Ways We Can Do Better: Bridging the Gap Between Gifted Education and Honors Colleges

Over the past decade of my academic career, I have increasingly noticed the gap between K–12 gifted education and honors college education as my research has forced me to straddle the two areas. My doctoral education at Ball State University included a specialization in gifted studies, which was a natural fit with my own interests in creative cognitive processes. During this time, I worked with a team that amassed a large data set from the honors college students, with twelve different measures ranging from topics of temperament to perfectionism to social dominance orientation. These measures addressed mostly psychosocial and emotional constructs, which are important considerations within K–12 gifted education. However, as I first began presenting and publishing findings from this data set, I noticed a gap between the conceptualizations of elementary, middle, and secondary-level gifted education and the function of honors colleges within higher education. This disconnect was further illuminated through my work at the Indiana University Center for Postsecondary Research, where I noticed that many of my colleagues from doctoral programs in higher education, in contrast to my own background in educational psychology, used different terminology to explain what seemed to be essentially parallel constructs. I also discovered extensive research on honors colleges and programs, which largely seemed to be separate from gifted education, i.e., published in different journals, presented at different conferences, and not often cited in one another’s works. Colangelo’s essay in this issue, “Gifted Education to Honors Education: A Curious History, a Vibrant Future,” presents an excellent description of many similarities between the two fields while Guzy’s “Honors is a Good Fit for Gifted Students—Or Maybe Not” points out some of the distinctions we should keep in mind. Given the important points in these essays, along with my own personal experiences spanning the two fields, I have generated three general suggestions for how my fellow researchers might better address the disconnect between gifted and honors education

Social Stress in Honors College Students: How Personality Traits, Perfectionism, Creativity, and Gender Predict Use of Social Coping Strategies

Much research has focused on how gifted children and adolescents deal with the social stigmas associated with giftedness. Previous studies indicate that several coping strategies exist, and these are related to personality and other characteristics. However, once these gifted individuals enter higher education, they are often required to shift their coping strategies to deal with stressors and situations in this new environment. This study investigates social coping strategies among honors college undergraduate students, looking at the need for updating the factor structure of a measure of social coping designed for and used with middle and high school students. Results suggest some variation in strategies for the honors college students. Additional results explore how personality traits, creativity, perfectionism, and other demographic characteristics predict the use of certain social coping strategies. This information can be used to mitigate the experience of social stress for this unique student population and address their needs through a supportive and accommodating environment

Achievement Goal Orientation as a Predictor of High-Impact Practice Participation for Postsecondary Students

Achievement goal orientation has been studied within education for decades, and previous research has linked the construct to student achievement and engagement. This study uses the 2x2 achievement goal orientation as a framework for exploring high-impact practice (HIP) participation for approximately 8,000 college students across 15 different institutions participating in the National Survey of Student Engagement (NSSE). Through a series of binary logistic regression analyses, results suggest students who employ a mastery-approach orientation are more likely to partake in a variety of beneficial HIPs, such as learning communities, research with faculty, service learning, study abroad, culminating experience, and formal leadership roles. Results for the remaining achievement goal orientations were more mixed, with some positively predicting HIP participation and others emerging as negative predictors

Planetary Candidates Observed by Kepler VI: Planet Sample from Q1-Q16 (47 Months)

\We present the sixth catalog of Kepler candidate planets based on nearly 4 years of high precision photometry. This catalog builds on the legacy of previous catalogs released by the Kepler project and includes 1493 new Kepler Objects of Interest (KOIs) of which 554 are planet candidates, and 131 of these candidates have best fit radii <1.5 R_earth. This brings the total number of KOIs and planet candidates to 7305 and 4173 respectively. We suspect that many of these new candidates at the low signal-to-noise limit may be false alarms created by instrumental noise, and discuss our efforts to identify such objects. We re-evaluate all previously published KOIs with orbital periods of >50 days to provide a consistently vetted sample that can be used to improve planet occurrence rate calculations. We discuss the performance of our planet detection algorithms, and the consistency of our vetting products. The full catalog is publicly available at the NASA Exoplanet Archive.Comment: 18 pages, to be published in the Astrophysical Journal Supplement Serie

Targeting HOX transcription factors in prostate cancer

YesBackground: The HOX genes are a family of transcription factors that help to determine cell and tissue identity during early development, and which are also over-expressed in a number of malignancies where they have been shown to promote cell proliferation and survival. The purpose of this study was to evaluate the expression of HOX genes in prostate cancer and to establish whether prostate cancer cells are sensitive to killing by HXR9, an inhibitor of HOX function. Methods: HOX function was inhibited using the HXR9 peptide. HOX gene expression was assessed by RNA extraction from cells or tissues followed by quantitative PCR, and siRNA was used to block the expression of the HOX target gene, cFos. In vivo modelling involved a mouse flank tumour induced by inoculation with LNCaP cells. Results: In this study we show that the expression of HOX genes in prostate tumours is greatly increased with respect to normal prostate tissue. Targeting the interaction between HOX proteins and their PBX cofactor induces apoptosis in the prostate cancer derived cell lines PC3, DU145 and LNCaP, through a mechanism that involves a rapid increase in the expression of cFos, an oncogenic transcription factor. Furthermore, disrupting HOX/PBX binding using the HXR9 antagonist blocks the growth of LNCaP tumours in a xenograft model over an extended period. Conclusion: Many HOX genes are highly over-expressed in prostate cancer, and prostate cancer cells are sensitive to killing by HXR9 both in vitro and in vivo. The HOX genes are therefore a potential therapeutic target in prostate cancer.The authors gratefully acknowledge the support of the Prostate Project charity (UK)

Children’s and adolescents’ rising animal-source food intakes in 1990–2018 were impacted by age, region, parental education and urbanicity

Animal-source foods (ASF) provide nutrition for children and adolescents’ physical and cognitive development. Here, we use data from the Global Dietary Database and Bayesian hierarchical models to quantify global, regional and national ASF intakes between 1990 and 2018 by age group across 185 countries, representing 93% of the world’s child population. Mean ASF intake was 1.9 servings per day, representing 16% of children consuming at least three daily servings. Intake was similar between boys and girls, but higher among urban children with educated parents. Consumption varied by age from 0.6 at <1 year to 2.5 servings per day at 15–19 years. Between 1990 and 2018, mean ASF intake increased by 0.5 servings per week, with increases in all regions except sub-Saharan Africa. In 2018, total ASF consumption was highest in Russia, Brazil, Mexico and Turkey, and lowest in Uganda, India, Kenya and Bangladesh. These findings can inform policy to address malnutrition through targeted ASF consumption programmes.publishedVersio

Incident type 2 diabetes attributable to suboptimal diet in 184 countries

The global burden of diet-attributable type 2 diabetes (T2D) is not well established. This risk assessment model estimated T2D incidence among adults attributable to direct and body weight-mediated effects of 11 dietary factors in 184 countries in 1990 and 2018. In 2018, suboptimal intake of these dietary factors was estimated to be attributable to 14.1 million (95% uncertainty interval (UI), 13.8–14.4 million) incident T2D cases, representing 70.3% (68.8–71.8%) of new cases globally. Largest T2D burdens were attributable to insufficient whole-grain intake (26.1% (25.0–27.1%)), excess refined rice and wheat intake (24.6% (22.3–27.2%)) and excess processed meat intake (20.3% (18.3–23.5%)). Across regions, highest proportional burdens were in central and eastern Europe and central Asia (85.6% (83.4–87.7%)) and Latin America and the Caribbean (81.8% (80.1–83.4%)); and lowest proportional burdens were in South Asia (55.4% (52.1–60.7%)). Proportions of diet-attributable T2D were generally larger in men than in women and were inversely correlated with age. Diet-attributable T2D was generally larger among urban versus rural residents and higher versus lower educated individuals, except in high-income countries, central and eastern Europe and central Asia, where burdens were larger in rural residents and in lower educated individuals. Compared with 1990, global diet-attributable T2D increased by 2.6 absolute percentage points (8.6 million more cases) in 2018, with variation in these trends by world region and dietary factor. These findings inform nutritional priorities and clinical and public health planning to improve dietary quality and reduce T2D globally.publishedVersio

Genetic variation at CYP3A is associated with age at menarche and breast cancer risk : a case-control study

Abstract Introduction We have previously shown that a tag single nucleotide polymorphism (rs10235235), which maps to the CYP3A locus (7q22.1), was associated with a reduction in premenopausal urinary estrone glucuronide levels and a modest reduction in risk of breast cancer in women age ≤50 years. Methods We further investigated the association of rs10235235 with breast cancer risk in a large case control study of 47,346 cases and 47,570 controls from 52 studies participating in the Breast Cancer Association Consortium. Genotyping of rs10235235 was conducted using a custom Illumina Infinium array. Stratified analyses were conducted to determine whether this association was modified by age at diagnosis, ethnicity, age at menarche or tumor characteristics. Results We confirmed the association of rs10235235 with breast cancer risk for women of European ancestry but found no evidence that this association differed with age at diagnosis. Heterozygote and homozygote odds ratios (ORs) were OR = 0.98 (95% CI 0.94, 1.01; P = 0.2) and OR = 0.80 (95% CI 0.69, 0.93; P = 0.004), respectively (P trend = 0.02). There was no evidence of effect modification by tumor characteristics. rs10235235 was, however, associated with age at menarche in controls (P trend = 0.005) but not cases (P trend = 0.97). Consequently the association between rs10235235 and breast cancer risk differed according to age at menarche (P het = 0.02); the rare allele of rs10235235 was associated with a reduction in breast cancer risk for women who had their menarche age ≥15 years (ORhet = 0.84, 95% CI 0.75, 0.94; ORhom = 0.81, 95% CI 0.51, 1.30; P trend = 0.002) but not for those who had their menarche age ≤11 years (ORhet = 1.06, 95% CI 0.95, 1.19, ORhom = 1.07, 95% CI 0.67, 1.72; P trend = 0.29). Conclusions To our knowledge rs10235235 is the first single nucleotide polymorphism to be associated with both breast cancer risk and age at menarche consistent with the well-documented association between later age at menarche and a reduction in breast cancer risk. These associations are likely mediated via an effect on circulating hormone levels
