Export demand estimates are important for meaningful export forecasts, planning, and policy formulation that can help improve the performance of the sugar subsector in Swaziland. This study estimated the determinants of export demand for Swazi sugar and measured the impact of the EU reform on Swazi sugar export demand. The study used panel data approach by using annual time series data between the periods 1997 and 2012. An LSDV fixed effects model was employed. Export price, Importer GDP and the EU reform were found to be significant in explaining export demand for Swazi sugar. These variables had coefficients -121.069, and -2.682, respectively, whose signs were against the priori expectation except for export price. The EU reform was found to have an overall positive impact to Swazi sugar export demand with coefficient of 120 816. The study also measured elasticities of the explanatory variables to the export demand of Swazi sugar. Export price, foreign income, producer prices and real exchange rate were found to be inelastic with elasticities of 0.35289, 0.00168, 0.04256 and 0.28572, respectively, for all the markets (SACU, EU, USA and COMESA) pooled together. Explanatory variables in the individual markets were found to be highly elastic. The study, therefore, recommended that Swaziland needs to take advantage of the EU reform and invest more on sugar production as it was not negatively affected. Swaziland also needs to negotiate for the quotas abandoned by those countries heavily affected by the EU reform. Contribution/ Originality
This study contributes in the existing literature by using demand function on the Swaziland Sugar Industry. This is the only study to be undertaken in Swaziland in relation to the Sugar Industry. Hence the study is original. Agricultural Sciences » International Journal of Sustainable Agricultural Research » Month: 03-2016 Issue: 1
Analyzing the Determinants of Achievements of Beneficiaries of Literacy Programs in Morocco: A Multilevel Analysis
This paper aims to assess the determinants of success of literacy programs in Morocco. This work uses hierarchical models. This specification provides opportunities to simultaneously analyze the impact of individual variables and taking into account the socio-spatial variations. The results show that the quality of literacy services, as measured by the total score, the level of information about the level of knowledge, is subject to variability. The analysis highlighted the diversity of factors that may be responsible for this variability. Some of these variables are related to the characteristics of the beneficiaries, other characteristics of trainers and logistical conditions in which the literacy process unfolds. Contribution/ Originality

Journal: International Journal of Geography and Geology
Anzali as one of the populated coastal cities in the Northern Iran, contains a particular type of marine sand which is worth to be investigated for many engineering practices. This particular sand is mainly composed of saturated fine grains and is highly prone to liquefaction phenomenon during seismic events. Geotechnical zonation of the subterraneous layers show that most of sandy sedimentary soils found below the surface in this area is formed by relatively clean and fine sand. In this research, the geotechnical characteristics of Anzali sand have been studied. It is done based on three sources of information, i.e. field studies, static tests and physical modeling by dynamic tests. In this regard, the overall zonation of this area has been carried out and the extent of the sandy area has been investigated. Anzali sand has been characterized by making use of a number of soil samples obtained from various parts on which, index tests have been carried out. Furthermore, based on laboratory shear tests and information gathered from in situ tests, the shear strength parameters and the critical limits for Anzali sand have been classified. Finally, large scale physical model tests were conducted to show the dynamic behavior of the sand under cyclic and dynamic loads and also the development of the excess pore water pressure during dynamic loading that could cause the liquefaction initiation. Contribution/ Originality
In essence, the paper’s primary contribution is to find or estimate Anzali Sand parameters which are required for prediction or analysis of liquefaction potential during seismic effects. This is done by a number of tests on samples extracted from locations in this area. Energy & Environmental Sciences » International Journal of Geography and Geology » Month: 10-2015 Issue: 10

Modeling a System of Rotating Biological Contactor (RBC) for Biodegradation of Phenol in Industrial Wastewater
A model for a 4-stage Rotating Biological Contactor (RBC) for the biodegradation of phenol from industrial wastewater has been developed using the mass conservation principles. The kinetics for biodegradation of phenol and oxygen utilization were obtained from literature under the same operating conditions. The systems of non-linear differential ordinary differential equations obtained were integrated numerically using the fourth-order Runge-Kutta algorithm adapted to a Visual Basic 6.0 computer program. Model predictions of 0.0505mg/l obtained for effluent phenol concentration, compares favorably well with the plant data of 0.05mg/l with a maximum deviation of 1.0%. A biodegradation of approximately 70mg/l at residence time of approximately 10hours, 56mg/l at residence time of approximately 8.5hours, 57mg/l at residence time of approximately 7.5hours, and 68mg/l at residence time of approximately 6.0hours with a constant oxygen concentration utilization of 0.087mg/l, were obtained from the first, second, third and fourth-stage respectively. Functional parameters such as retention time, rotational speed, respiratory coefficient and biomass concentration were simulated to study its effect with a view to obtain optimum efficiency. Contribution/ Originality

In Vitro Differential Effect of Nerve Growth Factor on Functional Parameters of Murrah Buffalo Spermatozoa in Low and High Fertile Groups
Aim of the present study was to examine the influence of in vitro supplementation of Nerve growth factor (NGF) on functional parameters of Murrah buffalo (Bubalusbubalis) spermatozoa from fresh semen, like, motility, plasmalemma integrity, acrosomal integrity, ATP concentration. Fresh semen samples (n=6) were washed in Tris buffer and divided into two equal parts (control and NGF groups). Only in the NGF group, NGF was added to a final concentration of 50 and 100 ng/ml. The samples were incubated at 37o C for different time intervals in TCM 199 medium supplemented with BSA and the effects were observed at 0, 30, 60 and 120 min of incubation. The experiment was performed in low (LF) and high fertile(HF) groups based on previous three years conception rate and taking cutoff value , below and above this value were categorized as LF and HF group. The mean concentration of the buffalo seminal plasma (n=12) NGF was 67.7±3.25ng/ml and 65.5± 2.76 in LF and HF groups respectively. The concentration of NGF in blood plasma was 83.5±7.82 and 68.6±3.82 in HF and LF groups respectively. The concentration of blood plasma NGF being higher (P<0.05) in HF group. With either dose of NGF in vitro significant effect on the total motility (P<0.05), progressive forward motility (P<0.05) was observed. It could be maintained in HF group till 120 min but in LF group it was restricted to 60 min when compared with their respective control. The functional membrane integrity did not differ significantly between groups (control and NGF treated) in both LF and HF groups with either concentration of NGF. The plasma lemma integrity was significantly less (P<0.05) at 120 min of incubation when compared with the initial value at 0 min of incubation. The percentage of acrosomal intact spermatozoa decreased continuously over a period of time in both the groups. As compared to 0 min of incubation, the significant (P<0.05) loss of acrosome was observed at 60 and 120 min of incubation in LF and HF control groups and NGF supplementation could maintain acrosome integrity in HF group for 60 min where as in LF group it could be maintained significantly only till 30 min of incubation when compared with the initial values of respective groups. Viability of spermatozoa was not significantly different when compared between groups with their respective control, However when compared at different time intervals, the viability of sperms in HF and LF supplemented groups was significantly different from initial values only at 120 min of incubation whereas in respective control groups the loss in viability was significant from 60 min itself. With respect to ATP concentration of spermatozoa in different groups it was observed that 100ng dose could increase the concentration of ATP in HF group significantly (P<0.05) at 60 min of incubation only with NGF in vitro when compared with its respective control. In conclusion, all the parameters decreased significantly at 120 min of incubation when compared with their respective initial values for all the groups. In HF group supplementation of NGF@50ng/ml could maintain functional parameters of spermatozoa for a greater duration of time when compared with LF or control group. Contribution/ Originality

Teachers being thinking human beings and not robots, they do not just implement the curriculum as designed. To improve Language Teacher Education (LTE) and English language teaching (ELT), general research in teaching language and on second language teachers, concerning their mental images, thoughts, and processes that they use while teaching have been carried out. These mental processes provide interpretive frames that teachers use to understand and approach their own teaching. The principles function like rules for good behavior or maxims. These maxims guide the teachers’ choice of instructional decisions. Analysis of teachers’ accounts of their teaching and lesson protocols reveal the nature of their maxims. The purpose of the study was: to examine the maxims that guide teachers in ELT, and to establish factors that influence the choice of teachers’ maxims in ELT for social transformation. It used ethnography research method. The research instruments used were: document analysis, informal interview, and observation. Findings reveal that teachers are guided by the maxim of ‘value addition’ which significantly affects the implementation of the curriculum. The teachers’ maxims are influenced by a number of contextual factors such as: the school administration, external examinations and Quality Assurance and Standards Officers. Teacher educators should train student teachers and design workshops for practicing teachers to improve their maxims of: planning, accuracy, efficiency and conformity to the designed curriculum. Contribution/ Originality
This study contributes to the existing literature on teachers’ maxims in English language teaching. The paper’s primary contribution is finding that teachers’ mental processes that provide interpretive frames which guide their approach to teaching are influenced by contextual factors and the maxim of value addition.

Gaboul Ahmed Faiz, Fais Bin Ahmed, Abdullah Kaid Al-Swidi
The main purpose of this study was to investigate the mediating effect of Market Orientation (MO) on the relationship between entrepreneurial orientation dimensions (EO) namely: Innovativeness, Proactiveness, Risk-taking and organizational performance (OP). The motivation for this study was driven by the inconsistent findings in the literature concerning the relationships between EO, and organizational performance. Due to the inconsistent results, a new research has emerged and this has prompted further investigation on the effect of other variables that may better explain the nature of these links. In the related literature, many theories have suggested that the compatibility between strategies, resources, and capabilities as the keys for success. Questionnaires were distributed to 400 Sections of the Libyan banks. 230 questionnaires were returned and used in the analysis using the PLS-SEM. The results of this study revealed that EO dimensions were positive and have also been proven to be significant predictors of organizational performance. More importantly, the results have also confirmed the mediating effect of Market Orientation on the relationships between EO dimensions, and organizational performance. Contribution/ Originality
This study contributes to the existing literature by examined the role of market orientation in maximizing organizational performance – specifically, its mediating role in the relationships of EO and organizational performance.
The study examined farmers’ vulnerability, perception and adaptation to climate change in Kwara State. Data were collected with the aid of structured questionnaire to elicit information from 120 food crop farmers selected through a multistage random sampling technique. Data were analyzed using descriptive statistics, fuzzy set approach and multinomial logit model. Results show that majority of the sampled farmers were in their productive age with about 26.6% had no formal education and were predominantly small scale farmers. The study revealed that majority (84%) of the farmers believed that temperature had increased while about 65.8% noticed that precipitation had declined. The farm household vulnerability assessment showed that the average multidimensional vulnerability indices for male and female farmers are 17.5% and 27.8%, respectively, while the average vulnerability index for all the farming households is 18.4%, implying that the intensity of vulnerability to climate change is higher in female farmers and that the whole sampled population is less than 50% vulnerability threshold. The econometric investigation revealed that education of household head, farming experience, land ownership, rainfall and temperature were the most relevant and significant factors that determined the farmers’ choice of adaptation strategies to climate change in the study area. The major barriers to adaptation include lack of information on adaptation methods, land tenure problem and inaccessibility to credit. Contribution/ Originality
The study contributes to the existing literature on climate change adaptations by taking into consideration the vulnerable poor farming households. The study adopted two methodologies to overcome the weakness of other studies. Gender attributes and their vulnerability intensity were investigated. The primary contribution is to guide strategy for future adaptations.

Gorham-Stout syndrome (GSS) is an uncommon disease characterized by massive osteolysis due to bone resorption associated with proliferation of blood or lymphatic vessels. Pleural effusion is an uncommon manifestation. We present a case report of GSS in a 46 year old patient admitted for bilateral serohematic pleural effusion and a review of the literature regarding GSS associated with pleural effusion. We analyzed 48 clinical casesfounded in English language literature concerning pleural effusion secondary to GSS. Patients affected by GSS manifesting pleural effusion are prevalently male with a large range of age. Pleural effusion is more frequently chylous (86%), but it can be also serohematic, transudative or bloody. Direct pleural involvement by the disease has been assessed only in some cases of chylothorax, otherwise the pathological process underlying the liquid production remains unknown. Pleural effusion is most of time bilateral. More frequently it conditions ingravescent dyspnea and when it is chylous it can determine malnutrition. No standard therapy has been established. In patients with relapsing pleural effusion several therapeutic approaches have been used: radiation therapy on mediastinum, pleurodesis, thoracic duct ligation, octreotide administration. Radiation therapy seems to be effective even when applied only on the bone lesions. Bisphosphonates and alpha-2b Interferon are useful to improve the multiple sites of disease, thanks to their systemic action. The papers considered report a short follow up time, during which almost 50% of the treated patients had no recurrences, but more or less 20% of the patients died. Contribution/ Originality
This study contributes to the existing literature by presenting the first case of bilateral serohematic pleural effusion in Gorham-Stout syndrome that was investigated with chest ultrasound and medical thoracoscopy bilaterally. Furthermore, this study provides the first review of clinical cases reporting pleural effusion secondary to Gorham-Stout syndrome.
