Selamat Datang Psikologi!
Authors: Gunadi Paul 
Published: September 2019

Sewaktu saya sedang berkuliah, seseorang pernah bertanya kepada ibu saya mengenai bidang studi apa yang sedang saya pelajari. Setelah mendengar jawaban bahwa saya sedang belajar psikologi, dengan serta merta ia menasehati ibu saya bahwa psikologi adalah ilmu yang melawan Tuhan dan sebaiknyalah saya menempuh bidang ilmu yang lain. Lebih dari 20 tahun kemudian, komentar tersebut tetap mewakili sebagian pandangan orang Kristen terhadap psikologi. Namun demikian, dengan rasa syukur saya harus mengatakan bahwa sambutan gereja-gereja terhadap sumbangsih ilmu psikologi pada umumnya adalah positif. Seminari pun telah merangkul disiplin ilmu ini dan memasukkannya sebagai mata kuliah ke dalam kurikulum pendidikan teologi.

Published: September 2019

The main focus of our research was the U16 age group since it is one of the most significant in terms of the young athlete’s future - probably professional - career. It was very helpful in research that this age group was a priority in the Basketball Academy of Debrecen’s program and they were competing in an international basketball league, in the European Youth Basketball League (EYBL). Thanks to the EYBL tournaments we have got a chance to analyze this youth category completely. For primer research we have chosen three teams, two Hungarian, and one Italian, to get an impression why is so important to play basketball at the international level in this age. We have made interviews with the coaches, organizers and the manager of the league to have an international comparison of this age group.

Introduction: Effects of physical activity on immune functions may largely depend on the type of activity, its intensity and duration. However, little information is available regarding the immunological effects of sporting activities in older ages.
The aim of our study was to examine the changes in a wide spectrum of lymphocyte subtypes after a period of regular workout among healthy women of different ages.
Methods: In our study, we enrolled 16 elderly women (between ages of 60-75 years) formerly not engaged in regular physical activity, who took part in lightweight conditioning gymnastic exercise program. Eight young athletes and 26 young adults with sedentary lifestyle served as controls. The percentages of peripheral NK, NKT cells, T and B lymphocyte subtypes were determined by flow cytometry based on the staining of extracellular markers and intracellular cytokines.
Results: Lymphocyte subgroups did not differ between the groups of young athletes and young adults with sedentary lifestyle. However, in elderly women, levels of NKT cells were lower, while ratios of T helper / T cytotoxic cells were higher compared to younger individuals. At the end of exercise program, in elderly women, percentages of naive B cells decreased, while levels of switched-memory B cells increased. Furthermore, proportions of Th2 cells increased, while levels of immunosuppressive CD4+CD127-CD25bright Treg cells decreased as the result of regular exercise.
Conclusion: Differences observed after lightweight exercise programs reflect a presumably enhanced immunoreactivity and increased ability for immune responses in older ages.

Abstract
The Low-Frequency Array radio telescope discovered the 707 Hz binary millisecond pulsar (MSP) J0952−0607 in a targeted radio pulsation search of an unidentified Fermi gamma-ray source. This source shows a weak energy flux of F

γ
= 2.6 × 10−12 erg cm−2 s−1 in the energy range between 100 MeV and 100 GeV. Here we report the detection of pulsed gamma-ray emission from PSR J0952−0607 in a very sensitive gamma-ray pulsation search. The pulsar’s rotational, binary, and astrometric properties are measured over 7 years of Fermi-Large Area Telescope data. For this we take into account the uncertainty on the shape of the gamma-ray pulse profile. We present an updated radio-timing solution now spanning more than 2 years and show results from optical modeling of the black-widow-type companion based on new multiband photometric data taken with HiPERCAM on the Gran Telescopio Canarias on La Palma and ULTRACAM on the New Technology Telescope at ESO La Silla (based on observations collected at the European Southern Observatory, Chile; programme 0101.D-0925, PI: Clark, C. J.). PSR J0952−0607 is now the fastest-spinning pulsar for which the intrinsic spin-down rate has been reliably constrained (

). The inferred surface magnetic field strength of

is among the 10 lowest of all known pulsars. This discovery is another example of an extremely fast spinning black-widow pulsar hiding within an unidentified Fermi gamma-ray source. In the future such systems might help to pin down the maximum spin frequency and the minimum surface magnetic field strength of MSPs.
Implications from ASKAP Fast Radio Burst Statistics
Authors: Lu Wenbin , Piro Anthony L. 
Published: September 2019

Abstract
Although there has recently been tremendous progress in studies of fast radio bursts (FRBs), the nature of their progenitors remains a mystery. We study the fluence and dispersion measure (DM) distributions of the ASKAP sample to better understand their energetics and statistics. We first consider a simplified model of a power-law volumetric rate per unit isotropic energy dN/dE ∝ E
−γ
with a maximum energy E
max in a uniform Euclidean universe. This provides analytic insights for what can be learned from these distributions. We find that the observed cumulative DM distribution scales as N(>DM) ∝ DM5−2γ
(for γ > 1) until a maximum DMmax above which bursts near E
max fall below the fluence threshold of a given telescope. Comparing this model with the observed fluence and DM distributions, we find a reasonable fit for γ ∼ 1.7 and E
max ∼ 1033 erg Hz−1. We then carry out a full Bayesian analysis based on a Schechter rate function with cosmological factors. We find roughly consistent results with our analytical approach, although with large errors on the inferred parameters due to the small sample size. The power-law index and the maximum energy are constrained to be γ ≃ 1.6 ± 0.3 and

(68% confidence), respectively. From the survey exposure time, we further infer a cumulative local volumetric rate of

(68% confidence). The methods presented here will be useful for the much larger FRB samples expected in the near future to study their distributions, energetics, and rates.
Variations in α-element Ratios Trace the Chemical Evolution of the Disk

Published: September 2019

Abstract
It is well established that the chemical structure of the Milky Way exhibits a bimodality with respect to the α-enhancement of stars at a given [Fe/H]. This has been studied largely based on a bulk α abundance, computed as a summary of several individual α-elements. Inspired by the expected subtle differences in their nucleosynthetic origins, here we probe the higher level of granularity encoded in the inter-family [Mg/Si] abundance ratio. Using a large sample of stars with APOGEE abundance measurements, we first demonstrate that there is additional information in this ratio beyond what is already apparent in [α/Fe] and [Fe/H] alone. We then consider Gaia astrometry and stellar age estimates to empirically characterize the relationships between [Mg/Si] and various stellar properties. We find small but significant trends between this ratio and α-enhancement, age, [Fe/H], location in the Galaxy, and orbital actions. To connect these observed [Mg/Si] variations to a physical origin, we attempt to predict the Mg and Si abundances of stars with the galactic chemical evolution model Chempy. We find that we are unable to reproduce abundances for the stars that we fit, which highlights tensions between the yield tables, the chemical evolution model, and the data. We conclude that a more data-driven approach to nucleosynthetic yield tables and chemical evolution modeling is necessary to maximize insights from large spectroscopic surveys.

Abstract
We report the discovery of six active galactic nuclei (AGNs) caught “turning on” during the first nine months of the Zwicky Transient Facility (ZTF) survey. The host galaxies were classified as low-ionization nuclear emission-line region galaxies (LINERs) by weak narrow forbidden line emission in their archival SDSS spectra, and detected by ZTF as nuclear transients. In five of the cases, we found via follow-up spectroscopy that they had transformed into broad-line AGNs, reminiscent of the changing-look LINER iPTF16bco. In one case, ZTF18aajupnt/AT2018dyk, follow-up Hubble Space Telescope ultraviolet and ground-based optical spectra revealed the transformation into a narrow-line Seyfert 1 with strong [Fe vii, x, xiv] and He ii
λ 4686 coronal lines. Swift monitoring observations of this source reveal bright UV emission that tracks the optical flare, accompanied by a luminous soft X-ray flare that peaks ∼60 days later. Spitzer follow-up observations also detect a luminous mid-infrared flare, implying a large covering fraction of dust. Archival light curves of the entire sample from CRTS, ATLAS, and ASAS-SN constrain the onset of the optical nuclear flaring from a prolonged quiescent state. Here we present the systematic selection and follow-up of this new class of changing-look LINERs, compare their properties to previously reported changing-look Seyfert galaxies, and conclude that they are a unique class of transients well-suited to test the uncertain physical processes associated with the LINER accretion state.
Effect of Morphological Asymmetry between Leading and Following Sunspots on the Prediction of Solar Cycle Activity
Authors: Iijima H. , Hotta H. , Imada S. 
Published: September 2019

Abstract
The morphological asymmetry of leading and following sunspots is a well-known characteristic of the solar surface. In the context of the large-scale evolution of the surface magnetic field, the asymmetry has been assumed to have only a negligible effect. Using the surface flux transport (SFT) model, we show that the morphological asymmetry of leading and following sunspots has a significant impact on the evolution of the large-scale magnetic field on the solar surface. By evaluating the effect of the morphological asymmetry of each bipolar magnetic region (BMR), we observe that the introduction of asymmetry to the BMR model significantly reduces the contribution to the polar magnetic field, especially for large and high-latitude BMRs. Strongly asymmetric BMRs can even reverse regular polar field formation. The SFT simulations based on the observed sunspot record show that the introduction of morphological asymmetry reduces the root-mean-square difference from the observed axial dipole strength by 30%–40%. These results indicate that the morphological asymmetry of leading and following sunspots has a significant effect on the solar cycle prediction.
Binary Mergers near a Supermassive Black Hole: Relativistic Effects in Triples
Authors: Liu Bin , Lai Dong , Wang Yi-Han 
Published: September 2019

Abstract
We study the general relativistic (GR) effects induced by a spinning supermassive black hole on the orbital and spin evolution of a merging black hole binary (BHB) in a hierarchical triple system. A sufficiently inclined outer orbit can excite Lidov–Kozai eccentricity oscillations in the BHB and induce its merger. These GR effects generate extra precessions on the BHB orbits and spins, significantly increasing the inclination window for mergers and producing a wide range of spin orientations when the BHB enters LIGO band. This “GR-enhanced” channel may play an important role in BHB mergers.
Le « Périscope »
Authors: Petitjean Christophe 
Published: September 2019

Cet article fait suite à un atelier animé par l’auteur lors du congrès IFAT de novembre 2018. Le thème du congrès était « l’espoir ». La démarche présentée intéressera tous les transactionnalistes qui, dans l’accompagnement d’un client, se questionnent : » dois-je valider les espoirs et risquer de renforcer des méconnaissances, ou bien confronter la personne avec la réalité et risquer de la décourager ? ». L’approche du PÉRISCOPE aide à trouver un juste équilibre, en levant doucement le voile sur les contaminations de l’Adulte. C. Petitjean présente et commente deux accompagnements dans deux domaines très différents (la santé et le travail), de manière très didactique. Pas à pas, le lecteur découvre comment, grâce à un questionnement respectueux guidé par les « lentilles » des états du moi, et grâce à une schématisation des réponses, le client, partant de ses espoirs, accède peu à peu à ses peurs masquées et à une conscience plus claire de sa situation.

Siqueiros et les aléas du discours d’autorité
Authors: Plâa Monique 
Published: September 2019

Le travail analyse deux formes du discours, celui de Siqueiros qui n’a cessé de définir et de défendre le muralisme et celui d’Octavio Paz, le prestigieux poète et essayiste qui à ce jour reste le critique qui fait autorité quand il s’agit de muralisme. Avec une rhétorique agressive et des formulations d’apparence sectaires, incessamment, des décennies durant et ce encore en 1966, alors même que le Mexique célèbre son œuvre, Siqueiros doit sans encore et toujours, contre tout et contre tous défendre le muralisme comme mouvement uni et cohérent et comme esthétique au service d’une philosophie de l’histoire. Ce faisant, il fait la preuve, que sa manière de voir les choses ne parvient pas à faire autorité. Paz, au nom de l’autorité que lui vaut son statut de poète et d’essayiste prestigieux, impose naturellement une lecture du muralisme qui nie subtilement ce qui, dans le discours et la pratique de Siqueiros, en fait le fondement : philosophie de l’histoire, constante élaboration d’une esthétique au service de la figuration et revendication d’une figuration au service d’un art engagé sont tenus pour de simples et malencontreux travers. Ce faisant, l’autorité de Paz en récusant le monde des idées qui le sous-tend prive le muralisme d’une approche critique qui rende compte de la subtile complexité de son élaboration et de la portée de ses enjeux.

Published: September 2019

This study investigated the psychological wellbeing and body perception among young Italian people. Drinking, eating, and sexual behaviors have been examined in relation to body mass index (BMI) and psychological well-being by EPOCH framework. This was a cross-sectional observational study conducted on Italian adolescent and young adult population through an online survey. Qualitative and quantitative data on lifestyle, BMI classes, and psychological characteristics of wellness in youth were obtained from a sample of 1221 Italian participants using a self-report questionnaire on body perception and habits, a socio-demographics inventory, and the EPOCH measure. Findings suggest that being underweight or overweight is associated with various factors, including gender, self-control regarding food, perception of one’s body, and the happiness domain. EPOCH framework revealed the psychological wellness of girls and young women did not seem strongly affected by BMI, though Perseverance and Happiness seemed reduced with increasing BMI. The Engagement, Optimism, and Connectedness domains were not significantly affected by the BMI variable. On the contrary, Perseverance and Happiness seemed reduced with increasing BMI and were related to physical shape. Our study offers a new perspective: promoting the development of positive psychological characteristics since adolescence to boost quality of life by improving wellness, by EPOCH approach could be functional reinforcing specific psychological aspects in young generations regarding future wellness, improving the positive perception and management of their own health.

Published: September 2019

Abstract
The bilingual advantage and its effect on executive function (EF) are among the major concerns of researchers in the field of bilingualism. Nevertheless, the bilingual effect on critical thinking has not yet received the attention it truly deserves. The present study aimed to investigate the bilingual effect on critical thinking disposition (CTD) and its relationship to age, age of onset (AoO), and L2 proficiency. An experimental design was adopted to study the impact of bilingualism on CTD. Correlational designs were then used to investigate the association between L2 proficiency and age of bilinguals with their CTD scores. The sample included 286 participants, consisting of 143 bilinguals, carefully matched with 143 monolinguals based on age and socioeconomic status. The bilinguals were then divided into two groups of early bilinguals (AoO = 10 years or less) and late bilinguals (AoO = 11 years or more). Their L2 proficiency and performance on the University of Florida Critical Thinking Disposition Inventory were measured and compared. The results indicate an advantage in CTD in favor of the bilinguals, with no significant difference between early and late bilinguals. A larger effect size was observed with an elevation in the age of the bilinguals. A positive association was found between L2 proficiency and the bilinguals’ CTD, with a weak correlation between education and CTD scores. The results are also compared with those of the bilingual effect on EF.

O icozeiro (Capparis yco) é uma planta endêmica do semiárido que ocorre na Caatinga do Nordeste brasileiro, desconhecida nas suas potencialidades e sua capacidade de propagação via seminal sob condições de restrições hídricas. Este trabalho objetivou avaliar os componentes de crescimento e a qualidade de mudas de icozeiro produzidas com águas salinas e uso de fibra de coco como cobertura morta. O experimento foi instalado em delineamento inteiramente casualizado, com quatro repetições, em arranjo fatorial 6 x 2, correspondente a seis níveis de condutividade elétrica da água aplicada (0,5; 2,5; 4,5; 6,5 8,5 e 10,5 dS m-1), no substrato sem e com cobertura morta. Foram avaliados o índice de velocidade de emergência, tempo médio de emergência, altura da planta, diâmetro caulinar, área foliar, massa seca da parte aérea, massa seca da raiz, massa seca total e índice de qualidade de Dickson. A aplicação de água de alto teor salino afetou negativamente os atributos de crescimento altura das plantas, diâmetro caulinar, área foliar, massa seca da parte aérea, massa seca das raízes e massa seca total das mudas de icozeiro. A cobertura com fibra de casca de coco inibiu o crescimento e reduziu a qualidade das mudas de icozeiro. O uso da fibra de casca de coco como cobertura morta não é recomendado para produção de mudas de icozeiro.

AbstractIn cochlear implants, the electrode insertion trauma during surgery can cause damage residual hearing. Preserving the residual hearing is an important challenge and the localized administration of drugs, such as steroids, is one of the most promising ways, but remains a challenge. Here, a microscaffold cochlear electrode array (MiSCEA) consisting of a microfabricated flexible electrode array and a 3D microscaffold for steroid reservoir is reported. The MiSCEA without loaded drug is tested by measuring the electrically evoked auditory brainstem response of the cochlea in guinea pigs (n = 4). The scaffold is then coated with steroid (dexamethasone) encapsulated in polylactic‐co‐glycolic acid and the continuous release of the steroid into artificial perilymph during six weeks is monitored. The steroid‐containing scaffolds are then implanted into guinea pigs (n = 4) and threshold shifts are analyzed for four weeks by measuring the acoustically evoked auditory brainstem response. The threshold shifts tend to be lower in the group implanted with the steroid‐containing MiSCEAs. The feasibility of 3D MiSCEA opens up the development of potential next‐generation cochlear electrode with improved steroid release dynamics into cochlea.
