An updated review on surface functionalisation of titanium and its alloys for implants applications

Deposition of bioactive and degradable coatings on titanium implants before implantation is objectively to create a biologically-inspired surface that can enhance cell anchorage at the initial stage of implantation and facilitate osseointegration at the later stage of implantation. Therefore, this review paper is aim to discuss the surface functionality of titanium and its alloys regarding its physical structure, chemical composition and biological reaction through its deposited coatings of the altered surface. This review begins by explaining the working fundamentals of biomaterials and present methods used to adjust the titanium surface for biomedical applications, followed by the concept of biocompatibility of the coated surfaces of the titanium-based implant and the mechanism for adapting the affected surface to its bioimplanted environments. The paper also discusses the possible challenges of biocompatibility of the bioactive coating on titanium for implants. Intriguingly, the usability of 3D-printing technology as an implant surface modification technique is addressed in this recent study. In addition to the existing review papers on the surface modification of titanium-based implants, this current review contributes to the outline concept of biocompatible coated titanium. Herein, the outlined principle focused on the osseointegration mechanisms within coated titanium to its implanted environment, most of which are based on recent findings and are further adopted by today's influential literature on titanium surface modification and its alloys.

Sait Faik Abasıyanık’ın Seçilmiş Üç Öyküsünde Zaman, Mekân ve Ahlak

One of the most influential Turkish literature authors after the post-republic period, Sait Faik Abasıyanık pursued virtue and morality in his literary work, although literary critics have not underlined this aspect of his work. In his non-didactic and open-ended stories, the perception of morality he adopted is quite evident. Analyzing Sait Faik’s selected stories in the context of their temporal and spatial settings, this study aims to resolve the moral equation manifested. In this paper, three randomly selected short stories by Abasiyanik were studied to understand how he perceived morality and how the subject of morality is treated in his select short stories. His short stories The Old Teenager, The White Gold, and Just a Story were studied in terms of how the selected subject, morality, appears in these texts. While analyzing these stories, it is recognized that the author was affected from the space and time in and during which he lived and wrote in Istanbul.

Geophysical inversion for 3D contact surface geometry

Geologists’ interpretations about the earth typically involve distinct rock units with contacts between them. Three-dimensional geologic models typically comprise surfaces of tessellated polygons that represent the contacts. In contrast, geophysical inversions typically are performed on voxel meshes comprising space-filling elements. Standard minimum-structure voxel inversions recover smooth models, inconsistent with typical geologic interpretations. Various voxel inversion methods have been developed that attempt to produce models more consistent with such interpretations. However, many of those methods involve increased numerical challenges and ultimately the underlying parameterization of the earth is still inconsistent with geologists’ interpretations. Surface geometry inversion (SGI) is a fundamentally different approach that effectively takes some initial surface-based model and alters the position of the contact surfaces to better fit the geophysical data. Many authors have developed SGI methods. In contrast to those, we are the first to develop a method with the following characteristics: we work directly with 3D explicit surfaces from an input geologic model of arbitrary complexity; we incorporate intersection detection methods to avoid unacceptable topological scenarios; we use global optimization strategies and stochastic sampling to solve the inverse problem and aid model assessment; and we use surface subdivision to reduce the number of model parameters, which also provides regularization without adding the complication of trade-off parameters in the objective function. We test our methods on simpler synthetic examples taken from early influential literature, and we demonstrate their typical use on a more complicated example based on a seafloor massive sulfide deposit. Our work provides a geophysical inversion approach that can work directly with 3D surface-based geologic models. With this approach, geophysical and geologic models can share the same parameterization; there is only a single model, with no need to translate information between two inconsistent parameterizations.

Reputation-Sourced Authority and the Prospect of Unchecked Bureaucratic Power.

We explore the democratic implications of a reputational account of bureaucratic authority. While an influential literature has examined the relevance of reputation—and mutual exchange between principals and agents in public organizations generally—the normative implications of these insights have largely escaped scrutiny. We discuss how reputation‐building impacts both the ability and the motivation of principals to oversee administrative policymaking. We argue that reputation‐sourced authority eschews ex ante incentives through the claims‐making and maneuvering of bureaucrats as they develop reputations with audiences. At the same time, it de‐legitimizes ex post oversight because monitoring and compliance must compete both with reputational authority and with resistance from the audiences that are the very sources of such authority.

Visualizing the knowledge domain of multimodal discourse analysis (2009-2019): A bibliometric review

Different from traditional discourse analysis, multimodal discourse analysis (MDA), a systematic analysis of different semiotic modes, utilizing language, images, sounds in a discourse, emphasizes the coordination of both dynamic and static semiotic resources. This study presents the status quo and development trend of the research field through an objective, systematic, and comprehensive review of relevant publications available from the Web of Science Core Collection. Analysis techniques including a descriptive statistical method and a bibliometric method are used. The study quantitatively analyzes the publications in terms of general characteristics, geographical distribution, high-cited representatives, and topic discovery and distribution to illustrate the development and trend of MDA. The research findings are as follows: (1) In the past 10 years or so, international MDA research has presented a significant growth trend, with flourishing research output, interest and diversification of presented subjects; (2) New topics are constantly emerging, with research topics mainly focusing on the development of visual grammar, gesture, digital technologies, conference presentations, metonymy and metaphor, etc.; (3) Research focuses mainly on multimodality, semiotics, conversation analysis, critical discourse analysis etc.; (4) The article also listed a series of important and highly influential literature, countries, journals and authors on MDA during different periods. It is hoped that this paper can provide a reference for the further study of MDA.

Worlding beyond ‘the’ ‘end’ of ‘the world’: white apocalyptic visions and BIPOC futurisms

We often hear that the ‘end of the world’ is approaching – but whose world, exactly, is expected to end? Over the last several decades, a popular and influential literature has emerged, in International Relations (IR), social sciences, and in popular culture, on subjects such as ‘human extinction’, ‘global catastrophic risks’, and eco-apocalypse. Written by scientists, political scientists, and journalists for wide public audiences,1 this genre diagnoses what it considers the most serious global threats and offers strategies to protect the future of ‘humanity’. This article will critically engage this genre to two ends: first, we aim to show that the present apocalyptic narratives embed a series of problematic assumptions which reveal that they are motivated not by a general concern with futures but rather with the task of securing white futures. Second, we seek to highlight how visions drawn from Black, Indigenous and People of Color (BIPOC) futurisms reimagine more just and vibrant futures.

Cyber parental control: A bibliometric study

Cyber parental control is a multidisciplinary field that aims to provide a safe Internet environment for children by authorizing parents or guardians to practice control on their children in using Internet access. Literature investigates and reviews cyber parental control from different perspectives, such as the risks associated with the cyber network, the roles of parents, the psychological and legal implications, and the technological aspects. However, there is a lack of studies on the bibliometric analysis report that demonstrates the research trend in cyber parental control. This study aims to present a thorough bibliometric and network collaboration analysis of cyber parental control research practices in the last twenty years. This analysis begins by identifying over 2700 unique literature items that were published between 2000 and 2019 in the Scopus and ISI Web of Science databases. Using bibliometric analysis, this study identifies the most influential literature, determines the topical discipline areas, and provides insights for current research trends and directions for the future on the research of cyber parental control. The findings provide a robust roadmap for further investigation in this field. This study also highlighted the taxonomy of cyber parental control tools and their filtering techniques. Finally, it presented several open challenges on cyber parental control as future research directions.

ESTIMATING INTENSIVE AND EXTENSIVE TAX RESPONSIVENESS

Influential literatures have exploited tax policy changes to estimate the effects of income taxes on either intensive or extensive margin decisions. We extend this quasi‐experimental approach to jointly estimate intensive and extensive margin tax elasticities to address selection issues that have hindered consistent estimation of labor supply effects. The extensive margin equation provides a way to control for selection in the intensive margin equation while consistent estimation of the intensive margin provides estimates of after‐tax returns to working for nonworkers, a necessary input to study extensive behavioral responses. We apply this approach to study the tax responsiveness of older workers. (JEL C33, H24, J20, J26)

The Scholarship of Research Degrees: Influential Publications and Influential Writers in the Discipline of Doctoral Education

The results of a survey of the international community of scholars and professionals involved in the practice and study of doctoral education are reported. Its purpose was to identify the most influential publications in the discipline and its most influential writers. The use of citation analysis as a method is discussed, and the reasons for rejecting it are explained. Instead, an online questionnaire was developed and participation invited through an email circulated via the mailing lists of a number of relevant and regularly-held conferences across the world, a number of relevant Jiscmail mailing lists, a number of relevant LinkedIn groups and other channels. A total of 151 individuals accessed the questionnaire, although not all completed it in full. In addition to identifying the most influential publications and the most influential writers in the discipline of doctoral education, the paper also analyses the gender patterns of the authorship of the identified publications. The range of influential publications items including books (109), articles (94), short works/chapters (12) and reports and other items (34) addressing a broad range of topics. The most common countries from which first authors were drawn is Australia, the UK and the US. Of the most frequently 13 nominated works, all but one had first been published after 2000, and five of them had male first-authors and the remaining eight female. Of the 16 most influential writers identified by respondents, all but two are female and the list includes individuals drawn from five countries (Australia, UK, US, Canada and Aotearoa/New Zealand). The article provides a guide to influential (and potentially useful) literature for use in development activities designed for research students, their supervisors and others involved in the practice and management of doctoral education. It also identifies areas for further research.

Effects of Ballot Type and District Magnitude on Local Public Goods Bill-Initiation Behavior: Evidence from Honduras

An influential literature predicts that incentives to provide local public goods are conditioned by how electoral systems expose a legislator to the need to seek a personal vote. Carey and Shugart theorize that district magnitude and ballot type interact affecting the legislators’ personal vote-seeking behavior. Another literature challenges the idea that electoral systems affect the behavior of legislators, particularly in highly clientelist settings, usually associated with high poverty. I empirically evaluate these arguments on an original data set of local goods bills presented by legislators of the National Congress of Honduras between 1990 and 2009. Honduras changed its electoral system from closed-list to open-list in 2004 while keeping its district magnitude constant. The results suggest that the Ballot Type × District Magnitude interaction does not affect the behavior of legislators in small magnitude constituencies, where poverty is more significant. However, support for the hypotheses is found in the largest, more developed constituency where M is equal to twenty-three seats.

Adverse Selection into Competition: Evidence from a Large-scale Field Experiment in Tanzania

An influential literature has shown that women are less willing to compete than men, and the gender gap in competition may contribute to explaining gender differences in educational choices and labor market outcomes. This study reports from a large-scale randomized controlled trial of a women empowerment program in Tanzania targeting young women at the end of secondary school. Combining the randomized controlled trial, a lab-in-the-field experiment and survey data, we provide evidence suggesting that the program caused adverse selection into competition: low performing women competed more, while there was no effect on the high performers. We provide a theoretical framework to illustrate an adverse selection mechanism that may contribute to explain why the program only affected the willingness to compete among low performers. Our results emphasize the importance of understanding sorting mechanisms and heterogeneous treatment effects in the design of policies and programs.

Ecospirituality and sustainability transitions: agency towards degrowth

ABSTRACT‘Sustainability transitions’ has emerged as one of the most important and influential literatures on understanding the pathways towards a more sustainable future. Yet, most approaches in this literature privilege technological and regime-wide innovations, while people’s agencies, grassroots innovations, and social factors more generally are often underrepresented. This article focuses on the role of ecospirituality as worldview, aiming to understand how spiritual and religious beliefs play an important role in practical, everyday sustainability transitions. In an extensive desk-based study, literature across disciplines is reviewed to explore connections between spirituality, pro-environmental behaviour, climate policy, and sustainability agencies. Showing the importance of ecospiritual practice, the purpose of this article is to make a case for the inclusion of ecospirituality, as worldview, in the study of sustainability transitions. We argue that ecospirituality is a significant dimension to understanding people’s contemporary agencies that shift away from endless economic growth and resource efficiency mantras towards more radical worldviews of degrowth and different ways of achieving happiness and fulfilment in life.

A Bibliometric Analysis of Green Supply Chain Management Based on the Web of Science (WOS) Platform

To analyse the research progress and frontier dynamics of green supply chain management, this paper uses Web of Science’s citation database to search and filter related documents from 2007–2018. A total of 1391 articles were obtained. On this basis, a bibliometric analysis method was utilized to study the literature characteristics and research hotspots of green supply chain management research. Our results show the following: (1) The current amount of published literature on the field of green supply chain management is exponentially increasing. Research on green supply chain management tended to develop after 2013. (2) The current research on green supply chain management has not formed a core author group and among the literatures on green supply chain management, only a few authors reported some influential literatures. (3) It can be seen from the comprehensive average citation frequency and the number of publications that Hong Kong Polytechnic University, University of Southern Denmark and others have a strong research capability and a large field influence in the field of green supply chain management research. (4) There are 13 core journals publishing the research of green supply chain management, covering 10 fields including engineering, mathematics and social issues. (5) At present, the research hotspots of green supply chain management mainly include the following: Green production and innovation, green supply chain management theory and method, and sustainable supply chain environment and performance. Finally, this paper analyses the shortcomings of previous research and proposes a future direction for research development.

On Being (Not) Old: Agency, Self-care, and Life-course Aspirations in the United States.

This article examines U.S. endeavors to eradicate old age. Drawing on research with older, mostly white, Americans across social classes, I probe how older people engage in "healthy," "successful" aging as a moral project, health identity, and way of approaching the life course. Moving beyond influential literature on biopolitics and biomedicine that tends to treat medicine, science, and biopolitical governance as overdetermined causal forces, I explore instead how a confluence of factors-including cultural ideologies of personhood and independence, medical interventions, social hierarchies, and individual experiences-together lead to the stigmatization of oldness. Social inequalities also matter, as an ethos of self-care and individual agency to ward off oldness is most pronounced among the able-bodied and socioeconomic elite. The aim is to illuminate the convergence of factors that stigmatize oldness in contemporary North America, while highlighting the ways that class profoundly figures in people's varied attempts to not be old.

Students, their Protests, and their Organizations. Exploring Old Gaps and New Evidence

While introducing the four contributions to the special issue Students, their protests, and their organizations: exploring old gaps and new evidence, we link them with influential literature on students' protests and their organizations. The 'old gaps' refer to the long-standing divide between two traditions of research in students' collective action: social movements and organizational studies. The 'new evidence' refers to the finding that studentship is not conducive to protests (Oana 2019a), while the father's education is a strong predictor. While the 'agentic' character of studentship is one important presumption behind many arguments making sense of campus unrest, this finding does not invalidate it as such, but rather indicates that selection to higher education, and not campus socialization, may be conducive to this form of political participation.

The Out of Africa Hypothesis of Comparative Economic Development: Common Misconceptions

The importance of the prehistoric migration of anatomically modern humans from Africa for comparative economic development has been the focus of a vibrant research agenda in the past decade. This influential literature has attracted the attention of some scholars from other disciplines, and in light of existing methodological gaps across fields, has perhaps unsurprisingly generated some significant misconceptions. This article examines the critical views expressed by some scholars from other disciplines, and establishes that they are based on fundamental misunderstandings of the statistical methodology, the conceptual framework, and the scope of the analysis that characterize this influential literature..

Demographic Engineering and International Conflict: Evidence from China and the Former USSR

AbstractWhen and where do states coercively alter their internal demography? We build a theory that predicts under what conditions states alter the demographic “facts on the ground” by resettling and expelling ethno-national populations. We predict that, under particular scope conditions, states will employ demographic engineering to shore up control over (1) nonnatural frontiers, and (2) areas populated by ethnic minorities who are co-ethnics with elites in a hostile power. We then substantiate our predictions using new subnational data from both China and the USSR. Causally identifying the spatially differential effect of international conflict on demographic engineering via a difference-in-differences design, we find that the Sino-Soviet split (1959–1982) led to a disproportionate increase in the expulsion of ethnic Russians and resettlement of ethnic Han in Chinese border areas lacking a natural border with the USSR, and that resettlement was targeted at areas populated by ethnic Russians. On the Soviet side, we similarly find that the Sino-Soviet split led to a significant increase in expulsion of Chinese and the resettlement of Russians in border areas, and that resettlement was targeted at areas populated by more Chinese. We develop the nascent field of political demography by advancing our theoretical and empirical understanding ofwhen, where, andto whomstates seek to effect demographic change. By demonstrating that both ethnic group concentration and dispersion across borders are endogenous to international conflict, our results complicate a large and influential literature linking ethnic demography to conflict.

An end-to-end process of writing and publishing influential literature review articles

PurposeLiterature reviews are essential tools for uncovering prevalent knowledge gaps, unifying fragmented bodies of scholarship, and taking stock of the cumulative evidence in a field of inquiry. Yet, successfully producing rigorous, coherent, thought-provoking, and practically relevant review articles represents an extremely complex and challenging endeavor. The purpose of this paper is to uncover the key requirements for expanding literature reviews’ reach within and across study domains and provide useful guidelines to prospective authors interested in generating this type of scientific output.Design/methodology/approachDrawing upon the authors’ own experience of producing literature reviews and a scrutiny of review papers in major management journals, the authors develop an end-to-end process of writing and publishing review articles of high potential impact.FindingsThe advanced process is broken down into two phases and seven sequential steps, each of them being described in terms of key actions, required skill sets, best practices, metrics of assessment and expected outcomes.Originality/valueBy tapping into the inherent complexity of review articles and demystifying the intricacies associated with pursuing this type of scientific research, the authors seek to inspire a wealth of new influential surveys of specialized literature.

Leniency, Status and Output Informativeness

The article identifies the condition under which it is beneficial for the principal to be a lenient performance evaluator towards his/her favourite agent. It provides the game theoretic foundation behind the decision of choosing leniency (biased) over stringency (fair). The emergence of an influential literature captures the different aspects of status as a non-monetary incentive and its significance in organisational theory. However, the interplay between status and evaluation system has not been studied much. The article is built over an article by Dey and Banerjee (2014a) to understand the role of status incentive with the leniency of evaluation. Analysis of the interplay between status and leniency shows that when status is valued more, the principal benefits from this form of biasness. Interestingly, this article also provides a linkage between informativeness of output signal with this form of biasness. Using moral hazard framework with limited liability in a discrete effort framework, it is suggested that a weak output signal can act as an instrument in reducing the emergence of a lenient evaluation.

An estimate of the average cumulative royalty yield in the world mobile phone industry: Theory, measurement and results

An influential literature argues that dispersed patent ownership may lead to royalty stacking and excessive running royalties, thus increasing the long-run marginal cost of manufacturing phones and their prices. One set of estimates claims that the royalty stack is on the order of 20–40 percent of the value of the average phone. In order to assess this claim, we estimate the average cumulative royalty yield—the sum total of patent royalty payments earned by licensors, divided by the total value of mobile phones shipped— in the world mobile phone industry between 2007 and 2016.We “follow the money” and identify, with varying accuracy, 39 potential licensors in the smartphone value chain. We find that, of these, only 29 charged royalties in 2016, running from a low of $1.6 million to a high of $7.7 billion, summing to $14.2 billion in total, which compares with $425.1 billion in mobile phone sales. The average cumulative royalty yield in 2016 was 3.3 percent or $7.20 per phone. If we restrict this only to smartphones, the result would be $9.60 per phone, roughly 3.4 percent of the average selling price. A sensitivity analysis shows that even under a very restrictive set of assumptions, the average cumulative royalty yield on a smartphone would not exceed 5.6 percent.
