Mechanical tasting: sensory science and the flavorization of food production

The paper narrates the history of “texturometers”, devices that imitate the human biting mechanism and are used by food scientists in experiments on food texture. Two interrelated processes, characteristic of the emergence of industrialized food production in the twentieth century, are examined through this history of mechanical tasting. First, the paper surveys the pervasive project of transforming the phenomenological qualities of flavor and food texture into robust “objective” and “standardized” data. In constructing and using biomimetic texturometers, food sensory scientists attempted to translate texture qualities such as tenderness, crispness, crunch and chewiness into codified properties by producing formal definitions and graphical representations – an example of how the pursuit of objectivity and standardized knowledge coevolved with the rise of mass production and the emergence of sensory sciences. Secondly, the texturometers are related to an overall “flavorization”; that is, a historical process by which the complexes of sensory impressions became increasingly important for the production and consumption of food in late-modern industrialized societies.

Women's entrepreneurship,neoliberalism and economic justice in the postfeminist era: A discourse analysis of policy change in Sweden

Since the early 1990s, there has been investment in women's entrepreneurship policy (WEP) in Sweden, which continued until 2015. During the same period, Sweden assumed neoliberal policies that profoundly changed the position of women within the world of work and business. The goals for WEP changed as a result, from entrepreneurship as a way to create a more equal society, to the goal of unleashing women's entrepreneurial potential so they can contribute to economic growth. To better understand this shift we approach WEP as a neoliberal governmentality which offers women ‘entrepreneurial’ or ‘postfeminist’ subject positions. The analysis is inspired by political theorist Nancy Fraser who theorized the change as the displacement of socioeconomic redistribution in favour of cultural recognition, or identity politics. We use Fraser's concepts in a discourse analysis of Swedish WEP over two decades, identifying two distinct discourses and three discursive displacements. Whilst WEP initially gave precedence to a radical feminist discourse that called for women's collective action, this was replaced by a postfeminist neoliberal discourse that encouraged individual women to assume an entrepreneurial persona, start their own business, compete in the marketplace and contribute to economic growth. The result was the continued subordination of women business owners, but it also obscured or rendered structural problems/solutions, and collective feminist action, irrelevant.     

On Unimodal Regression in the Exponential Family

In this article, we discuss statistical methods for curve-estimation under the assumption of unimodality for variables with distributions belonging to the two-parameter exponential family with known or constant dispersion parameter. An important special case is a one-parameter distribution. We suggest a nonparametric method based on monotonicity properties. The method is applied to Swedish data on laboratory verified diagnoses of influenza and data on inflation from an episode of hyperinflation in Bulgaria.     

“Better safe than sorry”—Reasons for consulting care due to decreased fetal movements

Background

Experience of reduced fetal movements is a common reason for consulting health care in late pregnancy. There is an association between reduced fetal movements and stillbirth.

Democracy,Redistribution, and Political Participation: Evidence From Sweden 1919–1938

In this paper, we compare how two different types of political regimes—direct versus representative democracy—redistribute income toward the relatively poor segments of society after the introduction of universal and equal suffrage. Swedish local governments are used as a testing ground since this setting offers a number of attractive features for a credible impact evaluation. Most importantly, we exploit the existence of a population threshold, which partly determined a local government's choice of democracy to implement a regression‐discontinuity design. The results indicate that direct democracies spend 40–60 percent less on public welfare. Our interpretation is that direct democracy may be more prone to elite capture than representative democracy since the elite's potential to exercise de facto power is likely to be greater in direct democracy after democratization.     

Optimal design in average for inference in generalized linear models

This paper considers the problem of optimal design for inference in Generalized Linear Models, when prior information about the parameters is available. The general theory of optimum design usually requires knowledge of the parameter values. These are usually unknown and optimal design can, therefore, not be used in practice. However, one way to circumvent this problem is through so-called “optimal design in average”, or shortly, “ave optimal”. The ave optimal design is chosen to minimize the expected value of some criterion function over a prior distribution. We focus our interest on the aveD _A-optimality, including aveD- and avec-optimality and show the appropriate equivalence theorems for these optimality criterions, which give necessary conditions for an optimal design. Ave optimal designs are of interest when e.g. a factorial experiment with a binary or a Poisson response in to be conducted. The results are applied to factorial experiments, including a control group experiment and a 2×2 experiment.     

Methodical aspects of text testing in a driving simulator

A test with 30 test persons was conducted in a driving simulator. The test was a concept exploration and comparison of existing user interaction technologies for text message handling with focus on traffic safety and experience (technology familiarity and learning effects). Focus was put on methodical aspects how to measure and how to analyze the data. Results show difficulties with the eye tracking system (calibration etc.) per se, and also include the subsequent raw data preparation. The physical setup in the car where found important for the test completion.
