Affogatos are probably one of my fave treats. During my recent visit, decided to try something different. There's the affogato and then there's Home's Cookie Monster-gato which sounded very interesting. Essentially it's the affogato with cookie butter and little cookie cereal. Barista stated that the cookie butter makes the espresso creamier. Decided to try it. OMG!!! Sooo good! Definitely creamier and such a decadent treat. Daughter got one too. She offered some to her dad who initially declined but then took one taste and finished it off. Needed to order another one. As I write this, I'm already craving another one.
I would say this place is averagely good. Obviously the drinks are decorated very well but I wouldn't say the flavors are anything special. I was excited to try this place based on the reviews and photos but I have to say I was sort of let down. Nevertheless, the drinks didn't taste bad and I got the fix of coffee that I needed. We ordered the Birthday Cake latte (hot) and Cookie Monster latte (iced). Both were ok, the Cookie Monster had a little bit more flavor because of the cookie butter at the bottom, but still I feel this place is mainly focused on making the drinks looks pretty, and they are definitely succeeding in that respect. Overall, I don't think I will return but if you are looking for pretty lattes to post on social media this is definitely the place for you!
Updated review for Oct 2021. No indoor seating or public bathrooms available. To-go ordering only. Coffee quality is still great, but sad indoor dining still wasn't available despite many other areas re-opening up partially/completely. If one is looking for indoor cafe seating, walk a few blocks down to Henry's coffee house where indoor/outdoor patio is available.
Excellent iced salted caramel latte and Bravo egg avocado toast!! Excellent workers and food. Happy I tried this coffee spot today!! |

无意中发现的店,一直躺在收藏夹里,工作日的下午跟朋友特意过去打卡,下雨天,人还是不少,室内室外都能坐,先找位置,然后桌上二维码扫码点单的!我们先逛了一圈,很多小姐姐都在拍照,还有个草坪,天气好的时候拍照会很出片!南瓜汤:味道浓郁,略浓稠的汤,上面撒的杏仁粒很香很脆!下次准备再去,吃点别的!
风和日丽的日子,总是热闹的,野餐、遛狗,喝咖啡~~ 一尺花园,古色古香的中式老房子与西式美食、咖啡结合别有特色,周末人太多了有点遗憾。在这里不迷恋他家的咖啡,居然是别人家的狗狗,萌宠治愈心情,阳光下草地上都好可爱哦。
夏天的时候一家子到川沙玩,打卡了川沙网红一尺花园。一进大门就小池鲤鱼,再往里走,大厅有好几个艺术雕像。 我们是下午到的,先点了茶饮料咖啡·蛋糕乡,都挺好吃,但是大厅太热,空调不足,我一直汗哒哒滴。 外面有很大草坪花园,很多人带着孩子或者毛孩子在外面奔跑,我害怕太阳,没有出去逛。 我们坐到晚上,服务员给我换了一间房,空调足了,点了个套餐,解决了晚餐。 总体环境意境不错,适合拍照打卡,晚餐不如下午茶,东西太咸。
马上要降温了,又不能出沪,赶着最后的暖冬带孩子出来玩 这家一尺花园陶家宅亻号店就在我们住的酒店隔壁,因为本身就是一个百年宅邸,也是酒店的宣传卖点之一,预定酒店赠送 了两张咖啡券,于是就想着不行到这边喝杯咖啡。 环境确实不错,门口有个草坪草坪里还有个沙坑很受小朋友的欢迎,至于滑滑梯等玩乐设施早就封底熬了,上面用绳子拦 着写着设施故障啥的,反正就是给人年久失修没人维护的破落感。一开始进去点咖啡,服务员看我拿的是酒店赠送的券,很有点不耐烦的感觉,咖啡甜品单价都挺高,这个新品杏仁慕斯我觉得甜了点,后来家里人来了想想也懒得开车出去,就干脆在这里点了中午正餐,味道还不错,牛肉不老当然价格也是很高,面包酥脆挺入味,不过总的来说性价比一般。户外座位确实挺紧俏,几乎坐满,想想如果不是住店,专门跑那么远来喝杯咖啡,我也是挺佩服的,换我是不太会。

https://en.wikipedia.org/wiki/For_Beginners
The For Beginners series was launched in the mid-1970s, but became out of print and often unavailable after the 2001 death of co-founder and publisher Glenn Thompson. In 2007, a consortium of investors revived the series, reprinted back issues, and promised to publish between six and nine new issues each year. The current publisher is Dawn Reshen-Doty.

1.3 设定文件存储目录
#dataforder是文件目录,同学可以自行修改你的文件目录,注意两点
#(1)不能用汉字,必须是英文字母和数字的组合
# (2) window系统,目录用\,而这里用的跟苹果系统、linux系统一致的/,需要修改一下
# 对于一个行数很多的程序,用起来很方便。
datafolder="D:/tdata/"
1.4 文献数据检索Bibliographic Collection
web of science数据库: 关于该数据库及创始人,参见http://kaiwu.city/index.php/histcite
web of science数据库官方网址(购买了授权,校园网可以访问) http://apps.webofknowledge.com/

1.5导入文献计量分析数据Data Loading and Converting
first file 1-500
# 导入bib格式的文献数据Loading txt or bib files into R environment
# 方法1:如果已经下载了文献数据,可以使用本地文件
D1<- paste0(datafolder,"wos_bigdata1.bib")
# 方法2:直接使用网盘分享连接,下载并导入
# 网盘链接1:国外网盘opendrive.com
# D1 <-"https://od.lk/s/172672726_f1pd3/wos_bigdata1.bib"
# 网盘链接2:国内网盘https://www.ctfile.com/
# D1 <-"https://drfs.ctcontents.com/file/20727931/557190835/131a5c/opendata/wos_bigdata1.bib"
# bib格式数据转换为R分析用数据格式
# Converting the loaded files into a R bibliographic dataframe
M1 <- convert2df(file = D1, dbsource = "isi", format = "bibtex")
Converting your isi collection into a bibliographic dataframe Done! Generating affiliation field tag AU_UN from C1: Done!
second file 501-699
# Loading txt or bib files into R environment
D2 <- paste0(datafolder,"wos_bigdata2.bib")
# D2<-"https://od.lk/s/172672727_ACXwn/wos_bigdata2.bib"
# D2<-"https://drfs.ctcontents.com/file/20727931/557190837/f586ff/opendata/wos_bigdata2.bib"
# Converting the loaded files into a R bibliographic dataframe
M2 <- convert2df(file = D2, dbsource = "isi", format = "bibtex")
Converting your isi collection into a bibliographic dataframe Done! Generating affiliation field tag AU_UN from C1: Done!
# 合并导入的两个文件M1和M2
# 因为列结构相同(47个变量),只是行数的合并,所以用rbind,r表示row
# 如果行数是一样的,只是增加变量,那就是列合并,cbind,c表示column
# 如果是数据库的不同表格合并,那你要用merger,join,要设置合并的主键
M699<-rbind(M1,M2)
1.6 保存数据
# 将处理好的数据文件保存,以便未来使用——不用每次都重新导入原始数据
# csv是用英文逗号(,)作为分隔符号的数据格式,可以直接用excel打开,几乎所有的数据分析软件都支持csv格式数据
# rda是r特有的数据格式
write.csv(M699, file = paste0(datafolder,'M699.csv'))
save(M699,file=paste0(datafolder,'M699.rda'))
#save(M699,file='D:/tdata/M699.rda')
清理缓存clear the memory
1.7 剔除两条重复记录
3.1 部分 NetMatrix699 <- biblioNetwork(M699, analysis = "co-citation", network = "references", sep = ";")
出错,错误信息如下
Warning message: "non-unique value when setting 'row.names': 'QIU Q, 2021, ISPRS INT J GEO-INF'" Error in .rowNamesDF<-
(x, value = value): duplicate 'row.names' are not allowed Traceback:
- biblioNetwork(M699tag, analysis = "co-citation", network = "sources",

- cocMatrix(M, Field = "CR_SO", type = "sparse", n, sep, short = short)
row.names<-
(*tmp*
, value = M$SR)row.names<-.data.frame
(*tmp*
, value = M$SR).rowNamesDF<-
(x, value = value)- stop("duplicate 'row.names' are not allowed")
#剔除重复记录
M699 <- subset(M699,SR !='QIU Q, 2021, ISPRS INT J GEO-INF')
1.8 再次保存数据
# 将处理好的数据文件保存,以便未来使用——不用每次都重新导入原始数据
# csv是用英文逗号(,)作为分隔符号的数据格式,可以直接用excel打开,几乎所有的数据分析软件都支持csv格式数据
# rda是r特有的数据格式
write.csv(M699, file = paste0(datafolder,'M699.csv'))
save(M699,file=paste0(datafolder,'M699.rda'))
#save(M699,file='D:/tdata/M699.rda')
rm(list=ls())
2.描述性统计分析
以后的数据分析,可以直接从2.开始,需要再次设定一下
# 调用bibliometrix拓展功能包
library(bibliometrix)
# 设定工作文件夹
datafolder="D:/tdata/"
导入数据
load(file=paste0(datafolder,'M699.rda'))
# load(file=url("https://od.lk/s/172672725_Ma5xJ/M699.rda"))
# load(file=url("https://drfs.ctcontents.com/file/20727931/557191120/aaffe1/opendata/M699.rda"))
文献计量学(bibliometrics)主要以量化科学产出和评估科研成果影响而闻名,也可用于展示研究的动态演变。通过这种方式,文献计量学旨在描述特定学科、或研究领域的结构以及它们如何随时间演变。换言之,文献计量方法有助于绘制科学图谱(science mapping),并且在综合多个研究方面意义较大。文献计量学是建立在一套统计方法之上的一个学科,可用于定量分析科学大数据及其随时间的演变并发现信息。网络结构通常用于对作者、论文/文档/文章、参考文献、关键字等之间的交互进行建模。
Bibliometrix 是一个开源软件,用于自动化数据分析和数据可视化。在 R中转换和上传文献数据后,Bibliometrix 执行描述性分析和不同的研究结构分析。描述性分析提供了一些关于年度研究发展、前“k”位高产作者、论文、国家和最相关关键词的快照。

3. 共被引用分析 Co-citation Analysis
引文分析(Citation analysis)是文献计量学(bibliometrics)的经典技术之一。它通过节点(例如作者、论文、期刊)之间的联系显示特定领域的结构,而边缘可以根据网络类型进行不同的解释,即共同被引、直接引用、书目耦合。请参阅 Aria,Cuccurullo (2017)。 Aria, M., & Cuccurullo, C. (2017). bibliometrix: An R-tool for comprehensive science mapping analysis. Journal of Informetrics, 11(4), 959–975. https://doi.org/10.1016/j.joi.2017.08.007
下面是三个例子。
首先,被引参考文献(节点)之间关系的共引网络(co-citation networks)。
其次,使用被引期刊作为分析单位的共引网络。
评论共引网络的有用维度是:(i)节点的中心性和外围性 centrality and peripherality of nodes,(ii)它们的接近度和距离their proximity and distance,(iii)联系强度strength of ties,(iv)聚类clusters,(iiv)展示研究贡献之间的关系bridging contributions。
第三,引文编年图(historiograph)是建立在直接引用的基础上的,它按照历史顺序绘制了研究成果间的联系,足以重建该领域的发展历程,呈现该领域的里程碑式的重要研究。

5. 概念图结构:共词分析The conceptual structure - Co-Word Analysis
共词网络(Co-word networks)显示概念结构,通过术语共现(term co-occurences)揭示概念之间的联系。概念结构通常用于理解学者所涵盖的主题(研究前沿research front),并确定哪些是最重要和最近的问题。将整个时间跨度划分为不同的时间片(timeslices),并比较概念结构,有助于分析主题随时间的演变。
Bibliometrix 能够分析关键词,也可以分析文章标题和摘要中的术语。 它使用网络分析或对应分析(correspondance analysis,CA)或多重对应分析(multiple correspondance analysis,MCA)来完成。 CA 和 MCA 在二维坐标系中可视化概念结构。
5.1 共词分析:基于关键词的共同出现
Co-word Analysis through Keyword co-occurrences
Plot options:
-
normalize = "association" (the vertex similarities are normalized using association strength)
-
n = 50 (the function plots the main 50 cited references)
-
type = "fruchterman" (the network layout is generated using the Fruchterman-Reingold Algorithm)
-
size.cex = TRUE (the size of the vertices is proportional to their degree)
-
size = 20 (the max size of the vertices)
-
remove.multiple=FALSE (multiple edges are not removed)
-
labelsize = 3 (defines the max size of vertex labels)
-
label.cex = TRUE (The vertex label sizes are proportional to their degree)
-
edgesize = 10 (The thickness of the edges is proportional to their strength. Edgesize defines the max value of the thickness)
-
label.n = 30 (Labels are plotted only for the main 30 vertices)
-
edges.min = 25 (plots only edges with a strength greater than or equal to 2)
-
all other arguments assume the default values
