Students\u27 Response to Ethical Dilemmas

The teaching of ethics in hospitality curricula is an important part of students’ overall education. Past research has indicated that college students are generally as ethically aware as their professional counterparts. The authors replicated a study by Damitio and Schmidgall (1993) in which over 700 college students were asked if they agreed with decisions in 15 hypothetical scenarios. Students were also asked if the decisions were in fact ethical. Results are reported. The authors use these results as further evidence that ethical awareness in hospitality students needs to be raised. There does not appear to be any change in students’ ethical awareness since the original study in the early 1990s. A discussion of the direction ethics education might take follows. Implications for hospitality curricula and hospitality students are analyzed. A course of action is recommende

Delirium in HIV-infected patients admitted to acute medical wards post universal access to antiretrovirals in South Africa

Background. Delirium is associated with increased mortality and length of hospital stay. Limited data are available from HIV-infected acute hospital admissions in developing countries. We conducted a prospective study of delirium among acute medical admissions in South Africa (SA), a developing country with universal antiretroviral therapy (ART) access and high burdens of tuberculosis (TB) and non-communicable disease.Objectives. To identify the prevalence of, risk factors for and outcomes of delirium in HIV-infected individuals in acute general medical admissions.Methods. Three cohorts of adult acute medical admissions to Groote Schuur and Victoria Wynberg hospitals, Cape Town, SA, were evaluated for prevalent delirium within 24 hours of admission. Reference delirium testing was performed by either consultant physicians or neuropsychologists, using the Confusion Assessment Method.Results. The study included 1 182 acute medical admissions, with 318 (26.9%) HIV-infected. The median (interquartile range) age and CD4 count were 35 (30 - 43) years and 132 (61 - 256) cells/µL, respectively, with 140/318 (44.0%) using ART on admission. The prevalence of delirium was 17.6% (95% confidence interval (CI) 13.7 - 22.1) among HIV-infected patients, and delirium was associated with increased inpatient mortality. In multivariable logistic regression analysis, factors associated with delirium were age ≥55 years (adjusted odds ratio (aOR) 6.95 (95% CI 2.03 - 23.67); p=0.002), and urea ≥15 mmol/L (aOR 4.83 (95% CI 1.7 - 13.44); p=0.003), while ART use reduced risk (p=0.014). A low CD4 count, an unsuppressed viral load and active TB were not predictors of delirium; nor were other previously reported risk factors such as non-opportunistic acute infections or polypharmacy.Conclusions. Delirium is common and is associated with increased mortality in HIV-infected acute medical admissions in endemic settings, despite increased ART use. Older HIV-infected patients with renal dysfunction are at increased risk for inpatient delirium, while those using ART on admission have a reduced risk

A selective procedure for the field isolation of pathogenic Streptococcus spp. of rainbow trout (Salmo gairdneri)

A procedure established for the selective isolation of the species of Streptococcus responsible for rainbow trout streptococcosis in South Africa, consisted of the inoculation of samples into nutrient broth which had been supplemented with 100 µg/ml of nalidixic acid, 160 µg/ml of oxolinic acid or 200 µg/ml of sodium azide. After incubation, the sample was plated onto tetrazolium agar on which the rainbow trout pathogenic Streptococcus species grew as a red colony. The colonies were isolated from the tetrazolium agar and identified as rainbow trout pathogenic isolates by biochemical and serological tests. In the laboratory the selective procedure is capable of detecting about 2 bacteria per ml. This procedure was used in the field and biochemically identical Streptococcus species were found in the mud and a freshwater crab from the water source of a site with a history of streptococcosis.The articles have been scanned in colour with a HP Scanjet 5590; 600dpi.

Current conservation status of the Blue Swallow Hirundo atrocaerulea Sundevall 1850 in Africa

The global Blue Swallow Hirundo atrocaerulea was classified as Vulnerable in 2010 on account of its small and rapidly declining population estimated at less than 1 500 pairs. We undertook this study to gain a better understanding of the current status and threats facing this migratory species. Three previously unknown areas that might be part of the species’ non-breeding range were identified in Kenya and northern Tanzania. Within its breeding range we identified three previously unknown areas of potentially suitable habitat, one in Tanzania and two in Malawi, which require further exploration. Population viability assessment predicted that the Blue Swallow population will decline by 8% in 10 years. The overall probability of extinction of the species in the wild is 3%. Minimum viable population size analysis suggests that a goal for the long-term conservation of the Blue Swallow should be to mitigate current threats that are driving declines such that the population increases to a minimum of 3 600 individuals. This should consist of at least 900 individuals in each of the four clusters identified, along with a minimum of 500 individuals in at least one of the meta-populations per cluster. The four clusters are located in (1) the southeasten Democratic Republic of the Congo, (2) highlands of southern Tanzania and northern Malawi, (3) eastern highlands of Zimbabwe and (4) South Africa and Swaziland. The current proportions of the Blue Swallow population in strictly protected and unprotected areas on their breeding grounds are 53% and 47%, respectively, whereas on their non-breeding grounds the corresponding percentages are 25% and 75%, respectively. Our reassessment of the Blue Swallow’s risk of extinction indicates that it continues to qualify as Vulnerable according to the IUCN/SSC criteria C2a(i).http://www.tandfonline.com/loi/tost202016-09-30hb2016Zoology and Entomolog
