The 16th Data Release of the Sloan Digital Sky Surveys: First Release from the APOGEE-2 Southern Survey and Full Release of eBOSS Spectra

Abstract: This paper documents the sixteenth data release (DR16) from the Sloan Digital Sky Surveys; the fourth and penultimate from the fourth phase (SDSS-IV). This is the first release of data from the southern hemisphere survey of the Apache Point Observatory Galactic Evolution Experiment 2 (APOGEE-2); new data from APOGEE-2 North are also included. DR16 is also notable as the final data release for the main cosmological program of the Extended Baryon Oscillation Spectroscopic Survey (eBOSS), and all raw and reduced spectra from that project are released here. DR16 also includes all the data from the Time Domain Spectroscopic Survey (TDSS) and new data from the SPectroscopic IDentification of ERosita Survey (SPIDERS) programs, both of which were co-observed on eBOSS plates. DR16 has no new data from the Mapping Nearby Galaxies at Apache Point Observatory (MaNGA) survey (or the MaNGA Stellar Library "MaStar"). We also preview future SDSS-V operations (due to start in 2020), and summarize plans for the final SDSS-IV data release (DR17).

Entrepreneurs' Optimism And New Venture Performance: A Social Cognitive Perspective

Abstract: Previous research indicates that entrepreneurs are generally high in dispositional optimism—the tendency to expect positive outcomes even when such expectations are not rationally justified. Findings of the current study demonstrate a negative relationship between entrepreneurs' optimism and the performance (revenue and employment growth) of their new ventures. Past experience creating ventures and industry dynamism moderated these effects, strengthening the negative relationship between entrepreneurs' optimism and venture performance. These findings illustrate the benefits of applying a social cognitive perspective toward efforts to understand key aspects of the new venture creation and development process.

Leadership Effectiveness in Global Virtual Teams

Abstract: The trend toward physically dispersed work groups has necessitated a fresh inquiry into the role and nature of team leadership in virtual settings. To accomplish this, we assembled thirteen culturally diverse global teams from locations in Europe, Mexico, and the United States, assigning each team a project leader and task to complete. The findings suggest that effective team leaders demonstrate the capability to deal with paradox and contradiction by performing multiple leadership roles simultaneously (behavioral complexity). Specifically, we discovered that highly effective virtual team leaders act in a mentoring role and exhibit a high degree of understanding (empathy) toward other team members. At the same time, effective leaders are also able to assert their authority without being perceived as overbearing or inflexible. Finally, effective leaders are found to be extremely effective at providing regular, detailed, and prompt communication with their peers and in articulating role relationships (responsibilities) among the virtual team members. This study provides useful insights for managers interested in developing global virtual teams, as well as for academics interested in pursuing virtual team research.

International venturing by emerging economy firms: the effects of firm capabilities, home country networks, and corporate entrepreneurship

Abstract: Past literature on foreign direct investment generally supports an economics perspective that there is a direct relationship between firm-specific ownership advantages and international expansion. However, in emerging economies, with their institutional environment context characterized by low resource munificence and continuous economic liberalization, a theoretical extension of the current perspective is needed. This paper introduces new parameters by focusing on specific ownership advantages and strategic actions that firms have to develop in response to the institutional characteristics of the emerging economies when they decide to pursue outward FDI. The focus here is on international venturing that requires a firm to engage in activities for new business creation in a foreign country rather than simply seek to distribute a product in another nation. It is shown empirically that the relationship between firm-specific ownership advantages and international venturing is moderated by the degree of home industry competition and export intensity. In addition, such a relationship is mediated by the intensity of corporate entrepreneurial transformation in the form of innovation, new business creation, and strategic renewal.
