Yearly Data

Income and price elasticities of demand for coniferous and nonconiferous sawn wood, plywood, particle board, and fibreboard were estimated using yearly data from 43 countries, over the period 1963–1973. A static and a dynamic model were estimated by analysis of covariance and generalized least squares. The simpler technique, analysis of covariance, gave satisfactory estimates for both models. Demand for all products was found to be price inelastic, with long-term elasticities ranging from −0.1 for particle board to −0.2 for coniferous sawn wood. Price elasticities for plywood and nonconiferous sawn wood were not significantly different from zero but this result might only reflect price-data inadequacies. Long-term income elasticities were +0.7 and +0.5 for coniferous and nonconiferous sawn wood, respectively. Demand for all wood-based panels was income elastic, with long-term elasticities of +1.0 for plywood and fibreboard, and of +2.3 for particle board. The results indicated that in discussing elasticities of demand for forest products, the length of the time period should be specified. Full adjustment of demand to changing prices and income was shown to always take more than 1 year. Demand for fibreboard appeared to adjust most rapidly to changes in economic conditions; the demand for nonconiferous sawnwood adjusted most slowly.

Income And Price Elasticities

The purpose of this paper was to test if there had been systematic changes in the income and price elasticities of demand for forest products after the first oil embargo of 1973. The test used pooled data from 10 OECD (Organization for Economic Cooperation and Development) countries between 1961 and 1981. Eight commodity groups were considered: coniferous sawn wood, nonconiferous sawn wood, plywood, particleboard, fibreboard, newsprint, other printing and writing paper, and other paper and paperboard. The demand models used were distributed lags on first logarithmic differences of income and price in each country and year. The hypothesis that the long-term elasticities of demand with respect to gross domestic product were the same from 1963 to 1981 as from 1974 to 1981 was rejected for coniferous sawn wood and printing and writing paper. Long-term price elasticities had also changed for the same commodities. A negative trend in the demand of coniferous sawn wood and particleboard, independent of prices or gross domestic product, appeared to have set in after 1973.

Income And Price Elasticities

<p>Foreign trade policies applied to achieve economic growth and structural changes in the economies have an important role. The applications of these policies to determination of the direction, composition, and volume of exports and imports have affected on the price and income elasticities of exported and imported goods. Therefore, the export and the import policies must be analyzed with regards to the price and income elasticities. Considering the studies done so far, econometric analysis of supply and demand functions of export and import are generally seen analyzed based on a single equation model. Also simultaneous relationship between the supply and demand is mostly ignored. For this reason, the major aim of this study is to examine the simultaneous relationship between the supply and demand functions of export and import of manufacturing industry by using Two Stage Least Squares Method. According to results of estimation income and price elasticities for supply and demand of import are found compatible with the theory. Both in export and import demand equation of manufacturing, income and price elasticities are found positive and negative respectively. And also export and import supply elasticities for manufacturing are compatible with the theoretical expectations.</p><p> </p><p><strong>Özet</strong></p><p><strong></strong>Ekonominin büyümesi ve yapısal değişiminde, dış ticaret politikalarının önemli bir yeri vardır.

Abstract. The concept of emotional intelligence (EI) has attracted growing interest from researchers working in various fields. The present study examined the long-term stability (32 months) of EI-related abilities over the course of a major life transition (the transition from high school to university). During the first week of full-time study, a large group of undergraduates completed the EQ-i:Short; 32 months later a random subset of these students (N = 238), who had started their postsecondary education within 24 months of graduating from high school, completed the measures for a second time. The study found EI scores to be relatively stable over the 32-month time period. EI scores were also found to be significantly higher at Time 2; the overall pattern of change in EI-levels was more than can be attributed to the increased age of the participants.

Moisture Variation

Many forest products companies in the southeastern United States store large volumes of roundwood under wet storage. Log quality depends on maintaining a high and constant wood moisture content; however, limited knowledge exists regarding moisture variation within individual logs, and within wet decks as a whole, making it impossible to recommend appropriate water application strategies. To better understand moisture variation within a wet deck, time domain reflectometry (TDR) was used to monitor the moisture variation of 30 southern pine logs over an 11-week period for a wet deck at the International Paper McBean woodyard. Three 125 mm long TDR probes were inserted into each log (before the deck was built) at 3, 4.5, and 7.5 m from the butt. The position of each log within the stack was also recorded. Mixed-effects analysis of variance (ANOVA) was used to examine moisture variation over the study period. Moisture content varied within the log, while position within the stack was generally not significant. The performance of the TDR probes was consistent throughout the study, indicating that they would be suitable for long term (e.g., 12 months) monitoring.

Abstract Sociolinguistics and discourse analysis provide tools through which to examine how friendship is socially constructed through language and communication. Research on social isolation and loneliness reveals the importance of social interaction on the psychological and physical health of older adults. Given that linguistic, communicative, and functional abilities decline as dementia progresses, it is challenging to identify markers of friendship. The Friendship Project is an ethnographic study of social interaction among persons with dementia living in a long-term care setting. The data are from transcripts and field-notes of social interactions among residents with a range of cognitive impairments over a six-month time period. Results reveal that persons with dementia employ specific linguistic features such as narrative, evaluation, evidentials, and pronominal reference to make meaning and create relationships over time. Practical implications will be discussed.

Mathematical Process

The contribution of concrete to the tensile stiffness (tension stiffening) of a reinforced concrete (RC) member is a key governing factor for structural serviceability analyses. However, among the current tension stiffening models, few consider the effect brought forth by concrete shrinkage, and none studies take account of the effect for very long-term shrinkage. The present work intends to tackle this exact issue by testing multiple RC tensile elements (with different bar diameters and reinforcement ratios) after a five-year shrinking time period. The experimental deformative and tension stiffening responses were subjected to a mathematical process of shrinkage removal aimed at assessing its effect on the former. The results showed shrinkage distinctly lowered the cracking load of the RC members and caused an apparent tension stiffening reduction. Furthermore, both of these effects were exacerbated in the members with higher reinforcement ratios. The experimental and shrinkage-free behaviors of the RC elements were finally compared to the values predicted by the CEB-fib Model Code 2010 and the Euro Code 2. Interestingly, as a consequence of the long-term shrinkage, the codes expressed a smaller relative error when compared to the shrinkage-free curves versus the experimental ones.

Abstract Communication and interactions are an integral part of care in long-term care settings. Resident variables, such as race and gender, shape communication and interaction between staff and residents. The Quality of Interactions Schedule (QuIS) was developed to measure the quality of verbal and nonverbal interactions among nursing staff and older adults initially for those in acute care and later used as well in a variety of long term care settings. A quantified measurement of the quality of interactions between residents and staff was created to quantify the QuIS. The purpose of this study was to describe the gender and racial differences in scored quality of interactions. Data for the present study was based on baseline data from the Evidence Integration Triangle for Behavioral and Psychological Symptoms of Dementia (EIT-4-BPSD) implementation study. A total of 535 residents from 55 settings were included in the analyses. An analysis of covariance was conducted to determine a difference in QuIS scores between males and females while controlling for age. The second model tested for differences in QuIS scores between blacks and whites while controlling for age and gender. There was not a statistically significant difference in QuIS scores between male and female residents. There was a significant difference in QuIS scores between those who were black versus white, such that those who were black received more positive interactions from staff than those who were white. Future work should focus on a deeper examination of resident factors and staff factors that may influence these interactions.

Distribution Theorem

Consider any discrete time sequence of investment fortunes Fn which has a finite long-run growth rate [Formula: see text] when subject to the present value capital drawdown constraint Fne-rn ≥ λ* max 0≤k≤nFke-rk, where 0 ≤ λ* < 1, in the presence of a riskless asset affording a return of er dollars per time period per dollar invested. We show that money can be withdrawn for consumption from the invested capital without either reducing the long-run growth rate of such capital or violating the drawdown constraint for our capital sequence, while simultaneously increasing the amount of capital withdrawn for consumption at the identical long-term rate of V(r, λ*). We extend this result to an exponentially increasing number of consumption categories and discuss how additional yearly contributions can temporarily augment the total capital under management. In addition, we assess the short-term practicality of creating such an endowment/consumption/distribution program.

PurposeThis study examines the long term effects of macroeconomic fundamentals on apartment price dynamics in major metropolitan areas in Sweden and Germany.Design/methodology/approachThe main approach is panel cointegration analysis that allows to overcome certain data restrictions such as spatial heterogeneity, cross-sectional dependence, and non-stationary, but cointegrated data. The Swedish dataset includes three cities over a period of 23 years, while the German dataset includes seven cities for 29 years. Analysis of apartment price dynamics include population, disposable income, mortgage interest rate, and apartment stock as underlying macroeconomic variables in the model.FindingsThe empirical results indicate that apartment prices react more strongly on changes in fundamental factors in major Swedish cities than in German ones despite quite similar development of these macroeconomic variables in the long run in both countries. On one hand, overreactions in apartment price dynamics might be considered as the evidence of the price bubble building in Sweden. On the other hand, these two countries differ in institutional arrangements of the housing markets, and these differences might contribute to the size of apartment price elasticities from changes in fundamentals. These arrangements include various banking sector policies, such as mortgage financing and valuation approaches, as well as different government regulations of the housing market as, for example, rent control.Originality/valueIn distinction to the previous studies carried out on Swedish and German data for single-family houses, this study focuses on the apartment segment of the market and examines apartment price elasticities from a long term perspective. In addition, the results from this study highlight the differences between the two countries at the city level in an integrated long run equilibrium framework.
