“Can We Break Through the Identity Dilemma?”: The Multiple Governance, Identities Conflict, and Self-Managements for Chinese PWUD.

Background: Exploring why the national drug policy failed is an important issue. Based on it, this study considers both the drug governance system and the voice of people who use drugs (PWUD) to analysis drug policy effects and the lives of PWUD in the Chinese context. Methods: This study takes PWUD living in urban communities as the research participants. Using qualitative research data, exploring how individual using drug experiences are identified and classified by structural forces and how individuals manage their daily life. Results: The study finds that law enforcement agencies (Narcotics Control Office (NCO), Police Station , and Community Assistance Group (CAG)) have different attitudes toward PWUD and generate different managements, forming multiple governance models, and then shaping the multiple identity dilemma. PWUD perceive the dilemma, and they adopt the strategies of spatial isolation (hidden flow), disconnection from experience (temporal isolation), and instrumental cooperation to continuously re-adjust and achieve identity recovery from the bottom-up. Conclusion/importance: Through evaluating the effectiveness of self-management strategies, this research integrates the Chinese drug rehabilitation situation, expands the specific performance of law enforcement system, and presents the limitations and positive value of self-management strategies.

The pink salmon genome: Uncovering the genomic consequences of a two-year life cycle

Pink salmon (Oncorhynchus gorbuscha) adults are the smallest of the five Pacific salmon native to the western Pacific Ocean. Pink salmon are also the most abundant of these species and account for a large proportion of the commercial value of the salmon fishery worldwide. A two-year life history of pink salmon generates temporally isolated populations that spawn either in even-years or odd-years. To uncover the influence of this genetic isolation, reference genome assemblies were generated for each year-class and whole genome re-sequencing data was collected from salmon of both year-classes. The salmon were sampled from six Canadian rivers and one Japanese river. At multiple centromeres we identified peaks of Fst between year-classes that were millions of base-pairs long. The largest Fst peak was also associated with a million base-pair chromosomal polymorphism found in the odd-year genome near a centromere. These Fst peaks may be the result of a centromere drive or a combination of reduced recombination and genetic drift, and they could influence speciation. Other regions of the genome influenced by odd-year and even-year temporal isolation and tentatively under selection were mostly associated with genes related to immune function, organ development/maintenance, and behaviour.

Imaginary Penalty and Identity Conflict: The Dilemma and Strategies of Multiple identities in Substance Abusers in Chinese Drug Policy

Background: Exploring why the national drug policy failed is an important issue. Although the theory of "Imaginary Penalty" points out the relationship between ideology and policy-making, it ignores the systemic nature of drug control and the voice of drug addicts. Methods: This study takes substance abusers who live in urban communities as the research participants. Using qualitative research data, this study explores how individual drug abuse experiences are identified and classified by structural forces and how individuals manage their daily life. Results: The study finds that law enforcement agencies (Narcotics Control Office (NCO), Police Station , and Community Assistance Group (CAG)) have different attitudes toward Substance abusers and generate different managements, forming multiple governance models, and then shaping the multiple and incomplete Substance abusers’ identity dilemma. Drug addicts perceive the dilemma, and they adopt the strategies of spatial isolation (hidden flow), disconnection from experience (temporal isolation), and instrumental cooperation to continuously re-adjust and achieve identity recovery from the bottom up with the "possible citizens" narrative logic. Conclusion/importance: Through evaluating the effectiveness of self-management strategies, this research integrates the Chinese drug rehabilitation situation, expands the specific performance of "Imaginary Penalty" in the law enforcement system, and presents the limitations and positive value of self-management strategies.

'Of Red War and Little Else': European Responses to Indigenous Violence in the Tasman World, c.1769-1850s

<p>Europeans responded to indigenous internecine violence in a variety of ways in the Tasman world from first contact to the middle of the nineteenth century. Whereas extant historiography has previously addressed European responses to Māori and Aboriginal violence in geographic and temporal isolation, a comparison spanning time and space augments knowledge of these responses. Violence was not the only aspect of indigenous societies Europeans responded to, nor was indigenous violence the only justification for colonisation. However an investigation of the ways in which Europeans represented and responded to indigenous violence enables a better understanding of the processes of the colonisation of the Tasman world. Indigenous internecine violence included cannibalism, infanticide, inter-gender violence, and inter-tribal warfare. Through a wide variety of European observations of this violence, this thesis identifies an initial conceptualisation of both New Zealand Māori and Aboriginal peoples of Australia as violent, cannibal ‘savages’. This conceptualisation was used to justify both colonisation and the related evangelical and colonial administrative attempts to suppress indigenous violence, as internecine violence was deemed ‘un-civilised’, unchristian, and unacceptable. Europeans attempted to suppress indigenous violence as it was seen both as an impediment to colonisation and, relatedly, as an inhibitor to the ‘redemption’ of indigenous peoples. While indigenous violence was seen as a barrier to colonisation, however, it was also simultaneously used to promote colonisation. Thus the attempted suppression of indigenous violence developed into the European mobilisation and utilisation of intra-Māori and intra-Aboriginal violence in the promotion of colonisation. The development of European responses to indigenous internecine violence – from conceptualisations, through attempted suppression, to utilisation – is here examined in a Tasman-world context, drawing upon the interactions between these varied responses. In tracing this development within a comparative framework, both indigenous agency and a rejection of the historiographically persistent notions of a homogenous (and harmonious) Aboriginal Australia and a homogenous Māori people during this time period are key threads.</p>

Advances in the Evolution and Ecology of 13- and 17-Year Periodical Cicadas

Apart from model organisms, 13- and 17-year periodical cicadas (Hemiptera: Cicadidae: Magicicada) are among the most studied insects in evolution and ecology. They are attractive subjects because they predictably emerge in large numbers; have a complex biogeography shaped by both spatial and temporal isolation; and include three largely sympatric, parallel species groups that are, in a sense, evolutionary replicates. Magicicada are also relatively easy to capture and manipulate, and their spectacular, synchronized mass emergences facilitate outreach and citizen science opportunities. Since the last major review, studies of Magicicada have revealed insights into reproductive character displacement and the nature of species boundaries, provided additional examples of allochronic speciation, found evidence for repeated and parallel (but noncontemporaneous) evolution of 13- and 17-year life cycles, quantified the amount and direction of gene flow through time, revealed phylogeographic patterning resulting from paleoclimate change, studied the timing of juvenile development, and created hypotheses for the evolution of life-cycle control and the future effects of climate change on Magicicada life cycles. New ecological studies have supported and questioned the role of prime numbers in Magicicada ecology and evolution, found bidirectional shifts in population size over generations, quantified the contribution of Magicicada to nutrient flow in forest ecosystems, and examined behavioral and biochemical interactions between Magicicada and their fungal parasites and bacterial endosymbionts. Expected final online publication date for the Annual Review of Entomology, Volume 67 is January 2022. Please see http://www.annualreviews.org/page/journal/pubdates for revised estimates.

The pink salmon genome: uncovering the genomic consequences of a strict two-year life-cycle

Pink salmon (Oncorhynchus gorbuscha) adults are the smallest of the five Pacific salmon native to the western Pacific Ocean. Pink salmon are also the most abundant of these species and account for a large proportion of the commercial value of the salmon fishery worldwide. A strict two-year life-history of most pink salmon generates temporally isolated populations that spawn either in even-years or odd-years.

Model-based optimization of ARINC-653 partition scheduling

The architecture of ARINC-653 partitioned scheduling has been widely applied to avionics systems owing to its robust temporal isolation among applications. However, this partitioning mechanism causes the problem of how to optimize the partition scheduling of a complex system while guaranteeing its schedulability. In this paper, a model-based optimization approach is proposed. We formulate the problem as a parameter sweep application, which searches for the optimal partition scheduling parameters with respect to minimum processor occupancy via an evolutionary algorithm. An ARINC-653 partitioned scheduling system is modeled as a set of timed automata in the model checker UPPAAL. The optimizer tentatively assigns parameter settings to the models and subsequently invokes UPPAAL to verify schedulability as well as evaluate promising solutions. The parameter space is explored with an evolutionary algorithm that combines refined genetic operators and the self-adaptation of evolution strategies. The experimental results show the applicability of our optimization method.

Effect of sowing time and density for vegetative and reproductive traits of genotypes of maize landrace in an agroecological system

ABSTRACT: Family farmers preserve the tradition of cultivating maize landrace varieties because these plants have characteristics that hybrids lack. The greatest challenge in conserving in situ on-farm genetic diversity is avoiding gene flow and genetic introgression of transgenes to landrace varieties. Thus, farmers are obliged to change sowing times to guarantee temporal isolation since most farms are small, making spatial isolation impossible. The objective of the present work was to evaluate the behavior of maize landrace varieties submitted to different sowing times and densities in an agroecological system. The test was conducted in sub-sub-divided plots, where the main plot was represented by the sowing time, the sub-plot by the genotype, and the sub-sub-plot by the density, with three replications, for two consecutive years. The results demonstrate the effect of sowing time and density on the characteristics evaluated. In western Santa Catarina, the best time to sow seeds of maize landrace varieties in an agroecological system is in September, which is when the varieties expressed the greatest potential at densities from 45,000 to 50,000 pl.ha-1 , but it will not avoid transgene contamination.
