Information Systems Use as a Result of External Influences

- The use of an information system (IS) can be studied as a result of all the efforts that an organization has put on the introduction of IS, as for example change management, user training, support training and proper technical infrastructure. The description takes its starting point in the organization per se, whilst the one in this paper is external. In this paper, a complementary perspective is offered that can explain the final use of an IS, illustrated by three empirical papers. The use of an IS can be a result of the interorganizational influences as customers, suppliers or other stakeholders. The paper shows that the external environment has a direct effect on how the user experiences an IS and uses it.

SIMTER: a Multi-Aspect Virtual Production System Evaluation Tool.

- Production systems consist of complex combinations of human-and-machine interactions, material flows, energy transitions and workflows. Additionally, production enterprises are challenged with handling the environmental impacts and societal effects of their processes – including workplace ergonomics. One way of testing different system solutions quickly, early and at low cost (or consequence) is to use computer-based simulation. This paper introduces the production simulation tool SIMTER, which allows users to build a 3D animated model of a human-machine work system and explore the output consequences of different Levels of Automation (ranging from letting tasks be performed by either a human worker, a human worker using a range of tools, or an automated machine). The SIMTER tool facilitates concurrent assessment of Ergonomics, Automation Levels and Environmental Impacts. Development work to date has shown that combining these factors is technically feasible and potentially very useful for integrating ergonomics into design processes.

Food intake and fuel deposition in a migratory bird is affected by multiple as well as single-step changes in the magnetic field

- Recent studies have shown that migratory thrush nightingales (Luscinia luscinia) experimentally treated with multiple changes of the magnetic field simulating a journey to their target stopover area in northern Egypt, increased fuel deposition as expected in preparation to cross the Sahara desert. To investigate the significance of food intake on the body mass changes observed, in the work described here we analysed food intake of the nightingales under study in those earlier experiments. Furthermore, to study whether a single change in the magnetic field directly to northern Egypt is sufficient to provide information for fuelling decisions, we performed a new experiment, exposing thrush nightingales trapped in Sweden, directly to a magnetic field of northern Egypt. Our results show that an experimentally induced magnetic field of northern Egypt, close to the barrier crossing, triggers the same response in fuel deposition as experiments with multiple changes of the magnetic field simulating a migratory journey from Sweden to Egypt, suggesting that migratory birds do not require successive changes in field parameters to incorporate magnetic information into their migratory program. Furthermore, irrespective of experimental set up (single or multiple changes of the magnetic field parameters) increase in food intake seems to be the major reason for the observed increase in fuelling rate compared with control birds, suggesting that geomagnetic information might trigger hormonal changes in migratory birds enabling appropriate fuelling behaviour during migration.

Historien, barnen och barndomarna. Vad är problemet? : En vänbok till Bengt Sandin
- 2009
-
Samlingsverk (redaktörskap) (övrigt vetenskapligt/konstnärligt)abstract
- Barndomen som den ter sig i ett bestämt samhälle är aldrig socialt och kulturellt neutral. Den är alltid en konsekvens av kulturella, politiska och sociala krafters samverkan. Barndomen skapas – en del skulle säga konstrueras – av politiska, sociala och kulturella förhållanden, av bestämda historiska förhållanden. Vid sekelskiftet 1900 stod barn och ungdomar i centrum för en livlig offentlig debatt. De sågs som ett påtagligt orosmoment på gator och torg och man klagade över föräldrarnas försummelser. Debatten reser en rad frågor rörande barnens roll i samhället. Var barnen verkligen så vanartade som ofta hävdades, och vad var det för brottslighet man var så räddför? Vilka sociala krafter låg bakom skräckvisionerna av ett samhälle inför sitt sammanbrott? Det är viktigt att de historiska förutsättningarna för engagemanget i barnens villkor klargöres. Sådana studier är viktiga eftersom debatter om barn och ungdomars villkor aktualiseras också i våra dagar. Ofta sker detta med jämförbara termer, begrepp och problemställningar. Vid sekelskiftet fördes diskussionen i termer vi känner igen från dagens Sverige; familjens kris och hemmens otillräcklighet, skolans brister, ungdomens agerande i offentliga miljöer och en ökande kriminalitet. Då som idag aktualiseras behovet av fler institutioner för det uppväxande släktet, familjestöd och rådgivning, samt behovet av skolreformer. Det är därför en central uppgift att klargöra under vilka betingelser och förutsättningar barn uppmärksammas sompolitiska och sociala problem.

Impaired flight ability prior to egg laying : A cost of being a capital breeder

- 1To investigate flight ability in captive Zebra Finches during reproduction we compared change in escape take-off ability and wing load of reproducing females with their mates and non-reproducing females when attacked by a model raptor. 2Initially females had 18% higher wing load than males. Non-reproducing females and females that had started egg-laying flew slower than males. Reproducing females reduced wing load during egg-laying and flew faster when the clutch was completed. Non-breeding females remained on high wing load and flow slower than breeding females that had completed their clutch. 3The increase in flight speed of breeding females was explained by a reduction in wing load during egg-laying. 4Zebra Finches use accumulated reserves to produce eggs and pay a cost in terms of reduced flight ability, but then regain flight performance when the clutch is laid, probably demonstrating a predation cost of capital breeding in birds.

Konferensbidrag (refereegranskat)abstract
- Production development can conflict with productionergonomics and management of environmental impacts. Inthis paper, we describe how ergonomics can be assessed inproduction system design by means of a joint simulationtool. The tool enables ergonomics and environmentalimpacts assessment in conjunction with production processdevelopment. The ergonomics sub-tool is based on adigital human model, which has been improved byintroducing an updated data measurement system andneural network processing and inference functionality. Theresults will extend the new simulation modellingcapabilities of the existing digital human model byincreasing the motion prediction accuracy and providingfreedom to model a multitude of task-related motions in arealistic way.
