Using dual-EEG to explore therapistclient interpersonal neural synchrony
Authors: Lecchi Tanya , da Silva Ksenija , Giommi Fabio , Leong Victoria
Published: December 2019

The therapeutic alliance represents an important variable in explaining the outcome of mental health treatment. In particular, research suggests that mindfulness practice might help therapists to develop skills that are key to a good therapeutic alliance. Although the therapeutic alliance is well-recognised from a clinical perspective, basic quantitative research is still lacking about the neurocognitive mechanisms involved in establishing and maintaining the alliance between individuals. Recent advances in two-person neuroscience research have demonstrated that interpersonal neural synchrony -which may develop between speaker and listener, or parent and child -is a strong predictor of mutual understanding as well as social learning and influence. Further, social cues that improve communication quality and clarify intent effectively modulate levels of interpersonal neural synchrony, suggesting that this neural index is sensitive to dynamic changes in speaker-listener engagement. Given that the therapeutic alliance depends strongly on shared intentionality and mutual engagement between therapist and client, interpersonal neural synchrony may also index the quality and strength of the therapist-client alliance, and predict treatment outcome. If so, this quantitative neural index could provide a useful clinical tool for measuring and understanding the nature and efficacy of the therapeutic alliance. The present paper discusses these hypotheses, presenting preliminary data from a pilot study investigating neural synchrony between clients and therapists in face-to-face and videoconference interactions, comparing therapists who practice mindfulness with therapists without any mindfulness experience.
Fighting National Amnesia: Profiling Public Attention to Mass Shootings in The United States
Authors: Chandler Miles
Published: December 2019

This study aims to identify factors that shape public perception and emotional response to mass shootings in the United States. I suggest that patterns of media coverage inform public consciousness and collective emotion. Newsworthiness and gatekeeping theories assert that school or prejudicial shootings and those with more victims are reported on at higher rates. Literature on racial and immigrant bias in media demonstrates that non-white shooters also generate more discourse. The directed construction of shootings and the affective public responses they generate align well with the concept of a “moral panic.” Using all valid cases from the Mother Jones Mass Shootings:1982-2019 dataset which align temporally with Google Trends data, I analyze the volume and decay rate of search topics “mass shooting,” “gun control,” and “open carry,” following US mass shootings from 2004-2019. Shootings with more victims predict a higher volume of searches for “mass shooting,” and shorter search periods for “gun control” and “open carry.” Shootings with educational and religious targets had no significant effects on search patterns. Workplace shootings result in longer search periods for “mass shooting,” and shorter periods for “gun control.” Non-white shooters generate shorter search decay for “open carry.” The results support theories of media gatekeeping, suggesting events with more casualties generate more intense public attention. The consistent negative correlation between search volume and decay length suggests that sensational responses to shootings are not sustainable over long periods of time and prohibit pragmatically addressing mass shootings.
Understanding stakeholders in malnutrition from system thinking perspective for better policy and planning: A review
Authors: Jain Rahi , Narnaware Prashant
Published: December 2019

Malnutrition is an important issue in developing countries like India. India’s focus on malnutrition has been since its first five-year plan but the challenge persists. Several studies have identified causes behind the malnutrition, but efforts are made to address those causes, but results are inadequate. This review focuses on understanding the malnutrition from the systems perspective. The paper critically examines the literature to identify the various stakeholders that influence the malnutrition scenario of an area. The focus is on understanding the relevance of having systems thinking approach in dealing with the malnutrition issue. The paper concludes that significant understanding has been built around individual causes and stakeholders’ role in malnutrition. However, the need exists to translate this understanding into strategies that are relevant for the implementers on the ground who have to address the malnutrition issue in context-specific multi-stakeholder interests and demands.
A Weighted Balance Model of Opinion Hyperpolarization
Authors: Schweighofer Simon , Schweitzer Frank , Garcia David
Published: December 2019

Polarization is threatening the stability of democratic societies. Until now, polarization research has mainly focused on opinion extremeness, disregarding the correlation between different policy issues. We explain the emergence of hyperpolarization, i.e., the combination of extremeness and correlation between issues, by developing Weighted Balance Theory (WBT), a new theory of opinion formation. WBT extends Heider's cognitive balance theory to encompass multiple weighted attitudes. We validate WBT on empirical data from the 2016 National Election Survey. Furthermore, we develop an opinion dynamics model based on WBT, which, for the first time, is able to generate hyperpolarization and to explain the link between affective and opinion polarization. In addition, our theory encompasses other phenomena of opinion dynamics, including mono-polarization and backfire effects.

This paper focuses on the analysis of translation strategies of slang language as employed in the movie entitled “The Social Network”. This paper analyzes the translation strategies of the slang language from English into Indonesia from the movie entitled “The Social Network”. Baker’s translation strategies were used in this paper in order to analyze the data of this paper.  The study findings reveal that there are 30 slang words used in this movie, and the subtitler adopted five translation strategies by Baker for translating the slang words in this movie. The analysis also reveals that most of the slang words in the movie have related words with the target language. There are no English slang words that were translated into Indonesia slang words in the movie. The subtitler mostly used the strategies for translating the English slang words into Indonesian words that have a similar expressive meaning. It can be interpreted as a result of the different culture of both countries that makes different slang words.

Authors: Sulistianingsih Endang , Febriani Rizka , Pradjarto Jcs
Published: December 2019

Vocabulary Achievement is an element of learning the language which may assist students in understanding the language through basic English skills. Interactive Board Games are board games that use multimedia system (PowerPoint) teaching technique. This is often one of the traditional games that may be played by group activity and paired with a blackboard to focus on visual media activity. To find out the effect of using Interactive Board Games on students’ vocabulary achievement, we used the quantitative approach by assigning experimental research. There were two groups that we used in this research. Group one as experimental group and other as a control group. We used Total Pscycal Response (TPR) method for both groups, but we often gave Interactive Board Games to the experimental group in the learning process. There were eight meetings that we conducted into the experimental group with treatment using Interactive Board Games. We calculated the data from the test given when students learning English used Interactive Board Games. Before the test gave to the sample, the writer gave the test to students who have the same ability but not sample to know regarding validity and reliable of the test. Based on the t-test, we found that the t-ratio was higher than the t-table. The result indicated that there was a significant difference between the students who were taught using Interactive Board Games and the students who were not taught using Interactive Board Games.

Authors: Okoi P. O. , Edet C.O. , Magu T. O.
Published: December 2019

We present the relativistic treatment of the Hellmann-generalized Morse potential using Nikiforov-Uvarov(NU) method. The relativistic equations(Klein-Gordon and Dirac equation) were solved using the conventional NU method. In order to overcome the centrifugal barrier, we employed the  well-known Greene and Aldrich approximation scheme. The corresponding normalized eigenfunctions was also obtained in each case. It was shown that in the non-relativistic limits, both energy equations obtained by solving Klein-Gordon and Dirac equations, and wavefunctions reduced to the non-relativisitc energy Equation. The bound state energy eigenvalues for N2, CO, NO, CH and HCl diatomic molecules were computed for various vibrational and rotational quantum numbers. It was found that our results agree with those in literature.

Published: December 2019

The purpose of this study is to develop a method of calculating the vibration partition function of diatomic molecules for the Morse potential energy. After a brief introduction about the eigensolutions obtained for the problem in question, Via the Euler-Maclaurin formula, we have determined the thermal properties for four diatomics such as \text{H}_{2}, HCl, LiH, and CO. Different situation has been exposed and explained by the appropriate curves of the thermal properties for these diatomics molecules in consideration. In addition, we have shown that our method exposed to calculate these thermal properties can be used to determine these thermodynamic quantities.
Complementary atomic force microscopy and magnetic force microscopy study for the magnetic transition of cobalt clusters onto gold substrates
Authors: Rivera M. , Martinez-Vado F. I. , Mendoza-Huizar L. H. , Betancourt I.
Published: December 2019

Atomic and magnetic force microscopy were employed in order to investigate the local magnetic state of individual cobalt clusters electrodeposited onto gold electrodes. The analysis indicated that the diameter of the clusters was similar regardless of the potential formation, or growth stage, but the height and surface coverage changed as the potential augmented. Individual examination of the clusters showed that the height determined the magnetic transition from the single to the multi domain state. By using a theoretical single-domain ferromagnetic model in terms of the clusters dimensions, the magnetic exchange constant at different potential voltages was obtained, which was higher than the cobalt bulk value. In addition, a micromagnetic simulation study was employed to validate the experimental results, and it correctly confirmed the experimental magnetic transition. In addition, a fcc crystalline structure and some insights of the clusters growth mechanism on the gold surface were inferred from the results.

The Mn2SnSe4 compound was synthesized by the melt and annealing technique and its structure was refined by the Rietveld method using X-ray powder diffraction data. This compound crystallizes in the olivine-type structure with unit cell parameters a = 12.9028(2) Å, b = 7.9001(1) Å, c = 6.5015(1) Å, V = 662.72(2) Å3 in the orthorhombic space group Pnma (Nº 62). This olivine structure can be described from a hexagonal close-packing of selenium atoms where manganese atoms occupy ½ of the octahedral sites while thin atoms lay in ⅛ of the tetrahedra.
A theoretical study of variation of photoionization cross section of donor impurities in a GaAs quantum dot of cylindrical geometry with incident photon frequency, donor location along the dot axis and applied uniaxial stress
Authors: Oketch F. , Oyoko H.
Published: December 2019

In this work, we have used a variational technique within the effective mass approximation to study the variation of the photoionization cross section of a donor impurity in a cylindrical GaAs quantum dot with incident photon frequencies and applied uniaxial stress. We have used the dipole approximation and assumed that the barrier potential is infinite. Our results show that the photoionization cross section begins at a finite value and increases with increasing frequency until it reaches a peak and then it decreases gradually, almost exponentially, until it reaches a finite value when it is almost insensitive to any further increase in frequency. Furthermore, for a particular quantum dot length, the photoionization cross section decreases with increasing applied uniaxial stress. We have also noted that the longer the quantum well dot the larger is the photoionization cross section

Published: December 2019

A preliminary study of the magnetic relaxation in (Bi, Pb)-2223 superconducting ceramics doped with α-Al2O3 nanoparticles is presented, taking as starting point the measurements of the M(t) dependence, both in samples in the form of powder as in pellet. The relaxation of the three types of vortices that can exist inside these materials is analyzed, emphasizing on the intragranular regionwhere the planar defects exist and, consequently, Abrikosov-Josephson vortices emerge. Finally, interesting results of the comparison between the behavior of the samples in the form of powder and in the form of pellet are shown from the estimation of the pinning energy of the vortices.

Published: December 2019

A comparative study between the addition of Co3O4 micro-particles and nano-particles as densifying dopant of a SnO2 based varistor system was conducted. The ceramic composition was (99.9-X) %SnO2–X %Co3O4–0.05 %Cr2O3–0.05 %Nb2O5 where X = 0, 0.5, 1.0, 2.0 and 4.0 mol%. Two particle sizes of Co3O4 were used (~5 µm and ~50 nm). The addition of 0.5 mol% of Co3O4 nano-particles promoted an increase of grain size of sintered samples up to 7.9 µm, that is, the maximum value among all variations.  Characterization techniques such as TGA, DTA, XRD, and Rietveld analysis revealed a decrease of 16 ºC in the formation temperature of Co2SnO4 as well as an increase of 2.6 wt% in the amount of said phase with the use of 4.0 mol% of Co3O4 nano-particles in comparison with micro-particles. Statistical analysis indicated that the addition of nano-particles of Co3O4 yield better repeatability on densification of ceramic samples. Residual porosity also was decreased. Electrical breakdown and non-linear coefficient values correspond to a non-ohmic behavior with potential application on manufacture of high voltage varistors. The findings of this work can be used as a reference for conducting a later study to improve the electrical properties or even to lower the sintering temperature.
Modelado computacional Reynolds-Averaged Navier-Stokes flamelets para el estudio del proceso de combusti´on turbulenta de sprays
Authors: Guevara-Morales G. , Huerta-Chávez O. , Arias-Montaño A.
Published: December 2019

En el presente trabajo es aplicada una técnica numérica 2D acoplada de Dinámica de Fluidos Computacional (CFD) para reproducir, estudiar y analizar los proceso de combustión turbulenta de sprays. El método utilizado es el Promediado de los Esfuerzos de Reynolds de las Ecuaciones de Navier-Stokes (RANS) acoplado al modelo de combustión de flamas en contraflujo (flamelets) a través de una función de densidad probabilística (PDF) definida por el usuario. La correcta simulación del proceso de combustión está basada en el modelo experimental desarrollado por el NIST y los resultados experimentales reportados por Widmann y Presser [1]. Los resultados obtenidos de la simulación son comparados con los resultados experimentales de velocidad a 9.5 y 17.6 mm del inyector en la dirección axial. Estos resultados muestran correspondencias cerradas con los datos experimentales de los perfiles de velocidades radial, axial y tangencial a lo ancho de la cámara de combustión en el intervalo de 14 a 50mm. Además de la velocidad del flujo también se compara la distribución, tamaño y velocidad de las gotas de combustible, así como la composición de los gases de escape en relación a los NOx que se producen. De acuerdo a los resultados la diferencia en la distribución de gotas sobre el ángulo de dispersión del spray afecta al resto de características del spray. La diferencia en el diámetro promedio de Sauter sugiere que posiblemente la velocidad de evaporación de las gotas de mayor tamaño es sobreestimado. Finalmente se confirma que, dada la suposición sobre la velocidad de reacción rápida, el modelo de combustión predice que la combustión es prácticamente completa, aunque se tengan gotas cuya evaporación se logra más allá de la zona de reacción.

Hemodynamic analysis of the recipient parasylvian cortical arteries for predicting postoperative hyperperfusion during STA-MCA bypass in adult patients with moyamoya disease
Authors: Zhang Jianjian , Li Sirui , Fujimura Miki , Lau Tsz Yeung , Wu Xiaolin , Hu Miao , Zheng Hanpei , Xu Haibo , Zhao Wenyuan , Li Xiang , Chen Jincao
Published: December 2019

OBJECTIVE

Superficial temporal artery–middle cerebral artery (STA-MCA) bypass is a common approach for treating moyamoya disease (MMD); however, the selection of recipient vessels is still controversial, and its relationship with postoperative cerebral hyperperfusion (CHP) has not been revealed. The aim of the study was to investigate the relationship between the hemodynamic sources of the recipient parasylvian cortical arteries (PSCAs) and the occurrence of postoperative CHP.

METHODS

The authors retrospectively analyzed the clinical data from 68 adult patients (75 hemispheres) with MMD who underwent STA-MCA bypass. Based on their hemodynamic sources from the MCA and non-MCAs, the PSCAs were classified as M-PSCAs and non–M-PSCAs, and their distributional characteristics were studied. Moreover, the patients’ demographics, incidence of postoperative CHP, and post- and preoperative relative cerebral blood flow values were examined.

RESULTS

The digital subtraction angiography analysis demonstrated that 40% (30/75) of the recipient PSCAs had no hemodynamic relationship with the MCA. The post- and preoperative relative cerebral blood flow values of the M-PSCA group were significantly higher than those of the non–M-PSCA group (p < 0.001). Multivariate analysis revealed that the hemodynamic source of PSCAs from the MCA was significantly associated with the development of focal (p = 0.003) and symptomatic (p = 0.021) CHP. Twelve (85.7%) of the 14 patients with symptomatic CHP and all 4 (100%) patients with postoperative hemorrhage were from the M-PSCA group.

CONCLUSIONS

This study revealed that direct anastomoses of PSCAs with anterograde hemodynamic sources from the MCA had a high risk of postoperative CHP during STA-MCA bypass in adult patients with MMD.
Deep brain stimulation versus pallidotomy for status dystonicus: a single-center case series
Authors: Levi Vincenzo , Zorzi Giovanna , Messina Giuseppe , Romito Luigi , Tramacere Irene , Dones Ivano , Nardocci Nardo , Franzini Angelo
Published: December 2019

OBJECTIVE

First-line pharmacological therapies have shown limited efficacy in status dystonicus (SD), while surgery is increasingly reported as remediable in refractory cases. In this context, there is no evidence regarding which neurosurgical approach is the safest and most effective. The aim of this study was to assess the clinical outcomes and surgery-related complications of globus pallidus internus deep brain stimulation (GPi DBS) and pallidotomy for the treatment of drug-resistant SD.

METHODS

The authors reviewed the records of patients with drug-resistant SD who had undergone GPi DBS or pallidotomy at their institution between 2003 and 2017. The severity of the dystonia was evaluated using the Barry-Albright Dystonia (BAD) Scale. Surgical procedures were performed bilaterally in all cases.

RESULTS

Fourteen patients were eligible for inclusion in the study. After surgery, the mean follow-up was 40.6 ± 30 months. DBS ended the dystonic storm in 87.5% of cases (7/8), while pallidotomy had a success rate of 83.3% (5/6). No significant differences were observed between the two techniques in terms of failure rates (risk difference DBS vs pallidotomy −0.03, 95% CI −0.36 to 0.30), SD mean resolution time (DBS 34.8 ± 19 days, pallidotomy 21.8 ± 20.2 days, p > 0.05), or BAD scores at each postoperative follow-up (p > 0.05). The long-term hardware complication rate after DBS was 37.5%, whereas no surgery-related complications were noted following pallidotomy.

CONCLUSIONS

The study data suggest that DBS and pallidotomy are equally safe and effective therapies for drug-resistant SD. The choice between the two techniques should be tailored on a case-by-case basis, depending on factors such as the etiology and evolution pattern of the underlying dystonia and the clinical conditions at the moment of SD onset. Given the limitation of the low statistical power of this study, further multicentric investigations are needed to confirm its findings.
Correlation of spontaneous and traumatic anterior skull base CSF leak flow rates with fluid pattern on early, delayed, and subtraction volumetric extended echo train T2-weighted MRI

Published: December 2019

OBJECTIVE

CSF leakage is a potentially fatal condition that may result when a skull base dural defect permits CSF communication between the cranial vault and sinonasal cavities. Flow rate is an important property of CSF leaks that can contribute to surgical decision-making and predispose patients to complications and inferior outcomes. Noninvasive preoperative prediction of the leak rate is challenging with traditional diagnostic tools. The present study compares fluid configurations on early and late volumetric extended echo train T2-weighted MRI by using image tracings and sequence subtraction as a novel method of quantifying CSF flow rate, and it correlates radiological results with intraoperative findings and clinical outcomes.

METHODS

A total of 45 patients met inclusion criteria for this study and underwent 3-T MRI. Imaging sequences included two identical CUBE T2 (vendor trade name for volumetric extended echo train T2) acquisitions at the beginning and end of the scanning session, approximately 45 minutes apart. Twenty-five patients were confirmed to have definitive spontaneous or traumatic anterior skull base CSF leaks. Semiautomated volumetric segmentation of CSF intensity was performed on both CUBE data sets by using 3D-Slicer software, and volumes were subtracted to obtain accumulated CSF volume. These imaging-derived fluid accumulations were correlated with high- or low-flow states, as well as ultimate treatment outcomes including recurrences.

RESULTS

Of the 45 patients, 25 (55.6%) had definitive evidence of CSF leakage, and 22 (88%) of these underwent surgical repair. Patients with high-flow CSF leaks had higher early (4.058 cm3 vs 0.982 cm3, p = 0.04), late (4.58 cm3 vs 1.096 cm3, p = 0.04), and accumulated (0.53 cm3 vs 0.11 cm3, p = 0.01) fluid volume measurements than patients with low-flow leaks. The 5 (22.7%) patients who exhibited postoperative CSF leak recurrence had significantly greater early (6.30 cm3 vs 1.23 cm3, p = 0.008) and late (6.87 cm3 vs 1.45 cm3, p = 0.008) volumes. Accumulated volume was not significantly greater in patients with leak recurrence (0.58 cm3 vs 0.22 cm3, p = 0.07). Early, late, and accumulated volumes were significantly correlated with postoperative hospital stay as well as duration of postoperative lumbar drain placement (p < 0.05 for all measures).

CONCLUSIONS

High-resolution CUBE T2 MRI, coupled with precise volumetric segmentation and subtraction of sinonasal hyperintensity, not only demonstrated predictive value in differentiating low- and high-flow CSF leaks, but also correlated with postoperative complications such as leak recurrence. These findings may be useful in the clinical workup and neurosurgical management of patients with skull base CSF leaks.

Published: December 2019

OBJECTIVE

The ventral intermediate nucleus (VIM) of the thalamus is currently the established target in the use of deep brain stimulation (DBS) to treat essential tremor (ET). In recent years, the caudal zona incerta (cZi), a brain target commonly used during the lesional era, has been revived as the primary target in a number of DBS studies that show evidence of the efficacy of cZi targeting in DBS treatment for controlling the symptoms of ET. The authors sought to obtain comprehensive neuropsychological data and thoroughly investigate the cognitive effects of cZi targeting in patients with ET treated with DBS.

METHODS

Twenty-six consecutive patients with ET who received DBS with cZi as the target at our department from December 2012 to February 2017 were included in this study. All patients were assessed using a comprehensive neuropsychological test battery covering the major cognitive domains both preoperatively and 12 months postoperatively.

RESULTS

The results show no major adverse effects on patient performance on the tests of cognitive function other than a slight decline of semantic verbal fluency.

CONCLUSIONS

This study indicates that the cZi is a safe target from a cognitive perspective in the treatment of ET with DBS.

Background: COPD is a pulmonary disease characterized by air obstruction in respiratory tract from bronchi to the bronchioles, which continuously occur progressively, and irreversible, and related with the inflammatory response due to toxic gases (cigarette smoke, factory pollution and vehicle pollution) so it can cause a desaturation oxygen (SpO2). This impact will caused in concentration decreased, functional activity reduction, hypoxemia, hypoxia until cyanosis. To prevent this impact, there are two non-pharmacological methods that can be applied, a tripod position and pursed lips breathing exercise. Purpose: To determine the effectiveness of tripod position and pursed lips breathing to enhance oxygen saturation in patients with COPD.Methods: The research used queasy experimental with pre-posttest design. This research used total sampling that have 34 samples COPD patient which is include in inclusion criteria in working area of Puskesmas Padangsari Semarang. The samples are divided into 2 treatment groups (tripod position groups and pursed lips breathing groups) that gives 15 minutes therapy 3 times within 3 continuous days. This research will begins from February until March 2019. Statistical test to determine the affectivity of each groups using non-parametric test (Mann-Whitney test). Results: the result of this research shows differences effectiveness between tripod position and pursed lips breathing with p value 0.00 with mean deviation before and after therapy of tripod position 0.29 and pursed lips breathing 1.23.Conclusion: in this research shows that pursed lips breathing is most effective to enhance oxygen saturation in COPD patient compare with tripod position.

Published: December 2019

Cognitive Internet of Things (CIoT) is the next leap towards enhancing the accuracy and effectiveness of Internet of Things (IoT) technology used in combination with cognitive computing that has a significant role in healthcare and diseases diagnosis. The work in this paper proposes a system to diagnose the sensitivity toward sound and light by developing a mechanism based on facial emotions recognition system that integrate with IoT protocols and cloud computing. The proposed system was achieved by establishing a cognitive IoT environment composed of hardware and software components that practically implemented in a laboratory to identify the behavior of people suffering from sensitivity toward sound and light. This behavior was observed by monitoring human face emotions through a live video capturing using camera and image processing using facial emotion recognition software. Emotions values obtained was examined and collected in a cloud using (MQTT) protocol. These emotions were classified as normal and abnormal. Normal state give the impression that the surrounding environment is appropriate for people senses and they do not suffer from any discomfort, therefore the system works on a mechanism to increase the intensities of sound or light in this environment and vice versa.

Eco, Golding’s Rites of Passage and Breaching the Limits of Being
Authors: KORBUT SALMAN Volha
Published: December 2019

William Golding’s novel Rites of
Passage (1980) explores the depths of human experience, absorbed in and
struggling against the cognitive, ontological and referential limits inherent
in its essence. By portraying Edmund Talbot and James Colley on an
equator-crossing voyage to Australia, Golding emphasizes the fact that it is
darkness that lies beyond the lines that systemize and limit human existence,
which is manifested by Colley’s death. In this way, Rites of Passage comports with Umberto Eco’s theory of ‘contractual
realism’, elaborated in Kant and the
Platypus: Essays on Language and Cognition (1999), in a sense that it
asserts that within a framework of a cultural contract, there are certain
things that we as human beings are vetoed from doing in our inquiry after the
essence of Being. This article provides a thematic examination of William
Golding’s novel Rites of Passage in
the light of Umberto Eco’s theory of ‘contractual realism’.
