| 2 | Chinese nurses’ perceived impact of international educational experiences and cultural beliefs following a 1-year study abroad program: an exploratory study显示文摘Objectives:To examine the perceived impact of international educational experiences and cultural beliefs before and after completing a 1-year Masters of Science in Nursing program.Methods:An exploratory study was conducted among Chinese nurses studying abroad in a private medium-sized university in the United States.The 27-item electronic pre-survey was administered within 1 week of starting the program and the post-survey was administered 1 year later at the completion of the program.Results:Majority of participants(n=25)were female,23–36 years of age.Findings revealed that the perceived impact of international educational experiences assessed at the start of the program was similar to the perceived impact measured at the end of the 1-year program,suggesting that the students learned and experienced what they anticipated.There was a significant impact on cultural beliefs from the start of the program compared with the end of the program suggesting that a 1-year study abroad program does influence cultural beliefs.Conclusions:Understanding what is important to provide in a study abroad program and providing the educational experiences identified by students as impactful are avenues to help host universities best develop their programs.Findings suggested that the 1-year program can influence foreign students’cultural beliefs,yet the professional and personal impact of this change warrants further study. | Debra MWolf Hui-Xin Wub Kathleen Spadaro Diane FHunker | 2020 | Frontiers of Nursing2020，7，1： | 0 |
| 3 | Fitness-related selection on floral traits in the distylous plant Primula poissonii (Primulaceae)显示文摘Aims Reproductive fitness of different floral phenotypes varies within and/or among populations.These variations are important to understand the process of natural selection and the evolution of floral traits.In this study,we focused on a distylous,self-incompat-ible species,Primula poissonii,to investigate fitness-related selec-tion on floral traits.Our aim was to determine how traits vary as targets of natural selection and whether morph-specific selection occurs.Methods This study was conducted at two sites(Yushuizhai at 2700 m and Haligu at 3200 m)in the Lijiang Alpine Botanical Garden,northwest-ern Yunnan,southwestern China.Insects visiting flowers of P.pois-sonii were observed,captured and identified.Randomly selected plants of long-and short-styled morphs were labeled.Five floral/inflorescence traits were measured including floral display,corolla width(CW),floral tube length(FTL),tube opening width(TOW)and floral scape height.Fruit and seed set were recorded.The total num-ber of seeds per individual plant(plant fitness)and seed production per capsule(flower fitness)were calculated.Multiple regression analyses were used to quantify selection gradients.Important Findings The frequencies of the two morphs did not deviate from the expected 1:1 ratio at both sites.Except for FTL,the four other traits did not dif-fer significantly between the long-and short-styled morphs.Floral scape height,floral display and FTL differed between two sites.The selection regimes differed between two morphs and between two sites.At the Yushuizhai site,linear selection for shorter floral tubes was stronger in the short-styled morph.However,nonlinear selec-tion on the floral display was stronger in the long-styled morph than selection on the short-styled morph.At the Haligu site,linear selec-tion for a smaller corolla was stronger in the long-styled morph.A morph-specific nonlinear selection on CW and floral display was also detected.Morph-specific selections were detected through the estimation of flower fitness only in Haligu population.In this site,morph-specific linear selection was also detected for CW and floral display.Morph-specific nonlinear selection on traits was detected only in CW.We found that butterflies and sphingid moths dominated at Yushuizhai,while long-tongued bees dominated at Haligu.The difference in pollinator fauna suggested that selection on floral tubes may be due to differences in pollinator assemblages.Overall,variation of floral and/or inflorescence traits in P.poissonii was probably driven by pollinator selection.Selection regime dif-ferences between two morphs,in part,due the inter-morph diver-gences of sexual functions in distylous plant. | Hai-Dong Li Yan-Hui Zhao Zong-Xin Ren Zhi-Kun Wu Lorne MWolfe Peter Bernhardt Hong Wang | 2017 | Journal of Plant Ecology2017，10，3： | 0 |
