A Computational Model of Learning to Count in a Multimodal,Interactive Environment
When learning to count, children actively engage with a varietyof counting tasks and observe demonstrations by more knowl-edgeable others. We investigate how a single neural network-based agent, situated in a multimodal learning environment,can learn from observing such demonstrations to perform mul-tiple number tasks such as counting temporally and spatiallydistributed objects, and a variant of the give-N task. We findthat i. the agent can learn different tasks that require counting,ii. learning progresses in similar stages for different tasks, iii.sequential learning of subtasks aids learning of the full task ofcounting spatially distributed objects, and iv. a mechanism forupdating memory when each object is counted emerges fromlearning the task. The work relies on generic deep learningprocesses in widely used neural network modules rather thanmechanisms specialized for mathematics learning, and pro-vides an architecture in which aspects of a sense of numberemerge from learning several different number related tasks
PENERAPAN SISTEM INFORMASI MANAJEMEN PELATIHAN "WELL CONTROL IADC WELL CAPWORKOVER COMPLETION" DI PUSAT PENGEMBANGAN SUMBER DAYA MANUSIA MINYAK DAN GAS BUMI CEPU
Tujuan dari penelitian ini adalah untuk mengetahui prosedur pengarsipan dokumen pelatihan, serta untuk menganalisa permasalahan mengenai keterlambatan pengarsipan atau upload dokumen pelatihan yang berkenaan dengan Sistem Informasi Manajemen berbasis komputer yang ada pada PPSDM MIGAS Cepu. Teknik pembahasan yang akan digunakan dalam penelitian ini adalah dengan menggunakan metode Deskriptif yang jenis datanya dibagi menjadi dua yakni, Data Primer didapatkan menggunakan metode pengumpulan data wawancara dengan lima orang staf PPSDM MIGAS Cepu. Sementara Data Sekunder didapatkan dengan memeriksa data atau dokumen dari perusahaan berupa tabel rekapitulasi perkembangan upload dokumen pelatihan “Well Control IADC Well Capworkover Completion” yang dilaksanakan pada Januari 2017. Pengarsipan dan upload dokumen pelatihan kedalam Sistem Informasi Diklat (SID) pada PPSDM MIGAS Cepu telah diatur dan dilaksanakan sesuai dengan Standar Operasional Prosedur (SOP) oleh para staf. Namun masih ada dokumen yang terlambat atau memakan waktu lama untuk diarsipkan kedalam SID. Komputer atau scanner yang rusak, menunggu pengesahan dari kepala sub bagian terkait hingga ada yang menyebutkan bahwa mereka tidak terlambat dan masih dalam batas waktu pengarsipan menjadi alasan dari para staf. Akan tetapi masalah utama dari terlambatnya pengarsipan adalah tidak adanya tenggang waktu dalam SOP untuk mengunggah dokumen pelatihan kedalam SID. Kurang tegasnya SOP mengenai batas waktu untuk mengunggah dokumen menjadi penyebab terlambatnya upload dokumen kedalam SID dan menjadi penyebab menimbulkan bermacam-macam alasan staf mengenai adanya dokumen yang memakan waktu lama untuk diunggah kedalam SID. Manajemen perlu mengevaluasi SOP pengarsipan dokumen pelatihan dan mempertegas batas waktunya agar para staf dapat lebih disiplin dan tidak ada lagi dokumen yang terlambat atau bahkan memakan waktu lama untuk diunggah kedalam Sistem Informasi Diklat.

The Electrochemistry of Simple Inorganic Molecules in Room Temperature Ionic Liquids
The electrochemistry of simple inorganic compounds in room temperature ionic liquids (RTILs) is reviewed and some new work in this area is presented. This paper focuses on the comparison between electrochemical behaviour in RTILs and in conventional aprotic solvents. Some compounds (iodides, O2, NO2, SO2, NH3) display similar reactions and mechanisms in RTILs as in aprotic solvents (as is observed for organic compounds). However other species (nitrates, PCl3, POCl3) show remarkably different behaviour to traditional solvents. This makes RTILs very promising media for the study of inorganic compounds, and highlights the need for more investigations in this exciting area
Vertical Distribution of Hard Corals in Southern Siladen Island
This study was aimed at provide information on hard coral distribution in southern Siladen Island. The work was done using SCUBA gear Line Intercept Transect (LIT). Thirty m long-line transects were placed at the reef flat, 5 m depth, 10 m depth, 15 m depth, and 20 m depth. A total of 44 hard coral genera was recorded, and the highest number of genre was found at 5 m depth. Coral species diversity was also high enough at the reef flat (1.032) and 5 m depth (1.28). Coral reef condition at 10 m depth was good enough as well and categorized as productive due to much higher percent of the biotic component than the abiotic component. The dominant life forms consisted of tabulate Acropora and branching corals at the reef flat, encrusting corals, branching corals, and foliose corals at 5 m, encrusting corals at 10 and 20 m depth, and massive corals, encrusting corals, and branching corals at 15 m depth, respectively

Electrochemical Oxidation and Sensing of Methylamine Gas in Room Temperature Ionic Liquids
The electrochemical behaviour of methylamine gas in several room temperature ionic liquids (RTILs), [C2mim][NTf2], [C4mim][NTf2], [C6mim][FAP], [C4mpyrr][NTf2], [C4mim][BF4], and [C4mim][PF6] has been investigated on a Pt microelectrode using cyclic voltammetry. A broad oxidation wave at approximately 3 V, two reduction peaks and another oxidation peak was observed. A complicated mechanism is predicted based on the voltammetry obtained, with ammonia gas as a likely by-product. The currents obtained suggest that methylamine has a high solubility in RTILs, which is important for gas sensing applications. The analytical utility of methylamine was then studied in [C4mpyrr][NTf2] and [C2mim][NTf2]. A linear calibration graph with an R2 value of 0.99 and limits of detection of 33 and 34 ppm were obtained respectively, suggesting that RTILs are favourable non-volatile solvents for the electrochemical detection of highly toxic methylamine gas

Implementing an integrated approach to self-management support in an acute major trauma therapy team: an improvement project.
More patients now survive multiple trauma injuries, but the level of long-term unmet needs is high. Evidence shows self-management support can improve patients ' confidence to manage these needs but traditionally this support starts post-hospital. Starting self-management support early could prepare patients and families for successful transitions from hospital. The skills and commitment of clinicians have been shown to contribute to the success or failure of self-management approaches. The aim of this project was to explore the feasibility of integrating self-management support in an acute major trauma setting by evaluating the impact of an educational intervention on clinicians' knowledge, attitudes and behaviours regarding self-management support and identifying any barriers and facilitators to integrating self-management into daily practice. Two improvement cycles were carried out over a 1-year period involving 18 allied health professionals (AHPs) in an acute major trauma centre in London, UK. An educational intervention, 'Bridges Self-Management Programme' was modified for the setting. The impact was evaluated using (1) a clinician questionnaire to evaluate knowledge and attitudes; (2) case reflection forms and (3) peer review to observe interactions to integrate self-management support. Questionnaire data were summarised and pre-training and post-training scores compared; the qualitative data from written case reflections, verbal and written feedback from training and group discussions was described and analysed thematically. The result of two improvement cycles has shown it was feasible to improve AHP's knowledge, attitudes and change behaviours regarding self-management support in the acute trauma setting, but difficult to sustain change beyond 6 months. Key barriers such as the pressure to discharge patients and support within the wider multidisciplinary team (MDT) were identified. Facilitators included the introduction of a new key-worker, to enable shared team approaches and paperwork to involve patients and families in goal setting and treatment planning. The main learning was to ensure sustainability mechanisms from the outset, engage the wider MDT in training, and integrate self-management language and principles into team processes
Community Structure of Ascidian in Mike’s Point Bunaken Waters, Manado City, North Sulawesi Province
Ascidians are marine invertebrates that have been classified with the subphylum Urochordata (Tunicata). These organisms are very important because they contribute a lot to the stability of the marine ecosystem. This study aims to determine the species composition, density, ecological index (diversity, uniformity, dominance), distribution patterns, and substrate occupied by Ascidian. Data were collected at Mike’s Point Bunaken waters at two depths 7 m and 14 m. The method used a direct observation along the 50 m and 2 m width belt transect. In this study, the transect was applied parallel to the coastline at each depth, where 3 replications were performed. The results show 26 species consisting of 13 species at a depth of 7 m and 22 species at a depth of 14 m were identified. The average density of each species was 0.05 ind/m2 at both depths. Diversity Index of 1.76 at 7 m depth and 2.24 at 14 m depth was determined. Uniformity Index was 0.68 at 7 m depth and 0.73 at 14 m depth. Dominant Index of 0.67 at 7 m depth and 0.88 at 14 m depth was also determined. The distribution pattern of species was dominated by uniform distribution, and the substrate most commonly occupied by Ascidianns was dead coral overgrown with algae.Keywords: Ascidian, composition and density, ecological index, distribution pattern, substrate AbstrakAscidian adalah Avertebrata laut yang termasuk dalam subfilum Urochordata (Tunicata).

Electrochemical Behavior of Chlorine on Platinum Microdisk and Screen-Printed Electrodes in a Room Temperature Ionic Liquid
As a result of the toxic and corrosive nature of chlorine gas, simple methods for its detection are required for monitoring and control purposes. In this paper, the electrochemical behavior of chlorine on platinum working electrodes in the room temperature ionic liquid (RTIL) 1-ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide ([C2mim][NTf2]) is reported, as a basis for simple sensor devices. Cyclic voltammetry (CV) and chronoamperometry (CA) on a Pt microelectrode revealed the two-electron reduction of Cl2 to chloride ions. On the CV reverse sweep, an oxidation peak due to the oxidation of chloride was observed. The reduction process was diffusion controlled at the concentrations studied (≤4.5% in the gas phase), in contrast to a previous report (J. Phys. Chem. C2008, 112, 19477), which examined only 100% chlorine. The diffusion-controlled currents were linear with gas-phase concentration. Fitting of the CA transients to the Shoup and Szabo expression gave a diffusion coefficient for chlorine in the RTIL of ca. 2.6 × 10–10 m2 s–1. Furthermore, determination of the equilibrium concentration of Cl2 in the RTIL phase as a function of gas-phase concentration enabled a value of 35 to be determined for the Henry’s law dimensionless volatility constant. The electrochemical behavior of chlorine on a Pt screen-printed electrode was also investigated, suggesting that these devices may be useful for chlorine detection in conjunction with suitable RTILs
