Quelle richesse dans les nombreux témoignages qui font la substance de ce travail de Chantal Régnier ! Que de tabous sont levés par les propos de merveilleuses personnes très âgées, et pourtant pas toujours aussi disposées à « partir » que l’entourage le croit, ou parfois « voudrait le croire ». Au final rien n’est simple.
Un problème de santé publique de plus en plus préoccupant
Authors: Tisseron Serge
Published: November 2017

Nos enfants auront d’autant plus de chances de s’engager dans une bonne utilisation des outils numériques que nous introduirons ceux-ci dans leur vie au bon moment et de la bonne façon. C’est le but des balises 3-6-9-12 d’y contribuer en fondant une indispensable diététique des écrans. Elles s’appuient sur quatre recommandations importantes à tout âge : limiter les temps d’écran, choisir avec les enfants des programmes de qualité, parler avec eux de ce qu’ils voient et font avec les écrans, et encourager leurs activités de création dès le plus jeune âge. Le combat pour les bébés d’aujourd’hui est un combat pour la société de demain.
L’écran est-il bon ou mauvais pour le jeune enfant ?
Authors: Esseily Rana , Guellai Bahia , Chopin Adrien , Somogyi Eszter
Published: November 2017

Le taux d’exposition des enfants à l’écran augmente et devient de plus en plus précoce. Aujourd’hui, selon plusieurs enquêtes américaines, 90% des enfants de moins de deux ans regardent l’écran pendant en moyenne deux heures par jour, et ce malgré les recommandations contraires de l’Académie Américaine de Pédiatrie et du Ministère de la Santé Français. L’objectif de cette revue est double : (1) comprendre les corrélats et les facteurs démographiques déterminant l’exposition à la télévision et (2) étudier les effets de la télévision sur le développement cognitif du jeune enfant. La littérature scientifique montre que l’effet de l’écran dépend moins de la durée de visionnage hebdomadaire que de l’âge et des contextes dans lesquels les enfants regardent l’écran (accompagnés ou non) ainsi que des contenus regardés (éducatifs ou non). Prises dans leur ensemble, les études montrent que l’exposition aux écrans a un impact négatif sur le développement, particulièrement quand l’exposition concerne des enfants âgés de moins de trois ans.
La violence par excès
Authors: Capart Noémie , Venturini Elisa
Published: November 2017

Cet article vise à interroger la violence inhérente non à la télévision à proprement parler mais à son usage prématuré chez l’enfant de moins de 3 ans. Nous entendrons ici la télévision comme un objet dont l’unicité du mode relationnel l’ancre du côté de la saturation des besoins pulsionnels. Équivalent, dans ce contexte précoce, à un prolongement narcissique de la mère, la télévision ne permet pas d’élaborer le manque nécessaire lié à la séparation, et concourt ainsi à inscrire le moi dans une dimension narcissique de sa maturation.
Les bébés face aux supports numériques
Authors: Berdot-Talmier Laurence
Published: November 2017

La technologie numérique étant omniprésente dans la vie des bébés, cet article retrace l’impact des médias, et tout particulièrement celui de la télévision, sur le développement des tout-petits. Bien que la plupart des experts soulignent l’impact négatif de ce support chez les bébés, certains aspects positifs méritent d’être examinés. En outre, les technologies mobiles et tactiles, en représentant une expérience interactive, se doivent d’être considérées différemment.
Le bébé et la tablette numérique : intérêts et dangers
Authors: Clément Marie-Noëlle , Duris Olivier
Published: November 2017

L’environnement technologique confronte aujourd’hui les enfants de plus en plus tôt aux supports numériques. Les tablettes tactiles sont considérées par différents auteurs comme les outils numériques prolongeant le mieux le rapport au monde du bébé. Dans ce contexte, un état des lieux des études portant sur ce sujet, un questionnement sur les effets possibles de ces usages précoces, et la précision de recommandations bordant ces usages nous paraissent importants.
Quand l’échographie fait écho aux hommes
Authors: Perelman Olga
Published: November 2017

Face à l’échographie obstétricale qui donne accès à l’intérieur du corps de la femme, qu’engage cette technique d’imagerie médicale comme vécu de la grossesse par le père qui y assiste ? Nous verrons ce qu’il en est de quelques enjeux psychiques déployés durant la grossesse et au sein de la situation échographique chez des hommes devenant pères pour la première fois. Cet examen si particulier est un axe riche pour saisir les reviviscences anciennes, notamment du côté des mouvements de rivalité adressés à l’enfant à naître et à la compagne.
An Update on the Relationship Between the Gut Microbiome and Obsessive-Compulsive Disorder
Authors: Turna Jasmine , Patterson Beth , Van Ameringen Michael
Published: November 2017

The gut microbiome, the collection of microbes and their genetic material in the human gastrointestinal tract, has recently become a topic of interest in psychiatry. To date, animal studies have repeatedly shown behavior to be affected by alterations in the gut microbiota. Furthermore, studies in clinical psychiatric populations have also illustrated that microbial dysbiosis may play a role in these conditions, but results have been inconsistent. Given the existing animal and human literature providing evidence for a role of the microbiome in anxiety and depressive disorders, this review explores and develops similar lines of evidence in obsessive-compulsive disorder. Theoretical treatment options targeting the gut microbiome are also discussed.

Age and Early Revision After Primary Total Hip Arthroplasty for Osteoarthritis
Authors: Meyer Zachary , Baca Geneva , Rames Richard , Barrack Robert , Clohisy John , Nam Denis
Published: November 2017

Prior reports have noted an increased risk of early revision among younger patients undergoing total hip arthroplasty (THA) but have been confounded by the inclusion of various diagnoses. The purpose of this study was to assess the revision rate and the time to revision for patients undergoing THA for osteoarthritis based on age. Patients with a diagnosis of osteoarthritis who underwent both primary and revision THA at the same institution were identified. The time between primary and revision surgery and the indication for revision were collected. Patients were stratified into 2 groups based on age at the time of primary THA: 64 years or younger (group 1) or 65 years or older (group 2). Between 1996 and 2016, a total of 4662 patients (5543 hips) underwent primary THA for a diagnosis of osteoarthritis. Of these, 100 patients (104 hips) received a revision THA (62 in group 1 and 42 in group 2). Mean age was 52.7±8.4 years in group 1 vs 73.4±6.3 years in group 2 (
P
<.001). There was no significant difference in mean body mass index (29.7±7.3 kg/m
2
vs 28.4±4.6 kg/m
2
,
P
=.30). Rate of revision was not significantly different between the groups (1.8% vs 2.0%,
P
=.7). Average time from primary to revision surgery was 3.0±3.2 years for group 1 and 1.1±2.1 years for group 2 (
P
=.001). Among patients undergoing primary THA for a diagnosis of osteoarthritis, younger age is not associated with an increased rate of early failure or revision. [

For the Love of the Game: Game- Versus Lecture-Based Learning With Generation Z Patients
Authors: Adamson Mary A. , Chen Hengyi , Kackley Russell , Micheal Alicia
Published: November 2017

The current study evaluated adolescent patients' enjoyment of and knowledge gained from game-based learning compared with an interactive lecture format on the topic of mood disorders. It was hypothesized that game-based learning would be statistically more effective than a lecture in knowledge acquisition and satisfaction scores. A pre–post design was implemented in which a convenience sample of 160 adolescent patients were randomized to either a lecture (
n
= 80) or game-based (
n
= 80) group. Both groups completed a pretest/posttest and satisfaction survey. Results showed that both groups had significant improvement in knowledge from pretest compared to posttest. Game-based learning was statistically more effective than the interactive lecture in knowledge achievement and satisfaction scores. This finding supports the contention that game-based learning is an active technique that may be used with patient education. [

In Vivo Measurement of Longitudinal Chromatic Aberration in Patients Implanted With Trifocal Diffractive Intraocular Lenses
Authors: Vinas Maria , Gonzalez-Ramos Ana , Dorronsoro Carlos , Akondi Vyas , Garzon Nuria , Poyales Francisco , Marcos Susana
Published: November 2017

PURPOSE:

To measure the longitudinal chromatic aberration (LCA) by both psychophysical methods and in vivo double-pass retinal imaging in patients bilaterally implanted with trifocal diffractive intraocular lenses (IOLs).

METHODS:

Measurements were performed with a polychromatic adaptive optics system provided with a supercontinuum laser, a Hartmann-Shack wavefront sensor, a deformable mirror, a motorized Badal system, a pupil monitoring system, a double-pass retinal imaging channel, and a psychophysical channel with monochromatically illuminated stimuli. Ten patients (20 eyes) bilaterally implanted with hydrophilic trifocal diffractive IOLs (POD F [FINeVision]; PhysIOL, Liege, Belgium) participated in the study. Measurements were performed in both eyes at three different viewing distances (0.00, +1.75, and +3.50 diopters [D]). Subjective best focus of monochromatic stimuli at five wavelengths (480 to 700 nm) was obtained using the Badal system. Best focused images of through-focus double-pass image series were obtained at three wavelengths (480 to 700 nm). LCA was computed from chromatic difference of focus curves (objective and subjective) as the difference between 480 and 700 nm at near, intermediate, and far.

RESULTS:

The average subjective LCA was 0.82 ± 0.05 D for far, 0.27 ± 0.15 D for intermediate, and 0.15 ± 0.15 D for near. The average objective LCA was 0.72 ± 0.10 D for far, 0.19 ± 0.15 D for intermediate, and 0.07 ± 0.17 D for near.

CONCLUSIONS:

Objective LCA was lower than subjective LCA, which was in agreement with previous studies on patients with phakic and monofocal IOLs. In vivo measurements of LCA enable understanding of the relative contribution of refractive and diffractive LCA and will eventually optimize IOL designs to improve polychromatic image quality.

Risk Factors for Opaque Bubble Layer in Small Incision Lenticule Extraction (SMILE)
Authors: Li Liuyang , Schallhorn Julie M. , Ma Jiaonan , Zhang Lin , Dou Rui , Wang Yan
Published: November 2017

PURPOSE:

To assess the independent effect of myopia and astigmatism on the risk of the occurrence of opaque bubble layer (OBL) in small incision lenticule extraction (SMILE) and further investigate the relationship between scanning depth and OBL.

METHODS:

Twenty-two cases and 317 controls were included in a case–control study from the database of Tianjin Eye Hospital from April 2015 to July 2016. Baseline characteristics were recorded and all of the eyes were manually reviewed by two different observers masked to preoperative refractive status. Multiple regression analysis was used to assess the independent relationship between the attempted correction in diopters and the risk of OBL and to further analyze the association between scanning depth and the risk.

RESULTS:

The risk of OBL significantly decreased with increasing myopia (diopters) (odds ratio [OR] = 0.44; 95% confidence interval [CI]: 0.30 to 0.64;
P
< .0001). The risk of OBL also significantly decreased with increasing astigmatism (diopters) (OR = 0.10; 95% CI: 0.02 to 0.42;
P
= .0017). Lenticular thickness changed by 14.86
μ
m per diopter for myopia (β =14.86; 95% CI = 14.56 to 15.15;
P
< .0001) and 15.10
μ
m per diopter for astigmatism (β = 15.10; 95% CI = 13.96 to 16.24;
P
< .0001), respectively.

CONCLUSIONS:

A low correction was a significant independent risk factor for OBL during SMILE and the effect of astigmatism on OBL was greater than that of myopia. Deepening the photodisruption plane appropriately may reduce the risk of OBL.

Assessing the Likely Effect of Posterior Corneal Curvature on Toric IOL Calculation for IOLs of 2.50 D or Greater Cylinder Power
Authors: LaHood Benjamin R. , Goggin Michael , Esterman Adrian
Published: November 2017

PURPOSE:

To establish whether average refractive overcorrection or undercorrection of corneal astigmatism based on the orientation (rule) of the astigmatism occurs if toric intraocular lenses (IOLs) are calculated on the basis of anterior corneal measurements in eyes requiring toric IOL cylinder power of 2.50 diopters (D) or greater.

METHODS:

One hundred thirteen consecutive eyes with anterior corneal keratometric astigmatism requiring IOL cylinder power of 2.50 D or greater underwent phacoemulsification with IOL powers calculated using anterior corneal curvature data alone. Eyes were grouped as either “with-the-rule” (WTR) or “against-the-rule” (ATR) on the basis of the steep anterior corneal meridian. Targeted and achieved astigmatic outcomes were compared. The main outcome measure was the postoperative refractive astigmatic prediction error.

RESULTS:

A mean overcorrection occurred in anterior WTR eyes of 0.16 ± 0.57 D and a mean undercorrection of ATR eyes of −0.14 ± 0.53 D. These were significantly different from the ideal value of zero (WTR:
P
= .04, ATR:
P
= .05). Although statistically significant, the effect sizes of these prediction errors were 0.40 for WTR and 0.36 for ATR and the error values fell below a clinically significant value of 0.25 D.

CONCLUSIONS:

In eyes requiring toric IOLs of cylinder power 2.50 D or greater, an overcorrection occurs in anterior WTR eyes and an undercorrection in ATR eyes. This probable posterior corneal astigmatism effect is not clinically significant. IOL cylinder powers are sufficiently accurately calculated using unadjusted anterior keratometry values in these eyes.

Discrepancy Between Patient Health Literacy Levels and Readability of Patient Education Materials from an Electronic Health Record
Authors: Imoisili Omoye E. , Levinsohn Erik , Pan Cassie , Howell Benjamin A. , Streiter Shoshana , Rosenbaum Julie R.
Published: November 2017

Limited health literacy is associated with worse health outcomes. It is standard practice in many primary care clinics to provide patients with written patient education materials (PEM), which often come directly from an electronic health record (EHR). We compared the health literacy of patients in a primary care residency clinic with EHR PEM readability by grade level. We assessed health literacy using the Rapid Estimate of Adult Literacy in Medicine-Short Form (REALM-SF), and determined grade level readability for the PEM distributed for the five most common clinical diagnoses using the Simple Measure of Gobbledygook (SMOG) and Flesch-Kincaid metrics. Among 175 participants, health literacy was ≥9th grade for 76 patients (43.4%), 7th to 8th grade for 66 patients (37.7%), and ≤6th grade for 30 patients (17.1%). Average standard PEM readability by SMOG was grade 9.2 and easy-to-read PEM readability was grade 6.8. These findings suggest a discrepancy between the health literacy of most patients who were surveyed and standard PEM readability. Despite national guidelines encouraging clinicians to provide PEM at an appropriate reading level, our results indicate that PEM from EHR may not be readable for many patients.

Health Literacy Universal Precautions Are Still a Distant Dream: Analysis of U.S. Data on Health Literate Practices
Authors: Liang Lan , Brach Cindy
Published: November 2017

Background:

Experts have recommended the adoption of health literacy universal precautions, whereby health care providers make all health information easier to understand, confirm everyone's comprehension, and reduce the difficulty of health-related tasks. The U.S. Department of Health and Human Services selected three health literate practices to track progress in the adoption of health literacy universal precautions.

Objectives:

This study sought to examine whether there has been an increase in the delivery of health literate care and whether recommendations for health literacy universal precautions are being followed.

Methods:

This study used trend and multiple regression analyses of data from 2011 to 2014 from the Medical Expenditure Panel Survey, a national household survey.

Key Results:

The proportion of adults in the U.S. who reported receiving health literate care increased from 2011 to 2014, but fell far short of health literacy universal precautions recommendations of delivering health literate care to everyone. In 2014, 70% of the population reported their providers always gave them instructions that were easy to understand, but only 29% were asked to Teach-Back the instructions and only 17% were offered help with forms. Older, less educated, and racial and ethnic minority group members were more likely to report receiving health literate care than more advantaged groups. People who perceived their health and mental health as fair or poor were less likely to report receiving health literate care.

Conclusions:

Failure to adopt health literacy universal precautions in the face of the high prevalence of limited health literacy in the general population may perpetuate adverse health outcomes that are costly to society. Greater efforts should be made to increase providers' health literacy skills, particularly those who serve populations that are more likely to have limited health literacy, including those with poor health.

[
Health Literacy Research and Practice
. 2017;1(4):e216–e230.]

Plain Language Summary:

This study shows that some health care providers did not always check that their instructions were clear enough for patients to understand. Even fewer providers always offered help in filling out forms. People who were older, less educated, or members of racial or ethnic minority groups were more likely to be asked to confirm their understanding or be offered help with forms. More patients said that their provider was easy to understand, checked their understanding, or offered help with forms in 2014 than in 2011.
Technology Access Gap for Postsecondary Education
Authors: Brown Victoria
Published: November 2017

Technology to learn the digital literacy skills required to attend postsecondary institutions or to access distance learning courses. Three groups of students are impacted by the lack of access to technology: (a) without broadband access, (b) students' low socioeconomic status, and (c) students' primary language is not English. Without digital literacy skills, selecting, applying, and fully participating in a postsecondary education is difficult. This chapter will outline the challenges these three groups of students have in accessing broadband, the impact the lack of access created in Florida, and solutions that were suggested to address lack of high speed broadband.

Authors: Seifert Tami
Published: November 2017

The use of Web 2.0 environments and social media in teaching and learning facilitates the provision of participatory and creative, learner-oriented teaching. The proposed chapter describes the role of social media in teaching and learning in colleges of higher education and suggests possible uses and applications for a variety of social media environments in education, especially the environments of Facebook, Twitter, WhatsApp, and Instagram. Social networks facilitate activities that promote involvement, collaboration and engagement. Modeling of best practices using social networks enhances its usage by students, increases student confidence as to its implementation and creates a paradigm shift to a more personalized, participatory and collaborative learning and a more positive attitude towards its implementation.

Authors: Çıtak Levent , Akel Veli , Ersoy Ersan
Published: November 2017

This study investigates the reaction of investors to the announcement of firms included in BIST Sustainability Index. Stock returns of BIST 50 firms, which are also constituents of BIST Sustainability Index, with those of BIST 50 firms that could not qualify for inclusion in BIST Sustainability Index, are compared. Based on mean/median tests, no significant difference between various returns of two groups of firms is found. Except for interval 0 to +4 days, the findings of event study indicates no significant abnormal returns for BIST Sustainability Index Constituents in the event window of 10 days surrounding the announcement day, but indicates significant positive cumulative abnormal returns for intervals 0 to +4 days, 0 to +5 days, 0 to +7 days, 0 to +8 days, 0 to +9 days and 0 to +10 days, which is an indication that investors valued the BIST Sustainability Index Constituents a few days after the announcement by investing in the stocks of these firms.
Ethics and Corporate Social Responsibility
Authors: Abuznaid Samir Ahmad
Published: November 2017

“…Science will continue to surprise us with what it discovers and creates; then it will astound us by devising new methods to surprise us. At the core of science's self-modification is technology. New tools enable new structures of knowledge and new ways of discovery” (Kelly, 2014). How important is it for organizations to be socially responsible and ethical? This chapter will define ethics and corporate social responsibility (CSR), explain the competitive advantage of creating and maintaining an ethical organization, and discuss the role played by organizations and managers in enhancing ethics and corporate social responsibility. The main focus will be on Palestine Telecommunication Company's (PalTel Group) CSR program and its impact on Palestinian people and organizations. The chapter will conclude by shedding light on major opportunities and challenges facing PalTel Group and its CSR program. Background information is provided, as well as a literature review regarding ethics and corporate social responsibility within Palestine and Palestine Telecommunication Group. A brief discussion of a rival of CSRat PalTel's, Wataniya, has been made in order to ensure that the scope of the chapter's content is complete. The chapter, however, does not examine (employee treatment) nor PalTel Group's ethics policies and their impact on employees and their particular work attitudes. Further, the chapter does not explore how PalTel determines where to invest the resources in social and environmental programs to benefit the community and enhance business performance profitability and reputation. Nor does it measure the impact of CSR practices on competitive advantages, reputation and customer satisfaction. Green washing is common phenomenon in Palestine where almost all businesses claim to be scoring high in the social responsibility parameter. Apart from its academic contribution this chapter may also assist managers and senior officers in strategizing for their organizations in this age of social responsibility.
Workplace Spirituality and Transformational Leadership
Authors: Mack Celeste , Udechukwu Ike , Mujtaba Bahaudin G.
Published: November 2017

Workplace spirituality or spirituality in the workplace is about employees search for meaning, purpose, and interconnectedness in the workplace. Similarly, transformational leadership is a leadership style that encourages a higher level of moral maturity and performance standard for followers. In this chapter, through a review of literature and propositional analysis, the authors demonstrate that transformational leadership has the capacity to drive employees towards meaning, purpose, and interconnectedness with the organization's goals and values. Researchers agree that transformational leadership inspires, motivates, and also attempts to connect with followers. Thus, while workplace spirituality is a potent ingredient in the modern workplace, transformational leadership is the driving force that actually transforms the workplace. Thus, the authors conclude by proposing that transformational leadership can potentially encourage and sustain workplace spirituality. Suggestions and recommendations for future empirical research are provided.
Intended Continued Use Social Networking Sites
Authors: Kock Ned , Moqbel Murad , Barton Kevin , Bartelt Valerie
Published: November 2017

Hedonic information systems are those that are used primarily for pleasure. Previous research has established that the intention to use hedonic information systems is explained mainly by perceived ease of use and perceived enjoyment, with perceived usefulness to one's job being given less importance. Facebook could be seen as a hedonic information system. This paper employs a cross-sectional survey of 178 professionals who used Facebook to various degrees. Predictably, the authors' empirical results show that perceived enjoyment is indeed a much stronger determinant of intended continued Facebook use than ease of use or usefulness to one's job, explaining a considerable proportion of variance in continued use behavior. The authors also find that ease of use is a strong determinant of perceived enjoyment. Interestingly, their results suggest that intended continued Facebook use is significantly and positively associated with job performance, both directly and indirectly via job satisfaction.
The Influence of (Online) Social Networks on Workers' Attitudes and Behaviours in Higher Education Institutions
Authors: Carlos Vera Silva , Rodrigues Ricardo Gouveia
Published: November 2017

According to the literature, social relationships have a positive influence on work-related attitudes and behaviours. Taking into account that Online Social Networks (OSNs), brought about by Web 2.0, have become an international phenomena and have a considerable impact on the way people communicate and interact with each other, the chapter's purpose is to evaluate the effect that the use of OSNs has on the worker's attitudes and behaviours. In this way, the authors use a questionnaire to evaluate the attitudes of 157 faculty members in Higher Education Institutions (HEI). To assess the use of OSNs by faculty members, they use a binary variable. After analysing and discussing the results, the authors conclude that the use of OSNs influences the workers' performance traits. The relations they propose in what concerns the workers' attitudes are all empirically proven. At last, the authors describe the study limitations and suggest some perspectives for future research.
Best Practice in Responding to Critical Incidents and Potentially Traumatic Experience Within an Organisational Setting
Authors: Adamson Carole
Published: November 2017

This chapter addresses best practice for organisational support after critical incidents and traumatic events within social work. Critical incidents are situations and incidents within workplace settings or roles, which, whilst able to be anticipated and planned for, have the potential to create a sense of emergency, crisis, and extreme stress, or have a traumatic impact on those directly or indirectly affected. Alongside the notion of critical incidents are concepts of debriefing, psychological debriefing, critical incident stress debriefing (CISD), and critical incident stress management (CISM). Debate about debriefing models has concerned their effectiveness and safety; the terms being loaded with meaning and tensions between scientific and holistic paradigms and between academic and practitioner perspectives. The chapter suggests areas of research and exploration for agency managers and senior practitioners wishing to make sense of the debates and enables the reader to consider best practice for critical incident response within organisational settings.
Stochastic Processes for the Risk Management
Authors: Özel Gamze
Published: November 2017

The financial markets use stochastic models to represent the seemingly random behavior of assets such as stocks, commodities, relative currency prices such as the price of one currency compared to that of another, such as the price of US Dollar compared to that of the Euro, and interest rates. These models are then used by quantitative analysts to value options on stock prices, bond prices, and on interest rates. This chapter gives an overview of the stochastic models and methods used in financial risk management. Given the random nature of future events on financial markets, the field of stochastic processes obviously plays an important role in quantitative risk management. Random walk, Brownian motion and geometric Brownian motion processes in risk management are explained. Simulations of these processes are provided with some software codes.

Published: November 2017

A shift in water monitoring approach from traditional grab sampling to novel wireless sensors is gaining in popularity not only among researchers but also in the market. These latest technologies readily enable numerous advantageous monitoring arrangements like remote, continuous, real-time, and spatially-dense and broad in coverage measurements, and identification of long-term trends of parameters of interest. Thus, a WSN system is implemented in a river in Kosovo as part of the InWaterSense project to monitor its water quality parameters. It is one of the first state of the art technology demonstration systems of its kind in the domain of water monitoring in developing countries like Kosovo. Water quality datasets are transmitted at pre-programmed intervals from sensing stations deployed in the river to the server at university via the GPRS network. Data is then made available through a portal to different target groups (policy-makers, water experts, and citizens). Moreover, the InWaterSense system behaves intelligently like staying in line with water quality regulatory standards.
Building Communities of Practice Through Faculty Mentorship Programs
Authors: Lari Pooneh , Barton Denise H.
Published: November 2017

Building an effective mentoring program for community college faculty is a complex and multifaceted task. There are multiple layers of stakeholders and levels of involvement, which at times makes navigating the mentoring relationships challenging and complicates the decision of what types of information to provide to the faculty as part of their mentorship. A strategy for developing a successful mentoring program is creating a community of practice among faulty members to provide support, create dialogue, exchange best practices, and hopefully, create a process of collective learning in a community of practice, where faculty are open to receiving guidance and willing to engage in the process as part of the mentoring program with minimal resistance to learning. This article describes the practices and processes of a newly-formed faculty mentoring program at Wake Technical Community College and the aims to add to the body of literature of community college faculty mentoring, vocational training, learning resistance, and faculty development.
A Virtual Supply Chain System for Improved Information Sharing and Decision Making
Authors: Kakhki Mohammad Daneshvar , Nemati Hamid , Hassanzadeh Farhad
Published: November 2017

Integrated supply chain information systems (ISCIS) face various barriers including lack of alignment between IT and business model, security and privacy concerns, behavioral and cultural issues, and heterogeneous software applications. This paper develops an architecture for ISCIS and validate it by interviewing experts. The proposed architecture is an intermediary to integrate in-house information systems as well as cloud-based systems across distributed heterogeneous supply chain networks. The developed ISCIS architecture works in three layers of data, processes, and knowledge and facilitates the alignment of information systems and decision making with business.
Price Discounts and Consumer Load-Shifting Behavior in the Smart Grid
Authors: Al-Ahmadi Eeyad , Erkoc Murat
Published: November 2017

This paper studies the impact of consumers' individual attitudes towards load shifting in electricity consumption in an electricity market that includes a single electricity provider and multiple consumers. A Stackelberg game model is formulated in which the provider uses price discounts over a finite number of periods in order to induce incentives for consumers to shift their peak period loads to off-peak periods. The equilibrium outcomes are investigated and the analytical results are derived for this type of market, where not only the response behaviors of independent consumers are diverse but also an individual consumer's valuation of electricity consumption varies across periods. The obtained results demonstrate that consumer sensitivities to price discounts significantly impact price discounts and load-shifts, which are not necessarily monotonic. The authors also observe that a diverse market leads to lower peak-to-average values and provider payoffs compared to a homogenous market unless the latter one is composed of consumers with relatively lower inconvenience costs during the peak periods.
MaxDiff Choice Probability Estimations on Aggregate and Individual Level
Authors: Lipovetsky Stan
Published: November 2017

This paper considers methods of estimation of choice probability using Maximum Difference (MaxDiff) technique, also known as Best-Worst Scaling (BWS). The paper shows that on the aggregate level the choice probabilities can be obtained using analytical closed-form solution and other approaches such as Thurstone scaling, Bradley-Terry maximum likelihood, and Markov modeling via Chapman-Kolmogorov equations for steady-states probabilities. On the individual level, to account for the exact combinations presented in each task, the Cox hazard model is employed, as well as new approaches of least squares objective for maximum difference, and maximum likelihood in order statistics. The results are useful in the practical MaxDiff applications for items prioritization in marketing research.
Collaborative Calibrated Peer Assessment in Massive Open Online Courses
Authors: Boudria Asma , Lafifi Yacine , Bordjiba Yamina
Published: November 2017

The free nature and open access courses in the Massive Open Online Courses (MOOC) allow the facilities of disseminating information for a large number of participants. However, the “massive” propriety can generate many pedagogical problems, such as the assessment of learners, which is considered as the major difficulty facing in the MOOC. In fact, the immense number of learners who exceeded in some MOOC the hundreds of thousands make the instructors' evaluation of students' production quite impossible. In this work, the authors present a new approach for assessing the learners' production in MOOC. This approach combines the peer assessment with the collaborative learning and the calibrated method. It aims at increasing the degree of trust in peer-assessment. For evaluating the proposed approach, the authors implemented a MOOC dedicated for learning algorithms. In addition, an experiment was conducted during two months for knowing the effects of the proposed approach. The obtained results are presented in this paper. They are judged as very interesting and encouraging.

The resource-based view of the firm from strategic management literature is applied to examine project management as a source of competitive advantage. In this view, assets contribute to competitive advantage if they add economic value, are rare, are difficult to imitate, and have organizational support. This research examines project management assets and project management process outcomes in a cross-industry study that attempts to replicate findings from a prior study, using the same survey tool with a larger sample. Exploratory factor analysis extracted four factors that comprised characteristics of project management assets that are valuable, rare, and inimitable, three factors that comprised of organizational support for project management assets, and two factors that comprised of project management process outcomes. The extracted factors mostly replicated the findings from the prior study; differences emerged in the factors that comprised of project management assets.

Published: November 2017

This paper presents a study of the effects of tool wear on cutting force and surface roughness. The cutting force was measured using a piezoelectric force meter which was attached to the cutting machine's revolving head. The surface roughness was measured after the cutting process was complete using a mechanical touch method. A range of thermoplastic materials and cutting layouts were used to give a broader understanding of the topic. After the measurements were taken, the data were evaluated statistically and the effects of tool wear are illustrated graphically. Furthermore, to understand all of the types of wear which can occur during thermoplastics turning, worn turning inserts taken from industrial machines were examined under a microscope. The aim of the study was to define a method for monitoring tool wear during the turning process to avoid tool breakage and/or reduce the number of scrapped parts.
Motives for Participation in Formal Standardisation Processes for Geographic Information
Authors: Lundsten Jonas , Paasch Jesper Mayntz
Published: November 2017

The purpose of this article is to investigate the personal motives for participation in formal standardization processes for geographic information. The method involved interviewing members of technical committees at the Swedish Standards Institute, SIS. The results are that the majority of the interviewees are very motivated in their work and they think their participation is well-financed by their organizations allocating them to a technical committee. The main motives are to contribute to development of society and be at the forefront of development. However, this article also shows that several members participating in this study felt that they do not have sufficient time for working with tasks related to their technical committees. Their daily work in their respective organizations often has higher priority in relation to standardization work. This contrasts with the organizational goals of the participating organizations and may slow down the development of standards and other publications due to lack of resources.
Achieving Consensus Despite Apposing Stakes

Published: November 2017

Decision-making in many standardization committees is consensus-based, but this can be difficult to achieve if stakeholders have conflicting interests. This article develops an approach to consensus-building in standardization by applying the Harvard method of negotiation to standardization. The authors apply this method in a single case study using action research. The case concerns the first meeting of a national standardization committee aimed at preparing national input for a new ISO standard on sustainable wood. Some stakeholders were in favor of a new standard, others opposed it strongly. Consensus was achieved during the first meeting by adopting the Harvard method and by adding a role play exercise. This outcome is promising for similar standardization cases. Both topic and research method are new in standardization research.

Published: November 2017

AbstractAn unmanned vehicle has been developed for dual use as both an aircraft and a submersible. To achieve long-range emplacement of a highly maneuverable underwater asset to a target environment, the Flimmer (Flying-Swimmer) vehicle is designed for both high-speed flight and low-speed swimming. Building on previous research in bioinspired propulsion and control systems, the vehicle employs a unique set of artificial flapping fins for underwater maneuvering, which must be considered when evaluating the flight and water landing capabilities. This paper describes the computational analysis and experimental results for all three phases of vehicle operation—flight, landing, and swimming. Computational fluid dynamics simulation results predict aero- and hydrodynamic characteristics and demonstrate landing loads on and trajectory of the vehicle. Experimental data demonstrate flight and swimming performance and validate the computational results, and experimental testing of water landing provides a comparison with computations. Results and analyses of the Flimmer vehicle performance demonstrate the operational capabilities of an unmanned hybrid vehicle for long-range flight and low-speed swimming.
Fish Swimming in a Kármán Vortex Street: Kinematics, Sensory Biology and Energetics
Authors: Liao James C. , Akanyeti Otar
Published: November 2017

AbstractFishes often live in environments characterized by complex flows. To study the mechanisms of how fishes interact with unsteady flows, the periodic shedding of vortices behind cylinders has been employed to great effect. In particular, fishes that hold station in a vortex street (i.e., Kármán gaiting) show swimming kinematics that are distinct from their patterns of motion during freestream swimming in uniform flows, although both behaviors can be modeled as an undulatory body wave. Kármán gait kinematics are largely preserved across flow velocities. Larger fish have a shorter body wavelength and slower body wave speed than smaller fish, in contrast to freestream swimming where body wavelength and wave speed increases with size. The opportunity for Kármán gaiting only occurs under specific conditions of flow velocity and depends on the length of the fish; this is reflected in the highest probability of Kármán gaiting at intermediate flow velocities. Fish typically Kármán gait in a region of the cylinder wake where the velocity deficit is about 40% of the nominal flow. The lateral line plays a role in tuning the kinematics of the Kármán gait, since blocking it leads to aberrant kinematics. Vision allows fish to maintain a consistent position relative to the cylinder. In the dark, fish do not show the same preference to hold station behind a cylinder though Kármán gait kinematics are the same. When oxygen consumption level is measured, it reveals that Kármán gaiting represents about half of the cost of swimming in the freestream.
Hip Strength as a Predictor of Ankle Sprains in Male Soccer Players: A Prospective Study

Published: November 2017

Context: 

Diminished hip-abductor strength has been suggested to increase the risk of noncontact lateral ankle sprains.

Objective: 

To determine prospectively whether baseline hip-abductor strength predicts future noncontact lateral ankle sprains in competitive male soccer players.

Design: 

Prospective cohort study.

Setting: 

Athletic training facilities and various athletic fields.

Patients or Other Participants: 

Two hundred ten competitive male soccer players.

Main Outcome Measure(s): 

Before the start of the sport season, isometric hip-abductor strength was measured bilaterally using a handheld dynamometer. Any previous history of ankle sprain, body mass index, age, height, and weight were documented. During the sport season (30 weeks), ankle injury status was recorded by team medical providers. Injured athletes were further classified based on the mechanism of injury. Only data from injured athletes who sustained noncontact lateral ankle sprains were used for analysis. Postseason, logistic regression was used to determine whether baseline hip strength predicted future noncontact lateral ankle sprains. A receiver operating characteristic curve was constructed for hip strength to determine the cutoff value for distinguishing between high-risk and low-risk outcomes.

Results: 

A total of 25 noncontact lateral ankle sprains were confirmed, for an overall annual incidence of 11.9%. Baseline hip-abductor strength was lower in injured players than in uninjured players (P = .008). Logistic regression indicated that impaired hip-abductor strength increased the future injury risk (odds ratio = 1.10 [95% confidence interval = 1.02, 1.18], P = .010). The strength cutoff to define high risk was ≤33.8% body weight, as determined by receiver operating characteristic curve analysis. For athletes classified as high risk, the probability of injury increased from 11.9% to 26.7%.

Conclusions: 

Reduced isometric hip-abductor strength predisposed competitive male soccer players to noncontact lateral ankle sprains.
