Résumé :
AbstractIncreasingly, basic, translational, and clinical research has become more collaborative, resulting in multi-institutional studies that involve common approaches to a central question. For multi-institutional projects that involve recombinant or synthetic nucleic acids, Institutional Biosafety Committee (IBC) review is generally required at each separate site. Duplicative review may result in both administrative costs and delays, without evidence of increased safety or protections, and investigator frustration. To address these inefficiencies, IBC leaders drafted a collaborative IBC Reliance Authorization Agreement. The Agreement allows one or more institutions to cede IBC review to a reviewing IBC that accepts the responsibility. The ability to cede IBC review, and the ability to rely on one decision on behalf of all collaborating institutions for a given protocol, removes delays in approval of multi-center protocols, and collaborating principal investigators are able to focus on research rather than administrative tasks. In the process, we found promotion of this collaborative model led to stronger connections among institutions and among IBC members. The requirement for IBC member representation from the local community, however, limits its broader dissemination; we make several recommendations to mitigate this challenge.

Résumé :
Comparative cognitive and behavior research aims to investigate cognitive evolution by comparing performance in different species to understand how these abilities have evolved. Ideally, this requires large and diverse samples; however, these can be difficult to obtain by single labs or institutions, leading to potential reproducibility and generalization issues with small, less representative samples. To help mitigate these issues, we are establishing a multi-site collaborative Open Science approach called ManyBirds, with the aim of providing new insight into the evolution of avian cognition and behavior through large-scale comparative studies, following the lead of exemplary ManyPrimates, ManyBabies and ManyDogs projects. Here, we outline a) the replicability crisis and why we should study birds, including the origin of modern birds, avian brains and convergent evolution of cognition; b) the current state of the avian cognition field, including a ‘snapshot’ review; c) the ManyBirds project, with plans, infrastructure, limitations, implications and future directions. In sharing this process, we hope that this may be useful for other researchers in devising similar projects in other taxa, like non-avian reptiles or mammals, and to encourage further collaborations with ManyBirds and related ManyX projects. Ultimately, we hope to promote collaboration between ManyX projects to allow for wider investigation of the evolution of cognition across all animals, including potentially humans.

Résumé :
With the continuous increase in highway mileage and vehicles in China, highway accidents are also increasing year by year. However, the on-site disposal procedures of highway accidents are complex, which makes it difficult for the emergency department to fully observe the accident scene, resulting in the lack of sufficient communication and cooperation between multiple emergency departments, making the rescue efficiency low and wasting valuable rescue time, and causing unnecessary injury or loss of life due to the lack of timely assistance. Thus, this paper proposes a multi-agent-based collaborative emergency-decision-making algorithm for traffic accident on-site disposal. Firstly, based on the analysis and abstraction of highway surveillance videos obtained from the Shaanxi Provincial Highway Administration, this paper constructs an emergency disposal model based on Petri net to simulate the emergency on-site disposal procedures. After transforming the emergency disposal model into a Markov game model and applying it to the multi-agent deep deterministic strategy gradient (MADDPG) algorithm proposed in this paper, the multiple agents can optimize the emergency-decision-making and on-site disposal procedures through interactive learning with the environment. Finally, the proposed algorithm is compared with the typical algorithm and the actual processing procedure in the simulation experiment of an actual Shaanxi highway traffic accident. The results show that the proposed emergency-decision-making method could greatly improve collaboration efficiency among emergency departments and effectively reduce emergency response time. This algorithm is not only superior to other decision-making algorithms such as genetic algorithm (EA), evolutionary strategy (ES), and deep Q network (DQN), but also reduces the disposal processes by 28%, 28%, and 42%, respectively, compared with the actual disposal process in three emergency disposal cases. In summary, with the continuous development of information technology and highway management systems, the multi-agent-based collaborative emergency-decision-making algorithm will contribute to the actual emergency response process and emergency disposal in the future, improving rescue efficiency and ensuring the safety of individuals. The on-site disposal procedure of freeway accidents is complicated, and the emergency response time is limited, which makes it difficult for emergency response departments to fully observe the accident scene, leading to the lack of sufficient communication and team cooperation among multiple emergency departments. This paper proposes a multi-agent-based collaborative emergency-decision-making algorithm for traffic accident on-site disposal. Firstly, through analyzing freeway surveillance videos obtained from the Shaanxi Provincial Freeway Administration, this paper constructs an emergency disposal model based on Petri net to simulate the emergency on-site disposal procedures. Then, an emergency-decision-making method based on a multi-agent deep deterministic policy gradient algorithm is proposed to optimize the emergency-decision-making and on-site disposal procedures. Finally, the proposed algorithm is compared with the typical algorithm in a simulation experiment of an actual Shaanxi freeway traffic accident, and the difference between the proposed algorithm and the actual processing procedure is also analyzed. The results show that the proposed emergency-decision-making method could greatly improve team collaboration efficiency among emergency departments and effectively reduce emergency response time. This algorithm is not only superior to other decision-making algorithms, but also reduces the disposal processes by 28%, 28%, and 42%, respectively, compared with the actual disposal process in the three studied cases. It is believed that the continuous development of information technology and freeway management systems will help to improve actual emergency response times and emergency drills in the future.

Résumé :
Background Travel burden often substantially limits the ability of individuals to participate in clinical trials. Wide geographic dispersion of individuals with rare diseases poses an additional key challenge in the conduct of clinical trials for rare diseases. Novel technologies and methods can improve access to research by connecting participants in their homes and local communities to a distant research site. For clinical trials, however, understanding of factors important for transition from traditional multi-center trial models to local participation models is limited. We sought to test a novel, hybrid, single- and multi-site clinical trial design in the context of a trial for Juvenile Neuronal Ceroid Lipofuscinosis (CLN3 disease), a very rare pediatric neurodegenerative disorder. Methods We created a “hub and spoke” model for implementing a 22-week crossover clinical trial of mycophenolate compared with placebo, with two 8-week study arms. A single central site, the “hub,” conducted screening, consent, drug dispensing, and tolerability and efficacy assessments. Each participant identified a clinician to serve as a collaborating “spoke” site to perform local safety monitoring. Study participants traveled to the hub at the beginning and end of each study arm, and to their individual spoke site in the intervening weeks. Results A total of 18 spoke sites were established for 19 enrolled study participants. One potential participant was unable to identify a collaborating local site and was thus unable to participate. Study start-up required a median 6.7 months (interquartile range = 4.6–9.2 months). Only 33.3% (n = 6 of 18) of spoke site investigators had prior clinical trial experience, thus close collaboration with respect to study startup, training, and oversight was an important requirement. All but one participant completed all study visits; no study visits were missed due to travel requirements. Conclusions This study represents a step toward local trial participation for patients with rare diseases. Even in the context of close oversight, local participation models may be best suited for studies of compounds with well-understood side-effect profiles, for those with straightforward modes of administration, or for studies requiring extended follow-up periods.

Résumé :
Purpose A major difficulty identified many years ago in psychiatric care is the shortage of appropriate instruments with which to carry out valid and reliable therapeutic assessments which are behaviourally based and therefore appropriate for use in a variety of contexts. The aim of this project was to ascertain the utility of a forensic nursing risk assessment tool - Behavioural Status Index (BEST-Index). The paper aims to discuss these issues. Design/methodology/approach A multi-site cross-sectional survey was undertaken using mixed method design. Quantitative data was generated using BEST-Index to allow comparisons across three different levels of security (high, medium and low) in Scotland and Ireland. Qualitative data were gathered from patients and multi-disciplinary team (MDT) members using semi-structured interviews and questionnaire. Findings Measured over an 18-month period, there was a statistically significant improvement in behaviour, when comparing patients in high and medium secure hospitals. Two key themes emerged from patient and staff perspectives: “acceptance of the process” and “production and delivery of information”, respectively. The wider MDT acknowledge the value of nursing risk assessment, but require adequate information to enable them to interpret findings. Collaborating with patients to undertake risk assessments can enhance future care planning. Research limitations/implications Studies using cross-section can only provide information at fixed points in time. Practical implications The BEST-Index assessment tool is well established in clinical practice and has demonstrated good utility. Originality/value This project has served to highlight the unique contribution of BEST-Index to both staff and patients alike and confirm its robustness and versatility across differing levels of security in Scottish and Irish forensic mental health services.

Résumé :
Abstract. China is a disaster prone country. In recent years, the national functional departments have been committed to the construction of emergency surveying and mapping support capacity. However, the data owned by government departments are often systematic, accurate and authoritative, but the real-time is not enough. The improvement of data update efficiency requires a lot of resources. The main body of emergency management is also mainly government departments, which lacks public participation and interaction. The application of volunteer geographic information in China's emergency management has not yet formed a scale. This article will mainly studies the mechanism of volunteer information in emergency management, the multi-source emergency geographic information collaborative service mode with volunteer participation, and take specific engineering practices as an example to introduce the national Geographic Information Public Service Platform for Disaster Emergency, and try to solve the problems about real-time disaster site information acquisition, multi-source information online integration and collaborative services, and rapid customization and release of user-oriented emergency topics in multiple emergency scenarios Issues.

Résumé :
Introduction: The capacity of healthcare professionals to work collaboratively influences faculty and trainees’ professional identity formation, well-being, and care quality. Part of a multi-institutional project*, we created the Faculty Fellowship for Leaders in Humanistic Interprofessional Education at Boston Children’s Hospital/ Harvard Medical School. We aimed to foster trusting relationships, reflective abilities, collaboration skills, and work together to promote humanistic values within learning environments. Objective: To examine the impact of the faculty fellowship from participants’ reports of “the most important thing learned”. Methods: We studied participants’ reflections after each of 16 1½ hour fellowship sessions. Curriculum content included: highly functioning teams, advanced team formation, diversity/inclusion, values, wellbeing/renewal/burnout, appreciative inquiry, narrative reflection, and others. Responses to “What was the most important thing you learned?” were analyzed qualitatively using a positivistic deductive approach. Results: Participants completed 136 reflections over 16 sessions–77% response rate (136/176). Cohort was 91% female; mean age 52.6 (range 32-65); mean years since completion of highest degree 21.4; 64% held doctorates, 36% master’s degrees. 46% were physicians, 27% nurses, 18% social workers, 9% psychologists. 27% participated previously in a learning experience focusing on interprofessional education, collaboration or practice. Most important learning included: Relational capacities/ Use of self in relationships 96/131 (73%); Attention to values 46/131 (35%); Reflection/ Self-awareness 44/131 (34%); Fostering humanistic learning environments 21/131 (16%). Discussion: Results revealed the importance of enhancing relational capacities and use of self in relationships including handling emotions; attention to values; reflection/self-awareness and recognition of assumptions; and fostering humanistic learning environments. These topics should receive more emphasis in interprofessional faculty development programs and may help identify teaching priorities. *Supported in part by a multi-institutional grant from the Josiah Macy, Jr. Foundation (Dr. Branch as PI; Dr. Rider as site PI).

Résumé :
Addressing three current critical turns in gerontology, this article proposes the theatre as a fertile ground for various theoretical angles in age studies - including the performative on and off stage, the narrative in the script and the critical questioning of age and ageism in the multiple realities of performance. Beginning from a shared site in the theatre, researchers may be able to establish greater common ground, resulting not only in multi-disciplinary efforts but also in truly interdisciplinary work. With a foundation in performance studies, this article suggests promising directions for age studies and theatre scholarship by examining three aspects of theatrical production: a play script, Jan de Hartog’s popular The Fourposter (1951); a collaborative development of a script and production, Jeanette Mathewes Stevens’ 2010 senior drama ElderSpeak; and a performance, a 2011 song-and-dance revue staged by an established senior theatre troupe, the Sarasota Senior Theater.

Résumé :
Community collaborations have become increasingly common responses to prevent the occurrence of complex public health problems, such as violence, substance abuse, HIV/AIDS, and others. A key unanswered question is: what predicts sustainability of collaboratives? This article explores this question through a cross-site evaluation of 12 local collaboratives funded through the National Funding Collaborative on Violence Prevention (NFCVP). Conducted as longitudinal case studies, the evaluation is distinct from previous efforts in incorporating data from multiple sources. The results confirm findings from previous studies that have identified having a history of collaboration, a diverse and broad coalition, a clear vision and operation guidelines, and diversified and sufficient funding as key sustainability factors. In addition, this study has found that collaborations that are growing and expanding are more likely to have high resident involvement, a mix of professional and grassroots representation, and a facilitating, rather than direct, role in conducting prevention activities.

Résumé :
This research advocates a multi-method approach to bioarts praxis, reflexively and critically questioning the contemporary contexts that frame our engagement with nonhuman life. In doing so, the research aims to generate further community engagement with nonhuman life and the environment, and engender critical discourse on the implications of developing biotechnologies. Hegemonic institutions influence the way culture is produced and how information is constructed and understood. Habermas (1987) suggests that these institutions will inevitably influence the individual’s lifeworld as they shape lived experience through the process of systemic colonisation. I assert that this process also shapes how individuals engage with or understand nonhuman life. Through the implementation of three major projects the research aims to develop the capacity of bioarts in challenging such institutions by providing the opportunity for hands-on life science activities and real-time interactions with nonhuman life. The research by employing such methods aims to counter-act the impact of urbanised living and indifference to environmental conservation. Each aspect of the creative praxis provides a reflexive case study to establish the research aims and answer the research agenda. This includes my creative bioartworks, an art-science secondary educational course and a curated group exhibition, symposium and workshop. This research provides an alternative communicative approach to hegemonic institutions such as the mass media, scientific biotechnological industries and traditional gallery spaces (Shanken, 2011).

Résumé :
Background. La maggior parte degli studi sulla schizofrenia si è occupata pressoché esclusivamente degli esiti clinici, mentre solo pochissimi hanno indagato gli esiti dal punto di vista psicosociale ed hanno esplorato le complesse relazioni esistenti tra gli esiti e le variabili di input e di processo dell’assistenza. A tal riguardo, uno studio multicentrico europeo, l’EPSILON Study of Schizophrenia, ha avuto l’obiettivo di confrontare in cinque diversi pesi europei alcune importanti variabili psicosociali che esplorano la dimensione soggettiva degli esiti della assistenza nei pazienti schizofrenici, e di valutare come tali variabili siano a loro volta correlate con le risorse impiegate, le caratteristiche organizzative ed i pattern di utilizzazione dei servizi di salute mentale. Lo studio è stato condotto in cinque centri europei (Amsterdam, Copenaghen, Londra, Santander e Verona) con un disegno di tipo cross-sectional e le variabili di esito indagate sono state i bisogni di cura, la qualità della vita, il carico familiare e la soddisfazione nei confronti dei servizi. Scopo – Presentare i risultati emersi dalla valutazione di un campione di pazienti schizofrenici reclutati presso nel centro italiano di Verona nel corso dell’EPSILON Study. Metodo – La ricerca è stata condotta su di un campione di 107 pazienti con diagnosi ICD-10 di schizofrenia (accertata mediante la SCAN) presso il Servizio Psichiatrico Territoriale di Verona-Sud. Sono stati utilizzati i seguenti strumenti: la BPRS per la psicopatologia, la GAF per il funzionamento globale e la versioni europee della CAN per i bisogni di cura, della IEQ per il carico familiare, del LQL per la qualità della vita e della VSSS per la soddisfazione nei confronti dei servizi. I dati socio-demografici e quelli relativi all’utilizzazione del servizio sono stati ricavati dal Registro Psichiatrico dei Casi di Verona-Sud. Risultati – I pazienti reclutati nell’EPSILON Study sono risultati rappresentativi della prevalenza 1 anno di soggetti schizofrenici in carico al SPT di Verona-Sud; essi presentano nella maggior parte dei casi diagnosi di schizofrenia indifferenziata (47%) e paranoide (45%), hanno in genere un rapporto piuttosto intenso (in media 7 contatti al mese) e di lunga durata col SPT (in media 10 anni). Il campione manifesta un livello medio piuttosto basso di psicopatologia globale e nelle vari dimensioni psicopatologiche; tuttavia, sono stati rilevati sintomi di livello medio/grave negli item relativi al contenuto insolito del pensiero, ai sintomi dispercettivi, ai sintomi d’ansia ed ai sintomi depressivi in una percentuale pari rispettivamente al 19%, al 28%, al 21% ed al 18% dell’intero campione. Poco più di un terzo dei pazienti manifesta una grave compromissione del funzionamento, mentre la maggioranza del campione presenta un grado di compromissione medio/lieve. I pazienti hanno riportato in media un numero piuttosto basso di bisogni (4.75, d.s. 3.16); quelli di tipo clinico sono apparsi in genere soddisfatti, mentre quelli sociali e quelli relativi ai servizi sono apparsi per lo più privi di una risposta soddisfacente. Conclusioni - I dati della presente ricerca possono costituire un minimum data set di riferimento per analoghi studi valutativi realizzati in altri servizi di salute mentale e rappresentare allo stesso tempo la valutazione al baseline di un studio di esito da condurre nel ‘mondo reale’ dei servizi e dotato dei necessari requisiti metodologici. PAROLE CHIAVE: schizofrenia, studi multicentrici, psicopatologia, funzionamento globale, bisogni di cura
Background. Most research on the outcome of care for patients with schizophrenia generally focus on clinical variables, whereas only few studies have addressed psychosocial subjective outcomes and have explored their complex relationships with input and process variables. To fill this gap, an international multisite research, the EPSILON Study of Schizophrenia was undertaken with the aim to compare in five European countries some important psycho-social variables assessing subjective dimensions of outcome in patients with schizophrenia and to explore possible relationships with input, organizational and service utilization factors. The EPSILON Study was conducted in five European sites (Amsterdam, Copenhagen, London, Santander e Verona) with a cross-sectional design and among the variables assessed were needs for care, quality of life, family burden and satisfaction with mental health services. Objective – To provide an overall picture of the results drown from a sample of schizophrenic patients assessed in the Italian site of the EPSILON Study of Schizophrenia. Method – The study was conducted on a sample of 107 ICD-10 schizophrenic patients (diagnosed ascertained by the SCAN) receiving care from the South-Verona Community-based mental health service (CMHS). A comprehensive set of standardised instruments were used: the BPRS for measuring psychopathology, the GAF for measuring global functioning and the European versions of CAN, IEQ, LQL and VSSS for measuring respectively needs for care, family burden, quality of life and satisfaction with services. Socio-demographic and service utilisation data were extracted from the South-Verona Psychiatric Case Register. Results – Patients assessed in the frame of the EPSILON Study were representative of the one year prevalence of the schizophrenic patients on the caseloads of South-Verona CMHS; the majority of the patients had an ICD-10 diagnosis of undifferentiated (47%) or paranoid schizophrenia (45%); they tend to show a high mean number of outpatient contacts (on average 7 contacts in the last month) and a long duration of contact with the South-Verona CMHS (on average 10 years). Overall, the sample showed low mean levels of global psychopathology and in the various psychopathological dimensions; however, moderate to severe levels of psychopathology were found in BPRS items such as unusual thought content, hallucinations, anxiety and depressives symptoms for the 19%, 28%, 21% and 18% of the total sample respectively. Global functioning was severely impaired in about one third of the sample, whereas the majority of patients showed only mild to low impairment. Patients reported a low mean number of needs for care (4.75, d.s. 3.16); clinical needs were generally met, while social need and needs for services were mostly unmet. Conclusions – The present data might be seen as a reference minimum data set for similar evaluative research projects to be conducted in other mental health services across our nation, and in a meantime represent the baseline assessment for a longitudinal outcome study in the ‘real world’ of mental health services, fulfilling adequate methodological requirements.

Résumé :
AbstractA great deal of the contemporary discourse around circularity revolves around waste—the elimination of waste (and wastelands) through recycling, renewing and reuse (3Rs). In line with industrial ecological thinking, the discourse often focuses on resource efficiency and the shift toward renewables. The reconstitution of numerous previous ecologies is at most a byproduct of the deliberate design of today’s cyclic systems. Individual projects are often heralded for their innovative aspects (both high- and low-tech) and the concept has become popularly embraced in much of the Western world. Nevertheless, contemporary spatial circularity practices appear often to be detached from their particular socio-cultural and landscape ecologies. There is an emphasis on performative aspects and far too often a series of normative tools create cookie-cutter solutions that disregard locational assets—spatial as well as socio-cultural. The re-prefix is evident for developed economies and geographies, but not as obvious in the context of rapidly transforming and newly urbanizing territories. At the same time, the notion of circularity has been deeply embedded in indigenous, pre-modern and non-Western worldviews and strongly mirrored in historic constellations of urban, rural and territorial development. This contribution focuses on two contexts, Flanders in Belgium and the rural highlands, the Mekong Delta and Ho Chi Minh City in Vietnam, which reveal that in spite of the near-universal prevalence of the Western development paradigm, there are fundamentally different notions of circularity in history and regarding present-day urbanization. Historically, in both contexts, the city and its larger territory formed a social, economic and ecological unity. There was a focus is on the interdependent development of notions of circularity in the ever-evolving relations of landscape, infrastructure and urbanization. In the development of contemporary circularity, there are clear insights that can be drawn from the deep understandings of historic interdependencies and the particular mechanisms and typologies utilized. The research questions addressed are in line with territorial ecology’s call to incorporate socio-cultural and spatial dimensions when trying to understand how territorial metabolisms function (Barles, Revue D’économie Régionale and Urbaine:819–836, 2017). They are as follows: how can case studies from two seemingly disparate regions in the world inform the present-day wave of homogenized research on circularity? How can specific socio-cultural contexts, through their historical trajectories, nuance the discourse and even give insights with regard to broadened and contextualized understandings of circularity? The case studies firstly focus on past site-specific cyclic interplays between landscape, infrastructure and urbanization and their gradual dissolution into linearity. Secondly, the case studies explicitly focus on multi-year design research projects by OSA (Research Urbanism and Architecture, KU Leuven), which underscore new relations of landscape, infrastructure and urbanization and emphasize the resourcefulness of the territory itself. The design research has been elaborated in collaboration with relevant stakeholders and experts and at the request of governmental agencies.

Résumé :
This final chapter begins with a section on the history of professional development school partnerships and the current need to advance PDS and partnership research through the development of a collaborative national research agenda. The second section outlines a working framework for a core national research agenda seen as an inventive vision and tool for future empirical partnership work between researchers and teachers. The agenda is adaptable to other partnerships and involves multi-site and cross-regional partnership studies for strengthening evidence and claims of effectiveness. The focus is on the four-part K-20 partnership model: preparing new teachers, enhancing professional development, conducting meaningful collaborative research, and advancing student learning and achievement. Examples of newer research questions and a conceptual model for a research study using a quasi-experimental research approach are offered to researchers and teachers who are collaborating with one another for “re-inventing” American education and impacting policy during this new era of change.

Résumé :
The computational grid offers services for efficiently scheduling jobs on the grid, but for grid-enabled applications where data handling is a most relevant part, the data grid kicks in. It typically builds on the concept of files, sites and file transfers between sites. These use a data transfer service, plus a replica manager to keep track of where replicas are located. The authors consider a multi-site, grid-aware data warehouse, which is a large distributed repository sharing a schema and data concerning scientific or business domains. Differently from typical grid scenarios, the data warehouse is not simply a set of files and accesses to individual files. It is a single distributed schema and both localized and distributed computations must be managed over that schema. Given this difference, it is important to study approaches for placement and computation over the grid data warehouse and this is our contribution in this book chapter.

Résumé :
The computational grid offers services for efficiently scheduling jobs on the grid, but for grid-enabled applications where data handling is a most relevant part, the data grid kicks in. It typically builds on the concept of files, sites and file transfers between sites. These use a data transfer service, plus a replica manager to keep track of where replicas are located. The authors consider a multi-site, grid-aware data warehouse, which is a large distributed repository sharing a schema and data concerning scientific or business domains. Differently from typical grid scenarios, the data warehouse is not simply a set of files and accesses to individual files. It is a single distributed schema and both localized and distributed computations must be managed over that schema. Given this difference, it is important to study approaches for placement and computation over the grid data warehouse and this is our contribution in this book chapter.

Résumé :
This chapter draws empirical findings from a larger study that compared principals' leadership across three different international cultural contexts (Hong Kong, Singapore and Perth, Australia) and explored the influence of culture on leadership. Data were collected using interviews and structured vignettes from a purposive sample of 21 principals across three different cultures and were analyzed to arrive at a set of site-specific and cross-cultural comparative propositions. One set of these propositions is reported in the chapter. Societal culture was found to act as a filter and mediator to create substantial differences in leadership behaviors relevant to collaboration. The paper suggests re-thinking in the preparation, training, hiring and selection, of principals, all of which – given multi-ethnic, diverse societies – require more culturally aware and sensitive policies and practices.

Résumé :
The change in any instructional practice requires an effective professional development plan that best addresses the needs of the teachers. This chapter is an attempt to conceptualize a research-based multi-dimensional model for professional development of teachers with respect to technology integration. The purpose of this study was to use the current literature to determine the characteristics of high quality professional development that focuses on the integration of instructional technology into teaching practices. This study developed as a result of the findings and recommendations from a previous quasi-experimental study. Following a thorough review of related literature to illuminate the recommended professional development practices, a model was developed based on the TPACK framework. The proposed model includes (1) TPACK as the central framework to design the teacher technology integration curricula, (2) the use of online discussion and support platforms to ensure the sustainability component of the training, and (3) on-site professional collaboration and partnership to provide teachers with opportunities to model, share their experiences.

Résumé :
Because outsourcing and offshoring operations entail multi-site operations and inter-organizational alliances, they require effective boundary-spanning partnerships: inter-divisional, inter-organizational, and often, multi-country partnerships. This paper reports a multi-discipline research study—involving engineering, anthropology and telecommunications elements—on dispersed global engineering design teams. A framework involving power, culture, and collaborative activity is introduced. The focus here is on power and communications issues. Co-oriented, collaborative project activity is achieved when power issues are neutralized. When sub-team members perceive inequity, they frequently respond adversely. They may purposely create miscommunications among sub-teams, covertly subvert project goals, or otherwise act in ways that reduce project performance. Outsourcing of engineering design operations is a major challenge for the engineering profession. Outsourcing activity to India and China has increased; educational systems in these countries both improve in quality and augment the quantity of engineers produced. Traditional engineering skills are swiftly becoming a commodity in the global market.

Résumé :
Abstract Discuss a cost-effective rigless methodology to abandon complex onshore wells. – Onshore wells can be near housing, and multiple non-technical risks (NTR) need to be carefully managed to keep the license to operate. – Select a 100% electric rigless plug and abandonment (P&A) unit to reduce emissions, smell, and noise contour. – Manage and execute a complex P&A scope of work of 60+ wells in three years. This paper studies the solutions selected and implemented by the project management team in collaboration with the well operator for a successful start-up and cost-effective well abandonment project. – Implement the first fully integrated well abandonment project solution for onshore P&A in the Netherlands including well P&A services, hydraulic workover (HWO), logistics, and site preparation. – Ensure full compliance with the stringent local mining and environmental regulations. – Select a bespoke P&A unit to provide a robust solution for complex P&A work. – Select downhole services and technologies to successfully execute a complex, rigless P&A work scope. The project encompasses over 60 wells on 23 different onshore locations drilled over a 50 year period. The known scope of work and requirements of multiple contingencies while managing NTRs resulted in the selection of a rigless well abandonment solution. – A modular, highly capable rigless well abandonment unit in combination with enabling downhole technologies provides a total solution for simple and complex wells. – A 100-percent electrically powered P&A unit reduces emissions, smell, and noise contour. This was thefirst electrified P&A unit in the history of the operator running on grid power. All well site equipment is electrically powered (HWO P&A Unit, Mud/Cement Pumps, and ancillary equipment) to reduce emissions, smell, and noise contour. – Project management and engineering is key to ensuring efficient planning and close collaboration with the well operator's project team. – Collaboration between partners enables multi-skilling and reduction of POB to save additional costs. – Improve efficiencies and execution through extensive after-action reviews and learning curves. – Successfully execute complex P&A work and re-establish annular cement integrity on multiple complex wells (perforate, wash and cement, section milling, perf, circulate and cement) – More than 40 wells completed in two years, and operations continue today. – This is the first fully integrated well abandonment approach that includes full project management, well-site supervision, cross-product services, and extensive third-party management (HWO, logistics, and other third-party service companies). – A 100% electric P&A unit reduces emissions, smell, and noise contour, delivering a net reduction of CO2 through electrification.

Résumé :
The overall frame of this research was the governance process of surface water resources in Latvia, particularly, public lakes, to be studied by applying triple dimensional governance framing model of complementary dimensions of governance stakeholders, governance content and governance instruments. Studies were realized in the area of Lake Lubans, administratively located on the border areas between two municipalities of Madona and Rezekne in the eastern part of the country. Lake Lubans is the largest lake in Latvia, as well as the largest dammed lake in Europe, included in surrounding NATURA 2000 nature reserve territory as also nationally largest inland protected wetland complex (Lubana Wetland/Ramsar site, 2009). Case Study Research methodology was applied by approaching the study area not only as a nature protection area but especially as a socio-ecological territorial and human system, using indepth semi-structured interviews in the surrounding areas/administrative territories with all main local-regional and also national stakeholder groups, as well as, applying document studies and territorial/objects’ observations. The National Nature Protection Agency’s Latgale region branch as the legal administrator supervises all nature protection territories in the region and also the Lubana Wetland, which is still lacking statutory Nature Protection Plan for the area; and, due to very limited administrative capacities, Agency is to be oriented more towards c ooperation with various other national and regional institutions from very different sectors, being organized under mainly two ministries involved – Environmental and Regional Development Ministry (nature, environmental, municipal and regional development sectors) and Agriculture Ministry (agriculture, forestry, fisheries, water infrastructure sectors), as well as, particularly, with many municipalities in the wetland area. But municipalities have to take into account also interests of local communities, the basic socio-economic development situation and possibilities, having also limited capacities, sometimes also approaches, which all is to be combined with strong nature protection requirements and limitations. This governance landscape requires co-relation of various and diverse interests and creates a rather fragmented and underdeveloped management of the lake. Lake water levels are fully regulated by the national Water infrastructure agency using dams and other hydro-technical systems, while water areas are used not only for highly popular angling, but also for active commercial fishing and various recreational activities, tourism, esp. bird watching etc., thus also keeping strong nature protection status in the same time, which all represent a unique challenge for to be developed multi-stakeholders and socioecological system (SES) approach for lake governance (assessment, planning, collaborative management, monitoring, and communication) developments in Latvia and alike.

Dans ASME 2016 International Design Engineering Technical Conferences and Computers and Information in Engineering Conference. American Society of Mechanical Engineers, 2016. http://dx.doi.org/10.1115/detc2016-60244.

Résumé :
A variable ratio gearbox (VRG) provides discrete variable rotor speed operation, and thus increases wind capture, for small fixed-speed wind turbines. It is a low-cost, reliable alternative to conventional variable speed operation, which requires special power-conditioning equipment. The authors’ previous work has demonstrated the benefit of using a VRG in a fixed-speed system with passive blades. This work characterizes the performance of the VRG when used with active blades. The main contribution of the study is an integrative design framework that maximizes power production while mitigating stress in the blade root. As part of the procedure, three gear ratios are selected for the VRG. It establishes the control rules by defining the gear ratio and pitch angle used in relation to wind speed and mechanical torque. A 300 kW wind turbine model is used for a case study that demonstrates how the framework is implemented. The model consists of aerodynamic, mechanical, and electrical submodels, which work collaboratively to convert kinetic air to electrical power. Blade element momentum theory is used in the aerodynamic model to compute the blade loads. The resulting torque is passed through a mechanical system and subsequently to the induction machine model to generate power. The BEM method also provides the thrust and bending loads that contribute to blade-root stress. The stress in the root of the blade is also computed in response to these loads, as well as those caused by gravity and centrifugal force. Two case studies are performed using wind data that was obtained from the National Renewable Energy Laboratory (NREL). Each of these represents an installation site with a unique set of wind conditions that are used to customize the wind turbine design. The framework uses dynamic programming to simulate the performance of an exhaustive set of combinations. Each combination is evaluated over each set of recorded wind data. The combinations are evaluated in terms of the total energy and stress that is produced over the simulation period. Weights are applied to a multi-objective cost function that identifies the optimal design configurations with respect to the design objectives. As a final design step, a VRG combination is selected, and a control algorithm is established for each set of wind data. During operation, the cost function can also be used to bias the system towards higher power production or lower stress. The results suggest a VRG can improve wind energy production in Region 2 by roughly 10% in both the low and high wind regions. In both cases, stress is also increased in Region 2, as the power increases. However, the stress in Region 3 may be reduced for some wind speeds through the optimal selection of gear combinations.

Texte intégral
Résumé :
The main recommendations of the panel report can be summarised under four headings: 1. From Source to Sea: River systems, from their source to the sea and beyond, should form the focus for research projects, allowing the integration of all archaeological work carried out along their course. Future research should take a holistic view of the marine and maritime historic environment, from inland lakes that feed freshwater river routes, to tidal estuaries and out to the open sea. This view of the landscape/seascape encompasses a very broad range of archaeology and enables connections to be made without the restrictions of geographical or political boundaries. Research strategies, programmes From Source to Sea: ScARF Marine and Maritime Panel Report iii and projects can adopt this approach at multiple levels; from national to site-specific, with the aim of remaining holistic and cross-cutting. 2. Submerged Landscapes: The rising research profile of submerged landscapes has recently been embodied into a European Cooperation in Science and Technology (COST) Action; Submerged Prehistoric Archaeology and Landscapes of the Continental Shelf (SPLASHCOS), with exciting proposals for future research. Future work needs to be integrated with wider initiatives such as this on an international scale. Recent projects have begun to demonstrate the research potential for submerged landscapes in and beyond Scotland, as well as the need to collaborate with industrial partners, in order that commercially-created datasets can be accessed and used. More data is required in order to fully model the changing coastline around Scotland and develop predictive models of site survival. Such work is crucial to understanding life in early prehistoric Scotland, and how the earliest communities responded to a changing environment. 3. Marine & Maritime Historic Landscapes: Scotland’s coastal and intertidal zones and maritime hinterland encompass in-shore islands, trans-continental shipping lanes, ports and harbours, and transport infrastructure to intertidal fish-traps, and define understanding and conceptualisation of the liminal zone between the land and the sea. Due to the pervasive nature of the Marine and Maritime historic landscape, a holistic approach should be taken that incorporates evidence from a variety of sources including commercial and research archaeology, local and national societies, off-shore and onshore commercial development; and including studies derived from, but not limited to history, ethnology, cultural studies, folklore and architecture and involving a wide range of recording techniques ranging from photography, laser imaging, and sonar survey through to more orthodox drawn survey and excavation. 4. Collaboration: As is implicit in all the above, multi-disciplinary, collaborative, and cross-sector approaches are essential in order to ensure the capacity to meet the research challenges of the marine and maritime historic environment. There is a need for collaboration across the heritage sector and beyond, into specific areas of industry, science and the arts. Methods of communication amongst the constituent research individuals, institutions and networks should be developed, and dissemination of research results promoted. The formation of research communities, especially virtual centres of excellence, should be encouraged in order to build capacity.

Hall, Mark, et Neil Price. Medieval Scotland : A Future for its Past. Society of Antiquaries of Scotland, septembre 2012. http://dx.doi.org/10.9750/scarf.09.2012.165.

Texte intégral
Résumé :
The main recommendations of the panel report can be summarised under five key headings. Underpinning all five areas is the recognition that human narratives remain crucial for ensuring the widest access to our shared past. There is no wish to see political and economic narratives abandoned but the need is recognised for there to be an expansion to more social narratives to fully explore the potential of the diverse evidence base. The questions that can be asked are here framed in a national context but they need to be supported and improved a) by the development of regional research frameworks, and b) by an enhanced study of Scotland’s international context through time. 1. From North Britain to the Idea of Scotland: Understanding why, where and how ‘Scotland’ emerges provides a focal point of research. Investigating state formation requires work from Medieval Scotland: a future for its past ii a variety of sources, exploring the relationships between centres of consumption - royal, ecclesiastical and urban - and their hinterlands. Working from site-specific work to regional analysis, researchers can explore how what would become ‘Scotland’ came to be, and whence sprang its inspiration. 2. Lifestyles and Living Spaces: Holistic approaches to exploring medieval settlement should be promoted, combining landscape studies with artefactual, environmental, and documentary work. Understanding the role of individual sites within wider local, regional and national settlement systems should be promoted, and chronological frameworks developed to chart the changing nature of Medieval settlement. 3. Mentalities: The holistic understanding of medieval belief (particularly, but not exclusively, in its early medieval or early historic phase) needs to broaden its contextual understanding with reference to prehistoric or inherited belief systems and frames of reference. Collaborative approaches should draw on international parallels and analogues in pursuit of defining and contrasting local or regional belief systems through integrated studies of portable material culture, monumentality and landscape. 4. Empowerment: Revisiting museum collections and renewing the study of newly retrieved artefacts is vital to a broader understanding of the dynamics of writing within society. Text needs to be seen less as a metaphor and more as a technological and social innovation in material culture which will help the understanding of it as an experienced, imaginatively rich reality of life. In archaeological terms, the study of the relatively neglected cultural areas of sensory perception, memory, learning and play needs to be promoted to enrich the understanding of past social behaviours. 5. Parameters: Multi-disciplinary, collaborative, and cross-sector approaches should be encouraged in order to release the research potential of all sectors of archaeology. Creative solutions should be sought to the challenges of transmitting the importance of archaeological work and conserving the resource for current and future research.

Résumé :
This report is one of a series of reports documenting the methods and findings of a multi-year, multi-disciplinary project coordinated by the Pacific Earthquake Engineering Research Center (PEER) and funded by the California Earthquake Authority (CEA). The overall project is titled “Quantifying the Performance of Retrofit of Cripple Walls and Sill Anchorage in Single-Family Wood-Frame Buildings,” henceforth referred to as the “PEER–CEA Project.” The overall objective of the PEER–CEA Project is to provide scientifically based information (e.g., testing, analysis, and resulting loss models) that measure and assess the effectiveness of seismic retrofit to reduce the risk of damage and associated losses (repair costs) of wood-frame houses with cripple wall and sill anchorage deficiencies as well as retrofitted conditions that address those deficiencies. Tasks that support and inform the loss-modeling effort are: (1) collecting and summarizing existing information and results of previous research on the performance of wood-frame houses; (2) identifying construction features to characterize alternative variants of wood-frame houses; (3) characterizing earthquake hazard and ground motions at representative sites in California; (4) developing cyclic loading protocols and conducting laboratory tests of cripple wall panels, wood-frame wall subassemblies, and sill anchorages to measure and document their response (strength and stiffness) under cyclic loading; and (5) the computer modeling, simulations, and the development of loss models as informed by a workshop with claims adjustors. This report is a product of Working Group 3 (WG3), Task 3.1: Selecting and Scaling Ground-motion records. The objective of Task 3.1 is to provide suites of ground motions to be used by other working groups (WGs), especially Working Group 5: Analytical Modeling (WG5) for Simulation Studies. The ground motions used in the numerical simulations are intended to represent seismic hazard at the building site. The seismic hazard is dependent on the location of the site relative to seismic sources, the characteristics of the seismic sources in the region and the local soil conditions at the site. To achieve a proper representation of hazard across the State of California, ten sites were selected, and a site-specific probabilistic seismic hazard analysis (PSHA) was performed at each of these sites for both a soft soil (Vs30 = 270 m/sec) and a stiff soil (Vs30=760 m/sec). The PSHA used the UCERF3 seismic source model, which represents the latest seismic source model adopted by the USGS [2013] and NGA-West2 ground-motion models. The PSHA was carried out for structural periods ranging from 0.01 to 10 sec. At each site and soil class, the results from the PSHA—hazard curves, hazard deaggregation, and uniform-hazard spectra (UHS)—were extracted for a series of ten return periods, prescribed by WG5 and WG6, ranging from 15.5–2500 years. For each case (site, soil class, and return period), the UHS was used as the target spectrum for selection and modification of a suite of ground motions. Additionally, another set of target spectra based on “Conditional Spectra” (CS), which are more realistic than UHS, was developed [Baker and Lee 2018]. The Conditional Spectra are defined by the median (Conditional Mean Spectrum) and a period-dependent variance. A suite of at least 40 record pairs (horizontal) were selected and modified for each return period and target-spectrum type. Thus, for each ground-motion suite, 40 or more record pairs were selected using the deaggregation of the hazard, resulting in more than 200 record pairs per target-spectrum type at each site. The suites contained more than 40 records in case some were rejected by the modelers due to secondary characteristics; however, none were rejected, and the complete set was used. For the case of UHS as the target spectrum, the selected motions were modified (scaled) such that the average of the median spectrum (RotD50) [Boore 2010] of the ground-motion pairs follow the target spectrum closely within the period range of interest to the analysts. In communications with WG5 researchers, for ground-motion (time histories, or time series) selection and modification, a period range between 0.01–2.0 sec was selected for this specific application for the project. The duration metrics and pulse characteristics of the records were also used in the final selection of ground motions. The damping ratio for the PSHA and ground-motion target spectra was set to 5%, which is standard practice in engineering applications. For the cases where the CS was used as the target spectrum, the ground-motion suites were selected and scaled using a modified version of the conditional spectrum ground-motion selection tool (CS-GMS tool) developed by Baker and Lee [2018]. This tool selects and scales a suite of ground motions to meet both the median and the user-defined variability. This variability is defined by the relationship developed by Baker and Jayaram [2008]. The computation of CS requires a structural period for the conditional model. In collaboration with WG5 researchers, a conditioning period of 0.25 sec was selected as a representative of the fundamental mode of vibration of the buildings of interest in this study. Working Group 5 carried out a sensitivity analysis of using other conditioning periods, and the results and discussion of selection of conditioning period are reported in Section 4 of the WG5 PEER report entitled Technical Background Report for Structural Analysis and Performance Assessment. The WG3.1 report presents a summary of the selected sites, the seismic-source characterization model, and the ground-motion characterization model used in the PSHA, followed by selection and modification of suites of ground motions. The Record Sequence Number (RSN) and the associated scale factors are tabulated in the Appendices of this report, and the actual time-series files can be downloaded from the PEER Ground-motion database Portal (https://ngawest2.berkeley.edu/)(link is external).
