Diagnose the viability of separation of power in Egypt: a cybernetics perspective
Authors: Zeini Nahed T. 
Published: December 2021

PurposeThe aim of this study is to diagnose the Egyptian political system from the perspective of the viable system model (VSM). That in turn gives us significant insights on how to improve the distribution and control of power in Egypt to warrant greater autonomy and representativeness in the branches of government.Design/methodology/approachThe proposed diagnostic framework in this study was accomplished by applying the principles and aspects of Stafford Beer's VSM to the three state powers of Egypt: the executive, legislative and judiciary. In addition, it adopts the guidelines for applying the VSM described by both Stafford Beer and José Pérez Ríos.FindingsThe presented framework in this study shows a comprehensive explanation of the essential functions and their distribution among the entities of the Egyptian political system. In addition to that, the findings give us insights about the need for greater autonomy and self-organization among the political system's entities. Greater communication, consensus, cooperation and coordination is needed to achieve balance, regulate the interactions between them and to monitor each other without intervention. This, in turn, would ensure greater representation of citizen demands and expectations, and protect and guarantee their rights and freedoms.Originality/valueThe modeling of the Egyptian political system from a VSM perspective suggests the necessity of reform of the political system by a clear division of functions and tasks within the operational entities and subentities, decentralization of power structures and utilization of the decision marketing mechanism to reach public acceptance. The application of the VSM, for the sake of diagnosing and designing the viability of separation of power, can be considered as highly original.

Authors: Tinega Joseph Nyamoko , Warui Charles Mwaura 
Published: December 2021

PurposeThe aim of this study is to examine the effect of carbonization on the surface and its influence on heavy metal removal by water hyacinth based carbon.Design/methodology/approachDried water hyacinth stem was used as precursor to prepare carbon based adsorbent by pyrolysis method. The adsorbent proximate (ash, volatile matter and fixed carbon) and elemental (carbon hydrogen nitrogen sulfur) composition, surface area, pore size distribution, surface chemistry was examined and compared.FindingsThe results demonstrated that through carbonization in comparison to dried water hyacinth stem, it increased the surface area (from 58.46 to 328.9 m2/g), pore volume (from 0.01 to 0.07 cc/g), pore size (from 1.44 to 7.557 Å) thus enhancing heavy metal adsorption. The metal adsorption capacity of Cd, Pb and Zn was measured and analyzed through induced coupled plasma-mass spectrometer. At metal concentration of 0.1 mg/l adsorption rate for Cd, Pb and Zn was 99% due to increased large surface area, coupled with large pore size and volume. Furthermore, the adsorbent surface hydroxyl group (OH−) enhanced adsorption of positively charged metal ions through electrostatic forces.Practical implicationsIt is presumed that not only adsorption with synthetic wastewater but real wastewater samples should be examined to ascertain the viability of adsorbent for commercial application.Originality/valueThere are little or scanty data on the effects of carbonization on water hyacinth stem based carbon and subsequent effects on heavy metal removal in effluents.

Published: December 2021

PurposeThis study aims to evaluate the effect of pH on the reinforced concrete steel protection for rebars coated with paint formulations containing talc and free from it. As the presence of talc in paints can offer high pH which cordially affects the protection behavior of the coated rebars. Additionally, this study includes evaluating the durability of concrete mixes in presence of some replacements of ordinary cement such as meta-kaolin (MK) and ground granulated blast furnace slag (GGBFS).Design/methodology/approachTwo paint formulations were prepared containing the same ingredients except that (P1) is free from talc and (P2) contains talc. The anticorrosive behavior of painted steel in the blended concrete mixes containing MK and GGBFS was studied by using different electrochemical techniques in chloride solution. The concrete durability was evaluated by the means of compressive and bond strength beside chloride permeability. Different concrete mixes containing mineral groups or pozzolanic materials were prepared by replacing (10, and 30%) GGBFS and (5, 10 and 15%) MK as binary from cement CEM I with (w/b) 0.45 with superplasticizer ratio (SP) 2% of the binderFindingsIt was found that the presence of talc, in spite of its ability to offer high pH, has affected positively the corrosion behavior of reinforced concrete steel by forming a complex with concrete even if it is present in paint formulation and not free in the medium.Originality/valueThe results revealed that concrete blended with (30% GGBFS and 10% MK) with coated rebars with P2 containing talc showed the highest corrosion protection performance in addition to modified permeability and compression resistance.

This study answers on how MO and capabilities can enhance the performance of a firm. The following research points have been looked into: (1) business development in uncertain times, (2) strategies that complement both business development and competitive advantage at the same time and (3) how proactive MO helps the business organization to improve performance and attain category leadership in the desired therapeutic segment.Design/methodology/approachThis article is based on an intensive case study that provides a thorough description, interpretation and understanding of the case. To accomplish the given goals, a public sector firm was carefully chosen and data were gathered through interviews with managers from different levels of the case company.FindingsResults of this study explain that the MO concept is highly effective in building the marketing capabilities and sustaining the performance. The study offers business development strategies for the businesses where product differentiation is low and price ceiling is practiced on a certain category of products. MO when combined with marketing capabilities gives the organization a competitive advantage which ultimately enhances the firm performance.Originality/valueThe manuscript is based on a case study representing niche and mid-sized Indian pharmaceutical company, “Indian Immunologicals Limited” (IIL, a public sector firm), that adopted MO along with competitive business strategies in highly competitive, regulated and price control therapeutic category, anti-rabies vaccine. The company with a judicious mix of business strategies, operational excellence and MO not only enhanced productivity but also market share and created new business units for future.
Predicting bitcoin price movements using sentiment analysis: a machine learning approach
Authors: Gurrib Ikhlaas , Kamalov Firuz 
Published: December 2021

Purpose
Cryptocurrencies such as Bitcoin (BTC) attracted a lot of attention in recent months due to their unprecedented price fluctuations. This paper aims to propose a new method for predicting the direction of BTC price using linear discriminant analysis (LDA) together with sentiment analysis.

Design/methodology/approach
Concretely, the authors train an LDA-based classifier that uses the current BTC price information and BTC news announcements headlines to forecast the next-day direction of BTC prices. The authors compare the results with a Support Vector Machine (SVM) model and random guess approach. The use of BTC price information and news announcements related to crypto enables us to value the importance of these different sources and types of information.

Findings
Relative to the LDA results, the SVM model was more accurate in predicting BTC next day’s price movement. All models yielded better forecasts of an increase in tomorrow’s BTC price compared to forecasting a decrease in the crypto price. The inclusion of news sentiment resulted in the highest forecast accuracy of 0.585 on the test data, which is superior to a random guess. The LDA (SVM) model with asset specific (news sentiment and asset specific) input features ranked first within their respective model classifiers, suggesting both BTC news sentiment and asset specific are prized factors in predicting tomorrow’s price direction.

Originality/value
To the best of the authors’ knowledge, this is the first study to analyze the potential effect of crypto-related sentiment and BTC specific news on BTC’s price using LDA and sentiment analysis.

Authors: Curto Vilsa , Bhole Monica 
Published: December 2021

AbstractObjectiveTo quantify impacts of early Affordable Care Act (ACA) Medicaid expansions on Medicaid participation for primary care physicians.Data SourcesThe study uses secondary Medicaid Analytic eXtract (MAX) data from the United States for 2009–2012, as well as secondary National Plan and Provider Enumeration System (NPPES) data from the United States for 2015.Study DesignThe study uses a quasi‐experimental difference‐in‐differences study design where the policy change is Medicaid expansion in six states that adopted early ACA Medicaid expansions during 2010 and 2011: California, Connecticut, the District of Columbia, Minnesota, New Jersey, and Washington. The key outcome variables are five monthly measures of physician participation: the number of Medicaid visits, the number of Medicaid patients, seeing at least 1 Medicaid patient, seeing at least 25 Medicaid patients, and seeing at least 50 Medicaid patients.Data Collection/Extraction MethodsThe sample consists of all physicians who were active between 2005 and 2015, according to the NPPES.Principal FindingsFor primary care physicians, Medicaid expansion led to a 29% increase in Medicaid visits (5.88 per month; 95% CI: 2.49–9.27), a 29% increase in Medicaid patients (4.59 per month; 95% CI: 2.16–7.02), and did not affect the probability of any Medicaid participation. Medicaid expansion also led to a 22% increase in the probability of seeing at least 25 Medicaid patients per month (4.58 percentage points; 95% CI: 1.27–7.89) and a 31% increase in the probability of seeing at least 50 Medicaid patients per month (2.99 percentage points; 95% CI: 0.99–4.99).ConclusionsEarly ACA Medicaid expansions led to increased Medicaid visits for primary care physicians but did not affect the probability of any Medicaid participation. Primary care physicians who had previously served Medicaid patients responded to early ACA Medicaid expansions by serving substantially more Medicaid patients.

Published: December 2021

AbstractUltrasonic treatment (UT) was used to thaw large yellow croaker in this study, and the effect of various ultrasonic power levels on the quality of large yellow croaker was evaluated after thawing. The effects of ultrasonic on water holding capacity (WHC), moisture distribution, thiobarbituric acid‐reactive substance (TBARs), total volatile base nitrogen (TVB‐N), ATP degradation (related to K value), surface color change, free amino acid (FAA) content, total sulfhydryl group (SH) content, Fourier transform infrared absorption spectra (FT‐IR), fluorescence emission spectra, and microscopic observations of large yellow croaker myofibrillar proteins were investigated. The thawing times of the control sample, 200UT, 240UT, 280UT, and 320UT samples were 1750, 1190, 810, 580, and 570 s, respectively, which indicated that ultrasonic radiation could improve thawing efficiency. Additionally, ultrasonic thawing maintained better freshness and color and inhibited lipid oxidation. Compared with fresh samples, the TVB‐N of large yellow croaker thawed by ultrasonication increased by 12.68%, and the K value increased by 0.9%. The 240UT sample had tightly arranged myofibrils and fewer changes in the structures of myogenic fibrillar proteins than the fresh samples, and the SH content of 240UT was decreased by 8.17%. Use of excessive ultrasonic power (320 W) damaged the protein microstructure and the microstructure of large yellow croaker. In conclusion, sample 240UT maintained the quality of large yellow croaker better with minimal damage, which is recommended for rapid thawing.Practical ApplicationUltrasonic waves improve the thawing efficiency of large yellow croaker and maintain the freshness and color of the fish. According to results, sample 240UT exhibited slight changes in the structure of the myofibril protein, but excessive ultrasonic power destroyed the microstructure and protein structure. Appropriate ultrasonic treatment to the thawing of fish has good prospects.

Abstract

Quantifying movement and demographic events of free‐ranging animals is fundamental to studying their ecology, evolution and conservation. Technological advances have led to an explosion in sensor‐based methods for remotely observing these phenomena. This transition to big data creates new challenges for data management, analysis and collaboration.

We present the Movebank ecosystem of tools used by thousands of researchers to collect, manage, share, visualize, analyse and archive their animal tracking and other animal‐borne sensor data. Users add sensor data through file uploads or live data streams and further organize and complete quality control within the Movebank system. All data are harmonized to a data model and vocabulary. The public can discover, view and download data for which they have been given access to through the website, the Animal Tracker mobile app or by API. Advanced analysis tools are available through the EnvDATA System, the MoveApps platform and a variety of user‐developed applications. Data owners can share studies with select users or the public, with options for embargos, licenses and formal archiving in a data repository.

Movebank is used by over 3,100 data owners globally, who manage over 6 billion animal location and sensor measurements across more than 6,500 studies, with thousands of active tags sending over 3 million new data records daily. These data underlie >700 published papers and reports. We present a case study demonstrating the use of Movebank to assess life‐history events and demography, and engage with citizen scientists to identify mortalities and causes of death for a migratory bird.

A growing number of researchers, government agencies and conservation organizations use Movebank to manage research and conservation projects and to meet legislative requirements. The combination of historic and new data with collaboration tools enables broad comparative analyses and data acquisition and mapping efforts. Movebank offers an integrated system for real‐time monitoring of animals at a global scale and represents a digital museum of animal movement and behaviour. Resources and coordination across countries and organizations are needed to ensure that these data, including those that cannot be made public, remain accessible to future generations.

Published: December 2021

AbstractObjectiveComputed tomography (CT) imaging is frequently obtained for recurrent abdominal pain after a prior emergency department (ED) evaluation. We evaluate the utility of repeat CT imaging following an indeterminate index CT in low‐risk abdominal pain adult ED patients.MethodsAn electronic search was designed for the patient‐intervention‐control‐outcome‐timing (PICOT) question: (P) adult patients with low‐risk, recurrent, and previously undifferentiated atraumatic abdominal pain presenting to the ED after an index‐negative CT within 12 months; (I) repeat CT versus (C) no repeat CT; for (O) abdominal surgery or other invasive procedure, mortality, identification of potentially life‐threatening diagnosis, and hospital and intensive care unit admission rates; and return ED visit (T), all within 30 days. Four reviewers independently selected evidence for inclusion and then synthesized the results around the most prevalent themes of repeat CT timing, diagnostic yield, ionizing radiation exposure, and predictors of repetitive imaging.ResultsAlthough 637 articles and abstracts were identified, no direct evidence was found. Thirteen documents were synthesized as indirect evidence. None of the indirect evidence defined a low‐risk subset of abdominal pain nor did investigators describe whether reimaging occurred for complaints similar to the initial ED evaluation. Included studies did not describe the index CT findings and some reported explanatory findings noted on the original CT for which repeat CTs might have been indicated. The time frame for a repeat CT ranged from hours to 1 year. The frequency of repeat CTs (2%–47%) varied across studies as did the yield of imaging to alter downstream clinical decision making (range = 5%–67%).ConclusionDue to the absence of direct evidence our scoping review is unable to provide high‐quality evidence‐based recommendations upon which to confidently base an imaging practice guideline. There is no evidence to support or refute performing a CT for low‐risk recurrent abdominal pain.
Distress Resolution through New Block Formation: Implications for Ownership Concentration*
Authors: Choy Yoonyoung 
Published: December 2021

AbstractThis study examines distress resolution under concentrated equity ownership and concentrated bank debt. Using a large sample of Korean financially distressed firms, I find that distress resolution is more likely when private placements of new equities are accompanied by a change in control. Control transfers in which new blocks are created through equity capital injection contribute to operational efficiency and long‐term performance. These findings suggest that equity capital injection and monitoring by new blockholders are essential for distress resolution under poor investor protection, which further explains why concentrated ownership may persist under such an environment.
Acculturation, urban identity, and psychological well‐being of rural–urban migrants in China
Authors: Li Yuxue , Chen Juan , Xie Shenghua , Huang Xu 
Published: December 2021

AbstractAcculturation and identity are two significant determinants of the psychological well‐being of migrants, but how they interactively affect psychological well‐being is still underexplored. This study proposes an interactional perspective that links acculturation and urban identity to the psychological well‐being of rural–urban migrants in China. Using data from the 2014 National Migrant Population Dynamic Monitoring Survey, the results of multilevel modeling indicate that both acculturation and urban identity significantly affect the psychological well‐being of rural–urban migrants. Migrants who adopt the integration and assimilation strategy show better psychological well‐being than those who adopt the separation and marginalization strategy. Rural–urban migrants who have a stronger sense of urban identity show better psychological well‐being than those with a weaker sense of urban identity. Meanwhile, urban identity and acculturation also interactively affect the psychological well‐being of rural–urban migrants. In particular, urban identity alleviates the negative pressure generated in the process of acculturation for those who adopt the acculturation strategy of separation. In addition, the effect of acculturation and urban identity on the psychological well‐being of rural–urban migrants varies by migration distance. The research contributes to the literature by demonstrating that cultural identity and place identity interactively affect the psychological well‐being of internal migrants.
