The purpose of this paper is to determine whether the diagnosis of both carers’ mental health problems and substance misuse increase the likelihood of recurrent child maltreatment over and above the individual effects of these factors.

Retrospective secondary data analysis of 29,455 children where child maltreatment was confirmed in the Victorian child protection system between 2001 and 2005. Recorded mental health, alcohol misuse and other drug misuse variables were entered into multivariate logistic regression models predicting repeated child maltreatment. Interactions and a range of other child, carer and socio-economic factors were included in these models.

Carer alcohol misuse, other drug misuse and mental ill health all independently predicted recurrent child maltreatment. The presence of both other drug misuse and mental ill health increased the likelihood that recurrent child abuse was recorded over the likelihood that mental health alone predicted recurrent child maltreatment, and while alcohol misuse had an effect when there was no mental health condition recorded it did not have an additional effect when there was evidence of mental health problems.

Children in families where there is both mental health problems and other drug use problems are at greater risk of repeated maltreatment than where there is evidence of mental health problems or other drug use alone. Where there was evidence of carer mental health problems, alcohol misuse did not add to this likelihood. However, the effect of mental health and other drug use was similar in size to the effect of alcohol misuse alone.

These findings add to understandings of the effects of co-occurring mental health problems and substance misuse on recurrent child maltreatment and differentiate between cases that involve alcohol and other drug misuse.

Nobody concerned with political economy can neglect the history of economic doctrines. Structural changes in the economy and society influence economic thinking and, conversely, innovative thought structures and attitudes have almost always forced economic institutions and modes of behaviour to adjust. We learn from the history of economic doctrines how a particular theory emerged and whether, and in which environment, it could take root. We can see how a school evolves out of a common methodological perception and similar techniques of analysis, and how it has to establish itself. The interaction between unresolved problems on the one hand, and the search for better solutions or explanations on the other, leads to a change in paradigma and to the formation of new lines of reasoning. As long as the real world is subject to progress and change scientific search for explanation must out of necessity continue.

The recent pandemic of Covid-19 has substantially changed people’s daily lives. They work and interact even more based on information and communication technologies (ICT). The use of new technologies and the interconnectivity specific to smart cities have intensified in the context of the pandemic. A significant part of the population works from home, participates in concerts and other remote social activities, organizes online parties, communicates virtually with friends and family, etc. These transformations required an extended and more stable infrastructure, significant investments in the development of software applications dedicated to remote activities (streaming, contact tracing, security, online ordering and delivery, telemedicine, etc.), in specific services (data storage and applications, electronic signature services, etc.) and the integration of subsystems used in smart cities. This chapter examines the role of SARS-CoV-2 pandemic in the acceleration of digital transformations in smart cities due to the need and desire to digitize communities and public administrations. It has become a top priority for both private and public companies from smart cities in the context created by the pandemic.

This essay seeks to extend the original gambit of this forum, of thinking possible modes of postcolonial sociology, unto a more relational terrain. It takes as its point of departure the vexed status of history in sociology and the hermeneutic suspicion of comparison in postcolonial theory. Any potential rapprochement between postcolonial theory and sociology must engage with the deeply incongruent status of history and comparison across these fields. I attempt to bridge this divide historically by revisiting an anti-imperial internationalist sociology forged in interwar colonial India. I seek thereby to show what Pierre Bourdieu called a “particular case of the possible” and to participate in ongoing efforts to “provincialize” sociology.

The purpose of this paper is to investigate market power in the Chinese pork supply chain. The authors aim to explain why a steady rise in prices is observed in the sector, apart from existing evidence on incomplete/asymmetric cost pass-through and concerns of growing concentration and consolidation in the sector.

This study uses a new empirical industrial organization model for both oligopoly and oligopsony power to measure the degree of market power exerted on consumers and hog farmers simultaneously.

By examining annual panel data across provinces in China, the authors find that both oligopoly and oligopsony powers exist in the pork supply chain. In particular, the authors determine that a higher degree of market power is found to influence prices paid to hog farmers than prices paid by pork consumers. Estimates of key elasticities in the Chinese pork supply chain are also updated based on the structural model estimation and the latest data.

Due to the lack of data at a more granular level of geography, the authors are only able to estimate market power by three major economic regions.

The findings provide useful information for future policy analyses of Chinese food markets. First, the pork-packing industry should be of great concern in terms of market power and its influence on consumers’ and farmers’ welfare. It is essential to take into consideration market power in the pork supply chain before making any public policy regarding the pork market. Furthermore, following economic theory and experience from developed countries, large meat packers will eventually vertically control hog farmers given their stronger oligopsony power over the upstream. Vertical integration may be the next important issue in terms of food market competition. Finally, the results may also draw the government’s attention to investigating market competition in all major food markets.

The empirical evidence draws attention to the issue of food market competition in one of the largest and most important meat-packing markets in China. The authors hope to encourage further discussions on pork and hog market regulations and related public policies.
