Factors associated with body size perception among adolescent goal-oriented sports participants and non-participants : a cross-sectional Finnish study

2022

Abstract Background Regardless of competitive athletes’ body image pressures, only few studies have focused on adolescent sport participants’ body image and the findings are inconclusive. Furthermore, the role of competitive goals in sports on adolescents’ body size perception has not been studied. We examined the factors associated with adolescents’ competitive goals in sports and body size perception, and the associations between adolescents’ competitive goals in sports and body size perception. Methods The cross-sectional study consisted of 475 goal-oriented sports club participants and 936 reference youths (aged 14–16 years). The study questionnaire included multiple choice items on hea…

Beyond lifetime reproductive success: the posthumous reproductive dynamics of male Trinidadian guppies

2013

In semelparous populations, dormant germ banks (e.g. seeds) have been proposed as important in maintaining genotypes that are adaptive at different times in fluctuating environments. Such hidden storage of genetic diversity need not be exclusive to dormant banks. Genotype diversity may be preserved in many iteroparous animals through sperm-storage mechanisms in females. This allows males to reproduce posthumously and increase the effective sizes of seemingly female-biased populations. Although long-term sperm storage has been demonstrated in many organisms, the understanding of its importance in the wild is very poor. We here show the prevalence of male posthumous reproduction in wild Trini…

Management of undescended testes: European Association of Urology/European Society for Paediatric Urology Guidelines.

2016

Summary Context Undescended testis is the most common endocrinological disease in the male newborn period. Incidence varies between 1.0% and 4.6% in full-term neonates, with rates as high as 45% in preterm neonates. Failure or delay of treatment can result in reduced fertility and/or increased testicular cancer risk in adulthood. Objective To provide recommendations for the diagnosis and treatment of boys with undescended testes which reduce the risk of impaired fertility and testicular cancer in adulthood. Evidence acquisition Embase and Pubmed were searched for all relevant publications, from 1990 to 2015 limited to English language. Data were narratively synthesized in light of methodolo…

Epidemiology, prevention and screening for prostate cancer.

1996

Prostate cancer is a growing social problem. The economical impact is high and is likely to become greater in future years, not only because the number of patients diagnosed with prostatic neoplasias is increasing steadily, but also because of the promotion of screening programmes and the rise in the number of surgical procedures available. It can be concluded that, at the present stage, widespread implementation of screening cannot be recommended. The answer to the question of screening can only be provided by large randomised trials, comparing either screening versus no screening, or early versus delayed treatment in patients in whom early cancer is detected by screening.

Symptomatology and Diagnosis of Benign Prostatic Hyperplasia

1991

The symptoms of benign prostatic hyperplasia are well known. Diagnosis rests on digital palpation of the enlarged prostate. Objective parameters are laboratory tests, imaging techniques, endoscopy, and urodynamic investigations. Laboratory tests include urinalysis and serum creatinine measurement. Markers are not reliable and the determination of acid phosphatase and prostate-specific antigen is not recommended routinely for patients with prostatism. Imaging techniques are usually restricted to a complete echographic investigation of the entire urinary tract. Endoscopic manipulations are seldom necessary. Uroflow measurements are customarily performed, but the need for a complete urodynamic…

Effects of Aerodynamic Drag and Drafting on Propulsive Force and Oxygen Consumption in Double Poling Cross-country Skiing

2022

Purpose To investigate the effects of aerodynamic drag and drafting on propulsive force (FPROP), drag area (CDA), oxygen cost (V˙O2), metabolic rate (E˙) and heart rate (HR) during roller skiing on a treadmill in a wind tunnel using the double poling technique. A secondary aim was to investigate the effects of wind versus no-wind test conditions on the same physiological parameters. Methods 10 subjects of each gender participated in the experiments. One pair of skiers of the same gender roller skied simultaneously in line with the air flow; the distance between the skiers was ~2.05 m. Each pair was tested as follows: I) with wind, leading; II) with wind, drafting; III) without wind. The tre…

La poesía como lección de historia, Matei Vişniec, «En la mesa con Marx» («La masă cu Marx»)La poesía como lección de historia, Matei Vişniec, «En la…

2017

After a brief presentation describing the main traits of the literary Romanian exile, this article aims to reveal some aspects of Matei Vişniec’s poetical originality, a Romanian francophone writer who defines himself as a «lucky exiled man». The poem we’ve chosen, «At the table with Marx» («La masă cu Marx»), involves the main line of the book with the same title that was published in Romania in 2011. His explicitly political regard relates him to another text that circulated as an anti-communist manifesto during the previous years of the communist dictature fall: the well-known poem entitled «The sailing ship» («Corabia»). A parable of complicity and colective guiltiness, «At the table wi…

Paredzošā stimulētā mācīšanās

2016

Continuous actor-critic learning automaton, jeb CACLA, algoritma aktiera un kritiķa komponentes ir apvienojamas vienā, izmantojot faktu, ka tās no stāvokļu telpas izgūst līdzīgas pazīmes savu funkciju veikšanai. Tas ļauj divas reizes samazināt to realizēšanā izmantotā neironu tīkla trenējamo parametru skaitu, kā arī ļauj aģentam ātrāk nonāk pie labas stratēģijas, jo optimālās stratēģijas funkcijas parametri tiek pielāgoti arī vērtību funkcijas izmaiņu rezultātā. Tas noved pie savdabīga optimālās stratēģijas funkcijas parametru nepārraudzītās mācīšanās procesa. Šāds netiešā veidā veikts optimālās stratēģijas funkcijas parametru pielāgošanas process atstāj ietekmi uz trenēšanas procesu, jo sa…

Непрерывные функции на топологических пространствах

1986

Сборник посвящен проблемам топологии и функциональ­ного анализа. В сборник включены работы, посвященные исследованию непрерывных функций на топологических и нечетких топологических, а также структуры топологических пространств. В ряде работ рассматриваются непрерывные функции, заданные на специальных топологических пространствах ­ метрическом, нормированном и др.
