On the Construction of Deepening Anti - corruption Mechanism

It needs the foundation of system and the guarantee of organizational system for anti-corruption,but it is more necessary to build and form an effective anti-corruption mechanism,so that the anti-corruption can be really put into practice. Anti-corruption mechanism refers to a organic operation system of the interaction,interconnection and constraint between the constituent elements( parts) and elements of national anti-corruption,and as a system,anti-corruption mechanism should have the characteristics of system aticness,comprehensiveness,transparency,legalization,public participation,scientific dynam ic,and internationalism. The construction of deepening anti-corruption mechanism is the need for reconstructing the ruling legitimacy of the party and the governm ent. Adhering to the principle of treating both root causes and symptoms is necessary in the construction of anti-corruption m echanism,com bating and punishing corruption is an important part of anti-corruption,and the prevention and control of corruption is the basic project of anti-corruption. Therefore,the construction of prevention and control mechanism in the anti-corruption mechanism has a more far-reaching significance.

基于“五脏藏神”理论探析背俞穴治疗焦虑症的理论内涵

焦虑症是以持续的紧张、担忧或反复发作的惊恐为主要临床表现,《黄帝内经》关于“藏神”与“失神”的论述,发现五脏病变与情志失调共同作用引起焦虑,是焦虑症重要的病理基础。五脏神通过情志环路相互作用,形成对外界刺激的情绪和行为反应。“心神”被视为五脏神中的统帅,主导精神意识思维活动,而“脑神”则与记忆、视听觉等相关联,二者在调节人体精神活动中具有主次关系。本文基于“五脏藏神”理论探讨了背俞穴在治疗焦虑症中的应用和机制,认为刺激背俞穴调节五脏功能可能激活脊髓节段,产生神经体液调节影响自主神经系统,实现对焦虑症患者的身心共病特征的全面调节,达到抗焦虑样效应。

体育道德强度与体育专业大学生比赛中亲-反社会行为的关系:体育道德推脱的中介作用

体育道德强度反映了个体对体育情境中道德事件本身道德性质的认知水平,对于个体在运动中的体育道德行为具有重要影响。研究以568名体育专业大学生(男生307名,女生261名,平均年龄=19.1±1.04)为被试进行问卷调查,通过数理统计检验体育道德强度与体育专业大学生比赛中亲-反社会行为之间的关系和体育道德推脱在体育道德强度与比赛中亲-反社会行为关系中的中介作用。结果显示,体育道德强度与体育专业大学生比赛中的亲社会行为之间存在显著正相关,与比赛中的反社会行为之间存在显著负相关;体育道德推脱对体育道德强度和比赛中亲-反社会行为之间关系均表现出了显著的中介效应。研究表明,体育道德强度一方面直接影响体育专业大学生比赛中的亲-反社会行为,另一方面通过体育道德推脱的中介作用对比赛中的亲-反社会行为产生影响。

论人质情结在反劫持谈判中的应用

保证人质及其他人员的生命安全乃警方处置劫持人质案件的最高指导原则。自“慕尼黑事件”以来,反劫持人质谈判作为避免冲突升级的首选径路渐渐为人们所采纳。人质成为劫持者与警方对峙的“工具”后,有可能会对实施者产生强烈感情依恋(即人质情结),此种形成机理可从需求层级、防御机制以及认知失调理论视域予以探究。在反劫持谈判推进中,科学运用人质情结可有效保护人质安全,积极引导劫持者共商“非零和博弈”的和平方案。同时,警方也应注重危机落幕后的人质心理重建与完善,通过认知行为治疗的“七步疗法”来消弭劫持事件所造成的认知障碍和不良反应,增强其重启生活的信心与复原力,以助其逐步回归正常的生活轨道。

Critical Evaluation of a Survey Claiming “Long-Term Adverse Outcomes from Neonatal Circumcision”

We critically evaluate an online “Global survey of circumcision harm” that gauged beliefs of men who thought that their neonatal circumcision had harmed them. Sequential evaluation of the survey data and claims reveal numerous serious flaws that are at odds with strong scientific evidence. Moreover, the one-sided study design and “loaded” survey title meant the findings were not representative of the general population of circumcised males. None of the participants’ claimed physical problems were confirmed by a health practitioner. Belief in this seriously flawed survey has potential to cause psychological harm to vulnerable men influenced by anti-circumcision claims, and as such has serious detrimental implications for male sexual health. The survey appears driven less by empiricism and more by psychological forces, as we show in de-tail. The overwhelming body of high quality medical scientific evidence finds no adverse effect of male circumcision on sexual function and pleasure, but strong evidence for a wide array of lifetime benefits in protection against infections, dermatological problems, and genital cancers. Consistent with the United Nations Convention on the Rights of the Child, children are entitled to low risk procedures that are beneficial to their health. In conclusion, the survey and its uncritical presentation do a disservice to evidence-based medicine, sexual health, mental health, public health, human rights, and pediatric policy development. It should therefore be dismissed as unreliable.

<i>In Vivo</i>and <i>in Vitro</i>Evaluation of Anti Diabetic and Insulin Secretagogue Activities of <i>Capparis zeylanica</i>

Since ancient times, traditional medicines have been in the usage for the treatment of Diabetes mellitus. An edible fruit from traditional medicinal plant Capparis zeylanica (CZ) was studied for its anti diabetic, insulin secretagogue activities and mechanisms involved in it. In Streptozotocin induced diabetes rats, oral administration of Capparis zeylanica methanolic extract (CZME) (200 mg/kg body weight) for 28 days showed a significant reduction in blood glucose levels by 35.53% and enhanced circulating insulin levels by 81.82% than the diabetic control rats. The insulin secretagogue activity mechanisms of the extract were evaluated by using mouse insulinoma beta cell line (MIN6-β). The extract stimulated insulin release in dependent manner of glucose concentration (3 - 16.7 mM) and extract dose (5 - 500 μg/mL). The insulin releasing effect of the extract was significantly enhanced by 3-isobutyl-1-methyl xanthine, glibenclamide, elevated extracellular calcium and K+ depolarized media. This insulin release was significantly reduced in calcium blocking conditions (by nifedipine and EGTA), in the presence of potassium channel opener (diazoxide). Hence, anti diabetic activity of CZME might be a result of its stimulatory effect on insulin release from pancreatic beta cells via KATP channel dependent and independent ways. These results indicate that CZ fruits have the potential to use in diabetes therapy.

Exact Traveling Wave Solutions of Nano-Ionic Solitons and Nano-Ionic Current of MTs Using the exp(-φ (ξ ))-Expansion Method

In this work, the exp(-φ (ξ )) -expansion method is used for the first time to investigate the exact traveling wave solutions involving parameters of nonlinear evolution equations. When these parameters are taken to be special values, the solitary wave solutions are derived from the exact traveling wave solutions. The validity and reliability of the method are tested by its applications to Nano-ionic solitons wave’s propagation along microtubules in living cells and Nano-ionic currents of MTs which play an important role in biology.

Tye &Sardi’s Psychological, Psychosocial, and Psychosexual Aspects of Penile Circumcision*

Tye and Sardi recently reviewed the evidence purporting to implicate male circumcision, especially when performed early in infancy, in psychological problems in men. Here we provide a critical evaluation to determine the veracity of their evidence and claims. Missing from their review were critiques pointing out fundamental flaws in key studies. We argue that psychological stress in some men may be caused by anti-circumcision propaganda telling them that they are victims of “genital mutilation”, a term adopted from dissimilar female practices in particular ethnic groups. Sexual dissatisfaction results. We critically discuss claims about foreskin “gliding”, the eccentric foreskin-related sexual practice of “docking”, and the use of lubricant in masturbation. We further find that a study claiming to show numerous differences in socio-affective processing in men circumcised as neonates stem from statistically flawed and one-sided data that has been misinterpreted, and in fact shows the opposite of the hypothesis that psychological problems in some men can be attributed to the pain of their circumcision as newborns. Importantly, since the brain regions responsible for empathy, namely subcortical gray matter and white matter in frontal and parietal regions, were similar in neonatally circumcised and uncircumcised men, the null hypothesis remains null. In conclusion, we find no compelling evidence to support newborn circumcision pain being responsible for psychological problems in neonatally circumcised men. Men who come to believe that they are victims of their infant circumcision are in actual fact likely victims of false claims perpetrated by activist community groups with trenchant opposition to circumcision.
