Information architecture for effective Workload Control: an insight from a successful implementation
The implementation of Workload Control (WLC), a Production Planning and Control concept uniquely designed for Make-To-Order companies, has been a constant challenge. Scholars argued that WLC is largely developed through simulations of well-defined environments while much more complex circumstances (e.g. information availability) have emerged in field research. A recent trend of WLC research is to improve the practical applicability of the concept, where empirical evidence is essential. However, success in WLC implementation remains impeded. The availability of data has been a significant area that frustrates the implementation process. While there is a tendency to simplify data requirements in recent WLC theory development, it is important to understand and maintain the information that is essential for the concept to be effective. For the first time in the field, this paper details the information architecture for WLC. Key informational entities of relevance to the input/output control functions in WLC as well as performance measurement are discussed based on evidence from a successful implementation. The paper not only sheds light for practitioners on how to construct an information system that facilitates successful WLC implementation but also has implications for future development of WLC mechanisms coping with information uncertainties in practice
Capacity development for health research in Africa: experiences managing the African Doctoral Dissertation Research Fellowship Program
Africa's progress depends on her capacity to generate, adapt, and use scientific knowledge to meet regional health and development needs. Yet, Africa's higher education institutions that are mandated to foster this capacity lack adequate resources to generate and apply knowledge, raising the need for innovative approaches to enhance research capacity. In this paper, we describe a newly-developed program to support PhD research in health and population sciences at African universities, the African Doctoral Dissertation Research Fellowship (ADDRF) Program. We also share our experiences implementing the program. As health research capacity-strengthening in Africa continues to attract attention and as the need for such programs to be African-led is emphasized, our experiences in developing and implementing the ADDRF offer invaluable lessons to other institutions undertaking similar initiatives
Transgressing the moral economy: Wheelerism and management of the nationalised coal industry in Scotland
This article illuminates the links between managerial style and political economy in post-1945 Britain, and explores the origins of the 1984â1985 miners' strike, by examining in longer historical context the abrasive attitudes and policies of Albert Wheeler, Scottish Area Director of the National Coal Board (NCB). Wheeler built on an earlier emphasis on production and economic criteria, and his micro-management reflected pre-existing centralising tendencies in the industries. But he was innovative in one crucial aspect, transgressing the moral economy of the Scottish coalfield, which emphasised the value of economic security and changes by joint industrial agreement
The Current State of Performance Appraisal Research and Practice: Concerns, Directions, and Implications
On the surface, it is not readily apparent how some performance appraisal research issues inform performance appraisal practice. Because performance appraisal is an applied topic, it is useful to periodically consider the current state of performance research and its relation to performance appraisal practice. This review examines the performance appraisal literature published in both academic and practitioner outlets between 1985 and 1990, briefly discusses the current state of performance appraisal practice, highlights the juxtaposition of research and practice, and suggests directions for further research
Faktori rizika od karcinoma larinksa u Crnoj Gori
Laryngeal cancer is the most common head and neck cancer. There might be many risk factors for laryngeal cancer. Smoking, especially cigarette smoking and alcohol are indisputable risk factors. The authors of this paper assessed the presumed risk factors in order to identify possible aetiological agents of the disease. A hospital-based case-control study was conducted. The study group consisted of 108 histologically verified laryngeal cancer patients and 108 hospital controls matched by sex, age (±3 years) and place of residence. Laryngeal cancer patients and controls were interviewed during their hospital stay using a structured questionnaire. According to multiple logistic regression analysis six variables were independently related to laryngeal cancer: hard liquor consumption (Odd Ratio /OR/=2.93, Confidence Interval /CI/ 95 % = 1.17 to 7.31), consumption more than 2 alcoholic drinks per day (OR=4.96, CI 95 % = 2.04 to12.04), cigarette smoking for more than 40 years (OR=4.32, CI 95 % = 1.69 to 11.06), smoking more than 30 cigarettes per day (OR=4.24, CI 95 % = 1.75 to 10.27), coffee consumption more than 5 cups per day (OR=4.52, CI 95 % = 1.01 to 20.12) and carbonated beverage consumption (OR=0.38, CI 95 %= 0.16 to 0.92). The great majority of laryngeal cancers could be prevented by eliminating tobacco smoking and alcohol consumption.Maligni tumori larinksa najÄeĆĄÄi su tumori glave i vrata. Glavni faktori rizika od razvoja malignih tumora grkljana su puĆĄenje i konzumiranje alkoholnih piÄa. Cilj rada bio je ispitivanje potencijalnih faktora rizika od nastanka malignih tumora larinksa. Sprovedena je studija sluÄaj-kontrola. Studijsku grupu Äinilo je 108 pacijenata s histoloĆĄki verificiranim rakom larinksa i 108 kontrola individualno izjednaÄenih po spolu, dobi (± 3 godine) i mjestu stanovanja. Svi ispitanici su anketirani ciljanim epidemioloĆĄkim upitnikom a u analizi podataka koriĆĄtena je multivarijantna logistiÄka regresijska analiza. KoristeÄi se multivarijantnom logistiÄkom regresijskom analizom, statistiÄki znaÄajnu povezanost s rakom larinksa dobili smo za sljedeÄe varijable: konzumiranje ĆŸestokih piÄa (omjer izgleda /OR/=2.93, interval pouzdanosti /CI/ 95 % = 1.17 do 7.31), konzumiranje viĆĄe od 2 alkoholna piÄa na dan (OR = 4.96, CI 95 % = 2.04 do 12.04), konzumiranje cigareta duĆŸe od 40 godina (OR = 4.32, CI 95 % = 1.69 do 11.06), konzumiranje viĆĄe od 30 cigareta na dan (OR = 4.24, CI 95 % = 1.75 do 10.27), konzumiranje viĆĄe od 5 ĆĄalica kave na dan (OR = 4.52, CI 95 % = 1.01 do 20.12) i konzumiranje gaziranih piÄa (OR = 0.38, CI 95 % = 0.16 do 0.92). Obolijevanje zbog malignih tumora larinksa moglo bi se znaÄajno smanjiti prestankom konzumiranja duhana i alkohola

Awareness and knowledge of sexually transmitted diseases (STDs) among school-going adolescents in Europe: a systematic review of published literature
Samkange-Zeeb FN, Spallek L, Zeeb H. Awareness and knowledge of sexually transmitted diseases (STDs) among school-going adolescents in Europe: a systematic review of published literature. BMC public health. 2011;11(1): 727.BACKGROUND: Sexually transmitted diseases (STDs) are a major health problem affecting mostly young people, not only in developing, but also in developed countries.We conducted this systematic review to determine awareness and knowledge of school-going male and female adolescents in Europe of STDs and if possible, how they perceive their own risk of contracting an STD. Results of this review can help point out areas where STD risk communication for adolescents needs to be improved. METHODS: Using various combinations of the terms "STD", "HIV", "HPV", "Chlamydia", "Syphilis", "Gonorrhoea", "herpes", "hepatitis B", "knowledge", "awareness", and "adolescents", we searched for literature published in the PubMed database from 01.01.1990 up to 31.12.2010. Studies were selected if they reported on the awareness and/or knowledge of one or more STD among school-attending adolescents in a European country and were published in English or German. Reference lists of selected publications were screened for further publications of interest. Information from included studies was systematically extracted and evaluated. RESULTS: A total of 15 studies were included in the review. All were cross-sectional surveys conducted among school-attending adolescents aged 13 to 20 years. Generally, awareness and knowledge varied among the adolescents depending on gender.Six STDs were focussed on in the studies included in the review, with awareness and knowledge being assessed in depth mainly for HIV/AIDS and HPV, and to some extent for chlamydia. For syphilis, gonorrhoea and herpes only awareness was assessed. Awareness was generally high for HIV/AIDS (above 90%) and low for HPV (range 5.4%-66%). Despite knowing that use of condoms helps protect against contracting an STD, some adolescents still regard condoms primarily as an interim method of contraception before using the pill. CONCLUSION: In general, the studies reported low levels of awareness and knowledge of sexually transmitted diseases, with the exception of HIV/AIDS. Although, as shown by some of the findings on condom use, knowledge does not always translate into behaviour change, adolescents' sex education is important for STD prevention, and the school setting plays an important role. Beyond HIV/AIDS, attention should be paid to infections such as chlamydia, gonorrhoea and syphilis
