Digital Campus Culture: Diversity, Inclusivity and Social Media
Authors: Goode Luke , Woodward Suzanne
Published: June 2018

Social media platforms provide environments in which students from diverse backgrounds socialise, debate and share knowledge. At the same time, the value of such environments can be undermined by various forms of aggression and bigotry. Problems of online bullying, harassment and incivility present particular challenges for universities striving to foster an environment that is welcoming, inclusive and respectful. A range of official and unofficial online environments have become extensions of institutional culture, yet they cannot be regulated in the same manner as physical campus environments. This paper examines ways in which modes of racism, sexism and other forms of prejudice are propagated, normalised and sometimes challenged within universities' social media spaces. These groups show a marked difference in levels of debate and interpersonal engagement, such that in some cases, instances of racism, sexism and homophobia can lead to critical deliberation, while in others such bigotry goes unchecked.
Facebook as a Platform for an Imagined Diasporic Community
Authors: Ray Paula
Published: June 2018

Overcoming geographically determined territorial boundaries, Facebook as a communication platform offers an extension of Benedict Anderson’s concept of the ‘imagined community’ (2006, xi), particularly in the form of groups formed around diasporic communities. These Facebook groups encourage civic engagement and are bound together by the use of a distinctive ‘cyber-language’ and set of expressions that contribute to a sense of shared identity. In this paper, I look at the ‘cyber-dialogues’ of three south Asian diasporic cultures in New Zealand, namely Indian, Malaysian and Filipino, to identify the most popular civic issues raised on this platform by each of them.
The Holy Trail: Rethinking ‘Value’ in Google’s Ubiquitous Mapping Project
Authors: Kuehn Kathleen , Daubs Michael
Published: June 2018

This research explores issues of convergence, value and labour through a case study of the Google ‘Trekker’ programme: a crowdsourcing initiative in which volunteers carry camera-outfitted ‘trekker packs’ to capture remote or hard to reach landscape imagery for Google Maps. We theorise how ‘ubiquitous mapping’ redefines traditional spatial boundaries, and how these new forms of convergence redefine notions of value around both labour and cultural space. Simultaneously physical and virtual, manual and digital, material and immaterial, Google Trekkers voluntarily produce immaterial goods via manual processes, problematising existing critiques around the social relations of production. From this context, we discuss how Google Trekker expands the company’s commercial value at the expense of consumer and citizen privacy, while retaining control over the construction and meaning of space.
Lacan, Laclau, and the Impossibility of Free Trade
Authors: Owen Thomas
Published: June 2018

This paper applies Lacan’s ‘negative ontology’ to mediated representations of ‘free trade’, and, in particular, the intellectual property aspects of free trade agreements. More specifically, the paper adopts Lacan’s conception of the ‘Real’ as radically inaccessible, and Laclau’s conception of discourses as contingent and always-already dislocated, to examine how the mediated objects of ‘free trade’ and intellectual property are unfixed, paradoxical, and perpetually haunted by their negative outsides. Free trade agreements and intellectual property protections are key nodal points in contemporary political economy.  However, the historic elaboration of ‘free trade’ reveals the internal incoherence of an object experiencing continued rupture, suture, and contingent impossibility.  This paper deploys a historico-contextual analysis of patent protection and free trade agreements to illustrate such contingency.  It then compares Lacanian negative ontology to the positive realism of mainstream journalism, argues such realism is ill-equipped to accurately capture contingency, and, finally, suggests alternative ways journalism may engage with negatively constituted social phenomena.
‘Death to Videodrome’: Cronenberg, Žižek and an Ontology of the Real
Authors: Wilson Scott
Published: June 2018

The closing frames of David Cronenberg’s Videodrome (1983) show us the protagonist, Max Renn, seemingly in the act of suicide, his mutated flesh-hand-pistol pressed firmly against his head. Looking directly at us, Max utters the phrase ‘long live the new flesh’ before the film fades to black. This act ends the film, but the end of the film, despite this seemingly conclusive moment, might not mark the end of Max’s experience of the diegesis. In a film concerned with bodily transformation in response to media intervention, a film in which our heterosexual male protagonist develops a vaginal opening which generates and transforms objects subject to its own desires and agency, what are we to make of this film’s ending (and other similar moments in Cronenberg’s work)? What if the vaginal slit that appears in Max’s abdomen during the film opens not into his bodily interior but, instead, into a new ontology – the ontology of the Real? What if Videodrome ends not with Max’s death but with his movement beyond the Symbolic and into the Real, beyond signification, beyond ontology?This paper seeks to explore a select number of Cronenberg’s mid-period works in relation to what Slavoj Žižek refers to as the pre-ontological, a realm of signification that elsewhere links to the abject but which, equally, might provide a glimpse of the unsettling Real that so many of Cronenberg’s protagonists hurtle powerlessly towards and which lurks just outside the frame of his narratives, hinted at but always escaping our standard ontological practices.
Epochality, Temporality and Media-Communication Ownership in Aotearoa-New Zealand
Authors: Hope Wayne
Published: June 2018

Amidst academic policy debates over the proposed Fairfax-NZME and Sky-Vodafone mergers, the historical patterns of media-communication ownership received little mention. The purpose of this article is to explain, firstly, how the very possibility of such mergers eventuated and, secondly, why associated epochal reconfigurations in the political economy of New Zealand capitalism eluded public depiction. Initially I examine the repercussions which arose from: the restructuring of Radio New Zealand and Television New Zealand into State-Owned Enterprises (1987); the arrival of TV3 (1989); the formation of pay-subscription Sky Television (1990); and the abolition of all legal restrictions on foreign media ownership (1991). Together these events signalled the hollowing out of New Zealand’s media-communication system and the unfolding ownership patterns of conglomeration, transnationalisation and financialisation. Behind this critical narrative, I explore how the simultaneous restructuring of the national political economy, mediated public life and the vocabulary of economics obfuscated the epochal shift that was taking place. An ongoing lack of public awareness about this shift has debilitated normatively-grounded critiques of the contemporary media landscape and the ownership patterns which came to prevail.
The Rise of Tactical Partnerships: Media Converging Beyond Ownership
Authors: Myllylahti Merja
Published: June 2018

This qualitative research article explores New Zealand media convergence in an increasingly digital media environment. It considers media ownership convergence in the context of the Commerce Commission’s merger rulings in 2017. However, the focus of the research is on other kind of convergences. There is a lack in New Zealand academia of research in this field, and this article aims to help fill the gap. The research maps evolving convergences within New Zealand media sector by utilising Rick Gordon’s (2003) concepts of convergences as its analytical framework. It utilises document analysis method, and the primary data is collected from academic reports, corporate and government documents and news articles. The article finds that beyond ownership convergence, tactical and structural convergences are rapidly expanding in New Zealand media sector, and these arrangements may well expand as the Commerce Commission has denied major mergers. Content-sharing between media organisations has become more common because of the increasing importance of audience size and website traffic.
Distorted Direction: A Critique of the Convergence Agenda in Media Policy Renewal
Authors: McEwan Rufus
Published: June 2018

In August 2015, a New Zealand Government discussion paper entitled Exploring Digital Convergence was released with the stated aim of generating public debate regarding the implications of digital convergence and any prospective government response. At face value, this convergence discussion offered a vital opportunity for a review of New Zealand media and communications policy that follows international precedent. While it is readily accepted that established media structures are being confronted with growing uncertainty and the formation of new media practices invites a regulatory response, this paper is critical of the specific application of convergence in the reimagining of media policy. Despite popular currency, convergence remains a highly contentious subject in media scholarship, open to diverse interpretation. Using official government documents, public submissions and in-depth interviews with broadcast industry stakeholders, this article provides a critical examination of convergence discussion in New Zealand. Consequently, this paper argues that a convergence approach to media regulation is constrained by the assumptive logic and contested meaning of the concept and not conducive to establishing meaningful reform for New Zealand’s unique media landscape.
Diversity in Reporting? A Study of the News coverage of the 2016 New Zealand Local Body Elections
Authors: Baker Sarah , Owen Thomas , Rupar Verica , Myllylahti Merja , Devadas Vijay , Craig Geoffrey , Berti Carlo
Published: June 2018

This study offers an analysis of print news media coverage of the 2016 New Zealand Local Body elections, focusing on reportage around issues of diversity. This study builds upon a prior project by the Media Observatory group at Auckland University of Technology of the 2014 New Zealand General election that also examined issues of diversity. The function of news media in democratic societies is crucial.  For a nation-state that is as cosmopolitan and diverse as New Zealand, issues of inclusivity and representation are critical considerations for news media. This study employs content analysis and examined news coverage of local body elections and analysed 198 Local Elections newspaper articles from the eight weeks prior to 8 October 2016 in one nationwide newspaper and four Auckland community newspapers. It focuses on The New Zealand Herald, East & Bays Courier, Manukau Courier, North Shore Times, Central Leader and the Western Leader. The analysis of the 2016 Local Election news coverage demonstrates a predominant focus on the mayoral candidates to the detriment of other aspects of local election voting, and a focus on campaign strategy over social issues impacting the electorate. The Local Election coverage placed particularly strong focus on “youth” as a social group in contrast to other classified groups such as Māori, Asians, Pacific Islanders, the elderly, and dependents. The Local Election coverage also represented a diversity of social issues, from housing, transport, to business and economy, environment, and law and order. The coverage provided ample space for words and perspectives from the electoral front-runners, local government representatives, and for public voices but it also paid minimal attention to non-mayoral voting categories, non-front runner candidates, and non-Auckland geographical locations, although this latter point was perhaps unsurprising, given the newspapers sampled in the study.
The Media We Want By 2020
Authors: Ellis Gavin
Published: June 2018

A period as short as three years will not produce fundamental change to New Zealand’s news media landscape but there is scope for positive improvement within a version of the status quo. Media – and the workings of democracy – would be improved by market reform, greater co-operation in news-gathering, and comprehensive multimedia regulation that protects citizens’ rights. However, for mainstream media to fully serve their democratic function they must urgently institute measures to regain the public’s trust.
New Land, New Opportunities, New Language: Māori Television and Migrants Learning Te Reo
Authors: Nemec Susan
Published: June 2018

Te reo Māori is one of the official languages of New Zealand. Many migrants from non-English speaking nations, however, are surprised at the monolingualism of New Zealand and the apparent tokenism in use of te reo. Often migrants arrive ready to acquire a level of te reo Māori because of their own multilingual background. This paper explores the extent to which Māori Television provides cultural resources for migrants to increase te reo skills and vocabulary and to engender an interest for further engagement with te reo Māori, and suggests that engaging in learning te reo contributes to Māori Television’s language revitalisation outcomes. Improved understanding of the distinctive use of te reo Māori within the everyday lexicon of New Zealand English contributed to a sense of belonging for many of the participants.  All of these findings suggest the level of support migrants can offer Māori language revitalisation initiatives may be unrecognised.
The Dub Encounter in New Zealand Film
Authors: Wright Alan
Published: June 2018

Peter Wells takes ‘dubbing’ as a metaphor to describe the cultural and cinematic experience of projecting ‘our thoughts, desires and dreams … into other peoples’ accents’ (2005, 25). Only when ‘the element of dubbing is removed from our speech on film’ will New Zealand cinema find its own voice. I use the idea of dubbing to advance a theoretical reading of New Zealand film that undoes the binary between local and global. I explore this unheimlich quality in reference to the films of John O’Shea, Barry Barclay and Florian Habicht. I examine the rupture that these directors introduce between voice and image in order to discover a poetics of identity that is attuned to a disjunct experience of place, time and history beyond the limits of national cinema.
Framing the Border: Securing Mobility and Representing the Nation
Authors: Anderson Rachael
Published: June 2018

Airports are spaces where mobility is experienced in a number of ways. Often described as a non-place (Augé 1995) where anonymous individuals circulate, the airport also operates as a site of national security where all passengers must be identified. International airports in New Zealand, as gateways to an island nation, offer a compelling site for analysing the ways in which movement across the border is regulated. Media representations of passenger movement through Wellington International Airport and Auckland International Airport produce particular conceptions of citizenship and national identity. This paper will discuss how media discourses surrounding Wellington and Auckland airports position passengers in particular ways in relation to the nation, focusing on the representation of passenger movements which interpellate both New Zealand citizens and foreigners alike.
Enhanced temperature and light stability of amorphous indium-gallium-zinc oxide thin film transistors by interface nitrogen doping
Authors: Huang Xiaoming , Zhou Dong , Xu Weizong , Wang Yongjin
Published: June 2018

The electrical characteristics of amorphous indium-gallium-zinc oxide (a-IGZO) thin film transistors (TFTs) with an ultrathin nitrogenated a-IGZO (a-IGZO:N) layer embedded at the channel/gate dielectric interface are investigated under positive gate-bias stress temperature (PBST) and negative bias illumination stress (NBIS). The devices with a-IGZO:N layer show enhanced electrical stability, with significantly reduced threshold voltage shift. Meanwhile, it is found that the average effective energy barrier for the positive gate-bias stress process in the TFTs with a-IGZO:N layer increases, which causes fewer channel carriers trapped in the channel/gate dielectric interface or insulator. According to x-ray photoelectron spectroscopy analyses, the concentration of oxygen vacancies (OV) is reduced when nitrogen is incorporated into the a-IGZO films. Therefore, the improved electrical stability of the a-IGZO TFTs upon PBST and NBIS is attributed to the reduction of interface OV-related defects by nitrogen doping.
A theoretical model of fuselage pressure levels due to fan tones radiated from the intake of an installed turbofan aero-engine
Authors: Gaffney James , McAlpine Alan , Kingan Michael J.
Published: June 2018

An existing theoretical model to predict the pressure levels on an aircraft's fuselage is improved by incorporating a more physically realistic method to predict fan tone radiation from the intake of an installed turbofan aero-engine. Such a model can be used as part of a method to assess cabin noise. Fan tone radiation from a turbofan intake is modelled using the exact solution for the radiated pressure from a spinning mode exiting a semi-infinite cylindrical duct immersed in a uniform flow. This approach for a spinning duct mode incorporates scattering/diffraction by the intake lip, enabling predictions of the radiated pressure valid in both the forward and aft directions. The aircraft's fuselage is represented by an infinitely long, rigid cylinder. There is uniform flow aligned with the cylinder, except close to the cylinder's surface where there is a constant-thickness boundary layer. In addition to single mode calculations it is shown how the model may be used to rapidly calculate a multi-mode incoherent radiation from the engine intake. Illustrative results are presented which demonstrate the relative importance of boundary-layer shielding both upstream and downstream of the source, as well as examples of the fuselage pressure levels due to a multi-mode tonal source at high Helmholtz number.

A missing link in cholesterol absorption

Cholesterol is important for general health, but too much can build up in artery walls and cause cardiovascular disease. Low-density lipoprotein cholesterol (LDL-C) is often referred to as “bad cholesterol”; keeping LDL-C within stringent limits is recommended to reduce the risk of heart attack and stroke. Zhang
et al.
discovered that some individuals have an inherited frameshift mutation in the
LIMA1
gene (also known as
EPLIN
or
SREBP3
). The gene has not been linked to lipid metabolism before, but altered
LIMA1
was found to maintain low plasma LDL-C by reducing the absorption of cholesterol through the intestine. Pharmacological targeting through the LIMA1 pathway might thus provide a strategy to improve heart health.

A tetrapod fauna from within the Devonian Antarctic Circle
Authors: Gess Robert , Ahlberg Per Erik
Published: June 2018

Out of Antarctica

When we think of Devonian tetrapods, the ancestors of all modern vertebrates, we tend to picture amphibian-like creatures emerging from the water into a wet tropical forest or swamp. Indeed, all previously described specimens of this group have been recovered from the tropics. Gess and Ahlberg now describe two fossil tetrapods from Devonian Antarctica. Thus, the distribution of tetrapods may have been global, which encourages us to rethink the environments in which this important group was shaped.

Published: June 2018

Target degradation of Type I CRISPR

The CRISPR adaptive immune systems defend bacteria against invaders. Type I CRISPR-Cas systems, the most prevalent type, use a Cascade complex to search the target DNA that is then degraded by Cas3 protein. Xiao
et al.
report cryo–electron microscopy structures of the Type I-E Cascade/Cas3 complex in the pre– and post–DNA-nicking states. These structures reveal how Cas3 captures Cascade only in its correct conformation to reduce off-targeting and how Cas3 switches from the initial DNA-nicking mode to the processive DNA degradation mode.

Prospective observational study of point-of-care ultrasound for diagnosing pneumonia
Authors: Lissaman Claire , Kanjanauptom Panida , Ong Cyril , Tessaro Mark , Long Elliot , O’Brien Adam
Published: June 2018

Objectives

The clinical diagnosis of pneumonia lacks specificity and may lead to antibiotic overuse, whereas radiological diagnoses can lack sensitivity. Point-of-care lung ultrasound is an emerging diagnostic tool. There are limited prospective data, however, on the accuracy of sonologists in the paediatric emergency department setting. We aimed to test the diagnostic accuracy of lung ultrasound for pneumonia using chest radiograph (CR) as the reference standard.

Methods

This prospective observational cohort study in a paediatric emergency department enrolled children aged 1 month to <18 years, who had a CR ordered for possible pneumonia. Lung ultrasounds were performed by two blinded sonologists with focused training. Sonographic pneumonia was defined as lung consolidation with air bronchograms. Radiograph and ultrasound results both required agreement between two readers, with final results determined by an arbiter in cases of disagreement. Patient management was decided by treating clinicians who were blinded to lung ultrasound results. Follow-up was performed by phone and medical record review to obtain final diagnosis and antibiotic use.

Results

Of 97 included patients, CR was positive for pneumonia in 44/97 (45%) and lung ultrasound was positive in 57/97 (59%). Ultrasound sensitivity was 91% (95% CI 78% to 98%) and specificity was 68% (95% CI 54% to 80%). Ultrasound results displayed greater consistency with CR and patient outcomes when sonographic consolidation exceeded 1 cm. Thirteen of 57 patients with sonographic consolidation improved without antibiotics.

Conclusion

Lung ultrasound may have a role as first-line imaging in patients with possible pneumonia, with higher specificity for consolidations exceeding 1 cm.

Peribiliary cysts: a systematic review and proposal of a classification framework
Authors: Bazerbachi Fateh , Haffar Samir , Sugihara Takaaki , Mounajjed Taofic M , Takahashi Naoki , Murad Mohammad Hassan , Abu Dayyeh Barham K
Published: June 2018

Objective

Peribiliary cysts are usually benign, although severe complications and mortality may occur, and they may be confounded with other diseases. No classification delineating their different characteristics exists.

Design

We performed a systematic review of the frequency and clinical manifestations of peribiliary cysts. Two reviewers identified studies after searching multiple databases on 2 August 2017.

Results

These cysts were prevalent in cirrhosis (9%). A total of 135 patients were reported in 72 papers with sufficient clinical data (10 countries, 65% from Japan, median age 63 years (range: 4–88), and 80% were males). Symptoms were present in 70%. Misdiagnosis occurred in 40%, and 33% underwent therapeutic misadventures. Cysts were solitary in 10%. Obstructive features and cholangitis were observed in 36% and 12.5%, respectively. Cysts progression was observed in 37.5% over a median of 18 months. Mortality was 24%, mostly due to cirrhosis. A classification framework is proposed, wherein type I includes hepatic, type II extrahepatic and type III mixed hepatic and extrahepatic cysts, each having distinct features. Specifically, type II was more frequent in females, solitary, without cirrhosis, presenting with obstructive jaundice, more difficult to diagnose and required more surgical interventions (all p<0.05).

Conclusion

Although rarely studied in the literature, peribiliary cysts were frequent in studies designed to evaluate their prevalence, and were mostly asymptomatic. Inaccurate diagnosis, therapeutic misadventures, cysts progression and cysts-related complications are frequent. In a novel classification framework based on location, extrahepatic peribiliary cysts have distinct characteristics and require a special approach for diagnosis and management.
Accidentally-on-purpose: findings from a qualitative study exploring pregnancy intention and long-acting reversible contraceptive use
Authors: Coombe Jacqueline , Harris Melissa L , Loxton Deborah
Published: June 2018

Background

Although it is known that pregnancy intention impacts contraceptive use, there has been little exploration into the relationship between pregnancy intention and long-acting reversible contraception (LARC) non-use in the Australian context.

Methods

Semi-structured telephone interviews with a sample of participants from the Contraceptive Use, Pregnancy Intention and Decisions (CUPID) Study were conducted in 2016.

Results

Of the 59 women contacted, 15 participated in an interview. One theme arising from these interviews is reported here. Results from the analysis suggest that women with ambivalent or unclear plans toward pregnancy were less likely to perceive LARC as a suitable method for them. Conversely, women who clearly intended to avoid pregnancy and who had clear plans for future pregnancy valued these methods, and often framed their future plans for pregnancy within the context of their chosen LARC.

Conclusions

Findings presented demonstrated the complex relationship between pregnancy intention and contraceptive use. In particular, this study provided insight into the complex notion of pregnancy ambivalence. Dichotomous definitions of pregnancy as intended or unintended were found to be inadequate in encapsulating actual reproductive experiences.
Vibrational studies, quantum chemical calculations, and molecular modelling of ferrous fumarate
Authors: Justin P. , Devi R. Niranjana , Anitha K.
Published: June 2018

Ferrous fumarate, an excellent pharmaceutical drug, was investigated theoretically, which was found to be in accordance with experimental results. FT-Raman and FT-IR spectra were recorded and effectively correlated with computed vibrational studies. DFT/B3PW91 method using 6–311G basis set was employed to determine the optimized structure of ferrous fumarate. Consecutive vibrational modes have been assigned and the calculated structural parameters were compatible with the experimental results. Ionization energy was found to be very low (0.263 eV), thereby the hardness analysis confirms the ferrous fumarate is soft (13.872 eV). Frontier molecular orbital theory confirms the low stability of the molecule. Molecular electrostatic potential map (MEP) shows the nucleophilic and electrophilic sites, which favour the possible reactive sites for future ligand attachments. Molecular docking studies of ferrous fumarate against harmful fungal pathogens and hemoglobin variants aids in the detection of effective binding modes of receptor–ligand complex, which lead towards novel drug discovery.

Des calculs de théorie de la fonctionnelle de la densité (DFT) ont été effectués pour obtenir des géométries optimisées, les énergies orbitales moléculaires occupées les plus basses (HOMO), les énergies des orbitales moléculaires inoccupée les plus basses (LUMO), les propriétés optiques non-linéaires (NLO) et les propriétés thermodynamiques pour le N-(3-methylphenyl)-2-nitrobenzène-sulfonamide de formule brute C13H12N2O4S dans différents solvants. Le niveau de B3LYP donne des résultats similaires pour les paramètres géométriques et les fréquences de vibration en phase gazeuse, eau et éthanol. La structure la plus stable, définie par le plus grand gap énergétique entre HOMO et LUMO, est obtenue en phase gazeuse (ΔE = 3,815888 eV), L’obtention de gaps énergétiques entre HOMO et LUMO démontrent la mobilité à charge élevée dans le composé étudié. L’amplitude du premier paramètre d’hyperpolarisabilité statique (β) augmente avec le décroissement du gap énergétique HOMO–LUMO. Les interactions intensives entre les orbitales liantes et les orbitales antiliantes du composé étudié sont responsables du mouvement du nuage d’électrons π du donneur à l’accepteur, c’est-à-dire le transfert de charge intramoléculaire (TIC), induisant les propriétés optiques non linéaires. Ainsi, le paramètre β pour le composé se trouve dans la gamme de 5,10598–9,03063 × 10−30 esu, indiquant le caractère NLO considérable. Tous les calculs ont été effectués dans la phase gazeuse aussi bien que dans le solvant (l’eau et l’éthanol) afin de démontrer l’effet de solvant sur la structure moléculaire, les fréquences de vibration et les propriétés NLO, etc.
Accurate numerical method for the calculation of doubly excited states in atoms
Authors: Albert M.A. , Laulan S. , Barmaki S.
Published: June 2018

We report in this paper computed values of the energy positions and widths of the lowest 1Po singlet doubly excited states of the helium atom. The results are obtained by a direct numerical solution of the time-independent Schrödinger equation using a discretization technique with B-spline functions combined with complex rotation method. The present approach has the numerical advantage to generate accurate energy positions and widths in a single calculation. The computed data are in very good agreement with results from other theoretical approaches.
Vacuum energy of a nonrelativistic string with nontrivial boundary condition

Published: June 2018

We derive the partition function of a nonrelativistic quantum string whose ends are allowed to freely move along the two-angled straight solid rods. We first derive the classical solution of the model and then use it to derive the partition function utilizing the path integral method. We show that the vacuum energy is the sum of the Lüscher potential plus a term which depends on the relative angle between the rods.
Relative FP-gr-injective and gr-flat modules

Published: June 2018

Let [Formula: see text] be an integer. We introduce the notions of [Formula: see text]-FP-gr-injective and [Formula: see text]-gr-flat modules. Then we investigate the properties of these modules by using the properties of special finitely presented graded modules and obtain some equivalent characterizations of [Formula: see text]-gr-coherent rings in terms of [Formula: see text]-FP-gr-injective and [Formula: see text]-gr-flat modules. Moreover, we prove that the pairs (gr-[Formula: see text], gr-[Formula: see text]) and (gr-[Formula: see text], gr-[Formula: see text]) are duality pairs over left [Formula: see text]-coherent rings, where gr-[Formula: see text] and gr-[Formula: see text] denote the subcategories of [Formula: see text]-FP-gr-injective left [Formula: see text]-modules and [Formula: see text]-gr-flat right [Formula: see text]-modules respectively. As applications, we obtain that any graded left (respectively, right) [Formula: see text]-module admits an [Formula: see text]-FP-gr-injective (respectively, [Formula: see text]-gr-flat) cover and preenvelope.

Moisture Diffusion Characteristics of a Paper Membrane Used for a Cross Flow Enthalpy Exchanger
Authors: Kim Nae-Hyun
Published: June 2018

An enthalpy exchanger is the key component of an enthalpy recovery ventilator, which is installed in apartments or office buildings to maintain proper indoor air quality. In this study, the performance data of the enthalpy exchanger made of paper membrane were obtained for wide range of temperature and humidity conditions. Using the data, diffusion coefficient correlations were developed through modeling of heat and moisture transfer. The heat transfer effectiveness was relatively constant independent of outdoor temperature condition. On the other hand, the moisture transfer effectiveness was highly dependent on outdoor humidity and temperature. In general, moisture transfer effectiveness increased as relative humidity increased. The moisture transfer effectiveness also increased as temperature difference between indoor and outdoor increased. Moisture diffusion coefficient correlations were developed from the data, which predicted the moisture transfer effectiveness was within [Formula: see text]%.
SU(2) Gluon Propagators and the Asymmetry 〈ΔA2〉 in the Postconfinement Domain

We study numerically the chromoelectric-chromomagnetic asymmetry of the [Formula: see text] gluon condensate as well as the transverse and longitudinal gluon propagators at [Formula: see text] in the Landau-gauge [Formula: see text] lattice gauge theory. We show that the previously found point at which asymmetry changes sign is an artifact of the finite volume effects. We find that with increasing temperature the asymmetry decreases approaching zero value from above in agreement with perturbative result. Instead of the asymmetry we suggest the ratio of the transverse to longitudinal propagator taken at zero momentum as an indicator of the boundary of the postconfinement domain and find it at [Formula: see text].
More Guns, Less Butter?: China-U.S. Arms Race Behind Southeast Asia’s Economic Boom
Authors: Pramono Sugiarto
Published: June 2018

Economic growth and arms race are interesting phenomena in Southeast Asia. Contrary to the view of a majority of scholars that arms race has generally negative impact on economic growth, this article argues that the arms race between China and the United States in the South China Sea helps to create a balance of power, which reinforces regional political stability and further drives economic growth. Thus, in an indirect way, the arms race aids economic growth in Southeast Asia. Elaborating on a discourse that arms race is a natural reality in international politics which must be responded to by a positive approach, this study aims to open a new space for debate and further research and offers a new perspective to understand the phenomenon.
Zero energy visible light communication receiver for embedded applications

Published: June 2018

Internet of Things is bringing multiple domains and multiple avenues to connect anything and everything. It mainly uses RF connectivity. However, recently visible light communication (VLC) is also being explored. VLC has the properties that are unique with respect to the privacy and security that it provides. Though the transmission is of broadcast in nature the receiver needs to be in the vicinity of the transmitter, thus providing secure communications. Further, when low power receivers need to be constructed, it is important to harness energy from transmission itself. In this article we propose a novel design for a receiver to be used in VLC for embedded systems. The setup works, using a small solar panel (2mm x 2mm) as a medium to simultaneously harvest incident light energy and receive data bit streams. The LED source was modulated using On-Off Keying. The receiver works for close range communications. The results in this paper show experimental evaluation of the system. We could detect the signals from the source using harvested energy from the same transmission.

Navigation has been an important tool for human civilization for thousands of years, and the latest technologies like online map services and GPS satellites have brought it up to a new level. Now people can easily identify where we are on earth, find any places they want to go, and retrieve best routes to get there. Although there are plenty of tools that are convenient and fast enough for basic uses, it is still far from optimal. For example, most systems only consider various type of distances as the optimization goals, while the traveling time, which needs to consider traffic conditions, is a more appropriate one. However, it is both hard to acquire the traffic condition information and to compute time-dependent fastest paths. Therefore, in this article, we present an introduction to the time-dependent route scheduling, from speed profile generation to route scheduling and query answering.

First Workshop on Developmental Neural Networks
Authors: Miller Julian F , Cussat-Blanc Sylvain , Wilson Dennis G
Published: June 2018

In nature, brains are built through a process of biological development in which many aspects of the network of neurons and connections change are shaped by external information received through sensory organs. Biological development mechanisms such as axon guidance and dendrite pruning have been shown to rely on neural activity. Despite this, most artificial neural network (ANN) models do not include developmental mechanisms and regard learning as the adjustment of connection weights, while some that do use development restrain it to a period before the ANN is used. It is worthwhile to understand the cognitive functions offered by development and to investigate the fundamental questions raised by artificial neural development. In this workshop, we will explore existing and future approaches that aim to incorporate development into ANNs. Invited speakers will present their work with neural networks, both artificial and biological, in the context of development. Accepted submissions on contemporary work in this field will be presented and we will hold an open discussion on the topic.

Attendees of Artificial Evolution (EA 2017), held in Paris, France, were treated to a cocktail reception and vernissage, or private viewing, of the "Art&Science in Evolutionary Computation" art exhibition at Galerie Louchard in Paris. The exhibition ran from 24 October to 12 November 2017. The selected artworks were created through a number of evolutionary methods: ant-based clustering, predator-prey model, evolutionary algorithms and fly algorithm. The corresponding papers are published in volume 1 of the newly-launched Art and Science journal (ISTE OpenScience). EA 2017 attendees had the opportunity to engage with the artists and mingle over a wide array of delightful hors-d'oeuvres.

We conducted an analysis of the GECCO 2017 submission data. We also considered historical submission data since 2005 when the proceedings started to be handled by the ACM and thus accessible via the ACM digital library. Considering the full papers appearing in the proceedings since 2005, we extracted and visualised the co-authorship network.
Exertional dyspnea and operating lung volumes in asthma

Published: June 2018

Dyspnea has been reported to be a main contributor to exercise avoidance in asthma. While traditional markers of ventilation do not explain the heightened dyspnea during exercise in patients with asthma, this study proposed that exertional dyspnea in asthma was due to high-operating lung volumes, which may be improved with a short-acting β2-agonist. On two separate days, 16 patients with asthma and 16 controls completed a lung function test and incremental exercise tests to exhaustion. On one of the days (order randomized), 400 µg salbutamol was administered before exercise. Inspiratory capacity (IC), inspiratory reserve volume (IRV), and dyspnea (modified Borg scale) were evaluated throughout exercise. Compared with controls, patients with asthma reported greater dyspnea at the same absolute submaximal workloads. Furthermore, patients with asthma demonstrated altered breathing responses to exercise, characterized by reduced IC and IRV throughout exercise compared with controls. The reduced IRV was associated with increased dyspnea in patients with asthma. Salbutamol did not affect dyspnea or operating lung volumes in either group. The increased perception of dyspnea during incremental exercise in patients with asthma appears to be secondary to a reduction in IRV, which is unaffected by an inhaled β2-agonist.

NEW & NOTEWORTHY Increased exertional dyspnea in asthma appears to be due to high operating lung volumes and is not affected by salbutamol.
Regular walking breaks prevent the decline in cerebral blood flow associated with prolonged sitting

Decreased cerebrovascular blood flow and function are associated with lower cognitive functioning and increased risk of neurodegenerative diseases. Prolonged sitting impairs peripheral blood flow and function, but its effects on the cerebrovasculature are unknown. This study explored the effect of uninterrupted sitting and breaking up sitting time on cerebrovascular blood flow and function of healthy desk workers. Fifteen participants (10 male, 35.8 ± 10.2 yr, body mass index: 25.5 ± 3.2 kg/m2) completed, on separate days, three 4-h conditions in a randomized order: 1) uninterrupted sitting (SIT), 2) sitting with 2-min light-intensity walking breaks every 30 min (2WALK), or 3) sitting with 8-min light-intensity walking breaks every 2 h (8WALK). At baseline and 4 h, middle cerebral artery blood flow velocity (MCAv) and CO2 reactivity (CVR) of the MCA and carotid artery were measured using transcranial Doppler (TCD) and duplex ultrasound, respectively. Cerebral autoregulation (CA) was assessed with TCD using a squat-stand protocol and analyzed to generate values of gain and phase in the very low, low, and high frequencies. There was a significant decline in SIT MCAv (−3.2 ± 1.2 cm/s) compared with 2WALK (0.6 ± 1.5 cm/s, P = 0.02) but not between SIT and 8WALK (−1.2 ± 1.0 cm/s, P = 0.14). For CA, the change in 2WALK very low frequency phase (4.47 ± 4.07 degrees) was significantly greater than SIT (−3.38 ± 2.82 degrees, P = 0.02). There was no significant change in MCA or carotid artery CVR ( P > 0.05). Results indicate that prolonged uninterrupted sitting in healthy desk workers reduces cerebral blood flow; however, this is offset when frequent short-duration walking breaks are incorporated.

NEW & NOTEWORTHY Prolonged uninterrupted sitting in healthy desk workers reduces cerebral blood flow. However, this reduction in cerebral blood flow is offset when frequent short-duration walking breaks are incorporated into this sitting period. For those who engage in long periods of sedentary behavior, chronically breaking up these sitting periods with frequent active break strategies may have important implications for cerebrovascular health; however, further research should explore this hypothesis.

This study presents harmonic analysis of precipitation observations within the Lake Tana Basin for the periods of 1985–2015. The livelihood of several millions of people within the basin and outside the basin is governed by the precipitation conditions within this basin. Large spatial and temporal variabilities of precipitation can increase the incidence of extreme events such as floods and droughts. It is important to identify the characteristics of these variations, and this study aims at investigating the characteristics of the seasonal and annual cycles of precipitation within the Lake Tana Basin using harmonic analysis. Precipitation data of 31 years from four weather stations were used in the analysis. We then applied harmonic analysis to calculate the amplitude, phase shift, and variance of observation. Detailed characteristics of the first five harmonics are presented and discussed. We found the amplitude of the first harmonic to be 173.42, 177.93, 127.77, and 188.78  mm for Debre Tabor, Bahir Dar, Gondar, and Dangila, respectively. This shows that Dangila areas got more rainfall during this fundamental period than others increasing from Gondar to Dangila direction. Also, the variance in the first harmonic is smaller than the variances of other harmonics, and this means that the large variations of the precipitation originate from higher harmonics (short time periods). This shows that precipitation variations are governed mainly by monthly, seasonal, and semiannual variations. The analysis has shown that maximum precipitation for all stations occurred in July and August.
