Suicide-related Internet use among university students
Authors: Voros V. , Osvath P. , Szabo Z. , Nagy Z. , Fekete S. 
Published: June 2017

IntroductionNowadays, mobile and Internet communication is widely used and has a special role in mental health prevention. Besides, websites targeting suicide prevention, pro-suicide contents (methods for suicide, suicide pacts) are also easily available, which may increase the risk for suicide in vulnerable people.AimsOur aim was to assess the relation between Internet use and suicidal behaviour among university students and also to assess online activity regarding suicidal contents and help-seeking behaviour.MethodsSelf-administered questionnaires were completed by university students.ResultsMost of the 101 students who completed the survey use the Internet 3 hours or more a day. They are facing suicidal contents numerous times. Professional websites providing information and the common popular sites were mainly visited, sites providing help were less screened (10%). More than quarter of the students felt discomfort when looking at sites dealing with suicide. Almost one-third of the subjects had suicidal thoughts during their lives and 15% already planned suicide. In case of suicidal thoughts, subjects would seek help mainly from friends and family, but online help-seeking was not preferred.ConclusionsDespite of the extensive Internet use, students rarely seek help for emotional problems on the Internet. Development of websites controlled by professionals is essential, especially for those who would not benefit from traditional psychological/psychiatric care. Future research is needed regarding the characteristics of Internet use and the potentials and limits of help-seeking via the Internet in order to prevent people from pro-suicide websites and to improve professional websites.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Published: June 2017

Background Methionine synthase deficiency is a rare inborn error of intracellular cobalamin metabolism caused by mutations in the MTR (5-methyltetrahydrofolate-homocysteine S-methyltransferase) gene, resulting in megaloblastic anemia and neurologic symptoms.
Methods and Results We describe for the first time a homozygous MTR gene c.3518C > T (p.P1173L) mutation in a patient with severe megaloblastic anemia, developmental delay, and drug-resistant seizures associated with hyperhomocysteinemia and hypomethioninemia. Methionine synthase activity was only 9% of the reference value, and MTR protein expression was decreased in the fibroblasts of the patient. The clinical features of our patient are similar to previously published patients with the complementation type G disorder of methionine synthase deficiency with the exception of drug-resistant seizures. However, intramuscular injections of hydroxocobalamin (OHCbl) in conjunction with betaine and folic acid provided verified clinical and electrophysiological treatment response.
Conclusion This study emphasizes the importance of early diagnosis of patients having neurologic symptoms due to methionine synthase deficiency where early treatment has significant effects on the clinical outcome of the patients. Elevated level of plasma homocysteine together with low methionine in plasma amino acid analysis should raise a suspicion of remethylation disorder.
Jugendliche und junge Erwachsene mit Adipositas: Wie sollte in ihren Augen „die perfekte Therapie“ aussehen?
Authors: Warschburger Petra 
Published: June 2017

Zusammenfassung
Hauptziel Adipositas ist eine der Hauptindikationen in der Kinder- und Jugend-Rehabilitation. Für ältere Jugendliche und junge Erwachsene fehlen altersspezifische Therapieangebote fast vollständig. Ziel war es die Wünsche bezüglich der Inhalte und Methoden einer „perfekten Therapie“ im Rahmen eines Rehabilitationsaufenthalts zu untersuchen.
Methode Im Rahmen der YOUTH-Studie wurden 147 adipöse Jugendliche und junge Erwachsene beiderlei Geschlechts (zwischen 15 und 21 Jahren) mithilfe eines standardisierten Fragebogens befragt.
Ergebnis Insgesamt zeigten sich relativ wenige alters- und geschlechtsspezifische Unterschiede. Interdisziplinär geleitete, koedukative Gruppen mit Elterneinbindung wurden gewünscht. Wichtige Themen waren gesunde Ernährung sowie psychosoziale Aspekte. Auch der Prävention von Rückfällen wurde eine hohe Relevanz zugeschrieben.
Schlussfolgerung Psychosoziale Aspekte und die Vorbereitung auf mögliche Rückfallsituationen sollten integraler Bestandteil der Therapie sein.

Up-to-Date on Preventive Care Services Under Affordable Care Act
Authors: Hong Young-Rock , Jo Ara , Mainous Arch G. 
Published: June 2017

Background:
The utilization of preventive care services has been less than optimal. As part of an effort to address this, the Affordable Care Act (ACA) mandated that private health insurance plans cover evidence-based preventive services.

Objectives:
To evaluate whether the provisions of ACA have increased being up-to-date on recommended preventive care services among privately insured individuals aged 18–64.

Research Design:
Multivariate linear regression models were used to examine trends in prevalence of being up-to-date on selected preventive services, diagnosis of health conditions, and health expenditures between pre-ACA (2007–2010) and post-ACA (2011–2014). Adjusted difference-in-difference analyses were used to estimate changes in those outcomes in the privately insured that differed from changes in the uninsured (control group).

Results:
After the passage of ACA, up-to-date rates of routine checkup (2.7%; 95% confidence interval, 0.8%–4.7%; P=0.007) and flu vaccination (5.9%; 95% confidence interval, 4.2%–7.6%; P<0.001) increased among those with private insurance, as compared with the control group. Changes in blood pressure check, cholesterol check and cancer screening (pap smear test, mammography, and colorectal cancer screening) were not associated with the ACA. Prevalence in diagnosis of health conditions remained constant. Slower uptrends in adjusted total health care expenditures and downtrends in adjusted out-of-pocket costs were observed during the study period.

Conclusions:
The provisions of the ACA have resulted in trivial increases in being up-to-date on selected preventive care services. Additional efforts may be required to take full advantage of the elimination of cost-sharing under the ACA.
ICD Social Codes

Published: June 2017

Background:
Social determinants of health (SDH) data collected in health care settings could have important applications for clinical decision-making, population health strategies, and the design of performance-based incentives and penalties. One source for cataloging SDH data is the International Statistical Classification of Diseases and Related Health Problems (ICD).

Objective:
To explore how SDH are captured with ICD Ninth revision SDH V codes in a national inpatient discharge database.

Materials and Methods:
Data come from the 2013 Healthcare Cost and Utilization Project (HCUP) National Inpatient Sample, a national stratified sample of discharges from 4363 hospitals from 44 US states. We estimate the rate of ICD-9 SDH V code utilization overall and by patient demographics and payer categories. We additionally estimate the rate of SDH V code utilization for: (a) the 5 most common reasons for hospitalization; and (b) the 5 conditions with the highest rates of SDH V code utilization.

Results:
Fewer than 2% of overall discharges in the National Inpatient Sample were assigned an SDH V code. There were statistically significant differences in the rate of overall SDH V code utilization by age categories, race/ethnicity, sex, and payer (all P<0.001). Nevertheless, SDH V codes were assigned to <7% of discharges in any demographic or payer subgroup. SDH V code utilization was highest for major diagnostic categories related to mental health and alcohol/substance use-related discharges.

Conclusions:
SDH V codes are infrequently utilized in inpatient settings for discharges other than those related to mental health and alcohol/substance use. Utilization incentives will likely need to be developed to realize the potential benefits of cataloging SDH information.
Examining nonlinear relationships between quality management and financial performance
Authors: Roca-Puig Vicente , Escrig-Tena Ana B. 
Published: June 2017

Purpose
A thorough analysis of nonlinear relationships between quality management (QM) and organizational outcomes has largely been ignored in the current empirical QM literature, which can have profound theoretical and managerial implications. The existence of nonlinear relationships implies taking a contingent view in that QM practices are more effective depending on their level of implementation in an organization. The purpose of this paper is to focus on this possibility and undertake an in-depth study of the sparse nonlinear relationship suggested by the literature.

Design/methodology/approach
The authors introduce an empirical study carried out on a sample of 168 service firms belonging to sectors experienced in QM and, through polynomial regression analysis, identify the nature of the relationship between QM and financial performance (return on assets).

Findings
The results, by showing an S-shaped curve, support a nonlinear association between these two variables. The presence of this functional form provides a satisfactory solution to the growing debate among researchers who, from a linear perspective, defend the positive effects of QM on organizational outcomes, those who find no significant effect, and still others who claim that QM has a negative effect.

Originality/value
The results show that in organizations with a low level of QM implementation, managers should increase investment in QM, even though this increase will not be correspondingly beneficial in the same proportion. In contrast, in organizations with a high level of QM implementation, managers are advised to reflect on undertaking projects that represent an additional investment in QM, with the aim of finding their optimal level.
The episodic spiral model: a new approach to organizational processes
Authors: Boje David M. , Baca-Greif Heather , Intindola Melissa , Elias Steven 
Published: June 2017

PurposeThe purpose of this paper is to develop a new model for depicting organizational processes: the episodic spiral model (ESM).Design/methodology/approachOn the basis of a strong process view as the orienting paradigm, the authors demonstrate the need for the ESM by discussing the shortcomings of two specific spiral types in the organizational literature – the knowledge creation spiral and the efficacy spiral.FindingsA review of each spiral type through the lens of nonlinear assumptions reveals the treatment to date of organizational spirals as uni-directional and insufficient for understanding organizations. The authors propose that managers must undertake a paradigm shift in order to gain a greater awareness of both the environment in which they operate, as well as their process actions. To facilitate this shift, the ESM depicts choice points, chosen and rejected trajectories, and upward and downward environmental drafts, as well as a multi-dimensional environment, as a way of re-conceptualizing approaches to space, time, and change in organization studies.Originality/valueThe authors propose that the model provides a way for scholars to enhance the study of organizations by understanding that organizations exist in a more dynamic environment than previously studied; recognizing that the organization has a wider range of choices available, and acknowledging the long-lasting ramifications of both choices made and choices discarded; and obtaining a more comprehensive look at the way the organization moves through space and time at any given moment. Taken together, the authors hope that these contributions allow organizational scholars a new approach to theorizing, exploring, and writing about the organizations they study.
Sample size determination for a matched‐pairs study with incomplete data using exact approach
Authors: Shan Guogen , Bernick Charles , Banks Sarah 
Published: June 2017

This research was motivated by a clinical trial design for a cognitive study. The pilot study was a matched‐pairs design where some data are missing, specifically the missing data coming at the end of the study. Existing approaches to determine sample size are all based on asymptotic approaches (e.g., the generalized estimating equation (GEE) approach). When the sample size in a clinical trial is small to medium, these asymptotic approaches may not be appropriate for use due to the unsatisfactory Type I and II error rates. For this reason, we consider the exact unconditional approach to compute the sample size for a matched‐pairs study with incomplete data. Recommendations are made for each possible missingness pattern by comparing the exact sample sizes based on three commonly used test statistics, with the existing sample size calculation based on the GEE approach. An example from a real surgeon‐reviewers study is used to illustrate the application of the exact sample size calculation in study designs.

Sharp geometric requirements in the Wachspress interpolation error estimate
Authors: Monzón Gabriel 
Published: June 2017

AbstractGeometric conditions on general polygons are given in [9] in order to guarantee the error estimate for interpolants built from generalized barycentric coordinates, and the question about identifying sharp geometric restrictions in this setting is proposed. In this work, we address the question when the construction is made by using Wachspress coordinates. We basically show that the imposed conditionsbounded aspect ratio property(barp),maximum angle condition(MAC) andminimum edge length property(melp) are actually equivalent to (MAC, melp), and if any of these conditions is not satisfied, then there is no guarantee that the error estimate is valid. In this sense, (MAC) and (melp) can be regarded as sharp geometric requirements in the Wachspress interpolation error estimate.

Published: June 2017

Abstract
This study investigated the elastic elongation and elastic recovery of the elastic warp knittedfabric made of PET( polyethylene terephthalate) and PBT(polybutylene terephthalate) filament. Using 50/24F PET and 50D/24F PBT in two threadingbars, the tricot, locknit and satin warp knitted fabrics were produced on the E28 tricot warpknitting machine. The knitting parameters influencing the elastic elongation under 100N wereanalyzed in terms of fabric structure, yarn run-in speed and drawing density set on machine.Besides, dyeing temperature and heat setting temperature/time were also examined in order toretain proper elastic elongation and elastic recovery. The relationship between elastic elongationand knitting parameter and finishing parameter were analyzed. Finally, the elastic recovery ofPET/PBT warp knitted fabric was examined to demonstrate the elastic property of final finishedfabric. This study could help us to further exploit the use of PET/PBT warp knitted fabric in thedevelopment of elastic garment in future.
Interactions of Various types between Rock and Alkali-Activated Blast Furnace Slag
Authors: Mec Pavel , Gembalová Lucie 
Published: June 2017

Abstract
Alkali-activated binders (AAB) are very intensively studied materials nowadays. Because of possible usage as secondary raw materials, they can be environmentally efficient. Intensive research is focused especially on binder matrix, composition and its structure. For industrial usage, it is necessary to work with some aggregate for the preparation of mortars and concretes. Due to different structures of alkali-activated binders, the interaction with the aggregate will be different in comparison to an ordinary Portland cement binder. This paper deals with the study of interactions between several types of rocks used as aggregate and alkali-activated blast furnace slag. The research was focused especially on mechanical properties of prepared mortars.
Problems of 14–18 Years Old Youth and the Trends of Organisation of Prevention Activities: Lithuanian Case
Authors: Valantiejienė Sandra 
Published: June 2017

Abstract
The World Health Organization (since 1998) recognises that many modern diseases and disorders (including social problems) are caused by risky behaviour. Youth risky behaviour is generally defined as a behaviour that directly or indirectly threatens the young person’s well-being and health. This is usually understood as smoking, abuse of alcohol and psychoactive substances and early initiated and unprotected sexual relations. However, the risky behaviour also includes basic things such as the failure to comply with diet regimen, sedentary lifestyle, not wearing the safety belt in the car and failure to wear a helmet whilst cycling or rollerblading. Adolescence itself is a risky span of the human life, as it is associated with moving from childhood into the adult world and intensive search for the personal identity. To ensure a consistent development of personality, adolescent risky behaviour prevention include harmonisation of education processes to help teenagers to develop responsible behaviour skills by reducing the risk factors and increasing protective factors. The article aims to overview the factors that influence youth risky behaviour and the factors that determine the planning and organisation of preventive activities for the pupils in the higher classes of the schools of general education. The study was completed in the form of a questionnaire that was conducted in the schools of the Lithuanian Republic in 2016. The results of the study describe trends of the prevention policies applied in the system of education, considering the national context of the individual Member States of the European Union.
Geospatial Assessment of Forest Fragmentation and its Implications for Ecological Processes in Tropical Forests
Authors: Adepoju Kayode Adewale , Salami Ayobami T. 
Published: June 2017

AbstractThe study assessed the patterns of spatio-temporal configuration imposed on a forest landscape in Southwestern Nigeria due to fragmentation for the period 1986 – 2010 in order to understand the relationship between landscape patterns and the ecological processes influencing the distribution of species in tropical forest environment. Time-series Landsat TM and ETM satellite images and forest inventory data were pre-processed and classified into four landuse/landcover categories using maximum likelihood classification algorithm. Fragstats software was used for the computation of seven landscape and six class level metrics to provide indicators of fragmentation and landscape connectivity from the classified images.The result shows that although deforestation reduced between 2000 and 2010, fragmentation, however intensified during the 24 years period. Fragmentation was highest between 1991 and 2000, leading to significant landscape variability, alteration in the general biotic and abiotic conditions and exchange of material and energy. While it appears that overall forest area increased between 2000 and 2010, connectivity and biodiversity indicators declined the most during this period. The resulting scenario is that forest fragmentation, despite the control of deforestation in the last decade of this study have certainly not receded in the study area. This may continue to have subtle negative impact on exchange of material and energy in the ecosystem, contribute to increased depletion of vital forest resources and the disappearance of wildlife from previously known areas.

AbstractThe objective of this study was to investigate the effects of inoculum concentration, plant post-inoculation incubation temperature and exogenous hydrogen peroxide (H2O2) on the induction of the hypersensitive response (HR) inNicotiana tabacumagainstXanthomonas perforans. Inoculation of leaves withX. perforansat a concentration of 108CFU · ml−1and incubation of plants at 30°C resulted in the strongest HR elicitation. Furthermore, an exogenous supply of H2O2acceleratedX. perforans-induced HR, whereasin plantaH2O2removal by application of catalase led to a delay in HR development. Our data suggest that H2O2has an important role in HR ofN. tabacumagainstX. perforans.
Evaluación de la tutoría en los estudios d posgrado: construcción y validez de escalas
Authors: De la Cruz Flores G. , Abreu Hernández L. F. 
Published: June 2017

<p>El posgrado orientado a la formación de investigadores es una pieza angular en el desarrollo del conocimiento y las sociedades contemporáneas. Este nivel posee escasos instrumentos para evaluar la tutoría con énfasis en sus funciones y actividades. Dicha carencia puede explicarse en virtud de la falta de definiciones sobre el constructo denominado “tutoría en posgrado”. La tutoría en los estudios de posgrado se reconoce como un modelo de formativo personalizado que coadyuva al desarrollo de capacidades para la investigación, la práctica profesional y la incorporación a la docencia en la educación superior. No obstante este concepto debe ser ampliado para incluir a los aspectos relacionados con la socialización y la integración de los estudiantes a las comunidades epistémicas y profesionales. En el presente artículo se fortalecen estos atributos y se da cuenta del proceso de construcción y validación de once escalas de respuesta tipo Likert, que permiten valoran el desempeño de la tutoría en los estudios de posgrado. Las escalas fueron elaboradas con base en un modelo conceptual que integra tanto funciones formativas como las socializadoras así como aspectos interpersonales que promueven la interacción entre posgraduados y tutores. Cada escala presenta una consistencia interna aceptable. La validez de las mismas se obtuvo mediante análisis factoriales, cada escala explica más del 50% de la varianza.</p><div> </div>
