Abstract Evelyn Tucker, a Monuments, Fine Arts, and Archives (MFA&A) representative, worked in the US military–occupied zone of Austria, investigating and restituting Nazi-plundered, Austrian-owned cultural property between 1946 and 1949. Her experiences remain hidden despite passing references in the scholarship covering Allied restitution of Nazi-looted, Jewish-owned cultural property, as the literature focuses on postwar Germany, not Austria. She attempted to openly criticize the US Army for the thefts by blaming the Army’s appalling behavior on its lack of understanding US restitution efforts. However, she was incapable of stopping this gross negligence, and her condemnation of the Army led to her dismissal. I argue that contentious political divisions within the Allies’ policymaking in occupied Austria stalled Tucker’s restitution investigations, thus her work deserves critical investigation. Tucker defied expectations, and a thoughtful analysis of her contributions to the restitution process helps us gain a clearer appreciation of the political and cultural chaos of occupied Austria. In relationship to that gap, my archival research sheds light on the underappreciated role of Eve Tucker in her fight for rightful restitution.

Artykuł stanowi przypomnienie innowatorów i wynalazców, którzy przegrali walkę z wielkimi korporacjami. Autor skupia się na dwóch takich przypadkach: Edwinie Howardzie Armstrongu – wynalazcy superheterodyny i odkrywcy możliwości nadawania programów radiowych na falach FM, oraz Prestonie Thomasie Tuckerze – konstruktorze nowatorskiego samochodu, o którym Francis Ford Coppola zrobił film Tucker – konstruktor marzeń (1988). Podobny los spotkał też Barthélemy’ego Thimonniera – wynalazcę maszyny do szycia, a nawet kilku pionierów kina, którzy nie zdążyli w porę opatentować swoich wynalazków, m.in. Louis Aimé Augustina Le Prince’a.

This paper studies the characterizations of (weakly) Pareto-Nash equilibria for multiobjective population games with a vector-valued potential function called multiobjective potential population games, where agents synchronously maximize multiobjective functions with finite strategies via a partial order on the criteria-function set. In such games, multiobjective payoff functions are equal to the transpose of the Jacobi matrix of its potential function. For multiobjective potential population games, based on Kuhn-Tucker conditions of multiobjective optimization, a strongly (weakly) Kuhn-Tucker state is introduced for its vector-valued potential function and it is proven that each strongly (weakly) Kuhn-Tucker state is one (weakly) Pareto-Nash equilibrium. The converse is obtained for multiobjective potential population games with two strategies by utilizing Tucker’s Theorem of the alternative and Motzkin’s one of linear systems. Precisely, each (weakly) Pareto-Nash equilibrium is equivalent to a strongly (weakly) Kuhn-Tucker state for multiobjective potential population games with two strategies. These characterizations by a vector-valued approach are more comprehensive than an additive weighted method. Multiobjective potential population games are the extension of population potential games from a single objective to multiobjective cases. These novel results provide a theoretical basis for further computing (weakly) Pareto-Nash equilibria of multiobjective potential population games and their practical applications.

John Tucker was a member of Parliament for the borough of Weymouth between 1735–47 and again between 1754–78. The relevant entries for him in the volumes of the History of Parliament are exiguous. He appears to have made only two interventions in Commons debates, on 27 February 1771 and 30 April 1772. In John Brooke's words, both were “slight and short.” According to the History of Parliament, Tucker's political stance was determined largely by his relationship with George Bubb Dodington, although the evidence is capable, as we shall see, of being read in a different way. Romney Sedgwick quotes from a letter Dodington wrote to Sir Robert Walpole in 1737, following the famous division on the Prince of Wales's allowance, that “the connexion between these gentlemen [those identified with his interest, including Tucker] and me was such that we should not have differed in opinion” even had he decided to vote for the motion. Tucker emerges from the History of Parliament volumes as a man without political views of his own and as an individual tightly caught up in a politics shaped principally by interest and management.This article exploits a hitherto neglected source to reconstruct more fully John Tucker's political world and views, to present a different account of his political stance and importance, and thus to throw considerable light on politics in the mid-eighteenth century. This source is a manuscript collection that the Bodleian Library acquired in 1969 and 1970. The collection mostly comprises the papers of John Tucker's father, Edward, his brother, Richard, and John himself.

Mój komentarz do książki Aviezera Tuckera dotyczy czterech kwestii, które Francis Fukuyama definiuje jako cztery poziomy, na których musi zachodzić konsolidacja demokracji: 1. Ideologia, 2. Instytucje, 3. Społeczeństwo obywatelskie i 4. Kultura. Książka Tuckera dostarcza wnikliwej analizy roli odgrywanej przez każdą z tych sfer w postkomunistycznym społeczeństwie. Badając wnikliwie dziedzictwo totalitaryzmu, Tucker dochodzi do wniosku, że totalitaryzm nie jest martwy i częściowo przynajmniej powraca. Aby się przed nim obronić, proponuje on proste rozwiązanie: powrót dysydentów. Nowi neo-dysydenci mogą zbawić swoje posttotalitarne społeczeństwa od nienawiści, kłamstw i płytkiego pragmatyzmu poprzez miłość, prawdę i osobistą integralność. Musimy niestety nieco poczekać, aby przekonać się, czy propozycja Tuckera jest skuteczna.

We introduce some concepts of generalized invexity for the continuous-time multiobjective programming problems, namely, the concepts of Karush-Kuhn-Tucker invexity and Karush-Kuhn-Tucker pseudoinvexity. Using the concept of Karush-Kuhn-Tucker invexity, we study the relationship of the multiobjective problems with some related scalar problems. Further, we show that Karush-Kuhn-Tucker pseudoinvexity is a necessary and suffcient condition for a vector Karush-Kuhn-Tucker solution to be a weakly efficient solution.

Regional Economic Voting: Russia, Poland, Hungary, Slovakia and the Czech Republic, 1990–1999, Joshua A. Tucker, New York: Cambridge University Press, 2006, pp. xxii, 417.Recognizing and predicting the patterns of voting behaviour is a formidable task even in the case of mature and stable democracies. Needless to say, the identification of such trends in the wake of a fundamental political and economic restructuring, when the basic rules of the game are still in flux, can be frustratingly elusive. In this ambitious and methodologically sophisticated study, Joshua Tucker takes on the challenge and suggests a fresh approach for cutting through the fog of post-communist institutional ambiguity. The book reports on several prominent regularities in the voting outcomes that span five countries, several distinct institutional designs, twenty national elections and ten years of transition. In contrast to the studies that rely on micro-level survey data or small-n cross-country comparisons, Tucker aggregates and analyzes the election results at the intermediate, regional level. Cross-regional comparison provides enough resolution for detecting systematic voting patterns shaped by local economic conditions. Explaining the observed connection between regional economy and regional vote is the central theme of Tucker's study.

Let me begin by thanking Jim Tucker for offering his thoughts on my JSE paper on the James Leininger case (Sudduth 2021). I appreciate his clarifying his interpretation of several of the facts in the case, as well as his providing further context to some of them. I also appreciate his acknowledgement of Bruce Leininger’s authorship of the 2003 chronology which I uncovered in my investigation and made use of in my paper. That’s all helpful. For the rest, I wish I could say what St. Augustine said to Evodius when responding to the latter’s criticisms – “you have knocked vigorously.” Alas, I cannot say this about Tucker’s response. My paper developed a number of different concerns about the evidential value of the James Leininger case (hereafter, JL case). The paper was lengthy and the scope of the material I presented was broad, often involving considerable detail regarding different aspects of the case. I realize this can make writing a concise and salient response a daunting task. To effectively navigate the landscape, therefore, it’s crucial to properly understand the structure and content of my arguments, as well as how I intend to leverage various facts in the service of specific lines of argument. One must not miss the forest (the argument) for the trees (particular facts). Or, in the words of St. Augustine, one must knock vigorously. Tucker has not.

Autor stwierdza, że praca TuckeramThe Legacies of Totalitarnianism jest niezmiernie ważna dla studiów nad postkomunizmem w Europie Środkowej i Wschodniej oraz dla historiozofii, która od czasów poheglowskich stroniła od holizmu. Zdaniem autora, Tucker trafnie identyfikuje ponadnarodowe składowe wspólnej tożsamości regionu, wynikające z tytułowych „dziedzictw” (procesów średnioterminowych wywodzących się z komunizmu). Badacz zauważa jednak, że nietrafność części prognoz Tuckera na podstawie jego własnej teorii wynika z nieuwzględnienia pewnych prawideł socjopsychologicznych i procesów długoterminowych.

There is a increasing interest in analysis of large-scale multiway data. The concept of multiway data refers to arrays of data with more than two dimensions, that is, taking the form of tensors. To analyze such data, decomposition techniques are widely used. The two most common decompositions for tensors are the Tucker model and the more restricted PARAFAC model. Both models can be viewed as generalizations of the regular factor analysis to data of more than two modalities. Nonnegative matrix factorization (NMF), in conjunction with sparse coding, has recently been given much attention due to its part-based and easy interpretable representation. While NMF has been extended to the PARAFAC model, no such attempt has been done to extend NMF to the Tucker model. However, if the tensor data analyzed are nonnegative, it may well be relevant to consider purely additive (i.e., nonnegative) Tucker decompositions). To reduce ambiguities of this type of decomposition, we develop updates that can impose sparseness in any combination of modalities, hence, proposed algorithms for sparse nonnegative Tucker decompositions (SN-TUCKER). We demonstrate how the proposed algorithms are superior to existing algorithms for Tucker decompositions when the data and interactions can be considered nonnegative. We further illustrate how sparse coding can help identify what model (PARAFAC or Tucker) is more appropriate for the data as well as to select the number of components by turning off excess components. The algorithms for SN-TUCKER can be downloaded from Mørup (2007).

Abstract A traditional proposition in the philosophy and the sociology of science wants that consensus between specialists of a scientific discipline is a reliable indicator of their access to genuine knowledge. In an interesting reassessment of this principle, Aviezer Tucker has analyzed the implications and the significance of this thesis in relation to historical research, and has established that parts of the historiographical community that display high degrees of consensus among their practitioners can be described in terms of the same relationship existing in empirical sciences between the exemplification of significant level of agreement and shared knowledge. After a concise summary of Tucker’s general view of the relationship between consensus and knowledge and an analysis of its discussion by Boaz Miller, this paper proposes a critical discussion of the limits and the virtues of this approach and concludes that it is possible to assume that a theory of the sort outlined by Tucker and Miller may describe in an exhaustive way the dynamics of the consensual communities only after some important caveats and integrations. In the closing section, a brief review of Tucker’s picture of historiographical consensus will be proposed.

The problem of missing data in multiway arrays (i.e., tensors) is common in many fields such as bibliographic data analysis, image processing, and computer vision. We consider the problems of approximating a tensor by another tensor with low multilinear rank in the presence of missing data and possibly reconstructing it (i.e., tensor completion). In this paper, we propose a weighted Tucker model which models only the known elements for capturing the latent structure of the data and reconstructing the missing elements. To treat the nonuniqueness of the proposed weighted Tucker model, a novel gradient descent algorithm based on a Grassmann manifold, which is termed Tucker weighted optimization (Tucker-Wopt), is proposed for guaranteeing the global convergence to a local minimum of the problem. Based on extensive experiments, Tucker-Wopt is shown to successfully reconstruct tensors with noise and up to 95% missing data. Furthermore, the experiments on traffic flow volume data demonstrate the usefulness of our algorithm on real-world application.

As a happy owner of the popular SEG monographs by Tucker and Yorston (1973) and Tucker (1982), the appearance of Tucker (1988) as the leadoff article in the June, 1988 issue of Geophysics caught my attention, and I began reading with high expectations. Admitting that the paper was chiefly about the philosophy and mechanics of contouring seismic data, I nevertheless found it disappointing, primarily because in describing his unique seismic contouring skill, Tucker never mentions migration or its importance in the conversion of raw seismic times to three‐dimensional (3-D) geologic structure. Also, many of the statements in his paper can be challenged on the grounds of imprecision or omission in terms of real structural interpretation.

Artykuł jest krytycznym komentarzem do książki Aviezera Tuckera The Legacies of Totalitarianism: A Theoretical Framework, która przedstawia koncepcję ewolucji totalitarnego komunizmu i jego transformacji oraz wynikającą stąd analizę problemów posttotalitarnych społeczeństw Europy Środkowo-Wschodniej. Zdaniem autora tekstu, choć omawiana książka jest nader rzadką próbą syntetycznego wyjaśnienia zarówno genezy systemu realnego socjalizmu, jak i jego transformacji, to Tucker przyjmuje zbyt wąskie pojmowanie klasy i interesu klasowego, co prowadzi do idealistycznej interpretacji czystek stalinowskich i wyłącznie instytucjonalistycznego pojmowania transformacji. Takie spojrzenie na transformację ustrojową nie pozwala osadzić jej ekonomicznych wymiarów w szerszej społecznej perspektywie.

Flair and Loathing on the Front Page, by Jim Tucker. New Plymouth, NZ: Jim Tucker Media. 2022, 283 pages. 'NAMES make news' is a mantra drummed into the head of every young reporter and heaven help those who can’t identify a vital quote or face. It is a lesson that veteran journalist and educator Jim Tucker never forgot. The evidence of that lies in the pages of Flair and Loathing on the Front Page, the first part of his memoir spanning a career that began in Taranaki in 1965 and which has gone full circle. Tucker is a regular columnist on the Taranaki Daily News after serving as a metropolitan newspaper reporter and editor then becoming one of New Zealand’s foremost journalism trainers.

The theory of mathematical programming widely spread as a method of a solution of extreme problems. It accompanies the study of plastic theory problem from its posing up to final solution. However, here again from our point of view not all possibilities are realized. Unfortunately, the use of mathematical programming as an instrument of a numerical solution for structural analysis frequently is also restricted by that. The possibilities of mechanical interpretation of optimality criteria of applied algorithms are not uncovered. The global solution of the problem of mathematical programming exists, if Kuhn-Tucker conditions are satisfied. These conditions do not depend on the applied algorithm of a problem solution. The identity of Kuhn-Tucker conditions with a optimality criteria of Rosen algorithm is finding out in this research. The role of a design matrix for the creating of strain compatibility equations is clarified. The Kuhn-Tucker conditions mean the residual strain compatibility equations in analysis of elastic-plastic systems. It is proved in the article that for problems of limiting equilibrium the Kuhn-Tucker conditions include the dependences of the associated law of plastic flow. The Kuhn-Tucker conditions together with limitations of a source problem of account represent a complete set of dependences of the theory of shakedown. The correct mathematical and mechanical interpretation of the Kuhn-Tucker conditions allows to refuse a direct solution of a dual problem of mathematical programming. It makes easier the solution of optimization problems of structures at shakedown.

We examined the sampling variability and capture efficiency of bongo nets and a modified Tucker trawl used in the sampling of ichthyoplankton and other macrozooplankton by taking seven replicate samples at each of two stations on two separate occasions. Sample variance was highly significantly related to sample mean for all major taxonomic categories (i.e., fish eggs, fish larvae, crustaceans, and medusae-chaetognaths). Sampling variability of the bongo nets was significantly greater than that of the Tucker trawl for both fish eggs and larvae. Sampling variability of macrozooplankton was significantly greater than that of ichthyoplankton. For larval fish of 5 mm or less, bongo nets generally yielded higher estimates of abundance than the Tucker trawl and the reverse was true for lengths above 10 mm, but there was a significant influence of species-specific morphological characters. The large sample volume of the Tucker trawl relative to the bongo nets resulted in significantly higher estimates of species diversity for fish eggs and larvae but not for crustaceans or medusae. Although bongo and Tucker samplers are efficient at catching a wide range of sizes of larval fish, the latter's lower variability may make it a more effective sampler.

Mój komentarz dotyczy oceny wpływu totalitarnego, komunistycznego dziedzictwa na system edukacji. Zostało to przeprowadzone w jednym z rozdziałów książki Aviezera Tuckera, The Legacies of Totalitarianism. Według niego głównym dylematem posttotalitarnego uniwersytetu jest odpowiedź na pytanie,czy celem fundamentalnej restrukturyzacji szkolnictwa wyższego jest osiągnięcie autonomii, czy zagwarantowanie sobie poparcia państwa poprzez symulację zmiany. Tucker twierdzi, że system boloński oznacza transformację uniwersytetów w zarządzane przez państwo korporacje, które obniżają standardy nauczania i wprowadzają różne mechanizmy mierzenia aktywności naukowej. Autor przekonująco argumentuje, że nieintecjonalnym efektem przystąpienia byłych krajów komunistycznych do Unii Europejskiej jest powrót do znanego w okresie komunizmu modelu symulowania zmian w szkolnictwie wyższym.

Remote sensing satellite images in the optical domain often contain missing or misleading data due to overcast conditions or sensor malfunctioning, concealing potentially important information. In this paper, we apply expectation maximization (EM) Tucker to NDVI satellite data from the Iberian Peninsula in order to gap-fill missing information. EM Tucker belongs to a family of tensor decomposition methods that are known to offer a number of interesting properties, including the ability to directly analyze data stored in multidimensional arrays and to explicitly exploit their multiway structure, which is lost when traditional spatial-, temporal- and spectral-based methods are used. In order to evaluate the gap-filling accuracy of EM Tucker for NDVI images, we used three data sets based on advanced very-high resolution radiometer (AVHRR) imagery over the Iberian Peninsula with artificially added missing data as well as a data set originating from the Iberian Peninsula with natural missing data. The performance of EM Tucker was compared to a simple mean imputation, a spatio-temporal hybrid method, and an iterative method based on principal component analysis (PCA). In comparison, imputation of the missing data using EM Tucker consistently yielded the most accurate results across the three simulated data sets, with levels of missing data ranging from 10 to 90%.

Long-day photoperiods of 16 h light (L) and 8 h dark (D) stimulate a proportional increase in live-weight (LW) gain of peripubertal Holstein heifers of 0·08 to 0·17 compared with heifers exposed to short days of less than 12 h L per day (Peters, Chapin, Leining and Tucker, 1978; Peters, Chapin, Emery and Tucker, 1980; Petitclerc, Chapin, Emery and Tucker, 1983; Zinn, Chapin and Tucker, 1986). One factor that could account for some of this variation in the magnitude of the growth response to long days is that the previous photoperiod exposure may influence the response to a subsequent different photoperiod (Moore-Ede, Sulzman and Fuller, 1982). For example, exposure to 13L: 11D induced pulsatile activity of serum luteinizing hormone (LH) in ewes previously exposed to 16L: 8D, but reduced serum LH to undetectable levels in sheep previously exposed to 8L: 16D (Robinson and Karsch, 1987). Thus, sheep exposed to identical photoperiods exhibited different responses depending on previous photoperiod exposure.
