Individual Target Problems, Self-Observation and Change in Short-Term Psychodynamic Psychotherapy
Authors: Savolainen Juha , Lindfors Olavi , Leiman Mikael
Published: August 2023

The objective of this study was to analyze and illustrate the relationships between different expectations for psychotherapy, quality of self-observation and change in short-term psychodynamic psychotherapy. To conduct this, two patients from the Helsinki Psychotherapy Study were selected for qualitative analysis. The selection was based on the patients’ responses on the Target Complaints (TC) questionnaire, i.e., reasons for seeking psychotherapy, completed as part of the pre-treatment patient assessment. TC responses were classified as psychiatric symptoms or personality and functioning problems. The data for further analysis was selected for both patients from pre-treatment interviews and two follow-up interviews and analyzed in detail by dialogical sequence analysis (DSA), considering the quality of self-observation as a factor contributing to change. As a result, qualitative changes in relation to problematic experiences and development of self-observation appeared in the patient with mainly personality and functioning problems. In contrast, there were little respective changes in the experience of the patient whose target problems were limited to psychiatric symptoms. The results suggest that a patient’s exclusive identification of psychiatric symptoms as target problems may indicate poor suitability for short-term psychodynamic psychotherapy which emphasizes the developmental nature of psychotherapeutic change and the importance of self-observation as a factor of change.
Flammability analysis of poly(ethylene terephthalate) and recycled PET with pyrolyzed filler
Authors: Majka Tomasz M.
Published: August 2023

The future is the recovery of the filler and its reuse in hybrid materials. It is important that as a result of recycling, the filler does not lose its properties, but acquires new ones. The aim of this research work was to investigate the effect of filler recovered by pyrolysis on the flammability of poly(ethylene terephthalate) and recycled PET. It was important to obtain a flammability class higher or equal to the pure PET and RPET matrix. Flammability tests carried out using the UL94, LOI, and PCFC methods allowed perform a first characterization of the properties of materials during their combustion. These studies show that it becomes possible to give specific functional properties to recycled fillers.

Published: August 2023

Fungal specimens parasitic on spider egg sacs (Araneidae sensu lato) were collected, isolated, and identified based on molecular phylogenetic analyses of five nuclear loci (ITS, LSU, TEF1, RPB1 and RPB2) combined with morphological data. In this study, one novel monotypic genus is described, Bhushaniella rubra for Thailand. Bhushaniella rubra is characterized by producing superficial perithecia. Its anamorph has a unique character by producing verticillate phialides with a slightly curved neck. A concurrent evaluation of the secondary metabolites of the mycelial extracts of the new fungus revealed the presence of picoline alkaloids of the penicolinate type, for which we propose the trivial names penicolinates F and G. Their chemical structures were elucidated by two-dimensional nuclear magnetic resonance (2D-NMR) spectroscopy and high resolution mass spectrometry (HR-MS). They only showed weak to no antibiotic activity and were devoid of significant cytotoxic effects.
Leading-by-example: a meta-analysis
Authors: Eisenkopf Gerald , Kölpin Torben
Published: August 2023

We provide a parsimonious model of leadership in social dilemma situations and test it with a meta-analysis of experimental studies. We focus on studies with treatments that allow for sequential contributions to a public good [as in Güth et al. (J Public Econ 91:1023–1042, 2007)]. The group members observe the contribution of a leader before contributing themselves. We compare the results with simultaneous contribution treatments from the same studies. Our results confirm that the establishment of a leader indeed leads to persistently higher and more coordinated contributions. As predicted, the aggregate effect remains stable over time and increases in group size even though leaders and followers have more divergent contribution patterns in larger groups. We also find empirical support for an explanation of the observed ‘leader’s curse’.
Problematizing Modern Democracy in the United States:
Authors: Simon Julia
Published: August 2023

Since Donald Trump’s presidency and the diverse efforts to undermine the transfer of power after the 2020 election, the risks of extreme polarization and democratic backsliding in the United States (US) have been highlighted in the literature. Yet the epistemic dimension of these developments remains underresearched. Embedded in a genealogical Foucauldian governmentality/counter-conduct approach, this contribution addresses the puzzle of how election denialism and related (violent) anti-system activity are being rationalized, legitimized, and anchored in political subjectivities as efforts to ‘protect’ American democracy. This perspective allows to inquire into liberalism’s authoritarian potential that can be mobilized through different forms of counter-conduct. The study analytically disentangles these forms based on their prime targets, modes of operation, and the forms of knowledge they rely on. Focusing on the swing state of Arizona, the empirical analysis furthermore highlights the role of the subnational level in interlinking counter-conduct and (autocratizing) governmental practices in a federal system. Conceptually, the study renders visible a profound struggle over the epistemic foundations of the current liberal constitutional and political order that clearly transcends the issue of the 2020 election, Donald Trump, and even the context of the United States. Indeed, similar patterns of subjectivation and counter-conduct can also be detected for example in Germany. Moreover, this paper expands the scope of the concept of counter-conduct to study radical right-wing contestations and related questions of epistemic (in)justice. It thereby seeks to encourage debate on how political science can address the pluralization and polarization of contents, standards, and forms of knowledge as they become relevant to democratic backsliding.

Published: August 2023

Smallholder farmers and their agroecosystems in active volcanic landscapes need to deal with and recover from eruptions. Resilience to extreme shocks may increase with system diversity, enhancing food and income security and ecosystem services provision; however, the longer term effects of volcanic ash are rarely assessed. To test the hypothesis that tree diversity contributes to the social–ecological resilience of coffee-based agroforestry, we quantified (1) the immediate effects of deposition of a 15-cm ash layer on tree survival, (2) the effect of volcanic ash on aboveground C stocks, tree diversity and wood density frequencies, (3) litter layer dynamics, and (4) farming system and income recovery 3 years after. Observations in four land-use systems before and after ash deposition (remnant forest, coffee-based complex and simple agroforestry, annual crops) were complemented by 46 farmer interviews on tree species’ survival, system, and financial recovery. Based on farmer interviews, low-wood-density trees were most affected by volcanic ash deposition. Ash deposition did not, after 3 years and across land-use systems, significantly change tree density, basal area, or C stocks. In contrast, species richness in coffee-based agroforestry increased significantly. Standing litter stocks in agroforestry decreased, but slower decomposition partially compensated for reduced litter input. Farmers stated that diversity and flexibility in coffee-based agroforestry support a system recovery that is faster than that for annual crops, suppressing income fluctuation. Farmer’s adaptive responses to enhance species diversity contributed to the resilience of farms, by retaining basic system structure and functions of agroforestry, and increasing product diversity and income.

Shape-based functional data analysis
Authors: Wu Yuexuan , Huang Chao , Srivastava Anuj
Published: August 2023

Functional data analysis (FDA) is a fast-growing area of research and development in statistics. While most FDA literature imposes the classical$$\mathbb {L}^2$$L2Hilbert structure on function spaces, there is an emergent need for a different, shape-based approach for analyzing functional data. This paper reviews and develops fundamental geometrical concepts that help connect traditionally diverse fields of shape and functional analyses. It showcases that focusing on shapes is often more appropriate when structural features (number of peaks and valleys and their heights) carry salient information in data. It recaps recent mathematical representations and associated procedures for comparing, summarizing, and testing the shapes of functions. Specifically, it discusses three tasks: shape fitting, shape fPCA, and shape regression models. The latter refers to the models that separate the shapes of functions from their phases and use them individually in regression analysis. The ensuing results provide better interpretations and tend to preserve geometric structures. The paper also discusses an extension where the functions are not real-valued but manifold-valued. The article presents several examples of this shape-centric functional data analysis using simulated and real data.

Osteoarthritis (OA) is the most common form of arthritis, that causes a significant decrease in the quality of life of the afflicted and constitutes a great burden for the socioeconomic system. Trace elements and heavy metals are implicated in the pathophysiology of OA, exacerbating inflammatory and oxidative stress responses. The aim of this cross-sectional study was to quantify metals in plasma samples of Greek OA patients and explore their link with disease related parameters, health status or quality of life, as well as epigenetic OA markers. This is the first study on plasma metal levels in Greek knee OA patients. To achieve precision in plasma metal and miRNA measurements, high-quality samples were selected from a subset of 34 participants (NCT04783792). Demographic, quality of life, clinical, biochemical, inflammation, oxidative stress, and anthropometric parameters, as well as microRNA levels were assessed. Significant correlations were found between circulating metals with OA related parameters or with measured microRNAs. Also, significant positive associations between plasma copper (Cu) levels and CRP (p = 0.033) or IL-6 (p = 0.001) occurred when adjusting for age, gender, BMI, physical activity level, smoking, disease severity, total arthroplasty, and dietary intake of the respective metal. Cu’s role in OA is bidirectional, and this study confirms the findings that in OA, Cu is positively associated with inflammation. Such relationships between lifestyle, environment and OA enhance our understanding and encourage further study on metals related to OA inflammation.
Spreading of Tau Protein Does Not Depend on Aggregation Propensity

Published: August 2023

The stereotypical progression of Tau pathology during Alzheimer disease has been attributed to trans-neuronal spreading of misfolded Tau proteins, followed by prion-like templated aggregation of Tau. The nature of Tau and the cellular mechanisms of Tau spreading are still under debate. We hypothesized that Tau’s propensity for aggregation would correlate with its ability to spread across synapses and propagate pathology. To study the progressive propagation of Tau proteins in brain regions relevant for Alzheimer disease, we used mice expressing near-physiological levels of full-length human Tau protein carrying pro-aggregant (TauΔK280, TauΔK) or anti-aggregant (TauΔK280-PP, TauΔK−PP) mutations in the entorhinal cortex (EC). To enhance Tau expression in the EC, we performed EC injections of adeno-associated virus (AAV) particles encoding TauΔK or TauΔK−PP. The brains of injected and non-injected EC/TauΔK and EC/TauΔK−PP mice were studied by immunohistological and biochemical techniques to detect Tau propagation to dentate gyrus (DG) neurons and Tau-induced pathological changes. Pro- and anti-aggregant mice had comparable low transgene expression (~0.2 times endogenous mouse Tau). They accumulated human Tau at similar rates and only in expressing EC neurons, including their axonal projections of the perforant path and presynaptic terminals in the molecular layer of the DG. Pro-aggregant EC/TauΔK mice showed misfolded Tau and synaptic protein alterations in EC neurons, not observed in anti-aggregant EC/TauΔK−PP mice. Additional AAV-mediated expression of TauΔK or TauΔK−PP in EC/TauΔK or EC/TauΔK−PP mice, respectively, increased the human Tau expression to ~0.65 times endogenous mouse Tau, with comparable spreading of TauΔK and TauΔK−PP throughout the EC. There was a low level of transcellular propagation of Tau protein, without pathological phosphorylation or misfolding, as judged by diagnostic antibodies. Additionally, TauΔK but not TauΔK−PP expression induced hippocampal astrogliosis. Low levels of pro- or anti-aggregant full-length Tau show equivalent distributions in EC neurons, independent of their aggregation propensity. Increasing the expression via AAV induce local Tau misfolding in the EC neurons, synaptotoxicity, and astrogliosis and lead to a low level of detectable trans-neuronal spreading of Tau. This depends on its concentration in the EC, but, contrary to expectations, does not depend on Tau’s aggregation propensity/misfolding and does not lead to templated misfolding in recipient neurons.
Role of Brain Liver X Receptor in Parkinson’s Disease: Hidden Treasure and Emerging Opportunities

Published: August 2023

Parkinson’s disease (PD) is a neurodegenerative disease due to the degeneration of dopaminergic neurons (DNs) in the substantia nigra (SN). The liver X receptor (LXR) is involved in different neurodegenerative diseases. Therefore, the objective of the present review was to clarify the possible role of LXR in PD neuropathology. LXRs are the most common nuclear receptors of transcription factors that regulate cholesterol metabolism and have pleiotropic effects, including anti-inflammatory effects and reducing intracellular cholesterol accumulation. LXRs are highly expressed in the adult brain and act as endogenous sensors for intracellular cholesterol. LXRs have neuroprotective effects against the development of neuroinflammation in different neurodegenerative diseases by inhibiting the expression of pro-inflammatory cytokines. LXRs play an essential role in mitigating PD neuropathology by reducing the expression of inflammatory signaling pathways, neuroinflammation, oxidative stress, mitochondrial dysfunction, and enhancement of BDNF signaling.

In conclusion, LXRs, through regulating brain cholesterol homeostasis, may be effectual in PD. Also, inhibition of node-like receptor pyrin 3 (NLRP3) inflammasome and nuclear factor kappa B (NF-κB) by LXRs could effectively prevent neuroinflammation in PD. Taken together, LXRs play a crucial role in PD neuropathology by inhibiting neuroinflammation and associated degeneration of DNs.
A stochastic policy algorithm for seasonal hydropower planning
Authors: Grini Håkon S. , Danielsen Anders S. , Fleten Stein-Erik , Kleiven Andreas
Published: August 2023

Hydropower producers need to plan several months or years ahead to estimate the opportunity value of water stored in their reservoirs. The resulting large-scale optimization problem is computationally intensive, and model simplifications are often needed to allow for efficient solving. Alternatively, one can look for near-optimal policies using heuristics that can tackle non-convexities in the production function and a wide range of modelling approaches for the price- and inflow dynamics. We undertake an extensive numerical comparison between the state-of-the-art algorithm stochastic dual dynamic programming (SDDP) and rolling forecast-based algorithms, including a novel algorithm that we develop in this paper. We name it Scenario-based Two-stage ReOptimization abbreviated as STRO. The numerical experiments are based on convex stochastic dynamic programs with discretized exogenous state space, which makes the SDDP algorithm applicable for comparisons. We demonstrate that our algorithm can handle inflow risk better than traditional forecast-based algorithms, by reducing the optimality gap from 2.5 to 1.3% compared to the SDDP bound.

Introduction

Candida tropicalis is a common non-albicans Candida (NAC) species that causes numerous fungal infections. Increasing antifungal resistance to azoles in NAC is becoming a major health problem worldwide; however, in Egypt, almost no data is available regarding fluconazole resistance mechanisms in C. tropicalis. The current study aims to investigate two possible important molecular mechanisms involved in fluconazole resistance in C. tropicalis isolates.

Materials

Fifty-four clinical C. tropicalis isolates were included. Identification and antifungal susceptibility profiles of the isolates were carried out using the VITEK 2 compact system. The molecular investigation of fluconazole resistance included the expression of the CDR1 and MDR1 genes by quantitative real-time RT-PCR as well as the sequence analysis of the ERG11 gene.

Results

Antifungal susceptibility testing identified 30 fluconazole-non-susceptible isolates. Statistically, CDR1 gene expression in fluconazole-non-susceptible isolates was significantly higher than that in fluconazole-susceptible isolates, with MDR1 gene expression levels that were similar in both non-susceptible and susceptible isolates. Sequence analysis of the ERG11 gene of 26 fluconazole-resistant isolates identified two missense mutations: A395T (Y132F) and G1390A (G464S).

Conclusions

This study has highlighted the role of overexpression of the CDR1 gene and ERG11 gene mutations in fluconazole non-susceptibility. Further studies in Egypt are required to investigate other possible molecular mechanisms involved in azole resistance.

Effects of blowing upon dynamic stability of blunt nosed re entry vehicles pitching in hypersonic flow
Authors: Khalid M. , Juhany K.A.
Published: August 2023

Blowing is often used to alleviate the intense heating rates on blunt noses of hypersonic vehicles. This flow efflux at the leading edge transforms the flow field in the blunt-nose regions with implications on the dynamic stability of the vehicles. As a demonstrative exercise, the flow fields past blunt-nosed and truncated-nosed conical bodies under blowing and no-blowing conditions were perturbed to obtain the unsteady effects using the shock expansion method to recover the unsteady pressure coefficient. Static and pitching moment derivatives were then duly obtained by integrating the differential of the unsteady pressure coefficient with respect to the pitch angle (α) or the pitch rate (
$\dot \theta $
) together with the moment arm with reference to the centre of gravity. The results obtained for blunt-nose and truncated conical bodies show a noticeable drop in dynamic stability. Even when the flow is transformed from a tangential blowing at the shoulder of the blunt-nosed vehicle shows some degradation in dynamic stability.
Canadian Healthcare Access in Parkinson’s Disease and COVID-19: A Cross-Sectional Survey
Authors: McKeown Monica D. , Crighton Eric , Mestre Tiago A. ,   iCARE-PD consortium
Published: August 2023

Background:

Parkinson’s disease (PD) is a common chronic neurodegenerative condition. As a result of the COVID-19 pandemic, healthcare provision faced challenges worldwide. We aimed to explore how the COVID-19 pandemic changed healthcare experiences for people living with Parkinson’s disease (PwP) in Canada.

Methods:

We conducted a national cross-sectional online survey about healthcare access for PwP in 2020. Participants (n = 298) were recruited through Parkinson Canada, the national patient association and its provincial partners, that advertised the study in a monthly newsletter. We used descriptive statistics and multivariate regression modelling to test associations of interest. A P < 0.05 was deemed statistically significant.

Results:

During the COVID-19 pandemic, PwP reported greater difficulty obtaining PD-related healthcare services and lesser satisfaction with healthcare provision compared to pre-pandemic experiences. Dissatisfaction with care was associated with the presence of barriers to access services, a lack of confidence in accessing services remotely, pre-pandemic care dissatisfaction, and difficulty in obtaining care during the COVID-19 pandemic. Unmet care needs were associated with a lack of confidence in accessing services remotely, dissatisfaction with pre-pandemic care, difficulty obtaining pre-pandemic care, and communication challenges.

Conclusion:

Our results suggest that healthcare experiences for PwP significantly changed during the COVID-19 pandemic, with challenges in access to virtual care. Poorer pre-pandemic care experiences were amplified during the pandemic.
Disjoint hypercyclicity, Sidon sets and weakly mixing operators
Authors: CARDECCIA RODRIGO
Published: August 2023

We prove that a finite set of natural numbers J satisfies that
$J\cup \{0\}$
is not Sidon if and only if for any operator T, the disjoint hypercyclicity of
$\{T^j:j\in J\}$
implies that T is weakly mixing. As an application we show the existence of a non-weakly mixing operator T such that
$T\oplus T^2\oplus\cdots \oplus T^n$
is hypercyclic for every n.
Spike formation theory in three-dimensional flow separation

Published: August 2023

We develop a frame-invariant theory of material spike formation during flow separation over a no-slip boundary in three-dimensional flows with arbitrary time dependence. Based on the exact evolution of the largest principal curvature on near-wall material surfaces, our theory identifies fixed and moving separation. Our approach is effective over short time intervals and admits an instantaneous limit. As a byproduct, we derive explicit formulas for the evolution of the Weingarten map and the principal curvatures of any surface advected by general three-dimensional flows. The material backbone we identify acts first as a precursor and later as the centrepiece of Lagrangian flow separation. We discover previously undetected spiking points and curves where the separation backbones connect to the boundary and provide wall-based analytical formulas for their locations. We illustrate our results on several steady and unsteady flows.
Flows in fluid-walled conduits driven by Laplace pressure
Authors: Nebuloni Federico , Cook Peter R. , Walsh Edmond J.
Published: August 2023

In conventional microfluidic devices, fluids are often confined behind solid plastic walls that restrict access and trap gas bubbles; in open microfluidics some solid walls are replaced by fluid ones (i.e. interfaces with immiscible fluids). In both cases, flows are usually driven by external pumps or gravity. An innovative open technology has been developed in which two-dimensional patterns of cell-culture medium in standard Petri dishes are confined by fluid walls made of an immiscible and bio-inert fluorocarbon (FC40). To provide refreshing media flows to cells in such circuits, an established pumping system that exploits differences in Laplace pressure across open interfaces has been applied to drive flow without using external pumps: a source drop autonomously empties through a straight conduit into the rest of the dish (the sink). Whereas conduits with solid walls have unchanging boundaries and flows within them are well understood, the challenge is to predict flows in circuits where fluid walls morph as pressures change. Numerical and semi-analytical equations enabling the prediction of changing flows are developed, and predictions validated experimentally.
Snap-through dynamics of a buckled flexible filament in a uniform flow
Authors: Mao Qian , Liu Yingzheng , Sung Hyung Jin
Published: August 2023

The flow-induced snap-through dynamics of a buckled flexible filament was explored using the penalty immersed boundary method. The effects of the filament length, bending rigidity and Reynolds number on the mode transition were systematically examined. Three different modes were observed when the aforementioned parameters were varied: an equilibrium mode, a streamwise oscillation mode and a snap-through oscillation mode. Two mode transitions occurred when the bending rigidity was lowered and the length and Reynolds number were increased: a direct transition from the equilibrium mode to the snap-through oscillation mode and the successive appearance of the three modes. An increase in transverse fluid force induced the snap-through oscillation mode. A vortex-induced vibration and a self-excited vibration occurred in the streamwise oscillation mode and the snap-through oscillation mode, respectively. A wake pattern of 2S appeared in the streamwise oscillation mode, and a pattern of 2S + 2P appeared in the snap-through oscillation mode. A hysteresis was observed near the critical Reynolds number. The hysteresis loop increased in magnitude with increasing bending rigidity. The greater energy harvesting was achieved by the larger deflection and the higher strain energy. We found that most of the strain energy was concentrated in the last half of the filament.
The Paradox of Justice: From Transitional to Everyday Justice
Authors: Dixon Peter , Firchow Pamina , Vera-Adrianzén Fiorella
Published: August 2023

Transitional justice lacks a coherent framework for articulating the relationship between distributive and corrective justice. Academic debates remain largely normative, focused on whether and how transitional justice should distinguish itself from the realm of the social, economic, and cultural. Where there is a bridge between legal logics and lived realities, it generally happens through victims’ consultation, but these are often thinly designed processes, revolving around questions like “what do victims want” or failing to turn expectations into action. Taking inspiration from Sally Engle Merry’s “paradox of measurement,” in which measurements produce the realities they assess, we pose a “paradox of justice” in which victims’ lived experiences are filtered and reproduced through the technology of consultation. While important, the question of “what do victims want” ultimately oversimplifies the complexities of how injustice is experienced. Drawing on a unique dataset of everyday indicators of justice from Colombia, this article establishes a framework for articulating the experiential dimensions of post-conflict justice. Ultimately, this framework highlights that justice is a process—whether in the courtroom or in a village reckoning with a massacre—and that the kinds of relationships that justice institutions build with victims are of equal relevance to what these institutions ultimately deliver.
Drinking Tea with the Neighbors: Informal Clubs, General Trust, and Trustworthiness in Mali

Published: August 2023

There has been scant empirical evidence linking associational membership to general trust and trustworthiness. This study explores urban youth clubs in Mali and asks: is membership in these groups associated with greater trust and trustworthiness toward society? It leverages 18 months of fieldwork, including 375 group surveys, 2,525 individual surveys, over 1,300 trust games, and transcripts from 66 focus groups. We use propensity score matching to analyze how members and nonmembers play the trust game with strangers. Members are more trustworthy; they return 12% more to their partners than nonmember peers. We do not find a systematic effect of membership on trust. Trustworthiness in the game is also positively correlated with self-reported trust and tolerance as well as real-world behaviors including volunteering and helping friends. Focus group data highlight five mechanisms by which membership fosters general trustworthiness: bonding among diverse members, bridging, public goods provision, socialization, and psychological support.
The spectral eigenmatrix problems of planar self-affine measures with four digits

Published: August 2023

Given a Borel probability measure µ on $\mathbb{R}^n$ and a real matrix $R\in M_n(\mathbb{R})$. We call R a spectral eigenmatrix of the measure µ if there exists a countable set $\Lambda\subset \mathbb{R}^n$ such that the sets $E_\Lambda=\big\{{\rm e}^{2\pi i \langle\lambda,x\rangle}:\lambda\in \Lambda\big\}$ and $E_{R\Lambda}=\big\{{\rm e}^{2\pi i \langle R\lambda,x\rangle}:\lambda\in \Lambda\big\}$ are both orthonormal bases for the Hilbert space $L^2(\mu)$. In this paper, we study the structure of spectral eigenmatrix of the planar self-affine measure $\mu_{M,D}$ generated by an expanding integer matrix $M\in M_2(2\mathbb{Z})$ and the four-elements digit set $D = \{(0,0)^t,(1,0)^t,(0,1)^t,(-1,-1)^t\}$. Some sufficient and/or necessary conditions for R to be a spectral eigenmatrix of $\mu_{M,D}$ are given.
‘The nation has conquered the state’: Arendtian insights on the internal contradictions of the nation-state
Authors: Verovšek Peter J.
Published: August 2023

The globalisation of political power into structures ‘above’ or ‘beyond’ the nation-state has increasingly been called into question as part of a ‘sovereigntist turn’ in contemporary politics. While such demands for local control by bounded peoples may be democratic, empirically they often also take a nationalist form. Building on Hannah Arendt’s analysis of how ‘the nation conquered the state’, I argue that the slippage from democratic to national sovereigntism is rooted in fundamental conceptual instabilities within the concept of the nation-state. Whereas the first term in this hyphenated construct favours certain individuals based on their ethnic background, the latter is a universal concept that demands the equal treatment of all. My basic thesis is that these internal contradictions help to explain the nationalist tendency in calls to return political power to the nation-state. I illustrate these points by drawing on examples from the ‘illiberal democracies’ of Central-Eastern Europe, focusing on Poland and Hungary.
On the effectiveness of public awareness campaigns for the management of invasive species

Published: August 2023

Invasive species can have disastrous effects on the ecosystems they invade, requiring costly, labour-intensive mitigation. Public awareness campaigns are often used as a tool to reduce these species’ impacts. While heralded as useful and cost-effective, little evidence suggests that these campaigns contribute to meaningful biological outcomes. Furthermore, awareness campaigns are relatively understudied despite their usage as a common approach to mitigating invasive species. We conducted a literature review to assess publications that evaluated the efficacy of public awareness campaigns for managing invasive species. Out of 4382 papers initially extracted for analysis, we determined that 24 of them included studies conducted on awareness campaigns for invasive species. Four public awareness campaigns were deemed a ‘success’, and the other campaigns’ success was indeterminable due to study design. Our study revealed that inconsistencies in defined end points, unclear procedures and variability of campaigns contribute to there being insufficient evidence to determine the efficacy of public awareness campaigns. To evaluate the true efficacy of public awareness campaigns, we recommend that organizations conducting such campaigns implement rigorous and standardized assessments (e.g., Before–After Control–Impact designs or Bayesian analyses) that include measures of not just changes in the knowledge and behaviour of target audiences, but also relevant biological outcomes.
Prospering despite the adverse terms of emancipation? Accumulation of wealth by peasant farmers in the tsarist Russian province of Livonia, 1853–1913
Authors: Lust Kersti
Published: August 2023

The article addresses the issue of wealth accumulation by peasant farmers in the post-emancipation era in the Russian Baltic province of Livonia. The Baltic emancipation schemes stand out as the least beneficial for peasants as they set neither time limits nor land price levels, and the state government did not provide any credit to the purchasers of farms. However, in northern Livonia the nominal value of peasant farmers’ wealth grew as much as tenfold from 1850 to 1913. The study reveals that the advantages and disadvantages of high farm purchase prices should be considered in combination with other factors affecting agricultural growth. In the Baltic context, the large size of the farms, land consolidation, well-developed infrastructure, and the commercialisation of production helped the farm owners amass a relatively large amount of wealth within a generation. Technological improvement also contributed to the rise in productivity and wealth.

Published: August 2023

Introduction:

The Stop the Bleed campaign provided civilians with tourniquet application training and increased the demand for tourniquets among the general population, which led to the development of new commercially available devices. However, most widely available tourniquets have not undergone testing by regulatory bodies and their efficacy remains unknown.

Study Objective:

This study aimed to compare the efficacy and performance of Combat Application Tourniquets (CAT) versus uncertified tourniquets.

Methods:

This study compared 25 CAT with 50 commercially available “look-alike” tourniquets (LA-TQ) resembling the CAT. The CAT and the LA-TQ were compared for cost, size, and tested during one-hour and six-hour applications on a manikin’s leg. The outcomes were force applied, force variation during the application, and tourniquet rupture rate.

Results:

The LA-TQ were cheaper (US$6.07 versus US$27.19), shorter, and had higher inter-device variability than the CAT (90.1 [SE = 0.5] cm versus 94.5 [SE = 0.1] cm; P <.001). The CAT applied a significantly greater force during the initial application when compared to the LA-TQ (65 [SE = 3] N versus 14 [SE = 1] N; P <.001). While the initial application force was maintained for up to six hours in both groups, the CAT group applied an increased force during one-hour applications (group effect: F [1,73] = 105.65; P <.001) and during six-hour applications (group effect: F [1,12] = 9.79; P = .009). The rupture rate differed between the CAT and the LA-TQ (0% versus 4%).

Conclusion:

The LA-TQ applied a significantly lower force and had a higher rupture rate compared to the CAT, potentially affecting tourniquet performance in the context of public bleeding control. These findings warrant increased layperson education within the framework of the Stop the Bleed campaign and further investigations on the effectiveness of uncertified devices in real-world applications.
Product promotions in online supermarkets: prevalence of ‘High Fat Sugar Salt’ (HFSS) products and labelling characteristics
Authors: Wallis Lewis W , Moore Sally G
Published: August 2023

Objective:

To evaluate the prevalence of ‘High Fat Sugar Salt’ (HFSS) products and front-of-pack nutrition labelling (FOPNL) characteristics across promoted products in UK online supermarkets.

Design:

A cross-sectional survey conducted (December 2021–January 2022) on promoted products. Data on ingredients, nutritional composition and display of FOPNL were collected from product webpages. The UK’s Nutrient Profiling Model and Multiple Traffic Light criteria were used to determine HFSS status and possession of inherent red traffic lights (iRTL), respectively. Data analysis determined the prevalence (i.e. percentage of products of the total number of products sampled) of HFSS; FOPNL and possession of iRTL. Chi-squared tests explored associations between these.

Setting:

Three major UK online supermarket retailer websites.

Participants:

Product ‘multibuy’ and ‘entrance’ promotions, from selected product categories.

Results:

Among the sampled 625 promoted products, the prevalence of HFSS was greater in entrance (73 %) compared with multibuy (41 %) promotions (χ2 (1) = 34, P < 0·05), with variations in the former across retailers (49–92 %). The prevalence of HFSS products in multibuy promotions offered by two retailers varied by category (i.e. Confectionery 94–97 %, Yogurts 20–20 %, Soft Drinks 16–33 %, Ready Meals 1·4–18 %). Not all promoted products displayed FOPNL on webpages (70 %) or images (52 %). A number of iRTL were found to be possessed by both HFSS and non-HFSS-promoted products.

Conclusions:

Prior to the 2022 implementation of Regulations restricting these, HFSS products were promoted in online supermarkets with varying display of FOPNL and possession of iRTL. Findings support future policy evaluation and mandatory digital FOPNL.

Objectives

Within the multidisciplinary team, there can sometimes be lack of clarity as to the specific different contributions of each of the psycho-social-spiritual professionals: social workers, psychologist, and spiritual caregivers. This study examined the content of their end-of-life conversations with patients.

Methods

A total of 180 patients with terminal cancer received standard multidisciplinary care, including conversations with a social worker, psychologist, and spiritual caregiver. After each patient’s death, these professionals reported using a structured tool which content areas had arisen in their conversations with that patient.

Results

Across all content areas, there were significant differences between social work and spiritual care. The difference between social work and psychology was slightly smaller but still quite large. Psychology and spiritual care were the most similar, though they still significantly differed in half the content areas. The differences persisted even among patients who spoke with more than 1 kind of professional. The 6 content areas examined proved to subdivide into 2 linked groups, where patients speaking about 1 were more likely to speak about the others. One group, “reflective” topics (inner and transpersonal resources, interpersonal relationships, one’s past, and end of life), included all those topics which arose more often with spiritual caregivers or psychologists. The second group, “decision-making” topics (medical coping and life changes), was comprised of those topics which arose most commonly with social workers, bridging between the medical and personal aspects of care and helping patients navigate their new physical, psychological, and social worlds.

Significance of results

These findings help shed light on the differences, in practice, between patients’ conversations with social workers, psychologists, and spiritual caregivers and the roles these professionals are playing; can aid in formulating individualized care plans; and strengthen the working assumption that all 3 professions contribute in unique, complementary ways to improving patients’ and families’ well-being.

Objectives

This study investigated the challenges and support needs of adults aged 75 and older during and after treatment for a blood cancer to aid targeted supportive resource development.

Methods

Adults aged 75 and older with a blood cancer participated in in-depth, semi-structured interviews about challenges and unmet support needs. Participants recruited through The Leukemia & Lymphoma Society were (1) in treatment or previously in treatment for a blood cancer at age 75 or older and (2) living in the United States or its territories. A thematic analysis was conducted with findings compared between 2 groups: (1) chronic -living with a chronic blood cancer; (2) acute -living with an acute blood cancer or both an acute and chronic blood cancer.

Results

Participants (n = 50) ranged from 75 to 91 years old. Both groups described similar experiences and identified 5 challenges and support needs: (1) socioemotional impact, (2) activities of daily living and instrumental activities of daily living (ADLs/iADLs), (3) uncertainty management, (4) treatment-related stressors, and (5) COVID-19-related strain. Properties for these themes illustrate challenges and support needs, with some differences between groups. For instance, those living with a chronic blood cancer highlighted financial strain with treatment-related stressors, while those with an acute blood cancer focused more on iADLs.

Significance of results

Findings inform an agenda for targeted resource development for older adults with a blood cancer nearing the end of the life span. Results demonstrate the need for supportive services and family communication interventions to help patients manage iADLs and navigate socioemotional needs and challenges.

Context

Depression is common in individuals with cancer and pain, negatively impacts quality of life, treatment adherence, tumor progression, and survival.

Objectives

The primary aims of this study were to (1) evaluate the validity of the Edmonton Symptom Assessment System’s depression (ESAS-D) for detecting major depressive disorder (MDD) as diagnosed by a psychiatrist and (2) identify the best cutoff for this purpose in a sample of cancer pain individuals. The secondary aim was to compare ESAS-D with another commonly used screening measure (Patient Health Questionnaire-2 [PHQ-2]) for classifying individuals as meeting or not meeting Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) criteria for depression.

Methods

49 cancer pain individuals completed the ESAS-D and PHQ-2 Within 2 weeks, a psychiatrist interviewed the participants and determined whether or not they met criteria for MDD based on the DSM-5.

Results

The ESAS-D demonstrated acceptable accuracy and validity for classifying MDD. A cutoff of ≥2 was identified as being best able to balance sensitivity (85%) and specificity (76%) and had an overall accuracy of 79%. A receiver operating characteristic curve analysis showed an area under the curve (AUC) of 0.81 (95% confidence interval [CI]: 0.68–0.94). The ESAS-D also compared favorably with the modified Thai PHQ-2 (sensitivity, 75%; specificity, 72%; overall accuracy, 73%; AUC, 0.74 [95% CI: 0.59–0.88]) for identifying MDD individuals.

Conclusions

The ESAS-D showed acceptable sensitivity, specificity, and overall accuracy for screening for MDD in cancer and pain. It could therefore be used to screen for probable depression in this population.
