Government policy and organizational factors influence family focused practice in adult mental health services. However, how these aspects shape psychiatric nurses’ practice with parents who have mental illness, their dependent children and families is less well understood. Drawing on the findings of a qualitative study, this article explores the way in which Irish policy and organizational factors might influence psychiatric nurses’ family focused practice, and whether (and how) family focused practice might be further promoted. A purposive sample of 14 psychiatric nurses from eight mental health services completed semi-structured interviews in 2013. The analysis was inductive and presented as thematic networks. Both groups described how policies and organizational culture enabled and/or hindered family focused practice, with differences between community and acute participants seen. The need to develop national and international policies along with practices to embed information and support regarding parenting into ongoing care is implicated in this study.

This manuscript describes the application and further development of the TAP technique in kinetic characterization of heterogeneous catalysis. The major application of TAP systems is to study mechanisms, kinetics and transport phenomena in heterogeneous catalysis, all of which is made possible by the sub-millisecond time resolution. Furthermore, the kinetic information obtained can be used to gain an insight into the mechanism occurring over the catalyst system. This is advantageous as heterogeneous catalysts with an improved efficiency can be developed as a result. TAP kinetic studies are carried out at low pressure (~1x10-7 mbar) and TAP pulses are sufficiently small (1013-1015 molecules) so as to maintain this low pressure. The use of a small number of molecules in comparison to the total number of active sites means the state of the catalyst remains relatively unchanged. The use of the low intensity pulses also makes the pressure gradient negligible and so allows the TAP reactor system to operate in the Knudsen Diffusion regime, where gas-gas reactions are eliminated. Hence only gas-catalyst reactions are investigated and, by the use of moment analysis of observed exit flow, rate constants of elementary steps of the reaction can be obtained.
In this manuscript, two attempts to further the TAP technique are reported. Firstly, the work undertaken at QUB to attempt to control the number of molecules of condensable reagents that can be pulsed during a TAP pulse experiment is disclosed. Secondly, a collaborative project with SAI Ltd Manchester is discussed in a separate chapter, where technical details and validation of a customised time of flight mass spectrometer (ToF MS) for the QUB TAP-1 system are reported. A collaborative project with Cardiff Catalysis Institute focusing on the study of CO oxidation over hopcalite catalysts is also reported. The analysis of the experimental results has provided an insight into the possible mechanism of the oxidation of CO over these catalysts. A correction function has also been derived which accounts for the adsorption of reactant molecules over inert materials that are used for the reactor packing in TAP experiments. This function was then applied to the selective reduction of O2 in a H2 rich ethene feed, so that more accurate TAP moment based analysis could be conducted.

The development and optimization of catalysts and catalytic processes requires knowledge of reaction kinetics and mechanisms. In traditional catalyst kinetic characterization, the gas composition is known at the inlet, and the exit flow is measured to determine changes in concentration. As such, the progression of the chemistry within the catalyst is not known. Technological advances in electromagnetic and physical probes have made visualizing the evolution of the chemistry within catalyst samples a reality, as part of a methodology commonly known as spatial resolution. Herein, we discuss and evaluate the development of spatially resolved techniques, including the evolutions and achievements of this growing area of catalytic research. The impact of such techniques is discussed in terms of the invasiveness of physical probes on catalytic systems, as well as how experimentally obtained spatial profiles can be used in conjunction with kinetic modelling. Furthermore, some aims and aspirations for further evolution of spatially resolved techniques are considered.

Introduction: While it is recommended that mental health professionals engage in family focused practice (FFP), there is limited understanding regarding psychiatric nurses’ practice with parents who have mental illness, their children and families in adult mental health services.
Methods: This study utilized a mixed methods approach to measure the extent of psychiatric nurses’ family focused practice and factors that predicted it. It also sought to explore the nature and scope of high scoring psychiatric nurses’ FFP and factors that affected their capacity to engage in FFP. Three hundred and forty three psychiatric nurses in 12 mental health services throughout Ireland completed the Family Focused Mental Health Practice Questionnaire (FFMHPQ). Fourteen nurses who achieved high scores on the FFMHPQ also participated in semi-structured interviews.
Results: Whilst the majority of nurses were not family focused a substantial minority were. High scoring nurses’ practice was complex and multifaceted, comprising various family focused activities, principles and processes. Nurses’ capacity to engage in FFP was determined by their knowledge and skills, working in community settings and own parenting experience.
Conclusions: Generally, low levels of family focused practice suggest the need for organizations to develop and implement guidelines, policies and training to support mental health professionals to adopt a whole family approach.

As alterações introduzidas pela actual reforma da Administração Pública preconizam uma gestão determinada por objectivos motivando os trabalhadores para um desempenho de qualidade reconhecendo o mérito e a excelência. A avaliação de desempenho dos enfermeiros regulamentada desde 1993, estabelece como princípios orientadores a objectividade, a continuidade, a flexibilidade e a periodicidade, em que a atribuição de uma menção qualitativa resulta da avaliação contínua centrada no conteúdo funcional de cada categoria profissional. A abordagem da justiça organizacional justifica-se, tendo em conta os efeitos das percepções de (in)justiça nas atitudes e comportamentos das pessoas. Essas reacções podem ter efeitos directos e indirectos no funcionamento dos grupos e da organização. Neste contexto, surge este estudo, não experimental, transversal e correlacional de tipo quantitativo, para o qual definimos como objectivos fundamentais: conhecer o nível de satisfação dos enfermeiros com o processo de avaliação de desempenho e variáveis relacionadas; avaliar a percepção de justiça organizacional dos enfermeiros e analisar as possíveis relações entre a satisfação com o processo de avaliação de desempenho e a percepção de justiça organizacional Os dados foram obtidos, através da aplicação de um questionário aos enfermeiros do Hospital em estudo e concluímos que, os enfermeiros avaliam positivamente o nível de satisfação com o processo de avaliação de desempenho, com valores superiores na dimensão comportamental, referente aos aspectos interaccionais do que na dimensão cognitiva, relacionada com os aspectos procedimentais. Os enfermeiros chefes são a categoria profissional com nível mais baixo de satisfação na dimensão referente aos aspectos interaccionais. A análise dos dados referentes ao nível de finalização das diferentes fases do processo de avaliação indicam uma clara descontinuidade dado que, apenas 23,8% dos enfermeiros participa na elaboração das normas e critérios e, inversamente, 97,6% elaboraram o relatório crítico de actividades sendo este o documento de suporte documental que permite a atribuição da menção qualitativa reforçando assim as críticas de burocratização do processo. Relativamente à percepção de justiça organizacional verificamos que a vertente distributiva é a que apresenta valores mais baixos sendo a vertente interaccional aquela em que se verifica valores médios mais elevados. Verificámos existirem correlações positivas e significativas entre as dimensões procedimental e interaccional da percepção de justiça, quer para a dimensão cognitiva quer para a dimensão comportamental do nível de satisfação com a avaliação de desempenho dos enfermeiros. O estudo reforça a convicção de que o processo de avaliação de desempenho deve ser mantido tal como regulamentado, devendo os esforços serem canalizados para corrigir os aspectos referentes à precisão com que o processo avalia o desempenho e o cumprimento de todas as etapas o que só se consegue com a participação reflectida na adesão a um sistema de valores que privilegie a qualidade e definição de indicadores de produtividade e qualidade dos cuidados de enfermagem.

The purpose of this study is to explore the humorous side of television advertisement and its impact on Portuguese consumers’ hearts, minds and wallets. Both qualitative (through in-depth interviews) and quantitative (through an on-line survey and subsequent statistical data analysis) methods were used, guaranteeing a more consistent, strong and valid research. Twenty-five interviews with randomly chosen consumers were conducted face-to-face and three interviews via e-mail with marketers and television advertisers were performed in order to explore profoundly the subject. Moreover, 360 people have answered the on-line survey. Through the analysis of the data collected humor perception was found to be positively correlated with persuasion and intention to purchase the product; intention to share the advert; message comprehension; product liking and development of positive feelings towards the brand and brand credibility variables. The main implication of these findings relies on the fact that humor in advertising is able to boost its effectiveness.

In the framework of health services research sponsored by the Swiss National Science Foundation, a research was undertaken of the activity of the large majority of the public health nurses working in the Swiss cantons of Vaud and Fribourg (total population 700,000). During one week, 130 nurses gathered, with a specially devised instrument, data on 4165 patient visits. Studying the duration of the contacts, one has distinguished contact duration per se (DC), duration of the travel time preceding the contact (DD), and total duration in relation with the contact (DTC-addition of the first two). It was noted that the three durations increased significantly with patient age (as regard travel time, this is explained by the higher proportion of home visits in higher age groups, as compared with visits at a health center). Examined according to location of the visit, contact duration per se (without travel) is higher for visits at home and in nursing homes than for those taking place at a health center. Looked at in respect to the care given (technical care, or basic nursing care, or both simultaneously), our data show that the provision of basic nursing care (alone or with technical care) doubles contact duration (from 20 to 42-45'). The analyses according to patient age shows that, at an advanced age (beyond 80 years particularly), there is an important increase of the visits where both types of care are given. However, contact duration per se shows a significant raise with age only for the group "technical care only"; it can be demonstrated that this is due to the fact that older patients require more complex technical acts (e.g., bladder care, as compared with simpler acts such as injection). A model of the relationships between patient age and contact duration is proposed: it is because of the increase in the proportions of home visits, of visits including basic nursing care, and of more complex technical acts that older persons require more of the working time of public health nurses.

A number of synthetically useful ring systems can be prepared via the intramolecular insertion of a metal-stabilized carbenoid into a heteroaromatic systems. The chemical outcome of these reactions are dependent not only on the nature of the heteroatom but also on the length of the aliphatic tether linking the carbenoid moiety with the aromatic fragment. Our work with furanyl and thienyl systems containing a single methylene tether have allowed for some rather atypical chemistry. For example, treatment of l-diazo-3-(2-thienyl)-2-propanone (6) with catalytic rhodium (II) acetate yields 5,6- dihydro-4^-cyclopenta[Z>]thiophen-5-one (3) while, the isomeric l-diazo-3-(3-thienyl)-2- propanone(15) gives a spiro-disulphide (20). Novel chemistry was also exhibited in the analogous furanyl systems. While treatment of l-diazo-3-(3-furanyl)-2-propanone (52) with Rh2(OAc)4 resulted in the expected 2-(4-Oxo-2-cyclopentenyliden)acetaldehyde (54), isomeric l-diazo-3-(2- furanyl)-2-propanone (8) undergoes vinylogous Wolff rearrangement to give a mixture of 6a-methyl-2,3,3a,6a-tetrahydrofuro[2,i-^>]furan-2-one (44) and 2-(2-methyl-3-furyl)acetic acid (43). Rhodium acetate catalyzed decomposition of l-diazo-3-(3-benzofuranyl)-2- propanone (84) and l-diazo-3-(2-benzofuranyl)-2-propanone (69)also allows for vinylogous Wolff rearrangement, a chemistry unseen in benzofuranyl systems with longer tethers. A number of interesting products were isolated from the trapping of intermediate ketenes. Decomposition of l-diazo-3-(3-benzothienyl)-2-propanone (100) resulted in the formation of 2,3-dihydro-l//-benzo[^]cyclopenta[^thiophen-2-one (102). However, in addition to (102), a dimer was also generated from the decomposition of l-diazo-3-(2- benzothienyl)-2-propanone (109). The insight into the mechanistic underpinnings of the above reactions are provided by molecular modeling at a PM3 level.

This research provided relevant data to support pain research literature that finds nurses do not have the knowledge base that they require to sufficiently provide effective pain management. The data demonstrated that nurses have mixed attitudes toward pain. These two findings have been observed in the literature for more than 20 years, but were important results for the hospitals and the nurses involved in the study. The purposes of this study were to identify the level of knowledge and attitudes in a sample of nurses fi-om the surgical and medical units in three hospitals, and determine whether a difference between these two groups existed. The institutional resources to support pain relief practices provided by each hospital were also documented. Data were collected using a convenience sample from the medical and surgical units of three hospitals. Ofthe 1 13 nurses who volunteered to participate, 78 worked in surgical units and 35 worked in medical units. Demographic data were collected about the participants. The established instruments used to obtain data about knowledge and attitude included: (a) Nurses Knowledge of Pain Issues Survey, (b)Attitude to Pain Control Scale, and (c) Andrew and Robert Vignette. Data collected were quantitative along with two open-ended questions for a rich, qualitative section. Inadequate knowledge and outdated attitudes were very evident in the responses. Data from the open-ended questions described how nurses assessed pain and the most conmion problems caring for patients in pain. Nursing practice implications for these hospitals involve initiating a process to develop an educational pain program for nurses throughout the hospital. Utilizing findings from other studies, the program should have an interdisciplinary approach to the planning, implementation, evaluation, and ongoing support. This study supports the belief that inadequate pain management has been attributed to many factors, most importantly to a lack of knowledge. Pain is a costly, unnecessary complication for the patient as well as the hospital. It follows then, that it is in the best interest of all involved to implement an educational pain program in order to influence practice.

The effectiveness of various kinds of computer programs is of concern to nurse-educators. Using a 3x3 experimental design, ninety second year diploma student nurses were randomly selected from a total population at three community colleges in Ontario. Data were collected via a 20-item valid and reliable Likert-type questionnaire developed by the nursing profession to measure perceptions of nurses about computers in the nursing role. The groups were pretested and posttested at the beginning and end of one semester. Subjects attending College A group received a computer literacy course which comprised word processing with technology awareness. College B students were exposed to computer-aided instruction primarily in nursing simulations intermittently throughout the semester. College C subjects maintained their regular curriculum with no computer involvement. The student's t-test (two-tailed) was employed to assess the attitude scores data and a one-way analysis of variance was performed on the attitude scores. Posttest analysis revealed that there was a significant difference (p<.05) between attitude scores on the use of computers in the nursing role between College A and C. No significant differences (p>.05) were seen between College B and A in posttesting. Suggestions for continued computer education of diploma student nurses are provided.

The influx of nurses to the critical-care environment is continuous. In many workplaces, the nurses who are new to critical care are also newly graduated nurses. These new critical-care nurses and their critical-care nursing colleagues, who may have worked in critical care for many years, need to demonstrate expert judgment in order to optimize the potential for positive patient outcomes. The purpose of this study was to explore critical-care nurses' perceptions about critical thinking and expert nursing judgment. Using grounded theory research design, I collected data from 1 1 critical-care nurses through focus groups, an interview, and postparticipation questionnaires. I have articulated a Critical-thinking Modelfor Expert Nursing Judgment. The educational model is directly relevant to practicing critical-care nurses and nursing leaders who guide critical-care nursing practice. The Critical-thinking Modelfor Expert Nursing Judgment contributes to educational theory by objectifying the substantive topic of critical thinking and expert judgment. The model has broad applicability within the domain of education and specific applicability within the domain of nursing education.

Each year, the College of Nurses of Ontario (CNO) requires all registered nurses and registered practical nurses in Ontario to complete a Reflective Practice learning activity. In doing so, nurses are expected to perform a self- assessment, identify a practice problem or issue, create and implement a personal learning plan, and evaluate the learning and outcomes accomplished. The process and components of CNO's Reflective Practice program are very similar to an Action Learning activity. The purpose of this qualitative research was to explore the perceptions of 1 1 nurses who completed at least 1 Action Learning activity. Data analysis of their comments provided insight into their perceptions of the Action Learning experience, perceptions of the negative and positive characteristics of various activities within the Action Learning process, and perceptions of barriers or challenges within this experience. The author concluded that participants perceived their Action Learning activities to be a positive experience because the process focused on practice problems and issues, enhanced thinking about practice problems, and achieved practice-relevant outcomes. However, the results indicated that self-directed learning and journal writing were difficult activities for some participants, and some experienced negative emotional responses during reflection. The research concluded that barriers to implementation of Action Learning include a lack of understanding of the process and a perceived lack of support from employers.

A convenience sample of twenty registered nurses was recruited from two' general hospitals and two community college nursing schools. Kelly's (1955) Personal Construct Theory provided the theoretical framework to discover how nurses perceived themselves as educators. The nurses completed a self-administered Self-Perception Inventory (Soares, 1983) to determine their perception of self as nurse and ideal self as nurse. In an interview, each of the nurses constructed a rank-order repertory grid adapted from Kelly's (1955) Role Repertory Construct Test. Twelve constructs derived from the Self-Perception Inventory (Soares, 1983) were ranked according to a list of ten elements common to a teaching situation. Rank order correlations among the constructs were determined with Spearman's rho. Using a dependent samples t-test, significant differences were found between perceptions of current and ideal self for staff nurses. Significant differences were also found between nurse educators' perceptions of self and ideal self as nurse. No significant differences were determined in perceptions of self as nurse and ideal self as nurse between the staff nurse and nurse educator groups with an independent samples t-test. However, observations of single constructs revealed that although several constructs are shared between the groups in the perception of self in a teaching situation, both groups hold constructs that operate exclusively in their separate domains. The nature and strength of the relationships between the common and unique constructs are different for each group. Nurses I self-perceptions appear to be influenced by the historical development of nursing, role socialization during nursing education, social expectations and gender issues in the health care system.
