Authors: Nikina Anna , Shelton Lois M. , LeLoarne Séverine 
Published: February 2015

Purpose– The purpose of this paper is to explore: How do changes in the role of the husband affect the marriage of a woman entrepreneur? How do changes in the marriage affect the woman entrepreneur and her relationship with her business?Design/methodology/approach– A novel theoretical approach based on marriage contract theory, gender role ideology and psychological contracts was used. Qualitative methodology included analysis of multiple cases based on rich interview data gathered from 12 Scandinavian couples.Findings– Research revealed that the pattern of dominance between the husband and wife, the gender role ideologies of the two spouses, and the interaction between this pattern and the gender role ideologies, and overall level of marital harmony were key determinants of husbands’ spousal support.Research limitations/implications– Sample size and geographical limitations. Future research: exploring other cultural settings, further application of marriage and psychological contracts in female entrepreneurship; studies of the impact areas of the husband in the wife’s business – also from the perspective of implicit contracts.Practical implications– Research sheds light on how women run their businesses and how the changing roles of the spouse alter marriage dynamics and influence the wife-business relationship.Social implications– Findings benefit female entrepreneurs considering the launch of a business, couples in which the wife currently owns a business, state and governmental policymakers, business consultants, and entrepreneurship instructors. These findings can help couples better prepare for the demands of entrepreneurship.Originality/value– For scholars: expanded understanding of the work-family interface of female entrepreneurs via novel theoretical approach. For business practitioners: understanding the impact of a spouse on life and career of female entrepreneur.

AbstractObjectiveBecause the one‐handed chest compression (OHCC) technique uses one hand, unlike the two‐handed chest compression (THCC) technique, compression depth might be reduced more rapidly in OHCC than THCC. The present study was conducted to determine whether compression depth was affected within 2 min after the start of OHCC in a simulated in‐hospital paediatric arrest model.MethodsForty medical doctors performed continuous OHCC on a child manikin lying on a hard floor using a CPRmeter for 2 min. The hand used to perform the OHCC technique was randomised to the right or left hand. The mean compression depth (MCD) and the mean compression rate (MCR) were calculated at 30 s intervals using the Q‐CPR review software.ResultsMCD values decreased significantly with time (0–30 s: 44.3 ± 4.1 mm, 30–60 s: 42.4 ± 4.9 mm, 60–90 s: 40.5 ± 5.8 mm, and 90–120 s: 38.7 ± 5.7 mm; P < 0.001). The MCR also tended to decrease with time (0–30 s: 119.3 ± 12.5/min, 30–60 s: 119.0 ± 13.1/min, 60–90 s: 117.9 ± 14.5/min, 90–120 s: 117.8 ± 14.9/min), and the differences were statistically significant between 30–60 s and 60–90 s (P = 0.037) and between 30–60 s and 90–120 s (P = 0.043).ConclusionsCompression depth was decreased significantly from 30 s onwards after starting the OHCC technique using a simulated paediatric arrest model. The results of the present study suggest that future strategies should be established to prevent a decrease in compression depth within 1 min during OHCC.

AimsThe purpose of this study was to investigate the potential roles of pathological variables in the prediction of nodal metastasis in women with endometrioid endometrial cancer (EC).Materials and MethodsWomen who underwent surgery for endometrioid EC between 1995 and 2012 were retrospectively reviewed. Those who underwent prior neoadjuvant chemotherapy or radiotherapy and inadequate lymphadenectomy as well as those with nonendometrioid histology, synchronous cancers, International Federation of Gynecology and Obstetrics stage IV disease, gross uterine serosal and/or gross adnexal involvement were excluded. Lymph node dissemination was defined as occurring in the following circumstances: (i) when nodal metastasis with pelvic and/or para‐aortic (P/PA) lymph node dissection (LND) was performed or (ii) when there was recurrence in the P/PA lymph nodes after a negative LND or when LND was not performed. Univariate and multivariate logistic regression models were used to identify the pathological predictors of lymphatic dissemination.ResultsA total of 827 women with endometrioid EC were assessed; 516 (62.4%) of whom underwent P/PA LND and 205 (24.8%) underwent P LND. Sixty‐seven (13%) women in the P/PA LND group and 5 (2.4%) in the P LND group had positive lymph nodes. Multivariate analysis confirmed cervical stromal invasion (OR 4.04, 95% CI 2.02–8.07 (P < 0.001)) and lymphovascular space invasion (LVSI) (OR 110.18, 95% CI 38.43–315.87 (P < 0.001)) as independent predictors of lymphatic dissemination.ConclusionCervical stromal invasion and LVSI are highly associated with LN metastasis. These markers may serve as a surrogate for nodal metastasis.

AbstractObjectiveThis study aims to compare survival from breast, colon, lung, ovarian and rectal cancer by geographical remoteness in New South Wales (NSW).DesignRetrospective population‐wide registry study.SettingNSW, Australia.ParticipantsA total of 107 060 NSW residents, who were diagnosed with any of the five cancers between 01 January 2000 and 31 December 2008.Main outcome measuresKaplan–Meier survival curves and proportional hazards regression were used to compare survival by geographical remoteness of residence at diagnosis, controlling for gender, age and extent of disease at diagnosis. Remoteness was classified using standard definitions: major city, inner regional (InnReg), outer regional (OutReg) and remote (including very remote).ResultsSignificant differences in survival (likelihood of death) were identified in all five cancers: breast (adjusted hazard ratio(HR) = 1.22 (95% confidence interval (CI), 1.001–1.48) in regionalised and HR = 1.30 (1.02–1.64) in metastatic disease for OutReg areas); colon (HR = 1.14 (1.01–1.29) for OutReg areas in metastatic disease); lung (HR range = 1.08–1.35 (1.01–1.48) for most non‐metropolitan areas in all stages of disease excepting regionalised); ovarian (HR = 1.32 (1.06–1.65) for OutReg areas in metastatic disease, HR = 1.40 (1.04–1.90) for InnReg areas and HR = 1.68 (1.02–2.77) for OutReg areas in unknown stage of disease) and rectal (HR = 1.37 (1.05–1.78) for OutReg areas in localised and HR = 1.14 (1.002–1.30) for InnReg areas in regionalised disease). Where significant differences were found, major cities tended to show the best survival, whereas OutReg areas tended to show the worst. Although no definitive interpretation could be made regarding remote areas due to small patient numbers, their survival appeared relatively favourable.ConclusionsReasons that contribute to the differences observed and the disparate results between cancer types need to be further explored in order to facilitate targeted solutions in reducing survival inequality between NSW regions.
A web‐based peer‐assessment approach to improving junior high school students' performance, self‐efficacy and motivation in performing arts courses

Published: February 2015

AbstractIn this paper, a web‐based peer‐assessment approach is proposed for conducting performing arts activities. A peer‐assessment system was implemented and applied to a junior high school performing arts course to evaluate the effectiveness of the proposed approach. A total of 163 junior high students were assigned to an experimental group and a control group. The students in the experimental group learned with the web‐based peer‐assessment approach, whereas those in the control group learned with a web‐based streaming video‐supported environment. The experimental results showed that, in comparison with the web‐based streaming video‐supported learning approach, the web‐based peer assessment approach could significantly improve the students' performance, self‐efficacy and motivation in the performing arts course. In the meantime, it was found that the peer assessment ratings were highly correlated with the teachers' ratings in every performance item; moreover, the performance ratings were highly related to the students' self‐efficacy in evaluating peers' work and improving their own work based on peers' comments as well as their intrinsic motivation, showing the effectiveness of the performance scoring rubrics and the peer assessment approach. The satisfaction questionnaire results also revealed that the students who learned with the peer assessment approach were significantly more satisfied with the learning activity than those who learned with the web‐based learning approach.
Effects of concept map extraction and a test‐based diagnostic environment on learning achievement and learners' perceptions

AbstractComputerised testing and diagnostics are critical challenges within an e‐learning environment, where the learners can assess their learning performance through tests. However, a test result based on only a single score is insufficient information to provide a full picture of learning performance. In addition, because test results implicitly include information about the underlying subject concepts and their relationships to each other, this paper proposes a more effective method for analysing test results by providing a concept map (CM) to facilitate learners' understanding of their learning performance. An innovative approach, not explored in previous studies, is proposed to automatically construct a personalised CM. A CM‐smart extraction and explicit diagnosis (CM‐SEED) learning system has been developed to diagnose learning barriers and misconceptions and to supply relevant suggestions and guidance for remedial learning. This study examined 90 students from two classes at a university and assigned one class to be the experimental group and another class to be the control group. The results indicated that the students who used the CM‐SEED learning system had superior perceptions regarding their learning; furthermore, they accomplished superior learning achievement that displayed statistical significance. Consequently, the study concluded that CM extraction in a test‐based diagnostic environment can lead learners to enhanced learning performance.

SummaryDeubiquitinase enzymes (DUBs) of the proteasomal 19S regulatory particle are emerging as important therapeutic targets in several malignancies. Here we demonstrate that inhibition of two proteasome‐associated DUBs (USP14 and UCHL5) with the small molecule DUB inhibitor b‐AP15, results in apoptosis of human Waldenström macroglobulinaemia (WM) cell lines and primary patient‐derived WM tumour cells. Importantly, b‐AP15 produced proteotoxic stress and apoptosis in WM cells that have acquired resistance to the proteasome inhibitor bortezomib. In silico modelling identified protein residues that were critical for the binding of b‐AP15 with USP14 or UCHL5 and proteasome enzyme activity assays confirmed that b‐AP15 does not affect the proteolytic capabilities of the 20S proteasome β‐subunits. In vitro toxicity from b‐AP15 appeared to result from a build‐up of ubiquitinated proteins and activation of the endoplasmic reticulum stress response in WM cells, an effect that also disrupted the mitochondria. Focused transcriptome profiling of b‐AP15‐treated WM cells revealed modulation of several genes regulating cell stress and NF‐κB signalling, the latter whose protein translocation and downstream target activation was reduced by b‐AP15 in vitro. This is the first report to define the effects and underlying mechanisms associated with inhibition of USP14 and UCHL5 DUB activity in WM tumour cells.
The changing cultural and economic values of wind energy landscapes
Authors: Fast Stewart , Mabee Warren , Blair Jean 
Published: February 2015

We combine a socio‐cultural and economic approach to investigate how wind turbines change the manner in which rural landscapes are valued. Interviews with residents of communities hosting wind projects on the shores of eastern Lake Ontario reveal two main impressions of landscape change: one is to see turbines as irrevocably industrializing and thereby ruining the peace and quiet of rural life and the second downplays visual concerns as negligible. Using photographs as visual aids we find that participants often perceive rural landscapes as devoid of human activity. This is one reason to suspect that cultural celebration of wind technology as part of a new middle landscape is unlikely. Furthermore, our analysis of property value reductions tentatively suggests more frequent than expected reductions for recreational properties and for properties within 2 km to 5 km of turbines but not within 1 km of turbines. We argue the consideration of landscape issues in wind energy approval processes in Ontario is overly narrow and will continue to act as a point of dispute in wind project development.L'évolution des valeurs culturelles et économiques des paysages de l'énergie éolienneÀ partir d'une approche socioculturelle et économique conjuguée, cette étude vise à évaluer dans quelle mesure les éoliennes font évoluer l'appréciation des paysages ruraux. Des entrevues menées auprès de résidents des communautés dans lesquelles les projets éoliens sont déployés sur la rive est du lac Ontario permettent de dresser deux visions de l'évolution du paysage. La première consiste à voir les turbines comme un élément industriel inéluctable qui trouble la paix et la tranquillité de la vie rurale tandis que la seconde minimise l'ampleur des impacts visuels en les qualifiant de négligeables. Le recours à des photographies montre à quel point les participants perçoivent généralement les paysages ruraux comme étant dépourvus d'activité humaine. Il est donc raisonnable de penser qu'il est improbable que la technologie éolienne fasse l'objet d'une appropriation culturelle inscrite dans l'émergence d'un « paysage intermédiaire ». Par ailleurs, une analyse portant sur la dépréciation des valeurs immobilières permet d'avancer, sous toute réserve, que la dépréciation est plus forte que prévu pour les propriétés de villégiature et les propriétés situées dans un rayon de 2 à 5 km des turbines, mais négligeable à moins de 1 km. Nous soutenons que les enjeux paysagers ne sont pas assez pris en compte dans les processus d'approbation des parcs éoliens en Ontario, ce qui occasionnera des litiges dans le développement des projets d'éoliennes.
Exploring the Social Integration of Sexual Minority Youth Across High School Contexts

Published: February 2015

Mental health disparities between sexual minority and other youth have been theorized to result in part from the effects of the stigmatization on social integration. Stochastic actor‐based modeling was applied to complete network data from two high schools in the National Longitudinal Study of Adolescent Health (Mage = 15 years, N = 2,533). Same‐sex attracted youth were socially marginalized in a smaller predominantly White school but not in a larger, more racially diverse school. For both schools, homophily was a critical network feature, and could represent social support for and social segregation of such youth. These findings emphasize the school context in studying the social lives of sexual minority youth and suggest that youth may be better off socially in larger and more diverse schools.
Darwin's hypotheses to explain colonization trends: evidence from a quasi‐natural experiment and a new conceptual model

AbstractAimWe examined fish establishment trends in the aftermath of the connection of two Neotropical freshwater ecoregions. Darwin's conundrum was used to examine whether taxonomic and functional relatedness would explain establishment or whether the establishment of new populations was driven by ecological interactions (Darwin's naturalization hypothesis, DNH) or by shared environmental requirements (adaptation hypothesis, AH).LocationParaná River, south‐eastern South America.MethodsTaxonomic relatedness was investigated using a one‐tailed Fisher exact test, considering all species and monophyletic groups. Functional traits were used to estimate niche dissimilarities among non‐native species and across the entire set of native species, generating distributions that were fitted to exponential or logarithmic curves, based on a new conceptual model.ResultsOf the 213 species from the Lower Paraná River that had the opportunity to reach the Upper Paraná River, 25% – 53 spp. – were successfully established. The ratios of unshared to shared genera for both successful and unsuccessful non‐native species were not different, but 7% of type I error probability for Characiformes and 8% for all species, would favour DNH. Our results indicate that both DNH and AH could explain successes but that DNH was more likely to explain failures in establishment.Main conclusionDarwin's naturalization hypothesis is more likely to explain the non‐native establishment in invasion processes. Both the DNH and AH explain successful colonization, but DNH provided the best explanation for failed non‐native establishments. Non‐native species that were functionally similar to native species (i.e. with similar traits) were more likely to fail, suggesting that biotic resistance was directly linked to ecological similarity. Biotic resistance could be the most important mechanism for explaining establishment or failure of non‐native species. The conceptual model proposed here can be used to predict which non‐native species are least likely to establish, based on the functional traits of species in the native community.
Against Permitted Exploitation in Developing World Research Agreements
Authors: Wenner Danielle M. 
Published: February 2015

AbstractThis paper examines the moral force of exploitation in developing world research agreements. Taking for granted that some clinical research which is conducted in the developing world but funded by developed world sponsors is exploitative, it asks whether a third party would be morally justified in enforcing limits on research agreements in order to ensure more fair and less exploitative outcomes. This question is particularly relevant when such exploitative transactions are entered into voluntarily by all relevant parties, and both research sponsors and host communities benefit from the resulting agreements. I show that defenders of the claim that exploitation ought to be permitted rely on a mischaracterization of certain forms of interference as unjustly paternalistic and two dubious empirical assumptions about the results of regulation. The view I put forward is that by evaluating a system of constraints on international research agreements, rather than individual transaction‐level interference, we can better assess the alternatives to permitting exploitative research agreements.

AbstractSocial bee colonies can allocate their foraging resources over a large spatial scale, but how they allocate foraging on a small scale near the colony is unclear and can have implications for understanding colony decision‐making and the pollination services provided. Using a mass‐foraging stingless bee,Scaptotrigona pectoralis(DallaTorre) (Hymenoptera:Apidae:Meliponini), we show that colonies will forage near their nests and allocate their foraging labor on a very fine spatial scale at an array of food sources placed close to the colony. We counted the foragers that a colony allocated to each of nine feeders containing 1.0, 1.5, or 2.0 M sucrose solution [31, 43, and 55% sucrose (wt/wt), respectively] at distances of 10, 15, and 20 m from the nest. A significantly greater number of foragers (2.6–5.3 fold greater) visited feeders placed 10 vs. 20 m away from the colony. Foraging allocation also corresponded to food quality. At the 10‐m feeders, 4.9‐fold more foragers visited 2.0 M as compared to 1.0 M sucrose feeders. Colony forager allocation thus responded to both differences in food distance and quality even when the travel cost was negligible compared to normal colony foraging distances (10 m vs. an estimated 800–1 710 m). For a nearby floral patch, this could result in unequal floral visitation and pollination.
