Human Resources (HR) in the Age of Technology: An Examination of the Relationship Between HR and Technology

Technology helps the Human Resources (HR) department drive for strategic relevance. These two departments are successfully collaborating on major projects in such business-critical areas as e-recruiting, self-service, training, compensation and talent management. Technology is critical in helping increase efficiency, increase attraction and retention, reduce administration and cut costs. In recent years, HR information systems (HRIS) have become more important than ever, this time as an essential part of a company's information security and knowledge fields. Ill-suited benefits and disorganized resources are history; now is the time for customized, dynamic plans and connected systems. Employees will appreciate the HRIS, business will benefit from the HRIS and the HR department will no longer have to be the ugly duckling of the company.

Electrochemical performance of carbon gels with variable surface chemistry and physics

This study describes the electrochemical characterization of N-doped carbon xerogels in the form of microspheres and of carbon aerogels with varied porosities and surface oxygen complexes. The interfacial capacitance of N-doped carbon xerogels decreased with increased micropore surface area as determined by N2 adsorption at −196 °C. The interfacial capacitance showed a good correlation with the areal NXPS concentration, and the best correlation with the areal concentration of pyrrolic or pyridonic nitrogen functionalities. The gravimetric capacitance decreased with greater xerogel microsphere diameter. The interfacial capacitance of carbon aerogels increased with higher percentage of porosity as determined from particle and true densities. The interfacial capacitance showed a linear relationship with the areal oxygen concentration and with the areal concentrations of CO- and CO2-evolving groups.

Student lectures notes on chemistry and materia medica, and medical recipes, of Lyman Spalding, 1795-1799 (inclusive)

Contains notes taken by Harvard student Lyman Spalding during eleven chemistry lectures delivered by Harvard Professor Aaron Dexter (1750-1829) in the fall of 1795 and recipes prepared and used by Spalding in his medical practice in 1797. The recipes include elixir vitriol, containing liquor, Jamaica pepper, cinnamon, and ginger, and an electuary for a cough, containing oxymel squills (sea onion in honey), licorice, antimonium tartaricum potash (a compound of the chemical element antimony and a potassium-containing salt), and opium. The volume also contains writings about chemistry by Spalding, some of which appear transcribed from published sources, in undated entries, and a diary entry from 1799 regarding an experiment with water.
