Union decline is one of the most important explanations for America's shortfall in upward mobility in recent decades. Union density—the fraction of workers who belong to labor unions, a common-use proxy for …
The efficiency depends heavily on which tree get attached to the other. There are 2 ways in which it can be done. First is Union by Rank, which considers height of the tree as the factor and Second is Union by Size, which considers size of the tree as the factor while attaching one tree to the other .
1. Introduction. Water is a vital resource for natural ecosystems and human life, and therefore, as stated by the European Union (EU) Water Framework Directive, a "heritage which must be protected, defended and treated as such" (European Union, 2000).Especially freshwater is limited in quantity and in quality, and currently under a variety of increasing …
Union members earn 10.2 percent more on average than nonunion workers who have comparable jobs and comparable experience. And that wage premium is even higher for women and workers of color. By raising wages and reducing income inequality, unions also spur the nation's economic growth. ... Myth: Unions Hurt Efficiency and Productivity.
Creation of the climate-smart agriculture requires efficient resource use and mitigation of the environmental pressures among other objectives. Therefore, it is important to assess the energy efficiency and productivity growth in the European Union's agriculture. This paper analyses the sample of the selected European Union member states.

The shipping industry is increasingly embracing wind propulsion technology to enhance ship efficiency and reduce the sector's CO2 emissions. Union Maritime's two new long-range tankers are the latest vessels to adopt BAR Technologies' WindWings® solution, following the successful installation of the technology onto the Pyxis Ocean and ...
The union algorithm calculates the union of two models based on their differences from a given original/base model, where two separate modifications are made to a base model, and the union algorithm combines both differences into one model by interleaving the operations from the latter difference with the former difference.
An object detector based on convolutional neural network (CNN) has been widely used in the field of computer vision because of its simplicity and efficiency. The average accuracy of CNN model detection results in the object detector is greatly affected by the loss function. The precision of the localization algorithm in the loss function is the main factor affecting the result. Based on the ...

UNEP leads the United for Efficiency (U4E) initiative, a public-private partnership that seeks to accelerate the worldwide transition to efficient commercial, industrial, and outdoor lighting, commercial and residential refrigerators, room air conditioners, electric motors, and distribution transformers. U4E brings together key stakeholders active in product efficiency to: Inform …
The over-threshold set-union is normally defined as follows: given a threshold t, ... In order to handle this defect, we present an efficient protocol in the honest-but-curious model by leveraging threshold secret sharing and dual pairing vector spaces. We prove that the proposed protocol not only has communication complexity which nearly ...

Understanding Credit Union Efficiency Ratio. In the credit union and the banking industry, the importance of numbers can't be overstated. Whether it's net new deposits, loan growth, member retention rate, or any other credit union …
2.2 Problem Definition. In the paper, we mainly investigate the over-threshold set-union problem. Informally speaking, this problem is as follows: the aggregator only learns the data items which appear at least t times in the union of private data items of all participants without obtaining extra knowledge about other data items. The formal definition states as follows.

Existing approaches that address worst-case performance under the union of such threat models (e.g., ℓ∞, ℓ 2, ℓ 1) either utilize adversarial training methods that require multi-step attacks which are computationally expensive in practice, or rely upon fine-tuning of pre-trained models that are robust with respect to a single-threat ...
Employers often fight unionizing efforts with aggression and intimidation, using legal and illegal tactics. Not all employers oppose unions. Some unions featured in this report were voluntarily recognized by employers, and some led campaigns in which the employer provided union organizers with free access to employees.73 But often, when private-sector …
The Union network is a hyper-efficient zero-knowledge infrastructure layer for general message passing, asset transfers, NFTs, and DeFi. It's based on consensus verification and has no dependencies on trusted third parties, oracles, multi-signatures, or MPC.. Union uses advanced Zero-Knowledge Cryptography and BLS signatures to bring the fastest and most secure inter …
UNION ALL is faster than UNION because plain UNION is expecting that in two joined datasets are duplicates which need to be removed. If you can ensure (by inner where clauses) that there will be no duplicates, it's far better to use UNION ALL …
