Abstract

Purpose

The joint photographic experts group (JPEG) 2000 image compression system is being used for cultural heritage preservation. The authors are aware of over a dozen of big memory institutions worldwide using this format. This paper aims to review and explain choices for end users to help resolve trade-offs that these users are likely to encounter in practice.

Design/methodology/approach

The JPEG 2000 format is quite complex and therefore sometimes considered as a preservation risk. A lossy compression is governed by a number of parameters that control compression speed and rate-distortion trade-off. Their inappropriate adjustment may fairly easily lead to sub-optimal compression performance. This paper provides general guidelines for selecting the most appropriate parameters for a specific application.

Findings

This paper serves as a guide for the preservation of digital heritage in cultural heritage institutions, including libraries, archives and museums.

Abstract

Purpose

Violence toward frontline health-care workers (HCWs) from patients and visitors is a pervasive issue that ranges from verbal and psychological abuse to physical assault. The emergence of the COVID-19 pandemic has led to increased reports of escalated verbal workplace aggressions (VWPAs); however, most studies have been conducted internationally. Studies based in the USA have focused on physical violence experienced by nurses and paramedics in emergency situations. The purpose of this study is to learn about the experiences of different levels of frontline HCWs with VWPA from patients and visitors and discover ways to address this issue.

Design/methodology/approach

This qualitative descriptive study asked registered nurses, licensed practical nurses and patient care technicians from one health-care system about their experiences with patient and visitor VWPA using an anonymous, voluntary open-ended survey and in-person interviews. In all, 31 participants completed the survey and 2 were interviewed. Data were analyzed using content analysis.

Findings

Three themes emerged from the data: the experience, moving through and moving forward. Frontline HCWs described experiences of VWPA, indicating its forms, frequency and conditions. They used coping, along with personal and professional measures, to manage and move through the situation. Moving forward was captured as suggestions for the future and conveyed hope for a perfect state.

Originality/value

The experiences of frontline HCWs offered insight into how they perceive and cope with difficult encounters. Recommendations relate to not only implementing interventions that support frontline HCWs but also creating a culture where aggression is not tolerated and addressing perpetrator behavior is a priority.
