Published: June 2016

AbstractDelayed planting is recommended to reduce damage from sunflower insect pests in the United States, including the sunflower moth, Homoeosoma electellum (Hulst) and banded sunflower moth, Cochylis hospes Walsingham. However, in some locations, planting earlier or growing later-maturing hybrids could improve yield or oil content of sunflowers which would partially offset any added costs from insect pests or their management. Because the abundance and distribution of some sunflower insects have changed since recommendations for delayed planting were developed, experimental plots were grown in 2012 and 2013 at sites in North Dakota, Nebraska, Iowa, and Illinois. Sunflowers were planted two to four weeks earlier than normal, including hybrids that flower two to three weeks later than elite commercial hybrids. The sum of seed damaged by sunflower moth, banded sunflower moth, and red sunflower seed weevil, Smicronyx fulvus LeConte, (i. e., total percentage) was influenced by location, but not the relative maturity of tested entries. However, when damage attributed solely to the red sunflower seed weevil was analyzed, more damaged seed were found for late-maturing entries in North Dakota and Nebraska. In addition to the trial data, current pest populations are lower than when delayed planting was first recommended and insecticide use during sunflower bloom is both common and effective. Together, these observations suggest factoring insect pests into planting time decisions may be unnecessary, except for areas with a history of problems with severe pests that cannot be managed using insecticides (e. g., sunflower midge, Contarinia schulzi Gagné).

Abstract
In this work, a pleonastic compound, a compound with a composition between hercynite and spinel sensu stricto FeAl2O4–MgAl2O4, was synthesized by a non-conventional method of arc-plasma synthesis (APS). The structure of the obtained spinel compound was characterized by means of X-ray diffraction and Mössbauer effect measurements. The microstructure was observed by applying scanning electron microscope (SEM)/energy dispersive spectrometer (EDS) method. It was found that the arc-plasma synthesized material was characterized by a monophasic character, a low-inversion parameter and a compact microstructure.
Perceptions and use of sources of health knowledge by young adolescents

Published: June 2016

Abstract

Background:
Understanding how adolescents acquire health knowledge and where they currently seek answers to health-related questions may facilitate the development of interventions that will be both engaging and effective, and may help to improve health over the short- and long-term.

Objective:
The present study sought to investigate the perception and use of sources of health knowledge by young adolescents as stratified by gender.

Methods:
Thirty 50-min long focus groups were conducted with 143 participants. Focus group questions were built around the following three main categories: sources of knowledge, including preferred sources, sources accessed for general health, and sources accessed for personal/sensitive health; health information and behaviour change, including characteristics of health knowledge presentation that have influenced behaviour change; and learning preferences to promote behaviour change. Content analysis of focus group transcripts was performed.

Results:
The use of sources of health knowledge was similar between genders, with some differences noted between sources accessed for general as compared to personal health questions. As well, motivation appeared to be the primary influence of health behaviour change, with knowledge being reported as both as positive and neutral influence, most notably in the areas of diet and exercise. Lastly, adolescents reported several characteristics of health knowledge presentation that they felt would motivate positive behaviour change, including engaging and participatory activities.

Conclusion:
These results should be considered in the development of interventions to improve health-related behaviour in adolescents, although future research to quantify the use of sources of health knowledge by this population is recommended.
Clustering of behavioural risk factors for non-communicable diseases (NCDs) among rural-based adolescents in south-west Nigeria

Published: June 2016

Abstract

Background:
Non-communicable diseases (NCDs) have become the leading cause of deaths globally and the key associated risk factors – alcohol abuse, physical inactivity, cigarette smoking and poor dietary patterns – are often initiated in adolescence. Co-existence of these risk factors further increase the risk for NCDs. Yet, very little is known about the pattern of co-occurrence of behavioural risk factors for NCDs among Nigerian adolescents, especially those in rural areas. This study aimed to assess the prevalence and determinants of clustering patterns of behavioural risk factors for NCDs among in-school adolescents in rural areas of Osun State, Nigeria.

Methods:
This cross-sectional study involved 476 adolescents recruited through multi-stage sampling across Osun State. Data were collected through a facilitated self-administered questionnaire with questions adapted from the Global School-Based Health Survey (GSHS) instrument. Data were analysed using Stata, with binary logistic regression used to identify determinants.

Results:
The mean age of the respondents was 14.7±2.0 years and females constituted 50.2% of them. Among the respondents, 36.1% had reported consuming alcoholic drinks but no one met the criteria for harmful alcohol use, while 8.8% had ever smoked cigarettes and only one respondent (0.2%) was a current smoker. The prevalence of poor diet (89.5%) and physical inactivity (85.9%) was, however, high. Poor diet and physical inactivity co-occurred in 369 (77.5%) respondents, while one respondent (0.2%) had three risk factors (poor diet, physical inactivity and current smoking). Being in a senior secondary school class (odds ratio, OR=1.6; 95% confidence interval, C.I.=1.04–2.39) and living with parents (OR=0.53; 0.33–0.90) were significantly associated with clustering of NCD behavioural risk factors.

Conclusion:
The prevalence of clustering of modifiable risk factors for NCDs was high among rural-based in-school adolescents in south-west Nigeria, and there is a need to mount effective interventions. Findings from this study have the potential to inform effective school-based NCD control programmes.

Published: June 2016

Abstract
This study investigated students’ evaluations of a positive youth development program entitled Project P.A.T.H.S. (Positive Adolescent Training through Holistic Social program) in Hong Kong. The participants were 19,790 Secondary 1, 2 and 3 students who joined this program at the extension phase of the project. They were required to complete a subjective outcome evaluation form to indicate their perceptions of the program content, instructors, and effectiveness. Results showed that the students evaluated this program positively. Amongst the students in the three grades, Secondary 1 students evaluated the program most favorably whereas Secondary 3 students had the relatively least favorable evaluation. In addition, the program content and instructors accounted for approximately 35% of the variance in program effectiveness. The findings generally imply the successful implementation of this program in the community-based phase.

Published: June 2016

AbstractThis study evaluated a university general education subject on leadership and intrapersonal development (“Tomorrow’s Leaders”, TL) offered at The Hong Kong Polytechnic University (PolyU) based on an online survey using the Student Feedback Questionnaire (SFQ). At the end of the first semester of the 2013/2014 academic year, 725 Year-1 students completed the online questionnaire. Results showed that the students generally had positive ratings on both the subject attributes and the qualities of teachers. The majority of the participants perceived the subject as beneficial to their holistic development and leadership competencies. Students from the Faculty of Health and Social Sciences (FHSS) and the Faculty of Applied Science and Textiles (FAST) had more favorable evaluation of the subject than students from the Faculty of Construction and Environment (FCE). Students’ perceived benefit of the subject was significantly predicted by the subject attributes and teacher attributes. Implications of the findings are discussed.

Published: June 2016

Abstract
An isothermal plug flow reactor model with extended Fick diffusion model for transport through the porous membrane is utilized for simulation of ethylene oxide formation in a packed bed membrane reactor (PBMR). The model was verified and validated using published experimental data from an existing lab-scale unit. Sensitivity analysis was performed to determine robustness of the model. A conceptual approach on operation and design stage multi-objective optimization study is discussed. Real-coded NSGA-II is used and effect of its parameters on optimization of reactor performance is also studied. The results of three two-objective operation-stage (with 4 decision variables) and one two-objective design-stage (with 6 decision variables) optimization case studies are presented. Good convergence to a Pareto optimal solution is achieved for all cases. Significant improvement over current experimental operation is observed in terms of increase in conversion of ethylene, selectivity to ethylene oxide and ethylene oxide product flow rate.
The politics of language contact in northwestern California: Maintaining diversity in the face of cultural convergence
Authors: O’Neill Sean 
Published: June 2016

AbstractThis article examines the language ideologies and socio-political realities associated with the highly localized oral traditions of northwestern California, including both stories and songs, which are both connected in profoundly indexical ways to the distinctiveness of the languages. My findings suggest that the principle oflinguistic relativity, whereby speakers of contrasting languages subscribe to different worldviews, often emerges from conscious choices of interpretation among community members, who actively strive to set their languages and worldviews apart from those of neighboring societies – in association with a pervasive ideology of localism. Today, as the languages undergo revitalization, this long-standing concern with local difference is receiving renewed attention in the context of the tribal language programs where speakers are also striving to keep their languages, stories, songs, and worldviews distinct – both from the neighboring tribes as well as the English-speaking world. Today, as in the past, the distinctive languages continue to play an important role in the maintenance of identity, setting the communities apart in publicly accentuated ways and instilling language learners with a sense of pride in the uniqueness of their own traditions.
Communicative strategies across Quechua languages
Authors: Luykx Aurolyn , García Rivera Fernando , Julca Guerrero Félix 
Published: June 2016

AbstractThough usually referred to as “the Quechua language”, Quechua is actually a diverse language family extending from Colombia to northern Argentina. Quechua languages are not all mutually intelligible, but speakers are generally unaware of that fact, since they use it mostly in local, communitarian settings. This study examines the evolving speech behavior and meta-linguistic discourse of an international group of Quechua speakers, most of whom were encountering different varieties of Quechua for the first time as participants in a two-year graduate program in bilingual-intercultural education. Over the course of the program, students developed several strategies to facilitate communication across their different Quechua varieties. We examine those strategies and their implications for language planning, language education, and the emergence of a broader pan-Quechua identity.

The Enterprising Self and Prejudices toward Unemployed Persons
Authors: Groß Eva 
Published: June 2016

Abstract:
This research tries to build bridges between sociological and social psychological theoretical ideas for the study of social inequality in neoliberal societies. It adds to research on social inequality by examining amplifiers of prejudices toward unemployed persons. A conceptual model has been developed which draws upon social dominance theory and governmentality studies. The empirical analyses guided by this model assess the mediating effects of the enterprising self – a newly developed attitude measure based on sociological analyses of contemporary self-help literature – and the Protestant Work Ethic in the relationship between social dominance orientation and prejudices toward unemployed persons, both depending on social status. Conditional process models reveal the phenomenon of ideological asymmetry relevant for the enterprising self, indicating that this neoliberal guiding principle serves as a dominant driving force in reproducing social inequality through mechanisms at the intergroup-level.

Published: June 2016

AbstractThe weak intermolecular noncovalent interactions in the solvatecis-[PtCl2(C2H5CN)2]·CHCl3were studied by XRD and DFT methods. Special attention was paid to a chloroform molecule as a potential donor of both hydrogen and halogen bonds. On the one hand, the H atom of chloroform links two Cl atoms ofcis-[PtCl2(C2H5CN)2] (Hchloroform–Clcomplex(2.660 Å, 2.811 Å)), and on the other side, the weak Clchloroform–Clcomplex(3.247 and 3.497 Å) interactions were found. According to DFT calculation, only the Hchloroform–Clcomplex(2.660 and 2.811 Å) and Clchloroform–Clcomplex(3.247 Å) interactions can be classified as weak noncovalent bonds, whereas the contacts Clchloroform–Cnitrile(3.391 Å) and Clchloroform–Clcomplex(3.497 Å) are due to the crystal packing effect.

Published: June 2016

Abstract
A selected set of N1-(4-chloro-9-ethylcarbazol-3-yl)amidrazones (7a–n) has been synthesized by reacting the respective hydrazonoyl chloride 5 derived from 3-amino-9-ethylcarbazole (3), with an appropriate sec-cyclic amine (6a–n) in ethanol in the presence of triethylamine. Unexpectedly, aromatic ring chlorination occurred at C-4 of 3 during its conversion to 6 as evidenced by analytical and spectral data and further confirmed by single crystal X-ray structure determination of the amidrazone 7n. Compounds 7a–n were tested for their in vitro antibacterial activity. Among the tested bacterial strains, methicillin-resistant Staphylococcus aureus was the most susceptible to 7f and Bacillus cereus to 7b both with a minimum inhibitory concentration value of 1.56 µg mL−1. Compounds 7c, 7f, and 7h could be useful as lead structures for further development of new antibacterial agents against Gram-positive and Gram-negative pathogens.

Flexibilización laboral en el sector de la salud: aproximación desde la gestión de la seguridad y la salud en el trabajo
Authors: Rodríguez Rojas Yuber Liliana , Molano Velandia Jorge Hernando 
Published: June 2016

<p>El presente artículo busca describir los efectos y exigencias de la flexibilidad laboral, especialmente en el sector de la salud, y las implicaciones que tiene para la gestión de la salud y la seguridad laboral. Para lograr este objetivo, se realiza una revisión temática que evidencia que la salud es uno de los sectores más impactados por dicho fenómeno. Lo anterior se ve reflejado en la inestabilidad laboral de los trabajadores, la cual es generada por el cambio en las modalidades de contratación; la susceptibilidad de despido y de rotación; en el descentramiento del trabajo; la segmentación de la mano de obra y la reducción de la libertad sindical. Al ser la gestión de la salud y seguridad en el trabajo un proceso sistemático y organizado, orientado a la protección de la salud y al fomento de la seguridad de la población laboral, permite la incorporación de componentes que llevan a complementar la gestión de las organizaciones en aspectos que no han sido tradicionalmente tenidos en cuenta en un nivel suficiente para lograr beneficios organizacionales y de las personas. </p>

<p>La seguridad del paciente ha cobrado gran importancia durante los últimos años, en razón a que los daños causados durante la prestación de servicios asistenciales<br />impactan la calidad de vida de las personas y generan sobrecostos en los sistemas de salud. Estos daños pueden ser prevenidos dependiendo de la importancia que<br />las instituciones y sus profesionales den a la gestión del riesgo. El reporte de los eventos adversos en áreas ambulatorias como la odontología debe cobrar mayor<br />importancia, ya que el gran número de pacientes y la extensa duración de los tratamientos exponen a los pacientes a la materialización de un riesgo, representado en un evento adverso. El presente estudio determina los eventos adversos en ortodoncia desde la perspectiva de la norma técnica ISO 31000 (ICONTEC, 2011) y proporciona un listado que facilita su identificación y sirve para estimular el reporte y promover la gestión del riesgo durante el ratamiento de ortodoncia.</p><p>Se utilizó la técnica de grupos focales, con 4 grupos de expertos.
