Mapping the structural characteristics of attack behavior, this study explores how violent conflict evolved with the implementation of civil gang injunctions (CGIs). Networks were generated by linking defendants and victims named in 963 prosecutions involving street gangs active in the City of Los Angeles (1998–2013). Aggregating directed ties to 318 groups associated with the combatants, we compare four observations that correspond with distinct phases of CGI implementation—development (1998–2001), assent (2002–2005), maturity (2006–2009), and saturation (2010–2013). Using a triad census to calculate a ratio of simple patterns (retaliation, directed lines, and out-stars) to complex three-way interactions, we observed that CGIs were associated with a substantive thickening of conflict—greater complexity was found in conflict relations over time. Dissecting the nature of change, stochastic actor-oriented models (SAOMs) show that enjoined gangs are more likely to initiate transitive closure. The findings suggest that crime control efforts must make regular adjustments in response to the evolving structure of gang interactions.

Comparing the centrality of gangs and changing structure in attack behavior, this study examines the effects of civil gang injunctions (CGIs) on violence involving 23 gangs (seven Bloods and 16 Crips) operating in Southern California. We mapped violence networks by linking defendants and victims named in 272 court cases prosecuted in the City of Los Angeles (1997-2015), involving at least one conviction for a violent crime and a defendant tried as an adult. The results show that a small number of gangs are centrally located in a dynamic web of non-reciprocated conflict that exhibited complex hierarchical structures. These results raise four implications for combating gang violence.

The pattern of BSA-Au uptake in vivo by endothelial cells of the venous sinuses (sinusoidal cells) of rat bone marrow has been described previously. BSA-Au conjugates are taken up exclusively in coated pits and vesicles, enter and pass through an “endosomal” compartment comprised of smooth-membraned tubules and vacuoles and cup-like bodies, and subsequently reside in multivesicular and dense bodies. The process is very rapid, with BSA-Au reaching secondary lysosmes one minute after presentation. (Figure 1)In further investigations of this process an isolated limb perfusion method using an artificial blood substitute, Oxypherol-ET (O-ET; Alpha Therapeutics, Los Angeles, CA) was developed. Under nembutal anesthesia, male Sprague-Dawley rats were laparotomized. The left common iliac artery and vein were ligated and the right iliac artery was cannulated via the aorta with a small vein catheter. Pump tubing, preprimed with oxygenated 0-ET at 37°C, was connected to the cannula.

Purpose To effectively prepare students to engage in interprofessional practice, a number of Communication Disorders (COMD) programs are designing new courses and creating additional opportunities to develop the interprofessional competencies that will support future student success in health and education-related fields. The ECHO (Educational Community Health Outreach) program is one example of how the Rongxiang Xu College of Health and Human Services at California State University, Los Angeles, has begun to create these opportunities. The ultimate goal of the ECHO project is to increase both access to and continuity of oral health care across communities in the greater Los Angeles area. Method We describe this innovative interdisciplinary training program within the context of current interprofessional education models. First, we describe the program and its development. Second, we describe how COMD students benefit from the training program. Third, we examine how students from other disciplines experience benefits related to interprofessional education and COMD. Fourth, we provide reflections and insights from COMD faculty who participated in the project. Conclusions The ECHO program has great potential for continuing to build innovative clinical training opportunities for students with the inclusion of Child and Family Studies, Public Health, Nursing, and Nutrition departments. These partnerships push beyond the norm of disciplines often used in collaborative efforts in Communication Sciences and Disorders. Additionally, the training students received with ECHO incorporates not only interprofessional education but also relevant and important aspects of diversity and inclusion, as well as strengths-based practices.

Traumatische Ereignisse im schulischen Kontext treten vergleichsweise häufig auf. So ist die Bestimmung von Kindern und Jugendlichen, die aktuell und auch zu einem späteren Zeitpunkt einer psychologischen Betreuung bedürfen, im Rahmen der Fürsorgepflicht notwendig. 48 Jugendliche zwischen 12 und 17 Jahren wurden in der Schule zu zwei Messzeitpunkten zur akuten und posttraumatischen Symptomatik sowie zu verschiedenen Risikofaktoren befragt. Verwendet wurde die neu entwickelte Checkliste zur Akuten Belastung (CAB) und die deutsche Version des University of Los Angeles at California Posttraumatic Stress Disorder Reaction Index (UCLA CPTSD-RI). Eine Woche nach dem Ereignis betrug der Anteil klinisch bedeutsamer Belastung 21 % und nach 10 – 15 Wochen 10 %. Ein mittlerer Zusammenhang zwischen akuter und posttraumatischer Belastung konnte nachgewiesen werden. Als bedeutsame Risikofaktoren für die Entwicklung einer posttraumatischen Belastung stellten sich der Konfrontationsgrad, peritraumatisch erlebte Angst sowie akute Beeinträchtigung heraus. Im Kontext der Betreuung betroffener Jugendlicher nach traumatischen Ereignissen sollte den Risikofaktoren mehr Beachtung geschenkt werden.
