Time Perspective Therapy: A New Time-Based Metaphor Therapy for PTSD

Abstract: Time perspective therapy (TPT) is a new time-based therapy that focuses on clients' perceptions of their past, present, and future. Based on Zimbardo's temporal theory and the utilization of the Zimbardo Time Perspective Inventory, the authors have developed this new narrative therapy approach for the purpose of treating clients diagnosed with posttraumatic stress disorder. The goal of TPT is to identify clients' six time perspective factors and then work with and balance these perspectives to promote a more positive future orientation, replace their traumatic past negativity, and thereby create a more responsive and healthier individual.

Examining the types of social support and the actual sources of support in older Chinese and Korean immigrants.

Abstract: This study explored social support domains and actual sources of support for older Chinese and Korean immigrants and compared them to the traditional domains based on mainly White, middle class populations. Fifty-two older Cantonese and Korean speaking immigrants participated in one of eight focus groups. We identified four similar domains: tangible, information/advice, emotional support, and companionship. We also identified needing language support which is relevant for non-English speaking minority populations. Participants discussed not needing emotional support. These Chinese and Korean immigrants had a small number of actual sources of support, relying mainly on adult children for help with personal situations (e.g., carrying heavy groceries, communicating with physicians) and friends for general information/advice (e.g., learning how to speak English, applying for citizenship) and companionship. Immigrant Asians are caught between two different traditions; one that is strongly kinship oriented where needs and desires are subordinated to the interests of the family and one that values independence and celebrates individuality. Despite their reticence in asking for help outside the family, elders are seeking help from other sources, such as ethnic churches and the government.

Leveraging Citizen Science and Information Technology for Population Physical Activity Promotion

Abstract: Purpose While technology is a major driver of many of society's comforts, conveniences, and advances, it has been responsible, in a significant way, for engineering regular physical activity and a number of other positive health behaviors out of people's daily lives. A key question concerns how to harness information and communication technologies (ICT) to bring about positive changes in the health promotion field. One such approach involves community-engaged "citizen science," in which local residents leverage the potential of ICT to foster data-driven consensus-building and mobilization efforts that advance physical activity at the individual, social, built environment, and policy levels. Method The history of citizen science in the research arena is briefly described and an evidence-based method that embeds citizen science in a multi-level, multi-sectoral community-based participatory research framework for physical activity promotion is presented. Results Several examples of this citizen science-driven community engagement framework for promoting active lifestyles, called "Our Voice", are discussed, including pilot projects from diverse communities in the U.S. as well as internationally. Conclusions The opportunities and challenges involved in leveraging citizen science activities as part of a broader population approach to promoting regular physical activity are explored. The strategic engagement of citizen scientists from socio-demographically diverse communities across the globe as both assessment as well as change agents provides a promising, potentially low-cost and scalable strategy for creating more active, healthful, and equitable neighborhoods and communities worldwide.

A Long‐Period Jupiter‐Mass Planet Orbiting the Nearby M Dwarf GJ 849

Abstract: We report precise Doppler measurements of GJ 849 (M3.5 V) that reveal the presence of a planet with a minimum mass of 0.82M_Jup in a 5.16 yr orbit. At AU, GJ 849b is the first Doppler‐detected planet discovered around an M dwarf orbiting beyond 0.21 AU, and is only the second Jupiter‐mass planet discovered around a star less massive than 0.5 M_⊙. This detection brings to four the number of M stars known to harbor planets. Based on the results of our survey of 1300 FGKM main‐sequence stars we find that giant planets within 2.5 AU are ∼3 times more common around GK stars than around M stars. Due to GJ 849’s proximity of 8.8 pc, the planet’s angular separation is 0.27 , making this system a prime target for high‐resolution imaging using adaptive optics and future space‐borne missions such as the Space Interferometry Mission PlanetQuest. We also find evidence of a linear trend in the velocity time series, which may be indicative of an additional planetary companion.

Abruptly autofocusing and autodefocusing optical beams with arbitrary caustics

Abstract: We propose a simple yet efficient method for generating abruptly autofocusing optical beams with arbitrary caustics. In addition, we introduce a family of abruptly autodefocusing beams whose maximum intensity suddenly decreases by orders of magnitude right after the target. The method relies on appropriately modulating the phase of a circularly symmetric optical wavefront, such as that of a Gaussian, and subsequently on Fourier-transforming it by means of a lens. If two such beams are superimposed in a Bessel-like standing wave pattern, then a complete mirror-symmetric, with respect to the focal plane, caustic surface of revolution is formed that can be used as an optical bottle. We also show how the same method can be used to produce accelerating 1D or 2D optical beams with arbitrary convex caustics.
