Mathematical theory of voting and social choice has attracted much attention. In the general setting one can view social choice
as a method of aggregating individual, often conflicting preferences and making a choice that is the best compromise. How
preferences are expressed and what is the “best compromise” varies and heavily depends on a particular situation.
The method we propose in this paper depends on expressing individual preferences of voters and specifying properties of the
resulting ranking by means of first-order formulas. Then, as a technical tool, we use methods of second-order quantifier elimination
to analyze and compute results of voting. We show how to specify voting, how to compute resulting rankings and how to verify
voting protocols. 相似文献

This study investigates changes in latent mental structures along the anaclitic and introjective dimensions in relation to outcomes in 14 cases of publicly financed psychoanalysis. The method of prototype matching was adapted for personality assessment, and multiple outcome measures were applied. For the anaclitic cases, symptom reduction was accompanied by more mature integration of anaclitic and introjective personality dimensions, while the introjective cases showed symptom reduction without such improvement. This could indicate that sustainable change in latent mental structures is more difficult to achieve in introjective than in anaclitic patients. Further research is needed to validate these preliminary results. 相似文献

The technological advances of the 20th century resulted in the creation of the Internet and its introduction into everyday life on a global scale. The Internet provides access to information and the sale and purchase of goods. Medications are also subject to trade. Their sale is conducted by online pharmacies and their global turnover amounts to hundreds of billions of dollars. Medications ordered over the Internet are sent by mail all over the world. Considering the events of recent years, we cannot exclude the risk of a terrorist attack through online pharmacies. Terrorists can establish such companies, legally or illegally, or acquire ones already existing. Parcels, which are highly trusted by the customers of online pharmacies, can, for example, be contaminated with dangerous materials. The sale of online medications in the international system is potentially dangerous and requires international regulation. 相似文献

Despite the impact of the COVID-19 outbreak being largely negative on parents and children, for some families, lockdown could also bring about some positive effects, for example, increased emotional closeness, and more time for joint activity. The aim of the current study was to investigate cross-sectionally the most important correlates of the positive experiences in the parent–child relationship among Polish mothers and fathers during the lockdown in the initial phase of the COVID-19 outbreak. In May 2020, 228 mothers and 231 fathers completed the Brief version of the Empathic Sensitivity Questionnaire, Difficulties in Emotion Regulation Scale Short Form, Social Support Scale, Parenting Self-Agency Measure, and Scale of Positive Experiences in Parent–Child Relationship during the COVID-19 lockdown. Our results showed that parenting self-efficacy and social support were the strongest correlates of positive experiences in the parent–child relationship in both mothers and fathers during the lockdown. Perspective-taking was positively related to the positive experiences in mothers, whereas personal distress was positively associated with the positive experiences in the parent–child relationship in fathers. Our results point to factors of potential importance in designing preventive and therapeutic interventions for mothers and fathers to enhance positive experiences in the parent–child relationship during the pandemic. 相似文献
