‘Fractured communities’: uncertainty,stress, and (a lack of) communal coping in Palestinian refugee camps

This study examined how communal coping reveals itself in Palestinian refugee camps and the conditions that promote or prevent its occurrence. Individual and dyadic interviews were conducted with 40 mothers and one of their adolescent children living in Palestinian refugee camps in Lebanon. The results revealed that communal coping existed within the mother–adolescent dyad to a certain extent, but was rare within the larger context of the refugee camps. While families and neighbors did not typically verbalize their hardships and actively cope with them as a group, there was often an implicit recognition that they were all experiencing the same uncertainty and stress. Acting upon their uncertainty as a collective, however, was greatly hampered by mistrust within and outside the camps, due to widespread violence, privacy violations, vying for scarce resources, and disloyalty. Parents and adolescents also engaged in protective buffering whereby they attempted to reduce the stress of the family by keeping stress and fears to themselves rather than communicating about them. Even though protective buffering helped the refugees cope with chronic uncertainty and maintain a sense of normalcy, it prevented them from acting upon the problem as a group. Finally, parents emphasized that the child’s education provided hope for the future. Practical implications are discussed.  相似文献

First-rib stress fracture in two adolescent swimmers: a case report     

Sara Low  Michael Kern 《Journal of sports sciences》2016,34(13):1266-1270

First-rib stress fractures have been described in adolescent athletes in various sports, with only one prior case report of first-rib stress fractures in an adolescent female swimmer. There is a need for research on the cause, management, and prevention of these injuries as they lead to significant morbidity and critical time away from sport for these aspiring athletes. We aimed to describe first-rib stress fractures as a potential cause for non-specific atraumatic chronic shoulder pain in adolescent swimmers and to discuss the different presentations, unique risk factors, treatment, and potential injury prevention strategies of such fractures. We discussed two such cases which were successfully treated with activity modification with restriction of all overhead activity, gradually progressive physical therapy and a return to swimming protocol. First-rib stress fractures can vary in presentation and should be in the differential diagnosis in adolescent swimmers with chronic shoulder pain. These injuries can be successfully managed with rest from overhead activities and physical therapy. Gradual return to competitive swimming can be achieved even with non-union of a first-rib stress fracture. Emphasis on balanced strength training in different muscle groups and proper swimming technique is essential to prevent these injuries.  相似文献   

低温胁迫下镧对水稻种子萌发的影响   总被引：3，自引：0，他引：3  

刘惠娜  钟东方  许良政 《嘉应学院学报》2007,25(3):72-76

以水稻(Oryza sativa)种子为实验材料,研究了不同浓度稀土元素镧浸种对水稻种子低温萌发的影响。结果表明:15℃低温胁迫抑制水稻种子的萌发,浸种期用硝酸镧处理能够提高种子的抗逆性。低浓度((50~250)×10-6mol/L)硝酸镧浸种能提高水稻种子发芽率、发芽势、呼吸速率和过氧化氢酶活性,提高种子抗寒能力,实验发现用硝酸镧处理种子萌发以250×10-6mol/L浓度为最佳,低温胁迫下,发芽率提高9.67%,呼吸速率提高56.25%,过氧化氢酶活性提高1.73%。350×10-6mol/L以上高浓度对水稻种子的萌发无明显影响。  相似文献   

Effect of repeat-sprint training in hypoxia on post-exercise interleukin-6 and F2-isoprostanes     

Paul S. R. Goods  Brian Dawson  Grant J. Landers  Christopher J. Gore  Kevin Croft  Peter Peeling 《European Journal of Sport Science》2016,16(8):1047-1054

This investigation examined the oxidative stress (F₂-Isoprostane; F₂-IsoP) and inflammatory (interleukin-6; IL-6) responses to repeat-sprint training in hypoxia (RSH). Ten trained male team sport athletes performed 3(sets)*9(repetitions)*5?s cycling sprints in simulated altitude (3000?m) and sea-level conditions. Mean and peak sprint power output (MPO and PPO) were recorded, and blood samples were collected pre-exercise, and again at 8 and 60?min post-exercise. Both MPO and PPO were significantly reduced in hypoxia (compared to sea-level) in the second (MPO: 855?±?89 vs. 739?±?95?W, p?=?.006; PPO: 1024?±?114 vs. 895?±?112?W, p?=?.010) and third (MPO: 819?±?105 vs. 686?±?83?W, p?=?.008; PPO: 985?±?125 vs. 834?±?99?W, p?=?.008) sets, respectively. IL-6 was significantly increased from pre- to 1?h post-exercise in both hypoxia (0.7?±?0.2 vs. 2.4?±?1.4?pg/mL, p?=?.004) and sea-level conditions (0.7?±?0.2 vs. 1.6?±?0.3?pg/mL, p?d?=?0.80) suggesting higher IL-6 levels of post-hypoxia. F₂-IsoP was significantly lower 1?h post-exercise in both the hypoxic (p?=?.005) and sea-level (p?=?.002) conditions, with no differences between trials. While hypoxia can impact on exercise intensity and may result in greater post-exercise inflammation, it appears to have little effect on oxidative stress. These results indicate that team sport organisations with ready access to hypoxic training facilities could confidently administer RSH without significantly increasing the post-exercise inflammatory or oxidative stress response.  相似文献

Social Work Intervention with White Collared Employees and Their Families     

Y.?S.?SiddeGowdaEmail author 《International journal for the advancement of counseling》2004,26(4):421-432

This investigation presents a framework for understanding and also to test the efficacy of Social Work intervention on the well being of the white collared employee (industrial employee) and his/her family. A comprehensive and intensive personal- family exploration was done to uncover the relatedness of seemingly disparate areas of the clients lives. A total of 80 executives (industrial employees) served as subjects. A baseline assessment was done using structured, standardized interview-schedules/questionnaires. The results of the study can be enumerated as follows: After the Social Work intervention, the executives in occupational profile, there were significant changes in Role perception, overload, role conflict, low status and poor peer relations. In coping strategies there was significant improvement in sub-scales like problem solving and unproductive coping. Significant reduction was noticed in their proneness to heart disease, depression, inadequate mental mastery, and perceived ill health. There was significant improvement in their family group support, and in their expressiveness, achievement, orientation, active-recreational and organizational characteristics.  相似文献   

弧形混凝土结构温度应力计算研究     

黎永索  卫军 《湖南城市学院学报》2003,24(6):10-13

对弧形混凝土结构温度应力的计算研究表明，弧形结构的环向应力沿高度方向基本一致，可以简化为拱单元计算，拱单元的支座约束可以用“等效暗柱”来计算；结构两侧温差对弧形结构的环向应力的影响较轴线温差变化的影响更大，控制温度裂缝主要是控制结构物两侧的温差．通过设置滑动层，减小结构的抗侧移刚度。则弧形混凝土结构可以作无缝设计．  相似文献
