Increased virulence of rabbit haemorrhagic disease virus associated with genetic resistance in wild Australian rabbits (Oryctolagus cuniculus)

The release of myxoma virus (MYXV) and Rabbit Haemorrhagic Disease Virus (RHDV) in Australia with the aim of controlling overabundant rabbits has provided a unique opportunity to study the initial spread and establishment of emerging pathogens, as well as their co-evolution with their mammalian hosts. In contrast to MYXV, which attenuated shortly after its introduction, rapid attenuation of RHDV has not been observed. By studying the change in virulence of recent field isolates at a single field site we show, for the first time, that RHDV virulence has increased through time, likely because of selection to overcome developing genetic resistance in Australian wild rabbits. High virulence also appears to be favoured as rabbit carcasses, rather than diseased animals, are the likely source of mechanical insect transmission. These findings not only help elucidate the co-evolutionary interaction between rabbits and RHDV, but reveal some of the key factors shaping virulence evolution.

Developmental biology and prey preference of Diomus notescens Blackburn (Coleoptera: Coccinellidae): A predator of Aphis gossypii Glover (Hemiptera: Aphididae)

The minute two-spotted ladybeetle, Diomus notescens Blackburn is a common predator of aphids and other pests in Australian agricultural crops, however little is known about the biology of D. notescens. The aim of this study was to provide information on the life cycle of this predator and improve our understanding of its biological control potential, particularly against one of the major pests of cotton, Aphis gossypii Glover. In laboratory experiments, juvenile development, prey consumption, as well as adult lifespan and fecundity were studied. Results from this study revealed that D. notescens could successfully complete development on A. gossypii, which at 25 °C required 21 days and during this period they each consume 129 ± 5.2 aphids. At 25 °C adult lifespan was 77 ± 9.6 days, with a mean daily prey consumption of 28 ± 1.8 aphids and a mean daily fecundity of 8 ± 0.5 eggs. Net reproductive rate was estimated as 187 ± 25.1 females and the intrinsic rate of increase was estimated as 0.14. Juvenile development was recorded at four constant temperatures (15, 21, 26 and 27 °C) and using a linear model, the lower threshold for D. notescens development was estimated to be 10 ± 0.6 °C with 285 ± 4.7 degree days required to complete development. A prey choice experiment studying predation rates revealed a strong preference for A. gossypii nymphs compared to Bemisia tabaci Gennadius eggs.

Can technology provide a glimmer of hope for economic growth in the midst of chaos? A case of Zimbabwe

In this paper we examine the effect of technology on economic growth in Zimbabwe over the period 1975–2014 whilst accounting for structural breaks. We use the extended Cobb–Douglas type Solow (Q J Econ 70(1):65–94, 1956) framework and the ARDL bounds procedure to examine cointegration and short run and long run effects. Using unit root tests, we note that structural changes in Zimbabwe are generally marked by the period 1982 onwards. We find that mobile technology has a positive short-run (0.09 %) and long-run (0.08 %) impact on the output per capita. The structural changes post-1982 periods show positive impact in the short-run (0.06) and the long-run (0.09), whereas the coefficient of trend in the short-run (−0.03) and the long-run (−0.04) is negative. The Granger non-causality test shows a unidirectional causality from capital stock (investment) per capita to output per capita and a bi-directional causality between mobile cellular technology and output per capita. The plausible reasons for estimated magnitude effects and the direction of causality are explained for policy deliberation.

Eläinsuojelu elämänpolitiikkana : Tutkimus eläinasialiikkeestä ja Eläinsuojeluliitto Animalian jäsenistä

Tutkielmassa tarkastellaan perinteiseen, maltilliseen eläinsuojelujärjestöön kuuluvien eläinsuojelijoiden elämänpolitiikkaa ja suomalaista eläinasialiikettä, joka aikaisemmin on hahmotettu lähinnä uuden, radikaalin eläinoikeusaktivismin kautta. Uskontososiologian ja -antropologian alaan sijoittuva tutkimus ottaa osaa sosiologi Anthony Giddensin elämänpolitiikan käsitteestä käytyyn keskusteluun empiirisestä näkökulmasta. Tutkimusongelma on kaksitasoinen.Yksilön tasolla tarkastelu kohdistuu Eläinsuojeluliitto Animaliassa aktiivisesti toimivien eläinsuojelijoiden elämäntapoihin, mielipiteisiin, arvoihin ja ihanteisiin. Liikkeen tasolla tarkastellaan eläinasialiikettä ja sen oletettua jakautumista eläinsuojelu- ja eläinoikeusliikkeisiin. Tutkimuksen taustateorioina ovat Giddensin teoria elämänpolitiikasta sekä filosofi Peter Singerin ja filosofi Tom Reganin teoriat eläinten hyvinvoinnista ja oikeuksista. Suomalaista näkökulmaa eläinasian teoriaan edustavat filosofi Leena Vilkan pohdinnat. Tutkimuksen primääriaineiston muodostavat 12 eläinsuojelijan yksilö- ja ryhmähaastatteluina toteutetut teemahaastattelut sekä 22 eläinsuojelijan lomakekyselynä kerätyt taustatiedot. Sekundääriaineisto koostuu eläinsuojelijoille tehdyistä taustatieto- ja sähköpostihaastatteluista, havainnointiin perustuvasta kenttäpäiväkirjasta, eläinasialiikkeen kirjallisesta materiaalista sekä tutkimusaiheeseen liittyvästä aikaisemmasta tutkimuksesta ja kirjallisuudesta. Tutkimuksen perusteella elämänpolitiikan teoria on käyttökelpoinen arvotutkimuksessa. Eläinsuojelijoiden elämänpolitiikkaa luonnehtivat reflektiivisyys; elämäntavan käyttäminen vaikutuskeinona puoluepolitiikan ohella; yhteiskuntatieteilijä Ronald Inglehartin määrittelyn mukaiset post-materialistiset arvot; tilanne- ja tuotekohtaisesti kontrolloitu tapa kuluttaa; argumentoiva ja vaativa suhtautuminen traditioihin; pyrkimys eroon hierarkioista; paikallisuus toiminnassa ja tavoitteissa; pyrkimys vaikuttaa ihmisten, eläinten ja ympäristön tulevaisuuteen ja kaksijakoinen suhtautuminen asiantuntijoihin. Tutkimuksessa asetetaan kyseenalaiseksi kahden erillisen, suomalaisen eläinasialiikkeen olemassaolo ja osoitetaan, että Suomessa voidaan puhua eläinasialiikkeestä, jossa eri aikakausina, yksilö- ja järjestökohtaisesti, painotetaan aiheittain joko maltillisia tai radikaaleja näkökulmia. Avainsanat: elämänpolitiikka, eläinsuojelu, eläinasialiike, elämäntapa, mielipiteet, arvot, ihanteet

Economics of tourism & growth for small island countries

We theoretically analyze the impact of changes in foreign income from tourism source countries on the growth of tourism dependent small island economies. Using a general theoretical construct, we attempt to answer the question of how price elasticity of demand, income elasticity of tourist and the degree of competition in the service sector influence the economic development of small economies. One of the main results is that politicians may consider applying policies which lead to a competitive environment in the service sector to maximize growth and the consequent labor income share.

Interdependence between Greece and other European stock markets: A comparison of wavelet and VMD copula, and the portfolio implications

The interdependence of Greece and other European stock markets and the subsequent portfolio implications are examined in wavelet and variational mode decomposition domain. In applying the decomposition techniques, we analyze the structural properties of data and distinguish between short and long term dynamics of stock market returns. First, the GARCH-type models are fitted to obtain the standardized residuals. Next, different copula functions are evaluated, and based on the conventional information criteria and time varying parameter, Joe-Clayton copula is chosen to model the tail dependence between the stock markets. The short-run lower tail dependence time paths show a sudden increase in comovement during the global financial crises. The results of the long-run dependence suggest that European stock markets have higher interdependence with Greece stock market. Individual country’s Value at Risk (VaR) separates the countries into two distinct groups. Finally, the two-asset portfolio VaR measures provide potential markets for Greece stock market investment diversification.

The psychometric properties of the Kessler Psychological Distress Scale (K6) in a general population sample of adolescents

The 6-item Kessler Psychological Distress Scale (K6; Kessler et al., 2002) is a screener for psychological distress that has robust psychometric properties among adults. Given that a significant proportion of adolescents experience mental illness, there is a need for measures that accurately and reliably screen for mental disorders in this age group. This study examined the psychometric properties of the K6 in a large general population sample of adolescents (N = 4,434; mean age = 13.5 years; 44.6% male). Factor analyses were conducted to examine the dimensionality of the K6 in adolescents and to investigate sex-based measurement invariance. This study also evaluated the K6 as a predictor of scores on the Strengths and Difficulties Questionnaire (SDQ; Goodman, 1997). The K6 demonstrated high levels of internal consistency, with the 6 items loading primarily on 1 factor. Consistent with previous research, females reported higher mean levels of psychological distress when compared with males. The identification of sex-based measurement noninvariance in the item thresholds indicated that these mean differences most likely represented reporting bias in the K6 items rather than true differences in the underlying psychological distress construct. The K6 was a fair to good predictor of abnormal scores on the SDQ, but predictive utility was relatively low among males. Future research needs to focus on refining and augmenting the K6 scale to maximize its utility in adolescents. (PsycINFO Database Record (c) 2015 APA, all rights reserved)

Variation i kvinnors namnfraser i officiella dokument i Helsingfors 1780-1930 : Socioonomastiska synvinklar på makt och identitet

This dissertation is an onomastic study of variation in women s name phrases in official documents in Finland during the period 1780−1930. The aim is to discuss from a socio-onomastic perspective both the changeover from patronymics to inherited family names and the use of surnames after marriage (i.e. whether women adopted their husbands family names or retained their maiden names), before new laws in this area entered into force in Finland in the early 20th century. In 1920, a law on family names that required fixed names put an end to the use of the patronymic as a person s only surname. After 1929, it was no longer possible for a married woman to retain her maiden name. Methodologically, to explain this development from a socio-onomastic perspective, I have based my study on a syntactic-semantic analysis of the actual name phrases. To be able to demonstrate the extensive material, I have elaborated a scheme to divide the 115 different types of name phrases into 13 main categories. The analysis of the material for Helsinki is based on frequency calculations of the different types of name phrases every thirtieth year, as well as on describing variation in the structure and semantic content of the name phrases, e.g. social variation in the use of titles and epithets. In addition to this, by applying a biographic-genealogical method, I have conducted two case studies of the usage of women s name phrases in the two chosen families. The study is based on parish registers from the period 1780−1929, estate inventory documents from the period 1780−1928, registration forms for liberty of trade from the period 1880−1908, family announcements on newspapers from the period 1829−1888, gravestones from the period 1796−1929 and diaries from the periods 1799−1801 and 1818−1820 providing a corpus of 5 950 name phrases. The syntactic-semantic analysis has revealed the overall picture of various ways of denoting women in official documents. In Helsinki, towards the end of the 19th century, the use of inherited family names seems to be almost fully developed in official contexts. At the late 19th century, a patronymic still appears as the only surname of some working-class women whereas in the early 20th century patronymics were only entered in the parish register as a kind of middle name. In the beginning of the 19th century, most married women were still registered under their maiden names, with a few exceptions among the bourgeoisie and upper class. The comparative analysis of name phrases in diaries, however, indicates that the use of the husband s family name by married women was a much earlier phenomenon in private contexts than in official documents. Keywords: socio-onomastics, syntactic-semantic analysis, name phrase, patronymic, maiden name, husband s family name

An Analysis of the Concept of Citizenship: Legal, Political and Social Dimensions

The thesis aims at analyzing concept of citizenship in political philosophy. The concept of citizenship is a complex one: it does not have a definitive explication, but it nevertheless is a very important category in contemporary world. Citizenship is a powerful ideal, and often the way a person is treated depends on whether he or she has the status of a citizen. Citizenship includes protection of a person’s rights both at home and abroad. It entails legal, political and social dimension: the legal status as a full member of society, the recognition of that status by fellow citizens and acting as a member of society. The thesis discusses these three dimensions. Its objective is to show how all of them, despite being insufficient in some aspects, reach something important about the concept. The main sources of the thesis are Civic Republicanism by Iseult Honohan (Routledge 2002), Republicanism by Philip Pettit (Clarendon Press 1997), and Taking Rights Seriously by Ronald Dworkin (1997). In addition, the historical part of the thesis relies mainly on the works of Aristotle, Immanuel Kant, Adam Smith, Quentin Skinner, James Pocock and James Tully. The writings of Will Kymlicka, John Rawls, Chantal Mouffe, and Shane Phelan are referred to in the presentation and critique of the liberal tradition of thought. Hannah Arendt and Seyla Benhabib’s analysis of Arendt’s philosophy both address the problematic relations between human rights and nation-states as the main guarantors of rights. The chapter on group rights relies on Peter Jones’ account of corporate and collective rights, after which I continue to Seumas Miller’s essay on the (liberal) account of group rights and their relation to the concept of citizenship. Republicanism and Political Theory (2002) edited by Cécile Laborde and John Maynor is also references. David Miller and Maurizio Viroli represent the more “rooted” version of republicanism. The thesis argues that the full concept of citizenship should be seen as containing legal, political and social dimensions. The concept can be viewed from all of these three angles. The first means that citizenship is connected with certain rights, like the right to vote or stand for election, the right to property and so on. In most societies, the law guarantees these rights to every citizen. Then there is also the social dimension, which can be said to be as important as the legal one: the recognition of equality and identities of others. Finally, there is the political dimension, meaning the importance of citizens’ participation in the society, which is discussed in connection with the contemporary account of republicanism. All these issues are discussed from the point of view of groups demanding for group-specific rights and equal recognition. The challenge with these three aspects of citizenship is, however, that they are difficult to discuss under one heading. Different theories or discourses of citizenship each approach the subject from different starting points, which make reconciling them sometimes hard. The fundamental questions theories try to answer may differ radically depending on the theory. Nevertheless, in order to get the whole image of what the citizenship discourses are about all the aspects deserve to be taken into account.

Photochemical intramolecular gamma-hydrogen abstraction in a ketone and an alkene and the role of tunneling of hydrogen

Intramolecular gamma-hydrogen abstraction reactions were examined in pentane-2-one and 2-methyl-1-pentene in their lowest triplet states using the AM1 semi-empirical molecular orbital method with the complete geometry optimization in the unrestricted Hartree-Fock frame. The results reveal that the oxygen atom of the carbonyl group and the end carbon atom of the olefinic bond acquire high free valence and spin density indices in their respective lowest triplet states, leading to abstraction of hydrogen from the gamma-position relative to the carbonyl and olefinic bonds. The theoretical energy profiles fit with a polynomial and the probability of tunneling of hydrogen was estimated by the WKB (Wentzel, Kramer and Brillouin) method. The results, after thermal averaging of the rate constants, reveal that tunneling of hydrogen is significant at room temperature.

Time-resolved resonance Raman spectroscopic investigations of the photochemistry of ubiquinone

Time-resolved resonance Raman spectroscopy has been used to investigate the photochemistry of ubiquinone in cyclohexane, water and ethanol. In water the absorption of a single 248 nm photon produces triplet ubiquinone which then oxidises water, via electron transfer, to form the ubiquinone radical anion. In ethanol, however, the triplet state reacts with the solvent via both electron and hydrogen-atom transfer, the latter process forming the semihydroquinone. Only in the less reactive solvent, cyclohexane, is triplet quinone observed. The Raman bands observed for each of the species are assigned on the basis of similarities of their spectra to other quinones.

Contractive Hilbert modules and their dilations

In this note, we show that a quasi-free Hilbert module R defined over the polydisk algebra with kernel function k(z,w) admits a unique minimal dilation (actually an isometric co-extension) to the Hardy module over the polydisk if and only if S (-1)(z, w)k(z, w) is a positive kernel function, where S(z,w) is the Szego kernel for the polydisk. Moreover, we establish the equivalence of such a factorization of the kernel function and a positivity condition, defined using the hereditary functional calculus, which was introduced earlier by Athavale [8] and Ambrozie, Englis and Muller [2]. An explicit realization of the dilation space is given along with the isometric embedding of the module R in it. The proof works for a wider class of Hilbert modules in which the Hardy module is replaced by more general quasi-free Hilbert modules such as the classical spaces on the polydisk or the unit ball in a'', (m) . Some consequences of this more general result are then explored in the case of several natural function algebras.

Lizard Wears Shades. A Spectacled Sphenomorphus (Squamata: Scincidae), from the Sacred Forests of Mawphlang, Meghalaya, North-east India

A new species of lygosomatine scincid lizard is described from the sacred forests of Mawphlang, in Meghalaya, northeastern India. Sphenomorphus apalpebratus sp. nov. possesses a spectacle or brille, an unusual feature within the Scincidae, and a first for the paraphyletic genus Sphenomorphus. The new species is compared with other members of the genus to which it is here assigned, as well as to members of the lygosomatine genera Lipinia and Scincella from mainland India, the Andaman and Nicobar Islands, and south-east Asia, to which it also bears resemblance. The new taxon is diagnosable in exhibiting the following combination of characters: small body size (SVL to 42.0 mm); moveable eyelids absent; auricular opening scaleless, situated in a shallow depression; dorsal scales show a line of demarcation along posterior edge of ventral pes; midbody scale rows 27-28; longitudinal scale rows between parietals and base of tail 62-64; lamellae under toe IV 8-9; supraoculars five; supralabials 5-6; infralabials 4-5; subcaudals 92; and dorsum golden brown, except at dorsal margin of lateral line, which is lighter, with four faintly spotted lines, two along each side of vertebral row of scales, that extend to tail base. The new species differs from its congeners in the lack of moveable eyelids, a character shared with several distantly related scincid genera.
