The Cultural Construction of the Maine Sporting Camps

Maine sporting camps were a cultural and social phenomenon of the urban upper and middle class. They originated in Maine in the late 1870s and early 1880s and reached their zenith around the turn of the century with over 160 in operation in eight of the sixteen counties in Maine in 1906. The period from 1880 until World War I can be considered the 'golden era' of the Maine sporting camps. After the war, with technological advancements such as the outboard motor, the proliferation of the automobile, and the introduction of a road system into rural Maine, the camps underwent significant change that warrants an entirely different cultural analysis. A number of elements came together to produce a cultural atmosphere permissive of sporting camp creation in Maine. These include changing national views upon nature, health, sport and the leisure time in which to pursue them. In the late nineteenth century, with the rise of large industrially based cities, overcrowding fostered crime and disease. An upper and middle class emerged that desired escape and separation from the lower classes. Maine was chosen for such an escape because it offered, through sporting camps, a chance to "get back to nature," by pursuing the healthful activities of hunting and fishing. At the same time these urban sportsmen and sportswomen distinguished themselves on the social Hierarchical scale from the rural inhabitants. What happened in rural Maine during the period between 1880 and World War I was the introduction of a new cultural order on the landscape. Coming primarily from urban centers on the East Coast of the United States were men, women and children who looked to Maine for vacations. These vacations were designed to put them in touch with nature by pursuing healthful activities, especially those of fishing and hunting. Coming from an environment that emphasized social standing, they ensured that these trips would perpetuate this hierarchy. They experienced nature through the Maine sporting camps, which provided them with the services and skills necessary to experience it while enjoying a degree of luxury that they were accustomed to in the urban world. The Maine sporting camps were a cultural manifestation of the urban upper and middle class, the groups that the camps were established to serve. Despite this the camps did not represent a structural duplication of urban society. Instead, the camps represented a cultural construction that was produced by interaction between members of two different conceptual and physical worlds, the blending of which, on a social level, was determined by urban mentality and rural knowledge. In the production of a cultural world meaningful to the clients, the rural world of the Maine woods was altered to meet their needs. It was not a one-sided process, however, as the clients were forced to acknowledge the importance of the rural inhabitants on the basis of their value to the clients.

On the coupling of the self-dual field to dynamical U(1) matter and its dual theory

We consider arbitrary U (1) charged matter non-minimally coupled to the self-dual field in d = 2 + 1. The coupling includes a linear and a rather general quadratic term in the self-dual field. By using both Lagragian gauge embedding and master action approaches we derive the dual Maxwell Chern-Simons-type model and show the classical equivalence between the two theories. At the quantum level the master action approach in general requires the addition of an awkward extra term to the Maxwell Chern-Simons-type theory. Only in the case of a linear coupling in the self-dual field can the extra term be dropped and we are able to establish the quantum equivalence of gauge invariant correlation functions in both theories.

The efficacy of the self-adjusting file and ProTaper for removal of calcium hydroxide from root canals

Objective: The goal of this study was to evaluate the efficacy of the Self-Adjusting File (SAF) and ProTaper for removing calcium hydroxide [Ca(OH)2] from root canals. Material And Methods: Thirty-six human mandibular incisors were instrumented with the ProTaper system up to instrument F2 and filled with a Ca(OH)2-based dressing. After 7 days, specimens were distributed in two groups (n=15) according to the method of Ca(OH)2 removal. Group I (SAF) was irrigated with 5 mL of NaOCl and SAF was used for 30 seconds under constant irrigation with 5 mL of NaOCl using the Vatea irrigation device, followed by irrigation with 3 mL of EDTA and 5 mL of NaOCl. Group II (ProTaper) was irrigated with 5 mL of NaOCl, the F2 instrument was used for 30 seconds, followed by irrigation with 5 mL of NaOCl, 3 mL of EDTA, and 5 mL of NaOCl. In 3 teeth Ca(OH)2 was not removed (positive control) and in 3 teeth canals were not filled with Ca(OH)2 (negative control). Teeth were sectioned and prepared for the scanning electron microscopy. The amounts of residual Ca(OH)2 were evaluated in the middle and apical thirds using a 5-score system. Results: None of the techniques completely removed the Ca(OH)2 dressing. No difference was observed between SAF and ProTaper in removing Ca(OH)2 in the middle (P=0.11) and the apical (P=0.23) thirds. Conclusion: The SAF system showed similar efficacy to rotary instrument for removal of Ca(OH)2 from mandibular incisor root canals.

A new number field construction of the lattice E8

Ethical Care of the Self and the Teacher in the Pedagogical Relationship: Reflections Based on the Latest Foucault

Our conception of education is that it is the responsible action whereby man becomes human, trains and faces the challenges that life and the world present, as man enters a larger, shared cultural tradition and thus joins the world. However such sharing implies that we must not just rely on tradition, but remain open to new ideas. It is essential for schooling to preserve a field where the art of living intersects with the world for which future generations are being prepared. It is in this field of intersection that this essay seeks to discuss Michel Foucault's thought, care of the self and the role played by others in the acquisition of ethical attitudes pertaining to one's conduct in life. Through reconstructing Foucault's ideas, we elaborate on the hypothesis that, before morally shaping students, teaching them values, or aiding in their skill acquisition in the sense prevailing in schooling today, it is important to understand the notion of care of the self (and how the notion implies interaction with others for effective care of the self). Care of the self is vital for thoroughly understanding the relationships between ethics and education in school. We particularly examine how Foucault's ideas and his analysis of the teacher's role in shaping the student's life conduct can help educators rethink pedagogical action in an ethical sense and find within it a certain openness to the formation of attitudes in educators and students

Construction of the dispositions of institutional habitus in the academic field

This paper describes the main phases of development of an Institute of Chemistry in relation with national policy from the academic field. Its history begins with a proposal to meet the demand for chemistry teacher education and goes on to become a major center for research, education and extension. Throughout its 50 years of history, the Institution has faced numerous challenges by adopting strategies that have established and revealed its institutional habitus. To this end, we use some of René Kaës’s concepts about the development of groups and institutions, highlighting mainly the origins, expectations and covenants that underpinned its foundation, and the entire process of its expansion and institutionalization. Our main focus, also interpreted based on the theory of Pierre Bourdieu and followers, is the establishment of its institutional habitus, i.e., how it interprets and organizes its institutional teaching, research and extension activities within the context of the academic field. The peculiarity of the process has been the mismatch between internal and external pressures. Even though presenting the results of a case study, in general, our methodology can improve the understanding of institution’s development in relation with educational policy.

The construction of the African perspective: a history of the General History of Africa project (Unesco)

This article analyzes the construction of the African perspective in the General History of Africa project (GHA), focusing on the period between 1965 and 1979. With the participation of over two hundred international experts under the auspices of Unesco, this was one of the greatest intellectual projects of the twentieth century. Based on primary sources, this analysis emphasizes the internal conflicts involved in the construction of the African perspective as a hegemonic line of thought in the GHA. Two critical moments of the project were found in the investigation: the controversial years (1972-78), and the pragmatic years (1978-82). As a result of these disputes, theoretical and methodological parameters were constructed, in addition to eight volumes of material published in the 1980s, and recently republished in Brazil.

Structural, Spectroscopic (NMR, IR, and Raman), and DFT Investigation of the Self-Assembled Nanostructure of Pravastatin-LDH (Layered Double Hydroxides) Systems

Layered double hydroxide (LDH) nanocontainers, suitable as carriers for anionic drugs, were intercalated with Pravastatin drug using magnesium-aluminum and zinc-aluminum in a M-II/Al molar ratio equal 2 and different Al3+/Pravastatin molar ratios. Postsynthesis treatments were used in order to increase the materials crystallinity. Hybrid materials were characterized by a set of physical chemical techniques: chemical elemental analysis, X-ray diffraction (XRD), mass coupled thermal analyses, vibrational infrared and Raman spectroscopies, and solid-state C-13 nuclear magnetic resonance (NMR). Results were interpreted in light of computational density functional theory (DFT) calculations performed for Sodium Pravastatin in order to assign the data obtained for the LDH intercalated materials. XRD peaks of LDH-Pravastatin material and the one-dimensional (1D) electron density map pointed out to a bilayer arrangement of Pravastatin in the interlayer region, where its associated carboxylate and vicinal hydroxyl groups are close to the positive LDH. The structural organization observed for the stacked assembly containing the unsymmetrical and bulky monoanion Pravastatin and LDH seems to be promoted by a self-assembling process, in which local interactions are maximized and chloride ion cointercalation is required. It is observed a high similarity among vibrational and C-13 NMR spectra of Na-Pravastatin and LDH-Pravastatin materials. Those features indicate that the intercalation preserves the drug structural integrity. Spectroscopic techniques corroborate the nature of the guest species and their arrangement between the inorganic layers. Changes related to carboxylate, alcohol, and olefinic moieties are observed in both vibrational Raman and C-13 NMR spectra after the drug intercalation. Thus, Pravastatin ions are forced to be arranged as head to tail through intermolecular hydrogen bonding between adjacent organic species. The thermal decomposition profile of the hybrid samples is distinct of that one observed for Na-Pravastatin salt, however, with no visible increase in the thermal behavior when the organic anion is sequestrated within LDH gap.
