    Anger management in elementary school: descriptive exploration of a group intervention

    No full text
    Factors which may be critical to the success of children's anger management programs remain largely uninvestigated. Accordingly an exploratory study was undertaken to describe some of these factors, personal and situational, as observed during the implementation of a school program on anger management. Fifty-eight students (28 males and 30 females) in grades 5, 6, and 7 (ages 10.75 to 14.0 years) participated in a 6-lesson guidance unit on anger management. The unit consisted of a didactic component, covering cognitive-behavioural anger management techniques, and an art component, promoting exploration and expression of anger-related affect through painting. The two components occurred in a different sequence within the program for each half of the sample. Subjects provided data at the beginning, middle and end of the program on anger expression stylistics (Pediatric Anger Expression Scale), state and trait anger and anxiety (Pediatric Anger Scale and Pediatric Anxiety Scale), and knowledge of curriculum content (Anger Management Questionnaire). Subjects also completed the Children's Nowicki-Strickland Internal-External control scale. Independent raters assigned ratings for degree of anger and degree of defensiveness to each of the three paintings completed by each subject within the art component. Data analysis assessed the relationship between scores on the repeated measures and paintings and the following factors: the nature and sequence of program components and activities; and subject age, ability level, gender, and locus of control. In the second painting, subjects undergoing the art component first (art-first) expressed more anger (p < .05) than those doing the didactic component first (didactic-first), while on the third painting the latter were rated as more defensive (p < .01) than the former. The sample as a whole (p < .01) and both the art-first (p < .01) and didactic-first (p < .05) groups expressed more anger in the second painting than in either of the other two. Gender differences were found in state anger and knowledge of curriculum content at mid-program, and in degree of defensiveness on the first painting (all p < .05). External locus of control was associated at low levels with trait anxiety at mid-program and at the end, and with state anxiety at the end (all p < .05). Across the sample, trait anxiety was higher pre-program than at either the mid-point or the end (p < .05). State anger and state anxiety were substantially correlated (p < .01) on all three measurement occasions, although the range of the former measure was truncated due to floor effects. The results highlight the potential importance of the following factors: content and sequence of program components, nature of the relationship between instructor and students, and levels of state anger and state anxiety. Practical and research implications of the findings are discussed.Education, Faculty ofEducational and Counselling Psychology, and Special Education (ECPS), Department ofGraduat

    Some physico-chemical studies on two icosahedral viruses

    An investigation into the physical and chemical properties of two icosahedral viruses was undertaken, one a plant virus, carnation ringspot virus (CRSV), and the other an insect virus, Tipula iridescent virus (TIV). These viruses were studied using accepted chemical and biophysical methods and parameters such as amino acid composition, nucleotide composition, sedimentation coefficients, diffusion coefficients, molecular weights, hydration, and morphology in the electron microscope were determined. CRSV could be purified by frontal elution from AG1-X8 quaternary ammonium anion exchange resin with a NaCl-phosphate buffer, pH 6.8. The composition of CRSV based on nucleotides and amino acids recovered was 20.48% and 79.52% protein. Amino acid analyses indicated that the subunit protein was composed of approximately 347 amino acid residues with a subunit molecular weight of 38,000. The sedimentation and diffusion coefficients were 132 x 10¯¹³ sec and 1.48 x 10¯⁷ cm² /sec, respectively. A molecular weight based on the above two parameters was 7.07 x 10⁶. An uncorrected extinction coefficient at 260 mµ for the virus was found to be 6.46 cm² /mg virus. The frictional ratio calculated from the hypothetical diffusion coefficient of the anhydrous particle and the observed diffusion was 1.16. Assuming the virus particle to be spherical the degree of hydration was O.38 g water/g of virus. TIV was purified by sedimentation through a 5-40% sucrose density gradient. The particle molecular weight of TIV based on a sedimentation coefficient of 2200 x 10¯¹³ sec and a diffusion coefficient of 3.3 x 10¯⁸ cm²/sec was 5.51 x 10⁸ g/mole. A frictional ratio of 1.22 was calculated and the value of 0.57 g water/g virus was obtained assuming the deviation of the frictional ratio from unity was due to hydration. The DNA content based on total inorganic phosphorous liberated was 19 ± 0.2%. At 260 mμ the virus gave an uncorrected absorbance of 18.2 cm² /mg virus and a light scattering corrected absorbance of 9.8 cm² /mg virus. Amino acid analyses of the virus protein revealed a remarkable similarity to Sericesthis iridescent virus (SIV), suggesting a strain relationship. The relative amounts of all the amino acids of these two viruses, with the exception of arginine, are within experimental error. The possibility that the four iridescent insect viruses Sericesthis iridescent virus (SIV), mosquito iridescent virus (MIV), and Chilo iridescent virus (CIV) bear a strain relationship is discussed.Science, Faculty ofMicrobiology and Immunology, Department ofGraduat

    Ulichnye Familii among Doukhobors of the Caucasus and Canada

    No full text
    A longstanding folk tradition among rural Russian peasants, ulichnye familii (‘street surnames’) were used by Doukhobors colloquially ‘on the street’ of a village to distinguish among families sharing the same official surname. Similar to Quebecois dit names and Scottish sept names, ulichnye familii arose because of the low surname stock within Doukhobor society. Passed down to succeeding generations and transferred between settlements, these names became a recognized form of address among Doukhobors, helping structure kinship networks and organize social interactions among villagers. When a large contingent of Doukhobors emigrated from the Caucasus to the Canadian prairies in 1899, they continued this naming practice in their settlements well into the early 20th century. A ubiquitous part of their culture for generations, today ulichnye familii have all but disappeared among Doukhobors, as a result of their assimilation, dispersal and modernization. This article offers an analysis of the Doukhobor anthroponymic custom of ulichnye familii: the social factors leading to their adoption; the etymological processes through which these names were formed; the manner in which they were used and transmitted; and the elements contributing to their eventual decline and disuse. It also includes an inventory of extant ulichnye familii among the Doukhobors of the Caucasus and Canada, obtained through extensive field interviews and archival research
