Looking for the Holy Grail: Publishing and advertising strategies and contemporary men's magazines

Recent work in gender/queer theory has developed J. L. Austin's notion of performativity to account for the compulsive and repetitive construction of gender as a kind of ‘performance’. This work has failed to examine the role of ‘sound’ in Austin's theory, with important consequences for our understanding of the basis of such an ‘ordinary’ communicative event. This article compares the problems which Austin raises for the securing of communicative events through a concept of sound with the sound experiment in the 1970s pornographic film, The Opening of Misty Beethoven. By linking this complex filmic disruption of the interrelation between desire, sexual performance and sound with a non-Derridean exploration of Austin, this study suggests that theories of the communicative event can be much enriched by examining ideas underlying ‘ordinary sexual intercourse’.     

Relighting the Campfire: Rediscovering Activity-Based Group Work

Group Work Camp, sponsored by Association for the Advancement of Social Work with Groups (AASWG) and held during the summers of 2009 and 2011 on the campus of George Williams College of Aurora University, provided unique opportunities for educators, practitioners, and students to experience the power of collective action and activity/experience-based groups. The camp reminded participants of the origins of the group work movement and how the prevalence of experientially based group practice has diminished over the past few decades. Further, this camp experience served as an awakening and may have particular import for U.S.-based practitioners to align with emerging trends in global social group work.     

Autonomous Youth? Independence and Precariousness in the Indonesian Underground Music Scene

Indonesia boasts a thriving underground music scene that has become an important element in the identity practices of many urban youth. For dedicated ‘scenesters’, the underground is more than a personal expression of style; it is a way of life, and often a way to make a living. I draw on the concept of ‘precarity’ to examine the underground value of independence (kemandirian) in the context of the precarious position of urban youth in neoliberal Indonesia. The identities and practices of the underground scene are both a reaction against and a reflection of this experience. Scenesters draw on their underground identities, and the autonomous community networks they have established, in order to assert their independence from the demands of capital. However, they also mobilise this independence as the basis for their own entrepreneurial activities, resulting in a nascent tendency towards capital accumulation and class polarisation within the scene.     

Self-generated motives for gambling in two population-based samples of gamblers

In the present study, self-generated responses to a question regarding reasons for gambling from two epidemiological surveys were combined and placed into another earlier motivational model for alcohol use, adapted for gambling. Of the 3601 reasons, 954 could be categorised into the model's categories: (a) coping motives (internal, negative reinforcement); (b) enhancement motives (internal, positive reinforcement); and (c) social motives (external, positive reinforcement). Results indicate that coping gamblers experienced greater gambling severity and psychopathology, enhancement gamblers were most likely to gamble while intoxicated and social gamblers were more likely to choose socially-related gambling. An examination of remaining motives suggests additional categories may be warranted – specifically financial and charitable reasons. These findings offer some support for the model; however, it may need to be expanded to account for other motives. The study highlights the advantages and limitations of using self-generated reasons to study gambling motivation.     

Replenishment Strategies for Micro‐Retailers in Developing Countries

When formal distribution channels are absent in developing countries, micro‐retailers travel a long distance to replenish their stocks directly from suppliers. This “informal” replenishment strategy is inefficient due to high imputed travel costs involved in the replenishment process. To improve efficiency, one “hybrid” replenishment strategy has emerged under which one of the micro‐retailers in a neighborhood, while continuing its own retail business, also operates as a wholesaler to serve other micro‐retailers in the neighborhood. A major obstacle for the transition from the informal strategy to the hybrid strategy is that the micro‐retailers are reluctant to source from a wholesaler who also competes with them in the retail market. Thus, it is not clear when the micro‐retailers adopt the hybrid strategy instead of the informal strategy. Meanwhile, the micro‐retailers may prefer the “formal” strategy: a traditional replenishment strategy under which one of the micro‐retailers relinquishes its retail business and operates purely as a wholesaler. We examine a situation when competing micro‐retailers contemplate with the three potential aforementioned replenishment strategies. Our equilibrium analysis of the two‐store model reveals that the dominant strategy is: (a) the hybrid strategy when the travel cost is high; (b) the formal strategy when the travel cost is medium; and (c) the informal strategy when the travel cost is low. This key insight is shown continue to hold when we extend the two‐store model to incorporate other issues including: quantity discounts from the supplier, variable operating costs, price competition, local monopolies, and different decision sequences. One additional finding is that the transition from the informal strategy to the hybrid strategy could benefit consumers if the micro‐retailers receive quantity discounts from the supplier. Furthermore, when there are more than two stores, we show that the formal strategy is never dominant. Moreover, when the number of stores increases, the hybrid strategy becomes more preferable to the informal strategy.     

Improving robustness of next-hop routing

A weakness of next-hop routing is that following a link or router failure there may be no routes between some source-destination pairs, or packets may get stuck in a routing loop as the protocol operates to establish new routes. In this article, we address these weaknesses by describing mechanisms to choose alternate next hops. Our first contribution is to model the scenario as the following tree augmentation problem. Consider a mixed graph where some edges are directed and some undirected. The directed edges form a spanning tree pointing towards the common destination node. Each directed edge represents the unique next hop in the routing protocol. Our goal is to direct the undirected edges so that the resulting graph remains acyclic and the number of nodes with outdegree two or more is maximized. These nodes represent those with alternative next hops in their routing paths. We show that tree augmentation is NP-hard in general and present a simple \(\frac{1}{2}\)-approximation algorithm. We also study 3 special cases. We give exact polynomial-time algorithms for when the input spanning tree consists of exactly 2 directed paths or when the input graph has bounded treewidth. For planar graphs, we present a polynomial-time approximation scheme when the input tree is a breadth-first search tree. To the best of our knowledge, tree augmentation has not been previously studied.
