Getting gender on the agenda: The tale of two organisations

PURPOSE - This paper aims to explore emerging issues in the application of the "dual agenda" model of gender equitable organisational change aimed at improved work life outcomes in two large Australian organisations. DESIGN/METHODOLOGY/APPROACH - The research project used the collaborative interactive action research (CIAR) methodology that underpins the dual agenda change approach. Within both organisations, a multi-method approach was used, including formal interviews, focus groups and ethnographic-style observation and interaction, as well as the analysis of a wide range of organisational documentation. The paper focuses on the challenges both for the researchers and the organisations in keeping gender on the agenda, drawing on the identification of work practices and work-life policies that impede organisational effectiveness and gender equity and the subsequent work culture diagnosis for each organisation. FINDINGS - The way in which the "gender problem" within an organisation is framed is strategically important. An understanding of "gender" as "women" not only marginalises gender equity as a business goal and its links with organisational effectiveness, but also works to silence men's interests in better work/life outcomes. A refocusing on the "ideal worker" was found to be more inclusive not only of men but also valuable in highlighting the ways in which organisational work/life policies may be undercut by business pressures and long hours, poor job design or management discretion. However, challenges remain in linking gender equitable organisational change to organisational effectiveness, especially in organisations which are restructuring and contracting in size. ORIGINALITY / VALUE - Provides a frank account of the challenges in making the links between gender equity, organisational effectiveness and work life issues that is valuable for both academics and practitioners. The "dual agenda" approach is methodologically important as it engages both "outsider" academics and "insider" organisational members in an action research process directed at gender equitable organisational change

Growing pains: work-life impacts in small-to-medium sized construction firms

Purpose - The purpose of this paper is to compare the quality of work-life experiences of workers in construction firms of differing sizes and explored the work conditions and circumstances that impact upon the work-life experiences of workers in small-to-medium sized enterprises (SMEs) in the Australian construction industry. Design/methodology/approach - Data were collected in two stages. First, data from a sub-set of construction industry workers were extracted from a large scale survey of workers in Victoria, Australia (the VicWAL survey). The survey measured work-life interference using the Australian Work and Life Index (AWALI). Next a subset of survey respondents was identified and interviewed to gain more detailed explanatory information and insight into work-life experiences. Findings - The survey results indicated that respondents who reported working for a construction firm with between 16 and 99 employees reported significantly higher AWALI scores (indicating high work-life interference) than workers in organisations employing 15 or less or more than 100 workers. The follow-up interviews revealed that workers in small construction organisations were managed directly and personally by the business owner/manager and able to access informal work-life supports that were provided on an "as needs" basis. In comparison workers in medium-sized firms perceived higher levels of work pressure and an expectation that work would be prioritised over family life. Research limitations/implications - The research shows that the findings of work-life balance research undertaken in large construction organisations cannot be generalised to SMEs. Organisation size should also be treated as an important variable in work-life balance research in construction. Practical implications - The research suggests that a better understanding of how workers in SME construction firms experience work-life balance is important in the design and development of work-life balance programs

Women\u2019s human rights when experiencing humanitarian crises and conflicts: the impact of United Nations Security Council Resolutions on women, peace, security, and the CEDAW General Recommendation no. 30.

Violence and insecurity are strictly linked to unequal political, social, and economic power. However, the continuity of violence is obscured by masculinist and patriarchal rules of security within gendered structures, especially inside the division of public/private dimensions and spaces, of production-reproduction activities, and of conflicts of war/peace. Nowadays, there is a general perception of the gendered dimensions of humanitarian emergencies in public policy outcomes and more in general in institutional contexts where the central role of women in security and maintaining peace, at all levels of decision making, both prior to, during, and after the conflict stage, hostilities, and peace-keeping and peace-building stages, as well as in trying to pursue a condition of reconciliation and reconstruction, has been formally recognized at international level. Nevertheless, it is necessary to focus on some problems related to the conceptualization of and legal provision for \u2018gender based security\u2019 and its subsequent effects upon accountability, with particular reference to transitional justice and post-conflict societies. It is important to assess a range of contemporary issues implicated for women and security, such as violence and other forms of harassment in times of post-conflict

Does Good Mutation Help You Live Longer?

We study the dynamics of an age-structured population in which the life expectancy of an offspring may be mutated with respect to that of its parent. When advantageous mutation is favored, the average fitness of the population grows linearly with time $t$, while in the opposite case the average fitness is constant. For no mutational bias, the average fitness grows as t^{2/3}. The average age of the population remains finite in all cases and paradoxically is a decreasing function of the overall population fitness.Comment: 4 pages, 2 figures, RevTeX revised version, to appear in Phys.

Survival-extinction phase transition in a bit-string population with mutation

A bit-string model for the evolution of a population of haploid organisms, subject to competition, reproduction with mutation and selection is studied, using mean field theory and Monte Carlo simulations. We show that, depending on environmental flexibility and genetic variability, the model exhibits a phase transtion between extinction and survival. The mean-field theory describes the infinite-size limit, while simulations are used to study quasi-stationary properties.Comment: 11 pages, 5 figure

Kinetic theory of age-structured stochastic birth-death processes

Classical age-structured mass-action models such as the McKendrick-von Foerster equation have been extensively studied but are unable to describe stochastic fluctuations or population-size-dependent birth and death rates. Stochastic theories that treat semi-Markov age-dependent processes using, e.g., the Bellman-Harris equation do not resolve a population's age structure and are unable to quantify population-size dependencies. Conversely, current theories that include size-dependent population dynamics (e.g., mathematical models that include carrying capacity such as the logistic equation) cannot be easily extended to take into account age-dependent birth and death rates. In this paper, we present a systematic derivation of a new, fully stochastic kinetic theory for interacting age-structured populations. By defining multiparticle probability density functions, we derive a hierarchy of kinetic equations for the stochastic evolution of an aging population undergoing birth and death. We show that the fully stochastic age-dependent birth-death process precludes factorization of the corresponding probability densities, which then must be solved by using a Bogoliubov-–Born–-Green–-Kirkwood-–Yvon-like hierarchy. Explicit solutions are derived in three limits: no birth, no death, and steady state. These are then compared with their corresponding mean-field results. Our results generalize both deterministic models and existing master equation approaches by providing an intuitive and efficient way to simultaneously model age- and population-dependent stochastic dynamics applicable to the study of demography, stem cell dynamics, and disease evolution

An Evolutionary Reduction Principle for Mutation Rates at Multiple Loci

A model of mutation rate evolution for multiple loci under arbitrary selection is analyzed. Results are obtained using techniques from Karlin (1982) that overcome the weak selection constraints needed for tractability in prior studies of multilocus event models. A multivariate form of the reduction principle is found: reduction results at individual loci combine topologically to produce a surface of mutation rate alterations that are neutral for a new modifier allele. New mutation rates survive if and only if they fall below this surface - a generalization of the hyperplane found by Zhivotovsky et al. (1994) for a multilocus recombination modifier. Increases in mutation rates at some loci may evolve if compensated for by decreases at other loci. The strength of selection on the modifier scales in proportion to the number of germline cell divisions, and increases with the number of loci affected. Loci that do not make a difference to marginal fitnesses at equilibrium are not subject to the reduction principle, and under fine tuning of mutation rates would be expected to have higher mutation rates than loci in mutation-selection balance. Other results include the nonexistence of 'viability analogous, Hardy-Weinberg' modifier polymorphisms under multiplicative mutation, and the sufficiency of average transmission rates to encapsulate the effect of modifier polymorphisms on the transmission of loci under selection. A conjecture is offered regarding situations, like recombination in the presence of mutation, that exhibit departures from the reduction principle. Constraints for tractability are: tight linkage of all loci, initial fixation at the modifier locus, and mutation distributions comprising transition probabilities of reversible Markov chains.Comment: v3: Final corrections. v2: Revised title, reworked and expanded introductory and discussion sections, added corollaries, new results on modifier polymorphisms, minor corrections. 49 pages, 64 reference

Maximum principle and mutation thresholds for four-letter sequence evolution

A four-state mutation-selection model for the evolution of populations of DNA-sequences is investigated with particular interest in the phenomenon of error thresholds. The mutation model considered is the Kimura 3ST mutation scheme, fitness functions, which determine the selection process, come from the permutation-invariant class. Error thresholds can be found for various fitness functions, the phase diagrams are more interesting than for equivalent two-state models. Results for (small) finite sequence lengths are compared with those for infinite sequence length, obtained via a maximum principle that is equivalent to the principle of minimal free energy in physics.Comment: 25 pages, 16 figure

‘They Called Them Communists Then … What D'You Call ‘Em Now? … Insurgents?’. Narratives of British Military Expatriates in the Context of the New Imperialism

This paper addresses the question of the extent to which the colonial past provides material for contemporary actors' understanding of difference. The research from which the paper is drawn involved interview and ethnographic work in three largely white working-class estates in an English provincial city. For this paper we focus on ten life-history interviews with older participants who had spent some time abroad in the British military. Our analysis adopts a postcolonial framework because research participants' current constructions of an amorphous 'Other' (labelled variously as black people, immigrants, foreigners, asylum-seekers or Muslims) reveal strong continuities with discourses deployed by the same individuals to narrate their past experiences of living and working as either military expatriates or spouses during British colonial rule. Theoretically, the paper engages with the work of Frantz Fanon and Edward Said. In keeping with a postcolonial approach, we work against essentialised notions of identity based on 'race' or class. Although we establish continuity between white working-class military emigration in the past and contemporary racialised discourses, we argue that the latter are not class-specific, being as much the creations of the middle-class media and political elite

Distribution of variation over populations

Understanding the significance of the distribution of genetic or phenotypic variation over populations is one of the central concerns of population genetic and ecological research. The import of the research decisively depends on the measures that are applied to assess the amount of variation residing within and between populations. Common approaches can be classified under two perspectives: differentiation and apportionment. While the former focuses on differences (distances) in trait distribution between populations, the latter considers the division of the overall trait variation among populations. Particularly when multiple populations are studied, the apportionment perspective is usually given preference (via FST/GST indices), even though the other perspective is also relevant. The differences between the two perspectives as well as their joint conceptual basis can be exposed by referring them to the association between trait states and population affiliations. It is demonstrated that the two directions, association of population affiliation with trait state and of trait state with population affiliation, reflect the differentiation and the apportionment perspective, respectively. When combining both perspectives and applying the suggested measure of association, new and efficient methods of analysis result, as is outlined for population genetic processes. In conclusion, the association approach to an analysis of the distribution of trait variation over populations resolves problems that are frequently encountered with the apportionment perspective and its commonly applied measures in both population genetics and ecology, suggesting new and more comprehensive methods of analysis that include patterns of differentiation and apportionment
