Perspektivskift som nye demokratiske begyndelser
Authors: Lau Charlotte Bech , Sattrup Lise 
Published: May 2018

Artiklens ærinde er – på baggrund af to forskningsprojekter – at diskutere, hvordan aktionsforskning kan bidrage til demokratisk praksisforandring, og hvilken karakter forandringer har, når målet er demokrati. I en tid, der er kendetegnet ved store forandringer, får aktionsforskningens ønske om praksisforandring en anden karakter, hvilket peger på vigtigheden i at stoppe op og skifte perspektiv. Artiklen diskuterer, hvordan man ved at skifte perspektiv sammen med praksis kan bidrage til demokratiske praksisforandringer.
Det teoretiske afsæt er kritisk-utopisk aktionsforskning, der tager udgangspunkt i, at praksisforandringer har afsæt i hverdagslivet (bottom up). Dette kombineres med en radikal forståelse af demokrati hentet fra Rancière, som betoner, at frigørelse ikke er noget, vi kan gøre for andre, men noget, der sker ud fra en antagelse om lighed. Pointen er herved at rejse en kritik af de demokratiforståelser, der er orienterede imod at lære andre at deltage, da de bygger på en antagelse om, at nogen ikke kan deltage.
Omdrejningspunktet for diskussionen er to forskningsprojekter, hvor vi har arbejdet med henholdsvis børns deltagelse på kunstmuseer og unges deltagelse i kommunale sundhedsfremmeinitiativer. Gennem to eksempler udfolder artiklen, hvordan de metodologiske valg anvendt i de empiriske processer bidrager til at belyse og skabe demokratisk praksisforandring.
English abstract
The purpose of this article is to discuss how action research can contribute to a more democratic practice, and what the nature of the changes is when the goal is democracy. In a time characterized by many changes in society, the desire of action research for democratic changes in practice differs from the changes that tend to be implemented in practice. We argue that this points to the importance of pausing to reflect and changing perspective. The article discusses how changing perspective in practice can contribute to democratic changes.
The theoretical point of departure is Critical Utopian Action Research and democratic changes in practice based on everyday life (bottom up). This is combined with a radical concept of democracy derived from Rancière, which emphasizes that liberation is not something we can do for others, but something that happens from an assumption of equality. We wish to present a critical perspective on understandings of democracy, which are oriented towards teaching others to participate, thus assuming that some people are not able to participate.
The focal point of the discussion is two research projects investigating children’s participation at art museums and young people’s participation in municipal health promotion initiatives. Through two examples, the article unfolds how the methodological choices applied in the empirical processes contribute to the analysis and the creation of democratic changes in practice.

Pesantrens are often said to have received discriminatory treatment in Indonesian education politics, despite the fact that pesantrens have contributed positively to the development of education in Indonesia. But how is the Government's policy towards pesantren in Indonesia after Indonesia's independence? This article discusses this issue based on recent research results using a political (policy) and historical approach with descriptive methods. The technique of data collection is developed by documentation study on education policy in Indonesia, observation, as well as interviews. The study proves that the Government has dominated the policy towards pesantren where the pesantren policy is approved, accepted and implemented by government institutions. The research also concludes that since the inclusion of pesantren into By Law No. 20 Year 2003 on Indonesia’s National Education System, pesantren is in a vortex of attraction and interest between society and the Government. Pesantrens are treated discriminatively by the Government characterized by unclear implementation, regulation and budget allocation for these pesantrens. In essence, Pesantrens have not received the proper attention from the Government.

Pesantren sering dikatakan mendapatkan perlakuan diskriminatif dalam politik pendidikan Indonesia, walaupun pesantren telah berkon-tribusi positif pada perkembangan pendidikan di Indonesia. Tapi bagai-mana¬kah sebenarnya kebijakan Pemerintah terhadap pesantren di Indonesia setelah Indonesia merdeka? Artikel ini membahas isu ini ber-dasar¬kan hasil penelitian yang menggunakan pendekatan politik (kebija-kan) dan sejarah dengan metode deskriptif. Teknik Pengumpulan data dilakukan dengan studi dokumentasi terhadap kebijakan pendidikan di Indonesia, observasi, dan juga wawancara. Penelitian membuktikan bahwa Pemerintah telah mendominasi kebijakan terhadap pesantren di mana kebijakan pesantren disetujui, diterima dan dilaksanakan oleh pranata pemerintah. Penelitian menyimpulkan bahwa sejak dimasukkannya pesan¬tren ke dalam Undang-Undang Nomor 20 Tahun 2003 tentang Sistem Pendidikan Nasional, maka pesantren berada dalam pusaran tarik menarik kepentingan antara masyarakat dengan Pemerintah. Pesantren diperla¬kukan diskriminatif oleh Pemerintah ditandai dengan ketidakjelasan imple¬mentasi, regulasi dan alokasi anggaran untuk pesantren. Intinya, Pesantren belum mendapatkan perhatian yang seharusnya dari Pemerintah.

THE USE OF STAD TECHNIQUE TO IMPROVE THE STUDENTS’ READING ACHIEVEMENT AT CLASS XI IA1 OF SMAN 7 KENDARI
Authors: Tohamba Citra Prasiska Puspita 
Published: May 2018

The objective of the study is to investigate the improvement of students’ reading achievement by applying one of cooperative learning techniques namely STAD technique at class XI IA 1 of SMAN 7 Kendari. The target of this study is 70% of total students at class XI IA 1 who are expected to get 65 (based on standard of minimum score of the school). The design of this study is a Classroom Action Research (CAR) that involves four stages, namely: 1) planning, 2) action, 3) observation, 4) reflection. This study is conducted in two cycles because the target has been achieved successfully in which each cycle consists of three meetings. The research data are collected by 1) test, 2) observation sheets, and 3) field note. Based on the data in pre-observation, there were problems in students reading achievement 1) students could not find out specific information of narrative text, 2) they found difficulty to identify main idea of the text, 3) they could not determine the generic structure of narrative text correctly, (4) they did not know the meaning of the text well because they sometimes found unfamiliar words. The result of this study shows that STAD technique as cooperative learning model can improve the students’ reading achievement at class XI IA 1 of SMA Negeri 7 Kendari in academic year 2010/2011. It is reflected from the improvement of students’ score of reading test in every cycle, in which, at the first cycle, the total number of students who can get the score of ≥ 65 is 18 students or 56.3% of 32 students, with the mean score is 62.2. Moreover, after conducting the first cycle, two problems that identified in the preliminary research can be treated well in which students can find detail information from reading text and they can determine the generic structure of the narrative text. Nevertheless, the target of students’ reading achievement has not achieved yet and there are some problems that have not been treated well. Thus, this study is continued to the second cycle, where in the second cycle, the weaknesses and constraints in the first cycle are solved effectively. It can be indicated by the students’ reading improvement, in which students can get main idea of the reading text and they know how to guess the unfamiliar word. Besides, students help each other, interact, discuss with the teacher and their classmates, contribute scores for teams, give respect to others, and become independent and good students. Therefore, in the end of the second cycle, the target achievement of this study is achieved, where there are 84.4 % or 27 students of 32 students at class XI IA 1 get the score ≥ 65. In brief, STAD technique is an effective technique that can improve students’ reading achievement at class XI IA 1 of SMA Negeri 7 Kendari.
Effect of GaN substrate thickness on the optical field of InGaN lasers diodes
Authors: Martin Alfonso Juan Antonio , Sanchez M. 
Published: May 2018

In this work the influence of GaN substrate thickness on the near and far-field patterns of InGaN lasers structures is analyzed. In simulation a conventional separate confinement heterostructure of InGaN-MQW / GaN / AlGaN is considered. A fluctuating behavior is found, showing that for some values of the substrate thickness the near and far- field patterns can be optimized and there are critical values of the substrate thickness that produce the lowest values of the confinement factor and the higher values of the full wide half-maximum of the far field. It is also shown that by substituting the GaN contact layer by an AlxGa1-xN layer with a parabolic variation of the Al content it is possible to reduce the optical field leakage to substrate. Results indicated that properly choosing the thickness of the substrate and replacing the n-GaN contact layer by a graded-index (GRIN) AlxGa1-xN layer it is possible to improve both the confinement factor and Far field pattern in nitride lasers.

Fractal geometry eects in capillary imbibition process are studied. Capillary rise analysis in Koch's curve-like tubes were be carried out with iterations i = 0; 1; 2; 3; 4; 5. The behaviour was characterized in function of time, fractal geometry and height of capillary rise. An geometrical relationship for fractal dimension of ow tortuosity (dr) in porous media is obtained. The analytical model of Lucas-Washburn-Cai to describe the capillary rise by spontaneus imbibition in tubes with deterministic fractal geometry is adjusted. The equilibrium height time as function of fractal dimension of ow tortuosity in capillary tubes with tortuous path is also derived.
Solubility Enhancement of Polycyclic Aromatic Hydrocarbons by an Eco-Friendly Ester-Linked Gemini Surfactant and its Mixtures with Conventional Surfactants
Authors: Fatma Nazish , Panda Manorama , Kabir-ud-Din  
Published: May 2018

AbstractThe present study deals with the solubility enhancement of the two polycyclic aromatic hydrocarbons (PAHs) anthracene and pyrene in the aqueous micellar system of the cationic ester-containing cleavable gemini surfactant ethane-1,2-diyl-bis(N,N-dimethyl-N-tetradecylammoniumacetoxy) dichloride (14-E2-14 = C14H29(CH3)2N+(CH2COOCH2)2N+(CH3)2C14H29 · 2Cl−)), and its equimolar binary mixtures with some typical conventional cationic, anionic and non-ionic surfactants. The surface tension and conductivity measurements were used to evaluate the physicochemical parameters such as the critical micelle concentration (CMC), the interaction parameter (βm) and Gibbs excess free energy of micellization (ΔGexm) of the systems. The extent of solubilization of the micellar systems towards PAHs has been quantified in terms of molar solublization ratio (MSR), micellar/water partition coefficient (ln Km) and the standard Gibbs free energy of solubilization (ΔGs0). Above the CMC, all studied single as well as binary gemini-conventional surfactant systems show an increase in solubilization of the PAHs. For pure systems, the MSR value of Brij 58 was found to be significantly higher than that of the other amphiphiles. Amongst the mixed surfactant systems, the solubility enhancement of anthracene is found to be maximum in the 14-E2-14 + SDS/SDBS system whereas the system14-E2-14 + Brij 58 shows a higher solubility for pyrene.
Novel Carbohydrate Based Non-Ionic Gemini Surfactants with Flexible Spacer as Reverse Micellar Systems for Encapsulation of D- and L-Enantiomers of Some Aromatic α-Amino Acids in n-Hexane
Authors: Singh Nirmal , Sharma Lalit 
Published: May 2018

AbstractNovel non-ionic gemini surfactants derived from carbohydrate carrying two hydrophobic tails with varying tail length of C12, C14 and C16, two sugar moiety as head groups, and an α-(CH2)6-flexible spacer have been synthesized. The head group of these gemini surfactants consists of sugar moiety connected to C-6 of tertiary amines. These gemini amphiphiles were explored as reverse micellar systems for encapsulation of some D- and L-enantiomers of aromatic α-amino acids i.e. histidine (His), phenylalanine (Phe), tyrosine (Tyr) and tryptophan (Trp) in n-hexane in the absence of water. It is found that these amino acids are encapsulated in the order of His > Phe > Tyr > Trp, and it is also observed that in almost all cases the D-enantiomers were better encapsulated as compared to the L-enantiomers. In all cases, encapsulation of D- and L-enantiomers of aromatic α-amino acids increased with increase of the hydrophobic chain length of the gemini surfactants.
Improved Synthesis and Properties of N-(3-octadecylamino-2-hydroxyl) Propyl Trimethyl Ammonium Chloride
Authors: Cheng Huiyun , Xu Hujun , Liu Fan , Chen Xiuying 
Published: May 2018

AbstractThe cationic surfactant, N-(3-octadecylamino-2-hydroxyl) propyl trimethyl ammonium chloride was synthesized by an improved synthesis method and the structure was confirmed by Mass Spectrometry and 1H NMR Spectrometry. The physiochemical properties of the product were investigated systematically by surface tension and conductivity measurements. Various physiochemical parameters were calculated to evaluate the surface activities of the surfactant. The results show that both the critical micelle concentration and the degree of counterion dissociation increased with increasing temperature, but the surface tension at CMC decreased, which is opposite to that obtained on the previous condition with increasing NaCl concentration. The thermodynamic parameters obtained from conductivity measurement show that the micelle formation of the surfactant is entropy-driven in the investigated temperature range. While used as an asphalt emulsifier, N-(3-octadecylamino-2-hydroxyl) propyl trimethyl ammonium chloride exhibited an excellent emulsifying ability and it was a medium-set asphalt emulsifier.
A General Method for Assessing the Origin of Interstellar Small Bodies: The Case of 1I/2017 U1 (‘Oumuamua)
Authors: Zuluaga Jorge I. , Sánchez-Hernández Oscar , Sucerquia Mario , Ferrín Ignacio 
Published: May 2018

Abstract
With the advent of more and deeper sky surveys, the discovery of interstellar small objects entering into the solar system has been finally possible. In 2017 October 19, using observations of the Pan-STARRS survey, a fast moving object, now officially named 1I/2017 U1 (‘Oumuamua), was discovered in a heliocentric unbound trajectory, suggesting an interstellar origin. Assessing the provenance of interstellar small objects is key for understanding their distribution, spatial density, and the processes responsible for their ejection from planetary systems. However, their peculiar trajectories place a limit on the number of observations available to determine a precise orbit. As a result, when its position is propagated ∼105–106 years backward in time, small errors in orbital elements become large uncertainties in position in the interstellar space. In this paper we present a general method for assigning probabilities to nearby stars of being the parent system of an observed interstellar object. We describe the method in detail and apply it for assessing the origin of ‘Oumuamua. A preliminary list of potential progenitors and their corresponding probabilities is provided. In the future, when further information about the object and/or the nearby stars be refined, the probabilities computed with our method can be updated. We provide all the data and codes we developed for this purpose in the form of an open source C/C++/Python package, iWander, which is publicly available at http://github.com/seap-udea/iWander.

Published: May 2018

Abstract
The results of speckle interferometric observations at the 4.1 m Southern Astrophysical Research Telescope in 2016 and 2017 are given, totaling 2483 measurements of 1570 resolved pairs and 609 non-resolutions. We describe briefly recent changes in the instrument and observing method and quantify the accuracy of the pixel scale and position angle calibration. Comments are given on 44 pairs resolved here for the first time. The orbital motion of the newly resolved subsystem BU 83 Aa,Ab roughly agrees with its 36-year astrometric orbit proposed by J. Dommanget. Most Tycho binaries examined here turned out to be spurious.

Abstract
We characterize the environments of local accreting supermassive black holes by measuring the clustering of AGNs in the Swift/BAT Spectroscopic Survey (BASS). With 548 AGN in the redshift range 0.01 < z < 0.1 over the full sky from the DR1 catalog, BASS provides the largest, least biased sample of local AGNs to date due to its hard X-ray selection (14–195 keV) and rich multiwavelength/ancillary data. By measuring the projected cross-correlation function between the AGN and 2MASS galaxies, and interpreting it via halo occupation distribution and subhalo-based models, we constrain the occupation statistics of the full sample, as well as in bins of absorbing column density and black hole mass. We find that AGNs tend to reside in galaxy group environments, in agreement with previous studies of AGNs throughout a large range of luminosity and redshift, and that on average they occupy their dark matter halos similar to inactive galaxies of comparable stellar mass. We also find evidence that obscured AGNs tend to reside in denser environments than unobscured AGNs, even when samples were matched in luminosity, redshift, stellar mass, and Eddington ratio. We show that this can be explained either by significantly different halo occupation distributions or statistically different host halo assembly histories. Lastly, we see that massive black holes are slightly more likely to reside in central galaxies than black holes of smaller mass.
Eta Carinae’s Declining Outflow Seen in the UV, 2002–2015*

Published: May 2018

Abstract
Existing Hubble Space Telescope UV data offer many previously neglected clues to η Car’s behavior since 2000. Here we examine a subset of observations with diverse results. (1) The star’s rapid change of state is confirmed by major changes in UV absorption lines, circumstellar extinction, and other features. (2) N iii] λ1750 is one of the two most luminous emission features in η Car’s observable spectrum, comparable to Hα. This and other semi-forbidden lines are useful because they have no P Cyg absorption. (3) N iii] multiplet ratios provide the first direct diagnostic of gas densities in η Car’s outflow. They strongly suggest that high-excitation lines originate in condensations within the colliding-wind shocked region. The parameters imply that published models have not adequately represented the essential small size scales. (4) In 2002–2004, a very large amount of N iii] emission had anomalous Doppler velocities from +400 to +1200 km s−1. This is a mystery; we conjecture that it may have resulted from a burst of mass ejection in the 2003.5 periastron event. Various other effects are also difficult to explain and merit further investigation.
