Partnership approaches to the evaluation of complex policy initiatives: Qualitative research as key to building effective relationships

We argue that major health and social care policy initiatives are not too complex for randomised controlled trial (RCT) methodology and illustrate this using the example of the Best Services Trial (BeST? ): a RCT of an infant mental health intervention for maltreated children. We suggest that qualitative research, as a core part of the trial process from conception and development through to implementation and evaluation, is crucial in building, understanding and strengthening the partnership required to drive such a complex trial. Data pertinent to trial implementation demonstrate the iterative nature of the process whereby stakeholders are consulted and their views influence the conduct of the trial. Here we reflect on the bi-directional relationship between qualitative data collection and partnership-working in a trial. For very complex trials to be possible, significant resource needs to be available for the qualitative component. Key Practitioner Message: • Qualitative research is key to understanding, building and strengthening partnership approaches to researching complex interventions; • Qualitative research is vital to supporting randomised controlled trials involving multiple sectors; • Qualitative research provides essential explanatory power to outcome data in research.
Information System Success Disparity between Developer and Users

Background/Objectives: The purpose of this study is validating success factor perception disparity among system developer and two different system users by updated D&M (DeLone and McLean) IS (Information System) success model which has been widely studied and applied to business field by many researchers. Methods/Statistical Analysis: This research utilizes D&M model to developers who has at least one year work experience as system user, BOS (Back Office System) users and FOS (Front Office System) users to clarify disparity of IS success quality factors. For three different group analysis MSEM (Multi-group Structural Equation Model) is applied to this research to clarify quality perception disparity among groups. Findings: Since the result from MSEM analysis with 'A bank' data which has strict union regulations leading developers have at least one year user experience at front office or back office, the findings are comparable to other IS success research results especially meta-analysis. According to meta-analysis result, user satisfaction to intention to use is strong while result of this research is not significant which is supposed to be happened changing intention to use to perceived user usefulness because of mandatory system it is. Results of MSEM show perception disparities not only between developer and users but also between FOS user and BOS user. Improvements: This research proposes to development department should invest more resources not to internal service quality but information quality for FOS user, and BOS user decide the system's usefulness by information quality.

Contribution à l'amélioration de la quantification des acides nucléiques par qPCR et RT-qPCR

La qPCR est actuellement la technique de reference en matiere de quantification d'ADN. Elle peut etre definie comme une amplification exponentielle, cyclique et ciblee de la sequence d'ADN cible. Le caractere exponentiel de la qPCR est a la fois a l'origine de la sensibilite de la methode mais aussi d'une potentielle variabilite inter-echantillons. Cette variabilite est compensee par le caractere cyclique de la methode qui entraine une synchronisation de la reaction pour tous les echantillons a chaque cycle. L'amplification ciblee de la sequence choisie traduit quand a elle la specificite de la methode. Neanmoins, cette derniere propriete de la PCR reste la moins verifiee. La specificite de la qPCR est indiscutable lorsque la cible a detecter se trouve en quantite suffisante (>100 copies environ). En revanche, pour des quantites plus faibles ou en presence d'inhibiteurs, la specificite diminue ou disparait (limites de detection et de quantification). Cette perte de specificite retentit de facon significative sur la precision et la reproductibilite du dosage a realiser. Cependant, si l'hybridation non specifique est ineluctable dans ces conditions, l'amplification non specifique consecutive peut etre limitee, voire supprimee au moyen d'amorces de PCR soit plus specifiques, soit moins susceptibles de generer des differences inter-echantillons. La RT-qPCR, grâce a une etape initiale de transcription inverse (conversion d'un ARN en un ADN complementaire) permet la quantification des ARN. Cependant, la transcription inverse reste moins reproductible que la PCR, generant des differences inter-echantillons deleteres en diagnostic comme en recherche. Au cours de ces travaux, je propose des methodes originales ameliorant de facon significative differentes etapes de ces techniques. Premierement, je propose une amelioration de la standardisation de l'etape de transcription inverse capable de diminuer de facon significative la variabilite inter-echantillons ; l'utilisation d'un volume constant d'extrait d'ARN pour chaque echantillon ameliore considerablement la precision de la quantification d'ARN messagers. Deuxiemement, je propose une modification des amorces par incorporation de residus d'acides nucleiques bloques (LNA) ; cette modification permet d'augmenter la specificite des amorces aux limites de la detection. Enfin, je propose une methode simple et economique permettant la mesure directe de la temperature de fusion (Tm) dans les conditions reelles de la PCR. Ce parametre, considere comme capital pour la realisation des dosages par qPCR, est generalement obtenu par des methodes predictives peu precises. De plus, cette methode doit permettre de determiner precisement les parametres thermodynamiques des amorces (∆G, ∆H et ∆S) et ainsi avoir acces d'une part au pourcentage reel d'amorces hybridees en fonction de la temperature et d'autre part d'identifier la susceptibilite des amorces aux inhibiteurs.
Embodied Question Answering

We present a new AI task - Embodied Question Answering (EmbodiedQA) - where an agent is spawned at a random location in a 3D environment and asked a question ('What color is the car? '). In order to answer, the agent must first intelligently navigate to explore the environment, gather necessary visual information through first-person (egocentric) vision, and then answer the question ('orange'). EmbodiedQA requires a range of AI skills - language understanding, visual recognition, active perception, goal-driven navigation, commonsense reasoning, long-term memory, and grounding language into actions. In this work, we develop a dataset of questions and answers in House3D environments [1], evaluation metrics, and a hierarchical model trained with imitation and reinforcement learning.
Barriers to Further Commercialization of NFC Pilots in Western Europe

A mobile payment can be performed in various ways. For example, the Near Field Technology (NFC) integrated with mobile devices provides an opportunity of a contactless mobile payment. However, it is not only payment. The NFC can further expand functionality of mobile phones and enrich consumer experience. Indeed, added value services created by the NFC include mobile ticketing, loyalty applications, smart advertisement, informational service, physical and logical access, and other functionalities.However, despite NFC potential to create added value we cannot witness its wide penetration and global spread unless some successful solutions are implemented on a national level. The research aims to define the barriers preventing NFC pilots from entering commercialization stage in Western Europe. Commercialization of NFC mobile solutions needs to overcome a range of barriers and obstacles predefined by macro- and micro-environmental conditions, and individual factors related to consumers, which are analized in this research.
Improving Both Energy and Time Efficiency of Depth-Based Routing for Underwater Sensor Networks

Underwater Sensor Network (UWSN) is a representative three-dimensional wireless sensor network. Due to the unique characteristics of underwater acoustic communication, providing energy-efficient and low-latency routing protocols for UWSNs is challenging. Major challenges are water currents, limited resources, and long acoustic propagation delay. Network topology of UWSNs is dynamic and complex as sensors have always been moving with currents. Some proposed protocols adopt geographic routing to address this problem, but three-dimensional localization is hard to obtain in underwater environment. As depth-based routing protocol (DBR) uses depth information only which is much more easier to obtain, it is more practical for UWSNs. However, depth information is not enough to restrict packets to be forwarded within a particular area. Packets may be forwarded through multiple paths which might cause energy waste and increase end-to-end delay. In this paper, we introduce underwater time of arrival (ToA) ranging technique to address the problem above. To maintain all the original advantages of DBR, we make the following contributions: energy-efficient depth-based routing protocol that reduces redundancy energy cost in some blind zones; low-latency depth-based routing protocol that is able to deliver a packet through an optimal path. The proposed protocols are validated through extensive simulations.
Author retrospective for optimizing matrix multiply using PHiPAC: a portable high-performance ANSI C coding methodology

PHiPAC was an early attempt to improve software performance by searching in a large design space of possible implementations to find the best one. At the time, in the early 1990s, the most efficient numerical linear algebra libraries were carefully hand tuned for specific microarchitectures and compilers, and were often written in assembly language. This allowed very precise tuning of an algorithm to the specifics of a current platform, and provided great opportunity for high efficiency. The prevailing thought at the time was that such an approach was necessary to produce near-peak performance. On the other hand, this approach was brittle, and required great human effort to try each code variant, and so only a tiny subset of the possible code design points could be explored. Worse, given the combined complexities of the compiler and microarchitecture, it was difficult to predict which code variants would be worth the implementation effort. PHiPAC circumvented this effort by using code generators that could easily generate a vast assortment of very different points within a design space, and even across very different design spaces altogether. By following a set of carefully crafted coding guidelines, the generated code was reasonably efficient for any point in the design space. To search the design space, PHiPAC took a rather naive but effective approach. Due to the human-designed and deterministic nature of computing systems, one might reasonably think that smart modeling of the microprocessor and compiler would be sufficient to predict, without performing any timing, the optimal point for a given algorithm. But the combination of an optimizing compiler and a dynamically scheduled microarchitecture with multiple levels of cache and prefetching results in a very complex, highly non-linear system. Small changes in the code can cause large changes in performance, thwarting "smart" search algorithms that attempt to build models of the performance surface. PHiPAC instead used massive, diverse, offline, and only loosely informed grid or randomized search, where each point was evaluated by empirically measuring the code running on the machine, which succeeded due to its indifference to the shape of the performance surface.
Content-Aware Partial Compression for Textual Big Data Analysis in Hadoop

A substantial amount of information in companies and on the Internet is present in the form of text. The value of this semi-structured and unstructured data has been widely acknowledged, with consequent scientific and commercial exploitation. The ever-increasing data production, however, pushes data analytic platforms to their limit. Compression as an effective means to reduce data size has been employed by many emerging data analytic platforms, whom the main purpose of data compression is to save storage space and reduce data transmission cost over the network. Since general purpose compression methods endeavour to achieve higher compression ratios by leveraging data transformation techniques and contextual data, this context-dependency forces the access to the compressed data to be sequential. Processing such compressed data in parallel, such as desirable in a distributed environment, is extremely challenging. This work proposes techniques for more efficient textual big data analysis with an emphasis on content-aware compression schemes suitable for the Hadoop analytic platform. The compression schemes have been evaluated for a number of standard MapReduce analysis tasks using a collection of public and private real-world datasets. In comparison with existing solutions, they have shown substantial improvement in performance and significant reduction in system resource requirements.
Identifying High Collision Locations for Roadway Segments without Traffic Volume Information

Safety network screening is used to select road locations, such as intersections and segments, which are identified based on an abnormally high number of expected collisions or an unusually high proportion of a certain type of collisions. The most commonly used network screening method relies on rigorous safety performance functions (SPFs), which require traffic volume as an input. Many cities in Canada, including Saskatoon, currently do not collect traffic volume for every single segment within the city limits. The lack of traffic volume for a study network severely restricts the applicability of an SPF-based network screening method. On the other hand, the binomial and beta-binomial tests, which may be viewed as formal collision diagnosis tests, can be utilized to screen a roadway network, even for the roadway segments where traffic volume is unavailable. Unfortunately, previous studies that applied these two tests did not explicitly define the circumstances under which we can apply one (or both) of the tests. This study introduced a statistical test known as the 'C(? ) test' to determine when we can apply, for instance, the beta-binomial test instead of the binomial test to screen roadway networks. This study used three years' (2007-09) collision data from the City of Saskatoon to demonstrate the potential benefits of applying the collision diagnosis tests as a network screening tool. We also developed collision maps using ArcGIS to visualize the screening results, and to aid governing agencies' decision-making processes in the selection of appropriate safety countermeasures for the screened hotspots.

A DIAGNOSTIC APPROACH FOR THE DETECTION OF SPATIALLY DISTRIBUTED LOW ENERGY CONFINED RUNAWAY ELECTRONS IN THE ADITYA-U TOKAMAK BY MEANS OF SYNCHROTRON EMISSION IMAGING IN THE SUB-MILLIMETRE WAVELENGTH BAND

In recent years, the studies of Runaway Electron (RE) generation and energy dynamics in tokamaks have gained great importance from the theoretical and experimental perspective. The generation of high power RE beam during the plasma disruption may damage in-vessel components. Therefore, it is important to study and to suppress the REs for the safe operation of the large size tokamaks, such as ITER tokamak. This demands an improved, robust and sensitive RE diagnostic methods to provide essential observations of confined REs when they are in the early stage of their energy and population growth. The RE-diagnostic data can be utilized for validation of the theoretical models and also to study the efficiency of the RE mitigation techniques. Out of several RE diagnostic methods, observation of the synchrotron radiation emission (SRE) from REs is an established method to detect the confined REs and studied in the several tokamaks using the Visible and IR cameras where the lower observed energy of the REs was reported typically more than 20MeV. Signature of REs and suprathermal electrons in the cyclotron emission range is often reported from several tokamaks where the energy is in the subMeV range. Measurements of REs in the intermediate range from 0.5 MeV to 20 MeV is always been performed by the HXR and Gamma-Ray spectrometers. Non-imaging SRE measurements of the low energy REs (~2-7 MeV) performed in the FT-2 tokamak in the range of 106-156 GHz. This motivates to design a diagnostic that can detect SRE from the confined REs with the energy ~1-10 MeV in the sub-millimetre band (THz-band). The paper describes an imaging diagnostic approach proposed for the first time to capture spatiotemporally resolved SRE pattern of the low energy confined REs in the ADITYA-U tokamak. In order to design the diagnostic, a detailed forward modelling of the RE dynamics in the momentum space performed considering the experimental evolution of the plasma parameters. The simulated RE parameters were utilized to predict SRE signal level at the given detector location and the diagnostics parameters were optimized. Expected spatial distribution of the SRE brightness images as seen by the THz-camera has also been modelled. From the modelling results, it has been established that the proposed design can provide spatiotemporally resolved SRE images of the confined REs in the energy range 1-20 MeV with adequate signal to noise ratio.
Quality assessment for pre-detection diversity switching

In cellular mobile systems the on-line assessment of a radio link performance is normally associated with measurements of the received signal power, and is taken before signal demodulation. It determines the thresholds for handover policies, transmitting power control, diversity switching schemes, and other operations. However, a large received signal power does not necessarily mean "good quality" when it comes to considering radio links corrupted by cochannel interference, multipath propagation and background noise. In such cases, a better parameter that can be used to assess the signal quality is the signal-to-interference-plus-noise power ratio (SINR). Although this quality factor parameter is well-known in the literature, little has been written about how to measure it in a practical context. This article presents a method for the SINR estimation applied to a system using the Digital European Cordless Telecommunications (DECT) specification, but it can also be used by any other system employing constant modulus signals.
