Uncovering the meaning of ‘being safe’ in practice

Abstract This paper moves away from the prevalent discourse of competence to consider the meaning of the experience of ‘being safe’ within the context of childbirth. It offers findings from a doctoral study, informed by the philosophies of Heidegger and Gadamer. Following ethical approval, the data was collected in New Zealand by tape-recorded interviews of 5 midwives, 4 obstetricians, 1 general practitioner and 10 women. The method was informed by van Manen. The findings reveal that in seeking the meaning of being safe one needs to be aware that the unsafety may already be present in the situation. Practitioners may be able to do little to rectify the unsafeness. There is, however, a spirit of safe practice, explicated in this paper, that is likely to make practice as safe as it can possibly be. Wise practitioners are ever mindful that a situation may be or become unsafe, and are always aware of their own limitations.
The Multitrait-Multimethod Approach in Family Assessment

Abstract. A questionnaire and two observation methods were used to assess the parent-child relationship constructs Warmth, Hostility, Respect for Autonomy, and Setting Limits. Family members (father, mother, and one child) were asked to assess each of the other family members on these constructs. The family members were observed during an interaction task and their behavior toward each of the other family members was coded on these constructs, using global ratings and microcodes. The children's problem behavior was rated by both parents. A multitrait-multimethod approach was followed in analyzing the data and interpreting the criterion validity of the relationship measures. Method-variance overshadowed trait-variance and presumably also explained the moderate criterion validity of the questionnaire and the behavior rating method.
Super-resolution imaging using a three-dimensional metamaterials nanolens

Super-resolution imaging beyond Abbe’s diffraction limit can be achieved by utilizing an optical medium or “metamaterial” that can either amplify or transport the decaying near-field evanescent waves that carry subwavelength features of objects. Earlier approaches at optical frequencies mostly utilized the amplification of evanescent waves in thin metallic films or metal-dielectric multilayers, but were restricted to very small thicknesses (⪡λ, wavelength) and accordingly short object-image distances, due to losses in the material. Here, we present an experimental demonstration of super-resolution imaging by a low-loss three-dimensional metamaterial nanolens consisting of aligned gold nanowires embedded in a porous alumina matrix. This composite medium possesses strongly anisotropic optical properties with negative permittivity in the nanowire axis direction, which enables the transport of both far-field and near-field components with low-loss over significant distances (>6λ), and over a broad spectral ra.
Endometrial stromal cells: isolation, expansion, morphological and functional properties.

AIM We aimed to study biological properties of human endometrial stromal cells in vitro. MATERIALS AND METHODS The endometrium samples (n = 5) were obtained by biopsy at the first phase of the menstrual cycle from women with endometrial hypoplasia. In all cases, a voluntary written informed consent was obtained from the patients. Endometrial fragments were dissociated by enzymatic treatment. The cells were cultured in DMEM/F12 supplemented with 10% FBS, 2 mМ L-glutamine and 1 ng/ml FGF-2 in a multi-gas incubator at 5% CO2 and 5% O2. At P3 the cells were subjected to immunophenotyping, multilineage differentiation, karyotype stability and colony forming efficiency. The cell secretome was assessed by BioRad Multiplex immunoassay kit. RESULTS Primary population of endometrial cells was heterogeneous and contained cells with fibroblast-like and epithelial-like morphology, but at P3 the majority of cell population had fibroblast-like morphology. The cells possessed typical for MSCs phenotype CD90+CD105+CD73+CD34-CD45-HLA-DR-. The cells also expressed CD140a, CD140b, CD146, and CD166 antigents; and were negative for CD106, CD184, CD271, and CD325. Cell doubling time was 29.6 ± 1.3 h. The cells were capable of directed osteogenic, adipogenic and chondrogenic differentiation. The cells showed 35.7% colony forming efficiency and a tendency to 3D spheroid formation. The GTG-banding assay confirmed the stability of eMSC karyotype during long-term culturing (up to P8). After 48 h incubation period in serum-free medium eMSC secreted anti-inflammatory IL-1ra, as well as IL-6, IL-8 and IFNγ, angiogenic factors VEGF, GM-CSF and FGF-2, chemokines IP-10 and MCP-1. CONCLUSION Thus, cultured endometrial stromal cells meet minimal ISCT criteria for MSC. Proliferative potential, karyotype stability, multilineage plasticity and secretome profile make eMSC an attractive object for the regenerative medicine use.

GaN HEMT class-E rectifier for DC+AC power recovery

A 915 MHz GaN HEMT-based class-E rectifier is proposed in this paper to be used for DC+AC wireless power recovery. Taking advantage of the time reversal (TR) duality principle, the rectifier was derived from a class-E inverter, whose output network was designed for high-efficiency operation over a wide range of resistive loads. The addition of an appropriate gateside termination allows the device to be turned-on without an additional RF source for gate driving. The rectifier reduced sensitivity to load variation, as well as its capability for efficiently and linearly recovering the envelope of an AM RF excitation, were then characterized. An average efficiency of 82% has been measured for the combined RF-to-DC and RF-to-AC power conversion of a 1.6 W modulated carrier. Frequency multiplexing and frequency modulation alternatives for high-level DC+AC wireless power transmission are finally presented.
Get off my bus! School leaders, vision work and the elimination of teachers

In this paper, we argue that school leaders are removing those who embody or vocalize alternative conceptualizations of educator. It seems as if Collins’ call in his 2001 book Good to Great to get the right people on the bus is being taken very seriously by school leaders seeking to raise standards. This is achieved by eradicating ‘inadequate’ teaching, and implementing the leader’s ‘vision’, which we argue consists in silencing and potentially removing professional voice, knowledge and contributions. We present data from nine headteachers who talk about their vision and vision work, and in deploying Arendtian thinking, we think the unthinkable about how teachers can be rendered disposable and are disposed of. Arendt’s political thinking tools help us to consider how, through routine practices, current models of school leadership enable totalitarian practices to become ordinary.
Creating Scenes for an Intelligent Nursing Environment: Co-design and User Evaluations of a Home Control System

In this paper we describe the co-design process of a proof-of-concept home control system, and how it was carried out by utilising a user-centred design methodology. The aim was to develop a demonstrator of a home control system that supports elderly people in living more independently in their homes. The focus of the research was on the configuration tool of the environment, which was meant to be exploited in a nursing home. The home control system was intended to be used and configured by non-technologically versed users: mainly the care personnel, but also the inhabitants and their close relatives. The system was co-designed and evaluated at first with nurses, who were considered to be the local experts of the chosen ecosystem. The final web-based proof-of-concept system was evaluated with nurses and end-users.
Dominant discourses of pre‐service teacher education and the exigencies of the workplace: an ethnographic study from English further education

The placement in colleges is a crucially formative experience for trainee teachers on pre‐service Further Education (FE) initial teacher training courses. A project at the University of Huddersfield researched these placements in four colleges in the north of England and the relationships that were formed between the trainees, their mentors, other staff and students. Where the trainees were placed and who they taught were often matters of expedience, and their individual circumstances were contingent upon diverse, often local, factors. As such, the picture that emerged of the lived experience of placement defied simple classification and explanation. Drawing on data gathered during the project this paper argues that the experience of placements is characterised by confusion, insecurity and marginalisation on the one hand and integration, enthusiasm and development on the other. Regardless of their individual experience, however, there is evidence that the trainees learnt to cope and even that messiness may be useful preparation for the unstable FE workplace. The paper problematises the developmental basis for placements and questions what constitutes a successful placement before considering how trainees can be best prepared to teach in the FE sector.
High incidence of tachyarrhythmias detected by an implantable loop recorder in patients with unexplained syncope.

BACKGROUND Syncope is a complex clinical syndrome that may be challenging with respect to a definite diagnosis. The implantable loop recorder (ILR) is a useful tool to define but also to exclude an arrhythmic aetiology. AIM To investigate the causes of recurrent syncope or near-syncope with respect to underlying arrhythmias in non-selected consecutive patients monitored with an ILR. METHODS A retrospective study was conducted including 55 patients (34 men, 21 women; age 60+/-19 years) with unexplained syncope who received an ILR for prolonged monitoring at our institution between April 1998 and October 2006. RESULTS Forty (73%) patients had a recurrence of syncope or near-syncope. Structural heart disease was present in 18 (33%) patients, 4 of them having an ejection fraction <35%. An arrhythmia was detected as the cause of syncope in 25 (46%) patients. The ILR was successful in establishing a symptom-rhythm correlation in 63%. The mean follow-up period from implantation to occurrence of the detected arrhythmias was 9+/-8 months. Bradyarrhythmias were recorded in 12 (22%) patients, whereas tachyarrhythmias were found in 13 (24%) patients. Narrow QRS tachycardia was the underlying arrhythmia in 6 patients and wide QRS tachycardia in 7 patients. A pacemaker was implanted in all 12 patients with bradyarrhythmias. Implantable cardioverter defibrillator (ICD) therapy was indicated in 6 patients with adjunctive catheter ablation in 3 of them. Four patients presenting with paroxysmal supraventricular tachycardia were treated with radiofrequency catheter ablation. CONCLUSION The ILR helped efficaciously to determine the correct diagnosis and appropriate treatment of recurrent syncope. A considerably high proportion of tachyarrhythmias was detected in this non-selected consecutive population. The majority of patients with tachyarrhythmic syncope required defibrillator implantation and/or radiofrequency ablation.
Nonstationarities of postural sway

Time-frequency analysis of visually induced postural sway has uncovered potentially important time-dependent spectral changes in sway, particularly over intervals shorter than most trial lengths (tens of seconds). Specifically, our studies of center of pressure (COP) in response to sinusoidal (0.25 Hz) moving scene perturbations demonstrate that there are significant population-dependent time-varying changes in response to such visual perturbations, manifest in the instantaneous power at the stimulus frequency, and in low-order conditional moments of the time-varying spectral density of sway (the conditional mean frequency and bandwidth, also called the instantaneous frequency and the instantaneous bandwidth). In particular, adaptation, as quantified by a decrease in the instantaneous power of sway over time at the stimulus frequency, was observed in the control and elderly subjects but not in the vestibularly impaired group. We believe that these quantities are important measures for studying time-variations in postural sway and that continued application of nonstationary analysis methods such as time-frequency analysis is necessary to better understand and model time-varying aspects of balance.
Political deliberation and the challenge of bounded rationality

Many proponents of deliberative democracy expect reasonable citizens to engage in rational argumentation. However, this expectation runs up against findings by behavioral economists and social psychologists revealing the extent to which normal cognitive functions are influenced by bounded rationality. Individuals regularly utilize an array of biases in the process of making decisions, which inhibits our argumentative capacities by adversely affecting our ability and willingness to be self-critical and to give due consideration to others’ interests. Although these biases cannot be overcome, I draw on scientifically corroborated insights offered by Adam Smith to show that they can be kept in check if certain affective and cognitive capacities are cultivated. Smith provides a compelling account of how to foster sympathetic, impartial, and projective role-taking in the process of interacting with others, which can greatly enhance our capacity and willingness to critically assess our own interests and fairly consider those of others.
Why the communicable/non-communicable disease dichotomy is problematic for public health control strategies: implications of multimorbidity for health systems in an era of health transition

In today's globalized world, rapid urbanization, mechanization of the rural economy, and the activities of trans-national food, drink and tobacco corporations are associated with behavioral changes that increase the risk of chronic non-communicable diseases (NCDs). These changes include less healthy diet, lower physical activity, tobacco smoking and increased alcohol consumption. As a result, population health profiles are rapidly changing. For example, the global burden of type 2 diabetes mellitus is expected to double by 2030, with 80% of adult cases occurring in low and middle-income countries (LMIC). Many LMIC are undergoing rapid changes associated with developing high rates of NCD while concomitantly battling high levels of certain communicable diseases, including HIV, TB and malaria. This has population health, health systems and economic implications for these countries. This critical review synthesizes evidence on the overlap and interactions between established communicable and emerging NCD epidemics in LMIC. The review focuses on HIV, TB and malaria and explores the disease-specific interactions with prevalent NCDs in LMIC including diabetes, cardiovascular disease, chronic obstructive pulmonary disease, chronic renal disease, epilepsy and neurocognitive diseases. We highlight the complexity, bi-directionality and heterogeneity of these interactions and discuss the implications for health systems.
Memory-Scalable GPU Spatial Hierarchy Construction

Recent GPU algorithms for constructing spatial hierarchies have achieved promising performance for moderately complex models by using the breadth-first search (BFS) construction order. While being able to exploit the massive parallelism on the GPU, the BFS order also consumes excessive GPU memory, which becomes a serious issue for interactive applications involving very complex models with more than a few million triangles. In this paper, we propose to use the partial breadth-first search (PBFS) construction order to control memory consumption while maximizing performance. We apply the PBFS order to two hierarchy construction algorithms. The first algorithm is for kd-trees that automatically balances between the level of parallelism and intermediate memory usage. With PBFS, peak memory consumption during construction can be efficiently controlled without costly CPU-GPU data transfer. We also develop memory allocation strategies to effectively limit memory fragmentation. The resulting algorithm scales well with GPU memory and constructs kd-trees of models with millions of triangles at interactive rates on GPUs with 1 GB memory. Compared with existing algorithms, our algorithm is an order of magnitude more scalable for a given GPU memory bound. The second algorithm is for out-of-core bounding volume hierarchy (BVH) construction for very large scenes based on the PBFS construction order. At each iteration, all constructed nodes are dumped to the CPU memory, and the GPU memory is freed for the next iteration's use. In this way, the algorithm is able to build trees that are too large to be stored in the GPU memory. Experiments show that our algorithm can construct BVHs for scenes with up to 20 M triangles, several times larger than previous GPU algorithms.
Editorial Conceptual Framework Elaborating the Profiles Profile A: Back to the Basics

CONCEPTUAL FRAMEWORK This special issue addresses the questions: What is the role and impact of Information and Communications Technology (ICT) on the process of internationalization in higher education? How is this internationalization process related to general models of change that are in motion? In particular, the articles in this special issue explore how the use of ICT influences the future international missions, profiles, and (market) orientations of higher education institutions. In our own work (Collis & Gommer, 2001; Collis & Moonen, 2001; van der Wende, 2001, in press), we have used two dimensions that we have derived as being critical for analyzing (and predicting) the different strategic pathways that higher education institutions may choose with respect to the future use of ICT in their international strategies. These dimensions are
From Digitized Images to Online Catalogs: Data Mining a Sky Survey

The value of scientific digital-image libraries seldom lies in the pixels of images. For large collections of images, such as those resulting from astronomy sky surveys, the typical useful product is an online database cataloging entries of interest. We focus on the automation of the cataloging effort of a major sky survey and the availability of digital libraries in general. The SKICAT system automates the reduction and analysis of the three terabytes worth of images, expected to contain on the order of 2 billion sky objects. For the primary scientific analysis of these data, it is necessary to detect, measure, and classify every sky object. SKICAT integrates techniques for image processing, classification learning, database management, and visualization. The learning algorithms are trained to classify the detected objects and can classify objects too faint for visual classification with an accuracy level exceeding 90 percent. This accuracy level increases the number of classified objects in the final catalog threefold relative to the best results from digitized photographic sky surveys to date. Hence, learning algorithms played a powerful and enabling role and solved a difficult, scientifically significant problem, enabling the consistent, accurate classification and the ease of access and analysis of an otherwise unfathomable data set.
New Labour, New Britain, new sexual values?

This article investigates changing parameters of 'privacy' in Britain and their relevance for the redrawing of boundaries between 'acceptable' and 'unacceptable' sexualities. Drawing on Berlant's distinction between 'live' sex acts and 'dead identities', the article suggests that some hitherto 'live' sex act may 'die', leaving others to be rejected and policed, perhaps even with renewed vigour. This may not, however, mean that the normative status of conjugal (hetero)sexuality is moribund: it may merely be reinvented. The article focuses primarily on the heated and often sensationalized public debate on the homosexuality of Members of Parliament which gripped the UK during October and November 1998. Tony Blair's Labour government was elected to power in 1997 under the campaign slogan 'New Labour, New Britain', and the public reaction to the homosexuality of MPs in 1998 led many commentators to conclude that British sexual values were undergoing a profound liberalization. It is questionable, however, whether these 'new' sexual values were actually as new, or as liberal, as they appeared.
Accuracy , Unbiasedness and Efficiency of Professional Macroeconomic Forecasts : An empirical Comparison for the G 7 by Jonas Dovern

In this paper, we use survey data to analyze the accuracy, unbiasedness, and the efficiency of professional macroeconomic forecasts. We analyze a large panel of individual forecasts that has not been analyzed in the literature so far. We provide evidence on the properties of forecasts for all G7 counties and for four different macroeconomic variables. Our results show a high degree of dispersion of forecast accuracy across forecasters. We also find that there are large differences in the performance of forecasters not only across countries but also across different macroeconomic variables. In general, forecasts tend to be biased in situations where forecasters have to respond to large structural shocks or gradual changes in the trend of a variable. Furthermore, while a sizable fraction of forecasters seem to smooth their GDP forecasts significantly, this does not apply to forecasts made for other macroeconomic variables.
Arabidopsis Ribosomal Proteins RPL23aA and RPL23aB Are Differentially Targeted to the Nucleolus and Are Disparately Required for Normal Development1[C][W][OA]

Protein synthesis is catalyzed by the ribosome, a two-subunit enzyme comprised of four ribosomal RNAs and, in Arabidopsis (Arabidopsis thaliana), 81 ribosomal proteins (r-proteins). Plant r-protein genes exist as families of multiple expressed members, yet only one r-protein from each family is incorporated into any given ribosome, suggesting that many r-protein genes may be functionally redundant or development/tissue/stress specific. Here, we characterized the localization and gene-silencing phenotypes of a large subunit r-protein family, RPL23a, containing two expressed genes (RPL23aA and RPL23aB). Live cell imaging of RPL23aA and RPL23aB in tobacco with a C-terminal fluorescent-protein tag demonstrated that both isoforms accumulated in the nucleolus; however, only RPL23aA was targeted to the nucleolus with an N-terminal fluorescent protein tag, suggesting divergence in targeting efficiency of localization signals. Independent knockdowns of endogenous RPL23aA and RPL23aB transcript levels using RNA interference determined that an RPL23aB knockdown did not alter plant growth or development. Conversely, a knockdown of RPL23aA produced a pleiotropic phenotype characterized by growth retardation, irregular leaf and root morphology, abnormal phyllotaxy and vasculature, and loss of apical dominance. Comparison to other mutants suggests that the phenotype results from reduced ribosome biogenesis, and we postulate a link between biogenesis, microRNA-target degradation, and maintenance of auxin homeostasis. An additional RNA interference construct that coordinately silenced both RPL23aA and RPL23aB demonstrated that this family is essential for viability.
