African-American Enrollment and Retention in Higher Education: An Application of Game Theory
This study is a qualitative analysis of perceptions of institutional commitment to the enrollment and retention of African-American students at one institution. The study, which was funded by the Spencer Foundation, was conducted at Oberlin College and is based on 31 interviews of students, faculty, administrators, and staff. At many predominantly white campuses, low enrollment and poor retention of African-American students is a present and escalating problem. However, Oberlin College has unusually high enrollment and retention rates for African-American students. We wanted to explore the possible reasons for this uniqueness. We relate our findings to the process of constructing theories that explain some of the characteristics of Oberlin\u27s organizational culture
Pilot, randomized, placebo-controlled clinical field study to evaluate the effectiveness of bupivacaine liposome injectable suspension for the provision of post-surgical analgesia in dogs undergoing stifle surgery
Abstract Background Local anesthetics are an important component of perioperative pain management, but the duration of action of available products is limited. We hypothesized that a single local infiltration of a novel bupivacaine liposome injectable suspension (AT-003) would provide clinically effective analgesia over a 72-h period. In a masked, randomized, placebo-controlled, multi-center pilot field study, dogs undergoing lateral retinacular suture placement for cranial cruciate insufficiency were randomly assigned to surgical site infiltration with AT-003 (5.3 mg/kg) or an equivalent volume of saline. Infiltration of the surgical site was done prior to closure. Primary outcome measure was the Glasgow Composite Measure Pain Scale (CMPS-SF) assessed prior to surgery and at 2, 4, 8, 12, 24, 30, 36, 48, 54, 60 and 72 h following surgery by trained individuals. Provision for rescue analgesia was employed. Repeated measures analysis of variance were utilized to test for possible differences between treatment groups and a success/failure analysis was also employed, based on the need for rescue analgesia. Results Forty-six dogs were enrolled and evaluated. For CMPS-SF scores there was a significant overall treatment effect (p = 0.0027) in favor of AT-003. There were significantly more successes in the AT-003 group compared to placebo over each time period (p = 0.0001 for 0–24 h, p = 0.0349 for 0–48 h, and p = 0.0240 for 0-72 h). No significant adverse events were seen. Conclusions AT-003 (bupivacaine liposome injectable suspension) provided measurable local analgesia over a 72-h period following post-stifle surgery surgical site tissue infiltration. Further work is indicated to develop this product for clinical use
Emotional, informational, and decision-making support needs among people seeking abortion in the US: perspectives from All-Options Talkline callers
People seeking abortion may need or want emotional or informational support before, during, and after their abortion. Feeling supported and affirmed contributes to perceptions of quality care. The All-Options Talkline offers free, telephone-based, peer counselling to callers anywhere in the United States. This study aimed to explore the types of support received through the Talkline and the ways it supplemented other forms of support received by people who obtained an abortion. Between May 2021 and February 2022, we conducted 30 interviews via telephone or Zoom with callers recruited through the Talkline. We coded the interviews and conducted thematic analysis, focusing on themes related to gaps of support from family, friends, and healthcare professionals, as well as types of support received through the Talkline. We identified four key motivations for calling the Talkline, including the need for (1) decision-making support and validation, (2) a neutral perspective, (3) emotional support to discuss negative or complex feelings, and (4) information about the abortion process. Participants indicated that interactions with family, friends, and healthcare professionals ranged from unsupportive and negative, to substantially supportive. Access to the Talkline was particularly useful prior to clinical interactions and in the weeks or months after an abortion. We found that the All-Options Talkline provided person-centred, remote support for callers, filling gaps or supplementing support from one's community or healthcare professionals. Abortion support from non-medically trained support people contributes to high-quality abortion care, especially in a time of increasing abortion restrictions and use of remote abortion services
Identification of the V(H) genes encoding xenoantibodies in non-immunosuppressed rhesus monkeys
The major immunological barrier that prevents the use of wild-type pig xenografts as an alternative source of organs for human xenotransplantation is antibody-mediated rejection. In this study, we identify the immunoglobulin variable region heavy (IgV(H)) chain genes encoding xenoantibodies to porcine heart and fetal porcine islet xenografts in non-immunosuppressed rhesus monkeys. We sought to compare the IgV(H) genes encoding xenoantibodies to porcine islets and solid organ xenografts. The immunoglobulin M (IgM) and IgG xenoantibody response was analysed by enzyme-linked immunosorbent assay and cDNA libraries from peripheral blood lymphocytes were prepared and sequenced. The relative frequency of IgV(H) gene usage was established by colony filter hybridization. Induced xenoantibodies were encoded by the IGHV3-11 germline progenitor, the same germline gene that encodes xenoantibodies in humans mounting active xenoantibody responses. The immune response to pig xenografts presented as solid organs or isolated cells is mediated by identical IgV(H) genes in rhesus monkeys. These animals represent a clinically relevant model to identify the immunological basis of pig-to-human xenograft rejection
