Smashing patriarchy with cell phones?

This study problematizes the relationship between ICTs, gender and development, informed by the gap between high ambitions, and disappointing outcomes of ICT-enabled development programmes aiming for women’s empowerment. Using a critical discourse analysis approach, this study scrutinizes the underlying assumptions and interpretations of ‘women’s empowerment’ in the context of two Bangladeshi mobile phone programmes targeting women: the Grameen Village Phone Programme (VPP), and Maya Apa. This study is juxtaposed against Western-centric technofeminist scholarship, which scrutinizes the interplay of gender relations and ICTs, extending technofeminist insights beyond its Western scope. Informed by our analysis, we firstly identify a gap in ICT4D scholarship regarding women’s roles as ICT designers and active users, and therefore recommend more attention to women’s active engagement with ICTs. Second, we advocate for an expansion of technofeminist theory to go beyond the Western lens and recognize this is not normative across cultures and contexts. Last, we highlight the usefulness of low-cost, participatory forms of new digital ICTs to forward women’s empowerment in developing countries. Overall, we argue women’s empowerment is best realized by ICT projects that are local, grassroots, contextualized, and made by and for women

Competition level determines compensatory growth abilities

In many animal taxa, size-selective predation favors fast growth early in life. However, same-aged juveniles can diverge in size due to differences in genotype, environmental conditions, and parental effects and thus may vary in competitive ability. Under food scarcity, competitively inferior juveniles may suffer suppressed growth, whereas under benign conditions, small juveniles may exhibit growth compensation and perform as well as large ones. However, studies testing this while controlling for parental effects are lacking. Here, we hand-raised cichlids, Simochromis pleurospilus, from a wide range of egg sizes and manipulated their size by differential feeding. Afterward, high- and low-ration siblings were kept in groups assigned to either a high- or low-competition environment. We investigated how the degree of competition affected aggressiveness and growth of juveniles with different feeding histories. As predicted, when competition was high, high-ration offspring grew fastest. Interestingly, when competition was weak, low-ration juveniles grew at a similar rate as high-ration ones and many were able to catch up in size. High-ration fish were more aggressive than low-ration ones, and this effect was strongest under high competition. Additionally, in the high-competition environment, received aggression was negatively related to growth, and inflicted aggression correlated positively with the growth of the aggressor. These relationships were absent under low competition. Our findings suggest that the abilities to compensate for early growth depression depend on the prevalent level of competition. Aggression is likely used to monopolize food by juvenile S. pleurospilus; however, when competition is strong, aggression cannot compensate for a size disadvantag

Parenting Goals: Links with Parenting Strategies in Caregivers of Children with Autism Spectrum Disorder

OBJECTIVES: Parenting goals describe the outcomes that parents aim for when interacting with their child. They have received little attention in research with caregivers of children with autism spectrum disorder (ASD). The present study explored different types (dimensions) of parenting goals reported by caregivers of children with ASD, investigated links between these parenting goals and child characteristics, and explored whether parenting goals were linked to reported use of particular parenting strategies. METHODS: Data from 161 caregivers of children with ASD aged 7–18 years revealed two goal dimensions: “Norm Adherence Goals” (i.e. the perceived importance of the child cooperating with the parent, respecting their authority, and behaving well in public); and “Autonomy Support and Relationship Goals” (i.e. the perceived importance of promoting the child’s resilience, wellbeing, and the quality of the parent-child relationship). RESULTS: Parents who reported that norm adherence goals were particularly important to them were more likely to endorse parenting strategies such as setting rules, using rewards, and giving punishments. These parents also reported using less “Accommodation” (e.g. making allowances for their child, being flexible, avoiding triggers). Autonomy support and relationship goals were very strongly endorsed by nearly all parents, and we therefore could not find strong links between the importance of these goals and parenting strategies. CONCLUSION: These findings suggest that parenting goals might be importantly linked to parenting strategies and could be considered in personalizing interventions in clinical practice. Given that parents’ cognitions about their child’s behaviour and their role as parents likely interact with and influence their parenting goals, we argue that future research should investigate parenting goals, cognitions, and behaviours in parallel

Functional kernel estimators of conditional extreme quantiles

We address the estimation of "extreme" conditional quantiles i.e. when their order converges to one as the sample size increases. Conditions on the rate of convergence of their order to one are provided to obtain asymptotically Gaussian distributed kernel estimators. A Weissman-type estimator and kernel estimators of the conditional tail-index are derived, permitting to estimate extreme conditional quantiles of arbitrary order.Comment: arXiv admin note: text overlap with arXiv:1107.226

Does Self-directedness in Learning and Careers Predict the Employability of Low-Qualified Employees?

Employability has become a key element in sustaining successful vocational careers. The role of self-directedness is considered paramount in maintaining one's employability. However, it also requires certain competences on part of employees to invest in learning and career development. This study examines the influence of self-directedness in learning and career of low-qualified employees on their employability. In a follow-up study of 284 low-qualified employees, we find that higher levels of self-directedness in learning and career of employees corresponds with higher chance to be promoted to higher-level job positions (vertical job mobility). However, no relationship was found between different formats of self-directedness and job retention or horizontal job mobility of lower qualified personnel.</p

Aging is associated with an earlier arrival of reflected waves without a distal shift in reflection sites

Background-Despite pronounced increases in central pulse wave velocity (PWV) with aging, reflected wave transit time (RWTT), traditionally defined as the timing of the inflection point (T-INF) in the central pressure waveform, does not appreciably decrease, leading to the controversial proposition of a "distal-shift" of reflection sites. T-INF, however, is exceptionally prone to measurement error and is also affected by ejection pattern and not only by wave reflection. We assessed whether RWTT, assessed by advanced pressure-flow analysis, demonstrates the expected decline with aging. Methods and Results-We studied a sample of unselected adults without cardiovascular disease (n=48; median age 48 years) and a clinical population of older adults with suspected/established cardiovascular disease (n=164; 61 years). We measured central pressure and flow with carotid tonometry and phase-contrast MRI, respectively. We assessed RWTT using wave-separation analysis (RWTTWSA) and partially distributed tube-load (TL) modeling (RWTTTL). Consistent with previous reports, T-INF did not appreciably decrease with age despite pronounced increases in PWV in both populations. However, aging was associated with pronounced decreases in RWTTWSA (general population -15.0 ms/decade, P<0.001; clinical population -9.07 ms/decade, P=0.003) and RWTTTL (general -15.8 ms/decade, P<0.001; clinical -11.8 ms/decade, P<0.001). There was no evidence of an increased effective reflecting distance by either method. TINF was shown to reliably represent RWTT only under highly unrealistic assumptions about input impedance. Conclusions-RWTT declines with age in parallel with increased PWV, with earlier effects of wave reflections and without a distal shift in reflecting sites. These findings have important implications for our understanding of the role of wave reflections with aging
