In this article, a multiple relay selection (MRS) scheme for signal-to-noise ratio (SNR) enhancement is proposed for underlay relay-assisted cognitive radio networks (RCRNs). A secondary source-destination pair experiencing deep fading on direct path is assisted by amplify-and-forward (AF) relays in an underlay mode. In this energy-constrained scenario, the aim is to maximize the secondary network's end-to-end SNR through an intelligent power-saving method incorporated with MRS. In contrast to the prior relay selection (RS) schemes, the relay-selection factor is the difference of SNR of the source-relay link and corresponding relay-destination link for each relay along with its corresponding interference channel coefficient. The difference factor aims to achieve the SNR upper bound while performing minimum power amplification, eventually resulting in interference mitigation as well. The proposed algorithm has been implemented using Fuzzy Rule Based System (FRBS), Artificial Bee Colony (ABC) and Particle Swarm Optimization (PSO) and their performance has been compared through simulations.

In wireless communication systems, reliability, low latency and power are essential in large scale multi-hop environment. Multi-hop based cooperative communication is an efficient way to achieve goals of wireless networks. This paper proposes a relay selection scheme for reliable transmission by selecting an optimal relay. The proposed scheme uses a signal-to-noise ratio (SNR) based Q-learning relay selection scheme to select an optimal relay in multi-hop transmission. Q-learning consists of an agent, environment, state, action and reward. When the learning is converged, the agent learns the optimal policy which is a rule of the actions that maximize the reward. In other words, the base station (BS) knows the optimal relay to select and transmit the signal. At this time, the cooperative communication scheme used in this paper is a decode-and-forward (DF) scheme in orthogonal frequency division multiplexing (OFDM) system. The Q-learning in the proposed scheme defines an environment to maximize a reward which is defined as SNR. After the learning process, the proposed scheme finds an optimal policy. Furthermore, this paper defines a reward which is based on the SNR. The simulation results show that the proposed scheme has the same bit error rate (BER) performance as the conventional relay selection scheme. However, this paper proposes an advantage of selecting fewer relays than conventional scheme when the target BER is satisfied. This can reduce the latency and the waste of resources. Therefore, the performance of the multi-hop transmission in wireless networks is enhanced.

Cooperative relaying is an effective technology to improve the capacity of physical-layer security, in which the relay helps forward the received signal to the destination. In this paper, a cooperative compressive sensing and amplify-and-forward (CCS-AF) scheme, which combines the compressive sensing theory and amplify-and-forward strategy, is proposed to increase the secrecy capacity. To optimize the secrecy performance, a coalition formation algorithm based on coalitional game theory of optimal relay selection is proposed to maximize the secrecy capacity. Different to maximizing the individual utility based on the traditional pareto order, the max-coalition order rule is newly defined to guide the coalitional formation. Simulation results indicate that with the proposed algorithm, part of the relays could form a coalition to forward the information and the proposed algorithm could significantly improve the secrecy capacity of cooperative multi-relay networks.

Data delivery in vehicular networks (VANETs) is a challenging task due to the high mobility and constant topological changes. In common routing protocols, multihop V2V communications suffer from higher network delay and lower packet delivery ratio (PDR), and excessive dependence on GPS may pose threat on individual privacy. In this paper, we propose a novel data delivery scheme for vehicular networks in urban environments, which can improve the routing performance without relying on GPS. A fuzzy-rule-based wireless transmission approach is designed to optimize the relay selection considering multiple factors comprehensively, including vehicle speed, driving direction, hop count, and connection time. Wireless V2V transmission and wired transmissions among RSUs are both utilized, since wired transmissions can reduce the delay and improve the reliability. Each RSU is equipped with a machine learning system (MLS) to make the selected relay link more reliably without GPS through predicting vehicle speed at next moment. Experiments show the validity and rationality of the proposed method.

In order to improve the energy efficiency (EE) performance of cooperative networks, this study combines non-orthogonal multiple access (NOMA) with simultaneous wireless information and power transfer (SWIPT) technologies to construct a cooperative relay network composed of one base station (BS), multiple near users, and one far user. Based on the network characteristics, a time-division resource allocation rule is proposed, and EE formulas regarding direct-link mode and cooperative mode are derived. Considering user selection and decoding performance, to obtain the optimal EE, this study utilizes a DinkelBach iterative algorithm based on the golden section (GS-DinkelBach) to solve the EE optimization problem, which is affected by power transmitted from the BS, achievable rates under three communication links, and quality of service (QoS) constraints of users. The simulation results show that the GS-DinkelBach algorithm can obtain precise EE gains with low computational complexity. Compared with the traditional NOMA–SWIPT direct-link network model and the relay network model, the optimal EE of the established network model could be increased by 0.54 dB and 1.66 dB, respectively.

Road-based directional broadcast protocols are proposed in the literatures to offset efficiency of message dissemination of traditional broadcast protocol in urban vehicular ad hoc networks. However, these protocols cannot provide enough reliability and efficiency for vehicles’ misclassification at intersection or on straight road. Therefore, we present regular-hexagon-equilateral-triangle area grouping–based broadcast protocol for urban vehicular ad hoc networks. The area covered by relay node is averagely divided using regular-hexagon-equilateral-triangle, and vehicles are grouped according to the area that they reside. The algorithm for constructing regular-hexagon-equilateral-triangle is proposed. We adopt same vehicles’ grouping method at intersection and on straight road, and no neighbor list is maintained to identify road intersection. We design waiting time formula to calculate time for node forwarding message. It is ruled that node with waiting time dropping to zero first is defined as the relay node, and this relay node transmits message. So there is only one relay node which forwards message in each group. It also rules in regular-hexagon-equilateral-triangle area grouping–based broadcast protocol that each relay node forwards the same message only once, therefore, it limits redundant message retransmission. Using the vehicles’ grouping method and selection strategy of relay node as mentioned above, the proposed protocol enables message to be transmitted in different directions along different roads at the same time. Simulation indicates that our protocol has a better performance

The rate-limiting steps of the electrolysis of water solution, taking into account hydrogen evolution overpotential were considered. A functional relationship between the electrical resistivity of 3–5 dm metals and their quantization energy of atomic electrons, as well as the coordination of metal atoms and hydrogen compounds, has been revealed. The rule of selecting effective metals for cathodes has been validated. Based on these rules, a reduction-relay mechanism of the hydrogen migration process in the electrical double layer in the electrochemical reduction of TiO2+ ions to Ti3+ and Fe3+ to Fe2+ in sulfuric acid process solutions for the production of pigment titanium dioxide was proposed. The method of the multistage electrochemical reduction of Fe3+ and [TiO2+ * nH2O] in process solutions for the production of titanium dioxide was design based on this study.

Systematized existing methods of calculation verification of current transformers that work in the circuits of modern relay protection devices. The requirements of the Ukrainian rules for the arrangement of electrical installations differ from the requirements of the standard of the International Electrotechnical Commission IES 61869-2. The difference concerns the absence of contact vibration and not exceeding the maximum allowable current error of 50% in the case of an internal short circuit is a separate case of the requirements for electromechanical protections and these requirements cannot be used for microprocessor protection devices. For any relay protection device, there is no concept of the permissible value of "voltages at the current inputs". The voltage at the terminals of the secondary winding and the voltage at the "input of the relay protection device" are two completely different voltages. There are no methods for calculating errors in the case of switching on protection based on the sum of the currents. Companies producing microprocessor relay protection devices specify in their instructions individual requirements for current transformers for each individual device. Compliance with these requirements guarantees the correct operation of the relay protection even for large values of the time constant of the primary network. Leading manufacturers of microprocessor relay protection devices develop and recommend software tools for checking the correct selection of current transformers. But they are not freely available. To increase the accuracy of the calculation of the limit multiplicity, it is advisable to use complex supports of the secondary winding and load of current transformers. Depending on the initial data and conditions, the permissible load resistance can be calculated using four methods. The question of whether the allowable load of a current transformer can exceed its nominal load requires further research. The scientific novelty is consists in the systematization of existing methods of calculation verification of current transformers that work in the circles of modern relay protection devices. The practical significance of the work is that checking current transformers that are connected to microprocessor relay protection devices do not need to check the maximum permissible current error of 50%; to check the correct operation of microprocessor relay protection devices, it is advisable to use the instructions for the requirements for current transformers of device manufacturers; for a more accurate calculation of the limit multiplicity, it is advisable to use complex supports of the secondary winding and load of current transformers.

While Jesuits composed more Latin didactic poetry than any other order or profession in the early modern period, they—perhaps surprisingly—rarely chose moral, political, or spiritual subjects for versification in this genre. One of the few exceptions to the rule is Prudentia, prolusio didascalica (Prudence, a didactic prolusion) by the Paduan-born Jesuit Giannantonio Bernardi (1670–1743), first published in Venice in 1709. Bernardi seems to have spent his whole life as a teacher, preacher, and confessor in northern Italy, apart from a stint accompanying his penitent, the Venetian envoy and future Doge, Carlo Ruzzini, to Constantinople. This paper sets Bernardi’s didactic poem in the context of some other Jesuit didactic poems of moral or spiritual counsel, especially Pierre Mambrun’s Psychourgicon: De cultura animi (La Flèche: ex officina Gervasii Laboe, 1661), as well as a selection of his other moral writings. It finds the Jesuit dimension to Bernardi’s poem more in its literary and institutional contexts and paratexts than in the bare philosophical doctrine it relays.

The goal of task transfer in reinforcement learning is migrating the action policy of an agent to the target task from the source task. Given their successes on robotic action planning, current methods mostly rely on two requirements: exactlyrelevant expert demonstrations or the explicitly-coded cost function on target task, both of which, however, are inconvenient to obtain in practice. In this paper, we relax these two strong conditions by developing a novel task transfer framework where the expert preference is applied as a guidance. In particular, we alternate the following two steps: Firstly, letting experts apply pre-defined preference rules to select related expert demonstrates for the target task. Secondly, based on the selection result, we learn the target cost function and trajectory distribution simultaneously via enhanced Adversarial MaxEnt IRL and generate more trajectories by the learned target distribution for the next preference selection. The theoretical analysis on the distribution learning and convergence of the proposed algorithm are provided. Extensive simulations on several benchmarks have been conducted for further verifying the effectiveness of the proposed method.

AbstractIn this study, we present a transfer learning method for gesture classification via an inductive and supervised transductive approach with an electromyographic dataset gathered via the Myo armband. A ternary gesture classification problem is presented by states of ’thumbs up’, ’thumbs down’, and ’relax’ in order to communicate in the affirmative or negative in a non-verbal fashion to a machine. Of the nine statistical learning paradigms benchmarked over 10-fold cross validation (with three methods of feature selection), an ensemble of Random Forest and Support Vector Machine through voting achieves the best score of 91.74% with a rule-based feature selection method. When new subjects are considered, this machine learning approach fails to generalise new data, and thus the processes of Inductive and Supervised Transductive Transfer Learning are introduced with a short calibration exercise (15 s). Failure of generalisation shows that 5 s of data per-class is the strongest for classification (versus one through seven seconds) with only an accuracy of 55%, but when a short 5 s per class calibration task is introduced via the suggested transfer method, a Random Forest can then classify unseen data from the calibrated subject at an accuracy of around 97%, outperforming the 83% accuracy boasted by the proprietary Myo system. Finally, a preliminary application is presented through social interaction with a humanoid Pepper robot, where the use of our approach and a most-common-class metaclassifier achieves 100% accuracy for all trials of a ‘20 Questions’ game.

Concurrent rainbow trout (Oncorhynchus mykiss) stomach contents and invertebrate drift samples were collected during three 24-h periods in summer 1987. Feeding was discontinuous through the day on all dates. Mean stomach content weight was minimal after 0400 MST and sharply increased between 1000 and 1200 MST on all three dates. Feeding apparently did not occur after twilight. Mean stomach content weight was correlated with water temperature on two dates and was never correlated with invertebrate drift density for non-age-0 trout. Daily ration (wet weight) was 7% of live weight for non-age-0 trout and 21% for age-0 trout. Trichoptera, Ephemeroptera, and Diptera were most important in the diet; terrestrial insects and aquatic vertebrates were rare. The degree of selectivity varied through 24 h and the interpretation depended on the method of analysis used. Occurrence of low-drift cased Trichoptera larvae in stomachs was correlated with amount of filamentous algae ingested, indicating a degree of epibenthic foraging, although no diel pattern could be reliably discerned. Mean length of prey items in stomachs was larger that the drift in 83% of the samples. Our findings support experimentally derived decision rules-of-thumb for foraging trout: select larger prey items, select vulnerable prey, and relax selectivity when hungry.

Cosmological tensions in current times have opened a wide door to study new probes to constrain cosmological parameters, specifically, to determine the value of the Hubble constant H0 through independent techniques. The two standard methods to measure/infer H0 rely on: (i) anchored observables for the distance ladder, and (ii) establishing the relationship of the H0 to the angular size of the sound horizon in the recombination era assuming a standard Cosmological Constant Cold Dark Matter (ΛCDM) cosmology. However, the former requires a calibration with observables at nearby distances, while the latter is not a direct measurement and is model-dependent. The physics behind these aspects restrains our possibilities in selecting a calibration method that can help minimise the systematic effects or in considering a fixed cosmological model background. Anticipating the possibility of deeply exploring the physics of new nearby observables such as the recently detected black hole shadows, in this paper we propose standard rules to extend the studies related to these observables. Supermassive black hole shadows can be characterised by two parameters: the angular size of the shadow and the black hole mass. We found that it is possible to break the degeneracy between these parameters by forecasting and fixing certain conditions at high(er) redshifts, i.e., instead of considering the ≈10% precision from the EHT array, our results reach a ≈4%, a precision that could be achievable in experiments in the near future. Furthermore, we found that our estimations provide a value of H0=72.89±0.12 km/s/Mpc and, for the baryonic mass density, Ωm=0.275±0.002, showing an improvement in the values reported so far in the literature. We anticipate that our results can be a starting point for more serious treatments of the physics behind the SMBH shadow data as cosmological probes to relax tension issues.

The article aims at analyzing the current situation with the sustainable development of an enterprise, which is reached by increasing the credit resources efficiency. The correlation between sustainable development of an enterprise and its creditworthiness has been proved. The level of the Global Competitiveness Index of Ukrainian enterprises in the world economy has been studied. The line of business analyses of the current industrial environment has been carried out, thus sketching the general situation in Ukraine. Features hindering the sustainable development of business have been analyzed. Research has been provided as for the ratings of the most popular banks for business. The main advantages and disadvantages of loans to business persons have been suggested taking into account the average interest rates on such loans. It has been found out that the main factor for obtaining loans by business persons is their financial standing. Therefore, if a business person or company can repay their loans and interest on existing liabilities on time in full, this fact becomes a favorable and important factor for creditors. It has been found out that current loan rates are too high and thus become too expensive for many companies to attract additional funds for their business, the reason being the non-repayment of loans to banks. It is concluded that one of the central problems Ukraine is now facing is the mismanagement of sustainable development of enterprises, and problems in using credit resources suggested by banks are among the main factors here. It is determined that Ukrainian enterprises have all the chances to become the main carrier of technical progress and a source of growth of national competitiveness, but in order for it to start approaching the development level of the world's leading countries, significant financial resources are required. It has been proved that attention should mainly be focused on developing and improving strategic directions of sustainable development management related to attracting credit resources, namely suggesting the rules for and implementing the process of selecting and providing further state support for the best possible investment projects, which could improve the sustainable development of entrepreneurship and increase the efficiency of using credit resources in long-term business projects.

This paper proposes a routing algorithm of cluster tree network and further combines the hierarchical structure of clustering with that of neural network, and designs a data fusion algorithm based on clustering routing protocol. Then, aiming at the difficulty in selecting the weights of neural network, a weight optimization neural network based on particle swarm optimization algorithm is proposed and applied to multi-sensor fusion. The simulation results show that the number of cluster heads of ACEC protocol is more concentrated on the expected value and has good stability. The algorithm selects cluster head nodes by non-uniform clustering and dynamic threshold, which ensures the balanced distribution of cluster head nodes in the network, reduces the network energy consumption and prolongs the service life of the network. The success rate of ancec protocol is similar to debug protocol, but with the increase of transmission time, LEACH protocol and debug protocol do not consider the link quality factor when forwarding data, so the communication link quality is uneven when selecting the next hop relay point in each round, so the data transmission success rate has a relatively obvious downward trend. The fusion result is clearly better than the poor two sensors, but inferior to the best sensor. This is due to the low SNR of sensors SNL and SN2, so their recognition effect is relatively poor, which also conforms to the rule of multi-sensor fusion. The results show that the method based on qdpso-bp network fusion is feasible.

Forssen Ehrlin, Carl-Johan. The Rabbit Who Wants to Fall Asleep: A New Way of Getting Children to Sleep. Illus. Irina Maununan. New York: Crown Books for Young Readers, 2014. Print.Carl-Johan Forssen Ehrlin, the psychologist who wrote this book, introduces the work with instructions for its calm, slow, emphatic reading. He then begins the bedtime story proper, a ten page text in which he uses the word sleep or one of its variants (asleep, sleeping, sleepy) approximately 100 times. It may be that he uses the words “yawn,” “tired,” and “relax” just as frequently; frankly, it seems too daunting a task to count and confirm this possibility. The literary effect is tedious—given the subtitle, probably intentionally so. There is a storyline, albeit a thin one. It is much enhanced by the delicate drawings by Irina Maununen; a young child might well pore over these. However, storytelling is not the main purpose of the book. Its main purpose would appear to be hypnosis. That is just a guess; the publisher’s blurb does not actually confirm it. The blurb does, however, rave about the book’s ability to put children to sleep. Quite so. This is not a work of children’s literature; it is a “how to” book for adults. Its advice should not replace common sense. Childhood sleeplessness can stem from serious causes. It can be the result of underlying medical conditions, of pain, of breathing difficulties. It can indicate worrisome psychological states: stress, anxiety, and fear. It can be the result of a socio-economic environment that is typified by deprivation and hunger, domestic instability, the presence of danger. A book outlining hypnotic techniques does not obviate any of these root causes of sleeplessness. However, in the event that they are all ruled out or remedied, and that a child is found to suffer from nothing more than a deep need for the comforting presence of a loving adult as he or she falls asleep, why not just ensure that one can be there?All this being said, the book is currently popular. As I write this review, my public library lists thirty holds on fourteen copies of it. Many parents must be waiting in line for an introduction to Forssen-Ehrlin’s methods. Meanwhile, the old standbys of sleep induction, the rocking, the reassuring, the crooning of lullabies, might just prove equally effective as his book.Not RecommendedReviewer: Leslie AitkenLeslie Aitken’s long career in librarianship involved selection of children’s literature for school, public, special and academic libraries.

Introduction Historically in Australia, there has been a growing movement behind the development of quality Early Childhood Education and Care Centres (termed ‘centres’ for this article). These centres are designed to provide care and education outside of the home for children from birth to five years old. In the mid 1980s, the then Labor Government of Australia promoted and funded the establishment of many centres to provide women who were at home with children the opportunity to move into the workplace. Centre fees were heavily subsidised to make this option viable in the hope that more women would become employed and Australia’s rising unemployment statistics would be reduced. The popularity of this system soon meant that there was a childcare centre shortage and parents were faced with long waiting lists to enrol their child into a centre. To alleviate this situation, independent centres were established that complied with Government rules and regulations. Independent, state, and local government funded centres had a certain degree of autonomy over facilities, staffing, qualifications, quality programmes, and facilities. This movement became part of the global increased focus on the importance of early childhood education. As part of that educational emphasis, the Melbourne Declaration on Educational Goals for Young Australians in 2008 set the direction for schooling for the next 10 years. This formed the basis of Australia’s Education Reforms (Department of Education, Employment and Workplace Relations). The reforms have influenced the management of early childhood education and care centres. All centres must comply with the National Quality Framework that mandates staff qualifications, facility standards, and the ratios of children to adults. From a parent’s perspective centres now look very much the same. All centres have indoor and outdoor playing spaces, separate rooms for differently aged children, playgrounds, play equipment, foyer and office spaces with similarly qualified staff. With these similarities in mind, the dilemma for parents is how to decide on a centre for their child to attend. Does it come down to parents’ taste about a centre? In the education context, how is taste conceptualised? This article will present research that conceptualises taste as being part of a decision-making process (DMP) that is used by parents when choosing a centre for their child and, in doing so, will introduce the term: parental taste. The Determining Factors of Taste A three phase, sequential, mixed methods study was used to determine how parents select one centre over another. Cresswell described this methodology as successive phases of data collection, where each builds on the previous, with the aim of addressing the research question. This process was seen as a method to identify parents’ varying tastes in centres considered for their child to attend. Phase 1 used a survey of 78 participants to gather baseline data to explore the values, expectations, and beliefs of the parents. It also determined the aspects of the centre important to parents, and gauged the importance of the socio-economic status and educational backgrounds of the participants in their decision making. Phase 2 built on the phase 1 data and included interviews with 20 interviewees exploring the details of the decision-making process (DMP). This phase also elaborated on the survey questions and responses, determined the variables that might impact on the DMP, and identified how parents access information about early learning centres. Phase 3 focussed on parental satisfaction with their choice of early learning setting. Again using 20 interviewees, these interviews investigated the DMP that had been undertaken, as well as any that might still be ongoing. This phase focused on parents' reflection on the DMP used and questioned them as to whether the same process would be used again in other areas of decision making. Thematic analysis of the data revealed that it usually fell to the mother to explore centre options and make the decision about enrolment. Along the way, she may have discussions with the father and, to a lesser extent, with the centre staff. Friends, relatives, the child, siblings, and other educational professionals did not rank highly when the decision was being considered. Interestingly, it was found that the mother began to consider childcare options and the need for care twelve months or more before care was required and a decision had to be made. A small number of parents (three from the 20) said that they thought about it while pregnant but felt silly because they “didn’t even have a baby yet.” All mothers said that it took quite a while to get their head around leaving their child with someone else, and this anxiety and concern increased the younger the child was. Two parents had criteria that they did not want their child in care until he/she could talk and walk, so that the child could look after him- or herself to some extent. This indicated some degree of scepticism that their child would be cared for appropriately. Parents who considered enrolling their child into care closer to when it was required generally chose to do this because they had selected a pre-determined age that their child would go into childcare. A small number of parents (two) decided that their child would not attend a centre until three years old, while other parents found employment and had to find care quickly in response. The survey results showed that the aspects of a centre that most influenced parental decision-making were the activities and teaching methods used by staff, centre reputation, play equipment inside and outside the centre, and the playground size and centre buildings. The interview responses added to this by suggesting that the type of playground facilities available were important, with a natural environment being preferred. Interestingly, the lowest aspect of importance reported was whether the child had friends or family already attending the centre. The results of the survey and interview data reflected the parents’ aspirations for their child and included the development of personal competencies of self-awareness, self-regulation, and motivation linking emotions to thoughts and actions (Gendron). The child’s experience in a centre was expected to develop and refine personal traits such as self-confidence, self-awareness, self-management, the ability to interact with others, and the involvement in educational activities to achieve learning goals. With these aspirations in mind, parents felt considerable pressure to choose the environment that would fit their child the best. During the interview stage of data collection, the term “taste” emerged. The term is commonly used in a food, fashion, or style context. In the education context, however, taste was conceptualised as the judgement of likes and dislikes regarding centre attributes. Gladwell writes that “snap judgements are, first of all, enormously quick: they rely on the thinnest slices of experience. But they are also unconscious” (50). The immediacy of determining one's taste refutes the neoliberal construction (Campbell, Proctor, Sherington) of the DMP as a rational decision-making process that systematically compares different options before making a decision. In the education context, taste can be reconceptualised as an alignment between a decision and inherent values and beliefs. A personal “backpack” of experiences, beliefs, values, ideas, and memories all play a part in forming a person’s taste related to their likes and dislikes. In turn, this effects the end decision made. Parents formulated an initial response to a centre linked to the identification of attributes that aligned with personal values, beliefs, expectations, and aspirations. The data analysis indicated that parents formulated their personal taste in centres very quickly after centres were visited. At that point, parents had a clear image of the preferred centre. Further information gathering was used to reinforce that view and confirm this “parental taste.” How Does Parental Taste about a Centre Influence the Decision-Making Process? All parents used a process of decision-making to some degree. As already stated, it was usually the mother who gathered information to inform the final decision, but in two of the 78 cases it was the father who investigated and decided on the childcare centre in which to enrol. All parents used some form of process to guide their decision-making. A heavily planned process sees the parent gather information over a period of time and included participating in centre tours, drive-by viewings, talking with others, web-based searches, and, checking locations in the phone book. Surprisingly, centre advertising was the least used and least effective method of attracting parents, with only one person indicating that advertising had played a part in her DMP. This approach applied to a woman who had just moved to a new town and was not aware of the care options. This method may also be a reflection of the personality of the parent or it may reflect an understanding that there are differences between services in terms of their focus on education and care. A lightly planned process occurred when a relatively swift decision was made with minimal information gathering. It could have been the selection of the closest and most convenient centre, or the one that parents had heard people talk about. These parents were happy to go to the centre and add their name to the waiting list or enrol straight away. Generally, the impression was that all services provide the same education and care. Parents appeared to use different criteria when considering a centre for their child. Aspects here included the physical environment, size of rooms, aesthetic appeal, clean buildings, tidy surrounds, and a homely feel. Other aspects that affected this parental taste included the location of the centre, the availability of places for the child, and the interest the staff showed in parent and child. The interviews revealed that parents placed an importance on emotions when they decided if a centre suited their tastes that in turn affected their DMP. The “vibe,” the atmosphere, and how the staff made the parents feel were the most important aspects of this process. The centre’s reputation was also central to decision making. What Constructs Underpin the Decision? Parental choice decisions can appear to be rational, but are usually emotionally connected to parental aspirations and values. In this way, parental choice and prior parental decision making processes reflect the bounded rationality described by Kahneman, and are based on factors relevant to the individual as supported by Ariely and Lindstrom. Ariely states that choice and the decision making process are emotionally driven and may be irrational-rational decisions. Gladwell supports this notion in that “the task of making sense of ourselves and our behaviour requires that we acknowledge there can be as much value in the blink of an eye as in months of rational analysis” (17). Reay’s research into social, cultural, emotional, and human capital to explain human behaviour was built upon to develop five constructs for decision making in this research. The R.O.P.E.S. constructs are domains that tie together to categorise the interaction of emotional connections that underpin the decision making process based on the parental taste in centres. The constructs emerged from the analysis of the data collected in the three phase approach. They were based on the responses from parents related to both their needs and their child’s needs in terms of having a valuable and happy experience at a centre. The R.O.P.E.S. constructs were key elements in the formation of parental taste in centres and eventual enrolment. The Reputational construct (R) included word of mouth, from friends, the cleaner, other staff from either the focus or another centre, and may or may not have aligned with parental taste and influenced the decision. Other constructs (O) included the location and convenience of the centre, and availability of spaces. Cost was not seen as an issue with the subsidies making each centre similar in fee structure. The Physical construct (P) included the facilities available such as the indoor and outdoor play space, whether these are natural or artificial environments, and the play equipment available. The Social construct (S) included social interactions—sharing, making friends, and building networks. It was found that the Emotional construct (E) was central to the process. It underpinned all the other constructs and was determined by the emotions that were elicited when the parent had the first and subsequent contact with the centre staff. This construct is pivotal in parental taste and decision making. Parents indicated that some centres did not have an abundance of resources but “the lady was really nice” (interview response) and the parent thought that her child would be cared for in that environment. Comments such as “the lady was really friendly and made us feel part of the place even though we were just looking around” (interview response) added to the emotional connection and construct for the DMP. The emotional connection with staff and the willingness of the director to take the time to show the parent the whole centre was a common comment from parents. Parents indicated that if they felt comfortable, and the atmosphere was warm and homelike, then they knew that their child would too. One centre particularly supported parental taste in a homely environment and had lounges, floor rugs, lamps for lighting, and aromatherapy oil burning that contributed to a home-like feel that appealed to parents and children. The professionalism of the staff who displayed an interest in the children, had interesting activities in their room, and were polite and courteous also added to the emotional construct. Staff speaking to the parent and child, rather than just the parent, was also valued. Interestingly, parents did not comment on the qualifications held by staff, indicating that parents assumed that to be employed staff must hold the required qualifications. Is There a Further Application of Taste in Decision Making? The third phase of data collection was related to additional questions being asked of the interviewee that required reflection of the DMP used when choosing a centre for their child to attend. Parents were asked to review the process and comment on any changes that they would make if they were in the same position again. The majority of parents said that they were content with their taste in centres and the subsequent decision made. A quarter of the parents indicated that they would make minor changes to their process. A common comment made was that the process used was indicative of the parent’s personality. A self confessed “worrier” enrolling her first child gathered a great deal of information and visited many centres to enable the most informed decision to be made. In contrast, a more relaxed parent enrolling a second or third child made a quicker decision after visiting or phoning one or two centres. Although parents considered their decision to be rationally considered, the impact of parental taste upon visiting the centre and speaking to staff was a strong indicator of the level of satisfaction. Taste was a precursor to the decision. When asked if the same process would be used if choosing a different service, such as an accountant, parents indicated that a similar process would be used, but perhaps not as in depth. The reasoning here was that parents were aware that the decision of selecting a centre would impact on their child and ultimately themselves in an emotional way. The parent indicated that if they spent time visiting centres and it appealed to their taste then the child would like it too. In turn this made the whole process of attending a centre less stressful and emotional. Parents clarified that not as much personal information gathering would occur if searching for an accountant. The focus would be centred on the accountant’s professional ability. Other instances were offered, such as purchasing a car, or selecting a house, dentist, or a babysitter. All parents suggested that additional information would be collected if their child of family would be directly impacted by the decision. Advertising of services or businesses through various multimedia approaches appeared not to rate highly when parents were in the process of decision making. Television, radio, print, Internet, and social networks were identified as possible modes of communication available for consideration by parents. The generational culture was evident in the responses from different parent age groups. The younger parents indicated that social media, Internet, and print may be used to ascertain the benefits of different services and to access information about the reputation of centres. In comparison, the older parents preferred word-of-mouth recommendations. Neither television nor radio was seen as media approaches that would attract clientele. Conclusion In the education context, the concept of parental taste can be seen to be an integral component to the decision making process. In this case, the attributes of an educational facility align to an individual’s personal “backpack” and form a like or a dislike, known as parental taste. The implications for the Directors of Early Childhood Education and Care Centres indicate that parental taste plays a role in a child’s enrolment into a centre. Parental taste is determined by the attributes of the centre that are aligned to the R.O.P.E.S. constructs with the emotional element as the key component. A less rigorous DMP is used when a generic service is required. Media and cultural ways of looking at our society interpret how important decisions are made. A general assumption is that major decisions are made in a calm, considered and rational manner. This is a neoliberal view and is not supported by the research presented in this article.

I spent more than two years in Bangladesh and lived through several incarnations—as a volunteer for aid organisations, an expatriate socialite, a bidesi (foreigner) trying to live sodesi (locally)—before becoming an ethnographer and, simultaneously, a lover and fighter of my adopted country. During the winter of my second lifetime I was sexually assaulted and at the beginning of my third lifetime, I recounted the experience at an academic conference in Dhaka. Smitten by the possibility that personal revelation could overcome cross-cultural barriers, I read A Night Out to compel others to sympathise and share, perhaps even loosen the somewhat restricted discussion of sexual intimidation in Bangladesh. Yet the response to A Night Out was quiet, absorbed by the static of courtesy, and taught me that disclosure alone cannot transcend differences to reach a space of mutual understanding. Later, when I posted A Night Out online, I observed the continued and changing capacity of revelation to evoke responses from people across genders and cultures. This article argues that the impact of revelation, although difficult to quantify, is never static and depends significantly on context: first, by describing autoethnography, a way of writing about other cultures that connects the "autobiographical and personal to the cultural, social and political" (Ellis xix), in the "Before" section to give background to A Night Out; secondly, the "After" section considers the various responses to the story and discusses it as "both a process and a product" of cultural research (xix). Before A Night Out Switching lives between Australia and Bangladesh has shown me the value of cultural research that deconstructs traditional conceptions of the "Western" and "Eastern" worlds. In terms of the representations of women, those in the East are too often prescribed the characteristics of ignorance, poverty, illiteracy, domesticity, maternity, and victimization, while the Western woman is depicted as modern, educated, in control of her body and sexuality (Gandhi 86). As a researcher, ultimately, of the life stories of Bangladeshi women, I sought to decrease the misconceptions surrounding those who were, like me, never only "West" or "East", influenced but never solely defined by their culture. Autoethnography is a method of cultural research that makes connections between "individual experience and social processes" in ways that emphasise the essential falsity of cultural categories (Sparkes 217). To transcend these boundaries of people, place and time, autoethnographers make use of narrative, believing it to be "the best way to understand the human experience" because it is "the way humans understand their own lives" (Richardson 218). As a writer, I likewise believe that narrative provides a way to make sense of or negotiate one's place in relation to any space or group of people. In particular, telling personal stories "bears fruit" of "reaching out to others," provoking their own stories and emotional responses, thereby becoming an effective cultural research method (Four Arrows 106). I remember my admiration for the Bangladeshi writer Shabnam Nadiya, who in Woman Alone describes her isolating experiences of sexual molestation as a girl and, later, the realisation via the writing of Taslima Nasrin that "it happened everywhere, everyday ... to anyone" (2008). For Nadiya, self-reflexivity created a "bridge" between the interior practise of reading and the exterior "everyday lived life" of communal experience and identity (2008). While connections on such an intimate scale may be difficult or unwelcome, making them is significant as "the process of revolution itself" (Ware 239). Inspired by Nadiya to write a piece with enough emotional power to reach over the public space of the conference room, my revelation concerned one of my own experiences as a woman in Bangladesh. A Night Out I was never afraid of my city at night. The time I liked Dhaka best was when the day wore down to dusk and the sky looked like it had been brushed clean. When I lived near Dhanmondi Lake I would walk through the drab hues of the surrounding park with its concrete paths and dusty trees that stretched their reflections across the pond-green water. The park was always crowded with raucous wallahs (vendors) and power walking women in bright dresses, yet even so I was the focus of attention, haunted by exclamations of "Koto lomba!" (How tall!) until my shadows became longer than myself in the quartzy light, and I was not so noticeable. When I moved to the Newmarket area I would spend the twilight hours sitting barefoot on my balcony in a voluminous housedress, watching Dhaka's night stage. Children played games on the rooftop of the lower apartment block opposite, women unhooked lines of fresh laundry and groups of friends would chat or play guitar. Even when the evening azan growled from the megaphones of nearby mosques there was activity on the street below, figures moving under the marigold glare of the sodium streetlights or, in winter, stretching nets across the street for badminton matches. Rickshawallahs rang their bells to the call of the crows and there was always an obnoxious motorist laying into his car horn. I felt more a part of my neighbourhood at this distance than when I became, eight floors down, the all-too-visible spectacle of the only foreigner in the district. The flat, my only source of solitude in Dhaka, was in a peaceful building set at the end of a road that turned three corners before coming to a blind halt. Walking its length day and night to reach the main thoroughfare, I got to know the road well. A few old bungalows remained, with comfortably decaying verandas behind wrought-ironwork and the shade of banana trees. Past the first corner the road became an entry for Dhaka College and the high school opposite; houses gave way to walls papered with adverts, a cluster of municipal bins surrounded by litter and wooden shacks that served cha (tea) and fried snacks. I was on friendly terms with the grey-haired wallah who stalked the area daily with his vegetable cart and one betel-chewing woman who sorted the neighbourhood rubbish. Once I neared the college attention from the chawallahs and students became more harassing than friendly, but I continued to walk to and from my house and most of the time, I walked alone. When solitude turns oppressive, the solution is to open all windows and doors and let air and friends in. One evening I invited Mia and Farad, both journalists and wine-drinkers, who arrived before sunset and stayed almost til midnight. We all knew the later it became the harder it would be for Mia to reach her home across the city. A call to one of the less dodgy cab companies proved us right—there were no taxis available in the area. It would be better, said Farad, to walk to the main road and hail a cab from there. Reluctant to end the evening at the elevator, I locked my door and joined my friends on the walk out to Mipur Road, which even at midnight stirred with the occasional activity of tradesmen and drivers. After a few attempts, Farad flagged down a cab, negotiated a fare and recorded the driver's number. It was part of the safety training Mia and I had imbibed as foreigners over the years. Other examples included "Never buy spices from the sacks at the market" and "Never wear gold necklaces while riding rickshaws." "I should catch my bus," Farad announced after Mia's departure. "But you've left your books in my house," I replied. "I thought you were coming back to get them." Farad was incredibly sexy with his brooding face and shaggy black beard and I had hoped more time would reveal reciprocal interest. From one writer to another it was not a suggestive line, but I was too shy to be more explicit with my male friends in Bangladesh, who treated me as one of the boys and silenced me sometimes with their unexpectedly conservative views of women. Farad considered my comment. "I'll collect them later, or we can meet at the university in a few days. Do you need to catch a rickshaw to your door?" "I don't have any taka on me," I said, "and it's not far." I was, after all, in my own street, not being chauffeured home by a bleary-eyed driver. "Thanks for coming! Abar dekha hobe (see you again)." "Goodnight," Farad replied and as he turned to leave I saw him grin into his beard, amused by my tipsy pronunciation. Fatigue dropped heavily on my shoulders as I strolled back down the road. My flat, with its small clean bed and softly purring ceiling fans, seemed far away at the end of the alley. It was very quiet, as quiet as home when I used to walk through the city to the train station after late night shifts on the suicide hotline. The dim light in the street exposed its emptiness. The stalls along the road had shut hours earlier and the only movement came from a middle-aged man taking his exercise, swinging his arms widely from side to side as he strode home. As I turned the first corner of the alley, another man approached me from behind. I glanced at him, probably because he had glanced at me. "Are you OK?" he asked. "Fine." "What is your country?" "Look," I said, unaccountably feeling my heart rate increase, "I'm sorry, but I don't want to talk now." "No problem, no problem," he assured me, spreading his hands and smiling, displaying two charming rows of teeth. "Relax. You're very nice." My instinct was to smile back. We walked past the waste piles that had been emptied from the bins, ready for sorting. The woman I exchanged greetings with worked here on most days and instructed me on how to wear my orna (scarf) when it wasn't placed correctly over my chest. I wondered now where she slept at night. Calculating the closeness of my friend seemed less like idle speculation when the man who was walking beside me stepped directly into my path. He was tall and lean and wore a dark blue shirt. His face gleamed, as if he had been sweating during the day and had not washed off the residue. It occurred to me to twist past him and walk faster, maybe even run. I considered how fast and how far I could go in my thongs and wondered if I should kick them off, and then start to run. "No problem," the man repeated, holding out his hands again, placing them tightly behind my neck. He pulled me towards the wall as he forced me back by moving closer. Instant wetness struck me as I felt the concrete—my pelvic floor had made the first start of surprise. The strong hands moved quickly from my neck to my breasts. "I just want to…" said the man, squeezing both breasts like he was selecting fruit. He added, "You're very nice." I was wearing the only remotely attractive bra I owned, purchased from the supermarket on Dhanmondi 27. The cups, moulded from black synthetic lace, made my chest stick out in jaunty cones like a 1950s sex-bomb and the underwire dug into my chest. Clothes can be armour, yet in this case had depleted my self-preservation. I stood quite still, thinking only of what might happen next. I was against a wall in an alleyway at midnight, with no-one around except the man who was groping me. Finally I reacted, though it was not the reaction I would have guessed at my most objective self. Cowgirls get the blues, rough beasts slouch to be born and six foot one kick-boxing world travelling feminists scream like frightened cats with the shock of even minor violation. And certain men, I learned on my night out, chuckle at the distress they cause and then run away. After A Night Out The personal and public impacts of A Night Out proved to be cumulative over time and throughout retellings. When I read the piece at the Dhaka conference I was set to unleash the "transformative and efficacious potential" that autoethnography legendarily contains (Spry 712), though if my revelation achieved anything close to such a transformation, it was unclear. A female academic who had been chatting with me before my presentation, left the room directly after it. The students, mainly female undergraduates, had no questions to ask about any aspect of my paper. Whatever reactions my audience felt, if any, were not discussed. After my presentation, the male convenor privately expressed his regret over my experience and related more horrific examples. Sexual harassment of women is prevalent in Bangladesh yet so too is the culture of blaming the victim and denying the crime (cf. Lodhi; Mudditt; Nadiya), an attitude reflected through the use of the term "Eve Teasing," which assigns the provocative role to the woman and normalises the aggressive or sexual actions of the perpetrator (Kabeer 149). The response of this liberal and thoughtful man to my revelation was the only one that was articulated. By this measurement, A Night Out had failed to make the desired impact. One of the greatest reasons for this was the tension between the personal motivation behind my revelation and the public impact I had optimistically expected. A Night Out omits the reactions of my community immediately after my assault, when I was chastised for walking alone at such at late hour and for failing to defend myself, particularly given my size. In my street, gossip spread that I had not been groped but mugged, a less lecherous so perhaps more acceptable offense. I read A Night Out partly to gain some retrospective acknowledgement of my experience and in my determination I defied the complexities of a conservative country…[in which] women do not live alone, do not have male friends, do not travel by themselves or smoke cigarettes publicly and most definitely [...] do not talk or write about sexual topics. In Dhaka these things matter and 'decent women' are supposed to play by the rules. (Deen 35) Although I observed this conservatism to varying degrees in Bangladesh, I know that when women play outside the rules, negotiating cultural norms becomes a process of "alliance and conflict" that requires sensitivity to practise (Akhter 22)—a sensitivity that is difficult to grasp. The career of Bangladeshi writer Taslima Nasrin illustrates this: credited with opening doors of feminist discussion "that had been shuttered by genteel conservatism, by niceness, by ignorance and denial" (Nadiya), Nasrin diminished this effect and alienated her audience through subsequent "shock tactics and sensationalism" (Deen 56). Although my revelation had also alienated my audience, it was not the impact I had hoped for. While Linda Park-Fuller celebrates autoethnographic performance as a "transgressive act—a revealing of what has been kept hidden, a speaking of what has been silenced" (26), the conference experience made me realise the significance of cultural context to the impact of revelation. I considered recasting A Night Out in a setting that was more intimate than academic, to an audience prepared for the content and united by achieving a specific outcome, where responses could be given privately if desired. I would also have to shift my role from defiant storyteller to one who welcomed all types of feedback. By posting A Night Out online as a Facebook note, I not only fulfilled the requirements above but made the story accessible to a large audience of men and women of diverse cultural backgrounds, including Bangladeshi. The written replies I received were easier to decipher than the faces after the conference presentation. Among the responses, some from people I did not know at all, many conveyed their appreciation for the description of Bangladesh. Others commented on the risk I took in walking down the road at night and suggested ways I could defend myself in future. I was told I was tough to write the account and was invited to share more of my experiences. One friend in Bangladesh shared my note with others and wrote to describe the reaction of a female friend of his who was "terribly shocked" by what I had written about my breasts, more than my attraction to Farad or the sexual assault itself. This anonymous respondent's "pure cultural shock", which my conference audience may also have felt, was better communicated through the Facebook retelling of A Night Out, although I am unable to interpret the silence of the other Bangladeshi women I sent the note to. While the responses I received indicated my revelation had made some impact in its online context, I could not help being especially touched when a male friend wrote, "And as a Bangladeshi I feel sorry for [your trouble]." It is one matter to write up a personal experience and another to have it make a public impact. As my first reading of A Night Out shows, autoethnographic revelation contains the potential to alienate as well as to create sympathy with an audience. Combined with the second, more private and accessible, distribution of A Night Out, this "Before" and "After" analysis shows the evolution of the revelation's impact on my audience as well as myself, over time and within different cultural contexts, in the academic, social and online arenas. Although my experience confirms the impact autoethnography can make as a form of cultural research, it can only be strengthened by continued attempts to seek a balance between the projections and inflections of culture, self and audience. It is not only in the telling but in the re-telling that personal revelations will gather and continue to give impact, which is why I now present A Night Out to a new audience in a new context and await your new responses.

The task of the unpaid reviewer in academic publishing has always been a taxing one. Although the notion is one of blind peer review, the selection of reviewers is far from random. Journals try to balance a prospective reviewer’s expertise with their availability, and with their track record of returning a useful review on time. Ideally, the reviewer should have a specific (reasonably expert) knowledge of the paper’s topic, but should also retain enough in common with the interested, but jargon-averse, academic reader to empathise with non-specialist journal subscribers. Reviewers should be able to judge the quality of the argument, of the writing, and of the contribution of the article to the field. It’s a tough ask, and now there is a further layer of concern: will the reviewer – having satisfied all the foregoing – be able to spot ‘self-plagiarism’? Self-plagiarism is a relatively new evil – at least, few people in the author’s circle appear aware of it. Googling the term results in some 8,000 hits (whereas plagiarism scores 3,150,000). At first blush, the usual interpretation of plagiarism – the pinching of some one else’s intellectual property without acknowledgement – seems to rule out the possibility of self-plagiarism. Surely, if the ideas and words are your own, a little judicious re-purposing is all grist to the mill? Indeed, most of the anti-plagiarism sites, for example: What is Plagiarism? (Georgetown University), don’t include the term at all. Instead, the site offers examples of five types of plagiarism, most of them familiar to seasoned markers of student work, which are sufficiently rigorous to include “the ‘apt phrase’”, defined as the lifting of a part sentence. Their comment on the example they give for ‘apt phrase’ plagiarism involves four words in an original paragraph: “This passage is almost entirely original, but the phrase ‘dissolved into a conglomeration’ is taken directly from Arendt [the example used for illustration]. Even though this is a short phrase, it must be footnoted. Only phrases that have truly become part of general usage can be used without citation.” Georgetown University, then, sees plagiarism predominantly as a matter of correct attribution of authorship. Most journals have a requirement that no work offered to them for review should previously have been published, and that concurrent submissions to multiple journals are not permitted. The issue here, it seems, is that a journal’s reputation is built upon the originality and usefulness of its contents. Journal editors like to feel that they are ‘advancing the field’ with each edition and they are building a readership that can count upon learning something new (or, at least, provocative) for each hour invested in consuming their journal. Where papers have appeared in other forms (based, for example, on a presentation recorded in conference proceedings) this may be acceptable to the journal, provided it is acknowledged, and experienced editors will often check that papers developed from conference presentations have not previously been posted on the web. If two journals in ignorance each accept and publish the same paper at the same time then that reflects very poorly on the academic who failed to deal honestly with the editors. The issue here is one of resources – the printed page, in particular, is expensive – and of the reviewers’ time. Given the unpaid and voluntary labour of reviewers, and the amount of time and energy that goes into deciding which papers to accept or reject, journals think very poorly of someone who ‘withdraws’ a paper after acceptance on the grounds that s/he has got a better offer/earlier publication elsewhere. Most journals would not welcome future papers from that author. If self-plagiarism were a simple matter of passing off published paper A as published paper B (say, by changing the title and offering it elsewhere), then it would be seen to be deceitful and perpetrators would receive little respect from their peers. But these extreme cases are not (generally) the kind of self-plagiarism against which authors are warned. So what is the authorship problem widely referred to as ‘self-plagiarism’? The SPlaT website (SPlaT) is happy to explain: Self-plagiarism occurs when an author reuses portions of their previous writings in subsequent research papers. Occasionally, the derived paper is simply a re-titled and reformatted version of the original one, but more frequently it is assembled from bits and pieces of previous work. … It is our belief that self-plagiarism is detrimental to scientific progress and bad for our academic community. Flooding conferences and journals with near-identical papers makes searching for information relevant to a particular topic harder than it has to be. It also rewards those authors who are able to break down their results into overlapping least-publishable-units over those who publish each result only once. Finally, whenever a self-plagiarised paper is allowed to be published, another, more deserving paper, is not. Among the more chilling examples of self-plagiarism identified by the developers of SPlaT is “cryptomnesia (reusing one’s own previously published text while unaware of its existence)” (SPlaT). The avoidance of cryptomnesia is one reason why authors are encouraged to use the SPlaT tool. Academic and journal reviewers are also regarded as potential users, and the software is designed to work in three modes – ‘reviewer’s workbench’, ‘author’ and ‘web spider’. It is indeed a crypromnesiac’s concern that the ‘apt phrase’ that came so creatively to the author in an earlier paper might appear again, unwittingly, in the guise of an original composition. However, the injunction to use SPlaT as a ‘reviewer’s workbench’ (where “SPlaT compares a paper under review to a record of the author’s previously published articles extracted from their web site and online article repositories” [SPlaT]) begs the question as to how a review may remain blind – in the sense of not identifying the author of the work to be reviewed – if the ‘workbench’ and/or ‘web spider’ modes of SPlaT are pressed into service. Might it be the case, notwithstanding the foregoing, that the problem of self-plagiarism is as authentic as ‘social anxiety disorder’ (SAD), incidences of which multiplied dramatically once a drug, Paxil, had been shown effective in treating it? In a Washington Post article (Vedantam), the journalist-author comments: “according to a marketing newsletter, media accounts of social anxiety rose from just 50 stories in 1997 and 1998 to more than 1 billion references in 1999 alone” and goes on to say, “The education and advertising campaigns have raised concerns that pharmaceutical companies, traditionally in the business of finding new drugs for existing disorders, are increasingly in the business of seeking new disorders for existing drugs”. Prior to the publicity about SAD, Paxil was an anti-depressant with sales languishing way behind Prozac and Zoloft. The identification (and treatment) of social anxiety disorder did wonders for its marketing. Could it be that self-plagiarism has only come into existence as a major concern for academia now that there is a tool for its detection? Social anxiety disorder may be an authentic scourge – as may self-plagiarism – and the fact that it has been publicised in concert with its cure (or detection) does not mean that the remedy serves no useful purpose. On the contrary, once a population of professionals is attuned to a new way of viewing symptoms and practices then valuable advances may result. However, such advances are only possible when the community concerned has had a chance to consider the matter and discuss the ramifications. At the present, we run the risk of allowing the designers of anti-self-plagiarism software to be the judges and the jury of this new way to commit academic crime. One way to avoid charges of self-plagiarism is self-citation. Leaving aside crytomnesia, it is perfectly possible to cite the already-published reference when an author is aware of reusing a previously-published phrase or idea. Unfortunately, this remedy is also generally frowned upon in many academic circles. The practice undermines the principle of blind peer review – since the identity of the author soon becomes clear in such repeated instances – while readers may become irritated, suspecting that self-citation is a clumsy ruse to improve the citation index ratings of the originally-published article. The issue is of concern to more than journal editors: it also relates to text- and reference-book editors and publishers. One ‘for instance’ was discussed a year ago by the World Association of Medical Editors (WAME) who conducted a hypothetical on “self-plagiarism of textbook chapters” and threw the discussion open to the members’ list. The initial self-plagiarism case-study situation was complicated by the supposition that Author A (of Book A) had self-plagiarised a previously-published chapter which had been jointly authored by Author A and Author B (Book B). Notwithstanding this complication, the WAME Ethics Committee addressed themselves to four questions: Is [Does] reuse of a person’s writings in another textbook, but authored by the same person, meet the definition of plagiarism? If so, what degree of identical components needs to be present for this definition to be met? Is it appropriate for authors to write for different textbooks in the same field? If so, can they write on the same topic? If not, what are the potential infringements on the author’s rights to pursue their career/income? Should the editors of these textbooks agree to exclude authors that write for one another’s textbooks? Or is that unfair restraint of trade? For example, if all four textbooks were to agree to limit or completely avoid any overlap among authors, it could effectively deny entry of another textbook into that market. For book A, the author had a co-author. Since this shared work was used for book B, what is the author’s responsibility to the original co-author? (WAME) These are good questions and they are the kinds of questions we should be asking ourselves about self-plagiarism in our own ‘media and culture’ academic circles. In particular, in the case of textbooks, it is precisely because an author has a standing in the field, and has published on equivalent matters, that editors seek them out and ask them to contribute chapters. Whilst all reputable writers would expect to originate a new chapter according to the specific brief given, it is possible (some might even say likely) that there is an overlap in approach and phraseology. In the case of Books A and B, the overlap stretched the bounds of coincidence in that: “One table is essentially identical, although other tables in the two chapters are different. In addition, there are some passages that contain identical phrases. Most of these appear to have been reworded, but many identifiable words and phrases are identical between the two chapters. There are also areas where the text is completely different” (WAME). However, this hypothetical case is clearly not a situation where the same authorial product was disguised with a new title. Although the whole debate is worth reading, the general consensus of the Ethics Committee was along the lines of (specifically citing one response): I do not see a problem with the author reusing his own material to write a chapter in another textbook (readers of textbooks as opposed to research articles are not expecting originality). The problem is that he should have done this with the concurrence of the two editors and if he signed over his copyright the permission of publisher of textbook A. He should of course also have consulted with his co-author. I think the editors should inform the publishers and his employer of the facts and let them decide what course of action to take. (WAME) The references to re-using the material transparently, and the editors of the textbooks informing the author’s employer, are a constant refrain from a number of contributors to the discussion. Some WAME list discussants offer defences to the charge of self-plagiarism: “the main problem here is not whether the same, or very similar, information can or should be published in more than one place” commented Frank Davidoff, “that sort of thing is done all the time, and can serve important functions. After all, different people read different textbooks, and if it’s important for the information to get out there, why shouldn’t it be made as widely available as possible?” Andrew Herxheimer thought the readers’ perspective had not been given sufficient consideration: “If I were keenly interested in the contents of the chapter in textbook B, I might well wish to know how they had developed, and to look at earlier versions of the material, and to understand why the contents and emphases etc had changed in the way they had.” “The choice of an author for a review monograph or textbook chapter is based always on perusal of the existing reviews and chapters, hoping that the new publication can contain something just as good” argued Rick Nelson, going on to say, “that obligates the author to produce something as similar to his previous publication as possible, and yet different – an impossible task even if such writing were a priority endeavor, which it never is.” (WAME). Irving Hexham, of the Department of Religious Studies, University of Calgary, appears to have been substantially ahead of the game in discussing self-plagiarism in the 1990s. His consideration of the issue is generally more sympathetic than SPlaT’s, or WAME’s. For example, “Self-plagiarism must be distinguished from the recycling of one’s work that to a greater or lesser extent everyone does legitimately”, and: Academics are expected to republish revised versions of their Ph.D. thesis. They also often develop different aspects of an argument in several papers that require the repetition of certain key passages. This is not self-plagiarism if the complete work develops new insights. It is self-plagiarism if the argument, examples, evidence, and conclusion remain the same in two works that only differ in their appearance. (Hexham) It appears that Hexham and SPlaT have very different ideas of what constitutes self-plagiarism. Their different perspectives may be influenced by disciplinary perspectives and wider contexts – journal article or textbook chapter, a cannibalised conference paper or thesis – and by whether or not they have authored software to catch the offending behaviour. At least one Australian academic (not in M/C – Media and Culture) has been asked by their University to justify their publications against a charge of self-plagiarism, however, which is how the topic has become visible and why the need for debate has become urgent. Incidentally, the opening sentence of the opening paragraph to the Introduction of the paper on “Splat: A System for Self-Plagiarism Detection” is almost identical to the Abstract for a paper published two years later as “Self-Plagiarism in Computer Science”, viz: “We are all too aware of the ravages of scientific misconduct in the academic community. Students submit assignments inherited from the [sic] their friends who took the course the year before, on-line paper-mills allow students to browse for term papers on popular topics, and occasionally researchers are found out when falsifying data or publishing the work of others as their own.” (Collburg et al.) “We are all too aware of the ravages of misconduct in the academic community. Students submit assignments inherited from their friends, online papermills provide term papers on popular topics, and occasionally researchers are found falsifying data or publishing the work of others as their own.” (Collburg & Kubourov) Further, in these two papers there is a difference in authorship line-up, as with the WAME example… So what of the reviewers in all this? The Journal of Optical Networking, published by the Optical Society of America, comments that “self-plagiarism causes duplicate papers in the scientific literature, violates copyright agreements, and unduly burdens reviewers, editors, and the scientific publishing enterprise.” (JON). In an environment of blind peer review, where the reviewer does not know the author’s identity and is not in a position to check the body of their published work, the acid test becomes whether (in the reviewer’s opinion) the article advances the debate by offering something new. The submission should also repay the time and effort expended in reading and considering the contents. Other than that, issues of in/valid repurposing, repackaging, recycling and redeveloping arguments and findings require debate and determination at a discipline-wide level, rather than at the coalface of reviewers’ practice.
