andr 21 402 Mp 580 File # 02 em plasmid that expresses transmembrane

The interaction between stem cell factor (SCF), a ligand produced by Sertoli cells, and its c-kit receptor on germ cells is necessary for successful spermatogenesis in animal models. SCF can be alternatively spliced into soluble and transmembrane forms, and it is the transmembrane form that is required for spermatogenesis in rodents. c-Kit receptors are also present on Leydig cells, and soluble SCF has been implicated in the regulation of testosterone production. This study had two goals: To test the hypothesis that the extent of germ cell production in human males is correlated with the expression of transmembrane SCF, and to examine the relationship between testosterone production and the expression of soluble SCF in humans. Reverse transcriptase polymerase chain reaction was used to determine the ratio of transmembrane-to-soluble SCF in testicular tissue. Clinical analysis, hormonal measurements, and histological methods were used to evaluate the causes of infertility and to seek correlations with the pattern of SCF expression. SCF was preferentially expressed as the transmembrane type in all testicular samples, regardless of the state of germ cell production. Furthermore, the percent of transmembrane SCF expression was independent of clinical and histopathological diagnosis (rs 0.111, n 28) and unrelated to the extent of spermatogenesis. This contrasts with rat models of testicular injury that exhibit a decreased proportion of transmembrane SCF with atrophy. A significant correlation (rs 0.665, P .02, n 16) was found between testosterone levels and percent soluble SCF, which suggests that, in humans, there may be a regulatory interaction between soluble SCF and testosterone.
Mediating role of organizational commitment in the relationship between human resource management practices and employee engagement

Purpose The purpose of this paper is to examine the mediating role of organizational commitment (OC) on the relationship between human resource management (HRM) practices and employee engagement among banking employees in the context of an emerging economy namely Bangladesh. Design/methodology/approach The survey data include 383 employees from 30 private commercial banks in Bangladesh. For analyzing the data, structural equation modeling is employed with the bootstrapping method. Findings This study finds that HRM practices such as career advancement, employee participation, job security, performance feedback, rewards and recognition, training and development are the significant predictors of employee engagement. Results also identify OC as a partial mediator on HRM practices and employee engagement relationship which suggest that direct relationship of predictors and criterion variables are stronger than indirect association. More interestingly, findings indicate that the mechanism of black-box stage is not always work on the relationship between HRM practices and employee performance. Originality/value Exploring the role of OC on the relationship between HRM practices and employees’ behavioral outcome, i.e. employee engagement, is appeared as an initial effort in the academic literature. Furthermore, empirical research that examines the association of different organizational factors with employee engagement through OC is rarely been investigated. Thus, the findings of this study act as a strategic tool for the bank managers to design their organizational policies in such a way that fosters their employee’ level of engagement.
Almost-Graphic Matroids

A nongraphic matroid M is said to be almost-graphic if, for all elements e, either M\e or M/e is graphic. We determine completely the class of almost-graphic matroids, thereby answering a question posed by Oxley in his book ''Matroid Theory. '' A nonregular matroid is said to be almost-regular if, for all elements e, either M\e or M/e is regular. An element e for which both M\e and M/e are regular is called a regular element. We also determine the almost-regular matroids with at least one regular element.
Airborne Signals from a Wounded Leaf Facilitate Viral Spreading and Induce Antibacterial Resistance in Neighboring Plants

Many plants release airborne volatile compounds in response to wounding due to pathogenic assault. These compounds serve as plant defenses and are involved in plant signaling. Here, we study the effects of pectin methylesterase (PME)-generated methanol release from wounded plants (“emitters”) on the defensive reactions of neighboring “receiver” plants. Plant leaf wounding resulted in the synthesis of PME and a spike in methanol released into the air. Gaseous methanol or vapors from wounded PME-transgenic plants induced resistance to the bacterial pathogen Ralstonia solanacearum in the leaves of non-wounded neighboring “receiver” plants. In experiments with different volatile organic compounds, gaseous methanol was the only airborne factor that could induce antibacterial resistance in neighboring plants. In an effort to understand the mechanisms by which methanol stimulates the antibacterial resistance of “receiver” plants, we constructed forward and reverse suppression subtractive hybridization cDNA libraries from Nicotiana benthamiana plants exposed to methanol. We identified multiple methanol-inducible genes (MIGs), most of which are involved in defense or cell-to-cell trafficking. We then isolated the most affected genes for further analysis: β-1,3-glucanase (BG), a previously unidentified gene (MIG-21), and non-cell-autonomous pathway protein (NCAPP). Experiments with Tobacco mosaic virus (TMV) and a vector encoding two tandem copies of green fluorescent protein as a tracer of cell-to-cell movement showed the increased gating capacity of plasmodesmata in the presence of BG, MIG-21, and NCAPP. The increased gating capacity is accompanied by enhanced TMV reproduction in the “receivers”. Overall, our data indicate that methanol emitted by a wounded plant acts as a signal that enhances antibacterial resistance and facilitates viral spread in neighboring plants.
Self-perceived competency and self-perceived employability in higher education: the mediating role of career adaptability

ABSTRACT In a time where employability issues are at the top of political agendas and employment prospects represent the most important predictor of satisfaction with higher education, the question about how higher education institutions can better prepare their graduates for the labour market becomes increasingly important. Taking the career construction theory as its main theoretical framework, this study intends to explore the role of career adaptability as a mediating variable between competencies developed during higher education studies and perceived employability. The participants were 373 students attending the last year of master’s degree programmes, who completed the Career Adapt-Abilities Scale, the Self-Perceived Employability Scale, and a survey exploring students’ perceptions about their competencies at the end of their university programme. The results indicated that career adaptability has a mediating role between self-perceived competency and self-perceived employability. Although academic competencies represent a prerequisite for employability, the findings suggest that graduating students should also be equipped with career management resources to handle their own attributes and to transition smoothly into the current labour market. These findings are particularly important because they reveal how higher education institutions can foster the employability of graduates by integrating training opportunities in career management during graduation programmes.
Efficient Analytical Fragility Function Fitting Using Dynamic Structural Analysis

Estimation of fragility functions using dynamic structural analysis is an important step in a number of seismic assessment procedures. This paper discusses the applicability of statistical inference concepts for fragility function estimation, describes appropriate fitting approaches for use with various structural analysis strategies, and studies how to fit fragility functions while minimizing the required number of structural analyses. Illustrative results show that multiple stripe analysis produces more efficient fragility estimates than incremental dynamic analysis for a given number of structural analyses, provided that some knowledge of the building's capacity is available prior to analysis so that relevant portions of the fragility curve can be approximately identified. This finding has other benefits, given that the multiple stripe analysis approach allows for different ground motions to be used for analyses at varying intensity levels, to represent the differing characteristics of low-intensity and high-intensity shaking. The proposed assessment approach also provides a framework for evaluating alternate analysis procedures that may arise in the future.
Two decades of OH variability as inferred by an inversion of atmospheric transport and chemistry of methyl chloroform

Abstract. We developed an iterative inverse method to infer inter-annual sources and sinks of methyl chloroform (MCF) from atmospheric measurements, on a monthly basis. The methodology is presented and used to estimate two decades of OH variability between 1980 and 2000, using varying meteorology. When OH concentrations are adjusted with loose prior errors and MCF emissions are adjusted within inventory bounds, we show that substantial OH inter-annual variability (8.5±1.0% of the mean) and trend (-0.7%.yr-1) are necessary to match MCF observations. This result is confirmed by a series of sensitivity tests addressing main limitations of previous studies. However, we show that it is also possible to match MCF observations with a 65% reduction of OH year-to-year variations and a 60% reduction of absolute OH trend, but still a consistency of inferred emissions with inventory values at a ±2σ level. On the other hand, the phase of inferred OH variations is a more robust feature of our set of inversions. Overall, MCF inversions can only provide a range of OH variations unless inventory uncertainties are further reduced.
Motivational Orientations of Secondary School EFL Learners toward Language Learning

This study aimed to examine to what extent Turkish EFL learners’ L2 motivational dispositions which are ideal L2 self, ought-to L2 self and language learning experiences predict their intended effort for language learning. The study was designed from a quantitative perspective in which the participants were given a composite instrument. The study was conducted at a state run secondary school in Turkey and the participants were 254 students including 5 th , 6 th , 7 th and 8 th graders. The results indicated that secondary level Turkish EFL students have high scores on all of the L2 motivation variables. However, the statistical analyses suggested that the participants’ level of ought-to L2 self was significantly higher than their level of ideal L2 self. It was also seen that when the participants got older, their levels of ought-to L2 self appeared to indicate a decreasing trend. Besides, the results asserted that the secondary school students’ intended effort for learning a language was found to be predicted mostly by language learning experiences, then ought-to L2 self and lastly ideal L2 self, according to hierarchical multiple regression analysis. The results were discussed in line with L2 motivational self system studies in the literature and it was concluded that the results in favor of ought-to L2 self might imply the existence of peer or community pressure in language learning process of secondary school EFL students in Turkish context.
Effect of a Virtual Environment on the Development of Mathematical Skills in Children with Dyscalculia

In this study, we show the effectiveness of a virtual environment comprising 18 computer games that cover mathematics topics in a playful setting and that can be executed on the Internet with the possibility of player interaction through chat. An arithmetic pre-test contained in the Scholastic Performance Test was administered to 300 children between 7 and 10 years old, including 162 males and 138 females, in the second grade of primary school. Twenty-six children whose scores showed a low level of mathematical knowledge were chosen and randomly divided into the control (CG) and experimental (EG) groups. The EG participated to the virtual environment and the CG participated in reinforcement using traditional teaching methods. Both groups took a post-test in which the Scholastic Performance Test (SPT) was given again. A statistical analysis of the results using the Student's t-test showed a significant learning improvement for the EG and no improvement for the CG (p≤0.05). The virtual environment allows the students to integrate thought, feeling and action, thus motivating the children to learn and contributing to their intellectual development.
Related Factors and Adverse Neonatal Outcomes in Women with Preterm Premature Rupture of Membranes Complicated by Histologic Chorioamnionitis

Background The aim of this study was to identify factors predicting histologic chorioamnionitis (HCA) in women with preterm premature rupture of membranes (PPROM). Material/Methods We retrospectively enrolled 371 women diagnosed with PPROM at less than 34 weeks of gestation at the Second Affiliated Hospital of Wenzhou Medical University between January 2008 and December 2012. HCA was diagnosed by placental histopathology in 70% of participants. Binary logistic regression was used to identify factors associated with HCA and neonatal outcomes. Results Patient age, rate of parity, tocolysis, cesarean section, serum C reactive protein (CRP) level at admission, white blood cell count, and latency duration did not significantly differ between the 2 groups. Binary logistic regression revealed that oligohydramnios at admission, gestational age at PPROM, and serum CRP >8 mg/L before delivery were significantly associated with HCA. Gestational age at delivery and birth weight were significantly lower in HCA patients than control patients. The rate of 1-min Apgar score <7, abnormal neonatal intracranial ultrasound findings, neonatal pneumonia, bronchopulmonary dysplasia, early-onset neonatal sepsis, and mortality were higher in HCA patients, but no significant difference was observed in the incidence of neonatal respiratory distress syndrome, necrotizing enterocolitis, hyperbilirubinemia, or hypoglycemia. Conclusions Younger gestational age at time of PPROM, higher CRP level before delivery, and oligohydramnios at admission in women with PPROM are associated with HCA, and HCA is associated with some adverse neonatal outcomes.
Parametric Delay Test of Post-Bond Through-Silicon Vias in 3-D ICs via Variable Output Thresholding Analysis

A parametric delay fault could arise in a through-silicon via (TSV) of a 3-D IC due to a manufacturing defect. Identification of such a fault is essential for fault diagnosis, yield-learning, and/or reliability screening. In this paper, we present an innovative design-for-testability technique called variable output thresholding. We discovered that by dynamically switching the output of a TSV from a normal inverter to a Schmitt-Trigger inverter, the parametric delay fault on the TSV can be characterized and detected. SPICE simulation reveals that this technique remains effective even when there is significant process variation. A scalable test infrastructure indicates that the test time is modest at only 17.2 ms for 1024 TSVs and 648.8 ms for 32768 TSVs when the test clock is running at 10 MHz.
Capital Structure of Agricultural Businesses and its Determinants

The article deals with the analysis of the capital structure of agricultural businesses of legal entities and its determinants. It discusses the effect of selected determinants on the capital structure of businesses, expressed by way of three categories of indebtedness. The analysis of the determinants of capital structure is conducted by way of multiple linear regression. Also being verified is the hypothesis of whether the effect of individual determinants of capital structure is in accordance with the theoretical assumptions of conditional theories of capital structure and empirical studies. The panel data for the article were acquired from the Albertina database, provided by the company Soliditet, s.r. o. Specifically, the data used were those from accounting statements for the years 2004 – 2010 for the agricultural businesses of legal entities. In total, the object of examination was 16075 businesses, which were divided up according to legal forms (joint stock company, cooperative, and limited liability company) and subsequently the relevant size group. In total, 18 groups of businesses were created, whereby the average balance and profit and loss account were drawn up for each group, on the basis of which the relevant calculations were conducted. The article is a part of the grant project IGA 20121069 "Identification of the main determinants of the result of economic activity of agricultural businesses of legal entities and the determination of their specifics" and of the institutional research intentions MSM 6046070906 "Economics sources of Czech agriculture and their efficient use in the context of multifunctional agri-food systems".
Study on the 3D shape of active cord mechanism

Snake-like robots and hyper-redundant manipulators have been called active cord mechanism (ACM), and they have been one of fields of robotics. However, general study on the spatial shape of ACM has not been conducted enough so far. In this paper, we propose a effective method for analysis of the 3D shape of ideal continuous ACM models. In addition, we show some important characteristics of ACM using this method. The results help us understand the characteristics and possibility of ACM
Flag algebras

Abstract Asymptotic extremal combinatorics deals with questions that in the language of model theory can be re-stated as follows. For finite models M, N of an universal theory without constants and function symbols (like graphs, digraphs or hypergraphs), let p(M, N) be the probability that a randomly chosen sub-model of N with ∣M∣ elements is isomorphic to M. Which asymptotic relations exist between the quantities p(M1,N),…, p(Mh,N), where M1,…, M1, are fixed “template” models and ∣N∣ grows to infinity? In this paper we develop a formal calculus that captures many standard arguments in the area, both previously known and apparently new. We give the first application of this formalism by presenting a new simple proof of a result by Fisher about the minimal possible density of triangles in a graph with given edge density.

Capacity of Erasure Networks in the Presence of Spatial Network Coding

We study the capacity of a point-to-point erasure network in the presence of a restricted form of network coding, to which we refer as spatial network coding. In spatial network coding, the temporal aspect of coding is absent, i.e., a coding relationship is not created among successive packets sent on each network link, in order to combat link erasures. For a given source-destination pair, there exists a minimum cut rate corresponding to each random instance of the network We prove that the statistical average of such minimum cut rates equals the network capacity for the corresponding unicast session. We also show that this capacity can be higher than the capacity achieved through pure routing. This stands in contrast to the known result for deterministic networks where, in the case of a unicast session, capacities achieved through routing and network coding are equal. In the case of a multicast session, we show that, similar to deterministic networks, the capacity achievable through spatial network coding is equal to the minimum of the capacities of the constituent unicast sessions.
