Open plan and academe: pre- and post-hoc conversations

There now exists a strong body of evidence that creative workplaces can, in certain circumstances, exert beneficial influences on organisational cultures and outputs. Academia tends to resist such spaces and faculty buildings. The reasons are explored but the reactions of staff are not found to be different from those reported in the literature on general creative spaces. The success or failure of team oriented workspaces is in large part a socially constructed perception influenced by the manner of implementation and management. As elsewhere new workplaces are about new conversations. The cases studied lead to a model of the tensions inherent in workplace redesign.</p

Assessing Service Quality in the Ghanaian Private Healthcare Sector: The Case of Comboni Hospital.

The healthcare industry has become a paramount concern for most people in Ghana and the quality of services rendered to the patients in the private hospitals cannot be overemphasized. Patients need quality of services most and are willing to seek better services. The government has been the main provider of health care services in Ghana but recently, some Non-Governmental Organization’s (NGO’s), private individuals and stakeholders also provide health care services which has surged the competitiveness in creating more healthcare facilities in Ghana. This study seeks to explore patients' choice of selecting quality healthcare services and the factors that affect patient satisfaction in private hospitals using the case of Comboni Hospital in Sogakope, Ghana. The study therefore used the quantitative research method to collect the data and SPSS version 22 was used to analyze the data on high-quality healthcare. The SERVQUAL model was used as the measurement scale. Multiple regression analysis was used to reveal the effect of the independent variables (reliability, responsiveness, empathy, assurance, and tangibility) on the dependent variable (patient satisfaction). A detailed description in the analysis and the data processing identified the main factors affecting the general perceptions and patient preferences about their healthcare in the private hospital. The study revealed that there exist a positive result and perception for quality healthcare services without a negative expectation of the patient healthcare being compromised. The study recommends that both the government and the private agencies should consider the important aspects of the hospital’s healthcare management and also the policy and decision makers should have an efficient and effective standard that impact the quality of healthcare assessment in Ghana

Efficiency Effects Zimbabwe’s Agricultural Mechanization and Fast Track Land Reform Programme: A Stochastic Frontier Approach

A development goal pursued by the Zimbabwean government even before the much-maligned fast track land reform programme (FTLRP) was expansion of agricultural production through agricultural mechanization. This goal has been pursued through the acquisition and use of tractors by arable crop farmers in communal and resettlement state land delineated during the period following the launch of the FTLRP. This research project investigated the combined impacts of mechanization and an unplanned land reform on agricultural productivity in the Bindura district of Zimbabwe. The existing land policy and the issue of technical efficiency in agricultural productivity are assumed to be the drivers of the programme. It is likely that these issues will be important considerations in determining the sustainability of the mechanization policy. A multistage sampling technique was used to randomly select 90 farmers in the study area and structured questionnaires were used to collect demographic, investment and production data which were subsequently fitted by means of the Stochastic Frontier Model. Results revealed that mechanization was an important factor in the performance of the farmers who participated in the programme. The results also suggest that availability of land and access to production resources are crucial to farm productivity. Despite these, overall production and productivity remain low and the hyperinflationary situation triggered by supply constraints are only beginning to slightly ease. As the national unity government grapples with the huge task to restore growth in the Zimbabwean economy, it is important that these issues are borne in mind.Technical Constraints, Market Access, Agricultural Development, Induced Innovation Model, The Stochastic Frontier model, The Productive Efficiency and Mandate of Extension, Farm Management,

Frequency, factors and costs associated with injection site infections: findings from a national multi-site survey of injecting drug users in England.

BACKGROUND: Injection site infections among injecting drug users (IDUs) have been associated with serious morbidity and health service costs in North America. This study explores the frequency, factors and costs associated with injection site infections among IDUs in England. METHODS: Unlinked-anonymous survey during 2003/05 recruiting IDUs from community settings at seven locations across England. Self-reported injecting practice, symptoms of injection site infections (abscess or open wound) and health service utilisation data were collected using a questionnaire, participants also provided dried blood spot samples (tested for markers blood borne virus infections). Cost estimates were obtained by combining questionnaire data with information from national databases and the scientific literature. RESULTS: 36% of the 1,058 participants reported an injection site infection in the last year. Those reporting an injection site infection were more likely to be female and aged over 24, and to have: injected into legs, groin, and hands in last year; injected on 14 or more days during the last four weeks; cleaned needles/syringes for reuse; injected crack-cocaine; antibodies to hepatitis C; and previously received prescribed substitute drug. Two-thirds of those with an injection site infection reported seeking medical advice; half attended an emergency department and three-quarters of these reported hospital admission. Simple conservative estimates of associated healthcare costs range from pound 15.5 million per year to as high as pound 30 million; though if less conservative unit costs assumptions are made the total may be much higher (pound 47 million). The vast majority of these costs are due to hospital admissions and the uncertainty is due to little data on length of hospital stays. CONCLUSION: Symptoms of injection site infections are common among IDUs in England. The potential costs to the health service are substantial, but these costs need more accurate determination. Better-targeted interventions to support safer injection need to be developed and evaluated. The validity of self-reported symptoms, and the relationship between symptoms, infection severity, and health seeking behaviour require further research

Mapping occurrence of Taenia solium taeniosis/cysticercosis and areas at risk of porcine cysticercosis in Central America and the Caribbean basin

Background: This study aimed to map the occurrence of Taenia solium taeniosis/cysticercosis at national level within Central America and the Caribbean basin, and to map the distribution of porcine cysticercosis at first-level administrative subdivision level (department level) and the porcine population at risk. This zoonotic parasite is believed to be widely endemic across most of Latin America. However, there is little information readily available for Central America and the Caribbean basin. Taenia solium has been ranked the most important foodborne parasitic hazard globally and within endemic areas is a common cause of preventable epilepsy. Methods: We conducted a structured literature search in PubMed, supplemented and crossed-referenced with relevant academic databases, grey literature, and active searches in identified literature, to identify all records of T. solium presence in Central America and the Caribbean basin between 1986 and April 2017. To retrieve grey literature, government entities, researchers and relevant institutions across the region were contacted in an attempt to cover all countries and territories. Identified records containing data on porcine cysticercosis were geo-referenced to identify department level distribution and compared to modelled distributions of pigs reared under extensive production systems. Results: We identified 51 records of T. solium at the national level, covering 13 countries and an additional three countries were included based on World Organisation for Animal Health (OIE) reports, giving a total of 16 countries out of 41 with evidence of the parasite's presence. Screening records for porcine cysticercosis data at the departmental level confirmed porcine cysticercosis presence in 11 departments across six countries (Colombia, Guatemala, Honduras, Mexico, Nicaragua and Venezuela). Conclusions: When comparing these results to areas where pigs were kept in extensive production systems and areas where no information on porcine cysticercosis exists, it is apparent that porcine cysticercosis is likely to be underreported, and that a substantial part of the regional pig population could be at risk of contracting porcine cysticercosis. More detailed information on the distribution of T. solium and accurate burden estimations are urgently needed to grasp the true extent of this zoonotic parasite and the public health and agricultural problems it potentially poses
