Authors: Kumar Vikas , Varshney R. K. , Kumar Sunil
Published: January 2020

We report a broadband polarization splitter based on polyethylene photonic crystal fiber with microstructured dual refractive index gradient cores. These dual cores consist of a properly optimized arrangement of air holes such that for individual fibers

-polarized modes. We have shown that by proper optimization of gradience created in the arrangement of air holes, efficient polarization splitting can be achieved for a broad range of terahertz frequencies. Device length and extinction ratio have been calculated numerically for the proposed configuration. Device length of

Published: January 2020

We present an interferometric method to analyze transparent samples using complex fringes generated by a parallel phase shifting radial shear interferometer using two coupled interferometers. Parallel interferograms are generated using two interferometers: the first one generates the polarized base pattern, and the second system is used to generate parallel interferograms allowing the adjustment of the

positions of the parallel interferograms. To obtain the optical phase map, parallel phase shift is generated by collocating polarizing filters at the output of the system; the polarizers are placed at arbitrary angles since they do not require adjustment because of the phase-recovery algorithm. The optical phase was processed using a two-step algorithm based on a modified Gram–Schmidt orthogonalization method. Such an algorithm has the advantage of not being iterative and is robust to amplitude modulation. The proposed method reduces the number of captures needed in phase-shifting interferometry. We applied the developed system to examine static and dynamics phase objects.
Beam wander in wireless optical communications between misaligned transceivers in oceanic turbulence
Authors: Cui Zongmin , Yue Peng , Yi Xiang , Li Jing
Published: January 2020

In this paper, we investigate the beam wander in oceanic turbulence taking into account the misaligned displacements caused by slight changes in the position and attitude of the underwater platform. First, we derive the longitudinal distance and radial distance or the misaligned displacements according to the relationship between the misaligned transceivers. Then, we formulate the beam wander variance of a Gaussian beam propagating through oceanic turbulence. Finally, we obtain the beam wander variance in underwater wireless optical communications between the misaligned transceivers according to longitudinal distance. In addition, we express the mean pointing error displacements.
C-cavity fiber laser employing a chirped fiber Bragg grating for electrically gated wavelength tuning
Authors: Lindberg Robert , Laurell Fredrik , Fröjdh Krister , Margulis Walter
Published: January 2020

We present a novel C-cavity concept for tunable lasers. The laser is based on a semiconductor optical amplifier (SOA), serving both as a gain medium as well as a modulator, and a chirped fiber Bragg grating (C-FBG) which acts as the end mirrors on both cavity ends. Driving the SOA with a pulse pair with variable delay enables wavelength tuning by targeting different regions in the C-FBG with the circulating pulse. The cavity design allows for wide tuning while maintaining a constant repetition rate, we show a tuning range of 35 nm -limited by the C-FBG’s reflection bandwidth. Time-multiplexed operation with four different wavelengths is also demonstrated. Furthermore, the laser performance and dynamics under different operating conditions are analyzed and discussed.

By using this detector, we demonstrated passive terahertz imaging of room-temperature objects with signal-to-noise ratio up to 13 dB. Further improvement in the sensitivity may allow passive terahertz imaging using AlGaN/GaN-HEMT at room temperature.

Authors: Jenne Michael , Flamm Daniel , Chen Keyou , Schäfer Marcel , Kumkar Malte , Nolte Stefan
Published: January 2020

The modification of transparent materials is enabled by focused ultrashort laser pulses. Single pass processing up to several millimeters can be achieved by the usage of elongated beam profiles. We studied the mechanical separability in dependence of the material thickness. As simulations show, asymmetric beam profiles can cause modifications with preferential direction reducing the necessary breaking force. Pump-probe microscopy is implemented to examine the laser-matter-interaction. We present a measured 3D-reconstruction of the transient interaction inside the material and elucidate the desired crack formation. We demonstrate beam shaping concepts to create a new, efficient and robust class of Bessel-like beams, which can be used to achieve a preferred crack direction. We verify the concept by modification and separation of silicate glasses.

Authors: Derbakova Alīna , Zolovs Maksims , Keidāne Dace , Šteingolde Žanete
Published: January 2020

Aim: The research aimed to test the association between the level of immunoglobulin G (IgG) in bovine colostrum and calf blood serum and to evaluate its relation to Cryptosporidium spp. invasion in calves. Materials and Methods: Fresh colostrum and fecal specimens from cows (n=114) as well as blood and fecal specimens from newborn calves (n=114) were collected in the dairy cattle farm. Investigated calves were separated from their mothers directly after birth and received 2 L of colostrum in two separate feedings within the first 24 h. Blood samples were taken from calves at the age of 2 days. Coprological samples were taken from calves at the age of 1, 10, and 15 days. Both colostrum and fecal samples from cows were taken on the 1st day after calf birth. Rectal fecal samples were collected separately from each calf and cow into plastic bags. The collected calf serum samples and bovine colostrum samples were tested for bovine IgG by competitive enzyme-linked immunosorbent assay kit bovine Ig. To record oocysts of Cryptosporidium spp. in feces, the flotation method was used. Binomial logistic regression was performed to ascertain the effects of IgG in bovine colostrum and calf blood serum on the likelihood of Cryptosporidium spp. infection in calves. Results: The concentration of IgG in bovine colostrum was higher (70.7±26.6 g/L, mean±standard deviation) than that in calf blood serum (13.2±6.1 g/L); the statistically significant difference was 57.4 g/L (95% confidence interval, 52.4-62.4), t (124.872)=22.536, p<0.001. Mann–Whitney's U-test showed a significant difference between samples collected on days 10 and 15 of the experiment (U=1944, z=2.330, p=0.020). The higher number of oocysts in calf feces was recorded on day 15 (median=6.5) compared to day 10 (median=4). The prevalence of calf infection from days 10 to 15 increased from 26.3 to 45.6% and was at least 3 times higher than in cows. A statistically significant positive correlation was recorded between IgG concentration of cow colostrum and calf blood serum (r (114)=0.414, p=0.001), whereas a correlation between the concentration of IgG and the intensity of Cryptosporidium spp. infection was not recorded (p>0.05). The logistic regression model was not statistically significant (χ2(2)=0.013, p=0.99 (10 days) and χ2(2)=0.100, p=0.95 (15 days)). Conclusion: Mother passive transfer of immunity to the offspring through colostrum does not influence the susceptibility of calves to Cryptosporidium infestation.

Informação contábil divulgada pode implicar na alocação de recursos no mercado, uma vez que os usuários utilizam essas informações no processo de tomada de decisão. Logo é necessário que tais informações sejam apresentadas com qualidade, para mais bem embasar os processos de decisão. Sendo assim, pesquisas que analisam qualidade da informação contábil tende a serem relevantes para o funciomanento desse mercado. Nesse contexto, o objetivo desse estudo foi analisar a relação entre as características qualitativas da informação contábil e o atraso na entrega das demonstrações financeiras padronizadas (DFPs), aspecto ainda não observado pela literatura nacional e internacional. Para isso, se observou as empresas brasileiras de capital aberto, no período trimestral de 2010 a 2017, via regressão múltipla com dados dispostos em painel, analisando as seguintes características qualitativas observadas: i) conservadorismo, via modelos de Basu (1997) e Ball e Shivakumar (2005); ii) persistência, considerando o modelo de Dechow e Scharnd (2004); iii) relevância, por meio dos modelos de Ohlson (1995) e Easton (1999); iv) tempestividade, via modelo de Lopes e Walker (2008). Os resultados indicaram que a informação de empresas com maior atraso na entrega das DFPs se apresentaram menos conservadora, menos relevante, menos tempestiva e menos persistente. Portanto, o estudo sinaliza aos usuários da informação contábil que maior atraso na entrega das DFPs indica que a informação contábil das empresas não apresenta as características qualitativas esperadas, aspecto que pode auxiliá-los em suas decisões de investimento.
EFEITOS DE REDES E ATUAÇÃO DE FORNECEDORES NA ADOÇÃO DE NOVAS PRÁTICAS CONTÁBEIS POR MUNICÍPIOS DISTANTES
Authors: De Aquino André Carlos Busanelli , Neves Fabrício Ramos
Published: January 2020

O artigo discute a difusão de mudanças compulsórias na gestão financeira de municípios em regiões geográficas isoladas, e apresenta os canais de transmissão preponderantes. A posição que as prefeituras ocupam na rede de municípios importa. A partir da abordagem institucional para redes sociais, a pesquisa usou o caso da adoção compulsória de um novo plano de contas contábeis pelos governos locais. Especificamente o estudo observou como a mensagem sobre a adoção compulsória chegou e foi operacionalizada em um cluster de 10 prefeituras no interior da Bahia. Foram realizadas entrevistas semiestruturadas com contadores, secretários de finanças e fornecedores de softwares de contabilidade da região. As evidências indicam que assessorias terceirizadas foram os principais canais de difusão e de operacionalização da nova prática. Ao terceirizarem a contabilidade, as prefeituras assumiram uma postura passiva, com um entendimento limitado da reforma. A configuração da rede poderia potencialmente estar impedindo a circulação ampla da mensagem sobre a reforma ou a distorcendo, reduzindo assim o engajamento de prefeituras no processo de mudança.

Recently the Government of Indonesia makes a program of Low Cost Green Car (LCGC). The purpose of the program is to support the independence LCGC four-wheeled vehicles industry in order to anticipate the trend of increased demand for energy-efficient motor vehicles and reasonably priced. LCGC program is polemical prolonged. Protests came from all circles. Such as Local Officials, to the Economist. Because the program is properly designed like a cheap car city so that it’s bought by urban communities only According to The Ministry of Industry Article 1 (e) that the Green Car is set up with the price of Rp. 95,000,000.00 (ninety five million). In this case, the government intervened by way Ceiling Price although this intervention thresholds given in the event of structural changes in Indonesia's economic fundamentals, but the policy of intervention was assessed inconsistently. Because the car LCGC-called "earmarked" for the people of the lower middle class but are prohibited from using subsidized fuel. With some reason LCGC issuance of policies by the Government, there are some points that are contradicted by the transport and economic conditions in Indonesia. LCGC policy is certainly contrary to the spirit of alleviating transport problems especially congestion that was hit by the crisis. With the tax-free policy by the government, then the purchasing of the low-cost car will be higher. This is in accordance with the law of demand. The impact is congestion will worsen, especially in the knots of Indonesia's major cities. That means it will grow, the use of fuel and air pollution.

Menyambut kelahiran bayi merupakan kegiatan yang dilakukan sebagai wujud syukur kepada Allah SWT. Diantara ritual yang dilakukan adalah mengumandangkan azan pada telinga kanan dan ikamah pada telinga kiri jabang bayi. Dasar ritual tersebut adalah hadis Muhammad SAW riwayat Abū Dāwūd, at-Tirmῑżi dan Ahmad yang bersumber dari Ibn Abi Rafi’.Tuntunan lain adalah dengan mengistiazahi bayi atau meminta perlindungan kepada Allah Swt untuk keselamatan si bayi, berlandaskan Q.S. Ali Imrān (3) ayat 36 dan hadis nabi yang bersumber dari Abū Hurairah danIbnu ‘Abbās yang diriwayatkan oleh Imām Bukhāri. Ada nuansa keberbedaan di balik kedua tuntunan tersebut, meski sama-sama bersumber dari hadis nabi, maka pembahasan dalam tulisan ini akan menelaah keduanya baik dari sisi Rijal Sanad dan sisi hukumnya. Penelaahan sisi Rijal Sanad dengan menggunakan ‘Ilmu al-Jarḥ wa at-Ta’dῑl sedangkan aspek hukumnya akan didekati dengan menggunakan teori Ta’āruḍ al-Adillāh, disebabkan munculnya keberbedaan diantara keduanya.

Published: January 2020

This article discusses how Japanese people use traditional herbs in Japanese cuisine. Traditional spices or choumiryou which are the focus of research are limited to basic spices consisting of miso, shoyu, and dashi produced from konbu and katsuobushi. Data is collected through documentation of articles and books relating to traditional Japanese spices. The purpose of writing is to find out the type and method of making choumiryo that characterizes Japanese cuisine, as well as how the basic ingredients are used in a dish. The method used is descriptive qualitative to get a complete type and process of making the basic seasoning. From the analysis results it is known that the basic seasoning in Japanese cuisine is not derived from spices as used in Southeast Asian cuisine. Most of Choumiryo comes from the fermentation process of soybeans, beans, wheat or rice, and comes from fish. The manufacturing process is also complex and takes months. Through this process, a delicious taste is produced as well as a natural food preservative.

A review of literature reveals serious problems in the validity and reliability of the measurement tools used in simulation technology acceptance studies conducted in the context of various technology acceptance models. To address this gap in literature, this study proposes a measurement tool that will allow a valid and reliable measurement of students’ acceptance levels. The study was conducted in the 2017–2018 academic year and involved a group of 409 health sciences students. Exploratory factor analysis (EFA) was conducted to examine the construct validity of the conclusions based on gathered measurements. At the end of the EFA, a construct with a single factor and 24 items which explained 54.87 percent of the total variance was obtained. Based on the findings of the research, it was concluded that simulation acceptance scale produced from the EFA could be used for valid and reliable measurements regarding the general acceptance of simulation technologies by the health sciences students.

The need for value-oriented upbringing is obvious and necessary, though difficult in the world full of contrasts, conflicts and plurality of worldviews. Upbringing to values is aimed at preparing children and young people to individual, conscious selection and hierarchization of values and being guided by them in all areas of their personal and professional lives. Axiological education helps to gain the ability to distinguish between good and evil, truth and falsehood, selfishness and altruism. A pedagogical approach to values has become the subject of many scientific considerations and discussions among parents and teachers. This article is a review of the relationships between value systems and upbringing.

Florian Znaniecki jako pedagogiczny marzyciel
Authors: Kwieciński Zbigniew
Published: January 2020

An outstanding sociologist and philosopher of culture did not consider himself a pedagogue and was not perceived as one. An analysis of his books written during periods of great global crises: The Fall of Western Civilization (1921) and The Social Role of a University Student (1940), indicates that the fundamental transformation of education, especially university education, is a necessary condition for the formation of a new “aristocracy of the spirit”, new creative elites, capable of leading the masses (people) to the revival and development of Western civilization. American universities are particularly well-suited to this function. Both the content and the language of these books confirms that Florian Znaniecki was a radical humanistic pedagogue.
Family-School-Partnership About Virtue Development
Authors: Bernasiewicz Maciej , Gierczyk Marcin
Published: January 2020

Many types of research appear to show that communication barriers and a bad relationship between teachers and parents can hinder the development of behavioral skills and cognitive capacities that enable some individuals to put their moral habits into their life. Teachers’ and parents’ common aim is to create in young people attitudes consistent with the given system of values. This article is a theoretical overview of the issues related to the family-school partnership about Virtue Development, on the basis of which the authors proposed a conceptual model of an interdependent and interrelated relationship between teachers and parents and demonstrated how the inclusion of parents, students and teachers in broadly understood activities for the benefit of others (people, animals, nature, etc.) is particularly valuable from the point of view of moral development in Polish schools.

Published: January 2020

Introduction: The retrograde approach is a modification that makes the percutaneous cystolitholapaxy (PCCL) a more trendy method, especially in operating rooms with limited facilities. The transurethral approach for bladder calculi lithotripsy by a laser has become popular among urologists. In this study, we investigate the feasibility and safety of retrograde assisted access for PCCL in comparison with transurethral cystolithotripsy by the holmium-YAG laser (Ho: YAG). Methods: According to the type of intervention, the patients were stratified to two matched groups. In the retrograde-assisted percutaneous cystolitholapaxy (RPCCL) group, a Benique was conducted through the urethra into the bladder; palpating the suprapubic region, an about 1.5 cm incision was done over the tip, then an Amplatz sheath was placed over it, treading into the bladder; further cystolitholapaxy was done by a routine order. In transurethral Ho: YAG laser lithotripsy (TULL) via 200 µm fiber vaporize the stone. Results: A total of 124 male patients with the mean age of 50.33±9.64 years and the average stone burden of 3.35±1.07 cm were included in the study. The most common cause of vesical calculi was spinal cord injury. Statistically significant differences were found in terms of the mean operation time in favor of the RPCCL group (P≤0.05) and the mean hospital stay in favor of the TULL group (P≤0.05). The stone-free rate (SFR) was 100% in both methods after a onemonth follow-up. None of the interventions changed to open surgery. There were not any major complications in both methods. Conclusion: RPCCL is a safe and effective method in bladder stone treatment and is applicable in medical centres without Ho: YAG equipment.

Published: January 2020

Introduction: Intense pulsed light (IPL) is one of the effective methods used to treat the signs of facial aging. However, its efficacy in improving the appearance of periorbital wrinkles has always been evaluated in the context of whole-face rejuvenation and not studied in its own right. Therefore, in this study, we sought to examine the effectiveness and side effects of IPL in periorbital skin rejuvenation. Methods: In this uncontrolled, open-label clinical trial, 38 patients referred to the Behrooz professional skin clinic for signs of periorbital skin aging were recruited. The patients underwent three treatment sessions with IPL at one-month intervals and were evaluated for treatment side effects after each session. Six months after the final IPL session, patients were examined to assess the level of symptom improvement. The patients were photographed at each treatment session and on the 6-month follow-up visit. Before and after treatment, the patient images were evaluated by two dermatologists unaffiliated with the study to determine the extent of improvement in the appearance of wrinkles and skin texture. Results: Six months’ post-treatment, excellent improvement was observed in 3 patients (9.1%), considerable improvement in 7 patients (21.2%), moderate improvement in 9 patients (27.3%), mild improvement in 9 patients (27.3%), and finally little or no improvement in 5 patients (15.1%). A comparison of improvement scores based on the Fitzpatrick skin phenotype did not show significant differences (P=0.674). Four patients (12.1%) were dissatisfied with the treatment, whilst 17 patients (51.5%) reported moderate to considerable satisfaction with IPL rejuvenation. Conclusion: During facial rejuvenation, IPL can be used to improve periorbital skin aging.

Introduction: The purpose of this study is to investigate the effect of a low-power laser on the proliferation, migration, differentiation of different types of mesenchymal stem cells (MSCs) in different studies. Methods: The relevant articles that were published from 2004 to 2019 were collected from the sources of PubMed, Scopus, and only the articles specifically examining the effect of a lowpower laser on the proliferation, differentiation, and migration of the MSCs were investigated. Results: After reviewing the literature, only 42 articles were found relevant. Generally, most of the studies demonstrated that different laser parameters increased the proliferation, migration, and differentiation of the MSCs, except the results of two studies which were contradictory. In fact, changing the parameters of a low-power laser would affect the results. On the other hand, the source of the stem cells was reported as a key factor. In addition, the combination of lasers with other therapeutic approaches was found to be more effective. Conclusion: The different parameters of lasers has been found to be effective in the proliferation, differentiation, and migration of the MSCs and in general, a low-power laser has a positive effect on the MSCs, helping to improve different disease models.
Cerebrospinal Fluid and Photobiomodulation Effects on Neural Gene Expression in Dental Pulp Stem Cells

Published: January 2020

Introduction: Dental pulp cells, a unique source of ectomesenchymal pluripotent stem cells, are originated from the skull neural crest. They are considered as one ideal source of cells for the regenerative medicine applications. Cerebrospinal fluid (CSF), a transparent fluid found in the brain and spinal cord, is enriched with electrolytes, proteins, and growth factors such as EGF, bFGF, BDNF, GDNF, and neuropeptides and can be utilized as a trigger in order to induce the neural differentiation. On the other hand, photobiomodulation (PBM), with the ability to prevent cell apoptosis, can induce cell proliferation by means of increasing the ATP synthesis in mitochondria and facilitating the secretion of the growth factors. In this research, we first aimed to isolate and culture the dental pulp stem cells (DPSCs) and subsequently to investigate their potential for neural differentiation. Methods: Human dental pulp stem cells (hDPSCs) were isolated from the pulp tissues using an outgrowth method and subsequently cultured. In order to access the cells’ differentiation potential, cells were firstly classified into four groups which were treated with CSF, gallium aluminum arsenide diode laser irradiation (808 nm; 30 mW power output) and a combination of both, while the fourth group was considered as the control. MTT assay was then used to examine the viability of cells following the treatments. After 4, 7, and 14 days the cell morphology in the treated groups was evaluated while RT-PCR was used in order to evaluate the Nestin and β-tubulinIII neural gene marker expressions. Results: It was shown that PBM has the ability to elevate the proliferation of DPSCs. Also, the differentiated morphology was obvious in the CSF treated group, especially on day 14 with the formation of three-dimensional (3D) structures. The results of gene expression analysis showed that on the fourth day of post-treatment, Nestin and β-tubulinIII gene expressions were reduced in all groups while a rising trend in their expression was observed subsequently on days 7 and 14. Conclusion: In accordance with previous studies, including functional and protein base researches, it has been demonstrated that CSF has a direct role in neural induction. Although past works have been significant, none of them shows a 3D structure. In this article, we investigated the dual effect of PBM and CSF. Initial results confirmed the upregulation of neural-related transcription factors. The 3D organization of the formed tissue could imply the initiation of organogenesis which has not been reported before. In sum, the dual effect of CSF and PBM has been shown to have the potential for contributing to the initiation of neurogenesis and organogenesis
“The Fruit of Many Years”: Bertrand Russell and Vera Brittain
Authors: Bishop Alan
Published: January 2020

In her dedicated promotion of feminism and pacifism, especially during the 1930s, Vera Brittain (1893–1970) was strongly influenced by Ber­trand Russell’s writings, especially Marriage and Morals (1929) and Which Way to Peace? (1936). Both were members of the Peace Pledge Union, and she continued as a sponsor after Russell abandoned his pac­ifism soon after the beginning of the Second World War. She admired his political and social activism in the aftermath of that war, endorsing it as much as her family situation allowed; and, as chairman of the Peace News board, Brittain intervened in Russell’s support when a dispute broke out between him and the editor. Although their rela­tionship was personally limited, Russell’s influence on her opinions and actions was profound.
Russell’s Corrected Page Proofs of Principia Mathematica
Authors: Linsky Bernard , Blackwell Kenneth
Published: January 2020

We report here on the set of complete proofs of Volumes I and II of Whitehead and Russell’s Principia Mathematica newly acquired by the Bertrand Russell Archives. These proof sheets, marked with a number of corrections, were likely bound for Russell by Cambridge University Press, though not exactly the same as the first edition. We assess the information to be gained from the texts and the corrections, most significantly around *110 in Vol. II and the lost dot of the empty relation  in Vol. I. All are in Russell’s hand and described in an appendix. We also note several revisions in the first edition that were made after these proofs. We discuss the provenance of the volumes, and Russell’s correspondence about proofs of PM with M. H. Dziewicki, but we find that there is insufficient evidence to determine the chain of possession from Russell to their discovery for sale in Australia in recent years.
Leszek Kołakowski: racionalidad comunicativa versus mito
Authors: Moreno Barreto Saturnino Javier
Published: January 2020

En filosofía llamamos absoluto a aquello que está desligado del todo, lo que es por sí mismo sin relación a nada. Lo absoluto es, entonces y por definición, inefable e incomunicable, siendo solo posible desvelar sus contornos a través del mito. Sin mito, señala Leszek Kołakowski (1927-2009), no es posible el conocimiento. En este trabajo veremos que el pensamiento del filósofo polaco se deja articular en torno al problema del fundamento y los límites del saber. Se trata de una cuestión que entendió como el anhelo de la filosofía: dar razón de ese absoluto que se manifiesta en la filosofía de la historia bajo el aspecto de la utopía de la fraternidad, y en la epistemología como la utopía de la certeza. Defenderemos, sin embargo, que ese no puede ser el anhelo de la filosofía, pues, en cuanto pretende proveer conocimientos, no puede evadir los límites de la intersubjetividad. En consecuencia, expondremos que la teoría de la acción comunicativa formulada por Jürgen Habermas da mejor cuenta de una racionalidad que encuentra en la comunicación ordinaria la facultad de dar y pedir razones sobre aquello que consideramos verdadero y correcto.
La representación de la dictadura en el cine de animación argentino
Authors: Fenoll Vicente
Published: January 2020

Las imágenes cinematográficas permiten la construcción colectiva de la memoria. La representación del desaparecido es un reto para el cine documental que afronta esta problemática en la reconstrucción de la memoria traumática. El objetivo de este trabajo es analizar las características de la animación utilizadas en la producción audiovisual argentina para abordar la dictadura de la Junta Militar. El corpus está compuesto por nueve obras que incorporan total o parcialmente la animación como estrategia de representación: Los rubios (Albertina Carri, 2003), El Tiempo y la Sangre (Alejandra Almirón, 2004), La Matanza (María Giuffra, 2005), Padre (Santiago Grasso, 2008), Infancia clandestina (Benjamín Ávila, 2011), Zamba en la Casa Rosada (Fernando Salem, 2012), La mirada perdida (Damian Dionisio, 2012), La parte por el todo (Gato Martínez, Santiago Nacif y Roberto Persano, 2015) y Las muñecas de la Tía Tita (MaXi BearZi, 2017). Desde una perspectiva cualitativa, se analiza el papel que juega la animación en estas obras. También se incorpora la opinión de los autores para determinar los elementos que favorecen su proliferación en el ámbito de la memoria. Los resultados del estudio revelan el potencial de la animación como instrumento terapéutico con el que mostrar de manera alegórica al desaparecido y, adicionalmente, conectar emocionalmente con el inconsciente del espectador. La vinculación de este formato a la infancia favorece también el establecimiento de puentes que acerquen la memoria de la dictadura a las nuevas generaciones, con el fin de consolidar los valores democráticos en la sociedad.
Effects of Soccer Match-Play on Unilateral Jumping and Interlimb Asymmetry: A Repeated-Measures Design

Bishop, C, Read, P, Stern, D, and Turner, A. Effects of soccer match-play on unilateral jumping and interlimb asymmetry: a repeated-measures design. J Strength Cond Res 36(1): 193–200, 2022—The aims of this study were two-fold: (a) determine the effects of repeated soccer match-play on unilateral jump performance and interlimb asymmetries and (b) examine associations between asymmetry and commonly reported external load variables collected during competition. Single-leg countermovement jumps and drop jumps were collected before and immediately after 5 soccer matches in elite academy soccer players. Global positioning system data were also collected during each match as part of the routine match-day procedures. Single-leg countermovement jump height and concentric impulse showed significant reductions after matches (p < 0.01; effect size [ES]: −0.67 to −0.69), but peak force did not (p > 0.05; ES: −0.05 to −0.13). Single-leg drop jump height and reactive strength also showed significant reductions after matches (p < 0.01; ES: −0.39 to −0.58). No meaningful reductions in asymmetry were present at the group level, but individual responses were highly variable. Significant associations between postmatch reactive strength asymmetry and explosive distance (r = 0.29; p < 0.05), relative explosive distance (r = 0.34; p < 0.05), high-speed running (r = 0.35; p < 0.05), and relative high-speed running (r = 0.44; p < 0.01) were observed. These findings show that unilateral jump tests are more appropriate than asymmetry to detect real change after soccer competition, and practitioners should be cautious about using asymmetry to inform decision-making during the temporal recovery period.

Sports performance is influenced by the interaction of several physical variables. For this reason, most sports need both strength and endurance capacities to maximize overall performance. Therefore, a combination of resistance and aerobic training, usually called concurrent training (CT), has been used recently as a way of simultaneously improving strength and aerobic performances according to the needs of a specific sport. This combination can be challenging and can influence training adaptations, being a problematic issue for coaches. The main objective is to provide coaches with a practical proposal for CT to improve athletes' performance in different sports.
