Arlis/ANZ 2.0
We've all been hearing about Web 2.0 and Library 2.0 lately. But just what are they all about, and is there anything there that Arlis/ANZ can take advantage of in order to better go about its business? Can there, should there, be an Arlis/ANZ 2.0? Arlis/ANZ, the Arts Libraries Society of Australia and New Zealand, is preparing to review it's online prescence. The Arlis/ANZ website is now three years old, and has been well maintained during that time. However it has not yet been systematically reviewed in terms of content, functionality, and strategic direction. The Arlis/ANZ Website version 'One' will be redeveloped into Arlis/ANZ Website version 'Two'. Although much of that review will concentrate on the structure, look and feel of the site, the review process offers an opportunity to incorporate Web 2.0 developments. By incorporating that 'best' of Web 2.0 in a strategic manner, Arlis/ANZ 2.0 - the website - has powerful potential to contribute toward the strength, cohesion and ongoing development of Arlis/ANZ 2.0 - the Society
Smile detection in the wild based on transfer learning
Smile detection from unconstrained facial images is a specialized and
challenging problem. As one of the most informative expressions, smiles convey
basic underlying emotions, such as happiness and satisfaction, which lead to
multiple applications, e.g., human behavior analysis and interactive
controlling. Compared to the size of databases for face recognition, far less
labeled data is available for training smile detection systems. To leverage the
large amount of labeled data from face recognition datasets and to alleviate
overfitting on smile detection, an efficient transfer learning-based smile
detection approach is proposed in this paper. Unlike previous works which use
either hand-engineered features or train deep convolutional networks from
scratch, a well-trained deep face recognition model is explored and fine-tuned
for smile detection in the wild. Three different models are built as a result
of fine-tuning the face recognition model with different inputs, including
aligned, unaligned and grayscale images generated from the GENKI-4K dataset.
Experiments show that the proposed approach achieves improved state-of-the-art
performance. Robustness of the model to noise and blur artifacts is also
evaluated in this paper
Exploiting Prior Knowledge in Compressed Sensing Wireless ECG Systems
Recent results in telecardiology show that compressed sensing (CS) is a
promising tool to lower energy consumption in wireless body area networks for
electrocardiogram (ECG) monitoring. However, the performance of current
CS-based algorithms, in terms of compression rate and reconstruction quality of
the ECG, still falls short of the performance attained by state-of-the-art
wavelet based algorithms. In this paper, we propose to exploit the structure of
the wavelet representation of the ECG signal to boost the performance of
CS-based methods for compression and reconstruction of ECG signals. More
precisely, we incorporate prior information about the wavelet dependencies
across scales into the reconstruction algorithms and exploit the high fraction
of common support of the wavelet coefficients of consecutive ECG segments.
Experimental results utilizing the MIT-BIH Arrhythmia Database show that
significant performance gains, in terms of compression rate and reconstruction
quality, can be obtained by the proposed algorithms compared to current
CS-based methods.Comment: Accepted for publication at IEEE Journal of Biomedical and Health

Deployment Stress and Parenting Self-Efficacy Among Spouses of Members of the Armed Forces
Deployment in the Armed Forces has a ripple effect on the family unit. Research suggests deployment impacts the psychological well-being of military spouses and children. The spouse who stays behind plays an important role in maintaining homeostasis while adapting to the absence of the deployed servicemember. The present study aimed to understand whether there is an association between deployment stress and parental self-efficacy. The study examined these variables in 115 military spouses of active and reserve units whose servicemembers are currently on deployment or deployed within the last two years and who are parents to children between the ages of 5 and 18. Overall, data did not support a relationship between deployment stress and parental self-efficacy. However, number of deployments showed a significant relationship on parental self-efficacy in relationship to providing nurturance and empathic responses to children. Number of deployments also yielded a significant relationship in how military spouses reported feeling competent, restricted, conflicted, supported, and/or depressed in their role as a parent. Supporting or engaging in recreational activities with children had a significant adverse effect on relationship satisfaction. Conversely, military spouseâs interpersonal relationships and social support positively affected the relationship between military spouses and servicemembers. Self-esteem, self-reliance, seeking social support and psychological acceptance of deployment helped in reduction of stress which affected parental self-efficacy and lowered levels of parental stress. Developing supportive relationships and engaging in behaviors of self-development was associated with lower levels of stress and tension from deployment and stronger parental belief in ability to support cognitive and socio-emotional adjustment of child/children. Among covariates, family income was a significant predictor of military spousesâ family integrity, self-reliance and self-esteem, interpersonal relationships and social support, belief in the value of the militaryâs mission, and lower psychological tension and strain during servicememberâs deployment. Race and marital status had an effect on parental self-efficacy in the domain of academic achievement. Race had a small effect on parental self-efficacy in the discipline domain. The hardship of deployment may potentially have a higher impact on military spouses managing extra responsibilities, financial hardships, and added pressure to support the academic needs of their children
Verbal compounding in Latin: the case of -MAKE verbs
This paper aims at describing Latin compound verbs (CVs) whose second member is a verbal constituent connected with facio âto makeâ. Though there is a large literature on CVs in other languages, little has been said on Latin (Flobert 1978; Fruyt 2001 inter al.).
CVs are extremely interesting in several respects. First, compared to Latin nominal compounds, whose core consists of exocentric formations, -MAKE CVs are endocentric constructions (Brucale 2012). Second, they represent an island of productivity in the generally unproductive area of verbal compounding in Latin. Third, they can be compared to analogous constructions in other Indo-European languages, viz. Persian and Hindi, which exhibit the same pattern.
Two subclasses of -MAKE CVs can be found:
1) -fico verbs, whose first constituent can be either a noun, e.g. aedifico âto erect a buildingâ, or an adjective, e.g. beatifico âto make happyâ. In the former case, the noun is syntactically the direct internal argument of the verb. In the latter, the adjective has a predicative function and the compound conveys the causative meaning âmake Qâ (or âfactitiveâ, Lehmann fc.), where Q is a quality/state/condition (Kulikov 2001).
2) -facio verbs, which includes many types of compounds, the most productive of which is the so-called Causative subtype (Hahn 1947). This subtype is further divisible into three classes:
a) CVs quite regularly connected to intransitive verbs in -eo (e.g. caleo âto be hotâ) denoting states/conditions. This type is particularly productive and is used in causative CVs (e.g. calefacio âto make hotâ), sharing with the -fico compounds above the meaning âmake Qâ.
b) CVs in which the presence of facio does not yield any causative meaning nor introduces any semantic change in the first member, which already possesses a causative meaning, e.g. perterrefacio âto terrifyâ.
c) compounds not related to any existent verb in -eo:
- CVs connected with inchoative -sco verbs (e.g. assuesco âto become accustomedâ/assuefacio âto accustomâ). These are often âlabile verbsâ which can be employed both as causatives and corresponding non-causatives with no overt formal change in the verb. The meaning of the corresponding -facio CV, therefore, will equal the meaning at work in the causative use of the verb in the first member.
- CVs involving verbs of 1st (e.g. maturo âto ripenâ/maturefacio âto ripenâ) and 3rd conjugation (e.g. expergo âto arouseâ/expergefacio âto arouseâ). In this group are listed many causative verbs whose meaning is not altered by the compounding operation with âfacio.
In this work, we intend to provide an accurate description of the range of Latin -MAKE CVs, in order to find a rationale allowing for a perspicuous classification of these data. In particular, we attempt to clarify the morpho-syntactic status of causative CVs, and to further investigate which kind of causativization strategies they instantiate (Lehmann fc).

The semantic network of the Latin preposition per: a diachronic investigation.
This paper explores the semantic network of the Latin preposition per (âthroughâ) in a diachronic perspective derived from the analysis of two electronic corpora of 3rd century BCE â 4th century CE (PHI5; Intratext Digital Library). Drawing upon the insights of Cognitive Grammar (e.g. Langacker 1991), we analyze the role of the schematic import of per in the spread from basic to abstract meanings, thus accounting for the interconnections among the various senses of the polysemous entity. This theoretical position is integrated with Croftâs (1991) model of causal structure of events, as well as the results of an extensive analysis of Early Latin (Brucale & Mocciaro fc.), in order to address the following issues:
1. the diachronic shifts in the ratio of spatial to abstract meanings: spatial meanings are predominant in Early Latin (e.g. per urbem ire, Pl., Poen 522; per cribrum transire, Cat., De Agr. 76.3.4), while the only abstract values which are fully grammaticalized at this stage are MEANS (a less prototypical and abstract instrument: per vim retinere, Pl., Bacch. 843; see Croft 1991: 178) and REASON (the motivation for an agent to act: per metum mussari, Pl., Aul. 131; see Pinkster 1990). We aim at tracing back the path(s) through which new abstract meanings arise.
2. the role of Animacy: MEANS and REASON involve non-animate (abstract) participants, whereas the spread to Animacy represents a secondary development within the area of Causation, documented in Early Latin in a few instances of CAUSE (the motivation of a non- agentive event: per aliquem vivere, Pl., Poen. 1187) and INTERMEDIARY (per me interpretem, Pl., Mil. 910). Out of the causal domain, however,, Animacy is a rather ancient feature, represented in the expressions of Appeal (with performative verbs such as iuro, e.g. per Iovem iurare, Pl. Amph. 435) and Judgment of licitness (per me licet, Pl., Merc., 989). On the other hand, the expression of (concrete) INSTRUMENT represents a later development (cf. Luraghi 2010: per nauiculam uenire, Itala, cod. d., Ioh. 21, 8). In other words, the spread from concrete to abstract meanings appears to be non-unidirectional, rather drawing the following trajectory: SPATIAL (CONCRETE) > ABSTRACT > ANIMATE > INANIMATE (CONCRETE). 3. the grammaticalization of the expression of PURPOSE: another later development, which is based on an extension of Reason: âThe objects we aspire for are usually also the cause for our aspirationâ (Radden 1989: 562; see also Croft 1991: 293).
Finally we propose a semantic map of the range of values conveyed by per, showing that they do not arrange on a linear continuum, but rather represent a multi-directional configuration originating from the progressive (metonymical) extension of a prototypical nucleus over time.

Early changes in brain structure correlate with language outcomes in children with neonatal encephalopathy.
Global patterns of brain injury correlate with motor, cognitive, and language outcomes in survivors of neonatal encephalopathy (NE). However, it is still unclear whether local changes in brain structure predict specific deficits. We therefore examined whether differences in brain structure at 6Â months of age are associated with neurodevelopmental outcomes in this population. We enrolled 32 children with NE, performed structural brain MR imaging at 6Â months, and assessed neurodevelopmental outcomes at 30Â months. All subjects underwent T1-weighted imaging at 3Â T using a 3D IR-SPGR sequence. Images were normalized in intensity and nonlinearly registered to a template constructed specifically for this population, creating a deformation field map. We then used deformation based morphometry (DBM) to correlate variation in the local volume of gray and white matter with composite scores on the Bayley Scales of Infant and Toddler Development (Bayley-III) at 30Â months. Our general linear model included gestational age, sex, birth weight, and treatment with hypothermia as covariates. Regional brain volume was significantly associated with language scores, particularly in perisylvian cortical regions including the left supramarginal gyrus, posterior superior and middle temporal gyri, and right insula, as well as inferior frontoparietal subcortical white matter. We did not find significant correlations between regional brain volume and motor or cognitive scale scores. We conclude that, in children with a history of NE, local changes in the volume of perisylvian gray and white matter at 6Â months are correlated with language outcome at 30Â months. Quantitative measures of brain volume on early MRI may help identify infants at risk for poor language outcomes
Boundary Conditions for the Einstein Evolution System
New boundary conditions are constructed and tested numerically for a general
first-order form of the Einstein evolution system. These conditions prevent
constraint violations from entering the computational domain through timelike
boundaries, allow the simulation of isolated systems by preventing physical
gravitational waves from entering the computational domain, and are designed to
be compatible with the fixed-gauge evolutions used here. These new boundary
conditions are shown to be effective in limiting the growth of constraints in
3D non-linear numerical evolutions of dynamical black-hole spacetimes.Comment: 21 pages, 12 figures, submitted to PR
