Emerging from the shadows: Trends in HIV ambulatory care, viral load testing, and viral suppression in a U.S. HIV cohort, 2019-2022: Impact of COVID-19 pandemic.

This article aimed at analyzing the acute impact and the longer-term recovery of COVID-19 pandemic effects on clinical encounter types, HIV viral load (VL) testing, and suppression (HIV VL < 200 copies/mL). This study was a longitudinal cohort study of participants seen during 2019-2022 at nine HIV Outpatient Study (HOPS) sites. Generalized linear mixed models (GLMMs) estimated monthly rates of all encounters, office and telemedicine visits, and HIV VL tests using 2010-2022 data. We examined factors associated with nonsuppressed VL (VL ≥ 200 copies/mL) and not having ambulatory care visits during the pandemic using GLMM for logistic regression with 2017-2022 and 2019-2022 data, respectively. Of 2351 active participants, 76.0% were male, 57.6% aged ≥ 50 years, 40.7% non-Hispanic White, 38.2% non-Hispanic Black, 17.3% Hispanic/Latino, and 51.0% publicly insured. The monthly rates of in-person and telemedicine visits varied during 2020 through mid-year 2022. Multivariable logistic regression showed that persons with no encounters were more likely to be male or have VL ≥ 200 copies/mL. For participants with ≥1 VL test, the prevalence rate of HIV VL ≥ 200 copies/mL during 2020 was close to the rates from 2014 to 2019. The change in probability of viral suppression was not associated with participant's age, sex, race/ethnicity, or insurance type. In the HOPS, overall patient encounters declined over 2 years during the pandemic with variations in telemedicine and in-person events, with relative maintenance of viral suppression. Ongoing recovery from the impact of COVID-19 on ambulatory care will require continued efforts to improve retention and patient access to medical services.

Secondary Ethnic Effects in the Transition to Higher Education in Germany and Their Explanations

Given their lower socioeconomic background and achievement, immigrants and their descendants have been shown to make more ambitious decisions regarding educational transitions. While previous research has extensively analysed transitions within and after compulsory education, research on late transitions is scarce. This study focuses on the secondary effect of ethnic origin in the transition after upper secondary education in Germany, where school leavers decide between vocational education and training and higher education. Based on longitudinal data from the National Educational Panel Study, we first analyse differences by ethnic origin (Turkey, former Soviet Union, Poland, other countries) and immigrant generation (first, second, third generation) net of socioeconomic background and achievement. Compared to those of the ethnic majority, we find increased probabilities of enrolment in higher education for most ethnic groups of the first and second immigrant generation, net of differences in socioeconomic background and achievement. Second, we test four explanatory approaches for secondary ethnic effects (immigrant optimism, relative status maintenance, anticipated discrimination, and information deficits). By employing decomposition analyses for nonlinear regression models, we find that, taken together, the four explanations account for up to half of the ethnic differences in educational choice after upper secondary education. Specifically, increased levels of immigrant optimism and information deficits regarding vocational education explain a substantial share of the ethnic differences among all origin groups. For Turkish immigrants, the motive to maintain relative status in the origin country also contributes to increased enrolment rates in higher education.

Are there cross-cultural differences in the transformation of motivation process in close relationships?

When faced with an undesirable behavior by one’s partner, theories of relationship maintenance indicate that individuals must undergo a transformation of motivation in order to set aside their initial impulse to respond in a self-centered manner, and instead choose to respond in a pro-relationship manner. However, the cultural psychology literature indicates that a primary focus on one’s own needs and goals is predominantly a feature of individualistic cultures, such as those in the Unites States and Western Europe which have been the setting for the vast majority of close relationships research. Thus, it is possible that people from less individualistic cultural contexts do not experience this same transformation of motivation process when faced with an undesirable behavior by their partner, because their initial impulse is less self-centered and more other- or relationship-centered. To test this hypothesis we conducted pre-registered replications of two classic studies documenting the transformation of motivation process (Yovetich &amp; Rusbult, 1994) using a cross-cultural sample of participants from the U.S. and Thailand. The extent to which people in both cultural settings engaged in the transformation of motivation process was assessed in a correlational study ( N = 187) and an experimental study ( N = 328) of partnered individuals. Results indicate that participants in both cultural contexts experience a transformation of motivation process, and the magnitude of the transformation did not differ between the two countries. Exploratory analyses indicate that Thai participants engaged in more passive behaviors than U.S. participants, and U.S. participants thought passive behaviors were more harmful than active behaviors. Overall, when faced with an unpleasant behavior by one’s partner, the need to set aside one’s initial impulse in order to respond in a more pro-relationship manner appears universal, but the exact behaviors that are the endpoint of that process differ across cultures.

A DNA tetrahedron-based nanosuit for efficient delivery of amifostine and multi-organ radioprotection

Unnecessary exposure to ionizing radiation (IR) often causes acute and chronic oxidative damages to normal cells and organs, leading to serious physiological and even life-threatening consequences. Amifostine (AMF) is a validated radioprotectant extensively applied in radiation and chemotherapy medicine, but the short half-life limits its bioavailability and clinical applications, remaining as a great challenge to be addressed. DNA-assembled nanostructures especially the tetrahedral framework nucleic acids (tFNAs) are promising nanocarriers with preeminent biosafety, low biotoxicity, and high transport efficiency. The tFNAs also have a relative long-term maintenance for structural stability and excellent endocytosis capacity. We therefore synthesized a tFNA-based delivery system of AMF for multi-organ radioprotection (tFNAs@AMF, also termed nanosuit). By establishing the mice models of accidental total body irradiation (TBI) and radiotherapy model of Lewis lung cancer, we demonstrated that the nanosuit could shield normal cells from IR-induced DNA damage by regulating the molecular biomarkers of anti-apoptosis and anti-oxidative stress. In the accidental total body irradiation (TBI) mice model, the nanosuit pretreated mice exhibited satisfactory alteration of superoxide dismutase (SOD) activities and malondialdehyde (MDA) contents, and functional recovery of hematopoietic system, reducing IR-induced pathological damages of multi-organ and safeguarding mice from lethal radiation. More importantly, the nanosuit showed a selective radioprotection of the normal organs without interferences of tumor control in the radiotherapy model of Lewis lung cancer. Based on a conveniently available DNA tetrahedron-based nanocarrier, this work presents a high-efficiency delivery system of AMF with the prolonged half-life and enhanced radioprotection for multi-organs. Such nanosuit pioneers a promising strategy with great clinical translation potential for radioactivity protection.

Exploring the Dynamics of Miscommunication between Arabic and English in Economic Discourse

The main goal of this study is to gain a comprehensive understanding of the complex and diverse dynamics of miscommunication that occur during economic discussions between Arabic and English languages. By exploring this topic, the study aims to shed light on important questions about the origins of these misunderstandings and their effects on economic interactions. To achieve this objective, the research will draw upon valuable insights from previous agreements, intercultural bargaining, and global economic relations. It is crucial to emphasize that economic misunderstandings in conversations arise from various factors, including differences in language structure, disparities in cultural backgrounds, and varying contexts. These elements contribute to the confusion surrounding economic terminology, such as sentence structure, vocabulary and meaning difficulties, and contrasting communication styles. The research also examines the influence of cultural nuances and investigates how past events, cultural practices, and societal legacies shape the understanding of economic terms. The importance of effective communication in promoting trust and facilitating successful economic collaboration cannot be overstated. It goes beyond the economic implications of unfavorable trade terms and strained international relations. This research delves into the challenges faced by interpreters and negotiators, highlighting how technology can either alleviate or exacerbate the issue of miscommunication. Ultimately, it serves as a reminder that managers' misunderstandings play a pivotal role in economic dialogues. In today's interconnected global economy, clear and precise communication is essential for productive negotiations and the maintenance of long-lasting international business relationships. To address this, we propose proactive measures such as supporting training programs, leveraging technology wisely, and demonstrating a strong commitment to intercultural communication. The study underscores the significance of adopting effective communication strategies to navigate complex economic conversations and uphold harmonious global economic relationships in an ever-changing world.

The interrelationship among trust, cooperativity and reliability: an analysis of doctor-patient interaction

Trust-related issues have attracted much attention from researchers recently. In the studies on trust, little attention has been paid to its interrelations with cooperativity and reliability. This paper sheds light on the relationship among trust, cooperation, and reliability in a medical context. Through a discourse analysis of the conversations between doctors and patients (including the patients’ relatives) in China, this paper finds that: (i) cooperativity will not directly lead to trust in a medical context; (ii) being cooperative or using strategies to disclaim responsibility will lead to high reliability and will indirectly construct trust; (iii) reliability is a premise for trust in the medical context, and it can be repaired through rapport management strategies, such as empathy discourse if that reliability has been broken down. The research findings in this paper possess both theoretical and practical significance because they will refresh our understanding of the interrelationship among trust, cooperation, and reliability and contribute to the maintenance or enhancement of trust relations between doctors and patients.

Studies of Protein Binding to Biomimetic Membranes Using a Group of Uniform Materials Based on Organic Salts Derived From 8-Anilino-1-naphthalenesulfonic Acid.

Tuning the 8-anilino-1-naphthalenesulfonic acid (ANS) structure usually requires harsh conditions and long reaction times, which can result in low yields. Herein, ANS was modified to form an ANS group of uniform materials based on organic salts (GUMBOS), prepared with simple metathesis reactions and distinct cations, namely tetrabutylammonium (N4444), tetrahexylammonium (N6666), and tetrabutylphosphonium (P4444). These ANS-based GUMBOS were investigated as fluorescent probes for membrane binding studies with four proteins having distinct physicochemical properties. Liposomes of 1,2-dimyristoyl-sn-glycero-3-phosphocholine were employed as membrane models as a result of their ability to mimic the structure and chemical composition of cell membranes. Changes in fluorescence intensity were used to monitor protein binding to liposomes, and adsorption data were fitted to a Freundlich-like isotherm. It was determined that [N4444][ANS] and [P4444][ANS] GUMBOS have enhanced optical properties and lipophilicity as compared to parent ANS. As a result, these two GUMBOS were selected for subsequent protein-membrane binding studies. Both [N4444][ANS] and [P4444][ANS] GUMBOS and parent ANS independently reached membrane saturation within the same concentration range. Furthermore, distinct fluorescence responses were observed upon the addition of proteins to each probe, which demonstrates the impact of properties such as lipophilicity on the binding process. The relative maintenance of binding cooperativity and maximum fluorescence intensity suggests that proteins compete with ANS-based probes for the same membrane binding sites. Finally, this GUMBOS-based approach is simple, rapid, and involves relatively small amounts of reagents, making it attractive for high-throughput purposes. These results presented herein can also provide relevant information for designing GUMBOS with ameliorated properties.

‘From divided past to cohesive future’: a reflection on the reconciliatory mechanisms of (Yoruba) traditional approaches to conflict resolution in Nigeria

ABSTRACT Traditional conflict resolution mechanisms in Nigeria are deeply rooted in customs, traditions, and native laws, forming a complex network that dispenses justice. Among these mechanisms, the reconciliation process stands out as a crucial traditional instrument, encompassing the pursuit of truth, justice, healing, and forgiveness. This study focuses on the Yoruba indigenous system and examines how its reconciliatory mechanisms contribute to conflict resolution through traditional reconciliation processes and in the healing of emotional wounds. Using qualitative research methods, this study generated data using interview protocols such as key informant interviews (KII) and naturalistic observational studies. This study explores the significance of indigenous practices in the reconciliation process within the Yoruba traditional society. These indigenous practices are employed to mend broken relationships and bridge the gaps created by conflicts. It further emphasizes that traditional conflict resolution approaches among the Yoruba ethnic group primarily serve the purposes of genuine reconciliation, peacebuilding, and maintenance of social relationships. This research confirms the appropriateness and practicality of Yoruba's traditional conflict resolution mechanisms as an effective home-grown approach. This demonstrates their compatibility with the modern Nigerian system, offering a pathway towards a cohesive future characterized by harmonious relationships.

Examining the Ethical Considerations of Placing Elderly Parents in Nursing Homes: A Perspective on Maqasid Sharia and Social Welfare

The objective of this study is to examine the legal status of parental care in juvenile homes, which continues to be a source of contention within the community. Some view the act as an act of disobedience, while others view it from a different perspective. The theoretical framework employed to investigate this issue is the theory maqasid sharia. The rationale for this approach is that it is considered to be a relevant methodology, and no other research has been identified that employs this theory. This type of research is normative legal research, which involves the examination of primary legal materials pertinent to the research. The results of this study indicate that entrusting parents to juvenile homes does not necessarily imply a rupture in the relationship between children and parents. Instead, it allows for the maintenance of positive relations with parents while avoiding the negative consequences of neglecting them. Consequently, this study aligns with maqasid sharia including the protection of parents' lives (hifz al-nafs), enabling parents to focus on worship (hifz al-Din) safeguarding against negative thoughts between them (hifz al-�aql), pertains to the avoidance of children doing wrong if they gather in the same house (hifz al-Nasl) and encompasses the maintenance of good relations between parents and children as an asset (hifdz al-mal). The results of this study are undoubtedly contentious, particularly when viewed through the lens of divergent trends. Nevertheless, the findings of this study can serve as a reference point to prevent the immediate assumption of unfaithfulness in children who leave their parents in nursing homes.

Making “settler time”: how mineral exploration finance circumscribes Indigenous resistance

This essay considers the relationship between exploration finance and the reproduction and maintenance of colonial land relations in Canada. Drawing on research examining the capitalization of exploration across Anishinaabe, Anishini, and Cree homelands in Ontario’s far north, I consider the significance of “flow-though” and royalty-financing techniques as essential to the sector’s liquidity. These techniques circumscribe Indigenous resistance in order to protect investor capital and contribute to a system of securities regulation that operationalizes certainty.

Structural underpinnings and long-term effects of resilience in Parkinson’s disease

Resilience in neuroscience generally refers to an individual’s capacity to counteract the adverse effects of a neuropathological condition. While resilience mechanisms in Alzheimer’s disease are well-investigated, knowledge regarding its quantification, neurobiological underpinnings, network adaptations, and long-term effects in Parkinson’s disease is limited. Our study involved 151 Parkinson’s patients from the Parkinson’s Progression Marker Initiative Database with available Magnetic Resonance Imaging, Dopamine Transporter Single-Photon Emission Computed Tomography scans, and clinical information. We used an improved prediction model linking neuropathology to symptom severity to estimate individual resilience levels. Higher resilience levels were associated with a more active lifestyle, increased grey matter volume in motor-associated regions, a distinct structural connectivity network and maintenance of relative motor functioning for up to a decade. Overall, the results indicate that relative maintenance of motor function in Parkinson’s patients may be associated with greater neuronal substrate, allowing higher tolerance against neurodegenerative processes through dynamic network restructuring.

ХАРАКТЕРИСТИКА ЧИННИКІВ, ЯКІ ВПЛИВАЮТЬ НА МАРКЕТИНГОВІ ВЗАЄМОВІДНОСИНИ ТА КОНКУРЕНТУ МАРКЕТИНГОВУ СТРАТЕГІЮ

The article is devoted to the characteristics of factors that affect marketing relationships and competitive marketing strategy. Every day, companies face the issue of paying close attention to the factors that affect marketing communication with the client, the formation of competitive advantages in the market, and the development of such a marketing strategy that would provide the company with a leading position in the market. The article defines the main principles of marketing relationships that underlie the marketing competitive strategy. If a company builds relationships with a customer based on these principles, the overall company wins, because this approach helps increase customer satisfaction, increase their trust in the brand, and reduce customer churn. The main types of marketing strategies used by companies in the market are defined: cost leadership strategy, differentiation strategy, focus strategy, aggressive strategy, defense strategy. In general, a marketing strategy is a plan of action developed by a company to ensure its competitive advantage in the market. The listed types of competitive marketing strategies prove that the choice of a competitive marketing strategy depends on many factors, such as the size of the company, its resources, market position, characteristics of the target audience and the actions of competitors. The classification of influencing factors aimed at the formation and maintenance of longterm relations between the company and clients has been carried out. Such factors are defined as: product or service quality, value for the client, satisfaction of the client's needs and expectations, communication, client service, trust and reputation, loyalty, technologies. Having analyzed the factors influencing marketing relationships and the competitor's marketing strategy, attention is focused on their positive impact on the company's activities. Keywords: marketing, marketing relationships, marketing strategies, influencing factors, company, strategy

Configuring the digital relationship landscape: a feminist new materialist analysis of a couple relationship app

Digital technologies play an increasing role in intimate couple relationships, prompting new approaches to better understand the contemporary digital relationship landscape. This article uses feminist new materialist assemblage thinking to explore the functioning and processes of a relationship support app, Paired. Deploying diffractive analysis, it presents three composite narratives that explore the temporality of couple relationships, relationship work and situated practices of coupledom. Composite narratives retain the emotional truth of original accounts through combined participant voices, enabling attention to be focused on the user–relationship–app assemblage. Findings suggest that routinised app notifications prompt meaningful everyday relationship maintenance behaviours. Human–technology intra-actions thus generate positive relationship health and wellbeing behaviours which may have lasting benefits. This article’s contributions are therefore largely methodological and conceptual, with analysis of supplementary primary interview data (n=20) derived from a mixed-methods evaluation, including brief longitudinal surveys over three months (n=440) and a detailed survey (n=745).

Examining the trajectory of relational conflict leading up to and after an anticipated stressor

AbstractA wealth of research suggests that as stress increases, so does conflict in close relationships. But is this always the case? Specifically, how does the trajectory of conflict unfold in the period before and after an acute and anticipated major life stressor? We capitalize on a 44‐day dyadic diary where one partner was preparing for the New York State Bar Exam (N = 312 couples) to explore the trajectory of conflict leading up to the exam, as well as how these patterns differed once exams finished. Results revealed that examinees and partners reported statistically meaningful decreases in conflict as exams approached, which contrasts prior research. This was followed by a spike in the likelihood of conflict immediately after exams were finished, and a quick return to low likelihoods of conflict one week after exams. This work highlights how couples, even in the face of stress, regulate their emotions and engage in relationship maintenance processes. However, relationship frustrations tend to be expressed—resulting in conflict—once the stressor is over. Not only does this work inform theories about relational conflict during times of stress, but it also highlights the need to study the dynamics of stress before, during, and after meaningful life events.

Alpha lipoic acid mitigates adverse impacts of drought stress on growth and yield of mungbean: photosynthetic pigments, and antioxidative defense mechanism.

Exogenous use of potential organic compounds through different modes is a promising strategy for the induction of water stress tolerance in crop plants for better yield. The present study aimed to explore the potential role of alpha-lipoic acid (ALA) in inducing water stress tolerance in mungbean lines when applied exogenously through various modes. The experiment was conducted in a field with a split-plot arrangement, having three replicates for each treatment. Two irrigation regimes, including normal and reduced irrigation, were applied. The plants allocated to reduced irrigation were watered only at the reproductive stage. Three levels of ALA (0, 0.1, 0.15 mM) were applied through different modes (seed priming, foliar or priming+foliar). ALA treatment through different modes manifested higher growth under reduced irrigation (water stress) and normal irrigation. Compared to the other two modes, the application of ALA as seed priming was found more effective in ameliorating the adverse impacts of water stress on growth and yield associated with their better content of leaf photosynthetic pigments, maintenance of plant water relations, levels of non-enzymatic antioxidants, improved activities of enzymatic antioxidants, and decreased lipid peroxidation and H2O2 levels. The maximum increase in shoot fresh weight (29% and 28%), shoot dry weight (27% and 24%), 100-grain weight (24% and 23%) and total grain yield (20% and 21%) in water-stressed mungbean plants of line 16003 and 16004, respectively, was recorded due to ALA seed priming than other modes of applications. Conclusively, 0.1 and 0.15 mM levels of ALA as seed priming were found to reduce the adverse impact of water stress on mungbean yield that was associated with improved physio-biochemical mechanisms. The findings of the study will be helpful for the agriculturalists working in arid and semi-arid regions to obtain a better yield of mungbean that will be helpful to fulfill the food demand in those areas to some extent.

Romantic partner communication, familism values, and Latine young adults’ relationship maintenance

Negative communication between partners can impede the enactment of prosocial, relationship maintenance behaviors. These processes are especially critical to consider for Latine young adults who hold cultural values, like familism, which emphasize the great importance of personal relationships. Using a sample of 475 Latine young adults ( M = 24.8 years, SD = 3.22), we examined the moderating role of familism on the association between negative communication (e.g., partners’ propensity to withdraw or criticize during interactions) and relationship maintenance (e.g., affectionate and supportive efforts to sustain the relationship). We found that negative communication was inversely associated with individuals’ own relationship maintenance enactment. However, familism buffered the association between negative communication and relationship maintenance; under conditions of high familism, the association between negative communication and relationship maintenance remained negative, but with a weaker effect than under conditions of low familism. Findings reinforce the negative effects of maladaptive communication in relationships more broadly and highlight the protective role of relationally oriented cultural values.

The Impact of Educational Environment and Educational Strategies on Adolescents' Interpersonal Relationships

In modern society, interpersonal relationships at the adolescent stage not only have a profound impact on the development of an individual's social skills but also play a key role in his or her future career, family and social life. With the increasing research in education and psychology, adolescents' interpersonal relationship development has become a focus of attention in the fields of education and mental health. The impact of teaching and learning environments and educational strategies on adolescents' social skills and emotional development has become more pronounced, especially in an increasingly complex and diverse society. Therefore, an in-depth exploration of this topic is important for developing more effective educational policies and fostering good interpersonal relationships among adolescents. This paper analyzes in depth the influence of educational environment and educational strategies on the interpersonal development of adolescents, and through a comparative analysis of previous studies, the author finds that the creation of an open and positive educational environment has a positive influence on the promotion of the development of adolescent interpersonal relationships. Educational strategies of cooperation, communication, and content diversity play an important role in adolescents' maintenance of interpersonal relationships. The paper also points out that while existing research provides valuable insights, further research is needed on other factors that may influence adolescents' interpersonal development. The paper concludes with some recommendations for educators and policymakers aimed at creating more effective teaching and learning environments and strategies to promote healthy interpersonal relationship development among adolescents.

Comparative Transcriptomics of Fat Bodies between Symbiotic and Quasi-Aposymbiotic Adult Females of Blattella germanica with Emphasis on the Metabolic Integration with Its Endosymbiont Blattabacterium and Its Immune System.

We explored the metabolic integration of Blattella germanica and its obligate endosymbiont Blattabacterium cuenoti by the transcriptomic analysis of the fat body of quasi-aposymbiotic cockroaches, where the endosymbionts were almost entirely removed with rifampicin. Fat bodies from quasi-aposymbiotic insects displayed large differences in gene expression compared to controls. In quasi-aposymbionts, the metabolism of phenylalanine and tyrosine involved in cuticle sclerotization and pigmentation increased drastically to compensate for the deficiency in the biosynthesis of these amino acids by the endosymbionts. On the other hand, the uricolytic pathway and the biosynthesis of uric acid were severely decreased, probably because the reduced population of endosymbionts was unable to metabolize urea to ammonia. Metabolite transporters that could be involved in the endosymbiosis process were identified. Immune system and antimicrobial peptide (AMP) gene expression was also reduced in quasi-aposymbionts, genes encoding peptidoglycan-recognition proteins, which may provide clues for the maintenance of the symbiotic relationship, as well as three AMP genes whose involvement in the symbiotic relationship will require additional analysis. Finally, a search for AMP-like factors that could be involved in controlling the endosymbiont identified two orphan genes encoding proteins smaller than 200 amino acids underexpressed in quasi-aposymbionts, suggesting a role in the host-endosymbiont relationship.

Comparison of teaching methods for the emergence and maintenance of untaught relations in foreign language vocabulary acquisition: A systematic replication.

In a replication of Daly and K. Dounavi (2020), the researchers evaluated the effect of foreign tact and bidirectional intraverbal teaching on the emergence of untaught relations. Three university students learned three stimulus sets through three types of teaching: native-foreign intraverbal teaching (vocalizing Spanish words that refer to a Japanese textual stimulus), foreign-native intraverbal teaching (reversed relation of native-foreign condition), and foreign-tact teaching (tacting a picture in Spanish). The researchers used an adapted alternating-treatments design to assess the differential effect of each teaching condition on the emergence of untaught relations in a foreign language and collected data on response maintenance. The results replicated previous findings that native-foreign intraverbal and foreign-tact teachings were more effective than foreign-native intraverbal teaching despite previous reporting that the maintenance outcomes may be a result of carryover effects.

Analysis of Logistics Customer Complaints Based on Grounded Theory

With the rapid development of e-commerce and the continuous expansion of the global market, the logistics industry is facing increasingly complex challenges in meeting consumer demand and improving service quality. In such a competitive environment, customer complaints have become one of the important indicators to evaluate the quality of logistics services and relationship maintenance. Customer complaints not only reflect customer dissatisfaction with the service, but may also hint at potential systemic problems and opportunities for improvement. In order to better improve logistics services, it is necessary to find the direction of logistics improvement through customer complaints. Based on this, we use the grounded theory method to encode and analyze the customer's online comments on the express service, and then get the logical relationship of each category, refine and summarize the causes of customer complaints, and finally get the customer complaint points. The results show that customer complaints mainly focus on the problems of unclear object status, inefficient logistics business, low staff quality and difficult customer intervention.
