Can Rational Emotive Behaviour Therapy (REBT) and Mindfulness be Integrated Effectively within High Performance Settings?
Authors: Young Paul , Chow Vivien , Haslam Cheryl , Wood Andrew , Barker Jamie
Published: August 2022

Our critical commentary explores the overlaps and divergences between Rational Emotive Behaviour Therapy (REBT) and contemporary mindfulness practice and considers whether the approaches could be integrated and applied effectively within two high performance settings in particular: sport and business. It highlights how REBT and mindfulness share similar philosophical positions on the causes of emotional disturbance, on the importance of acceptance, and on cultivating self-awareness to respond healthily and adaptively to adverse events. It also acknowledges diverenges relating to REBT and mindfulness’ respective positions on judgement of thoughts, an emphasis on the present moment, and meditative practice. We observe that by cultivating metacognitive awareness—a capacity to impartially observe thinking—mindfulness may help individuals in high performance settings to see more clearly how their beliefs influence their emotional, cognitive, and behavioural outcomes. Mindfulness could thus potentially aid an individual’s transition from intellectual insight to emotional rational insight within an REBT framework. Moreover, appropriately integrated mindfulness practice alongside REBT-based work may help individuals within high performance settings, and beyond, to cultivate a mindset that is grounded in the present, less distracted and more task focused, potentially enhancing performance outcomes.
New insights into tunnel valley locations and Cenozoic exhumation in the southwestern Baltic Sea based on Machine Learning aided seismic refraction tomography
Authors: Warwel Arne , Hübscher Christian , Ahlrichs Niklas , Schnabel Michael
Published: August 2022

The Cretaceous and Cenozoic evolution of the North German Basin is shaped by complex processes involving basin inversion, uplift and erosion, extension and several periods of Quaternary glaciations. Based on a densely spaced long-offset 2D seismic profile network covering the Bays of Kiel and Mecklenburg, we employ a Machine Learning algorithm to pick refracted first-arrival travel-times. These travel-times are used in a travel-time tomography to derive velocity models for the approximately upper 800 m depth of the subsurface. Investigating velocity-depth relations within the Upper Cretaceous strata and analyzing lateral velocity anomalies within shallow depths provide new insights into the magnitude of the Cenozoic basin exhumation and the locations of glacial tunnel valleys. Our findings suggest that previously observed bent-up structures in seismic images are caused by heterogeneous velocities in the overburden and do not represent actual reflectors. We provide strong indications that these misinterpretations of imaging artifacts are related to tunnel valleys even though these valleys might not always be resolvable in seismic reflection or sediment sub-bottom images. Comparing Upper Cretaceous velocity-depth trends to reference trends reveals significantly higher velocities in our study area. We interpret these differences as overcompaction and estimate the apparent Cenozoic exhumation in the Bay of Mecklenburg to be about 475 m. Within the Bay of Kiel, we observe an increase of the apparent exhumation from about 385 m (south) to about 480 m (north). Our study demonstrates the importance of near surface velocity analysis for the investigation of geological processes in shallow marine settings.
CEO compensation and real estate prices: pay for luck or pay for action?
Authors: Albuquerque Ana , Bennett Benjamin , Custódio Cláudia , Cvijanović Dragana
Published: August 2022

This paper uses variation in real estate prices to study Chief Executive Officer (CEO) pay for luck. We distinguish between pay for luck and pay for responding to luck (action) by exploiting US GAAP accounting rules, which mandate that real estate used in the firm’s operations is not marked-to-market. This setting allows us to empirically disentangle pay for luck from pay for action, as a change in the value of real estate is only accounted for when the CEO responds to changes in property value. We show that CEO compensation is associated with the following two managerial responses to changes in real estate values: (i) real estate sales and (ii) debt issuance. Overall, we show that CEOs are rewarded for taking value-enhancing actions in response to luck.

Swarm is the first European Space Agency (ESA) constellation mission for Earth Observation. Three identical Swarm satellites were launched into near-polar orbits on 22 November 2013. Each satellite hosts a range of instruments, including a Langmuir probe, GPS receivers, and magnetometers, from which the ionospheric plasma can be sampled and current systems inferred. In March 2018, the CASSIOPE/e-POP mission was formally integrated into the Swarm mission through ESA’s Earthnet Third Party Mission Programme. Collectively the instruments on the Swarm satellites enable detailed studies of ionospheric plasma, together with the variability of this plasma in space and in time. This allows the driving processes to be determined and understood. The purpose of this paper is to review ionospheric results from the first seven years of the Swarm mission and to discuss scientific challenges for future work in this field.
Solar Energetic Particles: Spatial Extent and Implications of the H and He Abundances
Authors: Reames Donald V.
Published: August 2022

One of the earliest indicators of the importance of shock acceleration of solar energetic particles (SEPs) was the broad spatial extent of the “gradual” SEP events produced as the shock waves, driven by wide, fast coronal mass ejections (CMEs), expand across the Sun with cross-field transport mediated by the shocks. Contrasting “impulsive” SEP events, with characteristic enhancements of 3He and of heavy elements, are now associated with magnetic reconnection on open field lines in solar jets. However, large shock waves can also traverse pools of residual impulsive suprathermal ions and jets can produce fast CMEs that drive shock waves; in both cases shocks reaccelerate ions with the “impulsive” abundance signatures as well as coronal plasma. These more-complex events produce “excess protons” that identify this process, and recently, differences in the distribution of 4He abundances have also been found to depend upon the combination of seed population and acceleration mode. Extreme differences in the 4He abundances may reflect underlying differences in the abundances of the coronal regions being sampled by solar jets and, surprisingly, SEP events where shock waves sample two seed-particle populations seem to have about twice the 4He/O ratio of those with a single source.

Objectives

To assess survival of patients with muscle-invasive bladder cancer (MIBC) who underwent radical cystectomy (RC) with or without neo-adjuvant chemotherapy (NAC) according to the pathological response at RC.

Methods

965 patients with MIBC (cT2-4aN0M0) who underwent RC with or without NAC were analyzed. Among the collected data were comorbidity, clinical and pathological tumor stage, tumor grade, nodal status (y)pN, and OS. Case–control matching of 412 patients was performed to compare oncological outcomes. Kaplan–Meier curves were created to estimate OS for patients who underwent RC with or without NAC, and for those with complete response (pCR), partial response (pPR), or residual or progressive disease (PD).

Results

Patients with a pCR or pPR at RC, with or without NAC, had better OS than patients who had PD (both p values < 0.001). Moreover, the incidence of pCR was significantly higher in patients receiving NAC prior to RC than in patients undergoing RC only (31% versus 15%, respectively; p < 0.001). Case–control matching displayed better OS of patients who underwent RC with NAC, median survival not reached, than of those who underwent RC only, median 4.5 years (p = 0.023).

Conclusions

This study showed that patients with MIBC who underwent NAC with RC had a significant better OS than those who underwent RC only. The proportion of patients with a pCR was higher in those who received NAC and RC than in those who were treated by RC only. The favorable OS rate in the NAC and RC cohort was probably attributed to the higher observed pCR rate.
Mothers and fathers of pre-school children: a study on parenting stress and child’s emotional-behavioral difficulties

Published: August 2022

The present study aimed to analyze the differences between maternal and paternal parenting stress and children’s behavioral functioning, as determined by teacher and parent reports. In addition, it sought to evaluate the presence of clusters based on parenting stress and to determine whether perceptions of children’s behavioral functioning varied across these clusters. The sample was composed of the parents and teachers of N = 201 children. Parents completed a self-report questionnaire on parenting stress and parents and teachers filled out report-form questionnaires assessing children’s emotional and behavioral functioning. The results showed that mothers had higher levels of parenting stress than fathers, and both parents reported more prosocial behavior in children than did teachers. Furthermore, middle stressed parents had children who expressed more prosocial behavior than did parents in other clusters. The findings also showed that parenting stress influenced partners’ perceptions of children’s behavioral functioning. The multiplicity of child observers facilitated a better understanding of how parenting stress, linked to parent–child interactions, may play an important role in shaping parents’ perceptions of their children.
Modulating the Selectivity of Photocatalytic CO2 Reduction in Barium Titanate by Introducing Oxygen Vacancies
Authors: Wang Yi , Zhang Chengbo , Li Rengui
Published: August 2022

Artificial photosynthetic reduction of CO2 into valuable chemicals is one of the most promising approaches to solve the energy crisis and decreasing atmospheric CO2 emissions. However, the poor selectivity accompanied by the low activity of photocatalysts limits the development of photocatalytic CO2 reduction. Herein, inspired by the use of oxygen vacancy engineering to promote the adsorption and activation of CO2 molecules, we introduced oxygen vacancies in the representative barium titanate (BaTiO3) photocatalyst for photocatalytic CO2 reduction. We found that oxygen vacancies brought significant differences in the CO2 photoreduction activity and selectivity of BaTiO3. The intrinsic BaTiO3 showed a low photocatalytic activity with the dominant product of CO, whereas BaTiO3 with oxygen vacancies exhibited a tenfold improvement in photocatalytic activity, with a high selectivity of ~ 90% to CH4. We propose that the presence of oxygen vacancies promotes CO2 and H2O adsorption onto the BaTiO3 surface and also improves the separation and transfer of photogenerated carriers, thereby boosting the photocatalytic CO2 reduction to CH4. This work highlights the essential role of oxygen vacancies in tuning the selectivity of photocatalytic reduction of CO2 into valuable chemicals.

Published: August 2022

Innovation has become increasingly important for most industries to cope with rapid technological changes as well as changing societal needs. Even though there are many sectors with specific needs when it comes to supporting innovation, the medical technology sector is facing several unique challenges that both increases the lead-time from idea to finished product and decreases the number of innovations that are developed. This paper presents a proposed innovation guide that has been developed and evaluated as a support for the innovation process within medical technology research. The guide takes the unique characteristics of the medical technology sector into account and serves as a usable guide for the innovator. The complete guide contains both a structure for the process and a usable web application to support the journey from idea to finished products and services. The paper also includes a new readiness level, Sect. 4.2 to provide support both when developing and determining the readiness for clinical implementation of a medical technology innovation.
The role of transdisciplinarity for mineral economics and mineral resource management: coping with fallacies related to phosphorus in science and practice
Authors: Scholz Roland W. , Steiner Gerald
Published: August 2022

Mineral economics is a genuine multidisciplinary field dealing with economic and policy matters related to the production, distribution, and consumption of mineral commodities. We discuss why the increasing complexity, ambiguity, ambivalence, and social contestation of subjects of mineral economics promote the participation of mineral economists in transdisciplinary processes. These processes relate (a) knowledge from targeted interdisciplinary processes and (b) mitigated discourses among different stakeholders to provide (c) a shared problem definition and to attain shared basic knowledge about problem transformation science and practice. We discuss known examples of misperceptions regarding minerals (phosphorus), such as an imminent scarcity threat, the incorrectly understood causations of the 2007/2008 price peak and present thephosphorus ore-grades increased by 3.2% between 1983 and 2013 fallacies(which is based on the Simpson’s paradox), andonly few countries have mineable reserves fallacy. Here, we also illuminate motivations underlying several mineral economics–related misunderstandings. We argue that societally relevant questions require an honest mineral economics knowledge brokership. The example of the Global TraPs project, which targeted sustainable phosphorus management, is presented. Honest brokership to attain a clearinghouse function of science requires trust formation in society. We argue that this calls for increasing the understandability of relationships that are not well-understood, such as “if prices rise, so do stocks.” Wellmer and Becker-Platen’s feedback control cycle may be considered an example of how complex mineral economics can become and how challenging it is to be understandable to scientists from different disciplines and faculties as well as to practitioners whose knowledge may well be used to cope with the complexity of given problems. Thus, the present paper represents a plea for mutual learning between science and practice in order to understand the complex social and economic challenges of mineral resource dynamics.

Published: August 2022

The impacts of global climate warming on maize yield vary regionally. However, less is known about how soil modulates regionally specific impacts and soil properties that are able to alleviate adverse impacts of climate warming on maize productivity. In this study, we investigated the impacts of multiple soil inherent properties on the sensitivity of maize yield (SY,T) to growing season temperature across China. Our results show that a 1°C warming resulted in the largest yield decline (11.2 ± 6.1%) in the mid-eastern region, but the moderate yield increase (1.5 ± 2.9%) in the north-eastern region. Spatial variability in soil properties explained around 72% of the variation in SY,T. Soil organic carbon (SOC) content positively contributed the greatest extent (28.9%) to spatial variation of SY,T, followed by field capacity (9.7%). Beneficial impacts of increasing SOC content were pronounced in the north-eastern region where SOC content (11.9 ± 4.3 g kg−1) was much higher than other regions. Other soil properties (e.g., plant wilting point, sand content, bulk density, and saturated water content) were generally negatively correlated with SY,T. This study is the first one to answer how soil inherent properties can modulate the negative impacts of climate warming on maize yield in China. Our findings highlight the importance of SOC in alleviating adverse global warming impacts on maize productivity. To ensure food security for a rapidly increasing population under a changing climate, appropriate farming management practices that improve SOC content could reduce risk of adverse effects of global climate warming through a gain in yield stability and more resilient production in China’s maize belt.
Improved fault location method for AT traction power network based on EMU load test
Authors: Lin Guosong , Fu Xuguo , Quan Wei , Hong Bin
Published: August 2022

The autotransformer (AT) neutral current ratio method is widely used for fault location in the AT traction power network. With the development of high-speed electrified railways, a large number of data show that the relation between the AT neutral current ratio and the distance from the beginning of the fault AT section to the fault point (Q–L relation) is mostly nonlinear. Therefore, the linear Q–L relation in the traditional fault location method always leads to large errors. To solve this problem, a large number of load-related current data that can be used to describe the Q–L relation are obtained through the load test of the electric multiple unit (EMU). Thus, an improved fault location method based on the back propagation (BP) neural network is proposed in this paper. On this basis, a comparison between the improved method and the traditional method shows that the maximum absolute error and the average absolute error of the improved method are 0.651 km and 0.334 km lower than those of the traditional method, respectively, which demonstrates that the improved method can effectively eliminate the influence of nonlinear factors and greatly improve the accuracy of fault location for the AT traction power network. Finally, combined with a short-circuit test, the accuracy of the improved method is verified.
Shifting landscapes of digital literacy
Authors: Bacalja Alexander , Beavis Catherine , O’Brien Annemaree
Published: August 2022

This paper explores how changing digital literacy practices in educational contexts require that we continually revisit conceptualisations of digital literacy education. We begin by analysing the positions taken by stakeholders who contribute to digital literacy discourses in Australia, exploring how competing interests produce effects which manifest in ways that differently consecrate social and cultural practice in the digital age. We advocate the need for pedagogic frameworks that support digital literacy education. Existing approaches tend to privilege the operationalisation of digital technology. By contrast, teaching is needed which focusses on meaning-making and creating. However, the ‘datafication of everyday life’ (Barassi, 2018, p.170) has included extraordinary interventions into schooling that have significant implications for teachers and students. We argue that preparing young people for digital citizenship must include a focus on critical digital literacies that are responsive to contemporary digital forces (e.g. platformatisation, artificial intelligence, edu-apps, algorithms) as well as those digital technologies that are yet to make their way into formal schooling.
Calibration of safety factors for prestressed stayed steel columns
Authors: Hyman Peter , Sriramula Srinivas , Osofero Adelaja I.
Published: August 2022

Previous studies have investigated the behaviour of prestressed stayed steel columns with a view to developing design guidelines. As most of the modern standards move towards calibrated safety factors, there is a need to explore the design expectations of these structures from a probabilistic perspective. This has not been studied in the literature till now, perhaps due to lack of clarity on underlying uncertainties, failure models and reliability levels. In this paper, the relevant reliability levels were studied to highlight the critical modes for such structures. A sensitivity analysis was performed on the random variables to investigate their impact on the model output. The reliability levels found through appropriate analysis were then compared with target reliabilities to calibrate partial safety factors to be used in the design of these structures. A range of safety factor values were found depending on the conditions adopted in the calibration and target reliability studies.
Spanish Translation, Transcultural Adaptation, Validation and Clinical Applicability of Female Genital-Self Image Scale (FGSIS)
Authors: Bartolomé Alba , Villalaín Cecilia , Bermejo Rocío , Bolívar Ana Belén , Castillo Laura Pilar , Galindo Alberto , Tejerizo Álvaro
Published: August 2022

Background

As female genital cosmetic surgeries have significantly increased, appropriate tools to evaluate self-esteem about women's own genitalia are necessary.

Aim

to translate, culturally adapt to Spanish women and to evaluate the psychometric properties of the Female Genital Self-Image Scale (FGSIS).

Methods

FGSIS was forward and backward translated, culturally adapted into Spanish and its content evaluated through Delphi consensus. One item from the original scale was discarded after expert panel evaluation, developing the final Spanish scale (FGSIS-S) consisting of 6 items. Its psychometric properties were evaluated among 202 women attending gynecological consults through an online survey. The survey included socio-demographic data and FGSIS-S.

Main Outcome Measure

Socio-demographic items, psychometric characteristics of the FGSIS-S (construct evaluation, internal consistency and test-retest reliability) were assessed.

Results

FGSIS-S proved to relate appropriately with the proposed construct (sum-content validity index 0.9, and significant inverse correlation with women concerned about their genital appearance or considering cosmetic surgery) with a 1-factor solution on exploratory factor analysis. The test proved good internal consistency (McDonald's omega 0.86) and test-retest reliability (intraclass correlation 0.86, P < .001). In 41.1% of cases, women referred concern about their genital's self-image and in 12.4% had considered undergoing cosmetic surgery.

Clinical Translation

The validated version of FGSIS-S can help both professionals and patients, and its implementation can be easily made in gynecological consults.

Strengths and Limitations

The main limitation is a self-selection bias in women attending gynecological consults, who may be more worried about their gynecological/sexual health. The sample is also a relatively homogeneous Caucasian population, with medium-high educational level, coming from gynecological consults. Strengths include the large sample size and the demographic survey that permitted evaluating the performance of FGSIS-S in the context of concern about genitals or consideration of cosmetic surgery.

Conclusion

FGSIS-S is an adequate scale to measure women's genital image self-perception in Spanish-speaking population of Spain.
The rhetoric of reaction redux
Authors: Sunstein Cass R.
Published: August 2022

In The Rhetoric of Reaction, published in 1991, Albert Hirschman identified three standard objections to reform proposals: perversity, futility and jeopardy. In Hirschman's account, these objections define reactionary rhetoric. A proposal would be “perverse” if it would aggravate the very problem it is meant to solve; it would be “futile” if it would not even dent the problem; it would produce “jeopardy” if it would endanger some other goal or value (such as liberty or economic growth). The rhetoric of reaction comes from both left and right, though in Hirschman's account, it is a special favorite of the right. In recent years, the perversity, futility and jeopardy theses have often been invoked to challenge reforms, including nudges. While the three theses are sometimes supported by the evidence, they are often evidence-free speculations, confirming Hirschman's suggestion that the rhetoric of reaction has “a certain elementary sophistication and paradoxical quality that carry conviction for those who are in search of instant insights and utter certainties.”
Dynamics of sediment-laden plumes in the ocean
Authors: Mingotti Nicola , Woods Andrew W.
Published: August 2022

We present a series of experiments to illustrate the dynamics of positively or negatively buoyant particle-laden plumes in a cross-flow, with relevance for the discharge of sediment into the ocean during deep-sea mining operations. In an unstratified ambient fluid, our experiments identify three different regimes, corresponding to (i) a dense particle-laden plume, host to relatively dense saline fluid, in which the particles separate from the descending plume as the flow speed falls below the particle settling speed; (ii) a dense particle-laden plume, host to buoyant fluid, in which the fluid gradually rises from the sinking plume of particles, to form a second rising plume of source fluid; and (iii) a buoyant particle-laden plume, host to buoyant fluid, which rises from the discharge pipe, and from which particles gradually sediment. Classical models of single-phase plumes describe the initial motion of the plumes in cases (i) and (iii), but as the flow speed falls below the particle fall speed, sedimentation leads to a change in the averaged buoyancy, and, hence, the plume speed. Our data also suggest that the sedimentation leads to a reduction in the rate of entrainment of ambient fluid, compared with the classical single-phase plumes. We also show that with a density stratified ambient fluid, the stratification may arrest the plume prior to significant particle sedimentation, and in this case, the plume tends to spread downstream at the level of neutral buoyancy where particle sedimentation proceeds. The bulk density of the residual plume fluid may then remain intermediate between the density of the upper and lower layer fluid, or may become less dense than the upper layer fluid, in which case, following sedimentation, the plume fluid rises through the upper layer. While the dynamics of deep-sea mining plumes in the ocean are more complex, for example, owing to background turbulence and mixing, the results of our new laboratory experiments highlight the range of flow processes which may influence the initial dispersion and sedimentation of particles in such plumes following release into the water, depending on the initial conditions, the ambient density and the particle fall speed. We also discuss the relevance of our work in the context of ash dispersal by volcanic plumes.
Performing Crisis? Trump, Populism and the GOP in the Age of COVID-19
Authors: Roberts Kenneth M.
Published: August 2022

Although populist figures are often thought to thrive during crises that allow them to ‘perform’ decisive leadership, the US experience under Donald Trump during the COVID-19 crisis demonstrates that the opposite may sometimes occur. Despite its scientific and medical prowess, the US suffered more coronavirus cases and deaths than any other country in the world during the first year of the pandemic, and this abysmal performance was largely attributable to a failure of government. Fixated on the pandemic's economic effects and its potential political fallout, the Trump administration's framing of the crisis tried to minimize the public health emergency, externalize blame through a focus on the Chinese scapegoat and accuse the media and Democrats of hyping the pandemic to undermine Trump's presidency. In responding to the pandemic, Trump and his allies cast doubt on scientific and medical expertise that called for more aggressive testing, mask wearing and social-distancing measures. Trump delegated responsibility for crisis management to subnational governments and the private sector, and he politicized their efforts to regulate social behaviour in the public interest, intensifying partisan polarization.
Quasi-dynamic subgrid-scale kinetic energy equation model for large-eddy simulation of compressible flows
Authors: Qi Han , Li Xinliang , Hu Running , Yu Changping
Published: August 2022

A quasi-dynamic subgrid-scale (SGS) kinetic energy one-equation eddy-viscosity model is introduced in this paper for large-eddy simulation (LES) of compressible flows. With the additional SGS kinetic energy equation, the SGS kinetic energy can be predicted properly. Then, using the dual constraints of SGS kinetic energy and the SGS kinetic energy flux, the eddy-viscosity model can be determined exactly. Taking a similar scheme as the expansion of the SGS stress, other unclosed quantities in the equations to be solved could be well modelled separately. Therefore, with the advance of the equations, all the model coefficients can be determined dynamically. Differing from the classic dynamic procedure, the new methodology needs no test filtering, and thus it could also be called a quasi-dynamic procedure. Using direct numerical simulation of compressible turbulent channel flow, the$a$ $priori$test shows that the key modelled quantities of the suggested model display high correlations with the real values. In LES of compressible turbulent channel flows of the Mach number being$1.5$and 3.0, the proposed model can precisely predict some important quantities, including the mean velocity, Reynolds stress and turbulent flux, and it can also supply more abundant turbulent structures. For the compressible flat-plate boundary layer, the new model can correctly predict the transition process, mean velocity and turbulence intensities in the turbulent region. The results show that the proposed model has the advantage of scale adaptivity. Finally, the new model is applied to LES of turbulent mixing in spherical converging Richtmyer–Meshkov instability, and the accurate results show that the new model has a good ability for LES of complex fluids.

Published: August 2022

The present study aimed to assess the prevalence of food insecurity (FI) among college students and explore its association with indicators of mental and psychosocial health. Data were collected using a cross-sectional online survey from college students in different universities in Lebanon during the Spring 2021 semester. FI was assessed using the validated eight-item food insecurity experience scale. The mental health of college students was assessed using validated screening tools for depression, anxiety and well-being, namely the Patient Health Questionnaire (PHQ-9), the General Anxiety Disorder-7 (GAD-7) and the World Health Organization (WHO-5) index, respectively. Multiple linear regression models were conducted to assess the relationship of FI with PHQ-9, GAD-7 and WHO-5 scores. A total of 745 students completed the online survey. Approximately 39 % of students in the sample were experiencing FI of which 27·4, 8·1, and 3·5 % were experiencing mild, moderate and severe FI , respectively. Low maternal education, low household monthly income and high levels of stress were significant correlates of FI among college students (P-trend < 0·001). In addition, 22·6 and 34·4 % of students showed severe symptoms of depression and anxiety, respectively. Regression models showed that FI was associated with higher scores on PHQ-9 and GAD-7 (β = 2·45; 95 % CI [1·41, 3·49]) and (β = 1·4; 95 % CI [1·1, 2·2], respectively) and lower scores on WHO-5 (β = −4·84; 95 % CI [−8·2, −1·5]). In conclusion, a remarkable proportion of college students reported experiencing different forms of FI, which was associated with poorer mental health and well-being outcomes. Public health programmes and interventions are needed to mitigate FI and improve student health-related outcomes.
Brain activity during pursuit and goal-conflict threat avoidance in major depressive disorder
Authors: Marwood Lindsey , Wise Toby , Kerr-Gaffney Jess , Strawbridge Rebecca , Williams Steve C R , Cleare Anthony J , Perkins Adam
Published: August 2022

Threat avoidance is a prominent symptom of affective disorders, yet its biological basis remains poorly understood. Here, we used a validated task, the Joystick Operated Runway Task (JORT), combined with fMRI, to explore whether abnormal function in neural circuits responsible for avoidance underlies these symptoms. Eighteen individuals with major depressive disorder (MDD) and 17 unaffected controls underwent the task, which involved using physical effort to avoid threatening stimuli, paired with mild electric shocks on certain trials. Activity during anticipation and avoidance of threats was explored and compared between groups. Anticipation of aversive stimuli was associated with significant activation in the dorsal anterior cingulate cortex, superior frontal gyrus, and striatum, while active avoidance of aversive stimuli was associated with activity in dorsal anterior cingulate cortex, insula, and prefrontal cortex. There were no significant group differences in neural activity or behavioral performance on the JORT; however, participants with depression reported more dread while being chased on the task. The JORT effectively identified neural systems involved in avoidance and anticipation of aversive stimuli. However, the absence of significant differences in behavioral performance and activation between depressed and non-depressed groups suggests that MDD is not associated with abnormal function in these networks. Future research should investigate the basis of passive avoidance in major depression. Further, the JORT should be explored in patients with anxiety disorders, where threat avoidance may be a more prominent characteristic of the disorder.
Genes, personality, and political behavior
Authors: Weinschenk Aaron , Dawes Christopher , Klemmensen Robert , Rasmussen Stig Hebbelstrup Rye
Published: August 2022

Abstract

In this article, we examine whether there is genetic overlap between personality traits and political participation, interest, and efficacy. We make several contributions to the literature. First, we use new data from a large sample of twins from Denmark to examine the link between genes, the Big Five traits, and political behavior. Previous research in this area has not examined the Danish context. Second, because our measures have some overlap with those used in previous studies, we are able to examine whether previous findings replicate in a different sample. Finally, we extend the literature by examining the possible genetic link between some personality and political traits that have not yet been explored. Overall, we find that genes account for a fairly large share of the correlation between two of the Big Five personality traits (openness and extraversion), political participation, and political interest. Thus, most of the relationship between these personality traits and our measures of political behavior can be accounted for by a common underlying genetic component.
Historicizing Economic Growth: An Overview of Recent Works
Authors: Bivar Venus
Published: August 2022

In this historiographical review, I analyse recent works on the history of economic growth and provide a starting point for thinking about how this literature fits together as a discrete field of research. The questions being asked in these texts are relatively new, and as of yet no attempt has been made to identify the major themes that are driving this research. In putting these works into dialogue with each other, across the disciplinary boundaries of history, ecology, anthropology, economics, and political science, we can see that a new subfield of academic inquiry is emerging. Driven by concerns over climate change and rising economic inequality, this new research aims to understand the obsession with economic growth that has shaped so much of our contemporary world.
Balance testing: does it make a difference?
Authors: Watts E , Lindley K , Irving R , Dalton L
Published: August 2022

Objective

This study aimed to analyse whether referral for specialist balance testing influences diagnosis and management of patients with dizziness.

Method

This was a retrospective study examining patients referred for vestibular function testing between 1 January 2018 and 30 June 2018.

Results

A total of 101 patients were referred, with 69 patients (68.3 per cent) receiving a preliminary ‘pre-vestibular function testing balance diagnosis’, which included benign paroxysmal positional vertigo (32.7 per cent), Ménière's disease (13.8 per cent) and migraine (14.9 per cent). Following vestibular function testing, revised diagnoses were achieved for 54 patients (53.5 per cent), including benign paroxysmal positional vertigo (14.9 per cent), Ménière's disease (3.0 per cent) and migraine (10.9 per cent). Pre-vestibular function testing balance diagnoses were confirmed for 32.4 per cent of patients. If no pre-vestibular function testing suspected diagnosis was provided, vestibular function testing was significantly more likely to be inconclusive. Following vestibular function testing, 38.6 per cent were discharged, 21.7 per cent were referred to another specialty and treatment was commenced for 17.8 per cent of patients.

Conclusion

Referral for vestibular function testing has a role when attempting to answer a clear clinical question. Diagnosing the underlying aetiology of complex imbalance is challenging, but diagnosis can be assisted by judicious use of vestibular function testing.

The present study aims to investigate the reproductive biology of the small pelagic Sardinella aurita Valenciennes, 1847 in the Canary Islands, to enable its reliable assessment and advise on appropriate management measures for a fishing resource showing a declining trend in landings. Reproductive biology and sexual patterns of round sardinella were examined from monthly random samples of commercial catches landed by the artisanal purse-seine fleet. The landings' length frequencies, ranging between 9–32 cm (based on the total lengths, TL), were recorded from 2013–2019. The overall mean value of TL was 20.9 cm, with annual mean values between 20–22 cm, except in 2016 (TL = 19 cm). The overall sex ratio M:F was 1:0.92, with males significantly predominant. Sex ratios fluctuated as a function of size and month: females were more abundant in the larger length classes, as well as before and after spawning, whereas males were more abundant in the smaller length classes and during spawning. Based on gonad maturity stages and gonadosomatic index, round sardinella spawns during almost all the year, with a peak in January–February and a resting period during October–November. The length at first maturity was estimated at TL of 18.2 cm, notably smaller than the value obtained for the NW African coastal waters where the demographic structure in round sardinellas' landings is totally different.
How African conceptions of God bear on life's meaning
Authors: Metz Thaddeus
Published: August 2022

Up to now, a very large majority of work in the religious philosophy of life's meaning has presumed a conception of God that is Abrahamic. In contrast, in this article I critically discuss some of the desirable and undesirable facets of Traditional African Religion's salient conceptions of God as they bear on meaning in life. Given an interest in a maximally meaningful life, and supposing meaning would come from fulfilling God's purpose for us, would it be reasonable to prefer God as characteristically conceived by African philosophers of religion to exist instead of the Abrahamic conception of God? At this stage of enquiry, I answer that, in respect of the range of people to whom God's purpose would apply, a more African view of God would plausibly offer a greater meaning, but that, concerning what the content of God's purpose would be, the Abrahamic view appears to offer a greater one. I conclude by reflecting on this mixed verdict and by suggesting respects in which non-purposive facets of the African and Abrahamic conceptions of God could also have implications for life's meaning.
Child phonological responses to variegation in adult words: A cross-linguistic study

Variegation – the presence of more than one supraglottal consonant per word – is a key challenge for children as they increase their expressive vocabulary toward the end of the single-word period. Here we consider the prosodic structures of target words and child forms in English, Finnish, French, Japanese and Mandarin to determine whether children learning these languages respond similarly to the challenge or instead differ in ways related to the phonological structure of the adult language. Based on proportional occurrence of each structure, we find that the word forms of children learning Mandarin and Japanese show more variegation than do those of children learning the European languages, although their target words do not; proportions of reduplication, consonant harmony and single-consonant words also differ by language. We conclude that experience with the structure of the language – and thus representation, as well as immature articulatory skills – shapes children’s responses to variegation.
Changing pronoun interpretations across-languages: discourse priming in Spanish–English bilingual speakers
Authors: Contemori Carla , Minjarez Oppenheimer Natalia I.
Published: August 2022

Are bilingual speakers’ representations of pronominal expressions completely independent in the two languages, or is there sharing of discourse-level representations cross-linguistically? In the present study, we address this question by using a sentence comprehension task that implements the cross-linguistic priming technique at the discourse-level.

In two experiments conducted with Spanish–English bilinguals, we prime dis-preferred interpretations for ambiguous pronouns in the second language (English) by using first language (Spanish) pronoun interpretation primes. In experiment 1, Spanish null pronouns prime second-mentioned/object interpretations in English, showing an effect of priming. In experiment 2, Spanish explicit pronouns prime second-mentioned/object interpretations in English, indicating that an effect of priming approaches significance.

The results demonstrate that bilinguals’ inferences about probability distributions and coherence relations are susceptible to cross-linguistic influence. The strength of the priming effect is discussed within models of cross-language abstract representations.
Face in late imperial China's diplomacy with the United States: Minister Cui Guoyin's approach to Chinese exclusion
Authors: Zhang Tao
Published: August 2022

As the Chinese minister to the United States between 1889 and 1893, Cui Guoyin faced unprecedented pressures from the Qing government to achieve an alleviation of Chinese exclusion. However, American discrimination against Chinese escalated despite his tireless effort to stem it. The failure made him frustrated and especially sensitive to the issue of face. While finding it a useful tool to exonerate himself, Cui believed that face could also be helpful to Chinese bargaining with the United States over immigration. He incorporated this belief into his exchanges with the U.S. Department of State. At Cui's suggestion or at least agreeing with him, the Zongli Yamen referred to America's reputation as a pressure for concessions in its communications with the U.S. legation in Beijing as well. Such “weaponization” of face represents both an often ignored backward turn in late Qing's diplomatic mentality and the limit of its diplomatic leverage with the United States.
Can criminal organizations be non-State parties to armed conflict?
Authors: Kalmanovitz Pablo
Published: August 2022

The motivations of armed groups are widely considered to be irrelevant for the applicability of international humanitarian law (IHL). As long as organized violence is of sufficient intensity, and armed groups have sufficient capacity to coordinate and carry out military operations, there is an armed conflict for purposes of international law. It follows that large-scale criminal organizations can, in principle, be treated legally on a par with political insurgent groups. Drug cartels in particular, if sufficiently armed and well organized, can constitute armed opposition groups in the legal sense when their confrontation with State forces is sufficiently intense. This article problematizes this interpretation. It corroborates standing legal doctrine in finding that subjective motives are not a sound basis to exclude the application of IHL, but it argues that a workable distinction can be made between the strategic logic and the organizational goals of criminal groups and those of political insurgents. Drawing on a growing body of empirical studies on the political economy of criminal violence, a strong presumption is defended against qualifying as armed conflict organized violence involving criminal organizations.
