Internal tree cycling and atmospheric archiving of mercury: examination with concentration and stable isotope analyses
Authors: McLagan David S. , Biester Harald , Navrátil Tomas , Kraemer Stephan M. , Schwab Lorenz
Published: September 2022

Abstract. Trees predominantly take up mercury (Hg) from the
atmosphere via stomatal assimilation of gaseous elemental Hg (GEM). Hg is
oxidised in leaves/needles and transported to other tree anatomy including
bole wood, where it can be stored long-term. Using Hg associated with growth
rings facilitates archiving of historical GEM concentrations. Nonetheless,
there are significant knowledge gaps on the cycling of Hg within trees. We
investigate Hg archived in tree rings, internal tree Hg cycling, and
differences in Hg uptake mechanisms in Norway spruce and European larch
sampled within 1 km of a HgCl2-contaminated site using total Hg (THg)
and Hg stable isotope analyses. Tree ring samples are indicative of
significant increases in THg concentrations (up to 521 µg kg−1) from the background period (BGP; facility closed; 1992–present) to secondary industrial period (2ndIP; no HgCl2 wood treatment; 1962–1992) to primary industrial period (1stIP; active HgCl2 wood
treatment; ≈ 1900–1962). Mass-dependent fractionation (MDF) Hg
stable isotope data are shifted negative during industrial periods (δ202Hg of 1stIP: −4.32 ± 0.15 ‰,
2ndIP: −4.04 ± 0.32 ‰, BGP: −2.83 ± 0.74 ‰; 1 SD). Even accounting for a ≈ −2.6 ‰ MDF shift associated with stomatal uptake,
these data are indicative of emissions derived from industrial activity
being enriched in lighter isotopes associated with HgCl2 reduction and
Hg0 volatilisation. Similar MDF (δ202Hg: −3.90 ± 0.30 ‰; 1 SD) in bark Hg (137 ± 105 µg kg−1) suggests that stomatal assimilation and downward
transport is also the dominant uptake mechanism for bark Hg (reflective of
negative stomatal-uptake MDF shift) rather than deposition to bark. THg was
enriched in sapwood of all sampled trees across both tree species. This may
indicate long-term storage of a fraction of Hg in sapwood or xylem solution. We also observed a small range of odd-isotope mass-independent fractionation (MIF). Differences in Δ199Hg between periods of different industrial activities were
significant (Δ199Hg of 1stIP: 0.00 ± 0.03 ‰, 2ndIP: −0.06 ± 0.04 ‰, BGP: −0.13 ± 0.03 ‰; 1 SD), and we suggest MIF
signatures are conserved during stomatal assimilation (reflect source MIF
signatures). These data advance our understanding of the physiological
processing of Hg within trees and provide critical direction to future
research into the use of trees as archives for historical atmospheric Hg.
Shallow marine carbonates as recorders of orbitally induced past climate changes – example from the Oxfordian of the Swiss Jura Mountains
Authors: Strasser André
Published: September 2022

Abstract. Today and in the geologic past, climate changes greatly affect and have affected Earth surface processes. While the climatic parameters today can be measured with high precision, they have to be interpreted from the sedimentary record for ancient times. This review is based on the detailed analysis of stratigraphic sections of Oxfordian (Late Jurassic) age, with the aim to reconstruct and discuss the climate changes that controlled the sedimentation on the shallow marine carbonate platform that today is represented in the Swiss Jura Mountains. The sediments formed under subtropical conditions in which carbonate-producing organisms proliferated, and ooids and oncoids were common. The sections are composed of hierarchically stacked elementary, small-scale, and medium-scale depositional sequences wherein facies changes imply deepening–shallowing trends. The major sequence boundaries Ox 6, Ox 7, and Ox 8 can be correlated with those of other European basins and place the studied sections in a broader framework. The chronostratigraphic tie points imply that the medium- and small-scale sequences formed in tune with the orbital eccentricity cycles of 405 and 100 kyr, respectively, and the elementary sequences with the precession cycle of 20 kyr. Orbitally controlled insolation changes at the top of the atmosphere translated into climate changes: low insolation generally resulted in low amplitudes of sea level fluctuations at the 20 kyr frequency and in a cool and humid climate at the palaeolatitude of the Jura platform. Terrigenous material was eroded from the hinterland and distributed over the platform. High insolation led to sea level rise, as well as to warm and semiarid to arid conditions in which coral reefs could grow. However, nutrient input favoured growth of microbialites that encrusted the corals. The reconstruction of high-frequency sea level fluctuations based on facies analysis compares well with the curve of insolation changes calculated for the past 550 kyr. It is therefore assumed that the sea level fluctuations were mainly due to thermal expansion and retraction of ocean surface water. Two models are presented that explain the formation of elementary sequences: one for low and one for high insolation. Despite the important lateral facies variations typical of a shallow marine platform, and despite the uncertainties in the reconstruction of sea level changes, this study demonstrates the potential of carbonate ecosystems to record past climate changes at a time resolution of 20 000 years. Relatively short time windows can thus be opened in the deep geologic past, and processes and products there can be compared with those of the Holocene and the Anthropocene. For example, it appears that today's anthropogenically induced sea level rise is more than 10 times faster than the fastest rise reconstructed for the Oxfordian.
Characterizing basin-scale precipitation gradients in the Third Pole region using a high-resolution atmospheric simulation-based dataset

Published: September 2022

Abstract. Altitudinal precipitation gradient plays an important role in the
interpolation of precipitation in the Third Pole (TP) region, where the
topography is very complex but in situ data are very sparse. This study proves that the altitude dependence of precipitation in the TP can be
reasonably reproduced by a high-resolution atmospheric simulation-based
dataset called ERA5_CNN. The precipitation gradients,
including both absolute (APGs) and relative gradients (RPGs), for 388 sub-basins of the TP above 2500 m a.s.l. are calculated based on the
ERA5_CNN. Results show that most sub-basins have positive
precipitation gradients, and negative gradients are mainly found along the
Himalayas, the Hengduan Mountains and the western Kunlun. The annual APG and RPG averaged across all sub-basins of the TP are 0.05 mm d−1 × 100 m−1 and 4.25 % × 100 m−1, respectively. The values of the APG are large in wet seasons but small in dry seasons, while the RPG shows opposite
variations. Further analyses demonstrate that the RPGs have negative
correlations with relative humidity but positive correlations with wind
speed, likely because dry air tends to reach saturation at high altitudes,
while stronger wind can bring more humid air to high altitudes. In addition,
we find that precipitation gradients tend to be positive at small spatial
scales compared to those at large scales, mainly because local topography
plays a vital role in determining precipitation distribution at small
scales. These findings on the spatiotemporal variations of precipitation
gradients provide useful information for interpolating precipitation in the
TP region.
An update on dissolved methane distribution in the subtropical North Atlantic Ocean
Authors: Kolomijeca Anna , Marx Lukas , Reynolds Sarah , Cariou Thierry , Mawji Edward , Boulart Cedric
Published: September 2022

Abstract. Methane (CH4) is a potent greenhouse gas and plays a
significant role in recent increasing global temperatures. The oceans are a
natural source of methane contributing to atmospheric methane
concentrations, yet our understanding of the oceanic methane cycle is poorly
constrained. Accumulating evidence indicates that a significant part of
oceanic CH4 is produced in oxygenated surface waters as a by-product of
phytoplanktonic activity. This study focused on the subtropical North
Atlantic Ocean (26∘ N, 80′ W and 26∘ N, 18′ W) where the distribution of
dissolved CH4 concentrations and associated air–sea fluxes during
winter 2020 were investigated. Water samples from 64 stations were collected
from the upper water column up to depths of 400 m. The upper oxic
mixed layer was oversaturated in dissolved CH4 with concentrations
ranging 3–7 nmol L−1, with the highest concentrations of 7–10 nmol L−1
found to the east of the transect, consistent with other subtropical regions
of the world's oceans. The high anomalies of dissolved CH4 were found
to be associated with phosphate-depleted waters and regions where the
abundance of the ubiquitous picocyanobacteria Synechococcus and Prochlorococcus were elevated. Although
other phytoplanktonic phyla cannot be excluded, this suggests that
cyanobacteria contribute to the release of CH4 in this region. The
calculation of air–sea fluxes further confirmed the subtropical North
Atlantic Ocean as a source of CH4. This study provides evidence to
corroborate the key role that picocyanobacteria play in helping to explain
the oversaturation of CH4 found in surface mixed layer of the open
ocean, otherwise known as the “ocean methane paradox”.
A new Level 4 multi-sensor ice surface temperature product for the Greenland Ice Sheet

Published: September 2022

Abstract. The Greenland Ice Sheet (GIS) is subject to amplified impacts of climate change and its monitoring is essential for understanding and improving
scenarios of future climate conditions. Surface temperature over the GIS is an important variable, regulating processes related to the exchange of
energy and water between the surface and the atmosphere. Few local observation sites exist; thus spaceborne platforms carrying thermal infrared
instruments offer an alternative for surface temperature observations and are the basis for deriving ice surface temperature (IST) products. In this study several satellite IST products for the GIS were compared, and the first multi-sensor, gap-free (Level 4, L4) product was developed and
validated for 2012. High-resolution Level 2 (L2) products from the European Space Agency (ESA) Land Surface Temperature Climate Change Initiative
(LST_cci) project and the Arctic and Antarctic Ice Surface Temperatures from Thermal Infrared Satellite Sensors (AASTI) dataset were assessed
using observations from the PROMICE (Programme for Monitoring of the Greenland Ice Sheet) stations and IceBridge flight campaigns. AASTI showed overall better performance compared to LST_cci data,
which had superior spatial coverage and availability. Both datasets were utilised to construct a daily, gap-free L4 IST product using the optimal
interpolation (OI) method. The resulting product performed satisfactorily when compared to surface temperature observations from PROMICE and
IceBridge. Combining the advantages of satellite datasets, the L4 product allowed for the analysis of IST over the GIS during 2012, when a
significant melt event occurred. Mean summer (June–August) IST was −5.5 ± 4.5 ∘C, with an annual mean of
−22.1 ± 5.4 ∘C. Mean IST during the melt season (May–August) ranged from −15 to
−1 ∘C, while almost the entire GIS experienced at least between 1 and 5 melt days when temperatures were −1 ∘C
or higher. Finally, this study assessed the potential for using the satellite L4 IST product to improve model simulations of the GIS surface mass balance
(SMB). The L4 IST product was assimilated into an SMB model of snow and firn processes during 2012, when extreme melting occurred, to assess the
impact of including a high-resolution IST product on the SMB model. Compared with independent observations from PROMICE and IceBridge, inclusion of
the L4 IST dataset improved the SMB model simulated IST during the key onset of the melt season, where model biases are typically large and can
impact the amount of simulated melt.

Abstract. Here, we present a compilation of 85 ice temperature profiles from 79 boreholes from the Greenland Ice Sheet and peripheral ice caps, as well as local ice caps in the Canadian Arctic. Only 25 profiles (32 %) were previously available in open-access data repositories. The remaining 54 profiles (68 %) are being made digitally available here for the first time. These newly available profiles, which are associated with pre-2010 boreholes, have been submitted by community members or digitized from published graphics and/or data tables. All 85 profiles are now made available in both absolute (meters) and normalized (0 to 1 ice thickness) depth scales, and are accompanied by extensive metadata. This metadata includes a transparent description of data provenance. The ice temperature profiles span 70 years, with the earliest profile being from 1950 at Camp VI, West Greenland. To highlight the value of this database in evaluating ice flow simulations, we compare the ice temperature profiles from the Greenland Ice Sheet with an ice flow simulation by the Parallel Ice Sheet Model (PISM). We find a cold bias in modeled near-surface ice temperatures within the ablation area, a warm bias in modeled basal ice temperatures at inland cold-bedded sites, and an apparent underestimation of deformational heating in high-strain settings. These biases provide process-level insight on simulated ice temperatures.

Designing a Corncob Coffee Table By Utilizing the Physical Characteristics of Corncobs
Authors: Nuriafadsa Ramdini Zahra , Masri Andry
Published: September 2022

This research is about coffee table product design with corncob material that compromises the value of novelty offered with production factors in order to obtain real cost as a basis for considering the selling price. The coffee table production process is designed using the laminate technique. The processing technique chosen is the bending technique. This research was conducted at Craftindo Kreasi Bandung, precisely located in JI. Ciliwung canal no. 10, and is a continuation of research activities in the 2021 kedaireka matching fund platform program. In the previous study, a coffee table was produced with corncob material but did not use the bending technique. This design is based on opportunities based on previous research, namely (1) the industry has produced various kinds of commodities, but no one has ever tried to make coffee table products. (2) Sources of corn cob material can be obtained in various areas of West Java and can be available every 4 months. (3) In previous research, a coffee table with corncob material has been produced which needs to be developed by taking advantage of the opportunities for corncob characteristics that have been studied in material studies in previous studies, namely the comparative technique. The method used in this design is design iteration. At the end of the research, the output is in the form of a coffee table product prototype with a bending technique. The novelty of this research is the use of corn cobs as the main material and the use of bending techniques during production

Published: September 2022

The ongoing danger of ransomware has led to a struggle between creating and identifying novel approaches. Although detection and mitigation systems have been created and are used widely, they are always evolving and being updated due to their reactive nature. This is because harmful code and its behavior can frequently be altered to evade detection methods. In this study, we present a classification method that combines static and dynamic data to improve the precision of locky ransomware detection and classification. We trained supervised machine learning algorithms using cross-validation and used a confusion matrix to observe accuracy, enabling a systematic comparison of each algorithm. In this work, supervised algorithms such as the decision tree algorithm resulted in an accuracy of 97%, naïve baiyes  95%, random tree 63%, and ZeorR 50%.

The Bongo-dong Battle(鳳梧洞戰鬪) in 『Utsunomiya Taro Diary』
Authors:   The Paek-San Society, Yi Sanghun
Published: September 2022

The Bongo-dong Battle(鳳梧洞戰鬪) in 1920 is one of the most important battles in the War of Independence. Compared to its interest and importance, Bongo-dong Battle still lacks research. In particular, military criminal records and the scale of participation are still controversial. The situation of the Bongo-dong Battle was examined through 『Utsunomiya Taro Diary』 left by Utsunomiya Taro, the commander of the Joseon Army at the time. First, I checked the existence of the Japanese military support unit through 「Hong Beom-do Diary」. The process of Japanese troops' retreat can also be confirmed through 『Utsunomiya Taro Diary』. Second, it is presumed that the Japanese reinforcements were military police(憲兵) or police. Through 『Utsunomiya Taro Diary』, it is understood that the Japanese military's "increase squad" existed in addition to the pursuit team(追擊 隊) of Yasukawa Major(安川少佐). Third, the question of the credibility of 「Bongo-dong Battle Report(鳳梧洞附近戰鬪詳報)」 was dealt with. Through 『Utsunomiya Taro Diary』, it is possible to guess the situation in which the Japanese army was disadvantageous in the Bongo-dong Battle. Regarding the Bongo-dong battle, the Korean data and Japanese data should be cross-verified. In this context, interest in and discovery of Japanese data, including 「Bongo-dong Battle Report」 and 『Utsunomiya Taro Diary』, should continue.
Synthesis, NMR Study and Antioxidant potency of 3,5-dimethyl-2,6-bis(2,4-dichlorophenyl) piperidin-4-one
Authors: Dineshkumar J. , Parthiban P.
Published: September 2022

A new molecule, 3,5-dimethyl-2,6-bis(2,4-dichlorophenyl) piperidin-4-one was synthesized by a modified Mannich condensation of 2 moles of 2,4-dichlorobenzaldehyde, 1mole each of 3-pentanone and ammonium acetate (instead of amine in the typical procedure) in ethanol; recrystallized with ethanol to afford the pale yellow powder with 56% yield. The molecule was characterized by IR, 1H NMR,13C NMR and elemental analysis. Based on the NMR data, it is identified that the molecule exists in a chair conformation with equatorial orientation of all the substituents. Apart, few interesting NMR results are, (i) a broad singlet was observed for the active methine protons at C-3 and C-5, instead of a multiplet, (ii) significant deshielding of the protons at C-2 and C-6 due to the interaction of these protons with chlorine atoms at ortho positions (2’a and 6’a) of the phenyl groups; leads to restricted rotation of the phenyl groups as well, (iii) The ortho protons of 2,4-dichloro phenyl (2’e and 6’e) were also deshielded by nitrogen lone pair; about half of the deshielding magnitude is due to the protons at C-2 and C-6. Antioxidant efficacy of the molecule was verified with DPPH and ABTS methods.

Turismo y gentrificación: metaanálisis en torno al problema
Authors: Nuevo López Abraham
Published: September 2022

El objetivo principal de este trabajo es problematizar el concepto de gentrificación, su relación con el turismo y sus efectos negativos a nivel social, una cuestión que viene preocupando a no pocos estudiosos del fenómeno turístico en su vertiente social, económica, cultural, etc. El sector turístico, que afronta una crisis importante por el shock provocado por la pandemia de la COVID-19, tiene un reto pendiente respecto a cómo contribuye a frenar el proceso de gentrificación abierto en distintos núcleos urbanos a lo largo y ancho del mundo. La metodología empleada en la investigación es de tipo cualitativa. El resultado de la investigación demuestra que el gran desafío pasa por conciliar un turismo de calidad, sostenible, con un desarrollo urbanístico y social que no atente contra los intereses y expectativas vitales de los grupos sociales más desfavorecidos.

De esta forma, puede concluirse la presencia de una política pública marcadamente centralista, diseñada desde fuera de la región y con un acento fuertemente económico, que deja al sector privado la responsabilidad sobre lo que sucede en el territorio.
Mortalidad oficial y mortalidad sacramentada en la epidemia de cólera de 1834 en Vitoria
Authors: Ferreiro-Ardións Manuel
Published: September 2022

La consideración del cólera de 1834 en Vitoria como epidemia menor, derivada del deficiente recuento oficial, contrasta con su papel en la introducción efectiva de la patata en la dieta urbana. Se propone una contabilidad alternativa mediante registros sacramentales para determinar su alcance real. Frente a los 62 fallecimientos oficiales entre agosto y noviembre, se contabilizan 142 defunciones sacramentadas por encima de la media de su decenio. Se concluye que el recuento oficial solo contabilizó una pequeña fracción de afectados, probablemente por interés económico, no siendo representativo de la incidencia real. La mortalidad atribuible alcanzaría el doble de las cifras oficiales pudiendo triplicarlas, pues el cambio de tendencia sugiere un inicio de la epidemia a últimos de junio, y no en agosto, cuando se declara.

En cuanto a las aplicaciones, el trabajo es de utilidad para los gestores del turismo a fin de incidir sobre la realidad del sector. Las conclusiones indican que Cuenca-Ecuador es percibida por sus visitantes como una ciudad que se distingue por su legado histórico-cultural.
Construcción de escenarios urbano-energéticos “tendenciales” en ciudades intermedias. La ciudad de la plata como caso de estudio –Buenos Aires, Argentina- (2015-2040)
Authors: Chévez Pedro , Martini Irene , Discoli Carlos
Published: September 2022

Este trabajo presenta el desarrollo metodológico para la construcción de escenarios urbanoenergéticos “tendenciales” de largo plazo en ciudades intermedias. Como aspecto original, la metodología presenta un abordaje territorial con desagregación intra-urbana, siendo un enfoque no habitual en los trabajos de prospectiva, lo que permite identificar las criticidades de la ciudad de forma precisa y localizada para analizar su comportamiento futuro por medio de escenarios “tendenciales”. Esto permitirá orientar, en futuros trabajos, estrategias de mejoramiento que se contrastarán por medio de escenarios alternativos. Para su validación se utiliza a la ciudad de La Plata (Buenos Aires-Argentina) como caso de estudio, abordando la oferta y la demanda energética de forma general y el desarrollo de la metodología para el sector residencial en profundidad.
DScribe: Library of descriptors for machine learning in materials science
Authors: Himanen Lauri
Published: September 2022

This talk introduces DScribe which is a Python package for transforming atomic structures into fixed-size numerical fingerprints. These fingerprints are often called "descriptors" and they can be used in various tasks, including machine learning, visualization, similarity analysis, etc. DScribe provides user-friendly, off-the-shelf descriptor implementations and is freely available under the open-source Apache License 2.0.

This seminar will include several hands-on examples on how these descriptors can be used for different tasks, including property prediction through a regression model, data clustering through unsupervised learning, and visualization of complex chemical environments.

The package currently contains implementations for Coulomb matrix, Ewald sum matrix, sine matrix, Smooth Overlap of Atomic Positions (SOAP), Many-body Tensor Representation (MBTR), Local Many-body Tensor Representation (LMBTR), Atom-centered Symmetry Function (ACSF) and the Valle-Oganov descriptor.

Published: September 2022

Objectives: To evaluate the clinical and environmental ability of P. aeruginosa isolates to make biofilms and to determine their antimicrobial susceptibility patterns. Methods: Environmental swabs (144), air (28) and water samples (12) were collected from various wards of Gaza strip hospitals. Additionally, 158 clinical P. aeruginosa isolates were obtained from the microbiology laboratories of the same hospitals between July 21, 2019 and January 21, 2020. Samples were cultured and bacterial identification was performed using standard microbiological procedures. PCR was used to confirm the identity of P. aeruginosa. P. aeruginosa isolates were tested for their antimicrobial susceptibility patterns by the agar disk diffusion method. Both qualitative and quantitative methods assessed the biofilm formation by crystal violet and safranin stains. Results: Among the P. aeruginosa isolates (N=150), 90.0% were resistant for ceftazidime, (36.7%) aztreonam, (29.3%) gentamicin, (27.3%) levofloxacin, (22.0%) meropenem, (14.0%) piperacillin, (10.0%) amikacin and (9.3%) imipenem. The results for biofilm formation by tube method showed that 78.0% and 71.3% of the isolates were biofilm producer by crystal violet and safranin methods, respectively. Microtiter plate method demonstrated that 94.0% and 96.0% were biofilm producers by crystal violet and safranin, respectively. In addition, there was a statistical significance between the meropenem resistance and biofilm-forming ability of the isolates. Conclusions: High resistance rates were detected among P. aeruginosa isolates. The lowest rate of resistance was to imipenem and amikacin. As for the biofilm assessment, the tissue culture plate method showed higher detection rates than the tube method.

Exploring Student Success Strategies in Developmental Education at the Community College Level
Authors: Beck Karen
Published: September 2022

The problem investigated in this study was the low completion rates of students in mandated developmental education courses at a local community college in the mid-Atlantic region of the United States. The purpose of this study was to examine factors that may contribute to the persistence of community college students who have completed mandated developmental education courses. The qualitative study uses Tinto’s student departure theory as the conceptual framework to examine the lack of persistence of students in developmental education classes. The study included interviews with 8 students who have completed at least 1 developmental education course in the past 3 years. Data analysis included an extensive review of the interview transcripts to develop codes, categories, and themes to answer the research question. The findings of this study identify personal or academic persistence strategies that may assist community colleges in increasing the success rates of students in developmental education. Completing a credential has social change implications, as it may provide significant job opportunities and the ability to earn higher wages impacting overall quality of life. Moreover, an individual that receives an associate degree may earn 17% more in their occupation than their counterparts with a high school diploma or equivalent.

Published: September 2022

Research on innovative knowledge management tool of the visually impaired students’ mental health care for teachers, parents and public health personnel is an academic investigation for research and development purpose. Knowledge management was employed in the early stage of the investigation. The objectives of this study were comprised of 1) developing an innovation to be used by teachers, parents, and public health personnel to provide support to the visually impaired children; 2) sharing knowledge regarding mental health support of the visually impaired students to vision teachers, parents, and relevant public health personnel; and 3) outlining a number of approaches for mental health support to visually impaired children. This study began with an interview with relevant individuals to identify various issues of innovative development with knowledge management. A knowledge management team was formed with participating blind schools which aimed to measure the knowledge level of each school, to design and develop an innovation, to provide access to the knowledge and to identify methods for knowledge sharing. The innovation was adopted in five schools, where the presentation of the investigation results, and knowledge sharing forums were required. There were three main findings: 1) the innovative knowledge management tool was perceived as a handbook with both regular font and braille codes for teachers, parents, and public health personnel to assist visually impaired children with their mental health. The E1/E2 efficiency score of the handbook was 83.55/82.36 which was higher than the stated requirements; 2) Teachers, parents, and public health personnel received a statistically significant higher mean score of cognitive disabilities in mental health support of visually impaired children after the use of the handbook at the.05 level; and 3) a policy recommendation at school, Education Area Office, and Department of Mental Health served as a guideline of mental health support for children with visual impairment.
Sharing Knowledge, Making Place: Exploring “the Social” in Co/mmunity Living in London
Authors: John Gemma
Published: September 2022

This paper focuses on a building tour as a methodological intersection between anthropology and architecture, and an example of where a social scientist might intervene on a technical project and explore imaginaries of ‘the social’. It draws on participant observation on a tour around a shared living space in North West London that myself and a junior architect carried out as part of an architectural design competition, and larger consultancy project that involved making recommendations to shortlisted architects tasked with creating “community” in a new shared living space in North East London. Rather than examine the shortcomings of the building itself, the paper draws on the lens of anthropology to foreground the way in which people living in the building adapt their spaces to create the right “atmosphere”. It highlights the efforts of residents, who were dealing with the proximity of shared living, to sensorially detach yet share knowledge about communal living and in so doing craft their own version of “community”.
