1,1-Diethyl-3-(4-meth­oxy­benzo­yl)thio­urea

In the title compound, C13H18N2O2S, the 4-meth­oxy­benzoyl fragment is approximately planar [maximum deviation = 0.057 (2) Å] and twisted relative to the thio­amide fragment, forming a dihedral angle of 86.62 (6)°. The two Csp 2—Nsp 2 bonds in the thio­urea unit differ significantly in length [1.327 (2) and 1.431 (2) Å]. In the crystal, N—H⋯O hydrogen bonds link the mol­ecules into chains parallel to [010]

N-(Pyrrolidin-1-ylcarbothio­yl)benzamide

In the title compound, C12H14N2OS, the pyrrolidine ring adopts an envelope conformation with the C atom at the 3-position as the flap and makes a dihedral angle of 65.80 (9)° with the benzene ring. In the crystal, N—H⋯O hydrogen bonds join c-glide related mol­ecules into chains extended along [001] that are further connected into (100) layers via C—H⋯O inter­actions

Organizational Information Security: Strategies to Minimize Workplace Cyberloafing for Increased Productivity

Productivity loss occurs in organizations that experience high levels of personal Internet use by employees on company time, which includes employees using smartphones to surf without needing the firm\u27s Internet connection. The purpose of this qualitative phenomenological study was to explore reliable ways for organizational leaders to monitor or limit their employees\u27 use of smartphone technology for personal use (cyberloafing) while on the job to minimize wasted work time. Social cognitive theory, which includes an emphasis on human behavioral changes based upon the environment, people, and behavior, served as the conceptual framework. The general research question was as follows: How can managers minimize wasted work time by limiting the personal Internet activity of employees who use personal mobile devices while on the job. Data collection involved gathering information from interviews with 20 frontline supervisors, human resource managers, and information technology managers and specialists in 2 U.S. industries: education and telecommunications. Data analysis included examining word frequencies, keyword coding, and identifying themes. Four management themes emerged: create mobile device usage policy, enforce monitoring technology, create a deterrence strategy, and customize monitoring and tracking technology. This study may be important because the analysis revealed effective ways to prevent or minimize employees from Internet surfing and wasting time at work. The findings could lead to positive social change through increased employee productivity and responsibility by providing managers with information to control or limit cyberloafing activities and by fostering an increased commitment to comply with an organization\u27s Internet use policy

Two-Stage LASSO ADMM Signal Detection Algorithm For Large Scale MIMO

This paper explores the benefit of using some of the machine learning techniques and Big data optimization tools in approximating maximum likelihood (ML) detection of Large Scale MIMO systems. First, large scale MIMO detection problem is formulated as a LASSO (Least Absolute Shrinkage and Selection Operator) optimization problem. Then, Alternating Direction Method of Multipliers (ADMM) is considered in solving this problem. The choice of ADMM is motivated by its ability of solving convex optimization problems by breaking them into smaller sub-problems, each of which are then easier to handle. Further improvement is obtained using two stages of LASSO with interference cancellation from the first stage. The proposed algorithm is investigated at various modulation techniques with different number of antennas. It is also compared with widely used algorithms in this field. Simulation results demonstrate the efficacy of the proposed algorithm for both uncoded and coded cases.Comment: 5 pages, 4 figure

Resistance to the two-spotted spider mite, Tetranychus urticae (Koch), in New Guinea Impatiens

Twenty-seven Impatiens lines were screened and scored for resistance to the two-spotted spider mite, tested for leaf cuticle amount, crossed, and selfed. Progenies of successful matings were subjected to feeding preference and score rating tests. Seventeen lines from the parents and their progenies were selected and tested for oviposition, life cycle of the pest, feeding preference, leaf pH preference, and for size of eggs, females, and males of the mites;Considerable differences were found among these lines in all tests except the reciprocal hybrid evaluation. Leaf cuticle appeared to have some influence on development of the mite population;The resistance to the mites in Impatiens does not seem to be related to a single mechanism but to many mechanisms, and the genetic control of resistance is no doubt complex;Attention in future studies should be focused on the twin lines, \u277729-8\u27 and \u277729-9\u27, as sources of genes for resistance to the two-spotted spider mite
