A Novel Approach Using Adaptive Neuro Fuzzy Based Droop Control Standalone Microgrid In Presences of Multiple Sources
Authors: Singirikonda Srinivas , Obulesu Y.P.
Published: February 2020

In this paper, a novel Q/P droop control strategy for regulating the voltage and frequency in Standalone micro grid with multiple renewable sources like solar and wind is presented. The frequency and voltage control strategy is applied to a Standalone micro grid with high penetration of intermittent renewable generation system. Adaptive Neuro-Fuzzy logic Interface system (ANFIS) controller is used for frequency and voltage control for Renewable generation system. Battery energy storage system (BESS) is used to generate nominal system frequency instead of using the synchronous generator for frequency control strategy. A synchronous generator is used to maintain the state of charge (SOC) of the BESS, but it has limited capacity. For Voltage control strategy, we proposed reactive power/active power (Q/P) droop control to the conventional reactive power controller which provides voltage damping effect. The induced voltage fluctuations are reduced to get nominal output power. The proposed model is tested on different cases and results show that the proposed method is capable of compensating voltage and frequency variations occurring in the micro grid with minimal rated synchronous generator. ©2020.

Tax Incentive Policy for Geothermal Development: A Comparative Analysis in ASEAN
Authors: Abidin Mohammad Zainul , Rosdiana Haula , Salomo Roy Valiant
Published: February 2020

This paper examines tax incentive policies in geothermal industries in ASEAN to better understand the development of geothermal industry investment in the ASEAN Member States (AMS) using a qualitative method. The results indicate that tax incentive policies have supported the investment climate and the development of geothermal industries in the AMS. Geothermal investments and production capacities in AMS have increased significantly. AMS that provide geothermal tax incentives include Indonesia, Lao PDR, the Philippines, Thailand and Vietnam. The performance of geothermal tax incentive policies is reflected in the level of utilization of geothermal potential, which is higher in states that provide greater tax incentives. The results also indicate that geothermal power plants in AMS use dry steam, flash and binary cycle technologies with flash plants being the most common. Results suggest that the future development of geothermal energy in AMS will be related to the tax incentive policy and investment climate in those states. Furthermore, the granting of various types of tax incentives should be focused on the initial investment in geothermal development. ©2020. CBIORE-IJRED. All rights reserved

Published: February 2020

In Algeria and Turkey, the sheep production systems are based on the under extensive rural conditions and their genetic management has led to increased homozygosity and hence productivity loss. The identification of inter-breed and intra-breed genetic diversity plays a key role in the shaping of conservation and breeding programs. The present study was conducted to investigate the genetic diversity of native sheep breeds reared in Turkey and Algeria. A total of 240 animals from four Algerian (Hamra, Ouled Djellal, Sidaou, and Tazegzawt) and four Turkish (White Karaman, South Karaman, Karacabey Merino, and Kıvırcık) native sheep breeds were genotyped with fourteen microsatellite markers recommended by FAO. A total of 340 alleles were detected from fourteen markers studied. All the eight breeds exhibited moderate to high levels of genetic diversity, with a slight superiority of the Algerian sheep breeds. Overall FIS value was low, but highly significant (p < 0.001). It may have been due to the high inbreeding within the population. The mean global coefficient of gene differentiation (GST) showed that approximately 94.0 % of the genetic variation was within-population. The highest number of private alleles with a frequency above 5 % was observed in Ouled Djellal sheep. Structure analysis of populations studied revealed the most appropriate K with four genetic clusters. As the result, the dendrogram showed that the Algerian sheep breeds were completely separated from the Turkish sheep breeds furthermore the Bayesian clustering revealed a high level of admixture, especially in Algerian sheep populations.
Higher yielding varieties of common buckwheat (Fagopyrum esculentum Moench) with determinate growth habit (single mutation det) manifest higher photosynthesis rate at stage of grain filling

Published: February 2020

Comparison of common buckwheat varieties with determinate vs. indeterminate growth habit reveals no differences in leaf photosynthesis rate at stage before flowering. However, at stage of seed filling the difference was significant. Maximal difference was 20 days after early flowering, i.e in period of most intensive seed formation. These results show that determinate varieties have higher sink strength providing by developing seeds. It is correlated with higher yield ability of such varieties. Probably, growth limitation resulting from det-mutation leads to some shifts in system of sink priorities of buckwheat plant and allows initiate the development of additional seeds. One more possible cause of alteration of the physiological parameters in determinate varieties is some optimization of plant structure: in terms of physiology the determinate buckwheat is a plant which is more similar to cereals than indeterminate buckwheat. However, underlying physiological changes accompanying the transition from indeterminate toward determinate growth in buckwheat remain almost unknown. Assumption about strong effect of det-mutation per se on photosynthesis rate was not supported in our work. Alternative assumption about accumulation of additional genes enhancing the sink ability suggests opportunities for additional progress in the selection work using tools evaluating photosynthesis intensity at stage of grain filling.

Published: February 2020

This study was carried out on grain yield in wheat genotypes with the aim of assessing genetic potential of drought tolerance. The experiment was performed as split plot in the form of randomized complete block design with three replications under normal and drought stress conditions with 32 genotypes. Based on grain yield, and under the condition of non-stress and drought stress, 5 drought tolerance indices are estimated including Tolerance Index (TOL), Stress Tolerance (STI), Mean Productivity (MP), Geometric Mean (GMP) and, Harmonic Mean (HM) for all kinds of genotypes. The analysis of yield correlation and drought tolerance indices in two environments indicated that STI, MP, GMP, HM indices were the most suitable parameters for screening wheat genotypes. Principal components analysis exhibited that the 83 % of first principal component and the 15 % of second one justified the variation of the initial data. Drawing bi-plot diagram declared that Sabalan, Shabrang, Aria, Azar, Azadi, and T2 genotypes were highly functional and resistant to drought stress.
Modified CTAB protocol for RNA extraction from Lemon balm (Melissa officinalis L.)
Authors: RAHMANI Fatemeh , AMRAEE Leila
Published: February 2020

Ribonucleic acid (RNA) quality and integrity are crucial for many studies in plant molecular biology. High-quality RNA extraction from plants with high levels of compounds such as polysaccharides, polyphenols, and other secondary metabolites are problematic. RNA extraction from Lemon balm tissues can be difficult due to the presence of polyphenolic and polysaccharide compounds or can be done by expensive protocols. This study shows improvement of a CTAB-based protocol which allows rapid and easy isolation of high-quality RNA from Lemon balm plant. The RNA obtained is suitable for cDNA synthesis and RT-PCR experiments.

Published: February 2020

The continuous trend of global warming and increasing interest toward cultivating sugar beet (Beta vulgaris L. ssp. vulgaris var. altissima Döll) in tropical regions led us to conduct this study to investigate the effect of high temperature on sugar beet at initial growth stages. Thirty one genotypes were incubated at two temperatures (20 °C and 30 °C) in laboratory for germination test. The same genotypes were assessed for physiological parameters at 30 °C in greenhouse, too. Increasing temperature decreased germination indices with a high variability among the genotypes. Seed vigor index and seminal root length were decreased higher than other indices. The genotypes with higher greenness index had higher total dry mass, leaf area and leaf temperature depression (LTD), and those with higher seed vigor index indicated great quantum efficiency of PSII (Fv/Fm) values. ‘S1-92521’ produced high records in both laboratory and greenhouse experiments. Although ‘S1-92521’ showed good tolerance in both laboratory and greenhouse experiments, totally, sugar beet genotypes had different performance at two experiments. According to the results, seed vigor index could be used as a screening tool in laboratory, and LTD and Fv/Fm were considered as good criteria for screening heat-tolerant genotypes in greenhouse.
Implementation of metrological traceability in laboratory medicine: where we are and what is missing
Authors: Panteghini Mauro , Braga Federica
Published: February 2020

Background

The Joint Committee on Traceability in Laboratory Medicine (JCTLM) has recently created the Task Force on Reference Measurement System Implementation (TF-RMSI) for providing guidance on traceability implementation to in vitro diagnostics (IVD) manufacturers. Using serum creatinine (sCr) as an example, a preliminary exercise was carried out by checking what type of information is available in the JCTLM database and comparing this against derived analytical performance specifications (APS) for measurement uncertainty (MU) of sCr.

Content

APS for standard MU of sCr measurements were established as a fraction (≤0.75, minimum quality; ≤0.50, desirable quality; and ≤0.25, optimum quality) of the intra-individual biological variation of the measurand (4.4%). By allowing no more than one third of the total MU budget for patient samples to be derived from higher-order references, two out of the four JCTLM reference materials (RMs) at least allow minimum APS to be achieved for the MU of patient samples. Commutability was explicitly assessed for one of the JCTLM-listed matrixed RMs, which was produced in compliance with ISO 15194:2009 standard, whereas the remaining three RMs were assessed against the ISO 15194:2002 version of the standard, which only required the extent of commutability testing to be reported. Regarding the three listed reference methods, the MU associated with isotopic dilution-mass spectrometry coupled to gas chromatography (ID/GC/MS) and isotopic dilution-mass spectrometry coupled to liquid chromatography (ID/LC/MS) would allow APS to be fulfilled, while the isotope dilution surface-enhanced Raman scattering (ID/SERS) method displays higher MU.

The most recently listed RM for sCr in the JCTLM database meets the ISO 15194:2009 requirements with MU that would allow APS to be fulfilled and has had commutability demonstrated for use as a common calibrator in implementing traceability of sCr measurements. Splitting clinical samples with a laboratory performing ID/GC/MS or ID/LC/MS provides an alternative but would also require all components of uncertainty of these materials to be assessed.

Outlook

Using appropriately derived APS to judge whether reference measurement system components are fit for purpose represents a novel approach. The TF-RMSI is planning to review a greater number of measurands to provide more robust information about the state of the art of available reference measurement systems and their impact on the ability of clinical measurements to meet APS.
English similarity predicates construe particular dimensions of similarity
Authors: Fishman Alon
Published: February 2020

This paper investigates the ways English speakers employ the predicateslike,similar, andresembleto express similarity in natural speech. A corpus of 450 instances was created and manually coded, and an acceptability rating experiment was conducted. Converging evidence from the corpus analysis and the experiment shows that the three predicates occur with the same range of uses, but differ in their propensities to occur with particular dimensions of similarity. Specifically,likeis associated with metaphorical comparisons, andresembleis associated with visual comparisons. A synchronic account of these findings is developed, based on a distinction between conventionally encoded meaning and prototypical usage. A diachronic account is also proposed, highlighting the commonality in the predicates’ conceptual origins and the differences in their historical usage. This work has theoretical and methodological implications for the study of similarity. In particular, it raises the possibility that previous findings may be distorted due to a reliance on certain similarity predicates in the phrasing of experimental instructions and stimuli. It also ties into debates on synonymy, suggesting a shift in attention from a distinction between denotational and associative meaning, to the aforementioned distinction between conventional and prototypical meaning.
On the Surface Diffusion Flow with Triple Junctions in Higher Space Dimensions
Authors: Garcke H. , Gößwein M.
Published: February 2020

We show short time existence for the evolution of triple junction clusters driven by the surface diffusion flow. On the triple line we use the boundary conditions derived by Garcke and Novick-Cohen as the singular limit of a Cahn-Hilliard equation with degenerated mobility. These conditions are concurrency of the triple junction, angle conditions between the hypersurfaces, continuity of the chemical potentials and a flux-balance. For the existence analysis we first write the geometric problem over a fixed reference surface and then use for the resulting analytic problem an approach in a parabolic Hölder setting.

Authors: Hampannavar Santoshkumar , Chavhan Suresh , Mansani Swapna , Yaragatti Udaykumar R.
Published: February 2020

In this paper mathematical model for traffic pattern analysis, prediction and resource utilization of Electric Vehicles (EV) in aggregator regions/parking lot zones is proposed. The proposed and presented mathematical model for EV traffic pattern/resource utilization in smart city can be used to estimate the amount of power/voltage available/required by EVs in different aggregator regions. Development of multiagent communication (MAC) based framework for aggregator to EV communication is discussed. V2G aggregation in distribution network forms a Physical part and utility side with sensing/communication forms a Cyber part which combinedly constitutes a Cyber-Physical system. Simulations were carried out on IEEE 33/69 bus test systems using MATLAB and MOBILE C was used for MAC. The results obtained were promising in terms of improved voltage profile and reduced power losses.
Two different missense mutations of PEX genes in two similar patients with severe Zellweger syndrome: an argument on the genotype-phenotype correlation
Authors: Havali Cengiz , Dorum Sevil , Akbaş Yılmaz , Görükmez Orhan , Hirfanoglu Tugba
Published: February 2020

Background

Peroxisomal biogenesis disorders (PBDs) include a miscellaneous group of diseases which cause serious multisystem disease. Mutations of 13 different PEX genes lead to PBDs including Zellweger syndrome (ZS). Different types of mutations of PEX1 and PEX10 genes are correlated with broad-range phenotypes of PBDs.

Case presentation

Patient 1 is a 4-month-old boy who was affected by myoclonic seizures, poor oral feeding since birth. The patient was hypotonic and had hepatosplenomegaly. Patient 2 is a 2-month-old boy who presented with decreased movement, severe hypotonia and failure to thrive. The laboratory studies of the patients revealed increased plasma very-long-chain fatty acids (VLCFAs). The genetic analyses of patient 1 demonstrated the first homozygous missense mutation in the PEX10 gene. A novel homozygous missense mutation was found in the PEX1 gene in patient 2.

Conclusions

This report highlights that the detected homozygous missense mutations of PEX10 and PEX1 genes and the substitutions of specific amino acids lead to the severe form of PBDs.
The role of LCPUFA-ω3 on the obesity-associated hyperandrogenemia of pubertal girls: secondary analysis of a randomized clinical trial
Authors: López-Alarcón Mardia Guadalupe , Vital-Reyes Víctor Saúl , Hernández-Hernández Francisco Iván , Maldonado-Hernández Jorge
Published: February 2020

Introduction

Hyperandrogenism (HA), either clinical or biochemical, is associated with obesity in adolescent girls. Long chain polyunsaturated fatty acids ω3 (LCPUFA-ω3) play protective roles in some obesity-associated morbidities, but their contribution to preventing HA is unclear. Our aim was to examine the potential positive relationships between erythrocyte LCPUFA-ω3, with or without supplementation, and hyperandrogenemia.

Methods

Secondary analysis of a clinical trial that was conducted previously to analyze the effect of LCPUFA-ω3 on insulin resistance and body weight. Here, we present a cross-sectional analysis of 180 girls with obesity, and a longitudinal analysis of 117 girls who completed a 3-month supplementation period (57 LCPUFA-ω3 [DO3] and 60 placebo [DP)]). Dehydroepiandrosterone sulfate (DHEAS), total testosterone (TT) and steroid hormone binding globulin (SHBG) were measured with chemiluminescence; free testosterone (FT) was calculated. Erythrocyte fatty acids were determined by gas chromatography. Non-parametric statistics was used for analysis.

Results

In cross-sectional analysis, age (odds ratio [OR] = 1.35; 95% confidence interval [CI] = 1.03, 1.78; p = 0.027), insulin (OR = 1.05; 95% CI: 1.00, 1.10; p = 0.018), and erythrocytes eicosapentaenoic acid (EPA) (OR = 0.04; 95% CI: 0.01, 0.65; p = 0.012) were predictors of hyperandrogenemia (FT >0.63 ng/mL). In longitudinal analysis, EPA, adiponectin and SHBG increased, while FT decreased, in the DO3 group (p < 0.05). The risk of hyperandrogenemia at the end of follow-up was predicted by basal hyperandrogenemia (OR = 18.16, 95% CI: 5.37, 61.4; p < 0.001) and by increases in EPA (OR = 0.40; 95% CI: 0.01, 0.65; p = 0.06 marginal significance).

Conclusions

Our results suggest a preventive role of EPA on the risk for hyperandrogenemia in girls with obesity, but further studies are needed to demonstrate a benefit.
The effect of celiac disease and gluten-free diet on pubertal development: a two-center study
Authors: Bayrak Nevzat Aykut , Volkan Burcu , Haliloglu Belma , Kara Soner Sertan , Cayir Atilla
Published: February 2020

Objectives

We aimed to assess whether age at menarche and pubertal development (Tanner stage) are related to gluten-free diet (GFD) adherence, hormonal status, micro-nutrient levels and body mass index (BMI) in children with celiac disease (CD).

Methods

In this two-center, cross-sectional study, CD patients and healthy individuals were studied. CD patients were re-evaluated after 1 year of follow-up. Height, weight, Tanner stage, age at menarche and diet compliance were recorded. Blood samples for anti-tissue transglutaminase IgA (TTG), pituitary gonadotropins, gonadal hormones, prolactin and micronutrients (folate, vitamin B12, vitamin D, ferritin, iron and, iron-binding capacity [IBC]) were assayed.

Results

Consecutive age- and sex-matched 228 celiac patients (12.92 ± 2.35 years; 67.9% female) and 135 non-celiac healthy individuals (12.77 ± 2.25 years; 65.2% female) were studied. Tanner stage was significantly higher in the control group for both girls and boys (p < 0.05). The mean age at menarche was significantly lower in healthy individuals (13.13 ± 1.01 vs. 12.15 ± 0.97, p < 0.001). By multivariate analysis, GFD adherence, transferrin saturation (sTrf), total IBC (TIBC) and vitamin D status were found to be positively correlated with Tanner stage (p < 0.05). After 1 year, 192 of the CD patients were re-evaluated. GFD compliance was better (TTG levels: 135.59 ± 73.88 vs. 71.53 ± 69.40, p < 0.001) and it was correlated with Tanner stage (r = 0.49, p < 0.01), sTrf (r = 0.66, p < 0.01) and IBC (r = 0.23, p < 0.05).

Conclusions

Our data show that adequate weight gain, adherence to GFD, sufficient iron and vitamin D status are essential factors for salubrious puberty in CD patients.

Introduction

According to the current classification of the Lawson Wilkins Pediatric Endocrine Society (LWPES) and the European Society for Pediatric Endocrinology (ESPE) of Disorders of Sex Development (DSD), etiologies vary around the world. Ethnic or genetic diversity probably explains this variability. We therefore conducted the present study on etiologies of DSDs in a country from central Africa.

Methods

We carried out an observational retrospective study at the Pediatric Endocrinology Unit of the Mother and Child Centre of the Chantal Biya Foundation in Yaounde, Cameroon from May 2013 to December 2019. All patients diagnosed with a DSD were included, and incomplete files excluded.

Results

We included 80 patients diagnosed with DSD during the study period. The 46,XX DSD were the most frequent in our study population (n = 41, 51.25%), with congenital adrenal hyperplasia (CAH) as the main diagnosis. The 46,XY DSD accounted for 33.75% and sex chromosome DSD group represented 15% of the study population.

Conclusions

DSDs are not an exceptional diagnosis in a Sub-Saharan context. 46,XX DSD are the most prevalent diagnosis in our setting. The diagnosis of all these affections is late compared to other centers, justifying advocacy for neonatal screening of DSDs in our context.

Published: February 2020

Background

This study aimed to investigate the presence of sleep disturbances in children with Prader-Willi syndrome (PWS) using the Sleep Disturbance Scale for Children (SDSC).

Methods

The SDSC, which was designed to identify the presence and severity of different sleep disorders, was applied to 50 patients with PWS and 112 controls.

Results

Patients with PWS achieved worse scores in the sleep-disordered breathing and disorders in initiating and maintaining sleep in the SDSC questionnaire as compared with controls. We also observed that patients with PWS were more prone to having hyperhidrosis. We did not observe significant differences in the presence of other types of sleep disorders (such as hypersomnolence) between the PWS and control groups.

Conclusions

The results obtained with the SDSC questionnaire showed that children with PWS have more sleep breathing disorders and disorders in initiating and maintaining sleep as compared to controls. Additionally, we demonstrated that patients with PWS associates significantly with the presence of hyperhidrosis during sleep. However, SDSC was not reliable to identify the excessive daytime somnolence in patients with PWS, as previously reported in the literature.
The Evolution of Social Contracts
Authors: Vlerick Michael
Published: February 2020

Influential thinkers such as Young, Sugden, Binmore, and Skyrms have developed game-theoretic accounts of the emergence, persistence and evolution of social contracts. Social contracts are sets of commonly understood rules that govern cooperative social interaction within societies. These naturalistic accounts provide us with valuable and important insights into the foundations of human societies. However, current naturalistic theories focus mainly on how social contracts solve coordination problems in which the interests of the individual participants are (relatively) aligned, not competition problems in which individual interests compete with group interests (and in which there are no group beneficial Nash equilibrium available). In response, I set out to build on those theories and provide a (more) comprehensive naturalistic account of the emergence, persistence and evolution of social contracts. My central claim is that social contracts have culturally evolved to solve cooperation problems, which include both coordination and competition problems. I argue that solutions to coordination problems (which I spell out) emerge from “within-group” dynamics, while solutions to competition problems (which I also spell out) result largely from “between-group” dynamics.

This paper examines how black members of Congress (MCs) have recognized police brutality as an issue on the congressional agenda from 1973 to 2016. Using a dataset of every bill introduced by black members of Congress during the period of study, I show that, in general, police brutality has not been an important component of black MCs’ legislative portfolios. Instead, it is an occasional focus of bill sponsorship in response to discrete, highly salient incidents of brutality and murder. These findings are contextualized through a broader discussion of black representation as a tactic for black liberation and the similarities between the history of anti-lynching legislation and the contemporary fight against police brutality.

This article sets out a summary of standards for departmental accreditation set by the British Society of Echocardiography (BSE) Departmental Accreditation Committee. Full accreditation standards are available at www.bsecho.org. The BSE were the first national organisation to establish a quality standards framework for departments that support the practice of individual echocardiographers. This is an updated version which recognises that, not only should all echocardiographers be individually accredited as competent to practice, but that departments also need to be well organised and have the facilities, equipment and processes to ensure the services they deliver are of an appropriate clinical standard. In combination with individual accreditation, departmental accreditation lays down standards to help ensure safe and effective patient care. These standards supersede the 2012 BSE Departmental Accreditation Standards. Standards are set to cover all potential areas of practice, including transthoracic (level 2) echocardiography, transoesophageal echocardiography, stress echocardiography, training, and emergency (level 1) echocardiography. The emergency echocardiography standard is a new addition to departmental accreditation and has been developed with input from the Intensive Care Society.
A política de cohesión europea. Evolución e perspectivas

Published: February 2020

A evolución do que foi o mercado común ata chegar á Unión Europea pode estudarse desde diferentes puntos de vista. Neste traballo tomáronse a integración económica e, sobre todo, a cohesión económica, social e territorial como claves para interpretar un proceso que, malia a crise que atravesa actualmente, chamou a atención de políticos, profesionais e de estudosos. Distín-guense catro etapas: a primeira, desde as súas orixes ata a Acta Única Europea (AUE, 1987); a se-gunda, desde a AUE ata o Tratado de Ámsterdam (TA, 1999); a terceira, desde o TA ata a grande ampliación (2004-2007); e a cuarta, na que nos atopamos, é unha zona aberta. Mantense a tese de que, despois da gran galopada que representou a AUE e a presidencia de Delors, a unificación de Alemaña e a desaparición da URSS marcan un punto de inflexión á baixa, cuxa plasmación docu-mental e financeira é a Axenda 2000. A integración económica é obxecto de varios intentos de re-lanzamento (Estratexia de Lisboa, Estratexia Europa 2020, Acta do Mercado Único), sen lograr atar os cabos soltos. En materia de cohesión, desde a reforma dos fondos estruturais, nunca como ago-ra, que é cando máis se necesita, foi tan débil o apoio financeiro e económico real para fortalecer a cohesión. Só na literatura oficial está en alza. Son uns puntos de vista non exentos de polémica. Con todo, e a pesar da crise, da falta de liderado e do exceso de prepotencia, paga a pena continuar no empeño de seguir avanzando cara á unión política

Published: February 2020

A serie de normas EN 9100 constitúe unha adaptación das normas ISO 9000 ás especificidades do sector aeroespacial, para asegurar que todos os produtos relativos a este sector son seguros e competitivos. Os obxectivos deste traballo son, por un lado, analizar os resultados derivados da adhesión á normativa EN 9100 por parte das empresas do sector aeroespacial español e, por outro, verificar se eses resultados están influenciados polo tamaño desas empresas. Para iso envióuselles un cuestionario aos directores de calidade das 355 empresas que configuran este sector. Das respostas recollidas nos 115 cuestionarios recibidos, conclúese que a implantación da normativa EN 9100 ten unha influencia positiva na maioría das empresas participantes para a obtención de beneficios tanto de índole “interna” coma “externa”, sendo estes últimos os que presentan unha maior intensidade. Así mesmo, verifícase que o tamaño das empresas non provoca diferenzas significativas polo que se refire a esa influencia positiva, aínda que no tocante ás empresas “pequenas” os beneficios de tipo interno parecen obterse con maior dificultade.
Políticas europeas de auditoría en tempos de crise
Authors: García Benau María Antonia , Zorio Grima Ana , Novejarque Cibera Josefina
Published: February 2020

A Unión Europea respondeu á crise financeira internacional tomando medidas que permitan recuperar a estabilidade nos mercados e favorecer o crecemento económico nos Estados membros. No terreo da auditoría, no ano 2010 publicouse o documento «Libro Verde. Política de auditoría: lecciones de la crisis», que mostra a intención da Comisión Europea de asumir o liderado en materia de auditoría no ámbito internacional, promovendo a cooperación internacional no marco do Consello de Estabilidade Financeira e do G-20. A este documento séguenlle a Resolución do Parlamento Europeo, de 13 de setembro de 2011, sobre «Políticas de auditoría: lecciones de la crisis»; a Proposta de directiva do Parlamento Europeo e do Consello pola que se modifica a Directiva 2006/43/CE; e a Proposta de regulamento do Parlamento Europeo e do Consello sobre as auditorías das entidades de interese público. Este traballo trata sobre a visibilidade que a Comisión Europea lle deu ao traballo dos auditores nos momentos económicos tan difíciles que estamos vivindo. O noso obxectivo é debater sobre o modelo normativo da auditoría instaurado en Europa e sobre a forma na que se están emitindo políticas europeas en materia de auditoría para facerlle fronte á crise financeira internacional iniciada no ano 2008. Este artigo demostra que a regulación europea está formulada para exercer un maior control sobre o exercicio da actividade da auditoría. Os avances desas propostas son indiscutibles, pero este traballo reflexiona sobre se tanta regulación ten un efecto claro sobre a calidade da auditoría.
Unha visión rexional da pobreza en España no marco da crise económica actual

Published: February 2020

Este artigo pretende achegar unha visión rexional da pobreza en España desde a perspectiva da Estratexia Europa 2020 facendo fincapé nos cambios derivados da crise económica. Esta análise realízase tomando como marco o obxectivo de crecemento inclusivo que fixa a Estratexia Europea 2020 (EU2020S), adoptada formalmente pola Unión Europea no ano 2010, para reducir os niveis de pobreza e exclusión social. O estudo de trece indicadores socioeconómicos a nivel de comunidades autónomas (CC.AA.) e a identificación de relacións entre os indicadores socioeconómicos da Estratexia 2020 permitiu: i) situar España e as súas comunidades autónomas no contexto europeo, ii) poñer en evidencia cambios no contexto social derivados da actual crise económica, iii) identificar relacións entre as variables estudadas, e iv) propoñer clústeres de rexións segundo a súa distancia aos obxectivos da Estratexia 2020.
Mercado de traballo, formación e exclusión social: análise da situación da poboación reclusa de Galicia
Authors: Barreiro Gen María , Novo Corti Isabel , Ramil Díaz María
Published: February 2020

Aínda que a exclusión social pode proceder dunha única causa, existen colectivos cunha maior probabilidade de padecela porque se atopan en varias destas circunstancias á vez. A inclusión no mercado laboral é unha peza fundamental para evitala, xa que o desemprego pode conducir ao illamento e á pobreza. Cando esta situación se combina coa carencia dunha formación adecuada, que dificulta a consecución dun traballo, a saída da espiral que conduce á exclusión resulta máis complexa. Para a poboación reclusa, ademais da condena pola comisión dun acto delituoso, é frecuente atopar varios motivos que poden xerar exclusión, xeralmente vinculados ao delito cometido. Neste traballo analízase a situación das persoas que cumpren condena nos centros penitenciarios e de inserción social de Galicia (España) mediante unha análise cuantitativa centrada nas posibilidades de inclusión posterior da poboación reclusa a través das actitudes e aptitudes mostradas cara a algunhas cuestións clave. Esa actitude relaciónase co nivel de estudos e coa formación do individuo, así como coas redes sociais coas que conta ou coa súa propia consciencia da situación que está vivindo.
Termas de Portugal, grado de madurez de la calidad percibida por los gestores. Estudio empírico
Authors: Álvarez García José , Fraiz Brea José Antonio , Del Río Rama María de la Cruz
Published: February 2020

Neste artigo expóñense os resultados do estudo cuxo obxectivo é identificar as motivacións que impulsarían ás termas de Portugal a implantar e certificar un Sistema de Xestión de Calidade (SXC), coñe-cer os beneficios que perciben que obterían desa implantación, así como analizar o grao de madureza na xestión da calidade destas na actualidade. A metodoloxía de traballo consiste nunha análise descritiva xunto cunha análise factorial que nos permitirán validar as escalas de medida. A poboación obxectivo son as termas de Portugal, pertencentes á Asociación Termas de Portugal (ATP), cunha poboación obxecto de estudo de 32 termas activas. Os resultados obtidos indican que as motivacións máis importantes que im-pulsarían ás termas a implantar un SXC son de índole interna (mellorar os procesos e os procedementos in-ternos, o control e a eficiencia da empresa e servir de base para a Xestión da Calidade Total). Os principais beneficios que esperan obter son ofertar servizos de máis calidade, mellorar as vendas e incrementar a conciencia de calidade dos empregados. Nos factores críticos analizados, as termas de Portugal presentan un nivel de implantación ou un grao de madureza superior ao 70%.
Sistemas de control de xestión, capacidade innovadora e certificacións ISO:

Published: February 2020

Seguindo o marco conceptual presentado por Simons (1995), o obxectivo principal deste traballo é proporcionarlle unha nova contribución á literatura de contabilidade de xestión examinando a relación entre os sistemas de control de xestión (SCX), a certificación en ISO e o rendemento da capacidade innova-dora (RCI), así como o seu impacto no rendemento organizacional. A mostra componse de 231 empresas españolas pertencentes ao sector agroalimentario. A información obtense a través de enquisas aos xeren-tes destas organizacións. No estudo incluíronse catro ferramentas pertencentes aos SCX: contabilidade de custos, balanced scorecard, plan de negocios e orzamentos. Os resultados obtidos pola aplicación dun mo-delo de ecuacións estruturais indican que o uso interactivo dos SCX inflúe positivamente no RCI da empre-sa. Ademais, o RCI atópase positiva e significativamente relacionado co rendemento organizacional. Por úl-timo, a certificación en ISO establécese como un potenciador de RCI a través do uso interactivo dos SCX.
Influencia de variables persoais no compromiso organizativo dos empregados do sector hoteleiro
Authors: González Santa Cruz Francisco , Sánchez Cañizares Sandra María , López Guzmán Tomás
Published: February 2020

O compromiso organizativo é un constructo de enorme interese para as empresas, dada a relación existente entre este e os distintos indicadores do funcionamento organizativo, como a pro-dutividade, o nivel de absentismo e rotación, o estrés laboral ou a satisfacción do cliente. Esta impor-tancia vólvese maior, se iso é posible, nunha situación de crise como a actual, onde eses indicadores son claves para o éxito das organizacións en xeral e para as hoteleiras en particular, que se caracte-rizan por un contacto intenso cos clientes. Baixo este prisma, este artigo pretende desenvolver o co-ñecemento sobre o compromiso organizativo dos empregados do sector hoteleiro (concretamente na provincia e na cidade de Córdoba) e a súa relación con determinadas variables persoais destes. Neste sentido, apréciase claramente unha relación lineal e progresiva con respecto á idade dos traballado-res e inversa co seu nivel educativo. Desta forma, preténdese que a través do mellor coñecemento deste constructo, os directivos hoteleiros entendan a importancia do seu desenvolvemento e que o poñan como obxectivo das diferentes áreas de influencia no capital humano.
A evolución das caixas galegas na última década e a súa posterior
Authors: Garrido González María Luz
Published: February 2020

Neste traballo estúdase a evolución das caixas de aforros que operaron en Galicia nos anos previos ao proceso de reestruturación financeira: Caixanova e Caixa Galicia, e analízase a situación á que chegaron estas como consecuencia do seu proceso de fusión e a posterior conversión en banco. Para a investigación, que comprende datos anuais durante o período 2000-2012, escolléronse as va-riables e as ratios adecuadas de acordo coa teoría contable, coa literatura previa e coas memorias das institucións de crédito, para determinar a rendibilidade, solvencia e liquidez destas entidades. Ademais, trátase de evidenciar cales foron os principais causantes que levaron a unha nova integra-ción das caixas fusionadas no grupo NCG Banco mediante axudas do FROB.
Modelos de formación de clústers industriais: revisión das ideas que os
Authors: Bao Cruz Sergio , Blanco Silva Fernando
Published: February 2020

Os clústers son concentracións xeográficas de compañías e institucións dun determinado campo con relacións económicas entre elas. Representan unha nova forma de organización espacial que promove a competencia e a cooperación e supoñen unha forma máis dinámica de achegarse ao estudo do desenvolvemento económico que a tradicional visión por sectores. Diversos estudos pare-cen demostrar unha maior aposta pola innovación nas empresas cando estas se atopan integradas nalgún clúster, así como outras vantaxes de pertencer a estes. Este artigo realiza a revisión teórica das ideas que sustentan o concepto de clúster, onde consideramos importante a falta de concreción do concepto e a existencia dunha ampla colección de definicións, o que supón unha certa ambigüi-dade no uso do termo e que non sempre sexa sinxelo identificalo e marcar unhas fronteiras nítidas que o delimiten.
