Crossing the Linguistic Causeway: Ethnonational Differences on Soundscape Attributes in Bahasa Melayu

Despite being neighbouring countries and sharing the language of Bahasa Melayu (ISO 639-3:ZSM), cultural and language education policy differences between Singapore and Malaysia led to differences in the translation of the "annoying" perceived affective quality (PAQ) attribute from English (ISO 639-3:ENG) to ZSM. This study expands upon the translation of the PAQ attributes from eng to ZSM in Stage 1 of the Soundscapes Attributes Translation Project (SATP) initiative, and presents the findings of Stage 2 listening tests that investigated ethnonational differences in the translated ZSM PAQ attributes and explored their circumplexity. A cross-cultural listening test was conducted with 100 ZSM speakers from Malaysia and Singapore using the common SATP protocol. The analysis revealed that Malaysian participants from non-native ethnicities (my:o) showed PAQ perceptions more similar to Singapore (sg) participants than native ethnic Malays (MY:M) in Malaysia. Differences between Singapore and Malaysian groups were primarily observed in stimuli related to water features, reflecting cultural and geographical variations. Besides variations in water source-dominant stimuli perception, disparities between MY:M and SG could be mainly attributed to vibrant scores. The findings also suggest that the adoption of region-specific translations, such as membingitkan in Singapore and menjengkelkan in Malaysia, adequately addressed differences in the annoying attribute, as significant differences were observed in one or fewer stimuli across ethnonational groups The circumplexity analysis indicated that the quasi-circumplex model better fit the data compared to the assumed equal angle quasi-circumplex model in ISO/TS 12913-3, although deviations were observed possibly due to respondents' unfamiliarity with the United Kingdom-centric context of the stimulus dataset...Comment: Preprint submitted to Elsevier for revie

Soundscape assessment : towards a validated translation of perceptual attributes in different languages

The recently published ISO/TS 12913-2:2018 standard aims to provide researchers and practitioners around the world with a reliable questionnaire for soundscape characterization. The ISO Technical Specifications report protocols and attributes grounded in the soundscape literature, but only includes an English version. The applicability and reliability of these attributes in non-English speaking regions remains an open question, as research investigating translations of soundscape attributes is limited. To address this gap, an international collaboration was initiated with soundscape researchers from all over the world. Translation into 15 different languages, obtained through focus groups and panels of experts in soundscape studies, are proposed. The main challenges and outcomes of this preliminary exercise are discussed. The long-term objective is to validate the proposed translations using standardized listening experiments in different languages and geographical regions as a way to promote a widespread use of the soundscape attributes, both in academia and practice, across locations, populations and languages

Effects of hospital facilities on patient outcomes after cancer surgery: an international, prospective, observational study

Background Early death after cancer surgery is higher in low-income and middle-income countries (LMICs) compared with in high-income countries, yet the impact of facility characteristics on early postoperative outcomes is unknown. The aim of this study was to examine the association between hospital infrastructure, resource availability, and processes on early outcomes after cancer surgery worldwide.Methods A multimethods analysis was performed as part of the GlobalSurg 3 study-a multicentre, international, prospective cohort study of patients who had surgery for breast, colorectal, or gastric cancer. The primary outcomes were 30-day mortality and 30-day major complication rates. Potentially beneficial hospital facilities were identified by variable selection to select those associated with 30-day mortality. Adjusted outcomes were determined using generalised estimating equations to account for patient characteristics and country-income group, with population stratification by hospital.Findings Between April 1, 2018, and April 23, 2019, facility-level data were collected for 9685 patients across 238 hospitals in 66 countries (91 hospitals in 20 high-income countries; 57 hospitals in 19 upper-middle-income countries; and 90 hospitals in 27 low-income to lower-middle-income countries). The availability of five hospital facilities was inversely associated with mortality: ultrasound, CT scanner, critical care unit, opioid analgesia, and oncologist. After adjustment for case-mix and country income group, hospitals with three or fewer of these facilities (62 hospitals, 1294 patients) had higher mortality compared with those with four or five (adjusted odds ratio [OR] 3.85 [95% CI 2.58-5.75]; p<0.0001), with excess mortality predominantly explained by a limited capacity to rescue following the development of major complications (63.0% vs 82.7%; OR 0.35 [0.23-0.53]; p<0.0001). Across LMICs, improvements in hospital facilities would prevent one to three deaths for every 100 patients undergoing surgery for cancer.Interpretation Hospitals with higher levels of infrastructure and resources have better outcomes after cancer surgery, independent of country income. Without urgent strengthening of hospital infrastructure and resources, the reductions in cancer-associated mortality associated with improved access will not be realised

Traditional musical instruments in present musical life of Lebu' Kulit in Sungai Asap, Sarawak

The Lebu’ Kulit people refer to themselves as belonging to one of the different subgroups of Kenyah. In the past, they migrated from Usun Apau and settled in few places on Borneo Island. The community is now separated and dispersed in different locations in Sarawak, Malaysia and East Kalimantan, Indonesia. At present, there is only one Lebu’ Kulit village in Sarawak. Since the year 1999, they have been staying in Sungai Asap in the Belaga District of Kapit Division. Along the stream of migrations and historical happenings which can be traced back to the early twentieth century, the Lebu’ Kulit people in Sungai Asap experienced a series of events such as headhunting, Dutch governance in Kalimantan, conversion to Christianity, the formation of Malaysia, the Confrontation War in the year 1963, and resettlement to Sungai Asap by the Sarawak government due to the construction of Bakun dam. As there is a lack of information on the musical culture of the Lebu’ Kulit in Sungai Asap, this is the first study that intends to document and analyse their present musical life and the culture of the community particularly on their traditional musical instruments. Several fieldtrips were made to the village from December 2009 to July 2011, and data on music practices as well as their cultural background were collected through audiovisual recordings, interviews, interactions, and participant-observations in their activities. Analyses and reflections were derived via study of audiovisual recordings,music transcriptions, and information obtained from interviews and observations. The traditional musical instruments in the present musical life of the Lebu’Kulit in Sungai Asap includes udang kadung (xylophone), sampé’ daru’ (zither),sampé’ bup (lute), sampé’ ja’au (lute), selingut (transverse flute), kediré’ alo’ (mouth organ), and wing or iceh (vessel rattle). These instruments are playedmostly in heterogeneous ensemble to accompany dance, songs or as instrumental music entertainment. The tuning of these musical instruments is similar to the western diatonic major scale. The musicians’ common repertoire consists of the traditional Kenyah tune Det Diet, the local folksongLenggang Kangkung, various Christian hymns and Gurkha songs. The performing style of a tune is usually repetitive with variations in rhythmic structures, registers, embellishments and dynamic accents. The playing of traditional musical instruments of the Lebu’ Kulit is significantly influenced by their beliefs especially through changes in their religion, historical events, present social and economic context, and individual self-expression. It seems that the traditional instrumental music of the Lebu’ Kulit has been “restarted” in a new form and meaning around sixty years ago and has become “singularised”. Besides, the frequency of traditional musical instruments playing has reduced to functions and festive seasons. The repertoire in the traditional musical sphere consists mostly of imported materials, and of which are adopted and internalised, and areexpressed in their own creativity and skills

Narrative review of soundscape studies

Soundscape generally refers to the sonic environment. The study of soundscape is significant to improve the quality of the environment, enhance the function of a place and promote a healthy and quality life as well as for the understanding of cultures. Given approximately half a century of scholarly studies on soundscape, the purpose of this conceptual paper is to present a narrative review of the literature on its definitions, methods, fields and space types from various disciplines to provide an overview and reference to novice soundscape researchers. As it is a wide-ranging field, soundscape study inherently encompasses research from multiple disciplines and mostly necessitates cross-disciplinary approaches. Among the diversity with different emphases on research frameworks and methodologies, soundscape research usually incorporates the three elements of acoustic properties, perception and place. The study can be for documentation, description, management and/or creation of soundscape. Some of the fields of soundscape study involve acoustic ecology, acoustemology, ecomusicology, acoustic engineering, artistic creativity or wellbeing. Data were usually collected through audio recordings, measurements of sound levels, soundwalks, questionnaires and interviews. Soundscape research has been increasing in America and European countries and can potentially be further expanded on different distinctive sound environments, ecosystems and sociocultural lifestyles

Crossing the linguistic causeway: a binational approach for translating soundscape attributes to Bahasa Melayu

Translation of perceptual descriptors such as the perceived affective quality attributes in the soundscape standard (ISO/TS 12913–2:2018) is an inherently intricate task, especially if the target language is used in multiple countries. Despite geographical proximity and a shared language of Bahasa Melayu (Standard Malay), differences in culture and language education policies between Singapore and Malaysia could invoke peculiarities in the affective appraisal of sounds. To generate provisional translations of the eight perceived affective attributes — eventful, vibrant, pleasant, calm, uneventful, monotonous, annoying, and chaotic — into Bahasa Melayu that is applicable in both Singapore and Malaysia, a binational expert-led approach supplemented by a quantitative evaluation framework was adopted. A set of preliminary translation candidates were developed via a four-stage process, firstly by a qualified translator, which was then vetted by linguistics experts, followed by examination via an experiential evaluation, and finally reviewed by the core research team. A total of 66 participants were then recruited cross-nationally to quantitatively evaluate the preliminary translation candidates. Of the eight attributes, cross-national differences were observed only in the translation of annoying. For instance, menjengkelkan was found to be significantly less understood in Singapore than in Malaysia, as well as less understandable than membingitkan within Singapore. Results of the quantitative evaluation also revealed the imperfect nature of foreign language translations for perceptual descriptors, which suggests a possibility for exploring corrective measures

Global variation in postoperative mortality and complications after cancer surgery: a multicentre, prospective cohort study in 82 countries

Background: 80% of individuals with cancer will require a surgical procedure, yet little comparative data exist on early outcomes in low-income and middle-income countries (LMICs). We compared postoperative outcomes in breast, colorectal, and gastric cancer surgery in hospitals worldwide, focusing on the effect of disease stage and complications on postoperative mortality. Methods: This was a multicentre, international prospective cohort study of consecutive adult patients undergoing surgery for primary breast, colorectal, or gastric cancer requiring a skin incision done under general or neuraxial anaesthesia. The primary outcome was death or major complication within 30 days of surgery. Multilevel logistic regression determined relationships within three-level nested models of patients within hospitals and countries. Hospital-level infrastructure effects were explored with three-way mediation analyses. This study was registered with ClinicalTrials.gov, NCT03471494. Findings: Between April 1, 2018, and Jan 31, 2019, we enrolled 15 958 patients from 428 hospitals in 82 countries (high income 9106 patients, 31 countries; upper-middle income 2721 patients, 23 countries; or lower-middle income 4131 patients, 28 countries). Patients in LMICs presented with more advanced disease compared with patients in high-income countries. 30-day mortality was higher for gastric cancer in low-income or lower-middle-income countries (adjusted odds ratio 3·72, 95% CI 1·70–8·16) and for colorectal cancer in low-income or lower-middle-income countries (4·59, 2·39–8·80) and upper-middle-income countries (2·06, 1·11–3·83). No difference in 30-day mortality was seen in breast cancer. The proportion of patients who died after a major complication was greatest in low-income or lower-middle-income countries (6·15, 3·26–11·59) and upper-middle-income countries (3·89, 2·08–7·29). Postoperative death after complications was partly explained by patient factors (60%) and partly by hospital or country (40%). The absence of consistently available postoperative care facilities was associated with seven to 10 more deaths per 100 major complications in LMICs. Cancer stage alone explained little of the early variation in mortality or postoperative complications. Interpretation: Higher levels of mortality after cancer surgery in LMICs was not fully explained by later presentation of disease. The capacity to rescue patients from surgical complications is a tangible opportunity for meaningful intervention. Early death after cancer surgery might be reduced by policies focusing on strengthening perioperative care systems to detect and intervene in common complications.

Soundscape Attributes Translation Project (SATP) Dataset

The data and audio included here were collected for the Soundscape Attributes Translation Project (SATP). First introduced in Aletta et. al. (2020), the SATP is an attempt to provide validated translations of soundscape attributes in languages other than English. The recordings were used for headphones - based listening experiments. The data are provided to accompany publications resulting from this project and to provide a unique dataset of 1000s of perceptual responses to a standardised set of urban soundscape recordings. This dataset is the result of efforts from hundreds of researchers, students, assistants, PIs, and participants from institutions around the world. We have made an attempt to list every contributor to this Zenodo repo; if you feel you should be included, please get in touch. Citation: If you use the SATP dataset or part of it, please cite our paper describing the data collection and this dataset itself. Overview: The SATP dataset consists of 27 30-sec binaural audio recordings made in urban public spaces in London and one 60 sec stereo calibration signal. The recordings were made at locations as reported in Table 1 of the README.md (Recording locations), at various times of day by an operator wearing a binaural kit consisting of BHS II microphones and a SQobold (HEAD acoustics) device. Recordings were then exported to WAV via the ArtemiS SUITE software, using the original dynamic range from HDF. The listening experiment and the calibration procedure were intended for a headphone playback system (Sennheiser HD650 or similar open-back headphones recommended).  The recordings were selected from an initial set of 80 recordings through a pilot study to ensure the test set had an even coverage of the soundscape circumplex space. These recordings were sent to the partner institutions (see Table 2 of the README.md) and assessed by approximately 30 participants in the institution's target language. The questionnaire used in each assessment is a translation of Method A Questionnaire, ISO 12913-2:2018. Each institution carried out their own lab experiment to collect data, then submitted their data to the team at UCL to compile into a single dataset. Some institutions included additional questions or translation options; the combined dataset (`SATP Dataset v1.x.xlsx`) includes only the base set of questions, the extended set of questions from each institution is included in the `Institution Datasets` folder. In all, SATP Dataset v1.2 contains 17,441 samples, including 645 participants, for 27 recordings, in 19 languages with contributions from 29 institutions. Format: The audio recordings are provided as 24 bit, 48 kHz, stereo WAV files. The combined dataset and Institutional datasets are provided as long tidy data tables in .xlsx files. Calibration: The recommended calibration approach was based on the open-circuit voltage (OCV) procedure which was considered most accessible but other calibration procedures are also possible (Lam et. al. (2022)). The provided calibration file is a computer generated sine wave at 1kHz, matching a sine wave recorded using the exact same setup at SPL of 94 dB. In case of the calibration signal playback level set to match SPL of 94 dB at the eardrum, all the 27 samples should be reproduced at realistic loudness. More details on OCV calibration procedure and other options you can find in Lam et. al. (2022) and the attached documentation. PLEASE DO NOT EXPOSE YOURSELF NOR THE PARTICIPANTS TO THE CALIBRATION SIGNAL SET AT THE REALISTIC LEVEL AS IT CAN CAUSE HARM. License and reuse: All SATP recordings are provided under the Creative Commons Attribution 4.0 International (CC BY 4.0) License and are free to use. We encourage other researchers to replicate the SATP protocol and contribute new languages to the dataset. We also encourage the use of these recordings and the perceptual data for further soundscape research purposes. Please provide the proper attribution and get in touch with the authors if you would like to contribute a new translation or for any other collaborations
