Predicting Career Search Self-efficacy: The Role of Self-transcendence, Self-consciousness, Self-control and Self-management
Authors: Kabadayı Fedai , Şahin Mustafa
Published: January 2019

The aim of this study is to predict career search self-efficacy. In this context, predictive variables are self-transcendence, self-consciousness and self-control and self-management. The research data obtained from 1278 university students. 786 (61.5%) were girls. Regression analysis and correlation analysis were used. According to the findings, it was determined that self- transcendence, self-control and self-management, social anxiety, appearance consciousness and internal self-awareness were significant predictors of career search self-efficacy. The strongest predictor is the variable self-transcendence. In this context, experimental interventions or psycho-educational programs based on these skills, which are related to the self, can be tested in order to increase career search self-efficacy.

PENGARUH PEMBERIAN DIET TINGGI LEMAK TERHADAP KONSENTRASI SECRETORY IMMUNOGLOBULIN A (sIgA) SALIVA TIKUS PUTIH Rattus norvegicus YANG DIINDUKSI BAKTERI Aggregatibacter actinomycetemcomitans (Aa)
Authors: Kristanti Risma Aprinda
Published: January 2019

Hiperlipidemia menyebabkan perubahan pada sel imun dan proses penyembuhan luka, sehingga juga meningkatkan kemungkinan untuk terserang periodontitis yang terutama disebabkan oleh bakteri Aggregatibacter actinomycetemcomitans (Aa) atau infeksi lainnya. Asam lemak yang berlebihan dapat menghambat proliferasi sel karena hasil peroksidasi lipid yang bersifat toksik bagi sel. Asam lemak juga ikut mempengaruhi produksi dan modulasi sitokin karena asam lemak dapat menyebabkan reduksi proliferasi limfosit. Diet tinggi lemak telah menyebabkan penurunan jumlah limfosit B. Pada perkembangannya, limfosit B membentuk sel B memori dan sel plasma yang memproduksi antibodi, termasuk IgA. Penelitian ini bertujuan untuk mengetahui pengaruh pemberian diet tinggi lemak dan induksi bakteri Aa terhadap konsentrasi secretory Immunoglobulin A (sIgA) saliva. Sebanyak 28 tikus Rattus norvegicus Strain Wistar dibagi dalam empat kelompok secara random, kelompok K0 diberi pakan standar, kelompok K1 diberi pakan standar kemudian diinduksi bakteri Aa, kelompok K2 diberikan diet tinggi lemak, dan kelompok K3 diberikan diet tinggi lemak kemudian diinduksi bakteri Aa. Pada akhir penelitian seluruh tikus diambil cairan saliva dan diukur konsentrasi sIgA saliva menggunakan metode ELISA. Dari hasil penelitian menunjukkan bahwa terdapat perbedaan yang signifikan konsentrasi sIgA saliva antara kelompok pakan standar tanpa induksi bakteri Aa (K0) dengan kelompok diet tinggi lemak tanpa induksi bakteri Aa (K2) dan antara kelompok pakan standar dengan induksi bakteri Aa (K1) dengan kelompok diet tinggi lemak dengan induksi bakteri Aa (K3)

 
Wasatiyyah Islam in The Framework Pesantren Education Tradition
Authors: Hasan Mohammad
Published: January 2019

Islamic boarding schools are religious institutions that not only teach religious problems to santri, but also relate to the role of porndok pesantren on community empowerment. Islamic boarding schools also have a role in national politics. In this context the role of the pesantren in dialogue and contextualizing Islamic teachings is not rigid and black and white. But Islamic boarding schools are able to display the teachings of Islam that are harmonious, peaceful, tolerant, and not radical. Islamic understanding initiated by Islamic boarding schools is far from the values of radical doctrines, or easy doctrine to state ‘heresy’ to other groups. This becomes the view and value championed by the pesantren community including the role of the Kiai (Islamic clergy) in developing modern and global life.
Poder y violencia sexual contra las mujeres: modelos de hegemonía y didáctica en las Historias de Polibio
Authors: Moreno Leoni Álvaro M.
Published: January 2019

Este artículo trata sobre la violencia sexual contra las mujeres en las Historias de Polibio. Los estudios modernos acerca del tema son escasos y no han abordado esta cuestión. Aunque las mujeres no desempeñaron un papel central en los hechos narrados en la obra, algunos pasajes parecen relacionar la violación de mujeres con reflexiones políticas y didácticas concretas. Aquí, se argumenta que Polibio exploró conscientemente las consecuencias de la degradación de las alianzas entre estados y su transformación de la igualdad al gobierno tiránico mediante el uso de una metáfora sexual explícita. En ese sentido, se estudian los ejemplos de Filipo V de Macedonia, los cartagineses en Iberia y Escipión Africano.
LINGUISTIC WORLDVIEW REPRESENTATION IN THE ETHNOLINGUISTIC TEXTS (on materials of Tambov Region)
Authors: Andreeva Olga Nikolaevna
Published: January 2019

We consider objective and conceptual representation sides of linguistic worldview in the ethnolinguistic texts. Language as the main channel of information transmission, as an informative sign equivalent of being, is intended primarily to transfer the meanings of culture, to describe its space. Verbalization of the cultural phenomena essence is inseparable from attempts to build a linguistic worldview, which comes from the ontological, so called “general” worldview. Language worldview accumulates spiritual and material components of a culture and is most clearly manifested in ethnolinguistic texts, the so called “cultural texts” – about rites, ritual acts, rituals, calendar holidays, etc. Rite, ritual, calendar holiday is a kind of action, the embodiment of the spiritual basis of existence is a sacred action of men on earth to translate spiritual ideas. On the example of the prayer for rain recorded by us in the Tambov Region, we analyze the semantic and semiotic components of the ritual text, show the material and spiritual components of the transfer of the meanings of this phenomenon of culture. We describe the action side of the prayer for rain from the lexical and semantic constants of the objective side of the language worldview. The analysis of the spiritual part of this rite is from the conceptual side of the language worldview.

The historical and political prototypes are the material for the creation of bright and memorable images in the novel by M.A. Bulgakov “Fatal eggs” are described: A.S. Rokk (chief commander of the Workers' And Peasants' Red Army S.S. Kamenev), Polaitis (Marshal M.N. Tukhachevsky), Shchukin (A.I. Egorov), “red-moustached driver” (a talented scientist-inventor, engineer of III rank P.K. Oshchepkov). We determine theatrical and genre sources that influenced the creation of images: mystery, farce, buffo, pantomime. The text satirical and grotesque nature the is investigated. In the framework of the farce and buffo the First Moscow process where the prototypes are is considered. The composition and genre issues are touched upon, the problem of attribution of the story is raised. To the source base of the work are added: occult novel by A. Crowley “Moonchild”, stories by A. Schnitzler “Rock”, U. Allen “Fatal Experience”, R. Market “Invention of Professor Carter”, R. Presber “Last Feast of the Last of Birkovich”, B. Lavrenev “The Child Gregory”. References to the iconic systems of the Egyptian “Book of the Dead” and the collection of Arab fairy tales “One Thousand and One Nights” are used.

MIMO PID Controller Tuning Method for Quadrotor Based on LQR/LQG Theory
Authors: Guardeño Rafael , López Manuel J. , Sánchez Víctor M.
Published: January 2019

In this work a new pre-tuning multivariable PID controllers method for quadrotors is put forward. A procedure based on LQR/LQG theory is proposed for attitude and altitude control. With the aim of analyzing performance and robustness of the proposed method, a non-linear mathematical model of the DJI-F450 quadrotor is employed, where rotors dynamics, togheter with sensors drift/bias properties and noise characteristics of low-cost comercial sensors typically used in this type of applications (such as MARG with MEMS technology and LIDAR) are considered. In order to estimate the state vector and compensate bias/drift effects on rate gyros of the MARG, a combination of filtering and data fusion algorithms (Kalman filter and Madgwick algorithm for attitude estimation) are proposed and implemented. Performance and robutsness analysis of the control system is carried out by means of numerical simulations, which take into account the presence of uncertainty in the plant model and external disturbances. The obtained results show that the proposed pre-tuning method for multivariable PID controller is robust with respect to: a) parametric uncertainty in the plant model, b) disturbances acting at the plant input, c) sensors measurement and estimation errors.
Evolution of Sustainability in Alternative Food Networks: A Systematic Literature Review
Authors: Michel-Villarreal Rosario , Hingley Martin , Canavari Maurizio , Bregoli Ilenia
Published: January 2019

In recent years, increasing attention has been paid to individuals organizing themselves and managing food systems in an ‘alternative’ and more sustainable way. Such emerging food initiatives are most commonly known as ‘Alternative Food Networks’ (AFNs). However, there is an ongoing debate concerning the extent to which AFNs facilitate social, economic and environmental change. There are criticisms of the overall sustainability promise of AFNs related to sufficiency of impact, possible countereffects and relevance of impacts. Because often empirical studies only focus on specific sustainability issues or AFNs, it has been difficult to develop more robust theories about the relation between diverse AFNs arrangements and sustainability. Thus, the aim of this paper is to contribute towards reducing this knowledge gap through a systematic literature review on AFNs in relation to sustainability. We summarise main methodological approaches, types of AFNs studied and sustainability dimensions addressed in literature to date. Findings serve as reference to propose opportunities for future research regarding sustainability in AFNs.
Automodified Poly(ADP-Ribose) Polymerase Analysis to monitor DNA Damage in Peripheral Lymphocytes of Floricoltorists occupationally exposed to Pesticides
Authors: Imperato Serena , Mistretta Carmela , Marone Maria , Migliaccio Ilaria , Pulcinelli Ilaria , Faraone Mennella Maria Rosaria
Published: January 2019

Background: Increased DNA damage and the propension to cancer development, depend on the modulation of the mechanisms to control and maintain genomic integrity. Poly(ADP-Ribose)Polymerase activation and automodification are early responses to genotoxic stress. Upon binding to DNA strand breaks, the enzyme, a molecular DNA nick sensor, is hyperactivated: this is the first step in a series of events leading to either DNA repair or apoptosis. Enzyme hyperactivation and automodification can be easily measured and are widely used to look at DNA damage extent in the cell. We investigated whether these two markers (increased catalytic activity and auto modification), could help to monitor DNA damage in lymphocytes of flower growers from Southern Italy, occupationally exposed to pesticides. Methods: Peripheral lymphocyte lysates were analysed for Poly(ADP-Ribose) Polymerase activity, and by SDS-PAGE and anti-Poly(ADP-Ribose)Polymerase 1-antibody to measure automodified anti-Poly(ADP-Ribose) Polymerase levels by densitometry. Results: Poly(ADP-Ribose)Polymerase activity levels were consistent with those of enzyme auto-modification. Growers daily exposed to pesticides, showed both biomarkers very high, either in the presence or in the absence of pathologies. Conclusions: PARP activity and auto-modification in peripheral blood lymphocytes are possible,non-invasive, and routinar tools to monitor the healthy conditions of floricoltorists.

The central Hokkaido, Northern Japan, was struck by an earthquake of M6.7 on September 6, 2018. Its deep hypocenter of 37 km might result of a complex crust and upper mantle structure in Hidaka arc-arc collision system. A seismic intensity of 7 on the Japan Meteorological Agency (JMA) scale was observed at Atsuma Town. About 90% of the casualties were due to the multiple earthquake-induced landslides in Atsuma Town, and a significant number of houses in the urban areas of Sapporo were damaged due to soil liquefaction. Destruction of electric power facilities near the epicenter caused a long-term power outage in approximately 2,950,000 houses in Hokkaido. The widespread blackout caused secondary damages to utilities, civil life, and economic activities in the region. The number of refugees from this incident was approximately 13,111 in maximum, and the economic damage also increased further as a result of the electric blackout. The Hokkaido Prefectural Government immediately applied the Disaster Relief Act on that accrual day. On September 28, 2018, the National Government certified the event as the Designated Disaster of Extreme Severity.
The spin Drude weight of the XXZ chain and generalized hydrodynamics
Authors: Urichuk Andrew , Oez Yahya , Klümper Andreas , Sirker Jesko
Published: January 2019

Based on a generalized free energy we derive exact thermodynamic
Bethe ansatz formulas for the expectation value of the spin current, the
spin current-charge, charge-charge correlators, and consequently the
Drude weight. These formulas agree with recent conjectures within the
generalized hydrodynamics formalism. They follow, however, directly from
a proper treatment of the operator expression of the spin current. The
result for the Drude weight is identical to the one obtained 20 years
ago based on the Kohn formula and TBA. We numerically evaluate the Drude
weight for anisotropies \Delta=\cos(\gamma)Δ=cos(γ)
with \gamma = \pi n/mγ=πn/m,
n\leq mn≤m
integer and coprime. We prove, furthermore, that the high-temperature
asymptotics for general \gamma=\pi n/mγ=πn/m—obtained
by analysis of the quantum transfer matrix eigenvalues—agrees with the
bound which has been obtained by the construction of quasi-local
charges.
SOVYETLER BİRLİĞİ’NİN AFGANİSTAN’I İŞGALİ VE TÜRKLER
Authors: ERMAN Kubilayhan
Published: January 2019

Afganistan’da 1979 ve 1989 yılları arasında devam eden Sovyet işgali Soğuk Savaş’ın son büyük silahlı çatışmasına yol açmıştır. “Savr Devrimi” olarak adlandırılan 1978 hükümet darbesinin Sovyet yanlısı yönetimine karşı başlayan münferit ve örgütsüz ayaklanmalar Sovyet Ordusu’nun Afganistan’a girmesiyle üçüncü tarafların desteklediği geniş kapsamlı bir direniş mücadelesine dönüşmüştür. Krizin asıl aktörleri Sovyetler Birliği ve Marksist Afgan Hükümeti ile bunların karşısındaki direnişçilerdir. Afganistan topraklarındaki direniş grupları, Pakistan ya da İran’da yerleşik dinî nitelikli siyasi partilerin şemsiyesi altında faaliyet gösterirlerken aynı zamanda ABD, Pakistan ve Suudi Arabistan gibi ülkelerden finansal yardım ve silah desteği alıyorlardı. Bu siyasi partiler söylemlerinde yoğun olarak İslami temaları kullanmalarına rağmen aslında etnik temel ve arka planda oluşmuşlardı. Genel olarak Afganistan’daki halkın bir kısmı etnik yakınlık duydukları siyasi partilerin himayesindeki direnişçi gruplara katılmışlar, bazıları ise Sovyet yanlısı hükümet tarafında olmayı tercih etmişlerdir. Çoğunlukla Kuzey Afganistan’da yerleşik Türkler de diğer etnik gruplarda olduğu gibi aynı yolu izlemişler, Kâbil hükümetini desteklemeyi ya da Sovyet askerî güçlerine karşı koymayı seçmişlerdir. Afganistan harekâtına katılan Türk kökenli Sovyet vatandaşları da göz önüne alındığında bu coğrafyadaki Türklerin silahlı çatışmanın farklı taraflarında savaşmak zorunda kaldığı olgusu ile karşılaşılır. Bu çalışmada, Sovyet işgali ve sonrasındaki yakın dönemde Afganistan’daki ve Sovyet ordusunda görev alan Türklerin durumu ve faaliyetleri öne çıkan Türk kökenli şahsiyetler çerçevesinde incelenmiştir.
Mobile crowd participation to root small-scale piped water supply systems in India and Bangladesh

Published: January 2019

In the arsenic-contaminated Ganges-Brahmaputra-Meghna Delta in India and Bangladesh, small-scale piped water supply seems a promising way to provide safe drinking water to households in the region. The use of smartphone applications can support monitoring of the system and enhance local engagement and empowerment. In this paper the scope for mobile crowd participation as a research and monitoring tool for piped water supply systems in Bihar, India and in Khulna and Chittagong, Bangladesh is investigated. In these areas, the use of smartphones and internet access are growing rapidly and smartphone applications would enable real-time water quality monitoring, payment of water bills, awareness creation, and a dialogue between the end-user and the water supplier. To identify the relevance and acceptability of piped water supply and smartphone monitoring, four surveys with potential end-users were conducted. Based on these surveys we conclude that in the investigated areas there is a desire for piped water systems, that households already own smartphones with internet access, and that there is an interest in smartphone monitoring. The enabling environment to deploy mobile crowd participation for piped water system monitoring stimulates further research towards an investigation of potential functionalities and the actual development of such an application.

Published: January 2019

Water, sanitation and hygiene (WASH) are vital indicators to healthy living and safe environments for child development. The aim of the study was to determine WASH status and practices in ECD centres located in low socio-economic areas of Nelson Mandela Bay during 2017. This cross-sectional study elicited responses from 46 ECD centres which had a total of 3,254 children and 172 caregivers. A structured questionnaire and visual observation were used. Using core WASH in schools' indicators (WinS) showed that despite improved water sources being available in 91% of the facilities, WinS for hygiene was poor. The study observed that 57% of the respondents had improved toilets accommodating both genders. In 29% of ECD centres, 6–10 children make use of a ‘pottie’ while in 9% of the cases, more than 20 children make use of one ‘pottie’. The use of the bucket system was noted in 22% of the ECD centres. In 79% of the ECD centres, children wash their hands in a communal plastic bowl. Only 11% of the study population washed hands hygienically under a running tap or tippy tap. WASH conditions in the ECD centres in the study area require urgent attention and further investigation for practical solutions.

The increase of CO2 in the atmosphere may produce some effects on drinking water because water tends to naturally capture CO2 species. The main purpose was the study of the impact of capture of free CO2 and its transformation to carbonic acid (H2CO3) and bicarbonate ions (HCO−3). The study used a Tillmans equilibrium diagram obtained from the modified Mojmir Mach model as a function of water temperature and considered the effects on anion and cation composition. Three wells located in different zones were selected, with similar characteristics (capture of CO2). Samples were taken in different seasons of the year and the amount of CO2 in the drinking water was calculated. It was found that with increasing concentrations of free CO2 the pH decreases, and this process makes the water acid and susceptible to dissolve some elements (Ca, Na, K, Si) and other species (HCO−3). The capture of CO2 has important effects on the anion and cation composition of drinking water and on the variation of pH by more than one unit, which may affect the health of consumers. The method presented in this study is an excellent user-friendly alternative to determine the impact of natural capture of total CO2 by water.

Published: January 2019

An investigation of the utilization of water quality monitors at water purification plants throughout Japan was conducted via questionnaire from August to October 2015. The number of types of monitors installed at more than one water purification plant was 34. Chlorine, high sensitivity turbidity, pH, and turbidity monitors were (highly) recommended for installation in four water purification processes (rapid sand filtration, chlorination only, slow sand filtration and membrane treatment), except for high sensitivity turbidity of chlorination only. The number of installations of the monitors recommended and their installation points were dependent upon the processes. Highly recommended points of turbidity were raw water and sedimentation points, which were set for (critical) control points in water safety plans. That of high sensitivity turbidity was the rapid sand filtration point for confirmation of Cryptosporidium control. Chlorine monitors were applied for automatic control, regardless of the water purification processes. Some interesting monitors, such as those for musty odor compounds and trihalomethane, were newly developed and utilized. The results of this study showed that water quality monitors were important for water quality management systems based on water safety plans in Japan.
Numerical Solution of the Stefan's Problem
Authors: Borodin Stanislav
Published: January 2019

All of the most well-known numerical methods for solving the Stefan’s problem, as well as a new method developed by the author are considered for the purpose of choosing the most efficient of them from a perspective of accuracy and computational speed. A comparison is carried out on the results of solving the problem for the boundary motion of “ice-water” phase transition around the vertical well passing through the thickness of permafrost. The conclusions, which are distributed to other multidimensional and multi-front statements of the Stefan’s problem, are made. The mathematical model, the brief description of the considered numerical methods and the boundaries of their applicability are presented. The comparison shows the advantages and disadvantages of different methods. It is demonstrated that the use of the explicit scheme leads to a marked increase in computation time, the six-point symmetric scheme may have oscillating solution; therefore, the implicit scheme is the most preferred. It is concluded that the most efficient method for one-dimensional and one front Stefan’s problems is the method of catching the front in the grid node using the implicit scheme, and the most efficient method for multi-dimensional and multi-front Stefan’s problems is the enthalpy method using the implicit scheme, which has been developed by the author.
Comparative Retrospective Analysis of Accuracy of Robotic-Guided versus Fluoroscopy-Guided Percutaneous Pedicle Screw Placement in Adults with Degenerative Spine Disease
Authors: Faissal Zahrawi , Brian Manzi , Jill Sager
Published: January 2019

Background:

Robotic-guidance for pedicle screws can reportedly increase placement accuracies and surgical efficiencies especially in percutaneous approaches.

Objective:

The study aimed to compare the accuracy of percutaneous pedicle screw placement and post-operative course of robotic-guidance versus fluoroscopy-guidance performed by a surgeon experienced in performing fluoroscopy-guided MIS spinal fusions.

Study Design:

This is a retrospective medical chart review of 2 cohorts of consecutive patients operated by the same surgeon.

Methods:

Medical records of adults suffering from degenerative spine disease treated by percutaneous spinal fusion surgeries with robotic-guidancevs. fluoroscopy-guidance were reviewed. Endpoints included pedicle screw placement accuracy (on post-operative CTs) and surgical complications and revisions.

Results:

Ninety-nine patients were reviewed in each arm which were similar in demographics and surgical indications. The robotic arm had 5.8 screws per case on average and 6.0 in the control arm (p=0.65). No significant differences were found in postoperative complication rates revision surgeries length of stay duration of surgery screw implantation times blood loss or results of Oswestry Disability Index questionnaires.

Post-operative CTs were available for 52 patients (293 screws) in the robotic arm and 70 (421 screws) in the freehand controls. In the robotic arm 100% of screws were found accurately placed within the “safe zone”vs. 410 screws (97.4%) in the control arm (p=0.005). Of 11 breaching screws in the control arm one breached by 6mm but the patient did not suffer from any sequelae (12-month follow-up). The average follow up period was 9.2±4 months in the robotic-guided arm and 10.5±3 in the control arm. There were no significant differences in complications or revisions.

Conclusion:

A modest yet statistically significant increase in pedicle screw placement accuracy was observed with robotic-guidance compared to freehand. Larger prospective studies are needed to demonstrate differences in clinical outcomes.

Published: January 2019

This paper adds to the evidence base in the discussion to what extent woodland development can be a means to restoring the land affected by mining. We investigate the formation of vegetation communities in sites on a former Sulphur quarry in the Roztochya district of the Lviv region in Ukraine to answer the research questions: How can the formation of vegetation cover affect the disturbed sites and what knowledge can be used in restoration practices elsewhere? We perform an experiment examining which types of vegetation are suitable for the restoration. We explore the influence of restored vegetation and re-emerged woodlands have on the process of soil rehabilitation and the increasing organic substance in it. We examine the impact of various combinations of vegetation on land rehabilitation. Explaining the degree of colonization of waste land by various types of vegetation helps us to reveal the trends of regenerative processes and identify the most promising for restoration tree species in affiliation with the ground vegetation. The results can assist decision-makers in choosing compatibility alliances of vegetation to sustain regeneration processes. Although this research is location specific, the knowledge developed can to a degree be applied to similar places, in the temperate zone.

Authors: Novikov Arthur I. , Ivetić Vladan
Published: January 2019

The seed of Pinus sylvestris L. originating from natural forest in Voronezh region, Russian Federation, was graded in four classes based on seed diameter size, using the operational equipment of screens with round openings. The ungraded seedlot was used as control. Seedlings were produced in Voronezh containerized forest nursery, from March to September 2015, following the standard procedure for Pinus sylvestris. Seed from each size class, plus control, is sown in containers with 120 cm3 cells, filled with peat-substrate, grown in greenhouse for eight weeks, followed by hardening in growing area until the end of the growing season. The results shows a week positive effect of seed grading on height of one-year old container-grown seedlings, but significant improvement of seed use efficiency by reducing the number of empty cells. Based on results of this study, we can recommend grading of Pinus sylvestris seed on two size classes.

BACKGROUND

Cardiorespiratory fitness (CRF), an important index of physical fitness, is the ability to inhale and provide oxygen to the exercising muscle. However, despite its importance, the current gold standard for measuring CRF is impractical, requiring maximal exercise from the participants.

OBJECTIVE

This study aimed to develop a convenient and practical estimation model for CRF using data collected from daily life with a wristwatch-type device.

METHODS

A total of 191 subjects, aged 20 to 65 years, participated in this study. Maximal oxygen uptake (VO2 max), a standard measure of CRF, was measured with a maximal exercise test. Heart rate (HR) and physical activity data were collected using a commercial wristwatch-type fitness tracker (Fitbit; Fitbit Charge; Fitbit) for 3 consecutive days. Maximal activity energy expenditure (aEEmax) and slope between HR and physical activity were calculated using a linear regression. A VO2 max estimation model was built using multiple linear regression with data on age, sex, height, percent body fat, aEEmax, and the slope. The result was validated with 2 different cross-validation methods.

RESULTS

aEEmax showed a moderate correlation with VO2 max (r=0.50). The correlation coefficient for the multiple linear regression model was 0.81, and the SE of estimate (SEE) was 3.518 mL/kg/min. The regression model was cross-validated through the predicted residual error sum of square (PRESS). The PRESS correlation coefficient was 0.79, and the PRESS SEE was 3.667 mL/kg/min. The model was further validated by dividing it into different subgroups and calculating the constant error (CE) where a low CE showed that the model does not significantly overestimate or underestimate VO2 max.

CONCLUSIONS

This study proposes a CRF estimation method using data collected by a wristwatch-type fitness tracker without any specific protocol for a wide range of the population.
Web Comparison of Three Contingent Valuation Techniques in Women of Childbearing Age: The Case of Ovulation Induction in Quebec (Preprint)
Authors: Dieng Aissata , He Jie , Poder Thomas G
Published: January 2019

BACKGROUND

In Canada, 11.5% to 15.7% of couples suffer from infertility. Anovulation, or failed ovulation, is one of the main causes of infertility in women. In Quebec, the treatment for ovulation induction and other services related to assisted reproductive technology (ART) have been partially reimbursed by the government since 2010.

OBJECTIVE

This study aimed to compare the willingness to pay (WTP) of women of childbearing age to receive drug treatment in the event of failed ovulation according to 3 different contingent valuation methods.

METHODS

The following elicitation techniques were used: simple bid price dichotomous choice (DC), followed by an open-ended question (DC-OE), and a simplified multiple-bounded discrete choice (MBDC). Each participant was randomly assigned to 1 of 3 elicitation techniques. Bid prices ranged from Can $200 to Can $5000. Of the 7 bid prices, 1 was randomly proposed to each participant in the DC and DC-OE groups. For the DC-OE group, if the answer to the DC bid price was no, respondents were asked what was the maximum amount they were willing to pay. For the MBDC group, each respondent was offered an initial bid price of Can $1500, and the subsequent bid price offer increased or decreased according to the answer provided. “Do not know” responses were considered as a “no”, and each individual was questioned as to their certainty after each choice. WTP values were estimated using probit and bivariate models; the Welsh and Poe model was also performed for the MBDC group.

RESULTS

The survey was conducted from 2009 to 2010 with a total sample of 680 women. Analyses were performed on 610 respondents (199 DC, 230 DC-OE, and 181 MBDC). Of the 70 respondents who were excluded, 6 did not meet the age criterion, 45 had an annual income less than Can $2500, and 19 did not respond to the WTP question. Mean WTP values were Can $4033.26, Can $1857.90, and Can $1630.63 for DC, DC-OE, and MBDC, respectively. The WTP for MBDC “definitely yes” and “probably yes” values were Can $1516.73 and Can $1871.22, respectively. The 3 elicitation techniques provided WTP value differences that were statistically significant (P<.01). The MBDC was the most accurate method, with a lower confidence interval (Can $557) and a lower (CI/mean) ratio (0.34).

CONCLUSIONS

A positive WTP for ovulation induction was found in Quebec. Adding a follow-up question resulted in more accurate WTP values. The MBDC technique provided a more accurate estimate of the WTP with a smaller and, therefore, more efficient confidence interval. To help decision making and improve the effectiveness of the fiscal policy related to the ART program, the WTP value elicited with the MBDC technique should be used.
