Information Aggregation in Multidimensional Cheap Talk

I examine a cheap talk game with two decisions, two payoff-relevant states, and two senders. The model features interdependence because information about each state affects both decisions. Senders are imperfectly informed and communication depends on the nature of their information. I first analyse the case in which each sender observes a signal that fully reveals one of the states. I show that communication depends on how the interdependence aggregates decision-specific biases. This aggregation can lead to positive or negative informational spillovers, which affect communication incentives. Secondly, I analyse the case in which each sender observes noisy signals about both states. Some signals realizations update a sender's decision-specific posterior beliefs in different directions with respect to the prior which, in equilibrium, results in a loss of credibility that harms communication. However, this credibility loss leads to beneficial congestion effects.
The Ins and Outs of Selling Houses: Understanding Housing Market Volatility

This article documents the role of inflows (new listings) and outflows (sales) in explaining the volatility and comovement of housing‐market variables. An “ins versus outs” decomposition shows that both flows are quantitatively important for housing‐market volatility. The correlations between sales, prices, new listings, and time‐to‐sell are stable over time, whereas the signs of their correlations with houses for sale are found to be time‐varying. A calibrated search‐and‐matching model with endogenous inflows and outflows and shocks to housing demand matches many of the stable correlations and predicts that the correlations with houses for sale depend on the source and persistence of shocks.
Evaluation of Factor XII

Recurrent miscarriage is one of the most important causes of infertility and affects 2 to 4% of women in reproductive period (1). Recurrent miscarriages are defined as 2 consecutive or 3 and more non-consecutive pregnancy losses before the 20th gestational week (2). Moreover, as the number of miscarriages occurring during the previous pregnancy increases, the likelihood of miscarriage in the subsequent pregnancy increases (3). Although there are many etiologic factors, a specific cause cannot be identified in 30% to 40% of the recurrent miscarriages (4, 5). Fibrinolytic system plays an important role during early trophoblastic invasion (6). Therefore, factors such as the deficiency of factor XII activity or increase in plasminogen activator inhibitor, which negatively affects the fibrinolytic system, may limit trophoblastic invasion (6). After the effects of thrombophilic factors on the etiology of recurrent miscarriages were first described in the 1990s, many studies were reported on the effects of hereditary thrombophilias (7, 8). Although the role of especially antiphospholipid syndrome, which is among the acquired thrombophilias, in the etiology of recurrent miscarriages has been well studied, it has been reported that acquired factor 12 deficiency, which is a rare issue, may also be a cause (9). However, some studies have pointed out that the acquired factor XII deficiency may be a subgroup of the patients who have recurrent miscarriages and whose antiphospholipid antibodies are positive (10, 11).
Global Sourcing and Domestic Value-added in Exports∗

This paper employs data from the World Input-Output Database (WIOD) to document the evolution of the domestic content in exports, as measured by the domestic value added to gross exports ratio (DVAR), across countries and sectors over the period 1995-2008. We develop a multiple-sector general equilibrium model of Eaton and Kortum (2002) with domestic and global input-output linkages (a la Caliendo and Parro (2015)) to provide structural interpretations of individual countries’DVAR. We use the calibrated version of the model to fully decompose the time-series changes of the global DVAR and selected countries’DVAR into separate parts that are due to changes in technology, bilateral trade frictions, unilateral export fixed costs, and other exogenous factors such as changes in factor endowments and trade balances. We find that while the partial effects of both technology and trade costs are negative, there is a positive and significant interactive effect from the two. Taking into account the interactive effects, we find that the total effect of technology, which has been either overlooked or misinterpreted in the existing analyses of the evolution of global value chains, is significantly positive, while the total effect of trade frictions is far from capable of explaining the changes in DVAR over the sample period. The contributions of other determinants are quantitatively very small.

Draft ADOPTION AND TERMINATION OF EMPLOYEE INVOLVEMENT POLICIES

Employee Involvement (EI) programs in American manufacturing have been increasing, but these policies have not been universally successful. Many of these high performance workplace practices are not implemented properly or are abandoned. Yet the vast majority of research focuses on the adoption of these policies with little attention to those that are eliminated. Using a 10-year longitudinal database on U.S. manufacturing in union and nonunion establishments obtained through detailed plant visits, the study examines the trends and determinants of the adoption and termination of EI policies. The study develops an anatomy of employee involvement policies in the establishments of the most and least used elements of the overall policy. In addition, we compare the anatomy of EI in our sample to those in other similar studies. We find that the plants that have a high EI use are more likely to adopt another EI policy and more likely to abandon them as well; and that a set of other policies that are potentially complementary with employee involvement also affect the rate of adoption and decline of EI policies. Finally, we find that firms with higher levels of EI utilization have lower turnover rates.
Mortality rates due to Bladder cancer in Iran during 2001-2007: A national cancer registry-based study

Introduction: Bladder cancer is the ninth common cause of cancers in both sexes worldwide. Nevertheless, little is known about the descriptive and analytic epidemiology of bladder cancer in Iran. The present study aimed to describe the nationwide distribution of death due to bladder cancer in Iran. Methods: This cross-sectional study used data of bladder cancer cases who were registered in the national cancer-registry system by the Ministry of Health and Medical Education during 2001-2007. Age-standardized mortality rates due to bladder cancer were presented according to nine geographic poles across the country. Results: The overall mortality rate of bladder cancer (per 100,000 population) was 2.26 in men and 1.36 in women; while the rates were constantly higher for men across all age groups. The highest and lowest age-standardized mortality rates in provinces (per 100,000 population) belonged to Mazandaran (6.126) and Tehran (1.112), respectively. Conclusion: Death from bladder cancer seems to increase by age in Iran, mainly among men. This association might be partially due to increased life expectancy, altered high-risk lifestyle behaviors and/or improvement in cancer registration system. Information on the distribution of mortality due to bladder cancer could be useful for local prevention strategies, where specific profile of communities and patients is taken into account.
The least degree of a CM point on a modular curve

For a modular curve X=X0(N)$X = X_0(N)$ , X1(N)$X_1(N)$ or X1(M,N)$X_1(M,N)$ defined over Q$\mathbb {Q}$ , we denote by dCM(X)$d_{\operatorname{CM}}(X)$ the least degree of a CM point on X$X$ . For each discriminant Δ<0$\Delta < 0$ , we determine the least degree of a point on X0(N)$X_0(N)$ with CM by the order of discriminant Δ$\Delta$ . This places us in a position to study dCM(X)$d_{\operatorname{CM}}(X)$ as an ‘arithmetic function’ and we do so, obtaining various upper bounds, lower bounds and typical bounds. We deduce that all but finitely many curves in each of the families have sporadic CM points. Finally, we supplement these results with a computational study, for example, computing dCM(X0(N))$d_{\operatorname{CM}}(X_0(N))$ and dCM(X1(N))$d_{\operatorname{CM}}(X_1(N))$ exactly for N⩽106$N \leqslant 10^6$ and determining whether X0(N)$X_0(N)$ (respectively, X1(N)$X_1(N)$ , X1(M,N)$X_1(M,N)$ ) has sporadic CM points for all but 106 values of N$N$ (respectively, 227 values of N$N$ , 146 pairs (M,N)$(M,N)$ with M⩾2$M \geqslant 2$ ).

Initial T wo-Year Experience with Lap aroscopic Colorect al Surgery in a Service in Salvador , Bahia, Brazil: A Critical Analysis Experiência Inicial de Dois Anos em Cirurgia Colorret al Videolap aroscópica em um Serviço em Salvador: Uma Análise Critica

Introduction: Since the first reports by Jacobs in 1990, colorectal surgery is increasingly performed via videolaparoscopic access, shortening hospital stays, and offering patients better esthetic results, less postoperative pain, and an earlier resumption of their work and leisure activities. Objective: to report a case series of a team using videolaparoscopic access. Methods: Retrospective, descriptive study cases performed from April 2010 to May 2012 in Salvador, Bahia, Brazil. Results: 81 procedures were analyzed, 59.3% of the patients were female. Mean age was 58.3 years. Benign disorders were treated in 48.1% of the cases. Rectosigmoidectomy was performed in 41.5% and right colectomy in 21% of cases. The intraoperative complication rate was 3.7%; the postoperative rate 21%. The conversion rate was 6.2%. Conclusions: Videolaparoscopic procedures are safe and the training of the surgeons has yielded better results in this case series.
PERCEPTION OF FACILITATORS ON THE INTRODUCTION OF THE USE OF MOBILE PHONE FOR INSTRUCTION IN ADULT LITERACY PROGRAMMES IN IBADAN METROPOLIS

This study investigated the perception of facilitators on the use of mobile phone for instruction in adult literacy programmes. The survey research design was adopted and the purposive sampling technique used in selecting fifty (50) participants for the study. Data collected through a set of researcher-designed questionnaire were analysed using descriptive statistics of simple percentages and frequency counts. Results revealed that facilitators have a positive perception on the use of mobile phone for administrative and instructional purposes (Weighted Average (WA) = 3.15). Challenges likely to be faced by adult literacy facilitators in the use of mobile phones in adult literacy programmes include lack of adequate training (mean=3.24), limited number of file formats supported by a specific mobile phone (mean=3.00), additional time needed to develop learning materials for delivery on mobile phone (mean=3.20), risk of distraction (mean=3.00), insufficient knowledge and skills of facilitators on mobile phone use (mean=2.84) and the appropriate content and language of instruction (mean=3.04, SD=0.75). It was recommended based on these findings that government at all levels should endeavour to organise regular and adequate training for facilitators on the use of mobile phone for adult learning.
Coronary Endarterectomy: a Case Control Study and Evaluation of Early Patency Rate of Endarterectomized Arteries

Objective To compare two groups of patients - the coronary endarterectomy group, with patients undergoing coronary artery bypass grafting (CABG) with coronary endarterectomy (CE), and the control group, with patients undergoing CABG without CE. We analyzed the rate of major outcomes (perioperative acute myocardial infarction [AMI], stroke, and mortality) and minor outcomes (time of cardiopulmonary bypass [CPB], time of aortic clamp, and postoperative length of hospital stay). We also determined the rates of early graft patency in patients undergoing CE. Methods We reviewed a database of patients submitted to CABG, with or without associated CE, between January 2011 and June 2017. Twenty-five patients submitted to CE were compared with 201 patients submitted only to conventional surgery; the two groups presented similar preoperative characteristics and all the European System for Cardiac Operative Risk Evaluation (EuroSCORE) II variables did not presented statistically significant difference. We considered statistically significant values of P< 0.05. Results There was no statistically significant difference in relation to time of post-surgical hospitalization (P=0.8139), incidence of perioperative AMI (P=0.2976), stroke (P=0,2976), and mortality rate (P=1.0000), but endarterectomy was associated with longer aortic clamping time (P=0.0004) and CPB time (P=0.0030). The rate of patency evaluated in patients submitted to endarterectomy (78,95%) was compatible with that described in the literature. Conclusion In this sample, coronary endarterectomy was associated with the rate of early graft patency similar to that of the literature, with morbidity and mortality rates similar to those of conventional surgery.
Muscle cramps — a mini review of possible causes and treatment options available with a special emphasis on diabetics — a narrative review

Muscle cramps are characterized by sudden, painful involuntary contraction of the muscles. The cramps sometimes become disabling and the prevalence is more in the elderly. The etiology of the cramps are diverse and some time the cramps are idiopathic. There are many underlying pathophysiological disorders like hypocalcemia, hypomagnesemia, hypothyroidism, and hepatorenal dysfunction which causes muscle cramp. Similarly, diabetes mellitus results in muscle cramps due to electrolytic imbalance, hypoglycemia, peripheral arterial insufficiency, and neuropathies. Persistent muscle pain in diabetic patients degrades the quality of life of those patients. Although the pathophysiology and etiology of the muscle cramp are understood to some extent, the same is less explored from diabetes mellitus perspective. Hence the objective of this review is to explore the underlying factors responsible for muscle cramps in diabetes so that proper strategy for pharmacotherapy can be made to manage this condition.
Fragility curves of RC columns estimated by the CAE method

In the paper an alternative empirical approach for the estimation of fragility curves for RC columns is proposed. The CAE (Conditional Average Estimator) method was used. The procedure includes the LHS method, which was applied in order to take into account different uncertainties. The result of the study are estimated fragility curves for typical reinforced concrete (RC) columns (1) designed without seismic detailing, (2) designed according to first seismic codes used in the former Yugoslavia and (3) designed according to Eurocode 8. The obtained results clearly reveal the higher deformation capacity of RC columns, designed according to Eurocode 8. Additionally, the fragility curves related to various damage states, i.e. concrete crushing, longitudinal bar buckling, and longitudinal bar fracture were estimated. It is concluded that the proposed procedure offers a viable alternative to existing approaches.
IAC-11.A2.6.4 NUCLEATE BOILING IN LONG-TERM CRYOGENIC PROPELLANT STORAGE IN MICROGRAVITY

Efficient storage of cryogenic propellants in zero-gravity or microgravity environments is one of the key requirements to enable new long-range space exploration missions currently envisioned by NASA. Recent advances in multi-layer insulation (MLI) allow to sharply reduce the heat leak into cryogenic propellant storage tanks through the tank surface and, as a consequence, significantly extend the storage duration. In this situation the MLI penetrations, such as support struts, feed lines, etc., become significant challenges of the tank’s heat management. This problem is especially acute for liquid hydrogen (LH2) storage, since currently no efficient cryocoolers exist that operate at very low LH2 temperatures (∼20K). In the absence of active cooling the heat leaks through the MLI penetrations will inevitably cause the onset of localized boiling at the tank walls. Our estimates show that for realistic values of local heat inflow the rate by which vapor bubbles are generated near the penetrations will exceed by one or several orders of magnitude the rate of bubble collapse in the subcooled liquid. Therefore, with time vapor bubbles may accumulate within the liquid and drift towards the stagnation areas of the liquid flow in the presence of mixers. Thus, even small heat leaks under microgravity conditions and over the period of many months may give rise to a complex slowly-developing, large-scale spatiotemporal physical phenomena in a multi-phase liquid-vapor mixture. These phenomena are not well-understood nor can be easily controlled. They can be of a potentially hazardous nature for long-term on-orbital cryogenic storage, propellant loading, tank chilldown, engine restart, and other in-space cryogenic fluid management operations. We performed some basic physical estimates to evaluate the relative importance of different physical processes during long-term cryogenic storage of LH2. Our main goal was to identify the processes and issues, such as safety hazards and design optimization parameters, which arise specifically during extended periods in zeroand microgravity. The next step in developing a better physical understanding of long-term cryogenic storage systems and finding new engineering design solutions is to obtain new fundamental data from on-orbit cryogenic storage experiments. We propose a conceptual design for an ISS-based medium-scale cryogenic storage tank experiment that would probe vapor bubble formation, growth, motion, coalescence and collapse in the presence of localized heat sources in a microgravity environment in the presence of stirring jets of different configurations and passive cooling devices such as MLI, thermodynamic vent system, and vapor-cooled shield.
A Three-Wave Longitudinal Study of Moderated Mediation between Perceptions of Politics and Employee Turnover Intentions: The Role of Job Anxiety and Political Skills

This study examined a longitudinal moderated mediation model for answering the question of how and why perceptions of organizational politics influence turnover intentions, and how employees’ political skills are contingent upon this relationship by reducing job anxiety. Data were gathered in three waves from employees in the banking sector (N = 347). The results of multiple linear regression analyses indicate that job anxiety mediates the relationship between perceptions of politics and turnover intentions, and employees’ political skills reduce turnover intentions by weakening the effect of perceptions of politics on job anxiety. This study contributes to human resource management and organizational psychology literature by explaining moderated mediation mechanisms through which perceptions of organizational politics affect employee turnover intentions.
Collinear interaction of vortex pairs with different strengths—Criteria for leapfrogging

We formulate a system of equations that describe the motion of four vortices made up of two interacting vortex pairs, where the absolute strengths of the pairs are different. Each vortex pair moves along the same axis in the same sense. In much of the literature, the vortex pairs have equal strength. The vortex pairs can either escape to infinite separation or undergo a periodic leapfrogging motion. We determine an explicit criterion in terms of the initial horizontal separation of the vortex pairs given as a function of the ratio of their strengths to describe a periodic leapfrogging motion when interacting along the line of symmetry. In the Appendix, we also contrast a special case of interaction of a vortex pair with a single vortex of the same strength in which a vortex exchange occurs.
Role of Cd and Hg on biochemical contents of fennel and its reduction by exogenous treatment of nitrogen

Heavy metal contamination is a serious environmental problem that limits crop production and endangerous for human health. The present study was conducted at Department of Botany, School of Life Sciences, Dr. B.R. Ambedkar University, Agra for assessing the toxic effect of cadmium and Mercury at different concentration viz. 10, 20 and 50 μm on the chlorophylls, proline and protein content of Foeniculum vulgare L. The standard solution was prepared using standard metal of inorganic ventures. These heavy metals affected the chlorophylls, carotenoids, protein and proline content of fennel seedlings as compared to control. Carotenoids were less effected as compared to chlorophyll 'a' and 'b' at low concentration (10μm), while at higher concentrations i.e. 20 and 50μm, the chlorophylls, carotenoids and protein content of the seedlings were reduced drastically. However the addition of nitrogen (5 mM) minimize the effect of these heavy metals to some extent. The proline content of plants was increased under Cd and Hg treatments at all concentrations. However in this case additional supply of nitrogen in the form of Ammonium nitrate decreased proline content of plants at all concentrations of these heavy metals (Cd and Hg).
