SOME STRENGTHS AND WEAKNESSES OF TRADITIONAL ACADEMIC ANTHRO-SOCIOLOGICAL RESEARCH

ABSTRACTAnalysis of this monograph, and the research project from which it stems offers the basis for a discussion of some strengths and weaknesses of traditional academic anthro-sociological research. Such strengths are to be found in (small scale) studies of community value systems. The weaknesses arise when such studies are conducted either in isolation from wider national frame works or -as in this case -inserted into them almost at random. The volume contains many conceptual and technical errors. These fall, especially, in three categories: 1. ethnicity taken as a unique determinant of social consciousness; 2. conceptual and technical confusion over the nature of health service development and utilization; and, 3. failure to recognize (much less analyze) the fact of the Ethiopian revolution and its likely effects on the people and issues under discussion. Most of the specific recommendations of the research project are found to be ill conceived and often in gross error. Finally, the monograph demonstrates the difficulty of understanding the processes of social change through analyses based primary on small communities divorced from -or improperly located within -their wider social context. This difficulty is especially clearly demonstrated in this study as it was carried out at a special moment of dynamic revolutionary history, which moment the monograph's authors appear not to have noticed

Angularity determination of abrasive powders

Abstract The influence of particle shape on abrasive processes is not well understood, but the angularity of the abrasive powders is assumed to be an important parameter. For that purpose an automatic angularity determination program was developed, based on the curvature of a twodimensional projection of a particle. This paper describes the algorithm used and the preliminary measurements and results. Aspects still open for improvement are: filtering of the pixel noise, reproducibility and the discriminative power of the algorithm. The most important question to answer was: "'What is a corrter?". In fairness it should be concluded that this question can only be answered successfully in combination with a particular application

ETHNOMEDICINAL STUDY OF UBAR KAMPUNG FOR DIABETES MELLITUS: INDIGENOUS KNOWLEDGE, BELIEF, AND PRACTICE OF MEDICINAL, AROMATIC, AND COSMETIC (MAC) PLANTS IN SUNDA REGION, WEST JAVA, INDONESIA

Objective: Over the past several decades, ethnobotany and ethnomedicine have been considered as a more appropriate interdisciplinary approach to drug discovery involving interdisciplinary collaboration. Several studies on ethnomedicine and ethnobotany worldwide have shown that diabetes mellitus has been recognised by the traditional healer as a pathological condition which can be treated with specific medicinal plants. The starting point in an ethno-directed search for anti-diabetic plants is the identification of plant species used by local healers for this purpose. This study aims to document medicinal plants used by local communities for the treatment of diabetes mellitus. Methods: This ethnographical study highlights the emic point of the local people to documents knowledge, belief, and practice of ubar kampung in Sunda Region. Results: The results of this study reveals 20 of most frequently used of medicinal, aromatic, and cosmetic plants by people in Sundanese community. The majority of plant species used for the treatment of diabetes mellitus belong to the families of Asteraceae (2 species), Lauraceae (2 species), and Liliaceae (2 species). Conclusion: Most of the medicinal plants reported in the research area are already publicly acknowledged for their medicinal properties, indicating that their pharmacological activities have been studied in different areas. Medicinal plants such Syzygium polyanthum, Moringa oleifera, Swietenia mahagoni, Allium sativum, and Cinnammomum burmanni have been widely used in several regions by various ethnic groups. Leaves are the most frequently used plant part. In general, infusion and decoction are the most common plant preparation methods in the research area

Microfabrication of Microchannels for Fuel Cell Plates

Portable electronic devices such as notebook computers, PDAs, cellular phones, etc., are being widely used, and they increasingly need cheap, efficient, and lightweight power sources. Fuel cells have been proposed as possible power sources to address issues that involve energy production and the environment. In particular, a small type of fuel-cell system is known to be suitable for portable electronic devices. The development of micro fuel cell systems can be achieved by the application of microchannel technology. In this study, the conventional method of chemical etching and the mechanical machining method of micro end milling were used for the microfabrication of microchannel for fuel cell separators. The two methods were compared in terms of their performance in the fabrication with regards to dimensional errors, flatness, straightness, and surface roughness. Following microchannel fabrication, the powder blasting technique is introduced to improve the coating performance of the catalyst on the surface of the microchannel. Experimental results show that end milling can remarkably increase the fabrication performance and that surface treatment by powder blasting can improve the performance of catalyst coating

Prescribing Errors With Low-Molecular-Weight Heparins

BACKGROUND: Low-molecular-weight heparins (LMWHs) are used in the prevention and treatment of venous thromboembolism (VTE). Bleeding is the primary major complication of LMWH therapy, which is associated with dose. The administration of appropriate dosages of LMWHs depends on the patient's risk of VTE, risk of bleeding, bodyweight, and renal function. Therefore, LMWH prescribing is prone to errors. However, no earlier study has explored the frequency of prescribing errors with LMWH. PURPOSE: The aim of the study was to determine the frequency and determinants of in-hospital LMWH-prescribing errors. METHODS: A cross-sectional study was conducted to examine the frequency and determinants of LMWH prescribing errors between April and August 2014. We randomly selected 500 patients 18 years and older with at least one LMWH prescription during inpatient hospitalization. A prescribing error was a deviation from the internal hospital guidelines. Logistic regression estimated determinants of prescribing error. RESULTS: A prescribing error was present with 34% of all LMWH users. The most frequently recorded error was a dose that was not adjusted to body weight and/or renal function (85%). Prophylactic LMWH prescribing in medical wards was associated with a higher risk of prescribing error as compared with surgical wards. CONCLUSIONS: The frequency of prescribing errors was 34% in a tertiary care hospital. Being a patient with prophylactic LMWH use on a medical ward is a determinant for LMWH prescribing error. Interventions that will lead to better electronic recording of body weight and more awareness among medical doctors may reduce the total number of prescribing errors

Mammography screening: views from women and primary care physicians in Crete

Background: Breast cancer is the most commonly diagnosed cancer among women and a leading cause of death from cancer in women in Europe. Although breast cancer incidence is on the rise worldwide, breast cancer mortality over the past 25 years has been stable or decreasing in some countries and a fall in breast cancer mortality rates in most European countries in the 1990s was reported by several studies, in contrast, in Greece have not reported these favourable trends. In Greece, the age-standardised incidence and mortality rate for breast cancer per 100.000 in 2006 was 81,8 and 21,7 and although it is lower than most other countries in Europe, the fall in breast cancer mortality that observed has not been as great as in other European countries. There is no national strategy for screening in this country. This study reports on the use of mammography among middleaged women in rural Crete and investigates barriers to mammography screening encountered by women and their primary care physicians. Methods: Design: Semi-structured individual interviews. Setting and participants: Thirty women between 45–65 years of age, with a mean age of 54,6 years, and standard deviation 6,8 from rural areas of Crete and 28 qualified primary care physicians, with a mean age of 44,7 years and standard deviation 7,0 serving this rural population. Main outcome measure: Qualitative thematic analysis. Results: Most women identified several reasons for not using mammography. These included poor knowledge of the benefits and indications for mammography screening, fear of pain during the procedure, fear of a serious diagnosis, embarrassment, stress while anticipating the results, cost and lack of physician recommendation. Physicians identified difficulties in scheduling an appointment as one reason women did not use mammography and both women and physicians identified distance from the screening site, transportation problems and the absence of symptoms as reasons for non-use. Conclusion: Women are inhibited from participating in mammography screening in rural Crete. The provision of more accessible screening services may improve this. However physician recommendation is important in overcoming women's inhibitions. Primary care physicians serving rural areas need to be aware of barriers preventing women from attending mammography screening and provide women with information and advice in a sensitive way so women can make informed decisions regarding breast caner screening
