Full Simulation Data and Worked Examples from Specht et al. Conditional Occupancy Manuscript
No full textTo accompany publication of the conditional design for occupancy analysis, we provide the full simulation dataset used to compare the performance of standard, removal and conditional designs in common occupancy analysis programs: R package unmarked, Program MARK and PRESENCE.
Specht_etal_AS3_CondOcc_SimulationCode.R is an R script that was used to generate the simulation data in AS4_Specht_etal_SimulationData.csv. AS4_Specht_etal_SimDataSet_metadata.csv contains variable labels for columns in AS4_Specht_etal_SimulationData.csv, including additional calculated variables not generated from the simulations. PRESENCE_files_for_Specht_etal.zip, ProgramMARK_files_for_Specht_etal.zip and Unmarked_example_for_Specht_etal.R provide files to work through examples of conditional, standard and removal occupancy designs for the same case in Program MARK, Program PRESENCE and R package unmarked, respectively. These files allow users to compare estimation by each method in a case where true occupancy probability is 0.2 and true detection probability is 0.5, and provide examples of formatted data input files. See Readme_Specht_etal.txt for more details.Occupancy models are widely used to describe the distribution of rare and cryptic species— those that occur on only a portion of the landscape and cannot be detected reliably during a single survey. However, occupancy models often provide inaccurate estimates of occupancy (ψ ̂) and detection probabilities (p ̂) under these circumstances. We developed a new "conditional" occupancy design that more accurately estimates occupancy for rare species. Here we provide the full simulation dataset used to compare estimation properties of standard, removal and conditional designs. Data were simulated in R and analyzed using MCMC methods in package R2jags. See Specht et al. (in review) for description of methods.

Lutie May Specht
No full text1911-1912 scrapbook of Lutie May Specht (attended 1911-1912). Specht had a sister who attended Hollins College in 1910-1911 which might explain why one or more of the photos are dated \u271910\u27. Photos include students and faculty, Hollins buildings and scenery.https://digitalcommons.hollins.edu/scrapbooks/1038/thumbnail.jp
Hans Joachim Specht
No full textThis open access book celebrates the extraordinary lifetime achievements of Professor Hans Joachim Specht, a visionary scientist whose passion for interdisciplinary research has left an indelible mark on science and society. By seamlessly merging diverse fields, Specht demonstrated how curiosity, vision, and diversity can drive groundbreaking innovation and create lasting societal impact. Unlike conventional scientific biographies that often focus on a single discipline, this book highlights Specht’s remarkable ability to bridge atomic physics, nuclear fission, ultra-relativistic heavy-ion physics, and pioneering contributions to hadron cancer therapy. The chapters cover topics such as Specht's pivotal role in developing hadron cancer therapy from fundamental heavy-ion research, his transformative work in bridging nuclear physics and medicine, and his leadership in establishing Europe's first Hadron Cancer Therapy Center. Readers will discover how Specht's interdisciplinary curiosity extended to the intersections of music, physics, and neuroscience, producing influential publications in prestigious journals and delivering lectures at world-renowned institutions. His story illustrates how cross-disciplinary approaches fuel breakthroughs that extend beyond academia to benefit humanity. The book is a must-read for scientists aspiring to leadership roles in science management and policy. Specht’s visionary leadership exemplifies the ability to make challenge-based decisions that drive progress while addressing societal needs. Through real-life anecdotes, readers gain insights into fostering collaboration, mentoring young scientists, cultivating teamwork, and making strategic decisions for a sustainable future. Scholars, researchers, and students across the disciplines of physics, medicine, and interdisciplinary studies will find invaluable lessons in Specht’s dedication to teaching, mentoring, and inspiring others. More than a tribute, it calls future generations to embrace interdisciplinary approaches, pursue socially relevant science, and lead with vision

A Specht filtration of an induced Specht module
No full textAbstractLet Hn be a (degenerate or non-degenerate) Hecke algebra of type G(ℓ,1,n), defined over a commutative ring R with one, and let S(μ) be a Specht module for Hn. This paper shows that the induced Specht module S(μ)⊗HnHn+1 has an explicit Specht filtration

An Analysis of the Educational Potential of Augmented Reality Games for Learning
No full textSchmitz, B., Specht, M., & Klemke, R. (2012). An Analysis of the Educational Potential of Augmented Reality Games for Learning. In M. Specht, J. Multisilta, & M. Sharples (Eds.), Proceedings of the 11th World Conference on Mobile and Contextual Learning 2012 (pp. 140-147). October, 16-18, 2012, Helsinki, Finland.This paper presents a review of practical research papers on augmented reality games for learning. The study evaluates how these games may impact motivation (affective learning outcomes) and knowledge gain (cognitive learning outcomes). For the analysis, we use game design patterns for mobile games and Bloom’s taxonomy of educational objectives. Our study results substantiate the generally assumed motivational potential of augmented reality games. Also, they indicate that augmented reality games may have the potential to bring about cognitive learning outcomes
Ambient Learning Displays: lecture series and results from a participatory design study
No full textBörner, D., Kalz, M., & Specht, M. (2012). Ambient Learning Displays: lecture series and results from a participatory design study. In M. Specht, J. Multisilta, & M. Sharples (Eds.), Proceedings of the 11th World Conference on Mobile and Contextual Learning 2012 (pp. 232-235). October, 16-18, 2012, Helsinki, Finland.Emerging from pervasive and mobile technologies, ambient displays present information and media in the periphery of the user. Thereby the displays situated and interacting in the close proximity are an addition to existing personal interfaces in the foreground, while the user attention can always move from one to the other and back. Especially the ability to deliver contextualised and personalised information in authentic situations fosters ambient displays as an instrument for learning. However the actual design of ambient displays for learning proves to be difficult, as the technical implementations as well as the underlying instructional principles are still immature. The paper presents the main constituents of a lecture series on the use of ambient displays for learning and a first participatory design study conducted during two consecutive lecture sessions. The results show a variety of usable ambient display types, possible learning scenarios, and specific design proposals towards ambient learning displays
Decomposable Specht modules indexed by bihooks II
No full textPreviously, the last two authors found large families of decomposable Specht
modules labelled by bihooks, over the Iwahori--Hecke algebra of type . In
most cases we conjectured that these were the only decomposable Specht modules
labelled by bihooks, proving it in some instances. Inspired by a recent
semisimplicity result of Bowman, Bessenrodt and the third author, we look back
at our decomposable Specht modules and show that they are often either
semisimple, or very close to being so. We obtain their exact structure and
composition factors in these cases. In the process, we determine the graded
decomposition numbers for almost all of the decomposable Specht modules indexed
by bihooks.Comment: 33 pages, comments are welcome. v2 is the final version, to appear in

A family of modules with Specht and dual Specht filtrations
No full textWe study the permutation module arising from the action of the symmetric group S-2n, on the conjugacy class of fixed-point-free involutions, defined over an arbitrary field. The indecomposable direct summands of these modules are shown to possess filtrations by Specht modules and also filtrations by dual Specht modules. We see that these provide counterexamples to a conjecture by Hemmer. Twisted permutation modules are also considered, as is an application to the Brauer algebra
