Older workers and extended working life - Managers' experiences and age management.

Background: In 2020 the Swedish Government started a gradual raising of the retirement age, but employers have been silent on the issue. Little is known about whether and how they reflect on what it will mean for their organization, or whether they already have, or are going to, make arrangements in order to facilitate and motivate older workers to stay longer.

Objective: The aim of this study was to explore and describe managers' experiences of older workers and age management in connection with the increase of the retirement age in Sweden.

Breakdown of Temporal Coherence in Photon Condensates.

The temporal coherence of an ideal Bose gas increases as the system approaches the Bose-Einstein condensation threshold from below, with coherence time diverging at the critical point. However, counterexamples have been observed for condensates of photons formed in an externally pumped, dye-filled microcavity, wherein the coherence time decreases rapidly for increasing particle number above threshold. This Letter establishes intermode correlations as the central explanation for the experimentally observed dramatic decrease in the coherence time beyond critical pump power.

A Simple Model of the Rise and Fall of Civilizations.

The literature on the fall of civilizations spans from the archaeology of early state societies to the history of the 20th century. Explanations for the fall of civilizations abound, from general extrinsic causes (drought, warfare) to general intrinsic causes (intergroup competition, socioeconomic inequality, collapse of trade networks) and combinations of these, to case-specific explanations for the specific demise of early state societies. Here, we focus on ancient civilizations, which archaeologists typically define by a set of characteristics including hierarchical organization, standardization of specialized knowledge, occupation and technologies, and hierarchical exchange networks and settlements.

A randomized trial comparing percutaneous endoscopic gastrostomy (PEG) and radiologically inserted percutaneous gastrostomy (RIG).

Background And Objective: At present, percutaneous endoscopic gastrostomy (PEG) is the procedure of choice in establishing a permanent feeding tube in patients with chronic severe dysphagia. This is the first prospective randomized study in adults comparing PEG with radiologically inserted gastrostomy (RIG).

Methods: Randomization of 106 patients, eligible for both techniques, to PEG (pull method) or RIG.
