Published: February 2020

The current study deals with the development of scientific strategies for growing bioenergy crops in Ukraine that will assist the increasing of biomass in energy balance of Ukraine. Experimental research studies on determining the growth characteristics and development of energy willow on soddy ash gray soil according to the farming cultivation was carried out on the research fields of the Carpathian State Agricultural experimental station of the Institute of Agriculture in the Carpathian region of the NAAN and in laboratory conditions. The features of growth and development of energy willow varieties according to the growing conditions of the Western region for biofuels production was studied on the basis of quadruplex repetition. It was found that energy willow in the conditions of the Western region in terms of mineral fertilization with N40P300K300 and with the help of increasing the planting step to 60 cm influences the intensive noduling of vegetative mass. In this version the biggest height shoots (180 cm) is fixed. The increasing of seeding step from 40 cm to 60 cm in energy willow planting allows to get additionally 4,2 t/ ha of green mass and 1,9 t/ ha of dry mass. Mineral fertilization provides the increase of the productivity of 2,1 - 2,5 t/ ha of green mass and 0,5 - 1,0 t/ha of dry mass. On the basis of analyses of weeds change we can conclude that application of mechanical processing allowed to control the wild grass at possible level. However, some time after the treatments, shoots of annual and perennial weeds appeared. But the interrow tillage and bringing the herbicides provided practically full keeping down the weeds in the first half of willow vegetation

Published: February 2020

Leguminous crops grown in the radioactive contamination zone have the potential to accumulate radionuclides 137Cs and 90Sr to a large extent, thus contributing to radioactive contamination of livestock products, milk and meat. One of the effective methods in reducing the accumulation of radionuclides in crop production, in particular fodder, is the application of trace elements that are lacking in the Polissya area of Zhytomyr region. In addition, the trace elements contribute to increasing the yield of plants and improve their nutrition. As a result of the research in the Naroditsky district of Zhytomyr region, Polissya STOV, we found that the application of trace elements in the form of salts of trace elements Co, Cu, Zn, Mn contributed to the increase in the yield of green mass of white lupine and lupine of yellow on 2,4 and 3,6%, or on 10 and 10.7 g, of complexones of these trace elements, respectively, on 11,2 and 13,5%, or on 31,0 and 58,0 ts. Salts of trace elements contributed to a decrease in the specific activity of the green mass of lupine white by 18%, or 1.2 times, yellow lupine - by 11%, 1.2 times. Plasma complexes contributed to a decrease in the specific activity of green mass of white lupine and lupine of yellow on 24%, or in 1,3 times. Specific activity of the green mass of white lupine was high and exceeded the activity of the green mass of lupine yellow in 6.3 times, although the cultivation of cultures was carried out on the same fields, however, at different periods. White lupine was sown in the early spring, during which a considerable amount of precipitation fell during the vegetation period. Therefore, in our opinion, a significant increase in the specific activity of the green mass of white lupine was conditioned by the weather conditions. The maximum specific activity of the green mass of white lupine was 2003 Bq / kg, the minimum is 1526 Bq / kg, which is lower by 477 Bq. Reducing the specific activity of lupine is due to radio-blocking effect of micronutrient complexonates. Salts of trace elements contributed to a 1.2-fold decrease in the specific activity of the green mass of the culture.

Enzymatic Activity of Chernozem Typical Depending on The Main Cultivation of Soil and Fertilizer
Authors: Tsentylo L. V.
Published: February 2020

All agrotechnical and agrochemical measures aimed at increasing soil fertility have an effect on enzyme activity. Measures such as soil cultivation, the introduction of organic and mineral fertilizers into the soil,activate or suppress the enzymatic processes. The research relies on the intensity and direction of biochemical processes in the soil, containing a series of methods, the use of which has enabled the establishment of a favorable enzymatic active layer of arable chernozem typical. Such methods include: field, laboratory, analysis. The level of differentiation of protease, urease, phosphatase, amylase, catalase, depending on the cultivation of soil and fertilizer, was revealed in the process of comparative analysis of enzymic activity of typical black soil in sunflower agrocenosis. Field experiments on the study of fermentative activity of typical black currant were conducted during 2012-2016. The object of research was soil cover. It was established that the activation of biochemical processes in the soil is ensured by the organo-mineral fertilizer system - compost 4.5 t + N40P48K54 + 3.5 t by-products and seed weight per hectare of crop rotational area. Application of the mineral fertilizer system reduces the enzymatic activity of typical black soil. The highest activity of the protease and catalase passes in the arable layer for powered-unpowered cultivation. Higher phosphatase activity was observed for differentiated soil cultivation. Research on this problem should be continued in order to establish a relationship between the parameters of enzymatic activity of soil with the structure of microbial cenosis of typical black soil of different systems of basic cultivation and fertilization

Caracterización petrográfica de las pastas cerámicas de Antofagasta de la Sierra, un enfoque comparativo a nivel intersitios (Puna Austral Argentina).
Authors: Pérez Martina , Gasparotti Leticia
Published: February 2020

El objetivo de este trabajo es caracterizar las pastas cerámicas de diferentes sectores de Antofagasta de la Sierra a través de la petrografía, y aportar información que permita entender el manejo de las materias primas para comprender el tipo de relaciones que se establecieron entre los distintos grupos humanos. En esta ocasión se aborda la problemática que involucra a las interacciones y vínculos que se pudieron establecer entre las personas que habitaron el fondo de cuenca y los sectores intermedios de las quebradas en Antofagasta de la Sierra (provincia de Catamarca, Argentina) durante el período Tardío. Analizar la naturaleza de las inclusiones en las pastas, a través de la petrografía, permitió relacionar la manufactura cerámica con la geología regional, aunque se han identificado algunos conjuntos que podrían ser alóctonos. A nivel general, las muestras presentaron importante variabilidad petrográfica, lo cual refleja el empleo de distintas materias primas y posiblemente distintas tradiciones de manufactura. Las pastas de los fragmentos provenientes de los sitios ubicados en el fondo de cuenca, mostraron una mayor homogeneidad, lo cual podría deberse a necesidades funcionales demandadas por el proceso de intensificación agrícola. Por otro lado, en los sectores intermedios las pastas permiten inferir tradiciones locales a nivel intra-sitio. Con esta línea de investigación pretendemos aportar al conocimiento general de los sitios tardíos de la región, sumando el análisis petrográfico de las pastas cerámicas, vía que recientemente está comenzando a ser utilizada.

Poly(1-vinylimidazole) polyplexes as novel therapeutic gene carriers for lung cancer therapy
Authors: Kandasamy Gayathri , Danilovtseva Elena N , Annenkov Vadim V , Krishnan Uma Maheswari
Published: February 2020

The present work explores the ability of poly(1-vinylimidazole) (PVI) to complex small interfering RNA (siRNA) silencing vascular endothelial growth factor (VEGF) and the in vitro efficiency of the formed complexes in A549 lung cancer cells. The polyplex formed was found to exhibit 66% complexation efficiency. The complexation was confirmed by gel retardation assays, FTIR and thermal analysis. The blank PVI polymer was not toxic to cells. The polyplex was found to exhibit excellent internalization and escaped the endosome effectively. The polyplex was more effective than free siRNA in silencing VEGF in lung cancer cells. The silencing of VEGF was quantified using Western blot and was also reflected in the depletion of HIF-1α levels in the cells treated with the polyplex. VEGF silencing by the polyplex was found to augment the cytotoxic effects of the chemotherapeutic agent 5-fluorouracil. Microarray analysis of the mRNA isolated from cells treated with free siRNA and the polyplex reveal that the VEGF silencing by the polyplex also altered the expression levels of several other genes that have been connected to the proliferation and invasion of lung cancer cells. These results indicate that the PVI complexes can be an effective agent to counter lung cancer.

Published: February 2020

The increase in the number of Unmanned Aerial Vehicles (UAVs) and Micro Air Vehicles (MAVs), which are used in a variety of applications has led to a surge in low Reynolds number aerodynamics research. Flow around fixedwing MAVs has an unusual behavior due to its low aspect ratio and operates at low Reynolds number, which demanded to upgrade the used wind tunnel for this study. This upgrade enables measuring the small aerodynamics forces and moment of fixed-wing MAVs. The wind tunnel used in this work is upgraded with a state of art data acquisition system to deal with the different sensors signals in the wind tunnel. For accurate measurements, the sting balance, angle sensor, and airspeed sensor are calibrated. For validation purposes, an experiment is made on a low aspect ratio flat plate wing at low Reynolds number, and the measured data are corrected and compared with published results. The procedure presented in this paper for the first time gave a detailed and complete guide for upgrading and calibrating old wind tunnel, all the required corrections to correct the measured data was presented, the turbulence level correction new technique presented in this paper could be used to estimate the flow turbulence effect on the measured data and correct the measured data against published data.
INDONESIAN PEER TO PEER LENDING (P2P) AT ENTRANT’S DISRUPTIVE TRAJECTORY
Authors: Kohardinata Cliff , Soewarno Noorlailie , Tjahjadi Bambang
Published: February 2020

Peer to peer (P2P) lending in Indonesia has been growing rapidly, therefore there is the potential for disruptive innovation processes in the financial sector. The aim of this study is to examine the impact of the growth of P2P lending on the growth of bank lending for micro, small and medium enterprises (MSME) and Non-MSME debtors. Separating the scale of the debtor is important, given the initial process of disruptive innovation of reaching areas that are not the incumbent’s main target. The examination was conducted in this study using panel data regression, whereby the examination was done in stages. This was an overall examination without differentiating between the regions, further examination conducted with more detail by separating between the loans inside and outside Java Island. This is because the economic structure in Indonesia is still dominated by the regions in Java, but FinTech is generally able to grow in areas with less developed local economies. The result of this study is consistent overall, Java and outside Java Island, as shows that the growth in P2P lending in Indonesia does not have a significant impact on the growth of bank loans for Non-MSME lending. However, it does have a negative impact on the growth of bank loans for MSME lending. This is in line with the entrant’s disruptive trajectory process by which the entrants enter the competition through an underserved market (niche markets) and not through the main target market of the incumbent (MSME).
Penumbral Brightening Events Observed in AR NOAA 12546
Authors: Murabito Mariarita , Guglielmino Salvo L. , Ermolli Ilaria , Stangalini Marco , Giorgi Fabrizio
Published: February 2020

Penumbral transient brightening events have been attributed to magnetic reconnection episodes occurring in the low corona. We investigated the trigger mechanism of these events in active region NOAA 12546 by using multiwavelength observations obtained with the Interferometric Bidimensional Spectrometer, by the Solar Dynamics Observatory, the Interface Region Imaging Spectrograph, and the Hinode satellites. We focused on the evolution of an area of the penumbra adjacent to two small-scale emerging flux regions (EFRs), which manifested three brightening events detected from the chromosphere to the corona. Two of these events correspond to B-class flares. The same region showed short-lived moving magnetic features (MMFs) that streamed out from the penumbra. In the photosphere, the EFRs led to small-scale penumbral changes associated with a counter-Evershed flow and to a reconfiguration of the magnetic fields in the moat. The brightening events had one of the footpoints embedded in the penumbra and seemed to result from the distinctive interplay between the preexisting penumbral fields, MMFs, and the EFRs. The IRIS spectra measured therein reveal enhanced temperature and asymmetries in spectral lines, suggestive of event triggering at different heights in the atmosphere. Specifically, the blue asymmetry noted in C ii and Mg ii h&k lines suggests the occurrence of chromospheric evaporation at the footpoint located in the penumbra as a consequence of the magnetic reconnection process at higher atmospheric heights.
Deflating Super-puffs: Impact of Photochemical Hazes on the Observed Mass–Radius Relationship of Low-mass Planets
Authors: Gao Peter , Zhang Xi
Published: February 2020

The observed mass–radius relationship of low-mass planets informs our understanding of their composition and evolution. Recent discoveries of low-mass, large-radius objects (“super-puffs”) have challenged theories of planet formation and atmospheric loss, as their high inferred gas masses make them vulnerable to runaway accretion and hydrodynamic escape. Here we propose that high-altitude photochemical hazes could enhance the observed radii of low-mass planets and explain the nature of super-puffs. We construct model atmospheres in radiative-convective equilibrium and compute rates of atmospheric escape and haze distributions, taking into account haze coagulation, sedimentation, diffusion, and advection by an outflow wind. We develop mass–radius diagrams that include atmospheric lifetimes and haze opacity, which is enhanced by the outflow, such that young (∼0.1–1 Gyr), warm (T
eq ≥ 500 K), low-mass objects (M

c
 < 4 M
⊕) should experience the most apparent radius enhancement due to hazes, reaching factors of three. This reconciles the densities and ages of the most extreme super-puffs. For Kepler-51b, the inclusion of hazes reduces its inferred gas mass fraction to <10%, similar to that of planets on the large-radius side of the sub-Neptune radius gap. This suggests that Kepler-51b may be evolving toward that population and that some warm sub-Neptunes may have evolved from super-puffs. Hazes also render transmission spectra of super-puffs and sub-Neptunes featureless, consistent with recent measurements. Our hypothesis can be tested by future observations of super-puffs’ transmission spectra at mid-infrared wavelengths, where we predict that the planet radius will be half of that observed in the near-infrared.

Authors: Jomon G. , Jojish J. V. , Santhanakrishnan T.
Published: February 2020

Protecting war ships from torpedo attack is considered as the most challenging task in Anti-Submarine Warfare. Torpedo Defence System (TDS) is an essential fitment on modern high value platforms. Timely detection and identification of a torpedo attack is the primary function of a TDS. Localisation and countermeasures against the weapon are the next stage in torpedo defence. Detection of modern torpedoes with long endurance can only be achieved using an underwater sensor suit with wide frequency coverage. Tactical use of multiple counter measures is essential for evading an attacking torpedo with intelligent homing mechanism. Individual sensors and counter measures are no longer considered as a solution; they are rather considered as components of a large network of systems to protect the platform from torpedo attack. A System of Systems (SOS) architecture with multiple sensors, processing techniques, countermeasures and tactics are presented in this paper for achieving fail-safe torpedo defence capability.

Published: February 2020

A indústria de alimentos investe cada vez mais no segmento de bebidas fermentadas de forma a se obter produtos com alegação funcional e de elevada aceitação por parte do consumidor. O objetivo deste estudo foi avaliar a influência da adição de grãos de kefir de leite sobre as características microbiológicas e físico-químicas de uma bebida probiótica sabor chocolate. Foram realizadas as análises físico-químicas para determinação do pH, acidez, lactose, sacarose, umidade, resíduo mineral fixo, proteínas, lipídios, carboidrato e energia, além de análises microbiológicas (contagem de bactérias ácido-láticas - BAL), bolores e leveduras- BL, presença de coliformes totais e termotolerantes nas bebidas fermentadas não saborizadas e saborizadas com chocolate em pó e açúcar. As bebidas probióticas não saborizadas com adição de 5% e 10% de kefir (BAL - 5,1x109 e 2,1x109 UFC/mL, respectivamente) e as bebidas probióticas saborizadas com adição de 5% de kefir (BAL - 1,3x 109 UFC/mL) apresentaram conteúdo de BAL semelhantes. O conteúdo de BL foi 100 vezes maior bebida probiótica não saborizado a 5% comparado ao 10% (4,1x107 e 3,3x105 UFC/mL, respectivamente) e 1000 vezes maior no kefir saborizado 10% comparado ao 5% (1,2x106 e 4,5x103 UFC/mL, respectivamente). Todas as amostras apresentaram ausência de coliformes totais e termotolerantes. Em relação às análises físico-químicas, observou-se que as bebidas probióticas não saborizadas e saborizadas, com maior concentração dos grãos de kefir (10%) apresentaram menor pH (4,2 e 4,8, respectivamente) e maior acidez (0,74% e 0,81%, respectivamente), além de, menor teor de lactose (3,5% e 2,7%, respectivamente) e lipídeo (2,8% e 3,4%, respectivamente) comparada à bebida com 5% de grãos de kefir. O desenvolvimento de bebidas probióticas com sabor chocolate pode agregar valor comercial, sensorial, e nutricional e ser uma alternativa viável de alimento funcional. Mais estudos são necessários para se avaliar as características sensoriais e aceitabilidade destas bebidas probióticas.

Biossurfactantes são substâncias tensoativas com inúmeras aplicações. A produção de biossurfactantes a partir de 5, 10 e 15% de soro de queijo foi realizada por Bacillus subtilis e Corynebacterium aquaticum na concentração de 2% e meio mineral mínimo. O cultivo foi realizado a 200 rpm, 30ºC por 48 h. Para os resíduos de corvina (Micropogonias furnieri) foram realizados 2 planejamentos experimentais fatoriais 32, onde foram avaliadas a influência dos micro-organismos (2%) e a concentração de pescado 0,83, 1,66 e 2,50%. Um dos planejamentos foi realizado em biorreatores com chicanas e sem chicanas. As condições de cultivo foram, agitação de 200 rpm, 30ºC por 72 h. Os cultivos que utilizaram o soro de queijo como substrato obtiveram baixa redução da tensão superficial. Nos cultivos com resíduos de pescado houve redução da tensão superficial para valores próximos de 24 mN.m-1 nos biorreatores com chicanas e 27 mN.m-1 para os sem chicanas. O melhor resultado foi obtido nos biorreatotes com chicanas onde foi utilizada a concentração de 0,83% de pescado e o micro-organismo Corynebacterium aquaticum, obtendo 23,74 mN.m-1 de tensão superficial, sendo o valor obtido menor do que valor do biossurfactante mais referenciado na literatura, a Surfactina, que possui tensão de 27 mN.m-1.
Concentração de NaOH na cor de mirtilo (Vaccinium ashei) congelado e in natura como pré-tratamento à desidratação osmótica

Published: February 2020

O mirtilo, além de possuir alto valor agregado, possui também uma camada cerosa que envolve o fruto e o protege de agentes externos. No entanto, para a desidratação osmótica, essa cera é indesejável, já que evita troca de solutos e solventes com o meio. Comumente utilizado, o NaOH possui propriedades saponificantes, podendo então remover a cera superficial desse tipo de fruta. Todavia, seu uso pode resultar em alterações nas antocianinas, principalmente em frutas previamente congeladas, devido à lesão celular. Portanto, o objetivo deste trabalho consistiu em avaliar a cor de frutas de mirtilo congeladas e in natura imersas em NaOH como pré-tratamento à desidratação osmótica. As frutas de mirtilo (Vaccinium ashei) cv. Alice Blue foram coletadas do germoplasma da Embrapa Clima Temperado, higienizadas e congeladas a -4ºC. Posteriormente, as frutas foram imersas em NaOH em diferentes concentrações (0, 0,1, 0,5, 1,0, 1,5 e 2,0%.) por 1 minuto sob leve agitação. Foi avaliada a cor em aparelho Minolta modelo CR-310 com resposta nos parâmetros “L”, “a” e “b”. Os resultados demonstram que o parâmetro “L” foi influenciado tanto pelo congelamento quanto pela presença do NaOH. Concentrações superiores a 1% aumentam a luminosidade dos produtos avaliados, indicando reação NaOH com antocianinas. O parâmetro “a” foi influenciado apenas pelo congelamento, ao passo que o parâmetro “b” não sofreu nenhuma modificação. Os resultados indicam que o uso do congelamento não é indicado em casos em que as próximas etapas do processamento do mirtilo esteja associado ao uso do NaOH.

As intoxicações alimentares ocorrem devido a multiplicação de microrganismos patogênicos em diferentes tipos de alimentos, sendo o queijo um dos principais relacionados com essa enfermidade. A indústria adota as Boas Práticas de Fabricação (BPF), que consistem em um sistema de controle de qualidade, que visa garantir a segurança alimentar. Quando a produção do queijo ocorre de forma artesanal, nem sempre são observadas as BPF e os controles higiênico-sanitários recomendados, colocando em risco a saúde do consumidor. O objetivo deste estudo foi verificar a presença de Escherichia coli e bactérias do gênero Staphylococcus em queijos tipo Minas Frescal, comercializados em feiras livres e supermercados do Oeste do Paraná. Foram analisadas quinze amostras de queijos, sendo seis amostras formais/industrializadas, e nove oriundas de produtores informais/artesanais. Foi possível observar que 86,66% das amostras se apresentaram acima do valor estabelecido para coliformes termotolerantes, e 73,33% do total das amostras se mostraram contaminadas com E. coli (sete amostras de produtores informais e quatro das amostras de produtores formais). Duas amostras formais e cinco amostras informais se apresentaram acima dos limites de contaminação por Staphylococcus estabelecidos pela RDC n° 12 da ANVISA, classificadas como impróprios para o consumo humano. Estes resultados evidenciam possíveis falhas no controle de qualidade, falta de condições higiênico-sanitárias durante as etapas de produção, e/ou após o processamento, por meio do manuseio inadequado, tratamento térmico ineficiente, refrigeração insuficiente, ou uso de leite de má qualidade.

A maceração pré-fermentativa a frio impede o início da fermentação, determinando um tempo de maceração em fase aquosa. Este trabalho teve como objetivos avaliar o efeito da associação da suplementação de taninos à maceração a frio e ao armazenamento de cachos a frio, nas propriedades químicas de vinhos da variedade Merlot da Região da Campanha Gaúcha. Para a vinificação usou-se uva da variedade Merlot e durante a maceração foram realizadas três remontagens diárias e a fermentação alcoólica aconteceu com temperaturas de 20 a 25°C Os tratamentos foram avaliados após a descuba, após o término da fermentação malolática e após o engarrafamento. Quando utilizados manejos de maceração pré-fermentativa a frio e armazenamento da uva a frio, foi observada redução da acidez volátil e aumento do teor alcoólico, mas não exerceram influências nos resultados analíticos de índice de cor, índice de polifenóis totais, antocianinas totais e fenóis totais no momento do engarrafamento. Os resultados indicam que é tecnicamente possível a produção de vinho tinto Merlot jovem utilizando manejos de maceração pré-fermentativa a frio e armazenamento da uva a frio.
European Science Editing is in full open access now
Authors: Bazdaric Ksenija
Published: February 2020

I am excited to announce that with this volume European Science Editing (ESE) has shifted from the print to a fully digital open access version. The journal underwent several changes last year. First of all, our publisher, the European Association of Science Editors (EASE) was generously offered – and accepted – a new ARPHA submission system (powered by PenSoft). Together with the EASE president Pippa Smart and EASE Council, we decided to transform ESE into a fully open access online journal. After several months of planning and re-thinking our strategy, a small working group (some members of the EASE Council and of ESE’s associate editors) prepared a proposal, the main idea of which was to divide the journal in two overlapping publications: European Science Editing and EASE Digest. The former will continue to publish original articles, reviews (formerly “essays”), viewpoints, and correspondence using the fully open access ARPHA submission system (flow publishing) but will drop the other sections, namely News notes, The editor’s bookshelf, This site I like, and EASE Forum Digest). These sections, which our readers consider particularly valuable, will now be published in EASE Digest with a few selected articles from ESE. The Digest will be available to EASE members only. As the proposal was accepted by the EASE Council in September 2019, the journal’s transformation is already under way. I wish to thank Silvia Maina (This site I like), Fiona Murphy (Book reviews), Elise Langdon-Neuner (EASE-Forum Digest), Anna Maria Rossi (The Editor’s bookshelf), and James Hartley and Denys Wheatley (members of the International Advisory Board) for the great work they have done and for their cooperation.
Mapping domain characteristics influencing Analytics initiatives: The example of Supply Chain Analytics
Authors: Herden Tino
Published: February 2020

Purpose: Analytics research is increasingly divided by the domains Analytics is applied to. Literature offers little understanding whether aspects such as success factors, barriers and management of Analytics must be investigated domain-specific, while the execution of Analytics initiatives is similar across domains and similar issues occur. This article investigates characteristics of the execution of Analytics initiatives that are distinct in domains and can guide future research collaboration and focus. The research was conducted on the example of Logistics and Supply Chain Management and the respective domain-specific Analytics subfield of Supply Chain Analytics. The field of Logistics and Supply Chain Management has been recognized as early adopter of Analytics but has retracted to a midfield position comparing different domains.Design/methodology/approach: This research uses Grounded Theory based on 12 semi-structured Interviews creating a map of domain characteristics based of the paradigm scheme of Strauss and Corbin.Findings: A total of 34 characteristics of Analytics initiatives that distinguish domains in the execution of initiatives were identified, which are mapped and explained. As a blueprint for further research, the domain-specifics of Logistics and Supply Chain Management are presented and discussed.Originality/value: The results of this research stimulates cross domain research on Analytics issues and prompt research on the identified characteristics with broader understanding of the impact on Analytics initiatives. The also describe the status-quo of Analytics. Further, results help managers control the environment of initiatives and design more successful initiatives.
Relocation to a Long-Term Care Facility: Working With Patients and Families Before, During, and After
Authors: Kao Hsueh-Fen S. , Travis Shirley S. , Acton Gayle J.
Published: February 2020

Permanent relocation of a dependent older adult to a long-term care facility can occur for a number of reasons, including the need for postacute care or a higher level of care than can be provided in a less-restrictive environment, and/or the inability of family members or others to care for the individual in a noninstitutional setting. Outcomes of institutional placement may be either negative, such as the older adult experiencing relocation stress syndrome, or positive, such as improved management of chronic illnesses and reversal of functional decline. This article offers a review of the factors that predict when and where older adults will relocate for institutional long-term care, an overview of individual transitions to institutional care, and suggestions for seamless transitions during the preinstitutionalization, transitional, and postinstitutionalization phases of relocation, which are guided by a transactionist approach to stress and coping.
Rational Emotive Behavior Therapy: Disputing Irrational Philosophies
Authors: Sacks Susan Bendersky
Published: February 2020

This article provides an overview of the concepts and techniques of rational emotive behavior therapy to distinguish it from cognitive-behavioral therapy. Rational emotive behavior therapy proposes that psychological disturbance is largely created and maintained through irrational philosophies consisting of internal absolutistic demands. This therapy strives to produce sustained and profound cognitive, emotive, and behavioral change through active, vigorous disputation of underlying irrational philosophies.
Understanding Those Who Self-Mutilate
Authors: Starr Dianne Lindley
Published: February 2020

Self-mutilating behavior is a symptom seen in both men and women with various psychiatric disorders, but the majority of those who self-mutilate are women with borderline personality disorder. This complex, maladaptive behavior is used by clients as a means of self-preservation and emotion regulation, and is often associated with childhood trauma. Clients who self-mutilate perceive they receive poor care in hospital emergency departments and are retraumatized by these experiences. Clinicians who understand the complexity and purposes of self-mutilating behavior are better able to provide clients with supportive, empathetic care.

Authors: Yilmazer Yagmur Çolak , Buldukoglu Kadriye , Tuna Tugçe , Güney Sevin Seda
Published: February 2020

The current semi-experimental pilot study was conducted to investigate the effects of dance and movement therapy methods (DMTM) on compassion satisfaction, burnout, and compassion fatigue in nurses using a pre-/posttest design. Nurses (
N
= 8) with low compassion satisfaction, high burnout, and high compassion fatigue participated in eight sessions of DMTM. Upon completion of the program, average compassion satisfaction levels increased, and burnout and compassion fatigue levels decreased. Although further testing with larger samples is necessary, preliminary results indicate DMTM is effective for addressing compassion satisfaction, burnout, and compassion fatigue in nurses. [

Published: February 2020

The objective of the current study was to describe the perspectives of people who use illicit drugs regarding the availability and effectiveness of drug treatment services. A total of 111 participants with illicit drug use experience were recruited from an inner city community in São Paulo, Brazil. Treatment services were considered to be essential and necessary by the majority of participants, whereas general hospitals and mental health services were considered to be the most highly available treatment options for illicit drug use. Participants also indicated that treatment led to positive changes in their lives, highlighting the importance of drug treatment services for promoting the rights and responsibilities of people who use illicit drugs. Results support the need for services that value and respect the fundamental rights of people who use illicit drugs. [

L’intercompréhension, un tremplin pour les conversations exolingues en e-tandem ?
Authors: Marneffe Monique
Published: February 2020

Les perceptions d’environ quatre-vingt-dix étudiants sont analysées en relation avec deux modes d’interaction dans des e-tandems synchrones (compétence orale) : les interactions en intercompréhension (mode bilingue: chacun parle sa propre langue 1 au sein d’une même conversation) et les interactions monolingues exolingues (une langue partagée par un locuteur L1 et un locuteur L2 est parlée en alternance, d’une semaine à l’autre). Les étudiants sont francophones (ULiège) et néerlandophones (KU Leuven) (premier cycle en linguistique appliquée). Deux groupes sont formés: le premier groupe échange dans sa langue 1 (intercompréhension) (quatre conversations) puis passe en mode monolingue exolingue (quatre conversations: deux en français et deux en néerlandais). Le deuxième groupe interagit directement en mode monolingue exolingue pendant huit conversations. Deux questionnaires sont remplis: l'un après les quatre premières conversations, l'autre après les quatre dernières. L'objectif de la recherche est de spécifier quel type d'échange est préféré et si les préférences varient d'une communauté culturelle à l'autre. Les premiers résultats semblent montrer que les francophones considèrent l’intercompréhension comme utile au début des conversations, tandis que les néerlandophones considèrent ce mode d'interaction plutôt superflu.
