Children’s Health in a Legal Framework

The interdisciplinary periodical Future of Children has dedicated an issue to children’s health policy. This contribution to the issue maps the legal landscape influencing policy choices. The authors demonstrate that in the U.S. legal system, parents have robust rights, grounded in the Constitution, to make decisions concerning their children’s health and medical treatment. Following from its commitment to parental rights, the system typically assumes the interests of parents and children are aligned, even when that assumption seems questionable. Thus, for example, parents who would limit their children’s access to health care on the basis of the parents’ religious belief have considerable latitude to do so, unless the child’s life is imminently threatened. There are some exceptions to this legal regime. Adolescents have the right to obtain some health services independently; in these contexts, social welfare needs such as pregnancy prevention trump parental rights. Minors also have access to abortion (although this right is more restricted than for adults). Moreover, the state has the power to intervene when parents place their children’s health at risk through abuse or neglect. A hallmark feature of the legal regime based on parental rights is that the state has no affirmative obligation to help parents care for their children’s health needs. This libertarian framing of the family-state relationship has profound implications for the development of public policy. To the extent the state provides support for families and children, it is doing so as a matter of policy choice (as with Medicaid and the Children’s Health Insurance Program) and not enforceable legal obligation. The importance of family autonomy thus results in a weak conception of shared responsibility for children. The framework also means that the state often takes a reactive approach to child wellbeing, intervening primarily when families have broken down or parents have seriously defaulted on their duties. Appreciation of the legal framework underscores the need to develop political support for any initiative to improve health services for children. Often, as this article shows, the state intervenes to promote children’s health only in response to compelling social welfare needs such as crime or disease prevention, or to crises in which parents abuse their children or fail to provide adequate care

Diamond chemical vapor deposition on optical fibers for fluorescence waveguiding

A technique has been developed for depositing diamond crystals on the endfaces of optical fibers and capturing the fluorescence generated by optically active defects in the diamond into the fiber. This letter details the diamond growth on optical fibers and transmission of fluorescence through the fiber from the nitrogen-vacancy (N-V) color center in diamond. Control of the concentration of defects incorporated during the chemical vapor deposition (CVD) growth process is also demonstrated. These are the first critical steps in developing a fiber coupled single photon source based on optically active defect centers in diamond.Comment: 10 pages, 3 figure

Multi-Gain-Stage InGaAs Avalanche Photodiode with Enhanced Gain and Reduced Excess Noise

We report the design, fabrication, and test of an InGaAs avalanche photodiode (APD) for 950-1650 nm wavelength sensing applications. The APD is grown by molecular beam epitaxy on InP substrates from lattice-matched InGaAs and InAlAs alloys. Avalanche multiplication inside the APD occurs in a series of asymmetric gain stages whose layer ordering acts to enhance the rate of electron-initiated impact ionization and to suppress the rate of hole-initiated ionization when operated at low gain. The multiplication stages are cascaded in series, interposed with carrier relaxation layers in which the electric field is low, preventing avalanche feedback between stages. These measures result in much lower excess multiplication noise and stable linear-mode operation at much higher avalanche gain than is characteristic of APDs fabricated from the same semiconductor alloys in bulk. The noise suppression mechanism is analyzed by simulations of impact ionization spatial distribution and gain statistics, and measurements on APDs implementing the design are presented. The devices employing this design are demonstrated to operate at linear-mode gain in excess of 6000 without avalanche breakdown. Excess noise characterized by an effective impact ionization rate ratio below 0.04 were measured at gains over 1000

Conceptualizing Legal Childhood in the Twenty-First Century

The law governing children is complex, sometimes appearing almost incoherent. The relatively simple framework established in the Progressive Era, in which parents had primary authority over children, subject to limited state oversight, has broken down over the past few decades. Lawmakers started granting children some adult rights and privileges, raising questions about their traditional status as vulnerable, dependent, and legally incompetent beings. As children emerged as legal persons, children’s rights advocates challenged the rationale for parental authority, contending that robust parental rights often harm children. And a wave of punitive reforms in response to juvenile crime in the 1990s undermined the state’s long-standing role as the protector of children. We address this seeming incoherence by identifying a deep structure and logic in the regulation of children that is becoming clear in the twenty-first century. In our conceptual framework, the law’s central goal, across multiple legal domains, is to promote child wellbeing. This unifying purpose has roots in the Progressive Era, but three distinct characteristics distinguish the modern approach. Today, lawmakers advance child wellbeing with greater confidence and success by drawing on a wide body of research on child and adolescent development and the efficacy of related policies. This is bolstered by the clear understanding that promoting child wellbeing generally furthers social welfare, leading to a broader base of support for state policies and legal doctrines. Finally, there is a growing recognition that the regulation of children and families has long been tainted by racial and class bias and that a new commitment to minimizing these pernicious influences is essential to both the legitimacy and fairness of the regime. In combination, these features make the contemporary regulatory framework superior to earlier approaches. Rather than pitting the state, parents, and child in competition for control over children’s lives—the conception of family regulation since the 1960s—our Child Wellbeing framework offers a surprisingly integrated regulatory approach. Properly understood, parental rights and children’s rights, as well as the direct role of the state in children’s lives, are increasingly defined and unified by a research-driven, social-welfare-regarding effort to promote child wellbeing. This normatively attractive conceptualization of legal childhood does not define every area of legal regulation, but it is a strong through-line and should be elevated and embraced more broadly. In short, our framework brings coherence to the complex legal developments of the past half-century and provides guidance moving forward for this critical area of the law
