Burning Man Values Examined: Gratitude as a Culturally-Driven and Value-Based Organizational Mainstay

Gratitude expression is examined as a culturally-derived principle that can be adopted as a best practices strategy that can make organizations more dynamic and human relationships more meaningful. Burning Man is presented as an exemplar of gratitude implementation by crafting the expression of gratitude into an elevated organizational phenomenon (including a cultural principal of unconditional gifting). Burning Man has also crafted a “Culture of Appreciation” as a set of organizationally-derived practices complementary to processes of gratitude implementation. The paper concludes with a discussion of gratitude and appreciation as an organizational mainstay

The UV absorption spectrum of C60 (buckminsterfullerene): A narrow band at 3860 Å

The absorption spectrum of the special C60 cluster buckminsterfullerene has been studied in a supersonic beam by laser depletion of the cold van der Waals complexes of C60 with benzene and methylene chloride. Both complexes were found to display a single, isolated absorption band in the near ultraviolet superimposed on a structureless absorption continuum. For the methylene chloride complex this feature is centered at 3860 Å, and is roughly 50 cm−1 wide. In the benzene van der Waals cluster, the corresponding feature is located at 3863 Å, and has a similar width. This spectrum is tentatively assigned to the 0–0 band of the lowest 1T1u<--1Ag (LUMO+1<--HOMO) transition of a truncated icosahedral carbon shell structure, broadened by coupling to the underlying quasicontinuum of ground state vibrational levels

Theta Wave Coherence in Pre-Semantic Processing: An EEG study of Autism Spectrum Disorder

Language deficits are a pertinent and characteristic feature of Autism Spectrum Disorder (ASD), particularly in higher-level functions like semantic processing. Compared to the typically developing (TD) population, people with ASD have shown significant differences in neural semantic processing activity after the presentation of a stimulus. However, lower-level functions like word decoding are typically intact, suggesting a disconnect between these two processing levels in the brain. Theta coherence has been linked to the presence of such lower-level, pre-semantic activity in the TD population. The present study used electroencephalography (EEG) to measure the presence of theta coherence and examine the pre-semantic neural connectivity of participants with ASD to determine whether early disruptions might contribute to semantic misunderstandings. Gaining a better understanding of neural communication during pre-semantic processing would further the current understanding of language impairments in ASD and could also lead to more targeted and effective therapies

The Electronic Spectrum of Fullerenes from the Dirac Equation

The electronic spectrum of sheets of graphite (plane honeycomb lattice) folded into regular polihedra is studied. A continuum limit valid for sufficiently large molecules and based on a tight binding approximation is derived. It is found that a Dirac equation describes the flat graphite lattice. Curving the lattice by insertion of odd numbered rings can be mimicked by coupling effective gauge fields. In particular the $C_{60}$ and related molecules are well described by the Dirac equation on the surface of a sphere coupled to a color monopole sitting at its center.Comment: 29 pages, 7 figures.

Reality check: Asynchronous instruction works!

Never before had I asked a student to cite an emoticon. In traditional classroom instruction, it is unlikely that this would have come up at all. However, in an asynchronous course, you never know where an online threaded discussion on citation formats will lead. As library educators, we have the opportunity to have an impact on a student\u27s chances for success in locating and managing information. We must draw upon the students\u27 familiarity with new technologies and teach them how to effectively articulate their information need, identify appropriate resources, evaluate what has been retrieved, and redirect their continued searching. The challenge that confronts us is compounded by the fact that many students enter the library only through a virtual door. In recognition of the shifting paradigm involving information and new technologies, Purdue University\u27s Electrical Engineering Technology (EET) program asked the Purdue Libraries to develop a credit course that would teach the students how to effectively locate, evaluate, and present information. The course, Information Strategies, has been a required course in EET was designed and taught by the libraries\u27 faculty since 1993. It has subsequently been adapted to other disciplines, as well. As evolution of new technologies continued, course instructors proposed the development of an asynchronous version of this course to the Indiana Higher Education Telecommunications System (IHETS). The development grant was awarded and the first Web-based version of this course was offered Spring 1999. The purpose of the IHETS course development grant was to enhance and convert [the Information Strategies course] to a digital format, which will allow asynchronous statewide access. In July 1998, the investigators, Professors Sheila Curl, Leslie Reynolds, Brent Mai, and Alexius Smith, began adapting the traditional course for delivery over the Internet

Photophysics of buckminsterfullerene and other carbon cluster ions

The laser-induced fragmentation behavior of positive carbon cluster ions has been investigated by tandem time-of-flight techniques for the jet-cooled clusters up to 80 atoms in size. Two distinct photophysical regimes were found. The first applies to clusters with 34 atoms or more, all of which dissociate to produce even numbered fragments. Large even clusters fragment by the loss of the high energy species C2, odd ones lose a C atom. The second regime applies to clusters composed of 31 or less atoms, all of which fragment by the loss of C3. These two regimes are sharply separated by C + 32 which fragments to produce small cluster ions in the 10–19 atom size range. Fragmentation of the large clusters occurs on a microsecond or faster time scale only at very high levels of excitation (>12.8 eV). These photophysical results are interpreted as consequences of the large even clusters having edgeless, spheroidal cage structures while the small ones have linear chain or ring structures

Soil organisms in organic and conventional cropping systems.

Apesar do crescente interesse pela agricultura orgânica, são poucas as informações de pesquisa disponíveis sobre o assunto. Assim, num Argissolo Vermelho-Amarelo distrófico foram comparados os efeitos de sistemas de cultivo orgânico e convencional, para as culturas do tomate (Lycopersicum esculentum) e do milho (Zea mays), sobre a comunidade de organismos do solo e suas atividades. As populações de fungos,bactérias e actinomicetos, determinadas pela contagem de colônias em meio de cultura, foram semelhantes para os dois sistemas de produção. A atividade microbiana, avaliada pela evolução de CO2, manteve-se superior no sistema orgânico, sendo que em determinadas avaliações foi o dobro da evolução verificada no sistema convencional. O número de espécimes de minhoca foi praticamente dez vezes maior no sistema orgânico. Não foi observada diferença na taxa de decomposição de matéria orgânica entre os dois sistemas. De modo geral, o número de indivíduos de microartrópodos foi superior no sistema orgânico do que no sistema convencional, refletindo no maior índice de diversidade de Shannon. As maiores populações de insetos foram as da ordem Collembola, enquanto para os ácaros a maior população foi a da superfamília Oribatuloidea. Indivíduos dos grupos Aranae, Chilopoda, Dyplopoda, Pauropoda, Protura e Symphyla foram ocasionalmente coletados e de forma similar entre os sistemas
