Ethical leadership, perceived organizational support and citizenship behaviors

Purpose Utilizing organizational support theory, the purpose of this paper is to examine the mediation effect of perceived organizational support (POS) on the relationship between ethical leadership and citizenship behavior, and investigate the moderating effect of ethnic dissimilarity in the research model. Design/methodology/approach Using a self-administered questionnaire, data were collected from 294 academics of private universities in China, Malaysia and Thailand. The collected data were analyzed using partial least squares path modeling technique on R platform. Findings The study found that ethical leadership is significantly and positively related to POS, which, in turn, related to both distinct dimensions of organizational citizenship behaviors – individual and organization. However, further analysis reveals that ethnic dissimilarity does moderate the hypothesized relationships in the research model, in which POS is found to have a mediation effect in the heterogeneous sample but not in the homogeneous sample in terms of ethnic dissimilarity. Originality/value To the best knowledge of the researchers, this study is among the first few research works examining the interrelationships of ethical leadership, POS, and citizenship behavior in terms of individual and organizational. Moreover, this is one of the earliest studies to examine the concepts in two different samples in terms of ethnic dissimilarity.

The downward transport of momentum to the surface in idealized sting‐jet cyclones

Processes leading to the formation of strong surface wind gusts within an idealized sting‐jet extratropical cyclone are investigated using a high‐resolution mesoscale model. It is motivated by real case studies that have shown that damaging surface winds ahead of the bent‐back warm front of an extratropical cyclone are often due to the presence of a sting jet, which is a low‐level mesoscale jet, the air masses of which descend from the cloud head to the top of the boundary layer. Different numerical simulations show that surface winds below the leading edge of the sting jet increase with increased horizontal resolution and surface roughness. For typical land‐surface roughness, the intensity of near‐surface wind gusts increases rapidly with horizontal resolution, while the sting‐jet intensity above the boundary layer does not vary with resolution. A focus on the 1‐km grid‐spacing simulation with land‐surface roughness is then made. It shows stronger surface winds ahead of the bent‐back warm front than near the cold conveyor‐belt jet. It also exhibits multiple bands of strong surface wind speed, similar to real sting‐jet cyclones. These multiple bands are closely linked with multiple resolved convective rolls in the boundary layer, the descending branches of which are responsible for the downward transfer of momentum. Sensitivity experiments and a stability analysis show that cooling due to sublimation and melting of precipitating ice hydrometeors below the leading edge of the sting jet triggers and invigorates boundary‐layer convective rolls by reducing the buoyancy of air masses near the precipitation base and below. Closer to the surface, the transfer of momentum is predominantly taken over by subgrid‐scale turbulent fluxes.
Estimating Electron Temperatures in Ionized Nebulae: The Direct Method and its Limitations

In this paper we examine the Direct Method for measuring electron temperatures in H ii regions, and the extent to which such measurements can provide meaningful information on the physical conditions in these regions. We discuss the limits to what can be inferred about electron temperatures from nebular emission line fluxes. We provide a new simplified method for estimating electron temperatures, including parameters that can be used to determine this from UV [O iii] and [O ii] oxygen lines observable in high-redshift objects using ground-based telescopes. We test this method on published UV high redshift observations and compare the results with reported electron temperatures.
Early-life environmental enrichment generates persistent individualized behavior in mice

Experience-induced differences in behavior, brain plasticity, and epigenetics persist even after stimulus withdrawal. Individuals differ in their response to environmental stimuli, but the stability of individualized behaviors and their associated changes in brain plasticity are poorly understood. We developed a novel model of enriched environment to longitudinally monitor 40 inbred mice exploring 35 connected cages over periods of 3 to 6 months. We show that behavioral individuality that emerged during the first 3 months of environmental enrichment persisted when mice were withdrawn from the enriched environment for 3 additional months. Behavioral trajectories were associated with stable interindividual differences in adult hippocampal neurogenesis and persistent epigenetic effects on neuronal plasticity genes in the hippocampus. Using genome-wide DNA methylation sequencing, we show that one-third of the DNA methylation changes were maintained after withdrawal from the enriched environment. Our results suggest that, even under conditions that control genetic background and shared environment, early-life experiences result in lasting individualized changes in behavior, brain plasticity, and epigenetics.
The Enhancement Difference of Eight Grade Students' Mathematical Problem-Solving Ability

— The aims of this research are to analyze: the difference of the improvement mathematical problem-solving ability between students taught by guided discovery learning with the students taught by expository learning, and the interaction between mathematics learning with students 'early mathematical abilities on students' mathematical problem-solving abilities. This study is quasi experiment study. The population of this study was the 8th grade students of MTsN Stabat. Then, the sample was taken by using random sampling method, with VIII-1 were chosen as experiment 1 class and VIII-2 as experiment 2 class. The experiment 1 class was treated by using guided discovery learning while the experiment 2 class was by using expository learning. The result of this study shows that: there is enhancement difference of student mathematical problem-solving ability taught by guided discovery learning and taught by expository learning, and there is no interaction between the learning and the initial ability (high, medium, low) on students' mathematical problem-solving abilities.
Childhood socio-economic circumstances, cognitive function and education and later-life economic activity: linking the Scottish Mental Survey 1947 to administrative data

As the population ages, older adults are expected to work for longer into the life course. However, older adults experience particular problems staying economically active, even prior to reaching statutory retirement. Recent work has suggested that economic activity in midlife can be predicted by the far-reaching effects of early life, such as childhood socio-economic circumstances, cognitive ability and education. The present study investigates whether these same early-life factors predict the odds of being economically active much later in life, from age 55 to age 75. We capitalise on data linkage conducted between a subsample of the Scottish Mental Survey 1947 cohort and the Scottish Longitudinal Study, which includes three waves of national census data (1991, 2001 and 2011). The structural association between early-life factors and later-life economic activity was assessed using latent growth curve analyses conducted for males and females separately. In both males and females, the odds of being economically active decreased non-linearly across the 20-year follow-up period. For males, greater odds of being economically active at age 55 were predicted by higher childhood cognitive ability and higher educational attainment. For females, greater odds of being economically active at age 55 were predicted by higher childhood socio-economic status and higher childhood cognitive ability. In contrast, early-life factors did not predict the odds of becoming inactive over the 20-year follow-up period. We suggest that early-life advantage may contribute to the capacity for work in later life, but that it does not necessarily protect from subsequent decline in this capacity.
Prediction of long-term complications of venous thromboembolism

The post-thromotic syndrome (PTS) and chronic thromboembolic pulmonary hypertension (CTEPH) are the most feared long term complication of a deep venous thrombosis (DVT) and pulmonary embolism (PE) respectively. We have reviewed the literature on arguments for and against routine screening of CTEPH in patients after an episode of an acute PE. The incidence of CTEPH is relevant in this evaluation. In a systematic review and meta-analysis we showed a CTEPH incidence of 0.56% in all comers and of ~3% in the survivors. We showed that a very recent developed screening algorithm, the InShape II algorithm, is sensitive and reproducible for detecting early CTEPH in the course of an acute PE. Beside this, most patient who were diagnosed with CTEPH in the course of an acute PE already showed signs of CTEPH on the initial CT scan made for PE diagnosis.In the last chapter we focus on PTS in the course of a DVT. In patients included in the MEGA database the 0-1 year incidence was 21.8%, after 8 years of follow-up an additional 7% developed PTS. During follow-up PTS symptoms improves in almost 70% of patients.
The Trouble with Race in Forensic Identification

The capacity of contemporary forensic genetics has rendered “race” into an interesting tool to produce clues about the identity of an unknown suspect. Whereas the conventional use of DNA profiling was primarily aimed at the individual suspect, more recently a shift of interest in forensic genetics has taken place, in which the population and the family to whom an unknown suspect allegedly belongs, has moved center stage. Making inferences about the phenotype or the family relations of this unknown suspect produces suspect populations and families. We discuss the criminal investigation following the Marianne Vaatstra murder case in the Netherlands and the use of forensic (genetic) technologies therein. It is in many ways an interesting case, but in this paper, we focus on how race surfaced in science and society. We show that race materializes neither in the technologies used nor in the bodies at stake. Rather, race emerges through a material semiotic relation that surfaces in the translation that occurs as humans and things move across sites. We argue that race is enacted, firstly, in the context of legislation as biology reduced to bodily characteristics; secondly, in the forensic analyses as patterns of absent presence; and, thirdly, in society as a process of phenotypic othering.
Risk factors for neonatal hyperbilirubinemia: a case control study

Background: Neonatal Hyperbilirubinemia is one of the most common reasons for NICU admissions. The frequency of neonatal jaundice has been on an increase since the last decade. Is the increase due to changes in obstetric practice or drugs? There is no definite reason. This study was undertaken to find out any obstetric characteristics which may contribute to the development of Neonatal Hyperbilirubinemia and which is modifiable. Methods: Record review data from 140 singleton deliveries at the Institute of Maternal & Child Health ,Govt. Medical College, Kozhikode, Kerala were analyzed to determine the relationship between neonatal hyperbilirubinemia (>10mg/dl) and maternal characteristics. Confounding variables were controlled by multiple logistic regression analysis. Results: There was statistically significant relationship between hyperbilirubinemia and LBW, preterm delivery, PPROM, breast feeding, neonatal infection, instrumental delivery and presence of GDM and IUGR. Conclusions: By identifying these obstetric characteristics, we may be able to modify them and reduce the need for NICU admissions for Neonatal Hyperbilirubinemia.
Toward the Best Model of Purchase Decision Through Online Store in Indonesia from the Lens of Price Perception, Service Quality and Marketing Communication

This study aims to discuss the effect of purchasing decisions online in the marketplace. The object of research is a seller who has a good reputation and significant transactions in selling in Bukalapak e-commerce. The independent variables obtained from the preliminary survey results to the buyer are the perception of price, service quality, and marketing communication. This study uses SEM data analysis techniques and data processing using PLS. The population is e-commerce Bukalapak customers who shop at Farqi Cellular stores, with a sample of around 162 respondents. The results of testing the data using SmartPLS 3.0 software found that the perception of price has a positive relationship and no significant effect, service quality and marketing communication have a positive relationship and have a significant effect on online purchasing decisions. With the R-square value (R2) = 0.729 shows that the ability of the independent variable (perception of price, service quality, marketing communication) in explaining the dependent variable variance (online purchase decision) is 72.9%. While the remaining 27.1% is explained by other factors outside the model.
Freeze tolerance and genetic variability of Acacia koa A. Gray, a key Hawaiian tree species

Koa (Acacia koa A. Gray) is a charismatic tree species endemic to Hawaii that plays an important role, socioeconomically, culturally and ecologically in the Hawaiian Islands. Koa forests in Hawaii have been heavily depleted and degraded due to harvesting and land use changes. To contribute to the success of koa restoration initiatives, two research projects were conducted as part of this thesis. The first project consisted of analyzing the freeze tolerance of seedlings from koa populations distributed across an elevational gradient, while the second project involved determining heritability estimates and the genetic gain of traits within and among high-elevation koa families in progeny trials. In the first project (Chapter 2), the objective was to determine if different ecotypes of koa show variation in freeze hardiness as a mechanism to tolerate cold and if exposure to hardening conditions prior to frost exposure can modify such cold tolerance adaptation. Thirteen populations of koa (Acacia koa A. Gray) were grown from seeds collected across an elevational range from 603 m to 2050 m on the Island of Hawai’i. Four-month-old greenhouse-grown seedlings obtained from these seeds were then divided into control seedlings (maintained at 25 °C day, 22 °C night) and chilling-acclimated seedlings (held at 8 °C day, 4 °C night). After six weeks, ten acclimated and ten non-acclimated seedlings per population were tested for freeze tolerance by electrolyte leakage at temperatures from 5 °C to –20 °C. Results showed a higher index of cold damage in the non-acclimated seedlings for most of the populations at the two lowest test temperatures. There were some differences in the index of damage among the population elevations, depending on the test temperature. In the second project (Chapter 3), the objective was to determine if there is genetic variability among 20 koa families for height, basal diameter, and other parameters of interest, measured at 4 years of age, at a high-elevation progeny trial site on the windward slopes of Mauna Kea on the Island of Hawai’i. Height, basal diameter, height to living crown, and projected crown area showed significant differences among families. The estimates of heritability of family means were higher than the estimates of individual-tree heritability for height, projected crown area, and gross crown volume, yet showed the same value of the estimates of individual-tree heritability for basal diameter and live crown ratio. Height, basal diameter, and height to live crown had relatively high heritability estimates > 0.4. There were significant differences among the tested families in height, basal diameter, height to living crown and projected crown area. The relative performance rankings among families produced from this progeny test will allow forestry managers to make selections for relatively high performing koa families to supply regionally-adapted, improved koa seeds for reforestation in the vicinity of this test site.
Diode laser versus conventional technique for frenectomy- A randomised controlled clinical trial

Aim: Diode lasers are most commonly used for oral soft tissue surgeries. The aim of this randomised controlled clinical trial was to evaluate the use of diode laser for frenectomy on clinical and healing outcomes. Materials and Method: Twenty patients aged between 18 to 45 years were selected requiring frenectomy of maxillary labial frenum were randomly assigned to either test group or control group. For test group soft tissue diode laser was used for frenum removal and for control group conventional scalpel technique was used. Clinical and healing outcomes were measured using for pain (visual analogue scale), discomfort during speech, bleeding severity, swelling, redness and wound healing. Recall visits were done at 1, 7 and 30 days. Results: The clinical and healing outcomes were statistically significant for diode laser group. There was less pain, discomfort during speech and increased healing on the test sideat 1 and7 days recall visit. Bleeding and redness immediately after surgery was less on the test side than on the control side. Conclusion: The use of soft tissue diode laser could be an alternative to conventional scalpel technique for maxillary labial frenectomy as it causes less pain, less bleeding and improved healing of tissues.
IDENTIFICATION OF HOMOGENEOUS RAINFALL ZONES DURING GRAIN CROPS IN PARANÁ, BRAZIL

The aim of this study is to identify homogeneous rainfall zones in the winter and summer 1 st and 2 nd crops, in the state of Paraná, Brazil. The zones were defined by clustering using the expectation-maximization (EM) algorithm to transform seasonal rainfall series. Monthly average rainfall data collected from 157 weather stations for 20 years (1996 to 2015) were employed. The results show that the number of homogeneous zones varied among growing seasons. The summer crop presented two clusters, with rainfall averages of 1489 a

Teenage Pregnancy: Prevalence, Pattern and Predisposing Factors in a Tertiary Hospital, Southern Nigeria

Background: Any pregnancy occurring in a young woman who has not reached her 20th birthday is considered as a teenage pregnancy. Globally, approximately a tenth of all births are to women younger than 20 years old and more than 90% of such births occur in developing countries. Socioeconomic deprivation, low contraceptive usage and early marriage are common contributing factors. Objective: This study aimed to determine the prevalence, pattern and predisposing factors to teenage pregnancy at University of Port Harcourt Teaching Hospital (UPTH), Port Harcourt, Nigeria. Methodology: This was a retrospective cross-sectional study of 198 cases of teenage pregnancies managed at University of Port-Harcourt Teaching Hospital (UPTH), from 1st January 2008 to 31st December 2015. Results: The teenage pregnancy prevalence rate was 15 per 1,000 deliveries (1.5%). Low level of education (below secondary) was seen in 81.3% of the women. A socio-cultural factor like early marriage was noted in 56.1% of the women and only 26.8% of the teenage mothers had ever used any form of contraception. Conclusion: The teenage pregnancy rate in Port-Harcourt showed a downward trend. Contraceptive awareness creation for teenagers, implementation of teenage-friendly policies, education of the girl child coupled with promotion of moral and sex education will further reduce the trend.
Smoking Behaviour in Germany: Evidence from the SOEP

As in most OECD countries, smoking prevalence and cigarette consumption have been decreasing in Germany since the early 2000s. This paper analyses whether smoking prevalence and cigarette consumption, as well as their development over time, differ between socio-economic subgroups. Identifying these differences provides insights into the effect of policy interventions on German smoking behaviour. Based on data from the Socio-Economic Panel (SOEP), a large longitudinal study of the German population, we find that both the decline in smoking prevalence and the decline in average cigarette consumption were probably driven by a behavioural change of younger people, as well as of those with a high educational level and those with a high income. People who quit smoking were on average more highly educated, had a higher income and had most likely a lower cigarette consumption (before quitting). In contrast, smoking prevalence increased among people who were older than 45 and had a low educational level and among those who were unemployed. Smoking prevalence among women was relatively constant over time. Indeed, the smoking prevalence of women and men converged over time, especially in older age groups. Daily cigarette consumption of smokers increased among 66-to-75-year-olds, although it decreased in all other age groups. One explanation might be that the tobacco control measures were successful only in certain socio-economic subgroups. Not only smoking prevalence, but also smoking intensity was higher among men, among those with a lower educational level and among those with a lower income. Especially for younger birth cohorts, smoking prevalence among those with a lower educational level was particularly high. Thus, based on data from 1998 through 2014, the so-called social gradient in smoking was only a distinct feature of younger birth cohorts, and not of older ones.
