Use of Fermented Wheat (Triticum spp) Waste Meal in the Diet of Clarias gariepinus fingerlings
Get PDFFingerlings of Clarias gariepinus were stocked into ten tanks at ten fingerlings per tank and subjected to five treatments replicated twice. Fermented wheat waste meal, which was the test ingredient, was included at 0%, 20% 40%, 60% and 80% in five diets formulated at 40% crude protein. The experiment lasted for 70 days. Fish fed with diet D5 had the best growth rate with specific growth rate of 2.20±0.08, feed conversion ratio of 0.08±0.05 and protein efficiency ratio of 0.63±0.04 while fish fed with diet CTR had the least growth rate with specific growth rate of 1.73±0.21, feed conversion ratio of 1.26±0.29 and protein efficiency ratio of 0.41±0.09. The cost of the experimental diets showed that the cost of production of 1kg feed reduced as the level of inclusion of the test diet increased. Hence, fermented wheat waste can replace maize as an energy source in the diet of Clarias gariepinus fingerlings up to 80% inclusion level without adverse effect on growth and nutrient utilization and this will also reduce the cost of production

A Review of the Implementation of Private Finance Initiatives in UK Hospitals
Get PDFSince their inception in 1992, Private Finance Initiatives (PFIs) have become the dominant mode of procurement for UK National Health Service (NHS) hospitals. The private sector initially finances new initiatives which are then repaid through unitary service charges. Despite a great deal of rhetoric around the promise and potential of this funding mechanism, more recently PFIs have been criticized for bringing some NHS trusts to the brink of bankruptcy. Moving forward, assessing whether PFIs can achieve their intended purpose; the provision of more sustainable and affordable solutions, is critical in determining their future usefulness. The purpose of this paper is to identify past and current benefits of the PFI, and evaluate post implementation problems. Our results suggest reduced labour costs and greater productivity are paramount, as is sharing risk. However, in measuring whether PFIs have delivered these benefits there has been a dearth of quantitative performance measurement. Additionally little research has concentrated on critical analysis and performance of PFIs, hampering attempts to evaluate the affordability and sustainability of this solution
Studies on Fish Diversity and Condition Factor of Fish Species of Ogbei Stream, Southern Nigeria
Get PDFThe present study which is aimed at studying the condition factor of fish speciesof Ogbei Stream was carried out for a period of six months (January – June 2005). Eight (8)species belonging to seven (7) families and four (4) orders were identified from a total of 44individuals. The family Cichlidae was more abundant and more diversified having three (3)species namely Tilapia zilli, Oreochromis niloticus and Parachana obscura. Other familieshad one (1) species of fish each. Tilapia zilli had the highest percentage composition(34.01%) followed by Clarias anguillaris (25.00%). Parachana obscura, Labeo senegalensisand Erpetoichythes calabaricus had equal percentage composition of 02.27%. Five (5,62.5%) of the fish species had condition factor greater than 1.0 while three (3, 37.5%) hadcondition factor value that approximately ranged from 0.1 to 1.0. Thus the fishes especiallyMalapterurus electricus are doing well. It is envisaged that this study will serve as a baselinefor future work and rational management of fishery resources of Ogbei Stream
Physics Process Skills and Its Acquisition on Secondary School Physics Students in Aguata and Nnewi Education Zones of Anambra State
Get PDFThis research work aimed at studying Physics process in skills and its acquisition by senior secondary students who wish to pursue Physics at Senior Secondary, the subject enables the students to participate in technology related studies in tertiary institutions. Many students opt out of Physics at the end of Senior Secondary level. Physics process skills are central to the acquisition of scientific knowledge which is useful in solving problems in society. Physics science as an integral part of science is known to be very important in a nation’s development. The process skills of physics are invaluable tools for learning physics, and the acquisition of these skills has therefore been greatly emphasized in recent times. However, the often reported poor performance of secondary school students in physics, especially in this research to ask whether secondary school physics students actually acquire and use physics process skills in their study of physics, and to what extent. This study, conducted in Anambra State of Nigeria, was intended to provide empirical evidence to answer these questions. It was further intended to determine how such factors as gender and school location affect students' acquisition of physics process skills. Fourteen (14) physics process skills identified from the National Curriculum for Science (Physics) as the most frequently' occurring skills, were studied. The design of the study was survey in which the researcher studied events as they are in their natural setting. Six research questions were posed and addressed while three hypotheses were formulated and tested at the 0.05 level of significance. A total sample of 756 SS three (3) physics students (514 Boys and 242 Girls) randomly drawn from both, urban and rural secondary schools in two education zones Aguata and Nnewi of Anambra State participated in the study. A Test of Physics Process Skill (TOPPS) designed by the researcher was the instrument used for gathering data. The data collected were analyzed using means and standard deviations for answering the research questions, while the analysis of variance (ANOVA) was used for testing the hypotheses. The major findings of this study are that: (i) the level of acquisition of physics process skills among Anambra State Secondary school physics students was generally low; (ii) gender is a significant factor (p<.05) in the students' level of acquisition of physics process skills, in favour of the male students; (iii) students located in urban schools were significantly superior (p<0.5) to their rural located counterparts in their acquisition of physics process skills; (iv) there was no significant interaction effect (<.05) between gender and school location in students' level of acquisition of physics process skills. A number of educational implications were pointed out and relevant recommendations made. Limitations of the study were noted and suggestions for further research made

Tax Diplomacy
Get PDFThe aim of this paper is to analyse the methods of achieving coordinate tax systems, and practical application of the best tax practices of one country to another, with emphasis on the significance of a country's membership in particular associations, namely the OECD, fiscal decentralisation and the increasing coordination of tax systems on the global level with the subsequent effect of interconnection. The presented hypotheses are: Membership in the Organisation strengthens tax integration and emphasizes the effect of diplomacy in coordinating tax systems; Strengthening of tax diplomacy and fiscal cooperation ensures creation of new methods of preventing tax evasion. In order to test the hypotheses, descriptive and comparative research methodology of the OECD members and non-members were used. Both hypotheses have been confirmed, leading to the conclusion that membership in the OECD results in better tax integration and transparency, reduced tax evasion and enhanced understanding and willingness of taxpayers to participate in the tax system
urban Scalable Geospatial Proposal for Calculating a Social Capital Score for the Labor Market: İşgücü Piyasası İçin Bir Sosyal Sermaye Puanı Hesaplama Önerisi
No full textİşgücü piyasası açısından sosyal sermaye, işgücü ile işveren arasındaki güvene dayalı ilişkilerden doğan bir değerdir. Sosyal sermaye birikimine sahip olan üniversite mezunlarının, iş arama sürelerinin kısalması ve niteliklerine uygun işlerle eşleşmesi ve daha görünür hale gelmesi beklenmektedir. Bu bağlamda, mezunların sosyal sermaye birikimini öğrencilikleri süresince edinmeleri gerekliliği ön plana çıkmakta ve böylece üniversitelere, bu birikimi kazandıracak kanalların oluşturulması sorumluluğu yüklenmektedir. İşgücü piyasasının talep tarafında, işverenler istihdam kararı alırken; adayın akademik ortalamasından öte, bireyin sosyal sermaye birikimi ve bu yolla alanda edindiği deneyim ve tecrübeleri ve hatta sosyal yaşamındaki sosyal sermaye ve etkinlikleri fazlasıyla önemsemektedir. Ancak adayın alana özgü sosyal sermayesini gösteren somut bir göstergenin olmaması, işverenin seçim yapmasını güçleştirmekte, çoğu zaman akraba, yakın çevre gibi sınırlayıcı nitelikte sosyal sermaye kanallarını işletmesine ve böylece işgücü piyasasının etkinliğinin bozulmasına neden olmaktadır. Böyle bir göstergenin elde edilmesi işverenin daha etkin karar verebilmesini sağlayacaktır.Çalışmadamezunların alanlarına dair sosyal sermaye birikimini belirlemeye yönelik bir puanın hesaplanması hedeflenmektedir. Bununiçin Analitik Hiyerarşi Prosesi (AHP) yöntemi kullanılmıştır. AHP, farklı önceliklere sahip birden fazla kriterin sistematik olarak karşılaştırılıp değerlendirilmesini sağlamaktadır. Genellikle AHP seçenekler içinden en iyisinin belirlenmesinde kullanılan bir teknik olmasına rağmen bu çalışmada yaygın kullanımından farklı olarak mezunların sosyal sermaye birikimlerini değerlendirmekte kullanılabilecek birden çok kriterin önem derecelerini göz önünde bulundurarak birleştirilmesi ve tek bir puana dönüştürülmesinde kullanılmıştır
