description: Natural selection favors the more successful individuals. This is the elementary premise that pervades common models of evolution. Under extreme conditions, however, the process may no longer be probabilistic. Those that meet certain conditions survive and may reproduce while others perish. By introducing the corresponding binary birth-death dynamics to spatial evolutionary games, we observe solutions that are fundamentally different from those reported previously based on imitation dynamics. Social dilemmas transform to collective enterprises, where the availability of free expansion ranges and limited exploitation possibilities dictates self-organized growth. Strategies that dominate are those that are collectively most apt in meeting the survival threshold, rather than those who succeed in exploiting others for unfair benefits. Revisiting Darwinian principles with the focus on survival rather than imitation thus reveals the most counterintuitive ways of reconciling cooperation with competition.

description: Interpretando i movimenti apocalittici del XX secolo, si evidenziano tre diverse mentalità: 1) una violenza ideologica con le stesse caratteristiche del millenarismo cristiano medioevale; 2) una sopportazione delle situazioni catastrofiche nella speranza di un'epoca migliore; 3) un desiderio di conoscenze non comuni, che porta a costituire gruppi elitari. Generalizzando si pensa che tutti i vari movimenti apocalittici siano frutto di una subcultura razionale. La mentalità apocalittica ha sempre avuto fasi in cui era molto attiva e fasi in cui non lo era. Nella Germania del XX secolo sono fiorite diverse dottrine e correnti di intellettuali legate a movimenti apocalittici.

description: Many processes, such as discrete event systems in engineering or population dynamics in biology, evolve in discrete space and continuous time. We consider the problem of optimal decision making in such discrete state and action space systems under partial observability. This places our work at the intersection of optimal filtering and optimal control. At the current state of research, a mathematical description for simultaneous decision making and filtering in continuous time with finite state and action spaces is still missing. In this paper, we give a mathematical description of a continuous-time partial observable Markov decision process (POMDP). By leveraging optimal filtering theory we derive a Hamilton-Jacobi-Bellman (HJB) type equation that characterizes the optimal solution. Using techniques from deep learning we approximately solve the resulting partial integro-differential equation. We present (i) an approach solving the decision problem offline by learning an approximation of the value function and (ii) an online algorithm which provides a solution in belief space using deep reinforcement learning. We show the applicability on a set of toy examples which pave the way for future methods providing solutions for high dimensional problems.
Geochemical and planetary dynamical views on the origin of Earth's atmosphere and oceans

description: Earth's volatile elements (H, C, and N) are essential to maintaining habitable conditions for metazoans and simpler life forms. However, identifying the sources (comets, meteorites, and trapped nebular gas) that supplied volatiles to Earth is not straightforward because secondary processes like mantle degassing, crustal recycling, and escape to space modified the composition of the atmosphere. Here, we review two complementary approaches to investigate the origin of Earth's atmosphere and oceans. The geochemical approach uses volatile element abundances and isotopic compositions to identify the possible contributors to the atmosphere and to disentangle the processes that shaped it. In that respect, noble gases (He, Ne, Ar, Kr, and Xe), elements that are chemically inert and possess several isotopes produced by radioactivity, play a critical role. The dynamical approach uses our knowledge of planetary dynamics to track volatile delivery to the Earth, starting with dust transport in the disk to planet-building processes. The main conclusion is that Earth acquired most of its major volatile elements by accretion of planetesimals or embryos akin to volatile-rich meteorites. At the same time, solar/meteoritic noble gases were captured by embryos and some gases were lost to space, by hydrodynamic escape and large impacts. Comets did not contribute much H, C, and N but may have delivered significant noble gases, which could represent the only fingerprints of the bombardment of our planet with icy bodies. The processes that governed the delivery of volatile elements to the Earth are thought to be relatively common and it is likely that Earth-like planets covered with oceans exist in extra-solar systems.

description: The management of electronic resources (ERs) has become a core function of academic libraries and researchers have revealed how academic libraries in developed countries are struggling to successfully manage these resources. The scholarly literature on the management of ERs in libraries has predominantly focused on developed country context. Little research has been conducted on how academic libraries in developing countries are managing their online databases. This paper presents the findings of a study that examines ER workflows and the extent to which ER workflows or the practices of managing online databases in academic libraries in Ghana compare with the Techniques of Electronic Resource Management (TERMS) framework. Data were collected from library staff in two public and two private universities, and consortium executives using semi-structured interviews. The findings revealed that although efforts had been made to follow standard procedures, some components of the TERMS framework were absent in the ER workflow in both public and private case libraries while other aspects of the workflow were responsibilities of parties external to the libraries. Opportunities exist for improving ERM practices in academic libraries in Ghana. In particular, by involving users in the selection and assessment of ERs, increasing promotional activities, and improving the documentation of ER workflow. The findings also revealed interconnections between various stages of TERMS. The findings provide a basis from which academic libraries can improve their practices and extends the application and revision of the TERMS framework to an African context.

description: A position-sensitive, high-resolution time-of-flight detector for fission fragments has been developed. The SPectrometer for Ion DEterminiation in fission Research (SPIDER) is a $2E-2v$ spectrometer designed to measure the mass of light fission fragments to a single mass unit. The time pick-off detector pairs to be used in SPIDER have been tested with $α$-particles from $^{229}$Th and its decay chain and $α$-particles and spontaneous fission fragments from $^{252}$Cf. Each detector module is comprised of a thin electron conversion foil, electrostatic mirror, microchannel plates, and delay-line anodes. Particle trajectories on the order of 700 mm are determined accurately to within 0.7 mm. Flight times on the order of 70 ns were measured with 200 ps resolution FWHM. Computed particle velocities are accurate to within 0.06 mm/ns corresponding to precision of 0.5%. An ionization chamber capable of 400 keV energy resolution coupled with the velocity measurements described here will pave the way for modestly efficient measurements of light fission fragments with unit mass resolution.

description: Purpose: This research examines the ways in which museums have utilised their Facebook platforms to communicate about climate and environmental-related challenges. The aim is to offer a snapshot of the phenomenon of museums as contributors to communicating climate-related topics and climate change education. Design/methodology/approach: A content analysis of a purposeful sample of 10 museums’ Facebook postings was conducted. The study examines the themes and topics concerning climate issues that museums have posted and communicated about, the nature of the communication and an examination of responses from the audience. Findings: This research reveals that not all museums in the study sample have communicated the different research-informed causes or contributors to climate challenges confronting societies today. There is also very little evidence of dialogic engagement with audience and the public-at-large. Most communication is still one-way focussing on the relaying of information. Originality/value: This research highlights the roles of cultural heritage institutions such as museums in communicating climate change-related topics and the need to move towards a more dialogic mode of engagement with their audience. Museums have a role in serving as a trusted and inspirational space for public debates and community empowerment for dealing with climate challenges.

description: Quenched disorder affects significantly the behavior of phase transitions. The Imry-Ma-Aizenman-Wehr-Berker argument prohibits first-order or discontinuous transitions and their concomitant phase coexistence in low-dimensional equilibrium systems in the presence of random fields. Instead, discontinuous transitions become rounded or even continuous once disorder is introduced. Here we show that phase coexistence and first-order phase transitions are also precluded in nonequilibrium low-dimensional systems with quenched disorder: discontinuous transitions in two-dimensional systems with absorbing states become continuous in the presence of quenched disorder. We also study the universal features of this disorder-induced criticality and find them to be compatible with the universality class of the directed percolation with quenched disorder. Thus, we conclude that first-order transitions do not exist in low-dimensional disordered systems, not even in genuinely nonequilibrium systems with absorbing states.

description: Electronic resources (ERs) in academic libraries have become a global phenomenon due to technological developments, and these resources are changing the expectations of library users as well as the nature of the work of librarians. Although there is an extensive body of literature on the management and usage of ERs in academic institutions, few researchers have taken a holistic view by studying both concepts in a single study to reveal how they are related. Previous studies have investigated only the management or usage of ERs as separate concepts. This study investigates the management and usage of ERs in academic libraries in Ghana to explore the connection between the two concepts. The aim is to provide better recommendations for practice. This research applied a mixed methods design. Twenty-four library staff and three library consortium executives were interviewed. Faculty members and postgraduate students from four institutions were surveyed. Our findings show the various ways in which the management and usage of ERs have an influence on each other. These were mainly in the areas of selection, access provision, publicity, training, evaluation, and usage of ERs. The importance of appropriate and adequate resourcing, the marketing and demonstration of the value of ERs, training and usage evaluation are discussed.

description: We investigate ground states of $s$=1/2 Heisenberg antiferromagnets on the eleven two-dimensional (2D) Archimedian lattices by using the coupled cluster method. Magnetic interactions and quantum fluctuations play against each other subtly in 2D quantum magnets and the magnetic ordering is thus sensitive to the features of lattice topology. Archimedean lattices are those lattices that have 2D arrangements of regular polygons and they often build the underlying magnetic lattices of insulating quasi-two-dimensional quantum magnetic materials. Hence they allow a systematic study of the relationship between lattice topology and magnetic ordering. We find that the Archimedian lattices fall into three groups: those with semiclassical magnetic ground-state long-range order, those with a magnetically disordered (cooperative quantum paramagnetic) ground state, and those with a fragile magnetic order. The most relevant parameters affecting the magnetic ordering are the coordination number and the degree of frustration present.

description: Purpose: While memory institutions' use of social media has proliferated, research and scholarly literature on risks, resulting from social media use, memory institutions' social media risk-aware culture and, in particular, social media risk management remains scant. This study addresses this knowledge gap and identifies aspects of social media risk management from other sectors that could inform the cultural heritage sector. Design/methodology/approach: This research involves a review of the scholarly and professional literature that contribute to social media risk management discourses. These include those that discuss the different categories of social media risks, social media policies, risk-aware culture and social media risk management strategies and processes. Works discussing social media risk management models and frameworks are also included in the review. Based on the insights gained from these reviews, a pillar framework to guide social media risk management in memory institutions is developed. Findings: The proposed framework outlines the baseline components relevant for the cultural heritage sector and underlines the evolving and continual nature of these components. Elements particularly important to memory institutions are highlighted. Notably, that social risks as a risk category must be recognised. Also noted is that the conventional apolitical stance still taken by many memory institutions need to be reviewed. The importance of memory institutions to be not overly risk-averse to the point of failing to take advantage of the affordances of social media platforms, thereby stifling potential innovations around services and engagement with their users/audience is discussed. Originality/value: This research offers an extensive review of the social media risk management literature, both scholarly and professional across different domains. The ensuing insights inform the development of a pillar framework to guide social media risk management in memory institutions. The framework outlines a baseline mapping of the governance, processes and systems components. The expectation is that this framework could be extended to account for contextual and situational requirements at more granular levels to reflect the nuances, variances and complexities that exist among different types of memory institutions and to account for varying attributes, mandates and priorities in the cultural heritage sector.

description: We propose a theory of the thermal Casimir interaction for multilayered test bodies coated with a graphene sheet. The reflection coefficients on such structures are expressed in terms of the components of the polarization tensor and the dielectric permittivities of material layers. The developed theory is applied to calculate the gradient of the Casimir force between an Au-coated sphere and a graphene sheet deposited on a SiO${}_2$ film covering a Si plate, which is the configuration of a recent experiment performed by means of a dynamic atomic force microscope. The theoretical results are found to be in very good agreement with the experimental data. We thus confirm that graphene influences the Casimir interaction and can be used for tailoring the force magnitude in nanostructures.

description: Let $\mathcal{P}$ be a partition of a finite set $X$. We say that a full transformation $f:X\to X$ preserves (or stabilizes) the partition $\mathcal{P}$ if for all $P\in \mathcal{P}$ there exists $Q\in \mathcal{P}$ such that $Pf\subseteq Q$. Let $T(X,\mathcal{P})$ denote the semigroup of all full transformations of $X$ that preserve the partition $\mathcal{P}$. In 2005 Huisheng found an upper bound for the minimum size of the generating sets of $T(X,\mathcal{P})$, when $\mathcal{P}$ is a partition in which all of its parts have the same size. In addition, Huisheng conjectured that his bound was exact. In 2009 the first and last authors used representation theory to completely solve Hisheng's conjecture. The goal of this paper is to solve the much more complex problem of finding the minimum size of the generating sets of $T(X,\mathcal{P})$, when $\mathcal{P}$ is an arbitrary partition. Again we use representation theory to find the minimum number of elements needed to generate the wreath product of finitely many symmetric groups, and then use this result to solve the problem. The paper ends with a number of problems for experts in group and semigroup theories.

description: How public library policies, practices and services support the information needs of people experiencing homelessness was investigated using a qualitative-phenomenological design. Data were collected through semi-structured, face-to-face interviews with four homeless participants and seven librarians from four public library networks from a particular New Zealand region. The findings revealed that while none of the participating libraries had policies or services that were targeted at homelessness individuals, the libraries were perceived as providing services that largely met the information needs of their homeless patrons even if there were areas for improvement. It was noted that libraries could provide services that contribute to the strengthening of cultural identity and that policies and services should take relevant socio-cultural contexts into consideration. The findings inform public library policies and practices so that services could be developed and improved in order to enable equitable and effective use by homeless individuals, without unnecessarily segregating this user group.

description: Purpose: The purpose of this study is to propose a set of design recommendations for crowdsourcing platforms with a focus on user engagement. A sample of New Zealand (NZ) cultural heritage institutions (CHIs) crowdsourcing platforms were assessed, with the aim of offering insights into how they have been designed to encourage dialogue and engagement and to sustain participation. Design/methodology/approach: The design recommendations were derived from a review of related works. Following this, 12 crowdsourcing projects overseen by libraries, museums and an archive in NZ were assessed against the recommendations through content analysis. Findings: The recommendations were classified into four main categories. These were promote ease of use, attract and sustain user interest, foster a community of users and show users that their work is contributing to the institution and society. The findings indicated that the sample of crowdsourcing projects assessed were generally successful at displaying the credibility and significance of their projects, and promoting their crowdsourced collections. Many of the projects could nevertheless benefit from providing further support to promoting dialogues and engagement with their users and contributors and sustaining offline community interaction. Research limitations/implications: The content analysis conducted was focused on the functionality of design elements of the crowdsourcing platforms. The design recommendations derived from the analysis were intended as a starting point for discussion and they would need to be validated in further studies. Other relevant project information such as funding and staffing, promotion and outreach efforts were not solicited in this study. Such information could provide important contextualisation. Future research could take the form of in-depth case studies, including surveying those involved in the projects and stakeholders to investigate such contextual aspects of crowdsourcing projects. Originality/value: Previous research on crowdsourcing in NZ CHIs consisted of single case studies. This study provides a wider snapshot and insights into digital crowdsourcing platforms from public NZ CHIs. The study findings have practical implications for project managers and Web designers involved in crowdsourcing projects, particularly those in the cultural heritage sector.

title: Il messianismo nella storia del cristianesimo. Aspetti e problemi

description: Se si scorre l'ampia bibliografia relativa al messianismo e ai messianismi nella storia del cristianesimo, si è colpiti da una duplice constatazione. Per un verso, sotto questa etichetta di comodo è possibile ritrovare fenomeni molto eterogenei, che uno sguardo dall'alto fatica a ricondurre nello stesso campo concettuale. Per un altro, lavori che si occupano da un punto di vista storico del messianismo cristiano sul lungo periodo sono pressoché assenti: a differenza di quanto è successo per il messianismo ebraico, manca a tutt'oggi una vera e propria storia del messianismo cristiano. Se queste due affermazioni sono esatte, ne consegue una domanda inevitabile, che fa da sfondo alle considerazioni che seguono: come mai, nonostante una tale abbondanza di libri sul messianismo cristiano, non esiste una sua storia?

description: We report a method to determine propagation delays of optical 10 Gb/s data traveling through a 75 km long amplified fiber link with an uncertainty of 4 ps. The one-way propagation delay is determined by two-way exchange and cross correlation of short (< 1 ms) bursts of 10 Gb/s data, with a single-shot time resolution better than 2.5 ps. We thus achieve a novel optical communications link suited for both long-haul high-capacity data transfer and time transfer with picosecond-range uncertainty. This opens up the perspective of synchronized optical telecommunication networks allowing picosecond-range time distribution and millimeter-range positioning.

description: Scholarly investigations into the extent and nature of schools and public libraries collaborating in the “maker/making” space are scant. This research sets out to address this knowledge gap, by investigating the perspectives of public libraries’ staff: How public libraries and schools have worked together on makerspaces and “making” programmes, the motivations for and the nature of collaborations, and challenges that need addressing for successful collaborations, and their perceived outcomes of such collaborations. This study shows how through collaborating with schools, public libraries can make meaningful contributions to social and digital inclusion in their communities, fulfilling their roles as social institutions. Our findings highlight the importance of contextual flexibility to be considered in such collaborations, with partnering organizations negotiating a suitable model for working together. The roles and contributions of each party involved could be considered across spectrums of engagement, planning, resource-sharing, and activities, depending on the contextual needs, priorities, and requirements of the partnering institutions. We discuss how these can be achieved through dialogic communication for sustained partnerships.

description: This paper investigates how Māori secondary school students aged 16–18 years engage with information to assist them in making decisions about their future career options. Little has been written about how Māori access information and this article fi lls a gap in the literature. Research was undertaken in four secondary schools, using a questionnaire and focus group sessions. Of the 139 participants, approximately two thirds (94) had made a decision about their future career. The results of the questionnaire demonstrate a heavy reliance on interpersonal sources rather than electronic and printed resources. The people they seek information from are either friends, close whänau members or individuals that are working in careers they are interested in. Participants identified several barriers to getting the information they require including not knowing who to ask, not wanting to ask other people, people asked not always knowing how to help, and being overwhelmed by how much information is available.

description: This article reports on a research project that investigated whether New Zealand public library websites reflect New Zealand’s Māori/bicultural heritage. Each website was assessed using a bicultural evaluation tool consisting of nine criteria. The results of the evaluation reveal that although there are a small number of libraries achieving at a high level, the majority of websites have very low levels of Māori/bicultural content available.
