Knowledge Management Success Factors – Proposal of an Empirical Research

It is widely accepted that knowledge management is a critical success factor for enterprises. Not yet known sufficiently are the factors, which influence the success of knowledge management in order to measure the effectiveness of knowledge management. This paper sets out a quantitative study to investigate these factors. Firstly, an overview of empirical work undertaken and the potential success factors is given. After this, the methodology of the study is described. Thereby the basics of structure equation modelling (SEM) are shown. The difference between structure and measurement model is depicted and different validity measures are described. Also two common and possible methods to evaluate a SEM, the co-variance analysis and the variance analysis are displayed. Thirdly a specific model is presented to use SEM in the context of knowledge management success. The model is based on the theory of planned behaviour and is adapted to the context of knowledge management success. Thereby knowledge management success is seen on an individual level, which means that successful knowledge management leads to a satisfying knowledge supply of the organisation member. Finally limitations of the work are discussed.
PROFILE OF ULCERATIVE COLITIS IN SOUTH INDIAN REGION: KARAIKAL

The increasing incidence of ulcerative colitis has been reported from western countries and other parts of the world. Even in India this disease is diagnosed to be more common. Though, there is need to study the disease course and its complications from our country. This study was performed to determine the prevalence of ulcerative colitis and to establish the spectrum of disease in India. A total of fifty patients with ulcerative colitis on follow-up in surgery out-patient department were enrolled in this study. The course and severity of the disease and response to the treatment was monitored in all patients prospectively. The response to the treatment was assessed as complete remission, partial remission, and relapse. Out of 74 registered patients, 50 patients (34 male and 16 female) were on regular follow up. During the follow up, 3 patients (2 male and 1 female) had more than 2 relapses per year. 35 patients remained in remission for more than 2 years. Five patients with ulcerative colitis had ileocolonic granulomas and two of these had gastric granulomas. UC is challenging clinical entity requires early diagnosis and therapy to avoid severity of the disease.
Social and Emotional Competencies and Science Performance in the USA: Evidence from PISA 2015

This paper asks whether students with different socioemotional learning (SEL) profiles perform differently in science. Using latent class analysis, we found three distinct groups of students: a majority of students who are relatively unmotivated and isolated, a sizeable group of students who are strong co-operators, and a relatively small group of students who are highly motivated and enjoy science, but do not value cooperation. After controlling for student and family covariates, as well as classroom, teaching and school leadership and institutional variables, the highly motivated, individualist group substantially outperformed the isolated group, with the co-operator group having intermediate performance. These SEL related differences in science performance were large, larger than performance differences associated with socioeconomic variables.

Quintic Pythagorean-Hodograph Curves Based Trajectory Planning for Delta Robot with a Prescribed Geometrical Constraint

A new trajectory planning approach on the basis of the quintic Pythagorean–Hodograph (PH) curve is presented and applied to Delta robot for implementing pick-and-place operation (PPO). To satisfy a prescribed geometrical constraint, which indicates the distance between the transition segment curve and right angle of PPO trajectory is no greater than a prescribed value, the quintic PH curve is used to produce a connection segment path for collision avoidance. The relationship between the PH curve and constraint is analyzed, based on which PH curve is calculated simply. Afterwards, the trajectory is planned in different phases with different motion laws, i.e. polynomial motion laws and PH curve parameter-dependent motion laws, to obtain a smooth performance both in Cartesian and joint space. The relationship between the PH curve and constraint is also used to improve the efficiency of calculation, and the trajectory symmetry is used to reduce calculation time by direct symmetric transformation. Thus, real-time performance is improved. The results of simulations and experiments indicate that the approach in this paper can provide smooth motion and meet the real-time requirement under the prescribed geometrical constraint.
Elucidation of a Role for the Aqueous Extract of Borage in Mammary Gland Growth and Development

INTRODUCTION: Borage Officinalis , in folk medicine , is used as a mucilaginous agent , an anti inflammatory agent , an astringent and an adrenal tonic and gland balancer agent (1,2) . It was also used as a galactagogue for lactating women (1) and it is also used for treatment of the disorders of the immune system ( 3 ) . Today the interest of induced lactation stems from a desire of some adopting mothers to nurse the adopted child ( 4, 5,6) . Moreover , lactation has been induced for scientific and commercial purposes in non-parturient animals (7).
Distributed Spatial Query Processing over MPI

Communication between multiple database nodes in Distributed Spatial Database Systems (DSDB) must be as efficient as possible. This requires a message passing paradigm fit to achieve this. In this way, we have tried to apply MPI standards to implement DSDB kernel. In this work we present a useful result of this attempt that confirms the feasibility and suitability of MPI standards used on the implementation of DSDB kernel. We present the implementation, using MPI standards, of an efficient solution to distributed processing of the intersect spatial join operation, which combines two large spatial data sets that are located on two distinct nodes of a DSDB. This operator is considered a core operator of any DSDB.
SOCIO-ECONOMIC DETERMINANTS OF SUGARCANE PRODUCTION AMONG SMALL SCALE FARMERS IN NYANDO SUGARBELT OF KENYA

Dr. Obange Nelson (PhD) Depatment of Economics, Maseno University, Kenya Sugar industry in Kenya supports livelihood of 25% of the population both directly and indirectly. The industry accounts for about 15% of Agricultural Gross Domestic Product and is a major employer for most households in Western Kenya. Sugarcane outputs in Kenya have been on the decline from a modest 73 tons to 55 tons per hectare between the years 2009 and 2014. This decline has attracted researchers to this area of study; however, most studies have mainly focused on agricultural determinants without regard to the socio and economic determinants of cane production. This study therefore sought to establish socio-economic determinants of Sugarcane production among small scale farmers in Nyando Sugar Belt. The study was anchored on Production Theory and a total of 375 cane farmers responded to the questionnaires used to collect primary data. Secondary data were from farmers’ records. Reliability of the research instruments were ascertained through test-retest method. Multiple regression was used to ascertain the direction and magnitude of influences of the study variables on cane output. The study revealed that variable input costs (land preparation β=0.455 at p-value=0.000, fertilizer application cost β =0.168 at p-value=0.000, weeding and weed control cost β=0.398 at p-value=0.000 and seed cane and planting cost β=0.479 at p-value=0.000) had significant positive effect on cane output. Gender was also found to have a significant effect on cane output at β=0.093 and p-value=0.010. It is recommended that more investments be made on land preparation, fertilizer application, weeding and weed control and seed cane and planting to improve cane output. The study also recommends for interventions targeting female headed households to enhance cane output. Socio-economic, Sugarcane,
CEO OVERCONFIDENCE, BUSINESS STRATEGY AND EARNINGS MANAGEMENT

This study aims to examine whether CEO overconfidence influences the relationship of business strategy and market competition to real earnings management. The sample used in this study is manufacturing companies listed on the Indonesia Stock Exchange in the period 2014-2016. The results of this study indicate that the cost leadership strategy has a positive effect on real earnings management while the differentiation strategy has a negative effect on real earnings management. The use of cost leadership strategies and high market competition will improve real earnings management but do not affect the differentiation strategy. Whereas CEO overconfidence strengthens the relationship between strategy differentiation and real earnings management. However, the results of this study also show that the interaction between business strategy, market competition and CEO overconfidence has no influence on real earnings
Occurrence of hepatitis 'B' and 'C' amongst patients on antiretroviral drug therapy (ART) in a treatment centre in Calabar, Nigeria

The occurrence of hepatitis ‘B’ and ‘C’ virus amongst patients on antiretroviral drug therapy (ART) was studied. Two hundred (200) human immunodeficiency virus (HIV) positive subjects on ART and 100 apparently healthy HIV negative subjects (control) were recruited for the study. The subjects aged 1 to 75 years were screened for hepatitis B and C viral antibodies using hepatitis B and C test strips manufactured by ACON Laboratories. Questionnaire were also administered. CD4 counts of the subjects were determined using CyFlow Counter manufactured by GEM Laboratories, Germany. Fourteen (7%) of the subjects were positive for hepatitis B virus (HBV) infection, 6 (3%) for hepatitis C virus (HCV) and 2 (1%) for mixed infections. In the control group, a prevalence of 6 (6%) was recorded for HBV, 4 (4%) for HCV and none for mixed infections. Among the test group, subjects in age group 51 to 60 years had the highest prevalence rate for HBV (25%), 31 to 40 years for both HCV (7.3%) and mixed infection (3.6%). There was no statistically significant difference in infection according to age P=0.475. Males had a higher prevalence rate (9.1%) than the females (5.4%) for HBV, but there was no statistically significant difference in HBV infections according to gender P=0.404. In HCV infection, males had a higher prevalence rate (5.7%) than females (0.9%), but there was no statistically significant difference in HCV infection according to gender P=0.089. Subjects with CD4 counts in the range of 1401 to 1600 had the highest infection rate (50%) for HBV and 201 to 400 for HCV (7.7%) and mixed infection (5.1%). This work has shown that HBV and HCV are common among patients on ART and the need for routine screening of this category of patients in order to aid in the effective management of co-infections.

Working Papers on Innovation and Space

In the literature there is a controversy about the relevance of the spatial dimension in innovation collaboration. We examine the link between the spatial composition of group members and group characteristics which are important for performing innovation projects. To this end, we introduce a social-psychological approach to the field of economic geography. The empirical part is a longitudinal study of 49 interorganisational innovation groups in Germany. We find that the share of regional partners is rather stable after a funded formation stage. Hence, policy measures aiming at inter-regional collaboration have to be employed at an early stage of group development.
www.econstor.eu Opinion Dynamics and Wisdom under Conformity∗

We study a dynamic model of opinion formation in social networks where individuals repeatedly engage in discussion (similarly to the DeGroot model). As our main contribution, we allow agents to misrepresent their opinion in a conforming or counter-conforming way. Conformity of all agents is a sufficient condition for convergence of opinions. Studying these long-run opinions in detail, we show that an agent’s social influence on the group opinion is increasing in network centrality and decreasing in the degree of conformity. Moreover, assuming that the initial opinion is a noisy signal about some true state of the world, we study how conformity affects the efficiency of information aggregation or the “wisdom” of the society. We provide the optimal distribution of conformity levels in the society and show which agents should be more conforming in order to increase wisdom.
NEXUS BETWEEN USERS’ PERCEIVED RISK,PERCEIVED LEGISLATION ANDE-COMMERCE ACCEPTANCE: IMPLICATIONSFOR E-COMMERCE ADOPTION INSOUTHWEST NIGERIA

This paper investigates the impact of perceived risk and perceived legislation on ecommerce acceptance. Questionnaire was used to collect data from 666 come-toclaim customers of top 4 e-Commerce organizations. Hypotheses were tested using Hierarchical Regression Analysis. The results revealed that perceived risk and legislation have significant effects on e-Commerce acceptance. The study expanded the application of theory discussed in this study which allow for contribution to the theorizing of e-commerce adoption by substituting behavioural variables with internet security variables to the already established UTAUT model. The paper recommends that government should provide a regulatory framework to drive the e-commerce sector.
A clinical study on seizure disorder in intellectually disabled patients in Barak Valley, North-Eastern India

Background: Intellectual disability (ID) is a state of developmental deficit, beginning in childhood which results in significant limitation of intellect or cognition and poor adaption to the demands of everyday life. The relationship between seizure disorders and ID, and their socio-demographic correlations is a current topic of research to implement proper psychosocial interventions and to eliminate the preventable causes of ID as well as seizure disorder. Aims: To find out the prevalence of seizure disorders and their types in the intellectually disabled patients, and find out their socio-demographic correlations. Materials and methods: A cross-sectional study sample comprising of 100 intellectually disabled patients of Silchar Medical College and Hospital was taken, and the study was conducted after obtaining institutional ethical committee approval and permission from the college. Diagnostic and Statistical Manual of Mental Disorders, fifth edition (DSM-5) criteria were used for diagnosing ID. A standardised proforma describing socio-demographic variables, Malin’s Intelligence Scale for Indian Children (MISIC) for children in age group six to 17 years, Wechsler Adult Intelligence Scale, third edition for subjects above 18 years, and the Vineland Social Maturity Scale were applied to diagnose and classify ID. International League Against Epilepsy guidelines were used to classify seizure disorder. Results: Prevalence of seizure disorder was found to be 22% among the intellectually disabled population in our sample. A significant association was found between the severity of ID and increased incidence of seizure disorder (p=0.0045). Seizure disorder was more prevalent in the low intelligence quotient (IQ) group (p=0.0067). Generalised tonic clonic seizure (GTCS) was the commonest among the types of seizure disorder (n=11, 50%). Among the GTCS cases, eight out of 11 (72.7%) were from severe/profound ID group and from an IQ range of one to 35. Conclusion: A strong association was observed in our study between seizure disorder and poor IQ group, and with increasing severity of ID (severe and profound ID). As expected, GTCS variety was found to be more strongly associated out of all types of seizures with the groups of poor IQ and severe forms of ID. In addition, we have also observed a significant association between seizure disorder, ID, and few important socio-demographic variables.
The role of chemotherapy in hormone receptor positive advanced breast cancer

En el cáncer de mama, los conceptos de heterogeneidad tumoral y tratamiento individualizado son reconocidos y de cierta forma ya validados. Pacientes con cáncer de mama avanzado con receptores hormonales positivos y con enfermedad lentamente progresiva son generalmente seleccionadas para tratamiento hormonal. Entretanto en casos donde hay comprometimiento visceral existe controversia con relación a la mejor estrategia o secuencia mas adecuada de quimioterapia y agentes hormonales. Para algunos, la percepción es que la quimioterapia, mientras más tóxica es de cierta forma mas eficaz que el tratamiento hormonal y por este motivo debería ser considerada como la opción preferencial de tratamiento. Mientras esto puede ser aceptable en casos de crisis visceral con enfermedad rápidamente progresiva y sintomática, evidencias definitivas que soporten la superioridad de la quimioterapia sobre tratamiento hormonal en la mayor parte de los casos con metástasis viscerales. En esta revisión, examinamos parte de la evidencia que explora el uso de la quimioterapia en el cáncer de mama receptor hormonal positivo avanzado. Todavía, discutimos informaciones sobre el uso de hormonoterapia en la misma situación sosteniendo que mismo en presencia de metástasis viscerales, por lo menos en casos T ABSTRACT
Evolution of the Anisotropy Over a Flat plate With Suction

Laser Doppler Velocity measurements are carried out in a turbulent boundary layer subjected to a concentrated wall suction (through a porous strip). The measurements are taken over a longitudinal distance of nine times the incoming boundary layer thickness behind the suction strip. The results indicate that the state of the perturbed boundary layer departs from that of the pseudo-equilibrium of the unperturbed layer. It is found that suction alters the redistribution of the turbulent kinetic energy between its components. Relative to the no suction case, the longitudinal Reynolds stress contributes more to k than the other two normal Reynolds stresses; in the outer region, its contribution is reduced. The alteration of the energy transfer between the turbulent kinetic energy components reflects structural changes in the boundary layer. This is observed in the anisotropy of the Reynolds stresses, which depart from the non disturbed boundary layer. With suction, the anisotropy level in the near wall region appears to be stronger than that of the undis turbed layer. It is argued that the mean shear induced by suction on the flow is responsible for the alteration of the anisotropy. The variation of the anisotropy of the layer will make the development of a turbulence model quite difficult for the flow behind suction. In that respect, a turbulence model will reproduce well the effects of the suction on the boundary layer, if the model captures the effect of suction on the anisotropy of the Reynolds stresses.
The Effect of Compressing High School Education on University Performance

A recent education reform in Germany reduced the duration of academic high school education by one year but left the curriculum, and total class time unchanged. We use a unique data set of university students to investigate the effects of this reduction in years of schooling on academic achievements at the tertiary level. By exploiting variation in the implementation of the reform across school types over time, we isolate the reform effect from cohort, state, and school type effects. Our results suggest that the reform lowers the opportunity costs of schooling and facilitates an earlier labor market entry as we find no detrimental effects while students are one year younger on average.

Antibacterial effects and microbial quality of commonly consumed herbs in Dubai, United Arab Emirates

Herbal plants are traditionally known to exhibit antimicrobial properties and used in several countries as an alternative to modern pharmaceutical drugs. This study investigated the antibacterial properties and microbial quality of common herbs used in the United Arab Emirates (UAE). In total, 20 herb samples of parsley (Petroselinum crispum), basil (Ocimum basilicum), sage (Salvia officinalis), mint (Mentha spicata), and thyme (Thymus vulgaris) were randomly collected and analysed for the total aerobic bacteria count, yeasts and molds, Escherichia coli, Staphylococcus aureus, Salmonella and Pseudomonas aeruginosa by standard plate counting method using selective and differential culture media. Antibacterial effects of herbs on E.coli, S. aureus, Salmonella and P. aeruginosa were tested by disk diffusion method. The microbial analysis of herbs revealed that 50% of herb samples exceeded the world health organization (WHO) limit for the total aerobic bacteria count, and 75% exceeded the permissible limit for total molds and yeast count. 75% of herb samples were found contaminated with Escherichia coli and Salmonella spp, 65% with Shigella, and 10% exceeded the WHO permissible limit for Pseudomonas aeruginosa. However, all herb samples were found to be within the WHO acceptable limit for Staphylococcus aureus. All herbal extracts exhibited some form of antibacterial activity against E. coli, S. aureus, Salmonella and P. aeruginosa except for parsley, which had no inhibitory effect on S. aureus. However, the results of microbial quality suggest that most of the analysed herbs had unsafe microbial contamination that exceeded the World Health Organization permissible limits. Therefore, strict measures to reduce the risk of microbial contamination by applying Hazard Analysis and Critical Control Point (HACCP) need to be implemented on local and imported herbs prior to consumption.
