Persistence and Acuteness of Research Gaps in Entrepreneurship Education: A Systematic Content Analysis of Previous Reviews (1987-2017)

This paper provides insight into the persistence and acuteness of subject-related and methodological research gaps in the field of entrepreneurship education through a systematic content analysis of all review papers from 1987 until 2017 (N=16). The goal is to create an overview of study subjects and methods for future studies that would advance the field. Content analysis and coding are executed by a single coder in three consecutive rounds to increase reliability. The subcategories for subjects are ‘objectives’, ‘impact measurement’, ‘audience’, ‘content (curriculum and pedagogy)’, ‘instructors’ and ‘institutional context’. The subcategories for methods are ‘type of research methods’, ‘quality of research methods’, ‘(inter)disciplinary approach’ and ‘geographical setting’. The paper outlines the value of addressing these gaps and proposes future studies that are interdisciplinary, context-sensitive and comparative with high quality, mixed method study designs. How long it will take to close these gaps depends on the combined support of researchers, grant-awarding institutions and editors.
World towards Advance Web Mining: A Review

With the advent of the World Wide Web and the emergence of e-commerce applications and social networks, organizations across the Web generate a large amount of data day-by-day. The abundant unstructured or semi-structured information on the Web leads a great challenge for both the users, who are seeking for effectively valuable information and for the business people, who needs to provide personalized service to the individual consumers, buried in the billions of web pages. To overcome these problems, data mining techniques must be applied on the Web. In this article, an attempt has been made to review the various web mining techniques to discover fruitful patterns from the Web, in detail. New concepts are also included in broad-sense for Optimal Web Mining. This paper also discusses the state of the art and survey on Web Mining that is used in knowledge discovery over the Web.
Isolation of Stigmasterol from Aerial Plant Part of Spillanthes Acmella Murr

Pulverized aerial plant material (300 g) of Spillanthes acmella was exchaustively extracted with methanol and concentrated in vacuo using rotary evaporator at 40oC.the extract was later subjected to solvent partitioning to yield the following extracts petroleum ether, chloroform, Ethyl acetate and methanol. The petroleum ether crude extract was subjected to Vacuum Liquid Chromatographic (VLC) technique to yield various fractions which were combined based on their thin layer chromatography analysis to give SPEC. This was further purified by the Preparatory Thin Layer Chromatography (PTLC) to give SPEC-1.The structure of the isolated compound was established by 1D and 2D NMR spectroscopic analysis and by direct comparison of the data obtained with those reported in literature to be Stigmasterol.
Impact of Organisational and Psychological Factors on the Job Performance of Personnel in Private University Libraries in South-South Nigeria

The study examined organisational and psychological factors as correlates of job performance of personnel in private university libraries. Descriptive research design was adopted in the study. The total population of the study comprised of 83 respondents in the 8 private universities in South-South Nigeria. Since the population was small, total enumeration sampling technique was employed. The instrument adopted for the collection of data was the questionnaire. The questionnaire was structured based on 4-point Likert scale of Strongly Agree, Agree, Disagree and Strongly Disagree. Of the 83 copies of questionnaires administered, 73 (94.0%) were found valid for analysis. The data collected were used to test the eight null hypotheses at 0.05 level of significance. The results of the study showed that organisational factors (organisational culture and organisational commitment) are stronger corrolates of job performance among personnel in private university libraries in South-South Nigeria than psychological factors (work motivation and self-esteem).
PRELIMINARY STUDY FOR THE DEVELOPMENT OF UNCERTAINTY AVOIDANCE INSTRUMENT IN TURKEY

Hofstede’s five cross-cultural dimensions have been broadly studied in the literature. One of these dimensions, uncertainty avoidance (UA) is defined as the extent to which the members of a culture feel threatened by uncertain or unknown situations. This is a preliminary study for the development of a new UA scale for Turkish culture. First, an item pool was generated by a qualitative analysis that included collecting suggestions from a group of respondents and by using items from pre-existing scales. Then, an advisory board assessed the similarity of the generated items and deleted those items that meant the same thing with different words. After the experts’ evaluation process, the remaining 61-items were distributed to 378 participants, and the data was analyzed by conducting exploratory factor analysis. The results revealed 35 items with six factor solutions – (1) Openness to Innovation and Change, (2) Authority of Rules, (3) Information Seeking and Controlling, (4) Anxiety, (5) Definiteness and (6) Strictness of Rules. Finally each factor was discussed in terms of current literature and characteristics of Turkish culture.
Identifying the primitive path mesh in entangled polymer liquids

Similar to entangled ropes, polymer chains cannot slide through each other. These topological constraints, the so-called entanglements, dominate the vis- coelastic behavior of high-molecular-weight polymeric liquids. Tube models of polymer dynamics and rheology are based on the idea that entanglements confine a chain to small fluctuations around a primitive path which follows the coarse-grained chain contour. To establish the microscopic foundation for these highly successful phenom- enological models, we have recently introduced a method for identifying the primitive path mesh that characterizes the microscopic topological state of computer-generated conformations of long-chain polymer melts and solutions. Here we give a more detailed account of the algorithm and discuss several key aspects of the analysis that are pertinent for its successful use in analyzing the topology of the polymer config- urations. We also present a slight modification of the algorithm that preserves the previously neglected self-entanglements and allows us to distinguish between local self-knots and entanglements between distant sections of the same chain. Our results indicate that the latter make a negligible contribution to the tube and that the con- tour length between local self-knots, Nlk is significantly larger than the entanglement length Ne. � 2005 Wiley Periodicals, Inc.

Millennial total sea-level commitments projected with the Earth system model of intermediate complexity LOVECLIM

Sea-level is expected to rise for a long time to come, even after stabilization of human-induced climatic warming. Here we use simulations with the Earth system model of intermediate complexity LOVECLIM to project sea-level changes over the third millennium forced with atmospheric greenhouse gas concentrations that stabilize by either 2000 or 2100 AD. The model includes 3D thermomechanical models of the Greenland and Antarctic ice sheets coupled to an atmosphere and an ocean model, a global glacier melt algorithm to account for the response of mountain glaciers and ice caps, and a procedure for assessing oceanic thermal expansion from oceanic heat uptake. Four climate change scenarios are considered to determine sea-level commitments. These assume a 21st century increase in greenhouse gases according to SRES scenarios B1, A1B and A2 with a stabilization of the atmospheric composition after the year 2100. One additional scenario assumes 1000 years of constant atmospheric composition from the year 2000 onwards. For our preferred model version, we find an already committed total sea-level rise of 1.1 m by 3000 AD. In experiments with greenhouse gas concentration stabilization at 2100 AD, the total sea-level rise ranges between 2.1 m (B1), 4.1 m (A1B) and 6.8 m (A2). In all scenarios, more than half of this amount arises from the Greenland ice sheet, thermal expansion is the second largest contributor, and the contribution of glaciers and ice caps is small as it is limited by the available ice volume of maximally 25 cm of sea-level equivalent. Additionally, we analysed the sensitivity of the sea-level contributions from an ensemble of nine different model versions that cover a large range of climate sensitivity realized by model parameter variations of the atmosphere–ocean model. Selected temperature indices are found to be good predictors for sea-level contributions from the different components of land ice and oceanic thermal expansion after 1000 years.
Predictors of satisfaction with health care: a primary healthcare-based study

Objective The main aim of this study was to examine the overall satisfaction with health care among a multi-ethnic primary healthcare practice population. The second aim was to explore the relations between satisfaction/dissatisfaction and sociodemographic characteristics, health status, healthcare utilisation and medicine use in Jordbro,Haninge,Sweden. Method The study included 1055 out of 1442 consecutive adult patients visiting a Swedish healthcare centre. The relationship between satisfaction and socio-demographic characteristics, perceived health, chronic disease, complaint symptom, consultations with the general practitioner (GP) and healthcare need was assessed using final logistic regressionanalysis.Results Age, perceived health and complaint symptoms were related to patient satisfaction with health care in the univariate analysis. However, only age and healthcare need remained significantly and independently related to patient satisfaction in thelogistic regression analyses when the impact of all confounders was taken into account. Age under 65 years and healthcare need were the strongest predictors of dissatisfaction with health care. Poor perceived health and low numbers of consultationswith the GP were related to reporting that healthcare need was not met.Conclusion Age and healthcare need were significantly and independently related to patient satisfaction in the logistic regression analysis adjusted for all confounders. Poor perceived health was related to dissatisfaction and unmet healthcare need in the univariate analyses. Maintaining a continuous relationship with patients with poor perceived health is essential, and efforts should be made to improve the quality of care for these patients.
Standardization of organic module for sustainable productionof fenugreek (Trigonella foenum graecum L.)

A field experiment on the standardization of organic module for production of fenugreek (Trigonella foenum graecum L.) was conducted during rabi season of 2009-10 to 2012-13 (four years). The experiment was laid out in Factorial Randomized Block Design (RBD) consisting of three organic modules (M1, M2 and M3) and two fenugreek varieties (AFg-1 and RMt-305) with four replications. Findings of present study showed significant differences among the performance of different organic modules tested for two fenugreek varieties. Organic module-1 (M1)comprising of soil application of vermi-compost @5 t/ha+ foliar spray of 5% garlic extract @ 2.0 kg/ha + 2% neem oil @ 5 litre/ha+ soil application of neem cake @150 kg/ha and Trichoderma @ 2.5 kg/ha, seed treatment with Rhizobium @100 ml/kg seed, PSB @ 100 ml/kg seed and Trichoderma @10 g/kg seed exhibited earliest seed germination and maximum plant height (5.78, 19.69, 43.39 and 50.97 cm) at 30, 60, 90 DAS and at harvest, respectively with maximum number of branches (6.76/ plant), number of pods (42/ plant), number of seeds (16.01/ pod), highest grain yield (1515.21 kg/ha), gross return (100004) and net returns (66741) in fenugreek crop. Similarly significant differences were recorded in the performance of fenugreek varieties under different organic modules and the highest plant height, maximum number of branches and pods per plant, highest number of seeds per pod with maximum grain yield (1568.36 kg/ha), gross returns (103512), net returns (71399) with higher B:C ratio (2.22) were recorded in fenugreek variety AFg-1 than variety RMt-305. Cultivation of fenugreek variety AFg-1 with the application of Module-1 exhibited maximum values for all the growth parameters, yield attributing characters, maximum grain yield, net returns with improvement in soil organic carbon % (OC) and soil fertility (available N, P and K) after 4 crop cycles. Hence, variety AFg-1 is recommended to grow organically with the application of Module-1 (M1) under semi-arid environmental conditions.
Pre-Service Teachers and Search Engines: Prior Knowledge and Instructional Implications.

There is a wealth of information available on the World Wide Web that can assist pre-service teachers in their course studies. Yet observation of students in a technology integration class indicated that students were not able to find resources efficiently or reliably. The purpose of this study was to establish a baseline of what undergraduate, pre-service teachers know about search engines and searching the Web prior to beginning a course on integrating technology into the classroom. A total of 355 undergraduate, pre-service teachers over three semesters participated in the study. The results indicate low declarative, syntactic and semantic knowledge. Implications for course and program revisions based on the results are addressed. Academic programs are continuously under evaluation and revision. Whether through a formal process from an outside agency, or the individual reflections of an instructor, these reviews seek to determine the effectiveness and value of a specific course or program in terms of the validity of objectives, relevancy and sequence of content, relation between assumed prior knowledge and current course content, and achievement of specific goals. In an internal review of a technology integration course at a southeastern university, the researchers found that faculty in the college of education assumed students at the university knew how to use the Internet as a source of information to support their academic studies. Yet the researchers observed many students had difficulty locating information relevant to their courses and assignments. The researchers also observed students spent a great deal of time on unsuccessful searchers; few students were able to locate relevant resources quickly. The purpose of this study was to establish a baseline of what undergraduate, pre-service teachers know about search engines and search strategies. The results would then be used to determine if any changes in the curriculum were warranted.
A flow-through analysis of the US lodging industry during the great recession

Purpose – The objective of this exploratory study is to investigate the “flow-through” or relationship between top-line measures of hotel operating performance (occupancy, average daily rate and revenue per available room) and bottom-line measures of profitability (gross operating profit and net operating income), before and during the recent great recession. Design/methodology/approach – This study uses data provided by PKF Hospitality Research for the period from 2007-2009. A total of 714 hotels were analyzed and various top-line and bottom-line profitability changes were computed using both absolute levels and percentages. Multiple regression analysis was used to examine the relationship between top and bottom line measures, and to derive flow-through ratios. Findings – The results show that average daily rate (ADR) and occupancy are significantly and positively related to gross operating profit per available room (GOPPAR) and net operating income per available room (NOIPAR). The evidence indicates tha.
Karyotypic studies of four species of the blackfly , Simulium ( Diptera : Simuliidae )

Karyotypic studies were carried out on the mitotic chromosomes from the supraoesophageal ganglia of four species of the blackfly, Simulium. The four species were Simulium alcocki Pomeroy, Simulium damnosum Theobald sensu lacto and two yet unidentified species of Simulium herein referred to as US 1 (unidentified species 1) and US 2 (unidentified species 2). A diploid number (2n) of 6 was obtained for all the species of blackfly studied. A modified method for preparing mitotic chromosomes from the supraoesophageal ganglia was developed. This involved placing the fixed paired supraoesophageal ganglia in 2.5% hydrochloric acid for 1 to 2 s and staining in FLP orcein for 10 to 15 min. Idiograms were constructed for all the four species studied. Standard methods were adopted in the classification and nomenclature used in describing the chromosomes of the four species of blackfly in the investigation. No structural aberrations were observed in any of the species studied.
Dual Class Firms and Debt Issuance

We examine the impact of dual class share structures on the parameters of debt issuance. We find that, as compared to single class firms, the debt in dual class firms is associated more use of covenants especially performance based covenants, and is more likely to be secured. In addition, the impact of dual class share structure differs based on the severity of the agency costs of debt. We find that many of these issuance parameters are differently affected for large, profitable and low leverage firms (which face lower agency costs of debt) as opposed to small, less profitable and highly levered firms. These results are robust when we control the endogeneity of ownership structure and simultaneous changes in these issuance parameters. These results suggest that dual class share structures exacerbate the conflicts between controlling shareholders and lenders. However, the link between dual class share structures and debt issuance is not as clear for other issuance parameters such as the maturity and interest cost of debt.
Calculation of eigensolution derivatives for nonviscously damped systems using nelson's method

A method to calculate the derivatives of the eigenvalues and eigenvectors of multiple-degree-of-freedom damped linear dynamic systems with respect to arbitrary design parameters is presented. In contrast to the traditional viscous damping model, a more general nonviscous damping model is considered. The nonviscous damping model is such that the damping forces depend on the past history of velocities via convolution integrals over given kernel functions. Because of the general nature of the damping, eigensolutions are generally complex valued, and eigenvectors do not satisfy the classical orthogonality relationship. The proposed method to calculate the eigenvector derivative depends only on the eigenvector concerned. Numerical examples are provided to illustrate the derived results. Nomenclature c j = constant associated with the derivative of u j D(s) = dynamic stiffness matrix d j = constant associated with the derivative of v j G(s) = Laplace transform of G(t) G(t) = nonviscous damping matrix K = stiffness matrix L[ ] = Laplace transform of [ ] M = mass matrix m = total number of eigenvectors N = number of degrees of freedom of the system n = number of relaxation parameters p = design parameter rank () = rank of a matrix s = Laplace domain parameter u j = jth eigenvector (t) = displacement vector v j = jth adjoint (left) eigenvector x j = vector associated with the derivative of u j yj = vector associated with the derivative of v j θ j = normalization constant for the jth eigenvector λ j = jth eigenvalue μk = relaxation parameters Subscripts () T = matrix transpose () � = derivative with respect to s
Malignant renal tumours seen in the University of Port Harcourt Teaching Hospital, Port Harcourt, Nigeria

Introduction: Malignant renal tumours (MRTs) pose significant morbidity and mortality. In adults, renal cell carcinoma (RCC) constitutes about 90% of these tumours whereas in children, the majority are nephroblastomas. Males are generally more affected than females. Nuclear grade, tumour stage, size and histopathological subtype are prognostic factors. In our environment, patients with MRTs commonly present late. Methods: Clinical and demographic details of patients who had malignant tumours diagnosed on renal biopsy tissue between 2002 and 2013 at the University of Port Harcourt Teaching Hospital, Port Harcourt, Nigeria, were extracted from pathology request forms. Slides were retrieved from the archives and reviewed. The tumours were classified according to WHO and ISUP criteria. Results: Kidney biopsies constituted 0.8% of the biopsy specimens processed within the period; 60% of these were malignant lesions. Half (51%) of the patients with MRTs were males and 81% were children (the majority aged 0–4 years). Among children, the incidence decreased steadily with age. Seventy-three percent were nephroblastomas, exclusively occurring in children. Renal cell carcinoma constituted 19.4%, with papillary carcinoma being the commonest subtype, whereas non-Hodgkin’s lymphoma and rhabdomyosarcoma constituted 6% and 1.5%, respectively. The mean gross weight of the tumour masses was 1.3 kg and the average duration of symptoms prior to presentation was 18.3 months. The majority presented with abdominal masses. Conclusion: Although the renal biopsy rate is generally low in our environment, we found that the most common renal malignancy was nephroblastoma in children. In adults, renal cell carcinoma, mainly of the papillary type, was predominant. Most cases present late.
Arsenic Speciation, Seasonal Transformations, and Co-distribution with Iron in a Mine Waste-Influenced Palustrine Emergent Wetland

Arsenic is commonly associated with mined ores and thus may be detrimental to naturally occurring wetlands that reside in mine waste-impacted regions. Understanding the relationship between Fe and As in both the aqueous and solid phase is critical for assessing the risk As imposes on these sensitive ecosystems. Therefore, in this investigation, Fe (perceived to be a dominant factor in the cycling of As) and As were monitored seasonally in a mine waste-influenced wetland. Iron and As concentrations in the pore waters at the site were highly variable but were at the highest levels during the spring and summer months. Using X-ray absorption near edge structure (XANES) spectroscopy, we confirmed that arsenite, arsenic sulfides, and arsenate species were present in the soil-solids, all of which varied seasonally within the site. Additionally, the reactivity of Fe and As solid phases, as measured by selective sequential extractions, changed seasonally. Iron and As are positively correlated in the sodium acetate.
TIME - Targeted Interdisciplinary Model for Evaluation and Treatment of Neuropsychiatric Symptoms – a cluster randomized controlled trial

Objectives To determine the effectiveness of the Targeted Interdisciplinary Model for Evaluation and Treatment of Neuropsychiatric Symptoms (TIME), for treatment of moderate to severe agitation in people with dementia. Design A single blinded cluster randomised controlled trial. Setting 33 nursing homes (clusters) from 20 municipalities in Norway. Participants 229 patients, 104 patients in 17 nursing homes and 125 patients in 16 nursing homes were randomised to the intervention group and the control group, respectively. Intervention The intervention group received TIME, and the control group received a brief education-only intervention. TIME is an interdisciplinary multicomponent intervention and consists of a comprehensive assessment of the patient with the goal to create, and put into action, a tailored treatment plan. Measurements The primary outcome was the between-group difference in change at the agitation/aggression item of the NPI-NH between baseline and eight weeks. Secondary outcomes were the between-group difference in change at the agitation/aggression between baseline and 12 weeks, in other neuropsychiatric symptoms,
