Edward Zigler pioneered and insisted upon the integration of science, practice, and policy development to support vulnerable children and families, reduce poverty, and improve US wellbeing, writ large. His far-reaching scholarship in turn critically shaped developmental science and US policy in multiple areas. This review reflects upon Zigler's influence on US child care, Head Start, Early Head Start, and prekindergarten programs. It describes the integration of one major area of developmental science, the field of attachment theory, research, and intervention, with US child care and early childhood education programs and policy. The integration of attachment into these systems not only epitomizes Zigler's overarching canon but also has improved services and advanced attachment theory and research. Throughout the review, I suggest next steps for leveraging attachment theory, research, and intervention to improve US child care and early childhood education systems in ways that both reflect and carry forward the legacy of Edward Zigler.

What shapes attitudes towards procedural rules that constrain executive power? This letter argues that procedural values are contextual: A function of who is in power. Supporters of those in power prefer fewer procedural constraints, while opposition supporters prefer greater. This study reports the results of a unique test using data from the 2016 Cooperative Congressional Election Survey. Respondents were asked, in both pre- and post-election waves, if they thought it should be ‘easier or harder for the president to keep documents secret from the public’. The panel design makes it possible to track individual changes following the shift in political context. The results show evidence of a partisan ‘flip’ in attitudes following the election, with Republicans becoming less likely – and Democrats more likely – to prefer additional constraints on presidential secrecy. However, this partisan ‘flip’ is present only among higher political knowledge respondents.

Anhedonia may be considered as a transnosological feature of depression and schizophrenia. The aim of the present study was to assess hedonic responses to sucrose solutions and sweet taste perception threshold in patients with major depression and in schizophrenic patients in comparison with healthy subjects (matched for age and gender with depressive patients), and to compare these responses to evaluations by the Physical and Social Anhedonia scale of Chapman and the Pleasure Scale of Fawcett, generally used to quantify anhedonia. Hedonic responses to sucrose solutions were similar in patients with major depression (n = 20), schizophrenia (n = 20), and healthy controls (n = 20). Sweet taste perception threshold was significantly higher in depressive patients than in controls. Hedonic response to sucrose was inversely correlated with physical Anhedonia Scores and sweet taste perception threshold with Pleasure Scale scores. Measures of hedonia/anhedonia were not related with the intensity of depression or anxiety as measured by the Montgomery-Asberg Depression Rating Scale (MADRS) and Hamilton Anxiety Scale, respectively. In 11 depressed patients hospitalised for 17 to 33 days, neither hedonic ratings to sucrose solutions, sweet taste perception threshold, Physical, Social Anhedonia scores nor Pleasure Scale scores were modified in spite of substantial decrease in MADRS or Hamilton Anxiety scores. Hedonic responses to sucrose solutions and sweet taste perception threshold may be used as complementary evaluation to quantify anhedonia.

In order to identify clinical and demographic variables that predict response to antidepressants and to analyse prediction of outcome as a function of definition of outcome we analysed pooled data of two independent, multicentre, double blind parallel group studies. Study I compared the efficacy of mianserin with that of fluoxetine in 65, and study II compared mianserin with fluvoxamine in 60 patients with depression. Improvement was defined as at least 20% decrease in MADRS by day 14. Patients were considered as responders if they had greater than 50% decrease and non-responders if they had ≤ 50% decrease from baseline in the MADRS at day 56. Complete remission was defined as MADRS score ≤ 6 at day 56. Patients' characteristics did not differ between mianserin and SSRI groups. Early improvement predicted response in 92% and complete remission in 55% of the patients improved at day 14. Multivariate forward stepwise logistic regression analysis showed that response to treatments at day 56 was significantly (P = 0.0003) associated with early improvement, age (responders had higher age than non-responders) and weight (responders weighted more than non-responders). Complete remission was only predicted by early improvement. Treatments could not be differentiated when data were analysed according to responder/nonresponder status or complete remission/no complete remission. However, when the same data were analysed by analysis of variance a significant treatment effect (P = 0.02, mianserin > SSRIs) and a quadratic type treatment by time interaction (P = 0.023) were found. The robustness of the analysis was further improved by inclusion of covariates (age, weight). Early clinical improvement seems to be the best predictor of 2 month response to antidepressants (mianserin, SSRIs). Younger age and lower weight may predict non-response. Quantitative analysis differentiates treatments better than analysis of responder status. As obtenation of complete remission is a realistic objective with current antidepressants, studies longer than 2 months are needed to assess effectiveness of these drugs in the obtenation of complete remission.

We investigated plasma cortisol in a psychological stress paradigm in seven weaned anhedonic alcoholics in comparison with seven age-matched healthy controls. Alcoholics had significantly higher mean plasma cortisol at baseline and no increase following a psychological stress paradigm. Anhedonic alcoholics judged the experimental situation less agreeable than controls. Anhedonic alcoholics may have blunted cortisol response to psychological stress.

Allele A1 of the TaqI A restriction fragment length polymorphism (RFLP) of the dopamine D2 receptor gene has been found to be associated with substance abuse and alcoholism. The personality trait of Novelty Seeking (NS) is also associated with substance abuse and dependence. We hypothesised, on the basis of involvement of dopaminergic mechanisms in substance abuse, that the presence of allele A1 of the dopamine D2 receptor gene may represent a genetic predisposition for the NS personality trait. We investigated, therefore, whether the allele A1 of the TaqI A RFLP of the dopamine D2 receptor gene is associated with the NS dimension of the Tridimensional Personality Questionnaire (TPQ) in healthy Caucasian subjects with no history of alcohol or substance abuse or dependence. We genotyped 204 subjects aged 18 to 30 years. There was no association between any of the alleles of the D2 receptor genes and any of the TPQ scores (NS, Harm Avoidance, Reward Dependence). We conclude that allele A1 of the TaqI A RFLP of the dopamine D2 receptor is not associated with NS personality trait in healthy Caucasian subjects.

Text readability assessment is a challenging interdisciplinary endeavor with rich practical implications. It has long drawn the attention of researchers internationally, and the readability models since developed have been widely applied to various fields. Previous readability models have only made use of linguistic features employed for general text analysis and have not been sufficiently accurate when used to gauge domain-specific texts. In view of this, this study proposes a latent-semantic-analysis (LSA)-constructed hierarchical conceptual space that can be used to train a readability model to accurately assess domain-specific texts. Compared with a baseline reference using a traditional model, the new model improves by 13.88% to achieve 68.98% of accuracy when leveling social science texts, and by 24.61% to achieve 73.96% of accuracy when assessing natural science texts. We then combine the readability features developed for the current study with general linguistic features, and the accuracy of leveling social science texts improves by an even higher degree of 31.58% to achieve 86.68%, and that of natural science texts by 26.56% to achieve 75.91%. These results indicate that the readability features developed in this study can be used both to train a readability model for leveling domain-specific texts and also in combination with the more common linguistic features to enhance the efficacy of the model. Future research can expand the generalizability of the model by assessing texts from different fields and grade levels using the proposed method, thus enhancing the practical applications of this new method.

Purpose: We identified key clinicopathologic features of brain metastasis (BM) patients who are long-term survivors (LTS). Methods: We screened a prospective database of 1892 patients (treated 2006-2017), identified 92 (5%) who lived > 3 years following BM diagnosis, and performed per patient analyses. Results: Median age at diagnosis of BM was 57 years (range 19-77), 77% were women. The most common tumors were lung (50%), breast (26%), thyroid (7%) and skin (5%). 42% had tumors with drug-targetable oncoproteins (e.g. EGFR mutant) and 15% expressed hormonal receptors. ECOG was <2 in 70%. 47% had stage IV disease at diagnosis (75% with brain as the first site). 55% had controlled extracranial disease at the time of BM diagnosis. Median BM diameter was 1.5 cm (range 0.2-7) and 62% had a single lesion. Treatment was with surgery, radiosurgery, whole brain radiation (WBRT), or systemic therapy alone in 38%, 62%, 52%, and 4%, respectively. 53% received targeted- or immuno-therapy. Median follow up was 63 months (range 36-113). 61% failed intracranially at a median 24 months (range 1-99). 5 and 10- year survival (from BM diagnosis) was 82%, and 34%, respectively. Neither upfront WBRT nor other variables tested correlated with improved survival. In patients who died, an MRI was available within 3 months from death in 57%; of those 55% had no active intracranial disease, suggesting that the majority of deaths were non-neurologic. Conclusion: In general, LTS of BM had a limited number of BM, inactive extracranial disease, and drug targetable mutations.
