Detecting Change in Longitudinal Social Networks
Authors: McCulloh Ian , Carley Kathleen M. 
Published: September 2020

Abstract
Changes in observed social networks may signal an underlying change within an organization, and may even predict significant events or behaviors. The breakdown of a team’s effectiveness, the emergence of informal leaders, or the preparation of an attack by a clandestine network may all be associated with changes in the patterns of interactions between group members. The ability to systematically, statistically, effectively and efficiently detect these changes has the potential to enable the anticipation, early warning, and faster response to both positive and negative organizational activities. By applying statistical process control techniques to social networks we can rapidly detect changes in these networks. Herein we describe this methodology and then illustrate it using four data sets, of which the first is the Newcomb fraternity data, the second set of data is collected on a group of mid-career U.S. Army officers in a week long training exercise, the third is the perceived connections among members of al Qaeda based on open source, and the fourth data set is simulated using multi-agent simulation. The results indicate that this approach is able to detect change even with the high levels of uncertainty inherent in these data.
Parallel Arc Diagrams: Visualizing Temporal Interactions
Authors: Hoek Peter 
Published: September 2020

Abstract
This paper introduces a new computer-based visualization method, the parallel arc diagram (PAD), which is capable of uniquely representing 2-mode temporal relationships in a manner that assists in highlighting simple features of the network. The PAD approach relies on a computer’s ability to render link lines adjacent to each other with orderly precision, resulting in features that facilitate preattentive processing of simple network characteristics and providing the ability to discern patterns of interactions over time. PADs supplement existing methods such as node-link diagrams by offering a simple alternative visualization without the computational complexity of graph layout algorithms and the additional issues that animation introduces. This paper subjectively evaluates the PAD approach using low level task taxonomies developed for assessing adjacency matrix and node-link visualization effectiveness. We argue based on those taxonomies that the PAD approach is as effective or in some cases more effective than existing approaches except for tasks requiring the identification of structural groups or middle-man nodes. This paper also demonstrates how the PAD approach can be utilized in a software application. The TIPAD (Temporal Interactive Parallel Arc Diagram) uses character participation in movie scenes as a test-bed for exploring social interactions over time and provides the ability to compare a PAD based visualization with traditional visualizations of the same network.
Explorative Visualization of Citation Patterns in Social Network Research*
Authors: Brandes Ulrik , Pich Christian 
Published: September 2020

Abstract
We propose a visual representation of bibliographic data based on shared references. Our method employs a distance metric that is derived from bibliographic coupling and then subjected to fast approximate multidimensional scaling. Its utility is demonstrated by an explorative analysis of social network publications that, most notably, depicts the genesis of an area now commonly referred to as network science. However, the example also illustrates some common pitfalls in bibliometric analysis.
The study on adsorption behavior of 2,4-DCP in solution by biomass carbon modified with CTAB-KOH

Published: September 2020

Abstract
In this study, rice straw was used to prepare biomass carbon, which was modified with KOH and cetyltrimethylammonium bromide (CTAB) to obtain modified biomass carbon (MBC). The biomass carbon (BC) before and after modification was characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD), thermogravimetric analysis (TGA) and Fourier transform infrared spectroscopy (FT-IR), and the surface morphology, crystal structure and surface group characteristic BC were explored. The specific surface area and micropores of the modified biomass carbon increased significantly, the crystallinity was higher, and the pore structure was more clearly found. The adsorption performance of MBC for 2,4-dichlorophenol (2,4-DCP) was investigated. The results showed that under the best adsorption conditions ((2,4-DCP concentration (200 mg/L), MBC dosage (50 mg), pH (5.5), and loading time (60 min), temperature (room temperature)), the removal rate of 2,4-DCP was up to 42.5%, and adsorption capacity was 85.13 mg/g. The adsorption of 2,4-DCP on MBC materials was better explained by the pseudo-second-order kinetic model and the Langmuir adsorption isotherm model. It was believed that the adsorption of 2,4-DCP by MBC was the monolayer adsorption process on the uniform surface of MBC at high concentration, and there was no interaction between the 2,4-DCP and MBC adsorbate during this process.
Cloud Based Extensible Business Management Suite and Data Predictions
Authors: Dukiya Rajesh , Perumal Kumaresan 
Published: September 2020

Introduction:
The present research work was carried out using an enhanced market prediction
algorithm in the cloud-based business, handing out the CRM system. The approach that is
being predicted will handle and forecast the business with a higher degree of precision and constancy,
the outcome solution of which is found to be compatible with any organization.

Methods:
The CRM framework was proposed in order to overcome the lack of multi-module integration
and functionalities. The developed application is a complete tool for the purpose of managing
the business over cloud. The business owner can host this application on any user interface PHP- and
MySQL-enabled server. An optimized regression model was developed to predict the future of business
and relationship with the customer. For the experimental test, a sample dataset was collected
from the UCI machine learning repository.

Results:
The proposed prediction algorithm is an extension of the time series–based forecasting
model. The projected system is tested with the income and expense cluster data of one year that were
projected for analysis and the result shows better accuracy and constancy than the traditional opportunity
creation driven model.

Conclusion:
It has been observed that the proposed Cloud-Based CRM Framework supports the
organizations to achieve business predictions and maintain healthy relations with their clients and has
worked best for the companies that have to maintain customer end relations. In addition, the customized
CRM tool helps business managers and entrepreneurs to define innovative business strategies.
The CRM application influences customer satisfaction on a large scale and is dominant for the supply
chain system. Overall, the business model indicates that corporate organizations could grab business
insights in a cost-efficient way with upcoming forecasting of sales.

Discussion:
Customer Relationship Management (CRM) is a technology used by the corporate sector
to manage potential customers and their experiences in the view of the seller to consumer through
purchase and post-purchase. In this era of advanced information technology, the sales departments of
multi-product and service-end businesses are struggling hard in order to attain the signal view of the
business. The key criterion for business-boosting decisions includes a single dashboard interface with
a description of relevant information. The biggest challenge for businesses with umbrella views is to
combine the data from various places and obtain market forecasts from the description. The deficiency
in data collection and group management causes market loss or a lack of consumer interest in the
product.

The Impact of Improper Body Posture on Office Workers' Health
Authors: Al-Nakhli Hani H. , Bakheet Hussein G. 
Published: September 2020

Recent data has shown increasing rates of musculoskeletal disorders among the working community. These health-related complications are considered to be amongst the leading causes of disability, and limitation of motion within modern office workers. Many of these disorders are commonly caused by improperly accommodated workplaces. The importance of this study surfaces around the challenges that will be faced during the implementation of Saudi vision's 2030; if this topic is not addressed adequately.
The study aims to detect and prevent office related injuries by investigating their associations with improper workstation ergonomics. This was conducted within the framework of studying the current situation of office ergonomics with focus on sitting postures. Correlations between workers' musculoskeletal pains, and their habits were evaluated.
For collecting the necessary data, a thirty-item questionnaire was distributed to more than one thousand randomly selected workers within Saudi Arabia. This questionnaire was developed to better study the personal demographics, medical information, muscular pain, physical therapy history, workstation ergonomics, and sitting practices.
After filtering and analyzing the collected data, the results of the survey indicated that 78% of the total participants had experienced some sort of musculoskeletal pains, from which 84% of them stated that their sitting postures are awkward, during their working hours. Also, from the total number of musculoskeletal pain sufferers, approximately 32% visited a physical therapy clinic seeking relief for their pains. However, only 39% of them benefitted from the physical therapy interventions, whereas 61% did not. From the individuals whom did not respond to physical therapy, 80% of them identified that they were equipped with ergonomically inconvenient workstations or they were not aware of the correct way to occupy their workstations. To a greater extent, 74% of the total number of participants were supplied with ergonomically inconvenient workstations, which suggests that the employment of anthropometry and workstation ergonomics is not up to standards in Saudi Arabia, causing an extensive impact in escalating muscular pain.
In conclusion, raising the awareness of the population regarding the importance of workplace ergonomics is critical; after highlighting the risks of awkward sitting postures. It is worth mentioning that the appropriate employment of office ergonomics requires the cooperation of both; employees and employers. Only by this alliance, ergonomics will contribute in increasing productivity, and decreasing time loss leading to the maintenance of healthy individuals.

Published: September 2020

This exploratory study critically analyzes instructor perceptions of leaving video feedback and its impact on workload. Using qualitative and quantitative data, it discusses instructor experiences in adding video feedback to written notes in online courses. Specifically, this study asks if instructors will feel more "connected" in video feedback courses, if instructors will report increased workloads, and if they see an improvement in their performance evaluations in video feedback courses. The results reveal that video feedback requires more time than written feedback (i.e., non-video feedback), generates varied instructor experiences concerning social presence, and has little to no impact on instructor performance evaluations. The article concludes that more research is needed to fully understand the instructor experience when using videos, especially in environments where part-time, adjunct instruction is the norm.

Abstract- Online learning has been adapted throughout educational institution recently whereas adoption become inevitably especially during pandemic. Various methods have been adopted by educators with less experience in conducting online learning, thus it is unsurprising that its implementation seems to be a trial and error and has been criticized by various parties. In addition, educators are actually still unfamiliar with various technologies that are widely used in various learning methods. This situation become an obstacle in the application of learning methods since there are too many learning burdens that must be overcome by educators, namely mastery of a variety of methods. and various technological variations without the support of data about the most optimal methods and technologies to use. This study aims to provide an overview of the measurement of the effective usage of technology in various online learning methods associated with the ultimate goal of learning as an important insight for teaching staff in selecting technology and method to be mastered.

No difference in perinatal mortality between home and facility delivery in rural Tanzania: a prospective community-based study
Authors: Konje Eveline T , Magoma Moke T , Hatfield Jennifer , Kuhn Susan , Sauve Reginald S , Dewey Deborah 
Published: September 2020

Background Facility-based delivery with skilled birth attendants in an enabling environment is recommended for life-saving and for improving maternal and newborn health outcomes. Inconsistent results exist regarding the protective effects of facility delivery on maternal and perinatal mortality in developing countries. The primary objective of this study was to investigate the association between place of delivery and maternal and perinatal mortality. A secondary objective was to examine the association between place of delivery and maternal complications during pregnancy, labor and delivery, and 48 hours postpartum. # Methods This community-based prospective study recruited a cohort of 1719 women in their third trimester of pregnancy through a door-to-door survey in randomly selected wards in rural Geita Northwest Tanzania between September 2016 and December 2017. A total of 1385 eligible mother-infant pairs were followed to seven days post-delivery. Results Half of the women delivered at a health facility (52.23%). A limited number of maternal deaths (n=7) were observed; 3 of these occurred at health facilities. No association was found between place of delivery and perinatal mortality (adjusted odds ratio, aOR=1.60, 95% confidence interval, CI=0.65-3.80). The prevalence of maternal complications during pregnancy, labor and delivery, and 48 hours postpartum were 6.14%, 8.74%, and 12.56%, respectively. A higher proportion of women who delivered at health facilities reported complications during labor and delivery (13.26% vs 3.78%) and 48 hours postnatally (14.78% vs 10.14%) than women who delivered at home. Conclusions Health facility delivery was not associated with reduced perinatal mortality. A higher proportion of women who delivered at health facilities reported complications during labour and delivery. Controlling for maternal complications attenuated the association between place of delivery and perinatal mortality. Many health facilities in rural Geita Tanzania remain ill-equipped to deal with unpredictable complications during childbirth. Improving staff training, access to essential drugs and equipment, and quality care could reduce perinatal mortality.
Performance Evaluation of Scalar Multiplication in Elliptic Curve Cryptography Implementation using Different Multipliers Over Binary Field GF (2233)
Authors: Abdul-Hadi Alaa Mohammed , Saif-aldeen Yousraa abdul-sahib , Tawfeeq Firas Ghanim 
Published: September 2020

This paper presents a point multiplication processor over the binary field GF (2233) with internal registers integrated within the point-addition architecture to enhance the Performance Index (PI) of scalar multiplication. The proposed design uses one of two types of finite field multipliers, either the Montgomery multiplier or the interleaved multiplier supported by the additional layer of internal registers. Lopez Dahab coordinates are used for the computation of point multiplication on Koblitz Curve (K-233bit). In contrast, the metric used for comparison of the implementations of the design on different types of FPGA platforms is the Performance Index.
The first approach attains a performance index of approximately 0.217610202 when its realization is over Virtex-6 (6vlx130tff1156-3). It uses an interleaved multiplier with 3077 register slices, 4064 lookup tables (LUTs), 2837 flip-flops (FFs) at a maximum frequency of 221.6Mhz. This makes it more suitable for high-frequency applications. The second approach, which uses the Montgomery multiplier, produces a PI of approximately 0.2228157 when its implementation is on Virtex-4 (6vlx130tff1156-3). This approach utilizes 3543 slices, 2985 LUTs, 3691 FFs at a maximum frequency of 190.47MHz. Thus, it is found that the implementation of the second approach on Virtex-4 is more suitable for applications with a low frequency of about 86.4Mhz and a total number of slices of about 12305.
