Economics of irrigation water management : a literature survey with focus on partial and general equilibrium models

Water policy is an important topic on the agenda of the international community, and efficiency and equity in the allocation of water have emerged as important factors to be considered. Water pricing can be used to mitigate both the quantity and quality dimensions of water scarcity. This paper reviews partial equilibrium models and general equilibrium models that are relevant to irrigation water management issues. The most widely discussed issues in these models are water markets and water pricing. The interrelationships between economic, cultural, social, and political aspects that are related to water policy make it difficult to provide a comprehensive policy analysis. General equilibrium models of irrigation water management allow incorporation of both the irrigation sector and the other sectors in the economy and analysis of policies affecting each of them and the interaction between them. In addition to being able to address sector and household specifications, production factors, time horizon, pricing policies, and institutions such as water markets, general equilibrium models allow the analysis of the impact of water policies on equity and poverty alleviation. The authors conclude that, although there has been a significant increase in efforts to analyzewater related problems, analytical and empirical research in the field is still deficient and more effort is needed to address them.Environmental Economics&Policies,Water Supply and Sanitation Governance and Institutions,Town Water Supply and Sanitation,Water Supply and Systems,Water Conservation

Panic on the Streets of London: Police, Crime and the July 2005 Terror Attacks

In this paper we study the causal impact of police on crime by looking at what happened to crime before and after the terror attacks that hit central London in July 2005. The attacks resulted in a large redeployment of police officers to central London boroughs as compared to outer London - in fact, police deployment in central London increased by over 30 percent in the six weeks following the July 7 bombings. During this time crime fell significantly in central relative to outer London. Study of the timing of the crime reductions and their magnitude, the types of crime which were more likely to be affected and a series of robustness tests looking at possible biases all make us confident that our research approach identifies a causal impact of police on crime. Implementing an instrumental variable approach shows an elasticity of crime with respect to police approximately -0.3, so that a 10 percent increase in police activity reduces crime by around 3 percent.crime, police, terror attacks

Prototyping Component-Based Self-Adaptive Systems with Maude

Software adaptation is becoming increasingly important as more and more applications need to dynamically adapt their structure and behavior to cope with changing contexts, available resources and user requirements. Maude is a high-performance reflective language and system, supporting both equational and rewriting logic specification and programming for a wide range of applications. In this paper we describe our experience in using Maude for prototyping component-based self-adaptive systems so that they can be formally simulated and analyzed. In order to illustrate the benefits of using Maude in this context, a case study in the robotics domain is presented.Ministerio de Ciencia e Innovación TIN2009-08572Fundación Séneca-CARM 15374/PI/1

Development and evaluation of the coach-athlete relationship enhancement intervention

An expanding body of sport psychology theory and research has highlighted the central role of the coach-athlete relationship (CAR) in the performance, satisfaction and well-being of coaches as well as athletes. Models have been developed that identify the key dimensions of CAR quality and the interpersonal behaviour that maintains it, but there remains a need for interventions that support coaches and athletes to optimise their interpersonal skills. This can be done by harnessing recent advances in personality theory which emphasise a more holistic and developmental view of the person and provide a basis for greater mutual understanding and adaptive interpersonal behaviour change in the CAR. The aims of this study were to develop the Coach-Athlete Relationship Enhancement (CARE) intervention through an integration of the Enneagram personality typology with current models of the CAR, and then to evaluate the impact of the CARE intervention on CAR quality. Sixty-two university-level athletes and their nine coaches participated in the study. Quantitative and qualitative results indicate that the CARE intervention significantly enhanced CAR quality, including direct and meta-perceptions of closeness, commitment and complementarity, as well as co-orientation. Intervention outcomes included enhanced mutual understanding in the CAR, enhanced self-awareness, enhanced team relationships, and adaptive interpersonal behaviour change. These outcomes were associated with a shared awareness between coaches and athletes of their Enneagram personality type traits and motivations. Coach-athlete relationship quality was further enhanced by re-constructing coaches’ and athletes’ personal narratives based on self-descriptions of Enneagram type strengths, and a redefinition of individuals’ core motivations to incorporate adaptive interpersonal behaviour change

The development of a needs assessment of pediatric occupational therapists: learning needs for competency in mainland China

The growth and learning needs of pediatric occupational therapists working in the People’s Republic of China (PRC) have not been fully researched or documented at this time. Without a formal occupational therapy association, the communication and planning to identify these professional development needs can be challenging. WFOT resources available for non-member countries combine with some of the traditional occupational therapy resources and initiatives from neighboring member associations. Hong Kong and Taiwan provide practices and materials that reflect Chinese culture and assist in promoting the profession (Lin, 2014; Sinclair, 2015). Language nuances, historical and political issues can make direct transference to the mainland of China problematic. These activities help support occupational therapy as a distinct healthcare profession within these regions of the PRC but may have barriers to direct application in mainland China. A formal needs assessment of the occupational therapists has not yet been undertaken. The steps to develop a pediatric needs assessment are presented in this paper. Research confirms a facilitated needs assessment can assist in determining and understanding learning needs, preferences, patterns, and future topics (Newcomer, Hatry, & Wholey, 2015) for occupational therapists and the groups that provide them professional development training in mainland China. There are three distinct stakeholder groups identified for this research project: pediatric occupational therapists, professional development producers, and families of children receiving therapy services in mainland China. The research team works collaboratively with identified stakeholder partners to identify the training and growth needs of the pediatric occupational therapist to provide the required educational recommendations that will foster competency in practice. Both the occupational therapists and the providers of professional development activities gain a better understanding through participation in the program evaluation processes of surveying learning needs in the context of international evidence-based competency content. The implementation and dissemination of the program verifies, validates and provides a synthesis of perspectives and establishes a connection for the client’s input to the therapy services. The program evaluation summary recommendations are hypothesized to have an impact on improving the perception of the quality of pediatric occupational therapy services received by caregivers and families in mainland China
