The paper describes an overview of the history of development and the current state of JSC “SSC RF-IPPE” reactor research and test facility designed for assembly, research and full-scale life energy tests of space nuclear power plants with a thermionic reactor. The leading specialists involved in development and operation of this facility are represented. The most significant technological interfaces and upgrade operations carried out in the recent years are discussed. The authors consider the use of an oil-free pumping system as part of this facility during degassing and life testing. Proposed are up-to-date engineering solutions for development of the automated special measurement system designed to record NPP performance, including volt-ampere characteristics together with thermophysical and nuclear physical parameters of a ground prototype of the space nuclear power plant. Key words: reactor research and test facility, thermionic reactor, life energy tests, oil-free pumping system, automated special measurement system, volt-ampere characteristics.

Using Data

This paper reviews geodemographic classifications and developments in contemporary classifications. It develops a critique of current approaches and identifiea a number of key limitations. These include the problems associated with the geodemographic cluster label (few cluster members are typical or have the same properties as the cluster centre) and the failure of the static label to describe anything about the underlying neighbourhood processes and dynamics. To address these limitations, this paper proposed a data primitives approach. Data primitives are the fundamental dimensions or measurements that capture the processes of interest. They can be used to describe the current state of an area in a multivariate feature space, and states can be compared over multiple time periods for which data are available, through for example a change vector approach. In this way, emergent social processes, which may be too weak to result in a change in a cluster label, but are nonetheless important signals, can be captured. As states are updated (for example, as new data become available), inferences about different social processes can be made, as well as classification updates if required. State changes can also be used to determine neighbourhood trajectories and to predict or infer future states. A list of data primitives was suggested from a review of the mechanisms driving a number of neighbourhood-level social processes, with the aim of improving the wider understanding of the interaction of complex neighbourhood processes and their effects. A small case study was provided to illustrate the approach. In this way, the methods outlined in this paper suggest a more nuanced approach to geodemographic research, away from a focus on classifications and static data, towards approaches that capture the social dynamics experienced by neighbourhoods.

The Impact

The lack of a systematic definition of intermittency in the power sector blurs the use of this term in the public debate: the same power source can be described as stable or intermittent, depending on the standpoint of the authors. This work tackles a quantitative definition of intermittency adapted to the power sector, linked to the nature of the source, and not to the current state of the energy mix or the production predictive capacity. A quantitative indicator is devised, discussed and graphically depicted. A case study is illustrated by the analysis of the 2018 production data in France and then developed further to evaluate the impact of two methods often considered to reduce intermittency: aggregation and complementarity between wind and solar productions.

Abstract This case study identifies and examines interactional practices of non-directive play therapists during their therapeutic sessions with autistic adolescents. The study involved two therapists and two adolescents (siblings) on the autism spectrum. The video-recorded sessions took place at participants’ home and were conducted in Polish. Employing insights and tools from discourse-analytic approaches, in particular conversation analysis (CA), the findings show how clients and therapists are both involved in co-constructing therapeutic interactions by orienting to each other’s utterances. CA is presented in this article as a useful tool for recognizing and describing the therapists’ interactional contributions and their local functions. The therapeutic practices identified in the analysis (talk-in-practice) – e.g. mirroring, meaning expansion, recast and scaffolding – are further juxtaposed with theories concerning interactional practices in non-directive therapies (talk-in-theory) in order to provide a more detailed picture of these practices as well as complete them. The findings from this study expand the current state of knowledge of non-directive play therapies of autism spectrum disorder (ASD) and carry practical implications for specialists involved in ASD treatment.

<p>This paper introduces the methodology RWDI has developed, tested and consolidated over the years working in close collaboration with bridge designers, owners and operators, for the multi-hazard assessment of existing bridges and the ad hoc development of a structural health monitoring programme leading to enhanced resiliency. The work is highlighted through the presentation of a case study for a 2,725 m long cantilever bridge built in 1930. The dynamics of the structure in its current state were characterised and its capacity to today and future wind loading was assessed fully following the proposed methodology prior to the initiation of a structural rehabilitation program to extend the design life of the bridge beyond its 150th anniversary.</p>

Purpose The purpose of this paper is to appraise the Nigerian Economic and Financial Crimes Commission (EFCC) of their role in tackling systemic corruptions and to associate how institutional and organizational factors influence the performance of the EFCC. Design/methodology/approach Data were gathered through in-depth interviews, non-participatory observations and documentary analysis. Findings The results of the integrative analysis show that the EFCC has apparently been ineffective, and further improvization of the organization is needed. Poor performance of the EFCC was associated with factors such as lack of commitment, inefficient judiciary, insufficient budgets and incompetent personnel. Practical implications This study recommends further improvements in the form of a greater political will, improved legal process and also elevated budgetary funds and recruitment of personnel to the EFCC. Originality/value The study adopted a descriptive, qualitative case study approach to describe the current state of the EFCC in Nigeria.

Product development teams are facing continued pressure to develop more products in less time and with fewer resources. Platform-based developed is commonly seen as a solution to increase capacity of the product development pipeline. This research identified enablers and barriers to successful platform-based product development. This was achieved through a comprehensive literature review of the current state of the art and an exploratory case study of product development practices within a business-to-business environment from companies with significantly different cultures and experiences with platform-based product development. Key enablers identified in this research include institutionalizing systems engineering, development and communication of product development roadmaps, augmentation of phase gate review process and critical parameter characterization. Operational recommendations from this research are considered to be possible to implement without significant changes to existing processes and organizational structures.
