Participant Observation, Observant Participation, and Hybrid Ethnography
Authors: Seim Josh
Published: February 2021

How much should ethnographers involve themselves with the people, places, and processes they study? One answer has become increasingly popular: invert the standard method of participant observation into observant participation. This article draws on an ethnography of ambulance work to consider the trade-offs between these approaches. My fieldwork included “ride-alongs” with labor and management at a private ambulance firm in California (participant observation) and short-term employment as a novice emergency medical technician at the same company (observant participation). Beyond a simplistic distinction in “empirical depth,” I identify three issues at stake between participant observation and observant participation: field positioning, analytic gaze, and data assembly. Where participant observation presents more opportunities for mobile positioning, outward gazing, and inscription, observant participation presents more opportunities for fixed positioning, inward gazing, and incarnation. In addition to justifying such contrasts, I consider the advantages of mixing these styles into a hybrid approach when feasible.

Published: February 2021

Primary cutaneous – diffuse large B-cell lymphoma – leg type (PC-DLBCL-LT) is a less frequent but more aggressive, and potentially curable, type of cutaneous B-cell lymphoma, with intermediate prognosis, that affects elderly individuals. Our patient with indurated, pigmented foot previously treated for Filariasis, now presented with ulcers, multiple discharging sinuses, clinically suspected to have Madura Foot. Histopathological examination confirmed a diagnosis of PC-DLBCL-LT after which he underwent below-knee amputation.
Suicidal behaviour among university students: a systematic review
Authors: Pillay Jace
Published: February 2021

A systematic literature review was conducted to explore worldwide prevalence studies on student suicide, the risks and protective factors related to student suicide, and university-based interventions to combat it. The search of four major databases identified 60 studies published in peer-reviewed academic journals between 2015 and 2020. Majority of these publications were from the United States, followed by China and the United Kingdom. Studies in South Africa and the African Continent as a whole were limited in terms of meeting the selection criteria of the review. The findings indicate that most of the publications ranged from describing suicide risk factors innate to students, such as their demographic and mental health features, to social and university stressors. Although the studies on protective factors were limited, several psychological, social, and behavioural elements to prevent student suicide were identified. I adopted the Three-Step Theory of suicide to discuss the implications of the findings by presenting several campus-based strategies to combat student suicides.

Published: February 2021

Objective

Catatonia is a disorder characterized by psychomotor symptoms. The etiology, symptomatology, response and outcome of catatonia in the medically ill has not been vigorously studied. Those who have catatonia associated with another mental disorder versus. catatonic disorder due to another medical condition may differ. The aim of this study is to study the causes, phenomenology and outcomes of medically ill patients with catatonia and explore differences among those who have catatonia associated with psychiatric illness vs. systemic medical illness.

Method

We studied the incidence of catatonic symptoms in medically hospitalized patients to identify any apparent differences in clinical manifestations due to distinctive etiologies. Specifically, we assessed if there are differences between those who had catatonia associated with another mental disorder versus those with catatonic disorder due to another medical condition in their phenomenology, management and likelihood of response to treatment.

Results

Of our 40 patients, 18 patients (45%) had catatonia associated with another mental disorder, 17 (42.5%) had catatonic disorder due to another medical condition, and in 5 patients (12.5%) the cause of catatonia was not identified. The most common catatonic symptoms regardless of etiology in our medically ill were mutism, followed by rigidity, and immobility. Bipolar disorder, schizophrenia, major depressive disorder, metabolic abnormalities, anti NMDAR encephalitis were the most frequent causes of catatonia in our medically ill patients. Compared to subjects with catatonic disorder due to another medical condition, those with catatonia associated with another mental disorder had more frequent mannerisms (Chi-square = 4.27; p = 0.039), waxy flexibility (Chi-square = 11.0; p < 0.01), and impulsivity (Chi-square = 4.12, p = 0.042). Nonsignificant trends were noted for posturing (Chi-square = 3.74, p = 0.053), perseveration (Chi-square = 3.37, p = 0.067), and stereotypy (Chi-square = 2.91, p = 0.088) also being more frequent in catatonia associated with a psychiatric cause.

Discussion

Our data supports phenomenological differences between medical and psychiatric causes of catatonia in the medically ill.
Violence and Moral Exclusion: Legitimizing Domestic Military Operations in Brazil
Authors: Junior David P. Succi
Published: February 2021

Many contemporary security issues entail the domestic military deployment, which is deemed to blur the division between armed forces and police. This argument relies on the theoretical coalescence between territory, political authority, and community. In contrast, I argue the military domestic deployment is largely grounded on the process of defining and redefining the boundaries of the community to be protected, which informs the organization of the instruments of force and is shaped throughout the process of legitimizing a particular kind of violence deployment. This article analyses the parliamentary minutes on three domestic military operations in Brazil—Operation Rio (1994), Operation Arcanjo (2010), and the Operation Rio de Janeiro (2017)—through the moral exclusion framework and shows that the debates about whether or not the armed forces should be deployed are embedded in the struggle of drawing the community’s boundaries.
The Labor Contract Law and the economic integration of rural migrants in urban China
Authors: Wu Yuling , Xiao Hong
Published: February 2021

This study examines the income determinants of rural migrants versus urban residents in the urban labor market of China during the 2008 Labor Contract Law era. We focus on the effects of employment contracts, enterprise ownership and social networks on income using data from the 2009 Rural-Urban Migration in China survey and applying ordinary least squares regression and propensity score matching analyses. The results showed that urban residents were more advantaged with guaranteed respectable job earnings, stable employment contracts and involvement in state-owned enterprises and public organizations compared to rural migrants. Rural migrants earned much less than their urban counterparts across ownership sectors. Although rural migrants benefited from urban networks, social exclusion impeded their accumulation of urban ties. Despite the Chinese Government’s call in recent years to fully support the citizenization of rural migrants by revising the Labor Contract Law and reforming the household registration ( hukou) system, the study showed that the integration of rural migrant workers in urban China has a long way to go.
Static grid carbon factors – Can we do better?
Authors: Risner Jamie , Sutherland Anna
Published: February 2021

The average carbon intensity (gCO2e/kWh) of electricity provided by the UK National Grid is decreasing and becoming more time variable. This paper reviews the impact on energy calculations of using various levels of data resolution (half hourly, daily, monthly and annual) and of moving to region specific data. This analysis is in two parts, one focused on the potential impact on Part L assessments and the other on reported carbon emissions for existing buildings.

Analysis demonstrated that an increase in calculated emissions of up to 12% is possible when using an emissions calculation methodology employing higher resolution grid carbon intensity data. Regional analysis indicated an even larger calculation discrepancy, with some regions annual emissions increasing by a factor of ten as compared to other regions.

This paper proposes a path forward for the industry to improve the accuracy of analysis by using better data sources. The proposed change in calculation methodology is analogous to moving from using an annual average external temperature to using a CIBSE weather profile for a specific city or using a future weather file.

Practical application: This paper aims to quantify the inaccuracy of a calculation methodology in common use in the industry and key to building regulations (specifically Building Regulations Part L – Conservation of Fuel and Power) – translating electricity consumption into carbon emissions. It proposes an alternative methodology which improves the accuracy of the calculation based on improved data inputs.
Hacking Humans? Social Engineering and the Construction of the “Deficient User” in Cybersecurity Discourses
Authors: Klimburg-Witjes Nina , Wentland Alexander
Published: February 2021

Today, social engineering techniques are the most common way of committing cybercrimes through the intrusion and infection of computer systems. Cybersecurity experts use the term “social engineering” to highlight the “human factor” in digitized systems, as social engineering attacks aim at manipulating people to reveal sensitive information. In this paper, we explore how discursive framings of individual versus collective security by cybersecurity experts redefine roles and responsibilities at the digitalized workplace. We will first show how the rhetorical figure of the deficient user is constructed vis-à-vis notions of (in)security in social engineering discourses. Second, we will investigate the normative tensions that these practices create. To do so, we link work in science and technology studies on the politics of deficit construction to recent work in critical security studies on securitization and resilience. Empirically, our analysis builds on a multi-sited conference ethnography during three cybersecurity conferences as well as an extensive document analysis. Our findings suggest a redistribution of institutional responsibility to the individual user through three distinct social engineering story lines—“the oblivious employee,” “speaking code and social,” and “fixing human flaws.” Finally, we propose to open up the discourse on social engineering and its inscribed politics of deficit construction and securitization and advocate for companies and policy makers to establish and foster a culture of collective cyber in/security and corporate responsibility.
Public Trust and Political Legitimacy in the Smart City: A Reckoning for Technocracy
Authors: Hartley Kris
Published: February 2021

The 2020 introduction by China’s central government of a national security law (NSL) in Hong Kong marked a watershed moment in the social and political history of the semiautonomous city. The law emerged after months of street protests that reflected declining public trust in Hong Kong’s government. Against this turbulent backdrop, Hong Kong’s policy projects moved forward, including smart city development. This article explores public trust in and political legitimacy of Hong Kong’s smart cities endeavors in the period leading up to the introduction of the NSL. At a theoretical level, the smart cities phenomenon invites critical reflection about tensions between technocracy and democracy, but this topic remains largely unexploited by empirical literature. Using survey data from 1,017 residents, this study identifies confidence in the benefits of smart cities but lesser trust in privacy and security and lesser satisfaction with participation opportunities in related policymaking. Probing these dynamics, the study finds that trust in smart city mechanics and governance associate positively with support for smart cities, controlling for ideology and issue awareness. Illuminating a theoretical and practical puzzle, these findings contribute empirically to discussions about the political legitimacy of scientific, technological, and technocratic undertakings in the public sector.
Parenting of Adolescent Single Children: A Mixed-methods Study
Authors: Khadaroo Ameerah , MacCallum Fiona
Published: February 2021

Globally, the average number of children per household is expected to drop to 1.0 by 2020. Single-child families are increasingly the norm, with nearly half of British families classified as single-child. Despite this, research on only-children and their families is scant. Using a convergent mixed-methods design, this study explores parenting of adolescents in British single-child families. Single-child (31 adolescents, 47 mothers, 25 fathers) and multiple-children families (46 adolescents, 76 mothers, 31 fathers) completed online surveys. In-depth interviews were also conducted with 15 only-child families and 15 multiple-child families. All adolescents were aged 11 years to 14 years. Surveys did not find any differences in parenting between one-child and multiple-children families. However, interview data found single-child families were more child-centered, reporting higher overprotective and pushy parenting, but less authoritative and authoritarian parenting. Findings challenge negative stereotyping of single-child families and provide an in-depth insight into the experiences of adolescent only-children and their parents.
Archaeological Methodology: Foucault and the History of Systems of Thought
Authors: Krarup Troels
Published: February 2021

Existing accounts of Foucault’s archaeological methodology have not (a) contextualized the concept properly within the intellectual field of its emergence and (b) explained why it is called ‘archaeology’ and not simply ‘history’. Foucault contributed to the field of ‘history of systems of thought’ in France around 1960 by broadening its scope from the study of scientific and philosophical systems into systems of ‘knowledge’ in a wider sense. For Foucault, the term ‘archaeology’ provided a response to new methodological questions arising from this initiative. Archaeological methodology had already been developed into a distinct comparative approach for the study of linguistic and cultural systems, notably by Dumézil. Foucault redevised archaeological methodology for the post-Hegelian tradition of studying ‘problems’ prevalent in the history of systems of thought. The article thus furnishes the groundwork for a ‘sociological archaeology’ or ‘problem analysis’ that is not particularly dependent on Foucault as a social theorist of power.
The functional ability of older adults with visual impairments: A 2-year follow-up study
Authors: Saarela Kaisa-Mari Mirjam , Jämsä Ulla , Falck Aura , Kyngäs Helvi , Siira Heidi Johanna
Published: February 2021

This study describes the self-estimated functional ability of older adults with visual impairments (VI) living at home prior to and after 24 months of individual low vision rehabilitation (LVR) according to the International Classification of Functioning, Disability and Health (ICF) framework. The LVR was carried out according to regular standard of care in Finland. The study provides knowledge that is relevant for improving both LVR as well as other services for older adults living with VI. Thirty-nine older adults with VI initially participated in the study with 28 remaining for the follow-up at 24 months of LVR. Data were collected by an orally administered questionnaire including items from the Oldwellactive Wellness Profile instrument. Data were analyzed using the marginal homogeneity test, and the outcomes were divided into four categories according to the ICF framework. Comparisons between the baseline and 2-year follow-up revealed statistically significant decreases in daily functions, including going outdoors ( p = .011), washing oneself ( p = .016), taking care for personal hygiene ( p = .046), dressing ( p = .034), preparing meals ( p = .041), and doing heavy housework ( p = .046), following 2 years of received LVR. A statistically significant increase in the need for help was also observed during the study period ( p = .025). The independence of older adults with VI decreased, and the need for external services or help increased during 24 months after the onset of receiving LVR. Visual problems were shown to widely affect functional ability. Activities and participation dimension together with loneliness are most affected and need attention in individual LVR.

Published: February 2021

Introduction:

Extracorporeal life support (ECLS) patients are at risk for complications caused by gaseous microemboli (GME). GMEs can cause hypoxia, inflammation, coagulation, and end-organ damage. The objective of this in vitro study was to assess dynamics of GME formation during circulation of whole blood or a glycerol blood surrogate. We hypothesized that there is no difference in GME counts and sizes between whole blood and the glycerol blood surrogate and that the membrane lung reduces GME counts over time.

Methods:

A circulation platform was developed using the Cardiohelp ECLS system to run either donor blood or glycerol solution. We conducted 10 repetitions consisting of three phases of ultrasound GME detection using the EDAC™ Quantifier (Luna Innovations, Charlottesville, VA, USA) for each group. Phases were 3-minute recordings at the initiation of 2 L/min flow (Phase 1), post-injection of a GME suspension (Phase 2), and 10 minutes after injection (Phase 3). The number and size of GME pre- and post-ML were recorded separately and binned based on diameter ranges.

Results:

In Phase 1, GME count in blood was higher than in glycerol. In Phase 2, there was a large increase in GME counts; however, most GME were reduced post-membrane in both groups. In Phase 3, there was a significant decrease in GME counts compared to Phase 2. GME > 100 μm in glycerol decreased post membrane.

Conclusions:

We demonstrated GME formation and decay dynamics during in vitro circulation in an ECLS system with blood and glycerol. GME counts were higher in blood, likely due to varying rheological properties. There were decreases in GME levels post membrane in both groups after GME injection, with the membrane lung effectively trapping the GME, and additional reduction 10 minutes after GME injection.
Human perceptual learning is delayed by the N-methyl-D-aspartate receptor partial agonist D-cycloserine

Published: February 2021

Background:

The optimisation of learning has long been a focus of scientific research, particularly in relation to improving psychological treatment and recovery of brain function. Previously, partial N-methyl-D-aspartate agonists have been shown to augment reward learning, procedural learning and psychological therapy, but many studies also report no impact of these compounds on the same processes.

Aims:

Here we investigate whether administration of an N-methyl-D-aspartate partial agonist (D-cycloserine) modulates a previously unexplored process – tactile perceptual learning. Further, we use a longitudinal design to investigate whether N-methyl-D-aspartate-related learning effects vary with time, thereby providing a potentially simple explanation for apparent mixed effects in previous research.

Methods:

Thirty-four volunteers were randomised to receive one dose of 250 mg D-cycloserine or placebo 2 h before tactile sensitivity training. Tactile perception was measured using psychophysical methods before and after training, and 24/48 h later.

Results:

The placebo group showed immediate within-day tactile perception gains, but no further improvements between-days. In contrast, tactile perception remained at baseline on day one in the D-cycloserine group (no within-day learning), but showed significant overnight gains on day two. Both groups were equivalent in tactile perception by the final testing – indicating N-methyl-D-aspartate effects changed the timing, but not the overall amount of tactile learning.

Conclusions:

In sum, we provide first evidence for modulation of perceptual learning by administration of a partial N-methyl-D-aspartate agonist. Resolving how the effects of such compounds become apparent over time will assist the optimisation of testing schedules, and may help resolve discrepancies across the learning and cognition domains.
Perfusion imaging-based tissue-level collaterals predict ischemic lesion net water uptake in patients with acute ischemic stroke and large vessel occlusion

Ischemic lesion Net Water Uptake (NWU) quantifies cerebral edema formation and likely correlates with the microvascular perfusion status of patients with acute ischemic stroke due to large vessel occlusion (AIS-LVO). We hypothesized that favorable tissue-level collaterals (TLC) predict less NWU and good functional outcomes. We performed a retrospective multicenter analysis of AIS-LVO patients who underwent thrombectomy triage. TLC were measured on cerebral perfusion studies using the hypoperfusion intensity ratio (HIR; volume ratio of brain tissue with [Tmax > 10 sec/Tmax > 6 sec]); favorable TLC were regarded as HIR [Formula: see text] 0.4. NWU was determined using a quantitative densitometry approach on follow-up CT. Primary outcome was NWU. Secondary outcome was a good functional outcome (modified Rankin Scale [mRS] 0–2).

580 patients met inclusion criteria. Favorable TLC ( β: 4.23, SE: 0.65; p < 0.001) predicted smaller NWU after treatment. Favorable TLC (OR: 2.35, [95% CI: 1.31–4.21]; p < 0.001), and decreased NWU (OR: 0.75, [95% CI: 0.70–0.79]; p < 0.001) predicted good functional outcome, while controlling for age, glucose, CTA collaterals, baseline NIHSS and good vessel reperfusion status.

We conclude that favorable TLC predict less ischemic lesion NWU after treatment in AIS-LVO patients. Favorable TLC and decreased NWU were independent predictors of good functional outcome.
Metabolomic and transcriptional profiling reveals bioenergetic stress and activation of cell death and inflammatory pathways in vivo after neuronal deletion of NAMPT

Published: February 2021

Nicotinamide phosphoribosyltransferase (NAMPT) is the rate-limiting enzyme in the NAD+ salvage pathway. Our previous study demonstrated that deletion of NAMPT gene in projection neurons using Thy1-NAMPT−/− conditional knockout (cKO) mice causes neuronal degeneration, muscle atrophy, neuromuscular junction abnormalities, paralysis and eventually death. Here we conducted a combined metabolomic and transcriptional profiling study in vivo in an attempt to further investigate the mechanism of neuronal degeneration at metabolite and mRNA levels after NAMPT deletion. Here using steady-state metabolomics, we demonstrate that deletion of NAMPT causes a significant decrease of NAD+ metabolome and bioenergetics, a buildup of metabolic intermediates upstream of glyceraldehyde 3-phosphate dehydrogenase (GAPDH) in glycolysis, and an increase of oxidative stress. RNA-seq shows that NAMPT deletion leads to the increase of mRNA levels of enzymes in NAD metabolism, in particular PARP family of NAD+ consumption enzymes, as well as glycolytic genes Glut1, Hk2 and PFBFK3 before GAPDH. GO, KEGG and GSEA analyses show the activations of apoptosis, inflammation and immune responsive pathways and the inhibition of neuronal/synaptic function in the cKO mice. The current study suggests that increased oxidative stress, apoptosis and neuroinflammation contribute to neurodegeneration and mouse death as a direct consequence of bioenergetic stress after NAMPT deletion.

Published: February 2021

Objective

This study aimed to examine whether addition of cervical elastographic parameters measured by ElastoScan for the cervix (E-cervix) improves the predictive value of cervical length (CL) in induction of labor at term by dinoprostone.

Methods

We conducted a prospective, observational study between January 2020 and June 2020 in term primiparous women (n = 73) who were scheduled for labor induction by a 10-mg dinoprostone vaginal insert. The time intervals from the start of labor induction to regular uterine contractions and to vaginal delivery were calculated as the primary outcomes. We divided subjects into two groups using a threshold of 24 hours. Ultrasound measurements were compared between the two groups and the area under the curve (AUC) of the prediction model was calculated.

Results

Women who delivered vaginally within 24 hours had a shorter CL and softer cervix than those who delivered after 24 hours. The combination of CL and elastographic parameters increased the AUC to 0.672 compared with CL alone (AUC = 0.637).

Conclusions

Measurement by E-cervix is relatively reproducible. Addition of cervical strain elastography slightly improves the predictive performance of CL in vaginal delivery within 24 hours. This technique is a promising ancillary tool for use with ultrasound.
Cutaneous Spindle Cell Squamous Cell Carcinoma in Cats: Clinical, Histological, and Immunohistochemical Study
Authors: Rodríguez Guisado Francisco , Suárez-Bonnet Alejandro , Ramírez Gustavo A.
Published: February 2021

This study describes the clinical and pathological characteristics of cutaneous spindle cell squamous cell carcinoma (SCSCC) in 18 cats. The average age of the cats was 11.8 ± 2.7 years, and all tumors were located in the facial skin, mainly affecting the pinna (13/18, 72%), followed by the periorbital area (4/18, 22%) and the dorsal muzzle (1/18, 6%). Tumors were composed of fusiform neoplastic cells with moderate atypia arranged in solid sheets or fascicles with foci of squamous differentiation. A panel of antibodies against cytokeratins, vimentin, S-100 protein, NSE, GFAP, Melan A, SMA, desmin, CD18, CD31, and p63 was used to help differentiate SCSCC from other spindle cell malignancies. SCSCCs expressed CK5/6 (17/18, 94%), AE1/AE3 (15/18, 83%), and p63 protein (18/18, 100%), but there was no immunolabeling for CK8/18. A role for sunlight exposure in the pathogenesis of the tumors was suggested by changes indicative of actinic keratosis, the location of the tumors in dorsal areas, and the absence of histomorphologic features of papillomavirus infection. Recurrence was not recorded in 14/18 cases (78%) during a follow-up period of 7 to 25 months. Three of 18 (17%) tumors recurred or led to humane euthanasia due to local progression, and one case (5%) had regional lymph node metastasis. Clinical outcome varied with cutaneous location, mitotic count, and invasion of surgical margins; thus, SCSCCs with a more aggressive behavior were located in the periorbital area (4/4 cases), had ≥14 mitoses in 10 high-power fields (2.37 mm2) (4/4 cases), and showed invasion of surgical margins (3/4 cases).

Published: February 2021

Canine cutaneous mast cell tumors (ccMCTs) are currently graded according to Patnaik and Kiupel grading schemes. The qualitative and semiquantitative parameters applied in these schemes may lead to inter- and intraobserver variability. This study investigates the prognostic value of volume-weighted mean nuclear volume ([Formula: see text]), a stereological estimation that provides information about nuclear size and its variability. [Formula: see text] of 55 ccMCTs was estimated using the “point-sampled intercept” method and compared with histological grade and clinical outcome. The clinical history of dogs treated with surgical excision alone was available for 30 ccMCTs. Statistical differences in [Formula: see text] were found between grade II ([Formula: see text]= 115 ± 29 µm3) and grade III ccMCTs ([Formula: see text]= 197 ± 63 µm3), as well as between low-grade ([Formula: see text]= 113 ± 28 µm3) and high-grade ccMCTs ([Formula: see text]= 184 ± 63 µm3). An optimal cutoff value of [Formula: see text] ≥ 150 µm3 and [Formula: see text] ≥ 140 µm3 was determined for grade III and high-grade ccMCTs, respectively. In terms of prognosis, [Formula: see text] was not able to predict the clinical outcome in 42% of the cases; however, cases with [Formula: see text]<125 µm3 had a favorable outcome. These results indicate that, despite having limited prognostic value when used as a solitary parameter, [Formula: see text] is highly reproducible and is associated with histological grade as well as with benign behavior.

Spatial Inhibition of Return Affected by Self-Prioritization Effect in Three-Dimensional Space
Authors: Liu Xiaoyuan , Qian Qinyue , Wang Lingyun , Wang Aijun , Zhang Ming
Published: February 2021

Spatial inhibition of return (IOR) being affected by the self-prioritization effect (SPE) in a two-dimensional plane has been well documented. However, it remains unknown how the spatial IOR interacts with the SPE in three-dimensional (3D) space. By constructing a virtual 3D environment, Posner’s classically two-dimensional cue-target paradigm was applied to a 3D space. Participants first associated labels for themselves, their best friends, and strangers with geometric shapes in a shape-label matching task, then performed Experiment 1 (referential information appeared as the cue label) and Experiment 2 (referential information appeared as the target label) to investigate whether the IOR effect could be influenced by the SPE in 3D space. This study showed that when the cue was temporarily established with a self-referential shape and appeared in far space, the IOR effect was the smallest. When the target was temporarily established with a self-referential shape and appeared in near space, the IOR effect disappeared. This study suggests that the IOR effect was affected by the SPE when attention was oriented or reoriented in 3D space and that the IOR effect disappeared or decreased when affected by the SPE in 3D space.
Immigrants, Crime, and the American Dream: Testing a Segmented Assimilation Theory of Crime
Authors: McCann Wesley S. , Zhang Saijun , Boateng Francis D.
Published: February 2021

The immigrant-crime relationship is often misunderstood and highly complex. To date, criminological research has largely ignored theory testing of this relationship. This paper examines the extant literature on intergenerational offending amongst immigrant youth and subsequently tests whether the segmented assimilation theory- a theory borrowed from the interdisciplinary social sciences- adequately explains immigrant offending. The study uses data ( N = 1,267) from the Pathways to Desistance Study (PTD) to examine intergenerational differences in changes to offending between immigrant youth and the native-born. The analyses largely reveal that the theory, based on its original assumptions, fails to adequately explain youth offending, and that the models provide more support for the straight-line theory of assimilation in regards to delinquency. Limitations and recommendations are discussed and proffered, respectively.
Views about sensory modulation from people with schizophrenia and treating staff: A multisite qualitative study
Authors: Machingura Tawanda , Lloyd Chris , Murphy Karen , Goulder Sarah , Shum David , Green and Heather
Published: February 2021

Introduction

Current non-pharmacological treatment options for people with schizophrenia are limited. There is, however, emerging evidence that sensory modulation can be beneficial for this population. This study aimed to gain insight into sensory modulation from the user’s and the treating staff’s perspectives.

Method

A qualitative content analysis design was used. Transcripts from occupational therapists ( n=11) and patients with schizophrenia ( n=13) derived from in-depth semi-structured interviews were analysed for themes using content analysis.

Results

Five themes emerged from this study: Service user education on the sensory approach is the key; A variety of tools should be tried; Sensory modulation provides a valued treatment option; There are challenges of managing perceived risk at an organisational level; and There is a shortage of accessible and effective training.

Conclusion

People with schizophrenia and treating staff had congruent perceptions regarding the use of sensory modulation as a treatment option. The findings suggest that sensory modulation can be a valued addition to treatment options for people with schizophrenia. We suggest further research on sensory modulation intervention effectiveness using quantitative methods so these results can be further explored.
Beyond death and taxes: Fiscal studies and the fiscal state
Authors: Whiteside Heather
Published: February 2021

The past decade has seen a resurgence of interdisciplinary interest in fiscal studies, from the new fiscal sociology to fiscal geographies and beyond, with roots in the 20th century theories of Schumpeter (liberal) and O’Connor (Marxian). The notion of a ‘tax state’ remains particularly germane, and indeed fiscal studies have all but narrowed to assessments of the relations and implications of taxation. This paper calls for a meaningful engagement with the ‘fiscal’ in fiscal studies where taxation is better understood as being but one component of public sector revenue and expenditure (alongside other important features like asset ownership, debt/credit, and intergovernmental transfers). More than an academic quibble over terminology or unit of analysis, narrowing ‘fiscal’ to ‘tax’ obscures many budget items and misses out on important temporal trends in the political economy of state revenue and expenditure. These issues are explored in two parts: the roots of fiscal studies (politicizing theoretical underpinnings), and the various conjunctural features of the fiscal state (tracing the temporal through Canadian examples).
Contrasting Perspectives on the Comfort and Safety of Pedestrians Interacting with Other Road Users
Authors: Bigazzi Alexander , Gill Gurdiljot , Winters Meghan
Published: February 2021

Assessments of interactions between road users are crucial to understanding comfort and safety. However, observers may vary in their perceptions and ratings of road user interactions. The objective of this paper is to examine how perceptions of yielding, comfort, and safety for pedestrian interactions vary among observers, ranging from members of the public to road safety experts. Video clips of pedestrian interactions with motor vehicles and bicycles were collected from 11 crosswalks and shown to three groups of participants (traffic safety experts, an engaged citizen advisory group, and members of the general public) along with questions about yielding, comfort, and risk of injury. Experts had similar views of yielding and comfort to the other two groups, but a consistently lower assessment of injury risk for pedestrians in the study. Respondent socio-demographics did not relate to perceptions of yielding, comfort, or risk, but self-reported travel habits did. Respondents who reported walking more frequently rated pedestrian comfort as lower, and respondents who reported cycling more frequently rated risk as lower for pedestrian interactions with both motor vehicles and bicycles. Findings suggest small groups of engaged citizens can provide useful information about public perspectives on safety that likely diverge from expert assessments of risk, and that sample representation should be assessed in relation to travel habits rather than socio-demographics.

Objectives:

To analyze the feasibility, safety and advantages of Laparo-Endoscopic Single-site Surgery radical prostatectomy (LESS-RP) based on our personal experience.

Patients and methods:

Details of 520 patients were retrospectively analyzed, from 2009 to 2019. Extraperitoneal approach, with only two accesses (2.5 cm and 5 mm respectively) was used to perform radical prostatectomy. Perioperative characteristics and postoperative oncologic and functional outcomes are reported.

Results:

The mean age was 66.6 ± 5.6 years. Mean PSA level was 9 ± 3.5 ng/ml. According to D’Amico classification, the percentage of patients with low-, intermediate-, and high-risk disease cases were 116 (22.4%), 275 (52.8%), and 129 (24.8%) respectively. Mean operative time was 156 ± 43 min. Mean estimated blood loss was 214 ± 93 ml. Positive surgical margins (PSMs) were detected in 110 (21.2%) patients. PSM rates in pT2 and pT3 stages were 20.1% and 22.9%, respectively. The overall complication rate was 9.2%, based on the modified Clavien classification. The 12 months continence and potency rates were 90.9% and 49.1%, respectively. The biochemical recurrence rate was 6.8%, at the median follow-up time of 26.7 months (IQR 12–32).

Conclusions:

Our analyses show that LESS-RP is a safe procedure, if performed by surgeons with adequate experience and skills. Unlike the classic laparoscopic prostatectomy, this technique allows better aesthetic and psychological results, reduced postoperative pain, and a faster return to normal daily activity with the same functional and oncological results.
Do low dose CT-KUBs really expose patients to more radiation than plain abdominal radiographs?
Authors: Yang Bob , Suhail Noorunisa , Marais Johan , Brewin James
Published: February 2021

Background:

Urolithiasis patients often require frequent urinary tract imaging, leading to high radiation exposure. CT Kidney-Ureter-Bladder (CT-KUB) is the gold standard in urolithiasis detection, however it is thought to harbour significant radiation load. Urologists have therefore utilised abdominal radiographs (XR-KUB) as an alternative, though with markedly lower sensitivity and specificity. We present the first contemporary UK study comparing the effective doses of XR-KUBs with low dose CT-KUBs.

Method:

Fifty-three patients were retrospectively identified in a single centre who underwent both a XR-KUB and a CT-KUB in 2018. Effective-Dose was measured by converting the recorded ‘Dose Area/Length Product’ via the International Commission on Radiological Protection formula.

Results:

The average effective dose of XR-KUBs and low dose CT-KUBs were 5.10 mSv and 5.31 mSv respectively. Thirty-four percent (18/53) of patients had a XR-KUBs with a higher effective dose than their low dose CT-KUB. Patients with higher Weight, BMI and AP diameter had higher effective doses for both their XR and low dose CT-KUBs. All patients in our study weighing over 92 kg or with a BMI greater than 32 had a XR-KUBs with a higher effective dose than their low dose CT-KUB.

Conclusion:

This data supports moving away from XR-KUBs for the investigation of urolithiasis, particularly in patients with a high BMI.
The psychodynamics of lynch mobs: Grouping, ganging or lynching
Authors: Stevenson Stuart
Published: February 2021

This article engages with human groupings when they are operating at their very worst. These are human groupings enacting a particularly insidious, enduring and specific set of ‘othering’ dynamics that occur within and between in-groups and out-groups. This is known as lynching and these vicious and destructive human groupings are known as ‘lynch mobs’. I attempt to bring a psychodynamic lens to explore the complex issues that constitute the particular group dynamics enacted by ‘lynch mobs’ that usually target members of marginalized communities. I consider the meaning of the assault in the context of white supremacy and, whilst foregrounding race in the discussion, recognizing that members of other marginalized groups such as gay men and women are often lynched. The article shows how psychodynamic ideas can contribute to our understanding of this most horrific and inhumane phenomena, and can provide clinicians with some conceptual tools to manage the myriad of complex issues related to lynching and how it presents currently. Can lynching dynamics be compared and contrasted with bullying and scapegoating dynamics and, if so, can they be paralleled and operate more subtly and interpersonally in our psychotherapy groups and within our organizations and work teams? If so, do we have the theoretical and conceptual skills to work with them? I argue that there is now more than ever a need to remain relevant to the diverse and often-marginalized communities we serve and that we must develop our theories and practices to address such phenomena. To do this requires group analysts and, indeed, all clinicians to urgently scrutinize and develop theories and techniques in working with these very dangerous othering dynamics in our practices and clinics. A lack of intervention equates to by-standing or turning a blind eye, which is a significant factor in lynching dynamics, and a complicit collusion with the traumatization of marginalized communities.
Atteintes Neurodéveloppementales, Comorbidités Psychiatriques Et Pathologies Associées Chez Des Patients Atteints de Schizophrénie Très Précoce Avec Symptômes Autistiques Prémorbides.
Authors: Fernandez A , Pasquet-Levy M , Laure G , Thümmler S , Askenazy F
Published: February 2021

Introduction:

La schizophrénie très précoce (STP) est une forme rare (1/40000), grave et neurodéveloppementale de schizophrénie débutant avant 13 ans. Les comorbidités et atteintes associées spécifiques des STP étant peu étudiées, l’objectif de notre étude a été de les évaluer sur le plan psychiatrique, neurodéveloppemental et somatique.

Méthode:

Il s’agit d’une étude ancillaire du protocole GenAuDiss. Un entretien psychiatrique standardisé (K-SADS-PL DSM5) et un bilan neuropsychologique (WISC-V/WAIS-IV) ont été effectués chez les patients atteints de STP ainsi qu’une anamnèse concernant la grossesse, la périnatalité, le développement, la biographie et les antécédents médicaux et psychiatriques, personnels et familiaux.

Résultats:

20 sujets ont été inclus. L’âge moyen de début du trouble était de 8,90 ans (+/−2,30). Les comorbidités psychiatriques (DSM5) étaient le Trouble Déficitaire de l’Attention avec Hyperactivité (15/20 patients), les troubles anxieux (14/20) et le Trouble du Spectre de l’Autisme (13/20). Le QI moyen était de 70,26 (+/−18,09). Un retard de langage et une rupture de parcours scolaire étaient notés chez 18/20 patients. Enfin, l’affection somatique principale associée était l’asthme (15/20 patients).

Discussion:

Nous avons mis en évidence chez nos patients atteints de STP une fréquence élevée de comorbidités dont au moins un trouble psychiatrique systématique. Or, bien que la schizophrénie infantile soit une pathologie de pronostic sévère impactant le patient, sa famille et la société, sa prise en charge demeure essentiellement symptomatique. En pratique clinique, il apparaît nécessaire de rechercher systématiquement ces comorbidités et de les prendre en charge pour améliorer la qualité globale des soins.
Education and Social Trust in Global Perspective
Authors: Wu Cary
Published: February 2021

A large literature has suggested that education leads to higher trust. In this article, I argue that how education and trust are associated at the individual level may depend on the level of risk and uncertainty of each institutional setting. Trust involves not only individuals’ risk-taking propensity and capability but also their perception of how uncertain or risky the situation they are in. I test this micro–macro interactive approach by analyzing data from the World Values Survey, the European Social Survey, and the World Bank. Results show that the education and trust association can change from positive to negative both cross-nationally and within national contexts over time in response to the social and political stability at the macro level. In stable and low-conflict societies, the association between education and trust is highly positive. However, the association becomes negative in transitional societies where social and political risks are widespread. Supporting the risk-taking and risk awareness mechanisms underpinning the interactive process, I show that education has varying impacts on risk-taking propensity and risk awareness across different institutional contexts.

Objectives:

To analyze prefrailty’s relationship with limitations in activities of daily living (ADLs) and restrictions in social participation.

Method:

Robust (Fried 0/4; n = 214; Mage = 82.3 years [ SD ±2.1]) and prefrail (Fried 1–2/4; n = 191; Mage = 83.8 years [ SD ±3.2]) community-dwelling older individuals were included. Frailty scores were obtained from weight loss, exhaustion, gait speed, and grip strength. A total disability index (DI) expressed dependency for basic (b-), instrumental (i-), and advanced (a-)ADLs. Total participation score, being a member, total number of memberships, being a board member, level of participation, membership over time, volunteering, and formal participation represented social participation.

Results:

Logistic regression retained age (OR = 1.224; 95% CI = [1.122, 1.335]), sex (OR = 3.818; 95% CI = [2.437, 5.982]), and a-ADL-DI (OR = 1.230; 95% CI = [1.018, 1.486]) as variables significantly related to prefrailty (68.3%; χ2 = 68.25; df = 3; p < .001).

Discussion:

Subtle limitations in a-ADLs, higher age, and being a man were associated with prefrailty, revealing the possible role of personal and culturally related a-ADLs as red flags for (pre)frailty.
