Införandet av Computer Based Mathematics (CBM) i ingenjörsutbildningar
- 2017
-
Conference paper (pop. science, debate, etc.)abstract
- CBM är ett koncept som innebär användning av datorn och matematikprogramvaror som huvudverktyg i under-visningen. Istället för att som i traditionell undervisning kombinera handräkning med datorlabbar ligger tyngdpunkten i en CBM-kurs på datoriserade beräkningsverktyg. Härav för-flyttas fokus mot konceptförtåelse, modellering och tolkning av resultat. Vid Högskolan i Halmstad och Karlstads Universitet finns idag flera kurser baserat på CBM. Kvantitativt har införandet lett till ökad studentgenomströmning samtidigt som innehållet i kurser har ökat. Kvalitativa markörer, såsom studentens egen uppfattning om konceptuell förståelse och nyfikenhet inom ämnet, har baserat på kursvärderingar också ökat.

Onsala Space Observatory – IVS Network Station Activities during 2014
- 2015
-
Reports (other academic/artistic)abstract
- We participated in 39 IVS sessions, includ-ing CONT14. Eleven out of the initially planned ses-sions could not be observed due to the installation ofa new radome for the 20-m radio telescope. As in theprevious six years, we used several of the sessions thatinvolved both Onsala and Tsukuba to perform ultra-rapid UT1-UTC sessions together with our colleaguesin Tsukuba. This included the complete CONT14 cam-paign where near real-time UT1-UTC on the baselineOnsala—Tsukuba could be determined. The procure-ment of the telescopes for the Onsala Twin Telescopeswas started in the summer of 2014. The contract to buytwo VGOS radio telescopes was signed at the end of the year.

- In this study, we have used Tanzania as a case to illustrate how a simulation model can beused to evaluate the impact of aid and the trade-offs between public spending categories and theirimpact on income poverty and other social development targets. Our results suggest the following.First, under plausible growth, fiscal and foreign assistance assumptions, in line with observedpatterns, the enormous difficulty of achieving most millennium development goals (MDGs) by2015 is evident. Second, there existed trade-offs between the various MDGs, in particular betweenachievements for poverty and other social development targets.

A first order friction model for lubricated sheet metal forming

Journal article (peer-reviewed)abstract
- This paper presents the derivation of a first order friction model for lubricated sheet metal forming. Assuming purely plastic real contacts, Newton's law of viscosity, and a square root behavior of the hydrodynamic coefficient of friction with respect to the hydrodynamic Hersey parameter an analytic model is found. The model predicts the coefficient of friction as a function of the relative pressure, the relative Hersey parameter and the real contact coefficient of friction. Questions about local and global friction are raised in the validation of the model against flat tool sheet experiments. For some flat tool sheet experiments reasonable agreements are obtained assuming a rigid punch pressure distribution. The restricted number of user inputs makes the model useful in early tool design simulations. © 2018 The Authors.

History, art and shame in von Donnersmarck's the Lives of Others

Journal article (peer-reviewed)abstract
- Commentary on the successful directing and scriptwriting debut of Florian von Donnersmarck, The Lives of Others, tends to divide into those faulting the film for its lack of historical accuracy and those praising its artistry and conciliatory symbolic function after the reunification of the GDR and BRD. This essay argues that even when we grant the film's artistic premise that music can convert the socialist revolutionary into a peaceful liberal, suspending the demand for realism, the politics intrinsic to the film still leads to a problematic conclusion. The stern Stasi officer in charge of the surveillance of a playwright and his actress partner comes to play the part of a selfless savior, while the victimized actress becomes a betrayer. Her shame however, is not shared by the playwright, Dreyman, and the Stasi officer, Wiesler, who never meet eye to eye but instead become linked in a mutual gratitude centering on the book dedicated to Wiesler, written years later when Dreyman learns of the other's having subversively protected him from imprisonment. Despite superb acting and directing, dependence on such tenuous character development makes the harmonious conclusion of the film ring hollow and implies the need for more serious challenges to German reunification. © Moderna språk 2017.

Journal article (peer-reviewed)abstract
- INTRODUCTION: This longitudinal case-controlled study examined the effects of universal parent-focused interventions on parents’ perceived competence in terms of parental efficacy and satisfaction.METHOD: The study sample consisted of parents from northern Sweden in the general population who participated in parent training programmes from 2010 to 2013, and a matched-comparison group. All parents had children aged 0–17. Sense of competence was measured by the Parenting Sense of Competence Scale at pre- and post-intervention and six months after the intervention.RESULTS: The intervention group showed a statistically significant improvement in parental competence compared to the comparison group over time. The intervention itself had a significant effect on parental satisfaction, but the efficacy effect was not sustained when taking into account potential confounders.CONCLUSIONS: Earlier studies indicate that parent training programmes enhance perceived parental competence amongst referred parents. The present study shows that parent training programmes applied in the general population may also enhance perceived parental satisfaction, suggesting that parent training programmes can be an important preventive strategy to enhance parental feelings of satisfaction in the wider population. The results suggest that parents who participate in parent training programmes might have a need to increase parental competence, based on lower scores than the comparison group, both before and after the intervention.

Journal article (peer-reviewed)abstract
- This is a confirmatory study that assessed the effects of parent training programs on parental stress in a general population. There is a need to repeat and confirm earlier findings to acquire solid knowledge for policy stakeholders. In a quasi-experimental design, self-reported data were gathered at three occasions from 83 parents of children between the ages from one to ten years. These parents had responded to advertisements of parent training programs, and were matched to a comparison group of 83 parents chosen from a governmental database. Parent training program based upon behavioral, cognitive-behavioral, Adlerian and family system-theories. Parental stress due to incompetence, role restriction, social isolation, spousal relationship problems, and health problems were measured by the Swedish Parenthood Stress Ques- tionnaire that is based on the Parent Stress Index Scale. The data indicated a reduction of stress in the sub-scale of health problems among parents in the intervention group with an effect size of 0.33, however, no other subscale showed the intervention as a significant variable when controlling for confounding variables. This study adds on the accumulated knowledge of supporting interventions for parents. We conclude that parent training programs have a significant effect on the stress components of parental health when implemented in real-life settings.

Healthier Parents : Effects of Parent Training Programs on Mental Health
- 2017
-
In: International Journal of Social Work and Human Services Practice. - : Horizon Research Publishing Co., Ltd.. - 2332-6832 .- 2332-6840. ; 5:2, s. 70-79
-
Journal article (peer-reviewed)abstract
- The study aims to investigate the effects of Parent Training Programs on the mental health of parents with children aged between 1 and 17 in a universal preventive setting. The intervention group included 279 parents who were assigned to five professionally administered interventions, which included 5–10 two-hour sessions; they were then compared to 702 parents in the comparison group without intervention. The improvement in general mental health was statistically significant in the intervention group compared to the comparison group. The findings suggest that evidence-based parent training programs enhance well-being in parents without indicated problems. However further exploration of preventive training programs for parents are needed.

Preventive psychosocial parental and school programmes in a general population
- 2017

Doctoral thesis (other academic/artistic)abstract
- Introduction Numerous preventive programmes have emerged, and need to be investigated to determine their effects on the normal population. Earlier studies have shown a decrease in depressive symptoms, positive effects on children’s disruptive behaviour problems, and an improvement in parental competence. About a fifth of the parents in previous studies had problem-oriented (targeted) reasons for enrolment, whereas the rest of the parents had general (universal) reasons. The results of those studies suggest that the programmes are cost effective in terms of Quality-Adjusted Life Years.Aim Four sub-studies were performed, and their aims were to investigate the effect of parental training programmes (PTPs) in a naturalistic setting on parents’ mental health in the general population, to investigate how PTPs affect parents’ sense of parental competence, to investigate how PTPs affect parental stress and analyse the parents open questions about the PTPs, and to investigate the feasibility and to measure the effect on depression, anxiety, and social problems of two preventive school programmes for pupils in grade 7.Method In a longitudinal quantitative study in a real-world setting, 279 parents from the general population in northern Sweden participated in five PTPs. A comparison group of 702 parents without intervention was included. Simultaneously, a community sample of 59 pupils in grade 7 participated in two preventive school programmes. Both studies were conducted from 2010 to 2013. Parents were assigned to professionally supported interventions that included 5-10 two-hour sessions. Respondents filled in a web-based questionnaire with the General Health Questionnaire (GHQ), the Parents Sense of Competence (PSOC) for parents who had children aged 0-17 years, and the Swedish Parenthood Stress Questionnaire (SPSQ) for parents who had children aged 0-10 years. The intervention groups’ results were compared to comparison group of 702 parents from northern Sweden that had not participated in any parental training programme. In the school study, one of the preventive programmes was an ongoing programme called “Life-Skills”, and the other was an implemented Canadian programme called “Choosing Healthy Actions and Thoughts” (CHAT). The pupils completed a test battery including the Sense of Coherence (SOC), the Children’s Depression Inventory (CDI), and the Youth Self-Report (YSR) instruments. Follow up of the parental programme study was done six months after the post-intervention measure, and follow up of the school study was at one year.Results The improvements in GHQ were statistically significant for the mean of the 279 parents in the intervention group compared to the mean of a comparison group of the 702 parents who did not receive any intervention. This suggests that evidence-based PTPs enhance parental well-being even for parents without problems. The intervention group showed a statistically significant improvement in parental competence compared to the comparison group over time. The intervention itself had a significant effect on parental satisfaction, but the efficacy effect was not sustained when taking into account potential confounders. In the SPSQ, the intervention group was smaller due to the fact that the instrument was not validated for children over the age of 10 and one of the parental training groups was only for parents of teenagers. A reduction of stress in the sub-scale of health problems was detected, but no other subscale showed the intervention to have a significant effect when controlling for confounding variables. In the school study, both programmes had good feasibility according to the stake- holders and had several positive mental health outcomes over time. Compared to Life-Skills, CHAT had more significant positive effects on reducing anxious/depressive symptoms and girls experienced significant positive effects on reduced anxious/depressive behaviour, while boys reduced their aggressive behaviours.Conclusions Earlier studies indicate that PTPs enhance perceived parental competence among referred parents. The present study shows that PTPs applied in the general population might also enhance perceived parental benefits such as improved health and satisfaction, suggesting that PTPs can be an important preventive strategy to enhance parenthood. The results suggest that parents who feel a need to increase their parenting competence might participate in PTPs based on lower scores than the comparison control group both before and after the intervention. The school-based programme shows that schools may be a suitable arena for preventive programmes because there was a significant short-term improvement in depression symptoms. Further studies need to explore how parents’ participation in PTPs affects children’s mental health in the general population in quantitative longitudinal studies in real-word settings. There is also a need for bigger studies and RCTs on school preventions and on how children’s health develops naturally in the population.
