Published: August 2022

Aim: Avian Influenza (AI) is a zoonotic disease that causes death in poultry and humans. Monitoring the virus needs to be carried out continuously to prevent outbreaks of the disease. Seroprevalence and detection of H5N1 and H9N2 AI virus antigen were intended to monitor the presence of viruses in local chickens in Tabanan, a Regency of the Indonesian island Province of Bali. The research aims were to detect the presence of H5N1 AI virus, and to know the distribution of this virus in Tabanan Regency. Materials and Methods: Research located in six districts of Tabanan regency namely Baturiti, Penebel, Marga, Kediri, Tabanan, and Kerambitan. A total of 1,398 local chickens that never been vaccinated with AI were randomly sampled in this study. The samples collected were serum, cloacal and tracheal swabs. Serum samples were tested with hemagglutination inhibition (HI) assay. While samples of cloacal and tracheal swabs were isolated in 9-day-old germinated chicken eggs, followed by hemagglutination assay and RT-PCR test using H5N1 and H9N2 primers. Results: AI seroprevalence in local chickens in Tabanan Regency was 1% with the distribution in each district as follows; Penebel 1.6%, Kerambitan 1.2%, Marga 1%, while Tabanan, Kediri, and Baturiti 0.7% each. H5N1 AI virus was detected in 11 samples,  i.e. five in Marga district and three in Penebel district, two in Kediri, and one in Tabanan, while the H9N2 AI virus was not detected. Conclusion: These results indicate that H5N1 AI virus may still circulate in local chickens in Tabanan Regency, Bali.

This study aims to examine the effect of profitability, dividend policy, firm size, and capital structure variables on enterprise value in Indonesia Stock Exchange- or IDX-listed companies for 2011-2015 period. The population in this study were 37 IDX-listed companies for 2011-2015 period. 12 companies were sampled purposively. The data were analyzed using multiple regression. The results show that probability, dividend policy, firm size and capital structure simultaneously have an effect on enterprise value. Partially, profitability and dividend policy have a significant positive effect on enterprise value, capital structure has a significant negative effect on enterprise value, and firm size has a negative, yet statistically insignificant effect. From the results of this study, it is expected that any company management pays attention to their profitability, dividend policy, and capital structure as these factors have a significant effect on enterprise value and thus they need to be maximized to make the enterprise value greater.

Favipiravir is a synthetic prodrug, first discovered while assessing the antiviral activity of chemical agents active against the influenza virus. The present study is aimed at developing and validating a new colorimetric methods for its determination in both pure form and in tablet formulation. The developed method utilizes ion-pair spectrophotometry and is employed for the quantitative evaluation of the drug using the acidic dyes - methyl orange (MO) and methyl red (MR) as ion-pairing agent. The ion-pair complex of drugs with both dyes obeyed Beer’s law in the range of 10 -50 µg/ml with a acceptable correlation coefficients. Recovery by the method was also good, with a relative standard deviation (%RSD) less than 2.5%. The developed method was successfully applied to determine favipiravir in tablet formulation and was demonstrated to be accurate, precise and reproducible. It is also sufficiently sensitive and specific for the determination of the drug in bulk and formulation with satisfactory results.

Liberalisation of Banking Services Under the Framework of Asean Economic Community: an Indonesian Perspective
Authors: Nandang Sutrisno  , Mahardhika Nur Gemilang
Published: August 2022

Among the ASEAN members, compared to other members, Indonesia is relatively more liberal in opening up international trade in financial services, especially in banking sector. Through its submission of CIO to the WTO in 2005, Indonesia to some degree offered   certain liberalization of banking sector, together with some other services governed under the GATS. On the other hand, other members of ASEAN show their carefulness in liberalizing their banking sectors.  As consequence, on one hand foreign banks have occupied nearly 50% of the Indonesian banking industry, and there are only a few units from Indonesia’s domestic banks that present in its ASEAN neighbours, on the other hand. Using normative method, this research elaborates on how Indonesia should strike a balanced stand between its over-liberalized banking sector and the reluctance of other members, while maintaining the GATS principle of “progressive development.”  The authors concludes that one of the ways for Indonesia to flip the odds to be in its favour is by urging the implementation of the reciprocity principle in banking services in ASEAN, which additionally, will also stimulate the liberalisation schedule of the latter.

Published: August 2022

The project trained forest managers from Kesatuan Pengelolaan Hutan (KPH) and Social Forestry units in Aceh Province in forest resource data collection and the use of three tools that report important forest ecosystem services. Data were collected in systematic forest plots by local KPH staff and social forestry community members for measuring forest carbon, tree biodiversity and forest ecosystem health. Teams represented nine different forest ecosystems in Aceh Province, Indonesia. Average forest carbon estimates range from a low of 27.14 Mg C ha-1 in a coffee agroforestry system to a high of 446.93 Mg C ha-1 in a tropical forest area managed under social forestry. Tree biodiversity ranged from a low of one species as expected in a coastal mangrove forest to a high of 35 species in the tropical forest area managed under social forestry. Forest health conditions on average for the nine areas were mostly healthy, with a few noted in fair condition and one considered to be in poor condition. Resources provided at the local level would enable mainstreaming of field data collection for measuring these forest ecosystem services, and continued and expanded training should be considered to meet national demand.

Authors: Gubernatorova V. , Kuznetsova T. , Semenov B.
Published: August 2022

Purpose: This work is based on a study of the features of keeping young cattle (organization of livestock placement, feeding regimen, veterinary manipulations) in a breeding plant in the Leningrad Region, assessing these features and identifying their impact on the state of the livestock and animal productivity.

2000 heads of cattle, of which 915 are part of the dairy herd with average daily milk yield per cow - 19-20 kg (when cows are milked 2 times a day, freshly calved - 3 times) and the mass fraction of fat is 3.7%. After birth, calves are kept in a dispensary for up to 20 days, tied at a distance of 1.5-2 m from each other. After 20 days, the calves are transferred to group cages, 7 heads each, with a gradual change in feeding regimen. After 25 days, they are transferred to the calf house. The most common diseases in young animals are bronchopneumonia, pulmonary enphysema and dyspepsia. To prevent the development of infectious diseases in calves, vaccination is carried out from the age of 14 days. Against parainfluenza-3 and pasteurellosis vaccines Bovilis IBR (live labeled vaccine for specific prophylaxis against infectious bovine rhinotracheitis) and Bovilis Bovipast RSP vaccine (inactivated vaccine against parainfluenza-3 , respiratory syncytial infection and pasteurellosis of cattle) are used at a dose of 5 ml subcutaneously. At the age of three weeks, calves are vaccinated against salmonellosis (paratyphoid) and parainfluenza (again - after 10 days). After 2 weeks, calves are vaccinated against leptospirosis (repeat - after six months). From the age of two months they are vaccinated against tuberculosis. From the age of three months - against brucellosis, anthrax (revaccination after six months), depriving and rabies. At 3 months, the first deworming is carried out. Vaccination can increase the survival rate of young animals up to 97%. The ongoing activities are the main ones for the further use of breeding and commercial animals, the realization of their genetic potential and the production of high-quality products.

Authors: Wen Caihe , Zhang Yuan , Xia Xinru , Ma Xiang , Mao Yundong , Wang Dao Wu , Liu Jiayin
Published: August 2022

Background: With the prevalence of assisted reproductive technology (ART), the incidence of ectopic pregnancy (EP) is increasing, especially in patients with salpingectomy or proximal tubal occlusion. Methods: A total of 11,609 women who were undergoing ART and had undergone salpingectomy or proximal tubal occlusion, and 5388 women who achieved a clinical pregnancy were included in the study. Statistical analysis was used to determine whether the number of embryos transferred was associated with EP. Results: Both the number of embryos transferred and the day of embryo transfer differed significantly between those with and without EP (p < 0.05), while the number of embryos transferred was associated with interstitial pregnancy (IP) (p < 0.05) in those undergoing frozen-thawed embryo transfer (ET) cycles. Following multivariate modeling, the odds of having an EP in women undergoing frozen-thawed ET cycles increased with the number of embryos transferred (odds ratio [OR] 2.003, 95% confidence interval [95% CI] 1.036–3.876). Conclusions: The embryo transfer number was considered a risk factor for EP in patients undergoing frozen-thawed ET who had undergone salpingectomy or proximal tubal occlusion.
PROBLEMS OF DRINKING WATER SUPPLY IN SMALL SETTLEMENTS OF THE SOUTHERN URALS AND THE CIS-URALS
Authors: Abdrakhmanov Rafil Fazilovich , Poleva Aleksandra Olegovna
Published: August 2022

The article discusses the issue of water supply sources for small settlements located on the territory of the Southern Urals and the Cis-Urals. Based on almost 30 years of monitoring of a well used for the water supply of a summer country house, it is shown that the trend of the groundwater level in this area tends to decrease. At the same time, observations of chemical composition of water revealed an increase in the amount of nitrates. It has been established that the level of groundwater depends on the amount of precipitation. Their amount also affects the level of nitrates in groundwater. With an increase in precipitation, the amount of nitrates decreases. The problems shown indicate the need to control the quality of water used for non-centralized water supply of small settlements.
MINERALOGICAL FEATURES AND SUBSOLIDUS STRUCTURES OF IZRANDITES FROM ALEXANDROVSK COMPLEX
Authors: Saveliev Dmitry Evgenievich , Masagutov Rim Khakimovich , Sirota Sergey Nikolaevich
Published: August 2022

This article presents the results of studying the compositions of rock-forming and accessory ultramafic minerals of izrandite samples from Alexandrovsk metamorphic complex. It was found that petrographical, mineralogical and compositional features indicate igneous cumulative origin of studied rocks but amazing freshness of izrandite contradict with their “oldest age”. Together with igneous, numerous occurrences of subsolidus structures were found in studied rocks. These are following: reaction rims on the olivine-plagioclase boundaries, orthopyroxene-pargasite symplectite intergrowths on the olivine-augite and olivine-plagioclase boundaries, ilmenite and Ti-magnetite lamellae in clinopyroxene and amphibole grains, Ti-magnetite solid-solution breakdown structures. It is shown that spinel group mineral grains have complex structure including different blocks: Ti-magnetite with ilmenite exsolution lamellae, homogenous ilmenite and high-Al spinel, and these were probably formed by subsolidus processes. We have considered critically some scenarios of izrandite origin. We infer that izrandites are similar to cumulative rocks from some cratonic layered intrusions, but it is necessary to note that there is no hard evidence of that izrandite is relict of the oldest protolith of metamorphic rocks.
NEW DATA ON PYROCLASTICS IN THE ILTIBANOVO FORMATION (THE LOWER DEVONIAN OF THE WEST MAGNITOGORSK ZONE OF THE SOUTHERN URALS)
Authors: Fazliakhmetov Alexander
Published: August 2022

The subject of research is the petrography of sandstones and siltstones laminae 2–12 mm thick, occurring among the cherts in the lower part of the Iltibanovo Formation. 7 samples taken from the northern and southern ends of the dam of the Iltibanovsky reservoir in the Uchalinsky district of the Republic of Bashkortostan were studied.

The petrographic study of the laminae showed that they contain euhedral crystals and angular fragments of pyroxenes and plagioclases; thin elongated plagioclase crystals; shapeless pyroclasts composed of chlorite or felsite mass, which were originally fragments of volcanic glass. These findings indicate synsedimentary (Lochkovian or Silurian) explosive volcanism.
GENESIS OF NEPTUNIAN DIKES IN THE STERLITAMAK SHIKHANS
Authors: Gorozhanin Valery Michailovich , Gorozhanina Elena Nickolaevna
Published: August 2022

A review of the existing ideas about the prevalence, morphology and genesis of neptunian dikes cutting through carbonate reef Lower Permian massifs showed ambiguity in the interpretation of their genesis – they were considered as consedimentary interbiohermic cavities, interlayers associated with periodic flooding of reefs, as well as filling tectonic cracks. New data obtained during field observations on the Toratau, Yuraktau massifs and in the Shakhtau quarry allowed us to establish a large morphological diversity of neptunian dikes and conclude that in the formation of some bodies it is possible to distinguish in their gevelopment the stages of calm and active (catastrophic) sedimentation. The latter was accompanied by the formation of underwater landslide folds, crushing breccias and collapse structures of large blocks of reef rocks. Deep parts of tectonic clefts on the Yuraktau, where the material of the overlapping deposits could not reach, was «healed» by radially radiant aggregates of calcite crystals.
Neptunic dikes are indicators of seismic impact on the reef zone in the western side of the Pre-Uralian foredeep and reflect the influence of the Early Permian collision and the growth of the Ural Mountains on the adjacent part of the East European Platform. Outcrops of tubifite biogerms of Asselian age were found in the southern part of the Pre-Uralian foredeep. A modern analogue of this process can be the landslide of large blocks of rocks in the area of the Great Barrier Reef of Australia, discovered by underwater multibeam equipment.
PHYSICAL AND CHEMICAL CONDITIONS FOR THE FORMATION OF THE ORLOVKA OROGENIC GOLD DEPOSIT IN THE SOUTHERN URALS (ACCORDING TO THE DATA OF A CHLORITE
GEOTHERMOMETER AND REE DISTRIBUTION IN CALCITE)
Authors: Znamensky Sergei Evgenievich , Znamenskaya Nina Michailovna
Published: August 2022

The chemical composition of chlorite from ore-bearing albite-biotite-quartz-chlorite-epidote-actinolite schists and the REE content in calcite of sulfide-carbonate-quartz veinlet ores of the Orlovsky orogenic gold deposit located in the zone of the Main Ural Fault in the Southern Urals have been studied. The chemical composition of chlorite was determined on a Tescan Vega Compact scanning electron microscope with an Oxford Instruments Xplorer 15 energy-dispersive analyzer. The REE content in calcite was studied using inductively coupled plasma mass spectrometry (ICP-MS) on a PerkinElmer ELAN 9000 instrument. It has been established that chlorite, represented by a variety with a transitional chemical composition from clinochlore to pycnochlorite (5.78–6.0 Si f.u.; 0.27–0.28 Fetot/(Fetot + Mg)) was formed at a temperature of 295.6–266.2°C. The REE distribution spectra in calcite, normalized to C1 chondrite, are characterized by the accumulation of light lanthanides ((La/Yb)N=1.28–7.18), the value of the ratio (La/Lu)N=1.1–6.58, indicating the predominance of rare earth sorption processes in the fluid, small negative anomalies of cerium (Ce/Ce*=0.71–0.92) and positive anomalies of europium (Eu/Eu*=1.05–2.38). Negative Ce anomalies in calcite may be due to the interaction of the fluid with limestones, as well as the presence of meteoric water in its composition in a small amount. Positive Eu anomalies indicate low-temperature conditions for calcite crystallization (<250°С). A model of deposit formation is proposed, which provides for the generation of mineral-forming fluid at the progressive stage of greenschist dynamometamorphism of host rocks and the formation of calcite and gold-bearing mineralization at the regressive stage. Data on REE geochemistry confirm the hydrothermal-metamorphogenic genesis of the gold-bearing sulfide-carbonate-quartz mineralization of the Orlovsky deposit. Keywords: Southern Urals, orogenic gold deposit, chlorite geothermometer, REE distribution, europium anomaly.
Post-colonial Nation and and Cultural Hegemony in George Orwell’s Animal Farm A Rereading
Authors: Salma Umme
Published: August 2022

Animal Farm by George Orwell is an English literary classic. The novel is taught and read in most English departments worldwide to introduce beginners to English literature. It has been widely read and researched as an allegorical satire, focusing chiefly on communist Russia. Specifically, this 1945 novel is an excellent referent for any state-level abuse of power. Researchers also read the novel’ representations of the dominants’ corruption and the marginal’s misery from a post-colonial perspective. The present paper builds on the post-colonial research tradition. However, it turns the interpretative screw a little, employing a cultural lens. The paper reads the novel as an allegory of a post-colonial nation that dismantles the imperial powers but becomes destabilised under the sway of cultural hegemony. It divides animal time through the colonial/post-colonial binary. It explores how the colonial time enforces cultural authenticity and why post-colonial times dislocate it. The paper situates the study within colonialism, nation and cultural hegemony framework. In this way, the article uncovers various power axes in society and contends that the post-national period becomes unstable when various forms of cultural hegemony render people from transcultural to ambivalent.

A Mixed Effects Changepoint Quantile Regression Model for Longitudinal Data
Authors: Gad Ahmed , Ibrahim Wafaa I. M. , Abdrabou Abdelnaser S.
Published: August 2022

 The longitudinal individual response profiles could exhibit a mixture of two or more phases of increase or decrease in trend throughout the follow up period, with one or more unknown transition points usually referred to as breakpoints or change points. The existence of such unknown point disturbs the sample characteristics, so the detection and estimation of these points is crucial. Most of the proposed statistical methods in literature, for detecting and estimating change points, assume distributional assumption that may not hold. A good alternative in this case is to use a robust approach which is the quantile regression model. There are trials in the literature to deal with quantile regression models with a change point. These trials ignore the within subject dependence of longitudinal data. In this paper we propose a mixed effect quantile regression model with a change point to account for dependence structure in the longitudinal data. Fixed effect parameters, in addition to the location of the change point, are estimated using profile estimation method. The stochastic approximation EM algorithm is proposed to estimate the fixed effect parameters exploiting the link between asymptotic Laplace distribution and the quantile regression. In addition, the location of the change point is estimated using the usual optimization methods. A simulation study shows that the proposed estimation and inferential procedures perform reasonably well in finite samples. The practical use of the proposed model is illustrated using a COVID-19 data. The data focus on the effect of global economic and health factors on the monthly death rate due to COVID-19 during from the 1st of April 2020 till the 31st of April 2021. 
Comprehensive study of good model training for prostate segmentation in volumetric MRI
Authors: Nácher Carlos
Published: August 2022

Prostate cancer was the third most common cancer in 2020 internationally, coming after breastcancer and lung cancer. Furthermore, in recent years prostate cancer has shown an increasingtrend. According to clinical experience, if this problem is detected and treated early, there canbe a high chance of survival for the patient. One task that helps diagnose prostate cancer isprostate segmentation from magnetic resonance imaging. Manual segmentation performed byclinical experts has its drawbacks such as: the high time and concentration required from observers;and inter- and intra-observer variability. This is why in recent years automatic approaches tosegment a prostate based on convolutional neural networks have emerged. Many of them havenovel proposed architectures. In this paper I make an exhaustive study of several deep learningmodels by adjusting them to the task of prostate prediction. I do not use novel architectures, butfocus my work more on how to train the networks. My approach is based on a ResNext101 3Dencoder and a Unet3D decoder. I provide a study of the importance of resolutions in resamplingdata, something that no one else has done before.

Pythagorean triple $ a^{^2}+b^{2}=c^{2} $ are known from ancient Sumerian. A well known formula by Euclid $a^{2}+b^{2}=(m^{2}-n^{2})^{2}+(2mn)^{2}=m^{2}+n^{2})^{2}=c^{2}$ can generate all Pythagorean triples. In this paper, another simple formula can generate not only positive integers but any positive Real number with preservation of variable “a” also from variable “a” the triples will be found. the formula is $c^{2}=a^{2}+(\frac{a^{2}}{2m}-\frac{m}{2})^2$ $\forall m \in \mathbb{R}$ where $m=c-b$.
Technology acceptance and trust: Overlooked considerations in young people’s use of digital mental health interventions
Authors: Sawrikar Vilas , Mote Kellie
Published: August 2022

Objectives: Digital mental health interventions (DMHIs) have potential to provide support at scale for young people, yet uptake is low. The present study investigated whether attitudes towards technology solutions in relation to perceived usefulness, perceived ease of use, and trust of DMHIs influenced young people’s intentions to use DMHIs. Methods: Young people aged 17–25 (N = 248) were recruited online via advertising (e.g., Facebook, Twitter) to a survey assessing attitudes of technology acceptance and intentions to use DMHIs, previous use of DMHIs, demographics, and mental health need. Results: Participants reported relatively neutral attitudes towards DMHIs. Outcomes from linear regression indicated that greater perceived usefulness (β = .24) and trust of DMHIs (β = .28) have significant small to moderate positive associations with higher intentions to use DMHIs. Perceived ease of use (β = .07) was not associated with intentions to use DMHIs. Gender, age, previous use of DMHIs, and mental health need did not moderate unique associations between intentions to use DMHIs and perceived usefulness, perceived ease of use, and trust of DMHIs. Conclusions: Moderate levels of technology acceptance for mental health, particularly in domains of perceived usefulness and trust of DMHIs, may represent a barrier to DMHI adoption among young people. Developers and service providers are recommended to provide information about the usefulness, effectiveness, and trustworthiness of DMHIs to improve uptake among young people.
Anger, evidence, & trending opinions: we trust consensus when we believe it reflects genuine persuasion
Authors: Richardson Emory , Keil Frank
Published: August 2022

Social learners frequently treat the consensus judgment of multiple informants as evidence favoring one option over another. However, in populations of social learners, learners’ informants are also learning from each other, making consensus a product of complex informational dependencies between informant. These interdependencies can make consensus more accurate when informants are reliably able to identify accurate testimony, or less accurate when they are not. But do learners consider whether their sources are reliable judges of each others’ testimony when deciding whether to trust their consensus judgment? Here, participants in four experiments rated their confidence in a consensus judgment, and then saw that consensus change when one faction “converted” informants from an opposing faction during a meeting (e.g., consensus grew from 6v4 to 9v1 or falls from 9v1 to 6v4), and again rated their confidence. Critically, we manipulate affective cues during the meeting: the focal faction attempts to convert the opposing faction either by shouting angrily at them or expressing surprise. We find an asymmetric effect of affective cues on trust in consensus: while confidence in the judgment of surprised factions rises or falls as they gain or lose endorsers, confidence in angry factions falls when they lose endorsers, but does not rise even when they gain endorsers. Results suggest that people’s trust in non-independent consensus may depend on assumptions about the nature of informational dependencies between informants.
Testing the automaticity features of the Affect Misattribution Procedure: The roles of awareness and intentionality

Published: August 2022

The Affect Misattribution Procedure (AMP) is a measure of implicit evaluations, designed to index the automatic retrieval of evaluative knowledge. The AMP effect consists in participants evaluating neutral target stimuli positively when preceded by positive primes and negatively when preceded by negative primes. After multiple prior tests of intentionality, Hughes et al. (2023) examined the role of awareness in the AMP and found that AMP effects were larger when participants indicated that their response was influenced by the prime than when they did not. Here we report seven experiments (six preregistered; N = 2,350) in which we vary methodological features of the AMP to better understand this awareness effect. In Experiments 1–4, we establish variability in the magnitude of the awareness effect in response to variations in the AMP procedure. By introducing further modifications to the AMP procedure, Experiments 5–7 suggest an alternative explanation of the awareness effect, namely that awareness can be the outcome, rather than the cause, of evaluative congruency between primes and responses: Awareness effects emerged even when awareness could not have contributed to AMP effects, including when participants judged influence awareness for third parties or primes were presented post-hoc. Finally, increasing evaluative strength of the primes increased participants’ tendency to misattribute AMP effects to the influence of target stimuli. Together, the present findings suggest that AMP effects can create awareness effects rather than vice versa and support the AMP’s construct validity as a measure of unintentional evaluations of which participants are also potentially unaware.
A formal model of interpersonality
Authors: Westermann Stefan , Banisch Sven
Published: August 2022

Capturing the complexity of interpersonal dynamics – emerging from the approach and avoidance motivation of two individuals in dyadic interplay that unfolds simultaneously on multiple time scales in order to satisfy their psychological needs – remains a scientific challenge. In line with calls for embracing complexity in psychological research using formal modeling, the purpose of this mathematical, non-data-driven (and thus not preregistered) study is to investigate the underlying mechanisms of the formation and maintenance of interpersonal relationships using evolutionary game theory. After formalizing interpersonal situations based on the affiliative motives of their interactants, a relational state space is constructed that reflects the ways of relating available to the interactants in the momentary state of their interpersonal relationship. This allows for modeling the evolution of an interpersonal relationship as a trajectory – driven by positive and negative reinforcement – in the relational space. Depending on the motives of both interactants, three qualitatively different interpersonal dynamics emerge: (1) global stability with only one relational attractor (e.g., an interpersonal relationship of pure friendliness in the long run), (2) bistability with two mutually exclusive relational attractors (e.g., either pure friendliness or pure distance), and (3) cyclicality with periodic orbits in the relational space (e.g., oscillation between friendliness and distance). Grounded in empirically supported psychological constructs, the formal model generates the well-known pattern of interpersonal complementarity. Over and above, novel interpersonal patterns emerged that might point to some underlying mechanisms of the interpersonal maintenance of psychopathology. The numerous model limitations as well as avenues for empirical tests and further development are discussed.

Self-critical perfectionism and anxiety sensitivity are potential vulnerability factors for increased distress following performance failure. We hypothesized that participants who fail a statistics quiz will have lower state self-esteem, lower positive affect, and greater negative affect at post-test than those who get a good grade, after controlling for pre-test scores and the effect of experimental condition would become larger as self-critical perfectionism and anxiety sensitivity increase. Exploratory analyses examined rigid perfectionism and a newly introduced construct (statistics anxiety sensitivity) as moderators. We tested this vulnerability-stress model in 329 post-secondary students using a two-group, pre-post, between-subjects design. Students completed an easy or hard statistics test and were assessed on pre- and post-test state self-esteem (social & performance) and state affect (anxiety, dysphoria, hostility, & positive affect). Across outcomes, main effects of experimental condition predicted between 7-33% of the variance, with the largest effects for performance self-esteem. Personality by condition interactions predicted 0.1-2% of the variance; 16 of 24 interactions were statistically significant in the expected direction (i.e., the effect of experimental condition was larger for participants high in measured personality traits). Findings suggest personality traits are vulnerability factors for decreased self-esteem and increased negative affect following failure in a statistics assessment.
The Hidden Curriculum of Academic Writing: Toward Demystifying Manuscript Preparation in Counseling Psychology

Published: August 2022

In this article, we aim to unpack some of the hidden curriculum in publishing successfully in the Journal of Counseling Psychology (JCP) and other academic outlets. The many unspoken and implicit considerations behind writing a successful academic article can reinforce epistemic exclusions around class, gender, race, sexuality and other axes of power that ultimately limit who gets to publish in academic journals and about what. Thus, we work to articulate the processes behind writing an academic article. Specifically, we offer suggestions for (a) writing compelling, precise, and parsimonious introductions, (b) clearly addressing the goals of the study via an accurate and detailed description of the method, (c) aligning analytic decisions with the research questions or hypotheses and the data parameters at hand, and (d) discussing the story of data in the context of prior scholarship, study limitations, and real-world implications. Where applicable, we provide concrete examples of published studies to “unhide” writing processes and to illustrate the invisible narratives and intentions behind key writing practices. We also present a checklist as an easy-to-reference companion to this article to help demystify the writing process. This article aligns with the commitment of JCP’s editorial leadership to play an active role in opening up the scholarly publication process so that the pipeline of manuscripts submitted to and accepted by JCP shapes a more inclusive future for the field.
Wealth and Its Distribution in Germany, 1895–2018

Published: August 2022

German history over the past 125 years has been turbulent. Marked by two world wars, revolutions and major regime changes, as well as a hyperinflation and three currency reforms, expropriations and territorial divisions, it provides unique insights into the role of country-specific shocks in shaping long-run wealth dynamics. This paper presents the first comprehensive study of wealth and its distribution in Germany since the 19th century. We combine tax and archival data, household surveys, historical national accounts, and rich lists to analyze the evolution of the German wealth distribution over the long run. We show that the top 1% wealth share has fallen by half, from close to 50% in 1895 to 27% today. Nearly all of this decline was the result of changes that occurred between 1914 and 1952. The interwar period and the wealth taxation in the aftermath of World War II stand out as the great equalizers in 20th century German history. After unification in 1990, two trends have left their mark on the German wealth distribution. Households at the top made substantial capital gains from rising business wealth while the middle-class had large capital gains in the housing market. The wealth share of the bottom 50% halved since 1990. Our findings speak to the importance of historical shocks to the distribution and valuations of existing wealth in explaining the evolution of the wealth distribution over the long run.
