Immigrant Entrepreneurship: An Account of the Korean Experience

This research account reports conclusions from a small group of interviews done with Korean-American entrepreneurs located in three ethnic enclaves near Atlanta, GA. The purpose of this research is to further knowledge in immigrant entrepreneurship. Methodology comprised seven one-hour interviews conducted with first generation business owners (one male and six female) in three enclaves in Atlanta. The research used qualitative design and focused on answering three important questions: How do Korean entrepreneurs discover and exploit opportunities to develop business, how does this sample describe their experiences in the studied enclaves, and how might espoused cultural traits and business skills affect entrepreneurial success. It was found that these ethnic entrepreneurs started and operated their businesses in ways similar to what has been reported in prior research and similar to native-born American entrepreneurs. However, some important differences emerged. Korean electronic social media was employed in ways not previously reported. Churches provided support that may have been greater than secular enclave associations. Finally, the enclaves themselves evolved in ways different than has been reported about Korean enclaves in current literature. These findings engender the implication that the entrepreneurial experience for this population is self-contained. These topics deserve additional research

Interorganizational Learning through Exploration and Exploitation Under Conditions of Goal Divergence in Private-Public Partnerships: A Case Study

In a time when interdependence in business becomes more prevalent and necessary to maintain and sustain competitive advantage, understanding the mechanisms by which businesses relate and collaboratively adapt become central to collaborative growth and mutual success. Learning becomes central to the adaptive process. Interorganizational learning is an often challenging result of collaborative efforts. The more different the organizations are from one another, the more challenging the adaptive process and interorganizational learning. This writing addresses some of the complexities involved in collaborative learning of organizations with divergent goals through the lens of exploration exploitation phenomena. It further addresses how interorganizational learning happens between organizations that are private and public in nature. This writing is a case study that answers the question of how organizations working in collaboratives learn from each other to attain mutually beneficial results by examining two such entities in a government and private partnership. This study extends concepts of interorganizational learning as well as provides guidelines for business entities seeking to attain or sustain learning organizations. It also provides a framework from which government entities may work synergistically with private enterprise to provide competitive service to their respective demographic

Engaged Participant Observation: An Integrative Approach to Qualitative Field Research for Practitioner-Scholars

Abstract Participant observation is an appropriate research method for engaged practitioner-scholars seeking in-depth insights available from qualitative field research. Conventional approaches to participant observation include ethnography and action research. However, conventional approaches were originally developed with the assumption that the roles of practitioner and scholar are separate. We propose a new approach, engaged participant observation, which recognizes the integration of research and practice roles. We illustrate the application of engaged participant observation, and its special demands, through a completed executive doctoral dissertation conducted by second author and supervised by the first author. We address the specific tensions and demands of engaged participant observation, including issues of identity work, potentially biased interpretation, ethical conduct, and publication. Our analysis provides pragmatic guidance for conducting qualitative data collection and analysis in organizations in which the researcher is an engaged participant

Pragmatic Rigor: Principles and Criteria for Conducting and Evaluating Practitioner Scholarship

Practitioner scholarship is a promising avenue for addressing the gap between academic research and practice. To advance the objective of publishing the findings of practitioner scholarship, we develop the concept of pragmatic rigor, which is intended to complement but not replace scientific rigor. We propose four principles of pragmatic rigor: relevance, actionability, comprehensibility, and ethical reasoning. For each principle, we develop associated criteria for conducting and evaluating practical research. Pragmatic principles are relevant to the research process, from choice of topic to final evaluation by journal reviewers. We believe that applying these principles can advance the practical value of studies and help to bridge the gap between scholars and practitioners

Increased upconversion performance for thin film solar cells a trimolecular composition

Photochemical upconversion based on triplet triplet annihilation TTA UC is employed to enhance the short circuit currents generated by two varieties of thin amp; 64257;lm solar cells, a hydrogenated amorphous silicon a Si H solar cell and a dye sensitized solar cell DSC . TTA UC is exploited to harvest transmitted sub bandgap photons, combine their energies and re radiate upconverted photons back towards the solar cells. In the present study we employ a dual emitter TTA UC system which allows for signi amp; 64257;cantly improved UC quantum yields as compared to the previously used single emitter TTA systems. In doing so we achieve record photo current enhancement values for both the a Si H device and the DSC, surpassing 10 3 mA cm 2 sun 2 for the amp; 64257;rst time for a TTA UC system and marking a record for upconversion enhanced solar cells in general. We discuss pertinent challenges of the TTA UC technology which need to be addressed in order to achieve its viable device application

Towards a glacial-sensitive model of island biogeography

Although the role that Pleistocene glacial cycles have played in shaping the present biota of oceanic islands world-wide has long been recognized, their geographical, biogeographical and ecological implications have not yet been fully incorporated within existing biogeographical models. Here we summarize the different types of impacts that glacial cycles may have had on oceanic islands, including cyclic changes in climate, shifts in marine currents and wind regimes and, especially, cycles of sea level change. The latter have affected geographical parameters such as island area, isolation and elevation. They have also influenced the configurations of archipelagos via island fusion and fission, and cycles of seamount emergence and submergence. We hypothesize that these sea level cycles have had significant impacts on the biogeographical processes shaping oceanic island biotas, influencing the rates and patterns of immigration and extinction and hence species richness. Here we provide a first step toward the development of a glacial-sensitive model of island biogeography, representing the tentative temporal evolution of those biogeographical parameters during the last glacial cycle. From this reasoning we attempt to derive predictions regarding the imprint of sea level cycles on genetic, demographic or biogeographical patterns within remote island biotas

Hypogene Calcitization: Evaporite Diagenesis in the Western Delaware Basin

Evaporite calcitization within the Castile Formation of the Delaware Basin is more widespread and diverse than originally recognized. Coupled field and GIS studies have identified more than 1000 individual occurrences of calcitization within the Castile Formation outcrop area, which includes both calcitized masses (limestone buttes) and laterally extensive calcitized horizons (limestone sheets). Both limestone buttes and sheets commonly contain a central brecciated zone that we attribute to hypogene dissolution. Lithologic fabric of calcitized zones ranges from little alteration of original varved laminae to fabrics showing extensive laminae distortion as well as extensive vuggy and open cavernous porosity. Calcitization is most abundant in the western portion of the Castile outcrop region where surface denudation has been greatest. Calcitization often forms linear trends, indicating fluid migration along fractures, but also occurs as dense clusters indicating focused, ascending, hydrocarbon-rich fluids. Native sulfur, secondary tabular gypsum (i.e. selenite) and hypogene caves are commonly associated with clusters of calcitization. This assemblage suggests that calcium sulfate diagenesis within the Castile Formation is dominated by hypogene speleogemesis

Search for Gravitational Waves Associated with Gamma-Ray Bursts Detected by Fermi and Swift during the LIGO-Virgo Run O3b

We search for gravitational-wave signals associated with gamma-ray bursts (GRBs) detected by the Fermi and Swift satellites during the second half of the third observing run of Advanced LIGO and Advanced Virgo (2019 November 1 15:00 UTC-2020 March 27 17:00 UTC). We conduct two independent searches: A generic gravitational-wave transients search to analyze 86 GRBs and an analysis to target binary mergers with at least one neutron star as short GRB progenitors for 17 events. We find no significant evidence for gravitational-wave signals associated with any of these GRBs. A weighted binomial test of the combined results finds no evidence for subthreshold gravitational-wave signals associated with this GRB ensemble either. We use several source types and signal morphologies during the searches, resulting in lower bounds on the estimated distance to each GRB. Finally, we constrain the population of low-luminosity short GRBs using results from the first to the third observing runs of Advanced LIGO and Advanced Virgo. The resulting population is in accordance with the local binary neutron star merger rate. © 2022. The Author(s). Published by the American Astronomical Society
