Holding on to Steel: Pittsburgh Culture in the Age of Globalization

In the first half of the twentieth century, Pittsburgh stood at the crossroads of relentless work, immense industrial output, and immigrant culture. The city became notorious for immense steel output. Gone are the days of Pittsburgh as ‘hell with the lid taken off’, as the downfall of the steel industry made way for a post-industrial region now largely defined by the service sector. Many factors combined to bring about the decline of heavy industry in and around Pittsburgh, one of which was the process of globalization, found in increased competition abroad and the demand for technological improvements in steel manufacturing. Economic transformation and social dislocation resulted. Globalization triggered a drastic economic episode, which had lasting effects on Pittsburgh culture. The decline of industry in Pittsburgh in the 1980s altered the commercial makeup of the region, which spurred greater attention to industrial cultural markers. This paper argues that the downfall of industry eroded the foundational symbols on which Pittsburgh culture formed, leading to active attempts to preserve many of them.     

The loss-averse newsvendor problem

Newsvendor models are widely used in the literature, and usually based upon the assumption of risk neutrality. This paper uses loss aversion to model manager's decision-making behavior in the single-period newsvendor problem. We find that if shortage cost is not negligible, then a loss-averse newsvendor may order more than a risk-neutral newsvendor. We also find that the loss-averse newsvendor's optimal order quantity may increase in wholesale price and decrease in retail price, which can never occur in the risk-neutral newsvendor model.     

Rule learning transfer across linguistic and visual modalities in 7-month-old infants

Rule learning (RL) refers to infants’ ability to extract high-order, repetition-based rules from a sequence of elements and to generalize them to new items. RL has been demonstrated in both the auditory and the visual modality, but no studies have investigated infants’ transfer of learning across these two modalities, a process that is fundamental for the development of many complex cognitive skills. Using a visual habituation procedure within a cross-modal RL task, we tested 7-month-old infants’ transfer of learning both from speech to vision (auditory-visual—AV—condition) and from vision to speech (visual-auditory—VA—condition). Results showed a transfer of learning in the AV condition, but only for those infants who were able to efficiently extract the rule during the learning (habituation) phase. In contrast, in the VA condition infants provided no evidence of RL. Overall, this study indicates that 7-month-old infants can transfers high-order rules across modalities with an advantage for transferring from speech to vision, and that this ability is constrained by infants’ individual differences in the way they process the to-be-learned rules.     

Past,Present, and Future: Editorial on Virtual Reality Applications to Human Services

Abstract

“Virtual Reality” interventions in human services may include 360° video, augmented reality, mixed reality, and fully immersive 3-dimensional virtual reality simulations. A variety of applications have been evaluated in various fields of study, including medicine, social work, psychology, and human performance training. Currently, the state of research of VR interventions in human services has primarily focused on efficacy and effectiveness research, with few studies evaluating “scaling up” or implementation of VR interventions in larger populations. Unfortunately, the state of efficacy and effectiveness studies of VR interventions still remains weak with some applications due to smaller sample sizes, lack of randomized control trials, and a gap in reporting key intervention qualities, dosage, and outcomes. With new developments in combining artificial intelligence with VR, realism and the potential for human interaction with computer generated simulations may boost presence and immersion within these applications. This editorial provides an overview of the state of virtual reality applications in human service provision, potential gaps to be addressed by research in the future, and the development of AI based interactive sequences that may boost use presence.     

Gender discourses in academic mobility

Despite increasing geographic mobility among academic staff, gendered patterns of involvement in academic mobility have largely escaped scrutiny. Positioned within literatures on internationalization, physical proximity, gender and parenthood in academic mobility and understandings of gender as a process enacted through both discursive and embodied practices, we use discourse analysis based on interviews with academics in New Zealand to examine differences in language that create differing realities with regards to gender and obligations of care in academic mobility decisions. The findings reveal how academic mobility is discursively formulated as ‘essential’ to successful academic careers, with the need for frequent travel justified despite advances in virtual communication technologies. Heteronormative discourses are shown to disrupt and fragment the opportunities female academics have to engage in academic mobility. However, we also uncover ways in which these discourses are resisted, wherein fathers articulate emotional strain associated with academic mobility. The article shows how discourse works to constitute the essentialization of academic mobility, and the uneven gendered practices associated with it, whilst also giving voice to gender inequities in academic mobility from the southern hemisphere.

Interventions Targeting Deep Tissue Lymph Nodes May Not Effectively Reduce the Risk of Salmonellosis from Ground Pork Consumption: A Quantitative Microbial Risk Assessment

The inclusion of deep tissue lymph nodes (DTLNs) or nonvisceral lymph nodes contaminated with Salmonella in wholesale fresh ground pork (WFGP) production may pose risks to public health. To assess the relative contribution of DTLNs to human salmonellosis occurrence associated with ground pork consumption and to investigate potential critical control points in the slaughter‐to‐table continuum for the control of human salmonellosis in the United States, a quantitative microbial risk assessment (QMRA) model was established. The model predicted an average of 45 cases of salmonellosis (95% CI = [19, 71]) per 100,000 Americans annually due to WFGP consumption. Sensitivity analysis of all stochastic input variables showed that cooking temperature was the most influential parameter for reducing salmonellosis cases associated with WFGP meals, followed by storage temperature and Salmonella concentration on contaminated carcass surface before fabrication. The input variables were grouped to represent three main factors along the slaughter‐to‐table chain influencing Salmonella doses ingested via WFGP meals: DTLN‐related factors, factors at processing other than DTLNs, and consumer‐related factors. The evaluation of the impact of each group of factors by second‐order Monte Carlo simulation showed that DTLN‐related factors had the lowest impact on the risk estimate among the three groups of factors. These findings indicate that interventions to reduce Salmonella contamination in DTLNs or to remove DTLNs from WFGP products may be less critical for reducing human infections attributable to ground pork than improving consumers’ cooking habits or interventions of carcass decontamination at processing.     

INTEGRATED HOUSEHOLD SURVEYS: AN ASSESSMENT OF U.S. METHODS AND AN INNOVATION

We present a vision for improving household financial surveys by integrating responses from questionnaires more completely with financial statements and combining them with payments data from diaries. Integrated household financial accounts—balance sheet, income statement, and statement of cash flows—are used to assess the degree of integration in leading U.S. household surveys, focusing on inconsistencies in measures of the change in cash. Diaries of consumer payment choice can improve dynamic integration. Using payments data, we construct a statement of liquidity flows: a detailed analysis of currency, checking accounts, prepaid cards, credit cards, and other payment instruments, consistent with conventional cash flow measures and the other financial accounts.

The nature of work and the stress of higher status

Are occupational and work conditions associated with work-to-home conflict? If so, do those associations vary by gender? Among a sample of adults in Toronto, Canada, we found that men and women in higher-status occupations reported higher levels of work-to-home conflict than workers in lower-status jobs. In addition, we observed higher levels of work-to-home conflict among workers who are self-employed and among those with more job authority, demands, involvement, and longer hours. The only significant gender-contingent effect was found for nonroutine work, which is associated positively with work-to-home conflict among men but not women. Higher levels of job demands, involvement, and hours among individuals in higher-status occupations significantly contribute to occupation-based differences in work-to-home conflict. Moreover, despite some overlap, these work conditions have largely independent associations with work-to-home conflict. Results generally support the "stress of higher status " hypothesis among both women and men. Although higher-status positions yield many rewards, such positions are not impervious to inter-role stress, and this stress may offset those rewards.
