This paper examines the positive aspects of aging. Some items, such as valuable and rare stamps, old coins, works of art, and antiques, become more expensive over time. More popular examples demonstrating the positive effect of aging that influences price are the aging of boutique wine and artisan cheese. The present paper examines the wine aging process that brings about quality improvement. This process also leads to determining (i) optimal aging periods for different wines; (ii) optimal grape juice inventory allocations and prices for different wines; (iii) optimal quantities of different kinds of wine; and (iv) the time durations of wine production and consumption from each vintage. These aspects are considered in an environment in which the demand increases over time due to the aging and rarity of the product.

We empirically test whether B Corp certification affects the short- and medium-term growth rates of sustainable enterprises. These businesses are growing in popularity and prevalence but, due to their hybrid nature, often suffer from external credibility issues and competing internal logics. Because of the rigorous and time-involving audit procedure, B Corp certification potentially sends a credible signal about the sustainable nature of the enterprise to its stakeholders. In addition, the B Corp label could help to straighten out internal tensions and align the company towards its dual purpose. Hence, B Corp certification could contribute to company success. We observe 129 firms that were certified between 2013 and 2018 over a period between six years prior and five years post-certification. Using propensity score matching, we identify 129 non-certified matching companies. On this sample, we conduct a difference-in-differences panel regression analysis to investigate the effect of certification. Our dataset allows us to study how the effects of B Corp certification evolve over time, which was previously untested. Our study documents a positive effect of B Corp certification on turnover growth and also that this effect increases with the time since certification, implying that certification requires some time for its full effect to become apparent.

Development of calves depends on prenatal and postnatal conditions. Primiparous cows were still maturing during pregnancy, which can lead to negative intrauterine conditions and affect the calf’s metabolism. It is hypothesized that weaning calves at higher maturity has positive effects due to reduced metabolic stress. We aimed to evaluate effects of mothers’ parity and calves’ weaning age on growth performance and blood metabolites. Fifty-nine female Holstein calves (38.8 ± 5.3 kg birth weight, about 8 days old) were used in a 2 × 2 factorial experiment with factors weaning age (7 vs. 17 weeks) and parity of mother (primiparous vs. multiparous cows). Calves were randomly assigned one of these four groups. Live weight, live weight gain and morphometry increased over time and were greater in calves weaned later. Metabolic indicators except total protein were interactively affected by time and weaning age. Leptin remained low in early-weaned calves born to primiparous cows, while it increased in the other groups. The results suggest that weaning more mature calves has a positive effect on body growth, and calves born to primiparous cows particularly benefit from this weaning regimen. It also enables a smooth transition from liquid to solid feed, which might reduce the associated stress of weaning.

What does ‘value’ mean? In the context of dental care, it can be defined as the quality of care received by a patient divided by the cost to the patient of receiving that care. In other words: V =Q/C, where Q equals the quality improvement over time, which most patients view in the context of the outcome, the service provided and safety/risk management, and C equals the financial, biological and time cost to the patient. Here, the need for, and implications of, value-based density for clinicians and patients alike are explored.

Title: Quality Improvement in the Outpatient Setting: Observations from the PINNACLE Registry® 2009 Q4-2013 Q1 Authors: Katie Kehoe BSN, MS 1 ; Sherry Shultz RN, BSN, CIO 2 ; Fran Fiocchi MPH 1 ; Qiong Li PhD 1 ; Thomas Shields 1 ; Charlie Devlin MD FACC, FACP, FASNC 2 ; Nathan T Glusenkamp, MA 1 ; J. Brendan Mullen 1 ; Angelo Ponirakis, PhD 1 ; 1 American College of Cardiology, Washington, DC 2 South Carolina Heart Center, Columbia SC Background: The PINNACLE Registry® at the American College of Cardiology is the first outpatient practice-based quality improvement program in the United States. Begun as a pilot program in 2007, the registry systematically collects and reports on adherence to clinical guidelines in the care of patients with coronary artery disease, hypertension, atrial fibrillation and heart failure. Over time, these reports offer a unique opportunity for Quality Improvement (QI) in the outpatient setting. The current study aimed to assess the effect of QI in the outpatient setting using PINNACLE Registry data. Methods: The South Carolina Heart Center is a cardiovascular practice in Columbia, South Carolina. There are 19 providers, 5 office locations and NextGen EMR. The practice’s Quality Committee and Board meet monthly to review PINNACLE reports and identify areas for QI. This Clinical Quality Improvement Initiative began 10 years ago and consists of physicians, nurses, administrators, medical assistants, a medical record analyst and information systems staff. During this review, providers’ data was not blinded to others. QI Interventions implemented included physician and staff education, improving documentation during the office visit, addition of necessary fields to capture missing data and routine planned internal audits. Between October 1, 2009 and March 31, 2013 a total of 161,873 patient encounters were submitted to the registry. A two-tailed z test was performed to assess the significance in percentage changes between 2009 to 2013. Results: The following table showed significant percentage changes in six performance measures indicating interventions implemented by the practice demonstrate significant quality improvement over time from 2009-2013. Conclusions: Utilizing their PINNACLE Registry reports, the South Carolina Heart Center identified several areas for QI. Implementing multiple interventions, this practice was able to significantly improve their PINNACLE Reports and the quality of care provided.

This study distinguishes different patterns of friendship quality in terms of support from and conflict with friends, and reciprocity. Associations between friendship patterns and adolescents' adjustment (self-perception, expectations for the future, depressive feelings, sense of alienation, lying, disobedience, and aggression) were hypothesized to be moderated by family stress and friendship reciprocity. The sample comprised 622 adolescents of both genders, aged 14 to 20 years. We administered a questionnaire, including the Friendship Quality Scale and a peer nomination, twice at a 6-month interval. We identified two patterns of stable friendships: high (47%) and low (37%) quality. In two other groups, friendship quality changed over time, either from low to high (7%), or from high to low (9%). Of all adolescents, 58% had reciprocal and stable friends and 42% had unilateral friends. Under conditions of high family stress, supportive friendships do not have a positive effect on expectations for success and sense of alienation. Reciprocal friendship promotes higher levels of lying and disobedience but also protects against aggression. Summarizing, the effects of friendship quality can be moderated, either diminishing or exacerbating it, by other context factors.

Abstract Background: Care bundles are a set of three to five evidence-informed practices which, when performed collectively and reliably, may improve health system performance and patient care. To date, many studies conducted to improve the quality of essential birth care practices (EBPs) have focused primarily on provider- level and have fallen short of the predicted impact on care quality, indicating that a systems approach is needed to improve the delivery of reliable quality care. This study evaluates the effectiveness of integrating the use of the World Health Organization Safe Childbirth Checklist (WHO-SCC) into a district-wide system improvement collaborative program designed to improve and sustain the delivery of EBPs as measured by "clinical bundle" adherence over-time.Methods: The WHO-SCC was introduced in the context of a district-wide Maternal and Newborn Health (MNH) collaborative quality of care improvement program in four agrarian Ethiopia regions. Three "clinical bundles" were created from the WHO-SCC: On Admission, Before Pushing, and Soon After Birth bundles. The outcome of each bundle was measured using all- or- none adherence. Adherence was assessed monthly by reviewing charts of live births.A time-series analysis was employed to assess the effectiveness of system-level interventions on clinical bundle adherence. STATA version 13.1 was used to analyze the trend of each bundle adherence overtime. Autocorrelation was checked to assess if the assumption of independence in observations collected overtime was valid. Prais-Winsten was used to minimize the effect of autocorrelation.Findings: Quality improvement interventions targeting the three clinical bundles resulted in improved adherence over time across the four regions. In Tigray region, adherence to “On Admission” bundle was increased monthly on average by B =1.39 (95% CI; 0.47 - 2.32; P<0.005).Similarly, adherence to the “Before Pushing” bundle in Southern Nations, Nationalities and People’s (SNNP) region increased monthly on average by B = 2.3 (95% CI; 0.89 - 3.74; P<0.005). Conclusion: Use of the WHO-SCC paired with a system-wide quality improvement approach improved and sustained quality of EBPs delivery. Further studies should be conducted to evaluate the impact on patient-level outcomes.

<p>The different evolution of wine production and consumption in Spain in recent decades has pushed the sector into a model which is highly dependent on international markets. In these circumstances, the variable that determines the viability of many enterprises is the performance of exports. This article evaluates the performance of Spanish wine exports using a set of indicators that measure their diversification, adaptation and competitiveness in target markets. The results show a positive export performance in three dimensions, which contributes to determine the keys to their success, especially in volume, and to guide future strategies.</p>
