The Need for a Different Approach to Financial Reporting and Standard-setting

International Financial Reporting Standards are questioned. Possibly, there is a need for a different kind of standards and a different procedure for developing them. No doubt, there is a need for a more profound theoretical approach to these issues. Theory-building in accounting should include approaches whereby problem descriptions have a broad coverage and cross the boarders of traditional specialisations. In this paper, a theoretical approach is outlined. According to this approach, insights into control problems for every organisation and system can be gained by analysing relationships between global value chains and a hierarchy of one or several organisations. Time is crucial. Instrumentality is regarded as an inevitable and necessary guide line for any control system that relates resources to functions and visions. Instrumentality concerns the effects of tools on certain functions. In the paper financial reporting and standard-setting are placed in a wide context in which longitudinal relationships are essential for individuals, organisations and control systems. Basic financial accounting concepts and their relationships with business events are discussed. The importance of uncertainty for financial reporting is emphasized, and so is the fact, that control from top-levels is exercised at a distance. A tendency to instrumentalism is also recognized: measures and procedures, for example standard setting procedures, tend to be important in themselves, irrespective of ultimate economic functions in a wider perspective. The analysis in the paper is one application of a general approach to financial control for all types of organisations. The general approach is based on a number of previous research-oriented books published over several decades and the author´s specific own experiences from internal and external processes with organisations in focus. Consistency and integrative power of the ideas have been tested in relation to certain books in various fields outside the core of the subject: applied systems theory, theatre, sociology, economic history, institutional theory and economics.financial reporting; International Financial Reporting Standards; standard-setting; accounting standard setting bodies; supervisory boards; corporate governance; transparency; market value accounting; mark-to-market; fair values; historical values; accounting theory.

Towards a General Theory of Financial Control for Organisations

In this paper, a theory of accounting, control and accounting-related areas is outlined.It is based on a number of previous research-oriented books published over several decades and the author´s specific own experiences from internal and external processes with organisations in focus.Consistency and integrative power of the ideas have been tested in relation to certain books in various fields outside the core of the subject:theatre,sociology, applied systems theory,economic history, institutional theory and economics.The general approach can be described in simple terms as follows.There are global value chains, from resources to output that are in use.These chains change with time.Uncertainty and unpredictability prevail for the present state and for possible changes; to some extent it is possible to estimate risks of the future. At any moment, each organisation has taken some limited position on a chain.Each organisation has a hierarchy which lies above operations. Over time, chains, organisations, hierarchies, output and personal functions vary. According to the approach, insights into control problems for every organisation and system can be gained by analysing relationships between global value chains and a hierarchy of one or several organisations.Time is crucial.financial control; management control; public administration; financial entities; financial reporting; dependencies; function-driven organisations; pay-driven organisations; transfer-driven organisations; supervisory boards; mass media; auditors; natural systems; panarchy; pseudo-commercial units; inter-organisational control; long-term control; short-term effects; hierarchies; global value chains; vertical control; horizontal control; corporate governance; remote control; controllability; transparency; values-in-use; values-in-exchange; fair values; historical costing; opportunity costs; product costing; transfer pricing; local optimization; time-bound optimization; longitudinal relationships.

Finite-Blocklength Bounds on the Maximum Coding Rate of Rician Fading Channels with Applications to Pilot-Assisted Transmission

We present nonasymptotic bounds on the maximum coding rate achievable over a Rician block-fading channel for a fixed packet size and a fixed packet error probability. Our bounds, which apply to the scenario where no a priori channel state information is available at the receiver, allow one to quantify the tradeoff between the rate gains resulting from the exploitation of time-frequency diversity and the rate loss resulting from fast channel variations and pilot-symbol overhead

Peak-Age Violation Guarantees for the Transmission of Short Packets over Fading Channels

We investigate the probability that the peak age of information in a point-to-point communication system operating over a multiantenna wireless fading channel exceeds a predetermined value. The packets are scheduled according to a last-come first-serve policy with preemption in service, and are transmitted over the channel using a simple automatic repetition request protocol. We consider quadrature phase shift keying modulation, pilot-assisted transmission, maximum-likelihood channel estimation, and mismatched scaled nearest-neighbor decoding. Our analysis, which exploits nonasymptotic tools in information theory, allows one to determine, for a given information packet size, the physical layer parameters such as the SNR, the number of transmit and receive antennas, the amount of frequency diversity to exploit, and the number of pilot symbols, to ensure that the system operates below a target peak-age violation probability.Comment: 6 pages, 6 figures.

Diversity versus Multiplexing at Finite Blocklength

A finite blocklenth analysis of the diversity-multiplexing tradeoff is presented, based on nonasymptotic bounds on the maximum channel coding rate of multiple-antenna block-memoryless Rayleigh-fading channels.The bounds in this paper allow one to numerically assess for which packet size, number of antennas, and degree of channel selectivity, diversity-exploiting schemes are close to optimal, and when instead the available spatial degrees of freedom should be used to provide spatial multiplexing. This finite blocklength view on the diversity-multiplexing tradeoff provides insights on the design of delay-sensitive ultra-reliable communication links.Comment: Proc. IEEE Int. Symp. Wirel. Comm.

Low-Latency Short-Packet Transmissions: Fixed Length or HARQ?

We study short-packet communications, subject to latency and reliability constraints, under the premises of limited frequency diversity and no time diversity. The question addressed is whether, and when, hybrid automatic repeat request (HARQ) outperforms fixed-blocklength schemes with no feedback (FBL-NF) in such a setting. We derive an achievability bound for HARQ, under the assumption of a limited number of transmissions. The bound relies on pilot-assisted transmission to estimate the fading channel and scaled nearest-neighbor decoding at the receiver. We compare our achievability bound for HARQ to stateof-the-art achievability bounds for FBL-NF communications and show that for a given latency, reliability, number of information bits, and number of diversity branches, HARQ may significantly outperform FBL-NF. For example, for an average latency of 1 ms, a target error probability of 10^-3, 30 information bits, and 3 diversity branches, the gain in energy per bit is about 4 dB.Comment: 6 pages, 5 figures, accepted to GLOBECOM 201

Low-Complexity Joint Channel Estimation and List Decoding of Short Codes

A pilot-assisted transmission (PAT) scheme is proposed for short blocklengths, where the pilots are used only to derive an initial channel estimate for the list construction step. The final decision of the message is obtained by applying a non-coherent decoding metric to the codewords composing the list. This allows one to use very few pilots, thus reducing the channel estimation overhead. The method is applied to an ordered statistics decoder for communication over a Rayleigh block-fading channel. Gains of up to $1.2$ dB as compared to traditional PAT schemes are demonstrated for short codes with QPSK signaling. The approach can be generalized to other list decoders, e.g., to list decoding of polar codes.Comment: Accepted at the 12th International ITG Conference on Systems, Communications and Coding (SCC 2019), Rostock, German

Esotericism made exoteric? Insider and outsider perspectives on the 2006 Mormon Temple Public Open House in Espoo, Finland

The purpose of this article is to discuss two perspectives on Latter-day Saints’ (Mormons') temple open houses. First, that of the Latter-day Saints themselves, who are placed in a delicate situation as they present the temple to the public while simultaneously desiring to preserve its esoteric nature. What do they want to accomplish and how do they go about doing it? Second, the perspective of the public, whose reactions exemplify layman views of what it can be like to peek into a sacred and esoteric world foreign to oneself. What kinds of forms can their thoughts take at Mormon temple open houses? The particular case considered in this article is the autumn 2006 open house at the Helsinki Finland temple
