João Joined the 2016-17 Executive Committee of Linguistics Program at The Graduate Center

The Executive Committee has the authority for the operation of the program between the stated meetings of the program’s faculty.  It serves as a Committee on Committees to prepare slates of nominees for the program’s representatives to Graduate Council.  The Executive Committee may make recommendations to the appropriate committees of Graduate Council and to the Graduate Center administration.  The Executive Committee in coordination with the Faculty Membership Committee conducts a continuing review of the faculty of the University relevant to that program.  The Executive Committee works with the Executive Officers to forward the policy in Section 3.4E of the Graduate School governance document concerning employment of CUNY doctoral students in part-time faculty positions in CUNY colleges.  The Executive Committee recommends policies and procedures on dissertations.

João Joined ARC, Columbia’s Alumni Representative Committee

“ARC members are Columbia ambassadors across the United States and around the world. While they hail from different professional backgrounds and graduation years, all have a desire to share their Columbia experience with prospective students. ARC members help the Office of Undergraduate Admissions by interviewing applicants, representing Columbia at local college fairs and hosting regional programs for admitted students, so that as many students as possible have the opportunity to learn about the unique Columbia experience firsthand.”  – website

Representations of Gay Men in the Dialogue of Will & Grace: A Corpus Driven Analysis and Social Discussion

By analyzing frequencies and collocates of character-divided subcorpora, this quantitative study describes the corpus-linguistic representation of gay men in Will & Grace. Results derived from these linguistic representations were used to provide evidence for or against proposed sociological theories on the subject.

Will & Grace provides, not a single-dimensional, positive, and socially progressive depiction of gay men, but a multifaceted portrayal that includes, whether intentionally or not, linguistic inequalities that depict homosexuality as not fully accepted or even acceptable. By placing these corpus-linguistic findings in conversation with the sociological studies mentioned, it becomes clearer that Will & Grace was hindered by the writers’ social perceptions about the audience it successfully attracted, in spite of being called a gay sitcom.  (Download the Paper)

Integrated proteomic and transcriptomic analysis of the Aedes aegypti eggshell

Background: Mosquito eggshells show remarkable diversity in physical properties and structure consistent with adaptations to the wide variety of environments exploited by these insects. We applied proteomic, transcriptomic, and hybridization in situ techniques to identify gene products and pathways that participate in the assembly of the Aedes aegypti eggshell. Aedes aegypti population density is low during cold and dry seasons and increases immediately after rainfall. The survival of embryos through unfavorable periods is a key factor in the persistence of their populations. The work described here supports integrated vector control approaches that target eggshell formation and result in Ae. aegypti drought-intolerant phenotypes for public health initiatives directed to reduce mosquito-borne diseases.

Conclusions: A total of 130 proteins were identified from the combined mass spectrometric analyses of eggshell preparations. Classification of proteins according to their known and putative functions revealed the complexity of the eggshell structure. Three novel Ae. aegypti vitelline membrane proteins were discovered. Odorant-binding and cysteine-rich proteins that may be structural components of the eggshell were identified. Enzymes with peroxidase, laccase and phenoloxidase activities also were identified, and their likely involvements in cross-linking reactions that stabilize the eggshell structure are discussed.

Determinants of Adult Narrative Maturity in Brazilian Portuguese Speakers (B.A. Thesis)

Two experiments were carried out map the relationship between adult narrative maturity, age, educational background, and distance from gaze context. As proxies for narrative maturity, this study relied on Epistemic Qualification & Self Correction, Description of Character Emotion, Temporal & Causal Event Segmentation, and Basic Overt Stringing.

Correlations were found between narrative maturity and different adult demographic groups. The correlations found, however, were inconsistent with those previously determined by child development studies.

​Future analysis of variables such as primary narrative tense and the use of active/passive perspectives may provide methods to reconcile the inconsistencies found. (Download the Thesis)

Tense and Aspect: Portuguese and Other Romance Languages

Members of the Western Romance Languages share roughly the same verb paradigm descended from Vulgar Latin. They retain the existence of most of the verb tenses found in Latin and share many of the innovations created upon the historical changes through Continental, Italo-Western, and Western Romance. These similarities are clear when comparing the verb paradigms of existent tenses in the languages, but the mere existence of a tense does not prove its usage.

Through a small-scale corpus analysis, it was determined that syntactic and semantic usage of written verb tenses retained a remarkable level of similarity across Portuguese, French, and Spanish.  The spoken usages, however, were significantly different. (Download the paper).

Wakhi Borrowings Register and Written Language

In spite of the rapid pace of lexical borrowings and language change in Wakhi, a language spoken in Wakhan, near the borders of Tajikistan, China, Afghanistan, and Pakistan, native speakers indicate that an the language has not developed a native Indo-Iranian higher register. (Download the paper).
