In many Western welfare states, social work services that have traditionally been provided by paid employees are being replaced by family support, community support, informal networks and volunteering. For the field of social work, it is relevant to know what it matters to beneficiaries whether services are provided by volunteers or by paid employees. The central question of this article is therefore as follows: What are the differences between unpaid and paid social services for beneficiaries? The article is based on literature review and focus groups.Our results suggest that beneficiaries do experience some differences regarding the advantages of volunteer services for beneficiaries that can be summarized in three propositions: (1) Services provided by volunteers are more relational than are services provided by paid employees, and they are therefore perceived as more equal, flexible and sincere. (2) The effects of volunteer services for beneficiaries are not exclusively positive. (3) Although particular tasks may appear to be interchangeable to some extent, the relative advantages of a given task depend upon whether it is performed by a paid worker or by a volunteer. Additional research is needed in order to provide further validation.
The improvement of passive fire protection of storage vessels is a key factor to enhance safety among the LPG distribution chain. A thermal and mechanical model based on finite elements simulations was developed to assess the behaviour of full size tanks used for LPG storage and transportation in fire engulfment scenarios. The model was validated by experimental results. A specific analysis of the performance of four different reference coating materials was then carried out, also defining specific key performance indicators (KPIs) to assess design safety margins in near-miss simulations. The results confirmed the wide influence of coating application on the expected vessel time to failure due to fire engulfment. Aquite different performance of the alternative coating materialswas evidenced. General correlationswere developed among the vessel time to failure and the effective coating thickness in full engulfment scenarios, providing a preliminary assessment of the coating thickness required to prevent tank rupture for a given time lapse. The KPIs defined allowed the assessment of the available safety margins in the reference scenarios analyzed and of the robustness of thermal protection design.

4.1 IntroductionThe use of coercive measures generally has negative effects on patients. To help prevent its use, professionals need insight into what nurses believe about coercion and which staff determinants may influence its application. There is need for an integrated review on both attitude and influence of nurses on the use of coercion.4.2 AimTo summarize literature concerning attitude of nurses towards coercive measures and the influence of staff characteristics on the use of coercive measures.4.3 MethodSystematic review.4.4 ResultsThe attitude of nurses changed during the last two decades from a therapeutic to a safety paradigm. Nurses currently view coercive measures as undesirable, but necessary to deal with aggression. Nurses express the need for less intrusive interventions, although familiarity probably influences its perceived intrusiveness. Literature on the relation between staff characteristics and coercive measures is inconclusive.4.5 DiscussionNurses perceive coercive measures as unwanted but still necessary to maintain safety on psychiatric wards. Focussing on the determinants of perception of safety might be a promising direction for future research.4.6 Implications for practiceMental health care could improve the focus on the constructs of perceived safety and familiarity with alternative interventions to protect patients from unnecessary use of coercive interventions.
