Is the Learning Organization for Real? Examining the Impacts of the Dimensions of the Learning Organization on Organizational Performance

Despite the controversial nature of the learning organization concept, few empirical studies have examined the relationship between the learning organization concept and firm performance. An exploratory study was conducted using the DLOQ© along with objective measures of firm financial performance to assess this association. Findings suggest positive associations between the learning organization concept and firm performance

A MICROCOMPUTER ANALYSIS OF FARM FINANCIAL PERFORMANCE

This article describes the properties of the Farm Financial Simulation Model (FFSM). FFSM is a tool for analyzing the financial consequences of various managerial strategies and policy options that may be implemented in responding to farm financial stress. Various farm types from different geographical regions having differing enterprises, financial structures, tenure arrangements, and consumption patterns can be analyzed. The emphasis of FFSM is placed on modeling a farm's profitability, liquidity, solvency, and financial position and the model produces a coordinated set of financial statements and an extensive set of financial ratios over a four-year period.Farm Management,

The Ideal Review Process Is a Three-Way Street

In response to the increasing difficulty of obtaining high quality peer reviews, our invited paper describes the concept of review avoidance and why this phenomenon occurs. In reaffirming the professional responsibilities and potential benefits of reviewing, we also emphasize the interdependent nature of the ideal peer review process. We suggest that the review process is a three-way street where the respective roles and responsibilities of authors, editors and editorial teams, and reviewers are inextricably linked. We present thematic illustrations of undesirable reviewer comments, and a brief synthesis of broad themes in the literature on high-quality reviewing. The synthesis is complemented by a master reviewer’s fine-grained perspective on crafting high quality reviews. A final Appendix presents additional sources that may be informative for prospective reviewers, submitting authors, and those mentors and colleagues who may wish to provide guidance and training to them

Generalized (m,k)-Zipf law for fractional Brownian motion-like time series with or without effect of an additional linear trend

We have translated fractional Brownian motion (FBM) signals into a text based on two ''letters'', as if the signal fluctuations correspond to a constant stepsize random walk. We have applied the Zipf method to extract the $\zeta '$ exponent relating the word frequency and its rank on a log-log plot. We have studied the variation of the Zipf exponent(s) giving the relationship between the frequency of occurrence of words of length $m<8$ made of such two letters: $\zeta '$ is varying as a power law in terms of $m$. We have also searched how the $\zeta '$ exponent of the Zipf law is influenced by a linear trend and the resulting effect of its slope. We can distinguish finite size effects, and results depending whether the starting FBM is persistent or not, i.e. depending on the FBM Hurst exponent $H$. It seems then numerically proven that the Zipf exponent of a persistent signal is more influenced by the trend than that of an antipersistent signal. It appears that the conjectured law $\zeta ' = |2H-1|$ only holds near $H=0.5$. We have also introduced considerations based on the notion of a {\it time dependent Zipf law} along the signal.Comment: 24 pages, 12 figures; to appear in Int. J. Modern Phys

A Full-Potential-Linearized-Augmented-Plane-Wave Electronic Structure Study of delta-Plutonium and the (001) Surface

The electronic and geometric properties of bulk fcc delta-plutonium and the quantum size effects in the surface energies and the work functions of the (001) ultra thin films (UTF) up to 7 layers have been investigated with periodic density functional theory calculations within the full-potential linearized augmented-plane wave (FP-LAPW) approach as implemented in the WIEN2k package. Our calculated equilibrium atomic volume of 178.3 a.u.^3 and bulk modulus of 24.9 GPa at the fully relativistic level of theory, i.e. spin-polarization and spin-orbit coupling included, are in good agreement with the experimental values of 168.2 a.u.^3 and 25 GPa (593 K), respectively. The calculated equilibrium lattice constants at different levels of approximation are used in the surface properties calculations for the thin films. The surface energy is found to be rapidly converged with the semi-infinite surface energy predicted to be 0.692eV at the fully-relativistic level.Comment: 27 pages,8 figure

Evidence-based organizational change and development: is evidence-based OCD a reality or mere rhetoric?

The published version can be accessed at the following link on the publisher’s website: https://en.calameo.com/read/006426985bb96f8ce61e6This article discusses the compelling need for, and demonstrates, the significant practical 'reality' of evidence-based organizational change and development (EBOCD). It offers a summary of a previously conducted analysis that resulted in 10 validated 'original' and 10 'new' emergent common 'insights' and 'lessons learned' on the effective formulation and implementation of OCD initiatives. These were deduced from 'critical perspectives' and 'reflective case histories' of EBOCD practice offered by over 70 evidence-based organizational leaders/managers, HRD professionals and change management consultants. The article concludes with several recommendations for those engaged in OCD change agency practic

MicroRNAs in Renal Cell Carcinoma: Diagnostic Implications of Serum miR-1233 Levels

BACKGROUND: MicroRNA expression is altered in cancer cells, and microRNAs could serve as diagnostic/prognostic biomarker for cancer patients. Our study was designed to analyze circulating serum microRNAs in patients with renal cell carcinoma (RCC). METHODOLOGY/PRINCIPAL FINDINGS: We first explored microrna expression profiles in tissue and serum using taqman low density arrays in each six malignant and benign samples: Although 109 microRNAs were circulating at higher levels in cancer patients' serum, we identified only 36 microRNAs with up-regulation in RCC tissue and serum of RCC patients. Seven candidate microRNAs were selected for verification based on the finding of up-regulation in serum and tissue of RCC patients: miR-7-1*, miR-93, miR-106b*, miR-210, miR-320b, miR-1233 and miR-1290 levels in serum of healthy controls (n = 30) and RCC (n = 33) patients were determined using quantitative real-time PCR (TaqMan MicroRNA Assays). miR-1233 was increased in RCC patients, and thus validated in a multicentre cohort of 84 RCC patients and 93 healthy controls using quantitative real-time PCR (sensitivity 77.4%, specificity 37.6%, AUC 0.588). We also studied 13 samples of patients with angiomyolipoma or oncocytoma, whose serum miR-1233 levels were similar to RCC patients. Circulating microRNAs were not correlated with clinical-pathological parameters. CONCLUSIONS/SIGNIFICANCE: MicroRNA levels are distinctly increased in cancer patients, although only a small subset of circulating microRNAs has a tumor-specific origin. We identify circulating miR-1233 as a potential biomarker for RCC patients. Larger-scaled studies are warranted to fully explore the role of circulating microRNAs in RCC
