Competitive Dynamics between Multinational Enterprises and Local Internet Platform Companies in the Virtual Market in China

We adopt the dynamic capability perspective and the institutional view as the guiding theoretical lenses to explain the relative performance of foreign internet platform companies (IPCs) operating in China. Based on data obtained from 51 interviews a multiple‐case‐study approach is adopted, with representative matched cases between foreign IPCs, including Google, eBay, Amazon and Groupon, and local IPCs. The findings highlight the unique characteristics of the IPCs and the Chinese context that challenge assumptions prevailing in the literature of the applicability of firm‐specific advantages in determining a sustainable competitive advantage. We highlight the dynamic capabilities of the firm, such as flexibility and experimentation, in contributing to sustainable competitive advantage. Further, rather than focusing on firm‐specific resources, we find that the active agency of the firm can approach institutions as resources through external links with diversified institutional players, which is crucial for multinational enterprise IPCs to develop sustainable competitive advantage. Drawing on the findings we present a number of propositions and implications for theory and practice.     

Knowledge Accession and Knowledge Acquisition in Strategic Alliances: The Impact of Supplementary and Complementary Dimensions

This paper advances the concepts of knowledge accession and knowledge acquisition in strategic alliances by identifying supplementary and complementary dimensions to these knowledge transfer modes. Complementary knowledge transfer reflects the similarity of knowledge that the partners have and is conducted in pursuit of higher efficiency and productivity to enhance partner firms' existing competitiveness. Supplementary knowledge transfer occurs when partners each possess distinctive core competences and the information that is acquired or accessed increases the business scope of partners. As knowledge accession entails knowledge amalgamation that does not involve organizational learning, costs associated with the transfer process are lower and trust is easier to establish than in the case of knowledge acquisition. The paper reviews the implications of these transfer modes on trust building in alliances and their costs implications and presents a number of propositions for further exploration.     

Bias in linear model power and sample size due to estimating variance

Planning a study using the General Linear Univariate Model often involves sample size calculation based on a variance estimated in an earlier study. Noncentrality, power, and sample size inherit the randomness. Additional complexity arises if the estimate has been censored. Left censoring occurs when only significant tests lead to a power calculation, while right censoring occurs when only non-significant tests lead to a power calculation. We provide simple expressions for straightforward computation of the distribution function, moments, and quantiles of the censored variance estimate, estimated noncentrality, power, and sample size. We also provide convenient approximations and evaluate their accuracy. The results allow demonstrating that ignoring right censoring falsely widens confidence intervals for noncentrality and power, while ignoring left censoring falsely narrows the confidence intervals. The new results allow assessing and avoiding the potentially substantial bias that censoring may create.     

The estimation of missing observations in related time series data: Further results

Earlier work has provided an efficient method for the prediction of missing data in a dependent variable series using a system of grouped regression equations. This paper extends the previous literature in two ways. First, a test statistic capable of indicating the advantage of the grouped procedure is derived. Second, it is demonstrated through an empirical application that the most prevalent methodology used for examining the impact of financial economic events is a special case of the missing data estimation problem.     

Development of a Performance Assessment Capability in the Waste Management Programs of the U.S. Nuclear Regulatory Commission

The U.S. Nuclear Regulatory Commission (NRC) staff has developed a performance assessment capability to address three programmatic areas in nuclear waste management: high-level waste, low-level waste, and decommissioning of licensed facilities (license termination). The NRC capability consists of: (1) methodologies for performance assessment; (2) models and computer codes for estimating system performance; (3) regulatory guidance in various forms, such as regulations, Branch Technical Positions, and Standard Review Plans; and (4) a technical staff experienced in executing and evaluating performance assessments for a variety of waste systems. Although the tools and techniques are refined for each programmatic area, general approaches and similar issues are encountered in all areas.     

MATCHED PAIRS DISCRIMINATION: METHODOLOGY AND AN INVESTIGATION OF CORPORATE ACCOUNTING POLICIES

The matched-pairs methodology is becoming increasingly popular as a means of controlling extraneous factors in business research. This paper develops discriminant procedures for matched data and examines the properties of these methods. Data from a recent study by Hunt [14] on the determinants of inventory method choice are used to contrast the performance of the different methods. While all of the methods yield the same set of discriminating variables, those procedures that allow for the dependence among observations within a pair provide greater classificatory power than traditional multivariate techniques.     

Effects of intensive longitudinal data collection on pregnancy and contraceptive use

We use an experiment based on the relationship dynamics and social life study of sexual behavior, pregnancy, and contraceptive use to investigate whether participation in weekly self-reports over one year result in differential effects on related behaviors and attitudes, compared to participation in a one-time follow-up interview requiring retrospective self-reporting for the prior year. We randomly assigned 200 subjects to either a control group or a journal group. All subjects were interviewed at the beginning of the study (baseline interview) and 12 months later (closeout interview). Subjects in the journal group also completed a five-minute web- or phone-based survey every week during the 12-month study period. We found no statistically significant difference in pregnancy rates across the two groups at closeout. Contrary to our expectation, the control group experienced a slightly larger increase in having ever used a contraceptive method, although this was mainly due to increases in the least effective methods, such as condoms and withdrawal. Respondents in the weekly interview group became slightly more positive toward childbearing in terms of one specific attitude measure, but not for the vast majority of measures. We conclude that intensive longitudinal data collection does not appear to have a large or consistent impact on respondents’ pregnancy, contraceptive use, or related attitudes, relative to the more standard longitudinal approach.     

Thoughts and acts of self-harm,and suicidal ideation,in online gamblers

Gambling problems have been linked to suicidal ideation and enhanced risk of suicide attempts. However, we know very little about the factors associated with either thoughts or acts of self-harm amongst people who gamble. A web-based study of 4125 online gamblers (79% males; mean age 35.5 years), analysed using hierarchical multiple regression, revealed that self-reported non-gambling-related self-harm was negatively related to age and marital status, and positively related to problematic alcohol use. Self-reported acts of self-harm both related and unrelated to gambling were associated with drug misuse. Thoughts and acts of gambling-related self-harm were associated with problem gambling, gambling involvement and parental problem gambling. All types of self-harm were associated with mood disorder symptoms, unemployment and certain gambling motivations. When tailoring assessment and interventions for individuals at risk for gambling-related deliberate self-harm, it is important to recognize that contributory factors may include some that differ from those for deliberate self-harm in general, and that there is potential value in evaluating gambling involvement and motivations, and history of parental gambling.     

Father-daughter incest: data from an anonymous computerized survey

Retrospective data were entered anonymously by 1,521 adult women using computer-assisted self-interview. Nineteen were classified as victims of father-daughter incest, and 241 were classified as victims of sexual abuse by an adult other than their father before reaching 18 years of age. The remaining 1,261 served as controls. Incest victims were more likely than controls to endorse feeling damaged, psychologically injured, estranged from one or both parents, and shamed by others when they tried to open up about their experience. They had been eroticized early on by the incest experience, and it interfered with their adult sexuality. Incest victims experienced coitus earlier than controls and after reaching age 18 had more sex partners and were more likely to have casual sex outside their primary relationship and engage in sex for money than controls. They also had worse scores on scales measuring depression, sexual satisfaction, and communication about sex than controls.
