Microbial control of diamondback moth,Plutella xylostella L. (Lepidoptera: Yponomeutidae) using bacteria (Xenorhabdus nematophila) and its metabolites from the entomopathogenic nematode Steinernema carpocapsae

Cells and cell-free solutions of the culture filtrate of the bacterial symbiont, Xenorhabdus nematophila taken from the entomopathogenic nematode Steinernema carpocapsae in aqueous broth suspensions were lethal to larvae of the diamondback moth Plutella xylostella. Their application on leaves of Chinese cabbage indicated that the cells can penetrate into the insects in the absence of the nematode vector. Cell-free solutions containing metabolites were also proved as effective as bacterial cells suspension. The application of aqueous suspensions of cells of X. nematophila or solutions containing its toxic metabolites to the leaves represents a possible new strategy for controlling insect pests on foliage.     

CULTURE and culture at the Royal Ontario Museum: Anthropology Meets Marketing,Part 1

The museum in the contemporary era imports from the nineteenth century a venerable idea: that the first responsibility of a public art museum is to enlighten and improve its visitors, morally, socially, and politically. Yet visitors often seem to have arrived from another planet, bringing with them their own cultural meanings and agendas. A series of two articles presents ethnographic data, anthropological analysis, and a marketing perspective to suggest why the visitors' points of view may seem vertiginously strange to museum personnel. This article, Part One, characterizes the conflict between host and guest as the outcome of two competing models of culture: “preferment” and “transformation.” In a subsequent issue of Curator, Part Two will examine the influence of consumer culture on these models, and offer strategies for rapprochement.     

Conservation Heating 24 Years On

ABSTRACT

Control of relative humidity (RH) for collections care is challenging in U.K. historic houses because they are often highly ventilated with poor heat retention, a porous building fabric and naturally tend to high (60–80%) RH if unheated. The significance of the building means that large-scale modifications and installation of air handling systems may be unfeasible and undesirable for the conservation of the building. In the late 1980s the National Trust, for English, Wales and Northern Ireland, investigated conservation heating as an RH control method that works with the natural environment of historic buildings, mimicking historic heating and requiring only modification of existing heating services or a light touch installation of new heating systems. The National Trust adopted conservation heating as its preferred method for environmental control in historic buildings from the 1990s. This method was presented at the IIC 1994 Ottawa congress on preventive conservation. Conservation heating has since been adopted by many historic house management organisations, particularly across north-west Europe, where it is well suited to the climate. This paper reviews conservation heating developments implemented by the National Trust since 1994, in response to a changing external context, new knowledge and developments in operational practice.     

Are you a budding academic writer?

Academic writing can seem a daunting prospect although with the right support and information it can be more achievable than you think. In this first set of editorial comments of 2016, editors from all sections of the Health Information and Libraries Journal outline the origins of the individual section of the journal which they oversee and highlight some of the things you might want to consider when thinking of submitting your writing for publication.     

Big Data – What is it and why it matters

Big data, like MOOCs, altmetrics and open access, is a term that has been commonplace in the library community for some time yet, despite its prevalence, many in the library and information sector remain unsure of the relationship between big data and their roles. This editorial explores what big data could mean for the day‐to‐day practice of health library and information workers, presenting examples of big data in action, considering the ethics of accessing big data sets and the potential for new roles for library and information workers.     

DEVELOPING PARENT‐PROFESSIONAL PARTNERSHIPS IN A POSTSECONDARY EDUCATION PROGRAM FOR STUDENTS WITH DISABILITIES

Opportunities are increasing for students with intellectual and/or developmental disabilities to attend postsecondary education programs located at college campuses around the nation. Students who attend postsecondary education programs experience numerous positive outcomes, including independent living skills and expanded social networks. However, although parent‐professional partnerships could significantly enhance long‐term outcomes such as competitive employment and independent living, there is a paucity of information about the nature of these partnerships in postsecondary settings. The purpose of this expository article is to describe how staff from a midwestern postsecondary education program facilitate parent‐professional partnerships through parent involvement and support.
