Congruences Among Power Series Coefficients of Modular Forms

Many authors have investigated the congruence relations amongst the coefficients of power series expansions of modular forms $f$ in modular functions $t$. In a recent paper, R. Osburn and B. Sahu examine several power series expansions and prove that the coefficients exhibit congruence relations similar to the congruences satisfied by the Ap\'ery numbers associated with the irrationality of $\zeta(3)$. We show that many of the examples of Osburn and Sahu are members of infinite families.Comment: 24 page

For Our Children: Childcare Concerns Link Postal Workers Across the Racial Divide in San Fransisco

[Excerpt] Celebrating diversity — it\u27s the latest trend for justice-minded union and community activists. Management, too, is interested in diversity: note the steady stream of articles, books, and seminars for business executives on the subject. Even President Clinton stated his desire to create an administration that looks like America. Listening to a union activist share her experiences of 20 years in the U.S. Postal Service is a good way to bring a dose of realism to the diversity hype. Karen Wing, a Chinese-American woman who is a shop steward and clerk in the San Francisco General Mail Facility, knows how very hard it is to build understanding and lasting unity among different nationalities. More than anything else, unions and activists trying to implement diversity programs need to emphasize patience and perseverance, Wing says. This is especially true on the shop floor, where workers may not have the full power of the international or local union structures behind them. The question Wing faced in her local was How do you organize in a diverse workplace when you are essentially \u27on your own?\u27 The problems are enormous. As a shop steward, people often come to Wing with their complaints. Some pro-union black workers ask, Why don\u27t those Asians speak English? Are they talking about me? Look how they play up to management, they don\u27t even care about the union. On the other hand, some Asian immigrant workers ask Wing, How can you work in the union? I can\u27t be a shop steward — my English isn\u27t good enough. And those black people are always complaining about work. Handling remarks like these is not easy. How do you fight a management that deliberately stirs up racial antagonisms? How do you build a union responsive to a diverse workforce? For Wing, meeting these challenges on the shop floor begins with knowing the history and changes occurring within the workplace

Efficient and Playful Tools to Teach Unix to New Students

Teaching Unix to new students is a common tasks in many higher schools. This paper presents an approach to such course where the students progress autonomously with the help of the teacher. The traditional textbook is complemented with a wiki, and the main thread of the course is a game, in the form of a treasure hunt. The course finishes with a lab exam, where students have to perform practical manipulations similar to the ones performed during the treasure hunt. The exam is graded fully automatically. This paper discusses the motivations and advantages of the approach, and gives an overall view of the tools we developed. The tools are available from the web, and open-source, hence re-usable outside the Ensimag.Comment: ITiCSE, Darmstadt : Germany (2011

VEIL Ballarat centre structural plan

This report looks at the future devlopment in Ballerat, Victoria. New forms of urban planning, housing and also transport and use of natural resouces are some of the major topics covered.  (1) BALLARAT - THE LOCALLY PRODUCTIVE CITY Goal: All precincts in Ballarat (exemplified by the CBA) aim to maximise production of environmentally and socially critical resources.Target: To be a net exporter in as many of the following areas as possible: Renewable energy - diverse systems - wind, solar, geothermal, biomass Water - rainwater, grey water, recycled Food production - close to points of consumption Community services Knowledge - research, innovation, education and skills. E.g: climate adaptation solutions; low-carbon solutions; sustainable agriculture (food and bio-mass) Green businesses, green services, eco-innovation (agricultural best practice and re-mining) "green zone" (2) BALLARAT - THE LOW CONSUMPTION CITYGoal: Living and Working Better - Consuming LessTarget: To develop the highest quality of living and working conditions with the lowest per-capita consumption and production of waste, in as many of the following areas as possible: Greenhouse gas (e.g. target: reductions of greater than 60%) Electricity use (e.g through retrofitting - 40% reduction) Water: (e.g. target 80 litres/person/day of reticulated potable water) Transport /mobility (e.g. target greater than 30% shift from car to walking & cycling; 25% reduction in car trip distances; 40% increase in public transport use) Waste reduction (e.g, in all sectors,40%) (3) BALLARAT - THE REGENERATIVE CITYGoal: Avoiding cascading breakdown effects, enabling quick bounceback from challenges - creating a social and physical fabric that is diverse, decentralised and locally inter-connected, so that any shocks (environmental or economic) will be limited in the spread of their effects.Target: To approach all planning and design decisions with the intent of increasing the diversity of communities, production systems (as in 1, above) and public facilities, particularly in relation to: access to energy, water, food, transport, the provision of work and residential facilities life in extreme weather conditions community engagement (4) BALLARAT - THE INVENTIVE CITYGoal: To achieve all of above through the development of innovative new solutions and approaches, building on the strong history of inventiveness and creativity in Ballarat (in agriculture and mining in particular).Target: Ballarat to be known nationally and internationally as supporting a culture of creative risk-taking, experimentation, and innovation in relation to climate resilience and sustainable solutions

The linewidth of a non-Markovian atom laser

We present a fully quantum mechanical treatment of a single mode atom laser including pumping and output coupling. By ignoring atom-atom interactions, we have solved this model without making the Born-Markov approximation. We find substantially less gain narrowing than is predicted under that approximation.Comment: 4 pages, 1 encapsulated postscript figur
