A Study of ESL Students’ Perceptions and Performance in One-on-One and Paired Oral Tests

The aim of this classroom-based research project was to gain insight into student perceptions and performances in two different oral assessment formats: a one-on-one interview with the teacher and a paired interaction with a classmate. The participants were 6 female and 6 male international students enrolled in high-intermediate level ESL courses in the Intensive English Center at a mid-size university. In a within-subject designed format, the students alternated the order in which they participated in the test formats, with two alternating speaking prompts. Data collected via pre-test and post-test questionnaires was analyzed in terms of seven themes of perception: nervousness, preparedness, interest, interaction, effectiveness of format, belief in performance, and preference. The results indicated that students’ attitudes towards the two formats were generally positive and that there was not a significant difference in regard to themes of perception within the two formats. After performing a paired samples t-test with the average group scores from the two assessments, results revealed that the test format did not have a statistically significant effect on performance. However, as evidenced by post-test questionnaire data and student commentary analysis, it can be concluded that the two test formats are not equal interactions and should not be considered equal measurements of oral proficiency. The implication on pedagogy is that teachers should utilize the two test formats for different purposes in their assessment practices

Domestic and Subversive: The Roles of Women in the Children\u27s Novels of Louisa May Alcott

This paper examines the roles of women in Louisa May Alcott’s children’s novels and the ways the author subverts and reinforces society’s expectations of women through her wildly popular writing. It primarily discusses Little Women (1868), An Old-Fashioned Girl (1870), Little Men (1871), Eight Cousins (1875), Rose in Bloom (1876), and Jo’s Boys (1886)

The Carnivore Connection Hypothesis: Revisited

The “Carnivore Connection” hypothesizes that, during human evolution, a scarcity of dietary carbohydrate in diets with low plant : animal subsistence ratios led to insulin resistance providing a survival and reproductive advantage with selection of genes for insulin resistance. The selection pressure was relaxed at the beginning of the Agricultural Revolution when large quantities of cereals first entered human diets. The “Carnivore Connection” explains the high prevalence of intrinsic insulin resistance and type 2 diabetes in populations that transition rapidly from traditional diets with a low-glycemic load, to high-carbohydrate, high-glycemic index diets that characterize modern diets. Selection pressure has been relaxed longest in European populations, explaining a lower prevalence of insulin resistance and type 2 diabetes, despite recent exposure to famine and food scarcity. Increasing obesity and habitual consumption of high-glycemic-load diets worsens insulin resistance and increases the risk of type 2 diabetes in all populations

Sleep and Cognition

Sleep is an ancestral and primitive behaviour, an important part of life thought to be essential for restoration of body and mind. As adults, we spend approximately a third of our lives asleep and as we progress through life there are certain shifts in sleep architecture, most notably in sleep quantity. These biological or physiological age-dependent changes in sleep are well documented [1], and alongside the shifts in sleep architecture there is an increased susceptibility to certain sleep disorders. Sleep disturbances and sleep deprivation are common in modern society. Most studies show that since the beginning of the century, populations have been subjected to a steady constant decline in the number of hours devoted to sleep. This is due to changes in a variety of environmental and social conditions (e.g. less dependence on daylight for most activities, extended shift work and 24/7 round-the-clock activities

Marsupial and monotreme milk : a review of its nutrient and immune properties

All mammals are characterized by the ability of females to produce milk. Marsupial (metatherian) and monotreme (prototherian) young are born in a highly altricial state and rely on their mother’s milk for the first part of their life. Here we review the role and importance of milk in marsupial and monotreme development. Milk is the primary source of sustenance for young marsupials and monotremes and its composition varies at different stages of development. We applied nutritional geometry techniques to a limited number of species with values available to analyze changes in macronutrient composition of milk at different stages. Macronutrient energy composition of marsupial milk varies between species and changes concentration during the course of lactation. As well as nourishment, marsupial and monotreme milk supplies growth and immune factors. Neonates are unable to mount a specific immune response shortly after birth and therefore rely on immunoglobulins, immunological cells and other immunologically important molecules transferred through milk. Milk is also essential to the development of the maternal-young bond and is achieved through feedback systems and odor preferences in eutherian mammals. However, we have much to learn about the role of milk in marsupial and monotreme mother-young bonding. Further research is warranted in gaining a better understanding of the role of milk as a source of nutrition, developmental factors and immunity, in a broader range of marsupial species, and monotremes

Using Specialist Screening Practitioners (SSPs) to increase uptake of the Bowel Scope (Flexible Sigmoidoscopy) Screening Programme: a study protocol for a feasibility single-stage phase II trial

Background: The NHS Bowel Scope Screening (BSS) programme offers men and women aged 55 years a onceonly flexible sigmoidoscopy (FS), a test that can help reduce colorectal cancer (CRC) incidence and mortality. However, the benefits of BSS are contingent on uptake. This National Institute for Health Research-funded singlestage phase II trial will test the feasibility of using patient navigation (PN), an intervention that offers support to patients to overcome barriers to healthcare, to increase BSS uptake within a socially deprived area of England. Methods/design: All individuals invited for BSS at South Tyneside NHS Foundation Trust during the 6-month recruitment period will be invited to take part in the study. Consenting participants will be randomised to receive PN or usual care in a 2:1 ratio. PN involves non-attenders receiving a phone call from a Specialist Screening Practitioner (SSP) who will elicit reasons for non-attendance and offer educational, practical, and emotional support as needed. If requested by the patient, another appointment for BSS will then be arranged. We anticipate 30 % of participants will be non-attenders. Using A’Hern single-stage design, with 20 % significance level and 80 % power, at least 35 participants who receive PN need to subsequently attend for PN to be considered worthy of further investigation in a definitive trial. The primary outcome measure will be the number of participants in the PN group who re-book and attend their BSS appointment. A qualitative analysis of the PN transcripts, and interviews with the SSPs, will also be conducted, alongside a quantitative analysis of completed patient-reported experience questionnaires. An economic analysis will calculate the costs of delivering PN. Discussion: This feasibility study will be instrumental in deciding whether to conduct the first definitive trial of PN in BSS in England. If PN is subsequently shown to be cost-effective at increasing uptake of BSS, NHS policies could be modified to implement PN as a standard service. The results will be disseminated in peer-reviewed journals and at scientific conferences. Trial registration: International Standard Randomised Controlled Trial Number, ISRCTN1331475

The physicochemical investigation of hydrothermally reduced textile waste and application within carbon-based electrodes.

From Europe PMC via Jisc Publications RouterHistory: ppub 2019-04-01, epub 2019-04-10Publication status: PublishedTextile waste is on the rise due to the expanding global population and the fast fashion market. Large volumes of textile waste are increasing the need for new methods for recycling mixed fabric materials. This paper employs a hydrothermal conversion route for a polyester/cotton mix in phosphoric acid to generate carbon materials (hydrochars) for electrochemical applications. A combination of characterization techniques revealed the reaction products were largely comprised of two major components. The first is a granular material with a surface C : O ratio of 2 : 1 interspersed with phosphorous and titanium proved using energy dispersive X-ray spectroscopy, and the other is a crystalline material with a surface C : O ratio of 3 : 2 containing no phosphorous or titanium. The latter material was found via X-ray diffraction and differential scanning calorimetry to be terephthalic acid. Electrochemical experiments conducted using the hydrochar as a carbon paste electrode demonstrates an increase in current response compared to carbon reference materials. The improved current responses, intrinsically related to the surface area of the material, could be beneficial for electrochemical sensor applications, meaning that this route holds promise for the development of a cheap recycled carbon material, using straightforward methods and simple laboratory reagents
