Abstrak Mengasuh anak merupakan kewajiban orang tua. Dalam pelaksanaanya tidak semua orang tua dapat menjalankan pola asuh sesuai dengan keutuhan dari anak. Orang tua seringkali tidak menyadari bahwa telah melakukan perlakuan yang salah dalam mengasuh anak. Hal ini berkaitan dengan budaya dalam mengasuh anak dalam masyarakat. Banyak kasus kekerasan yang secara tidak langsung dilakukan oleh orang tua. Untuk mengatasi permasalahan tersebut, diperlukan adanya teknik parenting ynag dimiliki oleh oramg tua. Teknik kajian yang digunakan dalam artikel ini adalah kualitatfi dengan tujuan untuk memperoleh gambaran secara mendalam mengenai teknik parenting yang dilakukan oleh orang tua. Informan merupakn orang tua yang memmpunyai anak dan melakukan pengasuhan. Orang tua yang menjadi informan terbagi atas orang tua yang salah satu bekerja dan keduanya bekerja. Hasil kajian ini menunjukkan bahwa orang tua yang menjadi informan telah menjalankan teknik parenting seperting yang diemukakan oleh Grusec. Hal ini dapat dilihat dari jawaban yang bersifat positif dari setiap indikator kajian. Dengan demikian informan telah mengetahui dan memahami dan menjalankan teknik parenting. Abstract Parenting is an obligation of parents. In the implementation not all parents can carry out parenting according to the integrity of the child. Parents often do not realize that they have done wrong treatment in parenting. This is related to the culture of parenting in the community. Many cases of violence are indirectly carried out by parents. To overcome this problem, there is a need for parenting techniques that are owned by older people. The study technique used in this article is qualified in order to obtain an in-depth picture of parenting techniques carried out by parents. Informants are parents who have children and do care. Parents who become informants are divided into parents whose one works and both work. The results of this study indicate that parents who were informants had carried out parenting techniques as suggested by Grusec. This can be seen from the positive answers from each study indicator. Thus the informant has known and understood and carried out the parenting technique.

Published: January 2019

Abstract
The problem of longitudinal shear of bimaterial with thin nonlinear elastic inclusion at the interface of matrix materials is considered. Solution of the problem is constructed using the boundary value problem of combining analytical functions and jump functions method. The model of the thin inclusion with nonlinear resilient parameters is built. Solution of the problem is reduced to a system of singular integral equations with variable coefficients. The convergent iterative method for solving such a system is offered for various nonlinear strain models, including Ramberg-Osgood law. Numerical calculations are carried out for different values of non-linearity characteristic parameters for the inclusion material. Their parameters are analysed for the tensely-deformed matrix under loading a uniformly distributed shear stresses and for a balanced system of the concentrated forces.
Characteristic Equations of the Standard and Descriptor Linear Electrical Circuits of Integer and Fractional Orders
Authors: Kaczorek Tadeusz 
Published: January 2019

Abstract
The problem of calculation of the characteristic equations of the standard and descriptor linear electrical circuits of integer and fractional orders is addressed. It is shown that the characteristic equations of standard and descriptor linear electrical circuits are independent of the method used in their analysis: the state space method, the mesh method and the node method. The considerations are illustrated by examples of standard and fractional linear electrical circuits.

Published: January 2019

Abstract
This study aimed to identify the game-related statistics that discriminated between Euroleague basketball players and European basketball players playing in the NBA, when competing in the same event (EuroBasket 2015). There was a total of 78 matches played by 24 teams in two groups of analysis: NBA, participants in the European Championship who played in the NBA season of 2014-2015 (n = 26); Euroleague, participants in the European Championship who played in the Euroleague season of 2014-2015 (n = 82). The players’ performance variables were normalized to the time they spent on the court. To identify which variables best discriminated between the NBA and the Euroleague performance profiles, a descriptive discriminant analysis was conducted. Structure coefficients (SC) from the matrix greater than |0.30| were interpreted as meaningful contributors to discriminating between the groups. The results revealed a significant function (p = 0.008, canonical correlation of 0.51, Λ = 0.74, reclassification = 84.2%) and substantial performance differences in game-related statistics much related to the influence of body size (body height and mass), such as two-point field goals made (SC = 0.42) and missed (SC = 0.40), free-throws made (SC = 0.55), defensive rebounds (SC = 0.62), blocks (SC = 0.48) and suffered fouls (SC = 0.34). No differences were found at the level of game-related statistics indirectly related to perception, such as assists, turnovers or steals. Also, the greater body size in NBA players was likely related to higher variability in performance, thus, being an important topic for coaches and recruiters to analyse.
A Video-Based Method to Quantify Stroke Synchronisation in Crew Boat Sprint Kayaking
Authors: Tay Cheryl Sihui , Kong Pui Wah 
Published: January 2019

Abstract
The study aimed to quantify stroke synchronisation in two-seater crew boat sprint kayaking (K2) using a video-based method, and to assess the intra- and inter-rater reliabilities of this method. Twelve sub-elite sprint kayakers (six males and six females) from a national team were paired into six single-gender K2 crews. The crews were recorded at 120 Hz with a sagittal-view video camera during 200-m time trials. Video analysis identified four meaningful positions of a stroke (catch, immersion, extraction and release). The timing difference (termed “offset”) between the front and back paddlers, within each K2, at each stroke position was calculated, with zero offset indicating perfect synchronisation. Results showed almost perfect intra-rater reliability of this method. The intra-class correlation (ICC) ranged from .87 to 1.00, and standard error of measurement ( SEM) from 0 to 5 milliseconds (ms). Inter-rater reliability was substantial to almost perfect (ICC .72 – .94, SEM 2 – 6 ms). On average, 35 strokes were analysed for each crew and the mean offset was 17 ms, or 5.7% of water phase duration. Crews were more synchronised at the catch (11 ms, 3.8%) than the release (21 ms, 7.2%). However, the stroke synchronisation profiles of the six sub-elite crews varied considerably from each other. For example, the best performing male and female crews had directly contrasting profiles. This suggests that there is no universal stroke synchronisation profile for well-trained sprint kayakers. This video-based method may aid future investigations on improving performance.
Cognitive Scripts, Anxiety and Styles of Coping with Stress in Teenagers Practising Sports
Authors: Basiaga-Pasternak Joanna 
Published: January 2019

Abstract
The aim of the study was to present the relationships between the way of perceiving oneself and the world by young athletes, the cognitive anxiety and the ways of coping with stress. The target group consisted of 222 participants (114 boys and 108 girls) aged 16–20, students of sports-profiled secondary schools. The participants specialised in both winter and summer sports, as well as in individual and team sport disciplines. The following tools were implemented: Attitudes to Intrapersonal, Interpersonal and to the World Questionnaire, Coping Inventory for Stressful Situations (CISS) and Sport Anxiety Scale. The study showed that negative perception of oneself and others increases the level of cognitive anxiety and decreases the tendencies to search for social contacts in the face of stress. With regard to the positive image of oneself and others, the opposite was observed. The above relationships refer mainly to girls who practise sports.

Abstract
The purpose of this study was to examine relations among reinvestment, self-regulation, and perception of choking under pressure in skilled tennis players. Participants were 160 collegiate players from the NCAA Division I in the U.S. and the 1st League in Japan. Participants completed questionnaires assessing reinvestment (conscious motor processing and movement self-consciousness), self-regulation, and perception of choking under pressure. Results of correlation analysis indicated self-regulatory factors were positively related to reinvestment conscious motor processing, but not with reinvestment movement self-consciousness. Self-efficacy and movement self-consciousness of reinvestment were found to predict one’s perception of choking under pressure. Results of simultaneous entry multiple regression revealed that tennis players who had low self-efficacy and were concerned about making a good impression with their movements were more likely to perceive that they choked during tennis matches. Additionally, Japanese players reported less self-regulation skills and a higher perception of choking under pressure than American players, suggesting the need for additional research on cross-cultural differences. Overall, these results suggest that self-efficacy may protect athletes from choking, but movement self-consciousness may lead athletes to choke during tennis games.

Abstract
The study compares the effect of an exercise-based cardiac rehabilitation program with a program combining physical exercise and lower extremity neuromuscular electrical stimulation (NMES) on the recovery of patients with chronic heart failure (CHF) with NYHA II-III symptoms. Seventy two patients with stable CHF were randomly distributed to four groups that received exercise-based cardiac rehabilitation and pharmacological treatment. Groups I and II were additionally administered NMES (35 Hz and 10 Hz, respectively) and in Group III sham NMES was applied. Group IV (controls) received solely pharmacological and exercise treatment. Exercise tolerance and quality of life were assessed in patients pre-treatment and at week 3. Three weeks of rehabilitation induced significant increases (p < 0.05) in the distance covered in the 6-minute walk test, the metabolic equivalent (MET), the duration of the treadmill exercise stress test, the left ventricle ejection fraction (LVEF) and improved quality of life in all groups, but between-group differences were not significant (p > 0.05). In none of the groups were the left ventricle end-systolic and end-diastolic diameters (mm) measured at week 3 significantly different from their baseline values (p > 0.05). Exercise-based cardiac rehabilitation contributed to higher exercise tolerance, LVEF and quality of life of CHF patients (NYHA II-III), contrary to cardiac rehabilitation combined with lower extremity NMES (35 Hz and 10 Hz) that failed to induce such improvements. More research is necessary to assess the therapeutic efficacy of NMES applied to CHF patients with NYHA IV symptoms.
Parameters of the Transition from a Cultural to a Political Program by the Czech and Slovak Elites in the Mid-19th Century
Authors: Doubek Vratislav 
Published: January 2019

Abstract
This article examines the rise of the nascent intellectual and business bourgeois elites of the Czechs and Slovaks, focusing on the transformation of their cultural program into a political one. The article takes a comparative approach and investigates the relationship of political programs to prepolitical identities, zooming in on the parameters of a broader Czech and Slovak state identity, including the role of the center (Vienna, Pest, Prague, or Pressburg) or language (analyzing both its unifying and divisive roles in bridging the ideas and visions of the emerging local elites). As I argue, in the case of the Czech and Slovak nationalist movements, we can observe a transition from a prepolitical to the political program in the mid-19th century itself.
Prospek Penelitian Artefak Perunggu Temuan Kerinci Melalui Analisis Metalurgi
Authors: Sunliensyar Hafiful Hadi 
Published: January 2019

Temuan artefak perunggu dalam se-abad terakhir di dataran Kerinci diteliti hanya sebatas pada kajian deskripsi dan ikonografi semata. Seringkali data yang didapat belum begitu akurat untuk merekonstruksi budaya masyarakatnya pada masa lampau. Apalagi temuan-temuan tersebut tidak kontekstual lagi. Analisis metalurgi yang telah banyak dilakukan peneliti terhadap temuan artefak perunggu di tempat lain, memberi kesempatan untuk ‘membongkar’ kembali artefak perunggu Kerinci agar dilakukan kajian melalui analisis metalurgi dengan studi komparatif. Melalui pendekatan induktif dalam tulisan ini, penulis mencoba memberikan gambaran tentang prospek penelitian artefak perunggu Kerinci melalui analisis metalurgi. Beberapa prospek penelitian ke depan antara lain: (1) aspek teknis pembuatan artefak tersebut; (2) aspek sosial-ekonomi seperti penelitian jalur perdagangan kuna ke Kerinci pada masa klasik; (3) migrasi artefak atau ideofak mengenai teknologi pembuatan perunggu dari Dongson ke wilayah Kerinci; (4) penelitian mengenai permasalahan apakah artefak perunggu Kerinci diimpor atau diproduksi secara lokal.

El componente pedagógico en la formación artística y cultural (0 del trasluz civilizatorio)
Authors: Horta Mesa Aurelio A. 
Published: January 2019

En las disímiles variaciones de esa faena imperial de la razón actuante como lo es el acto educativo, aquella que se ocupa del hallazgo y enriquecimiento de la Sensibilidad Civilizatoria, a través de su ejercicio instructivo/orientador, nos enfrenta a no pocas encrucijadas de compleja descripción.No pretendo significar en esta ocasión, los intrincados nudos de esta praxis que ya he ubicado en términos de “práctica pedagógica confrontada” , sino de reiterar cómo el camino hacia una intención epistemológica de la formación artística en nuestro contexto, nos obliga a la par de la búsqueda de metodologías o preceptos, a priorizar cual es el sentido y finalidad de la formación artística en atención al encargo educativo. Para este peculiar orden de reconocimiento de la conciencia y capacidad práctica del hombre que lo compulsa en los afanes hacia el triunfo de sus íntimas y públicas glorias, resulta de justa estimación esa inteligencia americana, siempre franqueadora ante muy diversas disyuntivas, ya advertidas por Alfonso Reyes.
Formalismo, Abstracción, rigor y dificultad en la matemática
Authors: Gutiérrez Hoyos Hernando 
Published: January 2019

He aquí cuatro términos que usualmente se confunden como sinónimos cuando se intenta hacer una caracterización de la matemática por parte de personas no especializadas en esta disciplina. La confusión llega a presentarse, incluso, entre personas que han recibido algún tipo de formación matemática pues no es raro encontrarse divulgadores de la materia que no establezcan claramente las diferencias y relaciones que existen entre estos términos.Quienes han tenido oportunidad de acercarse a la matemática indagando sobre la naturaleza de sus conceptos y la estructuración del conocimiento matemático, por encima de la simple manipulación de los procesos operativos asociados y/o derivados de estos conceptos, saben que existen relaciones pero también diferencias entre los cuatro términos del enunciado que contribuyen, precisamente, a la configuración unitaria de la diversidad que es, muy seguramente, una de las características esenciales de la matemática.Con el fin de estimular este acercamiento, que necesariamente debemos promover, a la matemática a través de conductas diferentes de la tradicional operatividad mecánica; voy a intentar presentar de una manera sencilla (ojalá la sencillez no desvirtúe los conceptos) cada uno de estos términos y aclarar las confusiones más frecuentes en la interpretación de ellos.
