The VLA/ALMA Nascent Disk and Multiplicity (VANDAM) Survey of Orion Protostars. II. A Statistical Characterization of Class 0 and Class I Protostellar Disks
We have conducted a survey of 328 protostars in the Orion molecular clouds with the Atacama Large Millimeter/submillimeter Array at 0.87 mm at a resolution of ~0.”1 (40 au), including observations with the Very Large Array at 9 mm toward 148 protostars at a resolution of ~0 08 (32 au). This is the largest multiwavelength survey of protostars at this resolution by an order of magnitude. We use the dust continuum emission at 0.87 and 9 mm to measure the dust disk radii and masses toward the Class 0, Class I, and flat-spectrum protostars, characterizing the evolution of these disk properties in the protostellar phase. The mean dust disk radii for the Class 0, Class I, and flat-spectrum protostars are 44.9^(+5.8)_(−3.4), 37.0^(+4.9)_(−3.0), and 28.5^(+3.7)_(−2.3) au, respectively, and the mean protostellar dust disk masses are 25.9^(+7.7)_(−4.0), 14.9^(+3.8)_(−2.2), 1.6^(+3.5)_(−1.9) M⊕, respectively. The decrease in dust disk masses is expected from disk evolution and accretion, but the decrease in disk radii may point to the initial conditions of star formation not leading to the systematic growth of disk radii or that radial drift is keeping the dust disk sizes small. At least 146 protostellar disks (35% of 379 detected 0.87 mm continuum sources plus 42 nondetections) have disk radii greater than 50 au in our sample. These properties are not found to vary significantly between different regions within Orion. The protostellar dust disk mass distributions are systematically larger than those of Class II disks by a factor of >4, providing evidence that the cores of giant planets may need to at least begin their formation during the protostellar phase

Trade Adjustment Assistance (TAA) and Its Role in U.S. Trade Policy
[Excerpt] When Congress passed the Reciprocal Trade Agreements Act (RTAA) of 1934, it reflected an important transition in “national trade policy” away from “protectionism” toward greater “trade liberalization.” This shift continues to be the dominant, but hardly uncontested, trade policy of the United States. The substantial national gains from trade have long been recognized, yet trade liberalizing legislation often faces strong political opposition because related costs, although much smaller, affect a vocal and concentrated constituency. Congress first addressed this inherent tension with legislation that allowed for the reimposition of tariffs and other trade barriers when domestic industries were threatened or hurt by imports. In 1962, however, Congress adopted an additional approach by providing trade adjustment assistance (TAA) directly to trade-affected firms and workers. It remains a controversial pillar of U.S. trade policy today.
This report discusses the role of TAA in U.S. trade policy, from its inception as a legislative option in the early 1950s, to its core role as an alternative to import relief that many argue has served to promote the long-term U.S. trade liberalization agenda. It will also consider the extent to which TAA has been linked to both renewal of trade agreements authority, and passage of trade agreement implementing legislation. TAA has become an integral part of an increasingly complex U.S. trade policy. Understanding the origins of TAA, the historical congressional debate, and legislative options considered by Congress over the past 50 years may help inform the current discussion of TAA reauthorization
German Idealism Meets Indian Vedanta and Kasmiri Saivism
Regarding each philosophy as a variation of that of Spinoza, this article compares the German Idealism of Schelling and Hegel with the Indian Vedanta of Sa?kara and Ramanuja, as well as Abhinavagupta\u27s Kasmiri Saivism. It argues that only Hegel\u27s philosophy does not fail. For Śaṅkara, Ramanuja, Abhinavagupta, and Schelling, the experience of ultimate reality—Brahman for Śaṅkara and Ramanuja, Siva for Abhinavagupta, the Absolute for Schelling—is self-authenticating and so excludes the possibility of error. However, there is also no possibility of truth as no criterion distinguishes truth from error when individuals make contradictory claims. By contrast, Hegel\u27s Geist is an extended mind that potentially encompasses the human community. Geist develops historically. Experience is conceptual and concepts must be socially recognized to be legitimate. Experience is fallible, for Hegel, and better accounts are obtained through mutual criticism. Although disagreement represents an impassible impasse for Sa?kara, Ramanuja, Abhinavagupta, and Schelling, it is the road forward for Hegel
Rural Students\u27 College Choice and the Impact of Dual Enrollment Programs and College Cost
This article explores the college-choice processes of two college students who graduated high school from rural areas in New York State. Hossler and Gallagher’s (1987) three-stage model of the college-choice process was used as the theoretical framework for this study. To gain in-depth knowledge about students’ predisposition, search, and choice stages, narrative inquiry was employed. This article specifically highlights how dual enrollment courses played key roles within the college-choice processes of these students. These findings suggest that there is a need for additional education about college costs and dual enrollment programs for rural students and their families
The Effect of Space and Furnishings on Academic Readiness Scores of West Virginia Preschoolers
The effect of space and furnishings, as measured by the Early Childhood Environment Rating Scale – Revised (ECERS-R), on the School Readiness Composite (SRC) of the Bracken Basic Concept Scale –Revised (BBCS-R) was investigated. The data analyzed was collected as part of the West Virginia Educare Initiative and included the SRC from 65 preschool students, ranging in age from 2 years, 6 months to 5 years, 0 months. The first subtest score on the ECERS-R, space and furnishings, was also calculated for each child’s classroom. The Spearman rank correlation coefficient between the SRC on the BBCS-R and the space and furnishings score on the ECERS-R was .26 at the .05 level of significance. Due to the low level of the correlation coefficient and lack of research in this area, duplicate studies are needed
Implicit measures of actual versus ideal body image : relations with self-reported body dissatisfaction and dieting behaviors
Body dissatisfaction refers to a negative appreciation of one’s own body stemming from a discrepancy between how one perceives his/her body (actual body image) and how he/she wants it to be (ideal body image). To circumvent the limitations of self-report measures of body image, measures were developed that allow for a distinction between actual and ideal body image at the implicit level. The first goal of the present study was to investigate whether self-reported body dissatisfaction is related to implicit measures of actual and ideal body image as captured by the Relational Responding Task (RRT). Secondly, we examined whether these RRT measures were related to several indices of dieting behavior. Women high in body dissatisfaction (n = 30) were characterized by relatively strong implicit I-am-fat beliefs, whereas their implicit I-want-to-be-thinner beliefs were similar to individuals low in body dissatisfaction (n = 37). Implicit body image beliefs showed no added value over explicit body image beliefs in predicting body dissatisfaction and dieting behavior. These findings support the idea that the interplay between ideal and actual body image drives (self-reported) body dissatisfaction. However, strong support for the view that it would be critical to differentiate between explicit and implicit body image beliefs is missing
