Seasonal Shoot-Feeding by \u3ci\u3eTomicus Piniperda\u3c/i\u3e (Coleoptera: Scolytidae) in Michigan

Seasonal shoot-feeding by Tomicus piniperda (L.) was monitored at 2­ week intervals on 15 Scotch pine, Pinus sylvestris L., trees from 8 April through 16 November 1994 in southern Michigan. All shoots that showed evidence of T. piniperda attack were removed every two weeks. In 1994, initial spring flight of T. piniperda began on 22 March. At least two live T. piniperda adults were found on the 15 trees on each sampling date from 8 April through 1 November 1994. In addition, at least one freshly attacked, beetle- free shoot was found on each sampling date except for 1 November. The greatest numbers of newly attacked shoots, with or without adults present, were found from mid-June through mid-August. All adults found in April and May were likely parent adults, while those from June onward were primarily brood adults. Therefore, at all times of the year, live T. piniperda adults can be found on live pine trees, either feeding in the shoots or overwintering at the base of the trunk. Implications of these findings are provided in light of the US federal quarantine on T. piniperda

Troubleshooting Personnel’s Satisfaction with Software Tools

An exploratory survey of midsize land-grant institutions in 2016 investigated factors that were potentially correlated with how satisfied library personnel were with the software tools they used in electronic-resource troubleshooting. Although the study was very small in scale, it found that troubleshooting personnel at responding libraries are generally satisfied with the tools they use, with no apparent correlation with the area of troubleshooting activity to which the tool is applied, whether the tool is also used by non-troubleshooting personnel at the institution, or whether the tool was evaluated prior to implementation. The data weakly suggested that satisfaction was positively correlated with whether troubleshooting personnel were involved in the decision to implement the tool and negatively correlated with the length of time the tool has been in use

Free Web App Trello: Your Key to Institutional Memory in Your Subject Librarian Departments

A new subject-liaison assignment carries with it a daunting information-management challenge: Who are the faculty members in this department, and how have they worked with the previous subject librarian? Often librarians step into such a role completely blind to this history, but with an easy-to-use online tool, helpful information such as faculty photos, CVs, syllabi, assignment descriptions, research interests, collection needs, teaching schedules, notes on planning meetings and library-instruction sessions, and more can be given to a librarian along with their new subject assignment. Legwork to gather the information from department websites and personnel is required up front, but Trello, a free online application, serves as a powerful and accessible single location for storing key data in a searchable and highly visual format. And once the “board” for the department has been created and populated, it is a simple matter to attach files and summarize interactions on an ongoing basis

ALA Midwinter 2015: Issues in Resource Sharing and Implementing a Tool for Tracking Electronic-resource Outages

Among many great sessions on electronic-resource management at ALA Midwinter in Chicago, two ALCTS Interest Group (IG) meetings covered relevant ideas in considerable depth. These were the Collection Management and Electronic Resources IG meeting, on the state of resource sharing of electronic resources, and the Electronic Resources IG meeting, on tracking e-resource outages in detail. The former was in the format of an open, guided discussion on many overlapping issues while the latter was an individual presentation followed by Q&A

Tools for Troubleshooting: Which Ones and What For

A small group of midsize land-grant institutions in the western United States responded to a survey on what tools they used for troubleshooting, what activities they accomplished using the tools, and who performed their troubleshooting. Most respondents use subscription-manager administration tools, email programs, electronic resource management systems, and ticket trackers, but many other software programs are each used at a small number of institutions. Most tools support multiple troubleshooting activities, and most troubleshooting activities are supported by multiple tools. Most libraries have slightly more paraprofessionals than faculty with some troubleshooting responsibility, but nearly all have at least one of each

Static deformations from point forces and force couples located in welded elastic Poissonian half-spaces: Implications for seismic moment tensors

We present analytic expressions for the static deformations produced by point forces and point force couples embedded in two elastic Poissonian half-spaces that are welded on a horizontal interface. We show that the deformations from point forces and from vertically dipping strike-slip point double couples vary continuously (except at the strike-slip source) as the source is moved across the welded interface. We show that the pattern of deformations from vertically dipping (or horizontally dipping) dip-slip point double couples also vary continuously as the source is moved across the welded interface, but the amplitude of the deformations jumps by the ratio of the rigidities. Finally, we show that the pattern of deformation from a point explosion source or from a point double-couple source dipping at angles other than 0° or 90° jumps as the source is moved across the boundary. We demonstrate that integration of point double-couple sources on a plane of finite extent mimics the deformation of slip on a fault plane where the total moment of the double-couples is μAD. We also demonstrate that deformations from a distribution of double couples on a horizontally dipping finite plane just above the interface are indistinguishable from the deformations produced by a similar distribution of double couples located just below the interface but with a total moment that is different by the ratio of the rigidities. This demonstrates that the moment of a dislocation that occurs between two materials is ambiguously defined. We discuss reasons why seismic moment is not a very satisfying way to parameterize the size of an earthquake. We show that potency, defined to be the integral of the slip over the rupture surface, is a more natural size scaling parameter than seismic moment

Improving materials management in electronics manufacturing

The aim of this thesis is to determine how in-plant materials management in electronics manufacturing can be improved and to show how a strategy for improvement can be developed for Celestica Limited's Kidsgrove plant. The literature was reviewed to bring out the current issues and topics of interest in materials management. An industrial analysis, through company visits and case studies, was carried out. A number of "best practices" were identified from the literature and the case studies. The "best practices" identified were prioritisation methods, outsourcing of value added services, shop floor control systems, focused stores, tailored logistics, use of computers, trace ability, use of technology or automation, automatic identification, maintaining data integrity, internet-enabled supply-chain, JIT or hybridised JIT-MRP, Kanban, linking and communication of MPS's, application of technology, kitting and recording actual usage of material.

Altruism or Self-Interest? Exploring the Motivations of Open Access Authors

More than 250 authors at Utah State University published an Open Access (OA) article in 2016. Analysis of survey results and publication data from Scopus suggests that the following factors led authors to choose OA venues: ability to pay publishing charges, disciplinary colleagues’ positive attitudes toward OA, and personal feelings such as altruism and desire to reach a wide audience. Tenure status was not an apparent factor. This article adds to the body of literature on author motivations and can inform library outreach and marketing efforts, the creation of new publishing models, and the conversation about the larger scholarly publishing landscape
