Exchange rate based disinflation, wage rigidity, and capital inflows : tradeoffs for Chile, 1977-81

Real exchange rate appreciation usually accompanies stabilization programs based on the exchange rate. One thing that causes the real exchange rate to appreciate is the capital inflows that follow liberalization of the capital account and the financial market. Capital inflows cause the exchange rate to appreciate in part because of the resulting increase in expenditures. This appreciation is exacerbated if there is some price rigidity, and if control of the money supply is only partial. All these conditions existed during Chile's experiment with exchange rate-based disinflation between 1978 and 1981. Simulating what might have been, the authors study how exchange rate based disinflation affects expenditures switching and reduction when wages are partially indexed in some segments of the labor market. The paper also shows the extent to which a more flexible rule on wage indexing would have offset the adverse impact of lower capital flows on protected sector employment.Economic Theory&Research,Macroeconomic Management,Environmental Economics&Policies,Economic Stabilization,Banks&Banking Reform

Setting the Table for Mediation Success: Supporting Disputants to Arrive Prepared

Consider the following two scenarios. Tom Jones sued his neighbor over a dispute they had regarding the boundaries of their abutting properties. Within a week of filing the suit, he received notice that a mediation had been scheduled for their case. Three weeks later he arrived at the appointed place and time of the mediation where he found his neighbor, his neighbor\u27s attorney, and a mediator. After brief introductions, they were invited to take their seats and were provided a short overview of mediation, a process that was new and unfamiliar to Tom Jones. Two hours later, he left in frustration. In another case, a probate judge ordered two sisters, Rose and Anne, to mediate their dispute over an inheritance. During mediation, their conversations often became heated and the mediator struggled to assist them in productively addressing their differences. After provocation by Anne, Rose started to cry and left the room, the mediation ended without an agreement. These two scenarios share a common denominator, they demonstrate a lack of preparation. Tom lacked familiarity with the mediation process, while Rose and Anne had not been forewarned of the potentially jarring interactions sometimes endemic to mediation. These situations are commonplace. This article addresses parties\u27 mediation preparedness, or more precisely unpreparedness

The Global Luxuries Tax

This chapter proposes a policy to tackle the problem of global poverty, the Global Luxuries Tax (GLT). The GLT is a levy collected whenever a person, anywhere in the world, purchases a certain luxury good or service. The money collected will go towards a Global Poverty Fund to be used to alleviate the worst cases of global poverty. The tax is a miniscule percentage of the price of the good or service being purchased, so that the GLT raises money for the Global Poverty Fund by virtue of the high number of transactions taking place. The first part of the chapter will highlight two main pitfalls faced by any potential solution to the problem of global poverty, the Unintended Consequences Objection and the Implementation Objection. The second and third parts will introduce the idea of a Global Luxuries Tax, first in theory and then in practice. Examples of luxuries to be taxed by the GLT include air travel, financial transactions, texting on mobile phones, and procreation. In the final part some objections to the GLT will be considered, and appeased

Endothelin-B Receptor Activation in Astrocytes Regulates the Rate of Oligodendrocyte Regeneration during Remyelination.

Reactive astrogliosis is an essential and ubiquitous response to CNS injury, but in some cases, aberrant activation of astrocytes and their release of inhibitory signaling molecules can impair endogenous neural repair processes. Our lab previously identified a secreted intercellular signaling molecule, called endothelin-1 (ET-1), which is expressed at high levels by reactive astrocytes in multiple sclerosis (MS) lesions and limits repair by delaying oligodendrocyte progenitor cell (OPC) maturation. However, as ET receptors are widely expressed on neural cells, the cell- and receptor-specific mechanisms of OPC inhibition by ET-1 action remain undefined. Using pharmacological approaches and cell-specific endothelin receptor (EDNR) ablation, we show that ET-1 acts selectively through EDNRB on astrocytes-and not OPCs-to indirectly inhibit remyelination. These results demonstrate that targeting specific pathways in reactive astrocytes represents a promising therapeutic target in diseases with extensive reactive astrogliosis, including MS

Effects of psychological interventions on anxiety and pain in patients undergoing major elective abdominal surgery: a systematic review

A maladaptive response to surgical stress might lead to postoperative complications. A multidisciplinary approach aimed at controlling the surgical stress response may reduce procedural complications and improve patients' quality of life in the short and long term. Several studies suggest that psychological interventions may interact with the pathophysiology of surgical stress response, potentially influencing wound repair, innate and adaptive immunity, inflammation, perception of pain, and patients' mood. The aim of this systematic review is to summarise the effects of perioperative psychological interventions on surgical pain and/or anxiety in adult patients scheduled for elective general abdominal and/or urologic surgery. We conducted a systematic review of controlled clinical trials and observational studies involving psychological interventions for adult patients scheduled for elective general abdominal and/or urologic surgery. Only studies reporting pain and/or anxiety among outcome measures were included in the systematic review. The following psychological interventions were considered: (1) relaxation techniques, (2) cognitive-behavioural therapies, (3) mindfulness, (4) narrative medicine, (5) hypnosis and (6) coping strategies. We examined 2174 papers. Among these, 9 studies were considered eligible for inclusion in this systematic review (1126 patients cumulatively): 8 are randomised controlled trials and 1 is an observational prospective pre/post study. Psychological characteristics widely influence the pathophysiological mechanisms underlying the neuroendocrine and inflammatory response to surgical stress, potentially interfering with surgical outcomes. Psychological interventions are technically feasible and realistically applicable perioperatively during abdominal and/or urologic surgery; they influence the pathophysiological mechanisms underlying maladaptive surgical stress response and might have positive effects on patients' surgical outcomes, such as pain and anxiety

Reversible Cardiomyopathies

Cardiomyopathy includes a diverse and heterogeneous group of disorders affecting the myocardium and eventually leading to cardiac dysfunction. Cardiomyopathy is the leading cause of hospitalization in patients older than 65 years of age and it is an important cause for enormous healthcare expenditure. All reversible cardiomyopathies can be associated with cardiomegaly, systolic heart failure, structural changes, and an increase in mortality, but when the offensive agent is identified and stopped, these conditions tend to stop their progression and reverse. The prognosis of reversible nonischemic cardiomyopathies is better than ischemic or other nonreversible cardiomyopathies. Additionally, it is important to diagnose etiology of HF early and precisely to determine prognosis and effective treatment. Most patients with reversible cardiomyopathy present with clinical picture similar to that of systolic heart failure. Here in this book chapter, we discuss about different types of reversible cardiomyopathy including pathogenesis, clinical picture, diagnosis and treatment

Autoimmunity plays a role in the onset of diabetes after 40 years of age

Funder: Umea UniversityAbstract: Aims/hypothesis: Type 1 and type 2 diabetes differ with respect to pathophysiological factors such as beta cell function, insulin resistance and phenotypic appearance, but there may be overlap between the two forms of diabetes. However, there are relatively few prospective studies that have characterised the relationship between autoimmunity and incident diabetes. We investigated associations of antibodies against the 65 kDa isoform of GAD (GAD65) with type 1 diabetes and type 2 diabetes genetic risk scores and incident diabetes in adults in European Prospective Investigation into Cancer and Nutrition (EPIC)-InterAct, a case-cohort study nested in the EPIC cohort. Methods: GAD65 antibodies were analysed in EPIC participants (over 40 years of age and free of known diabetes at baseline) by radioligand binding assay in a random subcohort (n = 15,802) and in incident diabetes cases (n = 11,981). Type 1 diabetes and type 2 diabetes genetic risk scores were calculated. Associations between GAD65 antibodies and incident diabetes were estimated using Prentice-weighted Cox regression. Results: GAD65 antibody positivity at baseline was associated with development of diabetes during a median follow-up time of 10.9 years (HR for GAD65 antibody positive vs negative 1.78; 95% CI 1.43, 2.20) after adjustment for sex, centre, physical activity, smoking status and education. The genetic risk score for type 1 diabetes but not type 2 diabetes was associated with GAD65 antibody positivity in both the subcohort (OR per SD genetic risk 1.24; 95% CI 1.03, 1.50) and incident cases (OR 1.97; 95% CI 1.72, 2.26) after adjusting for age and sex. The risk of incident diabetes in those in the top tertile of the type 1 diabetes genetic risk score who were also GAD65 antibody positive was 3.23 (95% CI 2.10, 4.97) compared with all other individuals, suggesting that 1.8% of incident diabetes in adults was attributable to this combination of risk factors. Conclusions/interpretation: Our study indicates that incident diabetes in adults has an element of autoimmune aetiology. Thus, there might be a reason to re-evaluate the present subclassification of diabetes in adulthood

The Long-Baseline Neutrino Experiment: Exploring Fundamental Symmetries of the Universe

The preponderance of matter over antimatter in the early Universe, the dynamics of the supernova bursts that produced the heavy elements necessary for life and whether protons eventually decay --- these mysteries at the forefront of particle physics and astrophysics are key to understanding the early evolution of our Universe, its current state and its eventual fate. The Long-Baseline Neutrino Experiment (LBNE) represents an extensively developed plan for a world-class experiment dedicated to addressing these questions. LBNE is conceived around three central components: (1) a new, high-intensity neutrino source generated from a megawatt-class proton accelerator at Fermi National Accelerator Laboratory, (2) a near neutrino detector just downstream of the source, and (3) a massive liquid argon time-projection chamber deployed as a far detector deep underground at the Sanford Underground Research Facility. This facility, located at the site of the former Homestake Mine in Lead, South Dakota, is approximately 1,300 km from the neutrino source at Fermilab -- a distance (baseline) that delivers optimal sensitivity to neutrino charge-parity symmetry violation and mass ordering effects. This ambitious yet cost-effective design incorporates scalability and flexibility and can accommodate a variety of upgrades and contributions. With its exceptional combination of experimental configuration, technical capabilities, and potential for transformative discoveries, LBNE promises to be a vital facility for the field of particle physics worldwide, providing physicists from around the globe with opportunities to collaborate in a twenty to thirty year program of exciting science. In this document we provide a comprehensive overview of LBNE's scientific objectives, its place in the landscape of neutrino physics worldwide, the technologies it will incorporate and the capabilities it will possess.Comment: Major update of previous version. This is the reference document for LBNE science program and current status. Chapters 1, 3, and 9 provide a comprehensive overview of LBNE's scientific objectives, its place in the landscape of neutrino physics worldwide, the technologies it will incorporate and the capabilities it will possess. 288 pages, 116 figure

Risk prediction for estrogen receptor-specific breast cancers in two large prospective cohorts

Background: Few published breast cancer (BC) risk prediction models consider the heterogeneity of predictor variables between estrogen-receptor positive (ER+) and negative (ER-) tumors. Using data from two large cohorts, we examined whether modeling this heterogeneity could improve prediction. Methods: We built two models, for ER+ (ModelER+) and ER- tumors (ModelER-), respectively, in 281,330 women (51% postmenopausal at recruitment) from the European Prospective Investigation into Cancer and Nutrition cohort. Discrimination (C-statistic) and calibration (the agreement between predicted and observed tumor risks) were assessed both internally and externally in 82,319 postmenopausal women from the Women’s Health Initiative study. We performed decision curve analysis to compare ModelER+ and the Gail model (ModelGail) regarding their applicability in risk assessment for chemoprevention. Results: Parity, number of full-term pregnancies, age at first full-term pregnancy and body height were only associated with ER+ tumors. Menopausal status, age at menarche and at menopause, hormone replacement therapy, postmenopausal body mass index, and alcohol intake were homogeneously associated with ER+ and ER- tumors. Internal validation yielded a C-statistic of 0.64 for ModelER+ and 0.59 for ModelER-. External validation reduced the C-statistic of ModelER+ (0.59) and ModelGail (0.57). In external evaluation of calibration, ModelER+ outperformed the ModelGail: the former led to a 9% overestimation of the risk of ER+ tumors, while the latter yielded a 22% underestimation of the overall BC risk. Compared with the treat-all strategy, ModelER+ produced equal or higher net benefits irrespective of the benefit-to-harm ratio of chemoprevention, while ModelGail did not produce higher net benefits unless the benefit-to-harm ratio was below 50. The clinical applicability, i.e. the area defined by the net benefit curve and the treat-all and treat-none strategies, was 12.7 × 10− 6 for ModelER+ and 3.0 × 10− 6 for ModelGail. Conclusions: Modeling heterogeneous epidemiological risk factors might yield little improvement in BC risk prediction. Nevertheless, a model specifically predictive of ER+ tumor risk could be more applicable than an omnibus model in risk assessment for chemoprevention
