Characterizing post-traumatic growth in individuals with traumatic brain injury according to social participation, self-awareness, and self-identity.

After traumatic brain injury (TBI), individuals may face challenges in their social participation, self-awareness, and self-identity. However, positive life changes can also be experienced (i.e., post-traumatic growth). This study aimed to characterize the social participation, self-awareness, and self-identity of individuals with TBI displaying post-traumatic growth. Fifteen participants (male = 10, mean age = 49.7 years) with moderate to severe TBI (average years post-injury = 15.2) were included in this mixed-methods study. Self-report questionnaires were used to assess social participation, self-awareness, and self-identity. Qualitative data, collected using semi-structured interviews, were used to categorize participants into two groups: higher (n = 8) and lower (n = 7) post-traumatic growth. Descriptive statistics were used to characterize participants in each group in terms of their social participation, self-awareness, and self-identity. Participants with higher post-traumatic growth had increased social participation, higher self-awareness, and fewer negative discrepancies between their pre- and post-injury self-identities, compared to participants with lower post-traumatic growth. This study contributes to a more comprehensive understanding of post-traumatic growth through the use of both qualitative and quantitative data. These findings can inform future research and development of programs to promote post-traumatic growth post-TBI.

Curse or blessing? Impact of the scope and duration of negative attainment discrepancy on ESG practices

AbstractToday, scholarly discourse has been primarily centered around the causes and consequences of enterprise environmental, social, and governance (ESG) practices. However, given that enterprises may encounter negative attainment discrepancies across several areas (scope) and endure negative discrepancies over an extended period of time (duration), the question of whether and how negative attainment discrepancy affects enterprise ESG practices remains unexplored. Based on the behavioral theory of the firm, this study explores the differentiated impact of the scope and duration of negative attainment discrepancies on enterprise ESG practices, using Chinese A‐share listed companies (data from 2011 to 2019) as the research sample. Meanwhile, it investigates the moderating effect of multidimensional human capital in Top Management Teams (TMT) from technical background, overseas experience, and educational attainment. The results demonstrated that the scope of negative attainment discrepancy promotes enterprise ESG practice, while the duration of negative attainment discrepancy inhibits ESG practice. Furthermore, the TMT's technical background, overseas experience, and educational attainment strengthen the scope of negative attainment discrepancies in promoting enterprise ESG practice. Additionally, the overseas experience of the TMT reinforces the inhibitory impact of the duration of negative attainment discrepancies on enterprise ESG. The results of this study can provide the corresponding decision‐making suggestions and references for the senior management team and shareholders of enterprises.

Associations and discrepancies between global self-ratings of oral health and general health: a Bayesian approach.

To estimate the discrepancies between global ratings of oral health and general health and investigate the factors associated with self-rated oral health (SROH) and self-rated general health (SRGH). Data were collected from 502 participants aged 18 to 81 years. A structured questionnaire was used to obtain data regarding sociodemographic characteristics and self-reported conditions. Global self-ratings of oral health and general health were the main outcomes. Discrepancies between self-ratings of oral health and general health were stratified by independent variables. Bayesian ordinal logistic regression models were fitted to estimate the posterior distributions of parameters and 95% credible intervals (95% CrI). The proportion of participants who rated their oral health worse than general health was 28.6% (95% CrI: 24.7-32.3). Negative discrepancies between SROH and SRGH were associated with being men, reporting gingivitis, and lower income. Sex (95% CrI: 1.12-2.25) impacted only on SRGH. Income (SROH - 95% CrI: 1.52-6.40; SRGH - 95% CrI: 1.08-4.56), tertiary education (SROH - 95% CrI: 1.13-2.53; SRGH - 95% CrI: 1.01-2.32), self-reported missing teeth (SROH - 95% CrI: 1.57-3.46; SRGH - 95% CrI: 2.21-4.92), self-reported gingivitis (SROH - 95% CrI: 1.10-2.40; SRGH - 95% CrI: 1.71-3.82), and self-reported chronic health problem (SROH - 95% CrI: 1.38-3.08; SRGH - 95% CrI: 1.61-3.59) impacted on both outcomes. Substantial discrepancies between self-rated oral health and self-rated general health were found and were associated with being male, reporting gingivitis, and having lower income.

Affective Responses to Fitness Testing in College-Aged Women

Physical inactivity is common among women and a quarter of college-aged women are classified as overweight or obese, making this population an important target for obesity prevention. Fitness testing is commonplace, and practitioners can hold an underlying belief that discrepancies will promote positive responses. However, little research has examined the affective responses to fitness testing in adults. The purpose of this study was to assess the affective responses to common fitness testing, while examining relationships to physical self to help elucidate why some respond to such testing and others do not. Forty-eight college-aged women were presented with their discrepancy from a normative standard across six fitness tests. Findings support previous conceptualizations on discrepancies and affective responses, in that greater negative discrepancies from normative standards were associated with greater changes in negative feeling states. In addition, the results suggest that only certain discrepancies pose a threat to perceived satisfaction with one’s physical self (i.e., self-concept)—mainly though subdomains related to body appearance and aerobic fitness. In other words, the greater the perceived satisfaction of self, the greater negative emotional response was experienced to the specific test discrepancy. The notation of “threats” to important domains of self-concept might help explain why fitness testing that alerts individuals where they are discrepant produce behavioral changes in some but not others. Professionals should consider the impact of providing fitness test discrepancies on negative affective responses, with the possible impact on motivation and future behavior choices to reduce the discrepancy.

Characterising Posttraumatic Growth in Individuals With TBI Based on Social Participation, Self-Awareness, and Self-Identity

<h3>Research Objectives</h3> To characterise individuals with higher and lower posttraumatic growth based on their social participation, self-awareness, and self-identity. <h3>Design</h3> A sequential explanatory/exploratory mixed-methods design. <h3>Setting</h3> General community in British Columbia. <h3>Participants</h3> 15 participants with moderate to severe TBI (average age=49.7, male=10, average years post-injury= 15.2). <h3>Interventions</h3> Not applicable. <h3>Main Outcome Measures</h3> Qualitative data were collected through semi-structured interviews (approximately 40 minutes). Quantitative data were obtained from self-report questionnaires that assessed social participation (Impact of Participation and Autonomy), self-awareness (Awareness Questionnaire), self-identity (Head Injury Semantic Differential Scale-III), and global functioning (Mayo-Portland Adaptability Inventory-4). For the analysis, qualitative data were used to categorise participants into two groups of higher (n=8) and lower (n=7) posttraumatic growth. The quantitative data were then used to characterise the participants. <h3>Results</h3> Participants with higher posttraumatic growth had more social participation, higher self-awareness, and fewer negative discrepancies in their pre- and post-injury identities. Participants with lower posttraumatic growth had less social participation, lower self-awareness, and more negative discrepancies in pre- and post-injury identities. <h3>Conclusions</h3> This study contributes to the growing literature of posttraumatic growth after TBI by describing the characteristics of participants with higher and lower levels of posttraumatic growth. By integrating qualitative and quantitative data, this study provides a more comprehensive understanding about the subsequent growth that may take place after a TBI. Findings can facilitate future experimental studies to explore the relationships between posttraumatic growth and social participation, self-awareness, and self-identity in individuals with TBI. <h3>Author(s) Disclosures</h3> There are no author disclosures.

The Effect of Cognitive Dissonance Caused by eSports Users’ eWOM Information Provision on Self-Rationalization and Recommendation Intention: Focusing on e-Sports Users in Korea and Japan

Purpose: EWOM is an important variable that affects the selection and purchase process of users who enjoy e-sports, and this is likely to lead to other users’ willingness to recommend. However, e-sports users do not always have positive and satisfactory experiences through eWOM. Sometimes you experience dissatisfaction with your choice through eWOM, and you can see that you take various actions to resolve complaints after purchasing to remove uncomfortable feelings. Therefore, this study aims to analyze the effect of cognitive dissonance according to eWOM for users who enjoy e-sports and to examine the structural relationship of e-sports recommendation intention through self-rationalization of users who have experienced cognitive dissonance. Research design, data, and methodology: To verify this research model, an online survey was conducted using structured questionnaires for users from both Korea and Japan who have used e-sports within the last three months. Of a total of 180 questionnaires, 160 copies were used for the final analysis, excluding 20 copies with many unfaithful responses or poor internal consistency. After that, through the process of data coding, the SPSS18 program and the AMOS21 analysis program were used to demonstrate the researched and designed structural equation model. Implications: Summarizing the results of this study, eWOM had a positive (+) effect on both positive and negative inconsistencies in cognitive dissonance. Positive inconsistency was found to have a positive effect on recommendation intention. Negative discrepancies were found to have an effect on self-rationalization, but self-rationalization was found to have no effect on recommendation intention. Finally, it was found that there was a difference between eWOM and e-sports users in Korea and Japan in the structural relationship between cognitive dissonance, selfrationalization, and recommendation intention.

Effects of the Alpha, Beta, and Gamma Binaural Beat Brain Stimulation and Short-Term Training on Simultaneously Assessed Visuospatial and Verbal Working Memories, Signal Detection Measures, Response Times, and Intrasubject Response Time Variabilities: A Within-Subject Randomized Placebo-Controlled Clinical Trial.

Introduction Binaural beats (BBs) are phantom sound illusions perceived when two sounds of slightly different frequencies are separately transmitted to the ears. It is suggested that some BB frequencies might entrain the brain and enhance certain cognitive functions such as working memory or attention. Nevertheless, studies in this regard are very scarce, quite controversial, and merely covering a very small portion of this vast field of research (e.g., testing only a few BB frequencies), not to mention adopting some limited methodologies (e.g., no assessment of the loudness of the BB sound, adopting only between-subject analyses, and testing only one perceptual modality). Hence, we aimed to assess the potential effects of alpha, beta, and gamma BBs on cognitive-behavioral parameters of working memory and attention examined simultaneously in two different modalities (visuospatial and auditory-verbal). Methods This within-subject five-arm randomized placebo-controlled clinical trial included 155 trials in 31 healthy right-handed subjects (17 women, 14 men, 30.84 ± 6.16 years old). Each subject listened to 8-minute sessions of 10 Hz, 16 Hz, and 40 Hz binaural beats versus 240 Hz pure tone and silence (in random orders). In each 8-minute block, they played a dual 2-back task with feedback enabled. Their cognitive-behavioral parameters (working memory capacities, signal detection measures (hit rate, false alarm rate, sensitivity, and response bias), and reaction speed measures (response time and intrasubject response time variability)) were calculated. The effects of the sound interventions and short-term training on these working memory and attention measures were assessed statistically using mixed-model linear regressions, repeated-measures ANOVAs and ANCOVAs, Bonferroni post hoc tests, and one-sample t-tests (α = 0.05). Results The following are some major statistically significant findings (P ≤ 0.05): In the visuospatial modality, the 10 Hz BB reduced the response time and intrasubject response time variability and reduced the extent of decline over time in the case of visuospatial working memory, sensitivity, and hit rate. In the auditory-verbal modality, the 10 Hz intervention reduced the hit rate, false alarm rate, and sensitivity. The 10 Hz intervention also caused the lowest intermodality discrepancies in hit rates and false alarm rates, the highest response time discrepancies, and negative discrepancies in working memories and sensitivities (indicating the superiority of the visuospatial modality). The response biases tended to be liberal-to-neutral in the verbal modality and rather conservative in the visuospatial modality. Reactions were faster in the visuospatial modality than the auditory-verbal one, while the intrasubject variability of reaction times was smaller in the auditory-verbal modality. Short-term training can increase the hit rate, working memory, and sensitivity and can decrease the false alarm rate and response time. Aging and reduced sound intervention volume may slow down responses and increase the intrasubject variability of response time. Faster reactions might be correlated with greater hit rates, working memories, and sensitivities and also with lower false alarm rates. Conclusions The 8-minute alpha-band binaural beat entrainment may have a few, slight enhancing effects within the visuospatial modality, but not in both modalities combined. Short-term training can improve working memory and some cognitive parameters of attention. Some BB interventions can affect the intermodality discrepancies. There may be differences between the two modalities in terms of the response speeds and intrasubject response time variabilities. Aging can slow down the response, while increasing the volume of audio interventions may accelerate it.

Interpreting per capita loads of organic matter and nutrients in municipal wastewater: A study on 168 Italian agglomerations

The size of an agglomeration is expressed in population equivalent, referring to the maximum average weekly load during the year according to the European Directive 271/91. This quantity, multiplied by the daily biochemical oxygen demand (BOD) produced by one population equivalent (which is 60 g d−1 PE−1, by definition), yields the design biodegradable organic load of the wastewater treatment plant. The same agglomeration size is compared against the capacity of the wastewater treatment plant (WWTP) for plant conformity verification by the European Commission. However, field observations show remarkable fluctuations of the daily mass flows entering a WWTP, often considerably below or above the expected load calculated according to the Directive prescriptions. A wrong estimation of the real influent load adversely affects the plant design and operation, and may lead to a misleading verification of its conformity to the agglomeration. In this work, a statistical data analysis on 168 agglomerations was performed, aiming at verifying the consistency between the expected loads of BOD, chemical oxygen demand (COD), nitrogen and phosphorus and the mass flows measured at the treatment plant inlet. Only 30–40% of the total analysed cases were found having an actual load compatible with the expected one. In these cases, the average per capita daily loads of BOD, COD, nitrogen and phosphorus, calculated over 2–3 years data pools, resulted: 44.6 ± 5.9, 82.4 ± 11, 9.4 ± 1.1, and 1.08 ± 0.13 g d−1, respectively, while the daily BOD per capita production of 60 g represented a value in between the 70th and the 90th percentiles of the actual daily load distributions. For the remaining 60–70% of the total cases, variably-remarkable positive or negative discrepancies between the nominal pollutant loads generated by the agglomeration and those measured at the plant inlet could be detected and possible causes were pointed out.

The shift to pay transparency: Undermet pay standing expectations and consequences

SummaryThis research examines the shift from pay secrecy to transparency and seeks to improve the understanding of previously unrecognized negative consequences on job satisfaction. Drawing on undermet expectations research, we propose that shifting toward pay transparency decreases job satisfaction among employees who encounter negative discrepancies between expected and revealed pay standing (undermet pay standing expectations). Using data from field and experimental studies, we tested our hypotheses that episodic envy mediates the effect of undermet pay standing expectations on job satisfaction and that this indirect effect is moderated by victim sensitivity. Study 1 results suggest that undermet pay standing expectations lead to the predicted decrease in job satisfaction through episodic envy. In Study 2, we surveyed employees of a technology company before and after their shift to pay transparency and found partial support for our hypotheses, suggesting that episodic envy mediates the negative effects of undermet pay standing expectations on job satisfaction only for those low in victim sensitivity. Study 3 supported our overall model by illustrating that low victim sensitivity strengthened the negative indirect effects of undermet pay standing expectations on job satisfaction via episodic envy in an experimental study. We then discuss the implications for theory and practice.

“Worse Than What I Read?” The External Effect of Review Ratings on the Online Review Generation Process: An Empirical Analysis of Multiple Product Categories Using Amazon.com Review Data

In this paper, we study the online consumer review generation process by analyzing 37.12 million online reviews across nineteen product categories obtained from Amazon.com. This study revealed that the discrepancy between ratings by others and consumers’ post-purchasing evaluations significantly influenced both the valence and quantity of the reviews that consumers generated. Specifically, a negative discrepancy (‘worse than what I read’) significantly accelerates consumers to write negative reviews (19/19 categories supported), while a positive discrepancy (‘better than what I read’) accelerates consumers to write positive reviews (16/19 categories supported). This implies that others’ ratings play an important role in influencing the review generation process by consumers. More interestingly, we found that this discrepancy significantly influences consumers’ neutral review generation, which is known to amplify the effect of positive or negative reviews by affecting consumers’ search behavior or the credibility of the information. However, this effect is asymmetric. While negative discrepancies lead consumers to write more neutral reviews, positive discrepancies help reduce neutral review generation. Furthermore, our findings provide important implications for marketers who tend to generate fake reviews or selectively generate reviews favorable to their products to increase sales. Doing so may backfire on firms because negative discrepancies can accelerate the generation of objective or negative reviews.

A motivational framework of social comparison.

Whether people's current motivation levels increase or decline also hinge on their social environment. The current research tightly integrates motivational principles from self-regulation research with social comparison processes. In a preregistered experience sampling study including more than 5,400 social comparison situations from people's everyday life, we investigated how discrepancy assessments between the self and a comparison standard influence people's motivation and affect. Results revealed a nonlinear relationship between negative discrepancies (upward comparisons) and effort investment ("pushing"): Whereas motivational pushing increases with negative discrepancies, more extreme upward comparisons were associated with less pushing, but increased disengagement ("giving up"). The effect of negative discrepancies on pushing motivation was even more pronounced for people perceiving high control in their domain of comparison or when the domain was considered as important. Positive discrepancies (downward comparisons), on the other hand, were related to a reduction in effort ("coasting"). Similarly, emotional responses, such as an increase or decrease in self-esteem, are yet another signal for whether someone needs to invest further effort at a current time. The self-regulatory perspective on social comparison provides a novel framework uniting motivational, emotional, and cognitive processes of social comparison for a better understanding of when social comparison can benefit or hinder people's everyday goal pursuit.

When Feedback Backfires: Influences of Negative Discrepancies Between Physicians' Self and Assessors' Scores on Their Subsequent Multisource Feedback Ratings.

With multisource feedback (MSF) physicians might overrate their own performance compared with scores received from assessors. However, there is limited insight into how perceived divergent feedback affects physicians' subsequent performance scores. During 2012 to 2018, 103 physicians were evaluated twice by 684 peers, 242 residents, 999 coworkers, and themselves in three MSF performance domains. Mixed-effect models quantified associations between the outcome variable "score changes" between first and second MSF evaluations, and the explanatory variable "negative discrepancy score" (number of items that physicians rated themselves higher compared with their assessors' scores) at the first MSF evaluation. Whether associations differed across assessor groups and across a physician's years of experience as a doctor was analyzed too. Forty-nine percent of physicians improved their total MSF score at the second evaluation, as assessed by others. Number of negative discrepancies was negatively associated with score changes in domains "organization and (self)management" (b = -0.02; 95% confidence interval [CI], -0.03 to -0.02; SE = 0.004) and "patient-centeredness" (b = -0.03; 95% CI, -0.03 to -0.02; SE = 0.004). For "professional attitude," only negative associations between score changes and negative discrepancies existed for physicians with more than 6-year experience (b6-10yearsofexperience = -0.03; 95% CI, -0.05 to -0.003; SE = 0.01; b16-20yearsofexperience = -0.03; 95% CI, -0.06 to -0.004; SE = 0.01). The extent of performance improvement was less for physicians confronted with negative discrepancies. Performance scores actually declined when physicians overrated themselves on more than half of the feedback items. PA score changes of more experienced physicians confronted with negative discrepancies and were affected more adversely. These physicians might have discounted feedback due to having more confidence in own performance. Future work should investigate how MSF could improve physicians' performance taking into account physicians' confidence.

Effects of two Postprocessing Methods onto Surface Dimension of in‐Office Fabricated Stereolithographic Implant Surgical Guides

To evaluate the effects of two postprocessing methods in terms of the overall, intaglio, and cameo surface dimensions of in-office stereolithographic fabricated implant surgical guides. Twenty identical implant surgical guides were fabricated using a stereolithographic printer. Ten guides were postprocessed using an automated method. The other ten guides were postprocessed using a series of hand washing in combination with ultrasonics. Each guide was then scanned using cone-beam computed tomography to produce a set of digital imaging and communications in medicine (DICOM) files which were converted into standard tessellation language (STL) files. The STL file was then superimposed onto the original STL design file using the best fit alignment. The average positive and negative surface discrepancy differences in terms of means and variances were analyzed using t-test (α = 0.05). For the alternative group, the average positive and negative overall, intaglio, and cameo surface discrepancies were 77.38 ± 10.68 µm and -67.74 ± 6.55 µm; 78.83 ± 8.65 µm and -68.16 ± 5.26 µm; and 70.5 ± 8.48 µm -64.84 ± 5.55 µm, respectively. For the automated group, the average positive and negative overall, intaglio, and cameo surface discrepancies were 51.88 ± 4.38 µm and -170.7 ± 11.49 µm; 64.3 ± 4.44 µm and -89.45 ± 6.25 µm; and 83.59 ± 4.81 µm and -144.26 ± 13.19 µm, respectively. There was a statistical difference between the means of the two methods for the overall, intaglio, and cameo positive and negative discrepancies (p < 0.001). For a single implant tooth-supported implant guide, using hand washing with ultrasonics appeared to be consistently better than the automated method. The manual method presented with more positive discrepancies, while the automated method presented with more negative discrepancies.

Sleep Discrepancy in Patients With Comorbid Fibromyalgia and Insomnia: Demographic, Behavioral, and Clinical Correlates

Individuals with primary insomnia often have poorer self-reported sleep than objectively measured sleep, a phenomenon termed negative sleep discrepancy. Recent studies suggest that this phenomenon might differ depending on comorbidities. This study examined sleep discrepancy, its night-to-night variability, and its correlates in comorbid insomnia and fibromyalgia. Sleep diaries and actigraphy data were obtained from 223 adults with fibromyalgia and insomnia (age = 51.53 [standard deviation = 11.90] years; 93% women) for 14 days. Sleep discrepancy was calculated by subtracting diary from actigraphy estimates of sleep onset latency (SOL-D), wake after sleep onset (WASO-D), and total sleep time (TST-D) for each night. Night-to-night variability in sleep discrepancy was calculated by taking the within-individual standard deviations over 14 days. Participants completed measures of mood, pain, fatigue, sleep/pain medications, nap duration, and caffeine consumption. Average sleep discrepancies across 14 days were small for all sleep parameters (< 10 minutes). There was no consistent positive or negative discrepancy. However, sleep discrepancy for any single night was large, with average absolute discrepancies greater than 30 minutes for all sleep parameters. Greater morning pain was associated with larger previous-night WASO-D, although diary and actigraphy estimates of WASO remained fairly concordant. Taking prescribed pain medications, primarily opioids, was associated with greater night-to-night variability in WASO-D and TST-D. Unlike patients with primary insomnia, patients with comorbid fibromyalgia do not exhibit consistent negative sleep discrepancy; however, there are both substantial positive and negative discrepancies in all sleep parameters at the daily level. Future research is needed to investigate the clinical significance and implications of high night-to-night variability of sleep discrepancy, and the role of prescribed opioid medications in sleep perception.

The trade integration and Pakistan’s export performance

PurposeThe purpose of this study is to investigate the effect of trade integration on Pakistan’s export performance (value of exports, number of exporters and number of products per exporter) during 2003 to 2010.Design/methodology/approachData from the World Bank Exporters Dynamics Database are analysed using fixed effect panel data techniques.FindingsThe results suggest that trade integration with South Asian Free Trade Area (SAFTA), China and Iran play remarkable role in improving export value by 73, 29 and 55 per cent, respectively. It is found that on average more than 140 and 339 exporters increase after integration with SAFTA and China, respectively, and during the study period, 1,605 and 606 exporters entered into SAFTA and Chinese market, respectively. Moreover, 182 and 146 additional exporters entered in Malaysian and Iranian export market after integration, which is 19 and 98 per cent, respectively, of initial year’s number of exporters. In addition, Malaysia and Mauritius show positive and considerable effect on diversification of product variety.Originality/valueThis is an original empirical research. The contributions of the paper are many fold: this paper is first to analyse the effect of Pakistan’s trade integration established during 2000s decade; pioneer contribution of this study is to use the number of exporters and number of products, as well as the value of exports to measure the export performance of Pakistan; and this study uses positive and negative discrepancies in export value data, number of HS6 products exported as a proxy of product diversification, share of industrial exports in total exports and share of textile exports in industrial exports.

Asymmetric cointegration and causality between natural gas consumption and economic growth in Nigeria

This paper investigates asymmetric cointegration, asymmetric adjustment, and causality between natural gas consumption and economic growth in Nigeria using the momentum threshold autoregressive (M-TAR) model and the Granger-causality test in a momentum threshold error correction model (M-TECM). The results revealed evidence of asymmetric cointegration, asymmetric adjustment which suggests that the negative discrepancies from the equilibrium error adjust more rapidly than the positive discrepancies and that there is bidirectional causality between the two variables. The implication of the results is that a shock that decreases the impact of natural gas consumption on economic growth adjusts more rapidly than a shock that increases it and that a consistent natural gas supply increases growth and similarly a rise in growth leads to rise in natural gas consumption. Therefore, policymakers in Nigeria need to confine more attention to the shocks stemming from the decrease in natural gas consumption and the country should adopt energy exploration policies.

Subsidence transition during the post-rift stage of the Dongpu Sag, Bohai Bay Basin, NE China: A new geodynamic model

The Dongpu Sag, located in the Bohai Bay Basin, NE China, is a Cenozoic continental rift basin. The post-rift evolution of the Dongpu Sag is associated with the development of petroleum reservoirs and has implications for Neogene–Quaternary basin evolution along the eastern margin of Eurasia. To determine the nature and origin of post-rift subsidence in the Dongpu Sag, we apply backstripping, modified strain-rate inversion, and revised finite extension modelling techniques, using data from 14 real and synthetic wells that are intersected by three seismic lines. Our results reveal discrepancies by subsidence based on backstripping of well data (the observed subsidence) minus that predicted by modified strain-rate inversion and revised finite extension modelling (the predicted subsidence). During the Miocene, the observed subsidence was smaller than the predicted subsidence, leaving negative discrepancies referred to here as “insufficient subsidence” ranging from −343 to −96 m. In contrast, during the Pliocene–Quaternary the observed subsidence was greater than the predicted subsidence by +123 to +407 m, which left positive discrepancies referred to as “over-sufficient subsidence”. Therefore, we infer a transition from insufficient to over-sufficient subsidence during the post-rift stage. Normal faulting that started at ca. 5.3 Ma is estimated to have produced only ∼20% of the over-sufficient subsidence. Therefore, the remaining over-sufficient subsidence, as well as the preceding insufficient subsidence and the transition between the two, were likely controlled by lithosphere processes. We propose a new tectonic model in which variations in the conditions (e.g. rate, direction, and angle) associated with subduction of the Pacific plate resulted in a change of heat flow decreasing from a linear to a curvilinear pattern, leading to a transition from insufficient to over-sufficient subsidence.

Maternal and fetal characteristics affect discrepancies between pregnancy-dating methods: a population-based cross-sectional register study.

IntroductionGestational age is estimated by ultrasound using fetal size as a proxy for age, although variance in early growth affects reliability. The aim of this study was to identify characteristics associated with discrepancies between last menstrual period‐based (EDD‐LMP) and ultrasound‐based (EDD‐US) estimated delivery dates.Material and methodsWe identified all singleton births (n = 1 201 679) recorded in the Swedish Medical Birth Register in 1995–2010, to assess the association between maternal/fetal characteristics and large negative and large positive discrepancies (EDD‐LMP earlier than EDD‐US and 10th percentile in the discrepancy distribution vs. EDD‐LMP later than EDD‐US and 90th percentile). Analyses were adjusted for age, parity, height, body mass index, smoking, and employment status.ResultsWomen with a body mass index >40 kg/m2 had the highest odds for large negative discrepancies (−9 to −20 days) [odds ratio (OR) 2.16, 95% CI 2.01–2.33]. Other factors associated with large negative discrepancies were: diabetes, young maternal age, multiparity, body mass index between 30 and 39.9 kg/m2 or <18.5 kg/m2, a history of gestational diabetes, female fetus, shorter stature (<−1 SD), a history of preeclampsia, smoking or snuff use, and unemployment. Large positive discrepancies (+4 to +20 days) were associated with male fetus (OR 1.80, 95% CI 1.77–1.83), age ≥30 years, multiparity, not living with a partner, taller stature (>+1 SD), and unemployment.ConclusionsSeveral maternal and fetal characteristics were associated with discrepancies between dating methods. Systematic associations of discrepancies with maternal height, fetal sex, and partly obesity, may reflect an influence on the precision of the ultrasound estimate due to variance in early growth.

Caregiver perception of apathy in persons with mild cognitive impairment or Alzheimer's disease: a longitudinal study

ABSTRACTObjective: Discrepancy between self- and caregiver apathy ratings was examined longitudinally for persons with mild cognitive impairment or Alzheimer's disease. Particular focus was on the distinction between the positive and negative caregiver bias and its predictive value for a clinical diagnosis of apathy.Method: Apathy rating discrepancy was based on the apathy evaluation scale. Dyads were categorized depending on whether the caregiver reported fewer deficits (positive caregiver bias) or more deficits (negative caregiver bias) than the cognitively impaired person did.Results: Caregiver ratings and rating discrepancy showed a significant increase from baseline to follow-up. By contrast, self- and clinician ratings showed no change across the two time points. Ratings with a negative caregiver bias remained stable, while those with a positive caregiver bias showed a significant increase in the caregiver ratings but also a significant decrease in the self-ratings. A negative caregiver bias at baseline was significantly related to greater likelihood of having clinical apathy at follow-up, adjusted for an array of control variables.Conclusion: Positive and negative caregiver bias should be distinguished, as they seem to reflect distinct dyadic processes and are relevant for clinical outcome. Furthermore, negative rating discrepancies can be considered a risk factor for developing apathy.

Asymmetric Interest Rate Pass-Through to Turkish Loan Rates

This paper aims to investigate the actual nature of the interest rate pass-through to Turkish cash, automobile, housing and corporate loan rates. Focusing on the possibility of nonlinearity in the adjustment of lending rates due to financial market conditions and monetary policies, we adopt the threshold autoregressive (TAR) and momentum threshold autoregressive (MTAR) models of Enders and Siklos (2001). Empirical results suggest substantial asymmetries (nonlinearities) in all lending rates. More specifically, banks adjust their lending rates faster in response to increases in negative discrepancies from the long-run equilibrium arising from an increase in the money market rate, while they act slowly following money market rate decreases. Furthermore, the degree of reluctance of banks to follow money market rate decreases appears to vary across lending rates, suggesting the existence of sectoral heterogeneities besides asymmetries.
