    Stigma is a major barrier to mental health service utilization and treatment adherence. Effective anti-stigma interventions have been identified using predominantly Caucasian research subjects. Participation in research studies by other racial and ethnic groups has been limited. This pilot study examined the external reliability of Wood and Wahl’s (2006) study, which examined the effectiveness of an anti-stigma program, In Our Own Voice (IOOV), by the National Alliance on Mental Illness (NAMI) among predominantly Caucasian undergraduate students. An older Korean ESOL group in a Korean community center in New York City (N = 20) served as the participants in this study and attended either a culturally adapted older version (N = 8) or a culturally adapted updated version (N = 12) of the IOOV program. Participants completed four pre-test measures of knowledge and attitudes that targeted public stigma and repeated the same four measures at post-test. Lastly, the participants provided feedback about the IOOV program. Participants who attended the older IOOV program indicated greater willingness to interact with individuals with a mental illness over time while participants who attended the updated IOOV program reported decreased willingness to interact with individuals with a mental illness over time. Improvement in knowledge and willingness to seek professional help were found in both groups. Compared to the college sample in Wood and Wahl’s study, participants in the ESOL class obtained lower means across measures. Follow-up studies need to be conducted to increase the effect size and reliability of this pilot study’s findings

    A Comparison Of Usual t-Test Statistic and Modified t-Test Statistics on Skewed Distribution Functions

    When the sample size n is small, the random variable T= √n(\overline{X} – μ)/S is said to follow a central t distribution with degrees of freedom (n – 1), where \overline{X} is the sample mean and S is the sample standard deviation, provided that the data X ~ N (μ, σ2). The random variable T can be used as a test statistic to hypothesize the population mean μ. Some argue that the t-test statistic is robust against the normality of the distribution and claim that the normality assumption is not necessary. In this article we will use simulation to study whether the t-test is really robust if the population distribution is not normally distributed. In particular, we will study how the skewness of a probability distribution will affect the confidence interval as well as the t-test statistic

    We begin the thesis by giving an intuitive introduction to calculus on mani- folds for the non-mathematician. We then give a semi-intuitive description on Ricci curvature for the non-geometer. We give a description of the N-Bakry- Émery Ricci curvature and the N-quasi Einstein metric. The main results in this thesis are related to the N-Bakry-Émery Ricci curvature and the N-quasi Einstein metric. Our first set of main results are as follows. We generalize topological results known for noncompact manifolds with nonnegative Ricci curvature to spaces with nonnegative N-Bakry Émery Ricci curvature. We study the Splitting Theorem and a property called the geodesic loops to infinity property in relation to spaces with nonnegative N-Bakry Émery Ricci Curvature. In addition, we show that if M^n is a complete, noncompact Riemannian manifold with non- negative N-Bakry Émery Ricci curvature where N \u3e n, then Hn-1(M,Z) is 0. For our second set of main results, we classify the compact locally homogeneous non-gradient N-quasi Einstein 3-manifolds. Along the way, we also prove that given a compact quotient of a Lie group of any dimension that is N-quasi Einstein, the potential vector field X must be left invariant and Killing. We also classify the nontrivial N-quasi Einstein metrics that are a compact quotient of be the product of two Einstein metrics. We also show that S^1 is the only compact manifold of any dimension which admits a metric which is nontrivially N-quasi Einstein and Einstein

    Writing generator: a study on the use of Transitional Markers in Academic Writing / Alice Shanthi... [et al.]

    Coherence and cohesion are often considered an abstract and difficult area in the teaching of writing. The present study attempts to identify the categories of transitional markers (TM) used by students who have been taught using the Cycle 1 Writing Generator Beta 1.0 developed by the researchers in a writing class, and whether students are able to retain the skills of using TMs effectively in later writing. The Writing Generator is a Microsoft word tool that prompt student to choose from a list the formulaic phrases and expressions when they write expository essays. Using descriptive statistics, it was revealed that transitional markers were used by these students in their pre-test, post-test and also delayed post-test. The findings show a significant difference in the frequency of TMs used in the pre- test and post-test (p=.000). Though students failed to retain aspects of TMs in delayed post-test without the use of Writing Generator, the t-test found no significant difference between the post-test and delayed post-test (p=.302). The result indicates that the Writing Generator is able to condition students to choose TMs that bring about unity in their writing even they do not use the tool. The study indicates that the Cycle 1 Writing Generator Beta 1.0 could be developed further with extra features for Cycle 2 Beta 2.0 that could facilitate students’ uptake of academic writing skills more effectively among students

    Urban morphology and syntactic structure: A discussion of the relationship of block size to street integration in some settlements in the Provence

    Get PDF
    The paper discusses the relationship between the syntax of street networks and the differentiation of the size of urban blocks in a sample of small towns and settlements. he argument is in four parts. In the first part it is demonstrated, through design games, that the differentiation of streets by integration is linked to the differentiation of blocks by size. In the second part, it is shown that in a small sample of towns in the Provence, small blocks are not associated with more integrated streets but are distributed throughout the street network. The demonstration is based on an original method for studying the block size in relation to street integration. In the third part, the historic evolution of these particular towns is shown to involve the rationalisation of their integration core: integrated streets become better aligned and wider, and reach more directly into all parts of the town. However, the historic relationship between integration and block size is also based on mixture rather than a linear pattern of association. The final part uses these findings to advance a speculation about the origin of the syntax of these towns as compared to the syntax of the smaller settlements that Hillier and Hanson characterise as ‘beady rings’. This leads to a discussion of some of the abstract syntactic generators originally presented in The Social Logic of Space. In short, the final section of the paper argues that the lack of linear association between small blocks and integrated streets, in this particular sample, points to the emergence of gradually more complex generators of town form, generators which presuppose the ideas of the urban block and the street. These act upon the seeds of prior small aggregations, generated by simpler rules of adjacency

    Does cueing training improve physical activity in patients with Parkinson's disease?

    Get PDF
    Patients with Parkinson’s disease (PD) are encouraged to stay active to maintain their mobility. Ambulatory activity monitoring (AM) provides an objective way to determine type and amount of gait-related daily activities. Objective To investigate the effects of a home cueing training program on functional walking activity in PD. Methods In a single-blind, randomized crossover trial, PD patients allocated to early intervention received cueing training for 3 weeks, whereas the late intervention group received training in the following 3 weeks. Training was applied at home, using a prototype cueing device. AM was applied at baseline, 3, 6, and 12 weeks in the patient’s home, to record body movements. Postures and motions were classified as percentage of total time spent on (a) static activity, further specified as % sitting and % standing, and (b) % dynamic activity, further specified as % walking, % walking periods exceeding 5 seconds (W>5s) and 10 seconds (W>10s). Random coefficient analysis was applied. Results A total of 153 patients participated in this trial. Significant improvements were found for dynamic activity ( = 4.46; P 5s ( = 2.63; P 10s ( = 2.90; P < .01). All intervention effects declined significantly at 6 weeks follow-up. Conclusion Cueing training in PD patients’ own home significantly improves the amount of walking as recorded by AM. Treatment effects reduced after the intervention period, pointing to the need for permanent cueing devices and follow-up cueing training

    Descent groups among cognatic societies: the Dusun tribes of Inland Sabah/North Borneo

    Get PDF
    In the following discussion, the authors present a comparison of various societies in Borneo which includes for the first time a society that features descent groups. The claim that the Dusun society of the Upper Labuk River in inland North Borneo or Sabah possesses descent groups is one that has yet to be acknowledged in the wider Borneo literature. Descent groups are typically representative of some form of lineally ordered kinship system. Claims that unilineal or ambilineal kinship systems might exist in Borneo have been greeted with little interest, with caution or sometimes with outright rejection. By comparing the social groups produced by the Dusun society of the Upper Labuk River against the social groups produced by the more typical cognatic societies of Borneo, we are putting forward the claim that kinship systems are, at least in this region, a matter of great importance to the kind of social groups that are subsequently produced. The authors are not, however, claiming that lineally ordered kinship systems are in and of themselves able to produce structurally stable groups. Although the following discussion does necessarily refer to one model of tribal organisation derived from a lineally ordered society in Africa, it goes on to show that the lineally ordered Dusun tribes of Borneo were uniquely a product of local arrangements established for the purpose of accommodating a native customary law prohibiting marriages between close cousins

    The need for a definition of big data for nursing science: A case study of disaster preparedness

    Get PDF
    © 2016 by the author; licensee MDPI, Basel, Switzerland. The rapid development of technology has made enormous volumes of data available and achievable anytime and anywhere around the world. Data scientists call this change a data era and have introduced the term âBig Dataâ, which has drawn the attention of nursing scholars. Nevertheless, the concept of Big Data is quite fuzzy and there is no agreement on its definition among researchers of different disciplines. Without a clear consensus on this issue, nursing scholars who are relatively new to the concept may consider Big Data to be merely a dataset of a bigger size. Having a suitable definition for nurse researchers in their context of research and practice is essential for the advancement of nursing research. In view of the need for a better understanding on what Big Data is, the aim in this paper is to explore and discuss the concept. Furthermore, an example of a Big Data research study on disaster nursing preparedness involving six million patient records is used for discussion. The example demonstrates that a Big Data analysis can be conducted from many more perspectives than would be possible in traditional sampling, and is superior to traditional sampling. Experience gained from the process of using Big Data in this study will shed light on future opportunities for conducting evidence-based nursing research to achieve competence in disaster nursing.Link_to_subscribed_fulltex
