    This study explores the interdependencies of aquaculture markets in the Philippines by establishing the price cointegration between the wholesale and retail prices of three major species commonly farmed in the country, i.e., milkfish, tilapia, and shrimp. The co-movements of wholesale prices between and among key markets for each species are also investigated. Moreover, exogeneity in prices is established using the Granger-causation model to determine the existence of price leaders among these markets. These information are crucial because they may provide a better understanding of the efficiency in price formation across production and consumption centers. Thus, aquaculture producers and traders may use these information as basis for more efficient farm management and marketing decisions. Appropriate policies for the development of markets for the three aquaculture species are also identified in this study. Such policies are expected to contribute towards more efficient pricing and distribution of benefits among market players and stakeholders. These benefits are expected to manifest through the system of grading standards for fish traded in local markets, and the choice of cost-effective technologies in grow-out and post-production practices.

    Medical device infections, commonly caused by S. epidermidis are difficult to treat due to the formation of biofilms on the medical device surface which protect S. epidermidis against host immune defences and antibiotics. This project aimed to further our understanding of the interactions between S. epidermidis, and fibroblasts or macrophages in the presence of uncoated or whole-blood coated titanium (Ti) and titanium alloy (TiAlV) discs. S. epidermidis and fibroblasts/macrophages were cocultured on Ti or TiAlV discs for 6 and 24 h. The resulting samples were then analysed in one of three ways, 1) supernatant assayed for fibroblast/macrophage cytokine expression; 2) bacterial RNA extracted to analyse transcription of adhesion and biofilm associated genes; 3) samples prepared for visualisation using confocal microscopy and scanning electron microscopy. Cytokine analysis found increased expression of various cytokines involved in the regulation of immune responses to injury and infection, including IL-1ÎČ, MCP-1 and MIP-3α or IL-8, MIF, IFN-Îł by macrophages and fibroblasts respectively on uncoated Ti, and IL-1α, IL-6 and TNF-α by fibroblasts on pre-coated Ti. RT-qPCR of S. epidermidis found that gene transcription differed depending on disc or culturing conditions, indicating that both host cells and surfaces influence attachment and biofilm formation. Microscopy showed the adherence of S. epidermidis, macrophages and fibroblasts to discs in monoculture and co-culture, however, by 24 h, fibroblasts detached implying that S. epidermidis impacts the ability of fibroblasts to survive on the discs. To conclude, the results suggest that Ti or TiAlV discs, S. epidermidis and macrophages/fibroblasts interact with and affect each other during the initial stages of infection, with S. epidermidis pathogenesis being further influenced by the presence of host factors. This work is clinically relevant and directly translational to improving the treatment and diagnosis of medical device infections, which remain a burden on the NHS

    Training Friends and Overseas Relief: The Friends Ambulance Unit and the Friends Relief Service, 1939 to 1948

    Get PDF
    This transnational case study investigates the establishment and development of training programs by two British faith-based voluntary relief organizations, the Friends Ambulance Unit (FAU) and the Friends Relief Service (FRS), during the Second World War and explores the implementation of learned skills by members of those organizations working during the immediate postwar period in the British Occupation Zone in Germany. It contributes new perspectives to scholarship on humanitarianism as it highlights both the continuities and ruptures in the approaches to and practices of humanitarian aid. It identifies the Quaker traditions that shaped the work of the FAU and FRS—particularly the core principles of promoting self-help, impartiality, democratic structures, and internationalism—as they delivered relief and fostered the rebuilding of communities in war-torn northern Germany. It demonstrates how small voluntary organizations integrated their values into the new relief structures of planning-mindedness, professionalization and international collaboration that also characterized the larger relief organizations. Although the FAU and FRS shared in their convictions of pacifism, goodwill, and humanitarian service, the two organizations conceptualized their role in relief differently and reflected those differences in their respective training programs and to a substantial extent in their postwar service. The FAU focused on the “first stage” of emergency relief that focused on working alongside military bodies to provide medical and material aid to both civilians and the military. In contrast, the FRS focused on the “second and third stages” that centered on providing impartial relief and rehabilitation to civilian populations that did not require assistance or direction from the military. To provide aid in the “second and third stages,” the FRS trained volunteers for postwar emergency relief and rehabilitation as well as how to foster reconciliation among all populations impacted by the war. Training programs for both the FAU and FRS believed that by integrating past experiences as well as contemporary developments to the approach and practice of humanitarian aid, their relief teams would provide efficient and effective relief in the postwar period. By retaining their core principles and traditional approaches to relief work as well as adopting new professional methods to dispense aid, the relief teams sent to the British Occupation Zone in 1945 exhibited an impressive and unique flexibility as they worked with and alongside displaced populations, camp victims, refugees, and Germans in a landscape engulfed with destruction and displacement

     ABSTRACT Schizophrenia is a persistent psychotic disorder that includes disorders of behavior, thoughts, emotions, and perceptions. Paranoid schizophrenic is usually characterized by delusions of persecution. There are various background that support paranoid schizophrenic. One of the back ground could be explained through humanistic paradigm based on the theory of Carl Roger. Carl Rogers explained that every human being needs to be loved and accepted or called get a positive regard. Positive regards from parents would determine the personality of the children whether conditional or unconditional positive regards. The aim of this research is to determine the dynamics of the problems people with paranoid schizophrenia through humanistic paradigm approach. This is a single case qualitative research with case study as its method. Datas of research are retrieved integration techniques, which is combined observation, interview, and psychological tests. This study shows that paranoid schizophrenia is caused by the lost of dependency object who usually protect schizophrenic’s self-esteem. Conditional positive regards are the former caused of paranoid schizophrenia. As the absence of emotion focused coping and withdrawal tendency caused by conditional positive regards from parents, schizophrenic would form a delusion of persecution to maintain their self-esteem when the depencency object is gone. Delusions of persecution is used to decrease the incongruency between actual self and ideal self.  

    Posttraumatic Growth Experiences of Displaced Hurricane Maria Survivors Transitioning to Permanent Housing

    Natural disasters such as floods, hurricanes, or wars can significantly impact the world’s population and cause displacement from their homes or even their country. According to recent studies, 4.5 million natural disaster survivors were displaced in America in 1 year. Previous research regarding displaced survivors of natural disasters illuminated essential findings; however, there was limited research that explored their growth experiences after trauma. This qualitative study aimed to explore the posttraumatic growth (PTG) experiences of adult survivors of Hurricane Maria in Puerto Rico as they transitioned to permanent housing. Using a generic qualitative design, data were collected through semi-structured interviews with 10 adult displaced survivors who were fluent in English. The theoretical framework used was Tedeschi and Calhoun’s PTG theory with five tenants: (1) an increased appreciation for life, (2) meaningful relationships with others, (3) an increased sense of personal strength, (4) new possibilities, and (5) spiritual and existential matters. The data were analyzed using Braun and Clarks’ six-step thematic analysis process. The results highlighted that, within the chaos and upheaval left in the hurricane’s wake, the participants’ stories expose an extraordinary capacity for PTG. For positive social change, practitioners can incorporate PTG-focused approaches into therapy, and develop training programs. Local, state, federal, and international policymakers, emergency responders, and stakeholders can develop strategies to address resource and psychological needs in affected communities. Future research should include longitudinal, comparative, and quantitative studies, as well as investigations into resilience factors, cultural influences, and interventions tailored to fostering PTG
