Improved Planning Capability for Increased Delivery Precision and Reduced Capital Tie-Up – A Case Study in the Automotive Industry
No full textTillverkande företag står idag inför komplexa utmaningar till följd av globalisering, digitalisering och ökade hållbarhetskrav, vilket gör effektiva produktions- och logistikprocesser avgörande. Två centrala prestationsfaktorer är leveransprecision och kapitalbindning. En intern undersökning hos det studerade företaget identifierade betydande förbättringspotential inom produktionsplaneringen. Historiska data visade en försämring av både leveransprecision och kapitalbindning, huvudsakligen till följd av brister i planeringsförmågan. Syftet med denna studie var att stärka Företagets interna planeringsprocess samt att identifiera och hantera externa faktorer som påverkar leveransprecision och kapitalbindning. Studien har genomförts med stöd av Double Diamond-metodiken, vilken omfattar faserna Discover, Define, Develop och Deliver. Metoder som tillämpades inkluderar litteraturstudier, dokumentanalyser, intervjuer och observationer för att kartlägga nuläget. Rotorsaksanalys med hjälp av Ishikawa-diagram användes för att definiera och prioritera identifierade problem. Studien fokuserade särskilt på produktionsflöde X samt kapitalbindningen i lagerförda fordon före produktion, vilket utgjorde 34,1 procent av den totala kapitalbindningen. Centrala problem som identifierades inkluderade planering för 100 procent kapacitet trots lägre faktisk kapacitet, ineffektiv arbetsfördelning på grund av bristfällig informationshantering, produktionsstopp vid personalfrånvaro, inkonsekventa leveranser från Koncernbolaget samt otillförlitliga data från ett besvärligt stämplingssystem. Analysen visade att planeringsprocessens mognadsgrad begränsas av bristen på dokumenterade rutiner och standardiserade arbetssätt, vilket gör den personberoende. Selekterade förbättringsförslag, att planera för 93 procent kapacitet, använda en datadriven produktionsplaneringsmodell, införa en montör utanför kapacitet, genomföra kontinuerlig analys av leveransdata från Koncernbolaget samt kombinera kulturella och tekniska förbättringar av stämplingssystemet, togs fram och dess effekt bedömdes i samverkan med nyckelpersoner inom Företaget. Förbättringsförslagen bedöms kunna öka Företagets leveransprecision med 58 procent och minska kapitalbindningen med 10 procent.Manufacturing companies today face complex challenges driven by globalization, digitalization, and sustainability demands, making efficient production and logistics processes essential for competitiveness. Two key performance factors are delivery precision and capital tie-up. An internal investigation at the case company revealed significant potential for improvement in production planning, with historical data showing a decline in both delivery precision and capital efficiency, largely due to deficiencies in planning capabilities. This thesis aimed to enhance the company's internal planning processes and address external influences affecting delivery precision and capital tie-up. The Double Diamond methodology guided the research through the phases of Discover, Define, Develop, and Deliver. Methods included literature review, document analysis, interviews, and observations to assess the current state. Root cause analysis, via Ishikawa diagram, were used to define and prioritize key issues. The study focused on the production flow X and pre-production inventory, which accounted for 34.1 percent of total capital binding. Key issues identified included planning based on 100 percent theoretical capacity despite lower actual performance, inefficient work distribution due to poor information flow, production disruptions during staff absences, inconsistent supply from an affiliated company, and unreliable data from a problematic time registration system. The planning process was found to lack standardized routines, making it overly dependent on individual experience. Improvement proposals, such as planning based on 93 percent capacity, implementing a data-driven production planning model, assigning an assembler outside of capacity, continuously analyzing the parent company´s delivery performance, and implementing both cultural and technical changes to the time registration system, were collaboratively selected and evaluated. These changes are estimated to improve the company´s delivery precision by 58 percent and reduce capital tie-up by 10 percent
Hemma mellan världar : En kvalitativ studie om tillhörighet och upplevelser av mellanförskap
No full textIn an increasingly multicultural Sweden, many children grow up with parents from different cultural backgrounds. Previous research suggests that this may lead to ambiguity and identity-related stress, which may limit the individual’s ability to navigate between cultural norm systems. Other studies, however, highlight a form of bicultural competence, described as a resource for social adaptation. This study aims to explore how individuals with one Swedish parent and one parent from another cultural background experience in-betweenness at the intersection of two distinct norm systems. Seven participants were interviewed using semi-structured interviews, and their narratives were analysed qualitatively using theories of habitus, capital, and the third space. The results show that in-betweenness is shaped through the interplay between social norms, identity negotiation, and the individual’s degree of awareness, factors that together influence the sense of belonging and identity.I ett alltmer mångkulturellt Sverige växer många barn upp med föräldrar från olika kulturella bakgrunder. Tidigare forskning visar att detta kan leda till tvetydighet och identitetsstress, vilket i sin tur kan begränsa individens möjlighet att kunna navigera mellan normsystem. Andra studier lyfter däremot fram en form av bikulturell kompetens, vilket beskrivs som en resurs för social anpassning. Denna studie syftar till att belysa hur individer med en svensk förälder och en förälder med annan kulturell bakgrund upplever mellanförskap i skärningspunkten mellan två skilda normsystem. Sju deltagare har intervjuats genom semistrukturerade intervjuer, och deras berättelser har analyserats kvalitativt med utgångspunkt i teorier om habitus, kapital och det tredje rummet. Resultaten visar att mellanförskapet formas i samspelet mellan sociala normer, identitetsförhandlingar och individens grad av medvetenhet, faktorer som sammantaget påverkar hur tillhörighet och identitet upplevs

No full textLeading guideline implementation : from the view of first-line nursing and rehabilitation managers in orthopaedic healthcare
No full textBackground Annually, many persons undergo hip surgery, where urinary retention (UR) is a common complication. A gap exists between clinical practice guidelines (CPGs) and performed care regarding the prevention of UR, highlighting the need for implementation interventions to support uptake of the CPGs. As implementation leaders, first-line managers (FLMs) are key to bridging the knowledge-practice gap and could be included in implementation strategies. Aim To explore guideline implementation in orthopaedic healthcare with a focus on first-line managers’ implementation leadership. Method A cluster-randomised hybrid effectiveness/implementation study involving 17 orthopaedic units performing hip surgery at hospitals located in Sweden. Intervention units formed multi-professional internal facilitating (IF) teams (each including at least one FLM) for a 12-month education and support programme to implement bladder monitoring CPGs. Data was collected via interviews (study I, II, IV), medical record reviews (study III), patient surveys (study III), and registry data (study III), and it was analysed using qualitative content analysis (study I) and thematic analysis (study II), statistical analysis (study III), and realist evaluation (study IV). Results FLMs viewed guideline implementation as a balancing act between organisational structures and unit-level realities (study I). They adapted leadership strategies based on context, often translating guidelines to fit local conditions (study I,II). During COVID-19, implementation was smoother due to unified goals, but it faced barriers such as unclear evidence and rapid changes (study II). The intervention deepened participants’ understanding of both clinical guidelines and implementation science (study IV), though without any statistically significant differences in adherence to bladder monitoring CPGs between intervention and control (study III). Managers played a crucial role in anchoring decisions but stepped back to empower teams (study IV). Conclusion Although FLMs have a clear vision of beneficial leadership in relation to change and use implementation leadership behaviours in CPG implementation, a support and education programme regarding implementation processes could build on their prior knowledge. Still, leadership actions can be influenced by contextual factors, and the FLMs sometimes have to adjust accordingly. Health organisations could support first-line managers in their important role in reinforcing an evidence-based practice by scrutinising the organisational context and creating processes that support implementation leadership

No full textInquiry-based Collaborations for Mathematics Teaching Improvement : Reframing Division of Labor, Rules, and Mediating Artifacts
No full textThis dissertation examines professionals’ Inquiry-based Collaborations for Mathematics Teaching Improvement (ICMTI) through a Cultural Historical Activity Theory (CHAT) framework. While teacher collaboration has a long history, recent research highlights the importance of systematic, inquiry-driven practices that foster critical reflection and the use of data to improve teaching. However, establishing such collaborations poses challenges for professionals, both in terms of organization and the methods and artifacts used for inquiry. The study aims to advance understanding of ICMTI and its processes by investigating how such collaborations may be organized, the challenges encountered, how these challenges may be navigated, as well as the artifacts that mediate collaborative processes and their consequences. To achieve this, the dissertation is grounded in three studies: a systematic literature review, an interview study, and an observational case study, all of which are analyzed using different CHAT-based frameworks. The dissertation deepens the understanding of ICMTI as a complex process, highlighting and nuancing the importance of reflecting on the division of labor, prevailing norms, and the use of artifacts, both in planning and throughout the implementation of ICMTI. This dissertation offers practical insights for designing and implementing future ICMTI and contributes theoretically to the concepts of ICMTI, multi-mediating, and boundary-negotiating artifacts
Unpacking qualitative data in organizational trust research : An application to community appraisal of COVID-19 management in Scandinavia
No full textPurpose: Organizational trust is often professed to be communication-based, yet organizational research rarely provides methodological frameworks exploring how orientations to trust are articulated in communication. This paper therefore aims to help unpack how positions on trust are articulated in qualitative, conversational data in away that can be useful for future qualitative research into organizational trust. Design/methodology/approach: The study contributes methodologically by introducing an untapped resource, appraisal analysis, and applying it to focus groups evaluating the pandemic response in Scandinavia. Findings: The analysis suggests that the emphasis of previous research on rational justifications of trust, commonly via assessments of ability, integrity and benevolence, leaves unexplored stances on trust that are taken more straightforwardly with potential effects on power relations. The study draws attention to suchalternative ways of realizing trust/distrust, with the concepts of simple-assertive evaluation and prescriptive evaluation, which still empower (or oppose) organizations and leaders. In addition, the study disentangles some of the “messiness” of qualitative data by demonstrating how stances on organizational trust involve activity-, agent-, and results-centered evaluations, as well as mixed evaluations. Originality/value: Through the suggested analytical framework, common challenges with qualitative data, involving ambiguities regarding power, agency and overall dilemma-ridden situations, can be dealt with better. It thereby offers methodological fine-tuning that enables a more exhaustive analysis of trust as acommunication-based process.

AI Research Agents for Machine Learning : Search, Exploration, and Generalization in MLE-bench
No full textAI research agents are demonstrating great potential to accelerate scientific progress by automating the design, implementation, and training of machine learning models. We focus on methods for improving agents' performance on MLE-bench, a challenging benchmark where agents compete in Kaggle competitions to solve real-world machine learning problems. We formalize AI research agents as search policies that navigate a space of candidate solutions, iteratively modifying them using operators. By designing and systematically varying different operator sets and search policies (Greedy, MCTS, Evolutionary), we show that their interplay is critical for achieving high performance. Our best pairing of search strategy and operator set achieves a state-of-the-art result on MLE-bench lite, increasing the success rate of achieving a Kaggle medal from 39.6% to 47.7%. Our investigation underscores the importance of jointly considering the search strategy, operator design, and evaluation methodology in advancing automated machine learning.NeurIPS 2025 spotlight</p
Masculine-coded ideals of consuming vegan food : An analysis of Swedish male students’ negotiations of plant-based school meals
No full textWhile a rich body of research links veganism and animal consumption with masculinity, empirical studies connecting masculinity and animal consumption with sustainability are much more limited. To emphasize the environmental consequences of consuming animal products, this study examines upper-secondary male students’ responses to their school’s decision to serve vegan food exclusively. Informed by the concept of vegan ecofeminism and previous research, three main arguments for eating plant-based food have been used to analyze male students’ responses to vegan school food: (1) the contribution to global sustainable development, 2) concern for animal welfare, and (3) improvement of one’s health. In contrast to previous research showing a connection between climate change skeptic opinions and young (often conservative) men, the participants of this study did not express any opinions that could be considered examples of climate change denialism. Instead, the male students’ ideas about their own well-trained and muscular bodies caused resistance to vegan school food
