Entrepreneur‐mentality, gender and the study of women entrepreneurs

Uses the neologism “entrepreneur mentality” – paying implicit homage to Foucault's govermentality – to highlight how an entrepreneurial discourse is mobilized as a system of thinking about women entrepreneurs which is able to make some form of that activity thinkable and practicable, namely: who can be an entrepreneur, what entrepreneurship is, what or who is managed by that form of governance of economic relations? Discourses on women entrepreneurs are linguistic practices that create truth effects. Argues that social studies of women entrepreneurs tend to reproduce an androcentric entrepreneur mentality that makes hegemonic masculinity invisible. They portray women's organizations as “the other”, and sustain social expectations of their difference, thereby implicitly reproducing male experience as a preferred normative value. Taking a deconstructive gaze on how an entrepreneur‐mentality discourse is gendered, reveals the gender sub‐text underpinning the practices of the scientific community that study women entrepreneurs and, in so doing, open a space to question them.
GRACILARIA VERMICULOPHYLLA (RHODOPHYTA, GRACILARIALES) IN THE VIRGINIA COASTAL BAYS, USA: COX1 ANALYSIS REVEALS HIGH GENETIC RICHNESS OF AN INTRODUCED MACROALGA

Gracilaria vermiculophylla (Ohmi) Papenfuss is an invasive alga that is native to Southeast Asia and has invaded many estuaries in North America and Europe. It is difficult to differentiate G. vermiculophylla from native forms using morphology and therefore molecular techniques are needed. In this study, we used three molecular markers (rbcL, cox2‐cox3 spacer, cox1) to identify G. vermiculophylla at several locations in the western Atlantic. RbcL and cox2‐cox3 spacer markers confirmed the presence of G. vermiculophylla on the east coast of the USA from Massachusetts to South Carolina. We used a 507 base pair region of cox1 mtDNA to (i) verify the widespread distribution of G. vermiculophylla in the Virginia (VA) coastal bays and (ii) determine the intraspecific diversity of these algae. Cox1 haplotype richness in the VA coastal bays was much higher than that previously found in other invaded locations, as well as some native locations. This difference is likely attributed to the more intensive sampling design used in this study, which was able to detect richness created by multiple, diverse introductions. On the basis of our results, we recommend that future studies take differences in sampling design into account when comparing haplotype richness and diversity between native and non‐native studies in the literature.
Multiple mechanisms contribute to osmotic inducibility of proU operon expression in Escherichia coli: demonstration of two osmoresponsive promoters and of a negative regulatory element within the first structural gene

Transcription of the proU operon in Escherichia coli is induced several hundredfold upon growth of cells in media of elevated osmolarity. A low-copy-number promoter-cloning plasmid vector, with lacZ as the reporter gene, was used for assaying the osmoresponsive promoter activity of each of various lengths of proU DNA, generated by cloning of discrete restriction fragments and by an exonuclease III-mediated deletion approach. The results indicate that expression of proU in E. coli is directed from two promoters, one (P2) characterized earlier by other workers with the start site of transcription 60 nucleotides upstream of the initiation codon of the first structural gene (proV), and the other (P1) situated 250 nucleotides upstream of proV. Furthermore, a region of DNA within proV was shown to be involved in negative regulation of proU transcription; phage Mu dII1681-generated lac fusions in the early region of proV also exhibited partial derepression of proU regulation, in comparison with fusions further downstream in the operon. Sequences around promoter P1, sequences around P2, and the promoter-downstream negative regulatory element, respectively, conferred approximately 5-, 8-, and 25-fold osmoresponsivity on proU expression. Within the region genetically defined to encode the negative regulatory element, there is a 116-nucleotide stretch that is absolutely conserved between the proU operons of E. coli and Salmonella typhimurium and has the capability of exhibiting alternative secondary structure. Insertion of this region of DNA into each of two different plasmid vectors was associated with a marked reduction in the mean topological linking number in plasmid molecules isolated from cultures grown in high-osmolarity medium. We propose that this region of DNA undergoes reversible transition to an underwound DNA conformation under high-osmolarity growth conditions and that this transition mediates its regulatory effect on proU expression.
Engagement as flourishing: The contribution of positive emotions and coping to adolescents' engagement at school and with learning

Fredrickson's (1998, 2001) broaden and build theory postulates that the experience of frequent positive emotions serves to broaden humans' thoughts and behaviors, resulting in accrual of resources, including coping resources, which catalyze upward spirals toward future well-being. Initial research supports the tenets of broaden and build; however, few if any, studies have examined this theory with children or adolescents, particularly in the context of school experiences. This study explored the role of positive emotions during school, coping, and student engagement among a sample of 293 students in grades 7 to 10. As expected, frequent positive emotions during school were associated with higher levels of student engagement and negative emotions with lower levels of engagement. Positive emotions, but not negative emotions, were associated with adaptive coping, which was then associated with student engagement. The association between positive emotions and engagement was partially mediated by adaptive coping. Results support the broaden and build theory and the role of positive emotions in students' engagement at school and with learning. Implications and future directions for research are discussed. © 2008 Wiley Periodicals, Inc.
Parents are not born, they are made: a critical discourse analysis of an educational magazine in Flanders (Belgium)

Central to this article is a case study of one particular governmental instrument in Flanders, the educational magazine ‘Klasse voor Ouders’ (Klasse for Parents). This popular magazine aims to provide information for and communication with parents as one of the target groups in the educational field. Despite the claimed formal and neutral character, in this study, we assume that ‘Klasse voor Ouders’ plays a larger role by contributing to the (re-)organisation of the public debate. We suggest that through the ‘order of discourse’ and thus, through what is said and written, an educational reality is created in which parents and the government are ‘positioned’ and are asked to reflect on themselves and to act in a well-defined way. By means of a critical discourse analysis in line with Fairclough, we illustrate how parents are understood as having a continuous ‘drive’ for improving the quality of their own parenting practice while the government is positioned as in charge of and in control for creating a kind of ‘parental learning community’.
The relationship between pyuria and infection in patients with indwelling urinary catheters: a prospective study of 761 patients.

BACKGROUND Pyuria is universally considered as essential for identifying urinary tract infections in noncatheterized patients. The utility of pyuria in the catheterized patient, to identify catheter-associated urinary tract infection (CAUTI), has not been adequately defined. METHODS We prospectively studied 761 newly catheterized patients in a university hospital; 82 (10.8%) developed nosocomial CAUTI (> 10(3) colony-forming units per milliliter). While catheterized, each patient was seen daily, a quantitative urine culture was obtained, and the urine white blood cell concentration was measured quantitatively using a hemocytometer. RESULTS The mean urine leukocyte count in patients with CAUTI was significantly higher than in patients without infections (71 vs 4 per microliter; P= .006). Pyuria was most strongly associated with CAUTI caused by gram-negative bacilli (white blood cell count, 121 vs 4 per microliter; P = .03); infection with coagulase-negative staphylococci and enterococci (white blood cell count, 39 vs 4 per microliter; P = .25) or yeasts (white blood cell count, 25 vs 4 per microliter; P = .15) produced much less pyuria. Pyuria with a white blood cell count greater than 10 per microliter (>5 per high-power field in a conventional urinalysis) had a specificity of 90% for predicting CAUTI with greater than 10(5) colony-forming units per milliliter but a sensitivity of only 37%. CONCLUSIONS In patients with short-term indwelling urinary catheters, pyuria is less strongly correlated with CAUTI than in noncatheterized patients with urinary tract infection. The strongest association is with CAUTI caused by gram-negative bacilli; the association is far weaker for infections caused by gram-positive cocci or yeasts. Most patients with CAUTI are asymptomatic and do not have associated fever. Pyuria should not be used as the sole criterion to obtain a urine culture in a patient with a catheter.
Equivocations, Exponents, and Second-Order Coding Rates Under Various Rényi Information Measures

We evaluate the asymptotics of equivocations, their exponents as well as their second-order coding rates under various Rényi information measures. Specifically, we consider the effect of applying a hash function on a source and we quantify the level of non-uniformity and dependence of the compressed source from another correlated source when the number of copies of the sources is large. Unlike previous works that use Shannon information measures to quantify randomness, information, or uniformity, we define our security measures in terms of a more general class of information measures—the Rényi information measures and their Gallager-type counterparts. A special case of these Rényi information measure is the class of Shannon information measures. We prove tight asymptotic results for the security measures and their exponential rates of decay. We also prove bounds on the second-order asymptotics and show that these bounds match when the magnitudes of the second-order coding rates are large. We do so by establishing new classes non-asymptotic bounds on the equivocation and evaluating these bounds using various probabilistic limit theorems asymptotically.
Gcse, a Novel Germ-Cell-Specific Gene, Is Differentially Expressed During Meiosis and Gametogenesis

Gametogenesis is a complex process wherein germ cells develop from primordial diploid cells into haploid gametes. To understand the mechanisms controlling gametogenesis, we identified a novel germ-cell-specific gene, Gcse. Gcse produces two major transcripts that are 1589 bp (Gcse-l) and 906 bp (Gcse-s) in length. Northern blotting and reverse transcription–polymerase chain reaction (RT-PCR) analyses of multiple tissues reveal that Gcse-l is expressed in both adult testes and ovaries, but Gcse-s is expressed only in adult testes. During female gonad development, Gcse-l is expressed from embryonic day 13.5 to adulthood, specifically in oocytes, and maintained in ovulated and fertilized eggs. However, Gcse-s signals were detected only in ovulated oocytes and fertilized eggs but not in adult ovary. During male gonad development, strong Gcse-l signals were detected in late pachytene spermatocytes and round spermatids. However, Gcse-s transcripts exist only in round spermatids. Furthermore, the expression of GCSE-L proteins and their subcellular localizations within cells are stage specific. GCSE-L is detected in the nucleus of late pachytene spermatocytes. During meiosis, GCSE-L is translocated to acrosome regions in spermatids and maintained in the acrosome of spermatozoa. GCSE-L colocalizes with acrosin and lectin peanut agglutinin in the Golgi apparatus. However, GCSE-S proteins are expressed only in the nucleus of spermatids. From these results, we suggest that GCSE proteins play roles in meiosis and may be involved in acrosome biogenesis during spermiogenesis.
Empirically-Derived MCMI-III Personality Profiles of Incarcerated Female Substance Abusers

Abstract Previous research suggests that male, alcohol, and drug-dependent subjects fall into distinct personality clusters (e.g., schizoid, narcissistic, antisocial). However, few studies utilizing cluster analyses have been conducted with females who are incarcerated or substance dependent. In the present study, the Millon Clinical Multiaxial Inventory-III (MCMI-III) was administered to 210 female inmates in a jail-based substance abuse prevention program. Hierarchical Cluster Analysis with Varimax rotation resulted in the following three cluster profiles: “normal” (no significant elevations), narcissistic, and antisocial. Hypotheses regarding the personality structure of incarcerated female substance abusers are offered; clinical implications of the findings are discussed.
Learning the Consistent Behavior of Common Users for Target Node Prediction across Social Networks

We study the target node prediction problem: given two social networks, identify those nodes/users from one network (called the source network) who are likely to join another (called the target network, with nodes called target nodes). Although this problem can be solved using existing techniques in the field of cross domain classification, we observe that in many realworld situations the cross-domain classifiers perform sub-optimally due to the heterogeneity between source and target networks that prevents the knowledge from being transferred. In this paper, we propose learning the consistent behavior of common users to help the knowledge transfer. We first present the Consistent Incidence Co-Factorization (CICF) for identifying the consistent users, i.e., common users that behave consistently across networks. Then we introduce the Domain-UnBiased (DUB) classifiers that transfer knowledge only through those consistent users. Extensive experiments are conducted and the results show that our proposal copes with heterogeneity and improves prediction accuracy.
Steering nonholonomic systems using sinusoids

Methods for steering systems with nonholonomic constraints between arbitrary configurations are investigated. R.W. Brockett (1981) derived the optimal controls for a set of canonical systems in which the tangent space to the configuration manifold is spanned by the input vector fields and their (first-order) Lie brackets. Using Brockett's result as motivation, the authors derive suboptimal trajectories for systems which are not in canonical form and consider systems in which it takes more than one level of bracketing to achieve controllability. These trajectories use sinusoids at integrally related frequencies to achieve motion at a given bracketing level. Examples and simulation results are presented. <<ETX>>
Furchtreduktion durch wiederholte Reizkonfrontation bei Spezifischer Phobie vom Tier-Typus

Zusammenfassung. Theoretischer Hintergrund: Habituation phobischer Furcht wird haufig als zentraler Wirkmechanismus von Konfrontationsbehandlung angesehen. Neurobiologische Modelle der Furchtreduktion gehen jedoch davon aus, dass fur das Verlernen von Furcht komplexere Interaktionen zwischen subkortikalen Affektzentren und frontalen kortikalen Strukturen erforderlich sind. Fragestellung: Ziel der vorliegenden Studie war daher die Untersuchung des Verlaufs der Furchtreduktion bei wiederholter Konfrontation von Phobie-relevanten Reizen bei Spinnen/Schlangen-Phobikern (n = 16) im Vergleich zu einer entsprechenden Kontrollgruppe (n = 16). Methode: Gemessen wurden Hautleitwertreaktionen sowie die Grose der Schreckreaktionen, die beim wiederholten Betrachten Phobie-relevanter im Vergleich zu neutralen Bildern ausgelost wurden. Ergebnisse: Die Schreckreaktionen der Phobiker waren wahrend des Betrachtens Phobie-relevanter Reize deutlich potenziert im Vergleich zu neutralen Bildinhalten. Diese Potenzierung blieb w.
Effect of milk on fibronectin and collagen type I binding to Staphylococcus aureus and coagulase-negative staphylococci isolated from bovine mastitis

Tryptic soy broth (TSB)-grown cells of Staphylococcus aureus isolated from acute and chronic bovine mastitis bound mainly 125I-fibronectin (Fn) [corrected], whereas strains of nine species of coagulase-negative staphylococci showed a predominant interaction with 125I-collagen (Cn) [corrected] type I. A particle agglutination assay (PAA) was used to examine the interaction of coagulase-negative staphylococci with 125I-Fn and 125I-Cn immobilized on latex. All 368 coagulase-negative staphylococci demonstrated high 125I-Cn and moderate to low 125I-Fn interactions in the PAA. Cn-PAA reactivity was high among strains of Staphylococcus xylosus (84.2%), Staphylococcus simulans (77.8%), Staphylococcus epidermidis (76.7%), and Staphylococcus hyicus (74.3%), whereas all six Staphylococcus capitis strains clumped Cn-PAA reagent. Incubating TSB-grown cells in 10% skim milk for 1 h decreased the 125I-Fn- and 125I-Cn-binding affinity in most of the S. aureus and coagulase-negative staphylococci, while growth in 10% skim milk for 18 h resulted in more than 90% decrease or complete loss of interaction with these proteins. Decreased 125I-Fn binding in the presence of milk was correlated with protease production but not with 125I-Cn binding.
Effects of the Social Origins of Alliances on Alliance Performance

This research responds to the charges of two criticisms about the embeddedness approach—(1) that it does not treat embeddedness as a variable and (2) that it does not explain economic performance—by investigating how variations in the social origins of alliances account for alliance performance. The hypotheses of this research state that the strength of ties between individuals who initiate alliance formation processes is positively related to alliance performance, because such ties eliminate the uncertainty that firms face when forming alliances, reduce the likelihood of partners’ malfeasance, and facilitate information exchange for sharing tacit knowledge. However, analysis of the mail survey data on biopharmaceutical R&D alliances indicates that such a simple association does not exist. Rather, one possible interpretation of the findings is that the activation of strong ties in forming alliances seems to be a double-edged sword that not only creates an opportunity for building successful alliances but also restricts the ability of organizations to acquire heterogeneous information and cutting-edge knowledge.
Collective Security and the Demand for Legal Handguns

One controversial element in the debate on firearms policy is whether crime and civil disorders contribute significantly to the private demand for firearms. In this paper we present a model to explain legal handgum demand that emphasizes the level of collective security as a key factor. Time-series data on legal gun demand in Detroit from 1951 to 1977 are consistent with a model in which individuals respond to three determinants of collective security: high violent crime rates, civil disordes, and police strength. The analysis suggests that low confidence in collective security contributes to both the need for and the resistance to gun control policies.
Relation between indicators for quality of occupational rehabilitation of employees with low back pain.

OBJECTIVES: To assess if the implementation of guidelines for occupational rehabilitation of patients with low back pain by means of process variables--a set of objective criteria for technical performance and continuity of care--led to a better outcome in clinical and return to work variables. METHODS: The study group consisted of 59 patients with at least 10 days of sick leave because of low back pain. Univariate analyses as well as multiple logistic regression and Cox's regression analyses were performed to assess the relation between quality of care and outcome. RESULTS: Process indicators for technical competence, continuity of care, and total performance were all significantly related to satisfaction of employees. Continuity of care and total performance were significantly related to working status at 3 months, and time to return to work. None of the process indicators was related to pain or disability after 3 months follow up. Satisfaction was not related to any of the other outcome variables. This indicates that if guidelines for occupational rehabilitation are met, outcome is better. CONCLUSION: Quality of the process of care was related to outcome. Interventions of occupational physicians need improvement in the areas of continuity of care and communication with treating physicians. The effectiveness of an improved intervention should be studied in a subsequent randomised clinical trial.
Efficacy and safety of autologous cell therapies for knee cartilage defects (autologous stem cells, chondrocytes or the two): randomized controlled trial design.

AIM The main aim of this trial is to test the safety and efficacy of autologous stromal/stem cells, chondrocytes or the two combined in the treatment of knee cartilage defects. PATIENTS & METHODS Patients with symptomatic chondral/osteochondral defects will be randomized to cell therapy treatment with one of three cell populations (1:1:1). The primary efficacy outcome is a functional knee score (Lysholm) at 15 months post-treatment and the primary safety outcome is the incidence of adverse events. Secondary objectives are to analyze repair tissues, quality of life and cost-utility assessments. Exploratory objectives are to identify predictors for success/potency and dose-response relationships. RESULTS & CONCLUSION This trial has been carefully designed so that valuable scientific and clinical information can be gathered throughout and in the final analysis.
Equidistant Categorical Labels for Construction of Likert-Type Scales

Though Likert-type scales are frequently employed in research, typically little systematic consideration is given to the process of identifying the number of response categories, selecting appropriate category labels or ensuring that the scale yields an acceptable level of measurement. Relatively little research has been performed to identify the category labels which yield scales with equidistant category points. Unidimensional ratings of category labels associated with the psychological dimensions of intensity, frequency, and similarity on 5-, 7-, and 9-point scales by 192 introductory psychology students yielded several scales with equidistant intervals. Researchers are encouraged to employ such Likert-type scales with interval levels of measurement and to validate them on the population being studied.
Towards an Application of Update Propagation on Logic Programs Representing Java Source Code

Logic programs are now used as a representation of object-oriented source code in academic prototypes for about a decade. This representation allows a clear and concise implementation of analyses of the object-oriented source code. The full potential of this approach is far from being explored. In this paper, we report about an application of the well-established theory of update propagation within logic programs. Given the representation of the object-oriented code as facts in a logic program, a change to the code corresponds to an update of these facts. We demonstrate how update propagation provides a generic way to generate incremental versions of such analyses.
