Adaptive decision-making in buildingEXODUS in response to exit congestion

Given the importance of occupant behavior on evacuation efficiency, a new behavioral feature has been implemented into building EXODUS. This feature concerns the response of occupants to exit selection and re-direction, given that the occupant is queuing at an external exit. This behavior is not simply pre-determined by the user as part of the initialization process, but involves the occupant taking decisions based on their previous experiences with the enclosure and the information available to them. This information concerns the occupant's prior knowledge of the enclosure and line-of-sight information concerning queues at neighboring exits. This new feature is demonstrated and reviewed through several examples.

An improved approximation algorithm for the two-machine flow shop scheduling problem with an interstage transporter

We study the two-machine flow shop problem with an uncapacitated interstage transporter. The jobs have to be split into batches, and upon completion on the first machine, each batch has to be shipped to the second machine by a transporter. The best known heuristic for the problem is a –approximation algorithm that outputs a two-shipment schedule. We design a –approximation algorithm that finds schedules with at most three shipments, and this ratio cannot be improved, unless schedules with more shipments are created. This improvement is achieved due to a thorough analysis of schedules with two and three shipments by means of linear programming. We formulate problems of finding an optimal schedule with two or three shipments as integer linear programs and develop strongly polynomial algorithms that find solutions to their continuous relaxations with a small number of fractional variables

Exploring strategies for promoting the use of research findings in practice

Following the integration of nurse and midwifery education into institutions of higher education in the United Kingdom, a number of studies have shown that a defined clinical framework for nursing and midwifery lecturers in practice areas is lacking. The aim of this study was to explore strategies that nurse and midwifery lecturers from one higher education institution in south east England can use to work collaboratively with nurses and midwives to promote the utilization of research findings in practice. A cross-sectional survey using a structured questionnaire was sent to a sample of 60 nurse and midwifery lecturers and 90 clinical managers. Response rates of 67% (40) and 69% (62) respectively were obtained. The main strategies suggested were to make clinical staff more aware of what research exist in their specialties; to help them to access research information from research databases; and to critically appraise this information. Other strategies were for teachers to run research workshops on site; to undertake joint research projects with clinical staff; to set up journal clubs or research interest groups; and to help formulate clinical guidelines and protocols which are explicitly research-based.

The feedback we give: university student perceptions and preferences

This paper reports the results of a study on higher education student perceptions of and preferences for feedback on their performance. The issue of feedback to students is becoming increasingly important in higher education, not only because it is an important element of learning, but also as a significant component of the student experience and its evaluation. Within a mass education context, written feedback on coursework may be an important opportunity available to students for individualised attention. The current research explored perceptions of feedback by participants who were studying in undergraduate business degrees in a UK university (N=175). The survey instrument asked participants to evaluate the feedback they receive at university in terms of its impact and influence, as well as their understanding of feedback received and preferences. Analysis of the data indicates that students generally find feedback provided to them helpful and encouraging in improving their work but they also indicate that they would prefer to discuss their work directly with their tutor instead of receiving written feedback. They comment on the illegibility of some hand written feedback received. They also report that, generally, they act on the feedback received in order to improve their work and say that it helps them to reflect on their learning. Students comment that negative feedback received does not make them angry or demotivate them. The survey found considerable variability in the students' understanding of 'typical' feedback comments. The majority of students (79%) also reported that they prefer a structured feedback matrix to general comments because they consider it more specific and easier to understand. The implications of these findings for feedback and assessment practices are discussed and suggestions for improvements developed.

What a performance! Developing nurse teachers lecturing persona and identity: a performing arts perspective

Delivering lectures to large groups of students can provoke high levels of anxiety, particularly for new lecturers (Exley and Dennick, 2009). Further, to provide an informative and engaging lecture requires a teacher who is confident, has a sound knowledge and well developed teaching skills (Bentley-Davies, 2010). Thus, new lecturers often need experience and supervision to develop the tacit knowledge and insight into their own style and persona when teaching in order to feel confident when delivering a lecture (Quinn and Hughes, 2007). Considering this model, therefore, may potentially contribute to a lecturers’ development and performance in the classroom. This paper will present the results of the second phase of a two-stage mixed method study that investigated the similarities between lecturing and acting. Twelve in-depth interviews where undertaken with lecturers within one School of Nursing in The United Kingdom. Findings, established a model of ‘persona adoption’ that represents a series of stages that lecturers may go through to both develop and take on a persona when lecturing. This persona is often different from the way they lecturers present themselves in other parts of their working life. The first stage of this model of persona adoption is when the lecturer is subjected to a range of ‘influencing factors’ that provide not only the basic information about a lecture, but also the perceptual stimuli about giving a lecture on a specific subject, to a particular number of students, at a certain academic level. These influencing factors then inter-play with the ‘facets of the individual’, which represent the lecturer’s self-concept, subject knowledge base and philosophy of teaching. This may result in a cognitive dissonance between these ‘facets’ and the ‘influencing factors’, so affecting the lecturers’ perceptions, thoughts and feelings about having to give that particular lecture. This results in the lecturer undertaking specific ‘back stage preparation’ during which they decide on the content and modes of delivery to prepare in light of that discourse. It may result in delivering the information via single or multiple methods, which during the lecture will require various levels of interaction and participation from the students. Just prior to the lecture, the lecturer builds or ‘puts on their persona’ and gets into role, making their initial impact with the group. They use the ‘elements of acting’ as proposed by Tauber and Mester’s (1994) e.g. animated voice and body, space, props humour and suspense and surprise to portray and maintain their persona. This leads the to lecturer demonstrating either positive or negative ‘persona characteristics’ in terms of appearing confident, knowledgeable, fluent in the technical skills of delivering the lecture, being interesting and engendering interaction with the students, or not. These characteristics, may or may not, potentially heighten student interest, attention and attitudes to learning as suggested by Tauber and Mester (1994). This depends on whether the lecturer has successfully used the persona and if the lecturer has been able to engage students in the lecture, in competition with other factors that may be taking the students’ attention. Although the model suggests a linear process, to a great extent, the elements might be more interdependent and interrelated. This might suggest that depending on the lecturer’s perception of their effectiveness during the lecture, that they may decide to continue or adapt their persona and methods to appear more confident. Furthermore, depending on how successful the lecturer perceived the session to be, both their reflections ‘in’ and ‘on’ practice could influence how they teach in the future (Zwozdiak, 2011). Therefore, these reflections become part of the facets of the individual, via the ‘reflective feedback loop’, in the model, which then in turn influences progression through the model in subsequent lectures. This study concluded that these lecturers went through a process whereby they compare the demands of the lecture with their own knowledge base and skill, this resulted in them undertaking specific preparation in terms of content and delivery style, then they adopted their persona immediately prior to entering the lecture, maintain it throughout the lecture via the use of the elements of acting to achieve an informative interactive lecture. The results of which then feedback into their self-concept as a lecturer and consequently may affect the persona they project in future lectures. If lecturers, therefore, can take a step back to consider how they deliver lectures and the way they can deliberately, yet apparently naturally, use their voices, bodies, space and humour in meaningfully, they engage their students in lecture, it will not just result in them being perceived as a good lecturer, but also be a genuine act of education.

Coping, conversation tactics and marital interaction in persons with acquired profound hearing loss (APHL): correlates of distress

This study investigated coping strategies, conversation tactics, and marital interaction in acquired profound hearing loss (APHL) and compared emotionally stable (n = 15) and emotionally distressed (n = 7) participants. Nominated family members were assessed on most measures. Comparisons were also made in the subgroup of married participants. A combined distress criterion was derived from scores on standardized measures of anxiety, depression, hearing handicap, and post-traumatic stress. Groups were compared on the Ways-of-Coping Checklist, a newly devised measure of conversation tactics, and on the Couple Behaviour Report. It was found that distressed APHL participants were more likely to cope through avoidance, self-blame, and wishful thinking, and they used more avoidant tactics in conversation. The coping profile of family members did not differentiate distress groups. However, there was some indication of greater employment of coercive tactics by family members of distressed participants. The results are consistent with the view that the coping style of a person with APHL and the nature of their conversational interactions with family members contribute to their level of distress. Implications for audiological rehabilitation are discussed.

Sex talk? overcoming barriers about sex and contraception after childbirth

Anecdotal evidence tells professionals that childbirth is the best form of contraception. However, sexual health problems are the very common after childbirth with Barrett et al (2000) arguing that only 15% of women who have a postnatal sexual problem reported discussing it with a health professional. As health professionals with a predilection for the ‘clinical’ and the ‘prescriptive’ we organise antenatal classes to discuss bathing the baby and post partum reunions to recount birth stories, but often fail to address sexual health problems and contraception after birth.(Glazener 1997). Many women who have carefully used contraception for years prior to pregnancy are often not helped to re-engage with the issues following birth. This would seem to be a particular problem for the most vulnerable parents such as adolescent mothers and their partners (Social Exclusion Unit 1999, 2004) where some young women go on to have more than one baby in a short time period (Reeves 2003). The focus of this paper is to explore the apparent general failure of health professionals to discuss sex after childbirth and provide information regarding reliable contraception. Glazener (1997) tells us that health professionals are encouraged to educate and prepare patients antenatally, for example to be trained to identify problems and deal with them openly and sympathetically. What is brought into question is why this form of rigorous support is not extended to providing sexual health advice in the immediate and often vulnerable postnatal period and why this provision is not a priority for some groups. The paper will explore if this situation caused by a lack of training or is it a symptom of our culture and a British attitude towards sex and contraception.

Absence makes the professional try harder? Meeting the needs of socially excluded young men who become fathers

Research on socially excluded young fathers has been minimally addressed in the literature (SEU 1999, 2004). Indeed, research on young parents which informs health and social care professionals is often presented ‘through the eyes of the mother’ (Reeves 2006). Young parents in general and young fathers in particular are notoriously difficult to gain access to and engage with (Tyrer et al 2005) particularly if they have had previous negative involvement with the statutory services. Moreover, as Daniel and Taylor (1999, 2001, 2003) point out, professionals working in the health and care services often have an intense ‘maternal’ focus and this often excludes fathers from discussion and decisions about their children. The focus of this paper, drawing on two narrative studies of young fathers aged between 15-24 from the US and USA, is to evaluate the features of professional relationships that young fathers describe as finding helpful. Indeed, the findings discuss moving away from a culture of parenting classes, which all the young men interviewed described as finding problematical and in some cases embarrassing, to a culture of support which actively draws on their strengths and helps them become providers for their new families.

Social and demographic factors of young fathers in the UK and USA

Research on disadvantaged young fathers has been minimally addressed in the literature, particularly in the UK. In both countries teenage pregnancy rates are high and costly in terms of social policy and community provision. This paper explores 2 studies involving 24 young men with an average age of 17 on the transition to young fatherhood; one study was conducted in the UK with white young men and the other in the USA with black young men. The findings from both studies indicated common themes from their stories, particularly with regard to the high levels of disadvantage and social exclusion they had been exposed to in their demographic environments and the anti-social behaviour they described engaging in, prior to the birth of their child/ren. Specifically, a significant proportion of the young men described how they had been immersed in drug and gun crimes and how this shaped their lives and neighbourhoods. Becoming fathers is presented by both sets of young men as rescuing them from this criminal lifestyle.
