Published: August 2017

Background—
We sought to compare maximal left ventricular (LV) wall thickness (WT) measurements as obtained by routine clinical practice between echocardiography and cardiac magnetic resonance (CMR) and document causes of discrepancy.

Methods and Results—
One-hundred and ninety-five patients with hypertrophic cardiomyopathy (median age, 52.8±15.1 years) who underwent echocardiography and CMR imaging within 6 months (median, 41 days; interquartile range, 16–97 days) were included. LVWT was assessed in parasternal long and short axis by 2-dimensional echocardiography and in short axis by CMR. By Bland–Altman plot, mean maximal LVWT difference between echocardiography and CMR was 0.5 mm (95% confidence interval, −6.9, 7.8) with equal distribution of discrepancy along the full range of LVWT. Ninety-seven patients (49.7%) were identified to have intermodal measurement discrepancies ≥10%. In 7 patients (7.2%), reported measurement by CMR was inaccurate because of interpretation error. In 90 patients (92.8%), echocardiography underestimated (n=32; 33.0%) or overestimated (n=58; 59.8%) maximal LVWT. Underestimation was because of focal LV hypertrophy (n=10; 10.3%) or poor acoustic windows (n=22; 22.7%) while overestimation resulted from inclusion of right ventricular myocardium (n=37; 38.1%), LV trabeculations (n=5; 5.2%), papillary muscle (n=3; 3.1%), and apical-septal bundle (n=1; 1.0%), as well as imaging plane obliquity (n=7; 12.5%). In 31 (15.9%) patients, measurement discrepancy occurred at diagnostic or prognostic cut-offs.

Conclusions—
Although maximal LVWT by echocardiography in general measured similar to CMR, discordance because of limitations in echocardiography technique was present in a significant subset of patients. As measurement of LVWT impacts diagnosis and sudden death management, CMR should be considered as part of routine evaluation of all patients with hypertrophic cardiomyopathy.
The influence of amniotic membrane extracts on cell growth depends on the part of membrane and childbirth mode selected: a proof-of-concept study
Authors: Litwiniuk M. , Radowicka M. , Krejner A. , Grzela T. 
Published: August 2017

Objective: The amniotic membrane (AM) is a rich source of biologically active factors, important for wound healing and is widely used in various clinical applications, including tissue engineering, reconstructive surgery and wound management. The aim of the present proof-of-concept study was to assess the influence of amniotic membrane extracts on in vitro proliferation of main cells involved in tissue regeneration. The assessment was done in regards to the content of selected biologically active factors in amniotic membrane extracts. Method: The quantitative analysis of EGF, TGF-β and TIMP-1 in tested samples was assayed by enzyme-linked immunosorbent assay (ELISA) tests. The influence of amniotic membrane extracts on proliferation of keratinocytes (HaCaT), fibroblasts (Wi-38) and endothelial cell lines (HECa-10) was assessed using a colorimetric tetrazolium salt reduction assay. Results: In all of the amnion samples high amounts of EGF, TGF-β and TIMP-1 were detected. However, the content of these factors varied between placental and cervical portions of the same membrane. Moreover, various concentrations of biologically active factors between physiological at-term delivery and caesarean section-derived membranes were also observed. All of the assessed amnion extracts stimulated proliferation of HaCaT and Wi-38 cells, although samples prepared from caesarean section-derived cervical portion of amniotic membrane stimulated more proliferation of keratinocytes than of fibroblasts. In contrast to HaCaT and Wi-38 cells, proliferation of HECa-10 cell line was inhibited by all tested extracts. Conclusion: The results of our proof-of-concept study confirm that biological dressings prepared from amniotic membrane, especially its placental portion, since they stimulated both fibroblasts and keratinocytes, may provide relevant support for wound healing. On the other hand, dressings prepared from caesarean section-derived cervical portion of amniotic membrane, since they stimulate mainly epidermal cells, may be suitable for some specific applications, where more selective action is required, such as in ocular surgery. However, verification of this observation requires further studies.
Plantations versus the people: Explaining the diversity of land policies within the tropical British Empire
Authors: Byerlee Derek 
Published: August 2017

Abstract
Property rights regimes governing the expansion of agricultural commodity exports in the tropics have varied widely between and within colonial empires. This article illustrates this diversity within the British Empire from about 1850 to 1920. In British West Africa, indigenous customary rights were recognized and land concessions to plantations excluded. By contrast, colonial governments alienated large land tracts for plantations in Malaya, the Indian Hills and Ceylon that often conflicted with indigenous rights and shifting farming systems in upland forested areas. These differences among colonial policies on land and forest rights in turn led to quite different agrarian structures and strongly influenced the location of export production – differences that have persisted until today. The article explores a range of explanations for policy divergence with respect to land rights, including the initial conditions of population density and pre-existing industries, strategic concerns of the metropolitan power, growing civil society agitation on human rights in Africa, the role of individual champions of human rights and shifting paradigms within the empire with respect to the role of plantations.
The land question in early twentieth-century Portuguese legal colonial thought
Authors: Direito Bárbara 
Published: August 2017

Abstract
Part of a broader effort to bring the land question to the fore of scholarship about colonial Mozambique, this article looks at how legal colonial thought about land and property, part of the growing body of knowledge about topics of interest to the colonies, developed among Portuguese colonialists in the early twentieth century, especially with regard to African access to land. Different contributions to this thought will be analysed to enquire the role the land question played in the Portuguese colonial project in Africa. The main theories and debates about the land question held in Portugal will then be analysed alongside theories and debates about this same topic within an increasingly internationalized field of colonial thought, in which Portuguese colonialists also took part.
The Treaty of Versailles, the League of Nations and Portuguese overseas policy (1910–26)
Authors: Mendes Nuno Canas 
Published: August 2017

Abstract
The main goal of this article is to present the challenges for Portuguese colonial policy during the First Republic (1910–26), focusing on the international pressures against the survival of the Portuguese Empire. The article is divided into three parts: in the first we outline the state of the art regarding the questions to be raised. This is followed by an analysis of Portuguese colonial policy in the post-Versailles international context, particularly Afonso Costa’s negotiations for war reparations. In the third part, we examine particular aspects of the relationship between Portugal and the League of Nations in relation to colonial questions: namely, forced labour and the illicit trafficking of opium.
Evaluation and participation: Identifying different school organization profiles in Portuguese public schools
Authors: Veloso Luísa , Craveiro Daniela 
Published: August 2017

Abstract
The article discusses some of the major changes in Portuguese schools, due to both the external evaluation process set up in 2008 and the new school management model. The results discussed here demonstrate how the external evaluation process in Portugal highlights the importance of schools as organizations and the focus on community involvement in school management. A multivariate analysis based on a set of variables enabled us to define three school organization profiles (innovative, traditional and diffuse) using two points of reference: the type of curriculum offered and the relationship with the school community. The article consolidates an analysis based on mixed-method research, enhancing the analysis of qualitative information, how qualitative information can be turned into quantified variables, and how data reducing provides support for quantitative and qualitative data analysis.

Słowniki Bartłomieja z Bydgoszczy (1532 i 1544). Stan badań i perspektywy badawcze
Authors: Jankowiak Lucyna Agnieszka 
Published: August 2017

The purpose of this article is to recall the 16th century Latin-Polish dictionaries by Bartholomew of Bydgoszcz. The article describes the figure of the monk, the history of his works as well as their structure and contents. The interest in the lexicons grew in the 70s of the 20th century when a manuscript dated 1532 (considered to be lost after the second world war) was found and a dictionary dated 1544 was unexpectedly discovered. A decision was made then to (jointly) publish both lexicons in the reversed version (Polish-Latin). This project still has not been completed which certainly has had its effect on the researchers’ weakening interest in the dictionaries and a small number of publications. Therefore the article presents possibilities of the analysis of the Polish and Latin lexical material.
Znaczenie i funkcja motywu klonu w warmińsko-mazurskich pieśniach ludowych
Authors: Lechocka Ewelina 
Published: August 2017

This article is an analysis of maple motives, which occurred in collection of Warmian and Masurian folk songs elaborated in XIX and XX century. The purpose of this study was to define meaning and function botanic vocabulary mentioned in folkloristic texts and to compare poetic representation of maple motif with its role in every-day-life and culture of Warmia and Masuria’s inhabitants. As it was deducted from maintained analysis, the folk output and botanic themes are a valuable source of information about identity of rural population from Warmia and Masuria territories. Utilization of maple motif in folksongs is characteristic for its strong resemblance to empiric reality, in which the plant plays a great role in every-day-life and in immaterial culture.
Przywódca populistyczny i jego językowy obraz w aspekcie retoryki dominacji na podstawie wypowiedzi Pawła Kukiza. Perspektywa politologiczna i lingwistyczna
Authors: Kołodziejczak Małgorzata , Wrześniewska-Pietrzak Marta 
Published: August 2017

The aim of this paper is characterizing one of the main populistic categories – the populistic leader. The problem was described from politological and linguistic point of view. The analyzed texts are Paweł Kukiz’ statements presented in the sessions of the Sejm (a lower chamber of the Polish parliament) and his Facebook posts. This paper presents the most important features which build the linguistic image of populistic leader. The authors claim that the image of populistic leader created in Paweł Kukiz’ texts is strictly combined with the dominance and its linguistic ways of expression, regarding the opposites to the people (citizens) and elites (political parties etc.). The cohesion of the described image of the populistic leader is created with the opposite we – they, which is ambiguous in the analyzed texts and enables Paweł Kukiz to construct different roles he plays in politics.

The aim of the present paper is the analysis of old nicknames which relate to the way in which our ancestors communicated. The subject of the analysis are proprial items, which were formed in order to indicate if the speakers were telling the truth, or whether they were gossiping, or saying too much, as well as items which evaluated a person because of articulatory features. The present paper is also an attempt to propose research into axiologically marked appelative anthroponyms within the methodology of cultural linguistics, complemented with biological contexts, especially research from the field of evolutionary psychology and biological anthropology.
Graficzne i fonetyczne warianty techniczne w polskiej edycji Żywotów filozofów Mikuláša Konáča (F. Ungler, Kraków 1535)
Authors: Osiewicz Marek 
Published: August 2017

The article attempts the technical determination of the graphic and phonetic variance acknowledged in the Polish edition of the Żywoty filozofów by Mikuláš Konáč. The method used was to analyze the distribution of oppositional graphic forms. It has been determined that the technical nature of the print is 9 variants: 4 graphic variants („j” = /j/ in position before consonant, „j” = /j/ in the voice-over position, „u” = /v/ i /v/ in the midpoint position, „th” = /t/) and 5 phonetic variants (miesce, miejsce, miejstce; wszystko; wieliki); among them are both regressive and progressive forms. The analysis also shows that, using the disclosed technical variants, zecer manipulated the graphical content of the lines in both possible ways: narrowing or widening.

Authors: Freudenthaler Gerhard , Meurer Thomas 
Published: August 2017

Zusammenfassung
Es wird eine 2-Freiheitsgraderegelung (2-FHG) für die Formationsregelung eines Multi-Agentensystems in gewünschte Profile
entwickelt. Dabei wird ein Kontinuumsmodell in Form einer modifizierten viskosen Burgersgleichung herangezogen. Für diese
Form der Agentendynamik kann eine flachheitsbasierte Vorsteuerung mit einer Backstepping-basierten Randwertregelung
kombiniert werden, welche das Folgefehlersystem stabilisiert. Es wird gezeigt, dass die Einführung eines
verteilt-parametrischen Exosystems die translatorische Verschiebung der Formation ermöglicht. Die Übertragung der
Regelungsstrategie von einem unendlich-dimensionalen, kontinuierlichen zu einem endlich-dimensionalen, diskreten
Multi-Agentensystem erfolgt durch geeignete Diskretisierung, welche die notwendige Kommunikationstopologie einprägt. Die
Ergebnisse werden in Simulationen evaluiert.

Abstract
García-Vaquero, MP, Ruiz-Pérez, I, Barbado, D, and Vera-Garcia, FJ. Electromyographic and kinematic analysis of the flexion-rotation trunk test. J Strength Cond Res 34(12): 3386–3394, 2020—Although most trunk endurance field protocols are performed in the sagittal or frontal planes, the flexion-rotation trunk (FRT) test combines trunk flexion with rotation, which may be relevant to rotation-related sports. The aim of this study was to describe the trunk and hip muscle activation and fatigue and the range of hip flexion of this test. Twenty-seven physically active males and females performed the FRT test after a period of practice. Electromyographic (EMG) signals were bilaterally collected from the rectus abdominis (RA), internal oblique (IO), and rectus femoris (RF), and hip flexion amplitude was measured using a biaxial electrogoniometer. Because the fast Fourier transform algorithm requires stationary EMG signals, subjects performed a 6-second isometric trunk flexion-rotation repetition just before and just after the test execution (preexecution and postexecution repetitions, respectively). Rectus abdominis showed the highest mean activation levels (approximately 30% maximal voluntary isometric contractions [MVC]) in the preexecution repetition, followed by IO (approximately 20% MVC). Also, the mean power frequency (MPF) significantly decreased from the pre-execution to the postexecution repetition for RA and IO, which shows abdominal muscle fatigue. Although each trunk flexion-rotation repetition involved an average 8–14° hip flexion, the RF activation was lower than 10% MVC, and no significant MPF reduction (i.e., no muscle fatigue) was observed for this muscle. In addition, significant negative correlations were found between the FRT test scores and the normalized EMG amplitudes of RF. Based on these results, the FRT test seems a valid field protocol to assess abdominal muscle endurance in trunk flexion-rotation exertions.

En plena vorágine revolucionaria, México fue el escenario de animados debates de opinión que se centraban en las implicaciones directas que la Primera Guerra Mundial pudiera tener sobre los derroteros de la nación. Si bien su estudio ha sido en gran parte ignorado, su análisis es crucial para la comprensión del pensamiento mexicano durante y después del conflicto. Tras un balance historiográfico, este trabajo define el escenario de dichos debates de opinión, identifica su punto más álgido durante el año 1917 y analiza su evolución en tres de sus principales foros: la prensa, el Poder Legislativo y las asambleas estudiantiles.
While in the thick of a revolutionary maelstrom, Mexico was the setting for animated debates centered on the direct implications that World War I might have on the nation’s future. Although its study has been largely ignored, analysis of the Great War is crucial for understanding Mexican thought during and after the conflict. In addition to offering a historiographical assessment, this work elaborates the scenes of said debates, identifies their most decisive moment during the year 1917, and analyzes their evolution in three of their principle forums: the press, the Legislative Branch, and student assemblies.
Variation in Recombination Rate and Its Genetic Determinism in Sheep Populations

Abstract
Recombination is a complex biological process that results from a cascade of multiple events during meiosis. Understanding the genetic determinism of recombination can help to understand if and how these events are interacting. To tackle this question, we studied the patterns of recombination in sheep, using multiple approaches and data sets. We constructed male recombination maps in a dairy breed from the south of France (the Lacaune breed) at a fine scale by combining meiotic recombination rates from a large pedigree genotyped with a 50K SNP array and historical recombination rates from a sample of unrelated individuals genotyped with a 600K SNP array. This analysis revealed recombination patterns in sheep similar to other mammals but also genome regions that have likely been affected by directional and diversifying selection. We estimated the average recombination rate of Lacaune sheep at 1.5 cM/Mb, identified ∼50,000 crossover hotspots on the genome, and found a high correlation between historical and meiotic recombination rate estimates. A genome-wide association study revealed two major loci affecting interindividual variation in recombination rate in Lacaune, including the RNF212 and HEI10 genes and possibly two other loci of smaller effects including the KCNJ15 and FSHR genes. The comparison of these new results to those obtained previously in a distantly related population of domestic sheep (the Soay) revealed that Soay and Lacaune males have a very similar distribution of recombination along the genome. The two data sets were thus combined to create more precise male meiotic recombination maps in Sheep. However, despite their similar recombination maps, Soay and Lacaune males were found to exhibit different heritabilities and QTL effects for interindividual variation in genome-wide recombination rates. This highlights the robustness of recombination patterns to underlying variation in their genetic determinism.
