The entrance exams to Japanese universities have long been criticised for creating negative “washback” on English education in high schools in Japan, as teachers have often focused their teaching efforts on teaching grammar to prepare students for these exams rather than helping students to develop competency in spoken English. Many government initiatives have attempted to reform English language education by encouraging a greater focus on speaking competency. This paper outlines the nature of the Japanese university entrance exam system, considers the phenomenon of washback, and critically reviews the body of empirical research related to washback in the Japanese context. A systematic review was conducted on articles published between 1993 and June, 2022. These articles were subjected to thematic analysis in which four broad categories were identified: learner behaviour; washback to teacher behaviour; affective factors; and washback specifically from the introduction of the listening test. Findings suggest that more empirical studies are required to understand the complex nature of washback from university entrance exams, and that future research is required to examine potential washback from four-skills testing and, in particular, from the inclusion of a speaking test.

Salinity is a major environmental stress that affects agricultural productivity worldwide. One approach to improving salt tolerance in crops is through high expression of the Arabidopsis gene AtNHX1, which encodes a vacuolar sodium/proton antiporter that sequesters excess sodium ion into the large intracellular vacuole. Sequestering cytosolic sodium into the vacuoles of plant cells leads to a low level of sodium in cytosol, which minimizes the sodium toxicity and injury to important enzymes in cytosol. In the meantime, the accumulation of sodium in vacuoles restores the correct osmolarity to the intracellular milieu, which favors water uptake by plant root cells and improves water retention in tissues under soils that are high in salt. To improve the yield and quality of peanut under high salt conditions, AtNHX1 was introduced into peanut plants through Agrobacterium-mediated transformation. The AtNHX1-expressing peanut plants displayed increased tolerance of salt at levels up to 150 mM NaCl. When compared to wild-type plants, AtNHX1-expressing peanut plants suffered less damage, produced more biomass, contained more chlorophyll, and maintained higher photosynthetic rates under salt conditions. These data indicate that AtNHX1 can be used to enhance salt tolerance in peanut.

<P><B>The self‐assembly of CdSe quantum dots (QDs) onto a patterned silica surface</B> generated from surface microcontact click printing is presented. The mechanically robust self‐assembly process produces patterns of QDs which remain steadfast, even as subsequent reactions are performed on the substrate, demonstrating the utility and ease of this self‐assembly process.</P>

The Immunoglobulin $IgG_1$ and $IgG_2$ isotype immune responses of domestic ruminants and mice to Cowdria. ruminantium live infection or by immunization with inactivated organisms were determined by the enzyme linked immunosorbent assay and Western blotting. Immunization of goats with inactivated elementary bodies (IEBs) led to a predominant $IgG_1$ isotype response. This indicated that a Th2 response was induced. After challenge, the IgG isotype responses were mixed whereby both $IgG_1$ and $IgG_2$ antibodies were detected. Two goats that survived virulent challenge had a predominant $IgG_2$ isotype response. In cattle live infection by natur l challenge or experiment led to a predominant $IgG_1$ isotype response. Immunization of cattle with IEBs however led to mixed IgG responses characterized by similar $IgG_1$ and $IgG_2$ ratios. In the mouse live infection led to a predominant $IgG_2$ isotype response. This indicated the mouse developed a true Th1 type cell mediated immune response when inoculated with live organisms. Immunization with inactivated organisms on the other hand led to a dominant $IgG_1$ response. It is evident from this work that the immune responses of ruminants and mice to C. ruminantium are different and that using mice as the experimental model for immune responses to Cowdria ruminantium. is not the appropriate.
