The Relationship

The relationship between lens mass and age determined in 80 wild goats (Capra pyrenaica Schinz, 1838) from Sierra de Gredos (Avila), follows the equation Y = 79.36 + 259.94 log X, where Y is lens mass (mg) and X wild goat age (months). Lens masses of males and females do not differ significantly. Age-class (1-year classes) cannot be determined with 95% confidence from lens mass in animals 2 years and older. This method of age determination can be useful in cases where the age of young animals cannot be evaluated with accuracy otherwise; age determination by observation of teeth eruption or counting of growth rings of the horns is generally very valuable.

This work shows the value of osseous growth marks for age determination in two terrestrial chelonia, Testudo hermanni and Testudo graeca. Careful histological observation of long bones proves that concentric rings show a yearly growth pattern; we have already described similar findings in amphibians, snakes, and lizards.We confirm these data first by the observation of some wild turtles of known age and of a close correlation between the number of bone rings and the number of rings on the cornified scutes. We also confirm in both species that scutes have a yearly growth rhythm and we conclude that bone growth marks provide a good criterion for age determination. Resorption destroys some juvenile rings; we propose a calculation to evaluate the number of resorbed lines to obtain the true individual age.In our turtles, scute growth rings allowed age determination until sexual maturity. With osseous growth marks, we were able to extend accurate ageing until the 20th year. We also established that sexual maturity occurs when animals are 12 or 13 years old in both species, with little difference between males and females.

The present research analyzes the relationship between attachment styles at an adult age and field dependence in order to identify possible individual differences in information processing. The “Experience in Close Relationships” test of Brennan et al. was administered to a sample of 380 individuals (160 males, 220 females), while a subsample of 122 subjects was given the Embedded Figure Test to measure field dependence. Confirming the starting hypothesis, the results have shown that individuals with different attachment styles have a different way of perceiving the figure against the background. Ambivalent and avoidant individuals lie at the two extremes of the same dimension while secure individuals occupy the central part. Significant differences also emerged between males and females.

The Relationship

Introduction Binge eating is a common behaviour that is strongly linked to both obesity and eating disorder. There is evidence that binge eating commonly co-occurs with other problematic and addictive-like behaviours; however, this has not been explored systematically. The present study aimed to examine the relationship between binge eating, body weight, disordered eating behaviours and associated addictive-like behaviours, with particular attention paid to gender differences. Method A community sample ( N = 500; 75% female, Mage = 32.5 years) reported disordered eating behaviours (i.e. binge eating, purging, restriction of eating, compulsive exercise), body mass index (BMI), food addiction, starvation addiction, exercise dependence, tobacco use and alcohol consumption. Results 42% of females and 21% of males reported binge eating during the past four weeks. Binge eating was significantly associated with all investigated behaviours in females, and with purging, compulsive exercise and overweight/obesity in males. Controlling for BMI, self-starvation predicted binge eating in males (OR = 1.07), while food addiction (OR = 1.73) and alcohol dependence (OR = 1.11) predicted binge eating in females. Conclusions The multiple associations between binge eating and addictive-like behaviors supports broad screening and generalized prevention efforts. Prevention efforts should reflect gender differences.

Context. Occlusion in primary teeth varies among children of different populations and races. Aim. To assess and compare the occlusal characteristics and spacing in primary dentition among 3–6-year-old Dravidian children. Materials and Methods. The study included 2281 school going children. The primary molar relation, canine relation, overjet, and overbite were assessed using Foster and Hamilton criteria. Spacing conditions were registered according to Kisling and Krebs criteria. Results. The flush terminal plane molar relation (80.3%) was the most common primary molar relation. The distal step molar relation was more frequently found in female children (12.8%) than in males (8.6%). Class 1 canine relation was the most prevalent canine relation (81.3%) among males and females. Ideal overjet (84.3%) and overbite (72.7%) were observed among the majority of the children. Spaced type of arches occurred more frequently than closed arches in this sample. The incidence of primate spaces was more in males than in females. Conclusion. The study population has fewer deviations from normal occlusion which indicates decreased tendency for malocclusion in permanent dentition. However, further longitudinal studies are necessary to identify the potential limitations of a clinical approach relying on early orthodontic diagnosis and intervention.

Samples were taken from 284 ringed seals (Phoca hispida) in the Svalbard area during April–July 1981 and March–April 1982. The age of 283 seals was determined by reading annuli in the cementum of the canine teeth. The mean age of the males was 11.3 years, and of the females, 14.9 years. Females were found to be significantly older than males. The mean length of sexually mature ringed seals was 128.9 cm for both sexes. The mean weight of adult males and females was 53.5 and 61.4 kg, respectively. Females were found to be significantly heavier than males. The sex ratio was 47.8% males and 52.2% females. Studies of microscopic sections of testis and epididymis from ringed seal males showed that 63, 75, and 80% of 5-, 6-, and 7-year-old animals, respectively, were sexually mature. The weights of testis and epididymis, diameters of tubuli, and the size of testis all showed a marked increase in the 5-year age-class. Macroscopic sections of ovaries from ringed seal females showed that 20, 60, and 80% of 3-, 4-, and 5-year-old animals, respectively, were sexually mature. The size of the ovaries showed a marked increase in the 5-year age-class. The ovulation rate of ringed seals from Svalbard was calculated to be 0.91.

Purpose of the study. To establish the relationship between neurophysiological status and the level of efficiency in young people with bruxism.Materials and methods. Two groups of 64 and 53 subjects (males and females) aged 20–35 years old with bruxism and non-bruxers were formed according to questionnaire results and physical examination. The level of efficiency was assessed by the results of sensorimotor tracking of a moving object (the ‘Smile’ model). Spectral analysis was performed for evaluation of the baseline electroencephalograms. Microsoft Excel and Statistica 10.0 programs were used for statistical data processing.Results. The level of efficiency was statistically significantly lower in the hardest test of Smile model among the individuals with bruxism (p < 0.05). The bruxers also demonstrated a significantly lower dominant frequency and maximum amplitude of alpha-rhythm (p < 0.05), and significantly higher dominant frequency of beta2 rhythm (p < 0.05). The dominant frequency and the maximum amplitude of the alpha-rhythm are parameters corresponding to significant coefficients of the regression analysis. A negative relationship was found between the degree of error during sensorimotor tracking and the frequency and amplitude of alpha-rhythm.Conclusion. Regression models present the relationship between the level of efficiency and the alpha-rhythm severity. The regression equations make it possible to determine the functional state of the subject using an electroencephalogram.

AbstractBohn, H.: Revision of the panteli-group of Phyllodromica in Spain and Morocco (Blattaria: Blattellidae: Ectobiinae). Ent. scand. 24: 49-72. Copenhagen, Denmark. April 1993. ISSN 0013-8711. The species of the panteli-group are characterized by lobiform wings in both sexes and very specialized glands on tergite 7 in the males consisting of two pairs of long tubular pouches. The five or six species are distributed in southern Spain (P. panteli (Bolívar), P. coniformis sp. n., P. ignabolivari sp. n.) and northern Morocco (P. Janeri (Bolívar), P. vignai (Failla & Messina), P. sp. B). The distribution pattern suggests a colonization of Morocco from Spain across the Strait of Gibraltar. The characteristics of the panteli-group are reported, the relationship with other groups is discussed, all species are described and depicted, and keys for the identification of males and females are presented.

Development of self-efficacy scales allows the analysis of athletes’ perceptions and examination of the relationship between perception and performance. The aim of this paper was to: (1) develop a specific self-efficacy scale in a taekwondo task, the roundhouse kick, and (2) analyse the sport performance and its relationship with two self-efficacy scales (specific and general) outcomes according to the athletes’ gender.<strong> </strong>Forty-three taekwondo athletes (33 male and 10 female) participated in this study. The Physical (PSE) and Specific (RKSES) self-efficacy scales were administered. Performance data (impact force and total response time) were acquired by athletes kicking twice to an instrumented target. Results showed that the specific self-efficacy scale has high reliability and is able to predict sport performance in males and females. Males had higher self-efficacy scores and also higher performance results than females. Females’ taekwondo psychological training should be focus on improving their self-efficacy perception in order to increase their performance in the roundhouse kick. This specific self-efficacy scale for the taekwondo roundhouse kick offers empirical information to coaches, sport psychologists and researchers that allow them to predict athletes’ sport performance in the roundhouse kick.
