    Purpose: To survey the level of BSE practice among female nursing students in Aceh, and the degree of self-efficacy in those who did practice it.Method: Seventy-six nursing students from the Public Nursing College, Syiah Kuala University in Aceh who met the inclusion criteria were recruited. Stratified proportionate random sampling was used to determine the required number of first, second, and third year students. BSE self-efficacy of the students was measured by the BSE Self-Efficacy Questionnaire which was modified from an existing tool developed by Khatun (2010). In addition, the students' doing BSE or not was measured by BSE Practice Questionnaire which was developed by the researcher. The data were analyzed by using descriptive statistics.Result: Only 39.5% of the students practiced BSE with more than half of the students saying they did not practice BSE (60.5%). The main factors that influenced the students' performing BSE were not having a family history of breast cancer, single, and no history of breast illness. Among the thirty students who practiced BSE, most of them did not practice it routinely (70%), nor at the correct time (86.7%), and their confidence in performing BSE was at a moderate level overall, with a high level for BSE procedural efficacy and moderate level for barrier management efficacy.Conclusion: A majority of the Acehnese nursing students did not practice BSE, and those who did had only a moderate level of BSE self-efficacy. Therefore, the results of this study suggest emphasizing the need to teach nursing students about BSE in their undergraduate courses, with future follow-up research regarding the success of the educational program

    Purpose: To develop the educational program which is appropriate with Islamic culture in order to enhance BSE self-efficacy of nursing students and thus promote BSE practice. Method: This study is a development research study which is consisting of three phases including: 1) reviewing several existing BSE educational programs; 2) program design based on SCT and Islamic culture; and 3) program validation by three experts. Result: Based on previous studies, the most appropriate theory to enhance self-efficacy was Social Cognitive Theory (SCT) because this theory provides several strategies to increase the self-efficacy. Further, the program that used Islamic culture was more appropriate to increase BSE practice among Muslim women. As a result, the newly developed program was developed used SCT and Islamic culture. This program was comprised of four sessions including: 1) exploring Islamic mandate on prevention and individual responsibility in health promotion, and culture-related beliefs toward BSE, 2) health education by conducting lecturing session and watching a video about BSE procedures, 3) BSE training activities including BSE demonstration and return demonstration, 4) follow-up by conducting a meeting. Conclusion: The cultural-based educational program for enhancing BSE self-efficacy and promoting BSE is a program using multifaceted methods. It designed based on a review of the literature from previous studies and were supported by research findings on experimental studies in other population

    Extending backcalculation to analyse BSE data.

    We review the origins of backcalculation (or back projection) methods developed for the analysis of AIDS (acquired immunodeficiency syndrome) incidence data. These techniques have been used extensively for >15 years to deconvolute clinical case incidence, given knowledge of the incubation period distribution, to obtain estimates of past HIV (human immunodeficiency virus) infection incidence and short-term predictions of future AIDS incidence. Adaptations required for the analysis of bovine spongiform encephalopathy (BSE) incidence included: stratification of BSE incidence by age as well as birth cohort; allowance for incomplete survival between infection and the onset of clinical signs of disease; and decomposition of the age- and time-related infection incidence into a time-dependent feed risk component and an age-dependent exposure/susceptibility function. The most recent methodological developments focus on the incorporation of data from clinically unaffected cattle screened using recently developed tests for preclinical BSE infection. Backcalculation-based predictions of future BSE incidence obtained since 1996 are examined. Finally, future directions of epidemiological analysis of BSE epidemics are discussed taking into account ongoing developments in the science of BSE and possible changes in BSE-related policies

    BACKGROUND: The variability in the clinical or pathological presentation of transmissible spongiform encephalopathies (TSEs) in sheep, such as scrapie and bovine spongiform encephalopathy (BSE), has been attributed to prion protein genotype, strain, breed, clinical duration, dose, route and type of inoculum and the age at infection. The study aimed to describe the clinical signs in sheep infected with the BSE agent throughout its clinical course to determine whether the clinical signs were as variable as described for classical scrapie in sheep. The clinical signs were compared to BSE-negative sheep to assess if disease-specific clinical markers exist. RESULTS: Forty-seven (34%) of 139 sheep, which comprised 123 challenged sheep and 16 undosed controls, were positive for BSE. Affected sheep belonged to five different breeds and three different genotypes (ARQ/ARQ, VRQ/VRQ and AHQ/AHQ). None of the controls or BSE exposed sheep with ARR alleles were positive. Pruritus was present in 41 (87%) BSE positive sheep; the remaining six were judged to be pre-clinically infected. Testing of the response to scratching along the dorsum of a sheep proved to be a good indicator of clinical disease with a test sensitivity of 85% and specificity of 98% and usually coincided with weight loss. Clinical signs that were displayed significantly earlier in BSE positive cases compared to negative cases were behavioural changes, pruritic behaviour, a positive scratch test, alopecia, skin lesions, teeth grinding, tremor, ataxia, loss of weight and loss of body condition. The frequency and severity of each specific clinical sign usually increased with the progression of disease over a period of 16-20 weeks. CONCLUSION: Our results suggest that BSE in sheep presents with relatively uniform clinical signs, with pruritus of increased severity and abnormalities in behaviour or movement as the disease progressed. Based on the studied sheep, these clinical features appear to be independent of breed, affected genotype, dose, route of inoculation and whether BSE was passed into sheep from cattle or from other sheep, suggesting that the clinical phenotype of BSE is influenced by the TSE strain more than by other factors. The clinical phenotype of BSE in the genotypes and breed studied was indistinguishable from that described for classical scrapie cases

    Measuring the Impact of a BSE Announcement on U.S. Retail Beef Sales: A Time-Series Analysis

    Get PDF
    On December 23, 2003, Agriculture Secretary Ann M. Veneman announced that the United States Department of Agriculture had diagnosed the first U.S. case of bovine spongiform encephalopathy (BSE), commonly known as “mad cow disease.†This study uses supermarket sales data to analyze the effect of the BSE announcement on U.S. retail beef sales, finding a statistically significant disruption of sales. In addition, we develop a forecast of retail beef sales revenues in the hypothetical absence of BSE. The forecast implies that the BSE announcement may have reduced domestic retail beef revenues in excess of $11 billion in the post-BSE period.ARIMA models, BSE, mad cow disease, U.S. retail beef sales, Health Economics and Policy, Livestock Production/Industries,

    A systematic benchmark of the ab initio Bethe-Salpeter equation approach for low-lying optical excitations of small organic molecules

    Full text link
    The predictive power of the ab initio Bethe-Salpeter equation (BSE) approach, rigorously based on many-body Green's function theory but incorporating information from density functional theory, has already been demonstrated for the optical gaps and spectra of solid-state systems. Interest in photoactive hybrid organic/inorganic systems has recently increased, and so has the use of the BSE for computing neutral excitations of organic molecules. However, no systematic benchmarks of the BSE for neutral electronic excitations of organic molecules exist. Here, we study the performance of the BSE for the 28 small molecules in Thiel's widely-used time-dependent density functional theory benchmark set [M. Schreiber et al. J. Chem. Phys. 128, 134110 (2008)]. We observe that the BSE produces results that depend critically on the mean-field starting point employed in the perturbative approach. We find that this starting point dependence is mainly introduced through the quasiparticle energies obtained at the intermediate GW step, and that with a judicious choice of starting mean-field, singlet excitation energies obtained from BSE are in excellent quantitative agreement with higher-level wavefunction methods. The quality of the triplet excitations is slightly less satisfactory

    Suppose that AA is a semi-simple and commutative Banach algebra. In this paper we try to characterize the character space of the Banach algebra CBSE(Δ(A))C_{\rm{BSE}}(\Delta(A)) consisting of all BSE-functions on Δ(A)\Delta(A) where Δ(A)\Delta(A) denotes the character space of AA. Indeed, in the case that A=C0(X)A=C_0(X) where XX is a non-empty locally compact Hausdroff space, we give a complete characterization of Δ(CBSE(Δ(A)))\Delta(C_{\rm{BSE}}(\Delta(A))) and in the general case we give a partial answer. Also, using the Fourier algebra, we show that CBSE(Δ(A))C_{\rm{BSE}}(\Delta(A)) is not a CC^*-algebra in general. Finally for some subsets EE of AA^*, we define the subspace of BSE-like functions on Δ(A)E\Delta(A)\cup E and give a nice application of this space related to Goldstine's theorem.Comment: 8 pages, To appear in "Sahand Communications in Mathematical Analysis

    BioCloud Search EnGene: Surfing Biological Data on the Cloud

    The massive production and spread of biomedical data around the web introduces new challenges related to identify computational approaches for providing quality search and browsing of web resources. This papers presents BioCloud Search EnGene (BSE), a cloud application that facilitates searching and integration of the many layers of biological information offered by public large-scale genomic repositories. Grounding on the concept of dataspace, BSE is built on top of a cloud platform that severely curtails issues associated with scalability and performance. Like popular online gene portals, BSE adopts a gene-centric approach: researchers can find their information of interest by means of a simple “Google-like” query interface that accepts standard gene identification as keywords. We present BSE architecture and functionality and discuss how our strategies contribute to successfully tackle big data problems in querying gene-based web resources.

    BSE and the Dynamics of Beef Consumption: Influences of Habit and Trust

    This study relates habit persistence and trust to recurring food safety incidents in the context of a series of three BSE incidents in Canada. We examined the dynamics of monthly beef expenditure shares of a sample of Canadian households for monthly time periods during year 2002 through 2005 using micro level panel data which followed meat expenditures by Canadian households before and after the first three BSE cases which were discovered in 2003 and 2005. Our results suggest that households’ reactions to the first three BSE events followed a similar general pattern: households reduced beef purchase expenditures following the discovery of BSE but these expenditures subsequently recovered, suggesting that concern diminished over time. Following the first BSE event, we identified an immediate negative impact on beef expenditures. However, in the case of the second and third BSE events, this negative impact was not evident until two months after these BSE announcements. In each of the three cases, the negative impact of BSE on beef purchase expenditures was limited to no more than four months. Assessment of how habit persistence affected beef expenditures indicates that this influence limited households reductions of beef purchases following the BSE events, but the effects of habit diminished subsequent to the initial event. Regarding the role of trust in shaping households’ reactions to BSE, we found that households’ respondents whose answers to standardized questions suggest that they are not “trusting” individuals were more sensitive to the food risks identified by the BSE events.BSE, habit, and trust, Demand and Price Analysis, Food Consumption/Nutrition/Food Safety,
