Establishment of the Alfalfa Weevil Parasite \u3ci\u3eMicroctonus Aethiopoides (Hymenoptera: Braconidae)\u3c/i\u3e in Michigan

Microctonus aethiopoides, a braconid parasite of adult alfalfa weevil, Hypera postica, is now established in southeastern Minnesota. Releases were made near Caledonia in Houston County, in 1978 and 1979, and near Rosemount in Dakota County, in 1979 and 1980. M. aethiopoides was recovered in Houston County in 1979, a new state record, and since has expanded its range more than 40 km from the release site. Establishment in Dakota County was unexpected because of low host densities, but parasites were recovered there in 1983. Other workers have recovered M. aethiopoides in Olmstead County

Conflict Styles and College Roommates

This project focuses on the conflict that occurs between roommates and proposes an hour and a half training module designed to help participants understand the impact of conflict on their relationships and to develop strategies for improved conflict resolution in the future. The training will be based on the Thomas-Kilmann MODE Instrument, history of conflict styles, and how conflict and conflict styles affect roommate conflict

Training healthcare assistants working in adult acute inpatient wards in Psychological First Aid: An implementation and evaluation study.

WHAT IS KNOWN ON THE SUBJECT: Healthcare assistants are untrained and unregistered frontline staff but are expected to be proactive in preventing and responding to 'untoward' incidents quickly and efficiently when working within adult acute inpatient psychiatric settings. Healthcare assistants should be trained to provide enhanced care to service users residing in acute psychiatric settings. To date, a training programme in Psychological First Aid has not been expended in such a setting with nonregistered staff. WHAT THE PAPER ADDS TO EXISTING KNOWLEDGE: The study demonstrates that training healthcare assistants in Psychological First Aid is useful in improving their confidence in caring for service users, therapeutic engagement with service users and ward culture in general. WHAT ARE THE IMPLICATIONS FOR PRACTICE: A training programme in Psychological First Aid for healthcare assistants to enhance ward culture can be implemented in different practice environments. Psychological First Aid is harmonious with nursing values and provides healthcare assistants with a relevant, useful and easily understood toolkit to apply in acute psychiatric settings. ABSTRACT: Introduction Healthcare assistants working within adult acute inpatient psychiatric settings are untrained and unregistered, however, they can contribute to quality service if they receive some training. Psychological First Aid training has never been expended in these settings, so this study intends to fill this gap in the existing evidence with this category of healthcare personnel. Aim The aim of this study was to introduce and evaluate first aid training for healthcare assistants. Method A pre/post design was adopted to gather data using questionnaires and interviews. The groups of participants included 16 healthcare assistants trained in Psychological First Aid, a sample of service users and four ward managers. Results Post-training, (a) healthcare assistants and service users ranked the therapeutic milieu of the ward more favourably, (b) the self-efficacy of the healthcare assistants increased, and the number of 'untoward' incidents decreased, and (c) health care assistants' confidence in their skills was high. The ward manager interviews post-training revealed four themes: (a) staff utilization of new skills and renewed enthusiasm, (b) calmer atmosphere on the ward and staff togetherness, (c) confidence and reflection on practice and (d) therapeutic engagement. Discussion Training healthcare assistants is useful in improving staff confidence, therapeutic engagement with service users and ward culture in general. Implications for practice Techniques and skills learnt are relevant and useful to healthcare assistants and provide an easily understood toolkit that is harmonious with nursing values. If executed correctly, the training can enhance practice and care outcomes and the overall service user experience

Roaring nineties: Accounting history comes of age

The paper outlines developments in the accounting history literature during the 1990s. The introduction chronicles the immense broadening of publication opportunities in accounting history that characterized the decade. To a certain extent, this enhancement of outlets resulted from a richer dialogue among accounting historians who became increasingly willing to debate paradigmatic and methodological issues. In this context, the paper identifies and discusses traditional and critical forms of accounting history and reviews work within the paradigms of economic-rationalist, Foucauldian, and Marxist/labor-process studies. The major elements of debate between old and new perspectives on accounting history are discussed and linked to later collaborative efforts and refinements in the work of each genre. Major research projects published during the 1990s are identified, tabulated, and discussed. The paper concludes with a discussion of accounting history as the decade closed, with a particular focus on the opportunities and threats that may lie ahead for the field

Simulation of fluid flows during growth of organic crystals in microgravity

Several counter diffusion type crystal growth experiments were conducted in space. Improvements in crystal size and quality are attributed to reduced natural convection in the microgravity environment. One series of experiments called DMOS (Diffusive Mixing of Organic Solutions) was designed and conducted by researchers at the 3M Corporation and flown by NASA on the space shuttle. Since only limited information about the mixing process is available from the space experiments, a series of ground based experiments was conducted to further investigate the fluid dynamics within the DMOS crystal growth cell. Solutions with density differences in the range of 10 to the -7 to 10 to the -4 power g/cc were used to simulate microgravity conditions. The small density differences were obtained by mixing D2O and H2O. Methylene blue dye was used to enhance flow visualization. The extent of mixing was measured photometrically using the 662 nm absorbance peak of the dye. Results indicate that extensive mixing by natural convection can occur even under microgravity conditions. This is qualitatively consistent with results of a simple scaling analysis. Quantitave results are in close agreement with ongoing computational modeling analysis

Coherent states for a particle on a sphere

The coherent states for a particle on a sphere are introduced. These states are labelled by points of the classical phase space, that is the position on the sphere and the angular momentum of a particle. As with the coherent states for a particle on a circle discussed in Kowalski K {\em et al} 1996 {\em J. Phys. A} {\bf 29} 4149, we deal with a deformation of the classical phase space related with quantum fluctuations. The expectation values of the position and the angular momentum in the coherent states are regarded as the best possible approximation of the classical phase space. The correctness of the introduced coherent states is illustrated by an example of the rotator.Comment: LaTeX, 16 pages, 2 figure

Proof of an entropy conjecture for Bloch coherent spin states and its generalizations

Wehrl used Glauber coherent states to define a map from quantum density matrices to classical phase space densities and conjectured that for Glauber coherent states the mininimum classical entropy would occur for density matrices equal to projectors onto coherent states. This was proved by Lieb in 1978 who also extended the conjecture to Bloch SU(2) spin-coherent states for every angular momentum $J$. This conjecture is proved here. We also recall our 1991 extension of the Wehrl map to a quantum channel from $J$ to $K=J+1/2, J+1, ...$, with $K=\infty$ corresponding to the Wehrl map to classical densities. For each $J$ and $J<K\leq \infty$ we show that the minimal output entropy for these channels occurs for a $J$ coherent state. We also show that coherent states both Glauber and Bloch minimize any concave functional, not just entropy.Comment: Version 2 only minor change

Memetic Multilevel Hypergraph Partitioning

Hypergraph partitioning has a wide range of important applications such as VLSI design or scientific computing. With focus on solution quality, we develop the first multilevel memetic algorithm to tackle the problem. Key components of our contribution are new effective multilevel recombination and mutation operations that provide a large amount of diversity. We perform a wide range of experiments on a benchmark set containing instances from application areas such VLSI, SAT solving, social networks, and scientific computing. Compared to the state-of-the-art hypergraph partitioning tools hMetis, PaToH, and KaHyPar, our new algorithm computes the best result on almost all instances

Two-photon excitation and relaxation of the 3d-4d resonance in atomic Kr

Two-photon excitation of a single-photon forbidden Auger resonance has been observed and investigated using the intense extreme ultraviolet radiation from the free electron laser in Hamburg. At the wavelength 26.9 nm (46 eV) two photons promoted a 3d core electron to the outer 4d shell. The subsequent Auger decay, as well as several nonlinear above threshold ionization processes, were studied by electron spectroscopy. The experimental data are in excellent agreement with theoretical predictions and analysis of the underlying multiphoton processes

SU(N) Coherent States and Irreducible Schwinger Bosons

We exploit the SU(N) irreducible Schwinger boson to construct SU(N) coherent states. This construction of SU(N) coherent state is analogous to the construction of the simplest Heisenberg-Weyl coherent states. The coherent states belonging to irreducible representations of SU(N) are labeled by the eigenvalues of the $(N-1)$ SU(N) Casimir operators and are characterized by $(N-1)$ complex orthonormal vectors describing the SU(N) group manifold.Comment: 12 pages, 3 figure
