The Mediating Effect of Organizational Commitment on Leadership Type and Job Performance

In order to active the education industry and make a contribution for the higher education field, private higher education becomes a backbone force in Chinese society. Based on the report of Ministry of Education in 2017 mentioned that the biggest problem with private higher education is that the weak and unstable academic staffs which lead to low job performance. In addition to policies and management, how to further improve the quality and performance of academicians is also an essential issue eager to be solved in private education institutions. Therefore, how to construct qualified personnel is one of the fundamental problems in the survival and development of private colleges and universities. The performance and quality of the academic staffs largely determines the quality of private colleges and universities. Leadership style was regarded as an importance role affect organizational commitment and organizational performance. This study intends to find out the mediating effect of organizational commitment on the relationship between leadership style and job performance by using the survey data from academicians of top ten Chinese private universities.
Ultrastructural Observations on Spermatogenesis within Testes in Haemaphysalis longicornis (Acari: Ixodidae)

A rnale tick gives elongated spermatids to a female, that is, spermatogenesis within testes completes itself until elongated spermatids. And then elongated spermatids develop into mature sperms after they enter into the female genital tract via the spermatophore. In the present study, ultrastructural observations of spermatogenic cells were made at each stage of spermatogenesis in male Haemphysalis longicornis. Spermatogenic cells from spermatogonia to primary spermatocytes at the middle of their great growth phase were found in testes of unfed males. Subsequently, testes of H. longicomis are developed by feeding at their adult stage. The testes, or spermatogenic cells, were developed gradually until the 5-day feeding period was complete (the complete feeding stage). Spermatogenic cells at all stages from spermatogonia to elongated spermatids were contained in the testes of completely fed males. Spermatogenic cells were packed in cysts. Elongated spermatids which had been completed at the posterior ends of testes were made spermiation with the breakdown of the cyst cells. The spermatids were carried out of the testes through the central lumen. The cyst cells formed the lumen, and had some microvilli on their free surface.
EFFECT ON MILK PRODUCTION AND CALF PERFORMANCE OF MILKING CROSS BRED EUROPEAN/ZEBU CATTLE IN THE ABSENCE OR PRESENCE OF THE CALF, AND OF REARING THEIR CALVES ARTIFICIALLY

Five hundred and thirty nine lactations of crossbred European/Zebu conga, were analysed to study the effect of milking, with or without the presence of the calf, on the performance of cows and calves. The study was carried out in Tabasco State, in conditions of the humid tropics, the feeding system being grazing with minimum supplementation when pasture growth was in short supply. Approximately 40% of the cows that were milked without the calf being present had short lactations and this reduced the amount of saleable milk to an average of 621 litres/lactation of 197 d. Cows that appeared to give acceptable lactation length. and production, without the presence of the calf in their first lactation, showed a significant tendency to reduce their level of miIk production and to become dry prematurely in subsequent lactations under the same system of management. The cows that became dry prematurely when milked without the presence of the calf gave normal yields (968 litres in 268 d) in their subsequent lactation, when they were milked with the presence of the calf and with the restricted suckling after milking. The restricted suckling system was considered to be the most appropriate since over a total of 230 lactations the average yield of saleable milk was 1120 litres in 262 d. There was also a reduced incidence of subclinical mastitis in the cows that were milked with their calves. A low rate of growth (277 g/d) and a high mortality were observed when the calves were reared artificially. These problems were reduced significantly when the calves were reared by restricted suckling, as growth rate increased to an average of 464 g/d and mortality wee reduced to 6%.
Partitioning of Ca and Al between forsterite and silicate melt in dynamic systems with implications for the origin of Ca, Al‐rich forsterites in primitive meteorites

Abstract— We report the results of dynamic crystallization experiments that were specifically designed to study the dependence of Ca and Al partitioning between forsterite and melt in rapidly cooling Caand Al‐rich melts. The partitioning of Ca between olivine and silicate melt is found to be independent of the cooling rate within the range of 1.5 to 1000°C/hr and at CaO contents of up to 25 wt%. Within analytical uncertainty, our data plot on the equilibrium partitioning curve obtained by Libourel (1999). The partitioning behavior of Al at high cooling rates is more complex. Aluminum is much more heterogenously distributed in the olivine and the co‐existing melt than Ca. But, no systematic trend of Al partition coefficient with cooling rate is observed. We apply the results of the experiments to the formation of meteoritic forsterites with relatively high contents of Ca and Al. Although these forsterites are found frequently inside chondrules, the Ca contents of their host chondrules are far too low to crystallize these high Ca‐forsterites. This is also true for very rapid cooling of chondrule melts. The parental melt of these forsterites requires CaO contents above 20 wt%.
The Adoption of Temperate Selected Sesame Accessions in the Tropics: Selected for Japan and Grown in Ghana

Sesame is an oilseed crop which can be grown on marginal lands. Selection of stable sesame cultivars that can adapt to local environmental conditions can be a very important food security strategy. A set of 21 high yielding sesame accessions that have been selected for a temperate region were grown in the transitional zone of Ghana during the major season of 2014. The seeds were sown after the first rain in the year in a completely randomized design, with three replications. The objective was to evaluate the effect of the contrasting environment on sesame phenology and to select cultivars with yield potential that can be accepted into local farming systems in the new environment. Morphological, physiological and agronomic traits, leading to yield were recorded in this study. Number of capsules per plant had the strongest association (72%) with seed yield. Five accessions showed a combination of early maturity 20 g per plant) and good harvest index (0.29). Based on their mean performance these cultivars have been selected as promising exotic cultivars for the new locality.
Commercial Swim Programs With Dwarf Minke Whales On The Northern Great Barrier Reef, Australia: Some Characteristics Of The Encounters With Management Implications

Commercial swim programs with the dwarf minke whale Balaenoptera ? acutorostrata occur seasonally (primarily June - July) within the Cairns and Far Northern sections of the Great Barrier Reef (GBR) Marine Park. Observations of whale-swimmer interactions over five seasons indicate that initiation and maintenance of contact with vessel and swimmers is largely voluntary and thus the swim programs can comply with the general principle that the whales control the initiation and nature of interactions. Preliminary data on within-season (13 whales in 1999) and between year (four whales from 1999 in 2000, 2001) re-sightings within the study area suggest that any impacts from swim programs may affect a particular subset of the population. The extent of possible cumulative effects can be assessed by continuation of the existing photo and video-ID program. No signs of aggression have been documented but some behaviour (bubble blasts, jaw gape) could be considered as threat display. More detailed analysis of behaviour is necessary to monitor such behaviour. A risk analysis is given for aspects of the interactions, with suggested research to monitor such risks.
SUBGRID-SCALE MODELING IN LARGE-EDDY SIMULATION AND ITS APPLICATION TO FLOW ABOUT YAWED CYLINDER AND CAVITY FLOWS

In this computation, Smagorinsky’s eddy viscosity model combined with a truncated deductive model is used to represent the SGS stress fields in quadrilateral/hexahedral structured/unstructured grid system. The truncated deductive model considers the eddies immediately below the filter size, ∆, which presumably lies within the inertial range, but not those near Kolmogorov scale, η, such that dissipation is not properly accounted for. Therefore it is assumed in this study that the Smagorinsky model describes the dissipation correctly, and the truncated deductive model ensures a smooth cascade process. To show the applicability of the proposed SGS model to the structured/unstructured grid system, two cases of the flow about a yawed cylinder and a cavity flow were numerically tested and compared with experimental data. The present results of the yawed cylinder were produced at a Reynolds number of 1.3×10 in the sub-critical range. As a second example of validating the code, three configurations of cavity (L/D=1.5, 2.0, 10.0) were used to simulate quasi-periodic flow patterns at a Reynolds number of 1.0×10. The sound generated from turbulent flows around the yawed cylinder and in the cavity was also computed using Lighthill’s acoustic analogy. The LES results are compared to experimental data in terms of local characteristics such as base pressure coefficients, wall pressure and far-field noise spectra, which were measured in an acoustic wind-tunnel facility.

ALMA CO and VLT/SINFONI H 2 observations of the Antennae overlap region: mass and energy dissipation

We present an analysis of super-giant molecular complexes (SGMCs) in the overlap region of the Antennae galaxy merger, based on ALMA CO(3-2) interferometry and VLT/SINFONI imaging spectroscopy of H2 1-0 S(1) at angular resolutions of 0.9" and 0.7", respectively. All but one SGMC have multiple velocity components offset from each other by up to 150 km/s. H2 line emission is found in all SGMCs and the kinematics of H2 and CO are well matched. H2/CO line ratios vary by up to a factor of 10 among SGMCs and different velocity components of the same SGMCs. We also identify the CO counterpart of a bright, compact source of near-IR H2 line emission, which shows no Brgamma, and was first identified with SINFONI. This source has the highest H2/CO line ratio, and coincides with the steepest CO velocity gradient of the entire overlap region. With a size of 50 pc and a virial mass of a few 10^7 Msun it is perhaps a pre-cluster cloud that has not yet formed significant numbers of massive stars. We present observational evidence that the H2 emission is powered by shocks, and demonstrate how the H2 1-0 S(1) and the CO(3-2) lines can be used as tracers of energy dissipation and gas mass, respectively. The variations in the H2/CO line ratio may indicate that the SGMCs are dissipating their turbulent kinetic energy at different rates. The compact source could represent a short (~ 1 Myr) evolutionary stage in the early formation of super-star clusters.
Financial Inclusion, Growth and Inequality: A Model Application to Colombia

Financial inclusion has been one of the key pillars of Colombia’s development strategy for a number of years. Financial inclusion policies have aimed at channeling microcredit to poor, spreading formal banking system usage, fostering electronic payment acceptance, and making financial services more affordable. Using simulations from a general equilibrium model it is possible to identify the most binding financial sector frictions that preclude financial inclusion of enterprises, and study the effects on growth and inequality of efforts to remove these frictions. The study finds that lowering contraints on collateral promises higher growth while inequality is better tackled through measures that lower the financial participation cost.
Trading in the Presence of Short-Lived Private Information: Evidence from Analyst Recommendation Changes

We use a proprietary data set to test the implications of several asymmetric information models on how short-lived private information affects trading strategies and liquidity provision. Our identification rests on information acquisition before analyst recommendations are publicly announced. We provide the first empirical evidence supporting theoretical predictions that early-informed traders “sell the news” after “buying the rumor. ” Further, we find distinct profit-taking patterns across different classes of institutions. Uninformed institutions, but not individuals, emerge as de facto liquidity providers to better-informed institutions. Placebo tests confirm that these trading patterns are unique to situations in which some investors have a short-lived informational advantage.
Middle Jurassic vegetation dynamics based on quantitative analysis of spore/pollen assemblages from the Ravenscar Group, North Yorkshire, UK

Quantitative analysis of the distribution of dispersed spores and pollen (sporomorphs) has been used to assess temporal floral variation through the Middle Jurassic Ravenscar Group (Aalenian–Bathonian), North Yorkshire, UK. Aalenian, Bajocian and Bathonian strata possess relatively distinct sporomorph and palynofacies assemblages, which potentially reflect a dynamic history regarding the nature of parent vegetation. Specifically, Aalenian palynofloras are composed of a heterogeneous mixture of conifers, ferns, simple monosulcate pollen producers, sphenophytes and Caytoniales; Bajocian palynofloras are codominated by conifers and ferns; and Bathonian palynofloras are highly rich and contain assemblages of abundant ferns, conifers, lycophytes, pteridosperms/conifers and Caytoniales. Individual‐ and sample‐based rarefaction demonstrates that Bathonian samples are richer than Aalenian and Bajocian samples. Temporal variations in assemblages are a result of long‐term depositional and possible climatic fluctuations through the Middle Jurassic. Ordinations of sporomorph data using non‐metric multidimensional scaling (NMDS) demonstrate that short‐term variations between samples are largely governed by taphonomic biases as a result of slight changes in depositional processes, which give rise to highly variable catchment areas that supply deposits with sporomorphs. Long‐term compositional changes are apparent in sporomorph assemblages regardless of lithology/local depositional environments, suggesting that long‐term variations are more substantial than short‐term variations and potentially include genuine regional temporal changes in parent vegetation. Relating sporomorph assemblages with their respective depositional environments and relative catchment area sizes using lithological and palynofacies information suggests that the basin interior was occupied by mostly low‐standing species and extrabasinal vegetation was dominated by coniferous taxa. Comparisons of the dispersed sporomorph and plant megafossil records indicate that both fossil assemblages reflect different aspects of the palaeoflora due to a multitude of taphonomic and ecological biases. Such biases include variation in sporomorph production levels, depositional environment and differential sporomorph and parent plant durability.
LARGE-SCALED SIMULATION ON THE COHERENT VORTEX EVOLUTION OF A JET IN A CROSS-FLOW BASED ON LATTICE BOLTZMANN METHOD

Large eddy simulation (LES) is performed on a jet issued normally into a cross-flow using lattice Boltzmann method (LBM) and multiple graphic processing units (multi-GPUs) to study the flow characteristics of jets in cross-flow (JICF). The simulation with 8 1.50´10 grids is fulfilled with 6 K20M GPUs. With large-scaled simulation, the secondary and tertiary vortices are captured. The features of the secondary vortices and the tertiary vortices reveal that they have a great impact on the mixing between jet flow and cross-flow. The qualitative and quantitative results also indicate that the evolution mechanism of vortices is not constant, but varies with different situations. The hairpin vortex under attached jet regime originates from the boundary layer vortex of cross-flow. While, the origin of hairpin vortex in detached jet is the jet shear-layer vortex. The mean velocities imply the good ability of LBM to simulate JICF and the large loss of jet momentum in detached jet caused by the strong penetration. Besides, in our computation, a high computational performance of 1083.5 MLUPS is achieved.
Union presence, employee relations and high performance work practices

Purpose – The purpose of this paper is to investigate the relationship between unions, employee relations and the adoption of high performance work practices (HPWP). Design/methodology/approach – This study uses survey data collected from the senior members of the human resource management (HRM) function in 189 large Australian organisations. Findings – It was found that unions, when coupled with good employee relations, facilitate the adoption of HPWP and consequently have a positive impact on organisational competitiveness, contradicting the simplistic notion that unions are “bad for business”. Research limitations/implications – This study used cross‐sectional survey data from HRM managers, who while being the best single source of information, may have distorted their responses. Further research is required to confirm these results using several data sources collected from a larger sample over more than one time period. Practical implications – This research has implications for Government and organisation approaches to union presence and management in organisations. Social implications – This research contributes to HRM and organisational competitiveness, which has implications for GDP. Originality/value – This paper contributes to the debate on whether the individual and direct voice provided by HPWP is a substitute for union collective voice, with the associated implication that unions are unnecessary and even destructive to organisation competitive advantage.
Search for aluminium monoxide in the winds of oxygen-rich AGB stars

Aluminium monoxide (AlO) is likely efficiently depleted from the gas around oxygen-rich evolved stars to form alumina (Al2O3) clusters and dust seeds. The presence of AlO gas in the extended atmospheres of evolved stars has been derived from optical spectroscopy. More recently, AlO gas was also detected at long wavelengths around the supergiant VY CMa and the oxygen-rich asymptotic giant branch star o Cet (Mira A). The central role aluminium might play in dust formation and wind driving, in combination with these first detections of AlO at long wavelengths, shows the need for a wider search for this molecule in the winds of evolved stars. Aims. The detection at long wavelengths of emission in rotational transitions of AlO towards asymptotic giant branch stars can help constrain the presence and location of AlO gas in the outflows and ultimately also the efficiency of the depletion process. Methods. In search of AlO, we mined data obtained with APEX, the IRAM 30 m telescope, Herschel/HIFI, SMA, and ALMA, which were primarily aimed at studying other species around asymptotic giant branch stars. We report here on observations of AlO towards a sample of eight oxygen-rich asymptotic giant branch stars in different rotational transitions, up to seven for some stars. Results. We present definite detections of one rotational transition of AlO for o Cet and R Aqr, and tentative detections of one transition for R Dor and o Cet and two transitions for IK Tau and W Hya. The presented spectra of WX Psc, R Cas, and TX Cam show no signature of AlO. For o Cet, R Aqr, and IK Tau, we find that the AlO (N = 9-8) emission likely traces the inner parts of the wind, out to only a few tens of AU, where the gas has not yet been accelerated to its terminal velocity. This is in agreement with recently published results from a detailed study on o Cet. Conclusions. The conclusive detections of AlO emission in the case of o Cet and R Aqr confirm the presence of AlO in the gas phase in outflows of asymptotic giant branch stars. The tentative detections further support this. Since most of the observations presented in this study were obtained with stronger emission from other species than AlO in mind, observations with higher sensitivity in combination with high angular resolution will improve our understanding of the presence and behaviour of AlO. From the current data sets we cannot firmly conclude whether there is a direct correlation between the wind properties and the detection rate of AlO emission. We hope that this study can serve as a stimulus to perform sample studies in search of AlO in oxygen-rich outflows.
NUMERICAL STUDY OF DISPERSION AND NONLINEARITY EFFECTS ON TSUNAMI PROPAGATION

Numerical study of dispersion effect for tsunami propagation for the case of Indian Ocean Tsunami has been carried out using three model equations: Linear shallow water (LSW) equations, Nonlinear shallow water (NLSW) equations, and Weakly-Nonlinear Bossuineq-type (WNB) equations. Model simulation results are compared each other and against observations data. General features of tsunami wave patterns are agree very well using the three models but the WNB model produced development in time of tsunami front face which caused by the dispersion effect. Two dimensional wave pattern and spatial profile of sea surface are discussed to study the dispersion effect.
