Published: December 2019

Small group learning activities have been shown to improve student academic performance and educational outcomes. Yet, we have an imperfect understanding of the mechanisms by which this occurs. Group learning may mediate student stress by placing learning in a context where students have both social support and greater control over their learning. We hypothesize that one of the methods by which small group activities improve learning is by mitigating student stress. To test this, we collected physiological measures of stress and self-reported perceived stress from 26 students in two undergraduate classes. Salivary cortisol and testosterone were measured within students across five contexts: a) pre-instructional baseline, b) following a traditional lecture, c) after participating in a structured small group learning activity, d) following completion of multiple choice, and e) essay sections of an exam. Results indicate students have lower salivary cortisol after small group learning activities, as compared to traditional lectures. Further, there is no evidence of a relationship between physiological measures of stress and self-reported perceived stress levels. We discuss how structured small group activities may be beneficial for reducing stress and improving student learning outcomes.
Teaching Developmental Theory with Interrupted Video Case Studies
Authors: Anderson Bill
Published: December 2019

This study sought to determine the usefulness of interrupted case studies, utilizing a progressive disclosure of information over time, to increase critical thinking and student learning in the study of foundational theories in the human development field. Apted’s (2013) Up documentary series, consisting of video interviews over a 49-year period, was used as the interrupted study and successfully provided vicarious, but meaningful, opportunities to consistently and authentically apply course content. Participants (N = 23) were students in three sections of a graduate Human Development course where a pre-/post-test format was utilized. The effect was significant as all participant’s posttest score improved an average of 24.3%, F(3, 19) = 3.55, p = .049. Also, coded student work indicated an increase in complex levels of thinking across the 8-week assignment, further validating post-test scores, t(352) = -3.172, p = .002. Evidence from student work further confirmed that an interrupted video case-study, could address limitations typically associated with case-based instruction and, more importantly, provide the critical case-study qualities needed here. Those included, telling a detailed, ambiguous, and real-life story that provided genuine context to connect theory and practice.
Trajektoriengenerator zur Erzeugung beschränkter B-Splines
Authors: Seefried Andreas , Pfeiffer Andreas
Published: December 2019

Der Beitrag stellt einen Algorithmus zur Generierung von mehrfach stetig differenzierbaren Trajektorien auf Basis von B-Splines vor, deren Funktionswerte und Ableitungen innerhalb von konstanten Grenzen liegen. Die Trajektorien können für Systeme genutzt werden, bei denen Grenzen in den Ableitungen des Systemeingangs vorliegen. Dies trifft beispielsweise auf Modelle zu, bei denen ein Antrieb mit Begrenzungen in der Position, Geschwindigkeit und Beschleunigung als Systemeingang genutzt wird.

Zur Generierung werden Parameter, Startwerte der Trajektorie sowie die konstanten Grenzen benötigt. Eine quadratische Optimierung liefert die Stützpunkte der B-Spline-Kurve, die dadurch definiert ist. Die implizit begrenzten B-Splines können ideal in Optimalsteuerungsproblemen und modellprädiktiven Regelungen als Steuertrajektorie eingesetzt werden. Durch die implizite Berücksichtigung von Nebenbedingungen können ebensolche aus dem eigentlichen Optimierungsproblem entfallen. Daraus resultiert eine Verringerung der Komplexität des Optimalsteuerungsproblems bzw. der modellprädiktiven Regelung was wiederum zu einer schnelleren Berechnungszeit führt.

Die implizit begrenzten B-Splines werden im Beitrag vorgestellt und exemplarisch in einer modellprädiktiven Regelung mit einem robotischen System angewandt. Sie führen zu einer deutlich schnelleren Berechnungszeit im Vergleich zur Nutzung von B-Splines mit expliziten Nebenbedingungen im Optimierungsproblem.
Model-based chassis control system for an over-actuated planetary exploration rover
Authors: Barthelmes Stefan , Konigorski Ulrich
Published: December 2019

In planetary exploration, wheeled mobile robots (rovers) are popular for extending action range compared to a lander. Despite their success, they continue to struggle with soft grounds which shows in high sinkage and can lead to an immobilization in the worst case. Rovers usually are over-actuated due to individual wheel drives and steering, which is rarely made use of in current missions. Some work optimizing the resulting degrees of freedom exists but often does not use all available model knowledge. In this work, the rover is consequently modeled with the subsystems rigid body dynamics, kinematics and wheel/ground dynamics. Feedback linearization is used for the rigid body and the underlying wheel/ground controllers on individual wheel level. The control allocation of the forces is done via the pseudo-inverse and a base of the null-space to extract the available degrees of freedom. A verification of the approach is shown in a co-simulation with a high-fidelity model of the ExoMars rover.
Mixing studies for lupus anticoagulant: mostly yes, sometimes no
Authors: Favaloro Emmanuel
Published: December 2019

Lupus anticoagulants (LAs) represent one manifestation of the clinical condition called antiphospholipid syndrome (APS) and are associated with many adverse clinical outcomes, but primarily with thrombosis and/or pregnancy morbidity. LAs are identified by laboratory testing, principally using clot-based assays based on Russell viper venom time (RVVT) and activated partial thromboplastin time (APTT) test methods. All three of the most recent guidance documents for LA testing recommend using these tests, although they vary in regard to inclusion/exclusion of other test processes. Mixing studies form part of the process of LA identification/exclusion, since in vitro LAs act like coagulation inhibitors. Mixing studies are also supported by all three LA guidance documents, but recommendations vary in regard to relative importance and placement in the LA identification/exclusion algorithm. This Point article takes the position that mixing tests are usually indicated for appropriate identification/exclusion of LAs, but can occasionally be omitted.

Authors: Nugrahaningtyas Khoirina Dwi , Rahmawati Nining , Rahmawati Fitria , Hidayat Yuniawan
Published: December 2019

The synthesis of CoMo/Mordenite (CoMo/MOR) catalysts was conducted using a co-impregnation method at a various Co/Mo ratios. The produced catalysts were then characterized by X-ray diffraction, total acidity analysis, and scanning electron microscopy. The activity of the catalyst in a hydrotreatment reaction was evaluated by applying the catalyst as a reduced-catalyst to the hydrocracking (HC) reaction of anisole molecules. Analysis of the diffraction data using the Le Bail refinement technique showed that the metal phase was successfully impregnated into the MOR. In addition, increasing the metal content resulted in an increase in the acidity of the catalysts and changed the morphology of the catalysts from homogeneous to heterogeneous with larger particle size. According to the data of GCMS, it is known that the catalysts successfully removed methyl group of anisole molecules. Hydrotreatment reaction with the prepared-catalyst produced 4.77% of phenols. It is 122 % higher than the reaction with MOR catalyst.

Authors: Song Jitian , Su Hang , Tian Wei , Wang Yening , Feng Yongxia , Liu Jianbo
Published: December 2019

Fresh fruit juice has a short storage period and it usually needs to be concentrated for shelf-life extension. Evaporation of fruit juice is an attractive method and vertical tube falling film evaporator is one of good choice. The main problem in the design of the evaporator is the reliable estimation of the heat transfer coefficient for all effects. In this paper, the effects of feed flow rate, evaporation temperature, temperature difference, and juice soluble solid content on heat transfer coefficient of a vertical falling film evaporator were investigated. The Bayesian treed Gaussian process model was used to identify the key variables affecting the heat transfer coefficient, which showed that evaporation temperature had the greatest influence on the sensitivity of heat transfer coefficient. It also demonstrated that complex interactions existed between the four operating parameters had a significant effect on the overall heat transfer coefficient.
Exploring Faculty Perceptions about Simulation Training: Influence on Career, Confidence, Knowledge and Skill Acquisition and Competence
Authors: Waxman KT , Nichols Amy A. , Shum Cynthia , Forsey Lynn
Published: December 2019

Even with insufficient evidence in the literature regarding the impact of faculty development with simulation education, faculty development is critical to building a successful simulation program. Despite simulation being ubiquitous in nursing education across the United States (US), there is little investigation of the impact of the education and training on job satisfaction, skill development and overall confidence when using simulation to teach nursing students. The purpose of this qualitative study was to investigate how has simulation education and training has influenced faculty career fulfillment, acquisition of knowledge, overall self-confidence and competence? Themes that emerged included the following: competency, professional role change, role acquisition, course learner needs, course impact, skill development, and overall ability and confidence. The study results confirmed that a gap exists where faculty without formal education may not be aware of their lack of competence and what training they need to be effective in facilitating clinical simulation.

Published: December 2019

Aim

To analyze the Socio-emotional (SE) skills of the students in the Nursing Degree, and their relationship with their clinical practice in hospital centers.

Methods

Cross-sectional descriptive study of a sample of 91 nursing students. SE skills were analyzed through self-administered questionnaires, and the clinical practices through the instrument “Clinical Practices Evaluation Notebook”.

Findings

The students obtained medium and high scores in the SE skills and in the clinical practices. Most of the SE skills had a positive and statistically significant relationship (p < 0.05) between them. A relationship was observed between SE skills with performance in clinical practices, through a multiple linear regression.

Discussion

It is suggested that the development of the SE skills of the nursing students within the Nursing degree curriculum has an influence on their performance during their clinical practices.

Conclusion

The SE skills are a potential predictor of the performance of the nursing students in clinical practices.
Mental Imagery and Strength Training: Student Athletes’ Perceptions, Desires, and the Impact of Psychoeducation
Authors: Wallace Alex Francis Xavier , Blom Lindsey C. , Gretton Thomas W.
Published: December 2019

Consistent evidence suggests the effectiveness of mental imagery (MI) for improving strength training performance (STP). However, strength and conditioning (S&C) coaches infrequently encourage use of MI, potentially believing athletes perceive it to be ineffective in supporting STP Additionally, psychoeducation has been found to affect perceptions regarding information presented. The purpose of this study was to assess the perceptions and desires of athletes regarding the effectiveness and use of MI to support STP. The impact of an animated psychoeducation video on perceptions of effectiveness and desires to learn more about MI for STP was assessed as well. 47 NCAA Division I student athletes (various sports; female: n = 34) participated in the pre-post study. Participants’ use of MI, S&C coaches’ encouragement of MI, perceptions of MI effectiveness on STP, and interest in learning more about MI to support STP were initially assessed. Following a two-minute video, participants’ perceptions of MI effectiveness on STP and interest in learning more about MI to support STP were reassessed. Significant increases were found in participants’ perceptions of MI effectiveness to support STP (p < 0.05). No significant changes were noticed regarding athletes’ desires to learn more about MI to support STP. Although potentially uninterested in learning more about MI, student athletes indeed perceive MI to be effective, especially after provided with information. Encouragement of MI by S&C coaches to their student athletes is warranted.
Sincerity in Lithuanian epistolarity: Between truth and emotion
Authors: Tamošiūnaitė Aurelija
Published: December 2019

This paper investigates the lexical representation of sincerity in Lithuanian epistolarity throughout the twentieth century. Drawing on data from the corpus of Lithuanian letters and employing the techniques of corpus, statistical and philological analysis, this paper explores the use, frequency and context of occurrence of the four sets of lexical stems:atvir- (‘open’, ‘frank’),nuošird- (‘sincere’, ‘honest’),šird- (‘heart’), andtikr- (‘authentic’, ‘genuine’, ‘real’). As each of these lexical stems foreground different semantic shades of sincerity, they are treated in this paper as lexical variables that inscribe different degrees of an author’s sincere attitude (stance) toward the addressee and the writing act itself. The findings suggest that in Lithuanian epistolarity the use of sincerity lexemes is constrained by the grammatical shape of the lexeme and genre-related factors, namely, formulaic vs. non-formulaic context. Frequent lexical inscription of sincerity lexemes in the speech acts of thanking, wishing and greeting suggests that sincerity (as a stance) is conventionally linked to these specific social acts. When these social acts are evoked in epistolary practice, they thus evoke a particular (sincere) stance meaning.

Published: December 2019

Along with the studies of the properties of optical microcavities, the optical nonlinear effects of the material and the interaction between light and matter are becoming important topics. For example, the chaotic effect of the optical field may appear under the strong laser pumping due to the nonlinear effects. In this study, the chaotic phenomenon of photonic superposed states is investigated in an optomagnonical cavity. Through the dynamic evolution of two-mode photons in the cavity, we found that the energy of the system could be transferred between different modes, and the chaotic behaviour can be tuned by the coupling and the dissipation.

Published: December 2019

Objective To investigate the clinical efficacy and toxicity of Pemetrexed versus Gefitinib as second-line treatment for advanced non-small cell lung cancer (NSCLC).

Methods By systematically searching the electronic databases of Pubmed, CENTRAL, Cochrane, EMBASE, ASCO, and CBM, open published randomized clinical trials (RCTs) relevant to clinical efficacy and toxicity of Pemetrexed versus Gefitinib as second-line treatment of advanced NSCLC were included in the meta-analysis. Data of objective response rate (ORR) and drug related toxicity were extracted from the original publications and pooled by random or fixed effect method.

Results Fourteen clinical trials related to Pemetrexed versus Gefitinib as second-line treatment for advanced NSCLC fulfilled the inclusion criteria and were included in the meta-analysis. The pooled results show that the ORR (RR=0.81, 95% CI:0.56–1.16, p=0.25) and DCR (RR=1.11, 95% CI:0.94–1.31, p=0.24) were not statistical different for Pemetrexed versus Gefitinib as second-line treatment of advanced NSCLC. However, the pooled data demonstrated the risk of developing skin rash (RR=0.10, 95% CI:0.03–0.30, p=0.00) and diarrhea (RR=0.31, 95% CI:0.15–0.67, p=0.003) in patients with Pemetrexed was significantly lower than that of Gefitinib through random effect model analysis, but the incidence of neutropenia in Pemetrexed group was significantly higher than that of Gefitinib with statistical difference (RR=7.62, 95% CI:3.71–15.66, p=0.00).

Conclusion Pemetrexed was not inferior as second-line treatment for advanced NSCLC compared to Gefitinib for tumor response. However, Pemetrexed had higher incidence of neutropenia but lower risk of developing skin rash and diarrhea.
Race, Blacksound, and the (Re)Making of Musicological Discourse
Authors: Morrison Matthew D.
Published: December 2019

This article highlights practices of exclusion embedded in musicology—especially in relation to race, racialized people, and race relations—in order to rupture its constructed borders and decentralize the normative systems that have come to shape the discipline, its membership, and its discourses. To this end, I define and apply the concept of Blacksound—the sonic and embodied legacy of blackface performance as the origin of all popular music, entertainment, and culture in the United States. Blackface emerged as the first original form of US popular music during chattel slavery, and it helped to establish the modern music industry during the time in which Guido Adler began to define Musikwissenschaft (1885). Blacksound, as the performative and aesthetic complement to blackface, demonstrates how performance, (racial) identity, and (intellectual) property relations have been tethered to the making of popular music and its commercialization since the early nineteenth century. Blacksound also reveals how practices of exclusion that are germane to musicological discourse are connected to the racist practices and supremacist systems that defined society and popular culture throughout the nineteenth century. To redress the impact of these customs, this article defines and employs Blacksound as a means of placing (the performance of) race, ethnicity, and their relationship with other forms of identity at the center of the way we approach and select our subject matter and create musicological epistemologies within the development of music studies.
Capital californiano, necesidad presupuestal y cambio político: Juan Temple y el arrendamiento de la Casa de Moneda de México, 1827–1857
Authors: Herrera Omar Velasco
Published: December 2019

Durante la primera mitad del siglo xix, las necesidades presupuestales del erario mexicano obligaron al gobierno a recurrir al endeudamiento y al arrendamiento de algunas de las casas de moneda más importantes del país. Este artículo examina las condiciones políticas y económicas que hicieron posible el relevo del capital británico por el estadounidense—en estricto sentido, californiano—como arrendatario de la Casa de Moneda de México en 1857. Asimismo, explora el desarrollo empresarial de Juan Temple para explicar la coyuntura política que hizo posible su llegada, y la de sus descendientes, a la administración de la ceca de la capital mexicana.

During the first half of the nineteenth century, the budgetary needs of the Mexican treasury forced the government to resort to borrowing and leasing some of the most important mints in the country. This article examines the political and economic conditions that allowed for the replacement of British capital by United States capital—specifically, Californian—as the lessee of the Mexican National Mint in 1857. It also explores the development of Juan Temple’s entrepreneurship to explain the political circumstances that facilitated his admission, and that of his descendants, into the administration of the National Mint in Mexico City.

Published: December 2019

Autophagy is a highly conserved catabolic process through which defective or otherwise harmful cellular components are targeted for degradation via the lysosomal route. Regulatory pathways, involving post‐translational modifications such as phosphorylation, play a critical role in controlling this tightly orchestrated process. Here, we demonstrate that TBK1 regulates autophagy by phosphorylating autophagy modifiers LC3C and GABARAP‐L2 on surface‐exposed serine residues (LC3C S93 and S96; GABARAP‐L2 S87 and S88). This phosphorylation event impedes their binding to the processing enzyme ATG4 by destabilizing the complex. Phosphorylated LC3C/GABARAP‐L2 cannot be removed from liposomes by ATG4 and are thus protected from ATG4‐mediated premature removal from nascent autophagosomes. This ensures a steady coat of lipidated LC3C/GABARAP‐L2 throughout the early steps in autophagosome formation and aids in maintaining a unidirectional flow of the autophagosome to the lysosome. Taken together, we present a new regulatory mechanism of autophagy, which influences the conjugation and de‐conjugation of LC3C and GABARAP‐L2 to autophagosomes by TBK1‐mediated phosphorylation.
Protest engagement: weak vs strong social ties
Authors: Moskotina Ruslana
Published: December 2019

This article dwells upon the importance of finding methods and ways of studying protest behaviour that can explain its emergence. Protest behaviour is considered as the result of protest engagement. It is assumed that there are social ties between individuals, potential protesters. M. Granovetter proposes to distinguish strong ties and weak ties. Strong ties tend to form closed and cohesive groups but weak ties can be the bridges that match groups and/or individuals. The author of this article conducts a research with applying a method of agent-based modelling. Its aim is to test the Granovetter’s thesis about the strength of weak ties towards protest behaviour. In this research the linear threshold model is used. Our research with applying method of the agent-based modelling includes the computer experiments (simulations) with the social networks. There are generated five networks, three of which contain only strong ties and the rest of the networks contain only weak ties. Simulations with the networks allow us to determine the number of inactive agents that are involved in the protest, the speed of the protest engagement and the effectiveness of overcoming the resistance of inactive agents. It is found that both weak ties and strong ties can determine protest behaviour. Strong ties contribute to a quicker protest engagement. Weak ties can better overcome the resistance of inactive agents. At the same time weak ties slow down the process of the protest engagement and strong ties are generally less effective in overcoming the resistance of inactive agents. Agent-based modelling helps us to conduct the fundamental research. On the one hand we test Granovetter’s thesis about the strength of weak ties towards protest behaviour. On the other hand we cannot draw conclusions about protest behaviour in Ukraine. But we can conduct an empirical sociological study in order to test the results of our research and understand its relevance towards protest behaviour in Ukraine.
Social perception of private owners of the production means in Ukraine
Authors: Rakhmanov Oleksandr
Published: December 2019

The main markers of social perception of private owners by the Ukrainian population are the content of private property and the form of personal involvement of private owners in production. The research objective was to analyse the social perceptions determinants of private owners of enterprises and land. Using the data of a sociological survey conducted by the Institute of Sociology of the NAS of Ukraine in August 2019, private owners’ social perceptions of the production means with different forms of management were analysed: small enterprises, large enterprises, land cultivated by the owner’s family, land cultivated by hired workers. The owners of small enterprises and the owners of land cultivated by their families enjoy greater sympathy among the Ukrainian population than owners of large enterprises and owners of land cultivated by hired workers. However, even in the case of the last two categories of private owners, positive feelings outweigh negative ones. The methods of binary logistic regression used in this research, reveal that the social perceptions of the private owners of the production means are largely consistent with social status, an ability to adapt to a market economy, and relevant value-ideological beliefs. The negative perception of private owners depends on the type of production means. In particular, respondents’ negative feelings about large enterprises owners and landowners who use hired labour are determined by the support of a planned economy and the rejection of liberal values. The impact of an external locus of control of the respondents became decisive in the negative perception of small business owners. Negative feelings about landowners who cultivate the land themselves are evident in respondents with low levels of education. Positive feelings in all cases are conditioned by the respondents’ support of liberal and mixed type of economy, their positive perception of liberal values, adaptability to market conditions, high level of education and wealthy financial situation. Neutral feelings towards private owners of all categories are evident among respondents who are undecided about the type of economy.

Published: December 2019

An adaptation of the national water resources management system in accordance with the requirements of European legislation creates the legislative basis for reforms im- plementation in the field of monitoring and water use. The basin management principle started to be applied, according to which surface and groundwater arrays are the water resources management units. The preliminary groundwater array status assessment (both quantitative and qualitative) is a necessary procedure that enforces the development of appropriate monitoring program and measures elaboration in order to improve groundwater ecological status. This study tested a methodology of groundwater deterioration risk assessment as a tool for previous groundwater array cological status estimation. The research provides an approbation of the methodology in relation to groundwater arrays identified and delineated within Siversky Donets river basin (that covers Kharkiv, Donetsk and Lugansk regions). Surface water and groundwater are affected by significant anthropogenic pressures in form of pollution from point sources of heavy industry facilities. A risk model comprises groundwater vulnerability map and simulated model of anthropogenic pressure magnitude distribution reflecting the impact extent of the main sources of groundwater pollution. Vulnerability map was developed using the tool of input factors weight index estimation. Authors considered the following factors as determining – soils characteristic, aeration zone characteristics, geological environment of groundwater arrays of Cenozoic-Mesozoic group. The pollution load index was calculated. Input data for calculation are concentrations of hazardous substances (metals, semimetals, halogens and nitrates and phenol compounds) measured in groundwater samples during the 2017 monitoring year period. The results of the value interpolation of calculated pollution load index reproduce the focal (point) nature of groundwater pollution and indicates the significant groundwater pollution of Quaternary and Upper Cretaceous, both Carboniferous aquifers and corresponding groundwater arrays. A logical matrix is created on the basis of a combination of pres- sure magnitudes and vulnerability classes. The area of each class of risk is calculated within groundwater arrays with zonal statistic technique. Consequently, each groundwater array is assigned with preliminary estimated risk category. Created model enables to per- form previous groundwater array status assessment. The proposed model expected to be more useful after the data on pollution from diffuse sources obtaining and its validation after the first stage of surveillance monitoring realization.

Natural Sources of Spraying to Preserve Apple Fruit Quality during Post-Harvest
Authors: ACEVEDO-BARRERA Angelica A. , SOTO PARRA Juan M. , YAÑEZ-MUÑOZ Rosa M. , SANCHEZ Esteban , PEREZ-LEAL Ramona
Published: December 2019

One of the great challenges that apple producers face is to substantially improve the quality of fruit, including after harvest. A balanced and timely supply of calcium (Ca) during growth and in the post-harvest stage is considered a technique that could improve shelf life and fruit quality; thus calcium plays a key role during post-harvest, with calcium carbonate and calcium sulphate being an alternative of foliar spraying. The study was carried out on ‘Top Red’ and ‘Golden Delicious’ apple cultivars, in a randomized complete block design with 13 treatments (referring to different commercial presentations of calcium) and 6 repetitions; 8 foliar sprays were applied weekly, from June 22 until harvest; ‘Top Red’ (151 days after full flowering, DDCF) and ‘Golden Delicious’ (145 DDCF) fruit were evaluated in regard with fruit traits (diameter, weight and colour) and maturity (pulp firmness, total soluble solids, titratable acidity and sugar acidity ratio). In ‘Top Red’ cv., calcium carbonate presented the best results, with intermediate to high quality apple fruit, while for cv. ‘Golden Delicious’ the best results were obtained with calcium sulphate, which increased fruits’ diameter, weight, colour and titratable acidity. Even more, of the products evaluated, CaCO3 and CaSO4 had the lowest costs, and can be considered as good alternatives of foliar calcium supplement applied in order to preserve the quality of the apple during post-harvest.

Effect of Sunny and Half-shaded Sites on the Growth of Plants and Anthocyanin Pigments Content in Leaves of Heuchera L. ‘Mysteria’ and ‘Peppermint Spice’ Cultivars
Authors: JANOWSKA Beata , CZUCHAJ Piotr K. , KUBIŚ Jan , RYBUS-ZAJĄC Magdalena , KOKOCIŃSKA Daniela
Published: December 2019

Two cultivars of Heuchera L. - ‘Mysteria’ and ‘Peppermint Spice’ were grown in a collection at a sunny site and a slightly shaded one. The access of sunlight was limited by shade nets, which were stretched on wooden scaffolding over the plants. The dynamics of growth of the plants in the sunny and half-shaded sites was assessed in the growth periods, in two consecutive years. After the second year, the content of anthocyanins in the leaves of different physiological maturity (young, mature and fully mature) was measured. Apart from August, during the whole growth period both cultivars formed more leaves during the first year of cultivation. Both the ‘Mysteria’ and ‘Peppermint Spice’ cultivars formed more leaves at the sunny site. The research showed that the highest content of anthocyanins in the Heuchera ‘Mysteria’ and ‘Peppermint Spice’ cultivars growing at the sunny and half-shaded sites was found in young leaves, whereas the lowest content was noted in fully mature leaves. The highest content of anthocyanins in both Heuchera cultivars was found at the initial growth period, i.e. between May and July, when the light intensity was the greatest, regardless of the place of cultivation. At the end of the growth period, the biosynthesis of anthocyanins decreased significantly. Anthocyanins accumulated in the vacuole are able to play a role as the screening pigments under intensive PAR and UV-B radiation.

Published: December 2019

Investigation on the level and pattern of genetic diversity of 10 natural populations of the endangered species Fraxinus hupehensis using inter-simple sequence repeat (ISSR) markers was crucial for understanding the structure of the population and assessing the best genetic protection strategies. A total of 180 polymorphic bands with the polymorphic rate of 100.00% were amplified by 14 primers. The genetic diversity at population level (Percentage of polymorphic loci, PPL=64.06; Nei’s gene diversity index, h=0.1519; Shannon’s information index, I=0.2434) was lower than that at species level (PPL= 100.00%, h=0.1833, I=0.3041). Analysis of molecular variance (AMOVA) demonstrated the low level of the genetic variation occurred between the populations (16.05%). This also can be corroborated by the gene flow (Nm 2.424) and the coefficient of gene differentiation (Gst=0.1710) among populations. Cluster analysis based on the unweighted pair group method with arithmetic averages (UPGMA) revealed four groups for 10 populations according to Nei’s genetic identity and seven categories for the 196 individuals according to SM values. Furthermore, the endangered mechanism and genetic structure of F. hupehensis were discussed, and appropriate targeted protection measures were proposed based on these findings.

Hyd yn hyn, prin iawn oedd y ffeithiau y llwyddwyd i'w darganfod am gefndir a floruit Gruffydd Robert cyn 1558, pan benodwyd ef yn Archddiacon Môn. Fodd bynnag, fe gadarnheir gan gofnodion a ddiogelwyd yn archifdai Milan mai gŵr o sir Gaernarfon ydoedd; fe'i ganwyd
c. 1527 yn fab i ryw Robert a boneddiges o'r enw Catrin ferch Gruffudd, ac y mae tystiolaeth o blaid credu ei fod yn nai i Forys Clynnog, darpar esgob Bangor. Ordeiniwyd ef i'r offeiriadaeth yn Rhufain yn 1563; erbyn 1565 yr oedd ym Milan, lle cyhoeddwyd y Dosparth Byrr, sef
rhan gyntaf y gramadeg Cymraeg a luniodd. Bu Gruffydd Robert yng ngwasanaeth y Cardinal Carlo Borromeo a'i olynwyr esgobol weddill ei oes. Cofnodwyd yn Libro dei morti y ddinas iddo farw 15 Mai 1598.
Sport, Class and Identity at Swansea, 1870–1914
Authors: Rees Barry
Published: December 2019

This article discusses the growth of rugby as the most popular pastime in Swansea for most of the period 1870–1914. It examines how the game shaped an inclusive civic identity from the 1890s and how this was layered alongside other identities. It also examines how social class
and gender were negotiated during the game's rise. Swansea's middle class stamped its authority on local government and voluntary institutions and the town's rugby club was among the foremost of these institutions by the end of the 1870s. It is argued that sport offered a unique opportunity
for new civic alliances.

La familia tiene una influencia determinante en el desarrollo de habilidades socioemocionales, como la Inteligencia Emocional (IE), en  niños y adolescentes. Sin embargo, actualmente existen pocos estudios empíricos que ayuden a profundizar en la temática. Por lo anterior, la presente investigación tuvo como objetivo determinar las correlaciones existentes entre la IE y las Practicas Parentales percibidas por estudiantes de 2º año de la Secundaria Técnica Número 96 de la ciudad de Puebla. Para lograr dicho propósito se aplicó el TMMS-24 junto con la Escala de Prácticas Parentales para Adolescentes de Andrade Palos y Betancourt Ocampo (2008) a 196 jóvenes entre los 13 y 15 años de edad. Posteriormente, al analizar los resultados de ambos instrumentos, se encontró que las prácticas parentales de autonomía, comunicación y control conductual se correlacionan positivamente con la IE en tanto que las prácticas parentales de control psicológico se correlacionan negativamente con la IE.

El ejercicio de la paternidad se haya condicionado por los rasgos de personalidad de los progenitores (Desjardins, Zelenski Coplan, 2008; Lomanowska, Boívin, Hertzman Fleming, 2017). Las primeras huellas en la literatura científica que describen esta realidad podemos encontrarlas en el trabajo de Belsky (1984). Alude a la influencia de las características personales de los progenitores en los estilos educativos (Prinzie, Stams, Dekovic, Reijntjes Belsky, 2009). Vondra, Bittman y Belsky (2008) relacionan personalidad y paternidad por medio de tres dimensiones: diferenciación psicológica parental, afecto negativo y trastorno psicológico. Defienden que la habilidad para la crianza se verá modulada por la personalidad y ajuste exhibido por los progenitores. De este modo, ciertos rasgos de personalidad, tales como la psicopatía parental o emocional negativa, condicionan la apreciación de problemas conductuales en la infancia (Angelini, Klijs, Smidt Mierau, 2016; Desjardins, Zlenski Goplan, 2008; Lomanowka, et al., 2017; Oliver, Wright Coffman, 2009). De hecho, se ha encontrado que las características personales maternas predicen comportamientos infantiles. El bienestar psicológico de las madres correlaciona con los problemas en el desarrollo de sus hijos/as (Camsranesi, 2016; Nikolaev, Baranova Petunova, 2016). En esta investigación hemos analizado las relaciones existentes entre los rasgos de personalidad parental en el desarrollo del apego y la aparición de problemas de conducta. Para ello hemos utilizado distintas pruebas psicométricas objetivas validadas y comercializadas. A la vez, como se indica en la literatura, para la medición del apego en las edades establecidas en la investigación, hemos utilizado una prueba proyectiva. Los resultados obtenidos en el centro educativo evaluado nos ratifican y verifican una muy alta correlación en el triángulo tipo personalidad parental, configuración del apego y problemas de conducta.
Maternal and paternal psychopathological risk in children with non-organic failure to thrive
Authors: Cerniglia Luca , Cimino Silvia
Published: December 2019

Investigaciones en el campo de la psicopatología del desarrollo han subrayado que la psicopatología materna es un factor de riesgo crucial para el desarrollo y mantenimiento de los trastornos alimentarios en los niños. Sin embargo, la literatura científica que ha estudiado los resultados de las dificultades emocionales maternas (por ejemplo, los trastornos alimentarios maternos) sobre el funcionamiento psicológico del niño no ha tenido en cuenta adecuadamente el papel del padre como riesgo potencial o factor de protección. El presente estudio longitudinal tuvo como objetivo elaborar sobre el impacto del funcionamiento psicológico materno en la adaptación del niño entre la primera y la segunda infancia. La muestra está compuesta por N = 60 padres con hijos que han seguido un protocolo de investigación longitudinal y han sido reclutados a través de guarderías, escuelas primarias y clínicas de atención ambulatoria. En tres momentos de evaluación (T1, T2, T3), tanto el Grupo clínico (CG) como el Grupo no clínico (NCG) han sido evaluados a través de: SCID-I (diagnóstico psiquiátrico parental); SCL-90-R (riesgo psicopatológico de los padres); EAT-40 (alimentación desordenada de los padres); CBCL (funcionamiento emocional-conductual de los niños). Nuestra investigación ha confirmado que los niños con dificultades severas en el área de alimentación tienden a tener madres que muestran problemas en el mismo campo. De hecho, el diagnóstico de trastorno alimentario en las madres parece predecir el fracaso para prosperar en los niños solo en el Tiempo 1, mientras que se asocia con un funcionamiento psicológico emocional desadaptativo tanto en la primera como en la segunda infancia. Los niños con trastornos alimentarios también parecen tener más probabilidades de tener padres con perfiles psicológicos problemáticamente estables.

Sentirse profesores eficaces significa creer en las propias capacidades de influir en la prestación de los estudiantes y las modalidades de aprendizaje de los alumnos, incluso los más difíciles o desganados (Guskey y Passaro, 1994). La autoeficacia aumenta la motivación, la cuantía del compromiso empleado, el tiempo dedicado y, en el ámbito laboral, mejora la satisfacción laboral. En el presente trabajo, se ha querido investigar la relación entre la autoeficacia y la formación continua de los profesores, teniendo como objetivo general demostrar que la participación en cursos de actualización, diplomas de perfeccionamiento o master contribuya a aumentar el sentido de eficacia de los profesores. Además, se perseguirán los objetivos de evaluar lo que afecta a la precariedad en el sentido de autoeficacia y analizar las variables que influyen en la autoeficacia percibida por los profesores.A la investigación participaron 225 profesores italianos, que respondieron a través de una suministración on line, a un protocolo de investigación, que comprenda las siguientes escalas de medida: Escala de eficacia personal en el ámbito escolar (Borgogni, Petitta, Steca, 2001), escala de eficacia colectiva percibida en el ámbito escolar (Borgogni, Petitta, Steca, 2001), escala de Self-Efficacy general de Schwarzer, en su adaptación italiana de Lucio Sibilia, Ralf Schwarzer Matthias Jerusalem (1995), cuestionario sobre la satisfacción laboral de Weiss et al. (1967), adaptado y validado en italiano por Di Nuovo y Alba (1990), Survey of Perceived Organizational Support de Eisenberg et al. (1986), adaptado y validado en italiano por Battistelli y marianos en 2011, escala del Compromiso Organizacional y de la implicación en el trabajo de Barbaranelli y Fida (Barbaranelli, Fida, Paciello, Di Giunta, Caprara 2008). Entre los resultados se desprende que los profesores que han frecuentado más cursos de formación y master en los últimos tres años obtienen puntuaciones significativamente más altas en la escala de Autoeficacia escolar personal respeto a los profesores que no lo han frecuentado; además, los profesores titulares resultan tener una eficacia escolar personal significativamente más alta con respecto a los profesores temporales. Además, del análisis de las regresiones lineales se desprende que las variables que predicen la eficacia escolar personal son la eficacia escolar colectiva, la selfefficacy general y su implicación en el trabajo. Dado que la eficacia personal está influida también por la eficacia colectiva, en conclusión, parece necesario dirigir tipos de intervención a la escuela centradas sobre las variables de tipo colectivoy organizativo, que mejoren el sentido de pertenencia, la identidad organizativa, la comunicacióninterna y externa.
