Women on Top Management Teams and Firm Performance in German Medium-Sized Enterprises: The Moderating Role of Recruiting Source

Despite substantial research, evidence regarding the relationship between the proportion of women on top management teams (TMTs) and firm performance is still inconclusive. Building on upper echelons theory, this paper expands the discussion of potential moderating effects in this regard by applying a complementary perspective to the commonly studied organization-oriented factors. Applying a person-oriented perspective to the composition of TMTs, this study argues that the recruiting source of TMT members - whether members were recruited from the owner's family, from the internal job market or the external job market - leads to differences in the job-relevant characteristics of TMT members. Consequently, the recruiting source should moderate the relationship between TMT gender composition and performance. Our analysis of 1025 German medium-sized enterprises (MEs) shows that there is no main effect of the proportion of women on firm performance. However, recruiting from the owner's family and the internal labor market have a significant negative moderating influence on the relationship between the proportion of women on TMTs and firm performance. Conversely, hiring externally exerts a significant positive effect.
Novel Isotypic γ/ζ Subunits Reveal Three Coatomer Complexes in Mammals

ABSTRACT In early secretory transport, coat recruitment for the formation of coat protein I (COPI) vesicles involves binding to donor Golgi membranes of the small GTPase ADP-ribosylation factor 1 and subsequent attachment of the cytoplasmic heptameric complex coatomer. Various hypotheses exist as to the precise role of and possible routes taken by COPI vesicles in the mammalian cell. Here we report the ubiquitous expression of two novel isotypes of coatomer subunits γ- and ζ-COP that are incorporated into coatomer, and show that three isotypes exist of the complex defined by the subunit combinations γ1/ζ1, γ1/ζ2, and γ2/ζ1. In a liver cytosol, these forms make up the total coatomer in a ratio of about 2:1:2, respectively. The coatomer isotypes are located differentially within the early secretory pathway, and the γ2/ζ1 isotype is preferentially incorporated into COPI vesicles. A population of COPI vesicles was characterized that almost exclusively contains γ2/ζ1 coatomer. This existence of three structurally different forms of coatomer will need to be considered in future models of COPI-mediated transport.
Sleep-Wake Cycle Expression in Adolescence: Influences of Social Context

Sleep/wake cycle (SWC) characteristics change with development. During adolescence there is a reduction in night sleep duration. A difference between sleep duration on weekdays and at weekends is also observed. Adolescents usually sleep much longer at weekends. A SWC phase delay related to puberal stage is described. In this study, we have investigated SWC patterns among populations living in different environments, either urban (one population) or non-urban (two populations). 423 adolescents studying in the morning period participated in the study. Some characteristics of adolescents’ SWC have been investigated based on a questionnaire previously validated by an actigraphic study. Bedtimes and wake up times were compared by means of ANOVA. Adolescents living in the urban environment showed later bedtimes (p < 0.001) and wake up times (p < 0.001) when compared with adolescents living in rural environments. No differences were found when the rural populations were compared.
Effects of antenatal nutrition counselling on dietary practices and nutritional status of pregnant women: A quasi-experimental hospital based study

Objective: To assess the effects of nutrition education intervention on dietary practices and nutritional status of pregnant women. Methods: In this quasi-experimental study, 215 pregnant women were enrolled from Gynae OPD, Sir Ganga Ram Hospital, Lahore, Pakistan during 2017-18. Dietary practices were assessed using the usual intake form and scoring was done against food guide pyramid. Nutritional status was evaluated by anthropometric measurements and biochemical estimation. In addition to nutrition counselling, each woman was prescribed with supplements commonly used during pregnancy. Dietary habits and nutritional status were reassessed after two months. The women lost to follow up were 21 (9.8%) therefore data obtained from 194 women were subjected to final analysis by using SPSS 20. Results: The age of women ranged between 18 and 38 years. Those who never attended a school were 14.4%; poor 46.0%; and working 3.7%. The comparison between pre- and post-counselling dietary practices showed improvement in the numbers of women taking recommended portions of bread & cereals (79.4% vs. 95.9%, p = <0.001); vegetables (50.5% vs. 64.9%, p = 0.004); milk & dairy products (38.1% vs. 81.4%, p = <0.001); and a reduction in the numbers of women taking recommended portions of meat & bean (100.0% vs. 94.8%, p = 0.002). The frequency of women taking recommended diet as per food guide pyramid improved from 3.1% to 37.1%. Vitamin D status also showed improvement in the numbers of women with normal levels of serum vitamin D (7.1% vs. 33.3%, p = 0.079). Conclusions: Overall, nutrition counseling showed positive effects on nutritional status of pregnant women. Thus, the nutrition counseling must be an essential part of antenatal care for all pregnant women in the setting.
A REVIEW ON THE INTERNAL CONSISTENCY OF A SCALE: THE EMPIRICAL EXAMPLE OF THE INFLUENCE OF HUMAN CAPITAL INVESTMENT ON MALCOM BALDRIDGE QUALITY PRINCIPLES IN TVET INSTITUTIONS

Today’s education institutions are constantly striving to develop and enhance the quality of employees to achieve a competitive advantage in the education market. Investing in developing the human capital quality has become a vital part of the institution strategy in managing the resources. In conjunction with the government aims in enhancing the quality of education system the institution nowadays is striving to nurture the lecturer’s capabilities towards the strategy. This paper aims to assess the internal consistency of data therefore; the further analysis procedure can be carried out systematically. For this purpose, the Cronbach’s alpha coefficient is used in validating the adapted questionnaire. It is a necessary procedure for the pilot testing phase to measure the strength of consistency as it is a well-known and consistent method to measure the reliability of items in the instrument. As for the example of practical, the data derived from a study which was conducted to 345 lecturers from 9 polytechnic campuses in East Coast Malaysia (Kelantan, Terengganu and Pahang) was applied. The questionnaire consists of 63 questions with 7 scales that were used to identify the internal consistency. The preliminary analysis of the reliability analysis resulted in strong associations (greater than 0.6) for all variables. The finding obtained has proven that the research’s instrument has high association of consistency to enhance the quality of the study. Keywords: Human Capital Investment, TVET Institutions, Internal Consistency and Cronbach Alpha
Within-year nest reuse in open-nesting, solitary breeding passerines

During fieldwork at Lake Sic (46°57’N, 23°54’E), Romania, in the summer of 2003, we observed a strange incident of nest reuse in the Great Reed Warbler Acrocephalus arundinaceus . After first laying a complete clutch of five eggs and then ejecting an experimentally added parasite egg together with two of its own eggs, a new clutch was initiated in the same nest. In Tana (70°16’N, 28°19’E), Norway, in June 2003, we observed a similar incident in the Brambling Fringilla montifringilla . In a nest that was completely depredated when 3-4 eggs had been laid, a new clutch was initiated 8-9 days later. This is as far as we know the first time nest reuse has been documented in Great Reed Warblers and Bramblings.
Transfer of sucrose fermenting ability, nisin resistance and nisin production into Streptococcus lactis 712

A gene block controlling sucrose-fermenting ability, nisin resistance and nisin production was found to be transmissible by a conjugation-like process. The ‘pSN’ (sucrose nisin) plasmid was transferred from 8 different nisin-producing donor strains into MG1614, a plasmid-free derivative of Streptococcus lactis 712. In the new host low yields of a plasmid of approx. 30 MDa were isolated but its authenticity as a pSN plasmid has not yet been established. Possibilities for increased nisin yield by genetic manipulation in S. lactis 712 must exist.
A case report of a coronary myocardial bridge with impaired full-cycle ratio during dobutamine challenge

Abstract Background A myocardial bridge (MB) is a coronary variant in which an epicardial coronary artery tunnels through the myocardial band. Although MBs have been reported to cause ischaemia, physiological assessment of an MB has not been fully established. Case summary We encountered a case with exertional chest pain who underwent coronary angiography showing an MB at the mid-left anterior descending artery with systolic compression. Optical coherence tomography showed an MB defined as a homogeneous intermediate intensity surrounding the epicardial artery. The full-cycle ratio, defined as the lowest ratio of distal coronary pressure (Pd) to aortic pressure (Pa) during the entire cardiac cycle, measured 0.89 at rest and 0.73 with intravenous dobutamine of 20 µg/kg/min with a distinctive waveform pattern (early diastolic Pd drop) during a dobutamine challenge. Metoprolol succinate dosage was increased. The patient has been free from chest pain for 7 months after the discharge. Discussion Optical coherence tomography may contribute to anatomical detections of MBs. Because a systolic compression of the MB and release of the vascular lumen during early diastole leads to an early steep pressure loss, early diastolic Pd drop should be one of the specific haemodynamic characteristics of MBs. On the other hand, in a severe atherosclerotic stenosis, Pd drop is typically observed in late diastole, which could be differentiated from that of MBs. Because full-cycle ratio reflects the whole cardiac cycle including early diastole, this might be more useful than other physiological indices for detection of MB-related ischaemia induced by a dobutamine challenge.
Extending cultural mismatch theory: in consideration of race/ethnicity

ABSTRACT Cultural Mismatch Theory (CMT) has emerged as a paradigm to account for the disparate experiences and outcomes of first-generation students (FGSs). Past research on CMT demonstrate how social class disposition can shape cultural mismatch among FGSs; however, the sole focus on social class sacrifices attention to other social markers of significance. Our manuscript explores if FGSs at the intersection of marginalized social class and racial/ethnic identities (working-class, Cambodian American students), experience cultural mismatch and how an institutional mechanism (student organizations) addresses that mismatch. We find that through their involvement in a student organization, first-generation, working-class, Cambodian American students foster a community that supports interdependent norms, while simultaneously developing skills to navigate independent norms. These efforts produce cultural match and demonstrate agentic qualities through which students reconfigure moments of cultural mismatch to assert their views of legitimacy and reshape the boundaries of cultural capital.
Assessment of Talaromyces Marneffei Infection of the Intestine in Three Patients and a Systematic Review of Case Reports

Abstract Background Hematogenous dissemination of Talaromyces marneffei can result in multiorgan involvement (skin, lung, and reticuloendothelial system involvement); however, few studies have reported intestinal T marneffei infections. We investigated clinical features, management, and patient outcomes concerning Talaromyces-related intestinal infections. Methods Patients with Talaromycosis between August 2012 and April 2019 at The First Affiliated Hospital of Guangxi Medical University, China, were retrospectively analyzed. Patients presenting with intestinal Talaromycosis and endoscopy-confirmed diagnoses were investigated. We also undertook a systematic review of the relevant English and Chinese literature. Results Of 175 patients diagnosed with Talaromycosis, 33 presented with gastrointestinal symptoms, and 31 underwent stool cultures, 1 of which tested positive. Three patients had gastrointestinal symptoms and negative stool cultures, and endoscopic tissue biopsy confirmed a pathological diagnosis. A systematic review of 14 reports on human Talaromycosis identified an additional 16 patients. Fever, weight loss, and anemia were the most common symptoms, along with abdominal pain, diarrhea, and bloody stools. Abdominal computed tomography showed intestinal wall edema and thickening and/or abdominal lymphadenopathy. Endoscopy showed erosion, hyperemia, edema, and multiple intestinal mucosal ulcers. Of the 19 patients, 16 received antifungal therapy, 14 of whom recovered and 2 died. Three patients received no therapy and died. Conclusions Gastrointestinal disseminated Talaromycosis is not rare and can affect the stomach, duodenum, and colon, and may involve the entire digestive tract. Colon is the most common site. Endoscopy is needed for patients presenting with gastrointestinal symptoms in T marneffei-infected endemic areas. Systemic application of effective antifungal therapy can improve the prognosis.
Elementary Functions and Approximate Computing

In this article, we review some of the classical methods used for quickly obtaining low-precision approximations to the elementary functions. Then, for each of the three main classes of elementary function algorithms (shift-and-add algorithms, polynomial or rational approximations, and table-based methods) and for the additional, specific to approximate computing, “bit-manipulation” techniques, we examine what can be done for obtaining very fast estimates of a function, at the cost of a (controlled) loss in terms of accuracy.
Breastfeeding and Related Factors in Afrodescendant Women From Cartagena, Colombia

Objective: To describe practices and related factors to breastfeeding in afrodescendant women from Cartagena de Indias city, Colombia. Material and Methods: Cross-sectional study conducted between 2016 and 2017 in 548 mothers who had under 5 years children from afrodescendant communities. A self-reported questionnaire was applied, asking for sociodemographic variables, breastfeeding time and exclusive breastfeeding, family support and factors related to this practice. Data were analyzed by descriptive statistics and risk estimation by Odds Ratio (OR). Results: Most mothers were young adults (89.8%), having high scholar level (55.2%), family support and they were associated to the public health system. The prevalence of breastfeeding and exclusive breastfeeding during the first 6 months was 91.6% and 80.4%, respectively. Breastfeeding and exclusive breastfeeding practice were associated with mother's age (OR = 3.24, 95% CI= 1.80-5.8) and low mother's educational level (OR = 3.24, 95% CI= 1.8-5.8). Finally, no breastfeeding and the fact of not being performed exclusively was associated with no mother nipples examination, and not or insufficient information supplied about this issue. Conclusion: Breastfeeding practice was associated with mother's age and her educational level as well as with poor preparation to start this practice. Although its prevalence was high, it is necessary to implement policies within health system to encourage its practice and provide measures to solve problems during their development in mothers from vulnerable communities.
Use and Non-Use of Internet Banking Among Elderly People in Nigeria

Existing research in electronic banking has not deeply investigated the determinants of use and non-use of Internet Banking (IB) among the older adults who have been found to exhibit reluctance in using ICT. This study, therefore, investigates the factors that influence use and not use IB among elderly people in the Ibadan metropolis, Nigeria. Survey research design was adopted. Findings indicate that, in addition to the TRA (attitude and subjective norms) and TAM (perceived usefulness and perceived ease of use) variables, trust, self-efficacy, security and facilitating conditions are the factors the elderly population consider in choosing to use or not using IB. Findings also reveal that the non-users have the intention of using IB in the future, while the users have the intention of continuing using IB. This study is novel in the sense that no known study have investigated use and non-use of IB among the elderly in Nigeria in a single study. The paper could assist policymakers in promoting and implementing policies that would ensure the financial inclusion of the elderly and reduce the digital divide between this group and the younger ones.

The productive traits of different potato genotypes in mountainous region of Montenegro

The results of three-year study of productivity for the five leading potato varieties in Montenegro: Riviera and Tresor (early), Kennebec (medium-early), Aladin and Agria (medium-late) are presented. The research was conducted during 2009, 2010 and 2011, on three highly diverse, related to the pedological and climatic conditions, locations in mountainous region of Montenegro: Niksic (800 m.a.s.l.), Kolasin (900 m.a.s.l.) and Žabljak (1450 m.a.s.l.). Field experiments were set up using standard methodology in random block design in four repetitions. The analysis of variance suggested that there were highly significant differences among genotypes (G), investigated years (Y) and locations (L) for potato yield. Apart from individual influence of the factors, their interactions (G x Y, G x L, Y x L, G x Y x L) were also highly significant for investigated trait. In average the highest yield (28.9 t/ha) was established at Kolasin locality. The highest yield of all investigated varieties and localities was measured at variety Agria (30.0tha-1), while the lowest at Riviera (24.6 t ha-1). In this investigation Agria variety was favourable for yield of potato tuber.
Downy mildew outbreaks on grapevine under climate change: elaboration and application of an empirical‐statistical model*

Le climat mondial change. De nombreuses recherches ont deja ete menees pour evaluer les impacts potentiels du changement climatique sur la physiologie des plantes. Cependant, les effets sur les maladies vegetales n'ont pas encore ete etudies en detail. Dans cet article, un modele empirique simulant les infections primaires du mildiou sur la vigne a ete elabore et utilise pour prevoir les dynamiques futures de la maladie en prenant en compte un changement du climat. Ce modele a ete utilise sous les conditions du Modele de Circulation Generale (GCM) et des scenarios d'emergence des epidemies de mildiou ont ete generes dans plusieurs sites dans l'ensemble du monde pour trois decennies a venir: 2030, 2050, 2080. Les resultats suggerent une avance potentielle generale des premiers foyers de maladie, a la fois dans l'hemisphere Nord et Sud, pour les trois annees etudiees. L'avance predite varie d'un minimum d'un jour en Afrique du Sud en 2030 a un maximum de 28 jours au Chili et en Chine en 2080. L'avance du debut d'une epidemie peut conduire a des infections plus severes, dues a la nature polycyclique de l'agent pathogene. Par consequent, des changements dans la periode d'application et la frequence des traitements fongicides peuvent etre attendus a l'avenir, avec une eventuellement augmentation des couts de gestion de la maladie.
Recent Developments and Challenges on AC Microgrids Fault Detection and Protection Systems–A Review

The protection of AC microgrids (MGs) is an issue of paramount importance to ensure their reliable and safe operation. Designing reliable protection mechanism, however, is not a trivial task, as many practical issues need to be considered. The operation mode of MGs, which can be grid-connected or islanded, employed control strategy and practical limitations of the power electronic converters that are utilized to interface renewable energy sources and the grid, are some of the practical constraints that make fault detection, classification, and coordination in MGs different from legacy grid protection. This article aims to present the state-of-the-art of the latest research and developments, including the challenges and issues in the field of AC MG protection. A broad overview of the available fault detection, fault classification, and fault location techniques for AC MG protection and coordination are presented. Moreover, the available methods are classified, and their advantages and disadvantages are discussed.
Fitorremediação de solo contaminado com trifloxysulfuron-sodium por mucuna-preta (Stizolobium aterrimum)

O emprego de especies vegetais que apresentem capacidade fitorremediadora pode ser uma das alternativas para reduzir a persistencia de agroquimicos no ambiente. O objetivo deste trabalho foi avaliar a fitorremediacao do herbicida trifloxysulfuron-sodium em campo, pela especie Stizolobium aterrimum (mucuna-preta), em diferentes densidades populacionais. O delineamento experimental utilizado foi o de blocos casualizados em esquema fatorial 4 x 2, com quatro repeticoes. Os tratamentos foram compostos por quatro densidades de plantio de mucuna-preta (0, 10, 25, e 40 plantas m-2), associadas a duas doses do trifloxysulfuron-sodium (0,00 e 15,00 g ha-1), aplicadas cinco dias apos o preparo do solo para semeadura da mucuna-preta. As plantas fitorremediadoras foram mantidas na area por 65 dias. Apos esse periodo, a area experimental foi novamente sulcada e fertilizada de acordo com a analise do solo, considerando as necessidades da cultura do feijao (Phaseolus vulgaris). Aos 45 dias apos a semeadura do feijao, avaliou-se a altura e a biomassa seca da parte aerea das plantas. Ao final do ciclo da cultura, determinou-se, ainda, o rendimento de graos, o numero de vagens por planta e o peso de 100 sementes. O cultivo previo de mucuna-preta nas densidades populacionais de 10, 25 ou 40 plantas m-2 proporcionou rendimento de graos de feijao nas parcelas tratadas com trifloxysulfuron-sodium no solo semelhante ao obtido na area nao-tratada. A densidade populacional minima desse adubo verde que proporcionou maior rendimento de graos a cultura do feijao foi de 25 plantas por metro quadrado.
Analog I/Q FIR Filter in 55-nm SiGe BiCMOS for 16-QAM Optical Communications at 112 Gb/s

We propose a novel implementation of a complex analog equalization filter for the compensation of frequency-dependent variations in coherent optical links. The analog compensation filter can be used in coherent-lite optical communication links where digital signal processing (DSP) is removed to limit the complexity and power consumption. In these links, the filter can compensate for electrical bandwidth limitations and distortion introduced by chromatic dispersion in the fiber. The complex filter is implemented by combining four distributed analog finite-impulse response (FIR) filters to obtain the necessary response. The filter delays are implemented using active delay cell structures to create a compact solution. The analog filter is implemented in a 55-nm BiCMOS technology and consumes 185-mW core power for five complex filter taps. Performance is evaluated using the S-parameter measurements, noise and linearity measurements, and real-time system experiments using 112-Gb/s 16-QAM-modulated signals.
