Abstract
This article, using the case of Midlands State University (MSU), Zimbabwe aims to unravel the perceptions of Tourism and hospitality management students towards foreign languages. The study of the students’ perceptions is an integral factor in the education of foreign languages as these students are the future workforce of the Zimbabwe’s tourism sector and beyond. It also aims at determining the benefits of studying foreign languages to both the students and the industry at large and the challenges students encounter when studying foreign languages. A survey was conducted on fourth year students who had already done Portuguese in their second year and currently doing French as foreign languages. A sample of sixty-nine students was targeted in May, 2015. The study revealed that most of the students had positive perceptions of studying French and Portuguese as part of their modules contributing to their academic achievement. The benefits of studying foreign languages were put forward as: employment benefits, memory improvement, improvement of communication skills, part of personal achievement, understanding of the new culture, networking and encourages mobility. However, fear, confusion, lack of confidence, limited financial resources as well as few hours allocated to French and Portuguese were highlighted as major challenges students confronted with in learning foreign languages.
Contribution/ Originality
This study contributes in the troubling of existing literature on foreign languages, specifically French and Portuguese, learnt at Zimbabwean universities meant to enhance service delivery in the tourism and hospitality workplaces. It prioritises the perceptions of fourth year students who combine both workplace experience and theory learnt in the classroom.

Journal: Review of Knowledge Economy

Export to    BibTeX   |   EndNote   |   RIS

Abstract
The economic structure of society is constantly changing, whereas companies were dependent on manual labor in the past, today they are dependent on the knowledge worker. Since that knowledge workers make up two-thirds of the labor force, the focus of strategic plans nowadays are to improve their efficiency. Currently, there is not any adopted method for evaluating the performance of the knowledge workers. But the fundamental change in the nature of the labor force necessitates this issue. This paper aims to develop a model for evaluating the performance of knowledge workers in an Iranian research center using structural equation modeling, therefore this is a descriptive study based on co relational and regression analysis. Results proved that among the various appraisal criteria, innovation is the most important and significant factor which is equal to 4.35 in average from 5 and collaborate on research projects as well as attending seminars are the least important criteria according to the respondents point of view.
Contribution/ Originality
This study originates a new model for knowledge worker's performance evaluation for an Iranian research center. The proposed model investigates the researcher performance through four aspects including executive, educational, scientific and research works. This model contributes in the existing literature of KWs performance modeling.

Journal: The Economics and Finance Letters

Export to    BibTeX   |   EndNote   |   RIS

Abstract
This paper examines the performance and risk sensitivities of Japanese ethical mutual funds vis-à-vis their conventional peers between 2005 and 2014, focusing upon the impact of the recent financial crisis. More specifically, in doing so, I investigate the aggregated performance and investment style of ethical and conventional mutual funds and allow for time variation in the funds’ systematic risk. The empirical results are consistent with the evidence of asymmetric performance before-and-after the structural change, which is identified by Bai and Perrons’ structural break test. The Japanese evidence supports the conjecture that any performance differential between ethical mutual funds and their conventional peers is statistically insignificant.

Managerial Judgement Versus Financial Techniques in Strategic Investment Decisions: An Empirical Study on the Syrian Coastal Region Firms

Research Article
Author(s): Oubay Mahmoud
Journal: International Journal of Business, Economics and Management

Export to    BibTeX   |   EndNote   |   RIS

Abstract
While there has been extensive research on the use of financial appraisal techniques [Pay Back (PB), Return on Capital Employed (ROCE), Internal Rate of Return (IRR) and Net Present Value (NPV)] in Strategic Investment Decisions (SIDs), little research has been conducted on the role of the Managerial Judgement factors (MJ factors) – past experience, intuition and own judgement - in the SIDs. In practice, many investments are undertaken on the basis of financial returns with little or no analysis of the growth options embedded in the proposed investments. Essential to considering these options in the SIDs is the deployment of MJ factors in the SIDs. This research draws on a 36-firm survey of finance directors in Syrian coastal region firms to set out the relative importance of the MJ factors and financial techniques in the SIDs. The findings from the survey show high usage of the MJ factors in the SIDs but not at the expense of the financial techniques usage which are used regardless of the MJ adoption in the SIDs. However, There is a tendency towards using MJ factors more than financial techniques for investments with growth options. There is no relationship between neither the ownership nor the sector with the MJ adoption. ROCE and PB are the most frequently used financial techniques.
Contribution/ Originality
This study contributes to capital budgeting literature through identifying the relative importance of the managerial judgement compared to financial techniques when assessing new investments, especially when these new investments have strategic and non-quantifiable returns. It shows the crucial role the finance managers can play using their past experience, intuition and own judgement in the strategic investment decision- making process.

Journal: Asian Development Policy Review

Export to    BibTeX   |   EndNote   |   RIS

Abstract
Mobile telecommunications service has exceptionally developed for decades in most part of the world and it recently becomes a widely used technology. Since the development of mobile telecommunications technology evolves in accordance with the regulatory policy and framework, Cambodia is facing some challenges due to the absence of regulations in telecommunications sector. Based on the ADB technical team, the draft of telecoms law is still under the review of the National Assembly and it should be discussed with the public. Therefore, this paper is to assess the costs and benefits of regulatory policies in telecommunications industry incorporating with the consumer perspectives on three factors, the economic efficiency, fairness and stability. With the stated preference method, the fairness is the first significant factor with the coefficient of 38.11% while the economic efficiency at 33.00% and the stability at 28.90%. The fairness is more preferable to be regulated at upper medium level. However, the regulatory intervention for improving the economic efficiency should be at lower medium level while it is required to have high regulatory policies for the development of mobile telecommunications service. In the context of Cambodia, the regulatory policy in mobile telecommunications industry should focus on the fairness, the economic efficiency and the stability respectively.
Contribution/ Originality
This study is one of very few studies which have estimated the costs and benefits of regulatory policy in telecommunications sector, by using the stated preference method which incorporates with the consumer perspectives. It is to ensure the development of the telecommunications industry and the protection of the social welfares.

Journal: Humanities and Social Sciences Letters

Export to    BibTeX   |   EndNote   |   RIS

Abstract
The Egyptian government and its legislators have been putting forth legislative amendments to its domestic laws that are controversial in relation to investment, tenders, bids, and investment guarantee as top priority. On one hand, they are doing this in order to encourage and reassure the foreign investors in Egypt, and on the other hand, they are likely facing psychological fears of international massive litigations. However, these legislative investment amendments could threaten and undermine the stability of inherited Egyptian jurisdiction systems and integrity. These amendments include providing avenues of escape of corruption and financial crimes through the reconciliations with the foreign investors who have been damaging the Egyptian economy and its citizens’ livelihoods. As the role, size, and impact of foreign investment grow worldwide. The mechanisms holding such entities accountable are actively diminishing. Unfortunately, the legal framework of foreign investment is aggressively shrinking the state’s role in regulating these foreign investment enterprises in Egypt, while challenging the very sovereignty and jurisdiction of the Egyptian court system to investigate allegations of violations committed by foreign investors. In effect, this results in absolute impunity by foreign investors in Egypt. Moreover, this trend of more legal privileges and the loose accountability to the foreign investors create a negative impact on Egyptian public interests and then on the Egyptian legal system as well as on the Egyptian Constitution. The aim of this paper, therefore, is to highlight the lawful deficiencies of the amended investment laws as well as its patterns trespass to the Egyptian Constitution. In addition, this paper brings out the implications of these violations on the inherited Egyptian legal system.
Contribution/ Originality
This paper contributes to existing literature in two ways; first, it critically analyzed the presidential decrees that amended some part of the Egyptian laws. Secondly, the study also evaluates the effects of these legislative amendments on the Egyptian legal system.

Journal: Journal of Empirical Studies

Export to    BibTeX   |   EndNote   |   RIS

Abstract
The literature argues that small businesses are highly dependent on bank financing due to their inability to access the capital markets. We paint a different picture in this paper that analyzes the demand of small hotel and restaurant businesses for bank financing in Turkey. The results of a countrywide survey done with the owners/managers of the businesses that were responsible for the financial affairs are used for the analysis. We find that the majority of the businesses in the sample did not make a loan application in the last three years. Moreover, the tendency of firms to apply for bank financing did not change with age. When asked whether their firm were in a position not to apply for a bank loan in the last three years even if they needed bank financing with the idea that the application would be rejected, nearly all the participants responded negatively. The majority of the owners/managers of the firms declared that their firm’s demand for bank loans would increase with lower interest rates and lower collateral requirements. On the other hand, firms that would have a higher demand for bank loans if there were a reduction in interest rates and collateral requirements were younger firms.
Contribution/ Originality
The paper's primary contribution is the finding that the majority of the businesses did not apply for a bank loan in the last years. The study documents that younger firms would to have a higher demand for bank loans if there were a reduction in interest rates and collateral requirements.

Journal: International Journal of Geography and Geology

Export to    BibTeX   |   EndNote   |   RIS

Abstract
Airborne gravity anomaly over parts of Niger delta basin of Nigeria has been interpreted qualitatively and quantitatively. The residual anomaly was obtained from the observed field data through a second order polynomial method and then enhanced by a filtering process. The qualitative interpretation of the gridded data reveals NS, EW and NE-SW trending subsurface structures. The inverse and forward modeling results show spherical and dyke-like anomaly structures at depths of between 1,090 m to 3,538 m, while the density contrast of formations identifies areas of  possible hydrocarbon occupation. The Euler deconvolution windowed solutions reveal depth to anomalous sources of between 2,000 m to 9,300 m for structural index of one, and depths of between 3,200 m to 10,600 m for structural index of two. The source parameter imaging reveals depth ranges of between 1,700 m to 10,600 m. The work reveals that the maximum depth to basement in the study area is 10,600 m.
Contribution/ Originality
This study contributes to the existing literature on the structure, stratigraphy and depths to basement information of parts of the southern Niger delta of Nigeria using airborne gravity data. The papers primary contribution is in determining the maximum depths to basement in this region as lying between 9,300 m to 10, 600 m.

Journal: International Journal of Business, Economics and Management

Export to    BibTeX   |   EndNote   |   RIS

Abstract
Tax revenue in Ethiopia has been low throughout the study period (1974 to 2013). Tax revenue in Ethiopia was below the average of sub Saharan African countries. The main objective of this study is to empirically examine the major determinants of tax revenue in Ethiopia for the period ranging from 1975-2013, using Johansen maximum likelihood co-integration approach. The result revealed that in the long run real GDP per capita income, foreign aid and industrial value added share of GDP positively and significantly affect tax revenue. However, inflation exerted a negative and significant influence. Whereas, in the short run Real GDP per capita income and inflation have negative effect, whereas industrial Value added share of GDP has positive effect on tax revenue in Ethiopia. The sign of real gross domestic product per capita income is contrary to the priori expectation. Moreover, the coefficients of the lagged error correction term (ECM (-1)) is significant and negative as expected, which imply the existence of economic or government forces that restore the long run equilibrium from short run shocks. Finally, the study recommends measures such as a boost in per capita income growth, structural transformations, introduction of new tax bases and efficient utilization of foreign aid inflow have to be considered by the concerned bodies so as to bring efficient tax administration and enhance revenue growth. Moreover, the government shall give a due recognition to the development of the industrial sector.
Contribution/ Originality
This study is one of very few studies which have investigated the relationship between sectoral and macroeconomic variables with tax revenue in Ethiopia. It contributes to the existing literature in the study of tax revenue in Ethiopia. It identifies important determinants of tax revenue using econometric analysis.

Abstract
Infertility is a worldwide health concern with dissimilarities in mode of presentation among couples.  It is the commonest reason for gynaecological consultation in central Nigeria.    Therefore there is need to appraise the clinical presentation of infertility and describe the manner of presentation by women in the region. Aim: To identify the mode of presentation and pattern of presenting complaints by women with infertility at a rural gynaecological outreach clinic. Method: A descriptive retrospective study at NKST Hospital Mkar-Gboko, north-central, Nigeria.  Clinic records of patients who attended the outreach gynaecological clinic over eight years (1st January 2005 to 31st July 2013) were analysed using descriptive statistics with Excel 2010. Results: Of the 1,926 women studied, 1030 (53.5%) complained of inability to conceive, and 941 (92.0%) folders met inclusion criteria. Women with primary and secondary infertility were 264(28.1%) and 677(71.9%) respectively.  The mean (±SD) age, parity and duration of infertility of the women were 31.5±5.9 year, 0.8±1.2, and 7 ±5 years respectively.  The predominant complaints were inability to conceive, lower abdominal pain, abnormal menstruation, lower abdominal swelling and vaginal discharge.  Majority of the women (55.0%) skipped inability to conceive as their chief complaint.  In past surgical history, 194 (20.6%) of the women had 234 abdominal surgeries.  On physical examination 538 (57.2%) of the women had no remarkable findings.  Abdominal scar (n=194, 47.0%), enlargement of the uterus (n=166, 40.0%), vaginal discharge (n=42, 10.0%) were common findings. Conclusion: Non acute lower abdominal pain is a common mode of presentation of infertility in this population.  The duration of marriage/age of last childbirth against the number of living children and contraceptive usage can be a clue to the woman’s desire.
Contribution/ Originality
This study documents that non acute lower abdominal pain is a common mode of presentation of infertility by women in central Nigeria.  The duration of marriage/age of last childbirth against the number of living children and contraceptive usage can be a clue to the woman’s desire and appropriate intervention.

Abstract
The transportation issue is one of the thematic priorities which give policy makers great inspiration and demand background. Today’s transport networks are leading the way in sustainable, efficient and safe mobility, increasing access to all regions. Large scale projects, infrastructures, networks, EU Cohesion policy’s nearly 22% fund support were mostly emphasized in this sense. This is also valid for candidate countries for Union. This paper discussed the case of Turkey, i.e. she is a candidate state for European Union, and benefiting from the financial instruments for funding regional development process as European Regional Development Fund, Cohesion Fund, European Social Fund, EU Solidarity Fund, IPA and Turkish Cypriot community, Turkey only benefits from the IPA program. This study was prepared in order to present a review upon the transportation projects within the regional development policy of EU. Today, the available member countries are part of a policy mechanism via being joined the mostly known transport projects as Baltic Sea, Interrag V-A sub projects, and Central Europe integration in transportation manners.  Those projects were also analyzed in order to show the inspiration themes for the future and today’s concepts and needs of Turkey to be fulfilled in the regional development politics on transportation issue. The number and budgets of transport themed projects and major projects and Turkish TEN-T and similar IPA supported projects were also evaluated in this study.
Contribution/ Originality
This study contributes in the existing literature about case analysis on how regional development policies were affected by macro transportation projects.

Journal: Journal of New Media and Mass Communication

Export to    BibTeX   |   EndNote   |   RIS

Abstract
Empathy is an important communication skill that has been shown to affect both individual knowledge acquisition and interpersonal relationships. How empathy develops and subsequently influences human interactions, and the consequences associated with those interactions, is the focus of this study. I examine the empathetic perceptions of upper division undergraduate college students and integrate their lived experience with empathy related factors discussed in the literature to describe a model of empathy development. The results suggest people can learn to communicate more efficiently and effectively by developing empathy in them-selves as well as in other people. More specifically, the findings indicate empathy is a function of several internal and external elements beyond biological and environmental antecedents. Respondents associated four internal themes with increased empathetic understanding: emotional sharing, positive relationships, mutual regard, and personal genuineness. Respondents also identified three external themes that moderated the strength or direction of their empathetic perceptions: the perceived similarity, relevance, and availability of the person being observed. Each of these seven themes is explicated in order to discern how one person might better empathize with another or enhance the ability of other people to empathize with them. The practical implications for more empathetic communication are explored, as are suggestions for future research.
Contribution/ Originality
This study documents how empathy develops in human beings and the communication consequences associated with such empathetic development.  The paper provides a review of previous empathetic research before surveying individuals about their personal empathetic experience. Those interviews are analyzed and reveal four mediators and three moderators of empathy development as well as relate a variety of benefits associated with empathetic communication. A synthesis of empathy literature is used in conjunction with survey findings to propose an integrative model of empathy development.  The theoretical contributions of this paper may be useful as a basis for future communication research and applied communication applications.

Abstract
The performance of Malaysian students in Trends In Mathematics and Science Study (TIMSS) was not up to par. The rank of Malaysian students in the assessment is the bottom one third, not the top. However, there are still a very low number of studies have been conducted with the TIMSS finding. This study intends to a) confirm items reliability included in the study( for Malaysian students), b) confirm the significance of latent exogenous constructs toward latent endogenous construct and c) confirm the type of mediation exist in the structural model. Secondary data obtained from TIMSS 2011 database has been used in this study. Items have been grouped into latent exogenous constructs; school, teacher, motivation, self-confidence; latent mediator construct; attitude and latent endogenous construct; achievement. From the analysis, it is found that only a few items included are reliable to represent respective constructs. Furthermore, it is explored that all latent exogenous constructs have significant direct effects toward latent endogenous construct. And lastly, it has also been confirmed that, all latent exogenous constructs except school latent construct have indirect effects toward endogenous latent construct; students’ achievement through the mediator latent construct; attitude.

Abstract
Flour from three plantain cultivars (Agbagba, Cadaba and French horn) commonly grown in Nigeria were investigated for their particle size, bulk density and thermal properties. The results showed that Agbagba cultivar had the least particle size (10.04%) at 125µm sieve size and significantly increased to 29.45% at 180µm sieve size. Cadaba and French horn plantain cultivars showed a particle size of 56.54% and 36.20% at 125µm sieve size, respectively and decreased significantly with increase in sieve sizes. The bulk density ranged from 28.62% to 30.50% and showed no significant differences between the cultivars. The moisture content ranged from 7.65% (French horn) to 8.7% for (Cadaba) and showed no significant difference (p > 0.05). Also, there were no significant differences (p > 0.05) observed in specific heat capacity, thermal conductivity and thermal diffusivity between the cultivars studied. The data thus obtained showed that chemical composition of the cultivars may influence thermal properties and this will serve as a useful engineering tool for the design and development of sieves and dryers for plantain flour.
Contribution/ Originality
This study provides necessary information that can be used in the design of dryers for plantain flour. This study also showed that proximate composition rather than differences in cultivars influenced thermal properties.

Abstract
Higher Education (HE) is becoming highly competitive today and therefore, Institutions of Higher Learning need to look closely at improving their customer service strategies. Consumers in the education sector are now much more aware of what exactly they want; and therefore the demand for these services is similar to what they demand for commercial businesses. Customer service has become the centre of management activities which constitutes the basis of competition in the higher education sector today.  Universities and colleges should begin by becoming proactive not reactive in the marketing of their services. The Customer Service Quality model has been widely used to study service excellence in a number of service industries; education inclusive.
Contribution/ Originality
The study documents the performance of higher institutions of learning with regard to improving quality and increasing productivity. This is seen through institutional policies and structures to deliver the services promised, recruiting staff competent enough and responsive to the dynamic education sector and designing the environment to fit an academic context.
