Impact factors of knowledge sharing intention of it employees in Vietnam – An integrated approach

In knowledge era, knowledge sharing has been becoming an essential issue to knowledge-based organizations, such as IT businesses. However, knowledge sharing among workers in IT organizations is not efficient in reality. Especially, in a developing country like Vietnam, there is a lack of research in this topic. Therefore, this research tries to identify and to measure the impact of those factors on knowledge sharing intention of employees in IT industry. Unlike previous studies, this research integrated factors of Theory of Planned Behavior (TPB) and other factors of organization environment and ICT to explore their impacts on knowledge sharing intention. Using Convenience sampling method, 257 valid samplings were collected from organizations in IT industry in HCMC. The scale was tested by Cronbach’s Alpha, EFA analysis methods. Based on regression analysis, the factor affecting on knowledge sharing intention of employees was sorted by descending order, including: affiliation and innovativeness in organization, attitude towards knowledge and subjective norms, perceived behavioral control. Besides, the knowledge sharing intention of employees is also indirectly affected by factors: anticipated reciprocal relationship and fairness in organization and support of ICT. The results of ANOVA analysis shows that there is a marked difference of knowledge sharing intention between managers and employees. Based on these results, some suggestions for facilitating knowledge sharing between employees in IT industry are proposed.
Occurrence of Salmonella in ruminants and camel meat in Maiduguri, Nigeria and their antibiotic resistant pattern

Objective: This study was conducted to determine the occurrence of Salmonella in various meat products (beef from cattle, chevon from goats, mutton from sheep and jaziir from camel), by screening the various selling points which includes; meat retailers in abattoir, markets and shops in Maiduguri and its environs. Materials and methods: A total of 120 samples of fresh meat from cattle, sheep, goats and camels sampled from ten meat retailers in abattoir, markets and shops in the Maiduguri metropolis, using simple random sampling technique. All samples were processed and examined according to standard bacteriological protocols. Results: Percentage occurrence of Salmonella species had the highest value of 15 (50.1%) from the market, found in sheep, while the lowest occurrence of Salmonella species was associated with 3(10.0%) in goats sampled from shop meat. Antibiotic susceptibility pattern of Salmonella species from cattle meat revealed high resistant to Erythromycin (52%). In sheep, the higher percentage of resistance occurred against Ampicillin (33.3%) and less resistant to Amoxicillin (4%) was obtained. The isolates from camel meat recorded 25% resistant against Ampicillin, Gentamycin and 12.5% to Streptomycin. A total of 28.4% of the isolates were resistant to Ampicillin, Gentamycin and 23.1% to Ofloxacin. Conclusion: The study has shown that Salmonella species are present in fresh meat sold in abattoir, retail markets and shops. We recommend strict hygienic measures in places where fresh meat are sold in Maiduguri metropolis, Nigeria to ensure consumers right to have safe food.
Interactive Predispositions

Many cases of gene‐environment interaction, or \documentclass{aastex} \usepackage{amsbsy} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{bm} \usepackage{mathrsfs} \usepackage{pifont} \usepackage{stmaryrd} \usepackage{textcomp} \usepackage{portland,xspace} \usepackage{amsmath,amsxtra} \usepackage[OT2,OT1]{fontenc} \newcommand\cyr{ \renewcommand\rmdefault{wncyr} \renewcommand\sfdefault{wncyss} \renewcommand\encodingdefault{OT2} \normalfont \selectfont} \DeclareTextFontCommand{\textcyr}{\cyr} \pagestyle{empty} \DeclareMathSizes{10}{9}{7}{6} \begin{document} \landscape $$\mathrm{G}\,\times \mathrm{E}\,$$ \end{document} , are misconstrued as evincing a genetic predisposition. I diagnose this misconstrual and then introduce a new concept—interactive predisposition—to correct for the mistake. I conclude by examining how recent debates over screening for individual predispositions are related to older debates about group differences between populations, drawing on the lessons of the latter to inform the former.
Neural gain control measured through cortical gamma oscillations is associated with individual variations in sensory sensitivity

Gamma oscillations facilitate information processing by shaping the excitatory input/output of neuronal populations, and their suppression by strong excitatory drive may stem from inhibitory-based gain control of network excitation. Individual variations in the gamma suppression may therefore reflect efficiency of gain control and subjective sensitivity to everyday sensory events. To test this prediction, we assessed the link between self-reported sensory sensitivity and changes in magneto-encephalographic gamma oscillations as a function of motion velocity of high-contrast visual gratings. The induced gamma oscillations increased in frequency and decreased in power with increasing stimulation intensity. As expected, weaker suppression of the gamma response correlated with sensory hypersensitivity. Robustness of this result was confirmed by its replication in the two samples: neurotypical subjects and people with autism, who had generally higher sensory sensitivity. We conclude that intensity-related suppression of gamma response is a promising biomarker of homeostatic control of the excitation-inhibition balance in the visual cortex.
Connecting the Sequence-Space of Bacterial Signaling Proteins to Phenotypes Using Coevolutionary Landscapes

Two-component signaling (TCS) is the primary means by which bacteria sense and respond to the environment. TCS involves two partner proteins working in tandem, which interact to perform cellular functions while limiting interactions with non-partners (i.e., “cross-talk”). We construct a Potts model for TCS that can quantitatively predict how mutating amino acid identities affect the interaction between TCS partners and non-partners. The parameters of this model are inferred directly from protein sequence data. This approach drastically reduces the computational complexity of exploring the sequence-space of TCS proteins. As a stringent test, we compare its predictions to a recent comprehensive mutational study, which characterized the functionality of 204 mutational variants of the PhoQ kinase in Escherichia coli. We find that our best predictions accurately reproduce the amino acid combinations found in experiment, which enable functional signaling with its partner PhoP. These predictions demonstrate the evolutionary pressure to preserve the interaction between TCS partners as well as prevent unwanted “crosstalk”. Further, we calculate the mutational change in the binding affinity between PhoQ and PhoP, providing an estimate to the amount of destabilization needed to disrupt TCS.
Genetic Differentiation of ARC Soybean [Glycine Max (L.) Merrill] Accessions Based on Agronomic and Nutritional Quality Traits

Soybean is one of the most important leguminous crops grown globally for food and feed. The study of genetic diversity is invaluable for efficient utilization, conservation and management of germplasm collections. The study aims at assessing genetic diversity present among the soybean genotypes using phenotypic markers. The restriction maximum likelihood revealed highly significant differences among the genotypes for eight quantitative traits. The principal component analysis revealed three most important PCs contributing 63.19%, 25.43% and 8.88% to the total variation of 97.5%, respectively. Seed yield was highly significant and highly correlated with seed number per plant, pod weight per plant, pod number per plant, and hundred seed weight but negatively correlated with seed number per pod. The hierarchical clustering revealed three major clusters with further sub-clusters. The accessions 2015/06/12, 69 S 10, PR 154-14, R 5-4-2 M, Hawkeye (USSR), and PR 145-2 were the most diverse. There were significant differences among the accessions based on nutritional quality traits such as oil, protein and stearic acid across the locations. The protein content varied from 29.1% to 35.6%, oil content varied from 10.6% to 20.7% whereas oleic acid and ash varied between 6.8% and 30.8%, and 4.3% and 8.2%, respectively. There was vast genetic diversity among the soybean genotypes. The presence of genetic diversity will aid breeders in selections and hybridization programmes for crop improvement.
Determining Force behind Value Premium: The Case of Financial Leverage and Operating Leverage

The determining force behind the value premium is the matter of debate among the researchers. Some are of the opinion that the financial distress risk determines value premium whereas other theorize that value premium is basically the compensation for operating leverage (investment activity risk). This research provides empirical evidence on this theoretical contradiction by investigating the relationships of financial leverage (FL) and operating leverage (OL) with stock returns, the book to market ratio (B/M), and systematic risk on non-financial sector firms trading at the Pakistan stock exchange (PSE). This research empirically finds significant and direct influence of operating leverage on stock returns, the book to market ratio, and systematic risk respectively. Overall findings provide support for the theoretical models which have a linked book to market effect with operating leverage. Thus, we conclude that investment activity risk seems to be the major factor that determines value premium.
Statistical Arbitrage with Uncertain Fat Tails

I develop a model of statistical arbitrage trading in an environment with “fat-tailed” information. If risk-neutral arbitrageurs are uncertain about the variance of fat-tail shocks and if they implement max-min robust optimization, they will choose to ignore a wide range of pricing errors. Although model risk hinders their willingness to trade, arbitrageurs can capture the most profitable opportunities because they follow a linear momentum strategy beyond the inaction zone. This is equivalent to a machine-learning algorithm called LASSO. Arbitrageurs can also amass market power due to conservative trading under this strategy. Their uncoordinated exercise of robust control facilitates tacit collusion, protecting their profits from being competed away even if their number goes to infinity. In an extended model where an insider strategically interacts with those arbitrageurs, the insider can induce them to trade too aggressively, giving herself a reversal trading opportunity. Doing so distorts price informativeness and threatens market stability.
Modeling Long Cycles

Recurrent boom-and-bust cycles are a salient feature of economic and finan- cial history. Cycles found in the data are stochastic, often highly persistent, and span substantial fractions of the sample size. We refer to such cycles as â€œlongâ€ . In this paper, we develop a novel approach to modeling cyclical behavior specifically designed to capture long cycles. We show that existing inferential procedures may produce misleading results in the presence of long cycles, and propose a new econometric procedure for the inference on the cycle length. Our procedure is asymptotically valid regardless of the cycle length. We apply our methodology to a set of macroeconomic and financial variables for the U.S. We find evidence of long stochastic cycles in the standard business cycle variables, as well as in credit and house prices. However, we rule out the presence of stochastic cycles in asset market data. Moreover, according to our result, financial cycles as characterized by credit and house prices tend to be twice as long as business cycles.
Robust Simulations

As scientists begin to study increasingly complex questions, many have turned to computer simulation to assist in their inquiry. This methodology has been challenged by both analytic modelers and experimentalists. A primary objection of analytic modelers is that simulations are simply too complicated to perform model verification. From the experimentalist perspective it is that there is no means to demonstrate the reality of simulation. The aim of this paper is to consider objections from both of these perspectives, and to argue that a proper understanding and application of robustness analysis is able to resolve them.

O mesofilo é dorsiventral, os feixes vasculares de pequeno porte são colaterais e ocorrem numerosas células contendo mucilagem e idioblastos com drusas de oxalato de cálcio. A nervura principal, em secção transversal, é plano-convexa, sendo percorrida por cerca de cinco feixes vasculares colaterais dispostos em arco aberto. SUMMARY. “Leaf Morpho-anatomical Analysis of Pereskia grandifolia Haw. , Cactaceae”. Pereskia grandifolia Haw. , commonly known as “ora-pro-nobis”, possesses leaves with high mucilage content, being employed as emollient in the traditional medicine and as food supplement. This work has analysed the leaf morpho-anatomy of the species, in order to supply information for its identification. The botanical material was fixed and prepared according to usual optical and scanning microtechniques. The leaves are simple, entire, ovate, glabrous and slightly succulent. The blade epidermis is uniseriate, coated by smooth and thin cuticle, and shows paracytic stomata on both surfaces. The mesophyll is dorsiventral, the minor bundles are collateral and many cells containing mucilage and idioblasts with calcium oxalate druses occur. The midrib, in transection, is plain-convex and has got about five collateral bundles distributed as an open arc.
Effect of Adjuvant Concentration and Carrier Volume on Large Crabgrass (Digitaria sanguinalis) Control with Fluazifop

Foliar activity of the butyl ester of fluazifop on large crabgrass was determined by varying the concentration of a petroleum-based oil concentrate and the carrier volume. Increasing the concentration of petroleum oil or reducing the carrier volume improved large crabgrass control. Under greenhouse conditions, both visible injury and plant dry weight reflected greater control with adjuvant concentrations increasing from 0.62 to 5.0% v/v. Similarly, reducing carrier volumes from 374 to 47 L/ha increased grass control. No significant interaction between carrier volume and adjuvant concentration suggests the effects of these two variables are independent of one another. For both variables, effects were greater with sublethal rates of fluazifop.
Identification and characterization of AJ18, a novel zinc finger transcription factor expressed during skeletal development

In response to osteo-inductive signals generated by the bone morphogenetic proteins (BMPs), undifferentiated mesenchymal stem cells c m differentiate into osteoblasts. However, the molecular mechanisms that coordinate and direct osteogenesis are largely unknown. Differential display was utilized to identifj a gene, provisionally named AJI8, whose expression is responsive to BMP-7 and up-regulated during osteoblastic differentiation in fetal rat calvarial cells (FRCCs), AJ18 encodes a novel protein comprishg a KrUppel-associated box (KRAB) domain, which is a well-characterized transcription repressor motif, and 11 successive C2H2 zinc hger motifs. Using a target detection assay, a consensus DNA-binding site with the sequence 5'-CCACA-3' was revealed, This sequence is present in the enhancer for Rum2 (OSE2, osteoblast-specific element 2; 5'-ACCACA-3'), a rnaster gene for osteogenesis. By using a transient transfection assay MI8 expression was found to abrogate the transactivation activity of Runx2 in a dose-dependent marner. To study the regdation of AJI8 gene expression, a rat genomic Lbrary was screened to obtain the 5'-flanking region of MI&. Mapping of the transcription start site showed that the AJI8 gene contains an unusually long 2.3 kb 5'-untranslated region (5'-UTR) with potential for strong secondary structure. Chimeric consiructs encompassing the immediate prornoter region (77 to t177) revealed mng transcriptional activity when ligated to a luciferase reporter gene in transient transfection assays. Addition of -2 kb of upstream sequence did not increase this activity. Comparison of mouse and rat AJ18 promoters however r e v d d high sequence identity that included several responsive eIements for proteins such as Runx2, NFicB, Smads, Spl, and Ets 1. The expression of M l 8 mRNA and proteh at various stages of mouse development revealed high levels in brain, kidney, and mineraiized tissues during embryonic development. In developing endochondral bone, M l 8 staining was strong in proliferating and pre-hypertrophie chondrocytes, and osteoblasts, with low or no staining in hypertrophie chondrocytes. NucIear staining was also observed in differentiating celIs that form the mineraiized tissues of teeth. Notably, the expression of AJ18 was similaito the expression of BMP-7 consistent with its perceived role as a transcriptional factor that regulates developmental processes downstream of BMP-7. These studies, therefore, have identified the fmt KRAB/C2H2 zinc finger gene to be implicated in skeletal development, and have charactenzed the first promoter sequence for a gene belonging to the large KRABKzH2 zinc figer family.
Employee Mobility and Innovation

This study aims to investigate the effect of employee mobility constraint through inevitable disclosure doctrine (IDD) adoption by U.S. state courts on firms' innovation. IDD adoption serves as an exogenous shock on the labour market and industry competition from which this study expects the negative effect on firms' innovation comes. This study uses U.S. firms and measures innovation using R&D expenditure and patent registration and citation. This study finds that employee career constraints through IDD adoption reduces industry competition. The deteriorating effect of IDD enactment on innovation is not only for the initial adoption period but also for at least one year ahead. The negative impact of employee mobility constraint is due to the decrease in market competition. This research suggests that the relaxation of market monitoring on managers will decrease the performance of the firm.

Catalog of Chinook Salmon Spawning Areas in Yukon River Basin in Canada and United States

Abstract Chinook Salmon Oncorhynchus tshawytscha return to the Yukon River in northwestern North America each summer, migrating to spawning destinations from the lower river to more than 3,000 km upstream. These returns support numerous fisheries throughout the basin. Despite a long history of fisheries research and management, there is no comprehensive account of Chinook Salmon spawning areas in the basin. To address this issue, we cataloged, summarized, and mapped the known spawning areas of Yukon River Chinook Salmon by using a variety of sources including published articles, gray literature, and information archived in agency databases. Most of our sources were published within the past 30 y, but some refer to observations that were recorded as long ago as the late 1800s. We classified spawning areas as major or minor producers with three indicators of abundance: 1) quantitative estimates of escapement (major producer if ≥500 fish, minor producer if <500 fish), 2) radiotelemetry-based proportions of a.
Integrative analysis of microRNA and mRNA expression profiles in osteosarcoma cell lines

The aim of this study was to provide a comprehensive analysis of the role microRNA deregulation might play in osteosarcoma pathogenesis. Osteosarcoma cell lines were analyzed for genome wide microRNA and mRNA expression. Additionally the cell lines were characterized phenotypically using in vitro cell assays. By this means, deregulated microRNA and their potential target genes significantly correlating with the osteosarcoma cell lines’ potential to proliferate, migrate and invade were found. Moreover, microRNA and mRNA differentially expressed in osteosarcoma versus progenitor cell lines (using human osteoblasts and mesenchymal stem cell lines as references) have been identified.
Occasional photographic records of butterflies (Lepidoptera, Papilionoidea) in Cambodia: 3, Pursat, Siem Reap, Preah Vihear and Stung Treng Provinces in western, north-western and northern Cambodia

The butterfly (Papilionoidea) fauna of Cambodia is very rich but too insufficiently studied. Results are presented of occasional photographic records of butterflies (Lepidoptera, Papilionoidea) made in 2016–2019 (some also in 2006) along with studies on the Odonata fauna in 67 localities of western and northern provinces of Cambodia: Pursat, Siem Reap, Preah Vihear and Stung Treng. This paper completes the two previous communications of this series devoted to the south-western and eastern provinces of this country. In total, 162 identified and 13 provisionally identified species are listed; 22 species (Miletus ancon, Arhopala agrata, A. alesia, A. allata, A. ammonides, A. atrax, A. aurelia, A. moolaiana, A. silhetensis, Drupadia theda, Anthene licates, Prosotas aluta, Danaus chrysippus, Cirrochroa surya, Doleschallia bisaltide, Athyma ranga, Euthalia recta, Burara oedipodea, Hasora chromus, Pseudocoladenia dan, Koruthalaios sindu, Parnara ganga) are for the first time reported in literature for Cambodia. These and some problematic species are illustrated. Some misidentifications in the two first communications of the series are made; due to reidentification Arhopala camdana and Borbo cinnara are for the first time reported for Cambodia in literature.
