Testing a Mobile Platform for Community Co‐Created Exhibitions
Authors: Rogers Alexandra , Rock Jenny 
Published: October 2017

AbstractThe benefits of co‐creation between museums and their communities are increasingly acknowledged but challenges remain in creating opportunities for and facilitating enactments of co‐creation. Time, funding and supporting infrastructure are significant hurdles. This study addresses the latter in describing a mobile platform designed for hosting community co‐created exhibitions. It assesses its functionality in two case studies where installations of the platform were hosted by major public museums in New Zealand. Both exhibitions had marine themes, but the co‐creation partners varied from a science education centre and their citizen science collaborators, to an informal group of adults and students engaged in water quality monitoring. Reflective evaluation of the co‐creative process using the platform revealed one of its major benefits to be its professional aesthetic, which allowed work to be presented to a high standard of display, and empowered co‐creators to feel confident in the quality of their work. Further success arose from its physical constraints; a practical scope for exhibitions was demarcated by certain structural limitations and offered relief from what was initially experienced by novice co‐creators as an intimidating amount of freedom within undefined space. Successful elements combined to facilitate key criteria for co‐creation including early and continuous empowerment and co‐ownership between co‐creating parties.
The Sweet Spot? Writing for a Reading Age of 12
Authors: Blunden Jennifer 
Published: October 2017

AbstractWriting for a reading age of 12 (or Reading Grade Level of 6 to 7) has long been considered a benchmark for accessible writing, the ‘sweet spot’ we should aim for to ensure our texts are accessible to a broad public audience. But what does a reading age of 12 actually mean and is it still useful as a guiding principle? This paper turns to emerging research in the field of academic literacies to review the concept of a reading age of 12 and consider what accessibility means in terms of language. It shows that while the idea of a 12‐year‐old as a benchmark has value, the basis on which it is typically determined is unhelpful if not misleading, and argues for an alternative approach based on meaning. It uses this approach to propose some practical strategies for understanding the key differences between everyday and academic language so that as authors, curators, educators, editors and publishers we can reach our audiences with greater inclusiveness and effectiveness.
Labor Density and Wages in Spain: Evidence from Geographically Disaggregated Data
Authors: Díaz Dapena Alberto , Fernández Vázquez Esteban , Rubiera Morollón Fernando 
Published: October 2017

AbstractIn this paper, Ciccone's () approach is applied to the Spanish case in 2011 but by estimating it using local labor markets (LLMs) instead of NUTS‐2 or NUTS‐3 regions. It is especially relevant in the case of Spain because the NUTS‐3 (provinces) are large regions in comparison with other cases in Europe. From a sample of income taxpayers published by the Spanish Fiscal Studies Institute, we derive figures on average wages by worker on the scale of LLMs. We argue that working at this level of spatial disaggregation is more in line with the idea of externalities from agglomerations, which are generated on a local scale. We can also observe intra‐regional heterogeneity and how the urban wage premium changes along the entire distribution of cities, including small‐medium size urban areas or rural areas. The empirical analysis is based on several estimation strategies, namely, ordinary least squares, two‐stages least squares, quantile regressions (QR), and instrumental variable quantile regressions (IVQR) estimators; they all find a significantly positive effect of agglomeration in the conditional mean of wages. This result can be estimated along the conditional distribution of wages. According to the QR and IVQR estimates, important variations are found along the distribution.

Published: October 2017

AbstractGraphene/silicon nitride (GR/Si3N4) ceramic composites with uniformly dispersed GR sheets were prepared using spark plasma sintering. The effects of GR content on the microstructure and electrical properties of the composites were investigated in detail. With the GR content rising, the conductive GR network was formed in the composites, leading to the appearance of a percolation phenomenon, and the conductive mechanism also changed from hopping conductivity to metal‐like conductivity. When the GR content reached the percolation threshold, the composites showed a negative permittivity behavior, which resulted from the low frequency plasmonic state generated by the formative conducting GR networks. The increasing GR content resulted in a higher plasma frequency and larger magnitude of negative permittivity, which was consistent with the analysis of Drude model. A relatively high dielectric loss was observed in the composites and mainly induced by the high leakage current among GR sheets. Our work is beneficial to expound the regulation mechanism of negative permittivity, and the obtained ceramic composites present some potential applications in microwave absorption, shielding and capacitors.
Unshrouding: Evidence from Bank Overdrafts in Turkey
Authors: ALAN SULE , CEMALCILAR MEHMET , KARLAN DEAN , ZINMAN JONATHAN 
Published: October 2017

ABSTRACTLower prices produce higher demand… or do they? A bank's direct marketing to holders of “free” checking accounts shows that a large discount on 60% APR overdrafts reduces overdraft usage, especially when bundled with a discount on debit card or autodebit transactions. In contrast, messages mentioning overdraft availability without mentioning price increase usage. Neither change persists long after the messages stop. These results do not square easily with classical models of consumer choice and firm competition. Instead, they support behavioral models where consumers underestimate and are inattentive to overdraft costs, and firms respond by shrouding overdraft prices in equilibrium.
A Mixed‐Methods Comparison of Classroom Context During Food, Health & Choices, a Childhood Obesity Prevention Intervention
Authors: Burgermaster Marissa , Koroly Jenna , Contento Isobel , Koch Pamela , Gray Heewon L. 
Published: October 2017

ABSTRACTBACKGROUNDSchools are frequent settings for childhood obesity prevention; however, intervention results are mixed. Classroom context may hold important clues to improving these interventions.METHODSWe used mixed methods to examine classroom context during a curriculum intervention taught by trained instructors in fifth grade classrooms. We identified classrooms with high and low buy‐in using cluster analysis and compared intervention delivery and reception, student energy balance‐related behavior, and student perceptions about supports and barriers to energy balance.RESULTSDelivery and reception did not differ between the groups. Between‐group differences in unhealthy behaviors were smaller at posttest, due to improvement in low buy‐in classes. Although student perceptions of supports and barriers to energy balance were similar across groups, students in high buy‐in classes indicated food preferences as a support while students in low buy‐in classes indicated food preferences as a barrier. Neighborhood environment emerged as a universal barrier.CONCLUSIONSTrained instructors may improve intervention delivery and reception regardless of classroom context. Social norms could explain high levels of unhealthy behavior in low buy‐in classes at baseline; improvement at posttest suggests that the curriculum may have motivated change. All children need more strategies and supportive policies to overcome a challenging food environment.

Published: October 2017

ABSTRACTBACKGROUNDPeer harassment can have serious implications for students' success and well‐being, and prevention programs need to consider the school context. This study aimed to: (1) identify groups of similar schools based on their risk and protective factors and demographic characteristics and (2) examine associations between school profiles and students' bullying involvement.METHODSData came from 505 schools and 122,106 students who completed the 2013 Minnesota Student Survey. School‐level risk and protective factors and demographic characteristics were included in a latent profile analysis (LPA) to identify profiles of schools. Multilevel logistic regression was used to assess associations between school profiles and peer harassment.RESULTSSix qualitatively different school profiles were identified. Unadjusted models showed that schools with higher levels of risk had greater odds of peer harassment. However, after controlling for student‐level risk and protection, regardless of school‐level risk, students in metro‐area schools with a more diverse student body reported lower odds of bullying involvement.CONCLUSIONSThese findings highlight the importance of the social environment into peer harassment. In addition to addressing student‐level risk and protection, larger community factors and norms also need to be taken into account for developing, selecting, and implementing the most effective approaches to bullying prevention.

Published: October 2017

ABSTRACTBACKGROUNDTeen pregnancy rates and related risks remain elevated among Latino teens. We tested the impact on youth sexual behaviors of a brief, culturally targeted, bilingual media intervention designed for parents of young adolescents.METHODSSalud y éxito (Health & Success) uses dramatic audio stories to model positive parenting practices. After completing classroom surveys, 27 urban schools in the Northeast and Southwest serving low‐income Latino communities were randomized so that all families of seventh grade students were sent either: (1) booklets on healthy eating and exercise; (2) Salud‐50, where families either received booklets or the intervention, or (3) Salud‐100, where all families received the intervention. Postintervention follow‐up surveys were conducted at 3‐ and 12‐months. Multilevel analyses tested intervention effects, controlling for sociodemographics.RESULTSCompared with controls, at 12‐months postintervention (8th grade spring), youth in Salud‐100 report lower sexual risks (touching, AOR 1.46, CI 1.19‐0.84, p < .001; lifetime sex (AOR 0.74, CI 0.61‐0.90, p < .01); and sex intentions (AOR 0.78, CI 0.63‐0.96, p < .05). Consistent with a dose‐response, Salud‐50 results are between those from Salud‐100 and control schools.CONCLUSIONSSalud y éxito is an effective parenting intervention that can augment school‐based health and sexuality education and help Latino parents support their children during early adolescence.

Published: October 2017

ABSTRACTBACKGROUNDThe Healthy, Hunger‐Free Kids Act of 2010 (HHFKA) directed the US Department of Agriculture (USDA) to revise school meal standards. Students are most affected by efforts to improve the school food environment; yet, few studies directly include students. This study examined high school students' experiences of school meal reform to gain insight into implementation recommendations.METHODSWe conducted 5 focus groups with high school students (N = 15) from high schools across 9 states. We also conducted follow‐up interviews to further explore personal experiences. Focus groups and interview transcripts were coded and organized in Atlas.ti v7 by analysts, following principles of constant comparative analysis.RESULTSStudents reported overall positive perceptions of the revised school meal standards and supported continued efforts to improve the food environment. Recommendations to improve the food environment included engaging students, focusing on the quality and palatability of meal items, moving toward scratch‐cooking, and addressing cafeteria infrastructure.CONCLUSIONSStudents' recommendations point to opportunities where school districts, as well as local, state, and federal organizations can work to improve the school food environment. Their insights are directly relevant to USDA's recently released Local School Wellness Policy final rule, of which school meal standards are one provision.
Weight gain during incarceration: systematic review and meta‐analysis

Published: October 2017

SummaryBackgroundExisting evidence suggests that the prevalence of overweight and obesity among prisoners in different settings is high. Evaluating weight change during incarceration would allow for the investigation of whether the prison environment indeed contributes to unfavourable weight changes.ObjectivesThis study aimed to do a systematic review and a meta‐analysis of existing evidence regarding weight change during incarceration.Methods and resultsWe conducted a systematic literature search by using five different online databases and included grey literature. A total of 16 studies, all conducted in developed countries, were identified. Weight change was computed in 11 of these studies and was self‐reported in five studies. Only two studies included youth. In all but 1 of the 11 studies using actual assessment of weight change, there was an increase in body weight or body mass index on average or weight gain occurred among a significant proportion of participants. A meta‐analysis of eight of these studies showed an average weight gain of 0.43 (95% CI 0.14, 0.72) lb/week. In all studies including perceived weight change, a high proportion (43% to 73%) of participants reported weight gain during incarceration.ConclusionHealth promotion activities within prisons should incorporate initiatives aimed at combating unhealthy weight developments.

BACKGROUNDTransplantation of hematopoietic stem cells (HSCs) from peripheral blood (PB) or cord blood (CB) is well established. HSCs from CB are associated with a lower risk of graft‐versus‐host disease (GVHD), but antigen‐independent expanded CB‐ and PB‐derived T cells can induce GVHD in allo‐HSC recipients. CB‐derived cells might be more suitable for adoptive immunotherapy as they have unique T‐cell characteristics. Here, we describe functional differences between CB and PB T cells stimulated with different cytokine combinations involved in central T‐cell activation.STUDY DESIGN AND METHODSIsolated CD8+ T cells from CB and PB were stimulated antigen independently with anti‐CD3/CD28 stimulator beads or in an antigen‐dependent manner with artificial antigen‐presenting cells loaded with the HLA‐A*02:01‐restricted peptide of tumor‐associated melanoma antigen recognized by T cells 1 (MART1). CB and PB T cells cultured in the presence of interleukin (IL)‐7, IL‐15, IL‐12, and IL‐21 were characterized for T‐cell phenotype and specificity, that is, by CD107a, interferon‐γ, tumor necrosis factor‐α, and IL‐2 expression.RESULTSAfter antigen‐independent stimulation, activated CD8+ CB T cells exhibited stronger proliferation and function than those from PB. After antigenic stimulation, MART1‐reactive CB T cells were naïve (CD45RA+CCR7+), cytotoxic, and highly variable in expressing homing marker CD62L. Addition of IL‐21 resulted in increased T‐cell proliferation, whereas supplementation with IL‐12 decreased IL‐21–induced expansion, but increased the functionality and cytotoxicity of CB and PB T cells.CONCLUSIONMART1‐reactive CB T cells with a more naïve phenotype and improved properties for homing can be generated. The results contribute to better understanding the effects on GVHD and graft versus tumor.

Published: October 2017

AbstractLocoregional lymph nodes are routinely examined in order to define the spatial extent of neoplastic disease. As draining patterns of certain tumor types can be divergent from expected anatomical distribution, it is critical to sample the lymph nodes truly representing the draining area. The aim of this bicenter prospective pilot study was to describe the technique of computed tomographic (CT)‐lymphography for primary draining lymph node mapping in tumor staging in dogs. Forty‐five dogs with macro‐ or microscopic tumors in specified localizations were evaluated. Depending on body weight, 0.8–2 ml contrast agent (iohexol) was injected into four quadrants around the tumor, and CT‐images were obtained at 1, 3, 6, 9, and 12 minutes post‐injection. Attenuation of chosen regions of interest (Hounsfield units (HU)) and patterns of enhancement were assessed for 284 lymph nodes in the precontrast study with median HUs of 31.1 (Interquartile range (IQR) = 18.4) and for 275 in the intravenous postcontrast study with 104.3 HU (IQR = 31.2) (paired Wilcoxon test, P < 0.001). In the CT‐lymphography study, 45 primary draining lymph nodes with a significantly higher median HU value of 348.5 (IQR = 591.4) (one‐sample t‐test, P < 0.001) were identified. Primary draining lymph nodes were found to be clearly visible after 1–3 minutes after local injection, often concurrent with a good visibility of the lymphatic vessel system. The herein described technique of peritumorally injected CT‐contrast agent followed by subsequent CT‐lymphography for primary draining lymph node mapping works well in a majority of cases in all investigated sites and warrants further validation for different tumor entities.

To maintain blinding, participants were dosed twice 2 weeks apart; CVD 103-HgR recipients ingested placebo 2 weeks before or after ingesting vaccine. Seroconversion (a ≥4-fold vibriocidal titer rise) between the baseline and 14 days after CVD 103-HgR ingestion and following the first and second doses of Shanchol were the main outcomes measured. By day 14 postvaccination, the rates of seroconversion after ingestion of a single standard dose and a high dose of CVD 103-HgR were 71.7% (33/46 participants) and 83.3% (40/48 participants), respectively. The rate of seroconversion following the first dose of Shanchol, 56.0% (28/50 participants), was significantly lower than that following the high dose of CVD 103-HgR (
P
= 0.003). The vibriocidal geometric mean titer (GMT) of the high dose of CVD 103-HgR exceeded the GMT of the standard dose at day 14 (214 versus 95,
P
= 0.045) and was ∼2-fold higher than the GMT on day 7 and day 14 following the first Shanchol dose (
P
> 0.05). High-dose CVD 103-HgR is recommended for accelerated evaluation in developing countries to assess its efficacy and practicality in field situations. (This study has been registered at ClinicalTrials.gov under registration no. NCT02145377.)
