Culture as Politics: A Note on Language Legislation in Putin’s Russia
Authors: Lunde Ingunn
Published: September 2017

One of the goals of this volume, and of the conference that led to its compilation, is to point at the significance of our fields, to show the world in what ways languages — and modern language studies — are important, to demonstrate that language, history, culture, literature — and knowledge about these topics — are essential to society. Now, there is a range of possible answers to the question “important to whom?” In this article, I discuss the ways in which culture in general, and language in particular, has become an important field of attention to the authorities in today’s Russia, and for a particular purpose. Over the last decade, Russian authorities have significantly increased their involvement in the cultural field, creating programmes for the patriotic education of citizens, adopting new laws and regulations affecting film, literature and art, and exploring the capital of culture for all it is worth. It is important to get a firm grasp of the state’s renewed interest in culture, in order to assess its impact in the broader context of Russian politics and society. In the following, I discuss a few concrete examples of state involvement in the cultural sphere, focusing in particular on the question of language legislation.
Why Regional Prosodic Variation is Worth Studying: An Example from Russian
Authors: Post Margie
Published: September 2017

Being philologists, we teach foreign language students how to read properly: they learn the cultural and social context that is necessary to interpret utterances in another language. A good student learns to listen carefully as wel, since much information is provided by the way utterances are pronounced. The prosodic features of speech — e.g. stress, rhythm and intonation — carry both linguistic and non-linguistic, including social, meanings: an “accent” triggers stereotypes that are associated with a certain social group or region. In Danish, a language with little regional variability, prosodic differences are a vital cue to dialect discrimination. Does the same account for Russian? A project is planned to study objectively measurable (prosodic and other) regional differences in regionally coloured Russian urban speech, as well as their social meaning: Do Russians pay attention to them? And what are the social consequences of having a regional “accent” in a country with a strong standard language ideology?
Chronotopes in Patrick Modiano’s Fictional Writing of History
Authors: Holm Helge Vidar
Published: September 2017

The historic heritage that precedes our lives chronologically, such as the experiences of French Jews during the German occupation of their country in World War II, is of fundamental importance to the authorship of Patrick Modiano, born in 1945.  Whereas most of his other novels have clearly autobiographical references,  Dora Bruder (1997) has a place of its own among Modiano’s novels.  In Dora Bruder, the author tries to track the life experiences of a young Jewish girl during the Nazi Occupation of Paris.  Buildings, streets and various topoi in Paris and France becomes related to certain experiences of time (chronos) in a narration where Michail Bakhtin’s theories of the chronotope provide an interesting approach to discussing Modiano’s unique form of recreating a traumatic past through fiction.

Published: September 2017

Alkali-activated aluminosilicate cements, as a sustainable and high-performance class of cementitious materials, can benefit from the development of admixtures that can enhance various aspects of their performance. Alkali activation generally occurs at a faster pace than the hydration of Portland cement (PC). In this investigation, citric acid was evaluated as an admixture for controlling the hydration kinetics, enhancing the fresh-mix rheology and delaying the setting of alkali aluminosilicate cement (AAC) without compromising its long-term strength. The obtained experimental results showed that the use of 3 wt% citric acid reduced the heat of hydration, improved the fresh-mix rheology and increased the hardened material compressive strength of the AAC. The results demonstrate the merits of using citric acid as an effective admixture in alkali-activated cement to make it more compatible with the construction practices established for PC.

The paper presents outcomes of a research on social relationships of teenagers with and without experience of living in families.The research particularly focused on difficulties with socialization and causes of behaviour disorders in adolescents going into foster families.The paper describes the factors interfering with the formation of positive social relationships between adolescents and families.The outcomes of the research also contribute to the implementation of the 2017–2020 National Action Plan for Children as they are of much use to social services rendering assistance to vulnerable groups (adolescents and their families).Understanding the specifics of social relationships in orphan teenagers living in families with different incomes is important for specialists working with orphan children and children without parental care.The research outcomes may as well be used by specialists supporting foster families, tutors, teachers working in institutions for orphans and children without parental care, and by foster parents themselves.Besides, the obtained data may contribute to the establishment of a theoretical foundation of upbringing that would help minimize negative aspects in adaptation of orphan children; assist them in getting more prepared for life in foster families; provide careful support to children and families during adaptation; and help future foster parents accept their future child.
Nanosized Liposomes Containing Bile Salt: A Vesicular Nanocarrier for Enhancing Oral Bioavailability of BCS Class III Drug
Authors: Arafat Mosab , Kirchhoefer Cathrin , Mikov Momir , Sarfraz Muhammad , Löbenberg Raimar
Published: September 2017

PURPOSE: Liposomes have been studied as a colloidal carrier in drug delivery systems, especially for oral administration. However, their low structural integrity in the gut is still a major shortcoming. Membrane disruptive effects of physiological bile salts in the small intestine result in premature drug release prior to intestinal absorption. Thus, we analyzed the stabilizing effect of sodium deoxycholate when incorporated into nano-sized liposomes. METHOD: Cefotaxime-loaded liposomes were prepared with different sodium deoxycholate concentrations (3.75- 30 mM) by rotary film evaporation followed by nano-size reduction. The physical integrity of liposomes was evaluated by monitoring cefotaxime leakage, particle sizes in different simulated physiological media. The oral bioavailability and pharmacokinetics of cefotaxime was assessed in rats (n = 6 per group) after single dose of drug-encapsulated in liposomes containing bile salt, drug in conventional liposomes, and cefotaxime solution (oral and intravenous). RESULTS: Simulated gastric fluid with low pH showed less effect on the stability of liposomes in comparison to media containing physiological bile salts.  Liposomes containing 15 mM sodium deoxycholate were most stable in size and retained the majority of encapsulated cefotaxime even in fed state of simulated intestinal fluid being the most destructive media. Pharmacokinetics data showed an increase in Cmax and AUC0-inf in the following order: cefotaxime solution < conventional liposomes < liposomes made with bile salts. The total oral bioavailability of cefotaxime in liposomes containing bile salt was found to be 5-times higher compared to cefotaxime solution and twice as much as in conventional liposomes. CONCLUSION: Incorporation of bile salts, initially used as membrane permeation enhancer, also acted as a stabilizer against physiological bile salts. The nano-sized liposomes containing sodium deoxycholate were able to reduce the leakage of encapsulated cefotaxime in the gut due to the improved vesicle stability and to enhance the oral bioavailability of acid-labile drugs up to 5-fold. This article is open to POST-PUBLICATION REVIEW.

Authors: Manyibe Edward O. , Moore Corey L. , Wang Ningning , Davis Dytisha , Aref Fariborz , Washington Andre L. , Johnson Jean , Eugene-Cross Kenyotta , Muhammad Atashia , Lewis Allen
Published: September 2017

Purpose: This study examined and documented minority disability and health research leaders’ experiences and perspectives on career development challenges and success strategies. Methods: A sample of 15 African American, American Indian or Alaskan Native, Latino, and Asian research leaders as key informants participated in the inquiry. Research team members and external project advisory panel members collaboratively developed the interview protocol consisting of 8 questions designed to elicit information about career development factors. Trained interviewers conducted semistructured telephone interviews to collect data. Verbatim transcripts of the audiotapes and participant demographics were the primary data that were analyzed using NVivo (Version 10.0). Results: Individual sociocultural challenges (e.g., cultural barriers, language/communication issues, family life issues, and limited collaboration opportunities), institutional research environmental concerns (e.g., bureaucracy, alienation, insufficient research support funds, and discrimination), and federal research agency policy and systems context–induced issues (e.g., limited mentorship opportunities, inadequate supply of minority research leaders and role models, unhealthy competition, and lack of equal opportunity) emerged among key informants’ perspectives as important barriers. Identified success strategies included the need for early career investigators to build, expand, and use support networks, establish multidisciplinary collaborations, develop strong work ethic, enhance research skills (e.g., methodological and grant writing), and obtain capable mentorship. Conclusions: The aforementioned factors should be considered in the creation of new career development models and paradigms aimed at diversifying the scientific workforce.

Published: September 2017

Purpose: In the previous analysis of key informant perspectives on minority research leaders’ career development factors, we identified individual and sociocultural, institutional, and federal research agency (i.e., National Institute on Disability, Independent Living, and Rehabilitation Research; National Institutes of Health; Agency for Healthcare Quality and Research; Office of Disability, Aging, and Long-Term Care Policy) policy and systems-induced challenges. An analysis of their viewpoints about what policy and systems-induced facilitators can be considered as actionable for increasing the pool of seasoned minority researchers was not undertaken. Here in this companion study, data collected on 15 key informants’ perspectives regarding policy initiatives and strategies that can be considered by these agencies to diversify the behavioral, social science, clinical, and biomedical scientific workforce were analyzed. Methods: This companion analysis employed the same methods as reflected in the previous study. Results: Select federal research agency policy and systems-induced factors (i.e., research career pathways, social justice context, designated funding streams, and interprofessional multidisciplinary collaborations) emerged as important. Conclusions: The findings can inform the development of new or modified federal research agency sponsored field initiated strategies and internal policy and systems that could lead to an increased supply of seasoned minority investigators.

Authors: Ulfa Maria , Fawzia Farhah Nayla
Published: September 2017

Adsorption models in a simple and accurate way to describe the geometry of the pores have been studied and validated experimentally to predict the adsorption capacity dibenzotiofen molecules on mesoporous carbon. The model is designed according to the size of the pore channels of mesoporous carbon and molecular arrangement dibenzotiofen that goes into the pores. To test the accuracy of the model is done by comparation with results of analysis of nitrogen adsorption-desorption to calculate the volume filled. The results showed that the results of the experimental adsorption data are within the range of values of the pore volume of mesoporous carbon. These results indicate that the pore geometry model molecule can accurately predict the adsorption capacity of a molecule in a mesoporous material.

Authors: Carmichael Jannet M. , Meier Joy , Robinson Amy , Taylor Janice , Higgins Diana T. , Patel Shardool
Published: September 2017

Purpose

The process and operational elements to establish a population health program using electronic medical record data in a Veterans Health Administration region are described.

Pharmacists are uniquely qualified to assume important roles in population health through the use of their clinical knowledge, assisted by electronic tools that consolidate and report patient-specific data for clinical care. Veterans Integrated Services Network (VISN) 21 has developed 300 dashboards and reports to improve the quality, safety, and value of healthcare to veterans. Within a group of specialty task forces, physicians, nurses, and pharmacists assist in the design and development of evidence-based tools to leverage timely electronic health information into metrics, benchmarks, and targets to assist with goal achievement. Examples of programs designed to improve care in 3 areas were selected for further description and review of outcomes. Population health improvement using Healthcare Effectiveness Data and Information Set and hepatitis C metrics were used to describe populations that may have an indication for evidence-based care but are not receiving it. Deprescribing efforts are described, as are medication safety monitoring efforts to prevent potential adverse events known to be associated with therapy.

Conclusion

Quality, safety, and value outcomes are the measures of success for population health programs in VISN 21. Data-rich project dashboards and reports are developed by pharmacist data analysts and implemented and used by teams of clinicians who provide continuous feedback and support to improve population health. The use of task forces, metrics, benchmarks, targets, and teams is instrumental in the successful application of these tools.
Local and international dimensions of credit provision by commercial banks in Kenya
Authors: Misati Roseline , Kamau Anne
Published: September 2017

Although considerable research has focused on the determinants of credit to the private sector, the issue still remains controversial, particularly with respect to the role of foreign banks in emerging markets. This study sought to understand the factors that affect lending of commercial bank loans both in form of foreign and local loans. It used panel data methods on quarterly bank-specific data covering the period from 2000 to 2013. In general, the results reveal that the ownership structure, housing variable and the size of the bank are the main determinants of aggregate commercial bank lending. This conclusion is maintained even when the determinants of foreign loans and local loans are specifically examined separately. However, the role of the liquidity measure is in not consistent in the different specifications while the role of interest rates is largely in line with expectation in most of the specifications. Implicitly, the results seem to suggest a need for mergers of small banks, policy focus on incentives for more local bank ownership and continued efforts on minimization of interest rate spread, which not only promote mortgage financing and home ownership, but also overall credit growth.

Authors: Büyükkamacı Nurdan , Karaca Gökçe
Published: September 2017

A life cycle assessment (LCA) approach was used in the assessment of environmental impacts of some polishing units for reuse of wastewater treatment plant effluents in agricultural irrigation. These alternative polishing units were assessed: (1) microfiltration and ultraviolet (UV) disinfection, (2) cartridge filter and ultrafiltration (UF), and (3) just UV disinfection. Two different energy sources, electric grid mix and natural gas, were considered to assess the environmental impacts of them. Afterwards, the effluent of each case was evaluated against the criteria required for irrigation of sensitive crops corresponding to Turkey regulations. Evaluation of environmental impacts was carried out with GaBi 6.1 LCA software. The overall conclusion of this study is that higher electricity consumption causes higher environmental effects. The results of the study revealed that cartridge filter and UF in combination with electric grid mix has the largest impact on the environment for almost all impact categories. In general, the most environmentally friendly solution is UV disinfection. The study revealed environmental impacts for three alternatives drawing attention to the importance of the choice of the most appropriate polishing processes and energy sources for reuse applications.

Published: September 2017

Cuantificar la biomasa forestal aérea del bosque es importante para evaluar la productividad y el efecto de sistemas silvícolas aplicados. El objetivo fue generar modelos alométricos para estimar biomasa aérea de Pinus oaxacana y mezcla de especies asociadas en respuesta a tratamientos silvícolas. En Ixtlán, Oaxaca, México, durante 2014 se establecieron 12 unidades experimentales de 400 m2 en rodales sometidos a diferente tratamiento silvícola: 1) sin tratamiento (conservación), 2) árboles padres, con regeneración de 10 años de edad, 3) árboles padres con regeneración de 15 años de edad, 4) matarrasa, con regeneración de siete años de edad. Con datos obtenidos mediante muestreo destructivo (n = 69 individuos) se construyeron modelos alométricos de biomasa de los compartimentos parciales y totales de P. oaxacana, arbustivo, en el piso forestal y sotobosque. En experimento mediante diseño completamente aleatorizado, los datos se sometieron a análisis de varianza, prueba de separación de medias (Duncan, 0.05), análisis clúster y modelos de regresión. Los modelos que utilizan variables de fácil medición, estiman entre 88% y 98% de la biomasa aérea de individuos de porte arbóreo y arbustivo de P. oaxacana y especies arbustivas asociadas. Los tratamientos silvícolas aplicados afectaron (p ≤ 0.05) la biomasa aérea acumulada en los compartimentos específicos y totales de P. oaxacana, así como la biomasa contenida en el piso forestal, sotobosque y total aéreo. Sin embargo, los rodales manejados bajo tratamientos de árboles padres (101.3 t ha-1) igualan la productividad de biomasa total aérea que el bosque bajo conservación (125.74 t ha-1).
