Touch in mental health nursing: an exploratory study of nurses' views and perceptions
ABSTRACT The aim of this study was to explore psychiatric nurses' perceptions of physical touch with people who experience mental health problems. A descriptive exploratory qualitative research design was used. Semi-structured interviews were carried out with 10 registered psychiatric nurses who met the inclusion criteria and were randomly selected to participate in the study. Burnard's 14 stage-by-stage process of coding and categorization was used to analyse the data. Watson distinguished between two kinds of physical touch: instrumental and expressive. The findings indicated that physical touch was used in mental health nursing; however, it was only considered to be therapeutic to clients if used judiciously, with effective interpersonal skills. The participants in this study clearly identified the need to be sensitive to both the individual client needs, and honour their personal space and cultural background. A significant issue in this study was male participants concerns that touching female clients would be misinterpreted as a sexual advance. To protect themselves, male participants used touch in a cautious and minimal manner, and only in a public space, where others could view the interaction. In the absence of research on physical touch in mental health nursing there is a need for further research to explore in detail these findings.
Conference Paper: Image segmentation through index images[Show abstract] [Hide abstract]
ABSTRACT: Image segmentation is an important preprocessing step in the applications of MPEG-4 and computer vision. It is one of major challenges in MPEG-4, since MPEG-4 is constrained by how well previous segmentation is accomplished. We propose a scheme called the SII (segmentation through index images) algorithm for image segmentation. We use the histograms of index images as the features to classify the image data into several clusters for segmentation. The 1st-moment index image is the low-resolution image that is its pixels value which is the codevector index to label all corresponding image blocks. Through the 2nd-moment index image, we identify image blocks which belong to contour or homogeneous blocks. Then, we can connect all homogeneous blocks which have the same label to define the interior of a region. The contour block is split into a smaller size and assigned to one of its neighboring regions to obtain a more accurate contour of objects. We present several experiments to show the efficiency of our SII algorithm. According to simulation results, our SII algorithm is effective for image segmentationCircuits and Systems, 2002.

ABSTRACT: Although touch is essential to nursing practice, few studies have investigated patients' preferences for how nurses should perform tasks involving touch, especially intimate touch involving private and sometimes anxiety-provoking areas of patients' bodies. Some studies suggest that patients have more concerns about intimate touch from male than female nurses. This study sought to elicit the attitudes of laypersons on intimate touch provided by nurses in general and male nurses in particular. A maximum-variation sample of 24 adults was selected and semistructured interviews were conducted in four focus groups. Interviews were recorded and transcribed; thematic analysis was performed. Four themes emerged from the interviews: "Communicate with me," "Give me choices," "Ask me about gender," and "Touch me professionally, not too fast and not too slow." Participants said they want to contribute to decisions about whether intimate touch is necessary, and when it is they want information from and rapport with their nurses. Participants varied in their responses to questions on the nurse's gender. They said they want a firm but not rough touch and for nurses to ensure their privacy. These findings suggest that nurses and other clinicians who provide intimate care should be more aware of patients' attitudes on touch. Further research on the patient's perspective is warranted.The American journal of nursing 03/2011; 111(3):24-31; quiz 32-3. DOI:10.1097/10.1097/01.NAJ.0000395237.83851.79 · 1.32 Impact Factor
