Like other livestock sectors, the Canadian egg industry has evolved substantially over time and will likely experience similarly significant change looking forward, with many of these changes determining the sustainability implications of and for the industry. Influencing factors include: technological and management changes at farm level and along the value chain resulting in greater production efficiencies and improved life cycle resource efficiency and environmental performance; a changing policy/regulatory environment; and shifts in societal expectations and associated market dynamics, including increased attention to animal welfare outcomes—especially in regard to changes in housing systems for laying hens. In the face of this change, effective decision-making is needed to ensure the sustainability of the Canadian egg industry. Attention both to lessons from the past and to the emerging challenges that will shape its future is required and multi- and interdisciplinary perspectives are needed to understand synergies and potential trade-offs between alternative courses of action across multiple aspects of sustainability. Here, we consider the past, present and potential futures for this industry through the lenses of environmental, institutional (i.e., regulatory), and socio-economic sustainability, with an emphasis on animal welfare as an important emergent social consideration. Our analysis identifies preferred pathways, potential pitfalls, and outstanding cross-disciplinary research questions.

This chapter presents the physiological metrics used in Games User Research (GUR). Aimed at GUR professionals in the games industry, it explains what methods are available to researchers to measure biometric data while subjects are engaged in play. It sets out when it is appropriate to use biometric measures in GUR projects, the kind of data generated, and the differing ways it can be analysed. The chapter also discusses the trade-offs required when interpreting physiological data, and will help games researchers to make informed decisions about which research questions can benefit from biometric methodologies. As the equipment needed to collect biometric data becomes more sophisticated as well as cheaper, physiological testing of players during a game’s development will become more common. At the same time, Games User Researchers will become more discriminating in its use. Where in the past professionals in the games industry have used biometric testing to generate quick, actionable feedback about player responses to elements of a game, and have been less concerned with the scientific robustness of their methodology, as GUR develops a new breed of games industry professionals are attempting to deploy good academic practice in their researches.

History Of

This epilogue argues that historians ought to be able to produce a universal history, one that would ‘cover’ the past of humankind ‘as a whole’. However, aside from the always increasing difficulty of mastering the factual material that such an undertaking requires, there exists another difficulty: the coherence of universal history always presupposes an initial decision not to write about the human past in all its multiplicity, but to focus on one aspect of that past. Nevertheless, the lure of universal history will persist, even in the face of its practical and conceptual difficulty. Certainly, it is possible to imagine a future ideological convergence among humans that would enable them to accept, as authoritative, one history of humankind.

AbstractAlloplastic facial transplantation has become a new rung on the proverbial reconstructive ladder for severe facial wounds in the past couple of decades. Since the first transfer including bony components in 2006, numerous facial allotransplantations across many countries have been successfully performed, many incorporating multiple bony elements of the face. There are many unique considerations to facial transplantation of bone, however, beyond the considerations of simple soft tissue transfer. Herein, we review the current literature and considerations specific to bony facial transplantation focusing on the pertinent surgical anatomy, preoperative planning needs, intraoperative harvest and inset considerations, and postoperative protocols.

Traditional Approaches

Facial expression recognition has been an active area of research over the past few decades, and it is still challenging due to the high intra-class variation. Traditional approaches for this problem rely on hand-crafted features such as SIFT, HOG, and LBP, followed by a classifier trained on a database of images or videos. Most of these works perform reasonably well on datasets of images captured in a controlled condition but fail to perform as well on more challenging datasets with more image variation and partial faces. In recent years, several works proposed an end-to-end framework for facial expression recognition using deep learning models. Despite the better performance of these works, there are still much room for improvement. In this work, we propose a deep learning approach based on attentional convolutional network that is able to focus on important parts of the face and achieves significant improvement over previous models on multiple datasets, including FER-2013, CK+, FERG, and JAFFE. We also use a visualization technique that is able to find important facial regions to detect different emotions based on the classifier’s output. Through experimental results, we show that different emotions are sensitive to different parts of the face.

A 24-year-old woman was referred because of incompletely-controlled complex partial seizures. Her seizures had started at age 21, after a mild head injury with brief loss of consciousness incurred in a biking accident, and were characterized by a sensation of bright flashing lights in the right visual field, followed by numbness and tingling in the right foot, spreading up the leg and to the arm, ultimately involving the entire right side, including the face. Occasionally they spread further to involve right facial twitching with jerking of the right arm and leg, loss of awareness and, at the onset of her epilepsy, rare secondarily generalized convulsions. Seizure frequency averaged three to four per month. She was initially treated with phenytoin and clobazam and subsequently changed to carbamazepine 800 milligrams per day. She also complained that her right side was no longer as strong as her left and that it was also numb, especially the leg, but felt that this weakness had stabilized or improved slightly over the past two years.

The Face

At least since Matthew Arnold exploited the term Zeitgeist in Literature and Dogma, the expression has been variously a source of irritation and confusion to a number of his critics. Identifying it with a tendency to disparage the past, an exasperated contemporary reviewer of that work in Blackwood's Edinburgh Magazine cried, “Can anything be more unscientific than such a spirit? It is the very apotheosis of self-opinion intoxicated by its own pride, and flaunting its own dogmatisms with a crude audacity in the face of preceding dogmas.” Among other critics of Arnold, R. H. Hutton protested that the Zeitgeist was a will-o'-the-wisp “who misleads us at least as much as he enlightens”; W. H. Dawson concluded that for Arnold it was “a fetish, a talisman, a thaumaturgy”; for W. H. Paul it became a bore; Hugh Kingsmill began his caricature of Don Matthew, “So forth he sallied, mounted on Zeit-Geist, a hobby horse.” Still others, less annoyed than these by the reiteration, have themselves borrowed it as they write of him—sometimes effectively, because with consistency of meaning, as H. F. Lowry in his edition of Arnold's letters to Clough; sometimes bewilderingly, as when one reads such a statement as this: “Expediency, which had become in Burke's hands an anti-revolutionary doctrine, was equated by Arnold with the Zeitgeist, a force which, in his conception of it, was quite as revolutionary as that of natural right.”

Background: Since the past two decades, the Lagos seaports have experienced vessel and storage yard cargo congestion, resulting in dwell times of about 30 days for containerised imports and high trade logistics costs.Objectives: The purpose of this study was to identify the critical factors that impact the operational efficiency of the Lagos seaports with a view to improving liner trade activities.Method: The study adopted an operational-based approach to understand the dynamics of the various interfaces of the port value chain. The research paradigm adopted for the study was therefore a combination of constructivism and post-positivism paradigms, which entailed the exploration and understanding of the various stakeholders in the port value chain. The epistemology of the research relied on the use of the exploratory sequential mixed method research technique (i.e. the qualitative approach followed by the quantitative approach) at the operational level of port operations.Results: The result of the research showed that significant challenges exist and that some of these challenges cut across all functions of port operations. Challenges are experienced in the areas of corruption, trade fraud, transport infrastructure deficits, the absence of a supply chain culture and shortcomings in the execution of the ‘contract of customs’. Additionally, these factors include the deficiencies in services and facilities provided by state agencies and government-appointed service providers and private sector companies such as truckers, inland container depots, Inland Container Depots (ICDs) and terminal operators.Conclusion: Specific recommendations are made to address the issues identified which, if implemented, could significantly address the current inefficiencies observed in the Lagos seaport’s operations.
