Space botany in Lithuania. II. Study on root gravity sensing during satellite “Bion- 11” flight / Kosminė botanika Lietuvoje. II. Šaknų gravitacijos jutimo tyrimas palydovo „Bion-11“ skrydžio metu
Authors: Švegždienė Danguolė
Published: January 2017

This paper addresses the space experiments performed on board of the unmanned satellite “Bion-11” in 1997. To detail root gravity sensing in stimulus-free microgravity environment, researchers from the Institute of Botany developed an automatically operating centrifuge “Neris-8” to grow garden cress seedlings and to chemically fix them at the end of the experiments. There was examined behaviour of gravity sensors - amyloplasts within cap cells of roots responding to stimulation by artificial fractional gravity. The static of amyloplasts was determined in roots after continuous growth for 25 h in microgravity, 0.005, 0.02, 0.1 and 1-g environment. The movement kinetics of amyloplasts was studied in roots during the exposition to microgravity after 24-h growth in 1-g environment or conversely. Quantitative study on the patterns of positioning and movement of plastids was performed by light microscopy. The results obtained led us to detail a mode of gravity sensing by roots in which the interactions between moving amyloplasts, cytoplasm and cytoskeleton were discussed.
Nursing in front of homeless problem in Poland
Authors: Raszka Szymon , Franek Grażyna , Nowak-Kapusta Zofia
Published: January 2017

Introduction. A nurse in her profession meets different kind of people from all society levels. Not once she stands in front of a homeless patient and the dillemma about the sense of helping, which indeed is often “wasted”. Nonetheless the mission of this profession demands the need of seeing a human being in every patient who needs help. Homelessness is marked with a number of stereotypes and marginalisation which is very hard to overcome by oneself and provide the services on the highest level.

Aim. The aim of this work is to outline the cause of homelessness and to set out the role of nurse working with a homeless patient.

Material and methods. In the analysis has mainly been used Polish literature of the subject written by distinguished theoreticians and researchers of this matter. There has also been used data from Central Office of Statistics. In addition, this work has been enriched by personal work experience with the homeless by one of the authors.

Results. In the analysed literature an answer was being looked for following questions: What are the causes of homelessness? What are the ills of homelessness? What is the characteristic of a homeless patient? What is the -professional role of the nurse working with homeless? The role of nursing, in this society, is essential and it demands wide Education. The nurse is sometimes the only person who can provide professional medical and therapeutical help to the homeless. One can rely only on its own abilities and skills, experiencing very often a feeling of helplessness. Following work should help in understanding the essence of homelessness in the way that homelessness itself becomes an extra reason to bring help.

Published: January 2017

Article 4, (1) Act of 15 July 2011 on the Professions of Nurse and Midwife specifies that the profession of a nurse encompasses providing health services. Point 6 specifies the kind and scope of attendance benefits, both for the patient and the care provider. It needs emphasizing that there is a statutory possibility of determining these benefits by nurses, understood as an opportunity to express a professional opinion related to specialized professional activities. This very study will both present and discuss an opinion that was created as a reference to the quoted article. The opinion is related to the scope, types and methods of performing nursing activities for the patient-plaintiff looking to receive a compensation from a healthcare entity. The document created during the process was used by the general court in the pending civil proceeding.

The description that was created took the form of an established standard of care. It defines the specificity, tasks and the amount of time that every nurse needs to spend caring for a patient who is bed-bound. The opinion was created to be used during court proceedings and can be applied to similar cases. This may establish it as a source of medical knowledge in case of recommended and desired scope care exercised by nurses, physiotherapists and paramedics.
Approximating the Added Resistance Coefficient for a Bulk Carrier Sailing in Head Sea Conditions Based on its Geometrical Parameters and Speed
Authors: Cepowski Tomasz
Published: January 2017

The article presents the mathematical function to calculate the added wave resistance transfer function for bulk carriers. Based on this function, the statistical mean added wave resistance generated by an irregular head wave with arbitrary statistical parameters can be forecasted. The input parameters are: waterplane area, waterplane coefficient, ship speed, and frequency of the regular wave. The model has been developed based on the theory of artificial neural networks. The presented function can be used in design analyses, and for planning shipping routes in situations when basic geometrical parameters of the hull are only available and not the full technical documentation. The article presents sample cases of use of this function to calculate the added wave resistance transfer function and the statistical mean added wave resistance. Another presented application refers to waterplane coefficient optimisation taking into account the added wave resistance at the stage of preliminary bulk carrier design.
Approaches to training in companies
Authors: Magnoler Patrizia , Pacquola Mariachiara
Published: January 2017

The need to address generational change and the challenges of a global market in terms of maintaining productivity require small and medium enterprises, mainly of an artisanal nature, to rethink training. The challenges mainly concern production capacity, which is increasingly problematic given that demand does not allow for long-term schedules and enhancement of human resources. There are many tensions and just as many needs for improvement, and training is therefore the space in which to collect and rework in order to restore a new perspective of sustainable and quality change.

This study presents a process of collaboration between universities and businesses, in which the former provide the framework for the activation of mechanisms that make use of work analysis, while the latter provide the appropriate support (time and opportunities for discussion) to allow for a review of the proposed training model and trainer functions in a dynamic and complex production environment.
A shorter proof of the distance energy of complete multipartite graphs
Authors: So Wasin
Published: January 2017

Caporossi, Chasser and Furtula in [Les Cahiers du GERAD (2009) G-2009-64] conjectured that the distance energy of a complete multipartite graph of order n with r ≥ 2 parts, each of size at least 2, is equal to 4(n − r). Stevanovic, Milosevic, Hic and Pokorny in [MATCH Commun. Math. Comput. Chem. 70 (2013), no. 1, 157-162.] proved the conjecture, and then Zhang in [Linear Algebra Appl. 450 (2014), 108-120.] gave another proof. We give a shorter proof of this conjecture using the interlacing inequalities of a positve semi-definite rank-1 perturbation to a real symmetric matrix.

Authors: Aversa Patrizia , Donatelli Antonio , Piccoli Giuseppe , Luprano Vincenza Anna Maria
Published: January 2017

Although the designed theoretical value of U can be derived from the thermal parameters of layers composing an opaque element, according to ISO 6946:2007, measurements are necessary to confirm the expected behaviour. Currently, the measurements of thermal transmittance based on Heat Flow Meter method (HFM) and according to standard ISO 9869-1:2014 are widely accepted. Anyway, some issues related to difficulties in measurements are present: the roughness of wall surfaces, the proper contact between the heat flow plate and the temperature probes with wall surfaces, undesired changes in weather conditions. This work presents the results obtained in thermal transmittance measurements with a modified HFM method, widely described in this paper. Differences between U-values obtained with the modified HFM method and theoretical ones were in the range 0.6 - 6.5 %. Moreover, the modified HFM method provided a result closer to the theoretical one, when compared to that obtained with standard HFM method (discrepancy with theoretical value were 0.6% and 16.4%, respectively).

Authors: Zaggelidis Georgios
Published: January 2017

The specificity of the technical performance in judo and karate demands from athletes to perform fast and powerful actions at a high level, therefore, much importance is given to the development and supporting motor system, in particular, HGS function. Research aim was to determine the characteristic of maximal isometric HGS in Greek elite male judo and karate kumite athletes that may be important for competitive success in the aspect of age and BMI and identify any differences between these two compact sports. The studies were carried out in the competitive period of 2015 training cycles. The subjects were male judokas with mean weight 84.24 ± 12.38 kg and karateka’s 76.63 ± 10.46 kg. Average BMI (kg/m2) for judokas 25.67± 3.60 and karateka’s 23.03 ± 1.75. Research results showed that the HGS in dominant and nondominant hand in karateka’s was 68.28 ± 7.3 kg and 63.28 ± 7.5 kg and in judokas 73.72 ± 7.85 kg and 71.34 ± 8.10 kg. karateka’s had significant less stronger HGS compered to Judokas in dominant and nondominant hand, t32= -2.089 and p<0.05 and t32= -3.016 and p<0.05. Karateka’s had significant higher differences between the two hands 4.94 ± 2.15 kg compered to judokas 2.38 ± 1.84 kg, t32= 3.722 and p<0.05. The two groups had significant difference in BMI, t32= -2,771 and p<0.05. Pearson correlation showed a significant correlation between HGS and BMI, r=0.563 and p<0.05. In conclusion judo and karate have different requirements and training methods due to the objectives and generally the technical training nature with judokas appearing stronger in the HGS compere to karateka’s.
T-Superiority and T-Norm-Based Images of Fuzzy Sets
Authors: Bodjanova Slavka , Kalina Martin
Published: January 2017

Comparisons of finite fuzzy sets based on the results of conjunctive and disjunctive aggregations of their membership grades are studied. For a given t-norm T, the notion of T-superiority of fuzzy sets is introduced. When a fuzzy set g is T-superior to a fuzzy set f, the description of a vague concept by g is much more desirable than the description by f. For a comparison of a fuzzy set f with the “standard” fuzzy set g (describing the desirable or historically the most common characterization of the vague concept in question) t-norm-based transformations of f with respect to g, called the T-images of f, are suggested. A special type of the T-image of f with respect to g may be considered as a soft evaluation of T-superiority of g to f.

Authors: Dulksnienė Liudmila , Stankevičienė Sigutė , Ramanauskas Irmantas , Šarkauskienė Laima
Published: January 2017

The changing approach to a physician’s profession brings about changes in the professional education and training of family physicians as well as in their continuous qualification improvement. For this reason, during the reformation of Lithuania’s primary healthcare system, not only alterations in family physicians’ activity, but also the changes in their education and training and the updating and improvement of their curriculum were seen as priority areas.

The aim of the study was to reveal and compare resident physicians’ attitude to the peculiarities of the professional education and training of family physicians based on the traditional and problem-based learning systems at the Lithuanian University of Health Sciences (subsequently, LSMU).

The study on the professional education and training of family physicians was conducted in 2005 and in 2015. The quantitative study was carried out via a written questionnaire survey. The studied population consisted of resident physicians who were studying family medicine at the LSMU.

The analysis of the peculiarities of the professional education and training of family physicians showed that resident physicians acquired sufficient knowledge and skills in the fields of disease diagnostics and treatment, qualification improvement, disease prevention, and teamwork organization. Resident physicians had insufficient skills to adapt to new conditions of activity, and their studies did not develop creative thinking. The problem-based learning (PBL) system helps future family physicians to develop essential competences and to acquire knowledge and skills required for the career of a family physician.
Patients with Multimorbidity and Their Experiences with the Healthcare Process: A Scoping Review
Authors: van der Aa Maartje J. , van den Broeke Jennifer R. , Stronks Karien , Plochg Thomas
Published: January 2017

Background

The number of patients with multimorbidity (two or more conditions) is increasing. Observational research has shown that having multiple health problems is associated with poorer outcomes in terms of health, quality of care, and costs. Thus, it is imperative to understand how patients with multimorbidity experience their healthcare process. Insight into patient experiences can be used to tailor healthcare provision specifically to the needs of patients with multimorbidity.

Objective

To synthesize self-reported experiences with the healthcare process of patients with multimorbidity, and identify overarching themes.

Design

A scoping literature review that evaluates both qualitative and quantitative studies published in PubMed, Embase, MEDLINE, and PsycINFO. No restrictions were applied to healthcare setting or year of publication. Studies were included if they reported experiences with the healthcare process of patients with multimorbidity. Patient experiences were extracted and subjected to thematic analysis (interpretative), which revealed overarching themes by mapping their interrelatedness.

Results

Overall, 22 empirical studies reported experiences of patients with multimorbidity. Thematic analysis identified 12 themes within these studies. The key overarching theme was the experience of a lack of holistic care. Patients also experienced insufficient guidance from healthcare providers. Patients also perceived system-related issues such as problems stemming from poor professional-to-professional communication.

Conclusions

Patients with multimorbidity experience a range of system- and professional-related issues with healthcare delivery. This overview illustrates the diversity of aspects that should be considered in designing healthcare services for patients with multimorbidity.
Effect of β-agonist on the dexamethasone-induced expression of aromatase by the human monocyte cells
Authors: Watanabe Masatada , Ohno Shuji , Wachi Hiroshi
Published: January 2017

Emerging evidence suggests that sex steroids are important for human skin health. In particular, estrogen improves skin thickness, elasticity and moisture of older women. The major source of circulating estrogen is the ovary; however, local estrogen synthesis and secretion have important roles in, for example, bone metabolism and breast cancer development. We hypothesized that infiltrated peripheral monocytes are one of the sources of estrogen in skin tissues. We also hypothesized that, during atopic dermatitis under stress, a decline in the hypothalamus–pituitary–adrenal axis (HPA) and facilitation of the (hypothalamus)–sympathetic–adrenomedullary system (SAM) attenuates estrogen secretion from monocytes. Based on this hypothesis, we tested aromatase expression in the human peripheral monocyte-derived cell line THP-1 in response to the synthetic glucocorticoid dexamethasone (Dex), the synthetic β-agonist isoproterenol (Iso) and the β-antagonist propranolol (Pro). Dex mimics glucocorticoid secreted during excitation of the HPA, and Iso mimics catecholamine secreted during excitation of the SAM. We found that aromatase activity and the CYP19A1 gene transcript were both upregulated in THP-1 cells in the presence of Dex. Addition of Iso induced their downregulation and further addition of Pro rescued aromatase expression. These results may suggest that attenuation of estrogen secretion from peripheral monocytes could be a part of the pathology of stress-caused deterioration of atopic dermatitis. Further examination using an in vitro human skin model including THP-1 cells might be a valuable tool for investigating the therapeutic efficacy and mechanism of estrogen treatment for skin health.
Using corpora to track changing thought styles: evidentiality, epistemology, and Early Modern English and German scientific discourse
Authors: Whitt Richard J.
Published: January 2017

Most research on evidentiality has focused on classifying evidential systems synchronically; meanwhile, diachronic studies on evidentiality seem to have focused on the development of specific items into evidential markers with little regard to discourse context. This paper begins to fill this gap by presenting the results of a corpus-based study of evidential markers in Early Modern scientific discourse in English and German. The Early Modern period witnessed the transition from scholastic-based models of science to more empirical models of enquiry; this study demonstrates a decrease in the use of markers of mediated information and an increase in the use of markers of direct observation and inference accompanying these sociohistorical developments.

Published: January 2017

Objectives

Sleep disturbances are related to somatic and mental disorders, industrial accidents, absenteeism, and retirement because of disability. We aimed to identify health-related behaviors associated with subjective sleep insufficiency in Japanese workers.

Methods

This cross-sectional study included 5,297 employees (mean age: 43.6±11.3 years; 4,039 men). Multiple logistic regression analysis was used to identify health-related behaviors associated with subjective sleep insufficiency.

Results

Overall, 28.2% of participants experienced subjective sleep insufficiency. There was a significant difference between the genders in the proportion of participants with subjective sleep insufficiency (male: 26.4%; female: 34.3%; p<0.001). Multiple logistic regression analysis revealed that being a female or ≥40 years, experiencing a weight change of ≥3 kg during the preceding year, not exercising regularly, not walking quickly, and eating a late-evening or fourth meal were associated with subjective sleep insufficiency. After stratifying by gender, age ≥40 years, not exercising regularly, and eating a late-evening or fourth meal were significantly associated with subjective sleep insufficiency in both genders. Not walking quickly, experiencing a weight change, and eating quickly were positively associated with subjective sleep insufficiency only for males. Females who did not engage in physical activity were more likely to have experienced subjective sleep insufficiency, but this relationship was not observed in males.

Conclusions

The results indicated that certain health-related behaviors, specifically not exercising regularly and nocturnal eating habits, were associated with subjective sleep insufficiency in a group of Japanese workers.

Corpoica Guayuriba 9: new improved soybean (Glycine max [L] Merril) variety with specific adaptation to the Colombian foothills
Authors: Caicedo Guerrero Samuel , Tibocha Ardila Yuli , Campuzano Duque Luis Fernando
Published: January 2017

Soybean in Colombia is constituted, like corn, as the main raw material for the production of balanced concentrates for animal feeding. The national soybean production satisfies only 7.0% of the demand for poultry-swine chain, with imports in 2014 of 363501 tons of grain and 1018256 tons of soybean meal. Currently, in Colombia, soybean is only produced in the Orinoquia region, mainly in the high plains and foothills and is part of the rice-corn-soy rotation system for the colonization of native savannas. In order to promote cultivation which allows the occupation of 500000 potentially hectares in the foothills with new varieties beyond current and meet domestic demand, Corpoica is responsible for the plant breeding. As a result of a research in plant genetic resources during nine years (2006-2014), the study of a group of elite soybean genotypes on two contrasting regions: high plains and foothills. In addition, main components analysis per genotype-location interaction were determined for L-189 genotype identified with specific adaptation to the foothills and the highest experimental yield of 2660 k.ha-1, superior in more than half a ton to the yield obtained by the control varieties (P-34 and Superior 6); with traits which bring competitive advantages such as a larger number of pods per plant (56) and smaller seeds (15.2g), besides an acquired tolerance to the Cercospora sp. pathogen.
Modelling effective soil depth at field scale from soil sensors and geomorphometric indices
Authors: Castro Franco Mauricio , Domenech Marisa , Costa José Luis , Aparicio Virginia Carolina
Published: January 2017

The effective soil depth (ESD) affects both dynamic of hydrology and plant growth. In the southeast of Buenos Aires province, the presence of petrocalcic horizon constitutes a limitation to ESD. The aim of this study was to develop a statistic model to predict spatial patterns of ESD using apparent electrical conductivity at two depths: 0-30 (ECa_30) and 0-90 (ECa_90) and geomorphometric indices. To do this, a Random Forest (RF) analysis was applied. RF was able to select those variables according to their predictive potential for ESD. In that order, ECa_90, catchment slope, elevation and ECa_30 had main prediction importance. For validating purposes, 3035 ESD measurements were carried out, in five fields. ECa and ESD values showed complex spatial pattern at short distances. RF parameters with lowest error (OOBerror) were calibrated. RF model simplified which uses main predictors had a similar predictive development to it uses all predictors. Furthermore, RF model simplified had the ability to delineate similar pattern to those obtained from in situ measure of ESD in all fields. In general, RF was an effective method and easy to work. However, further studies are needed which add other types of variables importance calculation, greater number of fields and test other predictors in order to improve these results.

Yotoco Nature Reserve is a protected area for conservation purposes, is located at 3o53'18'' N, 76o20'5'' W, in the town of Yotoco with an altitude of 1526 m. a. s. l. The present research aimed to identify the diversity of mite suborder Prostigmata associated with the rhizosphere of plants of the Natural Reserve of Yotoco. Six samplings of soil and leaf litter between the surface and 5 cm depth were done in a radius of 1 m from the stem of plants, which are representative in each location of study. Samples were taken to the laboratory in styrofoam coolers. To isolate the mites, the Berlese-Tulgren funnel was used and mites were collected in vials with 70% alcohol. For permanent mounting in microscope slides, the Hoyer medium was used. A completely randomized block design with stratified replicates was used. The total of collected individuals was 181 and they were distributed in the following mite families: Microtrombidiidae, Stigmaeidae, Cunaxidae, Bdellidae, Pseudocheylidae, Cryptognathidae, Eupalopsellidae and Scutacaridae. The Stigmaeidae family was the most abundant and frequent. Among the identified mite families, 15 genera were found, from which, the genera Stigmaeus Koch, 1836 was the most common.

Published: January 2017

Guarianthe skinneri (Bateman) Dressler & W.E. Higgins., is a native orchid from Mexico, considered as threatened species by NOM-ECOL-059-SEMARNAT-2010, mainly due to the disappearance of its natural habitat and the illegal collection during its flowering season. The aim of this research was to induce in vitro callogenesis from different type of explants, using phytoregulators, in order to look for a massive production technique to contribute to its conservation. We evaluated the leaf and pseudobulb marrow explants growing in semi-solid medium MS adding BAP, 2, 4-D, Kin, the interaction of BAP/2, 4-D/Kin/Sad and a control without any type of plant growth regulators. Statistical analysis showed the pseudobulb marrow explants are more suitable for in vitro introduction in comparison to leaf explants, since they perform a lower percentage of contamination (18.8% in marrow and 73.2% in leaves). Likewise, the pseudobulb marrow explants increased callus formation (10.8%) in comparison to leaf explants (7.6%). Regarding the phytoregulators employed, BAP have allowed to increased callus formation (17%) compared to other phytoregulators (7-10%). This is the first report, which proposes the use of pseudobulb marrow as explant for callus induction in G. skinneri.

¿Qué tienen que ver los proyectos de Archigram, los metabolistas japoneses o los integrantes del Team X con los programas de vivienda económica que se desarrollaron en Chile durante el período de acción de la Corporación de la Vivienda? Aparentemente nada. Mientras los primeros se han explicado a partir de las relaciones de la arquitectura con el arte, el problema habitacional de los sectores populares ha sido abordado principalmente como un asunto político, técnico, social y económico.Sin embargo, hay un punto de contacto entre estas propuestas, al parecer tan distintas: la idea de que había una dimensión de la forma que podía ser proyectada, estabilizada y otra que no, que se dejaba para que fuera practicada, gestionada y decidida por los usuarios. El presente artículo propone una lectura crítica de algunos programas habitacionales chilenos, como las Erradicaciones y la Operación Sitio, a partir del problema de la estabilidad e inestabilidad de la forma.

The Roma response to development strategies: A replicate model for collective action and inclusive development in a Hungarian village
Authors: Mishra Malay , Karunanithi Gopalakrishnan
Published: January 2017

The paper deals with seminal changes in the socio-economic life of the Roma community in the village of Cserdi in Hungary, brought about by a host of strategic programs of a dynamic Roma Mayor. It suggests several measures to develop a viable development model by consolidating his programs with a few modifications to suit the Roma, who constitute the majority population in the village, as well as their counterparts living elsewhere in Hungary and Central and Eastern Europe. It also illustrates how such a model has proven to be a successful strategy in developing and empowering marginalized groups in India, while arguing its efficacy for the Roma situation in Hungary.

Abstract:

Introduction: It is known that the quality of life (QoL) of patients surgically treated for head and neck cancer (HNC) is significantly enhanced by rehabilitation. It is also known that some of these patients will not quit smoking. Aim: To assess if smoking hampers rehabilitation-related QoL enhancement after surgery. Method: Applying the H&N 35 questionnaire of EORTC, we assessed the QoL of 38 smoking and non-smoking patients who underwent surgical therapy for HNC and subsequent rehabilitation. QoL was assessed after surgery (after the healing period) and 6 months after rehabilitation. Results: While the QoL enhancement of nonsmokers was significant in almost all aspects, that of smoking patients did not reach the level of significance on a number of scales. The results suggest that smoking does not hamper rehabilitation directly, rather, it prevents rehabilitation from exerting its beneficial effects through its own effects. Conclusions: Smoking is a factor that measurably acts against the efforts to enhance the QoL of the surgically treated HNC patient. Therefore, it is essential that emphasis is put on smoking cessation right from the cancer diagnosis also for this reason. Orv. Hetil., 2017, 158(5), 172–177.

Having graduated not at the right time is a common phenomena among college students and  procrastinantion which is delaying the final assignment become the reason. One of factors that affect  procrastination is self-efficacy. Self-efficacy that is predicting academic achievement is academic self-efficacy. This research uses quantitative methods to examine the relationship between academic self-efficacy and academic procrastination among 210 students who are completing the last assignment. Instrument used are academic procrastination scale and academic self-efficacy scale. Result shows that there is no significant correlation between academic self-efficacy and academic procrastination among students who were completing the last assignment (r = -0.059, p = 0.398). Besides, academic procrastination had significant differences by age, gender, year of admission, residence, and activities. In the same time, the academic self-efficacy had differences by age, year in, obstacles and activities.

Factors influencing gastroenterology specialist trainees’ satisfaction with the regional speciality educational programme
Authors: Beales Ian
Published: January 2017

This article was migrated. The article was marked as recommended. All post-graduate training programmes in the United Kingdom follow relevant competency-based curricula. Whilst much of trainees learning occurs during the day-day activities of their training posts, all training programmes support their trainees with a formal taught educational programme, usually based on full or half-days of education for all trainees on that training scheme. The factors which influence trainees learning and satisfaction with these educational programmes have not been examined. The factors associated with increased trainee- perception of high teaching quality and the effect on practice from all regional teaching sessions over a 6 year period were examined in the East of England Gastroenterology training scheme. There was a very strong correlation between perceived teaching skills of the educator and the scores for effect on practice. Teacher and curriculum factors associated with higher scores for effect on practice were examined by unconditional logistic regression. Overall two teacher-related factors were independently associated with highest scores for effective teaching: having a formal post-graduate educational qualification and having published a paper on the relevant topic in the last 12 months. No curriculum-related factors were related to the perceived qualify of the teaching session. These data provide some insight into factors that should be considered when designing regional speciality teaching programmes and emphasize that educational qualifications appear to be a very important marker of high-quality teaching.

Published: January 2017

The structural performance of reinforced-concrete (RC) beams can be enhanced by introducing various types of randomly dispersed discrete fibres into the concrete matrix. While the shear behaviour of steel fibre RC beams has been studied substantially, research focusing on the shear behaviour of polypropylene fibre RC beams is limited. In the study reported here, the influence of polypropylene fibres on the shear behaviour of RC beams without stirrups was experimentally investigated. The test specimens comprised two RC beams and nine polypropylene fibre RC beams. The main test variables were the shear span-to-effective depth ratio and the volume fraction of polypropylene fibres. The beams were tested under a concentrated load at mid-span. It was found that both the shear strength and ductility of the beams were improved by adding polypropylene fibres, but the addition of polypropylene fibres even at 3% by volume was not able to change the failure mode for beams with shear span-to-effective depth ratios of 2·5 and 3·5. Based on an evaluation of the experimental results, a previously proposed equation for predicting the shear strength of steel fibre RC beams without stirrups was revised to predict the shear strength of polypropylene fibre RC beams without stirrups.
LAS METÁFORAS EN LA INTERVENCIÓN CON PADRES: SU EFICACIA EN LA MEJORA DE LAS RELACIONES FAMILIARES

Published: January 2017

Abstract.Metaphors are a useful resource not only to influence family relationships but to achieve positive changes in parenting behavior. Family intervention is essential in all forms of intervention, to the point that if there are no changes in family systems, it will be very difficult for a counselor or an educational psychologist to have positive effect on children and adolescents. The family often contributes not only in maintaining the problems alive, but also in generating them. Adults immersed in a negatively balanced family system generally also show defensive behaviors induced by emotional distress or unconscious personal insecurity. The use of the metaphor involves the transmission of symbols or anchors, which can serve as an effective tool to control this type of behavior, and is crucial to successful intervention. In this paper, practical examples of different metaphors for parents and their objective in therapy will be presented.Keywords: family intervention, psychology intervention , family relationships, metaphorResumen.En este artículo presentamos la metáfora como un recurso de gran utilidad para incidir tanto en las relaciones familiares como para conseguir cambios de conductas inadecuadas y preocupantes en padres. La intervención familiar es imprescindible en toda intervención psicopedagógica hasta el punto de que si no se producen cambios en los sistemas familiares en los que predominan relaciones sustentadas por equilibrios negativos, es muy difícil que un orientador o un psicólogo educativo pueda contribuir a que se produzcan cambios de conductas problemáticas de menores, adolescentes y/o jóvenes. La familia puede estar contribuyendo no sólo a mantener la problemática sino también a generarla. Los adultos inmersos en un sistema familiar equilibrado negativamente, en general, muestran también conductas defensivas provocadas por un malestar o inseguridad personal inconsciente. El uso de la metáfora que comporta la transmisión de símbolos o anclas que pueden servir de control eficaz para este tipo de conductas es básico y necesario para obtener éxito en la intervención. Es por ello que en el presente artículo se presentan ejemplos prácticos de diferentes metáforas aplicadas en sesiones a padres exponiendo también el objetivo que se pretende conseguir con las mismas.Palabras clave: intervención familiar, intervención psicopedagógica, relaciones familiares, metáfora
