Abstract
Bubugn is a cereal based traditional fermented Ethiopian low alcoholic beverage. It is one of the traditional fermented beverages used for a drink of holidays, wedding ceremony and also used as a source of income. The aims of this study were to determine the microbiology, microbial contaminants and physicochemical characteristics of Bubugn. Nine Samples of Bubugn were collected from Gondar town in three district areas; Azezo (A), Arada (B) and Kebele 18 (C). Microbial counts and physicochemical analysis were enumerated using standard microbiological methods. The mean value of the pH of the samples was 4.20 + 0.14; and the mean value of moisture content was 45. 79 +1.35. The mean crude fat, ash and ethanol contents of Bubugn were 6.67 + 0.16, 4.47+ 0.40 and 1.79 + 0.13, respectively. The mean number of total mesophilic aerobic bacteria, yeasts and molds and lactic acid bacteria of Bubugn were 3.74×105 cfu/ml, 5.68 ×106 cfu/ml and 7.52×105 cfu/ml respectively. Bubugn samples were contaminated by Shigella species, E. coli and S. aureus which could be due to poor hygienic conditions related to washing of preparation material, use of contaminated water and poor personal and domestic hygiene. The collected Bubugn samples were contaminated by different microorganisms and therefore, there should be the development of an advanced technique to improve quality.
Contribution/ Originality
This study contributes to the existing literature by providing necessary information for other researchers regarding the microbiology, microbial contaminants and physicochemical properties of Bubugn, a traditional fermented Ethiopian beverage.

Abstract
This study used scenario analysis to estimate the economic impact of the expenditures of anglers who participated in offshore fishing tournaments in Ocean City, Maryland. The primary purposes of this study were to evaluate impacts on the adjacent areas, to identify potential uses for economic impact information, and to provide justification for investment and support of programs related to the needs of coastal communities and issues related to marine recreational fisheries management. To accomplish this study, the IMPLAN modeling system was employed to calculate the economic impact of offshore fishing tournaments on local and regional economies. Preliminary results using scenario analysis suggested the total economic impact of offshore fishing tournaments in Ocean City could be nearly $2.2 million for Wicomico and Worchester counties. To get this estimate, three different scenarios were considered based on potential expenditure estimate of what each tournament party would spend on lodging, fuel, food, fishing and miscellaneous costs. Using IMPLAN, impact metric categories could be generated including general labor income, job opportunities - employment, and value added. This paper provides the extent to which fishery managers, municipalities, business and private sector stakeholders could benefit from local marine recreational fishing tournaments, and potentially justify investment in infrastructure which supports marine recreational fishing.

Abstract
This study examined the relationship between employee loyalty and organizational citizenship behaviour in the Port Harcourt Area Command of the Nigeria Police Force. The study adopted a cross-sectional survey research design. The primary source of data was a structured self-administered questionnaire. The population of this study consists of Senior Police officers from the rank of Assistant Superintendent of Police (ASP) and above, and the other ranks made up of Inspectors and Non-Commissioned Officers (NCOs) working in the twenty-seven (27) Police Divisions distributed in four (4) Local Government Areas of Rivers State, Nigeria which has a total staff strength of 14,886. Due to the large size of the population, the Taro Yamane Sample Size determination techniques were used to determine the sample size of 390 employees, which were selected through stratified random sampling. Internal reliability of the instrument was achieved through the Cronbach Alpha coefficient with items being above 0.70. After data cleaning, only data of 332 respondents were finally used for data analysis. The Pearson's Product Moment Correlation tool was used for hypothesis testing. The study findings revealed that there is a positive significant relationship between employee loyalty and organizational citizenship behaviour. The study thus concluded that employee loyalty bears a positive and significant influence on organizational citizenship. Managers should endeavour to develop a supportive connection with employees in a manner that would enhance employees desire to act or perform beyond their required role.
Contribution/ Originality
This study is one of the few studies to have investigated employee loyalty and organizational citizenship behaviour in the Port Harcourt Area Command of The Nigeria Police Force.

Journal: Journal of Tourism Management Research

Export to    BibTeX   |   EndNote   |   RIS

Abstract
This paper aims to examine the effectiveness of poster presentation in assessing the tourism students’ competencies. Three issues were investigated including the students’ responses, strengths and weaknesses and the students’ recommendation for more practical students’ learning. This research employed a case study approach (from July to December 2017) at Makassar Tourism Polytechnic, Indonesia. The study reveals that although students were worried about the implementation of poster presentation, the students were successfully participated in the examination through poster presentation. Three strengths were found including the students understand topics and sub-topics of a subject; link tourism concepts with the real context; and improve their self-confidence. This paper recommends the implementation of poster presentation for two reasons; 1) it supports the students to learn tourism concepts and issues independently; 2) it implements systematic ways including input (lecturer explains it), process (students prepare their poster), and output (students’ competencies).
Contribution/ Originality
The paper's primary contribution is finding that poster presentation has provided the opportunity for students to have intercultural competencies and sense of responsibility on environmental issues. Poster presentation is an option for teachers to assess the students’ competencies. It enables students to create and present poster through critical thinking.

Did Global Warming and Climate Change Cause the Degradation of Lake Chad, Africa's Most Important 'Ecological Catastrophe'?

Research Article
Author(s): Enwere Dike, Ngozi Dike
Journal: Review of Environment and Earth Sciences

Export to    BibTeX   |   EndNote   |   RIS

Abstract
This paper explores six hypotheses/theories on Lake Chad’s degradation: i) natural climate variation; ii) anthropogenic climate change compounded the effects of the Sahel drought; iii) unregulated exploitation of Lake Chad’s hydrologic system overdrew the regenerative potential of the lake system; iv) high rates of deforestation in the tropical rain forest belt of West-Central Africa shifted the rain belt Southwards; v) pressure from rapidly expanding human and livestock populations exceeded the carrying potential of the Lake Chad ecosystem; and vi) anthropogenic aerosol emissions in the northern hemisphere shifted the tropical rain-belt southwards. The evidence shows that there is no single-cause explanation for Lake Chad’s degradation; rather the influence of global warming and climate change compounded those from pre-existing drought conditions and non-climate factors e.g unregulated exploitation of Lake Chad’s hydrologic system to degrade the lake.
Contribution/ Originality
The paper contributes to the existing literature by exploring six hypotheses/theories to show that the influence of global warming and climate change on ecosystems can be compounded by non-climate variables. The degradation of Lake Chad illustrates vividly the interaction between the climate factors and non-factors in eco-system degradation.

Abstract
The study investigates the effect of economic, political and social institutions on FDI in Nigeria between 1980 and 2015. The Stock-Watson Dynamic Least Squares (DOLS) is relied upon for analyzing the data extracted from the World Bank WDI. The KPSS stationarity results indicate that all the variables were mixed integrated with FDI and political integration being levels stationary while economic and social factors were first difference stationary. The Johansen cointegration test finds evidence of two cointegrating equations in the model, indicating that long run relationship exists among the variables. The estimated cointegrating regression model showed that economic and social integrations were highly significant in explaining changes in FDI. Political institution factors, on the other hand, have an insignificant positive relationship with FDI. The Wald test showed evidence to support that the coefficients of the regressors were significantly different from zero. The result of the Granger causality test reveals that political and social institution has high predictive power for FDI flows to the Nigerian economy. Based on the findings, this study recommends that Nigeria should adopt a gradual reduction in all economic, political and social constraint to FDI inflows to optimize the benefits of foreign direct investment in Nigeria.
Contribution/ Originality
This paper is one of very few studies which have investigated the role of institutional quality in mobilizing FDI in capital deficient economies. Its measure of institutional quality from social, economic and political dimensions is noteworthy which add significantly to the existing literature.

Abstract
Anger, although it is a natural emotion, when it cannot be managed, individuals experience extremely serious problems; at an extreme, they might even engage in criminal behaviors. The behaviours of people have some physical, hormonal, environmental, psychological and social causes that have positive or negative effects on anger. In this respect, it is crucial to understand the reasons for anger in preschools, which are an essential period in the formation of personality. The perfect behaviors of mothers, fathers, caretakers and other members of the family as well as the model behaviors of teachers and school administrators all can have an impact on the child. People dealing with an obstinate child or one throwing a temper tantrum may also become angry. In such cases, adults have an obligation to manage their anger as well as to help the child control his/her anger. The training received and the model samples encountered in the preschool period are significant determinants of the anger behaviors displayed in adulthood. When the fact is considered that there are teenagers or young adults who face serious problems due to instant loss of their tempers and even commit murders, the necessity of anger management training and proper model behaviors in the preschool period becomes more essential.
Contribution/ Originality
Violent behavior in society is the result of uncontrollable anger. Although there are many reasons for uncontrollable anger behaviors, it is also something can be learned. In the pre-school period, where the learning potential is highest. Therefore, this article, however, will contribute to studies on anger management in the pre-school period.

Journal: Humanities and Social Sciences Letters

Export to    BibTeX   |   EndNote   |   RIS

Abstract
Criminality is a familiar concept around the globe. The way by which it can draw the attention of people throughout the world is the severe frequency of it. State considers the committal of such criminality in its territory as internal security challenges. Bangladesh, due to its socio-economic and socio-political issues is harboring significant types of criminal offences. Organizational failure to keep its stakeholders in a controlled environment and the political failure to keep its citizen’s moral characters upheld may have fueled the mushrooming growth of criminal activities within the country. This paper is an analysis based on the secondary information found especially from the official police statistics of Bangladesh, Non-government organizations and other reliable sources. This paper argues that Century-old legacy of laws, lack of public confidence to the law-enforcement agencies and sense of immunity after the commission of crime inspired the potential offenders of the country years after years. Here, less moral or legal education still hinders children’s balanced growing up with proper civic sense. As a result, a great number of crimes in one case provoke fear among people and at a time, it generates an inherent subconscious mind of people for taking these incidents in a usual way. Impact of international terrorism and illicit drugs directed the overall crime situation of this country in an unexpected destination. For bringing a positive change there, a paradigm-shift is essential. The starting is not easy in the existing system but that is indispensable here. Strategic formulation and implementation of proper planning accompanied by exercising moral teachings can improve the situation. Most importantly, the state authority should pay their heed in improving the situation while formulating policies.
Contribution/ Originality
This study contributes in the existing literature with an analysis regarding the internal security challenges of Bangladesh and its seriousness. This study is one of the very few studies, which have investigated the overall crime situation of Bangladesh on the basis of police statistics.

Abstract
Social media is undoubtedly one of the factors used in measuring the effect of globalization in the world. As countries of the world strive for sustainable development on account of the fact that the world has become compressed as a global village, communication through the use of social media has been outstanding. The promotion of different cultural values of the world has also been possible in this direction. While some countries rely on the effectiveness of the social media to fit into the globalization grid for sustainable development in terms of culture cum economy, others especially the third world seem to see globalization as an obstruction to their development. This forms the interest of this study to determine the effectiveness of promoting the Nigerian cultural values in the globalization grid through the use of social media. This is a qualitative study that describes the dependence on social media for communication purpose among the population in Calabar, Cross River State of Nigeria, and the extent to which the diffuse information globally. The submission, therefore, is that globalization is a paradigm for sustainable development of countries of the world; and based on the pervasiveness of the social media, Nigeria can positively promote her cultural values globally.
Contribution/ Originality
This paper is one of the few studies which have investigated the positives of cultural cum socio-economic relevance of globalization in developing economies like Nigeria; and has demonstrated how effective the social media can be as a factor in globalization paradigm to promote cultural values.

Abstract
Automated Storage and Retrieval Systems (AS/RS) are being widely used in the logistics industry. This typical System, Systems are computer controlled storage systems that can automatically store and retrieve loads. Major advantages of AS/RS include high throughput, efficient use of space, high reliability and improvement of safety. There are some different operational modes in typical system. The choice of operational mode depends on the storage location assignment policy. Shared storage approach is one of these policies. In this approach, the empty space created by an act of accumulation throughout recovery can be quickly filled which conduces to save time and money. This paper examines the joint optimization of (AS/RSs) scheduling in multi-shuttle AS/RSs under shared storage in fuzzy and dynamic environment. From the view of analytical model, the advantage of operational mode under shared storage is verified. For optimization multi-shuttle automated storage and retrieval system to minimize travel time, present a zero-one fuzzy mathematical programming model. Use Genetic algorithm (GA) with Matlab software to solve large-sized problems. Various numerical experiments are conducted to evaluate the performance of the proposed algorithm and investigate the impact of different parameters on computational efficiency. The result indicates that in matters where the primary objective is to reduce travel time cycle, shared storage policy is appropriate. Furthermore, the fuzzy sets theory can be an effective tool to model the uncertainties which are available around the real applications.

Research Article
Author(s): Deliverska E, Kirilova J, Stefanov L
Journal: Journal of Diseases

Export to    BibTeX   |   EndNote   |   RIS

Abstract
Bullous pemphigoid /BP/ is a chronic blistering disorder that can affect oral mucosa very rarely. This autoimmune disease typically has a gradual onset and a chronic progressive course with exacerbations and remissions. Against components located in the epithelial basement membrane are formed autoantibodies. It is important to perform an incisional biopsy to establish a definitive diagnosis. Direct immunofluorescent findings are identical in BMMP and BP. Indirect immunofluorescence shows circulating IgG antibodies against the components of basement membrane in the majority of cases with BP but very rarely in patients with BMMP. There is no correlation between antibody titer and disease severity in BP. The aim is to present a very rare case of bullous pemphygoid of oral mucosa histologically proved with immunostaining. We present a patient with clinically identified oral lesion - bullae with clear fluid content in buccal mucosa of maxilla. After the rupture of bullae it left painful, superficial, ulcerated areas of oral mucosa. Hystopathological examination revealed subepithelial blister formation with clean separation of the full thickness of the epithelium from the underlying connective tissue layer. Direct immunofluorescence revealed a continuous linear band of immunoreactants at the basement membrane area. This immune deposit consist mainly IgG and C3, localized in the basement membrane. Conclusion: The treatment depends on the severity of the disease, tendency of progression and the affected areas. Therefore the clinicians should thoroughly examine all mucosal sites in order to make a proper diagnosis. The chronically characteristic of this autoimmune disease can lead to significant morbidity to patients. The adverse effects from long-term use of corticosteroids and immunosuppressives agents can also contribute to morbidity.

Abstract
There is a few claimed in literature and financial media that gold, Islamic stock and commodity market provide as hedging tool against inflation. Therefore, derive from this similarity characteristic, we are interested to know which among of this investment variety are the leader and laggard in the Malaysian market. Among of them, numerous studies have been done on gold as a hedge against inflation, but almost non-existence amount of research endeavor to analyze the lead-lag of this precious metal with other investment avenues. Thus, several methods are employed to answer the issue of this study which are unit root tests and Johansen’s cointegration test, followed by long-run structural modelling (LRSM) and vector error-correction modelling (VECM), variance decompositions (VDCs), impulse response functions (IRFs) and persistence profile (PP). The results showed that spot Kijang Gold lags all investment avenues in Malaysia. It indicated that the performance of the Kijang Gold is dependent on FTSE Bursa Malaysia Emas Shariah Index, macroeconomic variables and strategic commodities. This provides some important policy implications in the regulation of the Kijang Gold itself whereby FTSE Bursa Malaysia Emas Shariah Index performance and other variables are among the key predictive inputs on the expected performance of the Kijang Gold. Hence, we humbly suggest to the investors and investment portfolio managers to include Islamic shariah equities, crude palm oil and crude oil commodities as part of their investment portfolios as may act as diversification and hedging tool especially for an investment portfolio which consists of Kijang Gold and forex, as we had identified these latter investment avenues as the most follower (endogenous) variables.
Contribution/ Originality
This study is one of very few studies which have investigated the lead-lag analysis among these three-investment avenues by using VECM, VDCs and other related techniques. Furthermore, this study attempts to fill the gap in empirical studies and associated theory which remains unexplored and not broadly discussed in the literature.

Abstract
High performance TiO2 photoanodes undoped and doped with silver nanoparticels of size about 15 nm were fabricated. Employing these electrodes dye-sensitized solar cells (DSSCs) were fabricated using N719 dye as sensitizer and iodide-triodide as redox couple. Current-voltage measurements were performed under the illumination of 100 mW cm-2 (AM 1.5). The electrical parameters of the fabricated cells were extracted from the current-voltage data that include open-circuit voltage, short-circuit current, shunt resistance, series resistance, fill-factor, ideality factor and solar energy-to-electricity conversion efficiency. The comparison of parameters revealed improvement in both the photovoltaic and electrical parameters of the plasmonic cell. The conversion efficiency measured for the reference cell without Ag NPs in TiO2 was 7.43 %, whereas the efficiency of plasmonic device with TiO2:Ag NPs was 9.26 %, resulting an overall efficiency improvement of 23% with Ag NPs. The increased performance of the plasmonic DSSC can be assigned to the improvement of its photovoltaic and electrical parameters. The improved short-circuit photocurrent density appears to be boosted due the enhanced light harvesting capability of the photoanode caused by the localized surface plasmon resonance effect induced in Ag nanoparticles. While, the rise in Voc can be credited to the upward shift of Fermi level of TiO2 due to the dopping of Ag nanoparticles in TiO2 network.
Contribution/ Originality
This study is based on one of the few attempts on photoanode engineering employing plasmonic effect for developing higher efficiency DSSCs. The comparison with the existing data has revealed significant improvement in the photovoltaic and electrical properties of the plasmonic device. This study has reported that Ag nanoparticles hold a unique plasmonic effect employing which performance parameters of the DSSC are improved much greater as compared to other metallic nanoparticles.

Abstract
The study examined the state of technological innovations in rice processing industry and investigated the level of interaction that exists between rice processors and stakeholders involved in rice processing operations in Nigeria. Data were collected from 35 (12 integrated and 23 medium and small-scale mills) rice processing firms in four geopolitical zones of Nigeria through the use of questionnaire. These firms were selected using snow balling sampling technique. The questionnaire elicited information on the state of technological innovations in the firms and the level of existing interactions among rice processors and relevant stakeholders. Data were analyzed using descriptive statistics. The result showed that majority (71.4%) of the firms had technological innovations involving introduction and improvement of existing product and 45.7% of them had technological innovations involving introduction of a new process and improvement of the existing process. More than two thirds (82.9%) of the firms carried out technological innovations mainly by themselves. Also, 65.7% of the technological innovations originated mainly in Nigeria, 31.4% were imported while 2.9% were sourced jointly in Nigeria and abroad. The results further showed that the firms have low (mean < 2.58) level of interactions with important stakeholders such as banks, local suppliers of equipment, universities/research institutes, foreign firms and government with a mean of 2.91, 2.57, 2.49, 2.09 and 1.86 respectively.

Abstract
PVT (pressure-volume-temperature) properties of reservoir fluids in the oil and gas industry constitute an integral part of the required data for a thorough study of the reservoir, optimally compilation of oil production and operation schemes. In the absence of PVT data that measured in laboratory conditions, empirical correlation is used to evaluate these properties. These correlations cannot be applied universally due to the differences of crude oil composition, the working condition of geographical and oil environment. In the article widespread correlations and models was investigated in the field of prediction of PVT properties of reservoir oil from different regions. Their accuracy and productivity was thoroughly analyzed too.

Abstract
Scientific studies carried out on the use of thin layer edible films and coatings which can be consumed with food, are still maintained today. Edible films and coatings help to preserve the sensory qualities such as taste, aroma and appearance in various food products, prevent oxidative rancidity in meat and products, delaying ripening in fruits and vegetables, keep pigments in food products and extend shelf life in foods. Over the years, a variety of methods have been developed for the application of coatings to food as a result of scientific research conducted on the subject. In the production of these films and coatings, polysaccharides, proteins, lipids are being used as the main components. Resins are used to prevent water vapour permeability in all these used materials, solvents to effect tensile strength, and plasticizers to provide flexibility and permeability. Further studies were needed to be done on topics such as increasing the variety of foodstuffs that can be applied coatings food safety, the development of technological applications and the reduction of costs.
Contribution/ Originality
This study documents the recently research studies related with edible films and coatings that promising packaging alternative
