Attending to the distractor and old/new discriminations in negative priming

When participants ignore an irrelevant distractor they typically show impaired responding to that item if it becomes the relevant stimulus on a subsequent trial. In Experiment 1 (N = 64), a masked white colour name was presented briefly before a Stroop display. Negative priming in colour naming occurred when the colour of the lettering for the Stroop stimulus matched the colour name displayed in the first display, consistent with the proposal of temporal discrimination theory that negative priming arises because a recurrence of an unattended stimulus cannot readily be classified as old or new. Experiment 2 (N = 32) replicated negative priming in the interleaved-word display where participants had to name the red word from a pair of red and green words. In Experiment 3 (N = 32) and Experiment 4 (N = 28) the participants were required to attend to but not respond to the words in the prime display and name one of two interleaved words in the probe display. Negative priming was observed in this arrangement, consistent with the episodic retrieval theory of negative priming. The temporal discrimination model may need to be extended to situations in which the attended stimuli have different responses attached to them.

Verbal recall after mild traumatic brain injury: Sensitivity of the rapid screen of concussion

The present study aimed to determine whether including a sensitive test of immediate and delayed recall would improve the diagnostic validity of the Rapid Screen of Concussion (RSC) in mild Traumatic Brain Injury (mTBI) versus orthopaedic clinical samples. Two studies were undertaken. In Study 1, the performance of 156 mTBI and 145 orthopaedic participants was analysed to identify the number of individuals who performed at ceiling on the verbal memory subtest of the RSC, as this test required immediate and delayed recall of only five words. A second aim was to determine the sensitivity and specificity levels of the RSC. Study 2 aimed to examine whether replacement of the verbal memory subtest with the 12-word Hopkins Verbal Learning Test (HVLT) could improve the sensitivity of the RSC in a new sample of 26 mTBI and 30 orthopaedic participants. Both studies showed that orthopaedic participants outperformed mTBI participants on each of the selected measures. Study 1 showed that 14% of mTBI participants performed at ceiling on the immediate and 21.2% on delayed recall test. Performance on the original battery yielded a sensitivity of 82%, specificity of 80% and overall correct classification of 81.5% participants. In Study 2, inclusion of the HVLT improved sensitivity to a level of 88.5%, decreased specificity to a level of 70% and resulted in an overall classification rate of 80%. It was concluded that although inclusion of the five-word subtest in the RSC can successfully distinguish concussed from non-concussed individuals, use of the HVLT in this protocol yields a more sensitive measure of subtle cognitive deficits following mTBI.

The rellationship between specific features of aphasia-friendly written material and comprehension of written material for people with aphasia: An exploratory study

Background: Written material is often inaccessible fro people with aphasia. The format of written material needs to be adapted to enable people with aphasia to read with understanding. Aims: This study aimed to further explore some issues raised in Rose, Worrall, and MacKenna (2003) concerning the effects of aphasia-friendly formats on the reading comprehension of people with aphasia. It was hypothesised that people with aphasia would comprehend significantly more paragraphs that were formatted in an aphasia-friendly manner than control paragraphs. This study also aimed to investigate if each single aspect of aphasia-friendly formatting (i.e., simplified vocabulary and syntax, large print, increased white spacem and pictures) used in isolation would result in increased comprehension compared to control paragraphs. Other aims were to compare the effect of aphasia-friendly fromatting with the effects of each single adaptation, and to investigate if the effects of aphasia-friendly formates were related to aphasia severity. Methods & Procedures: Participants with mild to moderately severe aphasia (N = 9) read a battery of 90 paragraphs and selected the best word of phrase from a choice of four to complete each paragraph. A linear mixed model (p < .05) was used to analyse the differences in reading comprehension with each paragraph fromat across three reading grade levels. Outcomes & Results: People with aphasia comprehended significantly more aphasia-friendly paragraphs than control paragraphs. They also comprehended significantly more paragraphs with each of the following single adaptations: simplified vocabulary and syntax, large ptint, and increased white spaces. Although people with aphasia tended to comprehend more paragraphs with pictures added than control paragraphs, this difference was not significant. No significant correlation between aphasia severity and the effect of aphasia-friendly formatting was found. Conclusion: This study supports the idea that aphasia-friendly formats increase the reading comprehension of people with aphasia. It suggests that adding pictures, particularly Clip Art pictures, may not significantly improve the reading the reading comprehension of people with aphasia. These findings have implications for all written communication with people with aphasia, both in the clinical setting and in the wider community. Applying these findings may enable people with aphasia to have equal access to written information and to participate in society.

The mode of action of the plant antimicrobial peptide MiAMP1 differs from that of its structural homologue, the yeast killer toxin WmKT

The plant antimicrobial peptide MiAMP1 from Macadamia integrifolia and the yeast killer toxin peptide WmKT from Williopsis mrakii are structural homologues. Comparative studies of yeast mutants were performed to test their sensitivity to these two antimicrobial peptides. No differences in susceptibility to MiAMP1 were detected between wild-type and several WmKT-resistant mutant yeast strains. A yeast mutant MT1, resistant to MiAMP1 but unaffected in its susceptibility to plant defensins and hydrogen peroxide, also did not show enhanced tolerance towards WmKT. It is therefore probable that the Greek key beta-barrel structure shared by MiAMP1 and WmKT provides a robust structural framework ensuring stability for the two proteins but that the specific action of the peptides depends on other motifs.

The influence of dopamine on semantic activation in Parkinson's disease: Evidence from a multipriming task

Research has suggested that semantic processing deficits in Parkinson's disease (PD) are related to striatal dopamine deficiency. As an investigation of the influence of dopamine on semantic activation in PD, 7 participants with PD performed a lexical-decision task when on and off levodopa medication. Seven healthy controls matched to the participants with PD in terms of sex, age, and education also participated in the study. By use of a multipriming paradigm, whereby 2 prime words were presented prior to the target word, semantic priming effects were measured across stimulus onset asynchronies (SOAs) of 250 Ins and 1,200 Ins. The results revealed a similar pattern of priming across SOAs for the control group and the PD participants on medication. In contrast, within-group comparisons revealed that automatic semantic activation was compromised in PD participants when off medication. The implications of these results for the neuromodulatory influence of dopamine on semantic processing in PD are discussed.

Reduplication and word stress in Vietnamese

In this paper acoustic properties of two types of reduplicative compound (full and tone sandhi reduplications) were examined to show acoustic evidence of assymetrical prominence relations (van der Hulst, 2005), in support of a hypothesis that Vietnamese reduplications are phonetically right headed and that tone sandhi is a reduction phenomenon occurring on prosodically weak positions (Shih, 2005). The results show phonetic evidence of prosodic constituency at the level of the bisyllabic word in Vietnamese.

A RENÚNCIA SEXUAL PELO REINO: A IMPORTÂNCIA DA RENÚNCIA SEXUAL PARA A LIDERANÇA DA MULHER EM ATOS DE PAULO E TECLA

O propósito desta pesquisa é analisar a obra os Atos de Paulo e Tecla, focando na importância da renúncia sexual para a liderança da mulher. Tema este que se tornou fundamental para que as mulheres conseguissem conquistar seu espaço e poder diante da sociedade e assim conseguir fazer com que sua voz fosse ouvida, mesmo que de forma não tão considerável. Ao examinar os Apócrifos Atos de Paulo e Tecla, pôde-se observar suas principais características e composição, apresentando sua origem e interpretação pelas comunidades e pelos líderes do início do cristianismo. Buscou-se nesta pesquisa retratar e fundamentar o romance grego, apresentando suas similaridades com os Atos de Paulo e Tecla, e desta maneira destacar a influência do escrito grego sobre o texto apócrifo em sua forma de estruturação. Apresentamos as definições sobre a renúncia sexual, liderança e martírio sempre destacando os temas com a figura da mulher, abordando a questão do corpo e a sociedade e demonstrando como estes temas inspiraram os discursos no início do cristianismo. Referente aos escritos dos Atos Apócrifos, apresentamos a origem das comunidades de mulheres celibatárias, que influenciaram a escrita dos textos, relatando o motivo pelo qual os Atos foram escritos e como foram disseminados nas outras comunidades. Sobre o martírio, descrevemos suas origens e como os cristãos viam nessa ação uma aproximação com Deus, e como o martírio preparou a vida de Tecla para que ela se tornasse uma anunciante da palavra de Deus.

The belief in TAP

We show the similarity between belief propagation and TAP, for decoding corrupted messages encoded by Sourlas's method. The latter is a special case of the Gallager error- correcting code, where the code word comprises products of K bits selected randomly from the original message. We examine the efficacy of solutions obtained by the two methods for various values of K and show that solutions for K>=3 may be sensitive to the choice of initial conditions in the case of unbiased patterns. Good approximations are obtained generally for K=2 and for biased patterns in the case of K>=3, especially when Nishimori's temperature is being used.

Activation of the left inferior frontal gyrus in the first 200 ms of reading:evidence from magnetoencephalography (MEG)

Background - It is well established that the left inferior frontal gyrus plays a key role in the cerebral cortical network that supports reading and visual word recognition. Less clear is when in time this contribution begins. We used magnetoencephalography (MEG), which has both good spatial and excellent temporal resolution, to address this question. Methodology/Principal Findings - MEG data were recorded during a passive viewing paradigm, chosen to emphasize the stimulus-driven component of the cortical response, in which right-handed participants were presented words, consonant strings, and unfamiliar faces to central vision. Time-frequency analyses showed a left-lateralized inferior frontal gyrus (pars opercularis) response to words between 100–250 ms in the beta frequency band that was significantly stronger than the response to consonant strings or faces. The left inferior frontal gyrus response to words peaked at ~130 ms. This response was significantly later in time than the left middle occipital gyrus, which peaked at ~115 ms, but not significantly different from the peak response in the left mid fusiform gyrus, which peaked at ~140 ms, at a location coincident with the fMRI–defined visual word form area (VWFA). Significant responses were also detected to words in other parts of the reading network, including the anterior middle temporal gyrus, the left posterior middle temporal gyrus, the angular and supramarginal gyri, and the left superior temporal gyrus. Conclusions/Significance - These findings suggest very early interactions between the vision and language domains during visual word recognition, with speech motor areas being activated at the same time as the orthographic word-form is being resolved within the fusiform gyrus. This challenges the conventional view of a temporally serial processing sequence for visual word recognition in which letter forms are initially decoded, interact with their phonological and semantic representations, and only then gain access to a speech code.

Exploring the impact of e-business adoption on logistics processes:empirical evidence from the food industry

The objectives of the research were to identify factors that influence e-business adoption and its impact on logistics processes in the Greek food industry. Drawing on existing research, a conceptual framework and propositions were developed and six in depth case studies were carried out. In the framework, three major categories of influencing factors were distinguished: intra-enterprise, sector and supply chain factors. Findings suggest that e-business adoption is more affected by supply chain and sector factors, rather than intra-enterprise factors. Regarding the impact of e-business on logistics process, it seems that it is affected by the frequency of its use and it is greater in processes occurring at the company-customer interface. Finally, e-business impact is more related to the dimensions of time and quality, rather than cost improvements.

Non-verbal signalling in digital discourse:the case of letter repetition

This study focuses on the interactional functions of non-standard spelling, in particular letter repetition, used in text-based computer-mediated communication as a means of non-verbal signalling. The aim of this paper is to assess the current state of non-verbal cue research in computer-mediated discourse and demonstrate the need for a more comprehensive and methodologically rigorous exploration of written non-verbal signalling. The study proposes a contextual and usage-centered view of written paralanguage. Through illustrative, close linguistic analyses the study proves that previous approaches to non-standard spelling based on their relation to the spoken word might not account for the complexities of this CMC cue, and in order to further our understanding of their interactional functions it is more fruitful to describe the role they play during the contextualisation of the verbal messages. The interactional sociolinguistic approach taken in the analysis demonstrates the range of interactional functions letter repetition can achieve, including contribution to the inscription of socio-emotional information into writing, to the evoking of auditory cues or to a display of informality through using a relaxed writing style.

Optimal design of the renewable energy map of Greece using weighted goal-programming and data envelopment analysis

Renewable energy forms have been widely used in the past decades highlighting a "green" shift in energy production. An actual reason behind this turn to renewable energy production is EU directives which set the Union's targets for energy production from renewable sources, greenhouse gas emissions and increase in energy efficiency. All member countries are obligated to apply harmonized legislation and practices and restructure their energy production networks in order to meet EU targets. Towards the fulfillment of 20-20-20 EU targets, in Greece a specific strategy which promotes the construction of large scale Renewable Energy Source plants is promoted. In this paper, we present an optimal design of the Greek renewable energy production network applying a 0-1 Weighted Goal Programming model, considering social, environmental and economic criteria. In the absence of a panel of experts Data Envelopment Analysis (DEA) approach is used in order to filter the best out of the possible network structures, seeking for the maximum technical efficiency. Super-Efficiency DEA model is also used in order to reduce the solutions and find the best out of all the possible. The results showed that in order to achieve maximum efficiency, the social and environmental criteria must be weighted more than the economic ones.

Using the e-Class Open Platform for e-Learning Support at the TEI of Larissa, Greece

In the current paper we firstly give a short introduction on e-learning platforms and review the case of the e-class open e-learning platform being used by the Greek tertiary education sector. Our analysis includes strategic selection issues and outcomes in general and operational and adoption issues in the case of the Technological Educational Institute (TEI) of Larissa, Greece. The methodology is being based on qualitative analysis of interviews with key actors using the platform, and statistical analysis of quantitative data related to adoption and usage in the relevant populations. The author has been a key actor in all stages and describes his insights as an early adopter, diffuser and innovative user. We try to explain the issues under consideration using existing past research outcomes and we also arrive to some conclusions and points for further research.

Improving distributed representation of word sense via WordNet Gloss composition and context clustering

In recent years, there has been an increas-ing interest in learning a distributed rep-resentation of word sense. Traditional context clustering based models usually require careful tuning of model parame-ters, and typically perform worse on infre-quent word senses. This paper presents a novel approach which addresses these lim-itations by first initializing the word sense embeddings through learning sentence-level embeddings from WordNet glosses using a convolutional neural networks. The initialized word sense embeddings are used by a context clustering based model to generate the distributed representations of word senses. Our learned represen-tations outperform the publicly available embeddings on 2 out of 4 metrics in the word similarity task, and 6 out of 13 sub tasks in the analogical reasoning task.

The Romanian Orthodox Church

At first glance, the nationalist ideology of the French Revolution seems to have had little impact on the Orthodox Church in Romanian-speaking territories. Romanians were the predominant inhabitants of the principalities of Wallachia and Moldavia and the neighboring territories of Transylvania (including Crişana, Maramureş and Banat), Bukovina, Bessarabia, and Dobrudja. The majority of ethnic Romanians belonged to the Orthodox faith while their communities were at the intersection of geopo liti cal interests of the Rus sian, Ottoman, and Habsburg empires. In 1859 the Principalities of Wallachia and Moldavia (known as the Old Kingdom between 1866 and 1918) united into a single state under the rule of a local prince. The term "Romania" began to be used by the new state in its of cial documents in 1862. Two years later, the state supported the declaration of a Romanian autocephalous (in de pen dent) church that was recognized by the Ecumenical Patriarchate in 1885. As an integrative part of the Orthodox commonwealth, the church was situated between the competing jurisdictions of the Ecumenical Patriarchate and the Rus sian Orthodox Church, while its declaration of autocephaly followed a pattern in the spread of national churches in Southeastern Europe. From the Treaty of Kuchuk Kainardji of 1774 to the beginning of the Greek War for In de pen dence in 1821, the Romanian principalities were under the suzerainty of the Ottoman Empire, which had full control of their po liti cal and economic affairs. The sultan appointed princes, and the Porte determined their po liti cal and judicial status. The princes were drawn from the "Phanariots," and were directly appointed by the Porte from preponderantly Greek elite rather than the Romanian local elite, the boyars (boieri).1 In each principality, the church was headed by a metropolitan who was under the direct jurisdiction of the Ecumenical Patriarchate. That religion mattered to local population as a means of social cohesion was suggestively depicted by Anatole de Demidoff, an En glish traveler in the region in 1837. Arriving in Bucharest, the capital of Wallachia, he claimed that: I know of no city in Europe in which it is possible to find more agreeable society, or in which there is a better tone, united with the most charming gaiety⋯. Religion, which is here of the schismatic Greek creed, does not, properly speaking, hold any great empire over the minds of the Wallachian people, but they observe its outward forms, and particularly the austerities of fasting, with scrupulous exactitude. The people are seen to attend divine ser vice with every sign of respect, and the great number of churches existing in Wallachia, bear witness to the ardent zeal with which outward worship is honored.2 The Romanian Orthodox Church was a national institution, closely linked to social, economic, and po liti cal structures. In most cases, Orthodox hierarchs were appointed from the families of boyars, thus ensuring a close relationship with the state authorities and its policies. As one of the largest landowners in the principalities, the church had a prime role in administrating healthcare and education. Although the majority of the clergy was uneducated, it dispensed both ecclesiastical and civil justice and in many cases worked closely with boyars in local administration.3 The lower clergy not only contributed directly to the economy but also benefited from tax privileges. Some small villages had an unusually high proportion of clergy in comparison to the overall population. For example, in 1810, Stənisləveşti, a village in the south of Wallachia, was composed of eleven houses and had two priests, five deacons, and three cantors; similarly, the Frəsinet village of nineteen houses had two priests and five deacons.4 Although these cases were exceptional, they indicate both the economic value of being a member of the clergy and the wider canonical dimension of church jurisdiction. The special status of the clergy was reflected not only at lower but also at higher levels. Bishops and metropolitans engaged with state policy and in many cases opposition to the authorities led to the loss of a spiritual seat. The metropolitan of each principality worked with the prince and was president of the divan, the gathering of all boyars. He held the right to be the first person to comment on state policy and to make recommendations when the prince was absent. The metropolitan replaced the prince when the principality had no political ruler, such as in the cases of Metropolitan Veniamin Costachi of Moldavia in 1806 and Metropolitan Dositei Filitti of Wallachia, while the bishops of Buzəu and Argeş were members of the provisional government during the Rus sian occupation of the principalities in 1808. The higher clergy had both religious and political prerogatives in relation to foreign powers as evident in their heading of the boyars' delegation to peace negotiation between the Rus sian and Ottoman empires at Focşani in 1772 and addressing memoranda to the Austrian and Rus sian governments in 1802.5 The primary role of the church in the principalities of Moldavia and Wallachia was paralleled by the national mobilization of Orthodox communities in the neighboring territories that had Romanian inhabitants. Although throughout the region Orthodox communities were incorporated into church structures as part of the Habsburg, Austrian or Rus sian empires, the nineteenth century was characterized by the leadership's search for political autonomy and the building of a Romanian national identity. The Orthodox communities outside the Old Kingdom maintained relations with the faithful in principalities across the Carpathian Mountains and the Dniester River and sought support in their struggle for political and religious rights.
