Presentists believe that only present things exist. Their theories, at first glance, seem to offer many admirable features: a simple ontology, and a meaningful, objective status for key temporal phenomena, such as the present moment and the passage of time. So intuitive is this theory that, as John Bigelow puts it, presentism was “believed by everyone...until at least the nineteenth century” (1996, p. 35). Yet, in the last 200 years presentism has been beset by criticisms from both physicists and metaphysicians. One of the most significant criticisms is that presentists cannot provide an acceptable system of truthmaking. If there is no past, how can there still be truths about the past? In this paper, I introduce a new theory of presentism, which addresses this problem in a novel way: by simply denying that there are any truths about the past. While prima facie an unintuitive position, I will argue that a sensible presentist philosophy of this kind can be described, so long as it is accompanied by an appropriate system of physics. I will also indicate at certain points that adopting presentism could allow us to understand fundamental physics in new, more intuitive ways. By the end of the paper, I hope to not only show that hard presentism is a defensible theory of time, but also that it could offer a number of advantages to the physicist and the philosopher alike.

Mentoring relationships are characterized by a sustained, high quality, and skill‐building relationship between a protégé and mentor (Handbook of Youth Mentoring, Los Angeles, SAGE, 2014). Within prevention science, youth mentoring programs emphasize creating a specific context that benefits a young person. Program‐sponsored relationships between youth and adults allow for creating a mentor–mentee partnership, but do not require the establishment of a strong bond in order to deliver prevention‐focused activities and experiences (Handbook of Youth Mentoring, Los Angeles, SAGE, 2014). Motivational Interviewing (MI) is a counseling style used widely to promote health behavior change and in prevention interventions. As part of an upstream approach to HIV prevention, we combined mentoring and MI by training peer mentors to use MI skills in their interactions as part of a large RCT of a mobile life skills intervention for adolescent men who have sex with men (AMSM). Our training model developed for training peer mentors in MI skills resulted in peers reaching and exceeding established MI fidelity thresholds (e.g., mean percentage of complex reflections = 80%, mean reflection to question ratio = 2.2:1). We offer reflections on lessons learned and future directions for those researchers and practitioners who may benefit from adapting this blended approach for mentoring AMSM. 相似文献
This study aims to evaluate the efficacy of a brief cognitive behavioral intervention program for children and adolescents experiencing persistent post-concussion symptoms. A total of 31 patients aged 10 to 18 years participated in the intervention. The median time since injury at treatment onset was 95 days though the range was large (23–720 days). Treatment was on average four sessions in duration. Sessions included concussion education, activity scheduling, sleep hygiene relaxation training, and cognitive restructuring. Outcomes were measured using symptom reports on the Sports Concussion Assessment Tool – Third Edition (SCAT-3) and parent-reported quality of life on the Pediatric Quality of Life Inventory (PedsQL). Mixed-effects models revealed that symptom reports did not decrease prior to the initiation of this treatment, though significant symptom improvement occurred following treatment. Quality of life scores significantly improved across domains, with the largest gains made in the emotional and school domains. Participant characteristics including age, sex, maternal education, and previous mental health problems were not found to be significantly related to treatment outcomes. Contrary to predictions, length of time since injury was not related to symptom changes. The primary limitation of this study is that it lacks randomization and an experimental control group. The results suggest that brief cognitive behavioral intervention may be a promising treatment for children and adolescents experiencing persistent post-concussive symptoms and warrants further investigation. 相似文献
Nitridoferrates containing monovalent iron ions are a class of materials of recent interest as potentially novel magnetic materials. Aiming at the exploration of nitridoferrates of calcium, we report the single crystal growth from Ca ?ux and crystal structure of the first member (n?=?2) of a series of inverse Ruddlesden-Popper nitrides with a general formula of An?1A'2BnX3n+1, where A?=?Li/Fe, A'?=?Te, B?=?N, and X?=?Ca. Single crystal X-ray diffraction analyses indicate the crystal with a composition of Ca7(Li0.32(1)Fe0.68(1))Te2N2 and the tetragonal space group I4/mmm (a?=?4.7884(1) Å, c?=?25.3723(4) Å, Z?=?2). The structure features alternately stacking NaCl-type A'X slabs and the perovskite-type ABX3 slabs along the c axis. The Li/Fe atoms are located in cuboctahedral cavities surrounded by eight Ca6N octahedra in the ABX3 slab. This work demonstrates the viability of the Ca-rich ?ux as a suitable solvent for the exploration of new complex nitrides with interesting crystal structure and properties. 相似文献
