The Use of Digital Media Art Using UI and Visual Sensing Image Technology
Authors: Mao Tong , Jiang Xunxun
Published: November 2021

Visual sensing image technology has narrowed the distance between people and art with the rapid development of digital media, but new art forms continue to appear. Therefore, this exploration is aimed at studying the application of visual image technology based on user interface (UI) and virtual reality (VR) technology in art. This exploration is to explore the development path of digital media art. The concept of UI is briefly discussed. Based on the current means of visual sensing technology, UI, visual sensing image technology, and digital media art are successfully combined after the close relationship between digital media and art is realized. The results show that VR technology, which combines UI and visual sensing technology, has good compatibility with digital media art and can further shorten the distance between digital media art and the public. Moreover, the promotion of this application can greatly increase users’ experience of VR. In addition, most people hold a more positive attitude towards this combination. It reveals that it is essential to apply UI and visual sensing image technology to digital media art.
Study on Heart Rate and Energy Expenditure in College Sports Training Based on Multisensor Perception
Authors: Liu Ge , Liu Baiqing
Published: November 2021

Heart rate is one of the important indices to calculate and evaluate the intensity and quality of motion. It can scientifically and objectively reflect the intensity level of momentum and exercise in the process of exercise. It is an important index of athletic strength and physical fitness of athletes in college sports training. This paper analyzes the basic metabolic model of the human body and energy supply and demand model and constructs a scientific energy consumption test model for special sports activity. An algorithm for heart rate detection and energy consumption based on acceleration data acquisition is proposed. Therefore, it is proposed to calculate motion acceleration using bone point data obtained from a portable telephone camera sensor for special sports activity and to calculate kinetic energy consumption through detection data. A model for evaluating the proposed algorithm is also established.
Application of Neural Network Algorithm Based on Principal Component Image Analysis in Band Expansion of College English Listening
Authors: Hao Cailing
Published: November 2021

With the development of information technology, band expansion technology is gradually applied to college English listening teaching. This technology aims to recover broadband speech signals from narrowband speech signals with a limited frequency band. However, due to the limitations of current voice equipment and channel conditions, the existing voice band expansion technology often ignores the high‐frequency and low‐frequency correlation of the audio, resulting in excessive smoothing of the recovered high‐frequency spectrum, too dull subjective hearing, and insufficient expression ability. In order to solve this problem, a neural network model PCA‐NN (principal components analysis‐neural network) based on principal component image analysis is proposed. Based on the nonlinear characteristics of the audio image signal, the model reduces the dimension of high‐dimensional data and realizes the effective recovery of the high‐frequency detailed spectrum of audio signal in phase space. The results show that the PCA‐NN, i.e., neural network based on principal component analysis, is superior to other audio expansion algorithms in subjective and objective evaluation; in log spectrum distortion evaluation, PCA‐NN algorithm obtains smaller LSD. Compared with EHBE, Le, and La, the average LSD decreased by 2.286 dB, 0.51 dB, and 0.15 dB, respectively. The above results show that in the image frequency band expansion of college English listening, the neural network algorithm based on principal component analysis (PCA‐NN) can obtain better high‐frequency reconstruction accuracy and effectively improve the audio quality.
On the Many Dimensions of Complexity in Heritage Languages
Authors: Laleko Oksana , Scontras Gregory
Published: November 2021

Heritage languages are often discussed in terms of their (reduced) complexity, but few attempts have been made to objectively measure the complexity of heritage languages. Here we explore various approaches to the investigation of language complexity, discussing three broad areas of inquiry: (i) attempts to objectively measure grammatical complexity, (ii) the potential role of socio-demographic factors in explaining variability in complexity, and (iii) considerations beyond grammatical complexity, which include the various aspects of complexity invoked when language is used for the purpose of communication. At each point, we highlight potential wisdom to be drawn from existing studies of heritage languages, which help to inform hypotheses for future study. The upshot is that complexity in heritage languages is itself a complex phenomenon – an observation that calls into question traditional characterizations of heritage languages in terms of an overall decrease in complexity.
Representational and Computational Changes in Heritage Language Grammars
Authors: Montrul Silvina
Published: November 2021

The notion of complexity has been applied to descriptions and comparisons of languages and to explanations related to ease and difficulty of various linguistic phenomena in first and second language acquisition. It has been noted that compared to baseline grammars, heritage language grammars are less complex, displaying morphological simplification and structural shrinking, especially among heritage speakers with lower proficiency in the language. On some recent proposals of gender agreement in Spanish and Norwegian (Fuchs et al., 2015; Lohndal & Putnam, 2020), these differences are representational, affecting the projection of functional categories and feature specifications in the syntax. An alternative possibility is that differences between baseline and heritage grammars arise from computational considerations related to bilingualism, affecting speed of lexical access and feature reassembly online in the minority language. We illustrate this proposal with empirical data from gender agreement and differential object marking. Although presented as alternatives, the representational and computational explanations are not incompatible, and may both be adequate to capture varying levels of variability modulated by linguistic proficiency. These proposals formalize bilingual acquisition models of grammar competition and directly relate the availability and type of input (the acquisition evidence) to the locus and nature of the grammatical differences between heritage and baseline grammars.
Penelope’s αἰνοπαθῆ (σ 201)
Authors: Lundquist Jesse
Published: November 2021

The Homeric hapax αἰνοπαθής ‘terribly suffering’ has been adduced as evidence for ancient processes of Indo-European word-formation. In particular, the vocalism of the root, α of -παθ-, would derive from *n̥, an ablaut grade conditioned by the accent on the ending -ής (a “hysterokinetic” s-stem adjective). I reexamine the passage where the word is found and argue the vocalism of -παθής reflects not an archaism but an innovation in Homeric Greek. Using this reanalysis as a point of departure, I review recent literature on s-stem adjectives in Greek, Vedic, and Proto-Indo-European, disputing that the evidence suffices for a hysterokinetic reconstruction. I propose that the PIE accent was borne on the first member of these exocentric compounds as we find it in earliest Old Indic, in the prehistory of Greek, and in certain Greek archaisms.
The Homeric Dependency Lexicon
Authors: Zanchi Chiara
Published: November 2021

This paper presents the Homeric Dependency Lexicon (HoDeL), a new resource with a user-friendly interface facilitating the study of Homeric verbs and dependents. HoDeL was induced from the analytical layer of AGDT 2.0, extracting all dependents tagged as SBJ, OBJ, PNOM, and OCOMP with a set of SQL queries. The paper illustrates HoDeL functionalities and shows how they can be employed by researchers to answer specific research questions about the Homeric language. Introducing the uses of HoDeL offers the opportunity to reexamine some crucial, though frequently underestimated, methodological challenges concerning annotated corpora and resources derived from them that relate to the linguistic theories underlying annotations and error propagation. It is argued that the careful documentation of how linguistic resources were created, what data they contain, and how they can be queried through their dedicated interfaces is essential to lay the groundwork for users’ investigations.
Καλημέρα, kalimera or kalhmera?
Authors: Mouresioti Evgenia , Terkourafi Marina
Published: November 2021

Although language attitudes are frequently investigated, how these attitudes change over time is studied less frequently, despite providing an interesting window into the link between attitudes and ideologies. Conducted some twenty years since the first studies on this topic, the current study provides an updated perspective into language attitudes toward the use of Roman-alphabeted Greek (henceforth, Greeklish) in emails and SMS messages exchanged between Greek native speakers. Adapting the matched guise methodology commonly used in language attitude research to visual stimuli, we collected data from 60 participants of different ages and genders. Overall, their attitudes toward Greeklish were markedly negative, confirming negative attitudes already expressed twenty years prior but also extending them. We propose that technological and demographic but also ideological factors underlie the negative attitudes toward Greeklish expressed by Greek native speakers today.
Religious Subcultures and Reading Culture
Authors: van de Kamp Jan
Published: November 2021

For religious subcultures, the reading of religious books was of great importance, even for Roman Catholics, renowned for their ritual-mindedness and the prevailing limitations in terms of religious reading for laypeople. This article aims to reveal the extent to which the status and role of a subculture affected the printing history and reception of religious books. The Post-Reformation Low Countries – split into the South, where the Catholics were a dominant culture, and the Dutch Republic in the North, where they were a subculture – provides an excellent case study. A very popular meditation book serves as the source for the study, namely Sondaechs Schoole (Sunday school) (1623).
EU or UK Child-Sponsored Family Reunification Policy: Who’s Right? Whose Rights?
Authors: Downes Chris
Published: November 2021

The increase in numbers of children travelling unaccompanied to Europe has provoked a sensitive debate as to how to treat their family members. While EU Member States generally grant family reunification for unaccompanied minors, the UK has opted to permit reunion in only ‘exceptional circumstances’. Widely criticised, the UK government counters that child-sponsored family reunification creates incentives for unaccompanied migration that place children at risk. This article explores both policies from a human rights perspective. It suggests that, as regards children reaching Europe, EU policy is more consistent with human rights norms. However, UK policy raises legitimate questions about obligations towards children beyond Europe’s borders. A rights-based justification for either EU or UK policy can be constructed, but requires recourse to additional principles on the balancing of rights among different groups of children. Clearer articulation and scrutiny of these principles could strengthen the rights rationale for child-sponsored family reunification.
Public Security Revisited
Authors: Knäbe Timo , Caniard Hervé Yves
Published: November 2021

With its Judgment of 27 November 2019 in Case T-31/18 Luisa Izuzquiza and Arne Semsrott v European Border and Coast Guard Agency (Frontex), the Court of Justice of the European Union opened a new chapter in the elaboration of the two seemingly antagonistic interests enshrined in Regulation (EC) No 1049/2001 of 30 May 2001 regarding public access to European Parliament, Council and Commission documents: the public’s fundamental right to transparency versus the public’s interest as regards “public security”. Focusing on the evolution of “public security” in the EU since 1993, this case note analyses the CJEU’s balancing of these principles, its increased scrutiny of Frontex administrative decisions, and the extent to which Frontex had to justify its denial to grant access to documents through the lens of the management of sensitive operational information. This examination puts the judgment in the context of the ongoing situation in the central Mediterranean and, by providing detailed insights on the underlying operational considerations, shows that the fundamental and wide-reaching right to transparency has to be balanced with the need to protect crew and vessels and the implementation and enforcement of the Frontex mandate. While continuing established case law in its use of the public security exception (a so-called absolute exception that is not subject to an overriding public interest test), in this case the CJEU subsumed, for the first time, individual subjective rights and legal interests under public security. This article argues that this amounts to the individualisation of public security. As pointed out by Frontex in its written and oral defence, the CJEU thus opened the door to extending the scope of public security to also include other groups of people in the government’s continuous and exclusive de jure and de facto control. The conclusion from the Frontex Case is thus that protecting life at sea and ensuring effective border surveillance are two sides of the same medal as they have a common aim: combatting human smugglers, traffickers in human beings and other criminals and safeguarding life, safety and physical integrity of law-enforcement crew and migrants alike.
Princess Elisabeth’s Cautions and Descartes’ Suppression of the Traité de l’Homme
Authors: Cook Harold J.
Published: November 2021

Why did Descartes not publish his chief physiology work during his lifetime? Descartes considered that the physiological and medical conclusions that could be drawn from his philosophy were fundamental to his intellectual project, and an apparently complete work was circulating among friends in 1641 but was only published more than a decade after his death, as De Homine (1662) and Traité de l’Homme (1664). This paper argues that Princess Elisabeth’s careful consideration of his physiology raised questions about whether the common interpretation of his philosophy as dualistic was correct, implicating it in some of the most dangerous arguments of his generation. Her questions served as a warning, in a moment when the personal papers and even the liberty of the Frenchman were threatened. Descartes had no interest in becoming a medical Galileo, and listened to the princess, leaving the work unpublished.
Medina and Mecca Revisited
Authors: Witkam Jan Just
Published: November 2021

The illustrations of Medina and Mecca in al-Ǧazūlī’s prayer book Dalāʾil al-Khayrāt have drawn the attention of many scholars, who have come up with different interpretations. In the present article, a subgroup within the Maghribī manuscripts of that text is defined for the first time: luxury manuscripts that date from the 11–12th/17–18th centuries and that were mostly produced for important owners, certainly in Morocco, possibly in other parts of the Magrib. The manuscripts in this subgroup have an illustrated and illuminated addition that physically precedes the text of Dalāʾil al-Khayrāt, but that does not belong to the text of the prayer book. In the present article that addition is for the first time identified as such and described. A small corpus has been assembled and, by way of example, the article contains a detailed description of two manuscripts belonging to that newly defined subgroup: MS Paris, Bibliothèque nationale de France, Arabe 6983, and MS Berlin, Staatsbibliothek, Or. oct. 240.
In Writing and in Sound
Authors: Göloğlu Sabiha
Published: November 2021

Copies of Dalāʾil al-Khayrāt (Proofs of Good Deeds) by the Moroccan Sufi saint Muḥammad b. Sulaymān al-Jazūlī (d. 870/1465) were in high demand in the eighteenth- and nineteenth-century Ottoman Empire. This required producing manuscripts in large numbers and, later, printing the text. These mostly lithographic copies and corpora of the Dalāʾil al-Khayrāt, when combined with references to biographical dictionaries, inheritance records, inventories, library catalogues, and endowment deeds, reveal a great deal of information about the public and private prevalence of the text, within and beyond the empire. The Dalāʾil al-Khayrāt appealed to many individuals, from Ottoman sultans to royal women, and from madrasa students to members of the learned class. Its copies were endowed to mosques and libraries, held in different book collections of the Topkapi palace, and were available from booksellers. Be it silently or aloud, the Dalāʾil al-Khayrāt could be read in private homes and in mosques from Istanbul to Medina, a feature of pious soundscapes across the empire.
The Shifting Status of Cities in International Law? A Review, Several Questions and a Straight Answer
Authors: Nesi Giuseppe
Published: November 2021

Witnessing the sometimes confusing and often nebulous debate on the position of cities in international law, one could wonder what cities are and what they do in contemporary international law. One could also wonder whether allowing cities to actively participate in the formation and implementation of international norms, and to contribute to international multilateral negotiations on issues of global concern such as sustainable development, climate change or human rights, does really imply a change in their status in international law. In this contribution, the reasons why cities are not subjects of international law, or better, why cities and local authorities still matter in international law because they are part of a State, are systematically assessed. Specific attention is paid to the status and role of transnational city networks. Before concluding, this article makes some final comments on the prospects for cities and transnational city networks in international law.
Paradoxes of Visibility and Preservation: Cultural Heritage Law and the Making of the City as an International Legal Category
Authors: Lixinski Lucas
Published: November 2021

The push for cities to be a part of international legal governance processes is tied to the promise of bridging international law’s democratic deficit. However, the exercise of cities’ personality in international law can end up replicating many of the same democratic deficits with which international law is usually charged. Therefore, cities as agents may be an unsatisfactory way of addressing international law’s democratic deficits. Instead, cities as objects can raise the visibility of cities and the local communities that live therein, but without giving agency to a State actor. This visibility can then pave the way for communities themselves to be directly involved in international legal governance processes. This article uses the example of international heritage law, where cities are very significantly represented in international heritage lists and even a specific instrument (the 2011 Recommendation on the Historic Urban Landscape) to showcase the limitations and possibilities of the project of cities in international law. I argue that there is a paradox of visibility and agency that permeates international legal possibilities for cities, and placing the city simultaneously in the registers of object and subject ultimately defers the central question of community involvement in international law on global public goods.
Sustainable Development as a Cornerstone of Cities’ Engagement with International Law
Authors: Pavoni Riccardo
Published: November 2021

Sustainable development may safely be regarded as a cornerstone of cities’ engagement with international law, an engagement which is certainly bound to increase in the time of COVID-19. This article revisits the historical trajectory of cities’ and local governments’ participation in sustainable development processes. It particularly focuses on the contemporary involvement of cities and their transnational networks in the United Nations 2030 Agenda for Sustainable Development and associated Sustainable Development Goals. Subsidiarity and public participation are fully discussed as conceptual underpinnings of cities’ growing role in the pursuit of sustainability. The article concludes that, as long as cities continue to demonstrate leadership and innovation in advancing cutting- edge solutions to problems of sustainability as a result of mechanisms that secure the meaningful participation of the communities of people concerned, their place in the global partnership for sustainable development will inevitably become ever more prominent.
The Urban-Rural Divide: Spatial Inequalities and Backlash in the Investment Treaty Regime
Authors: Litwin Daniel
Published: November 2021

A growing literature in international law has examined the backlash against international institutions and norms and its links with the rise of nationalist parties and populism. Some of this backlash have been said to originate with populations in small towns and rural areas socioeconomically “left-behind” by economic globalization. These developments have made salient the growing economic and political polarization between urban and non-urban areas. Nevertheless, this urban- rural divide and its implications for international law have only started to be acknowledged. Aligned with these concerns, this article adopts the urban-rural divide as a geographical scale or frame to suggest a new perspective on the investment treaty regime, its backlash and reform. Outside of the particularly virulent nature of its backlash, the regime’s context provides fertile ground for this frame: it is structured so that urban actors principally located in global or capital cities, such as multinational enterprises, global law firms, or national executive branches, make decisions about foreign investment projects that are often located and impact non-urban areas and populations. As this article contends, this context points to the regime’s potential to impact (and address) through geographical affinities the global growth of political and economic polarization between urban and nonurban areas. The impact of these urban decisions on non-urban areas has so far principally been examined through frames that emphasize impact in terms of the “environment” or “local communities” together with calls for reforms to the regime by allocating more policy space for States. An “urban-rural” frame centers additional impacts in terms of non-urban public interest, local participation, and the distribution of resources, and queries the ability of domestic policies alone to respond to them in the pursuit of socially and economic inclusive investment.
Cities and Countryside: An International Law Perspective
Authors: Francioni Francesco
Published: November 2021

Cities, as spaces of socio-cultural organization and economic interaction among people, have always played a dominant role in the development and implementation of international law. Today, a new strand of legal scholarship focuses on cities and local communities as competitors and partners with the nation State in a new project of modernization and democratization of international law. This paper looks at this new trend against the background of the historical narrative of cities in the development of international law. At the same time, it calls attention to the fact that half of humanity still lives and works in rural areas, in the vast countryside of the world. Rural communities have been the servants of the city since the beginning of time. Today, their dignity and rights are beginning to be recognized by acts of the United Nations such as the 2007 Declaration of the Rights of Indigenous Peoples and the 2018 Declaration on the Rights of Peasants. Yet, these people remain a disadvantaged and vulnerable class. A true modernization and democratization of international law requires that we keep a balanced approach to the legal recognition of the voices and rights of urban communities and those of the people who work and live in the countryside of the world.
The Enrica Lexie Award Amid Jurisdictional and Law of the Sea Issues
Authors: Cataldi Giuseppe
Published: November 2021

This article analyzes the Enrica Lexie Arbitral Award, first of all, in relation to international law issues concerning the application of the United Nations Convention on the Law of the Sea (UNCLOS). The article then focuses on the question of the functional immunity of the two marines, from the point of view of the Tribunal’s assertion of its incidental jurisdiction to deal with the matter, as well as of the Tribunal’s affirmation of the existence of a customary international law rule applicable in the present case. Both conclusions appear unconvincing, also in light of the role of the two marines on board a merchant ship. In any case, the fact remains that the judgment has the merit of finally putting an end to a long-standing dispute, to the satisfaction of the two parties involved.
A Satisfactory Answer? The Enrica Lexie Award and the Jurisdiction Over Incidental Questions
Authors: Marotti Loris
Published: November 2021

This article situates the Enrica Lexie award’s stance on the Tribunal’s jurisdiction over the marines’ immunity within the broader debate on the scope of the jurisdiction of international courts and tribunals over incidental questions. After illustrating the Tribunal’s approach to the question at hand, the paper appraises those instances where an international tribunal with limited jurisdiction can decide issues and apply rules that are “external” to its principal jurisdiction. It then focuses on the question of the jurisdiction over incidental issues, which is the most debated avenue for an international tribunal to engage with substantive matters falling outside the scope of the tribunal’s ratione materiae jurisdiction. Finally, the Tribunal’s approach in the Enrica Lexie award is critically assessed against the above debate. It is submitted that, although the award arguably put an end to the longstanding dispute between India and Italy, the Tribunal’s reasoning does not seem to be in line with the conditions for the exercise of jurisdiction over incidental questions as roughly sketched in relevant case law.
Functional Immunity of the Marines on the Enrica Lexie: A Reply To Raffaella Nigro
Authors: Ronzitti Natalino
Published: November 2021

This article is a short reply to Raffaella Nigro’s assessment of the Arbitral Tribunal award in the Enrica Lexie case. Professor Nigro analyzes the rule of functional immunity of State officials from foreign criminal jurisdiction and argues that it cannot be applied to the two marines, even supposing that military personnel are covered by such a rule. Professor Nigro bases this conclusion on the facts that the marines were stationed on a commercial vessel and were servicing the interests of the private shipowner.

In reply, this author reaffirms the existence of a rule of customary international law on functional immunity and argues that military personnel assigned to commercial vessels are carrying out these duties in order to protect Italian interests and contribute to the defeat of piracy. Therefore, the marines on board the Enrica Lexie were (and still remain) under the protection of the rule on immunity from foreign criminal jurisdiction.
Null effects of neighbourhood increases in visible minorities on radical right wing party mobilisation
Authors: Kawalerowicz Juta , Hjorth-Trolle Anders
Published: November 2021

In many European countries, a growing share of population with immigrant background coincides with the surge in support for radical right parties. In this paper we show how such increases affect radical right candidacy. We use Swedish register data which identifies political candidates. With geocoded data, we match individuals running for the Sweden Democrats to their local neighbourhood contexts, and measure changes in the share of visible minority residents at scales ranging from 100 meters to 2 kilometres. For those who stayed in the same neighbourhood between 2006 and 2010, the change in the share of visible minorities generally does not affect the decision to join the pool of party candidates. This result is robust when we introduce additional tests and select on the scale of the neighbourhood, unemployment terciles, change in share of visible minority groups terciles, and entry threshold into the pool of candidates. For those who stayed in the same neighbourhood, the only significant finding is a small mobilisation effect for a subsample of individuals who live in densely populated metropolitan neighbourhoods – here we also observe a halo effect, with negative association for small-scale changes and positive association for changes in the larger halo zone.
Management of the Crura During Laparoscopic Sleeve Gastrectomy
Authors: Tobin Edward C. , Knotts Chelsea , Tsai Jonathon , Austin Jeffrey , Thompson Stephanie , Attia Christina G. , Richmond Bryan K. , Monnett Shane
Published: November 2021

Despite the increasing number of bariatric procedures being performed, the optimal strategy for managing the crura during laparoscopic sleeve gastrectomy (LSG) remains controversial. Options include no closure, primary suture closure, and suture closure with mesh reinforcement. We sought to investigate outcomes associated with each technique and determine if any approach proved to be superior.

Methods

This is a retrospective cohort study that evaluated patients undergoing LSG performed by a single surgeon in a 7-year period. Data were collected via chart review. The primary endpoint was hiatal hernia presence at 5 years post-operatively. Secondary endpoints included post-procedural complications (nausea, vomiting, dysphagia, or reflux) at 30 days post-operatively.

Results

A total of 361 patients were included in the analysis: 154 without crural closure, 164 primary crural closure, and 43 primary crural closure with mesh reinforcement. Rates of hiatal hernia occurrence at 5 years were 9.7% (no closure), 14.0% (primary closure), and 16.3% (closure with mesh reinforcement), respectively, and did not differ significantly among the 3 cohorts (P = .37). Overall rates of 30-day complications were 11.5%, 21.5%, and 28.6%, respectively ( P = .015).

Conclusion

Rates of hiatal hernia after sleeve gastrectomy do not differ, regardless of management of the crura. In addition, and perhaps more significantly, avoidance of crural closure was associated with fewer 30-day complications. In fact, the highest rate of 30-day complications was seen in the group that received closure with mesh reinforcement. These data suggest that crural closure during LSG should be avoided. Further prospective study of these findings is warranted.
Mechanisms of Injury Among the Amish Population in Central Pennsylvania
Authors: Whitney Larissa , Bonneville Kelly , Morgan Madison , Perea Lindsey L.
Published: November 2021

Background

Individuals presenting with traumatic injury in rural populations have significantly different injury patterns than those in urban environments. With an increasing Amish population, totaling over 33 000 in our catchment area, their unique way of life poses additional factors for injury. This study aims to evaluate differences in mechanism of injury, location of injury, and demographic patterns within the Amish population. We hypothesize that there will be an increased incidence of agriculture-related mechanisms of injury.

Methods

All Amish trauma patients presenting to our level I trauma center over 20 years (1/2000-4/2020) were retrospectively analyzed. Mechanism and geographic location of injury were collected. Demographic and clinical variables were compared between the age groups.

Results

There were 1740 patients included in the study with 36.4% (n = 634) ≤ 14 years. Only 10% (n = 174) were ≥ 65 years. The most common mechanism across all ages was falls. However, when separating out the pediatric population ( ≤ 14 years), 27.8% (n = 60) fell from a height on average > 8-10 feet. The most common geographic location of injury was at home in all age groups, except for the 15-24 year group, which was roadways.

Discussion

The Amish population poses a unique set of mechanisms of injury and thus injury patterns to rural trauma centers. We have found the most common injuries to be falls, buggy accidents, animal-related injuries, and farming accidents across all age groups. Future research and collaboration with other rural trauma centers treating large Amish populations would be beneficial to maximize injury prevention in this population.

Virilizing Adrenocortical Carcinoma Resected With Negative Margins Treated With Surgery Alone
Authors: Fields Tyler , Felux Kelsee , Chavarriaga Alejandro , Ramsay Philip , Weitman Evan
Published: November 2021

Adrenocortical carcinoma is a rare malignancy. A virilizing adrenocortical carcinoma is even more unique of a diagnosis. In this report, we present a rare case of this uncommon tumor with an interesting presentation, clearly documented physical exam changes over a span of at least 8 years, and a technically challenging case. We also briefly review the management of adrenocortical carcinoma. The tumor was successfully resected with no planned adjuvant treatment at this time. The patient had recurrence of menstrual cycle post-operatively and required no steroid supplementation.
Is Pathological Exam for Disorders of the Appendix Testis Necessary?
Authors: Pickering John M. , Hunt H. William , Bhattacharya S. Dave
Published: November 2021

Testicular appendages are remnants of embryologic structures commonly encountered during pediatric operations. The literature is vague on the management of incidentally discovered testicular appendages found intraoperatively. We performed a retrospective review of 93 pediatric patients who were found to have an incidental testicular appendage during inguinal hernia repair, cryptorchidism, or testicular torsion cases from December 2017 to June 2020. 100% of the incidental testicular appendage pathology results were benign. All of the specimens were 1.0 cm or less in their largest dimension. Removal of these specimens is considered the standard of care at our institution to help prevent torsion of the testicular appendage, which is one of the leading causes of acute scrotum in children. The authors of this study argue that pathological analysis is unnecessary and may result in excessive use of resources without proven benefit.
Restrictive Pulmonary Dysfunction May Increase Blood Loss During Liver Resection
Authors: Yoshikawa Takahiro , Hokuto Daisuke , Yasuda Satoshi , Kamitani Naoki , Matsuo Yasuko , Sho Masayuki
Published: November 2021

Background

Restrictive pulmonary dysfunction (RPD) is a risk factor for perioperative complications during gastrointestinal surgery. We hypothesized that high airway pressure due to RPD results in increased intraoperative blood loss during liver surgery. Thus, we investigated the effects of RPD on perioperative outcomes for liver resection.

Methods

This study included 496 patients who underwent curative liver resection at our hospital between April 2009 and April 2020. Perioperative outcomes for the RPD and control groups were compared. Restrictive pulmonary dysfunction was defined as % vital capacity <80%.

Results

Forty-one patients (8.3%) had RPD. No significant differences were observed in intraoperative blood losses (440 mL vs 320 mL, P = .340), overall complication rates (29.3% vs 31.2%, P = .797), or pulmonary complication rates (4.9% vs 9.0%, P = .286) between the RPD and control groups. In the 256 patients who underwent anatomical liver resection, 18 patients (7.0%) had RPD. The intraoperative blood loss was significantly higher in the RPD group (925 mL vs 456 mL, P = .013), but no differences in the overall complication rates (44.4% vs 37.3%, P = .528) or pulmonary complication rates (11.1% vs 10.5%, P = .589) between the two groups were detected. A multivariate analysis showed that RPD was an independent risk factor for intraoperative blood loss ≥500 mL during anatomical liver resection (odds ratio 4.132; 95% confidence interval 1.135-15.045; P = .031).

Discussion

Restrictive pulmonary dysfunction may be a risk factor for intraoperative blood loss during anatomical liver resection, which requires exposure of the main hepatic vein.
Assessing the Risk of Repeat Victimization Using Structured and Unstructured Police Information

Published: November 2021

Following the EU Victim Directive, Dutch police officers are obliged to assess a victim’s vulnerability to repeat victimization. This study explored the utility of unstructured police information for the prediction of repeat victimization, as well as its incremental value over and above structured police information. Police records over a period of 6 years were retrieved for a sample of 116,680 victims. Unstructured information was transformed into numeric features using count-vector and TF/IDF methods. Classification models were built using decision tree and random forest models. AUC values indicate that a combination of structured and unstructured police information could be used to correctly classify a majority of repeat and non-repeat victims.
Beyond the “Ferguson Effect” on Crime: Examining its Influence on Law Enforcement Personnel

Published: November 2021

The purpose of the current study is to examine the influence tensions over high-profile officer-involved shootings have had on Atlanta police officers’ ability to do their jobs and whether these impacts vary by officer race. Data was collected between August and October of 2016. A total of 241 police officers across six zones completed the self-administered survey. Findings indicate that while white officers, on average, felt the impacts of recent tensions surrounding officer-involved shootings more strongly, non-white officers were more likely to say they would leave policing if offered a better paying job in another field. This study provides insight into racial differences in the impacts of recent tensions and protests over fatal officer-involved shootings.

The article by Hastings and Schwarz, Leading Change Processes for Success: A Dynamic Application of Diagnostic and Dialogic Organization Development (OD), deserves close review by scholars and practitioners. Their research supports arguments that OD approaches can be meaningfully categorized as diagnostic or dialogic and that differences in those approaches have significant implications for organizational change success rates. Concerns about how one assesses a leader's mindset and counterpoints to the conclusion that oscillation between diagnostic and dialogic approaches is always associated with higher success rates are presented.

The influence of succession on organisational sustainability has been widely acknowledged globally, but studies focusing specifically on farms remain relatively limited. This article examines the factors influencing succession in the newly occupied farms under the fast track land reform programme in Zimbabwe and their implications for the sustainability of the land reform programme. The study followed a qualitative multi-case research design. Data were collected using a combination of unstructured interviews, informal discussions, lived experience narrations and direct observations. Notwithstanding other structural and institutional constraints, the absence of succession arrangements and the politics of survival have been found to be the major threats to sustainability.

This study was a quasi experiment involving 470 school children who were survivors of abduction in Northern Nigeria. There were two interventions: the first was a face-to-face counselling, while the second was a visual multimedia counselling intervention. The result of the study showed that at baseline, all the respondents reported high school dropout propensity. However, after the treatment, respondents in the visual multimedia group reported lower school dropout propensity when compared to their counterparts in the face-to-face counselling. The researchers made recommendations based on the results of the study.
The effect of loading rate on the in-plane shear strength of tri-axial braided composites
Authors: May Michael , Kilchert Sebastian
Published: November 2021

The in-plane shear strength of tri-axial braided composite materials was measured for three different braid angles (30°, 45°, and 60°) and two strain rates (0.001 s−1; 3 s−1) using the three-rail shear test. The in-plane shear strength was found to be sensitive to both—the braid angle and the strain rate. An increase of braid angle resulted in a reduction of shear strength, whilst an increase of loading rate resulted in an increase of shear strength of 8%–17%, depending on the braid angle.

In the self-assembly process of β-Si3N4 (SN)/316L stainless-steel (SUS316L) composite materials tailored via sintering of powder mixtures, the formation of a SN agglomerate resulting from condensation–dispersion reactions during the stirring of SN/SUS316L was found to play an important role in improving the thermal conductivity. Moreover, the obtained SN secondary particle groups connected to form a network through diffusion-limited aggregation. In particular, it was shown that the sample prepared at the milling speed of 150 r/min has a similar particle group area (about 1.38 μm2) to that at 120 r/min, but a higher κ (increased from 9.5 W m−1 K−1 to 11.5 W m−1 K−1). To quantitatively evaluate the microstructural morphology of the texture of the self-assembled composite material, global parameters τ( q) and D q and local parameters α( q) and f( α) were determined via multifractal analysis. These characteristics of the anisotropy, dispersion, and cohesiveness of the particle network in the material texture could be analyzed together with the capacity dimension D0, information dimension D1 (configuration entropy), correlation dimension D2, and α( q) (related to internal energy). The results suggest that α( q) reflects the differences in the cohesion of the additive particle agglomeration that constitutes the self-assembly process under the solid-state reaction.
Analysis of the characteristics of air–yarn coupling movement in the profiled reed groove of an air-jet loom

Published: November 2021

The movement characteristics of yarn in the profiled reed groove of an air-jet loom can have a great impact on the performance of the fabric. Unstable yarn movement tends to lead to weft defects, as short wefts or weft breaks may occur, which could deteriorate the quality of the final fabric. In this paper, the characteristics of the yarn movement in a profiled reed groove are numerically studied. The arbitrary Lagrangian–Eulerian method is used to solve the two-way airflow–yarn interaction and the yarn is simulated with the ball–socket model. A fluctuation ratio is defined to characterize the unsteadiness of the yarn movement. Our simulation first investigates the effect of the gap ratio of the profiled reed groove (β) on the yarn movement then compares the movements of different yarn kinds. The simulation results indicate that a larger β not only decreases gas leaks (thus saves gas consumption), but also stabilizes the yarn movement. Our simulation results also show that the movement of the yarn of polypropylene is more stable than the other two weft-yarn materials. An experiment is also conducted to validate our numerical results, which shows a favorable agreement between them. Our numerical results of the yarn movement in the profiled reed groove can provide a valuable insight into the optimization of the weft insertion system of the air-jet loom.

The Maricopa County Department of Public Health (MCDPH) Sexually Transmitted Disease (STD) Clinic remained operational during a 6-week statewide Coronavirus Disease 2019 (COVID-19) Stay-at-Home Order. The present study sought to evaluate the effect of the Stay-at-Home Order on countywide STD reporting and uptake of sexual health services. We compared countywide daily median STD reporting and MCDPH STD clinic attendance across 3 timeframes; (1) Pre-Lockdown (01/01/2020–03/30/2020); (2) Lockdown (03/31/2020–05/15/2020); and (3) Post-Lockdown (05/16/2020–12/31/2020). STD reporting was characterized as incident chlamydia, gonorrhea, and primary and secondary syphilis. Clinic attendance was characterized as clients visiting through express testing or provider visits. Differences in STD reporting and clinic attendance were evaluated using non-parametric testing. Comparing Pre-Lockdown to Lockdown, we observed significant declines in the daily median chlamydia case reporting (−22%) and clinic express testing attendance (−29%). Comparing Lockdown to Post-Lockdown, we observed significant increases in daily median chlamydia and gonorrhea case reporting (+20%, +15%; respectively) and clinic express testing and provider visits (+42%, +20%; respectively). No significant difference was observed in countywide syphilis reporting across the 3 timeframes. Declines in STD reporting were observed countywide during the lockdown and were concurrent with declines in attendance observed at the MCDPH STD Clinic. Maintenance of clinic operations during the lockdown allowed for continued uptake of STD testing, diagnosis, treatment, and partner services. This study of sexual health care utilization at the public STD clinic in Maricopa County, Arizona, found reduced testing and provider visits contributed to lower countywide STD reporting during the Arizona COVID-19 Stay-at-Home Order.
