Inclusion of persons with disabilities in mainstream employment: is it really all about the money? A case study of four large companies in Norway and Sweden

This study investigates how large companies respond to public policy measures to ensure the inclusion of persons with disabilities in mainstream employment based on a case study of four companies in Norway and Sweden. The qualitative interviews, which were conducted with company managers, government representatives in Norway, and non-governmental organisations in Sweden, revealed three overarching themes: (1) ‘legitimacy’, (2) ‘financial interests’ and (3) ‘non-financial support’. The results indicate a more proactive response from the Swedish companies, especially regarding persons with intellectual and learning difficulties. The Norwegian companies reveal a high commitment to their own employees. These findings cannot be explained solely using neo-institutional theory, which holds that organisations demonstrate ‘conformity with powerful institutional myths to strengthen support and secure survival'. The results indicate that inclusive targeted corporate policies and programmes, advisory support, and the agency and value choices of the management might matter more.     

Liquid Chromatography Mass Spectrometry-Based Proteomics: Biological and Technological Aspects

Mass spectrometry-based proteomics has become the tool of choice for identifying and quantifying the proteome of an organism. Though recent years have seen a tremendous improvement in instrument performance and the computational tools used, significant challenges remain, and there are many opportunities for statisticians to make important contributions. In the most widely used "bottom-up" approach to proteomics, complex mixtures of proteins are first subjected to enzymatic cleavage, the resulting peptide products are separated based on chemical or physical properties and analyzed using a mass spectrometer. The two fundamental challenges in the analysis of bottom-up MS-based proteomics are: (1) Identifying the proteins that are present in a sample, and (2) Quantifying the abundance levels of the identified proteins. Both of these challenges require knowledge of the biological and technological context that gives rise to observed data, as well as the application of sound statistical principles for estimation and inference. We present an overview of bottom-up proteomics and outline the key statistical issues that arise in protein identification and quantification.     

Financial crises and bank failures: A review of prediction methods

In this article we provide a summary of empirical results obtained in several economics and operations research papers that attempt to explain, predict, or suggest remedies for financial crises or banking defaults; we also outline the methodologies used in them. We analyze financial and economic circumstances associated with the US subprime mortgage crisis and the global financial turmoil that has led to severe crises in many countries. The intent of this article is to promote future empirical research for preventing bank failures and financial crises.     

Governance strategy and costs: board compensation in Sweden

Shareholders are not identical, but differ in their objectives and actions. One difference is the level of delegation of the principal functions to the board, which we suggest can be observed through the level of directors’ compensation. We analyze the difference in board compensation through the concept of governance strategy and suggest two distinct categories of shareholder strategies: the company governance strategy and the financial governance strategy. These strategies create different distributions of governance costs, which we separate into principal costs and agency costs. We claim that the financial governance strategy adopts a higher level of delegation, which implies that the principal costs are assumed by the corporation and that agency costs are higher. This in turn can explain the higher compensation for the directors of the board compared to compensation under the company governance strategy. We test our hypothesis using a three-year panel of Swedish listed corporations and find that shareholders pursuing a financial governance strategy are associated with higher levels of board compensation. These findings suggest the existence of differences in governance strategies, reflected in governance costs through board compensation, among different types of shareholders in a corporation.     

Formal adult education and socioeconomic inequality: Second chances or Matthew Effects?

In countries around the world, population aging, technological change, and labor market transformations are leading to an increasing incidence of mismatch between the skills and credentials held by workers and those required by their jobs. This is leading large numbers of people to return to schooling to enhance their prospects in the workplace. Access to adult education is highly stratified, and the returns to educational re-entry vary across social categories. This state-of-the-art paper focuses on two aspects. First, it examines the degree to which adult education (specifically, degree-bearing education) most benefits the less advantaged and thus mitigates socioeconomic inequality (second chance effects). Second, it addresses the degree to which the benefits of adult education go primarily to those who are already advantaged (Matthew Effects). Our review adopts the perspective of the socioeconomic life course and is explicitly cross-nationally comparative.     

Transition,Connection, Disconnection,and Social Media: Examining the Digital Lived Experiences of Transgender Individuals

In light of persistent discrimination, many individuals who are transgender lack a safe space to connect with others. Social media has become a platform for establishing social ties, receiving education, and sharing of resources that may not otherwise be available to individuals on the margins of society. Yet little is understood about the role of social media in the lives of individuals who are transgender. In this qualitative study, the researchers examined the experiences of adults who are transgender (N = 5) who use social media. The current study also explored possible benefits and hindrances of social media for individuals who are transgender. Two main themes emerged: social media as a resource and a path to self and authenticity. The researchers encourage counselors to become familiar with various social networking sites and their privacy settings, and propose using a theoretical framework to guide counseling work with individuals who are transgender to reflect on social media connections and disconnections.     

Optimal two-stage group-sequential designs

We derive optimal two-stage adaptive group-sequential designs for normally distributed data which achieve the minimum of a mixture of expected sample sizes at the range of plausible values of a normal mean. Unlike standard group-sequential tests, our method is adaptive in that it allows the group size at the second look to be a function of the observed test statistic at the first look. Using optimality criteria, we construct two-stage designs which we show have advantage over other popular adaptive methods. The employed computational method is a modification of the backward induction algorithm applied to a Bayesian decision problem.     

Nikolai Gogol'’s Self-Fashioning in the 1830s: The Postcolonial Perspective

This study examines Gogol'’s complex self-fashioning during the time of the creation and reception of his Ukrainian tales Vechera na khutore bliz Dikan'ki [Evenings on a Farm near Dikan'ka] (1831–1832) in light of the postcolonial concept of mimicry. Gogol'’s self-fashioning is studied through his submission to the symbolic power responsible for branding him as the Other in imperial Russian culture, as well as through his deliberate strategy of mimicry. Not only did Gogol'’s marginal social status and his Ukrainian ethnicity create a social hierarchy responsible for fashioning him as “an outsider within” imperial culture, Gogol' himself engaged in the colonial mimicry, trying to reverse the colonial gaze that imagined him as a “sly” Ukrainian. Challenging the accepted view of Gogol' as one who internalized the colonial stereotype of a “sly” Ukrainian, this study treats Gogol'’s identity as strategic, positional, and ambivalent. The first part of the study focuses on the manipulation of stereotypes of the Other within the Russian nationalist imagination in the early 1830s; the second part examines Gogol'’s ambivalent visual self-representation and social performance that simultaneously mimicked and menaced the colonial authority.     

Predicting children's internalizing symptoms across development from early emotional reactivity

Current methods of assessing children's emotional reactivity fail to capture individual differences in emotion across contexts that may be meaningfully related to youth psychopathology. We therefore explored the utility of modeling variability in young children's positive and negative emotion across emotionally evocative laboratory tasks to predict later adjustment. At age 3, 409 children completed a battery of laboratory tasks eliciting either positive or negative affect. We used latent difference score (LDS) modeling to predict children's caregiver-reported internalizing symptoms across ages 3, 5, 8, and 11 from variability in their observer-rated positive and negative emotion across laboratory tasks. We found that sex moderated the association between both average and variability measures of children's negative emotion at age 3 and trajectories of their anxious-depressive symptoms across childhood. Measures of emotion variability predicted children's internalizing symptoms above and beyond measures of average emotion. Variability indices also provided unique information about the trajectories of children's symptoms. We discuss implications for the utility of LDS modeling in assessing children's emotional reactivity.     

Searching for innovation: Product,process, and business model innovations and search behavior in established firms

Prior research indicates that search practices are an important part of the innovation process. But where established firms search for different innovation types is not clear. Drawing on knowledge-based theory of innovation and using state-of-the-art statistical techniques (copula with Bayesian inference), we find that established firms predominantly rely on several external sources (broad external search) when introducing new business models, on internal and external sources with high intensity (deep search) when innovating processes, and on broad and deep external search when innovating products. We explain that broad external search is important for business model innovation (BMI) because increased exploration is needed when introducing new business models that rely on general rather than specialized technical or tacit business knowledge. We contribute to the innovation and business model literatures by nuancing the differences between innovation types (BMI, product, and process innovation) and the associated search behavior. It is important to consider these differences because they give us clues to understand how established firms can explore unfamiliar territories through BMI.
