Are We The One?

A collaborative, performative and relational experience for two people, woven together by a custom digital phone App. Two walkers, who have never met, simultaneously use a phone App to record a personalised walk around their locality, crafting a series of special moments and surprises for each other. The App then allows participants to continue their two walks, but now directed by what the other person has just created for them. Finally, at the end of the experience they can then choose whether they would like to actually meet in person. Based loosely on the idea of a date, each participant is initially asked to give a little bit of personal information, and then actually speak volumes about themselves through how they choose to care for their 'date's future experience. After walking in parallel universes, but never far away from each other, both daters can ultimately choose to then meet in person -- if what they have experienced tells them that maybe "We Are The One".

Structuring time and questioning to achieve tactical awareness in games lessons

Background: A paradigm shift in educational policy to create problem solvers and critical thinkers produced the games concept approach (GCA) in Singapore's Revised Syllabus for Physical Education (1999). A pilot study (2001) conducted on 11 primary school student teachers (STs) using this approach identified time management and questioning as two of the major challenges faced by novice teachers. Purpose: To examine the GCA from three perspectives: structure—lesson form in terms of teacher-time and pupil-time; product—how STs used those time fractions; and process—the nature of their questioning (type, timing, and target). Participants and setting: Forty-nine STs from three different PETE cohorts (two-year diploma, four-year degree, two-year post-graduate diploma) volunteered to participate in the study conducted during the penultimate week of their final practicum in public primary and secondary schools. Intervention: Based on the findings of the pilot study, PETE increased the emphasis on GCA content specific knowledge and pedagogical procedures. To further support STs learning to actualise the GCA, authentic micro-teaching experiences that were closely monitored by faculty were provided in schools nearby. Research design: This is a descriptive study of time-management and questioning strategies implemented by STs on practicum. Each lesson was segmented into a number of sub-categories of teacher-time (organisation, demonstration and closure) and pupil-time (practice time and game time). Questions were categorised as knowledge, technical, tactical or affective. Data collection: Each ST was video-taped teaching a GCA lesson towards the end of their final practicum. The STs individually determined the timing of the data collection and the lesson to be observed. Data analysis: Each lesson was segmented into a number of sub-categories of both teacher- and pupil-time. Duration recording using Noldus software (Observer 4.0) segmented the time management of different lesson components. Questioning was coded in terms of type, timing and target. Separate MANOVAs were used to measure the difference between programmes and levels (primary and secondary) in relation to time-management procedures and questioning strategies. Findings: No differences emerged between the programmes or levels in their time-management or questioning strategies. Using the GCA, STs generated more pupil time (53%) than teacher time (47%). STs at the primary level provided more technical practice, and those in secondary schools more small-sided game play. Most questions (58%) were asked during play or practice but were substantially low-order involving knowledge or recall (76%) and only 6.7% were open-ended or divergent and capable of developing tactical awareness. Conclusions: Although STs are delivering more pupil time (practice and game) than teacher-time, the lesson structure requires further fine-tuning to extend the practice task beyond technical drills. Many questions are being asked to generate knowledge about games but lack sufficient quality to enhance critical thinking and tactical awareness, as the GCA intends.

Legumes or nitrification inhibitors to reduce {N2O} emissions from subtropical cereal cropping systems in Oxisols?

The DAYCENT biogeochemical model was used to investigate how the use of fertilizers coated with nitrification inhibitors and the introduction of legumes in the crop rotation can affect subtropical cereal production and {N2O} emissions. The model was validated using comprehensive multi-seasonal, high-frequency dataset from two field investigations conducted on an Oxisol, which is the most common soil type in subtropical regions. Different N fertilizer rates were tested for each N management strategy and simulated under varying weather conditions. DAYCENT was able to reliably predict soil N dynamics, seasonal {N2O} emissions and crop production, although some discrepancies were observed in the treatments with low or no added N inputs and in the simulation of daily {N2O} fluxes. Simulations highlighted that the high clay content and the relatively low C levels of the Oxisol analyzed in this study limit the chances for significant amounts of N to be lost via deep leaching or denitrification. The application of urea coated with a nitrification inhibitor was the most effective strategy to minimize {N2O} emissions. This strategy however did not increase yields since the nitrification inhibitor did not substantially decrease overall N losses compared to conventional urea. Simulations indicated that replacing part of crop N requirements with N mineralized by legume residues is the most effective strategy to reduce {N2O} emissions and support cereal productivity. The results of this study show that legumes have significant potential to enhance the sustainable and profitable intensification of subtropical cereal cropping systems in Oxisols.

Mutations in known monogenic high bone mass loci only explain a small proportion of high bone mass cases

High bone mass (HBM) can be an incidental clinical finding; however, monogenic HBM disorders (eg, LRP5 or SOST mutations) are rare. We aimed to determine to what extent HBM is explained by mutations in known HBM genes. A total of 258 unrelated HBM cases were identified from a review of 335,115 DXA scans from 13 UK centers. Cases were assessed clinically and underwent sequencing of known anabolic HBM loci: LRP5 (exons 2, 3, 4), LRP4 (exons 25, 26), SOST (exons 1, 2, and the van Buchem's disease [VBD] 52-kb intronic deletion 3'). Family members were assessed for HBM segregation with identified variants. Three-dimensional protein models were constructed for identified variants. Two novel missense LRP5 HBM mutations ([c.518C>T; p.Thr173Met], [c.796C>T; p.Arg266Cys]) were identified, plus three previously reported missense LRP5 mutations ([c.593A>G; p.Asn198Ser], [c.724G>A; p.Ala242Thr], [c.266A>G; p.Gln89Arg]), associated with HBM in 11 adults from seven families. Individuals with LRP5 HBM ( approximately prevalence 5/100,000) displayed a variable phenotype of skeletal dysplasia with increased trabecular BMD and cortical thickness on HRpQCT, and gynoid fat mass accumulation on DXA, compared with both non-LRP5 HBM and controls. One mostly asymptomatic woman carried a novel heterozygous nonsense SOST mutation (c.530C>A; p.Ser177X) predicted to prematurely truncate sclerostin. Protein modeling suggests the severity of the LRP5-HBM phenotype corresponds to the degree of protein disruption and the consequent effect on SOST-LRP5 binding. We predict p.Asn198Ser and p.Ala242Thr directly disrupt SOST binding; both correspond to severe HBM phenotypes (BMD Z-scores +3.1 to +12.2, inability to float). Less disruptive structural alterations predicted from p.Arg266Cys, p.Thr173Met, and p.Gln89Arg were associated with less severe phenotypes (Z-scores +2.4 to +6.2, ability to float). In conclusion, although mutations in known HBM loci may be asymptomatic, they only account for a very small proportion ( approximately 3%) of HBM individuals, suggesting the great majority are explained by either unknown monogenic causes or polygenic inheritance.

Genome-wide association study of prostate cancer-specific survival

BACKGROUND: Unnecessary intervention and overtreatment of indolent disease are common challenges in clinical management of prostate cancer. Improved tools to distinguish lethal from indolent disease are critical. METHODS: We performed a genome-wide survival analysis of cause-specific death in 24,023 prostate cancer patients (3,513 disease-specific deaths) from the PRACTICAL and BPC3 consortia. Top findings were assessed for replication in a Norwegian cohort (CONOR). RESULTS: We observed no significant association between genetic variants and prostate cancer survival. CONCLUSIONS: Common genetic variants with large impact on prostate cancer survival were not observed in this study. IMPACT: Future studies should be designed for identification of rare variants with large effect sizes or common variants with small effect sizes.

Prediction of individual genetic risk to prostate cancer using a polygenic score

BACKGROUND Polygenic risk scores comprising established susceptibility variants have shown to be informative classifiers for several complex diseases including prostate cancer. For prostate cancer it is unknown if inclusion of genetic markers that have so far not been associated with prostate cancer risk at a genome-wide significant level will improve disease prediction. METHODS We built polygenic risk scores in a large training set comprising over 25,000 individuals. Initially 65 established prostate cancer susceptibility variants were selected. After LD pruning additional variants were prioritized based on their association with prostate cancer. Six-fold cross validation was performed to assess genetic risk scores and optimize the number of additional variants to be included. The final model was evaluated in an independent study population including 1,370 cases and 1,239 controls. RESULTS The polygenic risk score with 65 established susceptibility variants provided an area under the curve (AUC) of 0.67. Adding an additional 68 novel variants significantly increased the AUC to 0.68 (P = 0.0012) and the net reclassification index with 0.21 (P = 8.5E-08). All novel variants were located in genomic regions established as associated with prostate cancer risk. CONCLUSIONS Inclusion of additional genetic variants from established prostate cancer susceptibility regions improves disease prediction. Prostate 75:1467–1474, 2015. © 2015 Wiley Periodicals, Inc.

DNA looping and translocation provide an optimal cleavage mechanism for the type III restriction enzymes

EcoP15I is a type III restriction enzyme that requires two recognition sites in a defined orientation separated by up to 3.5 kbp to efficiently cleave DNA. The mechanism through which site- bound EcoP15I enzymes communicate between the two sites is unclear. Here, we use atomic force microscopy to study EcoP15I-DNA pre-cleavage complexes. From the number and size distribution of loops formed, we conclude that the loops observed do not result from translocation, but are instead formed by a contact between site- bound EcoP15I and a nonspecific region of DNA. This conclusion is confirmed by a theoretical polymer model. It is further shown that translocation must play some role, because when translocation is blocked by a Lac repressor protein, DNA cleavage is similarly blocked. On the basis of these results, we present a model for restriction by type III restriction enzymes and highlight the similarities between this and other classes of restriction enzymes.

Promoting and providing expert guidance in work-intensive clinical settings

This paper discusses how expert guidance can be best provided in work intensive clinical settings. The adequacy for supporting learning in the clinical practicum for health care disciplines is often complicated by the intensive work practices in healthcare settings. Often, clinicians' work is so intense that the scope for providing close guidance for students is quite restricted. The case advanced here draws on a range of empirical work to propose how clinician-student interactions might be optimized through the provision of a clinical ccn guided learning such as demonstrating and role-modeling. These roles can contribute in essential ways to the development of learning environments where clinicians have the opportunity to facilitate the learning of others as part of their workload, and without being burdened by the requirements of teaching and assessment processes. It differs from other approaches because although clinicians partner students and provide feedback to them, clinicians are not expected to formally assess or award a grade for student performance. Assessment and remedial action, when required, is undertaken by the role of a designated clinical supervisor qualified to perform such activities. © 2010 Springer Science+Business Media B.V.

Interprofessional education in clinical practice: Not a single vaccine

In increasingly complex health service environments, the quality of teamwork and co-operation between doctors, nurses and allied health professionals, is 'under the microscope'. Interprofessional education (IPE), a process whereby health professionals learn 'from, with and about each other', is advocated as a response to widespread calls for improved communication and collaboration between healthcare professionals. Although there is much that is commendable in IPE, the authors caution that the benefits may be overstated if too much is attributed to, or expected of, IPE activities. The authors propose that clarity is required around what can realistically be achieved. Furthermore, engagement with clinicians in the clinical practice setting who are instrumental in assisting students make sense of their knowledge through practice, is imperative for sustainable outcomes. © AHHA 2010.

Boosting morale and improving performance in the nursing setting

AIM AND BACKGROUND: While the importance of morale is well researched in the nursing literature, strategies and interventions are not so prolific. The complexities of interpersonal relationships within the clinical domain, and the critical issues faced by nurses on a daily basis, indicate that morale, job satisfaction and motivation are essential components in improving workplace efficiency, output and communication amongst staff. Drawing on educational, organizational and psychological literature, this paper argues that the ability to inspire morale in staff is a fundamental indicator of sound leadership and managerial characteristics. EVALUATION AND KEY ISSUES: Four practical concepts that could be implemented in the clinical setting are proposed. These include: role preparation for managers, understanding internal and external motivation, fostering internal motivation in nursing staff, and the importance of attitude when investing in relationships.

Julkisen tilan kontrollin ulottuvuuksia : tapaustutkimus Stop Töhryille -projektista.

Tämä tutkielma keskittyy julkisen kaupunkitilan kontrollin eri muotoihin. Ihmiset käyttävät kaupunkitilaa eri tavoin ja eri tarkoituksiin. Tilan sallitut ja kielletyt käyttömuodot ovat aina erilaisten toiveiden yhteensovittamista: yhteisen neuvottelun tulos. Tilaa myös kontrolloidaan vastaamaan erilaisia toiveita ja odotuksia. Tutkielmassa julkisen tilan kontrollin muodot on jaettu kolmeen: tilan fyysinen muokkaaminen, tilan valvonta ja asenteisiin vaikuttaminen esimerkiksi politiikkaohjelmilla. Tärkeimpänä kiinnostuksen kohteena on tilanne, jossa jokin toiminta kielletään kokonaisuudessaan. Tutkielmassa käytetään konkreettisena esimerkkinä yrityksestä kontrolloida tilaa Helsingin kaupungin Stop Töhryille -projektia: kyseessä on tapaustutkimus em. projektista. Projekti toteutettiin vuosina 1998–2008 Helsingin kaupungin rakennusviraston sekä yleisten töiden lautakunnan alaisuudessa. Projektin tavoitteena oli vähentää ja poistaa kaupunkitilassa näkyviä graffiteja. Keinoina tähän oli tekninen siivous, valvonta ja viestintä. Graffitit voidaan nähdä yhtenä keinona vallata tilaa itselle. Tutkimuksen ongelmanasettelun taustalla on pohdinta siitä, kohdistuuko julkisen tilan kontrolli jonkin tietyn toiminnon ei-toivottavuuteen vai kohdistuuko kontrolli tiettyjen toimijoiden ei-toivottavuuteen. Tavoitteena on selvittää, minkälainen tilan kontrolliin tähtäävä ohjelma Stop Töhryille -projekti oli. Tutkimuskysymykset liittyvät siihen, miksi projekti toteutettiin, mihin projektin toimenpiteet kohdistuivat ja miten nollatoleranssi määriteltiin projektissa. Tutkielman teoreettinen viitekehys pohjautuu Jock Youngin määritelmälle nollatoleranssista, nollatoleranssin kritiikille sekä Henri Lefebvren, Don Mitchellin, Andrea Sharkeyn ja Rob Shieldsin kirjoituksiin oikeudesta tilaan. Aineistona käytetään yleisten töiden lautakunnan kokousten esityslista- ja pöytäkirjamateriaalia sekä haastatteluja projektissa mukana olleille tai projektiin vaikuttaneille tahoille (N=4). Analyysin menetelmänä sovelletaan diskurssianalyysiä. Aineiston perusteella voidaan todeta, että projektissa hyödynnettiin laajasti erilaisia kontrollin keinoja. Projektin toimenpiteet keskittyivät alussa enemmän toimintoon (graffitien puhdistamiseen ja ehkäisyyn), mutta viimeisinä vuosina painopiste siirtyi enemmän toimijaan (graffitintekijään). Aineiston analyysissä yhtenä olennaisena toimijaryhmänä esille nousivat nuoret ja nuoriso, jotka mainittiin useaan otteeseen graffitintekijöinä. Tutkielmassa tätä ilmiötä pohditaan Mike Presdeen nuoruuden kriminalisointi -käsitteen sekä Zygmunt Baumanin ulossulkemisen paradigman kautta. Nollatoleranssiretoriikka on löydettävissä projektista kolmella tasolla: ideologisella, toiminnallisella sekä viestinnällisellä. Nollatoleranssia perusteltiin ideologisella tasolla rikottujen ikkunoiden teesillä: pieniä sosiaalisia häiriöitä poistamalla voidaan ehkäistä suuria rikoksia. Tämä perustelu vietiin toiminnalliselle tasolle, jossa häiriökäyttäytyjiä valvottiin ja heille vaadittiin kovia rangaistuksia. Viestinnällä pyrittiin madaltamaan kansalaisten sietokykyä graffiti-ilmiöön ja edesautettiin mahdollisimman laajan kansalais- ja asukasyhteistyön syntymistä. Lisäksi projektissa luotiin aktiivisesti tiedon ja kielen politiikkaa, joissa tuotetaan käsitystä siitä että graffitit lisäävät turvattomuutta ja konstruoidaan sellainen kieli, jossa graffitit nähdään ongelmana.
