Computer Vision based Assistive Technology for Blind and Visually Impaired People
Venue: ICCCNT

The computer vision based assistive technology for the blind and visually impaired is a developing area. The assistive technology helps the visually impaired by providing them with a greater independence. By enabling them with their day to day activities like indoor and outdoor navigation, obstacle detection, locating the doors and lost objects, etc. Even though different assistive technologies are available for the blind, most of them have complex designs which are developed for a specific purpose and are expensive for the commercial production. Rather than depending on a traditional white cane, the blind and visually impaired people can make use of the cheaper assistive device proposed in this paper. The proposed system incorporates several assistance features in a device which will be an asset for them according to their needs.

Multi Dimensional SCMA Codebook Design Based on Constellation Rotation and Interleaving
Venue: 2016 IEEE 83rd Vehicular Technology Conference (VTC Spring)

Sparse code multiple access (SCMA) is a new non orthogonal multiple access scheme, which effectively exploits the shaping gain of multi dimensional codebook. In this paper, a multi dimensional SCMA (MD SCMA) codebook design based on constellation rotation and interleaving method is proposed for downlink SCMA systems. In particular, the first dimension of mother constellation is constructed by subset of lattice Z2. Then the other dimensions are obtained by rotating the first dimension. Further, the interleaving is used for even dimensions to improve the performance in fading channels. In this way, we can design different codebooks for the aim of spectral efficiency or power efficiency. And the simulation results show that the bit error rate (BER) performance of MD SCMA codebooks outperforms that of the existing SCMA codebooks and low density signature (LDS) in downlink Rayleigh fading channels.
IoT Privacy and Security Challenges for Smart Home Environments
Venue: Inf.

Often the Internet of Things (IoT) is considered as a single problem domain, with proposed solutions intended to be applied across a wide range of applications. However, the privacy and security needs of critical engineering infrastructure or sensitive commercial operations are very different to the needs of a domestic Smart Home environment. Additionally, the financial and human resources available to implement security and privacy vary greatly between application domains. In domestic environments, human issues may be as important as technical issues. After surveying existing solutions for enhancing IoT security, the paper identifies key future requirements for trusted Smart Home systems. A gateway architecture is selected as the most appropriate for resource constrained devices, and for high system availability. Two key technologies to assist system auto management are identified. Firstly, support for system auto configuration will enhance system security. Secondly, the automatic update of system software and firmware is needed to maintain ongoing secure system operation.
The Role of Peer Interaction and Second Language Learning for ESL Students in Academic Contexts: An Extended Literature Review

This literature review explores the relationship between language proficiency and ESL students' experiences in higher education contexts, with specific reference to the role of conversational peer interaction. The two major concerns that guide this review are (a) the academic challenges faced by students from an ESL background in relation to conversational interaction, and (b) the impact of conversational language proficiency on their overall academic experience. The studies reviewed in this project suggest that insufficient language proficiency results in several challenges for ESL students, most notably the inability to share their expertise and knowledge with their peers and participate successfully in classroom oral discussions. In addition, however, the literature suggests that language proficiency has a strong impact on the overall experiences of students and their abilities to navigate the social structures of the academic community and establish their own identity.
Colorism and educational outcomes of Asian Americans: evidence from the National Longitudinal Study of Adolescent Health

Using a nationally representative longitudinal data set, the current study examines the link between colorism and educational attainment of Asian American young adults. Three levels of educational attainment are used as outcomes: high school diploma, some college and a Bachelor's degree or higher. Independent variables include skin tone, ethnic origin, parental income and education, family structure, parental involvement, family social support and others. Given the fact that colorism affects genders disparately, the analyses are conducted separately for males and females. The findings suggest that, compared to their co ethnics with light brown skin tone, Asian American males and females with white skin are more likely to be college educated. Conversely, the odds of getting a Bachelor's degree or higher are significantly higher for Asian Americans with light skin tone than for their co ethnics with dark brown skin tone. All in all, the findings point to the pattern of the inverse relationship between educational attainment and the darkness of skin tone.
Educational outcomes of Asian and Hispanic Americans: The significance of skin color

Existing evidence suggests that skin tone is an important determinant of one's life chances. Although social science research has a strong tradition of elucidating the link between race and educational outcomes, the effect of skin color on educational attainment has not received adequate attention. The main objective of the present investigation was, using a national representative longitudinal data, to evaluate educational attainment of Asian American and Hispanic young adults in the United States as a function of skin tone and other co variates. Separate analyses were carried out for Mexican Americans, Puerto Ricans, other Hispanics, East Asian, Filipino American and other Asians. Additional analyses were conducted on a subsample of sibling pairs of Asian and Hispanic origin. Control variables included family socio economic background, parental involvement, family social support, average school SES and others. Although we observed a certain degree of cross ethnic heterogeneity, the results consistently point to a strong association between educational attainment and the lightness of skin tone. The findings also suggest that the aforementioned relationship is the strongest among U.S. young adults of Filipino and Puerto Rican descent.
A national benchmark investigation of return to work outcome rates between African American, Native American or Alaskan Native, Latino, Asian American or Pacific Islander, and Non Latino White veterans served by state vocational rehabilitation agencies: Application of bootstrap data expansion

Research examining the provision of effective state vocational rehabilitation agency (SVRA) sponsored services is pertinent to improving successful return to work outcomes among veterans of color (i.e. African Americans, Native Americans or Alaska Natives, Latinos, and Asian Americans or Pacific Islanders versus non Latino Whites) To date, however, scant attention has been paid to examining these target groups' outcome patterns.  This study employed a stratified bootstrap data expansion approach to assess the relationship between race/ethnicity, gender, level of educational attainment at closure and return to work among veterans with a signed individualized plan for employment (IPE)  National fiscal year (FY) 2013 Rehabilitation Services Administration (RSA) 911 case records (N= 11,603) were extracted and re sampled across multiple trials using bootstrap procedures to increase logistic regression model accuracy.  The findings indicated that African American and female veterans were statistically significantly less likely to return to work compared to non Latino White and female veterans, respectively. Return to work probabilities were 'poorest' for African American veterans followed by Native Americans or Alaska Natives, Asian Americans or Pacific Islanders, Latinos, and then non Latino Whites.

Melanoma Perception in People of Color: A Targeted Educational Intervention
Venue: American Journal of Clinical Dermatology

BackgroundAlthough melanoma is more common in non Hispanic Whites, ethnic minorities face a greater risk of melanoma related mortality, which may be partially attributed to presentation at atypical sites and a lack of awareness.ObjectiveOur objective was to assess the effectiveness of a melanoma educational intervention targeted towards people of color.DesignParticipants received one of two scripted melanoma educational interventions in the summer of 2015. They completed surveys before the intervention, immediately post intervention, and 2 months post intervention.SettingDermatology clinic at an academic hospital.ParticipantsA consecutive sample of 100 participants who self identified as African American, Asian, or Hispanic were recruited following their dermatology visit. In total, 70 participants completed the 2 month follow up questionnaire.InterventionThe comparison intervention group received an educational intervention using a conventional pamphlet on the 'ABCDEs' (Asymmetry, Borders, Color, Diameter, Evolution) of melanoma. The targeted intervention group received a modified pamphlet that included a skin of color section, the nomenclature "melanoma skin cancer" and an image of an individual performing a skin self examination with the help of a friend.Main Outcomes and MeasuresMelanoma knowledge, perceived risk for developing melanoma, and skin self examination practices were assessed through self reported questionnaires.ResultsAmong the 100 participants, 78% self identified as African American, 11% as Asian, and 11% as Hispanic. Both groups experienced a similar increase in melanoma knowledge that was retained at 2 months. Perceived personal risk for developing melanoma increased more in the targeted intervention group immediately post intervention (p 0.015) but this difference no longer existed between the groups at the 2 month follow up. The targeted intervention group also demonstrated a greater increase in skin self examinations (p 0.048) and knowledge of warning signs to look for when examining the skin (p 0.002) at the 2 month follow up.Conclusions and RelevanceThe educational intervention targeted towards people of color resulted in increased skin self examinations. Educational material that is relevant to ethnic minorities may better promote early detection and help to decrease the disparity in melanoma related morality rates.
A Virtual Reality Full Body Illusion Improves Body Image Disturbance in Anorexia Nervosa
Venue: PloS one

Patients with anorexia nervosa (AN) have a persistent distorted experience of the size of their body. Previously we found that the Rubber Hand Illusion improves hand size estimation in this group. Here we investigated whether a Full Body Illusion (FBI) affects body size estimation of body parts more emotionally salient than the hand. In the FBI, analogue to the RHI, participants experience ownership over an entire virtual body in VR after synchronous visuo tactile stimulation of the actual and virtual body.  We asked participants to estimate their body size (shoulders, abdomen, hips) before the FBI was induced, directly after induction and at ~2 hour 45 minutes follow up. The results showed that AN patients (N 30) decrease the overestimation of their shoulders, abdomen and hips directly after the FBI was induced. This effect was strongest for estimates of circumference, and also observed in the asynchronous control condition of the illusion. Moreover, at follow up, the improvements in body size estimation could still be observed in the AN group. Notably, the HC group (N 29) also showed changes in body size estimation after the FBI, but the effect showed a different pattern than that of the AN group.  The results lead us to conclude that the disturbed experience of body size in AN is flexible and can be changed, even for highly emotional body parts. As such this study offers novel starting points from which new interventions for body image disturbance in AN can be developed.
Arbuscular mycorrhiza improved phosphorus efficiency in paddy fields

Arbuscular mycorrhizal fungi (AMF) were supposed to improve phosphorus (P) efficiency in paddy fields. Our aim was to investigate the roles of AMF inoculation in increasing P acquisition efficiency (PAE) by cutting down P loss and in enhancing P use efficiency (PUE) via optimizing shoot P investment. A field experiment with two factors was carried out in northeast of China: six fertilizer levels were provided, inoculation with Glomus mosseae was either conducted or not at each fertilizer level. We investigated P loss during the rice growing season while P uptake and investment, biological and economic yields of rice were estimated at maturity. Then, we calculated recovery efficiency (RE) utilization efficiency (UE) and agronomic efficiency (AE) for PAE and physiological efficiency (PE) and agrophysiological efficiency (APE) for PUE. Both apparent and balanced values of these indicators were calculated. In addition, relationships of balanced PAE P loss and balanced PUE P investment were investigated for the two sets of plants. We found that AMF inoculation improved root colonization and the economic yield but decreased the biological yield and seasonal P loss. Inoculation led to more P allocated to panicles but less to stems and leaves, without affecting shoot P uptake. We also found that the apparent RE, UE and AE were smaller in inoculated treatments while greater apparent PE and balanced AE and APE was observed in inoculated treatments. Additionally, P loss of paddy fields decreased exponentially as balanced PAE increased and inoculation reduced P loss, without affecting balanced PAE. For the two sets of plants, balanced PE was negatively correlated with shoot P invested in panicles but positively with shoot P invested in stems. Furthermore, inoculation did not significantly altered the relationship between balanced PE and shoot P invested in panicles and stems. Conclusively, our study highlights the importance of AMF inoculation in improving P efficiency of rice production.
The Multisensory Nature of Verbal Discourse in Parent Toddler Interactions
Venue: Developmental neuropsychology

Toddlers learn object names in sensory rich contexts. Many argue that this multisensory experience facilitates learning. Here, we examine how toddlers' multisensory experience is linked to another aspect of their experience associated with better learning: the temporally extended nature of verbal discourse. We observed parent toddler dyads as they played with, and as parents talked about, a set of objects. Analyses revealed links between the multisensory and extended nature of speech, highlighting inter connections and redundancies in the environment. We discuss the implications of these results for our understanding of early discourse, multisensory communication, and how the learning environment shapes language development.
Adaptations of Prefrontal Brain Activity, Executive Functions, and Gait in Healthy Elderly Following Exergame and Balance Training: A Randomized Controlled Study
Venue: Front. Aging Neurosci.

During aging, the prefrontal cortex (PFC) undergoes age dependent neuronal changes influencing cognitive and motor functions. Motor learning interventions are hypothesized to ameliorate motor and cognitive deficits in older adults. Especially, video game based physical exercise might have the potential to train motor in combination with cognitive abilities in older adults. The aim of this study was to compare conventional balance training with video game based physical exercise, a so called exergame, on the relative power (RP) of electroencephalographic (EEG) frequencies over the PFC, executive function (EF) and gait performance. Twenty seven participants (mean age 79.2 7.3 years) were randomly assigned to one of two groups. All participants completed 24 trainings including three times a 30 min session/week. The EEG measurements showed that theta RP significantly decreased in favor of the exergame group [L(14) 6.23, p 0.007] Comparing pre vs. post test, EFs improved both within the exergame (working memory: z 2.28, p 0.021; divided attention auditory: z 2.51, p 0.009; divided attention visual: z 2.06, p 0.040; go/no go: z 2.55, p 0.008; set shifting: z 2.90, p 0.002) and within the balance group (set shifting: z 2.04, p 0.042) Moreover, spatio temporal gait parameters primarily improved within the exergame group under dual task conditions (speed normal walking: z 2.90, p 0.002; speed fast walking: z 2.97, p 0.001; cadence normal walking: z 2.97, p 0.001; stride length fast walking: z 2.69, p 0.005) and within the balance group under single task conditions (speed normal walking: z 2.54, p 0.009; speed fast walking: z 1.98, p 0.049; cadence normal walking: z 2.79, p 0.003) These results indicate that exergame training as well as balance training positively influence prefrontal cortex activity and/or function in varying proportion.
