Published: November 2022

This research aims to ensure the active role of the Bagak Sahwa village community in making decisions on tourism by using the environmental area to obtain a fair share of income from tourism activities. Bagak Sahwa tourism village is expected to implement Community Based Tourism (CBT) effectively. However, the implementation by the local community has not been conducted as mandated in Law No. 10 of 2009. In some cases, it can even lead to community conflicts. The results showed that community participation in developing the tourism village potential was still low. The low quality of human resources also influenced this situation, and the resident-focused more on the agricultural sector. The road access is in poor shape, insufficient facilities, and infrastructure supporting tourism activities, the promotion of tourism objects is still deficient, and the quality and quantity of human resources are still low. The Social Entrepreneur model’s presence has impacted a shift in society’s perspective socially and economically. However, the Village community still upholds their ancestors’ language and behavior patterns. The administrators involving the local community transmit knowledge based on these findings. Therefore, the local community is educated to actively participate in developing the village. They can collaborate with new things by involving millennials in tourism village activities to maintain local culture and wisdom.

Example of applying a Health, Safety and Environment management system in cetacean research: Case study from a satellite tagging field accident
Authors: Hassel Lucas B. , Zerbini Alexandre Novaes , Andriolo Artur , Cabete Ricardo
Published: November 2022

Satellite telemetry is a powerful method to study the movements and habitat use of cetaceans. The deployment of transmitters is usually conducted using remote techniques and involves close approaches to the target animals. The present study reports on an accidental collision between a female humpback whale and an inflatable boat, which occurred on 7 October 2010 off the coast of Brazil. At the time of the accident, the boat was occupied by four crew members: the tagger, the photographer, the driver and an observer. This collision resulted in head trauma and severe brain injury to the photographer. It also resulted in changes of the tagging deployment procedures and the implementation of a Health, Safety and Environment (HSE) management system. The objective of this work is to report on this accident and describe procedures adopted to assess and minimise risks. Changes and updates in deployment protocols are viewed as improvements to minimise accidents during marine mammal tagging operations. Some of these improvements were also discussed and implemented by other organisations. Accidents such as the one reported here can and should be prevented. However, when they occur, they provide an opportunity to assess and correct unanticipated deficiencies in field work procedures.

Published: November 2022

New opportunities for vehicular Internet of Things (IoT) services using current and modern rational transportation system, along with newer challenges for vehicular ad-hoc networks (VANETs). Along with improved network performance, a workable and trustworthy security system is required to handle trust management while maintaining user privacy. A key technology for extremely dependable, low-latency wireless communication services is the newly developed 5G mobile communication system. Additionally, the software-defined network (SDN) design allows for network control and worldwide data collection within the 5G-VANET. As a result, real-time IoT services for monitoring and reporting on transportation can be effectively supported. Both open the door for a cutting-edge automobile security system.This paper investigates the security and privacy issue in the transportation system and the vehicular IoT environment in SDN-enabled 5G-VANET. A blockchain-based security framework is created to support the vehicular IoT services, such as real-time cloud-based video reporting and trust management on vehicular messaging, due to the decentralised and immutable nature of blockchain. The 5G-VANET model with SDN support and the framework's scheduling processes are specifically illustrated in this study. The outcomes of the numerical simulation also demonstrate that it is possible to detect malicious vehicular nodes or communications while maintaining acceptable overhead and network performance impacts in large-scale scenarios. We show how our design considerably ensures a secure and reliable vehicle IoT environment with user privacy preserved through case studies and theoretical analysis.

Decolorization of Boron-Based Wood Preservatives by Ozonation for Recycling: Optimization of Process Parameters
Authors: Yanchimpee Pantakan , Thawornchaisit Usarat
Published: November 2022

Preservation of sawn timber from rubber trees with a water-soluble mixture of boric acid and borax generates a large quantity of colored wood preservative solutions and carries toxic metals, especially boron.  To save costs, millers commonly reuse the colored mixtures in successive preservation cycles but regularly add boric acid and borax to maintain boron levels. However, this strategy affects both the color and the economic value of the treated wood. This paper presents a new strategy to treat the colored mixture of waterborne preservative solutions using ozonation for recycling purposes.  At optimum conditions which are determined by response surface methodology, very high color removal (96 - 97 %) is achieved from ozone treatment of the wood preservatives with an initial COD concentration of 2,250 ± 40 mg/L and solution pH of 3.59 ± 0.02 for 65 min reaction time. The effluent can be reused in successive preservation cycles without degrading the wood quality in terms of the color of the processed timber and boron penetration in the end grain as well as the sides of the wood. Ozone treatment shows to be a promising color removal technology for sawn rubberwood industry, aimed at the reuse of waterborne preservatives, resulting in direct environmental and economic benefits.
HIGHLIGHTS

Application of ozone (O3) can be a clean technology to treat the color of aqueous solutions for in-process recycling in sawn rubberwood industry
Box-Behnken design and Response Surface Methodology applied to find the optimum conditions for color removal from the mixture of boric acid and borax
Recycling the mixture of boric acid and borax in a subsequent wood preservation operation gave very promising results

Published: November 2022

A rosácea é uma doença de pele inflamatória crônica e acredita-se que seu mecanismo de ação, ainda que não comprovado, origina-se da desregulação do sistema imune inato, existindo outros fatores extrínsecos que podem desencadear o aumento dos sintomas. A mesma é dividida em quatro subtipos e cada um deles possui suas características: eritemato-telangiectasia, papulopústular, fimatosa e ocular. Através de estudos foi possível estabelecer uma relação entre a microbiota, tanto da pele quanto do intestino, onde verificou-se uma disbiose causada por essa doença. Esse desequilíbrio microbiano ocasionou estudos referentes ao uso de probióticos para o tratamento de doenças como a acne, rosácea, dermatite atópica e psoríase, atuando na redução dos processos inflamatórios de diferentes formas desde imunomodulação até proteção do microbioma.

O tratamento baseia-se no uso oral e tópico, e se faz importante analisar o microbioma dos pacientes, em razão de possuírem aspectos particulares que são definidos de acordo com fatores como: estresse, alimentação, consumo de álcool e uso de medicamentos. Analisando as ações dos probióticos na pele, seus mecanismos de ação e os possíveis benefícios, notou-se que a associação pode ser eficaz para o tratamento dessa doença, apresentando melhora dos sintomas e, consequentemente, da autoestima dos pacientes, juntamente com o crescimento pela busca de novas alternativas preventivas.

Published: November 2022

Orthogonal frequency division multiplexing (OFDM) has become an indispensable part of waveform generation in wideband digital communication since its first appearance in digital audio broadcasting (DAB)and it is indeed in use. These descriptions are simplified version of the detailed descriptions provided by 3gpp. It is a superior technology for the high-speed data rate of wire-line and wireless communication systems. The OFDM has many advantages over other techniques such as its high capacity and immunity against multipath fading channels. However ,one of the main drawbacks of the OFDM system is the high-peak-to-average power ratio (PAPR) that leads the system to produce in-band distortion and out-of-band radiation because of the non-linearity and reduces its efficiency is the distortion of the signal caused at the High Power Amplifier (HPA) of a transmitter . Therefore, it is highly desirable to reduce the PAPR of an OFDM signal. For this, numerous techniques have been proposed to overcome the PAPR problem such as i) selective mapping(SLM) ii) partial transmit sequence (PTS), iii) clipping, iv) clipping and filtering. In this paper, the PTS technique was analytically reviewed as one of the important methods to reduce the high PAPR problem. Simulations are used to analyze the efficiency of the techniques used which signifies OFDM to be providing much better PAPR reduction and a better Bit Error Rate (BER) . From simulation results clipping method shows good PAPR reduction with significant amount of BER degradation. Clipping and filtering method shows slight increase in PAPR with small degradation in BER performance than Clipping method and both methods are computationally less complex. PTS provides good PAPR reduction with high computational complexity.
In-Depth Analysis and Systematic Literature Review on Risk Based Access Control in Cloud
Authors: Hussain Sadia , Islam M. Hasan , Abbas Haider
Published: November 2022

Security in Cloud is one of the most foremost and critical feature, which can ensure the confidence of the Scientific community on Cloud environment. With the dynamic and ever changing nature of the Cloud computing environment, static access control models become obsolete. Hence, dynamic access control models are required, which is still an emergent and underdeveloped domain in Cloud security. These models utilize not only access policies but also contextual and real-time information to determine the access decision. Out of these dynamic models the Risk-based Access control model, estimates the security risk value related to the access request dynamically to determine the access decision. The exclusive working pattern of this access control model makes it an excellent choice for dynamically changing environment that rules the cloud’s environment. This paper provides a systematic literature appraisal and evaluation of risk-based access control models to provide a detailed understanding of the topic. The contributions of selected articles have been summarized. The security risks in cloud environment have been reviewed, taking in the account of both Cloud Service Provider and Cloud Customer perspectives. Additionally, risk factors used to build the risk-based access control model were extracted and analyzed. Finally, the risk estimation techniques used to evaluate the risks of access control operations have also been identified.
Quantifying the Theory Vs. Programming Disparity using Spectral Bipartivity Analysis and Principal Component Analysis
Authors: Meghanathan Natarajan
Published: November 2022

Some students in the Computer Science and related majors excel very well in programming-related assignments, but not equally well in the theoretical assignments (that are not programming-based) and vice-versa. We refer to this as the "Theory vs. Programming Disparity (TPD)". In this paper, we propose a spectral bipartivity analysis-based approach to quantify the TPD metric for any student in a course based on the percentage scores (considered as decimal values in the range of 0 to 1) of the student in the course assignments (that involves both theoretical and programming-based assignments). We also propose a principal component analysis (PCA)-based approach to quantify the TPD metric for the entire class based on the percentage scores (in a scale of 0 to 100) of the students in the theoretical and programming assignments. The spectral analysis approach partitions the set of theoretical and programming assignments to two disjoint sets whose constituents are closer to each other within each set and relatively more different from each across the two sets. The TPD metric for a student is computed on the basis of the Euclidean distance between the tuples representing the actual numbers of theoretical and programming assignments vis-a-vis the number of theoretical and programming assignments in each of the two disjoint sets. The PCA-based analysis identifies the dominating principal components within the sets of theoretical and programming assignments and computes the TPD metric for the entire class as a weighted average of the correlation coefficients between the dominating principal components representing these two sets.

Published: November 2022

Nowadays, Fog architecture or Edge architecture is becoming a popular research trend to distribute a substantial amount of computing resources, data processing and resource management at the extreme edge of the wireless sensor networks (WSNs). Industrial communication is a research track in next generation wireless sensor networks for the fourth revolution in the industrial process. Adopting fog architecture into Industrial communication systems is a promising technology within sensor networks architecture. With Software Defined Network (SDN) architecture, in this paper, we address edge controller placement as an optimization problem with the objective of more robustness while minimizing the delay of network management and the associated synchronization overhead. The optimization problem is provided and modelled as submodular function. Two algorithms are provided to find the optimal solution using a real wireless network to get more realistic results. Greedy Algorithm and Connectivity Ranking Algorithm are provided. Greedy algorithm outperforms connectivity ranking algorithm to find the optimum balance between the different metrics. Also, based on the network operator preference, the number of edge controllers to be placed will be provided. This research paper plays a great role in standardization of softwarization into Industrial communication systems for next generation wireless sensor networks.
A Consensus Model for Group Decision Making with Hesitant Fuzzy Information
Authors: Bukhari Syeda Mifzalah , Rehman Atiq-ur , Bibi Maria
Published: November 2022

This article presents a more improved consensus-based method for dealing with multi-person decision making (MPDM) that uses hesitant fuzzy preference relations (HFPRís) that arenít in the usual format. We proposed a Lukasiewicz transitivity (TL-transitivity)-based technique for establishing normalised hesitant fuzzy preference relations (NHFPRís) at the most essential level, after that, a model based on consensus is constructed. After that, a transitive closure formula is created in order to build TL -consistent hesitant fuzzy preference relations (HFPRís) and symmetrical matrices. Afterwards, a consistency analysis is performed to determine the degree of consistency of the data given by the decision makers (DMs), as a result, the consistency weights must be assigned to them. After combining consistency weights and preset(predeÖned) priority weights, the Önal priority weights vector of DMs is obtained (if there are any). The consensus process determines either data analysis and selection of a suitable alternative should be done directly or externally. The enhancement process aims to improve the DMís consensus measure, despite the implementation of an indicator for locating sluggish points, in the circumstance that an unfavorable agreement is achieved. Finally, a comparison case demonstrates the relevance and e§ectiveness of the proposed system. The conclusions indicate that the suggested strategy can provide insight into the MPDM system.

Predicting atmospheric background number concentration of ice-nucleating particles in the Arctic
Authors: Li Guangyu , Wieder Jörg , Pasquier Julie T. , Henneberger Jan , Kanji Zamin A.
Published: November 2022

Abstract. Mixed-phase clouds (MPCs) can have a net warming or cooling radiative effect on Earth's climate influenced by the phase and concentration of cloud particles. They have received considerable attention due to high spatial coverage and occurrence frequency in the Arctic. To initiate ice formation in MPCs at temperatures above −38 ∘C, ice-nucleating particles (INPs) are required, which therefore have important implications on the radiative properties of MPCs by altering the ice-to-liquid ratio of hydrometeors. As a result, constraining ambient INP concentrations could promote accurate representation of cloud microphysical processes and reduce the uncertainties in estimating the cloud-phase-related climate feedback in climate models. Currently, INP parameterizations are lacking for remote Arctic environments. Here we present INP number concentrations and their variability measured in Ny-Ålesund (Svalbard) at temperatures between 0 and −30 ∘C. No distinguishable seasonal difference was observed from 12 weeks of field measurements during October and November 2019 and March and April 2020. Compared to existing studies, the absence of a seasonal difference is not surprising, as most seasonal differences are reported for summer versus winter time INP concentrations. In addition, correlating INP concentrations to aerosol physical properties was not successful. Therefore, we propose a lognormal-distribution-based parameterization to predict Arctic INP concentration solely as a function of temperature, specifically for the transition seasons autumn and spring to fill in the data gap in the literature pertaining to these seasons. In practice, the parameterized variables allow for (i) the prediction of the most likely INP concentrations and (ii) the retrieval of the governing distribution of INP concentrations at given temperatures in the Arctic.
Technique for comparison of backscatter coefficients derived from in situ cloud probe measurements with concurrent airborne lidar
Authors: Wagner Shawn Wendell , Delene David James
Published: November 2022

Abstract. Jet engine power loss due to ice particle accumulation is a recognized
aviation hazard occurring in cloud conditions difficult to forecast or
visually recognize. High-altitude cirrus clouds can have ice particle
concentrations high enough to be dangerous; therefore, pilots must be
informed when aircraft enter such environments. One approach to determining
ice particle concentration is an onboard lidar system. Concurrent lidar
measurements are compared to backscatter coefficients derived from particle
size distributions obtained from wing-mounted, in situ probes during four
case studies consisting of sixty-second flight segments at different
temperatures: +7 and +4 ∘C for water droplet
analysis, and −33 and −46 ∘C for ice particle analysis.
Backscatter coefficients derived from external cloud probes (ECP) are
correlated (0.91) with measurements by an airborne lidar system known as the
Optical Ice Detector (OID). Differences between OID and ECP backscatter
coefficients range from less than 1 to over 3 standard deviations in terms of uncertainties. The backscatter coefficients are mostly in agreement for
liquid clouds and are in disagreement for the −33 and −46 ∘C cases, with ECP-derived backscatter coefficients lower than
the OID for three out of the four cases. Measurements over four 60 s research flight segments show that measured total water content is
correlated (0.74) with the OID backscatter coefficient, which indicates that
the OID is a useful instrument for determining ice particle concentrations
over a broad range of environments, including at ice water contents as low
as 0.02 g m−3. Additionally, concurrent measurements from cloud imaging
probes and the OID provide improved knowledge of cloud conditions, which may
help in understanding cloud processes.
Complementarity of wind measurements from co-located X-band weather radar and Doppler lidar

Published: November 2022

Abstract. Accurate wind profile measurements are important for applications ranging from aviation to numerical weather prediction. The spatial pattern of winds can be obtained with ground-based remote sensing instruments, such as weather radars and Doppler lidars. As the return signal in weather radars is mostly due to hydrometeors or insects, and in Doppler lidars due to aerosols, the instruments provide wind measurements in different weather conditions. However, the effect of various weather conditions on the measurement capabilities of these instruments has not been previously extensively quantified. Here we present results from a 7-month measurement campaign that took place in Vantaa, Finland, where a co-located Vaisala WRS400 X-band weather radar and WindCube 400S Doppler lidar were employed continuously to perform wind measurements. Both instruments measured plan position indicator (PPI) scans at 2.0∘ elevation from the horizontal. Direct comparison of radial Doppler velocities from both instruments showed good agreement with R2=0.96. We then examined the effect of horizontal visibility, cloud base height, and precipitation intensity on the measurement availability of each instrument. The Doppler lidar displayed good availability in clear air situations and the X-band radar in precipitation. Both instruments exhibited high availability in clear air conditions in summer when insects were present. The complementary performance in the measurement availability of the two instruments means that their combination substantially increases the spatial coverage of wind observations across a wide range of weather conditions.
Technical note: Modeling spatial fields of extreme precipitation – a hierarchical Bayesian approach
Authors: Rahill-Marier Bianca , Devineni Naresh , Lall Upmanu
Published: November 2022

Abstract. We introduce a hierarchical Bayesian model for the
spatial distribution of rainfall corresponding to an extreme event of a
specified duration that could be used with regional hydrologic models to
perform a regional hydrologic risk analysis. An extreme event is defined if
any gaging site in the watershed experiences an annual maximum rainfall
event and the spatial field of rainfall at all sites corresponding to that
occurrence is modeled. Applications to data from New York City demonstrate
the effectiveness of the model for providing spatial scenarios that could be
used for simulating loadings into the urban drainage system. Insights as to
the homogeneity in spatial rainfall and its implications for modeling are
provided by considering partial pooling in the hierarchical Bayesian
framework.

Memoria profunda: expresiones y trayectorias del sufrimiento social en Colombia
Authors: Gómez Correal Diana
Published: November 2022

La violencia sociopolítica en Colombia ha afectado la vida de las víctimas directas de la violencia y la de sus familiares, desencadenado sufrimiento social. Este sufrimiento se expresa en emociones, memoria y cuerpo configurando una memoria profunda. Esta es una memoria que acompaña a los familiares en su diario trasegar, se instala en el ser y es de difícil abordaje porque verbalizarla e identificarla es complejo y requiere de desplazamientos epistemológicos que problematicen el pensamiento dicotómico y el logocentrismo; y de desplazamientos políticos que pongan en el centro el bien-estar de los familiares. Este artículo aborda desde epistemologías feministas estos desplazamientos, la configuración de la memoria profunda y algunas de las particularidades que toma en las trayectorias de vida de familiares de víctimas de violencia sociopolítica, así como formas de lidiar con ella para hacer más liviano el trasegar de los familiares.

The aim of this study is to investigate the acute effects of different stretching methods on acceleration, vertical jump (CMJ), flexibility and upper extremity performance of young wrestlers. 8 young female wrestlers (15.37 ± 1.06 years; 162.46 ± 4.12 cm and 57.47 ± 6.41 kg) participated in the study voluntarily. Stretching methods were divided into five groups: control (no stretching), static, dynamic, static + dynamic and dynamic + static. The findings showed faster speed performance after control (p = .012; η2 = 0.57), dynamic stretching (p = .050; η2 = 1.11) and static + dynamic combined stretching (p = .043; η2 = 0.96) compared to static stretching; and there is a statistically significant positive difference according to the test averages after dynamic stretching (p = .050; η2 = 0.91) compared to dynamic + static combined stretching (p<0.05). Vertical jump performance, according to the control warming up, a statistically significant difference has been found according to the test averages after dynamic stretching (p = 041; η2 = 1.17) and static + dynamic combined stretching (p = .043; η2 = 1.07). No difference was found in flexibility and medicine ball throwing performances according to different stretching protocols (p>0.05). . It was determined that the acute effect of static stretching had a negative effect on acceleration performances and dynamic stretching caused an increase in jump performance. This study suggests that dynamic and static + dynamic stretching can be used in young wrestlers to provide better performance in acceleration and jumping skills during warm-up sessions.

The purpose of the present study was to investigate the influence of 12-week artistic gymnastics training on children's strength and static balance performance. A total of 32 children attending gymnastic club for kids with mean age 6.09 ± 7.45 years; height 106.81 ± 5.47 cm, body weight 17.00 ± 2.72kg and body mass index (BMI) 14.98 ± 2.57 kg/m2 were included in the study. A training program with 270-minute intensity at a frequency of 3 days a week for 12 weeks has been implemented for all participants. Hand grip strength test, stretched arm hanging duration on high bar and stork balance test for dominant and non-dominant legs were applied to the participants. SPSS 21.0 statistical program was used in the statistical analysis of the data and the statistical significance level was accepted as <0.05. As a result of the study, while a statistically significant difference has not been observed between Non-dominant leg stork balance pre-test and the post-test (p=0.06>0.05), a statistically significant difference was observed between the Dominant leg stork balance pre-test and the post-test (p=0.00<0.05). However, a significant difference was found between both hand grip strength pre-test and post-test (p=0.00<0.05) and stretched arm hanging duration on high bar pre-test and post-test (p=0.00<0.05). There was a statistically significant difference between the participant’s pretest sit and reach and the post-test (p= 0.00<0.05). It can be said with this study that 12-week artistic gymnastics training increased children's forearm flexor muscle isometric strength and balance performance.

Background/Aims: Exacerbating factors of ulcerative colitis (UC) are multiple and complex with individual influence. We aimed to evaluate the efficacy of disease control by searching and restricting inflammation trigger factors of UC relapse individually in daily clinical practice. Methods: Both patients with UC history or new diagnosis were asked to avoid dairy products at first doctor visit. Individual-reported potential trigger factors were restricted when UC flared up (Mayo endoscopy score ≥1) from remission status. The remission rate, duration to remission and medication were analyzed between the groups of factor restriction complete, incomplete and unknown. Results: The total remission rate was 91.7% of 108 patients with complete restriction of dairy product. The duration to remission of UC history group was significantly longer than that of new diagnosis group (88.5 days vs. 43.4 days, P=0.006) in patients with initial endoscopic score 2–3, but no difference in patients with score 1. After first remission, the inflammation trigger factors in 161 relapse episodes of 72 patients were multiple and personal. Milk/dairy products, herb medicine/Chinese tonic food and dietary supplement were the common factors, followed by psychological issues, non-dietary factors (smoking cessation, cosmetic products) and discontinuation of medication by patients themselves. Factor unknown accounted for 14.1% of patients. The benefits of factor complete restriction included shorter duration to remission (P<0.001), less steroid and biological agent use (P=0.022) when compared to incomplete restriction or factor unknown group. Conclusions: Restriction of dairy diet first then searching and restricting trigger factors personally if UC relapse can improve the disease control and downgrade the medication usage of UC patients in daily clinical practice.
Optimization of Content Based Image Retrieval Using Hybrid Approach

With the dawn of multimedia technology and the social web, retrieval from large image databases become possible. As a consequence of rising usage and incredible enthusiasm for inquiry about on Content-Based Image Retrieval (CBIR) systems, it needs improvement in the accuracy of CBIR systems in addition to the decline in monotonous
results. Currently, the majority of research has focused on the representation and differentiation of images by an arrangement of low-level visual features. However, most of the retrieval systems produce repetitive or unnecessary retrieval results, termed a redundancy factor. In addition, content-based retrieval with reduced redundancy has a
direct correlation with high-level semantics which is overlooked. Accurate content retrieval with reduced redundancy enables the user to focus on the actual problem in preference to nurture the retrieval results, augments the efficiency, and improves overall system performance. To enhance the retrieval accuracy and diminish the redundancy factor in image retrieval, we proposed an optimization-based technique that is blended with classification. In the proposed novel hybrid approach for CBIR, we used a two-tier architecture model. The first tier belongs to the feature extraction process via Particle Swarm Optimization with a Support Vector Machine as a classifier. On the way to reduce the redundancy factor, the K-Nearest Neighbor as a classifier is used with the Genetic Algorithm in the second tier. We noted a noteworthy increase in retrieval accuracy for images that is up to 25% (approx.). The proposed hybrid model is effective to enhance accuracy and reduce redundancy factors in CBIR systems. We used the WANG dataset for experimentation. Henceforward, improving the retrieval accuracy and reducing redundancy factor using unsupervised learning techniques is part of our future work.
Scandinavian Studies in ­Rhetoric. Rhetorica Scandinavica 1997-2010
Authors: Kjeldsen Jens E. , Grue Jan
Published: November 2022

Rhetorica Scan­di­navica has functioned as a sower of academic seeds. As the journal has grown, rhetoric courses and programmes have multiplied across Scandinavia. The journal is the major source of native-language literature in the field, and ­articles frequently find a place on ­curricula. Thus, Rhetorica Scan­di­navica has had a significant impact on the study of rhetoric in the Scandi­navian countries. The 18 articles in this book are just a few highlights from 13 years – a total of over 225 peer-reviewed articles – of Rhetorica Scan­di­navica publications. They have been chosen to introduce some aspects of the study of rhetoric as it is performed in Scandinavia to a readership that is un­familiar with the three Scandinavian ­languages
Den nakna sanningen

In the summer of 1932, Dagbräckning [Daybreak], the first Swedish nudist journal, was founded with the mission of getting people to sunbathe, swim and do gymnastics naked. It was soon followed by Natur och Hälsa [Nature and Health] and Solvännen [Sun Friend], which alongside Dagbräckning sparkled interest in the emerging Swedish nudist movement. A recurring feature in these journals were conversion narratives in which men and women described how they became nudists. This article analyzes thirty-six conversion narratives from the 1930s and 1940s and demonstrates how a narrative structure drawn from a religious context helped nudists to make sense of their new identity and convince others of the possibilities of nudism. Using Ernest G. Bormann’s concept of rhetorical vision and his symbolic convergence theory as an interpretive framework, the article shows that in this religiously inispired way the nudists weaved together their experiences into a more encompassing drama about the freedom that awaited those who chose to practice nudism: freedom from clothing that obstructed natural movements, freedom from prejudice that limited individual thinking and freedom from rules that restricted social contacts
Hinder och frihet

The analysis of 45 written reflections on the rhetorical working process from a postgraduate course in research communication reveals the postgraduate students to reflect on actio and pronuntiatio in standardised ways and to a lesser extent than on the other canons. This applies both to the physical and the digital iterations of the course. The students often link actio and pronuntiatio to elocutio and memoria and view oral presentations from a speaker-centered rather than audience-centered perspective. Not surprisingly, the students note that their body language becomes limited in the digital classroom and that they, therefore, must utilise their voices more. Depending on the students’ understanding of actio and pronuntiatio, utilising these can become a barrier or a breakthrough for successful research communication. These results prompt further discussion of actio’s and pronuntiatio’s potential for teaching research communication in the physical and the digital spaces
