The Impact

Both the campaign and subsequent election of Donald Trump have brought about marked changes in the overall tone of American political discourse. It is thought that these changes have been particularly disruptive to the public’s view of Hispanic immigration. To evaluate the current state of Hispanic political opinion regarding immigration, this study draws upon data from a survey conducted in January 2018 of 1,080 people of Hispanic descent currently living in the United States or Puerto Rico. Researchers looked at the impact of age, gender, language preference, time lived in the United States, and knowing an undocumented immigrant on participants’ views of immigration. Taking the survey in Spanish and knowing an undocumented immigrant were found to be the most influential factors in determining a favorable view of undocumented immigrants as well as a perceived increase in discrimination toward Hispanics since Trump’s election.

Disadvantaged Communities

As the Internet penetration in the United States increases, many digital divide researchers have delved into the parent–child dynamics regarding family digital access and use. However, little attention has been paid to digital parenting in terms of monitoring, guiding, and regulating children’s digital lives, especially in the context of disadvantaged communities. As an initial step to fill the critical gaps in related literature, this study casts light on factors that affect the self-efficacy of digital parenting in disadvantaged urban communities. Using a census survey of public housing households in one of the largest public housing authorities in the United States, we found that single motherhood and home Internet access significantly accounted for low–socioeconomic status parents’ digital parenting self-efficacy. We also found that parental engagement in children’s school activities strongly affected their digital parenting self-efficacy. By contrast, we found that other sociodemographic and socioeconomic factors (i.e., gender, education, race/ethnicity), mobile Internet access, parents’ homework help, and educational expectation fail to be contributing factors.

This study analyzes construction productivity based on the construction duration per floor and per gross area over 20 years (1996–2015) and compares the results among the United States, United Kingdom, South Korea, and Japan, which have similar sizes of total construction investment and market risk. Although construction labor productivity is widely used to analyze and compare construction productivity among countries, it does not consider the changed construction duration caused by levels of investment and technology. Therefore, construction duration per floor and gross area was selected analyze and compare construction productivity in this paper. Regular and non-modular buildings with a total of five or more floors and a basement are collected during the analysis period (1996–2015). The total number of collected buildings is 800 and it includes buildings in the United States (194), the United Kingdom (186), South Korea (322) and Japan (98). Construction duration, increase rate and standard deviation are then compared between each country. Finally, factors that influence construction duration are derived and additionally considered to explain and adjust the trends and changes of construction productivity related to construction duration in the four countries. The productivity of the United States is the highest, but the difference between it and other countries decreases steadily because the increase rate of the construction duration in the United stated is larger than those of other countries. Then, the factors influencing the construction duration are derived as a learning effect by the number of ground floors and gross area, as well as the rate of constructed buildings with a first basement floor for efficient productivity management. The rate of the first basement floor influences both the construction duration per floor and per gross area. This study contributes to the field by explaining the productivity change based on the construction duration and proposing the key management point of the productivity by deriving the influence factors

Lygodium Japonicum

Lygodium japonicum (Thunb.) Swartz (Family, Schizaeaceae) is naturally distributed from Asia to Australia and has naturalized in the United States from Texas to the Carolinas and Florida (4). Recently, it has been declared a Category I weed (the most invasive group) by the Florida Exotic Pest Plant Council. A foliar rust fungus was observed on a population of L. japonicum growing under the canopy of a pine/hardwood forest in Gainesville, FL. The lower surfaces of almost all the pinnules (foliage) were covered with cinnamon-brown eruptive pustules. Necrotic areas developed around mature, erupted, and coalesced pustules. Severely infected foliage were wilted and dried. Microscopic observations of the pustules and spore morphology revealed these eruptive structures to be uredinia. The dimensions (24.6 [+ 2.2] × 29.7 [+ 3.5] μm) and morphology (ellipsoid or obovoid, pale cinnamon-brown, and echinulate with indistinct pores) of urediniospore were similar to those reported for Puccinia lygodii (Har.) Arth. (Uredinales) (1). Therefore, the rust was identified as P. lygodii and confirmed by J. Hennen. P. lygodii is native to South America, where it has been recorded from L. volubile and L. venustum (2). This rust was previously identified as Milesia and Uredinopsis spp. on L. japonicum from Louisiana and Florida, respectively (3). Herein, we report the performance of Koch's postulates for P. lygodii on L. japonicum. Excised foliage bearing uredinia from plants collected near Gainesville were placed in a flask, flooded with deionized distilled water, shaken vigorously for a few minutes, and the suspension strained through four layers of cheesecloth. Urediniospores suspended in the filtrate were concentrated to 1.0 × 106 spores/ml, using sedimentation technique, and then misted onto 3-week-old foliage of fully expanded fronds of four juvenile L. japonicum plants grown in pots, until the foliage were completely wet. The plants were then covered with a plastic bag and placed in dappled shade. After 3 days, the bags were removed and the water-filled containers were placed around L. japonicum plants to maintain high ambient humidity. During the remaining 4-week experimental period, the temperature and relative humidity under the shaded areas ranged from 23 to 38°C and 38 to 93%, respectively. The plants were monitored daily for development of symptoms characteristics of P. lygodii. Minute cinnamon-brown flecks appeared on the foliage 20 days after inoculation. Within 3 to 5 days, these flecked areas expanded, erupted, and formed uredinia on the lower surface of the symptomatic foliage. The morphology and size range of the uredinia and urediniospores were the same as those of the P. lygodii applied in this test. This is the first report confirming pathogenicity of P. lygodii on L. japonicum. P. lygodii may be a potential biological control agent of L. japonicum in the Southeast United States.

Prostate adenocarcinoma is the most common malignant tumor of men in the United States and is the third leading cause of death in men. Despite attempts at early detection, there will be 244,000 new cases and 44,000 deaths from the disease in the United States in 1995. Therapeutic progress against this disease is hindered by an incomplete understanding of prostate epithelial cell biology, the availability of human tissues for in vitro experimentation, slow dissemination of information between prostate cancer research teams and the increasing pressure to “ stretch” research dollars at the same time staff reductions are occurring.To meet these challenges, we have used the correlative microscopy (CM) and client/server (C/S) computing to increase productivity while decreasing costs. Critical elements of our program are as follows:1) Establishing the Western Pennsylvania Genitourinary (GU) Tissue Bank which includes >100 prostates from patients with prostate adenocarcinoma as well as >20 normal prostates from transplant organ donors.

In recent years it became apparent that we needed to improve productivity and efficiency in the Microscopy Laboratories in GE Plastics. It was realized that digital image acquisition, archiving, processing, analysis, and transmission over a network would be the best way to achieve this goal. Also, the capabilities of quantitative image analysis, image transmission etc. available with this approach would help us to increase our efficiency. Although the advantages of digital image acquisition, processing, archiving, etc. have been described and are being practiced in many SEM, laboratories, they have not been generally applied in microscopy laboratories (TEM, Optical, SEM and others) and impact on increased productivity has not been yet exploited as well.In order to attain our objective we have acquired a SEMICAPS imaging workstation for each of the GE Plastic sites in the United States. We have integrated the workstation with the microscopes and their peripherals as shown in Figure 1.

Communities Of Interest

Every ten years, the United States “constructs” itself politically. On a decennial basis, U.S. Congressional districts are quite literally drawn, physically constructing political representation in the House of Representatives on the basis of where one lives. Why does the United States do it this way? What justifies domicile as the sole criteria of constituency construction? These are the questions raised in this article. Contrary to many contemporary understandings of representation at the founding, I argue that there were no principled reasons for using domicile as the method of organizing for political representation. Even in 1787, the Congressional district was expected to be far too large to map onto existing communities of interest. Instead, territory should be understood as forming a habit of mind for the founders, even while it was necessary to achieve other democratic aims of representative government.
