A new approach for content-based image retrieval for medical applications using low-level image descriptors

Content based image retrieval (CBIR) has become an important factor in medical imaging research and is obtaining a great success. More applications still need to be developed to get more powerful systems for better image similarity matching, and as a result getting better image retrieval systems. This research focuses on implementing low-level descriptors to maximize the quality of the retrieval of medical images. Such a research is supposed to set a better result in terms of image similarity matching. In this research a system that uses low-level descriptors is introduced. Three descriptors have been developed and applied in an attempt to increase the accuracy of image matching. The final results showed a qualified system in medical images retrieval specially that the low-level image descriptors have not been used yet in the image similarity matching in the medical field

Job Analysis and HRM Strategic Decisions: Administrators’ Ethics as Moderating Variable

Job analysis has been identified as a critical issue in human resource management (HRM); little research has focused on the relationship of work-related ethics between JA (JA) and HRM strategic decisions. This study aims to determine the effect of JA on human resource management strategic decisions at Jordanian institutions of higher education. We also examine how the impact of JA varies depending on how prevalent administrators work-related ethics are in each institution. The studys sample includes (420) individuals who work in supervisory academic and administrative roles at four universities. We test our proposed model in both public and private universities in Jordans northern region, using structural equation modeling (SEM) to analyze the data. According to the findings, JA positively impacts HRM strategic decisions. On the other hand, administrators work-related ethics considerably moderate the influence of JA. Theoretical and practical implications are discussed

Buccal dental microwear and stable isotopes of El Collado: A mesolithic site from Spain

This study examines the correlation between buccal dental microwear and stable isotopes. The buccal surface of post-canine teeth casts from El Collado, the largest Mesolithic site in Spain, were examined under Scanning Electron Microscope; photomicrographs were taken from the middle third of the buccal surface with magnification 100X. Only six individuals passed the criteria for buccal dental microwear analysis. The photomicrographs were treated by adobe Photoshop 8.01 to cover an area 0.56 mm² of middle third of buccal surface, the output photomicrographs were digitized using Sigmascan Pro 5 by SPSS. Then the correlation between buccal microwear pattern and stable isotopes of the same individuals, of the previous study of Guixe et al., 2006, was examined using a Pearson test. Statistical analysis revealed that there is no significant correlation between stable isotopes and buccal dental microwear of the people of the Mesolithic site of El Collado. The historical and archaeological documentation suggest that the Mesolithic people tended to consume marine food. Fish-drying techniques were used during the Mesolithic period which allowed the introduction of dust and sand to the fish. These abrasive particles affected the buccal dental microwear pattern, so that no correlation between the isotopes and microwear may be expected. This also suggests that the buccal dental microwear pattern exceeds dietary reconstruction to reconstruct food processing techniques

Does export composition matter for economic growth in the United Arab Emirates?

This paper examines the export diversification process and the causality between disaggregated manufactured exports and economic growth in the United Arab Emirates (UAE). The study develops a model whereby domestic investments, gross domestic product, as well as disaggregated manufactured exports and imports of goods and services, are considered. The results show that chemicals and related products cause short-run economic growth, while a bi-directional causality exists between machinery and transport equipment exports and economic growth both in the short and long run. Therefore, the shift to machinery and transport equipment exports contributes to long-run, sustainable economic growth in the UAE

Does Financial Development Induce Economic Growth in UAE? The Role of Capitalization and Foreign Direct Investment

This paper examines the association between financial progress and economic growth in the United Arab Emirates over the period 1975Q1-2012Q4. We have employed Bayer-Hanck (2013) combined non-cointegration to test the long run relationship. Our analysis revealed the existence of cointegration between financial development and economic growth. It also revealed that capitalization and FDI stimulate economic growth. The findings suggest that proper use of FDI and financial policy redesign will sustain economic growth in long term. Keywords: Financial Development, FDI, Capital investment, Growth, UAE.

Rate of enamel formation and hypoplasia timing

Linear Enamel Hypoplasia (LEH) is a decrease in enamel thickness resulting from a temporary disruption in enamel formation during times of dental development. To establish a statistical relationship between the timing of enamel formation and the length of the crown, the published data of Reid and Dean (2006) were statistically analyzed using SPSS. The results indicate that the relationship between the crown length and the days of enamel formation is nonlinear as proposed by previous studies but exponential taking the form of , where y is the time of enamel formation in days, a and b are constants, and x is the crown length. Based on this equation, the timing of hypoplasia can be estimated more accurately using x as the distance of hypoplasia from the cemento enamel junction (CEJ). This study introduces a new equation for estimating the period of stunt growth (number of days of a hypoplastic event) depending on the horizontal shift of the mathematical function that represents the above relationship. This period may classify the LEH either as caused by acute growth disruptions or chronic and prolonged ones
