Helianthus verticillatus Small (whorled sunflower) is a federally endangered plant species found only in the southeastern United States that has potential horticultural value. Evidence suggests that H. verticillatus is self-incompatible and reliant on insect pollination for seed production. However, the identity of probable pollinators is unknown. Floral visitors were collected and identified during Sept. 2017 and Sept. 2018. Thirty-six species of visitors, including 25 hymenopterans, 7 dipterans, 2 lepidopterans, and 2 other insect species, were captured during 7 collection days at a site in Georgia (1 day) and 2 locations in Tennessee (6 days). Within a collection day (0745–1815 hr), there were either five or six discrete half-hour collection periods when insects were captured. Insect visitor activity peaked during the 1145–1215 and 1345–1415 hr periods, and activity was least during the 0745–0845 and 0945–1015 hr periods at all three locations. Visitors were identified by genus and/or species with morphological keys and sequences of the cox-1 mitochondrial gene. The most frequent visitors at all sites were Bombus spp. (bumblebees); Ceratina calcarata (a small carpenter bee species) and members of the halictid bee tribe Augochlorini were the second and third most common visitors at the two Tennessee locations. Helianthus pollen on visitors was identified by microscopic observations and via direct polymerase chain reaction of DNA using Helianthus-specific microsatellites primers. Pollen grains were collected from the most frequent visitors and Apis mellifera (honeybee) and counted using a hemocytometer. Based on the frequency of the insects collected across the three sites and on the mean number of pollen grains carried on the body of the insects, Bombus spp., Halictus ligatus (sweat bee), Agapostemon spp., and Lasioglossum/Dialictus spp., collectively, are the most probable primary pollinators of H. verticillatus.

This chapter surveys scholarly writing about the intersection of religion and sport in the United States and Britain. It reviews the dominant historiography of works on religion and athletics, arguing that historians have focused primarily on clergy within Protestant traditions and the question of whether specific sports were considered licit or illicit in different places and times. This perspective occludes consideration of Catholic and other religions, the historical importance of bloodsport, and the informal nature of the interrelationship of religion and sport in daily life. The chapter also examines approaches to sport in scholarship from religious studies, highlighting the ways that scholars of religion have imagined sport as a form of religion (or “natural religion,” civil religion), often taking the perspective of the spectator and fan. The chapter concludes by exploring newer modes of analysis that explore the body as a site where religion and sport intersect.

Deaths In Custody

Paul Alphonse, a 67 year-old Aboriginal died in hospital while in police custody. A significant contributing factor to his death was that he was stomped on so hard that there was a boot print on his chest and several ribs were broken. His family alleged police brutality. The inquest into the death of Paul Alphonse offers an opportunity to explore the contemporary relationship between Aboriginal people and Canadian society and, significantly, how law operates as a site for managing that relationship. I suggest that we consider the boot print on Alphonse's chest and its significance at the inquest in these two different ways. First, although it cannot be traced to the boot of the arresting officer, we can examine the boot print as an event around which swirls Aboriginal/police relations in Williams Lake, both the specific relation between the arresting officer and Alphonse, and the wider relations between the Aboriginal community and the police. Second, the response to the boot print at the inquest sheds light on how law is a site for obscuring the violence in Aboriginal people's lives. A boot print on the chest of an Aboriginal man, a clear sign of violence, comes to mean little because Aboriginal bodies are considered violable – both prone to violence, and bodies that can be violated with impunity. Law, in this instance in the form of an inquest, stages Aboriginal abjection, installing Aboriginal bodies as too damaged to be helped and, simultaneously to harm. In this sense, the Aboriginal body is homo sacer, the body that maybe killed but not murdered. I propose that the construction of the Aboriginal body as inherently violable is required in order for settlers to become owners of the land.

Federal Sentencing

In federal criminal cases, federal law requires that judges consider the sentences other courts have imposed in factually similar matters. Courts and parties, however, face significant challenges in finding applicable sentencing precedents because judges do not typically issue written sentencing opinions, and transcripts of sentencings are not readily available in advanced searchable databases. At the same time, particularly since the Supreme Court’s 2005 decision in United States v. Booker, sentencing precedent has come to play a significant role in federal sentencing proceedings. By way of example, this article discusses recent cases involving defendants with gambling addictions, and recent cases involving college admissions or testing fraud. The article explores the ways the parties in those cases have used sentencing precedent in their advocacy, as well as the ways the courts involved have used sentencing precedent to justify their decisions. Given the important role of sentencing precedent in federal criminal cases, the article finally looks at ways in which the body of sentencing law could be made more readily available to parties and courts alike.

Embodied Practice

This article examined attitudes, knowledge, behavior and practices of men and society on Gender bias in sports. The paper examined how the African female body was made into an object of contest between African patriarchy and the colonial system and also shows how the battle for the female body eventually extended into the sporting field. It also explored the postcolonial period and the effects on Zimbabwean society of the colonial ideals of the Victorian culture of morality. The study focused on school sports and the participation of the girl child in sports such as netball, volleyball and football. Reference was made to other sports but emphasis was given to where women were affected. It is in this case where reference to the senior women soccer team was made to provide a case study for purposes of illustration. Selected rural community and urban schools were served as case references for ethnographic accounts which provided the qualitative data used in the analysis. In terms of methodology and theoretical framework, the paper adopted the political economy of the female body as an analytical viewing point in order to examine the body of the girl child and of women in action on the sporting field in Zimbabwe. In this context, the female body is viewed as deeply contested and as a medium that functions as a site for the redirection, profusion and transvaluation of gender ideals. Using the concept of embodiment, involving demeanor, body shape and perceptions of the female body in its social context, the paper attempted to establish a connection between gender ideologies and embodied practice. The results of the study showed the prevalence of condescending attitudes towards girls and women participation in sports.

Background: Fibromyalgia syndrome (FMS) is a chronic disease characterized by widespread body pain, weakness in certain parts of the body (critical points), low pain tolerance, sleep disturbances, and fatigue. This syndrome is considered rare in Jordan. Objectives: The research aimed to find out the association of the angiotensin converting enzyme, methylenetetrahydrofolate reductase, and vitamin D receptor (ACE, MHFTR, and VDR, respectively) genotypes with FMS among Jordanian patients. Methods: This work included 22 FM patients and 22 healthy individuals of Jordanian Arabic origin. The ACE rs4646994, MTHFR rs1801133, and VDR rs2228570 genotypes were determined using polymerase chain reaction (PCR) followed by restriction fragment length polymorphism. Results: No associations between ACE rs4646994, MTHFR rs1801133, and VDR rs2228570 with the vulnerability of a person for the development of FMS were found. However, we found an association between the ACE rs4646994 genotype and restless leg among FM patients. Conclusion: Based on result from this study, it appears that the ACE rs4646994 genotype is associated with restless leg among FMS patients of Jordanian origin. Further clinical investigations with larger sample sizes are required to confirm these findings and to understand the molecular mechanism of ACE rs4646994 genetic variant in the restless leg syndrome among FM patients.

ABSTRACT The I-R element at the R locus destabilizes kernel pigmentation giving the variegated pattern known as stippled (R-st). In trans linkage phase with R-st the element was shown to act as a modifier of stippled, intensifying seed spotting in parallel with effects of the dominant linked modifier M-st. Presence of I-R in the genome was, therefore, shown to be detectable as a modifier of R-st. When this test was used, new modifiers resembling M-st were often detected following mutations of R-st to the stable allele R-sc. Such mutations evidently occurred by transposition of I-R away from the R locus to a site where it was identifiable as a modifier. M-st may be such a transposed I-R. Analysis of mutations to R-sc during the second (sperm-forming) mitosis in pollen grains showed that some of the transposed I-R elements were linked with R, whereas others assorted independently. Their strengths varied from barely discernible to a level equal to M-st. Overreplication frequently accompanied transposition at the sperm-forming mitosis, leading to transposed I-R elements in both the mutant and nonmutant sperm.

Mitochondrial Genome Diversity

Abstract We examined mitochondrial DNA polymorphisms via the analysis of restriction fragment length polymorphisms in three closely related species of pines from western North America: knobcone (Pinus attenuata Lemm.), Monterey (P. radiata D. Don), and bishop (P. muricata D. Don). A total of 343 trees derived from 13 populations were analyzed using 13 homologous mitochondrial gene probes amplified from three species by polymerase chain reaction. Twenty-eight distinct mitochondrial DNA haplotypes were detected and no common haplotypes were found among the species. All three species showed limited variability within populations, but strong differentiation among populations. Based on haplotype frequencies, genetic diversity within populations (HS) averaged 0.22, and population differentiation (GST and θ) exceeded 0.78. Analysis of molecular variance also revealed that >90% of the variation resided among populations. For the purposes of genetic conservation and breeding programs, species and populations could be readily distinguished by unique haplotypes, often using the combination of only a few probes. Neighbor-joining phenograms, however, strongly disagreed with those based on allozymes, chloroplast DNA, and morphological traits. Thus, despite its diagnostic haplotypes, the genome appears to evolve via the rearrangement of multiple, convergent subgenomic domains.

How to inculcate virtue in the citizens of Magnesia by means of the dance component of choreia constitutes one of the principal concerns in the Laws (= Leg.), revealing Plato's evolving ideas about the expediency of music and paideia for the construction of his ideal city since the Republic. Indeed, a steady stream of monographs and articles on the Laws has enriched our understanding of how Plato theorizes the body as a site of intervention and choral dance as instrumental in solidifying social relations and in conditioning the ethical and political self. As one scholar has aptly put it: ‘a city and its sociopolitical character [are] effectively danced into existence.’ Drawing on this recent work, I focus on an enigmatic passage in Laws Book 7 that merits more attention than it has received, in which Plato curiously singles out Bacchic dances from those that are ‘without controversy’ (815b7–d4): τὴν τοίνυν ἀμφισβητουμένην ὄρχησιν δεῖ πρῶτον χωρὶς τῆς ἀναμφισβητήτου διατεμεῖν. τίς οὖν αὕτη, καὶ πῇ δεῖ χωρὶς τέμνειν ἑκατέραν; ὅση μὲν βακχεία τ᾽ ἐστὶν καὶ τῶν ταύταις ἑπομένων, ἃς Νύμφας τε καὶ Πᾶνας καὶ Σειληνοὺς καὶ Σατύρους ἐπονομάζοντες, ὥς φασιν, μιμοῦνται κατῳνωμένους, περὶ καθαρμούς τε καὶ τελετάς τινας ἀποτελούντων, σύμπαν τοῦτο τῆς ὀρχήσεως τὸ γένος οὔθ᾽ ὡς εἰρηνικὸν οὔθ᾽ ὡς πολεμικὸν οὔθ᾽ ὅτι ποτὲ βούλεται ῥᾴδιον ἀφορίσασθαι: διορίσασθαι μήν μοι ταύτῃ δοκεῖ σχεδὸν ὀρθότατον αὐτὸ εἶναι, χωρὶς μὲν πολεμικοῦ, χωρὶς δὲ εἰρηνικοῦ θέντας, εἰπεῖν ὡς οὐκ ἔστι πολιτικὸν τοῦτο τῆς ὀρχήσεως τὸ γένος, ἐνταῦθα δὲ κείμενον ἐάσαντας κεῖσθαι, νῦν ἐπὶ τὸ πολεμικὸν ἅμα καὶ εἰρηνικὸν ὡς ἀναμφισβητήτως ἡμέτερον ὂν ἐπανιέναι. So, first of all, we should separate questionable dancing far from dancing that is without controversy. Which is the controversial kind, and how are the two to be distinguished? All the dancing that is of a Bacchic kind and cultivated by those who indulge in intoxicated imitations of Nymphs, Pans, Sileni and Satyrs (as they name them), when performing certain rites of expiation and initiation—this entire class of dancing cannot easily be marked off either as pacific or as warlike, nor as of any one particular kind. The most correct way of defining it appears to me to be this—to place it away from both pacific and warlike dancing, and to pronounce that this type of dancing is οὐ πολιτικόν; having thus set aside and dismissed it, we will now return to the warlike and pacific types, which without controversy belong to us.
