Abstract
Making a differential diagnosis between schizoaffective disorder  with major depressive episode and paranoid schizophrenia is difficult. The patient is at the threshold of neurotic versus psychotic, the intensity of ideation phenomenon being very high and specific to both disorders, it is required an assessment based on life and disorder history information, but also the emotional presence of the patient in the clinical interview. In this case study we suggest a literature comparison but also an evaluation profile of the disorder, marked by a psychiatric illness in which the person shows both affective symptoms (depressive or maniac) and symptoms of schizophrenia (such as delusions, hallucinations). Hypothesis: symptoms of the patient are oscillating between paranoid elements (paranoid schizophrenia) and affective elements (schizoaffective disorder). These oscillations are based on a fragile Ego structure with cognitive rigidity. The study outlines an immature-dependent personality profile, based on interpretativity, with passive-aggressive elements, hypersensitivity, psychotic operation and through psychotic elements manifested in the past (auditory hallucinations, as voices). Also, the basis of the transfer and counter-transference elements identified, the emotional resonance is low, with a risk of psychotic decompensation. Conclusions: Depressive schizoaffective disorder is characterized by presence of both depressive and schizophrenia symptoms in the same time period. Depressive symptoms includes: depressed mood, reduced interest, sluggishness, low energy, difficulty concentrating, insomnia, feelings of despair. During the same episode are present symptoms of schizophrenia: hallucinations, delusions of control, state of hyper-vigilance, delusions injury. Clinical examination cannot be a chance encounter because the history of mental suffering tight interfere with subject's essential history in that it creates a gap and that subjectivity psychiatric symptoms inferred immense emotional and personal participation of the subject.

Abstract
This study assessed government feeding programme on improved nutritional health status of secondary school students in Maiduguri, Borno state, Nigeria. Objectives and corresponding research questions were used in the study. The research design adopted for this study was survey research method. The target population for this study comprised of day public secondary schools in Maiduguri, Borno state, with a total population of nine thousand three hundred and thirty eight (9,338) students. Five public secondary schools were selected using purposive sampling technique. The sample of 934 students was selected using simple and stratified random sampling techniques. A self- developed questionnaire on government feeding programme among students in Maiduguri, Borno State was the instrument of data collection. The response mode for the instrument was a modified four(4) points Likert type scale with a response mode of strongly agree, agree, disagree and strongly disagree. Descriptive statistics of frequency counts, and percentage scores were used to answer the research question, while Chi-square was used to test the hypotheses at 0.05 level of significance. The results showed that the school feeding programme improved the nutritional health status of the students. Based on the findings of the study, it was recommended that Government should employ qualified food scientists, nutritionists, dieticians and caterers to assist in running the programme and to make them responsible for the purchase of needed food items to be cooked in schools. Furthermore, Government should also encourage more international donor agencies like the International Non-governmental organizations to come in with more improved varieties of school meals to increase the nutritional health status of the internally displaced students in the society. School feeding programmes should encompass both public and private primary and secondary educational institutions across the country. Feeding should be well guided by a menu which reflects the nutritional need for energy and micronutrients body requirements of the particular geographical area.

Abstract
Background and Purpose: There is currently no culturally appropriate instrument to assess Nigerian physiotherapists’ knowledge and attributes of professionalism.  This study sets out to develop a psychometric instrument to assess the knowledge and attributes of professionalism of Nigerian physiotherapists, and to investigate the instrument's readability, stability, and internal consistency. Methods: A Professionalism Inventory with eight demographic questions, ten knowledge of professionalism questions and sixteen attributes of professionalism perception-based statements was developed. The attributes of professionalism scale assess clinical competence, a spirit of inquiry, accountability, autonomy, advocacy, innovation and visionary, collegiality and collaboration, and ethics and values. The Inventory was completed on two occasions, after two-week interval, by 91 Nigerian physiotherapists. Results: The Inventory’s average grade reading level was 10. The intra class correlation coefficient (ICC 3, 1)  for the knowledge of professionalism scale ranged from “moderate” (0.421, p<0.001) to “substantial” (0.770, p<0.001). The Kendall's coefficient of concordance for the attributes of professionalism scale ranged from “fair” (0.368, p<0.001) to “moderate” (0.547, p<0.001). The Cronbach alpha for the knowledge of professionalism scale was “almost perfect” (0.813, p<0.0001); and “substantial” (0.780, p<0.001) for professionalism attributes scale.  Conclusion: The knowledge and attributes of professionalism scales are stable and internally consistent. The availability of this psychometric instrument will promote studies of professionalism in physiotherapy.
Contribution/ Originality
This study is the first psychometric instrument developed to assess Nigerian physiotherapists’ knowledge and attributes of professionalism and also the first to document the instrument's readability, stability, and internal consistency statistical properties.

Export to    BibTeX   |   EndNote   |   RIS

Abstract
This paper explores the determining of which factors/variables, and the optimal levels of these factors that lead toward successful online posts in a B2B context. Using real data from a software development company’s official social media outlets, data made available only to the authors, we conducted a fractional-factorial design with two dependent (output) variables, which were measures of success: number of impressions, and number of actions. We examined the impact of six independent variables (“factors”) and some selected interactions of these factors on the two output measures. The factors are: day of post, time of day of post, presence of an image, presence of a hashtag, length of the message, and specific channel used. Three of the six factors were significant when analyzing number of impressions, while none of the factors made the 5% significance level when analyzing number of actions.
Contribution/ Originality
This study is one of the very few studies which have investigated the factors that determine the success of online posts in a B2B context. Also, it is the first paper to investigate this issue using a fractional-factorial design.

Abstract
This study was designed to investigate the prevalence of prediabetes and the associated risk of kidney disease in Nnewi, Nigeria. A total of 277 apparently healthy subjects (73males and 204 females) who were willing to participate were recruited. Anthropometric indices and blood pressure were measured using standard methods while the demographic data and dietary pattern of subjects were obtained using a well-structured questionnaire.  5mls of blood was collected from eligible subjects (20 prediabetes and 20 non prediabetes ) and dispensed in fluoride oxalate and plain containers for glucose, creatinine (Cr), Urea(Ur), Na+, K+, Cl-, and HCO3- estimation respectively using standard methods. The result showed a prevalence of 7.2% prediabetes in the population. BMI was significantly higher in prediabetes than the control groups (39.4±5.8 vs 29±4.4kg/m2; P>0.05). Again, significant increases in the prediabetic values of FBG (117.54±16.84 vs 83±16.84mg/dl; P>0.05) than the control group were observed. The SBP (128± 11.26 vs 120±2.2mmHg; P>0.05) and DBP (92±4.43 vs 60±5.3mmHg; P>0.05) was also higher in prediabetic groups. Interestingly, result showed  no significant difference between the renal parameters in prediabetes and non prediabetes (p>0.05). The study therefore, suggests that the major determinant for predabetes in the study population may be hypertension and obesity whereas kidney function was not impaired.
Contribution/ Originality
This study documents the Prevalence of Prediabetes and the associated risk of kidney disease in apparently healthy individuals in Nnewi, Anambra State, Nigeria.

Abstract
The most accepted Multifactor Leadership Questionnaire (MLQ) is heavily applied to measure the transformational leadership in private sector and central government organizations than provincial council organizations in Sri Lanka. Thus this paper describes the development of a 21 item instrument for assessing transformational leadership in provincial council organizations in Sri Lanka with special reference to the western provincial council. To do so, both qualitative and quantitative methods were applied in three fundamental stages recommended by Churchill (1979). Initially a qualitative research was undertaken in five ministries in the western provincial council within Colombo district through interviews with 15 senior and middle level administrative officers from different back grounds which produced 21 items with four factors emerged. These 21 -items were included in a questionnaire and quantitative study was undertaken with the same respondents who were currently involved in the service in the Western Provincial Council. 60 questionnaires were distributed and 56 questionnaires were returned and found to be useful 56, which represents a 93% response rate. More than half (52) of the respondents were female between the age of 40-55. To ensure the reliability and validity of the measures of transformational leadership construct, mainly reliability test, factor analysis, was used. Finally, 21 items were deducted into 10 items and a new scale was developed to measure the transformational leadership in public sector organizations with three dimensions idealized influence, inspirational motivation, intellectual stimulation and. Regarding the limitations of the study in this respect, only the senior and middle level managers were considered. The sample size was 60 and it was selected only from the western provincial council with the use of purposive sampling technique. Further studies with large sample size which covers the all provincial councils using newly developed scale to measure the transformational leadership and replication studies with other organizations would be useful for further generalizations of the newly developed scale.
Contribution/ Originality
This study is one of very few studies which have developed scale for measuring transformational leadership in the public sector organizations in Sri Lanka. Such a study is significant that its leadership development is at crucial stage.

Abstract
Breast cancer is the most common malignant tumor among women. The objective of this research is to evaluate the specificity, sensitivity, and accuracy of BSGI, DC, and WE-MRI in the diagnosis of breast benign and malignant breast tumors. 228 female patients have participated in this observational research. The age was ranged from 31-68 years (mean age 42.37± 8.14 years) with suspicious breast lesions according to physical and imaging examination (mammography and/or ultrasonography). Moreover, women, who have suspected local regional recurrence after resection of malignant breast tumor and who were suspected to have tumor residual following chemotherapy or radiotherapy were also included. All patients underwent breast specific gamma imaging, DW-MRI, and DCE-MRI examination, and the results of breast MRI were compared with the histopathological results that were used as the standard diagnostic method. In this research, 111 women were found to have breast lesion. All breast lesions were undergone histopathological analysis using needle biopsy and/or excisional biopsy. Also, the results of the pathological analysis were correlated and confirmed with ultrasonography and mammography. The pathologic analysis confirmed that 76 (68.5%) of 111 lesions were benign breast lesions and 35 (31.5 %) of 111 were malignant breast lesions. The results proved that BSGI had the best results for the detection of breast lesions (sensitivity 96.7%, specificity 93.6 % and accuracy 94.8%) as compared with DCE-MRI (sensitivity 92.3%, specificity 85.6% and accuracy 88.2%) and diffusion weighted imaging (sensitivity 94.1%, specificity 88.5% and accuracy 91.4%). The research stated that BSGI is the most appropriate diagnostic tool for breast lesions.
Contribution/ Originality
This study documents that Breast Specific Gamma Imaging (BSGI) is the most suitable diagnostic tool for benign and malignant breast tumors. Specifically, the study has contributed in identifying the specificity, sensitivity, and accuracy of BSGI in the diagnosis of breast lesions and tumors.

Abstract
Measurement of wood density in Congo Basin forests are needed to reduce uncertainties on estimations of carbon stocks. The purpose of this study was to test vertical variation and temperature variation (80 °C, 105 °C) effects on wood density of species in a semi-deciduous forest of eastern Cameroon. Wood samples were collected on felled trees, at the base, middle of the trunk and on the branches in plots of 10 m x 10 m for trees <5 cm diameter, of 20 m x 10 m for trees with diameter between 5 and 10 cm and, of 20 m x 250 m for trees with diameter ? 10 cm. 162 trees with diameter between 1 cm and 146 cm were used. The highest wood density (0.912) was found in Ficus sp. and lowest (0.295) in Enantia chlorantha. Using 80 °C as temperature to estimate wood density increased the value of about 10% when compare to the reference temperature of 105 °C. A significant difference was observed between wood density of the base and the top of trees studied. 10 species did not have wood density reported in the Global Wood Density database. This study recommends further research on wood density to cover as many tree species as possible in the Congo Basin.

Valuating ecosystem goods and services is expected to raise public attention to their importance and may trigger support for a suitable conservation strategy. This paper assesses how the community forest ecosystem functioning connected to human wellbeing and what is their monetary value. To answer these questions Kalika community forest of Dhading district, central Nepal was selected since it was rewarded by DFO as the best CFUG in Dhading in 2014. This study presents the results of an attempt to estimate the economic value of goods and service provided by the community forest. Market price method was used for estimation of provisioning goods, productivity method for supporting services, religious value through donation collection from the temple as cultural services and avoided damage cost for the regulating services and secondary data from the community forestry operational plan provided by DFO was also used for the estimation of provisioning goods. The economic value from the ecosystem functioning of the forest was approximate $441,739 per year with an average of $2265 per hector per year. The value of carbon sequestration was estimated high as $1342 per hector per year and the economic value of the cultural services was very low as compared to other but have a greater role in forest conservation. At last this study discusses the importance of outcome for sustainable forest management strategy and suggests some way forward.
Contribution/ Originality
This study is one of very few studies which have investigated the economic value of the specific community forest of Dhading district, Nepal. The paper documents the important information of the quantified monetary value of community forest resource that is paramount for the sustainable conservation and management of forest.

Journal: International Journal of Hydrology Research

Export to    BibTeX   |   EndNote   |   RIS

Abstract
Changes in climatic conditions have greatly affected surface runoff and stream flows both at local and global scale. This has led to adverse effects on surface run off and climatic system as a whole. Research on these hydrological changes at basin scale is of great importance to the water managers for the future planning and management of water resources. In this study, a Hydrological simulation model (HYSIM) was used to simulate runoff and quantify the effects of climate variability on runoff within the area of study. The model was calibrated and validated giving a coefficient of determination (R2) of 0.923, an RMSE of 0.56 and a BIAS of 1.697 respectively. The future climate of the catchment is projected to be warmer and, with less confidence, wetter as simulated using the IPCC scenarios. However, stream flow could increase by between 1.2% on the lower case to 4.5% on the higher case under these projections. There is therefore need to prepare for the increased runoff as it would affect the agricultural sector, industry, urban communities, as well as the environment.
Contribution/ Originality
This study documents the effects of climate variability on run off in Thika river basin and further simulates future possible occurrences using the Hydrological simulation model (HYSIM).

Abstract
The aim of this study is to eliminate the alkaloids from Kordala (Maerua  pseudopetalosa) by soaking  process and examine their effect on nutritional value, protein digestibility and anti- nutritional factors. The seeds were soaked in water for seven days with water changed daily. The proximate composition, protein digestibility, minerals composition, anti-nutritional factors and amino acids profile were examined. The results obtained showed that soaking decreased protein content (from 21.67 to 11.64 %), ash (from 2.9 to 0.3%), fat (from 1.78 to 1.05%), polyphenols (from 170.82 to 160 mg/100g), phytic acid (from 743.5 to 588.9 mg/100g), minerals and amino acids content also decreased. The process increased moisture content (from 8.3 to 9.62%), fiber content (from 1.36 to 4.27%), total carbohydrates (from 63.99 to 73.12%) and protein digestibility (from 58.4 to 68.1%) for raw and soaked seeds, respectively. Comparing these values with recommended dietary allowances, the results indicated that Kordala (Maerua  pseudopetalosa) seeds could be a good supplement source for some nutrients.
Contribution/ Originality
The present study is one of the first reports concerning investigations on the nutritional values of Kordala (Maerua pseudopetalosa) and studding the role of  soaking on the removal of bitter taste in Kordala, which used in Sudan as famine food.

Abstract
The primary purpose of this study was to obtain empirical evidence and provide a methodological alternative for helping understand how simulation serves to learning. Well-structured system design and unstructured learning implementation bring complexity to dealing with learning in total enterprise simulation, specially, how to investigate learning emanated from the simulation game’s structure and decision-making requirements has studied very few. Due to the multiple aspects of individual learning situation and the inevitable structural design differences in simulations, student authored reports were used as data source to analyze the connections of learning-performance based on means-ends theory and the model was constructed with the components, namely Attributes, Consequences, and Values. With limitations of research, the study provides practical evidence and student insight into logic and structure of the simulated firm experienced, as well as demonstrates the use of means-ends approach for research on the issue of simulation-based learning and performance.
Contribution/ Originality
The paper contributes the first means-ends analysis of the connections of in-class simulation-based learning-performance by using the learning setting and participant-authored reports. Contrasted with previous studies which were essentially oriented in product/service decision-making, this study was built on the efforts to enhance the understanding of how the virtual management practices contribute to generation of personal values, rather than to focus on simulation system’s external validity.

Abstract
Climate change is happening at a great speed becoming gradually perceived as most challenging impact of the world that life bearing organisms on earth ever sense. The study identified determinants of farmers’ engagement in non-farm activities as copping strategies to climate change in Merti, Arsi zone, Oromiya Regional state, Ethiopia. The studies also carried out to investigated gender differences in perceiving climate change, assess non-farm activities practiced by farmers in response to climate change and describe the determinant factors that influence farmers’ engagement in off-farm income source in the study area. The study followed a multi-stage sampling procedure. Both purposive and random sampling procedures were used to select sample Kebeles and households, respectively. Data collected from 191 sample households was used in this study. Descriptive statistics were performed to assess farmers perceptions and the types of coping strategies used were small-scale trade activities, handicrafts/craftsmanship and engagement in labor intensive salaried work, while the multinomial logit model (MNL) was used to identify factors influencing farmers coping strategies to climate change whereas age, sex, family size, agro-ecological locations (highland and midland), perception of climate change were the determinant factors favoring or inhibiting the decisions of farming households engagement in non-farm activities as climate change coping strategies.
Contribution/ Originality
This study is one of very few studies which have investigated determinants of farmers’ engagement in off-farm (non-farm activities) in Merti in undertaking possible climate change response mechanisms at the smallholder farming household level. The research will give baseline information for other researchers, practitioners, development actors, policy makers and research organizations by assessing and assembling existing information about the factors affecting farmers engagement in off-farm based activities as coping strategies in case of unexpected failure in agriculture produces.

Abstract
Foresight is among the key topics in natural resource protection for sustainability of rural settlement system. In foresight of land cover evolutions, identification of factors affecting the evolutions is of paramount importance. In the present research, in order to undertake foresight and sustainable land planning in rural districts in East of Guilan as a special ecologic zone encompassing 744 villages, principle variables were collected via a questionnaire using Delphi method with the help pf experts, followed by calculation of significance factors. A total of 93 variables were found to affect the changes in land cover within the study area at local, regional and national scales. Among these, key variables were identified utilizing MIC-MAC Software. In order to develop scenarios by a 20-member expert panel, 19 key drivers of the changes in land cover were homogenized and 9 primary descriptor were defined. For each descriptor, three variant qualitative component were prepared, which described all possible cases from the most critical case to the most desired one. In the next stage, with the help of cross-impact balance matrix and Monte Carlo simulations in Scenario Wizard Software, a total of three scenarios with 15-year horizons were obtained based on maximum consistency. Finally, based on the maximal effectiveness on protection of natural land cover and continuation of sustainability, the obtained scenarios were designated as balanced ecologic changes, relatively balanced ecologic changes, and imbalanced ecologic changes.

Abstract
21st Century has marked high velocity of data generation not only in terms of size but also in variety. Analyzing large data sets with different forms is also a challenging task. Data Mining is regarded as efficient method to extract meaningful information as per user requirements. But considering the size of modern data, traditional data mining techniques are failing. Clustering can be regarded as one of the most important technique to mine the data by splitting large data sets into clusters. The paper’s primary contribution is to provide comprehensive analysis of Big Data Clustering algorithms on basis of: Partitioning, Hierarchical, Density, Grid and Model. In addition to this, performance comparison of algorithms is performed on basis of volume, variety and velocity.

Abstract
Culture is not a new concept within the social sciences. In fact, culture has been widely discussed for years to investigate how it has evolved and how it still affects human communication. The aim of this article is to introduce the concept of culture and illustrate its relevance in key theoretical discussions and debates in the social sciences. Also, it aims based on secondary research evidence to highlight how differing cultural factors affect learning and assessing in higher education. The paper concludes that it is essential for assessors to consider the unique cultural characteristics when assessing their students’ performance.
Contribution/ Originality
This study contributes in the existing literature on the role of culture in education by focusing on assessment. It is one of very few studies which suggests that assessing students’ performance should not take place independent of cultural particularities and sets the ground for designing alternative, culturally responsive assessment tools.
