Incomplete probability assessments in decision analysis

Summary In analysing a decision problem, in a situation ofpartial knowledge, a decision maker may be reluctant to assign acomplete probability distribution on the relevant states of nature. In order to face this difficulty, several methods, based onindeterminate probabilities or probabilityintervals, have been proposed in the literature. In this paper, arguing that it is meaningless to judge probabilistic assessments ascorrect orwrong, it is maintained that onlycoherence has anobjective andsignificant role. Then to overcome practical difficulties, an approach based on thesubjective methodology and on the use ofnumerical andqualitative probabilities, is outlined.     

Bird in hand: How experience makes nature

It is almost a truism that nature is social, but by what means is nature made social at the level of the interactional encounter? While the transformation of society/nature relationships is often approached through the problematic of distance, and at the scale of macro-historical transformation, this article uses a conflict between American birdwatchers and ornithologists over scientific “collecting” (literally, the killing of birds) to examine the processes through which individuals come to know nature, and come to know it so differently. With John Dewey’s (1958 [1925]) “experience” as the unit of analysis, I trace changes in each group’s experience with birds over the past century; the phenomenology of the resulting encounters; and the understanding that emerges from each in order to understand (1) how, empirically, these two very different loves of birds are formed, and (2) knowledge of nature as an affective sensibility shaped by experiences of closeness.     

Pivotal Quantities Based on Sequential Data: A Bootstrap Approach

A bootstrap algorithm is provided for obtaining a confidence interval for the mean of a probability distribution when sequential data are considered. For this kind of data the empirical distribution can be biased but its bias is bounded by the coefficient of variation of the stopping rule associated with the sequential procedure. When using this distribution for resampling the validity of the bootstrap approach is established by means of a series expansion of the corresponding pivotal quantity. A simulation study is carried out using Wang and Tsiatis type tests and considering the normal and exponential distributions to generate the data. This study confirms that for moderate coefficients of variation of the stopping rule, the bootstrap method allows adequate confidence intervals for the parameters to be obtained, whichever is the distribution of data.     

Proud to be poor? Untangling identity politics with the families portrayed in the photobook Courage (1998)

In the early 1990s, several European welfare states embraced the idea that the voice and life knowledge of people in poverty should be recognised in policymaking. In that regard, many authors proclaimed a paradigm shift from advocacy to self-advocacy, emphasising the agency of people in poverty to speak for themselves. Emblematic in these developments in Belgium was the photobook Courage, published in 1998 by an NGO called Movement for People with a Low Income and Children (BMLIK). Through documentary family photography and oral testimonies, Courage develops a visual rhetoric on the citizenship of people in poverty while reframing poverty as a violation of human rights. Historical research demonstrates, however, that Courage was produced by middle-class volunteer allies and is therefore a rhetorical tool for self-advocacy but certainly not a product of self-advocacy. Moreover, many authors have been highly critical of identity politics, since positive imagery can equally be disempowering in reinforcing neo-philanthropical principles of self-help and willpower which ultimately lead away from redistributive policies. This article therefore examines, through oral history with photo elicitation, how the people involved experienced being portrayed as the protagonists of self-advocacy on the poverty problem. The findings show how the portrayed people fluidly (dis)identified over the past 20 years through three intertwined subjective processes involving Courage as an artefact: for remembering (historical function), for assessing (evaluative function) and for advocacy (persuasive function). As such, they appear not as passive objects of others’ campaigning strategies, but as active co-constructors of self-advocacy rhetoric. Some of the pitfalls and potentials of identity politics in the struggle against poverty are discussed.     

Dealing with omitted answers in a survey on social integration of immigrants in Italy

ABSTRACT

Surveys are used to infer the level of social integration of immigrants. Item response theory helps to describe the relationship among responses to test items and latent traits of interest. However, in the presence of nonignorable missing data, which are omitted responses depending on the latent traits to be measured, estimates of the model parameters are biased. To account for nonignorable missing data, the quantity and quality of contacts between immigrants and natives (so called “social integration”) are taken into account through a linear function of the response propensity. Higher education, no intention to migrate again, young age, Albanian nationality, and declaring a non-Muslim religion or none, comparatively favor social integration.     

Assessment of physical workload in boiler operations

The use of boiler wood-fired is fairly common equipment utilized in steam generation for energy production in small industries. The boiler activities are considered dangerous and heavy, mainly due to risks of explosions and the lack of mechanization of the process. This study assessed the burden of physical labor that operators of boilers are subjected during the workday. Assessment of these conditions was carried out through quantitative and qualitative measurements. A heart rate monitor, a wet-bulb globe thermometer (WBGT), a tape-measure and a digital infrared camera were the instruments used to collect the quantitative data. The Nordic Questionnaire and the Painful Areas Diagram were used to relate the health problems of the boiler operator with activity. With study, was concluded that the boiler activity may cause pains in the body of intensity different, muscle fatigue and diseases due to excessive weight and the exposure to heat. The research contributed to improve the boiler operator's workplace and working conditions.     

Innovation and export performance: a study of Italian high-tech SMEs

The objective of the paper is to examine the influence of innovation measures on the export intensity of Italian high technology small and medium firms. In fact, despite a growing number of empirical studies attempting to guide the approximation of the value of innovation and its relative impact on the export intensity, a distinction between innovation input and output indicators, both internal and external to the firms has not been clearly established. Drawing on the innovation and export management literature, we used a sample of Italian firms operating in the high tech settings within the manufacturing industry (HTSMEs). Applying a 3?years lag time approach, we ran various Tobit regression models. Our empirical results revealed that: (1) R&D employees do positively and significantly impact the export intensity of HTSMEs, whereas R&D expenditures do not; (2) the use of ??Universities?? as external R&D partners has a positive influence on the export intensity of HTSMEs; (3) ??Product innovations?? and the ??Turnover derived from innovative activities?? positively and significantly affect the export intensity of firms in our sample.

Communicate over a network: the blog as a ‘new’ social space

The contribution analyzes from a sociological perspective the development of the blog, passing through the different typologies, to define the relationship that develops in today's society between the network and the individual, through a theoretical comparison of the major scholars who have dealt with the issue of network. From Sherry Turkle to Manuel Castells up to the studies of Barry Wellman, we will define the development of the network as a new social space. The work incorporates some classical theories of Simmel, some by Goffman and Thompson about interaction, of community-society by Töennies and the action-system of Luhmann. The central part of the article focuses on how the space of the network can become, in some cases, a ‘place’ of sharing not only of entertainment topics but also of those that have some importance for public opinion. Then the blog becomes a ‘showcase’ in which to expose the peculiar characteristics of one's identity, but also a point of listening for those who do not have easy access to traditional media. Through the testimony of two young people, we will highlight those aspects that characterize the blog as a communication tool, from the diary to the letter, as well as the role played by these documentary sources in the past in sociology's field. In this way, some salient points arise about the use of the network space, compared to traditional media. The last part of the contribution proposes a comparison between America and Japan about the use of blogs and social networks, no longer in numerical terms, but proposing a reflection that brings out an individual who, as a sociable being, exploits all the possible ways to communicate, feeling in such situations freer to express his emotions, and able build a dialogue that turns out to be an added value to his person and in relationship with others outside.     

Theorizing notions of the participation of people in poverty in social policymaking: Policing,politics and subjectification

Since the 1990s, a paradigm of participation has gained prominence and become a dominant policy rhetoric in anti-poverty policymaking in Europe, embracing the key idea that people in poverty should participate as equal citizens in political decision-making processes. Based on a historical case study of the production process of a Belgian white paper, the General Report on Poverty (1994), we investigate who participated in the GRP production process, and whether the underlying participatory and democratic mechanisms produced a shift in power and might have led to a more socially just and equal society. We rely on a central set of ideas of the French philosopher Jacques Rancière to theorize different notions of participation, and tease out whether the processing of equality had the capacity to move from policing towards politics through subjectification. Our research study demonstrates how social change and a reconfiguration of the democratic order can appear as a moment of democracy, yet inevitably leads to a new police.
