The Psychodynamic Limits of Fractured Relationships: When Emotional Tensile Strength is Broken

The Special Session will address factors that lead to the disintegration of once strong partnerships and alliances and outline the psychodynamic limits that lead to fractured relationships. Behavioral constructs employed in a psychiatric medicine setting will be discussed relative to their heuristic value in strategic relationship management setting. Further, the concept of emotional tensile strength will be explored

Alternative communication network designs for an operational Plato 4 CAI system

The cost of alternative communications networks for the dissemination of PLATO IV computer-aided instruction (CAI) was studied. Four communication techniques are compared: leased telephone lines, satellite communication, UHF TV, and low-power microwave radio. For each network design, costs per student contact hour are computed. These costs are derived as functions of student population density, a parameter which can be calculated from census data for one potential market for CAI, the public primary and secondary schools. Calculating costs in this way allows one to determine which of the four communications alternatives can serve this market least expensively for any given area in the U.S. The analysis indicates that radio distribution techniques are cost optimum over a wide range of conditions

Internal Marketing Implications of Workplace Bullying: The Integration of Multiple Perspectives

This special session will highlight marketing, behavioral, leadership, and legal perspectives of workplace bullying behavior and how such behavior can negatively affect an individual’s wellbeing and adversely impact an organization’s welfare. The discussion will be couched within an internal marketing framework with special emphasis on strategic implications. Behavioral aspects of those who bully and the impact that their behavior can have on their targets will be given special consideration. Also, various leadership issues that arise in workplace environments with respect to workplace bullying will be explored. Further, an overview of the legal ramifications of workplace bullying will be integrated into the discussion. Additionally, theory advancement and applied research development will be discussed as a means to stimulate additional study of the bullying phenomena. It was during the 1970s that the internal marketing concept emerged. Over time various firms gradually acknowledged the value of internal marketing programs. This adoption of internal marketing initiatives was possible because many firms recognized that internal marketing strategies were a complementary prerequisite for many external marketing efforts. The application of the IM philosophy embraced the marketing concept as it applied to employees within an organization. Under this philosophy, firms sought to recruit and retain talented people who would aspire to build and sustain relationships with customers. Although well-planned visions, missions, products, processes, and procedures were critical to such initiatives, these managerial tools have not necessarily sufficient in assuring an IM-driven environment. The panel members submit that it is also imperative to consider the impact that specific types of personal and organizational behaviors can have on internal marketing outcomes. In so doing, there is a need to recognize and acknowledge negative behaviors that can hamper, or worse yet, sabotage potential individual and group accomplishments that are in keeping with marketing goals. Many times organizations have explicitly stated the adoption of the internal marketing philosophy, The reality is, however, that workplace bullying is one form of negative behavior that may simultaneously exist even in light of noble mission statements, employee appreciation proclamations, and IM programs that declare the adherence to civil actions in a supportive work environment. In the extreme, the disconnections between explicit messages of communications and implicit messages of actions can be flagrant. The severing of organizational communications from organizational actions may manifest itself as transparent duplicity, inherent dishonesty, and disruptive affronts. In severe cases, malfeasance may thrive. The panel members will encourage audience discussion for the purposes of identifying theoretical and applied research issues and for suggesting potential research directions. Further, the SMA audience will be specifically invited to share their insights relative to IM leadership issues and bullying in the workplace. Also, panelists will encourage discussions of workplace bullying within academic settings with an emphasis on structural solutions. Questions and perceptions concerning behavioral issues will be welcomed

What Can Business Leaders Learn from Medical Misdiagnoses?

Mistakes of diagnoses are often topics in medical schools, hospitals and medical practices. These errors can range from the minor and inexpensive to the harmful and costly. According to Johns Hopkins University researchers, devastating errors can lead to permanent damage or death for as many as 160,000 patients yearly. Diagnostic errors, however, may be becoming more preventable as many health-care providers are turning to a number of innovative strategies that are addressing the complicated web of errors, biases, and oversights. Included in innovative changes in medicine are the methods of managing patients’ records through electronic means. These modernizations are often touted as part of an overall plan to provide better health care delivery which in turn will lead to more efficient and effective health outcomes. But with any automation, there are potential downsides, such as information overload. In comparison, business analytics has become a very popular and growing field of operational research with application to many areas of business. Just as in medicine, it is the mission of “big data” to provide targeted and precise information to enhance the probability of making more effective and efficient decisions. Medicine and business have many overlapping concerns around the collection, analysis, and distribution of data. Bringing these professionals together, albeit they work in different contexts, has the possibility for advancing interdisciplinary insights around major decision-making issues that are paramount to both groups. Additionally, many medical professionals are in an ongoing effort to cut down on errors of misdiagnoses through the improvements in communication. Common biases have been identified that can exacerbate physicians making an incorrect diagnosis. For example, last year Dalhousie University in Halifax, Nova Scotia established a Critical Thinking Program that aims to help identify and analyze critical thinking biases. Physician Pat Crosberry, a researcher on the role of cognitive error in diagnosis, developed a list of 50 different types of biases that lead to diagnostic error. Businesses are often involved in strategic diagnostic research and misdiagnoses in this context are always a concern too. An interdisciplinary discussion of these issues will be discussed by panelists

A novel autotransporter of uropathogenic Proteus mirabilis is both a cytotoxin and an agglutinin

One of the six predicted Proteus mirabilis autotransporters (ATs), ORF c2341, is predicted to contain a serine protease motif and was earlier identified as an immunogenic outer membrane protein in P. mirabilis . The 3.2 kb gene encodes a 117 kDa protein with a 58-amino-acid-long signal peptide, a 75-kDa-long N-terminal passenger domain and a 30-kDa-long C-terminal translocator. Affinity-purified 110 kDa AT exhibited chymotrypsin-like activity and hydrolysed N -Suc–Ala–Ala–Pro–Phe– p Na and N -Suc–Ala–Ala–Pro–Leu– p Na with a K M of 22 μM and 31 μM, respectively, under optimal pH of 8.5–9.0 in a Ca 2+ -dependent manner. Activity was inhibited by subtilase-specific inhibitors leupeptin and chymostatin. Both the cell-associated and purified form elicited cytopathic effects on cultured kidney and bladder epithelial cells. Substrate hydrolysis as well as cytotoxicity was associated with the passenger domain and was compromised upon mutation of any of the catalytic residues (Ser366, His147 and Asp533). At alkaline pH and optimal cell density, the AT also promoted autoaggregation of P. mirabilis and this function was independent of its protease activity. Cytotoxicity, autoaggregation and virulence were significantly reduced in an isogenic pta mutant of P. mirabilis . Proteus toxic agglutinin (Pta) represents a novel autotransported cytotoxin with no bacterial homologues that works optimally in the alkalinized urinary tract, a characteristic of urease-mediated urea hydrolysis during P. mirabilis infection.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/73221/1/j.1365-2958.2008.06199.x.pd

FU Orionis resolved by infrared long baseline interferometry at a 2-AU scale

We present the first infrared interferometric observations of a young stellar object with a spatial projected resolution better than 2 AU. The observations were obtained with the Palomar Testbed Interferometer. FU Ori exhibits a visibility of V^2 =0.72 +/- 0.07 for a 103 +/- 5 m projected baseline at lambda = 2.2 microns. The data are consistent on the spatial scale probed by PTI both with a binary system scenario (maximum magnitude difference of 2.7 +/- 0.5 mag and smallest separation of 0.35 +/- 0.05 AU) and a standard luminous accretion disk model (approx. accretion rate of 6e-5 Mo/yr) where the thermal emission dominates the stellar scattering, and inconsistent with a single stellar photosphere.Comment: 13 pages, 4 figures, accepted for publication in ApJ

Brewster-angle measurements of sea-surface reflectance using a high resolution spectroradiometer

This paper describes the design, construction and testing of a ship-borne spectroradiometer based on an imaging spectrograph and cooled CCD array with a wavelength range of 350-800 nm and 4 nm spectral sampling. The instrument had a minimum spectral acquisition time of 0.1 s, but in practice data were collected over periods of 10 s to allow averaging of wave effects. It was mounted on a ship's superstructure so that it viewed the sea surface from a height of several metres at the Brewster angle (53 degrees) through a linear polarizing filter. Comparison of sea-leaving spectra acquired with the polarizer oriented horizontally and vertically enabled estimation of the spectral composition of sky light reflected directly from the sea surface. A semi-empirical correction procedure was devised for retrieving water-leaving radiance spectra from these measurements while minimizing the influence of reflected sky light. Sea trials indicated that reflectance spectra obtained by this method were consistent with the results of radiance transfer modelling of case 2 waters with similar concentrations of chlorophyll and coloured dissolved organic matter. Surface reflectance signatures measured at three locations containing blooms of different phytoplankton species were easily discriminated and the instrument was sufficiently sensitive to detect solar-stimulated fluorescence from surface chlorophyll concentrations down to 1 mg m−3

Breeding latitude predicts timing but not rate of spring migration in a widespread migratory bird in South America

Identifying the processes that determine avian migratory strategies in different environmental contexts is imperative to understanding the constraints to survival and reproduction faced by migratory birds across the planet. We compared the spring migration strategies of Fork‐tailed Flycatchers (Tyrannus s. savana) that breed at south‐temperate latitudes (i.e., austral migrants) vs. tropical latitudes (i.e., intratropical migrants) in South America. We hypothesized that austral migrant flycatchers are more time‐selected than intratropical migrants during spring migration. As such, we predicted that austral migrants, which migrate further than intratropical migrants, will migrate at a faster rate and that the rate of migration for austral migrants will be positively correlated with the onset of spring migration. We attached light‐level geolocators to Fork‐tailed Flycatchers at two tropical breeding sites in Brazil and at two south‐temperate breeding sites in Argentina and tracked their movements until the following breeding season. Of 286 geolocators that were deployed, 37 were recovered ~1 year later, of which 28 provided useable data. Rate of spring migration did not differ significantly between the two groups, and only at one site was there a significantly positive relationship between date of initiation of spring migration and arrival date. This represents the first comparison of individual migratory strategies among conspecific passerines breeding at tropical vs. temperate latitudes and suggests that austral migrant Fork‐tailed Flycatchers in South America are not more time‐selected on spring migration than intratropical migrant conspecifics. Low sample sizes could have diminished our power to detect differences (e.g., between sexes), such that further research into the mechanisms underpinning migratory strategies in this poorly understood system is necessary.Fil: Jahn, Alex.
