This paper describes availability of personal Web-pages and a prototype development for Decision Support for Internet Users, called DSIU, which is an area of research for decision support by using information on the Internet. The availability of Web-pages concerns usage of formal pages, which are provided by companies and so on, and personal pages, which are provided by private persons. Web-pages are gathered by using an Internet search engine to determine destinations for travel and personal pages are confirmed to provide (...) much subjective information than formal pages. The prototype development concerns a travel recommendation system, which is a kind of decision support systems. The prototype uses subjective and objective information on the Internet to select several destinations for users and to provide explanations the reason why the destinations are recommended. This paper also describes our perspective of DSIU researches. (shrink)

KM (Knowledge Management) systems have recently been adopted within the realm of enterprise management. On the other hand, data mining technology is widely acknowledged within Information systems' R&D Divisions. Specially, acquisition of meaningful information from Web usage data has become one of the most exciting eras. In this paper, we employ a Web based KM system and propose a framework for applying Web Usage Mining technology to KM data. As it turns out, task duration varies according to different user operations (...) such as referencing a table-of-contents page, down-loading a target file, and writing to a bulletin board. This in turn makes it possible to easily predict the purpose of the user's task. By taking these observations into account, we segmented access log data manually. These results were compared with results abstained by applying the constant interval method. Next, we obtained a segmentation rule of Web access logs by applying a machine-learning algorithm to manually segmented access logs as training data. Then, the newly obtained segmentation rule was compared with other known methods including the time interval method by evaluating their segmentation results in terms of recall and precision rates and it was shown that our rule attained the best results in both measures. Furthermore, the segmented data were fed to an association rule miner and the obtained association rules were utilized to modify the Web structure. (shrink)

In the long run, changes in society, both local and global, are inevitable. What, then, is and should be the relation between a general theory of law and social change? In the 1995 Kobe Lecture in Japan, Josef Raz said, “By and large, only bad theory can lead to change.” But a ‘good theory’, intended only to describe the normative world and not directly to change it or society, enlightens us in a way that changes our outlook in one way (...) or another. As our picture of the world changes, to that extent the change will be reflected in our practice. The change in practice in turn will affect society bringing about its change in the long run. That change can be either what was intended by the theory or an unintended consequence of it, sometimes favorable and sometimes disastrous. A theory may change the course of things as well by putting a halt to change. But if we can tell in advance that the theory will not lead to any social change whatsoever, it only means that the theory is trivial, or valueless even as a description. (shrink)

This paper investigates the task of reference resolution in the legal domain. This is a new interesting task in Legal Engineering research. The goal is to create a system which can automatically detect references and then extracts their referents. Previous work limits itself to detect and resolve references at the document targets. In this paper, we go a step further in trying to resolve references to sub-document targets. Referents extracted are the smallest fragments of texts in documents, rather than the (...) entire documents that contain the referenced texts. Based on analyzing the characteristics of reference phenomena in legal texts, we propose a four-step framework to deal with the task: mention detection, contextual information extraction, antecedent candidate extraction, and antecedent determination. We also show how machine learning methods can be exploited in each step. The final system achieves 80.06 % in the F1 score for detecting references, 85.61 % accuracy for resolving them, and 67.02 % in the F1 score for the end-to-end setting task on the Japanese National Pension Law corpus.

This article addresses the problem of automatically extracting legal indices which express the important contents of legal documents. Legal indices are not limited to single-word keywords and compound-word keywords, they are also clause keywords. We approach index extraction using structural information of Japanese sentences, i.e. chunks and clauses. Based on the assumption that legal indices are composed of important tokens from the documents, extracting legal indices is treated as a problem of collecting chunks and clauses that contain as many important (...) tokens as possible. Each token is assigned a weight which is a statistical score, e.g. TF–IDF and Okapi BM25, to indicate its importance. The importance of a chunk or clause is determined based on the average weight of tokens included in that chunk or clause. Then, highly weighted chunks and clauses are recognized as the indices for legal documents. The experimental results on Japanese National Pension Act data show that our proposed method achieves better performance than TextRank, the most popular unsupervised method in extracting single-word and compound-word keywords. In addition, this approach is also applicable to extract clause keywords with high performance. (shrink)

This paper proposes several recurrent neural network-based models for recognizing requisite and effectuation parts in Legal Texts. Firstly, we propose a modification of BiLSTM-CRF model that allows the use of external features to improve the performance of deep learning models in case large annotated corpora are not available. However, this model can only recognize RE parts which are not overlapped. Secondly, we propose two approaches for recognizing overlapping RE parts including the cascading approach which uses the sequence of BiLSTM-CRF models (...) and the unified model approach with the multilayer BiLSTM-CRF model and the multilayer BiLSTM-MLP-CRF model. Experimental results on two Japan law RRE datasets demonstrated advantages of our proposed models. For the Japanese National Pension Law dataset, our approaches obtained an \ score of 93.27% and exhibited a significant improvement compared to previous approaches. For the Japan Civil Code RRE dataset which is written in English, our approaches produced an \ score of 78.24% in recognizing RE parts that exhibited a significant improvement over strong baselines. In addition, using external features and in-domain pre-trained word embeddings also improved the performance of RRE systems. (shrink)

Ongoing developments, such as digitalization, increased the interference of the work and nonwork life domains, urging many to continuously manage engagement in respective domains. The COVID-19 pandemic and subsequent home-office regulations further boosted the need for employees to find a good work-nonwork balance, thereby optimizing their health and well-being. Consequently, proactive individual-level crafting strategies for balancing work with other relevant life domains were becoming increasingly important. However, these strategies received insufficient attention in previous research despite their potential relevance for satisfying (...) psychological needs, such as psychological detachment. We addressed this research gap by introducing a new scale measuring crafting for a work-nonwork balance and examining its relevance in job-and life satisfaction, work engagement, subjective vitality, family role and job performance, boundary management and self-rated work-nonwork balance. The Work-Nonwork Balance Crafting Scale was validated in five countries, encompassing data from a heterogeneous sample of more than 4,200 employees. In study 1, exploratory factor analysis revealed a two-factorial scale structure. Confirmatory factor analysis, test for measurement invariance, and convergent validity were provided in study 2. Replication of confirmatory factor analysis, incremental and criterion validity of the Work-Nonwork Balance Crafting Scale for job and life satisfaction were assessed in study 3. Study 4 displayed criterion validity, test–retest reliability, testing measurement invariance, and applicability of the scale across work cultures. Finally, study 5 delivered evidence for the Work-Nonwork Balance Crafting Scale in predicting work-nonwork balance. The novel Work-Nonwork Balance Crafting Scale captured crafting for the challenging balance between work and nonwork and performed well across several different working cultures in increasingly digitalized societies. Both researchers and practitioners may use this tool to assess crafting efforts to balance both life domains and to study relationships with outcomes relevant to employee health and well-being.

Shaping off-job life is becoming increasingly important for workers to increase and maintain their optimal functioning. Proactively shaping the job domain has been extensively studied, but crafting in the off-job domain has received markedly less research attention. Based on the Integrative Needs Model of Crafting, needs-based off-job crafting is defined as workers’ proactive and self-initiated changes in their off-job lives, which target psychological needs satisfaction. Off-job crafting is posited as a possible means for workers to fulfill their needs and enhance (...) well-being and performance over time. We developed a new scale to measure off-job crafting and examined its relationships to optimal functioning in different work contexts in different regions around the world. Furthermore, we examined the criterion, convergent, incremental, discriminant, and structural validity evidence of the Needs-based Off-job Crafting Scale using multiple methods. The results showed that off-job crafting was related to optimal functioning over time, especially in the off-job domain but also in the job domain. Moreover, the novel off-job crafting scale had good convergent and discriminant validity, internal consistency, and test–retest reliability. To conclude, our series of studies in various countries show that off-job crafting can enhance optimal functioning in different life domains and support people in performing their duties sustainably. Therefore, shaping off-job life may be beneficial in an intensified and continually changing and challenging working life. (shrink)

This study aims to provide an integrated perspective on job crafting and its antecedents through the exploration of the joint effects of individual-level and team-level job crafting on employee work engagement. Drawing on conservation of resources (COR) theory, we propose that engaging in job crafting behaviors is promoted by the presence of job-related resources. In turn, job crafting is expected to result in higher levels of work engagement. We expect this reasoning to hold for the individual as well as the (...) team/collective levels. The hypotheses were tested using data from 287 medical professionals from 21 hospital units of a Chinese public hospital. Findings from two-level Bayesian structural equation modeling supported the idea that at the individual level, individual job crafting behaviors partially mediated the relationship from individual resources to individual work engagement. Further, collective crafting mediated the relationship from team resources to individual work engagement. In addition, a positive cross-level relation between collective crafting and individual crafting was found. We conclude that stimulated by resources, both job crafting processes at the individual-level and team-level can promote individual work engagement in Chinese employees. (shrink)

Objectives: This study aimed to conduct a systematic review and meta-analysis of randomized controlled trials (RCTs) to improve subjective well-being (SWB), including evaluative, hedonic, and eudemonic well-being, and the mental component of quality of life (QOL) of working population. Methods: A literature search was conducted, using PubMed, Embase, PsycINFO, and PsycARTICLES. Eligible studies included those that were RCTs of any intervention, conducted among healthy workers, measured SWB as a primary outcome, and original articles in English. Study characteristics, intervention, outcomes, and (...) results on SWB outcomes were extracted by the investigators independently. After a brief narrative summarizing and classifying the contents of the interventions, the included outcomes were categorized into each aspect of SWB (evaluative, hedonic, and eudemonic well-being, and the mental component of QOL). Finally, the characteristics of the effective interventions for increasing each aspect were summarized, and the pooled effect of interventions on SWB was investigated by a meta-analysis. Publication bias was investigated by drawing a funnel plot and conducting Egger's test. Results: From the 5,450 articles found, 39 met the inclusion criteria for the systematic review. The interventions included in this review were classified into six categories (physical activity, ergonomics, psychological, environmental, multicomponent intervention, and others). The meta-analysis from 31 studies showed that the pooled effect of included interventions on SWB was significantly positive (standardized mean difference (SMD) = 0.51; standard error (SE) = 0.10). A funnel plot showed there were extremely large or small SMDs, and Egger's test was significant. Thus, we conducted sensitivity analysis, excluding these extreme SMDs, and confirmed that the estimated pooled effect was also significantly positive. Subgroup analyses for separate types of interventions showed the effects of psychological interventions (e.g., mindfulness, cognitive behavioral based approach, and other psychological interventions) were also significantly positive. Conclusion: The current study revealed the effectiveness of interventions for increasing SWB. Specifically, psychological interventions (e.g., mindfulness, cognitive behavioral based approach, and other psychological interventions) may be useful for improving SWB. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:The Artist as Professional in JapanKazuyo Nakamura and Akio OkazakiThe Artist as Professional in Japan, edited by Melinda Takeuchi. Stanford, Calif.: Stanford University Press, 2004, 262pp., $45.00 cloth.With the increase of cross-cultural academic exchange in our time, more accurate information on art from other cultures has become more easily available, and curriculum development of art education directed toward multiculturalism has been brought to realization. There is need emerging (...) among art educators for academic resources for teaching cross-cultural subject matters, and The Artist as Professional in Japan provides historical information helpful in gaining a critical understanding of the nature of Japanese art discourse. The volume is edited from a fresh sociocultural perspective by Melinda Takeuchi, professor of Japanese art at Stanford University.Takeuchi, noticing that few scholarly books on the profession of Japanese artists are available to students of art history in the United States, set about the volume in concerted efforts with her colleagues. The volume consists of individual case studies on different Japanese artists; they are well-known sculptors, painters, potters, printmakers, and architects and are recognized in Japan as representative in different eras from the seventh to the twentieth century. Running through the individual studies, there is a concern for political forces that shaped art discourse and the identity of the Japanese artist. The following questions are asked: What degree of control did the artists exercise over their métier? What were some of the dynamics operating in the production, consummation, and evaluation of art and artist? How was the image of the artist formed during various periods? Working with these questions, seven case studies address issues of canon formation of art by looking into the terrain of the meaning of a critical word, Shoku-nin; it literally means people (nin) with an occupation (shoku) and denotes the collective artisan class.Different art historians and art theorists take a unique approach for developing each case study in the volume. Donald F. McCallum's study in chapter 2 is on the Buddhist Icons of the Shaka Triad during the Asuka Period (ca.590-ca.650), and it is asked what were the political forces working on the production of the [End Page 118] icons. In contrary to orthodox view, it is argued that the icons were produced not by an individual sculptor named Tori-busshi but by the guilds of which the supervisor was Tori. Also, it is argued that the icons were produced with the patronage of soga clan, the dominant political force of the time, not by the imperial family, including Shotoku Taishi.Karen L. Brock in chapter 3 examines the case of E'nichibo Jonin (active ca.1211-ca.1243), the painter of Saint Myoe. The case shows that the ateliers of temples, such as Kozanji in Kyoto, played a central role in producing and distributing sacred images. This study makes clear that few individual painters, such as those named ebusshi, participated in the formation of the canon of Japanese painting, but collective political forces, such as Kozanji ateliers, exercised power in bringing out sacred objects.In chapter 4 Melinda Takeuchi takes up the case of Tosa Mitsunobu (1434-ca.1523), an artisan painter active in Kyoto court circles. It shows a historical fact particular to Japanese art discourse—that later artists manipulated the names of earlier ones for professional or cultural merits. Taking notice of the fact that Mitsunobu's name late became synonymous with a production unit that shares secret techniques of products, Takeuchi concludes, "In the end, the name of an artist transcends time, space, materiality, and ultimately discourse itself" (101).The study of Louise Allison Cort in chapter 5 is on the case of Morita Kyuemon in the seventeenth century, a warrior trained as a potter and running the Odo pottery in the Tosa domain. By exploring the motivations of the Tosa domain in trying to transform local products into refined and stylish pottery worthy of formal presentation to other domain rulers (daimyo), to government officials, and to the shogun in Edo, this chapter demonstrates how both the potter and the ruler actively sought to join the aesthetic mainstream of their own day.In...
