We present a novel approach to woven-cloth simu-lation in order to generate persistent wrinkles and folds. For a couple of decades, our community has identified and mimicked non-linear buckling of cloth based on the mechanical measure-ment of cloth. It has, however, scarcely paid attention to another important aspect of the measurement, the hysteresis of cloth be-haviors, which is the lag of the amount of forces between stress and relaxation. Our interpretation of the measurement indicates that persistent wrinkles and folds develop in part from the hyste-resis of cloth and its associated energy loss. Thus, we establish an adaptive energy model which takes stiffness coefficients and rest posture values not as constants but as variables over time and behavior. As stiffness coefficients and rest posture values change in proportion to the amount of the energy loss, they appear as persistent wrinkles and folds. Consequently, the clothes simulated by our method bring more realism with respect to visual identi-fication for past behaviors of cloth.

Over Time

In this paper, I undertake a novel approach to uncover the forecasting interconnections in the international housing markets. Using a dynamic model averaging framework that allows both the coefficients and the entire forecasting model to dynamically change over time, I uncover the intertwined forecasting relationships in 23 leading international housing markets. The evidence suggests significant forecasting interconnections in these markets. However, no country holds a constant forecasting advantage, including the United States and the United Kingdom, although the U.S. housing market's predictive power has increased over time. Evidence also suggests that allowing the forecasting model to change is more important than allowing the coefficients to change over time.

As it is appreciated that learning is a non-linear process – implying that coaching methodologies in sport should be accommodative – it is reasonable to suggest that player development pathways should also account for this non-linearity. A constraints-led approach (CLA), predicated on the theory of ecological dynamics, has been suggested as a viable framework for capturing the non-linearity of learning, development and performance in sport. The CLA articulates how skills emerge through the interaction of different constraints (task-environment-performer). However, despite its well-established theoretical roots, there are challenges to implementing it in practice. Accordingly, to help practitioners navigate such challenges, this paper proposes a user-friendly framework that demonstrates the benefits of a CLA. Specifically, to conceptualize the non-linear and individualized nature of learning, and how it can inform player development, we apply Adolph’s notion of learning IN development to explain the fundamental ideas of a CLA. We then exemplify a learning IN development framework, based on a CLA, brought to life in a high-level youth football organization. We contend that this framework can provide a novel approach for presenting the key ideas of a CLA and its powerful pedagogic concepts to practitioners at all levels, informing coach education programs, player development frameworks and learning environment designs in sport.

AbstractThe quantitative description of individual observations in non-linear mixed effects models over time is complicated when the studied biomarker has a pulsatile release (e.g. insulin, growth hormone, luteinizing hormone). Unfortunately, standard non-linear mixed effects population pharmacodynamic models such as turnover and precursor response models (with or without a cosinor component) are unable to quantify these complex secretion profiles over time. In this study, the statistical power of standard statistical methodology such as 6 post-dose measurements or the area under the curve from 0 to 12 h post-dose on simulated dense concentration–time profiles of growth hormone was compared to a deconvolution-analysis-informed modelling approach in different simulated scenarios. The statistical power of the deconvolution-analysis-informed approach was determined with a Monte-Carlo Mapped Power analysis. Due to the high level of intra- and inter-individual variability in growth hormone concentrations over time, regardless of the simulated effect size, only the deconvolution-analysis informed approach reached a statistical power of more than 80% with a sample size of less than 200 subjects per cohort. Furthermore, the use of this deconvolution-analysis-informed modelling approach improved the description of the observations on an individual level and enabled the quantification of a drug effect to be used for subsequent clinical trial simulations.

This article explores the role of remembering and history in the process of planning new spaces. We trace how the organizational remembering of past spaces enters the conception (i.e. planning) of a large culture center. By drawing on Henri Lefebvre’s reflections on history, time and memory, we analyze the processual interconnections of his spatial triad, namely between the planned, practiced, and lived moments of the production of space. We find that over time space planning involves recurrent, changing, and contested narratives on ‘lost spaces’, remembering happy spaces of the past that articulate a desire to regain them. The notion of lost space adds to our understanding of how space planning involves, through organizational remembering, a sociomaterial and spatiotemporal work of relating together different spaces and times in non-linear narratives of repetition.

Over Time

The pandemic caused by the corona virus has changed the lifestyle of humans, both directly and indirectly, especially generation Z in Jakarta. The way humans meet their primary needs also changes over time. Many of generation Z decide to shop online to meet their individual needs. Generation Z defines balance as one of the things that is seen in living life, including meeting their needs and interacting with others. The Future Market in Gondangdia exists as a forum that provides space for buying and selling transactions to be more interactive, creative, flexible, and in accordance with health protocols. Through dis-programming, combining creative buying and selling programs and public space as one unit in a design is one of the methods used in designing architectural programs. The combination of the two programs creates an equal space with alternate uses depending on time. The emerging market typology method and its relation to Z generation architecture and behavior become a design strategy in designing. This provides an innovative and interactive buying and selling space according to the needs of generation Z. Keywords: Buy and sell spaces; Public spaces; Future markets; Generation Z; Buy and sell; Dis-programming AbstrakPandemi yang disebabkan oleh virus korona telah mengubah gaya hidup manusia, baik secara langsung maupun tidak langsung, khususnya generasi Z di Jakarta. Cara manusia dalam memenuhi kebutuhan primernya pun berubah seiring berjalannya waktu. Banyak dari generasi Z memutuskan untuk berbelanja online untuk memenuhi kebutuhannya masing-masing. Generasi Z mendefinisikan keseimbangan sebagai salah satu hal yang dilihat dalam menjalani kehiduoan termasuk dalam memenuhi kebutuhannya dan berinteraksi dengan sesamanya. Melalui dis-programming memadukan program jual beli kreatif dan ruang publik sebagai satu kesatuan di dalam sebuah desain merupakan salah satu metodw yang digunakan dalam perancangan program arsitektur. Perpaduan kedua program tersebut menciptakan sebuah ruang yang sama dengan penggunaanya bergantian tergantung oleh waktu. Metode tipologi pasar yang berkembang dan kaitannya dengan arsitektur dan perilaku generasi Z menjadi strategi desain dalam merancang. Hal ini memberikan ruang jual beli yang inovatif dan interaktif sesuai dengan kebutuhan generasi Z.
