This research examined the impacts of diversified income from trading caterpillar fungus on pastoral households' livestock production and income. The specific objectives were to identify the main factors underlying participation in caterpillar fungus trade and to explore the impacts of a diversified income from trading fungus on livestock production activities and income.

Data were collected from a pastoral household survey (n = 503) in five Tibetan Autonomous Prefectures. The authors employed propensity score matching (PSM) procedures to estimate the effects of participation in trading caterpillar fungus.

Pastoral households participating in caterpillar fungus activities maintain smaller herds, sell fewer animals for profit, slaughter more livestock for family consumption and experience fewer livestock deaths compared to nonparticipants. There is also some evidence that pastoral households participating in caterpillar fungus activities have a higher annual income compared to nonparticipants.

A direct measure of grassland degradation was not included due to the data limitation. The estimated average treatment effects could differ under different observed households' characteristics.

This study fills a gap in the literature on the impacts of diversified income on livestock production activities. The authors provide a new perspective on the controversy over the extraction of caterpillar fungus. This study contributes to exploring the dual role of income diversification in addressing poverty and grassland resource degradation for Tibetan pastoral communities.

The purpose of this paper is to examine the impacts of farmland renting-in on planted grain acreage.

A survey data of five counties were analyzed with the two-stage ordinary least squares model.

Households renting-in land trended to plant more maize, and the more land was rented by a household the more maize was planted, while wheat acreage showed non-response to farmland renting-in.

Overall, the analysis suggests that policy makers should be prepared for different changing trends of grain crop acreage across the nation as farmland transfer continues. Future research should pay attention to the effect of farmland transfer on agricultural productivity and rural household income growth.

As the Chinese Government is promoting larger-scale and more mechanized farms as a way of protecting grain security, it is important to understand whether farmland renting-in will reduce planted grain acreage. This study provides empirical evidence showing the answer to that question may differ across different regions and depend on the particular grain crop in question.

The purpose of this paper is to examine the adverse selection in participation in the New Rural Cooperative Medical Scheme (NRCMS), as well as in outpatient and inpatient service utilization, in Chaoyang, Beijing, China.

Probit model is established to test whether the rural Hukou family member in Combined Household (CH) is statistically different from the Pure Rural Household (PRH) in enrollment in NRCMS. Seemingly Unrelated Regression (SUR) model is adopted to examine the difference in the utilization of outpatient and inpatient between the rural Hukou family members in the two kinds of households.

This paper finds that the rural Hukou family member in CH has more probability to enroll in NRCMS than the counterpart in PRH. In the period of six months, the rural Hukou family member in CH exceeds PRH by 0.73 times in outpatient visit number per capita. The former average spends yuan 157 more in outpatient service and is reimbursed yuan 53 more from NRCMS than the latter. Moreover, on average, rural Hukou family member has no difference in the inpatient service utilization between the two kinds of households in the period of 12 months.

This is the first study to empirically test the adverse selection in China's medical insurance market from the perspective of two different types of households, which are CH and PRH.

Visitor center plays an important role in the normal operation and sustainable development of scenic spots, especially as a portal image of its management. This paper presents resilience theory for visitor centers to identify some common issues in designing visitor centers in China scenic spots, including the lack of function, loss of architectural characteristics, and difficultly in adapting to changes in the number of visitors with periodic variations. The framework of resilience theory was set from four dimensions, namely, resilience and match in the composition of ontology function, the extended function, integration of buildings into the surrounding environment, and alternative construction technologies and materials. This theory was explained and analyzed with the application of the theory in practice in combination with the design of Mount Hua visitor center. Results showed that resilience theory yields good application effect.

The present article presents a first‐look into the hired‐labor market in Chinese household farms using data from a national household survey conducted by the Research Center for the Rural Economy (RCRE) at China's Ministry of Agriculture. More specifically, the purpose of this paper is to evaluate the scale and dispersion of China's farm‐household hired laborers among 15 commodities, and test whether market factors influence labor‐hiring decisions – an expectation of a well‐functioning labor market. This research contributes to the literature concerned with the labor constraints facing Chinese household farms, especially those producing seasonal commodities.

An econometric approach is employed to assess whether Chinese farms that hire labor are responding to market factors using two repeated cross‐sections (2006, 2007) of household survey data collected by the Research Center for Rural Economy at China's Ministry of Agriculture.

The paper finds hired labor use on very small‐scale farms is surprisingly prevalent, in contrast to previously published data. The regression results suggest that labor hiring by Chinese farm households, irrespective of farm size, responds strongly to market signals and resource constraints – more labor will be hired when the wage is lower, when output is higher, and among families with fewer family members available to farm work. And the response is particularly robust for wheat, rice, and maize, whose prices are predominant determinants of the food price index.

This paper is limited in its time‐series dimension and data availability. Despite those limitations, the results hold implications for further understanding China's nascent labor market and the level to which market factors have impacted rural farm households.

Focusing on the as‐of‐yet unstudied market for hired labor on Chinese household farms, the present article makes a contribution by showing that hiring of labor in Chinese agriculture is much more prevalent than previously thought. It suggests that Chinese farm‐households are responding to certain labor‐market factors and that the household response does not weaken as the largest farms are omitted from the model, suggesting that even small farms are heeding market signals.

The purpose of this study is to explore the relationship between migration, remittances and agricultural productivity by applying the new economics of labor migration model in the context of north‐west China. The specific objectives are to examine the impacts of rural out‐migration on agricultural productivity in various farming systems, and whether remittances have been reinvested in agriculture.

Cross‐sectional household survey data from three townships were analyzed with the three‐stage least squares (3SLS) regression model.

In multi‐cropping small farming systems, at least in the short run, the loss resulting from losing family labour on lower‐return grain crop production is likely to be offset by the gain from investing in capital‐intensive and profitable cash crop production.

This study provides empirical evidence for the MELM theory. It expands Taylor et al.'s studies by comparing investment behavior and production choices among multiple farm activities, and enriches previous studies by showing that the relation between remittances and agricultural investment depends on the farm activities' profitability.

The purpose of this paper is to establish an accurate model to quantify the effect of conductor roughness on insertion loss (IL) and provide improved measurements and suggestions for manufacturing good conductive copper lines of printed circuit board.

To practically investigates the modified model of conductor roughness, three different kinds of alternate oxidation treatments were used to provide transmission lines with different roughness. The IL results were measured by a vector net analyzer for comparisons with the modified model results.

An accurate model, with only a 1.8% deviation on average from the measured values, is established. Compared with other models, the modified model is more reliable in industrial manufacturing.

This paper introduces the influence of tiny roughness structures on IL. Besides, this paper discusses the effect of current distribution on IL.

This study aims to examine the causal and reciprocal relationships between participation in travel and recreational activities and depression alleviation among survivors of traumatic events. It seeks to uncover the transformative potential of these activities as nonpharmacological interventions and to provide insights that inform the therapeutic design of travel in rehabilitation contexts.

Using a longitudinal dataset, this study employs the random intercept cross-lagged panel model – a robust technique for evaluating causal relationships in nonexperimental longitudinal research – to assess the reciprocal effects between travel and recreation participation and depression severity over time.

Individuals with more severe depression are more likely to engage in travel as a coping mechanism. However, travel does not inherently alleviate depressive symptoms, likely because its physical and emotional demands often outweigh its benefits. This highlights the need to transform travel into structured interventions to maximize therapeutic potential. In contrast, recreational activities exhibit a stronger therapeutic effect, with early participation reducing depressive symptoms and lower depression levels, subsequently encouraging continued engagement in recreation over time.

By highlighting the interplay between social causation and social withdrawal theories, this research proposes transforming travel experiences into structured therapeutic interventions, pioneering a new perspective on integrating health and tourism studies. The study encourages researchers to adopt a holistic approach to understanding the health benefits of travel, considering both the influence of external factors on health and how individuals respond to their psychological state.

本研究旨在深入探讨创伤事件幸存者参与旅行与娱乐活动与抑郁症状缓解之间的因果和相互作用关系, 旨在揭示这些活动作为非药物干预的潜在疗效, 并为康复场景下旅行的治疗性设计提供理论依据和实践参考。

本研究利用纵向数据集, 采用随机截距交叉滞后面板模型（RI-CLPM）进行分析。该方法是一种适用于非实验性纵向研究的模型工具, 能够有效评估旅行与娱乐活动参与和抑郁严重程度之间的双向动态影响。

研究发现, 抑郁程度较高的个体更倾向于将旅行作为一种应对机制。然而, 由于旅行活动的身体与情感成本通常超过其潜在收益, 旅行本身并未显著缓解抑郁症状。这表明, 需要将旅行体验转化为结构化的治疗干预, 以充分发挥其潜在价值。相较而言, 娱乐活动表现出更显著的治疗作用。早期参与娱乐活动能够有效降低抑郁症状, 而抑郁水平的降低反过来又会激励个体持续参与娱乐活动, 从而形成良性循环。

本研究通过结合社会因果理论和社会退缩理论, 提出了有必要将旅行体验转化为结构化治疗干预的新视角, 为健康与旅游研究的整合提供了新的理论创新路径。同时, 本研究倡导从整体视角理解旅行的健康益处, 兼顾外部环境对健康的影响以及个体心理状态对行为的反馈作用, 为未来研究提供了重要启示。

Este estudio tiene como objetivo examinar las relaciones causales y recíprocas entre la participación en actividades de viaje y recreación y el alivio de la depresión entre los sobrevivientes de eventos traumáticos. Busca descubrir el potencial transformador de estas actividades como intervenciones no farmacológicas y proporcionar ideas que informen el diseño terapéutico de viajes en contextos de rehabilitación.

Utilizando un conjunto de datos longitudinales, este estudio emplea el Modelo de Panel Cruzado con Intercepto Aleatorio (RI-CLPM), una técnica robusta para evaluar relaciones causales en investigaciones longitudinales no experimentales, para analizar los efectos recíprocos entre la participación en viajes y recreación y la gravedad de la depresión a lo largo del tiempo.

Las personas con depresión más severa tienden a participar en viajes como mecanismo de afrontamiento. Sin embargo, el viaje en sí no alivia inherentemente los síntomas depresivos, probablemente porque sus demandas físicas y emocionales suelen superar sus beneficios. Esto resalta la necesidad de transformar los viajes en intervenciones terapéuticas estructuradas para maximizar su potencial. En contraste, las actividades recreativas muestran un efecto terapéutico más fuerte, con una participación temprana que reduce los síntomas depresivos y niveles más bajos de depresión que fomentan la participación continua en recreación a lo largo del tiempo.

Al destacar la interacción entre las teorías de causalidad social y retirada social, esta investigación propone transformar las experiencias de viaje en intervenciones terapéuticas estructuradas, abriendo una nueva perspectiva para integrar estudios de salud y turismo. El estudio fomenta que los investigadores adopten un enfoque holístico para comprender los beneficios de salud de los viajes, considerando tanto la influencia de factores externos en la salud como cómo las personas responden a su estado psicológico.
