Age Determinations

The importance of chronometric dating in archaeology cannot be overemphasized. Indeed, most chronologies developed throughout the world during the past three decades have depended on radiocarbon age determinations to provide a temporal framework for examining change over time in cultural sequences during the late Pleistocene and Holocene. With the advent of legislation in the mid-1960s designed to protect archaeological sites in the United States threatened by increased urban development or government sponsored projects, archaeological surveys and excavations were mandated as a means for preserving information otherwise destroyed. As a result, thousands of projects have contributed to a growing body of “gray literature,” ie, unpublished proprietary or manuscript reports with very limited circulation. Within these reports are hundreds, if not thousands, of 14C age determinations, most of which are not accessible in published form. One objective of this paper is to present all the 14C age determinations for the island of Moloka'i, Hawai'i as of December 1988, including 41 dates never before published with stratigraphic details.

Over Time

In the past, physical barriers such as geography and distance limited global communication. In this paper, we explore how young children in immigrant families engage in transnational literacy practices. Specifically, we explore the transnational funds of knowledge that result from those experiences. This three-year longitudinal collective case study involves ten children from immigrant families who have come to the United States from around the world. The students entered the study in four-year-old kindergarten, grade 1 or grade 2. Each year, we collected observations, spoken data and student-created artefacts (e.g. writing samples, maps, photographs). Data sources were designed to highlight the various spaces that the immigrant families occupy or have occupied over time (i.e. home/neighbourhood/ school; native country/country of residence). Our reading and rereading of coded data across the sample led us to focus on families’ digital transnational practices and children’s transnational awareness. We argue that these funds of knowledge should be recognized in classrooms and schools and that they have the potential to contribute to the nurturing of cosmopolitan perspectives for all children.

Key Aspects

Around the world, people nearing and entering retirement are holding ever-greater levels of debt than in the past. This is not a benign situation, as many pre-retirees and retirees are stressed about their indebtedness. Moreover, this growth in debt among the older population may render retirees vulnerable to financial shocks, medical care bills, and changes in interest rates. Contributors to this volume explore key aspects of the rise in debt across older cohorts, drill down into the types of debt and reasons for debt incurred by the older population, and review policies to remedy some of the financial problems facing older persons, in the United States and elsewhere. The authors explore which groups are most affected by debt, and they also identify the factors causing this important increase in leverage at older ages. It is clear that the economic and market environments are influential when it comes to saving and debt. Access to easy borrowing, low interest rates, and the rising cost of education have had important impacts on how much people borrow, and how much debt they carry at older ages. In this environment, the capacity to manage debt is ever more important as older workers lack the opportunity to recover for mistakes.

Antlion Larvae

AbstractNymphidae, the group of split-footed lacewings, is a rather species-poor group. Split-footed lacewings nowadays are restricted to Australasia, while fossil forms are also known from other areas of the world, indicating that the group was more species-rich and therefore likely diverse in the past. Split-footed lacewings have rather distinct larvae, roughly resembling antlion larvae, but differing from the latter especially with regard to the mandibles. Antlion larvae usually have three prominent teeth on each mandible, while at least extant larvae of split-footed lacewings only have a single prominent tooth per mandible. Fossils interpreted as larvae of split-footed lacewings are well known from amber from Myanmar (ca. 100 myr; Burmese amber) and by a single specimen from Baltic amber (about 40 myr). We here report additional fossil specimens from Myanmar amber, expanding the known record of fossil forms from six depicted specimens to 15. For the extant fauna, we could compile 25 larvae. We compare the diversity of shape of extant and fossil larvae through time using an outline analysis (based on elliptic Fourier transformation) of the head. The results of this analysis indicate that the morphological diversity, or disparity, of split-footed lacewing larvae was higher in the past than it is today. With this type of analysis, we can show a loss of diversity over time, without the necessity to identify the fossil larvae down to a narrow taxonomical range. A similar pattern has already been recognised in silky lacewings, Psychopsidae. This might indicate a general loss of diversity of lacewing larvae.

Over Time

Nuclear weapon free zones (NWFZs) were an important development in the history of nuclear nonproliferation efforts. From 1957 through 1968, when the Treaty of Tlatelolco was signed, the United States struggled to develop a policy toward NWFZs in response to efforts around the world to create these zones, including in Europe, Africa, Latin America, and the Middle East. Many within the U.S. government initially rejected the idea of NWFZs, viewing them as a threat to U.S. nuclear strategy. However, over time, a preponderance of officials came to see the zones as advantageous, at least in certain areas of the world, particularly Latin America. Still, U.S. policy pertaining to this issue remained conservative and reactive, reflecting the generally higher priority given to security policy than to nuclear nonproliferation.

AbstractMussel shells from central California coastal archaeological sites record changes in sea surface temperatures in the past 2000 years. Water temperatures, inferred from oxygen isotopes in the shells, were about 1°C cooler than present and stable between 2000 and 700 yr ago. Between about 700 and 500 yr ago, seasonal variation was greater than present, with extremes above and below historic levels. Water temperatures were 2–3°C cooler than today 500–300 yr ago. The interval of variable sea temperatures 700–500 yr ago partially coincided with an interval of drought throughout central California. A coincident disruption in human settlement along the coast suggests movements of people related to declining water sources. Quantities of fish bone in central coast middens dating to this same period are high relative to other periods, and the remains of northern anchovies, a species sensitive to changing oceanographic conditions, are also abundant. The continued use of local fisheries suggests that changes in settlement and diet were influenced more by drought than by a decrease in marine productivity, as fish provided a staple during an interval of low terrestrial productivity.

Historic monuments are the most public and recognized forms of commemoration. In Canada, as around the world, many monuments have come under fire recently for celebrating a vision of the past that is no longer palatable to large segments of the population. The heroes and events they enshrine have been denounced by many as tributes to racism, yet they are valued by others as aspects of our collective history and a celebration of our national heritage. Both these positions gloss over the complexity of the historical act of raising monuments and interpreting their historical meanings. Monuments in Canada, like all forms of commemoration, are reflections of the historiographical and methodological trends contemporary to the discipline of history at the time of their creation. Changes in methods and interpretations have thus also affected their meaning over time. Thus, monuments are not straightforward representations of history but, instead, layered expressions of historiography in physical form. Ascribing to them singular meanings obscures the complexity of the societies that constructed them and simplifies their connections to public life.

India has emerged as a leading voice in global affairs in the past two decades. Its fast-growing domestic market largely explains the ardour with which Delhi is courted by powers great and small. India is also becoming increasingly important to global geostrategic calculations, being the only Asian country with the heft to counterbalance China over time. Nevertheless, India’s foreign policy has been relatively neglected in the existing literature. ThisHandbook, edited by three widely recognized students of the topic, provides an extensive survey of India’s external relations. The authors include leading Indian scholars and commentators of the field and several outstanding foreign scholars and practitioners. They address factors in Indian foreign policy flowing from both history and geography and also discuss key relationships, issues, and multilateral forums through which the country’s international relations are refracted.

Socialist Market

In the past seventy–five years, developing Asia has transformed more rapidly than any other region. What is behind this success? Will Asia go on to lead the world, or will its rise encounter obstacles? Asia is politically diverse, with democracies, hybrid governments and numerous authoritarian regimes. Several are unstable. Paths to prosperity have varied, including the East Asian model, China’s “socialist market economy”, Indian self–reliance, and economic transition in Central Asia. Regional cooperation is chronically weak, due to the youthfulness, dispersion and diversity of Asia’s sovereign states. China’s rise threatens to fracture the region further. As the region emerges from the Covid–19 crisis, East Asia is well positioned to lead an economic recovery. However, many challenges remain. Political and governance systems are weak. Territorial disputes could escalate into open conflict, including Taiwan. Human capital is poorly developed, and populations are aging. Finally, the region could be polarized between the United States and China.

In the past 16 years, research on mitophagy has increasingly expanded to a wider range of subjects. Therefore, comprehensively analyzing the relevant progress and development trends on mitophagy research requires specific methods. To assess the hotspots, directions, and quality of results in this field worldwide, we used multiple tools to examine research progress and growing trends in research on the matter during the last 16 years (from 2005 to 2020). We also compared the quantity and quality of the literature records on mitophagy published by research institutions in China and other developed countries, reviewed China’s contribution, and examined the gap between China and these developed countries. According to the results of our bibliometric analysis, the United States and its research institutes published the most papers. We identified cell biology as the most commonly researched subject on mitophagy and AUTOPHAGY as the most popular journal for research on mitophagy. We also listed the most cited documents from around the world and China. With gradually increased funding, China is progressively becoming prominent in the field of mitophagy; nevertheless, the gap between her and major countries in the world must be closed.
