Almost unbiased estimation in multiplicative models

In the lognormal linear models the estimation of constant term presents problems. In this paper we use weighted jackknife procedure (suggested by Hinkley 1977) for reducing the bias of the maximum likelihood estimator. The resulting estimator is unbiased upto order (1/T),T being the number of observations, and has the same MSE as that of the MLE to the same order of approximation; moreover, being the jackknife estimator it enjoys all the desirable large sample properties like any other jackknife estimator.

The content and focus of Canadian corporate codes of ethics

This paper primarily reports the findings of content analyses of seventy-five codes of ethics ofFinancial Post 500 corporations. The contents of each code were comprehensively evaluated along sixty-one criteria according to four levels. It was found that the focus of these codes was the protection of the firm. While some of them refer to issues of social responsibility, they are principally concerned with conduct against the firm.Maurica Lefebvre holds an Honours Bachelor of Arts Degree in Psychology from the University of Western Ontario and a Bachelor of Commerce degree and MBA from the University of Windsor.

Global Social Media Usage: Insights Into Reaching Consumers Worldwide

This study documents global social media usage patterns based on a large‐scale survey of 4,630 social media users around the world. The study provides insights into how users in the European Union, United States, and BRIC (Brazil, Russia, India, and China) regions use social media for business and personal use. It analyzes variability in global social media platforms being used in these different world regions. The study also presents insights into usage of multilingual content for global social media consumption and the global user propensity to translate social media. Finally, the paper showcases an innovative technology solution to help companies leverage machine and human translation to enable users to translate social media content. © 2012 Wiley Periodicals, Inc.     

Human resource management in multinational and domestic enterprises: A comparative institutional analysis in Southeast Asia

This article looks at the relative impact of context on the role of senior managers. It compares HR directors of domestic enterprises (DEs) with those of multinational enterprises (MNEs), within an emerging market setting, based on a survey of HR directors in Brunei. We found that, with the exception of some aspects of selection and recruitment, HR directors of MNEs accorded a higher priority to strategic tasks but were more reluctant to delegate. This study confirms the importance of MNEs in pioneering more modern and integrated approaches to people management but also demonstrates the limitations to the extent where they might act as evangelists of new practices that are adopted by their local peers. In contrast, local firms were more likely to concentrate their attention on administrative, rather than strategic, issues. We draw out the implications of our findings for theory and practice.

The rise of smart consumers: role of smart servicescape and smart consumer experience co-creation

ABSTRACT

Rapid technological advancements have led to the emergence of smart services and smart consumers. This study focuses on smart consumers who voluntarily engage in value creation activities, in order to conceptualise smart experience co-creation (SEC) and the smart servicescape. Drawing on the Stimulus-Organism-Response (SOR) framework, a model is proposed and tested around the impacts of smart servicescape dimensions (aesthetics, superior functionality, social presence, perceived interactivity and perceived personalisation) on smart consumer experience co-creation. SEC is conceptualised as a second-order construct consisting of cognitive, hedonic, social/personal, and pragmatic/economic first-order dimensions. Results show that the technological environmental cues of the smart servicescape (S) collectively influence smart experience co-creation (O), and this co-created experience eventually influences consumers’ service brand equity and word-of-mouth (WOM) intentions (R). A major novelty of this study lies in uncovering the relationship between experience co-creation and service brand equity. Findings have theoretical and managerial implications for smart services.     

Cost-effectiveness of second-line atezolizumab in Canada for advanced non-small cell lung cancer (NSCLC)

Aim: To assess the cost-effectiveness in Canada of atezolizumab compared with docetaxel or nivolumab for the treatment of advanced NSCLC after first-line platinum-doublet chemotherapy.

Materials and methods: A three-state partitioned-survival model was developed. Clinical inputs were obtained from the phase III OAK trial comparing atezolizumab with docetaxel in patients with advanced NSCLC who progressed after first-line platinum-doublet chemotherapy. Overall survival (OS) and progression-free survival (PFS) were extrapolated beyond the trial period using parametric models. A cure model assuming a 1% cure fraction was fitted to the OS data for atezolizumab. Outcomes for nivolumab were informed by a network meta-analysis (NMA) vs atezolizumab. Resource use and costs were informed by clinical expert opinion and published Canadian sources. Utility values were obtained from the OAK trial. The perspective of the analysis was that of the Canadian publicly-funded healthcare system. The base case time horizon was 10?years, and the discount rate was 1.5% annually for both costs and effects. Scenario analyses were performed to test the robustness of the results and all analyses were performed probabilistically.

Results: Atezolizumab demonstrated a quality-adjusted life-year (QALY) gain of 0.60 compared with docetaxel at an incremental cost of $85,073, resulting in an incremental cost-effectiveness ratio (ICER) of $142,074/QALY. Atezolizumab dominated nivolumab (regardless of dosing regimen), based on modest differences in both QALYs and costs. Docetaxel was most likely to be cost effective at willingness-to-pay (WTP) thresholds below $125,000/QALY gained, while atezolizumab was most likely to be cost effective beyond this WTP threshold. In most scenario analyses, the results remained robust to changes in parameters. A reduced time horizon and alternative approaches to the NMA had the greatest impact on cost-effectiveness results.

Conclusion: Atezolizumab represents a cost-effective therapeutic option in Canada for the treatment of patients with advanced NSCLC who progress after first-line platinum doublet chemotherapy.

The effect of environmental regulations,top management commitment,and organizational learning on green product innovation: Evidence from automobile industry

This paper proposes and empirically examines a model to investigate the effect of environmental regulations, top management commitment (TMCO) and organizational learning toward green product innovation (GPI). The proposed theoretical model, grounded in dynamic capabilities view (DCV) and upper echelons theory, is analyzed by Partial least squares (PLS) method using the data from Indian automotive manufacturing firms. The findings indicate the importance of TMCO and organizational learning for implementing GPI (in response to regulations), and achieve desired performance. Further, organizational learning fully mediates between commitment of top management and GPI. The findings can be useful for managers in automotive manufacturing firms who are interested toward implementing GPI. The paper contributes to green innovation literature by empirically examining the role of TMCO and organizational learning for GPI.
