Self Report Data

With reference to EJPA’s unique and broad scope, the current study analyzed the characteristics of the authors as well as the topics and research aims of the 69 empirical articles published in the years 2009–2010. Results revealed that more than one third of the articles were written by authors affiliated with more than one country. With reference to their research aims, an almost comparable number of articles (1) presented a new measure, (2) dealt with adaptations of measures, or (3) dealt with further research on existing measures. Analyses also revealed that most articles did not address any particular field of application. The second largest group was comprised of articles related to the clinical field, followed by the health-related field of application. The majority of all articles put their focus on investigating questionnaires or rating scales, and only a small number of articles investigated procedures classified as tests or properties of interviews. As to further characteristics of the method(s) used, a majority of EJPA contributions addressed self-report data. Results are discussed with reference to publication demands as well as the current and future challenges and demands of psychological assessment.

Sculpture is an artistic practice that involves material, three-dimensional, and generally static objects, whereas cinema produces immaterial, two-dimensional, kinetic images. These differences are the basis for a range of magical, mystical and phenomenological interactions between the two media. Sculptures are literally brought to life on the silver screen, while living people are turned into, or trapped inside, statuary. Sculpture motivates cinematic movement and film makes manifest the durational properties of sculptural space. This book will examine key sculptural motifs and cinematic sculpture in film history through seven chapters and an extensive reference gallery, dealing with the transformation skills of "cinemagician" Georges Méliès, the experimental art documentaries of Carl Theodor Dreyer and Henri Alekan, the statuary metaphors of modernist cinema, the mythological living statues of the peplum genre, and contemporary art practices in which film—as material and apparatus—is used as sculptural medium. The book’s broad scope and interdisciplinary approach is sure to interest scholars, amateurs and students alike.

CO2 is a harmful greenhouse gas, a product of chemical emissions, the combustion of fossil fuels and car exhausts, and it is a widely available source of carbon. The review considers various ways of hydrogenation of carbon dioxide into components of motor fuels - methanol, dimethyl ether, ethanol, hydrocarbons - in the presence of heterogeneous catalysts. At each route of conversion of CO2 (into oxygenates or hydrocarbons) the first stage is the formation of CO by the reverse water gas shift (rWGS) reaction, which must be taken into account when catalysts of process are choosing. The influence of chemical nature, specific surface area, particle size and interaction between catalyst components, as well as the method of its production on the CO2 conversion processes is analyzed. It is noted that the main active components of CO2 conversion into methanol are copper atoms and ions which interact with the oxide components of the catalyst. There is a positive effect of other metals oxides additives with strong basic centers on the surface on the activity of the traditional copper-zinc-aluminum oxide catalyst for the synthesis of methanol from the synthesis gas. The most active catalysts for the synthesis of DME from CO2 and H2 are bifunctional. These catalysts contain both a methanol synthesis catalyst and a dehydrating component, such as mesoporous zeolites with acid centers of weak and medium strength, evenly distributed on the surface. The synthesis of gasoline hydrocarbons (≥ C5) is carried out through the formation of CO or CH3OH and DME as intermediates on multifunctional catalysts, which also contain zeolites. Hydrogenation of CO2 into ethanol can be considered as an alternative to the synthesis of ethanol through the hydration of ethylene. High activation energy of carbon dioxide, harsh synthesis conditions as well as high selectivity for hydrocarbons, in particular methane remains the main problems. Further increase of selectivity and efficiency of carbon dioxide hydrogenation processes involves the use of nanocatalysts taking into account the mechanism of CO2 conversion reactions, development of methods for removing excess water as a by-product from the reaction zone and increasing catalyst stability over time.

Glycosylation Reaction

We have discovered a new mode of reactivity of 1-thiosugars in the presence of Cu(II) or Co(II) for a stereoselective <i>O</i>-glycosylation reaction. The process involves the use of a catalytic amount of Cu(acac)2 or Co(acac)2 and Ag2CO3 as an oxidant in α,α,α-trifluorotoluene (TFT). Moreover, this protocol turned out to have a broad scope, allowing to prepare a wide range of com-plex substituted <i>O</i>-glycoside esters in good to excellent yields with an exclusive β-selectivity. The late-stage modification of phar-maceuticals by this method was also demonstrated.

Broad Scope

Education is a process of learning and learning both in terms of knowledge and skills. From a number of sources that researchers studied, researchers can deduce from education and education administration with a broad scope. Education and education administration have the same goals and functions, namely achieving an educational goal that can benefit society and the nation. This education also serves to create intelligent students, noble character, good personality and skills that can be useful to help other communities. Educational administration and education are very related, because they are very dependent. Educational administration is all processes and joint activities that must be carried out by someone related to educational tasks. If an education without education administration is accompanied by it will not be achieved an educational goal that is good for the welfare of society. From every educational process there is a need for educational administration. The purpose of both is very clear. With this education, can improve human resources for the progress of a nation. As we know now there are still many obstacles that occur in some areas for the implementation of a learning process and learning, this is influenced by several factors. With these obstacles, a teacher must be able to provide education and education administration to all students. The science of education administration is very useful for the community and students. Administration is not only about finance but also about skills and bookkeeping and has goals in accordance with educational goals.

Oral Narration

The review is concerned with detailed analysis of I. Kargashin’s monograph on Russian poetic narrations in the 17th–21st centuries. Normally applied to the epic genre, the concept of skaz [oral narration, tale] is extrapolated by the scholar to describe lyrical poetry. Hence the broad scope of issues discussed in the book: how accurately can the term be applied to lyrical works, since poetry is anti-narrative in its ‘pure form’? How can one structure the subjective sphere of poems, given that a skaz recreates a consciousness other than that of the author, unlike in lyrical poetry, where the author and the hero are inseparable? Following the questions, the scholar identifies typological characteristics of the examined phenomenon (appropriation of another’s consciousness, realization of this consciousness through a colloquial monologue, and depiction of the subject’s speech in verse), uncovers the reasons for its emergence (including ‘emancipation’ of the hero and transition to the spoken word), and traces its history and development.
