The (in)competent child: Subject positions of deviance in Norwegian day-care centres
Authors: Franck Karianne , Nilsen Randi Dyblie
Published: August 2015

In line with social studies of children and childhood, it is necessary to pay attention to local contextual understandings and practices in those places where constructions of children and childhood occur. The authors argue that the discourse of the competent child has become intertwined with a discourse of early intervention. In Norwegian day-care institutions, new practices of increased monitoring and evaluation of individual children have been observed. In this article, the authors explore day-care staff members’ descriptions of children who have not been formally diagnosed but who are positioned in between what is considered normal and deviating. While political documents stress the importance of early intervention and discovering special needs in the day-care setting, the authors suggest that this ‘discovery’ is context-bound, value-based and intertwined with ideas about children and childhood. From a study with day-care staff members, the following question is explored: ‘Which subject positions are present in day-care staff descriptions of children in between, and how do these positions legitimise the positioning of some children as deviating from perceived normality?’
Characterisation of an under-cured epoxy adhesive for use on the riv-bonded Bloodhound SSC lower chassis
Authors: Hannon Chris J , Evans Ben J
Published: August 2015

Bloodhound SSC is a vehicle that aims to raise the World Land Speed Record to over 1000 mile/h in Hakskeen Pan, South Africa. Its lower chassis is a riv-bonded fabrication made using steel sheet for skins and aluminium alloy machinings for bulkheads. Fasteners alone were enough to satisfy the lower chassis structural requirements; however, Redux 312/5 epoxy adhesive was used to increase the stiffness of the structure and limit potential corrosion due to water and soil ingress. The use of dissimilar metals in the chassis could lead to panel buckling during elevated cure temperatures, meaning a low adhesive cure temperature of 80–90 ℃ was required to minimise this risk. As the cure pressure for the lower chassis adhesive was achieved using only rivets, the variation of cure pressure was experimentally investigated and found to be within the manufacturer’s recommendations for large sections of the lower chassis. Tensile testing indicated the chassis could be cured at 80 ℃ instead of the optimum 121 ℃, without significant loss of mechanical strength. A thermal characterisation of the adhesive was conducted using dynamic mechanical analysis and differential scanning calorimetry. A variety of cure profiles was investigated and resulted in a cure profile that maximised the glass transition temperature ( Tg). An increase in cure duration to 8 h was recommended, which resulted in an increase in Tg by 15–24 ℃ to 83–92 ℃.
Growing up with foster siblings: Exploring the impacts of fostering on the children of foster parents
Authors: Serbinski Sarah
Published: August 2015

Growing up with foster siblings, the children of foster parents have experienced fostering from a different perspective which has continued to impact them throughout their lives. In this qualitative study, the experiences of 12 daughters of foster parents (aged 20–33 years) are explored, along with how they cope with their fostering experiences. Open-ended interviews, demographic questionnaires, object sharing, photographing the object, photo-feedback, and memo-writing were included within the data collection process. Data analysis included initial coding, focused coding, and memo-writing. Dedoose, a data management system, was used to assist in analysing the multiple data sources. Findings reveal that the daughters of foster parents are exposed to multiple foster sibling relationships due to the temporary nature of foster care. To protect their emotional well-being, these participants become apprehensive about developing relationships with new foster siblings, as well as with friends and romantic partners. Participating daughters sought emotional support from their mothers who established a strong, stable, and supportive relationship with them. Recommendations for foster parents and social workers are suggested.
Caring for a Person With Amnestic Mild Cognitive Impairment
Authors: Woolmore-Goodwin Sarah , Kloseck Marita , Zecevic Aleksandra , Fogarty Jennifer , Gutmanis Iris
Published: August 2015

While much of the literature on caregiver burden has focused on caregiving for people living with Alzheimer's disease (AD) there is little information on the experience of caring for a loved one living with amnestic Mild Cognitive Impairment (aMCI), the group most likely to convert to AD. A hermeneutic phenomenological approach was used to understand the organizing principles that give experiences of being form and meaning in the lifeworld. Study findings highlight the precarious nature of caregiver role acquisition and the heterogeneity that is present among informal care providers. Specifically, the findings suggest that the wearing of multiple situational masks is required by the carer to cope with accumulated progressive losses suffered as they continually adjust to their new and evolving carer identity. Support groups specific to the carers of those living with aMCI are needed in an effort to remove these masks and to validate this unique caregiving experience.

Published: August 2015

Pythiosis is a disease caused by Pythium insidiosum, a fungus-like organism. P. insidiosum is pathogenic in mammals, particularly in horses, dogs, and humans. Human pythiosis can be classified into 4 types: (1) cutaneous/subcutaneous, (2) ocular, (3) vascular, and (4) disseminated pythiosis. Vascular pythiosis is a rare disease but a serious limb- and life-threatening infection. We reviewed 22 cases over a 10-year period in Maharaj Nakorn Chiang Mai/Chiang Mai University Hospital. The survival rate was around 63.6% during our follow-up period. The only effective treatment was complete excision of the infected tissue, which was done mainly by major amputation, such as above-knee amputation. This report raises awareness of this disease, which needs preemptive diagnosis and appropriate treatment.
Sports Nutrition Advice for Adolescent Athletes
Authors: Bingham Mary Ellen , Borkan Mimi E. , Quatromoni Paula A.
Published: August 2015

Adolescents participating in sport have high demands for nutritional adequacy to meet their needs for growth, development, wellness and athletics. Nutritional risk can be quite high in this population due to their unique needs, low access to credible information and nutrition professionals, and misinformation in the media and marketplace specifically targeting athletes. Physicians and other health professionals have an opportunity to communicate nutrition facts and make evidence-based recommendations about healthy eating in the setting of their ongoing interactions with adolescent athletes and their families. The purpose of this review is to describe the nutritional needs of adolescents participating in sport and highlight the potential for nutritional risk. Endorsed by professional organizations, our recommendations emphasize a balanced eating pattern that includes a wide variety of fresh, minimally processed whole foods. Our approach is to empower and teach adolescents to take responsibility for planning, preparing, and providing themselves consistent access to foods and fluids that deliver nutrients needed for proper fueling and recovery. Specific talking points that health professionals can use in brief interactions with patients and families are provided to endorse key behavioral strategies that young athletes can adopt to achieve peak athletic performance and optimal nutritional status.
Computational fluid dynamics simulations and tests for improving industrial-grade gas mask canisters
Authors: Su Yin-Chia , Li Chun-Chi
Published: August 2015

This study proposes an efficient, cost-effective analytical methodology involving computational fluid dynamics for improving the performance of industrial-grade gas mask canisters. Computational fluid dynamics and the quadratic Forchheimer equation, used for calculating high momentum loss, were applied for analyzing the flow fields of six gas mask canisters. Streakline flow visualization and compression tests were conducted to determine the design performance. The results indicated that the designed honeycomb passageway in the canister demonstrated superior aerodynamics and structural loading to the original design. The honeycomb passageway design enhanced the flow rectification and increased the passageway sizes, improving the effective flow-through area and reducing the inhalation resistance. Finally, an improved prototype was produced based on the honeycomb passageway design. Aerosol penetration and hydrogen cyanide breakthrough tests confirmed that the improved prototype achieved a P100-level filter efficiency performance and maintained a 60-min breakthrough time. Without replacing the raw material, the inhalation resistance and absorbency of the improved prototype reduced by 46.48% and 33%, respectively, compared with the original canister.
Adverse events experienced by participants in a back pain walking intervention: A descriptive study
Authors: Krein Sarah L , Abdul-Wahab Yousef , Kadri Reema , Richardson Caroline R
Published: August 2015

Objective

To understand the range and potential severity of adverse events reported by patients with back pain who were participating in a walking intervention.

Methods

Data were obtained from participants in a randomized trial of a pedometer-based Internet-mediated intervention to promote walking and reduce back pain-related disability (n = 229 participants, 118 usual care, and 111 intervention). Participants reported adverse events throughout the 12-month study period. All reported events were reviewed and classified by system, severity, and study relatedness.

Results

A total of 600 adverse events were reported, 250 by those in usual care and nearly 350 by those in the intervention. After worsening back pain (27%), musculoskeletal events were the most commonly reported events (19%), followed by cardiovascular events (14%), infection (11%), and medical procedures (9%). There were three times as many musculoskeletal events in the intervention compared to the usual care group. Cardiovascular events, which were generally not serious and not walking related, were far less common than musculoskeletal injuries.

Conclusions

Individuals with chronic back pain can safely engage in a pedometer-based, unsupervised walking program. However, patients may benefit from focused counseling about musculoskeletal risks with specific attention to injury prevention measures such as gradually incrementing activity levels.

Published: August 2015

Objectives:

New targets and approaches are under investigation for the treatment of nonmuscle invasive bladder cancer (NMIBC). Preclinical data suggest cyclooxygenase-2 (COX-2) as a promising target. Celecoxib, a COX-2 selective inhibitor, inhibits tumor development and enhances survival, both in vitro and in vivo models of bladder cancer. Therefore, we conducted a pilot study of celecoxib to prevent recurrence in patients with intermediate risk NMIBC.

Methods:

Treatment with celecoxib was administered orally for 12 months and compared with a contemporary series of patients treated with intravesical mitomycin C (MMC), given weekly for 4 weeks and then monthly for 11 months. Primary endpoints were time to first recurrence and adverse events.

Results:

From 2003 through 2006, 58 patients were treated with celecoxib and compared with 66 patients receiving MMC. After a median follow up of 75 months, 49 patients were disease free, including 23 (34.85%) in the MMC group and 26 (44.8%) in the celecoxib group. Median disease-free interval was 67 months [95% confidence interval (CI) 35.8 to NA] versus 41 months (95% CI 27.1–67.1; log-rank p = 0.25) for patients treated with MMC and celecoxib, respectively. In the multivariate analysis, treatment was not found to be an independent predictor for recurrence [hazard ratio (HR) 0.76, 95% CI 0.47–1.22, p = 0.25). Overall, 45 AEs were recorded in 35/124 patients. There were no differences between the two groups.

Conclusions:

Our data support a clinical benefit of celecoxib and encourage future trials in which COX-2 inhibitors may be tested in selected patients with NMIBC.
Women Doing Leadership
Authors: Walker Robyn C. , Aritz Jolanta
Published: August 2015

Although women in the United States make up about half of the workforce, only 14.6% of executive officer positions in the Fortune 500 and 16.9% of Fortune 500 board of director seats in 2013 were held by women, numbers that have remained flat for the past decade. Decades after the so-called “feminist revolution,” women are still struggling to be seen as leaders within organizations even though many have put in place hiring and recruitment policies to help eliminate this problem. Our study examines this disparity by observing how leadership emerges and is negotiated in discourse among male and female participants in decision-making groups in a masculine organizational culture. First, it identifies whether female participants randomly assigned to mixed-gender groups emerge as leaders. Second, it analyzes the discourse of those competing for leadership positions in mixed groups to identify the effects of leadership style on leader attribution by others. Of the 22 mixed-gender groups ( N = 110) that took part in our study, no woman emerged as the unanimously chosen leader, even though women were identified as leaders by transcript coders. This article uses a case study approach to analyze leadership emergence in two mixed groups in which women were recognized by some members as demonstrating leadership. It then looks at a third case that demonstrates how some discourse behaviors that have been recognized as leadership may not be viewed as such in a masculine organizational culture. Study results illustrate how organizational culture can define accepted ways of “doing” leadership and affect who is and who is not recognized as a leader, particularly in terms of gender.
Activity Monitors Step Count Accuracy in Community-Dwelling Older Adults
Authors: Johnson Marquell
Published: August 2015

Objective: To examine the step count accuracy of activity monitors in community-dwelling older adults. Method: Twenty-nine participants aged 67.70 ± 6.07 participated. Three pedometers and the Actical accelerometer step count functions were compared with actual steps taken during a 200-m walk around an indoor track and during treadmill walking at three different speeds. Results: There was no statistical difference between activity monitors step counts and actual steps during self-selected pace walking. During treadmill walking at 0.67 m∙s−1, all activity monitors step counts were significantly different from actual steps. During treadmill walking at 0.894m∙s−1, the Omron HJ-112 pedometer step counts were not significantly different from actual steps. During treadmill walking at 1.12 m∙s−1, the Yamax SW-200 pedometer steps were significantly different from actual steps. Discussion: Activity monitor selection should be deliberate when examining the walking behaviors of community-dwelling older adults, especially for those who walk at a slower pace.
Enhancing 2D Cervical Length With 3D Cervix Imaging Emphasizing the Center Reference Point
Authors: England Joey , Hall Rebecca , Andrews Nicholas L. , Nirgudkar Pranita , Izquierdo Luis
Published: August 2015

Use of transvaginal ultrasonography for cervical length measurement at the 20-week anatomic examination has been suggested as a screening method to predict the risk of preterm birth. This article describes a three-dimensional ultrasonographic multiplanar imaging method of cervical length measurement by manipulating the center reference point and volume axes. This methodology should yield a more consistent, accurate measurement of the cervical length compared to conventional two-dimensional ultrasonographic methods. Also described are additional software image manipulation techniques to enhance visualization of the relational anatomy of the cervix. Precise utilization of the center reference point and available image reconstruction software augment current two-dimensional morphologic information of the lower genital tract.
Assessing the Extent to Which Current Clinical Research is Consistent with Patient Priorities: A Scoping Review Using a Case Study in Patients on or Nearing Dialysis

Published: August 2015

Purpose of review:

There is growing acknowledgement that engaging patients to identify their research priorities is important. Using a case study of patients on or nearing dialysis, we sought to assess the extent to which recently completed and ongoing clinical research was consistent with priorities identified by patients, caregivers, and clinicians.

Sources of information:

Over a 4-year sampling frame (January 2010 to December 2013), we systematically searched the medical literature (top 5 nephrology and top 10 general medicine journals accessed through MEDLINE via Ovid), international randomized controlled trial (RCT) registries, and national government and kidney research funding organizations (Canada, U.S., Australia, and U.K.) for published clinical studies, registered RCTs, and funded clinical studies, respectively. Published clinical studies, registered RCTs, and funded clinical studies were categorized as to whether or not they were consistent with the top 10 research priorities identified by patients, their caregivers, and clinicians in a recent comprehensive research priority setting exercise.

Findings:

The search yielded 4293 published articles, 688 RCTs, and 70 funded studies, of which 1116 articles, 315 RCTs, and 70 funded studies were eligible for inclusion. Overall 194 published studies (17.4 %), 71 RCTs (22.5 %), and 15 funded studies (21.4 %) included topics consistent with the top 10 research priorities identified by patients. Four of the top 10 research priorities, including strategies to improve the management of itching, increase access to kidney transplantation, assess the psychosocial impact of kidney failure, and determine the effects of dietary restriction received virtually no attention.

Limitations:

The top 10 priorities we used to categorize included studies were identified by Canadian patients, caregivers, and clinicians. The top research priorities may vary across different countries. The proportion of published studies that are consistent with the top 10 priorities could be different in nephrology journals with lower impact factors. Studies related to kidney transplantation and the psychosocial impact of kidney failure may have been published in journals not included in our search strategy.

Implications:

The majority of recently completed or ongoing clinical studies in patients on or nearing dialysis do not address the top research priorities of patients, raising concerns that current clinical research may not be meeting the needs of the ultimate consumer, in this case, patients on or nearing dialysis. Greater involvement of patients in research is required to bridge the gap between research and patients' needs.
Thyroid Hormone at Near Physiologic Concentrations Acutely Increases Oxygen Consumption and Extracellular Acidification in LH86 Hepatoma Cells
Authors: McAninch Elizabeth A. , Miller Bradford T. , Ueta Cintia B. , Jo Sungro , Kim Brian W.
Published: August 2015

Thyroid hormone (T3) has been known to regulate the basal metabolic rate for more than a century, but mechanistic understanding is lacking both at the level of the intact organism and in terms of how T3 alters energy expenditure in individual tissues. The current studies investigate the question of which metabolically relevant genes respond acutely as T3 concentrations increase through the physiologic range in liver cells. Because this has been technically unfeasible historically, we developed a modified protocol for extracellular flux analysis using a 96-well Extracellular Flux Analyzer (Seahorse Bioscience). Using a modified extracellular flux protocol and LH86 human hepatoma cells, we established an experimental system where small but significant changes in O2 consumption could be reproducibly quantified as hypothyroid cells were exposed to near-physiologic final concentrations of T3 approximately 2 orders of magnitude lower than most studies (0.04nM free T3), in only 6–7 hours. Taking advantage of the nondestructive nature of 96-well Extracellular Flux Analyzer measurements, the acute, direct, transcriptional changes that occur were measured in the exact same cells demonstrating increased O2 consumption. An unbiased, genome-wide microarray analysis identified potential candidate genes related to fatty acid oxidation, angiogenesis, nucleotide metabolism, immune signaling, mitochondrial respiration, and cell proliferation. The identified transcriptome is likely enriched in the genes most important for mediating the energetic effects of T3 in hepatoma cells.
Pentraxin-3 Is a TSH-Inducible Protein in Human Fibrocytes and Orbital Fibroblasts
Authors: Wang Hao , Atkins Stephen J. , Fernando Roshini , Wei Rui-Li , Smith Terry J.
Published: August 2015

CD34+ fibrocytes are bone marrow–derived monocyte progenitor cells that traffic to sites of tissue injury and repair. They putatively infiltrate the orbit in thyroid-associated ophthalmopathy where they appear to transition into CD34+ orbital fibroblasts (OFs) that interact with residential CD34− fibroblasts. A unique phenotypic attribute of fibrocytes and CD34+ OFs is their expression of the functional thyrotropin receptor (TSHR) and other “thyroid-specific” proteins. When activated through TSHR, fibrocytes express a number of cytokines and other inflammatory genes. Here we sought to determine whether pentraxin-3 (PTX-3), an acute-phase protein involved in inflammation and autoimmunity, might be induced by TSH in fibrocytes and OFs. These cells were collected from patients with Graves disease and healthy individuals. PTX-3 mRNA levels were determined by real-time PCR, protein was determined by ELISA and Western blot, and PTX-3 gene promoter activity was assessed with reporter assays. PTX-3 expression was induced by TSH in both cell types, regardless of the health status of the donor and was a consequence of increased steady-state PTX-3 mRNA levels. M22, a TSHR-activating monoclonal antibody, also induced PTX-3. The induction could be attenuated by dexamethasone and by IGF-I receptor–blocking antibodies, teprotumumab and 1H7. TSH effects were mediated through phosphatidylinositol 3-kinase/AKT, mammalian target of rapamycin/p70s6k, Janus tyrosine kinase 2 pathways, and enhanced PTX-3 mRNA stability. These findings indicate that PTX-3 is a TSH target gene, the expression of which can be induced in fibrocytes and OFs. They suggest that PTX-3 might represent a previously unidentified nexus between the thyroid axis and the mechanisms involved in tissue remodeling.
The Factory of Individuation: Cultural Labor and Class Composition in the Metropolis
Authors: Shukaitis Stevphen , Figiel Joanna
Published: August 2015

This article addresses the class composition of artistic and cultural labor in the metropolis: practices bringing with them political possibilities and potentials for renewed economic growth, but also the threat of exploitation and precarity. To shed light on the area of knowledge engaging with the lived realities of creative workers and the forms of subjectivation occurring in forms of labor, we bring together existing accounts addressing the politics of cultural work and the findings of our “Metropolitan Factory” research project. The research project, based on an investigation of the conditions and activities of independent cultural producers and drawing from the tradition of workers' inquiry, addresses, among other issues, the spatial organization of the creative labor process, the language used by workers to describe relations between life and work, and various forms of self-expression.
The Entrepreneurial Subject and the Objectivization of the Self in Social Media
Authors: Flisfeder Matthew
Published: August 2015

This article challenges the Foucauldian conception of the neoliberal subject by addressing self-promotion as a key feature of users' engagement with social media websites. The essay argues that the rational choice rhetoric of neoliberal entrepreneurialism involves a process of further objectivizing and reifying—rather than producing—the subject by increasingly commodifying the time spent outside of paid labor. The neoliberal idea of investing in one's human capital is compared to the Marxian category of the reproduction of labor-power, which, in the neoliberal context, is subdivided into the time spent on the promotion of the Self. Social media help to facilitate the latter by providing a material space for self-promotion and result in the expansion of working time into what Jonathan Crary calls “24/7 temporalities.” The arguments made here are aided by developing a neo-Lacanian conception—in opposition to the Foucauldian one—of neoliberal subjectivity.
Different functional modes of BAR domain proteins in formation and plasticity of mammalian postsynapses
Authors: Kessels Michael M. , Qualmann Britta
Published: August 2015

A plethora of cell biological processes involve modulations of cellular membranes. By using extended lipid-binding interfaces, some proteins have the power to shape membranes by attaching to them. Among such membrane shapers, the superfamily of Bin–Amphiphysin–Rvs (BAR) domain proteins has recently taken center stage. Extensive structural work on BAR domains has revealed a common curved fold that can serve as an extended membrane-binding interface to modulate membrane topologies and has allowed the grouping of the BAR domain superfamily into subfamilies with structurally slightly distinct BAR domain subtypes (N-BAR, BAR, F-BAR and I-BAR). Most BAR superfamily members are expressed in the mammalian nervous system. Neurons are elaborately shaped and highly compartmentalized cells. Therefore, analyses of synapse formation and of postsynaptic reorganization processes (synaptic plasticity) – a basis for learning and memory formation – has unveiled important physiological functions of BAR domain superfamily members. These recent advances, furthermore, have revealed that the functions of BAR domain proteins include different aspects. These functions are influenced by the often complex domain organization of BAR domain proteins. In this Commentary, we review these recent insights and propose to classify BAR domain protein functions into (1) membrane shaping, (2) physical integration, (3) action through signaling components, and (4) suppression of other BAR domain functions.
The effect of discontinuous gas exchange on respiratory water loss in grasshoppers (Orthoptera: Acrididae) varies across an aridity gradient
Authors: Huang Shu-Ping , Talal Stav , Ayali Amir , Gefen Eran
Published: August 2015

The significance of discontinuous gas-exchange cycles (DGC) in reducing respiratory water loss (RWL) in insects is contentious. Results from single-species studies are equivocal in their support of the classic ‘hygric hypothesis’ for the evolution of DGC, whereas comparative analyses generally support a link between DGC and water balance. In this study, we investigated DGC prevalence and characteristics and RWL in three grasshopper species (Acrididae, subfamily Pamphaginae) across an aridity gradient in Israel. In order to determine whether DGC contributes to a reduction in RWL, we compared the DGC characteristics and RWL associated with CO2 release (transpiration ratio, i.e. the molar ratio of RWL to CO2 emission rates) among these species. Transpiration ratios of DGC and continuous breathers were also compared intraspecifically. Our data show that DGC characteristics, DGC prevalence and the transpiration ratios correlate well with habitat aridity. The xeric-adapted Tmethis pulchripennis exhibited a significantly shorter burst period and lower transpiration ratio compared with the other two mesic species, Ocneropsis bethlemita and Ocneropsis lividipes. However, DGC resulted in significant water savings compared with continuous exchange in T. pulchripennis only. These unique DGC characteristics for T. pulchripennis were correlated with its significantly higher mass-specific tracheal volume. Our data suggest that the origin of DGC may not be adaptive, but rather that evolved modulation of cycle characteristics confers a fitness advantage under stressful conditions. This modulation may result from morphological and/or physiological modifications.

Authors: Xie Juan , Li Meixia , Hao Yongjing , Meng Xiaocai , Meng Yuan , Li Zhen
Published: August 2015

Using only zinc nitrate, ferric nitrate and sodium hydroxide as reactants, rod-like and flower-like α-Fe2O3/ZnO composites were prepared via a simple and rapid solution route by controlling the composition of precursor solution. The products were characterized by X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM) and UV-vis diffuse reflectance spectra (UV-vis DRS). Photocatalytic activity of the as-prepared α-Fe2O3/ZnO composites was evaluated by degradation of methyl orange (MO) under simulated solar light. The results indicated that both α-Fe2O3/ZnO composites possess higher photocatalytic activity than commercial P25 TiO2. In addition, possible reasons why α-Fe2O3/ZnO composites have excellent photocatalytic performance were discussed.
Development of rock bitwear models for selected rocks in Nigeria using dominant rock properties
Authors: Babatunde Adebayo
Published: August 2015

This work deals with the development of wear rate models for some selected rocks in Nigeria. Rock samples obtained were tested for chemical composition, point load strength index, uniaxial compressive strength, and porosity in the laboratory. These properties were correlated with wear rate. The results of statistical correlation matrix revealed that silica content, point load strength index, uniaxial compressive strength, porosity, Equivalent Quartz Content (EQC), rebounds hardness value and circularity factor are dominant rock properties affecting bit wear having high coefficient of correlation. These rock properties were used for development of regression model to predict wear rate for each of the selected rocks. The regression equation for predicting bit wear rate of porphyritic hornblende-granite is WG = 0.135 – 0.001 Is50 – 0.002EQC – 0.007n, the regression model has multiple correlation coefficient of R2 = 0.992 (99.2%), which means that 99.2% of the variation in wear rate can be attributed to variation in point load strength Index (Is50), Equivalent Quartz Content (EQC) and porosity (n) of porphyritic hornblende-granite. The results of comparison between field measured wear rate and simulated wear rate followed the same trend and the coefficient of correlation between wear rate (dependent variable) and regression standard predicted value is R2 = 0.99, which suggest that the models are valid.
Lattice Boltzmann investigation of thermal effect on convective mixing at the edge of solvent chamber in CO2-VAPEX process
Authors: Atia Abdelmalek , Mohammedi Kamal
Published: August 2015

The high viscosity of heavy oil is a serious problem for the recovery efficiency of this resource by conventional methods. Since a few past years, the vapour extraction process (VAPEX) has emerged as a promising technology for the recovery of heavy oils and bitumen in reservoirs where thermal methods, such as steam-assisted gravity drainage cannot be applied. Recently, the use of CO2 as a solvent is believed to make the VAPEX process more economical and environmentally and technically attractive. Convective mixing at the edge of the solvent chamber enhances mass and heat transfer rates which increases oil mobility and production rate. The objective of this study is to analysis the influence of the main controlling parameters, such as buoyancy ratio and Prandtl number on the flow patterns and mass transfer mechanism, in order to understand the thermal effect on the dissolution of carbon dioxide through natural convection at the boundary layer of solvent chamber of CO2-VAPEX process. The numerical results obtained by lattice Boltzmann method show that the flow structure and the mass transfer mechanism are strongly depend on the buoyancy ratio and Prandtl number. So, the performances of CO2-VAPEX process are strongly influenced by thermal effect; and we found that it has negative consequences on this process.

Effects of global warming on wind energy potential
Authors: Gungor Afsin
Published: August 2015

A recent study conducted to determine the potential of wind power in Nigde which used 35 year wind data, has shown that global warming may also affect the potential of wind power negatively. The wind data were collected on 10 min time intervals at 10 m mast height. The missing data were 3.9%. When the results are closely examined it is observed that the potential of wind power has decreased dramatically throughout the years. The 35 yearly data has shown a decrease of wind power density from 48.14 W/m2 to 13.25 W/m2. These results are of extreme importance because of various reasons given below.

The first problem we may see is that it is possible to observe an area which was once regarded as a highly suitable region for wind energy generation is now not as sustainable as it was assumed to be. Thus it may stand as a hidden but great risk for certain wind farm investments. Therefore, the calculation of wind power potential is a really serious matter to deal with. Moreover, if the loss of the wind power potential is observed consistently and continually as a result of global warming, the only reasonable solution to this problem may be the relocation of the whole power-plant.
The Influence of Parent Sport Behaviours on Children's Development: Youth Coach and Administrator Perspectives
Authors: Ross Anthony J. , Mallett Clifford J. , Parkes Jarred F.
Published: August 2015

There has been much literature and anecdotal accounts reporting poor parental behaviours in the youth sporting context. Youth coaches and administrators, who regularly interact with parents within the youth sporting domain, are potentially a key source for investigating the influence of parents' sport-related behaviours on youths' sporting experiences. Nevertheless, the voice of coaches and administrators has been limited. In this study, the authors sought to develop an understanding of youth sport coaches' and administrators' perspectives of parent sport behaviours' influence on children's development across various sport settings. Additionally, the authors explored participant awareness of and their perspectives of efficacy in relation to current parent education programs in Australia. Semi-structured interviews were conducted with twelve youth sport coaches and administrators (eight coaches, four administrators; eight males, four females) with an average of nine years experience. Coaches and administrators reported considerably more frequent negative interactions with parents than positive interactions. Participants also reported more negative observations of parent-child communications than positive observations. Four participants reported exposure to parent education efforts but all perceived these approaches to be inadequate. Recommendations, practical implications, and future avenues of research are discussed.

This study investigated the use of a movement assessment protocol for under-14 rugby league players by evaluating the relationships between chronological age, maturation, and anthropometry, and fitness and qualitative movement assessments (QMA) of 84 rugby league players within a talent development environment. A one-way ANOVA showed Quartile 1 players were more mature, taller (173.0±7.4 vs 165.0±8.0 cm) and heavier (72.5 vs 58.7 kg) than Quartile 4 players, with no difference evident for fitness or QMA measures. Earlier maturing players had significantly greater upper body power (5.39±0.46 vs 4.42±0.68 m), 20m speed (3.48±0.14 vs 3.65±0.19s) and power pass QMA (13.88±2.18 vs 12.00±1.98) than later maturing players. Body mass was positively related to power pass fitness (r=0.50) and QMA (r=0.22) scores, with negative relationships found for vertical jump performance (r=−0.24), sprint QMA (r=−.29) and turn off either foot QMA (r=−0.26). There is a need to educate coaches about the use of both fitness testing and qualitative movement assessments to identify talented U14 rugby league players, which potentially reduces relative age and maturational biases.
The Intervention Tone of Coaches' Behaviour: Development of the Assessment of Coaching Tone (ACT) Observational Coding System
Authors: Erickson Karl , Côté Jean
Published: August 2015

The importance of coaches' interactive behaviour with respect to athlete development has long been recognized. While a number of observational coding systems exist to record the instructional content of coaches' interactive behaviour, none is designed to explicitly capture the intervention tone of these interactions – ‘how’ coaches say what they say. The current project entailed the development of a new behavioural coding system designed to focus on the intervention tone of youth sport coaches' interactive behaviour. Behaviour categories were developed through an iterative combination of literature review and observation of recorded youth sport coaching sessions. A coder training protocol was developed and refined until coders consistently met a minimum standard of agreement with respect to both inter- and intra-rater reliability. The full coding system was then initially validated across six different team and individual youth sports in multiple contexts over a one year period.
Drive Performance for Able-Bodied and Disabled Golfers

Golf is a popular leisure and competitive activity for individuals with disabilities. The current golf handicap system does not take into account the possible challenges of playing golf with any form of physical disability. The aim of this study was to examine golf driving performance measures, comparing golfers with various types of physical disabilities to able-bodied golfers. Through drive shot ball launch analysis, this study compared amputees (single leg, below and above knee), deaf, visually impaired, polio, Les Autres and arthrogryposis golfers to able-bodied golfers with similar golf handicaps. Twenty-seven able-bodied (handicap category 3, 12.4 ± 7.0) and 15 disabled (handicap category 3, 18.2 ± 9.2) hit 10 drives each. Able-bodied golfers presented longer but less accurate drives (208.1 m carry, 4.6 m lateral deviation), and concomitant higher club head and ball velocity than disabled golfers (157.6 m carry, 6.0 m lateral deviation) [p<0.001]. The apparent difference in outcome performance cannot be fully accounted for by the small difference in golf handicap score, thus disabled golfers appear to be penalised/disadvantaged by the current golf handicap classification rules.
Analysis of Initial Bubble Acceleration Using the Level-Set Method
Authors: Dominik M. , Cassel K. W.
Published: August 2015

A new axisymmetric level-set code for incompressible, multiphase flows using the vorticity-streamfunction formulation has been developed. The level-set method is well suited to treating multiphase flows having complex interface shapes that may undergo topological changes, such as merging and splitting of bubbles. The initial acceleration of a single air bub- ble in water has been analyzed and found to be approximately 3.3 g, not 2 g, which is the predicted value from an added mass analysis based on potential-flow theory.
On Capability of the Nonlinear k-ε Turbulence Model in the Prediction of Non-Isotropic Stratified Flows
Authors: Shamsnia H. , Hejazi K.
Published: August 2015

The commonly used linear k-ε turbulence model has been shown to be incapable of accurate prediction of turbulent flows where non-isotropy is present. Two types of non-isotropic flows which are due to stratification, and consequently variation of density through vertical layers, are saline water flow and the stratified flows due to temperature gradients which both have a wide range of applications in environmental fluid mechanics. In this study a nonlinear k-ε turbulence model firstly presented by Speziale [1] has been deployed and implemented in the hydrodynamic model WISE (Width Integrated Stratified Environments), a 2DV numerical model originally developed by Hejazi [2]. The energy equation has been also added and solved in the hydrodynamic model. The model solves the fully nonlinear Navier-Stokes equations based on an ALE (Arbitrary Lagrangian- Eulerian) description. The simulated results have been compared against the measured values reported in the literature and have shown acceptable agreements. The predictions are also compared with the results of the original model which has employed a standard buoyant k-ε turbulence model, showing the superiority of the non-linear k-ε developed herein compared to the linear k-ε turbulence model in the prediction of non-isotropic flows especially for the velocity profiles.

IQ and Mutual Fund Choice
Authors: Grinblatt Mark , Ikäheimo Seppo , Keloharju Matti , Knüpfer Samuli
Published: August 2015

We show that cognitive ability influences mutual fund choice: high-IQ investors avoid funds with high management fees. Two competing stories can explain this phenomenon. One is that high-IQ consumers benefit less from costly services, as they find it easier to make informed financial decisions without external help. The alternative story is that these investors are less likely to overpay for the services they receive because they are either better judges of value or more capable of discerning the price charged for these services. A comprehensive data set of Finnish males’ fund holdings supports both stories: consistent with the first story, high-IQ investors tend to avoid funds sold via expensive service-intensive channels and prefer a mix of equity and bond funds to expensive readily packaged balanced funds. Consistent with the alternative story, IQ and fees are inversely correlated, even after controlling for many fund services, including any operating at the fund family level.
