This article is the first in a series that looks at the technological transformation of Des Moines Public Schools (DMPS). It concentrates on the costs, some financial but mostly human and organizational, that are emerging as the district begins to implement its plans for dramatically increasing computer technology use. The conclusion reached here is that not only ave the costs been greatly underestimated, they may even force a gradual shift of control over the learning environment.

In this groundbreaking new study, Lowell Nissen explores the use of teleological language in the study of subjects such as behaviorism, negative feedback, and natural selection. He argues that all existing analyses fail to explain how teleological language can be used legitimately, and provides his own analysis in terms of intentionality.

We examine the influence of word choices on mathematical practice, i.e. in developing definitions, theorems, and proofs. As a case study, we consider Euclid’s and Euler’s word choices in their influential developments of geometry and, in particular, their use of the term ‘polyhedron’. Then, jumping to the twentieth century, we look at word choices surrounding the use of the term ‘polyhedron’ in the work of Coxeter and of Grünbaum. We also consider a recent and explicit conflict of approach between Grünbaum (...) and Shephard on the one hand and that of Hilton and Pedersen on the other, elucidating that the conflict was engendered by disagreement over the proper conceptualization, and so also the appropriate word choices, in the study of polyhedra.

Innovation in medieval studies is the creative ability to go back to sources. Digging, exploring, and connecting material pieces of evidence, facts, and individuals uncover new knowledge. One of the most significant sources for the medieval textual production is the university. Understanding the writings stemming from different faculties of medieval universities requires skills, curiosity, and tools. Among such instruments, the statutes of universities help researchers not only to decipher the organization of the academic institutions and interpret the rules that apply (...) to scholars and to their professors, but also to decode how and why texts were produced. The faculty of theology represents the highest level where education led during the Middle Ages and delivers the highest degree such as the master in theology. All over Europe, such faculties become the impetus that drives the intelligentsia to produce a textual heritage that today generates inspiration for magisterial carriers. Among them, Professor Maarten Hoenen is one to praise today. Taking as a point of departure a recent publication of Maarten Hoenen, 1 I will propose to investigate the relation between the statute of universities and of intellectual practices within medieval academia-more precisely, how a researcher should dig for complementary sources when the main documentation depicting an intellectual practice, such as the protestatio and gratiarum actio, is missing. I do not intend to be exhaustive, but simply to focus on how we should understand these two actions, protestatio and gratiarum actio, in connection with the Sentences commentaries. 2 The paradox is that we have traces of these two practices in the surviving manuscripts stemming from the university, but we do not always have a description of these actions in their statutes. Protestatio represents an oath that bachelors take at the beginning of an academic exercise, and the gratiarum actio is the final paragraph that closes the same exercise by thanks addressed to the public. The span of time I will focus on is between the fourteenth and fifteenth centuries, since this is the period from which some testimonies survived that today help to better clarify how these actions were performed in medieval academia. It is also the period of naissance of the new faculties of theology all around Europe, as it is the case with Bologna, Vienna, Cracow, or Prague. They all embraced the model disseminated in Paris and Oxford on reading on the Sentences of Peter Lombard to obtain the degree of doctor in theology, and they contribute to building tradition, and therefore to produce sources for us today.

This text, commissioned by the OSUN Global Observatory of Academic Freedom, discusses how the concept of academic freedom is codified in Colombian Law and regulations of public and private higher education institutions. It also explores common conceptions of academic freedom among Colombian scholars, as well as commonly observed threats to it.

There are compelling medical, ethical, and legal arguments that support mandating use of a central institutional review board for the review of clinical trials performed at multiple institutional sites. Progress against serious diseases depends on this.

Ethical leadership matters in the context of organizational change due to the need for followers to trust the integrity of their leaders. Yet, there have been no studies investigating ethical leadership and organizational change. To fill this gap, we introduce a model of the moderating role of involvement in change. Organizational change and involvement in change are proposed as context-level moderators in the relationships of ethical leadership and work-related attitudes and performance. We employ a sample of 199 supervisor–subordinate pairs from (...) a wide variety of organizations. Results support a three-way interaction (ethical leadership, organizational change, and involvement in change) for performance and OCBs. Our results have important implications for organizational change since ethical leadership appears to complement follower involvement when change is happening. (shrink)

Through cultural transmission, repeated learning by new individuals transforms cultural information, which tends to become increasingly compressible . Existing diffusion chain studies include in their design two processes that could be responsible for this tendency: learning and reproducing . This paper manipulates the presence of learning in a simple iterated drawing design experiment. We find that learning seems to be the causal factor behind the increase in compressibility observed in the transmitted information, while reproducing is a source of random heritable (...) innovations. Only a theory invoking these two aspects of cultural learning will be able to explain human culture's fundamental balance between stability and innovation. (shrink)

As a neonatal neurologist, I serve families facing tragic decisions in which they must balance trade-offs between death and life with profound disability. I often find myself in complex discussions about future outcome, in which families sort through in real-time what information they value most in making such a choice. Will he laugh? Will he be in pain? Will he know how much he’s loved? In this month’s feature article, Brick et al share the results of an online survey aimed (...) at assessing public views on when a life is not worth living, in an effort to inform ongoing legal and clinical debates about withdrawal of life-sustaining treatment for children. These findings raise important questions about how we define and measure outcomes that matter to parents as they make these tragic decisions. It is challenging to interpret these findings in the absence of context of how decision-making for infants occurs in real-time. The nature of this study and its objective required that cases be substantially simplified. As the authors acknowledge, the prognoses and function of the children involved in these cases were often deeply contested. Prognostic uncertainty is common for children with significant …. (shrink)

This paper examines folk theories of algorithmic recommendations on Spotify in order to make visible the cultural specificities of data assemblages in the global South. The study was conducted in Costa Rica and draws on triangulated data from 30 interviews, 4 focus groups with 22 users, and the study of “rich pictures” made by individuals to graphically represent their understanding of algorithmic recommendations. We found two main folk theories: one that personifies Spotify and another one that envisions it as a (...) system full of resources. Whereas the first theory emphasizes local conceptions of social relations to make sense of algorithms, the second one stresses the role of algorithms in providing a global experience of music and technology. We analyze why people espouse either one of these theories and how these theories provide users with resources to enact different modalities of power and resistance in relation to recommendation algorithms. We argue that folk theories thus offer a productive way to broaden understanding of what agency means in relation to algorithms. (shrink)

Despite the recent advances in information and communication technology that have increased our ability to store and circulate information, the task of ensuring that the right sorts of information gets to the right sorts of people remains. We argue that the many efforts underway to develop efficient means for sharing information across healthcare systems and organizations would benefit from a careful analysis of human action in healthcare organizations. This in turn requires that the management of information and knowledge within healthcare (...) organizations be combined with models of resources and processes of patient care that are based on a general ontology of social interaction. The Health Level 7 (HL7) is one of several ANSI-accredited Standards Developing Organizations operating in the healthcare arena. HL7 has advanced a widely used messaging standard that enables healthcare applications to exchange clinical and administrative data in digital form. HL7 focuses on the interface requirements of the entire healthcare system and not exclusively on the requirements of one area of healthcare such as pharmacy, medical devices, imaging or insurance transactions. This has inspired the development of a powerful abstract model of patient care called the Reference Information Model (RIM). The present paper begins with an overview of the core classes of the HL7 (Version 3) RIM and a brief discussion of its “actcentered” view of healthcare. Central to this account is what is called the life cycle of events. A clinical action may progress from defined, through planned and ordered, to executed. These modalities of an action are represented as the mood of the act. We then outline the basis of an ontology of organizations, starting from the theory of speech Acts, and apply this ontology to the HL7 RIM. Special attention is given to the sorts of preconditions that must be satisfied for the successful performance of a speech act and to the sorts of entities to which speech acts give rise (e.g. obligations, claims, commitments, etc.). Finally we draw conclusions for the efficient communication and management of medical information and knowledge within and between healthcare organizations, paying special attention to the role that medical documents play in such organizations.

Blockchain is an open digital ledger technology that has the capability of significantly altering the way that people operations operate in organizations. This research takes a first step in proposing several ways in which the blockchain technology can be used to improve current organizational practices, while also considering the ethical implications. Specifically, the paper examines the role that blockchain technology plays in three primary areas of people operations: entry to the organization, intraorganizational processes, and exit. In each section, the paper (...) reviews the ethical implications from the lenses of virtue ethics, utilitarianism, deontology and contractarianism. The paper concludes that in whole the implementation of blockchain technology in people operations processes can create a more ethical work environment. However, careful implementation is necessary and requires extensive examination of ethical implications in advance. (shrink)

There is growing interest in the role of new urban agriculture models to increase local food production capacity in cities of the Global North. Urban rooftop greenhouses and hydroponics are examples of such models receiving increasing attention as a technological approach to year-round local food production in cities. Yet, little research has addressed the unintended consequences of new modes of urban farming and food distribution, such as increased competition with existing peri-urban and rural farmers. We examine how small-scale farmers perceive (...) and have responded to a recently established rooftop greenhouse and online marketplace enterprise in Montréal, Canada. Drawing on interviews with key informants and small-scale farmers, we find that peri-urban and rural producers have been affected in three key ways that represent tensions, adaptations, and synergies arising from this new urban agriculture and food distribution enterprise. First, many farmers are concerned about increased competition and value conflation with the ideals of community supported agriculture and organic farming. Second, some farmers have adapted by developing novel marketing strategies and working with local bridge organizations to collectively market their produce to urban consumers. Third, a few farmers have decided to wholesale their produce to this new enterprise, allowing them to specialize production and avoid marketing their produce directly to urban consumers. Our study suggests that the emergence of a new form of alternative food network in Montréal has created both positive and negative disruptions for existing small-scale producers. Advocates for the expansion of new urban food production and distribution models should therefore give greater consideration to the effects on other actors in the local food system. (shrink)

Despite the recent advances in information and communication technology that have increased our ability to store and circulate information, the task remains of ensuring that the right sorts of information reach the right sorts of people. In what follows we defend the thesis that efforts to develop efficient means for sharing information across healthcare systems and organizations would benefit from a careful analysis of human action in healthcare organizations, and that the communication of healthcare information and knowledge needs to rest (...) on a sound ontology of social interaction. We illustrate this thesis in relation to the HL7 RIM, which is one centrally important tool for communication in the healthcare domain. (shrink)

Given that mitigating climate change is a large-scale global issue, what obligations do individuals have to lower their personal carbon emissions? I survey recent suggestions by Walter Sinnott-Armstrong and Dale Jamieson and offer models for thinking about their respective approaches. I then present a third model based on the notion of structural violence. While the three models are not mutually incompatible, each one suggests a different focus for mitigating climate change. In the end, I agree with Sinnott-Armstrong that people have (...) limited moral obligations to directly lower personal emissions, but I offer different reasons for this conclusion, namely that the structural arrangements of our lives place a limit on how much individuals can restrict their own emissions. Thus, individuals should focus their efforts on changing the systems instead (e.g., the design of cities, laws and regulation, etc.), which will lead to lower emissions on a larger scale. (shrink)

We investigate the emergence of iconicity, specifically a bouba-kiki effect in miniature artificial languages under different functional constraints: when the languages are reproduced and when they are used communicatively. We ran transmission chains of participant dyads who played an interactive communicative game and individual participants who played a matched learning game. An analysis of the languages over six generations in an iterated learning experiment revealed that in the Communication condition, but not in the Reproduction condition, words for spiky shapes tend (...) to be rated by naive judges as more spiky than the words for round shapes. This suggests that iconicity may not only be the outcome of innovations introduced by individuals, but, crucially, the result of interlocutor negotiation of new communicative conventions. We interpret our results as an illustration of cultural evolution by random mutation and selection. (shrink)

This essay examines how early moderns used birth horoscopes (genitures) to assess the compatibility of prospective spouses before marriage. Astrologers could probe the horoscope of an individual to investigate his or her present and future physical and moral qualities or compare charts to reveal the personal compatibility of a couple and help establish the best time to consummate their marriage. These practices aimed at ensuring a fruitful marriage and the harmony and happiness of the couple and their families. Focusing on (...) a few key examples, the essay outlines both the astrological theories and the social politics that propelled astrological matching, suggesting that its appeal lay in the promise of informed choice while also preserving free will. Finally, the author suggests ways in which astrological practices and the use of vast amounts of astronomical data share affinities with data-driven matching in our own time. (shrink)

Significant scientific and technological advances in intensive care have been made. However, patients in the intensive care unit may experience discomfort, loss of control, and surreal experiences. This has generated relevant debates about how to humanize the intensive care units and whether humanization is necessary at all. This paper aimed to explore how humanizing intensive care is described in the literature. A scoping review was performed. Studies published between 01.01.1999 and 02.03.2020 were identified in the CINAHL, Embase, PubMed, and Scopus (...) databases. After removing 185 duplicates, 363 papers were screened by title and abstract. Full-text screening of 116 papers led to the inclusion of 68 papers in the review based on the inclusion criteria; these papers mentioned humanizing or dehumanizing intensive care in the title or abstract. Humanizing care was defined as holistic care, as a general attitude of professionals toward patients and relatives and an organizational ideal encompassing all subjects of the healthcare system. Technology was considered an integral component of intensive care that must be balanced with caring for the patient as a whole and autonomous person. This holistic view of patients and relatives could ameliorate the negative effects of technology. There were geographical differences and the large number of studies from Spain and Brazil reflect the growing interest in humanizing intensive care in these particular countries. In conclusion, a more holistic approach with a greater emphasis on the individual patient, relatives, and social context is the foundation for humanizing intensive care, as reflected in the attitudes of nurses and other healthcare professionals. Demands for mastering technology may dominate nurses’ attention toward patients and relatives; therefore, humanized intensive care requires a holistic attitude from health professionals and organizations toward patients and relatives. Healthcare organizations, society, and regulatory frameworks demanding humanized intensive care may enforce humanized intensive care. (shrink)

We examine change across U.S. cohorts born between 1920 and 2000 in their probability of having had sex with same-sex partners in the last year and since age 18. Using data from the 1988–2018 General Social Surveys, we explore how trends differ by gender, race, and class background. We find steep increases across birth cohorts in the proportion of women who have had sex with both men and women since age 18, whereas increases for men are less steep. We suggest (...) that the trends reflect an increasingly accepting social climate, and that women’s steeper trend is rooted in a long-term asymmetry in gender change, in which nonconformity to gender norms is more acceptable for women than men. We also find evidence that, among men, the increase in having had sex with both men and women was steeper for black than for white men, and for men of lower socioeconomic status; we speculate that the rise of mass incarceration among less privileged men may have influenced this trend.

In the paper “Categoricity in abstract elementary classes with no maximal models”, we address gaps in Saharon Shelah and Andrés Villavecesʼ proof in [4] of the uniqueness of limit models of cardinality μ in λ-categorical abstract elementary classes with no maximal models, where λ is some cardinal larger than μ. Both [4] and [5] employ set theoretic assumptions, namely GCH and Φμ+μ+).Recently, Tapani Hyttinen pointed out a problem in an early draft of [3] to Villaveces. This problem stems from the (...) proof in Shelah and Villavecesʼ [4] that reduced towers are continuous. Residues of this problem also infect the proof of Proposition II.7.2 in VanDieren [5]. We respond to the issues in Shelah and Villaveces [4] and VanDieren [5] with alternative proofs under the strengthened assumption that the abstract elementary class is categorical in μ+. (shrink)
