Can servant leadership prevent hotel employee depression during the COVID-19 pandemic? A mediating and multigroup analysis.

The hospitality industry has been severely hit by the COVID-19 pandemic, with changes that have harmed employees' psychological well-being. However, having supervisors who are servant may make a difference. With a focus on serving others and the care taken to ensure their employees' highest priority needs are served, these leaders could help employees feel less depressed in these complicated times. By instilling servant behaviors in followers that help them become people that others can trust or with whom they can develop friendships, leaders could help these employees earn greater levels of personal social capital (PSC) through which to more successfully address pandemic times, especially if furloughed. Using structural equation modeling to analyze a sample of 205 hotel employees in Spain, we found that servant leadership directly decreases depression, and that PSC mediates this relationship. Our multigroup analyses (MGA) findings also reveal that when these employees are furloughed, the negative effect of PSC and the mediating role of PSC in this relationship is stronger. New light is thus shed on how servant leadership is effective in reducing employee depressive symptoms in times of severe changes such as those produced by the COVID-19 pandemic.

Contribution of Entrepreneurship to the Social Integration of People Intellectual Disabilities: A Case Study Based on the Analysis of Social Networks.

In an environment characterized by high unemployment rates among people with disabilities, the objective of the present work is to analyze entrepreneurship as a labor option which fully inserts people with intellectual disabilities (PwID) into their societies. In order to carry out this research, a case study methodology based on social network analysis has been adopted, given the nature of the variables analyzed. The results indicate that the fact of having managed to start up the company has been an important source of self-confidence and inspiration, as well as increasing and intensifying the social networks of PwID involved in the entrepreneurial project.

Simbiosis entre indicadores bibliométricos y alternativos para un índice métrico integrado / Symbiosis of bibliometric and alternative indicators for an integrated metric index

RESUMEN Resulta un gran desafío encontrar una vía que le otorgue un valor real a las publicaciones científicas desde su impacto y calidad. Esta realidad exige el uso de indicadores bibliométricos y más reciente, algunos alternativos para la evaluación, tanto de los autores como de sus publicaciones. En este sentido se realiza un estudio de ambos sistemas de indicadores y sus metodologías, desde el análisis de debilidades y potencialidades para su integración en un único índice, de modo que permita una evaluación más integral y justa de su impacto en la comunidad científica. Se indagó además sobre la importancia, necesidad y nivel de información que se posee sobre este tema en profesores cubanos de varias universidades, durante el período 2018-2019. El objetivo del presente trabajo es argumentar algunas ideas para el acercamiento gradual del Sistema de Evaluación y Acreditación de la Educación Superior de la República de Cuba (SEAES) a estos indicadores, teniendo en cuenta el nivel de atención que reciben por bases de datos reconocidas globalmente. Los resultados son parte del proyecto de investigación El impacto social de la formación continua como parte de los procesos de mejora de la calidad en la Universidad de Camagüey.

ABSTRACT It is a great challenge to find a way that gives real value to scientific publications based on their impact and quality. This reality has required the use of bibliometric indicators and more recent some alternative ones for the evaluation of both the authors and their publications. In this sense, an analysis of both systems of indicators and their methodologies is carried out, from the analysis of weaknesses and potentialities for their integration in an only index, so that it allows a more comprehensive evaluation. and just about its impact on the scientific community. It also inquired about the importance, need and level of information that is possessed on this subject in Cuban university professors from various universities, during the period 2018-2019. The objective of the present work is to argue some ideas are proposed for the gradual approach of SEAES to these indicators, taking into account the level of attention they receive through globally recognized databases. The exposed results are part of the research project The social impact of continuous training as part of the quality improvement processes at the University of Camagüey.

Occupational Health and Safety, Organisational Commitment, and Turnover Intention in the Spanish IT Consultancy Sector.

BACKGROUND: The purpose of this study is to analyse the impact that occupational health and safety policies have on employees' work and organisational commitment and, in turn, on their intention to leave the company. METHODS: For this study, we designed a questionnaire with a five-level Likert scale and distributed it among professionals from different companies in the IT consultancy sector in Spain. The data collected from 458 completed questionnaires were analysed using the partial least squares structural equation modelling (PLS-SEM) technique using the SmartPLS software. RESULTS: From the analysis of the data, it was concluded that there is indeed a positive relationship between occupational health and safety policies and employees' work and organisational commitment, as well as a negative relationship between these policies and the intention to leave the company. Similarly, there is a negative relationship between employees' work and organisational commitment and their turnover intention. CONCLUSIONS: Although, due to the activity of professionals in the sector, occupational health and safety has not been an area of priority, it was concluded from this study that an improvement in these areas would have a beneficial effect on the commitment of workers to the company, thus helping to reduce the high levels of turnover in the sector. Future lines of research, as well as their practical application and the limitations of the study, are indicated at the end of the paper.

How Upper/Middle Managers' Ethical Leadership Activates Employee Ethical Behavior? The Role of Organizational Justice Perceptions Among Employees.

Several studies have been conducted on ethical leadership and workplace ethical behavior but little is known about the role of organizational justice and each of its dimensions (procedural, distributive, interpersonal, informational) in this relationship. This study predicts that ethical leadership enhances organizational justice perceptions, including each of its specific dimensions, which in turn enhances employee ethical behavior. The results from two-wave survey data obtained from 270 employees in the Malaysian manufacturing industry confirm that ethical leadership has a positive impact on employee ethical behavior, and that organizational justice and each of its justice dimensions mediate this relationship, both individually and together. Importantly, interpersonal and informational dimensions show the strongest mediation effects. This paper highlights the actions and strategies that can help managers to effectively elevate the moral tone in their organizations. In particular, our findings show where managers must put more emphasis to foster an ethical workplace: on providing fair treatment (interpersonal justice) and honest information (informational justice).

Behavior of Internal Customer in Family Business: Strategies and Actions for Improving Their Satisfaction.

Determining the relevant aspects of family businesses (FBs) that make them increasingly competitive is the main objective of researchers in this field. Despite this, there is little empirical literature on the behavior of the internal customer (IC) in FBs or how businesses increase their satisfaction. Basing our work on psychological theories and with both quantitative and qualitative information from 31 semi-structured interviews, this work establishes certain characteristics of the ICs of the FB and proposes a series of guidelines for increasing their satisfaction, thereby facilitating the continuity of this type of business. FBs that are able to understand that the motivation of their ICs is more important than other qualities, and that this requires a more comprehensive management will be able to get sustainable competitive advantages in the future.

An organic/inorganic hybrid membrane as a solid "turn-on" fluorescent chemosensor for coenzyme A (CoA), cysteine (Cys), and glutathione (GSH) in aqueous media.

The preparation of a fluorogenic sensory material for the detection of biomolecules is described. Strategic functionalisation and copolymerisation of a water insoluble organic sensory molecule with hydrophilic comonomers yielded a crosslinked, water-swellable, easy-to-manipulate solid system for water "dip-in" fluorogenic coenzyme A, cysteine, and glutathione detection by means of host-guest interactions. The sensory material was a membrane with gel-like behaviour, which exhibits a change in fluorescence behaviour upon swelling with a water solution of the target molecules. The membrane follows a "turn-on" pattern, which permits the titration of the abovementioned biomolecules. In this way, the water insoluble sensing motif can be exploited in aqueous media. The sensory motif within the membrane is a chemically anchored piperazinedione-derivative with a weakly bound Hg(II). The response is caused by the displacement of the cation from the membrane due to a stronger complexation with the biomolecules, thus releasing the fluorescent sensory moieties within the membrane.

Putting to work organic sensing molecules in aqueous media: fluorene derivative-containing polymers as sensory materials for the colorimetric sensing of cyanide in water.

This paper describes a strategy followed to achieve a sensing phenomenon in aqueous media using water-insoluble organic molecules. A sensory polymeric material for the colorimetric sensing of cyanide in water has been developed based on the reactivity of this anion with a fluorene derivative.

Familial Alzheimer disease among Caribbean Hispanics: a reexamination of its association with APOE.

OBJECTIVES: To reexamine the association between the apolipoprotein E epsilon4 allele (APOE epsilon4) and familial Alzheimer disease (AD), and to search for novel genes that may be associated with susceptibility in Caribbean Hispanic families with a history of AD. METHODS: Families were identified in Caribbean Hispanic communities in the greater New York City area, the Dominican Republic, and Puerto Rico. Each family in the study cohort included at least 2 living relatives with a history of dementia. All family members underwent neuropsychological testing and medical and neurological examinations to establish the presence or absence of dementia and to specify the type of dementia. RESULTS: Over a 2(1/2)-year period, 203 families were identified. Of these, 19 families had at least 1 family member with onset of dementia before age 55 years, with 8 of the 19 families showing an association with a previously unreported presenilin mutation. Multiple cases of AD were identified in 29 families. Overall, there were 236 affected sibling pairs with AD available for analysis. The average age at onset was 74 years. The presence of APOE epsilon4 was strongly associated with AD. CONCLUSIONS: Both early-onset and late-onset familial AD occur in Caribbean Hispanics. In contrast to sporadic AD, late-onset familial AD among Caribbean Hispanics is strongly associated with APOE epsilon4. Future attempts to identify additional susceptibility genes should consider the effects of APOE epsilon4.

Desarrollo de biomodelos para la evaluación de la inmunidad secretora contra M. tuberculosis en ratones Babl/c / Development of Biomodels for the evaluation of the secretory immunity against M tuberculosis in Balb/c mice

Poco se ha estudiado acerca del papel de los anticuerpos específicos, presentes en las secreciones del aparato respiratorio, en la defensa contra patógenos intracelulares, como es el caso de las micobacterias causantes de la tuberculosis en el hombre: Micobacterium tuberculosis, bovis y africanum. Con el objetivo de desarrollar modelos adecuados para evaluar el posible papel de la inmunidad secretoria en la defensa contra la tuberculosis, se desarrollaron dos modelos animales con la utilización de un anticuerpo monoclonal IgA dirigido contra la proteína de 16 kD de M. tuberculosis y M. bovis. En el primer modelo se inocularon ratones Balb/c, por vía subcutánea al nivel de la nuca, con diferentes cantidades de células del hibridoma TBA61, productor de la IgA específica. En un segundo modelo, se inoculó por vía intraperitoneal líquido ascítico correspondiente a este hibridoma obtenido en ratón. En ambos casos se determinó, a diferentes tiempos, la concentración del monoclonal en saliva y sólo en suero para el segundo. En los dos modelos se demostró el paso del monoclonal a la saliva, donde alcanzó la máxima concentración: a los 21 días en los animales inoculados con el hibridoma, y a las 2 horas en saliva y suero en los animales inoculados con el líquido ascítico. Se sugiere, por su sencillez y mayor inocuidad, el uso del segundo modelo para la realización de estudios de reto por vía mucosal(AU)
