PurposeThis paper examines the role of co-inventor collaboration with China and/or the USA on a country's increase in centrality in global knowledge networks. It also explores the role of specific institutional factors – corruption and intellectual property rights (IPR) protection – on this relationship.Design/methodology/approachIn the study, co-inventor data from the United States Patent and Trademark Office (USPTO) applications have been used to construct networks of technological knowledge collaboration at the country level over the years 2002–2015. Using eigenvector centrality as the dependent variable, the study uses fixed effect regression analyses on a panel of 171 countries, contributing to recent debates on knowledge networks and international cooperation.FindingsBuilding on research in economic development, innovation and social network theory, this research finds that co-patenting with Chinese inventors is positively related to a country's centrality in global knowledge networks and that this relationship is negatively moderated by collaboration with the current most central knowledge network – namely that of the USA – suggesting a substitution effect. It also finds a partial substitution between institutional factors, IPRs protection and transparency, and collaboration with China on a country's knowledge centrality.Practical implicationsRegarding policymakers, the findings can be used to encourage international collaboration for increased access to new sources of knowledge that fosters innovation while keeping a close eye on local institutions, especially emerging economies that want to increase their international knowledge network centrality.Originality/valueThis study creates a unique panel data set and extends the social networks approach in international business literature, focusing on institutional characteristics related to participation in knowledge networks.

Recruitment System

PurposeThe purpose of this paper is to examine the role of sheepskin effects in the return to education in Japan.Design/methodology/approachThe paper provides a short description of the Japanese schooling and recruitment system. It then describes the data set and the empirical approach. Estimation results are presented for the various specifications. The baseline specification closely follows existing studies for the USA to facilitate comparability across the two countries. The paper further investigates whether there are significant firm‐size differences in the estimated sheepskin effects and whether sheepskin effects disappear with increasing job tenure.FindingsThe estimation results indicate that sheepskin effects explain about 50 percent of the total returns to schooling. The paper further finds that education as a signal is only important for workers in small firms with the size of these effects being similar to comparable estimates for the USA. Finally, the estimated degree effects decrease with firm tenure, in particular for small firms. These results could be explained by the particular recruitment system of large firms in Japan, which makes university diploma as a screening device unimportant for large firms and the admission policy of Japanese universities.Originality/valueBy investigating the role of sheepskin effects in a labor market that differs substantially from the labor market in the USA, the paper provides additional insights to the human capital theory‐screening hypothesis debate.

Purpose The purpose of this paper is to present a new data set documenting various costs to starting a business across the 50 US states for the year 2011. Design/methodology/approach The first ranking weights and organizes measures using principal components analysis. The second ranking averages subcomponents of the data across groups of variables with common themes. Findings Most states largely maintain their relative position across both Methods 1 and 2 despite the difference in organization and weight of variables and groups across the two ranking methods – 21 of the top 25 states remained in the top 25 in both the Methods 1 and 2 rankings. Some states experience not insignificant changes between the two indexes and a few experience substantial changes. These changes can be attributed to the importance Method 1 places upon final fees, final processing time, and application formats for the Secretary of State. Research limitations/implications A lack of empirical evidence, additional data, and a definitive theory on the impacts of barriers to entry measures for the USA constrains both how the data are presented as well as which measures were collected. This paper attempts to accommodate for this by presenting rankings derived from different methodologies. Practical implications The composite barriers to entry measures can be used in policy analysis and possible research on rent-seeking. These data can also be used to study the determinants and relative costs of entrepreneurship. Originality/value This paper presents entry-specific regulatory measures currently undocumented in the literature.

Purpose Title II of the Jumpstart Our Business Startups Act aims to make it easier for new ventures to raise funds from accredited investors via equity crowdfunding. The purpose of this paper is to understand whether Title II equity crowdfunding represents an opportunity for women-owned companies (those that have one or more female owners/founders) to raise capital at rates similar to companies owned by men. Design/methodology/approach The authors conduct an exploratory analysis using a data set containing 6,234 Title II equity crowdfunded offerings aggregated across 17 crowdfunding platforms between September 2013 and December 2015. Findings The authors find that women-owned companies constitute only 15.2 per cent of the ventures seeking funding in this data set; however, gender had no effect on the likelihood of successful fundraising under Title II. Originality/value This study is the first to examine the roll of gender on the success of equity crowdfunding campaigns the USA. It provides empirical evidence that crowdfunding has had limited impact on democratizing access to capital for woman-owned startups and small businesses. The data reveal that woman-owned companies are underrepresented in Title II equity crowdfunding to an even greater extent than they are underrepresented in angel and venture capital (VC) investments. The results of this study also highlight the importance of examining the role of gender in equity crowdfunding across different countries.

Purpose The purpose of this paper is to report on the findings and implications associated with the millions of financial and other fraud complaints that are reported to the Federal Trade Commission and published in the Consumer Sentinel Network Data Book each year since 2002. Based on the three dimensions, namely, the number of complaints, growth rates and geographic locations of those crimes, this study found similar as well as unique trends that are new and are critical for addressing the rise of cybercrimes in the USA. The trends and patterns identified may also have implications for addressing cybercrimes in other parts of the world. Design/methodology/approach This research is a cross-sectional time-series study that covers frauds and cybercrimes in the USA from 2002 to 2015. The observed cases included the number of total complaints, complaints categories and payment amount or loss incurred both at the national and state levels. First, aggregate fraud totals, categories, payments and payment methods were analyzed and ranked. Second, state data for fraud categories, payments and filing rate per capita were organized into panel data for analysis, comparison and ranking. This cross-sectional and longitudinal approach of the different dimensions of financial and other frauds generate new rankings and more robust results. Findings The key findings are related to the long-term occurrences and trends of financial and online frauds in the USA. While some general trends are consistent with prior studies, the cross-sectional and longitudinal panel analysis produced some unique results. States that reported the most complaints do not necessarily rank high when examined with their growth per capital or their rates of growth. Their rankings could change dramatically due to other factors. In addition, eight of the top ten crime categories are the same both at the national and state levels, indicating that law enforcement could target the same crime categories. Originality/value The panel data analysis is new (first attempt at using this technique on the data set) and robust because it allows cross-sectional and longitudinally analysis of the various financial and online fraud crimes, in aggregate and by state, for a more comprehensive and comparative examination of the fraud behavioral trends. This research can be viewed as an improvement over earlier studies because the panel analysis identifies what fraud trends, scam types and payment amount exist on the national and state levels. The rate of fraud growth in the respective states provides a better understanding about future development of this problem.

Scholars have recognized emotion as an increasingly important element in the reception and retransmission of online information. In the United States, because of existing differences in ideology, among both audiences and producers of news stories, political issues are prone to spark considerable emotional responses online. While much research has explored emotional responses during election campaigns, this study focuses on the role of online emotion in social media posts related to day-to-day governance in between election periods. Specifically, this study takes the 2018–2019 government shutdown as its subject of investigation. The data set shows the prominence of journalistic and political figures in leading the discussion of news stories, the nuance of emotions employed in the news frames, and the choice of pro-attitudinal news sharing.

Clostridioides Difficile

ABSTRACT Clostridioides difficile is the leading cause of nosocomial infection and is the causative agent of antibiotic-associated diarrhea. The severity of the disease is directly associated with toxin production, and spores are responsible for the transmission and persistence of the organism. Previously, we characterized sin locus regulators SinR and SinR′ (we renamed it SinI), where SinR is the regulator of toxin production and sporulation. The SinI regulator acts as its antagonist. In Bacillus subtilis, Spo0A, the master regulator of sporulation, controls SinR by regulating the expression of its antagonist, sinI. However, the role of Spo0A in the expression of sinR and sinI in C. difficile had not yet been reported. In this study, we tested spo0A mutants in three different C. difficile strains, R20291, UK1, and JIR8094, to understand the role of Spo0A in sin locus expression. Western blot analysis revealed that spo0A mutants had increased SinR levels. Quantitative reverse transcription-PCR (qRT-PCR) analysis of its expression further supported these data. By carrying out genetic and biochemical assays, we show that Spo0A can bind to the upstream region of this locus to regulates its expression. This study provides vital information that Spo0A regulates the sin locus, which controls critical pathogenic traits such as sporulation, toxin production, and motility in C. difficile. IMPORTANCE Clostridioides difficile is the leading cause of antibiotic-associated diarrheal disease in the United States. During infection, C. difficile spores germinate, and the vegetative bacterial cells produce toxins that damage host tissue. In C. difficile, the sin locus is known to regulate both sporulation and toxin production. In this study, we show that Spo0A, the master regulator of sporulation, controls sin locus expression. Results from our study suggest that Spo0A directly regulates the expression of this locus by binding to its upstream DNA region. This observation adds new detail to the gene regulatory network that connects sporulation and toxin production in this pathogen.

Ambidextrous Leadership

Purpose The interaction between opening and closing behaviors of ambidextrous leadership produces “change” force throughout the organization in proactive response to market forces. This research aims to assess the role of ambidextrous leadership in fostering entrepreneurial orientation (EO) and market responsiveness. The research also seeks an insight into how external supply chain integration moderates the positive effect of EO on market responsiveness. Design/methodology/approach Research data were collected from 327 meso-level managers and 517 subordinates from chemical manufacturing companies in the Vietnam business context. Findings Research findings shed light on the positive effect of ambidextrous leadership on EO, which in turn contributes to market responsiveness. The moderation role that external supply chain integration plays on the EO–market responsiveness linkage was also grounded on the data set. Originality/value Through the identification of the predictive roles of ambidextrous leadership and EO for market responsiveness, the current research indicates the convergence between leadership, EO and market responsiveness research streams.

Purpose This paper aims to explain how the evolution of knowledge networks and firms’ strategic choices affect innovation. Endogenous factors associated with a path-dependent evolution of the knowledge network are jointly considered with a firm’s development of international relationships and increasing internal absorptive capacity over time. Design/methodology/approach In a biotech cluster, the authors gathered data on the firms’ characteristics and network relationships by asking about the technological knowledge they received in the cluster in 2007 and 2012 – “roster-recall” method. Estimation results were obtained using moderated regression analysis. Findings Firms that increase their involvement in knowledge networks over time also tend to increase their innovative capacity. However, efforts devoted to building international links or absorptive capacity negatively moderate the impact of network growth on innovation. Practical implications Practitioners have two alternative ways of increasing innovation inside knowledge networks: they can increase their centrality by developing their knowledge network interactions or invest in developing their internal absorptive capacity and new international sources of knowledge. Investing in both of these simultaneously does not seem to improve a firm’s innovative capacity. Originality/value Coupling firms’ strategic options with knowledge network dynamics provide a more complete way of explaining how firms can improve their innovative capacity.

ABSTRACT Campylobacter jejuni is a zoonotic pathogen, and a hypervirulent clone, named clone SA, has recently emerged as the predominant cause of ovine abortion in the United States. To induce abortion, orally ingested Campylobacter must translocate across the intestinal epithelium, spread systemically in the circulation, and reach the fetoplacental tissue. Bacterial factors involved in these steps are not well understood. C. jejuni is known to produce capsular polysaccharide (CPS), but the specific role that CPS plays in systemic infection and particularly abortion in animals remains to be determined. In this study, we evaluated the role of CPS in bacteremia using a mouse model and in abortion using a pregnant guinea pig model following oral challenge. Compared with C. jejuni NCTC 11168 and 81-176, a clone SA isolate (IA3902) resulted in significantly higher bacterial counts and a significantly longer duration of bacteremia in mice. The loss of capsule production via gene-specific mutagenesis in IA3902 led to the complete abolishment of bacteremia in mice and abortion in pregnant guinea pigs, while complementation of capsule expression almost fully restored these phenotypes. The capsule mutant strain was also impaired for survival in guinea pig sera and sheep blood. Sequence-based analyses revealed that clone SA possesses a unique CPS locus with a mosaic structure, which has been stably maintained in all clone SA isolates derived from various hosts and times. These findings establish CPS as a key virulence factor for the induction of systemic infection and abortion in pregnant animals and provide a viable candidate for the development of vaccines against hypervirulent C. jejuni.
