Black Land

PurposeThe authors are committed to providing the Chinese government with a foundation for making decisions that will protect black land and ensure long-term agricultural development.Design/methodology/approachUsing the grounded theory approach, this study investigates the influencing factors affecting the quality of black land in Northeast China and proposes a hypothetical model for the mechanism of the influencing factors on the quality of black land in Northeast China.FindingsThe factors influencing the quality of black land include not only soil quality, ecological quality and environmental quality, but also economic quality and management quality, and can be classified into five categories. There are complex influence relationships between various factors and black land quality, with soil quality, ecological quality, environmental quality and management quality having a positive influence on economic quality. Soil quality, ecological quality and environmental quality are all improved as a result of good management. Black land quality is influenced positively by environmental quality, economic quality and management quality.Research limitations/implicationsThe quality of black land is a major concern in terms of food production and long-term agricultural development. The black land in Northeast China was chosen as the subject of this study, and the research findings have some limitations. The next step will be to expand from studying the black land in Northeast China to the black land worldwide.Originality/valueIn Northeast China, the quality of the five dimensions of black land must be improved in a coordinated and consistent manner.

Cointegration Relationship

The relationship between foreign direct investment, which is a type of cross-border and long-term investment, and environmental quality is a current issue that is heavily debated. Foreign direct invesments can ensure economic growth and development of countries, while also causing a change in environmental quality. In the research conducted, it is seen that changes in carbon dioxide emissions with foreign direct capital inflows are mainly investigated from the point of view of the host countries. However, foreign direct invesment outflows may have an impact on the environmental quality of the home country. Because foreign direct invesment outflows can enable the transfer of more environmentally friendly techonogies to the country and strengthen management skills. The impact of foreign direct investment outflows on the home country's environmental pollution is shaped by many factors (scale, technique, and composition effects). In addition to these effects, it is necessary to pay attention to the regional and sectoral distribution of capital outflows. The main aim of this study is to examine the links between Turkey's foreign direct invesment outflows and carbon dioxide emissions for the period 1990-2018. For this reason, a unit root test was applied to variables whose natural logarithm was taken. Tests showed that all series are stable of the same degree. Engle&Granger(1987) and Granger&Yoon(2002) tests were used to determine the cointegration relationship between variables. The crouching error correction model(CECM) was applied to determine the causality relationship. According to the results of the analysis; i) In terms of the Engle&Granger(1987) test, there was no long-term relationship between variables. ii) According to the Granger&Yoon(2002) test, it was determined that there is a bidirectional hidden cointegration relationship between the positive shocks of carbon dioxide emissions and negative shocks of foreign direct invesment outflows. iii) There is a bidirectional asymmetric causality relationship between the positive shocks of carbon dioxide emissions and the negative shocks of foreign direct invesment outflows. iv) It is observed that 1% negative shocks in foreign direct invesment outflows reduce positive shocks in carbon dioxide emissions by 0,26%. As a result, since negative situations in foreign direct invesment outflows have an effect on improving the quality of the environment, the environmental dimension should be taken into account in the policies to be made.

PurposeChildren suffering from cancer or cardiovascular disease, who need extended periods of treatment in hospitals, are subjected to multiple hardships apart from the physical implications, for example, experienced isolation and disrupted social and academic development. This has negative effects long after the child's recovery from the illness. The purpose of this paper is to examine the non-medical needs of children suffering from a long-term illness, as well as research the field of artificial intelligence (AI) – more specifically, the use of socially intelligent agents (SIAs) – in order to study how technology can enhance children's interaction, participation and quality of life.Design/methodology/approachInterviews were performed with experts in three fields: housing manager for hospitalized children, a professor in computing science and researcher in AI, and an engineer and developer at a tech company.FindingsIt is important for children to be able to take control of the narrative by using an SIA to support the documentation of their period of illness, for example. This could serve as a way of processing emotions, documenting educational development or keeping a reference for later in life. The findings also show that the societal benefits of AI include automating mundane tasks and recognizing patterns.Originality/valueThe originality of this study concerns the holistic approach of increasing the knowledge and understanding of these children's specific needs and challenges, particularly regarding their participation and interaction with teachers and friends at school, using an SIA.

In this study, we consider the issue of sustainable development in the supply chain consisting of an original equipment manufacturer (OEM) and a contract manufacturer (CM). We investigate how to facilitate the CM’s investment in the environmental quality of a product so as to properly respond to climate change. We introduce a quantity incentive contract, and obtain the optimal solution based on a Stackelberg game. The OEM, as the focal company, determines the level of the incentive, and the CM, responsible for product design and production, determines its level of environmental quality given the OEM’s incentive offer. To investigate the effectiveness of the quantity incentive contract and provide important implications, we analytically compare the quantity incentive contract with the basic wholesale price contract without any incentives and conduct numerical experiments. Our results reveal that the quantity incentive contract facilitates the CM’s investment in environmental quality, and enhances the environmental, market, and profit performance of not only the CM but also the OEM which pays the incentive. We also show that the quantity incentive contract is suitable to develop a long-term relationship between the OEM and the CM.

The Impact

Purpose The purpose of this paper is to look at peer support in the context of broader communities. Design/methodology/approach It builds on the author’s experience working with the Mental Health Foundation of developing delivering and evaluating several self-management and peer support initiatives in a variety of settings with a range of different peer groups. It will consider what constitutes a peer and a community, and explore the notion of community solutions for community problems. Findings Peer support in community settings has the capacity to address social isolation, build skills and self-esteem and give individuals a better quality of life – it can also add value to whole communities and reframe the way entire groups are considered within them. It has the ability to be both more accessible and less stigmatising and thus reach more people. This also offers community based peer support as a contributor to preventing the deterioration of mental health and potentially reducing the impact of mental ill-health. Social implications The author needs to think more in terms of whole community and get better at improving how the author measures and articulates this community benefit. This will allow us to make better decisions about how best to apply resources for long term whole community gain. Peer support and peer leadership needs to be at the heart of this process. Originality/value This paper places a familiar approach in a different setting placing peer support firmly outside services and within comunities.

Tourism Potential

Significance The news follows years of healthy growth in the sector and comes as the government launches a new tourism plan. President Andres Manuel Lopez Obrador (AMLO) announced the National Tourism Strategy 2019-24 in Chetumal on February 24, highlighting the government’s intention to use the sector as a vehicle for regional development, job creation, social inclusion and equality. Within this framework, the construction of a ‘Maya Train’ in the relatively poor south of the country will be the sector’s priority. Impacts The lack of a formal environmental impact assessment for the Maya Train puts the environment, and its long-term tourism potential, at risk. Business’s mistrust of AMLO, and the potential downgrading of Mexico’s sovereign ratings, threaten infrastructure investment hopes. SECTUR’s move to Quintana Roo feeds into the government’s decentralisation rhetoric but will not necessarily help boost sectoral growth. Plans to incentivise domestic travel by the poor may increase tourism numbers and quality of life but will bring few economic benefits.

Object.Management options for vestibular schwannomas (VSs) have greatly expanded since the introduction of stereotactic radiosurgery. Optimal outcomes reflect long-term tumor control, preservation of cranial nerve function, and retention of quality of life. The authors review their 15-year experience.Methods.Between 1987 and 2002, some 829 patients with VSs underwent gamma knife surgery (GKS). Dose selection, imaging, and dose planning techniques evolved between 1987 and 1992 but thereafter remained stable for 10 years. The average tumor volume was 2.5 cm3. The median margin dose to the tumor was 13 Gy (range 10–20 Gy).No patient sustained significant perioperative morbidity. The average duration of hospital stay was less than 1 day. Unchanged hearing preservation was possible in 50 to 77% of patients (up to 90% in those with intracanalicular tumors). Facial neuropathy risks were reduced to less than 1%. Trigeminal symptoms were detected in less than 3% of patients whose tumors reached the level of the trigeminal nerve. Tumor control rates at 10 years were 97% (no additional treatment needed).Conclusions.Superior imaging, multiple isocenter volumetric conformal dose planning, and optimal precision and dose delivery contributed to the long-term success of GKS, including in those patients in whom initial microsurgery had failed. Gamma knife surgery provides a low risk, minimally invasive treatment option for patients with newly diagnosed or residual VS. Cranial nerve preservation and quality of life maintenance are possible in long-term follow up.

Relational Change

PurposePrior research has suggested that the key to industrial purchasing success lies in the time development and maintenance of long‐term relationships between buyers and sellers. Good relational exchanges can lead to higher product quality and better coordination with the suppliers. As such, the purpose of this article is to explain how the change of these relationships over time is critical to successful purchasing, especially in understanding the factors that influence the relational change.Design/methodology/approachThree mini case studies are presented as an attempt to capture the subtle development of buyer‐seller relationships in the Asian printed circuit board industry. The approach used in this paper is to treat the relationship development as a process through time using Ford's model from 1980. Ford's model is appropriate as it allows the examination of time effects in relationships, factors influencing the change and the implications of having close linkages.FindingsInitial results suggest that technological, social, time and actual distances, other than the quality of the relationships, can impact relationship development.Originality/valueThe results of this study suggest that buyers should consider carefully the influence of the geographical proximity of suppliers. As such, buyers could seek the services of personnel or departments who are more attuned to the supplier's local culture.
