Past, present, and future of knowledge management for business sustainability
گذشته، حال، و آینده مدیریت دانش برای پایداری کسب و کار-2021 Knowledge management has gained increasing importance and immense research interest for its promise in
advancing sustainability. Despite its proliferation in the literature, little is known about the research profile of
knowledge management research intertwined with sustainability. Given this gap, this article aims to conduct an
extensive review of knowledge management for sustainability research. Using bibliometrics, which is suitable for
large-scale reviews, this article reviews 1136 documents published in peer-reviewed journals indexed in the Web
of Science between 2001 and 2021. Noteworthily, the review sheds light on the performance of research con-
stituents (e.g., most prolific authors, countries, institutions, and journals), as well as the themes and topics
underpinning the intellectual structure (i.e., knowledge foundation, knowledge creation) in the field. Specif-
ically, the review reveals that knowledge management for sustainability research has relied on nine foundational
clusters (i.e., informed sustainability practice, social network, firm performance, knowledge sharing culture,
green innovation, sustainability assessment framework, global warming, knowledge management, and innova-
tive performance) to generate new knowledge across 10 thematic clusters, (i.e., ecological knowledge, green
innovation, the Shanghai Hongqiao district effect, the Agroscope Research Master Plan, food security, sustainable
supply chain management, business sustainability, knowledge creation, knowledge management, and technology
management). The article concludes with a new theory that encapsulates extant understanding of knowledge
management for sustainability along with promising avenues for future research. keywords: مدیریت دانش | پایداری | بررسی ادبیات | تجزیه و تحلیل کتابشناسی | Knowledge management | Sustainability | Literature review | Bibliometric analysis |

Nine-nine-six work system and people’s movement patterns: Using big data sets to analyse overtime working in Shanghai
سیستم کار نه-نه-شش و الگوهای حرکت مردم: استفاده از مجموعه داده های بزرگ برای تحلیل اضافه کاری در شانگهای-2020 Although topics regarding “996 work system” and overtime working have aroused hot arguments, there is scant
literature that analyses the spatial distribution and movement patterns of people who work overtime. This article
fills this gap by adopting big data analysis and examining the mobile phone signal data which allow the calculation
of the approximate spatial position of the mobile-phone user, and the generation of transportation flows
and individuals’ origin-destination (OD) flows. The findings show that no less than one third of employees in
Shanghai work overtime, and that overtime workers face higher job-housing imbalance than workers who have
normal work durations or flexible schedules. This corroborates David Harvey’s time-space compression theory.
Going beyond that, we further discover the interchangeability between exploitation in the time dimension, and
that in the spatial dimension, resulting in dual exploitation. This article has important policy implications for
optimizing the urban spatial system of Shanghai, as it advocates that in addition to strengthening the enforcement
of labor law, the government also needs to improve the public service such as strengthening the underground
system’s capacity, and construct affordable houses, so as to alleviate the employees’ sufferings caused by
temporal and spatial exploitation. Moreover, the research points out the necessity for Chinese cities to enhance
the vertical mixing, in order to shorten the job-housing distance. Keywords: Overtime working | Human activity patterns | Big data | Mobile phone Signal data | Shanghai | OD | Time-space compression | Vertical mixing of land use |

A retrospective analysis of data from forensic toxicology at the Academy of Forensic Science in 2017
تجزیه و تحلیل گذشته نگر از داده های مربوط به سمیت شناسی پزشکی قانونی در آکادمی علوم پزشکی قانونی در سال 2017-2019 Knowing the specific pattern of forensic toxicology cases in a region is vital to help the local government
establish an effective prevention and treatment system; currently, there have been no published reports
investigating various types of forensic toxicology cases based on a large autopsy series and city size. The
data in this study were obtained from records kept at the Academy of Forensic Science (AFS) between
February 2017 and December 2017, and the cases were mainly from the Public Security Organs People’s
Police in Shanghai, China. There were 299 autopsies; the leading cause of death was traffic accidents
(37.1%), and the manners of death were mainly accidental (54.8%). From a total of 9083 cases, 1992
involved traffic accidents, 6787 were drug abuse, 269 were poisonings, and 35 were drug-facilitated
sexual assaults (DFSAs). We also investigated the pattern of unnatural deaths and the alcohol-positive
(with a blood alcohol concentration (BAC)
0.20 mg/ml) rate among the various cases. The BAC ranged
from 0.08 to 7.24 mg/ml in traffic cases, and the mean BAC of the total alcohol-positive drivers was
1.44 mg/ml. It was found that 80.8% of the drivers involved had a BAC
0.20 mg/ml (limit of civil offense),
and 72.8% had a BAC
0.80 mg/ml (limit of criminal offense). Among the drug abuse cases, there were
4073 cases (60.0%) that were positive for at least one euphoriant; the most frequently abused drug group
was amphetamine-type stimulants (ATS). Poisonings by natural toxins (such as scopolamine and
tetrodotoxin) account for a significant portion of accidental deaths. Pesticide poisoning was also
constituted a large portion, and organophosphorus were the cause of the majority of those cases. Suicide
by pesticide showed the highest frequency in the present study. Among the 35 DFSA cases,
dexmedetomidine was frequently detected in our study, which has rarely been reported previously
in DFSA cases. Keywords: Driving | Drug abuse | Poisoning | Drug-facilitated sexual assault | Retrospective study | Shanghai |

Infant deaths in Pudong, Shanghai, China: A retrospective study of the police data and comparison with the centre for disease control data
مرگ و میر نوزادان در پودونگ ، شانگهای ، چین: یک مطالعه گذشته نگر از داده های پلیس و مقایسه آن با مرکز کنترل داده های بیماری-2019 In China, every year many infants (< 1 year) are abandoned, but abandonment related deaths are rarely reported.
In this study, the police records of infant deaths in Pudong, Shanghai have been explored, then, the
police data were compared with the corresponding Centre for Disease Control (“CDC”) data. During the period
2004–2017, a total of 297 infant deaths were recorded by the police, including 87 sudden natural deaths (occurred
outside hospitals) and 210 unnatural deaths. The CDC data were retrieved from a Chinese article.
Joinpoint Trend Analysis was used to evaluate the trend of the police records on infant deaths, and Poisson
regression was used to calculate the mortality rate ratio (“RR”) by gender and places of origin (local, migrant,
unknown identity). It is observed that infants born to migrant mothers were more vulnerable to sudden natural
deaths than their local counterparts (RR: 4.6, 95% CI: 2.8 to 8.1). 8 abandonment deaths and 187 suspicious
abandonment deaths were spotted. Births to unmarried mothers, severe illnesses, and deformities could be
important risk factors resulting in abandonments. However, the female gender was not a reason that led to the
abandonments. Infant deaths related to abandonments/suspicious abandonments rapidly declined during the
period 2004–2017. The CDC data showed that 27 infants died of unnatural causes during the period 2002–2013,
while the police data recorded 182 unnatural infant deaths during the period 2004–2013, a shorter period but
more unnatural deaths. Thus, the CDC data could have underreported the infant deaths. Keywords: Infant | Unnatural death | Abandonment | China |

Analysis on spatial-temporal features of taxis emissions from big data informed travel patterns: a case of Shanghai, China
تجزیه و تحلیل در مورد ویژگی های زمانی- مکانی حرکت تاکسی ها از الگوهای سفر آگاه داده های بزرگ : یک مورد از شانگهای، چین-2017 Air pollutions from transportation sector have become a serious urban environmental problem, espe
cially in developing countries with expending urbanization. Cleaner technologies advancement and
optimal regulation on the transporting behaviors and related design in infrastructures is critical to
address above issue. To understand the spatial and temporal emissions pattern within transportation lays
the foundation for design on better infrastructures and guidance on low-carbon transportation behav
iors. The feasibility of Global Positioning System (GPS) and emerging big data analysis technique enable
the in-depth analysis on this topic, while to date, applications had been rather few. With this circum
stance, this paper analyzed the taxis energy consumption and emissions and their spatial-temporal
distribution in Shanghai, one of the most famous mega cities in China, applying big data analysis on
GPS data of taxies. Spatial and temporal features of energy consumptions and pollutants emissions were
further mapped with geographical information system (GIS). Results highlighted that, spatially, the
energy consumption and emission presented a distribution of dual-core cyclic structure, in which, two
hubs were identified. One was the city center, the other was Hongqiao transport hub, the activities and
emission was more concentrated in the west par of Huangpu River. Temporally, the highest activity and
emission moment was 9e10AM, the second peak occurred in 7e8PM, which were both the traffic rush
period. The lowest activity/emission moment was 3e4AM. Causal mechanism for such distribution was
further investigated, so as to improve the driving behaviors. Through the exploration of spatial and
temporal emissions distribution of taxis via big dada technique, this paper provided enlightening in
sights to policy makers for better understanding on the travel patterns and related environmental im
plications in Shanghai metropolis, so as to support better planning on infrastructures system, demand
side management and the promotion on low-carbon life styles.

Barriers and benefits to the adoption of a third party certified food safety management system in the food processing sector in Shanghai, China
موانع و منافع برای تطبیق یک سیستم مدیریت ایمنی تصدیق شده سه بخشی در بخش پردازش مواد غذایی در شانگهای، چین-2016 Despite the recent passing of legislation by the National People's Congress of China in 2009, many food businesses in China have yet to implement a third party certified food safety management system (FSMS). While the extent literature identifies a number of internal and external barriers and benefits, the extent to which these impact on the business is thought to be dependent upon how much progress the firm has made on its journey towards quality assurance and the environment within which the firm operates. To test this proposition, the barriers and the benefits accrued from the implementation of a third party certified FSMS were explored by segregating the participating firms into three distinct groups; (i) those that have yet to implement a third party certified FSMS; (ii) those that were in the process of adopting a third party certified FSMS; and (iii) those that were already operating under a third party certified FSMS. Contrary to expectations, in what is a highly competitive market, those firms which were operating under a third party certified FSMS were more likely to question the benefits they had derived than those firms that were either in the process of adoption or had chosen not to adopt a third party certified FSMS. Irrespective of the stage of adoption, the major constraint to the implementation of a third party certified FSMS was the need for the organisation to focus on more immediate issues and the lack of any strategic long-term planning.© 2015 Elsevier Ltd.

Low carbon technology assessment and planning-Case analysis of building sector in Chongming, Shanghai
ارزیابی و برنامه ریزی تکنولوژی کربن های کم مورد تجزیه و تحلیل بخش ساخت و ساز در چونگ مینگ، شانگهای-2016 This paper aims to comparatively analyze the carbon reduction potential of several low carbon tech- nologies by means of different assessment and planning methods for regional development. Seven commonly used building energy saving technologies are evaluated and the priority-setting among them is identified on the example of the building sector in Chongming Island, Shanghai. By applying Decou- pling Theory, the CO2 emission reduction extent under a low carbon scenario and an ideal scenario are estimated for 2030. The required application areas for different technology schemes are calculated using the Technology Combination Planning Method. In order to further find out required application areas for each technology under the least costs, the Goal Programming Method is then applied. Findings of the Technology Combination Planning Method reveal that the combination of energy saving technologies with high GHG emission reduction such as building insulation and geothermal heat pump have obvious effect in helping reducing the required technology application area. Goal Programming provides results for the required application area of each technology, and the minimum emission reduction cost is foundas 2.54 × 108 US dollar under low carbon scenario and 3.50 × 108 US dollar under ideal scenario.© 2015 Elsevier Ltd.
