Relationship Between Leader Behavior and Subordinate Organizational Commitment in Higher Education Administrators

Organizational commitment (OC) is the psychological link betrveen employees and their organizations that reduces the likelihood that ernployees rvill voluntarily leave. OC is an important dimension of organization effectiveness; it has been shown to impact productivity, work performance. and rurnover. It is instructive to recognize how a leader\u27s behavior impacts the overall stress and the organizational commitment of employees. Fifty-five administrators at a private college in the Midwest completed a 56-question electlonic survey to explore the relationship arnong leaders\u27 behavioral scores for (1a) structure-initiation and (1b) consideration as assigned by their employees and the (2) self-reported organizational commitment levels of those employees. The hypothesis that OC was highest among employees who perceived that their supervisors exhibited higher-than-average structure-initiation and consideration behaviors was supported (Spearman\u27s rho 0.416, p = .002). However, the strongest correlation was again present between leader Consideration behaviors and OC (Spearman\u27s rho 0.519. p \u3c 001)

Circumpolar Diversity and Geographic Differentiation of mtDNA in the Critically Endangered Antarctic Blue Whale (Balaenoptera musculus intermedia)

To the best of our knowledge, one or more authors of this paper were federal employees when contributing to this work.\ud This is the publisher’s final pdf. The published article is copyrighted by the Public Library of Science and can be found at: http://www.plosone.org/home.action.The Antarctic blue whale (Balaenoptera musculus intermedia) was hunted to near extinction between 1904 and 1972, declining from an estimated initial abundance of more than 250,000 to fewer than 400. Here, we describe mtDNA control region diversity and geographic differentiation in the surviving population of the Antarctic blue whale, using 218 biopsy samples collected under the auspices of the International Whaling Commission (IWC) during research cruises from 1990-2009. Microsatellite genotypes and mtDNA sequences identified 166 individuals among the 218 samples and documented movement of a small number of individuals, including a female that traveled at least 6,650 km or 131 degrees longitude over four years. mtDNA sequences from the 166 individuals were aligned with published sequences from 17 additional individuals, resolving 52 unique haplotypes from a consensus length of 410 bp. From this minimum census, a rarefaction analysis predicted that only 72 haplotypes (95% CL, 64, 86) have survived in the contemporary population of Antarctic blue whales. However, haplotype diversity was relatively high (0.968 +/- 0.004), perhaps as a result of the longevity of blue whales and the relatively recent timing of the bottleneck. Despite the potential for circumpolar dispersal, we found significant differentiation in mtDNA diversity (F-ST = 0.032, p<0.005) and microsatellite alleles (F-ST = 0.005, p<0.05) among the six Antarctic Areas historically used by the IWC for management of blue whales

A Single-Mode, Diode-Pumped Lma Laser To Probe The Spin Orientation Of Ensembles Of 3he And 4he

A diode-pumped Nd:Lanthanum Magnesium Hexaluminate laser was constructed which provides up to 15 mW of single-mode, tunable CW emission at 1083 nm. By appropriately polarizing the narrow-band laser emission (< 10 MHz), the laser can be used to determine the populations of the magnetic substates of the He ( 23S1) atoms. The laser is tuned to one of the absorption peaks of the helium metastable atom by tilting a thin (1 mm) solid, coated etalon placed inside the laser cavity and the absorption is measured. The relative absorption is used to determine the ensemble polarization ; the absolute absorption yields the metastable density

Exchange Rate Misalignment, Capital Flows, and Optimal Monetary Policy Trade-offs

What determines the optimal monetary trade-offs between internal objectives (inflation, and output gap) and external objectives (competitiveness and trade imbalances) when inefficient capital flows cause exchange rate misalignment and distort current account positions? We characterize this trade-offs analytically, using the workhorse model of modern monetary theory in open economies under incomplete markets�where inefficient capital flows and exchange rate misalignments can arise independently of nominal distortions. We derive a quadratic approximation of the utility-based global policy loss function under fairly general assumptions on preferences and openness, and solve for the optimal targeting rules under cooperation. We show that, in economies with a low degree of exchange rate pass-through, the optimal response to inefficient capital inflows associated with real appreciation is contractionary, above and beyond the natural rate: the optimal policy curbs excessive demand at the cost of exacerbating currency overvaluation. In contrast, a high degree of pass-through, and/or low trade elasticities, warrants expansionary policies that lean against exchange rate appreciation and competitive losses, at the cost of inefficient inflation

Networked markets and relational contracts

Empirical studies of commercial relationships between firms reveal that (i) suppliers encounter situations in which they can gain in the short run by acting opportunistically---for example, delivering a lower quality than promised after being paid; and (ii) good conduct is sustained not exclusively by formal contracts but through informal relationships and the expectation of future business. In such relationships, the need to offer each supplier a large enough share of future business to deter cheating limits the number of supply relationships each buyer can sustain. The market thus becomes networked, with trade restricted to durable relationships. We propose and analyze a simple dynamic model to examine the structure of such overlapping relational contracts in equilibrium. Due to exogenous stochastic shocks, suppliers are not always able to make good on their promises even if they wish to, and so links are constantly dissolving and new ones are forming to take their place. This induces a Markov process on networks. We study how the stationary distribution over networks depends on the parameters---most importantly, the value of trade and the probability of shocks. When the rate at which shocks hit increases, as might happen during an economic downturn, maintaining incentive compatibility with suppliers requires promising each more future business and this necessitates maintaining fewer relationships with suppliers. This results in a destruction of social capital, and even if the rate of shocks later returns to its former level, it can take considerable time for social capital to be rebuilt because of search frictions. This creates a novel way for shocks to be persistent. It also suggests new connections between the theory of relational contracting, on the one hand, and the macroeconomic analysis of recessions, on the other

The Acquisitions Proposals and Their Effect on Corporations, Shareholders and Creditors: Reform of Reorganizations and Liquidations

Mr. Faber sets the stage for the debate on the need for reform of our present system by summarizing some basic principles of current law, together with the exceptions that developed over the years. Mr. Faber makes the case for re-examination of Subchapter C, as well as other portions of the tax law. Mr. LeDuc seeks a framework within which to construct a tentative answer to the question that this conference is about: must corporate and shareholder income be taxed complexly? Mr. LeDuc suggests that, in order to create a framework to analyze the necessity for complexity in taxation of corporations and shareholders, we therefore have to look at the problem on both the substantive and procedural planes, and presents a four step framework to analyze the problem

Prospects for measurement and control of the scattering length of metastable helium using photoassociation techniques

A numerical investigation of two-laser photoassociation (PA) spectroscopy on spin-polarized metastable helium (He*) atoms is presented within the context of experimental observation of the least-bound energy level in the scattering potential and subsequent determination of the s-wave scattering length. Starting out from the model developed by Bohn and Julienne [Phys. Rev. A \textbf{60}, (1999) 414], PA rate coefficients are obtained as a function of the parameters of the two lasers. The rate coefficients are used to simulate one- and two-laser PA spectra. The results demonstrate the feasibility of a spectroscopic determination of the binding energy of the least-bound level. The simulated spectra may be used as a guideline when designing such an experiment, whereas the model may also be employed for fitting experimentally obtained PA spectra. In addition, the prospects for substantial modification of the He* scattering length by means of optical Feshbach resonances are considered. Several experimental issues relating to the numerical investigation presented here are discussed.Comment: 9 pages, 7 figure

Human fur gene encodes a yeast KEX2-like endoprotease that cleaves pro-beta-NGF in vivo.

Extracts from BSC-40 cells infected with vaccinia recombinants expressing either the yeast KEX2 prohormone endoprotease or a human structural homologue (fur gene product) contained an elevated level of a membrane-associated endoproteolytic activity that could cleave at pairs of basic amino acids (-LysArg- and -ArgArg-). The fur-directed activity (furin) shared many properties with Kex2p including activity at pH 7.3 and a requirement for calcium. By using antifurin antibodies, immunoblot analysis detected two furin translation products (90 and 96 kD), while immunofluorescence indicated localization to the Golgi apparatus. Coexpression of either Kex2p or furin with the mouse beta-nerve growth factor precursor (pro-beta-NGF) resulted in greatly enhanced conversion of the precursor to mature nerve growth factor. Thus, the sequence homology shared by furin and the yeast KEX2 prohormone processing enzyme is reflected by significant functional homology both in vitro and in vivo
