Speed vs. comfort: Testing the efficacy of a single question for predicting transit users’ route choices
Authors: Simons Joseph John Pyne , Farber Ilya
Published: November 2019

Not all transit users have the same preferences when making route decisions. Understanding the factors driving this heterogeneity enables better tailoring of policies, interventions, and messaging. However, existing methods for assessing these factors require extensive data collection. Here we present an alternative approach - an easily-administered single item measure of overall preference for speed versus comfort. Scores on the self-report item predict decisions in a choice task and account for a proportion of the differences in model parameters between people (n=298). This single item can easily be included on existing travel surveys, and provides an efficient method to both anticipate the choices of users and gain more general insight into their preferences.

Authors: Strobel Alexander , Wieder Gesine , Paulus Philipp C. , Ott Florian , Pannasch Sebastian , Kiebel Stefan J. , Kührt Corinna
Published: November 2019

Individuals tend to avoid cognitive demand, yet, individual differences appear to exist. Recent evidence from two studies suggests that individuals high in the personality traits Self-Control and Need for Cognition that are related to the broader construct Cognitive Effort Investment are less prone to avoid cognitive demand and show less effort discounting. These findings suggest that cost-benefit models of decision-making that integrate the costs due to effort should consider individual differences in the willingness to exert mental effort. However, to date, there are almost no replication attempts of the above findings. For the present conceptual replication, we concentrated on the avoidance of cognitive demand and used a longitudinal design and latent state-trait modeling. This approach enabled us to separate the trait-specific variance in our measures of Cognitive Effort Investment and Demand Avoidance that is due to stable, individual differences from the variance that is due to the measurement occasion, the methods used, and measurement error. Doing so allowed us to test the assumption that self-reported Cognitive Effort Investment is related to behavioral Demand Avoidance more directly by relating their trait-like features to each other. In a sample of N = 217 participants, we observed both self-reported Cognitive Effort Investment and behavioral Demand Avoidance to exhibit considerable portions of trait variance. However, these trait variances were not significantly related to each other. Thus, our results call into question previous findings of a relationship between self-reported effort investment and demand avoidance. We suggest that novel paradigms are needed to emulate real-world effortful situations and enable better mapping between self-reported measures and behavioral markers of the willingness to exert cognitive effort.

Published: November 2019

The objectives of this study were to describe the Myers-Briggs Type Indicator (MBTI) distribution of Ontario Veterinary College (OVC) veterinary students ( n = 1,249), and to evaluate its associations with gender and career interests. This was achieved by collecting pre-matriculation data from 11 graduating classes. Overall, OVC veterinary students were diverse in their MBTI types and preferences, as well as career interests. Extraversion, Sensing, Thinking, and Judging were the most prevalent preferences. Female veterinary students were 2.96 (95% CI = 2.11–4.17) times more likely to demonstrate the Feeling preference and 1.89 (95% CI = 1.41–2.56) more likely to prefer Judging, compared to male students (who were more likely to prefer the Thinking and Perceiving preferences, respectively). At entry to the veterinary program, students who preferred Intuition (vs. Sensing) were 2.08 (95% CI = 1.33–3.33) times more likely to be interested in a veterinary career other than practice, and 1.92 (95% CI = 1.43–2.56) times more likely to be undecided about their future veterinary career path. Both at entry to the program and in their final-year stream choice, students of the Thinking preference were more likely to select equine or food animal, rather than small animal practice, compared to students of the Feeling preference. There were additional significant associations regarding MBTI preferences and career interests. This study highlights the diversity of veterinary students, and provides an opportunity for educators to potentially expand their teaching methods and career guidance resources to better reach students of all MBTI preferences.

Authors: Lane India F. , Sims Michael , Howell Nancy E. , Bailey Misty
Published: November 2019

On the basis of strategic initiatives and an evolving focus on educational program enhancement, faculty and staff members designed a structured program to provide leadership and resources for improving instruction and disseminating educational scholarship in a veterinary college. The University of Tennessee College of Veterinary Medicine Master Teacher Program was conceptualized in the teaching academy model as a forum for professional development and dialogue. A small leadership team worked with other faculty to develop the program proposal, including its mission, vision, values, and initial goals. Programming includes monthly meetings to discuss a range of policy, theoretical, and practical topics, as well as periodic workshops focused on current strategic initiatives or hot topics. Ten years later, the program continues to successfully connect educators and have an impact on the college and profession. Attendance has grown steadily; feedback has been positive. Participants rate the program’s overall value highly, particularly its impact on their teaching, the opportunity to stay current in educational topics, and the opportunity to learn from colleagues. Discussions within the program have provided valuable input for college policy and practices. Keys to sustained success have included a historical culture emphasizing the teaching mission, alignment with college goals, consistency in leadership and programming, periodic revisions and rebranding, and attention to new faculty and staff needs. This article describes the development, growth, and perceived impact of the program and emphasizes lessons learned and actions taken to sustain its success without additional personnel and at minimal cost.

Published: November 2019

There has been rapid growth in the range of models available for teaching veterinary clinical skills. To promote further uptake, particularly in lower-income settings and for students to practice at home, factors to consider include cost, availability of materials and ease of construction of the model. Two models were developed to teach suturing: a silicon skin pad, and a tea towel (with a check pattern) folded and stapled to represent an incision. The models were reviewed by seven veterinarians, all of whom considered both suitable for teaching, with silicon rated as more realistic. The learning outcome of each model was compared after students trained to perform a simple interrupted suture. Thirty-two second-year veterinary students with no prior suturing experience were randomly assigned to three training groups: silicon skin pad or tea towel (both self-directed with an instruction booklet), or watching a video. Following training, all students undertook an Objective Structured Clinical Examination (OSCE), placing a simple interrupted suture in piglet cadaver skin. The OSCE pass rates of the three groups were silicon skin pad, 10/11; tea towel, 9/10; and video, 1/11. There was no significant difference between the model groups, but the model groups were significantly different from the video group ( p < .017). In conclusion, the tea towel was as effective as the silicon skin pad, but it was cheaper, simpler to make, and the materials were more readily available. In addition, both models were used effectively with an instruction booklet illustrating the value of self-directed learning to complement taught classes.

Published: November 2019

The veterinary profession continually strives to address wellness issues such as compassion fatigue, burnout, stress, anxiety, and depression. Wellness issues may begin during the professional curriculum when students experience intense academic, clinical, social, and personal demands on their time. The purpose of this article was to assess the use of progressive muscle relaxation (PMR) as a simple, non-invasive stress reduction technique for first-year veterinary students ( n = 101) at a US veterinary college. Students completed a 38-item questionnaire, the Smith Relaxation States Inventory 3 (SRSI3), both before and after performing PMR. Scores for the categories of basic relaxation, mindfulness, positive energy, transcendence, and stress were assessed. Female students ( n = 92) had significant ( p < .05) improvement in basic relaxation, mindfulness, and stress after completing PMR. Male students ( n = 9) had significant ( p < .05) improvement in basic relaxation and stress after completing PMR. When grouped according to age, all students had significant ( p < .05) improvement in the categories of basic relaxation and stress. Students in the 22-year-old ( n = 31), 23-year-old ( n = 29), 24-year-old ( n = 15), and 25-year-old or greater ( n = 17) groups also had significant improvement ( p < .05) in mindfulness. Additionally, students in the 23-year-old group had significant ( p < .05) improvement in positive energy. These results support the use of PMR as a potential self-care strategy for students to implement during their academic and professional careers.

Published: November 2019

Veterinary students may pursue extracurricular surgical experiences before performing ovariohysterectomy or orchidectomy in their veterinary curriculum. We sought to evaluate the impact of these experiences on student confidence and subsequent surgical performance during students’ first canine ovariohysterectomy or orchidectomy during their veterinary school curriculum. We enrolled 69 third-year veterinary students to complete pre- and post-operative surveys reporting their confidence to perform surgery and self-assessing their performance. Students had all completed five semesters of surgical skills training on models and cadavers but varied in their participation in extracurricular surgical experiences. A subset of students ( n = 27) were digitally recorded while performing ovariohysterectomy (16) or orchidectomy (11). Digital recordings were scored by a blinded rater using task-specific rubrics and a global rating scale, and time to perform the procedure was recorded. The number of extracurricular surgeries students had performed was positively correlated with their confidence to perform orchidectomy ( r = .78) but not ovariohysterectomy ( r = −.17). There was no correlation between extracurricular surgeries performed and subsequent rubric scores or surgical times for the first ovariohysterectomy ( r = −.01 and r = −.14, respectively) or orchidectomy ( r = .09 and r = −.18, respectively) performed as part of their veterinary curriculum. Our results suggest that extracurricular surgical experiences may not impart a long-term improvement on performance scores or surgical time during students’ first surgery of their veterinary curriculum. Additional research is necessary to clarify how model training and extracurricular surgical experiences on live animals interact to affect students’ subsequent surgical performance.
Effect of Neural Mobilization on Nerve-Related Neck and Arm Pain: A Randomized Controlled Trial
Authors: Basson Cato Annalie , Stewart Aimee , Mudzi Witness , Musenge Eustasius
Published: November 2019

Purpose: Neural mobilization (NM) is often used to treat nerve-related conditions, and its use is reasonable with nerve-related neck and arm pain (NNAP). The aims of this study were to establish the effect of NM on the pain, function, and quality of life (QOL) of patients with NNAP and to establish whether high catastrophizing and neuropathic pain influence treatment outcomes. Method: A randomized controlled trial compared a usual-care (UC; n = 26) group, who received cervical and thoracic mobilization, exercises, and advice, with an intervention (UCNM; n = 60) group, who received the same treatment but with the addition of NM. Soft tissue mobilization along the tract of the nerve was used as the NM technique. The primary outcomes were pain intensity (rated on the Numerical Pain Rating Scale), function (Patient-Specific Functional Scale), and QOL (EuroQol-5D) at 3 weeks, 6 weeks, 6 months, and 12 months. The secondary outcomes were the presence of neuropathic pain (using the Neuropathic Diagnostic Questionnaire) and catastrophizing (Pain Catastrophising Scale). Results: Both groups improved in terms of pain, function, and QOL over the 12-month period ( p < 0.05). No between-groups differences were found at 12 months, but the UCNM group had significantly less pain at 6 months ( p = 0.03). Patients who still presented with neuropathic pain ( p < 0.001) and high pain catastrophizing ( p = 0.02) at 6- and 12-mo follow-ups had more pain. Conclusions: Both groups had similar improvements in function and QOL at 12-month follow-up. The UCNM group had significantly less pain at 6-month follow-up and a lower mean pain rating at 12-month follow-up, although the difference between groups was not significant. Neuropathic pain is common among this population and, where it persisted, patients had more pain and functional limitations at 12-mo follow-up.

Authors: Bessette Jennifer , Généreux Mélissa , Thomas Aliki , Camden Chantal
Published: November 2019

Purpose: Advocacy is an essential component of physiotherapy (PT) practice. As a result, universities are expected to teach and assess advocacy-related competencies in their curriculum. The purpose of this study was to explore current educational practices for teaching and assessing advocacy in Canadian PT programmes, barriers to teaching and assessment, and solutions for enhancing educational practices. Method: We used a convergent parallel mixed-methods design. Teachers and coordinators from Canadian PT programmes completed an online survey, and clinical supervisors participated in telephone interviews. We performed descriptive statistics and thematic analyses. Results: Advocacy-related competencies were widely covered in the academic curriculum of the 13 PT programmes represented by our participants, but not all competencies were assessed equally. Barriers to teaching and assessment of advocacy included the lack of role clarity, relevant teaching and assessment strategies, time, and opportunity to practice the role in the curriculum. Students’ personal experience and motivation also had an impact. Conclusion: Essential steps toward enhancing educational practices are to clarify the definition of advocacy, guide PT educators in explicitly and concretely teaching and assessing advocacy, develop a staged approach to covering advocacy throughout the curriculum, and normalize advocacy as a PT domain.
Dependence of Surface Tension on Surface Concentration in Ionic Surfactant Solutions and Influences of Supporting Electrolyte Therein
Authors: Wang Chuangye , Liu Feng , Yang Hongxia , Morgner Harald , Zhang Longli , Lin Xufeng , Liu Zhen , Fu Hui
Published: November 2019

It has been well-known that the addition of electrolytes causes the ionic surfactant solution to have a lower surface tension by stimulating the surface adsorption. When the surface concentration of an ionic surfactant remains constant, the solution with supporting electrolyte in the bulk displays a lower surface tension than a solution without electrolyte. From the surface perspective we investigate the dependence of the surface tension of a solution upon the surface concentration of ionic surfactant and the influences of the supporting electrolyte therein, by means of thermodynamics and molecular dynamics simulation. The derived thermodynamic formula and simulation results predict, that at a given surface concentration the supporting electrolyte can change the orientation of the ionic surfactant, which results in a lower surface tension. The conclusions can be useful for the investigation to the surface structure of ionic surfactant solutions and the effects of supporting electrolyte.
Dynamic Surface Properties of Eco-Friendly Cationic Saccharide Surfactants at the Water/Air Interface
Authors: Zhi Lifei , Li Xiaoming , Wang Hui , Xue Yongbin , Zhang Qinghua , Wang Xiangjun
Published: November 2019

The equilibrium surface properties and dynamic surface tension (DST) are presented for aqueous solutions of novel eco-friendly cationic saccharide surfactants (CnDGPB) at different concentrations and temperatures. The equilibrium surface tension, the DST, the effective diffusion coefficients and the activation barrier of the surfactants are calculated and analyzed. In addition, the general diffusion mechanism of the surfactants is proposed. The equilibrium surface tension results show that the γCMC and CMC values decrease with increasing temperature. The interactions (repulsion forces) between the hydrophobic groups and water molecules decrease with increasing temperature, which results in increased HLB values. This phenomenon causes a higher Amin and lower Γmax. The DST of CnDGPB below and above the CMC is tested by the maximum bubble pressure method at temperature from 25 °C to 45 °C. The adsorption activation energy of CnDGPB is between 3 kJ/mol and 20 kJ/mol. The results show that the final stages of the DST decays are consistent with the activated diffusion-controlled adsorption mechanism.
Solubilization and Thermodynamic Attributes of Nickel Phenanthroline Complex in Micellar Media of Sodium 2-Ethyl Hexyl Sulfate and Sodium Bis(2-ethyl hexyl) Sulfosuccinate
Authors: Noor Sadia , Rashid Muhammad Abid
Published: November 2019

Micellar solubilization and physicochemical behaviour of [Ni(phen)3]F2 EtOH · MeOH · 8 H2O complex in sodium 2-ethylhexyl sulfate and sodium bis(2-ethyl hexyl) sulfosuccinate is addressed in this paper. The interactions of surfactants in the solution of nickel complex were studied by UV-Vis spectroscopy and electrical conductivity. The extent of solubilization in terms of partitioning and binding parameters was determined by UV-Vis spectroscopy, whereas conductivity data were employed to calculate critical micellar concentration and other thermodynamic parameters of micellization. The value of critical micellar concentration increased in both surfactants due to structure breaking effect of nickel complex. The complex showed significant antioxidant radical scavenging and hemolytic activities, without any substantial cytotoxic activity against 3T3 cell line.
Exploring Breastfeeding Knowledge and Attitudes among Noncaregivers: A Narrative Review
Authors: Chan Kathleen , Whitfield Kyly C.
Published: November 2019

Exclusive breastfeeding to 6 months with continued breastfeeding up to 2 years and beyond are well-established infant feeding recommendations based on evidence that breastfeeding has unparalleled maternal and infant health benefits as well as environmental and economic benefits. As with many high-income countries, breastfeeding rates remain suboptimal with only a quarter of Canadian and European infants receiving breast milk exclusively for the first 6 months. Breastfeeding promotion efforts have largely targeted caregivers in the prenatal and postnatal period; however, breastfeeding outcomes have been shown to be associated with broader sociocultural factors. Noncaregivers play an influential role in infant feeding at both an individual level (e.g., cues and input from health care practitioners and caregivers’ social networks; as future parents) as well as a broader population level (sociocultural norms and policy decisions). This paper outlines recent research on breastfeeding knowledge and attitudes of noncaregivers by population subgroup. Positive correlations have been identified between breastfeeding attitudes, infant feeding knowledge, breastfeeding exposure, and breastfeeding intention among different subgroups; however, key knowledge gaps, lack of exposure to breastfeeding, and negative public perceptions of breastfeeding persist. Dietitians can advocate for breastfeeding promotion strategies that consider the role of noncaregivers to address sociocultural norms around breastfeeding.
Weight Inclusive Practice: Shifting the Focus from Weight to Social Justice
Authors: Bessey Meredith , Lordly Daphne
Published: November 2019

Obesity is framed by mainstream media and health care professionals as an “epidemic” contributing to the ill health of the population. This paper reviews literature related to dominant discourses about weight in dietetics, drawing on literature from other health care disciplines, and how these discourses influence patient care. Emerging, competing discourses are also reviewed. Literature highlighted that dietitians and dietetic students are often biased and hold stigmatizing beliefs toward “overweight” and “obese” patients. No research has been conducted in Canada addressing this question, leaving this as an opportunity for future research. Weight stigma and interventions focused on weight have multiple negative implications for individuals, especially those living in larger bodies, including reluctance to seek health care, poor body image, subsequent weight gain, and increased disordered eating. There are alternative discourses emerging, which shift the focus away from weight and toward social justice. The ways in which dietetic students are trained to “manage” weight, and how dominant discourses influence this training, is an important area of future exploration. Dietetic professionals are encouraged to reflect on their weight biases and educate themselves on weight inclusive approaches to health, such as Health at Every Size and Well Now.

Published: November 2019

The object of our research is hydrogeochemical conditions of the Mesozoic hydrogeological basin within Yamalo-Nenets oil and gas bearing region. The Mesozoic basin includes the Aptian-Albian-Cenomanian, Neocomian and Jurassic hydrogeological complexes. These complexes contain thermal and mineralized water. The water exchange in the basin in question is significantly hampered; this is reflected in hydrogeochemical conditions. The article presents the distribution maps of water types in three complexes of the Mesozoic basin, maps of changes in the magnitude of mineralization and the content of the most valuable microcomponents (iodine and bromine). It has been established that with the depth (from the Aptian-Albian-Cenomanian to the Jurassic complex) the area of distribution of sodium bicarbonate-type water increases. Further directions of groundwater research in the region are noted.

Authors: Tsidaev В. S. , Golik V. I. , Mayer A. V.
Published: November 2019

Oil production and use have become a priority element in ensuring the existence of human society and one of the main areas of research. Despite the abundance of publications on this topic, there is a gap in the development. Available publications don't contain information about the possibility of obtaining associated goods, which could reduce production costs. The aim of the study is to fill the gap by searching for technology that provides the opportunity to obtain associated marketable products in the form of metals.  The research methodology used to achieve the goal combines the methods of systematizing and analyzing the available data on oil production technology and metal leaching technology with an integrated technology assessment at the expert assessment level.  The results of the study include a proposal for the extraction of metals from oil-bearing rocks by leaching methods. The essence and mechanism of a fundamentally new technology for mining reserves of oil fields by leaching metals from ores during the integration of underground processes of oil pyrolysis and leaching of metals from oil-bearing rocks, combining the possibilities of mine-borehole development and physicochemical leaching processes, are described. The advantages of the new technology are formulated. The obtained results provide an answer to the objectives of the study and indicate the achievement of the goal.

Main gas and oil pipelines are the most important objects of the fuel and energy complex of the state. They are subjected to strict requirements for reliable and safe operation. Therefore, it is necessary to assess their strength (current strength) and durability (prediction strength) when operating main pipelines.  The wall of the pipes of the existing main pipelines is subjected to various loads and influences. To prevent pipeline failure, strength and durability calculations are performed. The parameters of the load and mechanical resistance of the pipes are taken into account when calculating. Therefore, the "load — resistance" model is used to quantify the reliability of the main pipeline. This paper presents the main theoretical provisions of the methodology for assessing the strength and durability of trunk pipelines with single and combined defects in the framework of a combined probabilistic-statistical approach, and also an example of the use of the technique for a section of a trunk pipeline examined by an inline flaw detector.

The article describes the technology for creating a mobile viscoelastic waterproof screen in the well that uncovers an oilwater reservoir. There are three stages with the following ratio of components, mass. %, based on the completion at the boundary of the oilwater contact. The first portion of the composition is 1 % (wt.) uniflock solution + 5 % (wt.) CuSO4. Then the second portion of the composition is pumped in the following ratio of components, mass. %: 1 % (wt.) uniflock solution + 10 % (wt.) CuSO4 + ETS-32 (volume ratio ETS-32:CuSO4 = 0,33:0,17). At the final stage is the injection of the third portion of the composition in the following ratio of components, mass. %: 2 % (wt.) uniflock solution + 10 % (wt.) CuSO4 + ETS-32 (volume ratio ETS-32:CuSO4 = 0,33:0,17).
The Welfare State and The Market Economy: The Austrian experience as a Social Market Economy (SME)
Authors: Fazeli Rafat , Fazeli Reza
Published: November 2019

This paper concentrates on the recent development of the welfare state and social wage in Austria. Our empirical review is concerned with the net benefits or net social wage received by the Austrian working population. Net social wage is defined as the difference between the social benefits received and taxes paid by the working class. This measurement will enable us to find out whether the working population has received a net gain (or net social wage) and whether this net gain has expanded over time. The paper offers a study of the trends of the “social wage” in France in the last decades before the Great Recession. It addresses two major questions. The first question is whether the expansion of social expenditures has posed any drag on capital accumulation and economic growth in this country. The second question is whether the increasing ideological challenges from the right and the competitive pressures of globalization have led to the retrenchment of the French welfare states in recent decades.
