The effect of managerial entrepreneurship behavior on employee satisfaction: Hospitality managers' dilemma

This study analyses the effect of managerial entrepreneurship behavior on employee satisfaction. For the variables mentioned, the environmental and structural variables in particular, which we suppose have an influence on the satisfaction, are used as moderators in this study. According to the findings acquired, there is a strong and a positive correlation between the managerial entrepreneurship behavior and satisfaction. Also, the entrepreneurial behavior explains 75% of the employee satisfaction due to this behavior. The hierarchical regression analysis, realized according to the model, shows that only the variable of the static-dynamic dimension of the process environment has a quasi moderator effect on the satisfaction due to entrepreneurial behavior between the other moderator-variables. Of the organizational structure variables, the formalization and the centralization degree have a quasi moderator variable effect on the satisfaction of the managerial behavior. Consequently, the findings give us the result that the structural variables in the organization can be controlled, that these variables can be organized by managerial techniques for the benefit of the employees and that the managerial behaviors are very important for the perception and the satisfaction of the employees.
The Role of Innovation in Development

Innovation is often seen as carried out by highly educated labour in R&D intensive companies with strong ties to leading centers of excellence in the scientific world. Seen from this angle innovation is a typical "first world" activity. There is, however, another way to look at innovation that goes significantly beyond this high-tech picture. In this, broader perspective, innovation - the attempt to try out new or improved products, processes or ways to do things - is an aspect of most if not all economic activities. In this sense, innovation may be as relevant in the developing part of the world as elsewhere. Section two discusses the existing theoretical and empirical literature on the subject. An important conclusion is that to be able to exploit technology to their own advantage, developing countries need to develop the necessary capabilities for doing so. The third section of the paper, therefore, discusses ways to identify and measure capabilities at the national level, while section four focuses on recent attempts to survey innovation activity in firms. The final section summarizes the main lessons.
DETERMINANTS OF BUSINESS GROUPS’ PERFORMANCE: EMPIRICAL EVIDENCE FROM PAKISTAN

Business groups have been described as improving the value of the affiliated firms they control, something which is often beyond the capability of standalone firms. The purpose of the current thesis is to increase overall understanding as regards the factors determining the performance and the value of firms affiliated with business groups. The current study employs data from 284 Pakistani listed non-financial firms from 2008–2015. The research has analysed the effect of tangible and intangible resources and interlocking directorates on the performance of individual firms affiliated with business groups. In order to test the hypotheses, two dependent variables are used, namely accounting (ROA) and stock market (Tobin’s q) measures of performance. Specifically, this thesis is composed of three empirical studies: the first probes and compares the performance measures of group member and standalone firms; the second part investigates the effect of tangible and intangible resources on financial performance, with the value of firms connected with business groups; and finally, the last section explores the way in which interlocking directorates influence the performance and control management of group-affiliated firms. The findings of the first part of Chapter 5 report a strong and robust evidence of superior performance of group-member firms. It is documented that business group memberships have statistically significant positive effects on financial performance and the value of firms. Therefore, group membership seems to be a determining factor of performance between group-member firms and standalone firms. In addition, size and sales growth has an increasing effect on the performance of firms. The findings suggest that business groups in Pakistan are efficient economic actors that substitute for missing external capital markets and weak institutions by reducing transaction Costs and information asymmetry between the firm and market. Applying the framework of tangible and intangible resources by focusing on panel and crosssectional data of publicly listed Pakistani firms, in the second part of Chapter 5, a positive
HPTLC ASSAY OF THYMOQUINONE IN BLACK SEED AND BLACK SEED OIL (NIGELLA SATIVA LINN) AND IDENTIFICATION OF THYMOQUINONE CONVERSION WITH UV-VIS

A reliable and simplified quantitative high performance thin-layer chromatography (HPTLC) method for the determination of the bioactive constituent of the commercially available black seed and black seed oil using a scanning densitometer is described. The identification of thymoquinone spot obtained from 80% aq. MeOH extract of the seed is confirmed by Nuclear Magnetic Spectroscopy (NMR). The solvent system consisted of hexane and dichloromethane (1:1) were used and all the spot visualised and quantitated at 254 nm. The thymoquinone content of freshly pressed black seed oil was 1.3%, while that of the seed was 1%. Furthermore UV-Vis measurement is significantly used for swift relative comparison of thymoquinone levels in black seed oils and to follow the transformation of thymoquinone when the oil is exposed to sunlight. Keywords: Nigella sativa; black seed; black cumin; black cumin oil; thymoquinone.
Using the Durbin-Watson Ratio to Detect a Spurious Regressions: Can We Make a Rule of Thumb?

Recent advances in time series analysis related to unit root and cointegration make us nervous about spurious regressions. Spurious regression refers to the case where some statistically significant coefficients are often obtained in regression analysis when the dependent and independent variables are mutually independent random walks. High R-squared and significant t-values might mislead us to nonsense regressions. In this paper, we focus on the Durbin-Watson (DW) ratio and investigate whether it is helpful in detecting spurious regressions in empirical analyses or not. This statistic has a useful property to discriminate cointegrating relationships and spurious regression. In the case of a spurious regression, the DW ratio converges to zero, so it can be utilized for testing the hypothesis of a cointegrating relationship. However, there are several types of nonsense regressions. In some cases, the asymptotic distributions of the t-value, DW ratio or other statistics have been studied, but how the statistics might be utilized in testing or detecting a nonsense regression has not been investigated. In order to investigate if a traditional diagnostic testing process using t-values and the DW ratio works, I conduct a Monte Carlo simulation. The results show that the traditional diagnostic testing process when we check t-values and the DW ratio in the first regression and then proceed to cope with the serial correlation in disturbances works, and we can detect nonsense regressions when the spurious effect arising from non-stochastic part is removed. If the spurious effect is not removed, we have a statistically significant coefficient even in the second regression (Cochrane=Orcutt method). This result suggests that we should pay attention to whether the sources of spurious effects can be removed in the second regression or not. In other words, to apply a proper model to data is one of the most important step in detecting a spurious regression.
A Wide-Band, Polarization-Insensitive and Wide-Angle Terahertz Metamaterial Absorber

In this paper, a wide-band, polarization-insensitive, wideangle terahertz metamaterial absorber is presented. Simulated results show that the absorber can achieve polarization-insensitive, wide-angle absorptions in a wide band from 4.15 to 4.85 THz. The retrieved impedance shows that the impedance of the absorber could be tuned, in the absorption band, to match approximatively that of free space on one side and to mismatch on the other side, rendering both the reflectance and transmission minimal and thus the corresponding absorbance maximal. The simulated absorbances under three different Received 1 July 2010, Accepted 15 September 2010, Scheduled 23 September 2010 Corresponding author: C. Gu (guchao123abc@139.com).
Análisis y percepción por parte del alumnado del requisito lingüístico en el acceso al Máster de Formación del Profesorado de Educación Secundaria

espanolEl aprendizaje de un segundo idioma ha sido historicamente un aspecto dificil de abordar en Espana. Como se puede observar en recientes estudios, la capacidad de nuestra poblacion para mantener una conversacion en un segundo idioma esta en entredicho. El nuevo procedimiento de acceso al Master de Formacion del Profesorado de Educacion Secundaria, para el que es necesaria la acreditacion de una competencia comunicativa a nivel intermedio (B1) en una segunda lengua, ha puesto de manifiesto esta carencia. Con este trabajo pretendemos analizar la percepcion de estos alumnos en referencia este requisito linguistico y como han podido cumplirlo. Mediante un cuestionario validado y disenado ad hoc, hemos extraido conclusiones reveladoras acerca de estos dos aspectos. Nos ha parecido interesante estudiar el papel del centro de idiomas de educacion superior como herramienta que lleve a cabo la politica linguistica de las universidades. En definitiva, hemos podido obtener una imagen global que nos permita prever como el proceso de acreditacion se acoplara a los nuevos grados EnglishLearning a second language has always been a problem for Spanish students. As it can be drawn from recent studies, the ability to have a conversation in a second language is not common. The new way to access the Master de Formacion del Profesorado de Educacion Secundaria, for which it is compulsory to prove a CEF B1 level in a second language, has made obvious this shortage. With this paper, we intend to analyze the students� perception towards this requirement and how they fulfilled it. We have validated and designed an ad hoc questionnaire in order to obtain revealing results regarding these two aspects. We have studied the role of the Language Centers in Higher Education as the ideal tool to perform these duties in the universities. Finally, we have been able to obtain a global picture on how this requirement will be adapted in the new university degrees
The economic impacts of the foreign direct investments: panel estimation by sectors on the case of Macedonian economy

This paper elaborates the economic impacts of the foreign direct investments (FDI) on the case of Macedonian economy. Most developing countries consider FDI a vital source for their development. Anyway, it is quite difficult to measure the economic effects of FDI over the host country, having in mind their numerous direct and indirect effects. Besides the amount of FDI inflows, the economic benefit will also depend on their structure. Based on a panel regression technique, the FDI impacts on GDP, export and employment on the case of Macedonian economy have been estimated, taking into account for their structural dimension. The main conclusion of the analysis is that the FDI inflows were important factor for GDP growth and export performances of the Macedonian economy. On the other hand, the FDI impact over employment is negative mainly due to the low level of green field investments and non attractiveness of the labor intensive industry for the foreign investors. These findings regarding the type and sector distribution of the FDI inflows are very important for the policy makers and imply a need for a strategic approach in this field.
Use of antioxidants on rainbow trout Oncorhynchus mykiss (Walbaum, 1792) sperm diluent: effects on motility and fertilizing capability

The present investigation determined how different antioxidants incorporated into the sperm diluent for cold storage of semen affected sperm motility and spermatozoan fertility capabilities of the rainbow trout. For the evaluations, fresh semen (C) and semen that had been stored without diluents (T1) were used as control groups. The diluents were prepared using a base of UCT diluents (T2), adding grape polyphenol (0.1 g 100 mL -1 ) (T3), trolox C (0.1 g 100 mL -1 ) (T4), polyphenol (0.1 g 100 mL -1 ) plus trolox (0.1 g 100 mL -1 ) (T5), and vitamin C (0.018 g 100 mL -1 ) (T6). The incorporation of antioxidants into sperm diluents prolongs motility and fertility of rainbow trout semen. The results show that by day two, all of the treatments showed level 5 sperm motility. After seven days of storage, only T3 and T6 dropped to level 4 sperm motility. The duration of flagellate activity on this day was maximal for T3 with 36.87 ± 0.51 s and minimal for T6 with 29.78 ± 0.52 s. On day seven, fertility was maintained with no statistically significant differences between the control and T2 (92.80 ± 0.62%), T3 (83.66 ± 2.52%), T4 (90.46 ± 1.60%), T5 (83.57 ± 2.75%), and T6 (83.57 ± 2.30%). By days 10 and 17 of storage, the fertility of T1 was zero and that of T2 was significantly lower than the control group. On day 17, the highest percentage of fertilization was 97.38 ± 1.85% for T5 and the lowest value was 64.69 ± 3.76% for T2. The results allow concluding that the sperm viability of semen stored with different antioxidants is significantly prolonged.
GENE EXPERISON OF CELL PROLIFERATIVE MARKER KI67 IN BREAST CANCER

Background and Objective: Breast cancer is one of the most important malignant tumors world -wide and the second common cancer in the females. Breast cancer is associated with a number of environmental factors and genetic damages. Ki67 is a proto-oncogene which is activated in cell proliferation process. Ki67 is important in prognosis and response to chemotherapy. The aim of this study was to investigate the Ki67 gene expression in patients with breast cancer by immunohistochemistry method. Materials and Methods: This descriptive laboratory study was conducted on 80 breast cancer specimens from patients admitted to the hospitals in Sabzevar, Iran during 2005-09. Samples were fixed in formalin, the tissue processing was done and sections were stained by Hematoxilin and Eosin method. The malignancy was diagnosed by two pathologists blindly. Over expression of ki67 was determined with the immunohistochemistry method. Slides were scored into negative, weak, average and strong based on percentage of cells which were stained. The Data were analyzed by SPSS-11.5, Chi-Square and Fisher’s exact tests. Results: Ki67 proliferative marker was observed in 37 (46.3%) specimens with breast cancer. Sensivity of staining was one positive (+) in 15 cases, two positive (++) in 14 cases and three positive (+++) in 8 cases. There was a significant relationship between Ki67 gene expression and tumor type and tumor staging (P<0.05), but there was no significant relationship between Ki67 gene expression and tumor grade. Conclusion: It is concluded that, ki67 is expressed mostly in invasive and developed breast cancer.
Periodontal Diseases and Possible Future Cardiovascular Events, Are they Related? An Overview

Context: The association between periodontal disease (PD) and cardiovascular disease (CVD) has been evaluated in many epidemiological studies; however, the results are controversial. Herein, we aimed to review if the childhood periodontal diseases are associated with future cardiovascular events or not. EvidenceAcquisition: The current literature regarding childhood periodontal disease and future cardiovascular events in children aged less than 18 years was searched on PubMed, Scopus, ISI, and Google Scholar from January 2005 to March 2017. All studies investigating the association between periodontal disease and CVD were searched by using the following search terms: “coronary artery disease”, “coronary disease”, “heart disease”, “ischemic heart disease”, “myocardial infarction”, Children, “periodontal disease”, and
Lack of Credibility, Inflation Persistence and Disinflation in Colombia

This paper measures inflation persistence in Colombia for the period1990-2010 and estimates the implied speed at which agents learn about the central bank´s inflation target. We estimate Erceg and Levin´s (2003) imperfect credibility model using Bayesian techniques and compare the posterior odds of this model against a conventional Neokeynesian model with ad-hoc price indexation. The odds are strongly in favor of the imperfect credibility model, suggesting that lack of credibility on the inflation target is an important source of inflation persistence. We use the model to compute the sacrifice ratio associated to 100 basis points inflation target shocks and find that it is (0.83%) in line with previous estimates for Colombia. We also find that the speed at which agents learn in the model has increased, albeit marginally, since the central bank implemented its inflation targeting strategy. Although during this period macroeconomic volatility has fallen, inflation persistence has remained roughly constant suggesting that, so far, the impact of those credibility gains on inflation persistence has been modest.
Simulation of Transient Dynamics of Shock Wave Boundary Layer Interactions Using Hybrid Large-Eddy/Reynolds-Averaged Navier-Stokes Models

Abstract : Simulations of the Mach 5 compression-corner shock / turbulent boundary layer interaction experimentally mapped by Prof. David Dolling and co-workers have been performed using a hybrid large-eddy / Reynolds-averaged Navier-Stokes (LES/RANS) model. The model captures the mean-flow structure of the interaction reasonably well, with observed deficiencies traced to an under prediction of the displacement effects of the shock-induced separation region. The computational results provide some support for a recent theory relating to the underlying causes of low-frequency shock wave oscillation. The simulation results indicate that the sustained presence of a collection of neighboring streaks of low / high momentum fluid within the boundary layer induces a low frequency undulation of the separation front. Power spectra obtained at various streamwise stations are in good agreement with experimental results, indicating that the LES/RANS method is capable of predicting both the low and high-frequency dynamics of the interaction. Downstream of re-attachment, the simulations capture a three-dimensional mean flow structure, dominated by counter-rotating vortices that produce wide variations in the surface skin friction. Predictions of the structure of the re-attaching boundary layer agree well with experimental pitot pressure measurements. In comparison with Reynolds-averaged model predictions, the LES/RANS model predicts more amplification of Reynolds stresses and a broadening of the Reynolds-stress distribution within the boundary layer that is probably due to re-attachment shock motion.
Does Brand Personality and Perceived Product Quality Play a Major Role in Mobile Phone Consumers’ Switching Behaviour?

This study’s main objective is to explore the antecedents of consumer switching behaviour in the context of mobile industry. At the same time, this study gives a closer focus on the roles that brand personality (BP) and perceived product quality play in customer satisfaction (CS), consumer brand identification and switching behaviour. Using a self-structured questionnaire, 381 usable responses were recorded for data analysis. Exploratory factor analysis (EFA), confirmatory factor analysis and structural equation modelling were employed to analyze the data. The EFA outcome reveals that excitement, competence and sophistication are the most significant qualities predicting BP in the mobile industry’s context. The result demonstrates that BP, indirectly through consumer brand identification and customer satisfaction, has a negative effect on consumer’s switching behaviour intention. Perceived product quality has a direct and indirect relationship with switching behaviour intention. Finally, it is revealed that BP has high impact on perceived product quality’s evaluation as well.
The implications of foreland basins for the causative tectonic loads

The geometry and development of foreland basins, being controlled primarily by flexure in front of ad- vancing orogenic wedges, contain information about these causative loads. Modeling of the flexure allows estimating the relations between basin width and depth and the taper angle of the orogenic wedges. These relations allow con- straining the advance of tectonic wedges and their taper an- gle based on the onlap of the basin fill and facies migration and on the thickness of the basin fill. Application of this approach to the Alps and the Acadian orogen of New England illustrates how the record of the as- sociated foreland basins can be used to constrain the history of orogenic wedges and their taper angle. The first case also allows to test this approach, while the second case demon- strates its application to a deeply eroded orogen. In these examples the basin records reveal that the orogenic wedges continued to advance and down-flex the foreland well after the exposed levels of these wedges experienced peak meta- morphism and deformation. The modeling also shows that during these late stages of loading of the foreland the oro- genic wedges maintained or even increased their taper an- gles, even though they were much eroded. As erosion tends to reduce the loads, it follows that concurrent modification of the deeper parts of the wedges must have taken place and compensated for the reduction of the load by erosion. Such inferences regarding the history of orogenic wedges, which can be deduced from the flexural interpretation of foreland basins, may be difficult to obtain otherwise, especially when the structure that existed during basin formation was much obliterated by erosion and modified by subsequent deforma- tion. This shows that integration of the insights that foreland basins provide regarding tectonic loads with information ob- tained from the interior of these loads can improve the un- derstanding of the evolution of mountain chains.
