Modeling Of Conceptions Of Health: A New Tool In Health Education
Authors: JAVERLIAT Pascal , Pizon Frank , Gerbaud Laurent
Published: March 2020

BACKGROUND: Conceptions allow individuals to interpret reality and to act on it according to their own form of coherence and validity. If a student’s conception of health is not organized at the beginning of the course so as to accept that the three domains of the biopsychosocial concept act on an equal footing, it is possible that notions brought by the instructors, relating to a domain that the student considers less operational, are too far removed from his proximal zone of development. This article proposes to shed light on this issue through an analysis, leading to a modeling of students’ conception of health at the beginning their osteopathy studies.METHODS: A semi-directed questionnaire survey was conducted among osteopathy students during their first week of training. The contents of the verbatims were analyzed according to their blocks of meaning, categorized to bring out the different conceptions of health and then modeled using network visualization software to illustrate the links and the relative weight of the different items of conceptions.RESULTS: We identified 36 categories of conceptions of health. The modeling shows strong links between the psychological and biological domains, while the social domain is isolated.CONCLUSIONS: From an andragogical perspective, modeling conceptions of health can allow students to situate their life course in relation to health and instructors, in order to identify the components of health conceptions that they do not yet mobilize.

Background: With the development of medical education, new teaching method, such as flipped teaching model, was paid attention in the process. However, the sharing elaborate courses was used in the flipped teaching model in basic medicine has not been well investigated. Therefore, the aim of this study was to evaluate students’ learning effect of the histology and biochemistry between traditional teaching methods and flipped teaching method in the basic medicine classes to provide a scientific evidence of a new model establishment in the medical students’ education.Methods: 180 medical students at the Dalian Medical University were enrolled in the process. Hyperthyroidism was chosen for the content of this study. The participants were randomly allocated into the common teaching model group with the traditional lecture-based manner or the flipped teaching model group with the sharing elaborate courses manner. There are paper test, online test and lab test for histology and embryology after learning. The scores including total score, paper test score, online test score and lab test score were compared in two differernt teaching model and students were required to complete the questionnaire to evaluate the teaching model.Results: The scores of total, online and lab test with flipped teaching model were higher than those in common teaching model in histology and embryology. Additionally, the scores of total, paper and lab test with flipped teaching model were higher than those in common teaching model in biochemistry.The feedback of all items in the questionnaires were much positive. More students agreed and accepted the flipped teaching method could help to improve their performance.Conclusions: The medical students at Dalian Medical University can benefit from the flipped classroom teaching model, and a flipped classroom teaching model may well serve some subject areas such as histology and biochemistry. The flipped classroom approach can serve as a potentially exciting new modality for teaching model in the future.

Published: March 2020

Background To study the effect of DNA methyltransferase (DNMT1) on Marveld1 in hepatocellular Carcinoma (HCC), and explore its role in the molecular mechanism of HCC occurrence and development. Methods The expression levels of Dnmt1 and Marveld1 genes were detected by RT-PCR in the intraoperative pathological specimens. The human hepatoma Bel7402 and SMMC7721 cell lines down-regulated by DNMT1 gene expression were constructed by SiRNA transfection. The methylation level of Marveld1 promoter region was detected after RT-PCR and West-blot verification. The expression of Marveld1 gene, cell proliferation, invasion and change of cell cycle were detected by RT-PCR and West-blot. The expressions of P53, CyclinD1, and P21 and P16 protein were detected by West-blot method. Results The expression of DNMT1 gene in human hepatocarcinoma tissues was higher than that in adjacent tissues. The methylation level of the Marveld1 gene promoter region in human hepatoma cell line down-regulated by DNMT1 gene expression was decreased, the expression level of Marveld1 gene was increased, and the proliferation and invasion ability of cells were weakened. The cell cycle was showed as G1-S phase arrest; P53 and P16 protein expressions were up-regulated, and CyclinD1 and P21 protein expressions were down-regulated. Conclusions Dnmt1 gene is highly expressed in human hepatocarcinoma tissues. Down-regulation of DNMT1 gene expression can decrease the methylation level of Marveld1 promoter region, up-regulate Marveld1 gene and human P53 and P16 proteins expressions, and down-regulate CyclinD1 and P21 proteins expressions, inhibit the proliferation and invasion of human hepatoma cells and can cause cell cycle G1-S arrest.

Published: March 2020

In order to establish the dynamic model of redundant robotic arm more accurately, this paper studies the identification method of the dynamic parameters of redundant robotic arm. A method of introducing the theory of spins based on the Newton-Euler dynamics equations, and using the Coulomb + viscous friction model to further derive the minimum parameter set through linearization is proposed. The method of offline identification of current measurement is used to realize the parameter identification of the robotic arm. The excitation trajectory is designed in the basic form of Fourier series. The non-linear optimization function is used to optimize the coefficient of the trajectory with the minimum number of conditions in the observation matrix as the goal Therefore, the available joint trajectories are obtained, and the obtained parameter set has high accuracy and can meet the needs of actual control. Finally, the method was experimentally tested by actual robot Walker, which verified the accuracy and effectiveness of the proposed method.
The Role of African Court on Human and Peoples’ Right for Human Rights Protection: The Case of Libyan Crises
Authors: Antigegn Getahun Kumie
Published: March 2020

The emergence of regional human rights systems depicts one of the greatest achievements in the internationalization of human rights. The foundation of the charter paved the way for the birth of the court thereafter. The African Court is established by virtue of the 1998 protocol to the Charter and the court is built upon an arsenal of protective and remedial techniques. The establishment of the court has reset the stage and created a new platform for the protection of human rights in Africa. The cardinal objective of the paper is to investigate the role of African Court on human and Peoples’ rights protection in Libya Crises taking the case of Saif Al Islam Gaddafi. The paper has utilized qualitative methodology. The government of Libya responded with brutal force against civilian protesters in contravention of international human rights and humanitarian law. The security force of the government of Libya killed many protesters as well. This situation intensified human rights violations and enforced many of the peoples to displace. The court issued an important ruling in March 2011, ordering provisional measures against Libya in the armed conflict in its territory. Libyan government denied the claims of human rights violations in its territory and showed its willingness to subject itself to criminal investigations by the Court if necessary. The issue of the fund, independence, commitment and competence of judges to interpret mandate and jurisdiction, the willingness of the states to support and to abide by court decisions, and powers of the concerned body to enforce court decisions hampered the court from being effective. Generally, unless African States act in good faith with respect to the decisions of the African Human Rights Court, the court becomes no more significant.

Published: March 2020

El escenario del posacuerdo colombiano, plantea la necesidad de visibilizar a la naturaleza como víctima del conflicto armado, interpelando nuevas concepciones de justicia más allá de la mirada eminentemente antropocéntrica. Para asumir este debate se abordan los tipos de violencia sufridos por la naturaleza de lo no humano, desde las categorías de violencia estructural y cultural, hasta la categoría de violencia directa asociada al conflicto armado; así mismo se aborda el enfoque de los derechos bioculturales como uno de los fundamentos para reconocer a la naturaleza como víctima del conflicto armado, pero con el problema de continuar reproduciendo narrativas propias de la violencia cultural y estructural.

Dynamics of a single mass vibrating system impacting into a deformable support
Authors: Ragulskis K. , Ragulskis L.
Published: March 2020

The investigated system comprises a mass attached by a deformable link to a fixed foundation, and an elastic-dissipative limiter of motion of that mass. Such types of systems are widely used in different technological devices and machines. This paper is devoted for the improvement of dynamical qualities of such systems. Free and forced stationary harmonic vibrations as well as the qualitative parameters of motions of the system are analyzed in this paper. Characteristics of vibrations are determined using analytical and numerical techniques. It is determined that for the case of zero fastening the values of eigenfrequencies of the system do not depend on the amplitude of excitation. Then the system has an infinite number of multiple eigenfrequencies. In the case of forced harmonic excitation single valued stable motions exist in the vicinity of the resonance. This gives rise to some qualities of the system which are useful in practical applications.

Specificity of the development and characteristics of mixed damage to network structures of pipeline transportation systems
Authors: Tararychkin I. A.
Published: March 2020

Pipeline transportation systems are used in various industries for the purpose of delivering various substances and materials to consumers. If, as the result of an accident development, a certain number of random linear elements (pipelines) consecutively fail, such scenario of events is called progressive damage. If several pipelines converging at a node fail simultaneously, such point element of the system is blocked. Progressive blocking of a certain set of nodes of a pipeline system in random order is called a progressive blocking. Simultaneous development within a system of progressive damage to linear elements and blocking of transportation nodes represents mixed damage. Mixed damage is a hazardous form of emergency, and its development causes fast degradation of a system’s transportation capabilities.

TheAimof the paper is to study the characteristic properties and patterns of the progress of mixed damage affecting network structures of pipeline systems, as well as evaluating such systems’ capability to resist its development.

Methods of research.The characteristics of network entities’ resilience to the development of mixed damage were identified by means of computer simulation. The nature of the effects to which a system is exposed was defined with a cyclogram, whose integer parameters indicate the alternation of the process of sequential damage of linear elements and nodes of a network structure.

Results.It has been established that a correct comparison of the resilience of various network structures to mixed damage is only possible with regard to comparable facilities. For that purpose, the analyzed systems must have identical numbers of nodes, linear elements and end product consumers. Additionally, such systems must be exposed to effects with identical cyclograms. It is shown that the correlation of the resilience of comparable network structures does not depend on the specific type of mixed damage cyclogram, but is defined by the nature of the connections within a particular system.

Conclusions.Mixed damage is a hazardous development scenario of an emergency situation that is associated with rapid degradation of the transportation capacity of pipeline systems. The ability of network structures of pipeline systems to resist mixed damage is evaluated based on indicators that are defined by means of simulation. A correct comparison of the resilience of various structures to mixed damage is only possible in case they are comparable. For that purpose, they must have identical numbers of nodes, linear elements and product consumers. Additionally, such systems must be exposed to damage procedures with identical cyclograms. The correlation of the resilience of network structures that comply with the comparability conditions does not depend on the adopted damage cyclogram, but is defined by the existing set of connections within a particular system.
Acute Myocardial Infarction in Systemic Mastocytosis: Case Report With Literature Review on the Role of Inflammatory Process in Acute Coronary Syndrome
Authors: Battisha Ayman , Sawalha Khalid , Madoukh Bader , Sheikh Omar , Doughem Karim , Al-Akchar Mohammad , Al-Sadawi Mohammed , Shaikh Shakil
Published: March 2020

Background:

Systemic Mastocytosis (SM) is a disorder of excessive mast cell infiltration
in multiple organ tissues. Atherosclerosis is a major risk factor for developing acute coronary
syndrome. In addition to lipid accumulation in the arterial wall, inflammation plays an important
role in the pathogenesis of plaque rupture and activating the thrombosis cascade. The Mast cells
contribution to plaque destabilization has been well established in multiple animal and human studies.
In a recent study, SM has been proven to be associated with a higher incidence of acute coronary
syndrome even with lower plasma lipids levels. The study showed that 20% of patients with
SM had cardiovascular events compared to only 6% in the control group with adjustment to all cardiac
risk factors.

Case:

We presented a patient with no risk factors for heart disease other than old age and history of
SM who developed acute myocardial infarction.

Conclusion:

SM can be life-threatening and can result in ACS, anaphylactic reaction, syncope, or
cardiac arrest. Clinicians should have a high index of suspicion of acute coronary syndrome (ACS)
occurrence in the setting of inflammatory conditions, such as SM and KS, and vice versa, where
SM should be considered or ruled out in patients who suffer from anaphylaxis and cardiac arrest or
myocardial infarction.

Published: March 2020

Background:

Tumors are defined as abnormal tissue masses, and one of the most important
factors leading to the growth of these abnormal tissue masses is Vascular Endothelial Growth
Factor, which stimulates angiogenesis by releasing cells under hypoxic conditions. Hypoxia has a
vital role in cancer therapy, thus it is important to monitor hypoxia. The hypoxia marker Pimonidazole
(PIM) is a candidate biomarker of cancer aggressiveness.

Objective:

The study aimed to perform radioiodination of PIM with Iodine-131 (131I) to join a theranostic
approach. For this purpose, PIM was derived as PIM-TOS to be able to be radioiodinated.

Methods:

PIM was derived via a tosylation reaction. Derivatization product (PIM-TOS) was radioiodinated
by using iodogen method and was analyzed by High-Performance Liquid Chromatography
and Liquid chromatography-mass spectrometry. Thin layer radiochromatography was utilized
for its quality control studies.

Results:

PIM was derived successfully after the tosylation reaction. The radioiodination yield of
PIM-TOS was over 85%.

Conclusion:

In the current study, radioiodination potential of PIM with 131I, as a potential theranostic
hypoxia agent was investigated. Further experimental studies should be performed for developing
a novel hypoxia probe including theranostics approaches.
A Maximum Entropy Estimator for the Average Survival Time Differences between Two Groups
Authors: Manciu Marian , Hosseini Sorour , Guzman-Gonzalez Joscelyne
Published: March 2020

Background:

Statistical methods commonly used in survival analysis typically provide the
probability that the difference between groups is due to chance, but do not offer a reliable estimate of
the average survival time difference between groups (the difference between median survival time is
usually reported).

Objective:

We suggest a Maximum-Entropy estimator for the average Survival Time Difference
(MESTD) between groups.

Methods:

The estimator is based on the extra survival time, which should be added to each member of
the group, to produce the maximum entropy of the result (resulting in the groups becoming most similar).
The estimator is calculated only from time to event data, does not necessarily assume hazard proportionality
and provides the magnitude of the clinical differences between the groups.

Results:

Monte Carlo simulations show that, even at low sample numbers (much lower than the ones
needed to prove that the two groups are statistically different), the MESTD estimator is a reliable predictor
of the clinical differences between the groups, and therefore can be used to estimate from (low
sample numbers) preliminary data whether or not the large sample number experiment is worth pursuing.

Conclusion:

By providing a reasonable estimate for the efficacy of a treatment (e.g., for cancer) even
for low sample data, it might provide useful insight in testing new methods for treatment (for example,
for quick testing of multiple combinations of cancer drugs).
Peculiarities of Spondylitis in the Patients Undergoing Program Hemodialysis (Case Report)
Authors: Mushkin M. A. , Dulaev A. K. , Tsed A. N.
Published: March 2020

Relevance. The surgical treatment of spinal diseases and injuries in the patients on hemodialysis is one of the most complicated problems of the spine surgery, since such a surgery is associated with an increased risk of infectious complications and perioperative mortality. The case description. A 59-year-old female came to the clinic complaining back pain. Th8-9 vertebrae spondylitis complicated by an epidural and paravertebral abscess with pertinent neurological disorders and bilateral pneumonia were diagnosed. The patient had been on hemodialysis for 18 years due to the end-stage chronic kidney disease complicated by uremic osteodystrophy. The surgical debridement and stabilization of the spine were performed in one stage posterior approach using a titanium mesh implant in combination with autologous bone and posterior instrumentation. A regression of neurological disorders and the pain syndrome relief were achieved. In the late postoperative period, the instability of the posterior fixation developed twice, requiring restabilization. Within the following 3.5 years after the operation, the pain syndrome had not returned. Conclusion. The presence of equipment for hemodialysis and a multidisciplinary approach allow to achieve the positive results in the surgical treatment of inflammatory diseases of the spine in the patients with endstage chronic kidney disease.

Prosthetic joint infection (PJI) after primary hip arthroplasty (PHA) in most cases results in severe surgical and socio-economic problems. Along with improving the technical support of arthroplasty and antibiotic prevention schemes, a key point in reducing the rate of infectious complications is predicting of PJI in each individual patient. The purpose of the study was to reveal the key features of our patients with infectious complications after PHA in comparison with the patients with a successful outcome of arthroplasty. Materials and Methods. The outcomes of 249 cases of PHA were evaluated retrospectively. 115 of them subsequently developed PJI (main group) and 134 were without infectious complications (control group). The comparative analysis of the groups was aimed at identifying the key preoperative, intraoperative and postoperative factors for PJI, as well as combinations of the factors characteristic for our patients. Results. The risk group for the development of infectious complications included patients undergone hip surgery (p0.001), body mass index 40 kg/m2 (p = 0.170), preoperative hemoglobin 115 g/L (p = 0.063), duration of the operation 90 min (p0.001), intraoperative blood loss 410 ml (p0.001), CRP 69 mg/L on day 4 th to 5 th after PHA (p0.001), as well as a combination of 4 or more of the above factors (p0.001). Conclusion. We believe that the correction of the management tactics of such patients taking into account the identified risk factors will reduce the incidence of PJI after PHA.

Published: March 2020

Область архитектуры и строительства ввиду большого вли­яния на окружающую среду является объектом регулирования посредством экологических доктрин. Однако в области про­фессионального и высшего архитектурного и строительного образования до настоящего времени не внедрена комплексная программа экологического образования. Ещё больше вопросов вызывает область градостроительного образования.

Ориентация деятельности на стратегию устойчивого развития заставляет архитектора и градостроителя искать адекватные и эффективные ответы на вызовы современности, опираясь на принципы этой стратегии.

В 2013 году в МАРХИ была разработана и в 2014-ом утверж­дена Концепция экологического образования. Предпосылки к её внедрению заложены в самой профессии архитектора и градостроителя, осуществляющих преобразование природ­ного ландшафта в антропогенный. Цель Концепции, с одной стороны, обеспечить непрерывность процесса формирования экологического мышления на всех этапах учебного процесса, с другой стороны, она позволяет задействовать в архитектур­ном проектировании инновационные технологии в области экологического строительства, разработанные специалистами инженерных кафедр.

Сущность интегрированного архитектурного образования в овладении способностью разрабатывать и реализовывать со­циально-философскую идею устойчивой среды обитания для конкретных условий региона, города на основе современных научных и технических достижений в области градостроитель­ства, архитектуры, экологической безопасности, конструкций, строительной физики и строительных материалов.

В основе этого подхода, названного «Интегрированное архитектурное образование», ориентированные на Стратегию устойчивого развития:

разработанная многоуровневая система интегрирован­ного устойчивого образования;

проектирование объектов как устойчивых архитектурно­инженерных умных систем;

рейтинговая система оценки здания на протяжении всего жизненного цикла - от проектирования до различных стадий эксплуатации.

На примере работ по сохранению объекта культурного на­следия (ОКН) регионального значения «Усадьба Михалково» в Москве рассмотрены методология и методика проектирова­ния парковой реставрации и задачи их совершенствования.

В 1784-1788 годах в Михалкове в стиле «псевдоготики» был построен архитектурный ансамбль парадного двора (архитектор В.И. Баженов) и устроен обширный пейзажный парк, куда вошли уже существовавшие в ту пору регулярный парк с копаными прудами и Головинские пруды.

Площадь ОКН «Усадьба Михалково» более 50 га. «Ядро усадьбы», включающее ансамбль парадного двора с регулярным парком - ОКН федерального значения, имеет площадь около 8 га.

Анализ архивных материалов и натурные обследования показали, что архитектурно-пространственная и ландшафтная организация изучаемого произведения СПИ соответствуют основным принципам создания русских пейзажных парков этого периода, особенно парков, характерных для творчества В.И. Баженова и его последователей.

На примере ОКН «Усадьба Михалково» показано, как про­счёты в оценке композиционных «особенностей» пейзажных парков, их сохранности, отсутствие в «предмете охраны» цен­ных элементов ландшафта могут негативно влиять на резуль­таты парковой реставрации. Для Михалково рекомендовано углублённое изучение композиционных особенностей пей­зажного парка, доработка «предмета охраны», исправление недостатков недавно выполненной парковой реставрации. Изучение опыта выполненных работ по реставрации и при­способлению к современному использованию имеет значение как для будущих реставраций рассматриваемого парка, так и для других исторических парков.

Procuramos compreender como a Educação Física tem se organizado no mercado de trabalho com a expansão das possibilidades de atuação nos últimos anos. Nos apropriamos do ponto de vista da Sociologia das Profissões como lente teórica e caracterizamos o estudo como descritivo, com base em dados extraídos no banco de microdados da RAIS – Relação Anual de Informações Sociais de 2014. Como resultados, observamos um contingente de profissionais jovens, a maior presença das mulheres nos diversos setores de atuação e a baixa permanência no emprego formal por longo período de tempo. Observamos grande variabilidade na remuneração em diferentes estados, assim como entre gêneros. Concluímos ser necessário o investimento em novas análises sobre o contexto macrossocial da profissão, considerando que a carreira na Educação Física está condicionada às contingências sociais, políticas, culturais e econômicas na sociedade.
Changes of bird behavior in response to magnetic fields anomaly before the earthquake: a review
Authors: Fadilah Muhyiatul , Riandi Riandi , Permanasari Anna , Maryani Enok
Published: March 2020

Animal behavior is a response to external environmental conditions through detection by certain senses. Changes in physical factors in the environment before the earthquake (magnetic field anomaly) also influence the expression of specific behavioral changes in birds, namely the flight activity. However, scientific explanation of changes in orientation or direction of flight before the earthquake was not yet available. This article aims to describe the mechanism of bird's biological response to changes in the magnetic field before the earthquake. This study is a literature review. The results of theoretical synthesis explain that birds use magnetic receptors and light receptors that recognize changes in the magnetic field before the earthquake followed by an increase in the amount of intracellular calcium ions. Abnormal amounts of calcium stimulate the formation of more ATP which activates the function of actin and myosin, therefore muscle cells experience a bathmotrope effect expressed in the form of changes in flight direction.

El análisis de las concepciones teóricas de la comunicación permite identificar la importancia que se le concede a ésta en la formación del hombre; la comunicación debe ser estudiada como objetivo y contenido del currículo o como un saber transversal. El objetivo de esta investigación es caracterizar la comunicación interpersonal en el proceso enseñanza-aprendizaje en la Licenciatura en Educación de la Universidad de Guayaquil (Ecuador). Los instrumentos utilizados fueron la observación y el cuestionario; la muestra estuvo conformada por 62 profesores y 355 estudiantes. Como principales resultados se aprecian limitaciones en la proyección didáctica de la comunicación interpersonal en el proceso enseñanza-aprendizaje, lo cual se evidencia en la falta de diálogo, carencia de actividades grupales durante las clases e insuficiencia en la personalización del proceso, entre otras.

OBJECTIVE

To determine whether a dose-response relationship exists between short-term oral prednisone administration and common clinicopathologic variables, cardiovascular biomarkers, and systolic arterial blood pressure (SAP) in healthy dogs.

ANIMALS

8 healthy Beagles.

PROCEDURES

Dogs underwent five 5-day experiments (no prednisone treatment [control condition] and prednisone administration at 0.5, 1, 2, and 4 mg/kg, PO, q 24 h), with a 9-day washout period between protocols. Analyses performed before and after treatments included a CBC, serum biochemical analysis, and determination of SAP, fractional excretion of electrolytes, urine protein-to-creatinine ratio, glomerular filtration rate (GFR), serum N-terminal pro B–type natriuretic peptide (NT-proBNP) and plasma cortisol concentrations, and plasma renin activity. Linear mixed-effects modeling was used to compare changes in variables from baseline (day 1 for the same experiment) among treatment conditions.

RESULTS

Changes in serum glucose concentration and GFR were significantly greater after administration of prednisone at 4 mg/kg than for the control condition. Fractional excretion of sodium was decreased from baseline when dogs received 0.5, 1, or 4 mg of prednisone/kg, compared with results for the control condition. Several expected changes in clinicopathologic values were observed after prednisone administration at any dose. Changes in serum NT-proBNP concentration, plasma renin activity, and SAP did not differ from changes for the control condition at any prednisone dose.

CONCLUSIONS AND CLINICAL RELEVANCE

Oral prednisone administration did not affect SAP, NT-proBNP concentration, or measures of renin-angiotensin-aldosterone system activation in healthy laboratory-housed dogs but was associated with relative increases in GFR and serum glucose concentration.
Finite-time active disturbance rejection control for marine diesel engine

Published: March 2020

In order to handle the non-linear system and the complex disturbance in marine engines, a finite-time convergence active disturbance rejection control (ADRC) technique is developed for the control of engine speed. First, a model for the relationship between engine speed and fuel injection is established on the basis of the mean value engine model. Then, to deal with the load disturbances and model parameter perturbation of the diesel engine, this paper designs an ADRC approach to achieve finite-time stability. Finally, simulation experiments show that the proposed method has better control effect and stronger disturbance rejection ability in comparison with the standard linear ADRC.

Antecedents of loyalty intentions among young adult tourists: a survey
Authors: Wąsowicz-Zaborek Elżbieta
Published: March 2020

The purpose of this paper was to examine the antecedents of young adult tourists’ loyalty intentions. The study is concerned with the overall loyalty tendencies of individuals, comprising the two dimensions of revisit intentions (RVIs) and recommendation intentions (RIs), and thus does not explore their loyalty to a specific destination (as in most previous studies). The research uses an Internet questionnaire with a total sample of 305 university students recruited from two Polish universities. Statistical analysis with the partial least squares structural equation modeling method indicates that destination RI is mainly driven by social bonding, while RVI is influenced positively by risk and uncertainty avoidance and negatively by novelty and variety seeking. In addition, income is found to be a significant moderator in the relationship between risk and uncertainty perception and RIs, such that a transition from very low to very high incomes tends to reverse the focal relationship from positive to negative. In addition, the research demonstrates that there is no significant difference between male and female young tourist’s loyalty intention. Implications for tourism entrepreneurs and destinations are suggested in the concluding section of the article.
The Earning Losses of Smokers
Authors: Bhai Moiz
Published: March 2020

Using within-family variation from twins and siblings, I find that smokers earn approximately 16% less than nonsmokers. Possible explanations for this earning difference are addiction-related productivity declines and earning reductions from higher health insurance costs. To investigate further, I use variation in the provision of employer-supplied health insurance (ESHI) to examine the mechanism of whether the addiction or insurance component has a larger influence on earnings. While I generally observe a larger earning penalty for smokers with ESHI than smokers without ESHI, the earning difference is statistically indistinguishable from zero.
