"Touch me": workshop on tactile user experience evaluation methods

In this workshop we plan to explore the possibilities and challenges of physical objects and materials for evaluating the User Experience (UX) of interactive systems. These objects should face shortfalls of current UX evaluation methods and allow for a qualitative (or even quantitative), playful and holistic evaluation of UX -- without interfering with the users' personal experiences during interaction. This provides a tactile enhancement to a solely visual stimulation as used in classical evaluation methods. The workshop serves as a basis for networking and community building with interested HCI researchers, designers and practitioners and should encourage further development of the field of tactile UX evaluation

Eine Möglichkeit während dieser Behandlung die Temperatur zu kontrollieren, bietet die Kernspintomographie. Ihre Vorteile sind die gute Ortsauflösung, der gute Weichteilkontrast, die beliebige Wahl des Schnittbildverlaufs und ihr geringes Risiko für Nebenwirkungen. Innerhalb dieses Beitrags wird die Entwicklung einer quantitativen ort- und zeitaufgelösten Temperaturmessung im MR an einem gewebenahen Phantom vorgestellt

Structuring national and sub-national economic incentives to reduce emissions from deforestation in Indonesia

We estimate the impacts that alternative national and sub-national economic incentive structures for reducing emissions from deforestation (REDD+) in Indonesia would have had on greenhouse gas emissions and national and local revenue if they had been in place from 2000-2005. The impact of carbon payments on deforestation is calibrated econometrically from the pattern of observed deforestation and spatial variation in the benefits and costs of converting land to agriculture over that time period. We estimate that at an international carbon price of $10/tCO2e, a “basic voluntary incentive structure” modeled after a traditional payment-for-ecosystem-services (PES) program would have reduced emissions nationally by 62 MtCO2e/yr, or 8% below the without-REDD+ reference scenario (95% CI: 45-76 MtCO2e/yr; 6-9%), while generating a programmatic budget shortfall. By making four policy improvements—paying for net emission reductions at the scale of an entire district rather than site-by-site, paying for reductions relative to estimated business-as-usual levels rather than historical levels, sharing a portion of district-level revenues with the national government, and sharing a portion of the national government’s responsibility for costs with districts—an “improved voluntary incentive structure” would have reduced emissions by 175 MtCO2e/yr, or 22% below the reference scenario (95% CI: 136-207 MtCO2e/yr; 17-26%), while generating a programmatic budget surplus. A “regulatory incentive structure” such as a cap-and-trade or symmetric tax-and-subsidy program would have reduced emissions by 211/yr, or 26% below the reference scenario (95% CI: 163-247 MtCO2e/yr; 20-31%), and would not have required accurate predictions of business-as-usual emissions to guarantee a programmatic budget surplus.Climate change, land-use change, REDD+, reference levels, economic incentives

The definitive version was published in CHI PLAY '15 Proceedings of the 2015 Annual Symposium on Computer-Human Interaction in Play, https://doi.org/10.1145/2793107.2810260Serious and persuasive games and gamified interactions have become popular in the last years, especially in the realm of behavior change support systems. They have been used as tools to support and influence human behavior in a variety of fields, such as health, sustainability, education, and security. It has been shown that personalized serious and persuasive games and gamified interactions can increase effectivity of supporting behavior change compared to "one-size-fits all"-systems. However, how serious games and gamified interactions can be personalized, which factors can be used to personalize (e.g. personality, gender, persuadability, player types, gamification user types, states, contextual/situational variables), what effect personalization has (e.g. on player/user experience) and whether there is any return on investment is still largely unexplored. This full-day workshop aims at bringing together the academic and industrial community as well as the gaming and gamification community to jointly explore these topics and define a future roadmap.Österreichische ForschungsförderungsgesellschaftPeer-reviewe

Outcomes and risk score for distal pancreatectomy with celiac axis resection (DP-CAR) : an international multicenter analysis

Background: Distal pancreatectomy with celiac axis resection (DP-CAR) is a treatment option for selected patients with pancreatic cancer involving the celiac axis. A recent multicenter European study reported a 90-day mortality rate of 16%, highlighting the importance of patient selection. The authors constructed a risk score to predict 90-day mortality and assessed oncologic outcomes. Methods: This multicenter retrospective cohort study investigated patients undergoing DP-CAR at 20 European centers from 12 countries (model design 2000-2016) and three very-high-volume international centers in the United States and Japan (model validation 2004-2017). The area under receiver operator curve (AUC) and calibration plots were used for validation of the 90-day mortality risk model. Secondary outcomes included resection margin status, adjuvant therapy, and survival. Results: For 191 DP-CAR patients, the 90-day mortality rate was 5.5% (95 confidence interval [CI], 2.2-11%) at 5 high-volume (1 DP-CAR/year) and 18% (95 CI, 9-30%) at 18 low-volume DP-CAR centers (P=0.015). A risk score with age, sex, body mass index (BMI), American Society of Anesthesiologists (ASA) score, multivisceral resection, open versus minimally invasive surgery, and low- versus high-volume center performed well in both the design and validation cohorts (AUC, 0.79 vs 0.74; P=0.642). For 174 patients with pancreatic ductal adenocarcinoma, the R0 resection rate was 60%, neoadjuvant and adjuvant therapies were applied for respectively 69% and 67% of the patients, and the median overall survival period was 19months (95 CI, 15-25months). Conclusions: When performed for selected patients at high-volume centers, DP-CAR is associated with acceptable 90-day mortality and overall survival. The authors propose a 90-day mortality risk score to improve patient selection and outcomes, with DP-CAR volume as the dominant predictor

Simultaneous Magneto-Optical Trapping of Two Lithium Isotopes

We confine 4 10^8 fermionic 6Li atoms simultaneously with 9 10^9 bosonic 7Li atoms in a magneto-optical trap based on an all-semiconductor laser system. We optimize the two-isotope sample for sympathetic evaporative cooling. This is an essential step towards the production of a quantum-degenerate gas of fermionic lithium atoms.Comment: 4 pages, 3 figure

Minimally invasive versus open pancreatoduodenectomy (LEOPARD-2): Study protocol for a randomized controlled trial

Background: Data from observational studies suggest that minimally invasive pancreatoduodenectomy (MIPD) is superior to open pancreatoduodenectomy regarding intraoperative blood loss, postoperative morbidity, and length of hospital stay, without increasing total costs. However, several case-matched studies failed to demonstrate superiority of MIPD, and large registry studies from the USA even suggested increased mortality for MIPDs performed in low-volume (< 10 MIPDs annually) centers. Randomized controlled multicenter trials are lacking but clearly required. We hypothesize that time to functional recovery is shorter after MIPD compared with open pancreatoduodenectomy, even in an enhanced recovery setting. Methods/design: LEOPARD-2 is a randomized controlled, parallel-group, patient-blinded, multicenter, phase 2/3, superiority trial in centers that completed the Dutch Pancreatic Cancer Group LAELAPS-2 training program for laparoscopic pancreatoduodenectomy or LAELAPS-3 training program for robot-assisted pancreatoduodenectomy and have performed ≥ 20 MIPDs. A total of 136 patients with symptomatic benign, premalignant, or malignant disease will be randomly assigned to undergo minimally invasive or open pancreatoduodenectomy in an enhan

Qualitätsmanagement in organisationsinternen Wikis am Beispiel des Wiki-Service der Bundeswehr

Obwohl die wenigen bisher erschienenen Studien zur Qualität von Inhalten in Wikis und besonders der Wikipedia ein hohes Potential für die Erstellung auch verlässlicher Inhalte vermuten lassen, existiert noch kein formales und anerkanntes Qualitätsmanagementsystem für partizipativ erstellte Inhalte im organisationsinternen Web 2.0. Im Rahmen der Erprobung eines Wiki-Services für das Intranet der Bundeswehr wird derzeit ein solches System entwickelt und im laufenden Experiment evaluiert

Modulation of Conductance and Ion Selectivity of OmpF Porin by La3+ Ions

Background: Auditing is an important tool to identify practice variation and 'best practices'. The Dutch Pancreatic Cancer Audit is mandatory in all 18 Dutch centers for pancreatic surgery. Methods: Performance indicators and case-mix factors were identified by a PubMed search for randomized controlled trials (RCT's) and large series in pancreatic surgery. In addition, data dictionaries of two national audits, three institutional databases, and the Dutch national cancer registry were evaluated. Morbidity, mortality, and length of stay were analyzed of all pancreatic resections registered during the first two audit years. Case ascertainment was cross-checked with the Dutch healthcare inspectorate and key-variables validated in all centers. Results: Sixteen RCT's and three large series were found. Sixteen indicators and 20 case-mix factors were included in the audit. During 2014-2015, 1785 pancreatic resections were registered including 1345 pancreatoduodenectomies. Overall in-hospital mortality was 3.6%. Following pancreatoduodenectomy, mortality was 4.1%, Clavien-Dindo grade >= III morbidity was 29.9%, median (IQR) length of stay 12 (9-18) days, and readmission rate 16.0%. In total 97.2% of >40,000 variables validated were consistent with the medical charts. Conclusions: The Dutch Pancreatic Cancer Audit, with high quality data, reports good outcomes of pancreatic surgery on a national level
