Based on the analysis of the current new rural construction in China and relationship of origin and resource of city and countryside, the tridimensional development of rural residences are proposed to improve the land use efficiency in response to the demand for garden leisure and tourism from city levels in the urbanization process from the prospect of urban and rural complementation and resource optimization. It will thereby convert the industrial structure in the countryside, develop the local eco tourism and relevant service industries and increase the income and employment opportunities of farmers, which can change the quality of rural life and establish the tridimensional development models of new rural residence in China under the mechanism of city and countryside complementation and interaction fundamentally.

Town land is the carrier of town’s economy, society and environment, and its land use efficiency has a close relationship with town’s economic development as well as living environment construction. This study selects towns of Zigui County as research objects to explore characteristics of land use efficiency in mountain areas. The study results show that: 1) Maoping, Lianghekou, Meijiahe and Moping, of which technical efficiency and scale efficiency equal to 1, achieve the best condition of land use efficiency. 2) In Quyuan, Guizhou, Shuitianba, Xietan and Zhouping, moderately enlarging towns’ scale will be helpful to strengthen agglomeration economy effect, and improve towns land use efficiency. While in Shazhengxi, Yanglinqiao and Guojiaba, it needs to decrease these towns’ scale moderately to prevent the waste of resource. 3) Inputs’ inefficiency and outputs’ insufficiency are the main factors result in the differences of input and output efficiency. 4) Accelerate Industrial Restructuring, optimize Industrial Structure, improve service efficiency of fixed assets investments, appropriately control the scale of construction land are the most important way to improve land use efficiency in Zigui County.

Currently, the practice of Crop-Livestock Integration is stimulated as a way of increasing the generation of foreign exchange for Brazil. Integrated systems improve land use efficiency as well as preserve, recover and increment or soil fertility. The aim of this research was to evaluate how different doses of nitrogen fertilization can affect production and quality of dual purpose wheat submitted to grazing. The experimental designed was randomized block with five treatments (0, 75, 150, 225 and 300 Kg N ha-1, like ammonium nitrate) and four repetitions. The forage yield, the percentage crude protein (P=.0001) and acid detergent insoluble protein (P=.0054) had a linear increased because of the nitrogen addition doses. The crude protein percentage changed the estimate of all soluble carbohydrates (P=.0001) and non-fibrous carbohydrates (P=.0186), but did not influence the, nitrogen detergent fiber corrected with ash and proteins percentage contributing for content cell. The crops production (P=.0001) and the number of kernels per ear (P=.0001) showed significantly difference because of the nitrogen additions dose, increasing the number of fertile flowers. The nitrogen topdressing alters forage production, the chemical composition and the production of dual purpose wheat grains subjected to grazing.

On The Road

In the recent 10 years, China’s housing prices and land prices have risen rapidly, resulting in precious land resources, thus restricting the development of the cities. How to effectively measure urban land-use efficiency and how to optimize it has become a stumbling block on the road of sustainable development in China. This article focuses on the vital province in southwest China—Sichuan Province, which is facing the problem of insufficient land-use efficiency and uses the data of 32 cities from 2003 to 2018 to carry out the research. Based on the measurement results of urban land-use efficiency in Sichuan Province and its temporal and spatial evolution characteristics, this paper uses the SDM model to verify that the land-use efficiency can be optimized from the three aspects of innovation, industrial structure, and economic connections. The conclusion shows: (1) There is a weak decoupling relationship between urban land use and economic development in Sichuan Province. The urban land-use efficiency has the characteristics of polarization of more than two ends and less in the middle, but the gap is gradually reduced; (2) Time series level, urban land-use efficiency in various regions is increasing, and potential benchmark technology progress is the main reason for the increase; (3) At the spatial distribution level, urban land-use efficiency has spatial autocorrelation, forming an obvious “center-periphery” distribution pattern; (4) Innovation, economic connection, and industrial structure optimization can promote the improvement of land-use efficiency, and economic connection has a positive spillover effect on the land-use efficiency of surrounding areas. Accordingly, this study puts forward some targeted suggestions on improving urban land-use efficiency in Sichuan Province.

Assessing the performance of legume species as companion plants is a prerequisite for promoting a low chemical-input durum wheat production system. This study aims to evaluate fenugreek (IC-Fen), clover (IC-Clo) and their mixture (IC-Mix) performances on weed control, productivity, and grain quality of durum wheat main crop under different N fertilization regimes, as compared to durum wheat alone with (SC-H) and without (SC-NH) herbicide. On-field experimentations were carried out in humid and semi-arid conditions. Results showed that legumes offer significant advantages in terms of weed control, soil moisture conservation, productivity, and grain quality for durum wheat cash crops. Results explain that these benefits depend on the legume part and the adopted N fertilization regime. Most significant improvements occurred with the IC-Mix under unfertilized conditions (N0) and relatively low and late N regimes (N1 and N2) where, for example, the partial land equivalent ratio of durum wheat grain yield (PLER) reached 1.25 compared to the SC-NH, with no need to sort the raw grain product (legumes seeds not exceeding 4.3%). Our study illustrates that under low and late N-fertilization condition using promising legumes species combinations result in the improvement of N fertilizer land-use efficiency and hence help to reduce N-fertilization inputs.

And Performance

To what extent does the evolution of 20th-century residential area planning and development reflect the profound changes that have affected society over this period? How much was this evolution shaped by successive planning models formulated over the last century? The paper reports on an analysis of the land-use patterns of four neighbourhoods developed at different times over the 20th century. Data originate from field surveys and a systematic measurement of the land uses of the study areas. Findings paint a mixed picture. They show that some societal changes (rising affluence for example) have affected neighbourhood morphology, whereas others (such as cultural diversification) have left few traces. A comparison of different land-use features identifies both the advantages and downsides of each neighbourhood's morphology. It becomes difficult in this light to perceive the evolution of neighbourhood planning as a linear progression towards improved land-use efficiency and quality of life.

Purpose The purpose of this study was to identify levels of self-compassion in adults who do and do not stutter and to determine whether self-compassion predicts the impact of stuttering on quality of life in adults who stutter. Method Participants included 140 adults who do and do not stutter matched for age and gender. All participants completed the Self-Compassion Scale. Adults who stutter also completed the Overall Assessment of the Speaker's Experience of Stuttering. Data were analyzed for self-compassion differences between and within adults who do and do not stutter and to predict self-compassion on quality of life in adults who stutter. Results Adults who do and do not stutter exhibited no significant differences in total self-compassion, regardless of participant gender. A simple linear regression of the total self-compassion score and total Overall Assessment of the Speaker's Experience of Stuttering score showed a significant, negative linear relationship of self-compassion predicting the impact of stuttering on quality of life. Conclusions Data suggest that higher levels of self-kindness, mindfulness, and social connectedness (i.e., self-compassion) are related to reduced negative reactions to stuttering, an increased participation in daily communication situations, and an improved overall quality of life. Future research should replicate current findings and identify moderators of the self-compassion–quality of life relationship.
