The process of thermo-mechanical fusing (TMF) is one of the major technological processes in the sewing industry. The quality of the sewing article as a whole depends largely on the effective implementation of this process. The good appearance of the finished product and the preservation of the shapes given during the operation of the product depend on the proper choice of the parameters for the TMF. It is therefore important to carry out research to optimize this process. On the other hand, new and different textile materials (TM) with more complex structure and multicomponent composition have appeared in recent years. This determines the different properties of each TM. Therefore, it is extremely important to conduct numerous preliminary studies and analyses to determine the specific effective values for defining the TMF process for a particular type of TM. This is especially important namely for large-scale companies. In the context of the above, it is of particular interest to study the TMF process for an innovative TM (with complex structure and multicomponent composition) registered with a patent for an invention in recent years. The purpose of the present work is to investigate and analyse the nature of the change in temperature between basic and adhesive TM in TMF of innovative /complex in composition and structure/TM. As a result of the performed research and analysis, a method for establishing continuous feedback with the processed textile materials at TMF has been proposed. The nature of the temperature change of the treated innovative TM has been defined. The relationship between the time for conducting the TMF process and the temperature of the pressing plate for the respective innovative TM has been established.

AbstractChina has made great efforts to alleviate poverty in rural ethnic minority areas and targeted achieving the poverty-alleviation task by the end of 2020. Aba, Ganzi, and Liangshan, three of the poorest ethnic prefectures in Sichuan Province, Southwest China, have all implemented “Internet+” tactics since 2013, which have had the positive effect of increasing family revenues by improving communication infrastructure and encouraging the large-scale use of e-commerce. This paper aims to comprehensively investigate whether “Internet+” tactics play a key role in poverty alleviation in Sichuan’s rural ethnic minority areas and to propose further measures to enhance the efficiency of e-commerce practice. To this end, we conduct an analysis using the framework of classic growth theory and use panel data from 2000 to 2018 to examine the relationship between Communication Infrastructure Investment (CII) and a set of poverty-alleviation indicators, including local GDP growth rate (LGGR), local government revenue (LGR), and per-capita income of residents (PCIR). The results indicate that strengthening CII improves the PCIR and local economic growth, playing a key role in poverty alleviation. However, the stimulation of CII on LGGR and LGR wanes as time passes. More financial and technical actions will be needed to improve the efficiency and quality of current strategies for sustainable development in those areas.

Proactive Health Support (PaHS) is a large-scale intervention in Denmark carried out by registered nurses (RNs) who provide self-management support to people at risk of hospital admission to enhance their health, coping, and quality of life. PaHS is initiated with a face-to-face session followed by telephone conversations. We aimed to explore the start-up sessions, including if and how the relationship between participants and RNs developed at the onset of PaHS. We used an ethnographic design including observations and informal interviews. Data were analyzed using a phenomenological–hermeneutical approach. The study showed that contexts such as hospitals and RNs legitimized the intervention. Face-to-face communication contributed to credibility, just as the same RN throughout the intervention ensured continuity. We conclude that start-up sessions before telephone-based self-management support enable a trust-based relationship between participants and RNs. Continuous contact with the same RNs throughout the session promoted participation in the intervention.

While YouTube has become a dominant actor in the global media system, the relationship between platform, advertisers, and content creators has seen a series of conflicts around the question of monetization. Our paper draws on a critical media industries perspective to investigate the relationship between YouTube’s evolving platform strategies on the one side and content creators’ tactical adaptations on the other. This concerns the search for alternative revenue streams as well as content and referencing optimization seeking to grow audiences and algorithmic visibility. Drawing on an exhaustive sample (n=153.770) of “elite” channels (more than 100.000 subscribers) and their full video history (n=138.340.337), we parse links in video descriptions to investigate the appearance and spread of crowdfunding platforms like Patreon, but also of affiliate links, merchandise stores, or e-commerce websites like Etsy. We analyze the evolution of video length and posting frequency in response to platform policy as well as visibility tactics such as metadata and category optimization, keyword stuffing, or title phrasing. Taken together, these elements provide a broad picture of “industrialization” on YouTube, that is, of the ways creators seek to develop their channels into media businesses. While this contribution cannot replace more qualitative, in-depth research into particular channels or channel groups, we hope to provide a representative picture of YouTube’s elite channels and their quest for visibility and success from their beginnings up to early 2020.

Handling emergency cases must not only be carried out quickly but also must be precise. Standard Operating Procedures (SOP) is one of the instruments to measure the quality of service. the number of patient visits that can affect the quality of service. Triage is a way of sorting patients based on therapy needs and available resources. Therapy is based on ABC conditions (Airway, with cervical spine control, Breathing, and Circulation with bleeding control). On the other hand, the COVID-19 pandemic greatly affects the response time, impacting the number of patient visits. Response time is the time between the beginning of a request being responded to in other words it can be called response time. A good response time for patients is 5 minutes. The purpose of this study was to identify the relationship between the number of patient visits and the accuracy of triage implementation and response time. The electronic database used is PubMed, Springer, and Google Scholar with a search strategy using the PICO (patient, intervention, comparison, and outcome) method.

A vast majority of adults believe that class size reductions are a good way to improve the quality of public schools. Reviews of the research literature, on the other hand, have provided mixed messages on the degree to which class size matters for student achievement. Here I will discuss a substantial, but overlooked, body of experimental work on class size that developed prior to World War II. These field experiments did not have the benefit of modern econometrics, and only a few were done on a reasonably large scale. However, they often used careful empirical designs, and the collective magnitude of this body of work is considerable. Moreover, this research produced little evidence to suggest that students learn more in smaller classes, which stands in contrast to some, though not all, of the most recent work by economists. In this essay, I provide an overview of the scope and breadth of the field experiments in class size conducted prior to World War II, the motivations behind them, and how their experimental designs were crafted to deal with perceived sources of bias. I discuss how one might interpret the findings of these early experimental results alongside more recent research.

AbstractBackgroundPostpartum depression is a major mental health issue. It not only adversely affects the mother's quality of life, but also mother-infant bonding. However, the relationship between postpartum depression (at multiple points after childbirth) and mother-infant bonding failure one year after birth is not well understood. This study investigates the relationship between postpartum depression at 1-month and 6-month after birth and mother-infant bonding failure at 1 year after birth with a large cohort.MethodsData from 83 109 mothers from the Japan Environment and Children's Study were analyzed. Mother-infant bonding 1-year after delivery was assessed using the Mother-to-Infant Bonding Scale Japanese version (MIBS-J). Postpartum depression was measured using the Edinburgh Postnatal Depression Scale (EPDS) at 1-month and 6-month after delivery. Twenty covariates during pregnancy and one month after delivery were controlled for deriving the odds ratios (ORs) describing postpartum depression to mother-infant bonding.ResultsEPDS Total Score crude ORs and adjusted ORs against the MIBS-J Total Score at 1-month and 6-month after delivery were calculated. Crude ORs were 1.111 (95% CI 1.110–1.112) and 1.122 (95% CI 1.121–1.124) respectively. In the fully adjusted model, ORs were 1.088 (95% CI 1.086–1.089) and 1.085 (95% CI 1.083–1.087), respectively.ConclusionsThis study demonstrated prospectively, in a large-scale cohort, that depression at multiple postpartum points, including associations with each EPDS and MIBS-J factors, may be a robust predictor of mother-infant bonding failure 1-year after birth.

This paper raises once more the question of the relationship between philosophy on the one hand and common sense on the other. More particularly, it is concerned with the role which common sense can play in passing judgment on the rational acceptability (or otherwise) of large-scale hypotheses in natural philosophy and the cosmological part of metaphysics. There are, as I see it, three stages through which the relationship has passed in the course of the twentieth century. There is the era of G. E. Moore, the Quine–Feyerabend period, and now a new and modest vindication of common sense is emerging in the work of Jerry Fodor.

Objective. At present, the relationship between autophagosomes and the prognosis of various cancers has become a subject of active investigation. A series of studies have demonstrated the correlation between autophagy microtubule-associated protein light chain 3 (LC-3), Beclin-1, and colorectal cancer (CRC). Since autophagy has dual regulatory roles in tumors, the results of this correlation are also uncertain. Hence, we summarized the relationship between Beclin-1, LC-3, and CRC using systematic reviews and meta-analysis to clarify their prognostic significance in it. Methods. PubMed, EMBASE, Cochrane Library, and Web of Science databases were searched online up to April 1, 2019. The quality of the involving studies was assessed against the Newcastle-Ottawa Scale (NOS). Pooled hazard ratio (HR) and 95% confidence interval (CI) in a fixed or random effects model were used to assess the strength of correlation between Beclin-1, LC-3, and CRC. Results. A total of 9 articles were collected, involving 2,297 patients. Most literatures scored more than 6 points, suggesting that the quality of our including research was acceptable. Our finding suggested that the expression of Beclin-1 was not associated with overall survival (HR = 0.68, 95% CI (0.31–1.52), P=0.351). Nonetheless, LC-3 expression exerted significant impact on OS (HR = 0.51, 95% CI (0.35–0.74), P<0.05). Subgroup analysis exhibited that Beclin-1 expression was associated with OS at TNM stage III (HR = 0.04, 95% CI = 0.02–0.08, P<0.05), surgical treatment (HR = 1.53, 95% CI (1.15–2.02), P=0.003), and comprehensive treatment (HR = 0.27 95% CI (0.08–0.92), P=0.036), respectively. Similarly, the results showed the increased LC-3 expression in CRC was related to OS in multivariate analyses (HR = 0.44, 95% CI (0.34–0.57), P<0.05), stages (HR = 0.51, 95% CI (0.35–0.74), P<0.05), and comprehensive treatment (HR = 0.44, 95% CI (0.34–0.57), P<0.05). Conclusions. Autophagy-related proteins of LC-3 might be an important marker of CRC progression. However, since the number of the original studies was limited, more well-designed, large-scale, high-quality studies are warranted to provide more convincing and reliable information.

Using egocentric network data from the University of California Social Networks Study (1,136 respondents; 11,536 alters), this study examines how difficult ties—an unexplored form of social negativity—are associated with well-being. Findings show that well-being is affected by the quality of the relationship rather than its presence in the network. Having a nondifficult partner is associated with lower loneliness compared to having no partner, but having no partner and having a difficult partner are related to similar levels of loneliness. Likewise, having difficult adult children and having no adult children are associated with reporting greater psychological distress than having nondifficult adult children. Consistent with the stress process model, the negative association of a difficult partner with well-being is buffered when that partner is otherwise supportive and when the other ties in the network are supportive. However, that association is amplified when the other ties are also difficult.
