Identifying leadership styles for managing employees at a Durban architectural firm.

Master of Business Administration. University of KwaZulu-Natal, Westville 2014.Architectural firms have owners who are rarely trained in management and how to manage employees. Managing an architectural firm requires the managers of the firm to have effective leadership styles for managing creative employees. This study proposed to identify what leadership styles managers should practice and how these leadership styles impact employees. The results of the study are intended to contribute to the development of managers into successful leaders. The aim of the study was to advance knowledge and assess the impact and importance of leadership in architectural firms. Managers and employees in architectural firms will benefit from the study. The theoretical areas that were used in the study included various leadership theories, traits, behavioural theories, contingency theories, and motivation theories. The objectives of the study were to indicate what leadership style works best in an architectural firm; to assess if creative employees of an architectural firm should be led differently; to find out what motivates employees at an architectural firm; and to study the effect of leadership styles on creative employees’ job satisfaction. The qualitative research approach was used, with in-depth, semi-structured interviews being conducted with 14 current/former employees and two managers from a Durban-based architectural firm. Judgmental sampling was employed and thematic analysis and interpretation was used to analyse the data. The results of the study revealed that the managers use an informal, consultative leadership style that encourages employees to contribute and make decisions. The findings identified that the managers can implement a distributed, participative, and team leadership style. The findings also indicated that the respondents are intrinsically motivated by enjoyment of their architectural work and it was found that the respondents get job satisfaction from their passion for architecture

The global variation of medical student engagement in teaching: Implications for medical electives.

INTRODUCTION: International medical electives, whereby undergraduates visit an institution in a country other than their own, are a common part of medical training. Visiting students are often asked to provide local teaching, which may be acceptable where the visitor is acting within the bounds of their own competency and the normal practices of both their home and host institutions. However, the extent to which teaching is an accepted student activity globally has not previously been described. This study aims to address this using an international survey approach. METHODS: A voluntary electronic survey, created using the Checklist for Reporting Results of Internet E-Surveys (CHERRIES) framework, was distributed across established international medical student networks. This assessed the involvement of medical students in teaching and the educator training they receive, with the intention of comparing experiences between high-income countries (HICs) and low/middle-income countries (LMICs) to gauge the engagement of both "host" and "visiting" students. RESULTS: 443 students from 61 countries completed the survey, with an equal proportion of respondents from LMICs (49.4%, 219/443) and HICs (50.6%, 224/443). Around two thirds of students reported providing teaching whilst at medical school, with most reporting teaching numerous times a year, mainly to more junior medical students. There was with no significant difference between LMICs and HICs. Around 30 per cent of all medical students reported having received no teacher training, including 40 per cent of those already providing teaching. CONCLUSION: This study suggests that students are engaged in teaching globally, with no difference between HIC and LMIC contexts. However, students are underprepared to act as educators in both settings. Providing teaching as part of an elective experience may be ethically acceptable to both host and home institutions, but needs to be supported by formal training in delivering teaching.NIHR Global Health Research Group on Neurotraum

Requirements for a lead compound to become a clinical candidate

A drug candidate suitable for clinical testing is expected to bind selectively to the receptor site on the target, to elicit the desired functional response of the target molecule, and to have adequate bioavailability and biodistribution to elicit the desired responses in animals and humans; it must also pass formal toxicity evaluation in animals. The path from lead to clinical drug candidate represents the most idiosyncratic segment of drug discovery and development. Each program is unique and setbacks are common, making it difficult to predict accurately the duration or costs of this segment. Because of incidents of unpredicted human toxicity seen in recent years, the regulatory agencies and public demands for safety of new drug candidates have become very strict, and safety issues are dominant when identifying a clinical drug candidate

The impact of COVID‐19 on HIV testing in the UK’s first Fast‐Track HIV city

Objectives To describe the impact that the COVID-19 pandemic has had on HIV testing in Brighton and Hove, United Kingdom. Methods All HIV tests performed in Brighton and Hove from January 2016 to June 2021 were extracted, de-duplicated and anonymized. Analysis was performed to compare the monthly numbers of tests and diagnoses before and during the pandemic across different services. Results The number of patients having tests for HIV in sexual health services (SHS) decreased by 64% in April 2020, followed by a recovery to baseline levels by the start of 2021. Similarly, the monthly number of diagnoses decreased drastically after April 2020, with almost half of diagnoses made by SHS in 2020 occurring in the three pre-pandemic months of the year. ‘Self-sampling’, used more by women and younger patients, has contributed significantly to the recovery. The number of patients tested in secondary care was seemingly unaffected by the pandemic. However, testing numbers were reduced in specialist services, whereas in the emergency department (ED) testing increased four-fold (most notably in the elderly) without finding any cases. General practice saw decreases in both the number of HIV tests performed and the number of new diagnoses made, which had not returned to baseline by June 2021. Discussion The COVID-19 pandemic has had a large impact on the number of HIV tests performed in Brighton and Hove with sizeable decreases in the number of patients tested likely leading to ‘missed’ diagnoses. By June 2021 testing had still not returned to normal across the city

A systematic approach to diverse, lead-like scaffolds from α,α-disubstituted amino acids.

A powerful strategy for the efficient lead-oriented synthesis of novel molecular scaffolds is demonstrated. Twenty two scaffolds were prepared from just four α-amino acid-derived building blocks and a toolkit of six connective reactions. Importantly, each individual scaffold has the ability to specifically target lead-like chemical space

Nosocomial or not? A combined epidemiological and genomic investigation to understand hospital-acquired COVID-19 infection on an elderly care ward.

BACKGROUND: COVID-19 has the potential to cause outbreaks in hospitals. Given the comorbid and elderly cohort of patients hospitalized, hospital-acquired COVID-19 infection is often fatal. Pathogen genome sequencing is becoming increasingly important in infection prevention and control (IPC). AIM: To inform the understanding of in-hospital SARS-CoV-2 transmission in order to improve IPC practices and to inform the future development of virological testing for IPC. METHODS: Patients detected COVID-19 positive by polymerase chain reaction on Ward A in April and May 2020 were included with contact tracing to identify other potential cases. Genome sequencing was undertaken for a subgroup of cases. Epidemiological, genomic, and cluster analyses were performed to describe the epidemiology and to identify factors contributing to the outbreak. FINDINGS: Fourteen cases were identified on Ward A. Contact tracing identified 16 further patient cases; in addition, eight healthcare workers (HCWs) were identified as being COVID-19 positive through a round of asymptomatic testing. Genome sequencing of 16 of these cases identified viral genomes differing by two single nucleotide polymorphisms or fewer, with further cluster analysis identifying two groups of infection (a five-person group and a six-person group). CONCLUSION: Despite the temporal relationship of cases, genome sequencing identified that not all cases shared transmission events. However, 11 samples were found to be closely related and these likely represented in-hospital transmission. This included three HCWs, thereby confirming transmission between patients and HCWs.S.R. and A.B. are part-funded from Research England’s Expanding Excellence in England (E3) Fund.

Scaling Up Malaria Control in Zambia: Progress and Impact 2005–2008

Zambia national survey, administrative, health facility, and special study data were used to assess progress and impact in national malaria control between 2000 and 2008. Zambia malaria financial support expanded from US$9 million in 2003 to US$ ~40 million in 2008. High malaria prevention coverage was achieved and extended to poor and rural areas. Increasing coverage was consistent in time and location with reductions in child (age 6–59 months) parasitemia and severe anemia (53% and 68% reductions, respectively, from 2006 to 2008) and with lower post-neonatal infant and 1–4 years of age child mortality (38% and 36% reductions between 2001/2 and 2007 survey estimates). Zambia has dramatically reduced malaria transmission, disease, and child mortality burden through rapid national scale-up of effective interventions. Sustained progress toward malaria elimination will require maintaining high prevention coverage and further reducing transmission by actively searching for and treating infected people who harbor malaria parasites

Value-Chain Wide Food Waste Management: A Systematic Literature Review

© 2019, Springer Nature Switzerland AG. The agriculture value chain, from farm to fork, has received enormous attention because of its key role in achieving United Nations Global Challenges Goals. Food waste occurs in many different forms and at all stages of the food value chain, it has become a worldwide issue that requires urgent actions. However, the management of food waste has been traditionally segmented and in an isolated manner. This paper reviews existing work that has been done on food waste management in literature by taking a holistic approach, in order to identify the causes of food waste, food waste prevention strategies, and elicit recommendations for future work. A five step systematic literature review has been adopted for a thorough examination of the existing research on the topic and new insights have been obtained. The findings suggest that the main sources of food waste include food overproduction and surplus, food waste caused by processing, logistical inconsistencies, and households. Main food waste prevention strategies have been revealed in this paper include policy solutions, packaging solutions, date-labelling solutions, logistics solutions, changing consumers’ behaviours, and reuse and redistribution solutions. Future research directions such as using value chain models to reduce food waste and forecasting food waste have been identified in this paper. This study makes a contribution to the extant literature in the field of food waste management by discovering main causes of food waste in the value chain and eliciting prevention strategies that can be used to reduce/eliminate relevant food waste
