Network Pattern

As a new product of the Internet and big data era, migration data are of great significance for the revealing of the complex dynamic network patterns of urban agglomerations and for studying the relations between cities by using the “space of flows” model. Based on Baidu migration data of one week in 2021, this paper constructs a 30 × 30 rational data matrix for cities in Zhongyuan Urban Agglomeration and depicts the network pattern from static and dynamic perspectives by using social network analysis and dynamic network visualization. The results show that the network of Zhongyuan Urban Agglomeration is characterized by a circular structure with Zhengzhou as the center, a city belt around Zhengzhou as the connection, subcentral cities as the support and peripheral cities as the extension. Zhengzhou is the core city of the entire network, related to which the central and backbone networks divided in this paper account for nearly 40% of the total migration. Shangqiu, Luoyang, Zhoukou and Handan also play an important role in the structure of the migration network as subcentral cities. For a single city, the migration scale generally peaks on weekends and reaches its minimum during Tuesday to Thursday. Regarding the relations between cities, the migration variation can be divided into four types: peaking on Monday, peaking on weekends, bimodal and stable, and there are obvious phenomena of weekly commuting. In general, the links between cities outside Henan Province and other cities in the urban agglomeration are relatively weak, and the constraints of administrative regionalization on intercity migration are presumed to still exist. According to the results, the location advantage for multi-layer development and construction of Zhongyuan Urban Agglomeration should be made use of. In addition, the status as the core city and the radiation range should be strengthened, and the connections between the peripheral cities and the other cities should be improved, so as to promote the integrated and efficient development of the whole urban agglomeration.

Abstract This foreword frames the Symposium in two ways. It summarises the core themes running through the nine ‘meditations’ in The Status of Law in World Society. Moreover, it places these themes in the wider context of Kratochwil's critical engagement with how we pursue knowledge of and in the social world and translate this knowledge into action. Ultimately, also his pragmatic approach cannot escape the tensions between theory and practice. Instead, we are in the midst of both.

AbstractHeterogeneous IoT-enabled networks generally accommodate both jitter tolerant and intolerant traffic. Optical Burst Switched (OBS) backbone networks handle the resultant volumes of such traffic by transmitting it in huge size chunks called bursts. Because of the lack of or limited buffering capabilities within the core network, burst contentions may frequently occur and thus affect overall supportable quality of service (QoS). Burst contention(s) in the core network is generally characterized by frequent burst losses as well as differential delays especially when traffic levels surge. Burst contention can be resolved in the core network by way of partial buffering using fiber delay lines (FDLs), wavelength conversion using wavelength converters (WCs) or deflection routing. In this paper, we assume that burst contention is resolved by way of deflecting contending bursts to other less congested paths even though this may lead to differential delays incurred by bursts as they traverse the network. This will contribute to undesirable jitter that may ultimately compromise overall QoS. Noting that jitter is mostly caused by deflection routing which itself is a result of poor wavelength and routing assigning, the paper proposes a controlled deflection routing (CDR) and wavelength assignment based scheme that allows the deflection of bursts to alternate paths only after controller buffer preset thresholds are surpassed. In this way, bursts (or burst fragments) intended for a common destination are always most likely to be routed on the same or least cost path end-to-end. We describe the scheme as well as compare its performance to other existing approaches. Overall, both analytical and simulation results show that the proposed scheme does lower both congestion (on deflection routes) as well as jitter, thus also improving throughput as well as avoiding congestion on deflection paths.

ArgumentAnimals played an important role in the formation of psychoanalysis as a theoretical and therapeutic enterprise. They are at the core of texts such as Freud's famous case histories of Little Hans, the Rat Man, or the Wolf Man. The infantile anxiety triggered by animals provided the essential link between the psychology of individual neuroses and the ambivalent status of the “totem” animal in so-called primitive societies in Freud's attempt to construct an anthropological basis for the Oedipus complex in Totem and Taboo. In the following, we attempt to track the status of animals as objects of indirect observation as they appear in Freud's classical texts, and in later revisionist accounts such as Otto Rank's Trauma of Birth and Imre Hermann's work on the clinging instinct. In the 1920s and 1930s, the Freudian conception of patients' animal phobias is substantially revised within Hermann's original psychoanalytic theory of instincts which draws heavily upon ethological observations of primates. Although such a reformulation remains grounded in the idea of “archaic” animal models for human development, it allows to a certain extent to empiricize the speculative elements of Freud's later instinct theory (notably the death instinct) and to come to a more embodied account of psychoanalytic practice.

The aim of this paper is to investigate the issue of intertextuality in the novel Alfirdaws Alyabab (The Waste Paradise) by the female Saudi novelist and short story writer Laila al-Juhani. Intertextuality is a rhetoric and literary technique defined as a textual reference deliberate or subtle to some other texts with a view of drawing more significance to the core text; and hence it is employed by an author to communicate and discuss ideas in a critical style. The narrative structure of Alfirdaws Alyabab (The Waste Paradise) showcases references of religious, literary, historical, and folkloric intertextuality. In analyzing these references, the study follows the intertextual approach. In her novel The Waste Paradise, Laila al-Juhani portrays the suffering of Saudi women who are less tormented by social marginalization than by an inner conflict between openness to Western culture and conformity to cultural heritage. Intertextuality relates to words, texts, or discourses among each other. Moreover, the intertextual relations are subject to reader’s response to the text. The relation of one text with other texts or contexts never reduces the prestige of writing. Therefore, this study, does not diminish the status of the writer or the text; rather, it is in itself a kind of literary creativity. Finally, this paper aims to introduce Saudi writers in general and the female writers in particular to the world literature.

Integration development of urban agglomeration is important for regional economic research and management. In this paper, a method was proposed to study the integration development of urban agglomeration by trajectory gravity model. It can analyze the gravitational strength of the core city to other cities and characterize the spatial trajectory of its gravitational direction, expansion, etc. quantitatively. The main idea is to do the fitting analysis between the urban axes and the gravitational lines. The correlation coefficients retrieved from the fitting analysis can reflect the correlation of two indices. For the different cities in the same year, a higher value means a stronger relationship. There is a clear gravitational force between the cities when the value above 0.75. For the most cities in different years, the gravitational force between the core city with itself is increasing by years. At the same time, the direction of growth of the urban axes tends to increase in the direction of the gravitational force between cities. There is a clear tendency for the trajectories of the cities to move closer together. The proposed model was applied to the integration development of China Liaoning central urban agglomeration from 2008 to 2016. The results show that cities are constantly attracted to each other through urban gravity.

The provisions governing the euro as ‘European Single Currency’ are at the core of the Treaty on the Functioning of the European Union’s (TFEU) rules on the Economic Monetary Union (EMU). Since the euro has replaced the former national currencies of the participating Member States and is to substitute the national currencies of any future members of the euro area, it was mandatory to ascribe to the euro the status of exclusive ‘legal tender’ as per Article 128(1) TFEU. This status of the euro seems to be so evident as to be self-explanatory–but only at first glance since the concept of ‘legal tender’ and its implications in European Union (EU) and national private and public law are less clear. A satisfactory concept of legal tender is hard to define and hardly ever given on the EU level–resulting in a striking lack of legal certainty in a great variety of aspects of public and private law.

This article presents and analyses how Tanzania, a country on the global “periphery” with a natural resource sector dominated by capital from the Global North, has thus far failed to transform its mineral wealth into sustained economic development. Using Immanuel Wallerstein’s “world systems theory” as the theoretical framework, we exemplify how the “core” exploited gold reserves in the 1990s and into the new century – and what techniques and mechanisms (e.g. asymmetry of information, imposition of inadequate management structures) it now currently uses to develop the nascent gas sector to its advantage. Scrutinising actions undertaken by the Tanzanian president to concentrate power, root out corruption, and to stand up to profit-maximising foreign corporations – or what we call the “Magufuli effect” – as way of illustration, we also demonstrate how Tanzania is trying to change its role within the international division of labour and how the core attempts to maintain the status quo meanwhile.

Benefit And Risk

The need to adopt an electronic health record (EHR) system in United States (U.S.) hospitals seems to be more and more obvious when evaluating the benefits of improved patient safety, quality of care, and efficiency. The purpose of the study was to identify the status of EHR systems in U.S. hospitals in regard to the core functionalities implemented (as identified by the Institute of Medicine) and to determine if there was a significant relationship between perceived level of benefit and risk with the use of each core functionality, as well as if there was a significant relationship between the status of the EHR system and size of hospital. A national survey of U.S. hospitals was conducted to answer the research questions. The results showed that 37% had some components in all.of the core functionalities of an EHR system, while 27% were using at least some functionalities. Health information and data, administrative processes, and results management were the three core functionalities that a majority of hospitals had as a part of their EHR system. A significant positive correlation between perceived benefits and risks was found in all of the eight core functionalities. There was no significant relationship found between status of EHR system and size of hospitals.
