The construction of self in relationships: narratives and references to mental states during picture-book reading interactions between mothers and children

Previous studies showed that mothers vary in the way in which they discuss past experiences with their children, since they can exhibit narrative (elaborative) or paradigmatic (repetitive) styles to different extents. Given this background, the aim of the present study was to analyze differences in the mothers’ use of narrative styles and mental state language (MSL), as a function of children’s age and gender. Thirty dyads consisting of mothers and their 4- to 6-year-old children were observed during a picture-book reading interaction. Maternal utterances were coded according to the categories described by Tessler and Nelson (1994), classifying each mother as Narrative or Paradigmatic. Eight categories of MSL were analyzed: perceptual, emotional (positive and negative), volitional, cognitive, communicative, and moral. The results confirmed the existence of the two maternal styles observed in the earlier studies. Importantly, we found that the mothers of younger children were more narrative than paradigmatic, whereas the opposite pattern occurred for the mothers of older children (they were more paradigmatic than narrative). As concerns MSL, the results indicated that the use of communicative terms was significantly more frequent for narrative than for paradigmatic mothers, and decreased linearly with children’s age. Lastly, the mothers of younger children referred their MSL more frequently to the book characters than to themselves or to the child. Taken together, these results support the idea that mothers adapt their narrative styles and MSL input to the growing abilities of their children, therefore contributing to the development of social understanding

The Financial Crisis, Labor Market Transitions and Earnings: A Gendered Panel Data Analysis for Serbia

While results are starting to emerge, not much is known yet about the dynamics of the labor markets of the former Eastern economies, especially in the context of the current Financial Crisis. Arguably, this is mainly due to paucity of (panel) data. By examining labor market transitions, earnings levels, and earnings growth and their correlates using a recent panel data set for Serbia, this paper combines both of these issues. Estimation of gross transition probabilities reveals that females are disadvantaged in the Serbian labor market in terms of moving out of the two undesirable states, unemployment and economic inactivity, relative to males during the first year of the financial crisis – though males are harder hit than females in terms of the levels of unemployment. In terms of earnings, the picture is reversed, with females being worse off in terms of the levels of earnings, while they have experienced somewhat smaller earnings decreases than males (though, owing to the gender earnings gap, from a much lower base). Multinomial logit estimations of employment, unemployment, and inactivity transitions and OLS regressions of earnings and earnings growth reveal substantial gender differences related to individual, job, and firm characteristics. The overall results therefore hint at both males and females being hit in terms of employment and earnings, though in different ways. Finally, the paper discusses policy implications and provides suggestions for further research.financial crisis, gender, labor market flows, transition probabilities, earnings growth, panel data, Serbia

The global growth of mutual funds

With few exceptions, mainly in Asia, mutual funds grew explosively in most countries around the world during the 1990s. Equity funds predominated in Anglo-American countries while bond funds predominated in most of Continental Europe, and in middle-income countries. Capital market development (reflecting investor confidence in market integrity, liquidity, and efficiency) and financial system orientation were the main determinants of mutual fund growth. Restrictions on competing products acted as a catalyst for the development of money market and (short-term) bond funds.Payment Systems&Infrastructure,Economic Theory&Research,Financial Intermediation,International Terrorism&Counterterrorism,Non Bank Financial Institutions,Economic Theory&Research,Financial Intermediation,Non Bank Financial Institutions,Infrastructure Finance,Infrastructure Finance

Distributed control for COFS 1

An overview is given of the work being done at NASA LaRC on developing the Control of Flexible Structures (COFS) 1 Flight Experiment Baseline Control Law. This control law currently evolving to a generic control system software package designed to supply many, but not all, guest investigators. A system simulator is also described. It is currently being developed for COFS-1 and will be used to develop the Baseline Control Law and to evaluate guest investigator control schemes. It will be available for use whether or not control schemes fall into the category of the Baseline Control Law. First, the hardware configuration for control experiments is described. This is followed by a description of the simulation software. Open-loop sinusoid excitation time histories are next presented both with and without a local controller for the Linear DC Motor (LDCM) actuators currently planned for the flight. The generic control law follows and algorithm processing requirements are cited for a nominal case of interest. Finally, a closed-loop simulation study is presented, and the state of the work is summarized in the concluding remarks

Optimal active vibration absorber: Design and experimental results

An optimal active vibration absorber can provide guaranteed closed-loop stability and control for large flexible space structures with collocated sensors/actuators. The active vibration absorber is a second-order dynamic system which is designed to suppress any unwanted structural vibration. This can be designed with minimum knowledge of the controlled system. Two methods for optimizing the active vibration absorber parameters are illustrated: minimum resonant amplitude and frequency matched active controllers. The Controls-Structures Interaction Phase-1 Evolutionary Model at NASA LaRC is used to demonstrate the effectiveness of the active vibration absorber for vibration suppression. Performance is compared numerically and experimentally using acceleration feedback

The Crisis Hits Home: Stress-Testing Households in Europe and Central Asia

The financial crisis and economic downturn threatens the welfare of more than 160 million people who are poor or are just above the poverty line in the economies of Eastern and Central Europe, the former Soviet Union, and Turkey. This note concerns the findings of recent World Bank analysis (Tiongson et al. 2010)1 that uses precrisis household data and aggregate macroeconomic outcomes in these countries to simulate the impact of the crisis on households—transmitted via credit market shocks, price shocks, and income shocks. The adverse effects are widespread, with both poor and nonpoor households being vulnerable. By 2010, for the region as a whole, it is estimated that some 11 million more people will be in poverty and more than 23 million additional people will find themselves just above the poverty line because of the crisis.financial cirsis, stress testing, household income, Europe, Central Asia, welfare, Soviet Union, Turkey, World Bank, shocks

Small and medium size enterprise financing in Eastern Europe

There is currently a large interest in understanding firms'access to finance, particularly in the financing of small- and medium-size enterprises (SMEs). But the financing patterns of SMEs across countries is not well understood. For example, little is known about the relative importance of equity, debt, and inter-firm financing for SMEs across countries. The authors use the Amadeus database, which includes financial information on over 97,000 private and publicly traded firms in 15 Eastern and Central European countries. The Amadeus database allows the authors the opportunity to provide a new analysis of the general financing patterns of private firms across a large sample of Eastern European countries. The summary statistics show that the size of the SME sector (as measured by the percentage of total employment) in Eastern European countries is smaller than in most developed economies. Although the authors find in almost every country in the sample a large number of SMEs as a percentage of total firms, the SMEs in Eastern Europe are generally small and hire few employees. However, SMEs seem to constitute the most dynamic sector of the Eastern European economies, relative to large firms. In general, the SME sector comprises relatively younger, more highly leveraged, and more profitable and faster growing firms. This suggests that a new type of firm is emerging in transition economies that is more market- and profit-oriented. But at the same time, these firms appear to have financial constraints that impede their access to long-term financing and ability to grow.Microfinance,Small and Medium Size Enterprises,Banks&Banking Reform,Small Scale Enterprise,Payment Systems&Infrastructure,Private Participation in Infrastructure,Small Scale Enterprise,Banks&Banking Reform,Economic Theory&Research,Microfinance

Computer optimization techniques for NASA Langley's CSI evolutionary model's real-time control system

The evolution and optimization of a real-time digital control system is presented. The control system is part of a testbed used to perform focused technology research on the interactions of spacecraft platform and instrument controllers with the flexible-body dynamics of the platform and platform appendages. The control system consists of Computer Automated Measurement and Control (CAMAC) standard data acquisition equipment interfaced to a workstation computer. The goal of this work is to optimize the control system's performance to support controls research using controllers with up to 50 states and frame rates above 200 Hz. The original system could support a 16-state controller operating at a rate of 150 Hz. By using simple yet effective software improvements, Input/Output (I/O) latencies and contention problems are reduced or eliminated in the control system. The final configuration can support a 16-state controller operating at 475 Hz. Effectively the control system's performance was increased by a factor of 3

A velocity command stepper motor for CSI application

The application of linear force actuators for vibration suppression of flexible structures has received much attention in recent years. A linear force actuator consists of a movable mass that is restrained such that its motion is linear. By application of a force to the mass, an equal and opposite reaction force can be applied to a structure. The use of an industrial linear stepper motor as a reaction mass actuator is described. With the linear stepper motor mounted on a simple test beam and the NASA Mini-Mast, output feedback of acceleration or displacement are used to augment the structural damping of the test articles. Significant increases in damping were obtained for both the test beam and the Mini-Mast
