Intestinal Adaptation Following Resection
Authors: Tappenden Kelly A.
Published: March 2014

Intestinal adaptation is a natural compensatory process that occurs following extensive intestinal resection, whereby structural and functional changes in the intestine improve nutrient and fluid absorption in the remnant bowel. In animal studies, postresection structural adaptations include bowel lengthening and thickening and increases in villus height and crypt depth. Functional changes include increased nutrient transporter expression, accelerated crypt cell differentiation, and slowed transit time. In adult humans, data regarding adaptive changes are sparse, and the mechanisms underlying intestinal adaptation remain to be fully elucidated. Several factors influence the degree of intestinal adaptation that occurs post resection, including site and extent of resection, luminal stimulation with enteral nutrients, and intestinotrophic factors. Two intestinotrophic growth factors, the glucagon‐like peptide 2 analog teduglutide and recombinant growth hormone (somatropin), are now approved for clinical use in patients with short bowel syndrome (SBS). Both agents enhance fluid absorption and decrease requirements for parenteral nutrition (PN) and/or intravenous fluid. Intestinal adaptation has been thought to be limited to the first 1–2 years following resection in humans. However, recent data suggest that a significant proportion of adult patients with SBS can achieve enteral autonomy, even after many years of PN dependence, particularly with trophic stimulation.

Published: March 2014

Empirical research on workaholism has been hampered by a lack of consensus regarding the definition and appropriate measurement of the construct. In the present study, we first review prior conceptualizations of workaholism in an effort to identify a definition of workaholism. Then, we conduct a meta-analysis of the correlates and outcomes of workaholism to clarify its nomological network. Results indicate that workaholism is related to achievement-oriented personality traits (i.e., perfectionism, Type A personality), but is generally unrelated to many other dispositional (e.g., conscientiousness, self-esteem, positive affect) and demographic (e.g., gender, parental status, marital status) variables. Findings are mixed regarding the relationship between workaholism and affectively laden variables, which speaks to the complex nature of workaholism. Results also show that workaholism is related to many negative outcomes, such as burnout, job stress, work–life conflict, and decreased physical and mental health. Overall, results provide solid evidence that workaholism is best conceptualized as an addiction to work that leads to many negative individual, interpersonal, and organizational outcomes.

Published: March 2014

This study aimed to translate into Chinese the Diabetes Care Profile (DCP), a measure of psychosocial factors and diabetes treatment, and to test the reliability and validity of the instrument within a Chinese population. The English version of the DCP was translated into Chinese following the standard translation methodology with consideration to cultural adaptation. The questionnaire was administered to 313 people with type 2 diabetes in an urban community in Beijing, China. Cronbach’s α coefficient was used to calculate reliabilities, which ranged from .55 to .86 on DCP subscales. Mean values on the DCP differed by diabetes treatment as expected and supports the construct validity of the DCP. The overall score on the DCP correlated well both with blood glucose levels and with a validated measure of a Chinese version of the Diabetes Specific Quality of Life scale, thus supporting the DCP’s criterion validity. The DCP is an acceptable measure of the psychosocial factors related to diabetes and its treatment in a Chinese population with type 2 diabetes.
Regression Discontinuity Design in Criminal Justice Evaluation
Authors: Rhodes William , Jalbert Sarah Kuck
Published: March 2014

Background:

Corrections agencies frequently place offenders into risk categories, within which offenders receive different levels of supervision and programming. This supervision strategy is seldom evaluated but often can be through routine use of a regression discontinuity design (RDD). This article argues that RDD provides a rigorous and cost-effective method for correctional agencies to evaluate and improve supervision strategies and advocates for using RDD routinely in corrections administration. The objective is to better employ correctional resources.

Method:

This article uses a Neyman–Pearson counterfactual framework to introduce readers to RDD, to provide intuition for why RDD should be used broadly, and to motivate a deeper reading into the methodology. The article also illustrates an application of RDD to evaluate an intensive supervision program for probationers.

Result:

Application of the RDD, which requires basic knowledge of regressions and some special diagnostic tools, is within the competencies of many criminal justice evaluators. RDD is shown to be an effective strategy to identify the treatment effect in a community corrections agency using supervision that meets the necessary conditions for RDD.

Conclusion:

The article concludes with a critical review of how RDD compares to experimental methods to answer policy questions. The article recommends using RDD to evaluate whether differing levels of control and correction reduce criminal recidivism. It also advocates for routine use of RDD as an administrative tool to determine cut points used to assign offenders into different risk categories based on the offenders’ risk scores.
The effectiveness of semantic therapy for the word finding difficulties of children with severe and complex speech, language and communication needs

Published: March 2014

Word finding difficulties are often seen in children with language difficulties. Their problem is readily observed and has led to investigations of its nature and encouraged attempts at intervention. Semantic errors in their naming suggest that their knowledge of items is poorly developed and that therapies to strengthen it may be effective. Twelve children between 7 and 11 years of age were offered 3 hours of semantic therapy in two 15-minute sessions per week for 6 weeks. The children had severe and complex speech, language and communication needs and all were in the bottom 5% for their age on a test of word finding. Two categories of items were treated. Each category was divided into sets of items that were directly treated, and items which appeared during therapy but were not specifically targeted. Categories and sets of items were counterbalanced across children. The children were blind assessed on naming the items before and after therapy and at a maintenance assessment 6 weeks after the treatment ceased. The children improved significantly on the treated items and on untreated items from the same category but not on items from the untreated category. Improvement was maintained at the maintenance assessment. Although results were significant, only medium effect sizes were obtained. These results add to the evidence that semantic therapy can help children with word finding difficulties. In assessing their clinical significance, the severity of the children’s communication problems should be taken into account.
Do mergers and acquisitions among small and medium-sized enterprises affect the performance of acquiring firms?
Authors: Arvanitis Spyros , Stucki Tobias
Published: March 2014

This article investigates the post-merger performance effects resulting from mergers and acquisitions (M&As), drawing on a representative sample taken from all Swiss M&As occurring between 2006 and 2008, the majority of which took place between small and medium-sized firms (SMEs). Using this data, the study was able to investigate the impact of M&As on differing measures of economic performance, and also on innovation for the post-merger period of 2008–2010. The study found positive statistically significant performance effects arising from M&As for three of five critical performance indicators utilized. Furthermore, the evidence suggests that growth is a principal motive for external mergers, while efficiency is more influential on internal mergers.
How Competitive Is “Competitive” Procurement in the Social Services?
Authors: Lamothe Scott
Published: March 2014

The scholarship on contracting generally argues that markets for social services are weak and lacking in competition. Using data gathered from Florida’s largest social service agency, the Department of Children and Families, this article adds to the discussion by constructing a more rigorous measure of competition that accounts for the quality of bidding entities. The findings indicate that while the measures used in earlier studies align reasonably well with the raw number of initial responders to competitive solicitations, they tend to overestimate competition when the quality component is included in the analysis. That is, social service markets may be even weaker than previously reported. Furthermore, an examination of the relationship between competition and performance fails to find a significant association.

Published: March 2014

Background

18F fluoro-deoxyglucose (FDG) positron emission tomography / computed tomography (PET/CT) is a well-recognized diagnostic tool used for staging and monitoring of therapy response for lymphomas. During the past decade diffusion-weighted (DW) magnetic resonance imaging (MRI) is increasingly being included in the assessment of tumor response for various cancers.

Purpose

To compare the change in maximum standardized uptake value (ΔSUVmax) from FDG PET/CT with the change in apparent diffusion coefficient (ΔADC) from DW MRI after initiation of the first cycle of chemotherapy in patients with Hodgkin's lymphoma (HL) and in patients with diffuse large B-cell lymphoma (DLBCL).

Material and Methods

Twenty-seven consecutive patients with histologically proven lymphoma and lymphomatous lymph nodes (LLN) of the neck (19 with HL, 8 with DLBCL) underwent FDG PET/CT and MRI of the neck before and after initiation of the first cycle of chemotherapy. The mean time interval from initiation of chemotherapy to imaging was 19 days and 2 days for FDG PET/CT and MRI, respectively. For each patient ΔSUVmax, ΔADC, and change in volume of the same LLN were compared.

Results

There was a significant mean decrease of SUVmax by 70%, but no significant change in ADC. There was no significant reduction in LLN volume.

Conclusion

There was no significant correlation between ΔSUVmax and ΔADC. Thus, our data do not support that FDG PET/CT can be replaced by early DW MRI for response evaluation in lymphoma patients.
Sexualizing the Self
Authors: Smolak Linda , Murnen Sarah K. , Myers Taryn A.
Published: March 2014

Self-sexualization refers to intentionally engaging in activities expressly to appear more sexually appealing. The purpose of our studies was to examine gender similarities and differences in how women and men conceptualize self-sexualization as well as introduce measures appropriate for large-scale data collection. In a qualitative study, we first established the existence of self-sexualization among women, although we were unable to document a similar construct among men. The Self-Sexualization Behavior Questionnaire for Women (SSBQ–W), developed over the course of three studies using samples from two small liberal arts colleges, demonstrated adequate internal consistency, stability, and construct validity. Discriminant validity for the SSBQ–W was demonstrated with the Surveillance subscale of the Objectified Body Consciousness Scale, the Sexualizing Behavior Scale, and the Enjoyment of Sexualization Scale. The SSBQ–W may especially be useful in addressing debates about the relationship of self-sexualization to sexual empowerment, agency, and oppression in young women. Additionally, our attempts to develop a parallel sound measure for men failed, and gender differences in item-by-item comparisons concluded that men are less likely to engage in specific self-sexualizing behaviors than women. These findings raise the possibility that self-sexualization is neither as meaningful nor as pervasive for men. In sum, our findings help to further refine how researchers and practitioners might best conceptualize self-sexualization, concluding that it is highly gendered activity that is largely confined to women and offering a measure for women that may promote further research.
A Cam Deformity Is Gradually Acquired During Skeletal Maturation in Adolescent and Young Male Soccer Players
Authors: Agricola Rintje , Heijboer Marinus P. , Ginai Abida Z. , Roels Pauline , Zadpoor Amir A. , Verhaar Jan A.N. , Weinans Harrie , Waarsing Jan H.
Published: March 2014

Background:

A cam deformity is a major risk factor for hip osteoarthritis, and its formation is thought to be influenced by high-impact sporting activities during growth.

Purpose:

To (1) prospectively study whether a cam deformity can evolve over time in adolescents and whether its formation only occurs during skeletal maturation and (2) examine whether clinical or radiographic features can predict the formation of a cam deformity.

Study Design:

Cohort study (prognosis); Level of evidence, 2.

Methods:

Preprofessional soccer players (N = 63; mean age, 14.43 years; range, 12-19 years) participated both at baseline and follow-up (mean follow-up, 2.4 ± 0.06 years). At both time points, standardized anteroposterior and frog-leg lateral radiographs were obtained. For each hip, the α angle was measured, and the anterosuperior head-neck junction was classified by a 3-point visual system as normal, flattened, or having a prominence. Differences between baseline and follow-up values for the α angle and the prevalence of each visual hip classification were calculated. Additionally, the amount of internal hip rotation, growth plate extension into the neck, and neck shaft angle were determined.

Results:

Overall, there was a significant increase in the prevalence of a cam deformity during follow-up. In boys aged 12 and 13 years at baseline, the prevalence of a flattened head-neck junction increased significantly during follow-up (13.6% to 50.0%; P = .002). In all hips with an open growth plate at baseline, the prevalence of a prominence increased from 2.1% to 17.7% ( P = .002). After closure of the proximal femoral growth plate, there was no significant increase in the prevalence or increase in severity of a cam deformity. The α angle increased significantly from 59.4° at baseline to 61.3° at follow-up ( P = .018). The amount of growth plate extension was significantly associated with the α angle and hip classification ( P = .001). A small neck shaft angle and limited internal rotation were associated with cam deformities and could also significantly predict the formation of cam deformities (α angle >60°) at follow-up.

Conclusion:

In youth soccer players, cam deformities gradually develop during skeletal maturation and are probably stable from the time of growth plate closure. The formation of a cam deformity might be prevented by adjusting athletic activities during a small period of skeletal growth, which will have a major effect on the prevalence of hip osteoarthritis.
Exploring the Validity and Robustness of a Competency Self-Report Instrument for Vocational and Higher Competence-Based Education

Published: March 2014

Research on the effectiveness of competence-based education (CB-education) across educational contexts and levels requires a new evaluation measurement. This study explores the face validity, construct validity, and robustness of a competency self-report instrument that is aligned with contemporary competence theory and with current educational practice based on CB-qualification frameworks. A pilot study showed face validity of the competency constructs and indicators according to students from various levels in tertiary education. The results of the principal components analyses and parallel analyses, using data from 351 secondary vocational education and academic students, show more construct validity and robustness for competency constructs that are concrete and easy to relate to specific situations (e.g., “applying expertise”) compared with the abstract competencies (e.g., “deciding and initiating”). This article sets out implications for designing and administrating uniform competency self-reports across educational levels and discusses suggestions for subsequent research.
Threat and imposition of economic sanctions 1945–2005: Updating the TIES dataset
Authors: Morgan T. Clifton , Bapat Navin , Kobayashi Yoshiharu
Published: March 2014

Recent research on economic sanctions has produced significant advances in our theoretical and empirical understanding of the causes and effects of these phenomena. Our theoretical understanding, which has been guided by empirical findings, has reached the point where existing datasets are no longer adequate to test important hypotheses. This article presents a recently updated version of the Threat and Imposition of Economic Sanctions dataset. This version of the data extends the temporal domain, corrects errors, updates cases that were ongoing as of the last release, and includes a few additional variables. We describe the dataset, paying special attention to the key differences in the new version, and we present descriptive statistics for some of the key variables, highlighting differences across versions. Since the major change in the dataset was to more than double the time period covered, we also present some simple statistics showing trends in sanctions use over time.
A Critical Practice Analysis of Response to Intervention Appropriation in an Urban School
Authors: King Thorius Kathleen A. , Maxcy Brendan D. , Macey Erin , Cox Adrienne
Published: March 2014

This qualitative case study focuses on factors mediating an urban school’s enactment of Response to Intervention (RTI). Over one school year, we (a) observed weekly RTI meetings, (b) debriefed observations weekly, (c) interviewed RTI team members, and (d) examined procedural documents. Analyses included post-observation debriefing and coding fieldnotes and interview transcripts; categorical meaning and themes were coded recursively. Informed by critical policy studies research and theory, findings indicated limited supports and minimal technical understandings of RTI. Educators appeared to replicate pre-RTI special education eligibility determination processes, manifested in scripts about student diagnoses based on minimal “interventions” and deficit-laden representations of students/families. Findings highlight challenges with urban schools’ RTI enactment and justify future critical qualitative research regarding learning in schools shifting practice under policy directives. Although the study focuses on RTI as a case-in-point, findings have implications for future research that utilizes critical practice approaches to analyze ways local contexts mediate policy enactment.
Rural Canadian Youth Exposed to Physical Violence
Authors: Laye Adele M. , Mykota David B.
Published: March 2014

Exposure to physical violence is an unfortunate reality for many Canadian youth as it is associated with numerous negative psychosocial effects. The study aims to assist in understanding resilience in rural Canadian youth exposed to physical violence. This is accomplished by identifying the importance of protective factors, as measured by the Resiliency Scale for Children and Adolescents (RSCA), and physical violence exposure, when used together, in predicting disruptive behavior, depression, and posttraumatic stress. Results indicate positive emotional reactivity is more important in protecting youth from developing psychological symptoms than sense of mastery and sense of relatedness. Differences between the effect of hearing reports, witnessing, and being victim to violence as well as differences between male and female youth were found. The study adds to the research on physical violence exposure, protective factors, and internalizing/externalizing problems in rural youth, with implications for implementing school-based programs.
Normalizing Sexual Violence
Authors: Hlavka Heather R.
Published: March 2014

Despite high rates of gendered violence among youth, very few young women report these incidents to authority figures. This study moves the discussion from the question of why young women do not report them toward how violence is produced, maintained, and normalized among youth. The girls in this study often did not name what law, researchers, and educators commonly identify as sexual harassment and abuse. How then, do girls name and make sense of victimization? Exploring violence via the lens of compulsory heterosexuality highlights the relational dynamics at play in this naming process. Forensic interviews with youth revealed patterns of heteronormative scripts appropriated to make sense of everyday harassment, violence, coercion, and consent. Findings inform discussions about the links between dominant discourses and sexual subjectivities as we try to better understand why many regard violence a normal part of life.
Polymorphism in Cytochrome P450 2D6, Glutathione S-Transferases Pi 1 Genes, and Organochlorine Pesticides in Alzheimer Disease
Authors: Singh Neeraj Kumar , Banerjee B. D. , Bala Kiran , Basu Mitra , Chhillar Neelam
Published: March 2014

Objectives:

It has been assumed that the association between Alzheimer disease (AD) and pesticides may be stronger among genetically susceptible individuals. The aim of the study was to examine the genetic polymorphism in cytochrome P450 2D6 ( CYP2D6) and glutathione S-transferases pi 1 ( GSTP1) with respect to organochlorine pesticides (OCPs) and metals in AD.

Methods:

This study included 100 patients with AD and 100 age-matched controls. The genetic polymorphisms were analyzed by restriction fragment length polymorphism. The OCPs and serum metal levels were determined using gas chromatography and an autoanalyzer, respectively.

Results:

We found a statistically significant association between AD and high levels of β-hexachlorocyclohexane (β-HCH; odds ratio [OR] = 2.064, 95% confidence intervals [95% CIs] = 1.373-3.102, dieldrin [OR = 2.086, 95% CI = 1.224-3.555], and copper [OR = 1.038, 95% CI = 1.012-1.064). The significant low level of magnesium (OR = 0.151, 95% CI = 0.047-0.489) even appears to have a protective role against AD. The GSTP1*B ( P = .009) and GSTP1*C ( P = .011) allelic variants were associated with increase in AD risk.

Conclusion:

This study demonstrates that the GSTP1*B and *C allelic variants may be considered a candidate gene for AD. It can be suggested that although CYP2D6*4 polymorphism is not a risk of AD, the CYP2D6*4 and GSTP1 polymorphism may interact with β-HCH, dieldrin, and copper to influence the risk of AD.
Social Gradient in Allostatic Load Among Danish Men and Women in Late Midlife

Published: March 2014

Objective: The objective of the present study is to describe the prevalence of allostatic load (AL) among Danish men and women in late midlife, and if there is a social gradient in AL. Method: A total of 5,420 participants from the Copenhagen Aging and Midlife Biobank (CAMB) aged 48 to 63 years (68.5% men, 31.5% women) underwent a health examination including standardized measures of height, weight, body fat, and blood pressure in 2009-2011. AL (range 0-14) was established by summing the scores of the poorest quartile for each of 14 biological variables related to the metabolic and immune systems. Results: We found a social gradient in AL in late midlife among men and women living in Denmark. Discussion: AL may be a potential biomarker for early aging in countries with a strong social welfare system. It is important for intervention studies to be aware of this type of biological vulnerability already present in late midlife.

Authors: Hansen Åse Marie , Andersen Lars L. , Skotte Jørgen , Christensen Ulla , Mortensen Ole Steen , Molbo Drude , Lund Rikke , Nilsson Charlotte Juul , Avlund Kirsten
Published: March 2014

Objective: The objective of the present study is to analyze gender differences and social class gradients in physical functions; and to study whether the social class gradients in physical functions in midlife differed between men and women. Method: This study used traditionally used physical performance tests and we added several tests of vigorous physical functioning (trunk muscle strength and power and sagittal flexibility). We measured reaction time, one-legged balance, sagittal flexibility, jump height, chair rise ability, trunk muscle- and handgrip strength in 5,412 participants aged 50 to 60 years (68.5% men). Results: We found gender differences and social class gradients for all physical performance tests. We did not find an interaction between social class and gender, indicating that the social gradient in physical functions did not differ between men and women. Discussion: Including measures of vigorous physical functioning may add to the existing knowledge on development of functional limitation and poorer functional health later in life.

Published: March 2014

Objective: The aim of the article is to analyze associations between sex, age, education, and social class and cognitive ability in late midlife and to evaluate differences in cognitive ability among the three Copenhagen Aging and Midlife Biobank (CAMB) cohorts. Method: The sample comprised 5,417 CAMB participants from three cohorts with scores on the Intelligenz-Struktur-Test 2000 R (I-S-T 2000 R). Results: Independent associations of cognitive ability with age, sex, education, and occupational social class were observed. Particularly, strong associations with cognitive ability were obtained for school education, and consistent sex differences were observed with higher cognitive ability in men. Differences in cognitive ability among the three cohorts were small and primarily reflected demographic differences. Discussion: Late-midlife cognitive ability is associated with a number of demographic factors, and demographic differences may contribute to individual differences in health and early aging. In analyses of cognitive ability, the three CAMB cohorts can be combined provided the relevant demographic variables are included as covariates.

Published: March 2014

Objectives: To investigate tobacco and alcohol consumption as risk indicators for missing teeth in late middle-aged Danes. Method: In all, 1,517 Copenhagen Aging and Midlife Biobank (CAMB) participants received a clinical oral examination that included number of teeth. Information on smoking, drinking, and various covariates was obtained using self-administered, structured questionnaires. Descriptive statistics and logistic regression (dependent variable: 6+ vs. <6 missing teeth) were used to investigate smoking and drinking in relation to missing teeth. Results: Current smokers, persons who currently or previously smoked >15 tobacco units/day, and persons who had smoked for 27+ years had elevated mean scores of missing teeth and associated odds ratios (OR) compared with never smokers. Relative to nondrinkers, alcohol consumption was associated with reduced odds of missing 6+ teeth. Discussion: Our findings suggest that smoking is positively associated, while alcoholic beverage consumption is inversely related to tooth loss in middle-aged Danes.

Published: March 2014

Objective: The aim of the present article is to describe the face and content validity as well as reliability of the Copenhagen Social Relations Questionnaire (CSRQ). Method: The face and content validity test was based on focus group discussions and individual interviews with 31 informants. Another 94 men and women participated in an 8-day test–retest analysis. Results: Informants generally expressed that the questions and response categories were relevant and easy to understand. Themes on structure of social relations, social support, and negative aspects of social relations emerged clearly from the interviews. Two additional themes not covered by CSRQ on dynamics and reciprocity of social relations were identified. Discussion: CSRQ holds satisfactory face and content validity as well as reliability, and is suitable for measuring structure and function of social relations including the negative aspects among middle-aged individuals.

Published: March 2014

Objectives: To analyze associations in late midlife between sex, age, education and social class, and the Big Five personality traits; to analyze associations between personality traits and cognitive ability in late midlife; and to evaluate how these associations are influenced by demographic factors. Methods: The study sample comprised 5,397 late midlife participants from three cohorts who had completed the NEO Five-Factor Inventory (NEO-FFI) and a measure of cognitive ability. Results: Associations were demonstrated between the five NEO-FFI personality traits, and all included demographic factors. Cognitive ability and years of education correlated with several NEO-FFI personality traits in analyses adjusting for demographic variables. Cohort differences were observed for Extraversion and Openness. Discussion: Robust sex, educational, and social class differences in personality may contribute to late midlife social gradients in health and early aging. Demographic factors did not fully explain correlations between personality and cognitive ability or cohort differences in personality.

Published: March 2014

Objective: To present the Danish Occupational Social Class (DOSC) measurement as a measure of socioeconomic position (SEP) applicable in a late midlife population, and to analyze associations of this measure with three aging-related outcomes in midlife, adjusting for education. Method: Systematic coding procedures of the DOSC measurement were applied to 7,084 participants from the Copenhagen Aging and Midlife Biobank (CAMB) survey. We examined the association of this measure of SEP with chronic conditions, self-rated health, and mobility in logistic regression analyses, adjusting for school education in the final analysis. Results: The measure of SEP showed a strong social gradient along the social classes in terms of prevalence of chronic conditions, poor self-rated health, and mobility limitations. Adjusting for school education attenuated the association only to a minor degree. Discussion: The DOSC measure was associated with aging-related outcomes in a midlife Danish population, and is, thus, well suited for future epidemiological research on social inequalities in health and aging.
Discrepancy Between Chronological Age and Felt Age
Authors: Choi Namkee G. , DiNitto Diana M. , Kim Jinseok
Published: March 2014

Objective: Guided by the social comparison theory, we examined correlates of the discrepancy between chronological and felt ages in three age groups of community-dwelling older adults: 65 to 69, 70 to 79, and 80 and older. Method: Data from the National Health and Aging Trends Study and linear regression models were used to test the hypothesis that age discrepancy would be significantly associated with objective health indicators among those in the 65 to 69 and 70 to 79 age groups but not among the 80+ group. Results: Objective health indicators were significantly associated with age discrepancy only in the 70 to 79 age group, while subjective health perceptions and psychological well-being were significantly associated with age discrepancy in all age groups. Discussion: The correlates of the discrepancy in the 65 to 69 age group appear to resemble those in the 80+ group more than those in the 70 to 79 age group. Further research is needed to identify the determinants of age group differences.

Authors: Guo Binghua , Zhang Yanli , Chen Lei , Yu Junrong , Zhu Jing , Hu Zuming
Published: March 2014

A series of polyimide (PI) copolymers were synthesized via a one-step polycondensation procedure from benzophenone-3,3′,4,4′-tetracarboxylic acid dianhydride, toluene diisocyanate (TDI), and 4,4′-methylene bis(phenyl isocyanate) (MDI) with various mole ratios of TDI and MDI ranging from 70:30 to 100:0. The inherent viscosities of the resulting PIs were in the range of 0.51–0.80 dL g−1. The prepared PIs showed good solubility in common organic as well as in less polar solvents. All copolymers afforded tough and flexible films that had good thermal stability with glass transition temperature of 308–325°C and the temperatures of 5% weight loss in air and nitrogen being 420 and 460°C, respectively. The resultant PI films with thickness about 15 μm exhibited high transparency (>88%) in visible region (400–700 nm). Also, the cured PI films possessed good mechanical properties with tensile strength of 60.52–69.31 MPa and tensile modulus of 0.98–1.30 GPa.
Reconfiguring machines to achieve system adaptability and sustainability: A practical case study
Authors: Bi Zhuming , Pomalaza-Ráez Carlos , Singh Zaadvinder , Nicolette-Baker Alexis , Pettit Blake , Heckley Cameron
Published: March 2014

The fierce competition in the global manufacturing environment is forcing enterprises to seek competitiveness beyond traditional aspects such as functions, quality, cost, and lead time. An emerging strategy is to develop sustainable manufacturing systems. An ideal sustainable system has the characteristics of remanufacturing, redesigning, recovering, reusing, recycling, and reducing. However, this type of sustainability mainly refers to the products rather than to the manufacturing system itself. When the design and operation of a manufacturing system are concerned, the criterion of sustainability often conflicts with other requirements such as cost and lead time. Instead of establishing a total new system paradigm, it is more realistic that the concept of sustainable manufacturing is used as a guidance to evolve existing systems to an advanced level. In this article, a case study is introduced to recycle an obsolete test machine to meet new functional requirements; it has shown a significant economic benefit. The presented case study provides a new perspective of economically evolving dedicated machines or manufacturing systems into sustainable systems.

Published: March 2014

Surface roughness is an important parameter that determines the post-manufacturing product quality. In this study, effect of cutting parameters, coating material and the built-up edge phenomenon on the surface roughness were investigated in micro end milling process of Inconel 718 using a white light interferometer and scanning electron microscopy. A micro end mill with a diameter of 768 µm coated with five separate coating materials (AlTiN, AlCrN, TiAlN + AlCrN, TiAlN + WC/C and diamond-like carbon) was used in this study. According to the results obtained, mean surface roughness values of surfaces machined with a diamond-like carbon-coated and AlTiN-coated cutting tool were lower than for other coatings. However, surface roughness values of surfaces obtained with tools coated with TiAlN + AlCrN and AlCrN were higher. Specifically, the formation of built-up edge causes chips to be smeared on machined surfaces, which has a negative impact on the surface quality. As can be expected, wear occurs faster on uncoated tools. As a result of this, the edge radius may increase excessively, and the mean surface roughness value may decrease. Also in this study, multivariate analysis of variance was carried out and the parameter that was most effective on surface roughness was established.
Communicating science in public controversies: Strategic considerations of the German climate scientists
Authors: Post Senja
Published: March 2014

In public controversies on scientific issues, scientists likely consider the effects of their findings on journalists and on the public debate. A representative survey of 123 German climate scientists (42%) finds that although most climate scientists think that uncertainties about climate change should be made clearer in public they do not actively communicate this to journalists. Moreover, the climate scientists fear that their results could be misinterpreted in public or exploited by interest groups. Asking scientists about their readiness to publish one of two versions of a fictitious research finding shows that their concerns weigh heavier when a result implies that climate change will proceed slowly than when it implies that climate change will proceed fast.
Men’s netball or gender-neutral netball?
Authors: Tagg Brendon
Published: March 2014

In this article I examine whether justice in New Zealand is better served through the provision of gender-inclusive or gender-segregated men’s netball competitions (where netball began as a late 19th century women’s version of basketball). While the New Zealand Men’s Netball Association (henceforth called the ‘men’s association’) was initially established in 1984 under an inclusive ethos rooted in Māori community-based and fa’afafine1-based competitions, by the end of that most overtly transgender and fa’afafine players were excluded so as to boost the association’s heterosexist credentials. This process culminated in 2004 when the men’s association was replaced by the New Zealand Men’s and Mixed Netball Association (henceforth called the ‘mixed association’). While in principle medically verified postoperative transgender women may now play in mixed-gender leagues, virtually none do. Furthermore, anyone who foregoes such treatment – including fa’afafine – must dress as a man in order to play. If it is the coercion that makes coercive gender segregation problematic then perhaps justice would be best served if men’s netball was a gender-neutral activity. This seems consistent with the gendered history of both netball and men’s netball in New Zealand.

The Silkie is a typical Chinese breed of chicken. In 2012, batches of Silkies were found to have diffuse tumor-like nodules on their skin after feather removal, when they were slaughtered at about 60 days old. Gross examination showed no visible neoplastic lesions on the visceral organs and peripheral nerves, except slight splenomegaly in individual chickens. The disease was prevalent, with high condemnation rates for skin lesions, which caused great economic losses to the company. Tissues, including skin, visceral organs, and peripheral nerves, were collected for histologic examination. Heparinized blood samples were collected for virus isolation and identification. Marek’s disease virus (MDV), Reticuloendotheliosis virus (REV), and Avian leukosis virus (ALV) were analyzed, using polymerase chain reaction (PCR) tests. Histologic examination showed that all of the tumor-like nodules on the skin were lymphomas. Lymphoproliferative lesions occurred mostly on the skin and only a few on the viscera, including the liver and proventriculus. Infected chick embryo fibroblasts showed clear cytopathic effects; indirect fluorescent antibody test for envelope glycoprotein B was positive. In addition, PCR indicated the presence of MDV serotype 1 infection without REV and ALV. A phylogenetic tree of the Meq gene showed that the isolate (SD121201) and Chinese reference strains, which are very virulent MDVs, are in the same clade. It was concluded that the Silkies tested were infected with MDV serotype 1. The Marek’s disease epidemic has been controlled using CVI988/Rispens vaccines.

A disintegrin-like and metalloprotease with thrombospondin type 1 repeat motifs 13 (ADAMTS13) is a von Willebrand factor (vWF)-cleaving protease. Deficiencies in ADAMTS13 activity are known to cause thrombotic diseases in human beings. The present study evaluated whether the human ADAMTS13 activity enzyme-linked immunosorbent assay (ELISA) kit containing human vWF73 (a minimal substrate) and anti-N10 antibody (which specifically recognizes the decapeptide of the C-terminal edge of cleaved vWF by human ADAMTS13) is applicable to the measurement of canine plasma ADAMTS13 activity. Human vWF73 fused with a GST-tag and a His-tag (GST-hvWF73-His) was reacted with recombinant canine (rc)ADAMTS13, canine plasma, and human plasma, and then used in Western blotting using anti-N10 antibody. Linearity and intra- and interassay reproducibility of the human ADAMTS13 activity ELISA kit in canine plasma were further evaluated. Finally, plasma ADAMTS13 activity was measured in 13 healthy dogs and 6 dogs with bacteremia using the human ADAMTS13 activity ELISA kit. Cleaved products with a 28-kDa GST-hvWF73-His were detected specifically in rcADAMTS13 as well as in human ADAMTS13, and also in canine plasma by anti-N10 antibody, showing excellent linearity. Intra-assay coefficient of variation (CV) was 3.0–12.4%, and interassay CV was 11.5–12.5%. The ADAMTS13 activity was significantly lower in dogs with bacteremia than in healthy dogs ( P = 0.0025). The current study revealed that the human ADAMTS13 activity ELISA kit is applicable for measurement of canine plasma ADAMTS13 activity to elucidate the pathology of thrombotic diseases in dogs.
Applying Ecological Modeling to Parenting for Australian Refugee Families
Authors: Grant Julian , Guerin Pauline B.
Published: March 2014

Children in families with parents from refugee backgrounds are often viewed as a vulnerable group with increased risks of developing physical or psychological problems. However, there is very little research regarding the strategies that parents might use to parent their children in a new country while they also manage the interrelated challenges of poverty, social isolation, maternal stress, and mental ill health that often go along with resettlement. We explore the application of ecological modeling, specifically at individual, institutional, and policy levels, within an Australian context to critique the factors that shape the development of parenting capacity within refugee families settling in a new Western country. Ecological modeling enables examination of how public policy at local state and national levels influences the individual and family directly and through the organizations that are given the task of implementing many of the policy recommendations. Recommendations for health practice and research are made.
The Effects of an Instructional Intervention on Racial Attitude Formation in Occupational Therapy Students
Authors: Steed Robin
Published: March 2014

The purpose of this pilot study was to examine the effect of a 9-week instructional intervention designed to increase 24 Caucasian American occupational therapy students’ awareness of personal racial attitudes toward African Americans. The learning content focused on specific cognitive-perceptual biases thought to play a role in the formation of racial attitudes. A pre- to posttest implicit measure of racial bias indicated an increase in bias in some students following the intervention and a decrease of bias in others. Students’ perception of the instruction and subsequent stereotype activation are discussed as possible moderators of the intervention’s effectiveness. Several implications for future instruction and research are suggested to address factors that may limit antibias instruction.
One Woman’s Empowerment Is Another’s Oppression
Authors: DeSouza Ruth
Published: March 2014

Purpose: To critically analyze the power relations underpinning New Zealand maternity, through analysis of discourses used by Korean migrant mothers. Design: Data from a focus group with Korean new mothers was subjected to a secondary analysis using a discourse analysis drawing on postcolonial feminist and Foucauldian theoretical ideas. Results: Korean mothers in the study framed the maternal body as an at-risk body, which meant that they struggled to fit into the local discursive landscape of maternity as empowering. They described feeling silenced, unrecognized, and uncared for. Discussion and Conclusions: The Korean mothers’ culturally different beliefs and practices were not incorporated into their care. They were interpellated into understanding themselves as problematic and othered, evidenced in their take up of marginalized discourses. Implications for Practice: Providing culturally safe services in maternity requires considering their affects on culturally different women and expanding the discourses that are available.
