Contributing Factors to Long Working Hours: Case Study of Waiters in Dire Dawa Administration  [PDF]
Gizachew Girma, Tadesse Moges
Beijing Law Review (BLR) , 2015, DOI: 10.4236/blr.2015.63017
Abstract: The need to create and maintain industrial peace, in one hand, protect the fragile interest of workers on the other side to boost economic development have been critical issues which have attained significant consideration from states. To that end, they introduced at international and national levels different set of legislations regulating employment relations. Among other things, working time limit has meticulously been introduced to safeguard the rights of workers, who are generally with the lesser bargaining power, and make the labor more productive. Ethiopia has accepted this notion of delimitating working hours, and adopted legislations. However, it has become a public secret that such rules have not been maintained in practice and that the enforcement mechanism appeared meager. Though researches have been made in different part of the world; in Ethiopia, particularly in Dire Dawa, the factors contributing for long working hours have not been addressed. There are, however, indicators that particularly waiters are working for longer hours than what the law stipulates. In a town dubbed as industrial corner, this factor should not be left unconsidered if the aspired objective of the labour regulation is really to be met. This research, hence, took the first step in studying the existence of this violation, and investigating the contributing factors. The data were collected through structured questionnaires and interviews, and samples were taken using stratified systematic sampling method. Data were analyzed through quantitative (descriptive analysis and logistic regression model) and qualitative techniques. Then, job insecurity, lack of legal awareness, culture of the work, salary, tips, dependents, and level of education have been found out to be contributing factors, and their level of significance has also been established. It has also revealed that the absence of strong enforcement mechanisms contributed for the apparent non-adherence to the rules so delimiting working hours.

Journal of Animal and Veterinary Advances , 2012, DOI: 10.3923/javaa.2011.1616.1622
Abstract: Among the animal diseases that require antibiotic treatment in dairy herds, mastitis is the commonest one. As a consequence antimicrobial resistance of mastitis pathogens has received recent attention. The purpose of this study was to describe and compare antimicrobial susceptibility of mastitis pathogens isolated on 322 local and crossbred lactating hand milked small holder cows. The major bacteria isolated in this study were Staphylococcus aureus (n = 27), Coagulase-Negative Staphylococci (CNS) (n = 51), Streptococcus agalactiae (n = 26), Streptococcus dysgalactiae (n = 23), Streptococcus uberis (n = 11), Micrococcus sp. (n = 12), Corynebacterium bovis (n = 4), Actinomyces pyogenes (n = 2), Bacillus cereus (n = 1) Escherichia coli (n = 7). Staphylococcus aureus was found to be highly sensitive to five of the antimicrobials tested where the bacteria had shown 100% susceptibility to kanamycin and sulfisoxazole. However, Coagulase negative staphylococci had revealed different levels susceptibility for only four of the nine antimicrobials tested. Streptococcus agalactiae was highly susceptible to sulfisoxazole (100%), clindamycin (100%) and susceptibility to streptomycin was 50%. Similarly, all other bacteria isolated demonstrated different level of susceptibility to the tested antimicrobials. In general it was found that sulfisoxazole was the most effective antibiotic where 91.07% of the total isolates were found susceptible followed by clindamycin and kanamycin with susceptibility of (89.28%) and (88.4%), respectively. The least effective antibiotics were streptomycin (45.5%), ampicillin (49.1%). Tetracycline, erythromycin, chloramphenicol and oxacllin have susceptibility of 65.2, 59.8, 64.3 and 58.04%, respectively.

Abstract:

Evaluating the outcomes of DOTS program is essential for recognizing and amending system failures before the incidence and proportion of resistant isolates rise. In this study, we seek to evaluate the impact of DOTS strategy on tuberculosis treatment success rate in Dabat, northwest Ethiopia. Medical records of 1305 pulmonary and extrapulmonary tuberculosis patients registered from 2007 to 2012 at two health centers in Dabat district, northwest Ethiopia, were reviewed. Treatment outcomes and forms of tuberculosis were assessed according to WHO guidelines. Descriptive analyses were performed using frequencies and percentages. Treatment success rate was observed in 1146 (87.8%) patients. Out of these, 534 (89.1%) of the males and 612 (86.7%) of the females were successfully treated. It was also true in 338 (87.8%) of the smear-positive pulmonary tuberculosis patients, 473 (85.7%) of the smear-negative pulmonary tuberculosis patients, and 335 (91.0%) of the extrapulmonary tuberculosis patients. In conclusion, treatment success rate in the current study was slightly higher than the WHO international updated target for the period 2011 to 2015. However, this doesn’t mean that there will be no need for further enhancement of supervision and monitoring techniques, strengthening counseling and health education programs, and improving the quality of laboratory diagnostic services.

Abstract: The study was undertaken in the northern periphery of the country, Tigray region, north-west Tigray zone, Tahitay Adiyabo district from February to March, 2017. For this study, four Kebeles were selected purposively based on the presence of two major community groups (Tigrayans and Kunama) and presence of camel species and other livestock species. Seventy-two (72) households per district, of which 38 households from two kebeles for Kunama community and 34 households from two kebeles for Tigrayan community groups were selected randomly. A software package of SAS (2008) was employed to generate descriptive statistics for qualitative and quantitative data. As the study revealed, three-fifth and two-fifth of the respondents in the study area were illiterate and attended primary education respectively. The two community groups were significantly (P < 0.05) different on educational status and Tigriyans respondents were more educated than the other counterpart. More than 2/3 children (7 - 17 years of age) of the respondents in the study area were attended school. Exceptionally, more than 75% of the children for Tigriyan community group in the district were attended school whereas 3/5th of Kunama community children were attended school education. Average family size per household in the study area was 6.22 ±

Abstract: Although its utilization is greatly disputed, ready-to-use therapeutic food has been started as clinical nutrition care and treatment for malnourished adult AIDS patients since 2011 in Amhara National Regional State. However, factors determining the intended outcome (weight gain) have not been properly investigated. The main objective of the study was to assess improvement in body mass index and to identify its determinant factors. A retrospective cohort study design was conducted. Cluster sampling was employed to select health facilities in which the service was provided in the region. Of the 44 health facilities, nine were selected using lottery method, and all patients receiving the care in these health institutions were included in the study. Using tailored structured checklist, data were collected, organized and cleaned. Using paired T-test existence of difference between the mean of body mass index at admission and at 3rd visit was measured. Finally analysis of association between some selected independent variables with the outcome variable was done using logistic regression model at 95% CI and p < 0.05. Of 431 study participants, 175 (40.6%) study participants’ body mass index was improved (≥18.5 kg/m2). Paired T-test revealed that there was a statistically significant difference between mean of body mass index at admission and at the 3rd visit. Good ready-to-use therapeutic food treatment adherence (AOR 11.145; 95% CI 6.556, 18.946), moderate acute malnutrition at admission (AOR 6.71; 95% CI 2.618, 17.195), good ART adherence (AOR 2.136; 95% CI, 1.269, 3.595) and being male (AOR 1.73; 95% CI 1.052, 2.850) have a statistically significant contribution for body mass index improvement. The study identifies factors that determine gain in body mass index among AIDS patients on ready-to-use therapeutic food. However, although the study revealed a statistically significant difference between body mass index during enrolment, and after three months, we disagreed with the right and left utilization of imported food because of lack of sustainability, and aid dependency. We rather recommend interventions that encourage households to produce food with similar outcomes from locally available food staff.

Abstract: Low flow analysis provides crucial information for the planning and design water resource development, risk assessment and environmental flow management. Understanding the low flow regimes and evaluating the magnitudes for incorporating in water resources management is vital for the countries like Ethiopia where demand for water is increasing. However, there were hardly enough studies in understanding the trends of low flow and frequency analysis. Therefore, this study focuses on evaluation of the trends in low flows and regional low flow analysis in the Blue Nile Basin, Ethiopia. In order to carry out the study, 15 river sub-basins in the Blue Nile Basin were selected based on the long term data availability and presence of quality of data. The 3-day sustained low flow (3d-slf), the 7-day sustained low flow (7d-slf) and the 14-day sustained low flow (14d-slf) models were used to extract the data from the daily time series stream data obtained from MoWIE. Trends in low flow were analyzed separately by using Mann-Kendall (MK) trend test. Low flow frequency analysis was used to estimate the long term low flow quantiles. In addition, regional analysis for estimating the quantiles for ungaged catchments was also developed based on the regional growth curve and catchment characteristic of drainage basins. The results indicated that 3d-slf, 7d-slf and 14d-slf models of low flow series indicated no significant difference for each station at 95% CI. Out of the 15 selected stations, 12 of stations have indicated decreasing; two stations indicated increasing and remaining one station with no trend. Mainly decreasing trend was associated with the land cover and climate change which results in increasing runoff and evapotranspiration respectively. Weibull distribution—GEV and LGN was found best fit based on the L-Moment Ratio Diagram (L-MRD). Hence quantile estimations have indicated diminishing magnitudes of low flow quintiles for 2 - 500 years return periods. Regional low frequency analysis has provided a very good relationship between discharge and catchment characteristics with an R2 of 0.72. Where area (A) and rainfall (R) followed by slope were found sensitive to compute in developing the regional region equations between mean low flows and the physiographic data. This study indicated that there needs to be a new water management scenario and adaptation mechanism of climate change and land use land cover dynamics for utilizing water resource in the Blue Nile Basin.

Natural Resources (NR) , 2014, DOI: 10.4236/nr.2014.511054
Abstract:
Soil degradation in the form of soil erosion is a serious and continuous environmental problem in Jabi Tehinan Woreda. Uncontrolled land use, deforestation, over cultivation, overgrazing and exploitation of biomass for firewood, construction and other household uses due to increasing population ultimately lead to severe soil erosion. The impact of natural hazards like erosion can be minimized and ultimately controlled by disaster preparedness maps. Therefore, the overall objective of this paper is to quantify and map an estimated soil loss by examining different topographic and anthropogenic factors for the planning and implementations of sustainable soil conservation and management system in the study area. This study had integrated Geographic Information System (GIS), Remote Sensing (RS) and Multi-Criteria Evaluation (MCE) techniques to quantify and map erosion vulnerable areas using RUSLE model. Slope gradient, slope length, soil type, soil conservations techniques, cover management and rainfall variables were used as input model parameters/variables. The data had been collected and analyzed from different land sat imageries, SRTM data, topomaps and point interpolations of primary data. Finally, the aggregated effects of all parameters had been analyzed and soil loss from the area was calculated using RUSEL models. After analyzing all model parameters, areas in steeper slope with Lithosols, Eutric Nitosols, Orthic Luvisols, croplands, bare lands and river banks have been identified as the most erosion vulnerable areas. Quantitatively, an estimated annual soil loss in Jabi Tehinan Woreda ranges from nearly 0 in south and central parts of the area to 504.6 t/ha/yr in steeply sloping mountainous areas of the north and north-eastern parts of the catchments.

Abstract: This work focuses on the theoretical investigation of the coexistence of superconductivity and ferromagnetism in the superconducting HoMo6S8. By developing a model Hamiltonian for the system and using the Green’s function formalism and equation of motion method, we have obtained expressions for superconducting transition temperature (Tc), magnetic order temperature (Tm), superconductivity order parameter (D) and magnetic order parameter (η). By employing the experimental and theoretical values of the parameters in the obtained expressions, phase diagrams of energy gap parameter versus transition temperature, superconducting transition temperature versus magnetic order parameter and magnetic order temperature versus magnetic order parameter are plotted separately. By combining the phase diagrams of superconducting transition temperature versus magnetic order parameter and magnetic order temperature versus magnetic order parameter, we have demonstrated the possible coexistence of superconductivity and ferromagnetism in superconducting HoMo6S8.<
A Concise Review of Amyloidosis in Animals

Veterinary Medicine International , 2012, DOI: 10.1155/2012/427296
Abstract: Amyloidosis refers to a group of protein misfolding diseases characterized by deposition of a particular amyloid protein in various organs and tissues of animals and humans. Various types and clinical forms of amyloidosis, in which the pathology and pathogenesis is diverse depending upon the underlying causes and species affected, are reported in domestic and wild animals. The clinical findings are also quite variable consequent to the variation of the tissues and organs involved and the extent of functional disruption of the affected organs in various animal species. The affected organs may be enlarged and exhibit variable pallor grossly, or the amyloid deposit may be discernible only after microscopic examination of the affected tissues. Amyloid appears as a pale eosinophilic homogenous extracellular deposit in tissues. However, microscopic examination and Congo red staining with green birefringence under polarized light are needed to confirm amyloid and differentiate it from other apparently similar extracellular deposits such as collagen and fibrin. Identifying the type of amyloid deposit needs immunohistochemical staining, ultrastructural characterization of the amyloid fibril, and if feasible also genetic studies of the involved species for clinical and prognostic purposes. This paper provides a concise review of the occurrence of amyloidosis in domestic and wild animals. 1. Introduction Amyloid is a pathologic proteinaceous substance deposited between cells in various tissues and organs of the body in a wide variety of clinical settings [1]. Although there are other components present in the deposit, the amyloid protein fibril is the main component of the amyloid substance. The deposit differs in protein composition depending upon the types of amyloidosis and the different clinical forms. Each clinical entity of amyloidosis may be manifested by a distinct clinical form with chemically specific amyloid fibril protein. This indicates that amyloid is a biochemically heterogeneous substance, although there are similarities in properties and staining characteristics. 1.1. Nomenclature and Classification of Amyloidosis According to the WHO-IUIS Nomenclature Subcommittee [2] on the nomenclature of amyloid and amyloidosis, amyloid and amyloidosis are classified based on the amyloid fibril protein, followed by a designation of the fibril protein precursor. The capital letter A for amyloid is followed by the protein designation in abbreviated form. For example AL-amyloid refers to the amyloid derived from immunoglobulin light chain and may be seen in
