Authors: Zhang Jicun , Song Xueping , Feng Jiawei , Fei Jiyou
Published: September 2021

It is an important part of security inspection to carry out security and safety screening with X-ray scanners. Computer vision plays an important role in detection, recognition, and location analysis in intelligent manufacturing. The object detection algorithm is an important part of the intelligent X-ray machine. Existing threat object detection algorithms in X-ray images have low detection precision and are prone to missed and false detection. In order to increase the precision, a new improved Mask R-CNN algorithm is proposed in this paper. In the feature extraction network, an enhancement path is added to fuse the features of the lower layer into the higher layer, which reduces the loss of feature information. By adding an edge detection module, the training effect of the sample model can be improved without accurate labeling. The distance, overlap rate, and scale difference between objects and region proposals are solved using DIoU to improve the stability of the region proposal’s regression, thus improving the accuracy of object detection; SoftNMS algorithm is used to overcome the problem of missed detection when the objects to be detected overlap each other. The experimental results indicate that the mean Average Precision (mAP) of the improved algorithm is 9.32% higher than that of the Mask R-CNN algorithm, especially for knife and portable batteries, which are small in size, simple in shape, and easy to be mistakenly detected, and the Average Precision (AP) is increased by 13.41% and 15.92%, respectively. The results of the study have important implications for the practical application of threat object detection in X-ray images.

Published: September 2021

Objective. To explore the therapeutic targets, network modules, and coexpressed genes of Radix Rhei Et Rhizome intervention in cerebral infarction (CI), and to predict significant biological processes and pathways through network pharmacology. To explore the differential proteins of Radix Rhei Et Rhizome intervention in CI, conduct bioinformatics verification, and initially explain the possible therapeutic mechanism of Radix Rhei Et Rhizome intervention in CI through proteomics. Methods. The TCM database was used to predict the potential compounds of Radix Rhei Et Rhizome, and the PharmMapper was used to predict its potential targets. GeneCards and OMIM were used to search for CI-related genes. Cytoscape was used to construct a protein-protein interaction (PPI) network and to screen out core genes and detection network modules. Then, DAVID and Metascape were used for enrichment analysis. After that, in-depth analysis of the proteomics data was carried out to further explore the mechanism of Radix Rhei Et Rhizome intervention in CI. Results. (1) A total of 14 Radix Rhei Et Rhizome potential components and 425 potential targets were obtained. The core components include sennoside A, palmidin A, emodin, toralactone, and so on. The potential targets were combined with 297 CI genes to construct a PPI network. The targets shared by Radix Rhei Et Rhizome and CI include ALB, AKT1, MMP9, IGF1, CASP3, etc. The biological processes that Radix Rhei Et Rhizome may treat CI include platelet degranulation, cell migration, fibrinolysis, platelet activation, hypoxia, angiogenesis, endothelial cell apoptosis, coagulation, and neuronal apoptosis. The signaling pathways include Ras, PI3K-Akt, TNF, FoxO, HIF-1, and Rap1 signaling pathways. (2) Proteomics shows that the top 20 proteins in the differential protein PPI network were Syp, Syn1, Mbp, Gap43, Aif1, Camk2a, Syt1, Calm1, Calb1, Nsf, Nefl, Hspa5, Nefh, Ncam1, Dcx, Unc13a, Mapk1, Syt2, Dnm1, and Cltc. Differential protein enrichment results show that these proteins may be related to synaptic vesicle cycle, vesicle-mediated transport in synapse, presynaptic endocytosis, synaptic vesicle endocytosis, axon guidance, calcium signaling pathway, and so on. Conclusion. This study combined network pharmacology and proteomics to explore the main material basis of Radix Rhei Et Rhizome for the treatment of CI such as sennoside A, palmidin A, emodin, and toralactone. The mechanism may be related to the regulation of biological processes (such as synaptic vesicle cycle, vesicle-mediated transport in synapse, presynaptic endocytosis, and synaptic vesicle endocytosis) and signaling pathways (such as Ras, PI3K-Akt, TNF, FoxO, HIF-1, Rap1, and axon guidance).

Published: September 2021

Totaling at 7.4 billion people, the world’s population is rapidly growing, bringing along with it an increase in waste generation. The impact of this exponential increase in waste generation has resulted in the increased formation and utilization of landfills. In the present day, landfills are utilized to dispose of chemical, hazardous, municipal, and electronic wastes. However, despite their convenience, most landfills are improperly managed and face constant changes from the surrounding environment that interfere with their internal landfill processes. The objectives of this mixed review are to highlight the negative impacts landfills have on the environment and public health as well as outline the need for proper management practices to mitigate these effects. Inadequate management of landfills leads to issues concerning leachate collection and landfill gas (LFG) generation, which give rise to groundwater contamination and air pollution. This paper recognizes the disadvantages of utilizing landfills as the main disposal method by focusing on these two primary effects that improper management of landfills has on the environment and human health. Many experts have also reported that communities within close proximity to improperly managed landfills have an increased risk of health issues. Apart from implementing proper landfill management practices, it is important to develop solutions to reduce waste generation altogether. This review discusses some of the innovative methods implemented by other countries to reduce landfill waste and the production of greenhouse gases as well as possible steps individuals can take to minimize their ecological footprints.
Integrity Evaluation of a Reactor Pressure Vessel Based on a Sequential Abaqus-FRANC3D Simulation Method
Authors: Annor-Nyarko M. , Xia Hong
Published: September 2021

The safety-risk pressurized thermal shock (PTS) have on a reactor pressure vessel (RPV) is one of the most important studies for the lifetime ageing management of a reactor. Several studies have investigated PTS induced by postulated accidents and other anticipated transients. However, there is no study that analyzes the effect of PTS induced by one of the most frequent anticipated operational occurrences—inadvertent operation of the safety injection system. In this paper, a sequential Abaqus-FRANC3D simulation method is proposed to study the integrity status of an ageing pressurized water reactor subjected to PTS induced by inadvertent actuation of the safety injection system. A sequential thermal-mechanical coupling analysis is first performed using a three-dimensional reactor pressure vessel finite element model (3D-FEM). A linear elastic fracture mechanics submodel with a postulated semielliptical surface crack is then created from the 3D-FEM. Subsequently, the submodel is used to evaluate the stress intensity factors based on the M-integral approach coupled within the proposed simulation method. Finally, the stress intensity factors (SIFs) obtained using the proposed method are compared with the conventional extended finite element method approach, and the result shows a good agreement. The maximal thermomechanical stress concentration was observed at the inlet nozzle-inner wall intersection. In addition, The ASME fracture toughness of the reactor vessel’s steel compared with SIFs show that the PTS event and crack configuration analysed may not pose a risk to the integrity of the RPV. This work serves as a critical reference for the ageing management and fatigue life prediction of reactor pressure vessels.

Authors: Jampana Venkata N. Raju , Ramana Rao P. S. V. , Sampathkumar A.
Published: September 2021

Electric discharge machining (EDM) process is one of the earliest and most extensively used unconventional machining processes. It is a noncontact machining process that uses a series of electric discharges to remove material from an electrically conductive workpiece. This article is aimed to do a comprehensive experimental and thermal investigation of the EDM, which can predict the machining characteristic and then optimize the output parameters with a newly integrated neural network‐based methodology for modelling and optimal selection of process variables involved in powder mixed EDM (PMEDM) process. To compare and investigate the effects caused by powder of differently thermo physical properties on the EDM process performance with each other as well as the pure case, a series of experiments were conducted on a specially designed experimental setup developed in the laboratory. Peak current, pulse period, and source voltage are selected as the independent input parameters to evaluate the process performance in terms of material removal rate (MRR) and surface roughness (Ra). In addition, finite element method (FEM) is utilized for thermal analysis on EDM of stainless‐steel 630 (SS630) grade. Further, back propagated neural network (BPNN) with feed forward architecture with analysis of variance (ANOVA) is used to find the best fit and approximate solutions to optimization and search problems. Finally, confirmation test results of experimental MRR are compared using the values of MRR obtained using FEM and ANN. Similarly, the test results of experimental Ra also compared with obtained Ra using ANN.

Authors: Maslovara Sinisa , Kosec Andro , Pajic Matic Ivana , Sestak Anamarija
Published: September 2021

A rare case of a 38-year-old female patient who developed benign paroxysmal positional vertigo (BPPV) three weeks after head trauma is presented. The disease manifested bilaterally, which is not uncommon posttraumatically, but in this case, it manifested itself as canalithiasis of the posterior canal on both sides and cupulolithiasis of the right lateral canal, which to our knowledge is a unique and, until now, unpublished case. The aim of this review is to point out the fact that, in such a complex multicanal and bilateral clinical presentation of BPPV, it is not sufficient to perform only positioning but also additional laboratory tests. With a good knowledge of the etiopathogenesis, pathophysiology and clinical forms of BPPV, we can, in most cases, make an accurate and precise diagnosis of the disease and carry out appropriate treatment.
Experimental Study on the Damage and Deterioration Behaviour of Deep Soft Rock under Water-Rock Interaction
Authors: Zhao Zenghui , Liu Hao , Lyu Xianzhou , Wang Lei , Tian Zhongxi , Sun Jiecheng
Published: September 2021

The ageing disintegration, the damage, and failure mechanism of water-saturated soft rock are of significance to hazard prevention for deep mining. In this paper, indoor experiments, including disintegration behaviour tests in water, uniaxial compression failure tests of rock samples with different water contents, and variations in the microstructure of mudstone under saturated water contents, were conducted. The investigation results show that the saturated water content of mudstone is 16.96% and that the rock mass bursts completely after being immersed in water for 72 h. With increasing water content, the uniaxial strength and elastic modulus at the prepeak stage present significant attenuation. However, Poisson’s ratio varies little, which indicates that the swelling of cemented mudstone is not obvious when meeting water. In addition, the failure pattern of mudstone changes from overall splitting failure to block fragmentation failure. Due to ion-exchange adsorption and the wedging action of water molecules, the edge of contact between particles changes from staggered to smooth, which leads to the expansion of pores, the loosening of mudstone structures, and a decrease in mechanical strength. Therefore, the diffusion, migration, and particle expansion of illite and other clay minerals in mudstone are the main factors leading to the structural damage and strength reduction of weakly cemented rock under water-rock interactions.
An Improved Method for Multisensor High Conflict Data Fusion
Authors: Wang Like , Bao Yu
Published: September 2021

Dempster‐Shafer evidence theory can effectively process imperfect information and is widely used in a data fusion system. However, classical Dempster‐Shafer evidence theory involves counter‐intuitive behaviors with the data of multisensor high conflict in target identification system. In order to solve this problem, an improved evidence combination method is proposed in this paper. By calculating the support degree and the belief entropy of each sensor, the proposed method combines conflict evidences. A new method is used to calculate support degree in this paper. At the same time, inspired by Deng entropy, the modified belief entropy is proposed by considering the scale of the frame of discernment (FOD) and the relative scale of the intersection between evidences with respect to FOD. Because of these two modifications, the effect has been improved in conflict data fusion. Several methods are compared and analyzed through examples. And the result suggests the proposed method can not only obtain reasonable and correct results but also have the highest fusion reliability in solving the problem of high conflict data fusion.
Prediction of Bench Blasting Vibration on Slope and Safety Threshold of Blasting Vibration Velocity to Undercrossing Tunnel
Authors: He Li , Zhong Dongwang , Liu Yihe , Song Kun
Published: September 2021

The reconstruction and expansion project of oil reserve base often faces the excavation and blasting of the slope and undercrossing tunnel at the same time. Due to the flammable and explosive liquid storage nearby, the tight construction period, and the high requirements of collaborative construction, once the blasting accident occurs, the consequences are unimaginable. To facilitate safe and timely cooperative blasting construction of the slope and undercrossing tunnel, a vibration monitoring test of the slope and tunnel surrounding rock is conducted. The vibration response characteristics of the rock surrounding the slope and tunnel are analyzed, and a mathematical prediction model for the peak particle velocity (PPV) with consideration of the influence of the relative slope gradient (H/D) is established based on dimension analysis theory, which improves the prediction accuracy of PPV at the slope surface. ANSYS/LS‐DYNA is used to establish a 3D finite element model for the slope and tunnel, and the dynamic response of the tunnel surrounding rock under blasting load is verified through field monitoring data. A linear statistical relationship between PPV and effective tensile stress (ETS) of the tunnel surrounding rock is established. The PPV safety criterion of the tunnel surrounding rock under blasting load is proposed to be 10 cm/s according to the first strength theory, and hence, the minimum safety distance from the tunnel working face to the slope surface is calculated to be 36 m. Finally, the excavation timing arrangement of the slope and tunnel is proposed, which has been successfully applied to the expansion project, and the construction period has been effectively shortened by 45 days while ensuring construction safety. The research results have great guiding significance to similar cooperative blasting excavation engineering for high slope and adjacent tunnel with safety and efficiency.

Published: September 2021

Therapies targeting the tyrosine kinase receptor HER2 have significantly improved survival of patients with HER2+ cancer. However, both de novo and acquired resistance remain a challenge, particularly in the brain metastatic setting. Here we report that, unlike other HER tyrosine kinase receptors, HER2 possesses a binding motif in its cytosolic juxtamembrane region that allows interaction with members of the Ezrin/Radixin/Moesin (ERM) family. Under physiologic conditions, this interaction controls the localization of HER2 in ERM-enriched domains and stabilizes HER2 in a catalytically repressed state. In HER2+ breast cancers, low expression of Moesin correlated with increased HER2 expression. Restoring expression of ERM proteins in HER2+ breast cancer cells was sufficient to revert HER2 activation and inhibit HER2-dependent proliferation. A high-throughput assay recapitulating the HER2–ERM interaction allowed for screening of about 1,500 approved drugs. From this screen, we found Zuclopenthixol, an antipsychotic drug that behaved as a Moesin-mimicking compound, because it directly binds the juxtamembrane region of HER2 and specifically inhibits HER2 activation in HER2+ cancers, as well as activation of oncogenic mutated and truncated forms of HER2. Zuclopenthixol efficiently inhibited HER2+ breast tumor progression in vitro and in vivo and, more importantly, showed significant activity on HER2+ brain tumor progression. Collectively, these data reveal a novel class of allosteric HER2 inhibitors, increasing the number of approaches to consider for intervention on HER2+ breast cancers and brain metastases.

Significance:

This study demonstrates the functional role of Moesin in maintaining HER2 in a catalytically repressed state and provides novel therapeutic approaches targeting HER2+ breast cancers and brain metastasis using Moesin-mimicking compounds.

Authors: Cavaco Daniela Rodrigues , Alves Rafael Ana , Cabrera Rafael , Vilar Helena , Leite Valeriano
Published: September 2021

Diffuse thyroid lipomatosis is a rare histopathological condition of unknown etiology, characterized by diffuse fatty infiltration of the thyroid stroma, which can result in diffuse goiter with compressive symptoms. We report a case of a 46-year-old man with 1-year history of progressive goiter enlargement with compressive symptoms. Imaging studies revealed multiple coalescent nodules. The patient underwent surgery, and the microscopic appearance revealed a diffuse infiltration of thyroid stroma by mature adipose tissue with associated amyloid deposition. A final diagnosis of diffuse lipomatosis of the thyroid gland was established. This patient represents one of the few reported cases of diffuse lipomatosis with coexisting deposition of amyloid protein of the thyroid gland and contributes to the better understanding of this extremely rare condition.
Jak1/Stat3 Activation Alters Phosphate Metabolism Independently of Sex and Extracellular Phosphate Levels
Authors: Gehring Nicole , Bettoni Carla , Wagner Carsten A. , Rubio-Aliaga Isabel
Published: September 2021

Introduction: Phosphate homeostasis is regulated by a complex network involving the parathyroid hormone (PTH), fibroblast growth factor 23 (FGF23), and calcitriol acting on several organs including the kidney, intestine, bone, and parathyroid gland. Previously, we showed that activation of the Janus kinase 1 (Jak1)-signal transducer and activator of transcription 3 (Stat3) signaling pathway leads to altered mineral metabolism with higher FGF23 levels, lower PTH, and higher calcitriol levels. Here, we investigated if there are sex differences in the role of Jak1/Stat3 signaling pathway on phosphate metabolism and if this pathway is sensitive to extracellular phosphate alterations. Methods: We used a mouse model (Jak1S645P+/−) that resembles a constitutive activating mutation of the Jak1/Stat3 signaling pathway in humans and analyzed the impact of sex on mineral metabolism parameters. Furthermore, we challenged Jak1S645P+/− male and female mice with a high (1.2% w/w) and low (0.1% w/w) phosphate diet and a diet with phosphate with organic origin with lower bioavailability. Results: Female mice, as male mice, showed higher intact FGF23 levels but no phosphaturia, and higher calcitriol and lower PTH levels in plasma. A phosphate challenge did not alter the effect of Jak1/Stat3 activation on phosphate metabolism for both genders. However, under a low phosphate diet or a diet with lower phosphate availability, the animals showed a tendency to develop hypophosphatemia. Moreover, male and female mice showed similar phosphate metabolism parameters. The only exception was higher PTH levels in male mice than those in females. Discussion/Conclusion: Sex and extracellular phosphate levels do not affect the impact of Jak1/Stat3 activation on phosphate metabolism.

Authors: Farhat Wassim , Pariente Aaron , Mijahed Rami
Published: September 2021

Nitrous oxide, colloquially known as “whippets,” is a commonly abused inhalant by adolescents and young adults. There are limited data describing the adverse effects of this abuse. We present a 16-year-old girl with no medical history who presented to the emergency department for confusion, hallucinations, weakness, and headaches. Imaging revealed extensive cerebral thrombosis. She had no prior history of venous or arterial thrombosis. Hypercoagulability workup demonstrated an elevated homocysteine level. She was treated with effective anticoagulation and vitamin B12 folate supplementation. To our knowledge, there are a very few cases in the medical literature of cerebral venous thrombosis following the use of nitrous oxide. The pathophysiology of the disorder appears to be linked to the metabolism of vitamin B12 inducing hyperhomocysteinemia and a procoagulant state.

Published: September 2021

Background:

Ischemic and hemorrhagic cerebrovascular accidents remain common among patients with centrifugal-flow left ventricular assist devices, despite improvements in survival and device longevity. We compared the incidence of neurologic adverse events (NAEs) associated with 2 contemporary centrifugal-flow left ventricular assist devices: the Abbott HeartMate3 (HM3) and the Medtronic HeartWare HVAD (HVAD).

Methods:

Using the Society of Thoracic Surgeons Interagency Registry for Mechanically Assisted Circulatory Support (Intermacs), we collected data on adult patients who received a centrifugal-flow left ventricular assist device as a primary isolated implant between January 1, 2017, and September 30, 2019. Major NAEs were defined as transient ischemic attack, ischemic cerebrovascular accident, or hemorrhagic cerebrovascular accident. The association of HVAD with risk of NAE in the first year after implant was evaluated using propensity score matching to balance for preimplant risk factors. After matching, freedom from first major NAE in the HM3 and HVAD cohorts was compared with Kaplan-Meier curves. A secondary analysis using multivariable multiphase hazard models was used to identify predictors of NAE, which uses a data-driven parametric fit of the early declining and constant phase hazards and the associations of risk factor with either phase.

Results:

Of 6205 included patients, 3129 (50.4%) received the HM3 and 3076 (49.6%) received the HVAD. Median follow-up was 9 and 12 months (HM3 and HVAD, respectively). Patients receiving HVAD had more major NAEs (16.4% versus 6.4%,
P
<0.001) as well as each subtype (transient ischemic attack: 3.3% versus 1.0%,
P
<0.001; ischemic cerebrovascular accident: 7.7% versus 3.4%,
P
<0.001; hemorrhagic cerebrovascular accident: 7.2% versus 2.0%,
P
<0.001) than did patients receiving HM3. A propensity-matched cohort balanced for preimplant risk factors showed that HVAD was associated with higher probabilities of major NAEs (% freedom from NAE 82% versus 92%,
P
<0.001). Device type was not significantly associated with NAEs in the early hazard phase, but HVAD was associated with higher incidence of major NAEs during the constant hazard phase (hazard ratio, 5.71 [CI, 3.90–8.36]).

Conclusions:

HM3 is associated with lower hazard of major NAEs than is HVAD beyond the early postimplantation period and during the constant hazard phase. Defining the explanation for this observation will inform device selection for individual patients.
Fishing for Genes: How the Largest Gene Family in the Mammalian Genome was Found (and Why Idiosyncrasy in Exploration Matters)
Authors: Barwich Ann-Sophie
Published: September 2021

In 1991, Linda Buck and Richard Axel identified the multigene family expressing odor receptors. Their discovery transformed research on olfaction overnight, and Buck and Axel were awarded the 2004 Nobel Prize in Physiology or Medicine. Behind this success lies another, less visible study about the methodological ingenuity of Buck. This hidden tale holds the key to answering a fundamental question in discovery analysis: What makes specific discovery tools fit their tasks? Why do some strategies turn out to be more fruitful than others? The fit of a method with an experimental system often establishes the success of a discovery. However, the underlying reasoning of discovery is hard to codify. These difficulties point toward an element of discovery analysis routinely sidelined as a mere biographical element in the philosophical analysis of science: the individual discoverer’s role. I argue that the individual researcher is not a replaceable epistemic element in discovery analysis. This article draws on contemporary oral history, including interviews with Buck and other actors key to developments in late 1980s olfaction.
Biological Control Variously Materialized: Modeling, Experimentation and Exploration in Multiple Media
Authors: Knuuttila Tarja , Loettgers Andrea
Published: September 2021

This paper examines two parallel discussions of scientific modeling which have invoked experimentation in addressing the role of models in scientific inquiry. One side discusses the experimental character of models, whereas the other focuses on their exploratory uses. Although both relate modeling to experimentation, they do so differently. The former has considered the similarities and differences between models and experiments, addressing, in particular, the epistemic value of materiality. By contrast, the focus on exploratory modeling has highlighted the various kinds of exploratory functions of models in the early stages of inquiry. These two perspectives on modeling are discussed through a case study in the field of synthetic biology. The research practice in question explores biological control by making use of an ensemble of different epistemic means: mathematical models and simulations, synthetic genetic circuits and intracellular measuring devices, and finally electronic circuits. We argue that the study of exploratory modeling should trace the ways different epistemic means, in different materialities, are being combined over time. Finally, the epistemic status of such novel investigative objects as synthetic genetic circuits is evaluated, with the conclusion that they can function as both experiments and models.

Also, the change of green infrastructure represents the increased demand for experience that reflects the need and expectation for nature. Conclusion The new trend of green Infrastructure in the pandemic era should be considered in the the individual relaxations & activities.
The effects of habituation on boldness of urban and rural song sparrows (Melospiza melodia)
Authors: Fossett Taylor Elaine , Hyman Jeremy
Published: September 2021

As urbanization increases globally, wildlife species are changing their behaviour in many ways. Urban animals are often bolder, or less fearful of new stimuli, than rural animals. While adaptation can drive behavioural changes in urban animals, other factors, such as learning or habituation, can also lead to behavioural modifications. To determine how repeated exposure to a non-threatening human affects song sparrow (Melospiza melodia) behaviour in urban and rural habitat, we measured boldness as flight initiation distance (FID), for 5 consecutive days. We found that urban birds had consistently lower FID’s than their rural counterparts from days 1–4, yet there was no difference in rural and urban FID by trial 5. FID decreased over 5 days of repeated trials in the rural populations, but not the urban. These results suggest that habituation can occur quickly in rural birds and may account for the greater boldness we typically see in urban populations.

Poverty Assessment for Reorienting Poverty Alleviation Programmes in the Forest Fringe Area of Madhya Pradesh, India
Authors: Yadava Ram Nayan , Sinha Bhaskar
Published: September 2021

The present study attempts to assess poverty using two commonly used indices namely Progress out of Poverty Index (PPI) and Progress out of Deprivation Index (PDI or DI) of 325 households, spread in twenty-nine villages of Hoshangabad and Mandla districts of Madhya Pradesh, India. The analysis of PPI and PDI scores showed that the poverty of a household/community decreases as their level of the economy, occupation and education improve, irrespective of their social class to which the household/community belongs. With this finding, it is recommended that prioritisation of the beneficiaries of programmes and policies related to poverty eradication in the forest fringe villages should not be based on caste or social class, but on household’s occupation, economy and education.

Published: September 2021

Researchers have suggested that people with refugee status have heightened rates of western-defined psychiatric symptoms. Following this evidence, treatments have been adapted with the intent to foster culturally competent service provision for members of refugee communities. Absent in this research is attention to how clinicians address diverse beliefs about illness constructed within the cultures of refugee individuals. As such, even adapted treatments may not readily integrate beliefs about illness espoused in these communities into counseling. The purpose of this descriptive phenomenological study was to explore the meaning mental health care providers ascribe to integrating refugee individuals’ cultural beliefs about illness and treatment into counseling. Interviews ( N = 8) were analyzed accordant with descriptive phenomenology. Four themes were identified: (a) Presenting Concerns, Stigma, and Expectations, (b) Centering Diverse Explanations of Distress, (c) Shifting the Work to Connect, and (d) Language as Barrier and Opportunity. The themes represent the meaning that participants ascribed to focusing on what their clients from refugee communities bring to treatment and the value of centering their explanations of distress. Further, they expressed the clinical value of changing how they work and the difficulty as well as benefit of language in treatment. The value of integrating diverse illness beliefs into counseling from a multiculturally oriented perspective is discussed.
Barriers and Supports Experienced by Pacific Peoples in Aotearoa New Zealand’s Mental Health Services
Authors: Fa’alogo-Lilo Christina , Cartwright Claire
Published: September 2021

As with minority groups internationally, Pacific peoples in New Zealand (Pasifika) experience higher rates of mental health problems than the general population, and are less likely to access mental health services. This study investigated the barriers and supports for Pasifika accessing and using mental health services with participation of 25 Pasifika (10 service-providers, 11 ex-service-users, and 4 ex-service-users/providers) in order to gain their key informant perspectives. A Pasifika-appropriate Talanoa approach was used to guide the data-collection process and the qualitative data were analyzed using thematic analysis. Barriers included stigma among Pasifika regarding mental health problems, commitment to finding solutions within the family, and both mistrust and lack of knowledge of services. Within the services, non-Pasifika providers often lacked understanding of the collectivist cultural values and practices of Pasifika, including spiritual beliefs. They were more likely to use services if the providers were respectful of Pasifika practices and paid attention to developing relationships in a culturally appropriate way. This included involvement of the Pasifika family, when possible. Service-users often benefited from contact with Pasifika providers within mainstream services. These results support previous cross-cultural research that indicates the importance of offering evaluation and intervention services grounded in an understanding and respect for the cultural significance and meaning of mental health problems for the person, the family, and their community. While efforts are made to address these issues in New Zealand, change is slow and ongoing cultural training for service-providers along with psychoeducation for Pasifika about mental health services is strongly desirable.

Published: September 2021

Background: Formulation and working psychologically with teams is considered a fundamental part of the role of a clinical psychologist. Quantitative studies have found staff find team formulations a positive, useful experience. Aims: This review aims to utilize a Thematic Synthesis to combine qualitative studies on staff experiences of participating in team formulations and explore what benefits staff perceive from the process. The review also aims to provide a thorough quality appraisal of the included research. Method: A Thematic Synthesis was completed on qualitative studies which met the required inclusion criteria. The Critical Appraisal Skills Programme qualitative checklist was used to appraise the included research. Results: The studies included in the review were of a mixed quality, and in some instances there was an insufficient amount of detail to complete an accurate assessment. Overall, seven themes were identified across the studies. Conclusions: The current review highlights the importance of team formulation in general practice for both enhancing staff understanding of service users but also improving professional confidence and validation. The review also highlighted some of the barriers to staff practicing team formulations.

In the research of breast morphology, numerous breast features are measured, whereas only a few parameters are adopted for classification. Therefore, how to extract the key variables from the multi-dimensional features in a rational way is an issue that is focused upon. This study aimed to reduce the complexity of the dimensionality reduction for further improving the objectivity and interpretability of the selected breast features. Since the random forest (RF) algorithm can quantify the feature importance during training, the method was adopted to determine the optimal breast features for classification and recognition in this paper. Firstly, the anthropometric data of 360 females from northwestern China aged from 19 to 27 years were measured by non-contact three-dimensional body scanning technology and the contact manual measurement method. Then, the k-means clustering was applied to categorize breast shapes, and the RF algorithm was utilized to quantify and rank the importance of 25 breast features. Finally, to verify the availability of the RF algorithm on breast feature selection, the t-distributed stochastic neighbor embedding method was adopted to visualize the distribution of breast shape clusters into two dimensions. Meanwhile, four neural networks were determined to recognize the breast morphology. The results demonstrate that fewer breast features can effectively increase the accuracy of breast shape classification and recognition. The best performance of breast shape classification and recognition is obtained when the number of breast features is 13. In this case, the average Hamming loss of four neural networks is the smallest (0.1136). Interestingly, the bust circumference and the horizontal curve of breasts across the bust points are found to be the most important of the 25 breast features in this paper. The importance of the breast curve features is higher than that of the breast cross-sectional features, while the breast positioning features have the lowest importance. Meanwhile, the RF algorithm is verified to be more effective than traditional dimensionality reduction methods, such as principal component analysis, hierarchical clustering, and recursive feature elimination. The approach developed in this paper can be generalized to the dimensionality reduction of other body morphology.
White Ecclesiology: The Identity of the Church in the Statements on Racism by United States Catholic Bishops
Authors: Flipper Joseph J.
Published: September 2021

The latest United States Conference of Catholic Bishops’ document on racism, Open Wide Our Hearts, prompted numerous criticisms. This article argues that US Catholic bishops’ statements on racism from 1958 to 2018 all too often present an image of the church in which Black, Latinx, Asian, and American Indian identities are spatially and socially the exterior, thereby constructing a white ecclesiology.
Social Protection Network Across Indian States
Authors: Deb Surajit
Published: September 2021

This contribution of the Social Change Indicators forms the eleventh part of the series. Over the last three segments, we have been focussing on the social and economic challenges arising out of the COVID-19 pandemic and lockdowns. The topics previously covered were on the themes of vulnerable households across social classes, poverty and migration and living conditions for social distancing. In this part, we highlight the spread of the social protection network in various states of India. Aspects such as the percentage of households having a below poverty line (BPL) card, percentage of households having a health scheme or health insurance, percentage of households having a bank or post office account, Aadhaar card saturation, percentage of families/persons covered under the targetted Public Distribution System, percentage of Aadhaar-seeded ration cards, allocation of work under MGNREGA (Mahatma Gandhi National Rural Employment Guarantee Act) and the number of fair price shops per thousand population in 2021 have been examined. The required data has been collected from the Aadhaar Saturation Report provided by the Unique Identification Authority of India, the Food Grain Bulletin of the Ministry of Consumer Affairs, Food and Public Distribution, Ration Card Dashboard of the National Food Security Act, the public data portal of MGNREGA and the Fourth Round of the National Family Health Survey’s state volumes.
Necrosis and amputation following the bite of the Bibron’s stiletto snake (Atractaspis bibronii) with a concise review of current literature

Atractaspis bibronii are highly specialised snakes found across Southern Africa. Adapted for subterranean hunting of prey, snakes of the genus Atractaspis demonstrate a unique biting mechanism, with an ability to deliver venom via a single fang, protruded over an almost closed mouth in a side-to-side striking pattern. It is not possible to handle these snakes safely. Atractaspididae can be mistaken for medically insignificant snakes and often occur in remote areas that may lead to delayed or reduced presentation to suitable care facilities. We here report a case of an A. bibronii envenomation in remote Southern Africa to the right ring finger from a single fang with significant complication. Medical, and subsequently, surgical management of a progression from discolouration at the bite site, to spreading oedema, blistering, local necrosis and secondary infection required amputation of the digit.

Consumption of news media can influence attitudes toward specific groups, but the influence of news media on longitudinal data collection has not yet been researched. We present a method to index media attention on a specific topic, as well as a case study on a big child sexual abuse (CSA) story and its effect on parents’ attitudes toward male childcare professionals in a longitudinal study with fathers and mothers of 207 Dutch families. Questionnaire data on attitudes toward gender-differentiated parenting were collected in four annual waves between 2010 and 2014. NexisUni® Academic database was used to index articles on CSA to chart patterns of media attention before and during that time span. There was an immediate increase in media attention, the amount of articles on CSA doubled, as well as a prolonged increase in attention which culminated during the second wave of the study. In the first wave, 97 of the families participated before the CSA case became known, and 110 participated afterward. Parents who participated after the first news about the case came out reported a more negative attitude toward hiring a male babysitter than those who participated before it. This effect was stronger for mothers. The negative effect on attitude endured during the subsequent waves for all fathers and for those mothers who participated before the news broke. Findings indicate that big news stories influence attitudes that lasts over time and can therefore influence longitudinal data. Further analysis suggests that the influence of news stories is gendered, as mothers showed a recovery in their attitudes over time while fathers did not. We recommend further research on the effect of news on attitude and behavioral measures in longitudinal research.
