Stalking of Healthcare Professionals by Their Clients: The Prevalence, Motivation, and Effect

It is proposed that healthcare professionals are prone to be stalked by their patients, but many feel ashamed to talk about it, believing that they might have done something to warrant the stalking. We undertook a rigorous review of the literature with the primitive goal of highlighting noteworthy issues on the stalking of healthcare professionals and psychologists by their patients. Databases such as PubMed and Google Scholar were searched to collate articles and studies on the topic with the keywords “stalker, stalking, assaults, aggression, and physicians”. From the review, the prevalence rate of stalking healthcare professionals ranged between 6% - 53%. This huge variation was largely due to the inconsistencies in the definition of what constituted stalking. The common motives of stalkers were largely due to erotomania or misguided expectation and a sense of resentment due to service dissatisfaction. Finally, it was apparently right to conclude that, medical doctors or healthcare professionals are at risk of being stalked on the grounds of service dissatisfaction, and mismanagement of treatment processes resulting in physical or perceived client injuries. Whereas psychologists and other psychiatrists are more prone to be stalked due to erotomaniac reasons.

Secure Video Streaming with Lightweight Cipher PRESENT in an SDN Testbed

The combination of traditional processors and Field Programmable Gate Arrays(FPGA)is shaping the future networking platform for intensive computation in resource-constrained networks and devices.These networks present two key challenges of security and resource limitations.Lightweight ciphers are suitable to provide data security in such constrained environments.Implementing the lightweight PRESENT encryption algorithm in a reconfigurable platform(FPGAs)can offer secure communication service and flexibility.This paper presents hardware acceleration of security primitives in SDN using NETFPGA-10G.We implement an efficient design of the PRESENT algorithm for faster,smaller and lower power consumption hardware circuit using Verilog.We evaluate the performance of the hardware and software implementations of PRESENT.Experimental results prove that the proposed hardware design is a viable option for use in resource constrained devices in future networks and their applications.

ORDERED ANALYTIC REPRESENTATION OF PDES BY HAMILTONIAN CANONICAL SYSTEM

Based on the method of symplectic geometry and variational calculation,the method for some PDEs to be ordered and analytically represented by Hamiltonian canonical system is discussed.Meanwhile some related necessary and sufficient conditions are obtained

A functional presentation of Pi calculus

From the very beginning process algebra introduced the dichotomy between channels and processes. This dichotomy prevails in all present process calculi. The situation is in contrast to that withlambda calculus which has only one class of entities-the lambda terms. We introduce in this papera process calculus called Lamp in which channels are process names. The language is more uniform than existing process calculi in two aspects: First it has a unified treatment of channels and processes.There is only one class of syntactical entities-processes. Second it has a unified presentation ofboth first order and higher order process calculi. The language is functional in the sense that lambda calculus is functional. Two bisimulation equivalences, barbed and closed bisimilarities, are proved to coincide.A natural translation from Pi calculus to Lamp is shown to preserve both operational and algebraic semantics. The relationship between lazy lambda calculus and Lamp is discussed.
