The Acute Effects of Aerobic and Resistance Exercise on Cardiovascular Function and Arterial Stiffness
The cardiovascular system changes acutely to the stresses of exercise to support the increased metabolic demand of the working tissues. This is accomplished through the augmentation of several parameters including heart rate, blood pressure, and vascular tone such as arterial stiffness. Exercise training has been shown to elicit changes in arterial stiffness but the acute effects of exercise on arterial stiffness have not been thoroughly studied. The current study examined the acute effects of no (control), aerobic (30 minutes of cycling at ~70% maximum heart rate), and resistance exercise (30 minutes, 3 sets of 10 repetitions for 6 exercises) on arterial stiffness in healthy males (n=11) utilizing measures of carotid-femoral pulse wave velocity and pulse wave analysis at rest and during recovery for 60 minutes. The exercise sessions utilized were consistent with American College of Sports Medicine guidelines for exercise in healthy individuals. Carotid-femoral pulse wave velocity demonstrated no significant change from resting values throughout recovery for any of the activities (~9 m·s-1). Systemic arterial stiffness values (corrected to a heart rate of 75 bpm) were significantly higher post-resistance exercise than the control and aerobic exercise activities initially (34.2 ± 10.3% vs. 14.2 ± 10.9% and 3.2 ± 12.7%, p\u3c0.05) and remained statistically higher throughout recovery. These results indicate that resistance exercise alone resulted in an increase in systemic arterial stiffness that lasted for at least 60 minutes. In contrast, neither aerobic or resistance activity elicited a change in regional arterial stiffness. Further studies may clarify the time course and mechanisms for changes in arterial stiffness following acute and chronic exercise of various modalities and intensities
A Mobile Game to Support Smoking Cessation: Prototype Assessment
Background: Cigarette smoking results in an estimated seven million deaths annually. Almost half of all smokers attempt to quit each year, yet only approximately 6% are successful. Although there are multiple effective interventions that can increase these odds, substantial room remains for improvement. One effective approach to helping smokers quit is contingency management, where quitting is incentivized with the delivery of monetary rewards in exchange for objective evidence (e.g., exhaled carbon monoxide levels) of abstinence.
Objective: We assessed the feasibility and promise of Inspired, a contingency management mobile app for smoking cessation that uses game-based rewards to incentivize abstinence from smoking instead of the monetary (or material) rewards typically used. We sought participant feedback and limited objective data on: the features and design of Inspired, interest in using Inspired when it becomes available, the likelihood of Inspired being an effective cessation aid, and the rank order preference of Inspired relative to other familiar smoking cessation aids.
Methods: Twenty-eight treatment-seeking smokers participated in this study. Participants attended a single one-hour session in which they received an overview of the goals of the Inspired mobile game, practiced submitting breath carbon monoxide (CO) samples, and played representative levels of the game. Participants were then told that they could play an extra level, or they could stop, complete an outcome survey, receive payment, and be dismissed. A sign-up sheet requesting personal contact information was available for those who wished to be notified when the full version of Inspired becomes available.
Results: Using binary criteria for endorsement, participants indicated that, assuming it was currently available and fully developed, they would be more likely to use Inspired than: any other smoking cessation aid (21/28, 75%), the nicotine patch (23/28, 82%), a drug designed to reduce smoking cravings (23/28, 82%), or a program involving attendance in training sessions or support group meetings (27/28, 96%). In the questionnaire, participants indicated that both the Inspired program (26/28, 93%) and the Inspired game would be “Fun” (28/28, 100%), and 71% (20/28) reported that the program would help them personally quit smoking. Fifty-eight percent of participants (15/26) chose to continue playing the game rather than immediately collecting payment for participation and leaving. Eighty-two percent of participants (23/28) signed up to be notified when the full version of Inspired becomes available.
Conclusions: This was the first study to evaluate a game-based contingency management app that uses game-based virtual goods as rewards for smoking abstinence. The outcomes suggest that the completed app has potential to be an effective smoking cessation aid that would be widely adopted by smokers wishing to quit
Relationship Between Food Craving And Food Selection
Objective: The primary aim of this study was to determine the influence of craving on food selection.
Research Methods and Procedures: A total of 95 viable participants completed the food craving inventory
(FCI), a restaurant meal selection questionnaire, and various demographic questions. Linear regression
modeling was used to analyze the relationship between FCI craving score and various forms of caloric intake.
Logistic regression models were utilized to analyze the relationship between “high-craving” status and food
selection.
Results: No significant findings resulted from modelling the relationship between craving category FCI scores
and craved caloric intake using Pearson’s coefficient. Likewise, no significant relationships were observed
between craving category FCI scores and total caloric intake. Various significant relationships resulted from
modelling the relationship between “high-craver” status and food selection. “High-craver” status for CARB
and SWEET were significant predictors of choosing a high-fat meal. “High-craver” status for FFF was found
to be a significant predictor of choosing a high-FFF meal. “High-craver” status for FFF and SWEET were
significant predictors for choosing a high-carb meal.
Discussion: While no significant associations were observed using linear regression to model the relationship
between FCI score and caloric intake, these insignificant relationships may not hold true when more robust
dietary measures for food selection are utilized and a larger sample size is polled. A number of significant
relationships were elucidated using logistic regression to assess the relationship between “high-craver” status
and food selection. Some of these relationships were positive and others inverse; however, important ideas
concerning craving and food choice can be garnered from each of these.
Conclusion: There are a number of limitations associated with this study; however, despite these limitations,
this study provides an important base for the relationship between the magnitude of an individual’s craving
score and food selection. With more robust studies centering around the same topic matter, it is possible that
more concrete relationships between craving and food selection can be illuminated
Credit, equity, and mortgage refinancings
Using a unique loan level data set that links individual household credit ratings with property and loan characteristics, the authors test the extent to which homeowners' credit ratings and equity affect the likelihood that mortgage loans will be refinanced as interest rates fall. Their logit model estimates strongly support the importance of both the credit and equity variables. Furthermore, the authors' results suggest that a change in the overall lending environment over the past decade has increased the probability that a homeowner will refinance.Mortgages
Refletindo sobre o "normal", o "diferente", e o "ex-cêntrico"
O presente artigo tenciona analisar as fragmentações pelas quais a sociedade pós-moderna e, especificamente, o individuo passa nesses últimos 30 anos. Analisaremos a identidade Pós-moderna como algo que já não cabe certezas ou centros de segurança. Isso implica uma ruptura definitiva com a possibilidade de uma identidade essencial, coesa, fixa, imaculada, permanente. É a partir da Identidade Pós-moderna que iremos nos objetivar sobre a questão do indivíduo, que tem sido estudada em vários campos do conhecimento, como conseqüência das mudanças ocorridas no cerne das formações culturais da modernidade. Com a emergência das sociedades pós-modernas, desintegram-se, por um lado, os sistemas filosóficos tradicionais e essencialistas e perde-se, por outro, o sentido de continuidade entre passado, presente e futuro.O sujeito começa a experimentar a angústia existencial e viver uma profunda crise de identidade. Portanto, a crise do indivíduo pós-moderno reflete as mudanças que deslocaram as estruturas e processos centrais das sociedades pós-modernas, “abalando os quadros de referência que davam aos indivíduos uma ancoragem estável ao mundo social” (Hall, 1999, p.9).
Identifying Video Game Preferences Among Adults Interested in Quitting Smoking Cigarettes: Survey Study.
BACKGROUND: Smoking is the most prevalent cause of morbidity and mortality in the United States. Although most individuals who smoke express a desire to quit smoking, only a small percentage are successful. Serious games have become popular in health sectors as a potential avenue for delivering a scalable treatment that is both accessible and engaging for the smoking population. Several smoking cessation games have already been developed, but these games feature a broad range of gameplay elements and are not necessarily based on existing video game preferences in the general or smoking population.
OBJECTIVE: To better inform treatment development, this study aims to evaluate video game genre preferences among treatment-seeking individuals who smoke (N=473).
METHODS: Participants responded to a screening survey to enroll in a larger, serious game intervention for smoking cessation. During this screening survey, participants were asked to disclose their favorite video games, which resulted in 277 unique game titles. These titles were coded for genre categories based on publisher listings and game features. The genres were then analyzed for the frequency of reporting overall and across age groups.
RESULTS: Action, Role-Playing, and Action-Adventure were the most reported genres among adults aged ≤34 years; Action, Action-Adventure, and Logic were the most reported genres among adults aged 35-44 years; and Logic and Action were the most reported genres among adults aged ≥45 years.
CONCLUSIONS: These data indicate that treatment-seeking individuals who smoke have different game preferences across age groups, and the data provide novel information to inform the development of future serious games targeting the smoking population that are tailored to the preferences of their age group.

The Influence of Perceived Career Barriers on College Women's Career Planning
Research has indicated that balancing work and family is on the minds of college-age women long before they are married. At the same time, women continue to choose occupations that do not fully utilize their abilities and often fail to follow their original career goals. The purpose of this study was to examine the influence of perceived career barriers and supports on young women's career planning. Utilizing Social Cognitive Career Theory (SCCT) and recent literature as a basis, this study conceptualized career goals using the two constructs career salience and career aspirations. Based on information garnered in this student's thesis and on studies examining pathways in the SCCT model, the current study used a hierarchical regression model and hypothesized that barriers related to work and family conflict and sex discrimination would have the most impact on the career aspirations and career salience of young women. Career supports were hypothesized to add significantly to the prediction of these variables, and coping self-efficacy for these types of barriers were hypothesized to depend on the level of these types of barriers perceived and the interaction effect was in turn expected to add significantly to the prediction of career aspirations and career salience. None of the hypotheses were supported in predicting career salience. Career aspirations were found to be predicted by barriers other than those hypothesized, career supports were found to add significant variance, and coping self-efficacy for work and family conflict was found to have a unique, unpredicted relationship with career aspirations. Implications of the findings are discussed as are suggestions for directions of new research utilizing SCCT
