Abstract We study the effect of electromagnetic interactions on the classical soft theorems on an asymptotically AdS background in 4 spacetime dimensions, in the limit of a small cosmological constant or equivalently a large AdS radius l. This identifies 1/l2 perturbative corrections to the known asymptotically flat spacetime leading and subleading soft factors. Our analysis is only valid to leading order in 1/l2. The leading soft factor can be expected to be universal and holds beyond tree level. This allows us to derive a 1/l2 corrected Ward identity, following the known equivalence between large gauge Ward identities and soft theorems in asymptotically flat spacetimes.

Abstract We study two-to-two parton scattering amplitudes in the high-energy limit of perturbative QCD by iteratively solving the BFKL equation. This allows us to predict the imaginary part of the amplitude to leading-logarithmic order for arbitrary t-channel colour exchange. The corrections we compute correspond to ladder diagrams with any number of rungs formed between two Reggeized gluons. Our approach exploits a separation of the two-Reggeon wavefunction, performed directly in momentum space, between a soft region and a generic (hard) region. The former component of the wavefunction leads to infrared divergences in the amplitude and is therefore computed in dimensional regularization; the latter is computed directly in two transverse dimensions and is expressed in terms of single-valued harmonic polylogarithms of uniform weight. By combining the two we determine exactly both infrared-divergent and finite contributions to the two-to-two scattering amplitude order-by-order in perturbation theory. We study the result numerically to 13 loops and find that finite corrections to the amplitude have a finite radius of convergence which depends on the colour representation of the t-channel exchange.

Employers and employees on the productivity of older workers Employers and employees on the productivity of older workers The employers' perception of the productivity of younger and older workers is a major determinant of their HRM- and hiring policies with respect to both groups of workers. Using information from surveys among employers and employees we study employers' perceptions of younger and older workers, compare these perceptions with the perceptions held by employees and analyse the major determinants of these perceptions. Employers' perceptions appear to be determined primarily by factors like mental and physical capacity. Employees' overall perceptions depend more on 'soft' factors like loyalty, commitment and social skills.

Many studies on the implementation of quality management programs were carried out by previous researchers. However, the study on the soft or human factors in the implementation of quality management programs is still poorly explored. Therefore, this article aims to analyze soft factors in the implementation of quality management programs at Selangor Islamic Religious Council or Majlis Agama Islam Selangor (MAIS). This study uses a qualitative method involving MAIS as a case study. Semi-structured interviews were used as a data collection method and supported by relevant documents collected from MAIS. A total of fifteen informants comprising top management and MAIS officers were interviewed to obtain in-depth information on the subjects studied. The findings reveal that there are six soft factors emerged in the implementation of quality management programs at MAIS namely leadership, training and development, teamwork, customer focus, Syura and rewards. This study demonstrates that soft factors has helped facilitate the implementation of quality management programs in MAIS. The results of this study can be used as guidance by managers in public or corporate organizatons in their efforts to implement quality management programs effectively.
