The Effect of Positive and Negative Pictures on the Processing of Emotion-Related Words

In our study, we wanted to test whether negative and positive stimuli affect lexical decision tasks. The participants consisted of 30 CSB/SJU students (14 males and 16 females). The participants saw either negative or positive pictures. After rating the various pictures, the participants’ reaction times to words and non-words was recorded to see how priming affected their reactions. We hypothesized that emotional priming would make a difference in their reaction times to words of different emotions (positive and negative). The results demonstrated that there was not an interaction between the picture group the participants were assigned to and their reaction times to the negative and positive words

Exploring the digital competence of pre-service teachers on entry onto an initial teacher education programme in Ireland

peer-reviewedThis study aimed to explore the digital competence of recent entrants into a pre-service teacher education programme in an Irish University. The participants were drawn from a cohort of 208 undergraduate teacher education students. The study employed an online survey that captured both self-reported levels of digital competence and knowledge of key areas of cyber ethics and digital technology. The respondents were active users of technology and very frequent users of social media but reported levels of skills in the use of other digital technologies was lower. In addition, their knowledge of cyber-ethics and associated practices varied. The study also found that they were positively disposed to technology in teaching. The paper argues that, while there are limitations to surveys that aim to capture one’s level of digital competence, they can help guide teacher educators in responding to pre-service teachers. However, digital competence is an evolving concept and care must be taken to ensure that frameworks and tools used to assess it do not stifle teachers’ autonomy in relation to their utilisation of technology

Masking release due to linguistic and phonetic dissimilarity between the target and masker speech

Purpose: To investigate masking release for speech maskers for linguistically and phonetically close (English and Dutch) and distant (English and Mandarin) language pairs. Method: Thirty-two monolingual speakers of English with normal audiometric thresholds participated in the study. Data are reported for an English sentence recognition task in English and for Dutch and Mandarin competing speech maskers (Experiment 1) and noise maskers (Experiment 2) that were matched either to the long-term average speech spectra or to the temporal modulations of the speech maskers from Experiment 1. Results: Listener performance increased as the target-tomasker linguistic distance increased (English-in-English < English-in-Dutch < English-in-Mandarin). Conclusion: Spectral differences between maskers can account for some, but not all, of the variation in performance between maskers; however, temporal differences did not seem to play a significant role

Topical Flunixin Meglumine Effects on Pain Associated Biomarkers after Dehorning

Twenty-four calves were dehorned and treated with either topical flunixin meglumine formulated for systemic absorption or a placebo. Biomarkers associated with pain were evaluated for up to 72 hour after the dehorning procedure. Plasma cortisol concentrations, 90 minutes post-dehorning, and mechanical nociception threshold at the control site were the only tested biomarkers where a significant difference was demonstrated. No other differences of biomarkers between the two dehorned groups were observed for any time points. Although this product is easy to dose and dispense, its effects on pain biomarkers appears to be negligible

Obstetric complications and intelligence in patients on the schizophrenia-bipolar spectrum and healthy participants

Background Whether severe obstetric complications (OCs), which harm neural function in offspring, contribute to impaired cognition found in psychiatric disorders is currently unknown. Here, we sought to evaluate how a history of severe OCs is associated with cognitive functioning, indicated by Intelligence Quotient (IQ). Methods We evaluated the associations of a history of OCs and IQ in 622 healthy controls (HC) and 870 patients on the schizophrenia (SCZ) – bipolar disorder (BIP) spectrum from the ongoing Thematically Organized Psychosis study cohort, Oslo, Norway. Participants underwent assessments using the NART (premorbid IQ) and the WASI (current IQ). Information about OCs was obtained from the Medical Birth Registry of Norway. Multiple linear regression models were used for analysis. Results Severe OCs were equally common across groups. SCZ patients with OCs had lower performances on both premorbid and current IQ measures, compared to those without OCs. However, having experienced more than one co-occurring severe OC was associated with lower current IQ in all groups. Conclusions Severe OCs were associated with lower IQ in the SCZ group and in the BIP and HC groups, but only if they had experienced more than one severe OC. Low IQ might be a neurodevelopmental marker for SCZ; wherein, severe OCs influence cognitive abilities and increase the risk of developing SCZ. Considering OCs as a variable of neurodevelopmental risk for severe mental illness may promote the development of neuroprotective interventions, improve outcome in vulnerable newborns and advance our ability to make clinical prognoses

Cost-effectiveness analysis of fidaxomicin versus vancomycin in <i>Clostridium difficile</i> infection

Fidaxomicin was non-inferior to vancomycin with respect to clinical cure rates in the treatment of Clostridium difficile infections (CDIs) in two Phase III trials, but was associated with significantly fewer recurrences than vancomycin. This economic analysis investigated the cost-effectiveness of fidaxomicin compared with vancomycin in patients with severe CDI and in patients with their first CDI recurrence. A 1 year time horizon Markov model with seven health states was developed from the perspective of Scottish public healthcare providers. Model inputs for effectiveness, resource use, direct costs and utilities were obtained from published sources and a Scottish expert panel. The main model outcome was the incremental cost-effectiveness ratio (ICER), expressed as cost per quality-adjusted life year (QALY), for fidaxomicin versus vancomycin; ICERs were interpreted using willingness-to-pay thresholds of A 20aEuroS000 pound/QALY and A 30aEuroS000 pound/QALY. One-way and probabilistic sensitivity analyses were performed. Total costs were similar with fidaxomicin and vancomycin in patients with severe CDI (A 14aEuroS515 pound and A 14aEuroS344 pound, respectively) and in patients with a first recurrence (A 16aEuroS535 pound and A 16aEuroS926 pound, respectively). Improvements in clinical outcomes with fidaxomicin resulted in small QALY gains versus vancomycin (severe CDI, +0.010; patients with first recurrence, +0.019). Fidaxomicin was cost-effective in severe CDI (ICER A 16aEuroS529 pound/QALY) and dominant (i.e. more effective and less costly) in patients with a first recurrence. The probability that fidaxomicin was cost-effective at a willingness-to-pay threshold of A 30aEuroS000 pound/QALY was 60% for severe CDI and 68% in a first recurrence. Fidaxomicin is cost-effective in patients with severe CDI and in patients with a first CDI recurrence versus vancomycin

Cross-accent intelligibility of speech in noise: Long-term familiarity and short-term familiarization

Listeners must cope with a great deal of variability in the speech signal, and thus theories of speech perception must also account for variability, which comes from a number of sources, including variation between accents. It is well-known that there is a processing cost when listening to speech in an accent other than one’s own, but recent work has suggested that this cost is reduced when listening to a familiar accent widely represented in the media, and/or when short amounts of exposure to an accent are provided. Little is known, however, about how these factors (long-term familiarity and short-term familiarization with an accent) interact. The current study tested this interaction by playing listeners difficult-to-segment sentences in noise, before and after a familiarization period where the same sentences were heard in the clear, allowing us to manipulate short-term familiarization. Listeners were speakers of either Glasgow English or Standard Southern British English, and they listened to speech in either their own or the other accent, thereby allowing us to manipulate long-term familiarity. Results suggest that both long-term familiarity and short-term familiarization mitigate the perceptual processing costs of listening to an accent that is not one’s own, but seem not to compensate for them entirely, even when the accent is widely heard in the media
