Organizational system thinking as a cognitive framework to meet climate targets
System thinking is a crucial cognitive framework to enable individual pro-environmental behavioral changes. Indeed, a large body of literature has shown a significant and positive association between individuals' system thinking capacities and perceptions of the threat posed by climate change. However, individual behavioral changes play a limited role in addressing climate change compared to large organizations involved in a significantly larger share of economic activities. Do organizations exhibit system thinking capacities? Here, we conjecture that system thinking is a cognitive framework observable at an aggregated group level and, therefore, organizations, not just individuals, can exhibit characteristic levels of system thinking. We conceptualize a definition of organizational system thinking and develop an empirical method to estimate it using a large body of textual data from business organizations. Then, we show that system thinking organizations are more likely to lower emissions and align them with the pathways required to meet the climate targets set by the Paris Agreement. Finally, we discussed the theoretical and policy implication of our study. Overall, our results suggest that system thinking is a relevant organization-level cognitive framework that can help organizations align their emissions with global climate targets
Predominant polarity and polarity index of maintenance treatments for bipolar disorder: A validation study in a large naturalistic sample in Italy
Background and Objectives: Predominant polarity (PP) may be a useful course specifier in at least a significant proportion of patients with Bipolar Disorder (BD), being associated with several clinically relevant correlates. Emerging evidence suggests that the concept of PP might influence the selection of maintenance treatments, based on a drug polarity index (PI) which measures the greater antidepressive vs. antimanic preventive efficacy of mood stabilizers over long-term maintenance treatment. In this study, we aimed to validate the PI in a large sample of Italian BD patients with accurate longitudinal characterization of the clinical course, which ensured a robust definition of the PP. Materials and Methods: Our sample is comprised of 653 patients with BD, divided into groups based on the predominant polarity (manic/hypomanic predominant polarity—MPP, depressive predominant polarity—DPP and no predominant polarity). Subsequently we calculated the mean total polarity index for each group, and we compared the groups. Results: When we examined the mean PI of treatments prescribed to individuals with DPP, MPP and no predominant polarity, calculated using two different methods, we failed to find significant differences, with the exception of the PI calculated with the Popovic method and using the less stringent criterion for predominant polarity (PP50%). Conclusions: Future prospective studies are needed in order to determine whether the predominant polarity is indeed one clinical factor that might guide the clinician in choosing the right mood stabilizer for BD maintenance treatment
Prevalence and determinants of long-term utilization of antidepressant drugs: A retrospective cohort study
Purpose: Antidepressant consumption has risen in recent years, driven by longer treatment duration. The objective of this study was to measure the prevalence of antidepressant long-term and chronic use in the Bologna area, Italy, and to identify their main determinants. Materials and Methods: We conducted a retrospective claims-based cohort study by using the Bologna Local Health Authority data. A cohort of 18,307 incident users of antidepressant drugs in 2013 was selected, and subjects were followed for three years. A long-term utilization was defined as having at least one prescription claimed during each year of follow-up, while chronic utilization was defined as claiming at least 180 defined daily doses per year. Factors associated with chronic and long-term use were identified by univariate and multivariate logistic regressions. Results: In our cohort, 5448 (29.8%) and 1817 (9.9%) subjects were dispensed antidepressants for a long-term course and in a chronically way, respectively. Older age, antidepressant polytherapy, polypharmacy, and being prescribed the first antidepressant by a hospital physician were all factors independently associated with chronic and long-term prescriptions of antidepressant drugs. Results were reported separately for men and women. Conclusion: Antidepressant long-term and chronic prescriptions are common in the Bologna area. Because longer treatment should be clinically motivated, these results strongly prompt the need to evaluate the actual relevance, as they may indicate potentially inap-propriate prescription patterns
Fourth generation effects in rare exclusive B -> K^* l^+ l^- decay
Influence of the fourth generation, if ever exists, on the experimentally
measurable quantities such as invariant dilepton mass distribution, lepton
forward-backward asymmetry, and the ratio (Gamma_L/Gamma_T) of the decay widths
when K* meson is longitudinally and transversally polarized, is studied. Using
the experimental results on the branching ratios for the (B -> X_s) gamma and
semileptonic (B -> X_c l nu) decays, the two possible solutions of the 4x4
Cabibbo-Kobayashi-Maskawa factor (V_{t's} V_{t^'b}) are obtained as a function
of the t'-quark mass. It is observed that the results for the above-mentioned
physical quantities are essentially different from the standard model
predictions only for one solution of the CKM factor. In this case the
above-mentioned physical quantities can serve as efficient tools in search of
the fourth generation. The other solution yields almost identical results with
the SM.Comment: 19 pages, 10 postscripted figures, LaTeX formatte
Comparing the Prevalence of Polypharmacy and Potential Drug-Drug Interactions in Nursing Homes and in the Community Dwelling Elderly of Emilia Romagna Region
Backround: We aimed at assessing the prevalence of polypharmacy and potential drug-drug interactions (DDIs) with clinical relevance in elderly patient on Emilia Romagna area. Both outpatients and residents in nursing homes were assessed, with only partially overlapping strategies. Methods: We defined a list of 190 pairs of potentially interacting drugs, based on literature appraisal and availability of therapeutic alternatives. January-June 2018 data on drug use in patients over 65 years-old were collected from nine Local Health Authorities of Emilia Romagna: data on community-dwelling subjects were extracted from archives of reimbursed prescriptions, while drug use in a sample of nursing homes was recorded from clinical charts in one index day within the same semester. The frequency of polypharmacy (at least five or at least 10 concurrent drugs) and of each DDI was calculated. Results: In line with different rates of polypharmacy (80% vs 16%), the risk of exposure to at least one interaction was 53.7% in nursing homes and 26.4% in outpatients. Among DDIs, in nursing homes antidepressants—anxiolytics (11.9%) ranked first, followed by antidepressants—aspirin (7.4%). In outpatients, ACE-inhibitors—non-steroidal anti-inflammatory drugs (NSAIDs) reached 7.2% followed by the calcium channel blockers—α-blockers (2.4%). Discussion: Polypharmacy and risk of DDIs appeared very different in the two settings, due to both technical and clinical reasons. In order to reduce use of benzodiazepines, NSAIDs, antidepressants and relevant DDIs, 1) defining alternative options for pain relief in elderly outpatients, and 2) implementing non-pharmacological management of insomnia and anxiety in nursing homes should be prioritized
Personalizing Cancer Pain Therapy: Insights from the Rational Use of Analgesics (RUA) Group
Introduction: A previous Delphi survey from the Rational Use of Analgesics (RUA) project involving Italian palliative care specialists revealed some discrepancies between current guidelines and clinical practice with a lack of consensus on items regarding the use of strong opioids in treating cancer pain. Those results represented the basis for a new Delphi study addressing a better approach to pain treatment in patients with cancer. Methods: The study consisted of a two-round multidisciplinary Delphi study. Specialists rated their agreement with a set of 17 statements using a 5-point Likert scale (0 = totally disagree and 4 = totally agree). Consensus on a statement was achieved if the median consensus score (MCS) (expressed as value at which at least 50% of participants agreed) was at least 4 and the interquartile range (IQR) was 3–4. Results: This survey included input from 186 palliative care specialists representing all Italian territory. Consensus was reached on seven statements. More than 70% of participants agreed with the use of low dose of strong opioids in moderate pain treatment and valued transdermal route as an effective option when the oral route is not available. There was strong consensus on the importance of knowing opioid pharmacokinetics for therapy personalization and on identifying immediate-release opioids as key for tailoring therapy to patients’ needs. Limited agreement was reached on items regarding breakthrough pain and the management of opioid-induced bowel dysfunction. Conclusion: These findings may assist clinicians in applying clinical evidence to routine care settings and call for a reappraisal of current pain treatment recommendations with the final aim of optimizing the clinical use of strong opioids in patients with cancer
Porous polymer particles—A comprehensive guide to synthesis, characterization, functionalization and applications
The beam and detector of the NA62 experiment at CERN
NA62 is a fixed-target experiment at the CERN SPS dedicated to measurements of rare kaon decays. Such measurements, like the branching fraction of the K+ → π+ ν bar nu decay, have the potential to bring significant insights into new physics processes when comparison is made with precise theoretical predictions. For this purpose, innovative techniques have been developed, in particular, in the domain of low-mass tracking devices. Detector construction spanned several years from 2009 to 2014. The collaboration started detector commissioning in 2014 and will collect data until the end of 2018. The beam line and detector components are described together with their early performance obtained from 2014 and 2015 data
Using Secondary Structure Information for Protein Folding in CLP(FD)
The protein folding problem is the problem of predicting the 3D structure of a protein when the linear sequence of aminoacids identifying it is known. In this paper we present a declarative implementation in Constrain & Generate style in CLP(\u2131FD) of the protein folding problem, for models based on face-centered cubes. We use information concerning secondary structure (and other heuristics) to sensibly prune the search space. Preliminary results on real proteins are encouraging
Towards the Optimal Mineral N Fertilization for Improving Peeled Tomato Quality Grown in Southern Italy
Nitrogen (N) fertilization has often been used in excess by farmers to improve commercial yield and the profitability of processing tomato crops. However, N fertilizers greatly affect the overall tomato quality, including technological traits, nutritional characteristics, and mineral fruit composition. The aim of this work was to study the effects of increasing mineral N fertilization rates on processing tomato yield and quality when grown in Southern Italy conditions. The study was carried out at Battipaglia (Southern Italy) cropping cultivar “Messapico”, suitable for peeled tomato, and fruit quality was evaluated at the ripening stage. Results showed that N fertilization reduced sunburned fruits and resulted in increasing total yield, average fruit weight, as well as other fruit parameters (size, firmness, color indexes, pH, N, and calcium content). On the other hand, N fertilization negatively affected other fruit traits, such as dry matter and soluble solids content, total sugar index, ascorbic acid, and sodium content, while it had no effect on potassium and magnesium concentration in tomato fruits. Our results show that, in the investigated area, 200 kg N ha−1 is the best compromise to satisfy farmers and processors expectations, improve yield, and at the same time maintain good fruit quality attributes
