Time to Help? Contextualizing Trajectories of Organizational Citizenship Behavior.
Show summary
Organizational citizenship behavior (OCB) has been found to vary over time, but its longitudinal development has remained unexplored. Drawing from event system theory and human capital theory, we investigate the development of OCB over time and contextualize it with events in the organization that affect employees and their work tasks and with resources provided through human resource management (HRM) practices. The longitudinal growth model was tested in a sample of 205 employees with monthly measures over one year. For each event, we found distinctive trajectories of OCB. Furthermore, the HRM practices of selective staffing and training influenced OCB at the onset of an event, whereas the HRM practices of decision making, performance management, and promotional opportunities determined the level and the development of OCB after the event reorganization. Our contextual view of the development of OCB helps in understanding what motivates employees to perform OCB and what resources support discretionary behavior.

How lower and upper limit estimates influence judgments and evaluations.
Show summary
Uncertain or approximate quantities are in daily life often described by lower or upper limit estimates: ?more than 120 people killed?, ?a maximum 100-words abstract?. These estimates can be exclusive (more than, less than) or inclusive (minimum, maximum), leading to widely different intervals, dependent upon whether the estimates concern a single value or a distribution. Lower and upper limits pragmatically function as reference points, leading to framing effects. Shoes that cost ?more than X? are considered expensive, ?less than Y? implies that they are cheap, even when Y > X. Sales ?above X? indicate a rising trend, regardless of X.

VDU-work and the preferred line-of-sight after long term exposure to different monitor placements.
Show summary
Inconsistent results are reported by studies investigating subjective preference of vertical line-of-sight during nearwork. However, these studies are constrained by the short time allocated to familiarisation with unusual target/monitor locations. In the present work, subjective preferences were studied two years after the termination of a one-year field experiment, investigating the effect of different line-of-sight angle in VDU work. The results showed that most participants preferred to leave the desktop and monitor adjustments as they were set in the original experiment. The result stress the decisive importance of psychological factors and adjustment time and, thereby, questions the validity of the short time periods usually given to become accustomed to new monitor placements in studies investigating preferred line-of-sight in VDU-work.

VISION AND BODY, INTEGRATED SYSTEMS IN SYSTEMIC INTERPLAY.
Show summary
Based on an ecological analysis of the visual system, a systemic model is proposed linking visual stress and symptoms in other parts of the body. The model links the interaction between the oculo-motor system and other body muscles to the slow-acting mechanism of Scohr's two-step theory of vergence control. Implications of the model have been examined in a field study. The results indicate that increased closeness between natural near work and VDU-work yield reduced symptoma-tology not only for eye symptoms but also for visually related symptoms in a broader sense.

VDU-work with downward gaze. The emperor's new clothes or scientifically sound?
Show summary
Lower monitor placements, with gaze angles to the centre of the screen
30º- 45º below the horizontal line are proposed as an alternative to
higher monitor placements advocated by prevailing guidelines. A
scientific basis for this proposition has been established within a
compre-hensive theoretical framework, founded on an ecological systemic
approach to vision. A review of the literature shows reduced visual
strain and a strong tendency toward reduced symptomatology in subjects
working with downward gaze. Increased musculoskeletal load is not
evident in m. trapezius, while a clinically insignificant increase
might be present in some other the neck and shoulder muscles. Research
studying subjective preferences is inconclusive at present. The
evidence indicates that lower monitor place-ments result in less strain
on the total network of muscles involved in VDU work.

Health consequenses and behavioural changes associated with work with visual display units (VDU) � an empirical investigation.
Psykologisk Institutt, Universitetet i O.
ISSN 82-569-2089-0.
Show summary
The implementation of information technology (IT) in modern work life has lead to a growing concern about negative health effects associated with visual display units (VDU). Despite abundant research and honourable ergonomic effort within this field, it has proven difficult to obtain substantial health effects from traditional ergonomic optimisations.
The aim of this dissertation was to further the understanding of some specific factors associated with health problems in VDU work. Further, the aim was to contribute to the general understanding of the aetiology behind health problems and behavioural changes associated with VDU work. To accomplish this, four empirical studies were conducted, one laboratory study and three field studies.
Paper I addressed questions about workstation design. The results show that forearm support reduces musculoskeletal load for both mouse work and keyboarding. Moreover, shifting between sitting and standing appears to be beneficial for the musculoskeletal system. Paper II discussed possible health effects from protective VDU screen filters. The results did not demonstrate any remedial effect of such filters. The results point to participant reactivity as a plausible explanation for positive findings previously reported in short-term studies. Paper III addressed questions about vertical monitor placement. That study supported previous laboratory research by showing a range of positive health effects from lower monitor placements. Paper IV discussed the importance of office lighting. The results revealed that proportions of indirect and direct lighting did not affect health and behaviour, provided that glare was removed as a source of environmental stress.
The results of the four papers were interpreted within a new theoretical framework, the Evolutionary Stress Model (ESM). The ESM stresses the importance of developing work environments that fits with our evolutionary adaptations. Taken together, the presented results concur with predictions made from this model. On this basis, it seems pertinent to recommend the model as a theoretical framework for future research in ergonomics and human factors.

Show summary
Intervensjonsstudien "Den elektroniske skjermarbeidsplassen" har vært gjennomført som en toårig eksperimentell feltstudie der formålet har vært å utvikle kunnskap om faktorer som påvirker belastningsforholdene ved skjermarbeid. Konkret har man har undersøkt helse-effekter av optimalisering av kontormiljø med nedsenket skjerm versus optimalisering av kontormiljø med normalplassert skjerm. I tillegg har man undersøkt helse-effekter av optisk fullkorrek-sjon versus standard optometrisk korreksjonsprosedyre. Intervensjonene har vært gjennomført serielt, noe som har gitt muligheter for å be-regne enkelt-effekter av hver faktor i tillegg til even--tuelle sam-spillseffekter. Resultatene har vært samlet inn ved følgende metoder: Et selv-administrert spørreskjema, en klinisk helse-undersøkelse, en optometrisk undersøkelse samt EMG-opptak under 45 minutter normal-arbeid. Resultatene fra skjermintervensjonen viser redusert plageut-vikling blant skjermarbeidere med nedsenket skjerm både på subjektive og objektive kriterier. Når det gjelder gruppen med standard skjermplassering finner vi endringer i begge retninger. Det er derfor mer usikkert om optimaliseringen i henhold til gjeldende standard har gitt redu-sert plage-utvikling. Resul-tatene fra den optiske intervensjonen viser at effekten av arbeids-plass-briller er hovedsakelig knyttet til synsplager, med mest markert effekt i arbeids-situa-sjonen. Når det gjelder forskjeller mellom de to korreksjons-regimene gjorde forhold i intervensjonsstudien det umulig å foreta en slik sammenligning på en tilfredsstillende måte. Det ble ikke påvist noen interaksjonseffekt mellom korreksjon og skjermposisjon.
