“Mad Money” madness: Jim Cramer's image restoration effort

The following is an evaluation of “Mad Money” host Jim Cramer's image restoration attempts during his March 2009 week-long media battle with Jon Stewart, host of “The Daily Show.” Using Benoit's (1995) image restoration theory as a conceptual framework, it is apparent that Cramer failed in restoring his reputation because he frequently coupled incongruent strategies and was unable to grasp the dynamic nature of communicative image restoration.     

The Hobo Anomalous: Class,minorities and political invention in the Industrial Workers of the World

This article is an analysis of minority political invention in the Industrial Workers of the World (IWW). Against the tendency in recent social and cultural theory to dichotomize class and difference, it argues that it was in and through the IWW's formulation of class that minority political and cultural invention occurred. Using the framework of Deleuze and Guattari's minor politics, the article shows how the IWW's composition in the simultaneously diffuse and cramped plane of work operated against the major political identities and subjects of worker, immigrant, American, citizen and 'people', and towards the creation of minority political knowledges, tactics and cultural styles premised on the condition that 'the people are missing'. Seeking to understand the IWW's modes and techniques of invention, the article explores the general plane of IWW composition, its particular political and cultural expressions (in songs, manifestos, cartoons and tactics), and its minor mode of authorship. The article focuses in particular on two aspects of IWW minority composition, the itinerant worker, or hobo, and the politics of sabotage.     

Culture Within Sites,Culture as Resources,and Culture as Wider Contexts: A Typology of How Culture Works in Social Movement Theory

Sociologists of social movements agree that culture matters for studying collective action, and have proposed a variety of theoretical concepts to understand culture and mobilization, including framing, free spaces, and collective identity. Despite this, what we mean when we say “culture matters” remains unclear. In this paper, I draw on 30 years of social movement theory and research to construct a typology of three ways that culture is seen as shaping social movement activity: (i) culture renders particular sites fruitful for social movements to mobilize out of; (ii) culture serves as a resource that assists in movement action; and (iii) culture provides wider contexts that shape movement activity. This typology represents the analytic building blocks of theories about culture and social movements, and is presented towards the end of clarifying and sharpening our theoretical concepts. The paper concludes with suggestions for future research that draw on, refine, and extend these three building blocks.     

Re-Defining the Who,When, and Where of Mentoring for Professional Statisticians

Organizations tailor their mentoring strategies to accommodate internal resources and preferences, producing different approaches in academic, government, and corporate environments. Across these settings, three common barriers impede effective mentoring of statisticians: overspecialization, time constraints, and geographic dispersion. The authors share mentoring strategies that have emerged at their organization, Mathematica Policy Research, to overcome these obstacles. Practices include creating a methodology working group to unite researchers with diverse backgrounds, integrating mentoring into existing workflows, and harnessing modern technological infrastructure to facilitate virtual mentoring. Although these strategies emerged within a specific professional context, they suggest opportunities for statisticians to expand the channels through which mentorship can occur.     

Latent transition models with latent class predictors: attention deficit hyperactivity disorder subtypes and high school marijuana use

Summary.  Attention deficit hyperactivity disorder (ADHD) is a neurodevelopmental disorder which is most often diagnosed in childhood with symptoms often persisting into adulthood. Elevated rates of substance use disorders have been evidenced among those with ADHD, but recent research focusing on the relationship between subtypes of ADHD and specific drugs is inconsistent. We propose a latent transition model (LTM) to guide our understanding of how drug use progresses, in particular marijuana use, while accounting for the measurement error that is often found in self-reported substance use data. We extend the LTM to include a latent class predictor to represent empirically derived ADHD subtypes that do not rely on meeting specific diagnostic criteria. We begin by fitting two separate latent class analysis (LCA) models by using second-order estimating equations: a longitudinal LCA model to define stages of marijuana use, and a cross-sectional LCA model to define ADHD subtypes. The LTM model parameters describing the probability of transitioning between the LCA-defined stages of marijuana use and the influence of the LCA-defined ADHD subtypes on these transition rates are then estimated by using a set of first-order estimating equations given the LCA parameter estimates. A robust estimate of the LTM parameter variance that accounts for the variation due to the estimation of the two sets of LCA parameters is proposed. Solving three sets of estimating equations enables us to determine the underlying latent class structures independently of the model for the transition rates and simplifying assumptions about the correlation structure at each stage reduces the computational complexity.     

Fairness as a constraint on reciprocity: Playing simultaneously as dictator and trustee

The dictator and trust games are two common games used to identify the existence of social preferences. However, in many social interactions, individuals face the environments in both games simultaneously: for example we are often engaged in charitable donations to strangers, as well as reciprocal exchange with family members and colleagues. As giving in one game could be prioritised over giving in the other, it is important to have participants play both as a dictator in the dictator game and as a trustee in a trust game simultaneously. The results indicate that when the recipient in the dictator game is significantly poorer relative to the dictator, the dictator tends to return an amount to the trustor such that the trustor neither makes a loss nor profit from trusting. This suggests that the presence of a sufficiently strong incentive to make transfers as a dictator may completely crowd-out any monetary returns to trust.     

Žumberak: A Sixteenth-Century Refugee Settlement Zone

This article examines the movement of Orthodox Christian refugees from Bosnia to the Habsburg Monarchy in the 1530s and their settlement in a district called ?umberak. The movement of these Uskoks has never been examined in the context of refugee studies. This study of a refugee movement and settlement over a five-century period offers the possibility of reaching a better understanding of the long-term outcome of refugee movements. Ultimately, this article suggests that the refugees affected the land they settled as much as the settlement zone affected them, and that, in this case, the refugees were able to define their own outcome.     

High-intensity interval training (HIIT) increases insulin-like growth factor-I (IGF-I) in sedentary aging men but not masters’ athletes: an observational study

Introduction: The aim of this investigation was to examine the impact high-intensity interval training (HIIT) on serum insulin-like growth factor-I (IGF-I) in active compared with sedentary aging men.

Methods: 22 lifetime sedentary (SED; 62?±?2 years) and 17 masters’ athletes (LEX; 60?±?5 years) were recruited to the study. As HIIT requires preconditioning exercise in sedentary cohorts, the study required three assessment phases; enrollment (phase A), following preconditioning exercise (phase B), and post-HIIT (phase C). Serum IGF-I was determined by electrochemiluminescent immunoassay.

Results: IGF-I was higher in LEX compared to SED at baseline (p?=?0.007, Cohen’s d?=?0.91), and phase B (p?=?0.083, Cohen’s d?=?0.59), with only a small difference at C (p?=?0.291, Cohen’s d?=?0.35). SED experienced a small increase in IGF-I following preconditioning from 13.1?±?4.7 to 14.2?±?6.0?μg·dl^?1 (p?=?0.376, Cohen’s d?=?0.22), followed by a larger increase post-HIIT (16.9?±?4.4?μg·dl^?1), which was significantly elevated compared with baseline (p?=?0.002, Cohen’s d?=?0.85), and post-preconditioning (p?=?0.005, Cohen’s d?=?0.51). LEX experienced a trivial changes in IGF-I from A to B (18.2?±?6.4 to 17.2?±?3.7?μg·dl^?1 [p?=?0.538, Cohen’s d?=?0.19]), and a small change post-HIIT (18.4?±?4.1?μg·dl^?1 [p?=?0.283, Cohen’s d?=?0.31]). Small increases were observed in fat-free mass in both groups following HIIT (p?d?=?0.32–0.45).

Conclusions: In conclusion, HIIT with preconditioning exercise abrogates the age associated difference in IGF-I between SED and LEX, and induces small improvements in fat-free mass in both SED and LEX.     

The reliance on recognition and majority vote heuristics over privacy concerns when selecting smartphone apps among German and US consumers

The smartphone app market is a prime example of a digital market where consumers are tasked with selecting one option among a plethora of alternatives, at times indistinguishable from one another. Building upon findings on information processing and decision-making, we postulate that consumers follow simple (rather than complex) heuristic rules to navigate the app market. In particular, we focus on two such strategies: the recognition heuristic and the majority vote heuristic. App privacy information was also considered as a potentially salient cue in the decision-making process, given the personal data stored on smartphones. Results of a mixed-method design (behavioral analysis and think-aloud protocols) study with German (N?=?18) and US (N?=?25) students find a dominance of the recognition heuristic. Decisions are further supported by majority vote heuristics. Privacy information is largely disregarded, particularly by US participants. Implications for app market design and engagement are discussed.
