'Sense and respond' and 'autonomic' logistics: a review of US and UK developments

Until recently, platform-based, logistics applications required data to be physically downloaded and transferred between systems so that analysis could estimate the status of key components. In both the Sense and Respond Logistics (S&RL) and Autonomic Logistics (AL) systems, prognostics have been added to monitoring functions, effectively extending the reach of Combat Service Support (CSS). The scope the supply chain has also been expanded with the potential inclusion of some classes of supply within the AL approach. The real time and predictive aspects are relatively new logistics developments facilitated by the real-time communication of data while platforms are in operation. While the (Australian) Military Integrated Logistics Information System (MILIS) proposes to extend the reach of supply chain information to sub-unit level, it falls short of crossing the gap to link Health and Usage Monitoring System (HUMS), platform-based, data into the logistics continuum to provide end-to-end visibility, a foxhole-to-factory-to-foxhole perspective, of the supply chain. This paper will review developments in recent military applications of Autonomic Logistics and Sense & Respond Logistics in the United States Defense Forces and the military in the UK while also considering a selection of Australian Defence Force programs. It will state the case for application of Autonomic Logistics and Sense & Respond Logistics to the ASLAV and Bushmaster platforms, in a similar fashion to those employed in the US and the UK, as a source of accurate and up-to-date CSS information for the various levels of command

Twentieth century management theory in today's organization - how relevant is a forty-year-old model in the contemporary context of a call center

[Abstract]: In the search to find the solution to the ‘one best way’ to provide a conduit for contact between organizations and their customers, call centers represent a recent incarnation of the principles of scientific management developed in the first decades of the last century. This paper seeks to apply another iconic legacy of twentieth century management theory, Tuckman’s four-stage model of group development devised in 1965, to organizations which didn’t exist when the original idea was first postulated. How relevant are the ‘forming’, storming’, norming, and ‘performing’ stages of progression to an environment renowned for constant changes to group membership? In his 1977 revision of the four-stage model with Jensen, Tuckman acknowledged the limited capacity of the theory to account for transient participation in groups. This paper reports the findings of research which provides evidence that Tuckman’s model describes accurately the patterns of behaviour demonstrated by groups of newly selected call center workers completing their initial induction training in an Australian, semi-government, call center. Call centers provide a contemporary context for the application of Taylorist management principles, symbolic of practice more readily associated with the industrial revolution than with ‘modern’ organizations. Tuckman’s 1965 model has a similar resonance for call centers today

Taylorism, targets, technology and teams - compatible concepts? Evidence from a US call centre

Taylorism, targets and technology form a potent mix in call centres where groups of individuals are asked to perform as “teams”. In this paper we explore how ‘task’ oriented concepts interact with the ‘interpersonal relationship’ realm in an environment where group life dominates the notional foundation of a call centre’s organisational structure. Tuckman’s four stage model of sequential group development serves as the theoretical lens through which the role ‘teams’ play in the working environment of a large call centre is examined.Our analysis of structured interviews conducted in an outbound, financial services call centre in the southern United States reveals the mechanisms by which agents have interpreted their ‘team charter’ to focus on individual achievement of increased remuneration levels. The interplay between these variables indicate that reward mechanisms associated with simple Taylorist targets, imposed on the entry level call centre agents, mitigate against meaningful group development. The advancement through promotion based on individual performance to more challenging, less target based work, is in sharp contrast to their initial training period where ‘team building’ is an essential ingredient of skills acquisition

Progress toward synergistic hypermixing nozzles

Mean flow measurements were obtained for air-to-air mixing downstream of swept and unswept ramp wall mounted hypermixing nozzle configurations. Aside from the sweep of the ramps, the two nozzle configurations studied are identical. The nozzles inject three parallel supersonic jets at a 15 deg angle (relative to the wind tunnel wall) into a supersonic freestream. Mach number and volume fraction distributions in a transverse plane 11.1 nozzle heights downstream from the nozzle exit plane were measured. Data are presented for a freestream Mach number of three at a matched static pressure condition and also at underexpanded static pressure condition (pressure ratio = 5). Surface oil flow visualization was used to study the near wall flow behavior. The results indicate that the swept ramp injectors produce stronger and larger vortex pairs than the unswept ramp injectors. The increased interaction between the swept ramp model's larger vortex pairs yields better mixing characteristics for this model

A Pedagogy of Witnessing: Linguistic and Visual Frames of the Dark Side in the Multimodal Classroom

“A Pedagogy of Witnessing: Linguistic and Visual Frames of the Dark Side in the Multimodal Classroom,” focuses on the theoretical and practical benefits of implementing written, oral, and visual testimonies from traumatic history as a tool for teaching the importance of empathetic and ethical composition practices. Specifically, this dissertation provides resource material for a critical pedagogical model that supports “responsible witnessing” through short writing assignments and a final research project that analyze selected narratives, historical accounts, images, and films spanning World War II and the Vietnam War to more recent global events. My hope is that my work will be of interest to teachers of composition and communication and students who wish to bring approaches to understanding and responding to human and nonhuman suffering as well as social injustice into the classroom

Boundary layer analysis of a Centaur standard shroud

An analytical boundary layer investigation was carried out in conjunction with an experimental wind tunnel test to determine the discharge characteristics of the Centaur shroud ascent vent system on the Titan/Centaur launch vehicle. This involved estimating the effect of the local boundary layers on the vent discharge for vehicle Mach numbers ranging from 0.8 to 1.56. The growth of the boundary layer along the vehicle was influenced by the interaction with flanges protruding into the flow and by the longitudinal corrugations in the vehicle surface. The effects of the flange and corrugations were treated by approximate techniques. In addition, boundary layer calculations were made for a 3 percent model of the launch vehicle compared with experimental results

Proposal for the Expansion of the University of Richmond’s Campus Garden

In today’s society the growing, buying and consuming of local foods is skyrocketing in demand. It provides for a healthier and more sustainable lifestyle that the University has stated its interest in promoting. This project to expand the current community garden on campus would not only promote the University’s strives in sustainable practices, but also draw the community and campus together. This garden could produce foods that could be sold to the current dining services, and to the local community generating some profit from this community garden while also reducing the University’s spending on food for the dining hall. Furthermore, a graduate certificate program could be created at the University for those interested in some sort of agricultural practices at the school. This garden could be an outside lab for biology, ecology and other sciences while also giving the University the potential to create new classes in the science curriculum, for example an introduction to agriculture class. By expanding the current garden the University will reap the many benefits that it brings, while also appealing to the future generations that will be applying to the University in the years to come

Social Studies Literacy

The field of education is constantly evolving. It is the role of professionals in education to provide students with the best opportunity to be successful learners. One major element of modern American Education, literacy instruction in the content areas, has become a key point in the discussion of how to best educate students. For the better part of one hundred years, the notion that every teacher is a teacher of literacy has been considered best practice. Within the last thirty years, alternative methodologies for literacy instruction within the content areas have become more prevalent as the literacy scores of American students steadily decline. Thus, begging the question, is the “every teacher” model best practice, and do other literacy methodologies provide an opportunity for student content literacy growth? The purpose of this research study is to evaluate one such alternative research methodology, disciplinary literacy in a comparative study against the “every teacher” methodology to analyze which method provides larger growth for student’s Social Studies literacy in my local school district. Content area literacy is especially important in the field of social studies because of the skills the content teaches students and how those skills will assist students in their understanding of the modern world

Improving Opportunities for Students by Creating Pathways for Taking Art

According to research, art education has gone through a decline, causing a lack of opportunities for students to experience the development of creativity in the general classroom. These opportunities for students in the schools in this study become even harder at the secondary level. With these small schools, it falls on the leadership of the administration to solve the scheduling dilemma for all the students. A school improvement plan is put into place to help increase the pathways for taking art by extending the day at one of the schools and changing the schedules to better help both schools work together by sharing the same teacher to optimize the schedules by making changes to fit the majority of the students from both schools

Development of seeding techniques for small supersonic wind tunnel

The NASA Lewis 1x1 foot supersonic wind tunnel is used to experimentally verify computational methods. This tunnel, which is continuous running, operates from laboratory-wide high pressure air and vacuum systems. As such, the air does not recirculate but makes a single pass through the tunnel. The Mach number is varied with interchangeable nozzle blocks and has a range from Mach 1.6 to 4.0. Dry and filtered air is available up to pressures of 3 atmospheres. The air enters the tunnel system through a plenum having flow straighteners and 6 fine mesh screens. The exit of the plenum provides smooth contraction with an area ratio of approximately 20 that, along with the screens, provides a uniform flow for the nozzle
