Authors: Deliönü Özcan , Garipağaoğlu Burçak Çağla 
Published: April 2015

<p>The purpose of this study is to determine the causes of job dissatisfaction among teachers in the field of vocational and technical education and suggest viable alternatives for the solution of this problem. The study was conducted with qualitative research techniques. The data was collected from a total of 44 participants via one-to-one interviews and focus group discussions. To obtain a better and more holistic picture of the factors leading to job dissatisfaction, participants were selected from vocational and technical schools located in various parts of İstanbul with high population of teachers and students. The results of the study demonstrate that the causes of job satisfaction are generally related with communication within the organization, working conditions, school administration and social reputation of teaching as a profession rather than the pay, job security, professional development and promotion opportunities. Moreover, it was understood that stress resulting from workplace conflicts, heavy workloads, vague job descriptions and unmet expectations are found to be closely related with job dissatisfaction among vocational and technical teachers. </p><p> </p><p><strong>Özet</strong></p><p class="Normal1">Bu araştırmanın amacı meslek liselerinde çalışan mesleki teknik öğretmenlerin iş doyumsuzluğuna ilişkin görüş ve düşüncelerini belirlemek, ve sorunun çözümü için uygun önerilerin geliştirilmesini sağlamaktır.

On the intersection of a Hermitian surface with an elliptic quadric
Authors: Cossidente Antonio , Pavese Francesco 
Published: April 2015

Abstract
We investigate the intersection between the generalized quadrangle arising from a Hermitian surface H(3, q2) and an elliptic quadric Q−(3, q2) of PG(3, q2). In odd characteristic we determine the possible intersection sizes between H(3, q2) and Q−(3, q2) under the hypothesis that they share the same tangent plane at a common point. When the characteristic is even, we determine the configuration arising from the intersection of H(3, q2) and Q−(3, q2), provided that the generators of H(3, q2) that are tangents with respect to Q−(3, q2) are the extended lines of a symplectic generalized quadrangle W(3, q) embedded in H(3, q2). As a by-product, new infinite families of hyperovals on H(3, q2) are constructed.
Economic Analysis of Pre-trial Negotiations: A Behavioral Approach
Authors: Dandekar Suyog Ravindra , Raja Angara V. 
Published: April 2015

Abstract
The paper provides a behavioral approach to analysis of pre-trial negotiations. This paper differs from earlier studies in that the most likely outcome forms the basis on which the parties assess their benefits and costs. This is based not on precise calculations of expected values, but on the expectations of the parties which depend on assessment of relative strengths of their case. This is modelled as an outcome of an imperfect cognitive process which is characterized by coherence based reasoning and insensitivities to actual probabilities, and legal discovery. Furthermore, the paper identifies factors which affect bargaining power and how bargaining power affects settlement amounts.
Lasers in InP generic photonic integration technology platforms
Authors: Latkowski Sylwester , Lenstra Daan 
Published: April 2015

Abstract
A review is given of a number of lasers in a form of photonic integrated circuits realized on InP substrate using a generic integration approach. The potential of these photonic circuits lies in their compactness, low power consumption, and significant reduction of fabrication cost by realization in generic foundry runs. Generic integration platforms offer the possibility of realizing functionally advanced photonic circuits using combinations of just a few standardized and parameterized building blocks. This vibrant field opens new doors to innovative product development for SMEs as well as curiosity-driven research.

Published: April 2015

Zusammenfassung:
Akademische wie öffentliche Bibliotheken sind gegenwärtig mit zahlreichen veränderten Rahmenbedingungen und Herausforderungen konfrontiert (z. B. technologische Innovationen; Dynamik von Bildung und Wissensgesellschaft; Ressourcenknappheit): Wie sollen Bibliotheken der Zukunft konzipiert werden? Wie kann die Leistungsmessung von der Inputlastigkeit befreit werden? Welches sind die identitätsbildenden Aufgaben von Bibliotheken und wie können sie sich als kompetitive Akteure etablieren? Diese Herausforderungen und Entwicklungsperspektiven, so die These des vorliegenden Aufsatzes, können ohne systematisches Qualitätsmanagement und strategische Steuerung (Governance) nicht effektiv bewältigt werden. Denn die erforderlichen Kompetenzen, Strukturen und Prozesse, die im Folgenden diskutiert werden, müssen auf strategisch orientierte Qualitätsentwicklung ausgerichtet sein.
Die Verhältnisse sind unterschiedlich, ein normierter Vergleich macht keinen Sinn. Ein Statement zum BIX.
Authors: Moeske Ulrich 
Published: April 2015

Zusammenfassung:
Der BIX als Instrument, um die Leistungen verschiedener Bibliotheken miteinander zu vergleichen, liefert in vielen Teilen nicht nur ein verzerrtes Bild der bibliothekarischen Praxis, sondern schadet darüber hinaus. Besonders in seiner Verwendung als Mittel zur Selbstdarstellung in der Öffentlichkeit. Durch einen fahrlässigen Umgang mit dem zugrunde liegenden Zahlenmaterial, den so genannten „harten Fakten“, eröffnet der BIX seinen Rezipienten vielfältige Interpretationsspielräume. Insgesamt stellt sich damit die grundlegende Frage: Sollte man den BIX besser abschaffen?

Zusammenfassung:
Seit rund 15 Jahren gibt es den Bibliotheksindex BIX als Instrument einer vergleichenden Messung von Aufwand und Leistungen von öffentlichen kommunalen Bibliotheken aller Größenklassen. Hier soll der Versuch unternommen werden, die Aussagen des BIX anhand von vier typischen Fragstellungen, die die Kommunalpolitik im Zusammenhang mit Bibliotheken aufwirft, zu behandeln und zu prüfen, inwieweit der BIX Antwortpotentiale bereit hält und eine Rückwirkung auf die kommunale Entscheidungsebene haben kann.
Are regulation-driven performance criteria still acceptable? – The German point of view
Authors: Orth Matthias 
Published: April 2015

AbstractPerformance criteria should be a challenge for the laboratories to improve their quality. In countries with mandatory proficiency testing, the definition of performance criteria is a particular issue. If the definition of performance criteria is mandated from the regulatory bodies to medico-scientific institutions, scientific approaches (i.e., based on biological variation), the state-of-the-art approach (i.e., based on technical feasibility) as well as medical needs can be used to set up performance criteria such as the Richtlinie der Bundesärztekammer (RiliBÄK; Guideline of the German Medical Association on Quality Assurance in Medical Laboratory Examinations) in Germany. The experiences with RiliBÄK show that these performance criteria have to be revised on an ongoing basis.
Effects of Ultrasonic Treatment on Microstructure and Properties of Al-Based Composites Reinforced by In Situ Al2O3 Nanoparticles
Authors: Chen Cunguang , Guo Zhimeng , Luo Ji , Wang Wenwen , Hao Junjie 
Published: April 2015

AbstractAn investigation on the microstructure of as-cast Al-Mg-Cu composites reinforced by in situ nano-sized Al2O3 dispersoids with ultrasonic treatment showed that ultrasonic treatment of the melt prior to casting had a significant effect on the size and sphericity of α-Al dendrites as well as on the size, continuity and sphericity of intermetallic particles (Al2CuMg) formed during cooling and solidification of the composite. More importantly, Al2O3 nanoparticles were uniformly distributed inside the grains, which were in situ produced by the displacement reaction between Al and CuO in the melt under ultrasonic treatment. The microstructural effects were mainly attributed to the cavitation and streaming phenomena which took place during ultrasonic treatment in the melt. The mechanical properties were investigated by tensile tests and hardness measurements. Ultrasonic treatment caused a significant increase in the yield strength (~43%), ultimate tensile strength (~32%) and hardness (~13%), and simultaneously slight improvement in the ductility.
A Medical System for Supporting Civilian Crisis Response
Authors: Ren Chiang H. , Smith William K. , Christensen James 
Published: April 2015

AbstractThis paper examines the growth of mobile communications, electronic health records, and clinical decision support technologies and formulates the concept for a system that leverages these technologies to enable the general public to better support medical response during and after crisis events. Recognizing that data for modeling how people will react to and behave with such a system is very limited, the initial analysis was directed toward the potentials of civilian users, operations centers with remote medical advisors, and the new medical system for civilian response. Using relational diagrams, system operations for when the user is confronting a massive crisis, coping with an isolated emergency, or conducting self-training are described to encourage the initiation of pilot projects with user test groups. There are risks in shifting the dynamics between first responders and the people they are trying to save. However, the life-saving potential of emerging technologies demands further investigation and testing.
International Trade, Fairness, and Labour Migration
Authors: Loriaux Sylvie , Herwig Alexia 
Published: April 2015

AbstractThis paper aims to show that fairness in trade calls for relaxing existing WTO rules to include a greater liberalisation of labour migration. After having addressed several objections to global egalitarianism, it will argue, first, that the world’s rich and the world’s poor participate in a same multilateral trading system whose point is primarily to reduce trade barriers, and hence to establish global economic competitions, in order to raise their standards of living; second, that these competitions are subject to requirements of formal and substantive fairness; and, third, that the substantive fairness of the competitions that are taking place in the field of trade in goods is likely to require a greater liberalisation of labour migration, especially low-skilled labour from developing countries.
A Theory of Fairness in Trade
Authors: James Aaron 
Published: April 2015

AbstractA theory of fairness in international trade should answer at least three questions. What, at the basic level, are we to assess as fair or unfair in the trade context? What sort of fairness issue does this basic subject of assessment raise? And, what moral principles must be fulfilled if trade is to be fair in the relevant sense? This discussion presents answers to these questions that derive from a “constructivist” methodology inspired by John Rawls and the social contract tradition.

Morphology and thermomechanical properties of epoxy composites highly filled with waste bulk molding compounds (BMC)
Authors: Matykiewicz Danuta , Barczewski Mateusz , Sterzyński Tomasz 
Published: April 2015

Abstract
The aim of this study was to produce epoxy composites highly filled with waste bulk molding compounds (BMC). The used amount of filler ranged from 30 wt% to 60 wt%. The influence of BMC on the epoxy resin curing process was monitored with the differential scanning calorimetry (DSC) method. Fourier transform infrared (FTIR) spectroscopy was used to evaluate the chemical structure of composites. The mechanical and thermal properties were examined by means of dynamic mechanical thermal analysis (DMTA), the Charpy method and the Shore D test. The fracture surface morphology of composites was observed with scanning electron microscopy (SEM). The storage modulus G′ of the epoxy composites with BMC was higher than the reference epoxy sample and significantly dependent on filler content. All investigated materials showed similar values of hardness, but at the same time low values of impact strength. Therefore, obtained composites can be used as low cost coating materials.
A family of triangular Hermite finite elements complementing the Bogner–Fox–Schmit rectangle
Authors: Gileva Lidia , Shaidurov Vladimir , Dobronets Boris 
Published: April 2015

AbstractThe Bogner-Fox-Schmit rectangular element is one of the simplest elements that provide continuous differentiability of an approximate solution in the framework of the finite element method. However, it can be applied only on a simple domain composed of rectangles whose sides are parallel to two different straight lines.We propose a new family of triangular Hermite elements that involves straight-sided elements and elements with a curved side. Such an element can be used in combination with the Bogner-Fox-Schmit element near the boundary of an arbitrary polygonal domain or a domain with a curved part of the boundary and provides continuous differentiability of an approximate solution in thewhole domain up to the boundary.

Quinclorac and Aminocyclopyrachlor Movement in Sandy Soils
Authors: Adams Jason W. , Lym Rodney G. 
Published: April 2015

AbstractThe Sheyenne National Grassland (SNG) is a native tall grass and mixed grass prairie located in southeastern North Dakota. Approximately half of the SNG has been invaded by leafy spurge (Euphorbia esulaL.) and control methods have been limited. Many herbicides cannot be utilized at the SNG due to sandy soils (> 80%) and shallow groundwater, nor can they be applied near the western prairie fringed orchid (Platanthera praeclaraSheviak and Bowles), a federally listed threatened plant found on the SNG. Quinclorac and aminocyclopyrachlor were considered for use on the SNG but potential to enter the groundwater was unclear. Movement of quinclorac and aminocyclopyrachlor was evaluated in 70 cm soil columns that simulated field conditions from five ecological sites. Quinclorac leached further following the heavy rainfall event of 15 cm in 48 h compared to the annual precipitation of 51 cm applied over 9 wk. Quinclorac leached approximately 45 cm into the soil profile averaged over all soil types and both precipitation events but never exceeded 65 cm regardless of soil type. Aminocyclopyrachlor leaching was greater than quinclorac and moved through all soil types into the leachate following both watering regimes. Desorption of both herbicides was incomplete. Approximately 10 and 32% of applied aminocyclopyrachlor and quinclorac, respectively, remained in the top 5 cm of soil regardless of soil type or watering regime. Quinclorac but not aminocyclopyrachlor was considered suitable for use at the SNG to control leafy spurge and has the added benefit of not harming the western prairie fringed orchid.

Abstract

Background.
Pemetrexed is a commonly used treatment for platinum-resistant advanced urothelial carcinoma (UC) based on objective response rates of 8% and 28% in two small phase II studies. To address the discrepancy in reported response rates and to assess efficacy and toxicity outside of a clinical trial setting, we performed a large retrospective analysis of pemetrexed use at Memorial Sloan Kettering Cancer Center. We also investigated candidate prognostic factors for overall survival in this setting to explore whether the neutrophil-lymphocyte ratio (NLR) had independent prognostic significance.

Patients and Methods.
Patients receiving pemetrexed for platinum-resistant advanced UC between 2008 and 2013 were identified. The Response Evaluation Criteria in Solid Tumors (RECIST, version 1.1) were used to determine response rate. Kaplan-Meier and Cox regression analyses were used to examine the association of various factors with efficacy and survival outcomes. Hematologic toxicity and laboratory abnormalities were recorded.

Results.
One hundred and twenty-nine patients were treated with pemetrexed. The objective response rate was 5% (95% confidence interval: 1%–9%), and the median duration of response was 8 months. Median progression-free survival (PFS) was 2.4 months, and the 6-month PFS rate was 14%. There was no significant difference in response rate by age, Eastern Cooperative Oncology Group (ECOG) performance status, or number of prior therapies. On multivariable analysis, ECOG performance status (p &lt; .01), liver metastases (p = .02), and NLR (p &lt; .01) had independent prognostic significance for overall survival.

Conclusion.
This 129-patient series is the largest reported data set describing pemetrexed use in advanced UC. Activity was modest, although discovery of molecular biomarkers predictive of response would be valuable to identify the small subset of patients who do gain significant benefit. Overall, the data highlight the urgent need to develop novel therapies for these patients.
nab-Paclitaxel in Combination With Weekly Carboplatin With Concurrent Radiotherapy in Stage III Non-Small Cell Lung Cancer
Authors: Lammers Philip Edward , Lu Bo , Horn Leora , Shyr Yu , Keedy Vicki 
Published: April 2015

Abstract

Lessons Learned
The concomitant use of weekly nab-paclitaxel and carboplatin with concurrent radiotherapy was demonstrated to be a safe therapeutic approach in this phase I trial of 10 evaluable patients with stage III NSCLC. Despite the lack of systemic glucocorticoids, there were no reported infusion reactions or cases of peripheral neuropathy in this trial, both of which are known to occur with the use of paclitaxel.

Background.
Unresectable stage III non-small cell lung cancer (NSCLC) has a 5-year survival rate of 20%, and concurrent chemoradiotherapy results in significant toxicity with the use of current chemotherapeutic agents. nab-Paclitaxel was approved by the U.S. Food and Drug Administration in October 2012 for use along with carboplatin in advanced NSCLC. This study was undertaken to determine the maximum tolerated dose and dose-limiting toxicities (DLTs) of weekly nab-paclitaxel given in combination with carboplatin and concurrent radiotherapy in patients with unresectable stage III NSCLC.

Methods.
Escalating doses of once-weekly nab-paclitaxel were given along with once-weekly carboplatin area under the plasma concentration time curve (AUC) of 2 and concurrent radiotherapy 66 Gy in 33 fractions, followed by 2 cycles of carboplatin and nab-paclitaxel consolidation chemotherapy.

Results.
Eleven patients were enrolled and received treatment per protocol, with 10 evaluable for efficacy and toxicity. At dose level 1 (nab-paclitaxel 60 mg/m2), 2 DLTs were observed: esophagitis and radiation dermatitis. Six patients were enrolled at dose level 0 (nab-paclitaxel 40 mg/m2) with no DLTs. Nine of 10 evaluable patients had a partial response.

Conclusion.
Concurrent chemoradiotherapy with nab-paclitaxel 40 mg/m2 and carboplatin AUC 2 is a safe and well-tolerated therapeutic regimen in patients with stage III NSCLC. A separate phase I/II study to evaluate the efficacy of this regimen is under way.
Self-Image Profile in Children and Adolescents with Attention Deficit/ Hyperactivity Disorder and the Quality of Life in Their Parents
Authors: Gormez Vahdet , Forbes Fiona C. M. 
Published: April 2015

Objective We explored the impact of clinical response to treatment for Attention Deficit/Hyperactivity Disorder (ADHD) in children and adolescents on the subsequent changes in their self-image profile, the quality of life of their parents, and its effect on socio-demographic variables. Method Conners Rating Scales for Parents (CPRS-R) and for Teachers (CTRS-R) completed at the time of entry to the service were repeated to measure clinical response to treatment; the Self-image Profiles for Children (SIP-C) and Adolescents (SIP-A), the World Health Organization Quality of Life (WHOQoL) questionnaire and postcode data were used to evaluate other domains. Results Data was collected for 53 boys (84%) and 10 girls (16%) with current mean age 11.5 years. Four-fifths (51/63) received pharmacological treatment and all parents were offered group parent training program. The only subscale in CPRS-R to show significance was the ADHD Index. The CTRS-R demonstrated statistically significant improvement ( p < 0.01) in most subscales. On the Self-image Profile, children reported themselves as more Kind ( p < 0.012), more Helpful ( p < 0.038) and less Bossy ( p < 0.047). Comparison of pre- and post-treatment scores on QoL revealed no significant changes; however, correlations of QoL responses against CPRS post-treatment revealed significant negative relationships in a number of instances. Parents living in less deprived areas felt their lives were more meaningful and less likely felt negatively about themselves (p = 0.04, N = 26, rho = 0.405). Conclusion Clinical improvement in ADHD symptoms was positively correlated with some improvement in the Self-image Profile of children and adolescents, but its impact on the QoL in parents was limited.
