AN attempt is made here to summarize the present state of the theory of wind tunnel wall interference in a form that will be of some value to those using wind tunnels. The type of wind tunnel work frequently carried out without a complete knowledge of the corrections is also mentioned as it is of interest to those asking for, and using, wind tunnel results. A list of the most useful published reports on the subject is given at the end of the article, it is, however, by no means a complete guide to the literature of the subject, much of which is contained in academic volumes not usually available to the engineer using a wind tunnel.

The application of computational plasticity to the very practical engineering problem of crash‐worthiness of vehicle safety cab frames during impact and rollover incidents is described. The resulting behaviour of these structures cannot be determined solely by strict elastic analyses as plastic behaviour is intrinsic to the problem. The importance of predicting the deformations of the cab structure under extreme loadings lies in a consideration for the safety of its occupants. Physical testing is extremely valuable here but is costly and time‐consuming. The role of the computer is thus evident in producing rapid estimates of cab collapse modes, loadings and deformations. Three main causes of non‐linearity are identified in the behaviour of ductile framed structures under static loading, i.e. the effects of plasticity in the structural material, the effects of axial forces and the effects of large displacements of the structure under load. The paper describes and compares two computer programs which have been used to model the behaviour of vehicle cab frames when subjected to roof crush loading in a static test. Both programs employ non‐linear beam finite elements to model the behaviour of a framed structure. One program runs in an iterative fashion while the other runs in an incremental fashion.

Board faultlines, which reflect intrinsic divisions of board members into relatively homogeneous subgroups, are associated with poor firm performance. This paper aims to extend the existing board faultline research by examining how acquisition deal size moderates the negative implications of board faultlines.

This paper uses a sample of acquisitions and a quantitative research approach to conduct statistical analysis.

Using a sample of acquisitions announced between 2007 and 2016, this paper finds evidence suggesting that strong faultlines are associated with poorer acquisition outcomes in the long-term, but not in the short term. Further, this paper finds that the effect of faultline strength on long-term acquisition outcomes is weaker for larger acquisition deals than smaller acquisition deals. The findings are consistent with deal size moderating the relation between faultlines and acquisition outcomes.

This paper addresses possible endogeneity through firm fixed effects and instrumental variable analysis. Although this paper provides evidence on the moderating role of deal size in the context of faultlines, future research could examine the role of additional moderators, such as pro-diversity, trust, board leadership and board and task characteristics.

The findings suggest that boards need to be aware of situations where the negative effects of faultlines are more likely to come to the fore. For example, faultlines are more likely to play a role in more routine, obscure monitoring than for high-profile strategic decisions.

The study is multidisciplinary as it draws on the management, organizational behaviour and psychology and finance literature. It contributes to the developing literature on faultlines in several important ways. First, this paper supports their view that faultlines have adverse effects on board performance by showing that faultlines negatively impact discrete strategic investment decisions. Second, this paper provides evidence that deals size moderates the faultline-acquisition performance relation, indicating that the role of faultlines is contextual. Third, this paper finds evidence that suggests investors do not factor in board faultlines when responding to acquisition announcements.

The March issue of the Journal of Chemical Technology contains the following article, with every word of which we cordially agree. It is gratifying to find that there is one—if only one—of our scientific Journals which has the courage and the patriotism to speak out and to do so in vigorous terms. The indictment of the flabby persons belonging to the Chemical Profession who by their ineptitude and inertia are condoning the bestial crimes of the modern Huns is well‐timed and thoroughly deserved.

This paper aims to provide a holistic approach to assessing student teachers’ competence development in education for sustainable development (ESD). This is to provide evidence on which teaching and learning formats help to foster which aspects of ESD-specific professional action competence in teachers. The studied competencies consist of content knowledge (CK), pedagogical content knowledge (PCK) and the willingness to actively support and implement ESD.

A multiple case study design was used on two sequential modules of a university’s teacher education program. A mixed-methods approach was applied that combined surveys, videotaped and PhotoVoice-supported focus groups, as well as pre- and post-assessment tools. Qualitative data analysis was based on the coding paradigm of the qualitative content analysis, whereas quantitative data were interpreted by means of descriptive statistics and paired sample t-tests.

The results from this study clearly indicate that the two courses contributed to a shift in students’ non-cognitive dispositions. The study also provides evidence on the students’ competence development and demonstrates how two different learning settings support different dimensions of teachers’ professional action competence in terms of ESD.

The triangulation of data enabled not only a mere competence assessment but also deeper insights into learning processes, as well as into the drivers of and barriers to competence development. Furthermore, the study introduces an innovative approach to assessing the development of PCK.

The purpose of this paper is to update the core data set of self-neglect safeguarding adult reviews (SARs) and accompanying thematic analysis, and to address the challenge of change, exploring the necessary components beyond an action plan to ensure that findings and recommendations are embedded in policy and practice.

Further published reviews are added to the core data set from the websites of Safeguarding Adults Boards (SABs). Thematic analysis is updated using the four domains employed previously. The repetitive nature of the findings prompts questions about how to embed policy and practice change, to ensure impactful use of learning from SARs. A framework for taking forward an action plan derived from an SAR findings and recommendations is presented.

Familiar, even repetitive findings emerge once again from the thematic analysis. This level of analysis enables an understanding of both local geography and the national legal, policy and financial climate within which it sits. Such learning is valuable in itself, contributing to the evidence base of what good practice with adults who self-neglect looks like. However, to avoid the accusation that lessons are not learned, something more than a straightforward action plan to implement the recommendations is necessary. A framework is conceptualised for a strategic and longer-term approach to embedding policy and practice change.

There is still no national database of reviews commissioned by SABs so the data set reported here might be incomplete. The Care Act 2014 does not require publication of reports but only a summary of findings and recommendations in SAB annual reports. This makes learning for service improvement challenging. Reading the reviews reported here enables conclusions to be reached about issues to address locally and nationally to transform adult safeguarding policy and practice.

Answering the question “how to create sustainable change” is a significant challenge for SARs. A framework is presented here, drawn from research on change management and learning from the review process itself. The critique of serious case reviews challenges those now engaged in SARs to reflect on how transformational change can be achieved to improve the quality of adult safeguarding policy and practice.

The paper extends the thematic analysis of available reviews that focus on work with adults who self-neglect, further building on the evidence base for practice. The paper also contributes new perspectives to the process of following up SARs by using the findings and recommendations systematically within a framework designed to embed change in policy and practice.

WITH the supreme confidence of the newspaper correspondent pundit, a reader of the Daily Telegraph sent a letter which solved ‘at a stroke’ the whole problem of unemployment.

The purpose of this paper is to discuss how liberal higher education can strengthen vocational higher education.

The paper uses Shay's (2013) framework of curriculum differentiation to articulate how the strengths and shortcomings of liberal education differ from those of vocational education and to allow the differences highlighted to inform a resolution to each other's shortcomings.

There is nothing new in the findings that liberal education differs from vocational education and that both have shortcomings. What the paper presents is a viewpoint that the differences are not confirmation that these two approaches to education are in opposition but rather that they complement each other. The strength of one is the weakness of the other.

The perspective taken in this paper is developed using the language of semantic density (SD) and semantic gravity (SG). Using Shay's semantic field of recontextualized knowledge, this paper suggests that liberal and vocational education inhabit two sides of contexts and concepts continua. The paper further proposes that both are alike in a meaningful way because both have unsuccessfully managed the role of context in their curricula.

Fish quarantine is a measure to prevent the entry and spread of quarantine fish pests and diseases abroad and from one area to another within Indonesia's territory. Based on these backgrounds, this study aims to identify the knowledge, knowledge management (KM) processes and knowledge management system (KMS) priority needs for quarantine fish and other fishery products measures (QMFFP) and then develop a classification model and web-based decision support system (DSS) for QMFFP decisions.

This research methodology uses combination approaches, namely, contingency factor analysis (CFA), the cross-industry standard process for data mining (CRISP-DM) and knowledge management system development life cycle (KMSDLC). The CFA for KM solution design is performed by identifying KM processes and KMS priorities. The CRISP-DM for decision classification model is done by using a decision tree algorithm. The KMSDLC is used to develop a web-based DSS.

The highest priority requirements of KM technology for QMFFP are data mining and DSS with predictive features. The main finding of this study is to show that web-based DSS (functions and outputs) can support and accelerate QMFFP decisions by regulations and field practice needs. The DSS was developed using the CTree algorithm model, which has six main attributes and eight rules.

This study proposes a novel comprehensive framework for developing DSS (combination of CFA, CRISP-DM and KMSDLC), a novel classification model resulting from comparing two decision tree algorithms and a novel web-based DSS for QMFFP.
