Color image reduction by minimizing penalty functions

In image processing, particularly in image reduction, averaging aggregation functions play an important role. In this work we study the aggregation of color values (RGB) and we present an image reduction algorithm for RGB color images. For this purpose, we define and study aggregation functions and penalty functions in product lattices. We show how the arithmetic mean and the median can be obtained by minimizing specific penalty functions. Moreover, we study other penalty functions and we show that, in general, aggregation functions on product lattices do not coincide with the cartesian product of the corresponding aggregation functions. Finally, we make an experimental study where we test our reduction algorithm and we analyze the stability of the penalty functions in images affected by noise.

Globalisation, television and developmental agenda

Theorising the impact of foreign and private television in India since 1991, does not neatly fit into the old debates about one way flow of news and information as reflected in the demand for the New World Information and Communication Order in the 1970s and early 1980s. In the 1990s, Indian society was invaded from the skies by a number of satellite television signals. However, did this advent of satellite television, vis à vis foreign and private television channels, lead to one way flow of information and entertainment programs from the Western world? Or, did it lead to rapid growth of Indian television industry, resulting in exponential increase in quality and quantity of television programs available to audience?

This paper argues that the de facto de-regulation of the television media since 1991 has led to an enviable growth in local production of programs for more than 450 channels, estimated to be worth Rs30 billion (AS$1 billion), thereby providing an increased level of opportunity for articulation of Indian local stories and culture. This way, the Indian television industry seems to have come full circle – where television, which was launched in the country as a means of development and education but became complacent and the government’s mouth-piece, finally in the past decade-and-a-half has grown sufficiently to potentially provide an outlet for diverse local expressions thereby revitalising democracy in India.

Competition and television news in India : a content analysis

In India, not unlike some other developing countries, ruling parties have used public service broadcasters to propagate their virtues, adversely affecting the broadcasters' image as a credible news media. The Indian public service broadcaster. Doordarshan,
which has been besieged by increased competition and government-imposed demandfor selfsufficiency in recent years, continues to struggle to shed its image as a government mouthpiece despite being run by an independent corporation. This article
presents a content analysis of news programs broadcast by Doordarshan and a foreign television network. Star News. The study examines the differences and similarities between Doordarshan and Star TV's prime time news programs broadcast at the turn ofthe century, almost a decade after the advent ofcommercial television in India broke the public service broadcaster's monopoly in the country.

Life during wartime : sexuality, recruitment and reality television

In 2010, Defence Force Recruiting (DFR) Navy Marketing entered into a media sponsorship package with the Australian version of the reality TV show So You Think You Can Dance (SYTYCD): Footage of the day aired on national television on SYTYCD and weekly ‘dancer bootcamp’ sessions training the dancers in Navy values featured on a dedicated and branded Navy section of the official SYTYCD website. This article analyses the Navy’s SYTYCD ‘integration opportunities’ to consider the role of reality television in the redefinition of the defence forces as a training and vocational pathway for young people. Underpinning such considerations is the conceptualization of the work of reality television through the prism of public and popular pedagogies. Taking sexuality as a focal point, the article will reflect on efforts to lift recruitment through an emphasis on the incorporation of diversity. Reading the work of Jasbir Puar against the Australian ‘archive’ of integration opportunities, this article contributes to queer critiques of homonormative and homonationalist tendencies in contemporary politics.

An analysis of potential barriers and enablers to regulating the television marketing of unhealthy foods to children at the state government level in Australia

Background In Australia there have been many calls for government action to halt the effects of unhealthy food marketing on children's health, yet implementation has not occurred. The attitudes of those involved in the policy-making process towards regulatory intervention governing unhealthy food marketing are not well understood. The objective of this research was to understand the perceptions of senior representatives from Australian state and territory governments, statutory authorities and non-government organisations regarding the feasibility of state-level government regulation of television marketing of unhealthy food to children in Australia.

Method Data from in-depth semi-structured interviews with senior representatives from state and territory government departments, statutory authorities and non-government organisations (n=22) were analysed to determine participants' views about regulation of television marketing of unhealthy food to children at the state government level. Data were analysed using content and thematic analyses.

Results Regulation of television marketing of unhealthy food to children was supported as a strategy for obesity prevention. Barriers to implementing regulation at the state level were: the perception that regulation of television advertising is a Commonwealth, not state/territory, responsibility; the power of the food industry and; the need for clear evidence that demonstrates the effectiveness of regulation. Evidence of community support for regulation was also cited as an important factor in determining feasibility.

Conclusions The regulation of unhealthy food marketing to children is perceived to be a feasible strategy for obesity prevention however barriers to implementation at the state level exist. Those involved in state-level policy making generally indicated a preference for Commonwealth-led regulation. This research suggests that implementation of regulation of the television marketing of unhealthy food to children should ideally occur under the direction of the Commonwealth government. However, given that regulation is technically feasible at the state level, in the absence of Commonwealth action, states/territories could act independently. The relevance of our findings is likely to extend beyond Australia as unhealthy food marketing to children is a global issue.

Need for a cohesive television policy in India

The Indian television industry has been dramatically transformed since 1991 when foreign television channels such as STAR TV and others began beaming their programs into Indian households from foreign soil. The impact of the exponential growth in television channelsi, television viewers and the television software industry in India between 1991 and 2006 has been well documented (Rodrigues, 1998, 2005). This paper analyses whether the Indian government’s television policy during the past decade and a half adequately met the challenge of the entry of private and foreign channels into Indian homes. The paper also makes a set of recommendations to the Government of India with regards to its television policy so that this popular medium can achieve its potential as a catalyst for social change in India (NAMEDIA, 1986).

Correlates of change in adults’ television viewing time : a four-year follow-up study

Purpose: Adults tend to increase their television (TV) viewing time as they age, but little is known about attributes associated with change in TV viewing over time. This study examined individual, social, and environmental correlates of change in TV viewing time for 4 yr.

Methods: Adult participants (n = 897) from a longitudinal epidemiological study in Adelaide, Australia, reported TV viewing time at baseline (2003–2004) and at follow- up (2007–2008). Generalized linear modeling was used to examine correlates of change in TV viewing time.

Results: The mean TV viewing time increased from 112 to 116 min·d-1 from baseline to follow-up. Adjusted for TV viewing time at baseline, having a tertiary education was associated with a 13% lower TV time at follow-up (P = 0.007). Each additional hour of occupational and transport physical activity at baseline was associated with a 2% and 7% lower TV viewing at follow-up (P = 0.031 and P = 0.023, respectively). For men, an additional hour of domestic physical activity was associated with a 7% higher TV viewing time at follow-up (P = 0.006). A significant neighborhood walkability × working status interaction (P = 0.035) indicated that, for those who were not working, living in a highly walkable neighborhood was associated with a 23% lower TV viewing time at follow-up (P = 0.003).

Conclusions: Adults with lower educational attainment, adults with lower occupational and transport physical activity, men with higher domestic physical activity, and nonworking adults living in lowly walkable neighborhoods were at higher risk of increase in TV viewing time. Interventions should target multiple variables at the individual, social, and environmental levels to address age-related increases in TV viewing time.

Television viewing time of colorectal cancer survivors is associated prospectively with quality of life

Objective : To examine prospective associations of television viewing time with quality of life, following a colorectal cancer diagnosis.

Methods : One thousand, nine hundred and sixty-six colorectal cancer survivors were recruited through the Queensland Cancer Registry. Interviews were conducted at 5, 12, 24, and 36 months post-diagnosis. Generalized linear mixed models estimated the effects of television viewing time on quality of life.

Results : Participants who watched ≥5 h of television per day had a 16% lower total quality of life score than did participants reporting ≤2 h per day. Deleterious associations of television viewing time were found with all quality of life subscales: functional well-being showed the strongest association (23% difference in quality of life scores between highest and lowest television viewing categories), and social well-being the weakest association (6% difference). Participants who increased their television viewing by one category (e.g., ≤2 h, increasing to 3–4 h per day) had a proportional decrease of some 6% in their quality of life score (intra-individual effect).

Conclusions : The deleterious associations of television viewing time with quality of life were clinically significant and consistent over time. Decreasing sedentary behavior may be an important behavioral strategy to enhance the quality of life of cancer survivors.

Interspecific differences in the Diel Vertical Migration of Marine Copepods : the Implications of size, color, and morphology

Samples collected by continuous plankton recorders (CPRs) between 1948 and 1992 were used to describe the diel vertical migration (DVM) behavior of 41 copepod taxa in the northeast Atlantic between 45 and 55?N and 11 and 31?W. A total of 13,622 samples, each representing - 18.5 km (10 nm) of tow, were analyzed. Since CPRs are towed in near-surface waters, taxa that exhibit DVM occur predominantly in samples taken at night. Larger taxa showed significantly stronger DVM, with body size explaining 47% of the intertaxa variation in DVM. For small taxa (< 1 mm wide) the residual variation in DVM was correlated with carotenoid pigment levels but not with body morphology, with more heavily pigmented taxa exhibiting DVM. For larger taxa (> 1 mm wide) the residual variation in DVM was correlated with body morphology but not with carotenoid pigment levels, with more elongate copepods not exhibiting DVM.

Lying idiots: reality television & lie to me

This article addresses perhaps the key question for Television Studies: Who does television think you are? It argues that Reality Television answers this question by producing its viewers as, in the Classical Greek sense, idiots (meaning private and ignorant persons). Idiots are the perfect target for the advertising dollar that supports commercial television production. As Reg Grundy observes, Reality Television is anything but reality. With its tight framings of reality, it paradoxically operates to sever the viewing self from reality—from the “truth” of life. Lie to Me is the type of television we are left with after the demise of Reality Television. Lie to Me makes us self-conscious, in the strongest sense, and thus sustains the mission of Reality Television. By dragging the notion of reality into its self-serving fictions, it puts the viewer into the dangerous position of being unable to lie to television. If Reality Television constrained reality to falsity, Lie to Me implicates the viewer in the zone where falsity transforms into reality. Lastly, this article enquires into the possibilities, in today’s television ecology, for a mode of TV citizenship that would counter the abject viewing position of the consumerist idiot.

Talking culture? Egalitarianism, color-blindness and racism in Australian elementary schools

This study examines egalitarianism as an ethnic-racial socialization message used by teachers with 8-12 year old children in four socio-demographically diverse elementary schools in Melbourne, Australia. The three main types of egalitarian messages identified are i) procedural-justice color-blindness, ii) distributive-justice color-blindness and iii) colormuteness, and each is explored in relation to how teachers talk to children about racial, ethnic and cultural diversity, and racism. We conclude that teacher confidence and capability, and to a lesser degree, school context, influenced the types of egalitarian messages used about diversity and the extent to which teachers had explicit and critical discussions about racism.
