Highly sensitive C-reactive protein and male gender are independently related to the severity of coronary disease in patients with metabolic syndrome and an acute coronary event

Patients with metabolic syndrome are at high-risk for development of atherosclerosis and cardiovascular events. The objective of this study was to examine the major determinants of coronary disease severity, including those coronary risk factors associated with metabolic syndrome, during the early period after an acute coronary episode. We tested the hypothesis that inflammatory markers, especially highly sensitive C-reactive protein (hsCRP), are related to coronary atherosclerosis, in addition to traditional coronary risk factors. Subjects of both genders aged 30 to 75 years (N = 116) were prospectively included if they had suffered a recent acute coronary syndrome (acute myocardial infarction or unstable angina pectoris requiring hospitalization) and if they had metabolic syndrome diagnosed according to the National Cholesterol Education Program/Adult Treatment Panel III. Patients were submitted to a coronary angiography and the burden of atherosclerosis was estimated by the Gensini score. The severity of coronary disease was correlated (Spearman’s or Pearson’s coefficient) with gender (r = 0.291, P = 0.008), age (r = 0.218, P = 0.048), hsCRP (r = 0.256, P = 0.020), ApoB/ApoA ratio (r = 0.233, P = 0.041), and carotid intima-media thickness (r = 0.236, P = 0.041). After multiple linear regression, only male gender (P = 0.046) and hsCRP (P = 0.012) remained independently associated with the Gensini score. In this high-risk population, male gender and high levels of hsCRP, two variables that can be easily obtained, were associated with more extensive coronary disease, identifying patients with the highest potential of developing new coronary events.

Spectral and symbolic analysis of the effect of gender and postural change on cardiac autonomic modulation in healthy elderly subjects

The objective of this study was to use linear and non-linear methods to investigate cardiac autonomic modulation in healthy elderly men and women in response to a postural change from the supine to the standing position. Fourteen men (66.1 ± 3.5 years) and 10 women (65.3 ± 3.3 years) were evaluated. Beat-to-beat heart rate was recorded in the supine and standing positions. Heart rate variability was studied by spectral analysis, including both low (LFnu-cardiac sympathetic modulation (CSM) indicator) and high (HFnu-cardiac vagal modulation (CVM) indicator) frequencies in normalized units as well as the low frequency/high frequency (LF/HF) ratio. Symbolic analysis was performed using the following indexes: 0V% (CSM indicator), 1V% (CSM and CVM indicators), 2LV% (predominantly CVM indicator) and 2ULV% (CVM indicator). Shannon entropy was also calculated. Men presented higher LFnu and LF/HF ratio and lower HFnu and 1V% symbolic index (57.56, 4.14, 40.53, 45.96, respectively) than women (24.60, 0.45, 72.47, 52.69, respectively) in the supine position. Shannon entropy was higher among men (3.53) than among women (3.33) in the standing position, and also increased according to postural change in men (3.25; 3.53). During postural change, the LFnu (24.60; 49.85) and LF/HF ratio (0.45; 1.72) increased, with a concomitant decrease in HFnu (72.47; 47.56) and 2LV% (14.10; 6.95) in women. Women presented increased CSM in response to postural change and had higher CVM and lower CSM than men in the supine position. In conclusion, women in the age range studied presented a more appropriate response to a postural change than men, suggesting that cardiac autonomic modulation may be better preserved in women than in men.

Gender differences in serum CK-MB mass levels in healthy Braziliansubjects

The creatine kinase-isoenzyme MB (CK-MB) mass assay is one of the laboratory tests used for the diagnosis of myocardial infarction. It is recommended, however, that reference limits should take gender and race into account. In the present study, we analyzed the plasma CK-MB mass and troponin levels of 244 healthy volunteers without a personal history of coronary artery disease and with no chronic diseases, muscular trauma or hypothyroidism, and not taking statins. The tests were performed with commercial kits, CK-MB mass turbo kit and Troponin I turbo kit, using the Immulite 1000 analyzer from Siemens Healthcare Diagnostic. The values were separated according to gender and showed significant differences by the Mann-Whitney test. Mean (± SD) CK-MB mass values were 2.55 ± 1.09 for women (N = 121; age = 41.20 ± 10.13 years) and 3.49 ± 1.41 ng/mL for men (N = 123; age = 38.16 ± 11.12 years). Gender-specific reference values at the 99th percentile level, according to the Medicalc statistical software, were 5.40 ng/mL for women and 7.13 ng/mL for men. The influence of race was not considered because of the high miscegenation of the Brazilian population. The CK-MB values obtained were higher than the 5.10 mg/mL proposed by the manufacturer of the laboratory kit. Therefore, decision limits should be related to population and gender in order to improve the specificity of this diagnostic tool, avoiding misclassification of patients

Effect of gender on training-induced vascular remodeling in SHR

There is accumulating evidence that physical inactivity, associated with the modern sedentary lifestyle, is a major determinant of hypertension. It represents the most important modifiable risk factor for cardiovascular diseases, which are the leading cause of morbidity and mortality for both men and women. In addition to involving sympathetic overactivity that alters hemodynamic parameters, hypertension is accompanied by several abnormalities in the skeletal muscle circulation including vessel rarefaction and increased arteriole wall-to-lumen ratio, which contribute to increased total peripheral resistance. Low-intensity aerobic training is a promising tool for the prevention, treatment and control of high blood pressure, but its efficacy may differ between men and women and between male and female animals. This review focuses on peripheral training-induced adaptations that contribute to a blood pressure-lowering effect, with special attention to differential responses in male and female spontaneously hypertensive rats (SHR). Heart, diaphragm and skeletal muscle arterioles (but not kidney arterioles) undergo eutrophic outward remodeling in trained male SHR, which contributed to a reduction of peripheral resistance and to a pressure fall. In contrast, trained female SHR showed no change in arteriole wall-to-lumen ratio and no pressure fall. On the other hand, training-induced adaptive changes in capillaries and venules (increased density) were similar in male and female SHR, supporting a similar hyperemic response to exercise.

Gender-dependent effects of aging on the kidney

It is well known that the kidney plays an important role in the development of cardiovascular diseases such as hypertension. The normal aging process leads to changes in kidney morphology, hemodynamics and function, which increase the incidence of cardiovascular events in the elderly population. These disturbances are influenced by several factors, including gender. In general, females are protected by the effects of estrogens on the cardiorenal system. Several studies have demonstrated the beneficial effects of estrogens on renal function in the elderly; however, the relationships between androgens and kidney health during one’s lifetime are not well understood. Sex steroids have many complex actions, and the decline in their levels during aging clearly influences kidney function, decreases the renal reserve and facilitates the development of cardiovascular disorders. Therefore, in this review, we discuss the cellular, biochemical, and molecular mechanisms by which sex hormones may influence renal function during the aging process.

Chronotype ontogeny related to gender

Chronotype is an established concept designed to identify distinct phase relationships between the expression of circadian rhythms and external synchronizers in humans. Although it has been widely accepted that chronotype is subjected to ontogenetic modulation, there is no consensus on the interaction between age and gender. This study aimed to determine the relationship between age- and gender-related changes in the morningness-eveningness character in a large sample of people. A total of 14,650 volunteers were asked to complete the Brazilian version of the Horne and Östberg chronotype questionnaire. The data demonstrated that, on average, women were more morning-oriented than men until the age of 30 and there were no significant differences between men and women from 30 to 45 years of age. In contrast to the situation observed until the age of 30, women older than 45 years were more evening-oriented than men. These results suggest that the ontogenetic development of the circadian timekeeping system is more plastic in men, as represented by the larger amplitude of chronotype changes throughout their aging process. The phase delay of adolescence and phase advance of the elderly seem to be phenomena that are more markedly present in men than in women. Thus, our data, for the first time, provide support that sharply opposes the view that there is a single path toward morningness as a function of age, regardless of gender.

Abundant immunohistochemical expression of dopamine D2 receptor and p53 protein in meningiomas: follow-up, relation to gender, age, tumor grade, and recurrence

Meningiomas are common, usually benign tumors, with a high postoperative recurrence rate. However, the genesis and development of these tumors remain controversial. We aimed to investigate the presence and implications of a mutated p53 protein and dopamine D2 receptor in a representative series of meningiomas and to correlate these findings with age, gender, tumor grade, and recurrence. Tumor tissue samples of 157 patients diagnosed with meningioma (37 males and 120 females, mean age 53.6±14.3 years) who underwent surgical resection between 2003 and 2012 at our institution were immunohistochemically evaluated for the presence of p53 protein and dopamine D2 receptor and were followed-up to analyze tumor recurrence or regrowth. Tumors were classified as grades I (n=141, 89.8%), II (n=13, 8.3%), or grade III (n=3, 1.9%). Dopamine D2 receptor and p53 protein expression were positive in 93.6% and 49.7% of the cases, respectively. Neither of the markers showed significant expression differences among different tumor grades or recurrence or regrowth statuses. Our findings highlight the potential role of p53 protein in meningioma development and/or progression. The high positivity of dopamine D2 receptor observed in this study warrants further investigation of the therapeutic potential of dopamine agonists in the evolution of meningiomas.

Gender, race and socioeconomic influence on diagnosis and treatment of thyroid disorders in the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil)

Thyroid diseases are common, and use of levothyroxine is increasing worldwide. We investigated the influence of gender, race and socioeconomic status on the diagnosis and treatment of thyroid disorders using data from the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil), a multicenter cohort study of civil servants (35-74 years of age) from six Brazilian cities. Diagnosis of thyroid dysfunction was by thyrotropin (TSH), and free thyroxine (FT4) if TSH was altered, and the use of specific medications. Multivariate logistic regression models were constructed using overt hyperthyroidism/hypothyroidism and levothyroxine use as dependent variables and sociodemographic characteristics as independent variables. The frequencies of overt hyper- and hypothyroidism were 0.7 and 7.4%, respectively. Using whites as the reference ethnicity, brown, and black race were protective for overt hypothyroidism (OR=0.76, 95%CI=0.64-0.89, and OR=0.53, 95%CI=0.43-0.67, respectively, and black race was associated with overt hyperthyroidism (OR=1.82, 95%CI=1.06-3.11). Frequency of hypothyroidism treatment was higher in women, browns, highly educated participants and those with high net family incomes. After multivariate adjustment, levothyroxine use was associated with female gender (OR=6.06, 95%CI=3.19-11.49) and high net family income (OR=3.23, 95%CI=1.02-10.23). Frequency of hyperthyroidism treatment was higher in older than in younger individuals. Sociodemographic factors strongly influenced the diagnosis and treatment of thyroid disorders, including the use of levothyroxine.

Gender-toiminta osana sotilaallista kriisinhallintaa : rekrytointi, koulutus ja operatiivinen toiminta

Kansainväliset sotilaalliset kriisinhallintaoperaatiot ovat muuttuneet yhä vaativammiksi, ja kriisinhallinnan tehtäväkenttä on laajentunut ja monipuolistunut. Operaatioalueella olevilta kriisinhallintahenkilöiltä odotetaan yhä enemmän kykyä yhteistyöhön kaikkien toimijoiden kanssa yhteiskunnan vakauden ja turvallisuuden palauttamiseksi ja säilyttämiseksi. Yhdistyneiden kansakuntien päätöslauselman 1325 ”Naiset, rauha ja turvallisuus” täytäntöönpanolla halutaankin hyödyttää koko yhteiskunnan vakautta ja kehitystä. Suomen kansallisen toimintaohjelman ja Pääesikunnan normin mukaan Suomi tukee naisten kouluttautumista kohti vaativimpia tehtäviä ja esittää naisia kansainvälisiin johtotehtäviin. Suomi varmistaa, että kaikilla kriisinhallintatehtäviin lähtevillä on ihmisoikeus- ja tasa-arvokysymysten asiantuntemus sekä kyky tehdä yhteistyötä sisällyttämällä YK:n päätöslauselma 1325, kansainvälinen oikeus, kansainvälinen humanitaarinen oikeus sekä ihmisoikeusvelvoitteet kaikkeen kriisinhallintakoulutukseen. Suomi sisällyttää gender-näkökulman osak-si kriisinhallintajoukkojen operatiivista toimintaa huomioimalla gender-näkökulman operaatioiden suunnittelussa, toimeenpanossa ja raportoinnissa YK:n päätöslauselman 1325 ja operaatiokohtaisten määräysten mukaisesti. Tutkielman tarkoituksena oli tutkia puolustusvoimien virassa olevien naisupseerien motiiveja hakeutua kriisinhallintatehtäviin, naisten osallistumisen vaikutuksia kriisinhallintaoperaatioihin sekä gender-näkökulman huomioimista koulutuksessa ja kriisinhallintajoukon operatiivisessa toiminnassa. Tutkimusongelmana oli vähäinen aiempi tiedon määrä Suomen kansallisessa toimintaohjelmassa ja Pääesikunnassa määritetyn gender-toiminnan toteutumisesta. Päätutkimuskysymyksen avulla pyrittiinkin selvittämään, miten gender-toiminta on toteutu-nut sotilaallisen kriisinhallinnan rekrytoinnissa, koulutuksessa ja operatiivisessa toiminnassa. Tutkimusstrategiana sovellettiin monimenetelmäistä tiedonkeruutapaa määrällisen ja laadullisen aineiston saamiseksi. Tutkimusmenetelminä käytettiin survey-tutkimusta ja sisällönanalyysiä, joiden avulla pyrittiin kuvaamaan naisupseerien, operaatioista kotiutuneiden rauhanturvaajien sekä Afganistanin kriisinhallintaoperaatiossa (ISAF) palvelleiden SKJA:n komentajien ja naisupseerien käsityksiä, mielipiteitä ja asenteita tutkittavasta aiheesta. Tutkielman empiirinen osuus perustuu naisupseereille suunnattuun kyselyyn sekä SKJA:n komentajien ja naisupseerien sähköpostihaastatteluun. Tutkielmassa hyödynnettiin lisäksi Porin prikaatin kotiutuneille rauhanturvaajille teettämän tasa-arvokyselyn tuloksia. Tutkielman tuloksena ilmeni, että naisrauhanturvaajien kriisinhallintatehtäviin osallistumisen vaikutuksista merkittävimpiä olivat yhteyden saaminen paikalliseen naisväestöön. Myös miesten ja naisten työskentely yhdessä samoissa tehtävissä nähtiin tärkeänä esimerkkinä sukupuolten tasa-arvosta. Sukupuolen liiallinen korostaminen nähtiin haitalliseksi, ja tehtävän vaatimukset tuleekin asettaa tehtävässä tarvittavien ominaisuuksien, tietojen ja taitojen mukaisesti. Positiivisten vaikutusten saavuttamiseksi naisten määrän kriisinhallintatehtävissä tulisi kasvaa nykyisestä, mutta sen ei tule olla itseisarvo. Merkittävimmät naisupseerien kriisinhallintatehtäviin hakeutumattomuuden syyt olivat perheen perustamiseen liittyvät sosiaaliset syyt. Kriisinhallintatehtäviin hakeutumisen motivaatiota kasvattavista tekijöistä tärkeimpiä olivat ammattitaidon ja itsensä kehittäminen. Gender-koulutuksen osalta ilmeni, että Suomessa annetaan gender-peruskoulutus mutta operaatioalueella ei täydennyskoulutusta annettu. Gender-näkökulman huomioon ottaminen kriisinhallintajoukon operatiivisessa suunnittelussa, toimeenpanossa ja raportoinnissa ei myöskään tulosten perusteella toteutunut. Tutkielman johtopäätöksenä todetaan, että naisupseerit ovat pääosin halukkaita palvelemaan kriisinhallintatehtävissä, vaikka osallistuminen onkin henkilömäärältään vähäistä. Naisten mahdollisuuteen hakeutua kriisinhallintatehtäviin voidaan vaikuttaa laatimalla urasuunnitelma varhaisemmassa vaiheessa ja lisäämällä naisupseereille kohdennettua tietoa kriisinhallintatehtävistä. Kriisinhallintatehtäviin halukkaita naisia on enemmän kuin näyttäisi olevan mahdollista irrottaa kotimaan tehtävistä. Gender-koulutuksen todettiin olevan liian yleisellä tasolla eikä sitä kyetty konkreettisesti huomioimaan ja soveltamaan joukon operatiivisessa toiminnassa. Koulutuksen pääpainon tulisikin olla operatiivisessa vaikuttavuudessa osana kaikkea koulutusta. Gender-näkökulma tulisi saada integroitua osaksi kaikkea kriisinhallintajoukon toimintaa operaation vaikuttavuuden ja tavoitteiden täyttymisen näkökulmaa. Operaation tavoitteita asetettaessa tulisi muistaa, että kriisinhallintaoperaatioilla pyritään kokonaisvaltaisesti turvallisuusympäristön parantamiseen ja normaaliyhteiskunnan toimintojen ja palvelujen palauttamiseen. Gender-toiminnan kehittämisessä tärkeää onkin ymmärtää sen vaikutus ja kytkeminen nimenomaan paikallisväestön eri ihmisryhmien huomioimiseen ja tasavertaisuuteen ihmisoikeuksien näkökulmasta. Tutkielman tulosten mukaan kehityskohteita gender-toiminnan parantamiseksi on olemassa, ja mikäli kriisinhallintaoperaatioiden vaikuttavuutta halutaan tehostaa, näyttäisi siihen myös olevan keinoja.

Quest/ion of Identities in African American Feminist Postmodern Drama: A Study of Selected Plays by Suzan-Lori Parks

Innovative and unconventional, Pulitzer Prize-winning playwright Suzan-Lori Parks belongs to the continuum of African American playwrights who have contributed to the quest/ion – the quest for and question – of identities for African Americans. Her plays are sites in which the quest/ion of identities for African Americans is pursued, raised and enacted. She makes use of both page and stage to emphasize the exigency of reshaping African Americans’ identities through questioning the dominant ideologies and metanarratives, delegitimizing some of the prevailing stereotypes imposed on them, drawing out the complicity of the media in perpetuating racism, evoking slavery, lynching and their aftereffects, rehistoricizing African American history, catalyzing reflections on the various intersections of sex, race, class and gender orientations, and proffering alternative perspectives to help readers think more critically about issues facing African Americans. In my dissertation, I approach three plays by Parks – The Death of the Last Black Man in the Whole Entire World (1990), Venus (1996) and Fucking A (2000) – from the standpoints of postmodern drama and African American feminism with a focus on the terrains that reflect the quest/ion of identities for African Americans, especially African American women. I argue that postmodern drama and African American feminism provide the ground for Parks to promote the development of a political agenda in order to call into question a number of dominant ideologies and metanarratives with regard to African Americans and draw upon the roles of those metanarratives as a powerful apparatus of racial and sexual oppressions. I also explore how Parks engages with postmodern drama and African American feminism to incorporate her own mininarratives in the dominant discourses. I argue that Parks in these plays uses postmodern drama and African American feminism to encourage reflections on intersectionality in order to reveal the concerns of African Americans, particularly African American women. Her plays challenge the dominant order of hierarchy and patriarchy, while in some cases urging unity and solidarity between African American men and women by showing how unity and solidarity can help them confront race, class and gender oppressions. Furthermore, I discuss how the utilization of postmodern techniques and devices helps Parks to transform the conventional features of playwriting, to create incredulity toward the dominant systems of oppression and to incorporate her mininarratives within the context of dominant discourses.

Gender and human security : the challenge facing Canada's human security policy /

During the 1980's and for much of the 1990's, many countries in the Asia Pacific were renowned for their economic development and prosperity. The Asian tigers were a source of great interest for many economists and international investors. The 1997 Asian financial crisis, however, dramatically altered the growth and the performance of these economies. The crisis sent several ofAsia's best performing economies on a downward spiral from which many have yet to fully recover. The crisis exposed the financial and the political weaknesses ofmany countries in the region. Moreover, the crisis severely affected the wellbeing and the security ofmany ofthe region's citizens. This text will examine the economic crisis in greater detail and explore current debates in the study of international relations theory. More specifically, this paper will examine recent challenges posed to traditional international relations theory and address alternative approaches to this field of study. This paper will examine Critical theory and its role in shifting the referent object of security from the state to the individual. In this context, this paper will also assess Critical theory's role in enabling such issues as gender and human security to find a place on the agendas of international relations scholars and foreign policy makers. The central focus ofthis study will be the financial crisis and its impact on human security in the Southeast Asia. Furthermore, this paper will assess the recovery efforts ofthe domestic governments, international organizations and various Canadian sponsored initiatives in the context ofhuman security.

The influence of physical attractiveness and gender on perceived competence of sportscasters

The media tends to represent female athletes as women first and athletes second (Koivula, 1 999). The present study investigated whether this same trend was present for female sportscasters, using a self-presentational framework. Self-presentation is the process by which people try to control how others see them (Leary, 1995). One factor that may influence the type of image they try to project is their roles held in society, including gender roles. The gender roles for a man include dominance, assertiveness, and masculinity, while the gender roles for a woman include nurturer, femininity, and attractiveness (Deaux & Major, 1 987). By contrast, sports broadcasters are expected to be knowledgeable, assertive, and competent. Research suggests that female sports broadcasters are seen as less competent and less persuasive than male sports broadcasters (Mitrook & Dorr, 2001; Ordman & Zillmann, 1994, Toro, 2005). One reason for this difference may be that the gender roles for a man are much more similar to those of a sportscaster, compared to those of a woman. Thus, there may be a conflict between the two roles for women. The present study investigated whether the gender and perceived attractiveness of sportscasters influenced the audience's perceptions of the level of competence that a sportscaster demonstrates. Two hundred and four male (n =75) and female (n =129) undergraduate students were recruited from a southern Ontario university to participate in the study. The average age of the male participants was 21 .23 years {SD =1 .60), and the average age for female participants was 20.67 years {SD = 1 .31). The age range for all participants was from 19 to 30 years {M = 20.87 years, SD = 1 .45). Af^er providing informed consent, participants randomly received one of four possible questionnaire packages. The participants answered the demographic questionnaire, and then proceeded to view the picture and read the script of a sports newscast. Next, based on the picture and script, the participants answered the competence questionnaire, assessing the general, sport specific, and overall competence of the sportscaster. Once participants had finished, they returned the package to the researcher and were thanked for their time. Data was analyzed using an ANOVA to determine if general sport competence differs with respect to gender and attractiveness of the sportscaster. Overall, the ANOVA was non-significant (p > .05), indicating no differences on the dependent variable based on gender (F (3, 194) = .631, p = .426), attractiveness (F (3, 194) = .070, p = .791), or the interaction of the two {F (3, 194) = .043,/? = .836). Although none of the study hypotheses were supported, the study provided some insight to the perceived competence of female sportscasters. It is possible that female sportscasters are now seen as competent in the area of sports. Sample characteristics could also have influenced these results; the participants in the current study were primarily physical education and kinesiology students, who had experience participating in physical activity with both men and women. Future research should investigate this issue further by using a video sportscast. It is possible that delivery characteristics such as voice quality or eye contact may also impact perceptions of sportscasters.

The exercise leader's gender and physique salience : effects on self-presentational concerns in an exercise context

Self-presentation is the process by which individuals attempt to monitor and control how others perceive and evaluate them (Leary, 1992; Leary & Kowalski, 1990). Self-presentational concerns have been shown to influence a number of exercise-related behaviours, cognitions, and affective responses to exercise (e.g., social anxiety). Social anxiety occurs when an individual wants to create a specific impression on others, but is unsure (s)he will be successful (Leary & Kowalski, 1995). Social physique anxiety (SPA) is a specific form of social anxiety related the evaluation of one's body (Hart, Leary, & Rejeski, 1989). Both social anxiety and SPA may act as deterrents to exercise (Lantz, Hardy, & Ainsworth, 1997; Leary, 1992), so it is important to examine factors that may influence social anxiety and SPA; one such factor is self-presentational efficacy (SPE). SPE is one's confidence in successfully making desired impressions on others (Leary & Atherton, 1986) and has been associated with social anxiety and SPA (Leary & Kowalski, 1995; Gammage, Martin Ginis, & Hall, 2004). Several aspects of the exercise environment, such as the presence of mirrors, clothing, and the exercise leader or other participant characteristics, may be manipulated to influence self-presentational concerns (e.g., Gammage, Martin Ginis et aI., 2004; Martin & Fox, 2001; Martin Ginis, Prapavessis, & Haase, 2005). Given that the exercise leader has been recognized as one of the most important influences in the group exercise context (Franklin, 1988), it is important to further examine how the leader may impact self-presentational concerns. The present study examined the impact of the exercise leader's gender and physique salience (i.e., the extent to which the body was emphasized) on SPE, state social anxiety (SSA), and state social physique anxiety (SPA-S) of women in a live exercise class. Eighty-seven college-aged female non- or infrequent exercisers (i.e., exercised 2 or fewer times per week) participated in a group exercise class led by one of four leaders: a female whose physique was salient; a female whose physique was non-salient; a male whose physique was salient; or a male whose physique was non-salient. Participants completed measures of SPE, SSA, and SPA-S prior to and following completion of a 30- minute group exercise class. In addition, a measure of social comparison to the exercise leader and other participants with respect to attractiveness, skill, and fitness was completed by participants following the exercise class. A MANOV A was conducted to examine differences between groups on postexercise variables. Results indicated that there were no significant differences between groups on measures ofSPE, SSA, or SPA-S (allp's > .05). However, when all participants were collapsed into one group, a MANOV A showed a significant time effect (F(3, 81) = 19.45,p < .05, 1')2= .419). Follow-up ANOVAs indicated that post-exercise SPE increased significantly, while SSA and SPA-S decreased significantly (SPE: F(I, 83) = 30.87,p < .001,1')2 = .27; SSA: F(I,83) = 11.09,p < .001, 1')2 = .12; SPA-S: F (1,83) = 42.79,p < .001, 1')2 = .34). Further, results of a MANOVA revealed that participants who believed they were less fit than other group members (i.e., made negative social comparisons) reported significantly more post-exercise SSA and SP A-S than those who believed they were more fit than the other participants (i.e., made positive comparisons; SSA: F(2, 84) = 3.46, p < .05, 1')2 = .08; SPA-S: F(2, 84) = 5.69, p < .05, 1')2 = .12). These results may indicate that successfully completing an exercise class may serve as a source of SPE and lead to reduced social anxiety and SPA-S in this population. Alternatively, characteristics of the exercise leader may be less important than characteristics of the other participants. These results also suggest that the types of social comparisons made may influence self-presentational concerns in this sample. Future research should examine how the type of social comparison (i.e., negative or positive) made to the other group members may either generate or reduce anxiety. Also, factors that contribute to the types of social comparisons made with other exercisers should be examined. Implications for practice and research are discussed.

Citizen Jane : exploring the relationship between gender and cellular phones in societies of control

In this thesis, I argue that the mutually productive relationship between women (as gendered subjects) and cellular phone technology is one of control. Women use cellular phones to organize, manage and otherwise control the multiplicity of tasks required of them on a daily basis. At the same time, through using cell phones, women participate in regimes of control including surveillance and persistent connection. I explore this relationship at the level of everyday practice, and conclude by speculating about this relationship at a wider level of social control and organization. This argument emerges from the critical approach suggested by Slack and Wise (2005), who argue that technology and culture are inseparable. They provide articulations and assemblages as tools of analysis. I situate this analysis more broadly within Foucault's (1991) work on govemmentality, in its modem form of societies of control (Deleuze, 1995b).
