Why is financial stability a goal of public policy?

A number of developments in recent years have combined to put the issue of financial stability at the top of the agenda, not just of supervisory authorities, but of public policymakers more generally. These developments include: the explosive growth in the volume of financial transactions, the increased complexity of new instruments, costly crises in national financial systems, and several high-profile mishaps at individual institutions.> Policymakers care about financial instability because of the close linkages between financial stability and the health of the real economy. Recent examples of these linkages include the banking crises in Scandinavia and Japan, the 1995 peso crisis in Mexico, and the current exchange rate and banking problems in the emerging market economies of Southeast Asia.> In remarks made before the Federal Reserve Bank of Kansas City’s 1997 symposium, “Maintaining Financial Stability in a Global Economy,” Mr. Crockett examines the role of public policy in maintaining financial stability. In particular, he addresses the following questions: What do we mean by financial stability? Why should official intervention (as opposed to reliance on market forces) be required to promote stability? And what concrete approaches can be employed?Public policy ; Financial institutions

Efficient TV white space filter bank transceiver

Future devices operating in the TV white space (TVWS) spectrum will require to access different bands at different locations and times in order to avoid interference to incumbent users, requiring agility and sufficient spectral masks to satisfy regulators. Further, with very high-speed ADCs and DACs becoming reality, the purpose of this paper is to present a transceiver front-end capable of simultaneously up- and downconverting a significant portion of the UHF band. The proposed approach takes a two-stage filter-bank conversion for implementation on state-of-the-art FPGAs. We present three different parameterisations, which are compatible with the 40 TVWS channels between 470 and 790MHz in Europe, and compare them in terms of complexity and latency

Design considerations for a filter bank based TVWS transceiver

This paper discusses the design of a filter bank based transceiver capable of simultaneously up- or downconverting the entire TV white space (TVWS) frequency band. The spectral mask requirements favour a filter bank based approach, whereby RF sampling and the use of an FPGA for digital up- and down-conversion dictates a two-stage approach. Some of the design considerations, including filter design approaches, are discussed in this contribution

Digital RF multiplexing for a TVWS transceiver implementation

Future devices operating in the TV white space (TVWS) spectrum will require to access different bands at different locations and times in order to avoid interference to incumbent users, requiring agility and sufficient spectral masks to satisfy regulators. In order to realise radio devices capable of this, we briefly review design efforts on a radio transceiver capable up- and downconverting the 40 8MHz TVWS channels residing between 470MHz and 790MHz. While we briefly address the overall proposed structure, the aim of this contribution is to address the practical issues of interfacing data conversion devices sampling at RF to state-of-the-art FPGAs which can then perform the digital operations required for up- and downconversion

TVWS filter bank transceiver on OMAP-L137 evaluation module

Communications devices operating in the TV white space (TVWS) spectrum will be strictly regulated, requiring compliance with spectral masks to protect incumbent users and sufficient frequency agility to allow access to numerous frequency bands at different times and locations. Therefore, future designs operating at radio frequency (RF) have been proposed. The purpose of this paper is to demonstrate an implementation of such a transceivers at a scale-down frequency implemented on the OMAP--L137 evaluation module, whereby the RF link can be replaced by the device's audio I/O, thus enabling easier observation and algorithm testing for students

Partially reconfigurable TVWS transceiver for use in UK and US markets

With more and more countries opening up sections of unlicensed spectrum for use by TV White Space (TVWS) devices, the prospect of building a device capable of operating in more than one world region is appealing. The difficulty is that the locations of TVWS bands within the radio spectrum are not globally harmonised. With this problem in mind, the purpose of this paper is to present a TVWS transceiver design which is capable of being reconfigured to operate in both the UK and US spectrum. We present three different configurations: one covering the UK TVWS spectrum and the remaining two covering the various locations of the US TVWS bands

A qualitative exploration of the emotional wellbeing and support needs of new mothers from Afghanistan living in Melbourne, Australia

Background: The Afghan community is a priority population for many health and social services within the southeast region of Melbourne, which is home to the largest population of Afghanistan-born people within the state of Victoria. The majority of Afghan women arriving in Australia are of childbearing age, and evidence suggests that they are at increased risk of emotional challenges following birth as a result of the refugee and migration experience. This research aimed to explored the experiences of Afghan women living in Melbourne throughout pregnancy, birth, and early motherhood, and gain insight into the aspects of their experiences that they perceive as positively and negatively impacting their emotional wellbeing. Methods: This qualitative study collected data through two focus group discussions (conducted in Dari) and 10 in-depth interviews (conducted in Dari or English). Thirty-eight Afghanistan-born women aged 18 years and older, who recently migrated to Australia and have at least one Australian-born child, were purposively selected to participate. A trained bicultural worker assisted in recruitment, data collection and translation. Thematic analysis was performed, and findings were confirmed with a subgroup of participants prior to being included within reporting. Results: Participants consistently discussed experiencing emotional challenges following birth, identifying symptoms commonly associated with postnatal depression. Women largely attributed this emotional state to separation from family and culture, leading to loneliness, isolation, and disconnection. Participants expressed resistance towards professional support due to cultural stigma associated with mental illness. Partner support was seen to be positive but difficult to negotiate. Religion, strong relationship with child, forming friendships, education, and utilising childcare were identified as positive influences on the emotional wellbeing of women. Conclusions: This study highlighted social and cultural factors contributing towards the emotional wellbeing of Afghan mothers. Findings confirm the need for innovative community-based models to support the mental health of Afghan women. This is particularly pertinent given the identified resistance towards discussing emotional wellbeing with healthcare professionals. Further research and investment is required in this area
