Cross cultural differences in loyalty, morality and codes of ethics in African countries: a Nigerian and South African study
Authors: Cant Michael Colin , Wiid Johannes Arnoldus , Prinsloo Carly.
Published: February 2017

Negative behaviour within an organisation affects the reputation, and the operations of an organisation. The factors that have an influence on behaviour include morality, ethics and loyalty. With numerous influences on morality and loyalty alike, ethical codes are varying among countries, organisations and individuals. The fluctuating nature of codes of ethics means that organisations working together, which are based in different regions, have different expectations and perceptions of ethics based on the codes of ethics established within their organisations. The results indicated that small business owners in leading African countries (South Africa and Nigeria) have similar views on moral behaviour and concern for ethical misconduct in the workplace
Earnings management, directors’ discretions and information content affecting discretionary accruals of Malaysian publicly listed companies
Authors: Choong Yap Voon , Chan Kok Thim , Murugeshu John Stanley
Published: February 2017

Managers have reporting discretion permitted by accounting standards over a combination of earnings management choices. The objective of this study is to identify the types of discretionary accounting choices that are indicative of earnings management. Based on a sample of 947 companies listed on the Malaysian stock exchange, the results indicate that a number of firm specific financial variables that proxy for agency cost, political costs and information asymmetry capture discretionary accruals behaviour. This study also seeks to examine the explanatory power of the earnings management in predicting future earnings and firm value. The results indicate that discretionary accruals can improve the informativeness of a firm’s current and past earnings when predicting future earnings and share price
The performance of socially responsible investment funds and exchange-traded funds: Evidence from Johannesburg stock exchange
Authors: Marozva Godfrey
Published: February 2017

The research reported in this article explored how the JSE SRI Index performed relative to exchange-traded funds during the period of economic growth as well as during the period of economic decline between 2004 and 2014. The JSE SRI Index and exchange traded funds are analysed by a single factor model as well as other risk-adjusted performance measures including the Sharpe ratio, the Treynor ratio and the M-squared ratio. The single-factor model regression results suggest that during the period of economic growth the JSE SRI index neither significantly outperformed nor underperformed the exchange-traded funds. However, the JSE SRI Index significantly underperformed the exchange-traded funds during the period of economic decline. Further tests that engaged other risk-adjusted measures indicated that the exchange-traded funds performed better than the JSE SRI index in both periods. Based on this research it is recommended that further research be conducted using models that can control for the liquidity difference in funds.
Disclosure quality in Tunisian annual reports
Authors: Chakroun Raida , Hussainey Khaled
Published: February 2017

This paper explores disclosure quality and its determinants in the Tunisian context. More specifically, we followed Beest and Braam (2012)’s approach in measuring disclosure quality and examined if disclosure quality and disclosure quantity shared the same determinants. We used a sample of 56 annual reports from non-financial companies listed on the Tunisian Stock Exchange for the years 2007 and 2008. Our results showed that board independence (managerial ownership) affects negatively (positively) disclosure quality. However, the results showed that there were different determinants of disclosure quality and quantity. We contribute to disclosure studies by being the first study to examine disclosure quality in Tunisia. In addition, this study enables us to provide the Tunisian companies’ stakeholders (like regulators and managers) with a diagnosis of the determinants of disclosure quality and quantity.
Government-linked banks’ performance in Jordan
Authors: Ghabayen Mohammad Ahid , Hardan Ahmad Omar , Jaradat Zaid , Alshbiel Mohannad
Published: February 2017

The main objective of this study is to examine the relationship between government ownership and bank performance in Jordan. The banking sector has been widely ignored in the past corporate governance studies due to its strict system. Using a panel data from 2004 to 2013 (147 observations/years), the multiple regression analysis shows that increasing the percentage of shareholdings leads to higher profitability. Additional government-linked banks (GLBs) generally outperform their unlinked counterparts. However, their outperformance is contingent to the significance percentage of the shareholdings. On other words, if the government shareholdings are not significant (less than 10%) the government ownership does not make a significant difference in the performance. Using panel data provide us with a significant roles played by the period of the study. The banks show increasing in their performance through the period of this study. However, the size and the age of the banks are found to be insignificant while the leveraged banks significantly underperform their counterparts. The results of this study might be of interest of potential investors, policy makers, governance agencies and information users.
Does a high dividend payout ratio signal proper corporate governance or high agency cost of debt?
Authors: Jabbouri Imad , El Attar Abdelillah
Published: February 2017

This paper examines the relationship between dividend policy and the cost of debt in Morocco. The results show that high dividend payments reflect a low level of agency costs of equity and low information asymmetries. Consequently, creditors demand lower return for providing their capital to high dividend-paying firms. The findings reveal that creditors are less concerned with agency costs of debt. The study shows that the negative relationship between dividend payout ratios and cost of debt is more pronounced in firms with higher information asymmetries.
Determinants of voluntary disclosure of internal control weaknesses in Tunisia
Authors: Kharraz Hamed , Ferchichi Jihene
Published: February 2017

The main objective of this research is to examine the determinants which can push the auditors to reveal the weaknesses of the internal control system in companies listed on the Stock Exchange Securities of Tunisia. We are particularly interested in determinants related to corporate governance, ownership structure and some company characteristics. The conceptual framework referred to this work is the agency theory. We concluded from the results of the logistic regression model that the probability of disclosure of internal control weaknesses was not significantly associated with corporate governance and ownership structure. However, some other company characteristics, e.g. the size are strongly related with probability of firms disclosing internal control weaknesses.

Compliance and transparency of German supervisory board compensation
Authors: Koch Rosemarie
Published: February 2017

Due to some new developments in the German Corporate Governance Codex (GCGC) as well as the introduction of new laws several aspects of the supervisory board compensation are subject to change. In a first step we analyze the size and structure of DAX 30 companies’ supervisory board compensation. One novelty of the article is that we perform this analysis on a person specific level instead of relying on firm level data. In a second step, we examine how well DAX 30 firms comply with the GCGC on supervisory board compensation both with regard to the recommended structure and with regard to the recommended detail in disclosure. We construct a compliance scoring model and find that overall a score of 70 % compliance has been reached.
International private benefits of control: New evidence
Authors: Nguyen Nhut H. , Liu Yubo
Published: February 2017

The 1998 Asian Financial Crisis and more recent corporate scandals in the U.S. have triggered an increased attention of researchers and policy makers on the agency problem between controlling shareholders and minority investors. One respect of this problem is the private benefits of control. In this paper, we investigate the relationship between investor protection and private benefits of control. We find consistent evidence with Dyck and Zingales (2004) that the degree of investor protection still matters in curbing private control benefits for the more recent period 1999-2007. More importantly, we find that private benefits of control have decreased significantly over time. Finally, our results show weak evidence of differential decreases in the value of control for weak and strong investor protection countries.

Corporate governance in the context of the recovery of distressed firms: A case study in Brazilian air transportation sector
Authors: Almeida Vinicio de Souza , Romano Patrícia Ribeiro
Published: February 2017

Corporate governance is a set of practices and processes of board and executives’ coordination and control that aims at protecting the interests of shareholders and others affected by the value of the company. The discussions and disputes involving shareholders in Brazil and a new corporate law aimed at improving governance practices in the country, reducing the cost of capital of the company and contributing to national economic growth. In this study, we compared the theoretical evidence on the governance structure of airlines with the reality of a large company in the sector in Brazil. The results indicate that a wrong architecture of ownership and control combined with the non-corporate governance system may result in financial distress for an organization.
Magnetic field effect on convective heat transfer in corrugated flow channel
Authors: Heidary Hadi , Kermani Mohammad , Dabir Bahram
Published: February 2017

In this study heat transfer and fluid flow analysis in a wavy channel is numerically studied, while a magnetic field is applied in transverse direction to the main flow stream. Recently in a numerical study, we have observed that usage of wavy channel instead of straight one enhances heat exchange between the core flow and hot walls. On the other hand, the usage of magnetic field transverse to hot walls can enhance heat transfer in a straight channel. In this paper, we would like to examine if presence of these two methods simultaneously is useful for enhancement of heat exchange. For this purpose, the governing equations are numerically solved in the domain by the control volume approach based on the SIMPLE technique. Numerical studies are performed over a range of Reynolds number, Hartmann number, and the wave amplitude. From this study, it is concluded that heat transfer in channels can be enhanced by the usage of magnetic field or usage of wavy channel instead of a straight one. But simultaneous usage of magnetic field and wavy channel is not recommended.

Published: February 2017

In this study, BaFe1−xAlxO3-δ (0 ≤ x ≤ 0.3) perovskite-type oxides were prepared by sol-gel method using citric acid as chelating agent. The samples were subjected to various calcination temperatures in order to investigate the physicochemical properties of the oxide affected by the parameter. Thermogravimetric analysis, Fourier transform infrared spectroscopy and X-ray diffraction (XRD) techniques are used to explore precursor decomposition and to establish adequate calcination temperature for the preparation of the nano-powders. The studied compounds have hexagonal crystal structure at the temperature of 1123 K. The samples obtained after calcination at 1123 K were characterized by XRD, Brunauer-Emmett-Teller surface area analysis, scanning electron microscopy, powder size distribution and electrical conductivity. The microstructure and morphology of the compounds show that the particles are nearly spherical in shape and are partially agglomerated. The highest surface area and total pore volume are achieved for BaFe0.8Al0.2O3-δ oxide. Temperature dependence of electrical conductivity shows a semiconducting behavior.

In accordance with the hypothesis about the mechanism of extracting carbon-containing components from rice husk by liquid extractants, proper extractants were selected. The effect of main technological factors including process temperature, time and concentration of the extractants was determined.
Use of Automated Vehicle Location Data for Route- and Segment-Level Analyses of Bus Route Reliability and Speed
Authors: Hu Wen Xun , Shalaby Amer
Published: February 2017

Reliability and speed are arguably the most important indicators of surface transit performance for both operators and passengers. They can be influenced by a variety of factors, including service characteristics of bus routes, physical infrastructure, signal settings, traffic conditions and ridership patterns. These factors have often been analyzed individually for their impact on transit reliability or speed. Studies considering more than one factor tend to use one or two transit routes to explore their effects. The study that is the subject of this paper proposed an evaluation framework to guide the selection of an appropriate reliability measure. Regression analysis was applied subsequently to determine the factors that exhibit a statistically significant relationship with transit reliability and speed at both the route and segment levels. Automated vehicle location data of a bus route sample that is representative of the entire bus network in the City of Toronto, Ontario, Canada were used. Features significantly associated with reliability and speed were compared. The results showed that lower transit reliability and speed are significantly associated with the increase in service distance, signalized intersection density, stop density, volume of boarding and alighting passengers, and traffic volume. By segregating bus route segments on the basis of the presence of transit signal priority, the results of the segment-level model demonstrated the beneficial impact of transit signal priority on improving transit reliability.

This study was conducted to draw linkage between intake pattern of Choline and nutritional status of pregnant women in 3rd trimester and assess the contribution of agriculture retrospectively to increase its intake. Retrospective data was therefore, collected from United States Development Agency (USDA) data base on Choline content of common vegetable products of Bangladesh. Recommended Choline intake for the pregnant women in 3rd trimester is 450mg/day. The present study conducted using 24 hours recall method revealed that average Choline intake among the study respondents was 317 mg/day which meet 71 percent of the requirement. Majority (72.7%) of the women took Choline below the recommended level (450 mg/day). It is remarkable that 56.7, 55.3 and 52.0% of the pregnant women were deficient in calorie, protein and fat intake respectively. This study found that 54% respondents mothers were within normal Body Mass Index (BMI) while 33% were overweight, 5.3% were underweight and 8.0% were obese. Choline intake status was poor among the pregnant women commencing delivery complication and indicating high prevalence of mental retardation for newborn.The Agriculturists 2016; 14(2) 86-94

The Two-Edged Sword as Image of Civil Power for Fisher and More
Authors: Hatt Cecilia A.
Published: February 2017

When Sir Thomas More was questioned about Henry VIII’s Act of Supremacy, he answered that the Statute was like a two-edged sword: if a man agreed to it he would lose his soul, but if he refused it, he would lose his earthly life. John Fisher, the bishop of Rochester, used the same image at his examination. This article examines the image of the two-edged sword in respect of both its use by More and of its Scriptural analogue and suggests reasons why both Fisher and More used it and how their use of it differed.
Le dialogue ficinien : lieu d’un itinéraire mystique
Authors: Reynaud Julie , Galland Sébastien
Published: February 2017

Marsilio Ficino, the master of Florence’s Platonic Academy, makes scant use of dialogue. He reserves it for the analysis of the soul’s itinerary, which leads her from skepticism and desperation to conversion and then joy. The soul is at first unaware of her own divinity and only through slow progression can she achieve genuine mystical experience. The Theological Dialogue between God and the Soul, which is proposed here in a yet unpublished French version, exposes the basic distress of any quest of the self and quest of God. As a Daughter feeling she has been abandoned, the soul addresses her Father. He discloses to her the paradoxical nature of God who has established extreme intimacy with his creatures. But for her to be able to perceive this, the soul will have to give up rational and intellectual understanding and admit that she only needs to ardently desire and love.
Cyclic Competition and Percolation in Grouping Predator-Prey Populations
Authors: Lütz Alessandra , Cazaubiel Annette , Arenzon Jeferson
Published: February 2017

We study, within the framework of game theory, the properties of a spatially distributed population of both predators and preys that may hunt or defend themselves either isolatedly or in group. Speciﬁcally, we show that the properties of the spatial Lett-Auger-Gaillard model, when different strategies coexist, can be understood through the geometric behavior of clusters involving four effective strategies competing cyclically,without neutral states. Moreover, the existence of strong ﬁnite-size effects, a form of the survival of the weakest effect, is related to a percolation crossover. These results may be generic and of relevance to other bimatrix games.

Published: February 2017

Human MLH3 (hMLH3) gene has been suggested to play a role in the DNA mismatch repair mechanism, while it may also be associated with abnormal spermatogenesis and subsequently male infertility. The aim of the present study was to investigate possible relationships between the single nucleotide polymorphism (SNP) rs175080 in the MLH3 gene of males and the embryological results in couples undergoing intracytoplasmatic sperm injection-embryo transfer (ICSI-ET) treatments. A total of 132 men volunteered for the study and gave written informed consent. All couples were subjected to ICSI-ET treatments in the years 2010 to 2012. The couples were divided into three groups according to the genotype of their husbands: the wild type GG (n = 28), the heterozygotic type GA (n = 72) and the mutant type AA (n = 32). Significantly lower sperm concentration and progressive motility were observed in the AA group as compared to the other two groups (Concentration: 14.57 ± 4.9 mil/mL in AA, 38.3 ± 5.4 mil/mL in GA and 41.03 ± 6.8 mil/mL in GG, p < 0.05, mean ± standard error of the mean—SEM). However, significantly better embryological results (mean score of embryo quality–MSEQ) were found in the AA (8.12 ± 0.5) and the GA group (7.36 ± 0.4) as compared to the GG group (5.82 ± 0.7), (p < 0.05). Clinical pregnancy rate was significantly higher in the AA genotype group (43.8%) and the GA group (30.6%) than in the GG group (14.3%), (p < 0.05). Live birth rate was not different. It is suggested for the first time that the deteriorating effect of the mutant type on sperm characteristics does not impact on embryo development after fertilization in vitro.

Published: February 2017

The peritoneal dialysis (PD) patient population has grown rapidly in the past few years with concern over poor early outcomes. We report 6-month outcomes of incident PD patients in an experienced program with a strong focus on quality care. We analyzed data from an Institutional Review Board (IRB)- approved registry of all incident PD patients from January 1, 1991, to December 31, 2013, with follow-up to June 30, 2014. Time at risk began on the first day of training. Age, gender, race, diabetes mellitus (DM), Charlson comorbidity index (CCI), and albumin were collected at PD start. Exit-site infection (ESI), peritonitis, hospitalizations, and reasons for stopping PD were recorded. Multivariate analysis was done to examine outcomes.

Published: February 2017

We present the Late-Type Extension to the Motion Verified Red Stars (LaTE-MoVeRS) catalog, containing 46,463 photometric late-type (>M5) dwarfs within the Sloan Digital Sky Survey (SDSS) footprint. Proper motions were computed for objects combining astrometry from the SDSS Data Release 12 (DR12), the Two-micron All-Sky Survey (2MASS) Point Source Catalog, and the Wide-field Infrared Survey Explorer (WISE) AllWISE data sets. LaTE-MoVeRS objects were required to have significant proper motion (

). Using the LaTE-MoVeRS sample and Gaia Data Release 1, we estimate Gaia will be ∼64% complete for very low-mass objects (>M5) in comparison to the combined SDSS+2MASS+WISE data set (

). We computed photometric distances and estimated stellar effective temperatures for the LaTE-MoVeRS catalog. The majority of the dwarfs in the sample have distances

pc and

K. Thirteen objects that have not been previously identified as nearby objects were identified within LaTE-MoVeRS with estimated photometric distances within 25 pc. We also identified one new object that has not been previously identified with a large amount of excess mid-infrared flux  (2MASS J11151597+1937266). This object appears to be an L2γ at ∼50 pc showing spectroscopic signs of a flaring event (e.g., strong hydrogen Balmer emission lines). This object does not exhibit kinematics similar to any known kinematic association. The LaTE-MoVeRS catalog is available through SDSS CasJobs and VizieR.

We present spatial correlations of galaxies and IGM neutral hydrogen H i in the COSMOS/UltraVISTA 1.62 deg2 field. Our data consist of 13,415 photo-z galaxies at z ∼ 2–3 with

and the Lyα forest absorption lines in the background quasar spectra selected from SDSS data with no signature of damped Lyα system contamination. We estimate a galaxy overdensity δ
gal in an impact parameter of 2.5 (proper) Mpc, and calculate the Lyα forest fluctuations

whose negative values correspond to the strong Lyα forest absorption lines. We identify weak evidence of an anti-correlation between δ
gal and

with a Spearman’s rank correlation coefficient of −0.39 suggesting that the galaxy overdensities and the Lyα forest absorption lines positively correlate in space at the ∼90% confidence level. This positive correlation indicates that high-z galaxies exist around an excess of H i gas in the Lyα forest. We find four cosmic volumes, dubbed A
obs, B
obs, C
obs, and D
obs, that have extremely large (small) values of δ
gal ≃ 0.8 (−1) and

, three of which, B
obs–D
obs, significantly depart from the δ
gal–

correlation, and weaken the correlation signal. We perform cosmological hydrodynamical simulations and compare with our observational results. Our simulations reproduce the δ
gal–

correlation, agreeing with the observational results. Moreover, our simulations have model counterparts of A
obs–D
obs, and suggest that the observations pinpoint, by chance, a galaxy overdensity like a proto-cluster, gas filaments lying on the quasar sightline, a large void, and orthogonal low-density filaments. Our simulations indicate that the significant departures of B
obs–D
obs are produced by the filamentary large-scale structures and the observation sightline effects.
Galactic Angular Momentum in Cosmological Zoom-in Simulations. I. Disk and Bulge Components and the Galaxy–Halo Connection

Published: February 2017

We investigate the angular momentum evolution of four disk galaxies residing in Milky-Way–sized halos formed in cosmological zoom-in simulations with various sub-grid physics and merging histories. We decompose these galaxies, kinematically and photometrically, into their disk and bulge components. The simulated galaxies and their components lie on the observed sequences in the j
*–M
* diagram, relating the specific angular momentum and mass of the stellar component. We find that galaxies in low-density environments follow the relation

past major mergers, with

in the case of strong feedback, when bulge-to-disk ratios are relatively constant, and

in the other cases, when secular processes operate on shorter timescales. We compute the retention factors (i.e., the ratio of the specific angular momenta of stars and dark matter) for both disks and bulges and show that they vary relatively slowly after averaging over numerous but brief fluctuations. For disks, the retention factors are usually close to unity, while for bulges, they are a few times smaller. Our simulations therefore indicate that galaxies and their halos grow in a quasi-homologous way.
Myalgia in Patients with Dermatomyositis and Polymyositis Is Attributable to Fasciitis Rather Than Myositis: A Retrospective Study of 32 Patients who Underwent Histopathological Examinations
Authors: Noda Kentaro , Yoshida Ken , Ukichi Taro , Furuya Kazuhiro , Hirai Kenichiro , Kingetsu Isamu , Kurosaka Daitaro
Published: February 2017

Objective.

To determine the association between fasciitis and the clinical variables in patients with dermatomyositis (DM) and polymyositis (PM).

Methods.

We retrospectively reviewed the medical records of 32 patients (24 DM, 8 PM) with newly diagnosed DM and PM and in whom fascia and muscle specimens were histopathologically examined. The relationship between fasciitis and the clinical variables was statistically analyzed. These included age, sex, myalgia, muscle weakness, creatine kinase (CK) and aldolase activities, anti-Jo1 antibody, interstitial lung disease, and malignancy.

Results.

Twenty (62.5%) of the 32 patients who underwent the histopathological examination of a fascia specimen had fasciitis, including 18 (75%) of 24 patients with DM and 2 (25%) of 8 patients with PM. The frequency of fasciitis was significantly higher among the patients with DM than among the patients with PM (p < 0.05). Histopathologically, fasciitis in PM was very mild in comparison to that in DM. The frequency of myalgia in patients with fasciitis was significantly higher than that in patients without fasciitis (p < 0.05). However, myalgia was not associated with myositis. There were no significant differences in the patients with and without fasciitis in age, sex, manual muscle test 8 scores, CK or aldolase activities, or the presence of anti-Jo1 antibodies and malignancy.

Conclusion.

The frequency of fasciitis was significantly higher among patients with DM than among those with PM. Fasciitis, rather than myositis, was associated with myalgia.

La visite à domicile est un formidable outil de prévention pour la puéricultrice de pmi . Les observations des interactions mère-enfant vont lui permettre d’étoffer un travail de soutien et d’accompagnement auprès de familles vulnérables et de mettre en place un maillage sécurisant en partenariat pluridisciplinaire. Cette alliance parent-professionnelle établie au fil des rencontres ne doit pas rester confinée au domicile mais doit favoriser une ouverture vers l’extérieur.
Forme solide et École solide : comment penser une nouvelle grammaire (architecturale) scolaire ?
Authors: Mabilon-Bonfils Béatrice , Martin Virginie
Published: February 2017

La forme scolaire est questionnée de toutes parts par des mutations qui en affectent autant la manière de penser, d’organiser et de dispenser les savoirs que la fonction sociale et politique. A la trans-modernité liquide répond une verticalité de la forme scolaire solide que le double tournant numérique et global n’affectent pas encore. Le savoir-relation suppose une nouvelle grammaire scolaire ouvrant à l’école extensive.

Cet article traite de la question du rapport de la pédagogie à l’espace à travers une analyse proxémique des interactions de classe. Il s’agit spécifiquement d’étudier l’impact de certaines variables spatiales comme le positionnement, la distance ou la disposition, sur le comportement des étudiants dans le cadre d’enseignements universitaires dispensés dans une salle de classe expérimentale : le SpaceTech. Des observations filmées ont été réalisées avec des caméras GoPro et ont donné lieu à des traitements statistiques portant sur un échantillon de 115 étudiants. Les résultats obtenus ont permis l’identification d’un certain nombre de corrélations entre l’espace et le comportement pédagogique.

Les espaces de discussion sur Internet comme dépassement des communautarismes ? Le cas de l’agora virtuelle libanaise.
Authors: Chaker Rawad
Published: February 2017

La question des identités et des communautarismes n’aura jamais été, durant notre histoire contemporaine, aussi prégnante qu’aujourd’hui. Cet article se penche sur l’enjeu des espaces de discussion sur Internet et de ses effets sur la nature des interactions en ligne dans un contexte marqué par le communautarisme. L’école pourrait-elle enseigner la citoyenneté grâce aux outils numériques de communication et d’information ? Nous tentons ici de mettre la lumière sur les effets d’éloignement ou de rapprochement communautaire que ce type d’échange permet d’observer. Nous nous posons la question de savoir si l’agora virtuelle s’inscrit dans un paradigme potentiel d’espace public démocratique, ce qui le positionnerait alors dans le débat public plus général sur Internet et les enjeux éducatifs et citoyens. Nous mobilisons le régime de la cité civique tiré de la théorie des Économies de la Grandeur comme matrice méthodologique afin d’analyser un espace d’échange électronique sur 6 sites d’information libanais, qui relèvent typiquement d’un contexte marqué par le morcellement politique et communautaire.

Polymorphisms located within the MHC have been linked to many disease outcomes by mechanisms not yet fully understood in most cases. Variants located within untranslated regions of HLA genes are involved in allele-specific expression and may therefore underlie some of these disease associations. We determined sequences extending nearly 2 kb upstream of the transcription start site for 68 alleles from 57 major lineages of classical HLA class I genes. The nucleotide diversity within this promoter segment roughly follows that seen within the coding regions, with HLA-B showing the highest (∼1.9%), followed by HLA-A (∼1.8%), and HLA-C showing the lowest diversity (∼0.9%). Despite its greater diversity, HLA-B mRNA expression levels determined in 178 European Americans do not vary in an allele- or lineage-specific manner, unlike the differential expression levels of HLA-A or HLA-C reported previously. Close proximity of promoter sequences in phylogenetic trees is roughly reflected by similarity of expression pattern for most HLA-A and -C loci. Although promoter sequence divergence might impact promoter activity, we observed no clear link between the phylogenetic structures as represented by pairwise nucleotide differences in the promoter regions with estimated differences in mRNA expression levels for the classical class I loci. Further, no pair of class I loci showed coordinated expression levels, suggesting that distinct mechanisms across loci determine their expression level under nonstimulated conditions. These data serve as a foundation for more in-depth analysis of the functional consequences of promoter region variation within the classical HLA class I loci.

La investigación didáctica ha destacado el papel de la enseñanza problematizada en el aprendizaje de las ciencias. Este modelo de enseñanza se caracteriza por organizar las unidades en torno a problemas y proponer un plan de investigación para avanzar en su solución que exige que los conceptos y modelos sean introducidos de manera funcional, como posibles soluciones al problema planteado. En este artículo presentamos una unidad problematizada para la enseñanza de la física cuántica en los cursos introductorios de física, analizando con detalle la estrategia seguida para construir un modelo que explique la emisión y absorción de radiación.
Bases metodológicas para el uso de la modelización en la enseñanza y comprensión de la dinámica litoral
Authors: Mayoral García-Berlanga Olga , Talavera Ortega Marta
Published: February 2017

El presente trabajo plantea el uso de la modelización para mejorar la comprensión de ciertos problemas ambientales del litoral. En concreto se incluye la base metodológica que se empleó para la construcción de un modelo consensuado de enseñanza que recogiera los factores ambientales y antrópicos que determinan la dinámica de sedimentos del litoral. La elaboración del modelo de consenso contó con la colaboración de expertos en sedimentología y ecosistemas costeros, así como de profesorado de diferentes niveles educativos (desde Primaria hasta de Universidad), que ayudaron a seleccionar las edades con las que se podría trabajar esta modelización, colaborando así mismo en la elaboración del modelo gráfico que serviría de base de una intervención didáctica futura.
Comparison of in vitro Fertilization/Intracytoplasmic Sperm Injection Outcomes in Patients receiving Recombinant Human Luteinizing Hormone vs Human Menopausal Gonadotropin Supplementation
Authors: Rajinikanthan DB Usha , Varma Thankam
Published: February 2017

Objectives

To compare the outcome of recombinant human luteinizing hormone (rh-LH) and human menopausal gonadotropin (hMG) supplementation in women undergoingin vitrofertilization/ intracytoplasmic sperm injection (IVF/ICSI) with recombinant follicle stimulating hormone (FSH) in the long gonadotropinreleasing hormone (GnRH) agonist stimulation protocol.

Materials and methods

It was a retrospective analysis of the case records of 90 consecutive women who underwent nondonor IVF/ICSI cycle with long GnRH agonist. All women received recombinant FSH on day 2/3 of the programming cycle. When the level of LH was < 0.5 mIU/mL during any phase of stimulation, then addition of LH either as rh-LH or hMG is given along with recombinant FSH.

Results

The number of oocytes collected, the number of oocytes in metaphase II (MII), and fertilization rate were similar in both groups. In addition, the mean number of embryos produced per cycle and the mean number of frozen embryos per cycle were similar in both groups. The cost of gonadotropin is similar in both groups. The ongoing pregnancy rate at 12 weeks was 20.4% after rh-FSH + hMG and 29.2% after rh-FSH + rh-LH (p-value = 0.092).

Conclusion

Supplementing recombinant FSH with recombinant LH (rh-LH) when compared with hMG does not show statistically significant increase in pregnancy rates. However, this study was a pilot venture to introduce the rh-LH into our practice and further randomized study is required to substantiate its use in assistive reproductive technology.

Do governo por leis à governança por números: breve análise do Trade in Service Agreement (TISA).
Authors: Saldanha Jânia Maria Lopes , Mello Rafaela Da Cruz , Limberger Têmis
Published: February 2017

O artigo propõe-se a analisar, em um contexto de globalização e mundialização de atores internacionais, o fenômeno de ressignificação de estruturas delineadas na modernidade, como é o caso do Estado, direito e governo. Partindo-se da noção de que as relações transnacionais que permeiam a paisagem político-jurídica atual são incapazes de ser compreendidas somente com conceitos advindos da modernidade, examina-se a estética do caos jurídico, da formação de um direito transnacional e das tentativas de superação de um governo por leis por uma governança por números. Essa tentativa é demonstrada pela substituição do sonho moderno da harmonia jurídica pelo cálculo matemático pelo atual ideal de harmonia pela estatístico. As regras clássicas de direito passam a conviver com o crescimento de normas programáticas que estimulam o poder das empresas transnacionais e os valores de mercado ao fomentarem a concorrência entre os sistemas jurídicos e a desregulamentação a fim de atender aos interesses econômicos. Utilizando-se o método dialético para opor a incompletude das ideias diante da força das coisas, a análise desse cenário será feita a partir de revisão bibliográfica e da observação do Acordo sobre Comércio de Serviços (TISA), acordo entre diversos países que tem como objetivo velado a privatização de serviços públicos e a desregulamentação para favorecer grandes empresas. Conclui-se que o TISA serve para corroborar a afirmação de que a globalização fomenta a passagem de um governo por leis para uma governança por números, a qual gera mudanças tanto na sociedade internacional como nos sistemas jurídicos internos dos Estados.
