ABSTRACT: Today, humans are always faced with the complexity of the acute world situation. This situation is nothing but an increasingly worsening environmental crisis. This emergency situation is inseparable from the increasingly exalted anthropocentric ego. The assumption that eliminates intrinsic value to other ecosystems and the wrong way of life leads to the separation of relations between humans and the surrounding reality.The interdependent context between all ecosystems is degraded due to the wrong attitude of life from humans. The loss of the relationship brought a variety of environmental damage which caused the destruction of human existence itself. Poverty, hunger, war, global warming, floods and drought are a few of the critical phenomena of nature. For these increasingly emergency natural phenomena, this thesis is written as a critical reflection for humans to re-examine their nature as religious, social and ecological creatures as well as concrete action that must be done to reconstruct relations (reconciliation) with nature, with the surrounding environment and especially reconciliation with his own life through ecological metanoia and a new lifestyle.Â  KEYWORDS: relation, antrophosentrism ego, ecological exigent, multidimensional perspective, awareness, reconciliation, repentance and new lifestyle.

La estrategia del debate abre un horizonte de reflexión en cuanto a la preservación del medio ambiente y la interacción hombre-naturaleza. El objetivo general de la investigación fue demostrar el impacto de la Estrategia del Debate en el fortalecimiento de conciencia ambiental en los estudiantes del II ciclo de Educación Inicial de la Universidad Nacional Interculturalidad de La Amazonia, Pucallpa. Se utilizó el enfoque cuantitativo y cualitativo y el diseño preexperimental y el instrumento, el cuestionario. El impacto de la Estrategia del Debate en el fortalecimiento de conciencia ambiental fue significativo con (p <0,05). Apoyado con el estudio cualitativo con mejoras en responsabilidad ecológica, destino del planeta y aún más, su sostenibilidad. Esto se logra a través del diálogo regido por el proceso de argumentación, a fin de generar intervenciones preventivas en la solución de problemas; de manera que el participante comprenda que forma parte de un gran todo llamado medio ambiente, y que lo debe proteger. Lo afirmado es corroborado por el pensamiento de Aldous Huxley: “La conciencia solo es posible a través del cambio; el cambio solo es posible a través del movimiento”.
Estimaciones de pasivos ambientales para acrecentar la contabilidad tridimensional y la sostenibilidad integral en las empresas mineras

Published: February 2019

En el balance del ejercicio de una empresa, el “pasivo” es el conjunto de deudas que minuciosamente se analizan y registran contablemente para su contraposición con el “activo”, existe un particular tipo de pasivo que raras veces es contabilizado: el “pasivo ambiental”, que equivale a la suma de todos los daños no compensados producidos en forma directa e indirecta al ambiente, que hacen posible las actividades productivas. Resulta difícil la valorización económica de los costos ambientales dado que muchos bienes no son intercambiables en el mercado, algunos caracterizados como intangibles, por ello el objetivo de la investigación se centró en las estimaciones de pasivos ambientales, mediante la aplicación de un software para ser contabilizados por las empresas mineras de la región Huánuco acrecentando la contabilidad tridimensional y la sostenibilidad integral. El estudio se circunscribe dentro de una investigación aplicada, cuantitativa, cualitativa, transversal, descriptiva, correlacional, explicativa, no experimental, deductiva, documental y de campo. Se empleó la técnica de la encuesta para recolectar la información. Los resultados indicaron que las empresas mineras generan pasivos ambientales que no son contabilizados. Se concluye que las estimaciones de pasivos ambientales permiten la sostenibilidad integral de la contabilidad en las dimensiones ambiental, social y económica.

Es indiscutible la relevancia de la familia en la sociedad, los padres son responsables directos en la formación de los pequeños, preparándolos para la vida, independientes y productivos para la sociedad. En este contexto, se buscó determinar la relación existente entre la Dinámica Familiar y el Desarrollo Psicosocial de los estudiantes de Educación Primaria de una Institución Educativa Privada de Punto Fijo, Estado Falcón – Venezuela. La investigación fue descriptiva correlacional, con diseño no experimental, de campo, transeccional. El muestreo fue no probabilístico, de tipo intencional, conformado por 28 niños de 1er grado y 24 niños de 2do grado de 6 a 8 años cumplidos, sin trastornos sensoriales, cognitivos o sociales. El desarrollo psicosocial fue evaluado a través de una guía de observación estructurada y la dinámica familiar con un cuestionario que evaluó vínculos familiares, contactos, procesos, pilares y contexto familiar. Los resultados, al aplicar el índice de correlación de Pearson permiten confirmar la hipótesis donde se establece que la Dinámica Familiar incide en el Desarrollo Psicosocial de los niños, pero de manera débil (0.09); es decir, para que se dé un desarrollo infantil óptimo debe existir un entorno familiar y social que lo favorezca. Se concluye que la dinámica familiar en sus dimensiones: vínculos familiares, contactos, procesos, pilares y contexto familiar sustenta el acercamiento de los miembros de la familia, estimulando el desarrollo psicosocial mediante conductas de interacción y autocontrol en determinadas situaciones.

Published: February 2019

There are numerous types of pathological changes in human immunodeficiency virus (HIV)-associated neurocognitive disorder (HAND), including apoptosis of neurons. HIV-1 transactivator of transcription (Tat) protein, which is encoded by HIV-1, may promote apoptosis in HAND. Forkhead box O3 (FOXO3) is a multispecific transcription factor that has roles in many biological processes, including cellular apoptosis. The aim of this study was to determine whether FOXO3 is activated by HIV-1 Tat and to investigate its role in neuronal apoptosis in HAND. We employed tissue staining and related molecular biological experimental methods to confirm our hypothesis. The in vivo experimental results demonstrated that the expression of nuclear FOXO3 increased in the apoptotic neurons of the cerebral cortexes of rhesus macaques infected with simian human immunodeficiency virus (SHIV). The in vitro investigation showed that HIV-1 Tat activated FOXO3, causing it to move from the cytoplasm to the nucleus via the c-Jun N-terminal kinase (JNK) signaling pathway in SH-SY5Y cells. Moreover, FOXO3 down-regulated expression of the anti-apoptosis gene B-cell lymphoma 2 (Bcl-2) and up-regulated the expression of the pro-apoptosis gene Bcl-2-like 11 (Bim) after entering the nucleus, eventually causing cellular apoptosis. Finally, reduction of nuclear FOXO3 reversed cellular apoptosis. Our results suggest that HIV-1 Tat induces FOXO3 to translocate from the cytoplasm to the nucleus via the JNK signaling pathway, leading to neuronal apoptosis. Agents targeting FOXO3 may provide approaches for restoring neuronal function in HAND.
Intuitive human interface to a scanning tunnelling microscope: observation of parity oscillations for a single atomic chain
Authors: Tewari Sumit , Bakermans Jacob , Wagner Christian , Galli Federica , van Ruitenbeek Jan M
Published: February 2019

A new way to control individual molecules and monoatomic chains is devised by preparing a human–machine augmented system in which the operator and the machine are connected by a real-time simulation. Here, a 3D motion control system is integrated with an ultra-high vacuum (UHV) low-temperature scanning tunnelling microscope (STM). Moreover, we coupled a real-time molecular dynamics (MD) simulation to the motion control system that provides a continuous visual feedback to the operator during atomic manipulation. This allows the operator to become a part of the experiment and to make any adaptable tip trajectory that could be useful for atomic manipulation in three dimensions. The strength of this system is demonstrated by preparing and lifting a monoatomic chain of gold atoms from a Au(111) surface in a well-controlled manner. We have demonstrated the existence of Fabry–Pérot-type electronic oscillations in such a monoatomic chain of gold atoms and determined its phase, which was difficult to ascertain previously. We also show here a new geometric procedure to infer the adatom positions and therefore information about the substrate atoms, which are not easily visible on clean metallic surfaces such as gold. This method enables a new controlled atom manipulation technique, which we will refer to as point contact pushing (PCP) technique.
CONSEQUENCES OF SOCIALISM IN EMPLOYEE'S ATTITUDES
Authors: Alas Ruth
Published: February 2019

This paper compares people from former socialist countries with those of non‐socialist countries according to their attitudes toward society, trade unions, work and the organisations they work for ‐ based on empirical data from 15 countries. Results indicate that intrinsic factors of job satisfaction in the traditional capitalist countries have a greater correlation with feelings toward the company and general job satisfaction than extrinsic factors. The opposite is true of former socialist countries. Countries with a socialist past have to deal with the satisfaction of needs at a lower level than traditional capitalist countries and this consequently influences attitudes and expectations toward society, trade unions, organisations and work.

Published: February 2019

Internationalization of economics has become an issue of top priority. This process enhances risks for the companies. With the formation of the European economic zone a number of suppliers has considerably grown. This environment is not friendly for developing small and medium‐size businesses because of not sufficient competitiveness of their products. Competitiveness may be achieved only if the appropriate strategies are pursued. Use of Workflow and management database systems is one of the promising strategies aimed to achieve higher efficiency. This refers both to trade and manufacture, being even more relevant for servicing enterprises. The introduction of standardized technologies can accelerate the dissemination and extension of knowledge in the future. Consistent implementation of the strategies at an enterprise means to perform the behavior oriented function. IT management model offers a possibility to pursue the strategies of getting benefits and differentiation. The emerging mixed strategy embraces both the realization of benefits achieved by Economics of Scope and differentiation benefits obtained by varying the particular products and services. A case study of the particular competitiveness strategy is provided to show how it can realize the identified features of products and services in various areas.

Published: February 2019

In order to provide Lithuanian enterprises with methodical recommendations regarding forecasting, the authors of this article have analysed the advantages and limitations of various forecasting methods. The problem of the accuracy of business forecasts is considered in greater detail, and the practical ways of doing the evaluation and assurance of the accuracy of the forecasting methods under discussion are presented here. The authors of the article suggest that an integrated forecasting model should be applied as it is much more accurate than any forecasting that is provided by the mentioned methods when taken separately. This will help to reduce the cost of forecasting, which is of utmost importance to Lithuanian businesses.

A MODEL AND METHOD FOR SOLVING A DYNAMIC TRANSPORT PROBLEM
Authors: Davulis Gediminas
Published: February 2019

The problem of optimal development of transport network is considered. We have to define a plan of network development, i.e. a network state at fixed time moments possible the scope of allocated resources such that the total expenses for reconstruction of the network and construction of its new elements as well as for passenger and cargo transportation be the lowest. Thus the problem considered can be described by the optimization model with a non‐linear non‐convex objective function and linear constraints of special structures. Since that is a non‐convex problem with a lot of extreme therefore one can expect to find only an approximate solution, close to a global one, at best. There is no effective and universal solution methods for this problem even in the sense of a local solution. This paper discusses a method for solving the problem using the synthesis of static section, that allows us to decompose dynamic problem into the set of static problems of a smaller volume, and contour optimization methods. The experimental calculation confirm that the proposed method is suitable for solving problem represented in the paper.

PROCESS MODEL FOR ORGANISATIONAL CHANGE: A STUDY OF ESTONIAN COMPANIES
Authors: Alas Ruth
Published: February 2019

Both the popular press and academic literature tend to consider organizational change as a step‐by‐step process leading to success. This paper examines the suitability of the theory that guides the implementation of change at company level for organisations in countries in transition. The author's survey, conducted in 137 Estonian companies, shows that the main focus of Estonian managers has been on initiating change and much less attention paid to assessing the process of change and making modifications and consolidating improvements. Although attention has been focused on initiating change, nobody has mentioned having identified any resistance to change. Based on the survey results the author proposes a change model for Estonian organisations.
BRAND VALUATION MODEL
Authors: Ginevičius Romualdas , Gudačiauskas Darius
Published: February 2019

Brand valuation technique is a core problem in a company value creation process. It has been done a lot of researches on the issue since brand valuation hit the headlines in 1988. The main task in brand valuation is to distinguish brand earnings from the earnings attributable to another assets: patents, intellectual property, and tangible assets. This seems to be an undisputable must, but not the only task for brand valuator. Another task is to estimate probability that the brand will generate these earnings in the future. Aim of our article is to propose brand earnings calculation, brand index calculation and brand risk assessment models, which are the results of the final doctoral dissertation. We believe that we have developed an ideal brand valuation model for emerging markets with low share liquidity.
COMPLEX EVALUATION OF THE USE OF INFORMATION TECHNOLOGIES IN THE COUNTRIES OF EASTERN AND CENTRAL EUROPE
Authors: Ginevičius Romualdas , Podvezko Valentinas
Published: February 2019

"New economy” is a specific economic phenomenon emerging when two processes including globalization and technological revolution are taking place simultaneously. A question arises what economic and institutional conditions in the states under transition would allow them to take the best advantage of the potential of “new economy”. These conditions determine if a particular state is capable of accelerating its pace of long‐term economic development and approaching the level achieved by highly‐developed countries. In this context, the problem of evaluating the readiness of the states under transition to take advantage of “new economy” acquires great theoretical and practical value. To measure the above parameter, a so‐called indicator of new economy (NEI) based on ten variables characterizing the development and effective use of “new economy” has been recently offered.

The INE indicator is a weighted sum of all ten variables for each state. It may also be calculated as a non‐weighted sum of all the related criteria.

It may be assumed (based on the expertise) that the impact of any particular variable (criterion) on the general indicator of “new economy” varies to some extent, therefore, multiple criteria decision‐making methods should be used for complex evaluation of NEI
INVESTIGATION OF SOIL POLLUTION WITH HEAVY METALS IN LITHUANIAN MILITARY GROUNDS
Authors: Vasarevičius Saulius , Greičiūte Kristina
Published: January 2019

Military grounds are the largest military activity territories in Lithuania. In some of them, military activities are going on for more than 100 years. Specific nature of long‐term activities carried out in military grounds with military equipment, weapons, ammunition and different busters have caused the anomalies of pollution with heavy metals in some places. And what is more, in many places the environment is polluted with oil products, remains of bullets and explosive devices can be found in tactical fields, and continuous devastation has resulted in a sandy soil. The damage caused to the environment by military activities is not limited with pollution of military grounds and surrounding landscapes with different chemical substances. Water that gets into the soil destroys the remains of explosives and ammunition, filters into the deeper layers of the soil and poses a risk of pollution. The surface layer of the soil is a barrier protecting subsoil water against pollution with different chemical substances. By the extent of soil pollution, it could be judged about the risk of subsoil water pollution.

The carried out investigation was aimed at finding out the distribution of heavy metals characteristic of munition (zinc, copper, lead) in the deeper layers of the soil (up to 1‐meter depth) and the trends of its changes. Tests were carried out in two major military grounds of Lithuania located in different places but used for the same purpose. The received results allowed not only to evaluate the extent of pollution with heavy metals but also to determine the peculiarities of their migration.

Both physical and dynamical properties must be considered to constrain the origins of the dynamically excited distant solar system populations. We present high-precision (g–r) colors for 25 small (H
r > 5) dynamically excited trans-Neptunian objects (TNOs) and centaurs acquired as part of the Colours of the Outer Solar System Origins Survey. We combine our data set with previously published measurements and consider a set of 229 colors of outer solar system objects on dynamically excited orbits. The overall color distribution is bimodal and can be decomposed into two distinct classes, termed gray and red, that each has a normal color distribution. The two color classes have different inclination distributions: red objects have lower inclinations than the gray ones. This trend holds for all dynamically excited TNO populations. Even in the worst-case scenario, biases in the discovery surveys cannot account for this trend; it is intrinsic to the TNO population. Considering that TNOs are the precursors of centaurs, and that their inclinations are roughly preserved as they become centaurs, our finding solves the conundrum of centaurs being the only outer solar system population identified so far to exhibit this property. The different orbital distributions of the gray and red dynamically excited TNOs provide strong evidence that their colors are due to different formation locations in a disk of planetesimals with a compositional gradient.
Discovery of a Damped Lyα System in a Low-z Galaxy Group: Possible Evidence for Gas Inflow and Nuclear Star Formation

We present a low-redshift (z = 0.029) damped Lyα (DLA) system in the spectrum of a background quasi-stellar object (QSO). The DLA is associated with an interacting galaxy pair within a galaxy group. We detected weak Lyα emission centered at the absorption trough of the DLA. The emission was likely tracing the neutral H i reservoir around the galaxies in the interacting pair, which scattered the Lyα generated by star formation within those galaxies. We also found that the interacting pair is enveloped by a large H i cloud with

Gas at similar blueshifted velocities was seen in the QSO sight line, thus suggesting the presence of a filamentary structure of the order of 100 kpc feeding the galaxy. We estimated a mass inflow rate of

Published: January 2019

We present the results of our optical (VRI) observations of the TeV blazar PG 1553+113 over eight nights in 2016 April. We monitored the blazar quasi-simultaneously in V and R bands each night and examined the light curves (LCs) for intraday flux and color variations using two of the most powerful tests: the power-enhanced F-test and the nested ANOVA test. The source was found to be significantly (>99%) variable in both V and R bands only on April 13, while clear variations only in R band LCs were seen on April 8 and 12. No temporal variation was seen in the color during the observation period. We did not find any significant correlation between V − R color index and R magnitude on any observing night. We found a mean optical spectral index of ∼0.83 ± 0.02 with a maximum variation of 0.21 by fitting a power law (F

) in the optical (VRI) spectral energy distribution of PG 1553+113. We briefly discuss the possible physical processes responsible for the observed flux and spectral variability.
Quantifying Star Formation Activity in the Inner 1 kpc of Local MIR Bright QSOs

Published: January 2019

We examine star formation activity in a distant (z < 0.1) and flux-limited sample of quasars (QSOs). Midinfrared (MIR) spectral diagnostics at high spatial resolution (∼0.4 arcsec) yield star formation rates (SFRs) in the inner regions (∼300 pc–1 kpc) for 13 of 20 of the sample members. We group these objects according to the size probed by the high angular resolution spectroscopy, with characteristic scales of <0.7 and ∼0.7–1 kpc. Using the polycyclic aromatic hydrocarbon (PAH) feature at 11.3 μm, we measure SFRs around 0.2 and 1.6 M
⊙ yr−1. We also measure the larger aperture PAH-derived SFRs in the individual IRS/Spitzer spectra of the sample and obtain a clear detection in ∼58% of them. We compare smaller and larger aperture measurements and find that they are similar, suggesting that star formation activity in these QSOs is more centrally concentrated, with the inner region (≲1 kpc) accounting for the majority of star formation measured on these scales, and that PAH molecules can be present in most local MIR-bright QSOs within a few hundred parsecs from the central engine. By comparison with merger simulations, we find that our estimation of the SFR and black hole (BH) accretion rates are consistent with a scenario in which the star formation activity is centrally peaked as predicted by simulations.
What is a Macrospicule?
Authors: Loboda Ivan P. , Bogachev Sergej A.
Published: February 2019

Macrospicules are typically described as solar jets that are larger and more long-lived than spicules, and visible mostly in transition-region spectral lines. They show a broad variation in properties, which pose substantial difficulties for their identification, modeling, and the understanding of their role in the mass and energy balance of the solar atmosphere. In this study, we focused on a subpopulation of these jets that follow parabolic trajectories when observed in the He ii 304 Å line using high-cadence observations of the Atmospheric Imaging Assembly on board the Solar Dynamics Observatory to accumulate a statistically significant sample, which included 330 such events. We found these jets to be typically narrow (3–6 Mm), collimated flows of plasma, which reach heights of about 25 Mm, thus being among the smallest jets observed in the extreme ultraviolet (EUV). Combined with the rise velocities of 70–140 km s−1 and lifetimes of around 15 minutes, this makes them plausible candidates for the EUV counterpart of type II spicules. Moreover, we have found their dynamics to be inconsistent with a purely ballistic motion; instead, there is a strong correlation between the initial velocities and decelerations of the jets, which indicates that they may be driven by magnetoacoustic shocks with a dominant period of 10 ± 2 minutes. This makes these EUV jets similar in their dynamics to conventional, or type I, spicules, thus justifying the name of macro-spicules in this case, while a substantial difference in the shock periods (1–2 minutes for the chromospheric jets) suggests a dissimilarity in the formation conditions.
Untwisting and Disintegration of a Solar Filament Associated with Photospheric Flux Cancellation

Published: February 2019

Using the high-resolution observations from the New Vacuum Solar Telescope (NVST) jointly with the Solar Dynamics Observatory data, we investigate two successive confined eruptions (Erup1 and Erup2) of a small filament in a decaying active region on 2017 November 10. During the process of Erup1, the overlying magnetic arcade is observed to inflate with the rising filament at the beginning and then stop during the explosion. In the hot EUV channel, a coronal sigmoidal structure appears during the first eruption and fades away after the second one. The untwisting rotation and disintegration of the filament in Erup2 are clearly revealed by the NVST Hα intensity data, hinting at a pre-existing twisted configuration for the filament. By tracking two rotating features in the filament, the average rotational angular velocity of the unwinding filament is found to be ∼10.°5 min−1. A total twist of ∼1.3π is estimated to be stored in the filament before the eruption, which is far below the criteria for kink instability. Several hours prior to the event, some photospheric flux activities, including the flux convergence and cancellation, are detected around the northern end of the filament, where some small-scale EUV brightenings are also captured. Moreover, strongly sheared transverse fields are found in the canceling magnetic features from the vector magnetograms. Our observational results support the flux cancellation model, in which the interaction between the converging and sheared opposite-polarity fluxes destabilizes the filament and triggers the ensuing ejection.
The Temporal Requirements of Directly Observing Self-gravitating Spiral Waves in Protoplanetary Disks with ALMA

Published: February 2019

We investigate how the detectability of signatures of self-gravity in a protoplanetary disk depends on its temporal evolution. We run a one-dimensional model for secular timescales to follow the disk mass as a function of time. We then combine this with three-dimensional global hydrodynamics simulations that employ a hybrid radiative transfer method to approximate realistic heating and cooling. We simulate ALMA continuum observations of these systems and find that structures induced by the gravitational instability (GI) are readily detectable when q = M
disk/M
* ≳ 0.25 and R
outer ≲ 100 au. The high accretion rate generated by gravito-turbulence in such a massive disk drains its mass to below the detection threshold in ∼104 years, or approximately 1% of the typical disk lifetime. Therefore, disks with spiral arms detected in ALMA dust observations, if generated by self-gravity, must either be still receiving infall to maintain a high q value, or have just emerged from their natal envelope. Detection of substructure in systems with lower q is possible, but would require a specialist integration with the most extended configuration over several days. This disfavors the possibility of GI-caused spiral structure in systems with q < 0.25 being detected in relatively short integration times, such as those found in the DSHARP ALMA survey. We find no temporal dependence of detectability on dynamical timescales.

The census of Galactic H ii regions is vastly incomplete in the southern sky. We use the Australia Telescope Compact Array to observe 4–10

radio continuum and hydrogen radio recombination line (RRL) emission from candidate H ii regions in the Galactic zone

. In this first data release, we target the brightest H ii region candidates and observe 282 fields in the direction of at least one previously known or candidate H ii region. We detect radio continuum emission and RRL emission in 275 (97.5%) and 258 (91.5%) of these fields, respectively. We catalog the ∼7 GHz radio continuum peak flux densities and positions of 80 previously known and 298 candidate H ii regions. After averaging ∼18 RRL transitions, we detect 77 RRL velocity components toward 76 previously known H ii regions and 267 RRL velocity components toward 256 H ii region candidates. The discovery of RRL emission from these nebulae increases the number of known Galactic H ii regions in the surveyed zone by 82% to 568 nebulae. In the fourth quadrant, we discover 50 RRLs with positive velocities, placing those sources outside the solar circle. Including the pilot survey, the Southern H ɪɪ Region Discovery Survey has now discovered 295 Galactic H ii regions. In the next data release, we expect to add ∼200 fainter and more distant nebulae.

Radiative lifetimes for 104 levels of Erbium (Er) i in the energy range between 31,926.003 and 44,525.705 cm−1 and 51 levels of Er ii from 31,381.779 to 47,840.962 cm−1 were measured by a time-resolved laser-induced fluorescence method. Branching fraction (BF) determinations for 356 lines from 47 out of 104 Er i levels and 122 lines related to 19 out of 51 Er ii levels were completed based on the emission spectra of hollow cathode lamps recorded using the 1.0 m Fourier transform spectrometer and are available from the digital library of National Solar Observatory on Kitt Peak, USA (http://diglib.nso.edu/). By combining these BFs and the lifetime results measured in this work, absolute transition probabilities and oscillator strengths were determined for 352 lines of Er i and 92 lines of Er ii for the first time, increasing the total number of lines with experimental transition probabilities to over 910 for Er i and over 540 for Er ii.
Time Delay between Neutrinos and Gamma-Rays in Short Gamma-Ray Bursts
Authors: Penacchioni A. V. , Civitarese O.
Published: January 2019

In this Letter we make an estimate of the time delay between signals, recorded at detectors on Earth, of neutrinos and photons originated in a short gamma-ray burst. We describe the geometry and dynamics of the system according to the Fireshell model. The delay in the photon’s arrival time is produced because the system is originally opaque to radiation; thus, the photons remain trapped and thermalize until the transparency condition is reached. We calculate the time interval between neutrino emission and photon emission in the black hole frame and transform it to the observer frame using Lorentz transformations. We obtain a difference in the arrival time at Earth of

Discrete and Continuous Ejection Models of the Radio Source Associated with GW170817
Authors: Punsly Brian
Published: February 2019

The gravity wave source, GW170817, and associated gamma-ray burst (GRB), GRB 170817A, produced radio emission that was detected in multiple epochs of Very Long Baseline Interferometry (VLBI) and with broadband radio photometry. Three unique pieces of observational evidence were determined: a discrete radio-emitting region that moves with an apparent velocity of ≈4c, a discrete region that includes all of the radio flux, and a likely synchrotron self absorption (SSA) spectral turnover on day ∼110 and day ∼160 after ejection. This unprecedented wealth of data for a GRB provides a unique opportunity to understand the radio-emitting plasma that was ejected by the putative merger event. The velocity can constrain the kinematics, and the SSA turnover has been used to constrain the size to one that is much smaller than can be done with an unresolved VLBI image, allowing one to estimate the associated plasmoid size directly from the data and improve estimates of the energetics. Models of the radio emission for both a turbulent, protonic, discrete ballistic ejection and a high dissipation region within an otherwise invisible Poynting flux dominated positron–electron jet are considered. On days ∼110 and ∼160 post-merger, for the range of models presented, the jet power is 2 × 1039–8 × 1040 erg s−1 and the ballistic plasmoid kinetic energy is 3 × 1045–1.5 × 1047 erg. Even though only valid after day 110, this independent analysis augments traditional GRB light curve studies, providing additional constraints on the merger event.

Clavicornaltica is a genus of very small flea beetles living in the leaf litter layer of Asian forests, easily sampled with Winkler extraction. The genus is presumably very rich in species, but their taxonomy is hampered by their small size and morphological uniformity.

On a ‘taxon expedition’-style field course at Kuala Belalong Field Studies Centre in Brunei Darussalam (Borneo), a new species, Clavicornalticabelalongensis n. sp., was discovered and taxonomically treated by the course participants. We also present the first DNA barcodes for the genus.
Les praticiens en Approche centrée sur la personne travaillent avec des clients et non avec des patients
Authors: Wilkins Paul , Leal Mauricio
Published: January 2019

Le terme de « client » utilisé par Rogers de préférence à celui de « patient », loin d’être anodin, témoigne d’une conception de la personne prise dans son potentiel d’évolution. Cette perspective a un impact déterminant sur la manière dont la relation thérapeutique va se constituer.
Repenser la non-directivité au regard du paradigme relationnel
Authors: Haudiquet-Lamarque Xavier
Published: January 2019

La non-directivité est bien souvent évoquée dans les cercles rogeriens, que ce soit en psychothérapie, en pédagogie, dans l’éducation ou encore à propos de la formation des futurs thérapeutes centrés sur la personne. L’auteur souhaite montrer que la notion de non-directivité est essentielle à l’épistémologie de l’Approche centrée sur la personne, même si paradoxalement elle n’a pas été développée par Carl Rogers qui l’a d’ailleurs abandonnée assez rapidement. Du coup, la non-directivité n’a jamais clairement été définie et a fait l’objet de nombreuses confusions et de déviations sémantiques, victime en outre d’une récupération politique et idéologique. Ce texte examine d’une part l’importance de ce concept pour l’Approche centrée sur la personne et les psychothérapies expérientielles (1 re partie), d’autre part les erreurs de compréhension et les difficultés d’application de la non-directivité dans certains domaines (2 e partie). Cela conduira l’auteur à tenter une nouvelle approche de la non-directivité en la situant, pour une meilleure compréhension, au sein du paradigme relationnel (3 e partie).
Napoteni delavci med kazualizacijo dela in prekarizacijo migracij
Authors: Perocco Fabio
Published: February 2019

Članek obravnava spremembe na področju dela, kazualizacije dela in prekarizacije migracij; osvetljuje tako povezave med omenjenimi pojavi kot tudi družbene posledice njihovega prepletanja, npr. dvojno prekarnost migrantskih delavcev. Preučuje tudi pomen sodobnih migracijskih politik, ki vodijo k širjenju prekarnosti in prinašajo temu primerno delavsko zakonodajo. Članek se z obravnavo evropskega konteksta na napotene delavce osredotoča kot na primer konvergence omenjenih procesov, pa tudi kot na empirični prostor družbenega raziskovanja. Ta se ukvarja z novimi oblikami prekariata in razslojenosti ter s transformacijo migracijskih politik, vedno bolj osredotočenih na začasnost in krožnost.
Pogledi izbranih avstralskih Slovencev na stanje demokratične in pravne države v Sloveniji
Authors: Valentinčič Dejan
Published: February 2019

Avtor v članku raziskuje ohranjanje vezi diasporičnih skupnosti z izvorno državo in navezanost na tamkajšnje dogajanje. Ugotavlja, da se to običajno še okrepi v kriznih in prelomnih časih. Avstralski Slovenci so se najbolj angažirali med demokratizacijskimi in osamosvojitvenimi procesi v Sloveniji, takratno dogajanje pe še vedno odzvanja pri njihovih današnjih pogledih na matično državo. V empiričnem delu članka avtor na podlagi polstrukturiranih intervjujev s skrbno izbranimi referenčnimi osebami ugotavlja, kako (izbrani) avstralski Slovenci gledajo na stanje demokratične in pravne države v Sloveniji dobrih petindvajset let po njeni osamosvojitvi in demokratizaciji.
Pomen učenja slovenščine v okviru izobraževalnega sistema za slovensko skupnost v Varaždinski županiji
Authors: Medvešek Mojca
Published: February 2019

Avtorica v svojem prispevku ugotavlja, da so se v šolskem sistemu na Hrvaškem možnosti za učenje slovenskega jezika izboljšale. Predstavlja načine poučevanja slo­venskega jezika v Varaždinski županiji, strukturo učencev, njihove motive za učenje ter odnos učencev in staršev do slovenskega jezika. Pri spraševanju o tem, v kolikšni meri učenje slovenščine v okviru izobraževalnega sistema prispeva k ohranjanju slovenske skupnosti oziroma revitalizaciji jezika, se opira na podatke, v raziskavah zbrane s pomočjo kvantitativnih in kvalitativnih metod. Pokazalo se je, da se večina mladih, ki se slovenščino uči v šoli, opredeljuje za Hrvate, njihovo vstopno znanje jezika pa je šibko.
Kakovost šole s perspektive učencev s priseljensko izkušnjo kot izhodišče za zagotavljanje inkluzivnega izobraževanja
Authors: Rutar Sonja
Published: February 2019

Avtorica v članku najprej predstavi rezultate mednarodnih primerjalnih raziskav (OECD 2015), ki kažejo, da so učni dosežki otrok priseljencev pomembno nižji od učnih dosežkov njihovih vrstnikov brez izkušnje preseljevanja. Na podlagi rezultatov ugotavlja, da je z namenom vzpostavljanja socialno kohezivne in inkluzivne družbe zagotavljanje kakovostnega pedagoškega procesa za otroke priseljencev velik pedagoški izziv. Z raziskavo v slovenskih osnovnih šolah, v katero je vključila 40 osnovnošolskih učencev s priseljensko izkušnjo, je z namenom, da bi se njihova stališča upoštevala pri oblikovanju predloga programa dela v slovenskih šolah in vrtcih, želela spoznati, kaj oni razumejo pod pojmom dobra šola.
Book Review - Natasha King, No Borders: The Politics of Immigration Control and Resistance
Authors: Mariottini Beatrice
Published: February 2019

“Imagine a society like a ripped sheet, each hole being a space of freedom destined to grow larger. As long as it is being pierced, those who find themselves caught in the material will not choke. They will be able to choose to migrate […] We need to push these walls” (anonymous interview: 159). The metaphor used by this interviewee offers a good visual explanation of the aim and direction of the No Borders movement, which Natasha King brilliantly explains in her book. The author is an English scholar with a PhD in political science from the University of Nottingham who focuses on the struggle for the freedom of movement and has conducted extensive research on the topic around Europe, specifically in Calais, France, and Athens, Greece.
Krimigracije v Sloveniji
Authors: Bajt Veronika , Frelih Mojca
Published: February 2019

Avtorici v članku obravnavata »krimigracijo« (tj. kriminalizacijo migracij) v Sloveniji. Raziskujeta elemente kriminalizacije migracij v pravnem okviru, institucijah in politikah. Uokvirjanje tematike na normativni ravni institucij analizirata skupaj s pregledom izvajanja konkretnih postopkov v praksi, analizo političnih in strokovnih mnenj pa združujeta z analizo učinkov, ki jih imajo krimigracije na migrant(k)e. Ugotavljata, da izkušnje oseb, ki migrirajo, s krimigracijskimi ukrepi potrjujejo, da migracijska politika v Sloveniji, tudi kot posledica izvajanja smernic EU, postaja strožja in vedno bolj usmerjena v povečevanje kriminalizacije migracij.
The Role of the Conditionality of EU Membership in Migrant Criminalization in the Western Balkans
Authors: Kogovšek Šalamon Neža
Published: February 2019

The EU’s responses to migration challenges exceed the territory of its memberstates. Through externalization of border control they spill over into the countries ofthe Western Balkans (WB), which is crossed by one of the most important migration routes from the Middle East and Africa to the EU. While the WB countries show indifference towards migrants and consider them an “EU problem”, the latter conditions European integration with the establishment of migration management structures similar to those in the EU. The transposition of the EU acquis also increases the criminalization of migrants, which highlights the problematic role of the EU and national legislators in WB in relation to the fundamental rights of migrants.
