Objective:
Agitation is a common neuropsychiatric symptom within the dementia spectrum, experienced by 70 percent of individuals with cognitive decline. Prior literature demonstrates a strong association between care recipient agitation and burden in caregivers of individuals with dementia, as these symptoms are often difficult to manage and predict. Understanding how agitation symptoms in the person with dementia may influence caregiver burden is imperative given these strong associations; however, both agitation and burden are complex, multidimensional constructs. Agitation in dementia involves a range of behaviors including increased motor activity, emotional distress, and aggressive behaviors. Caregiver burden is also multi-faceted and often incorporates dimensions of social/relationship, emotional, and physical health strain. The current study sought to determine whether specific presentations of agitation differentially relate to distinct patterns of caregiver burden.
Participants and Methods:Medical record data from an outpatient memory clinic were extracted for 609 persons with dementia and their caregivers. Caregivers completed the Zarit Burden Interview (ZBI) to assess caregiver burden and the Cohen-Mansfield Agitation Inventory (CMAI) to assess care recipient agitation behaviors. At their initial outpatient appointment, care recipients were also administered a measure of global cognitive functioning (either the Montreal Cognitive Assessment or the Mini-Mental State Examination). Demographic information was extracted from medical records. Exploratory factor analysis was used to determine ZBI and CMAI factor structures. Hierarchical multiple regression analyses then examined whether factors of the CMAI differentially predicted ZBI factors, controlling for dementia severity and demographic variables.
Results:Exploratory factor analysis yielded three domains of agitation on the CMAI ("Physically Aggressive," "Physically NonAggressive," "Verbally Agitated") and four domains of burden on the ZBI ("Impact on Life," "Guilt/Uncertainty," "Embarrassed/Frustrated," and "Overwhelm"). Regression analyses demonstrated all domains of agitation positively predicted overall burden. Regarding specific aspects of burden, Physically Aggressive behaviors predicted only Embarrassment/Frustration (B=.41, SE=.10, ß=.16, p<.001). Non-Aggressive behaviors predicted Impact on Life (B=.14, SE=.05, ß=.13, p<.01) and Guilt/Uncertainty (B=.05, SE=.02, ß=.10, p<.05). Verbally Agitated behaviors predicted all burden dimensions: Impact on Life (B=.35, SE=.06, ß=.32, p<.001), Guilt/Uncertainty (B=.12, SE=.03, ß=.22, p<.001), Embarrassment/Frustration (B=.17, SE=.02, ß=.38, p<.001), and Overwhelm (B=.16, SE=.02, ß=.40, p<.001).
Conclusions:Findings enhance understanding of the relationships between specific agitation symptoms and distinctive aspects of caregiver burden, suggesting that targeted interventions for aspects of caregiver burden based on agitation symptoms may be useful in alleviating burden. Interventions focused on caregivers' feelings of guilt, personal health decline, lack of time for themselves, and fear and uncertainty about the future may be effective when care recipients present with physically nonaggressive behaviors (e.g., pacing, restlessness, inappropriate dress or disrobing). When a care recipient presents with physically aggressive behaviors, helping the caregiver cope with embarrassment or anger may be of benefit. When a care recipient presents with verbally agitated behaviors, interventions targeting burden globally may be most useful. Future work should seek to replicate the current findings and explore such interventions.

Boyer's formulation neglects that humans are embodied agents. It is a biological imperative to distinguish self from other. Ownership of ideas, bodies, objects, and locations is an inevitable extension of this. We argue that (1) the body's capability influences the inputs that guide future actions, and (2) bodies in action influence all of cognition, from perception to decision making.

Multi-messenger observations of the transient sky to detect cosmic explosions and counterparts of gravitational wave mergers critically rely on orbiting wide-FoV telescopes to cover the wide range of wavelengths where atmospheric absorption and emission limit the use of ground facilities. Thanks to continuing technological improvements, miniaturised space instruments operating as distributed-aperture constellations are offering new capabilities for the study of high-energy transients to complement ageing existing satellites. In this paper we characterise the performance of the upcoming joint SpIRIT and HERMES-TP/SP constellation for the localisation of high-energy transients through triangulation of signal arrival times. SpIRIT is an Australian technology and science demonstrator satellite designed to operate in a low-Earth Sun-synchronous Polar orbit that will augment the science operations for the equatorial HERMES-TP/SP constellation. In this work we simulate the improvement to the localisation capabilities of the HERMES-TP/SP constellation when SpIRIT is included in an orbital plane nearly perpendicular (inclination = 97.6°) to the HERMES-TP/SP orbits. For the fraction of GRBs detected by three of the HERMES satellites plus SpIRIT, we find that the combined constellation is capable of localising 60% of long GRBs to within ${\sim}30\,\textrm{deg}^{2}$ on the sky, and 60% of short GRBs within ${\sim}1850\,\textrm{deg}^{2}$ ($1\sigma$ confidence regions), though it is beyond the scope of this work to characterise or rule out systematic uncertainty of the same order of magnitude. Based purely on statistical GRB localisation capabilities (i.e., excluding systematic uncertainties and sky coverage), these figures for long GRBs are comparable to those reported by the Fermi Gamma Burst Monitor instrument. These localisation statistics represents a reduction of the uncertainty for the burst localisation region for both long and short GRBs by a factor of ${\sim}5$ compared to the HERMES-TP/SP alone. Further improvements by an additional factor of 2 (or 4) can be achieved by launching an additional 4 (or 6) SpIRIT-like satellites into a Polar orbit, respectively, which would both increase the fraction of sky covered by multiple satellite elements, and also enable localisation of ${\geq} 60\%$ of long GRBs to within a radius of ${\sim}1.5^{\circ}$ (statistical uncertainty) on the sky, clearly demonstrating the value of a distributed all-sky high-energy transient monitor composed of nano-satellites.

In this paper, we describe the system design and capabilities of the Australian Square Kilometre Array Pathfinder (ASKAP) radio telescope at the conclusion of its construction project and commencement of science operations. ASKAP is one of the first radio telescopes to deploy phased array feed (PAF) technology on a large scale, giving it an instantaneous field of view that covers $31\,\textrm{deg}^{2}$ at $800\,\textrm{MHz}$. As a two-dimensional array of 36$\times$12 m antennas, with baselines ranging from 22 m to 6 km, ASKAP also has excellent snapshot imaging capability and 10 arcsec resolution. This, combined with 288 MHz of instantaneous bandwidth and a unique third axis of rotation on each antenna, gives ASKAP the capability to create high dynamic range images of large sky areas very quickly. It is an excellent telescope for surveys between 700 and $1800\,\textrm{MHz}$ and is expected to facilitate great advances in our understanding of galaxy formation, cosmology, and radio transients while opening new parameter space for discovery of the unknown.

JET experiments have compared the efficacy of low- and high-field side ion cyclotron resonance heating (ICRH) as an actuator to deliberately minimise the sawtooth period. It is found that low-field side ICRH with low minority concentration is optimal for sawtooth control for two main reasons. Firstly, low-field side heating means that any toroidal phasing of the ICRH ($-90^{\circ }$, $+90^{\circ }$ or dipole) has a destabilising effect on the sawteeth, meaning that dipole phasing can be employed, since this is preferable due to less plasma wall interaction from Resonant Frequency (RF) sheaths. Secondly, the resonance position of the low-field side ICRH does not have to be very accurately placed to achieve sawtooth control, relaxing the requirement for real-time control of the RF frequency. These empirical observations have been confirmed by hybrid kinetic–magnetohydrodynamic modelling, and suggest that the ICRH antenna design for ITER is well positioned to provide a control actuator capable of having a significant effect on the sawtooth behaviour.

The present study compared executive dysfunction among children with attention-deficit/hyperactivity disorder (ADHD) after traumatic brain injury (TBI), also called secondary ADHD (S-ADHD), pre-injury ADHD and children with TBI only (i.e., no ADHD). Youth aged 6–16 years admitted for TBI to five trauma centers were enrolled (n=177) and evaluated with a semi-structured psychiatric interview scheduled on three occasions (within 2 weeks of TBI, i.e., baseline assessment for pre-injury status; 6-months and 12-months post-TBI). This permitted the determination of 6- and 12-month post-injury classifications of membership in three mutually exclusive groups (S-ADHD; pre-injury ADHD; TBI-only). Several executive control measures were administered. Unremitted S-ADHD was present in 17/141 (12%) children at the 6-month assessment, and in 14/125 (11%) children at 12-months post-injury. The study found that children with S-ADHD exhibited deficient working memory, attention, and psychomotor speed as compared to children with pre-injury ADHD. Furthermore, the children with S-ADHD and the children with TBI-only were impaired compared to the children with pre-injury ADHD with regard to planning. No group differences related to response inhibition emerged. Age, but not injury severity, gender, or adaptive functioning was related to executive function outcome. Neuropsychological sequelae distinguish among children who develop S-ADHD following TBI and those with TBI only. Moreover, there appears to be a different pattern of executive control performance in those who develop S-ADHD than in children with pre-injury ADHD suggesting that differences exist in the underlying neural mechanisms that define each disorder, underscoring the need to identify targeted treatment interventions.

This paper describes the system architecture of a newly constructed radio telescope – the Boolardy engineering test array, which is a prototype of the Australian square kilometre array pathfinder telescope. Phased array feed technology is used to form multiple simultaneous beams per antenna, providing astronomers with unprecedented survey speed. The test array described here is a six-antenna interferometer, fitted with prototype signal processing hardware capable of forming at least nine dual-polarisation beams simultaneously, allowing several square degrees to be imaged in a single pointed observation. The main purpose of the test array is to develop beamforming and wide-field calibration methods for use with the full telescope, but it will also be capable of limited early science demonstrations.

Varying degrees of ovarian development were induced in overwintered Dendroctonus pseudotsugae Hopk., put on (1) host logs, (2) bark chips, or (3) moist glass paper. In 96 hours the ovaries of beetles on logs reached maturation, those on bark chips showed only slight growth, and the third group failed to show any development.Farnesyl methyl ether induced significant ovarian development in beetles kept on bark chips or glass paper. It appears that production or release of gonadotrophic hormone is withheld in insects kept outside their natural gallery environment. Sensory input associated with gallery excavation may initiate ovary development by stimulating endocrine activity.

Questions concerning the lengths of factorizations into irreducible elements in numerical monoids have gained much attention in the recent literature. In this note, we show that a numerical monoid has an element with two different irreducible factorizations of the same length if and only if its embedding dimension is greater than two. We find formulas in embedding dimension three for the smallest element with two different irreducible factorizations of the same length and the largest element whose different irreducible factorizations all have distinct lengths. We show that these formulas do not naturally extend to higher embedding dimensions.

Background:
This study aimed to determine the prevalence of pain, and the adequacy of its treatment, amongst patients with head and neck cancer, and to determine whether specific groups could be identified as being at risk of pain.
Methods:Consecutive patients attending head and neck oncology out-patient services were surveyed.
Results:The prevalence of pain was 34 per cent, lower than that found in systematic reviews. No specific risk factors for pain were identified. Particular pain problems in this population comprised a high incidence of neuropathic pain, breakthrough pain and pain of non-malignant origin.
Conclusion:The prevalence of unrelieved pain was high in this study population, although no specific risk factors were found. A further study is planned to determine the effect of using a routine screening tool and an immediate pain treatment protocol in this group of patients.

A low activity mutant of glucose-6-phosphate dehydrogenase, G6pda-m1Neu has been used to position G6pd in the mouse X chromosome. Linkage tests with tabby, Ta and harlequin, Hq, indicate a likely gene order of Hq–G6pd–Ta. Muscular dystrophy, mdx, has been located by two-and three-point crosses using Hprt, Pgk-1 and Moblo and suggest a gene order of Hprt–mdx–Pgk-1–Moblo. Together with existing linkage data a tentative order for the seven loci is Hq–Hprt–G6pd–mdx–Ta–Pgk-1–Moblo. The relative positions of G6pd and mdx have not been directly tested and G6pd is assigned provisionally proximal to mdx. In the three point test using Hq, G6pd and Ta the recombination frequency found between Hq and Ta was 9·9 ± 2·6%, substantially less than the value of 20·5 ± 2·1% reported by Isaacson et al. (1974).

Let M be a commutative cancellative atomic monoid. We consider the behaviour of the asymptotic length functions and on M. If M is finitely generated and reduced, then we present an algorithm for the computation of both and where x is a nonidentity element of M. We also explore the values that the functions and can attain when M is a Krull monoid with torsion divisor class group, and extend a well-known result of Zaks and Skula by showing how these values can be used to characterize when M is half-factorial.

The use of complex syntax was investigated in narrative language samples of older children and adolescents with Down syndrome (n = 24) and a group of typically developing children matched on mean length of utterance. Both groups used conjoined and subordinate sentence forms and did not differ significantly in either the proportion of utterances containing complex sentences or in the variety of complex sentence types used. The analysis of developmental patterns suggested a similar order of acquisition across groups. The findings indicate that syntactic development in individuals with Down syndrome continues into late adolescence and is not limited to simple syntax. This study does not support earlier findings of a critical period effect in syntactic development in Down syndrome based on age or syntactic complexity.

Background. This study was undertaken to examine the relationship between anxiety co-morbidity and age of onset of panic disorder.
Methods. Age of onset of panic disorder and co-morbid anxiety disorders were assessed among 201 panic disorder probands with childhood separation anxiety disorder, obsessive–compulsive disorder, obsessive–compulsive symptoms, social phobia and specific phobia as part of a clinician-administered lifetime diagnostic interview. A generalized linear model was used to test the association between each anxiety co-morbidity and age of panic disorder onset while simultaneously controlling for the potential confounding effects of sociodemographic characteristics and other psychiatric co-morbidity.
Results. Earlier onset of panic disorder was found in patients with co-morbid obsessive–compulsive disorder, obsessive–compulsive symptoms and separation anxiety disorder, but not simple phobia or social phobia. Patients with both childhood separation anxiety disorder and obsessive–compulsive disorder had an even earlier panic onset than those with either childhood separation anxiety disorder or obsessive–compulsive disorder.
Conclusions. The association between anxiety co-morbidity and earlier onset of panic disorder is specific to obsessive–compulsive disorder and childhood separation anxiety disorder.

Background. Previous studies of oculomotor dysfunction in schizophrenia have tended to concentrate on abnormalities of smooth pursuit eye tracking in chronic medicated patients. We report the results of a study of smooth pursuit, reflexive and antisaccade performance in drug naive and antipsychotic treated first-episode schizophrenic patients.
Methods. Smooth pursuit and saccadic eye movements were recorded in 36 first-episode schizophrenic patients and 36 controls matched for age and estimated IQ. The schizophrenic patients were divided into drug-naive (N=17) and antipsychotic treated groups (N=19).
Results. Smooth pursuit velocity gain was significantly lower than controls only in the drug-naive patients. The treated patients did not differ significantly from either the controls or the untreated group. In an antisaccade paradigm both treated and drug-naive schizophrenic patients demonstrated an increased number of errors, but only drug-naive patients also demonstrated an increased latency in initiating correct antisaccades.
Conclusions. These impairments are unlikely to be due to a generalized deficit in oculomotor function in the schizophrenic groups, as there were no differences between the groups in saccadic metrics on a reflexive saccade task. The results show that both smooth pursuit and saccadic abnormalities are present at the onset of schizophrenia and are integral to the disorder.
