The aim of our study was to test the effectiveness of the “three good things for others” intervention. We used the randomized controlled trial method, with four measurements (pretest, posttest, follow-up after 2 weeks, follow-up after 4 weeks) and with random assignment of participants to experimental and placebo control groups. We investigated the effects of the intervention on prosocial behavior, and in addition on positive and negative affect, and positive orientation (a general tendency to approach reality in a positive way). (...) The results showed an increase in positive affect and a decrease in negative affect in the experimental group a day after the intervention. These effects, however, did not endure over the next 2 or 4 weeks. We also observed a statistically significant increase in prosocial behavior in the placebo control group, in which participants were engaged in a task of recalling childhood memories. The results are discussed and recommendations for future studies are proposed. (shrink)

Local food has become the rising star of the sustainable agriculture movement, in part because of the energy efficiencies thought to be gained when food travels shorter distances. In this essay I critique four key assumptions that underlie this connection between local foods and energy. I then describe two competing conclusions implied by the critique. On the one hand, local food systems may need a more extensive and integrated transportation infrastructure to achieve sustainability. On the other hand, the production, transportation, (...) and consumption of local foods are fundamentally as reliant on fossil fuels as are long distance foods. A more holistic approach to energy use in the food system is needed to determine which particular sociotechnical factors optimize energetic sustainability. (shrink)

The trajectory of the public discourse on agriculture in the twentieth century presents an interesting pattern:shortly after World War II, the manner in which farming and farmers were discussed underwent a profound shift. This rhetorical change is revealed by comparing the current debate on farmland preservation with a tradition of agricultural discourse that came before, known as “agrarianism.” While agrarian writers conceived of farming as a rewarding life, a public good, and a source of moral virtue, current writers on farmland (...) preservation speak of farming almost entirely in utilitarian terms describing its productive capacity and its economic returns. Proponents of farmland preservation use essentially the same underlying framework as critics of preservation:n “economic utilitarian” paradigm that purports to eschew normative values and evaluate land use decisions based on economic criteria only. I argue that, despite their good intentions, farmland preservationists are doomed to piecemeal victories at best, because their arguments, which rely on a utilitarian justification and disregard the agrarian ethic, are inadequate. Without expanding its focus beyond farmland to encompass farming and farmers, the movement risks losing both integrity and effectiveness. (shrink)

As volunteer engagement in non-governmental organizations vary between individuals, it is vital to get to know its predictors. It can be of profit to volunteers and the ones who profit from their activities. The aim of present study was to examine a model explaining volunteer engagement examining volunteer self-efficacy as a mediator and personality traits, job resources as its predictors. Respondents were asked to fill in questionnaires accessible online. Those consisted of demographic questions as well as Ten-item Personality Inventory, and (...) three measures adjusted to volunteer environment: Work Design Questionnaire, General Self-Efficacy Scale, and Work Engagement Scale. Results. Results of hierarchical regression analyses showed that conscientiousness, skill variety and self-efficacy are statistically significant predictors of volunteer engagement. It was shown that the effects of conscientiousness and skill variety on volunteer engagement are mediated by volunteer self-efficacy. (shrink)

W pracy przedstawiono wyniki badań dotyczących przydatności zawodowej inży­nierów ochrony wód. Stwierdzono, że więk­szość absolwentów pracuje zgodnie z ukończonym kierunkiem studiów. Absolwenci wysoko ocenili swoje przygotowanie z technologii, niżej z techniki i ekonomiki. Znacznie lepsze było ich przygotowanie do zawodu teoretyczne niż praktyczne.

Present, as Manuel Castells (1996) notes, we live in the information age. Knowledge and the way it is acquired and processed are the driving forces of the economy, and information processing systems are the strength of economies. The aim of this article is to identify the key role of the information supply phenomenon in contemporary socio-economic processes. The initial part of the article will define such concepts as: information, infodemia, information market, in the further part examples of the use of (...) information in the process of forming social behaviour in the market context will be presented. For this purpose, three major economic crises from the turn of the 20th and 21st century will be used cross-sectionally. The first will be described as the dot-com crisis, i.e. the first global Internet players, which led to the collapse or loss of value of many global Internet platforms through the creation and bursting of a speculative bubble. The second crisis described below was related to the collapse of Lehman Brothers, a leading US bank, and the US housing crisis. In the above case, both supply and concealment of information in the public sphere could be observed. The last crisis described is the crisis related to the SARS-COV2 pandemic, in which dis- and mis- information activities proved to be crucial. (shrink)

ABSTRACT The history of Latin America, the history of disease, medicine, and public health, and global history are deeply intertwined, but the intersection of these three fields has not yet attracted sustained attention from historians. Recent developments in the historiography of disease, medicine, and public health in Latin America suggest, however, that a distinctive, global approach to the topic is beginning to emerge. This essay identifies the distinguishing characteristic of this approach as an attentiveness to transfers of contagions, cures, and (...) medical knowledge from Latin America to the rest of the world and then summarizes a few episodes that demonstrate its promise. While national as well as colonial and neocolonial histories of Latin America have made important contributions to our understanding, works taking the global approach have the potential to contribute more directly to the decentering of the global history of disease, medicine, and public health.

A sense of success, perception of economic crisis and the form of occupational activity The studies presented attempt to outline a relationship between a feeling of success, the perception of economic crisis and the form of occupational activity. The article shows the results of empirical research conducted among 341 economically active people and concerns the psychological differences between them in Poland. The theoretical basis of the research is the new model of success by Dej, Stephan, Gorgievsky. This research has proven (...) the existence of significant statistical differences in a sense of success between entrepreneurs, employees in private companies, and employees in state-owned companies, but there are no differences in perception of economic crisis. People who scored a high general result in a feeling of success perceive economic crisis as harmless. The results show that being an entrepreneur is the most beneficial activity from a mental health standpoint. (shrink)

Type 2 diabetes has been considered a public health threat due to its growing prevalence, particularly in the older population. It is important to know the effects of psychosocial stress and its potential consequences for some basic cognitive processes that are important in daily life. Currently, there is very little information about how people with T2D face acute psychosocial stressors, and even less about how their response affects working memory, which is essential for their functionality and independence. Our aim was (...) to characterize the response to an acute laboratory psychosocial stressor and its effects on WM in older people with T2D. Fifty participants with T2D from 52 to 77 years old were randomly assigned to a stress or control condition. Mood and physiological responses to tasks were measured. In addition, participants completed a WM test before and after the stress or control task. Our results showed that the TSST elicited higher negative affect and greater C and sAA responses than the control task. No significant differences in WM were observed depending on the exposure to stress or the control task. Finally, participants who showed higher C and sAA responses to the stressor had lower WM performance. Our results indicate that medically treated older adults with T2D show clear, typical mood and physiological responses to an acute psychosocial stressor. Finally, the lack of acute psychosocial stress effects on WM suggests that it could be related to aging and not to this disease, at least when T2D is adequately treated. (shrink)

¿De qué hablamos cuando decimos Diseño Sustentable? El diseño sustentable podría definirse como el diseño que tiene en cuenta los aspectos ambientales en todos los niveles de producción. Así mismo, persigue el objetivo de fabricar productos que aporten el menor impacto posible en el ecosistema a lo largo de todo el ciclo de vida. Es muy difícil encontrar productos de consumo que cumplan puntualmente con los Preceptos del eco diseño y que sean exitosos en el mercado. Ante esta situación es (...) necesario revisar los aspectos involucrados en la concepción de un nuevo producto: ¿El rol del diseñador es el adecuado?, ¿Existe una seria y responsable conciencia por parte de los empresarios para llevar adelante un proyecto de eco diseño?, ¿Son los productos eco lo suficientemente atractivos para captar la atención de los consumidores?

La Biodiversidad biológica implica una gran responsabilidad para el ser humano, y somos quienes debemos cuidar para que no se pierda, pero a veces no está en nuestras manos protegerla, esto debido a que se presenta la pandemia del Covid-19 y el plantel tuvo que ser abandonado. Las plantas existentes en dicho plantel se secaron o están por perderse, así mismo como los animales silvestres de la región; actualmente estamos en semáforo verde y ya se pueden cuidar las plantas regándolas (...) constantemente. Para el cuidado de la biodiversidad es necesario que toda la comunidad tanto del Municipio como los que estamos involucrados en el plantel CECYTEM Valle de Chalco Solidaridad unamos esfuerzos para preservar tanto a plantas como a animales, y que si se llegará a presentar un rebrote de la pandemia formar comisiones para el cuidado de dicha biodiversidad.
