Augmented Reality: An Overview and Five Directions for AR in Education

Augmented Reality (AR) is an emerging form of experience in which the Real World (RW) is enhanced by computer-generated content tied to specific locations and/or activities. Over the last several years, AR applications have become portable and widely available on mobile de- vices. AR is becoming visible in our audio-visual media (e.g., news, entertainment, sports) and is beginning to enter other aspects of our lives (e.g., e-commerce, travel, marketing) in tangible and exciting ways. Facilitating ubiquitous learning, AR will give learners instant access to location- specific information compiled and provided by numerous sources (2009). Both the 2010 and 2011 Horizon Reports predict that AR will soon see widespread use on US college campuses. In prepa- ration, this paper offers an overview of AR, examines recent AR developments, explores the impact of AR on society, and evaluates the implications of AR for learning and education.
Dominicanas Redefining HIV in San Pedro de Macorís

This study explored the social support among women impacted by human immunodeficiency virus (HIV) living in the Province of San Pedro de Macoris, Republica Dominicana. Social support is one way that social networks can influence health status. Social networks impact health behaviors and overall health outcomes which include infectious diseases, morbidity rates, and mortality rates. Social networks can promote health and minimize risky behavior: “cohesive, supportive networks may themselves blunt stressful experiences and enable people to resist risky behavior and maintain healthier choices” (Berkman, Kawachi, & Krishna, 2014, p. 248). Qualitative methods were used to explore how social support systems impacted the personal experience of women living with HIV. Each Dominican woman described her own moral trajectory ranging from non-acceptance of HIV as an incurable disease to acceptance of living with HIV as a health condition in everyday life. The thematic analysis indicates that social support was instrumental for each woman throughout her journey and process of coming to terms with her HIV diagnosis and taking control of her life. Family, God, the Clinica Esperanza y Caridad (Clinic) and the support group were forms of social support frequently expressed in their narratives and represented their social networks.
On the Role of Experiencer in the Interaction of Aspect and Unaccusativity in Russian

In this paper I identify the factors that can skew the result of two standard unaccusativity diagnostics in Russian (distributive po-phrase and verb prefixation): (i) animacy of the subject (ii) verbal aspect. I introduce a new class of data, which reveals a contrast that is characteristic of all unaccusative predicates: Experiencer/ Theme interaction. Unlike the well-known agentivity effects (Permutter and Postal (1984), Hoekstra and Mulder (1990), Zaenen (1993)), Experiencer/Theme interaction is linked to animacy, but not to volitionality. The connection between animacy and an Experiencer is formalized as an Experiencer condition: the Experiencer role must be assigned if the sole argument is animate. I propose a novel view of argument distribution whereby animate arguments can be base generated VP-externally. Variable applicability of unaccusative tests to telic/atelic verb forms results from the interaction between the Experiencer condition, the structural view of telicity (Folli and Harley (2005), Ramchand (2008)) and world knowledge.

La formación y el desarrollo profesional del profesorado en España y Latinoamérica

Much has been said about the professional development of teachers, but has rarely been compared what happens between different Spanish-speaking coun tries as in the case of Spain and Latin-American countries. Therefore, the purpose of this article is to describe and analyze teacher training and professional deve lopment in Spain and Latin America in general. This paper presents clearly con cepts as training and professional development, including an analysis of the role of the teacher and what unites and separates Spain and Latin American countries in terms of teachers’ professional development and presents some differences identified in the context between Latin-American countries and Spain.
[Validity and reliability of the Turkish version of the Wender Utah Rating Scale for attention-deficit/hyperactivity disorder in adults].

OBJECTIVE To determine reliability and validity of Turkish form of the 25 item Wender Utah Rating Scale (WURS), which is designed as an aid for diagnosis of Attention-Deficit/Hyperactivity Disorder (ADHD) in adults. METHOD The scale was administered to 59 patients who were diagnosed as having ADHD according to DSM-IV criteria after comprehensive psychiatric and neuropsychological assessments in outpatient clinics of University of Ankara Medical School, Department of Psychiatry. Control groups consisted of 59 patients with depression, 44 patients with bipolar affective disorder in remission, and 145 healthy controls. Subjects who were illiterate and younger than 18 years of age were excluded from the study. WURS was readministered to 63 of the healthy controls after 4 weeks. RESULTS Principal components analysis revealed 5 factors explaining 61.3% of the variance. The factors were labeled as Irritability, Depression, School Problems, Behavioral Problems/Impulsivity and Attentional Deficits. Mean factor scores of ADHD group was higher than all groups except Depression factor. Turkish form of WURS demonstrated excellent internal consistency (Cronbach's alpha= 0.93), and the test-retest coefficient for the WURS (total score) was 0.81. Item-total score correlations varied between 0.31-0.75. A cut off score of 36 or higher identified 82.5% of the adults with ADHD (sensitivity), 90.8% of the healthy controls (specificity), 66% of patients with depression, and 64.3% of patients with bipolar affective disorder correctly. CONCLUSION Turkish form of the WURS is a reliable and valid scale in assessing childhood symptoms in adults for ADHD. However overlapping mood disorder items lowers specificity of the scale.
Effect of Fe-enrichment on seismic properties of perovskite and post-perovskite in the deep lower mantle

Recent experimental measurements of the equation of state of perovskites and post-perovskites in the (Mg,Fe)SiO3 and (Mg,Fe,Al)(Fe,Al,Si)O-3 systems over a wide range of iron contents are used to constrain the effects of Fe and Al on density and bulk modulus of these phases at deep mantle pressures. The density of Fe-bearing perovskite follows a linear relationship with Fe-content at a representative mid-mantle depth of 1850 km (80 GPa): (80) (g cm(- 3)) = 5.054(1) + 1.270(3)X-Fe. The bulk modulus of silicate perovskite is not sensitive to Fe-content and follows the relationship, K-80 (GPa) = 546(2) + 12(25)X-Fe. The velocity heterogeneity parameter, partial derivative ln V-B/partial derivative X-Fe, determined by experimental values for the bulk sound speed is 0.10(1), in agreement with theory and the behaviour of other Fe-bearing silicates. Near the core-mantle boundary, Fe-rich post-perovskite is observed to be more compressible than the Mg-end-member, in contrast to theoretical predictions. From experimental data, the densities of perovskite and post-perovskite at 125 GPa (2700 km depth) are (125,Pv) (g cm(-3)) = 5.426(11) + 1.38(4)X-Fe and (125,pPv) (g cm(-3)) = 5.548(1) + 1.41(3)X-Fe. The density contrast across the post-perovskite transition is similar to 2 per cent, irrespective of Fe-content, but the contrast in bulk sound speed increases with Fe-content. Al-rich silicates exhibit no significant differences in density or compressibility relative to Al-free silicates, but may be responsible for seismic heterogeneities due to differences in the depth and width of the post-perovskite transition. Observations of increased densities in large low shear velocity provinces and ultra-low-velocity zones may be consistent with local iron enrichment from Mg#90 to Mg# 78-88 and Mg# < 50, respectively.
The role of environmental boundaries in the ontogeny of the hippocampal neural code for space

The hippocampal formation (HF) contains neurons whose firing represents a code for the position and orientation of an animal in space, across the vertebrate group. We studied the ontogeny of such spatially-tuned firing in the rat HF, investigating how and when sensory inputs are combined in order to construct a neural code for space during development. During the first 2-4 weeks of post-natal life, rats progressively begin to walk, explore their environment, and display learning in tests of spatial memory. Concurrently, spatially-tuned cell types emerge in the HF; first Head Direction cells at postnatal day 14 (P14), then Place cells, which gradually mature between P14 and P45, and finally Grid cells, which emerge from P20 onwards. In this study, we investigated the developmental time-course of another class of spatially-tuned cell, Boundary Vector Cells (BVCs), and what functional role they might play in development. BVCs are found in the subiculum of the HF, and encode proximity to the boundaries of an animal’s environment. We found subiculum neurons which fired selectively in response to the walls of the recording arena from P17 onwards. We tested whether the firing of such cells generalises to all boundaries to movement by; 1) introducing a barrier into the centre of the recording arena, 2) placing the animal in a completely novel recording arena and 3) removing the walls of the familiar recording arena, leaving the rat on an open platform. From P17 onwards, we found subiculum neurons which continued to respond to boundaries to movement in all three of these conditions. Finally, we asked what functional role BVCs could serve, particularly in relation to developing Place cells. We found that there was a striking correlation between the distance of a Place cell’s field from the closest wall, and the within- and across-trial spatial stability of its place field, in the youngest rat pups (P14 – P21). However, this correlation was absent in both adults and post-weanling rats (P22-P30). Boundaries to movement may therefore exert a significant influence on the developing hippocampus, acting to stabilise Place cell firing at the earliest stages of development.
Developments In Business Simulation & Experiential Learning , Volume 24 , 1997 PLOTTING BRAND TRAJECTORIES WITH THE COMPETE PPM PACKAGE : A MARKET SEGMENTATION ANALYSIS AND POSITIONING TOOL

The COMPETE PPM Package (Version LO) is used by competing participant teams in the marketing simulation COMPETE (Faria, Nulsen, and Roussos 1994) to generate a product positioning map (Kotler 1994) and to plot their own and competing brand trajectories. This product-positioning map enables a competing firm to identify which brands are in the premium, highvalue, penetration or rip-off strategy quadrants and to formulate a coherent marketing strategy. The product-positioning map is used together with VALS psychographic profiles and psycho-geodemo-graphic segmentation data concerning the target market to position their brands appropriately.
Application of Clustering Techniques Using Prioritized Variables in Regional Flood Frequency Analysis—Case Study of Mahanadi Basin

The selection of suitable site characteristics and the number of clusters play an important role for finding homogeneous regions in regional flood frequency analysis. The present study investigates the partition of the Mahanadi basin into homogeneous regions by applying different clustering techniques by using fewer but influential variables. As such, the entire basin is not hydrometeorologically homogeneous. Principal component analysis has been initiated in finding appropriate site characteristics (variables) as per priority. Out of seven variables, four variables are selected on priority. Possible numbers of cluster are found by applying the Kohonen self-organization map and Andrews plot. Other clustering techniques, such as hierarchical clustering fuzzy C-mean (FCM) and K -mean, are applied on prioritized variables to verify the result of clustering. The intercomparison of clustering techniques gives the optimum number of sites to be placed in a particular cluster. The sites clustered as per FCM give .
Federal Reserve Bank of New York Staff Reports Monetary Policy Implementation Frameworks : A Comparative Analysis

We compare two stylized frameworks for the implementation of monetary policy. The first framework relies only on standing facilities, and the second one relies only on open market operations. We show that the Friedman rule cannot be implemented in the first framework, but can be implemented using the second framework. However, for a given rate of inflation, we show that the first framework unambiguously achieves higher welfare than the second one. We conclude that an optimal system of monetary policy implementation should contain elements of both frameworks. Our results also suggest that any such system should pay interest on both required and excess reserves.
Efisiensi Penggunaan Jumlah Bibit Terhadap Pertumbuhan dan Produksi Padi Sawah Efficiency of Used The Number of Seedling on Growth an Production of Lowland Rice

The number of seedlings per hill of rice plants affects the level of productivity , the use of seeds per hill with the right amount of rice production. This research aims to determine the effect of the number of seeds/clump on the growth and production of rice. Research using randomized block design (RBD) consists of five treatments with four replications. The treatments tested were: A (1 seedling/hill), B (3 seedling/hill), C (5 seedling/hill), D (7 seedling/hill), and E (9 seedling/hill). The seeds used are Batang Piaman variety, 25x25 cm spacing. The experiment sites in lowland farmers Lubuk Minturun Sungai Lareh village, Koto Tangah district, Padang city, West Sumatra province on wed season 2009/2010. Fertilizer is given as 150 kg Urea, 100 kg SP36 and 75 kg KCl per hectare. Urea and KCl are given three times, with brocasting system at 7, 28, and 45 Days After Planting (DAP), while the SP36 is given at 7 DAP combined with Urea and KCl. The results showed the treatment number of seedlings provide significant effect (P<0.05) on the number of grains per panicle and grain yield. However, no significantly effect (P<0.05) on plant height, maximum number of tillers, number of productive tillers, panicle length, percentage of empty grains, and weight of 1000 grains. The use number of seedlings less than five seedling per hill produces the high number of seeds per panicle and grain yield per hectare. Based on these results it can be concluded that the number of seed on the rice crops are not more than five seedling per hill.
A new velocity field for Greece: Implications for the kinematics and dynamics of the Aegean

[1] A new set of geodetic velocities for Greece and the Aegean, derived from 254 survey-mode and continuous GPS sites, is used to test kinematic and dynamic models for this area of rapid continental deformation. Modeling the kinematics of the Aegean by the rotation of a small number (3–6) of blocks produces RMS misfits of ∼5 mm yr−1 in the southern Aegean and western Peloponnese, indicating significant internal strain within these postulated blocks. It is possible to fit the observed velocities to within 2–3 mm yr−1 (RMS) by models that contain 10 or more blocks, but many such models can be found, with widely varying arrangements of blocks, that fit the data equally well provided that the horizontal dimension of those blocks is not larger than 100–200 km. A continuous field of velocity calculated from the GPS velocities by assuming that strain rates are homogeneous on the scale of ∼120 km fits the observed velocities to better than 2–3 mm yr−1 (RMS), with systematic misfits, representing more localized strain, confined to a region approximately 100 × 100 km in size around the western Gulf of Corinth. This velocity field accounts for the major active tectonic features of Greece and the Aegean, including the widespread north-south extensional deformation and the distributed strike-slip deformation in the NE Aegean and western Greece. The T axes of earthquakes are aligned with the principal axes of elongation in the geodetic field, major active normal fault systems are perpendicular to those axes, and ∼90% of the large earthquakes in this region during the past 120 years took place within the areas in which the geodetic strain rate exceeds 30 nanostrain yr−1. These observations suggest that the faulting within the upper crust of the Aegean region is driven by forces that are coherent over a scale that is significantly greater than 100 km. It is likely that those forces arise primarily from differences in gravitational potential energy within the lithosphere of the region.

Consumers solve an optimal stopping problem in deciding if they want a new automobile and when in the model year to purchase it. This dynamic approach allows for determining how the mix of consumers evolves over the model year and for measuring consumers' substitution patterns across products and time. I find that temporal substitution is significant, driving consumers' entry into and exit from the market. Through counterfactuals, I show that because consumers will temporarily substitute to a large degree, failure to account for automakers' dynamic pricing strategies results in an inaccurate picture of the return to using pricing incentives. A further finding is that the large price discounts typically offered at the end of the model year result in price discrimination by inducing price-sensitive consumers to delay purchasing new vehicles until the later months of the model year. and Ahmed Khwaja, as well as seminar participants at Johns Hopkins University and the Federal Reserve Banks of Cleveland and New York, for comments and suggestions.

Abstract Countries' concerns about the value of their currency have been studied and documented extensively in the literature. Capital controls can be—and often are—used as a tool to manage exchange rate fl uctuations. This paper investigates whether countries can benefi t from using such a tool. We develop a welfare-based analysis of whether (or, in fact, how) countries should tax international borrowing. Our results suggest that restricting international capital fl ows through the use of these taxes can be benefi cial for individual countries, although it would limit cross-border pooling of risk. The reason is because, while consumption risk-pooling is important, individual countries also care about domestic output fl uctuations. Moreover, the results show that countries decide to restrict the international fl ow of capital exactly when this fl ow is crucial to ensure cross-border risk sharing. Our fi ndings point to the possibility of costly " capital control wars " and thus to signifi cant gains from international policy coordination.
Paradigm Shift: The New Promise of Information Technology

According to the authors, these changes have combined to create an entirely new paradigm for competitive information processing - now and for the future. This book zeros in on changes such as the shift from proprietary to open systems, from host-based to network-based systems, and stand-alone to integrated software applications.
Quantum Computing : A New Frontier in Distributed Systems or Science Fiction ?

Quantum computing and distributed systems may enter a mutually beneficial partnership in the future. On the one hand, it is much easier to build a number of small quantum computers rather than a single large one. On the other hand, the best results concerning some of the fundamental problems in distributed computing can potentially be dramatically improved upon by taking advantage of the superior resources and processing power that quantum mechanics offers. This survey has the purpose to highlight both of these benefits. We first review the current results regarding the implementation of arbitrary quantum algorithms on distributed hardware. We then discuss existing proposals for quantum solutions of leader election — a fundamental problem from distributed computing. Quantum mechanics allows leader election to be solved with no communication, provided that certain pre-shared entanglement is already in place. Further, an impossibility result from classical distributed computing is circumvented by the quantum solution of anonymous leader election — a unique leader is elected in finite time with certainty. Finally, we discuss the viability of these proposals from a practical perspective. Although, theoretically, distributed quantum computing looks promising, it is still unclear how to build quantum hardware and how to create and maintain robust large-scale entangled states. Moreover, it is not clear whether the costs of creating entangled states and working with them are smaller than the costs of existing classical solutions.
