    The Business of Human Resources

    [Excerpt] The result of this missing ingredient is the basic reason for the variability that exists within the profession. In fact, a lot of business leaders do not clearly understand what HR is responsible or accountable for. Many are quick to relegate HR to social initiatives planning (e.g., United Way drives, company picnics), missing the value the function can provide to the business. In this paper I seek to address these issues by suggesting a four-factor framework for running the HR function like a business: (1) understanding the business HR is supporting, (2) developing a basic operating philosophy, (3) determining which HR products and services should be linked directly to business success, and (4) operating HR as a business

    Corticofugal projections from the anterior olfactory nucleus target olfactory bulb principal cells

    The anterior olfactory nucleus (AON) is a cortical structure reciprocally connected with the olfactory bulb (OB) and the piriform cortex. Here, using small extracellular and intracellular injections to trace the terminal projections in the OB from individual cells in the rat AON, and examining the morphology and distribution of these projections, I report that these projections appear to preferentially target and directly synapses with mitral cells. These findings suggests that the AON acts to modulate incoming olfactory information based on ongoing processing, perhaps in a way that tunes the OB to signal the presence of particular odors

    On Menger, Austrian Economics, and the Use of General Equilibrium.

    Nowadays mainstream economic textbooks maintain that economic laws can be established solely on the foundations of the exact sciences, such as mathematics or physics. The implication is that the historical date collected with the aid of statistics and other technical means can be used to scientifically unveil, explain, and predict mankind’s behavior. Although economics today embodies individual tastes in the form of elegant charts that are depicted in text books as ‘indifference curves’, it has not gone further in characterizing the all important motivations, influences, or feelings of the acting individuals. If the sole purpose of economic research is to analyze the properties of general equilibrium in the conditions of perfect knowledge and perfect competition, this may well suffice. It seems as if all approaches to economic phenomena which do not follow this doctrine are quickly branded unscientific and repudiated. Rather than constructing a system of timeless general equilibrium prices, as is the goal of the mathematically oriented schools of thought, in our world of scarcity, lack or dispersion of knowledge, and ever changing degrees of expectations, the Austrians attempt to explain the forces and causes that stand behind the price formation. The two main pillars of the Austrian school of economics are methodological individualism (a term used by J.A. Schumpeter) and methodological subjectivism. This approach to economic phenomena builds scientific analysis upon the insight that every individual chooses and acts purposively and in accordance with his perception of the expected actions of others. In observing the actions of others we are aided by our ability to “understand” the meaning of such actions because we are human beings and thus have insights into the behavior of our fellow men.

    Traffic Analysis for the Calibration of Risk Assessment Methods

    In order to provide some measure of the uncertainty inherent in the sorts of charting data that are provided to the end-user, we have previously proposed risk models that measure the magnitude of the uncertainty for a ship operating in a particular area. Calibration of these models is essential, but the complexity of the models means that we require detailed information on the sorts of ships, traffic patterns and density within the model area to make a reliable assessment. In theory, the ais system should provide this information for a suitably instrumented area. We consider the problem of converting, filtering and analysing the raw ais traffic to provide statistical characterizations of the traffic in a particular area, and illustrate the method with data from 2008-10-01 through 2008-11-30 around Norfolk, VA. We show that it is possible to automatically construct aggregate statistical characteristics of the port, resulting in distributions of transit location, termination and duration by vessel category, as well as type of traffic, physical dimensions, and intensity of activity. We also observe that although 60 days give us suffi- cient data for our immediate purposes, a large proportion of it—up to 52% by message volume—must be considered dubious due to difficulties in configuration, maintenance and operation of ais transceivers

    Establishing a Regional AIS Application Specific Message Register

    Get PDF
    The goal of the Regional AIS Application Specific Message Register is to provide awareness of what applications exist, facilitate harmonization, and promote proper binary messaging for regional applications. To be hosted on the IALA website, establishing the Register will be a 3-step process: 1) Compile all existing AIS binaries into a Jcollection.K 2) Convert the JcollectionK into a Register. 3) Develop IALA guidance on best practices for creating and using AIS Binary Messages. Recommendations are provided in regard to: - Benefit of a web-based HTML user interface for input/output. - Use of XML to organize/format register applications in a consistent manner. - Having the collection/registration become a JloopK process. - Conforming to ISO standards to organize and manage the Register. - Benefit of a joint IMO-IALA register for both international and regional applications

    Gatekeeping in health care

    We study the competitive effects of restricting direct access to secondary care by gatekeeping, focusing on the informational role of gatekeeping general practitioners (GPs). We consider a secondary care market with two hospitals choosing the quality and specialisation of their care. GPs perfectly observe the diagnosis of a patient and the exact characteristics of the secondary care market. Patients are either informed or uninformed when accessing the hospital market. We consider two distinct cases: first, we let the fraction of informed patients be exogenous, implying that the regulator can only influence patients' decision of consulting a GP by making this compulsory ('direct gatekeeping'). Second, we endogenise this fraction by assuming GP consultation to be costly for the patient. Then the reulator can influence the GP attendance rate through the regulated price ('indirect gatekeeping'). A main finding of the paper is that strict gatekeeping may not be socially desirable, even if it is costless.Gatekeeping; Imperfect information; Quality competition; Product differentiation; Price regulation

    Interannual variation of seasonal means and subseasonal variability of cloud streets off the east coast of North America 1984-1987

    Convection waves are a strong function of the original forcing by convection in the boundary layer. This convection can take the form of random or 2-D spatial structure. When clouds are formed as a result of 2-D boundary layer forcing, they are called cloud streets. Convective waves may be important in the global momentum balance. Global circulation models presently overestimate wind speeds in the middle and upper troposphere, and do not account for convective waves. If the hypothesis that convective waves significantly contribute to momentum transport in the troposphere is correct, then climatology of cloud streets will help understand convective waves' role in the global momentum balance. If the hypothesis is incorrect, then cloud street climatology is still useful because cloud streets show areas where large amounts of sensible and latent heat are transferred from the ocean to the atmosphere. Interannual variation of seasonal means and subseasonal variability of cloud street occurrence off the east coast of North America is examined and compared. The months of Dec., Jan., and Feb. during 1984-85, 1985-86, and 1986-87 are examined along with each season
