Predicting Eye Movement and Fixation Patterns on Scenic Images Using Machine Learning for Children with Autism Spectrum Disorder

This study uses eye-tracking experiment data to predict the fixation points for children with Autism Spectrum Disorder (ASD) and Typically Developing (TD) for 14 ASD and 14 TD subjects for 300 scenic images. Based on explanatory Logistic Regression models, it is evident that fixation patterns for both ASD and TD subjects focus near the center of each scenic image. Using gradient boosting the researchers successfully identify 31.7% and 39.5% of all fixation points in the top decile of predicted fixation points for ASD and TD subjects respectively. Results conclude that TD subjects have less variability in their eye movement and fixation points leading to increased accuracy in predicting where they will look

The Effects of Aluminum Ion Exposure on Planarian Photophobic Response to Different Wavelengths of Light

Aluminum exposure has been linked to the development of neurological diseases (Kim et al., 2021). It has increased in quantity in the environment due to industrial activity in producing personal care products and fast food (Tietz et al., 2019). The freshwater invertebrate planarian flatworm Giardia dorotocephala (G. dorotocephala) serves as a model organism. Humans and planarians both express the ion channel transient receptor potential ankyrin 1 (TRPA1), which is responsible for thermotaxis, locomotive response to heat, and pain reception (Arenas et al., 2017). Aluminum exposure can exert ion channel-related toxicity via the TRPA1 protein. It has been found that planarian TRPA1 activates when exposed to light. The planarians have a photophobic reaction to light sources, meaning that when exposed to a light source they will instinctually swim away and towards the darkest area they can reach. This experiment addresses the question of what effect aluminum has on planarian photophobic behavior. We hypothesize that aluminum ion exposure increases photophobic behavior in planarians. The study was split into different parts that built off each other. First, planarians were exposed to various concentrations to determine their aluminum to reference dosage. It was determined that 300 mg/L aluminum was the highest dosage without acute behavioral toxicity. Next, we observed their reaction to different wavelengths of light to observe natural photophobic behavior in G. dorotocephala. The results suggest that all light sources garnered a photophobic response, while the no light control did not. The next experiment co-exposed the planarians to 300 mg/L aluminum and different wavelengths of light. It was found that white exposure did not elicit photophobic behavior, while UV light did cause photophobia, though this was dependent on the duration of aluminum exposure. To observe the planarians\u27 behavior to light when TRPA is modulated, they were exposed to HC-030031 dissolved in DMSO and DMSO alone. For both white and UV light, there was a steady decrease in their photophobic behavior. Taken together these results suggest that aluminum does not amplify their photophobic behavior. We suggest aluminum may instead inhibit planarian motility

PENGARUH DEBT DEFAULT DAN FINANCIAL DISTRESS TERHADAP OPINI AUDIT GOING CONCERN (Studi Empiris Pada Perusahaan Manufaktur Yang Terdaftar di Bursa Efek Indonesia (BEI) Tahun 2009-2013)

ABSTRAK Opini audit going concern yang diterima oleh sebuah perusahaan menunjukkan adanya kondisi dan peristiwa yang menimbulkan keraguan auditor akan kelangsungan hidup perusahaan. Opini audit going concern dapat digunakan sebagai peringatan awal bagi para pengguna laporan keuangan guna menghindari kesalahan dalam pembuatan keputusan. Beberapa penelitian mengenai faktorfaktor yang mempengaruhi terhadap opini audit going concern telah dilakukan. Namun, hasil penelitian tersebut masih menunjukkan ketidakkonsistenan. Penelitian ini bertujuan menguji kembali faktor-faktor yang berpengaruh terhadap opini audit going concern. Faktor-faktor yang diuji dalam penelitian ini lebih memfokuskan pada faktor debt default dan financial distress. Penelitian ini bertujuan untuk mengetahui besarnya pengaruh debt default dan financial distress terhadap opini audit going concern. Penelitian ini menggunakan perusahaan manufaktur yang terdaftar di Bursa Efek Indonesia periode 2009-2013 sebagai sampel penelitian. Berdasarkan hasil purposive sampling diperoleh 13 perusahaan manufaktur yang memenuhi kriteria sampel. Pengujian hipotesis dalam penelitian ini dilakukan dengan menggunakan analisis regresi logistik. Hasil pengujian hipotesis secara parsial menunjukan bahwa debt default berpengaruh signifikan terhadap opini audit going concern. Sedangkan financial distress tidak berpengaruh signifikan terhadap opini audit going concern, namun dengan arah koefisien yang negatif artinya semakin kecil nilai Zscorenya maka semakin besar terhadap penerimaan opini audit going concern. Berdasarkan hasil pengujian hipotesis secara simultan menunjukan bahwa debt default dan financial distress secara bersama-sama berpengaruh signifikan terhadap opini audit going concern.

The Media Work of Syrian Diaspora Activists : Brokering Between the Protest and Mainstream Media

The role of Syrian diaspora activists has been identified as key to both supporting and shaping the world’s image of the Syrian uprising. This article examines the multifaceted media work of Syrian diaspora activists, conceptualized as “cultural brokerage” in a global and national setting. Based on personal interviews with activists in exile in five countries, this study identifies and analyzes three main aspects of brokerage: (a) linking the voices of protesters inside the country to the outside world, (b) managing messages to bridge the gap between social media and mainstream media, and (c) collaborating with professional journalists and translating messages to fit the contexts and understandings of foreign publics.Peer reviewe

Calcium Ions Effect on Planaria Feeding Behavior

Calcium is important for the contraction of muscles, neurotransmission, and signaling in animals. Like other active movers, invertebrate planarian flatworms have musculature for motility. Therefore, it can be inferred that without the proper concentration of calcium ions in the water they can’t undulate or extend the pharynx, a muscular feeding structure. Planaria are generally cultured at a 0.5 g/L concentration of instant ocean sea salt (IOS), which contains calcium ion of 0.126 mM. However, there is uncertainty in the concentrations of important ions, such as calcium, which are optimal for the maintenance and homeostasis of the planaria. Previous research on water quality and planarian behavior has focused on species Schmidtea mediterranea, Dugesia japonica, and Girardia guanjuatiensis, but not Girardia dorotocephala (G. dorotocephala), the species currently cultured at Lynn University. Because other than being just readily available these species of worms haven’t undergone research in the frame of calcium ions. G. dorotocephala may require different concentrations of calcium ions than those of other relative species, an analysis of their requirements is warranted. For this experiment, we plan to specify which concentration of calcium is required for G. dorotocephala cultures. We hypothesize that G. dorotocephala requires micronutrient concentrations differing from standard IOS water, as has been observed for other species of planaria. We base this hypothesis on our observations of their feeding behavior following starvation. To conduct this experiment, we plan to assay food localization behavior under different concentrations of calcium
