In-Game Social Interactions to Facilitate ESL Students\u27 Morphological Awareness, Language and Literacy Skills

Video games that require players to utilize a target or second language to complete tasks have emerged as alternative pedagogical tools for Second Language Acquisition (SLA). With the exception of vocabulary acquisition, much of the prior research in game-based SLA fails to gauge students\u27 literacy skills, specifically their morphological awareness or understanding of the smallest meaningful linguistic units (e.g., prefixes, suffixes, and roots). Given this shortcoming, we utilize a two-player online game to facilitate social interactions between Native English Speakers (NES) and English as a Second Language (ESL) students as a mechanism to generate ESL students\u27 written output in the targeted language and draw attention to their morphological awareness. Analysis of chat logs demonstrates the game\u27s potential to enhance ESL students\u27 morphological awareness and other important L2 literacy skills such as word reading accuracy. Both NES and ESL students\u27 reflections of their gameplay experiences suggest game design modifications that promote ESL students\u27 willingness to communicate with NES while developing their morphological awareness and practicing their L2 communication and literacy skills

Depth of the 660-km discontinuity near the Mariana slab from an array of ocean bottom seismographs,

[1] High frequency records of deep Mariana earthquakes from a dense array of ocean bottom seismographs deployed in the Mariana arc and back-arc regions are stacked and searched for the phases P660p and S660p to constrain the depth of the 660-km discontinuity near the Mariana slab. Results of the high-resolution study suggest that around 18°N the 660-km discontinuity lies at about 710-730 km (±14 km) depth within or in the vicinity of the slab core. In the region seismicity ceases at $620 km depth. This implies that, although tomographic images show the Mariana slab penetrating into the lower mantle, deep seismicity in the region terminates$100 km above the base of the transition zone. These findings and similar observations in Tonga argue that factors other than the phase transition at the base of the upper mantle may control the maximum down-dip extent of the deep seismogenic region in the slab

Adaptation of the Basic Empathy Scale among a Portuguese sample of incarcerated juvenile offenders

The main aim of the present study was to examine the psychometric properties of the Basic Empathy Scale (BES) and of its adapted short version among a forensic sample of incarcerated male juvenile offenders (N = 221). The Portuguese validations of the BES and its adapted short version demonstrated good psychometric properties, namely in terms of the two-factor structure, internal consistency, convergent validity, discriminant validity, and concurrent validity that generally justifies its use among this population. Statistically significant associations were found with callous– unemotional traits and social anxiety. Findings are discussed in terms of the use of the BES and its adapted short version with juvenile offenders.This research was supported by the Portuguese Foundation for Science and Technology (FCT) with co-financing of the European Social Fund – POPH/FSE [grant number SFRH/BPD/86666/2012]

Direct determination of trace elements in powdered samples by in-cell isotope dilution femtosecond laser ablation ICPMS

A method has been developed for the direct and simultaneous multielement determination of Cu, Zn, Sn, and Pb in soil and sediment samples using femtosecond laser ablation inductively coupled plasma mass spectrometry (fs-LA-ICPMS) in combination with isotope dilution mass spectrometry (IDMS). The in-cell isotope dilution fs-LA-ICPMS method proposed in this work was based on the quasi-simultaneous ablation of the natural abundance sample and the isotopically enriched solid spike, which was performed using a high repetition rate laser and a fast scanning beam device in a combined manner. Both the sample preparation procedure and the total analysis time have been drastically reduced, in comparison with previous approaches, since a unique multielement isotopically enriched solid spike was employed to analyze different powdered samples. Numerous experimental parameters were carefully selected (e.g., carrier gas flow rate, inlet diameter of the ablation cell, sample translation speed, scanner speed, etc.) in order to ensure the complete mixing between the sample and the solid spike aerosols. The proposed in-cell fs-LA-ICP-IDMS method was tested for the analysis of two soil (CRM 142R, GBW-07405) and two sediment (PACS-2, IAEA-405) reference materials, and the analysis of Cu, Zn, Sn, and Pb yielded good agreement of usually not more than 10% deviation from the certified values and precisions of less than 15% relative standard deviation. Furthermore, the concentrations were in agreement not only with the certified values but also with those obtained by ICP-IDMS after the microwave-assisted digestion of the solid samples, demonstrating therefore that in-cell fs-LA-ICP-IDMS opens the possibility for accurate and precise determinations of trace elements in powdered samples reducing the total sample preparation time to less than 5 min. Additionally, scanning electron microscope measurements showed that the aerosol generated by in-cell fs-LA-ICP-IDMS predominantly consisted of linear agglomerates of small particles (in the order of few tens of nanometers) and a few large spherical particles with diameters below 225 nm

The relation between depressive and obsessive-compulsive symptoms in obsessive-compulsive disorder: Results from a large, naturalistic follow-up study

Objective Despite the frequent occurrence of depressive symptoms in obsessive-compulsive disorder (OCD), little is known about the reciprocal influence between depressive and obsessive-compulsive symptoms during the course of the disease. The aim of the present study is to investigate the longitudinal relationship between obsessive-compulsive and depressive symptoms in OCD patients. Method We used the baseline and 1-year follow-up data of the Netherlands Obsessive Compulsive Disorder Association (NOCDA) study. In 276 patients with a lifetime diagnosis of obsessive-compulsive disorder, depressive and obsessive-compulsive symptoms were assessed at baseline and at one-year follow-up with the Beck Depression Inventory (BDI) and the Yale-Brown Obsessive Compulsive Symptom (Y-BOCS) scale. Relations were investigated using a cross-lagged panel design. Results The association between the severity of depressive symptoms at baseline and obsessive-compulsive symptoms at follow-up was significant (β=0.244, p<0.001), while the association between the severity of obsessive-compulsive symptoms at baseline and depressive symptoms at follow-up was not (β=0.097, p=0.060). Replication of the analyses in subgroups with and without current comorbid major depressive disorder (MDD) and subgroups with different sequence of onset (primary versus secondary MDD) revealed the same results. Limitations There may be other factors, which affect both depressive and obsessive-compulsive symptoms that were not assessed in the present study. Conclusion The present study demonstrates a relation between depressive symptoms and the course of obsessive-compulsive symptoms in OCD patients, irrespective of a current diagnosis of MDD and the sequence of onset of OCD and MDD

Limitations of rupture forecasting exposed by instantaneously triggered earthquake doublet

Earthquake hazard assessments and rupture forecasts are based on the potential length of seismic rupture and whether or not slip is arrested at fault segment boundaries. Such forecasts do not generally consider that one earthquake can trigger a second large event, near-instantaneously, at distances greater than a few kilometers. Here we present a geodetic and seismological analysis of a magnitude 7.1 intra-continental earthquake that occurred in Pakistan in 1997. We find that the earthquake, rather than a single event as hitherto assumed, was in fact an earthquake doublet: initial rupture on a shallow, blind 2 reverse fault was followed just 19 seconds later by a second rupture on a separate reverse fault 50 km away. Slip on the second fault increased the total seismic moment by half, and doubled both the combined event duration and the area of maximum ground shaking. We infer that static Coulomb stresses at the initiation location of the second earthquake were probably reduced as a result of the first. Instead, we suggest that a dynamic triggering mechanism is likely, although the responsible seismic wave phase is unclear. Our results expose a flaw in earthquake rupture forecasts that disregard cascading, multiple-fault ruptures of this type

‘NOT A RELIGIOUS STATE’ A study of three Indonesian religious leaders on the relation of state and religion

This article explores the concept of a ‘secular state’ offered by three Indonesian religious leaders: a Catholic priest, Nicolaus Driyarkara (1913–1967), and two Muslim intellectuals who were also state officials, Mukti Ali (1923–2004) and Munawir Sjadzali (1925–2004). All three, who represented the immediate generation after the revolution for Indonesian independence from the Dutch (1945), defended the legitimacy of a secular state for Indonesia based on the state ideology Pancasila (Five Principles of Indonesia). In doing so, they argued that a religious state, for example an Islamic state, is incompatible with a plural nation that has diverse cultures, faiths, and ethnicities. The three also argued that the state should remain neutral about its citizens’ faith and should not be dominated by a single religion, i.e. Islam. Instead, the state is obliged to protect all religions embraced by Indonesians. This argument becomes a vital foundation in the establishment of Indonesia’s trajectory of unique ‘secularisation’. Whilst these three intellectuals opposed the idea of establishing a religious or Islamic state in Indonesia, it was not because they envisioned the decline of the role of religion in politics and the public domain but rather that they regarded religiosity in Indonesia as vital in nation building within a multi-religious society. In particular, the two Muslim leaders used religious legitimacy to sustain the New Order’s political stability, and harnessed state authority to modernise the Indonesian Islamic community
