Introduction

The issue of firm growth - how it is achieved and managed, and what consequences it has for different stakeholders - is both theoretically interesting and practically important. It is also an area of scholarly enquiry that has expanded very significantly since we started doing research on it in the 1980s and 1990s. In this volume we present and comment upon the most recent contributions we have made to this field of inquiry - separately, jointly and with various colleagues (who are included in the 'we/us article authors' used in the remainder of this introduction). While the chapters have been published before in various places, we think it valuable to gather them in one easily accessible place, which also allows space for our reflective commentary across the individual chapters. We hope readers will find the work a useful and worthwhile addition to the extant body of knowledge about firm growth. We also hope they will find that it- as its title suggests- brings new•/ perspectives on firm growth and its study, and that it can inspire future contributions by other researchers. This is important, because despite the growing volume of research on firm growth, many important questions still lack satisfactory answers. The current volume may be regarded as a follow-up of a previous collection where we- and Frederic Delmar- presented and commented on eight articles on (mostly small) firm growth that we had jointly or separately published up until that time (Davidsson et al., 2006). In that volume we organised the works under three broad themes: the conceptual and empirical complexity of the firm growth phenomenon; growth aspirations and motivations; and patterns and determinants of actual growth The current volume builds on and extends these themes. Only one of the chapters in the previous volume directly addressed the issue of drivers of actual growth. We add three more in this book, two of which expand on the (aspirations and motivations' theme by relating growth aspirations and motivations (or lack thereof) of the owner-manager to the actual growth achieved in the subsequent period.

Towards an integrative framework for future research on small firm growth

Our review has demonstrated that small firm growth is a complex phenomenon. The concept ‘growth’ denotes both a change in amount and the process by which that change is attained. Further, the growth can be achieved in different ways and with varying degrees of regularity, and it manifests itself along several different dimensions such as sales, employment, and accumulation of assets. This complexity has naturally led researchers to adopt different approaches to studying growth and to use different measures to assess it. Further, although our review shows that it can fruitfully be regarded as a growth issue, the research on small firms' internationalization has largely developed as a separate stream. Similarly, other relatively separate literatures have evolved, which effectively focus on different modes of growth although mostly without regarding the studies first and foremost as growth studies. This goes for topics such as mergers and acquisitions, diversification, and integration - research streams which have largely ignored the particularities of small firms and which in turn have been largely ignored among researchers focusing on small firm growth.

Panda diplomacy : The cutest part of China’s public diplomacy

Summary In late 2011 and early 2012, the People’s Republic of China drew on its most unique diplomatic tool: the giant panda. Although this phenomenon is widely covered by the global media, the practice of panda diplomacy is only barely discussed in diplomatic or international relations studies. This article uses the most recent revival of this diplomatic practice for a closer analysis and locates it as a special version of animal diplomacy within the frame of public diplomacy. It first argues that panda diplomacy is — besides all the efforts to promote and support animal conservation and biological research — a political undertaking, which is symbolically used by the Chinese government to win hearts and minds in selected foreign countries. Second, it highlights an important aspect of some Chinese public diplomacy initiatives, namely China’s ability to integrate international partners in its attempts to shape its global image.

Women as victims and offenders : incarcerated for murder in the Australian criminal justice system

This study was undertaken in an effort to contribute to the limited knowledge of women who commit murder. Women account for approximately 10% of the total Australian homicides and according to Mouzos (2000), 20% of these female perpetrated homicides result in murder convictions. In her extensive study of female homicide offending in England, Brookman (2005) asserts that nearly two thirds of the victims of women who kill are intimates, to include violent partners and their own children. The other third of the victims consist largely of acquaintances and to lesser degree strangers (Brookman, 2005). This study strives to introduce further knowledge regarding women convicted of murder; the smaller subgroup of female homicide offenders of which less is known. It is comprised of women who killed intimates and non-intimates to include acquaintances. The study engages the narratives of seven women, all of whom were convicted of murder and serving lengthy sentences at the Dame Phyllis Frost Centre, a medium and maximum security prison that is located on the outskirts of Melbourne, Australia. The seven women fall largely outside of the characteristics of female homicide offenders as revealed in the studies from Australia’s National Homicide Monitoring Program (NHMP, 2007), from Canada by Hoffmann, Lavigne, and Dickie (1998) and research from the United States by Scott and Davies (2002). In this study there were no Indigenous women represented. Only one of the women had a previous criminal charge. The women were older on average than the prevailing demographics from western nations. Two of the women had substance abuse and co-occurring mental illness, which reflects a significant lower rate than the literature suggests. This study expands the current understanding of the phenomenon of women who murder. It communicates the narratives of seven women charged and convicted of murder as they attempt to understand their lives and identities. It moves the dialogue beyond the preponderance of feminist criminological research that examines motive and the relationship the woman has with her victim to the social discourses which dominate in her identity formation. This research found that in their attempt to create a favourable identity the women needed to engage with the master script of normative femininity through the feminisation of victimisation, motherhood and domesticity.

Speaking truth to power : sexism, outrage and the public consciousness

Alan Jones's now infamous comment that women are destroying the joint' sparked a flurry of observations and interpretations in the national and international media and in the blogosphere about the motivations and meanings of such a statement. The overriding tone of this commentary was outrage - how dare an influential figure like Jones state with such blatant and provocative hostility that women are at best unsuitable for leadership and at worst, damaging our public and private institutions? The answers, as we have seen, are likely to be complex, but an alternative question could also be posed. Why the outrage? Public male figures have, throughout history, made derogatory, demeaning and sexist remarks about women, and the material effects of gender inequality continue to be felt- consider the gender pay gap and glass ceiling phenomenon for starters. So why did this particular comment ignite such widespread indignation and anger?

Binocular rivalry and visuospatial ability in individuals with schizophrenia

Visual abnormalities, both at the sensory input and the higher interpretive levels, have been associated with many of the symptoms of schizophrenia. Individuals with schizophrenia typically experience distortions of sensory perception, resulting in perceptual hallucinations and delusions that are related to the observed visual deficits. Disorganised speech, thinking and behaviour are commonly experienced by sufferers of the disorder, and have also been attributed to perceptual disturbances associated with anomalies in visual processing. Compounding these issues are marked deficits in cognitive functioning that are observed in approximately 80% of those with schizophrenia. Cognitive impairments associated with schizophrenia include: difficulty with concentration and memory (i.e. working, visual and verbal), an impaired ability to process complex information, response inhibition and deficits in speed of processing, visual and verbal learning. Deficits in sustained attention or vigilance, poor executive functioning such as poor reasoning, problem solving, and social cognition, are all influenced by impaired visual processing. These symptoms impact on the internal perceptual world of those with schizophrenia, and hamper their ability to navigate their external environment. Visual processing abnormalities in schizophrenia are likely to worsen personal, social and occupational functioning. Binocular rivalry provides a unique opportunity to investigate the processes involved in visual awareness and visual perception. Binocular rivalry is the alternation of perceptual images that occurs when conflicting visual stimuli are presented to each eye in the same retinal location. The observer perceives the opposing images in an alternating fashion, despite the sensory input to each eye remaining constant. Binocular rivalry tasks have been developed to investigate specific parts of the visual system. The research presented in this Thesis provides an explorative investigation into binocular rivalry in schizophrenia, using the method of Pettigrew and Miller (1998) and comparing individuals with schizophrenia to healthy controls. This method allows manipulations to the spatial and temporal frequency, luminance contrast and chromaticity of the visual stimuli. Manipulations to the rival stimuli affect the rate of binocular rivalry alternations and the time spent perceiving each image (dominance duration). Binocular rivalry rate and dominance durations provide useful measures to investigate aspects of visual neural processing that lead to the perceptual disturbances and cognitive dysfunction attributed to schizophrenia. However, despite this promise the binocular rivalry phenomenon has not been extensively explored in schizophrenia to date. Following a review of the literature, the research in this Thesis examined individual variation in binocular rivalry. The initial study (Chapter 2) explored the effect of systematically altering the properties of the stimuli (i.e. spatial and temporal frequency, luminance contrast and chromaticity) on binocular rivalry rate and dominance durations in healthy individuals (n=20). The findings showed that altering the stimuli with respect to temporal frequency and luminance contrast significantly affected rate. This is significant as processing of temporal frequency and luminance contrast have consistently been demonstrated to be abnormal in schizophrenia. The current research then explored binocular rivalry in schizophrenia. The primary research question was, "Are binocular rivalry rates and dominance durations recorded in participants with schizophrenia different to those of the controls?" In this second study binocular rivalry data that were collected using low- and highstrength binocular rivalry were compared to alternations recorded during a monocular rivalry task, the Necker Cube task to replicate and advance the work of Miller et al., (2003). Participants with schizophrenia (n=20) recorded fewer alternations (i.e. slower alternation rates) than control participants (n=20) on both binocular rivalry tasks, however no difference was observed between the groups on the Necker cube task. Magnocellular and parvocellular visual pathways, thought to be abnormal in schizophrenia, were also investigated in binocular rivalry. The binocular rivalry stimuli used in this third study (Chapter 4) were altered to bias the task for one of these two pathways. Participants with schizophrenia recorded slower binocular rivalry rates than controls in both binocular rivalry tasks. Using a ‘within subject design’, binocular rivalry data were compared to data collected from a backwardmasking task widely accepted to bias both these pathways. Based on these data, a model of binocular rivalry, based on the magnocellular and parvocellular pathways that contribute to the dorsal and ventral visual streams, was developed. Binocular rivalry rates were compared with performance on the Benton’s Judgment of Line Orientation task, in individuals with schizophrenia compared to healthy controls (Chapter 5). The Benton’s Judgment of Line Orientation task is widely accepted to be processed within the right cerebral hemisphere, making it an appropriate task to investigate the role of the cerebral hemispheres in binocular rivalry, and to investigate the inter-hemispheric switching hypothesis of binocular rivalry proposed by Pettigrew and Miller (1998, 2003). The data were suggestive of intra-hemispheric rather than an inter-hemispheric visual processing in binocular rivalry. Neurotransmitter involvement in binocular rivalry, backward masking and Judgment of Line Orientation in schizophrenia were investigated using a genetic indicator of dopamine receptor distribution and functioning; the presence of the Taq1 allele of the dopamine D2 receptor (DRD2) receptor gene. This final study (Chapter 6) explored whether the presence of the Taq1 allele of the DRD2 receptor gene, and thus, by inference the distribution of dopamine receptors and dopamine function, accounted for the large individual variation in binocular rivalry. The presence of the Taq1 allele was associated with slower binocular rivalry rates or poorer performance in the backward masking and Judgment of Line Orientation tasks seen in the group with schizophrenia. This Thesis has contributed to what is known about binocular rivalry in schizophrenia. Consistently slower binocular rivalry rates were observed in participants with schizophrenia, indicating abnormally-slow visual processing in this group. These data support previous studies reporting visual processing abnormalities in schizophrenia and suggest that a slow binocular rivalry rate is not a feature specific to bipolar disorder, but may be a feature of disorders with psychotic features generally. The contributions of the magnocellular or dorsal pathways and parvocellular or ventral pathways to binocular rivalry, and therefore to perceptual awareness, were investigated. The data presented supported the view that the magnocellular system initiates perceptual awareness of an image and the parvocellular system maintains the perception of the image, making it available to higher level processing occurring within the cortical hemispheres. Abnormal magnocellular and parvocellular processing may both contribute to perceptual disturbances that ultimately contribute to the cognitive dysfunction associated with schizophrenia. An alternative model of binocular rivalry based on these observations was proposed.

The momentum effect in competitions : field evidence from tennis matches

It is often suggested that there is a psychological advantage to be leading in a competition. It is, however, hard to identify such an effect econometrically. Using a Regression Discontinuity Design over a large dataset of tennis matches (N=634,095) the present paper exploits the randomised variation in first set results that occurs when the first set is decided by a close tie break (N=72,294). I find that winning the first set has a significant and strong effect on the result of the second set. A player who wins a close first set tie break will, on average, win one game more in the second set. I discuss the likely economic and psychological explanations of this phenomenon.

Gravity-driven fingering simulations for a thin liquid film flowing down the outside of a vertical cylinder

A numerical study is presented to examine the fingering instability of a gravity-driven thin liquid film flowing down the outer wall of a vertical cylinder. The lubrication approximation is employed to derive an evolution equation for the height of the film, which is dependent on a single parameter, the dimensionless cylinder radius. This equation is identified as a special case of that which describes thin film flow down an inclined plane. Fully three-dimensional simulations of the film depict a fingering pattern at the advancing contact line. We find the number of fingers observed in our simulations to be in excellent agreement with experimental observations and a linear stability analysis reported recently by Smolka & SeGall (Phys Fluids 23, 092103 (2011)). As the radius of the cylinder decreases, the modes of perturbation have an increased growth rate, thus increasing cylinder curvature partially acts to encourage the contact line instability. In direct competition with this behaviour, a decrease in cylinder radius means that fewer fingers are able to form around the circumference of the cylinder. Indeed, for a sufficiently small radius, a transition is observed, at which point the contact line is stable to transverse perturbations of all wavenumbers. In this regime, free surface instabilities lead to the development of wave patterns in the axial direction, and the flow features become perfectly analogous to the two-dimensional flow of a thin film down an inverted plane as studied by Lin & Kondic (Phys Fluids 22, 052105 (2010)). Finally, we simulate the flow of a single drop down the outside of the cylinder. Our results show that for drops with low volume, the cylinder curvature has the effect of increasing drop speed and hence promoting the phenomenon of pearling. On the other hand, drops with much larger volume evolve to form single long rivulets with a similar shape to a finger formed in the aforementioned simulations.

Early years research

Early years research is increasingly concerned with the everyday lives of young children and adults in the cut-and-thrust of early years contexts. It is concerned with what happens in situ, that is, in the everyday lives of those within the context. It is concerned with understanding young children and adults in the contexts of their lives; but it goes beyond understanding to transforming their contexts such that children and adults have the best possible chances, now and in the future. The dual focus of understanding and transforming makes early years research a powerful force for change. This chapter explores key theoretical underpinnings of early years research and presents key aspects of conducting research in ethical and sustainable ways. Early years research, here, refers to research conducted by early years practitioner researchers in the context of their own setting. It may involve research around their own practice and/or research around a particular issue or phenomenon of importance in their setting – the focal point may be children, families or practitioners or combinations thereof. The research may be a seamless part of the daily routine of the setting or may be a discreet project, clearly delineated with a timeframe for commencement and conclusion. The research may be used for ongoing reflection and planning with the setting and/or for dissemination in research reports or scholarly publications.

Conceptual model linking knowledge management with organisational performance

Better management of knowledge assets has the potential to improve business processes and increase productivity. This fact has led to considerable interest in recent years in the knowledge management (KM) phenomenon, and in the main dimensions that can impact on its application in construction. However, a lack of a systematic way of assessing KM initia-tives’ contribution towards achieving organisational business objectives is evident. This paper describes the first stage of a research project intended to develop, and empirically test, a KM input-process-output framework comprising unique and well-defined theoretical constructs representing the KM process and its internal and external determinants in the context of con-struction. The paper presents the underlying principles used in operationally defining each construct through the use of extant KM literature. The KM process itself is explicitly mod-elled via a number of clearly articulated phases that ultimately lead to knowledge utilisation and capitalisation, which in turn adds value or otherwise to meeting defined business objec-tives. The main objective of the model is to reduce the impact of subjectivity in assessing the contribution made by KM practices and initiatives toward achieving performance improvements.

A finite element model of seat cushion indentation with a soft tissue human occupant model

Effective digital human model (DHM) simulation of automotive driver packaging ergonomics, safety and comfort depends on accurate modelling of occupant posture, which is strongly related to the mechanical interaction between human body soft tissue and flexible seat components. This paper presents a finite-element study simulating the deflection of seat cushion foam and supportive seat structures, as well as human buttock and thigh soft tissue when seated. The three-dimensional data used for modelling thigh and buttock geometry were taken on one 95th percentile male subject, representing the bivariate percentiles of the combined hip breadth (seated) and buttock-to-knee length distributions of a selected Australian and US population. A thigh-buttock surface shell based on this data was generated for the analytic model. A 6mm neoprene layer was offset from the shell to account for the compression of body tissue expected through sitting in a seat. The thigh-buttock model is therefore made of two layers, covering thin to moderate thigh and buttock proportions, but not more fleshy sizes. To replicate the effects of skin and fat, the neoprene rubber layer was modelled as a hyperelastic material with viscoelastic behaviour in a Neo-Hookean material model. Finite element (FE) analysis was performed in ANSYS V13 WB (Canonsburg, USA). It is hypothesized that the presented FE simulation delivers a valid result, compared to a standard SAE physical test and the real phenomenon of human-seat indentation. The analytical model is based on the CAD assembly of a Ford Territory seat. The optimized seat frame, suspension and foam pad CAD data were transformed and meshed into FE models and indented by the two layer, soft surface human FE model. Converging results with the least computational effort were achieved for a bonded connection between cushion and seat base as well as cushion and suspension, no separation between neoprene and indenter shell and a frictional connection between cushion pad and neoprene. The result is compared to a previous simulation of an indentation with a hard shell human finite-element model of equal geometry, and to the physical indentation result, which is approached with very high fidelity. We conclude that (a) SAE composite buttock form indentation of a suspended seat cushion can be validly simulated in a FE model of merely similar geometry, but using a two-layer hard/soft structure. (b) Human-seat indentation of a suspended seat cushion can be validly simulated with a simplified human buttock-thigh model for a selected anthropomorphism.

Charge carrier exchange at chemically modified graphene edges: A density functional theory study

Heteroatom doping on the edge of graphene may serve as an effective way to tune chemical activity of carbon-based electrodes with respect to charge carrier transfer in an aqueous environment. In a step towards developing mechanistic understanding of this phenomenon, we explore herein mechanisms of proton transfer from aqueous solution to pristine and doped graphene edges utilizing density functional theory. Atomic B-, N-, and O- doped edges as well as the native graphene are examined, displaying varying proton affinities and effective interaction ranges with the H3O+ charge carrier. Our study shows that the doped edges characterized by more dispersive orbitals, namely boron and nitrogen, demonstrate more energetically favourable charge carrier exchange compared with oxygen, which features more localized orbitals. Extended calculations are carried out to examine proton transfer from the hydronium ion in the presence of explicit water, with results indicating that the basic mechanistic features of the simpler model are unchanged.

Getting in the door : the voluntary provision of accessible housing in Australia

This paper outlines the methodology used in a PhD qualitative research study on the agency of the housing industry in Australia in the provision of accessible housing. Previous studies have identified the need for an increased supply of accessible housing to optimise the inclusion and participation of all people, yet the demand for accessible housing by new home buyers is minimal and voluntary strategies to increase supply have typically failed. In 2010, housing industry leaders agreed to adopt a national voluntary access guideline for housing (Livable Housing Design) and a strategy to provide minimum access features in all new housing by 2020. This study explores the “escaped” phenomenon; how individual agents within the housing industry respond to such initiatives. As the paper is written mid-study it uses a preliminary theme in the findings, that is, minimal demand, to illustrate the methodology of the research.

A Systematic review of a statistical vacuum circuit breaker model for condition monitoring

Vacuum circuit breaker (VCB) overvoltage failure and its catastrophic failures during shunt reactor switching have been analyzed through computer simulations for multiple reignitions with a statistical VCB model found in the literature. However, a systematic review (SR) that is related to the multiple reignitions with a statistical VCB model does not yet exist. Therefore, this paper aims to analyze and explore the multiple reignitions with a statistical VCB model. It examines the salient points, research gaps and limitations of the multiple reignition phenomenon to assist with future investigations following the SR search. Based on the SR results, seven issues and two approaches to enhance the current statistical VCB model are identified. These results will be useful as an input to improve the computer modeling accuracy as well as the development of a reignition switch model with point-on-wave controlled switching for condition monitoring
