Consumers' need for uniqueness: short‐form scale development and cross‐cultural validation

Abstract: Purpose – The purpose of this paper is to develop and validate cross‐culturally a short‐form, consumers' need for uniqueness (CNFU) scale. The length of the original scale (31 items) might have hindered its diffusion in research when questionnaire length and respondent fatigue are major considerations.Design/methodology/approach – The paper uses survey‐based data from Israel, Slovenia, and the Palestinian Authority and uses a combination of statistical techniques, such as EFA, CFA, and structural equation modeling.Findings – In general, support was found for the cross‐cultural reliability and validity of the new, short‐form CNFU scale.Research limitations/implications – Future research can use the short‐form scale with additional confidence in its cross‐cultural reliability and validity.Practical implications – First, since CNFU appears not to be culturally bound, marketers can identify cross‐country segments of high‐CNFU individuals and use standardized marketing campaigns to reach them. Second, marketer...

D3S – A Discriminative Single Shot Segmentation Tracker

Abstract: Template-based discriminative trackers are currently the dominant tracking paradigm due to their robustness, but are restricted to bounding box tracking and a limited range of transformation models, which reduces their localization accuracy. We propose a discriminative single-shot segmentation tracker - D3S, which narrows the gap between visual object tracking and video object segmentation. A single-shot network applies two target models with complementary geometric properties, one invariant to a broad range of transformations, including non-rigid deformations, the other assuming a rigid object to simultaneously achieve high robustness and online target segmentation. Without per-dataset finetuning and trained only for segmentation as the primary output, D3S outperforms all trackers on VOT2016, VOT2018 and GOT-10k benchmarks and performs close to the state-of-the-art trackers on the TrackingNet. D3S outperforms the leading segmentation tracker SiamMask on video segmentation benchmark and performs on par with top video object segmentation algorithms, while running an order of magnitude faster, close to real-time.

Review: titanium and titanium alloy applications in medicine

Abstract: Titanium may be considered a relatively new engineering material. It was discovered much later than the other commonly used metals, its commercial application starting in the late 1940s. Its usage as an implant material began in the 1960s, despite the fact that titanium exhibits superior corrosion resistance and tissue acceptance when compared with stainless steels and Cr-Co-based alloys. This paper reviews the use of titanium and titanium alloys for use in biomedical applications.

“You Don't Understand, This is a New War!” Analysis of Hate Speech in News Web Sites' Comments

Abstract: Because news websites' comments have become an important space of spreading hate speech, this article tries to contribute to uncovering the characteristics of Internet hate speech by combining discourse analyses of comments on Slovenian news websites with online in-depth interviews with producers of hate speech comments, researching their values, beliefs, and motives for production. Producers of hate speech use different strategies, mostly rearticulating the meaning of news items. The producers either are organized or act on their own initiative. The main motive of soldiers and believers is the mission; they share characteristics of an authoritarian personality. The key motives of the players are thrill and fun. The watchdogs are motivated by drawing attention to social injustice. The last two groups share the characteristics of a libertarian personality.

Palatable leptoquark scenarios for lepton flavor violation in exclusive b → sℓ 1 ℓ 2 modes

Abstract: We examine various scenarios that involve a light $$ \mathcal{O} $$ (1 TeV) leptoquark state and select those which are compatible with the current experimental values for ℬ(B s → μμ), $$ \mathrm{\mathcal{B}}{\left(B\to K\mu \mu \right)}_{\mathrm{large}-{q}^2},{R}_K={\mathrm{\mathcal{B}}}^{\prime}\left(B\to K\mu \mu \right)/{\mathrm{\mathcal{B}}}^{\prime}\left(B\to Kee\right) $$ , and which lead to predictions consistent with other experimental data. We show that two such scenarios are phenomenologically plausible, namely the one with a doublet of scalar leptoquarks of hypercharge 1/6, and the one with a triplet of vector leptoquarks of hypercharge 2/3. We also argue that a model with a singlet scalar leptoquark of hypercharge 1/3 is not viable. Using the present experimental data as constraints, it is shown that the exclusive lepton flavor violating decays, ℬ(B s → μτ), ℬ(B → Kμτ) and ℬ(B → K ∗ μτ), can be as large as $$ \mathcal{O}\left(1{0}^{-5}\right) $$ .
