Children in post-Revolutionary Iranian cinema : visions of the future

textThis project focuses on children in Iranian cinema in the Islamic Republic era in order to examine how child characters reveal visions of their future in Iran. This analysis will help the reader understand how privilege functions in relation to citizenship in Iran. Prior research argues that children in Iranian cinema represent humanist themes and utopic images of Iranian society. My thesis builds on this work to argue that images of the child represent more nuanced imaginings of the future, dependent on their ability to confront problems successfully. This study does not consider children's films, but rather films with prominent child characters. It looks at child characters both as agents whose desires and anxieties drive the film's action and as objects with whom the audience can visualize the future. This project includes Children of Heaven (Bachcheh-hā-ye āsemān), The Mirror (Āineh), Where is the Friend's Home (Khāne-ye dust kojāst), Bashu, the Little Stranger (Bāshu gharibe-ye kuchek), Baran (Bārān), The Apple (Sib), Life, and Nothing More (Zandegi va digar hich), The White Balloon (Bādkonak-e sefid), and The Day I Became a Woman (Ruzi ke zan shodam). My thesis argues that the ways in which child characters interact with their environment highlight their level of privilege, revealing what types of individuals are best fit to thrive in Iranian society under the Islamic Republic. I argue that notions of citizenship and nationalism are integral to the characters' identities and indicated futures. Specifically, both ideal children and non-ideal children who maintain Iranian citizenship will have successful futures as participants in Iranian society, while non-Iranian nationals may not.Middle Eastern Studie

Early Life Effects of a Dual Burden Environment: Childhood Intestinal Health and Immune Function in Galápagos, Ecuador

Early life pathogenic and nutritional environments impact health over the life course by training the immune system to adapt to local microbial conditions and developing metabolic trajectories based on resource availability. Exposure to environmental microbes during childhood, common throughout evolutionary history, can provide immunoregulatory properties that strengthen the immune system’s ability to resolve inflammation. In populations with childhood undernutrition, pathogenic exposures due to unsanitary living conditions can cause chronic intestinal inflammation. This condition, known as environmental enteric dysfunction, allows for microbes to enter the blood causing endotoxemia and systemic infection. Chronic immunostimulation during childhood is energetically demanding and often results in growth deficits. This dissertation uses the emerging field of the gut microbiome as pathway to investigate the early life effects of overnutrition and poor water quality on childhood intestinal health and immune function in Galápagos, Ecuador. Residents of San Cristóbal are unfortunately experiencing a dual burden of both increasing rates of obesity, coupled with persistent rates of infectious disease. Data was collected from 169 children aged two to ten and their 119 mothers. Interviews obtained information concerning household water use and sanitation practices, and children’s hygiene behaviors, illness histories and diets. Household water samples were collected to quantify fecal pathogens. Anthropometric assessments provided indicators of nutritional status. Blood spots were measured for immune biomarkers and fecal samples were collected to examine gut microbial compositions. Novel hypotheses are tested for the dual burden environment that examine the relationship between pathogenic and obesogenic factors on inflammation, endotoxemia and gut microbial composition, and provide insight into the early life health impacts of the dual burden environment on childhood intestinal health and immune function. The significant of this research is that even in the context of a pro-inflammatory state, driven by overweight and obesity, early life exposure to Escherichia coli contaminated water, which does not result in diarrhea, can provide an immunoregulatory effect among children in Galápagos. Identifying gut microbial symbiosis as a possible mechanism underlying this protective effect is an original contribution to the evolutionary “old friends” hypothesis and is of particular importance to public health research on environmental enteric dysfunction.Doctor of Philosoph

Abbas Kiarostami and Film-Philosophy, by Mathew Abbott

Mathew Abbott’s book, beautifully adorned with a now iconic still from The Wind Will Carry Us (Bād mā rā khāhad bord, 1999), explores the late Iranian filmmaker Abbas Kiarostami’s later films through the framework of film-as-philosophy. The book offers an analysis of cinema as a medium of serious philosophical production through a chronological case study of Kiarostami’s films, beginning in the introduction with Taste of Cherry (Ta’m-e gīlās, 1997)

Motion Cueing Algorithm Modification for Improved Turbulence Simulation

Atmospheric turbulence cueing produced by flight simulator motion systems has been less than satisfactory because the turbulence profiles have been attenuated by the motion cueing algorithms. Cardullo and Ellor initially addressed this problem by directly porting the turbulence model output to the motion system. Reid and Robinson addressed the problem by employing a parallel aircraft model, which is only stimulated by the turbulence inputs and adding a filter specially designed to pass the higher turbulence frequencies. There have been advances in motion cueing algorithm development at the Man-Machine Systems Laboratory, at SUNY Binghamton. In particular, the system used to generate turbulence cues has been studied. The Reid approach, implemented by Telban and Cardullo, was employed to augment the optimal motion cueing algorithm installed at the NASA LaRC Simulation Laboratory, driving the Visual Motion Simulator. In this implementation, the output of the primary flight channel was added to the output of the turbulence channel and then sent through a non-linear cueing filter. The cueing filter is an adaptive filter; therefore, it is not desirable for the output of the turbulence channel to be augmented by this type of filter. The likelihood of the signal becoming divergent was also an issue in this design. After testing on-site it became apparent that the architecture of the turbulence algorithm was generating unacceptable cues. As mentioned above, this cueing algorithm comprised a filter that was designed to operate at low bandwidth. Therefore, the turbulence was also filtered, augmenting the cues generated by the model. If any filtering is to be done to the turbulence, it will utilize a filter with a much higher bandwidth, above the frequencies produced by the aircraft response to turbulence. The authors have developed an implementation wherein only the signal from the primary flight channel passes through the nonlinear cueing filter. This paper discusses three new algorithms. Testing shows that the new methods provide the pilot with a more realistic sensation of turbulence; the cues are not attenuated by algorithm. Results of offline testing show the credibility of the models. Offline test verification was based primarily on the evaluation of the power spectral density of the outputs and the time response

Algorithm for Simulating Atmospheric Turbulence and Aeroelastic Effects on Simulator Motion Systems

Atmospheric turbulence produces high frequency accelerations in aircraft, typically greater than the response to pilot input. Motion system equipped flight simulators must present cues representative of the aircraft response to turbulence in order to maintain the integrity of the simulation. Currently, turbulence motion cueing produced by flight simulator motion systems has been less than satisfactory because the turbulence profiles have been attenuated by the motion cueing algorithms. This report presents a new turbulence motion cueing algorithm, referred to as the augmented turbulence channel. Like the previous turbulence algorithms, the output of the channel only augments the vertical degree of freedom of motion. This algorithm employs a parallel aircraft model and an optional high bandwidth cueing filter. Simulation of aeroelastic effects is also an area where frequency content must be preserved by the cueing algorithm. The current aeroelastic implementation uses a similar secondary channel that supplements the primary motion cue. Two studies were conducted using the NASA Langley Visual Motion Simulator and Cockpit Motion Facility to evaluate the effect of the turbulence channel and aeroelastic model on pilot control input. Results indicate that the pilot is better correlated with the aircraft response, when the augmented channel is in place

Motion Cueing Algorithm Development: Piloted Performance Testing of the Cueing Algorithms

The relative effectiveness in simulating aircraft maneuvers with both current and newly developed motion cueing algorithms was assessed with an eleven-subject piloted performance evaluation conducted on the NASA Langley Visual Motion Simulator (VMS). In addition to the current NASA adaptive algorithm, two new cueing algorithms were evaluated: the optimal algorithm and the nonlinear algorithm. The test maneuvers included a straight-in approach with a rotating wind vector, an offset approach with severe turbulence and an on/off lateral gust that occurs as the aircraft approaches the runway threshold, and a takeoff both with and without engine failure after liftoff. The maneuvers were executed with each cueing algorithm with added visual display delay conditions ranging from zero to 200 msec. Two methods, the quasi-objective NASA Task Load Index (TLX), and power spectral density analysis of pilot control, were used to assess pilot workload. Piloted performance parameters for the approach maneuvers, the vertical velocity upon touchdown and the runway touchdown position, were also analyzed but did not show any noticeable difference among the cueing algorithms. TLX analysis reveals, in most cases, less workload and variation among pilots with the nonlinear algorithm. Control input analysis shows pilot-induced oscillations on a straight-in approach were less prevalent compared to the optimal algorithm. The augmented turbulence cues increased workload on an offset approach that the pilots deemed more realistic compared to the NASA adaptive algorithm. The takeoff with engine failure showed the least roll activity for the nonlinear algorithm, with the least rudder pedal activity for the optimal algorithm

Subtle Cavus Deformities: Is Isolated Lateral Ankle Ligament Reconstruction Enough for Improved Patient-reported Outcomes?

Introduction/Purpose: Lateral ankle ligament injuries are common conditions accounting for 25% of musculoskeletal injuries. Prior reports have found increased risk of failed lateral ankle reconstruction in those with a subtle cavus deformity, and therefore, correcting the deformity is often advocated. However, other studies have been unable to identify subtle cavus deformity as a clear risk factor for recurrent injury. The purpose of this study was to 1) compare PROMIS physical function (PF), pain interference (PI), and depression scores in patients with subtle cavus deformities to those without deformity who underwent lateral ankle ligament reconstruction, 2) compare PROMIS scores in allograft and modified Brostrom-Gould (BG) reconstructions in those with subtle cavus, and 3) to evaluate for any post-operative complications in those with subtle cavus

Motion Cueing Algorithm Development: New Motion Cueing Program Implementation and Tuning

A computer program has been developed for the purpose of driving the NASA Langley Research Center Visual Motion Simulator (VMS). This program includes two new motion cueing algorithms, the optimal algorithm and the nonlinear algorithm. A general description of the program is given along with a description and flowcharts for each cueing algorithm, and also descriptions and flowcharts for subroutines used with the algorithms. Common block variable listings and a program listing are also provided. The new cueing algorithms have a nonlinear gain algorithm implemented that scales each aircraft degree-of-freedom input with a third-order polynomial. A description of the nonlinear gain algorithm is given along with past tuning experience and procedures for tuning the gain coefficient sets for each degree-of-freedom to produce the desired piloted performance. This algorithm tuning will be needed when the nonlinear motion cueing algorithm is implemented on a new motion system in the Cockpit Motion Facility (CMF) at the NASA Langley Research Center

A Transfer of Training Study of Control Loader Dynamics

The control inceptor used in a simulated vehicle is an important part in maintaining the fidelity of a simulation. The force feedback provided by the control inceptor gives the operator important cues to maintain adequate performance. The dynamics of a control inceptor are typically based on a second order spring mass damper system with damping, force gradient, breakout force, and natural frequency parameters. Changing these parameters can have a great effect on pilot or driver control of the vehicle. The neuromuscular system has a very important role in manipulating the control inceptor within a vehicle. Many studies by McRuer, Aponso, and Hess have dealt with modeling the neuromuscular system and quantifying the effects of a high fidelity control loader as compared to a low fidelity control loader. Humans are adaptive in nature and their control behavior changes based on different control loader dynamics. Humans will change their control behavior to maintain tracking bandwidth and minimize tracking error. This paper reports on a quasi-transfer of training experiment which was performed at the NASA Langley Research Center. The quasi transfer of training study used a high fidelity control loader and a low fidelity control loader. Subjects trained in both simulations and then were transferred to the high fidelity control loader simulation. The parameters for the high fidelity control loader were determined from the literature. The low fidelity control loader parameters were found through testing of a simple computer joystick. A disturbance compensatory task is employed. The compensatory task involves implementing a simple horizon out the window display. A disturbance consisting of a sum of sines is used. The task consists of the subject compensating for the disturbance on the roll angle of the aircraft. The vehicle dynamics are represented as 1/s and 1/s2. The subject will try to maintain level flight throughout the experiment. The subjects consist of non-pilots to remove any effects of pilot experience. First, this paper discusses the implementation of the disturbance compensation task. Second, the high and low fidelity parameters used within the experiment are presented. Finally, an explanation of results from the experiments is presented

Comparison of Flight Simulators Based on Human Motion Perception Metrics

In flight simulation, motion filters are used to transform aircraft motion into simulator motion. When looking for the best match between visual and inertial amplitude in a simulator, researchers have found that there is a range of inertial amplitudes, rather than a single inertial value, that is perceived by subjects as optimal. This zone, hereafter referred to as the optimal zone, seems to correlate to the perceptual coherence zones measured in flight simulators. However, no studies were found in which these two zones were compared. This study investigates the relation between the optimal and the coherence zone measurements within and between different simulators. Results show that for the sway axis, the optimal zone lies within the lower part of the coherence zone. In addition, it was found that, whereas the width of the coherence zone depends on the visual amplitude and frequency, the width of the optimal zone remains constant
