Geometric morphology can be influenced by several biotic and abiotic factors, including predator–prey interactions and habitat structure. We measured the external morphology of Micropterus salmoides (largemouth bass, LMB) from two states in north-eastern United States, to assess the potential divergence of body shape. LMB varied in overall body shape (canonical variate analysis, P<0.001) between states, with Maine populations exhibiting shorter jaws (ANOVA, P<0.001) and thicker caudal peduncle depths (ANOVA, P<0.001) than the LMB in Pennsylvania. We propose that these observed differences in morphological traits suggest that jaw length may be influenced by prey availability and resource utilisation, whereas peduncle depth is better explained by surrounding habitat structure. These findings showed that body shape is variable and is influenced by a complex array of environmental factors, even over small latitudinal differences.

Gray leaf spot caused by Magnaporthe oryzae is a serious disease of perennial ryegrass (Lolium perenne) turf in golf course fairways in the United States and Japan. Genetic relationships among M. oryzae isolates from perennial ryegrass (prg) isolates within and between the two countries were examined using the repetitive DNA elements MGR586, Pot2, and MAGGY as DNA fingerprinting probes. In all, 82 isolates of M. oryzae, including 57 prg isolates from the United States collected from 1995 to 2001, 1 annual ryegrass (Lolium multiflorum) isolate from the United States collected in 1972, and 24 prg isolates from Japan collected from 1996 to 1999 were analyzed in this study. Hybridization with the MGR586 probe resulted in approximately 30 DNA fragments in 75 isolates (designated major MGR586 group) and less than 15 fragments in the remaining 7 isolates (designated minor MGR586 group). Both groups were represented among the 24 isolates from Japan. All isolates from the United States, with the exception of one isolate from Maryland, belonged to the major MGR586 group. Some isolates from Japan exhibited MGR586 fingerprints that were identical to several isolates collected in Pennsylvania. Similarly, fingerprinting analysis with the Pot2 probe also indicated the presence of two distinct groups: isolates in the major MGR586 group showed fingerprinting profiles comprising 20 to 25 bands, whereas the isolates in the minor MGR586 group had less than 10 fragments. When MAGGY was used as a probe, two distinct fingerprint types, one exhibiting more than 30 hybridizing bands (type I) and the other with only 2 to 4 bands (type II), were identified. Although isolates of both types were present in the major MGR586 group, only the type II isolates were identified in the minor MGR586 group. The parsimony tree obtained from combined MGR586 and Pot2 data showed that 71 of the 82 isolates belonged to a single lineage, 5 isolates formed four different lineages, and the remaining 6 (from Japan) formed a separate lineage. This study indicates that the predominant groups of M. oryzae associated with the recent outbreaks of gray leaf spot in Japan and the United States belong to the same genetic lineage.

Abstract Natural resources of North America ensured the existence of German immigrants in the late 17th century. In Pennsylvania and North Carolina, measures for forest protection and sustainable forestry were invoked at an early date. Efforts were based on inventory of the resources and controlled use. During the 18th and 19th centuries, German emigration was boosted by the scarcity of wood. Proto-industry in Germany strongly depended on wood and coal resources, causing negative effects in the forest and environment. Increasing population and developing industrialization devastated the forests. International scientific contact in forestry started during the American Revolutionary War. German influence on American forestry began in 1873, when the Austro-Hungarian government hosted an international exhibition in Vienna. German forest scientists and politicians focused on sustainable forestry and initiated a fundamental forest education system in the United States. An intensive German–American exchange on a professional basis took place until the beginning of World War II. The acquired historical knowledge on this subject demonstrates that German and North American environmental perception had interacted considerably.

Utah sweetvetch (Hedysarum boreale Nutt.) is a native American perennial nitrogen fixing legume used mainly in rangeland reclamation, soil rejuvenation, and erosion control. In June 2011, a field of Utah sweetvetch grown for seeds in central Oregon had approximately 15% of the plants exhibiting chlorosis, defoliation, stunting, wilting, and/or death. Dissection of the crown of symptomatic plants revealed discolored pinkish brown vascular tissue. Symptomatic tissues from six random plants were surface sterilized, placed on acidified potato dextrose agar (PDA) medium, and cultured for 7 days at room temperature, which allowed six fungal isolates (SS1 through SS6) to be collected. On PDA, all six isolates had rapid, creamy white colored growth. Based on observations of 1-week-old isolates, microconidia were oval to kidney shaped, single celled, 8 to 10 × 2.5 to 4 μm, and formed at the tips of long unbranched monophialides. Macroconidia were three to four septate, cylindrical to slightly curved, with characteristic foot shaped basal cell and blunt apical cell, 37 to 49 × 4.4 to 5.3 μm. Chlaymydospores observed were 8.5 to 11 × 7.6 to 9 μm. Based on fungal references (1,2,3), the isolates were identified as Fusarium solani (Mart.) Sacc. Identification of the isolates at the molecular level was determined by amplification of the internal transcribed spacer (ITS) region using PCR and amplicon sequencing. Botrytis cinerea and F. graminearum cultures were used as controls for the extraction, amplification, and sequencing steps. Genomic DNA was extracted from mycelia using protocols of the MOBIO Ultraclean Soil DNA Isolation Kit (MO-BIO Laboratories Inc, Carlsbad, CA, USA). PCR was performed using ITS1/ITS4 primers and resulted in 563- to 573-bp amplicons, which were sequenced. Analysis of the ITS sequences (GenBank Accession Nos. JX524018 to JX524023) for the six fungal isolates using BLASTn revealed a 99% sequence identity with F. solani strains (AB470903, AB513851, AJ608989, EF152426, EU029589, and HM214456). Pathogenicity was confirmed on Utah sweetvetch plants in the greenhouse. Seeds of Utah sweetvetch were first plated on acidified PDA for germination; healthy seedlings were then selected and transplanted into pots with sterilized soil after 2 weeks of growth. The plants were kept in a greenhouse at Central Oregon Agricultural Research Center, Madras, Oregon. Ten 40-day-old healthy vetch plants were inoculated by drenching with a mixed conidial suspension (107 conidia/ml) of the six F. solani isolates. Ten plants drenched with sterile distilled water were included as controls. Symptoms of chlorosis and stunting similar to those in the commercial field were observed within 30 days of inoculation on 8 of 10 inoculated plants, while control plants were symptomless. Fungal isolates identical to F. solani were reisolated from the symptomatic plants. To our knowledge, this is the first report of F. solani on Utah sweetvetch plants. References: (1) C. Booth.

Pachysandra terminalis Siebold & Zucc. (Japanese pachysandra, spurge) is widely used as a groundcover. In early 2012, Japanese pachysandra plants from Missouri, which originated in Pennsylvania, showed symptoms of light and dark green mosaic, leaf deformation, concentric ringspots, and stunting. Initial screening of symptomatic leaf tissue by transmission electron microscopy (TEM) using partially purified extracts confirmed the presence of spherical (~28 nm) and bacilliform (18-nm diameter, 35- to 58-nm length) virus particles. Immunosorbent electron microscopy (ISEM) using antisera to a clover isolate of Alfalfa mosaic virus (AMV) (PVAS 92) and to Cucumber mosaic virus (CMV) (ATCC PVAS-30) obtained from the American Type Culture Collection, Manassas, VA, confirmed the presence of AMV and CMV. No other type of virus-like particles were observed by TEM. After 6 months, nearly 20% of the 4,000 pachysandra cuttings exhibited the described symptoms. However, it is possible that more than 20% of the cuttings were infected with both viruses and not yet exhibiting symptoms. Reverse-transcription PCR (RT-PCR) was done using total RNA extracted with a Qiagen RNeasy kit and Ready-To-Go RT-PCR beads (GE Healthcare, UK Limited, UK). The primer pair CMV-1 (5′-GCCGTAAGCTGGATGGACCA) and CMV-2 (5′-TATGATAAGAAGCTTGTTTTCGCG) were used (3) to obtain a 502-bp amplicon from the coat protein (CP) region of CMV RNA 3. The product was ligated and cloned (pGEM-T Easy Vector System; Promega, USA). Three clones were sequenced (UMGC, USA), and the consensus sequence (Sequencher 5.1, Gene Codes Corp., USA) was deposited in GenBank (Accession No. JX227938). The sequence obtained had 100% identity with a homologous CP CMV sequence (AFQ94058) and 99% identity with several other homologous CP CMV sequences (CAX62443, CCK24369, and 15 others). It also contained an EcoRI site at nucleotides 332 to 337, characteristic of CMV Type II isolates (3). The primer pair AMV1F (5′-ATCCACCGATGCCAGCCTTA) and AMV1R (5′-TTCCGCCTCACTGCTGCTG) generated a 1,047-bp product from AMV RNA1 that was deposited in GenBank (JX227937). This product had 100% identity with a homologous AMV sequence (AFQ94057), and 99% identity with several other homologous AMV sequences (AGV15824, ADO85715, CBX36144). From the data presented here, it was concluded that the pachysandra had a mixed infection of AMV and a Type II isolate of CMV. Occurrence of AMV in pachysandra was first reported in New Jersey in 1982 (2) and reported for the first time in France and Germany in 2000 (1). The presence of CMV infection in pachysandra has not been reported in the present literature. Some of the symptoms associated with AMV infection in pachysandra in New Jersey (2) and Europe (1) were similar to the symptoms produced by pachysandra plants infected with both viruses (ring spots, mosaic, and line patterns). However, some symptoms were unique to the mixed infection in pachysandra by AMV and CMV (leaf deformation, stunting). A potential source of this co-infection could occur when plants are grown near alfalfa fields (AMV infection by aphids) and undergo vegetative propagation (CMV infection by contaminated tools). This is the first report of pachysandra co-infected by AMV and CMV in the United States. References: (1) L. Cardin and B. Moury. Plant Dis. 84:594, 2000. (2) D. E. Hershman and E. H. Varney.

Recent investigation of bacteria isolated from samples submitted to the Plant Disease Diagnostic Laboratory, Pennsylvania Department of Agriculture indicated that in 1995, Xanthomonas gardneri (ex Sutic 1957) (2) caused a leaf spot on tomato plants (Lycopersicon esculentum Mill.). In 1995, we examined 185 tomato and 36 pepper samples (13 field, 2 garden center, 38 greenhouse, 4 residence, 16 field-grown transplant, and 148 greenhouse-grown transplant samples). A processing company representative collected samples showing symptoms of bacterial spot of tomato on a hybrid, whole pack processing tomato, from a 16-ha field in Northumberland County, PA exhibiting almost 50% crop infection. Symptoms consisted of circular- to irregularly shaped, dark brown spots, <5 mm in diameter, and frequently with chlorotic haloes on leaves and stems. The center of a spot may be raised and scabby. Several spots on a single leaflet may coalesce and a portion or the entire leaflet may turn yellow or die. These symptoms were indistinguishable from those of bacterial spot caused by X. euvesicatoria, X. vesicatoria, and X. perforans. Bacterial streaming from lesions was evident under dark-field microscopy. Aerobic, gram-negative, yellow-pigmented, mucoid bacteria were isolated from the leaf spots and purified and stored in nutrient broth with 10% glycerol at –80°C. The 16S rRNA gene from a strain (PDA80951-95) typical of the cultures from these samples was sequenced (GenBank Accession No. GU573763). A BlastN search of GenBank revealed 100% nucleotide identity with the type strain of X. gardneri (XCGA2; No. AF123093). This strain also exhibited repetitive sequence-based (rep)-PCR profiles (4) identical to profiles of X. gardneri type strain XCGA2 DNA and produced a ~425-bp PCR product with BSX primers, a genetic marker indicative of X. gardneri (1). The strain was not amylolytic or pectolytic (2) and failed to utilize maltose, gentiobiose, and melezitose (3). For pathogenicity tests, inoculum was grown in nutrient broth with shaking for 24 h at 28°C. Inoculum was centrifuged, resuspended in sterile tap water, and adjusted to 2.5 × 108 CFU/ml. Lower leaf surfaces of tomato (cvs. Bonnie Best and Walter) and pepper (cvs. California Wonder and Early Niagara) plants were gently rubbed with sterile cheesecloth that was moistened with the inoculum. Strain PDA80951-95 caused leaf spots, with chlorotic haloes and occasional coalescence on both tomato and pepper, within 2 weeks at 15 s of mist per 20 min at 20 to 35°C in a secured greenhouse chamber. X. gardneri was only reisolated from symptomatic plants and its identity was confirmed by rep-PCR and absence of amylolytic and pectolytic activities. Negative controls consisting of X. campestris pv. campestris and sterile tap water did not show symptoms. A known type strain of X. gardneri was not included as a positive control for pathogenicity studies because this species is not known to occur in the United States (2). To our knowledge, this is the first report of bacterial spot on tomato plants caused by X. gardneri in Pennsylvania and the United States. Since the first occurrence in 1995, bacterial spot caused by X. gardneri reoccurred in Pennsylvania tomato fields in 2001 and consecutively from 2003 to 2009. Reference: (1) D. A. Cuppels et al.

Famous Chinese-American architect I.M. Pei was born in Guangdong, China in 1917.He traveled to the United States in 1935. Initially educated at the University of Pennsylvania, he continued his studies at the Massachusetts Institute of Technology (Bachelor of Architecture in 1940) and Harvard Graduate School of Design (Master of Architecture in 1946). I.M. Pei is widely praised for his bold design and clear geometric forms in his project. His career spanned 60 years and left many outstanding architectural works. I.M. Pei, revered as "the consummate master of modern architecture," his architectural philosophy was deeply influenced by modern art. During that era, New York City was known as the center of modern art. Among them, abstract expressionism, conceptualism and minimalism were on full display here. Many famous artists held grand exhibitions here and established their own studios. I.M. Pei spent most of his life in this place. When American modern art reached its peak in New York, many architects decided to use primitive forms to convey a concise and powerful artistic language, which also became their iconic design style. I.M. Pei's design philosophy is global. He emphasized: "In the architectural design process, there are three key aspects that require special attention: the first is the integration of the building with its environment; the second is how to handle space and form; and finally, from the user's point of view, to correctly solve functional problems. In this paper, the study analyzes the structural features of 12 architectural spaces of art museums designed by I.M. Pei in the context of the time line. It compares the similarities and differences in the spatial structure of the architecture of art museums built in the same time period as well as between different historical eras. The study focuses on analyzing the form and content of space and draws on the theoretical framework of contemporary architecture, namely the concepts of space within modernism. As a result of the analysis, two key characteristics of Pei's architecture are highlighted: sculptural and geometric.

Diabetic Retinopathy stands as a leading cause of irreversible blindness, necessitating frequent examinations, especially in the early stages where effective treatments are available. However, current examination rates vary widely, ranging from 25–60%. This study scrutinizes the Point-of-Care Diabetic Retinopathy Examination Program at the University of Pittsburgh/UPMC, delving into its composition, evolution, challenges, solutions, and improvement opportunities. Employing a narrative approach, insights are gathered from key stakeholders, including ophthalmologists and staff from primary care clinics. A quantitative analysis from 2008 to 2020 provides a comprehensive overview of program outcomes, covering 94 primary care offices with 51 retinal cameras. Program components feature automated non-mydriatic 45° retinal cameras, a dedicated coordinator, rigorous training, and standardized workflows. Over this period, the program conducted 21,960 exams in 16,458 unique individuals, revealing a diverse population with an average age of 58.5 and a balanced gender distribution. Average body mass index (33.96±8.02 kg/m2) and hemoglobin A1c (7.58%±1.88%) surpassed normal ranges, indicating prevalent risk factors for diabetes-related complications. Notably, 24.2% of patients underwent more than one exam, emphasizing program engagement. Findings indicated that 86.3% of exams were gradable, with 59.0% within normal limits, 12.1% showing some evidence of diabetic retinopathy, and 6.4% exhibiting vision-threatening diabetic retinopathy. Follow-up appointments with ophthalmologists were recommended in 31.5% of exams due to indeterminate results, positive diabetic retinopathy (≥moderate or macular exudate), or other findings like age-related macular degeneration or suspected glaucoma. The program demonstrated high reproducibility across diverse healthcare settings, featuring a sustainable model with minimal camera downtime, standardized workflows, and financial support from grants, health systems, and clinical revenues. Despite COVID-19 pandemic challenges, this research emphasizes the program’s reproducibility, user-friendly evolution, and promising outcomes. Beyond technical contributions, it highlights human factors influencing program success. Future research could explore adherence to follow-up ophthalmological recommendations and its associated factors.

The Plant Disease Diagnostic Laboratory of the Pennsylvania Department of Agriculture received diseased geranium (Pelargonium × hortorum) samples from several Pennsylvania (PA) greenhouses in 1999 and 2000 and from one Delaware (DE) greenhouse in 1999. Originating from Guatemala, plants exhibited yellowing, wilting, stunting, and bacterial oozing from the vascular tissues. Isolations on yeast dextrose-CaCO3 (YDC) and triphenyl-tetrazolium-chloride (TTC) agars resulted in off-white mucoid colonies and white, fluidal colonies with pink centers, respectively. Such colonies are typical of Ralstonia solanacearum (1). The disease was similar to a bacterial wilt of geranium caused by an unidentified biovar of R. solanacearum (3). Preliminary tests using Biolog MicroLog 3 (Hayward, Ca; 4.01A) and enzyme-linked immunosorbent assay (ELISA) (Agdia Inc., Elkhart, IN; BRA 33900/0500) identified the organism as R. solanacearum. For pathogenicity tests, a 10-μl droplet of water suspension containing 1 × 106 CFU of each of five geranium strains (PDA 22056-99, 81849-99, 81862-99, 51032-00, and 64054-00) per milliliter was placed on a stem wound made by cutting off the terminal growth of each of 4 6-leaf stage plants of geranium ‘Orbit Scarlet’, tomato ‘Rutgers’, potato ‘Russet Norkotah’, and eggplant ‘Black Beauty’ in a growth chamber at 28°C, 86% relative humidity, and 12 h light/dark cycle. Water was included as a control. The five strains caused severe yellowing and wilting within 10 days. Colonies typical of R. solanacearum were reisolated from symptomatic tissue on YDC and TTC. To determine the specific biovar, 20 pathogenic geranium strains from PA and DE plus a strain of R. solanacearum originally isolated from a geranium plant of Guatemalan origin received from Connecticut in 1995 were grown up to 28 days on Ayers mineral medium supplemented with a 1% final concentration of D-cellobiose, dextrose, meso-inositol, lactose, maltose, D-ribose, trehalose, mannitol, sorbitol, or dulcitol (1). Acid was produced by 21 test strains from the first five carbohydrates only. Such carbohydrate utilization is typical of bv 2 (1). Bv 2 identification was confirmed by real-time polymerase chain reaction using bv 2-specific primers and probes (N. Schaad, unpublished) designed from a bv 2-specific DNA fragment (2). All tested strains were positive using ELISA. In contrast, strains of bv 2 from geraniums in Wisconsin and South Dakota were reported to be negative using ELISA (4). From our results, it appears that bv 2 was introduced into the United States on geraniums from Guatemala in 1995 and 1999. This cool climate bv 2, a regulated agent by the Agricultural Bioterrorism Protection Act of 2002, has caused extensive crop loss in potatoes in Europe, but has not been found in potatoes in the United States.

Canola (Brassica napus) is a developing oleaginous crop grown commercially in Argentina, primarily in the southeastern region of Buenos Aires Province. Since 2002, plants exhibiting symptoms of wilt and xylem discoloration were observed in canola plants in experimental field plots located at the University of Buenos Aires, Buenos Aires, Argentina. Average disease incidence in 5- to 6-month-old canola cultivars developed in different countries was 18% (range = 9 to 27%). Disease symptoms that included yellowing, wilting, stunting, and necrosis of leaf tissue and suppressed root development appeared in irregular-shaped patches following the rows of plants. The first symptom observed was leaf yellowing followed by an irregular, brown necrosis of the leaf margins. Lesions coalesced to form large necrotic areas that led to severe defoliation beginning with the lower leaves. As the disease developed, a pale brown discoloration girdled the stems that progressed from the basal tissues to the apex. Affected plants were stunted and had small pods with no seeds. Diseased plants eventually collapsed and died. From June to July 2003, six samples consisting of five affected plants per sample were randomly collected from experimental field plots. Pieces (1 cm long) of disease basal stem tissue were thoroughly washed, surface sterilized in 1% sodium hypochlorite for 1 min, rinsed in sterile distilled water, blotted dry on sterile Whatman's filter paper, and incubated on potato dextrose agar in the dark at 26°C for 10 days. Ten resulting colonies were examined microscopically and identified as Fusarium oxysporum Schlechtend.:Fr. f. sp. conglutinans (Wollenweb.) W.C. Snyder & H.N.Hans. (3). Pathogenicity tests for three single-spore isolates of the fungus were performed on 6-week-old canola plants of cvs. Impulse, Master, Mistral, Monty, Rivette, and Trooper. Koch's postulates were completed for each isolate by dipping the roots of seedlings in a conidial suspension (2 times; 105 conidia per ml) for 15 min. Plants were repotted in a sterilized soil mix (soil/sand, 2:1). The experiment, which included five inoculated plants and three noninoculated (roots dipped in sterile distilled water) control plants for each cultivar, was conducted in a greenhouse at 23 to 25°C and 75% relative humidity with no supplemental light. Characteristic symptoms, identical to the original observations, developed within 14 days after inoculation on 100% of the inoculated plants for all three isolates. The pathogen was successfully reisolated from internal diseased stem tissue in all instances. Symptoms included stunted seedlings, leaf necrosis, and external stem discoloration. None of the control plants developed disease. The experiment was repeated once with similar results. F. oxysporum f. sp. conglutinans, which has been reported to cause disease in canola in Canada (1) and the United States (2), represents a serious threat to the main canola cultivars grown in Argentina. To our knowledge, this is the first report of canola wilt incited by F. oxysporum f. sp. conglutinans in Argentina. References: (1) D. Bernard et al. Can. Plant Dis. Surv. 81:102, 2001. (2) D. F.

The Penn State Cancer Initiative implemented LionVu 1.0 (Penn State University, United States) in 2017 as a web-based mapping tool to educate and inform public health professionals about the cancer burden in Pennsylvania and 28 counties in central Pennsylvania, locally known as the catchment area. The purpose of its improvement, LionVu 2.0, was to assist investigators answer person–place–time questions related to cancer and its risk factors by examining several data variables simultaneously. The primary objective of this study was to conduct a usability assessment of a prototype of LionVu 2.0 which included area- and point-based data. The assessment was conducted through an online survey; 10 individuals, most of whom had a masters or doctorate degree, completed the survey. Although most participants had a favorable view of LionVu 2.0, many had little to no experience with web mapping. Therefore, it was not surprising to learn that participants wanted short 10–15-minute training videos to be available with future releases, and a simplified user-interface that removes advanced functionality. One unexpected finding was the suggestion of using LionVu 2.0 for teaching and grant proposals. The usability study of the prototype of LionVu 2.0 provided important feedback for its future development.

This essay delineates the issues concerning AAPI art exhibitions from a curator’s perspective, particularly in response to the changing racial demographics and economics of the past decades. A discussion of practical, curatorial problems offers the reader an overview of the obstacles and reasons behind the lack of exhibitions of AAPI works in the United States. It is the author’s hope that by understanding the challenges particular to AAPI exhibitions, community leaders, and patrons will direct future financial support to appropriate museum operations, which in turn will encourage more exhibitions and research of the important artistic contribution of AAPI artists to American art.

ABSTRACT Four pollen diagrams from Maine, New York, and Pennsylvania provide fine resolution (40 or 80 years) records of vegetation change in northeastern United States during the past 2000 years. A long term increase in pollen accumulation rates (PAR) of Picea occurred at the three sites in Maine and New York. Around 1100 years ago, Tsuga and Fagus decreased and Quercus and Castanea increased at Ely Lake in northeastern Pennsylvania. Around 500 years ago, Tsuga and Fagus greatly decreased in Maine and northern New York, while in northeastern Pennsylvania there was an increase in Tsuga and Fagus and a decrease in Quercus and Castanea pollen. Non-arboreal PAR were negligible prior to the European settlement of the area, after which there was an abrupt increase in non-arboreal pollen types.

Western flower thrips, Frankliniella occidentalis (Pergande), originally distributed throughout western North America (Bryan and Smith 1956), have since spread to greenhouses in the eastern United States and Canada, and to many other parts of the world (Brodsgaard 1989). Populations have established outdoors in the southeastern United States (Chamberlin et al. 1992) and in several other warm regions of the world (Brodsgaard 1993). but have failed to establish in Ontario (Broadbent and Hunt 1991) and the northern parts of Europe (Brodsgaard 1993). We have not found reports of western flower thrips overwintering outdoors in the northeastern United States.

One of the few constants since the United States declared its independence is the presence of frequent financial crises with similar causes. In the nineteenth century, these panics were frequent with eight occurring over the century. However, following the Second World War there was a period of relative calm, which may have led to complacency. The Savings and Loans and the current financial crises have shown that these events remain a very real threat to economic stability. I have greatly benefitted from research assistance by Zach Winston from Pennsylvania State University and Gregory Kauffman from the University of Pennsylvania. (original abstract)

Greater Mexico refers both to the geographic region encompassing modern Mexico and its former territories in the United States, and to the Mexican cultural diaspora. Exhibitions of visual and material culture from greater Mexico have played an important role in articulating identities and affiliations that transcend limited definitions of citizenship. Following an introductory text by Jennifer Josten, five scholars offer firsthand insights into the intellectual, diplomatic, and logistical concerns underpinning key border-crossing exhibitions of the “NAFTA era.” Rubén Ortiz-Torres writes from his unique perspective as a Mexico City–based artist who began exhibiting in the United States in the late 1980s, and as a curator of recent exhibitions that highlight the existence of multiple Mexicos and Americas. Clara Bargellini reflects on a paradigm-shifting cross-border exhibition of the viceregal arts of the missions of northern New Spain. Kim N. Richter considers how the arts of ancient Mesoamerica and the Americas writ large figured within the Getty Foundation’s 2017 Pacific Standard Time: LA/LA initiative. Xóchitl M. Flores-Marcial offers insights into productive institutional collaborations with transnational Indigenous stakeholders, focusing on two recent Southern California exhibitions of the Oaxaca-based Tlacolulokos collective. Luis Vargas-Santiago discusses how Chicana/o/x art entered Mexico City’s Palacio de Bellas Artes in 2019 as a crucial component of an exhibition about how Mexican revolutionary Emiliano Zapata’s image has migrated through visual culture. Together, these texts demonstrate how exhibitions can act in the service of advancing more nuanced understandings of cultural and political interactions across greater Mexico.

Following the presentation of the American National Exhibition in Moscow in 1959, nine exhibits organized by the United States Information Agency traveled in the Soviet Union from 1961 to 1967. This article discusses the aims, preparation, content, and reception of these exhibits, which attracted more than five million visitors and provoked diverse reactions. The exhibitions and their guides served as a unique form of communication with Soviet citizens, informing them about U.S. achievements and freedoms and the American way of life. The initiatives offset Soviet Communist propaganda, advanced popular understanding of the United States, and promoted popular goodwill toward Americans. The low-key interactions between the guides and the visitors shed valuable light on the mindset and experiences of ordinary citizens in the USSR, who were a major target audience of these exhibitions, and also, more broadly, on U.S. public diplomacy during the Cold War.

This is a difficult book to review, because I am uncertain for whom it is intended. In 297 pages Philip Jenkins, Professor of History and Religious Studies at Pennsylvania State University, deftly and succinctly surveys the major bases of U.S. history--political, economic, social, and cultural developments. It is a small masterpiece of compression, and this, unfortunately, might be its weakness as far as high school and college classroom use is concerned. For students largely unfamiliar with this nation's history, the sweeping generalities encountered here will come across as just that, generalizations with no human flesh and blood attached.

AbstractThere has been—and continues to be—tension between Native peoples and museums in the United States due to past collecting practices and exhibitions that strive to interpret their culture and history without their involvement. Previously, many of these exhibitions stereotyped and lumped Native peoples together, depicting their cultures as static and interpreting them and their material culture from a Western scientific perspective. Changes are being made. Collaboration between Native peoples and museums in all areas of museum work, including exhibitions, is beginning to be considered by many as a best practice. Exhibitions developed in collaboration with Native peoples, with shared curatorial authority, decidedly help ease the historic tension between the two, and they are much more vibrant and accurate than when collaboration is lacking. This article will provide three examples of collaboration, defined with our tribal partners, to develop exhibitions at History Colorado, the state history museum, concluding with lessons learned.

This paper discusses attempts to popularize scientific knowledge about anthropology through exhibitions of natives in the United States and Brazil from the nineteenth century to the beginnings of the twentieth century. In the First Brazilian Anthropological Exposition (Rio de Janeiro, 1882), a group of Botocudos was characterized in a manner that can be related to the reification of the myth of the savage, an important part of the European culture that played a significant role in the construction of anthropological knowledge in the nineteenth century. From the analyses of such exhibitions, we derive implications for science popularization and education, concerning the ideological undertones of scientific knowledge.

BACKGROUND: The number of organs available for transplantation in the United States is insufficient, and the donor rate in New Jersey is particularly low. OBJECTIVES: To explore reasons nurses do or do not refer organ donors and to identify factors that contribute to differences in referral rates in New Jersey and Pennsylvania. METHODS: Registered nurses (N = 976) in 57 nongovernmental acute care hospitals, primarily in emergency departments and intensive care units, completed a questionnaire that focused on their knowledge and participation in the organ procurement process. RESULTS: Two-thirds of the subjects said they had participated in organ procurement. Pennsylvania nurses had a significantly higher involvement rate than New Jersey nurses. Pennsylvania nurses were also slightly more knowledgeable about the process. A higher proportion of nurses in both states who attended continuing education programs participated. CONCLUSIONS: Nurses need more inservice education regarding policies and procedures for organ donation.

Abstract The article discusses the recent international interest in contemporary Romanian art and its growth in market share, with a focus on the United States. The theme is followed thorough in numerous museum exhibitions, increased collector following, art fair presence, gallery representation and auction activity initially in Europe and the United States. The phenomenon is discussed both in the context of the larger international movement conducive to the contemporary art price bubble, and in that of the local socio-economic changes. My chief interest lies in the factors leading up to the entry of post 1989 Romanian art in the global arena as a manifestation of market forces in the field. The analysis follows its grass roots local emergence through non-profit institutions, individual artists, small publications, low budget galleries, as well as the lack of contribution (with few notable exceptions) of state institutions, while pointing out the national context of increasing deregulation of social support systems resulting in lack of focus on cultural manifestations. The conclusion is that the recent ascent of contemporary Romanian art (and coincidentally, the award winning contemporary Romanian cinematography) is a fortuitous convergence of various factors, among which, increased international mobility and sharing. At the same time, it is also the result of the evolution of various individual artists that pursued a form of art rooted in Romanian artistic tradition but with a focus on the symbolic figurative. The result is a personal semiotics of raising the mundane to extraordinary levels that reconfigured the anxiety of entering a new system into an unmistakable and lasting visual language.

Pennsylvania is the largest producer of shale gas in the United States and is the second-largest natural gas-producing state overall. Owing to its strategic location atop the Marcellus and Utica Shale Formations, Pennsylvania’s position as a major natural gas producer is relatively new. Just a little over a decade ago, Pennsylvania ranked sixteenth among states in total natural gas production. With this rapid rise in the amount of natural gas development, there has been a corresponding increase in activity in courtrooms across Pennsylvania—both in state and federal courts. As a result, Pennsylvania oil and gas law has evolved within a number of different legal areas, with leasing and title issues perhaps being among the most frequent—and most important—topics that have been addressed by courts. This survey will address the 2019 reported judicial opinions issued by state courts in Pennsylvania that address oil and gas leasing and title issues.

ABSTRACT A team, consisting of the United States Environmental Protection Agency; Pennsylvania Department of Environmental Protection; Pennsylvania Department of Health; Agency for Toxic Substances and Disease Registry; United States Coast Guard and United States Army Corps of Engineers, has completed major steps to provide a safe and healthy environment for the residents of Laurel Gardens, Hazleton, PA. What started as a simple underground gasoline leak took on more serious dimensions when gasoline vapors were found in nearby homes. The investigation and mitigation expanded to include over 400 properties. The remediation consists of a ground water treatment system and a soil vapor extraction system. This paper and its presenters look at the critical aspects of this case as the investigation went from subsurface soil and ground water contamination impacting surface water to the contamination of indoor air. It examines the impact of preferential pathways that include sanitary and storm sewers as well as a 19th century abandoned coal mine. In addition to the technical aspects, this examination looks at the public health and community issues that have surrounded this case.

Polish modern art was collected by leading figures within America's cultural vanguard. Most prized the art's stylistic innovation; they were likely unaware of the ideological charge that animated modernism's makers. By the end of the 1930s, numerous exhibitions of Polish art had been mounted in the United States; however, few concentrated on strikingly innovative works, preferring instead traditional themes, genres, and styles. Nonetheless, Poland's modernist efforts garnered popular success at the New York World's Fair of 1939. The modern art from other central and eastern European nations was actively promoted by its makers, who had immigrated to the United States. Poland's modern art did not benefit from a similar presence, its modernists having mostly elected to remain in their native land. The paucity of Polish artists in 1930s America compromised their chance to exercise an influential role just as the United States was consolidating an international canon of modern art.

After the #MeToo movement kicked off in the United States in 2018, it found its way to China and has triggered a number of exhibition projects around the country, organized by young activists, artists and curators, which have galvanized transnational feminist exchanges in the past few years. The article analyses exhibitions such as The Voiceless Rise Up: #MeToo in China, Her Story: Eliminating Gender Violence 2020, Above Ground: 40 Moments of Transformation and Stand by Her, which consisted of works documenting sexual assault and the #MeToo movement in China, as well as of artworks that are dealing with issues concerning sexual assault, the One Child Policy, motherhood, queerness and empowerment. These exhibitions and the #MeToo movement, respectively, demonstrate a growing transnational interconnectedness among activists fighting towards common feminist goals. What is more, these exhibitions are under constant scrutiny and fear of being cancelled, which is evidence of an exhaustive struggle for the official acceptance of women’s rights and ‘radical’ artworks. This article gives an overview of these projects, their transnational interconnectedness, as well as their perception and reaction of the general public, the press and censors. The article argues for a shift from women-centred exhibitions to exhibitions with a strong activist/feminist agenda that are also part of an unprecedented transnational framework.

Salmonella enterica subspecies entericaserotype Dublin (S. enterica Dublin) emerged for the first time in New York, Pennsylvania, and Ohio in 1988. Since that time this host-adapted serotype has spread throughout the veal- and dairy beef-raising operations in the region; very few dairy farms have experienced clinical S. enterica Dublin infections. This study details the epidemiology of the outbreaks in cattle. During the period 1988 through 1995, nine New York and four Pennsylvania counties have been affected; 13 different locations were involved in New York, and 10 were involved in Pennsylvania. The morbidity and mortality and seasonal distribution of outbreaks, which totaled 35, is described. The antimicrobial susceptibility pattern of isolates revealed that many of the strains were resistant to a number of commonly used drugs. Clinical case details and pathology information are provided, with a caution to clinicians and microbiologists presented with suspect animals, i.e., most cases occurred in older calves, which is atypical for salmonellosis for this region (calves were 8 or more weeks old) and presented as pneumonia and septicemia rather than the primarily diarrheal syndrome that is more typically recognized for the region. The epidemiology of cases is analyzed through cluster analysis of bacterial isolates and their fatty acid methyl ester profiles; at least six clones appeared in the region during the study period. Results of the epidemiology analysis are used to support a hypothesis regarding the source of S. enterica Dublin for the region and its manner of dissemination.

Abstract The activities of Mexican banker and hacendado Zeferino Dominguez in the early twentieth century raise questions about the assumption that Mexico was merely the beneficiary of modern agricultural science developed in the United States. Dominguez was a banker and large landowner who turned his haciendas into private agricultural experiment stations, conducting research on better methods of growing corn, cotton, wheat, and beans with the labor of his peones. He shared his results through lecture tours and published works in Mexico and traveled extensively in the United States, speaking to groups of farmers and agricultural scientists about his methods of dry farming and corn propagation. He exhibited at agricultural fairs and exhibitions, attended Farmers’s Institutes and conferences, and published a manual for use by average American farmers. Like many agricultural reformers in the United States, he addressed the problems of rural poverty and land concentration not with socialism, but with visions of a Mexico filled with small, capitalistic, home-owning farmers producing with scientific methods and business efficiency.

This article examines conflicting racial, archaeological and art historical interpretations of Olmec art produced in the United States in the early 1960s. It inscribes shifting approaches to the study of monumental Olmec art by figures like George Kubler within the contexts of violent modernization of the Olmec ‘heartland’ of Veracruz and Tabasco, the politicized display of this artistic tradition in museums and traveling exhibitions, and the unstable horizons of U.S.-Mexico diplomatic relations during that period.

AbstractThis article reconstructs the 19th century history of events regarding a few female wax anatomical models made in Florence. More or less faithful copies of those housed in Florence's Museum of Physics and Natural History, these models were destined for display in temporary exhibitions. In their travels through Europe and the United States, they transformed the expression "Florentine Venus" into a sort of brand name used to label and offer respectability to pieces of widely varying quality.

During the late eighteenth and early nineteenth century, Great Britain utilized its extensive coal reserves to emerge as the world's leading industrial power. “If a patch of a few square miles has done so much for central England,” one British writer pondered in 1856, “what may fields containing many hundred square leagues do for the United States?” In the story of American coal, the two most important states on the eve of the nineteenth century were Virginia and Pennsylvania. Virginia was endowed with bituminous coal reserves in both the James River Basin and its western counties, while Pennsylvania enjoyed a virtual monopoly on American anthracite coal as well as a massive bituminous region west of the Allegheny Mountains.

Most agricultural output in the northeastern United States comes from counties that have experienced significant development. A mail survey, with 300 responses, was conducted in southeastern Pennsylvania to determine farmer adaptation to urbanization in this region. Despite development, traditional agriculture still predominates. Changes in land use were examined using multinomial logit models. Results show that changes in population density and farm preservation policies have an influence, as increased population density reduced total land operated and having land in an agricultural security area increased it. Both differential assessment and agricultural security areas increased the cultivation of traditional, land extensive crops.

Checklists provide information about the species found in a defined region and serve as baselines for detecting species range expansions, contractions, or introductions. Bees are a diverse and important group of insect pollinators. Although some bee populations are declining, these patterns are difficult to document and generalize due to a lack of long-term studies for most localities. Documenting the diversity of wild bee communities is critical for assessing pollination services, community ecology, and geographical and temporal changes in distribution and density. Here, an updated checklist of the bees of the Commonwealth of Pennsylvania, USA, is presented. Since the first checklist was published (2010; 372 species), thousands of additional specimens from the state have been collected and databased, new species have been described in the region, and the taxonomic status of some species have changed. Specimen data from insect collections, databases, scientific literature, and unpublished records were compared to the original checklist. Seventy-nine new state species records – including 49 first-time reports – representing five of the six bee families in North America, were documented resulting in a total of at least 437 bee species reported from Pennsylvania. We highlight new county records and species persistence details. Our list includes a total of 23 exotic species and at least five species of conservation concern. Lists of species excluded from the state checklist and species anticipated to occur in Pennsylvania are also included. This checklist provides baseline data for researchers and the public. The benefits of insect collections, specimen databases, determination and voucher labels, and georeferencing to biodiversity studies and other aspects of biological research are also discussed.

Hydrophobic particle film technology (HPF) is a developing pest control system for tree fruit production systems. Studies were established in Chile, and Washington, Pennsylvania, and West Virginia in the United States, to evaluate the effect of HPF technology on tree fruit yield and quality. Studies in Chile, Washington, and West Virginia demonstrated increased photosynthetic rate at the leaf level. Yield was increased in peaches (Chile) and apples (West Virginia), and fruit size was increased in apples (Washington and Pennsylvania). Increased red color in apple was demonstrated at all sites with reduced russetting and `Stayman' cracking in Pennsylvania. HPF technology appears to be an effective tool in reducing water and heat stress in tree fruit resulting in increased fruit quality.
