Mapping intermedia news flows : topical discussions in the Australian and French political blogospheres

The growth of technologies and tools branded as =new media‘ or =Web 2.0‘ has sparked much discussion about the internet and its place in all facets of social life. Such debate includes the potential for blogs and citizen journalism projects to replace or alter journalism and mainstream media practices. However, while the journalism-blog dynamic has attracted the most attention, the actual work of political bloggers, the roles they play in the mediasphere and the resources they use, has been comparatively ignored. This project will look at political blogging in Australia and France - sites commenting on or promoting political events and ideas, and run by citizens, politicians, and journalists alike. In doing so, the structure of networks formed by bloggers and the nature of communication within political blogospheres will be examined. Previous studies of political blogging around the world have focussed on individual nations, finding that in some cases the networks are divided between different political ideologies. By comparing two countries with different political representation (two-party dominated system vs. a wider political spectrum), this study will determine the structure of these political blogospheres, and correlate these structures with the political environment in which they are situated. The thesis adapts concepts from communication and media theories, including framing, agenda setting, and opinion leaders, to examine the work of political bloggers and their place within the mediasphere. As well as developing a hybrid theoretical base for research into blogs and other online communication, the project outlines new methodologies for carrying out studies of online activity through the analysis of several topical networks within the wider activity collected for this project. The project draws on hyperlink and textual data collected from a sample of Australian and French blogs between January and August 2009. From this data, the thesis provides an overview of =everyday‘ political blogging, showing posting patterns over several months of activity, away from national elections and their associated campaigns. However, while other work in this field has looked solely at cumulative networks, treating collected data as a static network, this project will also look at specific cases to see how the blogospheres change with time and topics of discussion. Three case studies are used within the thesis to examine how blogs cover politics, featuring an international political event (the Obama inauguration), and local political topics (the opposition to the =Création et Internet‘, or HADOPI, law in France, the =Utegate‘ scandal in Australia). By using a mixture of qualitative and quantitative methods, the study analyses data collected from a population of sites from both countries, looking at their linking patterns, relationship with mainstream media, and topics of interest. This project will subsequently help to further develop methodologies in this field and provide new and detailed information on both online networks and internet-based political communication in Australia and France.

Between a rock and a hard place : what do public sector leaders learn from the past as they lead into the future

The purpose of this paper is to bring leadership context into sharper focus and to suggest there are strong constraints on public leaders’ discretion to lead in ways consistent with NPM or NPL. Much of the existing public leadership research focuses on the individual leader and tends to give little attention to the influence of context. This lack of focus on leader context adversely affects our ability to build public leadership capacity. We draw on prior research to establish that (1) there are strong contextual constraints on public leaders’ capacity to lead in ways consistent with NPL, (2) public leaders are subject to contradictory messages and for the most part these contradictions are unacknowledged and unresolved, the impact of which is confusion and informal power-politics, (3) the task of leader transition from traditional leadership to new public leadership is very much underestimated and requires a new way to think about leadership development. On the basis of this analysis, we argue that public leaders find themselves between a rock and a hard place.

Can a childcare practicum encourage degree qualified staff to enter the childcare workforce?

Concern to ensure that all children have access to high quality educational experiences in the early years of life has instigated moves to increase qualifications of staff in the childcare workforce, in particular to increase the number of degree qualified teachers. However existing data suggest that work in the childcare sector is viewed less favourably by those undertaking early childhood education degrees. For most, childcare is not a preferred place of employment. This study asked whether a practicum in a childcare setting would improve attitudes to childcare and willingness to consider working in childcare settings. In a study of a cohort of Bachelor of Education (Early Childhood) students, measures of attitudes to childcare and willingness to work in childcare were taken before and after practicum. Additionally students provided accounts of their practicum experiences. Results indicate a trend in which there was a group increase in positive attitudes and willingness to consider work in childcare but considerable individual differences influenced by the quality of the practicum experience. The relationship with, and model provided by, centre directors and the group leader in the practicum class was identified as key influencing factors. Results are discussed in term of models of pedagogical leadership.

Conflict and seduction in the public sphere

In a critical but sympathetic reading of Habermas’s work (1984, 1987a, 1987b, 2003), Luke Goode (2005) recently sought to rework his theory of deliberative democracy in an age of mediated and increasingly digital public spheres. Taking a different approach, Alan McKee (2005) challenged the culture- and class-bound strictures of Habermasian rationalism, instead pursuing a more radically pluralist account of postmodern public spheres. The editors of this special section of Media, Culture & Society invited us to discuss our differing approaches to the public sphere. Goode holds that the institutional bases of contemporary public spheres (political parties, educational institutions or public media) remain of critical importance, albeit in the context of a kaleidoscopic array of unofficial and informal micro-publics, both localized and de-territorialized. In contrast, McKee sustains a ‘hermeneutics of suspicion’ toward the official, hegemonic institutions of the public sphere since they tend to exclude and delegitimize discourses and practices that challenge their polite middle-class norms. McKee’s recent research has focused on sexual cultures, particularly among youth (McKee, 2011). Goode’s recent work has examined new social media spaces, particularly in relation to news and public debate (e.g. Goode, 2009; Goode et al., 2011). Consequently, our discussion turned to a domain which links our interests: after Goode discussed some of his recent research on (in)civility on YouTube as a new media public sphere, McKee challenged him to consider the case of pornographic websites modelled on social media sites.1 He identifies a greater degree of ‘civility’ in these pornographic sibling sites than on YouTube, requiring careful consideration of what constitutes a ‘public sphere’ in contemporary digital culture. Such sites represent an environment that shatters the opposition of public and private interest, affording public engagement on matters of the body, of intimacy, of gender politics, of pleasure and desire – said by many critics to be ruled out of court in Habermasian theory. Such environments also trouble traditional binaries between the cognitive and the affective, and between the performative and the deliberative. In what follows we explore the differences between our approaches in the form of a dialogue. As is often the case, our approaches seemed less at odds after engaging in conversation than may have initially appeared. But important differences of emphasis remain.

The changing role of actors in the participatory project for rural craftspeople

This paper examines the role of actors in a participatory project, a case study of the glass-bead traditional craft industry in rural Indonesia. The project aimed to unite and empower rural craftspeople with regard to their unique potential. The problems of empowering rural craftspeople were complicated, due to the interrelated aspect of rural community life, cultural and educational backgrounds, as well as the local political situation. However, through a comprehensive understanding of the community prior to the project and by maintaining the communication, craftspeople were engaged actively in the project by promoting the craft industry to local buyers. The researcher, other facilitators and the community leader gave supportive roles at the middle and the end stage of the project.

Acting and knowing in temporary and project-based organizing : turning from the practice world to a liberation praxeology?

The purpose of this article is to offer a critical discussion about the “practice” lens and its weaknesses in addressing acting and knowledge & competence development in the context of temporary and project-based organizing. I demonstrate that “practice turn” and “phronetic proposal” are dual and opposite perspectives within the “practice” world, none of them being fully relevant to grasp project organizing and that each of them maintain the opposition between the “observer” and the “natives “of the practices. I suggest an alternate style of reasoning in order to address the dissatisfaction in face of problems, antinomies, perplexities and contradictions generated by the dichotomous thinking: a liberation praxeology rooted in Aristotle philosophy aiming, through praxis & phronesis and practical acquired experience & perfecting actualization, at reconciling facts & values and means & ends, and Ethics & Politics in the quest for human happiness and social good through project organizing.

Investigating the impact of a leadership development program for nurse unit managers on the satisfaction of nursing staff

Background and significance: Nurses' job dissatisfaction is associated with negative nursing and patient outcomes. One of the most powerful reasons for nurses to stay in an organisation is satisfaction with leadership. However, nurses are frequently promoted to leadership positions without appropriate preparation for the role. Although a number of leadership programs have been described, none have been tested for effectiveness, using a randomised control trial methodology. Aims: The aims of this research were to develop an evidence based leadership program and to test its effectiveness on nurse unit managers' (NUMs') and nursing staff's (NS's) job satisfaction, and on the leader behaviour scores of nurse unit managers. Methods: First, the study used a comprehensive literature review to examine the evidence on job satisfaction, leadership and front-line manager competencies. From this evidence a summary of leadership practices was developed to construct a two component leadership model. The components of this model were then combined with the evidence distilled from previous leadership development programs to develop a Leadership Development Program (LDP). This evidence integrated the program's design, its contents, teaching strategies and learning environment. Central to the LDP were the evidence-based leadership practices associated with increasing nurses' job satisfaction. A randomised controlled trial (RCT) design was employed for this research to test the effectiveness of the LDP. A RCT is one of the most powerful tools of research and the use of this method makes this study unique, as a RCT has never been used previously to evaluate any leadership program for front-line nurse managers. Thirty-nine consenting nurse unit managers from a large tertiary hospital were randomly allocated to receive either the leadership program or only the program's written information about leadership. Demographic baseline data were collected from participants in the NUM groups and the nursing staff who reported to them. Validated questionnaires measuring job satisfaction and leader behaviours were administered at baseline, at three months after the commencement of the intervention and at six months after the commencement of the intervention, to the nurse unit managers and to the NS. Independent and paired t-tests were used to analyse continuous outcome variables and Chi Square tests were used for categorical data. Results: The study found that the nurse unit managers' overall job satisfaction score was higher at 3-months (p = 0.016) and at 6-months p = 0.027) post commencement of the intervention in the intervention group compared with the control group. Similarly, at 3-months testing, mean scores in the intervention group were higher in five of the six "positive" sub-categories of the leader behaviour scale when compared to the control group. There was a significant difference in one sub-category; effectiveness, p = 0.015. No differences were observed in leadership behaviour scores between groups by 6-months post commencement of the intervention. Over time, at three month and six month testing there were significant increases in four transformational leader behaviour scores and in one positive transactional leader behaviour scores in the intervention group. Over time at 3-month testing, there were significant increases in the three leader behaviour outcome scores, however at 6-months testing; only one of these leader behaviour outcome scores remained significantly increased. Job satisfaction scores were not significantly increased between the NS groups at three months and at six months post commencement of the intervention. However, over time within the intervention group at 6-month testing there was a significant increase in job satisfaction scores of NS. There were no significant increases in NUM leader behaviour scores in the intervention group, as rated by the nursing staff who reported to them. Over time, at 3-month testing, NS rated nurse unit managers' leader behaviour scores significantly lower in two leader behaviours and two leader behaviour outcome scores. At 6-month testing, over time, one leader behaviour score was rated significantly lower and the nontransactional leader behaviour was rated significantly higher. Discussion: The study represents the first attempt to test the effectiveness of a leadership development program (LDP) for nurse unit managers using a RCT. The program's design, contents, teaching strategies and learning environment were based on a summary of the literature. The overall improvement in role satisfaction was sustained for at least 6-months post intervention. The study's results may reflect the program's evidence-based approach to developing the LDP, which increased the nurse unit managers' confidence in their role and thereby their job satisfaction. Two other factors possibly contributed to nurse unit managers' increased job satisfaction scores. These are: the program's teaching strategies, which included the involvement of the executive nursing team of the hospital, and the fact that the LDP provided recognition of the importance of the NUM role within the hospital. Consequently, participating in the program may have led to nurse unit managers feeling valued and rewarded for their service; hence more satisfied. Leadership behaviours remaining unchanged between groups at the 6 months data collection time may relate to the LDP needing to be conducted for a longer time period. This is suggested because within the intervention group, over time, at 3 and 6 months there were significant increases in self-reported leader behaviours. The lack of significant changes in leader behaviour scores between groups may equally signify that leader behaviours require different interventions to achieve change. Nursing staff results suggest that the LDP's design needs to consider involving NS in the program's aims and progress from the outset. It is also possible that by including regular feedback from NS to the nurse unit managers during the LDP that NS's job satisfaction and their perception of nurse unit managers' leader behaviours may alter. Conclusion/Implications: This study highlights the value of providing an evidence-based leadership program to nurse unit managers to increase their job satisfaction. The evidence based leadership program increased job satisfaction but its effect on leadership behaviour was only seen over time. Further research is required to test interventions which attempt to change leader behaviours. Also further research on NS' job satisfaction is required to test the indirect effects of LDP on NS whose nurse unit managers participate in LDPs.

Profile of a narcissistic leader : coffee’s for closers only

Purpose In the past, leadership scholars have tended to focus on leadership as a force for good and productivity (Ashworth, 1994; Higgs, 2009; Padilla, Hogan, & Kaiser, 2007). However, recently attention has been given to the ‘dark side’ of leadership (see Higgs, 2009; Judge, Piccolo, & Kosalka, 2009). The aim of this chapter is to explore dark leadership from the perspective of the narcissistic leader using a fictional character from a popular film. Methodology/approach Using the Diagnostic and Statistical Manual of Mental Disorders, 4th edition, 1994 (DSM-IV) (American Psychiatric Association, 2000) as an operational definition of narcissistic personality disorder we explore the psychology of the narcissistic leader through a fictional character study in a popular film. Findings We have created a psychological profile of a narcissistic leader which identifies specific behavioural characteristics within a toxic organizational culture. Social implications This study has implications for employees within any organizational culture. It is significant because it can illustrate how dark leadership can impact negatively within organizations. Originality/value The use of actual living persons on which to base case study material in the study of dark leadership is problematic and constrained by ethical issues. However, the use of characters in fiction, such as contemporary film and drama, represents an excellent source of case study material. Given that little empirical works exists on narcissistic leaders and leadership, the chapter adds originality and value to the field.

Leader vision and diffusion of HR policy during change

Purpose – This paper utilizes diffusion of innovation theory in order to investigate and understand the relationships between HR policies on employee change-related outcomes. In addition, the aim is to explore the role of leader vision at different hierarchical levels in the organization in terms of the relationship of HR policy with employee change-related outcomes. Design/methodology/approach – This quantitative study was conducted in one large Australian government department undergoing major restructuring and cultural change. Data from 624 employees were analyzed in relation to knowledge of HR policies (awareness and clarity), leader vision (organizational and divisional), and change-related outcomes. Findings –Policy knowledge (awareness and clarity) does not have a direct impact on employee change-related outcomes. It is the implementation of policies through the divisional leader that begins to enable favorable employee outcomes. Research limitations/implications – Future research should employ a longitudinal design to investigate relationships over time, and also examine the importance of communication medium and individual preferences in relation to leader vision. Originality/value - This research extends the application of diffusion of innovation theory and leader vision theory to investigate the relationship between HR policy, leader vision, and employees’ change-related outcomes.

Managing peripheral intravenous devices in the adults' general surgical setting: a best practice implementation report

AIM The aim of this evidence-based practice (EBP) project was to promote adherence to the current best practice in monitoring and optimal replacement of peripheral intravenous device (PIVD). METHODS This EBP project took place in a 30-bed acute general surgical ward. Twenty in-patients with PIVD in situ for 4 days or more were recruited. There were five stages in the project: identification of EBP topic, criteria, sample and setting; baseline; dissemination of baseline audit results and identification of best practice barriers; identification of barriers to EBP and implementation of strategies promoting EBP; and postimplementation audit. RESULTS There were eight criteria in this project. The first audit showed moderate compliance in PIVD monitoring and optimal replacement. The project identified three barriers: lack of awareness of the current evidence-based guidelines, hospital policy not being aligned with current guidelines and no standard form of documentation. In order to overcome these barriers the following strategies were used: audit and feedback, interactive educational meetings, reminders and hospital policy change. The second audit showed minor improvements in each criterion. Compliance with documentation remained a challenge, possibly because of the lack of standardised documentation. DISCUSSION Although the project did not render us the results we aimed for, it was successful because it highlighted the current EBP in PIVD management. The major challenges of the project were time and the lack of opinion leaders in our project team. We felt that more time was needed to adapt to the practice change and standardised documentation could not be developed in such a short time period. Further, the role of the opinion leader proved to be vital in this project. We felt that had we recruited more than one opinion leader, the results would have been different.

Hyperexpression of chicken riboflavin carrier protein: Antibodies to the recombinant protein curtail pregnancy in rodents

Chicken riboflavin carrier protein (RCP) is a phosphoglycoprotein present in the egg white and yolk of egg-laying animals and in the sera of laying hens and of estrogenized chicks. The RCP cDNA, encoding a protein of predictedMr27,000, has been cloned into a T7 polymerase-driven vector, and high-level expression was observed on induction with IPTG inEscherichia coli.The protein was largely localized in inclusion bodies when expressed at 37°C but was present in the cytosolic fraction when induced at 22°C. At 37°C, two major bands were detected in whole-cell lysates of the strain expressing the protein. N-terminal sequence analysis indicated that the two proteins represented translated products with and without the pelB leader sequence encoded in the pET20b vector, but both included an additional 10 amino acids generated during cloning procedures. The inclusion body obtained at 37°C, on extraction with detergent, led to preferential solubilization of the protein without the pelB signal sequence. The solubilized recombinant RCP was recognized by polyclonal antisera to native RCP but radioimmunoassay revealed quantitative differences in the epitopes exhibited by the recombinant protein. Thus, sequence-specific monoclonal antibodies to chicken RCP also cross-reacted with the recombinant protein with almost equal efficiency, but antibodies which recognize conformation-dependent epitopes showed relatively reduced cross-reactivity with the recombinant protein. Polyclonal antibodies to recombinant RCP were able to recognize both the native and the denatured RCP. Administration of recombinant RCP antisera to pregnant mice led to embryonic resorption leading to early pregnancy termination. These findings reveal that the recombinant protein will be useful for investigations related to the mechanism of pregnancy termination on immunoneutralization of RCP in mammals, as well as in unraveling folding properties of RCP in terms of its ligand binding and antigenetic determinants exposed at its surface.

Common past, divided memories: historical memory of the Polish minority members in Lithuania

The Master’s thesis examines historical memory of the Polish minority members in Lithuania with regard to how their interpretation of the common Polish-Lithuanian history reiterates or differs from the official Polish and Lithuanian narratives conveyed by the school textbooks. History teaching in high schools carries a crucial state-supported role of “identity building policies” – it maintains a national narrative of memory, which might be exclusive to minorities and their peculiar understanding of history. Lithuanians Poles, in this regard, represent a national minority, which is exposed to two conflicting national narratives of the common past – Polish and Lithuanian. As members of the Polish nation, their understanding of the common Polish-Lithuanian history is conditioned by the Polish historical narrative, acquired as part of the collective memory of the family and/or different minority organizations. On the other hand, they encounter Lithuanian historical narrative of the Polish-Lithuanian past throughout the secondary school history education, where the curriculum, even if taught in Polish, largely represents the Lithuanian point of view. The concept of collective memory is utilized to refer to collective representations of national memory (i.e. publicly articulated narratives and images of collective past in history textbooks) as well as to socially framed individual memories (i.e. historical memory of minority members, where individual remembering is framed by the social context of their identity). The thesis compares the official national historical narratives in Lithuania and Poland, as conveyed by the Polish and Lithuanian history textbooks. The consequent analysis of qualitative interviews with the Polish minority members in Lithuania offers insights into historical memory of Lithuanian Poles and its relation to the official Polish and Lithuanian national narratives of the common past. Qualitative content analysis is applied in both parts of the analysis. The narratives which emerge from the interview data could be broadly grouped into two segments. First, a more pronounced view on the past combines the following elements: i) emphasis on the value of multicultural and diverse past of Lithuania, ii) contestation of “Lithuanocentricity” of the Lithuanian narrative and iii) rejection of the term “occupation”, based on the cultural presuppositions – the dominant position of Polish culture and language in the Vilnius region, symbolic belonging and “Lithuanianness” of the local Poles. While the opposition to the term of “occupation” is in accord with the official Polish narrative conveyed by the textbooks, the former two elements do not neatly adhere to either Polish or Lithuanian textbook narratives. They should rather be considered as an expression of claims for inclusion of plural pasts into Lithuanian collective memory and hence as claims for symbolic enfranchisement into the Lithuanian “imagined community”. The second strand of views, on the other hand, does not exclude assertions about the historically dominant position of Polish culture in Lithuania, but at the same time places more emphasis on the political and historical continuity of the Lithuanian state and highlights a long-standing symbolic connectedness of Vilnius and Lithuania, thus, striking a middle way between the Polish and Lithuanian interpretations of the past.

A Physical Model for Inception and Propagation of Upward Lightning Leader from a 1200 kV AC Power Transmission Line

UHV power transmission lines have high probability of shielding failure due to their higher height, larger exposure area and high operating voltage. Lightning upward leader inception and propagation is an integral part of lightning shielding failure analysis and need to be studied in detail. In this paper a model for lightning attachment has been proposed based on the present knowledge of lightning physics. Leader inception is modeled based on the corona charge present near the conductor region and the propagation model is based on the correlation between the lightning induced voltage on the conductor and the drop along the upward leader channel. The inception model developed is compared with previous inception models and the results obtained using the present and previous models are comparable. Lightning striking distances (final jump) for various return stroke current were computed for different conductor heights. The computed striking distance values showed good correlation with the values calculated using the equation proposed by the IEEE working group for the applicable conductor heights of up to 8 m. The model is applied to a 1200 kV AC power transmission line and inception of the upward leader is analyzed for this configuration.

Role of upward leaders in modifying the induced currents in solitary down-conductors during a nearby lightning strike to ground

Electromagnetic field produced by a lightning strike to ground causes significant induction to tall objects in the vicinity. The frequency of occurrence of such nearby ground strikes can be higher than the number of direct strikes. Therefore, a complete knowledge on these induced currents is of practical relevance. However, limited efforts towards the characterisation of such induced currents in tall down-conductors could be seen in the literature. Due to the intensification of the background field caused by the descending stepped leader, tall towers/down-conductors can launch upward leaders of significant length. The nonlinearity in the conductance of upward leader and the surrounding corona sheath can alter the characteristics of the induced currents. Preliminary aspects of this phenomenon have been studied by the author previously and the present work aims to perform a detailed investigation on the role of upward leaders in modifying the characteristics of the induced currents. A consistent model for the upward leader, which covers all the essential electrical aspects of the phenomena, is employed. A first order arc model for representing the conductance of upward leader and a field dependant quadratic conductivity model for the corona sheath is employed. The initial gradient in the upward leader and the field produced by the return stroke forms the excitation. The dynamic electromagnetic response is determined by solving the wave equation using thin-wire time-domain formulation. Simulations are carried out initially to ascertain the role of individual parameters, including the length of the upward leader. Based on the simulation results, it is shown that the upward leader enhances the induced current, and when significant in length, can alter the waveshape of induced current from bipolar oscillatory to unipolar. The duration of the induced current is governed by the length of upward leader, which in turn is dependant on the return stroke current and the effective length of the down-conductor. If the current during the upward leader developmental phase is considered along with that after the stroke termination to ground, it would present a bipolar current pulse. (C) 2015 Elsevier Ltd.

Os impactos da revolução cubana na política externa brasileira (1958 1961)

A Revolução Cubana foi o evento mais importante das relações interamericanas no século XX. Ela foi responsável pela quebra da homogeneidade da sociedade americana, introduzindo, no continente, tensões típicas da Guerra Fria. O processo revolucionário cubano obrigou aos Estados Unidos a rever a sua política para a América Latina que, entre as décadas de 1940 e 1950, tratava o subcontinente como uma área secundária. A Revolução nas Caraíbas teve impactos diretos também na formulação da política externa brasileira. Durante o governo Juscelino Kubitschek, a Operação Pan-Americana previa um plano de integração com o objetivo de eliminar o subdesenvolvimento. O rechaço da iniciativa por parte do governo cubano, foi um dos fatos determinantes para o abandono da Operação. A administração subseqüente, do presidente Jânio Quadros, foi responsável por uma profunda reformulação na diplomacia do Brasil. A Política Externa Independente previa a defesa da autodeterminação dos povos e não-intervenção em assuntos internos que, aplicados ao caso cubano, foram encarados por setores conservadores como apoio a um regime socialista. A condecoração do líder revolucionário Ernesto Che Guevara e a oposição aos princípios da Política Externa Independente (PEI) foram fatores que culminaram na renúncia do presidente brasileiro.
