Abstract:
BackgroundPeople increasingly communicate online, using visual communication mediums such as Skype and FaceTime. Growing demands on primary care services mean that new ways of providing patient care are being considered. Video consultation (VC) over the internet is one such mode.AimTo explore patients’ and clinicians’ experiences of VC.Design and settingSemi-structured interviews in UK primary care.MethodPrimary care clinicians were provided with VC equipment. They invited patients requiring a follow-up consultation to an online VC using the Attend Anywhere web-based platform. Participating patients required a smartphone, tablet, or video-enabled computer. Following VCs, semi-structured interviews were conducted with patients (n = 21) and primary care clinicians (n = 13), followed by a thematic analysis.ResultsParticipants reported positive experiences of VC, and stated that VC was particularly helpful for them as working people and people with mobility or mental health problems. VCs were considered superior to telephone consultations in providing visual cues and reassurance, building rapport, and improving communication. Technical problems, however, were common. Clinicians felt, for routine use, VCs must be more reliable and seamlessly integrated with appointment systems, which would require upgrading of current NHS IT systems.ConclusionThe visual component of VCs offers distinct advantages over telephone consultations. When integrated with current systems VCs can provide a time-saving alternative to face-to-face consultations when formal physical examination is not required, especially for people who work. Demand for VC services in primary care is likely to rise, but improved technical infrastructure is required to allow VC to become routine. However, for complex or sensitive problems face-to-face consultations remain preferable.

Abstract:
Visual Secret Sharing (VSS) is an increased applicability of traditional secret sharing. In VSS, the secret information is recovered by human visual system or lightweight computational device. There are two models available in VSS, one is Visual Cryptography (VC) which is introduced by Naor's in 1994 and other is a Random Grid (RG) based VSS which is proposed by Keren and Kafri. This state of the art covers both the models of VSS along with its application. The various application areas of VSS are visual authentication and identification, image encryption, access control, data hiding etc. The chapter has also covered various future enhancements in VC based on cryptanalysis, optimal pixel expansion, multiple secret encoding, progressive VC etc. Random Grid based VSS have some advantages over VC, which eliminates the need of Pixel expansion and codebook. But still, there is scope for the improvements in the contrast and the complexity of exiting algorithms. So there are various challenges and opportunities which make it an exciting research area to work upon.

Abstract:
Social media and online firms are currently facing severe challenges generating revenue through online banner ads, and for two decades, current studies in the information systems, advertising, and marketing literature have shown that online banner ad click-through rates are decreasing steadily (Idemudia, 2014; Idemudia et al., 2007; Li et al., 2012). To address these issues, the Visual-Cognitive (VC) model has been developed for online market places and Internet advertising. An experiment was conducted in which independent variables such as familiarity of online banner ads, perceived security of online banner ads, and matches between web users' needs and banner ad content were manipulated. The theoretical background for the VC model is the Visual Perception Theory. The VC model shows that perceived usefulness of online banner ads has a positive and significant effect on the intention to click online banner ads. Also, the VC model shows that perceived security of online banner ads, matches between web users' needs and banner ad contents, and perceived familiarity of online banner ads have positive and significant effects on perceived usefulness of those ads. These findings strongly support the Visual Perception Theories. Thus, the VC model has significant research and practical implications relating to social media and online firms.

Abstract:
This research aims to reveal the social representation of voluntary childlessness (VC) on Instagram, focusing on how individuals construct and defend their childfree identity in a digital visual environment. Grounded in Social Representations Theory (SRT), the analysis examines 212 posts from Instagram accounts dedicated to VC content. Using netnography—a qualitative method for studying online communities—and thematic analysis, recurring patterns in how VC is communicated and negotiated are explored. Posts were selected based on relevant hashtags (e.g., #childfreebychoice) and representation-focused content, excluding promotional or antinatalist material. The analysis identifies three key mechanisms of representation: anchoring (e.g., the use of terms like “childfree” instead of “childless”), objectification (e.g., memes that visualize social stigmas), and repudiation (e.g., direct responses to common stigmas such as regret or selfishness). Findings demonstrate how Instagram functions as a space for identity performance, defensive communication, and resistance to dominant pronatalist narratives. This research contributes to digital representation scholarship by showing how platform affordances and user-generated content reshape marginalized social identities and offers practical implications for understanding how visual media enables counter-narratives that challenge traditional norms around parenthood.

Abstract:
The development of mobile Internet and the popularization of intelligent sensor devices greatly facilitate the generation and transmission of massive multimedia data including medical images and pathological models on the open network. The popularity of artificial intelligence (AI) technologies has greatly improved the efficiency of medical image recognition and diagnosis. However, it also poses new challenges to the security and privacy of medical data. The leakage of medical images related to users’ privacy is emerging one after another. The existing privacy protection methods based on cryptography or watermarking often bring a burden to image transmission. In this paper, we propose a privacy-preserving recognition network for medical images (called MPVCNet) to solve these problems. MPVCNet uses visual cryptography (VC) to transmit images by sharing. Benefiting from the secret-sharing characteristics of VC, MPVCNet can securely transmit images in clear text, which can both protect privacy and mitigate performance loss. Aiming at the problem that VC is easy to forge, we combine trusted computing environments (TEE) and blind watermarking technologies to embed verification information into sharing images. We further leverage the transfer learning technology to abate the side effect resulting from the use of visual cryptography. The results of the experiment show that our approach can maintain the trustworthiness and recognition performance of the recognition networks while protecting the privacy of medical images.

Abstract:
Information now a day"s seems to have become abundant and the secure transmission and visualization of it has been a challenge. The major security concerns are of Authentication, Confidentiality and Data Integrity. In regard to this, the various security methodologies have been introduced and Cryptography is one of the schemes where the information is transferred in the disguise form and only authentic user can reveal the exact information. Various Cryptographic techniques has played a very vital role in this regard, among which Visual Cryptographic System(VCS) is one of such kind where the secret data (image, text etc) is encoded into multiple images and decoded using Human Visual System(HVS) without having to tedious calculations and sound knowledge of Cryptography. VC is one of such methodology where the secret information is bifurcated into many disguise images and on super imposing these images, the original secret information is revealed, using Human Visual System(HVS) unlike the traditional cryptography where lot of complex mathematical and time consuming calculation are to be performed. In this paper study of various VC techniques has been done based on number of shares, number of secret messages and types of shares in the cases of Grayscale Image.

Abstract:
Benefiting from the intelligent Medical Internet of Things (IoMT), the medical industry has dramatically improved its quality and productivity. The transmission of biomedical data in an open and untrusted network poses a new challenge to the privacy protection of patient information. The low processing power of IoMT limited the application of traditional encryption to protect sensitive data. In this paper, we developed a new data protection model for medical images. The model uses visual cryptography (VC) to store biomedical data in a separate database, which can transfer the sensitive data of patients simply and securely. To alleviate the degradation of biomedical recognition performance caused by VC-based noise, we further use transfer learning to train an optimized neural network. The experimental results show that this proposed method provides privacy in the IoMT environment and maintains the high accuracy of biomedical recognition.

Abstract:
<abstract> <p>In today's digital landscape, securing multimedia visual information—specifically color images—is of critical importance across a range of sectors, including the burgeoning fields of logistics and supply chain management. Traditional Visual Cryptography (VC) schemes lay the groundwork for encrypting visual data by fragmenting a secret image into multiple shares, thereby ensuring no single share divulges the secret. Nevertheless, VC faces challenges in ascertaining the integrity of reconstructed images, especially when shares are manipulated maliciously. Existing solutions often necessitate additional shares or a trusted third party for integrity verification, thereby adding complexity and potential security risks. This paper introduces a novel Cheating-Resistant Visual Cryptographic Protocol (CRVC) for Color Images that aims to address these limitations. Utilizing self-computational models, this enhanced protocol simplifies the integrated integrity verification process, eliminating the need for extra shares. A standout feature is its capability to securely transmit meaningful shares for color images without compromising the quality of the reconstructed image as the PSNR maintains to be ∞. Experimental findings substantiate the protocol's resilience against quality degradation and its effectiveness in verifying the authenticity of the reconstructed image. This innovative approach holds promise for a wide array of applications, notably in sectors requiring secure document transmission, such as Logistics and Supply Chain Management, E-Governance, Medical and Military Applications.</p> </abstract>

Abstract:
Glaucoma is a chronic optic neuropathy characterized by irreversible damage to the retinal nerve fiber layer (RNFL), resulting in changes in the visual field (VC). Glaucoma screening is performed through a complete ophthalmological examination, using images of the optic papilla obtained in vivo for the evaluation of glaucomatous characteristics, eye pressure, and visual field. Identifying the glaucomatous papilla is quite important, as optical papillary images are considered the gold standard for tracking. Therefore, this article presents a review of the diagnostic methods used to identify the glaucomatous papilla through technology over the last five years. Based on the analyzed works, the current state-of-the-art methods are identified, the current challenges are analyzed, and the shortcomings of these methods are investigated, especially from the point of view of automation and independence in performing these measurements. Finally, the topics for future work and the challenges that need to be solved are proposed.

Steganography and visual cryptography are essen- tial techniques in secure digital communication, allowing for covert information exchange and secure data transmission. This paper explores various steganographic methods, with a focus on image steganography, including Least Significant Bit (LSB) substitution, transform domain approaches, and advanced meth- ods such as Spread Spectrum and Patchwork steganography. Additionally, the study examines visual cryptography (VC), which enables image encryption through secret sharing techniques. The effectiveness of different steganographic approaches is analyzed based on criteria such as invisibility, payload capacity, robustness, and resistance to detection. Comparative studies on stegano- graphic techniques in different image formats (BMP, GIF, JPEG) highlight their strengths and limitations. Furthermore, emerging research integrating steganography with deep learning and real- time encryption standards is discussed. The paper also reviews steganalysis techniques used for detecting hidden information, emphasizing the ongoing challenge of developing robust and generalizable detection methods. The findings contribute to the advancement of secure data hiding techniques, addressing the evolving demands of cybersecurity and covert communication in the digital era.

Abstract:
Background A vision center (VC) is a significant eye care service model to strengthen primary eye care services. VCs have been set up at the block level, covering a population of 150,000-250,000 in rural areas in North India. Inadequate use by rural communities is a major challenge to sustainability of these VCs. This not only reduces the community’s vision improvement potential but also impacts self-sustainability and limits expansion of services in rural areas. The current literature reports a lack of awareness regarding eye diseases and the need for care, social stigmas, low priority being given to eye problems, prevailing gender discrimination, cost, and dependence on caregivers as factors preventing the use of primary eye care. Objective Our organization is planning an awareness-cum-engagement intervention—door-to-door basic eye checkup and visual acuity screening in VCs coverage areas—to connect with the community and improve the rational use of VCs. Methods In this randomized, parallel-group experimental study, we will select 2 VCs each for the intervention arm and the control arm from among poor, low-performing VCs (ie, walk-in of ≤10 patients/day) in our 2 operational regions (Vrindavan, Mathura District, and Mohammadi, Kheri District) of Uttar Pradesh. Intervention will include door-to-door screening and awareness generation in 8-12 villages surrounding the VCs, and control VCs will follow existing practices of awareness generation through community activities and health talks. Data will be collected from each VC for 4 months of intervention. Primary outcomes will be an increase in the number of walk-in patients, spectacle advise and uptake, referral and uptake for cataract and specialty surgery, and operational expenses. Secondary outcomes will be uptake of refraction correction and referrals for cataract and other eye conditions. Differences in the number of walk-in patients, referrals, uptake of services, and cost involved will be analyzed. Results Background work involved planning of interventions and selection of VCs has been completed. Participant recruitment has begun and is currently in progress. Conclusions Through this study, we will analyze whether our door-to-door intervention is effective in increasing the number of visits to a VC and, thus, overall sustainability. We will also study the cost-effectiveness of this intervention to recommend its scalability.

Abstract:
Real-time multilingual phrase detection from/during online video presentations—to support instant remote diagnostics—requires near real-time visual (textual) object detection and preprocessing for further analysis. Connecting remote specialists and sharing specific ideas is most effective using the native language. The main objective of this paper is to analyze and propose—through DEtection TRansformer (DETR) models, architectures, hyperparameters—recommendation, and specific procedures with simplified methods to achieve reasonable accuracy to support real-time textual object detection for further analysis. The development of real-time video conference translation based on artificial intelligence supported solutions has a relevant impact in the health sector, especially on clinical practice via better video consultation (VC) or remote diagnosis. The importance of this development was augmented by the COVID-19 pandemic. The challenge of this topic is connected to the variety of languages and dialects that the involved specialists speak and that usually needs human translator proxies which can be substituted by AI-enabled technological pipelines. The sensitivity of visual textual element localization is directly connected to complexity, quality, and the variety of collected training data sets. In this research, we investigated the DETR model with several variations. The research highlights the differences of the most prominent real-time object detectors: YOLO4, DETR, and Detectron2, and brings AI-based novelty to collaborative solutions combined with OCR. The performance of the procedures was evaluated through two research phases: a 248/512 (Phase1/Phase2) record train data set, with a 55/110 set of validated data instances for 7/10 application categories and 3/3 object categories, using the same object categories for annotation. The achieved score breaks the expected values in terms of visual text detection scope, giving high detection accuracy of textual data, the mean average precision ranging from 0.4 to 0.65.

Abstract:
Background/Objectives: The successful integration of video consultations in routine hospital care requires further research. This study explores how healthcare professionals experienced and engaged with a pilot training program in video consultations (VCs), focusing on patient-centred communication and technical skills. Methods: A qualitative study was conducted at a gynaecological outpatient clinic in a Danish university hospital. In October 2022, healthcare professionals (n = 8) piloted a training program in VCs with patients suffering from gynaecological disorders, followed by semi-structured interviews. Our data analysis was inductive and inspired by thematic analysis, as proposed by Braun and Clarke. Results: Our analysis resulted in an overall theme, namely feasible, with context-dependent considerations, and followed by four other themes:, namely that (1) pre in situ training presents benefits and challenges, (2) consultation via video can be an advantage to consultations via phone or in-clinic, (3) individual planning and organising is a must, and (4) video consultation calls for new competencies. Conclusions: Our study indicates that a training program focusing on patient-centred communication, technical skills and in situ training with peer feedback is relevant when implementing VCs. Visual contact was an advantage of VC versus phone; however, patient triage was identified as essential when planning VCs. Overall, VCs are feasible in a gynaecological outpatient setting when their implementation is supported by an in situ training program and with ongoing technical support available.

Abstract:
The segmentation and extraction of oilseed rape crop rows are crucial steps in visual navigation line extraction. Agricultural autonomous navigation robots face challenges in path recognition in field environments due to factors such as complex crop backgrounds and varying light intensities, resulting in poor segmentation and slow detection of navigation lines in oilseed rape crops. Therefore, this paper proposes VC-UNet, a lightweight semantic segmentation model that enhances the U-Net model. Specifically, VGG16 replaces the original backbone feature extraction network of U-Net, Convolutional Block Attention Module (CBAM) are integrated at the upsampling stage to enhance focus on segmentation targets. Furthermore, channel pruning of network convolution layers is employed to optimize and accelerate the model. The crop row trapezoidal ROI regions are delineated using end-to-end vertical projection methods with serialized region thresholds. Then, the centerline of oilseed rape crop rows is fitted using the least squares method. Experimental results demonstrate an average accuracy of 94.11% for the model and an image processing speed of 24.47 fps/s. After transfer learning for soybean and maize crop rows, the average accuracy reaches 91.57%, indicating strong model robustness. The average yaw angle deviation of navigation line extraction is 3.76°, with a pixel average offset of 6.13 pixels. Single image transmission time is 0.009s, ensuring real-time detection of navigation lines. This study provides upper-level technical support for the deployment of agricultural robots in field trials.

Abstract:
BACKGROUND: Anterior cruciate ligament tear is a serious knee injury with implications for central nervous system (CNS) plasticity. To perform simple knee movements, people with a history of ACL reconstruction (ACL-R) engage cross-modal brain regions and when challenged with cognitive-motor dual-tasks, physical performance deteriorates. Therefore, people with ACL-R may increase visual-cognitive neural processes for motor control. CLINICAL QUESTION: What components of CNS plasticity should the rehabilitation practitioner target with interventions, and how can practitioners augment rehabilitation exercises to target injury associated plasticity? KEY RESULTS: This clinical commentary (1) describes the neurophysiological foundation for visual-cognitive compensation after ACL-R, (2) provides a theoretical rationale for implementing visual-cognitive challenges throughout the return to sport (RTS) continuum, and (3) presents a framework for implementing visual-cognitive challenges from the acute phases of rehabilitation. The ‘Visual-Cognitive Control Chaos Continuum (VC-CCC) framework consists of five training difficulties that progress visual-cognitive challenges from high control to high chaos, to better represent the demands of sport. CLINICAL APPLICATION: The VC-CCC framework augments traditional rehabilitation so that each exercise can progress to increase difficulty and promote sensorimotor and visual-cognitive adaptation after ACL-R.

Abstract:
Visual Cryptography (VC) is a process employed for the maintenance of secret information by hiding the secret messages that are embedded within the images. Typically, an image is partitioned into a number of shares that are stacked over one another in order to reconstruct back the original image accurately. The major limitation that existed in the traditional VC techniques is pixel expansion, in which pixel expansion is replaced with a number of sub-pixels in individual share, which causes a considerable impact on the contrast and resolution of the image that further gradually decreases the quality of the image. VC is named for its essential characteristics, such as transmitting the images with two or more shares with an equal number of black pixels and color pixel distribution. The secret message can be decrypted using Human Visual System (HVS). In this paper, 50 research papers are reviewed based on various classification algorithms, which are effectively used for the VC technique. The classification algorithms are categorized into three types, namely, meta-heuristic, heuristic, and evolutionary, and the research issues and challenges confronted by the existing techniques are reported in this survey. Moreover, the analysis is done based on the existing research works by considering the classification algorithms, tools, and evaluation metrics.

Abstract:
IntroductionVisual communications (VC) play a crucial role in effectively conveying public health data to diverse audiences, including policymakers, healthcare professionals, and the general public. Although the U.S. government invests heavily in health data and data accessibility, health data are not entirely accessible or easily understood. This can be attributed to data sharing and visualization challenges. VC challenges have created public health information gaps which are compounded in emergencies such as the COVID-19 pandemic, potentially impacting poor health outcomes and increasing health inequities.ObjectiveTo examine visualization tools and techniques effective for public health visual data communication.MethodsA scoping review was conducted to summarize the available evidence related to visualization techniques and tools for public health visual data communication as well as related principles and best practices. Original peer-reviewed articles published in English that involve visualization, user-centered design of visual public health applications/interfaces, visual analytics, infographics, or dashboards from PubMed database from 2020 to 2024 were included. Also, review articles, commentaries, editorials, posters, systematic and scoping articles were excluded from this review. In all, twenty-eight (28) studies were included.ResultsThere were 25 different visualization techniques identified which included charts and graphs (e.g., bar charts, line charts, pie charts, bubble charts, box plots, scatter plots), maps (e.g., choropleth maps, hotspot maps, and heatmaps), and specialized visualizations (e.g., sunburst diagrams, alluvial plots, upset plots, circos). These visuals were displayed employing different programming and statistical tools and libraries like R, Python, Power BI, Tableau, ArcGIS, and custom web-based applications. The visuals measured different types of data accessibility, pattern and trends identification, association and relationships of univariate and bivariate data, as well as exploring multidimensional forms of health data. The visualizations were applied in different public health domains, such as HIV prevention and care, public health communication, interventions, surveillance, policy measures and decision-making, and improving health education.ConclusionDashboards and web-based tools combined with static visualizations like charts, maps, or specialized plots can help with data exploration, pattern recognition, and dissemination of health information. Effective communication of public health data promotes informed decision-making, creates awareness, and leads to improved and better health outcomes.

Abstract:
PurposeThe objective quantitation of visual function in patients with advanced retinitis pigmentosa (RP) presents a difficult challenge due to the weak visual function of these patients. This study utilized magnetic resonance imaging (MRI) to assess the function and structure of the visual cortex (VC) in patients with RP and quantitatively categorize them.Materials and MethodsTwenty-three patients with RP and ten healthy controls (HCs) were enrolled for MRI examinations. The patients were divided into form perception (FP) and no form perception (NFP) groups. Participants underwent structural MRI scans, and two visual task functional MRI scans were performed using stimuli, including white flash and black and white checkerboard patterns. Eight regions of interest (ROIs) were studied. In structural MRI, the gray matter volume (GMV) was compared in the ROIs. In the two visual tasks, the response intensity and functional connectivity (FC) of ROIs were also compared separately. Correlation analysis was performed to explore the correlations between the structural and functional parameters.ResultsIn the structural analysis, the GMV in Brodmann areas 17, 18, and 19 of the FP and NFP groups was significantly lower than that of HCs. Regarding the functional data, the response intensity in the VC of both the FP and NFP groups was significantly lower than that in HCs. The response in Brodmann areas 17, 18, and 19 obtained using the pattern stimulus was significantly lower in the NFP group than in the FP group. For the FC comparison, the FP and NFP groups exhibited significantly lower values in several pathways than the HCs, and FC in the ipsilateral V1–contralateral V1 pathway in the flash task was significantly lower in the NFP group than in the FP group. A positive correlation between response intensity and GMV was observed in Brodmann areas 17, 18, and 19 in both flash and pattern visual tasks.ConclusionMagnetic resonance imaging was an effective tool to objectively and quantitatively evaluate the visual function of patients with advanced RP. Response intensity and FC were effective parameters to distinguish FP and NFP patients. A positive correlation between response intensity and GMV was observed in the VC.

Abstract:
Abstract Background and Aims Cardiovascular disease is the major cause of death in patients with chronic kidney disease (CKD). It is increasingly believed that the presence of vascular calcification (VC) increases the risk of mortality due to cardiovascular events. VC is very common in CKD, especially in hemodialysis patient. To improve the life expectancy of patients, it is important to detect VC in the early stages of the disease. There are several ways to discover VC such as computed tomography (CT) scans, echocardiography, and X-Ray among others. However, one of the best options is the usage of X-ray images because is an affordable and simpler process in comparison to using CT scans or echocardiography. However, the problem with X-ray images is the difficulty of finding a well-trained professional that can detect the VC after analyzing the images which leads to possible misleading diagnoses. The goal of this study is to develop a prototype that detects Vascular Calcification from X-ray images in an automated way using the power of Convolutional Neural Networks (CNN). Method To train a CNN to detect VC from lumbosacral spine X-ray images, a set of 700 DICOM files complemented with 236 JPEG images was available. After getting the images, they had to be anonymized, and data, such as name and age was removed from each image. Then, the images were divided into three datasets: Train, Test, and Validation. Given that the dataset was not balanced between the pictures with VC (Positive) and those with no VC (Negative), it had to be reduced (Table 1). The next step was implemented to clean the images and prepare them to feed the CNN. An example of preprocessing is that some X-ray images were of the entire body. For the analysis, the VC detection was assessed at the anterior and the posterior walls of the abdominal aorta adjacent to vertebrae L1-L4. In addition to that, the DICOM images were converted to JPEG. After having the dataset prepared, a CNN architecture had to be selected. To achieve it, a revision of modern CNN architectures was performed. Two items were considered when selecting these: the performance on the ImageNet Large Scale Visual Recognition Challenge (ILSVRC) and if there was an available pre-trained model. With that criteria, pre-trained EfficientNet-B0 and ResNet50 models were used to build the prototype due to the limited dataset. Results After having the dataset prepared, the architectures selected, and the pre-trained models, the Training, Validation and Test stages were executed. For Training, with EfficientNet-B0, the Accuracy was 86.9%, while for Validation, the Accuracy was 57.4% (Fig. 1). Using the RestNet50 model, the precision was 90.506% during Training, while for Validation, it was 54.8% (Fig. 2). Finally, during the Testing stage, ResNet50 had a better performance, because EfficientNetB0 detected 80% for the negative class and 60% for the positive class. After the CNN models were trained, an additional validation stage was performed to compare the model results with the analysis made by a radiologist and a nephrologist. This comparison determined that the model performed better with images having VC, while it was less accurate with images having no presence of VC. This contrast could have different reasons, one being possible false-positive images. Conclusion This study created a CNN model using pre-trained models on top of modern architectures such as EfficientNet-B0 and ResNet50. Tools were used to prepare the images as well as to train, validate and test the model. The Transfer Learning helped to build a model faster, giving high Accuracy rates with only a few images due to the limited dataset. However, the model could give better results if a wider and balanced set of images is available. Also, a better pre-processing stage can be executed to reduce false-positive images. For future work, this model can be used as the core of a system that not only accurately detects Vascular Calcification from X-Ray images, but also can determine the level of calcification using measures such as the Kauppila Index or Adragao.

Abstract:
IntroductionRegional identity is a constant construction, in which landscape, human activity and cultural imaginary build a narrative of place. For the Tasmanian Midlands, the interactions between history, ecology and agriculture both define place and present problems in how to recognise, communicate and balance these interactions. In this sense, regionality is defined not so much as a relation of margin to centre, but as a specific accretion of environmental and cultural histories. According weight to more-than-human perspectives, a region can be seen as a constellation of plant, animal and human interactions and demands, where creative art and design can make space and give voice to the dynamics of exchange between the landscape and its inhabitants. Consideration of three recent art and design projects based in the Midlands reveal the potential for cross-disciplinary research, embedded in both environment and community, to create distinctive and specific forms of connectivity that articulate a regional identify.The Tasmanian Midlands have been identified as a biodiversity hotspot (Australian Government), with a long history of Aboriginal cultural management disrupted by colonial invasion. Recent archaeological work in the Midlands, including the Kerry Lodge Archaeology and Art Project, has focused on the use of convict labour during the nineteenth century in opening up the Midlands for settler agriculture and transport. Now, the Midlands are placed under increasing pressure by changing agricultural practices such as large-scale irrigation. At the same time as this intensification of agricultural activity, significant progress has been made in protecting, preserving and restoring endemic ecologies. This progress has come through non-government conservation organisations, especially Greening Australia and their program Tasmanian Island Ark, and private landowners placing land under conservation covenants. These pressures and conservation activities give rise to research opportunities in the biological sciences, but also pose challenges in communicating the value of conservation and research outcomes to a wider public. The Species Hotel project, beginning in 2016, engaged with the aims of restoration ecology through speculative design while The Marathon Project, a multi-year curatorial art project based on a single property that contains both conservation and commercially farmed zones.This article questions the role of regionality in these three interconnected projects—Kerry Lodge, Species Hotel, and Marathon—sited in the Tasmanian Midlands: the three projects share a concern with the specificities of the region through engagement with specifics sites and their histories and ecologies, while also acknowledging the forces that shape these sites as far more mobile and global in scope. It also considers the interdisciplinary nature of these projects, in the crossover of art and design with ecological, archaeological and agricultural practices of measuring and intervening in the land, where communication and interpretation may be in tension with functionality. These projects suggest ways of working that connect the ecological and the cultural spheres; importantly, they see rural locations as sites of knowledge production; they test the value of small-scale and ephemeral interventions to explore the place of art and design as intervention within colonised landscape.Regions are also defined by overlapping circles of control, interest, and authority. We test the claim that these projects, which operate through cross-disciplinary collaboration and network with a range of stakeholders and community groups, successfully benefit the region in which they are placed. We are particularly interested in the challenges of working across institutions which both claim and enact connections to the region without being centred there. These projects are initiatives resulting from, or in collaboration with, University of Tasmania, an institution that has taken a recent turn towards explicitly identifying as place-based yet the placement of the Midlands as the gap between campuses risks attenuating the institution’s claim to be of this place. Paul Carter, in his discussion of a regional, site-specific collaboration in Alice Springs, flags how processes of creative place-making—operating through mythopoetic and story-based strategies—requires a concrete rather than imagined community that actively engages a plurality of voices on the ground. We identify similar concerns in these art and design projects and argue that iterative and long-term creative projects enable a deeper grappling with the complexities of shared regional place-making. The Midlands is aptly named: as a region, it is defined by its geographical constraints and relationships to urban centres. Heading south from the northern city of Launceston, travellers on the Midland Highway see scores of farming properties networking continuously for around 175 kilometres south to the outskirts of Brighton, the last major township before the Tasmanian capital city of Hobart. The town of Ross straddles latitude 42 degrees south—a line that has historically divided Tasmania into the divisions of North and South. The region is characterised by extensive agricultural usage and small remnant patches of relatively open dry sclerophyll forest and lowland grassland enabled by its lower attitude and relatively flatter terrain. The Midlands sit between the mountainous central highlands of the Great Western Tiers and the Eastern Tiers, a continuous range of dolerite hills lying south of Ben Lomond that slope coastward to the Tasman Sea. This area stretches far beyond the view of the main highway, reaching east in the Deddington and Fingal valleys. Campbell Town is the primary stopping point for travellers, superseding the bypassed towns, which have faced problems with lowering population and resulting loss of facilities.Image 1: Southern Midland Landscape, Ross, Tasmania, 2018. Image Credit: Patrick Sutczak.Predominantly under private ownership, the Tasmanian Midlands are a contested and fractured landscape existing in a state of ecological tension that has occurred with the dominance of western agriculture. For over 200 years, farmers have continually shaped the land and carved it up into small fragments for different agricultural agendas, and this has resulted in significant endemic species decline (Mitchell et al.). The open vegetation was the product of cultural management of land by Tasmanian Aboriginal communities (Gammage), attractive to settlers during their distribution of land grants prior to the 1830s and a focus for settler violence. As documented cartographically in the Centre for 21st Century Humanities’ Colonial Frontier Massacres in Central and Eastern Australia 1788–1930, the period 1820–1835, and particularly during the Black War, saw the Midlands as central to the violent dispossession of Aboriginal landowners. Clements argues that the culture of violence during this period also reflected the brutalisation that the penal system imposed upon its subjects. The cultivation of agricultural land throughout the Midlands was enabled by the provision of unfree convict labour (Dillon). Many of the properties granted and established during the colonial period have been held in multi-generational family ownership through to the present.Within this patchwork of private ownership, the tension between visibility and privacy of the Midlands pastures and farmlands challenges the capacity for people to understand what role the Midlands plays in the greater Tasmanian ecology. Although half of Tasmania’s land areas are protected as national parks and reserves, the Midlands remains largely unprotected due to private ownership. When measured against Tasmania’s wilderness values and reputation, the dry pasturelands of the Midland region fail to capture an equivalent level of visual and experiential imagination. Jamie Kirkpatrick describes misconceptions of the Midlands when he writes of “[f]latness, dead and dying eucalypts, gorse, brown pastures, salt—environmental devastation […]—these are the common impression of those who first travel between Spring Hill and Launceston on the Midland Highway” (45). However, Kirkpatrick also emphasises the unique intimate and intricate qualities of this landscape, and its underlying resilience. In the face of the loss of paddock trees and remnants to irrigation, change in species due to pasture enrichment and introduction of new plant species, conservation initiatives that not only protect but also restore habitat are vital. The Tasmanian Midlands, then, are pastoral landscapes whose seeming monotonous continuity glosses over the radical changes experienced in the processes of colonisation and intensification of agriculture.Underlying the Present: Archaeology and Landscape in the Kerry Lodge ProjectThe major marker of the Midlands is the highway that bisects it. Running from Hobart to Launceston, the construction of a “great macadamised highway” (Department of Main Roads 10) between 1820–1850, and its ongoing maintenance, was a significant colonial project. The macadam technique, a nineteenth century innovation in road building which involved the laying of small pieces of stone to create a surface that was relatively water and frost resistant, required considerable but unskilled labour. The construction of the bridge at Kerry Lodge, in 1834–35, was simultaneous with significant bridge buildings at other major water crossings on the highway, (Department of Main Roads 16) and, as the first water crossing south of Launceston, was a pinch-point through which travel of prisoners could be monitored and controlled. Following the completion of the bridge, the site was used to house up to 60 male convicts in a road gang undergoing secondary punishment (1835–44) and then in a labour camp and hiring depot until 1847. At the time of the La Trobe report (1847), the buildings were noted as being in bad condition (Brand 142–43). After the station was disbanded, the use of the buildings reverted to the landowners for use in accommodation and agricultural storage.Archaeological research at Kerry Lodge, directed by Eleanor Casella, investigated the spatial and disciplinary structures of smaller probation and hiring depots and the living and working conditions of supervisory staff. Across three seasons (2015, 2016, 2018), the emerging themes of discipline and control and as well as labour were borne out by excavations across the site, focusing on remnants of buildings close to the bridge. This first season also piloted the co-presence of a curatorial art project, which grew across the season to include eleven practitioners in visual art, theatre and poetry, and three exhibition outcomes. As a crucial process for the curatorial art project, creative practitioners spent time on site as participants and observers, which enabled the development of responses that interrogated the research processes of archaeological fieldwork as well as making connections to the wider historical and cultural context of the site. Immersed in the mundane tasks of archaeological fieldwork, the practitioners involved became simultaneously focused on repetitive actions while contemplating the deep time contained within earth. This experience then informed the development of creative works interrogating embodied processes as a language of site.The outcome from the first fieldwork season was earthspoke, an exhibition shown at Sawtooth, an artist-run initiative in Launceston in 2015, and later re-installed in Franklin House, a National Trust property in the southern suburbs of Launceston.Images 2 and 3: earthspoke, 2015, Installation View at Sawtooth ARI (top) and Franklin House (bottom). Image Credits: Melanie de Ruyter.This recontextualisation of the work, from contemporary ARI (artist run initiative) gallery to National Trust property enabled the project to reach different audiences but also raised questions about the emphases that these exhibition contexts placed on the work. Within the white cube space of the contemporary gallery, connections to site became more abstracted while the educational and heritage functions of the National Trust property added further context and unintended connotations to the art works.Image 4: Strata, 2017, Installation View. Image Credit: Karen Hall.The two subsequent exhibitions, Lines of Site (2016) and Strata (2017), continued to test the relationship between site and gallery, through works that rematerialised the absences on site and connected embodied experiences of convict and archaeological labour. The most recent iteration of the project, Strata, part of the Ten Days on the Island art festival in 2017, involved installing works at the site, marking with their presence the traces, fragments and voids that had been reburied when the landscape returned to agricultural use following the excavations. Here, the interpretive function of the works directly addressed the layered histories of the landscape and underscored the scope of the human interventions and changes over time within the pastoral landscape. The interpretative role of the artworks formed part of a wider, multidisciplinary approach to research and communication within the project. University of Manchester archaeology staff and postgraduate students directed the excavations, using volunteers from the Launceston Historical Society. Staff from Launceston’s Queen Victorian Museum and Art Gallery brought their archival and collection-based expertise to the site rather than simply receiving stored finds as a repository, supporting immediate interpretation and contextualisation of objects. In 2018, participation from the University of Tasmania School of Education enabled a larger number of on-site educational activities than afforded by previous open days. These multi-disciplinary and multi-organisational networks, drawn together provisionally in a shared time and place, provided rich opportunities for dialogue. However, the challenges of sustaining these exchanges have meant ongoing collaborations have become more sporadic, reflecting different institutional priorities and competing demands on participants. Even within long-term projects, continued engagement with stakeholders can be a challenge: while enabling an emerging and concrete sense of community, the time span gives greater vulnerability to external pressures. Making Home: Ecological Restoration and Community Engagement in the Species Hotel ProjectImages 5 and 6: Selected Species Hotels, Ross, Tasmania, 2018. Image Credits: Patrick Sutczak. The Species Hotels stand sentinel over a river of saplings, providing shelter for animal communities within close range of a small town. At the township of Ross in the Southern Midlands, work was initiated by restoration ecologists to address the lack of substantial animal shelter belts on a number of major properties in the area. The Tasmania Island Ark is a major Greening Australia restoration ecology initiative, connecting 6000 hectares of habitat across the Midlands. Linking larger forest areas in the Eastern Tiers and Central Highlands as well as isolated patches of remnant native vegetation, the Ark project is vital to the ongoing survival of local plant and animal species under pressure from human interventions and climate change. With fragmentation of bush and native grasslands in the Midland landscape resulting in vast open plains, the ability for animals to adapt to pasturelands without shelter has resulted in significant decline as animals such as the critically endangered Eastern Barred Bandicoot struggle to feed, move, and avoid predators (Cranney). In 2014 mass plantings of native vegetation were undertaken along 16km of the serpentine Macquarie River as part of two habitat corridors designed to bring connectivity back to the region. While the plantings were being established a public art project was conceived that would merge design with practical application to assist animals in the area, and draw community and public attention to the work that was being done in re-establishing native forests. The Species Hotel project, which began in 2016, emerged from a collaboration between Greening Australia and the University of Tasmania’s School of Architecture and Design, the School of Land and Food, the Tasmanian College of the Arts and the ARC Centre for Forest Value, with funding from the Ian Potter Foundation. The initial focus of the project was the development of interventions in the landscape that could address the specific habitat needs of the insect, small mammal, and bird species that are under threat. First-year Architecture students were invited to design a series of structures with the brief that they would act as ‘Species Hotels’, and once created would be installed among the plantings as structures that could be inhabited or act as protection. After installation, the privately-owned land would be reconfigured so to allow public access and observation of the hotels, by residents and visitors alike. Early in the project’s development, a concern was raised during a Ross community communication and consultation event that the surrounding landscape and its vistas would be dramatically altered with the re-introduced forest. While momentary and resolved, a subtle yet obvious tension surfaced that questioned the re-writing of an established community’s visual landscape literacy by non-residents. Compact and picturesque, the architectural, historical and cultural qualities of Ross and its location were not only admired by residents, but established a regional identity. During the six-week intensive project, the community reach was expanded beyond the institution and involved over 100 people including landowners, artists, scientists and school children from the region (Wright), attempting to address and channel the concerns of residents about the changing landscape. The multiple timescales of this iterative project—from intensive moments of collaboration between stakeholders to the more-than-human time of tree growth—open spaces for regional identity to shift as both as place and community. Part of the design brief was the use of fully biodegradable materials: the Species Hotels are not expected to last forever. The actual installation of the Species Hotelson site took longer than planned due to weather conditions, but once on site they were weathering in, showing signs of insect and bird habitation. This animal activity created an opportunity for ongoing engagement. Further activities generated from the initial iteration of Species Hotel were the Species Hotel Day in 2017, held at the Ross Community Hall where presentations by scientists and designers provided feedback to the local community and presented opportunities for further design engagement in the production of ephemeral ‘species seed pies’ placed out in and around Ross. Architecture and Design students have gone on to develop more examples of ‘ecological furniture’ with a current focus on insect housing as well as extrapolating from the installation of the Species Hotels to generate a VR visualisation of the surrounding landscape, game design and participatory movement work that was presented as part of the Junction Arts Festival program in Launceston, 2017. The intersections of technologies and activities amplified the lived in and living qualities of the Species Hotels, not only adding to the connectivity of social and environmental actions on site and beyond, but also making a statement about the shared ownership this project enabled.Working Property: Collaboration and Dialogues in The Marathon Project The potential of iterative projects that engage with environmental concerns amid questions of access, stewardship and dialogue is also demonstrated in The Marathon Project, a collaborative art project that took place between 2015 and 2017. Situated in the Northern Midland region of Deddington alongside the banks of the Nile River the property of Marathon became the focal point for a small group of artists, ecologists and theorists to converge and engage with a pastoral landscape over time that was unfamiliar to many of them. Through a series of weekend camps and day trips, the participants were able to explore and follow their own creative and investigative agendas. The project was conceived by the landowners who share a passion for the history of the area, their land, and ideas of custodianship and ecological responsibility. The intentions of the project initially were to inspire creative work alongside access, engagement and dialogue about land, agriculture and Deddington itself. As a very small town on the Northern Midland fringe, Deddington is located toward the Eastern Tiers at the foothills of the Ben Lomond mountain ranges. Historically, Deddington is best known as the location of renowned 19th century landscape painter John Glover’s residence, Patterdale. After Glover’s death in 1849, the property steadily fell into disrepair and a recent private restoration effort of the home, studio and grounds has seen renewed interest in the cultural significance of the region. With that in mind, and with Marathon a neighbouring property, participants in the project were able to experience the area and research its past and present as a part of a network of working properties, but also encouraging conversation around the region as a contested and documented place of settlement and subsequent violence toward the Aboriginal people. Marathon is a working property, yet also a vital and fragile ecosystem. Marathon consists of 1430 hectares, of which around 300 lowland hectares are currently used for sheep grazing. The paddocks retain their productivity, function and potential to return to native grassland, while thickets of gorse are plentiful, an example of an invasive species difficult to control. The rest of the property comprises eucalypt woodlands and native grasslands that have been protected under a conservation covenant by the landowners since 2003. The Marathon creek and the Nile River mark the boundary between the functional paddocks and the uncultivated hills and are actively managed in the interface between native and introduced species of flora and fauna. This covenant aimed to preserve these landscapes, linking in with a wider pattern of organisations and landowners attempting to address significant ecological degradation and isolation of remnant bushland patches through restoration ecology. Measured against the visibility of Tasmania’s wilderness identity on the national and global stage, many of the ecological concerns affecting the Midlands go largely unnoticed. The Marathon Project was as much a project about visibility and communication as it was about art and landscape. Over the three years and with its 17 participants, The Marathon Project yielded three major exhibitions along with numerous public presentations and research outputs. The length of the project and the autonomy and perspectives of its participants allowed for connections to be formed, conversations initiated, and greater exposure to the productivity and sustainability complexities playing out on rural Midland properties. Like Kerry Lodge, the 2015 first year exhibition took place at Sawtooth ARI. The exhibition was a testing ground for artists, and a platform for audiences, to witness the cross-disciplinary outputs of work inspired by a single sheep grazing farm. The interest generated led to the rethinking of the 2016 exhibition and the need to broaden the scope of what the landowners and participants were trying to achieve. Image 7: Panel Discussion at Open Weekend, 2016. Image Credit: Ron Malor.In November 2016, The Marathon Project hosted an Open Weekend on the property encouraging audiences to visit, meet the artists, the landowners, and other invited guests from a number of restoration, conservation, and rehabilitation organisations. Titled Encounter, the event and accompanying exhibition displayed in the shearing shed, provided an opportunity for a rhizomatic effect with the public which was designed to inform and disseminate historical and contemporary perspectives of land and agriculture, access, ownership, visitation and interpretation. Concluding with a final exhibition in 2017 at the University of Tasmania’s Academy Gallery, The Marathon Project had built enough momentum to shape and inform the practice of its participants, the knowledge and imagination of the public who engaged with it, and make visible the precarity of the cultural and rural Midland identity.Image 8. Installation View of The Marathon Project Exhibition, 2017. Image Credit: Patrick Sutczak.ConclusionThe Marathon Project, Species Hotel and the Kerry Lodge Archaeology and Art Project all demonstrate the potential of site-based projects to articulate and address concerns that arise from the environmental and cultural conditions and histories of a region. Beyond the Midland fence line is a complex environment that needed to be experienced to be understood. Returning creative work to site, and opening up these intensified experiences of place to a public forms a key stage in all these projects. Beyond a commitment to site-specific practice and valuing the affective and didactic potential of on-site installation, these returns grapple with issues of access, visibility and absence that characterise the Midlands. Paul Carter describes his role in the convening of a “concretely self-realising creative community” in an initiative to construct a meeting-place in Alice Springs, a community defined and united in “its capacity to imagine change as a negotiation between past, present and future” (17). Within that regional context, storytelling, as an encounter between histories and cultures, became crucial in assembling a community that could in turn materialise story into place. In these Midlands projects, a looser assembly of participants with shared interests seek to engage with the intersections of plant, human and animal activities that constitute and negotiate the changing environment. The projects enabled moments of connection, of access, and of intervention: always informed by the complexities of belonging within regional locations.These projects also suggest the need to recognise the granularity of regionalism: the need to be attentive to the relations of site to bioregion, of private land to small town to regional centre. The numerous partnerships that allow such interconnect projects to flourish can be seen as a strength of regional areas, where proximity and scale can draw together sets of related institutions, organisations and individuals. However, the tensions and gaps within these projects reveal differing priorities, senses of ownership and even regional belonging. Questions of who will live with these project outcomes, who will access them, and on what terms, reveal inequalities of power. Negotiations of this uneven and uneasy terrain require a more nuanced account of projects that do not rely on the geographical labelling of regions to paper over the complexities and fractures within the social environment.These projects also share a commitment to the intersection of the social and natural environment. They recognise the inextricable entanglement of human and more than human agencies in shaping the landscape, and material consequences of colonialism and agricultural intensification. Through iteration and duration, the projects mobilise processes that are responsive and reflective while being anchored to the materiality of site. Warwick Mules suggests that “regions are a mixture of data and earth, historically made through the accumulation and condensation of material and informational configurations”. Cross-disciplinary exchanges enable all three projects to actively participate in data production, not interpretation or illustration afterwards. Mules’ call for ‘accumulation’ and ‘configuration’ as productive regional modes speaks directly to the practice-led methodologies employed by these projects. The Kerry Lodge and Marathon projects collect, arrange and transform material taken from each site to provisionally construct a regional material language, extended further in the dual presentation of the projects as off-site exhibitions and as interventions returning to site. The Species Hotel project shares that dual identity, where materials are chosen for their ability over time, habitation and decay to become incorporated into the site yet, through other iterations of the project, become digital presences that nonetheless invite an embodied engagement.These projects centre the Midlands as fertile ground for the production of knowledge and experiences that are distinctive and place-based, arising from the unique qualities of this place, its history and its ongoing challenges. Art and design practice enables connectivity to plant, animal and human communities, utilising cross-disciplinary collaborations to bring together further accumulations of the region’s intertwined cultural and ecological landscape.ReferencesAustralian Government Department of the Environment and Energy.
