This study attempts to examine the direct impact of corporate social responsibility initiatives on employees’ job performance and the indirect relationships between CSR initiatives on employees’ job performance via industrial relations climate and psychological contract fulfillment. Data were collected from 764 supervisor–subordinate dyads and 271 middle managers from 85 companies. Using a multilevel approach, the results showed that organizational-level CSR was positively related to employees’ job performance. Moreover, the industrial relations climate and psychological contract fulfillment played mediating effects between CSR (...) initiatives and job performance. This study provides novel theoretical evidence for why and how CSR initiatives improve job performance. Theoretical and practical implications for implementing CSR initiatives are discussed.

Deliberative democracy is one of the best designs that could facilitate good public policy decision making and bring about epistemic good based on Mercier and Sperber's (M&S's) theory of reasoning. However, three conditions are necessary: (1) an ethic of individual epistemic humility, (2) a pragmatic deflationist definition of truth, and (3) a microscopic framing power analysis during group reasoning.

Based on their framework, Müller & Schumann (M&S) propose a staged drug policy that matches well the neoliberal governance scheme. To mend the sad loss of the sociocultural dimension in their model, I propose three such considerations: first, sociocultural interactions with the brain; second, sociocultural context and justice of drug use; and third, sociocultural preparedness for implementing their drug policy.

BackgroundThis study aimed to elucidate the influence of dementia etiologies on the degree of caregiver burden and determine which factors predict a high caregiving burden.MethodsThis 18-month retrospective cohort study enrolled 630 patients and their caregivers from the Dementia Center of Changhua Christian Hospital. The care team performed face-to-face interviews every 6 months, for 18 months from when a diagnosis of dementia was made. The primary outcome was the change in Zarit Burden Interview scores. Generalized estimating equations were used for the (...) longitudinal data analysis.ResultsParticipants with Lewy body disease had a significantly higher caregiving burden compared with those with Alzheimer's disease after adjusting for patient and caregiver features. Caregivers of mixed-type dementia and frontotemporal dementia experienced a greater burden than caregivers of AD, at 6- and 18-month follow-up. Patients with more severe dementia, neuropsychiatric symptoms, being cared for by more than two caregivers, or utilizing social resources were associated with higher ZBI scores; the depressive mood of caregiver also predicted higher ZBI scores.ConclusionThis longitudinal study demonstrated that caregiver burden was influenced by the underlying dementia etiology of patients. The dementia care team should provide personalized education and transfer patients and caregivers to appropriate resources, especially for high-risk populations. (shrink)

In China, there have been numerous reports that doctors or other health care workers have been attacked by patients or members of patient’s families. From 2000 to 2003, there were 502 reports of violence against health care workers in the city of Beijing, in which 90 health care workers were wounded or disabled. From January 1991 to July 2001, in Hubei Province, 568 attacks on health care facilities and workers were reported, and some health care workers were even killed. In (...) Jiangsu Province, from 2000 to 2002, violent events against health care facilities and workers increased by 35% every year, with an average of 177 such events occurring each year. Those acts of violence have been attributed, in part, to the inadequacy of the legal system for handling medical disputes that was in effect prior to 2002. (shrink)

Urban streetscapes are outdoor areas in which the general public can appreciate green landscapes and engage in outdoor activities along the street. This study tested the extent to which the degree of awareness of urban street trees impacts attention restoration and perceived restorativeness. We manipulated the degree of awareness of street trees. Participants were placed into four groups and shown different images: (a) streetscapes with absolutely no trees; (b) streetscapes with flashes of trees in which participants had minimal awareness of (...) the content; (c) streetscapes with trees; and (d) streetscapes with trees to which participants were told to pay attention. We compared the performance of 138 individuals on measures of attention and their evaluations of perceived restorativeness. Two main findings emerged. First, streetscapes with trees improved the performance of participants on attentional tests even without their awareness of the trees. Second, participants who had raised awareness of street trees performed best on the attentional test and rated the streetscapes as being more restorative. These findings enhance our knowledge about the role of an individual's awareness of restorative elements and have implications for designers and individuals who are at risk of attentional fatigue.

Visual programming language is a crucial part of learning programming. On this basis, it is essential to use visual programming to lower the learning threshold for students to learn about artificial intelligence to meet current demands in higher education. Therefore, a 3-h AI course with an RGB-to-HSL learning task was implemented; the results of which were used to analyze university students from two different disciplines. Valid data were collected for 65 students in the Science -student group and 39 students in (...) the Humanities -student group. Independent sample t-tests were conducted to analyze the difference between cognitive styles and computational thinking. No significant differences in either cognitive style or computational thinking ability were found after the AI course, indicating that taking visual AI courses lowers the learning threshold for students and makes it possible for them to take more difficult AI courses, which in turn effectively helping them acquire AI knowledge, which is crucial for cultivating talent in the field of AI.

Electric-mechanical equipment manufacturing industries focus on the implementation of intelligent manufacturing systems in order to enhance customer services for highly customized machines with high-profit margins such as electric power transformers. Intelligent manufacturing consists in using supply chain data that are integrated for smart decision making during the production life cycle. This research, in cooperation with a large electric power transformer manufacturer, provides an overview of critical intelligent manufacturing technologies. An ontology schema forms the terminology relationships needed to build two intelligent (...) supply chain management modules for the IM system demonstration. The two core modules proposed in this research are the intelligent supplier selection and component ordering module and the product quality prediction module. The intelligent supplier selection and component ordering module dispatches orders that match the best options of suppliers based on combined analytic hierarchy process analysis and multiobjective integer optimization. In the case study, the intelligent supplier selection and component ordering module demonstrates several acceptable Pareto solutions based on strict constraints, which is a very challenging task for decision makers without assistance. The second module is the product quality prediction module which uses multivariate regression and ARIMA to predict the quality of the finished products. Results show that the R square values are very close to 1. The module shortens the time for the company to accurately judge whether the two semifinished iron cores for the product meet the quality requirements. The component supplier selection module and the finished product quality prediction module developed in this research can be extended to other IM systems for general high-end equipment manufacturers using mass customization.

In his essay “Things Do Not Move,” Sengzhao (374?−414 CE), a prominent Chinese Buddhist philosopher, argues for the thesis that the myriad things do not move in time. This view is counter-intuitive and seems to run counter to the Mahayana Buddhist doctrine of emptiness. In this book chapter, I assess Sengzhao’s arguments for his thesis, elucidate his stance on the change/nonchange of things, and discuss related problems. I argue that although Sengzhao is keen on showing the plausibility of the thesis, (...) he actually views the myriad things as both changing and unchanging and upholds the nonduality of motion and rest. In fact, the nonmoving thesis follows from the discernment that things change from moment to moment without there being any enduring stuff in the process. Among philosophical works that confer a higher ontological status on nonchange over change, Sengzhao’s essay is unique and well worth pondering. (shrink)

Background: Healthcare workers in the front line of diagnosis, treatment, and care of patients with coronavirus disease 2019 are at great risk of both infection and developing mental health symptoms. This study aimed to investigate the following: whether healthcare workers in general hospitals experience higher mental distress than those in psychiatric hospitals; the role played by religion and alexithymic trait in influencing the mental health condition and perceived level of happiness of healthcare workers amidst the stress of the COVID-19 pandemic; (...) and factors that influence the resilience of healthcare workers at 6 weeks' follow-up.Methods: Four-hundred and fifty-eight healthcare workers were recruited from general and psychiatric hospitals, and 419 were followed-up after 6 weeks. All participants filled out the 20-item Toronto Alexithymia Scale, five-item Brief-Symptom Rating Scale, and the Chinese Oxford Happiness Questionnaire.Results: Under the stress of the COVID-19 pandemic, 12.3% of frontline healthcare workers in general hospitals reported having mental distress and perceived lower social adaptation status compared with those working in psychiatric hospitals. Christians/Catholics perceived better psychological well-being, and Buddhists/Taoists were less likely to experience mental distress. The results at 6 weeks of follow-up showed that the perceived lower social adaptation status of general hospital healthcare workers was temporary and improved with time. Christian/Catholic religion and time had independent positive effects on psychological well-being; however, the interaction of Christian/Catholic religion and time had a negative effect.Conclusions: Collectivism and individualism in the cultural context are discussed with regard to alexithymic trait and Buddhist/Taoist and Christian/Catholic religious faiths. Early identification of mental distress and interventions should be implemented to ensure a healthy and robust clinical workforce for the treatment and control of the COVID-19 pandemic. (shrink)

It is widely acknowledged that a fair tax system is one of the most crucial foundations for any country to pursue stable development and human values. So how does a country accomplish tax fairness? This article argues that war finance and domestic economic inequality are two critical conditions. Historically, wars usually create opportunities for countries to enact progressive tax reforms. However, countries’ war finance choices are conditioned by domestic economic inequality. When inequality is low, the political leadership is more likely (...) to secure a consensus of ‘equality of fiscal sacrifice’ between domestic wealthy elites and ordinary citizens. As a result, the leadership can more successfully enact progressive taxation, money creation and non-military spending cuts to pay for the war. Conversely, when inequality is high, the societal redistributive conflict could be more serious. Unable to strike a bargain of fiscal sacrifices without severe social instability, the leadership is expected to resort to a debt-financing strategy, which stifles tax progressivity and fairness. This article compares the United States’ war finance in the Korean and Vietnam Wars and finds supportive evidence. This article has important implications for the pursuits of tax fairness, democratic accountability, and the prospect for peace. (shrink)

The effective controlling and monitoring of an industrial process through the integration of statistical process control and engineering process control has been widely addressed in recent years. However, because the mixture types of disturbances are often embedded in underlying processes, mixture control chart patterns are very difficult for an SPC-EPC process to identify. This can result in problems when attempting to determine the underlying root causes of process faults. Additionally, a large number of categories of disturbances may be present in (...) a process, but typical single-stage classifiers have difficulty in identifying large numbers of categories of disturbances in an SPC-EPC process. Therefore, we propose a two-stage neural network based scheme to enhance the accurate identification rate for MCCPs by performing dimension reduction on disturbance categories. The two-stage scheme includes a combination of a NN, support vector machine, and multivariate adaptive regression splines. Experimental results reveal that the proposed scheme achieves a satisfactory AIR for identifying MCCPs in an SPC-EPC system. (shrink)

This study attempts to identify customer retention strategies for legal software and discusses their effectiveness for three consumer groups (stayers, dissatisfied switchers, and satisfied switchers). Although previous studies propose several antipirating strategies, they do not discuss how to enhance customer intentions to use legal software, which is crucial for software companies. The authors provide four generic retention strategies developed from both antipiracy and customer loyalty literature. The results indicate lower-pricing, legal, communication, and product strategies all enhance customer purchase intentions toward (...) legal software. The lower-pricing strategy is more useful for stayers and dissatisfied switchers, and the communication strategy is most useful for dissatisfied switchers. Both the legal and product strategies have similar impacts on purchase intentions across the three segments. From a firm perspective, a product strategy is most worthwhile and useful across all segments. (shrink)

There is a trend in modern times towards taking the individual’s desire to be the indicator or basis of what the good life would be for the individual. Desire is believed to be an outer expression of an inner voice. The idea is that the individual’s desire shows what matters and therefore what constitutes the good life for her. An assumption is that the desire is knowable. The task for a fulfilled life is to reason out what the desire is (...) and, as a next step, take corresponding rational actions towards its fulfilment. John Rawls is a paradigm case of this approach. What is missing, I believe, in assuming the knowability of desire, is an awareness of the key characteristic of human desire: that is, it is always in a process of formation and change. In this article, I try to explore the problems of seeing desire as capable of being made fully present, by looking at the ideas of Ralph Waldo Emerson, Jacques Derrida, and Adam Phillips. (shrink)

In response to the Covid-19 pandemic, online learning has been carried out in many countries with different types of online learning models being promoted and implemented. In the global pandemic continues, the education environment is forced to change from traditional classroom or blended teaching mode to online learning teaching model. With the outbreak of COVID-19, China was the first to announce that online courses are to be implemented in February 2020. In China, whether online learning can replace traditional offline teaching (...) has become a topic worth discussing. Therefore, this study investigates university students in China by questionnaires and discussions of this topic. The study is based on the Push–Pull Mooring model. Based on 854 valid responses collected from an online survey questionnaire, structural equation modeling was employed to examine the research model. The results show that push effects, pull effects, and mooring effects all significantly influence users' switching intentions from offline to online learning platform. Finally, this study explores whether push–pull–mooring can be a reference for promoting and implementing online learning courses in Chinese colleges and universities in the future after the pandemic.

The concept of work engagement has aroused the interest of many scholars. However, there has been limited academic research in examining how authentic leadership can influence WE, which consequently influences organizational citizenship behavior and task performance. In particular, this study divides WE into cognitive engagement, emotional engagement, and physical engagement to fully reflect the engagement theory. This study introduces three dimensions of WE and tests the theoretical model to validate cognitive engagement, emotional engagement, and physical engagement. Empirical testing using a (...) survey of 151 employees of retail travel agencies in Taiwan revealed that the AL can influence cognitive engagement, emotional engagement, and physical engagement, and also OCB and TP. These analysis results can assist vendors to implement OCB and TP through WE and AL. (shrink)

The sexual revolution that took place in the late 1960s and early 1970s is one of the most profound social changes during the second half of the twentieth century in America. Before the revolution, there existed a norm proscribing premarital sex (PS norm); premarital sex was not accepted. After the sexual revolution, the PS norm no longer existed; premarital sex became accepted. In the literature on how premarital sex became accepted, little attention is given to the institutional change that transpired—the (...) collapse of a sexual norm. This study specifies one micro-mechanism of this social change. Specifically, adopting methodological individualism and the prisoner's dilemma game, I develop a theory that explains how a technological innovation for contraception triggered a change in individuals' perception of premarital sex, which led to their behavioral change. As a result, premarital sex became accepted, and the norm proscribing premarital sex collapsed. I use General Social Survey data to test the hypothesized micro-mechanism of the institutional change. The empirical analysis supports the hypothesis derived from the theory. Based on the above analyses, I discuss two alternative explanations and the issue of teenage pregnancy. (shrink)

Speakers with autism spectrum disorder are found to exhibit atypical pitch patterns in speech production. However, little is known about the production of lexical tones as well as neutral tones by tone-language speakers with ASD. Thus, this study investigated the height and shape of tones produced by Mandarin-speaking children with ASD and their age-matched typically developing peers. A pronunciation experiment was conducted in which the participants were asked to produce reduplicated nouns. The findings from the acoustic analyses showed that although (...) ASD children generally produced both lexical tones and neutral tones with distinct tonal contours, there were significant differences between the ASD and TD groups for tone height and shape for T1/T1N, T3/T3N, and T4/T4N. However, we did not find any difference in T2/T2N. These data implied that the atypical acoustic pattern in the ASD group could be partially due to the suppression of the F0 range. Moreover, we found that ASD children tended to produce more errors for T2/T2N, T3/T3N than for T1/T1N, T4/T4N. The pattern of tone errors could be explained by the acquisition principle of pitch, similarities among different tones, and tone sandhi. We thus concluded that deficits in pitch processing could be responsible for the atypical tone pattern of ASD children, and speculated that the atypical tonal contours might also be due to imitation deficits. The present findings may eventually help enhance the comprehensive understanding of the representation of atypical pitch patterns in ASD across languages. (shrink)

Modern education attaches great importance to interdisciplinary skills, among which computational thinking is a core element, and heralds a new era. IT application has shaped education in the 21st century. Computational thinking has provided further impetus for building an all-encompassing social network and fostering a DIY culture enabled by digital technologies. One empirical study used four apps to test children's development in computational thinking and fluency. The article will help students overcome their fears of coding. Peer reviews provide students with (...) an opportunity to learn from each other and become more motivated. These reviews also serve as feedback for teachers to evaluate students' performance. Experimental design is used in this study, and a peer review system is implemented. Freshmen attending a programming class in a university are used as samples. At the class, students write computer programs with f-Chart, which provides a graphical user interface for students to learn programming logic and design. Zuvio, a cloud-based interactive response system, is used to conduct the peer reviews. The data of this study are analyzed through R. The results show not only an improvement in students' learning performance but also a gap between students' peer review scores and teachers' evaluation scores. Learning feedback and evaluation is crucial to transform education between students and teachers into a sustainable cycle system. (shrink)

This paper offers an historical perspective to the discussion of the relationship between Christianity and nonhuman-human animal relationships by examining the animal protection movement in English society as it first took root in the nineteenth century. The paper argues that the Christian beliefs of many in the movement, especially the evangelical outlook of their faith, in a considerable way affected the character as well as the aims and scope of the emergent British animal welfare movement - although the church authorities (...) did not take an active part in the discussion and betterment of the conditions of animals. An explicitly Christian discourse, important in creating and sustaining the important philanthropic tradition in Britain, mobilized the movement. The paper also traces the gradual decrease of the centrality of the movement's Christian elements later in the century when evolutionary ideas as well as other developments in society shed alternative light on the relationship between human and nonhuman animals and brought about different trends in the movement. This paper sees Christianity not as a static and defining source of influence but as a rich tradition containing diverse elements that people drew upon and used to create meanings for them. The paper implicitly suggests that both a religion's doctrines in theory and the outcome of a complex interaction with the changing society in which the religion is practiced determine its potential to influence animal-human relationships.

From a largely Western phenomenon, the “animal turn” has, in recent years, gone global. Animals and Human Society in Asia: Historical, Cultural and Ethical Perspectives is just such a timely product that testifies to this trend.But why Asia? The editors, in their very helpful overview essay, have from the outset justified the volume's focus on Asia and ensured that this is not simply a matter of lacuna filling. The reasons they set out include: the fact that Asia is the cradle (...) of early human settlement and animal domestication; Asia encompasses an extreme diversity of closely connected ecosystems and human cultures; Asia is the place where the world's major religions originated; and, as in other parts of the world, Asia's use of animals for food and other utilitarian purposes constitutes a prominent feature of its culture. All of these factors, they argue, made Asia a unique lab for the exploration of major developments in human civilization and the complexities of human-animal interactions.Based on these premises, the book is divided into four parts, each concentrating on areas that the editors consider to have paramount significance in world history: Part I, “Hunting and Domestication”; Part II “Animals as Food”; Part III “Animals at War”; and Part IV “Animals in Culture and Religion.” As many good works on animal studies do, the volume adopts a truly cross-disciplinary approach, uniting scholars from disciplines as diverse as archaeology, history, anthropology, art, religion, literature, and cultural studies. It too takes an interregional approach and covers a vast geographical area, stretching from the western edge of Asia in the Levant to Central Asia, where once roamed the horses of the nomadic pastoral tribes, to the other end of Asia, including India, China, and Japan. Temporally impressive as well, the work takes us from the deep history of the Paleolithic period up to the contemporary world, exploring the diverse roles that a wide range of animals—horses, donkeys, camels, elephants, tigers, and so forth—have played in Asia's rich and unique past and present.Strong in archaeology, Part I, “Hunting and Domestication,” responds to the much-called for “deep” or “coevolutionary” history of human-animal relations in recent years. The three chapters discuss, respectively, the roles that proboscideans have played in the diet and culture of early societies in Paleolithic China and beyond; the ways in which animals of all sizes have been increasingly integrated into the diet, daily uses, trade, and warfare in Holocene Negev; and the diversifying roles played by donkeys in the early Bronze Age in Southern Levant as a food source, a means of transport and in ritual sacrifices. Together, they demonstrate, with reference to telling archaeological evidence how the early societies in this region have been highly dependent upon the increasingly sophisticated interactions with and uses of mega-herbivores in the protracted and by no means clear-cut transition from hunting and herding towards the agricultural way of life, affirming the co-existing and co-constituting relations between humans and other animals in the deep past of Asia.The chapters in the section on “Animals at War” equally reveal the crucial roles that animals have played in the military sphere, as either a practical war technology or a show of military power. “Elephants in Mongol History” revisits the thesis of elephant-mounted troops in South and Southeast Asia as a barrier to Mongol expansion. Through its lively account of the pivotal battles in Mongolian history, especially that against India and China, it illustrates with great success the complex interactions between animals (especially elephants, horses, and humans), technology, and the geographical environment, which jointly exercised their influence on the outcome of warfare and degree of success of political rule. Turning away from the dynamic of warfare, the following two chapters explore the biopolitical question of the management of the horse as a bio-resource in the Mamluk Sultanate of Egypt and Syria (1250–1517) and early Ming Dynasty China, respectively. The first one places its focus on the breeding, procurement, and feeding of the horse subjects in question, while the latter concentrates on the human organization of various resources for the upkeep of government horses—a conventional area of study called “horse administration” in the institutional history of the government in China.The last section, “Animals in Culture and Religion,” examines the changing images of apex predators, such as lions and tigers, in Buddhist perceptions from South Asia to East Asia; the cult of the Horse King in late Imperial China; and the significance of animal signs in Mongolian historiography. They represent an established approach in animal studies that seeks to understand different aspects of human culture through symbolic or metaphorical animals. Instead of treating the animals discussed as mere abstractions, which has been a frequent criticism of works that adopt this approach, the relations between the symbolic animals and their prototype in the natural world were attentively explored. The essay on the cult of the Horse King, for example, closely links the wax and wane of the cult since late imperial China with the changing use and subsequent disuse of the actual horses in agriculture, transportation, commerce, and quotidian life. Yet, classic as these essays on symbolic animals are, one does feel slightly unsatiated when coming to the end of this section, which also marks the end of this volume. Having been reminded early in the introductory essay that Asia was “a major site for the emergence of moral teachings and ethical guidance on the treatment of animals” and how this legacy “still affects the lives of billions of humans to this very day,” one feels naturally rather let down that no article in this volume directly addresses this vital ethical dimension, especially since it belongs to a series on “animal ethics.”Indeed, regarding the task of placing either the nonhuman animals or the ethical relations between humans and other animals center stage, the essays in this volume achieve only varying levels of success. Some authors exhibit a more acute awareness of what “animal studies” or “animal ethics” might entail epistemically and methodically and experiment by paying closer attention to the species-specific characteristics, experience, and agency of nonhuman animals in order to cast off the deified anthropocentrism previously ruled in humanist scholarship. However, others have made no such attempt. For example, in Part II of “Animals as Food,” an essay on the production and consumption of milk in contemporary China, albeit alert to the issue of health hazards to consumers, omits any consideration of the subject from the dairy cows’ perspective under the modern intensive farming system. Moreover, otherwise superb research on the tuna-fishing industry in Japan, with its insightful discussion of the nexus between knowledge economies and imperial politics, too passes over any discussion of the fate of the tuna, whether collectively as a group of living organisms containing 15 species or individually as animals with an embodied experience. One does ponder whether these essays would fit better in a volume on the cultural history of food or on the entwining history of knowledge production, economics, and politics, which conventionally position human interests at the center of research.Taken as a whole, this is an impressive volume that directs our attention to the hitherto understudied world of Asia in animal studies. The long durée, with its interdisciplinary and interregional approach, also most powerfully presents a past in Asia that could not have been the same without the participation of animals at every level, from everyday life to the shaping of cultural values, the construction of belief systems, the building of a national identity, and even the rise and fall of regimes. Scholars and students interested in expanding the frontier of our understanding of the world with a more inclusive “we” should find a wealth of interesting subjects on which to build further research. Finally, the volume also presents a fitting occasion for all scholars committed to animal studies to consider the grave challenge confronting the field that arose alongside its growing respectability and rapid expansion: Should it be oriented toward the destabilization of our previously anthropocentric conception of the world? Or should no such perimeter be imposed, as in this volume? The overall breadth and limitations of this volume leave one pondering this issue. (shrink)

Attending cram school has long been a trend in ethnic Chinese culture areas, including Taiwan. Despite the fact that school reform policies have been implemented in Taiwan, cram schools have continued to prosper. Therefore, in this educational culture, how to achieve a good educational effect is also a topic worthy of discussion. However, whether students really engage in those tutoring programs provided by cram schools has seldom been studied. To address this gap, this study explored how parents’ hovering attitude toward (...) life and coursework influences their children’s engagement in cram schools. This study targeted those students who attend English cram schools to test the correlates between two types of helicopter parenting, tutoring engagement and continued attendance at cram schools. A total of 320 questionnaires were sent out, and 300 were returned, giving an overall response rate of 93.75%. Excluding seven incomplete or invalid questionnaires, 293 valid questionnaires were received. The results of this study show that hovering behavior awareness is negatively related to cram school engagement, whereas cram school engagement is positively related to the intention to continue attending cram school. Moreover, the results imply that parents should alleviate their helicoptering behavior to enhance their children’s engagement in cram school tutoring programs. (shrink)

Using firm-level data from the U.S. manufacturing industry, this paper examines the relationship among inventory leanness, structural strategies for supply chains, and the carbon intensities of a firm and its suppliers. We formulate hypotheses on and empirically test whether this internal characteristic and these two structural strategies can influence the intensities of firm-level and supply chain environmental impacts. We examine inventory leanness because it not only reflects a manufacturer’s operational efficiency but also markedly influences manufacturers’ financial performance. We also focus (...) on two closely related structural strategies that can influence the scope and ownership of the supply chain process, resulting in changes in emission allocation and, more importantly, how resources are utilized and shared in a firm. Based on multi-year carbon inventory data from U.S. manufacturing firms, we find that manufacturers with greater inventory leanness and a parsimonious process structure tend to attain lower firm-level and supply chain carbon intensities.

The number of competing-brands changes by new product's entry. The new product introduction is endemic among consumer packaged goods firm and is an integral component of their marketing strategy. As a new product's entry affects markets, there is a pressing need to develop market response model that can adapt to such changes. In this paper, we develop a dynamic model that capture the underlying evolution of the buying behavior associated with the new product. This extends an application of a dynamic (...) linear model, which is used by a number of time series analyses, by allowing the observed dimension to change at some point in time. Our model copes with a problem that dynamic environments entail: changes in parameter over time and changes in the observed dimension. We formulate the model with framework of a state space model. We realize an estimation of the model using modified Kalman filter/fixed interval smoother. We find that new product's entry (1) decreases brand differentiation for existing brands, as indicated by decreasing difference between cross-price elasticities; (2) decreases commodity power for existing brands, as indicated by decreasing trend; and (3) decreases the effect of discount for existing brands, as indicated by a decrease in the magnitude of own-brand price elasticities. The proposed framework is directly applicable to other fields in which the observed dimension might be change, such as economic, bioinformatics, and so forth. (shrink)

Delineation of the subthalamic nuclei on MRI is critical for deep brain stimulation surgery in patients with Parkinson’s disease. We propose this retrospective cohort study for quantitative analysis of MR signal-to-noise ratio, contrast, and signal difference-to-noise ratio of the STN on pre-operative three-dimensional stereotactic MRI in patients with medication-refractory PD. Forty-five consecutive patients with medication-refractory PD who underwent STN-DBS surgery in our hospital from January 2018 to June 2021 were included in this study. All patients had whole-brain 3D MRI, including (...) T2-weighted imaging, T2-weighted fluid-attenuated inversion recovery, and susceptibility-weighted imaging, at 3.0 T scanner for stereotactic navigation. The signal intensities of the STN, corona radiata, and background noise were obtained after placing regions of interest on corresponding structures. Quantitative comparisons of SNR, contrast, and SDNR of the STN between MR pulse sequences, including the T2WI, FLAIR, and SWI. Subgroup analysis regarding patients’ sex, age, and duration of treatment. We used one-way repeated measures analysis of variance for quantitative comparisons of SNR, contrast, and SDNR of the STN between different MR pulse sequences, and we also used the dependent t-test for the post hoc tests. In addition, we used Mann–Whitney U test for subgroup analyses. Both the contrast and SDNR were highest on FLAIR. The SNR was highest on SWI, and both the SNR and SDNR were lowest on T2WI. Subgroup analyses demonstrated significantly lower SDNR on SWI for patients receiving medication treatment for ≥13 years. In conclusion, on 3D stereotactic MRI of medication-refractory PD patients, the contrast and SDNR for the STN are highest on FLAIR, suggesting the optimal delineation of STN on FLAIR. (shrink)
