Effective assertive behavior in the workplace: Responding to unfair criticism

A social rules perspective was employed to identify the elements of socially appropriate responses to unfair criticism in the workplace. Women generally endorsed for themselves response strategies based on stronger obligation and softer rights components, while men endorsed responses based on stronger personal rights expression and weaker obligation components. In support of the utility of a social rules approach to operationalizing context-specific expectations, behavioral responses based on gender and status-specific rules were evaluated as more effective on task, relationship, and self-respect dimensions than were rights-only, rights-plus-empathy, or submissive strategies. Results are discussed in terms of the development of a context-specific model of interpersonal competence and implications for interpersonal skills and assertion training.

Integrating technology in the workplace for people with spinal cord injury

Computer technology can overcome mobility and functional limitations resulting from spinal cord injury (SCI) and enable re-employment. This study aimed to identify barriers and supports to effective technology use at work from the unique perspectives of technology users themselves. A qualitative research design was used to explore the perspectives of 11 technology users with SCI. In-depth, open-ended interviews and observations were conducted at each person’s workplace. Five major themes emerged: identifying the best or right technology; acquiring the technology; customizing and learning to use the technology; supporting the technology; and empowerment. Understanding these consumer perspectives enables professionals to empower people with SCI to optimize their work potential.

Consumer-identified barriers and strategies for optimizing technology use in the workplace

Purpose. This article explores the experiences of 26 assistive technology (AT) users having a range of physical impairments as they optimized their use of technology in the workplace. Method. A qualitative research design was employed using in-depth, open-ended interviews and observations of AT users in the workplace. Results. Participants identified many factors that limited their use of technology such as discomfort and pain, limited knowledge of the technology's features, and the complexity of the technology. The amount of time required for training, limited work time available for mastery, cost of training and limitations of the training provided, resulted in an over-reliance on trial and error and informal support networks and a sense of isolation. AT users enhanced their use of technology by addressing the ergonomics of the workstation and customizing the technology to address individual needs and strategies. Other key strategies included tailored training and learning support as well as opportunities to practice using the technology and explore its features away from work demands. Conclusions. This research identified structures important for effective AT use in the workplace which need to be put in place to ensure that AT users are able to master and optimize their use of technology.

Renal and hepatic accumulation of cadmium and lead in the expression of CYP4F2 and CYP2E1

The present study examined accumulation of the metal toxins cadmium (Cd) and lead (Pb) in relation to the abundance of cytochrome P450 4F2 (CYP4F2), CYP2E1 and concentrations of zinc and copper in liver and kidney samples using immunoblotting coupled with metal analysis. The post mortem liver and kidney cortex samples were from 23 males and 8 females aged 3-89 years. All were Caucasians who had not been exposed to metals in the workplace. Average kidney cortex Cd load of 17.4 mu g/g w.w. was 17 times greater than average liver Cd load (1.1 mu g/g w.w.). In contrast, average kidney cortex Ph load of 0.09 mu g/g w.w. was two times lower than liver Pb load of 0.19 mu g/g w.w. Average Zn and Cu concentrations in the kidney cortex samples were 67% and 33% lower than those in the liver. Liver and kidney Cd loads, but not liver or kidney Ph loads, correlated positively with donors' age. After controlling for liver Cd load, an inverse correlation was seen between Zn and age (partial r = -0.39, P = 0.02), suggesting reduction in liver Zn levels in old age. Liver CYP2E1 protein abundance correlated with age-adjusted Cd load (partial r = 0.37, P = 0.02) whereas kidney CYP4172 protein abundance showed a positive correlation with age-adjusted Cd loads (partial r = 0.40, P = 0.02). These findings suggest that Cd may be an inducer of renal CYP4172 and hepatic CYP2E1 and that increased renal CYP4172 expression may implicate in Cd-linked renal tubular dysfunction and high blood pressure, involving CYP4F2-dependent arachidonic acid metabolism.
