Delay discounting in current and never-before cigarette smokers: similarities and differences across commodity,sign, and magnitude

Research has found that nicotine-dependent individuals delay discount monetary gains at a higher rate than matched controls. Delay discount rates, however, have also been found to vary across within-subject variables such as the magnitude of the outcome (e.g., 10 dollars or 1,000 dollars), whether the outcome constitutes a gain or a loss, and the commodity being evaluated (e.g., money or health). The present study comprehensively investigated the differences in delay discounting between current and never-before cigarette smokers and across these within-subject variables. Both groups exhibited a magnitude, sign, and commodity effect. Current smokers' delay discount rates for monetary outcomes, however, were higher than never-before smokers across all magnitudes and both signs. This trend was also found for delayed health outcomes, but failed to reach significance.     

From strengths use to work performance: The role of harmonious passion,subjective vitality,and concentration

Research has shown that strengths use and development can foster individual performance and well-being at work. However, to date little is known about the underlying psychological processes that might be operating in this relation. The purpose of this study was first to confirm the strengths use to work performance association and, second, to assess theoretical models of strengths use by testing a path model from strengths use to work performance, through harmonious passion, subjective vitality, and concentration. This study was conducted on a sample of 404 French-speaking Canadian workers and structural equation modeling analyses were performed in order to test the proposed model. Results show an association between strengths use and work performance. Further, this relation is completely mediated by the proposed variables. Theoretical and applied implications are discussed.     

Passion at work and burnout: A two-study test of the mediating role of flow experiences

Vallerand et al. (2003) developed a Dualistic Model of Passion where two types of passion are proposed: harmonious and obsessive passion. They generally predict adaptive and less adaptive outcomes, respectively. We hypothesized that the type of passion one holds towards his/her work should influence one's experience of burnout symptoms. We hypothesized that a harmonious passion for work would lead to low levels of burnout through its facilitation of frequent flow experiences, whereas an obsessive passion would directly lead to high levels of burnout. Two studies (one cross-sectional and one prospective) were conducted and results of structural equation modelling analyses supported the hypotheses.     

EMS Treatment of Families in an Ambiguous Out-of-Hospital Child Death: The Role of Attribution Errors

Sometimes children die from maltreatment. However, when first responders enter a scene to save the life of a dying child, the cause of the health problem cannot be immediately determined. EMS professionals are taught to enact the medically appropriate protocols in a family-centered way. This study examines five case studies of infant deaths. When there is ambiguity as to why the death might have occurred, EMS and other emergency personnel seem to be more judgmental and this attitude affects their behavior toward family members. Family members have a more difficult time coping with the loss as a result.     

The KIM-1 microcomputer as an eight-channel data logger

A machine language program and interface hardware to operate the KIM-1 microcomputer as an eight-channel data logger are described. All channels can operate simultaneously, and the data are stored in a specified area of memory. Double precision is used, enabling numbers greater than 255 to be recorded. Data can be collected over sampling intervals of 1 to 255 times 5 sec or 1 to 255 times 10 min. The time base is derived from 50- or 60-Hz mains ac. A method of transferring the data to a PET microcomputer and storing it on eight separate tape or disk files is also given.     

A cricket-song simulator using the 68705 single-chip microcomputer

A cricket-song simulator is described. The device uses a waveform generator to produce a song carrier frequency that is modulated by the 68705 microcomputer. Sixteen different songs can be stored in memory.
