Individual trophic specialization in juvenile European seabass: implications for the management of a commercially important species
No full textIndividual differences in diet can play an important role defining a population's ecological niche and its role within food webs and habitats, but individual trophic specialization is rarely considered in a fisheries context. Stocks of European seabass, Dicentrarchus labrax, have declined in recent years, and policy has focused on managing fishing effort. Inshore nursery grounds represent a critical habitat in terms of recruitment to standing stocks, and improved understanding of the ecology of juvenile seabass at the level of the individual may assist the development of management strategies aimed at maximizing their survival and growth. We quantified levels of individual trophic specialization in juvenile seabass using stomach contents and stable isotope analyses at a monthly resolution over an annual cycle. We found significant, seasonally varying levels of individual specialization in stomach contents, with reduced specialization observed in the spring. This was corroborated by stable isotope analyses, where isotopic variance among seabass individuals was significantly higher compared to that in two other concurrently sampled, sympatric bentho-pelagic predators. Our findings suggest that juvenile seabass form trophic-generalist populations composed of specialized individuals. Considering variation in individual behaviours may improve management strategies aimed at protecting the vulnerable life stages of this commercially important species

Servant and Steward: The Steward Leader Model for Unleashing Human Potential
No full textExecutive Summary The mandate for business leaders to consistently predict and achieve economic success reverberates throughout American society. Many leaders who wish to practice transformational leadership are faced with the dilemma of implementing command and control, productivity driven leadership techniques to achieve bottom-line results. These management practices were developed during a time when the workplace was perceived as a place of cause and effect, action and reaction. The ideal employee was one whose actions matched the consistency and reliability of a machine. This focus on Frederick Taylor\u27s management techniques, in the workplace and in many MBA programs, may in fact undermine the economic success of organizations. The opportunities for American businesses in the 21st century have to do with developing our greatest assets, which are our emotional intelligence and our ability to take responsibility and make innovative decisions. The author of this article believes that a deeper examination of the steward leader model offers business leaders an opportunity to integrate transformational leadership values with economic values in an organization\u27s operating model. The approach is centered on the concept of stewardship. In this article, the author outlines the elements of a steward leader model that emerged as a result of conducting a review of the literature and an informal field interview with a steward leader
Who Wants To Be A Woodland Steward? Understanding Barriers to Forestland Stewardship in Minnesota
No full textA third of the nation’s forestland is owned and stewarded by family forest owners (Butler et al. 2021). These private landowners (woodland stewards) value them primarily due to the beauty, natural values, and wildlife habitat they provide. In Minnesota, 102,000 woodland stewards own and manage over five million acres of forestland in the state (USDA Forest Service, 2021). While private forestland in Minnesota is diverse in terms of the composition and characteristics of the forest, the demographics of woodland stewards are not. The objectives of this project were to (1) interview Minnesota residents that have been historically excluded from owning forestland within the State to understand their motivations and barriers to stewarding, purchasing, owning, and managing land and (2) build Extension’s repertoire of woodland steward resources that are more culturally-relevant.This project was supported through a University of Minnesota Institute on the Environment Mini Grant, Project MF-0003-20.

Simulation of Uniaxial Compression for Flexible Fibers of Wheat Straw Using the Discrete Element Method
No full textTo accurately simulate a discrete element method (DEM) model, the material properties must be calibrated to reproduce bulk material behavior. In this study, a method was developed to calibrate DEM parameters for bulk fibrous materials using uniaxial compression. Wheat straw was cut to 100.2 mm lengths. A 227 mm diameter cylindrical container was loosely filled with the cut straw. The material was pre-compressed to 1 kPa. A plunger (50, 150, or 225 mm diameter) was then lowered onto the compressed straw at a rate of 15 mm s-1. This experimental procedure was simulated using a DEM model for different material properties to generate a simulated design of experiment (DOE). The simulated plunger had a travel rate of 40 mm s-1. The contact Young‘s modulus, bond Young‘s modulus, and particle-to-particle friction DEM parameters were found to be statistically significant in the prediction of normal forces on the plunger in the uniaxial compression test. The DEM calibration procedure was used to approximate the mean laboratory results of wheat straw compression with root mean square (RMS) percent errors of 3.77%, 3.02%, and 13.90% for the 50, 150, and 225 mm plungers, respectively.This article is published as Schramm, Matthew W., Mehari Z.

Jo Matthew, Detroit Playboy Club Bunny
No full textMrs. Jo Matthew, a 26-year-old Detroit Playboy Club Bunny who was turned out to pasture three years ago because she allegedly had lost the Bunny image, has won back her job and more than $15,000 in back pay. A Roseville, Mich., labor arbitrator ruled 10/20 that Bunny Jo (who posed for photographers on a bearskin rug with a union strike sign as a background during the news conference) was fired because she was a gung-ho shop steward for her union, Local 705 of the Hotel and Restaurant Employees.https://digitalcommons.chapman.edu/upi_misc/1023/thumbnail.jp

No full textA Human Capital-Based Theory of Post-Marital Residence Rules
No full textIn pre-modern societies the residence of a newly-wedded couple is often decided by custom. While researchers have analyzed factors leading to particular post-marital residence patterns, no one has explained why a society should have a customary rule in the first place. Our theory stems from contracting problems created by the nature of pre-marriage human capital investments. We argue that a fixed post-marital residence rule may solve a hold-up problem by specifying marriage terms and limiting possibilities for renegotiation; the trade-off is the rule may prohibit beneficial renegotiation of post-marital location. We compare alternative residence rules (or lack thereof) under different degrees of location specificity of human capital and environmental uncertainty. We apply our theoretical results to Murdock's (1967) 862-society data set, augmented with climate data. We find some predictive ability in variables related to outside options, control over the environment, and potential degree of social control.
