An ideography is a general-purpose code made of pictures that do not encode language, which can be used autonomously – not just as a mnemonic prop – to encode information on a broad range of topics. Why are viable ideographies so hard to find? I contend that self-sufficient graphic codes need to be narrowly specialized. Writing systems are only an apparent exception: at their core, they are notations of a spoken language. Even if they also encode non-linguistic information, they are useless to someone who lacks linguistic competence in the encoded language or a related one. The versatility of writing is thus vicarious: writing borrows it from spoken language. Why is it so difficult to build a fully generalist graphic code? The most widespread answer points to a learnability problem. We possess specialized cognitive resources for learning spoken language, but lack them for graphic codes. I argue in favor of a different account: what is difficult about graphic codes is not so much learning or teaching them as getting every user to learn and teach the same code. This standardization problem does not affect spoken or signed languages as much. Those are based on cheap and transient signals, allowing for easy online repairing of miscommunication, and require face-to-face interactions where the advantages of common ground are maximized. Graphic codes lack these advantages, which makes them smaller in size and more specialized.
Chapter 9 begins with a review of the contribution of talk to maintaining homeostasis through “small talk” and other forms of “grooming,” both as a response to complex social structure and in facilitating social cooperation. It discusses the role of talk in forward projection of group-level representations, and the role of forward projection of a conversation topic in sustaining and managing conversations. It discusses the role of both physical constraints and social constraints such as politeness norms and facework in shaping the structure of conversation practices. It discusses the fine structure of conversation, in which the interpretations of utterances are confirmed or revised by subsequent utterances and the macro-structure of conversation (beginnings, turn-taking, topics, and closure).
Chapter 10 focuses on representatations and warranties made by parties in IP agreements, as well as liability-allocation mechanisms such as indemnification. The chapter begins by discussing warranties of title (Loew’s v. Wolff) and general “corporate” warranties, then addresses warranties relating to performance (including malicious computer code) and remedial procedures. Disclaimers, exclusions from liabilty for consequential and indirect damages, and limitations of liability are also addressed. the chapter next discusses IP indemnification clauses, including a detailed analysis of the drafting and negotiation of such clauses (So. Cal. Gas v. Syntellect). It concludes with a discussion of insurance requirements and clauses.
In 2019, the Museum of Black Civilizations was inaugurated by President Macky Sall. The concept for this museum had been launched by President Senghor during the First World Festival of Negro Arts in 1966. More than 50 years later, the museum finally opened its doors. Its timely opening made headlines across the world as it coincided with a global debate on the restitution to the countries of origin of objects illicitly acquired under colonial rule. Funded by the Republic of China, the Museum of Black Civilizations offered itself as a recipient for the restitution of 100 objects collected on Senegal’s territory. This chapter discusses the realization both of Senghor’s concept for a museum of Black Civilizations in the twenty-first century and of a project for the recuperation of African civilization. Through an analysis of its programme and exhibitions, the chapter examines how the museum decolonizes the concept of the museum by focusing on its exhibition of Abrahamic religions, as well as on the sabre of El Hadj Oumar Tall, an object that the Restitution Report advised should be a priority for return. Analysing the museum’s politics of restitution and repair, it frames the museum’s concept of Blackness as a technique to repair the legacies of race science.
The Introduction situates the book’s themes in three different debates. First, it situates the question of Senegal’s decolonization in a debate about non-national futures as they were imagined by Negritude and Pan-African thinkers at the time of decolonization. Although these non-national futures have now become unthinkable, this book demonstrates that they are remembered as futures past in Senegal’s colonial heritage sites. Second, it situates the interpretation of Senegal’s cultural heritage in a debate about the legacy of Léopold Sédar Senghor’s Negritude. Senegal’s politics of heritagization are indebted to the Negritude philosophy of Senegal’s first president, whose politics of heritage were aimed at the reclamation of African dignity and respect, promising liberation through recuperation. Hence, this book situates the reclamation of African heritage in a temporality of return and frames cultural heritage as a technique of repair. Third, it situates the reclamation of African heritage in debates about world heritage, arguing that Senghor’s archiving project and support for UNESCO’s World Heritage List constituted parallel heritage projects pointing towards the decolonization of world heritage. The book posits that decolonization as envisioned by UNESCO and Senghor is a project to repair the traumas of modernity.
Senegal features prominently on the UNESCO World Heritage List. As many of its cultural heritage sites are remnants of the French empire, how does an independent nation care for the heritage of colonialism? How does it reinterpret slave barracks, colonial museums, and monuments to empire to imagine its own national future? This book examines Senegal's decolonization of its cultural heritage. Revealing how Léopold Sédar Senghor's philosophy of Négritude inflects the interpretation of its colonial heritage, Ferdinand de Jong demonstrates how Senegal's reinterpretation of heritage sites enables it to overcome the legacies of the slave trade, colonialism, and empire. Remembering and reclaiming a Pan-African future, De Jong shows how World Heritage sites are conceived as the archive of an Afrotopia to come, and, in a move towards decolonization, how they repair colonial time.
This chapter traces the history of repair. Beginning with the earliest human tools, like hand axes and spears, repair techniques evolved to keep pace with technology. In industrial era, the introduction of interchangeable parts promised to make repair easier and more reliable than ever before. But over the course of the twentieth century, manufacturers realized that product durability often wasn’t in their economic self interest. So they found ways to induce consumption and discourage repair. As early as the 1920s, firms were exploring the strategies that would eventually become known as “planned obsolescence.” By the 1950s, those techniques were cornerstones of the consumer economy.
This chapter considers how the set of tools provided by consumer protection law can push back on repair restrictions. Consumer protection law is designed, in part, to ensure the accuracy of information in the marketplace. But even in absence of outright deception, it recognizes the need to prohibit unfair practices that take advantage of the natural information asymmetries that sellers enjoy. It also offers remedies when products fail to live up to minimal, baseline guarantees of quality. Although consumer protection cases rarely lead to dramatic, structural remedies, the law profoundly influences marketplace behavior and can improve the day-to-day experiences of consumers seeking repair.
This chapter considers three sets of concrete benefits that flow from repair. First, repair helps consumers save money by extending the lifespan of products and fostering secondary markets. Second, repair lessens the massive environmental burden of modern consumerism, from the extraction of natural resources to the eventual disposal of the devices we buy. Finally, repair helps us grow and flourish as people. Through repair, we become better informed about the world around us, develop analytical and problem-solving skills, exercise greater autonomy, and build stronger communities.
This chapter introduces the threats to product longevity and durability created by legal frameworks and product design decisions that shift power from consumers to device makers. In contrast to earlier generations of technology, today’s devices—from smartphones and headphones to medical and agricultural equipment—are designed to be replaced, not repaired.
This chapter outlines the sophisticated array of strategies and techniques that today’s device makers have developed to discourage and obstruct repair. Firms rely on product design, economic manipulation, and consumer persuasion to steer us away from repair and keep us buying new devices year after year. They use hardware and software design to erect practical barriers to repair. They charge unnecessarily high prices for repair or refuse to fix products at all. At the same time, they deny independent repair providers access to parts and tools necessary to meet consumer demand. And through subtle and explicit messaging, they discourage consumers from even attempting repairs.
This chapter describes how device makers try to leverage intellectual property (IP) rights to restrict repair and why those assertions are, as a general rule, inconsistent with a proper understanding of the law. IP—in the form of copyrights, patents, trademarks, and trade secrets—offers manufacturers an arsenal of weapons in the war on repair. From a practical perspective, IP law allows firms to credibly threaten to enjoin, silence, and ultimately bankrupt anyone with the audacity to repair a product without permission. That’s true despite the fact that IP claims against consumers and repair providers rest on questionable legal foundations.
This chapter considers the role antitrust law can play in safeguarding repair markets and, along with them, the interests of competitors and consumers. While IP law may grants device makers power over their products, antitrust and competition law are designed to impose limits on exclusionary behavior. As a result, they serve as potential bulwarks against tactics that would impede repair. Despite significant doctrinal and policy hurdles to enforcement, antitrust law can help discipline firms that attempt to capture markets for the repair of vehicles, electronics, and appliances that account for hundreds of billions of dollars in annual revenue.
This study aimed to analyse the effectiveness of using the bony sigmoid sinus plate for repair of meato-mastoid fistulae.
Method
A retrospective study of all cases between January 2013 and December 2019 at our secondary-tertiary centre was conducted. Inclusion criteria for study were: (1) cases with focal meato-mastoid fistulae and (2) focal meato-mastoid fistulae that were repaired by using bony sigmoid sinus plate using the bony sigmoid sinus plate technique. There were 13 cases that fulfilled these criteria.
Results
The outcome of the repair of meato-mastoid fistulae with bony sigmoid sinus plate was very encouraging. All 13 cases did well. Two patients had delayed epithelialisation at 9 and 12 months after surgery.
Conclusion
The technique of repairing meato-mastoid fistulae by using bony sigmoid sinus plate is simple, repeatable and provides effective physiological reconstruction of the posterior canal wall. Bony sigmoid sinus plate is easily and locally available in all cases undergoing cortical mastoidectomy. This plate of bone has a curvature, consistency and structure that match well with that of the posterior or superior canal wall. In addition, this technique is cost-effective with good patient compliance.
In recent decades, companies around the world have deployed an arsenal of tools - including IP law, hardware design, software restrictions, pricing strategies, and marketing messages - to prevent consumers from fixing the things they own. While this strategy has enriched companies almost beyond measure, it has taken billions of dollars out of the pockets of consumers and imposed massive environmental costs on the planet. In The Right to Repair, Aaron Perzanowski analyzes the history of repair to show how we've arrived at this moment, when a battle over repair is being waged - largely unnoticed - in courtrooms, legislatures, and administrative agencies. With deft, lucid prose, Perzanowski explains the opaque and complex legal landscape that surrounds the right to repair and shows readers how to fight back.
"This chapter considers the role of institutions in re-building trust and connection for families in exile. It introduces the evolutionary evidence that human beings are co-operative breeders and that, as a result, the need to belong and connect to communities or groups is central for human flourishing. It draws on reflections on the experiences of refugees, which are shaped by the destruction of human connectedness. In this context, the chapter explores the role of the institutions and service providers who come in contact with refugee people and families. It discusses the approaches systems create to re-build trust and connection in the post-trauma phase and argues that these approaches can indeed lead to the re-building and re-making of trust, but that they can also create a re-enacting and re-breaking of trust and connectedness. Thus, it is useful to explore frameworks and principles that may assist in shaping approaches so that relational repair, and not further rupture, can occur. In the final section, the chapter recommends therapeutic practices for practitioners to consider when doing the work of re-building trust for refugee families."
Pig intestinal epithelium undergoes a complete renewal every 2 to 3 days that is driven by intestinal stem cells (ISCs) located at the crypt base in their niche. Intestinal stem cells generate a pool of highly proliferative transit-amplifying cells, which either migrate up the villus and differentiate into enterocytes and secretory cells or migrate towards the base of the crypt where they differentiate into Paneth cells that secrete antimicrobial peptides. The balance between ISCs’ self-renewal and differentiation controls intestinal epithelial homeostasis; therefore, ISCs are essential for ensuring intestinal epithelial integrity. Detailed knowledge of these mechanisms in pig and other domestic species is very limited. Therefore, the aim of this work was to characterize ISC from birth to weaning. We analysed the duodenum, jejunum and colon of six piglets at birth, 6-day-old nursing piglets and 28-day-old weanlings, one week after weaning. We immunolocalized homeobox only protein+ (HOPX) and sex-determining region Y-box 9+ (SOX9) cells that identify quiescent and active ISC, respectively. The volume of ISCs was quantified with stereological methods and was compared to that of mitotic cells expressing proliferating cell nuclear antigen and apoptotic cells identified by the presence of cleaved caspase-3. Furthermore, we compared all these values with crypts and villi measurements and their ratio. Our results indicated that both quiescent and active ISCs are present in pig intestine from birth to weaning and are localized in the crypts of the small and large intestine. However, both markers were also observed along the villi and on the colon luminal epithelium, suggesting that at these stages, pig mucosa is still immature. Weaning induced a dramatic reduction of both HOPX+ and SOX9+ cells, but SOX9+ cells underwent a significantly greater reduction in the small intestine than in the colon. This suggests that the two ISC types are differentially regulated along the intestinal tracts. Overall, the pig ISC complex has many similarities with its murine counterpart, but also has some differences. These include active ISC not showing the typical columnar base morphology as well as the absence of bona fide Paneth cells. This is the first description of ISC dynamics during pig’s early life and provides useful reference data for future studies, aimed at targeting ISC for the development of efficient alternatives to in-feed antibiotics for preserving intestinal integrity.
This research reports on a quantitative analysis of the combination of two types of disfluency, reformulations and pauses, in the speech of lower intermediate and advanced speakers of English as a second language (L2). The present study distinguishes between corrections and false starts within the category of reformulations as well as between silent and filled pauses. It focuses on the extent to which pause behavior within reformulations varies according to the stage of L2 development and the type of reformulation used. An analysis was made of 56 L2 speakers’ 2-min monologues. The results showed that lower intermediate and advanced speakers differed on the frequency of silent pauses inserted in corrections but not on their frequency in false starts. This suggests that false starts depend less on proficiency level, and may reflect temporary problems with conceptual encoding or extralinguistic factors that contribute to the efficacy of L2 production rather than difficulties with linguistic processing per se. The frequency of silent pauses rather than silent pause duration or the frequency and duration of filled pauses appeared to be the only marker to differentiate between false starts and corrections across the two proficiency groups.
The proteins produced just prior to maturation desiccation in the developing, orthodox seed, are stored in the desiccated state and recruited as the functional proteome upon imbibition. For the resumption of protein function, these stored proteins must be protected from permanent denaturation while dehydrating, throughout desiccation, and during rehydration. For some forms of damage there is the possibility of repair following imbibition potentially coordinated with de-aggregation into monodispersed polypeptides capable of refolding into a functional configuration. While studying aspects of the natural protection and repair mechanism in seeds, evidence has accrued that those proteins directly involved in translation are particular targets of both protection and protein repair. Such a phenomenon was first described by Rajjou et al. (2008) examining the frequency with which proteins involved in translation were identified as differentially abundant between aged and un-aged Arabidopsis seeds and the translational competence of aged versus un-aged seeds. The inference drawn from these observations was that, of all the stored proteins, it is imperative that those involved in translation endure desiccation, quiescence and rehydration in a functional state if the seed is to survive. Proteins involved in any other process other than translation can be replaced from the stored transcriptome or by de novo transcription but no mRNA is of value without the translational machinery. This has become known as ‘Job's rule’ in honour of the laboratory from which this hypothesis was first put forward (Rajjou et al., 2008). We review in this manuscript the evidence accrued to date on which Job's rule is based.
