: quality of life at work, work-related quality of life, quality of working life, working-life quality. Only the work-related consequences of QWL have been considered. The search has been limited to peer reviewed articles, theses, and conference papers published in the English language, between 1970 and 2017. The results show how a higher level of quality of life at work can improve several and relevant employee outcomes at work.CIEQV- Centro de Investigação em Qualidade de Vidainfo:eu-repo/semantics/publishedVersio

Psychological wellbeing, satisfaction with life and optimism in sports managers

In the discourse of its managers, the competitiveness of national sport is increasingly relative, or captive, to the constraints of competitiveness of the respective national economy with an obvious impact on productivity of sports associations and clubs, reflecting a market of very unequal competition. Now, if in the modern conception of happiness, the material aspect plays a major character, the positive subjective experience, usually linked to performance and sports productivity, should result therefore from immaterial and intangible capital consisting in human potential and virtues that interests to study

University surroundings andinfrastructures that are accessible and inclusive for all: listening to students with disabilities

The main topic of this article is architectural barriers and infrastructures as identified by university students with disabilities. The data presented is part of a much wider research project, sponsored by Spain’s Ministry of Economy and Competition. A biographical-narrative methodology was used for this study. The results presented have been classified based on one of five barrier types: urban (barriers that are outside the actual university campus), transport (public transportation and personal vehicles), building (obstacles inside university buildings), environmental (those elements within the classroom, including furniture, excessive noise or inadequate temperatures) and communication (these are divided into signposting and barriers when accessing information). Lastly, a variety of questions are considered in the conclusions which indicate that universities still need a certain degree of adaptation and readjustment to really be accessible and inclusive, in keeping with the principles of universal desig

Continuous Choreographies as Limiting Solutions of NN-body Type Problems with Weak Interaction

We consider the limit $N\to +\infty$ of $N$-body type problems with weak interaction, equal masses and $-\sigma$-homogeneous potential, $0<\sigma<1$. We obtain the integro-differential equation that the motions must satisfy, with limit choreographic solutions corresponding to travelling waves of this equation. Such equation is the Euler-Lagrange equation of a corresponding limiting action functional. Our main result is that the circle is the absolute minimizer of the action functional among zero mean (travelling wave) loops of class $H^1$
