How to manage generations? An Approach based on the Quality of Work Life
The objectives of this research are to examine whether there are significant differences in the perception of quality of work life among employees of three generational cohorts (i.e., Baby Boomers, Generation Xers and Millennials) and to propose some strategies from HRM in order to manage these differences. We used survey data collected from 522 employees of the logistic sector in Colombia and conducted internal consistency analysis, correlation analyses and one-way ANOVA. Results of ANOVA indicate that variables of quality of work life significantly differ depending on the generational membership of the employees. For example, Millennials were found to be a more distinct cohort from Gen Xers and Baby Boomers in terms of their relationship between promotion and career. However, the results suggest that employees in the older generations are likely to be more dedicated to, engrossed in, and even vigorous at work. For future studies, we recommend discussing how the knowledge on each generation in the workplace can inform specific HRM practices, such as how to train each generation effectively or to encourage each generation to improve work performance.

Preference for Risk Management Information Sources: Implications for Extension and Outreach Programming
This article examines farmers’ preferences for various risk management information sources. Our results suggest that information from risk management experts, in-depth materials studied on their own, and popular press outlets tend to be preferred and are ranked highly by producers. Using a regression model to investigate farmer/farm attributes that affect preference for a particular risk management information source, we find that younger farmers with college education, higher leverage, assets greater than $1 million, risk-loving attitudes, and who have used professional services (marketing consultants) tend to prefer information from risk management experts, the Internet, and marketing clubs/other producers. On the other hand, producers who prefer self-study of educational materials and popular press information sources tend to be younger, with lower leverage levels, and have used fewer professional services.crop insurance, extension, information sources, outreach, risk management, Risk and Uncertainty,
Microscopic and Macroscopic Signatures of Antiferromagnetic Domain Walls
Magnetotransport measurements on small single crystals of Cr, the elemental
antiferromagnet, reveal the hysteretic thermodynamics of the domain structure.
The temperature dependence of the transport coefficients is directly correlated
with the real-space evolution of the domain configuration as recorded by x-ray
microprobe imaging, revealing the effect of antiferromagnetic domain walls on
electron transport. A single antiferromagnetic domain wall interface resistance
is deduced to be of order at a
temperature of 100 K.Comment: 3 color figure
Study of multi black hole and ring singularity apparent horizons
We study critical black hole separations for the formation of a common
apparent horizon in systems of - black holes in a time symmetric
configuration. We study in detail the aligned equal mass cases for ,
and relate them to the unequal mass binary black hole case. We then study the
apparent horizon of the time symmetric initial geometry of a ring singularity
of different radii. The apparent horizon is used as indicative of the location
of the event horizon in an effort to predict a critical ring radius that would
generate an event horizon of toroidal topology. We found that a good estimate
for this ring critical radius is . We briefly discuss the
connection of this two cases through a discrete black hole 'necklace'
configuration.Comment: 31 pages, 21 figure
Mercury removal in wastewater by iron oxide nanoparticles
Mercury is one of the persistent pollutants in wastewater; it is becoming a severe environmental and public health problem, this is why nowadays its removal is an obligation. Iron oxide nanoparticles are receiving much attention due to their properties, such as: great biocompatibility, ease of separation, high relation of surface-area to volume, surface modifiability, reusability, excellent magnetic properties and relative low cost. In this experiment, Fe3O4 and γ-Fe2O3 nanoparticles were synthesized using iron salts and NaOH as precipitation agents, and Aloe Vera as stabilizing agent; then these nanoparticles were characterized by three different measurements: first, using a Zetasizer Nano ZS for their size estimation, secondly UV-visible spectroscopy which showed the existence of resonance of plasmon at λmax∼360 nm, and lastly by Scanning Electron Microscopy (SEM) to determine nanoparticles form. The results of this characterization showed that the obtained Iron oxides nanoparticles have a narrow size distribution (∼100nm). Mercury removal of 70% approximately was confirmed by atomic absorption spectroscopy measurements
La producción limpia en el régimen jurídico ambiental del Ecuador
This work is born of the need for consistent legislation regarding production cleaner, identifying alternatives to solve and prevent the consequences of an increasingly polluted environment. This study aims to make a proposal to allow our laws to exercise effective control over the industry to identify production parallel methods that avoid the most pollution.El presente trabajo investigativo nace de la necesidad de una legislación coherente respecto a una producción limpia, donde se identifiquen alternativas para solucionar
y prevenir las consecuencias de un ambiente cada vez mas contaminado. Este estudio busca hacer una propuesta que permita a nuestra legislación ejercer un control efectivo sobre la industria, para que su producción identifique métodos paralelos que eviten al máximo la contaminación ambiental. El objetivo implica fortalecer el ordenamiento jurídico de tal forma que las sanciones no solamente afecten a quien contamine indiscriminadamente, sino a las autoridades que permiten hacerlo
