The E-Business Research Network: summary of the results of the Dutch pilot survey

A project has been started with the intention to develop an E-Business Research Network on E-business related research in business and management. The initiative has been taken in co-operation between Erasmus University and UMIST to develop a project in which the first stage concerns the development of a database of researchers and their activities in e-business related research in business and management. The next stage will be to investigate the needs in companies in relation to e-business. It is hoped that an Internet-based database will stimulate interaction and communication between the supply and demand sides of e-business related research. This assumption is based on our previous research in Quality Management conducted in the early to mid 1990's. This paper describes the project and also summarises the results of the first pilot questionnaire based on responses from researchers at universities in The Netherlands

Developing a pressure ulcer risk factor minimum data set and risk assessment framework

AIM: To agree a draft pressure ulcer risk factor Minimum Data Set to underpin the development of a new evidenced-based Risk Assessment Framework.BACKGROUND: A recent systematic review identified the need for a pressure ulcer risk factor Minimum Data Set and development and validation of an evidenced-based pressure ulcer Risk Assessment Framework. This was undertaken through the Pressure UlceR Programme Of reSEarch (RP-PG-0407-10056), funded by the National Institute for Health Research and incorporates five phases. This article reports phase two, a consensus study.DESIGN: Consensus study.METHOD: A modified nominal group technique based on the Research and Development/University of California at Los Angeles appropriateness method. This incorporated an expert group, review of the evidence and the views of a Patient and Public Involvement service user group. Data were collected December 2010-December 2011.FINDINGS: The risk factors and assessment items of the Minimum Data Set (including immobility, pressure ulcer and skin status, perfusion, diabetes, skin moisture, sensory perception and nutrition) were agreed. In addition, a draft Risk Assessment Framework incorporating all Minimum Data Set items was developed, comprising a two stage assessment process (screening and detailed full assessment) and decision pathways.CONCLUSION: The draft Risk Assessment Framework will undergo further design and pre-testing with clinical nurses to assess and improve its usability. It will then be evaluated in clinical practice to assess its validity and reliability. The Minimum Data Set could be used in future for large scale risk factor studies informing refinement of the Risk Assessment Framework

“Am I also going to die, doctor?” A systematic review of the impact of in-hospital patients witnessing a resuscitation of another patient

Background: There is a growing interest in the impact of family-witnessed resuscitation. However, evidence about the effect of hospitalised patients witnessing other patients' resuscitations is limited. Aim: The aim of this systematic review is to explore the existing evidence related to the impact on patients who witness resuscitation attempts on other patients in hospital settings. Methods: The databases BNI, CINAHL, EMBASE, MEDLINE and PsycINFO were searched with the terms 'patient', 'inpatient', 'resuscitation', 'CPR', 'cardiopulmonary resuscitation' and 'witness'. The search strategy excluded the terms 'out-of-hospital', 'family' and 'relative'. The inclusion criteria were: studies related to patients exposed to a resuscitation attempt performed on another patient; quantitative and qualitative design; and physiological or psychological outcome measures. No limitations of date, language or settings were applied. Results: Five of the 540 identified studies were included: two observational studies with control groups and three qualitative studies with interviews and focus groups. Articles were published between 1968 and 2006 and were mostly rated to have a low quality of evidence. Quantitative results of the observational studies showed an increased heart rate in the study group witnessing a resuscitation (p = 0.05), increased systolic blood pressure (p < 0.01) and increased anxiety (p < 0.01). The qualitative studies highlighted the coping strategies adopted by exposed patients in response to witnessing resuscitation, including denial and dissociation. Conclusions: Our findings suggest that patients may find witnessing resuscitation to be a stressful experience. However, the evidence is sparse and mainly of poor quality. Further research is needed in order to better understand the impacts of patients witnessing a resuscitation of another patient and to identify effective support systems. © European Society of Cardiology 2017

Life satisfaction and happiness in patients shielding from the COVID-19 global pandemic:A randomised controlled study of the 'mood as information' theory

ObjectivesTo extrapolate the 'mood as information' theory to the unique and ecologically relevant setting of the COVID-19 pandemic; the specific aim was to inform health care providers of the impact of bringing the pandemic to salience during life satisfaction evaluations, assessing whether this 'prime' results in increased or decreased reports of satisfaction which are derived unconsciously.DesignProspective Randomised Interventional Study.SettingRenal Transplant Department in a tertiary centre in the United Kingdom.Participants200 Renal transplant patients aged between 20 and 88 years. Telephone interviews were undertaken between 1st May, 2020 and 29th May, 2020, at the height of 'shielding' from COVID-19.InterventionsParticipants were randomised into 2 groups, with 1 group receiving a simple 'priming question' regarding the COVID pandemic and the other group having no prior contact.Main outcome measurementsIndividuals were then asked to rate their own overall lifetime happiness; desire to change; overall life satisfaction and momentary happiness on a scale of 1 to 10 for each measure. Independent sample t-tests were used to compare results between the two groups, with a type 1 error rate below 5% considered statistically significant.ResultsParticipants' overall happiness with their life as a whole revealed that individuals who were primed with a question about COVID-19 reported increased overall happiness with their life compared to individuals who had not been primed (+0.88, 95% confidence interval 0.42 to 1.35, p = 0.0002). In addition, participants in the primed group reported less desire to change their life when compared to the non-primed group (-1.35, 95% confidence interval -2.06 to -0.65, p = 0.0002). Participants who were primed with the COVID-19 question also reported a higher overall satisfaction with their life than individuals who had not been primed (+1.01, 95% confidence interval 0.50 to 1.52, p = 0.0001). Finally, the participants who received the priming question demonstrated increased reported momentary happiness (+0.64, 95% confidence interval 0.03 to 1.24, p = 0.04).ConclusionsThe results demonstrated that bringing salience to the COVID-19 pandemic with a simple question leads to positive changes in both momentary happiness and other components of global life satisfaction, thereby extrapolating evidence for the application of the mood-as-information theory to more extreme life circumstances. Given the importance of patient-reported evaluations, these findings have implications for how, when and where accurate and reproducible measurements of life satisfaction should be obtained

A high-throughput splinkerette-PCR method for the isolation and sequencing of retroviral insertion sites

Insertional mutagens such as viruses and transposons are a useful tool for performing forward genetic screens in mice to discover cancer genes. These screens are most effective when performed using hundreds of mice, however until recently a major limitation to performing screens on this scale has been the cost effective isolation and sequencing of insertion sites. Here we present a method for the high-throughput isolation of insertion sites using a highly efficient splinkerette-PCR method coupled with capillary or 454 sequencing. This protocol includes a description of the procedure for DNA isolation, DNA digestion, linker or splinkerette ligation, primary and secondary PCR amplification, and sequencing. This method, which takes about 1 week to perform, has allowed us to isolate hundreds of thousands of insertion sites from mouse tumours and, unlike other methods, has been specifically optimised for the isolation of insertion sites generated with the murine leukaemia virus (MuLV), and can easily be performed in 96 well plate format for the efficient multiplex isolation of insertion sites

Computational and mathematical approaches to societal transitions

After an introduction of the theoretical framework and concepts of transition studies, this article gives an overview of how structural change in social systems has been studied from various disciplinary perspectives. This overview first leads to the conclusion that computational and mathematical approaches and their practical form, modeling, up till now, have been almost absent in the research and theorizing of structural change or transitions in social systems. Second, this review of the social science literature suggests numerous theoretical constructs relevant for transition modeling. Relevant concepts include the conceptualization of the micro-to-macro link, the importance of explaining both stability and change, quantitative and qualitative definitions of structural change, the use of dichotomies, synchronic and diachronic reasoning in explaining structural change, definitions of basic patterns of social change, the conceptualization of resistance to change and intentional and normative aspects of social change. This article employs these theoretical concepts to describe and discuss the models presented in this special issue in order to develop an understanding of what exactly entails a computational or mathematical approach to societal transitions

On sense and reference: examining the functional neuroanatomy of referential processing

In an event-related fMRI study, we examined the cortical networks involved in establishing. reference during language comprehension. We compared BOLD responses to sentences containing referentially ambiguous pronouns (e.g., "Ronald told Frank that he..."), referentially failing pronouns (e.g., "Rose told Emily that he...") or coherent pronouns. Referential ambiguity selectively recruited media[ prefrontal regions, suggesting that readers engaged in problemsolving to select a unique referent from the discourse model. Referential failure elicited activation increases in brain regions associated with mo rp ho -syntactic processing, and, for those readers who took failing pronouns to refer to unmentioned entities, additional regions associated with elaborative inferencing were observed. The networks activated by these two referential problems did not overlap with the network activated by a standard semantic anomaly. Instead, we observed a double dissociation, in that the systems activated by semantic anomaly are deactivated by referential ambiguity, and vice versa. This inverse coupling may reflect the dynamic recruitment of semantic and episodic processing to resolve semantically or referentially problematic situations. More generally, our findings suggest that neurocognitive accounts of language comprehension need to address not just how we parse a sentence and combine individual word meanings, but also how we determine who's who and what's what during language COmprehension.

Infrared spectroscopy of ionized corannulene in the gas phase

The gas-phase infrared spectra of radical cationic and protonated corannulene were recorded by infrared multiple-photon dissociation (IRMPD) spectroscopy using the IR free electron laser for infrared experiments. Electrospray ionization was used to generate protonated corannulene and an IRMPD spectrum was recorded in a Fourier-transform ion cyclotron resonance mass spectrometer monitoring H-loss as a function of IR frequency. The radical cation was produced by 193-nm UV photoionization of the vapor of corannulene in a 3D quadrupole trap and IR irradiation produces H, H2, and C2Hx losses. Summing the spectral response of the three fragmentation channels yields the IRMPD spectrum of the radical cation. The spectra were analyzed with the aid of quantum-chemical calculations carried out at various levels of theory. The good agreement of theoretical and experimental spectra for protonated corannulene indicates that protonation occurs on one of the peripheral C-atoms, forming an sp3 hybridized carbon. The spectrum of the radical cation was examined taking into account distortions of the C5v geometry induced by the Jahn-Teller effect as a consequence of the degenerate 2E1 ground electronic state. As indicated by the calculations, the five equivalent Cs minima are separated by marginal barriers, giving rise to a dynamically distorted system. Although in general the character of the various computed vibrational bands appears to be in order, only a qualitative match to the experimental spectrum is found. Along with a general redshift of the calculated frequencies, the IR intensities of modes in the 1000-1250 cm−1 region show the largest discrepancy with the harmonic predictions. In addition to CH "in-plane" bending vibrations, these modes also exhibit substantial deformation of the pentagonal inner ring, which may relate directly to the vibronic interaction in the radical cation

Reconstruction of primary vertices at the ATLAS experiment in Run 1 proton–proton collisions at the LHC

This paper presents the method and performance of primary vertex reconstruction in proton–proton collision data recorded by the ATLAS experiment during Run 1 of the LHC. The studies presented focus on data taken during 2012 at a centre-of-mass energy of √s=8 TeV. The performance has been measured as a function of the number of interactions per bunch crossing over a wide range, from one to seventy. The measurement of the position and size of the luminous region and its use as a constraint to improve the primary vertex resolution are discussed. A longitudinal vertex position resolution of about 30μm is achieved for events with high multiplicity of reconstructed tracks. The transverse position resolution is better than 20μm and is dominated by the precision on the size of the luminous region. An analytical model is proposed to describe the primary vertex reconstruction efficiency as a function of the number of interactions per bunch crossing and of the longitudinal size of the luminous region. Agreement between the data and the predictions of this model is better than 3% up to seventy interactions per bunch crossing

Measuring ‘Need for Recovery’ as an indicator of staff well-being in the emergency department: a survey study

No embargo required.BackgroundThe Need for Recovery (NFR) Scale is an 11-item questionnaire that assesses how work affects intershift recovery. Items are summated to form a score with a maximum value of 100. Previously reported scores range from 38 in nurses to 55 in miners. This study aimed to determine the NFR Score among ED staff and to identify whether the NFR Score was associated with characteristics potentially implicated with recovery from work.MethodsStaff in a single ED in the South West of England (annual attendances of 93 000) were asked to complete an electronic questionnaire incorporating the NFR Scale plus additional items relating to demographic, work-related and well-being characteristics, in their own time during January 2018. Descriptive statistics are presented, including median NFR Scores and associations with additional characteristics. Thematic analysis of free-text comments from an open-ended question was undertaken.ResultsOne hundred and sixty-eight responses were obtained (80.3% capture). Median NFR Score across all staff groups was 81.8 out of 100.0 (95% CI 72.7 to 81.8). Shift duration exceeding 12 hours, dissatisfaction with work–life balance and self-reported perceptions of burnout were associated with significantly elevated NFR Scores. Themes resulting from the open-ended question were ‘barriers to intershift recovery’ and ‘coping with work’.ConclusionThe NFR Scores in this study exceeded scores reported elsewhere and were associated with some demographic, occupational and well-being characteristics. The NFR Scale has utility to measure the need for intershift recovery among ED staff. A larger study is warranted to identify specific determinants of recovery and to provide recommendations.</jats:sec
