Eucyclops delongi sp. nov. (Cyclopiformes: Copepoda: Crustacea) from the River Lena delta, Polar Eastern Siberia, Russia
Authors: Alekseev V.R. , Abramova E.N. , Chaban O.A.
Published: December 2019

A new species of Eucyclops (Cyclopiformes: Copepoda: Crustacea) is described from a bog-lake on the top of a hill near Titary fisherman village in the top of The River Lena delta, Eastern Siberia, Russia. Eucyclops delongi sp. nov. belongs to the speratus group of species and can be clearly separated from other related species by a combination of characters that include smooth hyaline membrane on 3 distal segments of antennule, missing of long hairs on antenna basipodite posterior surface (on the top), presence of several long setules on the distal side of the caudal rami (saw), homogeneous hair row on both sides of inner coxal spine in 4th swimming legs, relatively short caudal rami (length/width ratio less than five), clearly seen difference in caudal saw denticles on lateral edge, very long innermost caudal seta subequal to ramus length, inner spine of distal segment of endopodite 4th swimming leg 1.1 times as long as segment itself. Male of new species can also be separated from other species by a combination of the following characters: antenna basipodite on posterior surface without groups of long hairs (on the top), coxal spine of 4th swimming legs homogenously covered with long hairs, rudimental 5th legs with relatively short inner spine similar in length to segment itself, rudimental 6th legs with 3 appendages including strong inner spine reaching the middle of the next segment, outer seta as long as spine, middle seta is shorter than spine. This species is suggested to be an endemic of Arctic zone in Eastern Siberia (Beringia), which is well known as a Pleistocene refuge during glaciation in North-East Asia.

Liderazgo escolar: Una mirada a los criterios de éxito pedagógico de los Jefes de Unidad Técnica Pedagógica (UTP) en Chile.
Authors: Aravena Felipe , Cádiz Marilyn , Peña Cinthia , González Macarena , Nuñez Claudio
Published: December 2019

This study analyzes the importance of the leadership played by the Heads of Technical-Pedagogical Units (UTP, for its Spanish acronym), in terms of the criteria for a successful lesson. A qualitative research study was carried out, with the participation of 27 Heads of UTP from the provinces of San Felipe and Los Andes. From an emergent coding, it is concluded that these academic leaders consider that a successful lesson contains: a clearly identified structure, a learning goal, consideration of student diversity, motivation, and the monitoring process and feedback from teachers. The findings from this research contribute to a reflection on the design of specific professional development programs oriented to UTP.
Una década de investigación empírica sobre el liderazgo educativo en Chile. Una revisión sistemática de los artículos publicados en revistas indexadas (2008-2019)
Authors: Weinstein José , Muñoz Gonzalo , Sembler Matías , Marfán Javiera
Published: December 2019

In the last decade in Chile, the government and institutions have launched different policies designed to promote educational leadership. However, little is known about the characteristics of the research done on this topic. This topographical review has systematically analyzed the articles on educational leadership in Chile, which have an empirical research base, and which have been published in indexed journals between 2008 and 2019. The results reveal that 47 articles have been published, with an increasing number from the year 2016 onwards. These articles were published by a group of 85 authors, the majority of whom have only published one article. The studies are characterized as mostly descriptive and qualitative, with few that have done random samples or that exploited the existing secondary data. Approximately 40% of the articles declare they did not receive financial support develop their research. The most studied research focuses were school leaders, as well as municipal (public) elementary schools. The publications reviewed are concentrated in Scopus indexed and Latin American journals. The characterization made allows us to consider as emergent, research on the field of school leadership, and to suggest a set of measures that would allow its consolidation.

Authors: Ulubey Özgür , TİCAN BAŞARAN Semra
Published: December 2019

The aim of this study is to evaluate the initial teacher training programs updated in 2018 in Turkey. In the study, the basic interpretive research design was used. Participants of the study were 32 faculty members from different programs in a faculty of education of a university in the western part of Turkey. Data were collected via face to face interviews using semi-structured interview form. Findings of the study generally revealed that 2018 initial teacher training programs were not prepared in line with curriculum development principles. The faculty members think that the changes in the programs cannot meet the needs of qualified teacher training. They recommended updating the teacher training programs in line with the curriculum development principles, increasing the weekly course hours, adding the implementation hours in the courses and adding the school experience course back to the programs.

Published: December 2019

OBJECTIVE

Spinal schwannoma remains the third most common intradural spinal tumor following spinal meningioma and ependymoma. The available literature is generally limited to single-institution reports rather than epidemiological investigations. As of 1/1/2004, registration of all benign central nervous system tumors in the United States became mandatory after the Benign Brain Tumor Cancer Registries Amendment Act took action, which provided massive resources for United States population-based epidemiological studies. This article describes the epidemiology of spinal schwannoma in the United States from January 1, 2006, through December 31, 2014.

METHODS

In this study, the authors utilized the Central Brain Tumor Registry of the United States, which corresponds to 100% of the American population. The Centers for Disease Control and Prevention’s National Program of Cancer Registries and the National Cancer Institute’s Surveillance Epidemiology and End Results program provide the resource for this data registry. The authors included diagnosis years 2006 to 2014. They used the codes per the International Coding of Diseases for Oncology, 3rd Edition: histology code 9560/0 and site codes C72.0 (spinal cord), C70.1 (spinal meninges), and C72.1 (cauda equina). Rates are per 100,000 persons and are age-adjusted to the 2000 United States standard population. The age-adjusted incidence rates and 95% confidence intervals are calculated by age, sex, race, and ethnicity.

RESULTS

There were 6989 spinal schwannoma cases between the years 2006 and 2014. The yearly incidence eminently increased between 2010 and 2014. Total incidence rate was 0.24 (95% CI 0.23–0.24) per 100,000 persons. The peak adjusted incidence rate was seen in patients who ranged in age from 65 to 74 years. Spinal schwannomas were less common in females than they were in males (incidence rate ratio = 0.85; p < 0.001), and they were less common in blacks than they were in whites (IRR = 0.52; p < 0.001) and American Indians/Alaska Natives (IRR = 0.50; p < 0.001) compared to whites. There was no statistically significant difference in incidence rate between whites and Asian or Pacific Islanders (IRR = 0.92; p = 0.16).

CONCLUSIONS

The authors’ study results demonstrated a steady increase in the incidence of spinal schwannomas between 2010 and 2014. Male sex and the age range 65–74 years were associated with higher incidence rates of spinal schwannomas, whereas black and American Indian/Alaska Native races were associated with lower incidence rates. The present study represents the most thorough assessment of spinal schwannoma epidemiology in the American population.

Published: December 2019

OBJECTIVE

Compression of the spinal cord by thoracic ossification of the posterior longitudinal ligament (T-OPLL) often causes severe thoracic myelopathy. Although surgery is the most effective treatment for T-OPLL, problems associated with surgical intervention require resolution because surgical outcomes are not always favorable, and a small number of patients experience deterioration of their neurological status after surgery. The aim of the present study was to examine the surgery-related risk factors contributing to poor clinical outcomes for myelopathy caused by T-OPLL.

METHODS

Data were extracted from the records of 55 patients with thoracic myelopathy due to T-OPLL at institutions in the Fukuoka Spine Group. The mean follow-up period was 5.3 years. Surgical outcomes were assessed using the Japanese Orthopaedic Association (JOA) scale. To investigate the definitive factors associated with surgical outcomes, univariate and multivariate regression analyses were performed with several patient-related and surgery-related factors, including preoperative comorbidities, radiological findings, JOA score, surgical methods, surgical outcomes, and complications.

RESULTS

Neurological status improved in 33 patients (60.0%) and deteriorated in 10 patients (18.2%) after surgery. The use of instrumentation was significantly associated with an improved outcome. In the comparison of surgical approaches, posterior decompression and fusion resulted in a significantly higher neurological recovery rate than did anterior decompression via a posterior approach and fusion or decompression alone. It was also found that postoperative neurological status was significantly poorer when there were fewer instrumented spinal levels than decompression levels. CSF leakage was a predictable risk factor for deterioration following surgery.

CONCLUSIONS

It is important to identify preventable risk factors for poor surgical outcomes for T-OPLL. The findings of the present study suggest that intraoperative CSF leakage and a lower number of instrumented spinal fusion levels than decompression levels were exacerbating factors for the neurological improvement in T-OPLL surgery.
Intra and postoperative effectives of oral transmucosal administration of phenylbutazone for pain managament in dogs
Authors: KİBAR Murat
Published: December 2019

The aim of the
present study was to evaluate the efficacy and analgesic duration of single
dose of phenylbutazone administered by oral transmukosal route immediately
before induction of anesthesia in dogs undergoing elective ovariohysterectomy.
Eight-teen sexually intact female dogs (weiging between 5 and 30 kg, and 1 to 7
yrs of age) referred for ovariohysterectomy procedure from a local shelter at
regular intervals over 3 months were included in the study. The dogs were
administered phenylbutazone on the basis of their respective treatment group
(20 mg/kg via oral transmucosal administration) immediately before anesthetic
induction. The syringe was placed in the cheek pouch of the dog, and
phenylbutazone was slowly administered over a period of 1 to 3 minutes to
ensure the drug did not drip out of the dog’s mouth, or was not swallowed by
the dog. In control group, 0.9% NaCl was administered in the cheek pouch of the
dog. Throughout the study, pre and postoperative pain was assessed at baseline
(before induction of anesthesia) and then at 0.5, 1, 2, 3, 8, and 24 hrs after the
surgery. Group
oral transmucosal had significantly lower Glascow pain scores than the control
group at the 0.5, 1, 2, 3, and 8 hour postoperative periods. In conclusion, a
single dose of phenylbutazone administered via the oral transmucosal route
before surgery may be particularly beneficial for acheiving reasonable
perioperative analgesia, but not in postoperative period.

Типи міжпоколінної комунікації як механізму соціокультурної спадкоємності
Authors: Макарова Марія Володимирівна
Published: December 2019

Мета статті. Охарактеризувати сутність комунікації між різними поколіннями в процесі розвитку суспільства, обумовленої її специфікою та відмінностями від усіх інших видів соціальних комунікацій. Адже ні професійна, ні міжособистісна, ні педагогічна, ні масова комунікації не є такою ж мірою джерелом історичного розвитку. Методологія дослідження полягає у застосуванні загальнонаукових методів і підходів, зокрема діалектичного, що дає можливість розглянути соціальні та комунікативні процеси в їх органічній цілісності, проаналізувати сутність комунікації між різними поколіннями в конкретно-історичних соціальних системах. З’ясувати, як одночасно з розвитком суспільства відбувається видозміна міжпоколінної комунікації, а також виявити суперечності в просторі останньої. Актуальність дослідження продиктована тим, що між поколіннями формується простір нерозуміння, взаємного відторгнення, неприйняття, виникає «зона мовчання». Наукова новизна полягає у виявленні сутності комунікації у різних типах суспільств за типологією М. Мід та М. Петрова. Висновки. З’ясовано, що процеси міжпоколінної комунікації відбуваються в суспільстві, як правило, спонтанно, в залежності від його типу, структури влади, соціально-економічних відносин та ін. Виявлено, що незабезпечення міжпоколінної комунікації зв’язку між минулим, теперішнім і майбутнім стає умовою появи певних деструктивних елементів, оскільки орієнтація тільки на теперішнє та специфіка сучасної соціалізації вносять розрив у діалог поколінь. Доведено, що в умовах кризи суспільного розвитку міжпоколінний комунікативний простір починає формуватися в процесі соціалізації поколінь. Тому для напрацювання способів запобігання розриву спадковості в культурі постає необхідність в особливій увазі до дослідження конфліктів у міжпоколінній комунікації.

Authors: Armentia Vizuete José Ignacio , Marín Murillo Flora , Rodríguez González María del Mar , Marauri Castillo Iñigo
Published: December 2019

News on nutrition has become a regular feature on the media agenda. This paper analyses characteristics of texts on this topic published during 2017 in the digital editions of El País and La Vanguardia, the two newspapers with the widest circulation in Spain. The study looked in greater depth at aspects such as the main topics being addressed, authorship, genres and headlines of the texts, framing, sources and the number of comments from readers. The two chosen newspapers reveal considerable differences in matters such as quantity of sources used or the number of comments that are generated by this type of news. The conclusions from this study include the appearance of specific sections dedicated to nutrition and a shortfall in journalistic specialisation in this field.
Portrayal of the journalist in Spanish cinema from 1990 to 2010
Authors: San José de la Rosa Cristina , Miguel Borrás Mercedes , Gil Torres Alicia
Published: December 2019

The journalist is a regular character in Spanish films, and analysing this role is fundamental in learning more about the profession. The aim of this research is to identify the profile of the journalist in cinema from 1990 to 2010, two decades of drastic changes in the modes of communication in our country. In its empirical phase, one of the fundamental contributions can be found in the recovery of Morphology of the Folktale (1928), by Russian Folklorist-Scholar Vladimir Propp, which can be used to establish the characteristics of the reporter from a structuralist point of view. In this book, the conclusion reached is that the heroes are those in charge of serious journalism, whereas the villains, mainly women, are the stars of the television ‘boom’ with a predominance of morbidity and deceit on the small screen.
Screening of Nutraceuticals and Plant Extracts for Inhibition of Amyloid-β Fibrillation
Authors: Witter Steffi , Samoson Ago , Vilu Raivo , Witter Raiker
Published: December 2019

Fluorescence spectroscopy for in vitro amyloid-β (Aβ) fibrillation diagnosis and spectral fluorescence signature for the identification of bioactive compounds were applied to study traditional Ayurvedic nutraceuticals – Brahmi, Ashwagandha, Shanka pushpi, and Gotu kola – as well as their plant extracts for possible treatment of Alzheimer’s disease. All samples manifest as inhibitors on three different variants of the Aβ peptide: methionine Aβ1–40, Aβ1–40, and Aβ1–42. The main compounds within the nutraceuticals were identified. Since related medicals are known to have reduced negative post- and side-effects and even may introduce further positive health impacts by preventing pathogen plaque formation and reducing free Aβ to a natural level, such treatment approaches could be of further interest.

Authors: Zupanic Eva , Kramberger Milica G. , von Euler Mia , Norrving Bo , Winblad Bengt , Secnik Juraj , Fastbom Johan , Eriksdotter Maria , Garcia-Ptacek Sara
Published: December 2019

Background:

Recurrent ischemic stroke (IS) increases the risk of cognitive decline. To lower the risk of recurrent IS, secondary prevention is essential.

Objective:

Our aim was to compare post-discharge secondary IS prevention and its maintenance up to 3 years after first IS in patients with and without Alzheimer’s disease and other dementia disorders.

Methods:

Prospective open-cohort study 2007–2014 from the Swedish national dementia registry (SveDem) and the Swedish national stroke registry (Riksstroke). Patients with dementia who experienced an IS ( n = 1410; 332 [23.5%] with Alzheimer’s disease) were compared with matched non-dementia IS patients ( n = 7150). We analyzed antiplatelet, anticoagulant, blood pressure lowering, and statin treatment as planned medication initiation at discharge and actual dispensation of medications at first, second, and third year post-stroke.

Results:

At discharge, planned initiation of medication was higher in patients with dementia compared to non-dementia patients for antiplatelets (OR with 95% CI for fully adjusted models 1.23 [1.02–1.48]) and lower for blood pressure lowering medication (BPLM; 0.57 [0.49–0.67]), statins (0.57 [0.50–0.66]), and anticoagulants (in patients with atrial fibrillation – AF; 0.41 [0.32–0.53]). When analysis for antiplatelets was stratified according to the presence of AF, ORs for receiving antiplatelets remained significant only in the presence of AF (in the presence of AF 1.56 [1.21–2.01], in patients without AF 0.99 [0.75–1.33]). Similar trends were observed in 1st, 2nd, and 3rd year post-stroke.

Conclusions:

Dementia was a predictor of lower statin and BPLM use. Patients with dementia and AF were more likely to be prescribed antiplatelets and less likely to receive anticoagulants.

Published: December 2019

Background:

Amyloid-β positivity (Aβ+) based on PET imaging is part of the enrollment criteria for many of the clinical trials of Alzheimer’s disease (AD), particularly in trials for amyloid-targeted therapy. Predicting Aβ positivity prior to PET imaging can decrease unnecessary patient burden and costs of running these trials.

Objective:

The aim of this study was to evaluate the performance of a machine learning model in estimating the individual risk of Aβ+ based on gold-standard of PET imaging.

Methods:

We used data from an amnestic mild cognitive impairment (aMCI) subset of the Alzheimer’s Disease Neuroimaging Initiative (ADNI) cohort to develop and validate the models. The predictors of Aβ status included demographic and ApoE4 status in all models plus a combination of neuropsychological tests (NP), MRI volumetrics, and cerebrospinal fluid (CSF) biomarkers.

Results:

The models that included NP and MRI measures separately showed an area under the receiver operating characteristics (AUC) of 0.74 and 0.72, respectively. However, using NP and MRI measures jointly in the model did not improve prediction. The models including CSF biomarkers significantly outperformed other models with AUCs between 0.89 to 0.92.

Conclusions:

Predictive models can be effectively used to identify persons with aMCI likely to be amyloid positive on a subsequent PET scan.
Time Reversed Delay Differential Equation Based Modeling of Journal Influence in An Emerging Area
Authors: Mathur Archana , Saha Snehanshu , Sarkar Poulami , Kar Saibal , Basak Suryoday
Published: December 2019

A recent independent study resulted in a ranking system which ranked Astronomy and Computing (ASCOM) much higher than most of the older journals highlighting its niche prominence. We investigate the notable ascendancy in reputation of ASCOM by proposing a novel differential equation based modeling. The modeling is a consequence of knowledge discovery from big data-centric methods, namely L1-SVD. The inadequacy of the ranking method in explaining the reason behind the growth in reputation of ASCOM is reasonable to understand given that the study is post-facto. Thus, we propose a growth model by accounting for the behavior of parameters that contributes to the growth of a field. It is worthwhile to spend some time in analyzing the cause and control variables behind rapid rise in reputation of a journal in a niche area. We intend to identify and probe the parameters responsible for its growing influence. Delay differential equations are used to model the change of influence on a journal’s status by exploiting the effects of historical data. The manuscript justifies the use of implicit control variables and models those accordingly demonstrating certain behavior and patterns in the journal influence.
Galois Lattices-based Formal Design Concept Analysis for Crowdsourcing Design
Authors: Kim Jihoon , Kim Kyoung-Yun
Published: December 2019

Recently, design is supported by crowdsourcing. The vast knowledge generated and contributed by crowds enhances a wide exploration of design ideas. However, limited amount of information called ‘scarcity’, non-guaranteed quality of contributions, and similar contributions made by unspecified participant groups make it difficult to systematically analyze and reuse the design concepts. This paper presents a formal analysis method for design concepts generated by crowdsourcing design activities. To enable the formal design concept analysis, design feature taxonomy is first developed by considering crowdsourcing design environment. In this taxonomy, various design features and participant evaluation features are constructed. Galois lattices-based formal concept analysis is employed as a design concept analysis method. The pivot power case is used to show that the presented method is applicable to a practical crowdsourcing design environment. Finally, precision and recall tests are conducted through a focus group interview and the results from the design analysis without and with the participant evaluation are compared.

Authors: Trubitsina O. P. , Bashkin V. N.
Published: December 2019

The article is devoted to the consideration of geopolitical challenges for the analysis of geoenvironmental risks (GERs) in the hydrocarbon development of the Arctic territory. Geopolitical risks (GPRs), like GERs, can be transformed into opposite external environment factors of oil and gas industry facilities in the form of additional opportunities or threats, which the authors identify in detail for each type of risk. This is necessary for further development of methodological base of expert methods for GER management in the context of the implementational proposed two-stage model of the GER analysis taking to account GPR for the improvement of effectiveness making decisions to ensure optimal operation of the facility oil and gas industry and minimize the impact on the environment in the geopolitical conditions of the Arctic.

Authors: Vasilieva E. V. , Gaibova T. V.
Published: December 2019

This paper describes the method of project risk analysis based on design thinking and explores the possibility of its application for industrial investment projects. Traditional and suggested approaches to project risk management have been compared. Several risk analysis artifacts have been added to the standard list of artifacts. An iterative procedure for the formation of risk analysis artifacts has been developed, with the purpose of integrating the risk management process into strategic and prompt decision-making during project management. A list of tools at each stage of design thinking for risk management within the framework of real investment projects has been proposed. The suggested technology helps to determine project objectives and content and adapt them in regards to possible; as well as to implement measures aimed at reducing these risks, to increase productivity of the existing risk assessment and risk management tools, to organize effective cooperation between project team members, and to promote accumulation of knowledge about the project during its development and implementation.

The analysis of the method of reducing gas obtaining by natural gas air reforming with cooling and drying of obtained products on the first stage of the process, their heat treatment in the catalyst layer, chilling and drying — on the second stage is made. It is determined that the temperature of a thermal gas treatment at the second stage of the process, shall not be less than 850–950 °C, which allows to increase the ratio (CO + H2)/CO2 in the resulting reducing gas. The values of the minimum temperature of gas processing on the second stage of the process depending on the pressure in the system are calculated. The total heat effect of chemical reactions depending on the temperature of gas heat treatment at different pressure is defined. It is shown the possibility of compensation for the heat expenditure required for the chemical reactions behavior in the temperature region above 850 °C by gas overheating in excess of the required level prior to its entering into catalyst bed on the second stage of the process.

En el presente trabajo se realizó una evalución de la preparación superficial de sustratos metálicos con chorro de alumina (sandblasting SB) y mediante el uso de herramientas de corte (HC) sobre aceros inoxidable AISI 304 para después aplicar un recubrimiento por APS. Se utilizo la estacion de rugosidad de la Universidad Nacional de Colombia Sede Medellin con el apoyo del grupo GTS de superficies, para analizar la textura y asi comparar los perfiles de rugosidad y sus respetivos parametros de rugocidad tomando de referencia los parametros más usados en contexto metalmecanico nacional. Como resultado de ejecutar ambas tecnicas sobre inoxidable 304, se evidencio que existe un efecto significativo en la activacion superficial cuando se combinan el sandblasting y los procesos de mecanizado para activar la superficie ya que la componente polar de energia libre disminuye de manera significativa al aumentar las variables de rugosidad.

En la actualidad, la informática ha ayudado en la implementación de soluciones en la gestión de mantenimiento de equipos, facilitando la realización de tareas y reduciendo los costes de forma considerable, por lo cual, se implementa  el desarrollo de una herramienta de software para dar solución al problema de gestión de los procesos de mantenimiento de infraestructura del Servicio Nacional de Aprendizaje - SENA  Regional Antioquia, ya que anteriormente estos se solicitaban a través de trámites engorrosos, usando formatos de Excel, documentos de Word y el correo electrónico continuamente, dificultando  la trazabilidad, la asignación óptima de los recursos humanos y técnicos a la hora de realizar los correctivos pertinentes. La aplicación web de gestión desarrollada minimiza los tiempos improductivos del personal, permitiendo a la organización optimizar recursos humanos, económicos y ambientales al mejorar la atención de aquellos problemas y requerimientos que pueden prevenirse mediante un mantenimiento efectivo y adecuado. Además, esta herramienta aporta al desarrollo sostenible por medio de la minimización del papel, dado que a través de alertas y notificaciones en línea evita la impresión física de los formatos para cada fase del proceso y simplifica las estadísticas, pues se pueden conocer con certeza las operaciones realizadas en un lapso de tiempo determinado; un control y seguimiento preciso de estos procesos es vital para cualquier empresa u organización que posea bienes o inmuebles que requieren mantenimiento periódico

Los procesos de globalización a los que se enfrenta el sector agropecuario en Colombia conllevan una etapa de reestructuración para ser más competitivos y llegar a nuevos mercados, dado que los consumidores hoy en día son cada vez más informados y exigentes en cuanto a la calidad esperada de los productos. Esto lleva a que las empresas sean más eficientes e innovadores en los procesos de producción y comercialización, así como en la diversificación de sus portafolios de productos y mercados. Sin lugar a duda, éste es uno de los mayores desafíos enfrentados por el sector agro en Colombia y para ello se requiere un incremento de las tasas actuales de inversión, favoreciendo el impulso tecnológico y ofreciendo atención prioritaria a la búsqueda y adopción de nuevas alternativas de financiación. En este artículo se resalta el potencial de Colombia en la producción de plátano y se hace énfasis en la necesidad de contar con mecanismos innovadores de financiación para afrontar los problemas actuales de escasez de recursos económicos. Para ello se propone la financiación de productores de plátano a través de la Titularización, con el fin de fortalecer la competitividad del sector y poder aumentar su participación en las exportaciones colombianas.
