Seroprevalence of SARS-COV-2 Exposure among “High-Risk” Populations (Healthcare Workers, people Who Attend Markets, and School Children) in Zanzibar

Advances in Infectious Diseases 2024年第1期14卷 34-55页

作者： ame Masemo Solomon Mwakasungula Khamis Kheir Erick Mgina Nahya Khamis Irabi Kassim Bihila Bakar Khamis Salim Sarah Mswata Kibwana Omar Theckla Kazimoto Linzy Elton Honorati Masanja Mayassa Ally Zanzibar Health Research Institute Binguni Zanzibar Ifakara Health Institute Bagamoyo Tanzania National Institute for Medical Research Muhimbili Centre Dar es Salaam Tanzania Binguni Public Health Laboratory Binguni Zanzibar Department of Microbiology Mnazi Mmoja Hospital Stone Town Zanzibar Centre for Clinical Microbiology Royal Free Hospital Campus University College London London UK

In Zanzibar, from the start of the pandemic in March 2020 to the time of sampling in December 2020, SARS-CoV-2 seroprevalence data was limited. We conducted a seroprevalence study to evaluate the magnitude of SARS-CoV-2 exposure among healthcare workers, school children, and people who attended general markets in Zanzibar. The objectives of the study were to analyse the total antibodies from selected higher-risk population groups in order to determine magnitude in SARS CoV-2 exposure. Blood samples were collected from eligible and consented participants (adults and children), and their serum was analyzed for total antibodies against SARS-CoV-2 using ELISA. A questionnaire was used to collect participants’ demographic and clinical data. The overall SARS-CoV-2 seroprevalence across all age groups was 33%, and a higher seroprevalence was observed in the 40 - 49 years’ age group relative to other ages as well as in those who attended markets. A runny nose (18.8% of participants) was the most frequently reported SARS-CoV-2 infection-related symptom. Multivariable analysis showed significantly higher odds of infection in people living in urban districts. The findings provide insight into SARS-CoV-2 infection among school children, health workers, and people who attended markets in Zanzibar in the early stages of the pandemic. Exposure in these groups might have been influenced by infection and prevention strategies taken by the government, as well as shopping behavior, school overcrowding, and population density in urban settings. The study had methodological limitations, including cross-sectional design. Further, well-designed, longitudinal studies are recommended to understand exposure and transmission at a population level.

微灌在世界范围内得到广泛应用,它可以有效节省灌溉用水量,并可以提高农产品产量和质量。但是微灌也有投资费用较高的缺点。微灌主要有滴灌、微喷灌和小管出流灌（涌泉灌）等类型。其中,小管出流灌在中国北方果树灌溉（如苹果）中应用比较广泛,为保证小管出流均匀,大多安装稳流器,即通过稳流器将灌水小管与毛管连接起来;滴灌应用最为广泛,传统的孔口滴头已被压力补偿式滴头所代替,采用压力补偿式滴头可以获得很高的滴灌均匀度。滴灌管以使用方便著称,为提高灌水质量,滴灌管内镶的管上滴头也开始被压力补偿式管上滴头所替代。因此,不管是小管出流灌,还是滴灌,采用具有压力补偿式的灌水器（小管稳流器或压力补偿式滴头）均具有较好的前景。然而目前在微灌系统设计中,针对采用压力补偿式灌水器的毛管设计还缺乏科学合理的方法。干、支管由于有明确的设计流量,可以利用经济流速,确定合理的经济管径。但是对于毛管而言,由于毛管从首端到末端,其流量是变化的,其流速也是变化的,因此不能采用经济流速确定其合理管径。按目前的设计方法,采用压力补偿式灌水器时,一般是根据水力准则的相关规定确定毛管的管径,也就是只需满足毛管上各灌水器（小管或滴头）的工作压力都在允许的工作压力范围内,即工作压力不小于最小工作压力,且不大于最大工作压力。然而有些压力补偿式灌水器的允许工作压力范围很大（达5m～40m水头）,在实际设计中,可能会出现采用多种不同管径（如De12、De26、De20等）都满足水力准则的情况。此时就存在如何具体选择管径的问题,若采用管径较小的毛管,则管材投资较小,但因水头损失增加,运行能耗费用较大;反之,若采用管径较大的毛管,则管材投资较大,运行能耗费用会较小。本文旨在解决这一实际问题,即在毛管设计中,在安装压力补偿式灌水器的情况下,如何在满足水力准则的条件下根据经济准则（即综合成本费用最小）来确定毛管经济管径。1.研究内容与优化原理（1）研究内容在微灌系统中,毛管管径较小,单价较低,但因为数量很多,其成本在工程总成本费用中仍占很大比例。因此,为了节省总成本费用,研究毛管的经济管径也十分重要。鉴于上述实际需要,本文系统研究毛管单元的总成本费估算方法,以年成本费用最小为目标,分别针对采用稳流器的小管出流灌溉系统和采用压力补偿式滴头的滴灌系统的毛管,分析其在各种可能情况下的经济管径,从而为这类微灌系统毛管设计提供有益参考。（2）优化原理以总成本费用最小为目标,以管径为决策变量,以压力补偿式灌水器的允许工作压力范围为约束条件（水力准则）。毛管管径（d）是离散变量,毛管管径种数（n）有限。小管出流可选用毛管管径主要De12、De16、De20和De25等4种,滴灌可选用毛管管径有De12、De16和De20等3种,因此拟采用枚举法确定最优管径。针对典型的小管出流灌溉系统或典型的滴灌系统,拟定灌水器流量（q）、毛管长度（L）和灌溉定额（W）和毛管管径（d）的各种可能的组合。然后分别计算投资成本（Cc）、运行成本（C0）及年化总成本费用（Ct）,并进行优选,最终得到不同可能组合条件下毛管的最优管径。优化方法原理如图1所示。考虑到小管出流多用水于果树,毛管布置在有一定坡度的坡地上的可能性较大,因此对于小管出流毛管优化分析,还考虑了各种可能的地面坡度。图1优化原理框图2.微灌毛管成本分析与目标函数（1）小管灌溉系统的布局小管出流灌溉一般用于果树灌溉,该系统包括泵送装置、过滤器、干管、支管、毛管和小管。干管从水源供水并将其输送到支管,支管将水输送到毛管和小管（灌水器）。小管通过稳流器连接到毛管,并将水灌入根区周围的渗透环沟。（2）毛管成本管道的完整成本是管道材料、长度和直径的函数。对于给定类型、给定管径的管道,管道的资本成本与仅其长度成正比,即:CP=LP 1式中,Cp为管道资本成本（$）;L为毛管长度（m）;P为管道价格（$/m）。（3）泵的成本加压水泵以及所有附件和安装费用的成本CP为其功率P的函数,可表示为Cp=KpPmp 2式中,Kp为系数;mp为指数;P为电机功率（kW）。电机功率P取决于泵的流量和扬程,计算公式为:P=ρgQh0/10000η 3式中,Q为泵的流量（m3/s）;h0为水泵扬程（m）;ρ为水的质量密度（g/cm3）;g为重力加速度（m/s2）;η为泵和电机单元的效率。（4）能耗成本灌溉系统的年度能源消耗取决于年度灌溉需求和抽水所需的功率。这个年度能源消耗可以通过将电动机功率乘以一年中水泵抽水天数（D）及平均每天工作小时（T）数来估算,计算式为:Aen=DTρgQh0/1000η 4年度运营成本需转换为现值:Cop=AenCen（A/P,i,n）5式中,Cop为年运营成本（$）;Aen为年能源需求（$）;Cen为能源价格（$/kW·h）;（A/p,i,n）为资本回收系数。即（A/P,i

基于我国2007—2019年30个省级区域的面板数据,建立空间计量模型分析科技创新投入和教育水平对于区域经济增长的影响。结果表明:东南沿海地区发展较好,并且表现为经济发达省份被其他经济发达的省份包围的分布态势;西部地区大多为经济欠发达省份,并且周围的省份经济发展也较差。通过分析得出科技创新投入对区域经济增长存在显著的正向溢出效应,但是教育水平对区域经济增长的溢出效应不显著。在中国经济进入高质量发展阶段,需要加强省份间经济合作,明确政府自身定位,提高科技创新投入水平和科技创新成果转化能力,推进教育水平综合提升。

Sketches toward a Theory of Every Thin/kin/g

Journal of Philosophy Study 2013年第8期3卷 685-705页

作者： ame Kjellman Researcher Department of Computer and Systems Sciences Stockholm University and KTH Sweden

The status of the social and human sciences as genuine sciences on a par with the natural sciences has widely been held in doubt, and the subject-oriented approach （SOA） to knowledge also shows the traditional scientific view to be misleaded. Its shows that it is mandatory to dismiss the idea that personal knowledge is a representation of a common world created by some God, and also the mistake to take the seductive noun/verb structure as for given. We need a new methodological paradigm of science--an approach that avoids the pitfalls of dualism and realism--and take the effort to couch its thinking in a re-interpretation of natural language. This line of reasoning paves the way for the SOA--a new epistemology that takes the individual knower and its feelings as the coherent point of departure. The traits of a new foundation are sketched and to that end a bootstrap model is proposed that departs from the early man＇s first experience. In doing so, we, in a subject-oriented manner, can bring man＇s living experience and his priverse （or private universe）, under the collective umbrella of a consensual science. This approach brings the promise to provide a sound theory of everything-or rather a theory of every thin/kin/g-which in one step removes the cleft between the natural and social sciences.

Accounting and the ＂Doctor-Manager Relationship＂

Journal of Modern Accounting and Auditing 2013年第4期9卷 489-496页

作者： ame.ia Cristina Ferreira-da-Silva Jose Manuel T. pereira Humberto Nuno Rito Ribeiro Polytechnic Institute of Porto Porto Portugal Jose Manuel T. Pereira Polytechnic Institute of Caivado and Ave Barcelos Portugal Polytechnic Institute of Braganca Braganga Portugal

The adoption of the ＂new public management＂ in the hospital sector brought about greater presence and power to professional managers in hospitals, thus increasing the risk of conflict in the doctor-manager relationship. Aiming to enrich the discussion on the factors that could be the bases for this conflict and considering the role of accounting, the study presented here corresponds, basically, to what we call ＂content analysis＂ of qualitative studies. The results demonstrate that the Portugue.e doctors as the sample studied accept, in essence, the principles of enterprise management and recognize the use of accounting information in the scope of their functions as long as they are called to participate as legitimate actors, and authorities respect their desires to preserve a practice which they consider of quality.

克氏原螯虾（Procambarus clarkii）是中国最重要的经济型水生甲壳动物之一,养殖产量高,具有重要经济价值。20世纪20年代从日本引进入中国南京,目前已成为中国分布最广、最著名的淡水经济甲壳动物养殖品种之一。克氏原螯虾抗病能力强、繁殖力强、生长速度快、养殖周期短、适应性强,这些特性使其在新环境的中很容易生存,具有很高的市场需求和经济价值。2018年4月底5月初盱眙县兴隆乡池塘养殖的克氏原螯虾大量死亡,致病原因不明,本研究旨在找出并鉴定克氏原螯虾养殖场暴发的病原。本研究采用聚合酶链反应（PCR）检测和鉴定克氏原螯虾肝脏中的病毒,并采用透射电镜（TEM）技术研究克氏原螯虾鳃组织形态。PCR检测了两个不同的病毒带,即200bp的WSSV带和150bp的未知病毒带。然后利用透射电镜对病毒的形态进行研究。透射电镜证实了病小龙虾鳃中存在大量两种不同的病毒颗粒。病毒颗粒的形态和大小不同。其中一个颗粒呈棒状,有囊膜包被,长约300nm,鉴定为白斑综合征病毒（White spot syndrome virus,WSSV）。WSSV可导致克氏原螯虾患白斑病。另一种病毒外观为球形,无囊膜,直径约30nm,鉴定为小RNA病毒成员。这是一种新的病原。我们将这种新的小 RNA 毒命名为 PcPV（Procambarus clarkiipicorna-like virus）。通过Genbank和分子进化遗传学分析（Mega）软件6.0版,将采用高通量测序技术获得PcPV的基因序列与其他21个小RNA病毒目病毒进行比较分析并构建进化树,分析发现,该病毒序列与未分类的Beihaipicornalike virus病毒105株BHHK79817有75%的遗传同源性,应属小RNA病毒目小RNA病毒科的一个新属。本研究发现,100%的养殖克氏原螯虾PcPV检测为阳性,只有62.5%的养殖克氏原螯虾（15/24）WSSV检测为阳性,37.5%的养殖克氏原螯虾（9/24）WSSV检测为阴性。南泉市健康克氏原螯虾100%PcPV检测为阴性,75%WSSV检测为阳性。我们得出的结论是,该农场的疾病暴发不仅是由于WSSV,PcPV在很大程度上促成了该疾病暴发。新发现的PcPV是克氏原螯虾的新病原。有关于克氏原螯虾PcPV的组织病理学效应和死亡率的研究还需进一步开展。
