What drives successful social networking services? A comparative analysis of user acceptance of Facebook and Twitter

This study identifies perceived mobility, security, connectedness, system and service quality, usefulness, attitude, and flow experience as key motivational factors for using social networking services (SNSs), and develops a theoretical model that explicates the process in which users adopt Facebook and Twitter by integrating these factors with the technology acceptance model (TAM). While results of structural equation modeling (SEM) on the collected data (N = 2,214) verified the validity and reliability of the research model, Facebook and Twitter users were found to emphasize different motivational factors when deciding to use SNSs. The implications of notable findings and directions for future studies are discussed.     

Do Children With Gender Dysphoria Have Intense/Obsessional Interests?

This study examined whether children clinically referred for gender dysphoria (GD) show increased symptoms of autism spectrum disorder (ASD). Circumscribed preoccupations or intense interests were considered as overlapping symptoms expressed in GD and ASD. In gender-referred children (n = 534; 82.2% male) and their siblings (n = 419; 57.5% male), we examined Items 9 and 66 on the Child Behavior Checklist, which measure obsessions and compulsions, respectively. Non-GD clinic-referred (n = 1,201; 48.5% male) and nonreferred (n = 1,201; 48.5% male) children were also examined. Gender-referred children were elevated compared to all other groups for Item 9, and compared to siblings and nonreferred children for Item 66. A gender-related theme was significantly more common for gender-referred boys than male siblings on Item 9 only. A gender-related theme was not significantly more common for gender-referred girls compared to their female siblings on either item. The findings for Item 9 support the idea that children with GD show an elevation in obsessional interests. For gender-referred boys in particular, gender-related themes constituted more than half of the examples provided by their mothers. Intense/obsessional interests in children with GD may be one of the factors underlying the purported link between GD and ASD.

Surviving grief: An analysis of the exchange of hope in online grief communities

Online grief communities represent relatively new forms of peer support. However, the degree to which they are helpful for individual grieving processes is unknown. To date, no research has evaluated the type or quality of support exchanged in online grief communities. To begin to address these questions, this study analyzed 564 messages from internet grief websites to: (1) classify the type of helping skills used, and (2) extract themes contained in the content of the messages. Messages selected for analysis were the first response to an original post, assuming they would be the first effort to provide support to a grieving individual. Results revealed a majority of responses contained self-disclosure. Themes in the messages suggested provision of more than "one-way" support; messages themes also included exchanging hope for the future by sharing one's own story, validating the grief experience, providing resources, and exchanging psychosocial support. Clinical implications and research recommendations are discussed.     

红外吸收峰的位置波动:归因于单一谱带的频移还是重叠谱带相对强度的变化?

红外吸收峰的位置波动可能由单一谱带的实际频移或是邻近重叠谱带相对强度的变化而产生。本文通过主成分分析法(PCA)有力地证明了光谱位置波动的根源往往归因于后一种机理。PCA能灵敏有效地区分单一谱带的实际频移与由重叠谱带相对强度变化所产生的最大峰移。对于由分子相互作用强度变化所诱导,并在振动光谱领域较为常见的所谓带移的概念,往往由于其隐含了谱带的固有频移而有些概念误导。在许多红外光谱中,峰极大值表面的位移,一般产生于两条重叠谱带相对贡献的变化,而不是分子相互作用强度变化所诱导的单一谱带的缓慢频移。这个观点可以帮助我们解释振动光谱所探测到的分子相互作用。     

Advocacy Coalitions and Health Politics in Korea

This article analyses the political dynamics underlying health care reform in Korea after the Asian economic crisis. The reform was a significant volte‐face in respect of the social policy paradigm, which now aims to enhance equity in National Health Insurance. The article pays special attention to the evolution of the advocacy coalition for equity in health policy and how it developed the two attributes required for successful policy change: institutional strength and the elaboration of policy rationale for reform. This process was not a simple linear development but a combination of setbacks and advances. The article also takes into consideration the structural conditions that set the policy environment over the course of the advocacy coalition's evolution since the 1960s. In short, the policy reform of 2000 was not a simple policy change in response to the economic crisis, but rather the outcome of the long‐term evolution of the advocacy coalition for equity in health policy.     

In search of the “best” growth inhibitor

In searching for the “best” growth inhibitor, we decided to consider growth inhibition in terms of the lengths of the terminal sprouts. For it is logical to infer that the trees with the longer sprouts (after a 20-month period) will most likely be the ones that will need trimming in the future. Additionally, we reasoned that if a particular treatment produced a smaller proportion of “long” sprouts, then it would be a more effective growth inhibitor. It was now necessary to define what was meant by “long”. After consultation with foresters we chose cutoff lengths of 15.0, 25.0 and 35.0 cm. Hence the response variable was chosen to be the proportion of the terminal sprouts on a tree that exceeded a specified cutoff length. By varying the cutoff lengths, we would minimize the effect of the arbitrariness involved in choosing one particular length.     

Socioeconomic indexes and the new 1980 census occupational classification scheme

Because of their usefulness in a wide variety of research, socioeconomic scores have been revised several times to incorporate changes in the relevant components of the occupational structure and to conform with the changing census occupational classification schemes. The major purpose of this paper is to provide socioeconomic scores for the 1980 census occupational classification scheme. First, however, we review earlier versions of the socioeconomic index (SEI), summarize the relevant disparities between the 1970 and 1980 census occupational classificatory schemes, and then explain in detail the procedures used to reconcile the SEI with 1980 occupational codes. We also show that, although the 1980 occupational classificatory scheme differs radically from the 1970 occupational scheme, the socioconomic scores for 1980 occupational data replicate features found in 1970 data.
