On the family Fissiphalliidae Martens, 1988, with descriptions of two new Amazonian species (Arachnida: Opiliones: Laniatores)
Authors: TOURINHO ANA LÚCIA , GONZÁLEZ ABEL PÉREZ
Published: May 2019

Two new species of Brazilian Fissiphalliidae are described. Fissiphallius chicoi n. sp. from Pará State, Gurupá municipality, whitewater floodplains (várzea), and Fissiphallius tucupi n. sp. from Amazonas State, Castanho municipality (paleovárzea). The number of species for this family in the Amazon rainforest increases from one to three. The two new species are closely related to Fissiphallius martensi Pinto-da-Rocha, 2004 from Amazonas State, Manaus. Fissiphalliidae and Zalmoxidae show remarkable similarities in somatic and genital morphology. Fissiphalliidae is kept as a family on the basis of its particular shape of the stragulum, but this character should be tested in a phylogenetic framework. A future phylogenetic analysis should determine if Fissiphalliidae is in fact the sister group of Zalmoxidae, or just a junior synonym. A key for identification, a distribution map, and notes on the distribution of the six species of Fissiphalliidae and the biology of the Amazonian species are given.
A new species of the false-scorpion family Cheliferidae from Thailand, with remarks on Ancistrochelifer and Metachelifer (Arachnida: Pseudoscorpiones)

It is distinguished by a series of characters shared by no other Hypocreadium species. The specimens are always slightly longer than wide, have a distinct anterior notch, have the vitelline fields confluent or nearly so in the forebody and have the terminal ends of the caeca pointing anteriorly. Other lepocreadiid species also recorded from New Caledonian waters are Lobatocreadium exiguum from P. fuscus, Intusatrium robustum from Bodianus perditio and B. loxozonus, Postlepidapedon secundum from Choerodon graphicus and Lepidapedoides angustus from Epinephelus fasciatus.
A new species of Ansonia Stoliczka 1872 (Anura: Bufonidae) from Central Peninsular Malaysia and a revised taxonomy for Ansonia from the Malay Peninsula
Authors: GRISMER L. LEE
Published: May 2019

A new, montane species of Ansonia is described from the state of Pahang in central, peninsular Malaysia on the basis of having a unique combination of head, body, digit, and color pattern characteristics. This new species is similar to A. malayana, to which it is closest geographically, but differs greatly in aspects of head morphology and body tuberculation. A review of Ansonia from the Malay Peninsula demonstrates that the population of A. malayana from Tasan, Chumphon Province, Thailand is A. kraensis and A. penangensis from Ulu Tahan, Pahang in peninsular Malaysia is not conspecific with A. penangensis from Pulau Penang but an additional, undescribed species ranging throughout northwestern, peninsular Malaysia.
Simuliidae (Diptera) of the Solomon Islands: new records and species, ecology, and biogeography
Authors: CRAIG D. A. , ENGLUND R. A. , Takaoka H.
Published: May 2019

Five species of Simuliidae are reported for the first time from the Solomon Islands of Santa Isabel, Malaita, and Makira, and Kolumbangara and Rendova of the New Georgia Island group. One newspecies, Simulium (Gomphostilbia) rhopaloides Craig, Englund & Takaoka, from Guadalcanal is described. The new material consists mainly of immature larvae, which, while allowing assignment to subgenus, do not always allow identification to species. The probability of other new species is suggested. The record for Makira is the most easterly known for the subgenus Morops, as are those for Gomphostilbia from Guadalcanal and Malaita. Larval habitats on the islands are illustrated. A brief synopsis of the paleogeology of the Solomon Islands is given as a basis for preliminary comments on distribution and biogeography of the known species of Simuliidae, now 10, for the Solomon Islands.

Authors: CHAKRABARTY PROSANTA , OLDFIELD RONALD G. , NG HEOK H.
Published: May 2019

Nandus prolixus sp. nov. is described from the Sepilok River drainage in Sabah, northeastern Borneo. This species is distinguished from its only Sundaic southeastern Asian congener, N. nebulosus, in having a longer, more produced snout (25.7–30.6% HL vs. 18.5–26.1), more lateralline scales (33–37 vs. 24–34), more scales below the lateral line (12 vs. 10–11), fewer spines in the dorsal fin (XIV vs. XV–XVI), and fewer pectoral-fin rays (15–16 vs. 17–19). It differs from N. nandus (from India) in having fewer lateral-line scales (33–37 vs. 42–55), fewer scales above the lateral line (4–5 vs. 6–7), fewer scales below the lateral line (12 vs. 14–18), more dorsal spines (XIV vs. XII–XIII), and the absence (vs. presence) of a distinct dark spot at the base of the caudal peduncle. It differs from N. oxyrhynchus (from mainland southeastern Asia) in having a more slender body (body depth 37.6–40.5% SL vs. 41.3–44.1) and a less steeply sloping predorsal profile.

Communicating Hurricane Risk with Virtual Reality: A Pilot Project
Authors: Bernhardt Jase , Snellings Jackson , Smiros Alexander , Bermejo Ivan , Rienzo Angela , Swan Carys
Published: May 2019

Landfalling hurricanes in the United States can inflict extreme damage and loss of life. The latter, particularly, can be caused by a host of socioeconomic factors, including insufficient understanding of risk by individuals expected to be impacted by the storm. Thus, we test the use of an emerging technology, virtual reality (VR), to enhance the communication of real-time risk from a hurricane forecast to make landfall. In this pilot study, individuals are presented with a hypothetical scenario where a major hurricane is forecast to impact their community within 48–72 h. The survey includes two different types of warning products related to the hypothetical hurricane: static text and maps emulating those traditionally used by media outlets and local officials to communicate risk, and a VR video simulating a hurricane landfall in a residential neighborhood. We survey two groups of equal size (each n = 62), one viewing both the VR simulation and traditional products, and the other only the latter. Each group was then asked a series of Likert-scale and open-ended questions to assess the effectiveness of both products. We determine that participants viewing both the VR and traditional products are significantly more likely to take action in preparation for the hypothetical landfall than those being exposed to just the traditional products. These results demonstrate that VR can be a useful component of hurricane warning products, and further work can be done to improve the effectiveness of such products and assess how broader segments of the population can access this information.
Tagged Core-Satellite Nanoassemblies: Role of Assembling Sequence on Surface-Enhanced Raman Scattering (SERS) Performance
Authors: Dey Priyanka , Thurecht Kristofer J. , Fredericks Peter M. , Blakey Idriss
Published: May 2019

Plasmonic nanoassemblies with amplified optical responses are attractive as chemo/bio sensors and diagnostic tracking agents. For real-life implementation, such nanostructures require a well-designed and controlled formation for maximizing the optical amplification. Forming these nanoassemblies typically requires numerous steps; however, the importance of the sequence of the steps is typically not discussed. Thus, here we have investigated the role of the sequence of tagging (or labeling, barcoding) of such plasmonic nanoassemblies with Raman active molecules in a quest to maximize the surface-enhanced Raman scattering (SERS) enhancement that could be achieved from the nanoassemblies. We have chosen the core-satellite nanoassembly arrangement to study the role of tagging sequence because it allows us to keep structural parameters constant that would otherwise influence the SERS amplification. We demonstrate that incorporating the tag molecule at an assembly point before formation of the nanojunctions leads to more tag molecules being positioned at the core-satellite nanojunctions, thereby resulting in higher SERS signal enhancement. This will thus prove to be a useful tool in fully utilizing the nanoassembly morphology generated hot-spot and maximizing its SERS performance.
Caregivers’ Experiences With Food Insecurity Screening and Impact of Food Insecurity Resources
Authors: Orr Colin J. , Chauvenet Christina , Ozgun Holly , Pamanes-Duran Claudia , Flower Kori B.
Published: May 2019

We explored caregivers’ experiences with food insecurity screening in a primary care setting and the impact of resources provided. English- and Spanish-speaking food insecure caregivers of children aged 1 to 5 years were recruited. In-depth individual semistructured interviews were conducted (n = 17) eliciting caregivers’ experiences with food insecurity, clinic screening, and resources provided. Interviews were audio-recorded and transcribed verbatim. Interviews were double-coded and thematic analysis was used to identify themes and subthemes. All caregivers described multiple and repeat experiences with food insecurity. Food insecurity screening was acceptable, but families were not always connected with resources. Caregivers described WIC (Women, Infants, and Children) as the most commonly used program to address food insecurity and infrequently utilized other food insecurity resources. Screening for food insecurity in primary care was generally well accepted by this sample of food insecure caregivers. Future studies are needed to determine how to improve connecting resources with families most in need.
Super-twisting sliding mode control design based on Lyapunov criteria for attitude tracking control and vibration suppression of a flexible spacecraft
Authors: Nadafi Reza , Kabganian Mansour , Kamali Ali , Hossein Nejad Mahboobeh
Published: May 2019

The three-axis attitude tracking manoeuvre and vibration suppression of a flexible spacecraft in the presence of external disturbances are investigated in this paper. The spacecraft consists of a rigid hub and two flexible appendages. The Euler–Bernoulli beam theory is used to model the flexible parts. The attitude dynamic equations of motion are derived using the law of conservation of angular momentum, and the flexural equations are derived. The attitude of the spacecraft is represented using the quaternion parameters. The controller is designed based on the super-twisting sliding mode control. The sliding surfaces are introduced and the global asymptotic stability of the flexible spacecraft on the sliding surfaces is assured via Lyapunov method. The control law is designed such that the sliding condition is satisfied and the system reaches the sliding surfaces in finite time. The simulation results verify the performance of the controller in the presence of bounded disturbances, sensor noises and abrupt changes in parameters.

Objective/significance

Based on the urgent needs of the status quo of urban anti-terrorism, combining the present situation of intelligent city construction, we carry out the research on the key problems such as the collection and analysis of counter-terrorism information for urban environment. This paper puts forward a kind of city anti-terrorism information perception system based on the Internet of things, and realizes to improve the level of surveillance and early warning of terrorist activities facing the urban environment.

Method/Process

The system collects and merges the heterogeneous information of terrorism, which is based on the information perception layer, the intelligence identification layer and the intelligence inference layer, which is based on the city's focal area. To filter suspicious information by constructing a semantic database of terrorist action signals Combined with complex event processing and machine learning technology, real-time monitoring and mining prediction of mass event flow, using the comparison between historical data of terrorist attacks and real-time data, increased the area of counter-terrorism intelligence.

Results/Conclusions

We hope to provide a better model and an exploratory study on the construction of the counter-terrorism early warning for the urban environment.

Authors: Chinyere Ogbuanya T , Afeez Yekinni S
Published: May 2019

This study investigated the influence of emotional intelligence ability level of electrical/electronic technology university students on academic motivation and attitude to study. The study was conducted at one conventional university and one university of technology. The data for study were obtained through the use of a questionnaire which elicited information on the students’ emotional intelligence ability level, level of academic motivation and students’ attitude to study. The data were analyzed using mean, standard deviation, Cohen's d and single and multiple regression analysis. Meanwhile, hypotheses were tested using T-test and analysis of variance. The results of the study revealed that the student in conventional university and one university of technology has high level of emotional intelligence, academic motivation and favourable attitude to study. The effect size of students, with regard to their emotional intelligence ability level in two universities is weak. The emotional intelligence investigated was found to be significantly and positively associated with the respondents’ level of academic motivation and students’ attitude to study.
Does Stereotype Threat Deteriorate Academic Performance of High School Students With Learning Disabilities? The Buffering Role of Psychological Disengagement
Authors: Zhao Fengqing , Li Sen , Li Tianran , Yu Guoliang
Published: May 2019

The academic underperformance of high school students with learning disabilities may reduce their access to higher education and decrease their employment opportunities. Based on stereotype threat hypothesis, the present study examined the role of stereotype threat in academic performance among adolescents with learning disabilities and the moderating role of psychological disengagement in this relation. In Study 1, 120 students with learning disabilities finished the measures of stereotype threat vulnerability and psychological disengagement, and their academic score at two time points were collected. Results showed that students who are more vulnerable to stereotype threat tend to have a lower academic score at Time 2 even after controlling for academic score at Time 1, and this relation was moderated by psychological disengagement. In Study 2, 62 sophomore students with learning disabilities finished measures of stereotype threat, academic persistence, and psychological disengagement. The results showed that the effect of stereotype threat on academic persistence was significant among students who were of low psychological disengagement, while this effect was not significant among students who were psychologically disengaged in academics. These results emphasize the individual differences of learning disabled students’ response to stereotype threat and have significant implications for framing targeted interventions.
Improving the income status of smallholder vegetable farmers through a homestead food garden intervention
Authors: Bahta YT , Owusu-Sekyere Enoch
Published: May 2019

In this article, we assess how a homestead food garden intervention influences the income of participating vegetable farmers in South Africa. The findings show that there is a significant improvement in the income of these farmers. Specifically, the participating vegetable farmers observed an increment in their gross margins of between 39.28% and 44.49%. Our findings further indicate that households with larger farm plots have higher gross margins in a production season. The underlying impact of the participating households with farmland larger than one acre is a surge in growth margin of 35.33–44.61% relative to those owning less than1 acre. Given the benefits of the intervention, stakeholders and policymakers should expand the programme and design strategies that will foster participation. Policies to consider include the availability of farm plots and the readiness of the household to participate in vegetable production. Other Southern African Development Communities as an important food policy intervention, which can improve household income, can adopt the programme.

Published: May 2019

Pregnancy can be accompanied by serious health risks to mother and child, such as pre-eclampsia, premature birth and postpartum haemorrhage. Understanding of the normal physiology of uterine function is essential to an improved management of such risks. Here we focus on the physiology of the smooth muscle fibres which make up the bulk of the uterine wall and which generate the forceful contractions that accompany parturition. We survey computational methods that integrate mathematical modelling with data analysis and thereby aid the discovery of new therapeutic targets that, according to clinical needs, can be manipulated to either stop contractions or cause the uterine wall muscle to become active.
Moving away from opportunity? Social networks and access to social services
Authors: Jeon Jae Sik
Published: May 2019

Strong social connections often deter residential mobility beyond reach of the social network. A missing link in the body of research on this subject is the significance of the role of social networks in pooling resources for costly services and neighbourhood-level access to social services. Few have explored whether assistance from local social service agencies may substitute for practical help from social networks, thereby enabling low-income assisted renters to locate housing in more desirable neighbourhoods. Relying on data from the Moving to Opportunity experiment, this article examines the impact of social networks and social services on the dynamics of residential mobility. I find that the existence of social networks in the place movers left behind tends to increase the likelihood of moving back, but this likelihood varies with current access to social service providers and distance moved. These findings suggest that policy efforts in spatial dispersion of poverty should pay close attention to the geography of social services.
Cultural Humility as a Spiritually Focused Intervention in Correctional Settings: The Role of Therapists’ Multicultural Orientation
Authors: Gafford Jennifer , Raines Tara C. , Sinha Sree , DeBlaere Cirleen , Davis Don E. , Hook Joshua N. , Owen Jesse
Published: May 2019

The role of religion/spirituality (R/S) in the lives of incarcerated individuals is complex. Inmates may draw on R/S as a coping strategy, as a way to place responsibility, or as an approach to creating meaning. The importance of using R/S as a coping strategy can be amplified in the context of a correctional setting. While some attention has focused on the effectiveness of faith-based services in jails and prisons, very little emphasis has been placed on using those constructs in psychotherapy within the correctional context. Accordingly, this article explores the application of the multicultural orientation framework—including the important tenets of therapists’ cultural humility, cultural comfort, and cultural opportunities—into psychotherapy practices with incarcerated individuals. In doing so, we will focus on how cultural humility can assist in addressing intersecting identities, including spirituality, race/ethnicity, socioeconomic status (SES), and gender identity to enhance the process and outcome of therapy. We will discuss how cultural humility can be effectively used to address common challenges for therapists when working with R/S issues in corrections and conclude with two case studies to illustrate the application.
Military Service and Legislative Agendas: A Study of Legislators in Four States
Authors: Best Rebecca , Vonnahme Greg
Published: May 2019

Candidates often highlight military experience on the campaign trail. Do they also govern differently? This study examines whether and how military experience is associated with state lawmaking. We examine legislative productivity, success rates, and the substantive content of legislation with a large original data set. The data include over 60,000 bills introduced in four state legislatures over a 10-year time span, coded for their substantive focus. It also includes information on characteristics of over 4,000 legislators. Our analysis of these data indicates that veterans do not differ in overall levels of productivity but do have common legislative agendas. Veterans’ shared legislative agendas are not narrowly confined to defense or security issues but vary depending on state context. This is, to our knowledge, the most extensive empirical analysis of the legislative behavior of veterans in a single study.
The Housing Struggle in Milan in the 1970s: Influences and Particularities
Authors: Soresina Marco
Published: May 2019

The article examines the housing occupation movements in Milan in 1969-1975, relating them to the restricted supply of cheap housing—a situation that created difficulties for newly arrived immigrant. Housing occupation activists were influenced by the experience of squatting in other European cities, a phenomenon that particularly fascinated the educated young, who participated in the movement, supported by organizations of the radical left. The movement’s political project was to take the class struggle outside the factories, to attack “urban income growth” as a tool of capitalist domination. Compared with other Italian experiences, there was less involvement from the underclass, and the aim of obtaining a house was secondary to the project of maintaining political conflict at a high level. The movement waned in the late 1970s, due to the fact that the revolutionary groups’ drive for political mobilization no longer coincided with the social housing needs of young people.
Assessing professional competence: a critical review of the Annual Review of Competence Progression
Authors: Woolf Katherine , Page Michael , Viney Rowena
Published: May 2019

The Annual Review of Competence Progression is used to determine whether trainee doctors in the United Kingdom are safe and competent to progress to the next training stage.

In this article we provide evidence to inform recommendations to enhance the validity of the summative and formative elements of the Annual Review of Competency Progression. The work was commissioned as part of a Health Education England review.

We systematic searched the peer reviewed and grey literature, synthesising findings with information from national, local and specialty-specific Annual Review of Competence Progression guidance, critically evaluating the findings in the context of literature on assessing competence in medical education.

National guidance lacked detail resulting in variability across locations and specialties, threatening validity and reliability. Trainees and trainers were concerned that the Annual Review of Competence Progression only reliably identifies the most poorly performing trainees. Feedback is not routinely provided, which can leave those with performance difficulties unsupported and high performers demotivated. Variability in the provision and quality of feedback can negatively affect learning.

The Annual Review of Competence Progression functions as a high-stakes assessment, likely to have a significant impact on patient care. It should be subject to the same rigorous evaluation as other high-stakes assessments; there should be consistency in procedures across locations, specialties and grades; and all trainees should receive high-quality feedback.
A Dynamic Model of the Effects of Feedback-Seeking Behavior and Organizational Commitment on Newcomer Turnover
Authors: Vandenberghe Christian , Landry Guylaine , Bentein Kathleen , Anseel Frederik , Mignonac Karim , Roussel Patrice
Published: May 2019

Theory and conventional wisdom suggest that progressive reduction of feedback-seeking behavior (FSB) during entry is indicative of work adjustment. We argue that a downside of this process is that newcomers’ social integration and acculturation may be weakened. This suggests declining levels of FSB may result in decreased organizational commitment across time and ultimately greater turnover likelihood. These predictions were examined in two longitudinal studies (Study 1, N = 158; Study 2, N = 170) among newcomers. In both studies, FSB by supervisor inquiry was found to decline across time, and the decrease in FSB preceded a steeper decline in affective organizational commitment. In Study 1, the decline of commitment also resulted in a steeper decrease in FSB. Study 2 further found the decline in commitment to mediate the relationship between the decrease in FSB and increased turnover intention. Finally, increased turnover intention mediated the relationship between the decline in commitment and increased turnover the following year. Bridging research on FSB and organizational commitment, these findings shed new light on the influence of the dynamics of FSB on newcomer turnover.
Safety Culture and Patient Safety Outcomes in East Asia: A Literature Review
Authors: Lee Seung Eun , Quinn Brenna L.
Published: May 2019

This review examined associations between safety culture aspects and patient safety outcomes in East Asian hospitals and identified relevant research priorities. Using the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines, 16 articles were identified for review. Patient safety nursing activity was the most commonly investigated outcome in relation to safety culture aspects. Among safety culture aspects, feedback and communication, frequency of event reporting, teamwork within units, and managers’ support for patient safety were most significantly related to patient safety outcomes. Areas for further research include the use of theory or theoretical frameworks, consensus upon the scoring strategies for computation of safety culture scores, and selecting appropriate units of analysis and statistical analyses. Finally, researchers should examine relations between unit-specific and nation-specific safety culture and patient safety outcomes, given the influence of cultural attitudes and behaviors on patient safety.

A 65-year-old man had intermittent abdominal pain for the previous 2 years. This pain suddenly became worse with a fever and elevated inflammatory markers. We took a while to diagnose the patient with mesenteric panniculitis (MP). Although imaging findings suggested MP, we needed to rule out other diseases. Choosing a treatment for the patient also took some time and we finally used glucocorticoid to cure the patient.
Identification of potential long noncoding RNA associated with nasopharyngeal carcinoma using deep sequencing
Authors: Xu Yu-Zhong , Chen Fang-Fang , Zhang Yu , Liang Hui , Li Xiao-Jun , He Chen
Published: May 2019

Objective

To identify differentially expressed long noncoding RNAs (lncRNAs) in nasopharyngeal carcinoma (NPC) compared with chronic nasopharyngitis (CNP) tissues.

Methods

This prospective cohort study enrolled patients with NPC and CNP. The levels of lncRNAs in NPC and CNP tissues was detected by deep sequencing and quantitative polymerase chain reaction. Kyoto Encyclopedia of Genes and Genomes pathway analysis and antisense prediction were performed to reveal the function of differentially expressed lncRNAs (DELs). Receiver operating characteristic (ROC) curve and correlation analyses were used to evaluate the clinical and prognostic value of lncRNAs.

Results

A total of 30 NPC and 27 CNP tissues were analysed. A total of 296 DELs were identified. LncRNAs ENSG00000227084 and ENSG00000230489 might play important roles in the development of NPC by interfering with the Rap1 signalling pathway and natural killer cell-mediated cytotoxicity, respectively. Antisense prediction showed that lncRNA ENSG00000230489 was paired with VAV3 mRNA. LncRNAs ENSG00000230489 (area under the ROC curve = 0.9138) and ENSG00000227084 (area under the ROC curve = 0.8037) may be diagnostic markers for NPC. Furthermore, low levels of ENSG00000230489 was positively associated with distant metastasis.

Conclusion

LncRNAs ENSG00000230489 and ENSG00000227084 may be potential diagnostic markers and therapeutic targets for NPC.
Geographies of infrastructure 1: Economies
Authors: Furlong Kathryn
Published: May 2019

This progress report explores economies of infrastructure, concentrating on questions of financialization. Interest in infrastructure financialization has grown with concern about financialization more broadly, coming to dominate discussions on economies of infrastructure. Below, I engage with research that explores what infrastructure financialization entails, its scope, as well as the mathematical infrastructures that support it. Questioning the common presentation of financialization as a complete break with past economies of infrastructure, I bookend this report with its links to – and continuities with – debt-led infrastructure development, which prevailed in the post-war period and remains of great importance in contemporary economies of infrastructure.

This article presents a detailed, yet simple control scheme based on a flywheel energy storage system for dynamic performance enhancement. A permanent magnet machine-based 70 MW flywheel energy storage system is incorporated in a wind-integrated Western System Coordinating Council multimachine system. An elaborate mathematical modelling of the flywheel energy storage system as an effective current source is provided along with the wind-embedded multimachine system to investigate the transient stability profile of the said system. Generator speed and voltage are continuously monitored by the flywheel energy storage system plant controllers, and subsequent real and reactive reference power commands are generated. Two first-order lag blocks are employed to emulate the grid side and machine side converters’ dynamics. The developed non-linear model is tested against three-phase faults in a variable wind condition, and the effectiveness of the control scheme is confirmed by the enormous damping and extension in the stability margin of the system.
Optimal power flow incorporating wind power and optimally allocated energy storage

Published: May 2019

The rapid growth of wind power poses new challenges for power system operators and electricity marketers. The benefits of using wind power are emission reduction and decrease in consumption of conventional resources. But the inherent nature of wind energy poses challenges in the power system operation and planning. In order to consider the wind power as firm power, auxiliary energy storage is added as a backup to encounter the variations in wind power. In this article, optimal power flow with wind and energy storage is developed. The energy storage systems are installed as a standby of wind generators to meet the demand consistently. The objective is to minimize the loss by optimal location and sizing of energy storage systems. With the optimally located energy storage systems, optimal power flow is carried out using shuffled frog-leaping algorithm technique and tested on IEEE 30 bus system.

This study presents a multimodal evacuation microsimulation modeling framework. The paper first determines optimum marshal point locations and transit routes, then examines network conditions through traffic microsimulation of a mass evacuation of the Halifax Peninsula, Canada. The proposed optimization modeling approach identifies marshal point locations based on transit demand obtained from a Halifax Regional Transport network model. A mixed integer linear programming (MILP) technique is used to formulate the marshal point location and transit route choice problem. The study proposes a novel approach to solving the MILP problem, using the “branch and cut” algorithm, which demonstrates superiority in computation time and production of quality solutions. The optimization model determines 135 marshal points and 12 transit routes to evacuate approximately 8,400 transit-dependent individuals. Transit demand and marshal point locations are found to be concentrated at the core of the peninsula. The microsimulation modeling takes a dynamic traffic assignment-based approach. The simulation model predicts that it takes 22 h to evacuate all auto users but just 7 h for the transit-dependent population. The study reveals that the transit system has excess capacity to assist evacuees who switch from auto and other modes. Local traffic congestion prolongs the evacuation of a few densely-populated zones in the downtown core of the peninsula. The findings of this research help policy-makers understand the impacts of marshal point locations and transit route choice decisions on multimodal evacuation performance, and provide insights into emergency planning of multimodal evacuations under "mode switch" and transit-based evacuation scenarios.
Analysis of the Stability of Thawing Slopes by Random Finite Element Method
Authors: Dong Shaoyang , Yu Xiong (Bill)
Published: May 2019

A significant number of landslides occur in cold regions because of freezing and thawing cycles. The instability of thawing slopes can cause serious damage to transportation infrastructure and property, and even loss of human life. This type of landslide is difficult to analyze by the traditional limit-equilibrium methods, however, because of the complicated multi-physics processes involved. This paper describes a holistic microstructure-based random finite element model (RFEM) to simulate the stability of a thawing slope. The RFEM model is developed to simulate the bulk behaviors of frozen and unfrozen soils based on the behaviors of individual phases. The phase coded image of a frozen silty clay is first custom built and then converted into a finite element model. The mechanical behaviors of individual phases of the frozen soil are calibrated by uniaxial compressive test. The triaxial test is then simulated by RFEM to obtain the shear strength parameters of frozen and unfrozen soils. Coupled thermal-mechanical REFM models are developed to simulate the effects of temperature on the displacement field and stress field in the slope. From the results, the local factor of safety field can be determined. The development of local factor of safety and potential failure surface associated with the thawing process over a typical year are simulated by this new model. The variations in the stability of thawing slopes predicted by this model are consistent with field observations as well as the global-wise slope stability analysis.

Background:

Altered kinematics and persisting ankle instability have been associated with degenerative changes and osteochondral lesions.

Purpose:

To study the effect of ligament reconstruction surgery with suture tape augmentation (isolated anterior talofibular ligament [ATFL] vs combined ATFL and calcaneofibular ligament [CFL]) after lateral ligament ruptures (combined ATFL and CFL) on foot-ankle kinematics during simulated gait.

Study Design:

Controlled laboratory study.

Methods:

Five fresh-frozen cadaveric specimens were tested in a custom-built gait simulator in 5 different conditions: intact, ATFL rupture, ATFL-CFL rupture, ATFL-CFL reconstruction, and ATFL reconstruction. For each condition, range of motion (ROM) and the average angle (AA) in the hindfoot and midfoot joints were calculated during the stance phase of normal and inverted gait.

Results:

Ligament ruptures mainly changed ROM in the hindfoot and the AA in the hindfoot and midfoot and influenced the kinematics in all 3 movement directions. Combined ligament reconstruction was able to restore ROM in inversion-eversion in 4 of the 5 joints and ROM in internal-external rotation and dorsiflexion-plantarflexion in 3 of the 5 joints. It was also able to restore the AA in inversion-eversion in 2 of the 5 joints, the AA in internal-external rotation in all joints, and the AA in dorsiflexion-plantarflexion in 1 of the joints. Isolated ATFL reconstruction was able to restore ROM in inversion-eversion and internal-external rotation in 3 of the 5 joints and ROM in dorsiflexion-plantarflexion in 2 of the 5 joints. Isolated reconstruction was also able to restore the AA in inversion-eversion and dorsiflexion-plantarflexion in 2 of the joints and the AA in internal-external rotation in 3 of the joints. Both isolated reconstruction and combined reconstruction were most successful in restoring motion in the tibiocalcaneal and talonavicular joints and least successful in restoring motion in the talocalcaneal joint. However, combined reconstruction was still better at restoring motion in the talocalcaneal joint than isolated reconstruction (1/3 for ROM and 1/3 for the AA with isolated reconstruction compared to 1/3 for ROM and 2/3 for the AA with combined reconstruction).

Conclusion:

Combined ATFL-CFL reconstruction showed better restored motion immediately after surgery than isolated ATFL reconstruction after a combined ATFL-CFL rupture.

Clinical Relevance:

This study shows that ligament reconstruction with suture tape augmentation is able to partially restore kinematics in the hindfoot and midfoot at the time of surgery. In clinical applications, where the classic Broström-Gould technique is followed by augmentation with suture tape, this procedure may protect the repaired ligament during healing by limiting excessive ROM after a ligament rupture.
The course of hematocrit value along the length of a dialyzer’s fiber: Hemoconcentration modeling and validation methods

Published: May 2019

Objectives:

Contemporary therapies for chronic kidney disease patients encompass a wide range of hemodialysis treatments, most of which rely greatly on dialyzers and hemofilters. The filtration process taking place in these devices with respect to the hemodynamic characteristics of the flow, has not yet been fully investigated. This study aims at improving the understanding of hemodynamics in a dialyzer by employing experimental methods and mathematical models.

Methods:

A semiempirical model has been formulated based on the principles of hemodynamics, considering the dominant phenomena of filtration-backfiltration and the corresponding driving forces. An in vitro hemodialysis circuit was accordingly assembled for experimental data acquisition, and subsequently for model validation. The circuit consisted of two dialyzers arranged in sequential order, in pursuance of increasing the number of sampling points. Fresh, heparinized porcine blood was used throughout the course of this study. Pressure and flow data obtained from in vitro investigations with the hemodialysis circuit were used as an input for the semiempirical model.

Findings:

The model predicted a substantial divergence in the course of hematocrit value along the length of the hollow fibers, which is corroborated by the experimental data. Particularly in certain operational conditions, hematocrit rose from 25% at the inlet to 65% halfway along the dialyzers’ length, to end at 30% at the outlet.

Conclusion:

Validation of the model’s predictions with experimental data demonstrated a very good agreement, confirming the model’s accuracy. Potential implementation of the model in clinical practice in the future might contribute greatly to an improved hemodialysis experience.
Mindful Eating (Not the Kind You Think) and an Interview With Dr Kevin Walker
Authors: Terry Paul E.
Published: May 2019

Could it be that self-help concepts like mindfulness meditation have a short shelf life because they’re just that, too much about the self and not enough about something far more important? This editorial describes Kevin Walker’s research and his new book, “ The Grand Food Bargain and the Mindless Drive for More.” Walker’s book shows why the dozens of federal and state agencies with a slice of accountability for food health and safety are predictably and routinely outgunned by the food industry with respect to influencing the public’s health. Describing the dozens of interagency agreements relating to agriculture policies, Walker writes that “food safety in America is held together using the policy equivalent of baling wire and duct tape.” Most health promotion professionals who consider the term mindful eating likely first think about principles that relate to being present and techniques that put you in closer touch with the flavors, colors, or textures of your food. In addition to focusing on how creamy a texture feels on our tongues, might advocacy for “mindful eating” have a more abiding impact if it brought with it a deep appreciation for how our food choices affect the health and sustainability of our communities and our Mother Earth? Changing food from an afterthought to a daily reminder about environmental sustainability is a multidimensional challenge that will require multisectoral partnerships and solutions.
