Decision-Making Processes of Residents in Preservation, Thermal Comfort, and Energy Efficiency in Heritage Buildings: A Pilot Study in Mexico City

With building construction representing one of the largest sectors responsible for the use of natural resources, retrofitting existing heritage buildings becomes a necessity, albeit a challenging one. The emergence of specific guidance on retrofitting heritage buildings has unveiled more than never the need to understand how residents negotiate, thermal comfort, energy efficiency, and heritage conservation decisions. The paper reports the complexity of the decision-making process of residents of heritage buildings in the Historic Centre of Mexico City regarding energy efficiency, intending to improve thermal comfort and reduce energy consumption while preserving heritage values. The study involved in-depth semi-structured interviews with users of heritage buildings that were thematically analysed, complemented by the monitoring of internal environmental conditions and system dynamics analysis. The results show that although the residents perceived the buildings’ temperature as poor, passive thermal comfort actions (e.g., wearing more clothes and closing windows) were preferred against invasive retrofitting solutions for thermal comfort due to residents’ resistance to a potential loss in the buildings’ values and the high cost of changes. The degree of change necessary for maintenance, renovation, and actions for improving the thermal comfort of a heritage building is related to values and to their preservation for future generations. The users’ changes were limited to small-scale interventions in floors and ceilings while avoiding touching what they consider essential to preserve and protect (i.e., social and cultural values). Integrating the user into the decision-making process would enhance the long-term continuity and sustainability of retrofitting policies and guidelines, thus avoiding losing heritage-built stock.
MULTI-USER RELAYING SYSTEMS FOR ENHANCED PERFORMANCE AND SECRECY

OF THE DISSERTATION Multi-user relaying systems for Enhanced Performance and Secrecy by Yupeng Liu Dissertation Director: Athina P. Petropulu High data rate, reliability and secrecy are fundamental pursuits in wireless communications systems. A multi-user wireless environment is particularly challenging because of interference and potential information wiretap. This dissertation proposes to utilize relay techniques to achieve high data rate, high reliability and absolute secrecy in multi-user wireless communications systems. First, a communication system with multiple source-destination pairs needing to communicate simultaneously is investigated. A relay beamforming scheme is proposed, in which a multi-antenna relay assists the communication. The proposed scheme enjoys spatial multiplexing gain and has a significant data rate advantage over widely studied orthogonal transmission schemes, e.g., Time Division Multiple Access (TDMA) and Code Division Multiple Access (CDMA). The relay beamforming scheme also overcomes the difficulties of recently introduced interference alignment approaches by not requiring full cross-node Channel State Information (CSI). Beamforming schemes that maximize the system throughput and meet user Quality of Service (QoS) requirements are investigated, and both
How Does the COVID-19 Pandemic Affect People’s Willingness to Pay for Health in the Short and Long Term? A Longitudinal Study during and after the COVID-19 Pandemic in China

The COVID-19 pandemic has posed a substantial threat to people’s lives and aroused health concerns. This study aims at exploring the following questions. First, how does the COVID-19 pandemic affect people’s willingness to pay for health (WPH) in the short and long term? Second, what is the psychological mechanism underlying such an effect? Finally, what are the boundary conditions for this effect? To answer these questions, we conducted three longitudinal surveys. The first survey was launched in February 2020—the time of the most serious outbreak of COVID-19 in China. Data were obtained from 1548 participants through questionnaires on an online survey platform. The sample covered 297 prefecture-level cities in 31 provincial administrative regions. Subsequently, we conducted two follow-up surveys in August 2020 and July 2021. The samples of these surveys were randomly selected from the sample of the first survey. The findings showed that the pandemic promoted people’s WPH in the outbreak period. The fear of death and self-esteem mediated and moderated this effect, respectively. Moreover, the effect persisted for six months after the COVID-19 pandemic had been brought under control (August 2020). However, the effect disappeared after a year and a half (July 2021). These results indicate that the COVID-19 pandemic promoted people’s WPH and that this effect was sustained in the short term after the pandemic had been brought under control but not in the long term.
Evidence of Antioxidant Activity of Novel L-Glutaminase Purified from L. Gasseri BRLHM

*Corresponding Author: Butheina A. Hasson 100235@uotechnology.edu. iq Abstract Probiotic strains have the potential to be used as bio-preservatives and functional radical scavenging treatments in the future. Antioxidant tests, including DPPH radical scavenging, were used to evaluate the antioxidant effects of extracellular LGlutaminase isolated from L. gasseri BRLHM. Parameters for the promoted production of the enzyme under minimal production media were optimized. The importance of this study lies in enhancing the production of the LGlutaminase isolated from L. gasseri BRLHM with a high activity using these L. gasseri bacterial as antioxidant activity. In ion-exchange chromatography, the specific activity was 14.7U/mg protein, with 58.8% yield and 4.6 purification folds. In the gel filtration, the specific activity was 23.4 U/mg protein, with a yield of 54 % and 4.6 purification folds. According to the findings, L-Glutaminase isolated from L . gasseri BRLHM exhibited good antioxidant properties. As the concentration rose, there was a remarkable proportionate increase in scavenging activity. The IC50 values for control and LGlutaminase were 36.09 1.12 and 619.8 gm/ml, respectively. The IC50 values were discovered to be 100 and 200 μg/ml, respectively. Conclusion: For the first time, the high of LGlutaminase isolated L. gasseri BRLHM was shown to exhibit antioxidant. This could be a promising discovery for future radical scavenging treatments and antioxidant prophylaxis with natural probiotics.
Cumulative effects of sex pheromone components in mate recognition of Muscidifurax raptorellus

In insects, chemical information is often crucial for mate recognition. The chemical signal may be perceived already from a distance or only at close range, depending on the volatility of the sex pheromone compounds. In many species, close‐range mate recognition is mediated by compounds of low volatility that originate from the insects’ cuticular lipid layer. The most prominent constituents are usually non‐polar hydrocarbons, but other, more polar compounds can be present as well. Upon detection, these lipids can elicit courtship behaviour. We studied mate recognition in the parasitoid wasp Muscidifurax raptorellus Kogan & Legner (Hymenoptera: Pteromalidae). In this species, courtship behaviour starts with bouts of wing fanning (high frequency wing beats while standing or walking). Once the male has mounted the female, he shows stereotypical antennal movements (antennal courtship) that lead to female receptivity signalling and copulation. We investigated the role of chemical compounds for mate recognition by evaluating the reaction of male M. raptorellus towards live conspecifics and dummies treated with whole‐body extracts or with extract fractions (non‐polar, intermediately polar, and polar compounds) in bioassays. Our results indicate that despite the sex specificity of cuticular hydrocarbon profiles, these compounds alone are not sufficient for mate recognition. Rather, we found that cuticular lipids of all three fractions seem to constitute the mate recognition signal, with a ternary mixture eliciting wing fanning significantly more often than single fractions. Overall, our results suggest that the three lipid fractions contribute cumulatively to the mate recognition signal.
Toward a Comparative Approach to Language Acquisition

The world’s languages vary in almost every conceivable way, yet children readily learn their native language. Understanding how children can acquire such a diversity of different languages has been a long-standing goal for psychological science, yet current acquisition research is dominated by studies of children learning one particular language: English. In this article, we argue that progress toward this goal will require systematic comparisons between different languages. We propose three levels of comparison: coarse-grained comparisons contrasting unrelated languages to confirm or refute broad theoretical claims, fine-grained comparisons between closely related languages to investigate the impact of specific factors on acquisition outcomes, and within-language comparisons targeting the impact of socio-communicative differences on learning. This three-pronged comparative approach to language acquisition promises to provide new insights into the mechanisms and processes by which children acquire their native tongue under such varied linguistic and socio-communicative conditions.
Unpacking Mathematics Identity: Exploring Undergraduate Students’ Enduring Experiences

Changes in mathematics identity over time were examined as well as beliefs regarding the nature of mathematics identity and experiences with mathematics that might be related to mathematics identity development. Survey data from 131 college students were analyzed using a Wilcoxon Signed-Rank test to assess longitudinal changes in self-perceptions about mathematics identity. In addition, open-ended responses were analyzed using a phenomenological approach to examine experiences with and beliefs about mathematics. The results indicate that mathematics identity, as reported by students, is a stable measure over time. Several overarching themes emerged from the qualitative data to indicate that participants’ reported formative experiences center around to performing in mathematics and teaching others or sharing mathematics. A majority of participants believe it is possible to become a “math person”; however, an underlying belief that mathematics is an innate ability is also evident.
Low-rank tensor approximations for compositional distributional semantics

This thesis explores compositional distributional semantics: methods for mapping words to feature vectors representing their meaning, and composing these word vectors to produce representations of the meanings of longer expressions such as phrases and sentences. Several compositional distributional semantic methods use matrices and their generalization, higher-order tensors, to model multi-way interactions between vectors. Unfortunately, the size of these higher-order tensors has been one obstacle to large-scale implementations of the compositional frameworks that would be able to produce representations for full-length sentences with a diverse vocabulary. In this work, we investigate whether we can match the performance of full matrices and tensors with low-rank approximations that use a fraction of the original number of parameters. We compare low-rank matrices and tensors to full, unconstrained-rank matrices and tensors on standard semantic similarity tasks for two syntactic constructions: adjectives represented by matrices, and transitive verbs represented by third-order tensors. Using lowrank approximations allows us to reduce the number of the parameters in the models by about 40% for matrices, and by 99% (two orders of magnitude) for the third-order tensors. Despite this reduction in the size of the models, the low-rank matrices and tensors achieve performance comparable to, and occasionally surpassing, the full models. The parameters of these low-rank representations can be optimized directly using standard gradient-based methods, allowing them to be incorporated into existing machine learning models for compositional distributional semantics.
MYCOBIOTA AND CO-OCCRURENCE OF MYCOTOXINS IN GREEN AND ROASTED COFFEE BEANS

A total of 20 samples of green and roasted coffee beans (the same varieties as green coffee beans were used) [Coffea arabica L. (19 samples) and Coffea robusta L. (1 sample)] were collected from the various coffee roasters in Slovakia (2017/2020) and their mycobiota were analyzed. Mycological analysis was carried using standard media with focus on genera Aspergillus and Penicillium. To determine endogenous and exogenous mycobiota the method of direct placing of surface-sterilized coffee beans (green and roasted) on agar plates and the plate dilution method were used. All obtained pure cultures were classified into the genera and identified to the species according to micro- and macromorphological properties. Next the potentially toxigenic isolates were tested on their ability to produce mycotoxins (cyclopiazonic acid, penitrem A, sterigmatocystin, aflatoxins (AFB1, AFG1), ochratoxin A, patulin, roquefortine C, citrinin, and griseofulvin). From green coffee samples with higher isolation frequency (FR%) and relative density (RD%) were the genus Aspergillus (FR 100% and RD 67.39%) and the genus Penicillium (FR 90% and RD 24.60%) recorded. Aspergillus section Nigri was the most widespread in green coffee samples (RD 47.7%). The genus Aspergillus was the most occurred genus in roasted coffee bean samples, too (RD 36.58%; FR 90%). In green and roasted coffee samples were detected mainly producers of aflatoxins (AFB1 and AFG1), cyclopiazonic acid, OA, sterigmatocystin and patulin. Due to the detected presence of mycotoxins in green as well as in roasted coffee bean samples, it is very important to prevent fungal contamination and control of coffee beans before and after roasting process.
Privatization and employment: a study of the Jute industry in Bangladesh

This paper analyzes the effect of privatization upon employment in the Bangladeshi jute textile industry. Privatization was partia and the selection of mills which were privatized was not based on current economic performance. This provides us with a panel data set which permits reliable estimates of the effects of ownership on employment and output. Privatization has reduced employment of all categories of permanent workers significantly, but the extent of employment reduction has been substantially greater among clerical workers and managers as compared to manual workers. This implies that public sector excess employment benefited white-collar workers, who were both better off and better educated, and suggests that public sector behaviour was clientelist rather than welfarist.
Coexistence for a population model with forest fire epidemics

We investigate the effect on survival and coexistence of introducing forest ﬁre epidemics to a certain two-species competition model. The model is an extension of the one introduced by Durrett and Remenik ( Ann. Appl. Probab. 19 (2009) 1656–1685), who studied a discrete time particle system running on a random 3-regular graph where occupied sites grow until they become sufﬁciently dense so that an epidemic wipes out large clusters. In our extension we let two species affected by independent epidemics compete for space, and we allow the epidemic to attack not only giant clusters, but also clusters of smaller order. Our main results show that there are explicit parameter regions where either one species dominates or there is coexistence; this contrasts with the behavior of the model without epidemics, where the ﬁtter species always dominates. We also discuss the survival and extinction regimes for the model with a single species. In both cases we prove convergence to explicit dynamical systems; simulations suggest that their orbits present chaotic behavior.
International Journal of Renewable Energy Development

The United States Environmental Protection Agency (EPA) has reported that consumption of fossil fuels and their products has contributed about 65% of the global greenhouse gas emission. Therefore, it is expedient to look for alternative energy sources for an eco-friendly environment. The EPA recommended using biomass energy as a promising stabilization option to alleviate global climate change. This study focused on developing composites fuel briquettes from a blend of carbonized corncob and banana stalk. Carbonization was carried out at 380 oC, while 60 min was adopted as the residence time. Briquettes were manufactured at different blending ratios (90CC:10BS, 80CC:20BS, 70CC:30BS, 60CC:40BS and 50CC:50BS of corncob: banana stalk, respectively) and compaction pressures (50, 70 and 90 kPa) using gelatinized starch as binder. The manufactured briquettes' calculated and actual calorific values varied between 18.98-22.07 MJ/kg and 20.22-23.12 MJ/kg, respectively, while shatter indices were in the range of 38.22-89.34%. The compressed and relaxed densities of the fuel briquettes were in the range of 0.32-1.39 g/cm3 and 0.22-1.02 g/cm3, respectively. The relaxation ratio and water resistance properties varied between 1.112. 21 and 11-23 min, respectively. Analyses of the results revealed that compaction pressure, blending ratio, and particle size substantially affect the combustion and physico-mechanical characteristics of the manufactured fuel briquettes. When optimum combustion and physico-mechanical properties are required, a sample made from 90CC:10BS (S1) is recommended for use. The fuel briquettes manufactured in this study possess the required thermal and physico-mechanical properties of solid fuel; therefore, it is recommended for different applications.
Are neutral roots in Uyghur really neutral? Evaluating a covert phonemic contrast

This paper looks at the case of so-called neutral roots in Uyghur (Turkic: China), whose idiosyncratic behavior with respect to the backness harmony system has been analyzed as stemming from a covert vowel contrast. Based on considerations of the structural properties of the language and the results of an experimental study, we suggest that an analysis based on lexical exceptionality is more parsimonious than the traditional analysis, unifying the treatment of neutral roots with other cases of exceptionality in the harmony system and accounting for a relationship between the patterning of roots and their frequency. We close by discussing implications for covert contrast analyses in general.
·Dynamic modeling and optimal control of stone-carving robotic manipulators

This paper introduced the inverse linear quadratic (ILQ) theory into the stone-carving robotic manipulators (SCRM) control system. First, we deduced the dynamic equation and state-space equation of the SCRM system with the Lagrange method. Then, the ILQ theory was used to achieve the desired closed-loop poles assignment of the system. To simplify the design process and meet the requirement of practical use, the state feedback optimal control law was determined by an improved ILQ design method. The proposed control scheme has the explicit capacity to achieve the desired joint angle and joint torque control performances, with fewer external disturbances and no sensitivity to changing model parameters. The effectiveness of the proposed control scheme compared with the traditional control strategies is shown in the simulation results. Thus, the vibration of the joint torque during the manufacturing process can be greatly reduced.

Asymmetric flooding as a tool for foreign influence on social media

Research on Russian troll activity during the 2016 US presidential campaign largely focused on divisive partisan messaging. Here, we document the use of apolitical content—content that could counteract mobilization efforts and escape detection in future campaigns. We argue this resembled techniques used by autocratic regimes domestically, in “flooding” social media with entertainment content to distract from and displace mobilizing messaging. Using automated text analysis and hand coding to construct a timeline of IRA messaging on Twitter, we find left-leaning trolls posted large volumes of entertainment content in their artificial liberal community and shifted away from political content late in the campaign. Simultaneously, conservative trolls were targeting their community with increases in political content. This suggests the use of apolitical content might be an overlooked strategy to selectively manipulate levels of attention to politics.
Diseño y validación de la escala de juegos y emociones para niños ( GES-C ) Design and validation of games and emotions scale for children ( GES-C )

Several instruments exist to measure emotional experiences during physical activity. However, these instruments are designed on a clinically basis and use mood concepts rather than emotions. Moreover, these instruments are designed and validated only with adult samples. An instrument is needed to study the emotional experiences of schoolchildren when participating in games or sports. Therefore, the aim of this study was to design and validate the Games and Emotions Scale for Children to assess the intensity of emotions (positive or negative) of schoolchildren in physical education classes, when players participated in games of different motor action domains, with or without competition (winner or loser). A total of 293 students from four Spanish primary schools participated. Ten experts evaluated the content. The results of confirmatory factor analysis, reliability and validity (convergent and discriminant) yielded two factors and satisfactory fit indices. Acceptable reliability and validity values were obtained. The present study suggests that the GES-C is a structurally valid and reliable instrument for measuring emotional intensity in motor games, both in an educational and sport context. Thus, the results could benefit both teachers and coaches, allowing them to know the type of emotional experiences generated by their motor practices. Cita: Alcaraz-Muñoz, V. ; Alonso, J.
