Generalized Video Deblurring for Dynamic Scenes

Several state-of-the-art video deblurring methods are based on a strong assumption that the captured scenes are static. These methods fail to deblur blurry videos in dynamic scenes. We propose a video deblurring method to deal with general blurs inherent in dynamic scenes, contrary to other methods. To handle locally varying and general blurs caused by various sources, such as camera shake, moving objects, and depth variation in a scene, we approximate pixel-wise kernel with bidirectional optical flows. Therefore, we propose a single energy model that simultaneously estimates optical flows and latent frames to solve our deblurring problem. We also provide a framework and efficient solvers to optimize the energy model. By minimizing the proposed energy function, we achieve significant improvements in removing blurs and estimating accurate optical flows in blurry frames. Extensive experimental results demonstrate the superiority of the proposed method in real and challenging videos that state-of-the-art methods fail in either deblurring or optical flow estimation.Comment: CVPR 2015 ora

Motivos trabajo inicial y la desmotivación en la enseñanza del inglés como lengua ex-­ tranjera: Los casos de los profesores coreanos

In order to broaden understanding of English as a foreign language (EFL) tea-­ cher motivation, this study examines Korean EFL teachers’ initial job motives and demotiva-­ ting factors. Four psychological constructs emerged regarding initial career motives: Global Orientation, Job Security, Altruism, and Ought-­to Self. Among the constructs, global orien-­ tation proved to be the most popular reason for choosing an EFL teaching career. This study also showed three constructs for detrimental factors on EFL teacher motivation: Obstacles to Communicative Language Teaching, Inadequate Administrative Support, and Lack of Social Recognition. It was shown that obstacles to communicative language teaching contributed to the greatest demotivation.Para la comprensión de inglés como lengua extranjera (EFL) motivación del profesorado, este estudio examina motivos de trabajo inicial y factores desmotivadores de los profesores coreanos. Cuatro constructos psicológicos surgieron con respecto a los moti-­ vos de trabajo inicial: orientación global, seguridad en el empleo, altruismo, y Ought-­to Self. Entre las constructos, orientación global resultó para ser la razón más popular para elegir una carrera de enseñanza de inglés como lengua extranjera. Este estudio también mostró tres constructos de factores perjudiciales en EFL motivación del profesorado: Los obstáculos de enseñanza de ingles como lengua extranjera. Este estudio también mostro tres constructores de factores perjudiciales en EFL motivación del profesorado: Los obstáculos de enseñanza comunicativa, la insuficiencia de apoyo administrativo, y la falta de reconocimiento social. Se ha demostrado que los obstáculos en enseñanza comunicativa ha contribuido a la mayor desmotivación

Online Video Deblurring via Dynamic Temporal Blending Network

State-of-the-art video deblurring methods are capable of removing non-uniform blur caused by unwanted camera shake and/or object motion in dynamic scenes. However, most existing methods are based on batch processing and thus need access to all recorded frames, rendering them computationally demanding and time consuming and thus limiting their practical use. In contrast, we propose an online (sequential) video deblurring method based on a spatio-temporal recurrent network that allows for real-time performance. In particular, we introduce a novel architecture which extends the receptive field while keeping the overall size of the network small to enable fast execution. In doing so, our network is able to remove even large blur caused by strong camera shake and/or fast moving objects. Furthermore, we propose a novel network layer that enforces temporal consistency between consecutive frames by dynamic temporal blending which compares and adaptively (at test time) shares features obtained at different time steps. We show the superiority of the proposed method in an extensive experimental evaluation.Comment: 10 page

Measuring Willingness to Accept for GM Food by Characteristics

Korean consumers' willingness to accept (WTA) for GM food are studied in this paper. This study compares hypothetical and nonhypothetical responses to choice experiment questions. We test for hypothetical bias in a choice experiment involving GM rice with differing characteristic attributes and multinomial logit model is applied to predict the estimated results. In general, hypothetical responses predicted higher probabilities of purchasing GM rice than nonhypothetical responses. Thus, hypothetical choices overestimate willingness to accept for GM rice. The results of this paper could contributes to government's GM food policies and subsequent studies, also improving economic welfare of farmers and consumers.GM Food, Willingness to Accept, Choice experiment, Hypothetical bias, Food Consumption/Nutrition/Food Safety,

Racial/ethnic differences in consumer financial capability: The role of financial education

This study examined the racial/ethnic differences in financial capability controlling for various factors focusing on the role of financial education. Furthermore, we investigated the contributing factors to clarify where such gap stems. Regression results using data from the 2018 U.S. National Financial Capability Study indicated that Whites had a higher level of financial capability across all indicators than other racial/ethnic minority groups. Respondents who participated in the financial education had a higher level of financial capability than those without financial education. Multiple sources, hours and quality of financial education were positively associated with the level of financial capability. Decomposition analyses showed that age, income, negative income shock and banking status contributed to explain the gaps of financial capability between Black and White respondents as well as between Hispanic and White respondents. Financial education was a contributing factor only to explain the Black–White difference and it may narrow the gap. However, we found substantial unexplained gaps between Black and Hispanic respondents attributed by unobservable characteristics. Results of this study provide important insights into the racial/ethnic disparities in financial capability that have implications for consumer policymakers, educators and researchers

Financial inclusion, financial capability, and financial fragility during the COVID-19 pandemic

Purpose: Financial inclusion can be proxied by banking status. The purpose of this study is to investigate the potential effects of financial capability on the financial fragility of U.S. adults with various banking statuses during the COVID-19 pandemic. Design/methodology/approach: This study utilized the 2021 National Financial Capability Study (NFCS) dataset to investigate the relationship between financial capability and financial fragility among consumers with different banking statuses. The analysis controlled for employment shocks, health shocks, and other consumer characteristics. Banking statuses included fully banked, under-banked (utilizing both banking and alternative financial services), and unbanked individuals. Logistic regression analyses were conducted on both the entire sample and subsamples based on banking statuses. Findings: The results showed that financial capability was negatively associated with financial fragility. The magnitude of the potential negative effect of financial capability was the greatest among the fully banked group, followed by the underbanked and unbanked groups. Respondents who were underbanked or unbanked were more likely to experience financial fragility than those who were fully banked. Additionally, respondents who were laid off or furloughed during the pandemic were more likely to experience financial fragility than those without employment shocks. The effect size of financial capability factors was greater than that of COVID-19 shock factors. These results suggest that higher levels of both financial capability and financial inclusion may be effective in reducing the risk of financial fragility. Originality: This study represents one of the first attempts to examine the potential effects of financial capability on financial fragility among consumers with various banking statuses during the COVID-19 pandemic. Furthermore, this study offers new evidence to determine whether COVID-19 shocks, as measured by health and employment status, are associated with financial fragility. Additionally, the effect size of financial capability factors is greater than that of COVID-19 shock factors. The results from the 2021 NFCS dataset provide valuable insights for banking professionals and public policymakers on how to enhance consumer financial wellbeing

Exploring the Demand for Retirement Planning Advice: The Role of Financial Literacy

This research extends previous literature on the relationship between financial literacy and financial advice seeking in three ways: (1) we examine financial planner use specifically within the context of retirement planning, (2) we incorporate Huston’s (2010) framework of financial literacy, and (3) we use longitudinal data to investigate the initiation, maintenance, and termination of financial planner use. Results from the 2010 and 2012 National Longitudinal Survey of Youth 1979 (NLSY79) show a positive association between the components of financial literacy and financial planner use for retirement planning
