The Keiretsu Fable - Where does the Truth Lie?

The success of the Japanese automobile industry has mystified Western scholars for many decades. In the early post-war years, the industry did not receive any blessings from the Bank of Japan. Even MITI was a little pessimistic about the industry’s future. The inclusion of the automobile components industry as part of MITI’s “pick-the-winner” industrial policy appeared almost as an afterthought. Yet against all odds the industry flourished to become one of Japan’s best known success stories. Western scholars and business strategists alike are naturally keen to deconstruct this mystery, while Japanese scholars were no less enthusiastic in documenting and offering an explanation. Many explored the keiretsu structure (networking or supplier relationship) as a possible source of the industry’s competitive advantage. Something has gone amiss however, in this parallel effort, and gaps and misperceptions developed. This paper explores some of the myths surrounding this industry. In the process, it revaluates MITI’s policy and raised another research question of whether some of Toyota’s domestic competitors might have misinterpreted the nature of Toyota’s keiretsu.keiretsu; industrial policy; exclusiveness; MITI

Frequency of Marijuana use by California University Students Based on Gender and Ethnicity: A Quantitative Analysis

The purpose of this quantitative causal-comparative study was to determine the frequency of marijuana use by California university students based on gender and ethnicity. This study was important because marijuana is the most used illicit substance in the United States, and there is limited research regarding the demographic characteristics of California university students who use marijuana. The quantitative research design was used to describe the patterns of marijuana use by California university students. The setting was online. The participants included a random sample of 167 college students from five California state universities. The Daily Sessions, Frequency, Age of Onset, and Quantity of Cannabis Use Inventory was used to determine the frequency of marijuana use. An independent samples t test was used to determine if there were differences in the frequency of marijuana use based on gender, while a one-way analysis of variance was used to determine the differences in the frequency of use based on ethnicity. Caucasian males and females were in the highest use group, Asian males and females and African American females were in the mid-range use group, and Hispanic males and females were in the lowest range use group. The conclusion was California university students’ frequency of marijuana use differs based on gender and ethnicity. Recommendations for further study include increasing the number of participants and institutions of higher education, the use of trend data, and the use of a qualitative research design

Crosstalk between PTEN/PI3K/Akt Signalling and DNA Damage in the Oocyte: Implications for Primordial Follicle Activation, Oocyte Quality and Ageing

The preservation of genome integrity in the mammalian female germline from primordial follicle arrest to activation of growth to oocyte maturation is fundamental to ensure reproductive success. As oocytes are formed before birth and may remain dormant for many years, it is essential that defence mechanisms are monitored and well maintained. The phosphatase and tensin homolog of chromosome 10 (PTEN)/phosphatidylinositol 3-kinase (PI3K)/protein kinase B (PKB, Akt) is a major signalling pathway governing primordial follicle recruitment and growth. This pathway also contributes to cell growth, survival and metabolism, and to the maintenance of genomic integrity. Accelerated primordial follicle activation through this pathway may result in a compromised DNA damage response (DDR). Additionally, the distinct DDR mechanisms in oocytes may become less efficient with ageing. This review considers DNA damage surveillance mechanisms and their links to the PTEN/PI3K/Akt signalling pathway, impacting on the DDR during growth activation of primordial follicles, and in ovarian ageing. Targeting DDR mechanisms within oocytes may be of value in developing techniques to protect ovaries against chemotherapy and in advancing clinical approaches to regulate primordial follicle activation

The 'Arc of Prosperity' Revisted: Homelessness Policy Change in North Western Europe

This paper compares continuity and change in homelessness policy in Ireland, Scotland and Norway with a particular focus on the period of post-crisis austerity measures (2008–2016). The analytical approach draws on institutional theory and the notion of path dependency, which has rarely been applied to comparative homelessness research. The paper compares welfare and housing systems in the three countries prior to presenting a detailed analysis of the conceptualisation and measurement of homelessness; the institutions which address homelessness; and the evidence of change in the post-2008 period. The analysis demonstrates that challenges remain in comparing the nature of homelessness and policy responses across nation states, even where they have a number of similar characteristics, and despite some EU influence towards homelessness policy convergence. Similarly, national-level homelessness policy change could not be interpreted as entirely a result of the external shock of the 2008 general financial crisis, as existing national policy goals and programmes were also influential. Overall, embedded national frameworks and institutions were resilient, but sufficiently flexible to deliver longer term policy shifts in response to the changing nature of the homelessness problem and national policy goals. Institutionalism and path dependency were found to be useful in developing the comparative analysis of homelessness policy change and could be fruitfully applied in future longitudinal, empirical research across a wider range of countries

Some Throughput Metrics for (SOA) Application Development

Given the growing concerns about unethical usage of Information Technology (IT) becoming a major security concern, this research-in-progress paper conceptually models IS practitioner (professional) attitude toward unethical IT use. Based on the ethical notions of universalism and particularism, it argues for a two-dimensional analysis to judge development of attitude toward using IT unethically: understand the IS professional as a human being subscribing to universal principles and understand the IS professional as rooted to an organizational community of practice. Through its articulation of two powerful lenses of universalism and particularism, this paper contributes by understanding how philosophical perspectives of ethics can inform our understanding of IS security. Finally, the paper discusses future research and practice implications arising out of this conceptual treatment

Nissan's keiretsu 1956-1970

Because Toyota symbolizes the miraculous success of the Japanese automobile industry as a whole, scholars have thoroughly documented the nature of Toyota’s business strategy and its keiretsu.1 In contrast, literature exploring the nature of Nissan’s keiretsu and its business strategy was almost non-existent in the 1990s. The assumption was that the two keiretsu were identical, with similar characteristics, differences being a matter of degree.2 In this paper, I argue that the Provisional Act for the Promotion of the Machinery Industry (the Provisional Act or Kishinho), 1956-1970, enacted by the Ministry of International Trade and Industry (MITI), provided Nissan with incentives to vertically integrate some of its most important keiretsu firms; during these fifteen years, Nissan adopted hierarchy. I document how the Nissan keiretsu evolved in the period coinciding with the Provisional Act and how it differed from the Toyota keiretsu. Toyota’s inter-firm relationship with its core keiretsu members was built on trust and organizational capability, whereas Nissan’s initial postwar strategy was similar to Toyota’s only in name. Contrary to common belief, Nissan’s governance in this period was driven by transaction cost considerations in the absence of trust
