The Role of Flexibility in Enhancing Operational Performance Through Sustainability Practices. (c2021)

Flexibility and Sustainability are two philosophies that the original equipment manufacturers (OEMs) invested heavily in since the 21st century. The impact of these two philosophies exceeds operations and extends to customers, communities, employees, and innovation. This thesis identified the lack of empirical research investigating the relationship between flexibility and sustainability and their combined interactions with operational performance metrics. Very few studies investigated this relationship in limited depth and breadth. Therefore, this thesis aims to investigate the interaction between flexibility, sustainability, and their impact on operational performance in the United States (US) and European (EU) OEMs. Based on the contingency theory and resource-based view theory, a conceptual model linking flexibility, sustainability, and operational performance was developed and empirically tested. After reviewing previous literature and consulting academicians and practitioners experienced in the topic, a survey was developed. The survey was conducted with a total of 140 respondents. The respondents are managers at OEMs facilities in Europe and the US. The results indicated a significant and positive relationship between flexibility and operational performance, flexibility and sustainability, and sustainability and operational performance. The results also revealed that sustainability mediates the relationship between flexibility and operational performance. This study can help managers know what flexibility and sustainability practices optimize operational performance.
A new hybrid of the genus Origanum L. (Lamiaceae): Origanum × symes Carlström

Background and Aims: Origanum × symes was described as a new species by Carlström in 1984 on the Aegean Island of Symi (Dodecanese, Greece). In this work, a taxonomic re-evaluation of O. symes is proposed in light of new findings. Methods: New specimens belonging to Origanum symes from the island of Symi were collected by the first author in 2017. These specimens were carefully examined and compared with the type specimen of O. symes . Also, the new Origanum symes specimen was compared morphologically with O. calcaratum and O. onites , which are possible parents, and their calyces were drawn. Results: The new hybrid was morphologically compared with its putative parents Origanum calcaratum and O. onites (see Table 1). Its diagnostic features, description, figures, and distribution map were provided. Conclusion: It has been determined that O. symes has intermediate characteristics between its two parents in terms of fea- tures such as leaves, calyx, and corolla. These determinations led us to hypothesize that O. symes is a hybrid. As a result, it was concluded that O. symes was a hybrid between O. calcaratum and O. onites , and was re-arranged as Origanum × symes Carlström.
Understanding the Role of the Internet in the Digital Age: A Multichannel, Multistudy Examination

The Internet has come to occupy a central place in modern everyday life and influences consumer behavior profoundly. This thesis takes a close look at the importance of distribution and customer acquisition channels on the Internet in three different empirical projects. Project I shows positive effects of customer-initiated channel migration from direct to indirect channels and offline to Internet channels on the customer relationship. The results of Project II demonstrate a U-shaped effect of advertiser competition on consumer click-through and conversion behavior on search engines. In addition, the results of Project II show that consumers do not reduce cognitive efforts by applying simple decision heuristics with increased advertiser competition and thus choice overload. Project III illustrates, investigating order effects and double exposure on search engine result pages, the impact of organic and paid search results and the effect of their interdependency for consumer click-through behavior on search engine result pages.
The indignities of working with racialization: physical, emotional and familial tolls of experiencing workplace racism

ABSTRACT Canada is often viewed as an oasis of multicultural inclusion where racially diverse groups could freely enjoy life in all its forms. Focusing on a group of twenty-five racialized participants working for the public sector in British Columbia (BC), this qualitative study illustrates that workplace racism is alive and prevalent in Canada. Moreover, it aims to demonstrate that this form of racism impacts not only racialized individuals who are targeted, physically and emotionally, but also their families. After presenting an outline of what constitutes racism and racialization, the article will detail and discuss findings with respect to physical, psycho-emotional and familial tolls that experiencing racial discrimination at work had exacted on racialized participants. The paper will then conclude that considering the higher expectations from public servants for not only modeling equity behavior but also upholding the rule of law, opportunities exist to more seriously address systemic racist violence against racialized workers in public sector employment contexts.
The Physical Activity Level Of Medical Students Does Not Correlate With Their Sleep Quality And Excessive Daytime Sleepiness (EDS)

One of the main causes of non-communicable diseases is an unhealthy lifestyle. One of the examples is a lack of physical activity. Physical activity is important for good sleep quality and prevents excessive daytime sleepiness (EDS), which can interfere with productivity. This observational analysis with a cross-sectional study approach aims to determine the relationship between the level of physical activity and sleep quality and excessive daytime sleepiness in medical students at the faculty of medicine, Universitas Brawijaya. 444 respondents were included in this study. The level of physical activity was measured using the short version of the International Physical Activity Questionnaire, sleep quality was measured with the Pittsburg Sleep Quality Index (PSQI), and EDS was measured with the Epworth Sleepiness Scale (ESS). The results showed that 230 (51.8%) respondents had moderate levels of physical activity, 286 students (64.4%) had poor sleep quality, and 291 students (65.5%) did not experience EDS. The results of the Chi-square correlation test showed p-values of 0.508 and 0.470 for the relationship between physical activity, sleep quality, and EDS, respectively. It can be concluded that there is no significant relationship between the level of physical activity and sleep quality, and EDS. Further study with many other factors needs to be done to determine the contributing factors to sleep quality and EDS.
iSwift: Fast and Accurate Impact Identification for Large-scale CDNs

One key challenge to maintain a large-scale Content Delivery Network (CDN) is to minimize the service downtime when severe system problems happen (e.g., hardware failures). In this case, a critical step is to quickly and accurately identify the range of users with performance degradation, termed impact identification. Successful impact identification not only helps identify impacted users but also provides meaningful information for troubleshooting. However, current practice of impact identification usually takes network engineers several hours to manually identify impacted users, which may lead to a huge business loss. The main challenges for automatic impact identification in large CDNs include the inaccuracy of underlying anomaly detection, huge search space of impact identification and severe long-tail distribution of user traffic. In this paper we propose iSwift, a system that is specifically designed for impact identification in large-scale CDNs in order to address aforementioned challenges. We evaluate the performance of iSwift on semi-synthetic datasets and the results show that iSwift can achieve a F1-score greater than 0.85 within ten seconds, which significantly outperforms state-of-the-art solutions. Furthermore, iSwift has been deployed in a production CDN around one year as a pilot project and demonstrated its online performance confirmed by the network operators.
A Novel Topography Retrieval Algorithm Based on Single-Pass Polarimetric SAR Data and Terrain Dependent Error Analysis

Polarimetric synthetic aperture radar (PolSAR) data provide an alternative way for topography retrieval, especially when limited PolSAR data are available. This article proposes a novel topography retrieval algorithm based on the Lambertian backscatter model that further improves the vertical precision of digital elevation model (DEM) generation and requires only one flight. The key idea of the proposed algorithm is to avoid data fluctuations caused by the ratio of the azimuth slope angle to the polarimetric orientation angle (POA). The previous research has confirmed the feasibility of generating a DEM based on single-pass PolSAR data, but its effect on the quality of reference DEM has not been well-explained. To analyze this effect, a large number of experiments on DEM with different resolutions are conducted. In addition, an in-depth analysis of non-linear and terrain-dependent errors is performed. The L-band PolSAR data of NASA/JPL TOPSAR and ALOS-2 PALSAR-2 and interferometric SAR (InSAR) DEM data are used to verify the proposed algorithm. The experimental results show that PolSAR data can be used as an additional reliable information source for DEM fusion under certain conditions to improve the quality of public DEM.

Mn3O4 Catalysts for Advanced Oxidation of Phenolic Contaminants in Aqueous Solutions

Water-soluble organic pollutants, such as phenolic compounds, have been exposed to environments globally. They have a significant impact on groundwater and surface water quality. In this work, different Mn3O4 catalysts were prepared for metal oxide activation of peroxymonosulfate (PMS) to remove the phenolic compound from the water environment. The as-prepared catalysts were characterized using thermogravimetric-differential thermal analysis (TG-DTA), powder X-ray diffraction (XRD), scanning electron microscopy (SEM), and Brunauer-Emmett-Teller (BET) surface area analysis. Furthermore, the effect of temperature and reusability of the as-prepared Mn3O4 catalysts is also investigated. The Mn3O4 nanoparticles (NPs) catalyst reveals an excellent performance for activating PMS to remove phenol compounds. Mn3O4 NPs exhibits 96.057% efficiency in removing 25 ppm within 60 min. The kinetic analysis shows that Mn3O4 NPs fitted into pseudo-first order kinetic model and exhibited relatively low energy activation of 42.6 kJ/mol. The reusability test of Mn3O4 NPs displays exceptional stability with 84.29% efficiency after three-sequential cycles. The as-prepared Mn3O4 NPs is proven suitable for phenolic remediation in aqueous solutions.

Short-term temporal and spatial analysis for post-fire vegetation regrowth characterization and mapping in a Mediterranean ecosystem using optical and SAR image time-series

Abstract In the present study, the temporal and spatial dynamics of the post-fire recovery of different Mediterranean vegetation types during the three years after the fire event were analyzed, according to different fire severity categories, integrating the use of Synthetic Aperture Satellite Radar (SAR) (Sentinel-1) and optical (Sentinel-2) image time series. The results showed that Mediterranean forest species and shrub/herbaceous species are adapted to fire, with high efficiency in restoring the vegetation cover. Differently, the ecological vulnerability of non-native eucalyptus plantations was found in a lower recovery trend during the observation period. The use of optical short-wave infrared (SWIR) and SAR C-band-based data revealed that some ecological characteristics, such as the woody biomass and structure, recovered at slower rates, comparing to those suggested by using near-infrared (NIR) and red-edge data. An optimized burn recovery ratio (BRR) was proposed to estimate and map the spatial distribution of the degree of vegetation recovery.

Rainwater Isotopic Composition in the Ecuadorian Andes and Amazon Reflects Cross-Equatorial Flow Seasonality

The variability of the rainfall stable isotopic values (δ2Hp, δ18Op) in the Ecuadorian Amazon to the Andes presents a marked local “altitude” effect. At the same time, this complex orography creates diverse precipitation regimes (unimodal, bimodal, and three-modal) that make it difficult to establish a relationship with the local amount. Nevertheless, stations along these regions show a similar intra-annual isotopic variability, with lower values during MAM and ON. In contrast, higher values are found during DJF and JAS in a w-shaped pattern, suggesting a common regional controller. A monthly δ2Hp and δ18Op collection campaign was established in Central Ecuador (n = 30) to complement stations biased towards the northern and southern parts. Based on back trajectory analysis, the results demonstrated that moisture arrives from two primary sources: the Tropical North Atlantic (DJFM) and the Amazon Basin (JAS). Nevertheless, their convergence (AMJ and ON) is the crucial factor modulating the lowest isotopic values. Precisely, this convergence is stronger at the V-Index region (5° S–5° N, 65°–75° W), where the wind seasonality and reversal at low levels are enhanced, allowing the inter-hemispheric moisture flux transport (cross-equatorial flow). We propose that the amount of rainfall located at the V-Index region is a more robust approach for explaining the δ2Hp and δ18Op variability rather than the local amount.
The COVID‐19 scamdemic: A survey of phishing attacks and their countermeasures during COVID‐19

Abstract The COVID‐19 pandemic coincided with an equally‐threatening scamdemic: a global epidemic of scams and frauds. The unprecedented cybersecurity concerns emerged during the pandemic sparked a torrent of research to investigate cyber‐attacks and to propose solutions and countermeasures. Within the scamdemic, phishing was by far the most frequent type of attack. This survey paper reviews, summarises, compares and critically discusses 54 scientific studies and many reports by governmental bodies, security firms and the grey literature that investigated phishing attacks during COVID‐19, or that proposed countermeasures against them. Our analysis identifies the main characteristics of the attacks and the main scientific trends for defending against them, thus highlighting current scientific challenges and promising avenues for future research and experimentation.
Consistency assessment of multi-date PlanetScope imagery for seagrass percent cover mapping in different seagrass meadows

Abstract Seagrass percent cover is a crucial and influential component of the biophysical characteristics of seagrass beds and is a key parameter for monitoring seagrass conditions. Therefore, the availability of seagrass percent cover maps greatly assists in sustainable coastal ecosystem management. This research aimed to assess the consistency of PlanetScope imagery for seagrass percent cover mapping using two study areas, namely Parang Island and Labuan Bajo, Indonesia. Assessing the consistency of the PlanetScope imagery performance in seagrass percent cover mapping helps understand the effects of variations in the image quality on its performance in monitoring changes in seagrass cover. Percent cover maps were derived using object-based image analysis (image segmentation and random forest) and pixel-based random forest algorithm. Accuracy assessment and consistency analysis were conducted on the basis of the following three approaches: overall accuracy consistency, agreement percentage and consistent pixel locations. Results show that PlanetScope images can fairly consistently map seagrass percent cover for a specific area across different dates. However, these images produced different levels of accuracy when used for mapping in seagrass meadows with various characteristics and benthic cover complexities. The mapping accuracy (OA–overall accuracy) and consistency (AP–agreement percentage) in patchy seagrass meadows (Parang Island, mean OA 18.4%–38.6%, AP 44.1%–70.3%) are different from those in continuous seagrass meadows (Labuan Bajo, OA 43.0%–56.2%, and AP 41.8%–55.8%). Moreover, PlanetScope images are consistent when used for mapping seagrasses with low and high percent covers but strive to obtain good consistency for medium percent cover due to the combination of seagrass and non-seagrass in a pixel. Furthermore, images with relatively similar image acquisition conditions (i.e., winds, aerosol optical depth, signal-to-noise ratio, and sunglint intensity) produce better consistency. The OA is related to the image acquisition conditions, whilst the AP is related to variation in these conditions. Nevertheless, PlanetScope is still the best high spatial resolution image that provides daily acquisition and is highly beneficial for various applications in tropical areas with persistent cloud coverage.
Perinatal Outcomes and Related Risk Factors of Single vs Twin Pregnancy Complicated by Gestational Diabetes Mellitus: Meta-Analysis

Objective Perinatal outcomes and related risk factors of single vs twin pregnancy complicated with gestational diabetes mellitus (GDM) were clarified, providing evidence for developing preventive measures. Methods The Chinese National Knowledge Infrastructure (CNKI), China Biology Medicine (CBM), CQVIP, Wanfang, and PubMed databases were searched for published research on the perinatal outcomes and risk factors of single and twin pregnancy complicated by GDM from 2000 to 2021. The quality of the included literature was evaluated according to the Newcastle-Ottawa Scale (NOS). Meta-analysis of the included literature was conducted using RevMan5.3 software. Results Relative to a single pregnancy group, infertility, gestational weight gain, and family history of diabetes presented statistical significance in the twin pregnancy group (P < 0.05); gestational age at delivery, cesarean section, preterm birth < 37 weeks, and preeclampsia presented statistical significance in the twin pregnancy group (P < 0.05); and neonatal birth weight, small for gestational age (SGA), neonatal asphyxia, neonatal hypoglycemia, neonatal respiratory distress syndrome (NRDS), neonatal hyperbilirubinemia, and neonatal death presented statistical significance in the twin pregnancy group (P < 0.05). Conclusion Infertility, prenatal weight gain, and diabetes in the family are all risk factors for postpartum impaired glucose metabolism in pregnant women with GDM who are carrying twins. The gestational age at delivery, cesarean section, preterm birth < 37 weeks, and preeclampsia of twin pregnant women with diabetes will affect the perinatal status of twin pregnant women. Neonatal birth weight, SGA, neonatal asphyxia, neonatal hypoglycemia, NRDS, neonatal hyperbilirubinemia, neonatal death, etc. should be paid special attention in the perinatal process.
