The theory-based intervention of individualized music has been evaluated clinically and empirically leading to advancement and refinement of an evidence-based protocol, currently in its 5th edition. An expanded version of the protocol was written for professional health care providers with a consumer version tailored for family caregivers. The underlying mid-range theory is presented along with a seminal study that was followed by further research in the United States, Canada, Great Britain, France, Sweden, Norway, Japan and Taiwan. Key studies are summarized. Given its efficacy when implemented by research staff, studies have advanced to testing the intervention under real-life conditions when implemented and evaluated by trained nursing assistants in long-term care facilities and visiting family members. In addition, one study evaluated the implementation of music by family members in the home setting. Initial research focused on agitation as the dependent variable with subsequent research indicating a more holistic response such as positive affect, expressed satisfaction, and meaningful interaction with others. The article advances by describing on-line programs designed to train health care professionals in the assessment, implementation and evaluation of individualized music. In addition, Gerdner has written a story for apicture book intended for children and their families(in press). The story models principles of individualized music to elicit positive memories, reduce anxiety and agitation, and promote communication. The article concludes with implications for future research. 展开更多

In this study, marine microplankton were identified by combining standard light microscopy with Sanger 18S rRNA gene sequencing. The image-matching individual PCR technique was applied to identify the image collectable unicellular microplankton to genera. Instead of pure strain culture and morphological identification, microplankton individual cells were isolated and fixed with glutaraldehyde, frozen and stored for months. Finally, they were imaged under a microscope and molecularly identified via phylogenetic analysis of their 18S ribosomal RNA gene(18S rDNA). Microplankton cells were collected at 30 locations in South China Sea, and were assigned to 21 known and 4 unidentified genera(2 uncultured fungi and 2 uncultured stramenopiles) with phylogenetic analysis in parallel to the morphological identification. 展开更多

Malaysia has long been involved in the initiative of becoming a high income country by the year 2020. In this essence, fighting and eliminating any means of corruption in the public and private companies have been one of the key challenges in the long run. The globalization of businesses has somehow led to an increase in the number of unethical conduct and hazardous corruption. In the urge to enliven ethics and integrity in a company and among employees, the whole business processes and stakeholders should position code of ethics and integrity at its highest standard. However, can ethics and integrity really increase the company's reputation, strengthening its business operations and sustainability, and deliver trust amongst employees and employers? The objective of this study is to analyze the perceptions of employees on issues pertaining ethics and integrity. The study has been conducted in one of the giant telecommunication companies in Malaysia where a sample of 7,056 employees were the participants involved in the survey. The study has used questionnaires to collect data. The data have then been analysed using the SPSS data analysis software. The findings explained that employees view the company as an ethical place to work where the finance department is deemed to have the highest level of integrity. While in matters of corruption risk areas, there are still practices of bribery. It is also founded that a majority of respondents about 93% agree that the company's initiatives are effective in building business integrity and that the level of business ethics and integrity has improved over the last two years. Running a business with ethics and integrity while selecting the fight business partners will create a corporation of ethics, integrity, and anti-corruption. 展开更多

Individuals often get lost behind the diagnosis of Alzheimer’s disease (AD) while widespread differences between these patients are morecommon than similarities. Socioemotional Selectivity Theory (SST) suggests that as we age our goals change from future-oriented (acquiringnew information) to present-oriented (enhancing the emotional, especially positive, meaning of encounters). The goal of the current article is to examine whether the principles of SST might also apply for people with AD. Some aspects of SST are found especially in the early stages of AD when awareness is often intact and cognitive impairment is relatively limited. This review has clinical significance for the treatment of AD because it focuses on what is important to the individual rather than treating patients as a homogenous group. It also highlights the importance of social networks and emphasizes the role of the proxy in AD care. Lastly, it suggests that if those with AD (like the healthy elderly) have a positivity bias then positive emotional stimuli/wording/instructions could usefully be employed in their daily treatment. I suggest that SST may be a useful starting point when attempting to address what matters to individuals with AD and conclude by providing a few suggestions for future studies. 展开更多

With stepwise development of Chinese enterprise,management problem is increasingly prominent,especially human resource management issues. Facing international environment of entering into World Trade Organization,the country accelerates construction pace of human resource management subject in colleges and universities,which provides professional channel for management efficiency and market competition ability of Chinese enterprise,but it is still far from practice. In this paper,the concept,origin and inhibition factors of ingroup preference are elaborated. Based on the visual angle of ingroup preference,started from four dimensions( enterprise incentive system,talent management idea,psychological contract and employee communication consciousness),main problems existing in employee relationship management of modern enterprise are explored. It is specially emphasized that manager often holds the blame in front of dealing with the crisis after contradiction,which is " fatal point" neglected in employee relationship management of modern enterprise. To improve its core competitive power,enterprise must value harmonious relationship with employees. 展开更多

Recently, a great tide of English teaching reform swept across China, advocating the innovation of educational concept and teaching mode. However, the phenomenon of rigid uniformity in teaching process is still commonly seen, neglecting the individual discrepancy of students. The individual discrepancy is manifested by both the congenital heredity and the acquired disposition. Supported by the Chinese traditional theory of teaching students in accordance with their aptitude and Vygotsky's "the zone of proximal development" theory, this paper illustrates the importance of paying attention to the individual discrepancy from the perspective of students' growing background and personality. In addition, standing on the point of view of relevant authority and English teacher, the author tries to put forward some countermeasures. 展开更多

As one of the most significant critical essays of T.S.Eliot,Tradition and Individual Talent has defined writing as a process during which the primitive oneness has seized the individual writer of figurative descriptions to help represent itself.This theory has latter been practiced in Eliot’s Wasteland,and shows its similarity with The Birth of Tragedy,written by Friedrick Nietzsche,the German philosopher.Eliot’s‘tradition’has been concluded by Nietzsche as‘Dionysian Spirit’,which represents oneness transcending good and evil,past and present,while‘individual talent’has resembled‘Apollonian Spirit’in the urge for original figuration as an apparatus.The paper aims to explain and compare the definitions of‘tradition’and‘individual talent’of Eliot’s work with that of‘Dionysian spirit’and‘Apollonian Spirit’in Nietzsche’s illustrations,so as to provide a deeper understanding of these two works by unveiling the individual and social sameness and difference of Eliot and Nietzsche. 展开更多
