The Appeal of Protest Rhetoric: How Moral Entrepreneurs Recruit the Media into Moral Struggles
Whenever the news media feature brand-related moral struggles over issues such as ethicality, fairness, or sustainability, brands often find themselves in the position of the culprit. However, brands may also take the opposite position, that of a moral entrepreneur that proactively raises and addresses moral issues that matter to society. In this chapter, we present a case study of the Austrian shoe manufacturer Waldviertler, which staged a protest campaign against Austria’s financial market authorities (FMA) in the wake of the authorities demanding that the company closes its alternative (and illegal) consumer investment model after 10 years of operation. In response to this demand, the company organized protest marches, online petitions, and press conferences to reclaim the moral high ground for its financing model as a way out of the crunch following the global credit crisis and as a way to fight unfair administrative burdens. We present an interpretive analysis of brand communication material and media coverage that reveals how this brand used protest rhetoric on three levels – logos, ethos, and pathos – to reverse moral standards, to embody a rebel ethos, and to cultivate moral indignation. We also show how the media responded to protest rhetoric both with thematic coverage of context, trends, and general evidence, and with episodic coverage focusing on dramatic actions and the company owner’s charisma. We close with a discussion of how protestainment, the stylization of a leader figure, and marketplace sentiments can ensure sustained media coverage of moral struggles
Performance of Predictor Based Link Adaptation Algorithms
The presented paper deals with the link adaptation algorithms in mobile radio access networks based on Wideband Code Division Multiple Access (WCDMA). The mobile radio channel has a significant impact on the transmitted signal between User Equipment (UE) and Base Station (BS). The character of environment (e.g. number of received reflections) and increasing UE velocity cause unfavorable signal fadings, which have a major impact on the received signal. Due to this fact and the principle of WCDMA, fast power adaptation is essential for mobile radio access networks based on WCDMA. The prediction of mobile radio channel near-future state is one of the possible approaches how to span its unfavorable state. According to this assumption, we have improved the basic link adaptation algorithm (used to control properties of transmitter) to predictor based link adaptation algorithm. This contribution comprises the performance of basic link adaptation algorithm and predictor based algorithms, which support both variable (multi-bit) and fixed (singlebit) power steps to modify transmitter output power level. The link adaptation algorithms were simulated under various average UE velocities in urban environment. New algorithms were designed to increase the efficiency of data transmission in uplink direction
Mutual Interference Models for CDMA Mobile Communication Networks
Nowadays we are witnesses of a huge development one of the most progressive communication technology - mobile networks. The main problem in these networks is an elimination of the mutual interference, which, mainly in non-orthogonal CDMA networks, is the principal obstacle for reaching high transmission rates The aim of this contribution is to give simplified view to mutual interference models for orthogonal and non-orthogonal CDMA networks. The contribution is intended mainly for PhD. students to help them to obtain an orientation in such a complicated areas, as the interference models for CDMA networks are
Power Control Imperfection in CDMA Systems with Adaptive Antennas
This paper deals with a simulation of cellular CDMA system using base station adaptive antennas. The model assumes two tiers area, four types of antennas, lognormal shadowing corresponding to three types of environments and perfect power control or two values of power control error, respectively. The capacity of system in up-link is evaluated by a number of mobile stations with higher signal to interference ratio than threshold with given outage probability
Observed spatial variability of boundary-layer turbulence over flat, heterogeneous terrain
In spring 2013, extensive measurements with multiple Doppler lidar systems were performed. The instruments were arranged in a triangle with edge lengths of about 3 km in a moderately flat, agriculturally used terrain. For six mostly cloud-free convective days, vertical velocity variance profiles were compared for the three locations. On the average over all considered cases, differences between variances at different sites were about three times higher than between those derived from measurements by different lidars at the same site. For all investigated averaging periods between 10 min and 4 h, the differences were not significant on the average when considering the statistical error. However, statistically significant spatial differences were found in several individual cases. These could not be explained by the existing surface heterogeneity.
In some cases, nearby energy balance stations provided surface fluxes that were not suitable for scaling the variance profiles. Weighted-averaged values proved to be more applicable, but even then, the scaled profiles showed a large scatter for each location. Therefore, it must be assumed that the intensity of turbulence is not always well-determined by the local heat supply at the Earth\u27s surface. Instead, a certain dependency of turbulence characteristics on mean wind speed and direction was found: thermals were detected that travelled from one site to the other with the mean wind when the travel time was shorter than the large-eddy turnover time. At the same time, no thermals passed for more than two hours at a third site that was located perpendicular to the mean wind direction in relation to the first two sites. Subsidence prevailing in the surroundings of thermals advected with the mean wind can thus partly explain significant spatial variance differences existing for several hours
A dataflow IR for memory efficient RIPL compilation to FPGAs
Field programmable gate arrays (FPGAs) are fundamentally different to fixed processors architectures because their memory hierarchies can be tailored to the needs of an algorithm. FPGA compilers for high level languages are not hindered by fixed memory hierarchies. The constraint when compiling to FPGAs is the availability of resources.
In this paper we describe how the dataflow intermediary of our declarative FPGA image processing DSL called RIPL (Rathlin Image Processing Language) enables us to constrain memory. We use five benchmarks to demonstrate that memory use with RIPL is comparable to the Vivado HLS OpenCV library without the need for language pragmas to guide hardware synthesis. The benchmarks also show that RIPL is more expressive than the Darkroom FPGA image processing language
Observed spatiotemporal variability of boundary-layer turbulence over flat, heterogeneous terrain
In the spring of 2013, extensive measurements with multiple Doppler lidar systems were performed. The instruments were arranged in a triangle with edge lengths of about 3 km in a moderately flat, agriculturally used terrain in northwestern Germany. For 6 mostly cloud-free convective days, vertical velocity variance profiles were calculated. Weighted-averaged surface fluxes proved to be more appropriate than data from individual sites for scaling the variance profiles; but even then, the scatter of profiles was mostly larger than the statistical error. The scatter could not be explained by mean wind speed or stability, whereas time periods with significantly increased variance contained broader thermals. Periods with an elevated maximum of the variance profiles could also be related to broad thermals. Moreover, statistically significant spatial differences of variance were found. They were not influenced by the existing surface heterogeneity. Instead, thermals were preserved between two sites when the travel time was shorter than the large-eddy turnover time. At the same time, no thermals passed for more than 2 h at a third site that was located perpendicular to the mean wind direction in relation to the first two sites. Organized structures of turbulence with subsidence prevailing in the surroundings of thermals can thus partly explain significant spatial variance differences existing for several hours. Therefore, the representativeness of individual variance profiles derived from measurements at a single site cannot be assumed
Burden of micronutrient deficiencies by socio-economic strata in children aged 6 months to 5 years in the Philippines
Background: Micronutrient deficiencies (MNDs) are a chronic lack of vitamins and minerals and constitute a huge public health problem. MNDs have severe health consequences and are particularly harmful during early childhood due to their impact on the physical and cognitive development. We estimate the costs of illness due to iron deficiency (IDA), vitamin A deficiency (VAD) and zinc deficiency (ZnD) in 2 age groups (6-23 and 24-59 months) of Filipino children by socio-economic strata in 2008.
Methods: We build a health economic model simulating the consequences of MNDs in childhood over the entire lifetime. The model is based on a health survey and a nutrition survey carried out in 2008. The sample populations are first structured into 10 socio-economic strata (SES) and 2 age groups. Health consequences of MNDs are modelled based on information extracted from literature. Direct medical costs, production losses and intangible costs are computed and long term costs are discounted to present value.
Results: Total lifetime costs of IDA, VAD and ZnD amounted to direct medical costs of 30 million dollars, production losses of 618 million dollars and intangible costs of 122,138 disability adjusted life years (DALYs). These costs can be interpreted as the lifetime costs of a 1-year cohort affected by MNDs between the age of 6–59 months. Direct medical costs are dominated by costs due to ZnD (89% of total), production losses by losses in future lifetime (90% of total) and intangible costs by premature death (47% of total DALY losses) and losses in future lifetime (43%). Costs of MNDs differ considerably between SES as costs in the poorest third of the households are 5 times higher than in the wealthiest third.
Conclusions: MNDs lead to substantial costs in 6-59-month-old children in the Philippines. Costs are highly concentrated in the lower SES and in children 6-23 months old. These results may have important implications for the design, evaluation and choice of the most effective and cost-effective policies aimed at the reduction of MNDs
