Dual Enrollment Policies and Practices

The James Irvine Foundation joins educators and policymakers across the country who share a growing interest in the potential of dual enrollment. In particular, when high school students take college courses to earn transferable college credits, how are they positioned to succeed in college and career? How can we expand this opportunity to a broader range of students? Irvine's Youth program seeks to help increase the number of low-income youth in California who complete high school on time and attain a postsecondary credential by age 25. To ensure access to better educational and economic opportunities for a diverse group of students, our funding supports multiple pathways to the same destination: success in high school, college and careers. The multiple pathways approach integrates rigorous academics with demanding career and technical education, comprehensive student support services and relevant work-based learning opportunities, so that all high school students are prepared for both college and career. Research suggests that career-focused dual enrollment programs can improve secondary and postsecondary academic outcomes for a variety of students. In this context, the Concurrent Courses initiative was created to demonstrate the feasibility of using dual enrollment to enhance career and technical education pathways -- particularly for low-income youth who are struggling academically or who are within populations historically underrepresented in higher education. The Concurrent Courses initiative is being managed by the Community College Research Center (CCRC) housed at Teachers College, Columbia University. We would like to thank and recognize the authors of this brief: Joanne Wang Golann, who is a Senior Research Assistant and Katherine L. Hughes, who is the Assistant Director for Work and Education Reform Research at CCRC. The authors conducted extensive research on the dual enrollment environment in California in preparation for Concurrent Courses. This brief shares their analysis with the field to clarify the opportunities and challenges for supporting promising pathways to college

Different Approaches to Dual Enrollment: Understanding Program Features and Their Implications

Abdominal Ectopic Pregnancy and Impaired Postnatal Mammary Gland Development, Consistent With Physiologic Agalactia, in a Wild European Rabbit, Oryctolagus cuniculus.

A wild European rabbit, Oryctolagus cuniculus, was diagnosed with an abdominal pregnancy due to the presence of a single abdominal lithopedion attached by a thin fibrovascular stalk to the left uterine horn, which was distorted by the tension of the adhesion. Evidence of mineralized remnants, chronic inflammation, and fibrosis in the left uterine endometrium and myometrium suggested that the lithopedion had arisen as a secondary abdominal pregnancy. The right uterine horn contained two macroscopically normal fetuses. The mammary gland exhibited notably retarded development in relation to the size of the fetuses. Histologically, mammary alveoli lacked evidence of intraluminal secretory product, and ducts lacked prominence and contained clusters of small numbers of macrophages. The doe also exhibited mild granulomatous and heterophilic pneumonia with rare intralesional adiaspores, suggesting infection with Emmonsia spp. as an incidental finding. This case documents secondary abdominal pregnancy in a wild lagomorph not subjected to artificial insemination procedures suggested to increase the occurrence of this condition in farmed rabbits. An abdominal pregnancy is one of a number of factors that should be considered as a potential factor in the etiology of impaired postnatal mammary development or reduced milk yield in a breeding doe, although no causative association is demonstrated in this case. Abdominal ectopic pregnancy is one possible differential diagnosis in the investigation of the presence of a palpable abdominal mass or masses in O. cuniculus.Girton Colleg

Comparative mammary gland postnatal development and tumourigenesis in the sheep, cow, cat and rabbit: Exploring the menagerie.

Sheep, cows, cats, and rabbits are kept by humans for agricultural purposes and as companion animals. Much of the mammary research in these species has focussed on mastitis in the case of ruminants and rabbits, and mammary tumourigenesis in cats and rabbits. However, similarities with the human breast suggest that these species may be currently underutilised as valuable comparative models of breast development and disease. The mammary gland undergoes cyclical postnatal development that will be considered here in the context of these non-traditional model species, with a focus on the mammary microenvironment at different postnatal developmental stages. The second part of this review will consider mammary tumour development. Ruminants are thought to be relatively 'resistant' to mammary tumourigenesis, likely due to multiple factors including functional properties of ruminant mammary stem/progenitor cells, diet, and/or the fact that production animals undergo a first parity soon after puberty. By contrast, unneutered female cats and rabbits have a propensity to develop mammary neoplasms, and subsets of these may constitute valuable comparative models of breast cancer.Pathological Society of Great Britain and Ireland [grant number ICA 1019 02]; and the British Veterinary Association Animal Welfare Foundation Norman Hayward Fund [grant number NHF_2016_03_KH]

Broadening the Benefits of Dual Enrollment: Reaching Underachieving and Underrepresented Students with Career-Focused Programs

A three-year study tracking outcomes for thousands of students across California shows that careerfocused dual enrollment programs can provide important benefits for those who are underachieving and underrepresented in higher education. Programs of this type, which allow high school students to take college courses and earn college credit, were once offered almost exclusively to high-achieving students seeking greater academic challenge

Mating system and population genetic structure of the bulldog ant Myrmecia pavida

Understanding the evolution of the alternative mating strategies of monandry and polyandry is a fundamental problem in evolutionary biology because of the cost-benefit trade-offs associated with mating for females. The problem is particularly intriguing in the social insects because queens in most species appear to be obligately monandrous (i.e., only a single male fathers their offspring), while those in a minority of species have evolved high, and sometimes extreme, polyandry. One group which may shed particular insight is the ant subfamily Myrmeciinae (Myrmecia and Nothomyrmecia). Here we examine the population and colony genetic structure of the bulldog ant Myrmecia pavida CLARK, 1951 by genotyping offspring workers from 45 colonies. We find little evidence of geographic structuring or inbreeding in the population, indicating that the species outbreeds, most probably in mating swarms. We also find that queens of M pavida show moderately high polyandry, with 84% having mated with between two and seven males, and an overall mean observed mating frequency of 3.8. This is significantly higher than previously reported for queens of Nothomyrmecia macrops, in which most females mate singly. This was similar to that of M pyriformis, M brevinoda, and M pilosula, the three congenerics for which mating frequencies have recently been reported. The two genera in the Myrmeciinae therefore appear to show multiple transitions in mating frequency and further investigation of the subfamily may be highly informative for disentangling the forces driving the evolution of alternative mating strategies

Diagnosis of equine penile and preputial masses: A clinical and pathological perspective

Masses of the prepuce and penis are common clinical presentations for the equine veterinarian, encompassing a number of differential diagnoses. In such cases, it is important to evaluate the external genitalia thoroughly and devise a methodical diagnostic and treatment plan to allow for accurate prognostication and optimal survival rates. Masses of the prepuce and penis include tumours of epithelial, mesenchymal or round cell origin, such as squamous cell carcinoma (SCC), papillomas, melanocytic tumours, lymphoma, sarcoids, fibrosarcomas (Van Den Top et al. 2010) and fibromas; the latter as described by De Meyer et al. in this issue (De Meyer et al. 2015). Non-neoplastic conditions that can result in masses or enlargement of the external genitalia in male horses include infection or inflammation (primary, or secondary to neoplasia) leading to balanitis or balanoposthitis. Such diseases frequently lead to chronic irritation and discomfort. Some neoplastic conditions may metastasise to cause more severe sequelae.This is the author accepted manuscript.
