The influence of riparian corridor width on ant and plant assemblages in northern Sydney,Australia

Protecting riparian corridors is a commonly applied environmental policy in urban landscapes. However, empirical data demonstrating their efficacy for biodiversity conservation outcomes is scarce. In this study we investigated whether riparian corridor width influences the diversity and community structure of ant (Hymenoptera: Formicidae) and vascular plant assemblages therein. Eighteen corridors of differing widths were selected from within the Ku-ring-gai Local Government Area, Sydney Australia. Ants were sampled using pitfall traps positioned within rectangular vegetation transects (30 × 10 m). Both ant and plant species richness, when standardised for sampling effort, were unrelated to riparian corridor width. However, significant compositional differences between sites were evident with increased width up to ~50 m. Narrow corridors contained greater abundances of opportunistic ant species and higher proportions of exotic plants. We interpret this to be the result of the greater disturbance/edge influence derived from adjacent upland urban environments. Site beta diversity did not increase with corridor width, suggesting that the exclusion of novel upslope habitats in narrow riparian corridors is not a significant cause of community assemblage modification at these sites. To minimise the impact of deleterious edge effects on ant fauna, environmental managers should seek to retain riparian corridors wider than ~50 m. However, we observed substantial between-site variability of biotic assemblages, irrespective of corridor width. Therefore we recommend that environmental management practice needs to take a catchment-wide approach and consider other parameters that may contribute to riparian health so as to optimise the protection of riparian biodiversity.     

Researching community,work and family with an interpreter

Community, work and family have been studied as practice and experience on an international scale. This work has included research with ethnic minority groups, usually practised by 'insiders' who share their participants' ethnicity, culture and first language. Many of these people live and work in extended family networks, part of a relatively small community embedded within a larger one. Generally, researchers do not have the language skills necessary to communicate with a linguistically diverse population. However, there has been a call to give a voice to, and hence empower, minority groups through the research process. It is in this context that a consideration of the use of interpreters in research on community, work and family can be made. Within this paper we present exploratory suggestions, drawn from our own research, for the appropriate use of an interpreter. This includes a discussion of the practical considerations and implications involved in this research activity, as well as more conceptual issues. Finally, the ways in which this research activity should be documented to reflect concerns in current qualitative methodological debates are considered. La communauté, le travail et la famille sont des sujets qui ont été étudiés, tant au niveau de la pratique que de l'expérience, à l'échelon international. Cette étude a envelopéune recherche parmi les groupes éthniques en minorité, dans l'ensemble vécue par des gens qui connaissent les choses de l'intérieur et qui partagent l'identité éthnique, la culture et la langue maternelle. Nombreux, parmi eux, sont des gens qui vivent et travaillent dans le cadre de familles étendues et font partie d'une petite communauté au sein d'une communaute plus grande. Dans l'ensemble, les chercheurs n'ont pas les competences linguistiques nécessaires pour communiquer avec une population de langues diverses. Cependant, il s'est avéré qu'il est plus que nécessaire de donner la parole et, de là, donner le pouvoir, aux groupes minoritaires au travers de la procedure du travail de recherche. C'est dans ce contexte que la considération de l'utilité de faire appel à des interprètes dans le domaine de la recherche qui embrasse la communauté, le travail et la famille, peut etre faite. Dans ce papier, nous soumettons des suggestions exploratoires, tirées de notre propre recherche, pour l'utilisation appropriée d'un interprete. Cela inclue une discussion sur les considerations pratiques et les implications contenues dans l'activite de cette recherche, y compris des activités conceptuelles. Pour finir, nous considérons la manière dans laquelle cette recherche devrait être documentée afin de refléter les débats méthodologiques qualitatifs en cours.     

Long range planning of paper and board supplies

Most standard textbooks identify three essential elements of effective corporate planning: an information input of appropriate depth, critical appraisal of the company's relative position and application of advanced evaluation techniques. Extension of the vision period, for long range or strategic planning, will unavoidably introduce further complexities into these constituent routines of corporate planning as well as into the strategic decision making process. The author reviews the long term outlook for paper and board suppliers and users and points out the strategic advantages of these basic materials.     

Risk Factors for Clinically Significant Intimate Partner Violence Among Active‐Duty Members

Hypothesized risk factors for men's and women's clinically significant intimate partner violence (CS‐IPV) from four ecological levels (i.e., individual, family, workplace, community) were tested in a representative sample of active‐duty U.S. Air Force members (N = 42,744). When considered together, we expected only individual and family factors to account for unique variance in CS‐IPV perpetration. Hypothesized factors from all four ecological levels were related to men's CS‐IPV perpetration bivariately, but, as expected, only individual and family factors accounted for unique variance across ecological levels. For women, only risk factors from the individual and family levels were significantly related to CS‐IPV perpetration even bivariately. Results imply somewhat different risk profiles across gender and identify ecological risk factors of men's CS‐IPV not previously studied.     

Service robotics: do you know your new companion? Framing an interdisciplinary technology assessment

Service-Robotic—mainly defined as “non-industrial robotics”—is identified as the next economical success story to be expected after robots have been ubiquitously implemented into industrial production lines. Under the heading of service-robotic, we found a widespread area of applications reaching from robotics in agriculture and in the public transportation system to service robots applied in private homes. We propose for our interdisciplinary perspective of technology assessment to take the human user/worker as common focus. In some cases, the user/worker is the effective subject acting by means of and in cooperation with a service robot; in other cases, the user/worker might become a pure object of the respective robotic system, for example, as a patient in a hospital. In this paper, we present a comprehensive interdisciplinary framework, which allows us to scrutinize some of the most relevant applications of service robotics; we propose to combine technical, economical, legal, philosophical/ethical, and psychological perspectives in order to design a thorough and comprehensive expert-based technology assessment. This allows us to understand the potentials as well as the limits and even the threats connected with the ongoing and the planned implementation of service robots into human lifeworld—particularly of those technical systems displaying increasing grades of autonomy.     

A Discrete Variable Chain Graph for Applicants for Credit

A bank offering unsecured personal loans may be interested in several related outcome variables, including defaulting on the repayments, early repayment or failing to take up an offered loan. Current predictive models used by banks typically consider such variables individually. However, the fact that they are related to each other, and to many interrelated potential predictor variables, suggests that graphical models may provide an attractive alternative solution. We developed such a model for a data set of 15 variables measured on a set of 14 000 applications for unsecured personal loans. The resulting global model of behaviour enabled us to identify several previously unsuspected relationships of considerable interest to the bank. For example, we discovered important but obscure relationships between taking out insurance, prior delinquency with a credit card and delinquency with the loan.     

Designing an ADP planning process

A great deal has been written about the frustrations of carrying out long range planning in large organizations. Although far less has been written about ADP planning, similar frustrations (as well as benefits) have been suggested.The case study described in this article deals with the recent experiences of a large, federal regulatory agency— the Food and Drug Administration—in the design and implementation of an ADP planning process from 1974 to the present. Although the process was designed to meet the Agency's specific needs, many of the lessons learned will be useful to others contemplating a process for their organization (public or private).
