Generációs különbségek és motiváció az élelmiszeriparban

A változó gazdasági és környezeti tényezők közepette a vállalatok egyik meghatározó problémája továbbra is a munkaerő fluktuációja. A vezetők a pandémiás időszak egyik nem várt hatásaként szembesültek azzal a ténnyel, hogy a munkavállalók reakciói megváltoztak, gyakrabban és gyorsabban váltanak munkahelyet. Tanulmányunkban a generációk közötti motivációs különbségeket elemeztük. A szakirodalmi előzmények bizonyítják, hogy a generációk értékrendjében jelentős különbségek alakultak ki, amelyeket az ösztönzés és motiválás során prioritásként kell kezelni. Kutatásunkat élelmiszeripari nagyvállalatok munkavállalói körében valósítottuk meg. Az adatgyűjtés hólabda módszerrel történt, amely során 126 válaszadóból álló adatbázist alakítottunk ki. Az adatelemzés során ANOVA elemzést és LSD post hoc típusú tesztet alkalmaztunk. Eredményeinek szerint a generációk között igazolhatóak a motivációs különbségek, amelyekre a vezetőknek a motivációs stratégiájukban és gyakorlatukban építeni szükséges. A Z és Y generációs munkavállalók nehezebben tudnak azonosulni a szervezeti célokkal és nagyobb arányban terveznek munkahelyet váltani. A szervezeteknek paradigmát kell váltani a belső kommunikáció gyakorlatában, annak érdekében, hogy a vállalati „üzenetek” minden munkatárs számára célba érjen

Characterization of Mechanical Properties of Bi2Sr2CaCu2O8x Superconductor Through Scanning Electron Microscopy

Color poster with text, graphs, and photographs.We are studying Bi2Sr2Ca1Cu2Ox (Bi-2212), a high temperature superconductor. Superconductors are used in a wide variety of high field magnetic applications. Bi-2212 is the only high temperature superconductor available as a round wire that is suitable for magnets. Bi-2212 is brittle and susceptible to mechanical damage. Our research seeks to understand why this damage occurs, and how it propagates through the material.U.S. Department of Energy, Office of High Energy Physics (HEP), the Materials Science and Engineering Center at UW-Eau Claire, and the University of Wisconsin--Eau Claire Office of Research and Sponsored Programs

Effects of Overpressure Conditions on the Porosity of Bi-2212 Superconducting Wires

Color poster with text, graphs, and images.Bi2Sr2CaCu2O(8+X), abbreviated as Bi-2212, has shown promise as a high-temperature superconducting material for use in powerful magnets. Because of its brittle nature, additional study is necessary to better understand the microscopic properties of Bi-2212. One area of note is how the properties of Bi-2212 wires change after different pressure conditions are applied to them during heat treatment. This project used image analysis software and techniques to analyze SEM images of Bi-2212 wire samples that had been exposed to 10, 20, 50, and 100 bar overpressure conditions.U.S. Department of Energy, Office of High Energy Physics, award DE-FG02-13ER42036; University of Wisconsin--Eau Claire Office of Research and Sponsored Programs

Filament Damage in Bi2Sr2CaCu2O8-x (Bi-2212) Superconducting Wires Exposed by External Etching

Color poster with text, images, charts, photographs and graphs.We are studying Bi2Sr2Ca1Cu2Ox (Bi-2212): a superconducting material that is able to produce magnetic fields greater than 25 T. The study of sub-atomic particles in physics is progressing and needs higher magnetic fields for large particle accelerators. Bi-2212 is currently the only superconducting round wire capable of producing magnetic fields in excess of 20 T. Bi-2212 filaments in the silver matrix are brittle and vulnerable to damage during mechanical testing. This research seeks to understand how the damage varies under different stress and wire orientation testing conditions, and how that damage influences the wire’s electrical propertiesBlugold Commitment Differential Tuition Funds; University of Wisconsin--Eau Claire Office of Research and Sponsored Program

Bistable epigenetic states explain age-dependent decline in mesenchymal stem cell heterogeneity

The molecular mechanisms by which heterogeneity, a major characteristic of stem cells, is achieved are yet unclear. We here study the expression of the membrane stem cell antigen-1 (Sca-1) in mouse bone marrow mesenchymal stem cell (MSC) clones. We show that subpopulations with varying Sca-1 expression profiles regenerate the Sca-1 profile of the mother population within a few days. However, after extensive replication in vitro, the expression profiles shift to lower values and the regeneration time increases. Study of the promoter of Ly6a unravels that the expression level of Sca-1 is related to the promoter occupancy by the activating histone mark H3K4me3. We demonstrate that these findings can be consistently explained by a computational model that considers positive feedback between promoter H3K4me3 modification and gene transcription. This feedback implicates bistable epigenetic states which the cells occupy with an age-dependent frequency due to persistent histone (de-)modification. Our results provide evidence that MSC heterogeneity, and presumably that of other stem cells, is associated with bistable epigenetic states and suggest that MSCs are subject to permanent state fluctuation
