Building life world connections during school booktalk

In criticisms of children's literature, notions of 'fantasy' and 'realism' are pivotal. In school 'booktalk' conversations pupils referred to what is 'real' in three different ways: (i) by referring to feelings of or semblance to 'real' life, (ii) by invoking shared facts and (iii) by making references to personal experiences. In cases when teachers or pupils initiated so-called text-to-life or real world connections, two types of dilemmas occurred. First, engagement was at times bought at the cost of quite literal reader responses. At other times, engagement was accomplished at the price of intrusiveness. There was, thus, a delicate balance between life world references, on the one hand, and literal readings or intrusion, on the other. Moreover, students sometimes resisted life world probing, but volunteered privileged information about their parents, displaying different notions from teachers about legitimate information in a school context.     

Comprehending conflicting science-related texts: graphs as plausibility cues

When reading conflicting science-related texts, readers may attend to cues which allow them to assess plausibility. One such plausibility cue is the use of graphs in the texts, which are regarded as typical of ‘hard science’. The goal of our study was to investigate the effects of the presence of graphs on the perceived plausibility and situation model strength for conflicting science-related texts, while including the influence of readers’ amount of experience with scientific texts and graphs as a potential moderator of these effects. In an experiment mimicking web-based informal learning, 77 university students read texts on controversial scientific issues which were presented with either graphs or tables. Perceived plausibility and situation model strength for each text were assessed immediately after reading; reader variables were assessed several weeks prior to the experiment proper. The results suggest that graphs can indeed serve as plausibility cues and thus boost situation model strength for texts which contain them. This effect was mediated by the perceived plausibility of the information in the texts with graphs. However, whether readers use graphs as plausibility cues in texts with conflicting information seems to depend also on their amount of experience with scientific texts and graphs.     

A Test Collection for the Evaluation of Content-Based Image Retrieval Algorithms—A User and Task-Based Approach

Content-based image retrieval (CBIR) algorithms have been seen as a promising access method for digital photograph collections. Unfortunately, we have very little evidence of the usefulness of these algorithms in real user needs and contexts. In this paper, we introduce a test collection for the evaluation of CBIR algorithms. In the test collection, the performance testing is based on photograph similarity perceived by end-users in the context of realistic illustration tasks and environment. The building process and the characteristics of the resulting test collection are outlined, including a typology of similarity criteria expressed by the subjects judging the similarity of photographs. A small-scale study on the consistency of similarity assessments is presented. A case evaluation of two CBIR algorithms is reported. The results show clear correlation between the subjects' similarity assessments and the functioning of feature parameters of the tested algorithms.

Antipsychotics-induced hyperprolactinemia and screening for macroprolactin

IntroductionHigh prolactin (PRL) concentrations are found in laboratory test results of patients on majority of antipsychotic drugs. Prevalence rates and degrees of severity of hyperprolactinemia (HPRL) based on PRL concentration may depend on the presence of macroprolactin in the serum. The aim of the study was to investigate the difference between PRL concentrations before and after precipitation of macroprolactin and to examine if there were any changes in the categorization of HPRL between samples prior and after precipitation.Materials and methodsTotal of 98 female patients (median age 33; range 19-47 years) diagnosed with a psychotic disorder, proscribed antipsychotic drugs, and with HPRL were included. Total PRL concentration and PRL concentration after macroprolactin precipitation with polyethylene glycol (postPEG-PRL) were determined by the chemiluminometric method on the Beckman Coulter Access2 analyser.ResultsTotal PRL concentrations (median 1471; IQC: 1064-2016 mlU/L) and postPEG-PRL concentrations (median 1453; IQC: 979-1955 mlU/L) were significantly correlated using intraclass correlation coefficient for single measurements (mean estimation 0.96; 95%CI 0.93-0.97) and average measurement (mean estimation 0.98; 95%CI 0.96-0.99), and all investigated female patient had HPRL according to PRL and postPEG-PRL concentration. The median PRL recovery following PEG precipitation was 95; IQC: 90-100%. There was substantial agreement (kappa test = 0.859, 95% CI: 0.764-0.953) between the categories of HPRL severity based on total PRL concentrations and postPEG-PRL concentrations.ConclusionThe study demonstrated that HPRL was present in all subjects using the reference interval for total PRL concentration and postPEG-PRL concentration with no significant impact of macroprolactin presence in the serum on the categorization of patients according to severity of HPRL.     

Agency and structure in academic development practices: are we liberating academic teachers or are we part of a machinery supressing them?

This text taps into an ongoing discussion about academic development. It challenges an image of academic development as precarious and liminal and explores academic development as powerful. Sources of power are described and put into the context of values, ideologies, and policies governing higher education of today. It is our hope that readers will be inspired to problematise their own academic development practices and to reclaim a phase in the history of the profession where members displayed more of a political awareness.     

Understanding and influencing teaching and learning cultures at university: a network approach

Academic cultures might be perceived as conservative, at least in terms of development of teaching and learning. Through a lens of network theory this conceptual article analyses the pattern of pathways in which culture is constructed through negotiation of meaning. The perspective contributes to an understanding of culture construction and maintenance with a potential to aid academic developers and others in the endeavour to influence teaching and learning cultures in academia. Throughout the discussion the importance of supporting the weak links between clusters of individuals stands out as a feature to focus upon. We propose that the sheer complexity of culture construction and maintenance in academic organisations is likely to cause any single, isolated attempt for change to fail Instead, we argue that a multitude of inter-related initiatives over a long period of time is likely to distinguish strategies that are successful in influencing academic teaching and learning cultures.     

On the influence of the architecture of poly(ethylene glycol)-based thermoresponsive polymers on cell adhesion

Thermoresponsive polymer surface coatings are a promising tool for cell culture applications. They allow for a mild way of cell detachment that preserves the activity of membrane proteins—a prerequisite for reliable cell analysis. To enlarge the application range of these coatings to cells with different adhesion properties, we synthesized various novel poly(ethylene glycol)-based thermoresponsive polymers and describe how (i) their chemical structure and (ii) their surface density affect their efficiency. In order to quantify the influence of both factors, the time for cell spreading and rounding efficiency were observed. As a result, efficiency of cell rounding, which is closely correlated to cell detachment, is less affected by both factors than the time needed for cell spreading. This time can effectively be adjusted by the molecular architecture which includes the length of the polymer backbone and the side chains. Based on this work, recommendations are given for future optimization of functionality of thermoresponsive polymer coatings for cell culture applications.     

The ghosts of higher education reform: on the organisational processes surrounding policy borrowing

The Bologna Process is one of the most extensive examples of policy borrowing processes. Based on qualitative data, this article argues in favour of studying part of this process as ‘global smallness’, centring on the organisational effects of the implementation of a globalised curriculum. Through Derrida's notion on hauntology, Fenwick and Edward's analysis of multiple reals, and Barad's understanding of entanglement and time, this article explores how the implementation processes evoke simultaneously existing worlds of practices propelled by the agency of the past troubling present higher education reform. Finally, this article addresses how ongoing reforms tend to increase the stretch between ‘what is performed on the outside’ and ‘what is practiced on the inside’.
