dissertationThis study examined preadolescents' and adolescents' narratives about their interpersonal conflicts with parents and friends as a window into the processes of the youths' individuation and connectedness in these close relationships. One hundred eight participants, 18 males and 18 females in each of three age groups (ages 10, 14, and 17), provided three narrative accounts relating to a time when they disagreed with their mother, their father, and their best friend. It was found that the youths' conceptions of their individuation and connectedness increased in complexity with age. Relationship context; differences were also found for both individuation and connectedness: Allusions to individuated desires were more common in the child-parent than the friendship narratives, and allusions to connectedness were more common in the friendship than in the child-parent narratives. Additionally, girls referred to disturbances in their connectedness to others more frequently than boys. The findings contribute to our understanding of the facilitative role of conflicts for individuation and connectedness processes across development as well as the ways in which different relationships provide somewhat different, but to an extent overlapping, context;s for these developmental processes

Cyclic nucleotides in tissues during long-term hypokinesia

Male Wistar rates were kept hypokinetic by placing them in small containers for 22 days. Blood plasma cAMP content was subsequently found increased, and cGMP content decreased, in the experimental animals. Liver and thymus cAMP content was similar in the control and experimental animals. There was a 20 and 38% decrease of cAMP content in the kidneys and spleen, respectively. Hypokinesia's reduction of cyclic nucleotides seems to inhibit RNA and protein synthesis

An Examination of the Association of Selected Toxic Metals with Total and Central Obesity Indices: NHANES 99-02

It is conceivable that toxic metals contribute to obesity by influencing various aspects of metabolism, such as by substituting for essential micronutrients and vital metals, or by inducing oxidative stress. Deficiency of the essential metal zinc decreases adiposity in humans and rodent models, whereas deficiencies of chromium, copper, iron, and magnesium increases adiposity. This study utilized the NHANES 99-02 data to explore the association between waist circumference and body mass index with the body burdens of selected toxic metals (barium, cadmium, cobalt, cesium, molybdenum, lead, antimony, thallium, and tungsten). Some of the associations were significant direct relationships (barium and thallium), and some of the associations were significant inverse relationships (cadmium, cobalt, cesium, and lead). Molybdenum, antimony, and tungsten had mostly insignificant associations with waist circumference and body mass index. This is novel result for most of the toxic metals studied, and a surprising result for lead because high stored lead levels have been shown to correlate with higher rates of diabetes, and obesity may be a key risk factor for developing diabetes. These associations suggest the possibility that environmental exposure to metals may contribute to variations in human weight gain/loss. Future research, such as prospective studies rather than the cross-sectional studies presented here, is warranted to confirm these findings

Maternal blood cadmium, lead and arsenic levels, nutrient combinations, and offspring birthweight

Abstract Background Cadmium (Cd), lead (Pb) and arsenic (As) are common environmental contaminants that have been associated with lower birthweight. Although some essential metals may mitigate exposure, data are inconsistent. This study sought to evaluate the relationship between toxic metals, nutrient combinations and birthweight among 275 mother-child pairs. Methods Non-essential metals, Cd, Pb, As, and essential metals, iron (Fe), zinc (Zn), selenium (Se), copper (Cu), calcium (Ca), magnesium (Mg), and manganese (Mn) were measured in maternal whole blood obtained during the first trimester using inductively coupled plasma mass spectrometry. Folate concentrations were measured by microbial assay. Birthweight was obtained from medical records. We used quantile regression to evaluate the association between toxic metals and nutrients due to their underlying wedge-shaped relationship. Ordinary linear regression was used to evaluate associations between birth weight and toxic metals. Results After multivariate adjustment, the negative association between Pb or Cd and a combination of Fe, Se, Ca and folate was robust, persistent and dose-dependent (p < 0.05). However, a combination of Zn, Cu, Mn and Mg was positively associated with Pb and Cd levels. While prenatal blood Cd and Pb were also associated with lower birthweight. Fe, Se, Ca and folate did not modify these associations. Conclusion Small sample size and cross-sectional design notwithstanding, the robust and persistent negative associations between some, but not all, nutrient combinations with these ubiquitous environmental contaminants suggest that only some recommended nutrient combinations may mitigate toxic metal exposure in chronically exposed populations. Larger longitudinal studies are required to confirm these findings

Darba autore salīdzina romānu varoņus un uz salīdzināmas analīzes pamata noskaidro kopīgas un atšķirīgas šo personāžu iezīmes. Darbs sastāv no divām nodaļām: pirmajā nodaļā tiek apkopoti, analizēti, sistematizēti un izskatīti romāniem un to varoņiem veltīti darbi. Otrajā nodaļā varoņu tēli tiek atklāti salīdzināmi sastatāmajā aspektā. Viņā realizēsies liktie mērķi un uzdevumi. Šis pētījums var ieinteresēt speciālistus: bibliogrāfus, mākslas zinātniekus, literatūras zinātniekus un rakstniekus.The research is devoted to the comparative analysis of the literary images of Voland and Ostap Bender in M. Bulgakov's 'The Master and Margarita' and I. Ilf and E. Petrov's 'The Twelve Chairs' and 'The Little Golden Calf'. The aim of the research is to compare both characters and to elicit differences and similarities of their literary images. The paper consists of two chapters. The first chapter summarizes, systematizes and reviews previous research on the novels and their characters. The aims and goal of the research are achieved in the second chapter, which provides comparative analysis of both characters. Present research can be used by bibliographers, art critics, literary critics and writers

IKT izmantošanas iespējas mācību procesā un jaunais mācību saturs. Trešā daļa ir par pedagogu pieredzi darbā ar IKT pētījumu skolā “X”, tur ir apkopoti anketēšanas (pedagogiem un direktora vietniekam IT jomā) rezultāti. Darba autore: Daila Komolova Darba vadītājs: Ivars Muzis Darba nosaukums: Pedagoga profesionālās kompetences pilnveide IKT izmantošanā pedagoģiskā darbā vispārizglītojošā skolā Darba mērķis: saprast jaunā mācību satura būtību, lai pilnveidotu savas pedagoģiskās kompetences Darba pētījuma saturs un rezultāti: sastāv no anketēšanas. Anketas bija izveidotas skolotājiem un direktora vietniekam IT jomā, lai izpētītu IKT lietošanu stundas laikā digitālās kompetences pilnveidei, lai pilnveidotu visas parējās kompetences. Skolotāji izmanto tehnoloģijas gandrīz katru stundu, tomēr to izmantošana nav daudzpusīga, tas nozīmē, ka digitālā kompetence pilnveidojas, bet ne tik strauji cik vēlams.
