Introduction Globalization not only increases human mobility, but changes the relationship between international migrants and their country of origin. With improved transportation systems and new technologies, migrants can stay connected to their homeland in multiple ways. In the past, it was costly and time-consuming for migrants to keep in touch with their homeland. Thus, the ability to assimilate into the culture and lifestyle of the mainstream society was important (Alba & Nee, 2003; Portes & Zhou, 1993). At the same time, migrants and minority groups also form ethnic enclaves (e.g., Chinatown, Little Italy) where they can maintain the culture and traditions of home and preserve a part of their cultural identity (Portes & Manning, 1986). Contemporary migrants, however, live in a transnational social field (Louie, 2006). They can easily communicate with their friends and family back home. Even if they reside in rural areas, most goods from the old country can be found in the new country. Migrants can shop online for the groceries, books, fashion, beauty products, kitchenware, etc. from their homeland. They can listen to hit songs in their native language, keep up with the major news events, follow the newest TV series, cheer for their favorite sports teams, watch live election results, and more—almost as if they have never left. Traveling back to the homeland is one important way for migrants to main transnational ties (Haller & Landolt, 2005). This type of travel is commonly known as diaspora tourism (Coles & Timothy, 2004), VFR tourism (Uriely, 2010), and roots tourism (Maruyama & Stronza, 2010). Migrants may visit the homeland for various reasons, including: leisure, business, local food, culture and heritage, quest, retain ties, finding oneself, roots-seeking, personal identity, connection with place, obligation to ancestors, recovery of social identity, and family togetherness (Kluin & Lehtom, 2012; Li & McKercher, 2016; Murdy, Alexander, & Bryce, 2018; Ray & McCain, 2012). Given that contemporary migrants can engage in transnational practices in the host society, and take part in various types of leisure activities that are related to the culture and lifestyle of home, the question is: do migrants still feel the need to visit the homeland in person? Or since everything is readily available, they do not need to go back as often as before. On one hand, participating in transnational leisure activities may strengthen their attachment to the homeland and increase their longing to return. On the other hand, the accessibility of homeland goods, services, culture, and relationships through global networks may decrease the desire and frequency of traveling back to the homeland. Therefore, the purpose of this study is to examine the relationship between transnational leisure activities and motivation to visit the homeland. Specifically, do migrants‘ transnational leisure participation and involvement influence their diaspora tourism motivation? Literature Review Transnationalism refers to the interconnected lifestyle and social experience of immigrants maintaining multiple ties with their home and host societies (Basch, Glick-Schiller, & Blanc, 1994). Transnationalism could be sustained through different types of activities, including economic, political, social, familial, religious, and cultural activities. Although leisure activities have not been a focus of transnationalism research, some cultural transnational practices overlap with leisure activities. The Immigration and Intergenerational Mobility in Metropolitan Los Angeles study (IIMMLA) found that 8.1% of second-generation immigrants participated in organizations associated with their parents‘ country of birth, and 48.7% watched TV or listened to the radio in their parents‘ language at least once a week or more (Rumbaut et al., 2008). The Immigrant Second Generation in New York study (ISGNY) revealed that ethnic music is very important to West Indian immigrants, and they listened to more ethnic music. Chinese-Americans, however, might listen to some Cantonese pop, but usually not traditional Chinese music (Kasinitz et al., 2008). Within leisure research, most studies on the leisure activities of immigrants employ the theory of acculturation. The focus was not on transnational leisure, but on immigrants‘ leisure participation within the mainstream culture of the host society. Many studies examined the effect of acculturation on immigrant leisure, be it participation, perceived benefits, motivations, or constraints. Floyd and Gramann (1993) compared Mexican- and Anglo-Americans to determine if the former‘s outdoor activity patterns and site visitation would be similar to the latter, based on different levels of structural assimilation. Shaull and Gramann (1998) also examined Hispanic- and Anglo-Americans to determine the impact of cultural assimilation on one‘s perceived benefits of outdoor recreation. They found a strong Anglo-conformity pattern in Hispanic-Americans‘ perception of nature-related benefits, while family-related benefits were less prone to the impact of cultural assimilation. Another study by Walker, Deng, and Dieser (2001) compared the motivations of Chinese-Canadians and Euro-North Americans for outdoor recreation. Their findings indicated that acculturation influenced the recreation motivation of Chinese-Canadians, both directly and indirectly through self-construal. The relationship between acculturation and leisure was also examined in Yu and Berryman‘s study (1996) on immigrant adolescents, which revealed a positive relationship between acculturation and recreational activities, and a negative relationship between acculturation and perceived barriers. A similar relationship was found in Scott, Lee, Lee and Kim‘s (2006) study of Korean migrants. They identified some constraints (i.e., lack of English proficiency and fear of discrimination) that varied by one‘s level of acculturation, while the biggest constraint, time, was not influenced by acculturation. Stodolska and Santos (2006) were the first to propose the concept of transnational leisure, and they defined it as leisure that is maintained by transnational migrants to foster their ties with their countries and communities of origin (p. 162). Huang, Norman, Ramshaw, and Haller (2015) identified different types of transnational leisure activities by second-generation Chinese-Americans, and categorized them into four types: ethnic events and festivals, ethnic social clubs and organizations, ethnic media and pop culture, and Internet-based activities. As these previous studies were qualitative in nature, there is a need for more quantitative research so as to compare and identify different patterns of transnational leisure (e.g., level of involvement, frequency of participation) and examine how transnational leisure relate to other variables. Methods This study aims to examine the transnational leisure involvement and travel motivation of diaspora tourists. Specifically, overseas Chinese residing in North America (i.e., the USA and Canada) was selected as the target population. The service of a reputable and reliable international online survey company was obtained to reach out to this specific population of interest. Data collection took place from December 2016 to January 2017. A total of 808 responses were gathered. A questionnaire was developed based on previous literature. A list of transnational leisure activities with 19 items was developed based on the work of Huang et al. (2015). The transnational leisure involvement scale was adapted from the works of Kyle, Graefe, Manning, and Bacon (2003) and Kyle, Bricker, Graefe, and Wickham (2004). The scale consists of 14 items and three dimensions: Attraction, Centrality, and Self-expression. As there are many types of transnational leisure activities, respondents were first asked to go through the list and indicate their frequency of participation in each activity. Next, they were asked to think about these activities as they answered the leisure involvement scale. The measures for diaspora tourism motivation was developed based on Poria and colleagues‘ scale for heritage tourism motivation (2004; 2006a; 2006b), Kluin and Lehto‘s (2012) scale for family reunion travel motivations, and Li and McKercher‘s (2016) qualitative study on diaspora tourists. The last section of the questionnaire will be used to collect demographic information. Findings EFA was conducted to explore if transnational leisure activities can be categorized into different types. Three items were removed due to double loading (i.e., Sing Chinese songs in the karaoke, Online shopping for Chinese/Asian items, and Connect with friends and relatives in China through social media). Factor 1 consisted of 3 items that are basic common activities in migrant life, and was labeled Basic transnational leisure (i.e., Eat Chinese food, Shop for Chinese/Asian groceries, and Celebrate Chinese holidays). Factor 2 consisted of 7 items that are related to pop culture and internet-based leisure activities, and was labeled Media-based transnational leisure (e.g., Listen to Chinese songs and music, Watch Chinese drama, Visit websites related to Chinese or Chinese-American culture, and Read/watch the news related to China). Contrary to the individualistic nature of the activities in Factor 2, Factor 3 consisted of 6 items that are more likely to be group activities, and related to social clubs events and activities (e.g., Attend events hosted by Chinese ethnic organizations, Participate in Chinese cultural activities, Play Chinese board or card games, Attend Chinese concerts/performances, and Follow Chinese/Chinese-American sports players or teams). Thus, Factor 3 was labeled Event-based transnational leisure. Respondents‘ participation in these activities was measured on a 5-point scale of frequency, from 1=Never to 5=Always/Everyday. Overall, Basic transnational leisure received the highest mean score (M=3.82), while the means for Media-based (M=2.86) and Event-based activities (M=2.62) were lower. Although the mean scores in Factor 2 and 3 were not high, it should be noted that the nature of these activities are different. Chinese migrants can Eat Chinese food every day, but they cannot Attending Chinese concerts every day. Therefore, the mean scores for Event-based activities were the lowest. Moreover, ANOVA was conducted to compare five migrant generation groups (e.g., first-generation migrants who were born in the old country and relocated to a new country and second-generation migrants are native-born in the new country). The second generation had the lowest level of participation, while the first generation and 4+ generation had the highest level of participation in most types of transnational leisure activities. Correlation analyses further revealed that the frequency of Media-based activities and Event-based activities were positively correlated to the number of homeland trips, while the relationship between Basic transnational leisure and number of homeland trips was not statistically significant. Lastly, CFA was conducted to confirm the underlying dimensions of Transnational Leisure Involvement: Attraction (6 items), Centrality (4 items), and Self-expression (4 items). EFA was conducted to identify the dimensions of diaspora tourism motivation. The 11 items loaded on one of two factors: Chinese Culture (6 items) and Family Heritage (5 items). Multiple regression analyses were conducted, with the three dimensions of transnational leisure involvement as independent variables, and the two dimensions of diaspora tourism motivation as dependent variables. It was found that Attraction and Centrality would influence respondents‘ motivation for Chinese Culture, while Attraction, Centrality, and Self-expression would influence respondents‘ motivation for Personal Heritage. Discussion Results showed that transnational leisure involvement is useful in understanding the activity patterns of different migrant generations. Specifically, the relationships between transnational involvement and diaspora tourism motivation were consistently positive, which provides an effective means of segmenting diaspora tourists. Transnational leisure activities are good opportunities for homeland destinations to connect with diaspora tourists prior to their travel. Other than direct promotional activities, transnational leisure provides an alternative way to increase diaspora tourists‘ level of engagement and frequency of travel to the homeland.

Comprehensive Assessment of Associations between ERCC2 Lys751Gln/Asp312Asn Polymorphisms and Risk of Non-Hodgkin Lymphoma

Zhou, Jue-Yu,He, Li-Wen,Liu, Jie,Yu, Hai-Lang,Wei, Min,Ma, Wen-Li,Shi, Rong Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.21

Background: Excision repair crossing-complementing group 2 (ERCC2), also called xeroderma pigmentosum complementary group D (XPD), plays a crucial role in the nucleotide excision repair (NER) pathway. Previous epidemiological studies have reported associations between ERCC2 polymorphisms and non-Hodgkin lymphoma (NHL) risk, but the results have remained controversial. Materials and Methods: We conducted this meta-analysis based on eligible case-control studies to investigate the role of two ERCC2 polymorphisms (Lys751Gln and Asp312Asn) in determining susceptibility to NHL. Ten case-control studies from several electronic databases were included in our study up to August 14, 2014. Pooled odds ratios (ORs) and 95% confidence intervals (CIs) were calculated using fixed- or random-effects models to estimate the association strength. Results: The combined results based on all studies did not show any association between Lys751Gln/Asp312Asn polymorphisms and NHL risk for all genetic models. Stratified analyses by histological subtype and ethnicity did not indicate any significant association between Lys751Gln polymorphism and NHL risk. However, a significant reduced risk of NHL was found among population-based studies (Lys/Gln versus Lys/Lys: OR=0.87, 95% CI=0.77-0.99, P=0.037) but not hospital-based studies. As for Asp312Asn polymorphism, there was no evidence for the association between this polymorphism and the risk of NHL in all subgroup analyses. Conclusions: This meta-analysis suggests that there may be no association between Lys751Gln/Asp312Asn polymorphism and the risk of NHL and its two subtypes, whereas ERCC2 Lys751Gln heterozygote genotype may provide protective effects against the risk of NHL in population-based studies. Therefore, large-scale and well-designed studies are needed to clarify the effects of haplotypes, gene-gene, and gene-environment interactions on these polymorphisms and the risk of NHL and its different histological subtypes in an ethnicity specific population.

Suppression of Radiative Damping and Enhancement of Second Harmonic Generation in Bull’s Eye Nanoresonators

Yi, Jue-Min,Smirnov, Vladimir,Piao, Xianji,Hong, Jiho,Kollmann, Heiko,Silies, Martin,Wang, Wei,Groß, Petra,Vogelgesang, Ralf,Park, Namkyoo,Lienau, Christoph American Chemical Society 2016 ACS NANO Vol.10 No.1

<P>We report a drastic increase of the damping time of plasmonic eigenmodes in resonant bull's eye (BE) nanoresonators to more than 35 fs. This is achieved by tailoring the groove depth of the resonator and by coupling the confined plasmonic field in the aperture to an extended resonator mode such that spatial coherence is preserved over distances of more than 10 mu m. Experimentally, this is demonstrated by probing the plasmon dynamics at the field level using broadband spectral interferometry. The nanoresonator allows us to efficiently concentrate the incident field inside the central aperture of the BE and to tailor its local optical nonlinearity by varying the aperture geometry. By replacing the central circular hole with an annular ring structure, we obtain 50-times higher second harmonic generation efficiency, allowing us to demonstrate the efficient concentration of long-lived plasmonic modes inside nanoapertures by interferometric frequency-resolved autocorrelation. Such a light concentration in a nanoresonator with high quality factor has high potential for sensing and coherent control of light-matter interactions on the nanoscale.</P>

Comparison of the Efficacy and Safety of EFGR Tyrosine Kinase Inhibitor Monotherapy with Standard Second-line Chemotherapy in Previously Treated Advanced Non-small-cell Lung Cancer: a Systematic Review and Meta-analysis

Qi, Wei-Xiang,Shen, Zan,Lin, Feng,Sun, Yuan-Jue,Min, Da-Liu,Tang, Li-Na,He, Ai-Na,Yao, Yang Asian Pacific Journal of Cancer Prevention 2012 Asian Pacific journal of cancer prevention Vol.13 No.10

Purpose: To compare the efficacy and safety of epidermal growth factor receptor tyrosine kinase inhibitormonotherapy (EFGR-TKIs: gefitinib or erlotinib) with standard second-line chemotherapy (single agent docetaxel or pemetrexed) in previously treated advanced non-small-cell lung cancer (NSCLC). Methods: We systematically searched for randomized clinical trials that compared EGFR-TKI monotherapy with standard second-line chemotherapy in previously treated advanced NSCLC. The end points were overall survival (OS), progression-free survival (PFS), overall response rate (ORR), 1-year survival rate (1-year SR) and grade 3 or 4 toxicities. The pooled hazard ratio (HR) or risk ratio (RR), with their corresponding 95% confidence intervals (CI) were calculated employing fixed- or random-effects models depending on the heterogeneity of the included trials. Results: Eight randomized controlled trials (totally 3218 patients) were eligible. Our meta-analysis results showed that EGFR-TKIs were comparable to standard second-line chemotherapy for advanced NSCLC in terms of overall survival (HR 1.00, 95%CI 0.92-1.10; p=0.943), progression-free survival (HR 0.90, 95%CI 0.75-1.08, P=0.258) and 1-year-survival rate (RR 0.97, 95%CI 0.87-1.08, P=0.619), and the overall response rate was higher in patients who receiving EGFR-TKIs(RR 1.50, 95%CI 1.22-1.83, P=0.000). Sub-group analysis demonstrated that EGFR-TKI monotherapy significantly improved PFS (HR 0.73, 95%CI: 0.55-0.97, p=0.03) and ORR (RR 1.96, 95%CI: 1.46-2.63, p=0.000) in East Asian patients, but it did not translate into increase in OS and 1-year SR. Furthermore, there were fewer incidences of grade 3 or 4 neutropenia, febrile neutropenia and neutrotoxicity in EGFR-TKI monotherapy group, excluding grade 3 or 4 rash. Conclusion: Both interventions had comparable efficacy as second-line treatments for patients with advanced NSCLC, and EGFR-TKI monotherapy was associated with less toxicity and better tolerability. Moreover, our data also demonstrated that EGFR-TKImonotherapy tended to be more effective in East Asian patients in terms of PFS and ORR compared with standard second-line chemotherapy. These results should help inform decisions about patient management and design of future trials.

Yanping Chen,Wei Shi,Jue Wang,Huifen Yan,Chao Guo 보안공학연구지원센터 2016 International Journal of Grid and Distributed Comp Vol.9 No.4

In the service composition life cycle, the target between service requester and service provider is quite different, which will cause the Web service SLA negotiation problem. The implementation of Web service relies on the interaction between the service provider and the service requester. In this article, the game model of Web Service negotiation process is proposed and solutions of the multi-participant and dynamic game model are gave. Then, we obtained the effective method of SLA generation. Experiments show that our method will ensure the common interests both service requesters and service providers.

Prognostic Value of Tissue Vascular Endothelial Growth Factor Expression in Bladder Cancer: a Meta-analysis

Huang, Yu-Jing,Qi, Wei-Xiang,He, Ai-Na,Sun, Yuan-Jue,Shen, Zan,Yao, Yang Asian Pacific Journal of Cancer Prevention 2013 Asian Pacific journal of cancer prevention Vol.14 No.2

Objective: The prognostic role of vascular endothelial growth factor (VEGF) in bladder cancer remains controversial. This meta-analysis aimed to explore any association between overexpression and survival outcomes. Methods: We systematically searched for studies investigating the relationships between VEGF expression and outcome of bladder cancer patients. Study quality was assessed using the Newcastle-Ottawa Scale. After careful review, survival data were extracted from eligible studies. A meta-analysis was performed to generate combined hazard ratios (HRs) for overall survival (OS), disease-free survival (DFS) and disease-specific survival (DSS). Results: A total of 1,285 patients from 11 studies were included in the analysis. Our results showed that tissue VEGF overexpression in patients with bladder cancer was associated with poor prognosis in terms of OS (HR, 1.843; 95% CI, 1.231-2.759; P = 0.003), DFS (HR, 1.498; 95% CI, 1.255-1.787; P = 0.000) and DSS (HR, 1.562; 95% CI, 0.996-1.00; P = 0.052), though the difference for DSS was not statistically significant. In addition, there was no evidence of publication bias as suggested by Begg's and Egger's tests except for DFS (Begg's test, P = 0.221; Egger's test, P = 0.018). Conclusion: The present meta-analysis indicated elevated VEGF expression to be associated with a poor prognosis in patients with bladder cancer.

Generalized Beamforming Design for Cooperative MIMO Multirelay Networks with Infinite Constraints and Imperfect CSI

Yu, Haiyang,Duan, Wei,Sun, Qiang,Wang, Xia,Wang, Jue,Li, Jun,Choi, Jaeho Hindawi Limited 2018 Mathematical problems in engineering Vol.2018 No.-

<P>A generalized base station-relay-user equipment (BS-Relay-UE) beamforming design is investigated for a cooperative multiple-input multiple-output (MIMO) multirelay networks with imperfect channel state information (CSI). In order to minimize the worst-case mean square error (MSE) which is subject to a semi-infinite (SI) relay power constraints, a generalized optimal beamforming structure for the relay amplifying matrix is effectively proposed, and then the SI relay power constraints are converted into linear matrix inequalities (LMIs) version. In such conversion, the objective problem recasts as a decoupled biconvex semidefinite programming (SDP) one which can be efficiently solved by the proposed alternating algorithm. The system performance has been verified in terms of worst-case MSE using a set of qualitative analyses. The results show us that the proposed beamforming method outperforms the conventional schemes and can also effectively reduce the computational complexity when it is compared to the cutting-set schemes and also to the nonrobust ones.</P>

ZNRF1 can inhibit proliferation and stemness properties of leukemia NB4 cells

Yuechao Zhao,TongJuan Li,Lei Zhao,Jue Wang,Zhen Shang,Wei Huang,Jianfeng Zhou 한국통합생물학회 2016 Animal cells and systems Vol.20 No.4

As a newly discovered E3 ubiquitin ligase, ZNRF1 protein participates in controlling Wallerian degeneration, but the role in cancer biology has been seldom reported. We analyzed the change of proliferation, apoptosis, stemness and protein levels of AKT and STAT5 after leukemia NB4 cells were treated with ZNRF1 siRNA and with expression vector. The results showed that overexpression of ZNRF1 inhibited proliferation and increased apoptosis of NB4 cells, but ZNRF1 siRNA did not influence the proliferation and apoptosis. Over-expression of ZNRF1 diminished cancer stem cell properties and down-regulated AKT and STAT5. This is the first study to show that ZNRF1 inhibited proliferation and stemness properties of leukemia NB4 cells possibly through AKT signal and STAT5 signal.
