On the evolution of the radio pulsar PSR J1734−3333
No full textRecent measurements showed that the period derivative of the ‘hig
h-B’ radio pulsar PSR J1734−3333 is increasing with time. For neutron stars evolving with fallback disks, this rotational behavior is expected in certain phases of the long-term evolution. Using the same model as employed earlier to explain the evolution of anomalous X-ray pulsars and soft gamma-ray repeaters, we show that the period,the first and second period derivatives and the X-ray luminosity of this source can simultaneously acquire the observed values for a neutron star evolving with a fallback disk. We find that the required strength of the dipole field that can produce the source properties is in the range of 10^12 − 10^13 G on the pole of the neutron star. When the model source
reaches the current state properties of PSR J1734−3333, accretion onto the star has not started yet, allowing the source to operate as a regular radio pulsar. Our results imply that PSR J1734−3333 is at an age of ∼3×10^4 −2×10^5years. Such sources will have properties like the X-ray dim isolated neutron stars or transient AXPs at a later epoch of weak accretion from the diminished fallback disk

Abstract
The COVID-19 pandemic outbreak has dramatically worsened people’s psychological well-being. Our aim was to examine for the first time the concurrent and longitudinal relations of family resilience with hedonic and eudaimonic well-being, and the moderating role of socio-demographics. For people having a romantic partner, we also explored whether family resilience and dyadic coping were uniquely related to well-being. One cross-sectional study (N = 325) and one 10-week follow-up study (N = 112) were carried out during the outbreak of the COVID-19 pandemic (April–May 2020) in Northern Italy. Adult participants completed an online questionnaire in both studies. Correlation, multivariate regression, and moderation analyses were carried out with IBM SPSS version 28 and its PROCESS macro. Significance of differences in correlation and regression coefficients was tested through Steiger’s procedure, Wald test, and SUEST method. Family resilience was found to relate more strongly to eudaimonic (versus hedonic) well-being concurrently and to hedonic (versus eudaimonic) well-being longitudinally. The concurrent or longitudinal relations with hedonic well-being were generally stronger for females, part-time workers, and people undergoing multiple stressors. For people having a romantic partner, family resilience was concurrently associated with well-being independently of dyadic coping, whereas dyadic coping was longitudinally related to well-being independently of family resilience. Family resilience was found to protect, in the short term, the psychological well-being of people facing the pandemic outbreak. Its protective role mainly concerned hedonic well-being and was more pronounced for more vulnerable people. For persons having a romantic partner, however, dyadic coping seemed to have equal, if not greater, positive short-term effects

A Multi-Language Comparison of Influences on Author Verification using Character N-Grams
No full textWe create a new multi-language corpus for author verification based on Wikipedia talkpages, and evaluate the influence that differences in topic and time have on character n-gram author profiles. Topic alignment between two texts is found to increase author verification precision, and an authors writing style is found to change over time, but not more significantly after 3 years than after 1 year.Information ArchitectureWISElectrical Engineering, Mathematics and Computer Scienc
Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis

Description. All specimens incomplete, holotype 6.6 mm long, 0.24 mm wide, with 38 chaetigers. Body slender, enlarged anteriorly, gradually tapering to posterior end. Color in alcohol opaque white. Prostomium truncate on anterior margin, slightly inflated at level of eyes, tapering posteriorly to form narrow caruncle extending to chaetiger 2; without anterior or lateral marginal peaks. Four eyes present, anterior pair small and rounded; posterior pair large and crescent-shaped (Fig. 3 A–B). Peristomium fused to chaetiger 1, not forming lateral wings; palps thickened, extending posteriorly for 7–8 chaetigers, with small ripples on the edge of the palps (Fig. 3 B). Branchiae present from chaetiger 2 to 5; 4 pairs; first 3 pairs pinnate, last pair apinnate; each pinnate branchia with digitiform pinnules (Figs. 3; 4 A, C; 5 A–C). First pair largest, extending to chaetiger 5, with dense digitiform pinnules except on distal and subdistal parts (Fig. 5 A); second and third pairs equal in length with few pinnules not extending to tip; shorter than first pair (Fig. 5 B); last pair of branchiae apinnate narrow, shorter than others, heavily ciliated (Fig. 5 C). Parapodia of chaetiger 1 reduced; notopodial and neuropodial postsetal lamellae smaller than those of succeeding chaetigers, with capillary chaetae only (Fig. 3 A). Notopodial lamella foliaceous, largest in branchial region; subsequent parapodia with heart-shaped lamellae, posterior parapodia with rounded lamellae (Figs. 3 A, 5 A–C). Dorsal crests first present on chaetiger 7, continuing through chaetiger 19 (chaetigers 24–25 in paratypes) (Fig. 5 D–F). Neuropodial postchaetal lamellae small, somewhat leaf-shaped on chaetiger 2; largest, subrectagular on chaetiger 3 (Fig. 3 A); gradually becoming rounded, smallest in last posterior chaetigers (Fig. 5 G–H). Interparapodial pouches absent. Anterior noto- and neuropodial capillaries moderately granulated, with thin sheath (Fig. 5 I); chaetae arranged in two rows; chaetae of anterior row shorter than those of posterior row. Neuropodial hooded hooks present from chaetiger 16 (18 in paratypes), numbering up to 7 per fascicle; notopodial hooded hooks from chaetiger 30, numbering up to 4–5 per fascicle; hooks with 4–5 pairs of small teeth above main fang (Figs. 4 B, 5 J), secondary hood conspicuous; hooks accompanied by capillaries throughout. Ventral sabre chaeta first present on neuropodia of chaetiger 10; lightly granulated; numbering one or two per fascicle (Fig. 5 K). Pygidium missing on all specimens. Remarks. Prionospio (Prionospio) ergeni n. sp. is easily distinguished from other species of the genus in having three pairs of pinnate branchia on chaetigers 2–4 and one pair of apinnate branchiae on chaetiger 5, and a weakly developed dorsal crest on chaetiger 6. Other species of Prionospio have other combinations of pinnate and apinnate branchiae, but none have digitiform pinnules on the first three pairs of branchiae. Prionospio (P.) plumosa Sars, 1872 and P. (P.) tripinnata Maciolek, 1985 also have three pairs of pinnate branchiae and one pair of apinnate branchiae, but these two species can be easily distinguished from P. (P.) ergeni n. sp. by the arrangement and morphological features of the branchiae. Prionospio (P.) tripinnata, which was originally described from the Mediterranean Sea at 500 and 509 m by Maciolek (1985), has pinnate branchiae on chaetigers 2, 3, and 5, and apinnate branchiae on chaetiger 4. Other differences between P. (P.) ergeni n. sp. and P. (P.) tripinnata are: (1) eyes are absent in P. (P.) tripinnata vs. present in P. (P.) ergeni n. sp., (2) the pinnate branchiae on chaetiger 3 of P. (P.) tripinnata, which has sparse pinnules, are shorter than those on chaetigers 2 and 4 vs. equal in length in P. (P.) ergeni n. sp., and (3) neuropodial hooded hooks are present from chaetiger 12 in P. (P.) tripinnata vs. chaetiger 16 in P. (P.) ergeni n. sp. Prionospio (P.) plumosa, which was originally described from Norway by Sars (1872), has a branchial arrangement similar to that of P. (P.) tripinnata but differs from it mainly in having long pinnate branchiae on chaetiger 3 (vs. short branchiae in P. (P.) tripinnata). Ecology. The highest population density (525 individuals.m - 2) of this species was found on sandy substratum at 5 m depth at station K 10 (near Yumurtalik Harbour). Distribution. Eastern Mediterranean Sea. Etymology. This species is named for Prof. Dr. Zeki Ergen, emeritus scientist from Ege University, who made excellent contributions to the understanding of polychaete diversity inhabiting the Turkish as well as eastern Mediterranean coasts.Published as part of Dagli, Ertan & Çinar, Melih Ertan, 2009, Species of the subgenera Aquilaspio and Prionospio (Polychaeta: Spionidae: Prionospio) from the southern coast of Turkey (Levantine Sea, eastern Mediterranean), with description of a new species and two new reports for the Mediterranean fauna, pp. 1-20 in Zootaxa 2275 on pages 7-11, DOI: 10.5281/zenodo.19105
The vanishing author in computer-generated works: a critical analysis of recent Australian case law
No full textAbstract
The use of software is ubiquitous in the creation of many copyright works, yet the requirement in copyright law that every work have a human author who engages in independent intellectual effort means that its use may prevent copyright subsistence. Several recent Australian cases have refocused attention on authorship as an essential criterion of copyright subsistence, and these cases suggest that much computer-produced output may be authorless and thus lack copyright protection. This article, the first in a two-part series, analyses how each case deals with the question of authorship of computer-produced works and why the use of software diminishes copyright protection for a significant number of computer-generated works. The article critiques the application of conventional notions of human authorship developed in the pre-computer age to modern productions and suggests alternative approaches to authorship that satisfy both the major objectives of copyright policy and the need to adapt to the computer age. The article argues that, without a broader judicial approach to authorship of computer-generated works, Parliament must remedy the lacuna in protection for these ‘authorless’ works. Possible solutions for reform are suggested. In a forthcoming article, the author comprehensively examines those reform proposals

Diffusive author(s), cohesive author: Analysis of S/N (1994)
No full textThis study indicates the ways in which various aspects of the author(s) are brought forth in Dumb type’s performance art, the S/N production. Previous research has suggested a non-hierarchical organization of Dumb type and the absence of a “privileged author” in Dumb type’s collaborative work, S/N. However, the results that I have investigated from member’s interviews on the creative process of S/N along with my analysis of the recorded images of S/N, indicate a different aspect of the author(s). First, S/N was created through, so to speak, the collective ideas of the members of Dumb type. Further, S/N has at least nine quotations from previous performances, installations, and printed writings, besides the work-in-progress technique. Explicating one of the “author functions” as given by Michel Foucault, each text has plural subjects of the author. However, it has been revealed from members’ interviews that Teiji Furuhashi had a decision-making role in selecting the members’ ideas within the performance. Since then, S/N has had plural subjects of creation; however, Furuhashi is one of the subjects of creation along with the “privileged author.” S/N has plural authors (diffusive authors) yet at the same time, it has a “privileged author,” Teiji Furuhashi (cohesive author)
