Informational masking is broadly defined as a degradation of auditory detection or discrimination of a signal embedded in a context of other similar sounds; it is not related to energetic masking caused by physical interactions between signal and masker. In this paper, we report a systematic release from informational masking of a target tone in a nine-tone rapid auditory sequence as the target is increasingly isolated in frequency or intensity from the remaining sequence components. Improved target-tone frequency difference limens as isolation increases are interpreted as a reflection of increasingly focused auditory attention. The change from diffuse to highly focused attention is gradual over the frequency and intensity ranges examined, with each I-dB increment in target intensity relative to the remaining components producing performance improvements equivalent to those produced by a 2% increase in frequency isolation. The results are modeled as bands of attention in the frequency and intensity domains. For attention directed by frequency isolation, there is a strong correspondence with auditory filters predicted by the power spectrum model of masking. These data also support the existence of an attention band of intensity, with a bandwidth of about 5-7 dB at the moderate levels used in this experiment.

Purpose Communities are best able to tackle complex social problems when solutions are achieved collaboratively. Inter-organizational partnerships are strongest and provide the greatest benefit to communities when the relationships are mutually compatible. The purpose of this paper is to introduce an evidence-informed approach to identifying and forming mutually compatible collaborations among organizations responsible for promoting community well-being and carrying out community-level interventions. Design/methodology/approach A three-stage case study examines the utility of a novel measurement tool for identifying opportunities for strategic collaboration. The strategic compatibility assessment (SCA) was designed to identify inter-organizational collaborative capacities within and across sectors as a means to motivate collaborative behaviors that are essential to community change initiatives that advance the collective impact. Findings The findings of this paper indicate the SCA is an effective tool for fostering mutually beneficial collaborative partnerships. A high degree of content, face and practical validity was evidenced in two independent studies of SCA, and organizations using the SCA tool reported a moderate-to-high degree of collaborative behavior in a post-intervention assessment of SCA outcomes. These findings provide field-based support for the SCA to promote cross-sector collaboration for community-level interventions. Originality/value The SCA tool describes the degree of collaboration among organizations that operate within a neighborhood; identifies potential points of mutual compatibility within the network; and creates pathways for leveraging collaborative behavior to promote community capitals. The aim of this research is to examine the potential of the SCA tool to shift the non-profit sector climate away from one characterized by competition toward one rich with collaboration.

Highlights • This study highlights the utility of CBPR and implementation science for crime/violence prevention. • Through cross-sector partnerships, the nature and scope of community crime/violence were assessed. • Findings highlighted an active drug market, high-stress, concern for youth, and lack of trust in police.

The social work profession is a helping profession; social workers provide services with the intent to improve life opportunities in pursuit of social justice for individuals, groups, communities, and society as a whole. Social workers are called to work on behalf of the most vulnerable people in our society, and as such, the hazards of our helping profession are abundant. Though the literature offers numerous frameworks that can be used by social workers in a variety of settings, many issues that are unique to community practice settings can lead to professional burnout and compassion fatigue for social workers. At present there are no comprehensive models for self-care that attend specifically to the unique needs of the community practitioner. This article presents the iM-PAACT model, a four-part conceptual framework that helps to fill this gap in the literature. This practical self-care model has been designed specifically for social workers engaged primarily in community practice settings, including the community activist, community organizer, and community-engaged scholar.
