Attitudes, Subjective Norms, and Perceived Control Versus Contextual Factors Influencing the Entrepreneurial Intentions of Students From Poland
Authors: Kobylińska Urszula
Published: January 2022

Purpose: The article analyses the influence of personal and contextual variables on entrepreneurial intentions of students from Poland. The article presents a structural model that has been developed from a set of student perceptions. Chosen variables included in the model allows explaining and managing the formation of the intention in the context of higher education. This study provides answers to the following questions: What role and which personal variables do play importance in the formation of entrepreneurship intention in the case of young people? Which and how contextual variables are important to enhance personal variables for entrepreneurial intentions? Methodology: The research was carried out by using critical literature analysis as well as statistical research. In carrying out this work, a causal quantitative methodology (structural equation modeling) was applied using the Amos program. Factor analysis has also been used in a descriptive methodological context. The empirical research was conducted in first quarter of 2020. Findings: Research conducted on a sample of over 330 Polish students has shown that not all personal factors are statistically significant in assessing the entrepreneurial intentions of young people. As the results show, subjective norms do not play a significant role in the intention to take up self-employment. External (contextual) factors related to the broadly understood environment supporting the future entrepreneur play an important role, but much less clear than the factors at the individual level and generally indirectly influence entrepreneurial intentions, strengthening the entrepreneur's personal factors. Practical Implications: The results suppose a theoretical and practical contribution to the promotion of entrepreneur intentions of university students inside and outside the educational context. Entrepreneurship promotion programmes run by universities must focus on developing the attitude of the potential entrepreneurs, conveying the message that, despite all the obstacles that exist when launching a business, the entrepreneurship route can be an interesting alternative. Originality/Value: In the study, the personal and contextual factors influencing the entrepreneurial intentions of students were taken into account. The causal model generated on a sample of 332 Polish respondents shows the importance of individual factors on entrepreneurial intentions and the impact of contextual constructs on personal factors. Contextual variables (i.e. education, public policy, supporting entrepreneurial environments) were found to have a positive impact on personal variables as well as entrepreneurial intentions.

Published: January 2022

In developing countries, tourism positions the government not just as a policymaker, but also as a party that assists in the implementation of policies. Government initiatives towards the promotion of agro-tourism, for example, are implemented by agro-tourism-related legislation and policies. However, agro-tourism development has not been optimal due to a lack of communication and coordination between parties, as well as inadequate execution of legislation or regulations controlling agro-tourism. The purpose of this study was to assess and examine government agro-tourism legislation and policies in Indonesia. The study is qualitative in nature, evaluating and analysing ten government's agro-tourism legislation and policies, with data collected through document analysis and in-depth interviews and analysed descriptively. The findings demonstrate that the government's agro-tourism regulations include controlling cross-sectoral collaboration in agro-tourism development, certification for agro-tourism guides, the establishment of agro-tourism commissions, and agro-horticulture business arrangements, among other things. Regulations and policies are ineffectual because there is a lack of engagement, coordination, and synergy among the parties involved in agro-tourism. Collaboration is required not just in terms of bureaucracy, but also in terms of resources in order to establish, promote, and maintain agro-tourism sustainability. The suggestions and limitations of the current study are also discussed.

Published: January 2022

Road safety is the most important and main thing in traffic management. This is the shared responsibility of all elements of the nation, including regulators, law enforcement, road users, and so on. Based on this background, the purpose of this study is to determine and analyze the direct effect of Compliance and Awareness as mediating variables on the Effect of Utility and Trust in Electronic Traffic Law Enforcement on Behavior. The analysis of this research uses a survey method conducted at the intersection of Jalan Merdeka Selatan, Gambir, Central Jakarta. The population in this study were road users, namely four-wheeled drivers who passed the Jalan Merdeka Selatan intersection. The sampling technique used is non-probability sampling. The nine hypotheses gave a decision to reject the null hypothesis which means significant, meaning that each variable has a direct and significant effect on each other, namely: ETLE utility affects Compliance, Awareness, and Habits directly and significantly; ETLE trust directly and significantly influences Compliance, Awareness, and Habits; Compliance directly and significantly affects Consciousness and Habits; Awareness directly and significantly influences Habits. ETLE utility indirectly and significantly affects Compliance, Awareness, and Habits. ETLE trust indirectly and significantly influences Compliance, Awareness, and Habits. Compliance has an indirect and significant effect on Awareness and Habits. Develop a Habits in Traffic model defined by ETLE Utility and Trust mediated by Compliance and Awareness. The authenticity of this study can be seen in the indirect effect where there is still no research with the direction of such relationships and variables.
Entrepreneurship and Innovation in the Polish Industry
Authors: Zwolak Jan
Published: January 2022

Entrepreneurship is a process in which goals or tasks are set at one’s own initiative, whereby no efforts are spared to ensure their efficient and effective implementation. The concept of entrepreneurship is associated with innovation as entailing ongoing research and the introduction of rational changes and novel ideas. The aim of the research is to determine the regression interdependencies between the number of enterprises (entrepreneurship) and process and product innovation expenditure (innovators' activity) and the number of inventions (inventors' activity), and in the second regression model: also the number of enterprises (entrepreneurship) and process and product innovative expenditure (innovators' activity) and the number of patents (inventors' activities) generated within the Polish industry in the years 2015-2017. The hypothesis is that patents (inventors' activities) get reinforced with process and product innovation expenditures (innovators’ activities) employed in the process of growth of the number of enterprises (entrepreneurship) in industry, as well as the overall efficiency of expenditures and technologies (patents) in the Polish industry over the course of the researched years. Conducted studies have confirmed the above hypothesis. In addition, the research carried out has shown that patents (inventors 'activities) have supplemented the share (elasticity) of process and product innovation (innovators' activities) by 10% in the increase in the number of enterprises (entrepreneurship) as observed in industry. This share is transferred from the supply element to that of demand.

In conclusion, the high exposure to health promotion media has implications for the high compliance of students to SFS regulations.
An Analysis of the Challenges and Strategies to Improve and Strengthen the Employment Status of Persons with Disabilities in Asia
Authors: Sano Ryuhei
Published: January 2022

Over the past few decades, the employment of persons with disabilities in the Asia region has been the subject of the spotlight of several studies from various government and non-government organizations. A proper and thorough look at the employment status of persons with disabilities is a crucial aspect in the overall improvement of their rights in society, especially in terms of being free from discrimination by having equal access to decent work along with other members of society. Several transformations have occurred in the employment status of persons with disabilities. With growing potential being seen in the current world work atmosphere, persons with disabilities, with the help of technological advances, the popularity of the so-called Gig Economy, and expanding entrepreneurial spirit of the populace, the door seems to be opening wider for persons with disabilities. Given this current picture of what is happening in Asia, this paper will look at the growth of employment of persons with disabilities and its causes; the current realities and challenges, as well as possible directions that this trend is taking; and the effective strategies to further develop and promote employment of persons with disabilities.
The Relationship of Consumer Attitude and Government Regulations Towards Online Gambling Behavior in The Philippines
Authors: Prasetyawati Yuliana Riana , Lamoste Alexis Devera
Published: January 2022

The Philippine gambling industry, and particularly online gaming, has recently emerged as a major driver of the country’s economy. The rise of this controversial industry has become a cause of concern for many Filipino citizens. For the past two decades, Business Process Outsourcing (BPO) has been a major driver of the Philippine economy. However, a new sector of the economy has emerged that appears poised to take over traditional BPOs: online gambling. With the emergence of online gambling, any citizen can simply log into a website and they can play the usual casino games like poker, roulette, and slot machines or even sports betting. Online gambling is just like having a wallet in your pocket right now and just waiting for the money to come in, you just pull out your cellphone and you gamble already right away, that easy. Technically, engaging in online gambling is legal unless operated by a Philippine-licensed offshore company. Unlike other countries, the Philippines does not have strict mandates against gambling. The research aims to cover if consumer attitude and government regulations are significantly proportion with the effect of online gambling behavior. Adding to that, the researcher has added an intervening variable which is promotional ads if it has a direct impact adopting online gambling behavior. By using a quantitative analysis, the study recorded 100 respondents residing in the Philippines and studying their opinion towards this new addictive behavior relating to money. The materials and resources collected have concluded that consumer attitude and government regulations have significant impact towards this unlikely behavior, while promotional ads remain irrelevant.

Published: January 2022

Compact star-forming clumps observed in distant galaxies are often suggested to play a crucial role in galaxy assembly. In this paper, we use a novel approach of applying finite-resolution deconvolution on ground-based images of the COSMOS field to resolve 20,185 star-forming galaxies (SFGs) at 0.5 < z < 2 to an angular resolution of 0.″3 and study their clump fractions. A comparison between the deconvolved images and HST images across four different filters shows good agreement and validates image deconvolution. We model spectral energy distributions using the deconvolved 14-band images to provide resolved surface brightness and stellar-mass density maps for these galaxies. We find that the fraction of clumpy galaxies decreases with increasing stellar masses and with increasing redshift: from ∼30% at z ∼ 0.7 to ∼50% at z ∼ 1.7. Using abundance matching, we also trace the progenitors for galaxies at z ∼ 0.7 and measure the fractional mass contribution of clumps toward their total mass budget. Clumps are observed to have a higher fractional mass contribution toward galaxies at higher redshift: increasing from ∼1% at z ∼ 0.7 to ∼5% at z ∼ 1.7. Finally, the majority of clumpy SFGs have higher specific star formation rates (sSFR) compared to the average SFGs at fixed stellar mass. We discuss the implication of this result for in situ clump formation due to disk instability.

The water snowline location in protostellar envelopes provides crucial information about the thermal structure and the mass accretion process as it can inform about the occurrence of recent (≲1000 yr) accretion bursts. In addition, the ability to image water emission makes these sources excellent laboratories to test indirect snowline tracers such as H13CO+. We study the water snowline in five protostellar envelopes in Perseus using a suite of molecular-line observations taken with the Atacama Large Millimeter/submillimeter Array (ALMA) at ∼0.″2−0.″7 (60–210 au) resolution. B1-c provides a textbook example of compact

(31,3−22,0) and HDO (31,2−22,1) emission surrounded by a ring of H13CO+ (J = 2−1) and HC18O+ (J = 3−2). Compact HDO surrounded by H13CO+ is also detected toward B1-bS. The optically thick main isotopologue HCO+ is not suited to trace the snowline, and HC18O+ is a better tracer than H13CO+ due to a lower contribution from the outer envelope. However, because a detailed analysis is needed to derive a snowline location from H13CO+ or HC18O+ emission, their true value as a snowline tracer will lie in the application in sources where water cannot be readily detected. For protostellar envelopes, the most straightforward way to locate the water snowline is through observations of

or HDO. Including all subarcsecond-resolution water observations from the literature, we derive an average burst interval of ∼10,000 yr, but high-resolution water observations of a larger number of protostars are required to better constrain the burst frequency.
Mapping Physical Parameters in Orion KL at High Spatial Resolution
Authors: Wilkins Olivia H. , Carroll P. Brandon , Blake Geoffrey A.
Published: January 2022

The Orion Kleinmann-Low nebula (Orion KL) is notoriously complex and exhibits a range of physical and chemical components. We conducted high-angular-resolution (subarcsecond) observations of 13CH3OH ν = 0 (∼0.″3 and ∼0.″7) and CH3CN ν
8 = 1 (∼0.″2 and ∼0.″9) line emission with the Atacama Large Millimeter/submillimeter Array (ALMA) to investigate Orion KL’s structure on small spatial scales (≤350 au). Gas kinematics, excitation temperatures, and column densities were derived from the molecular emission via a pixel-by-pixel spectral line fitting of the image cubes, enabling us to examine the small-scale variation of these parameters. Subregions of the Hot Core have a higher excitation temperature in a 0.″2 beam than in a 0.″9 beam, indicative of possible internal sources of heating. Furthermore, the velocity field includes a bipolar ∼7–8 km s−1 feature with a southeast–northwest orientation against the surrounding ∼4–5 km s−1 velocity field, which may be due to an outflow. We also find evidence of a possible source of internal heating toward the Northwest Clump, since the excitation temperature there is higher in a smaller beam versus a larger beam. Finally, the region southwest of the Hot Core (Hot Core-SW) presents itself as a particularly heterogeneous region bridging the Hot Core and Compact Ridge. Additional studies to identify the (hidden) sources of luminosity and heating within Orion KL are necessary to better understand the nebula and its chemistry.
Dust Settling and Clumping in MRI-turbulent Outer Protoplanetary Disks
Authors: Xu Ziyan , Bai Xue-Ning
Published: January 2022

Planetesimal formation is a crucial yet poorly understood process in planet formation. It is widely believed that planetesimal formation is the outcome of dust clumping by the streaming instability (SI). However, recent analytical and numerical studies have shown that the SI can be damped or suppressed by external turbulence, and at least the outer regions of protoplanetary disks are likely weakly turbulent due to magneto-rotational instability (MRI). We conduct high-resolution local shearing-box simulations of hybrid particle-gas magnetohydrodynamics (MHD), incorporating ambipolar diffusion as the dominant nonideal MHD effect, applicable to outer disk regions. We first show that dust backreaction enhances dust settling toward the midplane by reducing turbulence correlation time. Under modest level of MRI turbulence, we find that dust clumping is in fact easier than the conventional SI case, in the sense that the threshold of solid abundance for clumping is lower. The key to dust clumping includes dust backreaction and the presence of local pressure maxima, which in our work is formed by the MRI zonal flows overcoming background pressure gradient. Overall, our results support planetesimal formation in the MRI-turbulent outer protoplanetary disks, especially in ring-like substructures.

Published: January 2022

Recent studies using volume-limited samples of brown dwarfs have revealed the photometric evolution of single L and T dwarfs and unresolved binaries as they age and cool, in particular as they transition from L to T spectral types. We demonstrate that the near-infrared photometric evolution of the resolved components of L and T dwarf binaries is consistent with that of single objects using a volume-limited sample. In addition, we provide supporting evidence that the L9 dwarf WISE J185101.83+593508.6 is an unresolved binary and identify three more candidate or confirmed unresolved binaries all from being overluminous for their spectral type. We calculate a new binary fraction of 13.1% ± 1.8% for L0–T8 dwarfs.

VIETBIO [Innovative approaches to biodiversity discovery and characterisation in Vietnam] is a bilateral German-Vietnamese research and capacity building project focusing on the development and transfer of new methods and technology towards an integrated biodiversity discovery and monitoring system for Vietnam. Dedicated field training and testing of innovative methodologies were undertaken in Cuc Phuong National Park as part and with support of the project, which led to the new biodiversity data and records made available in this article collection.

VIETBIO is a collaboration between the Museum für Naturkunde Berlin – Leibniz Institute for Evolution and Biodiversity Science (MfN), the Botanic Garden and Botanical Museum, Freie Universität Berlin (BGBM) and the Vietnam National Museum of Nature (VNMN), the Institute of Ecology and Biological Resources (IEBR), the Southern Institute of Ecology (SIE), as well as the Institute of Tropical Biology (ITB); all Vietnamese institutions belong to the Vietnam Academy of Science and Technology (VAST).

The article collection "VIETBIO" (https://doi.org/10.3897/bdj.coll.63) reports original results of recent biodiversity recording and survey work undertaken in Cuc Phuong National Park, northern Vietnam, under the framework of the VIETBIO project. The collection consist of this “main” cover paper – characterising the study area, the general project approaches and activities, while also giving an extensive overview on previous studies from this area – followed by individual papers for higher taxa as studied during the project. The main purpose is to make primary biodiversity records openly available, including several new and interesting findings for this biodiversity-rich conservation area. All individual data papers with their respective primary records are expected to provide useful baselines for further taxonomic, phylogenetic, ecological and conservation-related studies on the respective taxa and, thus, will be maintained as separate datasets, including separate GUIDs also for further updating.

Bibliometric analysis of research on renewable energy crowdfunding: An assessment and policy implications
Authors: Cézanne Cécile , Rigot Sandra , Saglietto Laurence
Published: January 2022

Crowdfunding is a new form of financial intermediation that has been used to fund renewable energy projects. However, research on the significance and evolution of renewable energy crowdfunding is scarce. The present paper provides a bibliometric analysis of the existing academic work on renewable energy crowdfunding. We identify three main clusters of publications: (1) renewable energy crowdfunding as an innovative solution to the technological and financial barriers to the deployment of renewable energy, (2) the success factors of crowdfunded renewable energy technologies, and (3) the links among the private actors involved in the energy transition. We show that the literature on renewable energy crowdfunding overlooks public interventions. We suggest that the state support crowdfunding to promote the development of renewable energy projects, and we discuss state interventions and the role of the state in regulation and investment.JEL classification: D14, Q28, Q48.
Case History for the Pediatric Eye Examination
Authors: Moy Amy
Published: January 2022

The art of taking a patient's case history is essential for a solid understanding of pertinent details before proceeding with an examination. While establishing rapport with the patient, the clinician should ask questions about birth history, developmental history, educational and social history. Active listening skills and flexibility of the provider are useful tools for an effective start to the examination. This chapter reviews categories of questions needed for optimization of case history for the pediatric patient. This includes questions focused on specific age categories, including infants and toddlers, preschoolers, elementary-aged children, and adolescents. The chapter author provides clinical pearls for a more efficient and effective exam, including a section on assisting children with special needs.
Binocular Examination in Children
Authors: Bansal Surbhi , Shoge Ruth Y. , Meiyeppen Siva
Published: January 2022

This chapter introduces the reader to tests commonly performed in a binocular vision examination to determine a child's binocular status. The testings introduced in this chapter are all chairside techniques that do not involve a significant amount of extra equipment or time. The binocular examination consists of determining the ocular position and then accommodation, vergence, and ocular motor statuses. The ocular position consists of determining where the eyes point in space and if they are correctly aligned. Evaluation of ocular alignment and the ability to move the eyes with coordination can be determined with various techniques, including Hirschberg, Krimsky, cover test, as well as Modified Thorington, motor testing, and vergence ranges. This chapter will familiarize the clinician with the basics of binocular vision testing and improve the reader's comfort with the various elements of the binocular vision examination.

This chapter provides an overview of accommodation testing on pediatric patients in the clinical setting. The author describes the indications for accommodation testing and provides clinical pearls for testing accommodative function in children. The chapter covers the specific tests, equipment required, and step-by-step procedures for testing accommodative amplitude, accommodative response, and accommodative facility.
Diagnostic Agents in the Pediatric Eye Examination
Authors: Zhu-Tam Lily
Published: January 2022

In this chapter, the author reviews the most common topical ophthalmic drops for diagnostic use in a pediatric eye exam. Topical diagnostic agents have become an integral part of an ocular health examination even in infants and young children. Topical local anesthetics are commonly used for eye procedures such as tonometry, gonioscopy, and minor office procedures. The proper use of mydriatic drugs allows clinicians to identify and diagnose various ocular abnormalities that might otherwise go undetected. Cycloplegic refraction is a reliable procedure to determine the true refractive status of patients with accommodative esotropia, pseudomyopia, and latent hyperopia. Cycloplegic refraction is also useful in non-communicative or uncooperative patients and when a functional vision problem is suspected such as when visual acuities do not correlate with symptoms or clinical expecteds. Many times, diagnostic drops can help a clinician be more confident of the patient's clinical findings.
Slit Lamp Examination on Pediatric Patients
Authors: Khattar Alanna
Published: January 2022

Slit lamp examination is an important component of a pediatric eye exam. The slit lamp instrument, also known as a biomicroscope, is used to provide a stereoscopic magnified view of the ocular structures. The slit lamp facilitates the examination of both the anterior segment as well as the posterior segment of the eyes. For posterior segment examination, handheld lenses are used in conjunction with the slit lamp. Different tools and examination techniques are often needed to examine infants, toddlers, and other pediatric patients who cannot be positioned in the slit lamp. This chapter discusses the techniques and equipment used to facilitate the ocular health examination, including anterior segment structures, posterior segment structures, and intraocular pressure measurements in the pediatric population.
Ocular Emergencies in Children
Authors: Harewood Joy , Khattar Alanna , Bass Olivia
Published: January 2022

This chapter covers general bedside and chairside examination procedures and instruments used to examine a pediatric patient in an acute care setting. Pediatric patients may present to an emergency room or present emergently in any clinical setting with a wide variety of acute ocular conditions. When working in an emergency room or hospital-based setting, it is unlikely that a clinician will have all of the exam equipment typically used for routine care. The authors review the various ocular imaging techniques used to obtain a view of the internal structures of the eye, orbit, head, and brain when external examination is not sufficient. The procedures described aid the clinician in appropriately and thoroughly evaluating pediatric patients presenting with ocular emergencies.

Published: January 2022

Social media platforms play a tremendous role in the tourism and hospitality industry. Social media platforms are increasingly becoming a source of information. The complexity and increasing size of tourists' online data make it difficult to extract meaningful insights using traditional models.

Authors: Ramya S. P. , Eswari R.
Published: January 2022

Automatic fake news detection is a challenging problem in deception detection. While evaluating the performance of deep learning-based models, if all the models are giving higher accuracy on a test dataset, it will make it harder to validate the performance of the deep learning models under consideration. So, we will need a complex problem to validate the performance of a deep learning model. LIAR is one such complex, much resent, labeled benchmark dataset which is publicly available for doing research on fake news detection to model statistical and machine learning approaches to combating fake news. In this work, a novel fake news detection system is implemented using Deep Neural Network models such as CNN, LSTM, BiLSTM, and the performance of their attention mechanism is evaluated by analyzing their performance in terms of Accuracy, Precision, Recall, and F1-score with training, validation and test datasets of LIAR.
Evaluation of the Effect of the Difference between the Real Attachment Unit and the Sealing in the Study of the Stress-Strain State of the Solar Panel of a Small Spacecraft as a Result of a Temperature Shock
Authors: Sedelnikov A.V. , Serdakova V.V.
Published: January 2022

The author of this scientific paper studies the stress-strain state of the solar panel of a small spacecraft after a temperature shock. The temperature shock is caused by the entry or exit of a small spacecraft into or out the Earth's shadow. In this work is considered a one-dimensional model of thermal conductivity. It is assumed that the solar radiation flux falls properly on the solar panel. Violation of normality due to deformations is neglected. A special feature of this work is to take into account the actual fixing of the solar panel. The boundary conditions in the form of a seal are preserved. However, the mobility of the smallest spacecraft is taken into account as a result of the occurrence of a longitudinal force in the solar panel during a temperature shock. The results are compared with the simulation data without taking into account the mobility of the small spacecraft. The results of this work can be used in the design of small spacecraft for technological purposes to meet the requirements for microaccelerations.

Published: January 2022

In recent years, photoelectric performances of many low-dimensional metal halide hybrid materials have been researched and utilized in the domain of phosphors, light emitting diodes (LEDs) and photoelectric detection etc. Nevertheless, unlike two-dimensional (2D) ones, one-dimensional (1D) hybrids received less attention to study their structures and optical properties. Herein, we deal with luminous performance and photoluminescence mechanism for an original 1D organic-inorganic lead chloride hybrid C5H14N3PbCl3 which is abbreviated as TMGPbCl3 (TMG+ = 1, 1, 3, 3-tetramethyguanidine cation). According to photoluminescence spectra, its broadband white-light luminescence are dual emissions from organic component TMG+ peaked at 429 nm and self-trapped excitons (STEs) of inorganic metal halide octahedra peaked at 510 nm, respectively and this property make it to be a promising white-light phosphor.
