In this creative nonfiction essay, I traverse through permutations of “fractal mechanics” as a means of processing experiences of oppression and imagining revolutionary futures. I introduce fractal mechanics as a method for thinking through how “the institution,” broadly understood, travels and transmutes from physical structure localized in place to a set of internalized rule sets that bind themselves to transinstitutionalized “host bodies”—a NeoLiberation. Through a series of vignettes illustrating violent experiences of “inclusion,” I explore how the institution is reproduced in neoliberal constructions of inclusion, liberation, and justice. I then integrate critiques of liberation within neoliberal frames with crip imaginings of justice-in-relation to explicate how fractal mechanics can be understood not only as a method of oppression but also a method for revolution. I close with a series of imaginaries that encourage us to prefigure, or dream, a fractal politic of intercommunal connection.

Fabrics recovered from archaeological sites often are so badly degraded that fiber identification based on physical morphology is difficult. Although diagenetic changes may be viewed as destructive to factors necessary for the discernment of fiber information, changes occurring during any stage of a fiber's lifetime leave a record within the fiber's chemical and physical structure. These alterations may offer valuable clues to understanding the conditions of the fiber's growth, fiber preparation and fabric processing technology and conditions of burial or long term storage (1).Energy dispersive spectrometry has been reported to be suitable for determination of mordant treatment on historic fibers (2,3) and has been used to characterize metal wrapping of combination yarns (4,5). In this study, a technique is developed which provides fractured cross sections of fibers for x-ray analysis and elemental mapping. In addition, backscattered electron imaging (BSI) and energy dispersive x-ray microanalysis (EDS) are utilized to correlate elements to their distribution in fibers.

Typical Point

The author claims that an institution is any collectively accepted system of rules (procedures, practices) that enable us to create institutional facts. These rules typically have the form of X counts as Y in C, where an object, person, or state of affairs X is assigned a special status, the Y status, such that the new status enables the person or object to perform functions that it could not perform solely in virtue of its physical structure, but requires as a necessary condition the assignment of the status. The creation of an institutional fact is, thus, the collective assignment of a status function. The typical point of the creation of institutional facts by assigning status functions is to create deontic powers. So typically when we assign a status function Y to some object or person X we have created a situation in which we accept that a person S who stands in the appropriate relation to X is such that (S has power (S does A)). The whole analysis then gives us a systematic set of relationships between collective intentionality, the assignment of function, the assignment of status functions, constitutive rules, institutional facts, and deontic powers.

The construction of dams in rivers negatively affects ecosystems because dams violate the continuity of rivers, transform the biological and physical structure of the river channels, and the most importantly – alter the hydrological regime. The impact on the hydrology of the river can occur through reducing or increasing flows, altering seasonality of flows, changing the frequency, duration and timing of flow events, etc. In order to determine the extent of the mentioned changes, The Indicators of Hydrologic Alteration (IHA) software was used in this paper. The results showed that after the construction of Angiriai dam, such changes occurred in IHA Parameters group as: the water conditions of April month decreased by 31 %; 1-day, 3-days, 7-days and 30-days maximum flow decreased; the date of minimum flow occurred 21 days later; duration of high and low pulses and the frequency of low pulses decreased, but the frequency of high pulses increased, etc. The analysis of the Environmental Flow Components showed, that the essential differences were recorded in groups of the small and large floods, when, after the establishment of the Šušvė Reservoir, the large floods no longer took place and the probability of frequency of the small floods didn’t exceed 1 time per year.

Archaeological site mapping is important for both understanding the history as well as protecting them from excavation during the developmental activities. As archaeological sites generally spread over a large area, use of high spatial resolution remote sensing imagery is becoming increasingly applicable in the world. The main objective of this study was to map the land cover of the Itanos area of Crete and of its changes, with specific focus on the detection of the landscape’s archaeological features. Six satellite images were acquired from the Pleiades and WorldView-2 satellites over a period of 3 years. In addition, digital photography of two known archaeological sites was used for validation. An Object Based Image Analysis (OBIA) classification was subsequently developed using the five acquired satellite images. Two rule-sets were created, one using the standard four bands which both satellites have and another for the two WorldView-2 images their four extra bands included. Validation of the thematic maps produced from the classification scenarios confirmed a difference in accuracy amongst the five images. Comparing the results of a 4-band rule-set versus the 8-band showed a slight increase in classification accuracy using extra bands. The resultant classifications showed a good level of accuracy exceeding 70%. Yet, separating the archaeological sites from the open spaces with little or no vegetation proved challenging. This was mainly due to the high spectral similarity between rocks and the archaeological ruins. The satellite data spatial resolution allowed for the accuracy in defining larger archaeological sites, but still was a difficulty in distinguishing smaller areas of interest. The digital photography data provided a very good 3D representation for the archaeological sites, assisting as well in validating the satellite-derived classification maps. All in all, our study provided further evidence that use of high resolution imagery may allow for archaeological sites to be located, but only where they are of a suitable size archaeological features.

Careful Management

Malaysia is portrayed as one of the modern and developed Muslim nations. Its rapid modern development in physical structure impressed many people. However, little is known about the situation of its non-physical structure, particularly the religious and normative values. This paper rests on the stance that individuals’ religious values remain despite the nation’s effort towards modernisation, particularly in the relations of women and profession. To achieve the purpose, this article explores the paradoxes relating to the intricate relationships between the traditional feminine social expectations and modern engineering profession experienced by Muslim female engineers and students in Malaysia. The research is a structured interview design on thirty-six Muslim female engineers and engineering students. It found that there were potential self-presentation crises, particularly when women participated in a male-dominated workplace. The gendering issues in engineering overwhelmingly projected the collision between modernism and traditionalism. Such a blending situation depended on very careful management as being women with a clear expectation towards traditional feminine roles and responsibilities, while at the same time they have to present themselves in a business-like, modern manner in terms of competence, commitment and ambitious targets to claim a rightful place in the engineering world. Modernisation has not been able to change women’s traditional attitude. Though they may be modernised, educated and professional, these women are still traditional at heart.
