Nursing Staff Knowledge and Attitudes Towards Deliberate Self-Harm in Adults and Adolescents in an Inpatient Setting

Abstract: Background: This paper investigates the relationship between care staff perceptions' of self-harm behaviours presented by adult and adolescent inpatients and the emotional responses and helping behaviours of the staff. Method: Seventy-six nursing staff participated, including qualified and unqualified staff, who worked in either adolescent or adult secure inpatient settings within a single organization. Participants completed vignette, knowledge, and attitudes questionnaires, related to working with patients who display deliberate self-harm. Results: Further support was found for attributional theories suggesting that views on deliberate self-harm are linked to propensity to help, and that emotional responses can be a mediating factor. Staff who reported feeling more negative about patients who self-harm reported more worry about working with this patient group. Unqualified nursing staff reported more negativity and worry than qualified staff. Neither gender nor length of work experience was found to be significant factors. Conclusions: These findings indicate that training and support should be aimed at helping nursing staff, particularly unqualified staff working in inpatient settings where self-harm is frequent, feel more positive and less concerned about working with patients who self-harm. Such needs of unqualified nursing staff have not been highlighted in previous research.

State hospital patients and their medication--do they know what they take?

Abstract: The author surveyed the population of a state hospital (N = 281) to ascertain the level of knowledge patients had about their medication. Approximately 8% of the patients correctly indicated the name of at least one medication they were taking, its dosage schedule, and its intended effect; approximately 54% of the patients evidenced no understanding of the medication they were regularly taking. Significant differences in understanding of medication were found as a function of diagnosis, age, and length of stay. The finding that few patients were knowledgeable about their medication raises doubts about recent court rulings on patients' competency to refuse medication.

Cohen–Macaulay Complexes and Koszul Rings

Abstract: Throughout this paper k denotes a fixed commutative ground ring. A Cohen–Macaulay complex is a finite simplicial complex satisfying a certain homological vanishing condition. These complexes have been the subject of much research; introductions can be found in, for example, Bjorner, Garsia and Stanley [6] or Budach, Graw, Meinel and Waack [7]. It is known (see, for example, Cibils [8], Gerstenhaber and Schack [10]) that there is a strong connection between the (co)homology of an arbitrary simplicial complex and that of its incidence algebra. We show how the Cohen–Macaulay property fits into this picture, establishing the following characterization.A pure finite simplicial complex is Cohen–Macaulay over k if and only if the incidence algebra over k of its augmented face poset, graded in the obvious way by chain lengths, is a Koszul ring.

Multi-period design of heat exchanger networks

Abstract: Heat exchanger networks are an integral part of chemical processes as they recover available heat and reduce utility consumption, thereby improving the overall economics of an industrial plant. This paper focuses on heat exchanger network design for multi-period operation wherein the operating conditions of a process may vary with time. A typical example is the hydrotreating process in petroleum refineries where the operators increase reactor temperature to compensate for catalyst deactivation. Superstructure based multi-period models for heat exchanger network design have been proposed previously employing deterministic optimisation algorithms, e.g. ( Aaltola, 2002 , Verheyen and Zhang, 2006 ). Stochastic optimisation algorithms have also been applied for the design of flexible heat exchanger networks recently ( Ma et al., 2007 , Ma et al., 2008 ). The present work develops an optimisation approach using simulated annealing for design of heat exchanger networks for multi-period operation. A comparison of the new optimisation approach with previous deterministic optimisation based design approaches is presented to illustrate the utilisation of simulated annealing in design of optimal heat exchanger network configurations for multi-period operation.
