Published: February 2017

AbstractThe paper presents statistics of the asteroids observed and discovered at the Molėtai Observatory, Lithuania, in 2005–2007 within the project for astrometric observations of the near-Earth objects (NEOs), the main belt asteroids and comets. CCD observations of asteroids were obtained with the 35/51 cm Maksutov-type meniscus telescope and the 1.65 m Ritchey-Chretien reflector. In the Minor Planet Circulars and the Minor Planet Electronic Circulars (2005–2007) we published 17 003 astrometric positions of 2980 asteroids. Among them 112 were new normal asteroids and one NEO (2006 SF77) discovered at Molėtai; a few NEOs were found by our team independently. For the asteroids discovered at Molėtai their precise orbits were calculated. Because of short observational arc, a few asteroids have low-precision orbits and some asteroids have been lost. For three of them with low-precision orbital elements (NEO 2006 SF77 and two Mars crossers – 2006 SN368 and 2007 VM315), we present their ephemerides for 2016–2018.
Improvements on a Unified Dark Matter Model

Published: February 2017

AbstractWe study, by means of a spherical collapse model, the effect of shear, rotation, and baryons on a generalized Chaplygin gas (gCg) dominated universe. We show that shear, rotation, and the presence of baryons slow down the collapse compared to the simple spherical collapse model. The slowing down in the growth of density perturbation is able to solve the instability of the unified dark matter (UDM) models described in previous papers (e.g.
Comment on “The Psychology of Creativity: A Critical Reading” by Vlad Petre Glăveanu
Authors: Hennessey Beth A. 
Published: February 2017

Abstract
In this commentary, I applaud Glăveanu’s attempts to shake things up and introduce some much-needed disruption into the study of creativity. Glăveanu is a “ big thinker” and he is correct to worry about the growing fragmentation of the field. I share his concern that the so-called “ social psychology of creativity” really isn’t all that social. Most researchers and theorists continue to decontextualize creativity, giving little attention to the cultural and environmental factors that contribute to creativity of performance. Yet Glăveanu also presents some arguments with which I disagree. Most striking is his apparent misunderstanding of the purpose and functioning of the Consensual Assessment Technique (CAT). In addition, I am less surprised than is Glăveanu about the current state of our field. The same narrowing of research questions plagues every branch of the study of psychology. However, the tides may be changing. At the forefront of a reform movement are a number of creativity theorists and journal editors. My own hope is that as researchers are given license to expand their work to include a wide variety of experimental designs, methodologies and contexts, they will adopt as their core mission the promotion of the growth of creativity at the individual, group, societal and multi-cultural levels.
Imagineering: Re-Creating Spaces through Collaborative Art-Making
Authors: Trowsdale Jo 
Published: February 2017

Abstract
This paper considers the significance of the types of learning relationships developed between children and adults during a creative arts and engineering project: The Imagineerium. It focuses on data collected through observations, 18 interviews conducted during and six weeks after the pupils had been involved in the project, and 25 interviews conducted one year later. This is supported by reference to a wider data set gathered from questionnaires, field notes and journal analysis conducted with 72 pupils. A significant and recurring feature emerging from this data was pupils’ perception of the positive relationships they experienced within The Imagineerium project. The article considers the elements of the project that contribute to this relational experience. In particular, it argues the importance of this educational experience being located within a tradition of community arts, within the practice of art-making and involving adult facilitators committed to these practices.
New Digital Media and Flow: A Study of Experience
Authors: Gruner Daniel T. 
Published: February 2017

Abstract
The burgeoning use of new digital media (NDM) platforms for social networking such as Facebook, Twitter, and Instagram has consistently been associated with out-group prejudice, less prosocial behaviour, less fulfilling friendships, and lower levels of moral reflection, integrity, and subjective well-being. But the context of NDM use is often neglected when examining its psychological effects. Moreover, such studies are limited to retrospective accounts and can benefit from examining episodic experiences of flow, boredom, apathy, and anxiety. Drawing on data collected using the Experience Sampling Method (ESM), this study assessed the psychological impact of social networking on low and high media users. Participants (N = 65) were signaled six times per day for seven days and asked to respond to brief surveys about subjective momentary experiences. Findings indicated that high media users, on average, reported less positive moods, and also reported being significantly less creative and less energetic each day. Further, high media users reported deriving less meaning from daily activities, and were marginally less satisfied with the overall quality of their week than their low media user counterparts. When comparing all media users across flow quadrants, creativity, meaning, engagement, and energy levels were highest in flow, and substantially decreased across the remaining quadrants. Notably, self reported mood was slightly higher during instances of boredom than flow. However, a more nuanced comparison of these outcomes revealed that high media users reported being marginally more creative and engaged during boredom, thereby identifying differences in how the two groups approached social media.

AbstractForecasting of inventory is an enigma to various firms at different echelon levels of supply chain. Abnormality in forecasting an inventory may leads to fluctuations in upstream supply chain. On upswing it can be uneconomical in terms of stock-out cost, while on the down trend it can be expensive in terms of stock holding costs. To amend the firms efficiency, in this paper the model developed by (Akhtar Tanveer et al. An Optimization model for Mitigating Bullwhip-Effect in a Two-Echelon Supply chain. Int conf Traf Transp Stud 2014;138:289-97) is successfully applied to steel processing firm to mitigate the Bull-whip or Whip-lash effect in the supply chain. The objective function is to minimize the variation between the actual order quantity and demand forecast of multiple products at various echelons and the simple exponential smoothing is compiled to forecast the demand of products. The model is furthermore validated by an illustration of seven products and it depicts that the model emanates an optimal set of smoothing parameters to attenuate the whip-lash effect.
Early and Late Loss of the Cytoskeletal Scaffolding Protein, Ankyrin G Reveals Its Role in Maturation and Maintenance of Nodes of Ranvier in Myelinated Axons

Published: February 2017

The mechanisms that govern node of Ranvier organization, stability, and long-term maintenance remain to be fully elucidated. One of the molecular components of the node is the cytoskeletal scaffolding protein, ankyrin G (AnkG), which interacts with multiple members of the nodal complex. The role of AnkG in nodal organization and maintenance is still not clearly defined as to whether AnkG functions as an initial nodal organizer or whether it functions as a nodal stabilizer after the nodal complex has been assembled. Using a mouse model system, we report here that perinatal and juvenile neuronal ablation of AnkG has differential consequences on nodal stability. Early loss of AnkG creates immature nodes with abnormal morphology, which undergo accelerated destabilization within a month, resulting in rapid voltage-gated sodium (NaV) channel and βIV spectrin loss with reduced effects on neurofascin 186. On the other hand, late ablation of AnkG from established nodal complexes leads to slow but progressive nodal destabilization over 10 months, primarily affecting βIV spectrin, followed by NaVchannels, with modest impact on neurofascin 186. We also show that ankyrin R and βI spectrin are not sufficient to prevent nodal disorganization after AnkG ablation. Additionally, nodal disorganization in both early and late AnkG mutants is accompanied by axonal pathology and neurological dysfunction. Together, our results suggest that AnkG plays an indispensable role in the maturation and long-term stabilization of the newly assembled nodal complex, and that loss of AnkG after nodal stabilization does not lead to rapid nodal disassembly but to loss of specific nodal components in a time-dependent manner.SIGNIFICANCE STATEMENTNodes of Ranvier are the myelin-free gaps along myelinated axons that allow fast communication between neurons and their target cells by propagating action potentials in a saltatory manner. The cytoskeletal scaffolding protein ankyrin G (AnkG) has been thought to play an important role in node formation; however, its precise role in nodal assembly, stability, and maintenance is still not clear. By using spatiotemporal ablation of AnkG, we report its differential role in nodal maturation and stabilization. We show that early AnkG-deficient nodes fail to mature and undergo rapid destabilization. In contrast, nodes that assemble with AnkG are much more stable and undergo gradual disintegration with sequential loss of nodal components in the absence of AnkG.
DNA Repair inDrosophila: Mutagens, Models, and Missing Genes
Authors: Sekelsky Jeff 
Published: February 2017

AbstractThe numerous processes that damage DNA are counterbalanced by a complex network of repair pathways that, collectively, can mend diverse types of damage. Insights into these pathways have come from studies in many different organisms, including Drosophila melanogaster. Indeed, the first ideas about chromosome and gene repair grew out of Drosophila research on the properties of mutations produced by ionizing radiation and mustard gas. Numerous methods have been developed to take advantage of Drosophila genetic tools to elucidate repair processes in whole animals, organs, tissues, and cells. These studies have led to the discovery of key DNA repair pathways, including synthesis-dependent strand annealing, and DNA polymerase theta-mediated end joining. Drosophila appear to utilize other major repair pathways as well, such as base excision repair, nucleotide excision repair, mismatch repair, and interstrand crosslink repair. In a surprising number of cases, however, DNA repair genes whose products play important roles in these pathways in other organisms are missing from the Drosophila genome, raising interesting questions for continued investigations.

Penelitian ini dilakukan dengan metode survei dengan cara mencari lokasi-lokasi ada aktivitas penangkapan ikan, wawancara dengan nelayan, dan bekerjasama dengan enumerator dalam mengumpulkan data penelitian. Hasil penelitian telah mendapatkan 22 jenis ikan endemik dan 6 jenis ikan introduksi yang tertangkap di ketiga danau (Matano, Mahalona, dan Towuti). Danau Matano tertangkap 7 jenis ikan endemik, Mahalona 8 jenis, dan Danau Towuti tertangkap 15 jenis. Jaring dan bagan merupakan alat tangkap yang dominan digunakan oleh nelayan untuk menangkap ikan endemik seperti ikan buttini (Glossogobius sp.) dan pangkilan (Telmatherina sp. dan Paratherina sp.). Hasil tangkapan ikan di Danau Towuti 5,7 kg per ha per tahun, Danau Mahalona 1,8 kg per ha per tahun, dan Danau Matano 1,2 kg per ha per tahun. Untuk melestarikan ikan-ikan endemik perlu ada pengelolaan dan pengaturan waktu dan lokasi penangkapan yang baik. A research in order to identify the capture fishery at Lakes: Matano, Mahalona, and Towuti was conducted from May to December 2005. Lakes Matano, Mahalona, and Towuti are examples of the representative tectonic lake ecosystems housing the endemic and some exotics (tilapia and carp, Cyprinus carpio) fish species. The survey methods were used in this reseacrh by hunting the location of fishing activities, interview with fishermen and partnership with enumerator in collecting research data. Results of the research show that 23 endemic fish species and 6 introduced per exotic fish species were caught in three research lakes. From 22 endemic fishes, 7 fish species were caught at Lake Matano, 8 fish species at Lake Mahalona, and 15 fish species were caught at Lake Towuti respectively. Gillnets and bagan were dominant fishing gears to catch the endemic fishes such as buttini (Glossogobius sp.) and pangkilan (Telmatherina sp. and Paratherina sp.). The productivity of the fisheries were 5.7 kg per ha per year for Lake Towuti, 1.8 kg per ha per year (Lake Mahalona), and 1.2 kg per ha per year (Lake Matano) respectively. To sustain endemic fishes is needed a better management eg. domesticating and regulating time and location of capture endemic fish species.

Penelitian ini bertujuan untuk mempelajari pola agregasi ikan di bawah pengaruh cahaya lampu bagan tancap. Penelitian dilaksanakan pada bulan Mei 2005 di Kepulauan Seribu. Pengamatan pola agregasi ikan dilakukan dengan menggunakan alat akustik Simrad EY500. Data intensitas cahaya diambil dengan menggunakan light meter LI-250, serta verifikasi hasil tangkapan untuk memperkuat hasil analisis. Analisis meliputi interpretasi visual berbasis pada presentasi grafik yang merupakan dasar bagi penafsiran data dan penyusunan informasi. Pengaruh intensitas cahaya yang berbeda terhadap agregasi ikan mempunyai pola yang tidak sama, baik nilai intensitas cahaya optimumnya, besarnya agregasi, maupun posisi kedalaman untuk nilai agregasi terbesar. Proses pengumpulan ikan pada awal penyinaran dengan perlakuan jenis lampu petromak lebih cepat dibanding dengan hasil perlakuan lampu mercuri. Ikan akan beradaptasi terhadap variasi iluminasi cahaya sehingga selama proses pencahayaan terjadi migrasi.

Molecular dynamics is a popular method to observe the movement of interacting molecules. In this study molecular dynamics method was used to observe the phenomenon of iron corrosion and analyze effect of noble gases as a corrosion inhibitor for iron in liquid metal PbBi. Physical quantities are evaluated from the results of this study including: Mean Square Displacement (MSD), the diffusion coefficient, and for the crystal structure is visualized using Ovito program. The ron is placed in the middle high temperature liquid PbBi, the noble gases is injected into the liquid metal. Based on the three kinds of the noble gases (helium, neon, and argon) thhat injected into the molten metal PbBi, it obtained that Argon is the most effective in inhibiting the corrosion of iron. Argon is able to reduce the corrosion rate of 80.29% iron for temperature of 1023K. One reason to use the noble gas because these gases are difficult to react with other elements.

Core IdeasSoil solution sampling is essential to better understand water and solute movement in soils.A review of different types of soil solution samplers is provided in this paper, including: drainage lysimeter or soil column, pan lysimeter, resin bags or membranes, wick lysimeters, suction cup, and suction plate.Recent developments, modifications, and recommendation criteria are provided for selecting appropriate soil solution extraction samplers.A number of contaminants including agrochemicals (fertilizers, pesticides), heavy metals, trace elements, and pathogenic microbes along with pharmaceuticals and hormones used in animal production move through the soil and are responsible for degradation of groundwater quality. Therefore, it is essential to sample soil solution for better understanding of movement and environmental fate of various contaminants in soils. We review different soil solution extraction samplers. The soil solution samplers discussed here are: drainage lysimeter or soil column, pan lysimeter, resin bags or membranes, wick lysimeters, suction cup, and suction plate. We have reviewed 304 journal articles representing a wide array of scientific disciplines. A brief history of soil solution monitoring and terminology used for describing various soil solution samplers is also provided. This review classifies literature on the basis of type of soil solution extraction samplers, soil type, land use–land cover (LULC), and analytes measured. Recommendation criteria are provided for selecting appropriate soil solution extraction samplers based on spatial and temporal variation, cost, soil type, amount of disturbance caused during installation of soil solution samplers, and monitoring of leachates involving different cations, anions, carbon, pH, EC, colloids, pesticides, and microbes. Use of advanced techniques with lysimeters for monitoring soil moisture content, soil water potential and flux is also discussed in this review.
