Research Article
Author(s): Kamilia Loukil
Journal: Review of Knowledge Economy

Export to    BibTeX   |   EndNote   |   RIS

Abstract
This paper aims to measure efficiency of R&D spending in ten emerging countries. We estimate two stochastic frontier models where human and physical resources of R&D are the inputs employed to produce an output: patents in the first model and scientific publications in the second model. Empirical evidence shows that scores are higher for publication oriented efficiency than patent oriented efficiency. Moreover, our findings suggest that innovative countries, those with high R&D intensity, are not necessarily efficient in the use of their resources and vice versa.

Nano Formulations of Natural Compounds for Enhanced Delivery

Research Article
Author(s): Zahangir Alam
Journal: Journal of Diseases

Export to    BibTeX   |   EndNote   |   RIS

Abstract
Natural products were always the key elements in ancient history that are promising to treat various diseases including cancer and prevent any health disorders. They have seen a breakthrough since they were used in cancer chemotherapy and prevention with selective phytochemicals. Fruits and vegetables contain nutrient constituents that are bioactive in disease states. Extensive in vitro and in vivo research data is available to prove their efficacy. While few compounds have successfully transitioned to the clinical trials, few of them are still facing problems due to their poor bioavailability and lack of targeting. The lack of efficacy in human studies can be attributed to the complexity of the biological system and complexity of food. In recent years, identification of molecular targets made it necessary to develop efficient formulations for delivery. Nano formulations such emulsions, nanoparticles and nano vesicles are few of the advancements that showed promising faith in natural product chemotherapy. This paper reviews few of the techniques employed for natural compound delivery which can be applied to various compounds.

Research Article
Author(s): Dehkhoda S., N. Arian Pour, R. Roozegar
Journal: Journal of Diseases

Export to    BibTeX   |   EndNote   |   RIS

Abstract
In this study the effect of placing subcutaneous drain in the incision site of obese patients undergoing bariatric surgery, on the rate of incision site infection was evaluated. 200 obese patients of both sexes included in the study on the basis of the inclusion and exclusion criteria. They were divided into two groups on the basis of their accessibility. For patients belonging to group II (study cases), subcutaneous drain was placed at the incision site. Follow up of the patients shows subcutaneous drain placed at the incision site reduces the rate  of  infection up to 2% which is significantly lower than the infection rate among patients for whom drain was not placed (P<.05). In spite of emphasis to use sutures, drains and foreign bodies only with adequate indications to avoid surgical site infection and based on the merits of employing drain in evacuating the collected material to prevent infection, we recommend the use of subcutaneous drains in obese patients as incision infection may lead to longer hospitalization or readmission. As higher treatment expenditures and higher mortality rate are the consequences of infection, every effort to reduce the consequences rates following bariatric surgery in obese patients is valuable and advisable.

Abstract
This paper empirically demonstrates the possibility of setting up an optimal pollution tax under imperfect markets and international trade in a domestic economy. The model illustrates a situation of partial equilibrium characterized by imperfect competition among domestic producers, where the domestic good is used as an alternative for an imported polluting commodity. In this paper, we bring in the possibility that the domestic firms can introduce innovative ideas through investment in R&D. The result shows that the optimal pollution tax under domestic economic distortions is a function of a ‘domestic production effect’ and a ‘pollution effect’. The paper concludes that when the firms execute R&D expenditures, the optimal policy adds an ‘innovative effect’, which captures the change in welfare coming from a reduction in total costs and this lead our results to a win-win situation.
Contribution/ Originality
The paper contributes in the existing literature by illustrating the case of partial equilibrium characterized by imperfect market among domestic producers. It introduces innovative ideas through   the incorporation of investment in research and development. The paper concludes that under a win – win situation optimal environmental policy represent a policy tax.

Abstract
In order to evaluate cassava roots yield of two varieties at three harvesting dates and assess the effect of harvesting date on physico-chemical composition of roots and quality of gari and baton de manioc, a study was done.  Cassava roots of a popular variety (local white) and the improved variety 8034 were harvested in small holder farmers’ fields in the mono-modal humid forest zone and the bimodal humid forest zone of Cameroon. At harvest, the yield was evaluated, the physico-chemical composition of roots evaluated and a sensory test carried out on gari and baton de manioc after processing. Results showed that harvesting date has an effect on the cassava roots yield, for both local white and variety 8034. Cassava yield varied according to agro-ecological zones, with higher yield in the mono-modal humid forest zone than the bimodal humid forest zone. The nutrient content in cassava root varied with the variety and age of roots. There was an increase with the age of roots for K, P and dry matter content for the variety 8034. With the local white variety, there was an increase in total N and dry matter content. In contrary, there was a gradual decrease of percentage Mg, K, Na with the age of cassava roots for the variety 8034.Baton de manioc obtained from variety 8034 at 10-12 months and gari obtained from same variety were scored the highest global quality.

Journal: International Journal of Management and Sustainability

Export to    BibTeX   |   EndNote   |   RIS

Abstract
Within the context of research on person-to-organization fit, it is suggested that the better the match between individuals’ attitudes, values, knowledge, skills, abilities and personality with the organization, the higher the individual and organizational outcomes will be. In this perspective, this research assesses that as the match between an entrepreneur’s personal characteristics and the requirements of being an entrepreneur gets better, the enterprise is thought to be more successful. Especially to the extent that the entrepreneurs are better off on a number of distinct dimensions of individual differences (i.e. self-efficacy, ability to recognize opportunities, personal perseverance, human and social capital, social skills and innovativeness), person-entrepreneur fit will be better and consequently the success rate will be higher. From this point of view, this study tries to find out how personality traits affect entrepreneurial intentions. This framework offers potentially valuable new ways of assisting entrepreneurs in their efforts to exploit opportunities through establishing new ventures. The results indicate that self-efficacy, ability to detect an opportunity, personal perseverance, human capital, social capital and social skills positively affect entrepreneurial intentions.

Export to    BibTeX   |   EndNote   |   RIS

Abstract
The study assessed promoting climate change adaptation measures for improving productivity among smallholder farmers in Taraba State, Nigeria. Interview schedule/questionnaire was used to collect data from a sample of ninety (90) respondents used for the study. Data were analyzed using factor analysis. Findings indicate that major effects of climate change among smallholder farmers were named based on the items loading for factors 1, 2 and 3 as food security, poor quality of produce and soil conservation effects, respectively. Factor analysis of variables with regards to climate change adaptation measures practiced by smallholder farmers based on the item loadings were named factors 1, 2 and 3 (agronomic practices, farm inputs and production measures, respectively). Variables which loaded high under agronomic practices include practicing of mulching (0.776), planting early maturing varieties of crops (0.643), early harvesting of matured crops (0.604) and adjustment of planting dates (0.542). Loadings under farm inputs were planting of cover crops to reduce loss of water from the soil (0.794), use of organic manure (0.794), practicing bush fallowing to increase soil fertility (0.743) and planting of improved varieties of crops (0.630). Production measures comprised value addition of farm produce (0.647), use of high yielding varieties of crops (0.630), practicing mixed cropping to guard against crop failure (0.577), practicing zero tillage (0.472) and erection of dams for storing water (0.464). Constraints to climate change adaptation measures among smallholder farmers were grouped into infrastructural, labour and fund-related problems. Efforts are highly needed in cushioning the effects of climate change by the stakeholders such as the government at all levels, extension agencies, research institutions, metrological institutes, disaster management agencies, higher institutions, local farmers and others by giving out first hand information on weather forecast so as to know the right and best time to plant and harvest crops. It also highlights the need for provision of adequate infrastructure to enhance easy adaptation to climate change as well as increasing productivity.
Contribution/ Originality
This study is one of very few studies that established adaptation measures practiced by smallholder farmers to include mulching, planting early maturing varieties of crops, early harvesting of matured crops, etc. Efforts are needed by the stakeholders such as government at all levels to cushion the effects of climate change.
