This paper aims to discuss the importance of having several entry points into the field, via gatekeepers who do not belong to law enforcement agencies, in contexts where the police cannot be defined as trustworthy.

The argumentation of this paper is based on qualitative research on women and gangs in Honduras. An ethnographical methodology was implemented, which included over a year of observations, 65 interviews and two focus groups in gang-controlled communities and detention centers in Central America (with a focus on Honduras), between 2017 and 2020. The paper implements a feminist reflexive approach, focusing on patriarchy, positionality and silence.

Collaborating with the police as gatekeepers in gang research needs to be reevaluated. In countries such as Honduras, the police are riddled with corruption and impunity, which eventually leads to mistrust among gang members and other citizens. Hence, it is recommended to approach other, non-law enforcement, gatekeepers, who often stand much closer to the gangs and have a less conflicted or biased position toward them and toward other people living in gang areas.

A feminist reflexive approach is recommended for researching women and gangs, and thus also for choosing the right gatekeepers in the field, taking into account researchers’ and gatekeepers’ positionality.

Police corruption in relation to gangs and gang-related crimes often goes unreported and silences people living in gang-controlled areas. This paper exposes these conflicted roles, not only regarding police abuse vis-à-vis gangs and people living in gang areas but also in relation to gang researchers in the field.

Based on ethnographic research in the Paris metropolitan region, I discuss how my identity as a Black American ethnographer was implicated in this urban ethnography. Specifically, I discuss the intersections of researcher identity with that of the “researched” and how I was simultaneously framed as an insider and outsider due to different facets of my own identity. I further argue that these insights were data in and of itself as they revealed how race and racism operate in a society that has long disavowed their existence.

The majority of the previous research on hot spots policing focuses on a single set of relatively small selected experimental areas. However, given limited resources, most law enforcement agencies dispatch hot spots intervention units to several areas on a rotation basis. The purpose of this paper is to examine policing activities in hot spots to determine if the various types of crimes were affected when deployment was applied on a rotation basis.

This study uses data from the Dallas Police Department. The differential influence of police activities, including stops, citations, and arrests, are observed against a number of aggregate crime measures (i.e. violent, property, nuisance offenses, and total index crimes). The impact of police activities have been observed for their immediate and lagged effects during the following week to measure residual deterrence effects.

It was found that the DPD's Disruption Unit's hot spots policing immediately affected violent crimes, nuisance offenses, and total index crimes, while there were no residual effects of hot spots policing. The Disruption Unit was engaged in policing activities that include motor vehicle and pedestrian stops, issuing citations, and making arrests. Among these activities, the number of police stops was the most significant factor for the reduction in violent crime and nuisance offenses.

The researchers use a patrol sector as a unit of analysis in order to compare the influence of various types of police activities on crime across a broader area. Future research should consider using an intermediate geographic unit of analysis (e.g. patrol beat).

The paper examines the differential influence of policing activities on different types of crime around hot spots when deployment was applied on a rotation basis. Both immediate and lagged effects were investigated to find residual deterrence effects of hot spots policing.

The purpose of this paper is to classify and identify the acoustic emission (AE) signals of 304 stainless steel during stress corrosion process.

The corrosion behavior of a specimen during slow strain rate testing (SSRT) in acidic NaCl solution was studied. The AE signals during the corrosion process were classified based on K‐means cluster algorithms; meanwhile, the characteristics of different AE sources were analyzed.

The results indicated that the AE characteristics of different AE sources, such as pitting, cracking, and bubble break‐up, differ significantly. The 304 stainless steel was prone to the occurrence of stress corrosion cracking under the SSRT condition in acidic NaCl solution.

The characteristics of different AE sources during corrosion process were gained for the first time, which could be of much help in analyzing and judging the corrosion situation.

Concerning that limited explanation exists examining the function of corporate governance in trust processing within entrepreneurial network development, the purpose of this paper is to explore trust evolution and the role of corporate governance in an entrepreneurial network.

This paper makes an innovative exploration based on the case study of NVC Lighting Holding Limited.

It proposes that in the initial period of network relationship which is based on entrepreneur’s individual social network and embodies sole social network embeddness, entrepreneurial network relies more on affective trust than contractual trust. When stepping into extending period of network relationship which reflects separate embeddedness of social and market network, however, entrepreneurial network has an equal reliance on both affective trust and contractual trust. With further development, when ushering in the phase of maturity which undergoes superimposing embeddedness of both social and market network, entrepreneur network inclines to rely more heavily on affective trust than contractual trust. During the whole process, it can be found that the reliance of entrepreneurial network on trust has the tendency to transfer from affective trust to contractual trust. Furthermore, decreasing of equity ratio of founders and strengthening of controlling right heterogeneity in the corporate governance have facilitated the transfer process and the entrepreneurs’ authority has restraining effect on the evolution of the process.

Through case study, this paper presents the trust evolution process in different stages of entrepreneurial network. Another important theoretic contribution of this paper is that it reveals the function of corporate governance in trust processing within entrepreneurial network development.

The purpose of this paper is to examine the threshold effect of group size on customer's complaining intention under group service failures.

Based on two main laboratory experiments, through two 10×2 scenario simulation experiments, the authors examine the role of group size in customer's complaining intention.

Results show that: (1) the relationship between group size and customer's complaining intention follows an inverted “U” type trend; (2) evaluation apprehension mediates the relationship between group size and customer's complaining intention; (3) relational distance can change threshold values and (4) relational distance moderates the relationship between group size and customer's complaining intention.

Managers should judge the threshold of group size through experience so as to have a preliminary understanding of customer evaluation concerns and complaint intention. In the face of service failure groups smaller than the threshold range, managers should divided the group into several small groups. For service failure groups larger than the threshold range, the opinion leaders in the group should be given more attention, so as to control the whole group.

This paper is helpful to deeply understand the key role of group size in the process of customer complaints, and also provides decision-making basis for service enterprises to deal with group customer complaints.

There has been little research about the threshold effect of group size on customer's complaining intention. The previous studies on customer's complaining intention focus on its influences on group size, and draw a single common conclusion that the customer's intention to complain will increase with the growing number of groups increases. However, few studies are explored on the threshold of group size. Therefore, this paper will focus on the threshold effect of group size on customer's complaining intention to fill the gap.

The purpose of this paper is to report an investigation of the acoustic emission (AE) characteristics of the corrosion process of 304 stainless steel in acidic NaCl solution.

The corrosion behavior of a specimen with constant load in acidic NaCl solution was studied, and the AE signal characteristics of the corrosion process were analyzed. Stress corrosion cracking of the specimen was detected using the AE and electrochemical noise (EN) techniques, and the acquired data were compared.

The results indicated that AE technology is very sensitive to the AE signals generated by 304 nitrogen controlled stainless steel in acidic NaCl solution. The characteristics of AE signals at different stages of the corrosion process are significantly different. Additionally, the AE test result is confirmed by the EN test results.

The characteristics of AE signals at different stages of the corrosion process are gained for the first time, which is an important guide by which to distinguishing different stages of corrosion.

The purpose of this paper is to report an investigation into acoustic emission (AE) characteristics of the corrosion situation of the bottom of a large storage tank.

Guard sensors were applied in on‐line AE inspection of a tank bottom, and the AE signal characteristics of the corrosion areas of tank bottom were analyzed. The AE test results were compared with those from an internal tank internal test.

It was observed that guard sensors could shield effectively a large proportion of the extraneous noise signals inside the tank. The characteristics of AE signals from different types of corrosion were significantly different. A comparison of AE test results and tank internal inspection data showed a good agreement.

Characteristic AE signals from different types of corrosion were obtained for the first time, which assisted in the identification of the tank bottom corrosion situation.

This research aimed to assess the leadership role of principals in the implementation of peace education in selected secondary schools in the Western Cape, South Africa.

This study employed qualitative research approach to assess the leadership role of principals in the implementation of peace education in selected secondary schools in the Western Cape, South Africa. Data were gathered from a small sample of six principals from six selected secondary schools which were engaged in the implementation of a peace education programme, and data were analysed using thematic content analyses.

Findings of the study suggest that principals possess a low level of understanding or awareness of their leadership role in the implementation of peace education. The study pointed out the constraints such as time constraints and learners' negative attitudes and social influences hinder the effective implementation of peace education in selected secondary schools.

First, the data were self-reported and therefore subject to social desirability bias; participants may have provided socially desirable responses rather than their true belief or experiences. Thus, participants may have overstated their role in and commitment to the peace education programme.

Studies that aim to explore alternative approaches to combat violence, such as peace education, are still limited in South Africa. Hence, this paper served to close that gap by contributing to the growing body of research on the leadership role of the principal in the implementation of peace education in the school and exploring barriers hampering its effective implementation.

The purpose of this paper is to give a critical review of the City-State Theory by Wan Chin of Hong Kong. Chin is referred to as the “Father of Hong Kong Independence,” and his two books about the City-State Theory of Hong Kong are popular among the netizens in Hong Kong as a new model of Hong Kong-China (People’s Republic of China (PRC)), in which Hong Kong is considered a city-state and should be fully segregated from the PRC other than in seeking its help in military and diplomatic functions. This paper will aim to review his works with the view of nationalism and nativism theories.

This paper uses nationalism theories with particular focus on Benedict Anderson’s Imagined Communities and theories on American nativism. Then an effort is made to compare these theories against Chin’s arguments on his City-State Theory. This paper also compares his theories against China’s state-nationalism raised by Professors He and Guo.

This paper concludes that Chin advocates a “Hong Kong Nationalism,” a blend of traditional Chinese culture and moral values (he used the term Huaxia), but with a Western influence, into a typical Hong Kong culture. His theory fits into Anderson’s arguments of allowing Hong Kong citizens to imagine Hong Kong as a nation, through the “ramparts” of the city-state. His nativist advocacies also have shown strong nationalistic sentiments. He argues that China should be built in the Hong Kong model before the PRC intervention.

Despite his fame, this paper is the first comprehensive academic paper to review Chin’s theories. This paper introduced the notion of “ramparts” and how this has become the backbone of Chin’s nationalism advocacies.
