Evolution in size and structural order for incipient soot formed at flame temperatures greater than 2100 K
Authors: Camacho Joaquin , Dasappa Shruthi
Published: February 2021

Soot formed in flames hotter than conventional combustion applications is expected to undergo unique formation processes and develop a carbon structure distinct from typical soot. A complementary experimental and modeling approach is reported here to assess flame temperature and equivalence ratio effects for soot formed in the higher-temperature regime (1950 K < Tf < 2250 K). Computations using three separate combustion chemistry models show that predictions of polycyclic aromatic hydrocarbon (PAH) concentration profiles for the higher-temperature flames are more sensitive to the choice in mechanism rather than specific flame conditions. As for material properties, the Raman signatures transition from a typical soot spectrum to features observed in disordered sp2 carbon materials. The defect distance extracted from the Raman bands nearly doubles from values typically reported for soot as the flame temperature exceeds 2200 K. Higher concentrations of gas-phase precursors may facilitate development of an ordered carbon structure as indicated by the relatively high defect distance observed for the highest equivalence ratio series. Particle size distributions measured by mobility sizing show size and yield of soot decreases with increasing flame temperature and the bimodal distribution falls within the ultra-fine range for all flame conditions. This is especially promising if the significant transformation in carbon structure inferred from the evolution in Raman spectra enables development of functional high-surface area sp2 carbon materials. Namely, the current observations indicate that the flame-formed carbon structure evolves towards high-defect sp2 carbon with size and carbon structure that can be tuned to some extent.

Published: February 2021

Background: Non-invasive neurofeedback training is currently explored as a potential add-on therapy to treat patients suffering from major depressive disorder, and first trials show promising clin-ical effects. The temporal evolution of therapeutic change, however, remains unclear. Methods: Profile of mood states (POMS) questionnaire ratings were collected immediately before and after five sessions of real-time fMRI neurofeedback training (rt-fMRI-NFT) in a randomised controlled trial (RCT). Data were analysed for within and between treatment sessions ef-fects. Results: Trajectories of mood profiles varied between subscales. Total mood disturbance and the subscales depression and tension showed both within and between treatment sessions ef-fects, although within-session effects were descriptively larger. Limitations: The sample size was relatively small owed to the current state of the rt-fMRI-NFT field. No data from a sham-neurofeedback control group was available. Conclusions: The presented data provides a better understanding of when changes in mood states occur. The POMS questionnaire allows monitoring rapid and slowly evolving changes in mood states and can thus inform future study designs for neuromodulation and psychological in-terventions for mental disorders.

Published: February 2021

Appreciation and sense of coherence have been widely researched for their links to well-being. however, the relevance of the concept with regard to the current state of happiness adds a unique perspective. In the present study, we investigate the role of appreciation towards emotional well-being in the context of the current pandemic (COVID-19), and whether the sense of coherence mediates this relationship. Participants (N= 234) were presented with measures of appreciation, sense of coherence and well-being. Our results indicate that appreciation leads to emotional wellbeing and sense of coherence mediated this relationship. Furthermore, we found positive correlations between all the three variables. Overall, our findings contribute to the literature on positive functions served by appreciation, specifically towards emotional wellbeing. Additionally, this study points to the mediating mechanism through which appreciation exerts its positive effects by pointing out the role of sense of coherence in this link.

Published: February 2021

In the last few decades, the field of neuroscience has witnessed major technological advances that have allowed researchers to measure and control neural activity with great detail. Yet, behavioral experiments in humans remain an essential approach to investigate the mysteries of the mind. Their relatively modest technological and economic requisites make behavioral research an attractive and accessible experimental avenue for neuroscientists with very diverse backgrounds. However, like any experimental enterprise, it has its own inherent challenges that may pose practical hurdles, especially to less experienced behavioral researchers. Here, we aim at providing a practical guide for a steady walk through the workflow of a typical behavioral experiment with human subjects. This primer concerns the design of an experimental protocol, research ethics and subject care, as well as best practices for data collection, analysis, and sharing. The goal is to provide clear instructions for both beginners and experienced researchers from diverse backgrounds in planning behavioral experiments.
Hierarchies of Motivation Predict Individuals’ Attitudes and Values: A Neuropsychological Operationalization of the Five Factor Model
Authors: Berg Cameron
Published: February 2021

Scientific investigations of human personality are concerned with uncovering recurrent patterns of behavior, valuation, and cognition across time. The Five Factor Model (FFM), commonly known as the “Big 5,” is considered the most scientifically rigorous consolidation of the components of human decision-making and behavior. This research presents a novel hypothesis for systematizing the factors of the FFM into a series of emotional, motivational, and intellectual trade-offs. 193 adult participants completed an online decision-making battery composed of scenarios generated in accordance with each superordinate trade-off framework. Machine learning algorithms were subsequently implemented to assess whether a participant’s individual “score” was able to predict their independently-reported attitudes related to political affiliation, gender identity, career preferences, economic beliefs, political correctness, spirituality, and others. Across every attitude probed, the trade-off framework presented in this research was able to predict participant responses at levels statistically significant at p < .00001. This pilot investigation thus strongly supports the utility of conceptualizing individual decisions, preferences, values, and motivations through the lens of the FFM-based trade-off frameworks outlined in this work.

Published: February 2021

Objective: Adolescents with anorexia (AN) and bulimia nervosa (BN) often struggle with emotion regulation (ER). These difficulties have predominantly been assessed across emotions, without considering adaptive and maladaptive ER separately.We compared adolescents with AN or BN to healthy adolescents (HCs) regarding the adaptive and maladaptive ER of three emotions. Methods: A treatment-seeking sample of 197 adolescents (atypical/full-threshold AN: N = 118, atypical/full-threshold BN: N = 32; HC: N = 47) reported emotion-specific ER with the FEEL-KJ questionnaire. Mixed models were calculated for adaptive and maladaptive ER to assess differences between emotions (anxiety, anger, sadness) and groups (AN, BN, HC). Results: Main effects of emotion (p < .001) and group (p < .001) were found, but no interaction effects were found (p > .05). Post-hoc tests showed lower maladaptive and higher adaptive ER for anxiety than anger or sadness (p < .001). AN and BN reported lower adaptive (p < .001) and higher maladaptive ER than HCs (p < .001). BN showed the highest levels of maladaptive ER (p = .009). Discussion: The differences between AN and BN in adaptive and maladaptive ER should be considered. Furthermore, investigating differences in ER of other emotions in eating disorders might be promising.
Predicting compliance with COVID-19 containing measures using context-specific and dispositional individual differences: The particular role of individual’s sense of responsibility for collective health
Authors: Lachowicz-Tabaczek Kinga , Kozłowska Monika
Published: February 2021

In this research, we examined whether context-specific individual differences would allow for a better prediction of pandemic-related attitudes and behavior than non-specific dispositional traits. In Study 1, we introduced a context-specific measure of individual differences in the sense of responsibility for collective health (SRCH) and compared its ability to predict the acceptance of pandemic-related restrictions, with that of pandemic-related worries considered as a context-specific but self-oriented tendency and with two dispositional traits, i.e., grandiose and vulnerable narcissism. Only SRCH and pandemic-related worries uniquely predicted the acceptance of restrictions. In Study 2, we examined whether SRCH predicted increased hygiene and social distancing during pandemic better than narcissistic traits and pandemic worries, as well as social responsibility personal values—an others-oriented disposition. The results showed that SRCH explained most of the unique variance in social distancing, whereas pandemic-related worries uniquely predicted most of the variance in hygiene practices. Of the dispositional traits, only social responsibility personal values predicted a unique portion of the variance in social distancing, whereas narcissistic traits added no incremental value in predicting any of the precautionary measures. The results of both studies indicate that context-specific individual differences are robust predictors of compliance with COVID-19 mitigating measures.
Social Inequalities in Mobility During and Following the COVID-19 associated lockdown of the Madrid Metropolitan Area in Spain
Authors: Glodeanu Adrián , Bilal Usama , Tosio Pedro Gullón
Published: February 2021

Spain has been one of the most affected regions by the COVID-19 worldwide, and Madrid its most affected city. In response to this, the Spanish government enacted a strict lockdown in late March, that was gradually eased until June. We explored differentials in mobility by area-level deprivation in the functional area of Madrid, before, during, and after the COVID-19 lockdown. We used cell phone-derived mobility indicators (% of the population leaving their area) from the National Institute of Statistics (INE), and a composite measure of deprivation from the Spanish Society of Epidemiology (SEE). We computed changes in mobility with respect to pre-pandemic levels, and explored spatial patterns and associations with deprivation. We found that levels of mobility before COVID-19 were slightly higher in areas with lower deprivation. The economic hibernation period resulted in very strong declines in mobility, most acutely in low deprivation areas. These differences weakened during the re-opening, and levels of mobility were similar by deprivation once the lockdown was lifted. Given the existence of important socioeconomic differentials in COVID-19 exposure, it is key to ensure that these interventions do not widen existing social inequalities.
Is It Only a Numbers Game? A Macro-Level Study of Educational Hypogamy
Authors: Han Sinn Won
Published: February 2021

In many countries, the tendency for highly educated women to marry down in education has markedly increased. Existing research has pointed to an oversupply of highly educated women – i.e., the marriage squeeze against women – as the core reason for this phenomenon. This paper aims to provide a more comprehensive understanding of the causes of this marriage trend by analyzing over-time census data from 34 countries. Key findings are as follows. First, the degree of educational hypogamy is associated with the magnitude of the college man deficit in the marriage market, which is consistent with the marriage squeeze hypothesis. However, I find evidence that the impact of the mating squeeze significantly differs depending on the group size of college-educated women: the smaller this group (and thus more exclusive), the less they opt for marrying down even if they face a shortage of marriageable men. Second, the degree of educational hypogamy is related to the economic empowerment of college-educated women, even after netting out the mating squeeze effect. Third, counterfactual simulations show that while the mating squeeze is the major driver of educational hypogamy in the majority of the sample countries, the economic empowerment of college-educated women plays an equally important role in several countries.

Exploring Transformative Pedagogy in Teaching Mathematics
Authors: Shrestha Indra Mani , Luitel Bal Chandra , Pant Binod Prasad
Published: February 2021

This paper is based on the first author’s auto/ethnographic inquiry into pedagogical practices based on his MPhil dissertation. The second author being the dissertation supervisor has played a facilitative role in developing the structure and content of the paper while the third author has provided critical comments and inputs on overall aspects of the paper. Various research studies show that teaching mathematics has been a challenging task for many teachers in Nepal. Based on our experience, most of the mathematics teachers including the first author are found struggling for improving their pedagogical skills to provide students with meaningful (authentic, empowering, justifiable and inclusive) learning. In so doing, instead of looking into their ‘inner-selves”, they oftentimes wander around the outer world seeking the better (and the best) possible pedagogical approaches. In this orientation, as an auto/ethnographer, the first author narrates his stories on pedagogical practices to examine his traditional teacher-centric pedagogical practices and explore the transformative pedagogy as student-centric pedagogy. The study helped him improve his pedagogical practices and envision a synergy of teacher-centric pedagogy and transformative pedagogy in his professional life-world. Therefore, this paper aims at sharing the research context, theoretical position, methodology, and reflection and lessons learned. This paper is developed from the perspective of the first author’s experience using the first person “I”.
STEAM Pedagogy as an Approach for Teacher Professional Development
Authors: Pant Sanjaya Kumar , Luitel Bal Chandra , Pant Binod Prasad
Published: February 2021

The ongoing in-service teacher learning or formal teacher professional development (TPD) is too conventional and de-escalating as the disciplinary skills and knowledge of teacher is insufficient to solve real world problems which are multi-disciplinary in origin. Thus, there is a critical need to explore and introduce multidisciplinary pedagogy with wise integration of science, technology, engineering, arts and mathematics (STEAM) concepts as an approach for TPD. This paper aims to explore the possible approaches of introducing STEAM pedagogy as an approach for TPD. This argumentative paper is prepared with the help of relevant and useful literatures. We argue the urgent need to integrate arts and technology in subject disciplines and design STEAM projects and training module as a neo-approach for TPD. This approach is equally useful for pre-service as well as in-service school teachers to develop multidisciplinary ways of knowing and solving real world problems.

Oral biofilms harbour gram-negative bacterial antigen lipopolysaccharide (LPS) involved in oral cancer
progression and gram-positive bacterial surface-associated adhesive, lipoteichoic acid (LTA). Thus, we
hypothesised that LPS and LTA together would increase the proliferation of cancer cells compared to
stimulation by LPS alone. Oral cancer cell lines SCC4, SCC9, SCC25, Cal 27 and the normal oral cell line,
OKF6, were studied. The bacterial antigen stimulation indices were determined using the MT Glo assay.
Cell proliferation after bacterial antigen stimulation was validated by clonogenic assays. Phosphokinase
array, reverse transcription-quantitative polymerase chain reaction (RT-qPCR), and Western blot were
employed to study proliferative and apoptotic pathways in bacterial antigen-stimulated cells. Bacterial
antigens significantly stimulated Cal 27 (p ≤ 0.001) alone. SCC4 and SCC9 showed negligible stimulation
with either antigen, while SCC25 results were comparable to OKF6. The combined antigen stimulation of
Cal 27 led to a decrease in phosphorylated p53 and β-catenin and higher PI3K compared to LPS only
stimulated cells (p ≤ 0.001). Combined bacterial antigen stimulation results in increased proliferation of Cal
27 cells due to lowering of tumor suppressor proteins and increased tumor proliferation-related proteins.

Absensi fingerprint merupakan absensi yang memakai sidik jari manusia, dan sidik jari adalah identitas pribadi yang tidak mungkin ada yang menyamakannya. Sifat-sifat atau karakteristik yang dimiliki oleh sidik jari adalah parennial nature yaitu guratan-guratan pada sidik jari manusia yang melekat seumur hidup. Lazimnya absensi dipakai pada setiap kehadiran dalam bekerja sehari – hari. Absensi fingerprint merupakan alat penggerak pegawai untuk hadir tepat waktu dan pulang kerja sesuai dengan waktu yang telah ditetapkan.  Hal ini diharapkan agar para pegawai dapat meningkatkan kedisiplinan dalam bekerja. Metode yang digunakan dalam penelitian ini untuk mengetahui seberapa besar pengaruh absensi fingerprint terhadap peningkatan disiplin kerja pegawai yaitu dengan metode statistik SPSS versi 25. berupa Uji Koefisien Korelasi, Uji Koefisien Determinasi dan Uji Persamaan Regresi sehingga dapat diketahui tindakan dan pemecahannya. Berdasarkan olah data yang penulis lakukan hasil penelitian ini menunjukkan bahwa nilai Koefisiensi Korelasi sebesar 0,773 artinya absensi fingerprint yang diselenggarakan mempunyai hubungan yang positif dan kuat terhadap peningkatan disiplin kerja pegawai pada Kementerian Komunikasi dan Informatika Jakarta, sedangkan hasil Koefisien Determinasi berkontribusi sebesar 59,7% dan sisanya 40,3% dipengaruhi oleh faktor lain. Hasil Persamaan Regresi sebesar Y=-1,625+1,010 X artinya setiap variable mengalami penurunan 1 kali maka akan mengalami penurunan sebesar 1,010. Dengan demikian absensi fingerprint berpengaruh kuat terhadap peningkatan kedisiplinan kerja pegawai.
