We analyze the social and private learning at the symmetric equilibria of a queueing game with strategic experimentation. An infinite sequence of agents arrive at a server that processes them at an unknown rate. The number of agents served at each date is either a geometric random variable in the good state or zero in the bad state. The queue lengthens with each new arrival and shortens if the agents are served or choose to quit the queue. Agents can observe only the evolution of the queue after they arrive; they, therefore, solve a strategic experimentation problem when deciding how long to wait to learn about the probability of service. The agents, in addition, benefit from an informational externality by observing the length of the queue and the actions of other agents. They also incur a negative payoff externality, as those at the front of the queue delay the service of those at the back. We solve for the long‐run equilibrium behavior of this queue and show there are typically mass exits from the queue, even if the server is in the good state.

The Impact

AbstractIntegrated economic models have become popular for assessing climate change. In this paper we show how these methods can be used to assess the impact of a discard ban in a fishery. We state that a discard ban can be understood as a confiscatory tax equivalent to a value-added tax. Under this framework, we show that a discard ban improves the sustainability of the fishery in the short run and increases economic welfare in the long run. In particular, we show that consumption, capital and wages show an initial decrease just after the implementation of the discard ban then recover after some periods to reach their steady-sate values, which are 16–20% higher than the initial values, depending on the valuation of the landed discards. The discard ban also improves biological variables, increasing landings by 14% and reducing discards by 29% on the initial figures. These patterns highlight the two channels through which discard bans affect a fishery: the tax channel, which shows that the confiscation of landed discards reduces the incentive to invest in the fishery; and the productivity channel, which increases the abundance of the stock. Thus, during the first few years after the implementation of a discard ban, the negative effect from the tax channel dominates the positive effect from the productivity channel, because the stock needs time to recover. Once stock abundance improves, the productivity channel dominates the tax channel and the economic variables rise above their initial levels. Our results also show that a landed discards valorisation policy is optimal from the social welfare point of view provided that incentives to increase discards are not created.

AbstractThere had been a long way to go before we felt comfortable about even discussing the issues revolving around the concept of ‘schizophrenia’, let alone reckoning on mere semantic revision. In this editorial, we aim to extend our discussion on the reasons behind the slow death of the concept of ‘schizophrenia’ and the benefits of changing the name and embracing a spectrum approach with an umbrella psychosis spectrum disorder (PSD) category (similar to autism spectrum disorder) that goes further than a mere semantic revision. We attempted to cover the topic of the renaming by providing five most pertinent points categorised under five domains: reasons, signals, challenges, promises and steps for the change. Admittedly, even a modest revision, such as classifying all psychotic disorder categories under an umbrella category of PSD, and abolishing the term schizophrenia requires careful deliberation and some effort in the beginning, but the revision is well worth the effort considering the benefits in the long run. Renaming a particular form of mental suffering should be accompanied by a broader debate of the entire diagnosis-evidence-based-practice (EBP)-symptom-reduction model as the normative factor driving the content and organisation of mental health services that may be detached from patients’ needs and reality, overlooks the trans-syndromal structure of mental difficulties, appraises the significance of the technical features over the relational and ritual components of care, and underestimates the lack of EBP group-to-individual generalisability. Individuals may make great strides in attaining well-being by accommodating to living with mental vulnerabilities through building resilience in the social and existential domains. Changing the name and the concept of ‘schizophrenia’, which goes beyond a mere semantic revision, may become the first step that allows catalysation of the process of modernising psychiatric science and services worldwide.

Working Out

Disfluency in spontaneous speech is currently a subject of study of specialists working in different fields of knowledge. Different external manifestations of disfluency (hesitation pauses, sound prolongations, pause fillers, articulatory perseverations and lexico-grammatical repetitions, self-corrections, breaks, nonverbal means of information transfer, etc.) are being investigated. They turn out to be a convenient tool for revealing and monitoring the peculiarities of cognitive processes with the help of explicit clearly registered signals occurring in speech under the influence of a number of extralinguistic factors such as the communicative situation, the type of speech (monologic or dialogic), the language of communication (L1 or L2), the emotional state of the speaker, the age, the social status, the diseases impairing speech and mental activity, and others. Further investigation of disfluency makes it possible to solve both a number of fundamental problems connected with modeling of cognitive coding and decoding speech processes and applied tasks connected with adoption of research findings in such fields as developmental pedagogy, psychology, medicine, foreign language training, translation, automatic recognition of speech signal, etc. Up to now, a sufficient number of empirical investigations have been carried out providing a basis for working out particular models which will make it possible, in the long run, to create the overall model of disfluency in spontaneous speech. Conferences and workshops undoubtedly play an important role in uniting the efforts of specialists in this sphere. One of them is the international workshop “Disfluency in Spontaneous Speech (DiSS)” that was first held in 1999. The current problems that were discussed by the participants of the workshop (production and perception speech models, age and clinical factors of disfluency, special difficulties in foreign speech production, including translation, speech technology) may be a useful reference point for researchers working on the issue.

The effectiveness of devolution policies through social forestry programs in village forest schemes is still being debated at regional, national, and international levels. It departs from the fact that the community has limited resources in managing forests in the long run (35 years). The background of this research is to measure the implementation of devolution policy in 10 granted village forest licenses in the sub-district of Batu Ampar, Kubu Raya District, and its relationship with deforestation rates. The study was conducted by survey method and data collection with literature studies and observations. Observation aims to measure the biophysical condition of the forest as well as the social and economic conditions of the community in the village. The data is processed and analyzed using spatial analysis and performance analysis. The results showed that the devolution policy through the issuance of 10 village forest licenses was proven to be able to improve performance in reducing deforestation, especially after one year of the village forest permits were granted. Keywords: devolution, social forestry, village forest, deforestation, performance AbstrakEfektifitas kebijakan devolusi melalui program perhutanan sosial skema hutan desa masih menjadi perdebatan di level regional, nasional, dan internasional.

Pierre Bourdieu’s Masculine Domination was published in English in 2001, three years after the appearance of the French version. In order to deconstruct in vivo the working of sociological paradigm-alchemy, a close reading of the Bourdieusian argument is offered. After summing up the main thesis of the book, Bourdieu’s statements will be intended to be questioned, according to which the school, the family, the state and the church would reproduce, in the long run, masculine domination. The paper will also seek to identify the methodological trick of the Bourdieusian vision on history, namely that, metaphorically speaking, he compares the streaming river to the riverside cliffs. It will be argued that when Bourdieu discusses ‘the constancy of habitus’, the ‘permanence in and through change’, or the ‘strength of the structure’, he extends his paradigm about the displacement of the social structure to the displacement of the men/women relationship. Hence, it will be suggested that, in opposition to Bourdieu’s thesis, masculine domination is not of universal validity but its structural weight and character have fundamentally changed in the long run, i.e. the masculine habitual centre gradually shifted from a social practice governed by the drives of physical violence to symbolic violence.

Malaysia as a country has grown quite a lot over the last two decades despite the political condition often troubled with allegations of corruption but speaking economically and in social context, it can be claimed that as a country, Malaysia has fared in a decent manner and it has been able to maintain stability which has helped to elevate the progress of the nation. The social structure of Malaysia is in such a manner where there is a broad distribution of multiple ethnicities and cultures that it has been able to maintain but in accordance to the latest Gender Development Index, as till 2017, Malaysia ranks 57th among the 189 countries (http://hdr.undp.org/en/composite/GDI) and is categorized as a country with “VERY HIGH HUMAN DEVELOPMENT”. The paper makes an attempt to analyze and evaluate the various factors that have direct and indirect implications in acting as factors to influence the presence of “glass ceiling” in the higher education sector with focus on women administration. The objective is to explore and identify the different reasons behind women having to struggle in a country that has such a commendable mark in the HDI where the ones leading are from generally characterized first world countries. The discussion would highlight ways as suggested and put forth by the respondents who have been exposed to “glass ceiling” in various aspects of their career from the different sources and their opinion as to how they were able to overcome and how the upcoming young generation, the women who are aspiring to join the workforce in the coming future can prepare themselves in a manner that would assist them to prepare themselves in ways that the effects and impacts of “glass ceiling” can be reduced and tackled. The role of the components from the society to have an active role in making the effects to be reduced is extremely crucial and has to be dealt with in a manner that can serve the society in the long run.

Social Surplus

Many people are worried about the fragmentation of labor markets, as firms replace employees with independent contractors. Another common worry is that low-skill work, and ultimately nearly all forms of work, will be replaced by robots as artificial intelligence advances. Labor market fragmentation is not a new phenomenon and can be addressed with stronger classification laws supplemented by antitrust enforcement. In fact, the gig economy has many attractive elements, and there is no reason to fear it as long as existing laws are enforced. Over the long run, artificial intelligence may replace much of the work currently performed by human beings. If it does, the appropriate response is not antitrust or employment regulation but policy that ensures the social surplus is fairly divided.

The Relationship

This Chapter advances two claims which are related and sustain each other. The first is that in the contemporary “post-Fordist” world, the coupling of imprisonment and production persists in a relationship, if not between “the prison” and “the factory” – as Dario Melossi and Massimo Pavarini wrote 40 years ago – rather between “the prison” and “subordination”, because what all the multiple forms of “labor” and “non-labor” have in common – and have in common with the origins of protoindustrial capitalism – is subordination. The second is that the traditional reading of the “Rusche and Kirchheimer hypothesis” on the relationship between economic cycles and imprisonment depends on the specific conjuncture and class composition of the capitalist social formation to which it is applied. One thing is economic development in the period of Fordist mass industry and another in the globalized and fragmented labor market of neo-liberalism. Often imprisonment promotes phases of capitalist development rather than crises and recessions. Furthermore, subordination and inequality are strictly linked and feed on each other. Inequality promotes subordination, by putting the squeeze on those who are at the bottom of the social hierarchy; but subordination at the same time promotes inequality, by making sure that those who occupy those bottom positions, stay there. One strong link in the chain of subordination to inequality is penality, because penality reinforces inequality by reaffirming subordination. Data about long-run empirical relationships between imprisonment rates and inequality measures for the US and Italy are discussed.

We analyze the optimal debt reduction problem in an uncertainty context. The social planner has a finite horizon and seeks to minimize the social costs associated with debt repayment by taking into account not only the short-run costs of the policy, but also the long-run costs associated with the outstanding level of debt. We characterize the optimal policy and the dynamics of the debt-to-GDP ratio, showing that it will decrease over time if economic policy is effective enough. We characterize how the evolution of the debt-to-GDP ratio depends on the main parameters and we present a simple calibration based on Greek data to illustrate the implications of our analysis in real-world setups.

Abstract. This article discusses the distinction between situated (i. e., temporary and limited) identification and deep-structure (i. e., enduring and multi-faceted) identification with organizations. Research in the social identity tradition suggests that managers can foster employees’ situated identification by emphasizing (a) organizational successes, (b) competition with other firms, (c) employees’ shared features, and (d) personal and organizational distinctiveness. Repeated exposure to these identity reinforcers can turn situated identification into deep-structure identification, especially when employees trust the organization and derive particularistic resources from it (e. g., recognition, information, status). This article concludes with the positive and negative consequences of deep-structure and situated identification for (a) the acceptance of organizational change, (b) reactions to threats to organizational status, and (c) temporary work relationships.
