Book Review: the adaptation industry: the cultural economy of contemporary literary adaptation

Adaptation constitutes the driving force of contemporary culture, with stories adapted across an array of media formats. Until now, adaptation studies has been concerned almost exclusively with textual analysis, in particular with compare-and-contrast studies of individual novel and film pairings. The Adaptation Industry re-imagines adaptation not as an abstract process, but as a material industry. It presents the adaptation industry as a cultural economy of interlocking institutions, stakeholders and decision-makers all engaged in the actual business of adapting texts. Casey Brienza finds that the book is a fantastic contribution to the social scientific literature on cultural production and highly recommends it to all scholars in that fiel

On the population of remnant FRII radio galaxies and implications for radio source dynamics

The purpose of this work is two-fold: (1) to quantify the occurrence of ultra-steep spectrum remnant FRII radio galaxies in a 74 MHz flux limited sample, and (2) perform Monte-Carlo simulations of the population of active and remnant FRII radio galaxies to confront models of remnant lobe evolution, and provide guidance for further investigation of remnant radio galaxies. We find that fewer than 2$\%$ of FRII radio galaxies with S$_{ \rm74~MHz} > 1.5$ Jy are candidate ultra-steep spectrum remnants, where we define ultra-steep spectrum as $\alpha_{\rm 74~MHz}^{\rm 1400~MHz} > 1.2$. Our Monte-Carlo simulations demonstrate that models involving Sedov-like expansion in the remnant phase, resulting in rapid adiabatic energy losses, are consistent with this upper limit, and predict the existence of nearly twice as many remnants with normal (not ultra-steep) spectra in the observed frequency range as there are ultra-steep spectrum remnants. This model also predicts an ultra-steep remnant fraction approaching 10$\%$ at redshifts $z < 0.5$. Importantly, this model implies the lobes remain over-pressured with respect to the ambient medium well after their active lifetime, in contrast with existing observational evidence that many FRII radio galaxy lobes reach pressure equilibrium with the external medium whilst still in the active phase. The predicted age distribution of remnants is a steeply decreasing function of age. In other words young remnants are expected to be much more common than old remnants in flux limited samples. For this reason, incorporating higher frequency data $\gtrsim 5$ GHz will be of great benefit to future studies of the remnant population.Comment: 19 pages, 8 figures, 4 table

Book review: internet literature in China by Michel Hockx

This book examines the budding Chinese literary communities and their practices on the Internet. In Internet Literature in China, author Michael Hockx’s theoretical use of postsocialism as an organizing concept in the exploration of China’s online literary communities is what makes this such a fantastic contribution, writes Casey Brienza

The life cycle of radio galaxies as seen by LOFAR

Dit proefschrift onderzoekt de verschillende evolutionaire fases die waargenomen worden in radiosterrenstelsels. Wat deze sterrenstelsels bijzonder maakt is de aanwezigheid van een superzwaar zwart gat in hun centrum, dat het omringende materiaal aantrekt onder invloed van zijn enorme zwaartekracht. Gedurende dit proces worden twee bundels van relativistische deeltjes gevormd (ook wel: jets), die tot buiten het oorspronkelijke sterrenstelsel uitdijt en het merendeel van hun energie uitzenden op radiofrequenties. Deze jets komen periodiek voor en kunnen een substantiële invloed hebben op het sterrenstelsel. Het is dan ook van cruciaal belang om hun evolutie en de tijdschaal van hun activiteit te bestuderen om het totale proces van de formatie van sterrenstelsels te begrijpen. In het bijzonder hebben we in dit proefschrift de eigenschappen en evolutie van restanten en herstarte radiosterrenstelsels bestudeerd, wat respectievelijk overeenkomt met de fases waarin de jets stoppen of herstarten. Voor dit project hebben we op uitgebreide schaal gebruik gemaakt van de LOw Frequency ARray (LOFAR), een nieuwe generatie radiotelescoop gestationeerd in Nederland, waarmee de hemel wordt waargenomen op frequenties lager dan 250 MHz. Waarnemingen op MHz-frequenties zijn ideaal voor het bestuderen van de oudste emissie die geproduceerd is door de jets van herstarte of restanten van radiosterrenstelsels gedurende eerdere fases van activiteit. Daarmee stellen ze ons in staat om de evolutie van radiosterrenstelsels over een lange tijdschaal te reconstrueren

Paying twice or paying thrice? Open access publishing in a global system of scholarly knowledge production and consumption

UK open access policy does not exist in a vacuum. Casey Brienza argues that UK researchers represent too small a proportion of global scholarly knowledge production and consumption to rebalance scholarly expenditure. UK open access initiatives as currently formulated will instead lead to a significant de facto increase in costs for the UK. Instead of paying twice, once to fund the research and again to pay subscription fees to access that research, the public will find itself, in effect, paying thrice—once to fund the research, once to fund open access global publication and dissemination of the results of the research, and a third and final time to pay subscription fees to access critical research conducted throughout the rest of the world

Book review: ethnography for the internet: embedded, embodied and everyday

Ethnographers of contemporary Internet-infused societies consequently find themselves facing serious methodological dilemmas: where should they go, what should they do there and how can they acquire robust knowledge about what people do in, through and with the internet? Casey Brienza thinks Ethnography for the Internet is both a challenging and magisterial book by a scholar working at the fullest extent of her powers

Enriquecimento de florestas secundárias como tecnologia de produção sustentáveis para a agricultura familiar.

A capacidade produtiva da agricultura tradicional de corte e queima pode ser melhorada por meio do plantio de árvores de crescimento rápido durante o período de pousio, com o objetivo de acumular biomassa e nutrientes para uso na fase agrícola subsequente. Para isso, são desejados alguns atributos das espécies florestais a serem usadas no enriquecimento da capoeira. O plantio das espécies florestais leguminosas Acacia mangium (acácia), Inga edulis (ingá), Acacia angustissima (ligeirinha) e Sclerolobium paniculatum (taxi-branco), a partir da fase agrícola (milho e mandioca), no espaçamento 2 m x 2 m, apresentou bons resultados para a porcentagem de sobrevivência, acúmulo de biomassa e volume de madeira. O acúmulo de biomassa seca proporcionado pelas árvores plantadas variou de 35-40 t ha-1 (acácia) a 10-15 t ha-1 (taxi-branco). A análise do impacto do enriquecimento na redução do tempo de pousio mostrou que o sistema de enriquecimento formado com A. mangium proporcionou, em três anos (um ano de cultivo agrícola + dois anos de pousio enriquecido), um acúmulo de biomassa equivalente a cinco anos de pousio tradicional
