Research on Augmented Reality in education has demonstrated that AR applications designed with diverse components boost student motivation in educational settings. However, most of the research conducted to date, does not define exactly what those components are and how these components positively affect student motivation. This study, therefore, attempts to identify some of the components that positively affect student motivation in mobile AR learning experiences to contribute to the design and development of motivational AR learning experiences for the Vocational Education (...) and Training level of education. To identify these components, a research model constructed from the literature was empirically validated with data obtained from two sources: 35 students from four VET institutes interacting with an AR application for learning for a period of 20 days, and a self-report measure obtained from the Instructional Materials Motivation Survey. We found that the following variables: use of scaffolding, real-time feedback, degree of success, time on-task and learning outcomes are positively correlated with the four dimensions of the ARCS model of motivation: Attention, Relevance, Confidence, and Satisfaction. Implications of these results are also described. (shrink)

Hasta la publicación del libro de Jorge M. Ayala sobre los años que García Bacca permaneció en la institución claretiana, sabíamos muy poco sobre esa fase de la vida del filósofo hispanovenezolano. Los datos que aporta Ayala sobre estos años resultan claves para conocer mejor su vida. Pero el enfoque desde el que Ayala ha escrito su libro limita de una forma importante los incontestables logros que contiene. El objeto de este artículo es desmontar muchas de las apreciaciones (...) y juicios que Ayala proyecta sobre García Bacca, así como sobre todo el sesgado horizonte interpretativo desde el que enfoca los sucesos de la guerra civil española y las muchas víctimas que causó, sobre todo entre los religiosos claretianos.

We give characterizations for the sentences "Every $\Sigma^1_2$-set is measurable" and "Every $\Delta^1_2$-set is measurable" for various notions of measurability derived from well-known forcing partial orderings.

Martin Buber believed that life's deepest truth lies in human relationships. In this classic work he puts this belief into practice, applying it to the concrete problems of contemporary society.

In lieu of an abstract, here is a brief excerpt of the content:.. MERELY A MAN OF LETTERS" an interview with Jorge Luis Borges* Philosophy and Literature: Why don't you tell us about some of the philosophers who have influenced your work and in whom you have been the most interested? Jorge Luis Borges: Well, I think that's an easy one. You might talk in terms of two: Berkeley and Schopenhauer. But I suppose Hume might be worked in (...) also, because, after all, Hume refutes Berkeley. Really, he comes from Berkeley—even if Berkeley comes from Locke. You might think of Locke, of Berkeley, and of Hume as being three links in an argument..... But I suppose that when someone refutes someone else in philosophy, he is carrying on the argument. P&L: And Schopenhauer? Borges: Schopenhauer is very different from Hume. Of course, Schopenhauer had his idea of the Will. That is not to be found in Hume.... The case of Berkeley was different. I suppose he thought of God as being aware of all things all the time, if I don't get him wrong. If we go away, does this room disappear? No, because God is thinking about it. Now, in the case of Schopenhauer, I was rereading Die Welt als Wille und Vorstellung, The World as Will and Idea, and I was rather taken aback, or baffled I should say, puzzled by something that keeps on recurring in Schopenhauer. Of course it may have been a slip of the pen, but as he goes back to it, and as he was a very careful writer, I wonder if it is a slip of the pen. For example, Schopenhauer begins by saying that the universe, the stars, the spaces in between, the planets, *On April 14, 1976, two editors of Philosophy and Literature, along with an interested colleague, interviewed Jorge Luis Borges at Michigan State University, where he held a position as visiting professor for the winter term. These remarks are edited from the transcript of that conversation. 337 338Philosophy and Literature this planet, those things, have no existence—except in the mind which perceives them. But then, to my surprise—and I suppose you can explain this to me, since you are philosophers and I am not—what Schopenhauer says is that all those things have no existence except in the brain. And that the universe—I remember these words, I don't think I'm inventing them now—"ist ein Gehirnphänomen," that the world is a cerebral phenomenon. Now, I was baffled. Because, of course, if you think of the universe, I suppose the brain is as much a part of the external world as the stars or the moon. The brain after all is a system of visual, of tactile, perceptions. He keeps on insisting on the brain. I don't think, for example, that Bishop Berkeley insists on the brain, or Hume, who would have insisted on the mind, consciousness. P&L: People sometimes say that they see Berkeley in stories like "Orbis Tertius." Borges: Yes, I suppose they do. Well, of course. But in that story I was led by literary means also. P&L: How do you distinguish the literary from the philosophical means in that story? Could you explain that? Borges: Very easily.... Encyclopedias have been my chief reading. I have always been interested in encyclopedias. I used to go to the Biblioteca National in Buenos Aires—and since I was so shy, I felt I could not cope with asking for a book, so I looked on the shelves for the Encyclopaedia Britannica. I would pick up any chance volume and I would read it. One night I was richly rewarded, because I read all about the Druses, Dryden and the Druids—a treasure trove, no?—all in the same volume, "Dr-." Then I came to the idea of how fine it would be to think of an encyclopedia... a very rigorous one of course, of an imaginary world, where everything should be linked. For example, you would have a language and then a literature, and then a history and so on. Then I thought I would write a story of a fancy encyclopedia. Of course that would require many different people to write it... (shrink)

Neste artigo indicaremos que a proposição fundamental dos cursos de Geografia física de Kant é: o homem é habitante da Terra. Para validar essa tese, alinharemos a metodologia utilizada por Kant nos cursos de Antropologia e de Geografia física, a fim de evidenciar as convergências e divergências desses cursos. Além disso, também compararemos a metodologia empregada por Kant na História natural e na Geografia física, porque a distinção entre essas ciências nos permitirá ratificar a tese aqui defendida e delimitar os (...) critérios de validade da proposição acima indicada. Em Physische Geographie, Kant diferencia as proposições dessas disciplinas da seguinte maneira: as proposições geográficas se referem aos homens como habitantes da Terra, mas os investiga sem nenhuma perspectiva histórica, ou seja, os investiga no tempo presente. Ao contrário disso, as proposições naturalistas investigam os seres humanos em uma linha temporal sucessiva, a fim de demonstrar o que natureza fez deles. Dito isso, o problema central da história natural é demonstrar que os diferentes povos possuem uma origem comum e o problema central da geografia física é demonstrar de que maneira o habitat influencia no processo civilizador, moralizador, político e religioso dos diferentes povos.

Let A[ω]ω be a maximal almost disjoint family and assume P is a forcing notion. Say A is P-indestructible if A is still maximal in any P-generic extension. We investigate P-indestructibility for several classical forcing notions P. In particular, we provide a combinatorial characterization of P-indestructibility and, assuming a fragment of MA, we construct maximal almost disjoint families which are P-indestructible yet Q-destructible for several pairs of forcing notions . We close with a detailed investigation of iterated Sacks indestructibility.

We investigate which filters onωcan contain towers, that is, a modulo finite descending sequence without any pseudointersection. We prove the following results:Many classical examples of nice tall filters contain no towers.It is consistent that tall analytic P-filters contain towers of arbitrary regular height.It is consistent that all towers generate nonmeager filters, in particular Borel filters do not contain towers.The statement “Every ultrafilter contains towers.” is independent of ZFC.Furthermore, we study many possible logical implications between the existence of towers in filters, (...) inequalities between cardinal invariants of filters $,${\rm{co}}{{\rm{f}}^{\rm{*}}}\left$,${\rm{no}}{{\rm{n}}^{\rm{*}}}\left$, and${\rm{co}}{{\rm{v}}^{\rm{*}}}\left$), and the existence of Luzin type families, that is, if${\cal F}$is a filter then${\cal X} \subseteq {[\omega ]^\omega }$is an${\cal F}$-Luzin family if$\left\{ {X \in {\cal X}:|X \setminus F| = \omega } \right\}$is countable for every$F \in {\cal F}$.

Let κ < λ be regular uncountable cardinals. Using a finite support iteration (in fact a matrix iteration) of ccc posets we obtain the consistency of b = a = κ < s = λ. If μ is a measurable cardinal and μ < κ < λ, then using similar techniques we obtain the consistency of b = κ < a = s = λ.

In the 10 years after the launch of the United Nations Global Compact (GC), there have been very few empirical assessments of the initiative in the academic literature. In this study, drawing from institutional theory and the resource-based view of the firm, we examine motivations of business participants to adopt the GC principles in the Spanish context. Using survey data from Spain – the country reporting the highest volume of business participants in the GC – we find that external institutional (...) forces as well as internal organisational resources shape motivations for adopting GC principles. In particular, we find that early and late adopters are motivated similarly by the perceived opportunity of achieving image gains, while late adopters are motivated more by economic gains than early adopters. We further find that regardless of the extent of internal intangible resources possessed, firms are similarly motivated by economic gains. The results also show that companies with more intangible resources are motivated more by image gains than those with fewer resources. Our findings indicate that contrary to its earlier days, economic gains have emerged as an important motivator for the adopters of the GC principles with image gains still being an important motivator.

We investigate some aspects of bounding, splitting, and almost disjointness. In particular, we investigate the relationship between the bounding number, the closed almost disjointness number, the splitting number, and the existence of certain kinds of splitting families.

We show that every dominating analytic set in the Baire space has a dominating closed subset. This improves a theorem of Spinas [15] saying that every dominating analytic set contains the branches of a uniform tree, i.e. a superperfect tree with the property that for every splitnode all the successor splitnodes have the same length. In [15], a subset of the Baire space is called u-regular if either it is not dominating or it contains the branches of a uniform tree, (...) and it was proved that Σ21-Kσ-regularity implies Σ21-u-regularity. Here we show that these properties are in fact equivalent. Since the proof of analytic u-regularity uses a game argument it was clear that determinacy implies u-regularity of all sets. Here we show that an inaccessible cardinal is enough to construct a model for projective u-regularity, namely it holds in Solovay's model. Finally we show that forcing with uniform trees is equivalent to Laver forcing. (shrink)

Implementing corporate social responsibility (CSR) in supply chains is not a trivial task. In fact, many firms in recent years have publicly proclaimed that in order to keep their CSR commitments, they had to reduce reliance on external suppliers by vertically integrating their operations. Our aim in this article is to examine whether there is truly a relationship between a firm’s CSR performance and its level of vertical integration. Drawing on a multi-industry sample of 2,715 firm-year observations, and after addressing (...) endogeneity concerns, we demonstrate that firms with higher CSR performance tend to vertically integrate more (or, outsource less). We also demonstrate that this tendency is weaker for firms that have higher degrees of asset specificity or international diversification. Our core conclusion is that CSR performance and outsourcing are at odds, but firms can reconcile this tension by deepening their collaborations with suppliers. (shrink)

We show the consistency of ${\frak o} <{\frak d}$ where ${\frak o}$ is the size of the smallest off-branch family, and ${\frak d}$ is as usual the dominating number. We also prove the consistency of ${\frak b} < {\frak a}$ with large continuum. Here, ${\frak b}$ is the unbounding number, and ${\frak a}$ is the almost disjointness number.

The article offers an insight into road traffic accidents by unravelling both the internal elements and the social context of the so-called car–driver hybrid. It takes a critical perspective on the art of designing road safety. More importantly, it seeks to contribute to social studies of transport and mobility through development of analytical concepts within the discipline. The points of departure are the inherent ambiguities of mobility. The author suggests that ‘being in traffic’ is always determined by coexisting forms of (...) mobility and immobility. This ambivalent stage is then called motility. The author discusses car-drivers as motile hybrids, as they are mobile and immobile, as well as subjects and objects at the same time. In order to apply these concepts, the question of what happens to hybrids in crashes is addressed, employing Bruno Latour’s concept of ‘immutable mobiles’. The article concludes with a discussion of the social role of road safety experts, arguing that transport safety experts create a specific kind of spatio-temporal order within which the motile hybrid exists. It is the safety professional who decides when to take agency away from the subject and give it to the object, and it s/he who determines where to slow down and where to speed up the car–driver hybrid.

It is relatively consistent with ZFC that every countable $FU_{fin} $ space of weight N₁ is metrizable. This provides a partial answer to a question of G. Gruenhage and P. Szeptycki [GS1].

En este artículo abordo dos obstáculos para la articulación política democrática en un régimen neoliberal: la exclusión y la división social del trabajo. Para ello, partiré de una primera delimitación de rasgos comunes a las movilizaciones sociales en el neoliberalismo desde el punto de vista de su relación con la política institucional. Después, reformularé esa misma caracterización a través del concepto relacional del Estado procedente de Nicos Poulantzas y reelaborado por Étienne Balibar, para centrarme en el análisis de los dos (...) problemas centrales del artículo: la exclusión y la reproducción de la división social del trabajo en la política. Para el tratamiento de estas cuestiones me serviré del marco de análisis desarrollado por Balibar a partir de los conceptos de igualibertad y Estado nacional-social. Por último, en las conclusiones, propondré respuestas democráticas para los dos problemas señalados. (shrink)

The aim of this paper is to present a revision of international versions of the Utrecht Work Engagement Scale and to describe the psychometric properties of a Portuguese version of the UWES-9 developed simultaneously for Brazil and Portugal, the validity evidence related with the internal structure, namely, Dimensionality, measurement invariance between Brazil and Portugal, and Reliability of the scores. This is the first UWES version developed simultaneously for both countries, and it is an important instrument for understanding employees' work engagement (...) in the organizations, allowing human resources departments to better use workforces, especially when they are migrants. A total of 524 Brazilian workers and 522 Portuguese workers participated in the study. Confirmatory Factor Analysis, group comparisons, and Reliability estimates were used. The use of workers who were primarily professionals or administrative support, according to ISCO-08, reinforced the need to collect data on other professional occupations. Confirmatory factor analysis showed acceptable fit for the UWES-9 original three-factor solution, and a second-order factor structure has been proposed that presented an acceptable fit. Full-scale invariance was obtained between the Portuguese and Brazilian samples, both for the original three-factor first-order and second-order models. Data revealed that Portuguese and Brazilian workers didn't show statistically significant differences in the work engagement dimensions. This version allows for direct comparisons of means and, consequently, for performance of comparative and cross-cultural studies between these two countries. (shrink)

The concept of shared mental models refers to the shared understanding among team members about how they should behave in different situations. This article aimed to develop a new shared mental model measure, specifically designed for the refereeing context. A cross-sectional study was conducted with three samples: national and regional football referees (n = 133), national football referees and assistant referees and national futsal referees (n = 277), and national futsal referees (n = 60). The proposed version of the Referee (...) Shared Mental Models Measure (RSMMM) has 13 items that are reflected on a single factor structure. The RSMMM presented good validity evidence both based on the internal structure and based on relations to other variables (presenting positive associations with team work engagement, team adaptive performance, and team effectiveness). Such promising psychometric properties point to an optimistic outlook regarding its use to measure shared mental models in futsal and football referee teams. -/- . (shrink)

Rescue workers have a stressful and risky occupation where being engaged is crucial to face physical and emotional risks in order to help other persons. This study aims to estimate work engagement levels of rescue workers (namely comparing nurses, firefighters, and police officers) and to assess the validity evidence related to the internal structure of the Portuguese versions of the UWES-17 and UWES-9, namely, dimensionality, measurement invariance between occupational groups, and reliability of the scores. To evaluate the dimensionality, we compared (...) the fit of the three-factor model with the fit of a second-order model. A Portuguese version of the instrument was applied to a convenience sample of 3,887 rescue workers (50% nurses, 39% firefighters, and 11% police officers). Work engagement levels were moderate to high, with firefighters being the highest and nurses being the lowest engaged. Psychometric properties were evaluated in the three-factor original structure revealing acceptable fit to the data in the UWES-17, although the UWES-9 had better psychometric properties. Given the observed statistically significant correlations between the three original factors, we proposed a 2nd hierarchal structure that we named work engagement. The UWES-9 first-order model obtained full uniqueness measurement invariance, and the second-order model obtained partial (metric) second-order invariance. (shrink)

Using a notion of rank for Hechler forcing we show: assuming ωV1 = ωL1, there is no real in V[d] which is eventually different from the reals in L[ d], where d is Hechler over V; adding one Hechler real makes the invariants on the left-hand side of Cichoń's diagram equal ω1 and those on the right-hand side equal 2ω and (...) produces a maximal almost disjoint family of subsets of ω of size ω1; there is no perfect set of random reals over V in V[ r][ d], where r is random over V and d Hechler over V[r], thus answering a question of the first and second authors.

During the last few years, burnout has gained more and more attention for its strong connection with job performance, absenteeism, and presenteeism. It is a psychological phenomenon that depends on occupation, also presenting differences between sexes. However, to properly compare the burnout levels of different groups, a psychometric instrument with adequate validity evidence should be selected (i.e., with measurement invariance). This paper aims to describe the psychometric properties of the Oldenburg Burnout Inventory (OLBI) version adapted for workers from Brazil and (...) Portugal, and to compare burnout across countries and sexes. OLBI's validity evidence based on the internal structure (dimensionality, reliability, and measurement invariance), and validity evidence based on relationships with other variables (work engagement) are described. Additionally, it aims presents a revision of different OLBI's versions—since this is the first version of the instrument developed simultaneously for both countries—it is an important instrument for understanding burnout between sexes in organizations. Data were used from 1,172 employees across two independent samples, one from Portugal and the other from Brazil, 65 percent being female. Regarding the OLBI internal structure, a reduced version (15 items) was obtained. The high correlation between disengagement and exhaustion, suggested the existence of a second-order latent factor, burnout, which presented measurement invariance for country and sex. Confirmatory factor analysis of the Portuguese OLBI version presented good goodness-of-fit indices and good internal consistency values. No statistically significant differences were found in burnout between sexes or countries. OLBI also showed psychometric properties that make it a promising and freely available instrument to measure and compare burnout levels of Portuguese and Brazilian employees. (shrink)

Resumo O objetivo deste artigo é evidenciar que a ideia de antropologia pragmática desenvolvida nas versões dos cursos de antropologia, que são Collegentwürfe, Menschenkunde e Anthropologie Dohna-Wundlackende, se ocupa de uma definição moral, porque ela está subordinada à doutrina da prudência. Essa é compreendida como a capacidade de os seres humanos influenciarem uns aos outros, segundo certos fins, os quais deverão ser úteis na vida em sociedade. Além disso, delimita-se que o sentido do adjetivo “pragmático”, presente nessas versões dos cursos (...) de antropologia, foi retirado da obra Initia Philosophiae practicae prima, de Baumgarten, pois, nas anotações de Kant acerca dessa obra, os motivos pragmáticos sempre determinarão leis privadas do arbítrio, as quais poderão, a priori, representar um interesse moral e, a posteriori, a realização de um fim almejado pelo ser racional finito. Por essa razão, defende-se haver nas obras kantianas citadas uma sinonímia entre a noção de antropologia pragmática e de doutrina da prudência.This article aims to evidence that the idea of pragmatic anthropology developed in the versions of the courses of anthropology that are Collegentwürfe, Menschenkunde and Anthropologie Dohna-Wundlackende, occupies of a moral definition, because it is subordinated to the doctrine of prudence. This doctrine is understood as the capacity from the human beings to influence each other according to certain goals, the ones that should be useful in social life. Besides that, we will delimit that the meaning of the pragmatic adjective present in these versions of the courses of anthropology was withdrawn from the work Initia Philosophiae practicae prima from Baumgarten, because in the notes of Kant about this work the pragmatic motives will always determine private laws of the will, the ones who may, a priori, represent a moral interest and, a posteriori, the accomplishment of a desired end by its finite rational being. By this reason, we defend to have in the quoted Kantian works a synonymy between the notion of pragmatic anthropology and the doctrine of prudence. (shrink)

This article focuses on an Ethno philosophy through intercultural philosophy and dialogue. This philosophical reflection stands on an historical, cultural and ethical subject known as “us” in the Latin American experience. From an intercultural dialog and its philosophy, there will be an approach of Ethno philosophy as a new way of thinking and doing philosophy from interculturalism, the recovery of ancestral knowledge and the dialogue of different forms of knowledge from the diversity of worldviews of different cultures and ethnic groups.
