The purpose of this paper is to present a synthesis of the origins and theoretical frameworks of adult mentoring practices in educational and workplace settings along with an analysis and critique of their application to mentoring processes.

The authors systematically analyzed books and articles published in peer-reviewed journals from 1978 to 2012 using qualitative meta-summary and qualitative meta-synthesis methodological approaches.

This systematic review of the literature resulted first, in an organized, historical framework of theories of adult mentoring in academic and workplace and educational contexts from 1978 to 2012. Second, it provided information regarding the recognized challenges in traditional mentoring endeavors that led to the more expansive concept of developmental networks and participation in communities of practice. Third, it served as a foundation for a critique of the theories as applied to mentoring relationships and programs.

The paper provides the theoretical foundation for future empirical work in the field of adult mentoring in educational and workplace settings.

This paper is the first to condense the vast theoretical frameworks that inform the field of adult mentoring in the twenty-first century.

Dementia is characterized by the progressive decline in cognitive and daily functioning. Although the decline is often the defining characteristic of dementia in biomedical models, several scholars highlight the preserved skills of persons with dementia. Identity, or a sense of self, is among the areas relatively preserved in the later stages of dementia. It is the window through which caregivers understand the subjective experiences of persons with dementia.

This qualitative exploratory study highlights the value of social relationships, particularly the role of the Filipino family in recognizing personhood and maintaining identity in dementia care. Preserving identity entails understanding the person’s unique characteristics that reflect one’s sense of self. In a highly collectivistic culture, such as the Philippines, the family is crucial to preserving identity and overall well-being in dementia. This study explores the perspectives of 15 Filipino caregivers as regards caring for a family member with dementia. Participants discuss changes in family structure and the challenges in dementia care. More importantly, they delve into strategies used to preserve identity and encourage life participation in their loved one with dementia. Essential Filipino cultural values in dementia care, such as collectivism, religion, and the values of filial piety and utang na loob (or debt of gratitude) are further discussed.

Binder jetting is a promising route to produce complex copper components for electronic/thermal applications. This paper aims to lay a framework for determining the effects of sintering parameters on the final microstructure of copper parts fabricated through binder jetting.

The knowledge gained from well-established powder metallurgy processes was leveraged to study the densification behaviour of a fine high-purity copper powder (D₅₀ of 3.4 µm) processed via binder jetting, by performing dilatometry and microstructural characterization. The effects of sintering parameters on densification of samples obtained with a commercial water-based binder were also explored.

Sintering started at lower temperature in cold-pressed (∼680 °C) than in binder jetted parts (∼900 °C), because the strain energy introduced by powder compression reduces the sintering activation energy. Vacuum sintering promoted pore closure, resulting in greater and more uniform densification than sintering in argon, as argon pressure stabilizes the residual porosity. About 6.9% residual porosity was obtained with air sintering in the presence of graphite, promoting solid-state diffusion by copper oxide reduction.

This paper reports the first systematic characterization of the thermal events occurring during solid-state sintering of high-purity copper under different atmospheres. The results can be used to optimize the sintering parameters for the manufacturing of complex copper components through binder jetting.

This study develops a model that explains export sales volume by destination based on a company's export marketing strategy. A seemingly unrelated regression model (SURE) simultaneously estimates the explanatory value of the different elements of the marketing strategy, as well as company characteristics, such as experience, size and motivation to export, on entry decisions to six different regional markets made by exporting companies in a southern European country. The data were collected from a sample size of 2,264 exporting companies. Findings confirm the importance of exporting experience and proactiveness in determining high export sales volumes in every regional market except for those psychologically close. Nevertheless, different marketing strategies depending on the region lead to high export sales volumes. For example, low price strategies in the case of Latin America or differentiation strategies based on the augmented product in the case of the USA generate high export sales. Promotional expenditures are of higher importance for distant markets, but for closer markets channel development is the key.

This paper aims to explore how nurses stay engaged in their work with the impact of structural empowerment and civility. It delves deeper into how kind, empathetic and respectful behaviours (civility) among colleagues influence the link between structural empowerment and nurses’ engagement.

Data was collected from 580 nurses working in a Public Hospital in the metropolitan area of Lisbon. Self-report questionnaires measuring civility, structural empowerment and engagement were administered. Hayes’ PROCESS macro for mediation analysis in SPSS was used to test the hypothesised model.

Results demonstrated that civility and structural empowerment were positively associated (r = 0.491, p < 0.01) also showing a positive influence on nurses’ engagement (r = 0.492, p < 0.01; r = 0.485, p < 0.01, respectively). Civility was found to partially mediate the association between structural empowerment and engagement (ß = 0.315, 95% CI [0.222, 0.417], 5,000 bootstrap resamples).

Findings from this study may be used for health-care employees and organisations, implying that when nurses perceive themselves as structurally empowered at work within a respectful environment, they experience an enhanced sense of community and involvement in their organization.

To the best of the authors’ knowledge, this is the first attempt in exploring the relationship of combined workplace civility, structural empowerment and engagement in a sample of Portuguese nurses. Future research could substantially increase our understanding of how civility contributes to a positive workplace.

Este artículo explora cómo las enfermeras se mantienen comprometidas (work engagement) en su trabajo con el impacto del empoderamiento estructural y la civilidad. Profundiza en cómo los comportamientos amables, empáticos y respetuosos (civilidad) entre colegas influyen en el vínculo entre el empoderamiento estructural y el work engagement de las enfermeras/os.

Se recogieron datos de 580 enfermeras que trabajaban en un hospital público del área metropolitana de Lisboa. Se administraron cuestionarios de autoinforme que medían la civilidad, el empoderamiento estructural y el work engagement. Se utilizó la macro PROCESS de Hayes para el análisis de mediación en SPSS con el fin de probar el modelo hipotetizado.

Los resultados demostraron que la civilidad y el empoderamiento estructural estaban positivamente asociados (r = 0.491, p < 0.01) mostrando también una influencia positiva en el work engagement de las enfermeras (r = 0.492, p < 0.01; r = 0.485, p < 0.01, respectivamente). Se observó que la civilidad mediaba parcialmente la asociación entre el empoderamiento estructural y el work engagement (β = 0.315, 95% CI [0.222, 0.417], 5,000 resamples bootstrap).

Los resultados de este estudio pueden ser utilizados por los empleados y las organizaciones sanitarias, ya que implican que cuando las enfermeras se perciben a sí mismas como estructuralmente empoderadas en el trabajo dentro de un entorno respetuoso, experimentan un mayor sentido de comunidad e implicación en su organización.

Hasta donde sabemos, este es el primer intento de explorar la relación entre la civilidad en el lugar de trabajo, el empoderamiento estructural y el work engagement en una muestra de enfermeras portuguesas. Futuras investigaciones podrían aumentar sustancialmente nuestra comprensión de cómo el civismo contribuye a un lugar de trabajo positivo.

Plant development and use as green corrosion inhibitors are already recognized as one of the most environmentally friendly and effective protocols. In recent years, efforts have been made to find green corrosion inhibitors as an alternative to synthetic inhibitors for metals in acid medium. This paper aims to report the investigation of use of aqueous extracts of Tamarindus Indica as green inhibitors for corrosion of metals within different circumstances.

The use of Tamarindus Indica extracts (leaves, stem, fruit pulp and fruit husk) as corrosion inhibitors for mild steel and aluminum in different mediums (HCl, H2SO4, formic acid and citric acid) at different temperatures was investigated.

The inhibitory efficiency of Tamarindus Indica extracts increases with increasing concentration and decreases with increasing temperature. Langmuir is the adsorption isotherm, and the extract (inhibitor) is a mixed-type inhibitor (physisorption and chemisorption).

Tamarindus extracts (leaves, stem, fruit pulp and fruit husk) are effective inhibitors and can be used to protect metals from corrosion at different circumstances.

To the best of the authors’ knowledge, this is the first review that discusses the use of Tamarindus Indica extracts as corrosion inhibitors for metals.
