Stress management competency framework in English policing
Background
The UK Health and Safety Executiveâs Stress Management Competency Framework and associated questionnaire, the Stress Management Competency Indicator Tool (SMCIT), address line managersâ behaviours across four competency areas. The application in policing remains unexplored.
Aims
This study profiled English police officersâ perception of their line managersâ competencies in the framework areas. The odds of experiencing poor mental wellbeing and work attitudes associated with having a line manager with a development need on each competency area were tested.
Methods
Two hundred and sixty-three police officers completed a survey comprising the SMCIT and measures of psychological distress, resilience and work engagement. Bivariate correlations were calculated to identify patterns of relationships between variables. Binary logistic regression analyses tested the odds of psychological distress caseness, low resilience and low work engagement being associated with officersâ perception of their line manager having a development need on the SMCIT criteria.
Results
Approximately half the participants reported their line manager had a development need on the âManaging and Communicating Existing and Future Workâ, âManaging the Individual Within the Teamâ and âReasoning and Managing Difficult Situationsâ competencies, and one quarter on the âRespectful and Responsible: Managing Emotions and Having Integrityâ competency. Officersâ rating of their line manager having a development need on the four competency areas was associated with up to four-fold elevated odds of each undesirable state.
Conclusions
The framework competency areas are relevant to English policing and offer a basis for stress reduction interventions targeted at line managersâ behaviours
English rural policing: job stress and psychological distress
Purpose
Job stressor exposure is associated with mental health in police officers. Police stress research rarely draws a distinction between urban and rural policing, raising the possibility that stressors specific to the rural context remain unidentified and their implications unknown. This may hinder actions to protect the mental health of those involved in policing rural communities.
Design/methodology/approach
Among rural policing teams in an English county police force this study used an exploratory sequential mixed method design to (1) identify and quantify exposure to rural policing stressors and (2) examine links between job stressor exposure and psychological distress.
Findings
Interviews (N = 34) identified three rural policing job stressor themes: (1) job demands, (2) isolation and (3) critical decisions. Survey data (N = 229) indicated significant differences in exposure by rank to demand and critical decision stressors, with police community support officers (PCSOs) reporting lower exposure than officers of constable and sergeant rank. Overall, 44% of respondents reported symptoms of psychological distress indicative of likely minor psychiatric disorder; higher levels of psychological distress were associated with higher stressor exposure across all three job stressor themes for PCSOs and constables and within the job demand theme for sergeants.
Originality/value
Findings point towards practical actions focussed on resource provision for officers and a research strategy to ameliorate the impact of stressors in English rural policing
Magma plumbing systems: a geophysical perspective
Over the last few decades, significant advances in using geophysical techniques to image the structure of magma plumbing systems have enabled the identification of zones of melt accumulation, crystal mush development, and magma migration. Combining advanced geophysical observations with petrological and geochemical data has arguably revolutionised our understanding of, and afforded exciting new insights into, the development of entire magma plumbing systems. However, divisions between the scales and physical settings over which these geophysical, petrological, and geochemical methods are applied still remain. To characterise some of these differences and promote the benefits of further integration between these methodologies, we provide a review of geophysical techniques and discuss how they can be utilised to provide a structural context for and place physical limits on the chemical evolution of magma plumbing systems. For example, we examine how Interferometric Synthetic Aperture Radar (InSAR), coupled with Global Positioning System (GPS) and Global Navigation Satellite System (GNSS) data, and seismicity may be used to track magma migration in near real-time. We also discuss how seismic imaging, gravimetry and electromagnetic data can identify contemporary melt zones, magma reservoirs and/or crystal mushes. These techniques complement seismic reflection data and rock magnetic analyses that delimit the structure and emplacement of ancient magma plumbing systems. For each of these techniques, with the addition of full-waveform inversion (FWI), the use of Unmanned Aerial Vehicles (UAVs) and the integration of geophysics with numerical modelling, we discuss potential future directions. We show that approaching problems concerning magma plumbing systems from an integrated petrological, geochemical, and geophysical perspective will undoubtedly yield important scientific advances, providing exciting future opportunities for the volcanological community
Mass Addition at Mount St. Helens, Washington, Inferred From Repeated Gravity Surveys
AbstractRelative gravity measurements were made at 12 sites on Mount St. Helens and 4 sites far afield during the summers of 2010, 2012, 2014, and 2016. Positive residual gravity changes of 0.05â0.06 ± 0.01 mGal from 2010 to 2016âa sign of mass additionâremain at proximal sites after accounting for the effects of changes in Crater Glacier shape and mass. Modeling of the 2010â2016 monitoring data indicates mass addition in the volcano magma reservoir, the volcano conduit, and/or the shallow hydrothermal aquifer. Magma intrusion in the volcano's known reservoir is suggested by the joint inversion of GPS and gravity data (d = 5800 ± 710 m below sea level, ÎVm = 49.8 ± 8.6 Ă 106m3, Ï = 1930 ± 300 kg/m3); the modeled depth and location are consistent with that of the reservoir that fed the 2004â2008 eruption, and its mass change can explain up to 19% of the residual gravity. The other two potential sourcesâthe conduit and shallow aquiferâare not well constrained. Magma addition along the volcano conduit can explain up to 62% of the residual gravity (ÎVm â
31 Ă 106m3, âÏm â
2, 300 kg/m3). However, such an intrusion should have produced a measurable surface deformation, which is not observed in the GPS time series. Changes in the level of the volcano's shallow hydrothermal system (Ïw = 1, 000 kg/m3) can explain 17% (ÎVrecharge â
9 Ă 106m3) to 61% (ÎVrecharge â
30 Ă 106m3) of the residual gravity. It would therefore seem that the bulk of the mass change measured at Mount St. Helens during 2010â2016 was caused by shallow accumulation of water beneath the floor of the crater

United States Geological Survey Reports
From abstract: The Wabayuma Peak Wilderness Study Area (AZ-020-037/043), for which a mineral survey was requested by the U.S. Bureau of Land Management, encompasses 40,118 acres in northwestern Arizona. Fieldwork was carried out in 1986-88 by the U.S. Bureau of Mines and the U.S. Geological Survey to appraise the identified (known) resources and assess the mineral resource potential (undiscovered) of the wilderness study area. Within the Wabayuma Peak Wilderness Study Area are 14 private parcels of land totaling 1,315 acres. The Wabayuma Peak Wilderness Study Area, including the 14 private parcels of land, is herein referred to as the "wilderness study area" or the "study area." The Boriana, Antler, and Copper World mines lie near the east boundary of the study area. The Boriana mine was a major tungsten-producing mine of the United States during World War II. The Antler and Copper World mines produced relatively small amounts of copper and zinc prior to 1970
