Application of ANN and Genetic Algorithm for Evaluation the Optimum Location of Arresters on Power Networks due to the Switching Overvoltages
Authors: Reza Shariatinasab  , Behrooz Vahidi  , Seyed Hossein Hosseinian  , Akihiro Ametani
Published: August 2022

Switching surges are of primary importance in insulation co-ordination of EHV lines, as well as in designing insulation of apparatuses. The magnitude and shape of the switching overvoltages vary with the system parameters, network configuration and the point-on-wave where the switching operation takes place. This paper presents an artificial neural network (ANN) based approach to estimate the peak value of overvoltages and the global risk of failure generated by switching transients during line energizing or re-energizing in different nodes of a power network. Then a genetic algorithm (GA) based method is developed to find the best position of surge arresters on power networks so as to minimize the global risk of the network.

Double circuit flashovers may cause very severe system disturbances when taking place on some critical double-circuit lines of an electrical network. Line arresters offer an efficient solution to protect these specific lines against double circuit outages due to lightning. This paper will study, on a double-circuit 400-kV line, the protection provided by line arresters against double circuit outages due to lightning. The efficiency of several configurations of line arresters will be compared. For that purpose, the double-circuit lightning flashover rates of the line with and without line arresters will be calculated using a newly developed software which includes a three-dimensional electro-geometric model and is able to take into account the random nature of lightning. This software automatically launches EMTP-RV (restructured version of EMTP) for analyzing fast front overvoltages impressed on line insulation. The energy stressing the line arresters will also be calculated in order to evaluate the risk of failure of the line arresters due to excess energy absorption. Furthermore, the effects of several other parameters such as the tower footing resistances, the lightning withstand voltages of insulator strings as well as the protective levels of line arresters will also be investigated.
Line Surge Arresters Applications On The Multi Circuit Overhead Lines
Authors: S. Sadovic  , T. Sadovic
Published: August 2022

This paper presents application of line surge arresters (LSA) on the different voltage level multi circuit overhead lines. Double circuit shielded compact line with and without distribution circuit on the same tower is analyzed. Distribution circuit has lower insulation level, meaning that almost all flashovers will happen on that circuit. Flashovers on the distribution circuit help to improve lightning performance of the transmission circuits. Flashovers on the distribution circuit diverts fraction of the lightning current along its phase conductors, improving at the same time coupling between distribution and transmission circuits. All software simulations are performed using sigma slp software package. A short description of the modeling for multi circuit flashover rate determination is given. In order to prevent flashovers on the distribution circuit LSA are installed on this circuit only. The improvement in the transmission circuit lightning performance is similar to that obtained without LSA. LSA installed on the distribution circuit are much cheaper than transmission LSA.

Total losses of a power transformer are subdivided in several distinctive parts. The I2R losses are easy to calculate and can be precise to a level of measurement repeatability and tolerances of the guaranteed material properties. The additional losses inside the windings can be calculated almost with the same precision using analytic methods. The third part of the load losses that consists of stray losses is the smallest and the most difficult to estimate. However, stray losses estimation is very important in the design phase of a power transformer. Not only because the guaranteed design parameters have to be satisfied, but also the utmost care has to be taken that local losses density across the power transformer does not exceed levels that are permissible in the long term loading conditions of a transformer. The additional losses estimation process presented in this paper models the additional losses level in a transformer as a unit.
Mercancías defectuosas: los motivos de redhibición relacionados con los «defectos físicos y morales» de las esclavas negras de Lima del siglo XVIII a principios del siglo XIX
Authors: Valle-Peguiron Lilia
Published: August 2022

Los expedientes Autos de Redhibitoria conservados en el Archivo General de la Nación del Perú (AGN) y en el Archivo Arzobispal de Lima (AAL) registran las acciones legales emprendidas por los propietarios de esclavos contra los anteriores dueños por haberles ocultado una enfermedad física o un «defecto moral» del esclavo por el cual habían pagado una considerable suma de dinero. En el marco de estos juicios, una gran parte de los documentos se refieren específicamente a las mujeres esclavas. Este artículo se centra en ellas. Durante el juicio, la enfermedad de la esclava se convierte en el tema central del discurso de los propietarios de las esclavas, los médicos y los cirujanos. La declaración de las esclavas enfermas también está presente en la mayoría de los expedientes.Este artículo identifica las enfermedades consideradas como redhibitorias y analiza los discursos de los actores implicados en el proceso de anulación de la venta. El artículo se inscribe en el enfoque de la historia social pues intenta esbozar un perfil, aunque sea fragmentario, de estas mujeres en estado de servidumbre. De este modo, estas mujeres consideradas «inútiles» porque ya no respondían a la lógica de rentabilidad de sus amos, pasan de la invisibilidad al hecho de existir. Se hacen perceptibles a través de la atención que se presta a sus testimonios.

Aim: Our aim was to investigate the value of serum estradiol (E2) on human chorionic gonadotrophin (hCG) trigger day in predicting pregnancy (ongoing pregnancy with live birth, abortion, iu ex, chemical pregnancy) outcomes and neonatal birth weight.

Material-Methods: This retrospective study consisted of two groups: Group 1: Women who had live birth, labor after 22 gestational week (n= 417). Group 2: Women with clinical pregnancy: intrauterine ex, abortus, biochemical and anembryonic pregnancy (n=260).

Demographic characteristics (maternal and paternal ages, body mass index (BMI), gravidity, abortion, and living child) were recorded. Clinical indications (male factor, diminished ovarian reserve...), duration of ovulation stimulation, day 3 (D3) E2, follicle stimulating hormone and luteinizing hormone levels, antral follicle count, total doses of stimulating agents, progesteron and estradiol levels on trigger day, number of oocytes retrieved, number of mature oocytes, endometrial thickness on trigger and oocyte pick-up day were compared between the two groups.

Binary Logistic Regression, (Backward LR model) was used to determine the factors affecting the risk of not having a live birth.

Results: Totally 677 pregnant women were included in the study. We found increased live birth rate in pregnant whom E2 level was higher on the trigger day. There was a statistically significant relation between E2 level on trigger day and newborn weight in live birth (p=0.005) It was determined that the male factor and age of the women are an important parameter that affect not having a live birth (p
Confirming the Existence of Twin Stars in a NICER Way
Authors: Christian Jan-Erik , Schaffner-Bielich Jürgen
Published: August 2022

We demonstrate that future radius measurements of the NICER mission have the potential to reveal the existence of a strong phase transition in dense neutron star matter by confirming the existence of so-called twin stars, compact star configurations with the same mass but different radii. The latest radius constraints from NICER for the pulsars J0740+6620 as well as J0030+0451 are discussed using relativistic mean field equations of state with varying stiffness, connected with a first-order phase transition to quark matter. We show that twin star solutions are compatible with the new radius constraint but are located at radii below the present constraints from NICER, serving as a smoking gun for a strong phase transition in neutron star matter. This scenario is realized if a strong phase transition takes place in neutron stars of the first branch with masses above 2 M
⊙.

Published: August 2022

We investigate the metal species associated with the Lyα forest in eBOSS quasar spectra. Metal absorption lines are revealed in stacked spectra from cross-correlating the selected Lyα absorbers in the forest and the flux fluctuation field. Up to 13 metal species are identified as being associated with relatively strong Lyα absorbers (those with flux fluctuations − 1.0 < δ
Lyα
< − 0.6 and with a neutral hydrogen column density of ∼ 1015−16 cm−2) over the absorber redshift range of 2 < z
abs < 4. The column densities of these species decrease toward higher redshift and for weaker Lyα absorbers. From modeling the column densities of various species, we find that the column density pattern suggests contributions from multiple gas components, both in the circumgalactic medium (CGM) and the intergalactic medium (IGM). While the low-ionization species (e.g., C ii, Si ii, and Mg ii) can be explained by high-density, cool gas (T ∼ 104 K) from the CGM, the high-ionization species may reside in low-density or high-temperature gas in the IGM. The measurements provide inputs for modeling the metal contamination in the Lyα forest baryon acoustic oscillation measurements. Comparisons with metal absorptions in high-resolution quasar spectra and hydrodynamic galaxy formation simulations can further elucidate the physical conditions of these Lyα absorbers.

The degree to which the thin accretion disks of black hole X-ray binaries are truncated during hard spectral states remains a contentious open question in black hole astrophysics. During its singular observed outburst in 2009–2010, the black hole X-ray binary XTE J1752−223 spent ∼1 month in a long-stable hard spectral state at a luminosity of ∼0.02–0.1 L
Edd. It was observed with 56 RXTE pointings during this period, with simultaneous Swift-XRT daily coverage during the first 10 days of the RXTE observations. While reflection modeling has been extensively explored in the analysis of these data, there is disagreement surrounding the geometry of the accretion disk and corona implied by the reflection features. We reexamine the combined, high signal-to-noise, simultaneous Swift and RXTE observations, and perform extensive reflection modeling with the latest relxill suite of reflection models, including newer high disk density models. We show that reflection modeling requires that the disk be within ∼5 R
ISCO during the hard spectral state, while weaker constraints from the thermal disk emission imply higher truncation (R
in = 6–80 R
ISCO). We also explore more complex coronal continuum models, allowing for two Comptonization components instead of one, and show that the reflection features still require only a mildly truncated disk. Finally we present a full comparison of our results to previous constraints found from analyses of the same data set.
Compressed Sensing Based RFI Mitigation and Restoration for Pulsar Signals
Authors: Shan Hao , Yuan Jianping , Wang Na , Wang Zhen
Published: August 2022

In pulsar signal processing, two primary difficulties are (1) radio-frequency interference (RFI) mitigation and (2) information loss due to preprocessing and mitigation itself. Linear mitigation methods have a difficulty in RFI modeling, and accommodate a limited range of RFI morphologies. Thresholding methods suffer from manual factors and adaptability. There is also a distinct lack of methods dedicated to information loss. In this paper, a novel method “CS-Pulsar” is proposed. It carries out compressed sensing (CS) on time-frequency signals to accomplish RFI mitigation and signal restoration simultaneously. Curvelets allow an optimal sparse representation for multichannel pulsar signals containing the time-of-arrival dispersion relationship. CS-Pulsar mitigation is implemented using a regularized least-squares framework that does not require the statistics of RFI to be known beforehand. CS-Pulsar implements channel restoration, and useful signal contents are retrieved from the measurement error by a morphological component analysis aided by the root-mean-square envelope. These two steps allow CS-Pulsar to provide key signal details for special astrophysical purposes. Experiments of signal restoration for pulsar data from the Nanshan 26 m radio telescope reveal the advantage of CS-Pulsar. The method successfully removes false peaks due to on-pulse RFI in multipeaked pulsar profiles. CS-Pulsar also increases the timing accuracy and signal-to-noise ratio proving its feasibilities and prospects in astrophysical measurements.

We present the multi-epoch monitoring with NuSTAR and XMM-Newton of NGC 1358, a nearby Seyfert 2 galaxy whose properties made it a promising candidate X-ray changing-look active galactic nucleus (AGN), i.e., a source whose column density could transition from its 2017 Compton-thick (having LOS hydrogen column density N
H,LOS > 1024 cm−2) state to a Compton-thin (N
H,LOS < 1024 cm−2) one. The multi-epoch X-ray monitoring confirmed the presence of significant N
H,LOS variability over timescales of weeks to years, and allowed us to confirm the changing-look nature of NGC 1358, which has most recently been observed in a Compton-thin status. Multi-epoch monitoring with NuSTAR and XMM-Newton is demonstrated to be highly effective in simultaneously constraining three otherwise highly degenerate parameters: the torus average column density and covering factor, and the inclination angle between the torus axis and the observer. We find a tentative anticorrelation between column density and luminosity, which can be understood under the framework of chaotic cold accretion clouds driving recursive AGN feedback. The monitoring campaign of NGC 1358 has proven the efficiency of our newly developed method to select candidate N
H,LOS-variable, heavily obscured AGN, which we plan to soon extend to a larger sample to better characterize the properties of the obscuring material surrounding accreting supermassive black holes, as well as to constrain AGN feeding models.
Reconstructing the Disrupted Dwarf Galaxy Gaia-Sausage/Enceladus Using Its Stars and Globular Clusters

Published: August 2022

We combine spectroscopic, photometric, and astrometric information from APOGEE data release 17 and Gaia early data release 3 to perform a self-consistent characterization of Gaia-Sausage/Enceladus (GSE), the remnant of the last major merger experienced by the Milky Way, considering stars and globular clusters (GCs) altogether. Our novel set of chemodynamical criteria to select genuine stars of GSE yields a metallicity distribution function with a median [Fe/H] of −1.22 and 0.23 dex dispersion. Stars from GSE present an excess of [Al/Fe] and [Mg/Mn] (also [Mg/Fe]) in comparison to surviving Milky Way dwarf satellites, which can be explained by differences in star formation efficiencies and timescales between these systems. However, stars from Sequoia, another proposed accreted halo substructure, essentially overlap the GSE footprint in all analyzed chemical-abundance spaces, but present lower metallicities. Among the probable GCs of GSE with APOGEE observations available, we find no evidence for atypical [Fe/H] spreads with the exception of ω Centauri (ωCen). Under the assumption that ωCen is a stripped nuclear star cluster, we estimate the stellar mass of its progenitor to be M
⋆ ≈ 1.3 × 109
M
⊙, well within literature expectations for GSE. This leads us to envision GSE as the best available candidate for the original host galaxy of ωCen. We also take advantage of Gaia's photometry and APOGEE metallicities as priors to determine fundamental parameters for eight high-probability (>70%) GC members of GSE via statistical isochrone fitting. Finally, the newly determined ages and APOGEE [Fe/H] values are utilized to model the age–metallicity relation of GSE.

In this third paper of the series reporting on the reverberation mapping campaign of active galactic nuclei with asymmetric Hβ emission-line profiles, we present results for 15 Palomar–Green quasars using spectra obtained between the end of 2016–2021 May. This campaign combines long time spans with relatively high cadence. For eight objects, both the time lags obtained from the entire light curves and the measurements from individual observing seasons are provided. Reverberation mapping of nine of our targets has been attempted for the first time, while the results for six others can be compared with previous campaigns. We measure the Hβ time lags over periods of years and estimate their black hole masses. The long duration of the campaign enables us to investigate their broad-line region (BLR) geometry and kinematics for different years by using velocity-resolved lags, which demonstrate signatures of diverse BLR geometry and kinematics. The BLR geometry and kinematics of individual objects are discussed. In this sample, the BLR kinematics of Keplerian/virialized motion and inflow is more common than that of outflow.

Published: August 2022

Background: Histoplasmosis is a disease caused by fungus called Histoplasma capsulatum. Several studies reported cases of histoplasmosis that resembled malignancy [3]. . It is a fact that the clinical syndrome of neoplastic disease is not limited to malignancy, so that infectious diseases should be considered in the differential diagnosis. Method: This is descriptive research with consecutive samples. The sample was the patients with lung cancer aged 25-75 years old. The researcher assessed histoplasmic skin test on interdemal administered with fungal protein [5]. After being observed for allergic reaction in 48-72 hours, induration > 5mm shows positive reaction. The Result: this research included 25 samples consisting of 21 men and 4 women. The Result showed 1 person (4%) with positive histoplasmic skin test result containing squamous cell carcinoma and radiological features of solitary pulmonary nodule. There is an insignificant relationship between cancer cell types and the histoplasmic skin test results (p = 0.24). There is an insignificant relationship between histoplamic skin test result and radiological features (p = 0.48). 
The Conclusion: There is one person with positive histoplasmic skin test result with squamous cell carcinoma and radiological features of solitary pulmonary nodule.
Misleading fruits: The non-monophyly of Pseudopiptadenia and Pityrocarpa supports generic re-circumscriptions and a new genus within mimosoid legumes

Published: August 2022

Generic delimitation in Piptadenia and allies (mimosoid legumes) has been in a state of flux, particularly caused by over-reliance on fruit and seed morphology to segregate species out of Piptadenia into the genera Parapiptadenia, Pityrocarpa and Pseudopiptadenia. Although supporting their segregation from Piptadenia, previous phylogenetic analyses suggested that some of these segregated genera are not monophyletic. Here, we test the monophyly of Parapiptadenia, Pityrocarpa and Pseudopiptadenia with dense taxon sampling across these genera, including the type species of each genus. Our analysis recovers Parapitadenia as monophyletic, but places Pseudopiptadenia species in two distinct lineages, one of which includes all three species of Pityrocarpa. Given that the type species of both Pseudopiptadenia and Pityrocarpa are nested in the same clade, we subsume Pseudopiptadenia under the older name Pityrocarpa. The remaining Pseudopiptadenia species are assigned to the new genus Marlimorimia. Alongside high molecular phylogenetic support, recognition of Parapiptadenia, Pityrocarpa and Marlimorimia as distinct genera is also supported by combinations of morphological traits, several of which were previously overlooked.

Background/Aims: Pulmonary toxicities of coronavirus disease 2019 (COVID-19) vaccination are exceedingly rare. However, there are a few reported cases after mRNA vaccination, especially from Asian countries. The purpose of this study was to report the clinical characteristics of patients with COVID-19 vaccine-related pneumonitis (CV-P) and to review cases reported in the literature.Methods: We performed a prospective, observational case series analysis.Results: Eleven patients with a median age of 80 years were enrolled. Ten patients developed CV-P after BNT162b2-mRNA vaccination and one after ChAdOx1 nCoV-19 vaccination. We identified various patterns of CV-P, including transient infiltration, life-threatening acute respiratory distress syndrome, and aggravation of underlying interstitial lung disease. Most patients showed favorable outcomes with good responses to corticosteroid therapy.Conclusions: Identifying the mechanism of CV-P requires further investigation; however, radiological and laboratory findings in our case series support inflammatory dysregulation in the lung parenchyma after vaccination. Clinicians should consider CV-P in patients with atypical lung infiltration, no specific etiologies, and recent COVID-19 vaccination

Published: August 2022

Face recognition is an important biometric in video surveillance. However, the conventional algorithms of face recognition are also susceptible to various conditions. The contribution of this chapter is to explore face recognition by using deep learning, including detecting the location of human faces on the given images at various distances and multiple angles. In the distances, the influence of the distance from the camera to a face and the size of the face in the images is explored. There are 500 images collected from various videos as the input and they are applied to train the proposed models. The accuracy of face recognition from the videos excluding training dataset is at 90.18%. The results indicate that this method is able to recognise human faces with partial occlusion and various distances.

Classroom management relies heavily on the ability to keep track of student attendance. Attendance checks by calling names or handing out a sign-in sheet are time-consuming and vulnerable to fraud, especially the latter. Data science and image processing are the focus of this regarding counting the number of people present at a gathering for various objectives, such as determining a person's duty status, determining a person's physical presence in a classroom, determining a person's security clearance to enter a meeting hall, etc. It takes a lot of time and effort to maintain a database for future use when generating attendance records using the standard technique. With the help of the latest technology, attendance can be entered automatically. It is a frequently used face recognition technique that generates a binary code for each cell and compares it to the reference image. With the use of deep learning, this LBP method has been reworked in order to automate attendance generation.

The relevance of sustainability in contemporary society is on a growing trend owing to the predominance of economic development and environmental conservation plans amidst challenges of climate change. Eco-efficiency is a growing tool to qualify economic and environmental sustainability. In this chapter, the trends of eco-efficiency over the last three decades were evaluated in a bibliometric analysis from publications in the Web of Science database. An analysis of the publications, the journals they were published in, keywords used, and citations among other aspects was done using the VOSviewer software. Findings showed that the eco-efficiency concept was predominantly applied in the environmental sciences and technology fields among others. The growth in the concept was exponential, and the majority of publications were from developed countries. The application of the concept is a roadmap to better resource management and sustainable development.

Although disruptive innovation is a shortcut to increase revenue by technology, it has been applied little in the hotel industry. The purpose of this study is to examine how disruptive innovation has been applied in hotels via adopting a digital tool of linguistic inquiry word count (LIWC) to explore guests' unconscious needs to increase hotel revenue. The study has been based on the Maslow's hierarchy and the McClelland's motivation to examine the relationships between hotel criteria and guests' unconscious needs to increase hotel revenue. The study sample includes 10918 comments from online travel agency websites of hotels in the southeast destinations of the United States from January 2015 to October 2016. Findings from canonical correlation analyses indicate that hotel value and cleanliness would attract guests with a high-power motive whereas hotel service and quality would attract guests with a high affiliation motive. Finally, hotel room and location would attract guests with a high achievement motive. Implications have been discussed.

The concept of sustainable development has been introduced following the Brundtland Commission's report “Our Common Future.” Though significant volume of literature does exist on the various aspects and impacts of the mentioned commission, the actual impact of the commission on the environment for which it was initiated has never been considered by any academicians. The chapter tries to quantify the qualitative aspect of environment through per capita emission of CO2 over the years. It shows that the concerned commission is successful in bringing down the rate of growth of per capita CO2 emissions, but it is yet to be negative. The chapter opines that to restore the resilience of the environment and to make ecology and economy synonymous again, further efforts are needed.

Crisis Communication and Management
Authors: Golt Suzanne Graham
Published: August 2022

This chapter provides suggestions as to what could be included in a crisis communication and management plan. It is strongly encouraged that a professional review the plan and customize it for the specific needs of a school district or business. This chapter will briefly focus on three main topics of crisis communication and management: 1) pre-crisis/preparedness, planning ahead in the event of a crisis with the main goal of preventing loss of life, injury, or damage to property; 2) active crisis/response, what to expect and what will take place after authorities are on the scene; and 3) post-crisis/recovery, debriefing after the crisis to document what occurred and discuss what could have been done differently.
More Than Milling

During crisis events, emergency responders must verify the particulars of an event before sending out warning messages. The gap between an event's occurrence and official notification is often used by those impacted by that event to verify what is happening before taking action. The addition of information communication technologies has had an impact on what we term the verification pause. This pause is the amount of time it takes to verify what has happened before messages are received and before reaction can begin. More than milling about post notification, this understudied period of time is rarely visible for researchers. The present case study contains an analysis of a verification pause between an earthquake event and the actions taken by students in a classroom in a large university in the United States. The students in the classroom felt the earthquake and immediately began to search for verification that what they felt was indeed an earthquake. The authors conclude with a discussion of the utility of case studies and call for more focused analysis of the similarities between cases.
Seismic Risk Communication

Published: August 2022

The chapter presents some aspects of the seismic risk communication within a systemic disaster management system (SDMS) model. Information and communication technology (ICT) plays a key part in managing natural disasters. An example of seismic risk preparedness for the case of preparatory schools in Mexico City has been used to illustrate this feature of the model. Some conclusions are (1) the model has shown the potentiality to the understanding of the flow of information amongst they key subsystems of the model. It can also be used to any natural hazard management. Regarding the case study, (2) 52% of the participants are not sure whether the key decision makers are concern regarding the level of preparedness of the students for the case of earthquakes; (3) 44.1% of the students considered the best way to learn more on earthquakes was through “civil protection” courses; (d) finally, the actions that the decision makers could take are the implementation of seismic risk courses that should be run by civil protection and to promote the culture of preparedness on seismic risk.
Health Risk Communication and Media
Authors: Kumbasar Banu
Published: August 2022

Risk communication is a concept defined by many organizations like World Health Organization (WHO) and Centers for Disease Control and Prevention (CDC). Effective risk communication is a complex process. It is an interactive process of exchange of information and opinion among individuals, groups, and institutions. Risk communication is part of the risk management process, with the primary aims to promote awareness and understanding of risks. In the risk management process, risk communication is at the center. There are a number of approaches to the process of risk communication and its components, including how messages are sent and received. The management of public health outbreaks has always included a specific communication component in the form of warnings, risk messages, evacuation notifications, messages regarding self-efficacy, information regarding symptoms, and medical treatment, among many others. Media can play a significant role for raising awareness of the health issues. But the difficulty is to find the right channel of communication for the target audience.
Evaluation of Research Trends in Social Media Crisis Communication
Authors: Nwogwugwu Daniel Ikesinachi
Published: August 2022

An organization's survival during a crisis often depends on its speed of response. The introduction of social media into crisis communication discourse has meant that organizations must revisit their crisis communication strategies. This chapter explores a content analysis of the integration of social media platforms into crisis communication based on a comprehensive review of eight purposively selected crisis studies conducted globally. Findings revealed that Facebook and Twitter are increasingly employed as platforms for crisis communication. It was also discovered that responding to crises promptly, and engaging with the publics before, during, and after crises are crucial to managing organizational reputation. Social media platforms are also capable of spreading mis(information) about crises. Thus, organizations are advised to fully integrate and adopt social media into their crisis communication plans. This chapter extends our understanding of how social media platforms contribute to crisis communication discourse.

It is important to know which PR strategies engage stakeholders because it is critical for the survival of a company that it maintains healthy relationships with all entities. A case study was conducted to explore what ruins a company's image and what role a PR department plays in rejuvenating it. To gain valuable insights into this topic, interviews were conducted with fourteen PR professionals including people who are working in the mentioned case studies places and organizations that faced some crisis in this chapter. Results suggest PR plays a critical role during crisis management; through PR teams, organizations can turn adverse situations to their favor and reconstruct reputations that would otherwise be tarnished.
Twitter-Based Disaster Response Using Recurrent Nets
Authors: Lamsal Rabindra , Kumar T. V. Vijay
Published: August 2022

Twitter has become the major source of data for the research community working on the social computing domain. The microblogging site receives millions of tweets every day on its platform. Earlier studies have shown that during any disaster, the frequency of tweets specific to an event grows exponentially, and these tweets, if monitored, processed, and analyzed, can contain actionable information relating to the event. However, during disasters, the number of tweets can be in the hundreds of thousands thereby necessitating the design of a semi-automated artificial intelligence-based system that can extract actionable information based on which steps can be taken for effective disaster response. This paper proposes a Twitter-based disaster response system that uses recurrent nets for training a classifier on a disaster specific tweets dataset. The proposed system would enable timely dissemination of information to various stakeholders so that timely response and proactive measures can be taken in order to reduce the severe consequences of disasters. Experimental results show that the recurrent nets outperform the traditional machine learning algorithms with regard to accuracy in classifying disaster-specific tweets.
