INVESTIGATION OF THE RELATIONS BETWEEN DOMAIN-SPECIFIC BELIEFS ABOUT WRITING, WRITING SELF-EFFICACY, WRITING APPREHENSION, AND WRITING PERFORMANCE IN UNDERGRADUATES

Writing has been called the "neglected `R'" in the traditional trilogy of reading, `riting, and `rithmetic (National Commission on Writing, 2003). Writing performance continues to languish, despite societal expectations that students should be able to write clearly and precisely. Sociocognitive theory predicts that writing beliefs are related to writing performance. Much research has focused on writing self-efficacy beliefs and their link to writing apprehension and writing performance, while research exploring another type of belief, domain-specific beliefs about writing itself, is sparse. This study examined the relations between these beliefs about writing, writing self-efficacy, and writing apprehension, and their links to writing performance. This research was a three-phase study. Phases I and II involved instrument construction and validation, while Phase III examined the relations among the research variables. Two hundred eighty-seven Hispanic women students completed a test battery in class measuring demographics, beliefs about writing, writing self-efficacy, and writing apprehension. Writing performance was measured separately on an authentic writing task, a take-home paper, by both an overall grade and six component grades. Inter-rater agreements on these grades ranged from r = .83 to .91. Hierarchical regression analyses revealed that beliefs about writing independently predicted writing performance and that some beliefs about writing (e.g., Good writers adapt their message to their readers) are adaptive and associated with strong writing performance, while other beliefs about writing (e.g., Readers are impressed by big words) are maladaptive and relate to weak writing performance. In addition, apprehension about making grammatical and other mechanical errors had a stronger negative effect on writing performance than the more traditional concept of writing apprehension, which concerns sharing one's writing with others and having it critiqued. After controlling for domain-specific beliefs, writing self-efficacy weakly predicted writing performance as well. These results support the need for future research examining the relations among the research variables and writing performance in samples that are more balanced with respect to gender and ethnicity, and with other writing tasks. Because beliefs about writing demonstrated the largest beta weights in the regression equations, these beliefs may have the most promise for promoting both writing research and practice

Social networks, work and network-based resources for the management of long-term conditions: a framework and study protocol for developing self-care support

Background: increasing the effective targeting and promotion of self-care support for long-term conditions requires more of a focus on patient contexts and networks. The aim of this paper is to describe how within a programme of research and implementation, social networks are viewed as being centrally involved in the mobilisation and deployment of resources in the management of a chronic condition. This forms the basis of a novel approach to understanding, designing, and implementing new forms of self-management support.Methods: drawing on evidence syntheses about social networks and capital and the role of information in self-management, we build on four conceptual approaches to inform the design of our research on the implementation of self-care support for people with long-term conditions. Our approach takes into consideration the form and content of social networks, notions of chronic illness work, normalisation process theory (NPT), and the whole systems informing self-management engagement (WISE) approach to self-care support.Discussion: the translation and implementation of a self-care agenda in contemporary health and social context needs to acknowledge and incorporate the resources and networks operating in patients' domestic and social environments and everyday lives. The latter compliments the focus on healthcare settings for developing and delivering self-care support by viewing communities and networks, as well as people suffering from long-term conditions, as a key means of support for managing long-term conditions. By focusing on patient work and social-network provision, our aim is to open up a second frontier in implementation research, to translate knowledge into better chronic illness management, and to shift the emphasis towards support that takes place outside formal health services.<br/

The LINC00961 transcript and its encoded micropeptide SPAAR regulate endothelial cell function

AIMS: Long non-coding RNAs (lncRNAs) play functional roles in physiology and disease, yet understanding of their contribution to endothelial cell (EC) function is incomplete. We identified lncRNAs regulated during EC differentiation and investigated the role of LINC00961 and its encoded micropeptide, small regulatory polypeptide of amino acid response (SPAAR), in EC function. METHODS AND RESULTS: Deep sequencing of human embryonic stem cell differentiation to ECs was combined with Encyclopedia of DNA Elements (ENCODE) RNA-seq data from vascular cells, identifying 278 endothelial enriched genes, including 6 lncRNAs. Expression of LINC00961, first annotated as an lncRNA but reassigned as a protein-coding gene for the SPAAR micropeptide, was increased during the differentiation and was EC enriched. LINC00961 transcript depletion significantly reduced EC adhesion, tube formation, migration, proliferation, and barrier integrity in primary ECs. Overexpression of the SPAAR open reading frame increased tubule formation; however, overexpression of the full-length transcript did not, despite production of SPAAR. Furthermore, overexpression of an ATG mutant of the full-length transcript reduced network formation, suggesting a bona fide non-coding RNA function of the transcript with opposing effects to SPAAR. As the LINC00961 locus is conserved in mouse, we generated an LINC00961 locus knockout (KO) mouse that underwent hind limb ischaemia (HLI) to investigate the angiogenic role of this locus in vivo. In agreement with in vitro data, KO animals had a reduced capillary density in the ischaemic adductor muscle after 7 days. Finally, to characterize LINC00961 and SPAAR independent functions in ECs, we performed pull-downs of both molecules and identified protein-binding partners. LINC00961 RNA binds the G-actin sequestering protein thymosin beta-4x (Tβ4) and Tβ4 depletion phenocopied the overexpression of the ATG mutant. SPAAR binding partners included the actin-binding protein, SYNE1. CONCLUSION: The LINC00961 locus regulates EC function in vitro and in vivo. The gene produces two molecules with opposing effects on angiogenesis: SPAAR and LINC00961

A Classification System for Defining and Estimating Dietary Intake of Live Microbes in US Adults and Children

Background: Consuming livemicrobes in foods may benefit human health. Live microbe estimates have not previously been associated with individual foods in dietary databases. Objectives: We aimed to estimate intake of live microbes in US children (aged 2–18 y) and adults (≥19 y) (n = 74,466; 51.2% female). Methods: Using cross-sectional data from the NHANES (2001–2018), experts assigned foods an estimated level of live microbes per gram [low (Lo), \u3c104 CFU/g; medium (Med), 104–107 CFU/g; or high (Hi), \u3e107 CFU/g]. Probiotic dietary supplements were also assessed. The mean intake of each live microbe category and the percentages of subjects who ate from each live microbe category were determined. Nutrients from foods with live microbes were also determined using the population ratio method. Because the Hi category comprised primarily fermented dairy foods, we also looked at aggregated data for Med or Hi (MedHi), which included an expanded range of live microbe–containing foods, including fruits and vegetables. Results: Our analysis showed that 52%, 20%, and 59% of children/adolescents, and 61%, 26%, and 67% of adults, consumed Med, Hi, or MedHi foods, respectively. Per capita intake of Med, Hi, and MedHi foods was 69, 16, and 85 g/d for children/adolescents, and 106, 21, and 127 g/d for adults, respectively. The proportion of subjects who consumed live microbes and overall per capita intake increased significantly over the 9 cycles/18-y study period (0.9–3.1 g/d per cycle in children across categories and 1.4 g/d per cycle in adults for the Med category). Conclusions: This study indicated that children, adolescents, and adults in the United States steadily increased their consumption of foods with live microbes between the earliest (2001–2002) and latest (2017–2018) survey cycles. Additional research is needed to determine the relations between exposure to live microbes in foods and specific health outcomes or biomarkers

Regional Heterogeneity in Murine Lung Fibroblasts from Normal Mice or Mice Exposed Once to Cigarette Smoke

Chronic obstructive lung disease (COPD) is characterized by matrix deposition in the small airways but matrix loss from the parenchyma, phenomena which must depend on the ability of local fibroblasts to produce matrix after smoke exposure. To investigate this idea, we exposed C57Bl/6 mice once to cigarette smoke or to air (control) and prepared primary cultures of lung fibroblasts by microdissecting large airways (trachea, LAF), medium size airways (major bronchi, MAF) and parenchyma (PF). Control PF showed the lowest rate of wound closure and wound closure was depressed in all lines by a single in vivo smoke exposure. Gene expression of matrix proteins differed considerably among the sites; decorin, which may sequester TGFβ, was markedly higher in PF. PF showed higher intrinsic ratios of pSmad2/Smad2. Smoke caused much greater increases in secreted and matrix deposited collagens 1 and 3 in PF than in LAF or MAF. Expression of Thy-1, a gene that suppresses myofibroblast differentiation, was increased by smoke in PF. We conclude that there is considerable regional heterogeneity in murine lung fibroblasts in terms of matrix production, either basally or after in vivo smoke exposure; that PF have lower ability to repair wounds and higher intrinsic TGFβ signaling; and that a single exposure to smoke produces lasting changes in the pattern of matrix production and wound repair, changes that may be mediated in part by smoke-induced release of TGFβ. However, PF still retain the ability to repair by producing new matrix after a single in vivo smoke exposure

Involving individuals with disorders of sex development and their parents in exploring new models of shared learning: Proceedings from a DSDnet COST Action workshop

The level of connection between health care professionals and people who experience a condition that affects sex development is variable. These people and associated support groups need to be included in discussions about research and healthcare delivery. The aim of this study was to understand the experiences of individuals with disorders of sexual development (DSD), their parents, health care providers, and support groups. Workshop planning, preparation, delivery, and evaluation involved members of working groups from the COST Action DSDnet. A coordinator, in collaboration with a support group representative, led the workshop design and delivery. Our successful, facilitated workshop involved 33 attendees from 8 EU countries. The workshop provided individuals with DSD, parents, advisory groups, and professionals with an opportunity for shared learning. Outputs focused on 7 key areas, including diagnosis, childhood, and transition to adult care as well as fostering discussion around registries, future research topics, consent processes, and information needs across the life course. The importance of trustworthy and knowledgeable providers, time to understand such rare conditions, and the place support groups have in a life course approach were valuable learning points for all attendees. In conclusion, workshops can be designed and delivered in meaningful ways for all those involved in care of individuals with rare conditions

Child and parent outcomes following parent interventions for child emotional and behavioral problems in autism spectrum disorders: A systematic review and meta-analysis

There is growing interest in the development of behavioral parent interventions targeting emotional and behavioral problems in children with autism spectrum disorders. Such interventions have potential to improve a number of child and parental well-being outcomes beyond disruptive child behavior. This systematic review and meta-analysis assesses evidence for the efficacy of behavioral parent interventions for disruptive and hyperactive child behavior in autism spectrum disorders, as well as parenting efficacy and stress. A total of 11 articles from nine randomized controlled trials were included. Sufficient data were available to calculate standardized mean difference and show favorable effects of behavioral parent interventions on parent-reported measures of child disruptive behavior (standardized mean difference = 0.67), hyperactivity (standardized mean difference = 0.31) and parent stress (standardized mean difference = 0.37); effects on parent efficacy are less clear (standardized mean difference = 0.39, p = 0.17). There were insufficient data to explore intervention effects on internalizing behavior in autism spectrum disorders, parenting behaviors, or observational and teacher-reported outcomes, providing important avenues for future research. This review adds to growing evidence of the efficacy of behavioral parent interventions for child behavior and parental well-being in autism spectrum disorders (Prospero: CRD42016033979)
