This paper provides a selective survey of the panel macroeconometric techniques that focus on controlling the impact of “unobserved heterogeneity” across individuals and over time to obtain valid inference for “structures” that are common across individuals and over time. We consider issues of (i) estimating vector autoregressive models; (ii) testing of unit root or cointegration; (iii) statistical inference for dynamic simultaneous equations models; (iv) policy evaluation; and (v) aggregation and prediction.

This paper considers stationary regression models with near-collinear regressors. Limit theory is developed for regression estimates and test statistics in cases where the signal matrix is nearly singular in finite samples and is asymptotically degenerate. Examples include models that involve evaporating trends in the regressors that arise in conditions such as growth convergence. Structural equation models are also considered and limit theory is derived for the corresponding instrumental variable (IV) estimator, Wald test statistic, and overidentification test when the regressors are endogenous. It is shown that near-singular designs of the type considered here are not completely fatal to least squares inference, but do inevitably involve size distortion except in special Gaussian cases. In the endogenous case, IV estimation is inconsistent and both the block Wald test and Sargan overidentification test are conservative, biasing these tests in favor of the null.

Much of the discussion surrounding the antivaccine movement focuses on the decision of parents to not vaccinate their children and the resulting danger posed to others. However, the primary risk is borne by the child left unvaccinated. Although living in a developed country with high vaccination rates provides a certain amount of protection through population immunity, the unvaccinated child is still exposed to a considerably greater risk of preventable diseases than one who is vaccinated. I explore the tension between parental choice and the child’s right to be free of preventable diseases. The chapter’s goal is twofold: to advocate for moving from a dyadic framework – considering the interests of the parents against those of the state – to a triadic one, in which the interests of the child are given as much weight as those of the parent and the state; and to discuss which protections are available, and how they can be improved. Specific legal tools available to protect that child are examined, including tort liability of the parents to the child, whether and to what degree criminal law has a role, under what circumstances parental choice should be overridden, and the role of school immunization requirements in protecting the individual child.

It has become increasingly apparent that one's perception of issues depends largely on his or her personal history. Human beings, professionals, and stakeholders vary in their perspectives, strategies, and solutions. Rather than arbitrarily selecting issues or seeking consensus among interdisciplinary but disparate groups, it is critical to examine the broader array of values and issues that impact learners with exceptionalities and the future of special education. In addition, it is important to conceptualize effective techniques to reverse traditional problems or difficulties while considering the “cycles” of change in general and special education. These cycles are based on the view that educational perspectives have their time since they come and go. When they are innovative, they become the status quo and become finally obsolete as the next group of methods, beliefs, and educational initiatives takes hold. In special education, we have fundamental values that must be respected and followed to deliver services to learners with exceptionalities. These values are sometimes not valued by ill prepared and unprepared professionals, especially since good professionals believe in change. This chapter focuses on how these values can be respected to protect and advance special education and education as a whole.

In this chapter, we explore the lived experiences of transgender and gender non-conforming (TGNC) prisoners, arguably the most vulnerable minority in the prison estate, using the data from our correspondence study with transgender women and non-binary individuals incarcerated in male establishments in England and Wales. We provide a brief review of the extant literature, describe the English prison system and the regulations concerning transgender prisoners, and analyze two axes of vulnerability of TGNC prisoners: social (stemming from relationships between prisoners) and institutional (resulting from the prison regime). Along the social axes, we find, in contrast with prior research, that our respondents defied the stereotypes of trans prisoners as submissive to males in a hypermasculine prison society and as involved primarily in abusive relationships. Along the institutional axes, we find that, despite the progressive by international standards transgender prison regulations, prisoners were subject to vicissitudes in treatment that negatively affected their ability to express their gender and their health. Focusing on access to gender-affirming items (clothing, prosthetics, make-up) and gender-affirming medical treatment, we develop recommendations for the prison service that could improve the conditions of confinement for TGNC prisoners.
