Methodological Challenges in Estimating the Lifetime Medical Care Cost Externality of Obesity

There is a great deal of variability in estimates of the lifetime medical care cost externality of obesity, partly due to a lack of transparency in the methodology behind these cost models. Several important factors must be considered in producing the best possible estimate, including age-related weight gain, differential life expectancy, identifiability, and cost model selection. In particular, age-related weight gain represents an important new component to recent cost estimates. Without accounting for age-related weight gain, a study relies on the untenable assumption that people remain the same weight throughout their lives, leading to a fundamental misunderstanding of the evolution and development of the obesity crisis. This study seeks to inform future researchers on the best methods and data available both to estimate age-related weight gain and to accurately and consistently estimate obesity’s lifetime external medical care costs. This should help both to create a more standardized approach to cost estimation as well as encourage more transparency between all parties interested in the question of obesity’s lifetime cost and, ultimately, evaluating the benefits and costs of interventions targeting obesity at various points in the life course.

“I Lived without Seeing These Art Works”: (Albanian) Socialist Realism and/against Contemporary Art

This article looks closely at the inclusion of Albanian Socialist Realism in one of renowned Swiss curator Harald Szeemann's last exhibitions, Blood & Honey: The Future's in the Balkans (Essl Museum, Vienna, 2003). In this exhibition, Szeemann installed a group of around 40 busts created during the socialist era in Albania, which he had seen installed at the National Gallery of Arts in Tirana. This installation of sculptures was part of an exhibition entitled Homo Socialisticus, curated by Gëzim Qëndro, and Szeemann deployed it as a generalized foil for “subversive” postsocialist contemporary art included in Blood & Honey. The Homo Socialisticus sculptures occupied a prominent place in the exhibition both spatially and rhetorically, and this article examines how we might read Blood & Honey—and the socialist past in general—through Szeemann's problematic incorporation of this collection of works in one of the key Balkans-oriented exhibitions staged in the early 2000s. The article argues that understanding how Szeemann misread—and discursively oversimplified—Albanian Socialist Realism can help us see not only the continued provincialization of Albania in the contemporary global art world, but more importantly the fundamental misunderstanding of Socialist Realism as a historical phenomenon and a precursor to contemporary geopolitical cultural configurations

Knick and the Elephant in the Courtroom

In Knick v. Township of Scott, the Supreme Court corrected one of the most egregious and inexplicable blunders of its 230-year history. For more than three decades, plaintiffs who alleged a violation of the Takings Clause by state or local governments were barred from suing for compensation in federal court. The source of this prohibition was Justice Blackmun’s 1985 opinion in Williamson County Regional Planning Commission v. Hamilton Bank of Johnson City—a decision that most scholars and practitioners believe rested on a fundamental misunderstanding of both constitutional text and legal procedure.

Perception and Use of Economic Thresholds Among Farmers and Agricultural Professionals: A Case Study on Soybean Aphid in Minnesota

Economic thresholds (ETs) are a foundational principle of integrated pest management but are not always widely accepted by farmers and agricultural professionals. This article reports on a survey of Minnesota farmer and agricultural professional perceptions of the ET for soybean aphid, Aphis glycines Matsumura (Hempitera: Aphididae). We discuss insights for Extension programs on how to frame the importance of thresholds and teach stakeholders to use them effectively. Key takeaways include farmers and agricultural professionals often worry about combined effects of insect, disease, and physiological pressures, whereas effects of interactions with these other stressors are seldom discussed in educational outreach. Across groups, there is a fundamental misunderstanding about the difference between ETs and economic injury level. Many survey participants reported believing in the ET but lacked the time and capacity to fully implement it. Sales agronomists and farmers were the least likely groups to trust the university-determined soybean aphid ET, whereas commercial pesticide applicators and independent consultants were the most likely groups to trust it. Based on these results, we recommend adapting communication about ETs based on the target audience to address common misconceptions and barriers to ET use that are unique to each group.

Apparent negative density-dependent dispersal in tsetse (Glossina spp) is an artefact of inappropriate analysis

Analysis of genetic material from field-collected tsetse (Glossina spp) in ten study areas has been used to predict that the distance (δ) dispersed per generation increases as effective population densities (De) decrease, displaying negative density dependent dispersal (NDDD). This result is an artefact arising primarily from errors in estimates of S, the area occupied by a subpopulation, and thereby in De, the effective subpopulation density. The fundamental, dangerously misleading, error lies in the assumption that S can be estimated as the area (Ŝ) regarded as being covered by traps. Errors in the estimates of δ are magnified because variation in estimates of S is greater than for all other variables measured, and accounts for the greatest proportion of variation in δ. The errors result in anomalously high correlations between δ and S, and the appearance of NDDD, with a slope of −0.5 for the regressions of log(δ) on log(e), even in simulations where dispersal has been set as density independent. A complementary mathematical analysis confirms these findings. Improved error estimates for the crucial parameter b, the rate of increase in genetic distance with increasing geographic separation, suggest that three of the study areas should have been excluded because b is not significantly greater than zero. Errors in census population estimates result from a fundamental misunderstanding of the relationship between trap placement and expected tsetse catch. These errors are exacerbated through failure to adjust for variations in trapping intensity, trap performance, and in capture probabilities between geographical situations and between tsetse species. Claims of support in the literature for NDDD are spurious. There is no suggested explanation for how NDDD might have evolved. We reject the NDDD hypothesis and caution that the idea should not be allowed to influence policy on tsetse and trypanosomiasis control.Author summaryGenetic analysis of field-sampled tsetse (Glossina spp) has been used to suggest that, as tsetse population densities decrease, rates of dispersal increase – displaying negative density dependent dispersal (NDDD). It is further suggested that NDDD might apply to all tsetse species and that, consequently, tsetse control operations might unleash enhanced invasion of areas cleared of tsetse, prejudicing the long-term success of control campaigns. We demonstrate that NDDD in tsetse is an artefact consequent on multiple errors of analysis and interpretation. The most serious of these errors stems from a fundamental misunderstanding of the way in which traps sample tsetse, resulting in huge errors in estimates of the areas sampled by the traps, and occupied by the subpopulations being sampled. Errors in census population estimates are made worse through failure to adjust for variations in trapping intensity, trap performance, and in capture probabilities between geographical situations, and between tsetse species. The errors result in the appearance of NDDD, even in modelling situations where rates of dispersal are expressly assumed independent of population density. We reject the NDDD hypothesis and caution that the idea should not be allowed to influence policy on tsetse and trypanosomiasis control.

Adverse Childhood Experiences and Social Work: Relationship-based Practice Responses

Individuals with higher numbers of adverse childhood experiences (ACEs) have been found to be overrepresented amongst users of social services. This poses challenges for service providers in seeking ways to incorporate knowledge about ACEs in the calibration of service provision, and for social workers as to how they might use such knowledge in their day-to-day practice. The key contribution of this article is as a position piece that aims to map out a possible response to the ACEs evidence from social work. Practice needs to be informed by an understanding of the causes and consequences of trauma in the lives of individuals and groups. Short-term interventions based on proximal causes have resulted in a fundamental misunderstanding as to the aetiology of the problems experienced and to the types of interventions required to facilitate their amelioration. ACEs research offers a new understanding of how connecting trajectories are formed and maintained in ways that integrate biological, psychological and sociological concepts. In this article, we have made selective use of key texts and studies in the social work literature to illustrate how relationship-based social work may be appropriated and repurposed to align with interventions to mitigate the effects of ACEs.

COVID-19 Pandemic Highlights the Need for Teaching Health Communication to Public Health Students

The COVID-19 pandemic precipitated a deluge of scholarly publications and scientific outreach. Information about the novel coronavirus has spread rapidly through both traditional news and social media platforms. Timely scientific literature is paramount to public health, but it must be paired with nuanced and tailored outreach and messaging. Despite being a core public health competency, not all public health science students receive training in these skills. The media response to the COVID-19 pandemic reveals a fundamental misunderstanding by the general public about the scientific process and cultivates a narrative that too often places blame on individuals for structural inequities. An influx of research without audience-appropriate interpretations, coupled with a lack of representation in the news media, threatens to erode trust in science. To address these challenges, schools and programs of public health might reflect on their curricula and consider placing a greater emphasis on health communication.

Summary Excerpt from Question That Matter: An Invitation to Philosophy

The purpose of this short excerpt is to provide general introduction of philosophy for non-philosophy disciplined students. This exclusive excerpt will minimize fundamental misunderstanding of philosophy among students and higher institutions graduate students. Philosophy is not talking of trash events. It does not mean ordinary dialogue rather it is hard science which typically has its own scientific procedure and scientific investigation. For the purpose, I, roughly, summarized Miller’s unrevised edition book titled as “Question That Matter: An Invitation to Philosophy (1984)”.

A refutation of “a refutation of universal grammar”(Lin, f. 2017. Lingua 193. 1–22.)

Lin (2017), according to the author, “offers a refutation of Chomsky’s Universal Grammar (UG) from a novel perspective”. Unfortunately, “novel” does not mean logical or valid. On the contrary, as I will show in this refutation of Lin’s refutation, there is a profound and fundamental misunderstanding in Lin’s interpretation of UG. His refutation only proves his superficial understanding of the questions raised and discussed, which nevertheless are worth discussing and explaining. I take each of Lin’s arguments in turn and attempt to show why they are not well founded, either because of flaws in his argumentation or because of a careful consideration of the available empirical evidence. In the first section I show that Lin’s refutation of UG is illogical in that he confuses UG as a theoretical construct and as a reality entity, which renders his own analysis self-contradictory. The second section aims to examine in detail the so-called novelty of Lin’s refutation, proving that his refutation is unscientific. The third section offers a point-to-point refutation of his arguments presented in the third section of his paper. The fourth section furthermore points out several misunderstandings of previous studies against Chomsky and UG. The last section concludes the paper.
