Disproportionate Relative Importance of a Terrestrial Beetle Family (Coleoptera: Scarabaeidae) as a Prey Source for Central Appalachian Brook Trout
Authors: Utz Ryan M. , Ratcliffe Brett C. , Moore Brett T. , Hartman Kyle J. 
Published: February 2007

AbstractBrook trout Salvelinus fontinalis and other salmonids in Appalachia typically inhabit headwater watersheds, where food resources may limit growth. We monitored the feeding trends of a brook trout population in central Appalachia over the course of 2 years to determine variation in feeding intensity and important prey items. One terrestrial beetle family, Scarabaeidae, provided a disproportionate amount of energy during the only time of year when brook trout were feeding substantially above maintenance ration. Scarab beetles contributed 39.6% of all energy consumed during May and June of both years, though the number of fish with one or more scarabaeids present in the stomach varied by month (22.2–51.7%). The species composition of scarab beetles consumed suggested that four species are of particular importance. Our findings imply that scarabaeids represent a considerably important prey taxon for brook trout in the region. Considering the foraging habits of the scarabaeid species in question, the phenomenon we witnessed probably occurs throughout Appalachia.
The Trianon and On: Reading Mass Social Dancing in the 1930s and 1940s in Alberta, Canada
Authors: Doolittle Lisa 
Published: February 2007

Every Friday and Saturday night during the 1930s and 1940s in southern Alberta everybody danced, or so the story goes. And that is about as far as “the story” goes. Serious considerations of popular dancing are largely absent from existing historical records of this time and place, despite the apparent omnipresence of dancing in so many people's lives. Social dancing happened on a large scale at a pivotal time for community formation in Canada's West, when profound social changes occurred as the Depression gave way to World War II. What was going on besides and through and because of all that dancing? And how to investigate such an ephemeral phenomenon?Today, I can still stand in the Trianon Ballroom in Lethbridge, Alberta's third largest city and the center of the region I will discuss here. The Trianon first opened its doors as a dance hall in 1931 and ceased operating in 1961. In the 1930s and 1940s literally hundreds of little Trianon-like halls graced small Canadian prairie towns, although most of these dance halls have since disappeared. In Lethbridge alone, four major dancing establishments were packed with patrons dancing to live bands on as many as three nights a week, the YMCA offered hostess dances for military personnel, the Kiwanis club gave teen dances every Friday night, and one could dance at the Masonic Hall and in local hotels (Viel 1998, 24).
Dancing in the Past, Living in the Present: Nostalgia and Race in Southern California Neo-Swing Dance Culture
Authors: Usner Eric Martin 
Published: February 2007

Nostalgia is a revisionary act, emptying history of depth and texture, when having a manageable history is contingent on accumulation of time-trapped stuff. It's what people hold to, release into play, invent from, use for amusement and amazement, it's what and how people define their passage, their commonality and distinctiveness; a faith, a system of belief expressed in accumulated tokens and artifacts; a culture nourished on mythological narratives and seasonal events, by the passing of gods and goddesses, by stacks of packaged time renewed in changing formats; it's generality so resolutely particular to each adherent that often only myth and liturgy can serve as neutral rites of discourse. It's obviously the faith love invents to reassure its durability; a radical theology, a fusion of intensified sacred and secular yearnings and desires.“Pre-Ramble” to Reading Jazz, David Meltzer (1993, 34)
Performative Power in Native America: Powwow Dancing
Authors: Axtmann Ann 
Published: February 2007

Back in 1988, my father had passed away and for a short time I stopped dancing. I lost interest, I lost my heart, you know…' cause I used to dance on stage for my father…Recently,…I just started back dancing…the reason is 'cause…This is me. This is who I am. A dancer. A Fancy dancer at that. And this is where I felt my father was most proud of me. And even now, I still feel that he is most proud of me. Right now, he's with me when I dance and I dance for my father. I dance for him, for my pop, for Gray Fox.—Calvin Burns (Cherokee) (Traveling the Distance)Throughout the United States and Canada people go to Native American intertribal powwows. At powwows women, men, and children execute rhythmic movement, drumming, and song as they experience and express sensory stimuli. The aroma of sage incense pervades as Indians and non-Indians socialize, share fry bread, and sell, buy, or “window shop” at concession stands. Vendors display T-shirts, fur, turquoise, silver, and beaded jewelry as well as artwork, CDs, and Ecuadorian and Peruvian items. All participants enjoy storytelling, comedy skits, Indian rap and country music performances, and Mexican “Aztec” dance presentations alongside rituals such as giveaways, the Eagle ceremony, or the Veterans dance. These social and spiritual celebrations occur in increasing numbers across North America. In the tristate region of New York, New Jersey, and Connecticut alone, from 1995 to 2001, the number of powwow events has tripled.
Dialogue in Dance Studies Research
Authors: Dils Ann , Crosby Jill Flanders 
Published: February 2007

In writing this paper, we—Jill Crosby and Ann Dils—render into text six years of sporadic dialogues. Through our explanation and examination of the 1994 movement analysis and description project that began our exchanges and discussion of subsequent readings, we hope to explore important aspects of dance studies research. Our use and understanding of Laban-based movement analysis as a tool for understanding movement as it is felt and observed, awareness of concepts of dialogue and the dialogical process as potential frameworks, critical lenses, and theoretical bases for dance studies research, and adaptation of the interpretive paradigm to suit dance research are especially important to this exploration. Little of our text is written in dialogue form (Crosby:, Dils:); rather, we hope, by drawing examples from our project, Crosby's dissertation, and the works of other researchers, to capture the bubbling-up of understanding that stems from the cooperative and confrontational exchanges of dance studies research.Over a three-month period in 1994, we conducted a movement analysis and description project as part of Crosby's work for her doctoral dissertation, “Will the Real Jazz Dance Please Stand Up? A Critical Examination of the Roots and Essence of Jazz Dance with Implications for Education.” Crosby investigated the aesthetic shapings of jazz expression inclusive of its West African roots from a cross-disciplinary perspective, using ethnographic methods as tools for understanding artistic form (Crosby 1995). An arts educator and dancer, Crosby wanted to establish a pool of descriptive and potentially inherent characteristics for music-based jazz dance. These characteristics would comprise a personal definition for the form and provide Crosby with a point of departure for a discussion of jazz as a movement tradition.
Mediterranean climate effects. I. Conifer water use across a Sierra Nevada ecotone
Authors: Royce E. B. , Barbour M. G. 
Published: February 2007

Xylem water potential of the midelevation conifersPinus jeffreyi, Pinus lambertiana, Abies concolor, andCalocedrus decurrens, the higher elevationPinus monticolaandAbies magnifica, and co‐occurring evergreen angiosperm shrubs, together with soil moisture under these plants, were monitored at three sites on the Kern Plateau in the southernmost Sierra Nevada Range of California. Site locations spanned the ecotone between the mid‐ and upper montane forests at elevations of 2230–2820 m. Measurements were made through a low‐snowfall year and a heavy‐snowfall year.In the Mediterranean climate of the Sierra Nevada, the heavy winter snowpack persists into late spring, after precipitation has effectively stopped. We found the subsequent depletion of soil moisture due to plant water uptake to result in predawn xylem water potentials for conifers more negative by 0.6–1.4 MPa than those for shrubs or inferred soil potentials. Shrubs generally depleted soil moisture more rapidly and ultimately extracted a greater fraction of the available soil moisture than did the conifers. This depletion of soil moisture by shrubs, particularlyArctostaphylos patula, may limit conifer growth and regeneration by prematurely terminating growth on the shallow soils studied. The conifers all generally showed similar patterns of soil moisture use, except thatA. magnificaextracted moisture more rapidly early in the season.
Collisions, Prohibitions, and the Admiralty Court in Seventeenth-Century London
Authors: Steckley George F. 
Published: February 2007

When Anthonis Van den Wyngaerde executed his sweeping panorama of London in 1543, he drew some two dozen ships in the Thames, but only four of them downstream from St. Katherine's Dock. A century later, however, Wenceslaus Hollar carefully represented well over a hundred seagoing vessels in a ribbon of masts winding down river as far as the eye could see. By the 1650s a mariner noted the difficulty of navigating the Thames at low tide, especially during “mackerel time,” and Admiralty Judges at Doctors' Commons near St. Paul's were hearing complaints that congestion in the river was endangering London's environment. Petitioners alleged in 1658 that Jenkin Ellis, a shoemaker and wharf owner, had so exploited his foothold of just ten yards along the north shore of the river, by selling permission to anchor ships eight-and ten-abreast, that the entire bank from St. Katherine's Stairs to the Dock was ruined. It had once been, said witnesses, a “fair sandy ground” where “people might pass on foot,” where watermen could “wax and tallow their boats.” But after Ellis had arrived in 1640, the bank slowly turned to “mud…ooze and dirt,” and “the current of the Thames near shore” where the ships lay was now so “hindered…that if not timely prevented,” the river would be “choked up.” Fires carelessly tended aboard the ships when they were grounded at low tide threatened houses in the entire precinct. When riding at anchor near the shoemaker's wharf, the vessels forced lightermen to row in midriver “against the strength and current of the tide.”The rising number of ships in English waterways had apparently reduced everyone's margin for error in the seventeenth century. For collisions in the Thames and elsewhere were providing the civil lawyers of London's Admiralty Court with a stream of cases. Ironically, this litigation, it is argued here, reveals both the resourcefulness of England's maritime judges and the major cause of a decline in their authority during the late Stuart decades.
Glacial survival ortabula rasa? The history of North Atlantic biota revisited

Published: February 2007

AbstractUp to the 1960s, there was nearly complete consensus that disjunctions and endemism in the North Atlantic cannot be explained withoutin situsurvival during the glaciations (the "nunatak hypothesis"). The alternative "tabula rasahypothesis" of postglacial immigration was regarded to be of merely historical interest. Herein we review recent geological, molecular, taxonomic, and biogeographic data to re‐examine this view. There is now strong geological evidence for some ice‐free North Atlantic areas within the maximum limits of the Late Weichselian/Wisconsian ice sheets, but no fossils have been found to prove continuousin situexistence of life in these areas. Molecular data suggest that many plants and animals have migrated recently across the Atlantic, even if they lack mechanisms promoting long‐distance dispersal. In other species, there are deep trans‐oceanic phylogeographic splits suggesting survival in two or more refugia, but these refugia may have been located outside the ice sheets. For vascular plants, we provide an updated list of 77 north boreal, alpine, and arctic taxa accepted as North Atlantic endemics. The degree of endemism is very low (0.0‐1.9% single‐region endemism). Forty endemics occur in more than one of the isolated Atlantic regions, indicating extensive migration and complicating inferences on the location of refugia. Thirty‐four endemics are probably not hardy enough for nunatak survival and are explained by postglacial immigration (orin situevolution). Among the 43 "hardy" endemics, there is not a single outcrossing diploid that could suggest long‐term evolution. Most of the hardy endemics are asexual or self‐fertilizing polyploids, some of postglacial hybrid origin. Others are preglacial polyploids which immigrated postglacially or survivedin situ. Some ice‐free areas, such as the extensive Greenlandic ones, may have supported survival of some hardy organisms. The evidence accumulated since the 1960s suggests, however, that endemism and disjunctions in the North Atlantic can be explained without invokingin situglacial survival.

ImportanceExcess opioid prescribing after surgery can result in prolonged use and diversion. Email feedback based on social norms may reduce the number of pills prescribed.ObjectiveTo assess the effectiveness of 2 social norm-based interventions on reducing guideline-discordant opioid prescribing after surgery.Design, Setting, and ParticipantsThis cluster randomized clinical trial conducted at a large health care delivery system in northern California between October 2021 and October 2022 included general, obstetric/gynecologic, and orthopedic surgeons with patients aged 18 years or older discharged to home with an oral opioid prescription.InterventionsIn 19 hospitals, 3 surgical specialties (general, orthopedic, and obstetric/gynecologic) were randomly assigned to a control group or 1 of 2 interventions. The guidelines intervention provided email feedback to surgeons on opioid prescribing relative to institutionally endorsed guidelines; the peer comparison intervention provided email feedback on opioid prescribing relative to that of peer surgeons. Emails were sent to surgeons with at least 2 guideline-discordant prescriptions in the previous month. The control group had no intervention.Main Outcome and MeasuresThe probability that a discharged patient was prescribed a quantity of opioids above the guideline for the respective procedure during the 12 intervention months.ResultsThere were 38 235 patients discharged from 640 surgeons during the 12-month intervention period. Control-group surgeons prescribed above guidelines 36.8% of the time during the intervention period compared with 27.5% and 25.4% among surgeons in the peer comparison and guidelines arms, respectively. In adjusted models, the peer comparison intervention reduced guideline-discordant prescribing by 5.8 percentage points (95% CI, −10.5 to −1.1; P = .03) and the guidelines intervention reduced it by 4.7 percentage points (95% CI, −9.4 to −0.1; P = .05). Effects were driven by surgeons who performed more surgeries and had more guideline-discordant prescribing at baseline. There was no significant difference between interventions.Conclusions and RelevanceIn this cluster randomized clinical trial, email feedback based on either guidelines or peer comparison reduced opioid prescribing after surgery. Guideline-based feedback was as effective as peer comparison-based feedback. These interventions are simple, low-cost, and scalable, and may reduce downstream opioid misuse.Trial RegistrationClinicalTrials.gov NCT05070338
Machine Learning Application to Optimize Spent Mushroom Compost (SMC) Biochar as Filter Media for Heavy Metal Adsorption in Abandoned Mine Water

AbstractThe surging global population strains resources, escalating pollution, and exacerbating water scarcity. Sustainable water management necessitates alternative sources such as abandoned mine water. However, these sources often contain hazardous heavy metals, like lead, copper, iron, and manganese, posing grave health and environmental risks. Conventional methods struggle to effectively treat these heavy metals in abandoned mining ponds, urging the search for cost‐efficient and sustainable solutions. Biochar, particularly from spent mushroom compost (SMC), emerges as a potent adsorbent due to its high surface area and binding groups. Yet, the variability in its efficiency remains a challenge. Conventional empirical models fail to capture the dynamic nature of adsorption processes accurately. Adopting machine learning, specifically an adaptive neuro‐fuzzy inference system (ANFIS), shows potential in predicting adsorption efficiency. This study aims to employ ANFIS to forecast SMC biochar's performance in a lab‐scale metal retention pond, providing design charts for diverse initial metal concentrations and pH levels. Validation through real cases aims to enhance accuracy and establish a framework for future heavy metal adsorption capacities. This research offers a sustainable approach to removing heavy metals from abandoned mining ponds whereas the computational modeling in optimizing SMC biochar introduces a novel approach for practical applications.
Algorithmic surveillance in the era of the mental health appsphere
Authors: Abdillahi Idil 
Published: March 2024

AbstractDigital mental health applications, also known as mHealth apps, are designed to help users manage their mental health using technology such as mobile devices and smartphones. However, there has been little critical engagement surrounding their impact on marginalized communities, and Black people in Canada. This article aims to explore how state and private actors conceptualize the digitalization of mental health access, leading to the creation and implementation of these apps. It is important to consider the links and interconnections between the platform and the app, and to be cautious and curious before adopting yet another app that claims to manage and mitigate moods and address mental health needs. We should be considering the implications of what comes with this access and apparent ease of use.

AbstractHaploidentical stem cell transplantation (haplo‐SCT) represents the main alternative for children with inherited bone marrow failure syndrome (I‐BMF) lacking a matched donor. This retrospective study, conducted on behalf of the EBMT SAAWP and PDWP, aims to report the current outcomes of haplo‐SCT in I‐BMFs, comparing the different in vivo and ex vivo T‐cell depletion approaches. One hundred and sixty‐two I‐BMF patients who underwent haplo‐SCT (median age 7.4 years) have been registered. Fanconi Anemia was the most represented diagnosis (70.1%). Based on different T‐cell depletion (TCD) approaches, four categories were identified: (1) TCRαβ+/CD19+‐depletion (43.8%); (2) T‐repleted with post‐transplant Cyclophosphamide (PTCy, 34.0%); (3) In‐vivo T‐depletion with ATG/alemtuzumab (14.8%); (4) CD34+ positive selection (7.4%). The cumulative incidences (CI) of neutrophil and platelet engraftment were 84% and 76% respectively, while that of primary and secondary graft failure was 10% and 8% respectively. The 100‐day CI of acute GvHD grade III‐IV(95% CI) was 13%, while the 24‐month CI of extensive chronic GvHD was 4%. After a median follow‐up of 43.4 months, the 2‐year overall survival(OS) and GvHD/Rejection‐free Survival (GRFS) probabilities are 67% and 53%, respectively. The TCR CD3+αβ+/CD19+ depletion group showed a significantly lower incidence of both acute and chronic GvHD and higher OS (79%; p0.013) and GRFS (71%; p < .001), while no significant differences in outcomes have been observed by different diagnosis and conditioning regimens. This large retrospective study supports the safety and feasibility of haplo‐SCT in I‐BMF patients. TCRαβ+/CD19+ depletion offers higher chances of patients' survival, with a significantly lower risk of severe a‐ and c‐GvHD in I‐BMFs compared to other platforms.

This work aimed to create and characterize some new bioactive chelates of bis azodye ligand, 5‐((2‐hydroxy‐4,6‐dioxo‐1,4,5,6‐tetrahydropyrimidin‐5‐yl)diazenyl)naphthalen‐1‐yl)diazenyl) pyrimidine 2,4,6 (1H,3H,5H)‐trione. Except for the Sm(III) chelate, which exhibited a (3M:1L) molar ratio, all chelates had a (2M:1L) stoichiometry. According to Fourier transform infrared spectroscopy (FT‐IR), azo groups were not included in chelating with all ions except Sm(III), where just one azo group was coordinated. With the Ni(II) and Zn(II) ions, the ligand behaved as OON‐tridentate moiety; with the Co(II) and Cu(II) ions, it behaved as ON‐bidentate moiety. Co(II) and Cu(II) chelates had square planar structure, and Ni(II) and Zn(II) chelates had square pyramidal geometry. The chelates had greater thermal stability than the uncoordinated ligand due to the chelate's structure. [Sm3(H4L)(OH)7(NO3)2.H2O].4.5EtOH exhibited the maximum thermal stability, which may be due to the large number of solvent molecules and the high number of chelate rings. With the exception of the Sm(III) chelate, all of the examined chelates were more cytotoxic against MCF‐7 and Hep‐G2 cells than their parent ligand. With the exception of the Zn(II) chelate, which demonstrated activity on Hep‐G2 rather than MCF‐7, the effects of each metal chelate on the two cells were nearly equivalent. All of the studied chelates, especially Zn(II) and Co(II), were potent as antioxidants more than the native ligand. To support experimental findings, density functional theory (DFT) studies were performed via the CAM‐B3LYP/LanL2DZ method, and the geometry of the ligand and its chelates had been validated.
