Published: June 2020

As location-based services using mobile devices have become globally popular these days, social network analysis (especially, community detection) increasingly benefits from combining social relationships with geographic preferences. In this regard, this article addresses the emerging problem of geosocial community detection. We first formalize the problem of
geosocial co-clustering
, which co-clusters the users in social networks and the locations they visited. Geosocial co-clustering detects higher-quality communities than existing approaches by improving the
mapping clusterability
, whereby users in the same community tend to visit locations in the same region. While geosocial co-clustering is soundly formalized as
non-negative matrix tri-factorization
, conventional matrix tri-factorization algorithms suffer from a significant computational overhead when handling large-scale datasets. Thus, we also develop an efficient framework for geosocial co-clustering, called
GEOsocial COarsening and DEcomposition (GEOCODE)
. To achieve efficient matrix tri-factorization, GEOCODE reduces the numbers of users and locations through coarsening and then decomposes the single whole matrix tri-factorization into a set of multiple smaller sub-matrix tri-factorizations. Thorough experiments conducted using real-world geosocial networks show that GEOCODE reduces the elapsed time by 19–69 times while achieving the accuracy of up to 94.8% compared with the state-of-the-art co-clustering algorithm. Furthermore, the benefit of the mapping clusterability is clearly demonstrated through a local expert recommendation application.

Published: June 2020

Vehicular trafﬁc in metropolitan areas turns congested along either paths or periods. As a case study, we have considered a mass transport system with a bus ﬂeet that rides over exclusive lanes across streets and avenues in an urban area that does not allow
the circulation of lightweight vehicles, cargo, and motorcycles. This trafﬁc ﬂow becomes congested due to the absence of restriction policies based on criteria. Moreover, the exclusive lanes are at ground level, decreasing lanes for other vehicles. The main objective of this proposal consists of controlling the access to the exclusive lanes by a cyber-physical system following authorization conditions, verifying the permission status of a vehicle by the accurate recognition of license plates to reduce trafﬁc congestion. Therefore, in the case of invading an exclusive lane without permission, the vehicle owner gets a notiﬁcation of the ﬁne with the respective evidence.
A simplified machine learning approach for recognizing human activity
Authors: Lateef Haroon P.S Abdul , Eranna U. 
Published: June 2020

With the wide ranges of real-time event feed capturing devices, there has been significant progress in the area of digital image processing towards activity detection and recognition. Irrespective of the presence of various such devices, they are not adequate to meet dynamic monitoring demands of the visual surveillance system, and their features are highly limited towards complex human activity recognition system. Review of existing system confirms that still there is a large scope of enhancement as they lack applicability to real-life events and also doesn't offer optimal system performance. Therefore, the proposed manuscript presents a model for activity recognition system where the accuracy of recognition operation and system performance are retained with good balance. The study presents a simplified feature extraction process from spatial and temporal traits of the event feeds that is further subjected to the machine learning mechanism for boosting recognition performance
Sexual dimorphism in Scutiger boulengeri, an endemic toad from the Tibetan Plateau

Abstract
The evolution of sexual dimorphism has long fascinated evolutionary biologists and theory suggests that variation in sexual dimorphism is a consequence of selective forces acting differently on morphological traits in males versus females. Here, we analyzed sexual differences in size and shape of the Boulenger’s lazy toad, Scutiger boulengeri, based on the intersex variation pattern of sixteen morphometric traits including body size. The results suggested that sexual dimorphism was apparent in body size and some body shapes (e.g., head length and width, internasal space, interorbital space, diameter of lower arm and tibia width) of this toad. The bigger body size in females may be relevant to fecundity selection, a larger head in males as well as a broader internasal and interorbital space may be subject to male-male competition in combination with ecological selection, and both robust forelimbs and hindlimbs in males may be related to mating and competitive behaviors. These results are discussed with respect to the above selection procedures and possible sex differences in life history traits.

Abstract
The endemic terrestrial Crown Snail from Southern Thailand formerly in Macrochlamys Gray, 1847 is now described as Taphrenalla Pholyotha & Panha gen. nov., based on comparative morphology and molecular data. Overall, eleven Taphrenalla species are now recognized, including two nominal species: T. asamurai and T. diadema. A total of nine new species are proposed: T. alba sp. nov., T. conformis sp. nov., T. corona sp. nov., T. dalli sp. nov., T. incilis sp. nov., T. macrosulcata sp. nov., T. parversa sp. nov., T. pygmaea sp. nov. and T. zemia sp. nov. The molecular phylogeny constructed from the mitochondrial cytochrome oxidase c subunit I (COI) and 16S rRNA gene fragments plus the nuclear 28S rDNA gene fragments revealed that Taphrenalla gen. nov. is monophyletic with a well-supported clade. The diagnostic characters of Taphrenalla gen. nov. are the shell sculpture with several radial grooves, body with well-developed colourful stripes running from the head to tail, and genitalia similar to Macrochamys but with an un-coiling epiphallic caecum. The spermatophore has one or two spines near the sperm sac and a spineless tail.
Burdens of Proof
Authors: Protschky Susie 
Published: June 2020

Abstract
There is but a limited scholarship on photographic sources from the Dutch military actions during the Revolusi Nasional Indonesia (Indonesian National Revolution) (1945–1949), and what exists almost entirely neglects perhaps the largest component of the archives: Dutch soldiers’ amateur photographs. Yet this category of photographs has simultaneously attracted much public and media controversy. This article contends that a narrow range of soldiers’ amateur photographs have thus far borne an anomalously weighty burden of proof to substantiate the nature and limits of extreme violence during the National Revolution, one that is brittle and difficult to sustain unless historians begin to broaden the focus of investigations into photographic archives. This article also investigates what it may mean for present-day Indonesians to see their ancestors as perpetrators as well as victims of violence and, importantly, as occupants of the ambiguous categories between both ends of this spectrum. What are the ethics of looking at and reproducing these photographs, and to whom do they belong?
Report on the Göttingen Septuagint
Authors: Albrecht Felix 
Published: June 2020

Abstract
This article provides a brief history of the Göttingen Septuagint Editions up to 2019, and focuses on the new Psalter Project “Editio critica maior des griechischen Psalters” (Akademie der Wissenschaften zu Göttingen), which started at the beginning of 2020. The article illustrates some of the challenges of the planned editorial work, and uses Psalm 1 as a test case. First, an overview is provided of the editorial history, from the earliest printed versions that reveal a major influence of the Lucianic recension, to the Sixtine edition that marks a turning point, followed by all other modern editions (e.g. by Paul Anton de Lagarde and Alfred Rahlfs). Second, attention is drawn to one of the most urgent research tasks, namely the reconstruction of the fragmentary hexaplaric tradition, giving examples of the hexaplaric fragments of Psalm 1 transmitted in ms. Rahlfs 113 (Cod. Ambros. B 106 sup.) and Rahlfs 271 (Cod. Vat. gr. 1747).

Published: June 2020

Objective: Rates of suicidality are higher in military than comparable civilian populations. The period of transition from regular military service may be a time of particular vulnerability. In order to best inform early intervention and prevention strategies, we sought to investigate the childhood determinants (trauma and disorder) of self-reported past-year suicidality (thoughts, plans or attempts) in a population of Australian Defence Force men who had recently (in the previous 5 years) transitioned from regular military service. Methods: We analysed self-report, and detailed interview, cross-sectional data to investigate the association between retrospectively reported past-year suicidality and childhood factors (disorder and trauma) and whether these relationships were independent of each other and adult-onset trauma and disorder. We utilised logistic regression techniques and generalised structural equation modelling. Results: The prevalence of suicidality in transitioned men was 21.6% (95% confidence interval [CI]: [19.9, 23.3]). Suicidality was associated with childhood-onset interpersonal trauma and anxiety and adult-onset anxiety and depression. Generalised structural equation modelling demonstrated that the pathway between childhood interpersonal trauma and suicidality was not fully mediated by childhood anxiety. Restricting the analyses to those previously deployed demonstrated that suicidality had a direct and significant association with childhood-onset factors (anxiety and interpersonal trauma) and adult-onset trauma (deployment and non-deployment related). Conclusion: This study sheds light onto the significance of childhood factors (interpersonal trauma and anxiety) in a population undergoing transition that may revive pre-existing vulnerabilities. These findings have the potential to aid early intervention and prevention strategies in identifying those at risk prior to transition. These findings also imply that early interventions targeting anxiety and interventions to reduce social instability during the transition period may be useful in reducing suicidality during this time. Further prospective studies are needed to further explore these novel findings.
The Binary-Based Model (BBM) for Improved Human Factors Method Selection

Published: June 2020

Objective This paper presents the Binary-Based Model (BBM), a new approach to Human Factors (HF) method selection. The BBM helps practitioners select the most appropriate HF methodology in relation to the complexity within the target system. Background There are over 200 HF methods available to the practitioner and little guidance to help choose between them. Method The BBM defines a HF “problem space” comprising three complexity attributes. HF problems can be rated against these attributes and located in the “problem space.” In addition, a similar HF “approach space” in which 66 predictive methods are rated according to their ability to confront those attributes is defined. These spaces are combined into a “utility space” in which problems and methods coexist. In the utility space, the match between HF problems and methods can be formally assessed. Results The method space is split into octants to establish broad groupings of methods distributed throughout the space. About 77% of the methods reside in Octant 1 which corresponds to problems with low levels of complexity. This demonstrates that most HF methods are suited to problems in low-complexity systems. Conclusion The location of 77% of the rated methods in Octant 1 indicates that HF practitioners are underserved with methods for analysis of HF problems exhibiting high complexity. Application The BBM can be used by multidisciplinary teams to select the most appropriate HF methodology for the problem under analysis. All the materials and analysis are placed in the public domain for modification and consensus building by the wider HF community.
Reconciling the State and Diffused Autonomy? Political Brokers in Venezuelan Poder popular
Authors: Boni Stefano 
Published: June 2020

The most widespread implementation of the autonomous sovereignty of the popular sectors in the socialist policies of Chávez’s Venezuela, known as poder popular (popular power), is the consejo comunal (communal council), a neighborhood assembly that has received sizable state funding to implement self-managed projects ranging from house renovation to local public works and from social events to small-scale productive activities. Examination of the establishment and operation of these councils in Cumaná (Estado Sucre)—their successes and failures, popular involvement and personal corruption—reveals the ambiguous role within them of political brokers employed by local administrations and heading the party’s smallest organizational units and shows how incorporation of forms of direct democracy into larger institutions (the government and the party) hinders the exercise of autonomy. La implementación más extensa de la soberanía autónoma de los sectores populares en las políticas socialistas de la Venezuela de Chávez, mejor conocida como poder popular, yace en el consejo comunal, un tipo de asamblea vecinal que ha recibido considerables fondos estatales para implementar proyectos autogestionados: desde la renovación de casas hasta obras públicas locales, desde eventos sociales hasta actividades productivas a pequeña escala. Un análisis en torno al establecimiento y funcionamiento de estos consejos en Cumaná, Estado Sucre (sus éxitos y fracasos, participación popular y problemas de corrupción personal) revela el ambiguo rol que dentro de ellos jugaban los agentes políticos empleados por las administraciones locales para encabezar las unidades organizativas más pequeñas del partido. También muestra cómo la incorporación de formas de democracia directa a instituciones más grandes (el gobierno y el partido) obstaculizan el ejercicio de la autonomía.
Training Normal Hearing to Greater Usefulness: A Progress Report
Authors: Norton Fay-Tyler M. 
Published: June 2020

There is current widespread interest in the use of hearing by blind individuals for the purpose of better orientation and better mobility. The Office of Vocational Rehabilitation is now supporting at least three hearing projects of major proportions. The most recent grant was made to C. W. Shilling Auditory Research Center, in Groton, Connecticut. They are equipped with the most modern instrumentation and, according to John Dupress, of the American Foundation for the Blind, they intend to do research which will lead to the identification of auditory cues used by skilled blind travelers. They also intend to design training material for the rehabilitation of blind persons who are not able to travel independently with a cane or a dog. Matching funds for this project have been provided by Seeing Eye, Inc., Morristown, New Jersey. A second project has been in progress about two years at the Industrial Home for the Blind, in Brooklyn, New York. Their objective is service to blind individuals who are hard of hearing. An excellent description of this project, written by Dr. Moe Bergman, the principal investigator, appeared in the December 1959 issue of the New Outlook.1 In the same issue of the New Outlook there appeared also an introduction to the hearing research project in progress at the Cleveland Society for the Blind.3 Our purpose is to develop methods for training normal hearing of blinded persons to greater usefulness. The following article describes the research further and presents some findings.—F.M.N.

Background: Evidence suggests that the AKT1 gene may modulate the degree to which cannabis use induces cognitive alterations in patients with a psychotic disorder. Aim: To examine the interplay between AKT1 and cannabis use in terms of the cognitive performance of the general population. Methods: Our sample consisted of 389 Spanish university students. Sustained attention was measured via the Continuous Performance Test–Identical Pairs, immediate and delayed verbal memory with the Logical Memory subtest of the Wechsler Memory Scale, and working memory with the Wisconsin Card Sorting Test. Lifetime cannabis use frequency was assessed and individuals were classified as cannabis users or non-users. Two single nucleotide polymorphisms of the AKT1 gene were genotyped and, according to previous studies, each subject was defined as a carrier of two, one or no copies of the haplotype (rs2494732(C)–rs1130233(A)). Multiple linear regressions were conducted to test the effect of the genetic variability and cannabis use (and their interaction) on cognitive performance. Results: An effect of the AKT1 haplotype was found on attention scores: individuals with two copies of the haplotype performed better (β=0.18, p<0.001 (adjusted for false discovery rate)), while neither cannabis nor the AKT1–cannabis interaction was associated with attention. No effect of AKT1, cannabis or the AKT1–cannabis interaction was found on verbal memory or working memory. Conclusions: Our study provides additional evidence that AKT1 modulates cognitive performance. However, in our non-clinical sample, the previously reported interaction between cannabis use and the AKT1 gene was not replicated.

Background Computed tomography perfusion (CTP) can provide information on blood perfusion as a reliable marker of tumor response to therapy. Purpose To assess the role of volume CTP (vCTP) parameters in predicting treatment response to concurrent chemoradiotherapy (CCRT) for cervical cancer. Material and Methods Thirty-three patients with cervical cancer underwent vCTP. Three CTP parameters of cervical cancer—including arterial flow (AF), blood volume (BV), and permeability surface (PS)—were measured in two different ways: the region of interest incorporating the “local hot” with the highest enhancement and “cold spot” with the lowest enhancement; and “whole-tumor” measurements. The patients were divided into non-residual and residual tumor groups according to the short-term response to treatment. The clinical and perfusion parameters were compared between the two groups. Results There was no significant difference in age, body mass index, FIGO stage, pathological grade, or pretreatment tumor size between the two groups ( P > 0.05). The non-residual tumor group had higher pretreatment AF in high-perfusion and low-perfusion subregions than the residual tumor group ( P <0.05), but the AF in whole-tumor regions was not different between the two groups ( P > 0.05). There were no differences in BV and PS between the two groups ( P > 0.05). The diagnostic potency of AF in the low-perfusion subregion was higher than that in the high-perfusion subregion. Conclusion vCTP parameters are valuable for the prediction of short-term effects. The AF in the low-perfusion subregion was a more effective index for predicting treatment response to CCRT of cervical cancer.
Feasibility, Utility, and Limitations of a Rapid Community Behavioral Diagnosis for Social Distancing During the 2020 Coronavirus Pandemic

Published: June 2020

Purpose: To evaluate the feasibility, utility, and limitations of a rapid community behavioral diagnosis (RCBD) for social distancing behaviors to prevent coronavirus transmission during a global coronavirus pandemic. Design: Using social media for recruitment, we partnered with a local community task force to administer a brief online survey. Setting: Residential urban community. Sample: Eighty-four community members, the majority of whom were white, female, college educated completed the survey. Measures: Theory of planned behavior constructs: behavioral intentions, attitudes, perceived norms, and perceived behavioral control for 3 social distancing behaviors: maintaining a 6-foot distance, avoiding places people congregate, and staying home as much as possible. Analysis: Path analyses were conducted to understand significant determinants of intentions for each behavior to guide the development of locally tailored health promotion messages. Results: The RCBD was implemented, and results were communicated to the community within 1 week. Intentions were high across the 3 behaviors but lowest for staying home as much as possible. Younger participants had lower intentions of maintaining a 6-foot distance than older participants. For each behavior, specific recommendations for health promotion messaging emerged based on how attitudes, norms, and perceived behavioral control related to intentions. Conclusion: In a situation where local community action is paramount for reducing coronavirus transmission, this RCBD process is feasible and useful for informing local health promotion.

Objective: To determine the mediating role of gratitude in the relationship between attachment styles and psychological well-being in students. Method: We selected 200 students using randomised cluster sampling in the academic year 2016–2017. They completed the attachment style, psychological well-being and gratitude questionnaires. Results: On path analysis, secure attachment style had a positive relationship with both gratitude and psychological well-being. Conversely, anxiety-avoidance styles had a negative relationship with both outcomes. Conclusions: Gratitude plays a mediating role attachment and psychological well-being. These results may have implications for the development of interventions to improve mental well-being with a focus on enhancing gratitude.
