Silicate-Carbonate Liquid Immiscibility: Insights from the Crevier Alkaline Intrusion (Quebec)

This contribution explores the petrogenetic relationships between silicate and carbonatitic rocks in the Crevier Alkaline Intrusion (CAI, Quebec, Canada). The CAI is located in the Proterozoic Grenville Province and is composed of a suite of undersaturated peralkaline rocks from ijolite to nepheline syenite and carbonatites. Petrogenetic relationships between different undersaturated alkaline igneous rocks, carbonate-bearing and carbonate-free nepheline syenite and carbonatites observed in the CAI suggest that (i) carbonate-bearing and carbonate-free silicate rocks are comagmatic with carbonatite, and that (ii) both silicate and carbonatitic liquids are fractionated from an ijolitic parental magma that has undergone liquid immiscibility. One of the observed facies is characterized by spectacular ocelli of carbonate-bearing nepheline syenite in a matrix of carbonatite. The younger nepheline syenite facies can be divided into two groups based on the presence or absence of magmatic carbonates. Both groups are characterized by the presence of pyrochlore-group minerals that carry the Nb-Ta mineralization. We specifically use accessory minerals such as zircon, pyrochlore and apatite to constrain the temporal and physicochemical parameters of the immiscibility process. By coupling (i) mineral textures, (ii) trace elements, (iii) Ti-in-zircon thermometry, and (iv) oxygen isotope compositions, we have traced the crystallization of zircon before, during and after the immiscibility process. The results allowed us to constrain the minimum temperature of this process at ∼815-865 °C. In addition, two magmatic populations of pyrochlore are identified through their petrographic and geochemical characteristics within the younger nepheline syenite facies. Pyrochlore from the earlier ocelli facies of carbonate-bearing nepheline syenite follow a Nb-Ta differentiation trend, whereas pyrochlore from the younger carbonate-free nepheline syenite follow a more classical Nb-Ti trend. Following the complete immiscibility between the silicate and carbonatitic liquids, the fractionation between Nb and Ta stopped while a new generation of Nb-rich pyrochlore grew, displaying a more classical Nb-Ti fractionation trend and a more constant Nb/Ta ratio in the nepheline syenite.
The Mediating Effect of Empathy on the Relationship between Cultural Intelligence and Intercultural Adaptation in Intercultural Service Encounters

Globalization has led to a dramatic increase in intercultural service encounters between services providers and customers from diverse cultural backgrounds. This paper explores the causal relationship between service employees‟ cultural intelligence and adaptive sales behavior in intercultural service encounters, and the mediating effect of cognitive and emotional empathy on this relationship. A quantitative survey methodology was utilized to collect data on 341 salespeople at duty-free shops located on Jeju Island, Korea. Data analysis was conducted using SPSS 18 and Amos 18. The results show that cultural intelligence has a significant impact on cognitive empathy, emotional empathy, and adaptive sales behavior. Cognitive empathy has a positive impact on adaptive sales behavior, whereas the relationship between emotional empathy and adaptive sales behavior is not significant. Additionally, cognitive empathy mediates the relationship of cultural intelligence and adaptive sales behavior. This study has useful managerial implications for employee selection, training, and development in service firms engaged in intercultural service encounters. This study extends prior research on intercultural service encounters by exploring the direct impact of cultural intelligence on intercultural adaptation and the mediating effect of empathy, suggesting the presence of a cognitive mechanism that plays a key role in the impact of cultural intelligence on adaptive sales behavior.
Deep Learning for Environment Identification in Vehicular Networks

This letter proposes a deep learning approach for identifying the ambient environment of smart vehicles. Without deploying any dedicated sensors, we exploit the available wireless channel measurements at the wireless receivers of smart vehicles to identify the surrounding environment so that smart vehicles can behave accordingly. We treat the environment identification problem as a multi-class classification problem and employ a deep convolutional neural network (DCNN) to tackle it. The past observations of the estimated channel state information are used as the input features to train the DCNN. Then, the trained DCNN is deployed on vehicles to perform environment identifications. Our numerical results show that the proposed DCNN approach accurately identifies the surrounding environment and achieves the best classification performance compared to other rival machine learning approaches.
An investigation of the relationship between anterior knee pain and lower limb biomechanics.

The thesis presents an investigation of the relationship between anterior knee pain and lower limb biomechanics in symptomatic and asymptomatic individuals during walking. Although foot orthotic devices are often prescribed to realign lower extremity mechanics, there is conflicting evidence to support this. A quantitative study explored the dynamics of walking barefoot, shod and with orthotic devices using the 3D Kinematic Motion Analysis System, Vicon 370. Sample sizes of 30 control subjects and 30 subjects with anterior knee pain were recruited. Kinematic gait parameters and temporal-spatial gait parameters were compared between the two groups and a thorough static clinical examination was provided. The relationship of alignment and knee pain was also examined using the Positional Upright MRI Scanner. A group of 15 subjects with anterior knee pain and a group of 5 asymptomatic subjects were examined radiographically barefoot, shod and with orthotic devices. An increase in Q-angle was shown in the knee pain group with an added angle increase in the females in both groups. This could signify that a higher Q-angle may influence biomechanics of the knee joint by creating an abnormally increased valgus angle. Evidence was found that there was a strong relationship between eversion and inversion of the foot with internal and external tibial rotation of the leg. This coupling relationship may lend insight into the behavior of the lower leg and anterior knee pain whilst walking. Small changes were noted when wearing the orthotic devices which may be advantageous biomechanically and they were also of benefit in correcting pronatory changes or movements more distal to the foot. The results of the MRI study were disappointing but many limitations were shown to support the results. Upon finishing this thesis, it is apparent that documented evidence of any relationship between anterior knee pain and lower limb biomechanics is imperative to clinicians in order to aid in treatment plans of patients but also in preventative treatment. Further research is required to enhance the clinicians knowledge and understanding of the foot and leg dynamically.
A Rapid Evidence Assessment of the correlates of Criminal Social Identity (CSI)

The Integrated Psychosocial Model of Criminal Social Identity (IPM-CSI) explains the underlying reasons, i.e. risk factors, for the development of criminal social identity (CSI). Empirical research surrounding these risk factors is inconsistent in the measures and procedures used and the risk factors were mostly considered in isolation from one another. The main purpose of the paper was to review existing empirical studies elucidating correlates of CSI incorporated in the IPM-CSI and indicate further direction for research. A search in PubMed, PsychInfo, ERIC, Google Scholar, and the journal Child Development and Adolescent Studies was performed. Eleven studies exploring the correlates of CSI were identified and discussed herein. Studies indicated that there is potential for further expansion of the IPM-CSI to consider the consequences of CSI. Based on the present study results, a set of recommendations are provided for future research.
Beyond cost–benefit analysis: resident emotions, appraisals and support toward tourism performing arts developments

ABSTRACT Abundant literature has examined resident reactions to tourism by their perceptions of perceived impacts, overlooking individual emotional responses that might be elicited by psychological causes toward specific types of tourism. This paper employs cognitive appraisal theory to explore the existence and causes of resident emotional responses to tourism performing arts developments. A survey of 438 residents was conducted in Hangzhou, China. Findings revealed that love and interest were dominant emotions. Appraisals of pleasantness, goal congruence, goal relevance, fairness, certainty and coping potential positively elicited happiness, love and gratefulness yet were negatively related to sadness and anger. Worry was elicited by low coping potential and high certainty of outcomes while anger was positively related to other attributions for tourism impacts. Results also detected that resident positive emotions had much more effects than negative emotions on their supports to TPA. The findings have implications for the way destinations position and promote tourism developments to encourage community engagement and manage resident hostility.
‘Whitelash?’ status threat, anger, and white America: a general strain theory approach

ABSTRACT Progress towards racial equality has left many Whites, particularly men, feeling that Whites have replaced Blacks as the principal victims of discrimination. Thus, although Whites’ privileged position in American society disallows their true oppression, many still feel discriminated against. Following a general strain theory framework, this study examines the associations between perceived anti-white bias, anger, and offending for White youth. Furthermore, we investigate if the revealed associations vary by gender. Results suggest that Whites who perceive experiencing high levels of anti-white bias have high levels of offending behaviors. Moreover, these associations are amplified by anger and felt the strongest by young men. These findings underscore the importance of incorporating critical perspectives on whiteness into the study of crime.
The Effect of Vacuum Quenching on Corrosion and Hardness of the Surface of SKD61 Steel

JIS SKD61 Steel is chromium-molybdenum hot work steel which has composition 5.58 wt% Cr – 2.51 wt% Mo. This steel is a well-known material used as a die material to get good mechanical and hardening properties. Besides this material should have good corrosion resistance. Samples made of SKD61 steel were subjected to vacuum heat treatment at 1030°C for 3 hours with step quenching in different rates of quenching. The difference in the cooling speed of each sample causes properties on the surface to vary. Micro Hardness Vickers is a tool used to determine micro-scale hardness. While to test corrosion resistance, electrochemical testing was carried out using NaCl solution with variations in concentrations of 1%, 3.5%, and 7%. X-Ray Diffraction was used to characterize the crystal structure and the crystallite size. The results show that the speed of quenching affects the hardness of the surface of the material, structure and corrosion resistance.
Survey Of Data Mining Techniques Used In Healthcare Domain And Diagnosis Of Dengue Fever

: Healthcare organisations and industries produces huge amount of data everyday. These vast information can be extracted and analysed to obtain patterns which can be used to forcast or predict the future events. Many healthcare organizations have already started collecting healthcare records to systematically use those data to identify patterns and improve health management of a particular population thereby providing improved care and reduced manual work and cost. This paper focuses on the survey of different dengue fever classification and study of a particular population where people are mostly diagnosed with dengue infection. It also discusses critical issues and challenges associated with data mining and healthcare in general. The research found a growing number of data mining applications, including analysis of health care centres for better health policy-making, detection of disease outbreaks. We have collected data from government hospitals. We have applied these data in our fuzzy logic and generated decision tree and compared the performance of other techniques.
MONITORING THE DIELECTRIC PROPERTIES AND PROPAGATION CONDITIONS OF MORTAR FOR MODERN WIRELESS MOBILE NETWORKS

Recently, modern wireless communication applications are extended to call high frequency bands including millimeter waves for 5G systems. Therefore, the propagation properties of such waves in different media have attracted many researchers. In this work, the results of the Sparameters measurements of mortar with four thicknesses are obtained using a nondestructive free space measurement technique for the frequency bands from 8 GHz up to 32 GHz. The obtained results of the dielectric properties and loss factors for the prepared mortar samples are realized. The variation in both the reflection and transmission coefficients and the dielectric properties with curing time conditions of mortar structure is examined. The dielectric properties of water are realized using the proposed method to subtract the effects of water contents from the prepared mortar samples. The effects of the sample thickness and relaxation frequency are considered. The obtained measurements are compared to the simulated results based on a full wave simulation software package of CSTMWS algorithms. Finally, excellent agreements are achieved between the simulated and measured results.
Analyses of rare collection samples as conservation tool for the last known Italian population of Graphoderus bilineatus (Insecta: Coleoptera)

Abstract Graphoderus bilineatus is a predacious diving beetle, widely distributed across Europe. Its poor dispersal ability and the fragmentation and deterioration of its habitats have been indicated as the major causes of decline. In several western European countries, the species is extinct, justifying its inclusion as “vulnerable” in the IUCN red list. Aiming for the conservation of the last known population of G. bilineatus in the northern Italian region of Emilia Romagna, at the lake Pratignano, we surveyed its genetic diversity at the mitochondrial COI gene and compared it to that of other European populations. Two fixed COI haplotypes were found in the Italian and Austrian populations, respectively. Both haplotypes were unique among the European populations surveyed, suggesting these populations suffered a bottleneck and geographic isolation. Populations in western Europe showed lower genetic diversity and higher degree of differentiation than eastern populations. The uniqueness of Pratignano haplotype makes it difficult to choose a source population from which to transfer animals for a possible restocking. Selection of the source population should be based mainly on ecological considerations, but at the same time ensuring a good genetic diversity to maximize the adaptive potential.
Forest-Fire Recognition by Sparse and Collaborative Subspace Clustering

Traditional forest-fire recognition based on the characteristics of smoke, temperature and light fails to accurately detect and respond to early fires. By analyzing the characteristics of flame, the methods based on aerial image recognition have been widely used, such as RGB-based and HIS-based methods. However, these methods are susceptible to background factors causing interference and false detection. To alleviate these problems, we investigate two subspace clustering methods based on sparse and collaborative representation, respectively, to detect and locate forest fires. Firstly, subspace clustering segments flame from the whole image. Afterwards, sparse or collaborative representation is employed to represent most of the flame information in a dictionary with l1-regularization or l2-regularization term, which results in fewer reconstruction errors. Experimental results show that the proposed SSC and CSC substantially outperform the state-of-the art methods.
The Rasch Model as a Loglinear Model

The Rasch model is formulated as a loglinear model. The goodness of fit and parameter estimates of the Rasch model can be obtained using the itera tive proportional fitting algorithm for loglinear models. It is shown in an example that the relation between the estimates of the iterative proportional fitting algorithm and the unconditional maximum likelihood Rasch algorithm are almost perfectly lin ear. The Rasch model can be extended with a de sign for the items, which can be formulated as a loglinear model.
Convergence and divergence in anti-predator displays: A novel approach to quantitative behavioural comparison in snakes

Animals in nature use diverse strategies to evade or deter their predators, including many vivid behavioural displays only qualitatively described from field encounters with natural predators or humans. Within venomous snake mimicry, stereotyped anti-predator displays are suggested to be a critical component of the warning signal given by toxic models and thus under strong selection for independent convergence in mimetic species. However, no studies have systematically quantified variation in snake anti-predator displays across taxonomically broad clades to test how these behaviours evolve across species within a phylogenetic comparative methods framework. Here we describe a new, high-throughput approach for collecting and scoring snake anti-predator displays in the field that demonstrates both low observer bias and infinite extension across any species. Then, we show our method’s utility in quantitatively comparing the behaviour of 20 highly-divergent snake species from the Amazonian lowlands of Peru. We found that a simple experimental setup varying simulated predator cues was very successful in eliciting anti-predator displays across species and that high-speed videography captured a greater diversity of behavioural responses than described in the literature. We also found that although different display components evolve at different rates with complicated patterns of covariance, there is clear evidence of evolutionary convergence in anti-predator displays among distantly related elapid coral snakes and their colubrid mimics. We conclude that our approach provides new opportunity for analyses of snake behaviour, kinematics, and the evolution of anti-predator signals more generally, especially macroevolutionary analyses across clades with similarly intractable behavioural diversity.
Current Practices for Teaching Letter and Letter Sound Knowledge in Preschool Including Strategies for Improving Instruction in these Areas

Head Start teachers (N= 48) were interviewed about their beliefs and practices for supporting letter knowledge in their classrooms. Results highlighted that teachers believed letter knowledge to be important skill for preschoolers to develop and articulated a variety of approaches to supporting this skill within their classrooms. Promoting letter knowledge through play and childrenâ€™s name letters were popular approaches; however, teachers missed many opportunities to promote letter and letter-sound knowledge with their children. Thus, in addition to presenting findings from semi-structured interviews, this article provides a range of research-based practices available to promote letter and letter-sound knowledge during preschool.
Technology and Social Media Usage in Higher Education: The Influence of Individual Innovativeness

This article presents a two-phase study exploring the usage of technology in higher education as well as the role of the general innovativeness in predicting the actual use of technology. During the first phase of the study, which involved 502 staff members, a descriptive analysis of their usage of social media, technological devices, and Microsoft Office 365 cloud services was performed, with various demographic variables being considered. During the second phase, which involved a subsample of 106 staff members, structural equation modeling (SEM) was used to examine a model in which the general innovativeness and the demographic variables acted as predictors of the actualized innovativeness. The results showed that the staff used social media, devices, and cloud services quite satisfactorily. The examination of their user profiles revealed that there were significant differences among the staff members on the basis of their demographic variables, especially their gender, job type, and discipline. The results of the SEM showed that the general innovativeness contributed positively, as was expected, to predicting the adoption of devices, non-academic social networking sites and Office 365 cloud services. The results further suggested that males were early adopters of devices, while academics were early adopters of commercial services and academic social networking sites. However, the academics appeared to lag behind the administrators in terms of adopting Office 365 cloud services. The implications of the study and directions for future research are also presented.

In addition, these problems may bring on negative effects on the occupational and social lives of the patients[3, 4]. Many studies have demonstrated that physical disorders may lead to social phobia, and this could negatively affect a person’s life[5]. Social and economic rehabilitation of the amputated patients is an important issue. Literature reviews have indicated that there have been very few studies evaluating the psychological parameters of amputated patients[6]. However, to our knowledge, no study has been conducted reporting the social phobia, depression and quality of life in patients with major lower limb amputation and comparing them with a control group. In this study, we investigated the social phobia, depression and quality of life in patients with major lower limb amputation in comparison to the control group. In addition, we analyzed the subgroups concerning age, gender, cause of amputation, and time since amputation. Our hypothesis is that in patients with major lower-extremity amputation, social phobia and depression will be a more serious and poorer quality of life when compared to the control group. Materials and Methods Patients who were amputated above or below the knee in the past and applied to our clinic between January 2010 and December 2013 were evaluated retrospectively in this study after approval of the local ethics committee. An informed consent was obtained from each participant. Patients older than 18 years of age who completed at least one year after amputation were included in this study. Patients who were diagnosed with psychiatric illness and/or who used the psychiatric drug during or before this study were excluded from this study. The control group was randomly selected among the persons who visited the inpatients at the hospital.
