It is often assumed that consumers’ willingness to pay (WTP) for eco-labeled products in research settings is not because of a desire for environmental protection, but rather that they are socially compelled to make decisions that reflects favorably on them, limiting the validity of findings. Using a second-price Vickrey experimental auction, this study found higher WTP for an eco-labeled product than a comparable good, but that social desirability bias, measured by the Marlowe–Crowne Social Desirability Scale, was not a significant predictor of WTP. Instead, environmental consciousness, environmental knowledge, education, and available information were stronger predictors of WTP for eco-labeled goods.
This study assessed the extent to which women's preconception binge drinking, tobacco use and cannabis use, reported prospectively in adolescence and young adulthood, predicted use of these substances during pregnancy and at 1 year postpartum.
Data were pooled from two intergenerational cohort studies: the Australian Temperament Project Generation 3 Study (395 mothers, 691 pregnancies) and the Victorian Intergenerational Health Cohort Study (398 mothers, 609 pregnancies). Alcohol, tobacco and cannabis use were assessed in adolescence (13–18 years), young adulthood (19–29 years) and at ages 29–35 years for those transitioning to parenthood. Exposures were weekly or more frequent preconception binge drinking (5 + drinks in one session), tobacco use and cannabis use. Outcomes were any alcohol, tobacco and cannabis use prior to awareness of the pregnancy, after awareness of pregnancy (up to and including the third trimester pregnancy) and at 1 year postpartum.
Frequent preconception binge drinking, tobacco use and cannabis use across both adolescence and young adulthood were strong predictors of continued use post-conception, before and after awareness of the pregnancy and at 1 year postpartum. Substance use limited to young adulthood also predicted continued use post-conception.
Persistent alcohol, tobacco use and cannabis use that starts in adolescence has a strong continuity into parenthood. Reducing substance use in the perinatal period requires action well before pregnancy, commencing in adolescence and continuing into the years before conception and throughout the perinatal period.
Rates of common mental health problems (depression/anxiety) rise sharply in adolescence and peak in young adulthood, often coinciding with the transition to parenthood. Little is known regarding the persistence of common mental health problems from adolescence to the perinatal period in both mothers and fathers.
A total of 393 mothers (686 pregnancies) and 257 fathers (357 pregnancies) from the intergenerational Australian Temperament Project Generation 3 Study completed self-report assessments of depression and anxiety in adolescence (ages 13–14, 15–16, 17–18 years) and young adulthood (ages 19–20, 23–24, 27–28 years). The Edinburgh Postnatal Depression Scale was used to assess depressive symptoms at 32 weeks pregnancy and 12 months postpartum in mothers, and at 12 months postpartum in fathers.
Most pregnancies (81%) in which mothers reported perinatal depression were preceded by a history of mental health problems in adolescence or young adulthood. Similarly, most pregnancies (83%) in which fathers reported postnatal depression were preceded by a preconception history of mental health problems. After adjustment for potential confounders, the odds of self-reporting perinatal depression in both women and men were consistently higher in those with a history of persistent mental health problems across adolescence and young adulthood than those without (ORwomen 5.7, 95% CI 2.9–10.9; ORmen 5.5, 95% CI 1.03–29.70).
Perinatal depression, for the majority of parents, is a continuation of mental health problems with onsets well before pregnancy. Strategies to promote good perinatal mental health should start before parenthood and include both men and women.
Maternal mental health during pregnancy and postpartum predicts later emotional and behavioural problems in children. Even though most perinatal mental health problems begin before pregnancy, the consequences of preconception maternal mental health for children's early emotional development have not been prospectively studied.
We used data from two prospective Australian intergenerational cohorts, with 756 women assessed repeatedly for mental health problems before pregnancy between age 13 and 29 years, and during pregnancy and at 1 year postpartum for 1231 subsequent pregnancies. Offspring infant emotional reactivity, an early indicator of differential sensitivity denoting increased risk of emotional problems under adversity, was assessed at 1 year postpartum.
Thirty-seven percent of infants born to mothers with persistent preconception mental health problems were categorised as high in emotional reactivity, compared to 23% born to mothers without preconception history (adjusted OR 2.1, 95% CI 1.4–3.1). Ante- and postnatal maternal depressive symptoms were similarly associated with infant emotional reactivity, but these perinatal associations reduced somewhat after adjustment for prior exposure. Causal mediation analysis further showed that 88% of the preconception risk was a direct effect, not mediated by perinatal exposure.
Maternal preconception mental health problems predict infant emotional reactivity, independently of maternal perinatal mental health; while associations between perinatal depressive symptoms and infant reactivity are partially explained by prior exposure. Findings suggest that processes shaping early vulnerability for later mental disorders arise well before conception. There is an emerging case for expanding developmental theories and trialling preventive interventions in the years before pregnancy.
The vortex of the twentieth century, the late 1930s and early to mid 1940s, provides an appropriate setting for Jennifer Egan's experiment in historical fiction. Many popular histories have glorified the bands of brothers and Rosie the Riveters of the so-called greatest generation. The best fiction and poetry of the 1940s offered a different, unflattering view. Journalists from that era—Martha Gellhorn, for one—said they needed fiction to get the history right (313). Literary treatments of the war focus on its incommunicability and on the crisis of meaning it inspired, but they have been vastly overshadowed by popular history books, documentaries, movies, and television shows that depend for their very production and distribution on an appeal to the fantasies that the contemporary war literature contradicts. In a decade when the idea of making America great again seems supercharged by notions of America when it was supposedly great, we can use some diving into the wreck.
OBJECTIVES/SPECIFIC AIMS: Expanded Access is an avenue for patients with no available treatment options to access investigational drugs and devices for clinical therapy. This process requires physicians treating these patients to submit requests to the FDA and the local IRB, processes which are typically unfamiliar to clinicians. METHODS/STUDY POPULATION: With the goal of reducing burden and ensuring access to investigational products, Michigan Medicine established the Expanded Access Oversight Committee in January 2015. This committee brought together key stakeholders to develop appropriate policy and infrastructure to support these requests. RESULTS/ANTICIPATED RESULTS: Outcomes from this committee have resulted in a uniform process with a single point of entry for interested physicians and patients. With standardized policy implemented across the institution, a revised IRB application has been developed that is more tailored to Expanded Access and an informed consent document has been developed specific to the clinical use of investigational therapies. To ensure timely execution of these agreements, the contracts office has streamlined the process for negotiating Expanded Access agreements with manufacturing companies. Further development has begun with the Michigan Clinical Research Unit to provide space for clinical visits in Expanded Access cases, allowing for initiation of outpatient therapy. These changes have allowed Michigan Medicine to support triple the number of Expanded Access requests, including more than 45 Expanded Access requests in fiscal year 2018. DISCUSSION/SIGNIFICANCE OF IMPACT: Institutional support for Expanded Access requests within a large academic medical center is feasible and can increase access to investigational therapies bfor patients.
Simplicity of construction and operation are advantages of iTMC (ionic transition metal complex) OLEDs compared with multi-layer OLED devices. Unfortunately, lifetimes do not compare favorably with the best multi-layer devices. We have previously shown for Ru(bpy)3(PF6)2 based iTMC OLEDs that electrical drive produces emission-quenching dimers of the active species. We report evidence here that a chemical process may also be implicated in degradation of devices based on Ir(ppy)2(dtb-bpy)PF6 albeit by a very different mechanism. It appears that degradation of operating devices made with this Ir-based complex is related to current-induced heating of the organic layer, resulting in loss of the dtb-bpy ligand. (The dtb-bpy ligand is labile compared with the cyclometallated ppy ligands.) Morphological changes observed in electrically driven Ir(ppy)2(dtb-bpy)PF6 OLEDs provide evidence of substantial heating during device operation. Evidence from UV-vis spectra in the presence of an electric field as well as MALDI-TOF mass spectra of the OLED materials before and after electrical drive add support for this model of the degradation process.
The Harlem Renaissance (1918–1937) was the most influential single movement in African American literary history. Its key figures include W. E. B. Du Bois, Nella Larsen, Zora Neale Hurston, Claude McKay, and Langston Hughes. The movement laid the groundwork for all later African American literature, and had an enormous impact on later black literature world-wide. With chapters by a wide range of well-known scholars, this 2007 Companion is an authoritative and engaging guide to the movement. It first discusses the historical contexts of the Harlem Renaissance, both national and international; then presents original discussions of a wide array of authors and texts; and finally treats the reputation of the movement in later years. Giving full play to the disagreements and differences that energized the renaissance, this Companion presents a set of new readings encouraging further exploration of this dynamic field.
The Harlem Renaissance – what a complex and conflicted aura the term evokes! People can scarcely agree on what it means. A vogue. A blossoming. A failure. A foundation. A few stars. A movement of black self-assertion against white supremacy, connected with anticolonial movements worldwide, or a local phenomenon gradually co-opted and destroyed by white voyeurs, cultural colonialists taking advantage of black naifs, opportunists, or weak-kneed bourgeois artists. A post hoc invention of cultural historians, now abundantly exploited by publishers, New York tour guides, and even, of late, real estate investors.
What is commonly called the Harlem Renaissance today was known as the Negro Renaissance in its own time. “Negro”: a word of pride, of strong vowels and a capital N. The thick diagonal strode forward and put its foot down. “Negro” no longer signifies to most people what it did in the early to mid-twentieth century. A Spanish derivative, it did not exactly mean “Black” in American English – it was sui generis, a word only used to indicate persons of the slightest (non-“white”) sub-Saharan African descent, regardless of color, but it seized on the essential meaning of the metaphor of the one mighty “drop [of blood]” that made one “black.” Racial segregation was racing toward its apogee. Race was the word of the hour. Race suicide. Race purity. Race man. Race woman. The Passing of the Great Race. “Arise, O Mighty Race!” Enter the New Negro.
While the location and duration of the movement popularly known as the Harlem Renaissance remain highly contested, its importance in the development of African American literature - and “modernism” in general - is more widely accepted today than ever. Central to the movement then known as the “Negro Renaissance” was the effort of black writers and artists after World War I to re-conceptualize “the Negro” independent of white myths and stereotypes that had affected African Americans' own relationship to their heritage and each other - independent, too, of Victorian moral values and bourgeois shame about those features of African American life that whites might take to confirm racist beliefs. The struggle with onedimensional mainstream stereotypes was, of course, far from over, and it was hardly new; a central feature of the work of Frances E.W. Harper and Charles Chesnutt in the 1890s, it played a major role in such novelistic “forerunners” to “renaissance” fiction as James Weldon Johnson's Autobiography of an Ex-Coloured Man and W. E. B. Du Bois's The Quest of the Silver Fleece.
It has been claimed that many Native American skeletons from the King site in Georgia show evidence of wounds from sharp-edged metal weapons that were wielded by members of the sixteenth-century de Soto expedition (Blakely and Mathews 1990). The supposed massacre of these villagers has caught the attention of the public and scholars alike. But we failed to find any evidence of damage caused by sixteenth-century Spanish weapons in our examination of the King site skeletons. Our finding-there is no evidence for a massacre-eliminates a major discrepancy between historical and archaeological information used in reconstructions of the de Soto route.
