Ethical Individualism in Clement of Alexandria

It has been noted that Clement of Alexandria (ca. 150-215 A. D.) diverges sharply from primitive Christianity in important respects, such as his views on eschatology and the significance of the Law. It is my contention that Clement also diverges from almost the entire previous Christian tradition as far as we know it in the matter of ethics, in that he places individual perfection above communal concerns such as love and justice

Minimal and Maximal Operator Spaces and Operator Systems in Entanglement Theory

We examine k-minimal and k-maximal operator spaces and operator systems, and investigate their relationships with the separability problem in quantum information theory. We show that the matrix norms that define the k-minimal operator spaces are equal to a family of norms that have been studied independently as a tool for detecting k-positive linear maps and bound entanglement. Similarly, we investigate the k-super minimal and k-super maximal operator systems that were recently introduced and show that their cones of positive elements are exactly the cones of k-block positive operators and (unnormalized) states with Schmidt number no greater than k, respectively. We characterize a class of norms on the k-super minimal operator systems and show that the completely bounded versions of these norms provide a criterion for testing the Schmidt number of a quantum state that generalizes the recently-developed separability criterion based on trace-contractive maps.Comment: 17 pages, to appear in JF

Service Climate, Employee Identification, and Customer Outcomes in Hotel Property Rebranding

Rebrandings have become commonplace on the hotel landscape. Research has not directly examined rebrandings from the employee's perspective, nor has previous research considered the impacts of rebranding on service quality and customer outcomes. In this paper we discuss the role of service climate and employee identification in hospitality organizations and propose a conceptual model that links service climate and employee identification with customer service and related outcomes such as word of mouth communication behaviours. As part of a larger project, 228 employees in three hotels in Australia completed a self report survey. At the time of the survey, the hotels were undergoing rebranding processes. Hierarchical multiple regression analysis investigated the relationships between the variables of interest. Preliminary findings demonstrate the significant role of customer-contact aspects of service climate and the role of employee identification with their department in predicting employee perceptions of customer outcomes. Future research is proposed

Occasional Paper No. 091-1: Small Towns Lack Capacity For Successful Development Efforts

Smalltown residents in Nebraska put a high premium on the need for economic development efforts, yet most think their towns\u27 efforts fall short. Some towns, especially the smallest, don\u27t even try to put together a development project. And those that do try often need help of a kind that State and Federal agencies do not offer. Nonetheless, Nebraska is trying some new programs that match State aid with a town\u27s needs and willingness for self-help. Based on a survey of 135 small towns in Nebraska

A review of the primary types of the Hawaiian stag beetle genus \u3ci\u3eApterocyclus\u3c/i\u3e Waterhouse (Coleoptera, Lucanidae, Lucaninae), with the description of a new species

The species of the Hawaiian stag beetle genus Apterocyclus Waterhouse (Coleoptera: Lucanidae) are reviewed following an examination of all primary types. Although the continued existence of the species is unknown and some possibly are extinct there are five recently extant species, including one species that is described here as new. The holotypes for all available names are pictured, and synonymies discussed and updated. Lectotypes are designated for Apterocyclus honoluluensis Waterhouse and A. munroi Sharp. A key to species and a revised catalog for the genus are provided

Sunmaster: An SEP cargo vehicle for Mars missions

Options are examined for an unmanned solar powered electric propulsion cargo vehicle for Mars missions. The 6 prime areas of study include: trajectory, propulsion system, power system, supporting structure, control system, and launch consideration. Optimization of the low thrust trajectory resulted in a total round trip mission time just under 4 years. The argon propelled electrostatic ion thruster system consists of seventeen 5 N engines and uses a specific impulse of 10,300 secs. At Earth, the system uses 13 engines to produce 60 N of thrust; at Mars, five engines are used, producing 25 N thrust. The thrust of the craft is varied between 60 N at Earth and 24 N at Mars due to reduced solar power available. Solar power is collected by a Fresnel lens concentrator system using a multistacked cell. This system provides 3.5 MW to the propulsion system after losses. Control and positioning to the craft are provided by a system of three double gimballed control moment gyros. Four shuttle 'C' launches will be used to transport the unassembled vehicle in modular units to low Earth orbit where it will be assembled using the Mobile Transporter of the Space Station Freedom

PtrA is required for coordinate regulation of gene expression during phosphate stress in a marine Synechococcus

Previous microarray analyses have shown a key role for the two-component system PhoBR (SYNW0947, SYNW0948) in the regulation of P transport and metabolism in the marine cyanobacterium Synechococcus sp. WH8102. However, there is some evidence that another regulator, SYNW1019 (PtrA), probably under the control of PhoBR, is involved in the response to P depletion. PtrA is a member of the cAMP receptor protein transcriptional regulator family that shows homology to NtcA, the global nitrogen regulator in cyanobacteria. To define the role of this regulator, we constructed a mutant by insertional inactivation and compared the physiology of wild-type Synechcococcus sp. WH8102 with the ptrA mutant under P-replete and P-stress conditions. In response to P stress the ptrA mutant failed to upregulate phosphatase activity. Microarrays and quantitative RT-PCR indicate that a subset of the Pho regulon is controlled by PtrA, including two phosphatases, a predicted phytase and a gene of unknown function psip1 (SYNW0165), all of which are highly upregulated during P limitation. Electrophoretic mobility shift assays indicate binding of overexpressed PtrA to promoter sequences upstream of the induced genes. This work suggests a two-tiered response to P depletion in this strain, the first being PhoB-dependent induction of high-affinity PO4 transporters, and the second the PtrA-dependent induction of phosphatases for scavenging organic P. The levels of numerous other transcripts are also directly or indirectly influenced by PtrA, including those involved in cell-surface modification, metal uptake, photosynthesis, stress responses and other metabolic processes, which may indicate a wider role for PtrA in cellular regulation in marine picocyanobacteria
