Positive Models in Literature for the At-Risk Student

It has been found that most at-risk students have a very low self-esteem, which contributes to the sense of failure these students feel about their academic life. This study explored the use of bibliotherapy with secondary students in an effort to raise their self-esteem to a level which would counteract the frustration these students feel as they continually find themselves in failing situations in school. Extensive review of available literature on the topics of self-esteem, motivation, at-risk students, and bibliotherapy resulted in the compilation of an annotated bibliography, complete with suggested uses for the works found therein, selected for the secondary student, with the understanding that at-risk students often function academically below grade level

Polymorphisms in the CTLA4 promoter sequence are associated with canine hypoadrenocorticism

Canine hypoadrenocorticism is an immune-mediated endocrinopathy that shares both clinical and pathophysiological similarities with Addison’s disease in humans. Several dog breeds are overrepresented in the disease population, suggesting that a genetic component is involved, although this is likely to be polygenic. Previous research has implicated CTLA4 as a potential susceptibility gene. CTLA4 is an important regulator of T cell function and polymorphisms/mutations in CTLA4 have been associated with a number of autoimmune phenotypes in both humans and rodent models of autoimmunity. The aim of the current study was to undertake a case:control association study of CTLA4 promotor polymorphisms in three dog breeds, cocker spaniels, springer spaniels and West Highland white terriers (WHWT)

Rallying to the Flag - A Consolidated Picture of Armed Forces Children’s Education in Scotland in 2021: Laying Foundations & Promoting Development

This report provides an overview of the numbers of armed forces children at national and local authority level, together with a review of how some authorities have responded to the needs of this part of the pupil population. It therefore marks a start point in explaining how Scotland as a whole and individual Councils are meeting the expectations of the Covenant and the associated responsibilities envisaged by statute. The rationale for this report is that over the years, much has been learned about the nature of the armed forces children’s population in Scotland. The time is now right to bring that information together to identify where there are gaps in our knowledge, to create questions and to make recommendations to guide the next stages of development

Kinetics of the Xanthophyll Cycle and its Role in the Photoprotective Memory and Response

Efficiently balancing photochemistry and photoprotection is crucial for survival and productivity of photosynthetic organisms in the rapidly fluctuating light levels found in natural environments. The ability to respond quickly to sudden changes in light level is clearly advantageous. In the alga Nannochloropsis oceanica we observed an ability to respond rapidly to sudden increases in light level which occur soon after a previous high-light exposure. This ability implies a kind of memory. In this work, we explore the xanthophyll cycle in N. oceanica as a photoprotective memory system. By combining snapshot fluorescence lifetime measurements with a biochemistry-based quantitative model we show that both short-term and medium-term "memory" arises from the xanthophyll cycle. In addition, the model enables us to characterize the relative quenching abilities of the three xanthophyll cycle components. Given the ubiquity of the xanthophyll cycle in photosynthetic organisms the model described here will be of utility in improving our understanding of vascular plant photoprotection with important implications for crop productivity

Hippocampus japapigu, a new species of pygmy seahorse from Japan, with a redescription of H. pontohi (Teleostei, Syngnathidae)

The pygmy seahorse Hippocampus japapigu sp. n. is described based on three specimens, 13.9–16.3 mm SL, collected from a mixed soft coral and algae reef at 11 m depth at Hachijo-jima Island, Izu Islands, Japan. The new taxon shares morphological synapomorphies with the previously described central Indo-Pacific pygmy seahorses, H. colemani, H. pontohi, H. satomiae, and H. waleananus, including extremely small size, 12 trunk rings, strongly raised continuous cleithral ring, snout spine, large spine on the eighth lateral and fifth and 12 superior trunk ridges, respectively, and unusual wing-like-protrusions immediately posterior to the head. Hippocampus japapigu sp. n. can be distinguished from all congeners by the following combination of features in the anterodorsal area of the trunk: bilaterally paired wing-like protrusions formed by a single pair of large, truncate spines projecting dorsolaterad on the first superior trunk ridge, followed by a unique elevated dorsal ridge formed by triangular bony mounds dorsally on the second to fourth superior trunk ridges. In contrast, H. pontohi possesses a pair of large truncate spines projecting strongly laterad on both the first and second superior trunk ridges followed by flat surfaces dorsally on the third and fourth superior trunk rings. The new species can be further differentiated by genetic divergence from H. pontohi (an uncorrected p-distance of 10.1% in the mitochondrial COI gene) and a striking reticulated white and brown lattice pattern on the head, trunk, and tail. Hippocampus japapigu sp. n. represents the fifth species of pygmy seahorse recorded in Japan

Economies of space and the school geography curriculum

This paper is about the images of economic space that are found in school curricula. It suggests the importance for educators of evaluating these representations in terms of the messages they contain about how social processes operate. The paper uses school geography texts in Britain since the 1970s to illustrate the different ways in which economic space has been represented to students, before exploring some alternative resources that could be used to provide a wider range of representations of economic space. The paper highlights the continued importance of understanding the politics of school knowledge
