A qualitative study of the practices and experiences of staff in multidisciplinary child sexual exploitation partnerships in three English coastal towns

This article presents findings from a qualitative study of the practices and experiences of people working in multi-disciplinary child sexual exploitation (CSE) partnerships in three coastal towns in England. The study is based on focus groups conducted with 36 practitioners from a range of professional groups, including police, social work, substance misuse, education, specialist youth workers, sexual health, and statutory and non-statutory children's services. The article begins with an overview of the three towns and the structure of their responses to CSE. It goes on to explore a range of factors, which contribute to the local issues around CSE and which affect and direct multiagency working. These include practitioner perspectives on CSE vulnerabil-ity, the discrepancy between young peoples' and practi-tioners' views about “exploitation”, a discussion of how CSE perpetrators initiate and develop contact with young people and the role of incentives—including drugs and alcohol—as part of CSE exploitation. We finish by drawing out some general conclusions.
Self‐Consistent Ice Mass Balance and Regional Sea Level From Time‐Variable Gravity

Measurements of time‐variable gravity from the Gravity Recovery and Climate Experiment (GRACE) and the GRACE Follow‐on (GRACE‐FO) missions are an invaluable tool for monitoring changes in the mass of the Earth's glaciated regions. We improve upon estimates of glacier and ice sheet mass balance from time‐variable gravity by including instantaneous spatiotemporal variations in sea level. Here, a least squares mascon technique is combined with solutions to the sea level equation to iteratively correct the GRACE/GRACE‐FO data for the induced sea level response on a monthly basis. We find that variations in regional sea level affect ice sheet mass balance estimates in Greenland by approximately 4% and in Antarctic by approximately 5%. Since 2002, the Greenland ice sheet has been losing mass at an average rate of 263 ± 23 Gt/yr, and the Antarctic ice sheet has been losing mass at average rates between 90 ± 52 and 122 ± 53 Gt/yr depending on the rate of glacial isostatic adjustment. The mass losses from both ice sheets represent an increase of 15.6 ± 2.0 mm to global mean sea levels since 2002.
Eigenspace Solution for AOA Localization in Modified Polar Representation

This paper focuses on the development and analysis of algebraic solution for source localization using angles of arrival (AOAs) in the modified polar representation (MPR), where sensor position errors are present. MPR uses the arrival angle(s) and inverse-range to represent the source location, thereby integrating the localization of the source to a single framework regardless it is in the near-field or far-field. Previous solution for AOA localization in MPR ignores sensor position errors and uses the iterative Maximum Likelihood method with a coarse semi-definite relaxation solution as the initialization, which is computationally demanding and does not ensure global convergence. We propose the constrained eigenspace technique to this localization problem that yields computationally attractive algebraic solution without having the local convergence issue. Depending on the constraints imposed, two solutions are developed. One is more computationally efficient and the other has smaller bias. The solutions are studied theoretically by mean-square analysis to characterize their statistical performance. Simulations validate the CRLB performance of the two proposed solutions under Gaussian noise.
A Fast Analysis Method of Mechanical Characteristics for Railway Vehicle Traction Motor Hanging Leaf Spring Based on Analytical Calculation

In order to analyse the mechanical characteristics of the traction motor hanging leaf spring of railway vehicles quickly and effectively, by establishing the vertical and the lateral force model of the hanging leaf spring, the mathematical model for analysing the stiffness characteristics and the stress characteristics of the hanging leaf spring were established based on analytical calculation, and the reliability of the mathematical model was verified by the loading-unloading test. The test results show that the analysis method for analysing the mechanical characteristics of the traction motor hanging leaf spring established is reliable. This research can provide a certain popularization and application value for the analysis and design of the railway vehicle traction motor hanging leaf spring.
Introducing switched adaptive control for quadrotors for vertical operations

With the advent of intelligent transport, quadrotors are becoming an attractive solution while lifting or dropping of payloads during emergency evacuations, construction works, etc. During such operations, dynamic variations in (possibly unknown) payload cause considerable changes in the system dynamics. However, a systematic control solution to tackle such interchanging dynamical behavior is still missing. This paper proposes a switched dynamical framework to capture the interchanging dynamics of a quadrotor during vertical operations and a robust adaptive control solution to tackle such dynamics when it is unknown. The stability of the closed‐loop system is studied analytically and the effectiveness of the proposed solution is verified via simulations.

1. Assistant Professor, HOD, Lahore Business School, University of Lahore Sargodha campus, Pakistan 2. Assistant Professor, Department of Business Administration, University of Sahiwal, Pakistan PAPER INFO ABSTRACT Received: January 11, 2020 Accepted: March 18, 2020 Online: March 31, 2020 The purpose of this study is to investigate the relationship between Psychological Contract Breach (PCB) and employee's responses through the mediating mechanism of leader-member exchange (LMX). Globally, workplace leadership, employers, and employee’s relationship are crucial phenomena to explore. This study explores the impact of the psychological contract breach on employees' active and passive responses through the mediating role of leader-member exchange. Moreover, present study tested these tri-phenomena via a self-administered questionnaire of 250 employees from different organizations. In this regard, present study applied structure equation modeling to evaluate the defined relationship. Furthermore, an employee with high leader-member exchange was less likely to respond to psychological contract breach with exit and voice than the employees with the low leader-member exchange. This study recommends to policy makers, owners and decision makers that leader could play an important role during breach of psychological contract
Effects of exposure time and ratio of irradiated larvae from three medfly strains on progeny yield in Diachasmimorpha longicaudata (Hymenoptera: Braconidae) mass rearing

ABSTRACT An augmentative biological control strategy against Ceratitis capitata (= medfly) in fruit-producing irrigated-valleys of San Juan, central-western Argentina, has been recently implemented by the San Juan Fruit Fly Control and Eradication Program. The Asian-native parasitoid Diachasmimorpha longicaudata is currently reared at the San Juan Medfly and Parasitoids Mass Rearing Facility for this purpose. In this regard, the objective of this study was to evaluate adult emergence and offspring sex ratio to improve parasitoid production. Three medfly strains at different host larvae densities and exposure times to female parasitoids were assessed. Prevalence of superparasitism was also considered. Three parasitoid population lines were used in the trials: one reared on medfly larvae of the Vienna-8 temperature-sensitive lethal (tsl) genetic sexing strain without inversion, and the other two on larvae of biparental medfly strains native to San Juan (central-western Argentina) and Tucumán (northwestern Argentina). Gamma-irradiated 6 d-old larvae (early third-instars) of each medfly strain were exposed to parasitoids for 30, 60, 90, and 120 min at 3:1, 6:1, and 9:1 host/parasitoid ratios. The Vienna-8 C. capitata strain was as efficient in producing parasitoids as both biparental native strains. Medfly larvae exposed to 10 female parasitoids for a relatively long time (1.30 hrs) at a high ratio (6–9:1) of host to parasitoid were enough to achieve the highest mean adult emergence (50–60%) and a female-biased offspring sex ratio. Superparasitism positively influenced female parasitoid production. These findings may be used to develop a more cost-effective mass rearing method for D. longicaudata.
Morphometrical study on pre-antral ovarian follicles of buffalo during different seasons.

The present study was conducted on left and right ovaries of 100 adult buffaloes during different seasons. The whole ovary was cut serially at a thickness of 10 µ. Every 20 th section was stained with haematoxylin and eosin stain and the number of pre-antral (primordial and primary) follicles in an ovary was counted. The primordial follicles had flattened pre-granulosa cells that became cuboidal and divided during follicular activation which was an index of activation. The average number of primordial and primary follicles was significantly (p < 0.05) higher during winter and autumn as compared to other seasons. The number of follicles was more in right ovary as compared to left, though the difference was insignificant.
KRAS mutations testing in non-small cell lung cancer: the role of Liquid biopsy in the basal setting

In advanced stage non-small cell lung cancer (NSCLC) patients, Kirsten Rat Sarcoma Viral Oncogene Homolog (KRAS) testing may soon acquire a predictive significance to select patients for AMG510 treatment. Since tissue samples are not always available, liquid biopsy may represent a viable option for KRAS testing. Here, we review the last three years clinical practice performed on 194 plasma based liquid biopsies by next generation sequencing (NGS) SiRe® panel. In particular, 36 (18.6%) KRAS mutated cases were identified, with an overall median allelic frequency of 5.0% (ranging between 0.2% and 46.8%). No concomitant mutations were observed in the other NSCLC clinical relevant genes included in the SiRe® panel, such as epidermal growth factor receptor (EGFR) and v-Raf murine sarcoma viral oncogene homolog B (BRAF). Exon 2 p.G12C was the most common detected mutation (13/36, 36.1%). In conclusion, our data update and confirm that SiRe® NGS panel represents a robust analytical tool to assess KRAS mutational status on circulating tumor DNA. Further investigation is required to design more cost-effective diagnostic algorithms to harmonize clinical relevant biomarker testing on tissue and blood in advanced stage NSCLC clinical practice.
Micro Sand Engine Beach Stabilization Strategy at Puerto Morelos, Mexico

In the last decade, innovative beach nourishment strategies have been developed, driven by the increased worldwide interest in environmentally friendly coastal protection measures. In this context, the massive nourishment project of the Netherlands, known as Sand Engine, begun in 2011, has been hailed as a successful means of beach protection. Continuous monitoring, field campaigns, and numerical modeling have shown that the great volume of sand deployed is gradually transported by the waves and currents along the coastline, avoiding the need for repeated invasive, small scale beach replenishments. A very small, bell-shaped Sand Engine was designed to protect the beachfront at a tourist resort near Puerto Morelos, Mexico. To estimate the morphological response of the beach and the functioning of the micro Sand Engine as a sand reservoir, XBeach numerical modelling was applied to the project. The micro Sand Engine is seen to be a sustainable and eco-friendly coastal protection measure, especially applicable when a large nourishment project is not viable. Maintenance work for the nourishment is cost and time effective, and any negative impacts to sensitive ecosystems nearby can be detected and controlled quickly.
Impact of Tensor Cores and Mixed Precision on the Reliability of Matrix Multiplication in GPUs

Matrix multiplication (MxM) is a cornerstone application for both high-performance computing and safety-critical applications. Most of the operations in convolutional neural networks for object detection, in fact, are MxM related. Chip designers are proposing novel solutions to improve the efficiency of the execution of MxM. In this article, we investigate the impact of two novel architectures for MxM (i.e., tensor cores and mixed precision) on the graphics processing units (GPUs) reliability. In addition, we evaluate how effective the embedded error-correcting code is in reducing the MxM error rate. Our results show that low-precision operations are more reliable, and the tensor core increases the amount of data correctly produced by the GPU. However, reducing precision and the use of tensor core significantly increase the impact of faults in the output correctness.
Design of High Frequency Single and Double Gate Laterally-Contacted InGaAs/InAlAs HEMTs

Background and Objectives: High electron mobility transistors (HEMTs) are designed so that they are able to work at higher frequencies than conventional transistors and this has made them an attractive topic of research. Methods: Two developed designs of InGaAs/InAlAs high electron mobility transistors have been studied. The proposed laterally contacted HEMTs satisfy the desired high frequency characteristics and are good candidates for high frequency applications. Two kinds of HEMTs have been designed and simulated: single-gate laterally contacted HEMT (SGLC-HEMT) and doublegate laterally contacted HEMT (DGLC-HEMT). Results: The proposed SGLC-HEMT exhibits 111 GHz current-gain cut-off frequency. By using double-gate design, the current-gain cut-off frequency has been increased to 256 GHz. The simulation results show that the maximum oscillation frequency for the proposed SGLC and DGLC HEMTs, are 410 GHz and 768 GHz, respectively. The maximum value of transconductance (gm) for SGLC-HEMT is obtained 620 mS/mm while it is 1130 mS/mm for DGLC-HEMT. Conclusion: In order to increase the fT and fmax, instead of decreasing the gate length which is a restricted solution because of short channel effects, a very efficient structure was proposed. The designed HEMT benefits from laterally source and drain contacts. The results showed superior performance of the laterally contacted HEMTs compared to top contacted ones. The best frequency response was obtained for DGLC-HEMT. The proposed DG-HEMT design could improve the current-gain cut-off frequency and maximum oscillation frequency to 256 GHz and 768 GHz, respectively. The comparison of the performance of the DGLC-HEMT with SGLC-HEMT and with previously reported double gate HEMTs, verified the significant improvements in DC and AC characteristics of the HEMTs caused by the proposed design.
Effects of Land Use Types on Selected Soil Properties in Central Highlands of Ethiopia

Rapid land use changes have been observed in recent years in central Ethiopia. The shift from natural ecosystem to artificial ecosystem is the main direction of change. Therefore, this study was initiated to assess the effects of land use types on selected soil properties in Meja watershed, central highlands of Ethiopia. The randomized complete block design, including three adjacent land use types as treatments with three replications and two soil depths (0–15 and 15–30 cm), was applied in this study. There were significant differences in some soil properties among the three land use types. Lower soil pH and electric conductivity were observed in cultivated land soils than Eucalyptus woodlots soils. This has indicated the worsening soil conditions due to the shift from Eucalyptus woodlots to cultivated land. Less decomposition rate of the Eucalyptus leaves and debris collection for fuel could result in lowest soil organic carbon at the upper layer of Eucalyptus woodlot soils. However, the highest soil organic carbon at the lower layer was observed in Eucalyptus woodlot soils. The presence of highest soil potassium, cation exchange capacity, and exchangeable potassium in cultivated land soil was related to application of artificial fertilizers. Grassland soils have highest exchangeable sodium at the lower layer while highest soil carbon and sum cations at the upper layer, which can be related to the grass root biomass return and less surface runoff on grassland. There was the highest exchangeable sodium percentage on Eucalyptus woodlot soils at the upper layer; it can be due to the less surface nutrient movement and growth characteristics of the tree. The soils in cultivated land was shifted to more acidic and less electric conductivity.This shift can lead to soil quality deterioration that affects the productivity of the soils in the future.Nutrient leaching, application of artificial fertilizer, soil erosion, and continuous farming have affected the soil properties in cultivated land. The presence of highest exchangeable sodium percentage and lowest sum of cations at the upper layer of soil in Eucalyptus woodlot should be noted for management and decision makers. The previous negative speculations on Eucalyptus woodlots which can be related with the soil texture, soil moisture, bulk density, total nitrogen, exchangeable magnesium, calcium, and available sulfur should be avoided because there were no significant differences observed among the three land use types in the study area. The study recommends further studies on the effects of Eucalyptus on soil properties by comparing among different ages and species of Eucalyptus. Finally, planting of Eucalyptus on central highlands of Ethiopia should be supported by land use management decision.
An evaluation of the distribution pattern of the common chaffinch (Fringilla coelebs) in Turkey

The common chaffinch (Fringilla coelebs) is one of the most common and widespread of the Western Palearctic songbirds and breeds primarily in natural forests in the northern, western, and southwestern parts of Turkey. We reevaluated the distribution of this species in Turkey with recent observational data. Although this species has been considered a breeder in southeastern Turkey, results of this study suggest that it probably does not breed in the region any longer. We examined the effect of climatic (temperature, precipitation, potential evapotranspiration) and topographic (altitude) variables on common chaffinch distribution in Turkey. Our findings show that the presence of this species is more likely in zones with high summer precipitation, which is probably associated with primary productivity and the habitats favored by this species.
Mapping quantitative trait loci (QTL) for resistance to Phytophthora palmivora in T. cacao

La pourriture brune des cabosses, due a Ph ' vtophthora palmivora, est largement repandue de par le monde et pourrait etre responsable de pertes importantes sur les recoltes. Dans le cadre d'un projet international, l'etude de la base genetique de la resistance a P. pahwivora a ete initie, en utilisant comme strategie le tracage de carte. Une population de 140 individus situee a Bingerville (Cote d'Ivoire) fut analysee. Elle provenait d'un croisement entre deux geniteurs heterozygotes: UPA 402, un Forestero haut-amazonien, et UF676, un Trinitario. Une carte des linkages genetiques satures fut etablie a l'aide de marqueurs isozymes et moleculaires (RAPD, RFLP, AFLP, microsatellites). Les caracteres de resistance furent evaluees par des tests sur feuilles et par analyse des pertes dans les recoltes pendant plusieurs annees. Plusieurs LCQ furent observes dans le genome. Les marqueurs moleculaires presentant des liaisons pourraient etre utilises dans le cadre d'une "selection assistee par marqueur". (Resume d'auteur)
Stereoscopic reconfiguration for 3D displays

In this paper, we present a method to reconfigure 3D movies in order to minimize distortion when seen on a different display than the one it has been configured for. By their very nature, 3D broadcasts come with a stereoscopic pair to be seen by the left and right eyes. However, according to reasons that we ought to explain in the paper, the cameras used to shoot a movie are calibrated according to specific viewing parameters such as the screen size, the viewing distance and the eye separation. As a consequence, a 3D broadcast seen on a different display (say a home theater or a PC screen) than the one it has been configured for (say an IMAX R screen) will suffer from noticeable distortions. In this paper, we describe the relationship between the size of the 3D display, the position of the observer, and the intrinsic and extrinsic parameters of the cameras. With this information, we propose a method to reorganize the stereoscopic pair in order to minimize distortion when seen on an arbitrary display. In addition to the raw video pair, our method uses the viewing distance, a rough estimate of the 3D scene, and some basic information on the 3D display. An inpainting technique is used to fill disoccluded areas.
The Effect of Mobile Device Use and Headline Focus on Investor Judgments

This study conducts two experiments to examine how investors’ judgments differ when they read a press release using either a mobile device or a computer. Results show that when investors use a mobile device, information related to a specific headline (mentioning a specific part of the news like “net income” or “revenue”) influences their investment judgments more than when investors use a computer. This effect is robust to specific headlines that focus on either positive or negative information. In contrast, investors’ judgments do not differ when they use a mobile device compared to a computer and the headline is general (using the broad term “results”). We replicate our findings in a second experiment and provide evidence that the observed effect occurs because investors who use their mobile device are in a more distracted frame of mind, which in turn increases the influence of prominent information. Our results suggest that managers’ presentation choices may have a greater influence on investors as they increasingly rely on mobile devices to research and execute investment decisions.
