Published: June 2023

Sentiment analysis, also known as opinion mining. Social media offers users to share their conditions and opinions in their daily lives. Much of the vast amount of textual content is currently available and techniques are needed to make meaningful use of the information by separating and examining it. Sentimental analysis can explore the opinions of social media users from the point of view. During the Covid-19 pandemic, the whole world is giving comments on social media. This study aims to understand the awareness and public perception of the Indonesian people about issues related to Covid-19 on social media. Data mining was carried out on comments from users of social media accounts kawalcovid19, opponentcovid19 id, and the ministry of health with a total of 54,250 comments divided into 32,494 in the first week and 21,756 in the second week. The research method of analyzing the data includes data processing and sentiment exploration analysis. Sentiment distribution results based on the first week were positive 75.68%, neutral 16.3%, negative 13.41% while the second week was positive 80.14%, neutral 9.03%, negative 4.84%. The results are the majority of comments in Indonesian and a mixed language. Sentiment analysis shows the positive reaction of the public to the front line and all the efforts of the health ministry in fighting the pandemic. This study concludes that sentiment analysis has proven to be very effective in producing useful knowledge in the discussion of Covid-19, especially on social media, gathering public perceptions and responses about the government's Covid-19 efforts, and providing a different point of view from the current situation on the ground.

Published: June 2023

This study aims to apply a digital maturity model to measure startup performance. The maturity model consists of dimensions and criteria, which describe the area of ​​action, and maturity stages which indicate the evolutionary path to maturity. Data collection was obtained using a questionnaire given online at the startup. The research design consisted of three steps: developing a digital maturity model dimension through literature review, expert interviews, and focus groups, online surveys among individuals, and data analysis using the Rasch algorithm and cluster analysis. From these findings, it can be said that some attention should be paid to the business intelligence capacity of startups, given its impact on company performance. In addition, the effect of network learning through business intelligence is significant and presents a positive influence on performance. The results from empirical studies show that understanding the strategic importance of digitalization, as well as using digital technology for collaboration, is already practiced in most companies. However, creating a personalized customer experience based on big data analysis or process automation is characterized by a lower level of achievement. Companies are starting to carry out digital transformation more systematically and strategically, by creating measurable goals and defining roles and responsibilities within the organization. These results help practitioners as well as researchers, better understand the processes through which organizations are truly involved in their digital transformation.

The ability to lead and effectively manage change is one of the most critical factors in leadership. In today’s changes in the economy and social well-being, various leadership styles are being used, which are applied in the context of the processes of today’s globalization. Leadership has become a highly significant concept in the twenty-first-century context. The scientific literature presents and analyses various leadership styles but does not sufficiently provide practical tools to identify the possibilities of human potential and ensure sustainable management. To improve the microclimate and interpersonal trust of the institution, the most crucial role is played by leadership style, change management, creativity, and giving feedback. The article formulates tasks: to reveal the transformation of attitudes toward leadership by comparing the factors of different leadership styles that influence the team’s focus on achieving the sustainable goals set by the organization. The results of the paper show sustainability could be reached in the organization if the organization’s managers apply sustainable leadership practices.

Authors: Chen Zhi-Teng , Ye Xiao-Han
Published: June 2023

The taeniopterygid genus Taenionema Banks, 1905 currently contains 14 species distributed in the Nearctic and the eastern Palearctic Regions. Taenionema japonicum (Okamoto, 1922) is the only species known from the Eastern Hemisphere, specifically in Japan, Korea, Mongolia, Russia and north-eastern China. The authors recently described the larvae of an undetermined Taenionema species, which was supposed to represent a second Palaearctic species.

This paper reports the first endemic species of Taenionema Banks, 1905, Taenionema sinensis sp. n. from China, which also represents the second species of Taenionema from the Eastern Hemisphere. Description and illustrations based on male and female adults are provided. The new species is easily distinguished from all congeners by the bilobed abdominal sternum 9 of the male adult. The female adult is characterised by the posteriorly truncate postgenital plate. The male larva is distinguished by the emarginate subgenital plate and hook-shaped paraprocts.

Can Lorentz relativistic mass explain the lack of velocity time dilation in quasars?
Authors: Haug Espen Gaarder , Spavieri Gianfranco
Published: June 2023

Researchers in standard gravity theory and cosmology seldom take into account Lorentz relativistic mass. The dismissal of Lorentz relativistic mass by the research community has happened without first properly investigating what predictions incorporating it in gravity models have led
to. We show that the inclusion of Lorentz relativistic mass in some gravity theories has a dramatic impact on the predicted redshift from objects with high gravitational field such as stellar objects fitting the mathematical properties of black holes. Taking into account Lorentz relativistic
mass provides diverse interpretations of quasars and many other objects. As relevant example, it may explain the lack of observed velocity time dilation in quasars.
Simultaneity, language, and experience
Authors: Lundberg Randolph
Published: June 2023

As part of his special theory of relativity, Einstein introduced two definitions of the word “simultaneity”—the coordinated-clocks definition in his famous 1905 paper and the mid-point definition in his 1916 book. Einstein never discussed the relation between these
two definitions. Neither has anyone else, to my knowledge. I show that these definitions are not equivalent because they have different scopes of applicability, but that they are equivalent wherever both apply. My proof of this partial equivalence is a corollary of my proof that both of Einstein’s
definitions clash with the natural ticking of monochromatic light, which I call an electromagnetic wave clock. Einstein disparaged the idea of absolute simultaneity, but the reasons he gave were not good ones. He suggested that the idea originated in a confusion between happening simultaneously
and being seen simultaneously. This thesis is dubious. It is also irrelevant, because an idea that originates in a confusion need not be a confused idea. He suggested that there could be no experimental test for absolute simultaneity. I refute this suggestion by describing an experimental
test for absolute simultaneity, which I call the melt-mark test. The empirical credentials of Einstein’s definitions are not superior to those of absolute simultaneity. Einstein writes as if he can banish the idea of absolute “simultaneity” by merely giving the word “simultaneity”
a new meaning. But many words have multiple meanings; Einstein merely made simultaneity such a word. The meanings of “simultaneity” that there is reason to disparage are Einstein’s definitions, because they clash with the electromagnetic wave clock. None of these points is
properly appreciated by today’s physics community, where Einstein’s assertions about simultaneity continue to enjoy broad acclaim. Physical theories that employ the idea of absolute simultaneity are often wrongly rejected because they do.
The Robustness and Vulnerability of a Complex Adaptive System With Co-Evolving Agent Behavior and Local Structure
Authors: Zheng Xiaojing
Published: June 2023

Agents' irrational behavior would lead to local configuration of complex adaptive system percolation. The corresponding critical point is key to making decisions for improving the system or keeping the system from collapsing. The authors construct a complex adaptive system model where agent behavior and its local configuration co-evolve. This model shows, when an arbitrary agent and its neighbors change their strategy and local interactive configuration, how the properties of percolation critical point of this system would emerge under random attack and intentional attack. It is shown that the system is robust if it is attacked randomly, and there are always at least two large components keeping the system connected. However, if the system is attacked intentionally, the result is more interesting. The system is robust if the deleting probability is smaller than a certain critical probability c0, but the system is vulnerable if the probability is larger than c0. Furthermore, the critical probability c0 is determined by the agent payoff, system structure, and noise.

Published: June 2023

This paper aims to examine the value of different biochemical markers in predicting the outcome of COVID-19 infection. A total of 140 patients with confirmed COVID-19 infection by polymerase chain reaction (PCR), different biochemical markers were tested, their relation to the outcome of the disease was monitored, and the most reliable tests were determined. The study found a significant correlation between all evaluated biochemical markers and severity of the disease, including C-reactive protein (CRP), D-dimer, alanine aminotransferase (ALT), Aspartate aminotransferase (AST), prothrombin time (PT), activated partial thromboplastin time (aPTT). In addition, ferritin, lactate dehydrogenase (LDH), procalcitonin (PCT) and Pro- Brain natriuretic peptide (proBNP) demonstrated highly sensitivity and specificity as well as significant prognostic performance. These markers were also independently significant in predicting mortality. Early assessment of biochemical markers in patients with COVID-19 can help clinicians in tailoring treatment and providing more intensive care to those with greater mortality risk. In particular, the assessment of ferritin, LDH, procalcitonin and proBNP can independently predict mortality.

Published: June 2023

The aim of this study was to evaluate the shelf-life of pre-packaged sheep arrosticini produced in a factory located in northern Italy. Samples were divided into two series and packaged in modified atmosphere with specific gas mixtures: conventional (C: 35% O2/15% CO2/50% N2) and experimental (E: 30% CO2/70% N2). All the samples were stored at 4°C for 10 days and subjected, after 5, 8 and 10 days (t5, t8, t10), to triplicate microbiological and chemical-physical (pH, total volatile basic nitrogen, thiobarbituric acid reactive substances) analyses. At the same time, the colorimetric analysis and a sensorial evaluation were carried out (pack tightness, presence of color or odor alterations), assigning a discrete score from 0 to 5. The samples showed initial total bacterial counts close to 5 Log CFU/g: these values gradually increased during storage, exceeding the threshold of 8 Log CFU/g in the C series; lower values were detected in the E series. A similar trend was highlighted for Enterobacteriaceae, with initial loads of about 3 Log CFU/g and an increase until t10, reaching values higher than 6 Log CFU/g in the C series and close to 5 Log CFU/g in the E series (P=0.002). E. coli also showed a similar trend, although with values approximately 1 Log lower than Enterobacteriaceae. Pseudomonas spp. showed initial counts close to 4.5 Log CFU/g, with a different increase in the C series (6.5 Log CFU/g at t10) and the E series (4.95 Log CFU/g) (P=0.006). The higher growth in the C series was also observed for lactic acid bacteria, with an increase from 3 to 5 Log CFU/g (3.8 Log CFU/g in the E series P=0.016). The other microbiological parameters showed very low counts and, in most cases undetectable counts (<2 Log CFU/g) for the entire period considered. The initial values obtained from the measurement of the colorimetric indices were within the norm for this type of product: however, starting from t5, lower values of red index and lightness in the E series were measured, with an evident greying of meat surface. The results of the sensory evaluation indicated that the product showed optimal sensorial characteristics up to 8 days of shelf-life in the C series, while the use of an oxygen-free atmosphere, despite having a moderate inhibiting effect on the microbial populations, has led to an early modification of the product (5 days of storage), due to the presence of superficial greyish areas. The microbiological characteristics of arrosticini strictly depend on the hygienic conditions of slaughtering and production; even in optimal situations, the product is particularly perishable, and requires careful management of storage temperatures and times, to maintain its quality characteristics.

Published: June 2023

The application of an electrochemical (impedance) tool for monitoring Escherichia coli contamination in shellfish was evaluated after 13 months of observation. The primary aim of the present study was to compare the standard most probable number (MPN) and µ-trac 4200 (log imped/100 g) for the assessment of E. coli contamination (log MPN/100 g) in non-depurated bivalve mollusks (BM) from five sampling areas of the Veneto-Emilian coast (Italy) (118 samples). The secondary aim was to evaluate the correlation between E. coli concentrations in BM and environmental factors on a large data set (690). The methods showed a moderate, positive correlation (0.60 and 0.69 Pearson and Spearman coefficients, respectively; P<0.01) in Ruditapes philippinarum. The McNemar test indicated analogous sample classification between methods, and the impedance method overestimated the most contaminated class (P=0.03; >4,600 MPN/100 g). The results highlighted the suitability of the impedance method for a faster evaluation and routine use especially in clams, while in Mytilus it seemed less effective. Different models built by multivariate permutational variance analysis and multinomial logistic regression selected the suitable environmental features able to predict the E. coli load. Overall, salinity and season affected the E. coli contamination, whereas locally it was mainly influenced by hydrometry and salinity. The application of the impedance method coupled with environmental data analysis could help purification phase management to adhere to legal limits and could represent an advantage for local control authorities to define actions, considering extreme meteorological events' effects as a proactive reaction to climate change.

The spread of multidrug resistant (MDR) Salmonella strains, along the poultry supply chain, can represent a relevant threat to human health. This study aimed to evaluate the prevalence and antimicrobial resistance of Salmonella spp. isolated from poultry meat for human consumption. Between 2019 and 2021, 145 samples were analyzed according to ISO 6579-1:2017. The strains isolated were identified by using biochemical-enzymatic assays and serotyping, according to the Kauffmann-White-Le Minor scheme. The antibiotic susceptibility tests were determined using the Kirby-Bauer method. Forty Salmonella spp. strains were isolated and serotyping showed Salmonella Infantis to be predominant. 80% of the isolated strains were MDR and identified as S. Infantis. This study confirms the circulation of MDR Salmonella isolated from poultry meat and highlights the predominance of the S. Infantis serovar, which represents an emerging risk factor under the One Health holistic approach.

Development and Validation of a Dynamic Abdominal Pressure Twin
Sensor Finite Element Model
Authors: Yang Peiyu , Katangoori Divya , Noll Scott , Stammen Jason , Suntay Brian , Carlson Michael , Moorhouse Kevin
Published: June 2023

Some anthropomorphic test devices (ATDs) currently being developed are equipped
with abdominal pressure twin sensors (APTS) for the assessment of abdominal
injuries and as an indicator of the occurrence of the submarining of an occupant
during a crash event. The APTS is comprised of a fluid-filled polyurethane
elastomeric bladder which is sealed by an aluminum cap with an implanted
pressure transducer. It is integrated into ATD abdomens, and fluid pressure is
increased due to the abdomen/bladder compression due to interactions with the
seatbelt or other structures. In this article, a nonlinear dynamic finite
element (FE) model is constructed of an APTS using LS-PrePost and converted to
the LS-Dyna solver input format. The polyurethane bladder and the internal fluid
are represented with viscoelastic and isotropic hypoelastic material models,
respectively. The aluminum cap was considered a rigid part since it is
significantly stiffer than the bladder and the fluid. To characterize the APTS,
dynamic compression tests were conducted on a servo-hydraulic load frame under
displacement control and held at the peak compression to allow for stress
relaxation prior to slowly releasing the compression amount. The initial peak
pressures and loads were 15–17% above the level observed at a 10-second hold
period with 50% of the decay occurring within 300 ms. The material properties
are identified using an inverse method that minimizes the difference between
measured and predicted load and pressure time histories. Further, the
bio-fidelity static specifications of the APTS manufacturer are used as a basis
to identify the quasi-static material parameters. This approach resulted in a
reasonable match between physical test data and model-simulated data for dynamic
compressions of 10 mm and 15 mm (~50% compression). Additional compression tests
are conducted at two compression levels (5 and 10 mm) and at four load offset
configurations for use in the model validation. The FE model was used to predict
peak pressure responses within approximately 10% error at full-load capacity and
achieved CORA ratings >0.99 for the pressure time history. The proposed
inverse method is expected to be generally applicable to the component
characterization of other models and sizes of APT sensors.

Authors: Edino Ferdinand , Terrence Richard , Abraham Ameh
Published: June 2023

One of the cardinal goals of education in every nation is to develop the minds, creative potentials and skills of the citizens. This can be achieved through a well thought out plans and policies of government, whose constitutional responsibilities include: the formulation and implementation of workable educational policies. Therefore, this study is an attempt to explore the extent of success and failure of education policy in Nigeria with specific focus on the creative potentials and skills of Nigerian graduates for job creation and self reliance, which is one of the goals of education policy in Nigeria. To achieve its objective, the paper adopted the descriptive method of research, in which data provided and analyzed were generated from secondary sources - journals, text books, government publications and internet materials. Findings revealed amongst others that, the rate of unemployment, criminality, insurgency, kidnapping and other social vices are not only consequences of poor implementation of education policy, but also, the unemployability and inability of most Nigerian graduates to create jobs and become self reliant, form part of the resultant effects of poor standard/quality of education in Nigeria.  Based on the findings, the paper recommended, amongst others that, for Nigerian graduates to practically develop and utilize their creative potentials and skills for job creation and self reliance, teaching/learning should, indeed, be practical, activity-based, experimental and ICT supported, especially in the sciences, and entrepreneurship development. Government should not only make provisions for financial empowerment that will guarantee a smooth takeoff of creative ventures, but should also, ensure strict supervision to ensure that the money gets to the right individuals and utilized for the purpose for which it was disbursed (job creation).

Authors: Agbai Eke , Aliegba Eugene , Muhammed Bello
Published: June 2023

With pervasive international maritime security threats in the region, especially sea piracy and oil theft, Nigeria loses huge sums of money in export revenues and this reverberates on the wellbeing of residents of coastal areas whose major means of livelihood depends on the maritime sector. The purpose of this paper was to assess the impact of international maritime security threats on economic development in coastal areas of Delta and Rivers States with particular reference to unemployment and poverty levels in the areas. This paper is built around the structural conflict theory of Marxism paradigm at state-level of analysis, which is vital in the understanding of how international maritime security is related to the exploitative nature of the capitalist system, which enabled economically advanced countries to buy cheap stolen crude oil from coastal areas in Nigeria. The sample size of the study was 385 respondents drawn from a population of 9,925 people comprising of staff from Ministry of Foreign Affairs, Nigeria Customs Service, Nigeria Police Force and Nigeria Maritime Administration and Safety Agency in delta and Rivers States. The population of the study equally includes staff drawn from Togolese, Benin republic and Senegalese embassies Abuja as well as operators of shipping businesses, fishing groups and oil servicing firms in Warri, Port Harcourt, Oporoza and Bonny. Primary data were collected from close-ended and open-ended questionnaire and in-depth interview. Also, data were collected from secondary source. Data from questionnaire were analysed using simple percentages and absolute frequencies, while data from in-depth interview were analysed using narrative analytic technique. Data from secondary source were analysed using relational-content analysis.

This paper assessed the implications of Iranian nuclear deal on the politics of Middle East from the realist theoretical perspective. Data for the paper were generated from secondary sources such as books, journals, newspapers/magazines, and online materials among others. The contents of these secondary data were qualitatively analyzed. The results of this analytical discourse reveal that the deal means more of co-operation is likely to take place in the Middle East even though Iran is still perceived as a potential threat. Also, the eventual deal means the emergence of a more empowered Iran capable of dominating the region and pursuing her interests at the expense of other states. It further showed that the tendency of Iran pursuing regional hegemony is very high. The paper concludes that Iranian nuclear crisis is an indication that the intention for nuclear armament is not yet over. Based on these findings and conclusion drawn, the paper recommended that the security balance of the Middle East must be maintained in order not to experience a sudden collapse of peace and stability in the region. States in the region must be made to realize the dangers of taking measures that could lead to a race for arms, especially nuclear armament.

Published: June 2023

The paper examined the symbiotic relationship between the concepts of national interest and foreign policy, stressing that a well grafted foreign policy is dependent on a well thought-out national interest which remains a guide to a nation’s foreign policy formulation and implementation. Nigeria’s foreign policy over the years has been touted to be guided by the country’s national interest which studies in the past revealed is obfuscating. Nigeria’s national interest and her foreign policy in the past and the present, which is said to be at variance with what is obtained in other climes. In order to achieve the objective of this study, the paper adopted the theory of state capture as our guide. The paper employs the qualitative content analysis approach and relies mainly on secondary sources of data such as textbooks, journal articles, periodicals, conferences papers and the internet, etc. The study finds that there is disconnect between Nigeria’s national interest and her foreign policy objectives. Previous studies had been on Nigeria’s foreign policy and national interest without corresponding benefits to her development, but rather predicated on parochial and jaundiced sentiments. It is within this gap in foreign policy analysis literaturethat this paper investigates the need for a rethink on a well thought-out and robust national interest as a sine-qua-non for a nation’s foreign policy formulation and implementation.  In addition, instead of addressing issues raised by various studies on the unmitigated asymmetry between national interest and foreign policy objective, government are always adamant and chose to maintain the status quo. The study recommends that there is urgent need for reforms that will ensure a well defined and structured policy, for effectiveness, efficiency and transparency.

Various socioeconomic and political developments in Nigeria have necessitated avalanche of interventions of several civil society organizations (CSOs) with which they would sustain democratic practices by ensuring moral values, fundamental human rights protection, transparency and rule of law. In the daily administration of government, CSOs are seen as instruments of solution to numerous societal problems that have deprived citizens of the dividends of democracy such as neglect, insecurity, oppression and exploitation. This study focuses on the exploration of how CSOs have contributed towards sustaining democracy in Nigeria. The study is geared towards revealing the challenges that militate against the efforts of CSOs towards the sustenance of democracy in Nigeria. Qualitative method is adopted for this study, while secondary materials from books, journals, newspapers, and internet sources are utilized in accessing information. Descriptive method is used in the analysis of the sourced information. Liberal theory is deployed in the analysis of the study, as it displays the interconnectedness existing among different sectors of the society. Our findings revealed that CSOs are yet to be acknowledged as a genuine force in democratic Nigerian society. There is, also, lack of a well-structured institutional framework to support more collaboration between governmental and CSOs. The study concludes that CSOs have vital areas of contributions in the society, and are needed for Nigeria’s democratic sustenance. It is recommended that the autonomy of CSOs should be promoted to enable them perform successfully towards democratic sustenance through their policy formulation and implementation, monitoring and supervision in the society.
