This study assessed the effects of different contents of two refined phosphogypsums (PG1, PG2) on standard consistency, setting times, compressive strength and sulfate resistance of cement. PG2 possesses higher water-soluble impurities such as P2O5, F content than PG1. The results were compared to those of cement containing natural gypsum (NG). The results showed that water demand of cement reduces when the content of the gypsums increases, especially with PG1 and NG. The phosphogypsums prolong the setting times of cement. The higher the gypsum content is, the more the 3-d compressive strength of cement can obtains. The low impurity phosphogypsum (PG1) accelerates the 3-d strength but lowers the 91-d strength of cement compared to the high impurity phosphogypsum (PG2). The strength of cement containing NG is always between those of the phosphogypsums at the ages of 3 and 91 days. There is a suitable content of gypsum to produce the highest strength of the cement at the ages of 28 and 91 days. Deterioration of the cement in sodium sulfate solution (50g/l) is more severely when increasing gypsum content. The sulfate resistance of cement containing PG1 is lower than that of cement containing PG2 or NG. Contribution/ Originality
This study is one of very few studies in Vietnam to investigatewhich have investigated the potential for using refined phosphogypsum to replace natural gypsum in cement for environmental protection in Vietnam. This study has reported that phosphogypsum content and impurities of P2O5 and F- significantly affect the properties of Portland cement.

Foreign Direct Investment in Zimbabwe: The Role of Uncertainty, Exports, Cost of Capital, Corruption and Market Size
Most of developing countries such as Zimbabwe see foreign direct investment as a panacea for augmenting domestic savings, generating employment, eradicating poverty and stimulating economic growth. Foreign direct investment also is associated with significant positive spillover benefits such as; facilitating technological progress, enhancing production efficiencies, promoting skills and knowledge diffusion and increasing international competitiveness. The paper investigated the role of cost of capital, uncertainty, exports, market size and other macro factors in attracting FDI in Zimbabwe. This paper relied on a time series analysis using Ordinary Least Regression equation for the period 1998-2017. Uncertainty and cost of capital were found to be negative and statistically significant whilst market size and lagged exports were found to be positive and statistically significant. The paper recommends adoption of policies that improve domestic absorptive capacity such as the elimination of uncertainties in the economy, promoting more trade openness, improving market size and liberalisation of credit and financial markets to reduce firm borrowing costs.

Journal: International Journal of Geography and Geology
This study aims to spatially assess the flood vulnerability then suggests appropriate vulnerability lessening and adaptation mechanisms in Rwanda. Six vulnerability factors namely the rainfall and temperature, total population, access to communication tools, poverty level and number of schools were analyzed. The Weighting Linear Combination (WLC) method in ArcGIS is used to analyze these factors and spread the resulting flood vulnerability countrywide. The results showed high flood vulnerability within the northern, western and southern provinces and Kigali city of Rwanda. This vulnerability is likely to rise due to the noticed low possession of communication tools and education delivery, which could help to enhance the risk awareness and preparedness among the vulnerable communities. The results of this study can help policy makers to understand the required community’s vulnerability lessening measures and ensure spread of mitigation and adaptation policies as per vulnerability extent within Rwanda. Contribution/ Originality
The paper primary contribution is finding that climate change risk, mainly the flooding are gradually causing severe losses and damages in Rwanda.

Organisational Predators of Workplace Deviant Behaviour in Hotel Industry
Counterproductive behaviour exhibited by hotels workers in Port Harcourt is alarming. Despite the consequences of deviant acts, operators of the hotel industry in Port Harcourt are less minded on the organizational antecedents of workplace deviant behaviour. This study proposed an integrated model that explains the relationship between organizational predators and workplace deviant behaviour (OP-WDB) in the hotel industry in Port Harcourt. The study used a structured questionnaire and sampled 138 hotel staff in Port Harcourt. Pearson Moment Correlation analysis was used. The result shows that four of the six organisational predictors have a positive and significant relationship with deviant behaviour in respect of hotels in Port Harcourt. The F- statistic was statistically significant indicating a valid model. It is recommended that hotel managers should promote the cordial relationship between managers and their subordinates for enhanced employee's civility behaviour. In addition, hotel owners and managers should formulate policies that can forestall a positive hotel work climate for employees. Once more, hotel managers should ensure that daily employee's activities are scientifically measured to avert cases of work overload. Finally, hotel managers should lead by example and ensure that employees' trust in management is total.
Contribution/ Originality
This study contributes to the literature on workplace deviance in the hotel industry. The research proposed and validated an integrated model that explains the relationship between organisational predators and workplace deviant behaviour (OP-WDB) in an emerging country.

Study of Graphene-MoS2 Based SPR Biosensor with Graphene Based SPR Biosensor: Comparative Approach
Research Article
Author(s):
Journal: International Journal of Natural Sciences Research
In this paper, we compare the sensitivity of graphene-MoS2 based surface plasmon resonance (SPR) biosensor to graphene based SPR biosensor. Here, graphene is used as biomolecular recognition element (BRE) because of its high adsorption ability and optical characteristics which helps to improve sensor sensitivity, on the other hand MoS2 is used for it has larger band gap, high fluroscence quenching ability, higher optical absorption efficiency which improves further sensor sensitivity. In DNA hybridization event, numerically achieved results show that single layer of graphene-MoS2 based SPR biosensor is 175% more sensitive than single layer of graphene coated SPR biosensor. Surface plasmon resonance angle and spectrum of reflected power are numerically investigated for different concentrated complementary DNA strands. The variations of SPR angle is significantly computable for complementary DNA strands whereas these parameters are varied negligibly for mismatched DNA strands. Thus the proposed sensor effectively differentiates hybridization and single nucleotide polymorphisms (SNP) by examining the level of changes in SPR angle and reflected power spectrum. Contribution/ Originality
This study is one of very few studies which have investigated numerically the performance parameters in terms of sensitivity with adding only graphene and other hand adding graphene with MoS2 layers based surface plasmon resonance biosensor.

Development and Quality Evaluation of Complementary Food Formulated from Sorghum, Soybean and Sesame Flour Blends
Complementary foods are foods that are not breast milk or infant formula introduced to an infant to provide nutrients due to inadequacy of breast milk. The quality of Complementary foods prepared from sorghum, soybean and sesame flour blends was determined in this research. The flours were prepared and blended at different ratios; 70:30:0, 70:20:10, 60:30:10, and 50:40:10. The chemical, sensory and physical properties of the individual flours and the most acceptable complementary food were determined. The results show that the complementary food (50% SORF, 40% SOYF AND 10% SESF) contained 24.1% protein while SORF, SOYF and SESF had 7.8%, 48.4% and 15.1% respectively. The complementary food has higher carbohydrate 48.1% than those of the SOYF (19.4%) and SESF (23.3%). However, the SOYF flour had higher carbohydrate (82.2%) than the other flours. The bulk density of the complementary food was 0.72g/cm3 while those of the flours ranged from 0.53 g/cm3 to 0.81g/cm3. All the flours lacked foaming capacity, values ranging from 0.98 to 6.9%. However, the complementary food had higher water absorption capacity and emulsion capacity than the individual flours. The sensory evaluation result showed that the blend containing 50% SORF, 40% SOYF and 10% SESF received higher scores for taste, flavor, texture, colour and overall acceptability than the other flour blends and the commercial weaning food. The result showed that acceptable complementary food with chemical and physical properties similar to commercial weaning food may well be prepared from sorghum, soybean and sesame flour blends. Contribution/ Originality
This study is one of very few studies that have investigated the production of complementary foods from local raw materials. The complementary food was produced from low-cost, nutrient dense cereal; legume and oil seed which will help solve the problem of malnutrition as the blend is rich in protein and other nutrients.

Residents Perception of Impacts toward Tourism Development: The Case of Bandung City, Indonesia
This article examines residents’ perceptions of the impacts of tourism development in Bandung City, Indonesia. The study aims to evaluate the 2009-2013 tourism policy and program’s outcomes. It uses primary data from the qualitative method of interviewing residents. Interviews were conducted in eight Bandung City districts during November 2014 and March 2016. The respondents were chosen based on the understanding that residents often do not represent a homogeneous population (Brunt and Courtney, 1999). Therefore, the respondents were divided into four types. The data analysis is modeled after Ritchie and Spencer (1994)’s framework method. The study found that the citizens’ common perception of a socio-economic impact are business opportunities. The perceived negative socio-cultural impacts was that the use of a local language, Sundanese, was declining due to tourism. The others included vandalism, and the increase of shopping places and culinary places affecting the citizens’ lifestyle via consumerism. Concerning local art and culture, type two, three and four respondents confessed that Bandung City tourism lacked cultural attractions. In contrast, type one of respondent admitted that tourism has the effect of reviving local art and culture and that they had experienced acculturation in traditional music. It shows that the local government efforts of promoting cultural tourism does not affect other residents living in other areas. Contribution/ Originality
This study is one of very few to investigate the four different types of residents’, on their perception of tourism impacts in a city of a developing country. The study found that the understanding of socio-cultural effects is diverse among residents. Business & Management » Journal of Tourism Management Research » Month: 03-2019 Issue: 1
Developing a Scale to Measure a Football Players Transfer Score
The aim of this study is to develop a scale that demonstrates the transfer score of a football player, with the help of metrics generated through network science. Six matches played Turkish National Football Team in the 2014 World Cup Qualifiers were analyzed with e-analysis soccer program. To obtain the network of the matches and the measurements of networks we used the open-source program Gephi. By taking into consideration the correlations between 11 network metrics, factor analysis was performed, and factor loadings were obtained. To determine the transfer score, as a measure of centralization: degree, weighted-degree and betweenness-centrality, and as a measure of contravention: eccentricity, 4 variables were defined. As a result of factor analysis, three variables were combined into a single component. The variance explanation value was found to be 90.611%, the internal consistency criterion was 0.66 and the transfer score value was calculated using the squares of factor loadings. The scale we developed will be able to determine the transfer value of a player, as well as the changes in the player's performance over time. Contribution/ Originality

The Influence of Strength and Power on Rowing, Ski Ergometer Performance
Ergometers have been developed as off-season or dryland training tools for sports such as rowing and cross-country skiing. These ergometers have recently been staples in the training methods for functional fitness athletes. Purpose: To examine the relationship between athlete strength and power with rowing ergometer and ski ergometer performance. Methods: Eight healthy college-aged participants, age 18-26 years volunteered to go through a series of strength and ergometric exercises while being assessed with a metabolic cart to measure gas exchange. The three strength measures were a maximal effort on bench press, back squat, and deadlift. A watt bike was also used to assess lower body power output. All strength tests were performed following the National Strength and Conditioning Association protocols. The ergometric performances on ski ergometer and rower were performed both using the Concept2 model with the damper settings at 10. Results: A significant relationship exists between strength and ergometer performance at both sprint and mid-distances. Conclusions: Athlete strength is a significant contributor to ski ergometer and rowing ergometer performance at 100-meter and 2000-meter performances. When considering training protocols for rowing and cross-country skiing, athletes and coaches should invest in addressing strength as a meaningful portion of the training effort.

Estimation of Suspended Sediment Load in the Ressoul Watershed, Algeria
Research Article
Author(s):
Journal: International Journal of Hydrology Research
Sediment load and its response to the variations of the hydrological elements are important to understand the phenomena of erosion. This study was fulfilled with the aim of developing a model to predict sediment load using sediment rating curve for the Ain Berda gauging station. The model was developed based on the available streamflow discharge and suspended sediment concentration data during sampled storm events over 39 year-period in the Ressoul watershed. Relationships between sediment concentration and water discharge were used according to single and rising-falling stage ratings to determine the best model for sediment load prediction. Additionally, a technique was devised to correct for log-transform bias on the sediment rating curves. The mean annual sediment yield during high and medium high flood events was 302 T km-2 yr-1. The high sediment loads in the study basin could be explained by the intensity of rain, the aggressiveness of the flows, the topography and the availability of sediments from hillslopes. The sediment load was dominated by winter and spring seasons accounting for 89% of the annual load. A high sediment supply in winter might confirm the intense geomorphic action caused by high intensity rainfall, low vegetation cover, and heavy machine activity in the agricultural fields. Following watershed management for local communities may bring multiple benefits. The adoption of suitable measures for soil conservation should reduce soil erosion and improve the livelihoods of the inhabitants. This study can serve as a reference for policymakers and planners. Contribution/ Originality
This study contributes on the existing literature on the estimation of suspended sediment yield using rating curve technique. The study outlines the analysis of some factors of erosion for estimating impacts of conservation methods on stream flow and sediment yield.

Foreign Direct Investment - Growth Linkage in Sub-Saharan Africa: Is Governance a Mediating Factor?
Research Article
Author(s):
Journal: International Journal of Business, Economics and Management
In sub – Saharan Africa, weak institutions and the rising concern for improved business environment offer considerable leverage for enhancing the effectiveness of institutional framework, capital inflows, and public investment efficiency. These have put SSA in the global spotlight in recent times. Hence, the study examines the mediating effect of governance on FDI – growth nexus in 35 SSA countries between 2002 and 2017 using panel data techniques (Pooled OLS, Fixed Effects, and Panel-Corrected Standard Error’ (PCSE) estimation) and the Dynamic One – Step Difference and System GMM. Results indicate that control of corruption, political stability and regulatory quality, including governance composite index, have a positive and significant effect on economic growth, suggesting that institutions have a salutary impact on SSA economies. The findings further show that FDI inflows adversely influence growth owing to insufficient absorptive capacity that could enhance FDI effectiveness in the region. More importantly, the pervasiveness of poor governance in SSA is identified as a critical case that undermines the development of the nexus between FDI and economic growth. Thus, the study suggests that FDI – growth linkage would be enhanced by promoting a strong institutional environment that offers a good mechanism for attaining the actual FDI spillover potential through a policy framework that points the path towards cost-effective measures in SSA. Also, there should be core investment policies across African countries that would induce the private sector in consolidating government efforts and resources aimed at improving international competitiveness by diversifying the region’s economies away from a protracted commodity – based. Contribution/ Originality
The study offers a sufficient basis of analysis that amplifies and consolidates FDI-governance-growth literature. It also addresses unresolved mixed conclusions arising from puzzling methodological issues through the use of efficient and robust estimation techniques. The paper provides a better understanding of the role of governance in FDI-growth nexus regarding Africa.

Research Article
Author(s):
Journal: International Journal of Education and Practice
The aim of this study is to examine the lecture method preferences of Ukrainian consumers of educational services. The study has observed two popular methods of providing educational services: the auditory method and the visual method. Research methodology included: information research; questioning and statistical processing of questionnaires; graphical representation of results and verification of statistical hypotheses. The sampling included two groups of students and one group of school teachers. It was statistically proved that Ukrainian students prefer the visual method of lectures but not the auditory method in availing educational services. Since the results are strongly significant, they have a great practical importance, recommending university teachers to use visual methods of lectures more than auditory while providing educational services. This will help them to adapt their lecture form and technique according to the needs and preferences of students as consumers of educational services. In addition, the results will also be useful to design and formulate training programs for teachers of Ukrainian Universities and making policy design for the Ukrainian Higher Education. Contribution/ Originality
This study is one of very few studies which have investigated preferences of consumers of educational services of the type of lecture method of providing educational services. The paper is a contribution to the first logical analysis of the preferences of university students and school teachers.
