Gender roles and women’s mental health: their influence on the demand for psychological care
Authors: Toribio Caballero Sandra , Cardenal Hernáez Violeta , Ávila Espada Alejandro , Ovejero Bruna María Mercedes
Published: January 2022

The prevalence of certain diagnoses, such as eating disorders, depression, anxiety, and borderline personality disorder, is higher among women than among men. When it comes to women’s mental health, focusing on social aspects influencing the way women fall ill becomes crucial. Using a sample of 368 women, we studied the classification ability of a number of clinical variables and sociocultural factors (conformity to gender norms) in order to ascertain whether or not women were receiving psychological care and determine the importance of each of the variables when predicting which women were receiving therapy. Our results showed that women were more likely to be receiving psychological treatment when scoring high on certain clinical variables (such as Suicidal Ideation and Borderline Features) and on a number of variables related to conforming to gender norms (Care for Children, Nice in Relationships, and Sexual Fidelity). Therefore, we believe that integrating the gender perspective into educational, health-related, and psychological care programmes is essential so that gender roles can become more diverse and less constricting of people’s potential, resulting in improved health.

La prevalencia de determinados diagnósticos –trastorno de la conducta alimentaria, depresión, ansiedad y trastorno límite– es superior en mujeres que en hombres. Considerando la salud mental en mujeres, resulta imprescindible poner el foco en los aspectos sociales que influyen en la forma de enfermar. Se estudia en una muestra de 368 mujeres la capacidad de clasificación de algunas variables clínicas y factores socioculturales (conformidad con las normas de género) para determinar si una mujer está recibiendo asistencia psicológica o no, así como la importancia de cada una de esas variables a la hora de pronosticar qué mujeres estarían recibiendo terapia. Los resultados mostraron que cuando las mujeres puntúan alto en algunas variables clínicas (como Ideaciones Suicidas y Rasgos Límites) y en algunas relacionadas con conformidad con las normas de género (Cuidadora de Niños/as, Agradable en las relaciones y la Fidelidad Sexual) era más probable que estén recibiendo tratamiento psicológico. Por lo tanto, se considera que la inclusión de la perspectiva de género en programas de educativos, de salud y atención psicológica es fundamental para que los roles de género puedan ser más diversos y constriñan menos las potencialidades de las personas, lo que influirá en que tengan una mejor salud.

In this study, the psychometric properties of the Spanish version (Bakker et al., 2018) of the Job Crafting scale of Tims et al. (2012), was analyzed in a Latin American population. We applied the scale to a sample of 903 employees (42.6% women & 57.4% men) from Colombia and Ecuador. Reliability and validity were examined. The results of the confirmatory factor analysis showed an adequate fit both in Colombia (CFI = .916, TLI = .900, IFI = .917, RMSEA = .060) and in Ecuador (CFI = .918, TLI = .903, IFI = .919, RMSEA = .064), in the four-factor structure of the original scale. Evidence of validation, related to criterion for psychological well-being for the dimensions of increasing structural resources and increasing challenging demands, was found. The Spanish version of the scale demonstrates its usefulness for research in the Latin American context.

Work characteristics and occupational health: validation and proposal of a shortened version of the Work Design Questionnaire
Authors: García Izquierdo Antonio León , Castaño Pérez Ana M.
Published: January 2022

Interest in the study of work characteristics to explain how an individual's relationship with the work environment can lead to maladaptive responses has taken on renewed importance in the light of increasing concern for the development of healthy organizations and organizational diversity. This study aims to develop a shortened version of the Work Design Questionnaire (WDQ) with a view to facilitating its use and interpretation. The psychometric properties of this shorter questionnaire were tested in a multi-sectoral sample of workers in Spain, with due consideration given to the gender measurement invariance. For this purpose, we applied the questionnaire to a sample of 500 workers and analyzed the relationship between the answers provided to WDQ and specific occupational health variables (satisfaction, well-being and emotional exhaustion). Results showed adequate reliability and criterion-oriented validity for the shortened version of the WDQ, that is, the WDQ18-S, as well as evidence of factorial invariance across gender. We then discuss the results and their implications for the application of the WDQ in further research and the field of occupational health and psychosocial risks prevention.

El interés por el estudio de las características del trabajo para explicar cómo la relación de un individuo con el entorno laboral puede conducir a respuestas desadaptativas ha cobrado una importancia renovada a la luz de la creciente preocupación por el desarrollo de organizaciones saludables y por la diversidad organizacional. Este estudio tiene como objetivo desarrollar una versión abreviada del Work Design Questionnaire (WDQ) con el fin de facilitar su uso e interpretación en este contexto. Las propiedades psicométricas de este cuestionario reducido se probaron en una muestra multisectorial de trabajadores en España. Para ello, aplicamos el cuestionario a una muestra de 500 trabajadores y analizamos la relación entre las carácterísiticas del trabajo y las variables seleccionadas de salud ocupacional (satisfacción, bienestar y agotamiento emocional). Los resultados mostraron una fiabilidad y una validez orientada al criterio adecuadas para la versión abreviada del WDQ, esto es, el WDQ18-S, así como evidencia de invarianza factorial de género. Posteriormente se discuten los resultados y sus implicaciones para el uso del WDQ en el ámbito aplicado e investigador de la salud ocupacional y la prevención de riesgos laborales.
Before I Say Goodbye
Authors: Lucio-Villegas Spillard Iris Melanie
Published: January 2022

Alice Munro published in 2012 her last collection of short stories, Dear Life, which includes “Finale”, a quartet of stories introduced by the author in semiautobiographical terms. The relevance of the themes addressed is, as may be inferred, significant in relation to her life and previous work. In fact, they echo her first two collections of short stories —Dance of the Happy Shades (1968) and Lives of Girls and Women (1971)— not only in motifs and events, but also in style. This paper analyses and compares this last section —Munro’s conclusive contribution to the literary world— with her early work to establish joint features and similarities in order to support and extend the often-claimed autobiographical dimension of Munro’s fiction from this unexplored perspective. In addition, this process of analogy has recognised the author’s literary and emotional closure in relation to her mother, a hitherto elusive endeavour in her work.
Buying Behaviors of Polish Consumers During the Pandemic Lockdown – Research Results
Authors:   AGH University of Science and Technology in Krakow, Prymon-Ryś Ewa , Galarowicz Agnieszka ,   AGH University of Science and Technology in Krakow
Published: January 2022

Purpose: The purpose of the article is identification and evaluation of the most important changes that have occurred in the behavior of Polish consumers as a result of the pandemic lockdown introduced in 2020. The article presents the results of studies conducted during the epidemic restrictions from March 15 to May 4, 2020. Design/methodology/approach: The main aim of the research was to determine how these restrictions influenced the purchasing behavior and decisions made by consumers. In the polls, the technique of an internet survey was used, which was justified by the accepted form of remote communication imposed on the society in various spheres of activity. The subject of the research was the organization of free time, the organization of shopping in households, the frequency of purchases and the methods of shopping in stationary and online stores. Findings: The most important phenomena that have been observed include the growing importance of e-commerce and technologies supporting distance communication and online exchange. The share of FMCG in online purchases increased when compared with the pre-pandemic online purchases. Polish consumers reduced the frequency of purchases and limited their overall spending on everyday purchases. During the first wave of the pandemic, the crucial issue for consumers was time management as a result of increased professional and family responsibilities, or (a similar percentage of responses) of excess free time. Poles used information technologies – for communication, shopping, learning and entertainment, to cope with the imposed social isolation. This trend, as indicated by the results of subsequent studies, will continue. Research limitations/implications: The research was conducted at a particular moment of time, during the last 2 weeks of the first pandemic lockdown; therefore, the study cannot provide the measurement of observable effects of behavior changes during a longer time since the pandemic situation has been volatile. In the research, the snowball method of sampling, which has its own limitations, was adopted. Originality/value: The value of the article results from the outcomes of the survey conducted with the use of a research questionnaire originally designed for the purposes of this study and empirical research results obtained during the lockdown period, which allowed for observing changes in consumer behavior in real time.
Evolution of Consumption Behavior of Silver Singles in Poland
Authors:   University of Warsaw, Poland, Zalega Tomasz
Published: January 2022

Purpose: The purpose of the study is to analyze, based on the author’s own research, the relationship between lifestyle and selected consumer trends reflected in specific consumption behavior of silver singles. Design/methodology/approach: The analysis is based on a survey questionnaire administered between 1 February and 30 October 2019 in a sample of 2476 elderly people living alone in ten Polish cities of various populations and sizes. In accordance with the research assumptions, the sample included persons over 65 years of age who took independent consumption decisions in the market. This research method was chosen in view of the older age of respondents whose openness to new media often used in direct research is limited. Findings: The research shows that among the surveyed silver singles, men more often than women act in line with the cocooning and consumer ethnocentrism trends. It also reveals a strong correlation between cocooning and consumer ethnocentrism on the one hand and the level of education and monthly disposable income of silver singles on the other. As regards sustainable consumption, the proportion of silver singles who declared that they acted in line with that idea was much higher among women than men as well as among university graduates, those earning a monthly income of more than PLN 3000.00, and actively attending UTA courses. Research limitations/implications: Given the limited financial capacity, the study of consumer behavior matching the idea of cocooning, consumer ethnocentrism and sustainable consumption among silver singles was confined to a survey conducted in the biggest Polish cities. It was not possible to carry out research among single seniors living in rural areas. Following the conclusions made, they should not be treated as representative of the population of Polish silver singles. They only provide some insight into actual consumer behaviors of this consumer segment. Originality/value: This article is one of first publications in Poland that seek to provide some insight into consumption behaviors of Polish silver singles that are in line with the idea of selected alternative consumer trends.
Valuation of Livestock in Farms
Authors:   UTP University of Science and Technology in Bydgoszcz, Kica Piotr , Szczypa Piotr
Published: January 2022

Purpose: The aim of this article is to assess the possibility of applying the industry livestock valuation index as proposed by Karolina Pasula during the public defense of the doctoral dissertation “Directions and conditions for the standardization of accounting in agricultural enterprises” as an alternative method of valuation, taking into account sources of information and risk assessment on a farm. Methodology: The research process was divided into three main stages: (1) examining the possibility of applying the industry indicator for measuring biological assets proposed by K. Pasula for the valuation of livestock, i.e. pigs, as exemplified by a selected farm whose undertakings are known to the authors; (2) repeating the study from stage 1 on the valuation of dairy cattle as exemplified by the farm the activities of which are known to the authors; (3) on the basis of the conclusions of stage 1 and stage 2 studies, possible modification of the industry indicator for measuring biological assets, conducting research on a larger group of farms breeding livestock. Findings & value added: The conducted research confirmed the possibility of applying the analyzed ratio in the practice of entities that do not keep accounting books. The obtained results are characterized by high cognitive value as a measure of biological assets in relation to pigs. The valuation based on the industry measurement index in farms takes into account the risk which, as shown in the research, is an important factor influencing the value from the valuation.

Authors:   Wroclaw University of Economics and Business, Czerska Iwona
Published: January 2022

Purpose: This article aims to present the concept of corporate social responsibility as applied by healthcare entities in the conditions of the coronavirus pandemic. Design/methodology: The article is a literature review on corporate social responsibility, healthcare, management, and health economics. A critical analysis was performed based on the desk research method, using professional, scientific databases. The article consists of the following parts: introduction; research methodology; issues of corporate social responsibility in the current epidemic conditions, taking into account the areas and tools of CSR as applied by healthcare entities; literature study; limitations; conclusions, and practical implications. Findings: Running medical entities in a socially responsible manner is, in the context of the COVID-19 pandemic, perceived as a key and strategic action on the global market, contributing to the competitiveness of a given entity while caring for and shaping its image in the local environment. Research limitations/implications: A critical analysis identified several barriers to the study that could have influenced the overall picture of the considerations. Therefore, this article can be treated as a preliminary diagnosis of the topic under discussion. Subsequently, future analyses should extend to other entities and healthcare institutions to have a complete picture of their implementation of the CSR concept in pandemic conditions. Original value: The approach to the social responsibility of healthcare entities in the context of the COVID-19 pandemic based on the latest scientific studies, taking into account current reports in this regard by Polish and foreign authors, enriching the recent scientific achievements on social responsibility of the health sector and signaling the author’s contribution to the development of the discipline of management and quality sciences.
Contemporary Managerial Competences. Empirical Studies in the Field of Education
Authors:   Wydział  Zarządzania,  Uniwersytet  Warszawski, Postuła Agnieszka
Published: January 2022

The aim of the article is to identify and introduce divisions/typologies of contemporary managerial competences. The main research problem is to understand the processes taking place in business universities and their impact on shaping the next generations of managers. The article is based on the results of qualitative research inspired by the ethnography of the organization. 5-year research in the area of managerial education was conducted. The article presents competences important for various groups of the managerial education process. Specific breakdowns of these competences have been proposed. Reflections on the shaping of these competences in future managers as well as methods and ways of education are presented. The basis of empirical inquiry is qualitative material that cannot be generalized to the entire population. It is also inadvisable to draw sharp distinctions between the proposed concepts and typologies, as they are inherently fluid and ambiguous. The research was conducted over a period of 5 years, which is a unique advantage in the era of digitization and the ubiquitous domination of capitalist values. The research group is extremely broad and includes all participants / actors in the management education process.
The Markov Process as a Model of Migration Based on the Example of the Movement of Banknotes
Authors:   Faculty  of  Management,  University  of  Warsaw, Manikowski Arkadiusz
Published: January 2022

This paper presents a way of using the Markov chain model for the analysis of migration based on the example of banknote migration between regions in Poland. We have presented the application of the methodology for estimating one-step transition probabilities for the Markov chain based on macro-data gathered during the project conducted in the National Bank of Poland (NBP) in the period of December 2015–2018. We have shown the usefulness of state-aggregated Markov chain not only as a model of banknote migration but as migration in general. The banknotes are considered here as goods, so their migration is strictly related to, inter alia, the movement of people (commuting to work, business trips, etc.).Thus, the gravity-like properties of cash migration pointed to the gravity model as one of the most pervasive empirical models in regional science. Transition probability of the Markov chain expressing the attractive force between regions allows for estimating the gravity model for the identification of relevant reasons of note and, consequently, people migration.

Structural Social Capital Studies in Management and Organization Literature: A Bibliometric Network Study
Authors: Alan Hale , Köker Ali
Published: January 2022

Purpose: Many empirical and review studies have been performed in the management and organization literature from the structural social capital perspective. Since these studies focus on different topics periodically, we aimed to make a bibliometric analysis of the structural social capital literature that allows a regular, systematic, and quantitative evaluation of published articles in management and organization science to identify the underlying structure in this research area and to identify the main research themes of the scholarship. Methodology: The bibliographic matching technique was used for checking international databases to explore the main concepts and themes of the management and organization literature and to identify main themes in the research area. Therefore, this article offers a bibliometric analysis of the literature that allows for a regular, systematic, and quantitative evaluation of published articles to identify their underlying structure and to identify the main research themes in the scholarship. Research data were analyzed using the text mining method, which is a sub-branch of the data mining method and one of the most critical ways to analyze and process unstructured data. Findings: Structural social capital studies were examined in management and organization science databases in three periods forming four years. Although there are no completely different emerging themes, we noticed periodic differences and change in priority rankings. Moreover, we found that the subjects repeat every period with few new concepts. Implications: This research shows the main themes in the management and organization literature, where structural social capital elements are examined together, and covers all areas of management, organization and business science. Considering the main topics of the three periods of this research, there are similarities, namely the words that rank among the top in each period are “innovation,” “entrepreneurship,” “knowledge management,” “performance,” “leadership,” “technology,” and “human resources” and these themes are the most prominent. Originality/Value: This research presents an overview of all past studies that focus on the structural social capital present in social interactions. Since structural social capital influences management and organization literature, it is considered a valuable study and a guide for future research.
Investigating the Antecedents of Purchase Intention Toward Local Dairy Products: An Empirical Study Based on the SOR Model
Authors: Mkedder Nadjim , Bakır Mahmut , Lachachi Abdelheq
Published: January 2022

Purpose: The aim of this study was to investigate the antecedents of consumers’ purchase intention toward local dairy products. In doing so, this article delves into the relationships between perceived quality, perceived price, customer satisfaction, brand image, and customer purchase intention in the context of developing countries. Design/methodology/approach: Drawing on the stimulus-organism-response (SOR) framework, the research model was tested using the partial least squares structural equation modeling (PLS-SEM) technique with a questionnaire applied to 731 respondents from Saudi Arabia. Findings: The results showed that perceived quality, consumer satisfaction, and brand image have a positive impact on purchase intention, whereas perceived price could not explain purchase intention. Moreover, consumer satisfaction and brand image appeared to significantly mediate the relationships in the research model. Research limitations/implications: This article studies a specific country and local dairy consumption. One should be careful when generalizing the results to other food and country contexts. Originality/value: This study investigates consumer purchase intention specifically toward local dairy products, which was a matter underexplored in the literature as opposed to studies on a variety of other local products. Moreover, the article contributes to an extension of the SOR framework onto the body of literature regarding local products.

Published: January 2022

Purpose: In supply chains, creating a secure space for data production, sending, storing, and analysis has always been a critical issue. The main goal of this research was to evaluate the importance of various security criteria in an intelligent supply chain system. Methodology: The main data collection method was the expert survey. Experts validated the security criteria and sub-criteria. Then, the importance of these criteria was evaluated using the fuzzy analytic hierarchy process method. Findings: The results revealed that reliability and privacy with their sub-criteria were the most important ones among the obtained security criteria for IoT-based supply chain management. Practical implications: The research results can provide valuable insight for supply chains’ decision-makers. The findings can also be a good reference point for researchers who work on the IoT-based supply chain concept in other countries and sectors. Research limitations: Limitations of this study are the purposive sampling method and the limited scope of studied companies and sectors. Therefore, the article provides initial insight on the matter. Originality: The study presents the research problem from a new perspective and gives possible solutions for IoT-based supply chain management.

En el nombre del pueblo: consolidación autocrática subnacional en Cuba
Authors: Guach Hans Carrillo
Published: January 2022

The text analyzes the democraticity of decision-making processes on local level public affairs in Cuba, emphasizing the examination of citizens’ capacities to influence the conditions that sustain decision-making and public debates. The study reveals the mutual dependencies between elements that constitute an autocratic consolidation of politics. I describe and analyze dynamics that provide a peculiar understanding of the relationship between real autocratization and formal democratization at the local level in Cuba, based on the study of a medium-sized city (Cárdenas), the application of qualitative methods (such as the analysis of documents and semi-structured interviews), and the review of previous studies.
La ilusión de una región de clases medias: el caso de Uruguay
Authors: Álvarez-Rivadulla María José , Bogliaccini Juan , Queirolo Rosario , Rossel Cecilia
Published: January 2022

The expansion of middle-income sectors has, in recent years, drawn the attention of academia, international organizations, and governments. However, more recently, several studies have pointed to the vulnerability of these sectors. Based on household surveys, this paper analyzes the evolution of the middle classes in Uruguay in recent decades (1993-2016) using two complementary measures: one based on income and the other on occupation. The results suggest that the change in income levels that characterized the period did not result in a change in the structure of employment and human capital, and they alert about the vulnerability of the middle classes.
Formulations
Authors: Witt Andrew
Published: January 2022

An investigation of mathematics as it was drawn, encoded, imagined, and interpreted by architects on the eve of digitization in the mid-twentieth century.

In Formulations, Andrew Witt examines the visual, methodological, and cultural intersections between architecture and mathematics. The linkages Witt explores involve not the mystic transcendence of numbers invoked throughout architectural history, but rather architecture's encounters with a range of calculational systems—techniques that architects inventively retooled for design. Witt offers a catalog of mid-twentieth-century practices of mathematical drawing and calculation in design that preceded and anticipated digitization as well as an account of the formal compendia that became a cultural currency shared between modern mathematicians and modern architects.

Witt presents a series of extensively illustrated “biographies of method”—episodes that chart the myriad ways in which mathematics, particularly the mathematical notion of modeling and drawing, was spliced into the creative practice of design. These include early drawing machines that mechanized curvature; the incorporation of geometric maquettes—“theorems made flesh”—into the toolbox of design; the virtualization of buildings and landscapes through surveyed triangulation and photogrammetry; formal and functional topology; stereoscopic drawing; the economic implications of cubic matrices; and a strange synthesis of the technological, mineral, and biological: crystallographic design.

Trained in both architecture and mathematics, Witt uses mathematics as a lens through which to understand the relationship between architecture and a much broader set of sciences and visual techniques. Through an intercultural exchange with other disciplines, he argues, architecture adapted not only the shapes and surfaces of mathematics but also its values and epistemic ideals.
Myelinating Schwann cells and Netrin-1 control intra-nervous vascularization of the developing mouse sciatic nerve

Published: January 2022

Peripheral nerves are vascularized by a dense network of blood vessels to guarantee their complex function. Despite the crucial role of vascularization to ensure nerve homeostasis and regeneration, the mechanisms governing nerve invasion by blood vessels remain poorly understood. We found, in mice, that the sciatic nerve invasion by blood vessels begins around embryonic day 16 and continues until birth. Interestingly, intra-nervous blood vessel density significantly decreases during post-natal period, starting from P10. We show that, while the axon guidance molecule Netrin-1 promotes nerve invasion by blood vessels via the endothelial receptor UNC5B during embryogenesis, myelinated Schwann cells negatively control intra-nervous vascularization during post-natal period.
A multi-objective algorithm for virtual machine placement in cloud environments using a hybrid of particle swarm optimization and flower pollination optimization
Authors: Mejahed Sara , Elshrkawey M
Published: January 2022

The demand for virtual machine requests has increased recently due to the growing number of users and applications. Therefore, virtual machine placement (VMP) is now critical for the provision of efficient resource management in cloud data centers. The VMP process considers the placement of a set of virtual machines onto a set of physical machines, in accordance with a set of criteria. The optimal solution for multi-objective VMP can be determined by using a fitness function that combines the objectives. This paper proposes a novel model to enhance the performance of the VMP decision-making process. Placement decisions are made based on a fitness function that combines three criteria: placement time, power consumption, and resource wastage. The proposed model aims to satisfy minimum values for the three objectives for placement onto all available physical machines. To optimize the VMP solution, the proposed fitness function was implemented using three optimization algorithms: particle swarm optimization with Lévy flight (PSOLF), flower pollination optimization (FPO), and a proposed hybrid algorithm (HPSOLF-FPO). Each algorithm was tested experimentally. The results of the comparative study between the three algorithms show that the hybrid algorithm has the strongest performance. Moreover, the proposed algorithm was tested against the bin packing best fit strategy. The results show that the proposed algorithm outperforms the best fit strategy in total server utilization.

Published: January 2022

Urban trees are important to maintain biodiversity and, therefore, need public acceptance. Few studies, however, have addressed the topic of social acceptability of old trees. The aim of this research was to examine city residents’ perception of old trees, including hollow-bearing ones, mainly in the aspect of safety and aesthetics. A total of 448 Warsaw municipal forest’ users expressed their opinions by completing an online questionnaire. Several methods were used to analyse the results of the study: the Chi-square test of independence, the Kruskal–Wallis H test, the Mann–Whitney U test and the Quartimax method of factor rotation analysis. The results revealed a correlation between the frequency of forest visits and the level of sensitivity toward old trees, which translates to less radical notion of danger and less radical decisions about cutting such trees down. Age of the respondents (56+) was a factor contributing to higher willingness to protect and care for old trees. The results also indicated that outdoor activity in the urban forest may increase ancient trees acceptance by developing emotional connection with them, and eventually contribute to their protection.

Lake Baikal phage communities are important for lake ecosystem functioning. Here we describe the diversity of T4-bacteriophage associated with the bacterial fraction of filtered water samples collected from the pelagic zone, coastal zone and shallow bays. Although the study of the diversity of phages for the g23 gene has been carried out at Lake Baikal for more than ten years, shallow bays that comprise a significant part of the lake’s area have been neglected, and this gene has not previously been studied in the bacterial fraction. Phage communities were probed using amplicon sequencing methods targeting the gene of major capsid protein (g23) and compared phylogenetically across sample locations and with sequences previously retrieved from non-bacterial fractions (<0.2 um) and biofilms (non-fractionated). In this study, we examined six water samples, in which 24 to 74 viral OTUs were obtained. The sequences from shallow bays largely differed from those in the pelagic and coastal samples and formed individual subcluster in the UPGMA tree that was obtained from the comparison of phylogenetic distances of g23 sequence sets from various ecosystems, reflecting differences in viral communities depending on the productivity of various sites of Lake Baikal. According to the RefSeq database, from 58.3 to 73% of sequences of each sample had cultivated closest relatives belonging to cyanophages. In this study, for phylogenetic analysis, we chose the closest relatives not only from the RefSeq and GenBank NR databases but also from two marine and one freshwater viromes: eutrophic Osaka Bay (Japan), oligotrophic area of the Pacific Ocean (Station ALOHA) and mesotrophic and ancient Lake Biwa (Japan), which allowed us to more fully compare the diversity of marine and freshwater phages. The identity with marine sequences at the amino acid level ranged from 35 to 80%, and with the sequences from the viral fraction and bacterial one from Lake Biwa—from 35.3 to 98% and from 33.9 to 89.1%, respectively. Therefore, the sequences from marine viromes had a greater difference than those from freshwater viromes, which may indicate a close relationship between freshwater viruses and differences from marine viruses.
Effects of different intensities of long-term grazing on plant diversity, biomass and carbon stock in alpine shrubland on the Qinghai-Tibetan Plateau
Authors: Wang Jinlan , Li Wen , Cao Wenxia , Wang Shilin
Published: January 2022

Grazing is the main grassland management strategy applied in alpine shrubland ecosystems on the Qinghai-Tibetan Plateau. However, how different intensities of long-term grazing affect plant diversity, biomass accumulation and carbon (C) stock in these ecosystems is poorly understood. In this study, alpine shrubland with different long-term (more than 30 years) grazing intensities (excluded from grazing for 5 years (EX), light grazing (LG), moderate grazing (MG) and heavy grazing (HG)) on the Qinghai-Tibetan Plateau were selected to study changes in plant diversity, aboveground biomass and C accumulation, as well as distribution of C stock among biomass components and soil depths. A structural equation model was used to illustrate the impact of grazing on the soil carbon stock (SOC). The results showed that the Shannon–Wiener diversity index and richness index of herbaceous plants, shrubs, and communities first significantly increased and then decreased with increasing grazing intensity, reaching maxima at the LG site. The aboveground and belowground and litter biomass of understory herbaceous plants, shrubs and communities decreased with increasing grazing intensity, reaching maxima at the EX site. The aboveground and belowground biomass C storage decreased with increasing grazing intensity, reaching maxima at the EX site. The SOC stock and total ecosystem C stock decreased with increasing grazing intensity, reaching maxima at the EX and LG sites. A structural equation model showed that grazing-induced changes in the belowground biomass of understory herbaceous plants greatly contributed to the SOC stock decrease. Thus, considering the utilization and renewal of grassland resources, as well as local economic benefits and ecological effects, LG may be a more rational grazing intensity for species diversity conservation and ecosystem C sequestration in alpine shrubland. Our results provide new insights for incorporating grazing intensity into shrub ecosystem C stock and optimizing grazing management and grassland ecosystem C management.

La COVID-19 ha generado un nuevo desafío global en términos de la seguridad de los periodistas. El epicentro de la pandemia se trasladó en junio de 2020 a América Latina, donde el desconocimiento sobre el coronavirus, unido a la pluralidad de respuestas políticas y la diversidad de mecanismos puestos en funcionamiento por los medios y las empresas de comunicación han afectado directamente al ejercicio profesional. Este artículo busca analizar las principales consecuencias laborales y emocionales para los profesionales de la información desde México hasta Argentina durante los primeros 100 días de la COVID-19 en la región, por medio de un cuestionario distribuido entre las 18 organizaciones afiliadas de la Federación Internacional de Periodistas en América Latina, pertenecientes a 16 países (N=95). El agravamiento de las debilidades estructurales del periodismo latinoamericano, unido a la precarización y a los efectos del teletrabajo han sido algunos de los principales resultados del estudio, que será discutido con otros similares realizados a escala nacional en Argentina y Brasil en futuras investigaciones. Las conclusiones de este trabajo, que representa a un grupo determinado de estudio, ofrecerán futuras líneas de investigación para un proceso y universo más amplio, que deberán ser tenidas en cuenta para mejorar los protocolos de protección de los periodistas freelance y dependientes de medios públicos, privados y comunitarios en América Latina.

Esta investigación tiene como objetivo determinar indicadores clave para evaluar la capacidad de transparencia, autorregulación y participación de los usuarios, las tres dimensiones de la accountability. Se adoptó un triple punto de partida metodológico: revisión sistemática de literatura sobre indicadores de accountability y sus características, un mapeo de medios de referencia con indicadores de accountability, y evaluación de medios. Se obtuvo un sistema de 11 indicadores clave para medir y establecer comparaciones entre sitios web de medios de comunicación y determinar si satisfacen las tres dimensiones clave de la rendición de cuentas y los elementos asociados. Dicho sistema puede ser aplicado en múltiples escenarios para fomentar un periodismo de calidad.

El objetivo de este artículo es comparar el tratamiento mediático de dos movimientos sociales españoles: el 15-M (o Indignados) y la Plataforma de Afectados por la Hipoteca (PAH). La cobertura periodística del 15-M ha sido objeto de muchos estudios. Sin embargo, el análisis comparativo ha sido muy poco utilizado, a pesar de sus posibilidades para ofrecer información relevante sobre las variables que pueden influir en cómo los medios retratan los movimientos sociales. Con este propósito, se ha aplicado un análisis de contenido cuantitativo a una muestra de noticias publicadas en las ediciones digitales de los medios de comunicación más relevantes de España. Los resultados cuestionan el paradigma de la protesta, dado el trato mediático mayoritariamente positivo o neutral recibido por ambos movimientos sociales. No obstante, la representación de la PAH es significativamente más favorable, lo que se deriva de la combinación de tácticas disruptivas (para atraer a los medios) e institucionales (para obtener un trato positivo). Esta combinación se refuerza mediante la estrategia comunicativa de la PAH.

Esta investigación analiza el impacto en las redes sociales del spin-off #Luimelia, emitido en febrero-marzo de 2020 como una extensión de narrativa transmedia de una de las tramas de la ficción española Amar es para siempre, la más vista a diario en España. Los fans bautizaron con esta etiqueta la relación afectivoamorosa entre dos mujeres, visibilizando de forma positiva las relaciones lésbicas en una serie de ficción. El éxito de su historia da lugar a un nuevo producto transmedia, que fomenta las sinergias entre plataformas y convierte a las redes sociales en un elemento narrativo más. A partir del análisis cuantitativo de su repercusión en Twitter y de tres entrevistas en profundidad semiestructuradas a los dos guionistas de la serie y a una profesional responsable de la medición de audiencias, se revela cómo la movilización de los fans fue decisiva para el surgimiento de #Luimelia y cómo su estrategia de redes contribuye al desarrollo de la trama y a construir los personajes protagonistas.

Due to increased competition enterprises have sought alternatives to improve their processes and increase the quality of their products and services. The enterprises of construction sector are related to the buildings construction. They have adopted Quality Management System (QMS) to improve their processes and to fill the demands of the market. Among the existing QMS, the Brazilian Program of Habitat Quality and Productivity (PBQP-H/Siac) has distinguished itself by offering benefits that are favorable to the enterprises in this segment. However, unlike medium and large enterprises, the Micro and Small enterprises (MSEs) have limited financial resources, lack on quality management, and others obstacles. MSEs have fitted their quality implementation to match with the larger construction enterprises, to better competition and to get opportunities in the market. Because of this, the present paper proposes an approach to self-evaluation requirements of PBQP-H/Siac, using fuzzy logic as a measurement tool. The fuzzy logic will formalized the assessed requirement, providing better definition on decision making. The approach exposed as a simulation based on real case to demonstrate their applicability. As a result the approach determines the degree of formalization of the desired level.
