Are we Bridging the Divide in IWO Psychology?

This paper examines the knowledge transfer process within the profession of work and organisational psychology. In consonance with the theme of the 2011 congress, it considers the extent to which proposed ‘bridging mechanisms’ can provide useful vehicles for operationalising the pursuit of the dual goal of improving both the well-being of individuals and the effectiveness of work organizations. It considers the way in which the profession attempts to ground its concepts in a sound evidence base and then successfully mobilise this knowledge at the interface of research and practice. It does so by critically examining the scientist-practitioner model and the ways in which this model can be operationalised by practitioners and researchers. The criticism which is aimed at academics is that their research is irrelevant; it explores narrow concepts too often with student samples. Practitioners, on the other hand, are accused of too infrequently bringing scientific findings from the research literature to their practice. The problem has been cast in terms of both one of knowledge production and also knowledge transfer and is typified, at least in one direction – the impact of research upon practice, by what has in other professions, most notably medicine and more recently management, been called evidence-based practice. Denise Rousseau, in her 2005 presidential address to the American Academy of Management defined evidence-based management (EBM) as “translating principles based on best evidence into organizational practices” and there have been a number of attempts to invoke a similar model of evidence-based practice in the field of work and organisational psychology. In 2007 Anderson described the academic-practitioner divide as ‘natural’, suggesting the way forward was to focus on ‘bridging mechanisms’ describing six which had been proposed at the 1995 SIOP conference. What is the situation over decade later? To what extent have these bridges been built? This paper explores the nature and extent of these bridges by presenting case studies and findings from a UK survey of IWO psychologists

Finding solutions for complex systems: saving traction energy in rail

Complex optimisation problems, which are concerned with optimising a given aspect of a complex system, such as time or energy, are difficult to solve. Often a range of solutions exist, and the difficulty lies in determining which solutions to implement in which part of the system. Within this work, a novel method is developed that allows the solver to overcome the key challenges for these types of problems, which are: defining the system parts (subsystems); minimising model complexity; quantifying solution effectiveness; and identifying relationships between solutions and subsystems. The method is demonstrated through application to the problem of railway traction energy saving. Subsystems are defined using quantified network and service characteristics. For each subsystem, the trends between six key solutions and the key performance indicators are analysed using multivariate data analysis and visualisation techniques. The relationships between subsystems are then explored at system level. The analysis determines the suitable solutions for each type of railway, providing information for operators about which solutions to target. Based on the results, the implementation of permanent magnet motor technology is considered, illustrating that the method is a suitable tool for informing further studies

Students’ Perceptions of the Societal and Personal Implications of Education Regarding Concepts of Evolution

Evolutionary theory is a national learning priority in the United States. However, evolution is differentially taught and accepted by individuals across the nation depending on a variety of factors. Many studies have been conducted on academic populations and their acceptance and understanding or lack thereof of concepts of evolution. However, many of these studies were conducted on generalized populations. The University of Colorado at Boulder has a unique population of biology students with varying backgrounds, and we were curious as to how their perceptions of the impacts of teaching evolution might differ from other groups. In the research for this thesis, students from a population of introductory biology students and a population of an upper division evolution class were asked the question “If all individuals were required to learn evolution, how would it change the way society functioned?” Their responses were transcribed and coded using NVivo 11 software. Overall, students in both populations similarly reported positive implications of learning evolution in the cognitive, or knowledge-gain, domain. Students from both populations also related learning evolutionary theory to affective and behavioral gains. Responses from both populations were mostly positive, contrary to previous research. Students in the upper-division class also tended to address the concept of human evolution, whereas the general biology students did not cite human evolution in their responses

Cellular viability and the occurence and significance of chlorophyll allomers during phytoplankton turnover.

Phytoplankton can exist in the water column, whole but non-functional, and the percentage of these dead cells in highly variable. These dead cells can contain chlorophyll and contribute to ocean colour, and hence estimates of oceanic primary productivity. The aim of this project was to assess indicators of phytoplankton physiological state, focusing on the formation of chlorophyll a oxidation products (allomers) and a chlorophyll precursor. Initially, to establish an appropriate method for the identification and quantification of chlorophyll allomers, a method selection and optimisation study was carried out. This assessment revealed that chlorophyll was prone to oxidation during sample analysis. Instrumentation, sample manipulation, method duration and HPLC solvent composition were all contributors to sample oxidation. The application of a method by Zapata et al. (2000) was found to produce minimal and consistent chlorophyll oxidation and was applied in subsequent studies. During a culture study of the picoeukaryote Ostreococcus tauri (Prasinophyceae), two chlorophyll allomers were formed solely during viral-infection, and not during environmental limitation of growth. Allomers began to increase 24 hours post viral-infection (hpi), simultaneously with decreases in population density and Fv/Fm, and an increase in membrane permeability. During viral-infection allomers reached a maximum level 48 hpi, which was 10-fold higher than the maximum level of allomers formed during environmental limitation. Chlorophyll a allomers were measured over an annual cycle for the first time, at the Western Channel Observatory (UK). Allomer occurrence (relative to chl-a) was maximal during April with a total allomer to chl-a ratio of 0.093 in surface water. Peaks in allomers were associated with blooms of Phaeocystis spp., Guinardia delicatula, Chaetoceros socialis and Emiliania huxleyi and associations were dependent on the cause of the taxas’ declines. In situ allomer measurements were also taken during a research cruise in the central and southern North Sea, where the maximum ratio of allomers to chl-a (0.15) was measured at the Flamborough Front

Green Guide to Composites: an environmental profiling system for composite materials and products

Products made from composite materials can offer significant environmental benefits because of their characteristically low weight, good mechanical properties and excellent resistance to corrosion. For example, composites used in cars can reduce the overall weight of the car and so offer fuel savings through the lifetime of the vehicle. However, although the in-service environmental benefits of composites are known, there is far less understanding of the environmental and social implications associated with the manufacture of composite materials and products. Issues affecting the industry include health and safety, the emission of volatile organic compounds (VOCs), energy consumption and toxicity from manufacture. Alternative materials and technologies (such as closed mould processes, natural fibres and low-styrene resins) have been developed to address these problems, but to date there has still been confusion within the industry as to the detailed benefits of these alternatives. This guide has been created to enable the composites sector to understand the environmental and social impacts associated with composite production and assist with the decisions made about material and process choice. The materials and processes modelled are rated from A (good) through to E (poor). Twelve different environmental impacts are individually scored and totalled to give an overall environmental impact summary rating. Two social impact ratings are also given. When measuring environmental impact it is important to consider all the influences through the life of the product. This process is known as Life Cycle Assessment (LCA) and it has been used in this guide for environmental investigation. Because this guide concentrates on materials and manufacturing, as opposed to in-service performance, the impacts associated with products beyond the factory gate (the use, maintenance and disposal stages of the life cycle) have not been assessed. Within the system boundaries for the LCA, three typical product types have been chosen to reflect a range of different components commonly manufactured using composites: • A double curvature panel – this has a surface area of 1m2 with a panel stiffness equivalent to a 4mm thick chopped strand mat laminate. • A flat sandwich panel – measuring 1m x 8m with a 25mm thick core, having a panel bending stiffness equivalent to a sandwich panel with a 4mm thick chopped strand mat skin. • A complex moulded component – with a volume of 770cm3. Similarly, production processes and materials have been selected to provide a balance between systems that are commonly used across the majority of the composites industry and emerging materials with the potential to provide an environmental benefit. For this reason, materials such as hemp fibre and self-reinforced polypropylene have been included in the guide, but materials that are more specific to a single sector (eg aramid fibre) have not been included. Within each specific process there are still many processing variations (eg methods for mixing, curing and trimming) in addition to the material choice possibilities. To enable fair comparisons, a base case has been selected for each process. This is used throughout the guide to allow the merits of each process variation to be assessed
