This one-year follow-up study determined the incidence and risk factors of workplace violence against nursing staff in a psychiatric hospital. The cohort members had a website to report events whenever they came across violence. A total of 971 events were reported. The incidence rates of physical violence, verbal abuse, bullying/mobbing, sexual harassment,(More)
In this work, a two-phase genetic local search algorithm is proposed to train the connection weights of the feedforward neural networks. Various evolutionary algorithms including evolution strategies, evolutionary programming, and genetic algorithms had been proposed to train the weights and/or architectures of neural networks. But, most of them did not(More)
In this work, the systematic trajectory search algorithm (STSA) is proposed to train the connection weights of the feedforward neural networks. The STSA utilizes the orthogonal array (OA) to uniformly generate the initial population in order to globally explore the solution space, then it applies a novel trajectory search method that can exploit the(More)

To the Editor: In psychiatry, interview skills are considered core abilities [1], especially in managing difficult situations in psychiatric wards. Research has found that poor doctor-patient interviews led to increased errors and noncompliance in medication-taking behavior. Furthermore, psychotic patients, owing to a lack of insight into their own(More)
OBJECTIVES The aim of this study was to determine the validity and reliability of the Taiwanese Mandarin version of the Personal and Social Performance scale (TMV-PSP) using a structured interview and a computerized scoring calculator. METHODS In total, 655 patients with schizophrenia or schizoaffective disorder were assessed with the TMV-PSP, the(More)
In this paper, an improved version of the systematic trajectory search algorithm (STSA) is proposed to train the connection weights of the generalized feedforward neural networks. By generalized feedforward neural networks, we mean that links are not restricted to just going from one layer to the next layer. The STSA utilizes the orthogonal array (OA) to(More)
