The Impact of High-Performance Work Systems on Employees: A Sectoral Comparison

Using nationally representative linked employer-employee surveys of workplaces with 50 or more employees we find the adoption of High-Performance Work Systems (HPWS) in the private sector is largely positively correlated with employee job attitudes pre-recession. However, high intensity HPWS has partly adverse consequences for private sector employees in the post-recession period. In contrast, there are no indications of public sector employees responding positively or negatively to HPWS and HPWS is not associated with adverse effects post-recession. The sectoral difference in results is interpreted in terms of different employment relationships and different sources of employee motivation.
Trend Inflation and Asset Pricing in a DSGE Model: Comment

We show that the ability of the Rudebusch and Swanson (2012) model to match a large and variable term premium without compromising the model’s ability to fit key macroeconomic variables relies on zero trend inflation – an assumption that contradicts recent empirical findings which emphasize low-frequency movements in inflation as a key determinant of term structure. We show that a model version that corrects for the presence of trend inflation delivers implausible business cycle and bond price dynamics. This result is driven by the behavior of price dispersion, which is i) counterfactually high and ii) highly inaccurately approximated. We document several model extensions which can to some degree restore the earlier success of the Rudebusch and Swanson model.
The smarter, the cheaper1 Aging, bounded rationality and the natural rate of interest

This paper revises the secular stagnation hypothesis through the lens of bounded rationality. The consequences of population aging on medium and long-term equilibrium are at the center of today’s discussion of macroeconomics. According to the secular stagnation hypothesis in aging societies the GDP growth decelerates and the natural rate of interest decreases when the households cumulate more savings for the longer lifetime span. However, this model prediction can be rejected or weakly explained by historical data of OECD countries. To the best of my knowledge, this is the first paper on multi-period Gertler-type OLG-model that incorporates bounded rationality and empirically shows that negative relationship between old-age dependency ratio and real interest rate can only be valid for those countries where the agents’ behavior is consistent with the rational expectation equilibrium or the agents have relatively long planning horizon.

Incorporating Super-Operators in Big-Data Query Optimizers

The cost of big-data analytics is dominated by shuffle operations that induce multiple disk reads, writes and network transfers. This paper proposes a new class of optimization rules that are specifically aimed at eliminating shuffles where possible. The rules substitute multiple shuffle inducing operators ( Join, UnionAll, Spool, GroupBy ) with a single streaming operator which implements an entire sub-query. We call such operators super-operators. A key challenge with adding new rules that substitute sub-queries with super-operators is that there are many variants of the same sub-query that can be implemented via minor modifications to the same super-operator. Adding each as a separate rule leads to a search space explosion. We propose several extensions to the query optimizer to address this challenge. We propose a new abstract representation for operator trees that captures all possible sub-queries that a super-operator implements. We propose a new rule matching algorithm that can efficiently search for abstract operator trees. Finally we extend the physical operator interface to introduce new parametric super-operators. We implement our changes in SCOPE, a state-of-the-art production big-data optimizer used extensively at Microsoft. We demonstrate that the proposed optimizations provide significant reduction in both resource cost (average 1.7x) and latency (average 1.5x) on several production queries, and do so without increasing optimization time.
2 0 N ov 2 01 9 Two properties of the partial theta function

For the partial theta function θ(q, z) := ∑ ∞ j=0 q z, q, z ∈ C, |q| < 1, we prove that its zero set is connected. This set is smooth at every point (q, z) such that z is a simple or double zero of θ(q, .). For q ∈ (0, 1), q → 1− and a ≥ e, there are o(1/(1 − q)) and (ln(a/eπ))/(1− q) + o(1/(1− q)) real zeros of θ(q, .) in the intervals [−eπ, 0) and [−a,−e−π] respectively (and none in [0,∞)). For q ∈ (−1, 0), q → −1+ and a ≥ e, there are o(1/(1+ q)) real zeros of θ(q, .) in the interval [−eπ/2, e] and (ln(a/e)/2)/(1 + q) + o(1/(1 + q)) in each of the intervals [−a,−eπ/2] and [e, a].
Seroepidemiology of varicella-zoster virus among pregnant women in Hamedan, Iran

Varicella is a highly contagious illness that is severe and associated with a greater risk of complications and death in adults than in children . The disease in pregnant women may result in congenital varicella syndrome. The aim of this study was to determine the immunity level against varicella-zoster virus among pregnant women in Hamedan, Iran. During a cross-sectional study, blood samples of 270 pregnant women who were referred to the Fatemieh hospital during a six-month period were taken after they filled out the relevant questionnaires and the agreements. The level of IgG against varicella-zoster virus was measured using ELISA method. The collected data was analyzed by SPSS 16. Out of 270 pregnant women, 210 (78.5%) had protective levels of IgG against varicella-zoster virus and 21.5% were not immune against it. Immunity development had no significant relationship with the place of residence, education, job and the history of infection with chickenpox in the examined person as well as, her maternal education and occupation. Our results seem to indicate that pregnant women in this region need special care when it comes to contacts with chicken pox patients, given the sensitivity of a significant portion of this group to the primary varicella infection.
Maternal near miss morbidity in Colombia: variables related to opportune access to health care related to the number of inclusion criteria

Background. In Colombia, maternal near miss morbidity is monitored in the health surveillance system. The National Health Institute included a special report on cases that met three or more World Health Organization criteria according to the World Health Organization criteria. Objective. To estimate the relationship between variables related to opportune access to health care services in Colombia during 2013 depending on inclusion criteria –three or more– for maternal near miss morbidity. Materials and methods. A cross-sectional analysis of the national registry of obligatory notification on maternal near miss morbidity was performed. Cases with three or more criteria were compared with those with one or two according to some variables related to the timely access of health care services. Results. A total of 8 434 maternal near miss morbidity cases were reported, women were aged between 12 and 51 years old (M=26.4, SD=7.5). 961 (11.4%) lived in remote rural areas; 4 537 (53.8%) were uninsured under the health system, or they were affiliated to either the subsidized or special health care regime; 845 (10.0%) belonged to an ethnic minority; 3 696 (44.4%) were referred to a more complex service; 4 097 (49.2%) were admitted to the intensive care unit; and 3 975 (47.1%) met three or more of the inclusion criteria for maternal near miss morbidity. They were combined to meet three or more of the case inclusion criteria: intensive care unit admission (OR=5.58;IC95% 5.06-6.15); being uninsured or affiliated to the subsidized or special regime (OR=1.57; IC95% 1.42-1.74); and referral to a more complex service (OR=1.18; IC95% 1.07-1.31). Conclusions. In Colombia, the timely access of health care services is related to maternal near miss morbidity with three or more inclusion criteria.

Attitudes des médecins omnipraticiens et des résidents en médecine familiale à l’endroit des personnes souffrant d’un trouble de personnalité limite

Plusieurs etudes suggerent que les professionnels de la sante entretiennent des attitudes negatives a l’egard des personnes presentant un trouble de personnalite limite (TPL). Cette recherche vise a evaluer les attitudes des omnipraticiens et des residents en medecine familiale a l’endroit des personnes presentant ce trouble. Quarante residents en medecine familiale et trente-cinq omnipraticiens ont ete compares a trente-neuf professionnels de la sante mentale a l’aide de l’Echelle d’attitudes a l’egard des personnes presentant un TPL (EA-TPL ; Bouchard, 2001). Les resultats demontrent que les omnipraticiens et les residents en medecine familiale endosseraient des attitudes similaires a celles des professionnels de la sante mentale envers les personnes presentant ce trouble et que moins les cliniciens sont experimentes, moins ils auraient tendance a presenter des attitudes positives a l’egard des personnes ayant un TPL.
Comment on: Surgical resection versus transarterial chemoembolization for BCLC stage C hepatocellular carcinoma

Background Sorafenib is the only recommended treatment for patients with Barcelona Clinic Liver Cancer (BCLC) stage C hepatocellular carcinoma (HCC). We aimed to compare surgical resection (SR) and transarterial chemoembolization (TACE) for advanced (BCLC stage C) HCC patients. Methods A total of 264 and 389 advanced HCC patients received SR and TACE, respectively. Among them, 163 matched pairs of patients were identified from each treatment arm by propensity score matching analysis to compare long-term survival. Results Of all patients, the SR group had better liver functional reserve than the TACE group. In the matched propensity model, the baseline characteristics were similar between patients receiving SR and TACE. SR provided significantly better long-term survival than TACE in all patients and in patients selected in the propensity model (both P < 0.001). In the Cox proportional hazards model, patients receiving TACE had a 2.393-fold increased risk of mortality compared with patients receiving SR (95% confidence interval: 1.610–3.556, P < 0.001). Conclusions SR provides significantly better long-term survival than TACE in patients with BCLC stage C HCC, and should be an integral part in the management of advanced HCC. Multidisciplinary approaches for these patients and further amendment to the BCLC classification scheme are required. J. Surg. Oncol. 2015 111:404–409. © 2015 Wiley Periodicals, Inc.
Variations in hospital quality and outcomes under a financial incentive scheme

High and equitable quality of care are core goals of the English National Health Service. Policy makers have experimented with various ways to improve quality, including use of financial incentives. The effects of these incentives on health outcomes and the distribution of care are not known. The aim of this study was to examine variations in hospital quality and outcomes at patient level under a financial incentive scheme in England.In October 2008 a financial incentive scheme under which quality of care was measured by process measures was introduced for 24 hospital Trusts in the North West of England. The process measures of care from this Advancing Quality initiative were linked at spell level to health outcomes and administrative hospital records. The data consisted of 252,284 spells between October 2008 and March 2013.First, I examined whether financially incentivised improvements in quality of care were associated with better patient outcomes. I examined how mortality and readmission were related to process measures using bivariate probit, probit, random effects and fixed effects estimations. I found that several of the incentivised process measures of care are associated with improved patient outcomes. I estimated that Advancing Quality saved 129 lives and avoided 121 readmissions over a four-and-a-half year period.Second I examined whether quality of care from a hospital incentive scheme is distributed equitably at a patient level. Multinomial and sequential logistic regressions were used to show that process measures of care overall were distributed in favour of patients from lower income score areas. Process measures of care delivered during an emergency admission were distributed in favour of patients from higher income score areas but this was driven by patient severity. Process measures based on advice appeared to be driven by capacity to benefit and were distributed in favour of patients from lower income score areas. Process measures of care for elective admissions regarding delivery of drugs were distributed equitably.Third, I examined if the quality of care was lower at the weekend. The in-hospital mortality rate is known to be higher for weekend admissions than for weekday admissions but it is not known whether this was due to lower quality of care. Using logistic regressions, incentivised quality of care was found to be consistent throughout the week. The weekend mortality effect can be explained by patient volume, which suggested that patient case mix may be different between weekdays and weekends.Overall, quality of care under an incentive scheme was found to positively impact on health outcomes, be distributed equitably, and be the same at weekends as weekdays. Further research is needed using quality of care indicators from all Trusts in the English National Health Service. Furthermore further research examining how trusts exclude patients from financial incentive schemes is also needed.
Severe Maternal Morbidity and Near Misses in Two Tertiary Referral Hospitals in Iran

Background: Investigating severe maternal morbidity/near miss is a newly recognized tool which identifies women at the highest risk of maternal death and helps allocate resources, especially in developing countries. Objectives: This study aimed to document the prevalence and causes of severe maternal morbidity (SMM) at two educational hospitals in Ahvaz, Khuzestan, Iran. Patients and Methods: In this prospective study, we found and selected SMM patients based on organ failure criteria from patients admitted in two educational hospitals of Ahvaz Jundishapur University of Medical Sciences during 2009 - 2010. Until recovery discharge or death, the diagnosis and management of these patients were under observation of obstetricians. The main outcome was maternal mortality ratio, SMM rate (SMMR). Results: Totally, there were 12,149 deliveries, eight maternal deaths and 226 SMM cases. This study showed the SMMR of 18.6/1000 live births, an MMR of 65.8/100000 live births, and case fatality ratio of 1/28 or 3.5%. Severe preeclampsia and hemolysis elevated liver enzymes low platelet count syndrome (HELLP) (38%), hemorrhage (23%) and ectopic pregnancy (14%) were the top causes of SMM. Similar to HELLP syndrome (25%) hemorrhage (25%), sepsis (25%) was the commonest cause of mortality; 39% of patients were referred from primary or secondary health care units; 85% of the cases needed intensive care unit admissions. Conclusions: SMM analysis provides valuable information on obstetric care. This study highlighted the need to improve antenatal care, which would help early identification of high-risk pregnancies. Every SMM could progress to maternal mortality if is not suspected, diagnosed and managed on its golden time.
The effect of health education in promoting health of hairdressers about hepatitis B based on health belief model: a field trial in Yazd Iran.

Hepatitis B (HB) is an infectious disease occurring worldwide which can be transferred by some professions including hairdressers. Health education is an essential component of public health campaign about this disease. The purpose of this study was to test the utility of the health belief model (HBM) in understanding and predicating the intention of hairdressers in prevention of HB in their clients. A quasi-experimental study was conducted to 140 hairdressers (70 men and 70 women) in Yazd Iran. All subjects were divided into two groups: case group (35 men and 35 women) and control group (35 men and 35 women). A researcher designed questionnaire according to the framework of HBM was developed pilottested and then completed before and after intervention. There was significant difference between the mean grade scores of knowledge of case group before and after intervention (P < 0.0001). The perceived threat of case group were also increased from 9.8 to 10.61 after intervention but the perceived threat of control group were decreased from 9.97 to 9. The HBM may offer an effective foundation for development of an educational intervention program in hairdressers for prevention of HB in their clients. (authors)
