Abstract

Purpose

Based on DNase I and reduced graphene oxide (rGO)-magnetic silicon microspheres (MNPS), a highly sensitive and selective fluorescent probe for the detection of PD-L1 was developed.

Design/methodology/approach

Here °C we present a feasibility of biosensor to detection of PD-L1 in lung tumors plasma. In the absence of PD-L1°C the PD-L1 aptamer is absorbed on the surface of graphene oxide modified magnetic nanoparticles °8rGO-MNPS°9 and leading to effective fluorescence quenching. Upon adding PD-L1°C the aptamer sequences could be specifically recognized by PD-L1 and the aptamer/PD-L1 complex is formed°C resulting in the recovery of quenched fluorescence.

Findings

This sensor can detect PD-L1 with a linear range from 100 pg mL−1 to 100 ng mL−1, and a detection limit of 10 pg•m−1 was achieved.

Originality/value

This method provides an easy and sensitive method for the detection of PD-L1 and will be beneficial to the early diagnosis and prognosis of tumors.

Abstract

Purpose

Milk is one of the most produced, consumed and protected agricultural commodities worldwide. The purpose of this paper is to assess how trade-opening policies can foster food security in the Chinese milk sector.

Design/methodology/approach

The empirical evidence proposed in our paper is based on time series data from the National Bureau of Statistics of China (2019) and FAOSTAT (2020). Differences in income elasticity between urban and rural areas are estimated by OLS regressions. The data also provide empirical evidence to assess to what extent and to which countries China is resorting to meet its growing demand.

Findings

Per-capita milk consumption of Chinese is rising. The authors’ estimates show that milk income elasticity is higher in rural areas. China is also progressively increasing its dependence on imports. Producers who benefit the most are those from countries implementing trade-opening policies.

Research limitations/implications

Other methods could be applied, by way of example, the gravitational model.

Practical implications

Trade agreements and the removal of barriers could be effective responses to protectionist pressures and to food security concerns.

Social implications

The case examined is of particular interest as it intervenes on food security and safety.

Originality/value

The paper adds value and evidence to the effects of trade on food security in a country with limited and exploited natural resources addressing a health emergency and environmental concerns.

Abstract

Purpose

In this study, suggestions on the protection and development of marine resources, sea area use and management, improvement of laws and regulations, monitoring of marine resources and impact assessment of marine environment are put forward.

Design/methodology/approach

Literature research method.

Findings

A major factor contributing to the decline in fishery resources is excessive fishing. At present, there are many problems to be solved in the exploitation and utilization of marine mineral resources in China. The pollution problem of marine tourism resources is becoming increasingly serious. Overmining of coastal sea resources has led to planning and management failures.

Originality/value

This paper discusses the current situation of marine resource exploitation and protection in China and analyzes the reasons for excessive resource exploitation from three aspects of marine concept, laws and regulations and marine management.

Abstract

Purpose

Food security is an essential measure of welfare, especially for low-income families in developing countries. Policy makers should be aware of the harm food insecurity has on vulnerable households. This chapter empirically addresses the problems of measuring and monitoring food security in Mexico.

Methodology/approach

We identify the macro and micro approaches for measuring food security. The macro approach uses variables at the country level. Usually, this information is available on a yearly basis, is easy to implement, and can be compared across countries. The micro approach uses household questionnaires to collect food security information. Our analysis suggests that a macro approach will not be as precise as the micro approach due to inequality (agroclimatic, social, and economic).

Findings

Empirical experience suggests that food insecurity and its severity can be captured at the household level using the Food Insecurity Experiences Questionnaire. This questionnaire allows us to calculate food security measurements that closely follow the food security definition.

Originality/value

From a public policy perspective, the different methodologies for measurement do not consider all the dimensions of food security as defined by the term. This chapter examines which approach provides the best measurement of food security.

Abstract

Purpose

This paper aims to present the case of Jón Gnarr's leadership as he served as a mayor of Reykjavík, the capital of Iceland. The authors’ view is that his leadership style illustrates a case study of how a “new” leadership style can emerge in times of crisis. Iceland was significantly affected by the financial crisis in 2008, which led to political and economic crises, which were fuelled by the public's anger and lack of trust. In 2010, Jón Gnarr and his new party, the Best Party, were unexpectedly elected. Before he became known as an unorthodox leader, he worked as a comedian. However, he influenced the discourse in politics in the country and raised trust in the system again while empowering the public managers and simplifying the system while downsizing it. This paper explores and sheds light on the leadership abilities that crises can birth.

Design/methodology/approach

This research uses qualitative methods. Seven in-depth interviews were conducted, and the interviewees included Jón Gnarr, three key political leaders who were in office at that time and three executive-level leaders from the city administration.

Findings

Evidence suggests that Jón Gnarr and his political party became a part of the political arena due to extreme social and economic factors, which might indicate the factors that can give rise to an unorthodox leader. At the same time, the research portrays the image of a leader that closely matches the theories of authentic leadership, and his leadership style at the time made a lasting impact. When Gnarr stepped into the role of mayor of Reykjavík, he used novel tactics. His political discourse was different; his manner with the public as well as within the system was different. When he became mayor, he demonstrated trust, respect and care as his underlying values. His unorthodox political behaviour appears to have empowered public officials. Thus, gradually, he inspired his followers to change their own communication style. He also addressed traditional political issues such as downsizing, mergers and financial undertakings.

Research limitations/implications

Its limitation is that it is difficult to generalize based on one case.

Practical implications

The case can shed a light on how unorthodox leadership style can unlock the potential of empowering and trust in a traditional political system. Leaders who dare to be different can raise awareness of those who work within the system as well as the public.

Originality/value

This paper contributes to the understanding of authentic and unconventional leadership as an efficient vehicle in unusual circumstances in a public leadership position.

Abstract

Purpose

This research aims to better understand the factors and determinants that shape the job satisfaction of European family business owners.

Design/methodology/approach

The study is based on a unique sample of 11,362 European family business owners surveyed within the European Union Labour Force Survey (EU LFS) framework, and the main findings were obtained by estimating ordered logistic regression models.

Findings

The authors show that only 26.8% of European family business owners are women, which underlines the gender imbalance in family business ownership, and the authors' results also report that their job satisfaction is significantly lower compared to males. The authors also find the highest job satisfaction amongst family business owners with master-level degrees and point out several interesting statistically significant differences across the industry focus of the family business.

Originality/value

This research contributes to the body of knowledge on the job satisfaction of family business owners by conducting a large-scale study based on a statistically representative sample of European respondents.

Abstract

The cities, for the most part, appeared up until the middle of the 1990s to be islands within the larger Chinese political economy in which job-secure workers could be certain that their livelihood, health, education, and living abodes would evermore undergird their and their children's sustenance. At least until the late 1980s, urbanites who stuck with the state sector even considered good treatment on the job a kind of birthright, an entitlement that was sure to be enforced. In the cities, true, there had always been the disadvantaged after 1949 – those without offspring or spouses, the disabled, and people unable to support themselves. But this relatively tiny batch of individuals generally survived in the shadows and out of sight, subsisting – but just barely – as members of the “three withouts” on a mere pittance, in the form of meager “social relief” disbursed by civil affairs departments.8

Abstract

Among U.S. children, research indicates that early childhood experiences, including the child care environment, affect later educational outcomes. Yet, research on educational stratification in low-income countries rarely features the preschool years. We investigate the organization of child care among preschoolers in China. In-depth interviews reveal that grandmother care and formal care are highly desirable. Formal care, in particular, is perceived to provide educational advantage. Using China Health and Nutrition Survey (CHNS) data, and mixed random effects logit models, we explore the determinants of grandmother care and formal care. Results suggest poverty is associated with gender bias; in low-income households, boys without siblings are especially likely to receive formal care. These results call for greater attention to early childhood in research on educational stratification in China and other low-income settings.

Abstract

Purpose

The current review aims to examine the growth trajectory, most influential documents, intellectual and conceptual structure of the literature regarding gender issues in family business research.

Design/methodology/approach

The bibliometric analysis was performed using 224 documents from 1991 to 2020 extracted from the Web of Science database.

Findings

The review finds that this field's knowledge grew exponentially during the last three decades, mainly after 2003 and the last several years. Based on the co-citation analysis, three major research lines are identified: “Women's challenges and opportunities in the family business”, “Gender diversity in the family business corporate board”, and “Gender and family SMEs management.” The temporal co-word analysis reveals that “Gender diversity in the family business corporate board” is the latest research line.

Originality/value

By reviewing prominent cited references and documents that cited them, the authors provide the landscapes and research gaps of three major research lines for further development.
