THE SPARTAN SCHOOL OF INSTITUTIONAL ECONOMICS AT MICHIGAN STATE UNIVERSITY
Heterodox scholarship at Michigan State University (MSU) was influenced by the institutional economics of John R. Commons at Wisconsin. But it was far from monolithic and had many other sources and originality of its own. A case can be made that the center of institutional economics moved across Lake Michigan from Madison to East Lansing and blossomed in the second half of the 20th century with such Wisconsin Ph.D's as Raleigh Barlowe, Warren Samuels, Allan Schmid, Harry Trebing, and others. Equally important in making MSU a center of institutional economics were scholars from other institutional backgrounds such as Paul Strassmann, economic development; Robert Solo, science and technology; James Shaffer, agricultural marketing and consumer behavior; Nicholas Mercuro, law and economics; and others.Institutional and Behavioral Economics,
Didineis mokrousovi Schmid-Egger 2022, sp. nov.
Didineis mokrousovi Schmid-Egger, sp. nov. (Figs 1–8) Holotype. ♁, United Arab Emirates, Wadi Bih (dam), 19.i.2010, leg. AvH (CSE). Paratypes: 1 ♁, 4.iv.2009, 1♀, 29.xi.2009. 1♀, 11.ii.2010, 1♀, 2.v.2006, all Wadi Bih (dam); ♀, 29.xi.2009, Al Wathba Wetland Reserve; 1 ♁ 1 ♀, 22.06.2019, Al Bida’a Protected Area, all leg. AS &AvH, in Malaise traps (CSE). Remark: In former reviews of Crabronidae from the UAE (Schmid-Egger, 2011, 2014), specimens of Didineis from Wadi Bih were identified as D. bucharica with the key of Nemkov (2015). In the meantime, we could examine two males and two females of true D. bucharica from Russia, Kalmykia (see Mokrousov et al. (2016) for location and discussion of species). The specimens from the UAE differ in some important details from the Russian specimens, and belong to an undescribed species. A male was choosen as the holotype, because the description of D. bucharica is also based on a male. D. bucharica is restricted in its distribution to southern Russia (Dagestan, Kalmykia and Orenburg Prov.) and to Uzbekistan. Diagnosis. Males of both species are characterized by short and thick flagellomeres, flagellomere I beeing emarginate below. Remaining species have longer and normally rounded flagellomeres. Females of both species have also short and thick flagellomeres, but they share this character with other species from North Africa. See also Nemkov (2015) for further details. For distincion of D. bucharica and D. mokrousovi, see Table 1. . Description of male, holotype (copied and modified from description in Schmid-Egger, 2011). Body length 6 mm. Colour: Black, yellow are: basal 2/3 of mandible, clypeus, large band on inner eye margin, ending in upper 2/3, scape and flagellum below, AS 13, pronotal lobe, basal spot on basal sclerite of forewing. Femora and tibiae reddish, tarsi partly reddish, mostly brown. Wing venation brown, forewing greyish with some darker parts below stigma. Tergum I except base and tergum II laterally red, remaining terga black, last tergum apically somewhat reddish. Morphology: Apical clypeal margin slightly emarginate medially. Flagellum see Figs 2 and 3. Frons, pronotum, mesonotum and upper half of mesopleuron finely punctate, punctures 1–3 diameters apart, interspaces shiny. Punctuation of lower frons very dense. Lower mesopleuron rugulose-punctate. Propodeal surface evenly striate, propodeal enclosure triangular, surrounded by fine keel. Propodeum laterally and on backside rugulose. Terga II–V: basally shiny and with very fine micropunctation, apically punctate with shiny interspaces. Tergum VII densely punctate, apically truncate. Description of female: Body length 8.0 mm. Colour. Black, yellow are basal 2/3 of mandible, clypeus except for basal and lateral margin, narrow band along lower half of inner eye margin, scape below, last tarsomeres. Red are fore tibia, outer side of mid tibia, terga and sternum I and II, tergum II with black apical margin, apex of tergum VI. Wings as in male. Morphology: Flagellum: see fig. 6. Punctuation of head and thorax similar as in male, but much denser. Terga I and II shiny, impunctate, terga III–V similar as in male. Tergum VI in apical half surrounded by keel, forming a large pygidial plate with dense punctuation in apical half and with dense reddish setae. All femora below with long pale setae (2/3 as long as femoral diameter). Distribution. United Arab Emirates. Etymology. The species is dedicated to Mikhail Mokrousov from Nizhny Novgorod, Russia, a specialist of Aculeata, who kindly supported this and other projects of the author by sending specimens and information.Published as part of Schmid-Egger, Christian & Harten, Antonius Van, 2022, Additions to the digger wasps (Hymenoptera, Spheciformes) of the United Arab Emirates with description of ten new species, pp. 543-575 in Zootaxa 5219 (6) on pages 544-546, DOI: 10.11646/zootaxa.5219.6.3, http://zenodo.org/record/743623
The elusive author: found photography, authorship and the work of Joachim Schmid. In: Joachim Schmid photoworks 1982-2007
Joachim Schmid began his career in the early 1980s as a freelance critic and the publisher of Fotokritik, an iconoclastic and original contribution to West German photography. In the pages of Fotokritik and in his regular articles and lectures for other venues, Schmid argued articulately and at times vehemently against prevailing, predominantly conservative notions of art photography and in favour of a broad, encompassing critique of photography as a form of cultural practice. After ceasing publication of Fotokritik in 1987, Schmid focused on his own art production, based primarily on found photography and public image sources
The impact of alkyl- and alkoxy-functionalization on the responsive behaviour of metal-organic frameworks: from conventional to frustrated flexibility
The investigation of functional materials, which can change their physical properties depending on external triggers is of ongoing interest for various fields of materials research. Metal-organic frameworks (MOFs) are porous coordination polymers constructed of inorganic building units (e.g., metal-ions, metal-oxo-clusters) joined by organic building units (e.g., multidentate carboxylates), also called linkers. A particular subclass of MOFs are flexible MOFs, which undergo structural changes as a function of external stimuli. This behaviour arises from a delicate balance between enthalpic (e.g., dispersion interactions) and entropic (e.g., vibrational motions) contributions, which can be modified and controlled by the introduction of additional functional groups at the organic building unit of the framework.
In this work, alkyl-, alkoxy-, and methoxy-alkoxy group functionalization of the organic building unit was utilized to modulate and study the influence of sidechain length and polarity on the structural responsivity of two fundamentally different MOF platforms. Of these, one is intrinsically flexible (DMOF-1), while the other one is structurally rigid (MOF-5).
For the DMOF-1-based materials, it has been shown in the past that the implementation of alkoxy groups induces a guest- and temperature-depending switching between contracted and expanded phases. In this work, a series of purely alkyl-functionalized DMOF-1 derivatives was studied and structurally characterized in great detail by means of single crystal and powder X-ray diffraction. Furthermore, their sorption behaviour towards N2, CO2 and C3 and C4 hydrocarbons was investigated and subsequently compared to their alkoxy counterparts, which revealed significant differences that strongly relate to the different polarities of the functional groups. Particular highlights are path-depending multi-step CO2 sorption behaviours and an interesting propane/propylene gating behaviour with potential for an application in the separation of the gases, both phenomena were studied by in-situ X-ray diffraction techniques. Upon thermal treatment, the new alkyl functionalized DMOF-1 derivatives exhibit a significantly softer behaviour than their alkoxy counterparts indicating a much flatter free energy landscape for these materials in connection with weaker intra-framework interactions of the less polar alkyl groups.
In the second part of this thesis, the concept of frustrated flexibility of MOFs is introduced. Due to the incompatibility of a rigid, non-responsive MOF structure type (here MOF-5) with intra-framework dispersion forces demanding a densification of the structure a new type of responsive behaviour evolves. Controlled by chemical functionalization of the organic linkers with dispersion energy donating (DED) alkoxy groups, a series of materials is obtained, which reversibly switch between a cubic crystalline and either a non-crystalline or a rhombohedral phase. These transitions are either driven enthalpically through guest adsorption/desorption or by vibrational entropy at elevated temperatures. Importantly, frustratedly flexible behaviour is shown to be tuneable by adjusting the length and polarity of the DED groups.
Overall, the results presented herein demonstrate that linker functionalization is a powerful tool to modulate the free energy landscape of MOF materials. For intrinsically flexible MOFs this approach allows targeted fine-tuning of their flexible behaviour, while for rigid MOFs it allows for the generation of completely new and exotic responsive behaviour
Wolf Schmid se kommunikasiemodel as basis vir die dualiteitsbegrip: abstrakte auteur as wesens- en digterspersoonlikheid.
In this article Wolf Schmid\u27s model of communication as propounded in Der Textaufbau in den Erzahlungen Dostoevskijs is used as a basis for a new thesis as regards the concept abstract author. Schmid\u27s model comprises three elements: the author, the work of art as sign and the reader. This article holds that the duality implied in Schmid\u27s term "psychophysischen Dichterpersonlichkeit" should also be made applicable to the concept of the abstract author, regarded by Schmid as the hypostasised image of the author in his text. In this way a very useful distinction can be made between the abstract author as self as he reveals himself in a factual text (autobiography) and the abstract author as "poet" who, operating from the realm of the imagination, produces a fictive text(novel). In its published form, however, the "story text" in the book is preceded by the "writer\u27s text", which is ascribed to the abstract author as self, who "focalizes" or "interprets" what is to follow (e.g. by means of subtitle, motto or titles of chapters). Thus the "writer\u27s text" provides the link between "person" (self) and "poet".
Opsomming In hierdie artikel word Schmid se kommunikasiemodel soos aangebied in Der Textaufbau in den Erzahlungen Dostoevskijs as basis gebruik vir \u27n nuwe tese aangaande die begrip abstrakte outeur. Schmid se model maak voorsiening vir die outeur, die kunswerk as taalteken en die leser. Daar word uitgegaan van die standpunt dat die dualiteit onderliggend aan Schmid se opvatting van die konkrete outeur as \u27n "psycho-physischen Dichterpersonlichkeit" ook van toepassing gemaak behoort te word op die begrip abstrakte outeur, deur horn beskou as die gehipostaseerde spieelbeeld van die konkrete outeur in sy werk. So sal daar dan onderskei kan word tussen die abstrakte outeur as wesenspersoonlikheid soos hy werksaam is in/abstraheerbaar is uit, \u27n feitelike teks soos bv. \u27n outobiografie, en die abstrakte outeur as "digter"-persoonlikheid wat \u27n verbeeldingsteks (roman) daarstel. In sy gepubliseerde vorm bestaan die roman of boek-as-teks uit sowel die verhaalteks (produk van die "digter") as die skrywersteks wat toeligtend - bv. by wyse van motto, sub- of hoofstuktitels - daarby verskyn en wat op rekening van die self (wesenspersoonlikheid) geplaas moet word. Op die wyse word die abstrakte outeur as dubbele entiteit in die skrywersteks verteenwoordig en dien lg. as skakel tussen daargestelde wereld en empiriese wereld

The Abstract Author
The Bachelor's thesis focuses on the concept of so called abstract author. It deals with various forms of abstract author's subject developed in literary theory and narratology: scriptor of R. Barthes, implied author of W. Booth, model author of U. Eco or abstract author of W. Schmid. Futher, the differences between the concepts and the polemics that accompany them (Chatman, Rimmon-Kenanová etc.) are reflected

In C. ozbeki and C. vespiformis T1 is black or red (Figs 1–2) (with a very small spot on some C. vespiformis males), and the mesosoma and abdomen are all yellow with some pale red in C. pagliano female. The male of C. pagliano is undescribed. Also, the setae of the head and propodeum are shorter and more sparse in C. wahisi sp. nov. (Fig. 6), compared to C. vespiformis. The foremetatarsus of the female has five spines in C. vespiformis, and four spines in the other species, including C. wahisi sp. nov. (Fig. 7). The ocelli of C. wahisi sp. nov. are smaller than in the remaining species (Fig. 6), and the propodeal surface is more finely sculptured than in C. vespiformis. The male of C. wahisi sp. nov. is also characterized by having a higher and more rounded keel of S8 (seen in lateral view, Fig. 8), compared to C. vespiformis (Fig. 9). T1 is predominantly yellow, and all black or at most with a small medial yellow spot in C.vespiformis. Description of female holotype. Body length 20.0 mm. Colour.
