This study aims to formulate a mechanism design in the derivatives market, summarizing a framework to set up the Brazilian electricity futures market.

This exploratory study formulates a mechanism design in the derivatives market, summarizing a framework to set up the Brazilian electricity futures market.

The results show a positive economic outcome for the creation of the Brazilian futures electricity market.

The main feature in this work is to summarize a framework to set up the Brazilian electricity futures market applying mechanism design, applicable in other countries. The features of the mechanism are the space of expected results (Z), the strategies to survey the environmental space (θ) and the mechanism design – messages space (M).

To encourage sustainable consumer practices, public policy makers introduce new ecological measures, including mandatory programmes that require companies to provide environmental information about their products, even if the information is not flattering. Few academic studies consider the potential impacts of such mandatory eco-labels on consumer behaviour; the purpose of this paper is to seek to identify conditions in which a generalized eco-label in stores might modify consumers’ purchase choices.

Two quasi-experimental studies (n=333, 126) manipulate environmental information with a simple, traffic light – shaped eco-label. The measures focus on respondents’ choice or purchasing intentions, perceptions of the environmental harmfulness of each product, and individual characteristics (i.e. environmental concern, price sensitivity, familiarity with environmental information about the product category).

The presence of an eco-label influences consumers’ beliefs about products’ environmental harm and thus choice. The effect of perceived harmfulness on choice is moderated by environmental concern and price sensitivity, though combined effects arise for only one of the two product categories tested (dish soap, not yoghurt). With a third product category (paper towels), Study 2 confirms the influence of familiarity with environmental information.

Familiarity with environmental information accounts for some differences across product categories, but other factors also come into play. These results must be interpreted carefully due to the use of a fictive eco-label.

This paper examines the potential effects of a generalized, mandatory programme. It also addresses the lack of consistent label effectiveness across product categories, with a possible explanation based on perceived familiarity with environmental information.

This study aims at translating and adapting a common and widely used proxy rated cognitive screening tool – Informant Questionnaire on Cognitive Decline in the Elderly (IQCODE) into Hausa language and also to evaluate the instrument’s psychometric properties.

IQCODE was translated and adapted using a qualitative process involving experts and the adapted version was then evaluated against a gold standard (Diagnostic and Statistical Manual of Mental Disorder V criteria for neurocognitive disorders) with older adults subjects (N = 100), while its reliability (internal consistency) was also evaluated. Descriptive statistics of mean and frequencies, and inferential statistic of receiver operating curve analysis and Cronbach’s alpha coefficient were used for data analysis at an alpha level set at 0.05.

The Hausa IQCODE has a sensitivity value of 73.3%, specificity value of 71.8% and optimal cut-off values of between 3.2 and 3.3. For his adapted instrument the area under the Curve (AUC) curve is 0.79 (95% CI: 0.663–0.919; std. err: 0.066; P = 0.000), and Cronbach’s alpha value of 0.819 was obtained indicating that the adapted instrument has good internal consistency.

The adapted IQCODE is a valid and reliable proxy based cognitive screening tool for the older adult Hausa speakers in Maiduguri. However, clinician and researcher might want to consider different optimal cut-off points when using this tool to screen or to monitor cognitive changes among older adults.

This research paper translated and adapted Hausa IQCODE into Hausa language. And it gives information on the validity and reliability of the adapted tool alongside with new optimal cut-off for cognitive screening by proxy among older adult patients in Nigeria.

The purpose of this two-wave longitudinal study was to examine the role of mindfulness as mediator between social support and engagement and as a moderator in the relationship between work overload and burnout, both cross-sectionally and after one year.

The sample consisted of 243 Peruvian teachers. Structural equation modeling and SPSS Process Macro were used to test the hypothesis.

The results show that mindfulness mediated the relationship between social support and engagement at both times but doesn't moderate the relationship between work overload and burnout at either time.

This study highlights the role of mindfulness as a valuable personal resource in the workplace, as it facilitates a higher functioning at work while identifying relevant organizational characteristics that have an influence in its use.

El propósito de este estudio longitudinal de dos olas fue examinar el papel de mindfulness como mediador entre el apoyo social y el engagement en el trabajo; así como moderador en la relación entre la sobrecarga de trabajo y el burnout, tanto transversalmente como después de un año.

La muestra estuvo conformada por 243 profesores peruanos. Se utilizó el modelo de ecuaciones estructurales (SEM en inglés) y Process Macro para SPSS para probar la hipótesis.

Los resultados muestran que mindfulness media la relación entre el apoyo social y engagement en ambos momentos, pero no modera la relación entre la sobrecarga de trabajo y el burnout en ninguno de los dos.

Este estudio destaca el papel del mindfulness como un recurso personal valioso en el trabajo, ya que facilita un mejor funcionamiento al tiempo que identifica características organizacionales relevantes que influyen en su uso.
