Summary: In this paper, a piecewise linear trend model is used to model the trajectory of COVID-19 cumulative confirmed cases and deaths. The model captures the phase transitions of the epidemic growth rate and provides interpretability due to its semiparametric nature. The self-normalization technique is advanced for testing and estimation of change-points in the linear trend of a nonstationary time series. Multiple change-point estimation is achieved through the combination of SN-based change-point test and the NOT algorithm. The proposed method is applied to analyze the trajectory of COVID-19 cases and deaths for 30 major countries, revealing interesting patterns and potential implications for pandemic responses.

Summary: Psychology research often involves studying probabilities and counts using generalized linear models (GLMs). Interactions in GLMs describing probabilities and counts are not equal to product terms between predictor variables, requiring nontraditional approaches to accurately interpret these effects. This paper introduces the use of partial derivatives and discrete differences to quantify and interpret interaction effects in GLMs, and provides guidelines and simulated examples for estimating and interpreting these effects on probability and count scales.

Summary: This article examines the challenges in interview research of assessing whether what people say motivated their actions actually did so. It identifies at least five challenges and more than a dozen strategies that have been deployed to address them. The article argues that researchers need to consider each challenge, use appropriate strategies, and evaluate their effectiveness to uncover motivation. This work helps strengthen the scientific foundations of in-depth interview research.

Summary: This study summarizes the commonly used spatial regression models, comparing their performance through Monte Carlo experiments. It finds that spatial Durbin specifications (SDM and SDEM) and simple spatial lag of X (SLX) provide more accurate estimates of direct impacts compared to spatial autoregressive and spatial error specifications, even in cases of misspecification. Additionally, the study reveals that in certain realistic scenarios, SLX outperforms the more complex SDM and SDEM specifications for indirect spillover effects.

Summary: Recent debates on qualitative methods have examined the limitations and contributions of interviews compared to surveys and participant observation. However, little consideration has been given to how ethnographers themselves use interviews in their work. This article argues that Lizardo's discussion of the three modes of culture can help us better understand the distinct contributions of observation and interviews, with ethnographic interviews being particularly valuable for accessing different cultural modes. The authors also propose dividing Lizardo's conception of public culture into meso- and macrolevels, which helps highlight the varying contributions of interviews within and outside an ethnographic context. Drawing on ethnographic research and analysis, the article demonstrates how using ethnographic interviews can enhance sociologists' understanding of the interaction between these four cultural modes.

Summary: Medical errors pose high risks to patients. Limited research is available regarding the probabilistic interdependencies between organizational factors and patient safety errors. This study uses a data-driven Bayesian Belief Network (BBN) model to explore the relationships between organizational factors and patient safety errors, and identifies health and well-being and bullying and harassment in the work environment as the two leading factors influencing patient safety.

Summary: Idiographic modeling is gaining popularity for accessing within-person dynamics in psychological phenomena, but making inferences to underlying systems from time series models is challenging, and insufficient sampling frequency can impact recovery of dynamics of interest. However, global characteristics of the system can still be reliably recovered.

Summary: This study elicits subjective probability distributions from business executives about their own-firm outcomes in the future. The results show that firm-level growth expectations are highly predictive of realized growth rates. Furthermore, firm-level subjective uncertainty predicts the magnitudes of future forecast errors and revisions. The study also finds that subjective uncertainty increases with the firm's absolute growth rate in the previous year and recent revisions to its expected growth rate. The researchers construct monthly indices of business expectations and uncertainty for the U.S. private sector.

Summary: This paper evaluates the economic consequences of the 76-day lockdown policy in Hubei Province during the COVID-19 pandemic. The strict lockdown had a significant negative impact on the economy, but it also effectively controlled the spread of the virus. After the lockdown was lifted, the economy in Hubei quickly recovered, with the exception of the passenger transportation sector.

Summary: Fixed effects (FE) panel models have been widely used in research to control for stable heterogeneity between units. However, conventional FE models may produce biased results when there are heterogeneous slopes or growth curves related to the parameter of interest. This study introduces fixed effects individual slope (FEIS) models to overcome this issue and proposes two versions of the Hausman test to detect misspecification in FE models.

Summary: The objective of qualitative comparative analysis is to find solutions that meet the conditions for a desired outcome, while being as simple as possible. Different search strategies lead to different types of solutions, and there is an ongoing debate on which type is closest to the true causal structure. This article introduces the logics behind each simplification system, explores the concept of robust sufficiency, and provides improved procedures to measure correctness.

Summary: This study reveals the risk-transmitting pathways within different economic sectors in China, identifying sectors that act as risk transmitters and risk takers. It also shows that during extreme risk events, such as the global financial crisis and the China-US trade war, the financial sectors play a crucial role in stabilizing the economic system.

Summary: The behavior of fit indices in CFA models depends on factors such as model size, sample size, and measurement quality. Biased estimators of fit indices result in unstable behavior with changing sample size, making it difficult to establish cutoff values. Unbiased estimators, on the other hand, match the behavior of population parameters and depend on the average R-2 of observed variables and model size.
