Evaluasi Komunikasi: Studi Kasus Pelaksanaan Program Pemberdayaan Masyarakat Penggiat Anti Narkoba Oleh Bnn Jakarta Timur

The problem of drug abuse and trafficking is increasingly becoming a problem for every country worldwide, including Indonesia. DKI Jakarta, as the state capital, ranks third nationally in narcotics abuse, with a trial use prevalence rate reaching 4.9%. In this study, researchers will focus on evaluating communication programs carried out through technical guidance carried out by BNN for anti-drug activists in the educational environment. We utilized the four stages of program planning by Cutlip, Center and Broom, to get a picture of the situation, program planning and form of communication, which will elaborate further on aspects of communication evaluation based on the Yardstick evaluation model..

Brief communication: Evaluation of the snow cover detection in the Copernicus High Resolution Snow & Ice Monitoring Service

The High Resolution Snow &amp; Ice Monitoring Service was launched in 2020 to provide near-real-time, pan-European snow and ice information at 20 m resolution from Sentinel-2 observations. Here we present an evaluation of the snow detection using a database of snow depth observations from 1764 stations across Europe over the hydrological year 2016–2017. We find a good agreement between both datasets with an accuracy (proportion of correct classifications) of 94 % and kappa of 0.81. More accurate (+6 % kappa) retrievals are obtained by excluding low-quality pixels at the cost of a reduced coverage (−13 % data).

Counterintuitive Pseudoscience Propagates by Exploiting the Mind’s Communication Evaluation Mechanisms

Epidemiological models of culture posit that the prevalence of a belief depends in part on the fit between that belief and intuitions generated by the mind’s reliably developing architecture. Application of such models to pseudoscience suggests that one route via which these beliefs gain widespread appeal stems from their compatibility with these intuitions. For example, anti-vaccination beliefs are readily adopted because they cohere with intuitions about the threat of contagion. However, other varieties of popular pseudoscience such as astrology and parapsychology contain content that violates intuitions held about objects and people. Here, we propose a pathway by which “counterintuitive pseudoscience” may spread and receive endorsement. Drawing on recent empirical evidence, we suggest that counterintuitive pseudoscience triggers the mind’s communication evaluation mechanisms. These mechanisms are hypothesized to quarantine epistemically-suspect information including counterintuitive pseudoscientific concepts. As a consequence, these beliefs may not immediately update conflicting intuitions and may be largely restricted from influencing behavior. Nonetheless, counterintuitive pseudoscientific concepts, when in combination with intuitively appealing content, may differentially draw attention and memory. People may also be motivated to seek further information about these concepts, including by asking others, in an attempt to reconcile them with prior beliefs. This in turn promotes the re-transmission of these ideas. We discuss how, during this information-search, support for counterintuitive pseudoscience may come from deference to apparently authoritative sources, reasoned arguments, and the functional outcomes of these beliefs. Ultimately, these factors promote the cultural success of counterintuitive pseudoscience but explicit endorsement of these concepts may not entail tacit commitment.

Brief communication: Evaluation of multiple density-dependent empirical snow conductivity relationships in East Antarctica

Nine density-dependent empirical thermal conductivity relationships for firn were compared against data from three automatic weather stations at climatically different sites in East Antarctica (Dome A, Eagle, and LGB69). The empirical relationships were validated using a vertical, 1D thermal diffusion model and a phase-change-based firn diffusivity estimation method. The best relationships for the abovementioned sites were identified by comparing the modeled and observed firn temperature at a depth of 1 and 3 m, and from the mean heat conductivities over two depth intervals (1–3 and 3–10 m). Among the nine relationships, that proposed by Calonne et al. (2011) appeared to show the best performance. The density- and temperature-dependent relationship given in Calonne et al. (2019) does not show clear superiority over other density-dependent relationships. This study provides a useful reference for firn thermal conductivity parameterizations in land modeling or snow–air interaction studies on the Antarctica ice sheet.

Evaluation of Science Communication: Current Practices, Challenges, and Future Implications

Scientifically substantiated evaluations are pivotal to ensuring the effectiveness and improvement of the growing number of science communication projects. Yet current evaluation practices are still lacking in various respects. Based on a systematic review of evaluation reports, an online survey of, as well as discussion rounds with science communication practitioners in the German-speaking countries, we discuss three main challenges of science communication evaluation: (1) There is a conflation of impact goals and measurable project objectives as well as a lack of precise definitions of objectives and target groups, which complicates the assessment of the projects' success. (2) Although many evaluations highlight the impact-oriented interest of those responsible, the methods chosen rarely allow scientifically valid evaluations of effects. The lack of comparative reference points and the partially unsuitable use of self-report measures are key issues in this regard. (3) The fact that few evaluation processes are made transparent and that formative evaluation designs are a rarity indicates a tendency to understand evaluations as the final ‘success story’ of a project rather than a learning process. This stands in the way of a constructive discussion of the actual impact of science communication. Our exploratory insights contribute to an understanding of the weaknesses of science communication evaluation and needs in the field. They also provide impulses for future improvements in the field for the stakeholders in practice, research, funding, and science management.
