社会科学研究所の機関リポジトリ : 日本貿易振興機構アジア経済研究所機関リポジトリ（ARRIDE）

The mission of the Institute of Developing Economies, Japan External Trade Organization (IDE-JETRO) is to make intellectual contributions to the world. In 2006 IDE officially launched its Institutional Repository, ARRIDE based on DSpace to accomplish the mission more effectively. ARRIDE was designed as a three server structure; external server, internal server and development server. Since IDE has copyright on the articles produced by its research staff through their research activities, it can deposit these articles without asking authors for permission, which guarantees sustainability of the Repository. In order that contents in ARRIDE are accessed worldwide IDE has been providing various search engines with proper metadata. Among them, RePEc that is a decentralized database on social sciences is very important.

Aiming at improving access to research output through the institutional repository

The paper is to introduce the institutional repository (IR) as a powerful tool to support the researchers of the institution to archive and disseminate their research findings freely to the scholarly community on the Internet. The IR can improve the access to an institution’s research output enormously. The operations of an IR also require various interactions with researchers, which enables the library to gain a solid understanding of research needs and expectations. Through such interaction, the relationship and mutual trust between researchers and the library are strengthened. The experiences of the Institute of Developing Economies (IDE) library can be useful to other special libraries.

In vitro antioxidant and immunomodulatory activity of transglutaminase-treated sodium caseinate hydrolysates

Sodium caseinate (NaCN) was incubated prior to and after hydrolysis with a microbial transglutaminase (TGase) and hydrolysed with Prolyve 1000. The resultant hydrolysates were tested for their immunomodulatory and antioxidant activity. TGase-treated hydrolysates significantly reduced (p < 0.05) the production of IL-6 at 0.5 and 1 mg mL−1 and the non-TGase treated hydrolysate reduced the production of IL-6 at 1 mg mL−1 in concanavalin (ConA) stimulated Jurkat T cells. None of the samples had an effect on IL-2. The hydrolysates showed higher oxygen radical absorbance capacity assay and ferric reducing antioxidant power activity than unhydrolysed NaCN, but no significant (p > 0.05) differences were found between the TGase-treated and non-TGase-treated samples. In the presence of hydrogen peroxide, the non-TGase-treated sample exhibited the highest DNA protective effect in U937 cells. These findings suggest that NaCN derived hydrolysates with and without treatment with TGase may exert specific antioxidant, genoprotective and anti-inflammatory effects.

Foraminifer, epifauna and infauna abundance of ODP Hole 183-1138A and core ELT54.007-PC, Kerguelen Plateau

Late Campanian and Maastrichtian benthic foraminifers are recorded from 12 samples from Ocean Drilling Program (ODP) Leg 183, Cores 183-1138A-52R through 63R (487.3-602.4 meters below seafloor), Kerguelen Plateau, Indian Ocean, and Danian benthics from one sample in the same section. The entire late Maastrichtian foraminifer fauna is noted from a dredge sample 220 km to the north. The structure of the fauna is compared with the Cenomanian-Turonian of the nearby Eltanin core E54-7. Faunas are reviewed in terms of planktonic percentage, composition, epifaunal/infaunal ratios, and dominance/diversity indices. The region was in the cool Austral Faunal Province through the Campanian-Maastrichtian and was probably warmer in the Cenomanian-Turonian. The ODP section is now 1600 meters below sea level and has subsided several hundred meters since deposition. Its fauna is dominated by epifaunal species suggesting little influence of upwelling. The dredge location has subsided little. Its fauna has a high infaunal content consistent with significant influence of upwelling near the plateau edge. The dominant benthic species remain constant through the ODP Cretaceous section, but subdominance changes, and the section is divided into three informal zones based on dominance/subdominance characteristics of the benthic fauna. Brief taxonomic comments are made on several species and some are figured.

Distribution of living benthic foraminifera in sediment cores of cruise M77 Leg 1 and 2, 63-2000 µm fraction

Recent benthic foraminifera and their distribution in surface sediments were studied on a transect through the Peruvian oxygen minimum zone (OMZ) between 10 and 12°S. The OMZ with its steep gradients of oxygen concentrations allows to determine the oxygen-dependent changes of species compositions in a relatively small area. Our results from sediments of thirteen multicorer stations from 79 to 823 m water depth demonstrate that calcareous species, especially bolivinids dominate the assemblages throughout the OMZ. The depth distribution of several species matches distinct ranges of bottom water oxygen levels. The distribution pattern inferred a proxy which allows to estimate dissolved oxygen concentrations for reconstructing oxygen levels in the geological past.

Design and implementation of time efficient trajectories for an underwater vehicle

This paper discusses control strategies adapted for practical implementation and efficient motion of underwater vehicles. These trajectories are piecewise constant thrust arcs with few actuator switchings. We provide the numerical algorithm which computes the time efficient trajectories parameterized by the switching times. We discuss both the theoretical analysis and experimental implementation results.

Assessment reform and educational change in Australia

This chapter addresses the changing climate of assessment policy and practice in Australia in response to global trends in education and the mounting accountability demands of standards-driven reform. Queensland, a State of Australia, has a tradition of respecting and trusting teacher judgment through the practice of, and policy commitment to, externally moderated school-based assessment. This chapter outlines the global trends in curriculum and assessment reform, and then analyzes the impact of international comparisons on national policy. The creation of the Australian Curriculum, Assessment and Reporting Authority (ACARA) together with the intent of establishing a standards-referenced framework raises tensions and challenges for teachers’ practice. The argument for sustaining confidence in teacher-based assessment is developed with reference to research evidence pertaining to the use of more authentic assessments and moderation practices for the purposes of improving learning, equity and accountability. Evidence is drawn from local studies of teacher judgment practice and used to demonstrate these developments and in so doing illuminate the complex issues of engaging the demands of policy while sustaining confidence in teacher assessment.

Randomised controlled trial of an automated, interactive telephone intervention (TLC Diabetes) to improve type 2 diabetes management : Baseline findings and six-month outcomes

Background: Effective self-management of diabetes is essential for the reduction of diabetes-related complications, as global rates of diabetes escalate. Methods: Randomised controlled trial. Adults with type 2 diabetes (n = 120), with HbA1c greater than or equal to 7.5 %, were randomly allocated (4 × 4 block randomised block design) to receive an automated, interactive telephone-delivered management intervention or usual routine care. Baseline sociodemographic, behavioural and medical history data were collected by self-administered questionnaires and biological data were obtained during hospital appointments. Health-related quality of life (HRQL) was measured using the SF-36. Results: The mean age of participants was 57.4 (SD 8.3), 63 % of whom were male. There were no differences in demographic, socioeconomic and behavioural variables between the study arms at baseline. Over the six-month period from baseline, participants receiving the Australian TLC (Telephone-Linked Care) Diabetes program showed a 0.8 % decrease in geometric mean HbA1c from 8.7 % to 7.9 %, compared with a 0.2 % HbA1c reduction (8.9 % to 8.7 %) in the usual care arm (p = 0.002). There was also a significant improvement in mental HRQL, with a mean increase of 1.9 in the intervention arm, while the usual care arm decreased by 0.8 (p = 0.007). No significant improvements in physical HRQL were observed. Conclusions: These analyses indicate the efficacy of the Australian TLC Diabetes program with clinically significant post-intervention improvements in both glycaemic control and mental HRQL. These observed improvements, if supported and maintained by an ongoing program such as this, could significantly reduce diabetes-related complications in the longer term. Given the accessibility and feasibility of this kind of program, it has strong potential for providing effective, ongoing support to many individuals with diabetes in the future.
