STEM engagement with special needs learners: inception of special needs engineering pedagogy

Declining STEM Education interest is a key challenge to fulfil the technical job market demand to drive the future economic growth. Interestingly, various institutions comprising Universities, Technical corporations, NGOs, Govt organization, etc. have been practicing STEM education promotion at primary and secondary levels. However, engagement with students from Special Needs Learners (SNL) is less covered leading to a very different social challenge involving EDI (Equality, Diversity, and Inclusion). The aim of this study is to understand possibility of implementing engineering pedagogy for special needs learner. The research was carried out through a STEM workshop in the department of mechanical engineering involving students with additional support needs in S3 (14-15 years old) from deprived area. In this workshop, students were introduced to different materials, how materials can be used to increase human quality of life, how engineers test materials and how materials can be used to achieve a sustainable environment and economy through both conventional and active learning pedagogy which included undergraduate level engineering laboratory course involving optical microscopy of microstructures for engineering materials. Results showed that 90% of the learners agreed that after the workshop they had learnt something new about materials and their effect on the environment. Interestingly, it is also revealed that active learning pedagogy is more effective for Special Needs Learners (SNL) compare to conventional theory-based pedagogy. Using an auto-ethnography approach it can be concluded that students enjoyed the workshop and the opportunity to visit the university and the laboratory facilities. They highly engaged throughout the workshop. It is expected that this finding paves the way towards developing Special Needs Engineering Pedagogy in higher education and such innovative pedagogy could be extended to special needs learners in other disciplines such as language learner among SNL community

Diabetes and Technology for Increased Activity (DaTA) Study: Results of a remote monitoring intervention for prevention of metabolic syndrome

Objective: An increasingly aged, overweight, and sedentary population has resulted in elevated risk of cardiovascular disease (CVD). The escalating incidence of diabetes and other chronic illnesses, deficits in health care budgets, and physician shortages, especially in rural communities, have prompted investigations of feasible solutions. The Diabetes and Technology for Increased Activity (DaTA) study was designed to test the effectiveness of a lifestyle intervention driven by self-monitoring of blood glucose (BG), blood pressure (BP), physical activity (PA), and weight to positively impact CVD risk factors in a medically underserviced rural population with a high incidence of metabolic syndrome (MS). Research Design and Methods: Conducted in a community-based research setting, this single-center open feasibility study used smart phones to transmit BP, BG, pedometer, weight, heart rate, and activity measurements to a database. Technology allowed participants to interface with the clinical team and self-monitor their personal health indicators. Results: Twenty-four participants aged 30 to 71 years completed the 8-week intervention. Participants had significant improvement in clinic (p = .046) and self-monitored diastolic BP (p = .001), body mass index (p = .002), and total cholesterol (p = .009), and steps per day. Daily PA increased as well as participants\u27 interest in and willingness to make lifestyle changes that impact health outcomes. Conclusions: The DaTA study demonstrated that self-monitoring of the risk factors for MS and increased PA improved the participant\u27s CVD risk profile. Considering the 8-week time period of this intervention, results are encouraging. This lifestyle intervention, which uses education and technology as tools, confirms the utility of remote health monitoring. © Diabetes Technology Society

Enantioselective simultaneous analysis of selected pharmaceuticals in environmental samples by ultrahigh performance supercritical fluid based chromatography tandem mass spectrometry

In order to assess the true impact of each single enantiomer of pharmacologically active compounds (PACs) in the environment, highly efficient, fast and sensitive analytical methods are needed. For the first time this paper focuses on the use of ultrahigh performance supercritical fluid based chromatography coupled to a triple quadrupole mass spectrometer to develop multi-residue enantioselective methods for chiral PACs in environmental matrices. This technique exploits the advantages of supercritical fluid chromatography, ultrahigh performance liquid chromatography and mass spectrometry. Two coated modified 2.5\ua0μm-polysaccharide-based chiral stationary phases were investigated: an amylose tris-3,5-dimethylphenylcarbamate column and a cellulose tris-3-chloro-4-methylphenylcarbamate column. The effect of different chromatographic variables on chiral recognition is highlighted. This novel approach resulted in the baseline resolution of 13 enantiomers PACs (aminorex, carprofen, chloramphenicol, 3-N-dechloroethylifosfamide, flurbiprofen, 2-hydroxyibuprofen, ifosfamide, imazalil, naproxen, ofloxacin, omeprazole, praziquantel and tetramisole) and partial resolution of 2 enantiomers PACs (ibuprofen and indoprofen) under fast-gradient conditions

Children and older adults exhibit distinct sub-optimal cost-benefit functions when preparing to move their eyes and hands

The provision of advance information allows response priming but heightened responses can cause errors (responding too early or reacting to the wrong stimulus). Thus, a balance is required between the online cognitive mechanisms (inhibitory and anticipatory) used to prepare and execute a motor response at the appropriate time. We investigated the use of advance information in 71 participants across four different age groups: (i) children, (ii) young adults, (iii) middle-aged adults, and (iv) older adults. We implemented 'cued' and 'non-cued' conditions to assess age-related changes in saccadic and touch responses to targets in three movement conditions: (a) Eyes only; (b) Hands only; (c) Eyes and Hand. Children made less saccade errors compared to young adults, but they also exhibited longer response times in cued versus non-cued conditions. In contrast, older adults showed faster responses in cued conditions but exhibited more errors. The results indicate that young adults (18 -25 years) achieve an optimal balance between anticipation and execution. In contrast, children show benefits (few errors) and costs (slow responses) of good inhibition when preparing a motor response based on advance information; whilst older adults show the benefits and costs associated with a prospective response strategy (i.e., good anticipation)

Leptin deficiency-induced obesity affects the density of mast cells in abdominal fat depots and lymph nodes in mice

<p>Abstract</p> <p>Background</p> <p>Mast cells are implicated in the pathogenesis of obesity and insulin resistance. Here, we explored the effects of leptin deficiency-induced obesity on the density of mast cells in metabolic (abdominal fat depots, skeletal muscle, and liver) and lymphatic (abdominal lymph nodes, spleen, and thymus) organs. Fourteen-week-old male leptin-deficient <it>ob/ob </it>mice and their controls fed a standard chow were studied. Tissue sections were stained with toluidine blue to determine the density of mast cells. CD117/c-kit protein expression analysis was also carried out. Furthermore, mast cells containing immunoreactive tumor necrosis factor-α (TNF-α), a proinflammatory cytokine involved in obesity-linked insulin resistance, were identified by immunostaining.</p> <p>Results</p> <p><it>ob/ob </it>mice demonstrated adiposity and insulin resistance. In abdominal fat depots, mast cells were distributed differentially. While most prevalent in subcutaneous fat in controls, mast cells were most abundant in epididymal fat in <it>ob/ob </it>mice. Leptin deficiency-induced obesity was accompanied by a 20-fold increase in the density of mast cells in epididymal fat, but a 13-fold decrease in subcutaneous fat. This finding was confirmed by CD117/c-kit protein expression analysis. Furthermore, we found that a subset of mast cells in epididymal and subcutaneous fat were immunoreactive for TNF-α. The proportion of mast cells immunoreactive for TNF-α was higher in epididymal than in subcutaneous fat in both <it>ob/ob </it>and control mice. Mast cells were also distributed differentially in retroperitoneal, mesenteric, and inguinal lymph nodes. In both <it>ob/ob </it>mice and lean controls, mast cells were more prevalent in retroperitoneal than in mesenteric and inguinal lymph nodes. Leptin deficiency-induced obesity was accompanied by increased mast cell density in all lymph node stations examined. No significant difference in the density of mast cells in skeletal muscle, liver, spleen, and thymus was noted between <it>ob/ob </it>and control mice.</p> <p>Conclusions</p> <p>This study demonstrates that leptin deficiency-induced obesity is accompanied by alterations in the density of mast cells in abdominal fat depots. The divergent distribution of mast cells in subcutaneous versus visceral fat might partially account for their differential biological behavior. Mast cells might also play a role in adaptive immune response occurring in regional lymph nodes in obesity.</p
