Unconventional incentive schemes in tourism enterprises, does it make sense?
Authors: Kozłowski Maciej 
Published: August 2019

Abstract
The purpose of this article is to describe the model of the most important employee financial participation (EFP) programs and give some proposals aiming at wider promotion of financial participation in tourist companies in order to show the occurring relations between the programs applied and the socioeconomic results of enterprises. The research has been based on available literature and own research conducted on the sample of Polish companies listed on Warsaw Stock Exchange. The author’s research could serve as a guide to carry out similar research in the tourist resort. Financial participation programs existing in particular countries differ because of various circumstances in which they are applied, various range and eligibility of employees, though it is possible to find such elements which they have in common. What can be expected is a radical change in workers’ attitudes towards a higher commitment, stronger identification with the company, and as a result taking responsibility for its future. It is even more important in tourist industry (in transnational tourist companies) in a comparison to the traditional one. It can be assumed that the awareness aspect plays here a vital role in the way to a success of the whole company and individual employees’ as well. Unfortunately, this is not a common condition. We can expect that EFP programs generally would have a positive influence on the functioning of the tourist enterprise. However, the effects could be rather social than economic. More rigorous statistical analysis is needed to know more about economic results in tourist industry, unfortunately such studies are not conducted in tourism, so the question in the title is still open.
Advancement in the Pressureless Sintering of CP Titanium Using High-Frequency Induction Heating

Published: August 2019

Abstract
High-frequency induction heating is applied as an alternative heating source for pressureless sintering of commercially pure Ti powders, aiming to intensify the sintering process. The effects of the process parameters on the properties of the sintered material are systematically studied. The initial powder compact density is the most influential parameter permitting sintered structures with highly porous to almost fully dense appearance. Short heating time combined with sintering to temperatures just above the β-transus resulted in a strong diffusion bonding between the Ti powder particles, and grain growth is observed at the former boundaries of the neighboring powder particles. The dimpled appearance of the fracture surface at those regions confirmed the strong metallic interparticle bonding. Tensile properties comparable to those of Ti-Grade 3 and Ti-Grade 4 are achieved, which also demonstrates the efficiency of the induction sintering process. A mechanism explaining the fast and efficient sintering is proposed. The process has the added advantage of minimizing the oxygen pickup.

Abstract
Even after controlling for stage, comorbidity, age, and insurance status, black women with breast cancer (BC) in the USA have the lowest 5-year survival as compared with all other races for stage-matched disease. One potential cause of this survival difference is the disparity in cancer treatment, evident in many population clinical trials. Specifically, during BC chemotherapy, black women receive less relative dose intensity with more dose reductions and early chemotherapy cessation compared with white women. Symptom incidence, cancer-related distress, and ineffective communication, including the disparity in patient-centeredness of care surrounding patient symptom reporting and clinician assessment, are important factors contributing to racial disparity in dose reduction and early therapy termination. We present an evidence-based overview and an explanatory model for racial disparity in the symptom experience during BC chemotherapy that may lead to a reduction in dose intensity and a subsequent disparity in outcomes. This explanatory model, the Symptom Experience, Management, Outcomes and Adherence according to Race and Social determinants + Genomics Epigenomics and Metabolomics (SEMOARS + GEM), considers essential factors such as social determinants of health, clinician communication, symptoms and symptom management, genomics, epigenomics, and pharmacologic metabolism as contributory factors.

Published: August 2019

AbstractIntroductionWe develop a framework to model disease progression across Alzheimer's disease (AD) and to assess the cost‐effectiveness of future disease‐modifying therapies (DMTs) for people with mild cognitive impairment (MCI) due to AD.MethodsUsing data from the US National Alzheimer's Coordinating Center, we apply survival analysis to estimate transition from predementia to AD dementia and ordered probit regression to estimate transitions across AD dementia stages. We investigate the cost‐effectiveness of a hypothetical treatment scenario for people in MCI due to AD.ResultsWe present an open‐access model‐based decision‐analytic framework. Assuming a modest DMT treatment effect in MCI, we predict extended life expectancy and a reduction in time with AD dementia.DiscussionAny future DMT for AD is expected to pose significant economic challenges across all health‐care systems, and decision‐analytic modeling will be required to assess costs and outcomes. Further developments are needed to inform these health policy considerations.
Genital Pain and Numbness and Female Sexual Dysfunction in Adult Bicyclists

Published: August 2019

ABSTRACT

Introduction
Bicycle seat pressure on the perineum may impair arousal and clitoral erection, likely contributing to genital pain and numbness experienced by female cyclists.

Aim
We aimed to identify the association between genital pain and numbness experienced by female cyclists and female sexual dysfunction (FSD).

Methods
Female cyclists were recruited to complete an online survey using the Female Sexual Function Index (FSFI), a validated questionnaire to assess FSD. Cyclist demographics, experience, preferred riding style, use of ergonomic cycle modifications, and genital discomfort while riding were also queried. Multivariate logistic regression analysis was used to evaluate risk factors of FSD.

Main Outcome Measures
The main outcome was FSFI score, which is used to diagnose FSD when the FSFI score is &lt;26.55.

Results
Of the survey respondents, 178 (53.1%) completed the survey and FSFI questionnaire. Mean age was 48.1 years (±0.8 standard error [SE]), and the average riding experience was 17.1 years (±0.9 SE). Overall, 53.9% of female cyclists had FSD, 58.1% reported genital numbness, and 69.1% reported genital pain. After adjusting for age, body mass index, relationship status, smoking history, comorbidities, and average time spent cycling per week, females who reported experiencing genital numbness half the time or more were more likely to have FSD (adjusted odds ratio [aOR], 6.0; 95% CI, 1.5–23.6; P = .01), especially if localized to the clitoris (aOR, 2.5; 95% CI, 1.2–5.5; P = .02). Females that reported genital pain half the time or more while cycling also were more likely to have FSD (aOR, 3.6; 95% CI, 1.2–11.1; P = .02). Cyclists experiencing genital pain within the first hour of their ride were more likely to have FSD (aOR, 12.6; 95% CI, 2.5–63.1; P = .002). Frequency and duration of cycling were not associated with FSD. Analysis of FSFI domains found that the frequency of numbness was correlated with decreased arousal, orgasm, and satisfaction during intercourse, whereas the frequency of pain significantly reduced arousal, orgasm, and genital lubrication.

Clinical Implications
Female cyclists that experience numbness and/or pain have higher odds of reporting FSD.

Strengths & Limitations
Our study includes a validated questionnaire to assess FSD and queries specific characteristics and symptoms of genital pain and genital numbness; however, the study is limited by its cross-sectional survey design.

Conclusion
This study highlights the need for cyclists to address genital pain and numbness experienced while cycling, and future studies are required to determine if alleviating these symptoms can reduce the impact of cycling on female sexual function.
Familial Intracranial Aneurysm in Newfoundland: Clinical and Genetic Analysis
Authors: Powell Amy E. , Fernandez Bridget A. , Maroun Falah , Noble Barbara , Woods Michael O. 
Published: August 2019

ABSTRACT:Objective:Intracranial aneurysm (IA) is an expansion of the weakened arterial wall that is often asymptomatic until rupture, resulting in subarachnoid hemorrhage. Here we describe the high prevalence of familial IA in a cohort of Newfoundland ancestry. We began to investigate the genetic etiology of IA in affected family members, as the inheritance of this disease is poorly understood.Methods:Whole exome sequencing was completed for a cohort of 12 affected individuals from two multiplex families with a strong family history of IA. A filtering strategy was implemented to identify rare, shared variants. Filtered variants were prioritized based on validation by Sanger sequencing and segregation within the families.Results:In family R1352, six variants passed filtering; while in family R1256, 68 variants remained, so further filtering was pursued. Following validation by Sanger sequencing, top candidates were investigated in a set of population controls, namely,C4orf6c.A1G (p.M1V) andSPDYE4c.C103T (p.P35S). Neither was detected in 100 Newfoundland control samples.Conclusion:Rare and potentially deleterious variants were identified in both families, though incomplete segregation was identified for all filtered variants. Alternate methods of variant prioritization and broader considerations regarding the interplay of genetic and environmental factors are necessary in future studies of this disease.

Published: August 2019

ABSTRACTObjective:To describe social participation strategies and resilience in the people affected by the 2017 earthquakes in Mexico.Methods:A cross-sectional study was carried out with 1504 participants from Mexico City, State of Mexico, Oaxaca, Chiapas, Puebla, and Morelos in November and December 2017. A nonprobabilistic convenience sampling method was used to recruit voluntary participants who met the inclusion criteria: age 18 or over and residents in damaged states at the time of the earthquakes. Postearthquake social participation strategies were assessed with the formats used in the postearthquake Chilean survey in 2010. The Spanish-validated version of the resilience scale RS-14 was applied for measuring resilience in the Mexican population.Results:The most frequent social participation strategies were related to emotional support and aid supplying water, food, and clothing. The highest resilience was observed in the state of Oaxaca and in Mexico City. Men, people age 40 or over, and people who defined themselves as indigenous were the most resilient.Conclusions:Factors related to resilience were male gender, age over 40, did not participate in activities of help to the community, no household damage, and belonging to an indigenous community.
Nonlocal Effect on the Pull-in Instability Analysis of Graphene Sheet Nanobeam Actuator
Authors: Lin M. X. , Lee S. Y. , Chen C. K. 
Published: August 2019

ABSTRACTIn this study, the pull-in phenomenon of a Nano-actuator is investigated employing a nonlocal Bernoulli-Euler beam model with clamped-clamped conditions. The model accounts for viscous damping, residual stresses, the van der Waals (vdW) force and electrostatic forces with nonlocal effects. The hybrid differential transformation/finite difference method (HDTFDM) is used to analyze the nonlocal effects on a graphene sheet nanobeam, which is electrostatically actuated under the influence of the coupling effect, the von Kármán nonlinear strains and the fringing field effect. The pull-in voltage as calculated by the presented model deviates by no more than 0.29% from previous literature, verifying the validity of the HDTFDM. Furthermore, the nonlocal nonlinear behavior of the electrostatically actuated nanobeam is investigated, and the effects of viscous damping, residual stresses, and length-gap ratio are examined in detail. Overall, the results reveal that small scale effects significantly influence the characteristics of the graphene sheet nanobeam actuator.
Lamb Waves in Anisotropic Functionally Graded Plates: A Closed Form Dispersion Solution
Authors: Kuznetsov S. V. 
Published: August 2019

ABSTRACTPropagation of harmonic Lamb waves in plates made of functionally graded materials (FGM) with transverse inhomogeneity is studied by combination of the Cauchy six-dimensional formalism and matrix exponential mapping. For arbitrary transverse inhomogeneity a closed form implicit solution for dispersion equation is derived and analyzed. Both the dispersion equation and the corresponding solution resemble ones obtained for stratified media. The dispersion equation and the corresponding solution are applicable to media with arbitrary elastic (monoclinic) anisotropy.
Soret- Dufour Effect on Mixed Convection Past a Vertical Plate in Non-Darcy Porous Medium Saturated With Buongiorno Nanofluid in the Presence of Thermal Dispersion
Authors: Aghbari A. , Ali Agha H. , Sadaoui D. 
Published: August 2019

ABSTRACTNumerical analysis was investigated for steady two-dimensional double diffusive mixed convection boundary layer flow over a semi-infinite vertical plate embedded non-Darcy porous medium filled with nanofluid, in presence of thermal dispersion and under convective boundary conditions. The Buongiorno nanofluid model is used, while the porous medium is described by the Darcy-Forchheimer extension. The governing partial differential equations are transformed into four coupled nonlinear ordinary differential equations using an appropriate similarity transformations and the resulting system of equations is then solved numerically by the finite-difference method. Numerical results are presented to illustrate how the physical parameters affect the flow field, temperature, concentration and solid volume fraction profiles. In addition, the variation of heat, mass and nanoparticle transfer rates at the plate are exhibited graphically for different values of pertinent parameters.
Does behavioural inhibition system dysfunction contribute to Attention Deficit Hyperactivity Disorder?
Authors: Sadeghi S. , McIntosh J. , Shadli S. M. , Healey D. , Rostami R. , Trani P. , McNaughton N. 
Published: August 2019

AbstractThe Reinforcement Sensitivity Theory of Personality has as its main foundation a Behavioural Inhibition System (BIS), defined by anxiolytic drugs, in which high trait sensitivity should lead to internalising, anxiety, disorders. Conversely, it has been suggested that low BIS sensitivity would be a characteristic of externalising disorders. BIS output should lead to increased arousal and attention as well as behavioural inhibition. Here, therefore, we tested whether an externalising disorder, Attention Deficit Hyperactivity Disorder (ADHD), involves low BIS sensitivity. Goal-Conflict-Specific Rhythmicity (GCSR) in an auditory Stop Signal Task is a right frontal EEG biomarker of BIS function. We assessed children diagnosed with ADHD-I (inattentive) or ADHD-C (combined) and healthy control groups for GCSR in: a) an initial smaller study in Dunedin, New Zealand (population ~120,000: 15 control, 10 ADHD-I, 10 ADHD-C); and b) a main larger one in Tehran, Iran (population ~9 [city]-16 [metropolis] million: 27 control, 18 ADHD-I, 21 ADHD-C). GCSR was clear in controls (particularly at 6–7 Hz) and in ADHD-C (particularly at 8–9 Hz) but was reduced in ADHD-I. Reduced attention and arousal in ADHD-I could be due, in part, to BIS dysfunction. However, hyperactivity and impulsivity in ADHD-C are unlikely to reflect reduced BIS activity. Increased GCSR frequency in ADHD-C may be due to increased input to the BIS. BIS dysfunction may contribute to some aspects of ADHD (and potentially other externalising disorders) and to some differences between the ADHD subtypes but other prefrontal systems (and, e.g. dopamine) are also important.
Vulture declines, threats and conservation: the attitude of the indigenous Ghanaian

Published: August 2019

SummaryUnderstanding the attitude of people towards vultures, especially factors that influence behaviours that support their conservation, is crucial if the decline in vultures is to be slowed and reversed. Their vital ecosystem function in keeping the environment free of carcasses and reducing the spread of disease is not yet appreciated in Ghana. Little is known about the attitude of Ghanaians’ about vultures. Structured questionnaires and key informant surveys were employed with a sample size of 460 respondents randomly selected across Ghana. Over 85% of respondents were familiar with the Hooded Vulture Necrosyrtes monachus and vultures were culturally important to 56% of respondents. Diseases that affect livestock are claimed to be treated with chemicals such as diclofenac sodium to which vultures are highly susceptible globally and livestock carcasses were not available to vultures as 53% of respondents bury carcasses. A new poisoning pathway has emerged in which furadan is used to poison wildlife for bushmeat and the offal removed which is then consumed by vultures, as indicated by 78% of respondents. The majority of respondents positively thought vultures were important and must be protected. Poisoning, habitat loss particularly the loss of silk cotton tree Ceiba pentandra and trade in vulture parts for traditional medicine are major threats to vultures in Ghana. Continuous awareness creation, positive attitude towards the environment, vulture conservation programmes and protection of breeding sites were some urgent conservation actions recommended to ensure the survival of vultures.
Single transistor low phase noise active dielectric resonator oscillator

Published: August 2019

AbstractIn this paper, the design theory of an 8 GHz oscillator with a new structure of active dielectric resonator (DR) is presented. The new structure emphasizes on phase noise reduction by using only one active device. The proposed structure uses additional feedback from transistor to resonator in order to increase the quality factor. Measurement results report that phase noise is reduced to −145.19 dBc/Hz at 100 kHz offset frequency which represents 12 dB improvement compared with oscillators with passive DR. Also, in comparison with conventional active resonator oscillators, noise source of the second amplifier which makes spurious oscillation is removed. The size and power consumption are reduced due to the use of a single transistor. This structure has the lowest phase noise in comparison with other DR oscillators. In order to implement the proposed oscillator, a circuit including amplifier, resonator, coupler, and phase shifter is designed and realized.

AbstractBackground:Childhood obesity is a global issue. Excessive weight gain in early pregnancy is independently associated with obesity in the next generation. Given the uptake of e-health, our primary aim was to pilot the feasibility of an e-health intervention, starting in the first trimester, to promote healthy lifestyle and prevent excess weight gain in early pregnancy. Methods: Women were recruited between 8 and 11 weeks gestation and randomised to the intervention or routine antenatal care. The intervention involved an e-health program providing diet, physical activity and well-being advice over 12 weeks.Results:Women (n = 57, 43.9% overweight/obese) were recruited at 9.38 ± 1.12 (control) and 9.06 ± 1.29 (intervention) weeks’ gestation, mainly from obstetric private practices (81.2%). Retention was 73.7% for the 12-week intervention, 64.9% at birth and 55.8% at 3 months after birth.No difference in gestational weight gain or birth size was detected. Overall treatment effect showed a mean increase in score ranking the perceived confidence of dietary change (1.2 ± 0.46, p = 0.009) and score ranking readiness to exercise (1.21 ± 0.51, p = 0.016) over the intervention. At 3 months, infants weighed less in the intervention group (5405 versus 6193 g, p = 0.008) and had a lower ponderal index (25.5 ± 3.0 versus 28.8 ± 4.0 kg/m3) compared with the control group.Conclusion and Discussion:A lifestyle intervention starting in the first-trimester pregnancy utilising e-health mode of delivery is feasible. Future studies need strategies to target recruitment of participants of lower socio-economic status and ensure maximal blinding. Larger trials (using technology and focused on early pregnancy) are needed to confirm if decreased infant adiposity is maintained.
Implications of Updated Magnetic Anomalies for the Late Cretaceous Tectonic Evolution of Walvis Ridge
Authors: Thoram S. , Sager W. W. , Jokat W. 
Published: August 2019

AbstractIn the South Atlantic, a reorganization of the Mid‐Atlantic Ridge began before anomaly C34n (83.6 Ma) and ended before anomaly C30n (66.4 Ma), complicating tectonics of Rio Grande Rise and older Walvis Ridge (WR), which formed together at the Mid‐Atlantic Ridge. This reorganization is poorly understood because magnetic anomalies C30n‐C34n are poorly defined near WR. We interpreted these anomalies along western WR to improve knowledge of Rio Grande Rise‐WR tectonic development. Anomaly trends indicate that Valdivia Bank has an E‐W age progression, perpendicular to that predicted by hot spot models. Anomaly spacing and width is irregular and anomalous near WR, implying a series of ridge jumps and possibly a microplate between anomalies C34n and C32n. Eastward ridge jumps transferred microplate lithosphere to the South American plate. This study shows that Late Cretaceous tectonic evolution of the Rio Grande Rise‐WR large igneous provinces was more complex than previously understood.
