Purpose In this qualitative study, school-age children between 7 and 11 years, living with a bleeding disorder or other chronic illness, defined how they understand their partnership role in family-centred care (FCC), and recommended FCC strategies. Methods This systematic ethnography had three phases: unstructured interviews explored how children understood FCC partnership roles (phase I); document review provided FCC institutional context (phase II); and validation interviews generated FCC partnership recommendations (phase III). This study took place within the area served by a Western Canadian children's hospital. Interviews were held at the hospital or children's home. In phase I, purposive sampling was used to recruit children receiving outpatient care for a bleeding disorder (n= 4) or another chronic illness (n= 4). In phase II, policies and legislation were compared with how children understand their FCC partnership role. In phase III, validation interviews were conducted with children (n= 3) to confirm domains and generate FCC supporting strategies. Data collection and analysis were based on domain analysis and qualitative ethnographic content analysis. Results Phase I outcomes included seven domains regarding how children understood their role as partners in FCC: my best interests, virtues, talking and listening, being involved, knowing, making decisions and being connected. Phase II outcomes revealed how these domains were represented in institutional contexts. Phase III outcomes confirmed domains and generated key strategies to support children's role as FCC partners through graphic representation of FCC as a treasure map, interactive workshop and online game. Conclusions School-age children, living with a bleeding disorder or other chronic illness, similarly want to learn how to be FCC partners by developing competence as healthcare team members, identifying their own best interests, learning how to communicate with 'grown-ups', clarifying roles and goals, and guided opportunities for decision making. Facilitating school-age children's FCC partnership roles is worthy to explore in youth transition programmes. © 2011 Blackwell Publishing Ltd.

Computing education has faced a variety of ongoing and critical self-examinations over the past 15 years. This paper provides a set of critiques and alternative teaching approaches for two vital but under-reported computing knowledge areas: web development and computing ethics/social issues. It concludes with a claim that these two knowledge areas can also provide an important way to integrate the often-heterogeneous knowledge areas in the computing curriculum. Copyright 2012 ACM.

Balance is an essential component of movement and is critical in the ability to participate in physical activity. Developing an exergaming curriculum for schools has the potential to improve balance or postural stability in children. In this study, a purposely-built exergaming center in an elementary school was used to test fourth grade students with a specially designed exergaming curriculum oriented towardimproving postural stability. The program was implemented over a 6-week period, 34minper day, 4-5 days per week. Two control groups were used: (1) a physical education (PE) class geared toward agility, balance, and coordination (ABC) improvement, and (2) a typical PE curriculum class. Exergaming students improved their postural stability significantly over a 6-week period compared to those in the typical PE class. Improvements in postural stability were also evident in the ABC class. Postural stability in the girls was better than the boys in all pre- and post-intervention tests. This study demonstrates that exergaming is a practical resource in the PE class to improve postural stability. © 2012 Shanghai University of Sport.

There is a growing interest in modulating gut microbiota with diet in the context of obesity. The purpose of the present study was to evaluate the dose-dependent effects of prebiotics (inulin and oligofructose) on gut satiety hormones, energy expenditure, gastric emptying and gut microbiota. Male lean and obese JCR:LA-cp rats were randomised to either of the following: lean 0 % fibre (LC), lean 10 % fibre (LF), lean 20 % fibre (LHF), obese 0 % fibre (OC), obese 10 % fibre (OF) or obese 20 % fibre (OHF). Body composition, gastric emptying, energy expenditure, plasma satiety hormone concentrations and gut microbiota (using quantitative PCR) were measured. Caecal proglucagon and peptide YY mRNA levels were up-regulated 2-fold in the LF, OF and OHF groups and 3-fold in the LHF group. Ghrelin O-acyltransferase mRNA levels were higher in obese v. lean rats and decreased in the OHF group. Plasma ghrelin response was attenuated in the LHF group. Microbial species measured in the Bacteroidetes division decreased, whereas those in the Firmicutes increased in obese v. lean rats and improved with prebiotic intake. Bifidobacterium and Lactobacillus increased in the OHF v. OC group. Bacteroides and total bacteria negatively correlated with percentage of body fat and body weight. Enterobacteriaceae increased in conjunction with glucose area under the curve (AUC) and glucagon-like peptide-1 AUC. Bacteroides and total bacteria correlated positively with ghrelin AUC yet negatively with insulin AUC and energy intake (P < 005). Several of the mechanisms through which prebiotics act (food intake, satiety hormones and alterations in gut microbiota) are regulated in a dose-dependent manner. The combined effects of prebiotics may have therapeutic potential for obesity. © The Authors 2011.

Television shows, such as CBS's CSI and its spin-offs CSI: Miami; CSI: Las Vegas; and CSI: New York, have sparked the imagination of thousands of viewers who want to become forensic scientists. The shows' fictional portrayals of crime scene investigations have prompted fears that jurors will demand DNA and other forensic evidence before they will convict, and have unrealistic expectations of that evidence. This has been dubbed the "CSI effect." This phenomenon was explored using results from a Canadian study based on 605 surveys of Canadian college students who would be considered jury-eligible and Australian quantitative and qualitative findings from a study that surveyed and interviewed real posttrial jurors. Information about the way jurors deal with forensic evidence in the context of other evidence and feedback about the way in which understanding such evidence could be increased were gained from both these studies. The comparison provides insights into the knowledge base of jurors, permitting adaptation of methods of presenting forensic information by lawyers and experts in court, based on evidence rather than folklore. While the Canadian juror data showed statistically significant findings that jurors are clearly influenced in their treatment of some forensic evidence by their television-viewing habits, reassuringly, no support was found in either study for the operation of a detrimental CSI effect as defined above. In the Australian study, in fact, support was found for the proposition that jurors assess forensic evidence in a balanced and thoughtful manner. © 2010 American Academy of Forensic Sciences.

This study investigates undergraduate perceptions of the social media technologies (SMTs) they use in their learning. This mixed methods inquiry employed 30 semi-structured interviews and an online survey (N = 679) to explore why and how undergraduates from across disciplines view SMTs to be a meaningful part of their university learning. Findings shed new insights into student perspectives on and uses of social media, and the variety of ways in which undergraduates intentionally choose (or, choose not) to incorporate social media into their university learning in meaningful ways. Student perceptions formed an overarching theme of social media as a double-edged sword that both informs and distracts, having the potential to both help and hinder learning. Together, the interviews and the open-ended survey results demonstrate that several contextual relationships exist, underscoring the importance of considering affordances of social media for learning. Rather than taking an approach founded upon technological determinism, learning context and social media affordances become key. Undergraduate perceptions of educational interactions via social media illustrate the prominence of student-student and student-content, rather than faculty-student, interactions via social media in their learning, allowing for an updated understanding of previous educational interactions models. © 2016 Elsevier Ltd

Background: Prospective memory (ProM) is the ability to become aware of a previously-formed plan at the right time and place. For over twenty years, researchers have been debating whether prospective memory declines with aging or whether it is spared by aging and, most recently, whether aging spares prospective memory with focal vs. non-focal cues. Two recent meta-analyses examining these claims did not include all relevant studies and ignored prevalent ceiling effects, age confounds, and did not distinguish between prospective memory subdomains (e.g., ProM proper, vigilance, habitual ProM) (see Uttl, 2008, PLoS ONE). The present meta-analysis focuses on the following questions: Does prospective memory decline with aging? Does prospective memory with focal vs. non-focal cues decline with aging? Does the size of age-related declines with focal vs. non-focal cues vary across ProM subdomains? And are age-related declines in ProM smaller than agerelated declines in retrospective memory? Methods and Findings: A meta-analysis of event-cued ProM using data visualization and modeling, robust count methods, and conventional meta-analysis techniques revealed that first, the size of age-related declines in ProM with both focal and non-focal cues are large. Second, age-related declines in ProM with focal cues are larger in ProM proper and smaller in vigilance. Third, age-related declines in ProM proper with focal cues are as large as age-related declines in recall measures of retrospective memory. Conclusions: The results are consistent with Craik's (1983) proposal that age-related declines on ProM tasks are generally large, support the distinction between ProM proper vs. vigilance, and directly contradict widespread claims that ProM, with or without focal cues, is spared by aging. © 2011 Bob Uttl.

ATP binding cassette (ABC) transporters play diverse roles, including lipid transport, in all kingdoms. ABCG subfamily transporters that are encoded as half-transporters require dimerization to form a functional ABC transporter. Different dimer combinations that may transport diverse substrates have been predicted from mutant phenotypes. In Arabidopsis thaliana, mutant analyses have shown that ABCG11/WBC11 and ABCG12/CER5 are required for lipid export from the epidermis to the protective cuticle. The objective of this study was to determine whether ABCG11 and ABCG12 interact with themselves or each other using bimolecular fluorescence complementation (BiFC) and protein traffic assays in vivo. With BiFC, ABCG11/ABCG12 heterodimers and ABCG11 homodimers were detected, while ABCG12 homodimers were not. Fluorescently tagged ABCG11 or ABCG12 was localized in the stem epidermal cells of abcg11 abcg12 double mutants. ABCG11 could traffic to the plasma membrane in the absence of ABCG12, suggesting that ABCG11 is capable of forming flexible dimer partnerships. By contrast, ABCG12 was retained in the endoplasmic reticulum in the absence of ABCG11, indicating that ABCG12 is only capable of forming a dimer with ABCG11 in epidermal cells. Emerging themes in ABCG transporter biology are that some ABCG proteins are promiscuous, having multiple partnerships, while other ABCG transporters form obligate heterodimers for specialized functions. © 2010 American Society of Plant Biologists.

STUDY DESIGN.: Delphi. OBJECTIVE.: Obtain an expert consensus on which history factors are most important in the clinical diagnosis of LSS. SUMMARY OF BACKGROUND DATA.: Lumbar spinal stenosis (LSS) is a poorly defined clinical syndrome. Criteria for defining LSS are needed and should be informed by the experience of expert clinicians. METHODS.: Phase 1 (Delphi Items): 20 members of the International Taskforce on the Diagnosis and Management of LSS confirmed a list of 14 history items. An on-line survey was developed that permits specialists to express the logical order in which they consider the items, and the level of certainty ascertained from the questions. Phase 2 (Delphi Study) Round 1: Survey distributed to members of the International Society for the Study of the Lumbar Spine. Round 2: Meeting of 9 members of Taskforce where consensus was reached on a final list of 10 items. Round 3: Final survey was distributed internationally. Phase 3: Final Taskforce consensus meeting. RESULTS.: 279 clinicians from 29 different countries, with a mean of 19 (±SD: 12) years in practice participated. The six top items were “leg or buttock pain while walking”, “flex forward to relieve symptoms”, “feel relief when using a shopping cart or bicycle”, “motor or sensory disturbance while walking”, “normal and symmetric foot pulses”, “lower extremity weakness” and “low back pain”. Significant change in certainty ceased after 6 questions at 80% (p?.05). CONCLUSIONS.: This is the first study to reach an international consensus on the clinical diagnosis of LSS, and suggests that within six questions clinicians are 80% certain of diagnosis. We propose a consensus-based set of “7 history items” that can act as a pragmatic criterion for defining LSS in both clinical and research settings, which in the long-term may lead to more cost-effective treatment, improved health-care utilization and enhanced patient outcomes.Level of Evidence: 2 Copyright © 2016 Wolters Kluwer Health, Inc.
