AbstractLong-term skills training is known to induce neuroplastic alterations, but it is still debated whether these changes are always modality-specific or can be supramodal components. To address this issue, we compared finger-targeted somatosensory-evoked and auditory-evoked potentials under both Go (response) and Nogo (response inhibition) conditions between 10 baseball players, who require fine hand/digit skills and response inhibition, to 12 matched track and field (T&F) athletes. Electroencephalograms were obtained at nine cortical electrode positions. Go potentials, Nogo potentials, and Go/Nogo reaction time (Go/Nogo RT) were measured during equiprobable somatosensory and auditory Go/Nogo paradigms. Nogo potentials were obtained by subtracting Go trial from Nogo trial responses. Somatosensory Go P100 latency and Go/Nogo RT were significantly shorter in the baseball group than the T&F group, while auditory Go N100 latency and Go/Nogo RT did not differ between groups. Additionally, somatosensory subtracted Nogo N2 latency was significantly shorter in the baseball group than the T&F group. Furthermore, there were significant positive correlations between somatosensory Go/Nogo RT and both Go P100 latency and subtracted Nogo N2 latency, but no significant correlations among auditory responses. We speculate that long-term skills training induce predominantly modality-specific neuroplastic changes that can improve both execution and response inhibition.

Over the years, the field of geotechnical engineering focused on physical, chemical and mechanical aspects of the geomaterials. However, recent developments in environmental geotechnics have highlighted the impact of biological processes on geo-materials and their performance. Also, the present day geotechnical problems favour biological interventions to develop eco-friendly and sustainable technology. In view of this, the present study is a preliminary investigation on the impact of microbial loading on fine-grained soils. In addition, a protocol has been developed to establish ‘bio-geo interface’ between bacteria and the geo-material. However, long term studies are demanded in this direction for in-depth understanding of the mechanism for development of prospective application.

Biased Distribution

The preponderance of studies on salary determination for major league baseball players suggests that significant pay differences do not exist between races. The possibility exists, however, that salary discrimination may be disguised by a racially biased distribution of long-term contracts. This study suggests that nonwhites are not victimized by long-term contract discrimination, which is consistent with the findings of others on pay discrimination in major league baseball.

Cross Border Cooperation

The article illuminates the dynamics of bilateral cross-border cooperation between two vastly different legal-administrative partners. The analysis utilizes empirical findings of a case study on bilateral Finnish–Russian crime prevention cooperation. Currently, both the differences in national legislations and the fast-changing administrative environment make this cooperation challenging. The case study showed that bilateral cooperation, which is the dominant form of cooperation between EU member states and Russia, is currently affected by disjointed and even competing multilateral and bilateral structures, differences in criminal law and procedure, gaps between international treaties and national legislation, local and regional variations of practices, weak institutional trust and abrupt policy changes. The results indicate that the effectiveness of cross-border networks cannot be assessed strictly in terms of quantitative outcomes. Further long-term development of the cooperation requires both realistic understanding of legal-administrative constraints and strong commitment at the national and supranational political levels. Points for practitioners Future long-term development of cross-border crime prevention cooperation between EU member countries and the Russian Federation requires more flexible crime prevention instruments and institutionalization of joint investigation teams. The optimal model in joint criminal investigations with Russian authorities could be one where the evidence of the protocol of the preliminary investigation could be acquired through direct regional connections between authorities. In practice, this requires a much stronger practical trust between different levels of authorities in the EU member countries and the Russian Federation, reconciliation of differences in national legislations and long-term political commitment at the highest level.

Selection Of

In the year 2000, the Japanese geological disposal program for high-level radioactive waste (HLW) moved from the phase of generic research and development into the phase of implementation. Following legislation entitled the “Specified Radioactive Waste Final Disposal Act” (hereafter “the Act”), the Nuclear Waste Management Organization of Japan (NUMO) was established as the implementing organization in October 2000. The assigned activities of NUMO include repository site selection, developing relevant license applications and construction, operation and closure of the repository. To initiate the first stage, NUMO has chosen an “open solicitation” approach for finding candidate sites in the belief that the support of local communities is essential to the success of this highly public, long-term project extending over more than a century. Based on this concept, NUMO announced the start of open solication for volunteer municipalities for selection of Preliminary Investigation Areas to the public on December 19, 2002. This paper describes NUMO’s open solicitation of volunteer municipalities for a potential disposal site.

Geological and ocean sequestration of carbon dioxide is a potential climate change mitigation option that is currently receiving an increasing level of attention within business, academic and policy communities. This paper presents a preliminary investigation of possible public reaction to the technologies under consideration. Using a focus group approach, we consider the similarities between carbon storage technologies and analogous technologies that have generated strong reactions with the public. Initial results suggest that, in principle, carbon capture and storage may be seen as an acceptable approach as a bridging policy while other options are developed. However, concerns were raised regarding the safety of storage and trust in the ability of the various institutions to oversee the process in the long term. This analysis forms part of an on-going study which will continue to investigate the perceptions of a range of stakeholders.

SummaryGenistein and daidzein are isoflavones which are reported to influence the reproductive system in a variety of mammalian species. This pilot study aimed to determine if dietary isoflavones could potentially influence reproductive parameters in domestic cats, when consumed during the postnatal development period. Cats (n = 12) were maintained on either a treatment (150 µg/g DM genistein and 150 µg/g DM daidzein, n = 4) or control (isoflavone free, n = 8) diet from weaning, up to 414 (±17.2) days post-weaning. Vaginal smears were taken thrice weekly and examined for oestrogen-induced cellular degradation in all cats. Behavioural indicators of oestrous were routinely scored for the presence or absence of six key behaviours. Genistein and daidzein did not alter puberty onset or oestrous cycle parameters in these cats (P > 0.05). Behavioural scores were higher in cats in the treatment group than control. Incidence of apparent spontaneous ovulation (inferred from extended inter-oestrous periods) was greater in treated cats than control cats, although serum hormone profiles were not available to confirm this observation. Further testing is warranted.
