How experimental algorithmics can benefit from Mayo’s extensions to Neyman–Pearson theory of testing
Thomas Bartz-Beielstein 《Synthese》2008,163(3):385-396
Although theoretical results for several algorithms in many application domains were presented during the last decades, not
all algorithms can be analyzed fully theoretically. Experimentation is necessary. The analysis of algorithms should follow
the same principles and standards of other empirical sciences. This article focuses on stochastic search algorithms, such
as evolutionary algorithms or particle swarm optimization. Stochastic search algorithms tackle hard real-world optimization
problems, e.g., problems from chemical engineering, airfoil optimization, or bio-informatics, where classical methods from
mathematical optimization fail. Nowadays statistical tools that are able to cope with problems like small sample sizes, non-normal
distributions, noisy results, etc. are developed for the analysis of algorithms. Although there are adequate tools to discuss
the statistical significance of experimental data, statistical significance is not scientifically meaningful per se. It is
necessary to bridge the gap between the statistical significance of an experimental result and its scientific meaning. We
will propose some ideas on how to accomplish this task based on Mayo’s learning model (NPT*). 相似文献

This paper studies long-term norms concerning actions. In Meyer’s Propositional Deontic Logic (PD
e
L), only immediate duties can be expressed, however, often one has duties of longer durations such as: “Never do that”, or
“Do this someday”. In this paper, we will investigate how to amend PD
e
L so that such long-term duties can be expressed. This leads to the interesting and suprising consequence that the long-term
prohibition and obligation are not interdefinable in our semantics, while there is a duality between these two notions. As
a consequence, we have provided a new analysis of the long-term obligation by introducing a new atomic proposition I (indebtedness) to represent the condition that an agent has some unfulfilled obligation.

Our study explores the clinical and non-clinical characteristics associated with medication use among children with serious
emotional disturbance who are referred into community-based family-driven system of care settings. Using data collected as
part of the Comprehensive Community Mental Health Services for Children and Their Families Program initiative, our study provides
results from analyses completed on 7,009 children and adolescents with serious emotional disturbance. Using both bivariate
and multivariate statistical analyses, the researchers found that females entering systems of care were less likely to have
received medication in the 6-months prior to entry, as were children of African-American and Native-American heritage compared
to children from non-Hispanic White heritage. Children referred from mental health, child welfare or who were self-referred
were more likely to use medications than those referred from juvenile justice. Children with histories of prior inpatient,
outpatient, day treatment, or school-based services were between 2 and 4 times more likely to use medications than children
without such histories. Children with family histories of mental illness and those who were Medicaid recipients were also
more likely to use medications. Family income was also positively related to medication use and younger children were more
likely to use medications than older children. Implications of the findings are discussed. 相似文献

Previous empirical research has been unable to find a sufficient correlation between subjective well-being and per capita income, being hampered by limited longitudinal information and an inability to account for the predictions of competing theories. We bring new evidence to this question by exploiting a long and complete time-series from the Eurobarometer Survey, 1973–2002 allowing an examination of trends in life satisfaction across 15 European countries employing a modified version of Kendall’s Tau. Our results show that while current GDP growth does not affect trends in well-being, accelerations in GDP growth do. In addition, faster GDP growth and faster growth of government consumption than in neighbouring countries induces positive trends in life satisfaction. Our findings are consistent with the predictions of aspirations theory and the theory of reference group comparisons. 相似文献

Decades of research have examined the structure of self-consciousness in adults and its relationship to social anxiety. This
study examined the structure of self-consciousness via the Self-Consciousness Scales (Fenigstein et al., J. Consult. Clin.
Psychol. 43:522–527, 1975) in a school sample of 175 children and young adolescents (92 girls; mean age = 11.5). Confirmatory
factor analysis best supported a five-factor solution (Internal State Awareness, Self-Reflectiveness, Appearance Consciousness,
Style Consciousness and Social Anxiety). Although some factor based subscales evidenced low internal consistencies, convergent
and discriminant correlations with self-report measures of social phobia, negative affect, and positive affect as well as
parent-report measures of internalizing and externalizing problems provided additional support for the five-factor model.
Future studies should further examine the multidimensional nature as well as the developmental course of self-consciousness
and its relation to social anxiety longitudinally.

This article considers the question of whether it is meaningful to speak of privacy rights in public spaces, and the possibility
of such rights framing the basis for regulating or restricting the use of surveillance technologies such as closed circuit
television (CCTV). In particular, it responds to a recent article by Jesper Ryberg that suggests that there is little difference
between being watched by private individuals and CCTV cameras, and instead argues that state surveillance is qualitatively
different from (and more problematic than) surveillance by ‘lonely old ladies’.

This article brings out certain philosophical difficulties in Lacan’s account of the mirror stage, the initial moment of the
subject’s development. For Lacan, the “original organization of the forms of the ego” is “precipitated” in an infant’s self-recognition
in a mirror image; this event is explicitly prior to any social interactions. A Hegelian objection to the Lacanian account
argues that social interaction and recognition of others by infants are necessary prerequisites for infants’ capacity to recognize
themselves in a mirror image. Thus mutual recognition with another, rather than self-recognition in a mirror, is what makes
possible subsequent ego-formation and self-consciousness. This intersubjective critique suggests that many of the psychoanalytic
consequences that Lacan derives from the mirror stage (e.g., alienation, narcissism, and aggressivity) may need to be rethought.

This paper examines three accounts of the sleeping beauty case: an account proposed by Adam Elga, an account proposed by David
Lewis, and a third account defended in this paper. It provides two reasons for preferring the third account. First, this account
does a good job of capturing the temporal continuity of our beliefs, while the accounts favored by Elga and Lewis do not.
Second, Elga’s and Lewis’ treatments of the sleeping beauty case lead to highly counterintuitive consequences. The proposed
account also leads to counterintuitive consequences, but they’re not as bad as those of Elga’s account, and no worse than
those of Lewis’ account.

This article investigates the types of intentionality involved in human–technology relations. It aims to augment Don Ihde’s
analysis of the relations between human beings and technological artifacts, by analyzing a number of concrete examples at
the limits of Ihde’s analysis. The article distinguishes and analyzes three types of “cyborg intentionality,” which all involve
specific blends of the human and the technological. Technologically mediated intentionality occurs when human intentionality takes place “through” technological artifacts; hybrid intentionality occurs when the technological actually merges with the human; and composite intentionality is the addition of human intentionality and the intentionality of technological artifacts.
