Transformational Leadership and Employee’s Behavioral Support for Organizational Change

The successful implementation of organizational change has become an important management task, given that countless companies fail to implement organizational changes successfully in recent decades. Further, there has been a lack of empirical research on the role of transformational leadership in a change context per se. In this regard, the present study aims to fill this gap by conducting an empirical research in hopes of contributing to a better understanding of the inner workings of employees’ supportive attitudes and behavior toward change by investigating the relationship between transformational leadership and employee’s behavioral support for organizational change. The results from a sample of 448 respondents in Taiwan provide additional insight into the mechanism through which transformational leadership influences behavioral support for organizational change. Key words: Transformational leadership; self-efficacy; affective commitment to change; behavioral support for change.
Unsteady asymmetric engulfment regime in a T-mixer

Unsteady flow regimes in a micro T-mixer are investigated. Direct numerical simulations (DNS) show that, in agreement with experimental and numerical results in the literature, when the Reynolds number is increased above a critical value larger than those typical of the steady engulfment regime, the flow remains asymmetric in the mean but becomes periodic in time. The dynamics of this regime is characterized by analyzing the evolution of the three-dimensional vortical structures forming at the confluence of the two inlet flow streams. As the Reynolds number is further increased, the flow remains time-periodic but it continuously switches between a symmetric configuration, similar to that of the vortical regime, and an asymmetric one, close to the engulfment configuration. Three-dimensional linear stability analysis is successively used to characterize the instability leading to the unsteady asymmetric regime, which is also interesting for applications due to its high mixing efficiency. The critical Reynol.
SIMILARITY-BASED CLASSIFICATION IN PARTIALLY LABELED NETWORKS

Two main difficulties in the problem of classification in partially labeled networks are the sparsity of the known labeled nodes and inconsistency of label information. To address these two difficulties, we propose a similarity-based method, where the basic assumption is that two nodes are more likely to be categorized into the same class if they are more similar. In this paper, we introduce ten similarity indices defined based on the network structure. Empirical results on the co-purchase network of political books show that the similarity-based method can, to some extent, overcome these two difficulties and give higher accurate classification than the relational neighbors method, especially when the labeled nodes are sparse. Furthermore, we find that when the information of known labeled nodes is sufficient, the indices considering only local information can perform as good as those global indices while having much lower computational complexity.
Revisiting Problem Gamblers’ Harsh Gaze on Casino Services: Applying Complexity Theory to Identify Exceptional Customers

This study revisits the theory, data, and analysis in Prentice and Woodside (2013). The study here applies fuzzy-set qualitative comparative analysis (fsQCA) to customer service–evaluation data from seven mega casinos in the world's gambling capital—Macau. The study includes contrarian case analysis and offers complex algorithms of highly favorable customer outcomes—an alternative stance to theory and data analysis in comparison to the dominant logic of statistical analyses that Prentice and Woodside (2013) report. Contrary to their principal hypotheses, Prentice and Woodside (2013) report a negative main effect between problem gambling and casino service evaluations. The findings in the reanalysis here include more complex, nuanced views on the antecedent conditions relating to high problem-gambling, immediate service evaluations, and desired customer behavior measures in casinos. Counter to the findings using symmetric testing via multiple regression analysis in Prentice and Woodside (2013), the present study, using asymmetric testing via fsQCA, recognizes the occurrence of causal asymmetry, and draws conclusions from different algorithms leading to high scores for favorable and unfavorable outcome conditions. The findings indicate that not all problem gamblers gaze on casino services harshly; the minority of problem gamblers who view casinos positively versus harshly may be the most valuable customers for the casinos—the casinos’ exceptional customers.
RESEARCH OF WASTEWATER TERTIARY TREATMENT

The article analyzes tertiary wastewater treatment in semi-industrial conditions. During the study, experimental equipment containing three trickling filters was installed in Nemencinė WWTP. The filters were filled with three different media. The biologically treated wastewater was continuously supplied to the filters maintaining the same surface load – 0.07 m 3 /m 2 /min. According to the results, the highest removal efficiency of COD, BOD 7 and SS was reached in filter 1 that contained the stone wool Growcube media. DOI: https://doi.org/10.3846/enviro.2017. 075
Spatial prediction of coral reef habitats: integrating ecology with spatial modeling and remote sensing

Spatial prediction of coral reef habitats and coral reef community components was approached on the basis of the 'predict first, classify later' paradigm. Individual community compo- nents (biotic and geomorphologic bottom features) were first predicted and then classified into com- posite habitats. This approach differs from widely applied methods of direct classification based on remote sensing only. In situ coral reef community-condition assessment was first used to measure a response variable (percentage cover of habitat). Reef bottom features (topographic complexity, sand- sediment, rock-calcareous pavement and rubble) were then predicted using generalized additive models (GAMs) applied to continuous environmental maps, high-resolution Ikonos satellite images and a reef digital topographic model (DTM). Next, using GAMs on newly created bottom maps, mod- els were fitted to predict coral community components (hard coral, sea-grass, algae, octocorals). At this stage, high-resolution maps of the geomorphologic and biotic components of the coral reef com- munity at an experimental site (Akumal Reef in the Mexican Caribbean) were produced. Coral reef habitat maps were derived using GIS following a hierarchical classification procedure, and the result- ing merged map depicting 8 habitats was compared against thematic maps created by traditional supervised classification. This general approach sets a baseline for future studies involving more complex spatial and ecological predictions on coral reefs.
Reconstructing economics: Agent based models and complexity

In this paper we argue that a view of the economy as a complex interactive and adaptive system allows one to explain phenomena such as “phase transitions” which are not consistent with the equilibrium models of standard models. A growing strand of economists is now following a different methodology based upon the analysis of systems with many heterogeneous interacting agents. We explain how Agent Based Models (ABM), and, in particular Agent based Computational Economics (ACE), and Analytically Solvable Heterogeneous Interacting Agent (ASHIA) models based on statistical physics or Markov chains can be used to deal with economies in which direct interaction between agents is important. This interaction leads to empirical regularities, which emerge from the system as a whole and cannot be identified by looking at any single agent in isolation: these emerging properties are, according to us, the main distinguishing feature of a complex system. In this way economics can free itself from the limitations of the static equilibrium approach, the use of the implausible Representative Agent approach and analyze the, possibly out of equilibrium, dynamics which seem more consistent with observed empirical data. The complexity approach is a very challenging line of research whose empirical results are very promising. Modeling an agent-based economy, however, remains a complex and complicated adventure.
Stimulated immune response by Morinda tinctoria methanol leaf extract in a Vibrio parahaemolyticus infected fresh water crab, Oziotelphusa senex senex

The crab, O.senex senex was injected with V.parahaemolyticus (0.1 ml of 10 7 cfu/ml). After injection of bacteria the crabs were allowed to withstand for 96 hrs. After 96 hrs one group of crabs were dissected, some tissues and haemolymph were used for biochemical assays. Remaining bacterial injected crabs were treated with 0.05 ml of 80% M. tinctoria leaves methanol extract (1000 ppm), after 96 hrs total protein, microprotein increased in the experimental group. Glucose, acid phosphatase and alkaline phosphatase significantly decreased in the experimental group. These result suggested that the M.tinctoria could combat the microbial infection by stimulating the immune response in crabs.
Postweaning growth of the non-carcass components of Texel crossbred lambs

Vinte cordeiros 11/16 Texel x 5/16 Ile de France foram abatidos em diferentes pesos com o objetivo de avaliar o crescimento dos componentes nao-integrantes da carcaca. Os animais foram desmamados aos 42 dias de idade (15,9 ± 2,1 kg de peso corporal) e confinados em baias individuais, recebendo alimentacao a vontade. Apos um periodo de 10 dias de adaptacao as condicoes experimentais, 5 cordeiros foram abatidos e os remanescentes foram aleatoriamente sorteados para serem abatidos aos 25, 30 ou 35 kg de peso corporal em jejum. Ao abate, cada componente corporal foi pesado individualmente, e seus valores expressos em percentual do peso de corpo vazio (PCV). Para determinacao do crescimento alometrico de cada componente, foi utilizada a equacao exponencial Y = aXb, transformada logaritmicamente em um modelo linear. As proporcoes de patas e cabeca decresceram, e a de la aumentou linearmente de acordo com o peso de abate. Observou-se acentuado acumulo de gordura interna (renal e mesenterica) no corpo dos animais abatidos em pesos mais elevados. A taxa de crescimento do intestino delgado foi menor que a do corpo vazio (b = 0,39) o que reduziu a proporcao desse orgao com o avanco da maturidade. O crescimento do figado e do intestino grosso foi isogonico, ou seja, equivalente ao do corpo vazio (b = 0,90 e 1,08, respectivamente), enquanto o rumen foi heterogonico e tardio (b = 1,37). Menores proporcoes de rumen foram observadas apenas para os animais abatidos logo apos o desmame (1,58%). Tendo em vista que pesos de abate mais elevados resultam em maior acumulo de nutrientes em regioes do corpo nao-destinadas ao consumo humano, recomenda-se que o abate de cordeiros 11/16 Texel x 5/16 Ile de France seja realizado com, no maximo, 30 kg de peso vivo.
QTC is Associated with Obesity and Physical Activity Level for African American Females

QTc IS ASSOCIATED WITH OBESITY AND PHYSICAL ACTIVITY LEVEL FOR AFRICAN AMERICAN FEMALES. C Jayne Brahler. JEPonline 2004; 7(2):16-24. Long QT syndrome (LQTS) is an independent risk factor for cardiovascular or ischemic disease mortality. Obesity as a cause for acquired LQTS in otherwise healthy individuals is rapidly gaining the attention of the scientific community. African American people have a higher incidence of obesity compared to Caucasians, yet race-specific information is not available for their prevalence of LQTS. Chronic physical activity can help reduce the incidence of obesity, yet little is known about the effects of chronic physical activity on acquired LQTS. Subjects in this study were a volunteer sample of African American mothers (21-53 yr, n = 44) and daughters (5-17 yr, n = 66) recruited from the inner city Dayton, Ohio community using posters placed in a local agency that provides assistance for mothers with children. Electrocardiograph (ECG) tracings were drawn, and body weight and height were measured without shoes. Body mass index (BMI) was calculated (weight in kilograms divided by height in meters squared). Each subject completed an interviewer administered physical activity questionnaire. QTc (QT interval corrected for heart rate) data were grouped according to subject body mass index (BMI) for normal weight (BMI 30) and statistically analyzed using an ANOVA test to determine if QTc duration was significantly different between BMI groups. Correlation tests were run between physical activity level and QTc, and between mothers’ and daughters’ QTc. Results indicated a longer QTc for obese mothers and daughters compared to normal-weight mothers and daughters (p = 0.003). Selfreported PA was inversely associated with QTc for mothers and daughters, but reached statistical significance (r = -0.46; p < 0.001) for the obese daughters only. Mother and daughter QTc durations were significantly and positively correlated (r = 0.42; p < 0.0001). These results indicate a positive association between obesity and QTc and an inverse association between PA and QTc.
Does The Specification of A New Class of Poverty Measures Matter? Evidence from Tunisia

The evaluation of the horizontal inefficiency of an anti-poverty design is often reduced to the determination of the type I errors, which occur where eligible individuals are not awarded benefits. Because under-coverage ratio does not consider the social cost resulting from unequal treatment of like individuals, it is irrelevant in assessing the severity and the depth of horizontal inefficiency. Also, when the cost of inequality approach is adopted to derive from a poverty measure, respecting the transfer axiom, a cost of inequality that is decomposable into two components, corresponding to vertical and horizontal inequality respectively, it is no longer possible to have different aversions toward these two forms of inequality. We follow then the cost of inequality approach after specifying a new class of poverty measures, which are parameterized by two coefficients allowing so different preferences toward these two equality principles. When these two coefficients are identical, the new poverty measures class reduces to the Foster, Greer and Thorbecke? s (1984) class, whose poverty measures imply the same aversion to vertical inequality and horizontal inequity. Further, for a given poverty line, the new class enables to characterize the set of poverty measures in which policymakers are indifferent between the post-reform poverty alleviation program and the status quo.
How Do Drug Prices Respond to a Change from External to Internal Reference Pricing? Evidence from a Danish Regulatory Reform

We study the effects of a change in the way patient reimbursements are calculated on the prices of pharmaceuticals using quasi-experimental data for Denmark which switched from external (where reimbursements are based on prices of similar products in foreign countries) to internal reference pricing (where they are based on the cheapest domestic substitute). We analyze three therapeutic classes with different treatment durations and show that the reform led to substantial price decreases for our lifelong treatment and to less substantial price reductions for our medium duration treatment while we do not find significant effects on our acute treatment. Moreover, the reform did only affect generics and did not impact original products or parallel imports.
Vanishing hands? On the link between product and organization architecture

The present article investigates whether modular product architectures deliver better and more differentiated products, given their production in disintegrated and integrated settings. A theoretic model benchmarks the performance of disintegration and integration for different degrees of product modularity by measuring both product quality and differentiation. In line with conventional wisdom, (nearly) modular products befit disintegration insofar as disintegration increases quality. However, disintegration only leads to greater product differentiation than integration if there is substantial entry and exit. These findings--albeit developed with stylised models of disintegration and integration--provide a possible explanation for empirical results showing a decrease in product variety when modular products were produced by independent manufacturers (disintegration). Moreover, the model results predict that industries with limited entry and exit as well as strong winner-take-all dynamics tend to incur a loss in variety if modular products are produced in a disintegrated setting.

Effects of Aspect Ratios on Flow Friction and Thermal Behavior Inside a Close Domain Using Lattice Boltzmann Method

Numerical study of flow friction and thermal behavior on a moving lid of a triangular cavity with various aspect ratios has been discussed using a Thermal Lattice Boltzmann Method (TLBM). To analyze the combined force and free convection, known as mixed convection, flows and heat transfer process in a lid driven triangular cavity with various aspect ratios AR(=L/H)=0.5, 1.0 and 2.0 are taken into account in the present study. The results are presented as stream function in terms of velocity, average heat transfer rate in terms of Nusselt number (Nu), and friction on moving lid of cavity for different Reynolds number (Re) as well as buoyancy parameter (λ). The heat transfer rate and friction on moving lid increased and decreased significantly with increasing Reynolds number and aspect ratios but they are linearly and very slowly changed with buoyancy effects. Similarly, the fluid flow behavior significantly changed with higher Reynolds number and aspect ratios compare to lower Re and AR. In addition, the less friction and more heat transfer occurred at case of free convection dominant case compare to forced convection dominant case. Similar behavior is observed for fluid flow analysis inside cavity. The model is validated by other numerical scheme and a very good agreement is found.
Landfill leachates as an abiotic disease factor affecting solanaceous crops and olive trees

Different landfills in Jenin district were selected in this research, and are considered the main garbage destination for the north part of the West bank. Due to their expected drastic effect on agriculture, the experiment was carried out to study the impact of such landfills on nearby olive orchards. The results showed that the landfills since their establishment caused drastic reduction of olive production from an average of 1500 kg/hectare in 2005 to 560 kg/hectare in 2009. Furthermore, olive production in the studied area stopped absolutely in 2011 due to complete olive orchard failure. On the other hand, the effect of landfills was studied on vegetables under lab conditions. Therefore, different dilutions of the landfill leachate were used to irrigate tomato and pepper plants. The results showed that leachate caused plant stunting and reduction in leaf surface area when compared with control regardless of dilution used, but more pronounced in dilution zero. On the other hand, chlorophyll concentration was more in plant treated with zero dilution of leachate when compared with other treatments. Number of dropped leaves was more in plant treated with zero dilution of leachate when compared with other dilutions and control. The plants treated with zero dilution died before others treatments. Conclusion: leachate may have a drastic effect on nearby cultivated plant and could affect plant growth and lead to premature plant death.
No short term effect of Clinostomum complanatum (Trematoda: Digenea: Clinostomatidae) on survival of Triturus carnifex (Amphibia: Urodela: Salamandridae)

In this paper we evaluated the effects of the metacercariae of C. complanatum on body condition and survival probability of the Italian crested newt. We studied two populations of T. carnifex , with one of the two infected by the trematode, in central Italy, for a year. We found that: i) paedomorphic newts were more likely to be infected; ii) cysts were mostly located on the head and into the mouth; iii) the infection did not affect the body size of newts; iv) survival probabilities of infected and not infected newts from the same population did not differ, and it was similar to the survival of newts from the not-infected population. We conclude that, at least in the short term, the metacercariae of C. complanatum are not damaging for T. carnifex .
Sensitivity of mesoscale model urban boundary layer meteorology to the scale of urban representation

Abstract. Mesoscale modeling of the urban boundary layer requires careful parameterization of the surface due to its heterogeneous morphology. Model estimated meteorological quantities, including the surface energy budget and canopy layer variables, will respond accordingly to the scale of representation. This study examines the sensitivity of the surface energy balance, canopy layer and boundary layer meteorology to the scale of urban surface representation in a real urban area (Detroit-Windsor (USA-Canada)) during several dry, cloud-free summer periods. The model used is the Weather Research and Forecasting (WRF) model with its coupled single-layer urban canopy model. Some model verification is presented using measurements from the Border Air Quality and Meteorology Study (BAQS-Met) 2007 field campaign and additional sources. Case studies span from "neighborhood" (10 s ~308 m) to very coarse (120 s ~3.7 km) resolution. Small changes in scale can affect the classification of the surface, affecting both the local and grid-average meteorology. Results indicate high sensitivity in turbulent latent heat flux from the natural surface and sensible heat flux from the urban canopy. Small scale change is also shown to delay timing of a lake-breeze front passage and can affect the timing of local transition in static stability.
On the stark broadening of Ar VII spectral lines

Stark broadening parameters, full width at half maximum of s pectral line and shift, have been calculated for 3 spectral lines of Ar VII, for broadening by electron, proton, and He III impacts. For calculations, the semiclassical perturbation approach in the impact approximation has been used. The results are provided for temperatures from 20 000 K to 500 000 K and for an electron density of 10 17 cm -3 . Obtained results will be included in the STARK-B database which is also included in Virtual atomic and molecular data center (VAMDC).
