Published: June 2019

Anolis nigropunctatus is herein synonymized with Anolis jacare. We redescribe A. jacare on the basis of 40 specimens from Trujillo, Mérida and Táchira states in Venezuela as well as from Norte De Santander in Colombia, thus greatly expanding the known distribution of the species. We describe A. anatoloros n. sp., a new species of Anolis lizard from the Andes of Venezuela that is closely related to A. jacare. This species inhabits the premontane wet forests of the eastern Andean piedmont in the states of Barinas, Portuguesa and Trujillo and is likely a vicariant of A. jacare. The two species differ in dewlap and body coloration as well as in certain details of the head squamation. A. anatoloros sp. nov. is characterized by a turquoise green dewlap, large scales bordering the inner margin of the supraciliar series, usually a higher number of suboculars in contact with supralabials and large scales around the interparietal.
On some species of Chone Krøyer, 1856 (Polychaeta: Sabellidae) from world-wide localities
Authors: TOVAR-HERNÁNDEZ MARÍA ANA
Published: June 2019

The present study deals with the revision of type and non-type material from species of Chone Krøyer, 1856 (Polychaeta: Sabellidae) that have been described from world-wide isolated localities. Chone australiensis Hartmann-Schröder, 1979, C. fauveli McIntosh, 1916, C. kroyerii Sars, 1862, C. letterstedti (Kinberg, 1867), C. murmanica Lukasch, 1910, C. normani McIntosh, 1916, C. paracincta Hartmann-Schröder, 1962, and C. rosea Hartmann-Schröder, 1965, are redescribed. Two additional forms are recognized as independent taxa, referred to as Chone sp. “Aleutian Islands” and Chone sp. “British Virgin Islands”. These species are informally described since few specimens are available; however, they are included here in order to facilitate and encourage further research. Sabella costulata Grube, 1877, is transferred to Chone. Chone suspecta Krøyer, 1856, is synonymized with Chone infundibuliformis Krøyer, 1856; the name infundibuliformis has priority over suspecta. Chone murmanica oculata Annenkova, 1952, deserves specific status. Chone eniwetokensis (Reish, 1968) is returned to the original genus (Euchone). Chone perseyi Zenkewitsch, 1925, and Chone rubrocincta Sars, 1862, are transferred to Euchone. Chone reayi McIntosh, 1916, is transferred to Jasmineira Langerhans, 1880. Differences and similarities with members of Euchone Malmgren, 1866, and close genera are discussed.
Principles for a names-based cyberinfrastructure to serve all of biology
Authors: PATTERSON DAVID J. , FAULWETTER SARAH , SHIPUNOV ALEXEY
Published: June 2019

The rapidly growing amount of biological data on the internet and the increasing need for large-scale analyses mandate improvements to the management of taxon-centric information. This information, traditionally managed by taxonomists, is now transforming into a web-based infrastructure. The complexity and narrative quality of the biological sciences require an information management framework that is sensitive to the scale, richness, character, and heterogeneity of the discipline. Given that the names of organisms offer us a nearly universal system for indexing biological data objects, a names-based cyberinfrastructure has the capacity to index the totality of available biological information and to aggregate taxon-centric data over a broad scale. In order to serve its role, this infrastructure should incorporate thirteen principles that are proposed here.

Authors: GATTOLLIAT JEAN-LUC , HUGHES SAMANTHA J. , MONAGHAN MICHAEL T. , SARTORI MICHEL
Published: June 2019

A comprehensive revision of the mayflies (Ephemeroptera) inhabiting the island of Madeira (Portugal) is presented, based on newly collected specimens and DNA sequence analysis. Disregarding a report of a single Centroptilum female subimago that is very likely a misidentification, the Madeira mayfly fauna encompasses three species, all belonging to the Baetidae. Previous reports of the continental species Cloeon dipterum Linnaeus, 1758 are erroneous, as all examined specimens belong to the new species Cloeon peregrinator n.sp. Gattolliat and Sartori. Baetis atlanticus Soldán & Godunko, 2006 is by far the most common and abundant species on the island. A second new species, B. enigmaticus n.sp. Gattolliat and Sartori is established for larvae presenting rheophilous adaptations similar to those of B. pseudorhodani Müller-Liebenau, 1971 from the Canary Islands.

P. brachialis (n. comb.) known only from Brazil is redescribed and recorded for the first time from Argentina. Phylogenetic affinities of this new genus are discussed. Dorsal photographs of the species, illustrations of male genitalia, and a key to the species are provided.
Further division of Alona Baird, 1843: separation and position of Coronatella Dybowski & Grochowski and Ovalona gen.n. (Crustacea: Cladocera)
Authors: VAN DAMME KAY , DUMONT HENRI J.
Published: June 2019

We investigate morphology and taxonomic rank of several Alona species related to A. rectangula Sars, 1861. Despite high morphological intraspecific variability, a number of synapomorphies shows that taxa related to A. rectangula are sufficiently different in external and internal morphology from “true” Alona Baird, 1843. These are removed from Alona into separate genera. The rare West-African A. holdeni Green 1962 is redescribed and we describe a new species from North Africa, Arabia and islands in the Western Indian Ocean. We reinstate the name Coronatella Dybowski & Grochowski to receive A. rectangula, A. holdeni, and a new species, C. anemae. Sharing several synapomorphies, the subantarctic species A. weinecki Studer appears related to A. meridionalis Sinev, 2006. We assign them to Ovalona gen.n., similar in morphology to Coronatella, but with less limb reductions. At a higher level, we discuss morphology and distribution of both genera and of the similar A. elegans-group. To situate Coronatella within the subfamily, we introduce a “Coronatella-branch”, a group of medium-sized Aloninae with limb reductions, comprising Coronatella, Leberis, Celsinotum, A. dentifera, A. monacantha and possibly Karualona and A. verrucosa-group, in comparison with a “Hexalonabranch” and Alona s.str. Adaptations to life in temporary pools and salinity tolerance may have played an important role in separation and radiation of a Coronatella-branch.

A new species of feather mite: Timalinyssus Mironov, 2001 (Astigmata: Pteronyssidae) from Garrulax canorus canorus (Linnaeus) (Passeriformes: Timaliidae) in China
Authors: WANG ZI-YING , WANG JIN-JUN
Published: June 2019

Many regard the Pteronyssidae as a subfamily of Avenzoariidae Oudemans, 1905, but Mironov (2001) recently recognized the group as a family, based on the unique character of a ventral membrane on tarsi I, and other distinguishing features of the Pteronyssinae Oudemans, 1941 (vide: Gaud & Atyeo 1996) and the specificity their host associations. To date, 140 species in 23 genera are described (Mironov 2001, 2005). The genus Timalinyssus was established by Mironov (2001) to accommodate two species collected from babblers (Passeriformes: Timaliidae). It is closely related to Mouchetia Gaud but differs in the following characters: prodorsal shield is fused with the scapular shields, c2 setiform and short in both sexes; tarsi III are cone-like with acute apex in male; opisthosomal lobes are long and separated by narrow terminal cleft in female (Gaud & Atyeo 1996; Mironov 2001).

Alphaea alfreda, a new species from China and Myanmar (Lepidoptera, Erebidae, Arctiinae
Authors: VOLYNKIN ANTON V. , SALDAITIS AIDAS
Published: June 2019

The arctiine genus Alphaea Walker, 1855 is distributed in North and North East India, Nepal, southern China and northern Indochina. The genus was recently reviewed by Dubatolov & Kishida (2005). It is subdivided into three subgenera, Alphaea, Flavalphaea Dubatolov & Kishida, 2005 and Nayaca Moore, 1979 and includes 10 valid species. During a lepidopterological expedition to the north-western part of China’s Yunnan Province in May of 2018, an undetermined species of Alphaea was collected. The Chinese specimens have the wing pattern very similar to that of A. (Flavalphaea) khasiana (Rothschild, 1910), but red and black abdomen (that is orange and black in A. khasiana).

Authors: PÉREZ-HERNÁNDEZ CISTEIL X. , ZARAGOZA-CABALLERO SANTIAGO , ROMO-GALICIA ALBERTO
Published: June 2019

A checklist, distribution records, and the updated nomenclature for Mexican Lycidae are presented here. Two subfamilies, 7 tribes, 24 genera, 2 subgenera and 168 valid species of Lycidae (Coleoptera: Elateroidea) taxa were recorded from Mexico, including 111 (66%) endemic species. For each species, synonyms used in Mexico and geographical distribution in Mexican states were provided. The highest species richness was recorded in Veracruz, Chiapas and Oaxaca, while Aguascalientes and the Yucatan Peninsula states had very few records of Lycidae species probably due to the lack of fieldwork. In the Nearctic region, Lycidae diversity comprised 4 tribes, 10 genera and 27 species; in Mexican transition zone, 5 tribes, 17 genera and 100 species; and in Neotropical region, 7 tribes, 19 genera and 94 species. The highest species richness of Lycidae was recorded in the Veracruzan, Transmexican Volcanic Belt and Chiapas Highlands provinces. Although there has been a relevant rise in taxonomical work concerning Mexican lycid fauna in the last two decades, it is still necessary to continue in systematic, ecological, and biogeographical studies of the family in Mexico, especially in scarcely studied regions.

The Effect of QPF on Real-Time Deterministic Hydrologic Forecast Uncertainty
Authors: Adams Thomas E. , Dymond Randel
Published: June 2019

The use of quantitative precipitation forecast (QPF) in hydrologic forecasting is commonplace, but QPF is subject to considerable error. When QPF is included as a model forcing in the hydrological forecast process, significant error propagates through the hydrologic predictions. Two questions arise: 1) are the resulting observed hydrologic forecast errors sufficiently large to suggest the use of zero QPF in the forecast process, and 2) if the use of nonzero QPF is indicated, how many periods (hours) of QPF (1, 6, 12, …, 72 h) should be used? Also, do forecast conditions exist under which the use of QPF should be different? This study presents results from two real-time hydrologic forecast experiments, focused on the NOAA/NWS Ohio River Forecast Center (OHRFC). The experiments rely on forecasts from subbasins at 39 forecast point locations, ranging in drainage area, geographic location within the Ohio River Valley, and watershed response time. Results from an experiment, spanning all flow ranges, for the 10 August 2007–31 August 2009 period, show that nonzero QPF produces smaller hydrologic forecast error than zero QPF. A second experiment, 23 January 2009–15 September 2010, suggests that QPF should be limited to 6–12-h duration for flood forecasts. Beyond 12 h, hydrologic forecast error increases substantially across all forecast ranges, but errors are much larger for flood forecasts. Increased durations of QPF produce smaller forecast error than shorter QPF durations only for nonflood forecasts. Experimental results are shown to be consistent with NWS April 2001–October 2016 forecast verification statistics for the OHRFC.
Which Phish Is on the Hook? Phishing Vulnerability for Older Versus Younger Adults
Authors: Sarno Dawn M. , Lewis Joanna E. , Bohil Corey J. , Neider Mark B.
Published: June 2019

Objective

To determine if there are age-related differences in phishing vulnerability and if those differences exist under various task conditions (e.g., framing and time pressure).

Background

Previous research suggests that older adults may be a vulnerable population to phishing attacks. Most research exploring age differences has used limiting designs, including retrospective self-report measures and restricted email sets.

Method

The present studies explored how older and younger adults classify a diverse sample of 100 legitimate and phishing emails. In Experiment 1, participants rated the emails as either spam or not spam. Experiment 2 explored how framing would alter the results when participants rated emails as safe or not safe. In Experiment 3, participants performed the same task as Experiment 1, but were put under time pressure.

Results

No age differences were observed in overall classification accuracy across the three experiments, rather all participants exhibited poor performance (20%–30% errors). Older adults took significantly longer to make classifications and were more liberal in classifying emails as spam or not safe. Time pressure seemed to remove this bias but did not influence overall accuracy.

Conclusion

Older adults appear to be more cautious when classifying emails. However, being extra careful may come at the cost of classification speed and does not seem to improve accuracy.

Application

Age demographics should be considered in the implementation of a cyber-training methodology. Younger adults may be less vigilant against cyber threats than initially predicted; older adults might be less prone to deception when given unlimited time to respond.
Low-power design-for-test implementation on phase-locked loop design
Authors: Yadlapati Avinash , Kakarla Hari Kishore
Published: June 2019

Low-power design for test is the need of the hour for any system-on-chip designer. The low-power design techniques have been a major challenge to both the designer as well as the testing engineer. With so many advancements in low-power technology in the phase of register transfer logic design, functional verification, register transfer logic and physical synthesis and physical design. Design for test is not an exception to this. The low-power design-for-test techniques can be applied at various levels of the design-for-test flow as in the scan insertion stage, automatic test pattern generation simulations stage, testing stage, and so on. Some of the reasons for the high-power utilization in the design-for-test phase can be due to the external circuitry being inserted during the design phase and not used in the functional mode. The complete circuit will be active in the test mode only. In this paper, the focus will be primarily on reducing the power during the automatic test pattern generation scan synthesis phase. All the scan flops are connected by a common scan clock with a fixed frequency. The intention of this study is to divide the clock frequency by half and make sure that the power is reduced without affecting any timing violations. Since the scan clock frequency is low, it can be further divided to ensure that power is reduced without affecting the testing process of the chip.
An inductive-capacitive-circuit-based micro-electromechanical system wireless capacitive pressure sensor for avionic applications: Preliminary investigations, theoretical modelling and simulation examination of newly proposed methodology
Authors: Jindal Sumit Kumar , Mahajan Ankush , Raghuwanshi Sanjeev Kumar
Published: June 2019

Pressure is a key unit of measure in aerospace industries. Spontaneous precise measurement of pressure has to be compassed at locations where it is futile and impractical to couple the pressure responsive constituent to the conditional electronics or computational circuit by practicing standard cables and measurements prone to harsh environment. This paper introduces the design of a wireless pressure-monitoring system for aerospace applications in harsh environment. Traditionally, applied pressure deflects a delicate silicon diaphragm, altering the capacitance developed between it and metal electrode firm on a substrate. The LC circuit translates the pressure variation into the LC resonant frequency shift. This change is sensed remotely by virtue of inductance coupling, expelling the compulsion for wire connection rooted telemetry circuits. Novelty of our work rests in the fact that contrary to examining shift in the resonant frequency due to the applied pressure, we have put in effort to maintain resonant shifting equal to zero by varying the capacitance at the observer unit. This will allow pressure variations to be measured directly in terms of the capacitance variation at a fixed resonant frequency, which is 7.92 MHz in our context. According to the application domain (avionics), the proposed sensor structure is designed for functioning in the pressure range between (100 and 1140) mbar. The choice of design values for sensor parameters has been validated. The sensitivity is measured to be 1.746e−17 F/Pa over specified linear range which is shown to match a theoretical estimate realized by mathematical model. An in-depth, step by step derivation of performance parameters to achieve above-stated objective is shown for sensor under study. The results generated are modelled and examined using MATLAB. The analysis conducted dovetail perfectly with the modelled results.

Authors: Nagarjuna T , Lakshmi S , Nehru K
Published: June 2019

This article commenced the real-time education and research podium for characterize wireless networks, analog and digital communications courses with National Instruments Universal Software Radio Peripheral Device (NI USRP 2901) device. The 5G Cellular communications will claim remarkable flexibility from the physical layer. Many research ideas are proposed and compared with the theoretical part but there is a lack of enactment of a system under real-time channel conditions and front-end impairments. In this article, a single-input single-output generalized frequency division multiplexing transceiver is performed with NI USRP 2901, which utilizes radio frequency platform it has the ability to work as the transceiver in the frequency range of 70 MHz to 6 GHz and it also provides multiple input and multiple output support, which is helpful for the implementation of industry-based wireless operation prototypes. The generalized frequency division multiplexing system model is programmed in the LabVIEW software block diagram panel along with USRP configuration utility. In view of field-programmable gate arrays, both programming host handling and continuous preparing can be actualized. This usage enables the clients to assess distinctive generalized frequency division multiplexing performance characteristics, such as total harmonic distortion, signal in noise and distortion (dB), and specific harmonic, transmitted bit stream and received bit stream with error count, bit error rate value, and its graph are plotted. The simulation results show that the generated generalized frequency division multiplexing signal has a total harmonic distortion value of 0.793054 and signal in noise and distortion value of 0.204343. The specific harmonic value is 0.0228768 and the bit error rate value is 0.003125. The generalized frequency division multiplexing signal slightly outperforms the orthogonal frequency division multiplexing signal in terms of real-time transmission signal characteristics such as total harmonic distortion, signal in noise and distortion, bit error rate, power spectrum value, Wigner–Ville distribution value in the two-dimensional array and corresponding graphs are plotted. The proposed system outperforms existing system by a margin of 3% in real-time channel using the USRP 2901 device.

Published: June 2019

Background:

In general populations, consistent data highlight the relationships among violence, HIV risk behavior and depression; however, these patterns are not well understood among female sex workers (FSWs). We examined the relationship between FSWs’ experiences with sexual violence and consistent condom use as a key HIV risk behavior and explored mental health as a potential mediator.

Methods:

In total, 2,165 FSWs were recruited via respondent-driven sampling in Cameroon in 2016. The women answered questions about violence, condom use and mental health.

Results:

Inconsistent condom use with clients was reported by 23.5% of participants (508/2,165). Lifetime sexual violence was prevalent with 33.0% (713/2,163) of participants. Almost 50% (1,067/2,143) of respondents had some level of depression. Sexual violence was significantly associated with inconsistent condom use (adjusted risk ratio (aRR) 1.4, 95% confidence interval (CI) (1.2–1.6)). Of FSWs with no depression, 24.9% (267/1,071) reported sexual violence, versus 56.1% (32/57) of respondents with severe depression ( p < .01). Severe depression significantly increased risk of condomless sex (aRR 1.8, 95% CI (1.3–2.6)); in mediation analysis, both sexual violence and severe depression remained significant predictors of condomless sex (aRR 1.4, 95% CI (1.2, 1.6) and aRR 1.7, 95% CI (1.2–2.4), respectively). Depression did not mediate the relationship between sexual violence and condom use.

Conclusion:

Sexual violence and depression are prevalent and independently associated with condom nonuse with clients among FSWs in Cameroon. Results highlight the need for interventions to address mental health as well as gender-based violence for FSWs.
Trunk Control in Children With Ataxic Cerebral Palsy
Authors: Seyyar Gulce Kallem , Aras Bahar , Aras Ozgen
Published: June 2019

This study aimed to investigate the clinical characteristics of trunk control in children with ataxic cerebral palsy (CP). We included 15 children with ataxic CP with a mean age of 9.46 years ( SD = 1.08 years, 5–17 years) and 15 healthy children with a mean age of 9.06 years ( SD = 0.84 years, 5–13 years). While the small sample size and large age range used here were not ideal for generalizability, they were made necessary by the rarity of this clinical sample. We used the Gross Motor Function Classification System Expanded and Revised (GMFCS-E&R) to classify the children’s functional levels, and we tested trunk control with the Trunk Control Measurement Scale (TCMS). We then used the Gross Motor Function Measurement-88 (GMFM-88) to assess their gross motor functions. We compared the total and subscale scores of the TCMS in healthy children and children with ataxic CP by using the Mann–Whitney U Test. We also analyzed differences between TCMS scores according to the children’s GMFCS levels with the Mann–Whitney U Test and also compared TCMS scores with the GMFM-88 by means of Spearman correlation analysis. Spearman correlation analysis was used to compare the scores of the TCMS with the GMFM-88. Our results showed that healthy children showed significantly higher scores than children with ataxic CP in total and subscale scores of TCMS ( p < .05).There was no significant difference between the TCMS scores in children of different GMFCS levels, but the GMFM-88B subscale was signiﬁcantly correlated with the static sitting balance ( rho = .568, p < .05) and dynamic sitting balance ( rho = .547, p < .05) TCMS subscales and with the TCMS total score ( rho = .590, p < .05). We concluded that trunk control, especially its dynamic aspects, was impaired in children with ataxic CP.
Emotional Intelligence, Job Satisfaction, Emotional Exhaustion, and Subjective Well-Being in High School Athletic Directors
Authors: Lee Ye Hoon , R. Richards K. Andrew , Washhburn Nicholas S.
Published: June 2019

Developing subjective well-being among educational leaders is beneficial for both leaders themselves and students. Evidence has suggested that emotional intelligence has implications for the mental and physical well-being of individuals in leadership positions. This relationship has not, however, been extensively investigated among school administrators, particularly athletic directors, who can influence the lives of student-athletes. Thus, this study sought to examine the relationships among emotional intelligence, job satisfaction, emotional exhaustion, and subjective well-being in high school athletic directors. Participants included 394 U.S. high school athletic directors who completed questionnaires relating to emotional intelligence, job satisfaction, emotional exhaustion, and subjective well-being. The results revealed positive associations between emotional intelligence and subjective well-being and also demonstrated that both job satisfaction and emotional exhaustion mediated the emotional intelligence-subjective well-being relationship. The results highlight the role of emotional intelligence in athletic directors’ subjective well-being and suggest that athletic directors should take measures to increase their emotional intelligence through professional learning opportunities and school support structures.
Adaptive parameter tuning for agent-based modeling and simulation
Authors: Korkmaz Tan Rabia , Bora Şebnem
Published: June 2019

The purpose of this study was to solve the parameter-tuning problem of complex systems modeled in an agent-based modeling and simulation environment. As a good set of parameters is necessary to demonstrate the target behavior in a realistic way, modeling a complex system constitutes an optimization problem that must be solved for systems with large parameter spaces. This study presents a three-step hybrid parameter-tuning approach for agent-based models and simulations. In the first step, the problem is defined; in the second step, a parameter-tuning process is performed using the following meta-heuristic algorithms: the Genetic Algorithm, the Firefly Algorithm, the Particle Swarm Optimization algorithm, and the Artificial Bee Colony algorithm. The critical parameters of the meta-heuristic algorithms used in the second step are tuned using the adaptive parameter-tuning method. Thus, new meta-heuristic algorithms are developed, namely, the Adaptive Genetic Algorithm, the Adaptive Firefly Algorithm, the Adaptive Particle Swarm Optimization algorithm, and the Adaptive Artificial Bee Colony algorithm. In the third step, the control phase, the algorithm parameters obtained via the adaptive parameter-tuning method and the parameter values of the model obtained from the meta-heuristic algorithms are manually provided to the developed tool performing the parameter-tuning process and they are tested. The best results are achieved when the meta-heuristic algorithms that were successful in the optimization process are used with their critical parameters adjusted for optimum results. The proposed approach is tested by using the Predator–Prey model, the Eight Queens model, and the Flow Zombies model, and the results are compared.
Setting the stage: liturgy and theatre
Authors: Clammer Tom , Clammer Emma
Published: June 2019

At the outset it is recognized that theatre is diverse and constantly evolving and therefore elusive in definition. Liturgical worship, similarly, presents itself in many forms. The constraints of an article-length exploration necessarily lead us to focus on liturgical worship in a cathedral context, and most of the comparisons with theatre focus on it in its mainstream Western form. This article does not pretend to be exhaustive, but raises some parallels and contrasts which we offer to the wider Church as a starting point for further exploration.
A Wesleyan holiness theology and language world: a demonstration of holiness theology as a religious linguistic characteristic in the light of speech act theory
Authors: Cho Anna
Published: June 2019

Holiness as the subject of Wesleyan holiness theology is not only God’s divine language but also an experiential language of humans. Despite this fact, research that considers the religious linguistic features of holiness theology as they relate to its meaning and effects in the real lives of believers seems to have been neglected. Thus, this article proposes to examine the language of holiness in terms of Wesleyan holiness theory by means of speech act theory. First, this approach solves the problem of overcoming the proposition principle of holiness theology. Second, it shows an understanding of the linguistic hermeneutics of the work of the Holy Spirit in believers. And finally, it presents the ways in which the religious divine language of holiness can be described as an ethical language characteristic of human experiential language.
The obesity epidemic and the metropolitan-scale built environment: Examining the health effects of polycentric development
Authors: Yang Jiawen , Zhou Peiling
Published: June 2019

Existing research on how the built environment affects physical activity and obesity has mainly focused on neighbourhood-scale features, such as land use mix, street connectivity and density. This research hypothesises that metropolitan-scale built-environment characteristics, such as polycentricity, should also play an important role. The impacts of the metropolitan built environment on individual travel behaviour will further affect how individuals allocate their time for sedentary activities, moderate physical activities and vigorous exercise, which in turn should affect individual weight status. This research uses the American Time Use Survey from 2003 to 2007 and spatial statistical polycentricity metrics for hypothesis testing. A multi-level path analysis reveals that living in a relatively polycentric region is significantly associated with a lower obesity probability with multiple paths: individuals living in relatively polycentric regions tend to spend less time on sedentary activities and more time on moderate-to-vigorous physical activities, which increases their daily energy expenditure; beyond the linkage to energy expenditure, living in a relatively polycentric region is directly associated with a lower obesity probability, which suggests other ways that the polycentric structure influences individual weight status. This research furthers the literature by examining how the formats of metropolitan spatial development are relevant to broader issues of individual lifestyles and public health. The results suggest that regionwide efforts to cultivate suburban centres of increased density could lead to significant public health benefits.

After two decades of debates, the law governing surrogacy in India was passed during the winter session of the Parliament, and Surrogacy (Regulation) Act 2018 came into existence. This new law prohibits commercial surrogacy on grounds of preventing exploitation of surrogate women and to protect the rights of children born out of surrogacy. The Act allows only ‘ethical altruistic’ surrogacy. This commentary criticises the false premise of the legislative understanding of identifying patriarchal family structure as exploitation free and argues that the complete ban of commercial surrogacy is not the answer to the exploitation of women who act as surrogates in the current Indian political economy. The author identifies the process of new surrogacy law as a Hindutva morality phase where the inherent violence and exploitation within the patriarchal family system is hidden by the state acting as a benevolent lord.

Published: June 2019

Using data ( N = 1,803) from the Mobile Youth Survey, a community-based study of risk and resilience among predominantly African American youth, this study examines whether indicators of parenting and youth psychological distress mediate the relationship between household member arrest and substance use. Results of structural equation analyses suggest that household member contact with the criminal justice system has indirect effects on adolescent substance use via its impact on parenting. Household member arrest was associated with fewer family rules, monitoring, and curfew restrictions, which in turn was associated with increased frequency of alcohol and marijuana use. Although household member arrest was positively associated with psychological distress, there was no evidence of an internalizing pathway to substance use. Findings underscore the importance of identifying and then intervening on family processes as a way to reduce the impact of family contact with the criminal justice system on young people.

Authors: Orzell Susannah , Joseph Rahul , Ongkasuwan Julina , Bedwell Joshua , Shin Jennifer , Raol Nikhila
Published: June 2019

Objective

The objective of this study was to systematically review the literature regarding vocal fold motion impairment (VFMI), respiratory outcomes, and swallowing outcomes in children following congenital heart surgery (CHS).

Data Sources

PubMed, Embase, Medline, and CINAHL databases.

Review Methods

Data sources were searched from inception to November 30, 2018. Studies that described recovery of VFMI and swallowing function following CHS were included, and a qualitative analysis was performed.

Results

A total of 1371 studies were identified, of which 8 met inclusion criteria for VFMI and 5 met inclusion criteria for swallowing outcomes. Studies including patients who underwent isolate patent ductus arteriosus ligation were excluded. VFMI was present in 8% to 59% of subjects, and rates of recovery ranged from 9% to 96% at 6 months to 6 years of follow‐up. Inability to maintain an oral diet occurred in 14% to 100% of subjects with VFMI and 11% to 61% without VFMI following surgery. Tolerance of an oral diet without tube feeding was present in 66% to 75% of subjects with VFMI and 88% to 100% without VFMI at 24 days to 3.2 years of follow‐up. Limited data suggest that time to extubation is longer in VFMI subjects, but overall hospital length of stay and mortality may not be affected by VFMI status.

Conclusions

Data evaluating dysphagia and VFMI after CHS are limited. Most studies suggest significant improvement in swallowing function, while rate of recovery of VFMI is variable. Future prospective studies with standardized screening and follow‐up are needed to better elucidate outcomes to help develop algorithms for identification and management of VFMI after CHS.

Published: June 2019

Ex vivo organ cultures represent unique research models, as they combine the advantages of cell cultures with those of animal models. Being able to mimic in vivo situations through the use of organ cultures provides an excellent opportunity to investigate cellular processes, molecular pathways and cell–cell interactions, as well as structural and synaptic organisation. Human and animal organ cultures are now well established and comprise sensitive, easy-to-manipulate experimental systems that raise minimal ethical concerns. The eye, in particular, is a very complex organ that is not easy to reproduce in vitro. However, a lot of research has been dedicated to the development of suitable ocular organ cultures. This review covers the various ex vivo retinal organ culture systems available for use in ophthalmology research and compares them with commonly used animal models. In particular, bovine and porcine retinal organ culture systems are described, because the size, anatomy, physiology and vessel morphology of bovine and porcine eyes are similar to the human eye in an undisputed way, thus making them good models. In addition, these animals are widely used by the food industry and the eyes are considered surplus material. A short overview of murine, rat, rabbit, cat, canine and simian retinal organ cultures is also provided.

Published: June 2019

Background

Retention of conception products is a common complication following delivery and remains a diagnostic and management challenge due to non-specific symptoms and ultrasound findings.

Purpose

To introduce a clinical approach for managing patients with suspected retained products of conception following delivery.

Material and Methods

The ultrasound examination included gray-scale and Doppler parameters which classified the patients into three groups: high, moderate, or low probability for retained products of conception. The same classification was used both to stratify individual risk for retained products of conception, as well as for counseling the appropriate management.

Results

The study included 66 patients. Retained products of conception was confirmed in 62%, 32% and 0% of the high, moderate and low probability groups, respectively. Additionally, each group was further divided according to the timing of the ultrasound examination: before or after 42 postpartum days. A significant increase, from 12% to 64%, in the positive predictive value was observed in the moderate probability group when the ultrasound was performed ≥ 42 days postpartum.

Conclusions

In the low probability group, no surgical intervention is recommended. When ultrasound findings are classified as high probability for retained products of conception, surgical evacuation of the uterine content is recommended. For clinically stable women with ultrasound findings consistent with moderate probability, ultrasound follow-up at the end of the puerperal period (42 days) is recommended. This approach may improve the sonographic prediction of retained products of conception and prevent unnecessary interventions.

Published: June 2019

Background

The additive value of dual-energy spectral computerized tomography (DESCT) in breast cancer imaging is still unknown.

Purpose

To investigate the role of DESCT in improving the conspicuity of primary breast cancer.

Material and Methods

Twenty-nine patients who were histopathologically diagnosed with breast cancer and underwent DESCT for staging of lung metastasis were evaluated retrospectively. The visual conspicuity of breast cancer was scored by two readers separately in reconstructed virtual monochromatic images obtained at 40, 60, 80, and 100 keV. A circular region of interest slightly smaller than the maximum contrasted portion of the primary breast cancer was manually placed. Iodine enhancement (HU) and iodine content (mg/mL) values of tumor, normal breast tissue and pectoral muscle, and contrast-to-noise values of images at four different energy levels were calculated.

Results

The lesion conspicuity score peaked at 40-keV series for both readers and was significantly higher than those at other energy levels (all P < 0.001). Lesion iodine enhancement was highest at 40-keV virtual monochromatic image reconstructions ( P < 0.001). The iodine content was significantly higher in tumor than normal breast tissue, and pectoral muscle ( P < 0.001). The highest contrast-to-noise value was obtained at 60 keV (4.0 ± 2.5), followed by 40 keV (3.9 ± 2.2), without a significant difference ( P = 0.33).

Conclusion

The conspicuity of primary breast cancer was significantly higher in low keV virtual monochromatic images obtained by DESCT. This gives us hope that DESCT may play an effective role in detecting incidental breast lesions. It also raises the question of whether quantitative values obtained by DESCT can be used for characterization of primary breast lesion.

Published: June 2019

Objective

A relationship between polymorphisms rs1128503 and rs1045642 in the multidrug resistance 1 gene ( MDR1) and susceptibility to hepatocellular carcinoma (HCC) has been reported but is inconclusive. This study was performed to explore the significance of MDR1 polymorphisms rs1128503 and rs1045642 in screening and diagnosis of HCC.

Methods

Studies of association analyses between MDR1 gene polymorphisms rs1128503 and rs1045642 and HCC were selected from three foreign language databases (PubMed, Cochrane, and Embase) and three Chinese databases (Wanfang, China National Knowledge Infrastructure, and China Knowledge Network) and subjected to meta-analysis.

Results

We found no significant relationship between the rs1128503 polymorphism and susceptibility to HCC in 4 cohorts and no significant relationship between the rs1045642 polymorphism and susceptibility to HCC in 3 cohorts.

Conclusions

There was no relationship between polymorphisms rs1128503 or rs1045642 of the MDR1 gene and susceptibility to HCC.
Appendiceal stump closure with polymeric clips is a reliable alternative to endostaplers
Authors: Vuille-dit-Bille Raphael , Soll Christopher , Mazel Peter , Staerkle Ralph F. , Breitenstein Stefan
Published: June 2019

Objective

Polymeric (Hem-o-lok) clips represent a novel technique with which to ligate the appendiceal stump following laparoscopic appendectomy. We compared the outcomes of using polymeric clips versus endostaplers for complicated and uncomplicated appendicitis.

Methods

Six hundred seventy-three consecutive patients undergoing laparoscopic appendectomy with polymeric clips or endostaplers for acute appendicitis were assessed. The primary outcome was the incidence of intra-abdominal abscesses. Predictors of postoperative intra-abdominal abscesses were calculated using univariate and multivariate analyses.

Results

Polymeric clips were used in 65% of patients and endostaplers were used in 35%. Hem-o-lok clips were not only applied in patients with uncomplicated appendicitis (83%), but also in those with complicated appendicitis (26%). The frequency of intra-abdominal abscesses using polymeric clips and endostaplers was similar in both patients with uncomplicated appendicitis (1% vs. 3%, respectively) and complicated appendicitis (2% vs. 6%, respectively). The univariate and multivariate analyses showed that the stump closure technique was not a risk factor for postoperative abscesses.

Conclusions

Closure of the appendiceal stump using the nonabsorbable Hem-o-lok ligation system in patients with both uncomplicated and complicated appendicitis is a safe alternative to the application of endostaplers.
Sticking to the social mission: Microinsurance in bottom of the pyramid markets
Authors: Elango B , Chen Stephen , Jones Jim
Published: June 2019

The purpose of this article is to understand what drives social enterprises in bottom of the pyramid (BOP) markets to stick to or drift away from their social mission. Based on an analysis of 192 microinsurance operators in 26 emerging markets, we find that (1) when donors are involved in the operations of the social enterprise, this leads to a greater commitment to the social mission and (2) social enterprises located in countries with poorly performing governments tend to have a lower commitment to their social mission. Given the need for social services in such countries, we offer some suggestions to increase the chances of social enterprises staying committed to their social mission.
