Habitat rehabilitation in urban waterways: the ecological potential of bank protection structures for benthic invertebrates

Compensating for the adverse ecological impacts of waterway development and improving their ecological functioning to achieve good ecological potential (GEP) have become mandatory within the European Union (EU). The technical rehabilitation measures presented here aim to functionally minimize the hydraulic impacts of navigation on aquatic biota in highly urbanized waterways. Their ecological functioning and potential to enhance biodiversity locally was assessed by comparing their macro-invertebrate community composition with nearby non-restored sites. Rehabilitation led to lower hydraulic impact on the littoral zone, which in turn led to the presence of otherwise missing macrophytes and the occurrence of organic mud habitats colonized by invertebrates typically rare in urban waterways. While the control sites were dominated by few, mostly invasive taxa in vast numbers, the rehabilitated sites exhibited a highly diverse community with 22 protected mollusc and insect taxa typically found in the oxbow communities of natural rivers. This major improvement was however not detected using the core metrics of the legally required national assessment tools of the EU Water Framework Directive. Overall results proved the success of this type of rehabilitation measure with respect to improving biodiversity, but they also showed the limiting and key factors influencing the macro-invertebrate communities of highly deteriorated urban waterways. Indeed, future implementations of this type of rehabilitation measure should consider spatial extent, water exchange rates, temporal succession of vegetation and adaptive management to improve its ecological functioning.     

Evidence Review on Labour Market and Job Place Retention: Mentoring Pathways Towards Employment

In Europe, there are four main active labour market programs: training, job search assistance, wage subsidies and subsidized public sector employment. Literature indicates that among all four, job search assistance, which includes mentoring, is the active employment policy with the most positive results. This paper, an output of an European funded project work package, is aimed to answer the question ‘What is there that says that mentoring is effective in job place retention?’ In order to answer this question, we conducted a literature review. In terms of content, our literature review’s results could be categorized into 14 main topics: Retention, Employee, Supervisor, Leadership, Education, Health Care, Management &; Marketing, ICT &; IT, Finance, Programme, Benefits, Mentee, Mentor, Less positive about mentoring. In addition to the academic literature review, we conducted a review in four different EU countries: Cyprus, Romania, Hungary and Portugal. Based on these reviews we will discuss the recommendations considering the three types of actors present in an effective mentoring process: mentoring coordinator, mentor and mentee.     

An optimal k of kth MA-ARIMA models under MA(q) models

In this article, we discuss finding the optimal k of (i) kth simple moving average, (ii) kth weighted moving average, and (iii) kth exponential weighted moving average based on simulated MA(q) model. We run a simulation using the three above examining methods under specific conditions. The main finding is that, 5th Exponential Weighted Moving Average (5-th EWMA) Autoregressive Integrated Moving Average (ARIMA) model is the best forecasting model among others, which means the optimal k = 5. For Turkish Telecommunications (TTKOM), stock market real data reveals the similar results of the simulation study.     

Trajectories of team and individual sports participation in childhood and links with internalizing problems

The purpose of this 5-year longitudinal study is to identify trajectories of team and individual sports participation in childhood, and to compare these trajectories on different types of internalizing problems. Parents reported their children's annual sports participation from the ages of 6–10 (n = 785) and teachers reported internalizing problems (depression, anxiety, social withdrawal) at the beginning and at the end of this period. The study used latent class growth analyses to identify two trajectories of team sports and two trajectories of individual sports participation were identified: (1) high participation, and (2) low participation. Considering baseline level of internalizing problems and gender, children in the high participation team sports trajectory show significantly fewer depression, anxiety, and social withdrawal behaviors at age 10 than those in the low participation team sports trajectory. No differences between individual sports trajectories were observed. Comparison with joint trajectory groups partially confirmed these results but also showed that sustained participation in multiple individual sports could also be linked to decreased anxiety. Our findings suggest that participation in team sports should be encouraged to promote certain aspects of children's mental health.     

Developmental changes in mothers’ perception of knowledge,solicitation, and child disclosure during middle childhood

Parents can actively seek knowledge (solicitation) or receive information provided willingly by the child (disclosure). In adolescence, disclosure is the main source of parental knowledge, but its importance may take root earlier in the course of development. We examined: 1) the factor structure of an instrument adapted for middle childhood measuring maternal perception of knowledge, solicitation, and children's self-disclosure; 2) changes in these dimensions over middle childhood; and 3) the respective contribution of solicitation and disclosure to parental knowledge. The mothers of 793 elementary school students (61.5% boys, 80.2% Canadian-born) completed a questionnaire annually from Grades 1 to 4. Multilevel confirmatory factor analysis confirmed the instrument's structure at all time points. Growth curve analyses showed that mothers’ perception of knowledge slightly declined from Grades 1 to 4. With respect to mothers’ perceived parental solicitation and child disclosure, gender interactions emerged. Solicitation declined for girls but remained stable for boys, while disclosure declined for girls but increased for boys over time. In addition, mothers' perception ofdisclosure and solicitation are both main sources of maternal knowledge regardless of age and gender in middle childhood.     

Do Adolescents Intervene in Intergroup Bias-based Bullying? Bystander Judgments and Responses to Intergroup Bias-based Bullying of Refugees

This study examined 587 Turkish adolescents’ (M_age = 13.14, SD = 1.61) judgments and bystander responses towards hypothetical intragroup interpersonal (Turkish victim) and intergroup bias-based (Syrian refugee victim) bullying. Intergroup factors and social-cognitive skills were assessed as predictors. Findings revealed that adolescents were less likely to see bullying as acceptable and less likely to explicitly support the bully in intragroup interpersonal bullying compared to intergroup bias-based bullying. Further, adolescents with higher theory of mind and empathy were more likely to evaluate intergroup bias-based bullying as less acceptable and more likely to challenge the bully. Adolescents’ prejudice and discrimination towards refugees were predictors of bystander judgments and responses to intergroup bias-based bullying. This study provides implications for anti-bullying intervention programs.     

Towards sustainability by aligning operational programmes and sustainable performance measures

Abstract

In the last decades, sustainable concerns have increasingly gained importance to organizational survival, and Lean/Six Sigma approaches are becoming more and more outstanding in order to improve sustainability performance. This article aims to evaluate the degree of importance of sustainable performance measures of Brazilian organizations and to propose guidelines to achieve sustainability by aligning these measures with operational improvement programmes. Multiple data collection methods were applied as theoretical literature review, questionnaire survey and semi-structured interviews with industry professionals and academic researchers. The findings show that it is the corporate responsibility to focus their efforts on both operational improvement programmes and sustainable initiatives in order to achieve better environmental protection, corporate reputation, quality management, cost performance and suppliers relations, as they are considered to be more important on organizational sustainability.     

Homosexuality in Turkey: Strategies for Managing Heterosexism

The goal of this study was to identify the strategies used by young homosexuals to manage their sexual minority status in Turkey. In-depth interviews were conducted with 15 self-identified homosexual university students. The data on the strategies employed by homosexuals suggested a categorization of these strategies into four interrelated areas: strategies employed in the process of self-acceptance; strategies to manage sexual stigma and prejudice; strategies specific to the coming-out process; and the strategies used while openly expressing their sexual identities.     

Remittances and Calorie Consumption Nexus in Algeria

This study investigates the cointegration and causal relationships between remittances and calorie consumption as an indicator of food security in Algeria. We estimate the calorie demand function for the period 1970‐2008, using two different cointegration tests Johansen and Juselius ( 1990 ) and autoregressive distributed lag (ARDL) bounds testing approach proposed by Pesaran et al. ( 2001 ) and Granger causality test based on Vector Error Correction Model. We find that: (1) GDP per capita affects calorie consumption positively and significantly; (2) income elasticity of calorie consumption is 0.16 in the short run and 0.60 in the long run; (3) remittances positively and significantly influence calorie consumption in the long run; (4) remittance elasticity of calorie consumption is 0.05 in the long run; (5) based on the causality test remittances influence calorie consumption directly and indirectly via GDP per capita in the long run.
