Dot Com

Initial public offerings (IPOs) have been a prominent focus of academic and popular press attention, especially in recent years. Much of this attention can be attributed to the increase in IPO activity as a function of the “dot com” phenomenon. Of particular interest to both academics and practitioners is IPO underpricing. Review of existing research suggests little consensus regarding those factors associated with underpricing. We provide a meta-analysis of published studies. Our findings reveal a number of significant relationships, many of which are opposite that predicted by signaling theory. Implications of these findings for practice and future research are discussed.

A complete description of the literature search, including the criteria used for the inclusion of reports after they have been located, used in a research synthesis or meta-analysis is critical if subsequent researchers are to accurately evaluate and reproduce a synthesis' methods and results. Based on previous guidelines and new suggestions, we present a set of focused and detailed standards for reporting the methods used in a literature search. The guidelines cover five search strategies: reference database searches, journal and bibliography searches, searches of the reference lists of reports, citation searches, and direct contact searches. First, we bring together all the unique recommendations made in existing guidelines for research synthesis. Second, we identify gaps in reporting standards for search strategies. Third, we address these gaps by providing new reporting recommendations. Our hope is to facilitate successful evaluation and replication of research synthesis results.

Since the seminal 1992 paper by van IJzendoorn, Sagi, and Lambermon, putting forward the “The multiple caretaker paradox”, relatively little attention has been given to the potential joint effects of the role early attachment network to mother and father play in development. Recently, Dagan and Sagi-Schwartz (2018) have published a paper that attempts to revive this unsettled issue, calling for research on the subject and offering a framework for posing attachment network hypotheses. This Collaboration for Attachment Research Synthesis project attempts to use an Individual Participant Data meta-analyses to test the hypotheses put forward in Dagan and Sagi-Schwartz (2018). Specifically, we test (a) whether the number of secure attachments (0,1, or 2) matter in predicting a range of developmental outcomes, and (b) whether the quality of attachment relationship with one parent contributes more than the other to these outcomes.

Since its inception, the field of second language research has utilized methods from a number of areas, including general linguistics, psychology, education, sociology, anthropology and, recently, neuroscience and corpus linguistics. As the questions and objectives expand, researchers are increasingly pushing methodological boundaries to gain a clearer picture of second language learning. At one end for example, we see measures of cognition (e.g., brain imaging and eye tracking) and at the other end we see exploration of issues of culture and identity (e.g., ethnographies, deep dive case studies, introspective and narrative analyses). There is an emerging emphasis on research synthesis, meta-analysis, and replication. This article illustrates a few of the advancements in methods and research agendas in SLA. I will conclude by highlighting some of the ways that second language researchers can continue to incorporate, assimilate, and shape methodology, as well as pointing out some of the potential pitfalls, and overall, how these methodological innovations benefit the field.

Analysis Of Results

Research synthesis in ecology has typically been based on literature reviews, as is also common in other fields. That is, a search is conducted for relevant data addressing a particular research question, the utility of published and unpublished data is assessed, and the results are synthesized to address questions based on all of the available evidence. This chapter discusses the case of individual researchers who wish to combine the results of distinct experiments that they have conducted themselves or within a single research group, sometimes over the course of many years. Such efforts have many similarities with literature-based quantitative research synthesis, but differ in some important ways. It begins with several examples of such work, and investigates the challenges, potential pitfalls, advantages, and issues involved in using meta-analysis for the synthesis of such large-group collaborative experimental work.
