Authors: Wellia Diana Vanda , Alvionita Febby , Arief Syukri
Published: June 2020

The surface of ultrahydrophobic glass has been successfully prepared using the combination of TiO2 and stearic acid. TiO2 was used to increase the surface roughness, while stearing acid was a surface modifier. The peroxo sol-gel method has been used to synthesize TiO2 precursors on the glass layer followed by modification of stearic acid. The maximal water contact angle of 141o has been obtained for the composition of 0.4 grams of stearic acid and 20 mL of ethanol (NKTS-2%). AFM analysis showed the roughness of NKTS-2% is 4,15 nm, which was greater than the pure glass. FTIR analysis also showed vibration of C=O (carbonyl) at 1697cm-1 indicating the chemical interaction between TiO2 and stearic acid. EDX spectrum analysis of TiO2/stearic acid (TiO2/C18H36O2) showed the existence of titanium, oxygen, and carbon. The optimum sample (NKTS-2%) showed a good transparency and self-cleaning properties compared to pure glass

This research   study  about tiofen based organic dyes with D-π-A type as sensitizer on DSSC. The dyes were varied with the acceptor chain and were given names of dyes 1 to 10. The dye with the smallest band gap was added with the electron withdrawing and donating groups. The computational study used the hyperchem package with the AM1 calculation method. The result showed that  dye 8 has the smallest band gap is 4,9 eV and dipole moment is 9,3 D. The effect of adding Cl as an electron withrawing group (EWG) can reduce the band gap value to 4,7 eV. The conclusions are that dye 8 is more potential as sensitizer on DSSC and the addition of Cl as EWG can improve the light harvesting efficiency.

Development of Biopolyesters (PHA) as Part of the Swiss Priority Program in Biotechnology
Authors: Zinn Manfred
Published: June 2020

The Swiss Priority Program in Biotechnology of the Swiss National Science Foundation that lasted between 1992 and 2001 had a boosting effect on many biotech disciplines and on the developments of polyhydroxyalkanoates (PHAs) in Switzerland in particular. The funding organization led
by Prof. Oreste Ghisalba enabled a better understanding of the PHA biosynthesis and the development, as well as the implementation of novel bioprocesses (e.g. two-phase fermentations, multiple nutrient limited growth conditions, multi-stage chemostats, and product formation in different
host organisms). However, production of PHA in Switzerland appeared to be impossible for cost reasons due to the strong competition from cheaper, petrol-based plastics. The recent reports on environmental issues with non-degradable plastics has triggered a general change in the perception
of biodegradable plastics, giving them an added value and thus justifying a higher price. Ongoing research focuses on the sustainable production of PHAs using carbon waste streams, synthesis gas or even CO2
Can Polarity-Inverted Surfactants Self-Assemble in Nonpolar Solvents?
Authors: Carrer Manuel , Skrbic Tatjana , Bore Sigbjørn Løland , Milano Giuseppe , Cascella Michele , Giacometti Achille
Published: June 2020

We investigate the self-assembly process of a surfactant with inverted polarity in water and cyclohexane using both all-atom and coarse grained hybrid particle-field molecular

dynamics simulations. Unlike conventional surfactants, the molecule under study proposed in a recent experiment (M. Facchin et al., RSC Adv. 2017, 7, 15337–15341) is

formed by a rigid and compact hydrophobic adamantane moiety, and a long and floppy triethylene glycol tail. In water, we report the formation of stable inverted micelles with the adamantane heads grouping together into a hydrophobic core, and the tails forming hydrogen bonds with water. By contrast, multi-microsecond simulations do not provide evidence of stable micelle formation in cyclohexane. Validating the computational results by comparison with experimental diffusion constant and small-angle neutron scattering intensity, we show that at laboratory thermodynamic conditions the mixture resides in the supercritical region of the phase diagram, where aggregated and free surfactant states co-exist in solution. Our simulations also provide indications about how to escape this region, to produce thermodynamically stable micellar forms.
Experimental Evidence for a General Model of Modulated MOF Nanoparticle Growth
Authors: Marshall Checkers R. , Staudhammer Sara , Brozek Carl
Published: June 2020

Nanoparticles of metal-organic frameworks (nanoMOFs) boast superior properties compared to their bulk analogs, yet little is known about how common synthetic parameters dictate particle sizes. Here, we provide experimental evidence for the “seesaw” model of nanoMOF growth. Solution acidity, ligand excess, and reactant concentrations are decoupled and shown to form the key independent determinants of nanoMOF sizes, thereby validating the proposal that nanoMOFs arise from coupled equilibria involving ligand deprotonation and metal-ligand complexation. By achieving the first demonstration of a seesaw relationship between nanoMOF sizes and ligand excess, these results provide further proof of the model, as they required deliberate manipulation of relationships outlined by the model. Exploring the relative impacts of these parameters reveals that ligand excess has the greatest ability to decrease sizes, although low acidity and high concentrations can exhibit similar effects. As a complement to existing models of polymer formation and crystal growth, the seesaw model therefore offers a powerful tool for reliable control over nanoMOF sizes.

Published: June 2020

Preeclampsia (PE) is a major reason for maternal morbidity and mortality globally. Studies showed that body mass index (BMI) is one of the risk factors of PE. In this study, the BMI and physiological and hematological profile were associated with predicting the severity of preeclampsia, so that proper counseling and antenatal care could be given for good pregnancy outcome. The study was carried out on 100 healthy normotensive pregnant and 100 diagnosed preeclamptic women. Healthy pregnant and PE were categorized into three groups based on BMI, on WHO criteria. BMI group 1 (<25 Kg/m2) considered as normal, group 2 (25 – 30 Kg/m2) as over-weight and group 3 (>30 Kg/m2) obese. Systolic blood pressure (SBP), diastolic blood pressure (DBP), hemoglobin (Hb), white blood corpuscles (WBC), red blood corpuscles (RBC) and platelets were compared in control and PE groups. Then the respective control groups were compared with PE groups. The prevalence of overweight was more in PE groups when compared to normotensive pregnancy (P=0.004). Statistically, a significant difference was not observed in BMI group1, group 2 and group 3 of control and PE in relation to SBP, DBP, Hb, WBC, RBC and platelets. But a statistically significant difference was made when respective control groups were compared with PE (P<0.005). BMI does not have any statistically significant association with SBP, DBP, Hb, WBC, RBC and platelets. BMI could not be considered as a predictor or severity of preeclampsia.

Perceptions of Pharmacy Involvement in Social Prescribing Pathways in England, Scotland and Wales
Authors: Taylor Denise , Nicholls Gina M , Taylor Andrea DJ
Published: June 2020

Social prescribing is increasingly viewed as a non-pharmacological option to address psychosocial consequences of social isolation, loneliness and bereavement; key contributors to poor mental health and wellbeing. Our study explored experiences and attitudes of pharmacists and pharmacy technicians to social prescribing in England, Scotland, and Wales, using an on-line survey. (Ethical approval, University of Bath, November 2017). The electronic survey was distributed to pharmacists registered with Royal Pharmaceutical Society local practice forum network groups in England, Scotland, and Wales, and pharmacy technicians via social media platforms. Data were analysed using descriptive statistics and free text by thematic analysis. One hundred and twenty respondents took part in the survey; (94.6% pharmacists and 5.4% pharmacy technicians). Responses indicated a lack of knowledge and experience with social prescribing; however, there was enthusiasm for pharmacists and the wider pharmacy team to be involved in local social prescribing pathways. Respondents believed they were well positioned within the community and consequently able to be involved in identifying individuals that may benefit. Barriers to involvement, included time, funding and training while enablers were pharmacist skills and the need within the community for social prescribing. There is a willingness in pharmacy, to be involved in social prescribing, however further research is required to enable pharmacy to be full participants in social prescribing pathways.
Understanding Gendered Perspective to Corruption: Evidence from Pakistan
Authors: Ilyas Muhammad , Rabia Rasheed  , Faiz Rafia
Published: June 2020

This study focuses on the debate that whether women are as corrupt as men, or their propensity to corruption is less than their male counterparts on account of their soft gender? It also encompasses the dynamics of networking, with particular emphasis on sifarish (use of influence for undue benefits)  and networking in gender perspective. Are women less corrupt than men? Do the sifarish and networking have gender biasness, how women become part of these networks and what role they play therein? These are the questions addressed in this study. An interpretive approach of qualitative research has been adopted keeping in view the subjective nature of networking and corruption. Semi-structured interviews from seventeen General / Senior Managers of public sector organizations were conducted to get their input on the research questions, middle management of public sector has been selected with a view that they have immediate exposure to corruption occurrences in the society. In addition to it, in depth review of the relevant available literature has been made. It has been concluded that apparent image of women being less susceptible to corruption is not related with their sex or gender, rather it is due to their less exposure to business and economic world which, even as of today, is dominated by men This study will add to the literature on role of gender in corruption, sifarish, networking and favoritism in the Pakistani context. This will also help management practitioners in working out their strategies in defining the role of women in the anti-corruption campaigns in business and political sectors. This study has acquired feedback from the middle management employees belonging to public sector organizations as they are directly related with formation and implementation of policies, which is also a sampling limitation. Future research should be carried out on diverse samples covering private organizations and non-professional people.

Published: June 2020

This study intended to explore the implementation of promoting “energy education” in Taiwan’s elementary schools. The research adopted a questionnaire (Likert five-point scale) from teachers’ view in three dimensions to construct examination. The 45 participants come from 10 different primary schools distributed across Taiwan, which participate in energy education program in the second period (2015-2017). The data was analyzed by ANOVA, mean and standard deviations of the viewpoints of the participants in the energy education learning achievement of the primary schools. The first findings in this research is, the program of energy education was most effective in “energy attitude” (M=4.282, SD=0.814), followed by “energy awareness” (M=4.049, SD=0.720) and “energy behavior” (M=3.983, SD=0.875). It shows that students have positive energy attitude, but they were relatively weak at energy saving behavior. Secondly, there is statistically significant difference in overall students learning performance with urban areas are higher than rural areas. Finally, it is suggested that in addition to strengthen energy attitudes and energy awareness, we should encourage students to take action in save energy in their daily life. Furthermore, we should invest more resources to rural areas to balance the students’ performances between urban and rural areas.
Numerical Analysis of the Influence of Bolt Set on the Shear Resistance of Jointed Rock Masses
Authors: Wang Yan-Ping , Xiong Liang-Xiao
Published: June 2020

Bolt reinforcement is a standard reinforcement method for jointed rock masses. However, regarding rock anchoring, the mechanical characteristics of the joint surface, as well as the angle between the bolt and the joint sliding surface, are important factors that affect rock support. Therefore, to understand the influence of a set angle, length, normal load, and other conditions that affect the shear strength of bolt joints, this study uses numerical software to establish the shear sliding model of bolt rock masses and analyzes the influence of the setting conditions of the bolt on the shear strength of a bolt rock mass, which can be done by changing the setting method of the bolt and normal mechanical conditions of the sliding surface. The results show that the shear strength of the anchor joint is not affected after the anchor reaches a certain length. The angle of the anchor strongly influences the shear strength of the anchor joint, and the shear strength curve is V-shaped, where the anchor angle is less than 90°. Moreover, the shear strength curve indicates a downward trend when the anchor angle is greater than 90°, and the shear strength of the anchorage joint increases with the increase of the normal load. Under the same anchor length (4 cm) in the anchor angle and shear strength coordinate system, the shear strength curve of the single anchor is above the shear strength curve of the double anchor, which is exclusively in the local anchor angle section under the condition of a large normal load and a large anchor angle. The shear strength curve of the double anchor is above the shear strength curve of the single anchor.

This interdisciplinary paper researches the importance of sustainable hotel engineering and organisation of facilities for the purposes of realisation of a sustainable and responsible hospitality facility business. Considered through the interdisciplinary aspect, at the same time, it represents a research goal with the focus on the segment of youth tourists, who, as existing consumers of low-budget expenditure, are turning into DINKY, as well as the segment of conscious adult consumers in the future. The paper, through a questionnaire, researches the perception of the importance of resource management, with the implementation of innovative technologies by youth tourists’ related attitudes and experiences. The methodology is based predominantly on qualitative research methods and includes analysis and conceptual methodology and survey research methods of youth tourists’ attitudes. The quantitative research was processed by using the statistical methodology combined with techniques of creative thinking formation. The results point to the predominance of importance in which over 90% of respondents confirm the importance of sustainable initiatives and resource management with the following rank: food, water, energy, and waste management. Further analysis implies an opposite attitude where only 52.9% of participants would be willing to pay higher prices for sustainable solutions in hotels. The results and recommendations contribute to knowledge and ideas by recognizing competitiveness of hotels, which design and engineer the business system and operations with support of sustainable technologies in an interdisciplinary way. The paper also contributes to the comprehension of combined and successfully communicated economic and marketing values of sustainable innovations supported by digital technologies.

Violence and sexual exploitation of children must be stopped, because it is a crime against humanity and harms the dignity of children. Sexual violence against children in Indonesia has been classified as an extraordinary crime. The fact of the high sexual violence against children occurred in almost all of Indonesia and also occurred in the city of Surakarta. KAKAK Foundation carries out prevention and trauma healing (recovery) programs for child victims, as a form of contribution in creating the best life order for children. Through the Program, KAKAK Foundation conducted outreach and assistance to 152 victims of sexual exploitation of children in 1999-2004, 110 children, in 2005-2008, and 76 children in 2008-2011. The choice of children participation methods was very important in the prevention and trauma healing program (recovery) of children victims of sexual violence. For this reason, the program "Theater, As a Form of Child Participation in the Prevention and Trauma Healing of Children Victims of Violence and Sexual Exploitation" is carried out. Through theater children victims are actively involved (participative) in expressing their feelings and can voice children's aspirations to others.
Ecuador... 20 años no es nada: a dos décadas del mito dolarizador
Authors: Acosta Alberto , Cajas-Guijarro John
Published: June 2020

A veinte años de la dolarización de la economía ecuatoriana, el debate sobre tal subordinación monetaria es aún insuficiente. Esto motiva al presente artículo a discutir sobre tres cuestiones: cómo la dolarización se originó a partir del traumático salvataje bancario que Ecuador vivió a fines de los años 90; cómo existen varios relatos que intentan sostener al “mito dolarizador” pero que son casi inaceptables (falta de alternativas, mayor crecimiento, herramienta contra la hiperinflación, mayor estabilidad, entre otros); y cómo un origen histórico trágico y múltiples relatos cuestionables llevan al país a aceptar una rígida estructura monetaria que llena su economía de incertidumbres.

Authors: González Calleros Claudia Blanca , Guerrero-García Josefina , Navarro-Rangel Yadira
Published: June 2020

Even though games that focus on the development of logical-mathematical skills aimed at maintaining the attention of children with ADHD currently exist, there are no applications available to learn how to solve mathematical problems. In view of this problem, a serious game was designed and developed to enable children to achieve significant learning in this subject. An evaluation was performed of the interface of a section of the game focusing on the concept of counting. Work was performed with 7 teachers by means of a Wizard of Oz experiment. A CSUQ questionnaire was also used to gather general information on the teachers, such as gender and age. The children’s experience in using the application was also assessed. The study indicates that the current interface is usable, though it requires certain improvements in terms of typography, image design, and color.

Pilot Based Channel Estimation and Synchronization in OFDM System
Authors: Abdul Majed Mahmood Mohmmmed saeed , Omran Buthaina Mosa
Published: June 2020

Channel estimation and synchronization are considered the most challenging issues in Orthogonal Frequency Division Multiplexing (OFDM) system. OFDM is highly affected by synchronization errors that cause reduction in subcarriers orthogonality, leading to significant performance degradation. The synchronization errors cause two issues: Symbol Time Offset (STO), which produces inter symbol interference (ISI) and Carrier Frequency Offset (CFO), which results in inter carrier interference (ICI). The aim of the research is to simulate Comb type pilot based channel estimation for OFDM system showing the effect of pilot numbers on the channel estimation performance and propose a modified estimation method for STO with less number of pilot to mitigate ISI effect. Channel estimation is simulated for different pilot number with 16QAM modulation in Ped-A Rayleigh channel. The STO effect assumed less than the cyclic prefix length to minimize ISI and maintain the orthogonality between subcarriers. The simulation results show that the high number of pilots are needed to achieve good channel estimation in case no synchronization used while similar results are achieved with smaller number of pilots if the propose modification on the synchronization method are used aligned with the channel estimation. The proposed system is evaluated in terms of BER and SNR.
GIS as A Tool for Expansive Soil Detection at Sulaymaniyah City
Authors: Rashed Kamal Ahmad , Hussein Alle A
Published: June 2020

Geotechnical engineering like any other engineering field has to develop and cope with new technologies. This article intends to investigate the spatial relationships between soil’s liquid limit (LL), plasticity index (PI) and Liquidity index (LI) for particular zones of Sulaymaniyah City. The main objective is to study the ability to produce digital soil maps for the study area and determine regions of high expansive soil. Inverse Distance Weighting (IDW) interpolation tool within the GIS (Geographic Information System) program was used to produce the maps. Data from 592 boreholes for LL and PI and 245 boreholes for LI were used for this study. Layers were allocated into three depth ranges (1 to 2, 2 to 4 and 4 to 6) m. A total of 1396 observations were used for producing the maps for both LL and PI, and 371 data for LI. Based on the results, the IDW method gives reasonable predictions depending on the results of R2 and RMSE. The results also showed that the study area has relatively large zones of high expansive soil that must be taken into considerations before performing any construction activity. These maps are essential for helping geotechnical engineers in making decisions and visualizing soils’ behaviors.

The complex cartography of the Khmelnitskaya APS 30-kilometer zone (the total area of 282.6 thousand ha) was carried out during the elaboration of project according to the MAGATE demands. The present geobotanical map of zone was created in the scale 1 : 100 000. The ecological-phytocoenotical (dominant) vegetation classification was taken as a basis of the map's legend. The legend includes 27 numbers and 6 variants, represented by the boreal forest (11.6 % of area), nemoral forests (8.4 %), meadows (2.4 %), hydrophyte communities (3.2 %), agro- and urbo-communities (61.9 %) and young forest plantations (4.4 %). The characteristic of prevailing community types is given. Influence of the economic activity on the vegetation cover is shown. The geobotanical map can be used for both further monitoring and management of the forest economy with the aim of increasing the ecosystems stability against the external influences.

Menjadi suatu polemik adalah ketika orang-orang menganggap bahwa konsep TUHAN didalam pribadi dan pekerjaan-Nya padaPerjanjian Lama adalah suatu konsep yang tidak pasti atau abstrak. Namun, peristiwa Musa saat Ia naik keatas gunung Sinai seperti yang tertulis pada Keluaran 19:1-25 telah mencerminkan mengenai beberapa makna teologis dari pribadi ilah yang ada pada waktu itu serta pekerjaan-Nya. Konsep yang dahulunya tidak pasti, kini melalui penelitian yang telah penulis laksanakan melalui metode literature, telah membuktikan bahwa konsep Ilah pada Perjanjian Lama terbukti pasti dan konsisten.Menjadi suatu polemik adalah ketika orang-orang menganggap bahwa konsep TUHAN didalam pribadi dan pekerjaan-Nya padaPerjanjian Lama adalah suatu konsep yang tidak pasti atau abstrak.

Chloroquine and hydroxychloroquine as antimalarials and antivirals against SARS-CoV-2: The hemin factor
Authors: Herraiz Tomás
Published: June 2020

Drugs are urgently needed for COVID-19. In that context, the antimalarial drugs chloroquine and hydroxychloroquine are being used based on their antiviral action against SARS-CoV-2 in vitro and results from early clinical studies. The antiviral action of these drugs relays on their accumulation into lysosomes and acidic endosomes that increase pH, making more difficult virus entry and replication. In malaria, these drugs accumulate into the Plasmodium acidic vacuole, and interact with hemin released from hemoglobin, inhibiting its crystallization to hemozoin (β-hematin). Hemin is toxic for the parasite (antimalarial effect). Recent results have shown that chloroquine inhibits β-hematin formation, and increases soluble free hemin that is involved in oxidative reactions and inhibition of cysteine proteases, underlining the chloroquine effects mediated by hemin. Therefore, antimalarial and antiviral actions of these drugs differ by the hemin factor. However, could hemin play a role in the antiviral action? Infections by SARS-CoV-2 and acute respiratory distress syndrome (ARDS) induce local lung hemorrhages releasing cell-free hemoglobin which is oxidized and releases free hemin. Besides, SARS-CoV-2 invades epithelial cells of the lung, which express non-erythroid hemoglobin. Chloroquine/hydroxychloroquine could hypothetically interact with that hemin/hemoglobin affecting the host and virus. It could result in oxidative reactions and inhibition of cysteine proteases necessary for viral progression. Remarkably, hemin also exerts antiviral actions against a number of viruses, supporting a possible role in the antiviral effects. Hemin is commonly used for the treatment of acute porphyria attacks, and this might be relevant in possible cases of acute porphyria attacks and COVID-19 treated with antimalarial drugs. Finally, it could be worth of testing the antiviral action of chloroquine/hydroxychloroquine and hemin combined, and that of hemin alone against SARS-CoV-2 (COVID-19).
No Item is an Island Entire of Itself: An Analysis of Construct Validity of Player Motivation Questionnaires
Authors: Hughes Nathan , Cairns Paul
Published: June 2020

[Preprint Version] There are many player motivation questionnaires. Whilst they converge in anticipated ways, such as multiple Immersion sub-scales, they also diverge, with unique sub-scales such as Aesthetic. This suggests unclear overlap in the constructs that underpin these questionnaires, indicating a need to understand their combined construct validity. However, to date there has been no such exploration. In this study, 11 questionnaires with 45 total sub-scales were compiled into one 177 item survey (N = 1683). Construct validity was explored through three exploratory analyses. Results indicated seemingly related sub-scales often measured unrelated constructs, and sub-scales strongly overlapped despite their high volume and supposed diversity. An Exploratory Factor Analysis of all 177 items found a 19-factor solution, further suggesting considerable overlap. Overall, there are concerning shortcomings in motivation questionnaires. To advance player research, either a more robust theoretical basis is needed, or the utility in creating 'general' motivation questionnaires requires reconsidering.

Published: June 2020

Rencana pemenuhan air Kota Cilegon dan sekitarnya hingga tahun 2035 harus direncanakan sejak sekarang untuk mengantisipasi terjadi kekurangan air. Dengan meningkatnya jumlah penduduk dan aktivitas pembangunan di Kota Cilogon, akan berdampak pada peningkatan jumlah kebutuhan airnya. Kebutuhan air pada tahun 2015 adalah 3,74 m3/dt dan terus meningkat hingga 5,78 m3/dt pada tahun 2035. Disisi lain, dengan potensi ketersediaan air yang terbatas, yang bersumber dari Waduk Krenceng yang saat ini ada ditambah dengan rencana pembangunan Bendungan Cidanau yang telah mendapatkan penolakan dari Para Pemerhati Lingkungan DAS Cidanau maka menyebabkan kendala pemenuhan kebutuhan air di Kota Cilegon di masa yang akan datang. Dari 3 (tiga) skenario rencana pemenuhan kebutuhan air di Kota Cilegon hingga tahun 2035, terpilih skenario 1, yaitu dengan membangun Bendungan Pasir Kopo dan Cidanau Alternatif 3, serta mengoptimalkan pemanfaatan air dari S. Cipasauran. Terpilihnya skenario 1, didasarkan pada kriteria analisis yang mencakup kesiapan dokumen perencanaan, terakomodasinya dalam perencanaan tata ruang, waktu pelaksanaan, panjang saluran pembawa dan rencana pengoperasiannya. Dengan ketersediaan air yang ada sekarang, yaitu sebesar 2,1 m3/dt dengan ditambah alokasi dari Bendungan Pasir Kopo 1,83 m3/dt, Bendungan Cidanau Alt.3 (0,35 m3/dt, optimalsasi pemanfaatan air dari S. Cipasauran (1,5 m3/dt), maka pada tahun 2035 kebutuhan air untuk Kota Cilegon dapat dipenuhi.

Please do not cite this preprint.The Talking Together community-engagement pilot project brought together pairs of autistic and non-autistic strangers to: (1) talk about their experiences of loneliness in their local city; and (2) think about potential, co-produced responses to the problem. The project had evolved as a secondary aim, from an initial need to acquire naturalistic conversation data for my linguistic PhD research investigating a theoretical reframing of autistic language use as ‘different’ rather than ‘deficient’. The desire to make the data collection a meaningful experience for the participants in its own right was central to the research design, and so the Talking Together loneliness project was devised as a way to achieve this. However, it was not until the research was under way that the potential for valuable, immediate impact became apparent. This article reflects on the successes and challenges of the Talking Together pilot as a piece of autistic-led participatory research, and explores how the principles of engaged, participatory research can be applied so as to maximize impact, even where engagement may not be a primary aim. It also explores the ‘participatory’ nature of participatory research where the researcher belongs to the marginalized stakeholder group.Keywords: loneliness, autism, conversations, participatory design, data collectionKey messages • Engaged research can enrich linguistic data collection on multiple levels, not least in making the experience more meaningful for stakeholder research participants. • Facilitating strangers to come together to talk about their experiences of loneliness can generate qualitative data on loneliness, while at the same time contributing to reducing the impact of loneliness, as an act of radical ‘world building’. • Supporting autistic people to access doctoral research opportunities is one way of broadening the body of participatory autism research.
Consistent Verbal Labels Promote Odor Category Learning
Authors: Vanek Norbert , Soskuthy Marton , Majid Asifa
Published: June 2020

Recent research shows that speakers of most languages find smells difficult to abstract and name. Can verbal labels enhance the human capacity to learn smell categories? Few studies have examined how verbal labeling might affect non-visual cognitive processes, and thus far very little is known about word-assisted odor category learning. To address these gaps, we tested whether different types of training change learning gains in odor categorization. After four intensive days of training to categorize odors that were co-presented with arbitrary verbal labels, people who learned odor categories with odor-label pairs that were more consistent were significantly more accurate than people with the same perceptual experience but who had odor-label pairs that were less consistent. Both groups’ accuracy scores improved, but the learning curves differed. The context of consistent linguistic cuing supported a steady increase in correct responses from the onset of training. However, inconsistent linguistic cuing delayed the start of approximating to target odor categorization. These results show that associations formed between odors and novel verbal labels facilitate the formation of odor categories. We interpret this as showing a causal link between language and olfactory perceptual processing in supporting categorization.
