The Determinants of Equilibrium Unemployment

The paper takes the search and matching model of the aggregate labor market to the data. It tests the model's empirical validity and employs structural estimation to generate a characterization of the optimal behavior of firms and workers. The model is applied to Israeli data that are uniquely suited for this kind of empirical investigation. The structural estimates are used to quantify the frictions embodied in the model, including the costs of search, the congestion and trading externality effects, and the matching process. A calibration-simulation analysis then studies the effect of several key variables on equilibrium unemployment.
On the metallicity of open clusters - II. Spectroscopy

Context. Open clusters are an important tool for studying the chemical evolution of the Galactic disk. Metallicity estimates are available for about ten percent of the currently known open clusters. These metallicities are based on widely differing methods, however, which introduces unknown systematic effects. Aims. In a series of three papers, we investigate the current status of published metallicities for open clusters that were derived from a variety of photometric and spectroscopic methods. The current article focuses on spectroscopic methods. The aim is to compile a comprehensive set of clusters with the most reliable metallicities from high-resolution spectroscopic studies. This set of metallicities will be the basis for a calibration of metallicities from different methods. Methods. The literature was searched for [Fe/H] estimates of individual member stars of open clusters based on the analysis of high-resolution spectra. For comparison, we also compiled [Fe/H] estimates based on spectra with low and intermediate resolution. At medium and high resolution, we found that differences in the analysis methods have a stronger effect on the metallicity than that of quality differences in the observations. We retained only highly probable cluster members and introduced a restriction on atmospheric parameters. Results. We combined 641 individual metallicity values for 458 stars in 78 open clusters from 86 publications to form our final set of high-quality cluster metallicities. The photometric metallicities discussed in the first paper of this series are systematically lower than the spectroscopic ones by about 0.1 dex, and the differences show a scatter of about 0.2 dex. In a preliminary comparison of our spectroscopic sample with models of Galactic chemical evolution, none of the models predicts the observed radial metallicity gradient. Conclusions. Photometric metallicities show a large intrinsic dispersion, while the more accurate spectroscopic sample presented in this paper comprises fewer than half the number of clusters. Only a sophisticated combination of all available photometric and spectroscopic data will allow us to trace the metallicity distribution in the Galactic disk on a local and global scale.
Marine Bacteria As Source Of Pigment For Application As Dye In Textile Industry

The textile industry is one amongst the rapidly growing industries world wide, which utilizes enormous amounts of synthetic dyes. Consequently, the effluent from these textile industries poses serious threat to the environment which is often very difficult to treat and dispose. This has become a very grave problem in environment conservation and hence natural pigments have drawn the attention of industry as safe alternative. In this context, in the present study an attempt was made to bioprospect marine bacteria towards isolation of a suitable and ideal pigment that could be used as a natural dye. A marine Serratia sp. BTWJ8 was recognized to synthesize enormous amounts of a prodigiosin-like pigment. The pigment was isolated and characterized for various properties. The pigment was evaluated for application as a dye in the textile industry. Results of the studies indicated that this pigment could be used as a natural dye for imparting red-yellow colour to various grades of textile materials. The colour was observed to be stable after wash performance studies.
Effect of Irrigation Intervals, Nitrogen Sources and Nitrogen Levels on Some Characters of Parsley (Petroselinum crispum Mill )@@@تأثير فترات الري ومصادر ومستويات التسميد النيتروجينى على بعض صفات البقدونس

Two field experiments were carried out at the Agricultural Research Experiment Station, King Abdulaziz University, Hada Alsham, Saudi Arabia, during 2007 and 2008 seasons. The aim of this investigation was to study the effects of four irrigation intervals (2, 4, 6 and 8 days), two nitrogen sources (urea and ammonium sulphate), three nitrogen levels (0, 100 and 200 kg N ha), and their combination treatments on some vegetative growth and yield characters of parsley. The obtained results revealed significant effects of the three studied factors on vegetative growth and yield characters during the two seasons. Application of 2 days as irrigation interval, urea form as source of nitrogen and 200 kg N ha, produced the highest mean values of plant height (32.0 cm), number of branches/ plant (7.14), number of leaflets/ plant (18.41), fresh weight of plants/ m (2.852 kg) and fresh weight of 5 plants (53.74g).
Vietnam’s path to converging with international accounting standards

This research investigates Vietnam’s approach to converging with international accounting standards using a variety of de jure convergence scores between Vietnamese Accounting Standards (‘VAS’) and International Accounting Standards/International Financial Reporting Standards (‘IAS/IFRS’), such as full convergence, partial convergence and non-convergence. Vietnam’s initial approach to converging with IAS/IFRS is one of selecting suitable IAS/IFRS issues to fully adopt, but there are few VAS issues modified from IAS/IFRS. The level of convergence between VAS and their equivalent IAS/IFRS is quite high at the beginning (84%), then drops significantly to 63% in 2013 due to non-response to subsequent amendments to IAS and new IFRS. If Vietnam is to effectively compete in the world’s capital markets then a resurgence of the convergence program is urgently needed. If the International Accounting Standards Board (‘IASB’) is to achieve its global convergence goals, then it should consider the implications of IAS/IFRS convergence specific to emerging markets.
Effect of compaction of soil on the development and production of cowpea inoculated with rhizobium

Cowpea is considered as one of the most important species in Brazil, for presenting essential components to the feeding process, which makes it relevant to identify the physical, chemical and biological conditions that benefit or cause damage to its development. Thus, the objective of this study was to evaluate the effect of inoculation with rhizobia strains in compacted soil on the development and production of cowpea. The experiment was conducted in a greenhouse, in a completely randomized design with six replications, in a factorial 3 × 2, with two inoculation treatments (BR3267 - Bradyrhizobium sp. and the combination of the strains MT8 - Rhizobium tropici and MT15 - R. tropici) and a control with nitrogen fertilization - 150 mg dm-3, using urea as a source, in compacted and uncompacted soil. The evaluations were carried out during the crop cycle (35, 45, 52, 58 and 90 days) after the emergence of plants, determining the Falker chlorophyll content, dry mass of grains, nitrogen content, nitrogen accumulation and crude protein in shoots and grains. All data were subjected to statistical analyses using the SISVAR program, performing the analysis of variance and the Tukey test at the level of 5% probability. The results showed positive effect on plants inoculated with the combination of the strains MT8 + MT15 in compacted soil, in all parameters evaluated, being observed, values similar to or greater than in plants grown in uncompacted soil. Therefore, the use of the combination of strains becomes a promising alternative for the cowpea development in soil with a density of 1.6 Mg m-3. Key words: Biological nitrogen fixation, cerrado, soil density.
Semianalytical model for nonlinear absorption in strongly interacting Rydberg gases

Rate equation models are extensively used to describe the many-body states of laser driven atomic gases. We show that the properties of the rate equation model used to describe nonlinear optical effects arising in interacting Rydberg gases can be understood by considering the excitation of individual superatoms. From this we deduce a simple semianalytical model that accurately describes the Rydberg density and optical susceptibility for different dimensionalities. We identify the previously reported universal dependence of the susceptibility on the Rydberg excited fraction as an intrinsic property of the rate equation model that is rooted in one-body properties. Benchmarking against exact master equation calculations, we identify regimes in which the semianalytical model is particularly reliable. The performance of the model improves in the presence of dephasing which destroys higher-order atomic coherences.
Contribution of Resource-Based View and Entrepreneurial Orientation on Small Firm Growth

[EN] This research provides a useful framework for identifying a small firms’ propensity to engage in entrepreneurial orientation. We examine the impact of the Entrepreneurial Orientation (EO) as a main resource and capability on small firm’ growth. The growth seems to come out as an important demonstration of the entrepreneurial orientation of small firms (Davidsson, 1989; Green and Brown, 1997; Janney and Gregory, 2006). Thus, this research builds on prior conceptual research that suggests a positive integration between entrepreneurial orientation and resource-based view. In the first instance, the research will focus on reviewing literature in the emerging area of entrepreneurial orientation as it applies to growth oriented small firms and resource-based view of the firm. Secondly, an empirical study was developed based on a stratified sample of small firms of manufacturing industry. Data were submitted to a multivariate statistical analysis and a linear regression model was performed in order to predict the influence of the resources and capabilities on small firms’ growth. In this sense, we consider the construct growth as a dependent variable and the ones relates with resources and capabilities (entrepreneur resources, firm resources, networks and EO) as independent variables. The research results suggest a set of resources and capabilities that promote the growth of the small firms. Also, the EO seems to have a predictive value on growth. Explaining variables related with resources and capabilities and EO were identified as essential in growth oriented small firms. It was still possible to conclude that the entrepreneurial firms which grew seem to have resources and develop more capabilities and take advantage in the search for those competences. This attitude reflects on the EO of the firm. This study has important implication for both researchers and practitioners. It highlights the necessity of firms to develop superior EO of all their members and also to invest on better resources and consequently superior capabilities as a way of reaching higher levels of growth. While previous authors have attempted to analyse certain aspects of this process (linkage between entrepreneurial orientation and growth), this research developed a framework that combines these and others factors (resource-based view) pertinent to growth oriented small firms. The results support the necessity to identify explicative variables of multiple levels to explain the growth of small firms. The adoption of an entrepreneurial orientation as an indispensable variable to the growth oriented small firms seems pertinent.
The Determinants of Rising Inequality in Health Insurance and Wages, Second Version

Over the last 30 years in the U.S., less educated workers have experienced a sharp decline in health insurance coverage rate and stagnant wage growth. In contrast, more educated workers' health insurance coverage rate has stayed relatively stable and their wages have rapidly grown. This paper investigates the determinants of the increase in inequality in health insurance coverage and wages by estimating an overlapping generations equilibrium model of labor and health insurance markets' demand and supply. The estimated model is used to quantify the effects of changes in aggregate factors (including rising cost of medical care services, Medicaid eligibility expansion, skill-biased technological changes in the labor market, and changes in the labor force composition) on the inequality of health insurance coverage and wages. I find that the interaction between the rising cost of medical services and labor market technological change is the most important determinant of the widening gap of health insurance coverage.
Road infrastructure development and economic growth

Stimulating economic growth and development of road infrastructure in economical lagging regions is the goal of many countries. This is because road infrastructure plays a crucial role by providing mobility for the efficient movements of people and goods, as well as providing accessibility to a wide variety of commercial and social activities. However, to achieve a sustainable economic growth, focusing on road infrastructure development alone would not be sufficient. Thus, this study analyse the contribution of road infrastructure development and other socio-economic factors that contributed to economic growth. To shed light on this issue, fixed-effects panel linear regression analysis was conducted using time-series cross-sectional data for 60 countries over the period of 3 decades from 1980 to 2010. The key finding of this study demonstrated that the growth in road length per thousand population, per capita export, per capita education expenditure and physical capital stock per worker contributed positively to economic growth. It was observed that there is an inverted U-shaped dependency relationship between urbanization and economic growth. That is, the economic growth increases at low urbanization levels but decreases once urbanization exceeds a threshold level. Moreover, it was also observed that the growth in road length per thousand population would facilitate export growth. In summary, this study suggest that policies focused on road infrastructure development should be implemented hand-in hand with other socio-economic and urban growth policies, in order to realize a sustainable economic growth.
A Cross-Section Analysis of Intra-Industry Trade in the U.S. Processed Food and Beverage Sectors

This paper analyzes the determinants of variation across industries in levels of intra-industry trade (IIT) for a sample of thirty-six U.S. processed food and beverage industries in 1987, previous studies of intra-industry trade having focussed on industry characteristics in the manufacturing sectors. The determinants predicted by IIT theory are measures of product differentiation, economies of scale, and imperfect competition; the results of this analysis indicate that IIT variation across the food and beverage industries is positively related to product differentiation, economies of scope, and similarity of tariff barriers among trade partners, but negatively related to industry concentration.
Postharvest responses of cut Dendrobium orchids to exogenous ethylene

The time to senescence of flowers in Dendrobium hybrids is different and one of the major reasons for this variation in vase life can be related to differences in the level of ethylene sensitivity. This study was conducted to determine the sensitivity of six cut Dendrobium hybrids to exogenous ethylene. The cut orchid inflorescences were treated with or without 10 μL/L ethylene gas for 24 h, and then placed in bottles containing a standard vase solution. Water loss, vase life, anthocyanin contents and ethylene production were determined after the treatments. The results indicated that different hybrids showed distinct variances in ethylene sensitivities and degrees of deterioration. Dendrobium ‘Darren Glory’ and D. ‘Jaquelyne Concert’ × D. ‘Rinappa’ exhibited the utmost hyponasty, weight loss and degradation of anthocyanin content in sepals and petals. Thus, these two hybrids were categorized as the very sensitive group. On the other hand, D. ‘Sonia Red ’, D. ‘Shavin White’ , D. ‘Sonia White’ and D. ‘Sonia Bom ’ showed lower sensitivity and hence were categorized in the less sensitive group. The results of this experiment and similar experiments to determine the resistant and susceptible cultivars to ethylene injury can be helpful in improving the postharvest life of cut orchid flowers. Key words: Ethylene sensitivity, vase life, anthocyanin content, ACC synthase, ACC oxidase.
ORAL HYGIENE HABITS AND ITS ASSOCIATION WITH DENTAL CARIES AMONG CHILDREN AGED 8-12 YEAR IN LIBYAN SCHOOLS, KLANG VALLEY, MALAYSIA

ABSTRACT Background: Dental caries is a serious public health problem worldwide. Prevalence of dental caries among school children has increased in both developed and developing countries since the last few decades. The objective of this study was to determine the association of dental caries with oral hygiene habits among Libyan school children aged 8-12 years in Klang Valley, Malaysia. Methodology: A cross-sectional study was conducted in three Libyan primary schools in Klang Valley, Malaysia. Five hundred and seventy children aged 8-12 years participated. They were randomly selected using proportional stratified sampling method. Dental caries was assessed using the WHO (1987) criteria. Results: Response rate was 92.5% . The prevalence of dental caries was (55.8%), females have higher dental caries than males. Dental caries was found highly prevalent among; children their aged 10 years (64.7%), children whose father and mother have a job (58.5% and 58.7%) respectively, children whose father and mother have elementary level of education (69.6% and 61.0%) respectively, children who have poor oral hygiene (99.0%). Chi square test showed significant association of dental caries with age group, father’s education level and oral hygiene habits. Logistic regression analysis identified young age (OR=0.085, 95% Cl: 0.017-0.434) and poor oral hygiene (OR=0.001, 95% Cl: 0.00-0.009) were significant predictors of dental caries among children. Conclusions: Prevalence of dental caries is associated with oral hygiene habits of children in this study. Health education on good oral hygiene habits should be emphasized among younger Libyan school children. Keywords: Dental Caries, School Children, Oral Hygiene Habits.
Water relations and hydraulic characteristics of three woody species co-occurring in the same habitat

Trois especes ligneuses, typiquement en cours d'extension dans la region Karstique de Trieste (Italie du nord) i.e. Cotinus coggygria L. , Prunus mahaleb L. and Fraxinus ornus L. , ont ete suivies aux echelles journalieres et saisonnieres en termes de conductance foliaire pour la vapeur d'eau, de transpiration et de potentiel hydrique (Ψ L ). ainsi que de resistance hydraulique totale, tige et racinaire (R plant , R shoot and R root , respectivement) dans l'objectif d'analyser l'impact des parametres hydrauliques des plantes sur leur resistance au stress hydrique. F. ornus a montre la plus grande chute de Ψ L en Juillet et Septembre en raison de la grande valeur de R plant mesuree chez cette espece. Des relations positives et significatives ont ete trouvees entre R plant Υ L et R root pour les trois especes etudiees, ce qui suggere que les proprietes hydrauliques des racines sont un determinant majeur des proprietes hydrauliques de la plante et de leur resistance au stress hydrique. Les valeurs croissantes de R root (et R plant ) de C. coggygria a P. marialeb et F. ornus fournissent une explication possible pour la sequence temporelle d'expansion de ces trois especes dans les zones degradees.
The voice of nurse educators on teaching end of life care in U.S. schools of nursing

800x600 Background: End of life care (EOLC) education is important for those engaged in the caring professions. In 1997 the principal investigator (PI) for this study, working as a nurse educator, noted that there was no EOLC in the undergraduate program in her school of nursing, and she began to incorporate content into her teaching. She was not alone; over a decade ago it was identified by the American Association of Colleges of Nursing (AACN) that there were deficiencies in EOLC nursing education. AACN worked with the City of Hope National Medical Center to form the End of Life Nursing Education Consortium (ELNEC) to help address the pedagogic insufficiency. The PI was in the first ELNEC Trainer cohort in 2001 and has been to several other ELNEC conferences since then. The author’s experiences with the integration of EOLC education, along with ongoing commentary from other nurse educators at various conferences and seminars, prompted this study. Methods: This was an exploratory descriptive study in which nurse educators in U.S. schools of nursing were invited to participate in a survey to elicit information regarding the current state of end of life care (EOLC) education in their respective school programs. A survey was developed and after IRB approval was emailed in several phases to academic nursing programs throughout the United States. Among respondents who met inclusionary criteria for the survey, 233 completed the survey. Survey participants were anonymous and were also invited to provide commentary and recommendations. Analysis-synthesis of qualitative data was done to identify if there were any themes. Results: Two hundred and four participants responded to the question of whether they had been able to integrate EOLC content into their respective programs and 138 answered in the affirmative, although almost all of the participants, even those who claimed some success in the integration of EOLC content, shared having met with various obstacles. How much EOLC education was integrated and what was actually taught varied considerably. Significant barriers to EOLC education were identified by many respondents and recommendations for improvement were offered. Conclusions: Nurse educators need to champion EOLC education in schools of nursing to ensure that nurses today and tomorrow will be prepared to provide the quality care that society deserves.

The Effects of Animated Feedback on Locating Verbs in a Dynamic Contextual Scene Display on an Augmentative and Alternative Communication Device

Purpose: Technological advances in augmenta- tive and alternative communication (AAC) offer the poten- tial to enhance the communication needs of individuals with severe communication disorders. However, using AAC to express concepts that cannot be easily represented in static line drawings is a significant challenge. Animation of line-drawn action verbs represents a means to enhance the transparency of previous static representations and poten- tially make the representations easier for children to use. Method: A mixed group design with repeated measures was used to test the effect of animation used as feedback in locating and selecting action verbs in a visual scene on a dynamic AAC display. Twenty 3-year-old children without disabilities (10 boys and 10 girls) were quasirandomly as- signed to an animation or no-animation group. Participants' M
