  • Alternatives To Supervised Placements : Work Integrated Education In Action: editorial board
  • 2023
  • Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
    • When work integrated education (WIE) is discussed, the archetypal examples of supervised placements for medical, nursing, physiotherapy, and teacher education students are usually referenced. They comprise students engaging in authentic work activities and interactions, closely supervised by qualified and more experienced practitioners. Ideally, those supervisors identify and select students’ work activities and support and guide their engagement and learning. These arrangements often arise from long-standing occupational traditions of care and responsibility towards patients and students and have legislated arrangements demanding such supervision.However, for many occupations such traditions do not exist and, where they exist, placements are less structured. Moreover, the ability to provide placements are restricted by the size of the enterprise, the work undertaken and/or the number of students seeking these experiences. One deputy vice chancellor quipped “how can I provide supervised placements for 1500 undergraduate business students each semester?”. A good question.So, in seeking to provide WIE experiences across all occupational fields, it is not possible for many of the courses in which our students are enrolled. The educational challenge is, therefore, to identify how these students can come to experience, engage, and develop occupational understandings, procedures and dispositions (i.e., to think and act like practitioners). Hence, we need to find alternatives to provide these experiences. In the response to the quip above, it was suggested, for instance, that most undergraduate students engage in paid part-time work that provide experiences to assist understand many aspects of business practices. That is, processes of recruitment, supervision, customer interaction, stock provisions and organisation, financial processes and supervision. Engaging students in sharing, comparing and critiquing these work experiences, can secure insights from peers’ experiences and provide access to students who do not work part-time.Such alternatives might include students being workplace visitors able to observe and engage in some tasks, or interviewing practitioners to understand what constitutes their work, and is central to its enactment. Law students might attend court proceedings to understand those processes, finance students engaging in auditing of not-for-profit organisations’ accounts, or projects required the kinds of thinking and acting of practitioners. This kind of approach has been long rehearsed within faculties of engineering, creative arts etc. So, we can identify and use these kinds of experiences. But what if the students are dispersed around the world? The web based “Webmaster” program at University West faced this problem. Moreover, these students are in different stages of life, often having to balance work, family and study commitments. We have found that providing these students with glimpses of work practices offers an alternative to workplace visits.Moreover, the field of “web” is marked by openness and sharing, and videos on, for example, YouTube providing insights into workplace activities are abundant. A search for “A day in the life of an UX designer”, for instance, generates hundreds of video suggestions and in courses relating to that topic, students are provided with a list to view and then engage in discussions about them. Through using these kinds of materials, students gain insights into different work practices. Other alternatives have included engaging business representatives as guest lecturers, but with our students located across time zones this can be an option that is time-restricted. A “flipped” guest lecture or workshop is provided to campus-based students, and “re-enacted” by students in the Webmaster program, supervised by teachers.Moreover, as occupational practices are increasingly mediated by and through electronic technology, the need to engage in the physical and social environment of workplaces becomes less important. Alternatives not requiring physical presence in work sites can ease the demand on employers. The key consideration is, instead, for students to gaining access to and engage in the kinds of thinking and acting required for electronically-mediated work activities and interactions. In such contexts, supervised placements are not feasible and less applicable as an effective WIE approach, because future work environments are not necessarily place-based.The challenge we face includes preparing students for diverse work contexts. Remote work, nomadic work practices and gig-based work are becoming common, and these may or may not represent possible future work contexts for our students. We also aim to explore different forms of “one-to-many” engagements (Dean & Campbell, 2020), where, for example, enterprises can provide video-challenges, i.e., examples of problems they are currently facing, and engage groups of students in seeking to respond to these problems, while being supervised by teachers.Such short bursts of intense and focused WIE would benefit both our students and partner enterprises and serve to strengthen student employability.

  • Enhanced CD56 expression and increased numbers of CD56+bright cells in the peripheral blood of untreated endometriosis patients
  • Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
    • Problem: Endometriosis is characterized by ectopic implantation of endometrial-like tissue and impaired immuneresponses such as the cytotoxic function of NK cells. NK cells can be divided into two subpopulations where theCD56+bright cells produce more cytokines and have low natural cytotoxicity compared to CD56+dim cells. Themajority (>90%) of circulating NK cells are CD56+dim whereas very few (0-10 %) are CD56+bright.Method of Study: Using flow cytometry, NK cell subpopulations were analyzed in peripheral blood from 21individuals with endometriosis and 12 healthy controls. Furthermore, the NKG2D receptor expression on PBMCswas analyzed in untreated and treated endometriosis patients and controls.Results: We found an increased level of CD56+bright cells in 8 of 21 endometriosis patients. After surgery andhormonal treatment, the levels were normalized to that of controls. In a new cohort, the NKG2D receptorexpression on PBMCs was analyzed, with a lower expression in untreated patients compared to controls andpatients treated by surgery and hormones.Conclusions: Our findings of a dominant CD56+bright NK cell subpopulation in peripheral blood, anddownregulated levels of the NKG2D receptor on PBMCs, may explain the impaired cytotoxic immune functioncausing the persistence of ectopic endometrium in untreated endometriosis patients.

  • Dynamic hollow-fibre liquid phase microextraction for human plasma samples automated by sequential injection analysis
  • Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
    • This paper presents an easily handled, hollow-fibre liquid phase microextraction (HF-LPME) sample clean-up method, automated by the use of a programmable sequential injection analysis (SIA) system. Use of a SIA system significantly reduces the need for manual sample handling. This new type of clean-up system was assessed and compared with manual HF-LPME for the extraction of acidic compounds (dinitrophenols) from human plasma, in terms of human intervention requirements, efficiency, repeatability and carry-over. Its application to a SIA system for basic compounds (b-blockers) is also presented. The sample aliquots collected off-line from the SIA system were subsequently subjected to separation with LC and the various analytes were detected with ESI-MS. Extraction efficiency values between 28 and 56% (RSD 5-10%, n = 7) were achieved for the dinitrophenol compounds after an extraction cycle of 58 min including a 30 min washing step. According to the MS analysis the SIA/HF-LPME method yielded clean chromatograms with no detectable interfering peaks. Ion suppression in positive ESI-MS was between 4 and 21% when tested on extracts with b-blockers.

  • Forest edge density in a gradient of boreal landscapes in Sweden
  • Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
    • The boreal forests in Fennoscandia are strongly fragmented by intensive forestry and other land use resulting in high amount of edge habitat. Detailed data on edge quantity is critical to assess fragmentation effects on biodiversity. We estimated the density of sharp forest edges in 28 landscapes, each 4 km × 4 km, along a 830 km gradient in northern Sweden. Data was collected from colour infrared aerial photographs using line intersect sampling and 20-m radius plots. Forest edge density was 54 ± 4.6 m ha-1 land area (mean ± SE) but variation was high among landscapes (12-102 m ha-1). Natural edges constituted 38% but created edges dominated (36% maintained and 26% regenerating). Thirty percent of edges adjoined narrow (5-19 m) open landscape elements (corridor edges) and seventy percent adjoined more exposed patches (≥20 m, patch edges). We found 34 types of patch edges, with the highest density recorded for edges in mature forest. Edge density increased with proportion of landscape disturbed by forestry and agriculture, and decreased with latitude and altitude, but natural and created edges showed contrasting patterns. The high density of sharp edges and the variability among landscapes implies that edges may have strong and diverse effects on the structure, function and biodiversity of boreal forest ecosystems. This variability must be taken into account when formulating strategies for sustainable forest management.
