    Formal descriptions of material manipulations: an exploration with cuts and shadows

    Shape computation in design is never purely limited to visual aspects and ideally includes material aspects as well. The physicality of designing introduces a wide range of variables for designers to tackle within the design process. We present a simple design exercise realised in four stages where we physically manipulate perforated cardboard sheets as a case to make material variables explicit in the computation. The emphasis is on representing sensory aspects rather than easily quantifiable properties more suitable for simulations. Our explorations demonstrate the use of visual rules to represent actions, variables and form as well as how to control the variables to create new results, both desired and surprising, in materially informed ways

    The paradox of agency: feeling powerful reduces brokerage opportunity recognition yet increases willingness to broker

    Get PDF
    Research suggests positions of brokerage in organizational networks provide many benefits, but studies tend to assume everyone is equally able to perceive and willing to act on brokerage opportunities. Here we challenge these assumptions in a direct investigation of whether people can perceive brokerage opportunities and are willing to broker. We propose that the psychological experience of power diminishes individuals’ ability to perceive opportunities to broker between people who are not directly connected in their networks, yet enhances their willingness to broker. In Study 1, we find that employees in a marketing and media agency who had a high sense of power were likely to see fewer brokerage opportunities in their advice networks. In Study 2, we provide causal evidence for this claim in an experiment where the psychological experience of power is manipulated. Those who felt powerful, relative to those who felt little power, tended to see fewer brokerage opportunities than actually existed, yet were more willing to broker, irrespective of whether there was a brokerage opportunity present. Collectively, these findings present a paradox of agency: Individuals who experience power are likely to underperceive the very brokerage opportunities for which their sense of agency is suited.

    BACKGROUND: Patients in intensive care units (ICUs) are at high risk of developing physical, functional, cognitive, and mental impairments. Early mobilisation aims to improve patient outcomes and is increasingly considered the standard of care. This survey aimed to investigate the characteristics, current use and variations of early mobilisation and rehabilitation in Swiss ICUs. METHODS: We conducted a cross-sectional survey among all ICU lead physicians, who provided data on their institutional characteristics, early mobilisation and rehabilitation practices, and their perceptions of the use and variation of early rehabilitation practices in Switzerland. RESULTS: The survey response rate was 44% (37/84). Among ICUs caring for adults (34/37), 26 were in the German-speaking region, five in the French-speaking region, and three in the Italian-speaking region. All ICUs regularly involved physiotherapy in the rehabilitation process and 50% reported having a specialised physiotherapy team. All ICUs reported performing early mobilisation, starting within the first 7 days after ICU admission. About half reported the use of a rehabilitation (45%) or early mobilisation protocol (50%). Regular, structured, interdisciplinary rounds or meetings of the ICU care team to discuss rehabilitation measures and goals for patients were stated to be held by 53%. The respondents stated that 82% of their patients received early mobilisation measures during their ICU stay. Most frequently provided mobilisation measures included passive range of motion (97%), passive chair position in bed (97%), active range of motion muscle activation and training (88%), active side to side turning (91%), sitting on the edge of the bed (94%), transfer from bed to a chair (97%), and ambulation (94%). The proportion of ICUs providing a specific early mobilisation measure, the proportion of patients receiving it, and the time dedicated to it varied across language regions, hospital types, ICU types, and ICU sizes. Almost one third of the ICU lead physicians considered early rehabilitation to be underused in their own ICU and about half considered it to be underused in Switzerland more generally. ICU lead physicians stressed lack of personnel, financial resources, and time as key causes for underuse. Moreover, they highlighted the importance of early and systematic or protocol-based rehabilitation and interprofessional approaches that are adaptive to the patients' rehabilitation needs and potential. CONCLUSION: This survey suggests that almost all ICUs in Switzerland practice some form of early mobilisation with the aim of early rehabilitation. However, the described approaches, as well as the reported use of early mobilisation measures were heterogenous across Swiss ICUs

    Survival modelling and cost-effectiveness analysis of treatments for newly diagnosed metastatic hormone-sensitive prostate cancer

    Full text link
    Background In metastatic hormone-sensitive prostate cancer (mHSPC) treatment, survival benefits have been shown by adding docetaxel or recent androgen receptor axis-targeted therapies (ARATs) abiraterone, apalutamide, or enzalutamide to androgen deprivation therapy (ADT). However, the optimal treatment strategy in terms of costs and effects is unclear, not least due to high ARAT costs. Methods To assess treatment cost-effectiveness, we developed a Markov cohort model with health states of progression-free disease, progressive disease and death for men with newly diagnosed mHSPC, with a 30-year time horizon. Survival data, adverse events and utilities were informed by randomized controlled trial results, our meta-analysis of re-created individual patient survival data, and publicly available sources of unit costs. We applied a Swiss healthcare payer perspective and discounted costs and effects by 3%. Results We found a significant overall survival benefit for ADT+abiraterone versus ADT+docetaxel. The corresponding incremental cost-effectiveness ratio (ICER) was predicted to be EUR 39,814 per quality-adjusted life-year (QALY) gained. ADT+apalutamide and ADT+enzalutamide incurred higher costs and lower QALYs compared to ADT+abiraterone. For all ARATs, drug costs constituted the most substantial cost component. Results were stable except for a large univariable reduction in the pre-progression utility under ADT+abiraterone and very large variations in drug prices. Conclusions Our model projected ADT+abiraterone to be cost-effective compared to ADT+docetaxel at a willingness-to-pay threshold of EUR 70,400/QALY (CHF 100,000 applying purchasing power parities). Given lower estimated QALYs for ADT+apalutamide and ADT+enzalutamide compared to ADT+abiraterone, the former only became cost-effective (the preferred) treatment option(s) at substantial 75–80% (80–90%) price reductions

    Treatments for Metastatic Hormone-sensitive Prostate Cancer: Systematic Review, Network Meta-analysis, and Benefit-harm assessment

    Full text link
    Context: Multiple treatments for metastatic, hormone-sensitive prostate cancer (mHSPC) are available, but their effects on health-related quality of life (HRQoL) and benefit-harm balance remain unclear. Objective: To assess clinical effectiveness regarding survival and HRQoL, safety, and benefit-harm balance of mHSPC treatments. Evidence acquisition: We searched MEDLINE, EMBASE, CENTRAL, and ClinicalTrials.gov until March 1, 2022. Randomized controlled trials (RCTs) comparing docetaxel, abiraterone, enzalutamide, apalutamide, darolutamide, and radiotherapy combined with androgen deprivation therapy (ADT) mutually or with ADT alone were eligible. Three reviewers independently performed screening, data extraction, and risk of bias assessment in duplicate. Evidence synthesis: Across ten RCTs, we found relevant survival benefits for ADT + docetaxel (high certainty according to the Grading of Recommendations, Assessment, Development and Evaluation [GRADE]), ADT + abiraterone (moderate certainty), ADT + enzalutamide (low certainty), ADT + apalutamide (high certainty), and ADT + docetaxel + darolutamide (high certainty) compared with ADT alone. ADT + radiotherapy appeared effective only in low-volume de novo mHSPC. We found a short-term HRQoL decrease lasting 3-6 mo for ADT + docetaxel (moderate certainty) and a potential HRQoL benefit for ADT + abiraterone up to 24 mo of follow-up (moderate certainty) compared with ADT alone. There was no difference in HRQoL for ADT + enzalutamide, ADT + apalutamide, or ADT + radiotherapy over ADT alone (low-high certainty). Grade 3-5 adverse effect rates were increased with all systemic combination treatments. A benefit-harm assessment showed high probabilities (>60%) for a net clinical benefit with ADT + abiraterone, ADT + enzalutamide, and ADT + apalutamide, while ADT + docetaxel and ADT + docetaxel + darolutamide appeared unlikely (<40%) to be beneficial. Conclusions: Despite substantial survival benefits, no systemic combination treatment showed a clear HRQoL improvement compared with ADT alone. We found evidence for a short-term HRQoL decline with ADT + docetaxel and a higher net clinical benefit with ADT + abiraterone, ADT + apalutamide and ADT + enzalutamide. While individualized decision-making remains important and economic factors need to be considered, the evidence may support a general preference for the combination of ADT with androgen receptor axis-targeted therapies over docetaxel-containing strategies. Patient summary: We assessed different combination treatments for metastatic hormone-sensitive prostate cancer. While survival was better with all systemic combination treatments, there was no clear improvement in health-related quality of life compared with androgen deprivation therapy alone. Novel hormonal combination treatments had a more favorable benefit-harm balance than combination treatments that include chemotherapy.

    It Works Without Words: A Nonlinguistic Ability Test of Perceiving Emotions with Job-Related Consequences

    Get PDF
    This is the final version. Available on open access from Hogrefe via the DOI in this recordEmotion recognition ability of emotions expressed by other people (ERA-O) can be important for job performance, leadership, bargaining, and career success. Traditional personnel assessment tools of this ability, however, are contaminated by linguistic skills. In a time of global work migration, more and more people speak a language at work that is not their mother tongue. Consequently, we developed and validated the Face-Based Emotion Matching Test (FEMT), a nonlinguistic objective test of ERA-O in gainfully employed adults. We demonstrate the FEMT’s validity with psychological constructs (cognitive and emotional intelligence, Big Five personality traits) and its criterion validity and interethnic fit

    Why growth equals power - and why it shouldn't : constructing visions of China

    Get PDF
    When discussing the success of China's transition from socialism, there is a tendency to focus on growth figures as an indication of performance. Whilst these figures are indeed impressive, we should not confuse growth with development and assume that the former necessarily automatically generates the latter. Much has been done to reduce poverty in China, but the task is not as complete as some observers would suggest; particularly in terms of access to health, education and welfare, and also in dealing with relative (rather than absolute) depravation and poverty. Visions of China have been constructed that exaggerate Chinese development and power in the global system partly to serve political interests, but partly due to the failure to consider the relationship between growth and development, partly due to the failure to disaggregate who gets what in China, and partly due to the persistence of inter-national conceptions of globalised production, trade, and financial flows

    Genomic organization and evolutionary conservation of plant D-type cyclins

    Plants contain more genes encoding core cell cycle regulators than other organisms but it is unclear whether these represent distinct functions. D-type cyclins (CYCD) play key roles in the G1-to-S-phase transition, and Arabidopsis (Arabidopsis thaliana) contains 10 CYCD genes in seven defined subgroups, six of which are conserved in rice (Oryza sativa). Here, we identify 22 CYCD genes in the poplar (Populus trichocarpa) genome and confirm that these six CYCD subgroups are conserved across higher plants, suggesting subgroup-specific functions. Different subgroups show gene number increases, with CYCD3 having three members in Arabidopsis, six in poplar, and a single representative in rice. All three species contain a single CYCD7 gene. Despite low overall sequence homology, we find remarkable conservation of intron/exon boundaries, because in most CYCD genes of plants and mammals, the first exon ends in the conserved cyclin signature. Only CYCD3 genes contain the complete cyclin box in a single exon, and this structure is conserved across angiosperms, again suggesting an early origin for the subgroup. The single CYCD gene of moss has a gene structure closely related to those of higher plants, sharing an identical exon/intron structure with several higher plant subgroups. However, green algae have CYCD genes structurally unrelated to higher plants. Conservation is also observed in the location of potential cyclin-dependent kinase phosphorylation sites within CYCD proteins. Subgroup structure is supported by conserved regulatory elements, particularly in the eudicot species, including conserved E2F regulatory sites within CYCD3 promoters. Global expression correlation analysis further supports distinct expression patterns for CYCD subgroups

    Responsibility and appropriate blame: The no difference view

    Get PDF
    How do the fact that an agent is morally responsible for a certain morally objectionable action and the fact that she is an appropriate target of blame for it relate to each other? Many authors inspired by Peter Strawson say that they necessarily co‐occur. Standard answers to the question of why they co‐occur say that the occurrence of one of the facts explains that the other obtains. This article presents a third option: that they are one and the same fact. There is no difference between the fact that a person is an appropriate target of blame for an objectionable action and the fact that she is morally responsible for it. This view has the advantage of being metaphysically more parsimonious and of answering, in an elegant and plausible way, an interesting question about which many standard theories of responsibility keep silent: what is it to be morally responsible simpliciter
