Aligning Aims in Innovation Management: a Participatory Approach to Defining Mission and Vision Statements

The problem of ensuring management and employees have clearly defined goals to work towards is one which has engaged management practitioners for some time. It is a challenge which engages organisations across industry sectors and business types (Prahalad 1999; O’Gorman 1999). This article describes the development of a framework for the identification of guiding goals for organisations using the principles of participatory design. The framework described involves internal and external stakeholders in the development of mission and vision statements. A pilot study using the initial stages of this framework was implemented with academic staff of an undergraduate academic programme in a Dublin higher education college. The need to foster an innovative culture among the multiple stakeholder groups involved in any academic programme make it an appropriate setting to pilot this activity. In the study, the initial phases of the framework were implemented and draft mission and vision statements were generated. The process of generating these statements is described and generic recommendations made for the implementation of this process in other settings

The storage capacity of Potts models for semantic memory retrieval

We introduce and analyze a minimal network model of semantic memory in the human brain. The model is a global associative memory structured as a collection of N local modules, each coding a feature, which can take S possible values, with a global sparseness a (the average fraction of features describing a concept). We show that, under optimal conditions, the number c of modules connected on average to a module can range widely between very sparse connectivity (c/N -> 0) and full connectivity (c = N), maintaining a global network storage capacity (the maximum number p of stored and retrievable concepts) that scales like c*S^2/a, with logarithmic corrections consistent with the constraint that each synapse may store up to a fraction of a bit.Comment: Accepted for publication in J-STAT, July 200

Explainable Machine Learning for Real-Time Hypoglycemia and Hyperglycemia Prediction and Personalized Control Recommendations

BACKGROUND: The occurrences of acute complications arising from hypoglycemia and hyperglycemia peak as young adults with type 1 diabetes (T1D) take control of their own care. Continuous glucose monitoring (CGM) devices provide real-time glucose readings enabling users to manage their control proactively. Machine learning algorithms can use CGM data to make ahead-of-time risk predictions and provide insight into an individual’s longer term control. METHODS: We introduce explainable machine learning to make predictions of hypoglycemia (270 mg/dL) up to 60 minutes ahead of time. We train our models using CGM data from 153 people living with T1D in the CITY (CGM Intervention in Teens and Young Adults With Type 1 Diabetes)survey totaling more than 28 000 days of usage, which we summarize into (short-term, medium-term, and long-term) glucose control features along with demographic information. We use machine learning explanations (SHAP [SHapley Additive exPlanations]) to identify which features have been most important in predicting risk per user. RESULTS: Machine learning models (XGBoost) show excellent performance at predicting hypoglycemia (area under the receiver operating curve [AUROC]: 0.998, average precision: 0.953) and hyperglycemia (AUROC: 0.989, average precision: 0.931) in comparison with a baseline heuristic and logistic regression model. CONCLUSIONS: Maximizing model performance for glucose risk prediction and management is crucial to reduce the burden of alarm fatigue on CGM users. Machine learning enables more precise and timely predictions in comparison with baseline models. SHAP helps identify what about a CGM user’s glucose control has led to predictions of risk which can be used to reduce their long-term risk of complications

S06-1 Putting young people at the heart of physical activity research design: The Walking In ScHools (WISH) Study

BACKGROUND: Young people have the right to be informed and consulted about decisions affecting their lives. Youth Patient and Public Involvement (PPI) should be encouraged to ensure research is carried out ‘with' or ‘by' young people rather than ‘to', ‘about' or ‘for' them. PPI can ensure research is relevant, results are accessible and recruitment rates are improved. Young people have had limited involvement in the design, implementation and dissemination of public health research and there have been calls for a greater focus on youth PPI in research. METHODS: Following the WISH feasibility study that consulted young people pre and post-intervention, a Youth Advisory Group (YAG) was set up within the main trial. The WISH study is a clustered randomised controlled trial in which a peer-led, school-based, brisk walking intervention is compared to usual physical activity in adolescent females. The YAG was introduced to inform intervention delivery and provide researchers with an understanding of what would encourage/discourage participation. Schools were asked to invite pupils aged 12-14 years (participants) and 15-18 years (walk leaders). Participative methods were used to develop and review study documentation. The YAG completed a short questionnaire and recruitment rates were monitored. RESULTS: Fourteen pupils from 3 schools attended the 2019 YAG meeting. The YAG agreed the meeting was a good way of getting young people involved in research (93%) and attendees enjoyed the meeting (100%). As a result, changes were made to study documentation, incentives were purchased and recruitment materials developed. Participant recruitment was higher in schools who participated in the YAG (54%) compared to those who did not (47%). In 2021 the second YAG occurred and 1 teacher, 12 participants and 10 walk leaders from 2 schools provided feedback on the trials COVID-19 contingency plan. The girls felt their feedback was valued (100%) and it was important young people had the chance to contribute to research studies (100%). CONCLUSIONS: The views of young people have been central to the development of the WISH Study and although youth PPI is not without challenges, there are many benefits for researchers, the study and the young people involved

The role and influence of "Champions" in a community-based lifestyle risk modification programme

This article describes the training and implementation of the Waist Disposal Challenge in service clubs in Western Australia in 2009–2010. Ninety-three Champions from 52 clubs were trained to deliver educational presentations to 1100 peers and facilitate a BMI competition among 764 peers. Champions reported significant improvements in their knowledge and confidence to motivate their peers to make changes to their diet and physical activity with 82% of participants completing the BMI competition and on average 58% experiencing and sustaining a BMI reduction for 12 months. It is evident that the Champions had influenced the uptake and success of the intervention

Long-term anaesthesia of broiler chickens

Objective To provide stable anaesthesia of long duration in broiler chickens in order to perform a terminal caecal ligated loop procedure. Study design Prospective experimental study. Animals Seven clinically healthy broiler chickens (Gallus domesticus) aged 27–36 days, weighing 884–2000 g. Methods Anaesthesia was induced and maintained with isoflurane in oxygen. All birds underwent intermittent positive pressure ventilation for the duration. End-tidal carbon dioxide, peripheral haemoglobin oxygen saturation, heart rate and oesophageal temperature were monitored continuously. All birds received intraosseous fluids. Butorphanol (2 mg kg–1) was administered intramuscularly at 2 hourly intervals. Euthanasia by parenteral pentobarbitone was performed at the end of procedure. Results Stable anaesthesia was maintained in four chickens for durations ranging from 435 to 510 minutes. One bird died and one was euthanized after 130 and 330 minutes, respectively, owing to surgical complications and another died from anaesthetic complication after 285 minutes. Conclusions and clinical relevance Long-term, stable anaesthesia is possible in clinically healthy chickens, provided complications such as hypothermia and hypoventilation are addressed and vital signs are carefully monitored. There are no known previous reports describing monitored, controlled anaesthesia of this duration in chickens

The PRECISE (PREgnancy Care Integrating translational Science, Everywhere) Network’s first protocol: deep phenotyping in three sub-Saharan African countries

Background: The PRECISE (PREgnancy Care Integrating translational Science, Everywhere) Network is a new and broadly-based group of research scientists and health advocates based in the UK, Africa and North America. Methods: This paper describes the protocol that underpins the clinical research activity of the Network, so that the investigators, and broader global health community, can have access to ‘deep phenotyping’ (social determinants of health, demographic and clinical parameters, placental biology and agnostic discovery biology) of women as they advance through pregnancy to the end of the puerperium, whether those pregnancies have normal outcomes or are complicated by one/more of the placental disorders of pregnancy (pregnancy hypertension, fetal growth restriction and stillbirth). Our clinical sites are in The Gambia (Farafenni), Kenya (Kilifi County), and Mozambique (Maputo Province). In each country, 50 non-pregnant women of reproductive age will be recruited each month for 1 year, to provide a final national sample size of 600; these women will provide culturally-, ethnically-, seasonallyand spatially-relevant control data with which to compare women with normal and complicated pregnancies. Between the three countries we will recruit ≈10,000 unselected pregnant women over 2 years. An estimated 1500 women will experience one/more placental complications over the same epoch. Importantly, as we will have accurate gestational age dating using the TraCer device, we will be able to discriminate between fetal growth restriction and preterm birth. Recruitment and follow-up will be primarily facility-based and will include women booking for antenatal care, subsequent visits in the third trimester, at time-of-disease, when relevant, during/ immediately after birth and 6 weeks after birth. Conclusions: To accelerate progress towards the women’s and children’s health-relevant Sustainable Development Goals, we need to understand how a variety of social, chronic disease, biomarker and pregnancy-specific determinants health interact to result in either a resilient or a compromised pregnancy for either mother or fetus/ newborn, or both. This protocol has been designed to create such a depth of understanding. We are seeking funding to maintain the cohort to better understand the implications of pregnancy complications for both maternal and child health

Physically fit or physically literate? Children with special educational needs understanding of physical education

The role of physical literacy within physical education (PE) has become a widely debated topic in recent years. Its role in educating children about physicality through embodiment, skill acquisition and reading the environment is argued to be of great benefit to children. However, whether children understand the role of PE in the development of these competencies is not clear, and this is even truer for children who have special educational needs (SEN). Drawing on qualitative phenomenological data from 30 children in key stages 2 and three (7 to 14 years of age) who have SEN, this paper explores notions of physical fitness and physical literacy as understood by children in PE lessons. It aims to gain insight into the ways that children understand the purpose of PE, and places these perceptions within a physical literacy framework, using the National Curriculum for PE (NCPE) as a foundation. Findings demonstrate that children with SEN perceive PE as a means for improving physical fitness, whereas concepts surrounding physical literacy appear to be lost. The paper concludes by making recommendations for factoring physical literacy components more forcibly into the PE curriculum, and through initial teacher training and continued professional development

Prebiotic Driven Increases in IL-17A Do Not Prevent Campylobacter jejuni Colonization of Chickens

© Copyright © 2020 Flaujac Lafontaine, Richards, Connerton, O’Kane, Ghaffar, Cummings, Fish and Connerton. Worldwide Campylobacter jejuni is a leading cause of foodborne disease. Contamination of chicken meat with digesta from C. jejuni-positive birds during slaughter and processing is a key route of transmission to humans through the food chain. Colonization of chickens with C. jejuni elicits host innate immune responses that may be modulated by dietary additives to provide a reduction in the number of campylobacters colonizing the gastrointestinal tract and thereby reduce the likelihood of human exposure to an infectious dose. Here we report the effects of prebiotic galacto-oligosaccharide (GOS) on broiler chickens colonized with C. jejuni when challenged at either an early stage in development at 6 days of age or 20 days old when campylobacters are frequently detected in commercial flocks. GOS-fed birds had increased growth performance, but the levels of C. jejuni colonizing the cecal pouches were unchanged irrespective of the age of challenge. Dietary GOS modulated the immune response to C. jejuni by increasing cytokine IL-17A expression at colonization. Correspondingly, reduced diversity of the cecal microbiota was associated with Campylobacter colonization in GOS-fed birds. In birds challenged at 6 days-old the reduction in microbial diversity was accompanied by an increase in the relative abundance of Escherichia spp. Whilst immuno-modulation of the Th17 pro-inflammatory response did not prevent C. jejuni colonization of the intestinal tract of broiler chickens, the study highlights the potential for combinations of prebiotics, and specific competitors (synbiotics) to engage with the host innate immunity to reduce pathogen burdens
