Measuring the Promise: A Learning Focused Syllabus Rubric

To enrich the resources for measuring the impact of educational development work, we have created a rubric to assess the degree to which a syllabus achieves a learning orientation. The rubric provides qualitative descriptions of components that distinguish learning focused syllabi and uses a quantitative scoring system that places syllabi on a spectrum from content focused to learning focused. It is flexible enough to accommodate a diverse range of levels, disciplines, institutions, and learning environments, yet nuanced enough to provide summative information to developers using the tool for assessment purposes and formative feedback to instructors interested in gauging the focus of their syllabi

Systematic Assessment of a High Impact Course Design Institute

Herein, we describe an intensive, week long course design institute (CDI) designed to introduce participants to the scholarly and evidence driven process of learning focused course design. Impact of this intervention is demonstrated using a multifaceted approach: (a) post CDI satisfaction and perception surveys, (b) pre /post CDI surveys probing pedagogical confidence and perceptions regarding importance of syllabi components, and (c) pre /post CDI syllabi analysis using a reliable syllabus rubric validated for higher education courses. The combined results of these qualitative and quantitative studies indicate that participants value the CDI experience, believe they learn basic principles of learning focused course design, report they are more confident enacting learning focused concepts in the classroom, believe they are better able to design learning focused syllabi, and they actually design more learning focused courses/syllabi

Peel, Pare, Plate, Post: Repository Mise en Place for Collecting Faculty Articles

Mise en place (pronounced “meez ahn plahs”) is a term used in professional kitchens to describe the organizing and arranging of the workspace, ingredients, and equipment before beginning to cook. It translates directly from French as “to put in place” (“Mise en Place,” n.d.). A carefully constructed mise en place is the key to this recipe for adding faculty articles to an institutional repository (IR). Step by step, this recipe details one proven way for a head chef to prepare a scholarly communication kitchen for this project: (1) identifying sous-chefs to assist in the project, (2) gathering ingredients from multiple sources, (3) peeling and chopping the ingredients into morsels of essential information, (4) collecting and arranging these morsels so they are all within easy reach, and (5) combining them into small, easily digestible outreach emails to faculty

Project Safe Flight: Making New York Safe for Migratory Birds

More than 100 species of migratory birds pass through New York City during spring and fall migrations. Located at the nexus of several migratory routes, New York City’s tall buildings and reflective glass pose a serious threat to over 100 species of migratory birds. Since 1997, NYC Audubon has led Project Safe Flight (PSF), a volunteer-based citizen-science project, with the goal of monitoring and mitigating bird collisions. We examined 16 years of PSF data, during which volunteers collected over 6,000 birds of 126 different species. The top two species, White-throated Sparrow and Common Yellowthroat, make up 23% of all collisions. The fall migration has a higher average number of collisions than spring. Distinct phenological trends in species composition are apparent, with American Woodcock making up the majority of early spring collisions and Dark-eyed Junco being the most common in late fall. Because birds may be overlooked by volunteers or be taken by scavengers or maintenance crews after collisions, we performed a persistence study and found that the recovery of bird carcasses was highly variable between sites. This ongoing study is important in developing a database of bird collisions to help elucidate and reduce the causes of urban bird collisions

Amplifying CUNY Voices with CUNY Academic Works

While most conversations about open access literature center on journal articles and books, research takes many other forms. CUNY Academic Works provides a platform for, and public access to, a wide range of CUNY-created scholarship. In this presentation, we discuss the importance of including Women\u27s Studies Newsletter (the predecessor of Women\u27s Studies Quarterly), Latino Data Project Reports, and theses and dissertations in Academic Works, and report on a recent census of journals published by the CUNY community

Experimental field tests of Batesian mimicry in the swallowtail butterfly <i>Papilio polytes</i>

The swallowtail butterfly Papilio polytes is known for its striking resemblance in wing pattern to the toxic butterfly Pachliopta aristolochiae and is a focal system for the study of mimicry evolution. Papilio polytes females are polymorphic in wing pattern, with mimetic and nonmimetic forms, while males are monomorphic and nonmimetic. Past work invokes selection for mimicry as the driving force behind wing pattern evolution in P. polytes. However, the mimetic relationship between P. polytes and P. aristolochiae is not well understood. In order to test the mimicry hypothesis, we constructed paper replicas of mimetic and nonmimetic P. polytes and P. aristolochiae, placed them in their natural habitat, and measured bird predation on replicas. In initial trials with stationary replicas and plasticine bodies, overall predation was low and we found no differences in predation between replica types. In later trials with replicas mounted on springs and with live mealworms standing in for the butterfly's body, we found less predation on mimetic P. polytes replicas compared to nonmimetic P. polytes replicas, consistent with the predator avoidance benefits of mimicry. While our results are mixed, they generally lend support to the mimicry hypothesis as well as the idea that behavioral differences between the sexes contributed to the evolution of sexually dimorphic mimicry

Ceramide levels regulated by carnitine palmitoyl transferase 1C control dendritic spine maturation and cognition

The brain-specific isoform carnitine palmitoyltransferase 1C (CPT1C) has been implicated in the hypothalamic regulation of food intake and energy homeostasis. Nevertheless, its molecular function is not completely understood, and its role in other brain areas is unknown. We demonstrate that CPT1C is expressed in pyramidal neurons of the hippocampus and is located in the endoplasmic reticulum throughout the neuron, even inside dendritic spines. We used molecular, cellular, and behavioral approaches to determine CPT1C function. First, we analyzed the implication of CPT1C in ceramide metabolism. CPT1C overexpression in primary hippocampal cultured neurons increased ceramide levels, whereas in CPT1C-deficient neurons, ceramide levels were diminished. Correspondingly, CPT1C knock-out (KO) mice showed reduced ceramide levels in the hippocampus. At the cellular level, CPT1C deficiency altered dendritic spine morphology by increasing immature filopodia and reducing mature mushroom and stubby spines. Total protrusion density and spine head area in mature spines were unaffected. Treatment of cultured neurons with exogenous ceramide reverted the KO phenotype, as did ectopic overexpression of CPT1C, indicating that CPT1C regulation of spine maturation is mediated by ceramide. To study the repercussions of the KO phenotype on cognition, we performed the hippocampus-dependent Morris water maze test on mice. Results show that CPT1C deficiency strongly impairs spatial learning. All of these results demonstrate that CPT1C regulates the levels of ceramide in the endoplasmic reticulum of hippocampal neurons, and this is a relevant mechanism for the correct maturation of dendritic spines and for proper spatial learning

Differential frequency of NKG2C/KLRC2 deletion in distinct African populations and susceptibility to Trachoma: a new method for imputation of KLRC2 genotypes from SNP genotyping data.

NKG2C is an activating receptor that is preferentially expressed on natural killer (NK) cells. The gene encoding NKG2C (killer cell lectin-like receptor C2, KLRC2) is present at different copy numbers in the genomes of different individuals. Deletion at the NKG2C locus was investigated in a case-control study of 1522 individuals indigenous to East- and West-Africa and the association with the ocular Chlamydia trachomatis infection and its sequelae was explored. The frequency of homozygous KLRC2 deletion was 13.7 % in Gambians and 4.7 % in Tanzanians. A significantly higher frequency of the deletion allele was found in West-Africans from the Gambia and Guinea-Bissau (36.2 % p = 2.105 × 10(-8), 26.8 % p = 0.050; respectively) in comparison to East-African Tanzanians where the frequency of the deletion is comparable to other human populations (20.9 %). We found no evidence for an association between the numbers of KLRC2 gene copies and the clinical manifestations of trachoma (follicular trachoma or conjunctival scarring). A new method for imputation of KLRC2 genotypes from single nucleotide polymorphism (SNP) data in 2621 individuals from the Gambia further confirmed these results. Our data suggest that NKG2C does not play a major role in trachomatous disease. We found that the deletion allele is present at different frequencies in different populations but the reason behind these differences is currently not understood. The new method offers the potential to use SNP arrays from genome wide association studies to study the frequency of KLRC2 deletion in other populations and its association with other diseases

Novel prokaryotic expression of thioredoxin-fused insulinoma associated protein tyrosine phosphatase 2 (IA-2), its characterization and immunodiagnostic application

Background The insulinoma associated protein tyrosine phosphatase 2 (IA-2) is one of the immunodominant autoantigens involved in the autoimmune attack to the beta-cell in Type 1 Diabetes Mellitus. In this work we have developed a complete and original process for the production and recovery of the properly folded intracellular domain of IA-2 fused to thioredoxin (TrxIA-2ic) in Escherichia coli GI698 and GI724 strains. We have also carried out the biochemical and immunochemical characterization of TrxIA-2icand design variants of non-radiometric immunoassays for the efficient detection of IA-2 autoantibodies (IA-2A). Results The main findings can be summarized in the following statements: i) TrxIA-2ic expression after 3 h of induction on GI724 strain yielded ≈ 10 mg of highly pure TrxIA-2ic/L of culture medium by a single step purification by affinity chromatography, ii) the molecular weight of TrxIA-2ic (55,358 Da) could be estimated by SDS-PAGE, size exclusion chromatography and mass spectrometry, iii) TrxIA-2ic was properly identified by western blot and mass spectrometric analysis of proteolytic digestions (63.25 % total coverage), iv) excellent immunochemical behavior of properly folded full TrxIA-2ic was legitimized by inhibition or displacement of [35S]IA-2 binding from IA-2A present in Argentinian Type 1 Diabetic patients, v) great stability over time was found under proper storage conditions and vi) low cost and environmentally harmless ELISA methods for IA-2A assessment were developed, with colorimetric or chemiluminescent detection. Conclusions E. coli GI724 strain emerged as a handy source of recombinant IA-2ic, achieving high levels of expression as a thioredoxin fusion protein, adequately validated and applicable to the development of innovative and cost-effective immunoassays for IA-2A detection in most laboratories.Fil: Guerra, Luciano Lucas.

Outbreak of Cyclosporiasis Associated with Imported Raspberries, Philadelphia, Pennsylvania, 2000

An outbreak of cyclosporiasis occurred in attendees of a wedding reception held in Philadelphia, Pennsylvania, on June 10, 2000. In a retrospective cohort study, 54 (68.4%) of the 79 interviewed guests and members of the wedding party met the case definition. The wedding cake, which had a cream filling that included raspberries, was the food item most strongly associated with illness (multivariate relative risk, 5.9; 95% confidence interval, 3.6 to 10.5). Leftover cake was positive for Cyclospora DNA by polymerase chain reaction analyses. Sequencing of the amplified fragments confirmed that the organism was Cyclospora cayetanensis. The year 2000 was the fifth year since 1995 that outbreaks of cyclosporiasis definitely or probably associated with Guatemalan raspberries have occurred in the spring in North America. Additionally, this is the second documented U.S. outbreak, and the first associated with raspberries, for which Cyclospora has been detected in the epidemiologically implicated food item
