The recent trend of integrated risk management has resulted in corporations reassessing their risk management practices. Insurance derivatives and insurance‐linked securities are emerging as alternatives or complements to traditional resisurance capacity. Despite its theoretical benefits, the market for insurance‐linked transactions has not matured, due to problems of information asymmetry and lack of transparency. This article proposes a solution to resolve the conflicting interests preventing insurers/reinsurers and investors from more widely trading insurance risk.
Driving safety on a wet road is closely related to the wet skid resistance of tires. The purpose of this paper is to reveal the evolution of wet skid resistance at different water film thicknesses and provide some guidance on the design of a tread pattern with improved traction on rainy roads.
Brake tests are performed in a laboratory with a viscoelastic tribotester at various water film thicknesses. The initial water film thickness is 3 mm, which decreases with an increase in the test number. Brake friction force is dynamically measured at water film thicknesses ranging from 0 mm to 3 mm.
The results show that water film thickness exerts a great influence on the forms of tire motion and slip ratio. The tire is much easier to slide on the road with thick water film and also with a considerably thin water film (about 0-1 mm) during a sharp braking process. The brake traction can be very low under this road condition despite the apparently safe quality of the road.
The authors design and establish a new viscoelastic tribotester which is used to simulate the real braking sliding process and study the tribological properties between tire rubber and road surface. The variation in the wet friction coefficient and slip ratio at different water film thicknesses have a great influence on the design of a tread pattern with improved traction on rainy roads.

Pebble Technology Corporation (Pebble) was an early entrant into the smartwatch industry. Pebble’s Founder, Eric Migicovsky, began thinking about creating a smartwatch in 2008 while still an undergraduate engineering student. After selling about 1,500 prototype watches, he was accepted into Silicon Valley’s prestigious Y Combinator business start-up program. Finding it difficult to attract investors, Migicovsky launched a crowdfunding campaign that raised a record-breaking $10.27m on Kickstarter. The case concludes shortly after Apple’s unveiling of its soon-to-be-released Apple Watch. The case provides an opportunity to evaluate Pebble’s various strategic options at the time of Apple’s announcement.
The authors observed over 30 h of video and audio recordings of speeches, interviews and other events involving Pebble’s founder, other Pebble executives, investors and competitors. These recordings are all publicly available. Whenever possible, the authors also reviewed the Twitter feeds, Facebook sites and personal websites of Pebble’s top executives over time. Similarly, the authors followed Pebble’s official website, corporate blog and Kickstarter campaign websites. The authors also drew from numerous media reports. Due to the public nature of the data, no company release is provided nor has any information been disguised in any way.

The case is designed for both undergraduate and graduate students for courses in strategic management.

This paper sets out to design and realize a highly linear, wide dynamic range and high switching efficiency integrated CMOS up‐conversion mixer for two‐step IEEE 802.1a WLAN transmitter application in 0.18‐μm deep submicron CMOS technology.
A folded current draining low‐voltage mixer architecture is explored and an extensive simulation carried out utilizing Cadence Spectre‐RF tool in optimizing the linearity, input third‐order intercept point (IIP3), the dynamic range, 1 dB compression point (P−1dB), power dissipation and reduction of switching quad Cgs, input gate‐source capacitance, in enhancing the switching efficiency of the proposed architecture.
A highly linear, high input dynamic range, low voltage folded up‐conversion mixer architecture is realized in a significant comparable performance with respect to conventional reported architecture, indicating −8.87 dBm of OIP3 corresponding to 15.27 dBm IIP3 and 4.37 dBm of P−1dB in 0.18‐μm CMOS technology.
The optimized mixer architecture is stringent to an up‐converter application. To be utilized as a down converter at the receiver end, parameters, namely as noise figure and conversion gain, are of additional importance.
The designed folded mixer architecture is in need of integration to a two‐step up‐conversion transmitter architecture which relaxes the injection pulling effect for a given low voltage headroom, with low power dissipation design.
In this work, an integrated folded architecture with on‐chip process, voltage and temperature compensated biasing circuit is explored and enhanced, raising awareness of adapting improved multiplier blocks in achieving optimal performance in WLAN transceiver architecture.

Logistics capability is an important ability for transport and logistics firms to deliver the value and services to the customers. In contrast, supply chain uncertainty and risk is an issue in supply chain and logistics to obstruct the delivery. The purpose of this paper is to evaluate and understand the logistics capability, and to provide empirical evidence for logistics capability mitigating supply chain uncertainty and risk in the Australian courier firms.
This study examines the relationship between logistics capability and supply chain uncertainty and risk. Partial least squares approach for structural equation modelling is applied for data analysis involving the interplay of theoretical thinking and empirical data. Empirical data are collected through a web-based survey. Total 98 Australian courier firms are identified and invited in the study.
Based on the factor analysis, the authors identify the key factors of logistics capability for the Australian courier firms. This would help both academics and practitioners to have a better understanding of logistics capability in the transport ad logistics firms. In addition, results indicate that there is a negative relationship between logistics capability and supply chain uncertainty and risk in the Australian courier firms.
The result in support of logistics capability mitigating supply chain uncertainty and risk. It also makes a contribution to logistics risk management literature. The paper focuses on the Australian courier industry. Therefore, any generalisation to other countries or sectors must be made with caution.
This paper provides an insight into supply chain uncertainties and risks management. This would result in the development of a practical guidance for practitioners developing and deploying logistics capability to support and enable supply chain risk management strategies.
