Purpose This study aims to explore the need for space (demand) and the provision thereof (supply) in the Faculty of Architecture building at Thammasat University Rangsit campus using variables from the designing an accommodation strategy (DAS) framework; these variables are incorporated to test and improve the framework. Another purpose is to examine the planning and development of the faculty building to understand its strategy, which serves as a means to contribute to the planning and development theory. Design/methodology/approach A case study of the Faculty of Architecture building was conducted at Thammasat University in Thailand. The DAS framework was used to reconstruct and examine the development process of the building to determine the gaps between supply and demand in terms of building space, to reflect on the building plan and process and to make suggestions as to how the DAS framework might be improved. Research methods included interviews and document analysis concerning space requirements and provision in the Faculty of Architecture building. Findings The gaps between supply and demand in terms of the faculty building space are affected by the condition of the building (i.e. building obsolescence), the number of building users and the changing environmental context. This study shows that both pre-design and post-occupancy evaluation are essential to collect data concerning the match or mismatch between supply and demand of space and to assess users’ needs and preferences concerning the faculty building. Regarding the building development process, factors impacting the step-by-step planning of the real estate interventions include the organisational context (public/private sector) and the management of the construction project (time, cost, quality). The DAS framework is found to be useful for structuring the information-generating processes necessary to determine gaps between demand and supply in terms of space and for making decisions regarding real estate interventions. Research limitations/implications Additional case studies in different environmental and organisational contexts are required to test the DAS framework and improve data validity. This study was conducted during the COVID-19 pandemic period, which affected data accessibility. Practical implications The results provide insight into the influence of various factors on the decision of corporate real estate. The DAS framework can be used to explore the range of demand for and supply of space and to find an optimal match. Originality/value This paper shows valuable steps in planning and development of educational real estate and a first application of the DAS framework in Thailand. The findings confirm the importance of the physical learning environment of architecture schools, particularly the studio spaces required in architecture education.

Fuzzy Preference

Purpose University department efficiency evaluation is a performance assessment on how departments use their resources to attain their goals. The most widely used tool in measuring the efficiency of academic departments in data envelopment analysis (DEA) deals with crisp data, which may be, often, imprecise, vague, missing or predicted. Current literature offers various approaches to addressing these uncertainties by introducing fuzzy set theory within the basic DEA framework. However, current fuzzy DEA approaches fail to handle missing data, particularly in output values, which are prevalent in real-life evaluation. Thus, this study aims to augment these limitations by offering a fuzzy DEA variation. Design/methodology/approach This paper proposes a more flexible approach by introducing the fuzzy preference programming – DEA (FPP-DEA), where the outputs are expressed as fuzzy numbers and the inputs are conveyed in their actual crisp values. A case study in one of the top higher education institutions in the Philippines was conducted to elucidate the proposed FPP-DEA with fuzzy outputs. Findings Due to its high discriminating power, the proposed model is more constricted in reporting the efficiency scores such that there are lesser reported efficient departments. Although the proposed model can still calculate efficiency no matter how much missing and unavailable, and uncertain data, more comprehensive data accessibility would return an accurate and precise efficiency score. Originality/value This study offers a fuzzy DEA formulation via FPP, which can handle missing, unavailable and imprecise data for output values.

Data Portal

As more ocean plans are developed and adopted around the world, the importance of accessible, up-to-date spatial data in the planning process has become increasingly apparent. Many ocean planning efforts in the United States and Canada rely on a companion data portal–a curated catalog of spatial datasets characterizing the ocean uses and natural resources considered as part of ocean planning and management decision-making.Data portals designed to meet ocean planning needs tend to share three basic characteris- tics. They are: ocean-focused, map-based, and publicly-accessible. This enables planners, managers, and stakeholders to access common sets of sector-speci c, place-based information that help to visualize spatial relationships (e.g., overlap) among various uses and the marine environment and analyze potential interactions (e.g., synergies or con icts) among those uses and natural resources. This data accessibility also enhances the transparency of the planning process, arguably an essential factor for its overall success.This paper explores key challenges, considerations, and best practices for developing and maintaining a data portal. By observing the relationship between data portals and key principles of ocean planning, we posit three overarching themes for data portal best practices: accommodation of diverse users, data vetting and review by stakeholders, and integration with the planning process. The discussion draws primarily from the use of the Northeast Ocean Data Portal to support development of the Northeast Ocean Management Plan, with additional examples from other portals in the U.S. and Canada.

Comparisons between biodiversity and other complex systems can facilitate cross-disciplinary exchange of theories and the identification of key system processes and constraints. For example, due to qualitative structural and functional analogies to biological systems, coupled with good data accessibility, computer operating systems offer opportunities for comparison with biodiversity. However, it remains largely untested if the two systems also share quantitative patterns. Here, we employ analogies between GNU/Linux operating systems (distros) and biological species, and look for a number of well-established ecological and evolutionary patterns in the Linux universe. We demonstrate that patterns of the Linux universe match the macroecological patterns: Linux distro commonness and rarity (popularity of a distro) follow a lognormal distribution, power law mean-variance scaling of temporal fluctuation, and there is a significant relationship between niche breadth (number of software packages) and commonness. The diversity in the Linux universe also follows general macroevolutionary patterns: The number of phylogenetic lineages increases linearly through time, with clear per-species diversification and extinction slowdowns, something that is unobservable in biology. Moreover, the composition of functional traits (software packages) exhibits significant phylogenetic signal. Our study provides foundations for using Linux as a model system for eco-evolutionary studies, as well as insights into patterns and dynamics of computer operating systems, which may be used to inform their future development and maintenance. The co-emergence of patterns across systems suggests that some patterns might be produced by system-level properties, independently of system identity, which offers an empirical argument for non-biological explanations of fundamental biodiversity patterns.

AbstractFor insect species in temperate environments, seasonal timing is often governed by the regulation of diapause, a complex developmental program that allows insects to weather unfavorable conditions and synchronize their lifecycles with available resources. Diapause consists of a series of phases that govern initiation, maintenance, and termination of this developmental pathway. The evolution of insect seasonal timing depends in part on how these phases of diapause development and post-diapause development interact to affect variation in phenology. Here, we dissect the physiological basis of a recently evolved phenological shift in Rhagoletis pomonella (Diptera: Tephritidae), a model system for ecological divergence. A recently derived population of R. pomonella shifted from specializing on native hawthorn fruit to earlier fruiting introduced apples, resulting in a 3-4 week shift in adult emergence timing. We tracked metabolic rates of individual flies across post-winter development to test which phases of development may act either independently or in combination to contribute to this recently evolved divergence in timing. Apple and hawthorn flies differed in a number of facets of their post-winter developmental trajectories. However, divergent adaptation in adult emergence phenology in these flies was due almost entirely to the end of the pupal diapause maintenance phase, with post-diapause development having a very small effect. The relatively simple underpinnings of variation in adult emergence phenology suggest that further adaptation to seasonal change in these flies for this trait might be largely due to the timing of diapause termination unhindered by strong covariance among different components of post-diapause development.Data accessibilityAll data (in the form of tables of all metabolic rate measurements for all individual flies in the study) will be available on DRYAD when the manuscript is published.

AbstractThermal performance curves (TPCs) are used to predict changes in species interactions, and hence range shifts, disease dynamics and community composition, under forecasted climate change. Species interactions might in turn affect TPCs. Here, we investigate whether temperature-dependent changes in a microbial host-parasite interaction (the bacterium Pseudomonas fluorescens, and its bacteriophage, SBWФ2) changes the host TPC. The bacteriophage had a narrower infectivity range, with their critical thermal maximum ∼6°C lower than those at which the bacteria still had high growth. Consequently, in the presence of phage, the host TPC had a higher optimum temperature and a lower maximum growth rate. These changes were driven by a temperature-dependent evolution, and cost, of resistance; the largest cost of resistance occurring where bacteria grew best in the absence of phage. Our work highlights how ecological and evolutionary mechanisms can alter the effect of a parasite on host thermal performance, even over very short timescales.Data accessibility statementAll data and R code used in the analysis will be made available on GitHub and archived on Zenodo.
