Published: May 2017

Aim

Adolescence is a developmental period often associated with high-risk behaviors. While some risk-taking behavior is considered normative in adolescents, research has indicated an association between risky behaviors and mental ill-health. The current research aimed to examine the relationship between anxiety and depression with the occurrence of high-risk behaviors in adolescents and also determine the predictive factors of these main variables.

Methods

A descriptive, cross-sectional, correlational design was used to collect data from 399 adolescents between the ages of 14 and 19 residing in Qazvin, Iran using the Revised Child Anxiety and Depression Scale (RCADS) and the Iranian Adolescents Risk-taking Scale (IARS) between the period of October and November 2015. Data analysis included descriptive and inferential statistics powered by SPSS (v. 23).

Results

Mean scores for anxiety, depression and risky behaviors were 37.70 ± 21.11 and 80.76 ± 31.30, respectively. Participants’ frequency of suicidal thoughts (β = 0.126, p < 0.05) positively predicted anxiety and depression, while age (β = −0.126, p < 0.01) and self-confidence (β = −0.307, p < 0.001) negatively predicted anxiety and depression. Moreover, having friends that smoke (β = 0.366, p < 0.001), suicidal thoughts (β = 0.127, p < 0.01), and the strength of suicidal thoughts (β = 0.100, p < 0.05) were positive predictors of occurrence of risky behaviors. Furthermore, religious belief (β = −0.204, p < 0.001) negatively predicted occurrence of risky behaviors in Iranian adolescents. Male respondents were more likely to have higher level of occurrence of risky behaviors than females (β = −0.193, p < 0.001).

Conclusion

Findings of the present study suggest that anxiety and depression positively and significantly predict the occurrence of risky behaviors in addition to having friends that smoke, suicidal thoughts, and strong suicidal thinking. The implications of these findings have relevance for screening, prevention, and treatment interventions targeting mental health in adolescents.
Study on a Harmonic Measurement and Analysis Method for Power Supply System
Authors: Wu Tiecheng , Jiang Dao , Wang Yazi , Lei Aiju
Published: May 2017

In the power supply system of high speed railway, the generated harmonics can not only influence the electric energy quality of power system, occur the voltage fluctuation and flicker, and affect the service life of traction equipment and traction transformer of electric power substation, but also cause the secondary protection misoperation of automatic control system, and affect the normal operation of the train. With the increase of overhead contact line transmission, the generated harmonics increased the communication interference. Therefore, on the basis of analyzing the generation and spectrum of harmonics in power system, an improved S transform method is introduced in order to propose a harmonic measurement and analysis method based on improved S transform for power supply system of high speed railway in this paper. The proposed method can effectively realize the harmonic measurement and analysis of power supply system. In order to testify the effectiveness of the proposed harmonic measurement and analysis method, Yingkou substation of Harbin-Dalian high speed railway is selected in here. The actual analysis calculation and experiment results show that the proposed method can effectively measure and analyze the harmonic in the power supply system of high speed railway. It provides a theoretical basis for solving the practical engineering problem of power supply.

Das historische Ereignis der Wende gehört zu einem der bedeutendsten Stoffe der zeitgenössischen deutschsprachigen Literatur. Der Zeitpunkt der Entstehung hat dabei einen nicht zu unterschätzenden Einfluss auf Form und Stil des literarischen Werkes: Von einer zunächst eher ironisch geprägten Herangehensweise über einen nostalgisch-verklärenden Ansatz bis zu den jetzigen Tendenzen klassischen Erzählens wird in dem vorliegenden Aufsatz beispielhaft dargelegt, wie sich der Blickwinkel der Autoren auf die Wendeereignisse verändert und wie diese unterschiedlichen literarischen Zeugnisse im Deutschunterricht eingesetzt werden können.
Studiengang Fachdeutsch Wirtschaft mit Schwerpunkt Agrar- und Ernährungsindustrie an der Universität Thiès / Senegal
Authors: Gueye Ousmane
Published: May 2017

An der neu gegründeten Universität zu Thiès in der westafrikanischen Republik Senegal ist im Rahmen der »Langues Etrangères Appliquées« (LEA) eine Fachfremdsprachen-Abteilung errichtet worden, an der u.a. Deutsch als Wirtschaftssprache in einem dreijährigen Studiengang unterrichtet wird. Die Studienreform richtet sich formal an den Zielen des Bologna-Prozesses aus. Dem neuen Lernprogramm liegen Ansätze zugrunde, die für eine Neuorientierung des Wirtschaftsdeutsch-Unterrichts im senegalesischen Raum plädieren. Im Gegensatz zu bislang existierenden LEA-Abteilungen (Universität Cheikh Anta Diop de Dakar und Gaston Berger de Saint Louis) umfasst die Ausbildung an der Universität de Thiès auch eine Einführung in die deutschsprachige Literatur; der Akzent der fachsprachlichen Ausbildung liegt auf Fachlexik, Fachsprachengrammatik sowie Fachtext. Einen Schwerpunkt bildet die Ausbildung im Sektor Agrar- und Ernährungsindustrie, womit in unmittelbarer Praxisrelevanz u.a. lokale Produkte gefordert werden. Hauptlernziel der Ausbildung ist die qualifizierte Teilnahme an in der Agrar- und Ernährungswirtschaft typischerweise vorkommenden Kommunikationssituationen.
Intertextualität und fremdsprachliches Lernen in Südosteuropa. Zur Verbindung von sprach-, literatur- und landeskundedidaktischen Unterrichtsstrategien am Beispiel von Texten Johann Wolfgang von Goethes, Franz Kafkas und Christian Krachts
Authors: Fornoff Roger
Published: May 2017

Vor dem Hintergrund einer kritischen Situationsbeschreibung des universitären Literaturunterrichts an südosteuropäischen Germanistiken wird ein alternatives, aus dem literaturwissenschaftlichen Bereich entwickeltes Unterrichtskonzept vorgestellt, das anhand der Auseinandersetzung mit drei Romananfängen der deutschen Literatur (Goethe: Wahlverwandtschaften [1809], Kafka: Der Verschollene [1927] und Kracht: Faserland [1995]) literarische, sprachliche und landeskundliche Lernprozesse zusammenführt. Methodisch orientiert sich das Vermittlungskonzept, das im Sommersemester 2011 am Lehrstuhl für Germanistik der Universität Belgrad erfolgreich durchgeführt wurde, an Julia Kristevas poststrukturalistisch inspirierter Intertextualitätstheorie. Sie wird insofern für fremdsprachendidaktische Zwecke adaptiert, als die ausgewählten Romananfänge innerhalb der vorgestellten Unterrichtsreihe den Ausgangspunkt für eine Vielzahl von intertextuellen Vernetzungen bilden, indem sie a) miteinander über narratologische und literarhistorische Gesichtspunkte verknüpft b) mit selbstverfassten Texten der Studierenden in ein Verhältnis gesetzt und c) in den Kontext nichtfiktionaler Texte gestellt werden, die in dezidiert fremdsprachendidaktischer Perspektive ihre landeskundlich-kulturbezogenen Bedeutungsaspekte aufgreifen. Mit dieser Verfahrensweise verbindet sich die Absicht, die literarischen Ausgangstexte über den Nachvollzug von intertextuellen Bezügen, Relationen und Verweisungen inhaltlich, formal und stilistisch zu erhellen und als Träger sowohl von unmittelbar (fremd-)sprachlichen als auch von literarisch-literaturhistorischen, fremdkulturell-landeskundlichen und personal-subjektgebundenen Sinn- und Bedeutungsgehalten zu dechiffrieren. Der Artikel mündet in ein Referat der Evaluation des Unterrichtskonzepts durch die Studierenden und damit in eine Reflexion über dessen Stärken und Schwächen.

Videokonferenzen im DaF-Bereich? Überlegungen zu Möglichkeiten und Grenzen am Beispiel »Skype in the classroom«
Authors: Bahlo Nils , Paul Christine , Topaj Nathalie , Steckbauer Daniel
Published: May 2017

Die Entwicklung der Mikroprozessoren und die damit einhergehende Massentauglichkeit der modernen Kommunikationsmedien haben dazu geführt, dass Individuen Gespräche vermehrt kulturübergreifend - und über Ländergrenzen hinweg - über das Internet führen können. Als moderne Kommunikationsform etabliert sich seit einigen Jahren immer weiter die Videokonferenz. Ihr didaktisches Potenzial wurde allerdings aus (fremd-)sprachwissenschaftlicher und (fremd-)sprachdidaktischer Sicht bislang verhältnismäßig wenig diskutiert.1 Wir wollen mit diesem Beitrag einen allgemeinen Überblick zur Forschungslage über den Nutzen von Videokonferenzen im Unterricht geben und der Frage nachgehen, ob Videokonferenzsoftware und Kontaktvermittlungsportale wie »Skype in the classroom« Möglichkeiten bieten, die kulturübergreifende Videokommunikation für den DaF-Bereich nutzbar zu machen.

Regionalität als Stärke? Eine Analyse von finnischen und niederländischen DaF-Lehrwerken
Authors: Maijala Minna , Tammenga-Helmantel Marjon
Published: May 2017

Die überregionalen bzw. globalen Lehrwerke werden für ein globales, nicht-spezifisches Publikum zusammengestellt und können aus diesem Grunde nicht immer die Wünsche und Bedürfnisse der Lernenden und Lehrenden vor Ort erfüllen. Dagegen liegt die Stärke der regionalen Sprachlehrwerke in den auf die dortige Zielgruppe zugeschnittenen Inhalten. Vor diesem Hintergrund wird im vorliegenden Beitrag der Fokus darauf gerichtet, inwiefern die von der Theorie festgehaltenen Vorteile in regionalen DaF-Lehrwerken in die Tat umgesetzt werden und ob die in der Praxis dieser Lehrwerke entwickelten Ideen in der Forschungsliteratur erfasst werden. Zuerst werden anhand von Forschungsliteratur globale und regionale Sprachlehrwerke verglichen. Im empirischen Teil des Beitrages werden alle zurzeit gängigen finnischen und niederländischen Deutschlehrwerke für den Anfängerunterricht in der Sekundarstufe I analysiert. Anhand von konkreten Beispielen aus den untersuchten DaF-Lehrwerken wird gezeigt, wie regionale DaF-Lehrwerke hinsichtlich der grammatikalischen und kulturspezifischen Inhalte an die Gegebenheiten vor Ort angepasst werden. Abschließend wird auf die Rolle des regionalen DaF-Lehrwerks als sprachlicher und kultureller Mediator vor Ort eingegangen.
Die Vermittlung der Artikelfunktionen in DaF-Lehrwerken. Wie berücksichtigen deutsche und japanische Anfängerlehrwerke die Zielgruppe der Lernenden mit artikelloser Erstsprache?
Authors: Lipsky Angela
Published: May 2017

Dieser Beitrag untersucht, inwieweit die Darstellungen der Artikelfunktionen in modernen DaF-Anfängerlehrwerken den besonderen Bedürfnissen von Lernenden mit artikelloser Erstsprache gerecht werden. Ausgewählt wurden drei nicht auf eine spezifische L1-Zielgruppe zugeschnittene deutsche Lehrwerke sowie drei für Lernende mit der artikellosen Erstsprache Japanisch konzipierte Lehrwerke aus Japan. Die Untersuchung wird zeigen, dass die einzelnen Lehrwerke sehr unterschiedliche Vermittlungsansätze wählen, aber nicht alle zu erwartenden Lernschwierigkeiten umfassend thematisieren können. Dabei soll auch auf die Vor- und Nachteile von einsprachigen und zweisprachigen Lehrwerken eingegangen werden.
Reasons for Volunteering in the Field of Civil Protection in Germany
Authors: Kehl Doris , Kietzmann Diana , Schmidt Silke
Published: May 2017

This study investigates how the demographic characteristics (i.e. gender, age, immigrant status) of people volunteering for civil protection organizations, as well as the type of organization, influence the volunteers’ motivation to provide this service. A sample of 3320 volunteers was drawn from the following non-profit civil protection organizations in Germany: a) Voluntary Fire Brigade, b) German Red Cross, and c) German Federal Agency for Technical Relief. Reasons for volunteering were assessed by the Scales of Attitude Structure of Volunteers. Correlation analyses, and ANOVAs were conducted. No effects of type of organization and immigrant status on reasons for volunteering were detected. Men’s and women’s reasons for doing voluntary service were equal, with one exception: self-experience motivation, i.e., the motivation to gain knowledge, skills etc., was higher among female volunteers. Age was negatively associated with social motivation, self-esteem, and career motivation. Our finding that gender and age affect volunteers’ motivation can be used to improve recruitment advertisements in the future: the various age groups can be targeted according to their specific motives for doing voluntary service, and the result that self-experience is more important to women than it is to men could also be explored to enhance the recruitment of women.
Design of Optimized Multiobjective Function for Bipedal Locomotion Based on Energy and Stability
Authors: Raj Manish , Nandi Gora C.
Published: May 2017

This paper presents a novel analytical method to develop the multiobjective function including energy and stability functions. The energy function has been developed by unique approach of orbital energy concept and the stability function obtained by modifying the pre-existing zero moment point (ZMP) trajectory. These functions are optimized using real coded genetic algorithm to produce an optimum set of walk parameters. The analytical results show that, when the energy function is optimized, the stability of the robot decreases. Similarly, if the stability function is optimized, the energy consumed by the robot increases. Thus, there is a clear trade-off between the stability and energy functions. Thus, we propose the multiobjective evolutionary algorithm to yield the optimum value of the walk parameters. The results are verified by Nao robot. This approach increases the energy efficiency of Nao robot by 67.05%, and stability increases by 75%. Furthermore, this method can be utilized on all ZMP classed bipeds.
Applications of design theory for the constructions of MDS matrices for lightweight cryptography
Authors: Gupta Kishan Chand , Pandey Sumit Kumar , Ray Indranil Ghosh
Published: May 2017

In this paper, we observe simple yet subtle interconnections among design theory, coding theory and cryptography.
Maximum distance separable (MDS) matrices have applications not only in coding theory but are also
of great importance in the design of block ciphers and hash functions. It is nontrivial
to find MDS matrices which could be used in lightweight cryptography. In the SAC 2004 paper [12], Junod and Vaudenay considered bi-regular matrices which are useful objects to build MDS matrices. Bi-regular matrices are those matrices all of whose entries are nonzero and all of whose

{2\times 2}

submatrices are nonsingular. Therefore MDS matrices are bi-regular matrices, but the converse is not true. They proposed the constructions of efficient MDS matrices by studying
the two major aspects of a

bi-regular matrix M, namely

In this paper, we explore the connection between the maximum number of ones in bi-regular matrices
and the incidence matrices of Balanced Incomplete Block Design (BIBD).
In this paper, tools are developed to compute

. Since, the number of ones in any

Published: May 2017

Background:

Hepatic involvement is a common feature in childhood mitochondrial disorders. Deoxyguanosine kinase (DGUOK) deficiency is one of the mitochondrial DNA depletion syndromes associated with hepatocerebral syndrome. Hepatic disease and neurologic dysfunction occurs within weeks after birth. Low birth weight is one of the common features. This study aims to describe the clinical and laboratory features of four infants carrying four different pathogenic variants in theDGUOKgene.

Case presentation:

Common clinical findings were progressive cholestatic liver failure, hypoglycemia, hypotonia and rotatory nystagmus in our DGUOK deficiency patients. Lactic acidosis, elevated serum tyrosine and ferritin levels were the striking laboratory features. Cholestasis, iron deposits, microvesicular steatosis and fibrosis were the histopathological findings seen in liver biopsies of two patients. All patients died with multi-organ failure between the ages of 42 days and 6 months.

Conclusions:

While neurologic findings may occur later in the course of the disease, elevated serum tyrosine levels may alert the physicians to a DGUOK deficiency in a baby with hepatopathy in the presence of the mentioned signs. Early diagnosis is important not only for genetic counseling but also for a possible liver transplantation.
Nonlinear Dynamics Analysis for the Taut Inclined Cable Excited by Deck Vibration
Authors: Qian C. Z. , Chen C. P.
Published: May 2017

A simple mechanical model is proposed to describe the dynamics system of the taut inclined cable excited by the deck vibration. Using Galerkin method, the dynamics system is simplified into a one-degree of freedom nonlinear system. Average method is used to obtain the average equations and bifurcation equation. Bifurcation maps are obtained and used to reveal the evolution mechanism of period-1 motion to period-2 motion. Several motion forms are discussed and evolution progress between different motions is studied. Several kinds of parametric resonance are revealed in various parameter regions. The conclusions indicate that the parametric resonance excited by the frequency ratio 3:2 is significant should be paid more attention.
The nitridoborate nitrides Mg3[BN2]N and Ca3[BN2]N – electronic structure and chemical bonding
Authors: Matar Samir F. , Al Alam Adel F. , Pöttgen Rainer
Published: May 2017

The nitridoborates Mg3[BN2]N (P63/mmc) and Ca3[BN2]N (P4/mmm) are electron-precise compounds with discrete linear [BN2]3− and isolated N3− anions. Electronic structure calculations reveal pronounced B–N bonding within the [BN2]3− units with more covalent Mg–N vs. Ca–N bonding. Total energy calculation for hexagonal normal-pressure Mg3[BN2]N, orthorhombic high-pressure Mg3[BN2]N and a hypothetical Ca3[BN2]N-type tetragonal Mg3[BN2]N modification revealed that the hexagonal modification is the ground state structure. The band structure for orthorhombic high-pressure Mg3[BN2]N indicates a substantial metallization (delocalization in the high-pressure regime). This peculiar result calls for a reinvestigation of high-pressure Mg3[BN2]N under different high-pressure high-temperature conditions along with physical property studies.
Vernetzung als regierungstechnologisches Rettungsprogramm?
Authors: Bode Ingo
Published: May 2017

Within the infrastructure of the modern welfare state, networking and collaboration across organizational and professional boundaries are far and wide considered as being deficient. At the same time, many experts refer to them as a silver bullet for overcoming institutional fragmentation and recent movements towards exacerbated social disintegration, even as governments tend to enforce collaboration formally. Using the example of child protection in Germany, this article draws on a mix of theories of government technologies in order to elucidate reasons for problems with actual collaborative arrangements in the social welfare sector, suggesting that, due to certain bottom-up dynamics, enforced networking in this sector is unlikely to be achieved by the policies under study. The analysis is based on evidence from case studies in five local settings, illustrating how major professional groups and organizations are dealing with evolving regulation and related challenges.
Beschäftigungsorientierte Beratung im Spannungsfeld von Bürokratie und Professionalität
Authors: Bender Gerd , Brandl Sebastian
Published: May 2017

Employment counselors are street-level bureaucrats; they do not simply execute government’s social policy, but have considerable room for discretionary decision-making. The article examines, on the one hand, whether the organizational conditions of their work make it easier or more difficult to act professionally, that is, to link current findings with knowledge acquired through training and work experience and thus develop action strategies that suit best a client’s individual situation – and to pursue them together with him or her. For only the orientation on professional counseling standards seems to safeguard against street-level activation policy that is based on coercion rather than on challenge. On the other hand, we discuss problems of recognizing the work of these specialists in a controlling and control system which is essentially based on outcome-based performance indicators.

Por lo tanto se mencionarán los puntos que permitan vislumbrar los requerimientos básicos que ayuden a las bibliotecas a tener, de manera clara, las normas sobre seguridad y salud que aseguren la estancia segura del personal y de los usuarios.
10-year trends of educational differences in long sickness absence due to mental disorders
Authors: Sumanen Hilla , Pietiläinen Olli , Lahelma Eero , Rahkonen Ossi
Published: May 2017

Objectives

Mental disorders are a key cause of sickness absence (SA) and challenge prolonging working careers. Thus, evidence on the development of SA trends is needed. In this study, educational differences in long SAs due to mental disorders were examined in two age groups among employees of the City of Helsinki from 2004 to 2013.

Methods

All permanently and temporarily employed staff aged 18-34 and 35-49 were included in the analyses (n=~27800 per year). SA spells of ≥14 days due to mental disorders were examined annually. Education was classified to higher and lower levels. Joinpoint regression was used to identify major turning points in SA trends.

Results

Joinpoint regression models showed that lower educated groups had more long SAs spells due to mental disorders than those groups with higher education. SA trends decreased during the study period in all studied age and educational groups. Lower educated age groups had similar SA trends. Younger employees with higher education had the fewest SAs.

Conclusions

A clear educational gradient was found in long SAs due to mental disorders during the study period. SA trends decreased from 2004 to 2013.

Resumo Este artigo teve como intuito realizar uma análise do comportamento espacial da pobreza no estado da Bahia nos anos 2000 e 2010, a partir do cálculo do Índice Municipal de Pobreza (IMP), colaborando com as análises da pobreza já realizadas para o estado. O índice permitiu a criação de rankings municipais de pobreza, que em comparação com o ranking do Índice de Desenvolvimento Humano Municipal (IDHM), nos mesmos períodos em análise, mostraram-se eficientes para mensuração da pobreza espacial na região. Com isso, encontraram-se evidências de um padrão de espacialização, bem como a existência de clusters de pobreza regional. Para este estudo foram utilizadas, além da renda, outras variáveis como educação, habitação e saúde, o que caracteriza o trabalho como multidimensional.
Serviço de Acolhimento Institucional para Crianças e Adolescentes: feedback effects, inflexões e desafios atuais
Authors: Miranda Geralda Luiza de
Published: May 2017

Resumo O objetivo do estudo é investigar, da perspectiva do institucionalismo histórico, a evolução histórica e a configuração atual do Serviço de Acolhimento Institucional para Crianças e Adolescentes em situação de risco. Argumenta-se que decisões prévias, por favorecerem o desenvolvimento de certas capacidades estatais em detrimento de outras, influenciam decisões correntes, explicando a dificuldade de mudança no curso das políticas. A análise mostra que escolhas feitas na Era Vargas prejudicaram a implementação de inovações do Código de Menores de 1979 e do Estatuto da Criança e do Adolescente (ECA), de 1990, até meados da década de 2000, quando a burocracia estatal na área da assistência foi fortalecida. A empiria utilizada são os dados do Censo Suas 2014 e as normativas que têm estruturado, desde o início do século XX, as políticas de assistência social e de atenção à criança e ao adolescente.
Linhas de pobreza no Plano Brasil Sem Miséria: análise crítica e proposta de alternativas para a medição da pobreza conforme metodologia de Sonia Rocha
Authors: Tronco Giordano Benites , Ramos Marília Patta
Published: May 2017

Resumo O presente trabalho critica a metodologia de medição da pobreza empregada pelo governo federal no âmbito do Plano Brasil Sem Miséria. Foi efetuada uma comparação, via compilação e análise descritiva de dados secundários da PNAD, entre essa metodologia e aquela utilizada pela economista Sonia Rocha, a qual estabelece linhas de pobreza regionalizadas e indexadas aos valores de cestas de consumo observadas nas diferentes regiões do país. Os resultados das duas medições foram comparados, mostrando que as linhas do PBSM são incapazes de captar 12,9 milhões de brasileiros que vivem em situação de pobreza. Como conclusão do artigo, são sugeridas, para o aperfeiçoamento da medição do governo, a regionalização das linhas e sua indexação ao preço de cestas de consumo regionais.

RESUMO Objetivo Este estudo objetivou investigar a associação entre problemas de comportamento e excesso de peso (sobrepeso e obesidade) em pré-escolares de uma coorte de nascimentos do sul do Brasil, acompanhados do nascimento aos 4 anos de idade. Métodos No acompanhamento dos quatro anos foram realizadas entrevistas domiciliares com as mães das crianças, tendo sido coletadas informações sobre a saúde e o desenvolvimento infantil, além de ser aplicado o Child Behavior Checklist 4-18/CBCL. Resultados Cerca de 15% dos meninos e 12% das meninas de 4 anos apresentaram excesso de peso, e a associação entre problemas de comportamento e o excesso de peso nessa idade se deu apenas em problemas de ansiedade-depressão, nas meninas (OR: 3,79 [IC95%: 1,60-8,97]; p = 0,002). Conclusões Meninas em idade pré-escolar com excesso de peso apresentaram mais problemas de ansiedade-depressão do que as com peso adequado da mesma idade. Essa informação é de extrema relevância, visto que os anos pré-escolares são ideais para se investir em prevenção, tanto dos problemas de comportamento, como do excesso de peso, possibilitando introduzir comportamentos/hábitos mais saudáveis e diminuir, assim, as consequências negativas que ambos acarretam à vida das crianças.

The strangest of all encounters: racial and ethnic discrimination in US health care
Authors: James Sherman A.
Published: May 2017

Abstract: In 2003, a Committee of the Institute of Medicine of the National Academy of Sciences summarized hundreds of studies documenting that US racial minorities, especially African Americans, receive poorer quality health care for a wide variety of conditions than their White counterparts. These racial differences in health care persist after controlling for sociodemographic factors and patients’ ability to pay for care. The Committee concluded that physicians’ unconscious negative stereotypes of African Americans, and perhaps other people of color, likely contribute to these health care disparities. This paper selectively reviews studies published after 2003 on the likely contribution of physicians’ unconscious bias to US health care disparities. All studies used the Implicit Association Test which quantifies the relative speed with which individuals associate positive attributes like “intelligent” with Whites compared to Blacks or Latino/as. In addition to assessing physicians’ unconscious attitudes toward patients, some studies focused on the behavioral and affective dimensions of doctor-patient communication, such as physicians’ “verbal dominance” and whether patients felt respected. Studies reviewed found a “pro-white” unconscious bias in physicians’ attitudes toward and interactions with patients, though some evidence suggests that Black and female physicians may be less prone to such bias. Limited social contact between White physicians and racial/ethnic minorities outside of medical settings, plus severe time pressures physicians often face during encounters with patients who have complex health problems could heighten their susceptibility to unconscious bias.
O pensamento político dos filósofos milésimos
Authors: Tierno Patricio
Published: May 2017

Resumo Este artigo pretende examinar o vocabulário político do pensamento milésio, movimento conformado por Thales, Anaximandro e Anaxímenes, autores de uma iniciativa intelectual que se desenvolveu nas circunstâncias históricas imperantes em Jônia durante o século VI a.C. No âmbito da pólis arcaica, esses pensadores formularam uma filosofia da natureza que, em diálogo e tensão com a mitologia tradicional e a religião antropomórfica, estabeleceu as bases de uma racionalidade filosófica e política concreta, a qual se manifestou numa linguagem conceitual e expressou a experiência singular da cidade grega antiga e as condições de sua evolução social transformadora.

Abstract The aim of this study was to evaluate the association between depressive symptoms and root caries among independent-living older persons. All community-dwelling older adults (not hospitalized and not bedridden) living in Carlos Barbosa, RS, Brazil, were invited to participate, and 785 completed the study protocol (standardized questionnaire assessing socio-demographic information and health behavior, Geriatric Depression Scale [GDS] - brief version, and oral examination [DMFT-Root index, Visible Plaque Index and stimulated salivary flow]). Out of them, 390 participants with at least one natural tooth were included in the present analysis. The outcome of interest was the ratio between the number of decayed roots and the number of roots at risk. The association between independent variables (depression and socioeconomic aspects) and the outcome was assessed using negative binomial regression models. Results: The final, fully adjusted model revealed that age (β=0.03, p=0.001), female sex (β=-0.23, p=0.08), living in a rural area (β=0.25, p=0.008), tooth brushing frequency (β=0.43, p=0.025) and stimulated salivary flow (β=-0.012, p<0.0001) were significantly associated with the presence of root caries. In addition, the interaction between male sex and the presence of depression symptoms (β=-0.99, p=0.012) was also independently and significantly associated with root caries. The interaction between male sex and depression symptoms was associated with root caries, suggesting that psychological mechanisms may be involved indirectly in the development of root caries in older adults.

Abstract Teratomas are tumors composed by tissues derived from the three germ cell layers, and they are relatively uncommon in head and neck. The term epignathus has been applied to teratomas from the oropharynx. This paper reports the case of a giant epignathus teratoma discovered at birth, which was successfully managed and followed up for 7 years. A newborn boy presented a polypoid tumor mass exteriorizing through the mouth over a length of 9 cm, with some surface areas resembling skin and others exhibiting hair. Computed tomography showed that the mass arose deep from the left hemiface. Alpha-fetoprotein (AFP) levels were high (316,000 ng/mL). Surgery was performed and microscopic analysis confirmed the diagnosis of mature teratoma. Because of residual tumor and high AFP levels, the patient was submitted to chemotherapy, resulting in complete regression of the lesion and normalization of AFP levels. Surgical repair of a cleft palate was performed at 5 years of age. At 7 years of age, the patient was in good general health and showed no clinical signs of recurrence. Although epignathus is a rare condition, it should be diagnosed in the fetus as early as possible. Prenatal care provides unquestionable benefits, providing the early diagnosis of anomalies that can jeopardize the life of the fetus and contributing to the indication of cases that require treatment before birth.

Resumo A língua é considerada um órgão-chave para os morcegos, pois os caracteres especializados são utilizados para fins taxonômicos e sistemáticos, estudos cladísticos e elucidação dos padrões dos hábitos alimentares. Objetivou-se caracterizar morfologicamente a língua das espécies Artibeus lituratus, Artibeus planirostris, Artibeus obscurus e Dermanura cinerea e relatar a primeira evidência de melanina no epitélio lingual de morcegos. Foram utilizados 20 exemplares coletados nos municípios de Vitória de Santo Antão e Sirinhaém, em Pernambuco. As línguas foram extraídas e submetidas a técnicas histológicas de rotina, coradas com hematoxilina e eosina (HE) e Fontana-Masson. Nas quatro espécies, foi observado o epitélio estratificado pavimentoso queratinizado, porém com presença de grânulos de melanina na camada basal somente nas espécies A. lituratus, A. planirostris e A. obscurus, evidenciados por meio da técnica de coloração por Fontana-Masson. A melanina encontrada na língua dessas espécies caracteriza-se como o primeiro registro para a ordem Chiroptera e pode estar relacionada à assepsia oral e/ou à inibição de substâncias tóxicas presentes em vegetais. Portanto, há necessidade de novos estudos, visando aprimorar o conhecimento acerca da função do pigmento nesse órgão.

Resumo Objetivou-se com este trabalho avaliar o efeito de diferentes frequências de desfolhação em períodos fixos sob as características estruturais e produtivas do dossel de capim-Tanzânia (Panicum maximum Jacq) em condições climáticas Am no ano de 2014. O delineamento experimental foi em blocos casualizados com seis tratamentos correspondentes a seis frequências de desfolhação (14; 21; 28; 35; 42 e 49 dias) e cinco repetições e os dados foram submetidos a análise de regressão. A interceptação luminosa (IL) aumentou (P<0,05) de maneira assintótica com o aumento dos períodos de descanso, no qual a máxima interceptação de luz foi de 98% e ocorreu aos 42 dias de rebrotação. O índice de área foliar (IAF) e o acúmulo de matéria seca, aumentaram (P<0,05) linearmente variando de 3,6 a 7,1 e de 880,3 a 4051,7 kg.ha-1 de matéria seca de forragem, nas frequências de 14 a 49 dias, respectivamente. A altura variou de 44 a 119 cm nas frequências de 14 a 49 dias, respectivamente. A frequência de desfolhação que representa uma IL de 95% está relacionada ao período de descanso de 29 dias, em que o dossel de capim-Tanzânia apresentou altura em torno de 63 cm, IAF crítico de 5,1 e acúmulo de matéria seca de forragem de 2.160 kg.ha-1.
