    Dana Mohler-Faria Mohler-Faria was inaugurated as the eleventh president of Bridgewater in October 2002 after almost thirty years of administrative experience in Massachusetts public higher education. A native of southeastern Massachusetts, Mohler-Faria served in the U.S. Air Force before pursuing an associate’s degree from Cape Cod Community College (1972), followed by a BA (1974) and MA (1975) in history from Boston University and an EdD from the University of Massachusetts Amherst (1984). From 1975-1984, he was director of financial aid and of the SACHEM (Southeastern Association for Cooperation of Higher Education) outreach program at Cape Cod Community College. From 1984-1987, he served as assistant dean of administrative services at Bristol Community College. He then moved to Mt. Wachusett Community College where he was executive dean of administrative services and student affairs, dean of administrative services, and assistant to the president for business and industry. In 1991 Mohler-Faria was selected as vice president for administration and finance at Bridgewater, where he worked closely with President Tinsley on projects such as the construction of the Moakley Technology Center, the restoration of commuter rail service to campus, and the capital development campaign. Throughout his tenure as president, Mohler-Faria led and participated in regional and statewide projects to further higher education in Massachusetts. In 2003, Mohler-Faria spearheaded the establishment of the CONNECT partnership, linking Bridgewater with Bristol Community College, Cape Cod Community College, Massosoit Community College, Massachusetts Maritime Academy, and the University of Massachusetts-Dartmouth. That same year he initiated exploratory discussions with the Massachusetts state colleges’ Council of Presidents to consider seeking university status for the state colleges. Seven years of continued efforts were rewarded in July 2010 when the House of Representatives overwhelmingly approved legislation granting university status to the Commonwealth’s state colleges. During his tenure, a variety of programs aimed at academic enrichment and social support for at-risk youth in southeastern Massachusetts and the Greater Boston area were started. These included The Bridge Partnership with New Bedford Public Schools; FAM for Change, which paired BSU mentors with Brockton High freshmen deemed to be at high risk of dropping out; and the Concurrent Enrollment program, which provided the necessary support for students with cognitive disabilities as they attended BSU. The Bridgewater campus experience was transformed during Mohler-Faria’s presidency. The first LEED-certified residence hall opened in September 2007; the first LEED-certified academic building, the state-of-the-art Science and Mathematics Center, opened in September 2011. Full-time enrollment increased by almost one third, to over 9,200 students by 2014. The number of full-time faculty increased by over 30%, to over 330. The percentage of students of color climbed from 6.2 to over 16% of the total student body. The number of graduate degrees awarded yearly almost doubled. As part of Bridgewater’s mission to serve the residents of southeastern Massachusetts, permanent Bridgewater satellite campuses were opened in Attleboro, New Bedford, and Cape Cod. Mohler-Faria’s agenda included creating more opportunities for students to broaden their horizons through study abroad trips and forging partnerships with more than two dozen international universities. Highlighting the importance of international engagement to Bridgewater’s central mission, strategic planning and core curriculum, Mohler-Faria opened the Center for International Engagement in spring 2010 to support the Canadian, African, Latin-American, Asian, and Middle Eastern Studies programs.https://vc.bridgew.edu/presidents/1009/thumbnail.jp

    Longitudinal analysis of serum neutralization of SARS-CoV-2 Omicron BA.2, BA.4, and BA.5 in patients receiving monoclonal antibodies

    The emergence of Omicron sublineages impacts the therapeutic efficacy of anti-severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) monoclonal antibodies (mAbs). Here, we evaluate neutralization and antibody-dependent cellular cytotoxicity (ADCC) activities of 6 therapeutic mAbs against Delta, BA.2, BA.4, and BA.5. The Omicron subvariants escape most antibodies but remain sensitive to bebtelovimab and cilgavimab. Consistent with their shared spike sequence, BA.4 and BA.5 display identical neutralization profiles. Sotrovimab is the most efficient at eliciting ADCC. We also analyze 121 sera from 40 immunocompromised individuals up to 6 months after infusion of Ronapreve (imdevimab + casirivimab) or Evusheld (cilgavimab + tixagevimab). Sera from Ronapreve-treated individuals do not neutralize Omicron subvariants. Evusheld-treated individuals neutralize BA.2 and BA.5, but titers are reduced. A longitudinal evaluation of sera from Evusheld-treated patients reveals a slow decay of mAb levels and neutralization, which is faster against BA.5. Our data shed light on antiviral activities of therapeutic mAbs and the duration of effectiveness of Evusheld pre-exposure prophylaxis

    Adrian Rondileau

    Dr. Adrian Rondileau (1912-2002) became president of Bridgewater State College in September 1962 after a long and successful career in college and university teaching and administration, both at home and abroad. He received his BA in philosophy from the City College of New York in 1932 and his MA (1933) and Ph.D. (1935) from Columbia University in psychology and economics, respectively. After teaching for eight years at Central Michigan University, Rondileau left for a position as an exchange consultant and lecturer with Brazil’s Ministry of Education under the auspices of the U.S. State Department. Upon his return to the United States, Rondileau served as dean of business administration at the Associated Colleges of Upper New York and as dean of liberal arts at Pace University. From 1954 to 1962 he served as President of Yankton College in Yankton, South Dakota. Rondileau’s legacy includes an extensive building program and the willingness to open campus governance to more input from both faculty and students. During his tenure, the student body increased from 1,000 to 9,000, and the campus expanded from 36 to 170 acres. Bridgewater State’s first international exchange program began under Rondileau, with the 1984 faculty/student exchange agreement with Shanxi University in China. In 1967 Rondileau established a Town-College Committee to help build stronger relationships between the town of Bridgewater and the college. The following year he implemented a Faculty Council whose members were charged with making recommendations to the president concerning academic policy, professional standards, college development and faculty-student relations. Rondileau promoted active dialogue between the student body and the administration through forums and community meetings in order to avert student protests and anti-war demonstrations during the late 1960s and early 1970s. Campus expansion during Rondileau’s presidency included: The new Science Building – opened in September 1964 – named two years later in honor of Marshall Conant. The Great Hill residence halls - two new 300-bed student residences – opened in 1967 (later renamed in honor of George H. Durgin and Ellen M. Shea) The Student Union Building - opened in 1970 – named in honor of Rondileau in 1986 The new College Library – opened in May 1971 – named in honor of Clement C. Maxwell The new Student Apartments – opened in 1978 The Martha Burnell Campus School and Academic Complex – opened in the fall of 1979 Rondileau’s administration was guided by two basic principles. The first was the value of a broad-based education. The second was that after graduation, students should be prepared to become productive citizens after graduation. Rondileau announced his retirement in January 1986, effective the following September. As he left office, he was the third longest serving chief executive after the Boydens. In 1988, two years after his retirement, he returned to campus as acting president for the 1988-1989 academic year, following the scandalous tenure of Bridgewater’s 9th president, Gerard Indelicato. Rondileau died on November 20, 2002, at the age of 90.https://vc.bridgew.edu/presidents/1007/thumbnail.jp

    Boundary Algebra: A Simpler Approach to Boolean Algebra and the Sentential Connectives

    No full text
    Boundary algebra [BA] is a algebra of type , and a simplified notation for Spencer-Brown’s (1969) primary algebra. The syntax of the primary arithmetic [PA] consists of two atoms, () and the blank page, concatenation, and enclosure between ‘(‘ and ‘)’, denoting the primitive notion of distinction. Inserting letters denoting, indifferently, the presence or absence of () into a PA formula yields a BA formula. The BA axioms are A1: ()()= (), and A2: “(()) [abbreviated ‘⊥’] may be written or erased at will,” implying (⊥)=(). The repeated application of A1 and A2 simplifies any PA formula to either () or ⊥. The basis for BA is B1: abc=bca (concatenation commutes & associates); B2, ⊥a=a (BA has a lower bound, ⊥); B3, (a)a=() (BA is a complemented lattice); and B4, (ba)a=(b)a (implies that BA is a distributive lattice). BA has two intended models: (1) the Boolean algebra 2 with base set B={(),⊥}, such that () ⇔ 1 [dually 0], (a) ⇔ a′, and ab ⇔ a∪b [a∩b]; and (2) sentential logic, such that () ⇔ true [false], (a) ⇔ ~a, and ab ⇔ a∨b [a∧b]. BA is a self-dual notation, facilitates a calculational style of proof, and simplifies clausal reasoning and Quine’s truth value analysis. BA resembles C.S. Peirce’s graphical logic, the symbolic logics of Leibniz and W.E. Johnson, the 2 notation of Byrne (1946), and the Boolean term schemata of Quine (1982).Boundary algebra; boundary logic; primary algebra; primary arithmetic; Boolean algebra; calculation proof; G.

    Monitoring of the SARS-CoV-2 Omicron BA.1/BA.2 lineage transition in the Swedish population reveals increased viral RNA levels in BA.2 cases

    No full text
    BACKGROUND: Throughout the SARS-CoV-2 pandemic, multiple waves of variants of concern have swept across populations, leading to a chain of new and yet more contagious variants dominating COVID-19 cases. Here, we tracked the remarkably rapid shift from Omicron BA.1 to BA.2 sublineage dominance in the Swedish population in early 2022 at a day-by-day basis. METHODS: Using a custom SARS-CoV-2 Omicron BA.1 lineage-typing RT-PCR assay, we analyzed 174,933 clinical upper airway samples collected during January to March 2022. FINDINGS: Our study demonstrates the feasibility and reliability of parallel lineage assignment of select variants at population scale, tracking the dominant sublineage transition from BA.1 to BA.2 at day-to-day resolution and uncovering nearly 2-fold higher levels of viral RNA in cases infected with Omicron BA.2 relative to BA.1. CONCLUSIONS: Our data provide unique insights into the Omicron BA.1 to BA.2 transition that occurred in Sweden during early 2022, and later, across the world. This may help to understand the increased transmissibility of the BA.2 variant

    [[alternative]]A Pedagogical Grammar of the Chinese Disposal(Ba) Construction

    No full text
    [[abstract]]Current pedagogical grammar of the Chinese disposal construction (ba) is based on Shou-hsin Teng’s theoretical framework and methodology in his A Pedagogical Grammar of Chinese (2003), which draws on 7,710 examples from a corpus of authentic material and theoretical linguistics/grammar research, and emphasizes the learner as a crucial parameter, providing an exhaustive description of the Chinese disposal construction. In my thesis, I identify three semantic functions of the Chinese disposal construction based on Teng’s theoretical framework: disposal, accidental, and causative. (The disposal semantic function comprises 94.53% of the 7,288 examples in the Academia Sinica Corpus.) Additionally, I seek to establish seven basic sub-structures of the disposal construction: ba 1) S ba OV + aspect; ba 2) S ba OV + result; ba 3) S ba OV + goal; ba 4) S ba OV + direction; ba 5) S ba OV + extent; ba 6) S ba OV + range; ba 7) S ba OV + reduplication. Drawing on Teng’s principles regarding multiple sequences and the assessment of the difficulty grammar of points, I posit eight principles for assessing the difficulty of seven disposal construction sub-structures, and order such sub-structures according to their level of difficulty; in so doing, I assess the sequencing, pedagogical stages, and grading of the sub-structures, and create a model for disposal construction pedagogy which includes a series of computer-based, task-oriented scenarios. I believe my thesis can help bridge the gap between the fields of pedagogical grammar and pedagogy, and provide a discursive platform on which relevant issues can be further examined. Hopefully, my research and the potential discursive platform arising from it will lend themselves to discrediting the common belief that disposal construction pedagogy is best formulated according to an educator’s personal experiences. This thesis thereby situates the pedagogy of the disposal construction firmly in the realm of empirical science. Additionally, I seek to help educators to develop their pedagogical methodology according to my sequence of the disposal construction, and to systematically improve their teaching methods. In so doing, educators will enable second language learners not only to fully grasp the disposal construction and other related grammar points, but also to grasp the entirety of the Chinese grammar system. Thus they will ultimately allow learners to actively engage speakers of the target language in an appropriate, effective manner.
