Brain tumor detection using fusion of hand crafted and deep learning features

The perilous disease in the worldwide now a days is brain tumor. Tumor affects the brain by damaging healthy tissues or intensifying intra cranial pressure. Hence, rapid growth in tumor cells may lead to death. Therefore, early brain tumor diagnosis is a more momentous task that can save patient from adverse effects. In the proposed work, the Grab cut method is applied for accurate segmentation of actual lesion symptoms while Transfer learning model visual geometry group (VGG-19) is fine-tuned to acquire the features which are then concatenated with hand crafted (shape and texture) features through serial based method. These features are optimized through entropy for accurate and fast classification and fused vector is supplied to classifiers. The presented model is tested on top medical image computing and computer-assisted intervention (MICCAI) challenge databases including multimodal brain tumor segmentation (BRATS) 2015, 2016, and 2017 respectively. The testing results with dice similarity coefficient (DSC) achieve 0.99 on BRATS 2015, 1.00 on BRATS 2015 and 0.99 on BRATS 2017 respectively.     

How Do Religion and Sexual Orientation Affect Support for U.S. Presidential Candidates? Evidence from a Survey Experiment

A growing body of research has examined how candidates’ religion or sexual orientation affect voting likelihood among the U.S. public. No systematic study, however, has focused on the combined effect of these traits. We draw on the intersectionality literature to develop and test hypotheses for this neglected, but important, combination. Results from an original survey experiment conducted in late June 2019 demonstrate that all respondents, as well as the Republican subgroup, tend to disapprove of a gay, religious candidate relative to other options (i.e., gay, nonreligious; straight, religious; and straight, nonreligious). Even Democrats expressed little support except when a straight, religious candidate was the alternative. Our findings underscore the need to study how overlapping—rather than discrete—traits influence political views and behaviors. They also raise important questions about the future of U.S. identity politics. Efforts to rally Republican and Democrat voters by mixing particular types of traits may not be a very effective strategy.     

The analysis of the homoerotic and the pursuit of meaning

This paper explores the dynamic tension between an evolving collective phenomenon and the nature of analytic process. Specifically, the focus will be erotic experiences which acquire a meaning through the culture at large, a meaning that may not be supportable when that material is subjected to psychological analysis. This stimulates a conflict between the symbolic attitude and the cultural perspective of the time. While the struggle between the individual and collective consciousness always emerges in analysis, the subject of same-gender sexual relations has become such a controversial and divisive issue in the current political environment that views toward homosexuality demand powerful allegiances and identification with either historic or contemporary ideas. People now identify as 'gay' and tend to see themselves as something akin to a race or perhaps alternative gender. Sexuality and relationship between same gendered people tends to be viewed through the lens of civil rights and the undeniable need for social equality. In this far-reaching and expanding collective phenomenon, psychology, in its support of human rights and accommodation to emerging trends, may be diminished in its capacity to pursue the meaning inherent in these human experiences. The position developed in this paper is that psychological experience, whether in the imaginal realm, dreams or personal consciousness, must be available for full analysis. Clinical experience and dreams are used to amplify this challenge to dynamic analytic practice.     

Coming Out, Visibility, and Creating Change: Empowering Lesbian, Gay, and Bisexual People in a Rural University Community

Personal and professional challenges faced in encouraging the development of a gay community in a rural university setting are described. Community psychologists who are lesbian, gay, or bisexual (LGB) must assess their willingness to be open and the roles they can play in developing helping resources. These issues concern how to encourage the empowerment of others while maintaining a collaborative role in a situation of major personal investment. Two specific challenges–developing informal helping resources for local LGB people and fostering institutional and policy changes to make the university a safer place for LGB faculty, staff, and students–are described. Community psychologists must consider personal risk when they become involved in empowerment efforts with this population.A white male community psychologist and a licensed clinical psychologist, I have been on the faculty of the Department of Human Development and Family Studies at Pennsylvania State University since 1972. I served as Faculty Adviser to the Lesbian, Gay, and Bisexual Student Alliance at the University for ten years, and worked extensively with lesbian, gay, and bisexual people in the local town, State College, PA, to develop community resources since the mid 1980’s. I had been granted tenure before the events described in this paper occurred.     

工作绩效与工作满意度、组织承诺和目标定向的关系

在全面回顾工作绩效及其影响因素的基础上,通过关键事件方法和问卷调查方法,对来自全国的1066位雇员进行了施测,运用AMOS软件,对工作绩效结构进行验证性因素分析,并对文中提出的假设进行了检验。之后,提出并验证了影响员工工作绩效的态度因素及整合模型。研究结果显示：工作满意度、组织承诺和目标定向对工作绩效的各个子维度的影响是不一致的。工作满意度越高,员工的工作绩效越好;另一方面,组织承诺和目标定向对雇员工作绩效各个子维度的影响不一致。文章最后对全文进行了总结,并对后续研究给出了建议     

A Test of Three Alternative Hypotheses Regarding the Effects of Early Delinquency on Adolescent Psychosocial Functioning and Substance Involvement

This study compared alternative hypotheses (from general deviance, life course, and developmental psychopathology perspectives) regarding the effects of early adolescent delinquency on psychosocial functioning in family, school, and peer contexts, and on alcohol use. Analyses also examined parent-child negative affective quality, prosocial school orientation, and peer substance use as possible direct predictors of problem substance use. Participants in this longitudinal study, extending from age 11 to age 18, were 429 rural teens (222 girls) and their families. Path model comparisons supported the tenability of a partial mediation model that included mediating pathways and a direct effect of delinquency on alcohol use, as hypothesized by developmental psychopathology. A supplemental analysis controlling for the stability of the family, school, and peer variables revealed that delinquency had less pervasive direct effects on, and a nonsignificant indirect effect through, changes in the mediators over time. Results also showed that peer substance use was a direct positive predictor of problem use.     

Affect sensitivity and affect regulation in dealing with positive and negative affect

Interactions between two types of affect sensitivity and two types of affect regulation were tested: low sensitivity to positive affect and high sensitivity to negative affect were expected to become maladaptive when self-motivation and self-relaxation are low, respectively. Consistent with expectations, specific Sensitivity × Regulation interactions emerged: low sensitivity to positive affect (i.e., independent, schizoid-like personality) was only associated with reduced emotional well-being when self-motivation was low. High sensitivity to negative affect (i.e., self-critical, avoidant-like personality) was only associated with psychosomatic symptoms when self-relaxation was low. In a subsample, the same results were obtained longitudinally. Findings support the distinction between affect sensitivity and affect regulation. Furthermore, affect regulation can be differentiated into self-motivation and self-relaxation.     

Procrastination: Different time orientations reflect different motives

Because procrastination concerns a person’s ability to meet deadlines, temporal dimension is clearly important to this personality construct. In the present study, the characteristic profile of arousal and avoidant motives of procrastinators were related to past, present, and future time conceptions. Participants (140 women, 135 men; mean age = 49.4, SD = 5.55) completed measures of arousal and avoidance procrastination, and time orientation. Results indicated that avoidant procrastination was associated negatively with present-fatalistic time orientation, and arousal procrastination was associated positively with present-hedonist and negatively with future time orientations. The variance accounted for by time orientations was modest, yet provides further evidence that there are distinct motives for chronic procrastination.     

Effects of Dangerous and Competitive Worldviews on Right-Wing Authoritarianism and Social Dominance Orientation over a Five-Month Period

The cross-lagged effects of dangerous and competitive social worldviews on Right-Wing Authoritarianism (RWA) and Social Dominance Orientation (SDO) were examined over a five-month period ( N   =  165). Analyses indicated that the motivational goal for group-based dominance and superiority indexed by SDO changed as a function of the degree to which the social world was perceived as a competitive place characterized by inequality and resource scarcity. The motivational goal for ingroup conformity and collective security indexed by RWA, in contrast, changed as a function of the degree to which the social world was perceived as a dangerous and threatening place prone to high levels of crime and immoral behavior. These findings are consistent with the causal pathways between social worldviews and ideological attitudes predicted by Duckitt's (2001 ) model of the dual motivational and cognitive processes underlying prejudice. An unexpected reciprocal effect in which RWA predicted longitudinal change in dangerous worldview was also identified, suggesting that the relationship between these two constructs may be more complex than previously hypothesized.     

Counselling psychologists in academia: Life satisfaction and work and family role commitments

We examined the life satisfaction of men and women counselling psychology faculty who were Division 17 (Society of Counseling Psychology) members of APA (American Psychological Association). Self-efficacy for multiple role management, coping style, and work-family role orientation were considered as predictors of life satisfaction. Results indicated that men scored significantly higher on employee role and self role self-efficacy as compared to women, and that women as compared to men scored higher on seeking social support coping. No significant sex difference was found for role orientation or life satisfaction. Findings revealed that spouse/partner self-efficacy and problem-solving coping emerged as significant predictors of men and women's life satisfaction and accounted for 31% of the total variance.
