Is it distinctively wrong to simulate doing wrong?

This paper is concerned with whether there is a moral difference between simulating wrongdoing and consuming non-simulatory representations of wrongdoing. I argue that simulating wrongdoing is (as such) a pro tanto wrong whose wrongness does not tarnish other cases of consuming representations of wrongdoing. While simulating wrongdoing (as such) constitutes a disrespectful act, consuming representations of wrongdoing (as such) does not. I aim to motivate this view in part by bringing a number of intuitive moral judgements into reflective equilibrium, and in part by describing the case of a character that I call The Devious Super Geek who simulates wrong to particular people that he knows personally. I build bridging cases from the case of the Devious Super Geek to capture games in which one simulates wrong to imaginary members of extant, morally salient categories. The surprising conclusions that we are led to include not just that simulated wrongdoing is pro tanto wrong, but that simulated Just killing is pro tanto wrong, and also that the simulated killing of zombies and aliens is also pro tanto wrong. Finally, I describe how I propose to handle some potential objections and attempt to weigh the pro tanto wrong identified in the paper against some countervailing considerations in some all things considered judgements.

We are in it together: Communitarianism and the performance-innovation relationship✰

The relationship between firm performance and innovation behavior has been widely studied, yet theoretical and empirical findings still widely diverge. We investigate this inconsistency through the lens of informal institutions, specifically communitarianism, the degee to which group goals are considered more important than individual goals. We do this through an analysis of a firm-level dataset covering 31,860 firms across 56 countries. We find evidence for a ‘cushion effect’, where firms in highly communitarian settings benefit from informal insurance in order to engage in innovation activity when their performance is below their aspirational value. Firms experiencing performance above aspirational value are also more likely to engage in innovation activity in highly communitarian settings due to a ‘pay-it-forward’ mechanism, using innovation activities to contribute to community challenges. Both effects are conditional on firms being sufficiently embedded in their direct business environment. We discuss the direct and wider implications for the literature on performance-innovation behavior and provide guidance for policy makers and practitioners.     

Is it time for robot rights? Moral status in artificial entities

Some authors have recently suggested that it is time to consider rights for robots. These suggestions are based on the claim that the question of robot rights should not depend on a standard set of conditions for ‘moral status’; but instead, the question is to be framed in a new way, by rejecting the is/ought distinction, making a relational turn, or assuming a methodological behaviourism. We try to clarify these suggestions and to show their highly problematic consequences. While we find the suggestions ultimately unmotivated, the discussion shows that our epistemic condition with respect to the moral status of others does raise problems, and that the human tendency to empathise with things that do not have moral status should be taken seriously—we suggest that it produces a “derived moral status”. Finally, it turns out that there is typically no individual in real AI that could even be said to be the bearer of moral status. Overall, there is no reason to think that robot rights are an issue now.

     

What is a genetic test, and why does it matter?

How the term ‘genetic test’ is defined, matters for social policy. The past few years have witnessed many efforts to enact legal barriers specifically against genetic discrimination. To the extent that information derived from genetic tests receives special protection, both enthusiasts for genetic medicine and those who stress its perils have an incentive to adopt a broad interpretation of genetic testing. However, the consequences have not always been those anticpated.     

Whose story is it anyway? Automatic extraction of accounts from news articles

Narratives are comprised of stories that provide insight into social processes. To facilitate the analysis of narratives in a more efficient manner, natural language processing (NLP) methods have been employed in order to automatically extract information from textual sources, e.g., newspaper articles. Existing work on automatic narrative extraction, however, has ignored the nested character of narratives. In this work, we argue that a narrative may contain multiple accounts given by different actors. Each individual account provides insight into the beliefs and desires underpinning an actor’s actions. We present a pipeline for automatically extracting accounts, consisting of NLP methods for: (1) named entity recognition, (2) event extraction, and (3) attribution extraction. Machine learning-based models for named entity recognition were trained based on a state-of-the-art neural network architecture for sequence labelling. For event extraction, we developed a hybrid approach combining the use of semantic role labelling tools, the FrameNet repository of semantic frames, and a lexicon of event nouns. Meanwhile, attribution extraction was addressed with the aid of a dependency parser and Levin’s verb classes. To facilitate the development and evaluation of these methods, we constructed a new corpus of news articles, in which named entities, events and attributions have been manually marked up following a novel annotation scheme that covers over 20 event types relating to socio-economic phenomena. Evaluation results show that relative to a baseline method underpinned solely by semantic role labelling tools, our event extraction approach optimises recall by 12.22–14.20 percentage points (reaching as high as 92.60% on one data set). Meanwhile, the use of Levin’s verb classes in attribution extraction obtains optimal performance in terms of F-score, outperforming a baseline method by 7.64–11.96 percentage points. Our proposed approach was applied on news articles focused on industrial regeneration cases. This facilitated the generation of accounts of events that are attributed to specific actors.     

Gender diversity in the management field: Does it matter for research outcomes?

This study examines the relationship between gender diversity and research outcomes. Existing research on the topic primarily focuses on how team gender diversity influences scholarly productivity in terms of citations and publication rates. Far less attention has been devoted to the question of how the intellectual contents of research disciplines change as they become more gender diverse. Drawing on a global sample of more than 25,000 management papers, we use natural language processing techniques, correspondence analysis and regression models to illuminate impact-, content- and status-related dimensions of gender diversity in management research. In regression models adjusting for geographical setting, institutional prestige and collaboration patterns, we find no discernable effects of team gender diversity on per-paper scientific impact. In contrast, our analyses converge to yield a broadly consistent pattern of gender-related variations in research focus: women are well-represented in social- and human-centered areas of management, while men comprise the vast majority in areas addressing more technical and operational aspects. Our findings corroborate recent sociological research suggesting that cultural norms and expectations are channeling women and men towards different areas of work and study. We argue that the broadened repertoire of perspectives, values and questions resulting from gender diversity may render management research more responsive to the full gamut of societal needs and expectations.     

Genes and speciation: is it time to abandon the biological species concept?

The biological species concept (BSC) is the cornerstone of neo-Darwinian thinking. In BSC, species do not exchange genes either during or after speciation. However, as gene flow during speciation is increasingly being reported in a substantial literature, it seems time to reassess the revered, but often doubted, BSC. Contrary to the common perception, BSC should expect substantial gene flow at the onset of speciation, not least because geographical isolation develops gradually. Although BSC does not stipulate how speciation begins, it does require a sustained period of isolation for speciation to complete its course. Evidence against BSC must demonstrate that the observed gene flow does not merely occur at the onset of speciation but continues until its completion. Importantly, recent genomic analyses cannot reject this more realistic version of BSC, although future analyses may still prove it wrong. The ultimate acceptance or rejection of BSC is not merely about a historical debate; rather, it is about the fundamental nature of species – are species (and, hence, divergent adaptations) driven by a relatively small number of genes, or by thousands of them? Many levels of biology, ranging from taxonomy to biodiversity, depend on this resolution.     

Taylor's Q1 “Visceral” level of information need: What is it?

Taylor (1968) dramatically stated that information seekers/searchers do not use their real Q1-level of information need when formulating their query to the system. Instead, they use a compromised Q4-level form of their need. The article directly confronts what Taylor's (1968) Q1-level information need is–the “actual” or “real” information need of the searcher. The article conceptually and operationally defines what Taylor's Q1-level of information need is using Belkin's (1980) ASK concept as a basis for designing a system intervention that shifts the searcher from representing the Q4-level compromised form of the need in her query to representing instead her Q1-level real information need. The article describes the Q1 Actualizing Intervention Model, which can be built into a system capable of actualizing the uncertainty distribution of the searcher's belief ASK so that information search is directed by the searcher's real Q1-level information need. The objective of the Q1 Actualizing Intervention Model is to enable in our Knowledge Age the introduction of intervention IR systems that are organic and human-centric, designed to initiate organic knowledge production processes in the searcher.     

Catching up with the market leader: Does it pay to rapidly imitate its innovations?

In this study we attempt to shed more light on the relationship between speed of new technology imitation and the sales performance of the imitator compared to the innovator, with a particular focus on the performance outcomes resulting from the rapid imitation of technologies introduced by the market leader. Using data on handset technologies mounted on more than 600 devices introduced to the UK market by 14 mobile phone vendors operating from 1997 to 2008, we study hundreds of imitative actions to test hypotheses on the extent to which an imitator can catch up (i.e., reduce the market share gap) with the market leader by rapidly imitating its innovations. First, we show that gaining advantage by rapidly imitating a technology pioneer is contingent on whether the pioneer is the market leader or a non-leader rival. Second, we find that the risks of rapid imitation of the market leader's technologies are mitigated when industry clockspeed is high, i.e., during a period of fast innovation and imitation cycles in an industry, resulting in rapid variations in product design. Third, we observe that the degree of competitive responsiveness of the technology pioneer when its innovations are imitated represents an important mechanism that can explain why speed of imitation may affect how an imitator can improve its market share gains relative to the pioneer. This paper advances competitive dynamics and imitation as predictive theories of how rapid imitators might catch up with market leaders in technology-intensive industries.
