The contribution of social support to children and adolescents' self-perception: The mediating role of bullying victimization

The purpose of this article is to report on a study that explores the linkages among self-perception, perceptions of social support, and bullying involvement among children and youth, with a focus on how bullying victimization mediates the association of social support and self-perception. We employ Harter's multidimensional model of self-esteem (1999; 2012), which highlights the inextricable link of social support to global self-esteem but does not explore the contribution of bullying involvement to this association. Our findings indicate that social support is associated with self-perception, and that traditional victimization mediates the association between social support and self-perception for three self-perception measures: social acceptance, physical appearance, and global self-worth. Contrary to our expectations, cyberbullying victimization was not found to mediate the relationship between social support and self-perception. These findings underscore the importance of exploring both traditional bullying victimization and cyberbullying victimization in relation to social support in order to understand their effect on development and wellbeing. More broadly, this study's finding that social support was a significant buffer to bullying victimization emphasizes the necessity of developing prevention and intervention strategies which are relationship-based and implemented early in young people's lives.     

What we learned from the Dust Bowl: lessons in science,policy, and adaptation

This article provides a review and synthesis of scholarly knowledge of Depression-era droughts on the North American Great Plains, a time and place known colloquially as the Dust Bowl era or the Dirty Thirties. Recent events, including the 2008 financial crisis, severe droughts in the US corn belt, and the release of a popular documentary film, have spawned a resurgence in public interest in the Dust Bowl. Events of the Dust Bowl era have also proven in recent years to be of considerable interest to scholars researching phenomena related to global environmental change, including atmospheric circulation, drought modeling, land management, institutional behavior, adaptation processes, and human migration. In this review, we draw out common themes in terms of not only what natural and social scientists have learned about the Dust Bowl era itself, but also how insights gained from the study of that period are helping to enhance our understanding of climate–human relations more generally.     

Logistics reorganization and management of the ambulatory pharmacy of a local health unit in Portugal

The Hospital Pharmacy of a Local Health Unit (LHU) in greater Oporto plays a major role in the community. In addition to providing medicines to the entire Internal Unit, it has created a service called "Hospital Ambulatory Pharmacy", which allows continued hospital treatments at home, in a more comfortable and familiar environment. This is mostly due uderfunding which has hindered recruitment of health professionals as well a growing concern for the comfort of patients as they convalesce. The Hospital Ambulatory Pharmacy’s main problems are both recurring stock-outs and over-stocks; the fact that medicines’s delivery routes are not completed, and that medical staff lacks awareness of the techniques to overcome the logistic issues involved. As a methodology, a context analysis was carried out, KPI's were created to quantify the problems and raise health professionals’ awareness of what was happening. Solutions for storage were analysed and visits were made to a central hospital to analyse the solutions adopted to solve the same problems. The most appropriate inventory management policies were considered for the organization of existing and further resources. We chose to create an Advanced Warehouse with Level Replenishment. The levels were defined considering the demand of each medicine and divided into three different classes to use the best strategy for each type of demand. Then, and with the help of the LHU IT team, the inventory management module of the information system was parameterized, so stock replenishment could be done electronically. All these changes resulted in a 30 % reduction in stock-out. At the beginning of the study, stock-outs would reach peaks of 6 %. These were reduced to 4.5 % at a point at which professionals were already more aware of the logistic problem, and finally to 1.5 %, in the final phase, at a time when the proposal had already been implemented. Over-stock was reduced by 66 %. Delivery routes were stipulated, and compliance was verified. A novel service developed to increase the well-being of patients monitored at home which it is intended to improve the service provided to the users and at the same time reduce operational costs.As a contribution to the knowledge, in addition to the case study presented to be a novelty in terms of scientific articles published because it is a service implemented in the distribution of medications to patients at home, mostly with oncologic diseases. Several methods from Lean Thinking were used, such as, Kanban System and Advanced Warehouse for inventory management levelling and optimization techniques, as well as, operational KPIs, with the purpose to reach out the improvement of program planning and evaluation. This approach resulted in some improvements, namely, the increase of the quality of the healthcare services for the population. And, in terms to reduce stock and excess stock-outs, to reduce inventory costs, setting the delivery routes, raising the entire medical team’s awareness of the problem and committing to optimization a reality.     

Using video vignettes in research and program evaluation for people with intellectual and developmental disabilities: A case study of the Leadership for Empowerment and Abuse Prevention (LEAP) project

People with intellectual and developmental disabilities (IDD) are often excluded from meaningful participation in research and program evaluation for various reasons, including protocols and measures that are inaccessible for people with varying cognitive and communication abilities. Emancipatory research models emphasize the importance of inclusive research practices. Video vignettes are a promising tool for research and program evaluation with people with IDD because they are standardized, they use visual imagery rather than relying on written or verbal communication, and they allow for distance from sensitive topics. The Leadership for Empowerment and Abuse Prevention (LEAP) project used video vignettes to evaluate a healthy relationship program for people with IDD. The authors discuss the process of piloting various protocols and measures, which then ultimately led to the use of video vignettes in the evaluation.     

Barriers and enablers to conducting cluster randomized control trials in hospitals: A theory-informed scoping review

BackgroundCluster randomized control trials (cRCTs) have unique challenges compared to single site trials with regards to conduct of the trial, and it is important to understand these barriers. The aim of this scoping review was to describe the current literature surrounding the implementation of the cRCTs in hospitals.MethodsThe search strategy was designed to identify literature relevant to conduct of cRCTs, with hospitals as the unit of randomization. Data was extracted and was mapped using the Consolidated Framework for Implementation Research (CFIR) as a codebook, which contains 39 constructs organized into five domains.ResultsTwenty-two articles met inclusion criteria and were included. 18 of 39 constructs of the CFIR were identified in coding, spanning four of the five domains. Barriers to the conduct of the trial were rarely reported as the main outcome of the study, and few details were included in the identified literature.ConclusionsThe review can provide guidance to future researchers planning cRCTs in hospitals. It also identified a large gap in reporting of conduct of these trials, demonstrating the need for a research agenda that further explores the barriers and facilitators, with the aim of garnering knowledge for improved guidance in the implementation.     

A Mixed Method Approach to Quality of Life Research: A Case Study Approach

Increased use of qualitative and quantitative methods in quality of life projects necessitates an examination of how to effectively work within a mixed method framework. The research objectives of this paper are to (1) operationalize the two goals of mixed method research (confirmation and comprehension) and (2) develop a strategy for using mixed methods in quality of life research. Face-to-face interview (qualitative) and telephone survey (quantitative) data from the Community–University Institute for Social Research Quality of Life (CUISR QoL) project in Saskatoon, Saskatchewan were used for operationalization. Overall, confirmation and comprehension were challenging concepts to operationalize. Seven benefits and four guidelines were developed and are presented as dynamic, rather than definitive, structures.     

Optimal pricing and production decisions in the presence of symmetrical and asymmetrical substitution

Firms may produce a variety of generally similar products or may practice “scientific pricing” or revenue management where the firm will offer similar or somewhat differentiated products in multiple market segments at different prices. Whenever generally similar products are available, the demand for the products is linked through the ability of the customer to substitute one product for another. One widely known type of demand substitution is referred to as inventory-driven substitution where a customer will substitute for a product that is out of stock by buying a similar product. A second type of substitution occurs as a response to price-differences when a customer substitutes a less expensive product for a similar higher priced product.     

Connecting external knowledge usage and firm performance: An empirical analysis

Prior research suggests that firms create breakthrough innovations by using external knowledge, but it also underscores the difficulties firms face in acquiring and applying external knowledge. In this paper, we combine these insights to examine the conditions under which external knowledge usage will either enhance or erode firm performance. In particular, we argue that high external knowledge usage has a negative effect on performance when firms enter multiple new product markets, but a positive effect on performance when firms using external knowledge have higher absorptive capacity. We find general support for our hypotheses, which we test using patent citation data from the global integrated circuit manufacturing industry. Our findings have important implications for managers of firms making strategic decisions about their firms’ product portfolios and the degree to which they use external knowledge.     

Reflections on experiential learning in evaluation capacity building with a community organization,Dancing With Parkinson’s

This paper discusses what was learned about evaluation capacity building with community organizations who deliver services to individuals with neurological disorders. Evaluation specialists engaged by the Ontario Brain Institute Evaluation Support Program were paired with community organizations, such as Dancing With Parkinson’s. Some of the learning included: relationship building is key for this model of capacity building; community organizations often have had negative experiences with evaluation and the idea that evaluations can be friendly tools in implementing meaningful programs is one key mechanism by which such an initiative can work; community organizations often need evaluation most to be able to demonstrate their value; a strength of this initiative was that the focus was not just on creating products but mostly on developing a learning process in which capacities would remain; evaluation tools and skills that organizations found useful were developing a theory of change and the concept of heterogeneous mechanisms (informed by a realist evaluation lens).
