Ocean State Estimation

Abstract Simulations and seasonal forecasts of tropical Pacific SST and subsurface fields that are based on the global Consortium for Estimating the Circulation and Climate of the Ocean (ECCO) ocean-state estimation procedure are investigated. As compared to similar results from a traditional ENSO simulation and forecast procedure, the hindcast of the constrained ocean state is significantly closer to observed surface and subsurface conditions. The skill of the 12-month lead SST forecast in the equatorial Pacific is comparable in both approaches. The optimization appears to have better skill in the SST anomaly correlations, suggesting that the initial ocean conditions and forcing corrections calculated by the ocean-state estimation do have a positive impact on the predictive skill. However, the optimized forecast skill is currently limited by the low quality of the statistical atmosphere. Progress is expected from optimizing a coupled model over a longer time interval with the coupling statistics being part of the control vector.

Abstract Variations in tropical Atlantic SST are an important factor in seasonal forecasts in the region and beyond. An analysis is given of the capabilities of the latest generation of coupled GCM seasonal forecast systems to predict tropical Atlantic SST anomalies. Skill above that of persistence is demonstrated in both the northern tropical and equatorial Atlantic, but not farther south. The inability of the coupled models to correctly represent the mean seasonal cycle is a major problem in attempts to forecast equatorial SST anomalies in the boreal summer. Even when forced with observed SST, atmosphere models have significant failings in this area. The quality of ocean initial conditions for coupled model forecasts is also a cause for concern, and the adequacy of the near-equatorial ocean observing system is in doubt. A multimodel approach improves forecast skill only modestly, and large errors remain in the southern tropical Atlantic. There is still much scope for improving forecasts of tropical Atlantic SST.

AbstractThis paper contributes to the literature on the determinants of trust by investigating how the quality of local services influences individuals’ generalized trust and trust in local governments. Using data from Italian national statistical office (Istat) Aspects of Daily Life survey, after building a new measure for the quality of local services, we study its effect on individuals’ trust using linear regressions techniques. Our findings suggest that good local public services have a positive impact on individuals’ trust, the effect being stronger for trust in local institutions. Our results are robust to potential endogeneity issues, tested using a two-step GMM estimation procedure, and to potential omitted variables bias, according to the method proposed by Altonji et al. (2005).

The Impact

Zakat is one of the five pillars of Islam which has a function of faith, social and economic functions. Muslims who can pay zakat are required to give at least 2.5 per cent of their wealth. The problem of poverty prevalent in disadvantaged regions because of the difficulty of access to information and communication led to a gap that is so high in wealth and resources. The instrument of zakat provides a paradigm in the achievement of equitable wealth distribution and healthy circulation. Zakat potentially offers a better life and improves the quality of human being. There is a human quality improvement not only in economic terms but also in spiritual terms such as improving religiousity. This study aims to examine the role of zakat to alleviate humanitarian issues in disadvantaged regions such as Sijunjung, one of zakat beneficiaries and impoverished areas in Indonesia. The researcher attempted a Cibest method to capture the impact of zakat beneficiaries before and after becoming a member of Zakat Community Development (ZCD) Program in material and spiritual value. The overall analysis shows that zakat has a positive impact on disadvantaged regions development and enhance the quality of life of the community. There is an improvement in the average of mustahik household incomes after becoming a member of ZCD Program. Cibest model demonstrates that material, spiritual, and absolute poverty index decreased by 10, 5, and 6 per cent. Meanwhile, the welfare index is increased by 21 per cent. These findings have significant implications for developing the quality of life in disadvantaged regions in Sijunjung. Therefore, zakat is one of the instruments to change the status of disadvantaged areas to be equivalent to other areas.

Heart failure (HF) affects more than 5 million people and has an increasing incidence and cost burden. Patients note symptoms of dyspnea and fatigue that result in a decreased quality of life, which has not drastically improved over the past decades despite advances in therapies. The assessment of exercise capacity can provide information regarding patient diagnosis and prognosis, while doubling as a potential future therapy. clinically, there is acceptance that exercise is safe in hf and can have a positive impact on morbidity and quality of life, although evidence for improvement in mortality is still lacking. specific prescriptions for exercise training have not been developed because many variables and confounding factors have prevented research trials from demonstrating an ideal regimen. Physicians are becoming more aware of the indices and goals for hf patients in exercise testing and therapy to provide comprehensive cardiac care. it is further postulated that a combination of exercise training and pharmacologic therapy may eventually provide the most benefits to those suffering from hf.

The Stability

The article presents scientific research in the field of statistical controllability of the food production process using the example of bakery products for a certain time interval using statistical methods of quality management. During quality control of finished products, defects in bakery products were identified, while the initial data were recorded in the developed form of a checklist for registering defects. It has been established that the most common defect is packaging leakage. For the subsequent statistical assessment of the stability of the production process and further analysis of the causes of the identified defect, a Shewhart control chart (p-card by an alternative feature) was used, which allows you to control the quality of manufactured products by the number of defects detected. Analyzing the control chart, it was concluded that studied process is conditionally stable, and the emerging defects are random. At the last stage of the research, the Ishikawa causal diagram was used, developed using the 6M mnemonic technique, in order to identify the most significant causes that affect the occurrence of the considered defect in bakery products. A more detailed study will allow the enterprise to produce food products that meet the established requirements.

Abstract Choral singing is a novel approach to reduce dementia stigma and social isolation while offering participants a sense of purpose, joy and social connection. The pervasiveness of stigma surrounding dementia remains one of the biggest barriers to living life with dignity following a diagnosis (Alzheimer Society of Canada, 2018). This paper examines how a social inclusion model of dementia care involving an intergenerational choir for people living with dementia, their care partners and high school students can reduce stigma and foster social connections. Multiple methodologies are used to investigate the effects of choir participation on cognition, stress levels, social connections, stigma, and quality of life. Results demonstrate the positive impact of choir participation and indicate that this socially inclusive intervention offers an effective, non-pharmacological alternative for older adults living with dementia in the community. Discussion focuses on the importance of instituting meaningful and engaging dementia-friendly activities at the community level.

BackgroundQuality improvement (QI) involves the use of systematic tools and methods to improve the quality of care and outcomes for patients. However, awareness and application of QI among healthcare professionals is poor and new strategies are needed to engage them in this area.ObjectivesThis study describes an innovative collaboration between one Higher Educational Institute (HEI) and Local Pharmaceutical Committees (LPCs) to develop a postgraduate QI module aimed to upskill community pharmacists in QI methods. The study explores pharmacist engagement with the learning and investigates the impact on their practice.MethodsDetails of the HEI–LPCs collaboration and communication with pharmacist were recorded. Focus groups were held with community pharmacists who enrolled onto the module to explore their motivation for undertaking the learning, how their knowledge of QI had changed and how they applied this learning in practice. A constructivist qualitative methodology was used to analyse the data.ResultsThe study found that a HEI–LPC partnership was feasible in developing and delivering the QI module. Fifteen pharmacists enrolled and following its completion, eight took part in one of two focus groups. Pharmacists reported a desire to extend and acquire new skills. The HEI–LPC partnership signalled a vote of confidence that gave pharmacists reassurance to sign up for the training. Some found returning to academia challenging and reported a lack of time and organisational support. Despite this, pharmacists demonstrated an enhanced understanding of QI, were more analytical in their day-to-day problem-solving and viewed the learning as having a positive impact on their team’s organisational culture with potential to improve service quality for patients.ConclusionsWith the increased adoption of new pharmacist’s roles and recent changes to governance associated with the COVID-19 pandemic, a HEI–LPC collaborative approach could upskill pharmacists and help them acquire skills to accommodate new working practices.

The demand for performing intravitreal injections has increased in recent years, prompting the need for more nurse training in their administration. The Great Western Hospitals NHS Trust in Swindon has developed a structured nurse training programme and now has 8 independent nurse injectors trained to undertake injections independently; nurse practitioners now contribute upwards of 85% of the total number of injections. The authors have also demonstrated the financial benefits of using injection assistant devices and shown the positive impact such devices have on training. In September 2019, the authors organised the first course to offer nurses and doctors hands-on experience in administering injections, using the Swindon training model to provide participants with a structured approach to learn how to perform intravitreal injections safely. Nurses made up 96% of participants; the remainder were doctors and managers; 6% had never performed an intravitreal injection; of units where they had, disposable drapes and a speculum were used in 71% of these. The number of injections performed per session at participants' units at the time they attended the course was: 17 or more injections=46%, 13–14=39%, and 11–12=15%. The course was rated 8.9/10 overall for content, with 85% very likely to recommend it to colleagues. All participants indicated that using the Swindon model made them feel confident to deliver injections safely. The authors demonstrated that using a structured training protocol and intravitreal assistant device improves the quality of nurse training and increases confidence in administering intravitreal injections.

The Impact

Background: One of the great challenges facing today’s society is the need to combat overweight and obesity in schoolchildren. This study aimed to analyze the impact of a cycle of didactic talks—given to families by a specialist in pediatrics, a specialist in nutrition and dietetics and a specialist in physical exercise—on childrens’ snack choices and nutrition quality. Methods: A longitudinal, quasi-experimental and quantitative investigation was designed, working with a total sample of 50 students divided into control and experimental groups. The nutritional quality of daily snacks was recorded during the month before and the month after the cycle of talks given by health experts. Results: An increase in the nutritional quality of the snacks was observed in the days after the talk—but, after a week, values returned to normal. Conclusions: The giving of educational talks to promote healthy habits may have a positive impact on the nutritional quality of school snacks in the days immediately following the talks. However, some forgetfulness was detected over time, which reduced the nutritional quality of the snacks once more. For future work, it is recommended that researchers measure the impact produced by giving regular talks.
