Birds are implicated in spoiling and decay of buildings, especially through their droppings. Pigeons are considered the main culprits, and several studies have examined the effects and chemistry of accumulations of droppings without evidence to the exact origins of the source of the excreta. The paper aims to discuss these issues.

This study reviews and summarises the state of knowledge with regard to the impact of bird excreta on buildings. It experimentally assesses the acidity of fresh pigeon excreta with different diets and examines the development of the acidity of the excreta after voiding.

Feral pigeons in urban settings are known to be fed by a range of foods. Urban food scraps-derived diets produce more acidic excreta than more natural diets such as seeds. This is a first study of its kind to examine the impact of a bird’s diet on the pH and thus the resulting (potential) decay of masonry.

This study showed that from a management’s perspective, pigeons that subsist entirely on human provided foods will be depositing more initially acidic faeces. If faecal accumulation occurs; then, mould and other bacteria quickly alter the chemistry from acidic towards basic, but the damage may already be done.

This paper is the first study of its kind to examine the effects of fresh pigeon droppings of known origin and age once voided from the intestine. This allows the authors to assess the impact during the first few days.

There is much anecdotal evidence that birds and their droppings are a major problem for the heritage profession. The purpose of this paper is to examine how serious heritage practitioners consider the bird impact to be.

An online survey was conducted of 59 Australian heritage professionals of between one and >20 year’s experience in the field.

Bird impacts were not considered of major concern to buildings. The longer experience a practitioner had, the less likely the impacts were considered an issue. Feral pigeons were deemed the most problematic, followed by cockatoos, starlings, swallows, seagulls, mynas, sparrows, cormorants, ibis, ducks and birds of prey. The professionals ranked common deterrent methods. The highest-ranking deterrents were bird netting and bird spikes, but they were only considered moderately effective. The costs of installation and maintenance, as well the ease of installation, were all deemed significantly less important than the physical impact, the aesthetic sympathy and the effectiveness of a deterrent method.

This study indicates that the impact of birds on buildings in Australia may be of less concern than previously thought, and may be driven by other factors (i.e. aesthetics, commercial companies) rather than actual effects.

This is first study of its kind that surveyed the experiences of a wide range of heritage practitioners.

This paper presents recently published resources on library instruction and information literacy. It provides an introductory overview and a selected annotated bibliography of publications covering various library types, study populations and research contexts. The selected bibliography is useful to efficiently keep up with trends in library instruction for busy practitioners, library science students and those wishing to learn about information literacy in other contexts.

This article annotates 424 English-language periodical articles, monographs, dissertations, theses and reports on library instruction and information literacy published in 2021. The sources were selected from the EBSCO platform for Library, Information Science, and Technology Abstracts (LISTA), Education Resources Information Center (ERIC), Scopus, ProQuest Dissertations and Theses, and WorldCat, published in 2021 that included the terms “information literacy,” “library instruction,” or “information fluency” in the title, abstract or keywords. The sources were organized in Zotero. Annotations summarize the source, focusing on the findings or implications. Each source was categorized into one of seven pre-determined categories: K-12 Education, Children and Adolescents; Academic and Professional Programs; Everyday Life, Community, and the Workplace; Libraries and Health Information Literacy; Multiple Library Types; and Other Information Literacy Research and Theory.

Mentalization is a psychodynamic concept that can help us to understand our emotional responses to others. The purpose of this paper to illustrate how the concept of mentalization may be applied in dementia care.

An autoethnographic account of the author’s experiences (first author), working as a project manager in which the author used the concept of mentalization to pay close attention to how the author’s emotional responses to people with dementia influenced thier communicative interactions.

This paper outlines how the author processed the author’s own internal experiences in both mentalizing and non-mentalizing modes, as the author wrestled with feelings of conscious incompetence. In the non-mentalizing mode, the author was pre-occupied with the author’s own anxieties. The author struggled to relate to or make sense of the experiences of the individuals with advanced dementia that the author engaged with. Moving towards a mentalizing stance helped the author to attune to the embodied experiences of the people with dementia and recognise the reciprocal nature of our communicative interactions.

This paper illustrates the role that mentalization may play in developing natural and authentic strategies to support communicative engagement in dementia care. These strategies may be of potential value to family carers. Family carers who can maintain a mentalizing stance may be more able to respond in empathic, person- centred ways to people who are living with dementia. On the other hand, non-mentalizing responses may be a root cause of mis-understanding and emotional disengagement.

Purpose – This chapter explicates the categorical resources and practices used in some disputes involving two children.

Methodology – The data on which the study is based consists of a transcript of an audio recording of the naturally occurring talk-in-interaction during a family meal. This data is analyzed using the approach of membership categorization analysis (MCA).

Findings – We show that it is neither the category collection “children” nor the category collection “siblings” that is relevant for the organization of these disputes but rather a number of asymmetrical standardized relational pairs, such as “rule-enforcer” and “offender” or “offender” and “victim.” It is these pairs of categories that are demonstrably relevant for the members, providing for and making intelligible their disputes. We then consider the question of the demonstrably relevant “wider context” of the disputes to which the disputants are actually oriented. This wider context is an omnirelevant oppositional social relationship between the children. We demonstrate that the disputes reflexively constitute the character of their oppositional relationship and show how these are instantiations of an omnirelevant category collection, namely, “parties to an oppositional relationship.”

Value of chapter – This chapter contributes to the corpus of ethnomethodological studies on children's culture in action and more particularly on the categorical organization of children's (and others’) disputes. It also contributes to MCA more generally in respect to its focus on the issues of omnirelevance and the “occasionality” of category collections.

In the preceding rules the individual biographical entry has been ignored, as it lends itself to more convenient treatment apart. Collective biography is, of course, in no way different from the ordinary book ; and the same is to be said of autobiography. Owing to the change of form in the individual biographical entry, due to the author yielding in importance to the biographee, it is usual to separate collective and individual biography in the catalogue, whether this is done on the shelves or not. Individual biography might be further separated in the catalogue into autobiographical and non‐auto‐biographical, though I cannot recall any instance where this has been carried out. In any case, it is important to distinguish in some clear way, between the subject name and the name of the author. Mere position is hardly enough ; there should be a distinction in the type. Whatever type has been employed in the other parts for author should be retained for author in the individual biograhical entry, and the subject name should be in a different type. If the author is printed in a black‐face type, as suggested in these rules, the best type for the subject name will be small capitals, as :—

The purpose of this paper is to discuss the Daisyworld “parable” advanced by James Lovelock to account for the origin of global homeostasis, and to relate it to another type of model advanced in a physiological context.

The relevance of the Daisyworld model is examined in more detail than in an earlier discussion, and the relationship to physiological rein control is considered.

Both types of model exhibit effective and robust control and there is good reason to believe they usefully model forms of biological regulation.

There are implications for theories of global homeostasis and for physiology. A computer program modelling Daisyworld is made available.

The Javascript program that can be accessed online is new, though based on the earlier work of Lovelock and Watson. Much of the treatment depends on the work of Saunders et al.
