The Investigation of Corporate Manslaughter and Corporate Homicide
Get PDFThe Corporate Manslaughter and Corporate Homicide Act introduced a brand-new UK homicide offence. An organisation, such as a company, will be guilty of an offence if it causes a person’s death and this amounts to a gross breach of a relevant duty of care. The organisation’s senior management need to have also played a substantial role in the breach. Should an organisation be found guilty, the main sanction is a (potentially unlimited) fine. The offence operates in a complex investigatory and enforcement environment. There is significant overlap between corporate manslaughter and the wider health and safety regulatory regime. Only the police can investigate corporate manslaughter and only the Crown Prosecution Service (CPS) can decide whether a case will proceed. Yet the police and the CPS are reliant on enforcement bodies, such as the Health and Safety Executive, to advise in relation to whether breaches of health and safety law have occurred. Many investigations do not result in a corporate manslaughter indictment. A health and safety charge may be the only charge in circumstances where there is organisational culpability but insufficient evidence to meet the high threshold for corporate manslaughter. 29 companies have been convicted of corporate manslaughter to date
Tactical positioning in short-track speed skating: The utility of race-specific athlete-opponent interactions
Get PDFIn short-track speed skating, tactical positioning is essential for success as the race format (head-to-head) prioritises finishing position over finishing time. At present, our understanding of this phenomenon is based on measuring the similarity between athletes’ intermediate and final rankings. However, as this approach groups athlete performances across races, each lap’s estimate of tactical importance ignores the athlete-opponent interactions specific to each race. Here, we examine the utility of race-specific athlete-opponent interactions for investigating tactical positioning. Using intermediate and final rankings of elite 1,000 m short-track speed skating competitors collected from 2010/11 to 2017/18 (n = 6,196, races = 1,549), we compared the current method to a novel approach that accounted for race-specific athlete-opponent interactions. This approach first applied the current method to each race independently before using these values to form (1) discrete, empirical distributions of each lap’s tactical importance and (2) race-specific tactical positioning sequences. Our results showed that accounting for race-specific athlete-opponent interactions provided a higher measurement granularity (i.e., level of detail) for investigating tactical positioning in short-track speed skating, which better captured the complexity of the phenomenon. We observed 61 different tactical positioning behaviours and 1,269 unique tactical positioning sequences compared to the current approach’s nine-point estimates of tactical positioning importance. For this reason, we recommend that researchers and practitioners account for race-specific athlete-opponent interactions in the future as it offers a deeper understanding of tactical positioning that will enhance both strategic and tactical decisions
Not like riding a bike: How public libraries facilitate older people’s digital inclusion during the Covid-19 pandemic
Get PDFThe UK digital divide, whereby sections of society have limited use of digital technology, results in unequal access to information, knowledge, goods and services. The Covid-19 pandemic has exacerbated the push to a digital world, and this has challenged people who suffer digital exclusion, including older people, who are more likely to lack digital skills and understanding. Public libraries play a key role in tackling digital exclusion, providing digital skills training and support, and access to equipment and Wi-Fi thereby enhancing the social inclusion of marginalised groups. During the Covid-19 pandemic innovative solutions were piloted to help tackle digital exclusion and social isolation despite closure of face-to-face library interventions, particularly during lockdowns. This article explores evaluation of the Housing Plus Pilot, providing remote digital skills training and support to older people living in sheltered housing in Newcastle upon Tyne during 2021, delivered through partnership between Your Homes Newcastle, and Newcastle City Libraries. A qualitative case study approach examined a small sample of older people’s perceptions regarding the success of the pilot, and their digital literacy before and after training using semi-structured interviews via telephone. Findings showed that the pilot enabled older people to gain the necessary digital knowledge and skills required to boost confidence in becoming digitally literate citizens. Tackling digital fears and enabling them to reinforce learning through the provision of their own tablet, and free access to Wi-Fi in their sheltered housing provided a springboard for digital behaviour change. Use of a social setting in sheltered housing not only kept older people safe during socially distanced times, but also provided a supportive environment in which to learn and practice skills, together with a step-by-step training approach that focussed on the individual, which was wellsuited to this demographic
Quantitative detection of multi-frequency disturbance signal by ϕ-OTDR system
Get PDFRecently, the combination of pattern recognition technology and distributed fiber sensing systems has become increasingly common, so whether the disturbance signal can be well recovered has become increasingly important. To verify the recovery and linear response of a distributed fiber optic sensing system to multi-frequency disturbance signals, a heterodyne coherent detection system for phase-sensitive optical time-domain reflectometry is developed. The output beat signal is extracted using the digital in-phase/quadrature demodulation algorithm. The signal can be precisely located on a 7 km length range, and the disturbance signal can be restored well through the phase information. Not only the superposition signal composed of the same signal but also that composed of different kinds of signals can be successfully restored. A fast Fourier transform algorithm is used to obtain the frequency information of the superimposed signal. Combined with the use of a finite impulse response filter, the superposed signal is decomposed according to its frequency components, which perfectly restores the two signals before they are superimposed. In addition, their amplitude is highly linear with the driving voltage of the piezoelectric transducer. The system can fully retain the details of each frequency component in the recovery of multi-frequency disturbance signals. More importantly, in field experiments, the disturbance behavior is well recovered, which has broad prospects in the application of perimeter security
The value of experiments in futures and foresight science as illustrated by the case of scenario planning
Get PDFAn already pressing need to evidence the effectiveness of futures and foresight tools has been further amplified by the coronavirus pandemic, which highlighted more mainstream tools' difficulty with uncertainty. In light of this, the recent discussion in this journal on providing futures and foresight science with a stronger scientific basis is welcome. In this discussion critical realism has been proffered as a useful philosophical foundation and experiments a useful method for improving this field's scientific basis. Yet, experiments seek to isolate specific causal effects through closure (i.e., by controlling for all extraneous factors) and this may cause it to jar with critical realism's emphasis on uncertainty and openness. We therefore extend the recent discussion on improving the scientific basis of futures and foresight science by doing three things. First, we elaborate on critical realism and why the experimental method may jar with it. Second, we explain why the distinction between a conceptual and a direct replication can help overcome this jarring, meaning experiments can still be a valuable research tool for a futures and foresight science underpinned by critical realism. Third, we consider the appropriate unit of analysis for experiments on futures and foresight tools. In so doing, we situate the recent discussion on improving the scientific basis of futures and foresight science within the much longer running one on improving the scientific basis of business, management and strategy research more broadly. We use the case of scenario planning to illustrate our argument in relation to futures and foresight science
A Contactless Characterization of CNT/Epoxy Nanocomposites behavior under acid exposure
Get PDFThe use of polymer nanocomposites is ubiquitous in every industry. The high corrosion resistance and chemical durability of CNT/Epoxy nanocomposites make them suitable for chemical plants, oil industries, and hydrogen storage. However, unexpected failures have been reported for chemicals that unavoidably penetrate, provoking deterioration and degradation of the composite constituents. Conventional methods are impractical for evaluating structural health conditions because they often require disassembly of the structure and complex post-processing analysis. Contactless material characterization methods, on the other hand, are rather promising tools. Nevertheless, the influence of nanofillers and acid attack diffusion on wireless signals has yet to be explored. In this study, the effects of acid attack periods (i.e. one, week, two weeks, and month) on the scattering parameters of microstrip antennas ere investigated using a vector network analys. Additionally, an idealised multi-scale modelling approach was developed to study the influence of electrical conductivity and porosity volume changes on return loss (S11). The data showed that the diffusion of ions altered the specimen properties as time progressed. The increment in the electrical conductivity and porosity volume is reflected especially during the month-long period. Finally, in this study, it was found that wireless methods can be implemented to characterise materials which are beneficial for real-time in-situ structural health monitoring
BioMateriOME: to understand microbe-material interactions within sustainable, living architectures
No full textBioMateriOME evolved from a prototyping process which was informed from discussions between a team of designers, architects and microbiologists, when considering constructing with biomaterials or human cohabitation with novel living materials in the built environment. The prototype has two elements i) BioMateriOME-Public (BMP), an interactive public materials library, and ii) BioMateriOME-eXperimental (BMX), a replicated materials library for rigorous microbiome experimentation. The prototype was installed into the OME, a unique experimental living house, in order to 1) gain insights into society’s perceptions of living materials, and 2) perform a comparative analysis of indoor surface microbiome development on novel biomaterials in contrast to conventional indoor surfaces, respectively. This review summarises the BioMateriOME prototype and its use as a tool in combining microbiology, design, architecture and social science. The use of microbiology and biological components in the fabrication of biomaterials is provided, together with an appreciation of the microbial communities common to conventional indoor surfaces, and how these communities may change in response to the implementation of living materials in our homes. Societal perceptions of microbiomes and biomaterials, are considered within the framework of healthy architecture. Finally, features of architectural design with microbes in mind are introduced, with the possibility of codifying microbial surveillance into design and construction benchmarks, standards and regulations towards healthier buildings and their occupants
High-density genotyping reveals candidate genomic regions for chicken body size in breeds of Asian origin
Get PDFBody size is one of the main selection indices in chicken breeding. Although often investigated, knowledge of the underlying genetic mechanisms is incomplete. The aim of the current study was to identify genomic regions associated with body size differences between Asian Game and Asian Bantam type chickens. In this study, 94 and 107 chickens from four Asian Game and five Asian Bantam type breeds, respectively, were genotyped using the chicken 580K single nucleotide polymorphism (SNP) array. A genome-wide association study (GWAS) and principal component analyses (PCA) were performed to identify genomic regions associated with body size related-traits such as wing length, shank length, shank thickness, keel length, and body weight. Hierarchical clustering of genotype data showed a clear genetic difference between the investigated Asian Game and Asian Bantam chicken types. GWAS identified 16 genomic regions associated with wing length (2, FDR ≤ 0.018), shank thickness (6, FDR ≤ 0.008), keel length (5, FDR ≤ 0.023), and body weight (3, FDR ≤ 0.041). PCA showed that the first principal component (PC1) separated the two chicken types and significantly correlated with the measured body size related-traits (p ≤ 2.24e-40). SNPs contributing significantly to PC1 were subjected to a more detailed investigation. This analysis identified 11 regions potentially associated with differences in body size related-traits. A region on chromosome 4 (GGA4) (17.3 - 21.3 Mb) was detected in both analyses GWAS and PCA. This region harbors 60 genes. Among them are myotubularin 1 (MTM1) and secreted frizzled-related protein 2 (SFPR2) which can be considered as potential candidate genes for body size related-traits. Our results clearly show that the investigated Asian Game type chicken breeds are genetically different from the Asian Bantam breeds. A region on GGA4 between 17.3 and 21.3 Mb was identified which contributes to the phenotypic difference, though further validation of candidate genes is necessary
Sustainable development goals as unifying narratives in large UK firms’ Twitter discussions
Get PDFTo achieve sustainable development worldwide, the United Nations set 17 Sustainable Development Goals (SDGs) for humanity to reach by 2030. Society is involved in the challenge, with firms playing a crucial role. Thus, a key question is to what extent firms engage with the SDGs. Efforts to map firms’ contributions have mainly focused on analysing companies’ reports based on limited samples and non-real-time data. We present a novel interdisciplinary approach based on analysing big data from an online social network (Twitter) with complex network methods from statistical physics. By doing so, we provide a comprehensive and nearly real-time picture of firms’ engagement with SDGs. Results show that: (1) SDGs themes tie conversations among major UK firms together; (2) the social dimension is predominant; (3) the attention to different SDGs themes varies depending on the community and sector firms belong to; (4) stakeholder engagement is higher on posts related to global challenges compared to general ones; (5) large UK companies and stakeholders generally behave differently from Italian ones. This paper provides theoretical contributions and practical implications relevant to firms, policymakers and management education. Most importantly, it provides a novel tool and a set of keywords to monitor the influence of the private sector on the implementation of the 2030 Agenda
Evaluating Performance of Projects Using Six Sigma Approach
Get PDFResearchers have attempted to improve the project performance using principles like lean, just-in-time, total quality management, etc. However, little research is done to quantitatively assess project performance by using six sigma metrics. In this manuscript, we present weighted Rolled Throughput Yield (RTY), and hence six sigma, based methodology to evaluate the performance of projects, considering multiple criteria. Here, we consider a project decomposed into work breakdown structure of multiple levels. This approach considers seven criteria, classified under five groups namely, quality, cost, time, safety and environmental sustainability for evaluating the performance. Analytical Hierarchy Process (AHP) is used to assign weights to the criteria. RTY obtained is converted into a sigma value. The results are relevant from practical point of view since we consider various elements for performance evaluation, namely, a) complex series-parallel structure of processes in a project; b) hierarchical structure of the project; c) multiple criteria for Sigma Level (SL) computation; d) performance based on “correct first time” concept; e) flexible approach enabling the manager to add/delete the criteria depending on the need. We explain the developed methodology using two practical case studies. This is the first time that the particular six sigma metric is applied to assess the performance of construction and innovation projects. This approach is simple, lucid, yet effective, and we hope it will be useful to researchers and practicing managers alike
