Strike a subtle Balance between Being Too Lenient and Too Strict: the IT Enabled Ambidexterity of Governance Conversion

Firms in China and in Asian-pacific countries normally encounter a governance paradox of being too lenient via relational-based governance or being too strict via contractual-based governance under uncertainty. While both governance mechanisms have been extensively studied separately under inter-firm governance contexts, though some studies showing complementary and substituted as the interactions between these two, few, if any studies focus on the further conversional process in details of how these two make complement or substitute especially in the digital age. In this study, from the lens of ambidexterity theory, we employ an exploratory case study methodology and attempt to understand its interaction process in a Chinese firm. We submit there is a conversion via information technology between contractual-based governance and relational-based governance and IT acts as an intermediary to support organization ambidexterity thus enabling governance conversion. Precisely, IT can bring flexibility and support general trust exploration as well as system-based change exploitation thus enabling contractual-based governance to convert into relational-based governance. Besides, IT can assess and standardize relationships via providing process and rules, and support knowledge-based trust exploitation as well as system-based process exploration thus enabling relational-based governance to convert into contractual-based governance. Our study inspires firms to response uncertainty and keeping inter-firm cooperation by IT-enabled governance conversion.
Microleakage of Three Types of Glass Ionomer Cement Restorations: Effect of CPP-ACP Paste Tooth Pretreatment

Statement of the Problem Casein phosphopeptide–amorphous calcium phosphate (CPP-ACP) increases the mineral content of tooth structure. This may enhance the chemical bonding of glass ionomer cements (GIC) and marginal sealing of their restorations. Purpose The aim of this study was to evaluate the effect of CPP-ACP paste pretreatment on the microleakage of three types of GIC. Materials and Method In this study, 72 Class V cavities were prepared on the buccal and lingual surfaces of molars with occlusal margins in enamel and gingival margins in root. The cavities were divided into 6 groups. Cavities in group 1 and 2 were restored with Fuji II, group 3 and 4 with Fuji II LC, and group 5 and 6 with Ketac N100 with respect to the manufacturers’ instructions. In groups 2, 4 and 6, CPP-ACP containing paste (MI paste) was placed into the cavities for 3 minutes before being filled with GIC. The teeth were thermocycled, stained with dye, sectioned, and scored for microleakage under stereomicroscope. Kruskall-Wallis and Chi-Square tests were used to analyze the data. Result There were no statistically significant differences between the control and the CPP-ACP pretreatment groups in enamel and dentin margins. In pairwise comparisons, there were no significant differences between the control and the experimental groups in enamel margin, and in dentin margins of G1 and 2, G5 and 6; however, a significant differences was detected in dentin margins between G3 and 4 (p= 0.041). Conclusion CPP-ACP paste pretreatment did not affect the microleakage of Fuji II and Ketac N100 in enamel or dentin, but decreased the microleakage in dentine margins of Fuji II LC when cavity conditioner was applied before surface treatment.
Attitudes of higher education faculty toward distance education: A national survey

Abstract Although distance education is growing in importance in the United States, little research has focused on the attitudes of American college and university teachers toward college‐level distance education and toward the use of specific media in distance education provision. The attitudes of both participating and nonparticipating faculty toward distance education need further examination, since teaching innovations cannot succeed without their support. This study examines the receptivity to college‐credit distance education of faculty members in two‐ and four‐year higher education institutions. The research questions focused on general receptivity to distance education, the relationship between professional characteristics and attitude toward distance education, the connection between previous distance education experiences/ familiarity and receptivity, and on attitudes toward different distance education media and methods.
A Linear Programming Formulation for Global Inference in Natural Language Tasks

Abstract : Given a collection of discrete random variables representing outcomes of learned local predictors in natural language. e.g. named entities and relations. we seek an optimal global assignment to the variables in the presence of general (non-sequential) constraints. Examples of these constraints include the type of arguments a relation can take, and the mutual activity of different relations. etc. We develop a linear programing formulation for this problem and evaluate it in the context of simultaneously learning named entities and relations. Our approach allows us to efficiently incorporate domain and task specific constraints at decision time, resulting in significant improvements in the accuracy and the "human-like" quality of the inferences.
Morphological Analysis of the Connective Tissue Reaction in Linear Hypertrophic Scars Treated with Intralesional Steroid or Silicone-Gel Sheeting. A Light and Electron Microscopic Study

The linear hypertrophic scar has become the most common type of pathologic scarring. Silicone-gel sheeting is the first line therapy while intralesional steroid is the second. A. light and electron microscopic analysis was carried out to reveal differences in tissue reaction following the two different treatments. Two groups of 12 patients each were treated for 4 months. For the first group, diluted Triamcinolone acetonide was injected until an inactive state was achieved. The other group of patients was treated with silicone-gel sheeting. The scars were examined every two weeks and their appearance documented. After reaching the expected therapeutic response, inactive scars were removed. The excised scars were evaluated through light microscopic histopathology and electron microscopy. The light and electron microscopic observations revealed marked differences following treatments. The activity of fibroblasts and the numbers of collagen fibers forming bundles decreased and the orientation of the collagen fibers was more variable in the treated scars. The amount of elastic fibers increased after both steroid and silicone-gel sheeting treatment. Vascularization was also slightly changed, with more capillaries and fewer pre-capillary arteries detected in the treated scars. Both treatments resulted in the same decrease in score but steroid treatment was more rapid in onset. We suggest that the two different treatments work through different mechanisms, although the final functional outcome is similar.
Work attitudes, strain and mental health of employed mothers in Bangladesh

Abstract This study was an attempt to measure domestic and employment role attitudes, strain and mental health of employed mothers. Data were collected from 105 employed mothers engaged in part- and full-time employment in banks and educational institutions. The measuring instruments used were: the Home and Employment Role Scale (HER) and the General Health Questionnaire (GHQ). The results showed that employed mothers with negative home and employment role attitudes suffer from a greater degree of strain man those with positive home and employment role attitudes. It was also found that negative home role attitudes generate more strain than negative employment role attitudes. The degree of strain of the employed mothers has been found to vary with the duration of work and time of commencement of their work shift. The employed mothers with dependent children suffer from more strain than those with grown-up children. A significant negative correlation has been found between strain and mental health. The resu.
Implicating Culicoides Biting Midges as Vectors of Schmallenberg Virus Using Semi-Quantitative RT-PCR

Background The recent unprecedented emergence of arboviruses transmitted by Culicoides biting midges in northern Europe has necessitated the development of techniques to differentiate competent vector species. At present these techniques are entirely reliant upon interpretation of semi-quantitative RT-PCR (sqPCR) data in the form of Cq values used to infer the presence of viral RNA in samples. Methodology/Principal Findings This study investigates the advantages and limitations of sqPCR in this role by comparing infection and dissemination rates of Schmallenberg virus (SBV) in two colony lines of Culicoides. Through the use of these behaviorally malleable lines we provide tools for demarcating arbovirus infection and dissemination rates in Culicoides which to date have prevented clear implication of primary vector species in northern Europe. The study demonstrates biological transmission of SBV in an arthropod vector, supporting the conclusions from field-caught Culicoides and provides a general framework for future assessment of vector competence of Culicoides for arboviruses using sqPCR. Conclusions/Significance When adopting novel diagnostic technologies, correctly implicating vectors of arboviral pathogens requires a coherent laboratory framework to fully understand the implications of results produced in the field. This study illustrates these difficulties and provides a full examination of sqPCR in this role for the Culicoides-arbovirus system.
Propensity, Social Ties, Friend Behavior, and Heavy Drinking Among College Students

The current research explores self-control, early-onset alcohol propensity, and social ties as they relate to heavy drinking on a college campus. The study draws on a survey of alcohol-related attitudes and behaviors administered to a cluster sample of 149 residential students (M age = 19.9; 51% female) at a medium-sized Midwestern university. A series of ordinary least squares regressions were conducted to explore independent and interactive effects of propensity and social ties on drinking. Propensity and antisocial ties consistently and independently predicted measures of heavy drinking and related consequences. Prosocial ties were less consistent, though they were associated with alcohol-related consequences. Propensity amplified the effects of antisocial ties on drinking and related consequences. Early-onset drinking and low self-control represented unique indicators of propensity for heavy drinking behavior in college. The strongest, most consistent finding across all models was the positive association between close friend substance behavior and participant drinking outcomes. This research indicates that although propensity (i.e., low self-control and early drinking behavior) may put individuals at risk of heavy drinking, these effects can be conditioned by dynamic social ties and thus prevention efforts should focus on these ties. Specifically, prevention campaigns and future research should target “students and their friends” as heavy drinking appears to be heavily influenced by close friendships and perceived norms.
Oocyte-specific expression of mouse Zp-2: developmental regulation of the zona pellucida genes

The zona pellucida surrounds all mammalian oocytes and plays a vital role at fertilization and in early development. The genes that code for two of the mouse zona proteins (ZP2 and ZP3) represent a developmentally regulated set of genes whose expression serves as markers of mouse oocyte growth and differentiation. We previously characterized the single-copy Zp-3 gene and showed that its expression is oocyte specific and restricted to a narrow window of oocyte development. We now define the Zp-2 gene transcript and show that it is coordinately expressed with Zp-3 only during the 2-week growth phase of oogenesis that occurs prior to ovulation. Like Zp-3, the expression of Zp-2 is restricted to oocytes, and, although not detectable in resting oocytes, both ZP2 and ZP3 transcripts accumulate to become very abundant messengers in 50-microns-diameter oocytes. Ovulated eggs contain ZP2 and ZP3 transcripts which are 200 nucleotides shorter than those found in growing oocytes and have an abundance of less than 5% of the peak levels. In an attempt to understand the molecular details associated with the developmentally regulated, tissue-specific gene expression of the zona genes, the Zp-2 genetic locus has been characterized and its 5' flanking sequences have been compared with those of Zp-3. Both genes contain three short (8- to 12-base-pair) DNA sequences of 80 to 88% identity located within 250 base pairs of their transcription start sites.
Psychological Determinants of Heart Failure Self-Care: Systematic Review and Meta-Analysis

Objective Psychological distress has been associated with poor outcomes in patients with chronic heart failure (HF), which is assumed to be partly due to poor HF self-care behavior. This systematic review and meta-analysis describes the current evidence concerning psychological determinants of self-care in patients with chronic HF. Methods Eligible studies were systematically identified by searching electronic databases PubMed, PsycINFO, and the Conference Proceedings Citation Index (Web of Science) for relevant literature (1980–October 17, 2014). Study quality was assessed according to the level of risk of bias. Quantitative data were pooled using random-effects models. Results Sixty-five studies were identified for inclusion that varied considerably with respect to sample and study characteristics. Risk of bias was high in the reviewed studies and most problematic with regard to selection bias (67%). Depression (r = −0.19, p < .001), self-efficacy (r = 0.37, p < .001), and mental well-being (r = 0.14, p = .030) were significantly associated with self-reported self-care. Anxiety was not significantly associated with either self-reported (r = −0.18, p = .24) or objective self-care (r = −0.04, p = .79), neither was depression associated with objectively measured medication adherence (r = −0.05, p = .44). Conclusions Psychological factors (depression, self-efficacy, and mental well-being) were associated with specific self-care facets in patients with chronic HF. These associations were predominantly observed with self-reported indices of self-care and not objective indices. Methodological heterogeneity and limitations preclude definite conclusions about the association between psychological factors and self-care and should be addressed in future research.
DSM IV, culture and child psychiatry.

OBJECTIVE The expanding cultural diversity of children and families with mental health needs raises questions about the cultural appropriateness of diagnostic classifications like the DSM IV. This paper briefly surveys the literature on culture and DSM-IV in child psychiatry, presenting ADHD as an example of the relationship between diagnostic categories and cultural issues, and illustrating some of the clinical dilemmas of differential diagnosis in a migration context. METHOD A literature review was performed and analysed, and a case vignette was constructed to illustrate key points. RESULTS The literature does not provide a definite answer about the DSM IV cultural validity in child psychiatry. On the one hand it suggests that all diagnostic categories may be found universally. On the other, variations in prevalence rates support the hypothesis of a role for social and cultural factors in the diagnostic process. The clinical formulation may be a useful tool to address the validity issue by modulating the process of diagnosis with a cultural understanding of the symptoms, the patient-therapist alliance and the appropriateness of treatment recommendations. CONCLUSION Although the DSM IV diagnostic categories may be found cross culturally, clinicians need to be aware of how culture may influence the diagnostic process in child psychiatry.
A shape-based layout descriptor for classifying spatial relationships in handwritten math

We consider the difficult problem of classifying spatial relationships between symbols and subexpressions in handwritten mathematical expressions. We first improve existing geometric features based on bounding boxes and center points, normalizing them using the distance between the centers of the two symbols or subexpressions in question. We then propose a novel feature set for layout classification, using polar histograms computed over points in handwritten strokes. A series of experiments are presented in which a Support Vector Machine is used with these new features to classify spatial relationships of five types in the MathBrush corpus (horizontal, superscript, subscript, below, and inside (e.g. in a square root)). The normalized geometric features provide an improvement over previously published results, while the shape-based features provide a natural representation with results comparable to those for the geometric features. Combining the features produced a very small improvement in accuracy.
The Impact of Team Atmosphere on Knowledge Outcomes in Self-managed Teams

This study defines the construct of team atmosphere and provides a framework within which causes and consequences of team atmosphere in knowledge transfer and creation can be empirically investigated. Data were collected using a survey of 363 individuals of 12 companies who worked in self-managed teams. As predicted, results indicated that a ‘high care’ atmosphere among team members favours both the transfer and the creation of knowledge. Findings also showed that certain management initiatives foster this type of atmosphere. The study concludes with some recommendations for future research in this area.
Blood, Thicker than Water: Interpersonal Relations and Taiwanese Investment in Southern China

Transnational capitals have not been as footloose as theorists of a new international division of labor have proposed. Taiwanese direct investment in southern China represents a case where transnational capital flows are shaped by cultural and institutional conditions. The effectiveness of Taiwanese direct investment in southern China is achieved through the interpersonal networks established between Taiwanese investors and local Chinese officials. Such networks, in turn, are based on two major conditions. First, the newly gained economic autonomy of local governments in southern China, as well as the Chinese bureaucratic tradition of flexible interpretation and implementation of laws. Such an institutional context provided the space for the local state in China to bypass the scrutiny of the central state and to link up with the world economy directly through overseas Chinese capitals. Second, cultural and linguistic affinity between the Taiwanese investors and local Chinese officials have provided the tools for establishing interpersonal networks between Taiwanese investors and Chinese local officials through the principle of gift exchange.
Activation of Sirt1 by Resveratrol Inhibits TNF-α Induced Inflammation in Fibroblasts

Inflammation is one of main mechanisms of autoimmune disorders and a common feature of most diseases. Appropriate suppression of inflammation is a key resolution to treat the diseases. Sirtuin1 (Sirt1) has been shown to play a role in regulation of inflammation. Resveratrol, a potent Sirt1 activator, has anti-inflammation property. However, the detailed mechanism is not fully understood. In this study, we investigated the anti-inflammation role of Sirt1 in NIH/3T3 fibroblast cell line. Upregulation of matrix metalloproteinases 9 (MMP-9), interleukin-1beta (IL-1β), IL-6 and inducible nitric oxide synthase (iNOS) were induced by tumor necrosis factor alpha (TNF-α) in 3T3 cells and resveratrol suppressed overexpression of these pro-inflammatory molecules in a dose-dependent manner. Knockdown of Sirt1 by RNA interference caused 3T3 cells susceptible to TNF-α stimulation and diminished anti-inflammatory effect of resveratrol. We also explored potential anti-inflammatory mechanisms of resveratrol. Resveratrol reduced NF-κB subunit RelA/p65 acetylation, which is notably Sirt1 dependent. Resveratrol also attenuated phosphorylation of mammalian target of rapamycin (mTOR) and S6 ribosomal protein (S6RP) while ameliorating inflammation. Our data demonstrate that resveratrol inhibits TNF-α-induced inflammation via Sirt1. It suggests that Sirt1 is an efficient target for regulation of inflammation. This study provides insight on treatment of inflammation-related diseases.
Numerical modelling and experimental investigation on welding residual stresses in large-scale tubular K-joints

This paper is devoted to the experimental and numerical assessment of residual stresses created by welding in the region surrounding the weld toe of tubular K-shaped joints (i.e. region most sensitive to fatigue cracking). Neutron-diffraction measurements were carried out on K-joints cut from large-scale truss beams previously subjected to high cycle fatigue. Tri-axial residual stresses in the transverse, longitudinal and radial direction were obtained from the weld toe as a function of the depth in the thickness of the tube wall. In addition, thermomechanical analyses were performed in three-dimensional using ABAQUS and MORFEO finite element codes. Experimental and numerical results show that, at and near the weld-toe surface, the highest residual stresses are critically oriented perpendicularly to the weld direction, and combined with the highest externally applied stresses. Based on a systematic study on geometric parameters, analytical residual stress distribution equations with depth are proposed.
Influence of sleep on tensor palatini EMG and upper airway resistance in normal men.

We propose that a sleep-induced decrement in the activity of the tensor palatini (TP) muscle could induce airway narrowing in the area posterior to the soft palate and therefore lead to an increase in upper airway resistance in normal subjects. We investigated the TP to determine the influence of sleep on TP muscle activity and the relationship between changing TP activity and upper airway resistance over the entire night and during short sleep-awake transitions. Seven normal male subjects were studied on a single night with wire electrodes placed in both TP muscles. Sleep stage, inspiratory airflow, transpalatal pressure, and TP moving time average electromyogram (EMG) were continuously recorded. In addition, in two of the seven subjects the activity (EMG) of both the TP and the genioglossus muscle simultaneously was recorded throughout the night. Upper airway resistance increased progressively from wakefulness through the various non-rapid-eye-movement sleep stages, as has been previously described. The TP EMG did not commonly demonstrate phasic activity during wakefulness or sleep. However, the tonic EMG decreased progressively and significantly (P less than 0.05) from wakefulness through the non-rapid-eye-movement sleep stages [awake, 4.6 +/- 0.3 (SE) arbitrary units; stage 1, 2.6 +/- 0.3; stage 2, 1.7 +/- 0.5; stage 3/4, 1.5 +/- 0.8]. The mean correlation coefficient between TP EMG and upper airway resistance across all sleep states was (-0.46). This mean correlation improved over discrete sleep-awake transitions (-0.76). No sleep-induced decrement in the genioglossus activity was observed in the two subjects studied. (ABSTRACT TRUNCATED AT 250 WORDS)
