Today, science is passing through an era of transformation, where the inundation of data, dubbed data deluge is influencing the decision making process. The science is driven by the data and is being termed as data science. In this internet age, the volume of the data has grown up to petabytes, and this large, complex, structured or unstructured, and heterogeneous data in the form of “Big Data” has gained significant attention. The rapid pace of data growth through various disparate sources, especially social media such as Facebook, has seriously challenged the data analytic capabilities of traditional relational databases. The velocity of the expansion of the amount of data gives rise to a complete paradigm shift in how new age data is processed. Confidence in the data engineering of the existing data processing systems is gradually fading whereas the capabilities of the new techniques for capturing, storing, visualizing, and analyzing data are evolving. In this review paper, we discuss some of the modern Big Data models that are leading contributors in the NoSQL era and claim to address Big Data challenges in reliable and efficient ways. Also, we take the potential of Big Data into consideration and try to reshape the original operationaloriented definition of “Big Science” (Furner, 2003) into a new data-driven definition and rephrase it as “The science that deals with Big Data is Big Science.”

This is a preparatory report of the study on the cognitive characteristics of color names in the congenitally blind. We conducted following two surveys on fifteen congenital blind persons to measure resemblance among color terms in the congenitally blind: (1) Ten participants were asked to recall color names similar to displayed color names which was also(originally)recalled by the participants. (2) Participants judged the similarities of all pairs of color names corresponding to 16 color names; siro, kuro, aka, ki, midori, ao, tya, murasaki, orange, pink, hai, kon, hada, mizu, sora, kimidori. For each of these names selected from recalled color vocabulary survey. The results show that the characteristics of congenital blind persons' color representations were absence of hue ordering seen in sighted people. Instead of hue ordering, multiple hue groups containing perceptually close color terms were identified; dark, light, warm, cool. This grouping could be explained through categorization process in Kay & McDaniel's modified basic term theory.

Objectives: The purpose of this review is to summarize the current evidence on the economic impact of corporate wellness programs (CWPs) in Europe from the results of randomized controlled trials (RCTs) published up to 2013. Methods: A review was undertaken by searching for RCTs with key words in the following databases: PubMed, SPORTDiscus, and Business Source Premier. Only RCTs that evaluated the economic impact of CWPs, and included analyses performed in Europe with results converted into monetary values, were eligible for inclusion. An approach to economic analyses from both an employer’s perspective and a societal perspective was also undertaken. Results: Eleven RCTs were identified, and review of these studies determined that the economic impact of the majority of CWPs analyzed was mostly negative. We discuss a possible explanation for these discrepancies with regard to prior reviews in this area. Despite the fact that the RCT is the “gold standard” for investigating without bias, several limitations to the methodology may have influenced the results of the studies in this review and suggested the use of caution in the interpretation of the results. Conclusions: The findings of this review could be a “wake up call” for companies regarding the high probability of bias from non-RCT studies, the majority of which report a positive economic impact of these programs, and the risk of taking inappropriate decisions based on the results of such studies.

Functions of the hippocampus is dependent on brain-derived-neurosteroids. Because estrogen is synthesized locally in the hippocampus, as well as supplied from the ovary, its functions are attracting much attention. Hippocampal sex-steroids modulate memory-related synaptic plasticity not only slowly but also rapidly. Slow actions of estradiol (E2) occur via nuclear receptors (ERα), while rapid E2 actions occur via synapse-localized ERα. Elevation or decrease of the E2 concentration changes rapidly the density and morphology of spines. Kinase networks are involved downstream of ERα. The long-term depression is modulated rapidly by changes of E2 level. The E2 level is much higher than that in blood circulation. Hippocampus-derived sex-steroids play a major role in modulation of synaptic plasticity.

Background:Few data on the relative efficacy and safety of new P2Y12inhibitors such as prasugrel and ticagrelor in Japanese, Taiwanese and South Korean patients with acute coronary syndromes (ACS) exist.Methods and Results:The multicenter, double-blind, randomized PHILO trial compared the safety and efficacy of ticagrelor vs. clopidogrel in 801 patients with ACS (Japanese, n=721; Taiwanese, n=35; South Korean, n=44; unknown ethnicity, n=1). All were planned to undergo percutaneous coronary intervention and randomized within 24 h of symptom onset. Primary safety and efficacy endpoints were time to first occurrence of any major bleeding event and to any event from the composite of myocardial infarction, stroke or death from vascular causes, respectively.At 12 months, overall major bleeding occurred in 10.3% of ticagrelor-treated patients and in 6.8% of clopidogrel-treated patients (hazard ratio (HR), 1.54; 95% confidence interval (CI): 0.94–2.53); the composite primary efficacy endpoint occurred in 9.0% and in 6.3% of ticagrelor- and clopidogrel-treated patients, respectively (HR, 1.47; 95% CI: 0.88–2.44). For both analyses, the difference between groups was not statistically significant.Conclusions:In ACS patients from Japan, Taiwan and South Korea, event rates of primary safety and efficacy endpoints were higher, albeit not significantly, in ticagrelor-treated patients compared with clopidogrel-treated patients. This observation could be explained by the small sample size, imbalance in clinical characteristics and low number of events in the PHILO population.

静止立位姿勢の神経制御メカニズムの本質的特徴は,姿勢の柔軟性と安定性が同時にかつロバストに実現されている点にあると考えられる.従来の生体運動制御理論の立場では,姿勢あるいは運動の柔軟性と安定性は互いに相反する性質であり,高い安定性を求めると姿勢や運動の柔軟性は低下する.近年,我々は,柔軟性を保ちながらも立位姿勢をロバストに安定化することができる神経制御メカニズムとして,静止立位姿勢の間欠制御モデル(intermittent control hypothesis)を提唱している.本稿では,これまで定説であった立位姿勢のスティッフネス制御と新しい仮説である間欠制御に関して考察する.

Recently, electromagnetic phenomena associated with earthquakes have gotten a lot of attention. So, we have been observed VHF band propagation for long timeand analyzed statistical relation between anomalous line-of-sight propagation in the VHF band and occurrences of earthquakes using quantitative evaluation. Now, we need to detect the anomalous propagation from received data. Therefore, we used a statistical analysis to judge anomalous propagation in a previous study. In this paper, we judged the anomalous propagation by continuous wavelet transform and evaluated the relationship with earthquakes. Furthermore, we introduced hit rate and alarm rate to simplify the relationship between anomalous propagation and earthquakes. As a result, relation between anomalous propagation and earthquakes became clear.

In recent years, a large amount of photovoltaic (PV) generations have been installed in power systems. However, the power output from the PVs is random and intermittent in nature. Therefore, the PV generations pose many challenges to the power system operation. To estimate the impact of these issues on the power system operation, we propose optimal weekly demand and supply simulation method considering a large penetration of photovoltaic generations. In this paper, a study for operation scheduling method considering optimal hot reserve capacity is presented. The effectiveness of the proposed method is shown by using Monte Carlo simulation.

To support the automatic semantic analysis of texts in the humanities, it is not sufficient to analyze words and evaluate word pairs, because it is necessary to process larger units, such as phrases, sentences, and paragraphs. This study proposes the introduction of intratextuality into a digital archive system. In the future, this method will be developed as the basis for semantic analysis of larger units. Classical literary structures that are used frequently in the Old and New Testaments were digitized as a case study. A literary structure data format for a relational database was also implemented. The literary structures of 39 books in the Old Testament and 27 books in the New Testament were digitized. The total number of digitized literary structures was 1,507 and the elements of these structures comprised 7,715 pairs. These data were stored in a Java-based relational database system and a web-based viewer program for rhetorical structures was implemented as a JSP servlet. This web-based program will be combined with an existing digital archive system that can manage intertextuality data. The Java-based relational database system and the JSP servlet will facilitate numerical analyses of the intertextuality and intratextuality of digital archive systems of classical texts, thus making it much easier to conduct scientific analyses of the meanings of texts.

The UC CEISMIC Canterbury Earthquakes Digital Archive was established in response to the devastating earthquakes that struck Canterbury region in New Zealand from September 2010 onwards, including 4 quakes of magnitude 6 or greater and over 11,000 aftershocks. 185 people died and significant parts of Christchurch city were either destroyed or have needed to be demolished, resulting in financial losses of an estimated NZ$30 billion. The rebuild is expected to take 10 – 15 years, and the UC CEISMIC archive is designed to accommodate this, acting as a distributed national (and eventually international) repository for digital content produced as a result of the earthquakes. This paper outlines the design principles and architecture of the archive, describing the commitment to open access and open source that allowed the project team to bring together a broad-ranging national consortium comprised of leading cultural organizations, who work alongside content providers ranging from individual citizens, government agencies and community groups, to large media companies. Principles common to the digital humanities community were used to bond the broader project team, in an interesting example of scholar-led community engagement. The goal is to provide a model that can be used, either in whole or in part, by future teams in need of similar capability.

Although past research has pointed out the importance of the relationship between organizational commitment and organizational learning, there is little consensus regarding how they are influenced by one another. In the present research, we attempted (1) to differentiate two components of organizational learning (i.e., single-loop and double-loop learning) and (2) to figure out the effect of organizational commitment, especially “organizational identification” (one of the two sub-factors of the affective commitment) on each of the two components. We conducted an empirical study using mail survey data randomly sampled in Tokyo. As we predicted, organizational learning behaviors consisted of two discriminating components. We also found that organizational identification had a positive effect on single-loop learning but no significant effect on double-loop learning. Furthermore, emotional attachment to the organization (the other sub-factor of the affective commitment) had no significant effect on organizational learning. The result suggests that organizational identification plays an important role to promote organizational learning, whereas emotional attachment does not.

Fumonisin, a mycotoxin produced by some members of Fusarium fujikuroi species complex, causes swine pulmonary edema and equine leukoencephalomalacia. Clustering of the genes involving fumonisin biosynthesis in the genome have been revealed. The FUM cluster poses many questions in regard to the process obtained by Fusarium and its evolution. In this mini review, fumonisin characteristics are described and the role of fumonisin for the producing fungi and the evolution of the FUM cluster were discussed.
