Factors related with unintentional injuries in children with newly diagnosed attention-deficit/hyperactivity disorder

The aim of the present study was to investigate the factors associated with unintentional injury in children newly diagnosed with attention-deficit/hyperactivity disorder (ADHD). One thousand four hundred and thirty children between the ages of 6 and 18 who were diagnosed with ADHD for the first time in child psychiatry outpatient clinics were included in the present study. The socio-demographic information of the children, their developmental histories, chronic physical health conditions, comorbid psychiatric disorders, and information obtained via the Turgay DSM-IV-based Child and Adolescent Disorders Screening and Rating Scale were examined retrospectively. It was determined that 12.8% of the children (n = 183) experienced unintentional injury. It was established that age, male gender, disruptive behavioural problems, and low education levels among mothers were predictive of unintentional injuries. The results of the present study suggest that behavioural problems accompanying ADHD and comorbid psychiatric disorders are important in terms of unintentional injuries.     

Top Management Involvement in New Product Development: A Review and Synthesis

Established literature on new product development (NPD) management recognizes top management involvement (TMI) as one of the most critical success factors. With increasing pressure to sustain competitive advantage and growth, NPD activities remain the focus of close interest from top management in many organizations. TMI in the NPD domain is receiving increasing academic attention. Despite its criticality, there is no systematic review of the existing literature to inform and stimulate researchers in the field for further investigation. This paper introduces the current state of literature on TMI in NPD, synthesizes important findings, and identifies the gaps and deficiencies in this research stream. The contents of the selected articles, which investigated TMI in NPD, are analyzed based on the type of the study, level of analysis, research methodology, operationalization of TMI, and main findings. Additionally, other studies, which did not directly investigate TMI and support in NPD, but were sufficiently related, are briefly summarized. As a result of this detailed literature review, it can be stated that both exploratory and relational studies provide rich evidence on the critical role of top management in NPD. However, the identified gaps and deficiencies in this research stream call for a better theoretical understanding and well‐defined constructs of TMI in the NPD domain for different levels of analysis for future studies.     

The Renminbi and Poor‐country Growth

Discussions on how best to exit from global imbalances to create a more balanced world economy have ignored the impact on poor countries of proposals to redress these imbalances. This paper aims at filling that gap. It gauges the degree of renminbi (RMB) undervaluation; presents evidence on RMB undervaluation and China’s GDP growth rate; surveys the role of the real effective exchange rate – both its level and its stability over time – for underpinning growth in developing countries, especially in large dual economies such as China and India; and finally, presents new evidence on growth linkages between China and poor countries for the last two decades and surveys literature on potential displacement effects of RMB appreciation. The analysis allows broad conclusions to be drawn about the potential developing‐country beneficiaries and losers from various renminbi adjustment scenarios in the forthcoming years.     

Analysis of an integrated maximum covering and patrol routing problem

In this paper, we address the problem of determining the patrol routes of state troopers for maximum coverage of highway spots with high frequencies of crashes (hot spots). We develop a specific mixed integer linear programming model for this problem under time feasibility and budget limitation. We solve this model using local and tabu-search based heuristics. Via extensive computational experiments using randomly generated data, we test the validity of our solution approaches. Furthermore, using real data from the state of Alabama, we provide recommendations for (i) critical levels of coverage; (ii) factors influencing the service measures; and (iii) dynamic changes in routes.     

Sovereign bond yield spreads: A time-varying coefficient approach

We study the determinants of sovereign bond yield spreads across 10 EMU countries between Q1/1999 and Q1/2010. We apply a semiparametric time-varying coefficient model to identify, to what extent an observed change in the yield spread is due to a shift in macroeconomic fundamentals or due to altering risk pricing. We find that at the beginning of EMU, the government debt level and the general investors’ risk aversion had a significant impact on interest differentials. In the subsequent years, however, financial markets paid less attention to the fiscal position of a country and the safe haven status of Germany diminished in importance. By the end of 2006, two years before the fall of Lehman Brothers, financial markets began to grant Germany safe haven status again. One year later, when financial turmoil began, the market reaction to fiscal loosening increased considerably. The altering in risk pricing over time period confirms the need of time-varying coefficient models in this context.     

Rehearsal of professional practice: impacts of web-based collaborative learning on the future encounter of different disciplines

This study argues that the shift towards a more multidisciplinary professional life in contemporary design practice requires design curricula to equip students with collaborative skills. The study offers that by the aid of web-based collaborative learning (WBCL) in design education, different disciplines may be brought together during their education. A case study is held as a rehearsal of professional life; involving architecture and interior architecture students collaborating on a common project, using WBCL. The evaluations of the participating students about the process were analyzed. The findings convey that there is a mutual problem of recognition of professional domains. In order to diagnose and possibly reconcile tensions that may occur due to this problem in professional life, this paper asserts that integrating interdisciplinary work to the design curricula would be beneficial.
