- We describe and compare the expected performance trajectories of older adults on the Mini-Mental Status Examination (MMSE) across six independent studies from four countries in the context of a collaborative network of longitudinal studies of aging. A coordinated analysis approach is used to compare patterns of change conditional on sample composition differences related to age, sex, and education. Such coordination accelerates evaluation of particular hypotheses. In particular, we focus on the effect of educational attainment on cognitive decline. Regular and Tobit mixed models were fit to MMSE scores from each study separately. The effects of age, sex, and education were examined based on more than one centering point. Findings were relatively consistent across studies. On average, MMSE scores were lower for older individuals and declined over time. Education predicted MMSE score, but, with two exceptions, was not associated with decline in MMSE over time. A straightforward association between educational attainment and rate of cognitive decline was not supported. Thoughtful consideration is needed when synthesizing evidence across studies, as methodologies adopted and sample characteristics, such as educational attainment, invariably differ.

- Rationale: Idiopathic pulmonary fibrosis (IPF) is a chronic dysregulated response to alveolar epithelial injury with differentiation of epithelial cells and fibroblasts into matrix-secreting myofibroblasts resulting in lung scaring. The prognosis is poor and there are no effective therapies or reliable biomarkers. Galectin-3 is a beta-galactoside binding lectin that is highly expressed in fibrotic tissue of diverse etiologies. Objectives: To examine the role of galectin-3 in pulmonary fibrosis. Methods: We used genetic deletion and pharmacologic inhibition in well-characterized murine models of lung fibrosis. Further mechanistic studies were performed in vitro and on samples from patients with IPF. Measurements and Main Results: Transforming growth factor (TGF)-beta and bleomycin-induced lung fibrosis was dramatically reduced in mice deficient in galectin-3, manifest by reduced TGF-beta 1 induced EMT and myofibroblast activation and collagen production. Galectin-3 reduced phosphorylation and nuclear translocation of beta-catenin but had no effect on Smad2/3 phosphorylation. A novel inhibitor of galectin -3, TD139, blocked TGF-beta-induced beta-catenin activation in vitro and in vivo and attenuated the late-stage progression of lung fibrosis after bleomycin. There was increased expression of galectin-3 in the bronchoalveolar lavage fluid and serum from patients with stable IPF compared with nonspecific interstitial pneumonitis and controls, which rose sharply during an acute exacerbation suggesting that. galectin-3 may be a marker of active fibrosis in IPF and that strategies that block galectin-3 may be effective in treating acute fibrotic exacerbations of IPF. Conclusions: This study identifies galectin-3 as an important regulator of lung fibrosis and provides a proof of principle for galectin-3 inhibition as a potential novel therapeutic strategy for IPF.

- Command & Control (C2) is required for safe and effective maritime operations. To facilitate effective decision-making and C2, it is essential that the crew can access the required information. It is therefore essential that the appropriate information architecture is used. Navigation, being an essential aspect of C2, has seen a radical change from paper charts and individual instruments to computer systems capable of sophisticated data fusion to provide enhanced situational awareness. The development of the required information architecture is not a software/engineering issue, but rather lies within the human factors domain as it requires an understanding of how humans perceive information, how they use mental models and subsequently make safe and effective decisions. © 2013: The Royal Institution of Naval Architects.

The Politics of Legal Challenges to Pornography: Canada, Sweden, and the United States
- 2014
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The dissertation analyzes obstacles and potential in democracies, specifically Canada, Sweden, and United States, to effectively address empirically documented harms of pornography. Legislative and judicial challenges under different democratic and legal frameworks are compared.Adopting a problem-driven theoretical approach, the reality of pornography’s harms is analyzed. Evidence shows its production exploits existing inequalities among persons typically drawn from other forms of prostitution who suffer multiple disadvantages, such as extreme poverty, childhood sexual abuse, and race and gender discrimination, making survival alternatives remote. Consumption is also divided by sex. A majority of young adult men consumes pornography frequently; women rarely do, usually not unless initiated by others. After consumption, studies show many normal men become substantially more sexually aggressive and increasingly trivialize and support violence against women. Vulnerable populations—including battered, raped, or prostituted women—are most harmed as a result.The impact of attempts to address pornography’s harms on democratic rights and freedoms, specifically gender equality and speech, is explored through the case studies. Democracies are found to provide more favorable conditions for legal challenges to pornography’s harms when recognizing substantive (not formal) equality in law, and when promoting representation of perspectives and interests of groups particularly injured by pornography. State-implemented approaches such as criminal obscenity laws are found less effective. More victim-centered and survivor-initiated civil rights approaches would be more responsive and remedial—a finding with implications for other politico-legal problems, such as global warming, that disproportionately affect disadvantaged populations traditionally largely excluded from decision-making.
