O termo competitividade para as empresas da atualidade é abordado como um fator essencial para que permaneçam no mercado. Para manterem-se ativas, elas precisam ser hábeis ao identificarem as necessidades dos seus clientes e, na mesma medida, solucioná-las. Neste artigo, analisamos a qualidade de serviços prestados por uma empresa contábil da região de Almenara/MG, utilizando a metodologia Servqual. Utilizamos o Servqual como instrumento de pesquisa com a finalidade de analisar e conhecer, a partir das dimensões propostas pelo método, os pontos fortes e fracos dos serviços oferecidos pela empresa. Por conseguinte, apresentaremos a análise dos dados obtidos através das pesquisas aplicadas a fim de expor as propostas de tomadas de decisões quanto aos serviços prestados. Assim, concluímos que a empresa precisa considerar algumas questões de aparência visual, tempo de atendimento, praticidade para o cliente e capacitação aos colaboradores para que atendam todas as expectativas do seu público, visto que o mensurador de qualidade em todas as médias finais das dimensões foi negativo, o que implicou na necessidade de medidas para melhorias.

Published: October 2021

Dada a atual quantidade de resíduos ambientalmente nocivos, é fundamental a consciencialização individual e das organizações face à política dos “3R’s”, a redução, a reutilização e a reciclagem. Neste trabalho pretende-se aferir os conhecimentos e comportamentos em relação à prática dos “3R’s” na comunidade do Instituto Politécnico da Guarda (IPG), em Portugal, e identificar situações que carecem de medidas pró-ambientais. Realizou-se, para isso, um estudo transversal, quantitativo e descritivo baseado num instrumento de recolha de dados, distribuído via correio eletrónico, que obteve a participação de 342 indivíduos.Mais de 50% dos participantes manifestaram ter conhecimentos sobre o tema “3R’s”. Concluiu-se que 99,1% dos indivíduos optaram “Algumas vezes” a “Sempre” pela atitude adequada face aos “3R’s”. Para a maioria não existe uma boa sinalização dos pontos de reciclagem no IPG (51,2%), nem uma política proactiva face aos resíduos (54,1%).Pode concluir-se que os conhecimentos e comportamentos dos respondentes são francamente positivos, mas identificaram-se pontos que exigem medidas de intervenção.
Comunicazione specialistica e multilinguismo: sfide per il linguaggio medico in Ticino
Authors: Lobin Antje
Published: October 2021

Il presente contributo è dedicato alla Svizzera italiana e individua una lacuna all’interfaccia della ricerca sui linguaggi specialistici, del multilinguismo e della linguistica di contatto. Per molto tempo in Ticino non esisteva una facoltà di medicina e farmacia, motivo per cui la formazione si è svolta nella parte tedesca o francofona del Paese o in Italia. La situazione sta cambiando, in quanto dal 2020 i futuri medici possono conseguire un master triennale in medicina presso l’Università della Svizzera italiana. I corsi si svolgono in inglese. Il programma di bachelor si svolge, in parte in tedesco, in parte in inglese, presso le università partner di lingua tedesca di Basilea e Zurigo. In passato, questa particolare situazione di formazione medica ha già portato ad una serie di peculiarità nel linguaggio della pratica medica quotidiana. In questo contributo si delinea la situazione della ricerca per quanto riguarda l’italiano in Ticino e si presenta il profilo della lingua italiana in quest’area. Successivamente si passa alla visione esemplificativa delle specificità della comunicazione medica in Ticino e si traccia un programma di ricerca, che permetterebbe di registrare sistematicamente lo stato specifico tra pianificazione linguistica e norma d’uso fluttuante, i principi della formazione analogica, i principali fattori d’influenza così come le frequenze delle denominazioni concorrenti.

As digital media permeate all aspects of our lives, achieving distance learning today, and in the future, can be considered inevitable, for the effectiveness of which it is necessary to provide appropriate preconditions. After the sudden outbreak of the pandemic in late 2019 and early 2020 caused by the appearance of the COVID19 virus, faculties around the world were forced to reorganize and move to online classes as soon as possible, in order to enable students to continue the academic year. The aim of this paper is to point out the basic assumptions of successful online teaching in higher education, which is assumed to continue to exist in some form after the end of the pandemic. The given assumptions will be presented in the form of pointing out the specifics of online teaching, which are significantly related to the success of students in it. It is possible to single out three groups of such specifics: individual specifics of the students themselves, characteristics of online teaching and characteristics of the higher education institution, which are described in more detail in the paper. Such teaching primarily implies adequate preparation of teachers and students in terms of developing appropriate individual competencies. In addition, an important factor of successful online teaching implies the existence of appropriate institutional support at the level of a specific higher education institution in its implementation. The given recommendations can be a good starting point for the implementation and improvement of the quality of online teaching in higher education in our country.

Published: October 2021

The 2020 crisis caused by the global COVID-19 pandemic brought the current and emerging weaknesses of the education system in both developed countries and countries in transition to the surface. This paper focuses on a comparative overview of the sector of higher education, especially in terms of the possibilities for achieving equality of educational opportunity, mobility, quality of scientific research, and education quality in general. We conducted an analysis of available theoretical papers, empirical studies, and reports that focus on the impact of the pandemic on institutions of higher education, the process itself, and the results of online teaching/learning, research and internationalization of education. The results of the analysis indicate differentiated responses of institutions of higher education to the new situation and the changed social context with regard to all observed aspects. Previous studies and analyses should indicate directions for post-pandemic reactions of institutions of higher education, so they could adequately and flexibly respond to global crises and changes in the future.

Authors: Wahyudi Muhammad , Hidayat Abdul Rasyid
Published: October 2021

The Student Teams Achievement Division (STAD) strategy is very important in learning Arabic because this method is student-centered, active, cooperative, and helps each other complete assignments through discussion. The purpose of this study was to explore the literature on the STAD method in Arabic subjects. This paper was a literature study. The data showed that the STAD is simpler than other cooperative learning strategies; it is a good model for teachers who are just starting to apply cooperative strategies in learning. The teachers should give attention to each stage in STAD in innovative ways so that students do not feel bored and can increase their learning motivation and learning outcomes.

Published: October 2021

The present study aimed to design a strategic human resource management model in the Ministry of Science with emphasis on strategic thinking. The statistical population of the present study consisted of two groups, the first group included experts familiar with the subject under study and the second group included faculty members at universities in the southeast region of the country (Kerman, Sistan and Baluchestan, Hormozgan). Stratified sampling method in line with the volume of classes was also performed. At last, a total of 340 questionnaires were completed and collected. Kaiser-Meyer-Olkin (KMO) criteria were used to ensure the validity of the data and to examine the accuracy of the sampling before the factor analysis. Based on the findings, the value of KMO on strategic thinking, strategic human resources management were 0.903 and 0.913, respectively, which is an acceptable value. Data were analyzed using SPSS software version 23 and AMOS version 23. In the present study, a significance level was considered 0.05. Statistical methods such as one-sample t-test, confirmatory factor analysis and structural equations were used to investigate the research questions. Results from the structural equation model demonstrated that there was a significant relationship between strategic thinking and strategic human resource management.

Published: October 2021

The physical and cognitive sequelae resulting in functional disabilities after Stroke has an influence on the quality of life (QoL) of stroke survivors. The objective of the study was to assess stroke specific quality of life among stroke survivors. A Quantitative descriptive study in which 50 stroke survivors attending the stroke OPD of a tertiary care hospital after a month were taken using convenient sampling. Their Quality of Life (QoL) was assessed in 12 domains using Stroke Specific Quality of Life (SS-QOL). The Data was analyzed using descriptive and inferential statistics. A fairly good QoL was seen among the study subjects. The mean SS-QOL was 174.86 with a SD of +/- 46.81 in a maximum score of 245 (71.37%). The most affected domain in SS-QOL was social role (59.36%), followed by family role (61.72%) and the least affected were vision (82.26%) and language (86.24%). The poor QoL in social roles and family roles clearly indicates the necessity to strengthen the stroke rehabilitative services in our community.
Examining the Influence of Genes Linked to Comorbidities on the Development of Diabetic Retinopathy
Authors: Das Ishani , DeMuth Larry
Published: October 2021

Diabetic retinopathy (DR) is a complication in diabetic patients that can cause vision loss and even blindness12 {Healthline}. The condition causes bleeding in the blood vessels of the retina and ultimately interferes with the capture of photons and the transmission of neural signals to the brain3 {National Eye Institute}. Unfortunately, there is no cure available for the approximately 200,000 US citizens currently affected by DR8 {Lucas Research}. Current treatments are merely palliative and rarely restore vision. The best approach to combating DR is prevention. Understanding the root genetic causal links of DR is crucial to developing effective prevention plans. 

Unlike Huntington’s Disease, which has well defined genetic origins, no single gene has been pinpointed as a causative factor for DR, despite having been extensively researched. Since diabetes alone isn’t enough to predict the progression to DR4{NCBI}, one can hypothesize that a combination of diabetes and at least one other comorbidity, such as high blood pressure, high cholesterol, etc., may be essential to the development of DR. In this way, single nucleotide polymorphisms (SNPs) associated with other comorbidities could increase the likelihood of retinal bleeding in diabetic populations. The identification of these SNPs would offer valuable insight into the development of a genetically-driven prevention plan for diabetic retinopathy.
Foreign direct investment and export performance in Ghana: Modeling uncertainty using Bayesian Model Selection Approach
Authors: Ahiakpor Ferdinand , Brafu-Insaidoo William Gabriel , Obeng Camara Kwasi , Wiafe Emmanuel Agyapong
Published: October 2021

This paper employs the Bayesian Model Selection (BMS) to determine the link between Foreign Direct Investment (FDI) and export performance in Ghana. The BMS enables us to consider a large number of potential explanatory variables and deal with the issue of model uncertainty. The study revealed positive effect of FDI on export performance but not as a major driver of export growth in Ghana. However, the effect of domestic savings, trade liberalisation and infrastructure development are found to have stronger effect on export performance than FDI inflows. The study recommends government policies should be geared towards improving domestic savings and the liberalization of the economy towards international trade.
Bringing the critical into doctoral supervision: What can we learn from debates about epistemic justice and the languaging of research?
Authors: Fay Richard , Andrews Jane , Huang Zhuo Min , White Ross
Published: October 2021

In this article, we discuss how, as supervisors in largely Anglophone university contexts in England, we are trying to develop supervisory practices informed by the discussions of epistemic (in)justice and the languaging of research. Having rehearsed these discussions, and considered the opportunities provided by research integrity policy formulations in our context, we conceptualise doctoral supervision critically, interculturally, and ecologically. We then report our efforts to shape the supervisory agenda so that, in the local spaces available to us, the shaping influences of the epistemic and linguistic in the wider research environment are problematised. In particular, we focus on two strands of our thinking, namely: a) the implications of epistemic hierarchies and the value of an intercultural ethic for the transknowledging at the heart of doctoral research; and b) the role of language(s) in research and the value of a translingual researcher mindset. In both strands, our thinking has moved from a more instrumental to a more critical stance regarding research, researcher thinking, and supervision. This development highlights some of the complexities involved in developing critical intercultural praxis for doctoral supervision. We conclude with recommendations—aimed at all those involved in doctoral supervision—to facilitate a critical intercultural supervisory culture.
Antecedents and Consequences of Social Adjustment of Undergraduate Students in Thailand: A Meta-Analysis Study
Authors: Ruangying Jiraporn
Published: October 2021

Social adjustment of undergraduate students is an issue that every educational institution worldwide regards as essential; this also includes educational institutions in Thailand. The systematic study, collection, and synthesis of antecedent factors affecting student’s social adjustment are, therefore, necessary as the data obtained from the abundance of research available can lead to new findings which can be used to design, strategize and promote students’ social adjustment, effectively addressing the social adjustment issues of students which have long been problematic. Therefore, this research’s objective is to synthesize available knowledge in the dimension of antecedent factors and consequences regarding to undergraduate students’ social adjustment in Thailand through the examination of various research publications available in the past 10 years (from year A.D. 2009-2019) through meta-analysis. Research that was used to synthesize 50 studies. Research results found that the individual’s internal factors affected student social adjustment the most. The variable of self-control has the largest average effect size. The variables of self-reliance and abstraction have negative consequences and large average effect sizes. Among the factors in the category of individuals’ external factors, the variable of participation in student activities had the largest average effect size, followed by interpersonal relationships, and participation in religious activities, respectively. In addition, under demographic factors, the variable of student age had the largest average effect size, followed by academic achievement, gender, source of funding received, and religion, respectively. These findings can be helpful in furthering strategic planning to ameliorate the social adjustment of students in higher education.

La influencia de la industrialización en la obra de Gerrit Rietveld. Del módulo al Kernhuis
Authors: Arribas Blanco Ruth
Published: October 2021

The appearance of new paradigms in the early 20th century due to the impact of industrialisation unleashed a reformulation of the strategies used for building from the beginning to the creative phase. This paper examines in depth how architect Gerrit Rietveld used industrialisation and the strategy used in his work at the time of the so-called Functionalist Period by analysing his different projects. Without an exhaustive analysis of all his work, the aim was to get to know another facet of the Utrecht architect apart from his best known neoplastic compositional facet, related to his preoccupation with responding to social needs by the efficient organization of space, making use of industrial products and with a special interest in the constructive aspect of his projects. Finally, Rietveld’s figure is associated with that of Habraken and the connections between both Dutch architects are analysed.
Las casas cuartel de la DGRD para la Guardia Civil: un modelo adaptado para la propaganda
Authors: Pinzón-Ayala Daniel
Published: October 2021

The Civil Guard barracks, promoted by the Directorate-General of Devastated Regions [Dirección General de Regiones Devastadas, DGRD] (1939-1957), are an exception within the general marginality of this hybrid architecture in architectural historiography. However, such a prominence has led to a distorted and partial approach to the architecture of these barracks, ignoring the contemporary production of the Civil Guard’s technical services. This is the first study that deals with the post-war promotion of barracks, offering an analysis that sheds light on the interdependencies and contributions made by each organisation. The methodology is based on a bibliographical review, which includes the Reconstrucción journal, the consultation of the projects in the archives that hold the documentation of both organisations and the comparative analysis of their productions. This paper aims to show how the DGRD based the promotion of its barracks on the models created by the architects attached to the Civil Guard, taking them directly and adapting them to its propagandistic interests according to Franco’s ideology using strategic implantation, a commitment to specific typologies, excessive ornamentation and the emphasis on a collective way of life.
Estética e política no Brasil contemporâneo: Terra em transe e Maranhão 66 revisitados
Authors: Vaz Alexandre Fernandez
Published: October 2021

O artigo revisita os filmes Terra em Transe e Maranhão 66, de Glauber Rocha, documentos estético-políticos dos anos 1960 no Brasil, que ganham novas cores com o desenrolar histórico. Para tanto, considera a tradição dialética, representada aqui por Theodor W. Adorno, entre forma social e expressão estética. Em relação a isso, analisa opções construtivas, narrativas e técnicas dos filmes, observando-os como obras que amadurecem com o tempo, apontando, retrospectivamente, os impasses nacionais. Ao mesmo tempo, traça, em composição com os filmes, o contexto histórico que foi se desenrolando nas décadas seguintes a eles. O atual ambiente antidemocrático, bem como a ascensão de Luís Inácio Lula da Silva ao cenário nacional, e o percurso emblemático de José Sarney, oferecem a encarnação social do que os filmes, expressivamente, apresentam. Conclui apontando o impasse e a necessidade do encontro de uma iluminação estética que seja capaz de estar à altura das agruras do presente.

Knowledge, attitudes and perceptions of health care users towards HIV self-testing at selected Gateway clinics at eThekwini District, KwaZulu-Natal
Authors:   , Gumede Sibongiseni Daphney
Published: October 2021

Background Human immunodeficiency virus (HIV) testing, treatment and prevention programmes have been initiated and implemented, but nearly 19 million of the 35 million people globally who are living with HIV do not know they have it. A new and powerful movement called 90-90-90 has been set in motion where the target is that by the year 2020, 90% of all people should know their HIV status, 90% of those testing HIV positive should be commenced on lifelong antiretroviral treatment and 90% of the people receiving treatment should be virally suppressed. It is argued the new innovative HIV self-testing strategy can increase the uptake of HIV testing among key populations and the general public. Aim of the study The aim of the study was to assess health care users’ knowledge, attitudes and perceptions towards HIV self-testing at selected Gateway clinics in eThekwini District, KwaZulu-Natal. Methodology A quantitative, non-experimental descriptive design was used to determine knowledge, attitudes and perceptions of health care users at three selected Gateway clinics in eThekwini Health District. The researcher requested permission and was granted to conduct the study from all the relevant stakeholders. Human rights were protected and ethical considerations were adhered to throughout the research process. The convenience sample was 442 participants with a minimum of 98 and a maximum of 246 participants sampled from each of the three study sites. A survey questionnaire was used to collect data. Version 23 of SPSS was used to analyse data. Graphs and tables were used to represent frequencies. Inferential statistical were used to test whether any of the response options were selected significantly more or less than others Results Results of the study revealed that health care users had a reasonable knowledge of HIV self-testing and there were indications that they would use it if it was made freely available to the public and was properly regulated. Generally, there were indications that health care users had positive attitudes towards HIV self-testing. It was seen as a good idea as it can be performed in the privacy of one’s home and the person would be first to know about the results. Results also revealed that there could be more people who would know their HIV status and people could test more frequently. There were perceptions that there would be no difficulty in performing an HIV self-test. The lack of pre-test counselling, false negative results, possible coercion and sale of unregulated testing kits seemed to be issues of concern that require addressing if HIV self-testing is to be promulgated.

Abstract. Accurate sub-city fine particulate matter (PM2.5) estimates could improve epidemiological and health-impact studies in cities with heterogeneous distributions of PM2.5, yet most cities globally lack the monitoring density necessary for sub-city-scale estimates. To estimate spatiotemporal variability in PM2.5, we use machine learning (Random Forests; RFs) and concurrent PM2.5 and AOD measurements from the Citizen Enabled Aerosol Measurements for Satellites (CEAMS) low-cost sensor network as well as PM2.5 measurements from the Environmental Protection Agency’s (EPA) reference monitors during wintertime in Denver, CO, USA. The RFs predicted PM2.5 in a 5-fold cross validation (CV) with relatively high skill (95% confidence interval R2=0.74–0.84 for CEAMS; R2=0.68–0.75 for EPA) though the models were aided by the spatiotemporal autocorrelation of the PM2.5 measurements. We found that the most important predictors of PM2.5 were factors associated with pooling of pollution in wintertime, such as low planetary boundary layer heights (PBLH), stagnant wind conditions, and, to a lesser degree, elevation. In general, spatial predictors were less important than spatiotemporal predictors because temporal variability exceeded spatial variability in our dataset. Finally, although concurrent AOD was an important predictor in our RF model for hourly PM2.5, it did not improve model performance with high statistical significance. Regardless, we found that low-cost PM2.5 measurements incorporated into an RF model were useful in interpreting meteorological and geographic drivers of PM2.5 over wintertime Denver. We also explored how the RF model performance and interpretation changes based on different model configurations and data processing.
The Lehtinen-Pirjola Method Modified for Efficient Modelling of Geomagnetically Induced Currents in Multiple Voltage Levels of a Power Network
Authors: Pirjola Risto J. , Boteler David H. , Tuck Loughlin , Marsal Santi
Published: October 2021

Abstract. The need for accurate assessment of the geomagnetic hazard to power systems is driving a requirement to model geomagnetically induced currents (GIC) in multiple voltage levels of a power network. The Lehtinen-Pirjola method for modelling GIC is widely used but was developed when the main aim was to model GIC in only the highest voltage level of a power network. Here we present a modification to the Lehtinen-Pirjola (LP) method designed to provide an efficient method for modelling GIC in multiple voltage levels. The LP method calculates the GIC flow to ground from each node. However, with a network involving multiple voltage levels many of the nodes are ungrounded, i.e. have infinite resistance to ground which is numerically inconvenient. The new modified Lehtinen-Pirjola (LPm) method replaces the earthing impedance matrix [Ze] with the corresponding earthing admittance matrix [Ye] in which the ungrounded nodes have zero admittance to ground. This is combined with the network admittance matrix [Yn] to give a combined matrix ([Yn]+[Ye]), which is a sparse symmetric positive definite matrix allowing efficient techniques, such as Cholesky decomposition, to be used to provide the nodal voltages. The nodal voltages are then used to calculate the GIC in the transformer windings and the transmission lines of the power network. The LPm method with Cholesky decomposition also provides an efficient method for calculating GIC at multiple time steps. Finally, the paper shows how software for the LP method can be easily converted to the LPm method and provides examples of calculations using the LPm method.
Field-scale CH4 emission at a subarctic mire with heterogeneous permafrost thaw status

Published: October 2021

Abstract. The Arctic is exposed to even faster temperature changes than most other
areas on Earth. Constantly increasing temperature will lead to thawing
permafrost and changes in the methane (CH4) emissions from wetlands.
One of the places exposed to those changes is the Abisko–Stordalen Mire in
northern Sweden, where climate and vegetation studies have been conducted
since the 1970s. In our study, we analyzed field-scale methane emissions measured by the eddy
covariance method at Abisko–Stordalen Mire for 3 years (2014–2016). The
site is a subarctic mire mosaic of palsas, thawing palsas, fully thawed
fens, and open water bodies. A bimodal wind pattern prevalent at the site
provides an ideal opportunity to measure mire patches with different
permafrost status with one flux measurement system. The flux footprint for westerly winds was dominated by elevated palsa plateaus, while the footprint was almost equally distributed between palsas and thawing bog-like areas for
easterly winds. As these patches are exposed to the same climatic and
weather conditions, we analyzed the differences in the responses of their
methane emission for environmental parameters. The methane fluxes followed a similar annual cycle over the 3 study
years, with a gentle rise during spring and a decrease during autumn,
without emission bursts at either end of the ice-free season. The peak emission during the ice-free season differed significantly for the two mire areas with different permafrost status: the palsa mire emitted 19 mg-C m−2 d−1 and the thawing wet sector 40 mg-C m−2 d−1. Factors controlling the methane emission were
analyzed using generalized linear models. The main driver for methane fluxes
was peat temperature for both wind sectors. Soil water content above the
water table emerged as an explanatory variable for the 3 years for
western sectors and the year 2016 in the eastern sector. The water table
level showed a significant correlation with methane emission for the year
2016 as well. Gross primary production, however, did not show a significant
correlation with methane emissions. Annual methane emissions were estimated based on four different gap-filing
methods. The different methods generally resulted in very similar annual
emissions. The mean annual emission based on all models was 3.1 ± 0.3 g-C m−2 a−1 for the western sector and 5.5 ± 0.5 g-C m−2 a−1 for the eastern sector. The average annual emissions,
derived from these data and a footprint climatology, were 2.7 ± 0.5 and 8.2 ± 1.5 g-C m−2 a−1 for the
palsa and thawing surfaces, respectively. Winter fluxes were relatively
high, contributing 27 %–45 % to the annual emissions.
Erosion rates in a wet, temperate climate derived from rock luminescence techniques
Authors: Smedley Rachel K. , Small David , Jones Richard S. , Brough Stephen , Bradley Jennifer , Jenkins Geraint T. H.
Published: October 2021

Abstract. A new luminescence erosion meter has huge potential for inferring erosion
rates on sub-millennial scales for both steady and transient states of
erosion, which is not currently possible with any existing techniques
capable of measuring erosion. This study applies new rock luminescence
techniques to a well-constrained scenario provided by the Beinn Alligin rock
avalanche, NW Scotland. Boulders in this deposit are lithologically
consistent and have known cosmogenic nuclide ages and independently derived
Holocene erosion rates. We find that luminescence-derived exposure ages for
the Beinn Alligin rock avalanche were an order of magnitude younger than
existing cosmogenic nuclide exposure ages, suggestive of high erosion rates
(as supported by field evidence of quartz grain protrusions on the rock
surfaces). Erosion rates determined by luminescence were consistent with
independently derived rates measured from boulder edge roundness. Inversion
modelling indicates a transient state of erosion reflecting the stochastic
nature of erosional processes over the last ∼4.5 kyr in the
wet, temperate climate of NW Scotland. Erosion was likely modulated by known fluctuations in moisture availability and to a lesser extent temperature, which controlled the extent of chemical weathering of these highly lithified rocks prior to erosion. The use of a multi-elevated temperature, post-infra-red, infra-red stimulated luminescence (MET-pIRIR) protocol (50, 150 and 225 ∘C) was advantageous as it identified samples with complexities that would not have been observed using only the standard infra-red stimulated luminescence (IRSL) signal measured at 50 ∘C, such as that introduced by
within-sample variability (e.g. surficial coatings). This study demonstrates that the luminescence erosion meter can infer accurate erosion rates on sub-millennial scales and identify transient states of erosion (i.e. stochastic processes) in agreement with independently derived erosion rates for the same deposit.
Brief communication: Effective earthquake early warning systems: appropriate messaging and public awareness roles
Authors: Zhang Meng , Qiao Xue , Seyler Barnabas C. , Di Baofeng , Wang Yuan , Tang Ya
Published: October 2021

Abstract. The earthquake early warning systems (EEWSs) in China
have achieved great progress, with warning alerts being successfully
delivered to the public in some regions. We examined the performance of the
EEWS in China's Sichuan Province during the 2019 Changning earthquake.
Although its technical effectiveness was tested with the first alert
released 10 s after the earthquake, we found that a big gap existed between
the EEWS's message and the public's response. We highlight the importance of
EEWS alert effectiveness and public participation for long-term resiliency,
such as delivering useful alert messages through appropriate communication
channels and training people to understand and properly respond.

Desigualdad de género y agencia femenina en el sector público externalizado
Authors: Bermúdez Figueroa Eva , Roca Beltrán
Published: October 2021

Pese a los avances en materia de igualdad de género en la administración pública, la información disponible sobre la situación en aquellos sectores externalizados es insuficiente. A través de la mirada crítica de género a la visión managerialista y privatizadora de la Nueva Gestión Pública, este artículo pretende estudiar las relaciones de género y laborales en las empresas auxiliares de la administración municipal. A partir del estudio de caso de un municipio de la provincia de Cádiz, y empleando una metodología mixta, se analizan las principales desigualdades laborales entre hombres y mujeres en los servicios externalizados del ayuntamiento, así como las experiencias, percepciones y agencia de las mujeres. El estudio desvela la existencia de importantes desigualdades laborales por razón de género, que se manifiesta la segregación horizontal y vertical, pero también en diferencias salariales. El análisis cualitativo permite conocer los mecanismos informales detrás de estas dinámicas, asociadas a la desvalorización del trabajo femenino o las dificultades para la conciliación. Asimismo, se reconoce la agencia femenina ante esta doble situación de opresión (de clase y de género), que se manifiesta no sólo en la actividad sindical en sectores feminizados, sino también en casos de auto-organización de las mujeres en el interior de las estructuras sindicales.
¿Hacia el fin del rol protector del Estado en el sur de Europa? El impacto de la Gran Recesión sobre las instituciones laborales
Authors: Sánchez-Mosquera Marcial
Published: October 2021

En este artículo analizo el impacto de las profundas reformas institucionales acometidas durante la Gran Recesión en el rol protector del Estado en el sur de Europa. El modelo de relaciones laborales del sur de Europa sufrió una verdadera crisis normativa debido a la condicionalidad económica de la Troika entre 2010 y 2014. Pero no puede afirmarse que el Estado haya quedado desprovisto de recursos protectores, ni que el impacto haya sido homogéneo ni irreversible. Causas internas y externas explican una pluralidad considerable de resultados. Las instituciones italianas apenas se han alterado e incluso ampliaron la aseguración de los desempleados. En España, la limitación ha sido moderada. En Portugal fue más intensa, pero desde 2015 se ha revisado esa afectación y el salario mínimo nacional ha frenado la desprotección. En Grecia, en cambio, sí se ha producido una desprotección radical y difícil de revertir.
