Indymedia.ie: a critical space for social movements in Ireland

“Hegemony” – the way popular consent to power and economic structures is organised – is an alien word to many people, seemingly coming from a different world to the familiar trivialities of Middle Ireland. But the complacent idea of Gay Byrne’s Late Late Show as the nation’s living room is a perfect example of hegemony at work: the state broadcaster offering a cosy, semi-official version of “national community”. Its liberal version appears in comments about how “it was a breakthrough” when something appeared on the Late Late: not grasping that “issues” make the mainstream media as a result, not a cause, of social movements struggling against the official state of affairs

Advancing Philanthropic Strategy Through Evaluative Thinking: One Foundation’s Approach

The Sisters of Charity Foundation of Cleveland supports Catholic sisters and their ministries in northeast Ohio through the grantmaking, partnership, capacitybuilding, and evaluation efforts of its Catholic Sisters Program Area. The decline of sisters actively engaged in ministry, due both to their rising median age and a decades-long decline in their overall numbers, called for a reconsideration and likely revision of the CSPA existing theory of change. Unlike other strategic approaches at the foundation, such as ending homelessness or improving health equity, transitioning from sister-led to lay-led leadership of ministries remained largely unexplored: Basic research was lacking, and model practices were simply not available. Therefore, CSPA staff engaged in a disciplined process to explore, measure, evaluate, and enhance its approach to supporting the legacy and current requirements of Catholic sisters within a rapidly changing environment. This article presents findings and lessons learned from a three-part evaluation process designed to offer an inclusive, systems-based approach to evaluation by identifying outcomes critical to CSPA success and salient areas of evaluative inquiry designed to strengthen the program area; develop a framework of key elements of gospel-inspired service as modeled by sisters, rooted in stakeholder and community input; and employ the conceptual framework to develop measurement tools for sisters and lay partners for ongoing data collection to strengthen existing efforts and plan for the future. Learnings from the systems-based evaluation process suggests and will inform a revision of CSPA’s theory of change, ensuring the foundation will continue to support and effectively promote the formation and activities of well-formed lay leaders and organizationally strong ministries to carry forward gospel-inspired service as modeled by sisters. This article concludes by discussing how this three-part evaluative approach contributes to an expanded understanding of how philanthropic strategic initiatives can be assessed and effectively adapted by foundations experiencing generational or leadership transition or other changing contexts. While the work developed from the specific context of a faith-based foundation, there are several tools and approaches that may be considered or adapted more broadly within philanthropy

Random walks and market efficiency in Chinese and Indian equity markets

Hypothesis of Market Efficiency is an important concept for the investors across the globe holding diversified portfolios. With the world economy getting more integrated day by day, more people are investing in global emerging markets. This means that it is pertinent to understand the efficiency of these markets. This paper tests for market efficiency by studying the impact of global financial crisis of 2008 and the recent Chinese crisis of 2015 on stock market efficiency in emerging stock markets of China and India. The data for last 20 years was collected from both Bombay Stock Exchange (BSE200) and the Shanghai Stock Exchange Composite Index and divided into four sub-periods, i.e. before financial crisis period (period-I), during recession (period-II), after recession and before Chinese Crisis (periodIII) and from the start of Chinese crisis till date (period- IV). Daily returns for the SSE and BSE were examined and tested for randomness using a combination of auto correlation tests, runs tests and unit root tests (Augmented Dickey-Fuller) for the entire sample period and the four sub-periods. The evidence from all these tests supports that both the Indian and Chinese stock markets do not exhibit weak form of market efficiency. They do not follow random walk overall and in the first three periods (1996 till the 2015) implying that recession did not impact the markets to a great extent, although the efficiency in percentage terms seems to be increasing after the global financial crisis of 2008

The AIM2 inflammasome is critical for innate immunity to Francisella tularensis.

Francisella tularensis, the causative agent of tularemia, infects host macrophages, which triggers production of the proinflammatory cytokines interleukin 1beta (IL-1beta) and IL-18. We elucidate here how host macrophages recognize F. tularensis and elicit this proinflammatory response. Using mice deficient in the DNA-sensing inflammasome component AIM2, we demonstrate here that AIM2 is required for sensing F. tularensis. AIM2-deficient mice were extremely susceptible to F. tularensis infection, with greater mortality and bacterial burden than that of wild-type mice. Caspase-1 activation, IL-1beta secretion and cell death were absent in Aim2(-/-) macrophages in response to F. tularensis infection or the presence of cytoplasmic DNA. Our study identifies AIM2 as a crucial sensor of F. tularensis infection and provides genetic proof of its critical role in host innate immunity to intracellular pathogens

Membrane insertion of anthrax protective antigen and cytoplasmic delivery of lethal factor occur at different stages of the endocytic pathway

The protective antigen (PA) of anthrax toxin binds to a cell surface receptor, undergoes heptamerization, and binds the enzymatic subunits, the lethal factor (LF) and the edema factor (EF). The resulting complex is then endocytosed. Via mechanisms that depend on the vacuolar ATPase and require membrane insertion of PA, LF and EF are ultimately delivered to the cytoplasm where their targets reside. Here, we show that membrane insertion of PA already occurs in early endosomes, possibly only in the multivesicular regions, but that subsequent delivery of LF to the cytoplasm occurs preferentially later in the endocytic pathway and relies on the dynamics of internal vesicles of multivesicular late endosomes

Development of an index to rank dairy females on expected lifetime profit

peer-reviewedThe objective of this study was to develop an index to rank dairy females on expected profit for the remainder of their lifetime, taking cognizance of both additive and nonadditive genetic merit, permanent environmental effects, and current states of the animal including the most recent calving date and cow parity. The cow own worth (COW) index is intended to be used for culling the expected least profitable females in a herd, as well as inform purchase and pricing decisions for trading of females. The framework of the COW index consisted of the profit accruing from (1) the current lactation, (2) future lactations, and (3) net replacement cost differential. The COW index was generated from estimated performance values (sum of additive genetic merit, nonadditive genetic merit, and permanent environmental effects) of traits, their respective net margin values, and transition probability matrices for month of calving, survival, and somatic cell count; the transition matrices were to account for predicted change in a cow’s state in the future. Transition matrices were generated from 3,156,109 lactation records from the Irish national database between the years 2010 and 2013. Phenotypic performance records for 162,981 cows in the year 2012 were used to validate the COW index. Genetic and permanent environmental effects (where applicable) were available for these cows from the 2011 national genetic evaluations and used to calculate the COW index and their national breeding index values (includes only additive genetic effects). Cows were stratified per quartile within herd, based on their COW index value and national breeding index value. The correlation between individual animal COW index value and national breeding index value was 0.65. Month of calving of the cow in her current lactation explained 18% of the variation in the COW index, with the parity of the cow explaining an additional 3 percentage units of the variance in the COW index. Females ranking higher on the COW index yielded more milk and milk solids and calved earlier in the calving season than their lower ranking contemporaries. The difference in phenotypic performance between the best and worst quartiles was larger for cows ranked on COW index than cows ranked on the national breeding index. The COW index is useful to rank females before culling or purchasing decisions on expected profit and is complementary to the national breeding index, which identifies the most suitable females for breeding replacements

Effects of memory load and distraction on performance and event-related slow potentials in a visuospatial working memory task

Brain electrical activity related to working memory was recorded at 15 scalp electrodes during a visuospatial delayed response task. Participants (N = 18) touched the remembered position of a target on a computer screen after either a 1 or 8 sec delay. These memory trials were compared to sensory trials in which the target remained present throughout the delay and response periods. Distracter stimuli identical to the target were briefly presented during the delay on 30% of trials. Responses were less accurate in memory than sensory trials, especially after the long delay. During the delay slow potentials developed that were significantly more negative in memory than sensory trials. The difference between memory and sensory trials was greater at anterior than posterior electrodes. On trials with distracters, the slow potentials generated by memory trials showed further enhancement of negativity whereas there were minimal effects on accuracy of performance. The results provide evidence that engagement of visuospatial working memory generates slow wave negativity with a timing and distribution consistent with frontal activation. Enhanced brain activity associated with working memory is required to maintain performance in the presence of distraction. © 1997 by the Massachusetts Institute of Technolog
