The link between family orientation, strategy and innovation in Dutch SMEs: a longitudinal study

This study aimed at identifying some of the factors determining innovation performance in the SME. Based on a sample of 388 Dutch SME's, hypotheses were tested in particular regarding the main effects of strategy, and the direct and indirect efects of family orientation on firm performance. The results clearly support a relationship between different components of strategy and strategic process and innovation performance, even on a longitudinal basis of�up to four years.�

Family Orientation, Strategic Orientation and Innovation Performance in SMEs: A Test of Lagged Effects

Past research suggests a negative effect of family orientation on innovation performance. However, many past studies have certain limitations that this study is designed to overcome. In particular,this study estimates lagged effects of family orientation on innovation performance while controlling for organization context variables and the mediating effect of strategic orientation. It also uses a multidimensional approach to measure family orientation while testing for common method bias. This study makes use of a sample of 343 Dutch small and medium size firms. Innovation performance, being the dependent variable, was collected in 2005. All independent variables, i.e. strategy, family orientation and context variables, are collected in previous time periods, with lags ranging between 3 and 4 years. Family orientation is measured according to five independent dimensions including family power, family culture,overlap of ownership and management and intentions to keep the firm in the family.

Family orientation, strategy and organizational learning as predictors of knowledge management in Dutch SMEs

Knowledge management (KM) is becoming a growing concern in management research and practice because of its role in determining firm innovation capability and in enhancing working life quality of knowledge workers. Although research and policy interest in KM is beginning to grow for small and medium-sized suppliers, still relatively limited attention has been paid to understand the specifics of KM issues of SMEs in particular. Previous studies rely on either qualitative case studies or very small samples. In this study, we will investigate KM among SMEs using empirical data from about 2000 SMEs. The aim of this study is to investigate the prevalence of different KM techniques and the determinants of KM. We found that SMEs are most likely to acquire knowledge by staying in touch with professionals and experts outside the company. Also, SMEs are most likely to share knowledge and experience by talking to each other and to store knowledge in formal repositories. Furthermore, we found a significant positive relationship between organizational learning and strategy and knowledge management, as well as a significant negative relationship between family orientation and knowledge management. In conclusion, knowledge management practices are not independent from other resources and processes inside SMEs. Therefore, there is no all-in-one knowledge management practices package for all types of SMEs across industries.

Measuring business dynamics among incumbent firms in The Netherlands

Business dynamics in an industry is generally seen as an important indicator of the industry's level of competitiveness and economic performance. Two types of business dynamics may be distinguished: business dynamics reflecting competition by new-firm entries and business dynamics reflecting competition among incumbent firms. A growing literature pays attention to the important role of the former type of business dynamics (the starting up of new firms) for achieving economic growth. However, the latter type of business dynamics tends to be overlooked in this type of literature. In part this is due to the large requirements, both in terms of data and in terms of methodology, of measuring competition among incumbent firms. A sophisticated indicator for measuring the extent of business dynamics among incumbent firms in an industry is the mobility index. In the current paper we compute mobility indices for 16 industries -covering the whole private sector except for the primary sectors of economy- in the Netherlands over the period 2000-2006, and compare the values of the mobility indices across the sectors.

A Prediction Model for Successful Increase of Adalimumab Dose Intervals in Patients with Crohn’s Disease:Secondary Analysis of the Pragmatic Open-Label Randomised Controlled Non-inferiority LADI Trial

Background: In the pragmatic open-label randomised controlled non-inferiority LADI trial we showed that increasing adalimumab (ADA) dose intervals was non-inferior to conventional dosing for persistent flares in patients with Crohn’s disease (CD) in clinical and biochemical remission. Aims: To develop a prediction model to identify patients who can successfully increase their ADA dose interval based on secondary analysis of trial data. Methods: Patients in the intervention group of the LADI trial increased ADA intervals to 3 and then to 4 weeks. The dose interval increase was defined as successful when patients had no persistent flare (&gt; 8 weeks), no intervention-related severe adverse events, no rescue medication use during the study, and were on an increased dose interval while in clinical and biochemical remission at week 48. Prediction models were based on logistic regression with relaxed LASSO. Models were internally validated using bootstrap optimism correction. Results: We included 109 patients, of which 60.6% successfully increased their dose interval. Patients that were active smokers (odds ratio [OR] 0.90), had previous CD-related intra-abdominal surgeries (OR 0.85), proximal small bowel disease (OR 0.92), an increased Harvey-Bradshaw Index (OR 0.99) or increased faecal calprotectin (OR 0.997) were less likely to successfully increase their dose interval. The model had fair discriminative ability (AUC = 0.63) and net benefit analysis showed that the model could be used to select patients who could increase their dose interval. Conclusion: The final prediction model seems promising to select patients who could successfully increase their ADA dose interval. The model should be validated externally before it may be applied in clinical practice. Clinical Trial Registration Number: ClinicalTrials.gov, number NCT03172377.</p

Copy number variants as modifiers of breast cancer risk for BRCA1/BRCA2 pathogenic variant carriers

The risk of germline copy number variants (CNVs) in BRCA1 and BRCA2 pathogenic variant carriers in breast cancer is assessed, with CNVs overlapping SULT1A1 decreasing breast cancer risk in BRCA1 carriers.The contribution of germline copy number variants (CNVs) to risk of developing cancer in individuals with pathogenic BRCA1 or BRCA2 variants remains relatively unknown. We conducted the largest genome-wide analysis of CNVs in 15,342 BRCA1 and 10,740 BRCA2 pathogenic variant carriers. We used these results to prioritise a candidate breast cancer risk-modifier gene for laboratory analysis and biological validation. Notably, the HR for deletions in BRCA1 suggested an elevated breast cancer risk estimate (hazard ratio (HR) = 1.21), 95% confidence interval (95% CI = 1.09-1.35) compared with non-CNV pathogenic variants. In contrast, deletions overlapping SULT1A1 suggested a decreased breast cancer risk (HR = 0.73, 95% CI 0.59-0.91) in BRCA1 pathogenic variant carriers. Functional analyses of SULT1A1 showed that reduced mRNA expression in pathogenic BRCA1 variant cells was associated with reduced cellular proliferation and reduced DNA damage after treatment with DNA damaging agents. These data provide evidence that deleterious variants in BRCA1 plus SULT1A1 deletions contribute to variable breast cancer risk in BRCA1 carriers.Peer reviewe

Identification of Surgeon Burnout via a Single-Item Measure

BackgroundBurnout is endemic in surgeons in the UK and linked with poor patient safety and quality of care, mental health problems, and workforce sustainability. Mechanisms are required to facilitate the efficient identification of burnout in this population. Multi-item measures of burnout may be unsuitable for this purpose owing to assessment burden, expertise required for analysis, and cost.AimsTo determine whether surgeons in the UK reporting burnout on the 22-item Maslach Burnout Inventory (MBI) can be reliably identified by a single-item measure of burnout.MethodsConsultant (n = 333) and trainee (n = 217) surgeons completed the MBI and a single-item measure of burnout. We applied tests of discriminatory power to assess whether a report of high burnout on the single-item measure correctly classified MBI cases and non-cases.ResultsThe single-item measure demonstrated high discriminatory power on the emotional exhaustion burnout domain: the area under the curve was excellent for consultants and trainees (0.86 and 0.80), indicating high sensitivity and specificity. On the depersonalisation domain, discrimination was acceptable for consultants (0.76) and poor for trainees (0.69). In contrast, discrimination was acceptable for trainees (0.71) and poor for consultants (0.62) on the personal accomplishment domain.ConclusionsA single-item measure of burnout is suitable for the efficient assessment of emotional exhaustion in consultant and trainee surgeons in the UK. Administered regularly, such a measure would facilitate the early identification of at-risk surgeons and swift intervention, as well as the monitoring of group-level temporal trends to inform resource allocation to coincide with peak periods

Burnout Among Surgeons in the UK During the COVID-19 Pandemic: A Cohort Study

BackgroundSurgeon burnout has implications for patient safety and workforce sustainability. The aim of this study was to establish the prevalence of burnout among surgeons in the UK during the COVID-19 pandemic.MethodsThis cross-sectional online survey was set in the UK National Health Service and involved 601 surgeons across the UK of all specialities and grades. Participants completed the Maslach Burnout Inventory and a bespoke questionnaire. Outcome measures included emotional exhaustion, depersonalisation and low personal accomplishment, as measured by the Maslach Burnout Inventory-Human Services Survey (MBI-HSS).ResultsA total of 142 surgeons reported having contracted COVID-19. Burnout prevalence was particularly high in the emotional exhaustion (57%) and depersonalisation (50%) domains, while lower on the low personal accomplishment domain (15%). Burnout prevalence was unrelated to COVID-19 status; however, the greater the perceived impact of COVID-19 on work, the higher the prevalence of emotional exhaustion and depersonalisation. Degree of worry about contracting COVID-19 oneself and degree of worry about family and friends contacting COVID-19 was positively associated with prevalence on all three burnout domains. Across all three domains, burnout prevalence was exceptionally high in the Core Trainee 1–2 and Specialty Trainee 1–2 grades.ConclusionsThese findings highlight potential undesirable implications for patient safety arising from surgeon burnout. Moreover, there is a need for ongoing monitoring in addition to an enhanced focus on mental health self-care in surgeon training and the provision of accessible and confidential support for practising surgeons

TRPM2 channel-mediated cell death: an important mechanism linking oxidative stress-inducing pathological factors to associated pathological conditions

Oxidative stress resulting from the accumulation of high levels of reactive oxygen species is a salient feature of, and a well-recognised pathological factor for, diverse pathologies. One common mechanism for oxidative stress damage is via the disruption of intracellular ion homeostasis to induce cell death. TRPM2 is a non-selective Ca2+-permeable cation channel with a wide distribution throughout the body and is highly sensitive to activation by oxidative stress. Recent studies have collected abundant evidence to show its important role in mediating cell death induced by miscellaneous oxidative stress-inducing pathological factors, both endogenous and exogenous, including ischemia/reperfusion and the neurotoxicants amyloid-β peptides and MPTP/MPP+ that cause neuronal demise in the brain, myocardial ischemia/reperfusion, proinflammatory mediators that disrupt endothelial function, diabetogenic agent streptozotocin and diabetes risk factor free fatty acids that induce loss of pancreatic β-cells, bile acids that damage pancreatic acinar cells, renal ischemia/reperfusion and albuminuria that are detrimental to kidney cells, acetaminophen that triggers hepatocyte death, and nanoparticles that injure pericytes. Studies have also shed light on the signalling mechanisms by which these pathological factors activate the TRPM2 channel to alter intracellular ion homeostasis leading to aberrant initiation of various cell death pathways. TRPM2-mediated cell death thus emerges as an important mechanism in the pathogenesis of conditions including ischemic stroke, neurodegenerative diseases, cardiovascular diseases, diabetes, pancreatitis, chronic kidney disease, liver damage and neurovascular injury. These findings raise the exciting perspective of targeting the TRPM2 channel as a novel therapeutic strategy to treat such oxidative stress-associated diseases

Food Legumes and Rising Temperatures: Effects, Adaptive Functional Mechanisms Specific to Reproductive Growth Stage and Strategies to Improve Heat Tolerance

Ambient temperatures are predicted to rise in the future owing to several reasons associated with global climate changes. These temperature increases can result in heat stress- a severe threat to crop production in most countries. Legumes are well-known for their impact on agricultural sustainability as well as their nutritional and health benefits. Heat stress imposes challenges for legume crops and has deleterious effects on the morphology, physiology, and reproductive growth of plants. High-temperature stress at the time of the reproductive stage is becoming a severe limitation for production of grain legumes as their cultivation expands to warmer environments and temperature variability increases due to climate change. The reproductive period is vital in the life cycle of all plants and is susceptible to high-temperature stress as various metabolic processes are adversely impacted during this phase, which reduces crop yield. Food legumes exposed to high-temperature stress during reproduction show flower abortion, pollen and ovule infertility, impaired fertilization, and reduced seed filling, leading to smaller seeds and poor yields. Through various breeding techniques, heat tolerance in major legumes can be enhanced to improve performance in the field. Omics approaches unravel different mechanisms underlying thermotolerance, which is imperative to understand the processes of molecular responses toward high-temperature stress
