Suicide rates in younger age groups in Australia, and in a number of other similar Western countries, have increased substantially since the 1960s. In Australia this rise has occurred contemporaneously with rises in youth unemployment rates, especially in males. Aggregate analyses investigating the relationship between these trends are reviewed for Australia, and compared with similar international aggregate studies of youth suicide and unemployment. Individual based studies investigating the role of unemployment in the causal pathways associated with suicide are also considered in this review. Aggregate suicide and unemployment data for males aged 20–24 years is presented to illustrate the changing relationship between unemployment and youth suicide over 1921–1998. The relationship between youth suicide rates and unemployment rates, particularly in males, is discussed in terms of the utility of using such indicators in evaluating suicide prevention initiatives. The applicability of aggregate variables in multi-dimensional explanations of suicide is also discussed.
This chapter provides a typological overview of segmental quantity in Germanic languages. It begins with an overview of basic terminology, different ways of representing quantity, and the effects of different diachronic processes (e.g., open syllable lengthening and degemination) on the occurrence of contrastive segmental quantity. After a presentation of Riad’s (1995) typology of quantity, the chapter describes North and West Germanic language varieties that preserve both vowel and consonant quantity, varieties that retain only consonant quantity and varieties that retain only vowel quantity. Also included are discussions of complementary quantity, syllable cut and evidence that some Germanic varieties no longer have contrastive segmental quantity.
The Germanic languages include some of the world’s most widely spoken and thoroughly researched languages. English has become a global language that serves as a lingua franca in many parts of the world and has an estimated 1.12 billon speakers (Simons and Fennig 2018). German, Dutch, Icelandic, Swedish, and Norwegian have also been studied and described extensively from both diachronic and synchronic perspectives. In addition to the standard varieties of these languages, there are available descriptions of many nonstandard varieties as well as of regional and minority languages, such as Frisian and Low German. There are several possibilities to consider when putting together a handbook of a language family. One would be to have a chapter devoted to each language, as in König and Auwera (1993).
The Germanic language family ranges from national languages with standardized varieties, including German, Dutch and Danish, to minority languages with relatively few speakers, such as Frisian, Yiddish and Pennsylvania German. Written by internationally renowned experts of Germanic linguistics, this Handbook provides a detailed overview and analysis of the structure of modern Germanic languages and dialects. Organized thematically, it addresses key topics in the phonology, morphology, syntax, and semantics of standard and nonstandard varieties of Germanic languages from a comparative perspective. It also includes chapters on second language acquisition, heritage and minority languages, pidgins, and urban vernaculars. The first comprehensive survey of this vast topic, the Handbook is a vital resource for students and researchers investigating the Germanic family of languages and dialects.
Biochar systems are designed to meet four related primary objectives: improve soils, manage waste, generate renewable energy, and mitigate climate change. Supply chain models provide a holistic framework for examining biochar systems with an emphasis on product life cycle and end use. Drawing on concepts in supply chain management and engineering, this chapter presents biochar as a manufactured product with a wide range of feedstocks, production technologies, and end use options. Supply chain segments are discussed in detail using diverse examples from agriculture, forestry and other sectors that cut across different scales of production and socioeconomic environments. Particular attention is focused on the environmental impacts of different production and logistics functions, and the relationship between supply chain management and life cycle assessment. The connections between biochar supply chains and those of various co-products, substitute products, and final products are examined from economic and environmental perspectives. For individuals, organizations, and broad associations connected by biochar supply and demand, achieving biochar’s potential benefits efficiently will hinge on understanding, organizing, and managing information, resources and materials across the supply chain, moving biochar from a nascent to an established industry.
All products, including bioproducts, have an impact on the environment by consuming resources and releasing emissions during their production. Biochar, a bioproduct, has received considerable attention because of its potential to sequester carbon in soil while enhancing productivity, thus aiding sustainable supply chain development. In this chapter, the environmental impacts of producing biochar using a holistic method called life-cycle assessment (LCA) or more generally life-cycle analysis are discussed. LCA is an internationally accepted method that can calculate greenhouse gas (GHG) and other emissions for part or all of a product life cycle. The present chapter will show how LCA can assess environmental impacts of the entire supply chain associated with all steps of the biochar system, from biomass harvesting through biochar production to soil amendment, with a focus on the production stage. Exploring a biochar system from a forestry LCA perspective, a new thermochemical conversion technology developed in the United States and used to process waste woody biomass, will be described. In particular, the conversion unit’s environmental performance based on the LCA research conducted so far will be described. Although this chapter will present LCA mostly from a forestry perspective, non-forestry agricultural activities will also be discussed.
