Incorporating Labour Market Frictions into an Optimising-Based Monetary Policy Model

This paper examines the effects of introducing a non Walrasian labour market into the "New Neoclassical Synthesis'' framework. A dynamic stochastic general equilibrium model is formulated, solved, and calibrated in order to evaluate its ability to replicate the main features of the Euro area economy. This framework allows us to study the effects of labour market rigidities, nominal rigidities, and other frictions to give account of the impact of monetary policy, technology, public spending, and preference shocks. Our simulations show that: (i) real rigidities complement but do not supplant nominal rigidities, (ii) the Beveridge and Phillips relations are reproduced, (iii) hours worked are too sensitive an adjustment variable, and (iv) the real wage dynamics is still procyclical.DSGE models ; Nominal rigidities ; Real rigidities ; Labour market ; Endogenous persistence ; Euro area

Regional Disparities and Investment-Cash Flow Sensitivity: Evidence from Chinese Listed Firms

In China, regional disparities are important. We examine the difference in the sensitivity of investment to cash flow between firms in inland regions and those in coastal regions. By using the financial data of Chinese listed firms, we found that firms in inland regions rely more on their internal funds in terms of their investment activities than those in coastal regions and that the sensitivity gap between inland and coastal firms widened in the recent contractionary monetary policy period. This suggests that firms in inland regions are harder to obtain outside funds due to unfavorable social and economic environments for inland firms. Our findings suggest that capital markets in China respond rationally to the potential impact of regional disparities on a firm’s performance

School Delay of Child in Brazzaville (Congo)

Abstract The aim of this study was to determine the prevalence of school delay in school age children and to identify its determinants in Brazzaville. A case-control study, comparing school age children with a school delay (Group 1 or cases) to those who had not school delay (Group 2 or control), was carried out between February and July 2013. It included students of CM2 (primary 6) and those of 3 ème (form 4) of both public and private schools of Brazzaville. The sample selection was made according to a random survey by strata, the number of strata was set to 2. The sample consisted of 2064 pupils including 1138 girls (55.1%). A total of 2064 students (1138 male/926 female), 792 of them had a school delay, with a prevalence of 38.3%. It was 27% in the private sector and 46.9% in the public one; 28.2% in primary education compared to 48.1% in the college; 27.8% in girls and 48.8% in boys (p < 0.001). 21.4% of students in CM2 (primary 6) of the public and 16.7% in the private sector had repeated classes 3 times; 4.2% of students in 3ème (form 4) of the public education had repeated classes 4 times. Kindergarten program attendance had a positive effect on later school performances (p < 0.05). The parent's level of education and socio-economic status of the family (low and mean for students in CM2 of public schools and of 3ème of private schools, high for pupils in CM2 of private schools) and underweight among pupils in CM2 of the private sector were significantly correlated with school delay (p < 0.05). The prevalence of school delay was high in Brazzaville (38.3%), boys were more affected than girls. The kindergarten program attendance was found to have a positive effect on later school performances, while parent's low level of education and low socioeconomic status of the family significantly influenced the rate of school delay in children in Brazzaville. The high prevalence of school delay in child in Brazzaville imposed substantial actions, in addition to the efforts already made. Keywords School Delay, Child, Brazzaville J. R.

A large-scale study of a poultry trading network in Bangladesh: implications for control and surveillance of avian influenza viruses

Since its first report in 2007, avian influenza (AI) has been endemic in Bangladesh. While live poultry marketing is widespread throughout the country and known to influence AI dissemination and persistence, trading patterns have not been described. The aim of this study is to assess poultry trading practices and features of the poultry trading networks which could promote AI spread, and their potential implications for disease control and surveillance. Data on poultry trading practices was collected from 849 poultry traders during a cross-sectional survey in 138 live bird markets (LBMs) across 17 different districts of Bangladesh. The quantity and origins of traded poultry were assessed for each poultry type in surveyed LBMs. The network of contacts between farms and LBMs resulting from commercial movements of live poultry was constructed to assess its connectivity and to identify the key premises influencing it

Obesity, but not hypohydration, mediates changes in mental task load during passive heating in females

Background The independent effects of hypohydration and hyperthermia on cognition and mood is unclear since the two stresses often confound each other. Further, it is unknown if obese individuals have the same impairments during hyperthermia and hypohydration that is often observed in non-obese individuals. Methods The current study was designed to assess the independent and combined effects of mild hypohydration and hyperthermia on cognition, mood, and mental task load in obese and non-obese females. Twenty-one healthy females participated in two passive heating trials, wherein they were either euhydrated or hypohydrated prior to and throughout passive heating. Cognition (ImPACT), mental task load (NASA-TLX), and mood (Brunel Mood Scale; BRUMS) were measured before and after a 1.0 °C increase in core temperature (TC). Results After a 1.0 °C TC elevation, hypohydration resulted in greater (p  0.05). Hyperthermia, regardless of hydration status, impaired (∼5 A.U) measures of memory-based cognition (verbal and visual memory), and increased mental task load, while worsening mood (p  0.05). Conclusion These data indicate that hyperthermia independently impairs memory-based aspects of cognitive performance, mental task load, and leads to a negative mood state. Mild hypohydration did not exacerbate the effects of hyperthermia. However, obese individuals had increased mental task load during hyperthermia

Prevalence of avian influenza A(H5) and A(H9) in live bird markets in Bangladesh

We conducted a cross-sectional study in live bird markets (LBMs) in Dhaka and Chittagong, Bangladesh, to estimate the prevalence of avian influenza A(H5) and A(H9) viruses in different types of poultry and environmental areas by using Bayesian hierarchical logistic regression models. We detected these viruses in nearly all LBMs. Prevalence of A(H5) virus was higher in waterfowl than in chickens, whereas prevalence of A(H9) virus was higher in chickens than in waterfowl and, among chicken types, in industrial broilers than in cross-breeds and indigenous breeds. LBMs with >1 wholesaler were more frequently contaminated by A(H5) virus than retail-only LBMs. Prevalence of A(H9) virus in poultry and level of environmental contamination were also higher in LBMs with >1 wholesaler. We found a high level of circulation of both avian influenza viruses in surveyed LBMs. Prevalence was influenced by type of poultry, environmental site, and trading patterns because our study included previously collected data

Evaluation of drug administration errors in a teaching hospital

<p>Abstract</p> <p>Background</p> <p>Medication errors can occur at any of the three steps of the medication use process: prescribing, dispensing and administration. We aimed to determine the incidence, type and clinical importance of drug administration errors and to identify risk factors.</p> <p>Methods</p> <p>Prospective study based on disguised observation technique in four wards in a teaching hospital in Paris, France (800 beds). A pharmacist accompanied nurses and witnessed the preparation and administration of drugs to all patients during the three drug rounds on each of six days per ward. Main outcomes were number, type and clinical importance of errors and associated risk factors. Drug administration error rate was calculated with and without wrong time errors. Relationship between the occurrence of errors and potential risk factors were investigated using logistic regression models with random effects.</p> <p>Results</p> <p>Twenty-eight nurses caring for 108 patients were observed. Among 1501 opportunities for error, 415 administrations (430 errors) with one or more errors were detected (27.6%). There were 312 wrong time errors, ten simultaneously with another type of error, resulting in an error rate without wrong time error of 7.5% (113/1501). The most frequently administered drugs were the cardiovascular drugs (425/1501, 28.3%). The highest risks of error in a drug administration were for dermatological drugs. No potentially life-threatening errors were witnessed and 6% of errors were classified as having a serious or significant impact on patients (mainly omission). In multivariate analysis, the occurrence of errors was associated with drug administration route, drug classification (ATC) and the number of patient under the nurse's care.</p> <p>Conclusion</p> <p>Medication administration errors are frequent. The identification of its determinants helps to undertake designed interventions.</p
