Gender and entrepreneurship

Purpose – Women‐owned businesses are frequently described as under‐performing in that the majority remain small and marginal. The authors dispute this description; within this paper, it is argued that such performance profiles reflect the constrained performance of most small firms. The assertion that women owned firms under‐perform reflects a gendered bias within the entrepreneurial discourse where femininity and deficit are deemed coterminous. In addition, women‐owned firms are expected to under‐perform given expectations of female weakness in the context of male normativity and superiority. Accordingly, the aim of this paper is to critically evaluate the association between gender and business performance suggesting that this critique has implications for the broader development of our understanding of entrepreneuring behaviours.Design/methodology/approach – This is a conceptual research note which explores the notion of performance and under‐performance in the context of gender.Findings – It is argued.
Helping HPC Users Specify Job Memory Requirements via Machine Learning

Resource allocation in High Performance Computing (HPC) settings is still not easy for end-users due to the wide variety of application and environment configuration options. Users have difficulties to estimate the number of processors and amount of memory required by their jobs, select the queue and partition, and estimate when job output will be available to plan for next experiments. Apart from wasting infrastructure resources by making wrong allocation decisions, overall user response time can also be negatively impacted. Techniques that exploit batch scheduler systems to predict waiting time and runtime of user jobs have already been proposed. However, we observed that such techniques are not suitable for predicting job memory usage. In this paper we introduce a tool to help users predict their memory requirements using machine learning. We describe the integration of the tool with a batch scheduler system, discuss how batch scheduler log data can be exploited to generate memory usage predictions through machine learning, and present results of two production systems containing thousands of jobs.
Condominium and the City: The Rise of Property in Vancouver

Condominium is a form of land ownership that combines private ownership of an individual unit in a multi-unit building with an undivided share of the common property in the building and a right to participate in the collective governance of the private and common property. Introduced by statute across North America in the 1960s, condominium facilitated the vertical subdivision of land and enabled a massive increase in the density of private interests. This article describes condominium and considers the justifications that were offered for this rearrangement of property. It then chronicles the introduction of condominium to the city of Vancouver and maps its spread across the city from 1970 to 2010. In doing so, the article reveals that condominium, a legal innovation without peer in its capacity to increase the density of private ownership in land, has provided the legal architecture of ownership for the remaking of Vancouver.
A multi-objective evolutionary method for Dynamic Airspace Re-sectorization using sectors clipping and similarities

Dynamic Airspace Sectorization (DAS) is a future concept in Air Traffic Management. Its main goal is to increase airspace capacity by reshaping - thus optimizing - airspace sector boundaries based on the specifics of different air traffic situations, weather conditions and other factors. The primary objective for the optimization is to balance and reduce the workload of Air Traffic Controllers (ATCs). Many researchers have made efforts in this topic in the past years. However, air traffic changes continually, and DAS has to be adaptive to each change; be it in terms of aircraft density, dynamic routes, fleet mix, etc. Therefore, instead of sectorizing the airspace each time a change occurs, we should re-sectorize it by maintaining maximum similarities between each sectorization. In this paper, we propose a multi-objective evolutionary computation methodology to re-sectorize an airspace. We use a similarity measure between the existing sectorization and the re-sectorization as an objective to maximize during the evolution.We test the methodology with different air traffic conditions with four objective functions: minimize ATC task load standard deviation, maximize average flight sector time, maximize the minimum distance between traffic crossing points and sector boundaries, and maximize the similarity of two airspace sectorizations. Experimental results show that our re-sectorization method is able to perform airspace re-sectorization under different changes in the air traffic, while satisfying the predefined objectives.

Diagnostic accuracy and reading time to detect intracranial aneurysms on MR angiography using a computer-aided diagnosis system.

OBJECTIVE The objective of our study was to determine whether the use of a computer-aided diagnosis (CAD) system can shorten the reading time while maintaining the diagnostic performance of MR angiography for the detection of intracranial aneurysms. MATERIALS AND METHODS Fifty maximum-intensity-projection MR angiograms in 50 patients (16 intracranial aneurysms and 34 negative cases) were used for this observer performance study. Sixteen radiologists--eight neuroradiologists and eight less experienced radiologists--participated in the observer studies and interpreted the MR angiograms without and with CAD output images using an independent test method. The reading times without and with CAD were compared separately for the aneurysm and negative cases. The observers' performances were evaluated using receiver operating characteristic (ROC) analysis. We analyzed separately the data obtained from neuroradiologists and from less experienced radiologists. RESULTS For all observers, the mean area under the ROC curve (Az) with CAD was improved compared with that without CAD (0.903 vs 0.851, respectively; p = 0.109), and the mean reading time per case was reduced significantly by 18.1 seconds (28.5%) (from 63.4 to 45.3 seconds, p < 0.05). When CAD output images were available, the mean A(z) for the less experienced radiologists was significantly improved (0.911 vs 0.787, p < 0.05), but not for the neuroradiologists. The mean reading time of the less experienced radiologists with CAD was significantly shorter than that of the neuroradiologists without CAD (39.8 vs 54.5 seconds, p < 0.05). CONCLUSION The use of a CAD system for the detection of intracranial aneurysms on MR angiography can shorten the reading time while improving diagnostic performance for less experienced radiologists.
A Corpus-based Stylistic Analysis of Body-Soul and Heaviness-Lightness Metaphors in Kundera's Novel The Unbearable Lightness of Being

This paper represents an attempt to conduct a corpus-based stylistic analysis of two conceptual metaphors in The Unbearable Lightness of Being , which is a novel written by Milan Kundera. Soul-body and lightness-heaviness metaphors are foregrounded as being central themes all through the novel. The way such metaphors are used in the novel indicates an insightful employment of metaphor as a cognitive tool which empowers language users with a capacity of conceptualizing different experiences. The researcher adopts conceptual metaphor theory to produce a sort of conceptual analysis incorporating Leech's semantic componential analysis within the overall analytic procedure. Different techniques are figured out in relation to the creative ways of manipulating the cognitive level of language, such as conceptual switching , conceptual extension , and conceptual fusion . These creative techniques are carefully used in the novel under investigation with different ranges of metaphorical creativity. Conceptual switching might be simple but very active in deviating from the conventional conceptual system. Conceptual extension marks certain minute elaborations conventional metaphors undergo extending the limits of cognitive conceptualization. As for conceptual fusion, it proves to be interestingly powerful in producing certain aggregations of metaphorical mappings.

Perceptions of an organization's culture for work and family

Purpose – This study sets out to examine whether proteges have more favorable perceptions of an organization's culture for balancing work and family than non‐proteges.Design/methodology/approach – Data were obtained from 418 employees of a major public accounting firm who completed a survey on mentoring and work‐family issues. Correlation analyses, t‐tests, and regressions were performed to test the hypotheses.Findings – The results strongly support the view that proteges had more favorable perceptions than non‐proteges of the organization's work‐family culture – the degree to which integration of employees' work and family lives is supported. Having a mentor was significantly related to each component of work‐family culture (managerial support, time demands, and career consequences) in the predicted direction.Research limitations/implications – By focusing on respondents in a single firm, it is impossible to determine whether the findings generalize to individuals in other industries or companies.Practic.
Prática regular de atividade física e sedentarismo: influência na qualidade de vida de idosas

The study aims to compare the Quality of Life (QV) of female elderly practicing regular physical activity and sedentary female elderly in the physical, psychological, social and environmental domains. This is a descriptive, observational and cross study. The Mini Mental State Examination (Folstein, FOLSTEIN and MCHUG, 1975; BERTOLUCCI et al, 1994) was applied, including the illiterate who had scores above 18 and the literate with scores above 14.The sample was divided into two groups: Physical Activity Group (AF), 16 female elderly, practicing regular physical activity, sedentary group (SE), 15 sedentary female elderly. An identification questionnaire and quality of life questionnaire WHOQOL-bref (FLECK, 2000) was applied. The average age was 70.8 (± 7) years in the AF group and 69.7 (± 6.2) years in SE group. In WHOQOL-bref, the average scores of the AF and SE groups and were, respectively: 74.8 (± 12.9) and 60.2 (± 20.2) in the physical domain; 68.8 (± 11.6) and 60,8 (± 20.9) in the psychological; 78.1 (± 10) and 66.1 (± 22.2) in the social; 66.8 (± 11.5) and 57.5 (± 15.4) in the environmental domain. The regular practice of physical activity provided in the AF group higher scores in the WHOQOL-bref, with statistically significant differences in social (p = 0.050) and environmental (p = 0.047) when compared to SE group. In the physical domain, the AF group showed difference (p = 0.054) but not statistically significant. These results allow us to conclude that the active lifestyle adopted by the female elderly practitioners of regular physical activity was able to improve QL of them, compared with the sedentary female elderly.
Formation and Decay of Hydroperoxo-Ferric Heme Complex in Horseradish Peroxidase Studied by Cryoradiolysis*

Using radiolytic reduction of the oxy-ferrous horseradish peroxidase (HRP) at 77 K, we observed the formation and decay of the putative intermediate, the hydroperoxo-ferric heme complex, often called “Compound 0. ” This intermediate is common for several different enzyme systems as the precursor of the Compound I (ferryl-oxo π-cation radical) intermediate. EPR and UV-visible absorption spectra show that protonation of the primary intermediate of radiolytic reduction, the peroxo-ferric complex, to form the hydroperoxo-ferric complex is completed only after annealing at temperatures 150–180 K. After further annealing at 195–205 K, this complex directly transforms to ferric HRP without any observable intervening species. The lack of Compound I formation is explained by inability of the enzyme to deliver the second proton to the distal oxygen atom of hydroperoxide ligand, shown to be necessary for dioxygen bond heterolysis on the “oxidase pathway,” which is non-physiological for HRP. Alternatively, the physiological substrate H2O2 brings both protons to the active site of HRP, and Compound I is subsequently formed via rearrangement of the proton from the proximal to the distal oxygen atom of the bound peroxide.
A Particle Swarm Optimizer with Multi-stage Linearly-Decreasing Inertia Weight

The inertia weight is often used to control the global exploration and local exploitation abilities of particle swarm optimizers (PSO). In this paper, a group of strategies with multi-stage linearly-decreasing inertia weight (MLDW) is proposed in order to get better balance between the global and local search. Six most commonly used benchmarks are used to evaluate the MLDW strategies on the performance of PSOs. The results suggest that the PSO with W5 strategy is a good choice for solving unimodal problems due to its fast convergence speed, and the CLPSO with W5 strategy is more suitable for solving multimodal problems. Also, W5-CLPSO can be used as a robust algorithm because it is not sensitive to the complexity of problems for solving.

More specifically, I will examine the effects of both game types and settings on older adults' depression. A between-subject factorial design experiment will be conducted to address the main purpose. Results from the study will contribute to existing literature on the influencing mechanisms of games for depression, and provide practical knowledge of game design for mental health purposes.
Critical factors for high‐performance physically adsorbed (dynamic) polymeric wall coatings for capillary electrophoresis of DNA

Physically adsorbed (dynamic) polymeric wall coatings for microchannel electrophoresis have distinct advantages over covalently linked coatings. In order to determine the critical factors that control the formation of dynamic wall coatings, we have created a set of model polymers and copolymers based on N,N‐dimethylacrylamide (DMA) and N,N‐diethylacrylamide (DEA), and studied their adsorption behavior from aqueous solution as well as their performance for microchannel electrophoresis of DNA. This study is revealing in terms of the polymer properties that help create an “ideal” wall coating. Our measurements indicate that the chemical nature of the coating polymer strongly impacts its electroosmotic flow (EOF) suppression capabilities. Additionally, we find that a critical polymer chain length is required for polymers of this type to perform effectively as microchannel wall coatings. The effective mobilities of double‐stranded (dsDNA) fragments within dynamically coated capillaries were determined in order to correlate polymer hydrophobicity with separation performance. Even for dsDNA, which is not expected to be a strongly adsorbing analyte, wall coating hydrophobicity has a deleterious influence on separation performance.
Examining the Link between Biofilm Formation and the Ability of Pathogenic Salmonella Strains to Colonize Multiple Host Species

Salmonella are important pathogens worldwide and a predominant number of human infections are zoonotic in nature. The ability of strains to form biofilms, which is a multicellular behavior characterized by the aggregation of cells, is predicted to be a conserved strategy for increased persistence and survival. It may also contribute to the increasing number of infections caused by ingestion of contaminated fruits and vegetables. There is a correlation between biofilm formation and the ability of strains to colonize and replicate within the intestines of multiple host species. These strains predominantly cause localized gastroenteritis infections in humans. In contrast, there are salmonellae that cause systemic, disseminated infections in a select few host species; these “invasive” strains have a narrowed host range, and most are unable to form biofilms. This includes host-restricted Salmonella serovar Typhi, which are only able to infect humans, and atypical gastroenteritis strains associated with the opportunistic infection of immunocompromised patients. From the perspective of transmission, biofilm formation is advantageous for ensuring pathogen survival in the environment. However, from an infection point of view, biofilm formation may be an anti-virulence trait. We do not know if the capacity to form biofilms prevents a strain from accessing the systemic compartments within the host or if loss of the biofilm phenotype reflects a change in a strain’s interaction with the host. In this review, we examine the connections between biofilm formation, Salmonella disease states, degrees of host adaptation, and how this might relate to different transmission patterns. A better understanding of the dynamic lifecycle of Salmonella will allow us to reduce the burden of livestock and human infections caused by these important pathogens.
Quality of Distance Education in Turkey: Preschool Teacher Training Case.

Distance education is used for teacher training at different levels and fields in Turkey. Launched in the 2000-2001 academic year and still applied by Anadolu University, the Pre-School Teacher Training Program is one of those programs offered by distance education. This study aims to evaluate Anadolu University’s Preschool Teacher Training Program in Turkey by obtaining student opinions. A total of 1,026 senior students enrolled in the Preschool Education major at the Open Education Faculty of Anadolu University participated in the survey. A questionnaire to determine the opinions of students on the program was used as a means of data collection. Means (X) and standard deviations (SD) were employed to analyze the survey data. The results showed that although the teacher candidates study at a good level, they do not have a good record of watching the television programs. The results also revealed that the opinions of teacher candidates about the textbooks, television programs, teaching practices, and academic assistance services are positive.
Extending workflow patterns with transactional dependencies to define reliable composite Web services

In this paper, we introduce the concept of a transactional pattern for specifying flexible and reliable composite Web services. A transactional pattern is a convergence concept between workflow patterns and advanced transactional models; thus it combines workflow flexibility and transaction reliability. Designers can simply connect together transactional patterns to define a composite Web service. In relation, we provide techniques to ensure control and transactional consistency of such services.
Successive and cyclic oral contraceptive pill pretreatment improves IVF/ICSI outcomes of PCOS patients and ameliorates hyperandrogenism and antral follicle excess

Abstract Objectives: To evaluate different oral contraceptive pill (OCP) pretreatment associated differential in-vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI) outcomes of polycystic ovary syndrome (PCOS) patients and explore enhanced hormonal balance induced by the pretreatment. Methods: This retrospective study included 500 PCOS women and 565 normal ovulating counterparts undergoing IVF/ICSI. The PCOS patients were divided into three groups based on the OCP pretreatment regimens: non-OCP (without OCP pretreatment), unsuccessive OCP (the period of successive pretreatment ≤2 months) and successive OCP (the period of successive pretreatment ≥3 months) groups. Comprehensive hormonal and ultra-sonographic assessments were performed before/after IVF pretreatment. Confounding factors affecting pregnancy outcomes were analyzed with logistic regression. Results: PCOS patients with significant endocrine disorders had reduced implantation and pregnancy rates and increased miscarriage rate. Successive, not unsuccessive OCP pretreatment, significantly improved the implantation and pregnancy rates, and reduced the incidence of monotocous small-for-gestational age infants, which was accompanied by remarkably decreased hyperandrogenism and antral follicles. Conclusion: PCOS is an independent risk factor for poor IVF outcome. Successive, not unsuccessive, OCP cyclical pretreatment could improve pregnancy outcome of PCOS patients, associated with reduction of hyperandrogenism and antral follicle excess.

Role of Fractalkine/CX3CL1 and Its Receptor in the Pathogenesis of Inflammatory and Malignant Diseases with Emphasis on B Cell Malignancies

Fractalkine/CX3CL1, the only member of the CX3C chemokine family, exists as a membrane-anchored molecule as well as in soluble form, each mediating different biological activities. It is constitutively expressed in many hematopoietic and nonhematopoietic tissues such as endothelial and epithelial cells, lymphocytes, neurons, microglial osteoblasts. The biological activities of CX3CL1 are mediated by CX3CR1, that is expressed on different cell types such as NK cells, CD14+ monocytes, cytotoxic effector T cells, B cells, neurons, microglia, smooth muscle cells, and tumor cells. The CX3CL1/CX3CR1 axis is involved in the pathogenesis of several inflammatory cancer including various B cell malignancies. In tumors the interaction between cancer cells and cellular microenvironment creates a context that may promote tumor growth, increase tumor survival, and facilitate metastasis. Therefore the role of the CX3CL1/CX3CR1 has attracted interest as to the development of potential therapeutic approaches. Here we review the different effects of the CX3CL1/CX3CR1 axis in several inflammatory and neurodegenerative diseases and in cancer, with emphasis on human B cell lymphomas.
