Rietveld Quantitative Stability of Portland Blast Furnace Slag Cement Between Internal and External Standard Methods
Authors: Zhao P. , Liu X. , Lu L. , Wang P. 
Published: October 2017

Abstract
The internal and external standard (G-factor) methods were applied to Rietveld/XRD quantitative analysis of Portland blast furnace slag cement using X’Pert Highscore Plus and GSAS-EXPGUI software. The Rietveld quantitative result derived from G-factor calculation and application was compared by internal standard methodology, which was employed by separately adding 20 and 50 % (weight percentage) of SiO2. The results show that the quantitations obtained by both of the above independent methods are almost consistent. In addition, the quantitative difference of most crystalline phases are less than 1 % except C4AF, about 1.2 %, while the amorphous determination has the quantitative difference of 2.1 %. Beside the careful sample preparation, proper XRD pattern collection, and satisfactory Rietveld refined procedure, the polished quartz rock used for mean G-factor calculation and the modified formula for amorphous calculation contributed to the Rietveld quantitative stability and reasonability. The formula based on amorphous quantification by internal standard was expressed as WAmor = 1−(WS(1−WS(PS+Sta)′))/((WS(PS+Sta)′−WS(PS)′)(1−WS)).
Physiological Information for Pavement Ride Quality Verification
Authors: Tomiyama K. , Kawamura A. 
Published: October 2017

Abstract
Heart rate variability (HRV) refers to the beat-to-beat fluctuations in heart rate, which is one of the most promising physiological indicators reflecting mental stress of humans. It has different spectral components in the high and low frequency ranges that are 0.15–0.4 Hz and 0.04–0.15 Hz, respectively. One of the interesting features of HRV is that mental stress inactivates the high frequency (HF) spectral oscillations depending on its severity. The purpose of this study was to verify pavement ride quality ratings based on HRV. For this purpose, a sophisticated driving simulator (KITDS: Kitami Institute of Driving Simulator) was employed and was confirmed to be applicable to physiological testing for pavement ride quality. The result of the simulator experiment showed that the HF oscillations in the time-frequency plane analyzed by continuous wavelet transform decreased with the increase of surface roughness in terms of the international roughness index (IRI). This phenomenon was validated by the on-site experiment using an actual vehicle prior to the ride quality verification study using the KITDS. In the verification study, we observed a particular case of which the subjective ratings were inconsistent with physiological stress signs in terms of the HF oscillations. Although the traditional questionnaire-based testing allows direct measurement of the ride quality of road users, in such a case, the participants of the experiment are unconsciously exposed to mental stress regarding ride quality. The experiment result indicated that 70 % of the participants suffered the unconscious mental stress. To improve this inconsistency, we categorized subjective ratings into three categories depending on the HF oscillations of HRV. According to the result, we suggested that the IRI of 3 mm/m was reasonable as a threshold of pavement ride quality acceptance at the highway speed of 80 km/h.
Dynamic Trial-by-Trial Recoding of Task-Set Representations in the Frontoparietal Cortex Mediates Behavioral Flexibility

Published: October 2017

Cognitive flexibility forms the core of the extraordinary ability of humans to adapt, but the precise neural mechanisms underlying our ability to nimbly shift between task sets remain poorly understood. Recent functional magnetic resonance imaging (fMRI) studies employing multivoxel pattern analysis (MVPA) have shown that a currently relevant task set can be decoded from activity patterns in the frontoparietal cortex, but whether these regions support the dynamic transformation of task sets from trial to trial is not clear. Here, we combined a cued task-switching protocol with human (both sexes) fMRI, and harnessed representational similarity analysis (RSA) to facilitate a novel assessment of trial-by-trial changes in neural task-set representations. We first used MVPA to define task-sensitive frontoparietal and visual regions and found that neural task-set representations on switch trials are less stably encoded than on repeat trials. We then exploited RSA to show that the neural representational pattern dissimilarity across consecutive trials is greater for switch trials than for repeat trials, and that the degree of this pattern dissimilarity predicts behavior. Moreover, the overall neural pattern of representational dissimilarities followed from the assumption that repeating sets, compared with switching sets, results in stronger neural task representations. Finally, when moving from cue to target phase within a trial, pattern dissimilarities tracked the transformation from previous-trial task representations to the currently relevant set. These results provide neural evidence for the longstanding assumptions of an effortful task-set reconfiguration process hampered by task-set inertia, and they demonstrate that frontoparietal and stimulus processing regions support “dynamic adaptive coding,” flexibly representing changing task sets in a trial-by-trial fashion.SIGNIFICANCE STATEMENTHumans can fluently switch between different tasks, reflecting an ability to dynamically configure “task sets,” rule representations that link stimuli to appropriate responses. Recent studies show that neural signals in frontal and parietal brain regions can tell us which of two tasks a person is currently performing. However, it is not known whether these regions are also involved in dynamically reconfiguring task-set representations when switching between tasks. Here we measured human brain activity during task switching and tracked the similarity of neural task-set representations from trial to trial. We show that frontal and parietal brain regions flexibly recode changing task sets in a trial-by-trial fashion, and that task-set similarity over consecutive trials predicts behavior.
Neural Signature of Value-Based Sensorimotor Prioritization in Humans
Authors: Blangero Annabelle , Kelly Simon P. 
Published: October 2017

In situations in which impending sensory events demand fast action choices, we must be ready to prioritize higher-value courses of action to avoid missed opportunities. When such a situation first presents itself, stimulus–action contingencies and their relative value must be encoded to establish a value-biased state of preparation for an impending sensorimotor decision. Here, we sought to identify neurophysiological signatures of such processes in the human brain (both female and male). We devised a task requiring fast action choices based on the discrimination of a simple visual cue in which the differently valued sensory alternatives were presented 750–800 ms before as peripheral “targets” that specified the stimulus–action mapping for the upcoming decision. In response to the targets, we identified a discrete, transient, spatially selective signal in the event-related potential (ERP), which scaled with relative value and strongly predicted the degree of behavioral bias in the upcoming decision both across and within subjects. This signal is not compatible with any hitherto known ERP signature of spatial selection and also bears novel distinctions with respect to characterizations of value-sensitive, spatially selective activity found in sensorimotor areas of nonhuman primates. Specifically, a series of follow-up experiments revealed that the signal was reliably invoked regardless of response laterality, response modality, sensory feature, and reward valence. It was absent, however, when the response deadline was relaxed and the strategic need for biasing removed. Therefore, more than passively representing value or salience, the signal appears to play a versatile and active role in adaptive sensorimotor prioritization.SIGNIFICANCE STATEMENTIn many situations such as fast-moving sports, we must be ready to act fast in response to sensory events and, in our preparation, prioritize courses of action that lead to greater rewards. Although behavioral effects of value biases in sensorimotor decision making have been widely studied, little is known about the neural processes that set these biases in place beforehand. Here, we report the discovery of a transient, spatially selective neural signal in humans that encodes the relative value of competing decision alternatives and strongly predicts behavioral value biases in decisions made ∼500 ms later. Follow-up manipulations of value differential, reward valence, response modality, sensory features, and time constraints establish that the signal reflects an active, feature- and effector-general preparatory mechanism for value-based prioritization.

In the postnatal forebrain regionalized neural stem cells along the ventricular walls produce olfactory bulb (OB) interneurons with varying neurotransmitter phenotypes and positions. To understand the molecular basis of this region-specific variability we analyzed gene expression in the postnatal dorsal and lateral lineages in mice of both sexes from stem cells to neurons. We show that both lineages maintain transcription factor signatures of their embryonic site of origin, the pallium and subpallium. However, additional factors, including Zic1 and Zic2, are postnatally expressed in the dorsal stem cell compartment and maintained in the lineage that generates calretinin-positive GABAergic neurons for the OB. Functionally, we show that Zic1 and Zic2 induce the generation of calretinin-positive neurons while suppressing dopaminergic fate in the postnatal dorsal lineage. We investigated the evolutionary conservation of the dopaminergic repressor function of Zic proteins and show that it is already present inC. elegans.SIGNIFICANCE STATEMENTThe vertebrate brain generates thousands of different neuron types. In this work we investigate the molecular mechanisms underlying this variability. Using a genomics approach we identify the transcription factor signatures of defined neural stem cells and neuron populations. Based thereon we show that two related transcription factors, Zic1 and Zic2, are essential to control the balance between two defined neuron types in the postnatal brain. We show that this mechanism is conserved in evolutionary very distant species.

Abstract

Objectives
For occupational health (OH) nurses to perform activities effectively, not only skills and knowledge but also competencies proposed by Dr. McClelland are indispensable. This study aimed to identify competencies required for OH nurses and to show their structure diagram.

Methods
Qualitative descriptive research was conducted from October 2010 to August 2011. Eight high-performing OH nurses participated, and data were collected from semi-structured interviews held for each nurse. Data were qualitatively and inductively analyzed using the KJ method.

Results
Seven competencies were identified: “self-growth competency,” “OH nursing essence perpetuation competency,” “strategic planning and duty fulfillment competency,” “coordination competency,” “client growth support competency,” “team empowerment competency,” and “creative competency.” A structure diagram of the seven competencies was clarified. As the definitions of the competencies were different, the findings of competencies for OH nursing in the United States of America (USA) could not simply be compared with the findings of our study; however, all seven competencies were compatible with those in AAOHN model 1 and AAOHN model 2 in the USA.

Conclusion
Our seven competencies are essential for OH nurses to perform activities that meet the expectations of employees and the employer.

Cambios en la mecánica ventilatoria debidos a variaciones de la PEEP y la presión soporte: estudio en sujetos sanos bajo ventilación mecánica no invasiva
Authors: Muñoz Isabel Cristina , Hernández Alher Mauricio 
Published: October 2017

Introducción. Por lo general, la mecánica ventilatoria se ha estimado en modo controlado con el uso de aproximaciones no adecuadas para ventilación espontánea.Objetivo. Medir los cambios de la mecánica ventilatoria ante variaciones de la presión positiva al final de la expiración (PEEP, por su sigla en inglés) y la presión soporte (PS) en ventilación mecánica no invasiva.Materiales y métodos. A través de una estrategia no invasiva, se estimó la mecánica ventilatoria bajo diferentes niveles de PEEP y PS. Para tal fin, se utilizó un simulador mecánico y se registró una base de datos de 14 sujetos sanos conectados de manera no invasiva a un ventilador mecánico.Resultados. Se obtuvieron valores medianos de resistencia y compliancia de 91.2[77.8-135.9]mL/cmH2O y 8.3[6.1-10.4]cmH2O/L/s para los 14 sujetos sanos con PEEP y PS de 0 cmH2O, respectivamente. En los incrementos de PEEP, los sujetos presentaron aumento estadísticamente significativo en la compliancia. Por el contrario, en el incremento de presión soporte, no se observaron cambios de ningún parámetro.Conclusiones. Se encontraron valores de compliancia y resistencia, acordes con los configurados en el simulador mecánico y coherentes con los reportados en la literatura en el caso de sujetos sanos. Esto resulta de gran utilidad al tomar decisiones en unidades de cuidados intensivos.

OBJECTIVE: This study aimed to determine the sex in human craniums using methodologies of Physical Anthropology, quantitative (Forensic Data Anthropology Bank, FDB, 1986) and one qualitative (Walker, 2008) and genetic analysis by amelogenin.METHODS: The sample was composed of 66 skulls (34 males and 32 females) from the Center for Study and Research in Forensic Science, Guarulhos, SP. The methodologies were applied by two researchers who were unaware of the cranium’s sexes. For the statistical analysis, there were performed descriptive analysis, average, standard deviation, linear discriminant analysis and logistic regression.RESULTS: The qualitative methodology presented an accuracy of 89.52%. For the DNA, it was possible to determine the sex in 86.15% of the sample. Analyzing the results for each skull in three different methodologies, we reached 100% correct.CONCLUSION: As a result of this study, it is recommended that physical anthropology be the chosen method if it presents good accuracy when applied to different populations or if it is validated for the analyzed population. Otherwise, genetic analysis should be used for the determination of the sex.
Micorriza arbuscular, Mucoromycotina y hongos septados oscuros en helechos y licófitas con distribución en México: una revisión global

Published: October 2017

Ferns and lycophytes are a group of vascular plants of interest to understand the evolution of mycorrhizal interactions; their preservation is of relevance for their multiple ecological relations. The record of different taxonomic groups of fungi associated with ferns and lycophytes is fragmentary, and the criteria for it identification is inconsistent, which hinders the understanding and determination of mycorrhizal status. The aim of this study was to determine the percentage of the species of ferns and lycophytes with distribution in Mexico, and with information of fungal interactions. A checklist of the presence of arbuscular mycorrhizal fungi (AMF), Mucoromycotina and dark septate fungi (DSF) associated with ferns and lycophytes was integrated through an exhaustive global literature search. In this study, mycorrhizal species was considered by the presence of arbuscules to differentiate with hyphal, vesicular and coils colonization. The study gathered a checklist of mycorrhizal occurrences of 27 families, 61 genus and 137 species of ferns and lycophytes, which covers 13.4 % of the species, 91 % of the genus and 77 % of the families distributed in Mexico. The 78.1 % of the species showed colonization, 56.2 % by AMF, 29.9 % by DSF and 0.72 % by Mucoromycotina fungi. From the total of the species, the higher presences of colonization were in terrestrial, epiphytic, saxicolous, and aquatic plants with 76.6 %, 33.3 %, 20 %, and 6.3 %, respectively. The families of ferns and lycophytes with the higher number of species colonized were Pteridaceae, Polypodiaceae, Aspleniaceae and Dryopteridaceae. The present study showed the widespread associations of AMF and DSF in ferns and lycophytes of Mexico. It is urgently needed to include ferns and lycophytes in studies focused on endomycorhizal interactions, since only 28 species (28 %) were studied in Mexican ecosystems. The majority of studies were focused on sporophytic face (80 %). Nonetheless, to understand the role that plays the mycorrhiza in the establishment of ferns and lycophytes, it is necessary to include the gametophytic face in ecological, molecular and physiological experimental studies. This information is important to implement conservation strategies, because a considerable number of ferns and lycophytes species, depend on these mycorrhizal associations for their growth and survival.
Centra i peryferie jako rama analityczna i pojęciowa
Authors: Kwarcińska Katarzyna 
Published: October 2017

The aim of the article is to investigate the centre – periphery framework for its practical usefulness as an analytical and explanatory tool to study the processes of space, cultural (including symbolic), political, and economic concentration and polarisation.There are two parts. The first examines theoretical problems concerning the application of the centre and periphery. The issues discussed include the fact that these concepts can be arbitrary, while there are many tacit additional assumptions surrounding the concepts of centre and periphery, which seem to make up a universal conceptual framework. The second part investigates the possibility of making a clear typology of centres and peripheries based the dominant processes and observable phenomena that make up the processes (examples are given for some of them). The article is a kind of metatheoretical overview and aims to identify further directions of centres-periphery research.As a result of the analysis, a list of observable categories comprising the description of centres and peripheries was made. These categories can be the foundation of a typologisation and operationalisation in empirical research. The concept of „periphery compensation” is of particular significance. It confirms the status of peripheries and reveals the direction of a dominant relation.
Baudelaire, un detective ? – le 1848 vu par Kiyoshi Kasai
Authors: Oshima Yui 
Published: October 2017

Kiyoshi Kasai (1948-), écrivain en première ligne au Japon, a un visage double : comme phénoménologue apprécié par son œuvre intitulé La Phénoménologie du terrorisme, il a complètement analysé et critiqué le radicalisme japonais du 1968 ; comme romancier populaire avac des séries de roman policier, il a engendré un détective-exradicaliste du 1968, Kakeru Yabuki. En 1968, il y a eu une révolution ratée au Japon. Le jeune Kasai était un des révoltants et la réalité lui a révélé que l’idée de liberté humaine partagée par les révoltants finissait par la violence affreuse. Cette expérience amère est toujours au centre de ses pensées.
Parmi ses œuvres nombreuses, on peut trouver un roman policier intitulé Le Diable dans la foule. Cette oœuvre est un peu particulière parce que c’est aussi un roman historique qui raconte la révolution française de 1848. Et ce qui est plus remarquable pour nous, c’est que le héros est un jeune homme qui s’appelle Charles B. Dufays.
Fébrier en 1848, Charles, un jeune poète inconnu assiste à la scène où un homme tire sur un journaliste. Ce coup de fusil non seulement coûte la vie au journaliste, mais aussi engendre un mitraillage et un massacre des révoltants. Pourquoi et qui a assassiné le journaliste ? Qu’est-ce que ça signifie, son dernier mot « jumelle » ? Pour trouver des réponses de ces énigmes, Charles frappe sur la porte du chevalier Auguste Dupain.
Il est sans doute naturel que Kasai, qui connait très bien les splendeurs et les misères, la fureur et l’échec de la révolution japonaise de 1968, s’intéresse à la révolution française de 1848 en tant que l’origine de l’époque contemporaine et à Baudelaire avec des regards fraternels. Car c’est bien lui qui a écrit dans Mon cœur mis à nu : « Ce qu’est l’empreur Napoléon III. Ce qu’il vaut. Trouver l’explication de sa nature, et sa providentialité » : cette attitude de trouver la providentialité, c’est exactement ce que Kasai veut garder pour le radicalisme de 1968 pour toute sa vie. Le romancier a mis, nous semble-t-il, dans ce livre grandiose tout son hommage à Poe, toute son interprétation de la poésie baudelairienne, toute sa réflexion sur les foules modernes au terme de Benjamin, tout son analyse phénoménologique de la révolution française de 1848 et tout son souvenir de la révolution échouée. Nous se proposons donc, dans cet exposé, de contribuer à une meilleure compréhension de l’idée que Kiyoshi Kasai a donné à son Baudelaire.
