New Technologies, Workplace Organisation and the Age Structure of the Workforce: Further Evidence Using the REPONSE Survey

This paper investigates the relationships between new technologies, innovative workplace practices, exports and the age structure of the workforce in a sample of French establishments. We confirm and expand results previously found by Aubert, Caroli and Roger (2004). The share of older workers is lower in innovative firms and the opposite holds for younger workers, both in services and manufacturing industries. This age bias is also evidenced within occupational groups (both high-skill and low-skill). Older workers are affected through both lower inflows and higher outflows. However, we also find evidence that some innovative workplace practices, e.g. delayering or decentralisation of decisions, are associated with a higher share of older workers.new work practices, technology, older workers, labour demand

Validation of Memory Accesses Through Symbolic Analyses

International audienceThe C programming language does not prevent out-of- bounds memory accesses. There exist several techniques to secure C programs; however, these methods tend to slow down these programs substantially, because they populate the binary code with runtime checks. To deal with this prob- lem, we have designed and tested two static analyses - sym- bolic region and range analysis - which we combine to re- move the majority of these guards. In addition to the analy- ses themselves, we bring two other contributions. First, we describe live range splitting strategies that improve the effi- ciency and the precision of our analyses. Secondly, we show how to deal with integer overflows, a phenomenon that can compromise the correctness of static algorithms that validate memory accesses. We validate our claims by incorporating our findings into AddressSanitizer. We generate SPEC CINT 2006 code that is 17% faster and 9% more energy efficient than the code produced originally by this tool. Furthermore, our approach is 50% more effective than Pentagons, a state- of-the-art analysis to sanitize memory accesses

Do breast implants after a mastectomy affect subsequent prognosis and survival?

In a large study, published in this issue of Breast Cancer Research, Le and colleagues report that women receiving implants after mastectomies for early-stage breast cancer experience lower breast cancer mortality than women not receiving implants. Assessment of survival patterns among women receiving reconstructive implants is complex given unique patient characteristics, disease attributes, and treatment patterns. The interpretation of reduced mortality from breast cancer must be assessed in light of significantly reduced risks of death from most other causes. In contrast, patients receiving post-mastectomy implants had elevated rates of suicide, consistent with findings among women with cosmetic implants. Additional well-designed investigations are needed to clarify survival patterns among women receiving reconstructive implants

Health-seeking behaviors and health information gathering in older Mexican American males

Evidence suggests that men's health disparities are linked to attitudes and beliefs toward health promotion and risk reduction, participation in high-risk behaviors, and limited health care access and use influenced by socioeconomic challenges. However, we know less about the specific factors related to health disparities in older Mexican American males. The purpose of this study was to explore the cultural. social, environmental, and gender factors influencing health-seeking behaviors and health information gathering in older Mexican American males. In-depth interviews were conducted with 14 older Mexican American males aged 65-80 years. Based on language preference, interviews were conducted in either Spanish or English. A standardized moderator's guide was used to examine the participant's perceptions of health, maintenance of health, gender influences on health, and sources of men's health information and health promotion programs. Data were collected, organized, and analyzed following the methodology of transcendental phenomenology and the social ecological model. Two major themes related to health-seeking behaviors and health information gathering emerged: (a) top external sources heeded include women, health care providers, and the Internet and (b) men regard inner prompts for self-determined self-care. Future research should consider these external sources and inner prompts when developing targeted health promotion interventions, such as physical activity programs, with older Mexican American males.This item from the UA Faculty Publications collection is made available by the University of Arizona with support from the University of Arizona Libraries.
