Impact of ITS in estimation of traffic congestion level of an urban corridor
Full text linkThis study attempts to make use of traffic behaviour on the aggregate level to estimate congestion on urban arterial and sub-arterial roads of a city exhibiting heterogeneous traffic conditions by breaking the route into independent segments and approximating the origin-destination based traffic flow behaviour of the segments. The expected travel time in making a trip is modelled against sectional traffic characteristics (flow and speed) at origin and destination points of road segments, and roadway and segment traffic characteristics such as diversion routes are also tried in accounting for travel time. Predicted travel time is then used along with free flow time to determine the state of congestion on the segments using a congestion index (CI). A development of this kind may help in understanding traffic and congestion behaviour practically using easily accessible inputs, limited only to the nodes, and help in improving road network planning and management
The Process of Identity Adaptation （ Oriai ） in Community-Dwelling People with Schizophrenia ï¼ Results from Content Analyses and Text Mining ï¼
Full text linkThis study aimed to further elucidate the process of identity adaptation in people with schizophrenia by talking to them about their illness. Semi-structured interviews were conducted with nine community-dwelling people with schizophrenia. Analysis was performed using Krippendorf’s approach, and Text Mining. Eleven content categories were derived: “illness acceptanceâ€, “self-controlâ€, “help from familyâ€, “help from friendsâ€, “help from doctors or nursesâ€, “modifying thinkingâ€, “social roles and activitiesâ€, “worthwhile workâ€, “enjoyment of lifeâ€, “being happyâ€, and “being freeâ€. Participants with schizophrenia were found to attain “illness acceptance†based on “help from familyâ€, “help from friendsâ€, and “help from doctors and nursesâ€. Text mining results is 400 keywords were identified. The top 5 in order of importance and frequency were: “omou†(feel/think), “naru†(become), “iu†(say), “suru†(do), and “kusuri†(medication).As a result of an interactive process surrounding the concepts of “illness acceptanceâ€, “self-control†and “modifying thinking†the participants sought out “social roles and activities†and “worthwhile work†to acquire a social identity. Thus, it was found that the participants felt they “enjoyed life and were happy†and “they were freeâ€, because they were productive members of society
A review of flexible management for patients with Congestive Cardiac Failure (CCF): The implementation of post discharge Rapid Response Teams (RRTs)
Full text linkHospitalized patients with Congestive Cardiac Failure (CCF) often experience an acute decline in their conditions post- discharge usually preceded by changes in their vital signs (for eg. respiratory rate, heart rate, blood pressure and temperature). Should these subtle changes go unrecognized, can have serious implications for patient mortality and morbidity. However, as this article outlines, implications such as these may be prevented by interventions being made by specialist practitioners known as Rapid Response Teams (RRTs). The role of such teams in the postdischarge period is to promptly identify patients at risk of further clinical decline and initiate appropriate responses to prevent serious adverse events. The aim of this article is to briefly review the management of patients with CCF in the hospital and propose the initiation of RRTs post-discharge for CCF patients in Singapore. Moreover, the article proposes that such teams should be implemented in Singapore as a positive contribution to the care and treatment of people with CCF. RRTs were conceptualized as a consultative service to bring critical care expertise to the management of patients with CCF following discharge from the hospital. This article considers the challenges and barriers to the implementation of RRTs in a Singaporean context by using SWOT analysis to consider the potential in terms of the both the benefits and the difficulties that such an initiative can produce
A survey: Knowledge about breast cancer and health beliefs towards screening practice among menopausal and postmenopausal women
Full text linkBreast cancer is a major health problem with high mortality in women worldwide and has become the third most prevalent disease among women in Hong Kong. Knowledge about breast cancer is closely related to health beliefs towards screening practices for breast cancer. This study examined knowledge about breast cancer and breast cancer screening (BCS) beliefs among menopausal and postmenopausal women. A total of 213 eligible women, mostly aged 55 to 60, who were housewives or retired and were educated at secondary school level or above, were selected. A survey using the Chinese Breast Cancer Screening Beliefs (CBCSB) questionnaire was conducted. The results revealed that menopausal and postmenopausal women had better health beliefs towards breast cancer screening practices. Education was found to be positively associated with attitudes of BCS health beliefs. It indicates that education can affect attitudes towards breast cancer screening practice. Most of the women presented inadequate knowledge and they wished to receive more information about breast cancer although they were well-educated. It is important to note that knowledge about breast cancer cannot be effectively delivered to the at-risk women. In addition, menopausal and postmenopausal women can be more likely to seek more information about the effectiveness and side effects of the medication for breast cancer. Therefore, treatment about effectiveness, side effects, and prices ought to be included in current educational programs and healthcare services in the promotion schemes. Healthcare professionals should also pay more attention to better BCS practices in community-based educational programs with information on preventive measures for breast cancer to menopausal and postmenopausal women, particularly to those in lower socioeconomic classes
A cross-sectional study: Collaborative learning approach enhances learning attitudes of undergraduate nursing students
Full text linkCollaborative learning approach is an effective teaching method to receive optimal achievement in knowledge and skills. Since nursing is a profession that emphasizes multidisciplinary collaboration, collaborative learning approach has been commonly adopted in current nursing education to maximize students’ learning and develop their collaborative attributes. It is important that learning attitudes shall be positive to reach benefits of collaborative learning. This study was to examine how learning attitudes of nursing undergraduate students in respond to collaborative learning approach. The results may help nursing school administrators design more appropriate learning activities and give educators insights to implement collaborative learning approach more effectively
Experiences of flipping an online classroom An appraisal using Community of Inquiry Framework
Full text linkTechnological developments in the recent times have changed the face and attributes of higher education. Online education, with an emphasis on technology augmented learning strategies, exerts unprecedented pressure on educators to adapt these changes. The increasing focus on cost effectiveness in the sector adds to this challenge. Hence, there is demand on educators to devise innovative instructional methods which are flexible, user-friendly, empowering and student-centred. A rational process in response to such demands and challenges would involve collaboration and sharing of learning-teaching practices among educators.This paper shares and explores the experiences of flipping an online classroom with a large cohort of externally enrolled, Undergraduate Nursing and Midwifery students in a regional Australian university. The design, implementation, and outcome of this active learning strategy are examined using the theoretical framework, Community of Inquiry by Garrison, Anderson, and Archer [1]. The students’ readiness engage in the task, in a student-centred pedagogy which reinforced higher order thinking was the key to this successfully flipped task
Parental decision about human papillomavirus vaccination for their daughters
Full text linkBackground: Human papillomavirus (HPV) infection is a sexually transmitted infection common in teenagers and adults in their early 20s. Some types of HPV are associated with 90% of cervical cancer around the world. The risk of HPV infection in women can be reduced by giving HPV vaccine to girls beginning at the age of 9, as recommended by Centers for Disease Control and Prevention (CDC). For children and young adolescents, parental decision on HPV vaccination is crucial for the uptake of HPV vaccine rate. This study explored the factors influencing parental decisions on HPV vaccination for their daughters. Methods: A cross-sectional survey was conducted between February and March 2017. Data were collected from parents of girls aged 9 to 17 (n=420, 100 % response rate) in Hong Kong. A validated 27-item questionnaire was used to elicit parents’ knowledge on HPV and HPV vaccine, barriers to HPV vaccination, and willingness toward vaccinating their daughter(s). Results: Only 59.6% of respondents were aware of the HPV vaccine before this study. Among the parents who were aware of the vaccine, around 32% had already vaccinated their daughters. Majority (83%) of the parents had heard of HPV, but the knowledge levels were poor (70% scored below average). The reasons parents did not vaccinate their daughters were fear of the side-effects of the vaccine (85.7%) and feared the vaccine would affect the immune system of their daughters (38.5%); around 18% believed that HPV vaccination would encourage early sexual activity or promiscuity. More than half of the respondents (69.7%) were willing to vaccine their daughter(s). Conclusions: Given the evidence of suboptimal awareness about HPV vaccination, education and promotional strategies should be enhanced. Interventions should address parental concerns about the misconceptions between vaccination and early sexual activity and promiscuity
Undoing Chinese Privilege in Singapore through Reading with the Other
Full text linkContemporary cultural studies in USA have seen the rise of whiteness studies that seek to understand the nature of white privilege and its conditions of possibility. Despite calls from several activists and academics to look at how this resonates and yet deviates from Chinese privilege in Singapore, they have not gained much traction in local discussions in and outside the academia. Thus in this paper, I come as a subject, conditioned by middle-class Chinese heteronormative patriarchal privilege in Singapore but yet belonging to what is perceived to be a western religion, Christianity, to engage with the question of ‘Chinese Privilege’ through a contrapuntal reading of a story from the Bible in the book of Daniel, chapter 1 with Alfian Sa’at’s anthology, Malay Sketches (2012). The aim of this paper is to seek the undoing of my Chinese privilege while attempting to avoid the narcissism of navel-gazing in order to think deeper what it means following Gayatri Spivak, to ‘learn to learn from below’. I achieve this through surfacing the struggle of hiddenness in the story of Daniel by inflecting it through experiences of Malay marginalisation so as to alienate a text that is often (mis)used to reinforce epistemologies of ignorance to Chinese privilege
HadoopSec: Sensitivity-aware Secure Data Placement Strategy for Big Data/Hadoop Platform using Prescriptive Analytics
No full textHadoop has become one of the key player in offering data analytics and data processing support for any organization that handles different shades of data management. Considering the current security offerings of Hadoop, companies are concerned of building a single large cluster and onboarding multiple projects on to the same common Hadoop cluster. Security vulnerability and privacy invasion due to malicious attackers or inner users are the main argument points in any Hadoop implementation. In particular, various types of security vulnerability occur due to the mode of data placement in Hadoop Cluster. When sensitive information is accessed by an unauthorized user or misused by an authorized person, they can compromise privacy. In this paper, we intend to address the approach of data placement across distributed DataNodes in a secure way by considering the sensitivity and security of the underlying data. Our data placement strategy aims to adaptively distribute the data across the cluster using advanced machine learning techniques to realize a more secured data/infrastructure. The data placement strategy discussed in this paper is highly extensible and scalable to suit different sort of sensitivity/security requirement
The psychometric properties of dementia knowledge scales: a systematic review
Full text linkDementia prevalence is accelerating internationally commensurate with population aging causing suffering from families as well as society burden because it is generally met with misunderstanding, fear, and stigma. Therefore, it is hoped that efforts to increase awareness, reduce stigma, and clarify misunderstandings of the illness can enable early detection of dementia. There are many different tests that were used to assess dementia knowledge however the use of inferior methods could account for some inconsistent findings related to dementia knowledge. It is important to define robustness of the psychometric properties of dementia knowledge tools. The aim of this study is to provide a systematic overview of what is known from previous research on assessing the reliability and validity of psychometric properties of dementia knowledge scales. A systematic literature search (2009 - 2017) was performed using the electronic databases PubMed, Web of science and Google scholar in English and Vietnamese. References and citations were tracked to identify additional, relevant studies basing on study eligibility criteria and excluded criteria. Five original studies were recruited from 562 studies in the selected databases for analyzing of the measurement properties of dementia knowledge scales. Quality judgment criteria were formulated and used to evaluate the psychometric aspects of the scales. Results: This systematic review revealed 4 dementia knowledge scales (ADKS, DKAS, DK-20, DKAT2) in 5 selected researches. Our findings (based on quality judgment criteria relating to validity, reliability, feasibility) demonstrate that ADKS, DKAS show good psychometric qualities, ranging from 15-17 score of psychometric qualities of dementia knowledge scale. The last two (DK-20 and DKAT2) scored 11 and 13 points of a maximum quality score of 20, respectively, so their psychometric quality can be regarded as moderate. Therefore, these tools await confirmation of various aspects of their psychometric properties. Conclusion: Based on the psychometric qualities, we concluded that ADKS and DKAS are the appropriate scales currently available. Further research should focus on improving these scales by further testing their validity, reliability, and utility.  Â
