Malo kingi: A new species of Irukandji jellyfish (Cnidaria: Cubozoa: Carybdeida), possibly lethal to humans, from Queensland, Australia
Authors: GERSHWIN LISA-ANN
Published: July 2019

Irukandji stings may be lethal to humans, and yet, until late 2005, only one of the many suspected Irukandji stingers had been formally named and classified. This paper describes Malo kingi, n. sp., which is apparently responsible for a recent fatality. This species differs from all other cubozoans in having halo-like rings of tissue encircling the tentacles, with club-shaped Type 4 microbasic mastigophores inserted end-on around the periphery of the rings. It further differs from its only current congener, Malo maxima, in having: a much smaller, more rounded body; different tubule winding patterns in the undischarged nematocysts; spines confined to the distal-most portion of the shaft in the discharged nematocysts; relatively broader pedalia; somewhat less well defined rhopalial horns; and perradial lappets with a greater number of nematocyst warts and nipple-like terminal extensions. Much additional work is needed to better understand the general biology of this and other dangerous species so as to prevent further fatalities, debilitating illnesses, and threats to the tourism industry resulting from the marine stinger problem. Treatment of envenomations, management issues regarding sting prevention, and the related implications for tourism, all rely on being able to consistently and accurately identify public health hazards. The need still exists for an aggressive awareness campaign aimed at residents and visitors regarding education and prevention of Irukandji stings.
On the spider genus Cryptachaea from Peru, Bolivia and cave environments in Brazil: a new species, additional descriptions and new records (Araneae, Theridiidae)
Authors: SANTANNA MANOELA , RODRIGUES EVERTON NEI LOPES , CIZAUSKAS IGOR , BRESCOVIT ANTONIO DOMINGOS
Published: July 2019

In this paper a new species of Cryptachaea Archer, 1946 based on males and females is described from Brazilian caves: Cryptachaea pilar Santanna & Rodrigues, new species from the states of Minas Gerais and São Paulo. The females of Cryptachaea parana (Levi, 1963) and C. schneirlai (Levi, 1959) are described and illustrated for the first time. Cryptachaea uviana (Levi, 1963) is synonymized with C. migrans (Keyserling, 1884). The species Cryptachaea alacris (Keyserling, 1884), C. benivia Rodrigues & Poeta, 2015, C. parana (Levi, 1963) and C. schneirlai (Levi, 1959) are recorded for the first from Brazil; and C. migrans for the first time from Bolivia. Additionally, new records from Brazilian caves are provided for Cryptachaea parana, from the states of Tocantins, Goiás, Minas Gerais, Mato Grosso do Sul and São Paulo; C. schneirlai and C. alacris from the state of Pará; C. dea (Buckup & Marques, 2006) and C. rioensis (Levi, 1963) from Pará and Minas Gerais, C. jequirituba (Levi, 1963) from Minas Gerais and C. benivia from São Paulo.
Checklist of the Brachyura of the Brazilian Amazon Coastal Zone and knowledge status of their larval development
Authors: DE LIMA FRANCIELLY ALCÂNTARA , MARTINELLI-LEMOS JUSSARA MORETTO
Published: July 2019

This bibliographic review includes all brachyuran species listed for the Brazilian Amazon Coastal Zone (covering the occurrence of species in the states of Amapá, Pará, and Maranhão), with respective larval development either fully or partially described. Information provided include the current taxon name, taxon authorship, larval stages described, and habitat of the adult of each species. A total of 194 species were recorded in the study area. Of these, 49 (25%) have the larval stages completely described, 25 (13%) have incomplete descriptions of the larval development with at least one stage described, and most of them, 120 species (62%), do not have morphological descriptions of any larval stage. This is clearly a large gap that needs to be filled for the advancement of the knowledge of crab life histories in a unique area of coastal biodiversity. More so because this area faces threats from the pink shrimp fishery and oil prospection activities.
Observations of the first GameSense-branded responsible gambling centre in a US casino
Authors: Gray Heather M , Keating Layne , Shaffer Howard J , LaPlante Debi A
Published: July 2019

Objective:

To help mitigate potential gambling harm, responsible gambling information centres are launching across casino venues in North America. The launch of the first such centre in the USA provided an opportunity to achieve three goals: (1) document the centre’s reach among casino patrons, (2) generate a comprehensive description of services provided, and (3) explore the potential for a dose–response relationship between centre exposure and gambling beliefs and behaviour.

Design:

We documented services provided and surveyed consecutive centre visitors.

Setting:

We achieved these goals at the GameSense Info Center, located in the first Massachusetts casino.

Method:

Programme staff recorded their services via electronic checklist and administered one-page surveys to visitors with whom they discussed problem or responsible gambling.

Results:

Programme staff reported engaging directly with approximately 1% of daily patrons. About 70% of their interactions were casual. During conversations that did move beyond a casual nature, programme staff typically provided information about responsible gambling, consistent with patrons’ self-reported needs and concerns. Finally, among a sample of patrons who repeatedly engaged with programme staff at the most involved level ( N = 129), those with relatively little programme exposure were more likely to hold an accurate gambling belief but less likely to report having set time limits on their casino visits.

Conclusion:

We did not observe support for the notion that using an on-site information centre to teach patrons about important gambling concepts is associated with more responsible gambling behaviour.
Complex anti-synchronization of two indistinguishable chaotic complex nonlinear models
Authors: Mahmoud Emad E , Al-Adwani Madeha A
Published: July 2019

The principal target of this work is to introduce and examine a novel kind of complex synchronization. This sort may be called complex anti-synchronization. There are surprising properties of complex anti-synchronization that do not exist in the writing, for example, (1) this sort of synchronization can dissect just for complex nonlinear frameworks. (2) The complex anti-synchronization contains or connects two sorts of synchronizations (anti-synchronization and complete synchronization). Anti-synchronization happens between the real part of main framework and the imaginary part of the slave framework, although complete synchronization accomplishes between the real part of slave framework and the imaginary part of the main framework. (3) In complex anti-synchronization, the attractors of the essential and slave structures are moving symmetrical to each other with a similar structure. (4) The state variable of the standard framework synchronizes with an other state variable of the slave structure. An explanation of complex anti-synchronization is presented for two indistinguishable chaotic complex nonlinear frameworks. In view of the Lyapunov function, a plan is intended to accomplish complex anti-synchronization of disordered or chaotic attractors of these frameworks. The effectiveness of the obtained results is outlined by a reenactment illustration. Numerical outcomes are plotted to show state variable, modulus errors, phase errors and the development of the attractors of these chaotic frameworks after synchronization to demonstrate that complex anti-synchronization is accomplished.
Teaching Data Reproducibility through Service Learning
Authors: Nurse Anne M. , Staiger Trish
Published: July 2019

Data reproducibility is becoming increasingly important in the social sciences, but it has yet to be incorporated into many undergraduate sociology programs. This note describes a service-learning activity that can be added to an introductory statistics course. Students partner with a nonprofit and analyze quantitative data to answer questions selected by the agency. Reproducibility is the central mechanism of communication between the nonprofit, the students, and the course instructor. An assessment of the project suggests that students achieve an understanding of how to create reproducible data. They also come to see its value as a method of communication about data decisions.
Life prediction of slewing bearing based on isometric mapping and fuzzy support vector regression
Authors: Bao Weigang , Wang Hua , Chen Jie , Zhang Bo , Ding Peng , Wu Jie , He Peiyu
Published: July 2019

The monitoring data of slewing bearing is massive. In order to establish accurate life prediction model from complex vibration signal of slewing bearing, a life prediction method based on manifold learning and fuzzy support vector regression (SVR) is proposed. Firstly, the multiple features are extracted from time domain and time-frequency domain. Then isometric mapping (ISOMAP) is used to reduce high-dimensional features to low-dimensional features that can reflect degeneration of slewing bearing well. Finally, the fuzzy SVR is used to predict the life degradation trend of slewing bearing. The results show that: (1) Multi-feature fusion after ISOMAP can obtain more comprehensive degradation indicator. (2) The complexity of the life prediction model is simplified and the real-time life degradation trend of slewing bearing can be well predicted by fuzzy SVR, so it is very suitable to predict life degradation trend of slewing bearing based on massive data well. The time of prediction on average is reduced by 72.7%. The mean absolute error (MAE) and root mean square error (RMSE) of prediction are reduced by 73% and 59% respectively compared with traditional methods. The accuracy of prediction is greatly improved.
Preparation of Orientation and Mobility Specialist Students Who are Blind and Have Low Vision: Survey of Faculty Who Teach Blindfold and Simulation Cane Courses
Authors: Griffin-Shirley Nora , Bozeman Laura , Obiero Nereah A. , Steinle Kyle J. , Page Anita
Published: July 2019

Introduction:

The purpose of this study was to survey the faculty of personnel preparation programs that train orientation and mobility (O&M) specialists in the identification of accommodations, teaching techniques, and resources needed to teach students who are visually impaired (i.e., those who are blind or have low vision) and who are enrolled in blindfold and simulation cane courses (hereafter, cane courses). Cane courses are used to teach the techniques of independent cane travel, and they require total visual occlusion using blindfolds as well as simulated low vision using goggles that depict different visual acuities and field losses.

Methods:

This study surveyed personnel preparation programs training O&M specialists with an online questionnaire with open-ended items to identify the program’s required accommodations, teaching techniques, and resources needed to teach visually impaired students who are enrolled in cane courses. The survey was e-mailed to 22 universities in North America, which have personnel preparation programs for O&M specialists and asked for responses from individuals who teach cane courses. Descriptive statistics were used to analyze the survey data.

Results:

Results showed that the format of the cane courses was varied, a variety of accommodations and teaching strategies were used, and the universities’ office of disabled students generally did not know how to accommodate these courses.

Discussion:

A need exists for a student who is visually impaired to be an experienced traveler and to be knowledgeable about what accommodations and strategies he or she will use when they need to teach a fellow student during a cane course. Visually impaired students must be able to monitor the safety of their peers as well as the changing dynamics of the environment in which they are working.

Implication for practitioners:

To effectively teach visually impaired students who are enrolled in cane courses, university faculty teaching these courses could request prospective visually impaired students to provide documentation regarding their travel skills prior to acceptance into a personnel preparation program in O&M. In addition, students with visual impairments need to discuss with their universities’ office of disabled students and legal counsel what reasonable accommodations are relevant for visually impaired students enrolled in the cane courses and what accommodations they believe the universities are committed to providing these students.

Published: July 2019

Microminipigs have become an attractive animal model for toxicology and pharmacology studies and for human disease models, owing to their manageable size. Although there are numerous reports of spontaneous age-related lesions in mice, rats, dogs, and monkeys, those in minipigs are scarce. In the present study, spontaneous age-related histopathological changes were investigated using 37 microminipigs (20 males and 17 females) that were 6 months to 10 years of age. Abnormal deposits of materials were evident in several animals from 6 years of age, and these deposits included amyloid in the renal medulla, thyroid gland, and adrenal gland, hyaline droplets in glomeruli, and fibrillar inclusions in neurons. Arterial sclerosing changes (intimal thickening, intimal proliferation, and medial mineralization) and proliferative lesions (hyperplasia of hepatocytes, follicular cells, Leydig cells, and uterine endometrial glands) were present at 4 years of age and beyond. Renal adenoma, uterine leiomyoma, and Leydig cell tumor were observed in several microminipigs. Moreover, glomerulosclerosis, renal interstitial fibrosis, thymic involution, and adrenocortical cell vacuolation were common in aging microminipigs. Since knowledge of age-related changes is helpful for pathologists, the basic information obtained in this study will be a useful reference for all future toxicity evaluations in microminipigs.
Keeping the paschal lamb: Exodus 12.6 and the question of sacrifice in the Passover-of-Egypt
Authors: Thames John Tracy
Published: July 2019

The paschal prescription in Exodus 12.3-6—attributed to the Priestly Source—that requires the Israelites to keep an animal four days prior to slaughtering it is an enigmatic episode unparalleled in other biblical accounts of Passover. Modern discussions often disregard the prescription as a faux rite created through textual harmonization of apparently disparate dating traditions for Passover. This discussion demonstrates that compositional approaches to explaining the rite are unsatisfactory and attempts rather to approach the rite phenomenologically—even if the phenomenon only existed in the imagination of the Priestly writer. With a nuanced understanding of the language used to describe the rite and the correspondence of the Passover-of-Egypt with the Priestly system of Tabernacle sacrifice, the study shows that the four-day detainment of the animal is an intentionally crafted device used to approximate in a pre-Tabernacle environment the mediation between sacred and profane that would later be guarded by priests.
Childhood Experiences and Intimate Partner Violence Among Kenyan Males: Mediation by Self-Esteem and Impulsivity
Authors: Goodman Michael , Wangamati Salome A. , Maranga Florence K. N. , Gitari Stanley , Seidel Sarah , Keiser Philip
Published: July 2019

This study evaluates associations between childhood social environments and current intimate partner conflict tactics in early adulthood. The subsample for this study ( n = 251 men) were participants in a larger community-based study of men’s mental and behavioral health in semirural Kenya. A survey questionnaire was administered by trained interviewers, including validated recall measures from childhood, collective self-esteem and impulsivity, and the conflict tactics scale short form. Analyses utilized regression and mediation methods. The recall measures evaluated the degree of relational warmth and safety recalled from early childhood and forms of abuse, neglect and dysfunction present in the childhood home. Collective self-esteem assessed the perceived value of one’s social groups and one’s value as a member of these groups. Impulsivity measured the propensity to act without thinking. The conflict tactics scale evaluates the presence and frequency of specific behaviors following intimate partner conflict, which lead to two factors—negotiation-based tactics and violence tactics. More early memories of relational warmth, responsiveness, and safety during childhood predict fewer violent intimate conflict tactics. More adverse childhood experiences predict more violent conflict tactics and fewer negotiation-based conflict tactics. Self-esteem and impulsivity mediated associations between recalled childhood experiences and conflict tactics. Further research is required to explore other predisposing factors, psychological processes, and cultural and social norms surrounding the use of violent and nonviolent intimate partner conflict resolution by young men in Sub-Saharan Africa. Violence prevention strategies and policies should explicitly link intimate partner violence prevention with prevention of violence against boys. Interventions should recognize men who perpetrate intimate partner violence are more likely victims of violent childhoods than men who do not perpetrate intimate partner violence. Promoting collective self-esteem and reducing impulsivity among young men may reduce violence against women.
Circumstantial Powers of “Special Fire Police” in Pennsylvania: Statutory Consequences and Recommendations
Authors: Attwood Wesley R. , Sneath Melissa , Thacik John G.
Published: July 2019

Volunteer police have been an instrumental part of Western policing since the inception of the concept of police. The Commonwealth of Pennsylvania utilizes volunteer police under the title of “Special Fire Police.” Described as “firemen cloaked with police powers” in corresponding case law, these volunteers are statutorily provided with full powers to regulate traffic and keep crowds under control at any fire or emergency and to exercise other police powers which are necessary to prevent interference with the work of firemen. Although these volunteers have been in use for more than 50 years, the other police powers they are granted by law have remained largely undefined. This research will examine the current statutory and case law relevant to special fire police as well as those relevant to general Pennsylvania police powers to demonstrate the circumstantially defined police powers that could be adopted based on interpretation.
Perspective-Taking Interventions for Intergenerational Caregivers of Alzheimer’s Diseases: A Randomized Controlled Trial
Authors: Au Alma , Lai Daniel W. L. , Biggs Simon , Cheng Sheung-Tak , Haapala-Biggs Irja , Chow Amy , Gallagher-Thompson Dolores
Published: July 2019

Purpose:

The present study examined the effects of perspective-taking (PT) intervention in the context of intergenerational caregiving.

Method:

Seventy-two adult child caregivers of persons living with Alzheimer’s disease (AD) were randomized into two 8-week interventions: (1) connecting through caregiving (CTC: 37 participants) with intergenerational PT reappraisals and (2) basic skill building (BSB: 35 participants). The CTC intervention focused on PT reappraisals aiming to promote balance between self-care and caring of others: (1) connecting with self through enhancing self-awareness, (2) connecting with the care recipient through empathetic understanding, and (3) connecting with others who can help.

Results:

As compared to the BSB group, the CTC group reported significantly higher increase in the level of life satisfaction and also greater reductions in depressive symptoms and burden. PT was found to mediate between intervention effects and change in life satisfaction.

Discussion:

The results provided evidence for the efficacy of the CTC program in enhancing the well-being of AD caregivers.
Social Context in Development Communication: Reflecting on Gender and Information and Communication Technologies for Development in Ghana
Authors: Steeves H. Leslie , Kwami Janet D.
Published: July 2019

This essay, an example of work that builds on Dr. Ascroft’s lessons, reports collaborative research on information and communication technologies for development (ICT4D) in Ghana. We highlight two parallel dialogues—on ICT and on gender—that have been advanced globally. New ICTs are prone to the same biases as the older ICTs. Further, the dialogue on ICTs may use the rhetoric of inclusivity; but in practice, women and girls remain at the margins of decision-making and implementation. This research addresses the promise of new ICTs and the need to account for gender roles. We summarize the major events that helped spark global and regional attention to ICT4D, as well as Ghana’s initiatives in relation to these events. We include critiques and initiatives resistant to facets of ICT4D, emphasizing gender critiques.
Don’t hurt my outgroup friend: A multifaceted form of imagined contact promotes intentions to counteract bullying

Published: July 2019

A growing body of research has shown that imagined intergroup contact can improve outgroup attitudes. The aim of the present study was to examine the effectiveness of a multifaceted form of imagined contact in counteracting bullying in school children, and additionally to test the underlying processes of this effect. Two hundred and fifteen Italian elementary school children took part in a 3-week intervention, where they were asked to imagine a scenario in which they become friends with an unknown disabled child, interact in various social settings, and react to forms of discrimination toward the newly acquired friend. After each session, they discussed collectively what they had imagined. The dependent measures were administered 1 week after the last session. Results revealed that inclusion of an outgroup member in the self mediated the effect of imagined contact on intentions to counteract social exclusion and bullying of disabled children, as well as helping intentions. Imagined contact also promoted greater willingness for outgroup contact via more positive outgroup attitudes and empathy. Our findings are important in delineating new forms of imagined contact, and understanding ways to promote behaviors that defend victims of social exclusion and bullying in school environments.
Tinder’s lesbian digital imaginary: Investigating (im)permeable boundaries of sexual identity on a popular dating app
Authors: Ferris Lindsay , Duguay Stefanie
Published: July 2019

Dating apps have received rapid uptake, with Tinder as one of the most popular apps in the heterosexual market. However, little research has investigated the experiences of women seeking women (WSW) on this app. This article combines two interview studies of WSW in Australia, Canada, and the United Kingdom to investigate their self-presentations of sexual identity on Tinder. By configuring settings to “seeking women,” participants perceived they were entering a space conducive to finding WSW. However, men, couples, and heterosexual women permeated this space, heightening the need for participants to signal non-heterosexual identity. Their signals fused references to lesbian and queer culture with Tinder’s infrastructure to evoke a digital imaginary, as a routinized set of practices imagined to resonate with a shared community. Although signals within this digital imaginary were sometimes playful and ambiguous, their default toward a recognizable lesbian identity often rendered other sexual or gender identities invisible.
An online anomaly recognition and early warning model for dam safety monitoring data

Published: July 2019

Anomaly recognition and early warning of monitoring data are of great significance in the field of modern dam safety management. Multidimensional least-squares regression model with the Pauta criterion is a well-known traditional method, but it is easy to misjudge the normal value and miss the outliers. Thereby, an online robust recognition and early warning model combining robust statistics and confidence interval is proposed to detect outliers. The threshold [Formula: see text] is set based on the derived confidence interval [Formula: see text] and the scale estimator [Formula: see text] (derived from the location M-estimator). Monitoring data obtained from a gravity dam and a rockfill dam were taken as examples to demonstrate the robust recognition and early warning model. The results show that the proposed method can effectively improve the reliability of anomaly recognition and early warnings, which is valuable in engineering applications.
Robotic-Assisted Total Pericardiectomy for Acute Relapsing Pericarditis: A Case Report
Authors: Balkhy Husam H. , Patel Brooke B. , Spiller Robert , Avella-Patino Diego
Published: July 2019

Acute, relapsing pericarditis is an uncommon potential complication of any cardiothoracic intervention. If medical management fails to mitigate recurrent symptoms, robotic total pericardiectomy can be performed as a definitive therapeutic option. A 33-year-old woman had severely symptomatic, persistent pericarditis, which began 3 weeks after pacemaker placement for tachy-brady syndrome. After failure of pharmacologic treatment, a robot-assisted total pericardiectomy was performed with a drastic improvement in symptoms. Considering that this case of pericarditis was inflammatory (nonconstrictive), a radical excisional approach to all the pericardium was undertaken in order to prevent relapse of symptoms. A bilateral endoscopic off-pump robot-assisted approach was used to completely and fully excise both the anterior and posterior pericardium. In conclusion, we present a case of acute relapsing pericarditis in a very symptomatic patient who failed medical therapy and underwent a robotic totally endoscopic radical pericardiectomy with excellent results. We believe that this technique allows for total pericardiectomy using the least invasive approach and should be considered in the management of this rare but potentially debilitating condition.
A comparison of factors determining the transition to postsecondary education in Toronto and Chicago
Authors: Robson Karen , Anisef Paul , Brown Robert S. , Nagaoka Jenny
Published: July 2019

We examine how race, sex and poverty contribute to the likelihood of attending two- and four-year colleges in Chicago and Toronto. In each city, we use longitudinal data on high school students and their postsecondary trajectories in order to explore how race and sex may impact differentially upon their educational pathways. Our analyses are informed by an intersectionality perspective, wherein we understand that life chances are shaped by the various traits and identities that individuals possess. In Toronto, Black males are less likely than all other groups to attend four-year colleges. We also find that two-year colleges appear to fulfill a different role in Toronto than they do in Chicago; that is, serving populations who may have been tracked into non-academic course selections in high school. We contextualize our findings within the very different political, cultural, and historical contexts of Ontario and Illinois.
Lack of Araceae in Young Forests Highlights the Importance of Mature Forest Conservation
Authors: Fernandez Barrancos Estefania Pilar , Reid J. Leighton , Hall Jefferson S.
Published: July 2019

We compared Araceae abundance among mature forests, secondary forests, and plantations (8–14 years) in central Panama. Araceae colonization was virtually nonexistent in secondary forests and plantations. Low humidity, relatively short forest stature, and time could drive this absence. These results highlight the conservation value of forests containing intact populations of Araceae.

The Adolescent Distress-Eustress Scale: Development and Validation
Authors: Branson Victoria , Dry Matthew J. , Palmer Edward , Turnbull Deborah
Published: July 2019

Lay definitions tend to conceptualize stress as negative, undesirable, and maladaptive. However, contemporary stress models emphasize the differentiation between negative and positive stress responses, known as distress and eustress. Despite prominent theoretical conceptualisations accepting the existence of eustress, the vast majority of stress measures tend to focus exclusively on the distress response. The current study introduces the Adolescent Distress-Eustress Scale (ADES) which holistically captures both aspects of the stress response, bridging the gap between theory and measurement and counteracting the typically negatively focused approach to stress research. The ADES was systematically developed and tested in a socio-educationally diverse sample of 981 adolescents ( Mage = 15.19, 50.62% female). The finalized self-report scale consists of two 5-item subscales, individually indexing distress and eustress. Initial psychometric properties of the ADES are promising, and the scale has the potential to meet the needs of researchers, schools, and organizations.

Published: July 2019

Early care and education (ECE) providers and parents can facilitate physical activity (PA) and reduce screen time in preschoolers. Input from caregivers on barriers and facilitators of PA and screen time is needed to comprehensively address these behaviors and promote children’s health. Four focus groups (3 parent and 1 ECE provider) were conducted. Thematic analysis was performed to identify themes and subthemes. Twenty-eight caregivers (21 parents and 7 ECE providers) participated. Caregivers reported responsibility for modeling and shaping children’s PA and screen time. Parents felt that a busy lifestyle was a PA barrier and encouraged screen time. ECE providers were concerned about certain environmental influences on PA. The groups differed in their view of screen time as either entertainment (parents) or educational (providers). Both types of caregivers were unaware of PA or screen time guidelines. Investigation into opportunities to utilize screen time to serve priorities of both caregivers and promote child PA are needed.
Bumbling, Stumbling, Fumbling: Weakness, Steppage Gait, and Facial Droop in a 3-Year-Old Male
Authors: Whelan Aviva J. , Tolaymat Abdullah , Rainey Shane C.
Published: July 2019

A previously healthy, unimmunized, 3-year-old Caucasian boy presented to the emergency department with right-sided facial droop, clumsiness, and intermittent bilateral hip pain. Two weeks ago, he had 24 hours of self-resolving rhinorrhea and fever. Examination was significant for right facial nerve palsy, lower extremity pain, areflexia of his right lower extremity, and diminished reflexes of his left lower extremity. He was admitted for urgent magnetic resonance imaging of the brain. Cerebrospinal fluid (CSF) protein was 85 mg/dL with elevated albumin and immunoglobulin, and CSF white blood cell was 3 cells/mm3. Serum Mycoplasma immunoglobulin (Ig) M and IgG were elevated. There was concern for Guillain-Barré syndrome (GBS). He was started on intravenous IG (IVIG) and was treated for presumed Mycoplasma infection. Weakness and gait disturbances in a child can present the clinician with a diagnostic challenge. Gait disturbance may indicate a neurological lesion anywhere from the central nervous system to the peripheral nerves, neuromuscular junction, or muscle. In the present case, the combination of peripheral facial palsy, presumed neuropathic pain, gait difficulties, and areflexia in the setting of an antecedent respiratory illness were suggestive of GBS. The cornerstone treatments involve hospitalization to facilitate continuous monitoring for serious sequelae, such as acute respiratory failure and cardiac dysrhythmia, followed by immunotherapy with IVIG or plasma exchange. Gait disturbance and weakness in a child is a diagnostic challenge. GBS is the most common cause of acute paralysis in the Western world and should remain high on the clinician’s differential diagnosis. However, patients with GBS may also present nonclassically with extremity pain and cranial nerve palsies.

Anesthetic management of the adult patient with a Fontan circulation is complex and requires understanding of the specific physiology of the individual patient. Long-term survival in this cohort has increased to the point where patients are presenting for noncardiac surgery related to degenerative diseases of aging. We describe the perioperative management of a patient with a Fontan circulation undergoing total hip arthroplasty using combined spinal–epidural anesthesia and discuss the issues requiring special consideration for this surgical procedure in this group of patients.
Defending Local Autonomy and Facing Cultural Trauma: A Nahua Order against Idolatry, Tlaxcala, 1543
Authors: Olko Justyna , Brylak Agnieszka
Published: July 2019

On February 12, 1543, in the city of Tlaxcala an indigenous governor, don Valeriano Castañeda, issued an order putting local alguaciles in charge of overseeing possible idolatrous or sinful acts in several localities. This document, housed in the Archivo Histórico del Estado de Tlaxcala, is probably the earliest dated Nahuatl document known to date. This essay, apart from transcribing and translating this brief, important testimony that deals with the extirpation of old beliefs, sets the text in the wider social, political, and religious context of the period immediately after a series of violent inquisitional acts in the mid- and late 1520s and late 1530s. The issuing of such an order by a member of the Tlaxcalan political elite is a clear example of a carefully implemented act of long-term indigenous agency, aimed at constructing and extending the domains of native power following the cultural trauma of the conquest and Christianization.
Stealing Words, Transplanting Images
Authors: Liu Yu-jen
Published: July 2019

This article explores how the category “Chinese art” was articulated and consolidated in the early twentieth century by focusing on Stephen Bushell's Chinese Art, the first book in English defined in terms of this category. Bushell's monograph highlights the intercultural character of the category, which was transformed in its content and cultural significance, when ostensibly the same authentic knowledge, articulated in verbal and visual representations, was moved from China to Europe and back again. The article starts by examining how Bushell's insider knowledge of Chinese art was transformed to fit the institutional setting of the Victoria and Albert Museum. It then explores how the authoritative knowledge of Chinese art communicated in Bushell's book was appropriated in China by the journal Guocui xuebao 國粹學報 (Journal of National Essence) in the context of attempts to revive national culture. Both cases involved hitherto unnoticed repetitions of text and images. By analyzing the mechanism informing these repetitions, this article reveals the entangled history behind the distinctive articulations of “Chinese art” in Britain and in China. Moreover, the analysis shows how the same elements, whether words or pictures, acquired a substantially different significance as they moved between cultures. This is exemplified by the formulation of the newly emergent classifying category Zhongguo meishupin 中國美術品 (“Chinese art objects”) in Guocui xuebao.
Curating A Third Gender: Beautiful Youths in Japanese Prints
Authors: Ikeda Asato
Published: July 2019

Should we discuss practices around sex and sexuality in early modern Japan as a distinct, foreign phenomenon entirely unique to the period and culture, or can we somehow draw a genealogy and create a trans-historical narrative that ends with today's LGBTQ+ culture? These questions were central to the process of organizing the exhibition A Third Gender: Beautiful Youths in Japanese Prints at the Royal Ontario Museum (ROM) in Toronto in 2016. The exhibition focused on visual representations of male youths, called wakashu in Japanese, who were the object of sexual desire for both women and adult men in Edo-era Japan. Presented in the form of an exhibition, the project necessitated engaging the past with the present and the general public with scholarship. In this short reflection essay, the author and curator explains how the Third Gender project approached the question of Edo-era Japan's trans-historicity.
Relative Effort while Walking Is Higher among Women Who Are Obese, and Older Women
Authors: KOUSHYAR HODA , ANDERSON DENNIS E. , NUSSBAUM MAURY A. , MADIGAN MICHAEL L.
Published: July 2019

Purpose

Individuals who are obese, and older individuals, exhibit gait alterations that may result, in part, from walking with greater effort relative to their maximum strength capacity. The goal of this study was to investigate obesity-related and age-related differences in relative effort during gait.

Methods

Four groups of women completed the study, including 10 younger healthy-weight, 10 younger obese, 10 older healthy-weight, and 9 older obese women. The protocol included strength measurements at the hip, knee, and ankle in both flexion and extension, and gait trials under self-selected and constrained (1.5 m·s−1 gait speed and 0.65-m step length) conditions. Relative effort was calculated as the ratio of joint torques during gait, and strength from a subject-specific model that predicted strength as a function of joint angle.

Results

Relative effort during self-selected gait was higher among women who were obese in knee extension (P = 0.028) and ankle plantar flexion (P = 0.013). Although both joint torques and strength were higher among women who were obese, these increases in relative effort were attributed to greater obesity-related increases in joint torques than strength. Relative effort was also higher among older women in hip flexion (P < 0.001) and knee extension (P = 0.008), and attributed to age-related strength loss. Results were generally similar between self-selected and constrained gait, indicating the greater relative effort among women who were obese and older women was not attributed to differences in gait spatiotemporal characteristics.

Conclusions

Women who were obese, as well as older women, walk with greater relative effort. These results may help explain the compromised walking ability among these individuals.
Behavioural Forensics: Revelations from CNX Nifty Analysis
Authors: Ramesh Golait Pooja
Published: July 2019

Economic growth and sustainable development in financial markets are only possible when the firms show robustness and stability through the ethical way of business. However, it has been observed that certain firms take incorrect measures while running their business. This work attempts to detect threads of possible financial frauds by Didier Sornette’s drawdown approach. Select CNX Nifty 50 Mid Cap stocks are shown here as samples. Drawdown approach identifies the breakpoints and clearly detects the dates and could be linked to the anchoring and herding behaviour in certain cases. Apart from that, other financial or strategic events could be linked as well. Qualified institutional buyers and large institutional investors can use this method as a corporate governance crosscheck, from an entirely different standpoint.
The Causal Relationship between the Stock Indices of Western Bloc Countries: A Case on Belgium and France
Authors: Verma Anjali , Joseph T Treesa
Published: July 2019

The paper aims at finding reciprocity among two Western European Bloc indices CAC40 and BEL20. CAC40 is a French index which has been in existence since 1986 and BEL20 is a Belgian index whose calculation started four years later. A Granger Causality Test has been performed to check for causality relationships among both the indices. The dataset taken comprises logarithmic close prices on which Bivariate Granger Causality has been performed. The dataset spans for 20 years from 2000 to 2018. The study found the younger index BEL20 to be the driver index and CAC40 as the driven index. Thus, the conclusion drawn is that the performance of CAC40 depends on BEL20 most of the time.
Credit Pit Detection in Subordinate Securities: A French Perspective
Authors: Jain Sfoorti
Published: July 2019

The purpose of this research is to prepare a predictive model for identifying credit crisis using an artificial neural network. The paper also aims to find out the driver and driven relationship between various financial instruments like CDS, FRA, IRS, and the Volatility index (VCAC) and government securities for France. The model, thus, is directed towards finding a threshold for credit pit events and linking various events corresponding to that dates where the threshold is breached to validate the accuracy and usefulness of the model. From the research, it is found that for France, the CDS-FRA-VCAC model derives the threshold for VCAC to indicate the probability of credit crisis or financial market crash. It is also found that sovereign bonds have a huge impact on France economy including various derivatives. This is probably why the Eurozone debt crisis impacted France much more than the 2008 financial crash.
The case for using implanted ports
Authors: Hodson Jane
Published: July 2019

Uses of central venous access devices (CVADs) include the administration of vital fluids and medications. Implanted ports are a type of CVAD that is used when long-term vascular access is required. The device is discreet and associated with a low risk of catheter-related bloodstream infection. This article describes the different types and components of ports and how to select them. It explains how to insert ports, and provides guidance on accessing and de-accessing them
The benefits of a hospital palliative care team

Published: July 2019

Aim:

To investigate the association between a hospital palliative care unit assessment and hospital outcome.

Methods:

This was a prospective cohort study. Data were assessed from all patients treated and followed by the hospital palliative care team (HPCT) from November 2016 until December 2017.

Results:

The mean age of the 588 patients was 73.15±13.6 years. All of the patients included in the study were referred to palliative care. A large proportion of patients were affected by cancer, 69.7% (410), while 30.3% (178) were affected by an advanced chronic illness. The three most frequent cancers were: gastrointestinal (n=81, 19.8%), gynaecological (n=66, 16.1%) and lung (n=63, 15.4%); the three most frequent chronic advanced diseases were: advanced dementia (n=45, 25.3%), severe ischaemic/haemorrhagic stroke (n=36, 20.2%) and severe heart failure (n=25, 15.3%). The majority of patients were in clinical wards (n=476, 81.0%) and the average length of stay was 22.9 days. Hospital outcome trends were evaluated in terms of length of stay and number of deaths that occurred in the hospital. In particular, length of stay decreased from 25.8 days to 18.1 days, hospital death from 13 to 0 during the time that the HPCT assessed patients for an appropriate discharge.

Conclusion:

The HPCT is an effective means of managing patients affected by severe illness, reducing the number of deaths that occur within the hospital, long periods of hospitalisation and instances of readmission. However, further studies are required to fully assess the impact of an HPCT on hospital outcomes.

Purpose

The purpose of the study was to evaluate the reliability, review differences and assess patient satisfaction of electronic patient-reported outcome measures (PROMs) compared with paper PROMs.

Methods

Participants between 12 and 19 years of age with a knee-related primary complaint were randomized into two groups. Group 1 completed paper PROMs followed by electronic, while Group 2 received the electronic followed by paper. PROMs included the Pediatric International Knee Documentation Committee (Pedi-IKDC), Hospital for Special Surgery (HSS) Pediatric Functional Activity Brief Scale (HSS Pedi-FABS), Tegner Activity Level Scale, Visual Analogue Scale (VAS), PedsQL Teen and a satisfaction survey.

Results

In all, 87 participants were enrolled with one excluded due to incomplete PROMs. Of the 86 participants, 54 were female and 32 were male with an average age of 14.3 years (12 to 18). A high degree of reliability was found when comparing the paper and electronic versions of the Pedi-IKDC (0.946; p < 0.001), HSS Pedi-FABS (0.923; p < 0.001), PedsQL Teen (0.894; p < 0.001), Tegner Activity Level Scale before injury (0.848; p < 0.001) and the Tegner Activity Level Scale after (0.930; p < 0.001). Differences were noted between the VAS scores, with paper scores being significantly higher than electronic (5.3 versus 4.6; p < 0.001). While not significant, a trend was noted in which electronic PROMs took, overall, less time than paper (10.0 mins versus 11.2 mins; p = 0.096). Of all participants, 69.8% preferred the electronic PROMs, 67.4% felt they were faster, 93.0% stated they would complete forms at home prior to appointments and 91.8% were not concerned about the safety/privacy of electronic forms.

Conclusion

PROMs captured electronically were reliable when compared with paper. Electronic PROMs may be quicker, will not require manual scoring and are preferred by patients.
