Defining the Contours of ERISA Preemption of State Insurance Regulation: Making Employee Benefit Plan Regulation an Exclusively Federal Concern

Congress enacted the Employee Retirement Income Security Act (ERISA) in 19741 to address problems in the area of employee pensions and benefits, with which prior federal enactments and complementary state regulation had been unable to cope. ERISA established a comprehensive scheme that placed the regulation of qualified employee benefit plans exclusively in federal hands.\u27 The drafters of ERISA also sought to reserve to the states the power to regulate areas in which they traditionally had primacy--most notably, insurance, banking, and securities. The drafters of ERISA thus attempted to carve out an area of exclusive federal concern, while preserving state regulation of tangential areas, so as not to create a regulatory void, nor to infringe onstate police powers

Genetic algorithm based method of elimination of residual oscillation in mechatronic systems

summary:The paper presents control signals generation methods, preventing the excitation of residual vibration in slightly damped oscillational systems. It is focused on the feedforward methods, as most of the vibrations in examined processes are induced by the control, while the influence of disturbances is mostly negligible. Application of these methods involves ensuring of the insensitivity to natural frequency change, which can be reached in classical approach only by considerable increase of transient response duration. Genetic algorithms can be effectively applied for the numerical optimization of developed shaper while maintaining the insensitivity to parameter change and short time delay

Genderová schematizace v popisu vlastní osoby

Diplomová práca kriticky analyzuje vybrané miery maskulinity a feminity. Zvláštna pozornosť je venovaná predovšetkým inventáru BSRI (Bem Sex-Role Inventory), ktorý je dlhodobo najrozšírenejším, avšak úplne nevalidným nástrojom pre meranie gendrovej identity. Zároveň je predložený návrh alternatívneho prístupu k problematike gendrovej identity založený na aplikácii štatistickej techniky diskriminačnej analýzy na obecne zdieľane stereotypické hodnotenia mužov a žien. V empirickej časti je v praxi úspešne overené vytvorenie indexu maskulinity/feminity podľa tohto návrhu. Výsledky analýz vzťahov medzi takto stanovenou gendrovou identitou a rôznymi inými zložkami systému gendrových presvedčení (kognitívnou gendrovou schematizáciou, explicitnou mierou M/F a gendrovými postojmi) naznačujú validitu takéhoto prístupu. Medzi feminitou (bez ohľadu na pohlavie) a mierou tradičnosti gendrových postojov bol zistený neveľký, ale významný negatívny vzťah (rs = -0,3). Kľúčové slová: maskulinita, feminita, diskriminačná analýza, kritika BSRIThis thesis critically analyzes some measures of masculinity and femininity. Special attention is paid primarily to a BSRI (Bem Sex-Role Inventory), which is the most widespread but completely invalid instrument for measuring gender identity. At the same time, there is presented an alternative approach to the topic of gender identity based on an application of statistical discriminant analysis technique to generally shared stereotypical evaluations of typical men and women. In empirical part, proposed approach is successfully tested in practice by creating an index of masculinity / femininity. Results of analyzes of relations between the determined gender identity and various other components of gender belief system (cognitive gender schematization, an explicit M / F and gender attitudes) suggest the validity of this approach. Between feminity (regardless of sex) and a measure of traditional gender attitudes has been found small but significant negative correlation (rs = -0.3).

Taking Algorithmic (Vs. Human) Advice Reveals Different Goals to Others

People are increasingly likely to obtain advice from algorithms. But what does taking advice from an algorithm (as opposed to a human) reveal to others about the advice seekers’ goals? In five studies (total N = 1927), we find that observers attribute the primary goal that an algorithm is designed to pursue in a situation to advice seekers. As a result, when explaining advice seekers’ subsequent behaviors and decisions, primarily this goal is taken into account, leaving less room for other possible motives that could account for people’s actions. Such secondary goals are, however, more readily taken into account when (the same) advice comes from human advisors, leading to different judgments about advice seekers’ motives. Specifically, advice seekers’ goals were perceived differently in terms of fairness, profit-seeking, and prosociality depending on whether the obtained advice came from an algorithm or another human. We find that these differences are in part guided by the different expectations people have of the type of information that algorithmic- vs. human advisors take into account when making their recommendations. The presented work has implications for (algorithmic) fairness perceptions and human-computer interaction.</p

Predictors of Bribe-Taking: The Role of Bribe Size and Personality

Laboratory studies allow studying the predictors of bribe-taking in a controlled setting. However, presently used laboratory tasks often lack any connection to norm violation or invite participants to role-play. A new experimental task for studying the decision to take a bribe was designed in this study to overcome these problems by embedding the opportunity for bribe-taking in an unrelated task that participants perform. Using this new experimental task, we found that refraining from harming a third party by taking a bribe was associated with lower offered bribes and higher scores of the participants on the honesty-humility scale from the HEXACO personality inventory. A trial-level analysis showed that response times were longer for trials with bribes and even longer for trials in which bribes were accepted. These results suggest that taking a bribe may require overcoming automatic honest response and support the validity of the honesty-humility scale in predicting moral behavior

Deciding what to replicate:A decision model for replication study selection under resource and knowledge constraints

Robust scientific knowledge is contingent upon replication of original findings. However,researchers who conduct replication studies face a dicult problem; there are many morestudies in need of replication than there are funds available for replicating. To select studies forreplication eciently, we need to understand which studies arethe mostin need of replication.In other words, we need to understand which replication eorts have the highest expected utility.In this article we propose a general rule for study selection in replication research based onthereplication valueof the claims considered for replication. Thereplication valueof a claimis defined as the maximum expected utility we could gain by conducting a replication of theclaim, and is a function of (1) the value of being certain about the claim, and (2) uncertaintyabout the claim based on current evidence. We formalize this definition in terms of a causaldecision model, utilizing concepts from decision theory and causal graph modeling. We discussthe validity of usingreplication valueas a measure of expected utility gain, and we suggestapproaches for deriving quantitative estimates ofreplication value

A field experiment on dishonesty: A registered replication of Azar et al. (2013)

This study is a registered replication of a field experiment on dishonesty by Azar et al. (2013). Their main finding was that most customers of an Israeli restaurant did not return excessive change; however, customers who received a higher amount of excessive change returned it more often than people who received a lower amount. Our study, which was conducted on a sample of customers of restaurants in the Czech Republic (N=219), replicated the results of the original study. The high excessive change condition increased the chance of returning the excess change by 21.7 percentage points (17.4 percentage points in the original study). The findings show that the psychological costs of dishonesty can outweigh its financial benefits. We similarly found that repeat customers and women were more likely to return the excessive change than one-time customers and men. The majority (70%) of customers in our sample returned the excessive change. We discuss the importance of field studies and replications of them in the further development of research into dishonest behavior.This study is a registered replication of a field experiment on dishonesty by Azar et al.

The Process of Replication Target Selection in Psychology: What to Consider?

Increased execution of replication studies contributes to the effort to restore credibility of empirical research. However, a second generation of problems arises: the number of potential replication targets is at a serious mismatch with available resources. Given limited resources, replication target selection should be well justified, systematic, and transparently communicated. At present the discussion on what to consider when selecting a replication target is limited to theoretical discussion, self-reported justifications, and a few formalized suggestions. In this Registered Report, we proposed a study involving the scientific community to create a list of considerations for consultation when selecting a replication target in psychology. We employed a modified Delphi approach. First, we constructed a preliminary list of considerations. Second, we surveyed psychologists who previously selected a replication target with regards to their considerations. Third, we incorporated the results into the preliminary list of considerations and sent the updated list to a group of individuals knowledgeable about concerns regarding replication target selection. Over the course of several rounds, we established consensus regarding what to consider when selecting a replication target
