Abstract In many animal species, males direct more intense courtship towards females they have not previously encountered, than towards females with which they have previously mated. To test the factors responsible for this ＂Coolidge Effect＂, we need studies on a wide range of taxa - including those with mating systems in which we would not expect （based on current theory） that such an effect would be evident. The Coolidge Effect has been documented in several lizard species, but has not been looked for （and would not be expected） in snakes. We conducted experimental trials with red-sided garter snakes Thamnophis sirtalis parietalis at a communal den in Manitoba, to see whether previous exposure to a female （either courting, or courting plus mating） modified male mate choice or courtship intensity. In keeping with prediction from theory （but contrary to an early anecdotal report）, male garter snakes did not modify their courtship behaviour based upon their familiarity （or lack thereof） with a specific female. At least in large courting aggregations, male snakes may maximize their fitness by basing mate-choice upon immediate attributes of the female （body size, condition, mated status） and the intensity of competition （numbers and sizes of rival males） rather than information derived from previous sexual encounters .

AIM： To investigate the effect of chronic inflammatory bowel disease （CIBD） specific risk factors for cholecystolithiasis, as duration and involvement pattern of the disease and prior surgery in patients with Crohn＇s disease （CD） and ulcerative colitis （UC）. METHODs： A total of 222 patients with CD （135 females, 87 males, average age, 35.8±11.8 years; range 17-81 years） and 88 patients with UC （39 females, 49 males; average age, 37.2±13.6 years; range 16-81 years） underwent clinical and ultrasound examinations. Besides age, sex and degree of obesity, patients＇ CIBD specific parameters, including duration and extent of disease and prior operations were documented and evaluated statistically using logistic regression. REsLTLTs： The overall prevalence of gallbladder stone disease in patients with CD was 13% （n = 30）. Only age could be shown to be an independent risk factor （P = 0.014）. Compared to a collective representative for the general population in the same geographic region, the prevalence of cholecystolithiasis was higher in all corresponding age groups. Patients with UC showed an overall prevalence of gallbladder stone disease of only 4.6%. CONCLUsION：Only age but not disease-specific factors such as duration and extent of disease, and prior surgery are independent risk factors for the development of cholecystolithiasis in patients with CIBD.

目的呼吸防护在医疗卫生工作中至关重要,应使用适当的颗粒过滤呼吸器和等效的呼吸防护用品,以确保良好的佩戴气密性,最大限度地降低医务人员的空气传播感染风险。该文旨在对呼吸防护用品适合性检验和密合性检查有效性研究进行综述和分析。方法系统检索了2003年1月至2022年4月发表的文献,检索范围包括CINAHL、Cochrane图书馆、EMBAsE、PubMed、Ovid数据库Medline子库和灰色文献。研究方案已在PROsPERO注册(CRD42020213968)。结果共检索出561篇文献,25篇被纳入该综述,包括22项量性研究和3篇指南文献。在评估呼吸防护用品的有效性方面,适合性检验是更有效且被广泛采用的可靠方法,但呼吸防护程序应该同时包括适合性检验和密合性检查,以最大限度地提高呼吸防护用品的有效性。新型冠状病毒疫情凸显了医务人员相关知识的缺乏,相关教育培训可有效提高呼吸防护用品使用的有效性。结论为确保医务工作者的安全,适合性测试和密合性检查均应采用。建议由专业人员实施全面的呼吸防护项目,包括教育培训、适合性测试和密合性检查,还需要探索适用于实际使用环境的适合性检验方法。

Chinese Business Review 2011年第12期10卷 1111-1130页

作者： Rodolfo Ballestrazzi Michela C. mason Federico Nassivera University of Udine Udine Italy

The purpose of this paper falls within the theoretical framework of green marketing. It investigates the relationships that exist between the motives relating to aquacultural products marketed under the private label of a traditional retailer （Coop）, the attitude towards their purchase, the perception of their quality, their reliability and the willingness to pay for them. Particular importance is given to the green motives, those that lead to a preference for a product made with specific renewable energies such as biogas. The structural equation models （sEM） technique is used to develop propositions representing a theoretical approach to the integration of green marketing, in the context of the process for purchasing Coop brand fish. With regard to distinguishing between the motives, we referred to the approach that sets out three different types of motive： clean, green and ethical. The resulting managerial implications make it possible to assess how much the different types of motive influence the choices of the consumers. Managers will benefit from the results of this paper by understanding better the benefits for consumers of aquacultural products from renewable energy such as biogas. The originality of the paper lies in its focusing on green purchase behaviour in a poorly investigated sector such as that of fish breeding. The paper contributes to an understanding of the factors that influence environmentally responsible purchase behaviour and their exact relationships, that are still unclear in literature. The fact that environmental issues and concerns are constantly changing implies that ongoing research into their influence on consumer behaviour is essential

A comparative study was performed to evaluate best practice culture media and enrichment broths for recovering salmonella species from human stool samples. A total of 1297 human stools were collected and processed in this study. Evaluation of agar media was carried out by direct plating (DP), 1096 stool samples were inoculated on Modified semisolid Rappaport-Vassiliadis (MsRV), Xylose-Lysine-Deoxycolate (XLD), MacConkey (MAC), and Hektoen Enteric (HE) agars. Evaluation of enrichment broths were carried out by enrichment all 1297 stool samples in selenite broth (sB), Rappaport-Vassiliadis (RV) broth, and Buffered Peptone Water (BPW), followed by plating on MsRV, MAC, and HE agars. A total of 102 salmonella-positive stools by DP, 85.3% (87/102) were recovered utilizing MsRV while recovery from XLD, MAC, and HE agars were 34.3% (35/102), 34.3% (35/102), and 29.4% (30/102) respectively. A total 299/1297 stools samples were salmonella-positive on at least one plating medium after enrichment procedure were 77.3% (177/299) for sB, 86.0% (197/299) and 78.6% (180/299) for RV and BPW respectively. All salmonella isolated in this study was nontyphi salmonella. Presently, the data suggest that the use of MsRV over MAC, HE, and XLD agars for isolation nontyphi salmonella species from human stools is more efficacious. Additionally, use of MsRV in combination with MAC and HE agars following enrichment in RV broth enhances recovery of nontyphi salmonella species. However, RV broth is inhibitory to typhi salmonella, thus use of MsRV medium in combination with MAC, HE or XLD agars in direct plating following enrichment in non-selective BPW is an alternate method for recovery of both typhi and nontyphi salmonella species contaminated in human stool samples.

乙烯利可以确定减少倒伏,维持或增加收获产量。1985与1986年研究了施用乙烯利比率和施用时间对玉米(Zea Mays L.)的收获产量、产量组成、倒伏与子粒品质的影响。乙烯利施于种在临近草地东北地中Pioneei杂种P_(3475)、P_(3377)和P_(3183)上。施乙烯利减少了玉米植株倒伏。P_(3377)与P_(3183)在TE时期(雄穗伸长时期)施乙烯利0.56公升/公顷者,倒伏由30％减少到9％,此比率结果使每穗少产生子粒52粒,粒重减轻7～17毫克。但是增加了收获果穗0.2～0.6个/平方米。除1986年在EE(雌穗伸长期)时施乙烯利没有影响外,增加乙烯利的施用比率,结果成线性地减少收获子粒产量。在此情况下,增施乙烯利比率,其结果是增加了每平方米收获果穗数补偿了每穗粒数与粒重的减少。1986年在TE时,两年在TE+6(雄穗伸长后6天)以及1985年在EE时施乙烯利结果是每公顷减少收获子粒产量接近1Mg(即1百万克或1千公斤)。施用乙烯利对玉米蛋白质含量,子粒的致密度和子粒易于产生破碎性有小的然面是显著的影响。施乙烯利有减少植株倒伏的作用,但它不能增加子粒产量,而且一般要减产。基于这些结果,在类似本研究的那些条件下,对栽培玉米生产者,施用一定的乙烯利,只有很小的刺激(或积极)意义。根据Zuben和Kang(1978)的估计,不管育种家怎样努力去培育抗倒伏品种,玉米茎秆倒伏年损失产量总数达5～25％。普遍认为:那些获得高产的条件:例如施高比率的氮素,高度密植,灌溉或多雨等,会促进倒伏,当发生倒伏收获子粒产量就减少(Zuben和Kang1978)。
