Megacity pathways in China under the dual carbon goal:The case of Shanghai

The pathways to achieving carbon neutrality at the city level are diverse due to varying energy supply and demand conditions.Shanghai faces obstacles such as limited land resources,high costs of renewable energy technologies,and instability of renewable energy.These challenges hinder the city’s efforts to achieve carbon peak and carbon neutrality(dual carbon).Therefore,Shanghai must identify and optimize its development path for renewable energy under the dual carbon goal.We employed the Low Emissions Analysis Platform Shanghai(LEAP-SH)model to simulate the impact of policies,such as industrial upgrading,energy efficiency improvement,energy structure optimization,increased technical innovation on energy,and ecological restoration,on the carbon emission pathways from 2022 to 2060 using five different scenarios.Our results indicate that Shanghai has the potential to achieve carbon neutrality in 2059 by promoting carbon reduction,pollution control,and green expansion.Moreover,we determined that the manufacturing industry;power generation industry;and transportation,storage,and mail services are the three major sectors for emission reduction under the dual carbon goal.Furthermore,the capacity and output of coal-fired power plants will be gradually replaced by offshore wind power in the dual carbon pathway.Finally,this study proposes countermeasures and suggestions for Shanghai to attain the dual carbon goal and high-quality development.

The 2022 Extreme Heatwave in Shanghai,Lower Reaches of the Yangtze River Valley:Combined Influences of Multiscale Variabilities

In the summer of 2022,China(especially the Yangtze River Valley,YRV)suffered its strongest heatwave(HW)event since 1961.In this study,we examined the influences of multiscale variabilities on the 2022 extreme HW in the lower reaches of the YRV,focusing on the city of Shanghai.We found that about 1/3 of the 2022 HW days in Shanghai can be attributed to the long-term warming trend of global warming.During mid-summer of 2022,an enhanced western Pacific subtropical high(WPSH)and anomalous double blockings over the Ural Mountains and Sea of Okhotsk,respectively,were associated with the persistently anomalous high pressure over the YRV,leading to the extreme HW.The Pacific Decadal Oscillation played a major role in the anomalous blocking pattern associated with the HW at the decadal time scale.Also,the positive phase of the Atlantic Multidecadal Oscillation may have contributed to regulating the formation of the double-blocking pattern.Anomalous warming of both the warm pool of the western Pacific and tropical North Atlantic at the interannual time scale may also have favored the persistency of the double blocking and the anomalously strong WPSH.At the subseasonal time scale,the anomalously frequent phases 2-5 of the canonical northward propagating variability of boreal summer intraseasonal oscillation associated with the anomalous propagation of a weak Madden-Julian Oscillation suppressed the convection over the YRV and also contributed to the HW.Therefore,the 2022 extreme HW originated from multiscale forcing including both the climate warming trend and air-sea interaction at multiple time scales.

Status,outcome,and related factors of postpartum hypertension in the Shanghai community

BACKGROUND Postpartum hypertension poses a considerable health risk.Despite research on gestational hypertension,comprehensive studies focusing on postpartum hypertension in communities are limited.Understanding its prevalence and associated risk factors is crucial for effective prevention and management.AIM To provide insights for postpartum hypertension’s prevention and management.METHODS In total,3297 women who gave birth between June 2021 and December 2022 in Xuhui District,Shanghai were selected.Blood pressure was measured thrice within one month post-delivery during home visits.Eighty-six women with hypertension were followed up for four months to analyze hypertension persistence and its related risk factors.A predictive model for persistent postpartum hypertension was established and verified using the Nomo diagram model.RESULTS Hypertension prevalence 1 month post-delivery was 2.61%(86/3297).Among the 86 pregnant women,32(37.21%)had persistent hypertension at four months post-delivery.Multivariate logistic regression analysis revealed that older age[odds ratio(OR)=1.212;95%confidence interval(CI):1.065–1.380]and higher pre-pregnancy body mass index(BMI)(OR=1.188;95%CI:1.006–1.404)were associated with hypertension(OR=10.781;95%CI:1.006–1.404)during pregnancy.A 95%CI of 1.243–93.480 is a risk factor for persistent postpartum hypertension.The Nomograph model accurately predicted the risk of persistent postpartum hypertension,demonstrating high precision.CONCLUSION In Xuhui,older age,higher pre-pregnancy BMI,and gestational hypertension are risk factors for persistent postpartum hypertension.Our prediction model can identify high-risk individuals,thereby improving patient quality of life.

The biosafety level-2 macromolecular crystallography beamline(BL10U2)at the Shanghai Synchrotron Radiation Facility

BL10U2 is an undulator-based macromolecular crystallography(MX)beamline located at the 3.5-GeV Shanghai Synchrotron Radiation Facility.BL10U2 is specifically designed for conducting routine and biosafety level-2(BSL-2)MX experiments utilizing high-flux tunable X-rays with energies from 7 to 18 keV,providing a beam spot size of 20μm(horizontal)×10μm(vertical)at the sample point.Certification by the Shanghai Pudong Municipal Health Commission confirmed the capability to perform BSL-2 MX experiments.The beamline is currently equipped with an Eiger X 16 M detector and two newly developed in-house high-precision diffractometers that can be switched to perform conventional or in situ crystal diffraction experiments.An automatic sample changer developed in-house allows fast sample exchange in less than 30 s,supporting high-throughput MX experimentation and rapid crystal screening.Data collection from both the diffractometer and detector was controlled by an in-house developed data collection software(Finback)with a user-friendly interface for convenient operation.This study presents a comprehensive overview of the facilities,experimental methods,and performance characteristics of the BL10U2 beamline.

BL02U1:the relocated macromolecular crystallography beamline at the Shanghai Synchrotron Radiation Facility

Macromolecular crystallography beamline BL17U1 at the Shanghai Synchrotron Radiation Facility has been relocated,upgraded,and given a new ID(BL02U1).It now delivers X-rays in the energy range of 6–16 keV,with a focused beam of 11.6μm×4.8μm and photon flux greater than 1012 phs/s.The high credibility and stability of the beam and good timing synchronization of the equipment significantly improve the experimental efficiency.Since June 2021,when it officially opened to users,over 4200 h of beamtime have been provided to over 200 research groups to collect data at the beamline.Its good performance and stable operation have led to the resolution of several structures based on data collected at the beamline.

沿江型湿地公园景观环境特征对人群自然感知及感知复愈性的影响——以上海后滩公园为例

丰富的自然体验与感知有利于发挥绿地的健康效益,明确影响滨江人群自然感知及感知复愈性的景观环境要素对于精细化提升公园绿地环境品质具有重要意义。以典型沿江型湿地公园上海后滩公园为例,采用游客受雇佣拍摄法,获得景观环境感知特征数据及感知自然程度和感知复愈程度评分数据,探索与人群自然感知及感知复愈性相关的公园绿地景观环境影响要素。研究发现:1)场景内存在水体、植被物种丰富度越高、视觉主体植被健康程度越高、场地的整洁程度越高、无硬质铺地道路或道路类型为线性延伸路径,对人群的自然感知程度和感知复愈程度更有利;2)场景内有动物出现、人工修剪痕迹更少会显著提升人群对自然的感知程度,但与人群的感知复愈程度相关性不显著;3)场景内的土地裸露度会负向影响公众在自然中的复愈感受,而对人群的自然感知程度无显著影响。基于以上研究结果,对沿江型湿地公园景观环境提出设计优化建议:1)增加水体要素;2)提高植被物种丰富度;3)提高场景整洁度,降低土地裸露度,同时也须避免对植被的过度修剪;4)营造丰富生境,提高野生动物多样性及其可观测性。

Sora:作为世界模拟器的“天空”媒介

目前,关于文生视频人工智能应用Sora的分析存在两个极端:过于内行的技术分析,让人云里雾里;过于外行的“炸裂”分析,让人惊恐不已。从媒介学、传播学和新闻学角度分析Sora,可以发现,它同时属于超级媒介、基础设施型媒介、冷/热媒介、贫/富媒介、新/旧媒介、真/假媒介。Sora证明了物理规律的强大和现实的坚韧,能“画出不可画者”,朝着元宇宙方向迈进。在人工智能的重重包围和步步逼近下,在人类创造力的顶峰,红旗仍将高高飘扬;在各种虚拟现实技术盛行的今天,新闻业更应坚守现实本身,此时,机构型媒体作为信源的品牌公信力将变得更加重要。

魔都印象:基于文本分析的上海城市旅游情感形象研究

情感形象是旅游目的地重要形象之一。以外地游客的上海游记为语料,采用扎根理论研究法、内容分析法分析外地游客对上海旅游目的地的情感态度。结果表明:①游客对上海旅游目的地的情感态度总体上积极正面,体现在旅游吸引物、休闲娱乐、设施服务、环境氛围和管理服务5个维度上;②游客对上海旅游目的地的积极评价多集中在“繁华、现代、时尚、独特”高频词上,说明世界著名旅游城市形象已基本建成;③但是景区商业化、高物价和人多排队等因素带给部分游客负面情绪。针对此,本文提出了夯实景区文化内涵、加快全域旅游建设、加大宣传力度、加大精细化服务管理等提升城市旅游形象的建议。

城市的新景观、诗学隐喻与修辞语言——论小说、舞台剧和电视剧《繁花》

金宇澄的小说《繁花》采取了图文并茂的方式来表现上海的城市空间,被认为是最好的表现上海的“城市小说”,舞台剧、电视剧《繁花》则通过舞台和影像直观地展现了上海的城市新景观。在舞台剧《繁花》中,导演马俊丰运用转台、多演区、多媒体等手段来展示舞台的假定性、空间性和意象性。电视剧《繁花》则拍出了20世纪80年代,尤其是90年代后的上海这个魔都的魅力。导演王家卫没有完全按照小说、舞台剧的散点式来结构,而是围绕着阿宝的焦点展开叙述,因此将电视剧《繁花》拍成了电影,或者说上升到了电影的高度。这也可以说是电视剧《繁花》的美学意义。
