Konferensbidrag (refereegranskat)abstract
- Purpose: "Where Are All the Women CEOs?" (Fuhrmans, 2020) is a corporate question describing the growing sense of gender diversity and women's discrimination in top leadership positions. Nowadays, gender equality is an important topic and plays a strategically important role in corporations. However, women remain underrepresented and are treated differently than men counterparts in top executive positions. Thus, this research aims to provide insights into the major themes and critically reflect on the literature regarding women/female CEOs of the past two decades.Design/methodology/approach: A Structured Literature Review (SLR) was conducted. All included articles stemmed from the ABS or ABDC journal rankings, resulting in 162 relevant articles. The time frame was 2000 through 2020 (20 years). Databases included in this review were: Scopus (Elsevier), ProQuest, Emerald Insight, JSTOR and ABI/Inform. All results were limited to English-only peer-reviewed scientific journal articles.Findings: The analysed literature on women/female CEOs addresses their personal and professional characteristics (outer appearance and leadership style), their appointment and hierarchical advancement, their effect on different business organizational aspects (such as firm performance and governance), the gender pay gap and the glass ceiling/cliff. Furthermore, the findings suggest that women are underrepresented in CEO positions, face various discrimination statuses, and bear with cultural and ethnic barriers to elevating hierarchy.Research limitations/implications: The coding process, in particular, the code grouping, could be influenced by the researchers’ subjectivity. In addition, not all collected data was analysed, as some codes and data were not considered beneficial for this research. Originality/value: To the best of the authors' knowledge, such research regarding female leadership, namely the CEO position, is limited, and no structured literature review within the AJG/ABDC ranking was found during the data collection phase. Hence, such an effort can serve for future research to dive deeper into the topic of female/women CEOs. The method has been described in detail to ensure transparency and researchers’ reproducibility of the results.

Using symmetry to control viscoelastic waves in pillar arrays
- 2023

Tidskriftsartikel (refereegranskat)abstract
- Solutions of macromolecules exhibit viscoelastic properties and unlike Newtonian fluids, they may break time-reversal symmetry at low Reynolds numbers resulting in elastic turbulence. Furthermore, under some conditions, instead of the chaotic turbulence, the result is large-scale waves in the form of cyclic spatial and temporal concentration variations, as has been shown for macromolecular DNA flowing in microfluidic pillar arrays. We here demonstrate how altering the symmetry of the individual pillars can be used to influence the symmetry of these waves. We control the extent of instabilities in viscoelastic flow by leveraging the effects of the symmetry of the pillars on the waves, demonstrating suppressed viscoelastic fluctuations with relevance for transport and sorting applications, or conversely opening up for enhanced viscoelasticity-mediated mixing. The onset of waves, which changes flow resistance, occurs at different Deborah numbers for flow in different directions through the array of triangular pillars, thus breaking the symmetry of the flow resistance along the device, opening up for using the occurrence of the waves to construct a fluidic diode.

- The mechanism of formation of two different cubic mesoporous silica materials formed with Pluronic triblock copolymers is investigated with in situ time-resolved small-angle synchrotron X-ray scattering, in situ time-resolved H-1 nuclear magnetic resonance, and time-resolved transmission electron microscopy. The materials studied are the micellar cubic (Im (3) over barm) SBA-16 formed with Pluronic F108 and the bicontinuous cubic (Ia (3) over bard) silica material formed with Pluronic P103 and NaI. The formation mechanisms of the two cubic structures are shown to be dissimilar. For the Im (3) over barm material, in the early stages of the synthesis, floes of unordered micelles are observed, but areas where the micelles have started to order are also present. With time, there is an increase in order; however, there is a coexistence of unordered micelles and ordered material all through this study. The bicontinuous cubic silica is formed via a different path. The system is phase-separated already before the addition of the silica source, which implies that a concentrated phase is present, acting as the structure director of the Ia (3) over bard structure. The results are compared with earlier reports on the formation of the hexagonal SBA-15 material.

How Co-Teaching May Contribute to Inclusion in Mathematics Education : A Systematic Literature Review
- 2023
-
Ingår i: Education Sciences. - : MDPI. - 2227-7102. ; 13:7
-
Tidskriftsartikel (refereegranskat)abstract
- This systematic literature review focuses on co-teaching and inclusion in mathematics education. Co-teaching, in which two or more teachers share responsibility for students’ mathematical learning, can cater to students in need of special education. Through a narrative synthesis of 15 articles found through searches in 5 databases, this study investigates what characterizes coteaching and how it contributes to students’ inclusion in mathematics education. The review was conducted by identifying the focus, specifying review questions, determining studies to include, deciding on data to extract, and reporting the results. The findings show that co-teaching can contribute to spatial inclusion in mathematics education, implying that all students can be taught in the same classroom. Furthermore, co-teaching that contributes to social and didactical inclusion addresses all students’ mathematical learning if it is flexibly organized. Therefore, students struggling to gain access to mathematics and those requiring extra challenges in mathematics learning can benefit from this teaching model.

- In response to the increased early workflow implied by BIM processes it is important for design consultants to focus on creating and communicating information that is critical for its purpose (Jernigan 2008) - be it model content for 3d Design Coordination at scheme design stage, or Cost Estimation at Design Development stage, or generation of a suitable Record Model for Facilities Management. Today, with many of the technological matters of integrated information management dealt with (perhaps excluding the matter of interoperability), defining the content and status of BIM information deliveries remains both a practical and theoretical problem. A development of a participant-friendly method of articulating BIM content is required to clarify what information is needed when and conversely what information is indeed not needed to implement a BIM process at a particular stage in a construction project. Priority must be placed on the information that is vital for current tasks without getting distracted by desires to populate models with additional or other information or objects masking the absence of key information. Here there is a lack of existing knowledge to solve this practical problem. New BIM tools and new design processes and procedures have led to a certain confusion of what information is needed when for particular BIM uses. This report seeks to explore and enable a method of defining the content of model information deliverables through a review of 2 key primary specific BIM uses: 3d Design Coordination and Early Energy Appraisal through an analysis of practical application. The scope of this study is limited to a review of information flow within residential projects in a Swedish context and looks at two case projects with a view to identifying and establishing a common definition of the key BIM objects and properties necessary for particular tasks. The study follows a case construction project together with an experimental pilot design project with the purpose of extracting and recording what data is needed to carry out parallel and sequential BIM uses with optimised efficiency. By mapping both processes and the precise information needed to successfully carry out tasks, improved productivity can be realised and a greater quality of design output produced. The key deliverable from this study is the BIM-Info Delivery Protocol (IDP) which attempts to align consultant BIM-Info delivery expectations and represents a tangible solution to assist consultant disciplines manage BIM-Info

Can Co-Creation and Crowdfunding Types Predict Funder Behavior? : An Extended Model of Goal-Directed Behavior
- 2019

Ingår i: Sustainability. - : MDPI. - 2071-1050. ; 11:24, s. 1-23

Tidskriftsartikel (refereegranskat)abstract
- Crowdfunding is an emerging means for financing by small and medium-sized enterprises or individuals to attract capital from investors who look to obtain products, services, and/or equity in the future. Co-creation in crowdfunding projects substantially influences sponsors' behavior, playing a critical role in crowdfunding performance. Despite the significance of co-creation in crowdfunding, research from the leisure and tourism fields has been largely neglected in terms of theory-based models of co-creation. To address this gap, the goal of this work is to study the effects of co-creation on the extended model of goal-directed behavior, along with the moderator of crowdfunding types. To do this, an online survey was conducted on crowdfunders in South Korea and partial least squares (PLS)-structural equation modeling (SEM) was applied to analyze the collected data. Results reveal that co-creation considerably leads to attitude towards, as well as behavior in relation to, crowdfunding participation. Funders' attitude and positive and negative anticipated emotion also significantly influence desire to participate in crowdfunding. Behavioral intention is highly affected by perceived behavioral control as well as desire. Reward and investment types significantly moderate eight relationships in the research model. Hence, this study contributes to crowdfunding research and stakeholders in the visitor economy sectors.

Distinct expression ofgelatinase A (MMP-2), collagenase-3 (MMP-13), membrane-type MMP 1 (MT1-MMP), and tissue inhibitor of MMPs type 1 (TIMP-1) mediated by physiological signals during formation and regression of the rat corpus luteum

- The corpus luteum (CL) is a transient endocrine organ that secretes progesterone to support pregnancy. The CL is formed from an ovulated follicle in a process that involves extensive angiogenesis and tissue remodeling. If fertilization does not occur or implantation is unsuccessful, the CL will undergo regression, which involves extensive tissue degradation. Extracellular proteases, such as serine proteases and matrix metalloproteinases (MMPs), are thought to play important roles in both the formation and regression of the CL. In this study, we have examined the physiological regulation pattern and cellular distribution of messenger RNAs coding for gelatinase A (MMP-2), collagenase-3 (MMP-13), membrane type MMP 1 (MT1-MMP, MMP-14), and the major MMP inhibitor, tissue inhibitor of MMPs type 1 (TIMP-1) in the CL of adult pseudopregnant (psp) rat. Northern blot and in situ hybridization analyses revealed that gelatinase A messenger RNA was mainly expressed during luteal development, indicating that gelatinase A may be associated with the neovascularization and tissue remodeling that takes place during CL formation. Collagenase-3 had a separate expression pattern and was only expressed in the regressing CL, suggesting that this MMP may be related with luteal regression. MT1-MMP that in vitro can activate progelatinase A and procollagenase-3 was constitutively expressed during the formation, function, and regression of the CL and may therefore be involved in the activation of these MMPs. TIMP-1 was induced during both the formation and regression of the CL, suggesting that this inhibitor modulates MMP activity during these processes. To test whether the induction of collagenase-3 and TIMP-1 is coupled with luteal regression, we prolonged the luteal phase by performing hysterectomies, and induced premature luteal regression by treating the pseudopregnant rats with a PGF2alpha analog, cloprostenol. In both treatments, collagenase-3 and TIMP-1 were induced only after the serum level of progesterone had decreased, suggesting that collagenase-3 and TIMP-1 are induced by physiological signals, which initiate functional luteolysis to play a role in tissue degradation during structural luteolysis. In conclusion, our data suggest that gelatinase A, collagenase-3, and MT1-MMP may have separate functions during the CL life span: gelatinase A mainly takes part in CL formation, whereas collagenase-3 mainly takes part in luteal regression; MT1-MMP is constitutively expressed during the CL life span and may therefore serve as an in vivo activator of both gelatinase A and collagenase-3. TIMP-1 is up-regulated both during the formation and regression of the CL and may therefore regulate MMP activity during both processes.
