Re-entrant-Groove-Assisted VLS Growth of Boron Carbide Five-Fold Twinned Nanowires

引用

Chinese Physics Letters 2009年第8期26卷 230-233页

作者：付新蒋军刘超喻志阳 Steffan lea 袁俊 Laboratory of Advanced Materials Department of Materials Science and Engineering Tsinghua University Beijing 100084 Beijing National Center for Electron Microscopy Tsinghua University Beijing 100084 Department of Physics University of York York YOIO 5DD U.K.

We report a preferential growth of boron carbide nanowires with a five-fold twinned internal structure. The nanowires are found to grow catalytically via iron boron nanoparticles, but unusually the catalytic particle is in contact with the low-energy surfaces of boron carbide with V-shaped contact lines. We propose that this catalytical growth may be caused by preferential nucleation at the re-entrant grooves due to the twinning planes, followed by rapid spreading of atomic steps. This is consistent with the observed temperature dependence of the five-fold twinned nanowire growth.

Controlling and Corporate Social Responsibility： A Comparative Study of German and Estonian Controlling

引用

Chinese Business Review 2011年第9期10卷 768-782页

作者： lea Roostalu Siret Pihelgas Estonian Business School Tallinn Estonia Mainor Business School Tallinn Estonia

This paper focuses on the functions of controlling in Estonia and Germany, The analysis based on the study carried out in Estonian enterprises in 2008. The study was conducted by the Estonian work group of the International Controller Association ICV （internationaler controller verein）. The methodology and controlling questionnaire were the same, which were used by the German work group of ICV in 2006. The mentioned questionnaire was also worked out in Germany by Otto Beisheim School of Management. The authors compared the results of both studies Cultural differences and their impact on the tasks of controllers were also scrutinized. The results of the research indicate that the tasks of Estonian controllers are strictly fixed with procedure documents, which leaves very lithe room lbr independence and initiative. Usually, they are not involved in the strategic planning and goal setting. The final conclusion is that the sustainability function of controlling is much more on the background compared to other functions of controlling, but in the future the role of this function is expected to increase

The Collapse of Semi-Legal Institutions Among Ethiopian Immigrants in Israel and Their Impact on Intimate Partner Femicide in the Community

Ideology and Poetics in the Estonian Translations of Nikolai Leskov

引用

Sociology Study 2016年第5期6卷 312-319页

作者： Ljubov Kisseljova lea Pild University of Tartu Tartu Estonia

This paper brings up the issue of a systemic study of the translation of Russian classics into Estonian during the Soviet period. These translations are often considered to be only the result of the ＂Sovietization＂ of Estonian culture, but such approach is a simplification. Estonian translations of the Russian classics in the Soviet period, undoubtedly, depended on ideological conditions, but, it is argued here, were to a great extent determined by the mechanisms of cultural self-regulation and displayed continuity with translation strategies that had been established before the occupation, in the 1920s-1930s. In the independent Estonian Republic, a remarkable tradition of the translations of Russian classics existed thanks to the activity of A. H. Tammsaare, F. Tuglas, A. Oras, H. Talvik, B. Alver et al. Estonian translators devoted the particular attention to the text＇s audience--the Estonian readers. The paper explains why in the mid 19S0s Leskov, an ambivalent and diffficult-to-translate writer, was chosen by O. Samma and F. Kylli for the first presentation to the Estonian readers.

Management Accounting Problems and Perspectives in the Local Government of Estonia： An Analysis From the Viewpoint of Parsons＇ Paradigm

引用

Journal of Modern Accounting and Auditing 2013年第1期9卷 20-36页

作者： Tarmo Kadak lea Roostalu Tallinn University of Technology Tallinn Estonia Tallinn City Office Tallinn Estonia Estonian Business School Tallinn Estonia Tallinn City Office Tallinn Estonia

This case study focuses on the current and future needs of the management accounting within the Tallinn city government and their potential relationships with the sustainability reporting. This analysis is based on the study carried out within the city organizations in 2011. The questionnaire drawn up by the authors includes several questions about the current management accounting tools of the city and their development and support needs. The authors also add some questions related to the sustainability reporting, which is obligatory for the city as one of the members of the Aalborg Charter. The quantitative methodology was used. The authors＇ conclusion is that the level of the managerial accountability of the Estonian municipality is increasing and its sole economic focus is changing to a broader perspective. According to the findings of the study, the authors argue that both management accounting principles and sustainability principles are coming closer together. By using Talcott Parsons＇ adaptation, goal attainment, integration, and latency （AGIL） paradigm, the authors point out four critical components for implementing the sustainability reporting into a management accounting system. The results of this study highlight the role of values in the management accounting development, which is in harmony with the AGIL paradigm.

Older Adults’ Explanatory Models of High Blood Pressure

引用

Health 2016年第7期8卷 680-693页

作者： Margo-lea Hurwicz Margaret Rose Department of Sociology Gerontology & Gender University of Missouri-St. Louis St. Louis MO USA

Shared Explanatory Models (EM) of High Blood Pressure (HBP)/Hypertension (HTN) were explored using systematic data collection and analysis methods from cognitive anthropology. Older adults who were members of a Medicare HMO in Los Angeles were asked to list all the illnesses experienced by older adults that they could recall, and those listing HBP or HTN were asked to further list and discuss its symptoms, causes, treatments and prevention. Responses were tape recorded, transcribed, and analyzed to develop a systematic “sentence completion by card sort” follow-up procedure. Consensus Analysis (CA) of the systematically collected data identified shared EM for HBP/HTN. The model presented here is similar to models of HBP/HTN described by researchers working with patients from different regions and different ethnic groups, suggesting that there is a widely shared lay or popular model for this disease. Stress, lifestyle (diet, exercise, weight, and substance use), heredity and aging are thought to be the major causes of HBP/HTN. Physicians are thought to be the appropriate source of care, as HTN/HBP is serious, life threatening, and potentially disabling. The study of cultural understandings and shared EM of disease has direct relevance for clinical practice and public health education. For a disease such as HTN/HBP, knowing where and how such explanations differ systematically between patients and clinicians, and what impact this may have on patterns of adherence to prescribed treatment is a crucial area of concern.

Experimental and Theoretical Considerations of Electrolyte Conductivity in Glucose Alkaline Fuel Cell

引用

Circuits and Systems 2012年第1期3卷 111-117页

作者： lea Mor Zeev Rubin 不详

The paper focuses on the conductivity of the fuel cell electrolyte in a membraneless glucose-fueled alkaline fuel cell. The electrolyte conductivity is interpreted using simple physical models, considering either the empirical behavior of the solution’s viscosity, or the consideration of ions and molecules colliding in solutions. The conductivity is expressed as a function of KOH and glucose concentrations. The physical properties of the species (i.e. radii, thermal velocity) and the chemical equilibrium constant of the reaction that glucose undergoes in an alkaline solution can be estimate by comparing the experimental results with the theory.
