Lalé, E. (2017). Worker Reallocation across Occupations: Confronting Data

This paper studies the secular behavior of worker reallocation across occupations in the U.S. labor market. In the empirical analysis, we use microdata to construct consistent time series over a forty-five year period, and document that the fraction of employment reallocated annually across occupations is highly stable in the long run. We go beyond description and use an equilibrium model to identify potential changes in the productivity shocks and mobility costs that govern worker reallocation across occupations. We uncover the joint evolution of these factors by deriving a simple mapping between data and the model. Our analysis shows that constant reallocation rates across occupations mask slow-moving increases in the volatility of productivity shocks since the mid-1980s, and a pronounced upward shift in the cost of switching occupations in the period surrounding the Great Recession.
Women-owned sewing businesses in Lagos-State, Nigeria: a study of the factors influencing their business growth

Statistics show that more than 60% of chronically hungry and deprived people are women, and Africa contributes the highest percentage. Entrepreneurship has been theorised a fundamental means for alleviating hunger, poverty and unemployment level prominent among women. However, global women entrepreneurship monitoring institutions have revealed that business closure among women entrepreneurs has been on a consistent rise from 2012 to date. Thus, the debate about factors influencing the business growth of women-owned businesses has been a topical issue in business management. Recently, scholars have advocated for a focus on women-specific constructs: motherhood, meso-and the macro-environment to advance women’s entrepreneurship study. However, existing studies have focused mainly on the negative influence of these women-specific constructs. Therefore, this article investigated how motherhood factor (household/family context), and meso-/macro-environment context positively and negatively influences the business growth of women-owned sewing businesses (WOSBs) in Lagos, Nigeria. This study suggests growth strategies that will improve the negative influences, and how women entrepreneurs can use the positive influences to exploit growth opportunities. Thus, the outcome of this research is beneficial to women entrepreneurs, scholars and policy-makers.
Policy hazards, opportunism and the stock market reaction to the international expansion of telecom firms

This paper analyses the extent to which policy hazards may affect the stock market reaction to internationalisation decisions made by telecommunication firms. Building on transaction cost economics, we predict that the stock market should react negatively to increases in the policy instability in the host country, and that the entry mode should moderate the relationship between policy instability and the stock market reaction to international projects. To test these predictions, we first use the event study methodology to estimate the abnormal returns obtained by firms expanding abroad, and then run several multiple linear regression models to estimate the effects of the policy risk and the mode of entry chosen on these abnormal returns. Our results show that the stock market has not reacted negatively to those international projects carried out in conditions of policy instability. Investors only value policy instability negatively when the entry mode is a total acquisition.
On the second derivative of the sums of trigonometric series

Some representations for the second derivatives of the sums of the cosine or sine trigonometric series are found in terms of the second differences of their coefficients. If for the cosine series we denote its sum by $f(x)$, then it is proved that under certain conditions the function $f'(x)-(a_{1}-2a_{2})x$ is concave or convex on $(0,\pi]$, which demonstrates an adherence of those representations. Also, we have obtained some estimates of the integrals of the absolute values of those derivatives in terms of the coefficients of such series.
Expression Analysis of the Mediators of Epithelial to Mesenchymal Transition and Early Risk Assessment of Therapeutic Failure in Laryngeal Carcinoma

Laryngeal squamous cell carcinoma (LSCC) is an aggressive malignancy which lacks early predictors of prognosis. Here, we hypothesized that expression and prognostic characterization of the critical mediators of epithelial to mesenchymal transition (EMT) may provide key information in this regard. Linear regression and multiple correspondence analyses were performed on immunohistochemical data obtained from 20 invasive tumors. Principal component and unsupervised hierarchical clustering were used to analyze the dataset patterns associating with LSCC metastatic profile. Survival and death risk assessments were performed using Kaplan–Meier and hazard ratio tests. Data mining analysis using CHAID decision tree and logistic regression analysis was applied to define the predictive value of the risk factors of tumor aggressiveness. Our analyses showed, that in invasive LSCC tumors, cells associating with a mesenchymal profile were likely to exhibit enhanced NOS2, TGF-β, and IL-17A expression levels, concomitantly to NF-κB nuclear translocation. IHC data deciphering determined that EMT induction was also linked to the enrichment of the tumors with CD68+ populations and IL-10 signal. Strikingly, dataset cluster analysis showed that these signatures could define distinct patterns of invasive tumors, where NOS2 associated with IL-10 expression, and TGF-β and IL-17A signals associated with MMP-9 activation. Decision tree analysis identified IL-17A as a possible predictor of LSCC aggressiveness. Altogether, our results show that distinct immunological patterns would support the acquisition of EMT features in invasive LSCC and suggest that IL-17A may be useful in the early identification of patients “at-risk” of therapeutic failure.
Many-body corrected tight-binding Hamiltonians for an accurate quasiparticle description of topological insulators of the 
Bi2Se3
 family

We generate many-body corrected tight-binding Hamiltonians for topological insulators of the ${\mathrm{Bi}}_{2}{\mathrm{Se}}_{3}$ family. To this end, we use ab initio calculated parameters extracted from $GW$ calculations, thus capturing many-body exchange and correlation effects, in contrast to previous tight-binding models. We investigate the effect of many-body renormalizations on the electronic structure of bulk and surface states of semi-infinite systems as well as thin films of these materials. It is shown that the $GW$ self-energy correction brings about profound changes not only in the band-gap values but also in the band dispersion around the inverted gaps with respect to standard density-functional theory (DFT). These changes substantially improve the agreement with experiment. We discuss the strong renormalization effect as being a result of the characteristic overestimation of inverted gaps by standard approximations of DFT (opposite to the underestimation of gaps in topologically trivial materials). In particular, we analyze the consequences that these renormalizations have on the dispersions of the topological surface states and on the surface resonances. For reference, the tight-binding Hamiltonians are provided in the Supplemental Material [30].
Causal Relationship Model of EQ and MQ and Environmental Education

The objective was to propose a structural model Emotional Quotient (EQ), Moral Quotient (MQ) and Environmental Education (EE) affecting environmental behavior for global warming alleviation through inspiration of public consciousness. The population was 37,101 undergraduate students of Mahasarakham University in the second semester of academic year 2013. The Multi-stage simple random sampling technique was employed to collect the sample for 400 undergraduate students. The research instrument was a questionnaire, and it was used for data collecting. LISREL was used for model verifi cation. Results illustrated that the structural model confi rmatory factors of Emotional Quotient (EQ), Moral Quotient (MQ) and Environmental Education (EE) were able to explain the variation of endogenous factors of Inspiration of Public Consciousness for Environmental Conservation (IPC) to cause Environmental Behaviors for Global Warming Alleviation (BEH) with 96.00 percent. IPC had the most effect to BEH with 0.69. Consequently, confi rmatory factors of Environmental Education (EE), Emotional Quotient (EQ), and Moral Quotient (MQ), were able to explain the variation of confi rmatory factors of Inspiration of Public Consciousness for Environmental Conservation (IPC) with 88.00 percent. EE was the effect to IPC with 0.49.
Post-partum Amenorrhea among Nepalese Mothers

The objective of this paper is to study the post-partum amenorrhea (PPA) among Nepalese mothers. Data are taken from a sample survey of Palpa and Rupandehi districts. Findings revealed that over 40% and 60% mothers were reported their PPA before six and nine months respectively and three fourth had reported before a year. Mean, median and trimean of PPA was found to be 10.4, 8.4 and 9.2 months for current reporting data while 10.6, 8.8 and 9.4 months for retrospective reporting data. Younger mothers have lower PPA duration than older counter-parts. The increased duration of PPA was found with the increase of birth interval and parity of mothers. PPA duration was found to be positively associated with the breastfeeding and an inversely associated with the level of education and socio-economic status of mothers. Weibull distribution has been found good fit to the data of Nepal for describing the distribution of PPA duration. Average expected waiting time for returning menstruations at delivery was found to be 8.5 and 8.6 months for current and retrospective data respectively. Findings may help policy-makers, planners and researchers to design the policies and programmes for improving maternal and child health and thereby reducing fertility level.
BRENO CESAR PERONI MODULATION OF CHREBP (MLXIPL) GENE EXPRESSION INDUCED BY WHEY PROTEIN CONSUMPTION IN MICE TREATED WITH HIGH REFINED CARBOHYDRATE-CONTAINING DIET CURITIBA

Objective: The effects of a high refined carbohydrate-containing diet (HC diet), as well as the supplementation of whey protein isolate in a high refined carbohydratecontaining diet (HCW diet) and a basal normocaloric and normoglicid diet (BD diet), in the expression of Chrebpα and Chrebpβ in adipose tissue and liver are poorly understood. The objective of this study was to evaluate whether a high refined carbohydrate-containing diet with or without whey protein isolate supplementation, or a basal diet are able to influence satiety, induce changes in Chrebp expression, alter the infiltration of immune cells in adipose tissue and modulate the development of hepatic steatosis in mice. Design and methods: Male Mus musculus Swiss lineage mice were divided into three groups with 10 animals each, and fed three different types of diets: 1) HC diet (HC group), 2) HC diet plus whey protein isolated (HCW group) and 3) basal diet (BD group), in a total of 12 weeks of experiment. At the end of the experiment, food and energy consumption, Chrebpα and Chrebpβ expression in liver and adipose tissue, myeloperoxidase enzymatic activity (MPO) in adipose tissue, as well as liver histological analysis were measured. Results: It was observed that diets can strongly influence the gene expression in both tissues, and that the HCW group was protected from hepatic steatosis, but not HC group. Chrebpβ in the liver had its expression influenced by MPO activity, probably due to mechanisms of low-grade systemic inflammation generated by increased visceral adiposity. Chrebpβ expression was very high in relation to Chrebpα in the liver of the HC group, a pattern that occurs only in a glucose-rich environment, signaling a potential insulin resistance in the peripheral tissues. Conclusions: Diets were able to influence the expression of Chrebp α and β, both in adipose tissue and in the liver. The HC diet appears to induce an increase in the infiltration of immune cells into adipose tissue, and the HCW group was protected from hepatic steatosis. Key-words: Transcription factor. De novo lipogenesis. Whey protein isolate.
Does corporate liquidity affect the M&A decisions and methods of payment? Evidence in ASEAN listed firms

Using a probit model and data of 743 merger and acquisition deals of ASEAN listed firms over the period 2007 to 2017; this research studies the extent that liquidity impacts firms' cash capacity in corporate investing decisions. We examine whether high liquidity firms decide to join a merger and acquisition’s bidding process and whether it affects their choice of payment method. We observe that high liquidity firms have managed their excess cash well through investments, and the probability of being M&A bidders is high. We found that high growth firms are likely to use cash payments in acquisitions. This more strongly affects financially constrained bidders, who face greater opportunity costs in holding cash.

Active Power Filter Shape Class Model Predictive Controller tuning by Multiobjective Optimization

As the share of renewable energy sources (RES) in distribution grids increases, several power quality challenges arise. Due to its intermittent nature, RES lead to voltage and frequency fluctuations in the grid that affect power quality. Moreover, as RES are connected via power converters, there is also a higher harmonic distortion pollution introduced by the switching power electronics involved, (Liang, 2017). A proven solution is the implementation of Active Power Filters (APF), which are able to compensate the unbalanced, harmonic, and reactive components of a load under different supply conditions. In order to achieve the desired compensation characteristics, the selection of an appropriate control strategy is critical, (Kumar & Mishra, 2016). Classic APF control strategies achieve said goals, although with struggles under changing load scenarios with limitations on their operational modes, (Weihe, Cateriano Yáñez, Pangalos, & Lichtenberg, 2018). This paper proposes the use of an advanced model-based control method, i.e. Model Predictive Control (MPC), to improve the performance of APF devices. Model-based control methods allow for better performance when the model of the plant is known before hand or through measurements, the MPC extends this further by introducing a cost function that ensures optimal operation even under constraints, (Maciejowski, 2002).

Identification of Barley Landraces and Wild Barley (Hordeum spontaneum) Genotypes Resistant to Rhynchosporium commune

Barley scald is caused by the fungal pathogen Rhynchosporium commune. This disease causes substantial losses in barley production areas of the world. In this study, seedling resistance of 198 barley landraces, 104 wild barley (Hordeum spontaneum) genotypes and two susceptible Turkish cultivars (Bülbül 89 and Efes 3) to 6 R. commune isolates was assessed in greenhouse experiments. Virulence differences among the R. commune isolates were observed. One sixrowed barley landrace (Yeşilköy 9052) was resistant to all six isolates. Another six-rowed barley landrace (genotype no 17) showed resistant reaction to 5 isolates. Fourteen barley landraces were resistant and susceptible to 4 and 2 isolates, respectively. Twenty seven genotypes of H. spontaneum numbered as 5, 6, 7, 8, 9, 11, 16, 20, 30, 31, 36, 37, 48, 50, 51, 56, 58, 59, 60, 62, 67, 79, 80, 83, 90, 94 and 101 were found resistant to all six isolates of R. commune. Apart from these genotypes, 19 genotypes numbered as 1, 2, 32, 33, 34, 42, 43, 49, 52, 64, 66, 76, 77, 78, 96, 97, 102, 104 and 107 showed resistance to 5 isolates and susceptibility to only 1 isolate. Two susceptible Turkish cultivars Bülbül 89 and Efes 3 were found susceptible to 96% of the scald isolates. Resistant barley landraces and Hordeum spontaneum genotypes can be used as sources of resistance against R. commune.
The Influence of Construal Fit on Entrepreneurial Behavior - An Experimental Study

In an increasingly competitive environment, staying innovative is crucial for most industries. One of the main sources of such innovation in large organizations is the employee. Multiple studies have contributed in this matter including how important commitment and entrepreneurial intention as well as behavior are. Recently, the importance of construal fit building on the construal level theory has been highlighted with regard to the roots of such matters. The present empirical study aims to further understand and advance construal level theory by extending it to the metalevel of perception and looking into how it affects commitment toward the employer and employee entrepreneurial intention as well as behavior. Specifically, I assess the relationship between perceived construal fit and employee entrepreneurial intention and behavior via the mediating mechanism of affective commitment. Additionally, I examine what role regulatory focus plays. Manifested in promotion and prevention focus, it has been hypothesized to modulate different types of behavior. Therefore, the moderating effect of regulatory focus on the foregoing relationship is suggested. A survey among a sample of mostly business students in a Finnish university is conducted. The analysis is based on a final sample of forty-eight students mostly pursuing a master’s degree. A between-subject approach is applied, in which perceived construal fit is manipulated by using vignettes. An exploratory and a confirmatory factor analysis support the suggested model and scales with minor issues regarding discriminant validity. Hierarchical regression analyses yielded partial support for the mediation model with employee entrepreneurial behavior as a dependent variable. Specifically, higher perceived construal fit is associated with higher affective commitment and, in turn, with higher entrepreneurial behavior. This is also supported by the result of the indirect effect displayed in Hayes’ PROCESS tool. The mere perception of construal fit is thus supported as a mechanism. However, such support is neither found for entrepreneurial intention nor for any moderated mediation model. A post-hoc analysis further lends support to these results while also suggesting that both types of regulatory focus may play a positive role. Notwithstanding a few limitations, this study hence generates insights into the mechanism of the interplay of construal levels, including an extension to the mere perception of it, affective commitment and entrepreneurial intention as well as behavior.
Platelet Rich Fibrin Combined with Nano Crystalline Hydroxyappatite in Treatment of Grade II Mandibular Furcation Defect

Aim: This study aims to evaluate the effect of Platelet Rich Fibrin combined with Nano crystalline Hydroxy appatite bone graft on grade II mandibular furcation involvement. Subjects and methods: Thirty patients having grade II mandibular furcation defects, with vertical probing depth (VPD) ≥5mm and horizontal clinical attachment level (HCAL) ≥3mm. Following phase I therapy were classified into two groups, group1 received NcHA bone graft and group 2 received NcHA+PRF. Clinical and radiographic parameters were recorded at baseline, 6 and 12 months postoperatively. Results: Both treatment groups showed a significant probing pocket depth (PPD) reduction, clinical attachment gain, increase bone density 12‑months after surgery compared with baseline. However, there was a highly significant PPD reduction and clinical attachment gain when PRF was added to NcHA. Conclusion: The NcHA bone graft in combination with PRF demonstrated clinical advantages beyond that achieved by the NcHA alone.
Fracture of the Femoral Component Caused by Insufficient Crimping after Modern Unicompartmental Knee Arthroplasty

Fracture of a femoral component after modern unicompartmental knee arthroplasty is very rare. Although this is not the first case on this subject, no study has reported insufficient crimping as the cause of femoral component loosening that led to breakage of a metallic component. A 69-year-old man underwent medial unicompartmental knee arthroplasty for right medial knee osteoarthritis. His early postoperative course was good; however, the 1-year postoperative radiograph showed an apparent radiolucent line around the femoral component, and he occasionally had right knee pain. However, he had been followed up conservatively because he had been doing well even while doing heavy agricultural work. At 8 years after surgery, because breakage of the femoral component was found, revision surgery was performed using bicruciate-retaining total knee arthroplasty. The removed fractured femoral component revealed a thick cement mantle detached from the bone surface. The postoperative course of the patient after the revision surgery was excellent. We suggest that the causes of femoral component breakage include early implant loosening caused by uneven cement crimping of the femoral component to the bone and excessive loading stress as a result of heavy labour.
