    Sickle cell disease is characterized by chronic hemolytic anemia and vaso-occlusive painful crisis. The vascular occlusion in sickle cell disease is a complex process and accounts for the majority of the clinical manifestations of the disease. Abdominal pain is an important component of vaso-occlusive painful crisis and may mimic diseases such as acute appendicitis and cholecystitis. Acute pancreatitis is rarely included as a cause of abdominal pain in patients with sickle cell disease. When it occurs it may result form biliary obstruction, but in other instances it might be a consequence of microvessel occlusion causing ischemia. In this series we describe four cases of acute pancreatitis in patients with sickle cell disease apparently due to microvascular occlusion and ischemic injury to the pancreas. All patients responded to conservative management. Acute pancreatitis should be considered in the differential diagnosis of abdominal pain in patients with sickle cell disease.

    Full Text Available The predominant pathophysiological feature of homozygous sickle cell anemia (SCA is the vaso-occlusion. Vaso-occlusion can be associated with painful crises, which are the primary reason for those patients to seek medical care. Vaso-occlusion is responsible for the acute chest syndrome (ACS with large morbidity and mortality or more rarely (and especially in adults for priapism and acute neurological events (strokes. A 10-year-old boy with homozygous SCA was admitted to the Pediatric Emergencies with painful vaso-occlusive crisis and fever. Initially he had normal chest X-ray but, after 24-hour-hospitalization, he developed  ACS with new chest X-ray findings. He was treated with broad spectrum antibiotics, blood transfusions and bronchodilators and after a  six-day treatment, he was significantly improved. The patient was discharged 13 days later with no other therapy at home. The possibility of  ACS development should be still considered, even when a  known patient with SCA presents a  painful vaso-occlusive crisis with an initial normal chest X-ray. Therefore, repeated clinical examination is required and possible changes in  the clinical status could indicate the necessity of a  new radiographic examination. In  this way, early  ACS could be recognized and the catastrophic consequences due to this syndrome could be avoided.

    Full Text Available BACKGROUND: Frequent painful vaso-occlusive crises (VOCs were associated with mortality in the Cooperative Study of Sickle Cell Disease (CSSCD over twenty years ago. Modern therapies for sickle cell anemia (SCA like hydroxyurea are believed to have improved overall patient survival. The current study sought to determine the relevance of the association between more frequent VOCs and death and its relative impact upon overall mortality compared to other known risk factors in a contemporary adult SCA cohort. METHODS: Two hundred sixty four SCA adults were assigned into two groups based on patient reported outcomes for emergency department (ED visits or hospitalizations for painful VOC treatment during the 12 months prior to evaluation. RESULTS: Higher baseline hematocrit (p = 0.0008, ferritin (p = 0.005, and HDL cholesterol (p = 0.01 were independently associated with 1 or more painful VOCs requiring an ED visit or hospitalization for acute pain. During a median follow-up of 5 years, mortality was higher in the ED visit/hospitalization group (relative risk [RR] 2.68, 95% CI 1.1-6.5, p = 0.03. Higher tricuspid regurgitatant jet velocity (TRV (RR 2.41, 95% CI 1.5-3.9, p < 0.0001, elevated ferritin (RR 4.00, 95% CI 1.8-9.0, p = 0.001 and lower glomerular filtration rate (RR=2.73, 95% CI 1.6-4.6, p < 0.0001 were also independent risk factors for mortality. CONCLUSIONS: Severe painful VOCs remain a marker for SCA disease severity and premature mortality in a modern cohort along with other known risk factors for death including high TRV, high ferritin and lower renal function. The number of patient reported pain crises requiring healthcare utilization is an easily obtained outcome that could help to identify high risk patients for disease modifying therapies.

    Acute vaso-occlusive crisis (VOC) is a hallmark of sickle cell disease (SCD). Multiple complex pathophysiological processes can result in pain during a VOC. Despite significant improvements in the understanding and management of SCD, little progress has been made in the management of pain in SCD, although new treatments are being explored. Opioids and non-steroidal anti-inflammatory drugs (NSAIDs) remain the mainstay of treatment of VOC pain, but new classes of drugs are being tested to prevent and treat acute pain. Advancements in the understanding of the pathophysiology of SCD and pain and the pharmacogenomics of opioids have yet to be effectively utilized in the management of VOC. Opioid tolerance and opioid-induced hyperalgesia are significant problems associated with the long-term use of opioids, and better strategies for chronic pain therapy are needed. This report reviews the mechanisms of pain associated with acute VOC, describes the current management of VOC, and describes some of the new therapies under evaluation for the management of acute VOC in SCD.

    Vascular resistance and tissue perfusion may be both affected by impaired vascular function and increased blood viscosity. Little is known about the effects of vascular function on the occurrence of painful vaso-occlusive crises (VOC) in children with sickle cell anemia (SCA). The aim of the present study was to determine which side of the balance (blood viscosity or vascular function) is the most deleterious in SCA and increases the risk for frequent hospitalized VOC. Microvascular function, microcirculatory oxygenation and blood viscosity were determined in a group of 22 SCA children/adolescents at steady state and a group of 13 healthy children/adolescents. Univariate analyses demonstrated blunted microvascular reactivity during local thermal heating test and decreased microcirculatory oxygenation in SCA children compared to controls. Multivariate analysis revealed that increased blood viscosity and decreased microcirculatory oxygenation were independent risk factors of frequent VOC in SCA. In contrast, the level of microvascular dysfunction does not predict VOC rate. In conclusion, increased blood viscosity is usually well supported in healthy individuals where vascular function is not impaired. However, in the context of SCA, microvascular function is impaired and any increase of blood viscosity or decrease in microcirculatory oxygenation would increase the risks for frequent VOC.

    Neuropathic pain is a known component of vaso-occlusive pain in sickle cell disease; however, drugs targeting neuropathic pain have not been studied in this population. Trials of acute pain are complicated by the need to obtain consent, to randomize participants expeditiously while optimally treating pain. We describe the challenges in designing and implementing the Pain Management of Vaso-occlusive Crisis in Children and Young Adults with Sickle Cell Disease Study (NCT01954927), a phase II, randomized, double-blind, placebo-controlled trial to determine the effect of gabapentin for vaso-occlusive crisis. In the Pain Management of Vaso-occlusive Crisis in Children and Young Adults with Sickle Cell Disease Study, we aim to assess the analgesic effect of gabapentin during vaso-occlusive crisis. Difficulties we identified included avoiding delay of notification of study staff of potential participants which we resolved by automated notification. Concern for rapid randomization and drug dispensation was addressed through careful planning with an investigational pharmacy and a single liquid formulation. We considered obtaining consent during well-visits to avoid the time constraints with acute presentations, but the large number of patients and limited duration that consent is valid made this impractical. In all, 79% of caregivers/children approached have agreed to participate. The trial is currently active, and enrollment is at 45.8% of that targeted (76 of 166) and expected to continue for two more years. Maintaining staff availability after-hours remains problematic, with 8% of screened patients missed for lack of available staff. Lessons learned in designing a trial to expedite procedures in the acute pain setting include (1) building study evaluations upon a standard-of-care backbone; (2) implementing a simple study design to facilitate consent and data capture; (3) assuring ample, well-trained study staff; and (4) utilizing technology to automate procedures

    Describe the treatment of patients with vaso-occlusive crises (VOC) in a Brazilian emergency department (ED) and the successful switch from intravenous to oral morphine. We analyzed records of 315 patients with sickle cell disease using two different protocols for pain: one in March 2010 prescribing intravenous morphine every 4 h throughout their stay, and another in March 2011 and 2012 prescribing one initial dose of intravenous morphine followed by equianalgesic doses of oral morphine every 4 h. Patients were triaged into three groups: mild, moderate, and severe VOC. The mild group was treated within 1 h after triage, the moderate within 30 min and the severe was treated immediately. Patients whose pain was not relieved within 6 h after the first dose of morphine were transferred into a different holding area of the ED where they continued to receive the same treatment for 48 h after which they were hospitalized if still in pain. The number of patients who stayed <24 h in the ED increased significantly from 63 in 2010 to 87 in 2012, and the number of admissions decreased from 26 in 2010 to 10 in 2012. The incidence of acute chest syndrome decreased from 8.5% in 2010 to 1.9% in 2012. Patients treated with oral morphine stayed a shorter time in the ED, had more pain relief, were admitted less frequently, and had less acute chest syndrome. These differences may be due to environmental, cultural, psychological, and pharmacogenetic factors. © 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Pediatric sickle cell disease, highly prevalent in sub-Saharan Africa, carries great morbidity and mortality risk. Limited resources and monitoring make management of acute vaso-occlusive crises challenging. This study aims to evaluate the efficacy and safety of subdissociative intranasal ketamine as a cheap, readily available and easily administered adjunct to standard pain therapy. We hypothesise that subdissociative, intranasal ketamine may significantly augment current approaches to pain management in resource-limited settings in a safe and cost-effective manner. This is a multicentred, randomised, double-blind, placebo-controlled trial enrolling children 4-16 years of age with sickle cell disease and painful vaso-occlusive pain crises. Study sites include two sub-Saharan teaching and referral hospitals with acute intake areas. All patients receive standard analgesic therapy during evaluation. Patients randomised to the treatment arm receive 1 mg/kg intranasal ketamine at onset of therapy, while placebo arm participants receive volume-matched intranasal normal saline. All participants and clinical staff are blinded to the treatment allocation. Data will be analysed on an intention-to-treat basis. Primary endpoints are changes in self-report pain scales (Faces Pain Scale-Revised) at 30, 60 and 120 minutes and rates of adverse events. Secondary endpoints include hospital length of stay, total analgesia use and quality of life assessment 2-3 weeks postintervention. The research methods for this study have been approved by the Cameroon Baptist Convention Health Board Institutional Review Board (IRB2015-07), the Tanzanian National Institute for Medical Research (NIMR/HQ/R.8a/Vol. IX/2299), Muhimbili National Hospital IRB (MNH/IRB/I/2015/14) and the Tanzanian Food and Drugs Authority (TFDA0015/CTR/0015/9). Data reports will be provided to the Data and Safety Monitoring Board (DSMB) periodically throughout the study as well as all reports of adverse events. All

This study investigated the association of the SOD2 polymorphism and superoxide dismutase (SOD activity with vaso-occlusive crisis (VOC and acute splenic sequestration (ASS in children with sickle cell anemia (SCA. One hundred ninety-five children aged 1-9 years old were analyzed. The TC and CC genotypes were associated with lower SOD activity compared with the TT genotype (p=0.0321; p=0.0253, respectively. Furthermore, TC/CC were more frequent in patients with VOC or ASS (p=0.0285; p=0.0090, respectively. These results suggest that the SOD2 polymorphism associated with low SOD activity could be involved in SCA physiopathology.

    The most common, debilitating morbidity of sickle cell disease (SCD) is vaso-occlusive crisis (VOC) pain. Although guidelines exist for its management, they are generally not well-followed, and research in other pediatric diseases has shown that clinical pathways improve care. The purpose of our study was to determine whether a clinical pathway improves the acute management of sickle cell vaso-occlusive crisis (VOC) pain in the pediatric emergency department (PED). Pain management practices were prospectively investigated before and after the initiation of a clinical pathway in the PED of an urban, tertiary care center with 50,000 ED visits per year and approximately 200 active sickle cell patients. The pathway included instructions for triage, monitoring, medication administration, and timing of assessments and interventions. Data were eligible from 35 pre-pathway and 33 post-pathway visits. Primary outcome was time interval to administration of first analgesic medication. Statistical analysis was by Student's t-test, using natural-log-transformed data for outcomes with skewed distribution curves. Time interval to first analgesic improved from 74 to 42 minutes (P = 0.012) and to first opioid from 94 to 46 minutes (P = 0.013). The percentage of patients who received ketorolac increased from 57% to 82% (P = 0.03). Decrease in time interval to subsequent pain score assessment was not statistically significant (110 to 72 minutes (P = 0.07)), and change in pain score was not different (P = 0.25). The use of a clinical pathway for sickle cell VOC in the PED can improve important aspects of pain management and merits further investigation and implementation. © 2013 Wiley Periodicals, Inc.

    SCD stems from amutation in the beta globin gene. Upon deoxygenation, hemoglobin polymerizes and triggers RBC remodeling. This phenomenon is central to SCD pathogenesis as individuals suffering from the disease are plagued by painful vaso-occlusive crises episodes. These episodes are the result of a combination of processes including inflammation, thrombosis, and blood cell adhesion to the vascular wall which leads to blockages within the vasculature termed vaso-occlusions. Vaso-occlusive episodes deprive tissues of oxygen and are a major contributor to SCD-related complications; unfortunately, the complex mechanisms that contribute to vaso-occlusions are not well understood. Vaso-occlusions can occur in post-capillary venules; hence, the microvasculature is a prime target for SCD therapies. Traditional in vitro systems poorly recapitulate architectural and dynamic flow properties of in vivo systems. However, microfluidic devices can capture features of the native vasculature such as cellular composition, flow, geometry, and ECM presentation. This review, although not comprehensive, highlights microfluidic approaches that aim to improve our current understanding of the pathophysiological mechanisms surrounding SCD. Microfluidic platforms can aid in identifying factors that may contribute to disease severity and can serve as suitable test beds for novel treatment strategies which may improve patient outcomes. © 2017 John Wiley & Sons Ltd.

    Vaso-occlusion crisis is one of the key hallmark of sickle cell anemia. While early studies suggested that the crisis is caused by blockage of a single elongated cell, recent experimental investigations indicate that vaso-occlusion is a complex process triggered by adhesive interactions among different cell groups in multiple stages. Based on dissipative particle dynamics, a multi-scale model for the sickle red blood cells (SS-RBCs), accounting for diversity in both shapes and cell rigidities, is developed to investigate the mechanism of vaso-occlusion crisis. Using this model, the adhesive dynamics of single SS-RBC was investigated in arterioles. Simulation results indicate that the different cell groups (deformable SS2 RBCs, rigid SS4 RBCs, leukocytes, etc.) exhibit heterogeneous adhesive behavior due to the different cell morphologies and membrane rigidities. We further simulate the tube flow of SS-RBC suspensions with different cell fractions. The more adhesive SS2 cells interact with the vascular endothelium and further trap rigid SS4 cells, resulting in vaso-occlusion in vessels less than 15 μm . Under inflammation, adherent leukocytes may also trap SS4 cells, resulting in vaso-occlusion in even larger vessels.

    Treatment of vaso-occlusive crises (VOC) or events in sickle cell disease (SCD) remains limited to symptom relief with opioids. Animal models support the effectiveness of the pan-selectin inhibitor GMI-1070 in reducing selectin-mediated cell adhesion and abrogating VOC. We studied GMI-1070 in a prospective multicenter, randomized, placebo-controlled, double-blind, phase 2 study of 76 SCD patients with VOC. Study drug (GMI-1070 or placebo) was given every 12 hours for up to 15 doses. Other treatment was per institutional standard of care. All subjects reached the composite primary end point of resolution of VOC. Although time to reach the composite primary end point was not statistically different between the groups, clinically meaningful reductions in mean and median times to VOC resolution of 41 and 63 hours (28% and 48%, P = .19 for both) were observed in the active treatment group vs the placebo group. As a secondary end point, GMI-1070 appeared safe in acute vaso-occlusion, and adverse events were not different in the two arms. Also in secondary analyses, mean cumulative IV opioid analgesic use was reduced by 83% with GMI-1070 vs placebo (P = .010). These results support a phase 3 study of GMI-1070 (now rivipansel) for SCD VOC. This trial was registered at www.clinicaltrials.gov as #NCT01119833. PMID:25733584

    Sickle cell disease is clinically characterized with vaso-occlusive painful crisis which is pleomorphic in terms of frequency of occurrence. The intracellular polymerization of deoxygenated hemoglobin S increases the internal viscosity of the sickle cells exponentially, concurrent with binding of hemoglobin S to the membrane and discocyte-drepanocyte transformation. As a result, the red cells in sickle cell disease are heterogenous with cells of varying density and mean corpuscular hemoglobin concentration which alter the rheological features of the blood in the microcirculation. The cellular, physiological, biochemical and rheological factors that contribute to the vaso-occlusive events are not completely understood. Nonetheless, recent clinical studies have demonstrated that a certain fraction of the dense cells disappear during sickle cell painful crisis. In an attempt to elucidate some of the cellular and rheological factors involved in the initiation of vaso-occlusion, the authors have employed intravital videomicroscopy and radionuclide imaging of indium-III labeled sickle cells to determine the dynamics and sites of vaso-occlusion using the rat exchanged-transfused with sickle (HbSS) erythrocytes as a model

    Painful vaso-occlusive crisis, a hallmark of sickle cell anaemia, results from complex, incompletely understood mechanisms. Red blood cell (RBC) damage caused by continuous endogenous and exogenous oxidative stress may precipitate the occurrence of vaso-occlusive crises. In order to gain insight into the relevance of oxidative stress in vaso-occlusive crisis occurrence, we prospectively compared the expression levels of various oxidative markers in 32 adults with sickle cell anaemia during vaso-occlusive crisis and steady-state conditions. Compared to steady-state condition, plasma levels of free haem, advanced oxidation protein products and myeloperoxidase, RBC caspase-3 activity, as well as the concentrations of total, neutrophil- and RBC-derived microparticles were increased during vaso-occlusive crises, whereas the reduced glutathione content was decreased in RBCs. In addition, natural anti-band 3 autoantibodies levels decreased during crisis and were negatively correlated with the rise in plasma advanced oxidation protein products and RBC caspase-3 activity. These data showed an exacerbation of the oxidative stress during vaso-occlusive crises in sickle cell anaemia patients and strongly suggest that the higher concentration of harmful circulating RBC-derived microparticles and the reduced anti-band 3 autoantibodies levels may be both related to the recruitment of oxidized band 3 into membrane aggregates. © 2016 John Wiley & Sons Ltd.

    Patients with sickle cell disease (SCD) suffer from intermittent vaso-occlusive pain crises (VOCs). These crises lead to frequent hospitalizations, significant morbidity, and increased mortality risk. Care pathways can enhance efficiency and quality of care. Our study sought to evaluate the development and implementation of a care pathway for patients with SCD experiencing VOCs. The University of North Carolina (UNC) Comprehensive Sickle Cell Program provides all levels of care for a large population of patients with sickle cell anemia. All patients admitted to UNC Hospitals with SCD VOCs from January 2009 through June 2011 were evaluated. During this time period, we also assessed sequential prospective cohorts during progressive phases of developing and implementing a quality improvement and pathway of care program for this patient population in our study. The developed pathway entailed geographic localization for VOC patients, a single group of faculty physicians caring for these patients, and early use of patient-controlled analgesia (PCA) to achieve pain control. Physicians from the UNC Hospital Medicine Program were responsible for the initiatives. Cohorts were compared to a baseline historical control. Outcomes of interest included patient length of stay (LOS) in the hospital, 30-day readmission rate, need for transfusion, incidence of acute chest syndrome, use of naloxone, and use of PCA. Compared with an historical baseline cohort, the development and implementation of a VOC care pathway for patients with SCD led to reduction in average hospital LOS by 1.44 days (P management of patients with SCD VOCs using a care pathway that emphasizes early, aggressive PCA-based pain control is associated with reduced hospital LOS. The LOS reduction seen in our study is clinically meaningful. Notably, other measures of patient outcomes and quality of care metrics did not change significantly, and some trended towards improvement.

    Sickle cell disease (SCD) vaso-occlusive crisis (VOC) remains an important cause of acute pain in pediatrics and the most common SCD complication. Pain management recommendations in SCD include nonpharmacological interventions. Yoga is one nonpharmacological intervention that has been shown to reduce pain in some populations; however, evidence is lacking in children with VOC. The primary objective of this study was to compare the effect of yoga vs. an attention control on pain in children with VOC. The secondary objectives were to compare the effect of yoga vs. an attention control on anxiety, lengths of stay, and opioid use in this population. Patients were eligible if they had a diagnosis of SCD, were 5-21 years old, were hospitalized for uncomplicated VOC, and had an admission pain score of ≥7. Subjects were stratified based on disease severity and randomized to the yoga or control group. Eighty-three percent of patients approached (N = 73) enrolled on study. There were no significant differences in baseline clinical or demographic factors between groups. Compared with the control group, children randomized to yoga had a significantly greater reduction in mean pain score after one yoga session (-0.6 ± 0.96 vs. 0.0 ± 1.37; P = 0.029). There were no significant differences in anxiety, lengths of stay, or opioid use between the two groups. This study provides evidence that yoga is an acceptable, feasible, and helpful intervention for hospitalized children with VOC. Future research should further examine yoga for children with SCD pain in the inpatient and outpatient settings. Copyright © 2017 American Academy of Hospice and Palliative Medicine.

    There is limited application and evaluation of health information systems in the management of vaso-occlusive pain crises in sickle cell disease (SCD) patients. This study evaluates the impact of digitization of paper-based individualized pain plans on process efficiency and care quality by examining both objective patient data and subjective clinician insights. Retrospective, before and after, mixed methods evaluation of digitization of paper documents in Children's Hospital of Pittsburgh of UPMC. Subjective perceptions are analyzed using surveys completed by 115 clinicians in emergency department (ED) and inpatient units (IP). Objective effects are evaluated using mixed models with data on 1089 ED visits collected via electronic chart review 28 months before and 22 months after the digitization. Surveys indicate that all clinicians perceived the digitization to improve the efficiency and quality of pain management. Physicians overwhelmingly preferred using the digitized plans, but only 44% of the nurses had the same response. Analysis of patient records indicates that adjusted time from analgesic order to administration was significantly reduced from 35.50 to 26.77 min (pmanagement. This study highlights the important role of health information technology (HIT) on vaso-occlusive pain management for pediatric patients with sickle cell disease and the critical challenges in accommodating human factor considerations in implementing and evaluating HIT effects.

    Full Text Available Severe vaso-occlusive retinopathy as the initial manifestation of systemic lupus erythematosus (SLE is rare. We report a 16-year-old female who developed bilateral visual impairment. Fundus examinations showed bilateral “cherry-red spot” appearance, multiple confluent cotton wool spots, and widespread arterial occlusion. Laboratory studies showed leukopenia, antinuclear antibody (+, and anti-double-stranded DNA antibody (+. Malar rashes, oral ulcers, and bilateral knee joint tenderness were noted during physical examination. SLE was diagnosed and pulse therapy started immediately. Best corrected visual acuity of the left eye improved to 6/10 after treatment. However, there was no visual improvement in the right eye. Four months later, bilateral panretinal laser photocoagulation was performed due to retinal neovascularization. However, tractional retinal detachment of the right eye and vitreous hemorrhage of the left eye still occurred. After undergoing cryoretinopexy of the right eye and intravitreous tissue plasminogen activator injection of the left eye, the visual acuity of the patient's right eye remained hand movement only at 10 cm, but that of the left eye returned to 6/10. The ocular and systemic conditions were stable in the follow-up period of more than 2 years. This case demonstrates that in patients with severe vaso-occlusive retinopathy, a generalized immunological disorder, like SLE, should be suspected.

    Sickle cell disease (SCD) is a worldwide distributed hereditary red cell disorder. The principal clinical manifestations of SCD are the chronic hemolytic anemia and the acute vaso-occlusive crisis (VOCs), which are mainly characterized by ischemic/reperfusion tissue injury. Pain is the main symptom of VOCs, and its management is still a challenge for hematologists, requiring a multidisciplinary approach. We carried out a crossover study on adult SCD patients, who received two different types of multimodal analgesia during two separate severe VOCs with time interval between VOCs of at least 6 months. The first VOC episode was treated with ketorolac (0.86 mg/kg/day) and tramadol (7.2 mg/kg/day) (TK treatment). In the second VOC episode, fentanyl buccal tablet (FBT; 100 μg) was introduced in a single dose after three hours from the beginning of TK analgesia (TKF treatment). We focused on the first 24 hours of acute pain management. The primary efficacy measure was the time-weighted-sum of pain intensity differences (SPID24). The secondary efficacy measures included the pain intensity difference (PID), the total pain relief (TOTPAR), and the time-wighted sum of anxiety (SAID24). SPID24 was significantly higher in TKF than in TK treatment. All the secondary measures were significantly ameliorated in TKF compared to TK treatment, without major opioid side effects. Patients satisfaction was higher with TKF treatment than with TK one. We propose that VOCs might require breakthrough pain drug strategy as vaso-occlusive phenomena and enhanced vasoconstriction promoting acute ischemic pain component exacerbate the continuous pain of VOCs. FBT might be a powerful and feasible tool in early management of acute pain during VOCs in emergency departments. © 2015 World Institute of Pain.

    Vaso-occlusive episodes (VOEs) are the most common complication of sickle cell disease in children. Treatment with magnesium seems to improve cellular hydration and may result in reduced vaso-occlusion. This study aimed to determine if intravenous (IV) magnesium sulfate (MgSO4) reduces length of stay (LOS) in hospital, pain scores, and cumulative analgesia when compared with placebo. Randomized, double-blind, placebo-controlled trial in children aged 4 to 18 years requiring admission to hospital with a sickle cell disease VOE requiring IV analgesia. Participating children received IV MgSO4 (100 mg/kg) every 8 hours or placebo in addition to standard therapy. We used a t test or Mann-Whitney test (continuous variables), Fisher's exact test, or χ2 test (frequencies). P values were considered significant if <.05, and 95% confidence intervals were calculated for the difference between groups. One hundred six children were randomly assigned to the study, and 104 were included. Fifty-one (49%) received MgSO4. Children's mean age was 12.4 years (range: 4-18 years; SD: 3.8 years), and 56 (54%) were females. There was no significant difference in the primary outcome measure, LOS in hospital, with a mean of 132.6 and 117.7 hours in the MgSO4 and placebo groups, respectively (P = .41). There was no significant difference between groups for the secondary outcomes of mean pain scores (4.9 ± 2.6 vs 4.8 ± 2.6, respectively; P = .92) or analgesic requirements (continuous morphine infusion [P = .928], boluses of IV morphine [P = .82], acetaminophen [P = .34], ibuprofen [P = .15], naproxen [P = .10]). Only minor adverse events were recorded in both groups. Pain at the infusion site was more common in the MgSO4 group. IV MgSO4 was well tolerated but had no effect on the LOS in hospital, pain scores, or cumulative analgesia use in admitted children with a VOE.

    Sickle cell disease has a worldwide distribution and is a public health problem in Brazil. Although vaso-occlusive crisis (VOC) is one of the most important clinical features of the disease, there are still several steps of its pathogenesis which are unknown. The increase of the chemotactic factor interleukin 8 (IL-8) has been reported to be involved in sickle cell disease crisis, but this has not been demonstrated conclusively. In the present study we analyzed serum IL-8 levels by ELISA and hematological parameters and hemoglobin patterns by standard techniques in 23 (21 SS and 2 SC) Brazilian patients with sickle cell syndromes during VOC caused by different inducing factors, 22 (21 SS and 1 SC) sickle cell patients out of crisis, and 11 healthy controls. Increased IL-8 levels were observed in 19 of 23 VOC patients (79.2%), 3 of them with more than 1,000 pg/ml. Seventeen of 22 (77.3%) non-crisis patients showed low IL-8 levels (less than 15 pg/ml). Healthy controls had low IL-8 levels. A significant difference in serum IL-8 levels was observed between crisis and non-crisis sickle cell patients (Pcrisis-inducing factor. We conclude that in the studied population, IL-8 concentration may be a useful VOC marker, although the mechanism of the pathogenic process of sickle cell VOC syndromes remains unclear.

    Full Text Available Abstract Background Asthma and sickle cell disease are common conditions that both may result in pulmonary complications. We hypothesized that children with sickle cell disease with concomitant asthma have an increased incidence of vaso-occlusive crises that are complicated by episodes of acute chest syndrome. Methods A 5-year retrospective chart analysis was performed investigating 48 children ages 3–18 years with asthma and sickle cell disease and 48 children with sickle cell disease alone. Children were matched for age, gender, and type of sickle cell defect. Hospital admissions were recorded for acute chest syndrome, cerebral vascular accident, vaso-occlusive pain crises, and blood transfusions (total, exchange and chronic. Mann-Whitney test and Chi square analysis were used to assess differences between the groups. Results Children with sickle cell disease and asthma had significantly more episodes of acute chest syndrome (p = 0.03 and cerebral vascular accidents (p = 0.05 compared to children with sickle cell disease without asthma. As expected, these children received more total blood transfusions (p = 0.01 and chronic transfusions (p = 0.04. Admissions for vasoocclusive pain crises and exchange transfusions were not statistically different between cases and controls. SS disease is more severe than SC disease. Conclusions Children with concomitant asthma and sickle cell disease have increased episodes of acute chest syndrome, cerebral vascular accidents and the need for blood transfusions. Whether aggressive asthma therapy can reduce these complications in this subset of children is unknown and requires further studies.

    Clinical trials of sickle cell disease (SCD) pain treatment usually observe only small decrements in pain intensity during the course of hospitalization. Sub-optimal analgesic management and inadequate pain assessment methods are possible explanations for these findings. In a search for better methods for assessing inpatient SCD pain in adults, we examined several pain intensity and interference measures in both arms of a randomized controlled trial comparing two different opioid PCA therapies. Based upon longitudinal analysis of pain episodes, we found that scores from daily average Visual Analogue Scales (VAS) and several other measures, especially the Brief Pain Inventory (BPI), were sensitive to change in daily improvements in pain intensity associated with resolution of vaso-occlusive pain. In this preliminary trial, the low demand, high basal infusion (LDHI) strategy demonstrated faster, larger improvements in various measures of pain than the high demand, low basal infusion (HDLI) strategy for opioid PCA dosing, however, verification in larger studies is required. The measures and statistical approaches used in this analysis may facilitate design, reduce sample size, and improve analyses of treatment response in future SCD clinical trials of vaso-occlusive episodes.

    The optimal management of recurrent painful episodes in individuals living with sickle cell disease (SCD) remains unclear. Currently, the primary treatment for these episodes remains supportive, using fluids and intravenous opioid and anti-inflammatory medications. Few reports have described the use of adjunct subanesthetic doses of ketamine to opioids for treatment of refractory pain in SCD. This article reports a retrospective case series of five patients admitted to the intensive care unit (ICU) with prolonged vaso-occlusive episodes (VOEs). Patients were treated with a continuous-infusion of low-dose ketamine (up to 5 µg/kg/min) after insufficient pain control with opioid analgesic therapy. Outcomes studied included impact on opioid analgesic use, a description of ketamine dosing strategy, and an analysis of adverse events due to opioid or ketamine analgesia. Descriptive statistics are provided. During ketamine infusion, patients experienced a lower reported pain score (mean numeric rating scale [NRS] score 7.2 vs. 6.4), reduced opioid-induced adverse effects, and decreased opioid dosing requirements (median reduction of 90 mg morphine equivalents per patient). The average duration of severe pain during admission prior to ketamine therapy was 8 days. Only one of five patients reported an adverse effect (vivid dreams) secondary to ketamine infusion. The Richmond Agitation Sedation Scale (RASS) was assessed throughout therapy, with only one patient experiencing light drowsiness. Low-dose ketamine infusion may be considered as an adjunct analgesic agent in patients with vaso-occlusive episodes who report continued severe pain despite high-dose opioid therapy, particularly those experiencing opioid-induced adverse effects.

    Sickle cell patients in acute pain situation experiment cognitive, behavioral and emotional changes that can accentuate their pain and disrupt communication with caregivers. On the other hand, caregivers have to face pain assessment difficulties and their own psychological reactions to their patient's pain. The gap between the patient's experience and caregiver's evaluation can lead to conflict and non-adherence treatment, and have a direct impact on the sickle cell disease prognosis. There is nothing inevitable about these phenomena, whose knowledge allows the action and opens up prospects for improving the management of sickle cell disease pain. This article is a narrative review updating the interactions between acute pain and some configurations, such as the inability to discern emotions, catastrophizing, post-traumatic stress or feeling ostracized. The overestimation of patient's addiction by caregivers also influences the pain itself. Open communication, as well as some treatments, medicated or not, a consistent institutional organization and a multidisciplinary approach altogether have an analgesic role by acting on pain cognitive and emotional components.

    2015-08-01

    Effective management of sickle cell pain entails a thorough understanding of its pathophysiology and the pharmacogenomics of the opioids used to manage it. In recent years, there has been significant progress along these two lines. At the pathophysiologic level, there is evidence that the severity and frequency of painful stimuli modulate their transmission at the level of the dorsal horn of the spinal cord. This modulation is achieved via two channels: the α-Amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) and NMDA receptors. Initially, the AMPA channel controls the transmission of stimuli of mild-moderate severity. Once the AMPA channel reaches its limit of membrane depolarization, the NMDA channel is activated and facilitates the transmission of painful stimuli in a progressive fashion leading to central sensitization and glial activation. At the level of pharmacogenomics, the metabolism of each opioid is patient-specific. Glucuronidation is unique for the metabolism of morphine, hydromorphone, and oxymorphone. The metabolism of all other opioids requires specific Cytochrome P450 (CYP) isoenzymes. The activity of each isoenzyme and the activity of the metabolites of each opioid vary among patients depending on their genetic makeup and coexistent environmental factors such as the use of other medications that may enhance or inhibit the CYP isoenzyme activity. © 2014 John Wiley & Sons A/S.

    Acute splenic sequestration crises are a complication of sickle cell disease, with high mortality rates and frequent recurrence in survivors of first attacks. Splenectomy and blood transfusion, with their consequences, are the mainstay of long-term management used in different parts of the world. This is a 2015 update of a Cochrane review first published in 2002, and previously updated in 2013. To assess whether splenectomy (total or partial), to prevent acute splenic sequestration crises in people with sickle cell disease, improved survival and decreased morbidity in people with sickle cell disease, as compared with regular blood transfusions. We searched the Cochrane Cystic Fibrosis and Genetic Disorders Group Haemoglobinopathies Trials Register, which comprises of references identified from comprehensive electronic database searches and handsearching relevant journals and abstract books of conference proceedings.Additional trials were sought from the reference lists of the trials and reviews identified by the search strategy.Date of the most recent search: 10 June 2015. All randomized or quasi-randomized controlled trials comparing splenectomy (total or partial) to prevent recurrence of acute splenic sequestration crises with no treatment or blood transfusions in people with sickle cell disease. No trials of splenectomy for acute splenic sequestration were found. No trials of splenectomy for acute splenic sequestration were found. Splenectomy, if full, will prevent further sequestration and if partial, may reduce the recurrence of acute splenic sequestration crises. However, there is a lack of evidence from trials showing that splenectomy improves survival and decreases morbidity in people with sickle cell disease. There is a need for a well-designed, adequately-powered, randomized controlled trial to assess the benefits and risks of splenectomy compared to transfusion programmes, as a means of improving survival and decreasing mortality from acute splenic

    This pilot study was conducted to determine the effectiveness of Healing Touch on anxiety, stress, pain, pain medication usage, and selected physiological measures of hospitalized adults with sickle cell disease experiencing a vaso-occlusive pain episode. Healing Touch sessions were administered for 30 minutes on four consecutive days, and the self-reported data on anxiety, stress, pain, and the selected physiological data were collected while controlling for music and presence. A parallel-group randomized control trial comparing the effects of Healing Touch with Music (HTM) to Attention Control with Music (ACM). Due to the small sample size, there were no statistically significant changes in any between-group comparisons, except for present pain on Day 4 for the ACM group. For both groups, the within-group comparison showed a nonsignificant reduction in physiological parameters, a statistically significant reduction in anxiety and stress for the ACM group after Day 4, and a statistically significant reduction in stress in the HTM group after Days 2 and 4. The pre- to postintervention reductions in present pain were greater in the HTM group across all 4 days, but the only statistically significant within groups findings were in the HTM group (p < .01) on Day 1. Further research is needed.

    Sickle cell disease is a chronic hematologic disease with a variety of acute, and often recurring, complications. Vaso-occlusive crisis, a unique but common presentation in sickle cell disease, can be challenging to manage. Acute chest syndrome is the leading cause of death in patients with sickle cell disease, occurring in more than half of patients who are hospitalized with a vaso-occlusive crisis. Uncommon diagnoses in children, such as stroke, priapism, and transient red cell aplasia, occur more frequently in patients with sickle cell disease and necessitate a degree of familiarity with the disease process and its management. Patients with sickle cell trait generally have a benign course, but are also subject to serious complications. This issue provides a current review of evidence-based management of the most common acute complications of sickle cell disease seen in pediatric patients in the emergency department.

    Sickle cell disease is characterized by chronic hemolytic anemia and vaso-occlusive painful crises. The vascular occlusion in sickle cell disease is a complex process and accounts for the majority of the clinical manifestation of the disease. Abdominal pain is an important component of vaso-occlusive painful crises. It often represents a substantial diagnostic challenge in this population of patients. These episodes are often attributed to micro-vessel occlusion and infarcts of mesentery and abdominal viscera. Abdominal pain due to sickle cell vaso-occlusive crisis is often indistinguishable from an acute intra-abdominal disease process such as acute cholecystitis, acute pancreatitis, hepatic infarction, ischemic colitis and acute appendicitis. In the majority of cases, however, no specific cause is identified and spontaneous resolution occurs. This chapter will focus on etiologies, pathophysiology and management of abdominal pain in patients with sickle cell disease.

    Finding the most appropriate strategy for the prevention of moderate acute malnutrition (MAM) and severe acute malnutrition (SAM) in young children is essential in countries like Niger with annual "hunger gaps." Options for large-scale prevention include distribution of supplementary foods, such as fortified-blended foods or lipid-based nutrient supplements (LNSs) with or without household support (cash or food transfer). To date, there has been no direct controlled comparison between these strategies leading to debate concerning their effectiveness. We compared the effectiveness of seven preventive strategies-including distribution of nutritious supplementary foods, with or without additional household support (family food ration or cash transfer), and cash transfer only-on the incidence of SAM and MAM among children aged 6-23 months over a 5-month period, partly overlapping the hunger gap, in Maradi region, Niger. We hypothesized that distributions of supplementary foods would more effectively reduce the incidence of acute malnutrition than distributions of household support by cash transfer. We conducted a prospective intervention study in 48 rural villages located within 15 km of a health center supported by Forum Santé Niger (FORSANI)/Médecins Sans Frontières in Madarounfa. Seven groups of villages (five to 11 villages) were allocated to different strategies of monthly distributions targeting households including at least one child measuring 60 cm-80 cm (at any time during the study period whatever their nutritional status): three groups received high-quantity LNS (HQ-LNS) or medium-quantity LNS (MQ-LNS) or Super Cereal Plus (SC+) with cash (€38/month [US$52/month]); one group received SC+ and family food ration; two groups received HQ-LNS or SC+ only; one group received cash only (€43/month [US$59/month]).

    The author's aim was to give very precise information on the many causes and effects of the oil crises that have occurred since 1900, and at the same time offer the reader the possibility to build up a basic knowledge of the oil industry and market, as he feels that the public is often subjected to misleading information. Political and economical aspects are elaborated. First-hand sources such as statistics and investigations have been used as far as possible to give information on the oil market. An oil crisis is defined by the author as a significant change in the price of oil compared to prices of other goods. Changes can be in the form of either rising or falling prices. A special chapter concentrates on Denmark in relation to the oil crises. (AB) (165 refs.)

    Acute, vaso-occlusive pain is the most characteristic complication of sickle cell disease (SCD). Although there has been rigorous work examining the pathogenesis of vaso-occlusion, fewer studies have focused on approaches to the clinical management of acute pain. In this review, we will examine the epidemiology and management strategies of acute pain events and we will identify limitations in the best available studies. Most acute pain events in adults with SCD are managed at home without physician contact. Prior descriptions of the natural history of pain episodes from the Cooperative Study of Sickle Cell Disease relied on physician contact, limiting the generalizability of these findings to current practice. Patient-controlled analgesia has replaced on-demand therapy to become the standard for management of severe pain events in children and adults with SCD requiring hospital admission. Unfortunately, most clinical practice guidelines for the management of acute pain are not based on randomized clinical trials. As a result, our practice of pain management is primarily limited to expert opinion and inferences from observational studies. Additional clinical trials in management of acute pain in children and adults with SCD are critical for the development of evidence-based guidelines.

    Aim: To prove the hypothesis that acute bone infarcts in sickle cell disease are caused by sequestration of red blood cells (RBCs) in bone marrow, and to evaluate the unenhanced T1 fat-saturated (fs) sequence in the differentiation of acute bone infarction from acute osteomyelitis in patients with sickle-cell disease. Materials and methods: Two studies were undertaken: an experimental study using in-vitro packed red blood cells and normal volunteers, and a retrospective clinical study of 86 magnetic resonance imaging (MRI) studies. For the experimental study containers of packed RBCs were placed between the knees of four healthy volunteers with a saline bag under the containers as an additional control, and were scanned with the pre-contrast T1-fs sequence. Signal intensity (SI) ratios were obtained for packed RBCs:skeletal muscle and packed RBCs:saline. For the clinical study, the SIs of normal bone marrow, packed RBCs, bone and/or soft-tissue lesions, and normal skeletal muscle of 74 patients (86 MRI studies) were measured using unenhanced, T1 fat-saturated MRI. The ratios of the above SIs to normal skeletal muscle were calculated and subjected to statistical analysis. Results: Fifty-one of 86 MRI studies were included in the final analysis. The ratios of SIs for normal bone marrow, packed red cells, bone infarction, acute osteomyelitis, and soft-tissue lesions associated with bone infarct, compared with normal skeletal muscle were (mean ± SD) 0.9 ± 0.2, 2.1 ± 0.7, 1.7 ± 0.5, 1.0 ± 0.3, and 2.2 ± 0.7, respectively. The difference in the ratio of SIs of bone infarcts and osteomyelitis was significant (p = 0.003). The final diagnoses were bone infarction (n = 50), acute osteomyelitis (n = 1), and co-existent bone infarction and osteomyelitis (n = 2). Seven patients who had suspected osteomyelitis underwent image-guided aspiration. Conclusion: Acute bone infarcts in sickle cell disease are caused by sequestration of red blood cells in the bone marrow. The

    We provide among the first empirical evidence consistent with recent macro global-game crisis models, which show that the precision of public signals can coordinate crises (e.g., Angeletos and Werning, 2006; Morris and Shin, 2002, 2003). In these models, self-fulfilling crises (independent of poor fundamentals) can occur only when publicly disclosed signals of fundamentals have high precision; poor fundamentals are the sole driver of crises only in low precision settings. We find evidence con...

    The complexity of providing medical care in a high-tech environment with a highly specialized, limited labour force makes hospitals more crisis-prone than other industries. An effective defence against crises is only possible if the organizational resilience and the capacity to handle crises become part of the hospitals' organizational culture. To become more resilient to crises, a raised awareness--especially in the area of human resource (HR)--is necessary. The aim of this paper is to contribute to the process robustness against crises through the identification and evaluation of relevant HR crises and their causations in hospitals. Qualitative and quantitative methods were combined to identify and evaluate crises in hospitals in the HR sector. A structured workshop with experts was conducted to identify HR crises and their descriptions, as well as causes and consequences for patients and hospitals. To evaluate the findings, an online survey was carried out to rate the occurrence (past, future) and dangerousness of each crisis. Six HR crises were identified in this study: staff shortages, acute loss of personnel following a pandemic, damage to reputation, insufficient communication during restructuring, bullying, and misuse of drugs. The highest occurrence probability in the future was seen in staff shortages, followed by acute loss of personnel following a pandemic. Staff shortages, damage to reputation, and acute loss of personnel following a pandemic were seen as the most dangerous crises. The study concludes that coping with HR crises in hospitals is existential for hospitals and requires increased awareness. The six HR crises identified occurred regularly in German hospitals in the past, and their occurrence probability for the future was rated as high.

    Full Text Available Sickle cell disease (SCD is an autosomal recessive hemoglobinopathy that causes significant morbidity and mortality related to chronic hemolytic anemia, vaso-occlusion, and resultant end-organ damage. Tobacco smoke exposure (TSE through secondhand smoke exposure in people with SCD of all ages and through primary smoking in adolescents and adults is associated with significantly increased morbidity, with increased rates of emergency department visits and hospitalizations for painful vaso-occlusive crises and acute chest syndrome (ACS. Secondhand smoke is also associated with pulmonary function abnormalities in children with SCD who are already at risk for pulmonary function abnormalities on the basis of SCD. TSE is emerging as one of the few modifiable risk factors of SCD. This review discusses the current state of the evidence with respect to TSE and SCD morbidity, discusses potential mechanisms, and highlights current gaps in the evidence and future research directions.

    Extensive media coverage is warning of a crisis of trust that has emerged as a serious issue in our society. This article explores the meaning of "crisis," concepts of crisis management, mechanisms for building trust, and the underlying significance of trust and distrust. Evidence is adduced to testify to the erosion of trust and factors in our society that reflect the potential for crises of trust. Organizational decision makers, including hospital managers, are urged to identify and reflect upon weaknesses in their organizations in order that remedial action can be taken to preempt such crises.

    Full Text Available This paper studies the factors associated with the emergence of banking crises and currency crises and the interrelationship between the two crises in 21 American, European and Asian countries in 1973~2000 using a multivariate logit econometric model. And this analysis attempts to introduce the lag model to solve the causality problems in banking crises and currency crises. In case of the simple binary models without lag, banking crises were associated with economic recession, inflation, depreciation, the rise of real interest rate, lending boom. But in case of lag models, banking crises were caused by economic recession, inflation, the rise of real interest rate, lending boom, the rise of reserve ratio, the liberalization of capital account. Currency crises were associated with economic recession, the larger deficit of current account relative to import in case of the simple binary models without lag, But in case of lag models, currency crises were caused by economic recession, the rapid decrease of net foreign assets of banks, and the larger deficit of current account relative to import. And this analysis shows that currency crises can be a cause of banking crises, not vice versa. Nevertheless the two types of crises have positive correlation with each other.

    Recently, the Trend Analysis Program (TAP) of the American Council of Life Insurance commissioned the Futures Group of Glastonbury, Connecticut, to examine the potential for large-scale catastrophic events in the near future. TAP was specifically concerned with five potential crises: the warming of the earth's atmosphere, the water shortage, the collapse of the physical infrastructure, the global financial crisis, and the threat of nuclear war. We are often unprepared to take action; in these cases, we lose an advantage we might have otherwise had. This is the whole idea behind forecasting: to foresee possibilities and to project how we can respond. If we are able to create forecasts against which we can test policy options and choices, we may have the luxury of adopting policies ahead of events. Rather than simply fighting fires, we have the option of creating a future more to our choosing. Short descriptions of these five potential crises and, in some cases, possible solutions are presented

    Suicides among men aged 35-64 years increased by 27% between 1999 and 2013, yet little research exists to examine the nature of the suicide risk within this population. Many men do not seek help if they have mental health problems and suicides may occur in reaction to stressful circumstances. We examined the precipitating circumstances of 600 suicides without known mental health or substance abuse (MH/SA) problems and with a recent crisis. Whether these suicides occurred within the context of an acute crisis only or in the context of chronic circumstances was observed. Using data from the National Violent Death Reporting System and employing mixed-methods analysis, we examined the circumstances and context of a census of middle-aged male suicides (n = 600) in seven states between 2005 and 2010. Precipitating circumstances among this group involved intimate partner problems (IPP; 58.3%), criminal/legal problems (50.7%), job/financial problems (22.5%), and health problems (13.5%). Men with IPP and criminal/legal issues were more likely than men with health and/or job/financial issues to experience suicide in the context of an acute crisis only. Suicides occurring in reaction to an acute crisis only or in the context of acute and chronic circumstances lend themselves to opportunities for intervention. Further implications are discussed.

    Full Text Available Timely, provocative, and theoretically sophisticated, the essays comprising In the Face of Crises: Anglophone Literature in the Postmodern World situate their work amid several critical global concerns: the devastation wreaked by global capitalism following the worldwide financial crash, the financial sector’s totalizing grip upon the world economy, the challenge to traditional definitions of “human nature” and identity posed by technologies of the body and of warfare, the quest of indigenous communities for healing from the continuing traumatic effects of colonization, and the increasing corporatization of the academy as an apparatus of the neo-liberal state – to specify only a few. Edited by Professors Ljubica Matek and Jasna Poljak Rehlicki, these essays deploy a broad range of contemporary theories, representing recent developments in cultural studies, the new economic criticism, postcolonial film studies, feminism and gender studies, and the new historicism. The eleven essays selected by Matek and Rehlicki offer convincing support for their claim that humanistic research delving into Anglophone literature, far from being a “non-profitable” pursuit in an increasingly technologized society, affords clarifying insights into contemporary “economic, cultural, and social processes in the globalizing and globalized culture of the West” (ix.

The first pattern is that crises result in an intensification of women's work, especially the unpaid care work. The second one is that after economic crises male employment recovery is always previous to the female employment, which always ends even more precarious; and the third pattern is that crisis lead to setbacks in the advances made in gender equality in terms of regulation, equality policies and the rules of the game in general.

    Bone crises in type 1 Gaucher disease are reported in long bones and occasionally in weight bearing bones and other bones, but rarely in small bones of the hands and feet. We retrospectively examined the incidence of bone pain in patients followed at the Rabin Medical Center, Israel, before and following the initiation of enzyme replacement therapy (ERT) and evaluated them for bone crises. Of 100 type I Gaucher disease patients, 30 (30%) experienced one or more bone crises. Small bone crises represented 31.5% of all bone crises and were always preceded by crises in other bones. While the incidence of long bone crises reduced after the initiation of ERT, small bone crises increased. Almost 60% of patients with bone crises were of the N370S/84GG genotype suggesting a greater susceptibility of N370S/84GG patients to severe bone complications. These patients also underwent the greatest number of splenectomies (70.6% of splenectomised patients). Splenectomised patients showed a trend towards increased long and small bone crises after surgery. Active investigation of acute pain in the hands and feet in patients in our cohort has revealed a high incidence of small bone crises. Physicians should consider imaging studies to investigate unexplained pain in these areas. Copyright © 2015 Elsevier Inc. All rights reserved.

A published report by Lazarou et al in 1998 showed that adverse drug events were the 4th to 6th leading cause of death in the United States. These events may lead to drug safety crises in some issues, which need to take crises management process for solving the problem and/or preventing similar events.Objectives: To evaluate nature of drug safety crises based on adverse events reported to Iranian Pharmacovigilance Center from 1999 through 2012. To mention success and failure outcomes of crises management process taken against detected crises.Methods: All adverse drug events received by Iranian Pharmacovigilance Center from 1999 through 2012 were evaluated for reports with fatal outcome. All alerting letters and manuscripts published by the Center during the same period were reviewed for detailed information on detected crises. World Health Organization definition was used for detecting drug safety crises.Results: Among 42036 registered cases in our database, 463 deaths were recorded. The most frequent suspected drug for adverse events with fatal outcome was ceftriaxone (100 cases. Ten different drug safety crises issues were detected during the study period and their successful or failure outcomes were evaluated. There were 112 issued alerting letters and 17 published manuscript during the same period which was monitored for detailed information.  Conclusion: It is necessary for national pharmacovigilance centers to have prepared programs for crises management. This could be useful for reducing drug related mortality.

The paper posits that legitimation crises are a recurring problem in world-systems and have led to collapse in a number of cases. Prehistoric North American and Pacific world-systems are used as examples.

    Full Text Available We extended the Cole and Kehoe model (1996 by adding trade and debt denominated in national currency. We then evaluated some external debt defaults and steep national currency devaluations occurred during last decades. Although default is unlikely, steep devaluation has been repeatedly triggered during financial distresses. It helps to overcome financial crisis as it improves trade balance and reduces national debt level. On the other hand, expected devaluation hurts welfare through both higher national debt cost and reductions in the investment level. We modeled such trade-offs and showed that trade openness, by and large, improves the expected welfare as it allows for a better devaluation-response technology. We ran model simulations based on past 48 crises occurred in 32 middle-income countries, reasonably fitting devaluation and default responses observed as from 1971.

    The growing dependency of Europe as a whole on energy imports and anticipated further increases in energy prices reinforce the concerns about meeting the energy demand in the future. The objective of the Study is to identify the threats leading to potential energy crises and suggest solutions for facing, in an appropriate way, the related key challenges. In addition, the Study intends to develop a number of indicators effective enough to assess the level of different types of vulnerability, as well the overall vulnerability of a country or region, including threats to physical disruption, higher energy prices etc. The use of vulnerability indicators is highly recommended for all WEC-European countries, as well as to policy makers and market players.

    This short paper argues that the view that monetary policy is ineffective during financial crises is not only wrong, but may promote policy inaction in the face of a severe contractionary shock. To the contrary, monetary policy is more potent during financial crises because aggressive monetary policy easing can make adverse feedback loops less likely. The fact that monetary policy is more potent than during normal times provides a rationale for a risk-management approach to counter the contra...

  10. Population crises and population cycles.

    Science.gov (United States)

    Russell, C; Russell, W M

    2000-01-01

    To prevent a population irretrievably depleting its resources, mammals have evolved a behavioural and physiological response to population crisis. When a mammalian population becomes dangerously dense, there is a reversal of behaviour. Co-operation and parental behaviour are replaced by competition, dominance and aggressive violence, leading to high mortality, especially of females and young, and a reduced population. The stress of overpopulation and the resulting violence impairs both the immune and the reproductive systems. Hence epidemics complete the crash of the population, and reproduction is slowed for three or four generations, giving the resources ample time to recover. In some mammal species, crisis and crisis response recur regularly, leading to cycles of population growth and relapse, oscillating about a fixed mean. Population crisis response and population cycles have been equally prominent in the history of human societies. But in man successive advances in food production have made possible growing populations, though with every such advance population soon outgrew resources again. Hence human cycles have been superimposed on a rising curve, producing a saw-tooth graph. Because advances in food production amounted to sudden disturbances in the relations between human populations and their environments, the crisis response in man has failed to avert famine and resource damage. In the large human societies evolved since the coming of settled agriculture and cities, the basic effects of violence, epidemics, famine and resource damage have been mediated by such specifically human disasters as inflation, unemployment, and political tyranny. An account of past crises, periods of relative relief from population pressure, and resulting cycles, is given for a number of regions: China, North Africa and Western Asia, the northern Mediterranean, and north-western Europe. The paper ends with an account of the present world-wide population crisis, and the solution

    The kidney is frequently affected in patients with sickle cell syndrome, i.e., homozygous and heterozygous patients, with a consequently large spectrum of renal abnormalities that may range from minimal functional changes to chronic renal failure. Here, we present a 13-year-old boy with sickle cell anemia (SCA) (HbSS) who was referred to our unit with nephrotic syndrome. Renal biopsy revealed AA type amyloidosis on the basis of light microscopic findings, indicating Congo red staining and immunohistochemistry. He had neither a family history of familial Mediterranean fever (FMF) nor any complaint of recurrent abdominal pain, arthritis, and fever, but frequent painful vaso-occlusive crises. The patient was found to have no MEFV gene (Mediterranean feVer) mutations either. Painful episodic attacks might provoke recurrent acute inflammation, leading to repeated stimulation of acute phase responses and cause secondary amyloidosis. To our knowledge, this boy is the first case of SCA complicated by renal amyloidosis observed in childhood.

    Full Text Available Deborah R Stein, Michael A Ferguson Division of Nephrology, Boston Children's Hospital, Harvard Medical School, Boston, MA, USA Abstract: Hypertensive crises in children are medical emergencies that must be identified, evaluated, and treated promptly and appropriately to prevent end-organ injury and even death. Treatment in the acute setting typically includes continuous intravenous antihypertensive medications with monitoring in the intensive care unit setting. Medications commonly used to treat severe hypertension have been poorly studied in children. Dosing guidelines are available, although few pediatric-specific trials have been conducted to facilitate evidence-based therapy. Regardless of what medication is used, blood pressure should be lowered gradually to allow for accommodation of autoregulatory mechanisms and to prevent cerebral ischemia. Determining the underlying cause of the blood pressure elevation may be helpful in guiding therapy.

    In order to evaluate the role of gadolinium-DOTA enhanced MRI in the management of painful osseous crises in children with sickle cell anemia (SCA), nine children with SCA underwent MRI, bone scans and ultrasonographic studies during 11 osseous crises. Imaging findings were compared with the final diagnosis: three acute osteomyelitis (AO) and 16 acute infarcts (AI). MRI could not differentiate AO from AI. The appearance of severe AI was very misleading and was similar to the usual appearance of AO, including soft tissue changes, periosteal reaction and patterns of enhancement. Gadolinium-DOTA enhanced MRI was useful for determining the anatomic site and extent of AO or AI and for distinguishing between necrotic material, fluid collection and vascularized inflammatory tissue. It can also help to guide the aspiration of intraosseous, subperiosteal and soft tissue fluid collections. (orig.)

    2011-12-01

    Full Text Available The fundamental idea of International capital flows is that short-term flows can be easily reversed, while flows on a longer time horizon are more stable. Crises are associated with withdrawals of short-term capital flows and growth of the foreign direct investment flows. The current crisis has meant a major decline of international capital flows, also of the foreign direct investment. The analysis in this article tries to establish if and under which conditions foreign direct investments can bring greater stability during the crisis, comparing the evolution of foreign direct investments in the current crisis with their response in previous crises. We show that during previous crises foreign direct investments were stable, behaving differently from other types of capital. Yet, during the current crisis, foreign direct investments have proven to be not so stable and all the components declined, raising questions about the resumption of the positive trend. The stability of foreign direct investments in the past was given by the increase of mergers and acquisitions during the crisis, reflecting fire-sale FDI. This feature is not found in the current crisis as mergers and acquisitions were severe affected by the crises and recorded a major decline.

  5. International experiences with power supply crises

    International Nuclear Information System (INIS)

    2002-01-01

    Many so-called deregulated power markets experience a hardened energy and power balance and some have had supply crises. This report discusses the crises, their impacts and their causes as well as the measures taken by the authorities to solve the crises. It also considers the similarities or dissimilarities with respect to the situation in Norway the winter 2002/2003. Like Norway, many of the countries have a considerable share of hydroelectric power. It is found, however, that the dependence on water of its own is not the reason for the crises, but that the inflow conditions give the market greater challenges. Furthermore, the Norwegian market has greater flexibility in the consumption, greater import capacity, better price security possibilities and less problems with market power than most of the countries here considered. Various factors influence a country's power consumption and production capacity. Economic growth and the availability of inexpensive power contribute to accelerate the consumption, while predictable external conditions and sufficient expected investment earnings are necessary to achieve an increase of the capacity - both through new investments and attendance to existing capacity. In a smooth power market there must be a certain correspondence between consumption and installed capacity, and the capacity must be such that it can cover the continuous demand for power and at the same time be flexible enough to deliver power at peak loads. This is also true of the transmission capacity. In addition, some extra capacity must be available for unexpected events. The basic problem is, in any power market, that the consumption may rise fast, while the investments in new capacity typically occurs in leaps, with long and costly construction phases. Many countries have lately experienced a hardening of the balance between consumption and capacity and so have been vulnerable to unexpected increases in consumption or resource failure. This was also the

    2011-01-01

    This is a case of a 2-year-old boy with sickle cell disease who presented with bilateral eyelid swelling, limited extraocular motility, and lateral subperiosteal fluid collection associated with bilateral lateral orbital wall infarctions on MRI. The patient was managed medically with intravenous fluids, analgesics, broad-spectrum antibiotics, systemic steroids, and clinically improved. Patients with sickle cell disease are susceptible to infarction of the orbital bones during vaso-occlusive crises. Orbital wall infarction can lead to acute proptosis and restricted extraocular motility. Orbital wall infarction should be considered in sickle cell patients with orbital diseases so that appropriate treatment can be instituted promptly to prevent the serious sequelae of orbital compression syndrome.

    Full Text Available In this paper we are looking at the cause-effect relationship between the economic, financial, demographic and food crises. Crises are interrelated and need to be viewed together, as the effects of one crisis are or may represent causes for another crisis. The current food crisis translates today in food price increases, in the level of health of the population that does not have enough resources for a balanced diet and in obesity problems of the young generation (Romania ranks third among European countries. All these issues with immediate and direct effects over the population in our country have generated our interest to conduct a rigorous and careful observation on the development of the phenomenon of food crisis. Food crisis, its causes and consequences – aging population, the migration of the active population to other countries (especially from the rural areas and the agglomeration of the disadvantaged population in certain geographical areas, can cause social and economic imbalances.

  8. Stochastic Modeling of Past Volcanic Crises

    Science.gov (United States)

    Woo, Gordon

    2018-01-01

    The statistical foundation of disaster risk analysis is past experience. From a scientific perspective, history is just one realization of what might have happened, given the randomness and chaotic dynamics of Nature. Stochastic analysis of the past is an exploratory exercise in counterfactual history, considering alternative possible scenarios. In particular, the dynamic perturbations that might have transitioned a volcano from an unrest to an eruptive state need to be considered. The stochastic modeling of past volcanic crises leads to estimates of eruption probability that can illuminate historical volcanic crisis decisions. It can also inform future economic risk management decisions in regions where there has been some volcanic unrest, but no actual eruption for at least hundreds of years. Furthermore, the availability of a library of past eruption probabilities would provide benchmark support for estimates of eruption probability in future volcanic crises.

Economic theory has to be radically reinvented to squarely face the reality of rising unemployment, widening inequalities, growing ecological threats, frustrated social aspirations and unmet human needs. Monetary and fiscal policies are too crude and insufficient to steer the essential change of course required to address multidimensional demographic, ecological, economic, political and social crises. New values are needed to guide policy formulation and new institutions are needed to support peaceful social evolution and inclusive, equitable development in an increasingly globalized and interconnected world.

    Highlights: • We studied a dissipative bouncing ball dynamics. • A two-dimensional nonlinear mapping describes the dynamics. • Crises between attractors and its manifolds were characterized. • A new physical crisis between vibrating platform and an attractor was characterized. • The existence of a ‘robust’ chaotic attractor was set. - Abstract: The dynamics of a bouncing ball model under the influence of dissipation is investigated by using a two-dimensional nonlinear mapping. When high dissipation is considered, the dynamics evolves to different attractors. The evolution of the basins of the attracting fixed points is characterized, as we vary the control parameters. Crises between the attractors and their boundaries are observed. We found that the multiple attractors are intertwined, and when the boundary crisis between their stable and unstable manifolds occurs, it creates a successive mechanism of destruction for all attractors originated by the sinks. Also, a physical impact crisis is described, an important mechanism in the reduction of the number of attractors.

    Full Text Available No contexto de elevada incerteza decorrente da crise econômica mundial, é inevitável que surjam comparações entre o momento atual e a experiência dramática da Grande Depressão, que subverteu o mundo entre 1929 e 1933. Mas, apesar das perdas financeiras e da desaceleração da economia, a disposição para a intervenção estatal é hoje um elemento determinante que diferencia nitidamente as iniciativas da política econômica. Este é um fator decisivo que projeta um futuro menos sombrio para a evolução da crise atual.In the current context of high uncertainty, many parallels have been traced between the economic crisis of 2008 and the Great Depression, that stirred the world between 1929 e 1933. However, despite the financial losses that recently occurred, the disposition for state intervention in our days is much higher and thus an important element in the formulation of economic policies. This is a difference that suggests a less catastrophic outcome to the current crisis.

    Research has suggested that interprofessional collaboration could improve patient outcomes in the intensive care unit (ICU). Maintaining optimal interprofessional interactions in a setting where unpredictable medical crises occur periodically is however challenging. Our study aimed to investigate the perceptions of ICU health care professionals regarding how acute medical crises affect their team interactions. We conducted 25 semi-structured interviews of ICU nurses, staff physicians, and respiratory therapists. All interviews were audio-taped and transcribed, and the analysis was undertaken using an inductive thematic approach. Our data indicated that the nature of interprofessional interactions changed as teams passed through three key temporal periods around medical crises. During the "pre-crisis period", interactions were based on the mutual respect of each other's expertise. During the "crisis period", hierarchical interactions were expected and a certain lack of civility was tolerated. During the "post-crisis period", divergent perceptions emerged amongst health professionals. Post-crisis team dispersion left the nurses with questions and emotions not expressed by other team members. Nurses believed that systematic interprofessional feedback sessions held immediately after a crisis could address some of their needs. Further research is needed to establish the possible benefits of strategies addressing ICU health care professionals' specific needs for interprofessional feedback after a medical crisis.

    Full Text Available Capital flows are responsible for a strong influence on the foreign exchange rates and stock prices macroeconomic parameters. In volatile economies, capital flows can change due to several types of social, political and economic events, provoking oscillations on these parameters, which are recognized as economic crises. This work aims to investigate how these two macroeconomic variables are related with crisis events by using the traditional complex measures due to Lopez-Mancini-Calbet (LMC and to Shiner-Davison-Landsberg (SDL, that can be applied to any temporal series. Here, Ibovespa (Bovespa Stock Exchange main Index and the "dollar-real" parity are the background for calculating the LMC and SDL complexity measures. By analyzing the temporal evolution of these measures, it is shown that they might be related to important events that occurred in the Brazilian economy.

    We describe a rare, severe, vaso-occlusive presentation of sickle cell disease, named sickle cell intrahepatic cholestasis (SCIC). Patients with sickle cell/β + thalassaemia frequently have mild vaso-occlusive symptoms and only one case of SCIC developing in a patient with sickle cell/β + thalassaemia has been previously described in the world literature. The present report represents only the second described case of SCIC in a patient with sickle cell/β + thalassaemia. An abdominal computed tomography scan and Doppler ultrasound studies demonstrated massive hepatomegaly (25 cm span). Liver biopsy was performed and demonstrated dilatation and congestion of erythrocytes, severe cholestasis and fibrosis. The case demonstrates the importance of early recognition and institution of adequate therapy. Initial and correct diagnosis does not require biopsy or surgery which carry substantial risks of bleeding and mortality

    Full Text Available Crises are never convenient as they are destructive. Any institution or organization may face a crisis situation, able to endanger its normal activity and reputation. Some crises are predictable and can be prevented, others cannot be grasped and thus prevented. Experience proved that, despite all technical, economical, financial or educational cautions taken to stop or control a crisis, it can get out of control and develop. In these circumstances, the crisis can bring serious prejudices to the organization if not properly managed from all points of view. Communication during crisis is extremely important, aiming at generating changes and taking action against the crisis. Above all, crises management consists in interpersonal relations. Management activity in crises situations develops a constant and complex communication process with the aid of which, the manager, the crisis cell, the entire staff interact in order to find the optimal strategies to survive the crisis situation.

    Sound scientific management of volcanic crises is the primary tool to reduce significantly volcanic risk in the short-term. At present, a wide variety of qualitative or semi-quantitative strategies is adopted, and there is not yet a commonly accepted quantitative and general strategy. Pre-eruptive processes are extremely complicated, with many degrees of freedom nonlinearly coupled, and poorly known, so scientists must quantify eruption forecasts through the use of probabilities. On the other hand, this also forces decision-makers to make decisions under uncertainty. We review the present state of the art in this field in order to identify the main gaps of the existing procedures. Then, we put forward a general quantitative procedure that may overcome the present barriers, providing guidelines on how probabilities may be used to take rational mitigation actions. These procedures constitute a crucial link between science and society; they can be used to establish objective and transparent decision-making protocols and also clarify the role and responsibility of each partner involved in managing a crisis.

    Full Text Available Different scientific studies provide many valuable recommendations how to manage crises in order to lessen their negative effect on relations with consumers. But the question whether the same business crises management rules can be applied for different industries, or they must be adapted depending on industries specifics, has not received sufficient scientific attention. Knowledge gaps about industry specific effect on consumer reactions to business crises remain. This study focuses on understanding the differences in consumers’ reactions in business crises situations with regard to controversial evaluation in the society of “the sin industries” (alcohol, tobacco, gambling, etc. and ordinary industries (not having controversial associations. Experimental research design, including online experiment with tobacco, beer and functional soft drinks consumers (in total 306 respondents, was chosen for competing research hypotheses testing. Empirical evidence was in line with theoretical argumentation about less negative consumers’ reactions during business crises in case of “sin industries” versus ordinary industry. This study shows that consumers attitudes, such as perception of company’s product quality, trust, social responsibility and behavioural intentions, such as intention to buy and recommend company’s products, are less negative during business crises in lower reputation “sin industries” than in ordinary industries.

    To further our understanding of how to enhance student science and risk communication skills in natural hazards and earth science courses, we conducted a pilot study to assess the different perceptions of expert scientists and risk communication practitioners versus the perceptions of students. These differences will be used to identify expert views on best practice, and improve the teaching of communication skills at the University level. In this pilot study, a perceptions questionnaire was developed and validated. Within this, respondents (geoscientists, engineers, and emergency managers; n=44) were asked to determine their agreement with the use and effectiveness of specific communication strategies (within the first 72 hours after a devastating earthquake) when communicating to the public. In terms of strategies and information to the public, the respondents were mostly in agreement, but there were several statements which elicited large differences between expert responses: 1) the role and purpose of the scientific communication during crises (to persuade people to care, to provide advice, to empower people to take action); 2) the scientist's delivery (showing the scientists emotions and enthusiasm for scientific concepts they are discussing); and 3) the amount of data that is discussed (being comprehensive versus 'only the important' data). The most disagreed upon dimension was related to whether to disclose any political influence on the communication. Additionally, scientists identified that being an effective communicator was an important part of their job, and agreed that it is important to practice these skills. Respondents generally indicated that while scientists should be accountable for the science advice provided, they should not be held liable.

  5. Role of the police in linking individuals experiencing mental health crises with mental health services

    Science.gov (United States)

    2012-01-01

    Background The police are considered frontline professionals in managing individuals experiencing mental health crises. This study examines the extent to which these individuals are disconnected from mental health services, and whether the police response has an influence on re-establishing contact. Methods Police records were searched for calls regarding individuals with acute mental health needs and police handling of these calls. Mental healthcare contact data were retrieved from a Psychiatric Case Register. Results The police were called upon for mental health crisis situations 492 times within the study year, involving 336 individuals (i.e. 1.7 per 1000 inhabitants per year). Half of these individuals (N=162) were disengaged from mental health services, lacking regular care contact in the year prior to the crisis (apart from contact for crisis intervention). In the month following the crisis, 21% of those who were previously disengaged from services had regular care contact, and this was more frequent (49%) if the police had contacted the mental health services during the crisis. The influence of police referral to the services was still present the following year. However, for the majority (58%) of disengaged individuals police did not contact the mental health services at the time of crisis. Conclusions The police deal with a substantial number of individuals experiencing a mental health crisis, half of whom are out of contact with mental health services, and police play an important role in linking these individuals to services. Training police officers to recognise and handle mental health crises, and implementing practical models of cooperation between the police and mental health services in dealing with such crises may further improve police referral of individuals disengaged from mental health services.

    Given the growing scale and complexity of responses to humanitarian crises, it is important to develop a stronger evidence base for health interventions in such contexts. Humanitarian crises present unique challenges to rigorous and effective research, but there are substantial opportunities for scientific advance. Studies need to focus where the translation of evidence from noncrisis scenarios is not viable and on ethical ways of determining what happens in the absence of an intervention. Robust methodologies suited to crisis settings have to be developed and used to assess interventions with potential for delivery at scale. Strengthening research capacity in the low- to middle-income countries that are vulnerable to crises is also crucial. Copyright © 2014, American Association for the Advancement of Science.

    Stosic, Darko; Stosic, Dusan; Ludermir, Teresa; de Oliveira, Wilson; Stosic, Tatijana

    2016-05-01

    This paper examines the effects of financial crises on foreign exchange (FX) markets, where entropy evolution is measured for different exchange rates, using the time-dependent block entropy method. Empirical results suggest that financial crises are associated with significant increase of exchange rate entropy, reflecting instability in FX market dynamics. In accordance with phenomenological expectations, it is found that FX markets with large liquidity and large trading volume are more inert - they recover quicker from a crisis than markets with small liquidity and small trading volume. Moreover, our numerical analysis shows that periods of economic uncertainty are preceded by periods of low entropy values, which may serve as a tool for anticipating the onset of financial crises.

  8. Networked Social Reproduction: Crises in the Integrated Circuit

    Directory of Open Access Journals (Sweden)

    Elise Danielle Thorburn

    2016-07-01

    Full Text Available This paper argues that the means of communication are sites for, and aspects of, social reproduction. In contemporary capitalism, motivated as it is by new, networked digital technologies, social reproduction is increasingly virtualised through the means of communication. Although recent political struggles have demonstrated how networked technologies can liberate social reproduction from the profit motive and from commodifying impulses, the tendency is to invoke and accelerate socially reproductive crises—crises in the capacity to reproduce ourselves both daily and intergenerationally. These crises have psychic and corporeal impacts, and intensify Tronti’s “social factory” thesis of capital’s technical composition. In order to develop modes and means of liberatory communication in the integrated circuit it is necessary to untangle and chart both the pathways and outcomes of the crises networked social reproduction invokes.

    This paper considers the effect of systemic financial crises on aggregate consumption. Using a sample of 23 countries over 32 years, we find that consumption growth seems lower during banking crises, crises following credit booms and crises following house price booms. Moreover, the response to income growth seems to change, which may be due to credit constraints. In the long run, consumption appears to be linked to income, housing and other financial wealth.

  1. Are We Entering an Era of Concatenated Global Crises?

    Directory of Open Access Journals (Sweden)

    2011-06-01

    Full Text Available An increase in the frequency and intensity of environmental crises associated with accelerating human-induced global change is of substantial concern to policy makers. The potential impacts, especially on the poor, are exacerbated in an increasingly connected world that enables the emergence of crises that are coupled in time and space. We discuss two factors that can interact to contribute to such an increased concatenation of crises: (1 the increasing strength of global vs. local drivers of change, so that changes become increasingly synchronized; and (2 unprecedented potential for the propagation of crises, and an enhanced risk of management interventions in one region becoming drivers elsewhere, because of increased connectivity. We discuss the oil-food-financial crisis of 2007 to 2008 as an example of a concatenated crisis with origin and ultimate impacts in far removed parts of the globe. The potential for a future of concatenated shocks requires adaptations in science and governance including (a an increased tolerance of uncertainty and surprise, (b strengthening capacity for early detection and response to shocks, and (c flexibility in response to enable adaptation and learning.

    2018-02-01

    Extensive works have reported that a financial crisis can induce significant changes to topological structure of a stock network constructed with cross-correlations between stocks. But there are still some problems to be answered, such as what is the relationship between different crises in history and how to classify them? In the present work, we propose a new network-based solution to extract and display the relationships between the crises. The Dow Jones stock market is investigated as a typical example. The cross-correlation matrix between stocks is used to measure the state of stock market, called state matrix. All the states cluster into six sub-categories. A state network is constructed further to display the relationships between all the states, which contains a total of nine communities. It is found that three crises C , D and E (refer to the Lehman's bankruptcy in 2008, the Euro-zone and International Monetary Fund decide the first bailout for Greece in 2010, and the European sovereign debt crisis in 2011, respectively) belong to a specific sub-category and cluster in a single community. The mid-stage of C is closely linked with E, while the other stages with D. The other two crises A and B (refer to the financial crisis in Asia in 1997, and the burst of "dot-com bubble" in 2002, respectively) belong to another sub-category and gather in a corner of another single community. A and B are linked directly with C and D by two edges. By this way, we give a clear picture of the relationships between the crises.

    BACKGROUND Myonecrosis is one of the more poorly studied, painful manifestations of sickle cell crisis. Medical literature is sparse detailing the manifestations and management of such symptoms. In myonecrosis, red cells containing sickle hemoglobin become rigid, resulting in reduced blood flow and myonecrosis. CASE REPORT We present a case study of a patient in sickle cell crisis with an episode of acute pain and swelling to the intrinsic muscles of the foot as a prominent feature of the crises. Although muscle biopsy is considered the gold standard for the diagnosis of myositis or myonecrosis, a low intensity signal on T1 and high intensity signal on T2 at the affected muscle belly can be as conclusive as imaging studies. In an actively sickling patient any invasive intervention should be avoided as it can result in ischemic necrosis of the tissues, due to interruption of capillary flow in end-arteries. CONCLUSIONS Early recognition is critical in sickle cell disease management, allowing for prompt and aggressive fluid resuscitation which remains a cornerstone in the management of most sickle cell vaso-occlusive crises. In this instance, off loading the extremity and early fluid resuscitation resolved the pain and swelling and prevented myonecrosis.

    Full Text Available The 2008 economic crisis challenged accounting, either demanding recognition and measurement criteria well adjusted to this scenario or even questioning its ability to inform appropriately entities’ financial situation before the crisis occurred. So, our purpose was to verify if during economic crises listed companies in the Brazilian capital market tended to adopt earnings management (EM practices. Our sample consisted in 3,772 firm-years observations, in 13 years – 1997 to 2009. We developed regression models considering discretionary accruals as EM proxy (dependent variable, crisis as a macroeconomic factor (dummy variable of interest, ROA, market-to-book, size, leverage, foreign direct investment (FDI and sector as control variables. Different for previous EM studies two approaches were used in data panel regression models and multiple crises were observed simultaneously. Statistics tests revealed a significant relation between economic crisis and EM practices concerning listed companies in Brazil in both approaches used.

  16. Resilience of natural gas networks during conflicts, crises and disruptions.

    Directory of Open Access Journals (Sweden)

    Rui Carvalho

    Full Text Available Human conflict, geopolitical crises, terrorist attacks, and natural disasters can turn large parts of energy distribution networks offline. Europe's current gas supply network is largely dependent on deliveries from Russia and North Africa, creating vulnerabilities to social and political instabilities. During crises, less delivery may mean greater congestion, as the pipeline network is used in ways it has not been designed for. Given the importance of the security of natural gas supply, we develop a model to handle network congestion on various geographical scales. We offer a resilient response strategy to energy shortages and quantify its effectiveness for a variety of relevant scenarios. In essence, Europe's gas supply can be made robust even to major supply disruptions, if a fair distribution strategy is applied.

The main attention is paid to the large-scale crisis of 1899–1902 at the new industrial region in Eastern Ukraine where numerous steel and mining companies based on massive foreign investment (mainly Belgian and French were created shortly. The general boom of new joint-stock companies and insufficient provision of these companies by state orders were the main reason of the crisis which was the reflection of the international industrial and financial crisis of those years. The author also researches the crisis of 1908–1910 in the Ukrainian sugar industry.

    Full Text Available Many studies have been carried out to investigate the impact of recent European financial crises on the performance of financial instruments in other regions. Nevertheless, there have been insufficient studies explaining such impact on Islamic financial instrument. In particular, whether Greece Financial crises have affected performance of Sukuk traded in Gulf Markets needs to be answered. This study is aimed at empirically investigating the causality of credit and liquidity risk on Sukuk Markets in Gulf economies in the period of Greece Financial Crises. We analyzed the Sukuk data by employing Granger casuality test, with all the associated vector autoregression model procedures. Our findings show that Bahrain sukuk market is cointegrated with those of Qatar and UAE in the full period observation. Meanwhile, during the crisis, Qatar Sukuk market is cointegrated with those of UAE Bahrain. We also find that Bahrain Sukuk triggers market shock in both Qatar and UAE Sukuk markets. Bahrain consistently causes changes in price and spread of UAE Sukuk, both in the context of the full period and the during-crisis period.DOI: 10.15408/aiq.v9i1.3733

  6. Crises in clinical care: an approach to management.

    2005-06-01

    A "crisis" in health care is "the point in the course of a disease at which a decisive change occurs, leading either to recovery or to death". The daunting challenges faced by clinicians when confronted with a crisis are illustrated by a tragic case in which a teenage boy died after a minor surgical procedure. Crises are challenging for reasons which include: presentation with non-specific signs or symptoms, interaction of complex factors, progressive evolution, new situations, "revenge effects", inadequate assistance, and time constraints. In crises, clinicians often experience anxiety- and overload-induced performance degradation, tend to use "frequency gambling", run out of "rules" and have to work from first principles, and are prone to "confirmation bias". The effective management of crises requires formal training, usually simulator-based, and ideally in the inter-professional groups who will need to function as a team. "COVER ABCD-A SWIFT CHECK" is a pre-compiled algorithm which can be applied quickly and effectively to facilitate a systematic and effective response to the wide range of potentially lethal problems which may occur suddenly in anaesthesia. A set of 25 articles describing additional pre-compiled responses collated into a manual for the management of any crisis under anaesthesia has been published electronically as companion papers to this article. This approach to crisis management should be applied to other areas of clinical medicine as well as anaesthesia.

    2016-09-01

    The present study is a systematic review of empirical literature from the last 35 years on families' responses to economic distress in the context of macroeconomic crises. Thirty-nine studies published between 1983 and 2015 in 12 countries were identified, resulting in 3 main findings. First, economic distress was associated with negative changes in family dynamics, specifically couple relationships and parenting. Second, protective factors were found to buffer the adverse effects of economic distress on family and individual outcomes. Third, the results suggest that individual responses to macroeconomic crises may be moderated by sex. Implications for future research encompass using validated assessment instruments, including participants beyond 2-parent families with adolescent children and conducting both longitudinal and qualitative studies that focus on the processes and meanings of adaptation within this risk context. Conclusions highlighted the need to assist families dealing with macroeconomic crises' demands, encouraging the development and validation of macrosystemic intervention programs.

As with adults, pediatric patients with HTN can present with hypertensive crises include hypertensive urgency and hypertensive emergencies. However, pediatric blood pressure problems have a greater chance of being from secondary causes of HTN, as opposed to primary HTN, than in adults. Thorough evaluation of a child with a hypertensive emergency includes accurate blood pressure readings, complete and focused symptom history, and appropriate past medical, surgical, and family history. Physical exam should include height, weight, four-limb blood pressures, a general overall examination and especially detailed cardiovascular and neurological examinations, including fundoscopic examination. Initial work-up should typically include electrocardiography, chest X-ray, serum chemistries, complete blood count, and urinalysis. Initial management of hypertensive emergencies generally includes the use of intravenous or oral antihypertensive medications, as well as appropriate, typically outpatient, follow-up. Emergency department goals for hypertensive crises are to (1 safely lower blood pressure, and (2 treat/minimize acute end organ damage, while (3 identifying underlying etiology. Intravenous antihypertensive medications are the treatment modality of choice for hypertensive emergencies with the goal of reducing systolic blood pressure by 25% of the original value over an 8

    2008-01-01

    Organizational crises are rare, yet they fundamentally influence the evolution of organizations. An aspect of crises deserving more attention is the interaction of organizations and their stakeholders during a crisis from a legitimation perspective. This paper presents a simulation model mapping causal relationships behind this interaction. Results suggest that the nature and timing of organizational response to crises has considerable effect on the success and duration of attempts of regaini...

    Full Text Available Este artigo apresenta criticamente diferentes interpretações da crise atual. Orientaram a seleção das várias contribuições a representatividade das teorias marxistas clássicas de crise e a importância das novas abordagens correspondentes aos novos fenômenos em desenvolvimento no capitalismo atual. O exame crítico dessas contribuições revela uma linha divisória entre aqueles que concebem a crise como tendo sido causada pelo afluxo dos lucros da produção para as finanças (Husson e Foster /Magdoff e aqueles para os quais o aumento do crédito de consumo foi resultado de uma reestruturação dos fluxos de crédito das empresas, cada vez mais autônomas no mercado de dinheiro, às famílias assalariadas, cada vez mais dependentes do financiamento bancário. Essa linha divisória reflete a importância que o primeiro grupo adjudica à diminuição do ritmo de crescimento vis-à-vis os teóricos da School of Oriental and African Studies. A análise revela também que a atrofia da economia política leva a um abandono precoce da teoria bancária e financeira de Marx em favor dos instrumentos teóricos pós-keynesianos imediatamente disponíveis para o uso.This article is a critical survey of different interpretations of the 2007-2008 financial crises. They were chosen either because they represented classical Marxian views on crisis, such as the underconsumption or over-accumulation theories, or else because they were newly developed interpretations based on recent newly economic developments, as it is the case of the financial expropriation theory. The analysis reveals three main points of view. The first is that the cause of crisis is the stagnation of the economy and the ensuing transfer of profits from production to finance, process that caused the housing-financial bubble (Husson and Foster/Magdoff. The second view argues that it was the structural change in financial markets which led banks to increasingly rely on consumer credit

  12. Do Economic Reforms Alleviate Subjective Well-Being Losses of Economic Crises?

    Major economic crises tend to be followed by crises in subjective well-being. Following the financial and debt crises, politicians and social scientists have engaged in heated discussions of ways to alleviate such losses. In particular, should governments intervene more or less? This paper explores...... whether liberalizing economic institutions, a type of reform favoured by some economists, is likely to alleviate such loses. Estimating the effects of crises across European states 1975–2011 suggest that countries with relatively easy market regulations suffered smaller well-being losses....

    2011-06-01

    Full Text Available Ethics and trust can avoid crises, just as, as recent events have clearly proved, the reverse is true. The paper is simply constructed: Section 1 provides a historical analysis; Section 2 deals with today‟s situation, drawing similarities and differences and the possible outcomes thereby arising; the final section concludes. Historical data are difficult to come by for most countries, especially when they should also be comparable across time. In general, and for this reason, US data have been used: however, the situation in other countries was little different, as will be shown, so that the data may be considered to be representative.

    Psychological disorders which become manifest as adolescent crises must be seen as complex phenomena and treated thoroughly: besides the genetic, biographic and psychosocial background of the youthful individual the cultural and economic aspects play an important role. Nevertheless we must admit that associated causal explanations, e.g. for accelerated or late development are lacking. Focal points for the subsequent symptom complexes of sexual behavior in puberty are: psychosexual prematurity or retardation, masturbation, homosexual relations, pubertal asceticism and premature and frequently changing sexual relations.

    Erikson (1959) proposed a theoretical basis for healthy psychosocial development. His theory posits eight critical conflict situations throughout one's lifetime, each of which can result in a favorable or unfavorable resolution. Autobiographies, memoirs, interviews, personal diaries, and oral histories of 97 international astronauts were content analyzed to assess reported resolutions of Erikson's psychosocial crises, regardless of chronological sequence. We made comparisons across flight phases (before, during, and after), gender, nationality of home space agency, and flight duration. Astronauts reported more favorable than unfavorable outcomes across flight phases and demographic variables. Differences across demographic variables and flight phases, as well as the changes as a result of the flight are discussed.

  4. Constituição, realidade e crise

    Wilson Antônio Steinmetz

    2016-12-01

    ção enquanto locus epistêmico de análise e reflexão sobre as constituições. O que muda é a descrição ou a interpretação da relação entre Constituição e realidade que cada uma das inúmeras teorias da Constituição propõe e a ênfase, descritiva ou valorativa, que se atribui aos polos da relação. Na atual quadra da história do Brasil, retomar a pesquisa e a reflexão rigorosas sobre a dialética Constituição-realidade é, se não uma imposição, muito recomendável à comunidade científica do direito, especialmente àqueles que investigam o direito como fenômeno normativo e suas projeções sobre as relações políticas e sociais. Nosso País vive aquela que talvez seja a maior crise após a redemocratização. À crise política somam-se uma crise econômica e uma crise financeira do Estado, nos três níveis da Federação. A crise política por si mesma não seria atemorizante ou ameaçadora. Desde a redemocratização em meados dos anos 1980, atravessamos crises políticas sem rupturas institucionais ou constitucionais. No pós-1988, a Constituição tem se mostrado adequada e, ao mesmo tempo, resistente às crises políticas sazonais. No entanto, há fundados motivos para supormos que a atual crise – que possui uma dimensão política, uma dimensão econômica e uma dimensão financeira – desafia e continuará desafiando a engenharia institucional e organizacional desenhada pela Constituição de 1988. Primeiro, as dimensões da crise formam uma unidade, estão profundamente imbricadas. Passados dois anos, constata-se que a solução da crise geral depende de uma solução articulada ou encadeada das três dimensões. Segundo, o País necessita de uma ampla reforma política para a qual os partidos, os grupos e as facções políticas parecem ter disposição nenhuma para convergir. Terceiro, a crise sinaliza que o Estado brasileiro, em todas as suas esferas, já não tem condições de, simultaneamente, cumprir todas as tarefas que a Constitui

  5. Propagation of crises in the virtual water trade network

    Science.gov (United States)

    Tamea, Stefania; Laio, Francesco; Ridolfi, Luca

    2015-04-01

    The international trade of agricultural goods is associated to the displacement of the water used to produce such goods and embedded in trade as a factor of production. Water virtually exchanged from producing to consuming countries, named virtual water, defines flows across an international network of 'virtual water trade' which enable the assessment of environmental forcings and implications of trade, such as global water savings or country dependencies on foreign water resources. Given the recent expansion of commodity (and virtual water) trade, in both displaced volumes and network structure, concerns have been raised about the exposure to crises of individuals and societies. In fact, if one country had to markedly decrease its export following a socio-economical or environmental crisis, such as a war or a drought, many -if not all- countries would be affected due to a cascade effect within the trade network. The present contribution proposes a mechanistic model describing the propagation of a local crisis into the virtual water trade network, accounting for the network structure and the virtual water balance of all countries. The model, built on data-based assumptions, is tested on the real case study of the Argentinean crisis in 2008-09, when the internal agricultural production (measured as virtual water volume) decreased by 26% and the virtual water export of Argentina dropped accordingly. Crisis propagation and effects on the virtual water trade are correctly captured, showing the way forward to investigations of crises impact and country vulnerability based on the results of the model proposed.

  6. Early Warning Models for Systemic Banking Crises in Montenegro

    Directory of Open Access Journals (Sweden)

    Željka Asanović

    2013-06-01

    Full Text Available The purpose of this research is to create an adequate early warning model for systemic banking crises in Montenegro. The probability of banking crisis occurrence is calculated using discrete dependent variable models, more precisely, estimating logit regression. Afterwards, seven simple logit regressions that individually have two explanatory variables are estimated. Adequate weights have been assigned to all seven regressions using the technique of Bayesian model averaging. The advantage of this technique is that it takes into account the model uncertainty by considering various combinations of models in order to minimize the author’s subjective judgment when determining reliable early warning indicators. The results of Bayesian model averaging largely coincide with the results of a previously estimated dynamic logit model. Indicators of credit expansion, thanks to their performances, have a dominant role in early warning models for systemic banking crises in Montenegro. The results have also shown that the Montenegrin banking system is significantly exposed to trends on the global level.

A análise combinada dos dados disponíveis no CAGED e na RAIS evidencia o encolhimento do mercado formal de trabalho em 2015, e de forma mais expressiva nos municípios de maior porte demográfico. Entretanto, a despeito da intensificação da crise econômica a partir de 2013, no período 2013-2015, centenas de outros municípios tradicionalmente mais frágeis economicamente não vivenciaram a severidade do impacto da crise no emprego, muitos deles localizados nas áreas setentrionais da região, as que se assemelham com a região Nordeste do Brasil, espaços nos quais foram maiores os impactos das ações das políticas sociais dos últimos governos.

    Full Text Available A crise financeira global de 2008 foi conseqüência do processo de financeirização, a criação maciça de riqueza financeira fictícia iniciada da década de 1980, e da hegemonia de uma ideologia reacionária, o neoliberalismo, baseada em mercados auto-regulados e eficientes. Dessa crise emergirá um novo capitalismo, embora sua natureza seja de difícil previsão. Não será financeirizado, mas serão retomadas as tendências presentes nos trinta anos dourados em direção ao capitalismo global e baseado no conhecimento, além da tendência de expansão da democracia, tornando-a mais social e participativa.The 2008 global financial crisis was a consequence of the processes of financialization, the massive creation of fictitious financial wealth which began in the 1980's, and of the hegemony of a reactionary ideology, neoliberalism, based on the belief of the self-regulating capacity and efficiency of markets. From this crisis a new capitalism will emerge, althought its chacarteristics are hard to foresee. It will not be financial, but the tendencies of the 30 "golden years" toward global and knowledge-based capitalism, and the tendency of expansion of democracy will be among them.

    Full Text Available Resumo Este artigo mostra que a crise de 2014/2017 é fruto de uma combinação de choques de oferta e demanda resultado de erros de política econômica. Esses choques produziram uma redução da capacidade de crescimento da economia brasileira e risco de insolvência das finanças públicas. A solução da crise fiscal, através da PEC do teto dos gastos, fará que o país retome o crescimento econômico a partir de 2017, utilizando a capacidade ociosa da economia. No entanto, a taxa de crescimento do produto potencial não recuperará o ritmo anterior devido aos efeitos duradouros das políticas da Nova Matriz Econômica (NME que reduziram o produto potencial nacional. Recomenda-se, portanto, a adoção de políticas que induzam uma recuperação da produtividade da economia brasileira.

  10. Improving communication during volcanic crises on small, vulnerable islands

    2009-05-01

    Increased exposure to volcanic hazard, particularly at vulnerable small islands, is driving an urgent and growing need for improved communication between monitoring scientists, emergency managers and the media, in advance of and during volcanic crises. Information gathering exercises undertaken on volcanic islands (Guadeloupe, St. Vincent and Montserrat) in the Lesser Antilles (eastern Caribbean), which have recently experienced - or are currently experiencing - volcanic action, have provided the basis for the compilation and publication of a handbook on Communication During Volcanic Emergencies, aimed at the principal stakeholder groups. The findings of the on-island surveys point up the critical importance of (1) bringing together monitoring scientists, emergency managers, and representatives of the media, well in advance of a volcanic crisis, and (2), ensuring that procedures and protocols are in place that will allow, as far as possible, effective and seamless cooperation and coordination when and if a crisis situation develops. Communication During Volcanic Emergencies is designed to promote and encourage both of these priorities through providing the first source-book addressing working relationships and inter-linkages between the stakeholder groups, and providing examples of good and bad practice. While targeting the volcanic islands of the eastern Caribbean, the source-book and its content are largely generic, and the advice and guidelines contained therein have equal validity in respect of improving communication before and during crises at any volcano, and have application to the communication issue in respect of a range of other geophysical hazards.

    Aims This paper is a report of a study of health-related quality of life and post-traumatic stress disorder symptoms in patients attending an Accident and Emergency department because of psychosocial crises. Background Psychosocial crises are commonplace globally, but there is little knowledge about patients attending Accident and Emergency departments because of psychosocial crises. Methods Data were collected at an Accident and Emergency department in Norway from September 2008 to June 2009. A total of 99 adults participated in the baseline study and 41 of these participated at 2 months follow-up. The Short Form-36 Health Survey and the Post Traumatic Symptom Scale were used to obtain data. Findings Participants reported significantly lower scores in all health-related quality of life domains at baseline compared with the general Norwegian population. The mental health score was two standard deviations below the norm. Health-related quality of life scores were improved and post-traumatic stress disorder symptoms were reduced after 2 months. High levels of post-traumatic stress disorder symptoms were reported by 78% of the participants at baseline and 59% at follow-up. Participants with high levels of post-traumatic stress disorder symptoms at follow-up also reported low health-related quality of life scores. Conclusion This study suggests a need for an acute psychosocial intervention and an opportunity to receive follow-up support at Accident and Emergency departments. PMID:21740459

    The growing dependency of Europe as a whole on energy imports and anticipated further increases in energy prices reinforce the concerns about meeting the energy demand in the future. The objective of the Study is to identify the threats leading to potential energy crises and suggest solutions for facing, in an appropriate way, the related key challenges. In addition, the Study intends to develop a number of indicators effective enough to assess the level of different types of vulnerability, as well the overall vulnerability of a country or region, including threats to physical disruption, higher energy prices etc. The use of vulnerability indicators is highly recommended for all WEC-European countries, as well as to policy makers and market players.

  18. Economic Crises and the Complexity of Animal Spirits Modeling

    Directory of Open Access Journals (Sweden)

    Grigore PIROŞCĂ

    2011-02-01

    Full Text Available The rationale of this research goes into the origins of the economic crises from a different way of economic thinking, hence the professional interest on bringing again into the light the concept of animal spirits, used for the first time from classic liberals like David Hume, developed by doctrine founder John Maynard Keynes, and captured as groundbreaking economic crisis hypothesis in Nobel Prize laureates’ books like George Akerlof. A familiar account of the last financial crisis underlines the collapse of confidence and evaporation of trust which leaded to failure of corporate governance and easy money policy. Nor were these problems of recent origin; they were rooted in deep structural changes in the economy that date back many years. Financial innovations overheated the world economy and gained steam because of irrational exuberance over a risk free better future. Considering the evidence analyzed in this paper work, this approach of economic crisis through animal spirits puts forward new highlights of economic thought.

  19. The Cyclical Behaviour of Global Economic Crises and Their Strenght

    Directory of Open Access Journals (Sweden)

    Simona Moagăr-Poladian

    2010-04-01

    Full Text Available In the last 40 years, the world crises have become more and more intensely and serious. The decoupling phenomenon between the financial flows and commodities flows has shown the political factors involvement in international monetary flows, reflected first of all by the increasing military expenses in the contemporary world economy. The petroleum shocks from ‘74-‘75 years had generated monetary flows of petrodollars that accentuated the international financial assumptions. The financial movements have overlapped to a less currency utilisation in the material trade owing to the fact that the consistent dropping of the world trade stimulated trade by swap. The unbalanced distribution of the international financial liquidities, the chronical disequilibrium of current account balance, approval of high rate of exchange rate volatility and multiple currency approvals explain somewhat the differing economic growth on the world level.

    The ability to reliably predict critical transitions in dynamical systems is a long-standing goal of diverse scientific communities. Previous work focused on early warning signals related to local bifurcations (critical slowing down) and nonbifurcation-type transitions. We extend this toolbox and report on a characteristic scaling behavior (critical attractor growth) which is indicative of an impending global bifurcation, an interior crisis in excitable systems. We demonstrate our early warning signal in a conceptual climate model as well as in a model of coupled neurons known to exhibit extreme events. We observed critical attractor growth prior to interior crises of chaotic as well as strange-nonchaotic attractors. These observations promise to extend the classes of transitions that can be predicted via early warning signals.

    2004-01-01

    Full Text Available The remarkable properties of shape memory alloys have been motivating the interest in applications in different areas varying from biomedical to aerospace hardware. The dynamical response of systems composed by shape memory actuators presents nonlinear characteristics and a very rich behavior, showing periodic, quasi-periodic and chaotic responses. This contribution analyses some aspects related to bifurcation phenomenon in a shape memory oscillator where the restitution force is described by a polynomial constitutive model. The term bifurcation is used to describe qualitative changes that occur in the orbit structure of a system, as a consequence of parameter changes, being related to chaos. Numerical simulations show that the response of the shape memory oscillator presents period doubling cascades, direct and reverse, and crises.

  3. Coping with Financial Crises: Latin American Answers to European Questions

    Full Text Available Europe faces challenges reminiscent of Latin American financial crises, namely unsustainable sovereign spreads, banking system distress, sudden stops in capital flows and growth rate collapse. The failure of recent liquidity support to normalize the situation suggests the need to refocus the policy debate on fundamentals: structural reform for growth and, where needed, restructuring to resolve banking crises and the debt overhang.  Latin America’s experience yields relevant policy lessons for Europe on all these fronts, tempered only by the slight exception that sharp real devaluation, which was key to spearheading recovery in Latin America, is unfeasible in the eurozone. Struggling eurozone countries are caught between a rock and a hard place, as the currency union imposes strict policy constraints while the reintroduction of national currencies under conditions of crisis would be catastrophic. Nevertheless, contemporary Europe stands a better chance of recovery because, in contrast with the Latin America experience, the European Union possesses greater avenues for international cooperation. With respect to financial support, a resourceful European Central Bank able to avoid chaotic adjustment by brute force is a decisive advantage of Europe relative to Latin America, which only had access to the weaker and less reliable IMF. Arguably, the limited nature of external support strongly contributed to the depth of Latin America’s great collapses. European cooperation can explore and exhaust alternatives to a euro exit to the benefit of all union members and, if dissolution becomes unavoidable, ensure amicable support to ease the transition. The path to success remains uncharted, however, and implementation of the necessary regional mechanisms will require innovation and political will. If the available means of cooperation are not used effectively, crisis countries in Europe may fare worse than those in Latin America.

  4. Nouvelles analyses des crises alimentaires en Afrique de l'Ouest

    Full Text Available New analyses of food crises in West Africa. The issue of crisis is a central element of debate and a strategic challenge for all stakeholders in West Africa. Food and nutrition crises are recurrent in the region, with a level of intensity and high variability constituting renewed challenges. The definition, delimitation and management of these crises are provided by an established and structured professional field, which favors intervention. Different conceptual and contextual approaches can be mobilized to account for the diversity and complexity of food and nutrition crises. Some more descriptive approaches list the causes and manifestations of these crises, while others insist on the fact that they are created, and identify their dynamic as being linked to interactions between various phenomena. To date, most of the various institutional actors involved in addressing food and nutrition crises, both at national and international levels, have favored the gradual improvement of expert systems providing technical short-term responses. In parallel, this has led to a harmonization of these frameworks of thought, which has been detrimental to the consideration of the diversity of questions and the integration of non-institutional actors. These are the boundaries and limitations that this article aims to question, in order to reinvoke the political dimension of the management of food crises (and their eventual resolution.

    The aim of the present study was to test the effects of hydroxyurea (HU) therapy on clinical, hematological and hemorheological parameters in adult patients with sickle cell anemia (SCA). Hematological and hemorheological parameters were measured in 28 SCA patients before HU therapy (i.e., baseline) and at 6, 12 and 24 months of treatment. RBC deformability was determined by ektacytometry at 30 Pa. RBC aggregation properties were investigated by light-backscatter method. Blood viscosity was measured at 225 s-1 by a cone-plate viscometer. The rates of vaso-occlusive crises and acute chest syndrome were lower at 1 and 2 years of HU therapy compared to baseline. The proportion of patients with leg ulcers tended to decrease after 2 years of treatment. Hemoglobin oxygen saturation improved with HU therapy. HU therapy induced a decrease of platelet and white blood cell counts and a rise in fetal hemoglobin level and mean cell volume. While hemoglobin concentrations increased under HU, blood viscosity remained unchanged all along the study. RBC deformability increased over baseline values at 6 months of HU therapy and continued to rise until the end of the follow-up period. In conclusion, the improvement in RBC deformability probably compensates the increase of hemoglobin on blood viscosity and participates to the improvement of the clinical status of patients.

    Full Text Available NM Wiles, J HowardDepartment of Haematology, St Thomas’ Hospital, Westminster, Bridge Road, London, SE1 7EH, UKAbstract: Sickle cell disease (SCD is a genetically inherited condition caused by a point mutation in the beta globin gene. This results in the production of the abnormal hemoglobin, sickle hemoglobin (HbS. Hydroxycarbamide, is an antimetabolite/cytotoxic which works by inhibiting ribonucleotide reductase, blocking the synthesis of DNA and arresting cells in the S phase. In sickle cell anemia, it promotes fetal hemoglobin (HbF synthesis, improves red cell hydration, decreases neutrophil and platelet count, modifies red cell endothelial cell interactions and acts as a nitric oxide donor. Trials have shown the clinical benefit of hydroxycarbamide in a subpopulation of adult patients with SCD, with a 44% reduction in the median annual rate of painful crises, a decrease in the incidence of acute chest syndrome and an estimated 40% reduction in overall mortality over a 9-year observational period. Its use in pediatrics has also been well established; trials have shown it is well tolerated and does not impair growth or development. In addition it decreases the number and duration of hospital attendences. A number of emerging uses of hydroxycarbamide currently are being investigated, such as stroke prevention.Keywords: sickle cell anemia, hydroxycarbamide, hydroxyurea, maximum tolerated dose, vaso-occlusive crisis

    The search for effective therapeutic interventions for sickle cell disease (SCD) has been an ongoing endeavor for over 50 years. During this period, only hydroxyurea (HU), which received US FDA approval in February 1998, was identified as an effective therapeutic agent in preventing or ameliorating the frequency of vaso-occlusive crises, acute chest syndrome and the need for blood transfusion. Approximately 25% of patients with sickle cell anemia (SCA), however, do not respond to HU and some patients experiencing serious side effects of this chemotherapeutic agent. Nevertheless, the success of HU opened the sluice gates to identify other effective drug therapies. The objective of this review is to describe the emerging drug therapies for SCA. In this review, we describe the pathophysiology of SCD and provide an in-depth analysis of the current and new pharmacologic therapies in the field. Literature searches involved multiple databases including Medline In-Process & Other Non-Indexed Citations, MEDLINE, Embase, Cochrane Database of Systematic Reviews, and Scopus. SCA is a heterogeneous disease that has caused tremendous global morbidity and early mortality. More effective, individualized and inexpensive therapies are needed. New therapies targeting multiple pathways in its complex pathophysiology are under investigation.

    In an attempt to test Kandell's proposition that internet dependents used the internet as a coping mechanism against underlying psychological issues, this study investigated the extent to which the fifth and sixth Eriksonian crises (identity, intimacy), were related to internet dependence (online chatting, gaming) among college students. Students spending more than 10 hours per week on chatting/gaming were classified as dependents. On the basis of a national sample of freshmen in Taiwan, this study found that the dependents scored significantly lower on most of the measures that reflected the successful resolution of the crises, and higher on the measures that reflected unsuccessful resolution of the crises. Kandell's proposition was supported.

Esse ensaísmo produziu alguns textos que se transformaram, por meio da crítica, em clássicos da reflexão sobre o país - tais como Radiografía de la pampa, de Ezequiel Martínez Estrada, e Historia de una pasión argentina, de Eduardo Mallea -, e que se gestaram sobre a base de uma crise política - sua primeira exteriorização foi o golpe de Estado de 1930 - e de uma desordem mais ampla dos pontos intelectuais de referência, em consequência da falência do positivismo entre as elites culturais. O dissabor provocado pelo contexto político nacional se mesclou ao mal-estar oriundo do pensamento europeu sobre a crise - crise do espírito, da ordem liberal e do capitalismo -, e esse amálgama alimentou um estado de descontentamento intelectual que ganhou forma na reflexão ensaística. De modo cada vez mais amplo, esse gênero dá início a uma rigorosa revisão da Argentina liberal, no âmbito de cuja produção destacam-se os referidos ensaios de Martínez Estrada e de Mallea, que serão analisados na parte final do presente estudo.This study analyzes a sector of Argentine thought from the 1930s, represented in the essays on the national 'soul' or character.

    Full Text Available Social and cultural anthropologists have made a unique, relevant and anti-normative contribution to the study of crises. By means of ethnographic fieldwork in specific settings, anthropologists have provided significant information on how social groups try to cope with critical situations in everyday life resorting to different strategies, forms of cooperation or political action. Simultaneously, anthropology has brought to light the role played by cognitive schemata and symbolic resources in making sense of crisis situations, turning them intelligible and developing possible resolutions. Anthropology has carried out important studies on how people experience time, give meaning to and produce plausible images of the future in crisis situations, when time freezes. The main theoretical contributions to the study of crises will be discussed, together with a number of empirical studies among which special attention will be paid to those carried out in Latin America, including my own research on the experiences and responses of the middle class during the 2001 Argentine crisis.   Resumen Los antropólogos sociales y culturales han hecho una contribución única, relevante y anti-normativa a los estudios de crisis.

Uma grande variedade de instituições financeiras frouxamente reguladas e displicentemente supervisionadas passou a constituir a contraparte da transferência de riscos de crédito do sistema bancário e a carregar riscos crescentes. O artigo procura discutir a interação dessas instituições financeiras, incluindo algumas características do principal palco dessa interação - os mercados de balcão - e a utilização de determinadas inovações financeiras que amplificaram a crise. Dada a complexidade e opacidade dessas instituições e mercados, busca ainda explicitar a necessidade de aperfeiçoamentos na sua regulação e supervisão.The financial crisis triggered by increasing default rate, real estate devaluation and financial asset depreciation combined with U.S. subprime mortgages brought about the debate over the framework of the U.S. and international financial systems, their potential systemic risks, and their regulatory and supervisory mechanisms. A great variety of financial institutions which were poorly regulated and badly supervised changed into the counterpart of the credit risk transfer from the banking system and started to hold increasing risks. This paper deals with the interaction of these financial institutions, including a description of some features of the major stage in this process - the so-called over-the-counter (OTC market - and the use of financial innovations which amplified the crisis. It also aims to clarify the need for improvements in terms of regulation and supervision considering the complexity and opacity of these institutions and markets.

  20. Preventing food crises using a food policy approach.

    Science.gov (United States)

    Timmer, C Peter

    2010-01-01

    A food crisis occurs when rates of hunger and malnutrition rise sharply at local, national, or global levels. This definition distinguishes a food crisis from chronic hunger, although food crises are far more likely among populations already suffering from prolonged hunger and malnutrition. A food crisis is usually set off by a shock to either supply or demand for food and often involves a sudden spike in food prices. It is important to remember that in a market economy, food prices measure the scarcity of food, not its value in any nutritional sense. Except in rare circumstances, the straightforward way to prevent a food crisis is to have rapidly rising labor productivity through economic growth and keep food prices stable while maintaining access by the poor. The formula is easier to state than to implement, especially on a global scale, but it is good to have both the objective, reducing short-run spikes in hunger, and the deep mechanisms, pro-poor economic growth and stable food prices, clearly in mind. A coherent food policy seeks to use these mechanisms, and others, to achieve a sustained reduction in chronic hunger over the long run while preventing spikes in hunger in the short run.

    The importance of animal health crises has considerably increased over the last few years. When a crisis occurs, farmers can receive financial support through various public, private and mixed compensation schemes. Economic losses resulting from diseases may be direct and indirect. If a disease is covered by European Union regulations then countries have a legal obligation to partly compensate farmers for direct losses, either directly through the national budget, or through a specific fund. The European Veterinary Fund also co-finances these losses. Only a few countries provide compensation for indirect losses. The private insurance sector also provides protection against some direct and indirect losses but the risks covered are variable. To encourage farmers to subscribe to this kind of insurance, some public authorities provide subsidies to help pay the premium. Insurance companies do not generally cover the risks linked to contagious diseases, but some companies do extend cover to include this type of risk. Several alternatives, such as mutual funds, are available to improve risk coverage. There is a lack of harmonisation among the various compensation schemes of different countries. Public authorities cannot provide full compensation, but mutual funds and private insurance companies are alternatives that should be further investigated and their use should be extended to other countries. A classification of diseases would harmonise the situation at the European level.

    1995-01-01

    On the occasion of a rather incidental visit in the sanatorium "Berghof" at Davos, Hans Castorp, the--as to his primary personality--asthenic and low-profile protagonist of the "Zauberberg" is gradually getting caught up in the maelstrom of the there prevailing timelessness and irresponsibility, this being interrupted solely by two tapering to crisis episodes: his amouressness to Mme. Chauchat as an erotic crisis and by the visionary daydream during a snowstorm about the abilities of men as a cognitive, mental crisis. Both events are triggered by a pathoid irritability, following the maxim of Th. Mann that illness, decay and death as borderline experiences may be the presupposition for cognition and reversal. Both crises end without consequences--the "Zauberberg" is the negation of the novel of education and development in the narrower sense. The unsuccessfulness and undecidedness of Hans Castorp's existence culminate in the open end of the novel, regarding his surviving on the battle field, and is in strict contrast to Adrian Leverkühn's determined autoinfection with Lues with the aim of artistic perfection and the creative break-through of "Doctor Faustus". Hans Castorp's regression and self-fragmentation within the decadent-morbid atmosphere of the sanatorium lead to his storming into the battles of the First World War as a last and existential crisis; it is here where finally the individual and national fate are merging. Hans Castorp becomes the paradigma of the German pre-war bourgeoisie and its crisis-prone development.

  3. Managing crises through organisational development: a conceptual framework.

    Science.gov (United States)

    Lalonde, Carole

    2011-04-01

    This paper presents a synthesis of the guiding principles in crisis management in accordance with the four configurational imperatives (strategy, structure, leadership and environment) defined by Miller (1987) and outlines interventions in organisational development (OD) that may contribute to their achievement. The aim is to build a conceptual framework at the intersection of these two fields that could help to strengthen the resilient capabilities of individuals, organisations and communities to face crises. This incursion into the field of OD--to generate more efficient configurations of practices in crisis management--seems particularly fruitful considering the system-wide application of OD, based on open-systems theory (Burke, 2008). Various interventions proposed by OD in terms of human processes, structural designs and human resource management, as well as strategy, may help leaders, members of organisations and civil society apply effectively, and in a more sustainable way, the crisis management guiding principles defined by researchers. © 2011 The Author(s).

O estudo toma como corpus discursivo a revista Veja, especialmente reportagens produzidas a partir de 2001, em que enunciações ocupadas por terror e medo se tornam evidentes na mídia em análise. Discussões acerca do medo em Zigmunt Bauman, biopoder/biopolítica em Michel Foucault e cultura a partir de estudiosos do campo da Educação Ambiental são tomados como aportes teóricos desse estudo. Nas reportagens em evidência, há um forte chamamento para riscos e perigos quanto à continuidade de vida na Terra atrelado ao convite para que participemos da grande campanha mundial. Pensarmos possibilidades de enfrentar medos líquidos modernos, produzindo outros modos de nos relacionarmos com o ambiente, é um dos desafios dessa pesquisa.

    The media are important actors in humanitarian crisis management and resolution, both in the countries facing the crises and in the rest of the world. Based on an inductive approach to a news sample from four Spanish newspapers, this study analyses the news frames used in the coverage of countries facing humanitarian crises. Results show that, with certain differences between countries, the Spanish press frames these countries as being theatres of war and violence, Islamic terrorism, and crim...

    Orientation: Crises that threaten an organisation’s continued existence cannot be seen in isolation when considering the perception of threats to individual job security. These threats often go hand in hand with employee panic. Research purpose: The aim of this study was to establish a model to assist organisations in managing employee emotionality and panic during times of crisis. Motivation for the study: Environmental crises threaten organisations’ existence, threatening employees’...

  13. THE IMPLICATIONS OF LIQUIDITY CRISES IN THE CONTEXT OF EMERGING CAPITAL MARKET

    This article aims to highlight the implications of liquidity crises in the context of emerging capital market. Capital markets, and especially emerging capital market appear to behave notably differently during periods of liquidity crises in comparison with periods of stability. The concept of emerging capital market itself is in obvious antithesis to the idea of financial equilibrium. This particular category of capital markets is characterized in a certain measure by profound institutional,...

    Canada needs a policy framework and new governance structure beyond what is in place to reduce the potential for future financial crises. The authors make the case for establishing a formal committee with a mandate to identify potential systemic risks and to act promptly before they materialize. While Canada's system of regulating and supervising financial institutions might hold up as a model of good performance, changes can and should be made, say Jenkins and Thiessen. Future crises undoubt...

    Models of financial crises based on distortions in capital markets have strong implications for the behavior of investors leading up to crises. In this paper we evaluate the hypothesis that deregulation of financial markets in Korea provided the incentives and opportunities for a sequence of capital inflows and crisis. We show that deregulation was associated with a sharp declines in the franchise value of Korean banks. Banks responded by expanding their balance sheets and accumulating high r...

    Communicable disease crises can endanger the health care system and often require special guidelines. Understanding reasons for nonadherence to crisis guidelines is needed to improve crisis management. We identified and measured barriers and conditions for optimal adherence as perceived by 4 categories of health care professionals. In-depth interviews were performed (n = 26) to develop a questionnaire for a cross-sectional survey of microbiologists (100% response), infection preventionists (74% response), public health physicians (96% response), and public health nurses (82% response). The groups were asked to appraise barriers encountered during 4 outbreaks (severe acute respiratory syndrome [SARS], Clostridium difficile ribotype 027, rubella, and avian influenza) according to a 5-point Likert scale. When at least 33% of the participants responded "strongly agree," "agree," or "rather agree than disagree," a barrier was defined as "often experienced." The common ("generic") barriers were included in a univariate and multivariate model. Barriers specific to the various groups were studied as well. Crisis guidelines were found to have 4 generic barriers to adherence: (1) lack of imperative or precise wording, (2) lack of easily identifiable instructions specific to each profession, (3) lack of concrete performance targets, and (4) lack of timely and adequate guidance on personal protective equipment and other safety measures. The cross-sectional study also yielded profession-specific sets of often-experienced barriers. To improve adherence to crisis guidelines, the generic barriers should be addressed when developing guidelines, irrespective of the infectious agent. Profession-specific barriers require profession-specific strategies to change attitudes, ensure organizational facilities, and provide an adequate setting for crisis management.

    The perception, acceptability and management of risks are social construction. Consequently, in managing public health crises, the gap between facts, beliefs and feelings tests the responsiveness of official institutions to health alarms that can be objective, potential, or imaginary. On balance, a strong point of the Spanish experience of health crises is the presence of clinicians and public health officers working in an organization capable of responding adequately, although the quasi-federal Spanish political structure has both advantages and disadvantages. Weaknesses include the low profile given to public health and a management structure that relies too heavily on partitocracy. The management of these crises could be improved by transferring greater scope to health professionals in decisions about crisis identification and management (with transparency) and limiting bureaucratic inertia. For some, health crises involve visibility or business opportunities (not always legitimate). Therefore, the perception of crisis will increasingly rest less in the hands of experts and more in those of groups interested in spreading these crises or in providing solutions. While progress is needed to develop participation in strategies to respond to emerging crises, even more essential is the involvement of all healthcare levels in their preparation and dissemination.

    Throughout economic history, the global economy has experienced recurring crises. The persistent recurrence of such economic crises calls for an understanding of their generic features rather than treating them as singular events. The global economic system is a highly complex system and can best be viewed in terms of a network of interacting macroeconomic agents. In this regard, from the perspective of collective network dynamics, here we explore how the topology of the global macroeconomic network affects the patterns of spreading of economic crises. Using a simple toy model of crisis spreading, we demonstrate that an individual country's role in crisis spreading is not only dependent on its gross macroeconomic capacities, but also on its local and global connectivity profile in the context of the world economic network. We find that on one hand clustering of weak links at the regional scale can significantly aggravate the spread of crises, but on the other hand the current network structure at the global scale harbors higher tolerance of extreme crises compared to more "globalized" random networks. These results suggest that there can be a potential hidden cost in the ongoing globalization movement towards establishing less-constrained, trans-regional economic links between countries, by increasing vulnerability of the global economic system to extreme crises.

    Historical and contemporary experience suggests that science plays an increasingly critical role in governmental and institutional responses to major environmental crises. Recent examples include major western wildfires (2009), the Deepwater Horizon oil spill (2010), the Fukushima nuclear accident (2011), and Hurricane Sandy (2012). The application of science during such crises has several distinctive characteristics, as well as essential requirements if it is to be useful to decision makers. these include scope conditions that include coupled natural/human systems, clear statement of uncertainties and limitations, description of cascading consequences, accurate sense of place, estimates of magnitude of impacts, identification of beneficiaries and those adversely affected, clarity and conciseness, compelling visualization and presentation, capacity to speak "truth to power", and direct access to decision makers. In this chapter, we explore the role and significance of science – including all relevant disciplines and focusing attention on the social sciences – in responding to major environmental crises. We explore several important questions: How is science during crisis distinctive? What social science is most useful during crises? What distinctive characteristics are necessary for social science to make meaningful contributions to emergency response and recovery? How might the social sciences be integrated into the strategic science needed to respond to future crises? The authors, both members of the Department of the Interior's innovative Strategic Sciences Group, describe broad principles of engagement as well as specific examples drawn from history, contemporary efforts (such as during the Deepwater Horizon oil spill), and predictions of environmental crises still to be confronted.

    Full Text Available Once a humanitarian disaster receives coverage in the global media, the international community usually mobilises to reduce the most severe consequences. However people in Chad are experiencing endemic crises that are detached from speci!c triggers, and they are not receiving any international assistance to help relieve the hardships they face. "is study involves 111 migrant households from central Chad that, as a result of war and drought, have lost everything and now have to live in squatter areas of N’Djamena and Mongo, facing uncertainty and threats while negotiating their livelihoods. Qualitative and quantitative methods have been combined in this study to reveal the intriguing story of their daily lives in the face of complex and endemic crises. Anthropometric and health data were generated to determine the nutritional status of mothers and their children under !ve. Life histories, in-depth interviews and participatory observation allowed the researchers to capture the negotiation strategies they use to access food and shelter, their experiences of food insecurity and sanitary vulnerability, and the consequences these have on daily life. Results indicate that 62% of households were female headed, there were high rates of acute (40-50% and chronic (35-40% malnutrition and 46% of the mothers were underweight and anaemic. Infant mortality rates were also high at 30%-42% and 97% of the children had had incomplete or no vaccinations. No households had access to clean water, sanitation or public-health services. Endemic corruption and abuse by the authorities were identi!ed as major sources of day-to-day insecurity. Theese migrants were not expecting any improvement in their livelihoods in the foreseeable future and saw these miserable conditions as normal.

    Blood ammonia and glutamine levels are used as biomarkers of control in patients with urea cycle disorders (UCDs). This study was undertaken to evaluate glutamine variability and utility as a predictor of hyperammonemic crises (HACs) in UCD patients. Methods The relationships between glutamine and ammonia levels and the incidence and timing of HACs were evaluated in over 100 adult and pediatric UCD patients who participated in clinical trials of glycerol phenylbutyrate. Results The median (range) intra-subject 24-hour coefficient of variation for glutamine was 15% (8–29%) as compared with 56% (28%–154%) for ammonia, and the correlation coefficient between glutamine and concurrent ammonia levels varied from 0.17 to 0.29. Patients with baseline (fasting) glutamine values >900 µmol/L had higher baseline ammonia levels (mean [SD]: 39.6 [26.2] µmol/L) than patients with baseline glutamine ≤900 µmol/L (26.6 [18.0] µmol/L). Glutamine values >900 µmol/L during the study were associated with an approximately 2-fold higher HAC risk (odds ratio [OR]=1.98; p=0.173). However, glutamine lost predictive significance (OR=1.47; p=0.439) when concomitant ammonia was taken into account, whereas the predictive value of baseline ammonia ≥ 1.0 upper limit of normal (ULN) was highly statistically significant (OR=4.96; p=0.013). There was no significant effect of glutamine >900 µmol/L on time to first HAC crisis (hazard ratio [HR]=1.14; p=0.813), but there was a significant effect of baseline ammonia ≥ 1.0 ULN (HR=4.62; p=0.0011). Conclusions The findings in this UCD population suggest that glutamine is a weaker predictor of HACs than ammonia and that the utility of the predictive value of glutamine will need to take into account concurrent ammonia levels.

    Full Text Available Background: Abdominal injuries contribute significantly to battlefield trauma morbidity and mortality. This study sought to determine the incidence, demographics, clinical features, spectrum, severity, management, and outcome of abdominal trauma during a civilian conflict. Materials and Methods: A prospective analysis of patients treated for abdominal trauma during the Jos civil crises between December 2010 and May 2012 at the Jos University Teaching Hospital. Results: A total of 109 victims of communal conflicts with abdominal injuries were managed during the study period with 89 (81.7% males and 20 (18.3% females representing about 12.2% of the total 897 combat related injuries. The peak age incidence was between 21 and 40 years (range: 3–71 years. The most frequently injured intra-abdominal organs were the small intestine 69 (63.3%, colon 48 (44%, and liver 41 (37.6%. Forty-four (40.4% patients had extra-abdominal injuries involving the chest in 17 (15.6%, musculoskeletal 12 (11%, and the head in 9 (8.3%. The most prevalent weapon injuries were gunshot 76 (69.7%, explosives 12 (11%, stab injuries 11 (10.1%, and blunt abdominal trauma 10 (9.2%. The injury severity score varied from 8 to 52 (mean: 20.8 with a fatality rate of 11 (10.1% and morbidity rate of 29 (26.6%. Presence of irreversible shock, 3 or more injured intra-abdominal organs, severe head injuries, and delayed presentation were the main factors associated with mortality. Conclusion: Abdominal trauma is major life-threatening injuries during conflicts. Substantial mortality occurred with loss of nearly one in every 10 hospitalized victims despite aggressive emergency room resuscitation. The resources expenditure, propensity for death and expediency of timing reinforce the need for early access to the wounded in a concerted trauma care systems.

    Full Text Available Safety and security are the most important issues to tourist while traveling and the first aspect they consider is to be protected from hazards. Emergency planning and preparedness for a crisis are the most significant components of dealing with disasters. Hospitality practitioners noticed a rising number of natural and man-made crises that harm the hospitality industry, regarding its vulnerability to crisis and internal and external hazards. By using secondary data, this study aims to shed some light on this issue, contributing to knowledge and awareness on emergency preparedness for the hospitality industry. Moreover, the study aims to explain the management’s commitment to adopt, develop, and update emergency plans. The results of this study explain that tourism as an international mobile industry must respond to internal and external hazards such as disease movement and terrorist attacks. Marketing safety is important to promote hotels and tourist destinations to the guests and holiday advisors. Hotels have a long history of being a soft target for terrorist attacks, as can be seen in several accidents that have shaken the hotel industry in the past few decades. Hotels invest a lot to install protective techniques, but terrorists are becoming more organized. Practitioners propose disaster management frameworks using several measurements. Recovery from crisis and learning help business retention that minimizes negative impacts and prevent losses. Finally, evaluation and feedback are very important to overcome the hazards and return to normal, as well as adopting new ideas to deal with emergencies. Single- and double-loop organizational learning should benefit proactive preparedness.

    Full Text Available RESUMO Comparado à organização política do Principado, o regime imperial da Antiguidade Tardia obteve um controle muito maior sobre a circulação da informação política em decorrência da centralização do poder e do número ainda maior de funcionários qualificados dedicados a coligir, cotejar e recuperar informações em todo o Império. Ainda assim, a vastidão do Império Romano e a lentidão das comunicações continuavam a representar as principais ameaças ao poder absolutista, especialmente nos momentos de crises políticas, quando a própria ausência de informações oficiais alimentava os canais subterrâneos e incontrolados de notícias. Do ponto de vista da plebe urbana e dos atores políticos locais, o recurso a essas notícias clandestinas que nós chamamos de "boatos" podia representar uma tentativa de avaliar a abertura de oportunidades para a ação em um ambiente político marcado por uma profunda incerteza. O objetivo deste artigo é explorar como a plebe urbana, as facções religiosas ou seus líderes percebiam (e encorajavam a difusão de notícias sobre as mudanças no poder imperial como uma "janela de oportunidades" e como uma forma de organizar uma ação coletiva.

    Cholelithiasis is rarely seen in toddlers and school-aged children, even in the setting of sickle cell anemia. In addition to more common etiologies, such as gastroenteritis, constipation, and urinary tract infection, the differential diagnoses of acute abdominal pain in young children with sickle cell disease include vaso-occlusive pain crisis and splenic sequestration. We describe a case of a toddler with sickle cell disease initially presenting with abdominal pain who was found to have symptomatic cholelithiasis.

    Full Text Available A década de 80, apelidada de “década perdida” no sentido econômico, foi vista por alguns do mesmo modo com relação à participação juvenil (política e socialmente. A principal justificativa para isso pode ser a crise mundial do período. No rastro do processo de redemocratização de muitos países da América Latina, sobravam crises econômicas, sociais e dívidas externas fabulosas. O Brasil, inserido neste processo, se viu envolvido numa crise sem precedentes. As juventudes2 urbanas do período passaram a representar a alienação, a despolitização e a falta de identificação com movimentos sociais, como já fora observado antes. Somando-se a isso, o mundo ainda enfrentava o “fantasma” da Guerra Fria e a clara percepção dos efeitos da globalização, culminando numa eminente crise de identidade que acrescentada à crise econômica, faziam do mundo um grande campo de incertezas.

  12. Global effects of local food-production crises: a virtual water perspective.

    Tamea, Stefania; Laio, Francesco; Ridolfi, Luca

    2016-01-25

    By importing food and agricultural goods, countries cope with the heterogeneous global water distribution and often rely on water resources available abroad. The virtual displacement of the water used to produce such goods (known as virtual water) connects together, in a global water system, all countries participating to the international trade network. Local food-production crises, having social, economic or environmental origin, propagate in this network, modifying the virtual water trade and perturbing local and global food availability, quantified in terms of virtual water. We analyze here the possible effects of local crises by developing a new propagation model, parsimonious but grounded on data-based and statistically-verified assumptions, whose effectiveness is proved on the Argentinean crisis in 2008-09. The model serves as the basis to propose indicators of crisis impact and country vulnerability to external food-production crises, which highlight that countries with largest water resources have the highest impact on the international trade, and that not only water-scarce but also wealthy and globalized countries are among the most vulnerable to external crises. The temporal analysis reveals that global average vulnerability has increased over time and that stronger effects of crises are now found in countries with low food (and water) availability.

    Odemene, Glory C.

    The Niger Delta crises escalated beyond the borders of the Nigerian nation to become an issue that affected individuals and corporations around the world. This study led to the discovery of how the local crises escalated with international implications. This discovery was accomplished by addressing how the Niger Delta crises escalated from villages to international scenes, with notable impacts on the environment, health, safety, security, and financial segments of local, international, private, and corporate entities. Using Sweeny's crisis decision theory and Lazarus and Folkman's coping theory, the study considered the coping strategies of community members, the decisions, and actions they took in response to the management approaches of the government and the oil and gas companies (OGCs). This qualitative study utilized historical narrative to collect data by interviewing 4 participants who lived and worked in the region during the crises. NVivo was used for manual and automatic coding of data, as well as for categorization and connection of codes. Content analysis of identified codes and categories revealed the themes and trends in the experiences narrated by participants. Findings include the root causes, trend of escalation, and management strategies of the government and the OGCs that influenced the crises. These findings will help to influence policies and practices in the region and enhance effective management of current and emerging conflicts, with possibilities of restoring stability and security in the areas and in the nation at large.

    Full Text Available Human progress is stimulated by external threats and pressures. Values distilled from long experience possess the essential knowledge and power needed for continuous development and evolution. Successive waves of foreign invasions following the collapse of the Roman Empire coalesced the tribes of England into a nation state. Centuries of incessant warfare finally compelled the countries of Western Europe to evolve a regional union within which war has become unthinkable. Most recently, the rising incidence of terrorism has compelled national security institutions to forge a network for global coordination unimaginable during the Cold War. Challenges met are converted into opportunities. Opportunities missed degenerate into problems. All crises are psychological in origin. The remedy always calls for a change of attitude and values. The greatest threats confronting human beings today do not come from external aggressors. They are the result of problems that affect humanity as a whole and can only be addressed collectively by the entire human race. International financial instability, unemployment, terrorism, proliferation of nuclear weapons and climate change are indications that humanity is entering a higher phase in social evolution that compels us to evolve more effective instruments for governance at the global level. No nation or group of nations acting on its own can protect itself from these threats. Effective action to address these issues is unlikely to come from governments whose source of power and very identity are based on national sovereignty and separateness. Mechanisms for global governance will not be effective unless founded upon universally accepted values in fact as well as in principle, a condition violated by the undemocratic character of the UN system. Power relents only in the face of greater power. Power that exceeds that of the five permanent members of the Security Council can only come from representatives of humanity

    1986-01-01

    Time and again, couples have to cope with changes and challenges (e.g. choice of partner, marriage, childbirth and upbringing, retirement, infirmity, etc.) which cause stress and crises to their relationship. They may try to forestall such pressing changes by entering a collusion and clinging to well-established solutions. In the therapy of chronic relational crises, it has to be taken into consideration that in case of a divorce, the partners often have no real possibilities to make a new start, and that it is often more useful to support the actual coping strategies of the couple. In urgent crises, it is recommended that the therapist structures even cuts off the partners' interactions through separation or the intervention of third parties. Only when calm has been obtained should the actual conflict be treated.

    The aim of this study was to examine predictors of ammonia exposure and hyperammonemic crises in patients with urea cycle disorders. The relationships between fasting ammonia, daily ammonia exposure, and hyperammonemic crises were analyzed in >100 patients with urea cycle disorders. Fasting ammonia correlated strongly with daily ammonia exposure (r = 0.764; P 200% (P urea cycle disorder subtype, dietary protein intake, or blood urea nitrogen. Fasting glutamine correlated weakly with daily ammonia exposure assessed as 24-hour area under the curve and was not a significant predictor of hyperammonemic crisis. Fasting ammonia correlates strongly and positively with daily ammonia exposure and with the risk and rate of hyperammonemic crises, suggesting that patients with urea cycle disorder may benefit from tight ammonia control.

    2018-02-01

    Mexico is considered a regional economic and political powerhouse because of the size of its economy, and a large population in constant growth. However, this same growth accompanied by management and governance failures are causing several water crises across the country. The paper aims at identifying and analyzing the drivers of water crises. Water authorities seem to focus solely on large infrastructural schemes to counter the looming water crises, but fail to structure a set of policies for the improvement of management and governance institutions. The paper concludes with the implications of a business-as-usual policy based on infrastructure for solving water problems, which include a non-compliance to the human right to water and sanitation, ecosystem collapses and water conflicts.

  18. Impact of crises on the development of tourism in the world

    2016-01-01

    Full Text Available In terms of global tourism business, tourism constantly faces crises that affect its development. At the beginning of the XXI century, several significant crises have had a negative effect on the world tourism industry, starting with the terrorist attacks on the USA, epidemics, the global economic crisis, natural disasters, political crises, etc. Tourism has resulted in the decline in tourism traffic and tourism receipts, with major or minor impacts on global tourism trends. The largest negative effects realized under the influence of global economic crisis, when the indicators of tourism development were poor throughout the world. To adequately manage the crisis in tourism, certain preventive measures are introduced so as to forestall the outbreak of the crisis and mitigate the negative effects upon its outbreak. Regardless of the type and duration of the crisis events, tourism has so far shown remarkable resilience.

    Full Text Available Levando em conta o número restrito de casos em âmbito internacional e a ausência de publicações na literatura nacional, os autores apresentam três casos de crises motoras focais induzidas por movimentos em pacientes diabéticos com mais de 50 anos de idade. As crises eram numerosas, sendo também desencadeadas ao serem assumidas determinadas posturas. Em dois casos havia hiperglicemia não cetótica. Todos os pacientes apresentavam hemiparesia e, em dois, tal déficit desapareceu após o cotnrole das crises. No outro paciente a hemiparesia era decorrente de acidente vascular cerebral isquêmico instalado 6 meses antes. Síndrome parietal transitória foi observada nos três pacientes. O EEG crítico mostrou, em dois pacientes, descargas na região parieto-occipital e, em um, na região temporal média contralateral. As crises foram resistentes aos anticonvulsivantes, só havendo controle com o tratamento dos distúrbios metabólicos. São discutidos aspectos clínico-eletren-cefalográficos e etiopatogênicos. A pesquisa do caráter reflexo das crises e a dosagem da glicemia devem ser feitas em todos os pacientes idosos com crises motoras focais, face às implicações de ordem terapêutica e prognóstica.

  1. Basel III and prudent risk management in banking: Continuing the cycle of fixing past crises

    Directory of Open Access Journals (Sweden)

    2012-09-01

    Full Text Available Financial crises have had a significant impact on bank regulation and supervision. Reforms are often focussed on correcting past failings. Following the 2007 financial crisis, Basel III reforms have been introduced with a view to promote a more resilient banking sector and to improve the banking sector’s ability to absorb shocks arising from financial distress. A review of the Basel III reforms and the literature on the link between capital adequacy regulations and bank stability indicates that these regulations are unlikely to prevent the failure of banks resulting in systemic crises

    The paper deals with the results of observations over 62 patients (55 females and 7 males) from the age of 42-76 with climacteric spondilopathy. The following syndromes of the nervous system lesions were revealed: neuralgic syndrome, middle and lower thoracal radiculoneuritis, the syndrome of vegetative sympatoganglionitis, myelopathy. Special attetion was given to the specificity of the nervous system lesions in patients with climacteric spondilopathy which was characterized by a tendency to vegetative-visceral crises. The author recommends a scheme of a comprehensive treatment of patients with climacteric spondilopathy with vegetative-vascular and visceral crises. This treatment includes androgen-estrogen preparations, anabolic steroids, thyrocalcitonine and symptomatic treatment.

    Against the background of the acknowledged importance of off-balance-sheet exposures in the sub prime crisis, we seek to investigate whether this was a new phenomenon or common to earlier crises. Using a logit approach to predicting banking crises in 14 OECD countries we find a significant impact of a proxy for the ratio of banks‟ off-balance-sheet activity to total (off and on balance sheet) activity, as well as capital and liquidity ratios, the current account balance and GDP growth.

    Economic growth in Vietnam has been fairly resilient to the global commodity and financial crises, but it is unclear why. In addition, the impact of the crises on employment and poverty is in dispute. We develop a dynamic computable general equilibrium model to decompose impacts and estimate...... distributional outcomes. Our results indicate that the 2008 commodity crisis increased employment and reduced poverty by favouring labour-intensive exports, especially in agriculture.

  7. Trichobezoar in a patient with sickle cell anemia: A pain crisis is not always to blame

    Directory of Open Access Journals (Sweden)

    M.S. El-Mekkawy

    2014-09-01

    Full Text Available Trichobezoar, a ball of hair in the stomach, is an under-diagnosed problem that should be considered in patients with an upper abdominal pain and mass, weight loss, and bowel obstruction especially in young girls with underlying psychiatric disorder or mental retardation. Patients with sickle cell disease are susceptible to experiencing pica including, in rare occasions, trichophagia that could lead to formation of a trichobezoar, resulting in serious abdominal complications which are likely to be confused with ordinary vaso-occlusive pain crises. Here we present the rare case of gastric trichobezoar in a 9 year old girl with sickle cell anemia.

  8. Use of piracetam improves sickle cell deformability in vitro and in vivo.

    Gini, E K; Sonnet, J

    1987-01-01

    Microsieving diluted suspensions of oxygenated sickle cell anaemia (HbSS) cells on polycarbonate filters shows that piracetam improves the red cell deformability in vitro. In vivo an oral intake of 160 mg/kg/day divided in four doses enhances the HbSS cell deformability as actively as it does in in vitro experiments. The drug is also able partially to restore the impaired deformability of physiologically deoxygenated HbSS cells. These findings are consistent with the results of clinical trials, which show that continuous treatment with piracetam reduces the incidence of vaso-occlusive crises in patients with sickle cell disease.

  14. Comparing emerging and mature markets during times of crises: A non-extensive statistical approach

    Namaki, A.; Koohi Lai, Z.; Jafari, G. R.; Raei, R.; Tehrani, R.

    2013-07-01

    One of the important issues in finance and economics for both scholars and practitioners is to describe the behavior of markets, especially during times of crises. In this paper, we analyze the behavior of some mature and emerging markets with a Tsallis entropy framework that is a non-extensive statistical approach based on non-linear dynamics. During the past decade, this technique has been successfully applied to a considerable number of complex systems such as stock markets in order to describe the non-Gaussian behavior of these systems. In this approach, there is a parameter q, which is a measure of deviation from Gaussianity, that has proved to be a good index for detecting crises. We investigate the behavior of this parameter in different time scales for the market indices. It could be seen that the specified pattern for q differs for mature markets with regard to emerging markets. The findings show the robustness of the stated approach in order to follow the market conditions over time. It is obvious that, in times of crises, q is much greater than in other times. In addition, the response of emerging markets to global events is delayed compared to that of mature markets, and tends to a Gaussian profile on increasing the scale. This approach could be very useful in application to risk and portfolio management in order to detect crises by following the parameter q in different time scales.

    Directory of Open Access Journals (Sweden)

    Murat Türker

    2015-09-01

    Full Text Available The basic lessons obtained from financial turbulences all over the wor ld are the need to spot main causes, identify the triggering risk factors and consequently develop resolution plans for the potential financial crises, which include the establishment of a sound and strong financial system with strengthened institutional and structural bodies. Accurately and timely detection of the main causes that trigger financial fragilitiesemerging from currency, debt and banking is supposed to guide regulators to find "to the point" solutions to the fragility problems and to isolate their effects. Since in the Turkey case, financial crises were observed to occur in the form of twin crises or triplet crises, in this paper, we put forward Turkey-specific diagnoses and suggestions. Thus, the main factors that triggered financial turmoils in Turkey's last quarter century are low GDP, inadequate equity capital, insufficient bank returns, poor FX reserve, high inflation, short position-hot money policy, capital outflows, manipulative credit ratings and bank inertia, namely a trade off betweencredit transactions and risk-free investment vehicles

    Full Text Available L’Union européenne est durement affectée par la crise des dettes souveraines. Cette crise peut être interprétée comme la conséquence de plusieurs faits importants : une absence de leadership européen, des inégalités fortes parfois anciennes entre les performances macroéconomiques des pays membres, des faiblesses structurelles déjà observables avant la crise dans certains pays. Mais le principal facteur de fragilité de l’Union européenne réside dans sa division interne. Tant que la problématique de l’intégration européenne ne sera pas appropriée par les citoyens européens eux-mêmes et tant que certaines politiques ne seront pas davantage coordonnées, l’Union restera sur le fil du rasoir. Cette crise met en lumière l’essoufflement d’un certain modèle d’intégration. Dans cet article, on explore ces problématiques avec un regard géographique.

    Full Text Available Resumo: Crises de marca, decorrentes de falhas no produto, têm se tornado mais frequentes em razão do aumento da complexidade dos produtos. As crises geradas por campanhas de recall são únicas, inesperadas e podem gerar deterioração da relação favorável estabelecida entre a marca e o consumidor, afetar a imagem de marca e reduzir o brand equity. Suas consequências envolvem prejuízos financeiros de curto e longo prazo para a marca, para a empresa e, eventualmente, para a categoria como um todo. Este artigo é fruto de uma pesquisa exploratória qualitativa realizada por meio de um estudo de caso único na indústria de alimentos. Seu objetivo é verificar empiricamente a aplicação das teorias sobre crise de marca e recall em um caso brasileiro recente. Os resultados encontrados estão alinhados com as suposições elaboradas com base no referencial teórico. Como contribuição adicional para o tema, o estudo apresenta o efeito de uma crise real ao longo do tempo.

    Full Text Available One of the sociological features of the current economic crises had been its beginning as a media fact rather than economic reality for ordinary people in Poland. Until the very end of 2008 the offi cial strategy of Polish government was denying of present of any economic crises in Poland: “The Polish economy as well as Polish banking system are used to be healthy and in good conditions and we will be suffer a little slow done because we are not an island”. Unfortunately it occurs not to be true.Based on discourse analysis of two major Polish daily and two weekly we would like to show the evolution of narrative describing crises in global terms and particularly at the domestic market. What was the picture of global crises at the beginning of this discussion, how it supposed to affect Poland, who serve as experts and opinion givers and finally how through the language we can observe the change from ‘slow down’ to ‘crises’? This are basic questions we would like to answer in our text.

  19. Bond markets and banking crises in emerging market economies: The role of institutions

    Directory of Open Access Journals (Sweden)

    Boukhatem Jamel

    2012-01-01

    Full Text Available This paper deals with the question of knowing if countries whose activity of financing is mainly bank based face crises more expensive than those where the bond markets are broader and more developed. The results of the empirical tests on a panel of emerging countries suggest that bank based financial systems are associated with crises slightly more expensive, whereas the relationship between the bond markets and the crises’ costs is fragile. Moreover, financial systems where bond markets play an important role are associated with a higher growth of the production, and this, independently of the presence or not of crises. The consideration of the combined effect of financial liberalization and institutional framework on the bond markets development shows the importance of the direction of the financial liberalization. We join in this case one of the most significant aspects of the “sequencing” theorized by McKinnon (1973. Finally, an effective prudential regulation tends to reduce significantly the probability of occurrence of banking crises.

    Full Text Available Este artigo discute a crise ambiental por meio de um diálogo entre a psicanálise, filosofia e ciências sociais. Busca-se introduzir um eixo comum de compreensão das relações entre a psiquê e a natureza, a partir de um texto reflexivo sobre a natureza humana, sua complexidade e suas sociopatias. A crise socioambiental em que vivemos é tratada a partir das seguintes proposições: (i a humanidade se distanciou da sua condição natural; (ii a humanidade pode estar psicologicamente doente; (iii a humanidade não está moralmente apta para delegar a superação da crise às futuras gerações, pois vivemos num simulacro que envolve consumismo e alienação. Conclui-se que há uma dimensão subjetiva na raiz da crise ambiental, de cuja análise depende a solução real do impasse civilizacional com o qual nos defrontamos.

  6. Vulnerability of countries to food-production crises propagating in the virtual water trade network

    In recent years, the international trade of food and agricultural commodities has undergone a marked increase of exchanged volumes and an expansion of the trade network. This globalization of trade has both positive and negative effects, but the interconnectedness and external dependency of countries generate complex dynamics which are often difficult to understand and model. In this study we consider the volume of water used for the production of agricultural commodities, virtually exchanged among countries through commodity trade, i.e. the virtual water trade. Then, we set up a parsimonious mechanistic model describing the propagation, into the global trade network, of food-production crises generated locally by a social, economic or environmental event (such as war, economic crisis, drought, pest). The model, accounting for the network structure and the virtual water balance of all countries, bases on rules derived from observed virtual water flows and on data-based and statistically verified assumption. It is also tested on real case studies that prove its capability to capture the main features of crises propagation. The model is then employed as the basis for the development of an index of country vulnerability, measuring the exposure of countries to crises propagating in the virtual water trade network. Results of the analysis are discussed within the context of socio-economic and environmental conditions of countries, showing that not only water-scarce, but also wealthy and globalized countries, are among the most vulnerable to external crises. The temporal analysis for the period 1986-2011 reveals that the global average vulnerability has strongly increased over time, confirming the increased exposure of countries to external crises which may occur in the virtual water trade network.

    Sickle cell disease is one of the most common genetic disorders. Sickle cell crises in which irregular and dehydrated cells contribute to blocking of blood vessels are characterised by episodes of pain. Treatment is mainly supportive and symptomatic. In vitro studies with piracetam indicate that it has the potential for inhibition and a reversal of the process of sickling of erythrocytes. This is an update of a previously published Cochrane review. To assess the effectiveness of piracetam for reducing the incidence of painful sickle cell disease crises. We searched the Cochrane Cystic Fibrosis and Genetic Disorders Group Haemoglobinopathies Trials Register which comprises of references identified from comprehensive electronic database searches and handsearches of relevant journals and abstract books of conference proceedings.Last search of the Group's Haemoglobinopathies Trials Register: 21 September 2015. Randomised controlled trials comparing orally administered piracetam to placebo or standard care in people, of all ages and both sexes, with sickle cell disease. Two authors independently assessed trial quality and extracted data. Trial authors were contacted for additional information. Adverse effects data were collected from the trials. Three trials involving 169 participants were included in the review. A limited amount of data addressing some of the primary and some of the secondary outcomes were provided, but data were incomplete and based on un-validated assumptions used in the evaluation of outcomes. One trial reported a reduction in the number of pain crises and their severity with active intervention than placebo but presented no data to confirm these results. A second trial presented a monthly global pain score based on the number of sickle cell crises and severity of pain but included no separate data for these primary outcomes. Although there was no significant difference between the piracetam and placebo periods for the number of days of

    Full Text Available O final do século XIX foi marcado, para Brasil e Argentina, por crescimento e instabilidade na economia. Neste período, ocorreram duas importantes crises econômicas, que ficaram conhecidas como crise Baring (na Argentina e crise do Encilhamento (no Brasil. Este artigo tem o objetivo de apresentar as conexões existentes entre essas duas crises e a conjuntura da economia-mundo capitalista das últimas décadas do século XIX, enfatizando o problema da dívida externa e da política econômica, e re-organizando algumas contribuições da historiografia econômica por meio da metodologia da "encompassing comparison" e da teoria dos ciclos mundiais de endividamento. O artigo mostra que ambas as crises estiveram condicionadas pela dinâmica da economia-mundo capitalista, especialmente pelos fluxos mundiais de capital, não sendo resultados exclusivos de políticas econômicas nacionais.The end of the 19th century was characterized by economic growth and instability in Brazil and Argentina. In this period, two important economic crises took place - the Baring Crisis (in Argentina and the Encilhamento Crisis (in Brazil. The aim of this paper is to present the connections between these two crises and the dynamics of the capitalist world-economy of the end of the 19th century, focusing on the problems of external debt and economic policy and re-organizing some contributions of economic historiography through the methodology of "encompassing comparison" and of the world debt cycles' theory. The paper concludes that both crises were influenced by the dynamics of the capitalist world-economy, especially by the international flows of capital, and that they were not exclusive results of national economic policies.

    Full Text Available Objective: The objective of this study was to verify the evolution of pregnancies in sickle cell patients followed at one institution over a period of 12 years (January 2000 to June 2012. Methods: The study evaluated 34 pregnant women with sickle cell disease with a mean age of 23.9 ± 5.3 years. The incidence of obstetric complications, non-obstetric complications linked to sickle cell disease and complications in the newborn were analyzed. Results: A total of 26% of the cases reported previous miscarriages, 20% had preterm labor, 10% had pre-eclampsia, and 5% had gestational diabetes. Forty-one percent of the deliveries were cesarean sections and 29% of patients required blood transfusions. In respect to sickle cell disease, 62% of patients had vaso-occlusive crises, 29% had acute chest syndrome, 23% had urinary tract infection, 15% had impaired cardiac function and 6% developed pulmonary hypertension. Only one patient died in the postnatal period due to acute chest syndrome. The mean gestational age was 37.8 ± 2.63 weeks, and mean newborn weight was 2.809 ± 643.8 g. There were seven fetal losses, including three stillbirths and four miscarriages. The impact of transfusion therapy on the incidence of maternal–fetal complications during pregnancy was evaluated. Conclusions: Pregnancy in sickle cell patients is still associated with complications. Although no statistical difference was observed between transfused and non-transfused women, there were no deaths (fetal or maternal in transfused patients whereas one maternal death and three stillbirths occurred in non-transfused women. A larger study of sickle cell pregnant women will be necessary to elucidate the actual role of transfusion during pregnancy in sickle cell disease.

  11. Crises financeiras nos anos 1990 e poupança externa

    Directory of Open Access Journals (Sweden)

    Luiz Carlos Bresser-Pereira

    2008-12-01

    Full Text Available Contrary to what conventional economic analysis afirms, the main cause of the financial crises in emerging countries during the 1990s, beginning with Mexico (1994 and ending with the crisis in Argentina (2001 was not primarily fiscal, but the decision by governments to foster growth with foreign savings, i.e., with current account deficits. Since the exchange rate has other determinants besides domestic absorption, the assumption of twin deficits often does not hold. These were balance of payment crises triggered by an overvalued local currency and the high increases in the foreign debt and/or the fast growth of the current account deficit. This led, foreign creditors to suddenly become persuaded that the country faced both liquidity and solvency problems, and to stop rolling over the debt. An econometric test substantiates these claims.

    Extraction of interaction networks from multi-variate time-series is one of the topics of broad interest in complex systems. Although this method has a wide range of applications, most of the previous analyses have focused on the pairwise relations. Here we establish the potential of such a method to elicit aggregated behavior of the system by making a connection with the concepts from percolation theory. We study the dynamical interaction networks of a financial market extracted from the correlation network of indices, and build a weighted network. In correspondence with the percolation model, we find that away from financial crises the interaction network behaves like a critical random network of Erdős-Rényi, while close to a financial crisis, our model deviates from the critical random network and behaves differently at different size scales. We perform further analysis to clarify that our observation is not a simple consequence of the growth in correlations over the crises.

  13. Financial integration and financial development in transition economies: What happens during financial crises?

    Igor Masten

    2011-12-01

    Full Text Available

    This paper provides an empirical analysis of the role of financial development and financial integration in the growth dynamics of transition countries. We focus on the role of financial integration in determining the impact of financial development on growth, distinguishing “normal times” from periods of financial crises. In addition to confirming the significant positive effect on growth exerted by financial development and financial integration, our estimates show that a higher degree of financial openness tends to reduce the contractionary effect of financial crises, by cushioning the effect on the domestic supply of credit. Consequently, the high reliance on international capital flows by transition countries does not necessarily increase their financial fragility. This implies that financial protectionism is a self-defeating policy, at least for transition countries.

    We examined the time series properties of the foreign exchange market for 1990-2008 in relation to the history of the currency crises using the minimum spanning tree (MST) approach and made several meaningful observations about the MST of currencies. First, around currency crises, the mean correlation coefficient between currencies decreased whereas the normalized tree length increased. The mean correlation coefficient dropped dramatically passing through the Asian crisis and remained at the lowered level after that. Second, the Euro and the US dollar showed a strong negative correlation after 1997, implying that the prices of the two currencies moved in opposite directions. Third, we observed that Asian countries and Latin American countries moved away from the cluster center (USA) passing through the Asian crisis and Argentine crisis, respectively.

    2016-01-01

    Full Text Available The media are important actors in humanitarian crisis management and resolution, both in the countries facing the crises and in the rest of the world. Based on an inductive approach to a news sample from four Spanish newspapers, this study analyses the news frames used in the coverage of countries facing humanitarian crises. Results show that, with certain differences between countries, the Spanish press frames these countries as being theatres of war and violence, Islamic terrorism, and crime. From a theoretical perspective, results also suggest that news frames should not be classified either as "generic" or "specific", but that they should instead be placed on a continuous scale ranging from "generic" through to "specific".

  17. Contingency and Political Action: The Role of Leadership in Endogenously Created Crises

    Directory of Open Access Journals (Sweden)

    András Körösényi

    2016-06-01

    Full Text Available Among the recent literature about leadership and crisis situations two main strands are to be observed: structuralist ones mainly treat political leaders as reactive agents who have relatively little room for maneuver, while constructivist ones put greater emphasis on the opportunities in interpreting crises. Our claim is that there is a third analytical possibility mainly neglected in recent literature that is even more voluntaristic than the constructivist approaches. In this scenario, there is no external shock; leaders do not only interpret, but also “invent” crises. To make our claim plausible, we build a conceptual-descriptive typology of the potential relationships between crisis situations and agency. The typology is founded on Kari Palonen’s differentiation between Machiavellian and Weberian types of contingency, but uses his originally conceptual historical argument for analytical purposes. To underpin our theoretical argument, we present short illustrative examples to all three types of crisis scenarios (the structuralist, the constructivist, and the voluntarist one.

    commitment is at the basis of positive employee communicative actions, like advocacy and positive referrals, which finally protect the company’s reputation. After a theoretical exploration of these issues, this chapter presents first a case study showing how continuous internal communication efforts...... and factual communication based on managers’ and company’s actions are crucial in order to build quality relationships with employees. In turn, this leads to positive employee communicative actions when a crisis occurs. Second, it illustrates a survey of Italian companies which examined internal crisis...... reputation.

    Full Text Available The development of civilization made crises an inseparable part of our lives. Crises manifest themselves in almost all social areas and organizations, including educational institutions. The goals of the article are to present a theoretical model of normal, deviant and antisocial behaviors, and discuss the psycho-social characteristics of emotionally disturbed adolescents situated in a residential special education school in the United States. The article also gives an analysis of their most prevalent behavioral crises, escalation stages, as well as nonviolent crisis prevention and intervention strategies. The methods that were used include scientific literature review, analysis of statistical information supplied from different government sources, review and analysis of student records, as well as the author’s analytical reflections in working with emotionally disturbed youngsters in residential special education schools in the United States.The results of the study indicate that scientists from different fields use different terminology to describe socially nonconforming behaviors. The author presents a theoretical model of normal, deviant and antisocial behavior that could enhance better understanding and identification of high risk situations and conduct leading to serious crises. The analysis of student records revealed that most of the adolescents situated in special education residential schools are diagnosed with a number of mental health problems. This suggests that the currently prevailing care and education paradigm in the special education residential schools should shift to a more comprehensive treatment paradigm. The article also discusses the pros and cons of nonviolent crisis intervention. It is the author’s opinion that all special education schools serving children with emotional disorders should adopt one of the nonviolent crisis intervention models and develop and implement crisis management policies, plans and procedures.

    Full Text Available Resumo: Investiga-se se crises de segurança do alimento deslocam para baixo as demandas por carne bovina, suína e de frango no Brasil. Constroem-se três séries de índices de crises de segurança do alimento, um para cada tipo de carne, somando-se o total de notícias na Folha de São Paulo que atenderam a critérios predefinidos de busca. Utilizam-se estas três séries, os preços das carnes e de um bem composto e o gasto per capita com consumo como variáveis explicativas em seis especificações alternativas de um sistema de quatro equações de demanda. Seleciona-se a melhor especificação do modelo por meio de testes ajustados de razão de verossimilhança. Testes com o modelo selecionado não rejeitam a hipótese de que as demandas não são afetadas por crises de segurança do alimento. Conclui-se que se deslocamentos da demanda para baixo em reação a crises de segurança do alimento criam incentivos para que as empresas adotem medidas para produzir um alimento mais seguro, tais incentivos não existem nos setores de carnes no Brasil. Assim, reforça-se a importância e necessidade de um sistema público ativo para regulamentar e estabelecer padrões de segurança da carne no Brasil.

    Full Text Available Os problemas vividos na atualidade, principalmente a grave situação financeira internacional, significam sinal evidente de insuficiência do modelo teórico moderno. Talvez sustentem a própria crise do Estado Constitucional Moderno. Alguns exemplos recentes parecem comprovar tal crise: o complexo de indústrias mundiais de alimentos que arrasa sementes tradicionais acabou por criar uma situação de desequilíbrio alimentar no planeta. Além disso, fatos como  a comercialização mundial do petróleo, o monopólio da comunicação e a realidade virtual manipulável demonstram que a internalização do Poder Público da modernidade provavelmente cederá espaço à transnacionalização desse mesmo Poder Público. Repensar, pois, a Democracia neste momento é fundamental, principalmente em sua vertente transnacional. Todo o mundo “acordado” e afetado pela globalização, faz-se cada vez mais certo que o único poder legítimo é o poder com investidura decidida pela maioria, que se constitui a partir de instrumentos democráticos efetivos.

    2014-06-01

    Full Text Available In this case study, I examine the quality of decision-making under conditions of rapidly evolving urban water crises, and the adaptive policy challenges of building regional resilience in response to both drought and flood. Like other regions of Australia, Southeast Queensland has been subject to substantial cycles of drought and flood. I draw on resilience literature concerning sustainability, together with governance literature on policy change, to explain the changing awareness of urban water crises and the strategic options available for addressing these crises in this case study. The problem of resilience thinking opens up a number of important questions about the efficacy and adaptability of the policy system. The case provides insights into the interplay between the ways in which problems are framed, the knowledge bases required for planning and decision-making, the collaborative governance processes required for managing complex and rapidly evolving issues, and the overall capacity for policy learning over time. Regional resilience was proclaimed as a policy goal by government, but the practices remained largely anchored in traditional technical frameworks. Centralized investment decisions and governance restructures provoked conflict between levels of government, undermining the capacity of stakeholders to create more consensual approaches to problem-solving and limiting the collective learning that could have emerged.

    1981-04-01

    An analysis of the response of American markets to supply crises in world oil markets is presented. It addresses four main issues: the efficiency of the operation of American oil markets during oil supply crises; the problems of both economic efficiency and social equity which arise during the American adaptation process; the propriety of the Federal government's past policy responses to these problems; and the relationship between perceptions of the problems caused by world oil crises and the real economic natures of these problems. Specifically, Chapter 1 presents a theoretical discussion of the effects of a world supply disruption on the price level and supply availability of the world market oil to any consuming country including the US Chapter 2 provides a theoretical and empirical analysis of the efficiency of the adaptations of US oil product markets to higher world oil prices. Chapter 3 examines the responses of various groups of US oil firms to the alterations observed in world markets, while Chapter 4 presents a theoretical explanation for the price-lagging behavior exhibited by firms in the US oil industry. Chapter 5 addresses the nature of both real and imagined oil market problems in the US during periods of world oil market transition. (MCW)

  6. Crises-induced intermittencies in a coherently driven system of two-level atoms

    1993-04-01

    We study the coherent dynamics of a thin layer of two-level atoms driven by an external coherent field and a phase conjugated mirror (PCM). Since the variables of the system are defined on the Bloch sphere, the third dimension is provided by the temporal modulation of the Rabi frequencies, which are induced by a PCM which reflects an electric field with a carrier frequency different from the incident one. We show that as the PCM gain coefficient is changed period doubling leading to chaos occurs. We find crises of attractor merging and attractor widening types related to homoclinic and heteroclinic tangencies respectively. For the attractor merging crises we find the critical exponent for the characteristic time of intermittency versus the control parameter which is given by the gain coefficient of the PCM. We show that during the crises of attractor widening type, another crisis due to attractor destruction occurs as the control parameter is changed. The latter is due to the collision of the old attractor with its basin boundary when a new attractor is created. This new attractor is stable only in a very small interval in the neighborhood of this second crisis. (author). 31 refs, 15 figs

    Full Text Available Crises in company development are a particular subset of management crises. They emerge on various stages of company development, as a result of gradual depletion of effective management solutions. Crisis situations in companies have varied impact on company stakeholders. The paper presents results of empirical studies of factors influencing company relations with market stakeholders and those that facilitate the process of restoring and maintaining any relations that suffered in the course of crises in company development. The authors’ intention was to identify such factors and evaluate their importance, in relation to various stages of company development and the associated types of crisis situations faced by companies. Empirical studies suggest that certain factors may facilitate conflict resolution in matters concerning company relations with market stakeholders, and that the impact of these factors varies depending on the phase of organizational development and the type of the associated crisis situation. It must be noted, that one of the most important factors to influence problem resolution is the perceived honesty of the exchange participants. Moreover, research suggests that opinions on the significance of organizational dependence of exchange participants in the resolution of problems in relations with market stakeholders are varied.

    Full Text Available O debate sobre o governo das sociedades tem ganhado crescente relevo nos meios acadêmico e empresarial desde o fim da década de 1980. Esse maior destaque foi originado por diversos fatores, dos quais se salientam a crise na Ásia, os escândalos financeiros que assolaram grandes empresas cotadas norte-americanas e algumas empresas de auditoria e, mais recentemente, a crise financeira mundial. Embora há muito defendida a necessidade de aperfeiçoar os instrumentos existentes e de descobrir novos mecanismos, de modo a encontrar um sistema de governo das sociedades que minimize os custos de agência, a crise financeira mundial com origem nos EUA veio dar-lhe novo “fôlego”. E, agora, com especial ênfase na banca. Falhas no governo das sociedades, em particular no setor bancário, têm sido apontadas como culpadas pela crise financeira global iniciada em 2007, só comparável à Grande Depressão. Assim, este artigo pretende, em primeiro lugar, apresentar uma caracterização genérica dos mecanismos de governo das sociedades, integrando no estudo os denominados custos de agência e, em seguida, analisar tais mecanismos no setor bancário, estabelecendo uma relação entre eles e a crise financeira. A pesquisa efetuada permite demonstrar a importância dos instrumentos de governo das sociedades na minimização dos custos de agência, nomeadamente no contexto da crise financeira. Ainda que o setor bancário tenha as suas especificidades, a investigação feita indica que existe uma relação entre aqueles instrumentos e a performance dos bancos e que fragilidades no governo das sociedades determinaram em larga medida a crise financeira.

    Background Vaso-occlusive pain crises (VOCs) are the “hallmark” of sickle-cell disease (SCD) and can lead to sympathetic nervous system dysfunction. Increased sympathetic nervous system activation during VOCs and/or pain can result in vasoconstriction, which may increase the risk for subsequent VOCs and pain. Hypnosis is a neuromodulatory intervention that may attenuate vascular and pain responsiveness. Due to the lack of laboratory-controlled pain studies in patients with SCD and healthy controls, the specific effects of hypnosis on acute pain-associated vascular responses are unknown. The current study assessed the effects of hypnosis on peripheral blood flow, pain threshold, tolerance, and intensity in adults with and without SCD. Subjects and methods Fourteen patients with SCD and 14 healthy controls were included. Participants underwent three laboratory pain tasks before and during a 30-minute hypnosis session. Peripheral blood flow, pain threshold, tolerance, and intensity before and during hypnosis were examined. Results A single 30-minute hypnosis session decreased pain intensity by a moderate amount in patients with SCD. Pain threshold and tolerance increased following hypnosis in the control group, but not in patients with SCD. Patients with SCD exhibited lower baseline peripheral blood flow and a greater increase in blood flow following hypnosis than controls. Conclusion Given that peripheral vasoconstriction plays a role in the development of VOC, current findings provide support for further laboratory and clinical investigations of the effects of cognitive–behavioral neuromodulatory interventions on pain responses and peripheral vascular flow in patients with SCD. Current results suggest that hypnosis may increase peripheral vasodilation during both the anticipation and experience of pain in patients with SCD. These findings indicate a need for further examination of the effects of hypnosis on pain and vascular responses utilizing a randomized

    Full Text Available Sickle cell disease (SCD is one of the most common inherited diseases in the world and the patients present notorious clinical heterogeneity. It is known that patients with SCD present activation of the blood coagulation and fibrinolytic systems, especially during vaso-occlusive crises, but also during the steady state of the disease. We determined if the presence of the factor V gene G1691A mutation (factor V Leiden, the prothrombin gene G20210A variant, and methylenetetrahydrofolate reductase (MTHFR C677T polymorphism may be risk factors for vascular complications in individuals with SCD. We studied 53 patients with SCD (60% being women, 29 with SS (sickle cell anemia; 28 years, range: 13-52 years and 24 with SC (sickle-hemoglobin C disease; 38.5 years, range: 17-72 years hemoglobinopathy. Factor V Leiden, MTHFR C677T polymorphism, and prothrombin G20210A variant were identified by PCR followed by further digestion of the PCR product with specific endonucleases. The following vascular complications were recorded: stroke, retinopathy, acute thoracic syndrome, and X-ray-documented avascular necrosis. Only one patient was heterozygous for factor V Leiden (1.8% and there was no prothrombin G20210A variant. MTHFR 677TT polymorphism was detected in 1 patient (1.8% and the heterozygous form 677TC was observed in 18 patients (34%, 9 with SS and 9 with SC disease, a prevalence similar to that reported by others. No association was detected between the presence of the MTHFR 677T allele and other genetic modulation factors, such as alpha-thalassemia, ß-globin gene haplotype and fetal hemoglobin. The presence of the MTHFR 677T allele was associated with the occurrence of vascular complications in SCD, although this association was not significant when each complication was considered separately. In conclusion, MTHFR C677T polymorphism might be a risk factor for vascular complications in SCD.

    Sickle cell disease (SCD) is associated with acute vaso-occlusive crises that trigger painful episodes and frequently involves ongoing, chronic pain. Additionally, both humans and mice with SCD experience heighted cold sensitivity. However, studies have not addressed the mechanism(s) underlying the cold sensitization, nor its progression with age. Here we measured thermotaxis behavior in young and aged mice with severe SCD. Sickle mice had a marked increase in cold sensitivity measured by a cold preference test. Further, cold hypersensitivity worsened with advanced age. We assessed whether enhanced peripheral input contributes to the chronic cold pain behavior by recording from C fibers, many of which are cold-sensitive, in skin-nerve preparations. We observed that C fibers from sickle mice displayed a shift to warmer (more sensitive) cold-detection thresholds. To address mechanisms underlying the cold sensitization in primary afferent neurons, we quantified mRNA expression levels for ion channels thought to be involved in cold detection. These included the Transient Receptor Potential Melastatin 8 (Trpm8) and TRP Ankyrin 1 (Trpa1) channels, as well as the two-pore domain potassium channels, TREK-1 (Kcnk2), TREK-2 (Kcnk4), and TRAAK (Kcnk10). Surprisingly, transcript expression levels of all of these channels were comparable between sickle and control mice. We further examined transcript expression of 83 additional pain-related genes and found increased mRNA levels for endothelin 1 and tachykinin receptor 1. These factors may contribute to hypersensitivity in sickle mice at both the afferent and behavioral levels. Sensory neurons from sickle cell disease mice are sensitized to cold, mirroring behavioral observations, and have increased expression of endothelin 1 and tachykinin receptor 1. PMID:24953902

  14. The Critical Role of Crisis Communication Plan in Corporations’ Crises Preparedness and Management

    Directory of Open Access Journals (Sweden)

    2014-06-01

    Full Text Available Many corporations have a Crisis Management Plan (CMP, which is designed to handle crises. These plans may include crisis response drills, evacuation plans, and standby machines/generators. However, when it comes to communication during a crisis, many organizations are ill-prepared because they lack a Crisis Communication Plan (CCP. Following the September 21, 2013 attack on the Westgate Mall in Nairobi, the public’s praises for the security forces swiftly degenerated into blame, insults, and expressions of betrayal. The government seemed unprepared. There was no clearly spelt out CCP detailing what and when to release information, as well as who and how to make the release. Hence, every step the government took to give updates about the attack and what it was doing to secure the mall and save people was challenged by the media and the public. The lack of a CCP was evident in the presentation of several spokespersons by the authorities, double talk, conflicting messages, and uncertainty on the matter. This paper thus argues that while corporations strive for a variety of strategies for crisis management, there is need to also enshrine CCP in their CMP. It utilizes Coombs’ (2012 three-stage crisis management model that carefully considers the pre-crisis, crisis, and post-crisis stages. Focusing on selected corporations in Kenya that suffered crises between June 1, 2012 and October 30, 2013, this research holds that the crises duration and negative impact could have been lessened if the organizations integrated effective CCP in their CMP.

    Full Text Available Orientation: Crises that threaten an organisation’s continued existence cannot be seen in isolation when considering the perception of threats to individual job security. These threats often go hand in hand with employee panic. Research purpose: The aim of this study was to establish a model to assist organisations in managing employee emotionality and panic during times of crisis. Motivation for the study: Environmental crises threaten organisations’ existence, threatening employees’ livelihood and resulting in employee panic. Panic reduces employees’ contributions. Organisations that are successful harness employee contributions at all times. Research design, approach, and method: A modernist qualitative research methodology was adopted, which included a case study as research strategy, purposive sampling to select 12 research participants, semi-structured interviews for data gathering, focus groups for data verification, and the use of grounded theory for data analysis. Main findings: An organisation’s ability to manage employee panic depends on the relationship between the foundational elements of authentic leadership, crisis readiness, resilience practices, versatile and committed talent, strategic management, quality management, and coherence actions taken during the crisis, which include crisis leadership, ongoing visible communication, mindfulness, work flexibility, and decisions based on the greatest financial need and social support. Practical/managerial implications: The study provides a best-practice option for managing emotionality during crises for the case organisation and other organisations within the vehicle components and other manufacturing industries. Contribution/value-add: The Coherence Hexagons Model is presented as a tool to manage employee panic during crisis.

    Full Text Available Este trabalho analisou a relação entre o comportamento do mercado acionário brasileiro, representado pelo Ibovespa, e os fluxos de capitais estrangeiros direcionados para investimentos em carteira de ações, no período posterior à implantação do Plano Real. Ao longo desse período, foram observadas diversas crises financeiras no âmbito internacional que provocaram instabilidade e volatilidade nos fluxos de capitais estrangeiros. Este trabalho considera as influências sistemáticas dessas instabilidades sobre o Ibovespa, especialmente pela capitalização relativamente pequena do mercado brasileiro de ações. A hipótese de mercado eficiente supõe que os preços das ações, e com isso o Ibovespa, seguem um caminho aleatório e não devem estar sujeitos a influências sistemáticas de outros fatores. A hipótese geral do trabalho é que os fluxos de capitais estrangeiros direcionados para o mercado acionário brasileiro influenciam significativamente o Ibovespa. A hipótese especifica que crises internacionais e nacionais influenciam negativamente os fluxos de capitais estrangeiros nesse segmento e com isso o Ibovespa. A justificação para este trabalho é de que essas influências sistemáticas de crises sobre o Ibovespa são um fator sistemático que limita a hipótese de mercado acionário brasileiro eficiente. Foi realizada uma análise empírica com diferentes modelos mostrando que há evidências de influência sistemática dos fluxos de capital estrangeiro em carteira de ações sobre o Ibovespa. Esses achados limitam, de certa forma, a adequação da hipótese de mercado eficiente para o mercado brasileiro de ações. Essa influência sistemática dos fluxos de capital estrangeiro sobre o Ibovespa pode ser um fenômeno restrito no período analisado, refletindo a alta volatilidade dos fluxos de capitais estrangeiros por causa de crises externas e internas.

    L’objet de cet essai est de proposer non certes des solutions pratiques immédiates au problème contemporain de la crise écologique, mais d’élaborer une réflexion théorique par où l’on apercevra l’insuffisance du principe de souveraineté. Au fondement de l’Etat, la souveraineté est gardienne du particularisme des Etats alors qu’une politique universaliste seule (mondiale ou régionale) s’impose face au désordre environnemental. Ainsi, en contrepartie, l’ouvrage dessine le passage d’une politiqu...

    Full Text Available As sucessivas crises financeiras dos países "emergentes", na segunda metade dos anos 90, despertaram o interesse dos economistas do mainstream, uma vez que os modelos de crises cambiais de primeira geração, desenvolvidos nos anos 80, revelaram-se insuficientes para a compreensão destes eventos. Nesse contexto, foram desenvolvidos novos modelos que incorporaram, como condicionantes destas crises, fatos estilizados, que têm caracterizado o sistema financeiro internacional contemporâneo, dentre os quais os ataques especulativos auto-realizáveis e o comportamento de manada dos investidores estrangeiros. Este artigo pretende apresentar as principais características desses novos modelos. Primeiramente, apresentam-se os modelos desenvolvidos após a crise mexicana, que seguiram a tradição dos modelos de segunda geração desenvolvidos após a crise do Sistema Monetário Europeu. Em seguida, são examinados os modelos que surgem após a crise asiática, denominados "modelos de terceira geração", nos quais a crise cambial está intrinsecamente associada a uma crise bancária. Seguem-se algumas considerações finais.In the 90s, the succession of financial crises in the so called "emergent countries", with characteristics that haven't been considered by the first-generation models of exchange crises developed in the 80s, was followed by the emergency of new models of exchange crisis. The purpose of this article is to present these models, which have introduced in their analytical framework new elements, how the self-fulfilling expectations and the volatility of the capital flows. Firstly, we analyze the models developed after the Mexican crise, which have followed the tradition of the second-generation models that emerged after the European monetary system crise. Secondly, we examine the models developed after the Asian crise, labeled "third generation models", in which the exchange crise is intrinsically linked with a banking crise. We end up

  11. Crises and Collective Socio-Economic Phenomena: Simple Models and Challenges

    Science.gov (United States)

    Bouchaud, Jean-Philippe

    2013-05-01

    Financial and economic history is strewn with bubbles and crashes, booms and busts, crises and upheavals of all sorts. Understanding the origin of these events is arguably one of the most important problems in economic theory. In this paper, we review recent efforts to include heterogeneities and interactions in models of decision. We argue that the so-called Random Field Ising model ( rfim) provides a unifying framework to account for many collective socio-economic phenomena that lead to sudden ruptures and crises. We discuss different models that can capture potentially destabilizing self-referential feedback loops, induced either by herding, i.e. reference to peers, or trending, i.e. reference to the past, and that account for some of the phenomenology missing in the standard models. We discuss some empirically testable predictions of these models, for example robust signatures of rfim-like herding effects, or the logarithmic decay of spatial correlations of voting patterns. One of the most striking result, inspired by statistical physics methods, is that Adam Smith's invisible hand can fail badly at solving simple coordination problems. We also insist on the issue of time-scales, that can be extremely long in some cases, and prevent socially optimal equilibria from being reached. As a theoretical challenge, the study of so-called "detailed-balance" violating decision rules is needed to decide whether conclusions based on current models (that all assume detailed-balance) are indeed robust and generic.

  12. Variations of Young Germans’ Informal Conceptions of Financial and Economic Crises Phenomena

    2014-02-01

    Full Text Available The development of a sound understanding of financial and economic crises phenomena must be considered an important goal within the scope of citizenship, economic and social science education. As with every other educational endeavour, this intention requires solid information about what informal conceptions learners hold about this specific aspect of reality. However, even though this necessity is widely acknowledged, respective theoretical and empirical research is rather scarce. The research to be presented here aims to contribute to filling this gap by exploring variations in young Germans’ common-sense conceptions of financial and economic crises phenomena. The research activities adhere to a comprehensive view of how economic issues should be involved in education. Moreover, a phenomenographic research approach is adopted. This approach was implemented in an interview study with 56 secondary school students in Baden-Württemberg (Germany. Besides this study, the paper also considers evidence from German survey data. In the interview study, four different conceptions (i.e., denial of the crisis, magical thinking, optimism, realism could be reconstructed, which vary with respect to whether students’ awareness of specific facets of the crisis was given or not. In addition, from this study as well as from the survey data, an excessively optimistic attitude was stated in young Germans. This attitude, however, seems to be more a symptom of insecurity and overstrain than a manifestation of a profound comprehension. These results are discussed with regard to the design of formal curricula and instruction.

    GHOUS BUX NAREJO

    2017-04-01

    Full Text Available Pakistan energy demand has grown exponentially over the last 2 decades. Reason behind increasing energy demand is excessive mobility of rural population to cities, rapid progression in industrial and transport sector, lack of policy making and implementation on the developed policies and improvements in living style. At present, Pakistan witness 5000-7000 MW power deficit in summer. To reduce the demand and supply gap, power plants across Pakistan are planned to be installed while some are under development phase. Power expansion plans cannot cope with the current energy shortfall since several years are required for them to get fully operational. Effective energy policy is the only key to address the existing shortfall. This paper discusses the initiatives that may be taken to reduce the power shortfall using energy efficiency and conservation, deployment of microgrids, utilization of renewable energy resources and effective research and development in energy sector. Since another most important issue evaluated in the research regarding the energy crises is energy efficiency and lack of compliance to government regulations for energy efficiency and conservation. Implementation on the policies developed for energy efficiencies and conservation has not been witnessed. Possible solutions on short term basis to lessen the energy crises have also been discussed in the paper

    Full Text Available Urban gardens have been observed to multiply in response to crises. However, the meaning and motivations behind the emergence of gardening movements varies greatly over space and time. In this paper we argue that bottom up urban gardening initiatives taking place in Southern European countries in form of land occupation and communalization represent forms of resistance that enhance social cohesion and collective action in times of need. Specifically, this research examines the role of urban gardens in (i building community resilience and (ii articulating forms of resistance and contestation to development pressure and commodified urban lifestyles. Our research is based on data collected among 27 urban gardening initiatives in Barcelona, Spain, including 13 self-governed community gardens and 14 public gardens. Data were collected from semi-structured interviews with gardeners and with staff from the Barcelona City Council. Our results show mechanisms through which urban gardens can contribute to build resilience by nurturing social and ecological diversity, generating and transmitting local ecological knowledge, and by creating opportunities for collective action and self-organization. We further examine collectively managed gardens as urban commons that emerge as a form of resistance to the privatization of public urban space, and that offer opportunities to experiment with new models of urban lifestyles. We show how gardening initiatives can be seen to represent an emerging form of urban green commons that provides a suitable ground to ‘sow’ resilience and contestation in times of crises and socio-ecological deterioration.

  16. Role of social media and networking in volcanic crises and communication

    2017-01-01

    The growth of social media as a primary and often preferred news source has contributed to the rapid dissemination of information about volcanic eruptions and potential volcanic crises as an eruption begins. Information about volcanic activity comes from a variety of sources: news organisations, emergency management personnel, individuals (both public and official) and volcano monitoring agencies. Once posted, this information is easily shared, increasing the reach to a much broader population than the original audience. The onset and popularity of social media as a vehicle for eruption information dissemination has presented many benefits as well as challenges, and points towards a need for a more unified system for information. This includes volcano observatories using social media as an official channels to distribute activity statements, forecasts and predictions on social media, in addition to the archiving of images and data activity. This chapter looks at two examples of projects that collect / disseminate information regarding volcanic crises and eruptive activity utilizing social media sources. Based on those examples, recommendations are made to volcanic observatories in relation to the use of social media as a two-way communication tool. These recommendations include: using social media as a two-way dialogue to communicate and receive information directly from the public and other sources; stating that the social media account is from an official source; and, posting types of information that the public are seeking such as images, videos and figures.

    2011-06-01

    Full Text Available The strategies for structural-systemic crisis management have generated, to a geographical level, a number of differences between EU countries. These cleavages are the result of differentialmacroeconomic policies. In this context, this article has the aim of achieving a comparative approach between countries of the south, west and east of the EU space. Also our approach is focused on observing the nature of macroeconomic policies and also on identifying a "pattern" associated with a common ideal -type of "rational choice" in the efficient and effective management of systemic crises. This article aims to identify areas of growth and economic stability of a particular model of public policy and political-economic ideology, to set up a mechanism for "economic engineering”. From the methodological point of view, this article uses a quantitativemethodology, derived from mathematical analysis, statistics and stochastic, in order to explain, understand and predict the possible evolution of the systemic crises in the EU countries. The interest lies in the possibility of giving a model of macroeconomic policy for the adjustment of inflationist imbalances, labor market and pricepolicy, and also in regulating the equation of production-consumption.

  18. Confronting ecological futures: global environmental crises in contemporary survival quests for young adults

    Directory of Open Access Journals (Sweden)

    Yvonne Hammer

    2010-01-01

    Full Text Available This paper examines representations of societal concern in the futuristic ecological disaster fictions of three British authors: Julie Bertagna (Exodus; Zenith, Jan Mark (Riding Tycho; Voyager and Marcus Sedgwick Floodland. The depicted refugee journeys in these futuristic worlds speak into a growing global disquiet that surrounds current historic events. Environmental crises that ground the emergent world orders of depicted future societies set the scene in each coming of age frame: each survival quest embeds social and cultural issues recognisable to contemporary audiences in futuristic representations of changed world orders, limited resources, and isolated communities. Authors resist the mythic frame of a traditional quest journey − a call to journey, the engagement with growth through a road of trials and then celebrations in a return to home territory: their conclusions offer limited resolutions, the struggle to survive entrenched as a linear path. Because authors link depictions of the refugee subject with environmental degradation, apocalyptic scenarios that signify the devastating consequences of global environmental crises provide an ecocritical platform from which each author situates a discourse of protest. Interrogating contemporary political positions of ambiguity and denial their novels profile social justice issues experienced by refugee populations in contemporary society.

  19. Linear and nonlinear market correlations: Characterizing financial crises and portfolio optimization

    Pearson correlation and mutual information-based complex networks of the day-to-day returns of U.S. S&P500 stocks between 1985 and 2015 have been constructed to investigate the mutual dependencies of the stocks and their nature. We show that both networks detect qualitative differences especially during (recent) turbulent market periods, thus indicating strongly fluctuating interconnections between the stocks of different companies in changing economic environments. A measure for the strength of nonlinear dependencies is derived using surrogate data and leads to interesting observations during periods of financial market crises. In contrast to the expectation that dependencies reduce mainly to linear correlations during crises, we show that (at least in the 2008 crisis) nonlinear effects are significantly increasing. It turns out that the concept of centrality within a network could potentially be used as some kind of an early warning indicator for abnormal market behavior as we demonstrate with the example of the 2008 subprime mortgage crisis. Finally, we apply a Markowitz mean variance portfolio optimization and integrate the measure of nonlinear dependencies to scale the investment exposure. This leads to significant outperformance as compared to a fully invested portfolio.

    2004-01-01

    Historically, symptoms of Mexican financial crises have been strongly reflected in the dynamics of the Mexican peso to the dollar exchange currency market. Specifically, in the Mexican financial crises during 1990's, the peso suffered significant depreciation processes, which has important impacts in the macro- and micro-economical environment. In this paper, it is shown that the peso depreciation growth was greater than an exponential and that these growth rates are compatible with a spontaneous singularity occurring at a critical time, which signals an abrupt transition to new dynamical conditions. As in the major 1990's financial crisis in 1994-1995, some control actions (e.g., increasing the USA dollar supply) are commonly taken to decelerate the degree of abruptness of peso depreciation. Implications of these control actions on the crisis dynamics are discussed. Interestingly, by means of a simple model, it is demonstrated that the time at which the control actions begin to apply is critical to moderate the adverse effects of the financial crisis.

    2016-12-01

    The growth of social media as a primary and often preferred news source has led to the rapid dissemination of information about volcanic eruptions and potential volcanic crises as they begin, evolve, and end. This information comes from a variety of sources: news organisations, emergency management personnel, individuals (both members of the public and official representatives), and volcano monitoring agencies. Once posted, this information is easily shared, increasing the reach to a much broader population than more traditional forms of media, such as radio and newspapers. The onset and popularity of social media as a vehicle for dissemination of eruption information points toward the need to systematically incorporate social media into the official channels that volcano observatories use to distribute activity statements, forecasts, and images. We explore two examples of projects that collect/disseminate information regarding volcanic crises and eruptive activity via social media sources; the Smithsonian/USGS Weekly Volcanic Activity Report (WVAR), which summarizes new and on-going volcanic activity globally and on a weekly basis, and Eruptions, a blog that discusses eruptions as well as other volcanic topics. Based on these experiences, recommendations are made to volcanic observatories in relation to the use of social media as a communication tool. These recommendations include: using social media as a two-way dialogue to communicate and receive information directly from the public and other sources; stating that the social media account is from an official source; and posting types of information that users want to see such as images, videos, and figures.

    Directory of Open Access Journals (Sweden)

    John Walliss

    2006-01-01

    Full Text Available In this article the author develops some of the points he has made elsewhere regarding the role of what may be termed ‘crises of charismatic authority’ in producing volatility or even violence within marginal apocalyptic religious groups. The last quarter of the twentieth century witnessed several incidents where such groups engaged in violent actions against themselves, others in the outside world, or typically both (among them the Peoples Temple in Guayana in 1978, Branch Davidians in Waco, Texas in 1994, Order of the Solar Temple in Switzerland, Quebec and France in 1997, Aum Shirinkyo, Japan in 1995, Movement for the Restoration of the Ten Commandments of God, Uganda in 2000. This notion of ‘crises of charismatic authority’ has in many ways become a central, recurring theme in the author's analysis of these incidents. While accepting that such crises were typically not sufficient in themselves to have precipitated each of the dramatic denouements the author has examined, he has come to the conclusion that they did play a major role in each; such crises played a much more significant role than that played by external opposition in almost all of the cases the author examined (the case of the Branch Davidians being perhaps the exception that proves the rule. In this article, the author discusses what he means by crises of charismatic authority (an important task in itself due to the diverse understandings of ‘charisma’ found within the literature and presents a comparative analysis of some of the ways in which these crises can occur.

Evidências obtidas a partir de um conjunto de indicadores calculados por país e por região para cada ano entre 1990 e 2004 sugerem que as economias do Leste Asiático eram potencialmente mais vulneráveis em aspectos relacionados ao setor bancário, enquanto as fragilidades das economias latino-americanas concentravam-se nos desequilíbrios fiscais e nas transações correntes do balanço de pagamentos. Por sua vez, estimativas do grau de severidade das crises mostram que, embora atenuadas na crise asiática de 1997-1998, as diferenças regionais persistiam.This article focuses on the sources of vulnerability to currency and financial crises as well as on their degree of severity in Latin American and East Asian economies. Evidence based on a number of indicators reckoned for each country and for each region for every year over the period 1990-2004 suggests that the East Asian economies were potentially more vulnerable to troubles in the banking sector, while Latin American economies' weaknesses seem to be concentrated on fiscal and current account imbalances. Furthermore, the severity crisis indicators point out that there still remained regional contrasts, lessened only during the 1997-1998 Asian crises.

    Using data for 300 stocks listed quoted on the NYSE, we show that commonalities in liquidity within a given portfolio are dependent upon the market capitalization of the stocks that are included in the portfolio. We also show that financial crises have an impact on liquidity co-movements. This impact varies with the market capitalization of the stocks included in the portfolio.

    Full Text Available Este artigo tem como objetivo analisar a tendência da saúde publica universal brasileira no contexto da crise estrutural do capitalismo, articulando os interesses do capital e do Estado, sem que seja possível se referir à uma crise do Estado Moderno. Para tanto, o artigo está organizado em duas partes. A primeira parte busca analisar a natureza da crise, identificando tendências do desenvolvimento do capitalismo, principalmente nas últimas décadas do século XX e na primeira década do século XXI, com destaque para a lei marxiana da queda tendencial da taxa de lucro e a dominância do capital portador de juros. A segunda parte discute os impactos dessa crise ao direito universal da saúde no Brasil, especialmente, a partir dos anos 1990, confirmando as incertezas do financiamento do SUS e o crescente movimento de apropriação do capital sobre os recursos das políticas sociais de direitos, as da seguridade social, especialmente a saúde. Por fim, são apresentadas as considerações finais, incluindo algumas propostas para enfrentar esse quadro de instabilidade e subfinanciamento desse sistema de saúde.

    Full Text Available The actual article is intended to underline the way in which crises and local and regional conflicts nowadays influence the global economic development The dependence of the small states on the actions of the more developed countries, the economic growth accelerated by the scientific-technological developments and the attitude of the geopolitical actors on global context, describe in detail the ideas extracted from the theme of this article. The economic development is necessary, convenient and unavoidable, the main problems appearing when the main raw materials and essential resources for human survival must be insured. The present international relations and the ways in which political-diplomatic differences are solved, support the need of existence and involvement of some organizations and unbiased pacifist forums wherever societies have differences of opinions.

  5. Organizational collaborative capacity in fighting pandemic crises: a literature review from the public management perspective.

    Science.gov (United States)

    Lai, Allen Y

    2012-01-01

    Collaborative capacity serves for organizations as the capacity to collaborate with other network players. Organizational capacity matters as collaboration outcomes usually go beyond single-shot implementation efforts or a single-minded focus on either the vertical dimension of program or the horizontal component. This review article explores organizational collaborative capacities from the perspective of public management, in particular, network theory. By applying the 5 attributes of network theory-interdependence, membership, resources, information, and learning-to the explanation of collaborative capacity in fighting pandemic crises, I argue in some ways organizational collaborative capacity is very much like an organization in its own right. Studying collaborative capacity in the battle against pandemics facilitate our understanding of multisectoral collaboration in technical, political, and institutional dimensions, and greatly advances the richness of capacity vocabulary in pandemic response and preparedness.

  6. When Health Diplomacy Serves Foreign Policy: Use of Soft Power to Quell Conflict and Crises.

    2016-10-01

    Health diplomacy has increasingly become a crucial element in forging political neutrality and conflict resolution and the World Health Organization has strongly encouraged its use. Global turmoil has heightened, especially in the Middle East, and with it, political, religious, and cultural differences have become major reasons to incite crises. The authors cite the example of the human stampede and the deaths of over 2000 pilgrims during the 2015 annual Haj pilgrimage in Mecca. The resulting political conflict between Iran and Saudi Arabia had the potential to escalate into a more severe political and military crisis had it not been for the ministers of health from both countries successfully exercising "soft power" options. Global health security demands critical health diplomacy skills and training for all health providers. (Disaster Med Public Health Preparedness. 2016;page 1 of 4).

  7. [Emotional deprivation and narcissistic regulation--development and treatment of depressive crises in children and adolescents].

    Science.gov (United States)

    du Bois, Reinmar

    2007-01-01

    This paper outlines developmental and treatment issues of depression in childhood and adolescence. Impairment of parental empathy based on emotional disturbances of a parent leads to adaptive reactions as the child is confronted with threats of loss and separation. Hereditary vulnerability as well as insecure attachment patterns and the effects of explicit trauma must be viewed as further facilitating factors. Anxiety in children and--with the advent of adolescence--suicidal behaviour are described as important tools for narcissistic regulation and reconciliation and for mobilising help. Accordingly the last section of the paper is dedicated to therapeutic approaches to adolescent despair, depression, risk taking and suicidal behaviour. Guiding suicidal adolescents out of their crises can be a tightrope walk between attempts to limit life threatening acting-out behaviours, leniency toward the patients' grandiosity along with sensitivity for narcissistic injuries and the building of a viable narcissistic transference.

    Full Text Available Faced with the disorderly way of conceiving life in the current model of political and economic development, which has compromised our common home due to the depredation of all forms of life in the biosphere, and in light of the moral and ethical crisis of our time that has fostered a culture of relativism, disposability and immediacy, this reflection aims to analyze how Pope Francis connects the environmental crisis with the ethical and moral crisis in his Laudato si’ encyclical. Pope Francis believes that we do not live in a time of several crises but rather one complex crisis which is both social and environmental which is the external manifestation of the ethical and moral, cultural and spiritual crisis of humanity. The cry for help of the Earth is inseparable from that of the poor, so only an integral ecology can help heal fundamental human relationships.

    Full Text Available This paper tries to further investigate the factors behind a financial crisis. By using a large sample of countries in the period 1981 to 1999, it intends to apply two methods coming from the Artificial Intelligence (Rough Sets theory and C4.5 algorithm and analyze the role of a set of macroeconomic and financial variables in explaining banking crises. These variables are both quantitative and qualitative. These methods do not require variables or data used to satisfy any assumptions. Statistical methods traditionally employed call for the explicative variables to satisfy statistical assumptions which is quite difficult to happen. This fact complicates the analysis. We obtained good results based on the classification accuracies (80% of correctly classified countries from an independent sample, which proves the suitability of both methods.

We lack the ability to keep the peace (silence for to counter the excesses of the financial markets. Without this ability, the global economy is exposed to the collapse. Financial capital enjoys a privileged position. He is more mobile than other factors of production and even more mobile than direct investment. Yet crises must be overcome.

    2005-01-01

    We investigate the mechanism for boundary crises in the quasiperiodically forced logistic map which is a representative model for quasiperiodically forced period-doubling systems. For small quasiperiodic forcing ε, a chaotic attractor disappears suddenly via a 'standard' boundary crisis when it collides with the smooth unstable torus. However, when passing a threshold value of ε, a basin boundary metamorphosis occurs, and then the smooth unstable torus is no longer accessible from the interior of the basin of the attractor. For this case, using the rational approximations to the quasiperiodic forcing, it is shown that a nonchaotic attractor (smooth torus or strange nonchaotic attractor) as well as a chaotic attractor is destroyed abruptly through a new type of boundary crisis when it collides with an invariant 'ring-shaped' unstable set which has no counterpart in the unforced case

    Full Text Available This paper outlines a long-term policy and institutional framework for reducing the intensity of recessions, debt crises and financial instabilities, especially for the Core nations and areas that bore the brunt of the anomalies during 2008-2013. We argue that institutional changes need to be systemic, amounting to the construction of a new social structure of accumulation (SSA or mode of regulation (MOR, which we call an SSA of embedded communitarian liberalism. Five institutional spheres are introduced which are in need of systemic change, due to the entrenched contradictions and problems which the current set of institutions generate. These involve firstly institutions within the world-system of finance and production; secondly relating to finance versus industry; thirdly capital versus labor; fourthly state systems of production; and fifthly the interlinking of state, community and ecology.

  14. Teoria da Regulação e Crise do Fordismo

    Ana Carolina Bottega de Lima

    2017-11-01

    Full Text Available This paper deals with the crisis of Fordism, based on the theory of crises elaborated by Regulation Theory, also addressing the origins and foundations of this school. In the context of the end of the years of vigorous capitalist growth in the 1970s, the Regulation School emerged as a new stream of economic thought, building an analysis of the process and dynamics of capitalist accumulation. In particular, this school was consolidated in the economic theory from the elaboration of its theory of crisis. Thus, it provided alternative interpretations of the 1970s’ crisis, countering the explanations of traditional economic theory, by considering crisis as an endogenous phenomenon. Starting from this proposition to understand the crisis of Fordism, a theory with broad explanatory potential was found, from whose study a broader understanding of economic phenomena can be obtained.

    Full Text Available A integração comercial e financeira global fortaleceu a classe capitalista em relação ao proletariado em cada país ao permitir às transnacionais deslocar suas empresas para países em que o custo da mão de obra é menor. A crise colheu a América Latina pela fuga das divisas fortes, extinção do crédito externo e queda das exportações, das inversões estrangeiras e das remessas dos emigrados. A crise se generaliza com as demissões em massa, a difusão do pânico que faz o crédito encolher, derrubando as vendas de bens de maior valor e os investimentos. Os governos do Primeiro Mundo trataram de resgatar os seus bancos falidos, comprando parte do seu capital ou sua totalidade com recursos do Tesouro. No Brasil, o governo faz que os bancos públicos estendam o crédito aos setores abandonados pelos bancos privados e baixem os juros que cobram. Os governos latino-americanos estimulam o mercado interno a absorver a produção que não enontra mais compradores no exterior mediante redistribuição da renda e aumento do investimento público. Nos últimos seis anos, os emergentes cresceram 50%, enquanto os industrializados cresceram apenas 10%, o que ampliou o número de nações cuja coordenação é indispensável para que a crise mundial possa ser domada do G-7 para o G-20. Uma das lições da crise é que, em lugar da globalização financeira, o povo de cada país deve ter o direito de decidir como seu excedente social deve ser administrado. A guarda do dinheiro do público e o seu empréstimo a investidores e consumidores devem ser reservados ao poder público e a entidades associativas sem fins de lucro.Global commercial and financial integration has strengthened the capitalist class in comparison with the proletariat around the globe as it permitted multinationals to relocate their companies to countries in which the cost of the labor force was lower.

The most important at the «Childless couple stage» is an attitude to expression of jealousy. If the family endures the crisis, spouses have an active negative reaction on an expression of jealousy. At the stage «Family with young children» at the forefront there are money disagreements, which prove an existence of family crisis from our point of view.   Practical implications are in the area of practical and scientific activity of family psychologists.DOI: http://dx.doi.org/10.12731/2218-7405-2013-7-14

O referencial teórico está apoiado nas Teorias Keynesiana, Neoinstitucionalista e das Finanças Públicas. Trata-se de um artigo bibliográfico, descritivo e qualitativo, cujas discussões estão baseadas nas projeções contidas nos relatórios das principais instituições multilaterais e nacionais brasileiras, em especial nas variáveis econômicas mais relevantes como o crescimento da economia mundial, do comportamento do nível de emprego e da inflação. Os resultados das discussões, a partir das análises dos documentos citados, evidenciam que a crise econômica mundial continua impactando de forma preocupante na maioria dos países, em especial, dos países membros da Zona do Euro e Estados Unidos, e que o desempenho da economia brasileira deverá crescer num ritmo menor nos próximos anos. Essas constatações permite concluir que se faz necessário a definição de um diagnóstico consistente para o Brasil, que permita uma mudança estrutural no potencial de expansão da economia do país, em especial, preparando de forma mais adequada o seu ambiente macro e microeconômico.

    Freund, M.T.; Wise, J.A.; Ulibarri, C.A.; Shaw, B.R.; Seely, H.E.; Roop, J.M.

    1994-11-01

    This paper addresses US energy security in the post-Cold War era for a conference on energy security jointly sponsored by the Department of Energy and the National Defense University. It examines the evolving nature of energy security based on analysis of past crisis-inducing events and-discusses potentially important geopolitical, environmental, regulatory, and economic developments during the next twenty-five years. The paper steps beyond the traditional economic focus of energy security issues to examine the interplay between fundamental economic and technical drivers on the one hand, and political, environmental, and perceptual phenomena, on the other hand, that can combine to create crises where none were expected. The paper expands on the premise that the recent demise of the Soviet Union and other changing world conditions have created a new set of energy dynamics, and that it is imperative that the United States revise its energy security perspective accordingly. It proceeds by reviewing key factors that comprise the concepts of ``energy security`` and ``energy crisis`` and how they may fit into the new world energy security equation. The study also presents a series of crisis scenarios that could develop during the next twenty-five years, paying particular attention to mechanisms and linked crisis causes and responses. It concludes with a discussion of factors that may serve to warn analysts and decision makers of impending future crises conditions. The crisis scenarios contained in this report should be viewed only as a representative sample of the types of situations that could occur. They serve to illustrate the variety of factors that can coalesce to produce a ``crisis.``

    Full Text Available Com a crescente globalização, os mercados financeiros do mundo todo passaram a apresentar maior integração. Tal relacionamento entre mercados possui como implicação um termo que vem atraindo a atenção de profissionais e acadêmicos, a transmissão de volatilidade. Dessa forma, o presente trabalho tem como escopo analisar a transmissão internacional de volatilidade no mercado brasileiro. Para tanto, é utilizado um modelo Garch multivariado com parametrização BEKK. Com base nesse modelo, são estimados os relacionamentos bivariados entre o mercado brasileiro, representado pelo índice Ibovespa, e os mercados americano, argentino, mexicano e chinês, utilizando-se de índices representativos de 4 de janeiro de 2000 até 31 de março de 2010, totalizando 2667 cotações. A amostra foi dividida em três partes, representando os períodos anteriores, durante e posteriores à crise do subprime de 2007/2008. Os resultados obtidos permitem concluir que, durante a crise de 2008, de forma geral, houve mudança na direção da transmissão de volatilidade entre o mercado brasileiro e os demais estudados, de forma ao Brasil passar a exercer maior influência na volatilidade condicional desses, por ter sofrido menores consequências com a crise financeira. Além disso, após o período de turbulência causado pela crise de 2008, o relacionamento da volatilidade entre o mercado brasileiro com os demais passou a ser menos assimétrico do que no período anterior a crise.

    To summarize recent data on classification systems, cause, risk factors, severity prediction, nutrition, and drug treatment of acute pancreatitis. Comparison of the Revised Atlanta Classification and Determinant Based Classification has shown heterogeneous results. Simvastatin has a protective effect against acute pancreatitis. Young black male, alcohol, smoldering symptoms, and subsequent diagnosis of chronic pancreatitis are risk factors associated with readmissions after acute pancreatitis. A reliable clinical or laboratory marker or a scoring system to predict severity is lacking. The PYTHON trial has shown that oral feeding with on demand nasoenteric tube feeding after 72 h is as good as nasoenteric tube feeding within 24 h in preventing infections in predicted severe acute pancreatitis. Male sex, multiple organ failure, extent of pancreatic necrosis, and heterogeneous collection are factors associated with failure of percutaneous drainage of pancreatic collections. The newly proposed classification systems of acute pancreatitis need to be evaluated more critically. New biomarkers are needed for severity prediction. Further well designed studies are required to assess the type of enteral nutritional formulations for acute pancreatitis. The optimal minimally invasive method or combination to debride the necrotic collections is evolving. There is a great need for a drug to treat the disease early on to prevent morbidity and mortality.

    Full Text Available Abstract: In this article we examined the impact of economic crises in the years 2008/2009 on the logistics industry in old member states EU-15 and the new EU member states. The emergence of the economic crisis in 2008/2009 when the states of the old members of EU-15 and new EU member states were the first time subjected to the effects of the crisis inside the single entity-the European Union. Research question: The basic research question is: Were implications of economic crises in the years 2008/2009 in logistics industry in heterogenic states of European Union; old member states EU-15 and the new EU member states different? Purpose:We wanted to determine how the logistics companys in old member States EU (15 and in the new EU member states adapt to the new circumstances caused by economic crises in the years 2008/2009. Method: Economic crises are complex multifunctional phenomenon. Analysing complexity of the changes of the state of economic system need to supplement the pure scientific approach with other types of research work, more holistic approach, which is commonly used in Comparative economics. In this article we combine both. In empirical part we used appropriate parametric and non-parametric tests of differences between old and new member states of the European Union.

    Sickle cell crisis, or vaso-occlusive crisis (VOC), is a major cause of hospitalizations for adults and children with sickle cell disease, and is associated with increased morbidity and mortality. Despite prompt pharmacological treatment and multimodal pain management, acute pain during a VOC is often not adequately controlled in the pediatric population. We placed a continuous popliteal sciatic nerve block under ultrasound guidance in a pediatric patient for localized refractory pain during a VOC, resulting in improved pain control with preserved sensorimotor function.

    Synopsis Recent studies suggest that sickle cell disease is a hypercoagulable state contributing to the vaso-occlusive events in microcirculation resulting in acute and chronic sickle cell related organ damage. In this article, we will review the existing evidence for contribution of hemostatic system perturbation to sickle cell disease pathophysiology. We will also review the data showing increased risk of thromboembolic events, particularly newer information on the incidence of VTE. Finally, the potential role of platelet inhibitors and anticoagulants in SCD will be briefly reviewed. PMID:24589271

    Crisis and emergency psychiatric services are an integral part of the healthcare system, yet there are no standardized measures for programs providing these services. We developed the Crisis Reliability Indicators Supporting Emergency Services (CRISES) framework to create measures that inform internal performance improvement initiatives and allow comparison across programs. The framework consists of two components-the CRISES domains (timely, safe, accessible, least-restrictive, effective, consumer/family centered, and partnership) and the measures supporting each domain. The CRISES framework provides a foundation for development of standardized measures for the crisis field. This will become increasingly important as pay-for-performance initiatives expand with healthcare reform.

  7. Um olhar sistêmico sobre a crise norte-americana

    CHRISTIAN CARVALHO GANZERT

    Full Text Available RESUMO No contexto contemporâneo, a economia global pode ser descrita como um sistema baseado em agentes que, quando associados, manifestam seus próprios meios e fins. A crise das hipotecas subprime nos Estados Unidos é um bom exemplo das implicações desse tipo de relacionamento. Ela está diretamente relacionada a poderosos laços de realimentação, compostos por uma série de variáveis que amplificaram o fato de as famílias americanas terem se endividado em ritmo maior do que a sua distribuição de riqueza, prejudicada pela externalização da produção. Há atualmente uma nova estrutura na economia internacional, em que as ex-nações subdesenvolvidas estão mais bem posicionadas no cenário macroeconômico e têm maior poder do que antes - uma consequência do necessário rearranjo sistêmico. Diante dessa complexa dinâmica, a função de inteligência que deveria controlar e garantir a estabilidade sistêmica falhou em perceber a dinâmica e os impactos da nova cultura atrelada ao comportamento do capital contemporâneo, para evitar a perda da hegemonia. Observando-se ex post facto, por meio de um enfoque sistêmico, a crise econômica americana pode ser definida como tendo suas raízes nas premissas de todo o arcabouço cultural da globalização que acabou por conduzir à externalização da produção. Assim, o contexto sistêmico desta análise aponta que a cultura, como importante gerador e amplificador, deve ser o principal foco dos intentos de análise do atual contexto socioeconômico global.

    Splenic dysfunction is a major feature of sickle cell disease (SCD) and can manifest as acute splenic sequestration crisis (ASSC), which is the earliest life-threatening complication seen in patients with SCD. Aplastic crisis is another potentially deadly complication of sickle cell disease that develops when erythrocyte production temporarily drops. Infection with parvovirus B-19 frequently causes aplastic crises. These two complications are known to be mutually exclusive due to their classic presentation signs and symptoms but there have been few cases where a patient can have concomitant presentation of both phenomena, which can result in a fatal outcome. These few cases force us to rethink the etiology and subsequent management guidelines of these complications. We present to you a case of an unfortunate 23-year-old female who had both complications occurring at the same time, resulting in death.

    Full Text Available This explorative study presents an empirical examination of the connection between motivation and the measures individuals take to prevent everyday accidents and prepare for crises. Positional factors (age and gender and situational factors (education, size of locality, and household composition are included because the literature highlights their importance. The study used data gathered in a 2010/2011 poll of randomly selected Swedish residents aged 16–75 (N = 2000; 44.8% response rate. A factor analysis reduced the theoretical model for situational motivation (Guay, Vallerand, & Blanchard, 2000 from four to two dimensions: motivation and amotivation. Subsequent regression analyses statistically confirmed the connection between motivation or amotivation and the extent to which individuals pursue preventative and preparedness measures, even when accounting for positional and situational factors. These findings underscore the need for continued studies of individuals’ incentives to prevent accidents and prepare for crises and for the study of the nuances of (situational motivation and preventive/preparedness measures.

    2017-09-01

    Full Text Available Heavy damages might be inflicted upon national infrastructure due to a variety of disasters caused by natural events or human activities. One example of such vital infrastructure at risk is the water supply system. At the time of crises, the water supply system is expected to continue supplying water to citizens, or the crisis will be augmented. This warrants the potential threats and their effects on the system to be identified and evaluated in an attempt to determine the vulnerable systems and sites toward proper solutions. In this study, the assets and the associated threats of the water supply are identified followed by a vulnerability analysis. The RAMCAP method is then employed to determine values for the risks associated with each of the assets including dams, water storage systems, pumping stations, treatment plants, water wells, and building units. Methods are proposed to reduce these risks before a crisis occurs. In addition, basic threats due to air-missile and Cyber attacks are also considered.

  2. Cross-border Portfolio Investment Networks and Indicators for Financial Crises

    2014-02-01

    Cross-border equity and long-term debt securities portfolio investment networks are analysed from 2002 to 2012, covering the 2008 global financial crisis. They serve as network-proxies for measuring the robustness of the global financial system and the interdependence of financial markets, respectively. Two early-warning indicators for financial crises are identified: First, the algebraic connectivity of the equity securities network, as a measure for structural robustness, drops close to zero already in 2005, while there is an over-representation of high-degree off-shore financial centres among the countries most-related to this observation, suggesting an investigation of such nodes with respect to the structural stability of the global financial system. Second, using a phenomenological model, the edge density of the debt securities network is found to describe, and even forecast, the proliferation of several over-the-counter-traded financial derivatives, most prominently credit default swaps, enabling one to detect potentially dangerous levels of market interdependence and systemic risk.

    Emergency department leaders at DCH Regional Medical Center in Tuscaloosa, AL, and Cullman Regional Medical Center in Cullman, AL, credit their regular practice drills with helping them deal with unprecedented demand when deadly tornadoes swept through the South this past April. Both facilities used the hospital instant command structure (HICS) to mobilize the resources needed to care for the surge in patients, and say the approach worked well in helping them meet the needs of their communities. However, the crises also showcased opportunities for improvement. The ED at DCH Regional Medical Center saw more than 600 patients on the day of the storm, a three-fold increase in the hospital's typical volume. CRMC treated 99 patients in the seven hours immediately following the storm when it usually treats 114 patients per day. In addition to a big surge in patients, both hospitals dealt with power outages that limited access to some services such as radiology. Triage proved particularly challenging at DCH Regional Medical Center, as patients flowed into the hospital from numerous access points. The hospital plans to assign coordinators to each area of the hospital to better manage the influx in the future. When reviewing emergency operations plans, Joint Commission reviewers often find deficiencies in hazard vulnerability analyses as well as the processes used to determine the emergency credentials of licensed independent practitioners.

    2017-04-01

    Using sampled historical daily gold market data from 07-03-1985 to 06-01-2015, and building on a related work by Bentes (2016), this paper examines the presence of long-range dependence (LRD) in the world's gold market returns and volatility, accounting for structural breaks. The sampled gold market data was divided into subsamples based on four global crises: the September 1992 collapse of the European Exchange Rate Mechanism (ERM), the Asian financial crisis of mid-1997, the Subprime meltdown of 2007, and the recent European sovereign debt crisis, which hit the world's market with varying effects. LRD test was carried-out on the full-sample and subsample periods using three semiparametric methods-before and after adjusting for structural breaks. The results show insignificant evidence of LRD in gold returns. However, very diminutive evidence is found for periods characterized by financial/economic shocks, with no significant detections for post-shock periods. Collectively, this is indicative that the gold market is less speculative, and hence could be somehow less risky for hedging and portfolio diversification.

    Deficiencies in non-technical skills (NTS) have been increasingly implicated in avoidable operating theatre errors. Accordingly, this study sought to characterize the impact of surgeon and anaesthetist non-technical skills on time to crisis resolution in a simulated operating theatre. Non-technical skills were assessed during 26 simulated crises (haemorrhage and airway emergency) performed by surgical teams. Teams consisted of surgeons, anaesthetists and nurses. Behaviour was assessed by four trained raters using the Non-Technical Skills for Surgeons (NOTSS) and Anaesthetists' Non-Technical Skills (ANTS) rating scales before and during the crisis phase of each scenario. The primary endpoint was time to crisis resolution; secondary endpoints included NTS scores before and during the crisis. A cross-classified linear mixed-effects model was used for the final analysis. Thirteen different surgical teams were assessed. Higher NTS ratings resulted in significantly faster crisis resolution. For anaesthetists, every 1-point increase in ANTS score was associated with a decrease of 53·50 (95 per cent c.i. 31·13 to 75·87) s in time to crisis resolution (P technical skills scores were lower during the crisis phase of the scenarios than those measured before the crisis for both surgeons and anaesthetists. A higher level of NTS of surgeons and anaesthetists led to quicker crisis resolution in a simulated operating theatre environment. © 2017 BJS Society Ltd Published by John Wiley & Sons Ltd.

    2015-12-01

    Full Text Available The results of the single-equation cointegration tests indicate that patterns of cointegration in the two main and four sub-periods are not homogeneous. Two key findings emerge from the study. First, fewer stock markets cointegrated with S&P 500 during the crisis period than they did during the pre-crisis. In other words, as the 2008 financial crisis deepened, S&P 500 and G-20 stock indices moved towards less cointegration. The decreasing number of cointegrating relationships implies that the U.S. stock markets and other G-20 markets have experienced different driving forces since the start of the U.S. crisis. Second, among those markets that are cointegrated with S&P 500, they happened to be deeply affected by S&P and the shocks emerging from it. The 2007–2009 financial crises can be considered a structural break in the long-run relationship and may have resulted from effective joint intervention/responses taken by members of G-20 nations.

  10. From famine to food crisis: what history can teach us about local and global subsistence crises.

    Vanhaute, Eric

    2011-01-01

    The number of famine prone regions in the world has been shrinking for centuries. It is currently mainly limited to sub-Saharan Africa. Yet the impact of endemic hunger has not declined and the early twenty-first century seems to be faced with a new threat: global subsistence crises. In this essay I question the concepts of famine and food crisis from different analytical angles: historical and contemporary famine research, food regime theory, and peasant studies. I will argue that only a more integrated historical framework of analysis can surpass dualistic interpretations grounded in Eurocentric modernization paradigms. This article successively debates historical and contemporary famine research, the contemporary food regime and the new global food crisis, the lessons from Europe's 'grand escape' from hunger, and the peasantry and 'depeasantization' as central analytical concepts. Dualistic histories of food and famine have been dominating developmentalist stories for too long. This essay shows how a blending of historical and contemporary famine research, food regime theory and new peasant studies can foster a more integrated perspective.

  11. The Relevance of Employee-Related Ratios for Early Detection of Corporate Crises

    2014-12-01

    Full Text Available The purpose of this study was to analyse whether employee-related ratios derived from accounts have incremental predictive power for the early detection of corporate crises and bankruptcies. Based on the literature reviewed, it can be seen that not much attention has been drawn to this task, indicating that further research is justified. For empirical research purposes, a database of Austrian companies was used for the time period 2003 to 2005 in order to develop multivariate linear discriminant functions for the classification of companies into the two states; bankrupt and non-bankrupt, and to detect the contribution of employee-related ratios in explaining why firms fail. Several ratios from prior research were used as potential predictors. In addition, other separate ratios were analysed, including employee-related figures. The results of the study show that while employee-related ratios cannot contribute to an improvement in the classification performance of prediction models, signs of these ratios within the discriminant functions did show the expected directions. Efficient usage of employees seems to play an important role in decreasing the probability of insolvency. Additionally, two employee-related ratios were found which can be used as proxies for the size of the firm. This had not been identified in prior studies for this factor.

    Health monitoring of world economy is an important issue, especially in a time of profound economic difficulty world-wide. The most important aspect of health monitoring is to accurately predict economic downturns. To gain insights into how economic crises develop, we present two metrics, positive and negative income entropy and distribution analysis, to analyze the collective "spatial" and temporal dynamics of companies in nine sectors of the world economy over a 19 year period from 1990-2008. These metrics provide accurate predictive skill with a very low false-positive rate in predicting downturns. The new metrics also provide evidence of phase transition-like behavior prior to the onset of recessions. Such a transition occurs when negative pretax incomes prior to or during economic recessions transition from a thin-tailed exponential distribution to the higher entropy Pareto distribution, and develop even heavier tails than those of the positive pretax incomes. These features propagate from the crisis initiating sector of the economy to other sectors.

    Review of late Holocene paleoenvironmental and cultural sequences from four regions of western North America show striking correlations between drought and changes in subsistence, population, exchange, health, and interpersonal violence during the Medieval Climatic Anomaly (A.D. 800-1350). While ultimate causality is difficult to identify in the archaeological record, synchrony of the environmental and cultural changes and the negative character of many human responses--increased interpersonal violence, deterioration of long-distance exchange relationships, and regional abandonments--suggest widespread demographic crises caused by decreased environmental productivity. The medieval droughts occurred at a unique juncture in the demographic history of western North America when unusually large populations of both hunter-gathers and agriculturalists had evolved highly intensified economies that put them in unprecedented ecological jeopardy. Long-term patterns in the archaeological record are inconsistent with the predicted outcomes of simple adaptation or continuous economic intensification, suggesting that in this instance environmental dynamics played a major role in cultural transformations across a wide expanse of western North America among groups with diverse subsistence strategies. These events suggest that environment should not be overlooked as a potential cause of prehistoric culture change.

    Full Text Available Social media (SoMe platforms provide potentially important information for news journalists during everyday work and in crisis-related contexts. The aims of this study were (a to map central journalistic challenges and emerging practices related to using SoMe for collecting and validating newsworthy content; and (b to investigate how practices may contribute to a user-friendly design of a web-based SoMe content validation toolset. Interviews were carried out with 22 journalists from three European countries. Information about journalistic work tasks was also collected during a crisis training scenario (N = 5. Results showed that participants experienced challenges with filtering and estimating trustworthiness of SoMe content. These challenges were especially due to the vast overall amount of information, and the need to monitor several platforms simultaneously. To support improved situational awareness in journalistic work during crises, a user-friendly tool should provide content search results representing several media formats and gathered from a diversity of platforms, presented in easy-to-approach visualizations. The final decision-making about content and source trustworthiness should, however, remain as a manual journalistic task, as the sample would not trust an automated estimation based on tool algorithms.

  15. Impact of Economic Conditions and Crises on Mortality and its Predictability.

    Bohk, Christina; Rau, Roland

    To investigate how economic conditions and crises affect mortality and its predictability in industrialized countries, we review the related literature, and we forecast mortality developments in Spain, Hungary, and Russia-three countries which have recently undergone major transformation processes following the introduction of radical economic and political reforms. The results of our retrospective mortality forecasts from 1991 to 2009 suggest that our model can capture major changes in long-term mortality trends, and that the forecast errors it generates are usually smaller than those of other well-accepted models, like the Lee-Carter model and its coherent variant. This is because our approach is capable of modeling (1) dynamic shifts in survival improvements from younger to older ages over time, as well as (2) substantial changes in long-term trends by optionally complementing the extrapolated mortality trends in a country of interest with those of selected reference countries. However, the forecasting performance of our model is limited (like that of every model): e.g., if mortality becomes extremely volatile-as was the case in Russia after the dissolution of the Soviet Union-generating a precise forecast will depend more on luck than on methodology and expert judgment. In general, we conclude that, on their own, recent economic changes appear to have minor effects on life expectancy in industrialized countries, but that the effects of these changes are greater if they occur in conjunction with other major social and political changes.

    Full Text Available The Republic of Turkey in the year of 2015 has gone through the period of critical transformation of its foreign and domestic policies. The main reason for this transformation is the inability of the Justice and Development Party to reach its goals to draft the new constitution and vest the president of the country with new powers. Nevertheless, the authors believe that there are also historic and demographic reasons for this transformation that have been developing for several decades. The basis of this transformation is the destructive foreign policy course pursued by the ruling elites aimed at fomenting crises inside and outside Turkey. The most tangible signs of that are the resumption of hostilities between the Turkish army and PKK and also regular shillings of the positions of Syrian Kurds by Turkish artillery. According to the authorities of Turkey such policy is likely to force the Turkish society and foreign partners to make concessions and give the Justice and Development Party the right to reform the country in its own way. However, such policy also increases the possibility that some internal and external actors will try to make everything possible to overthrow the ruling regime one way or another.

Firstly, political communication and news coverage are discussed, based on the assumption that the commoditisation of the goals of media and information companies has resulted in changes in the balance between the political and media fields. Within this perspective, attention is devoted to the consequences of these changes in Western democracies, taking into consideration not only certain aspects that tend to subvert underlying principles of representative democracy, but also the emergence of new social movements craving greater democratic participation in the public sphere. In addition, this study examines the concepts of crisis and political corruption, seeking to identify the historical and cultural elements that correlate the two phenomena in Western democracies, especially in Portugal. Finally, it addresses the processes of exposing corruption phenomena and their legal implications, as well as the principles of transparency of information and the consequences upon democracy.

Paulo e Estado de S. Paulo, no primeiro semestre de 2017, encontrar a manifestação de uma voz autoral que assine a voz coletiva no que tange a crise brasileira. Percebe-se, nesta leitura cultural, que é no Jornalismo de opinião que a imaginação criadora perante o caos alimenta quebras da razão analítica aprisionada pela esfera conceitual dada. O toque ensaístico se manifesta contrário, reticente, pluralista perante as afirmações/certezas estabelecidas. Conclui-se com uma proposta: o estímulo à reportagem-ensaio. Nela, o repórter que ousa a observação-experiência ensaia a compreensão sutil inspirada na responsabilidade ética, na qualificação técnica e na criatividade estética, permitindo romper com os reducionismos vigentes.

    Tourism is important to the Jamaican economy accounting for approximately 25% of the gross domestic product. Health problems in tourists could have significant impact on the health of the local population, the scarce health service resources, and the tourist industry. This study was conducted to identify health problems most commonly occurring in tourists visiting Jamaica and examine how these problems are managed. Records of health problems occurring in tourists who visited principal tourist areas on the north coast from June 1998 to June 2002 were reviewed for the type of illness and how the problem was handled. The data were analyzed using Epi-Info software (Centers for Disease Control and Prevention, Atlanta, GA) and Statistical Analysis System software (SAS Institute, Cary, NC). Accidents were the most common health crises reported by tourists. Gastrointestinal, respiratory, and cardiovascular problems occurred less frequently. Those less than 40 years of age more frequently reported accidents or injury, gastrointestinal problems, and drug abuse, whereas respiratory and cardiovascular problems were more common among those above 40 years of age. Cardiovascular problems, drug abuse, and death were more common in men than in women. Hotel nurses handled most of the cases and were more likely to refer patients to private physicians or hospitals than to public hospitals (p Medical insurance covered the costs for 11% of tourists, and 75% paid out of pocket. The information provided by this study can be used to implement changes to reduce health problems in tourists and improve emergency health services in tourist areas.

    Full Text Available This paper shows the main results of a research activity conducted in the South – East region of Romania during November 2009, over 117 small and medium-sized enterprises. The results help to better explain some of the social problems that have been generated in the region as a snow ball effect, due to the economic and financial crisis. The research has revealed the following:The majority of the employees of the companies that were interviewed do not participate in training courses related to project management and personal development. However, company administrators consider that such courses are useful to increase competitiveness in times of economic and financial crises. Personnel under 40 years of age suffer from a lack of professional training and dedication to job requirements. Companies have expressed an interest in accessing European Union funding. However, they do not have complete information that would allow them to start a project and finalize it. This lack of information is mainly due to lack of access to specialists who would write the projects and submit them. The majority of entrepreneurs consider they cannot write the projects themselves but on the other hand they do not have access to consulting companies or other organizations that could help them. Their main information source is the mass-media.As a result, companies have adjusted to the effects of the economic crisis, diminishing their activity and laying off people, decreasing the running expenses and stopping investing in their development.

    Full Text Available In connection with the fi nancial and subsequent economic crisis, the role of non-fi nancial corporations is often discussed and the causes and eff ects of the crisis are analysed. Viewing two critical periods of economic development in the Czech Republic – the first in 1997–1998, and the second in 2009–2010 – we can see that non-financial corporations generated a high level of net borrowing in the fi rst instance and, on the contrary, a high level of net lending in the second instance. Regardless of the diff erent causes of the crises in the abovementioned periods, a natural question arises: what kind of transformation took place in the economic behaviourof non-fi nancial corporations between 1998 and 2008? Consequently, what was the source of their overall (and in a time of crisis, surprising profi t in the crisis years of 2009 and 2010. When analysing the economic behaviour of the non-fi nancial corporations sector in the Czech Republic we will, naturally, base our considerations on the data from national accounts of the Czech Republic as published by the Czech Statistical Office and will also utilise the usual relative indices immediately implied by the national account ones, as well as indices whose construction is closer to the evaluation usual in corporate practice.

    Full Text Available Health monitoring of world economy is an important issue, especially in a time of profound economic difficulty world-wide. The most important aspect of health monitoring is to accurately predict economic downturns. To gain insights into how economic crises develop, we present two metrics, positive and negative income entropy and distribution analysis, to analyze the collective "spatial" and temporal dynamics of companies in nine sectors of the world economy over a 19 year period from 1990-2008. These metrics provide accurate predictive skill with a very low false-positive rate in predicting downturns. The new metrics also provide evidence of phase transition-like behavior prior to the onset of recessions. Such a transition occurs when negative pretax incomes prior to or during economic recessions transition from a thin-tailed exponential distribution to the higher entropy Pareto distribution, and develop even heavier tails than those of the positive pretax incomes. These features propagate from the crisis initiating sector of the economy to other sectors.

    Full Text Available After ten years of the global financial crises, which peak in Romania was 2009, the negative impact on exports and imports of Romania are still in place for some Romanian counties. The scale of the impact highlights the strong connections between the national economy and the economy of the other EU countries, which have suffered during the crisis because of falling demand for imports from Romania. The good export recovery is not a favorable thing for those counties who focused theirs exports on primary products, products based on natural resources and low-technology products. These exports lead to the decrease in foreign exchange earnings and implicitly the potential of endogenous growth at the county level, mainly due to deteriorating terms of trade. The paper is focused on Romanian exports recovery analysis, taking into account the impact of world financial crisis, which started in Romania in 2009. A special attention is paid to the recovery of exports at the regional level and to the importance of the structural changes of Romanian export, occurred in 2017 compared to 2008. Also, in this article are analyzed the concentration of exports at county level, the main partners on export, the share of the first 10 partners and evolution of export per capita at the counties level. The trade balance is used to classify the counties in: net exporters (export>import and net importers (import>export.

    Full Text Available The Ebola crises that crippled West Africa from December 2013 onwards is a watershed moment in the history of those nations. The crises profoundly impacted the regions inadequate healthcare, obstructed the potential for socioeconomic development, and challenged long held traditional and religious beliefs. As Ebola began to take its toll by depleting human life, the world could not stand idly by and observe as poor post-war nations were overwhelmed by a colossal health catastrophe. By the time Ebola was contained, this obnoxious monster had taken an estimated 11,300 lives in the three worst affected countries in the region. But while medical practitioners were at the forefront of the battle, healing evangelists drawing inspiration from their understanding of Scripture, African culture and Charismatic spirituality, also provided responses that proved essential in the fight against Ebola. This article reviews the responses proffered by healing evangelists and discuss how the overall Charismatic spirituality inspired hope in the midst of the Ebola crises in Sierra Leone.

    Full Text Available A preocupação com o futuro da economia brasileira já chegou aos poetas e às revistas internacionais. Os efeitos da crise do subprime fazem parte dessa preocupação. Alguns desafios, como a internacionalização das empresas brasileiras, a atualização tecnológica da produção e as expectativas de consumo no País ganharam destaque nesse processo. A reunião do G-20, no entanto, mostrou que há diferentes métodos de lidar com a crise, preservando-se a maior influência do modo norte-americano de “fazer negócio”. A inserção brasileira na economia internacional, porém, acompanha mais o novo perfil das economias emergentes, que se desenvolve independentemente da crise. Nesse caminho, a maior dificuldade para a inserção internacional eficiente do Brasil, com manutenção da mobilidade social e da tendência de alta no consumo, continua a ser a frágil relaçãointerna entre educação e competitividade.

    Full Text Available This paper quantitatively analyzes the economic resilience of resource-based cities (RBCs in Northeast China in terms of resistance and recoverability during two economic crises: the Asian financial crisis and the global financial crisis. Moreover, it analyzes the main factors that affected regional resilience. There are three main findings. First, the RBCs in general demonstrated poor resistance during both recessions, but there were variations among the different types of RBCs. Petroleum and metal cities demonstrated the most resistance, whereas coal cities performed the worst. Second, the influential factors affecting economic resilience varied across the two economic cycles, but location advantage, research and development (R and D intensity, foreign trade dependence ratio, and supporting policies had positive effects on resilience during both economic cycles, while the proportion of employed persons in resource industries had a negative effect. Industrial diversity had a weak and ambiguous effect on resilience. Third, the secondary industry was more resilient during the Asian financial crisis, but the tertiary industry was more resilient during the global financial crisis. This shift may be attributed to both the nature of the crises and the strength of the sectors at the time of the crises.

    Although the successful pursuit of long-term goals constitutes an essential prerequisite to personal development, health, and well-being, little research has been devoted to the understanding of its underlying neural processes. A critical phase in the pursuit of long-term goals is defined as an action crisis, conceptualized as the intra-psychic conflict between further goal pursuit and disengagement from the goal. In the present research, we applied an interdisciplinary (cognitive and neural) approach to the analysis of processes underlying the experience of an action crisis. In Study 1, a longitudinal field study, action crises in personal goals gave rise to an increased and unbiased (re)evaluation of the costs and benefits (i.e., rewards) of the goal. Study 2 was a magnetic resonance imaging study examining resting-state functional connectivity. The extent of experienced action crises was associated with enhanced fronto-accumbal connectivity signifying increased reward-related impact on prefrontal action control. Action crises, furthermore, mediated the relationship between a dispositional measure of effective goal pursuit (action orientation) and fronto-accumbal connectivity. The converging and complementary results from two methodologically different approaches advance the understanding of the neurobiology of personal long-term goals, especially with respect to the role of rewards in the context of goal-related conflicts.

    2012-04-01

    Full Text Available En 2007 et 2008 a éclaté la plus importante crise alimentaire depuis 1974. La hausse du prix des denrées alimentaires sur le marché international, en particulier du blé, du riz, du soja et du maïs, a entraîné une augmentation sans précédent du nombre de personnes sous-alimentées. Malgré une diminution relative du prix des denrées alimentaires depuis l’été 2008, le nombre de personnes sous-alimentées a continué à augmenter en 2009. Cette crise alimentaire a remis la lutte contre la faim au cœur des préoccupations internationales. Depuis le mois de mars 2008, les Etats, les agences des Nations unies et une grande partie des mouvements sociaux ont pris position sur les causes de la crise et les moyens d’y remédier. Malheureusement, alors que ces acteurs tentent de coordonner leurs activités et de proposer des solutions nouvelles, ce sont souvent des recettes anciennes, visant à augmenter la production alimentaire, qui sont mises en avant. Les propositions faites sont souvent contradictoires et les réflexions sur les causes profondes de la faim et de la crise alimentaire – les exclusions sociales, économiques et politiques et les discriminations – ne semblent pas avoir été entendues. Le premier Objectif du Millénaire pour le développement, qui vise à réduire de moitié la proportion des personnes souffrant de sous-alimentation et vivant dans l’extrême pauvreté d’ici 2015, est devenu clairement inatteignable. Mais la crise alimentaire pourrait être à l’origine de la création d’un nouvel ordre alimentaire mondial, basé sur les trois piliers que sont l’aide alimentaire, la sécurité alimentaire et le droit à l’alimentation.

    Full Text Available O artigo analisa o resultado de pesquisa realizada, em 2012, pelo Centro de Políticas Públicas e o Instituto de Sociologia da Pontifícia Universidade Católica de Chile sobre a Igreja Católica nesse país. Os dados do estudo mostram uma situação de crise do catolicismo chileno. Tal crise tem causas diversas, intra e extra eclesial: mudança cultural profunda, crise de identidade missionária da Igreja, crise de fé, crise de confiança, crise que convida a uma nova evangelização. A constatação dos limites da presença e influência da Igreja católica na era pós-moderna constitui desafio oportuno para se afirmar a importância da proposta do Cristianismo como caminho para a felicidade pessoal e para ajudar a construir uma sociedade onde reinem a justiça, a paz e a liberdade. O autêntico cristão vive a fé comprometido com a realidade integral do ser humano e da sociedade. Tal empenho se vincula ao sentido escatológico da fé e da vida eclesial. Os cristãos são chamados a manter viva a esperança, procurando superar a crise através da vivência da conversão e do perdão no seguimento de Jesus Cristo, sempre atentos aos sinais dos tempos. ABSTRACT: The article looks at the result of research carried out in 2012, by the Center for Public Policy and the Institute of Sociology of the Catholic University of Chile on the Catholic Church in that country. The data of the study show a crisis situation of Chilean Catholicism. This crisis has many causes, intra and extra ecclesial: a profound cultural change, a crisis of the Church’s missionary identity, a crisis of confidence, a crisis that calls for a new evangelization. The finding of the limits of the presence and influence of the Catholic Church in the post-modern era is a timely challenge to assert the importance of the proposal of Christianity as a path to personal happiness and to help build a society where justice, peace and freedom reign. The authentic Christian lives the

    Full Text Available Nos anos 1960, teve início a formação da rede de emigração da região de  Governador Valadares (MG para os Estados Unidos. Nos anos de 1980, essa rede  estava consolidada. Durante esse período, muitos retornaram, outros fixaram  residência no destino e outros tornaram-se transmigrantes. Em 2007, teve início  um retorno diferenciado, dos atingidos pela crise da economia americana. Este  artigo tem como tema central esse retorno. Foram realizadas 398 entrevistas com  emigrantes retornados no período de junho de 2007 a dezembro de 2008. Os  dados demonstram que a maioria deles são indocumentados, que ficaram nos  Estados Unidos por um período de três a cinco anos e retornaram porque os  ganhos já não compensavam os riscos. Em torno de 18% já fizeram investimentos  no Brasil que garantem sua sobrevivência, 51% têm capital para investir e 21%  não sabem como vão sobreviver no Brasil. Destaca-se que 28% pretendem emigrar  para Europa. Palavras-Chave: Crise Econômica. Migração. Retorno.   Abstract   The formation of a Brazilian  migration network from the Governador Valadares  region in Brazil to the  United States  began in the 1960s, and, by the 1980s, it was consolidated. During that period  many Brazilian immigrants returned to Brazil,  others continued to reside in the United States, while  some became transmigrants. In 2007 a different move began. The immigrants,  affected by the crisis of the U.S.  economy, start to return – and this is the focus of this article. I conducted  398 interviews with Brazilian migrants who returned to Brazil from  June, 2007 to December, 2008. Research results show that the majority of  Brazilian immigrants were undocumented, lived in the United States between three to  five years, and returned because their financial profits did not compensate the  risks anymore. About 18% had recently made investments in Brazil that would guarantee their survival; 51%  had

    Full Text Available Myasthenic crisis (MC is a life-threatening complication of myasthenia gravis (MG with a high mortality rate. The aim of our study was to review the different therapeutics approaches in the treatment of MC and their impact in the final outcome. We reviewed the medical files of patients diagnosed with MG admitted between February 1993 and October 1997, who developed MC. Sex, mean age, disease's duration, functional scale, symptoms preceding the crisis, crisis therapy in each set and mortality were then analysed. There were 24 patients who developed MC, 21 females and 3 males, with 1 neonatal, 1 congenital sporadic, 17 juvenile/adult, 3 over 50 years and 2 with thymoma. Dysphagia, dysphonia and dysartria were the most common symptoms preceding the crisis. A precipitating factor was elicited in 8 cases and the most common was infection (upper airway infection, urinary tract infection and pneumonia. 16 patients needed a nasogastric tube and 9 had a tracheostomy performed. 24 patients used anticholinesterase drugs, 21 prednisone, 7 immunosuppressive agents, 5 plasmapheresis, 3 human hyperimune gamma immunoglobulin and 12 had thymectomy. A good response was obtained in 13, satisfactory in 7 and there were 4 deaths. We concluded that in spite of all the therapeutics options, there were non statistically significant differences in the outcome of patients that underwent thymectomy and those who did not.A crise miastênica (CM é uma complicação preocupante da miastenia grave (MG que apresenta altos índices de mortalidade.

    Full Text Available L'inscription de la Belgique dans un processus continu de fédéralisation dissociative ne peut se comprendre qu'à travers une analyse des structures économiques du pays, à la fois sur les temps longs et dans le présent. L'idéologie identitaire qui domine en Flandre s'est développée en réaction à la crise séculaire de l'économie flamande entre le milieu du xixe siècle et l'entre-deux-guerres, ainsi qu'à l'arrogance francophone de la bourgeoisie nationale, mais aussi de celle des villes flamandes à l'époque. La crise de l'économie wallonne après la Seconde Guerre mondiale, similaire à celle de bien d'autres bassins d'ancienne industrialisation charbonnière et métallurgique, alors que la Région flamande connaissait un essor industriel, a généré dans le Nord du pays le sentiment que le Sud du pays devenait un fardeau pour son développement. Malgré le partage très majoritaire de l'usage du français, la Wallonie ouvrière a mis longtemps avant de prendre conscience de l'importance d'une solidarité économique (et politique avec Bruxelles, perçue comme « la ville des capitalistes ». En revanche, la Flandre considère Bruxelles comme sa capitale mais a peu d'empathie pour une ville francophone et cosmopolite. Toutefois, dans le cadre de la globalisation, Bruxelles apparaît comme le moteur de l'économie belge tertiarisée, ce qui en fait à la fois une pomme de discorde dans la vie politique belge, mais peut-être aussi un ciment pour le maintien d'une Belgique, dont les compétences qui resteront fédérales s'affaibliront en tout état de cause.Belgium's political evolution is part of a process of dissociative federalization. This can only be understood with reference to the country’s economic structures and their long-term trend. The community ideology prevailing in Flanders was developed as a reaction to the secular crisis of the Flemish economy, from the mid-19th Century to the inter-war, and to the arrogance
