Perceived job insecurity among dual‐earner couples: Do its antecedents vary according to gender, economic sector and the measure used?

Abstract: The aim of the study was to examine the experience and the antecedent factors of job insecurity in dual-earner couples in Finland. The data were obtained by questionnaire from a sample of 387 married or cohabiting dual-earner couples in Spring 1999. Job insecurity was defined from three viewpoints: job uncertainty, the worry over job continuity, and the probability of job-related changes. The results showed that the experience and the antecedents of job insecurity varied according to the economic sector, gender and the scale used. Generally, perceived job insecurity was more common in the private than in the public sector. Female partners were more uncertain about their job future than male partners. Psychosocial job and organizational characteristics (e.g. low job control, poor organizational communication) were the most significant predictors of job insecurity, and personal characteristics (e.g. high job involvement, low self-esteem) best predicted only the emotional aspects (i.e. worry) linked to job loss. Only a modest bidirectional crossover effect between partners was found. Perceived economic stress crossed over from one partner to another: if the man experienced a high degree of economic stress, his partner's job insecurity level was elevated and vice versa.

Wastewater Treatment and Reclamation: A Review of Pulp and Paper Industry Practices and Opportunities

Abstract: The pulp and paper (P&P) industry worldwide has achieved substantial progress in treating both process water and wastewater, thus limiting the discharge of pollutants to receiving waters. This review covers a variety of wastewater treatment methods, which provide P&P companies with cost-effective ways to limit the release of biological or chemical oxygen demand, toxicity, solids, color, and other indicators of pollutant load. Conventional wastewater treatment systems, often comprising primary clarification followed by activated sludge processes, have been widely implemented in the P&P industry. Higher levels of pollutant removal can be achieved by supplementary treatments, which can include anaerobic biological stages, advanced oxidation processes, bioreactors, and membrane filtration technologies. Improvements in the performance of wastewater treatment operations often can be achieved by effective measurement technologies and by strategic addition of agents including coagulants, flocculants, filter aids, and optimized fungal or bacterial cultures. In addition, P&P mills can implement upstream process changes, including dissolved-air-flotation (DAF) systems, filtration save-alls, and kidney-like operations to purify process waters, thus reducing the load of pollutants and the volume of effluent being discharged to end-of-pipe wastewater treatment plants.

Therapeutic group psychoeducation and relaxation in treating fear of childbirth.

Abstract: Background. The increase in the numbers of women fearing childbirth and requesting cesarean sections call for new forms of antenatal treatment. Methods. Finnish nulliparous women experiencing severe fear of childbirth (experimental group, n = 102) attended 5 group sessions with a psychologist, once together with a midwife, during the third trimester. One session was held 3 months after the delivery. Each session consisted of a discussion of fear and feelings towards the impending birth and parenthood in a psychotherapeutic atmosphere and of relaxation exercises focused on an imaginary childbirth. The results were compared with those of 85 women treated for fear of childbirth by 2 appointments with an obstetrician (conventional treatment). Results. Before the sessions, among the women in the experimental group, scored fear of childbirth, on a scale of one to ten, was 6.9±2.0 (SD), which is similar to the score of those receiving conventional treatment (6.0±1.6). After the sessions, 84 women in the experime...

Event-related potentials and autonomic responses to a change in unattended auditory stimuli

Abstract: Event-related brain potentials (ERPs) and autonomic nervous system (ANS) responses to occasional pitch and rise-time changes in a task-irrelevant auditory stimulus repeating at short intervals were measured while the subject performed a difficult intellectual task (Raven Matrices). It was found that deviant stimuli elicited the mismatch negativity (MMN) component of the ERP even when they elicited no ANS response. There was no significant difference in the mismatch negativity between trials in which the skin conductance response was or was not elicited. The pitch deviant tone also elicited heart rate deceleration, whereas the rise-time deviant tone tended to elicit a later heart rate acceleration. Neither heart rate change correlated with the mismatch negativity. The pattern of results obtained suggests that the mismatch negativity is generated by an automatic discrimination process associated with the cerebral events initiating the orienting response to stimulus change, but does not necessarily lead to the orienting response elicitation. Longer-latency ERP components tended to show slight covariation with ANS responses. The P3 was larger when a skin conductance response was elicited than when it was not elicited. Further, heart rate change trials tended to be accompanied by larger slow waves than trials with no heart rate response. Heart rate acceleration trials were accompanied by a larger slow parietal positivity and a smaller frontal negativity than were heart rate deceleration trials.
