Always in control? Sovereign states in cyberspace
Authors: Mainwaring Sarah 
Published: May 2020

AbstractFor well over twenty years, we have witnessed an intriguing debate about the nature of cyberspace. Used for everything from communication to commerce, it has transformed the way individuals and societies live. But how has it impacted the sovereignty of states? An initial wave of scholars argued that it had dramatically diminished centralised control by states, helped by a tidal wave of globalisation and freedom. These libertarian claims were considerable. More recently, a new wave of writing has argued that states have begun to recover control in cyberspace, focusing on either the police work of authoritarian regimes or the revelations of Edward Snowden. Both claims were wide of the mark. By contrast, this article argues that we have often misunderstood the materiality of cyberspace and its consequences for control. It not only challenges the libertarian narrative of freedom, it suggests that the anarchic imaginary of the Internet as a ‘Wild West’ was deliberately promoted by states in order to distract from the reality. The Internet, like previous forms of electronic connectivity, consists mostly of a physical infrastructure located in specific geographies and jurisdictions. Rather than circumscribing sovereignty, it has offered centralised authority new ways of conducting statecraft. Indeed, the Internet, high-speed computing, and voice recognition were all the result of security research by a single information hegemon and therefore it has always been in control.
Are Epistemic Norms Fundamentally Social Norms?
Authors: Henderson David 
Published: May 2020

AbstractPeople develop and deploy epistemic norms – normative sensibilities in light of which they regulate both their individual and community epistemic practice. There is a similarity to folk's epistemic normative sensibilities – and it is by virtue of this that folk commonly can rely on each other, and even work jointly to produce systems of true beliefs – a kind of epistemic common good. Agents not only regulate their belief forming practices in light of these sensitivities, but they make clear to others that they approve or disapprove of practices as these accord with their sensibilities – they thus regulate the belief forming practices of others in an interdependent pursuit of a good – something on the order of a community stock of true beliefs. Such general observations suggest ways in which common epistemic norms function as social norms, as these are characterized by Cristina Bicchieri's (2006) discussion of various kinds of norms. I draw on this framework – together with an important elaboration in Bicchieri (2017) – as it affords an analysis of the various related ways in which normative sensibilities function in communities of interdependent agents. The framework allows one to probe how these normative sensibilities function in the various associated choice situations. I argue that epistemic norms are fundamentally social norms, and, at the same time, they also are widely shared sensibilities about state-of-the-art ways of pursuing projects of individual veritistic value. The two foundations suggest the analogy of an arch.
Framing the concept of invasive species “impact” within a management context
Authors: Barney Jacob N. , Tekiela Daniel R. 
Published: May 2020

AbstractGovernments and conservation organizations worldwide are motivated to manage invasive species due to quantified and perceived negative ecological and economic impacts invasive species impose. Thus, determining which species cause significant negative impacts, as well as clear articulation of those impacts, is critical to meet conservation priorities. This process of determining which species warrant management can be straightforward when there are clear negative impacts, such as dramatic reductions in native diversity. However, the majority of changes to ecosystem pools and fluxes cannot be readily categorized as ecologically negative or positive (e.g., lower soil pH). Additionally, diverse stakeholders may not all agree on impacts as negative. This complexity challenges our ability to simply and uniformly determine which species cause negative impact, and thus which species merit management, especially as we expand invader impacts to encompass a more holistic ecosystem perspective beyond biodiversity and consider stakeholder perspectives and priorities. Thus, we suggest impact be evaluated in a context that is dictated by governing policies or conservation/land management missions with the support of scientists. In other words, within each jurisdiction, populations are identified as causing negative impact based on the hierarchical governing policies and mission of that parcel. Framing negative impact in a management context has the advantages of (1) easily scaling from individual landscapes to geopolitical states; (2) better representing how managers practice, (3) reflecting invasive species as spatially contextual, not universal, and (4) allowing for flexibility with dynamic ecosystems undergoing global change. We hope that framing negative impact in an applied context aids management prioritization and achieving conservation goals.
The Effect of Rotation on Propagation of Rayleigh Wave in an Incompressible Monoclinic Elastic Solid
Authors: Kaur Baljinder , Singh Baljeet 
Published: May 2020

ABSTRACTIn this paper, the Rayleigh wave propagation is investigated in rotating half-space of incompressible monoclinic elastic materials which are subjected to the impedance boundary conditions. In particular, the explicit secular equation of the Rayleigh wave is obtained. The main objective of this paper is to illustrate the dependence of dimensionless speed of Rayleigh wave on rotation, anisotropy and impedance parameters. An algorithm in MATLAB software is developed to solve the secular equation of Rayleigh wave. The speed of Rayleigh wave is plotted against rotation, anisotropy and impedance parameters.
Strong convergence of multivariate maxima
Authors: Falk Michael , Padoan Simone A. , Rizzelli Stefano 
Published: May 2020

AbstractIt is well known and readily seen that the maximum of n independent and uniformly on [0, 1] distributed random variables, suitably standardised, converges in total variation distance, as n increases, to the standard negative exponential distribution. We extend this result to higher dimensions by considering copulas. We show that the strong convergence result holds for copulas that are in a differential neighbourhood of a multivariate generalised Pareto copula. Sklar’s theorem then implies convergence in variational distance of the maximum of n independent and identically distributed random vectors with arbitrary common distribution function and (under conditions on the marginals) of its appropriately normalised version. We illustrate how these convergence results can be exploited to establish the almost-sure consistency of some estimation procedures for max-stable models, using sample maxima.
Branching processes in a random environment with immigration stopped at zero
Authors: Dyakonova Elena , Li Doudou , Vatutin Vladimir , Zhang Mei 
Published: May 2020

AbstractA critical branching process with immigration which evolves in a random environment is considered. Assuming that immigration is not allowed when there are no individuals in the population, we investigate the tail distribution of the so-called life period of the process, i.e. the length of the time interval between the moment when the process is initiated by a positive number of particles and the moment when there are no individuals in the population for the first time.
A functional limit theorem for general shot noise processes
Authors: Iksanov Alexander , Rashytov Bohdan 
Published: May 2020

AbstractBy a general shot noise process we mean a shot noise process in which the counting process of shots is arbitrary locally finite. Assuming that the counting process of shots satisfies a functional limit theorem in the Skorokhod space with a locally Hölder continuous Gaussian limit process, and that the response function is regularly varying at infinity, we prove that the corresponding general shot noise process satisfies a similar functional limit theorem with a different limit process and different normalization and centering functions. For instance, if the limit process for the counting process of shots is a Brownian motion, then the limit process for the general shot noise process is a Riemann–Liouville process. We specialize our result for five particular counting processes. Also, we investigate Hölder continuity of the limit processes for general shot noise processes.
Great expectations: millennial lawyers and the structures of contemporary legal practice
Authors: Bleasdale Lydia , Francis Andrew 
Published: May 2020

AbstractThis paper presents the findings of the first empirical study of the experiences of young lawyers who have entered an increasingly uncertain profession following a highly competitive education and recruitment process. These ‘millennial lawyers’ are framed by a narrative of ‘difference’. This ‘difference’ is commonly articulated negatively and as a challenge to organisational and professional norms. However, our findings suggest a more complex reality. In its synthesis of work on structure and agency, with the temporal focus required by generational sociology, this paper advances an original approach to the analysis of organisational and professional change within contemporary legal practice. Drawing on new empirical research, it demonstrates that although our sample shares many field-level expectations, there is also considerable stress, unhappiness and discomfort. This is generated by a complex interaction between the lawyers’ expectations of practice, and the structuring properties of the field. Thus, the capacity for organisational and professional change is more comprehensively understood within a temporal frame. This paper challenges academic and professional paradigms of generational change within the legal field. It concludes with recommendations for legal educators and the profession which foreground the complexity of millennial lawyers’ expectations of practice.
A simple and efficient transfection protocol for Cryptosporidium parvum using Polyethylenimine (PEI) and Octaarginine

Published: May 2020

AbstractThe transfection of Cryptosporidium represents a major challenge, and current protocols are based on electroporation of freshly excysted sporozoites using a rather large amount of plasmid DNA which typically has a very poor yield. In this study, we report a fast and simple protocol for transfection of Cryptosporidium parvum that takes advantage of the DNA condensing power of the poly cationic polymer polyethylenimine (PEI) and the gene delivery property of the short cell-penetrating peptide octaarginine. Our novel protocol requires a very low amount of plasmid DNA and does not necessitate special laboratory equipment to be performed. Transfection appears to be more efficient in oocysts just triggered for excystation than the excysted sporozoites. Altogether, the application of octaarginine with PEI allows efficient transfection. To the best of our knowledge, this is the first report on an electroporation-free protocol for transfection of sporozoites of a Cryptosporidium species.

AbstractGastrointestinal helminth infection likely affects the gut microbiome, in turn affecting host health. To investigate the effect of intestinal parasite status on the gut microbiome, parasitic infection surveys were conducted in communities in Nan Province, Thailand. In total, 1047 participants submitted stool samples for intestinal parasite examination, and 391 parasite-positive cases were identified, equating to an infection prevalence of 37.3%. Intestinal protozoan species were less prevalent (4.6%) than helminth species. The most prevalent parasite was the minute intestinal fluke Haplorchis taichui (35.9%). Amplicon sequencing of 16S rRNA was conducted to investigate the gut microbiome profiles of H. taichui-infected participants compared with those of parasite-free participants. Prevotella copri was the dominant bacterial operational taxonomic unit (OTU) in the study population. The relative abundance of three bacterial taxa, Ruminococcus, Roseburia faecis and Veillonella parvula, was significantly increased in the H. taichui-infected group. Parasite-negative group had higher bacterial diversity (α diversity) than the H. taichui-positive group. In addition, a significant difference in bacterial community composition (β diversity) was found between the two groups. The results suggest that H. taichui infection impacts the gut microbiome profile by reducing bacterial diversity and altering bacterial community structure in the gastrointestinal tract.

Published: May 2020

AbstractThe metacestode of Echinococcus multilocularis is the etiological agent of alveolar echinococcosis. The metacestode stage used for research is maintained in rodents by serial passages. In order to determine whether cryopreservation of E. multilocularis metacestodes would be suitable for long-term maintenance and replace serial passages, isolates of different geographic origin were cryopreserved in 1984–1986. The aim of the current study was to test the viability of cryopreserved isolates following long-term cryopreservation (up to 35 years) and to determine the phylogenetic clades these isolates belonged to. Cryopreserved isolates were tested for viability in vitro and in vivo in gerbils. In vitro results of 5 isolates indicated protoscolex survival in 13 of 17 experiments (76%) and metacestode survival in 5 of 12 (42%) in vivo experiments. In vivo results showed ‘abortive lesions’ in 13 of the 36 animals, 15 were negative and 8 harboured proliferating metacestode tissue containing protoscoleces. Genetic analysis confirmed the isolates belonged to European, Asian and North-American clades. In conclusion, the results of the current study indicate that metacestodes of E. multilocularis are able to survive long-term cryopreservation. Therefore, cryopreservation is a suitable method for long-term storage of E. multilocularis metacestode isolates and reduces the number of experimental animals.
Remembering the past, enhancing the present and sharing the future: a qualitative study of the impact of film screenings in care home communities
Authors: Breckenridge Jenna P. , Kroll Thilo , Wylie Gavin , Salzberg Ana 
Published: May 2020

AbstractMany care home residents lack opportunities for meaningful activity and social connection, resulting in poor physical and emotional wellbeing. Providing residents with varied activities and social opportunities can improve their quality of life. In this paper, we examine the potential for film to provide a meaningful, social activity. The limited existing research on film in care homes has predominantly examined the use of film clips and materials in stimulating reminiscence for people with dementia. In this paper, we adopt a broader, trans-disciplinary perspective of film, drawing on evidence from Film Studies that shared spectatorship has social and emotional benefits for the viewer. We offer the first qualitative study of care home residents’ social, emotional and embodied engagement with feature-length film and identify the key benefits of film in this setting. We ran social film screenings in two Scottish care homes over six weeks. Underpinned by psycho-cinematic theory, we collected and analysed observational data alongside interviews with care home staff and discussion groups with residents. Our findings identified three ways in which film screenings benefit residents and supports social connection: prompting reminiscence; enhancing residents’ experiences in the present; and creating a shared future and intergenerational connections. The paper offers useful insights into the rich potential for film to enhance the care home community, facilitate social connectivity and promote resident wellbeing.
Migrant aged-care workers in Australia: do they have poorer-quality jobs than their locally born counterparts?
Authors: Charlesworth Sara , Isherwood Linda 
Published: May 2020

AbstractMigrants make up a significant and growing proportion of the aged-care workforce in Australia. Using data from the 2016 National Aged Care Workforce Census and Survey, we investigate employment conditions for Australian-born and overseas-born frontline workers working in residential and home-based aged care, focusing on two key poor job quality indicators. We find that migrant home care workers from non-English-speaking background (NESB) countries are the most likely to be employed on a casual basis and to report hours-related underemployment. Migrant residential care workers from English-speaking background (ESB) countries are more likely to be casual while NESB migrants are more likely to be underemployed. Controlling for a range of employment and socio-demographic characteristics, we find that being an NESB migrant is significantly associated with both casual status and underemployment. Generally, while this association lessens with years spent in Australia, exposure to casual employment is amplified over time for NESB migrants in the residential sector. Holding a temporary visa increased the likelihood of casual employment for residential care workers and underemployment for home care workers. Working for a for-profit employer was also associated with poorer job quality. Further policy shifts in Australia towards temporary migration and increased marketisation of aged care may impact on the working conditions of migrant aged-care workers.
Staging Discord: Nordic Corporatism in the European Conservation Year 1970
Authors: Notaker Hallvard 
Published: May 2020

AbstractThis article shows how corporatism in the Nordic countries helped shape the ‘ecological turn’ as governments and conservationist associations co-organised the Council of Europe's ‘European Conservation Year 1970’. The national programmes came to present highly diverging levels of discord, as this nascent policy field channeled challenges to the premise of economic growth. Cross-national comparisons highlight the importance of variations in the institutional maturity of environmental administrations as well as in the power afforded to industrial representatives. Danish, Swedish and Norwegian archival sources illuminate negotiations between governments and private associations, contributing to an in-depth analysis of a rarely researched transnational event.
Saving for retirement: rules of thumb

Published: May 2020

Abstract
Rules of thumb (RoTs) are proposed as a means of promoting higher levels of Defined Contribution (DC) pension saving and to help stimulate debate about the high and uncertain cost of pension provision, leading to the development of solutions. The Lifetime Pension Contribution (LPC) tells young people what pension contribution is required over a full working life to achieve a decent retirement income, calculated as 23% of average UK earnings. Another RoT is that each 1% of earnings provides a pension of 1.5% of earnings. Other RoTs show how costs vary by retirement age and if the saverʼs retirement planning is on track. The current high cost of pensions is partly due to low interest rates and the inefficiencies of the DC market, with inadequate bulk purchasing power and risk sharing. RoTs might help encourage higher employer contributions, either through automatic enrolment or on a voluntary basis.
Dicamba translocation in soybean and accumulation in seed
Authors: Zaccaro Maria Leticia M. , Norsworthy Jason K. , Brabham Chad B. 
Published: May 2020

AbstractThe dicamba-resistant cropping system was developed to be used as a tool to control multiple-resistant weed species, particularly Palmer amaranth (Amaranthus palmeri S. Watson). However, dicamba applications have resulted in off-target movement of the herbicide to susceptible neighboring vegetation, with frequent damage to non–dicamba resistant soybean [Glycine max (L.) Merr.]. Pod malformation and subsequent auxin-like injury to progeny is common when parent soybean plants are exposed to the herbicide post-flowering. Yet no publication to date has conveyed the presence of dicamba in seed. The objective of this study was to determine whether dicamba exists and at what quantities inside soybean seed following a low-dose exposure in the pod-filling stage using radiolabeled herbicide as a tracer. Non–dicamba resistant soybean plants were grown in the greenhouse until the pod-filling growth stage and then treated with 2.8 g ae ha−1 of dicamba (1/200 of the recommended rate of 560 g ae ha−1). Immediately afterward, [14C]dicamba (approximately 6.4 kBq per plant) was applied to the adaxial surface of one trifoliate leaf located in the midportion of each plant. The greatest amount of [14C]dicamba recovered was in seeds and in pods, and these plant parts accumulated 44% and 38% of the total absorbed, respectively. Chromatography results showed that the totality of the [14C]dicamba present in the soybean seeds was in the phytotoxic form, except for a single sample, in which one metabolite was detected (possibly 5-hydroxy dicamba). Precautions should be taken to avoid dicamba exposure to sensitive soybean fields, especially those dedicated to seed production, as this may result in low seed quality and symptomology on progeny plants.
