This paper focuses mainly on marriage, family and kinship. Anthropologists traditionally have a strong interest in families, along with larger systems of kinship and marriage. These terms are core in anthropology discipline. They are socially constructed and have different meanings across culture. All these three concepts are discussed in this paper accordingly with necessary examples.
In order to investigate the effect of temperature of absorption liquid and exhaust temperature of diesel engine on decarbonization efficiency of marine decarbonization tower, the effect of temperature on carbon dioxide absorption efficiency in ship exhaust was studied by means of theory, experiment and simulation. Because of the particularity of the experiment, three exhaust temperatures of 25, 45 and 65 degrees celsius are mainly set up in this paper. The relevant experimental data are collected and analyzed under idle speed, 25% load condition, 50% load condition and 75% load condition, respectively. The experimental results show that under the same load, when the exhaust gas temperature increases, the absorption efficiency shows a downward trend. and the experimental exhaust gas temperature was simulated by Aspen plus software from 35 to 200 degrees celsius respectively. the simulation results show that the absorptivity decreases with the increase of temperature, and the simulation results are consistent with the experimental results, which has a certain reference for the design and operation parameters selection of marine decarburization tower.
Parental involvement (PI) in the education of children is not a recent phenomenon. PI has become an established feature of education policies across the developed world. The study set to establish factors that may make parents choose not to participate in education process or unable to become more involved. The study was grounded in Epstein’s overlapping spheres of influence theory. A qualitative case study was employed. Purposive sampling was used to select (4) schools and (40) participants in Alefa district, Central Gondar Zone, Ethiopia. Findings revealed that the economic status and level of education of parents have a significant effect on children’s education. It also emerged that parents are more likely to be involved when teachers’ perceptions about role of parents are positive. The study established that PI is also influenced by age of children. The study recommends that parents be helped to appreciate the benefits of parental involvement in the learning of their children. Workshops should be established to develop the relationship between parents and their children.
The purpose of this study was to investigate teaching –learning roles of instructional leadership in the full cycle primary schools of Chilga woreda, Central Gondar Zone. To meet the objectives of the sudy descriptive survey design was employed. Teachers, principals, supervisors, and woreda education officers were used as primary sources of data, and annual reports and different document records used as secondary sources of data. Regarding to sampling, teachers were selected by lottery method, and principals, supervisors and woreda education officers were selected by purposive sampling method. Questionnaires, interview and document analysis were used as data collection instruments and the data were analyzed through mean, standard deviation and compare means. The finding of this study revealed that almost all instructional leaders were subject specialists, lacks skill and training, and lacks commitment and moral to accomplish their tasks and severe shortage of finance. Based on the findings, it was concluded that: Schools were to some extent incapable of enhancing teachers’ professional skill development and improving the quality of education. The stated vision and defined mission in the school did not command the ownership of its potential stakeholders since it was not supported by its potential stakeholders. Instructional leaders did not possess the required skill, knowledge and attitude through training. In line with the above findings and conclusions it was recommended that: to equip instructional leaderships with necessary knowledge, attitude and skills the Region, Zone and Woreda Education Officials may arrange workshops, seminars, short and long term training in collaboration with different universities, colleges and NGO’s and schools need to think of their own income generating sources on top of government budget through improving their relationship with local NGO’s and school communities by preparing project proposal and submit to international donors.
Advantages and Disadvantages of Neoliberalism/Neoliberal Economic policy in General and the case of Ethiopia in Particular
Introduction: The same dictionary describes Neoliberalism also, which is said to be “a modified or revived form of traditional liberalism, [especially] one based on belief in free market capitalism and the rights of the individual” (Oxford English Dictionary 1989a). Currently because of the age of globalization, the world is becoming to be conceived as a village. One of the major projects of globalization is the integration of the political economy of the less developed regions in to the global political economic order. Accordingly, during the past few decades the continent of Africa has been trying to integrate itself in to the international political economy either forcefully or by consent. Generally, it is obvious that the main theme of neoliberalist is a fundamentalist view of “leaving everything for the market and the private investors with no interference of the government on the economy except keeping law and order. Historical Background of Neoliberalism: Now a day, world is integrated and became a village. The driving force of this integration is the ideology of Neoliberalism. Under this integration states are recommended or forced to open up their markets to foreign companies competitions, to minimize the role of the government in the economy including minimizing the government expense for social security and social goods, to create fertile grounds for the market to be the only means to distribute the wealth of a nation and the prices of goods and services to be determined based on the principles of demand and supply (Tewdros, 2011: iii). According to Saad-Filho and Johnston (2005:1), “we live in the age of neoliberalism”. The policy of “neoliberalism can be traced to the late 1960‟s and early 1970s as a particular strategic response to the crisis of Keynesianism” (Fassil, 2008:506). It was started in 1960s by a group of professors from…
As we know a successful endodontic treatment requires a thorough knowledge of internal and external tooth morphology, correct interpretation of radiographs, and adequate access to and exploration of the tooth’s interior. This case report presents the endodontic therapy of rare case of Radix Entomolaris in mandibular first molar with three roots( mesial, distal and distolingual) and five canals namely mesiobuccal, mesiolingual, distobuccal, first and second distolingual.
Productivity and Grain quality of Holker, Ibon and Franka malt barley (hordeum vulgare l.) varieties to the rate of nitrogen fertilizer
A field experiment were conducted during the 2018 cropping season at central highlands of Ethiopia to determine grain quality and yield response of malt barley (Hordeum vulgare L.) varieties to different rate of nitrogen fertilizer. The experiment was laid in a split plot design; Nitrogen rate as main plot and varieties as subplot with three replications. Phonological traits, Grain quality parameters and yield were taken as experimental variables and analyzed using SAS software. The result showed that grain yield, thousand kernel weight and hectoliter weight were significantly affected by interaction of Nitrogen and varieties. However, days to heading, days to maturity, plant height, number of productive tillers, straw yield and number of grain per spike were significantly affected by both N and varieties. On the other hand days to emergence, spike length and harvest index was not significantly affected by N and varieties. The higher (2.705 t ha-1) grain yield was recorded from the combination of Ibon variety with 57.5 kg N ha-1. Therefore, application of 57.5 kg N ha-1 fertilizer rates and Holker variety and 57.5 kg N ha-1 and Ibon variety were found to be better in terms of agronomic for malt barley production at central highland of Arsi, Ethiopia.
Maxillary anterior teeth are the most affected teeth from dental trauma. The immediate reattachment of natural tooth fragment is a good alternative option as an emergency treatment for remaining aesthetical and functional problem. This treatment offers a conservative, aesthetic, and cost effective restorative option that has been shown to be an acceptable alternative to the restoration of the fractured area with composite resin or crown. In this case report we presents a clinical technique of reattachment of coronal fragment of maxillary central & lateral incisor after trauma using glass fibre – reinforced composite post systems.
Integrated Application of Organic and Inorganic Fertilizer to Improve Nutritive Quality of Maize and Soybean Intercrop
A field experiment was conducted to evaluate the use of integrated fertilizers on the nutritive quality of maize and soybean in intercropping system in 2014 at field 2, Universiti Putra Malaysia (UPM) Serdang, Selangor, Malaysia. Fertilizer applications were either in the form of inorganic (NPK) or poultry manure (PM). Treatments comprised of combinations of three intercropping systems (sole maize, sole soybean, and maize + soybean) and four nutrient managements (control, 100% NPK, 100% PM and 50 % NPK + 50% PM). The experiment was laid out in a randomized complete block design (RCBD) with 3 replications. Results showed that intercropping maize with soybean significantly reduced protein and nutrient content of soybean; however, the oil content of soybean, sugar, oil, protein and nutrient content of maize were not significantly affected by intercropping. Sole and integrated application of NPK and PM increased the quality of both crops over control. Integrated application of 50% NPK and 50% PM fertilizer gave higher oil, protein and nutrient content of both crops. Use of 100 % PM gave better quality than the application of NPK fertilizer for both crops.
Histological and ultrastructural studies of myocardium lesions produced by hair dye (para-phenylenediamine) in rats
Para-phenylenediamine (PPD) is an aromatic compound and usually applied in a few commercial and mechanical products. Additionally, ladies apply henna for coloring their hair, which contains PPD as one of the components. Henna is used in East Africa, India, and Middle Eastern countries as a part of their culture. However, it is rarely found in western countries. The aim of this study was to examine the effect of two different doses of PPD topical application on the skin of female rats. The microscopic analysis indicates that the body and heart weights were affected. Histopathological studies on cardiac fibers showed that the treatment of rats with 1.5 ml of PPD resulted in increased cytoplasmic vacuolization and the loss of myocardial cells with a globular nucleus. Additionally, an increased dose of 3 ml PPD showed several signs of cardiotoxic effects on increased cytoplasmic vacuolization and myofibrillar loss. Congestion, focal necrosis, swollen mitochondria, and lymphoid infiltration were also observed. Considering the findings of this study, it is concluded that the chronic usage of PPD promotes histopathological alterations in heart tissue of rats.
