A study of vaginismus in patients presenting with infertility

Background: Vaginismus is an uncommonly reported entity, most of the patients present to the gynaecologist with complaint of inability to conceive. Female sexual dysfunctions are a common entity but difficult to diagnose and treat, Vaginismus is one of the categories of female sexual dysfunction.Methods: Total 25 patients out of 900 patients attending the outdoor of Shivanjali Women’s Hospital for infertility from the year 2008 to 2016 were found to be having vaginismus. With couple’s consent females were treated for vaginismus. This is a retrospective study of 25 patients identified having vaginismus.Results: Maximum 11 patients were in age group of 20 to 25 years. Forty percent 10 patients improved with counselling and education, lubricant gel and analgesic gel. Total 84% (21) patients conceived with different modes of treatment.Conclusions: Vaginismus is uncommonly reported. With proper history and counselling of the couple vaginismus can be revealed, managed and conception can be achieved

(In)Stability of the relationship between relative expenditure and prices of durable and non-durable goods

This study shows that, in a model with non-separable preferences for durable and non-durable goods, the effect of relative prices on the ratio of consumption for the two goods, known as the intratemporal elasticity of substitution, has decreased in the U.S. since 1981. We found that durable and non-durable goods were gross substitutes until 1981 and have been gross complements in the period after that. This break also had significant implications for short-term consumption dynamics. Although durable goods still drive most of the adjustment towards long-term equilibrium in non-durables, durables, and relative prices, the size of the adjustment has significantly decreased in the post-1981 period, suggesting slower convergence towards long-run equilibrium. Additionally, we found that the durable goods cycle has become more persistent over time. During the recent pandemic, durable goods were more than 20% above the long-term common trend that they share with non-durable goods and their relative prices. The findings of this study also have implications for the global supply chain pressures that have contributed to rapid inflation in the post-COVID period. The estimated durable goods cycle and the Global Supply Chain Pressure Index exhibit a non-linear relationship, where a deviation of more than 4.8% from the long-term common trend leads to a significant increase in the supply chain pressure index

(A)Synchronous Housing Markets of Global Cities

In this paper we examine house price synchronization in 15 global cities using real house price data from 1995:Q1-2020:Q2. We find that although there is evidence for bilateral positive phase synchronization, there is no evidence for an integrated global housing market for our sample of cities. Using a hierarchical clustering approach, we identify three clusters of cities with similar housing price cycles that are not solely determined by geographic proximity. We interpret this finding as suggestive of a rather segmented housing market for the global cities in our sample. Using a dynamic factor model with time-varying stochastic volatility we decompose a city's real housing price growth into a global component, a cluster-based component, and an idiosyncratic component. For most cities in our sample, the global component plays a minor role, whereas the cluster-based factor explains a large fraction of the observed variation in real house price growth with its contribution peaking during the Great Recession of 2007-0

Estimating excess sensitivity and habit persistence in consumption using Greenbook forecast as an instrument

In this paper, we revisit the issue of excess sensitivity of consumption to income and address the weak instrument problem that is well documented in this literature. Using quarterly data for the U.S. economy, we first highlight the weak instrument problem by showing that the use of conventional instruments tends to overestimate the share of rule-of-thumb consumers. To address this weak instrument problem, we propose a new instrument for endogenous disposable income growth in the consumption function, namely, the Greenbook forecast of real disposable income growth. We show that this instrument encompasses the information contained in the conventional set of instruments, and is a superior predictor of income growth. We find that using our proposed instrument ameliorates the weak instrument problem and provides a much smaller estimate for the rule-of-thumb consumers. We also extend our empirical framework to allow for habit persistence and provide an estimate for this important parameter of the consumption function. Finally, we use a time-varying specification of consumption function that allows for endogenous regressors, and document a decline in the share of rule-of-thumb consumers and a rise in the habit- persistence parameter in the U.S. over our sample period. We find that an increase in credit growth and supplementary income benefits are negatively correlated with share of rule-of-thumb consumers, whereas they are positively correlated with habit persistence parameter

Build your own closed loop: Graph-based proof of concept in closed loop for autonomous networks

Next Generation Networks (NGNs) are expected to handle heterogeneous technologies, services, verticals and devices of increasing complexity. It is essential to fathom an innovative approach to automatically and efficiently manage NGNs to deliver an adequate end-to-end Quality of Experience (QoE) while reducing operational expenses. An Autonomous Network (AN) using a closed loop can self-monitor, self-evaluate and self-heal, making it a potential solution for managing the NGN dynamically. This study describes the major results of building a closed-loop Proof of Concept (PoC) for various AN use cases organized by the International Telecommunication Union Focus Group on Autonomous Networks (ITU FG-AN). The scope of this PoC includes the representation of closed-loop use cases in a graph format, the development of evolution/exploration mechanisms to create new closed loops based on the graph representations, and the implementation of a reference orchestrator to demonstrate the parsing and validation of the closed loops. The main conclusions and future directions are summarized here, including observations and limitations of the PoC
