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. The study concluded that to enhance technological innovation in Nigerian rice processing industry, there is a need for the development of strong linkage between the industry and the stakeholders involved in rice processing operations.
Contribution/ Originality
This study has contributed to the existing literature through the establishment of the state of technological innovations identifiable in rice processing industry. It also provides the existing relationship between rice processors and stakeholders involved in rice processing operations.

Abstract
This study was conducted in Simien Mountains National Park, Northwest Ethiopia with the objective of evaluating the patterns of plant community formation and vegetation structure in the afro- alpine vegetation. The data were collected from stratified mountains by using systematic sampling in each stratum from October to November 2015. A total 62 (20 m x20 m) main plots were sampled. In each main plot five (1m x1m) subplots, one at each corner and one at the center, were used to collect data for herbaceous species. In each plot, data on plant species identity, abundance, height and Diameter at Breast Height (DBH) were recorded. Collected specimens were identified at field and also at National Herbarium, Addis Ababa University. Plant community analysis was performed using R version 3.1.3. Sorensen’s similarity coefficient was used to detect dissimilarities among communities. Shannon - Wiener diversity index was computed to describe species diversity of the plant community types. Results showed that a total of 86 plant species representing 34 families and 63 genera were recorded from which90.7 % were herbs, 7% shrubs and 2.3 % trees. Asteraceae is the species richest family whereas Poaceae is the dominant. Three plant community types were recognized from cluster analysis. Species richness, diversity and evenness varied among the plant communities. Analysis of population structure of the dominant species revealed various patterns. Because this afro-alpine area has varied habitat heteroginity, separate plant community regimes need separate planning and implementing (management) measures for sustainability of the vegetation.
Contribution/ Originality
This study contributes in the existing literature by providing basic information for other researchers regarding the patterns of plant community formation and vegetation structure in the afro-alpine vegetation of Simien Mountains National Park, Ethiopia. Moreover this study documents the patterns of plant community formation and population structures of the Simien Mountains National Park within the study period.

Export to    BibTeX   |   EndNote   |   RIS

Abstract
Athletic identity is a key factor in multiple areas in a student-athlete’s career however, athletic identity is both fragile and critical simultaneously, effecting things such as self-confidence, self-identity, and reputation around campus. Through interviews with 10 football players at a Mid-Atlantic American Division 1 University, qualitative data was gathered examining interests outside of the sport, their process of becoming a Division 1 athlete, and preparation for life after football. Primary findings explored common trends among the participants such as shared long-term goals, sport attached identity, and the absences of post athletic-career skills, or even exposure to such skill training at their university. Additional results suggested participant student-athletes have a solid sense of who they are but do not have a stable outlet for who they want to become outside of sport. This study can inform universities that student athletes not only desire innovative methods for career development, but also possess diverse ideas for their future beyond the student-athlete experience.
Contribution/ Originality
This study is one of the very few studies which examine the current state of post-athletic career resources available to American Division 1 collegiate athletes. From an athlete-identity framework, this quasi-experiemental study sheds light on the current state of elite Division1 football through the lense of a student-athlete.

Journal: International Journal of Climate Research

Export to    BibTeX   |   EndNote   |   RIS

Abstract
This study examined the variation of atmospheric stability conditions in Nigeria’s climate belts using the Pasquill-Gifford (PG) technique. Surface meteorological data (2010-2015) from Era-Interim platform were used. Results show that across climate belts in Nigeria unstable conditions increased from the coast of Port Harcourt (tropical wet climate) to Kano (tropical continental climate) in the northern part of Nigeria. There is a revered trend for the neutral conditions. It is also observed that stable atmospheric stability conditions are slightly higher in the tropical continental climate and the semi-arid zone than the coastal zone. However the climate of Nigeria is dominated by the unstable atmospheric conditions. Very stable atmospheric conditions (stability class F) prevailed during the hours of the dawn for most of the seasons in the coastal areas while less stable atmospheric conditions (stability class E) prevailed in the semi-arid region of Nigeria. During the day, the boundary layer atmosphere is slightly unstable in the coastal areas and moderately unstable in the semi-arid belt. However, it indicates otherwise during transition periods. The implication of these atmospheric conditions across the various locations especially for the coastal city of Port Harcourt is that uncontrolled emissions will be constrained at ground level during the night due to subsidence inversion triggered by the very stable condition of the boundary layer. This will create health problems for boundary-layer dwellers exposed to severe air pollution episodes. Policy makers should ensure that emission reduction techniques are engaged by potential emitters sited near sensitive receptors in cities such as Port Harcourt.
Contribution/ Originality
This study contributes in the existing literature the pattern of stability conditions over the climate belts of Nigeria. This identifies the most prevalent stability category that could either enhance or suppress boundary layer emissions.

Abstract
Zinc (Zn) has antibacterial and antifungal properties, so, it is being widely used in food and pharmaceutical industries. Transition metal especially Zn deficiency has deleterious effects all over the world due to wide consumption of Zn deficient food byproduct. Several studies have reported that transition elements especially Zinc deficiency affects the endocrine and reproductive system. This overview comprises the information about negative effects of Zn deficiency on reproductive system of male rat and their possible outcomes. Scientific studies indicated that Zn deficiency severely affects the reproductive physiology of male rats. Zn deficiency suppresses the function of male rat testes inclosing spermatogenesis and steroidogenesis by reducing the production of androgen hormone. In addition, Zn deficient rats also indicated testicular atrophy, primary and secondary spermatogonial stem cells disruption, lower number of sperm cells count, sperm quality, motility, viability, enhance in oxidative stress, inhibition of Testosterone (T) level which, in turn may cause infertility. The different consequences in animal models by zinc application are dose and duration dependent. Several studies propose that both higher and lower Zn concentration can effects the rat reproductive function. Therefore, the available outcomes revealed that Zn deficiency might have significant influence on luteinizing hormone and follicle stimulating hormone affecting the sperm physiology and histology in certain tissues.
Contribution/ Originality
This recent study has contributed significant scientific information on a particular subject area “Zinc deficiency”. A lot of reports have discussed the Zinc and its effects on human but there is lack of sufficient data related to Zn deficiency on reproductive profile of male rats. Therefore, this study is one of very few studies which have documented that Zinc is necessary in male reproductive system of human and animals. On the other side, it is recommended that optimum amount of Zinc supplementation should be used to avoid the deleterious effects on male reproductive physiology.

Journal: International Journal of Public Policy and Administration Research

Export to    BibTeX   |   EndNote   |   RIS

Abstract
This research investigated the effectiveness of oversight committees in the City of Johannesburg, focussing on Section 79 committees which are constituted under Section 79 of the Municipal Structures Act, 1998, and which are tasked with performing oversight on departments. The problem with the separation of powers is that the performance and effectiveness of the oversight model in the City of Johannesburg Legislature (committees) has not been assessed and its performance level is still unknown. The objective of the study was to assess the effectiveness of the oversight model in holding the executive accountable. Interviews with thirteen respondents aided the researcher to gather valuable information, understanding, and insight, into the oversight model and its reporting function at the City of Johannesburg. The research findings show shortcomings in the oversight model, which include late reports, Executive absence from committee meetings, lack of tracking and implementation of committee resolutions, lack of political will and integrated reporting framework. The study recommends that the City of Johannesburg develop an integrated reporting framework in order to assess the efficacy of the oversight model by engaging the services of retired professionals. Also, the City should develop a booklet with all relevant legislation and policies for oversight purposes.
Contribution/ Originality
This study documents and highlights the shortcomings in the present oversight model which, since inception, have not been assessed. The programmes and objectives of the oversight committees have therefore not been effectively monitored and evaluated. These factors have hampered the effectiveness of the section 79 committees within the City of Johannesburg.

Abstract
The longevity of cut flowers including cut roses can be however prolonged using different pulsing preservatives where researches in this regard are lacking in the country. Keeping these bottlenecks of the sector in mind, this study was therefore initiated with objective to evaluate the effectiveness of different pulsing preservatives in prolonging vase life of cut rose varieties. The experiment was conducted at Tana Flora PLC in Bahir Dar, Ethiopia. As pulsing preservatives Al2(SO4)3)(250 mg-1), Ca(ClO)2 (66.7 mg-1), STS [Ag (S2O3)2] (0.5 ml-1), Sugar (20 g-1) and distilled water were used. The three rose varieties namely: Upper class, Athena and Moon walk were used. Healthy flower buds having uniform length and harvested early in the morning were put immediately in containers filled with the respective concentration of pulsing preservatives. Flasks with six rose flowers each were placed in pre-cooling room (8-10 OC) for about 2 hours. Finally, treated cuttings were transferred into experimental room with temperature of 22-250C and 75% relative humidity and arranged in Complete Randomized Design (CRD) with three replications. At this time, pulsing preservatives were replaced by distilled water. The analysis of variance revealed that most of parameters were highly significantly influenced by the main as well as interaction effects of pulsing preservative and varieties (P<0.0). Maximum water uptake (7.73 g/flower/day), transpiration loss (7.08 g/flower/day), flower fresh weight (21.77 g/flowers), flower head diameter (7.6 cm), and maximum flower vase life (23 days) were recorded in Athena variety pulsed with STS.
Contribution/ Originality
This study is one of very few studies which have investigated to improve the shelf life and quality of rose flowers particularly in our country. Therefore, the present finding will contribute to flower growers through identifying appropriate pulsing preservatives for rose cut flower.

The outcomes and the relevant conclusions, resulting from the processing and analysis of primary data, are presented along with a proposal for further research. According to these conclusions, the teachers’ stress is increased in the 3rd and last grade of senior secondary education, because of the national admission examinations to tertiary education that their pupils participate in. The stress-levels are exacerbated by parents and their expectations of their children’s success. For reducing professional stress, different strategies are applied by individual teachers, headmasters and Teachers’ Associations.
Contribution/ Originality
This study contributes in the existing literature about teachers’ professional stress, by presenting the strategies for reducing the stress of teachers in senior secondary education of Greece, applied by headmasters and Teachers’ Associations, along with a few general policy proposals for dealing with this issue.

Abstract
This paper estimates the impact of macroeconomic indicators on the growth of capital formation in Nigeria. Adopting the Autoregressive Distributed Lag Model (ARDL), the empirical findings showed that Foreign aid which is proxied by Overseas Development Assistance (ODA) and Domestic Private Investment (DPI) had positive impact on capital formation growth in Nigeria, while exchange rate, trade openness, and external debt had negative impact for the period under review. The study therefore recommends that aid, especially from the West should not be highly depended upon as a major source of revenue for the development of the economy. Other macroeconomic determinants of capital growth that government should encourage include; savings, investment and the quality of institutions.
Contribution/ Originality
This study tests the impact of macroeconomic indicators on the growth of capital formation in Nigeria within the framework of the Autoregressive Distributed Lag Model (ARDL).

Abstract
Using a novel approach, this study disaggregates and estimates the impact of foreign capital inflows on unemployment in Nigeria by adopting the Auto-Regressive Distributed Lag- Unrestricted Error Correction Methodology (ARDL-UECM). The ARDL-bounds test co-integration results show evidence of co-integration between disaggregated Foreign Capital Inflow variables (such as Foreign Direct Investment, Foreign Portfolio Investment and Remittances) and unemployment rate in Nigeria within the period from 1977Q1 – 2013Q4. The empirical results also show that foreign direct investment, foreign private investment and trade openness have negative impact on unemployment rate. On the other hand and interestingly, remittances and real exchange rate show a positive impact. The study therefore recommends the routing of remittances through the banking channels which would help in allocating remittances and other financial flows to productive uses. Again, government should enact investor-friendly policies and build conducive business environment in order to attract more Foreign Capital Inflows which will support job creation for the teeming population and thereby reduce biting unemployment.
