Emotional Symptoms and Dietary Patterns in Early Adolescence: A School-Based Follow-up Study
No full textObjective To examine the relationship between early emotional symptoms and dietary patterns over 3 years in a school-based sample. Design Three-year longitudinal prospective study. Setting Thirteen schools in Reus, Spain. Participants From a sample of 562 preadolescents with and without emotional symptoms, 165 were observed and were classified as either showing (n = 100) or not showing emotional symptoms (n = 65). Main Outcome Measure Emotional symptoms were assessed at baseline and after 1 and 3 years. In the third year, data were collected on food consumption, adherence to the Mediterranean diet (MD), and physical activity. Analysis Dietary patterns were created by principal component analysis. Multivariate logistic regression was conducted with P < .05 considered significant. Results Girls with emotional symptoms scored significantly lower in assessments for MD (score of 5.41 ± 2.19) and physical activity (score of 4.97 ± 2.05) than did girls who had no emotional symptoms (scores: MD, 6.19 ± 1.67; physical activity: 5.86 ± 1.94). Approximately 39.68% of girls with emotional symptoms showed high adherence to a sweet and fatty food pattern. After adjusted logistic regression, girls with emotional symptoms were 4 times as likely to have high adherence to a sweet and fatty food pattern (odds ratio, 4.79; 95% confidence interval, 1.55–15.10). No differences were observed among boys. Conclusions and Implications Girls with emotional symptoms during early adolescence have high adherence to a pattern rich in sweet and fat foods and low adherence to MD, and engage in low levels of physical activity. These findings highlight the importance of managing emotional distress to prevent it from having a negative effect on eating behavior. © 2017 Society for Nutrition Education and Behavio
A two-phase population study: relationships between overweight, body composition and risk of eating disorders.
No full textBACKGROUND: Overweight and eating disorder (ED) are major public health problems in adolescents. Aims: To assess the association of overweight, body composition and anthropometric characteristics with the probability being at risk of ED.
METHODS: A two-phase study was used. 329 girls and 96 boys (aged 12-18 years) from an initial sample of 2967 adolescents were studied. The BMI, percentage of fat mass estimated by bioimpedance (FM(BIA)), waist circumference, waist-to-height ratio, and waist-to-hip ratio (WHipr) were calculated. The Eating Attitudes Test, Youth's Inventory-4 and a questionnaire to evaluate social influences were administered.
RESULTS: A total of 34.7% of girls and 53.6% of boys at risk of ED were overweight (including obesity). For girls, overweight frequency was significantly higher in risk ED group than in control group. Increases of one point in the BMI or FM(BIA) increased the probability of being at risk of ED by 12% (3.0-19.0) and 4% (0.0-8.0), respectively. An increase in WHipr was negatively associated with ED risk. Smoking and symptoms of dysthymia and the genralized anxiety disorder also increase the probability of being at risk of ED in adolescent girls. In adolescent boys, these relations were not observed.
CONCLUSIONS: The higher BMI and the percentage of FM(BIA) are associated with greater risk of ED in adolescent girls, when psychological factors are present. Increases in the WHipr, characteristic of childhood body is negatively associated with that risk
Effects of prenatal exposure to multiple heavy metals on infant neurodevelopment: A multi-statistical approach
No full textPrenatal exposure to heavy metals poses risks to fetal brain development, yet the joint effects of these metals remain unclear, with inconsistent findings across statistical models. This study investigates the joint effect of prenatal exposure to cadmium (Cd), nickel (Ni), mercury (Hg), and lead (Pb) on infant neurodevelopment using various statistical approaches. The study included 400 mother-infant pairs. Heavy metal levels were measured in maternal urine samples at the 12th week of gestation, and infant neurodevelopment at 40 days was evaluated by the Bayley Scales of Infant and Toddler Development. Generalized Additive Models (GAM), Multivariable Linear Regression (MLR) with restricted cubic spline (RCS), Bayesian Kernel Machine Regression (BKMR), and Weighted Quantile Sum (WQS) regression were applied to explore the associations between heavy metal exposure and neurodevelopmental outcomes. GAM revealed a significant linear relationship for Cd with cognitive scale (p = 0.045) and expressive language (p = 0.043). MLR confirmed that Cd was negatively associated with both cognitive scale (β = −1.47, p = 0.044) and expressive language (β = −0.32, p = 0.019) and RCS presented a non-linear association between Pb and language scale (p = 0.001). BKMR suggested a negative but non-significant association with most outcomes. WQS indicated a significant adverse effect of metal mixture on expressive language (β = −0.26, 95% CI = −0.44, −0.07), identifying Cd and Ni as the primary contributors. Prenatal exposure to heavy metals have detrimental effects on infant neurodevelopment, especially on language development

Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
No full text“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Iron overload and metabolic disorders in humans
No full textContribuciones y conocimientos que aporta esta tesis El presente trabajo ha confirmado la asociación de las concentraciones elevadas de ferritina con el desarrollo de síndrome metabólico y con el criterio, hipertrigliceridemia, incluido en el diagnostico de síndrome metabólico; mientras que la asociación de ferritina con las concentraciones de colesterol de las HDL es más discutible. Metodología 1. Se realizó una revisión sistemática y metaanálisis de estudios observacionales que determinen la relación entre altos niveles de ferritina y síndrome metabólico desde 1966 hasta diciembre 2012. 2. Se realizó una revisión sistemática y metaanálisis de estudios observacionales que estudien la relación entre altos niveles de ferritina con hipertrigliceridemia, bajo HDL colesterol y LDL colesterol. El odds ratio de los estudios fue combinado utilizando un modelo de efectos aleatorios, ponderando por el inverso de la varianza. La heterogeneidad entre estudios se determinó utilizando el índice estadístico I2. Los sesgos de publicación fueron determinados mediante el gráfico en embudo o funnel plot. Se realizaron análisis de sensibilidad. Conclusiones Altos niveles de ferritina se asocian a la presencia del síndrome metabólico y también a la dislipidemia. El efecto de altos depósitos de hierro sobre estas alteraciones metabólicas necesita confirmarse con más estudios prospectivos. Además son necesarios que permitan identificar un valor de ferritina que se relacione con el aumento del riesgo de aparición de estas alteraciones metabólicas. Publicaciones: 1.

Využití sociálních médií v B2B prodeji
No full textTato diplomová práce se zabývá tím, jak mohou B2B obchodníci využívat sociální média v prodeji. Na základě systematické rešerše literatury, autor zjistil, že akademici, zkoumající danou problematiku, navrhují další výzkum, a to: v kterých konkrétních krocích se dají využít sociální média v prodeji (Salo, 2017). Autor se na základě toho rozhodl zjistit, jaké sociální sítě, různé technologie a pluginy se dají využít v B2B prodeji - tzv. social sellingu. Social selling se v této práci týká primárně procesu akvizice a okrajově péčí o stávající zákazníky. Autor si vybral kvalitativní průzkum pomocí 10 hloubkových polo-strukturovaných rozhovorů, aby odhalil jak, která sociální média to jsou, tak i motivaci prodejců, proč tato média používat/nepoužívat. Aby autor dodržel správnost vyhodnocení výsledků, data byla analyzována pomocí Tématické analýzy, která v této studii vykrystalizovala 2 hlavní strategické přístupy v social sellingu. Tyto přístupy (tzv. Push a Pull strategie) obsahují praktické příklady a konkrétní aktivity, které mohou prodejci využívat v každodenní praxi. Tyto výsledky jsou prezentovány s důrazem na praktičnost a jednoduchost implementace. Tvoří proto hlavní přínos autorovo výzkumu. V poslední části autor zmiňuje výzvy a manažerská doporučení, které mohou obchodníci využít v každodenním pracovním životě.This diploma thesis focuses on social media usage in B2B sales. Based on the systematic literature review conducted by the author, he has found out that recent researchers (Salo, 2017) suggest further research in the area of how and in which sales phase should various social networking sites, technologies and plugins used. To further fill this research gap, author decided to identify these social media and their usage among B2B salespeople in the so-called social selling process. The social selling process in this thesis applies mainly to acquiring new prospects and tangentially to taking care of existing clients (follow-up step). Author has chosen a qualitative research method via conducting 10 in-depth semi-structured interviews to reveal these instruments as well as motivation of a sales person on why to use social media in the selling process. The collected data was analyzed using Thematic analysis to ensure the right procedure and to identify main themes which crystalized into 2 main strategic approaches in social selling. These approaches (Push and Pull) include practical examples of concrete activities which sales people can use in their daily jobs and are presented with focus on practicality and ease of implementation. These also form the main contribution of author`s research. In the last part, author mentions challenges in social selling and recommended managerial implications for salesforce
TeX v jednoduchém unixovém prostředí
No full textsummary:Při ladění TeXového dokumentu potřebujeme mnohokrát opakovaně pouštět TeX, podívat se, jak dopadl výsledek v prohlížeči DVI nebo PDF souboru, mrknout na výpis TeXu na terminálu, podívat se případně do logu a celou činnost opakovat. V tomto článku je ukázáno, jak tuto práci dělá autor článku. Proces "editor-TeX-kuk" je zde podporován jednoduchými unixovými nástroji: bashovým skriptem texloop, který si autor pro tyto účely vytvořil, dále terminálem Xterm a jednoduchým editorem, který umí navázat na klávesovou zkratku spuštění příkazu v systému. Čtenář se zde může inspirovat a přizpůsobit tyto nástroje svým vlastním potřebám. V článku je popsána funkce skriptu texloop, dále je neformálně rozveden dlouholetý vývoj autorova vztahu k textovým editorům a konečně je zde uvedena konfigurace terminálu Xterm, aby vyhovoval českému prostředí jak v kódování ISO-8859-2, tak v kódování UTF-8. Pro kódování UTF-8 si v závěru článku vygenerujeme TeXový formát csplain.summary:By debugging a TeX document it is necessary many times repeatedly to run TeX, to look for the result in DVI or PDF file, to gander the TeX output on the terminal, or eventually to have a look in the log-file, and all that action to repeat. In the paper it is show, how this work is made by author. The process '‘'editor-TeX-look' is supported by simple Unix tools: bash script texloop, created by author for these purposes, Xterm terminal and a simple editor, which is able to link to the shortcut key the activation of a system command. The reader could be inspired with the solution and to adapt these tools to his/her own needs. In the paper the function of the texloop script is described, and further the longstanding evolution of the author's relation to text editors is informal elaborated and finally a configuration of Xterm terminal, suitable for the czech environment with both ISO-8859-2 and UTF-8 encoding is introduced. For UTF-8 encoding the TeX format csplain is generated at the end of the paper
