Relationship between Entrepreneurial Orientation and Project Management Maturity in Brazilian Software Firms

This paper aims to analyze the relationship between entrepreneurial orientation and project management maturity in software firms. Initially, the literature concerning both matters has been approached. Then, a conceptual model which suggests that the entrepreneurial orientation is positively related to the project management maturity, has been proposed. In order to evaluate this model, the Structural Equation Modeling technique has been adopted through the Partial Least Square method using a sample of 102 questionnaires given by managers of Brazilian software firms. The model was validated and the study hypothesis confirmed. The results of the study reveal that there is a positive relationship between entrepreneurial orientation and project management maturity in the surveyed firms. Thus, innovativeness, risk-taking and proactiveness exert a positive impact on the project management maturity, which is characterized by integration management, scope management, time management, cost management, quality management, human resources management, communications management, risk management and procurement management. The results collaborate with the theoretical discussions surrounding these subjects contributing to seal literature gap to combine entrepreneurship and project management. As managerial contributions, the study provides executives and managers to have a general view that the entrepreneurial orientation exerts beneficial impacts on the project management maturity.
Characterization of the cross‐bridge force‐generating step using inorganic phosphate and BDM in myofibrils from rabbit skeletal muscles

The inhibitory effects of inorganic phosphate (Pi) on isometric force in striated muscle suggest that in the ATPase reaction Pi release is coupled to force generation. Whether Pi release and the power stroke are synchronous events or force is generated by an isomerization of the quaternary complex of actomyosin and ATPase products (AM.ADP.Pi) prior to the following release of Pi is still controversial. Examination of the dependence of isometric force on [Pi] in rabbit fast (psoas; 5‐15 °C) and slow (soleus; 15‐20 °C) myofibrils was used to test the two‐step hypothesis of force generation and Pi release. Hyperbolic fits of force‐[Pi] relations obtained in fast and slow myofibrils at 15 °C produced an apparent asymptote as [Pi]∞ of 0.07 and 0.44 maximal isometric force (i.e. force in the absence of Pi) in psoas and soleus myofibrils, respectively, with an apparent Kd of 4.3 mm in both. In each muscle type, the force‐[Pi] relation was independent of temperature. However, 2,3‐butanedione 2‐monoxime (BDM) decreased the apparent asymptote of force in both muscle types, as expected from its inhibition of the force‐generating isomerization. These data lend strong support to models of cross‐bridge action in which force is produced by an isomerization of the AM.ADP. Pi complex immediately preceding the Pi release step.
Morphology and syntax in late talkers at age 5.

PURPOSE This study reports age 5 morphology and syntax skills in late talkers identified at age 2 (n=34) and typically developing comparison children (n=20). RESULTS The late talkers manifested significant morphological delays at ages 3 and 4 relative to comparison peers. Based on the 14 morphemes analyzed at age 5, the only significant group difference was on the third person regular -s inflection. This was also the only significant difference when we compared late talkers with continuing delay, late bloomers (who scored within 1 standard deviation of the comparison group in mean length of utterance), and typically developing peers. The late talker and comparison children differed greatly in mean total scores on the Index of Productive Syntax (Scarborough, 1990), a measure of syntactic complexity. The group with continuing delay scored significantly lower on the IPSyn than the late bloomer and typically developing groups, which did not differ from each other. CONCLUSIONS Findings are consistent with the higher order language group differences found through adolescence in these late talkers relative to comparison peers with similar socioeconomic status and similar nonverbal abilities, supporting the notion that late talkers have an ongoing weakness in language endowment that manifests differently over the course of development.
Self-perceived and unmet general health need among PLWHA in Nigeria.

OBJECTIVE This study set out to determine the self-reported unmet health needs of people living with HIV/AIDS (PLWHA) in a Nigerian population. METHODS A prospective study conducted among consecutive 209 consenting PLWHA in the South-western Nigeria; who sought for care in the Obafemi Awolowo University Teaching Hospitals complex, Ile-Ife and General Hospital, Ilesa were recruited. Participants completed a comprehensive survey seeking information to determine their unmet needs in the following areas: Medication, Dental, Mental, Home care, Hospital admission, access to antiretroviral therapy and emergency services. RESULTS One or more unmet needs were reported by 79.4% of the sample. Needs for medication, home-based care and mental care were more likely to be unmet. There was a statistically significant relationship between unmet needs and living arrangements (p < 0.05). CONCLUSIONS Perceived oral health status was the factor that best predicted the unmet need. Perceived oral health status of these patients should be improved to reduce the level of the unmet needs.
Fast Passivity Enforcement for S-Parameter Models by Perturbation of Residue Matrix Eigenvalues

Rational macromodels must be passive in order to guarantee a stable simulation. This paper introduces a fast approach for enforcing passivity for S-parameter based pole-residue models, using a similar method previously introduced for Y-parameter models. The approach is based on perturbing the elements of the residue matrices with the perturbed residue matrix eigenvalues as free variables. This gives large savings for the CPU time and memory requirements. The implementation does not require sparse computations. Combining the passivity enforcement step with iterations and fast passivity assessment via a half-size test matrix gives a globally passive model. Error control strategies are implemented via least squares weighting. The approach is demonstrated for a two-port microwave filter, a four-port interconnect, a 48-port low-order package model, and a 28-port high-order package model.
The Heritability of Language: A Review and Metaanalysis of Twin, Adoption, and Linkage Studies

Some researchers argue that the ability to acquire and use language is largely the result of innate predispositions that are specific to language (the INNATENESS HYPOTHESIS). If the innateness hypothesis is correct, these predispositions must be encoded for in our DNA. This article reviews more than one hundred genetic studies of language. The results of these studies strongly suggest that genetic factors play a role in the variation in the rate of language acquisition and linguistic proficiency attained by children and adults. Genetic factors account for much of the variance in linguistic abilities among people with written or spoken language disorders and some of the variance in linguistic abilities among normal people. In addition to heritable factors that influence both nonverbal and verbal abilities, there appear to be genetic factors that specifically influence linguistic abilities. Furthermore, some studies suggest that different genetic factors are involved in different aspects of language (e.g. written language vs. spoken language; lexical vs. syntactic abilities).
Online Information Acquisition and Investor Trading

We examine the empirical associations between online information acquisition and several aspects of investors’ trading activities. We find that trading volume and buy-sell imbalance between small and large traders are positively associated with abnormal ticker search on Google. These positive trading-search associations are more pronounced for firms with large accruals, during earnings announcement periods, and in more recent years. Our evidence is consistent with information acquisition triggers investor disagreement.
Setting up the First Registry for Inflammatory Bowel Disease, Suspected to Primary Immunodeficiency Diseases in Iran

Background: inflammatory bowel disease (IBD) has been considered a hyperinflammatory state due to disturbed interactions between the immune system and the commensal bacterial flora of the gut and suggesting IBD asa primary immunodeficiencies (PID). Therefore a registry launched about IBD, suspected to PID (IBDSPID) for the first time in Iran to raise awareness about this disease, to identify its risk factors, to early diagnosis and treatment. Materials and Methods: Among of 365 patients, 39 have inclusion criteria that were as below:(1) IBD diagnosis before age 5 years (2) Resistance to conventional therapy of IBD (3) Severe IBD (4) Signs of SPID (Recurrent sinus or ear infections or pneumonias within a 1 year period; failure to thrive; poor response to prolonged use of antibiotics; persistent thrush or skin abscesses; or a family history of PID). The achieved data of patients was computerized using the MySQL Database. Results: The mean age was 32.92± 15.90 years old. 51.3% of patients were males. The Ulcerative colitis was the most common type of diagnosed IBDSPID. Among patients, 23.1, 29.4, 50.0% were mild, moderate, severe cases of IBDSPID respectively. Age at onset of IBD in the majority of patients was after 17 years old. Among patients, 12.9% had resistance to drugs. The percent of patients with history of autoimmune, allergy, PID and SPID was 33.3, 33.3, 89.7, 12.9; respectively. consanguinity, family history of IBD, autoimmune disease and allergy, was 47.4%, 15.4%, 25.7% and 28.2%; respectively, also the percent of family history of PID and malignancy was 2.6 and 20.5; respectively. Conclusions: This successful registry provides useful data on IBD especially with SPID and therefor can help audit and research purposes Mainconclusions: This registry increases the awareness about this disease for determination the prevalence, early diagnosis and effective treatment.

ENVIRONMENTAL IMPACTS OF WORKING CONDITIONS IN PAINT FACTORIES WORKERS IN THE HASHEMITE KINGDOM OF JORDAN (FIELD STUDY)

This paper attempts to analyze the factors that affect the internal and external environmental conditions on workers of the Jordanian paints factories, in terms of the degree of satisfaction with these conditions and their impact on the case of the general satisfaction of these institutions, As well as the impact on productivity and career on the state of job rotation. The results showed that there is a strong relation between these variables and employee satisfaction and stability, especially the case of the internal conditions, with minor variations among worker categories, but the effects on productivity were not strong. The empirical findings will certainly help both researchers and practitioners to integrate the internal and external environmental conditions on workers of the Jordanian paints factories In order to get a better understanding of the degree of satisfaction.
The effect of dividend policy on market value : UK empirical study

This study tackles the relationship between dividend policy and market value of companies in the UK through three empirical models. The aim of the first model was to test the validity of the Irrelevant Theory empirically by exploring the relationship between dividend type (cash dividend, share dividend and share repurchase), earnings (EPS) and investment policy (retained earnings per share) with the market value of a company. This is achieved through the use of annual and semi-annual data for 362 companies in different UK sectors by adopting Panel Data for the period extending from 1998 to 2007 (twenty periods), where the fixed-effect (within) regression model was used to examine this sample . The second model examines if companies favour the investment policy dividend policy by investigating whether or not companies follow a residual dividends policy. This has been identified by following the methodology of Baker and Smith (2006), based on the calculation of Standardized Free Cash Flow (SFCF) for 590 UK companies in different sectors for the period from 1998 to 2007 by using annual data. The third model seeks to explore managerial preferences regarding dividend type and the most important factors affecting the company management when setting dividends policy. In this respect, the importance of the following factors has been tested: the company’s market value; the financing decision; the investment decision; signaling theory; agency theory; and shareholder structure. The questionnaire methodology used for this model where it was distributed to 1319 UK companies in different sectors. The number of responses was 208 responses is equivalent to 15.77% of the total distributed). The study arrived at a number of important results that can be summarized as follows: 1) The invalidity of the Irrelevant Theory, as the results show that there is a relationship between dividend policy and market value of a company; 2) There is a relationship between earnings, investment policy and the market value, which indicates that the dividends policy, announced earnings and investment policy work together in affecting the market value of a company; 3) UK companies, on the whole, do not adopt a residual dividends policy, implying no preference for investment policy over dividend policy, except for the two sectors banking and insurance companies where the results showed that they follow the residuals dividends policy 4) Most UK companies’ managements prefer cash dividends to other venues choices because of its easy implementation; and 5) The most important factor affecting UK companies’ managements when they set their dividends policy is shareholder structure while the least factor listed in importance is agency theory.
The Cdc42p GTPase and Its Regulators Nrf1p and Scd1p Are Involved in Endocytic Trafficking in the Fission YeastSchizosaccharomyces pombe *

Nrf1p was first identified in a screen for negative regulators of the Cdc42p GTPase. Overexpression of Nrf1p resulted in dose-dependent lethality, with cells exhibiting an ellipsoidal morphology and abnormal vacuolar phenotypes including an increase in vacuolar fusion. Green fluorescent protein (GFP)-Cdc42p and GFP-Nrf1p colocalized to vacuolar membranes and GFP-Nrf1p vacuolar localization depended on Scd1p, the Schizosaccharomyces pombe homolog of the Cdc24p guanine nucleotide exchange factor. In this study, site-directed mutagenesis was conducted on Nrf1p to determine its functional domains. Mutations in the three putative transmembrane domains resulted in mislocalization of GFP-Nrf1p and an inability to induce lethality, suggesting a loss of function. Mutations in the second extramembranous loop of Nrf1p also resulted in a loss of function and altered the ability of GFP-Nrf1p to localize to vacuolar membranes. Analysis of Δnrf1 and Δscd1mutants revealed defects in endocytosis. In addition, overexpression of constitutively active Cdc42G12Vp resulted in an increase in endocytosis and an ability to rescue the endocytic defects in Δnrf1 and Δscd1 cells. These data are consistent with Nrf1p and Scd1p being necessary for efficient endocytosis, possibly through the regulation of Cdc42p.
Generalisation towards Combinatorial Productivity in Language Acquisition by Simple Recurrent Networks

Language exhibits combinatorial productivity as complex constructions are composed of simple elements in a linear or hierarchical fashion. Complexity arises as one cannot be exposed to all possible combinations during ontogeny and yet to master a language one need to be, and very often is, able to generalise to process and comprehend constructions that are of novel combinations. Accounting for such an ability is a current challenge being tackled in connectionist research. In this study, we will first demonstrate that connectionist networks do generalise towards combinatorial productivity followed by an investigation of how the networks could achieve that
Measuring the Perception of Financial Risk Tolerance: A Tale of Two Measures

The assessment of financial risk tolerance, as a tool for managing expectations of portfolio volatility, is essential to goal attainment. This study compares two empirical measures of risk tolerance and separately examines the association between these measures of risk tolerance and asset allocation. The instruments used to determine investors’ perception of financial risk tolerance are the Survey of Consumer Finance’s (SCF) single-question measure and a 13-item, multidimensional measure developed by Grable and Lytton (1999). A sample comprised of 328 respondents, predominantly faculty and staff at colleges and universities in the Southwest, completed a 38-question, web-based survey. Results suggest that, while both scales are associated with preference for risky or non-risky asset allocation among respondents, the 13-item scale has greater explanatory power.

Cyclical Reallocation of Workers Across Large and Small Employers

Search-and-matching models with on-the-job search and firm size yield the prediction that job-to-job flows reallocate workers from smaller to larger firms. Recent papers have extended such models to explain the cyclicality of employment at large vs. small firms. In this paper, we use linked employer-employee data for the U.S. to provide direct evidence on worker reallocation by firm size. We find that job-to-job flows do not generally move workers from smaller to larger employers. Instead, we show that workers moving directly from one job to another more frequently move from large firms to small firms than the reverse. This is despite the fact that large businesses rely more on poaching workers from other firms when hiring and small businesses hire largely from the pool of nonemployed, results that are consistent with the theory. Regarding the cyclical nature of this reallocation, we find that poaching hires are highly procyclical for both large and small firms. Yet despite the cyclical nature of poaching, net reallocation across firm size classes via poaching is relatively stable across the business cycle. The implication is that net poaching by size class is relatively small in magnitude at all phases of the cycle. We find more supportive evidence of the predictions of recent theories regarding net poaching between small and large firms in times of tight labor markets when we focus on mature firms. Even here however the quantitative effects are small.
Efficacy of selective laser trabeculoplasty in primary angle-closure glaucoma: a randomized clinical trial.

IMPORTANCE Selective laser trabeculoplasty (SLT) should be explored as a therapeutic option in eyes with angle closure. OBJECTIVE To assess the intraocular pressure (IOP)-lowering efficacy of SLT in eyes with primary angle closure (PAC) and PAC glaucoma (PACG). DESIGN, SETTING, AND PARTICIPANTS Randomized clinical trial at tertiary eye care institutions of 100 patients diagnosed as having PAC or PAC glaucoma in which the angles had opened at least 180° (visible posterior trabecular meshwork on gonioscopy) after laser iridotomy. Recruitment and baseline were completed from June 2009 to April 2012 and 6-month follow-up was completed from December 2009 to November 2012. INTERVENTIONS Eligible patients with a baseline IOP greater than 21 mm Hg were randomized to either SLT or prostaglandin analog (PGA; travoprost, 0.004%). The SLT was repeated if the IOP reduction was less than 20.0% from baseline at the 1- or 3-month follow-up visit. MAIN OUTCOMES AND MEASURES The primary outcome measure was the change in IOP from baseline to the final follow-up visit (at 6 months). The frequency of additional postoperative treatments and complications were secondary outcomes. RESULTS Fifty patients (96 eyes) were randomized to SLT and 50 patients (99 eyes) to PGA medical therapy. At 6 months, 49 patients in the SLT group and 47 in the PGA group completed follow-up. Analysis was based on intent to treat. At 6 months, IOP decreased by 4.0 mm Hg (95% CI, 3.2-4.8) in the SLT group (P < .001) and by 4.2 mm Hg (95% CI, 3.5-4.9) in the PGA group (P < .001). There were no differences between the SLT and PGA groups in the absolute mean reduction of IOP (4.0 vs 4.2 mm Hg, respectively; P = .78) or in the percentage of reduction in IOP (16.9% vs 18.5%, respectively; P = .52). Complete success (IOP ≤21 mm Hg without medications) was achieved in 60.0% eyes of the SLT group, compared with 84.0% of eyes in the PGA group (P = .008). No patients required glaucoma surgery. Additional medications were required in 22.0% of patients in the SLT group compared with 8.0% in the PGA group (P = .05). One patient in the SLT group (2.0%) had a transient posttreatment IOP spike greater than 5 mm Hg. The mean endothelial cell count showed a significant decrease from baseline in the SLT arm (4.8% decrease; P = .001). No other events such as persistent uveitis or increase in peripheral anterior synechiae were noted in eyes that underwent SLT. Two patients in the PGA group exited owing to drug-related complications (1 patient with uveitis and 1 with allergic conjunctivitis). CONCLUSIONS AND RELEVANCE Eyes with PAC or PACG respond to SLT in the short term, but the overall long-term therapeutic effectiveness needs further evaluation. TRIAL REGISTRATION clinicaltrials.gov Identifier: NCT01004900.
Determinants of Capital Structure in Non-Financial Companies

In this paper, we evaluate rm-, industry- and country-specic factors determining a rm’s capital structure. The empirical validity of several capital structure theories has been ambiguous so far. We shed light on the main drivers of leverage and depict dierences in industry and country characteristics. Using a short panel data set with a large cross-section, we are able to show that rm size, industry leverage, industry growth and tax shield
Echographic findings in sertoli cell tumor of the testis

A 30-yr-old man complained that the right side of his scrotum had been painlessly increasing in size for several months. Physical examination was normal except for a nontender right scrotal mass the size and consistency of a ripened cantelope. Ultrasonic sections showed the scrotal swelling was caused by a combination of a hydrocele and a large testicular mass (Fig 1A and B). The mass consisted of an anteriorly located solid element from which numerous septations radiated. These septations created multiple fluid-filled spaces of varying sizes and shapes. The overall appearance could be best described as a multicystic tumor arranged in a “spoke-wheel” configuration. Sonograms of the abdomen showed no ascites, adenopathy, or urinary tract abnormality. The surgical specimen from a hemiscrotectomy weighed 3 kg. Bisection of the bulky mass showed it was a multicystic tumor surrounded by 1,500 ml of hydrocele fluid. The gross appearance of the tumor corresponded precisely with the ultrasonic image. Microscopic sections revealed a Sertoli cell neoplasm with invasion of the epididymis and tunica albuginea. Lymph nodes removed during a retroperitoneal node dissection done two weeks after the scrotal surgery were normal.
