This study examined the relationship between components of Eccles' (Eccles et al., 1983) expectancy-value model and perceptions of physical competence of children with and without learning disabilities (LD) across three physical activity contexts (physical education class, outdoor school recess, and at home). Participants, 60 children with and without LD between 10 and 13 years, completed the Modified Pictorial Scale of Perceived Physical Competence (Ulrich & Collier, 1990) and an expectancy-value questionnaire measuring perceived importance, usefulness, enjoyment, and gender orientation of selected motor skills. Gender differences in perceptions of physical competence were found in recess and home settings. No significant group differences were observed in perceptions of physical competence. Expectancy-value subscales contributed differently to understanding competence judgments of boys and girls across context. Results are discussed with implications for improving self-concept and expectancy-value among girls toward sport and physical activity.

Introduction: Access to essential medicines is limited in developing countries mainly due to inefficiencies in health supply chain management, such as the absence of standard monitoring frameworks and poorly designed Logistics Management Information Systems (LMIS). Health supply chain managers need accurate and timely data for decision-making. However, routine health information systems suffer from poor data quality, reliance on paper-based reports, insufficient logistic formats, inadequate infrastructure, and limited human resources.

Attending and participating in scientific research meetings and conferences is a key mechanism for researchers to share information and knowledge, build networks, and establish relationships and collaborations to support career development. In the UK, researchers from minoritised or underrepresented groups, may have a different experience at a conference than their peers. As a high profile provider of genomics-focussed life science conferences, Wellcome Connecting Science is committed to ensuring that our events are as inclusive as possible.

Background And Purpose: In proton therapy, a relative biological effectiveness (RBE) of 1.1 is used to convert proton dose into an equivalent photon dose. However, RBE varies with tissue type, fraction dose, and beam quality parameters beyond dose such as linear energy transfer (LET) raising concerns about increased local effectiveness and potential toxicity.

Compelling evidence has demonstrated that rehabilitation through physical exercise, a non-invasive and non-surgical intervention, enhances muscle reinnervation and motor recovery after peripheral nerve injury (PNI) by increasing muscle-derived brain-derived neurotrophic factor (BDNF) expression and triggering TrkB-dependent axonal plasticity. Adenosine has been widely acknowledged to trigger TrkB via A2A receptor (A2AR). Since motor nerve terminals co-express TrkBs and A2ARs and depolarizing conditions increase muscle release of BDNF and adenosine, we examined whether A2ARs activation could recapitulate the functional recovery benefits of intermittent exercise after a nerve crush.

This study focuses on the influence of the partial substitution of cement by Cameroonian corn stover ash (CCSA) on the physical and mechanical behavior of concrete. For this, as materials used, one has first the corn stovers coming from the Bandjoun town in the Koung-khi division, in the West region of Cameroon, which are used to obtain the ashes, while the sand used, came from the Sanaga River in the coastal region of Cameroon. In order to obtain the CCSA, the corn stover is calcined in an oven at 600 °C for 6 h and then characterized; the characterization included infrared spectrometry, X-ray fluorescence spectrometry, fineness of grinding, and absolute density.
