    The recent call for a critical university studies from the American Studies Association speaks to a growing body of criticism about university corporatism, specifically its "colonialization" through, and production of, student-debt. The subject centralizes constraints upon academic freedom vocationally and discursively, yet little focus has been on the role of the academic as a participating member of such an institution. The tacit significance of the role of the intellectual within colonialization should be explicitly juxtaposed with the unique position of the academic within the university, and new questions of discursive resistance can be interrogated by reviewing the relationship of the academic and the university, the academic and academic publishing, and academic publishing and the university. Although the theoretical and legal dependencies of academic criticism are paradoxically defined by their academic "discipline," ​the historical turn in both the role of the university, as a globalizing industry of student-debt culture, and the turn to a critical university studies, lends the American academic to be situated as the resistant subject in an unprecedented crisis of discourse. A review of "academic publishing" on Americanized student-debt teases out and introduces an arising crisis

    Integrated behavioral health care within primary care has become a popular style of health care delivery within the United States. However, individuals with a behavioral health concern face several barriers in using these services. The purpose of this quantitative study was to identify key factors accounting for individuals\u27 utilization and intensity of behavioral health services. Andersen\u27s behavioral model of health care use and the integrated theory of health behavior change served as the theoretical framework. It was hypothesized that gender, age, race, ethnicity, family size, payer type, poverty level, and certain preexisting medical conditions (obesity, diabetes, hypertension, and tobacco use) would determine behavioral health care utilization and intensity. A secondary data analysis of 315 individuals who used behavioral health services within primary care was performed; the study setting was at the Center for Health, Education, Medicine, and Dentistry, located in Lakewood, New Jersey. Among the individual variables examined, only a preexisting condition of hypertension reached statistical significance, showing that those individuals were more likely to attend multiple sessions, Ï?2 (1) = 5.77, p = .02. Payer type was also found to be predictive of behavioral health care intensity. Medicare recipients were more likely to attend multiple behavioral health care sessions (74%) than were Medicaid recipients (59%) and those who were uninsured (25%). By providing insights about the barriers faced by individuals, study findings may help patient advocates and health care professionals to provide individuals with better health care. This study has implications for positive social change, as study findings may assist the United States health care system in its shift toward an integrated behavioral health care style of health care delivery

    ABSTRACT HIV-1 protease (PR), reverse transcriptase (RT), and integrase (IN) variability presents a challenge to laboratories performing genotypic resistance testing. This challenge will grow with increased sequencing of samples enriched for proviral DNA such as dried blood spots and increased use of next-generation sequencing (NGS) to detect low-abundance HIV-1 variants. We analyzed PR and RT sequences from >100,000 individuals and IN sequences from >10,000 individuals to characterize variation at each amino acid position, identify mutations indicating APOBEC-mediated G-to-A editing, and identify mutations resulting from selective drug pressure. Forty-seven percent of PR, 37% of RT, and 34% of IN positions had one or more amino acid variants with a prevalence of ≥1%. Seventy percent of PR, 60% of RT, and 60% of IN positions had one or more variants with a prevalence of ≥0.1%. Overall 201 PR, 636 RT, and 346 IN variants had a prevalence of ≥0.1%. The median intersubtype prevalence ratios were 2.9-, 2.1-, and 1.9-fold for these PR, RT, and IN variants, respectively. Only 5.0% of PR, 3.7% of RT, and 2.0% of IN variants had a median intersubtype prevalence ratio of ≥10-fold. Variants at lower prevalences were more likely to differ biochemically and to be part of an electrophoretic mixture compared to high-prevalence variants. There were 209 mutations indicative of APOBEC-mediated G-to-A editing and 326 mutations nonpolymorphic treatment selected. Identification of viruses with a high number of APOBEC-associated mutations will facilitate the quality control of dried blood spot sequencing. Identifying sequences with a high proportion of rare mutations will facilitate the quality control of NGS. IMPORTANCE Most antiretroviral drugs target three HIV-1 proteins: PR, RT, and IN. These proteins are highly variable: many different amino acids can be present at the same position in viruses from different individuals. Some of the amino acid variants cause drug resistance and occur mainly in individuals receiving antiretroviral drugs. Some variants result from a human cellular defense mechanism called APOBEC-mediated hypermutation. Many variants result from naturally occurring mutation. Some variants may represent technical artifacts. We studied PR and RT sequences from >100,000 individuals and IN sequences from >10,000 individuals to quantify variation at each amino acid position in these three HIV-1 proteins. We performed analyses to determine which amino acid variants resulted from antiretroviral drug selection pressure, APOBEC-mediated editing, and naturally occurring variation. Our results provide information essential to clinical, research, and public health laboratories performing genotypic resistance testing by sequencing HIV-1 PR, RT, and IN

    At age 17 two motor signs, mirror movements and dysdiadochokinesis, were found in more than half the subjects known to have had the respective signs at age 7. These rates were significantly higher than rates found within the group of subjects who were sign free at age 7

    Sites of Circadian Clock Neuron Plasticity Mediate Sensory Integration and Entrainment

    Networks of circadian timekeeping in the brain display marked daily changes in neuronal morphology. In Drosophila melanogaster, the striking daily structural remodeling of the dorsal medial termini of the small ventral lateral neurons has long been hypothesized to mediate endogenous circadian timekeeping. To test this model, we have specifically abrogated these sites of daily neuronal remodeling through the reprogramming of neural development and assessed the effects on circadian timekeeping and clock outputs. Remarkably, the loss of these sites has no measurable effects on endogenous circadian timekeeping or on any of the major output functions of the small ventral lateral neurons. Rather, their loss reduces sites of glutamatergic sensory neurotransmission that normally encodes naturalistic time cues from the environment. These results support an alternative model: structural plasticity in critical clock neurons is the basis for proper integration of light and temperature and gates sensory inputs into circadian clock neuron networks

    Adult Circadian Behavior in Drosophila Requires Developmental Expression of cycle, But Not period

    Circadian clocks have evolved as internal time keeping mechanisms that allow anticipation of daily environmental changes and organization of a daily program of physiological and behavioral rhythms. To better examine the mechanisms underlying circadian clocks in animals and to ask whether clock gene expression and function during development affected subsequent daily time keeping in the adult, we used the genetic tools available in Drosophila to conditionally manipulate the function of the CYCLE component of the positive regulator CLOCK/CYCLE (CLK/CYC) or its negative feedback inhibitor PERIOD (PER). Differential manipulation of clock function during development and in adulthood indicated that there is no developmental requirement for either a running clock mechanism or expression of per. However, conditional suppression of CLK/CYC activity either via per over-expression or cyc depletion during metamorphosis resulted in persistent arrhythmic behavior in the adult. Two distinct mechanisms were identified that may contribute to this developmental function of CLK/CYC and both involve the ventral lateral clock neurons (LNvs) that are crucial to circadian control of locomotor behavior: (1) selective depletion of cyc expression in the LNvs resulted in abnormal peptidergic small-LNv dorsal projections, and (2) PER expression rhythms in the adult LNvs appeared to be affected by developmental inhibition of CLK/CYC activity. Given the conservation of clock genes and circuits among animals, this study provides a rationale for investigating a possible similar developmental role of the homologous mammalian CLOCK/BMAL1 complex
