Optimal Pricing with Recommender Systems

We study optimal pricing in the presence of recommender systems. A recommender system affects the market in two ways: (i) it creates value by reducing product uncertainty for the customers and hence (ii) its recommendations can be offered as add-ons which generate informational externalities. The quality of the recommendation add-on is endogenously determined by sales. We investigate the impact of these factors on the optimal pricing by a seller with a recommender system against a competitive fringe without such a system. If the recommender system is sufficiently effective in reducing uncertainty, then the seller prices otherwise symmetric products differently to have some products experienced more aggressively. Moreover, the seller segments the market so that customers with more inflexible tastes pay higher prices to get better recommendations.Recommender system, Collaborative filtering, Add-ons, Pricing, Information externality

Efficient Recommender Systems

We study the efficient allocation of buyers in the presence of recommender systems. A recommender system affects the market in two ways: (i) it creates value by reducing product uncertainty for the customers and hence (ii) its recommendations can be offered as add-ons, which generates informational externalities. We investigate the impact of these factors on the efficient allocation of buyers across different products. We find that the efficient allocation requires that the seller with the recommender system has full market share. If the recommender system is sufficiently effective in reducing uncertainty, it is optimal to have some products to be purchased by a larger group of people than others. The large group consists of customers with flexible tastes.Recommender system, Collaborative filtering, Add-ons, Pricing, Information externality

Değerleme ölçülerinin Türkiye muhasebe/finansal raporlama standartları, bobi frs ve vuk açısından karşılaştırılması: Finansal durum tablosu aktif yapısı üzerine bir çalışma

In this study, the valuation principles and measures in the Tax Procedure Law (VUK), Turkey Full Set Accounting / Financial Reporting Standards (TMS/TFRS) and Financial Reporting Standards for Large and Medium Enterprises (BOBİ FRS) are examined. The aim of this study is; it is the comparison of the valuation principles and measures in terms of TMS/TFRS, BOBI FRS and VUK on the elements of the asset structure of the statement of financial position and to demonstrate a common valuation basis and measure. The focus of the study is the approaches adopted by VUK, TMS/TFRS and BOBI FRS in terms of financial reporting. While the VUK focuses on the realization of financial reporting in terms of accurate calculation of the tax to be provided by the enterprises to the state, TMS/TFRS and BOBI FRS aim to provide financial information that is appropriate and truthful, understandable, comparable, verifiable and timely to those who need financial information. Valuation measures also differ due to the difference in the goals adopted

Pengembangan Media Panama pada Materi Bangun Datar di Kelas VII SMP Katolik Marsudi Siwi Malang

Learning using computer media can stimulate students to do exercises, carry out learning activities because of the availability of animated cartoons, colors, and music. The results of observations at Marsudi Siwi Catholic Middle School Malang show that the use of mathematics learning media is very minimal. This is one of the reasons why students have difficulty understanding mathematics and are less interested in mathematics. The objectives of this study are: (1) to describe the development of panama media using the Macromedia Flash application on the Bangun Datar material and (2) to describe the validity, practicality, and effectiveness of panama media using Macromedia flash. The method used in this research is the Four-D device development method which consists of 4 stages, namely: (1) define; (2) design or design; (3) develop or develop; and (4) disseminate or spread. The development stage is only limited to the develop stage. Data collection techniques used expert assessment questionnaires, student response questionnaires, and test questions for students' conceptual understanding. The data analysis technique used is quantitative and qualitative data analysis. The subjects of this study were students of class VII A of Marsudi Siwi Catholic Middle School Malang. Based on the research results, Panama media uses Macromedia flash which meets the criteria of validity, practicality, and effectiveness. The validity of the media was indicated by the results of the material expert's assessment with an average value of 3.57 (valid criteria and without revision), while the media expert's assessment obtained an average value of 3.63 (valid criteria and without revision). The practicality of the media is indicated by the assessment of the student response questionnaire in the small group test with an average value of 3.51 (very practical criteria), while in the large group test an average value of 3.48 (very practical criteria) is obtained. The effectiveness of the media is indicated by the results of the conceptual understanding test with an average value of 75.83 (good category)

Stringent upper limit on the direct 3α decay of the Hoyle state in 12C

We investigate an implication of the most recent observation of a second Jπ=2+ state in 12C, which was measured using the 12C(γ,α)8Be(g.s.) reaction. In addition to the dissociation of 12C to an α-particle and 8Be in its ground state, a small fraction of events (2%) were identified as direct decays and decays to excited states in 8Be. This allowed a limit on the direct 3α partial decay width to be determined as Γ3α<32(4) keV. Since this 2+ state is predicted by all theoretical models to be a collective excitation of the Hoyle state, the 3α partial width of the Hoyle state is calculable from the ratio of 3α decay penetrabilities of the Hoyle and 2+ states. This was calculated by using the semiclassical Wenzel-Kramers-Brillouin approach and we deduce a stringent upper limit for the direct decay branching ratio of the Hoyle state of Γ3α Γ <5.7×10−6, over an order of magnitude lower than previously reported. This result places the direct measurement of this rare decay mode beyond current experimental capabilities
