Objective: This paper analyzes some of the problems with error counting as well as the difficulty of proposing viable alternatives. Background: Counting and tabulating negatives (e.g., errors) are currently popular ways to measure and help improve safety in a variety of domains. They uphold an illusion of rationality and control but may offer neither real insight nor productive routes for improvin
Popular Abstract in Swedish Behandlingsideologier och arbetsmodeller avlöser varandra snabbt i dagens samhälle. Att hänga med i det nya och samtidigt försvara det arbete som man gör eller tidigare gjort är en problematik som allt fler ställs inför. I spelet mellan olika inriktningar byggs det upp en argumentation. I denna avhandling analyseras hur anställda vid en psykiatrisk vårdinstitution, specTreatment ideologies and working models replace each other quickly in today's society. During the 1980s a dramatic dismantling of the psychiatric institutions occurred. The health care system was supposed to be transferred to non-institutional care. This was, however, not possible for all groups of patients. At an institution, specialized in so called demanding patients and patients who received c
Product concentrations may be estimated from gas analysis or calorimetric measurements. These techniques of analysis are fast, simple, and provide a continuous output. To check the accuracy of these estimations, the anaerobic ethanol formation of an industrial strain of the yeast Saccharomyces cerevisiae was selected as a test system. Cultivations were carried out as batch cultures with different
In a breast cancer series (n = 54), preoperative fine needle aspiration (FNA) was compared with biopsy at primary surgery as a source of material for the determination of progesterone receptor (PgR) content by enzyme immuno assay. The respective results manifested a strong correlation (r(s) = 0.82). The fact that PgR content was usually higher in FNA samples than in the corresponding biopsy sample
The distribution of human papillomavirus (HPV) types in cervical cancers is essential for design and evaluation of HPV type-specific vaccines. To follow up on a previous report that HPV types 35 and 58 were the dominant HPV types in cervical neoplasia in Mozambique, the HPV types in a consecutive case series of 74 invasive cervical cancers in Mozambique were determined. The most common worldwide m
Popular Abstract in Swedish Vår konsumtion av varor ger nytta på ett flertal sätt. Men samma varor ger också upphov till olika former av miljöpåverkan genom hela deras livscykel (från råvaruutvinning till slutligt omhändertagande). Vi vet erfarenhetsmässigt att det är bättre att förebygga ett problem än att reparera skadan efteråt och på samma sätt förhåller det sig med miljöproblemen. När det gälPolicies based upon Extended Producer Responsibility (EPR) aim to reduce the environmental impacts of products across their entire life cycle. The intent is to induce design changes in products and thus reduce impacts at source. This, by provision of incentives to producers through an extension of responsibility. Since the early 1990s, a number of countries have incorporated the concept of EPR int
The synthesis of two rigid polycyclic secondary diamines, bis-(2,3:6,7-iminodimethylene)anthraceneand bis-(2,3:6,7-iminodimethylene)-9,10-dicarboxyethenoanthracene,by means of Diels-Alder reaction between 1,2,4,5-tetra(dibromo?methyl)benzeneand maleimides followed by imide reduction, is described. Furthermore,these two cyclic secondary diamines undergo acylation with N-protectedamino acids, thus p
In this paper, I propose a relevance-theoretic account of the particles le, guo and zhe in Mandarin Chinese. Though conventionally regarded as aspect markers, on closer inspection they seem to contribute to a range of interpretations that cannot be subsumed under a semantic category or a specific temporal representation. The explanatory model presented in this paper builds upon relevancetheoretic
Differences in the incidence of hip fractures have been reported between urban and rural areas. In this population-based study the characteristics of fracture patterns between the city of Malmo and the nearby rural district of Sjobo were compared. A total of 782 individuals in Malmo and 486 in Sjobo were invited to participate. Fracture history for all invited was registered. The odds ratio for fr
Over the years, there has been much debate regarding the conformational behavior of flexible polyelectrolytes with electrostatic interactions described by the D bye-Huckel approximation. In particular, the electrostatic persistence length has been reported to depend both quadratically and linearly on the screening length as well as having no consistent power-law dependence at all. On the basis of
The phylogeny of two lichens, Cetraria obtusata from the Alps and Coelopogon epiphorellus occurring in the southern hemisphere is studied. A DNA-matrix based on ITS 1 and ITS 2 sequences of the rDNA is compared with a data set composed of morphology and secondary chemistry characters in phylogeny analyses using PAUP 4.0. The two data sets were entirely congruent. Neither Cetraria obtusata nor Coel
CONCLUSIONS: The results of the present study suggest that the pancreas and parotid glands both respond with hypoplasia during absence of food in the digestive tract and with hyperplasia following pancreatico-biliary diversion (PBD). Factors other than cholecystokinin (CCK) are, however, involved in the effects on the parotid glands, since infusion of CCK-8S and devazepide was without influence. B
The main topic of the thesis is the connection between representation theory and special functions. We study matrix elements, coupling coefficient, and recoupling coefficients for the simplest Lie and quantum groups. We show that a large number of multivariable orthogonal and biorthogonal polynomials occurring in the literature may be obtained as coupling coefficients (generalized Clebsch-Gordan
The purpose of this report is to present a critical review of research and practice based knowledge about factors conductive to ”good functioning” of work teams in the light of the evolving knowledge of developmental processes in groups. Conceptions of work team effectiveness are critically evaluated and new formulations presented. Factors such as two-way causality, boundary based defintions of te
