    Trajectories of university adjustment in the United Kingdom: Emotion management and emotional self-efficacy protect against initial poor adjustment

    Little is known about individual differences in the pattern of university adjustment. This study explored longitudinal associations between emotional self-efficacy, emotion management, university adjustment, and academic achievement in a sample of first year undergraduates in the United Kingdom (N=331). Students completed measures of adjustment to university at three points during their first year at university. Latent Growth Mixture Modeling identified four trajectories of adjustment: (1) low, stable adjustment, (2) medium, stable adjustment, (3) high, stable adjustment, and (4) low, increasing adjustment. Membership of the low, stable adjustment group was predicted by low emotional self-efficacy and low emotion management scores, measured at entry into university. This group also had increased odds of poor academic achievement, even when grade at entry to university was controlled. Students who increased in adjustment had high levels of emotion management and emotional self-efficacy, which helped adaptation. These findings have implications for intervention

    An approach for wellbore failure analysis using rock cavings and image processing

    There have been interests to link different cuttings/cavings to various wellbore failure types during drilling. This concept is essential when caliper and image logs are not available. Identification of wellbore failure during drilling gives more chance of immediate actions before wireline logging program. In this paper, an approach was presented based on the image processing of ditch cuttings. This approach uses the sphericity and roundness of cuttings as input data to classify caving types and subsequently determine the dominant failure type. Likewise, common definitions of cavings were discussed initially before a new criterion is suggested. This quantitative criterion was examined by observations from caliper and acoustic image logs as well. The proposed approach and criterion were implemented on ditch cuttings taken from a well in Western Australia. Results indicate that the primary failure is shear failure (breakout) due to high levels of angular cavings. However, another failure due to the fluid invasion into pre-existing fractures was also recorded by blocky cavings

    Solar Fusion Cross Sections

    We review and analyze the available information for nuclear fusion cross sections that are most important for solar energy generation and solar neutrino production. We provide best values for the low-energy cross-section factors and, wherever possible, estimates of the uncertainties. We also describe the most important experiments and calculations that are required in order to improve our knowledge of solar fusion rates.Comment: LaTeX file, 48 pages (figures not included).

    Predictors of severe relapse in pregnant women with psychotic or bipolar disorders

    Pregnancy in women with severe mental illness is associated with adverse outcomes for mother and infant. There are limited data on prevalence and predictors of relapse in pregnancy. A historical cohort study using anonymised comprehensive electronic health records from secondary mental health care linked with national maternity data was carried out. Women with a history of serious mental illness who were pregnant (2007–2011), and in remission at the start of pregnancy, were studied; severe relapse was defined as admission to acute care or self-harm. Predictors of relapse were analysed using random effects logistic regression to account for repeated measures in women with more than one pregnancy in the study period. In 454 pregnancies (389 women) there were 58 (24%) relapses in women with non-affective psychoses and 25 (12%) in women with affective psychotic or bipolar disorders. Independent predictors of relapse included non-affective psychosis (adjusted OR = 2.03; 95% CI = 1.16–3.54), number of recent admissions (1.37; 1.03–1.84), recent self-harm (2.24; 1.15–4.34), substance use (2.15; 1.13–4.08), smoking (2.52; 1.26–5.02) and non-white ethnicity (black ethnicity: 2.37; 1.23,4.57, mixed/other ethnicity: 2.94; 1.32,6.56). Women on no regular medication throughout first trimester were also at greater risk of relapse in pregnancy (1.99; 1.05–3.75). There was no interaction between severity of illness and medication status as relapse predictors. Therefore, women with non-affective psychosis and higher number of recent acute admissions are at significant risk of severe relapse in pregnancy. Continuation of medication in women with severe mental illness who become pregnant may be protective

    Epidemiology of endometrial neoplasia

    Though among U.S. women endometrial cancer is the most common invasive gynecological cancer, it has a relatively favorable prognosis. From 1986–1990, approximately 19% of U.S. Surveillance, Epidemiology and End Results (SEER) Program cases were diagnosed in women less than 55 years of age; however, the age-specific incidence (per 100,000) peaked at 70–74 years (110.7), which was 2.85 times the rate reported at 50–54 years (38.9). The incidence under 50 years was 2.19 times higher in U.S. White compared with U.S. Black women; for uterine corpus cancers diagnosed at 50 years and older, the ratio declined but continued to be elevated in Whites (1.46). In contrast, average annual age-adjusted mortality (per 100,000) from 1986–1990 for uterine corpus cancer (1970 U.S. standard) was almost twice as high in U.S. Black women (6.0) as in U.S. White women (3.3). The determinants of age-specific elevated risks in moratlity, in contrast to the lesser age-specific risks in incidence experienced by U.S. Black women compared with U.S. White women, may be explored with respect to socioeconomics and cultural factors that influence the distribution of epidemiologic risk factors such as reproductive history, choice of contraception methods, hormone replacement therapy, and dietary factors; age-specific prevalence of hysterectomy for other gynecological conditions; quality of medical care and surveillance practices; genetic factors infleuncing susceptibility; and tumor-associated biological factors. The majority of risk factors and medical conditions associated with endometrial cancer are related directly or indirectly to the levels and metabolic effects of the reproductive hormones, namely estrogens and progestogens. The molecular, genetic, and epidemiologic characterization of endometrial cancer is attempting to delineate the multiple steps in the natural history of estrogen-induced or estrogen-responsive neoplasms.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/38460/1/240590920_ftp.pd

    Putting Youth on the Map: A Pilot Instrument for Assessing Youth Well-Being

    Get PDF
    Extant measures of adolescent well-being in the United States typically focus on negative indicators of youth outcomes. Indices comprised of such measures paint bleak views of youth and orient action toward the prevention of problems over the promotion of protective factors. Their tendency to focus analyses at a state or county geographic scale produces limited information about localized outcome patterns that could inform policymakers, practitioners and advocacy networks. We discuss the construction of a new geo-referenced index of youth well-being based on positive indicators of youth development. In demonstrating the index for the greater Sacramento, California region of the United States, we find that overall youth well-being falls far short of an optimal outcome, and geographic disparities in well-being appear to exist across school districts at all levels of our analysis. Despite its limitations, the sub-county geographic scale of this index provides needed data to facilitate local and regional interventions
