Abstract

Purpose

To explain the final position limit aggregation rules and exemptions pertaining to derivative positions in nine agricultural commodities adopted by the Commodity Futures Trading Commission on December 5, 2016 and effective February 14, 2017, the notice filing deadline with respect to which was extended by the CFTC by limited time no-action relief until August 14, 2017.

Design/methodology/approach

Explains the position limit aggregation rules and exemptions pertaining to equity interests in owned entities, ownership or equity interests in pooled accounts or positions, positions of an “eligible entity” in connection with client positions carried by an “independent account controller,” positions held by futures commission merchants (FCMs) in discretionary accounts or customer trading program accounts, equity interests of underwriters based on unsold allotments of securities in distributions, broker-dealers if the equity interest is acquired in the normal course of business and positions for which information cannot be collected without risk of violating a law.

Findings

Unless an exemption from aggregation is available, all positions in accounts for which any person controls the trading or holds a 10 per cent or greater ownership or equity interest must be aggregated with positions held, and trading done, by such person. The final rule adds several new exemptions, including for persons with a 10 per cent or greater ownership or equity interest in an entity so long as certain conditions establishing independence are met. The final rule requires notice filing to take advantage of most exemptions from aggregation.

Originality/value

Practical guidance from experienced lawyers specializing in securities, funds, and investment management.

Abstract

CELLULOSE is Nature's strong material. It is the chief constituent of cotton flax and wood. Wood can be turned into sugars by treatment with hydrochloric acid Bergius process) and by certain termites; horses and cows break down the cellulose in grass into sugar before digesting it. So it is not surprising that the cellulose polymer is built up of what are practically molecules of a glucose (“Barley Sugar”). Each β glucose unit is twisted about its axis through 180 deg.; the combination of two such units makes up that is called a cellulose unit which has the structure shown in Fig. 2. The cellulose polymer is a long, straight chain made up from these cellobiose units, and each chain probably contains about 70 such units.

Abstract

THE marked dependence of the strength of metals on temperature, and on rate of loading at high temperatures, can be explained by assuming that above the equi‐cohesive temperature rupture takes place by plastic flow in a non‐homogeneous medium, consisting of rigid crystallites weakly cemented together. Although the stress concentrations required by the Griffith theory must still be operative above the equi‐cohesive temperature, it is suggested that they produce intergranular flow, rather than the elastic separation that occurs at temperatures below the equi‐cohesive temperature. A theory is developed based on the assumption that the strain energy at rupture reduces the energy of activation of the flow process, and the theory is shown to be in numerical agreement with the experimental results, if the energy of activation of the flow process is about one seventh of the latent heat of evaporation per gram atom. Values of the cohesive strengths and of the stress concentration factors are also derived.

Abstract

SYNTHETIC resins reinforced with fahric have proved in actual service to be not only resistant to disintegration from shocks and vibration but also to have remarkable freedom from “notch sensitivity.” In order to investigate this property measurements were made of the energy absorbed by such materials under torsional oscillation; it was found that the energy absorbed was greater than that of any other comparable materials (such as wood or metal).

Abstract

WOOD though in many ways an attractive structural material has the disadvantage of being water absorbent. In itself this characteristic would be of minor significance were it not for the fact that it is accompanied by considerable swelling at right angles to the axes of the wood fibres. Great interest is being shown at the present time in the possibility of reducing this swelling by the use of synthetic resins. In this article the possibility of preventing swelling by such means is discussed and it is concluded that complete immunity from swelling could only be attained at the expense of the strength of the wood. The article gives an original analysis which enables the magnitude of swelling to be predicted and the expression derived is shown to be in agreement with experiment.

Abstract

Purpose

Today's sharing economy covers a variety of business models. This research aims to (1) identify dimensions along which sharing businesses may vary and (2) investigate how these dimensions influence consumer engagement while considering consumers' sustainability orientation.

Design/methodology/approach

This research relies upon a systematic literature review (n = 67 articles) to identify five sharing business dimensions: (1) ownership transfer, (2) professional involvement, (3) compensation, (4) digitalization and (5) community scope. A discrete choice conjoint experiment in the fashion industry is employed to investigate how these dimensions affect consumer engagement with sharing businesses (n = 383 participants).

Findings

The results suggest that ownership of tangible resources elicits more engagement than access to tangible resources for both consumers with a low sustainability orientation and consumers with a high sustainability orientation. Community scope also affects consumer engagement as reflected in more engagement towards sharing businesses with a local rather than a global scope. The presence of professional service providers, monetary compensation and a digital platform only induces engagement among consumers with a low sustainability orientation.

Originality/value

This research generates a better understanding of how sharing businesses can draw on business dimensions to engage consumers with different levels of sustainability orientation and, in turn, how sharing businesses can realize their economic and/or circular potential.

Abstract

WITHIN the last year or so we have learned to glue metals together with a strength which brings this method of joining materials into competition with riveting, at least in the thin gauges used in the aircraft and motor industries. Apart from this new extension of gluing to the metal working trades synthetic adhesives have already revolutionized the woodworking industries. This revolution is due to the superior quality of the resulting products and the increased rate of output made possible by the intrinsic high speed of setting of synthetic adhesives aided by such novel methods as high frequency heating, infra‐red heating and the like. In aircraft in particular the “weather‐resistance” of synthetic adhesives has largely removed the disadvantages of wood construction, due to the use of casein glues, so much in evidence in the first winter of this war. It may be said therefore that gluing has been raised from the status of a useful but humble convenience of daily life to a process of engineering significance. But before engineers can use gluing in the fabrication of structures they must be provided with data sufficient to enable thorn to compute the strength of the joints, and we at Aero Research Ltd. have therefore endeavoured to find a simple relation between the strength of a lap joint and its geometry. Such a simple relation is found in “the joint factor” which is defined3 as the square root of the thickness of the sheet divided by the length of the overlap.

Abstract

SYNTHETIC AND OTHER PLASTICS CELLULOSE and rubber are made of long chain molecules already built up for us by nature, but in recent years we have learned to make synthetic polymers with physical characteristics not unlike those of natural polymers; the variety of such synthetic polymers is already somewhat bewildering, and it is quite certain that chemists have only made a beginning in an exploration that promises to be as successful as anything achieved by the classical organic chemists of the nine‐teenth century. Like many other branches of knowledge the subject is easier to understand if not treated in the chronological order in which the discoveries have been made. We will therefore begin with a description of the vinyl polymers rather than the older and better‐known condensation resins.
