A study of color image quality with respect to screen angle arrangement in multicolor halftone printing

The advantage of using a single screen-angle (Dot-on-Dot) reproduction for multicolor halftone printing is a sharper reproduction with the decrease, of. a rosette pattern in all image areas. The purpose of this study was to quantify the differences of color image quality between conventional reproduction using four screen-angles and a single screen-angle printing technique. In addition, the influence of screen frequency to the final color image quality in the Dot-on-Dot printing was also investigated. The results of this study confirmed that there is a linearity of image quality for all color halftone printing regardless of the arrangement of the screen angle. Test results also indicated that Dot-on-Dot was preferable to the conventional four screenangle technique at the low screen frequency. Under different reproduction circumstances, input image quality and reproduction screen frequency have different weight toward determining the quality of the final reproduction

Exothermic isospin-violating dark matter after SuperCDMS and CDEX

We show that exothermic isospin-violating dark matter (IVDM) can make the results of the latest CDMS-Si experiment consistent with recent null experiments, such as XENON10, XENON100, LUX, CDEX, and SuperCDMS, whereas for the CoGeNT experiment, a strong tension still persists. For CDMS-Si, separate exothermic dark matter or isospin-violating dark matter cannot fully ameliorate the tensions among these experiments; the tension disappears only if exothermic scattering is combined with an isospin-violating effect of f_n/f_p=-0.7. For such exothermic IVDM to exist, at least a new vector gauge boson (dark photon or dark Z') that connects SM quarks to Majorana-type DM particles is required.Comment: 12 pages, 6 figure

Income-based inequality in post-disaster migration is lower in high resilience areas : evidence from US internal migration

Residential relocation following environmental disasters is an increasingly necessary climate change adaptation measure. However, relocation is among the costliest individual-level adaptation measures, meaning that it may be cost prohibitive for disadvantaged groups. As climate change continues to worsen, it is important to better understand how existing socioeconomic inequalities affect climate migration and how they may be offset. In this study we use network regression models to look at how internal migration patterns in the United States vary by disaster-related property damage, household income, and local-level disaster resilience. Our results show that post-disaster migration patterns vary considerably by the income level of sending and receiving counties, which suggests that income-based inequality impacts both individuals' access to relocation and the ability of disaster-afflicted areas to rebuild. We further find evidence that income-based inequality in post-disaster outmigration is attenuated in areas with higher disaster resilience, not due to increased relocation out of poorer areas but instead because there is decreased relocation from richer ones. This finding suggests that, as climate adaptation measures, relocation and resilience-building are substitutes, with the implication that resilience incentivizes in situ adaptation, which can be a long term drain on individual wellbeing and climate adaptation resources.Peer reviewe

AN EMPIRICAL STUDY ON THE PHYSICIANS’ BEHAVIORAL INTENTION WITH ELECTRONIC MEDICAL RECORD SYSTEMS IN TAIWAN

Currently in healthcare organizations paper-based patient record management faces many challenges. Most countries are promoting the full implementation of electronic medical records in every hospital. Medical environments change frequently and dramatically, which makes full acceptance of electronic medical records (EMR) by physicians an important issue. This empirical study combines the theory on reasoned action (TRA) and information technology acceptance model (TAM) resulted in a modified TAM to find what critical factors influence the acceptance behavior of EMR by physicians. To test these hypotheses, this study administered a cross-sectional mailed questionnaire survey during the period of three months in 2012. The survey was deployed to1000 physicians randomly from the estimated total 2000 physicians of 50 regional acute hospitals (more than 300 beds) in Taiwan currently. From these, 252effective responses were received, resulting in a net response rate of 25%. These research findings indicate that four variables significantly positively impact the intention to adopt EMR. Among these, attitude has the most significant positive impact on adoption intentions. Moreover, it shows that the professional autonomy might play an important role to moderate the attitude with significant statistics. These results maintain enough explanatory power (R2 =78.4%) to help explain the attitudes and intentions of physicians in adopting electronic medical record information systems. Our analysis revealed the importance of the perception usefulness which moderated by professional autonomy and pragmatism by physicians for their adoption electronic medical record systems in clinical practice

Intercounty Commuter Public Transit Services and Opportunities in the Central Bluegrass

This report reviews the current state of available public transportation services in central Kentucky, with a focus on the Lexington-Fayette County commutershed. Within the region, this report identifies the major public transportation providers, describes the transit services available through them, and examines the potential opportunities of intercounty commuter public transportation services. Using intercounty commuting data obtained from the 2006-2008 Census Transportation Planning Products (CTPP), this report estimates the potential need and opportunity for additional transit services. Lastly, this report argues for the viability of vanpools as an efficient and cost-effective strategy for addressing the shortage of intercounty commuter transit services

Health, environmental, and animal rights motives for vegetarian eating.

Health, the environment, and animal rights represent the three main reasons people cite for vegetarian diet in Western societies. However, it has not been shown that these motives can be distinguished empirically, and little is known about what kind of people are likely to be compelled by these different motives. This study had three goals. First, we aimed to use construct validation to test whether develop health, environmental, and animal rights motives for a vegetarian diet could be distinguished. Second, we evaluated whether these motivations were associated with different demographic, behavioral, and personality profiles in three diverse samples. Third, we examined whether peoples' motivations were related to responses to vegetarian advocacy materials. We created the Vegetarian Eating Motives Inventory, a 15-item measure whose structure was invariant across three samples (N = 1006, 1004, 5478) and two languages (English and Dutch). Using this measure, we found that health was the most common motive for non-vegetarians to consider vegetarian diets and it had the broadest array of correlates, which primarily involved communal and agentic values. Correlates of environmental and animal rights motives were limited, but these motives were strong and specific predictors of advocacy materials in a fourth sample (N = 739). These results provide researchers with a useful tool for identifying vegetarian motives among both vegetarian and non-vegetarian respondents, offer useful insights into the nomological net of vegetarian motivations, and provide advocates with guidance about how to best target campaigns promoting a vegetarian diet
