This study investigates the psychometric characteristics of Gordon’s Advanced Measures of Music Audiation (AMMA) in a region with strong non-Western music tradition. It also examines the possibility of measuring audiation with the modern psychometric theory. The AMMA test was administered to 513 students in the city of Ioannina and a number of villages in the region of Epirus in northwestern Greece. Nonlinear factor analysis based on tetrachoric correlation coefficients confirmed a tone and rhythm structure in AMMA according to the theory of Gordon. Cronbach’s alpha coefficients for the tone and rhythm factor scores were .70 and .61 correspondingly. The Kuder and Richardson’s (KR-20) reliability coefficient for the 30 items was .55. A Rasch measurement model has a good fit. The analysis of the Rasch residuals has showed that the dimensions of AMMA do not distort the estimation of Rasch parameters. Further analysis of the 30 AMMA items has shown that they can be ordered in 10 levels of difficulty. The authors present items’ difficulty and persons’ level of audiation on the same interval scale and discuss the usefulness of the music ability tests that are based on aural stimuli.

Scale Properties

This study evaluated the psychometric properties of the Relative Mastery Scale (RMS). Valid and reliable client-centered instruments support practice in value-based health care and community-based settings. Participants were 368 community-dwelling adults aged 18 to 95 years. Researchers conducted validity and reliability examinations of the RMS using classical test theory and Rasch measurement model. A partial credit model allowed exploration of individual scale properties. Spearman’s correlation coefficients between items were statistically significant at the .01 level. Cronbach’s alpha coefficient was .94 showing strong internal consistency. In exploratory factor analysis, Factor 1 accounted for 71% of variance with an eigenvalue of 4.26. In Rasch analysis, the 5-point rating scale demonstrated adequate functioning, confirmed unidimensionality, and person/item separation. The RMS instrument demonstrates sound psychometric characteristics. A valid and reliable measure of internal occupational adaptation supports application to monitor progress of internal occupational adaptation across a variety of individuals.

The topic of metamemory had attracted the attention of many researchers and scholars in the field of educational and cognitive psychology, especially how individuals become aware of and control their memory functions. Therefore, the aim of the present study was to build a psychometric scale/questionnaire for measuring metamemory. The study was conducted among a sample of 200 students joining Sharia/Islamic Law, Arabic Language, Education, English Language, Science, Economics and Management at Al Qassim University. For the purpose of the content validity of the scale, it was verified by the raters’ agreement and the internal consistency of the items of the scale. Pearson correlation coefficient was also used to calculate correlation coefficients between the scores of each item and its dimension to ensure consistency and homogeneity of the items and dimensions of the scale. The correlation coefficients of the items of the scale and the total score of the dimension to which the items belong were all positive correlation coefficients and statistically significant at the level of 0.01, which confirms the consistency and homogeneity of the items of each dimension. The homogeneity of the dimensions of the scale was also verified by calculating Pearson correlation coefficients between the score of each dimension and the overall score of the scale. The reliability of the scale and its sub- dimensions was verified using the α- Cronbach Alpha coefficient. The results showed that the scale and its sub- dimensions had high and statistically acceptable validity and reliability coefficients. Such result indicates that the scale is statistically valid and reliable.

Food hypersensitivity is a reaction to the food consumed, regardless of the pathogenetic mechanisms that cause the symptoms. It is an actual and controversial problem in pediatric practice. Nowadays there is an active search for the causes of disease progression, a large role is given to the study of genetic and external factors (food, environmental, social). This disease arises many questions due to the similarity of the clinical representation in different kinds of food hypersensitivity and in different pathogenetic mechanisms, which are involved. The purpose of the study is to perform the analysis of factors, which cause appearance of food hypersensitivity in toddlers. Materials and methods. A study of the number of children with food intolerance was conducted using a specially compiled questionnaire. Thus, 4,500 questionnaires were distributed in pre-school and medical establishments to question parents. Results and discussion. Analysis of 3,214 questionnaires was conducted, which enabled to obtain information from parents on anamnesis and living conditions of toddlers. Values of 56 factors were analyzed, calculating correlation coefficients with a formation of food hypersensitivity for each of them. Statistical analysis allowed distinguishing 15 signs among these factors, which significantly correlated with the formation of food hypersensitivity in young children. The investigation enabled not only to detect factors that affect formation of food hypersensitivity in young children, but also to suggest a mathematical model of individual calculation of risk factors for this pathology. Data of conducted mathematical analysis can be used for elaboration of a complex of prophylaxis measures on development of food hypersensitivity in toddlers. Conclusion. The formation of hypersensitivity to cow's milk in children is provoked by the presence of contact reactions in the child, adverse reactions after medication, positive family history (bronchial asthma in relatives, skin diseases in parents (father and / or mother)), smoking in the family, living in the city; at the same time, preventive factors are living in an apartment, in a new building, in a dry apartment. The formation of food hypersensitivity in young children is generally provoked by a positive family history (bronchial asthma, hay fever, urticaria, diseases of the stomach and duodenum in relatives, skin diseases in parents), smoking in the family; frequent consumption of food in a mass catering points; living in the city plays a preventive role

The population of the city of Orеl consumes drinking underground water of Zadonsko-Optuhovsky and Voronezh-Livny aquifers with natural iron content, annual mean levels of which over the observation period from 2007 to 2015 exceeded the maximum allowable concentration (0.3 mg/l) by 1.03 to 1.43 times, with a maximum of 3.67 to 17.7 times. Although an elevated iron content in drinking water has been considered primarily in terms of organoleptic changes, several sanitary studies of recent years have revealed the prolonged use of water containing iron in concentrations, which exceed the maximum allowable ones, to scale up overall morbidity as well as the development of blood, skin and subcutaneous tissue diseases, musculoskeletal problems, digestive, urogenital system and allergic disorders. There are many reports concerning causes and the harm to human organism due to iron overload, and largely explanation of the possibility of developing the above types of pathology. The purpose of the study is to identify relationships between levels of total iron content in drinking water and the morbidity rate of the population of the city of Orel. Investigations were executed with the use a correlation analysis. For the period from 2007 to 2015, there were revealed direct correlation relationships between the annual average concentrations of iron in drinking water and the total morbidity rate of children and adults as well as 11 types of non-infectious pathologies, including diseases of the respiratory and urogenital system, atopic dermatitis, reactive arthropathies and eczema in children; diseases of blood and blood-forming organs, reactive arthropathies, gastritis and duodenitis in adolescents, stenocardia, cerebrovascular diseases, diabetes mellitus, gastritis, duodenitis and liver diseases in adults. The correlation coefficients amounted to from 0.66 to 0.86, with an accuracy of 0.01-0.05. These relationships may be causal in nature, as it was proved by similar results obtained in the Tula region, Primorsky Krai, and Sverdlovsk region where the population uses ground water with a high iron content. Apparently, it should be more careful in the assessment of the elevated iron content in drinking water from a hygienic viewpoint and must focus, among other things, on its possible causal relations with the morbidity rates of the population, rather than scrutinizing primarily its impact on the organoleptic water properties.

Music Tradition

Ethiopia upholds unique cultural heritage and diverse music history in entire African continent. The traditional music heritage of Ethiopia has been globally recognized with its distinct music culture and symbolic manifestation. The traditional songs and music of the country revolves around core chord of their life and culture. The modern music of Ethiopia has been blended with combination of elements from traditional Ethiopian music and western music which has created a new trend in the music world. The music tradition of the country not only maintains the cultural identity but also maintains social cohesion through cultural expression at different social occasions and resists cultural changes infused through globalization. The globalization has brought a series of transformation and changes in the world of Ethiopian music through commercialization, commodification and digitalization of cultural expressions apart from hijacking the cultural rights of traditional musicians. The younger generations have been attracted towards western music undermining the aesthetic and cultural value of music tradition of the country. The international enactments relating to protection and safeguarding of cultural rights of people are yet to be appropriately translated into reality. The emergence of culture industries and entertainment houses has posed serious threats to local culture and led to disappearance of local traditions, musical heritage and their replacement by popular global music. The cultural homogeneity and commodification has replaced the multiplicity of cultures in this globalized era. This paper based on review of published articles and content analysis critically unfolds sensitive areas of cultural shock and violation of cultural rights exposed to traditional musicians and traditional singers of Ethiopia during last couple of decades.Int.

The city of Bismarck, North Dakota has one of the highest numbers of West Nile Virus (WNV) cases per population in the U.S. Although the city conducts extensive mosquito surveillance, the mosquito abundance alone may not fully explain the occurrence of WNV. Here, we developed models to predict mosquito abundance and the number of WNV cases, independently, by statistically analyzing the most important climate and virus transmission factors. An analysis with the mosquito model indicated that the mosquito numbers increase during a warm and humid summer or after a severely cold winter. In addition, river flooding decreased the mosquito numbers. The number of WNV cases was best predicted by including the virus transmission rate, the mosquito numbers, and the mosquito feeding pattern. This virus transmission rate is a function of temperature and increases significantly above 20 °C. The correlation coefficients (r) were 0.910 with the mosquito-population model and 0.620 with the disease case model. Our findings confirmed the conclusions of other work on the importance of climatic variables in controlling the mosquito numbers and contributed new insights into disease dynamics, especially in relation to extreme flooding. It also suggested a new prevention strategy of initiating insecticides not only based on mosquito numbers but also 10-day forecasts of unusually hot weather.

Abstract. We present an intercomparison study of four airborne imaging DOAS instruments, dedicated to the retrieval and high-resolution mapping of tropospheric nitrogen dioxide (NO2) vertical column densities (VCDs). The AROMAPEX campaign took place in Berlin, Germany, in April 2016 with the primary objective to test and intercompare the performance of experimental airborne imagers. The imaging DOAS instruments were operated simultaneously from two manned aircraft, performing synchronised flights: APEX (VITO–BIRA-IASB) was operated from DLR's DO-228 D-CFFU aircraft at 6.2 km in altitude, while AirMAP (IUP-Bremen), SWING (BIRA-IASB), and SBI (TNO–TU Delft–KNMI) were operated from the FUB Cessna 207T D-EAFU at 3.1 km. Two synchronised flights took place on 21 April 2016. NO2 slant columns were retrieved by applying differential optical absorption spectroscopy (DOAS) in the visible wavelength region and converted to VCDs by the computation of appropriate air mass factors (AMFs). Finally, the NO2 VCDs were georeferenced and mapped at high spatial resolution. For the sake of harmonising the different data sets, efforts were made to agree on a common set of parameter settings, AMF look-up table, and gridding algorithm. The NO2 horizontal distribution, observed by the different DOAS imagers, shows very similar spatial patterns. The NO2 field is dominated by two large plumes related to industrial compounds, crossing the city from west to east. The major highways A100 and A113 are also identified as line sources of NO2. Retrieved NO2 VCDs range between 1×1015 molec cm−2 upwind of the city and 20×1015 molec cm−2 in the dominant plume, with a mean of 7.3±1.8×1015 molec cm−2 for the morning flight and between 1 and 23×1015 molec cm−2 with a mean of 6.0±1.4×1015 molec cm−2 for the afternoon flight. The mean NO2 VCD retrieval errors are in the range of 22 % to 36 % for all sensors. The four data sets are in good agreement with Pearson correlation coefficients better than 0.9, while the linear regression analyses show slopes close to unity and generally small intercepts.

Correlation coefficients for SO2, CO and suspended particles between four monitoring stations located in extreme NW, NE, SW and SE corners of Mexico City urban area are found to be significantly high. The air quality standard for SO2 (0.10 ppm) was exceeded more than 10% of the time in January 1976. SO2 concentrations as well as wind intensity at the same four stations were found to be log-normally distributed for the January data.  Space-time correlations between the different stations and at different time-intervals were also studied to establish the transport length scale of SO2 over the city.  A distinct peak of correlation at two-hour interval over the center west of city (Chapultepec Park) indicates a southward flow of contaminants along the foot hills of mountains to the west.
