  • Market Segmentation in Scientific Publications : Research Patterns in American vs European Management Journals
  • 1996
  • Ingår i: British Journal of Management. - Chichester : Wiley-Blackwell. - 1045-3172 .- 1467-8551. ; 7:2, s. 141-154

    • <p>Ideal science should conform to certain criteria or goals, among them the goals of universalism and commonality. Realization of these goals may be limited, however, through the dividing up of researchers in terms of geographical borders. In this study the general hypothesis is tested that there is a segmentation of the society of management researchers into a North American (US) and a European (E) segment, a segmentation which is furthered by differences in incentive schemes and in paradigms. Four leading management journals from North America and from Europe, respectively, and the 242 articles they contained published in 1993 were selected to represent the different geographical segments. The results provide: support for the existence of two such segments; support for differences in incentive schemes influencing the articles; support for their being paradigm differences between the two segments; and support for a paradigm effect being stronger in US-journals than in E-journals, US-authors are more willing, however, to conform to the E-paradigm than vice versa. We argue for methodological pragmatism in order to reduce the presumed counter-productive effects of paradigmatic rigidity.</p>

  • Den nya rödlistan har 746 svampar
  • 2010
  • Ingår i: Svensk mykologisk tidskrift. - Sveriges Mykologiska Förening. - 1653-0357. ; 31:2, s. 37-47
  • Tidskriftsartikel (refereegranskat)abstract
    • The new Red List that was recently presented by the Swedish Species Information Centre (Gärdenfors 2010) includes 746 species of fungi considered to be threatened. Compared to the previous Red List published in 2005, 36 species have been down-listed whereas 150 species have been added, thus the list has increased by 114. The changes are above all due to increased knowledge of taxonomy, ecology and distribution. In the present paper members of the Species Specialist Group for Fungi 2006-2010 summarize the background and results of the red-listing process and present the habitats in which the red-listed species occur.

  • Kommunikation i förskolan förskollärares och barnskötares kommunikation med föräldrar i ett digitaliserat medielandskap
  • 2019
  • Doktorsavhandling (övrigt vetenskapligt)abstract
    • <p>The overall aim of this doctoral thesis is to study communication work among personnel in Swedish pre-schools, with a particular focus on mediated communication with parents. The purpose is also to analyse what roles are given to the professionals in this communication, to identify what subject positions are constructed and to identify how boundaries are managed within the communication practices.</p><p>The primary theoretical framework of the thesis is social constructivism and symbolic interactionism. The pre-school organisation and identities are regarded as in a perpetual state of becoming and changes in the media landscape are viewed as rearranging the preconditions for communication practices. Technical innovations are regarded as social products at both ends. Results build upon observations in five pre-schools, interviews with 32 pre-school employees and multimodal analysis of communication material directed to parents. Additional interviews and document studies were conducted in the form of a case study, in order to gain knowledge of the implementation of a digital learning platform.</p><p>The study shows that the communication environments differ between pre-schools, e.g. concerning how and which mediums are used. Several obstacles to communication are identified, of which many (but not all) are related to the socioeconomic status of parents. Within the mediated communication, pre-school personnel to some extent position themselves as experts concerning practical and pedagogical questions, whilst parents are positioned as actors in need of guidance. A major function of mediated communication is assigning parents’ responsibilities in relation to the pre-school, along with norms regarding what constitutes the “good” (pre-school) parent. Boundary work in relation to parents is conducted using different modalities, used for hedging but also for establishing professional positions. Digitalisation appears as a negative force when introduced top-down, without regards to the needs, previous practices and preconditions within a particular pre- school; but as a positive force when initiated by the professionals themselves and when responding to particular needs within specific pre-schools. As expectations on digitalisation in pre-schools increase, questions of preconditions and communication skills grow in prominence.</p><p>Although expectations on pre-school professionals’ communication skills are high, communication with parents is not sufficiently acknowledged as part of the actual work in pre-schools. A sign of (and reasons for) the under prioritisation of communication work is the uneven and arbitrary preconditions for communicating, in the forms of relevant education, time and technical equipment. The lack of resources can be connected to three issues: A working environment issue (discrepancy between expectations and preconditions), a democratic issue (communication being random rather than planned/ considered) and a professional issue (multimodal communication not reflecting the professional identity that informants strive towards).</p><p>Communication with parents (and surrounding society) needs to be acknowledged as part of the work in pre-school, and the personnel need to be given the necessary skills and conditions for communication, in order to provide equality of ac- cess to the parents, but also to give personnel the possibilities of communicating about and reflecting the pre-school organisation as they know it.</p>

  • Radioembolization Versus Bland Embolization for Hepatic Metastases from Small Intestinal Neuroendocrine Tumors: Short-Term Results of a Randomized Clinical Trial.
  • 2018
  • Ingår i: World Journal of Surgery. - 0364-2313 .- 1432-2323. ; 42:2, s. 506-513
  • Tidskriftsartikel (refereegranskat)abstract
    • Radioembolization (RE) with intra-arterial administration of 90Y microspheres is a promising technique for the treatment of liver metastases from small intestinal neuroendocrine tumors (SI-NET) not amenable to surgery or local ablation. However, studies comparing RE to other loco-regional therapies are lacking. The aim of this randomized study was to compare the therapeutic response and safety after RE and bland hepatic arterial embolization (HAE), and to investigate early therapy-induced changes with diffusion-weighted MRI (DWI-MRI).Eleven patients were included in a prospective randomized controlled pilot study, six assigned to RE and five to HAE. Response according to RECIST 1.1 using MRI or CT at 3 and 6 months post-treatment was recorded as well as changes in DWI-MRI parameters after 1 month. Data on biochemical tumor response, toxicity, and side effects were also collected.Three months after treatment, all patients in the HAE group showed partial response according to RECIST while none in the RE group did (p = 0.0022). After 6 months, the response rates were 4/5 (80%) and 2/6 (33%) in the HAE and RE groups, respectively (NS). DWI-MRI metrics could not predict RECIST response, but lower pretreatment ADC(120-800) and larger ADC(0-800) increase at 1 month were related to larger decrease in tumor diameter when all tumors were counted.HAE resulted in significantly higher RECIST response after 3 months, but no difference compared to RE remained after 6 months. These preliminary findings indicate that HAE remains a safe option for the treatment of liver metastases from SI-NET, and further studies are needed to establish the role of RE and the predictive value of MR-DWI.

  • SAMLIC pilotförsöket
  • 2006
  • Rapport (övrigt vetenskapligt)abstract
    • <p>Growing cities are increasing the demand for goods carrying traffic to function well with other traffic. The number of zones for unloading goods in the centre of Linköping is small compared to the number of delivery addresses and the number of goods distributors. The attendant phenomena are congestion and costs of congestion. Therefore the local network for freight forwarders in Linköping has taken the initiative to the SAMLIC project. SAMLIC stands for Coordinated Retail Distribution in Linköping City. The aim of SAMLIC is to create an economically and logistically efficient system for goods distribution that is persistent and friendly to the environment. Economic profitability is neccessary for a system with a joint venture in coordinated distribution. The savings with coordinated distribution for the freight forwarders must be of such a dimension that they find it profitable to join instead of delivering the goods by themselves. During a trial period of nine weeks in the spring of 2004 there was a coordinated distribution to the centre of Linköping. Three freight forwarders took part in this project. The experience of the trial shows that the needed number of trucks decreased by 33 %, the total time for the distribution decreased by 15-20 % and the total driving kilometers in the centre decreased by at least 50 %.</p>

  • A Novel Sensor for Bite Force Determinations
  • 2003
  • Ingår i: Dental Materials. - 0109-5641 .- 1879-0097. ; 19:2, s. 118-126
  • Tidskriftsartikel (övrigt vetenskapligt)abstract
    • <p>OBJECTIVES: The clinical usefulness, accuracy and precision of a novel bite force sensor based on force sensing resistors were tested in six subjects wearing maxillary removable partial dentures retained by conical crowns. METHODS: The surfaces of the sensor were manufactured in a silicone material that had mechanical properties similar to those of tough foodstuffs. In two separate series of standardized bite force tests, submaximum force levels were recorded with the sensor and with a strain gaged bite fork. Subjects were assisted in the loading tests with visual feedback instrumentation. Reliability estimates for the bite force sensor were calculated in order to show their reproducibility. Strain gages attached to the prostheses were used to determine the pattern of force distribution during loading tests. The bite force results obtained with the new bite force sensor and with the bite fork were analyzed with ANOVA and Scheffes tests. The strain patterns registered with strain gages were analyzed with F-test. RE-SULTS: The bite force sensor and the bite fork transducer showed no statistically significant differences in respect of intra-individual bite force levels (range 50-300N). The bite forces registered with the new sensor were dependent on the loading position (p<0.05), sex (p<0.05) and test subject (p<0.05). The reliability of the new sensor for sub-maximum bite forces was calculated to be 93%. Strain gage results showed that the new sensor generated strain patterns of less variance (p<0.05) than the bite fork and therefore allowed for higher precision during biting tests. SIGNIFICANCE: The presented instrument has such clinical merits, as to favor its use in experimental clinical studies on the biomechanics of prosthetic appliances.</p>
