Multidimensional Poverty: Measurement,Estimation, and Inference

Calibration in macroeconomics involves choosing fre parameters by matching certain moments of simulted models with those of data. We formally examine this method by treating the process of calibration as an econometric estimator. A numerical version of the Mehra-Prescott (1985) economy is the setting for an evaluation of calibration estimators via Monte Carlo methods. While these estimators sometimes have reasonable finite-sample properties they are not robust to mistakes in setting non-free parameters. In contrast, generalized method-of-moments (GMM) estimators have satisfactory finite-sample characteristics, quick convergence, and informational requirements less stringent than those of calibration estimators. In dynamic equilibrium models in which GMM is infeasible we offer some suggestions for improving estimates based on calibration methodology.

Derrick Bell,CRT, and educational leadership 1995–present

Critical Race Theory (CRT) has become a centered conceptual framework to understand American education and reform (Ladson-Billings and Tate 1995; Solorzano and Yosso; 2001; Decuir and Dixon 2004). Indeed, educational leadership scholars have not been far behind in recognizing the explicative and powerful role of CRT studies in their work (Lopez 2003; Parker and Villalpando 2007). As we acknowledge the role of CRT, we cannot do so without reflecting on the life and works of the quintessential Critical Legal Studies (CLS) scholar Derrick Bell (1930–2011). In this article, we use Bell’s collective works to analyze current trends and research in educational leadership. We bring his works into conversation not only with conceptions of instructional and distributed leadership, but with the palpability that CRT has on the current state of educational reform. More specifically, we use Bell’s theories of interest convergence and conversations around ‘racial remedies’ to understand two recent trends in educational leadership: discourses of social justice leadership and the move toward data-driven leadership behaviors. We ask questions like: what has been the impact of research discourses social justice on the education of African American and Latino urban youth? And, how has the current social structures benefited from such discourses? We conclude with recommendations for educational leadership researchers and professors, and encourage them to consider race as an integral part of their works.     

Supply Chain Knowledge and Performance: A Meta‐Analysis

Many firms make significant investments into developing and managing knowledge within their supply chains. Such investments are often prudent because studies indicate that supply chain knowledge (SCK) has a positive influence on performance. Key questions still surround the SCK–performance relationship, however. First, what is the overall relationship between SCK and performance? Second, under what conditions is the relationship stronger or weaker? To address these questions, we applied meta‐analysis to 35 studies of the SCK–performance relationship that collectively include more than 8,400 firms. Our conservative estimate is that the effect size of the overall relationship is  = .39. We also find that the SCK–performance relationship is stronger when (i) examining operational performance, (ii) gathering data from more than one supply chain node, (iii) gathering data from multiple countries, (iv) examining service industries, and (v) among more recently published studies. We also found that studies that embraced a single theory base (as opposed to using multiple ones) had a stronger SCK–performance relationship. Looking to the future, our meta‐analysis highlights the need for studies to (i) include lags between the measurement of SCK and performance, (ii) gather upstream data when examining innovation, (iii) examine SCK within emerging countries, and (iv) provide much more information relative to the nuances of the SCK examined.

What do urban college students really think about health insurance? A qualitative study

Abstract

Objective: To determine barriers and opportunities to health insurance enrollment among an undergraduate students at a large urban university. Participants: Participants were 31 college students enrolled in 4-year and community colleges in the City University of New York (CUNY), and six health services and insurance enrollment specialists who facilitate and assist in the health insurance enrollment process for CUNY students. Methods: Focus groups were conducted with students and in-depth interviews with key informants in May 2017. Results: The research revealed important insights into how students perceive and value insurance and yielded recommendations for the university to improve enrollment of its students. Conclusions: Many colleges can increase student enrollment in health insurance by informing and educating students about the process. Improving enrollment processes can increase insurance rates and improve student population health.

Attachment Style,Vagal Tone,and Empathy During Mother–Adolescent Interactions

We tested associations among empathic responsiveness, attachment style, and vagal tone (a physiologic index of emotion regulation) in 103 mother–adolescent dyads. Dyads discussed positive and negative topics and then separately reviewed a videotape of the interaction and rated their own and the other person's affect at one‐minute intervals. We used multilevel modeling to analyze the association between one's rating of the other person's affect and the other person's affect (empathic sensitivity), and the association between one's rating of the other person's affect and one's own affect (perceived concordance). Adolescents’ empathic responsiveness was predicted by attachment style, vagal tone, and interactions between them. Adolescents with the greatest empathic responsiveness had low levels of attachment insecurity and high levels of vagal tone.     

Discrete random vectors generated by Taylor expansions

We demonstrate how univariate discrete and multivariate discrete distributions can be generated using Taylor expansions. Some of the results involve use of Bell polynomials.
