Orthography plays a limited role when learning the phonological forms of new words: The case of Spanish and English learners of novel Dutch words
Authors: ESCUDERO PAOLA 
Published: January 2015

ABSTRACTSome previous studies have shown that the availability of orthographic information leads to positive effects for second language (L2) phonology, while others document negative effects. In this paper, we examine the role of orthography on novel spoken-word learning by comparing word pairs that differed in most or all of their segments (nonminimal pairs) and those that only differed in one phoneme (minimal pairs) that was considered easy or difficult to discriminate. We tested the performance of learners whose native languages have transparent orthographies as well as learners with opaque orthographies. Our findings show that regardless of linguistic background and native orthographic system, availability of orthographic information during word learning did not have an effect on nonminimal pairs or perceptually easy minimal pairs. However, it had a positive effect on two minimal pairs that had the highest accuracy among the seven perceptually difficult ones, indicating that orthography only helped contrasts that were relatively easy to discriminate. The implications of these findings for L2 teaching and for future directions within L2 phonology are discussed.
Effects of orthographic forms on pronunciation in experienced instructed second language learners
Authors: BASSETTI BENE , ATKINSON NATHAN 
Published: January 2015

ABSTRACTIn spite of burgeoning evidence that the orthographic forms (“spellings”) of second language (L2) words affect L2 learners’ pronunciation, little is known about the pronunciation of known words in experienced learners. In a series of four studies, we investigated various orthographic effects on the pronunciation of L2 English words in instructed learners with 10 years’ experience of learning English. Participants were native users of the phonologically transparent Italian writing system. Study 1 investigated the pronunciation of “silent letters,” using a word-reading task and a word-repetition task. Study 2 examined the effects of vowel spelling on vowel duration, namely, whether L2 speakers produce the same target vowel as longer when it is spelled with a vowel digraph than with a singleton letter. Study 3 explored the effects of the morphemic spelling of the past tense marker <ed> using a verb paradigm-production task. Study 4 tested whether L2 speakers produce homophonic words differently when they are spelled differently. Results confirmed that orthographic forms affect experienced instructed learners’ pronunciation of known words, albeit less so in immediate word repetition than in reading-aloud tasks.
Representation of second language phonology
Authors: CUTLER ANNE 
Published: January 2015

ABSTRACTOrthographies encode phonological information only at the level of words (chiefly, the information encoded concerns phonetic segments; in some cases, tonal information or default stress may be encoded). Of primary interest to second language (L2) learners is whether orthography can assist in clarifying L2 phonological distinctions that are particularly difficult to perceive (e.g., where one native-language phonemic category captures two L2 categories). A review of spoken-word recognition evidence suggests that orthographic information can install knowledge of such a distinction in lexical representations but that this does not affect learners’ ability to perceive the phonemic distinction in speech. Words containing the difficult phonemes become even harder for L2 listeners to recognize, because perception maps less accurately to lexical content.

AbstractWe study when a pro-p subdirect product S ⩽ G1 × . . . × Gn is of type FPm for m ⩾ 2 for some special pro-p groups Gi. In particular we treat the case when Gi is a finitely generated non-trivial free pro-p product different from C2 ∐ C2 if p = 2 or a non-abelian pro-p group from the class $\mathcal{L}$ defined in [12].
Using linked birth, notification, hospital and mortality data to examine false-positive meningococcal disease reporting and adjust disease incidence estimates for children in New South Wales, Australia
Authors: GIBSON A. , JORM L. , McINTYRE P. 
Published: January 2015

SUMMARYMeningococcal disease is a rare, rapidly progressing condition which may be difficult to diagnose, disproportionally affects children, and has high morbidity and mortality. Accurate incidence estimates are needed to monitor the effectiveness of vaccination and treatment. We used linked notification, hospital, mortality and birth data for all children of an Australian state (2000–2007) to estimate the incidence of meningococcal disease. A total of 595 cases were notified, 684 cases had a hospital diagnosis, and 26 cases died from meningococcal disease. All deaths were notified, but only 68% (466/684) of hospitalized cases. Of non-notified hospitalized cases with more than one clinical admission, most (90%, 103/114) did not have meningococcal disease recorded as their final diagnosis, consistent with initial ‘false-positive’ hospital meningococcal disease diagnosis. After adjusting for false-positive rates in hospital data, capture–recapture estimation suggested that up to four cases of meningococcal disease may not have been captured in either notification or hospital records. The estimated incidence of meningococcal disease in NSW-born and -resident children aged 0–14 years was 5·1–5·4 cases/100 000 child-years at risk, comparable to international estimates using similar methods, but lower than estimates based on hospital data.
The effects of violence exposure on the development of impulse control and future orientation across adolescence and early adulthood: Time-specific and generalized effects in a sample of juvenile offenders

Published: January 2015

AbstractImpulse control and future orientation increase across adolescence, but little is known about how contextual factors shape the development of these capacities. The present study investigates how stress exposure, operationalized as exposure to violence, alters the developmental pattern of impulse control and future orientation across adolescence and early adulthood. In a sample of 1,354 serious juvenile offenders, higher exposure to violence was associated with lower levels of future orientation at age 15 and suppressed development of future orientation from ages 15 to 25. Increases in witnessing violence or victimization were linked to declines in impulse control 1 year later, but only during adolescence. Thus, beyond previous experiences of exposure to violence, witnessing violence and victimization during adolescence conveys unique risk for suppressed development of self-regulation.
The emergence of co-occurring adolescent polysubstance use and depressive symptoms: A latent growth modeling approach

Published: January 2015

AbstractThis study tests competing models of the relation between depression and polysubstance use over the course of adolescence. Participants included a nationwide sample of adolescents (N = 3,604), ages 12 to 17 at study Wave 1, assessed annually for 3 years. Models were tested using cohort-sequential latent growth curve modeling to determine whether depressive symptoms at baseline predicted concurrent and age-related changes in drug use, whether drug use at baseline predicted concurrent and age-related changes in depressive symptoms, and whether initial levels of depression predicted changes in substance use significantly better than vice versa. The results suggest a transactional model such that early polysubstance use promotes early depressive symptoms, which in turn convey elevated risk for increasing polysubstance use over time, which in turn conveys additional risk for future depressive symptoms, even after accounting for gender, ethnicity, and household income. In contrast, early drug use did not portend risk for future depressive symptoms. These findings suggest a complicated pattern of interrelations over time and indicate that many current models of co-occurring polysubstance use and depressive symptoms may not fully account for these associations. Instead, the results suggest a developmental cascade, in which symptoms of one disorder promote symptoms of the other across intrapersonal domains.
Nitrate controls testa rupture and water content during release of physiological dormancy in seeds of Sisymbrium officinale (L.) Scop.
Authors: Toorop Peter E. 
Published: January 2015

AbstractSeeds of Sisymbrium officinale display physiological dormancy and require nitrate to germinate. Rupture of the testa precedes radicle protrusion through the endosperm (germination sensu stricto). While both endosperm rupture and testa rupture (TR) required nitrate, endosperm rupture was fully inhibited by abscisic acid (ABA) but TR was not inhibited. The gibberellic acid (GA)-synthesis inhibitor paclobutrazol prevented TR, which was reverted by exogenous GA4 but not by nitrate. The orientation of TR was transverse, which prompted the question whether seeds elongate prior to radicle protrusion, concurrent with an increase in water content. Between 9 h and 1 d no increase in length or water content was observed. During incubation in ABA the length of imbibed seeds without TR did not increase between 1 and 5 d, whereas nitrate added to ABA induced TR and a 94% increase in length. At the same time the water content of seeds without TR increased by 18%, while the water content of seeds with TR increased by 38%. Length and water content were correlated in a single-seed analysis for seeds with TR, but not for seeds without TR. Increased length was also observed in Arabidopsis seeds with nitrate-induced TR. These results indicate that prior to endosperm rupture dormancy release by nitrate is accompanied by TR, seed elongation and an increase in water content. A new multiphasic model is proposed for the imbibition curve, where the second phase of the classical triphasic curve is split into three sub-phases, of which phases IIB and IIC are associated with TR.
Are wildfires an adapted ecological cue breaking physical dormancy in the Mediterranean basin?
Authors: Jaganathan Ganesh K. 
Published: January 2015

AbstractMany studies have claimed that fire acts as the chief ecological factor cueing dormancy break in seeds with a water-impermeable seed coat, i.e. physical dormancy (PY), in Mediterranean ecosystems. However, a proposal is made that seasonal temperature changes must be viewed as more meaningful dormancy-breaking cues because: (1) fire is erratic and may break PY in seasons during which seedlings cannot complete their life cycle; (2) fire may not occur for long periods, thereby only providing an opportunity for dormancy break and germination once in every several years; and (3) if fire opens the specialized anatomical structures called ‘water gaps’, in seconds, their evolutionary role of detecting environmental conditions becomes irrational. Although fire breaks dormancy in a proportion of seeds, given the risk of seed mortality and the post-fire environment providing cues for dormancy break, it is suggested that fire might possibly be an exaptation.
A ‘social evil’: Liverpool moneylenders 1920s–1940s
Authors: FEARON PETER 
Published: January 2015

ABSTRACTDuring the 1920s and 1930s many working-class families needed emergency credit. Their use of pawnbrokers is well documented but the presence of a network of moneylenders, most of whom were women operating from their own homes, is not. This article examines the background to and the impact of the Moneylenders Act (1927) which was designed to reduce the number of working-class lenders, widely perceived as disreputable, in order to protect vulnerable borrowers, most of whom were women. Using Liverpool as a case-study, I also examine the possible reasons for the dramatic decline in the number of licensed moneylenders and analyse the implications of this for the provision of working-class credit.
Radiotherapy for histiocytic sarcoma: a case report
Authors: Bourgeois Daniel J. , Dixon Allison , Singh Anurag K. 
Published: January 2015

AbstractBackgroundHistiocystic sarcoma is a rare, but aggressive tumour that often involves extranodal sites. Histiocystic sarcoma is recognised by the World Health Organization as one of six subtypes of dendritic cell neoplasms. Diagnosis is difficult due to overlapping immunohistochemistry with other dendritic cell neoplasms. The optimal roles for chemotherapy, radiotherapy and surgery in the treatment of histiocytic sarcoma remain unknown.MethodsWe report a case of a patient with histiocytic sarcoma diagnosed after excisional biopsy and immunohistochemistry testing.ResultsThe patient underwent external beam radiation therapy (EBRT). After 18 Gray (Gy), the 8 cm lesion had regressed to ~5 cm in diameter. The treatments were continued to a total dose of 45 Gy with the lesion regressing to less than a centimeter by the end of treatment. Local control was maintained but the patient died of acute myelogenous leukemia 5 months after her treatment.ConclusionsThis case suggests that histicytic sarcomas can be controlled locally with EBRT.
Psycho-oncology: Searching for practical wisdom?
Authors: Butlin Helen 
Published: January 2015

AbstractThe debate is vigorous in psycho-oncology about whetherspiritual,existential, andpsychosocialare the most comprehensive terms for academic research discourses investigating meaning and purpose. A call-to-action email from the International Society of Psycho-Oncology included the termsoul. The current essay highlights the historical and contemporary uses of “soul” to suggest that the re-emergentsoulsignifies a tacit quest for an “intangible” that seems missing in current constructs of clinical domains reflected in the vigor of the debates. It is suggested that the re-emergence of the pre-Medieval meaning(s) of the notion ofsoulaffirms a growing need for integrative paradigms on “being human” to guide psycho-oncology practitioners and their research. As a paradigmatic example, a clinical support group entitledSoul Medicineis described as employing the termsoulto open up the more marginal discourses about experiences of illness arising from philosophical reflection, arts, humanities, and spirituality within a clinical oncology context. A link betweensoulandwisdomis suggested for further exploration with the view thatphronesis(“the virtue of practical wisdom”), an emerging concept in health professional education research, is of ultimate value to the people psycho-oncology seeks to serve. This group holds that garnering wisdom from the expertise of those living with cancer should be a central aim of our field.
On the margins of health economics: a response to ‘resolving NICE’S nasty dilemma’
Authors: Birch Stephen , Gafni Amiram 
Published: January 2015

AbstractIn a 2011 article published in this journal, Baker et al. set out to resolve a nasty dilemma for NICE by reconciling two approaches for determining whether adopting a new intervention would increase total health gains produced from available resources and hence increase system efficiency. In this response we show how the proposed reconciliation, as well as the two approaches on which it is based, fail to inform decision makers about the efficiency of a new intervention. We show how this arises from the misuse of incremental costs and effects of between-intervention comparisons as measures of changes in costs and effects associated with marginal adjustments to the scale of an intervention. Ironically, incremental data represent the choices faced by decision makers and we illustrate a method for determining unambiguously whether a new intervention represents an improvement in efficiency.
CONTINGENCY AND KNOWING WHETHER
Authors: FAN JIE , WANG YANJING , DITMARSCH HANS VAN 
Published: January 2015

AbstractA proposition is noncontingent, if it is necessarily true or it is necessarily false. In an epistemic context, ‘a proposition is noncontingent’ means that you knowwhetherthe proposition is true. In this paper, we study contingency logic with the noncontingency operator Δ but without the necessity operator □. This logic is not a normal modal logic, because Δ(φ→ψ) → (Δφ→ Δψ) is not valid. Contingency logic cannot define many usual frame properties, and its expressive power is weaker than that of basic modal logic over classes of models without reflexivity. These features make axiomatizing contingency logics nontrivial, especially for the axiomatization oversymmetricframes. In this paper, we axiomatize contingency logics over various frame classes using a novel method other than the methods provided in the literature, based on the ‘almost-definability’ schema AD proposed in our previous work. We also present extensions of contingency logic with dynamic operators. Finally, we compare our work to the related work in the fields of contingency logic and ignorance logic, where the two research communities have similar results but are apparently unaware of each other’s work. One goal of our paper is to bridge this gap.
Bandwidth enhancement of capacitive fed monopole antenna using parasitic patches
Authors: Ayyadurai Kamalaveni , Muthu Ganesh Madhan 
Published: January 2015

This paper proposed a compact planar monopole antenna operating at 5 GHz (5.180–5.825 GHz) industrial, scientific and medical (ISM) radio band. The antenna constructed with 20 mm × 12 mm radiating element and 25 mm square of the ground plane in FR4 substrate provided −10 dB bandwidth of 1 GHz (5.4–6.4 GHz). To improve the bandwidth, parasitic elements are added with the monopole antenna. A capacitive feed is also incorporated in the design. It observed that the proposed antenna with parasitic elements provides a larger impedance bandwidth of about 3 GHz (5.1–8.1 GHz), which is three-fold improvements over the one without parasitic patches. The prototype of the antenna that operates at 5.8 GHz frequency range is fabricated and characterized using a near-field measurement system. A good agreement is found between the simulation and measured results.

Published: January 2015

Laterally diffused metal oxide semiconductor (LDMOS) transistors with 10 V breakdown voltage have been implemented in a 65 nm Complementary metal oxide semiconductor (CMOS) process without extra masks or process steps. Radio frequency (RF) performance for Wireless local area network (WLAN) frequencies and in X-band at 8 GHz is investigated by load-pull measurements in class AB operation for both 3.3 and 5 V supply voltage. Results at 2.45 GHz showed 290 mW/mm output power density with 17 dB linear gain and over 45% power added efficiency (PAE) at 4 dB compression at a supply voltage of 5 V. Furthermore, results in X-band at 8 GHz show 8 dB linear gain, 320 mW/mm output power density and over 22% PAE at 4 dB compression. Third-order intermodulation measurements at 8 GHz revealed OIP3 of 18.9 and 21.9 dBm at 3.3 and 5 V, respectively. The transistors were also tested for reliability which showed no drift in quiescent current after 26 h of DC stress while high-power RF stress showed only small extrapolated drift at 10 years in output power density. This is to the authors' knowledge the first time high output power density in X-band is demonstrated for integrated LDMOS transistors manufactured in a 65 nm CMOS process without extra process steps.
Pain-Related Attitudes and Functioning in Elderly Primary Care Patients

Published: January 2015

AbstractThis study examined the associations between specific pain-related beliefs and both mental health and pain interference in elderly patients with chronic pain. A total of 139 patients completed validated questionnaires assessing pain domains (i.e., intensity, duration and location), psychological functioning, pain interference and demographic variables. Pain-related beliefs were related with poorer mental health (Disability = –.27; Harm = –.23; Solicitude = –.24; Control = .18; Emotion = –.29) and greater interference in daily activities (Disability =.41; Harm =.13; Solicitude =.29; Control = –.31). Our findings are consistent with a biopsychosocial model of chronic pain which goes beyond physical variables in an attempt to understand and promote patients’ adjustment to chronic pain problems.
Interpersonal Self-Support and Attentional Disengagement from Emotional Faces

Published: January 2015

AbstractPrior studies have shown that interpersonal self-support is related to emotional symptoms. The present study explored the relationship between interpersonal self-support and attentional disengagement from emotional faces. A spatial cueing task was administrated to 21 high and 24 low interpersonal self-support Chinese undergraduate students to assess difficulty in shifting away from emotional faces. The Sidak corrected multiple pairwise tests revealed that the low interpersonal self-support group had greater response latencies on negative faces than neutral faces or positive faces in the invalid cues condition,F(2, 41) = 5.68,p< .01, η2= .22. In addition, in the invalid cues condition, the low interpersonal self-support group responded more slowly than the high interpersonal self-support group to negative faces,F(1, 42) = 7.63,p< .01, η2= .15, the 95% confidence interval for difference of reaction time from 16.30 to 104.70. The results support our hypotheses that low interpersonal self-support is related to difficulty disengaging from negative emotional information and suggest that interpersonal self-support may refer to emotional dispositions, especially negative emotional dispositions.
Aerobic and anaerobic nitrogen transformation processes in N2-fixing cyanobacterial aggregates

Published: January 2015

Abstract
Colonies of N2-fixing cyanobacteria are key players in supplying new nitrogen to the ocean, but the biological fate of this fixed nitrogen remains poorly constrained. Here, we report on aerobic and anaerobic microbial nitrogen transformation processes that co-occur within millimetre-sized cyanobacterial aggregates (Nodularia spumigena) collected in aerated surface waters in the Baltic Sea. Microelectrode profiles showed steep oxygen gradients inside the aggregates and the potential for nitrous oxide production in the aggregates’ anoxic centres. 15N-isotope labelling experiments and nutrient analyses revealed that N2 fixation, ammonification, nitrification, nitrate reduction to ammonium, denitrification and possibly anaerobic ammonium oxidation (anammox) can co-occur within these consortia. Thus, N. spumigena aggregates are potential sites of nitrogen gain, recycling and loss. Rates of nitrate reduction to ammonium and N2 were limited by low internal nitrification rates and low concentrations of nitrate in the ambient water. Presumably, patterns of N-transformation processes similar to those observed in this study arise also in other phytoplankton colonies, marine snow and fecal pellets. Anoxic microniches, as a pre-condition for anaerobic nitrogen transformations, may occur within large aggregates (⩾1 mm) even when suspended in fully oxygenated waters, whereas anoxia in small aggregates (&lt;1 to ⩾0.1 mm) may only arise in low-oxygenated waters (⩽25 μm). We propose that the net effect of aggregates on nitrogen loss is negligible in NO3−-depleted, fully oxygenated (surface) waters. In NO3−-enriched (&gt;1.5 μm), O2-depleted water layers, for example, in the chemocline of the Baltic Sea or the oceanic mesopelagic zone, aggregates may promote N-recycling and -loss processes.
