Conducting rigorous research with subgroups of at-risk youth: lessons learned from a teen pregnancy prevention project in Alaska

In 2010, Alaska Department of Health and Social Services (DHSS) received federal funding to test an evidence-based teen pregnancy prevention program. The grant required a major modification to an existing program and a randomized control trial (RCT) to test its effectiveness. As the major modifications, Alaska used peer educators instead of adults to deliver the program to youth aged 1419 instead of the original curriculum intended age range of 1214. Cultural and approach adaptations were included as well. After 4 years of implementation and data collection, the sample was too small to provide statistically significant results. The lack of findings gave no information about the modification, nor any explanation of how the curriculum was received, or reasons for the small sample. This paper reports on a case study follow-up to the RCT to better understand outcome and implementation results. For this study, researchers reviewed project documents and interviewed peer educators, state and local staff, and evaluators. Three themes emerged from the data: (a) the professional growth of peer educators and development of peer education, (b) difficulties resulting from curriculum content, especially for subpopulations of sexually active youth, youth identified as lesbian, gay, bisexual, transgender, queer, intersex and/or asexual, pregnant, and parenting youth and (c) the appropriateness of an RCT with subpopulations of at-risk youth. Three recommendations emerged from the case study. First, including as many stakeholders as possible in the program and evaluation design phases is essential, and must be supported by appropriate funding streams and training. Second, there must be recognition of the multiple small subpopulations found in Alaska when adapting programs designed for a larger and more homogeneous population. Third, RCTs may not be appropriate for all population subgroups.Ye

Rhizosphere Microbial Communities of \u3ci\u3eSpartina alternifloa\u3c/i\u3e and \u3ci\u3eJuncus roemerianus\u3c/i\u3e From Restored and Natural Tidal Marshes on Deer Island, Mississippi

The U. S. Gulf of Mexico is experiencing a dramatic increase in tidal marsh restoration actions, which involves planting coastal areas with smooth cordgrass (Spartina alterniflora) and black needlerush (Juncus roemerianus) for erosion control and to provide habitat for fish and wildlife. It can take decades for sedimentary cycles in restored marshes to approach reference conditions, and the contribution of the sediment microbial communities to these processes is poorly elucidated. In this study, we addressed this gap by comparing rhizosphere microbiomes of S. alterniflora and J. roemerianus from two restored marshes and a natural reference marsh located at Deer Island, MS. Our results revealed that plants from the restored and reference areas supported similar microbial diversity indicating the rapid colonization of planted grasses with indigenous soil microbiota. Although close in composition, the microbial communities from the three studied sites differed significantly in the relative abundance of specific taxa. The observed differences are likely driven by the host plant identity and properties of sediment material used for the creation of restored marshes. Some of the differentially distributed groups of bacteria include taxa involved in the cycling of carbon, nitrogen, and sulfur, and may influence the succession of vegetation at the restored sites to climax condition. We also demonstrated that plants from the restored and reference sites vary in the frequency of culturable rhizobacteria that exhibit traits commonly associated with the promotion of plant growth and suppression of phytopathogenic fungi. Our findings will contribute to the establishment of benchmarks for the assessment of the outcome of coastal restoration projects in the Gulf of Mexico and better define factors that affect the long-term resiliency of tidal marshes and their vulnerability to climate change

Repensando “Educación para la Salud”, desde el enfoque de Educación en salud y en contexto de pandemia

Educación para la salud fue incorporada como innovación curricular al Plan 1990 del Profesorado en Ciencias Biológicas de la UNC cuando la Carta de Ottawa encabezaba el cambio de paradigma. Habiendo transcurrido ya 30 años consideramos necesario la incorporación de miradas complejas y conceptos provenientes de múltiples campos del saber, abordar la salud de manera colectiva y la educación en salud como un posicionamiento político pedagógico respecto al campo (Martins, 2019). Así nos encontramos reprogramando esta asignatura, en contexto de pandemia y educación remota. Nos preguntamos ¿cómo la educación en salud podría ocuparse de transmitir modelos y herramientas para comprender y producir conocimientos nuevos, enriquecer o transformar las narraciones heredadas y pulir o descartar viejos procedimientos?. Consideramos fundamental cuestionar enfoques clásicos y desarrollar una mirada crítica y desafiante que habilite otras formas escolares y curriculares localmente contextualizadas, más justas e igualitarias (Fainsod y Busca, 2017). Para ello, no buscamos recrear el aula presencial en un entorno virtual sino revisar nuestras prácticas y reinventarnos (Maggio, 2020). Compartimos con les estudiantes recorridos abiertos en Genially y formatos diversos, habilitamos espacios para pensar e intercambiar sobre sus producciones entre todes, luego elaboran producciones como videos, infografías y podcast. Con esta propuesta nuestro objetivo es que puedan vivenciar experiencias formativas donde el conocimiento científico sea una construcción humana, un ámbito cultural atravesado por múltiples dimensiones, intereses e implicancias ético-sociales.publishedVersionFil: Biber, Priscila A.

On Being Negative

This paper investigates the pragmatic expressions of negative evaluation (negativity) in two corpora: (i) comments posted online in response to newspaper opinion articles; and (ii) online reviews of movies, books and consumer products. We propose a taxonomy of linguistic resources that are deployed in the expression of negativity, with two broad groups at the top level of the taxonomy: resources from the lexicogrammar or from discourse semantics. We propose that rhetorical figures can be considered part of the discourse semantic resources used in the expression of negativity. Using our taxonomy as starting point, we carry out a corpus analysis, and focus on three phenomena: adverb + adjective combinations; rhetorical questions; and rhetorical figures. Although the analysis in this paper is corpus-assisted rather than corpus-driven, the final goal of our research is to make it quantitative, in extracting patterns and resources that can be detected automatically

How Unpopular Policies are Made: Examples from South Africa, Singapore, and Bangladesh

In this article we contribute to the emerging knowledge on migration policy?making in two ways. Firstly, we address the relative lack of research on the gendered nature of migration policy?making. Secondly we contribute to understanding migration policymaking in postcolonial contexts. Based on case studies from Bangladesh, South Africa, and Singapore, we trace the drivers of policy change in these contexts and how the gendered vulnerability of the intended beneficiaries impacted the policy process. We found that there were four main drivers of migration policy?making in each of the countries. They were: the role?players in the policy change process, the debates that shaped the policy change, the research involved, and the political context in which the policy change took place. While our research drew on existing policy frameworks, it also showed that policy development is shaped by complex socio?political conditions.DFIDMigrating out of Povert

The aetiology of rickets-like lower limb deformities in Malawian children

Summary: Debilitating rickets-like lower limb deformities are common in children throughout the world, particularly in Malawi, Africa where the causes are unknown. We have identified that Blount disease and calcium deficiency rickets are the likely causes of these deformities and propose calcium supplementation as a potential treatment of Malawian rickets. Introduction: Surgical correction of rickets-like lower limb deformities is the most common paediatric operation performed at Beit Cure Orthopaedic Hospital, Malawi. The aim of this study was to investigate the aetiology of these deformities. Methods: Children with a tibio-femoral angle of deformity >20° were enrolled (n = 42, 3.0–15.0 years). Anthropometric and early life and well-being data were collected. Early morning serum and urine samples were collected on the morning of the operation for markers of calcium and phosphate homeostasis. Knee radiographs were obtained, and the children were diagnosed with either Blount (BD, n = 22) or evidence of rickets disease (RD, n = 20). As BD is a mechanical rather than metabolic disease, BD were assumed to be biochemically representative of the local population and thus used as a local reference for RD. Results: There were no differences in anthropometry or early life experiences between BD and RD. Parathyroid hormone (PTH), 1,25-dihydroxyvitamin D, total alkaline phosphatase and urinary phosphate were significantly higher and serum phosphate, 25-hydroxyvitamin D (25OHD) and tubular maximal reabsorption of phosphate significantly lower in RD than BD. There was no difference in serum calcium, fibroblast growth factor 23 or markers of iron status between groups. All children had 25OHD > 25 nmol/L. Conclusions: Vitamin D deficiency is not implicated in the aetiology of RD or BD in Malawian children. The cause of RD in Malawi is likely to be dietary calcium deficiency leading to elevated PTH resulting in increased losses of phosphate from the bone and glomerular filtrate. The causes of BD remain unclear; there was no evidence in support of previously suggested risk factors such as being overweight or starting to walk early. Prior to surgical intervention, supplementation with calcium should be considered for children with RD

'In-ger-land, In-ger-land, In-ger-land! : exploring the impact of soccer on the sense of belonging of those seeking asylum in the UK

Utilising research conducted in Sheffield (UK) with people seeking asylum,this article explores the ways in which soccer might be used to create a sense of belonging in the host country. It explores participant feelings about soccer and its potential to alleviate the pressures that the status of being an ‘asylum seeker’ brings. The ways in which soccer may play a role in the identity formation of those seeking asylum is considered in relation to both self-identity and the perceptions of others. The findings of this exploratory study suggest that the various ways of interacting with soccer can provide participants with a sense of control, identity and belonging

Moving out of the shadows: accomplishing bisexual motherhood

Our qualitative study explored the ways in which bisexual mothers came to identify as such and how they structured their relationships and parenting within hetero-patriarchal society. The experiences of seven self-identified White bisexual women (aged from 28 to 56-years-old) from across England and the Republic of Ireland were investigated through semi-structured interviews. Participants’ children were aged 8 months to 28 years old at the time of their interviews. A thematic narrative analysis highlighted the following issues that participants had encountered in constructing their self-identity: prioritizing children; connecting and disconnecting with others and finessing self-definition; questioning societal relationship expectations. Nevertheless, participants varied considerably in how each of the themes identified were reflected in their lives, in particular depending upon each participant’s interpretation of her local social context. Both motherhood and self-identifying as bisexual gave a sense of meaning and purpose to participants’ life stories, although participants sometimes foregrounded their commitment to their children even at a personal cost to their bisexual identity. Using three different theoretical perspectives from feminist theory, queer theory and life course theory, the narratives analysed revealed ways in which bisexual motherhood not only had been influenced both intentionally and unintentionally by heteronormative expectations but also had directly and indirectly challenged these expectations
