Identity based encryption with equality test

ABSTRACT In this research work, we propose a notion of identity-based encryption scheme with equality Test (IBE-ET). This scheme allows authorized users to test the equivalence between two messages whereby the messages are encrypted using different previously known identities. Most existing IBE-ET researches only allows checking whether two ciphertexts encrypted under same identities contain the same message. IBE-ET has many interesting applications in constructing searchable encryption and partitioning encrypted data. However, the original IBE-ET schemes lack an authorization mechanism for a user to control the comparison of its ciphertexts with others. In this research, we propose the authorization mechanism for IBE-ET. We give the definitions of the policies and propose an IBE-ET scheme supporting these two types of authorization at the same time. Our scheme supports authorization such that receiver authorizes the tester to be able to perform equality test on all of receivers’ ciphertexts. The receiver gives the tester authorization corresponding to a specific ciphertext then the tester only acquires the equality test on that particular ciphertext. The tester without decryption can verify the equality between two ciphertexts after he or she receives two authorizations.
Seeing destinations through vlogs: implications for leveraging customer engagement behavior to increase travel intention

Purpose This study aims to understand customers’ watching experience with travel vlogs and its impacts on one of the most prominent manifestations of customer engagement behaviors (CEBs) – word-of-mouth (WOM) – and their travel intention. Drawing upon the theory of resonance, this study incorporated both cognitive and emotional aspects of travel vlog watching experience. Design/methodology/approach Online survey data were collected from 352 participants who have watched travel vlogs over the past 12 months. Partial least squares structural equation modeling (PLS-SEM) was performed for hypotheses testing. Findings The study results reveal positive impacts of source credibility, inspiration, escapism and self-congruence on WOM, which further leads to travel intention. While source credibility is the strongest predictor of WOM, more factors representing the emotional resonance turn out to be the driving factors of WOM. Research limitations/implications This study pinpoints the value of investigating audiences’ vlogs watching experience from a CEB perspective within the tourism setting. Future research is encouraged to explore more types of CEBs in the intersection of social media consumption and travel behaviors. Practical implications Travel vloggers need to convey their intrinsic passion and enthusiasm to create an emotional connection with the audiences. Hospitality and tourism marketers are recommended to promote products and services by incentivizing audiences to engage with the travel vlogs. Originality/value No prior research integrated vlogs watching experiences, engagement behavior and future travel intention in a tourism setting. This study fills this gap and contributes to the literature on customer engagement, media consumption and marketing.
Higher Martian Atmospheric Temperatures at All Altitudes Increase the D/H Fractionation Factor and Water Loss

Much of the water that once flowed on the surface of Mars was lost to space long ago, and the total amount lost remains unknown. Clues to the amount lost can be found by studying hydrogen (H) and its isotope deuterium (D), which are produced when atmospheric water molecules H2O and HDO dissociate. The difference in escape efficiencies of H and D (which leads to an enhanced D/H ratio) is referred to as the fractionation factor f. Both the D/H ratio and f are necessary to estimate water loss; thus, if we can constrain the range of f and understand what controls it, we will be able to estimate water loss more accurately. In this study, we use a 1D photochemical model of the neutral Martian atmosphere to determine how f depends on assumed temperature and water vapor profiles. We find that the exobase temperature most strongly controls the value of f for thermal escape processes. When we include estimates of nonthermal escape from other studies, we find that the tropopause temperature is also important. Overall, for the standard Martian atmosphere, f = 0.002 for thermal escape, and f = 0.06 for thermal + nonthermal escape. We estimate that Mars has lost at minimum 66–122 m global equivalent layer of water. Importantly, our results demonstrate that the value of f depends critically on nonthermal escape of D, and that modeling studies that include D/H fractionation must model both neutral and ion processes throughout the atmosphere.
The Effect of a Nature-Based Environmental Education Program on Children’s Environmental Attitudes and Behaviors: A Randomized Experiment with Primary Schools

The evidence about the effects of nature-based instruction on pro-environmentalism is uncompelling, mainly due to a lack of controlled experiments. This hinders causal claims and the provision of intervention guidelines. We present an experiment examining the impact of a nature-based environmental education (NBEE) program included in the school curriculum on children’s environmental attitudes (EA) and behaviors (EB). Children who followed the program through traditional instruction were used as a control group. Seven Spanish primary schools participated in the program and school classes were randomly assigned to the NBEE program (experimental group, N = 516) or the environmental education (EE) through traditional instruction (control group, N = 218). Our results indicate that children’s EA increased more in the NBEE group than in the control group. On average, EB remained virtually the same in both groups of children across time. In light of our findings, we encourage the promotion of a nature-based pedagogy in formal education to enhance children’s environmental attitudes.
Adaptación y validación al contexto de la actividad físicodeportiva española del Mindfulness Inventory for Sport en adultos practicantes

The objective of this study was to adapt and validate the Mindfulness Inventory for Sport (MIS) in adults in Spain, since it is the first measurement scale of mindfulness oriented to sport but there is no evidence to examine its validity in the Spanish version. For this, a sample of 337 physical exercise practitioners with an average age of 41 years was used, who were measured the mindfulness and the level of physical exercise in free time. Various descriptive, internal consistency, correlation and confirmatory factor analyzes were carried out. After confirmatory factor analysis, the scale (χ2 (33, 337) = 175.56, p = . 000, χ2/gl = 2.01, CFI = . 90, IFI = . 90, RMSEA = . 07) presented adequate values in addition to be invariant by sex These results support the three dimensions of the scale on consciousness, absence of prejudice and reorientation. The internal consistency obtained from the respective dimensions was above . 70. Consciousness correlated negatively with the absence of prejudices and positively with reorientation and physical exercise in free time, in addition, the latter correlated positively with reorientation. This study has made it possible to provide a valid and reliable scale with initial evidence to evaluate mindfulness in Spanish practitioners of physical and sports activity.
Assessment of the Impact of the Level of Disclosure of Mandatory Non-Financial Information in Public Annual Reports on the Investment Attractiveness of a Company

In this study, we assess the influence of information disclosed by issuers in annual reports in accordance with the requirements of the Central Bank of Russia on the investment attractiveness of a company. The empirical base of the research consists of annual reports of 60 Russian issuers from various industries over 10 years. On the basis of applicable regulations of the Bank of Russia we compiled an author’s dictionary of terms (word forms). Using the methods of taking into consideration grammatical forms we calculated occurrences of the dictionary terms in the texts of annual reports. This study represents the first time that a rating of issuers on the basis of the disclosure index of mandatory non-financial information (INDEX) in accordance with the Russian legislation was made. By means of a probit regression we proved the interrelation between the disclosure index of mandatory non-financial information (INDEX) and the issuer’s investment attractiveness. Additionally, by means of a panel regression we established the interrelation between the issuer’s investment attractiveness and the level of information disclosure which characterises the issuer, its securities and dividend policy, and its risk management policy.
Using Structural Family Therapy to Understand the Impact of Poverty and Trauma on African American Adolescents

Adolescence is a period in which there are many challenges due to the rapid changes in an adolescent’s mind, body, emotions, and role expectations. Living in poverty and experiencing trauma exacerbate this challenging time. The purpose of this literature review is to explore the available research surrounding African American adolescents who have experienced poverty and trauma. Additionally, the goal was to examine the literature on African American adolescents who experienced poverty and trauma conceptualized through the lens of structural family therapy. Clinical implications are provided, and additional research directions within the field of marriage and family therapy/counseling are offered with respect to the intersection of trauma, poverty, protective factors, and African American adolescents and their families.
Ethical Issues in Advanced Artificial Intelligence

The ethical issues related to the possible future creation of machines with general intellectual capabilities far outstripping those of humans are quite distinct from any ethical problems arising in current automation and information systems. Such superintelligence would not be just another technological development; it would be the most important invention ever made, and would lead to explosive progress in all scientific and technological fields, as the superintelligence would conduct research with superhuman efficiency. To the extent that ethics is a cognitive pursuit, a superintelligence could also easily surpass humans in the quality of its moral thinking. However, it would be up to the designers of the superintelligence to specify its original motivations. Since the superintelligence may become unstoppably powerful because of its intellectual superiority and the technologies it could develop, it is crucial that it be provided with human-friendly motivations. This paper surveys some of the unique ethical issues in creating superintelligence, and discusses what motivations we ought to give a superintelligence, and introduces some cost-benefit considerations relating to whether the development of superintelligent machines ought to be accelerated or retarded.
Impact Of The Covid-19 Pandemic On Anxiety And Depression Levels Of The Dialysis Center Employees

Objective: Coronavirus (COVID-19), an acute respiratory tract disease caused by a new coronavirus (SARS-CoV-2, formerly known as 2019-nCoV), first emerged in China and then drew attention spreading worldwide. In our study we aimed to determine the impact of the Covid-19 pandemic on the dialysis center employees. Methods: The healthcare professionals to take part in the study were limited to the dialysis center employees. The study used a questionnaire comprising the participants’ socio-demographic characteristics, Beck Anxiety Inventory and Beck Depression Inventory, asdata collection tool. The participants completed the questionnaire on voluntary basis in their own environment. As the Beck Anxiety Inventory and Beck Depression Inventory are grading inventories, their validity was confirmed via factor analyses. In addition their reliability analyses were conducted. In order to test the purposes of the study, the SPSS statistics software was used. The analyses were carried out at 95% (p=0.05) confidence interval. The study used descriptive statistical methods, t and ANOVA tests and correlation analysis. Results: Among the participants;54.4% are female and 79.4% are aged 26 to 49 years. 51% of the participants have encountered patients with covid, 41.2% have served patients with covid, 22.1% had covid test and tested negative. 55.9% of the participants have developed no anxiety symptoms, while 24% havedeveloped mild symptoms, 11.8% moderate symptoms and 8.3% severe symptoms. 59.3% of the participants have developed no depression symptoms, while 27.5% have developed mild symptoms, 11.3% moderate symptoms and 2% severe symptoms. It was determined that the participants’ gender, occupation (title), type of their hospital, state of encountering patients with covid and serving these patients, affected their anxiety and depression levels. Conclusion: A significant rate of anxiety and depression was determined in the healthcare professionals providing service in hemodialysis units during the Covid-19 pandemic. In all pandemics, it is necessary to carefully evaluate not only patients, but also healthcare professionals providing service to chronic patients and to take measures. Otherwise healthcare professionals who do not feel well, will not be able to provide effective service.
Ectoparasitic Infestation of Cattle in Brahmanpara Upazilla of Comilla, Bangladesh

ABSTRACT The ectoparasitic infestation of cattle around the Bangladesh was recorded high because of positive natural conditions and the cattle were discovered to be infested with several species of ticks and lice. Epidemiological examination was done amid the period from January 2013 to January 2014, of 512 Cattle examined, 364 (71.09%) were discovered to be pervaded with a few types of ectoparasites. The relationship between the sex of the animals and the ectoparasite infestation were likewise determined. The infestation rate was higher in female relative to male. The relationship between the age of cattle and the different species of ectoparasites infestation was also studied. The prevalence rate was highest in case of Rhipicephalus sanguineus (16.80%) followed by, Boophilus microplus (15.82%), Hemaphysalis bispinosa (14.84%), Haematopinus euysternus (14.45%), Linognathus vituli (09.18%). Results communicated that, adolescent dairy cattle matured 1-3 years are more (80.78%) vulnerable than that of grown-ups matured >3 years (58.53%), and young aged <1 years (61.91%). Commonness of ectoparasitic infestation in weakness status was discovered to be fundamentally more significant against such parasitic infestation than ordinary sound cattle. Seasonal prevalence showed that, higher prevalence occurred in summer season (80.74%), followed by winter (80.01%) and rainy season (60.73%). Keywords:
Assessing the histological changes in fish gills as environmental bioindicators in Paraty and Sepetiba bays in Rio de Janeiro, Brazil

The use of fish species uses as bioindicators is an important environmental monitoring tool. Histological biomarkers are adopted to assess the health conditions of different organisms and to indicate an environmental hazard. Histology can be applied as an effective method to analyze the effects of pollutants and other stressors. Accordingly, histological changes in the gill epithelium were analyzed to assess the adoption of fish species Menticirrhus americanus (Linnaeus, 1758) and Micropogonias furnieri (Desmarest, 1823) as a bioindicator to measure environmental quality in Paraty and Sepetiba bays, in Rio de Janeiro. A random sample of 58 fish was collected from the assessed bays. We found Paraty Bay to be in good conservation condition, whereas Sepetiba Bay is contaminated. The fish species collected from Sepetiba Bay showed lesions such as epithelial lifting, aneurysm, and necrosis in the gills; thus, it was possible to suggest that histological biomarkers be used bioindicators to measure the environmental impact in these bays.
Artificial intelligence and legal disruption: a new model for analysis

ABSTRACT Artificial intelligence (AI) is increasingly expected to disrupt the ordinary functioning of society. From how we fight wars or govern society, to how we work and play, and from how we create to how we teach and learn, there is almost no field of human activity which is believed to be entirely immune from the impact of this emerging technology. This poses a multifaceted problem when it comes to designing and understanding regulatory responses to AI. This article aims to: (i) defend the need for a novel conceptual model for understanding the systemic legal disruption caused by new technologies such as AI; (ii) to situate this model in relation to preceding debates about the interaction of regulation with new technologies (particularly the ‘cyberlaw’ and ‘robolaw’ debates); and (iii) to set out a detailed model for understanding the legal disruption precipitated by AI, examining both pathways stemming from new affordances that can give rise to a regulatory ‘disruptive moment’, as well as the Legal Development, Displacement or Destruction that can ensue. The article proposes that this model of legal disruption can be broadly generalisable to understanding the legal effects and challenges of other emerging technologies.
A Systematic Review of the Influence of Internal Marketing on Service Innovation

This paper aims aimed to present the trends of the literature review in internal marketing and service innovation between 1990 and 2016. The significant reason to conduct this research is that significant variables of internal marketing to link with service innovation are not clearly defined. This research yielded 22 systematic reviews of articles in the Scopus library and adopted a thematic analysis to analyze the data collected. This study provides provided answers to research questions by elaborating on overall trends, objectives, theoretical framework, methodologies, and potential variables that strongly connect between internal marketing and service innovation. While sample sizes are limited to this paper, it suggests suggested fruitful recommendations for future research to overcome this limitation. This research has had two practical implications for managers to redefine their roles and the relationship between members of the organization and to help managers and the firms to consider internal marketing efforts towards motivation, organizational culture, and organizational learning.
Effectiveness of Yellow Maize Testers with Varying Resistance Reactions to Striga hermonthica for Evaluating the Combining Ability of Maize Inbred Lines

The choice of an appropriate tester is important for success in resistance hybrid breeding programs. Limited information is available on the most suitable testers that allow the selection of yellow endosperm maize inbred lines with good combining ability for resistance to witchweed (Striga hermonthica) and superior agronomic performance in hybrids targeted to areas infested with the parasite. Testcrosses of 30 Striga-resistant yellow endosperm maize inbred lines with three testers having varying levels of resistance to S. hermonthica were evaluated at Abuja and Mokwa in Nigeria under Striga-infested and non-infested conditions in 2018 and 2019. The lines × tester interaction was significant for grain yield under Striga infestation, indicating that the performance lines in testcrosses varied with the testers. The respective average general combining ability effect of lines and testers was 1.5 and 32.4 times greater than the corresponding specific combining ability effects under infestation, showing the greater importance of additive gene action controlling the performance of testcrosses under Striga infestation. The different testers exhibited a different capacity to discriminate among the test lines with the susceptible tester being the least effective. Most of the criteria used to determine the best tester favored the selection of the tolerant and resistant testers as promising candidates to identify superior Striga-resistant yellow endosperm inbred lines for the hybridization and development of resistant hybrids. The results of this study demonstrated that testers with a high frequency of desirable alleles were superior to the tester with a low frequency of favorable alleles in hybrid breeding programs for resistance to S. hermonthica.
Stress analysis of a mode‐I crack in a 1D hexagonal quasicrystal based on the non‐local theory

This paper studies the non‐local theory solution of a Mode‐I crack in a 1D hexagonal quasicrystal (QC) by using the generalized Almansi's theorem and the Schmidt method. Based on the Fourier transform, the boundary value problem is reduced to two pairs of dual integral equations, in which the unknown variables are the displacement jumps across the crack surfaces. The dual integral equations are derived. Finally, the expression of the phonon stress field and the phason stress field at the crack tip are obtained. Numerical examples are provided to show the effects of the lattice parameter and the crack length on the phonon stress field and the phason stress field near the crack tip. Different from the classical solution, that the present solution exhibits no stress singularity at the crack tips in a 1D hexagonal QC.
Emotion Recognition of Students Based on Facial Expressions in Online Education Based on the Perspective of Computer Simulation

Online education has developed rapidly due to its irreplaceable convenience. Under the severe circumstances caused by COVID-19 recently, many schools around the world have delayed opening and adopted online education as one of the main teaching methods. However, the efficiency of online classes has long been questioned. Compared with traditional face-to-face classes, there is a lack of direct, timely, and effective communication and feedback between teachers and students in the online courses. Previous studies have shown that there is a close and stable relationship between a person’s facial expressions and emotions generally. From the perspective of computer simulation, a framework combining a face expression recognition (FER) algorithm with online courses platforms is proposed in this work. The cameras in the devices are used to collect students’ face images, and the facial expressions are analyzed and classified into 8 kinds of emotions by the FER algorithm. An online course containing 27 students conducted on Tencent Meeting is used to test the proposed method, and the result proved that this method performs robustly in different environments. This framework can also be applied to other similar scenarios such as online meetings.
Faktor yang Memengaruhi Financial Satisfaction pada Masyarakat Kabupaten Pamekasan

The purpose of this research is to determine the influence of income, debt, and financial literacy on financial satisfaction through financial management behaviour as a mediating variable. This causality research using per capita income data from BPS shows that Pamekasan district has the lowest per capita income so that Pamekasan district as an object with a total sample of 193 respondents by offline questionnaire. Using SEM techniques and processed with AMOS tools, the conclusion is that only financial literacy influences financial management behaviour because of their high savings awareness. Income does not influence financial satisfaction because even their income is high enough, but they still have high debt. Debt does not affect financial satisfaction because having debt does not necessarily cause financial anxiety. Some respondents have debt and have financial satisfaction, but some do not. Financial literacy has no influence on financial satisfaction but influences financial management behaviour, and financial management behaviour has not been able to meditate because their saving behaviour is unable to increase their satisfaction
