Abstract
In the summer of 1948 the Royal Society held a Scientific Information Conference which issued a lengthy report. This was discussed about a year later in a lecture by Professor Egerton to the Royal Society of Arts. His opening remarks were intended to startle the audience and were roughly along the following lines. The present rate of publication of scientific papers is approximately one million per annum, a number which is increasing. By far the biggest proportion of these, possibly up to 90 per cent., have little value other than to publicize the fact of their author's existence, since there is far too common a habit of rushing into print before experience has mellowed what might be an arbitrary or immature opinion. It is probable that not even 1 per cent. will have any value or be studied, say, ten years from their date of publication, and the effect of this welter of paper is that those who have to file or classify the information, and who are not in a position to decide the value of each paper, are, to a great extent, wasting their time.

Abstract
Purpose
The sports industry is a forerunner in the international quest for talent as the search by sport clubs and the corresponding self-initiated expatriation of athletes starts at a very early age. The purpose of this paper is to address this phenomenon by exploring the experiences of talented young Icelandic footballers (soccer players) in their transition from Iceland into senior-level professional football in European leagues across six dimensions – three individual and three cultural.
Design/methodology/approach
Biographical narrative interviews have been conducted with eight Icelandic players moving overseas at a young age with the purpose of advancing their career. To investigate the coping strategies applied, a purposeful sampling approach was chosen, given that half of the participants successfully dealt with transitions in their career, while the other half did not experience the same success.
Findings
As an overall result, the expatriate journey for young footballers is complex, influenced by many events, expectations, conditions and pressures that affect their support web and ability to adjust. Reflecting on the experiences of successful transitions, problem-focused coping strategies have been more effective than emotion-focused coping.
Research limitations/implications
This study highlights some necessary conditions and coping strategies for young self-initiated sports expatriates to cope with the expatriate transition successfully.
Originality/value
The authors contribute to research on expatriation, as this specific group of “young professionals” has not yet been addressed by the research within international human resource management. Our research framework responds to calls in the literature to consider additional stages of player development and an array of individual and cultural factors that may have a significant role in shaping players’ careers abroad.

Abstract
Purpose
The purpose of this paper is to use autoethnography to explore notions of self-identity formation and projection. The author uses the stages of grief as an analytical tool to explain athletic identity formation and personal effects when an injury removed that part of her self.
Design/methodology/approach
The paper uses autoethnography, a self-reflective, qualitative methodology meant to engage the researcher's personal experience, which then is potentially adapted and understood by others in similar situations. Autoethnography might pair personal research with existing analytical frameworks and theories, as this story does.
Findings
–The author realized that losing, even temporarily, self-identifying characteristics (here, athletic identity) affects self-esteem, social interactions, and future motion-based endeavors, for fear of starting the cycle of grief again.
Originality/value
The paper is valuable, as many people are “weekend warrior” athletes that identity as a runner, cyclist, triathlete, weight lifter, or general gymgoer. Someone might sustain an injury that leaves him or her feeling similar to the author – and can help them understand the importance of athletic identity. The paper also shows how a well-known framework, stages of grief, can be used not solely as an explanatory tool but an analytical one as well.

Abstract
Purpose
The purpose of this paper is to introduce new non‐classical implementations of neural networks (NNs). The developed implementations are performed in the quantum, nano, and optical domains to perform the required neural computing. The various implementations of the new NNs utilizing the introduced architectures are presented, and their extensions for the utilization in the non‐classical neural‐systolic networks are also introduced.
Design/methodology/approach
The introduced neural circuits utilize recent findings in the quantum, nano, and optical fields to implement the functionality of the basic NN. This includes the techniques of many‐valued quantum computing (MVQC), carbon nanotubes (CNT), and linear optics. The extensions of implementations to non‐classical neural‐systolic networks using the introduced neural‐systolic architectures are also presented.
Findings
Novel NN implementations are introduced in this paper. NN implementation using the general scheme of MVQC is presented. The proposed method uses the many‐valued quantum orthonormal computational basis states to implement such computations. Physical implementation of quantum computing (QC) is performed by controlling the potential to yield specific wavefunction as a result of solving the Schrödinger equation that governs the dynamics in the quantum domain. The CNT‐based implementation of logic NNs is also introduced. New implementations of logic NNs are also introduced that utilize new linear optical circuits which use coherent light beams to perform the functionality of the basic logic multiplexer by utilizing the properties of frequency, polarization, and incident angle. The implementations of non‐classical neural‐systolic networks using the introduced quantum, nano, and optical neural architectures are also presented.
Originality/value
The introduced NN implementations form new important directions in the NN realizations using the newly emerging technologies. Since the new quantum and optical implementations have the advantages of very high‐speed and low‐power consumption, and the nano implementation exists in very compact space where CNT‐based field effect transistor switches reliably using much less power than a silicon‐based device, the introduced implementations for non‐classical neural computation are new and interesting for the design in future technologies that require the optimal design specifications of super‐high speed, minimum power consumption, and minimum size, such as in low‐power control of autonomous robots, adiabatic low‐power very‐large‐scale integration circuit design for signal processing applications, QC, and nanotechnology.

Abstract
The current crisis of sociological theory is due to our failure to do sociology as a positive science‐our failure to accept both explanation and prediction as the goal of theorizing, and to use predictive power as the primary criterion for assessing theories. It is argued that sociology as a positive science can advance sociological theory. It is also argued that a positive science of sociology is possible by correcting four major fallacies‐i.e., fallacies concerning controlled experiments, realism of assumptions, subjectivity, and complexity.

Abstract
Purpose
Gender inequalities in higher education have attracted interest in the academic literature. The paper aims to discuss this issue.
Design/methodology/approach
The author uses standardized high school final exam results and probit regression analysis to contribute to this highly important discussion.
Findings
Based on secondary, non-survey data, female students tend to outperform males in subjects requiring creativity. Consistent with this comparative advantage, female students also tend to be more affected by their abilities in choosing and preferring the related field of humanities as a higher education. In line with female students’ choices, the results presented in the paper confirm that men are more inclined toward exact and natural sciences, even though they do not prove to have stronger abilities in related subjects. In addition, men are also more influenced by their abilities in obtaining a professional higher education. The choice of social sciences is quite similarly affected by the academic abilities of men and women. The paper also provides evidence that, on average, individuals choose their field of study according to their academic abilities.
Originality/value
For evidence, a data set that makes it possible to relate quantitative measures of very different academic abilities to all major academic disciplines is used in the paper. This unique approach has so far been lacking in the literature due to data limitations. In other words, instead of concentrating on a specific area, such as science, technology, engineering, and mathematics (STEM), the author takes a broader view.

Abstract
Although waiting on the Internet is widely recognised as a crucial factor in the evolution of e‐commerce and the Internet in general, it is not a widespread topic of research. This article identifies and reviews 21 papers based on 13 separate empirical studies on waiting on the Internet. The literature draws from the areas of marketing, system response time studies and quality of service studies. Having reviewed the existing literature, this article proposes an agenda for future research. Recommendations are made to extend the range of research methodologies applied to this topic, to broaden the definition of waiting on the Internet to include other forms of online waiting, and to continue the interdisciplinary approach to research on online waiting.

Abstract
Through the use of computer simulation of three biogeochemical cycles—carbon, nitrogen, and phosphorus—we have shown that DDT poisoning of ocean producers (plants) can cause their growth to be limited by nitrogen, whereas ordinarily it is limited by phosphorus. We must qualify what we have shown because we restricted the simulation by representing only two ecosystems (ocean and land), by using simplified equations for some flow rates, and finally by estimating data for some biomass values and for some flow rates. In order to remove some of the restrictions on the simulation, we are extending it so that we may include in it knowledge of our own, of ecologists, and of systems analysts. By extending it, we are increasing our ability for using it to understand, and consequently to predict and control, the behavior of the interacting biogeochemical cycles of the world.

Abstract
Purpose
To investigate the general necessary condition for synthesis of square, real rational matrices of complex frequency as admittance matrices of active multiports with resistors, inductors, capacitors and possibly multiport transformers and to prove that this condition is also sufficient for synthesis of stable, square, real rational matrices of complex frequency as admittance matrices of balanced active multiports having only resistors, capacitors and voltage‐amplifiers with sufficiently large amplifications. The main aim of the paper is to provide a new and general method for stable admittance matrices synthesis and to develop strict realization algorithm by active balanced transformerless multiport networks.
Design/methodology/approach
The objectives of the paper are achieved by using factorization of regular polynomial matrices in complex frequency with certain degree as products of other regular polynomial matrices with specified degrees. A set of sufficient conditions for such a factorization is presented and derived a pertinent algorithm as the starting point for investigation and solving network synthesis problem and generation of class of equivalent realizations.
Findings
Theorem 1 states that sufficient condition for factorization of Pth order, generally regular polynomial matrix P(s) in complex frequency s with degree L, whose determinant has K distinct zeros, in form P(s)=P1(s)·P2(s), where 1≤p2=P20≤L−1 is degree of polynomial matrix P2(s), reads: K>(P−1)·L+p2−1. The coefficient‐matrices of s, s2,… in P1(s) and P2(s) are real or complex depending on whether distinct zeros of det P(s) are real or complex, respectively. Theorem 2 states that: (a) for realization of Pth order matrix of real rational functions in complex frequency s (i.e. RRF matrix) as admittance matrix of active balanced RLC P‐port network with multiport transformers, or without them, P generalized controlled‐sources and P controlling‐ports are necessary, in general; and (b) P balanced voltage‐controlled voltage‐sources (VCVSs) with real and by module greater than unity controlling coefficients (“voltage amplifications”) are sufficient for realization of stable admittance RRF matrix by active, balanced, transformerless, RC P‐port network.
Originality/value
This is a research paper with the following two main contributions (original results). First, a theorem on sufficient conditions for factorization of regular polynomial matrices in complex frequency; and second, a theorem relating to sufficient conditions for synthesis of matrices of real rational functions in complex frequency by active, balanced, transformerless networks. The results may be interesting for network theorists and researchers in the field of electric circuits and systems.

The purpose of this paper is to better understand the selection of a distribution channel strategy for a non‐profit organization selling products or services to its end customers.
Abstract
Purpose
The purpose of this paper is to better understand the selection of a distribution channel strategy for a non‐profit organization selling products or services to its end customers.
Design/methodology/approach
Two channel strategies are generally considered: an integrated channel where the non‐profit organization sells its products or services using its own selling departments or branches; and a decentralized channel where the non‐profit organization sells through a for‐profit retailer. The fundamental question is: how should a non‐profit organization select its distribution channel strategy under certain market conditions?
Findings
It was found that selecting a decentralized channel strategy results in an optimal retail price that is higher than that under an integrated channel strategy, which results in lower customer welfare under the decentralized channel. It was also found that a decentralized channel behaves as an integrated fully for‐profit channel. Thus, whether a non‐profit organization should choose an integrated or a decentralized channel when facing competition from an integrated or a decentralized fully for‐profit channel depends on its cost structure and the level of substitutability of the products or services offered by the two channels.
Practical implications
When competing with an integrated fully for‐profit channel, the non‐profit organization is better off using an integrated channel under strong competition or a decentralized channel under weak competition. When competing with a decentralized fully for‐profit channel, the selection is more complicated. It was found that a decentralized channel is the best choice if the price competition factor, where threshold value depends on the cost structure, is large.
Originality/value
Non‐profit organizations have a clear (perhaps increasing) need for distribution centers or retailers in order to reach people who need their products or services. Moreover, it has been reported that the interactions between for‐profit and non‐profit sectors continue to grow, thus increasing the forms of community involvement available to reach people. It is thus clear that additional research is needed to better understand the selection of a distribution channel strategy for a non‐profit organization selling products or services to its end customers, and also the related managerial implications.
