3D face tracking and multi-scale, spatio-temporal analysis of linguistically significant facial expressions and head positions in ASL

Essential grammatical information is conveyed in signed languages by clusters of events involving facial expressions and movements of the head and upper body. This poses a significant challenge for computer-based sign language recognition. Here, we present new methods for the recognition of nonmanual grammatical markers in American Sign Language (ASL) based on: (1) new 3D tracking methods for the estimation of 3D head pose and facial expressions to determine the relevant low-level features; (2) methods for higher-level analysis of component events (raised/lowered eyebrows, periodic head nods and head shakes) used in grammatical markings—with differentiation of temporal phases (onset, core, offset, where appropriate), analysis of their characteristic properties, and extraction of corresponding features; (3) a 2-level learning framework to combine lowand high-level features of differing spatio-temporal scales. This new approach achieves significantly better tracking and recognition results than our previous methods

Effects of Teaching Resourcefulness and Acceptance on Affect, Behavior, and Cognition of Chronically Ill Elders

This clinical trial examined changes in affect, behavior, and cognition in 176 chronically ill elders who were randomly assigned to Resourcefulness Training (RT), Acceptance Training (AT), or Diversional Activities (DA). The RT group improved on affect (t(1,42) = 4.91; p \u3c .001) and cognition (t(1,42) = 2.03; p\u3c .05) and these effects lasted 12 weeks. The AT group improved on affect (t(1,36) = 3.08; p \u3c .01), but this improvement did not persist. The RT and AT groups both showed positive behavior changes after six weeks. There were no changes in the DA group. The findings suggest that teaching elders resourcefulness and acceptance of chronic conditions may promote healthy functioning and improve their quality of life

Guangzhou Buyers Preference for Premium Hawaiian Grown Product Gift Baskets

Guangzhou buyers' preference for premium Hawaiian grown product gift baskets with conjoint analysis was examined. Relative importance of three gift basket attributes: container type, products origin, and price were examined. Expenditure equivalent index to evaluate how much more each of the gift basket attributes is worth to the buyer was estimated. Main conclusions are: products have to be 'made in Hawaii' to receive the premium price; business buyers are generally less willing to pay a high price; and individual buyers are more willing to pay the higher priced Koa gift basket.Chinese survey data, conjoint analysis, buyer preference, Hawaii gift baskets, Demand and Price Analysis,

Community environment, cognitive impairment and dementia in later life: results from the Cognitive Function and Ageing Study

Background: Few studies have investigated the impact of the community environment, as distinct from area deprivation, on cognition in later life. This study explores cross-sectional associations between cognitive impairment and dementia and environmental features at the community level in older people. Method: The postcodes of the 2424 participants in the year-10 interview of the Cognitive Function and Ageing Study in England were mapped into small area level geographical units (Lower-layer Super Output Areas) and linked to environmental data in government statistics. Multilevel logistic regression was conducted to investigate associations between cognitive impairment (defined as MMSE3 in GMS-AGECAT) and community level measurements including area deprivation, natural environment, land use mix and crime. Sensitivity analyses tested the impact of people moving residence within the last two years. Results: Higher levels of area deprivation and crime were not significantly associated with cognitive impairment and dementia after accounting for individual level factors. Living in areas with high land use mix was significantly associated with a nearly 60% reduced odds of dementia (OR: 0.4; 95% CI: 0.2, 0.8) after adjusting for individual level factors and area deprivation, but there was no linear trend for cognitive impairment. Increased odds of dementia (OR: 2.2, 95% CI: 1.2, 4.2) and cognitive impairment (OR: 1.4, 95% CI: 1.0, 2.0) were found in the highest quartile of natural environment availability. Findings were robust to exclusion of the recently relocated. Conclusion: Features of land use have complex associations with cognitive impairment and dementia. Further investigations should focus on environmental influences on cognition to inform health and social policies

The IS Core - VI: Further Along the Road to the IT Artifact

In one of the recent additions to the IS identity and diversity discussion, Alter questions the definition and relevance of IT artifact as defined by Benbasat and Zmud. In terms of definition, we believe that there is no substantial difference between Alter\u27s work system construct and IT artifact. However, when it comes to enhancing the relevance of and guiding the diversity in IT research, Alter\u27s boundary based approach may be less powerful than a core, IT-artifact based approach. Alter\u27s focus on systems, nonetheless, has it merits and therefore we suggest a possible convergence of Alter and Benbasat and Zmud\u27s constructs

Do Reconciliations Of Segment Earnings Affect Stock Prices?

While SFAS No. 131 is intended to increase the transparency of financial reporting using a “management approach,” it may reduce shareholders’ ability to interpret segment disclosures relative to the ‘industry approach’ employed under SFAS No.14. This study investigates whether segment reconciliation differences affect stock prices and whether abnormal returns can be earned using information about two components of earnings: aggregated segment earnings and segment earnings reconciliations. We compute reconciliations as the difference between firm-level consolidated earnings and aggregated segment-level earnings. Firms that report negative SERs have greater sales and profitability, greater return on equity, as well as more operating cash flows and firm growth. This suggests that firms that report aggregated segment earnings greater than firm-level consolidated earnings may be better off financially. Our findings show that mispricing does occur when firms report positive SERs by the market, underestimating the segment earnings reconciliation component of earnings persistence. Investors can also earn positive abnormal returns when investors take a long (short) position with the portfolio with the highest (lowest) absolute SERs. On the contrary, we find investors earn negative abnormal returns when firms report negative SERs. Collectively, this study provides evidence that mispricing occurs and that investors over/underestimate the importance and/or persistence of segment earnings reconciliations

Nanoscale field effect transistor for biomolecular signal amplification

We report amplification of biomolecular recognition signal in lithographically defined silicon nanochannel devices. The devices are configured as field effect transistors (FET) in the reversed source-drain bias region. The measurement of the differential conductance of the nanowire channels in the FET allows sensitive detection of changes in the surface potential due to biomolecular binding. Narrower silicon channels demonstrate higher sensitivity to binding due to increased surface-to-volume ratio. The operation of the device in the negative source-drain region demonstrates signal amplification. The equivalence between protein binding and change in the surface potential is described

Effect of acupressure on postpartum low back pain, salivary cortisol, physical limitations, and depression: a randomized controlled pilot study

Objective: To investigate the effect of acupressure on postpartum low back pain (LBP), salivary cortisol, physical limitations, and postpartum depression. Methods: Participants were 70 postpartum women who were randomly assigned to either an intervention (n = 35) or a control (n = 35) group. The intervention group received 10 acupressure sessions (1 session per day, 5 d per week). The control group received 10 sham acupressure sessions. Outcomes were assessed using a visual analogue scale (LBP intensity), salivary cortisol values (LBP biomarker), and Chinese versions of the Roland-Morris Disability Questionnaire (daily activity limitations), Oswestry Disability Index (physical activity limitations), and the Edinburgh Postnatal Depression Scale (postpartum depression). Results: Participants in the intervention group had significantly lower levels of LBP intensity, daily activity limitations, physical activity limitations, and postpartum depression than those in the control group. There was no significant between-group difference in salivary cortisol. Conclusion: Acupressure may reduce postpartum LBP intensity and limitations in daily and physical activity, and alleviate postpartum depressive symptoms. Acupressure should be offered in postpartum care settings as an alternative treatment for postpartum women with LBP

Decision Making, IT Governance, and Information Systems Security

The complex issue of IS security involves organizational factors. Decision making, an important area of organizations, however, has only been studied to a limited extent in relation to IS security. In this paper we explore the relationship between organizational distribution of decision rights and IS security. We review the security literature and identify three aspects of an organization as what we term the pillars bolstering the success of IS security – people, processes/structures, and technology. We top our IS Security Architecture with the integrative truss of IS security strategy. Employing Weill and Ross’ (2004) IT governance archetypes, we link this IS Security Architecture to IT governance, and propose that IT governance patterns can enhance security when the governance archetype in place matches the decision profile required by a security practice

Field Effect Transistor Nanosensor for Breast Cancer Diagnostics

Silicon nanochannel field effect transistor (FET) biosensors are one of the most promising technologies in the development of highly sensitive and label-free analyte detection for cancer diagnostics. With their exceptional electrical properties and small dimensions, silicon nanochannels are ideally suited for extraordinarily high sensitivity. In fact, the high surface-to-volume ratios of these systems make single molecule detection possible. Further, FET biosensors offer the benefits of high speed, low cost, and high yield manufacturing, without sacrificing the sensitivity typical for traditional optical methods in diagnostics. Top down manufacturing methods leverage advantages in Complementary Metal Oxide Semiconductor (CMOS) technologies, making richly multiplexed sensor arrays a reality. Here, we discuss the fabrication and use of silicon nanochannel FET devices as biosensors for breast cancer diagnosis and monitoring
