Affirming or contesting white innocence? Anti-racism frames in grassroots activists’ accounts

ABSTRACT Although anti-racism is recognized as a heterogeneous phenomenon, there are few studies that provide analytical tools to grasp the differences between anti-racisms in more detail. This study contributes to the analytical discussion on anti-racism through an analysis of grassroots activists’ views on their anti-racism. The data, interviews with 46 grassroots anti-racist activists based in Finland, is explored through a frame analysis. This article argues that meaning-making on racism and anti-racism is tied to conceptions of racial space. The argument is presented through an empirical typology of three anti-racist frames: defence, recognition and redistribution. Distinguishing between the defence, recognition, and redistribution frames enables an understanding of how anti-racisms assume a supposedly “race-neutral” space of white innocence and contest distinct dimensions of racial divides.
The Rise of Reddit: How Social Media Affects Retail Investors and Short-sellers’ Roles in Price Discovery

Using data from social media platform Reddit from 2020 and 2021, we examine how stock prices, retail trading and short-selling are inter-connected with social media activity. More Reddit traffic, more positive tones, more disagreement and higher connectedness at Reddit lead to higher returns, higher retail order flow, and lower shorting flows on the next trading day. The information content of the social activity variables is different from that of retail order flows and shorting flows, and they are each a significant predictor for future returns. Interestingly, when there is higher traffic, more positive tone, more disagreement and higher connectedness on Reddit, the shorting flows become even more informative and predict even lower future returns. A closer look at Robinhood 50 stocks shows that these stocks are more affected by social media activity. Positive retail order flows predict even higher future returns for these stocks, while heavy shorting flows in these stocks also more significantly predict low future returns.
Pattern Recognition: Impact of Exercises Modes on Developing a Small Ball Throwing Skill in Boys Aged 8

The purpose of the study was to determine the impact of exercises modes on developing a small ball throwing skill in boys aged 8. Materials and methods. The study participants were 21 boys aged 8, who were randomly divided into three groups of 7 people. The children and their parents were fully informed about all the features of the study and gave their consent to participate in the experiment. The study examined the influence of the number of repetitions on the effectiveness of teaching boys aged 8 throwing a small ball at a target. A pedagogical experiment examined the influence of 6, 12, and 18 repetitions with a 60-second rest interval on the increase in the level of proficiency in exercises of boys aged 8. In the first group, the boys repeated the task 6 times with a rest interval of 60 s, in the second group – 12 times with a rest interval of 60 s, in the third group 18 times with a rest interval of 60 s. When teaching throwing exercises during the class, the study evaluated the level of proficiency by the alternative method (“performed”, “failed”) and calculated the probability of exercise performance (p = n/m, where n is the number of successful attempts, m is the total number of attempts). In teaching boys aged 8, the method of algorithmic instructions was used. The next exercise started after three successful attempts. Throwing a ball at a vertical target was taught. The study materials were processed by the IBM SPSS 20 statistical analysis software. During discriminant analysis, a prognostic model for group membership was created. Results. Discriminant analysis made it possible to determine the impact of the number of repetitions on the effectiveness of developing the skills of throwing a small ball at a target; answer the question as to how significantly the modes of repetitions differ by the effectiveness of motor skills development, what class the object belongs to based on the values of discriminant variables. Conclusions. Based on the analysis of group centroids, it was found that in boys aged 8, six repetitions of the exercise (6 sets one time with a rest interval of 60 s) significantly influence the increase in the level of proficiency in exercises during physical education lessons. The results of group classification show that 85.7% of the original grouped observations were classified correctly.
Middle Ordovician (middle Darriwilian) Archaeospicularia and Entactinaria (radiolarians) from the Table Cove Formation, Piccadilly Quarry, Newfoundland, Canada

Abstract. New, distinctive, well-preserved and previously undescribed constituents of a Middle Ordovician (middle Darriwilian, Dw2) radiolarian assemblage from the Table Cove Formation in Newfoundland are described. Three-dimensional X-ray micro-computed tomography (µ-CT) facilitates detailed examination of key specimens revealing hitherto unknown details of the internal morphologies of key lower Paleozoic taxonomic groups, among which a lack of knowledge has previously impeded resolution of higher taxonomic rankings. Twenty-seven archaeospiculid and entactinarian taxa are described and illustrated including six new species: Westernbrookia polygonata n. sp. , Neopalaeospiculum piccadilliensis n. sp. , Ramuspiculum laxum n. sp. Spongentactinia nazarovi n. sp. , Aspiculum irregulare n. sp. , and Nyfrieslandia ramosissima n. sp. The investigation extends the known ranges of the species: Pararcheoentactinia reedae Won and Iams, 2002; Sphaeroentactinia robusta Won and Iams, 2015; Varispiculum ectospiculatum Won and Iams, 2015; and Svalbardospiculum multifurcatum (Won, Iams, and Reed, 2005), together with the genus Echidnina to the mid-Darriwilian.
A worldwide sectorial analysis of sustainability reporting and its impact on firm performance

ABSTRACT This study investigates the worldwide impact of sustainability reporting on firms' performance across seven different sectors. Using data culled from 3,000 firms in 80 different countries for ten years from 2008 to 2017 (cumulatively 23,738 observations). The findings elicited from the empirical results demonstrate that there are differences in the impact of sustainability reporting (ESG) on firm's operational performance (ROA), financial performance (ROE) and market performance (TQ) between the seven sectors. Inasmuch as it contributes to the literature of sustainability accounting by a systematic depiction of cross-sectorial ESG reporting, this study establishes a benchmark to guide to firms wishing to adopt sustainability reporting. Moreover, in including macroeconomic variables, the study provides a fresh perspective to the literature of the on the economic implications of sustainability disclosure.
Paradoxical Sensitivity to Sub-threshold Asynchronies in Schizophrenia: A Behavioral and EEG Approach

The flow of consciousness is disrupted and disorganized in schizophrenia. We explore the hypothesis that this disruption is related to asynchronies not being predicted in advance and standing out instead of being integrated in the flow of events. We recorded EEG continuously during a simultaneity/asynchrony discrimination task, in which subjects decide whether 2 squares are shown simultaneously or with an asynchrony (asynchronies were between 24 and 96 ms). Behavioral data was obtained in 32 patients with schizophrenia and 27 matched controls, and EEG was recorded in a subset of 17 patients vs 15 controls. Two results suggested a lack of asynchrony prediction in patients. Behavioral difficulties at detecting asynchronies increased in patients with schizophrenia relative to controls after a detection of simultaneity, and this effect was correlated with clinical disorganization. Desynchronization of alpha activity observed before the beginning of a trial was larger after asynchronous than simultaneous responses in controls, but not in patients. EEG signals additionally suggested abnormal sensitivity to short asynchronies in patients. The amplitude of early signals around 180 ms after the first square abnormally increased in patients for short asynchronies relative to perfect simultaneity, whereas EEG signals at parietal regions decreased in amplitude in patients relative to controls, in the 400–600 ms interval after the first square. These results reinforce the hypothesis of time prediction and sequencing impairments at the sub-second level and may provide an explanation for the disruption of the patients’ consciousness flow.
Malaysian Youth eHealth Literacy via Healthcare Websites: A Study on Factors Forming Sexual and Reproductive Health Information-seeking Intention

Extensive research has been carried out to study the relationship between Malaysian youth and their perceptions of sexual and reproductive health (SRH); ranging from knowledge and awareness levels to lifestyle choices. However, there is insufficient information on youth e-health literacy levels on the subject matter. Therefore, this study examines the factors that influence youth intention towards using healthcare websites to search for SRH information. This study is guided by the Theory of Reasoned Action (TRA) which suggests that the best indicator of behaviour is intention, which is formed by attitude and subjective norms. Participants for the study were 400 youth (from 18 – 40 years of age) based in the Klang Valley area. Data was collected through a self-administered questionnaire where the research instruments were adopted from the TRA framework, namely: Attitude, Subjective Norms, and Intention. Overall, the findings showed that youth who had positive attitudes and adequate social support/pressure towards using healthcare websites to find SRH information were likely to have a high intention to do so. One crucial finding in the context of this study is how subjective norms are a stronger predictor of SRH information-seeking intention compared to attitude. This finding here can add a new dimension to how the TRA framework is utilised, especially in studies revolving around Asian youth intentions and behaviours. Ministries, NGOs, and private institutions that advocate better SRH practices in Malaysia should leverage the influence of new media to improve health literacy levels among youth.
Effects of Different Inflow Rate Patterns and Distributions of Grass Strips on Runoff and Sediment in an Engineering Accumulation Body

Engineering accumulation bodies are critical sources of artificial soil and water loss. The objectives of this study were to evaluate the effects of different inflow rate patterns and distributions of grass strips on runoff and sediment in engineering accumulation bodies. A field runoff plot (20 m long, 1 m wide, and 0.5 m deep) was used for inflow simulation experiments under four inflow rate patterns (even, rising, falling, and rising-falling) and five grass strip patterns (patterns Ⅰ-Ⅴ). The results showed that the changing trends of runoff rate and sediment yield increased with increasing inflow rate and decreased with reduction for the same grass strip pattern. Although the inflow rate pattern affected runoff and sediment yield, it had no significant effect on the total runoff and sediment. The influence of the grass strip pattern on runoff and sediment was significantly higher than that of the inflow rate pattern. The runoff reduction and sediment reduction effects of grass strip patterns were 12.23 to 49.62% and 12.92 to 80.54%, respectively. When grass strips were distributed on a slope in bands (pattern Ⅴ), the soil and water conservation effects were ideal, reducing the average runoff and sediment by 44.98% and 58.09%, respectively. Sediment reduction caused by decreasing runoff (SRR) was the main factor controlling erosion and sediment yield. This study can guide the configuration of vegetation control measures for soil and water loss in engineering accumulation bodies.
The Atlantic Jet Response to Stratospheric Events: A Regime Perspective

The tropospheric response to Sudden Stratospheric Warmings (SSWs) is associated with an equatorward shift in the midlatitude jet and associated storm tracks, while Strong Polar Vortex (SPV) events elicit a contrasting response. Recent analyses of the North Atlantic jet using probability density functions of a jet latitude index have identified three preferred jet latitudes, raising the question of whether the tropospheric response to SSWs and SPVs results from a change in relative frequencies of these preferred jet regimes rather than a systematic jet shift. We explore this question using atmospheric reanalysis data from 1979 to 2018 (26 SSWs and 33 SPVs), and a 202‐years integration of the Whole Atmosphere Community Climate Model (92 SSWs and 68 SPVs). Following SSWs, the northern jet regime becomes less common and the central and southern regimes become more common. These changes occur almost immediately following “split” vortex events, but are more delayed following “displacement” events. In contrast, the northern regime becomes more frequent and the southern regime less frequent following SPV events. Following SSWs, composites of 500‐hPa geopotential heights, surface air temperatures, and precipitation most closely resemble composites of the southern jet regime, and are generally opposite in sign to the composites of the northern jet regime. These comparisons are reversed following SPVs. Thus, one possible interpretation is that the two southernmost regimes appear to be favored following SSWs, while the southernmost regime becomes less common following SPVs.
The flexible impact of member affect in groups performing complex decision-making tasks

Positive and negative affect are often thought to influence the quality of group decision-making by prompting different cognitive processing styles: a less effortful heuristic style in the case of positive affect, and a more detail-oriented systematic style in the case of negative affect, with the latter yielding better group decisions than the former. By contrast, we argue that rather than prompting a specific cognitive processing style, positive affect encourages the maintenance of whatever style is currently in use, while negative affect encourages a change in style. Consequently, both positive and negative affect can result in either better or worse group decisions, depending on which cognitive processing style was at play just prior to the affect’s arousal. To test this idea, we conducted three experiments, and found that when heuristic processing was initially primed, subsequently inducing a sad mood resulted in better decisions by both individuals and groups than did subsequently inducing a happy mood. The reverse occurred when systematic processing was initially primed. In groups, these effects were mediated by the relative focus, during group discussion, on critical decision-relevant information. Implications of these findings and future directions for research are discussed.
Testing of the foreshock hypothesis within an epidemic like description of seismicity

The epidemic type aftershock sequence (ETAS) model provides a good description of the post-seismic spatio-temporal clustering of seismicity and is also able to capture some features of the increase of seismic activity caused by foreshocks. Recent results, however, have shown that the number of foreshocks observed in instrumental catalogues is significantly much larger than the one predicted by the ETAS model. Here we show that it is possible to keep an epidemic description of post-seismic activity and, at the same time, to incorporate pre-seismic temporal clustering, related to foreshocks. Taking also into-account the short-term incompleteness of instrumental catalogues, we present a model which achieves very good description of the southern California seismicity both on the aftershock and on the foreshock side. Our results indicate that the existence of a preparatory phase anticipating main shocks represents the most plausible explanation for the occurrence of foreshocks.
Reply to Comment by Zhao et al. on “Paleomagnetism of the Late Cretaceous Red Beds From the Far Western Lhasa Terrane: Inclination Discrepancy and Tectonic Implications”

In this manuscript, we checked all the pieces of evidence separately and conclude that the evidence Zhao et al. (2021, https://doi.org/10.1029/2020TC006520) provided cannot be regarded as arguments supporting their points. Our observations show that (i) sampling units and depositional environment support that the Jingzhushan Formation red beds could be affected by the syntectonic sedimentation, (ii) characteristic remanent magnetization directions observed from the Jingzhushan Formation red beds represent primary magnetization acquired during the syntectonic sedimentation, not secondary remagnetization due to strain reorientation of remanence, and (iii) inclination discrepancy of the Jingzhushan Formation red beds could be attributed to syntectonic sedimentation. Therefore, the paleomagnetic results obtained from the Jingzhushan Formation red beds are reliable for paleogeographic reconstructions.
Application of Acupressure in Reducing Pruritus Scale in Hemodialysis Patients

Pruritus is a common problem in patients with chronic kidney disease who undergo dialysis. It is characterized by an uncomfortable sensation that leads to scratching. Acupressure is a complementary method used to manage various symptoms and health problems, including pruritus. This study aims to identify the effect of acupressure at the LI-11 point in reducing pruritus in a hemodialysis patient. This study used pre-experimental research with preand post-test without control. This study occurs in a hemodialysis unit in Central Jakarta, Indonesia. The sample was comprised of 19 respondents in the hemodialysis unit who met the inclusion criteria and completed the study. Respondents received acupressure in the LI-11 point two times per week for four weeks for a total of eight sessions. Data were collected using individual characteristics questionnaire, pruritus characteristics, and Visual Analog Scale (VAS) for pruritus. The data analysis used was a dependent t-test. The majority of respondents were male with duration of hemodialysis 5 hours, mean of age 53 years, mean of length of HD is 53 months, mean of Hb level is 9.67 gr/dl, mean of urea level is 117.05 mg/dl, mean of creatinine is 10.26 mg/dl. The results indicate that acupressure has a significant effect in reducing of pruritus scale (p-value 0,000). This study recommends nurses to be able to use acupressure therapy to reduce the scale of pruritus experienced by hemodialysis patients.
Association of Mammographic Density Reduction with Hormone Therapy and Relapse in Asian Breast Cancer Patients: A Multivariate Survival Analysis

Purpose Currently, the ability to predict the development of resistance to hormone therapy (HT) in breast cancer patients is suboptimal, and attempts are ongoing to develop more specific prognostic markers for endocrine resistance. Several studies have shown that mammographic breast density is an important predictor of outcomes following adjuvant HT. This study aimed to evaluate HT-induced mammographic density (MD) reduction (MDR) and its association with relapse and metastasis in Taiwanese patients.MethodsIn this retrospective study conducted at the Changhua Christian Hospital, 1553 breast cancer patients were screened. Of these, 399 with luminal-like cancer who were first diagnosed between January 2011 and December 2017 and had received adjuvant HT (include treatment with tamoxifen, aromatase inhibitor or mixture) were enrolled. The mean follow-up period for all patients was 1847 days (median follow-up period was 1815 days). The MD was measured as a percentage using the automatic volumetric mammographic density estimation.ResultsWe found the MDR equally 20.8% which MD measured was before and after surgery and HT during 6 to 18 months was a significant cut-off threshold for good or pool diagnosis in breast cancer patients who receiving HT. By utilized the Cox proportion-hazards model analysis, the disease-free survival rate was significantly higher in MDR-positive patients (MDR > 20.8%) than in MDR-negative patients (MDR < 20.8%) (p = 0.048). Age, histologic grade, histologic stage, and lymph node metastasis showed a significant association with recurrence-free survival in all patients.ConclusionsOur results demonstrate the feasibility of using MDR to predict the preliminary outcomes of adjuvant HT in Asian breast cancer patients.
The Employees’ State of Mind during COVID-19: A Self-Determination Theory Perspective

The unprecedented outbreak of the Coronavirus (COVID-19) pandemic had a devastating effect on the global economy. Many businesses experienced a significant decline in their business activities. As a result, their employees were concerned on their job security and long-term employment prospects. This research explores the service employees’ motivations in their workplace environment and sheds light on their perceptions about their employers’ corporate social responsibility (CSR). The methodology integrated key measures from the self-determination theory (SDT), CSR, job security and organizational performance. A structural equations modelling (SEM-PLS3) approach was used to analyze the proposed research model. The findings confirmed that the employees’ intrinsic motivations were significantly predicting their organizational performance. Their identified motivations, job security as well as their employers’ social responsibility were significant antecedents of their intrinsic motivations. Moreover, there were significant indirect effects that predicted the employees’ productivity in their workplace during COVID-19.
Evaluation of the Multichambered Treatment Train, a Retrofit Water‐Quality Management Practice

This study evaluated the water‐quality benefits of a new urban best management practice design called the multichambered treatment train (MCTT). The study consisted of collecting flow‐weighted water‐quality samples at influent and effluent locations for 15 consecutive storms. Device efficiencies were based on load reductions of 68 constituents. Total rainfall amounts for the 15 storms ranged from 0.45 to 3.48 cm, yielding 1.7 to 8.9 m3 of water treated by the device. None of these storms surcharged the unit. High reduction efficiencies were found for all particulate‐associated constituents, such as total suspended solids (98%), total phosphorus (88%), and total recoverable zinc (91%). Dissolved fractions had substantial but somewhat lesser removal rates (dissolved phosphorus, 78%; dissolved zinc, 68%). Total dissolved solids, which originated from road salt storage, yielded 4 times the total suspended solids load. No appreciable shift was seen between influent and effluent particle size distributions.
