BACKGROUND: Fear of cancer recurrence (FCR) is one of the largest unmet needs in the breast cancer survivor population. This review addresses this unmet need with the question. OBJECTIVES: The purpose of this article is to better understand potential interventions to manage FCR when caring for breast cancer survivors. METHODS: Databases used were PubMed, CINAHL®, Google Scholar, EMBASE, and Scopus.

Calorie restriction (CR), a reduction of 10ñ40% in intake of a nutritious diet, is often reported as the most robust non-genetic mechanism to extend lifespan and healthspan. CR is frequently used as a tool to understand mechanisms behind ageing and age-associated diseases. In addition to and independently of increasing lifespan, CR has been reported to delay or prevent the occurrence of many chronic diseases in a variety of animals. Beneficial effects of CR on outcomes such as immune function, motor coordination and resistance to sarcopenia in rhesus monkeys have recently been reported.

AIMS AND BACKGROUND: Research on the topic of hope began a long time ago but, more recently, interest in this construct has focused mainly on the development of psychometric tools for its assessment. The 2 steps of the present article are defining the construct of hope by completing a preliminary review of the literature and analyzing the tools used to assess hope in the setting of oncologic medicine, conducting a systematic review of the existing scientific literature. METHODS AND STUDY DESIGN: Our study was conducted in 2 stages.

Many variants that could be returned from genome sequencing may be perceived as ambiguous-lacking reliability, credibility, or adequacy. Little is known about how perceived ambiguity influences thoughts about sequencing results. Participants (n†=†494) in an NIH genome sequencing study completed a baseline survey before sequencing results were available. We examined how perceived ambiguity regarding sequencing results and individual differences in medical ambiguity aversion and tolerance for uncertainty were associated with cognitions and intentions concerning sequencing results.

A multi-armed bandit problem is a search problem on which a learning agent must select the optimal arm among multiple slot machines generating random rewards. UCB algorithm is one of the most popular methods to solve multi-armed bandit problems. It achieves logarithmic regret performance by coordinating balance between exploration and exploitation. Since UCB algorithms, researchers have empirically known that optimistic value functions exhibit good performance in multi-armed bandit problems.

Emotion (Washington, D.C.)

We are all faced with ambiguous situations daily that we must interpret to make sense of the world. In such situations, do you wear rose-colored glasses and fill in blanks with positives, or do you wear dark glasses and fill in blanks with negatives? In the current study, we presented 32 older and 32 younger adults with a series of ambiguous scenarios and had them continue the stories. Older adults continued the scenarios with less negativity than younger adults, as measured by negative and positive emotion word use and by the coded overall emotional valence of each interpretation.

The authors propose specific temporal profiles that reflect certainty versus doubt about where a partner stands with respect to a dating relationship over time. Two multiwave longitudinal studies focused on within-participant changes in perceived partner commitment. Results from multilevel modeling indicate that individuals whose perceptions of partner commitment fluctuate over time were more likely to be in a relationship that eventually ended than were individuals whose perceptions remained relatively steady.

Research has shown that intolerance of uncertainty (IU) - the tendency to react negatively to situations that are uncertain - is involved in worry and generalized anxiety disorder, as well as in other anxiety symptoms and disorders. To our knowledge, no studies have yet examined the association between IU and emotional distress connected with the death of a loved one. Yet, it seems plausible that those who have more difficulties to tolerate the uncertainties that often times occur following such a loss experience more intense distress.

This research qualifies a social psychological truism: that people like others who like them (the reciprocity principle). College women viewed the Facebook profiles of four male students who had previously seen their profiles. They were told that the men (a) liked them a lot, (b) liked them only an average amount, or (c) liked them either a lot or an average amount (uncertain condition). Comparison of the first two conditions yielded results consistent with the reciprocity principle. Participants were more attracted to men who liked them a lot than to men who liked them an average amount.

This article draws on the relational turbulence model to illuminate the dynamics of depression in romantic relationships using a thematic analysis of online discourse. Three content areas of relational uncertainty were apparent: (a) depression uncertainty (questions about physical harm, source of depression, and understanding), (b) self and partner uncertainty (questions about helplessness and identity), and (c) relationship uncertainty (questions about physical intimacy, relationship satisfaction, and the future of the relationship).
