    Of what use are flies, anyway? This and similar questions have frequently been asked of the writer by persons who seem to think that each and every living thing has been created solely for some special benefit to man. Primarily the common house fly (Musca domestica), together with several of its allies which habitually frequent human habitations, are scavengers. In this role they assist in the removal of filth and litter of various sorts that too often are permitted to accumulate in the vicinity of our homes, schools, offices, and \u27 places of business or pleasure. These flies lay their eggs upon such materials as manure, decaying vegetable matter, sewage, and other filth. The resulting maggots devour these substances, hence are, to a considerable degree, beneficial. The house fly has become so widely and generally disseminated in its distribution over the earth\u27s surface that it may be considered cosmopolitan. Although primarily a denizen of human habitations, it seems to be present also in such out-of-the-way places as uninhabited localities in dense forests, wide prairies, and wild mountain fastnesses. In localities like these latter it is very quickly attracted by the odor of different foods upon which it congregates along with several other kinds of dies possessing similar food-habits. Since the life-history of several different species of these flies is somewhat similar, that of one of them will answer for all, so far at least as present purposes are concerned

    Insect Enemies of the Small Grains

    Although corn is king in Nebraska, our crops of small grains are not insignificant. The insect enemies of wheat, oats, barley, and rye therefore demand our attention nearly or quite as much as do those which attack corn. Accordingly, during the past year much time has been given to the study of this class of insect pests. While many of the species are identical for the different crops, the nature of the plants themselves being unlike, it necessarily follows that the mode of attack among these enemies must vary somewhat in each case. This being true, some pains has been taken to beat of them according to their host plants. While it is not claimed that this paper is complete or even original, it cannot strictly be termed a compilation. All that the writer hopes in its presentation is that it may be of some little value to those for whom it is intended, and that through its influence some efforts may be made towards protecting our crops from the ravages of these insect pests

    A PRELIMINARY REVIEW OF THE BIRDS OF NEBRASKA WITH SYNOPSES

    Get PDF
    In 1896, Prof. Bruner published his list entitled Some Notes on Nebraska Birds. As a working basis for the study of the ornithology of the state it has proven invaluable and it has also been greatly in demand by people not ornithologists, who desired to know something about our birds. That edition was exhausted some time ago and its author has been frequently urged to publish another. However, the organization of the Nebraska Ornithologists\u27 Union and the development of ornithology in the University has led to such a rapid increase in our knowledge in the past five years that it seemed that any publication would soon become out of date, and so no one ventured to undertake the task. It is under these conditions that the opportunity has been offered, through the kindness of Ex-Governor Furnas, Secretary of the State Board of Agriculture, and an enthusiastic member of the Union, to prepare something on the birds of the state. It seemed too good an opportunity to be lost, and yet, under the circumstances, the authors of this contribution feel that it can only be considered, as its title states, as a preliminary review. It should be understood, nevertheless, preliminary in one sense as it is, that it has been prepared with the greatest care, and is believed to represent exactly the state of our knowledge at the present, day. Every species has been carefully considered, the specimens available examined, its occurrence in surrounding states studied, the records in Bruner\u27s list thoroughly canvassed, as well as all data which have accumulated since, and the whole reduced to such statements as indicate clearly the limits of our knowledge in regard to the form under consideration. All specimens about which there could be any doubt were sent to authorities east for exact determination. Those species that have been\u27 previously reported from Nebraska but the right of which to a place in our fauna is questioned or denied have been introduced, but in brackets. There have also been added under the phrase extralimital those species which may possibly be found in the state in the future. 125 pages. Includes Index.

    Feasibility of Patient Reporting of Symptomatic Adverse Events via the Patient-Reported Outcomes Version of the Common Terminology Criteria for Adverse Events (PROCTCAE) in a Chemoradiotherapy Cooperative Group Multicenter Clinical Trial

    Purpose—To assess the feasibility of measuring symptomatic adverse events (AEs) in a multicenter clinical trial using the National Cancer Institute’s Patient-Reported Outcomes version of the Common Terminology Criteria for Adverse Events (PRO-CTCAE). Methods and Materials—Patients enrolled in Trial XXXX (XXXX) were asked to self-report 53 PRO-CTCAE items representing 30 symptomatic AEs at 6 time points (baseline; weekly x4 during treatment; 12-weeks post-treatment). Reporting was conducted via wireless tablet computers in clinic waiting areas. Compliance was defined as the proportion of visits when an expected PRO-CTCAE assessment was completed. Results—Among 226 study sites participating in Trial XXXX, 100% completed 35-minute PROCTCAE training for clinical research associates (CRAs); 80 sites enrolled patients of which 34 (43%) required tablet computers to be provided. All 152 patients in Trial XXXX agreed to selfreport using the PRO-CTCAE (median age 66; 47% female; 84% white). Median time for CRAs to learn the system was 60 minutes (range 30–240), and median time for CRAs to teach a patient to self-report was 10 minutes (range 2–60). Compliance was high, particularly during active treatment when patients self-reported at 86% of expected time points, although compliance was lower post-treatment (72%). Common reasons for non-compliance were institutional errors such as forgetting to provide computers to participants; patients missing clinic visits; internet connectivity; and patients feeling “too sick”. Conclusions—Most patients enrolled in a multicenter chemoradiotherapy trial were willing and able to self-report symptomatic adverse events at visits using tablet computers. Minimal effort was required by local site staff to support this system. The observed causes of missing data may be obviated by allowing patients to self-report electronically between-visits, and by employing central compliance monitoring. These approaches are being incorporated into ongoing studies

    Identity, Collaboration and Radical Innovation: The Role of Dual Organisation Identification

    Get PDF
    This paper explores the nature of the relationship between identity and the radical innovation process in the case of the Solid State Pharmaceutical Cluster (SSPC). Antecedents and consequences of identification with the SSPC and the transitioning of identify from an organizational orientation to a dual organisation identity are discussed. We demonstrate that organizational identity can represent a substantial barrier to collaborating for radical innovation, and explicate how identity shifts can smooth the transition from competitor to collaborator. This study illustrates that opportunities were created through leveraging affinity to provide an environment conducive to radical innovation where members could interact, explore and collaborate

    The Problem of Experience in the Study of Organizations

    Full text link
    This paper deals with the fact that we cannot experience large organizations directly, in the same way as we can experience individuals or small groups, and that this non-experientiability has certain implications for our scientific theories of organizations. Whereas a science is animated by a constructive interplay of theory concepts and experience concepts, the study of organizations has been confined to theory concepts alone. Implications of this analysis for developing a science of organizations are considered.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/68303/2/10.1177_017084069301400102.pd

    Exploring gender and fear retrospectively:stories of women’s fear during the ‘Yorkshire Ripper’ murders

    Get PDF
    The murder of 13 women in the North of England between 1975 and 1979 by Peter Sutcliffe who became known as the Yorkshire Ripper can be viewed as a significant criminal event due to the level of fear generated and the impact on local communities more generally. Drawing upon oral history interviews carried out with individuals living in Leeds at the time of the murders, this article explores women’s accounts of their fears from the time. This offers the opportunity to explore the gender/fear nexus from the unique perspective of a clearly defined object of fear situated within a specific spatial and historical setting. Findings revealed a range of anticipated fear-related emotions and practices which confirm popular ‘high-fear’ motifs; however, narrative analysis of interviews also highlighted more nuanced articulations of resistance and fearlessness based upon class, place and biographies of violence, as well as the way in which women drew upon fear/fearlessness in their overall construction of self. It is argued that using narrative approaches is a valuable means of uncovering the complexity of fear of crime and more specifically provides renewed insight onto women’s fear
