Information technology systems implementation and processes of integration and disintegration: case study evidence from Air Greenland
Authors: Balslev Lars , Thrane Sof , Friis Ivar 
Published: July 2021

Purpose
This paper aims to analyze the impact of information technology (IT) system implementation on the integration of data and information between sales and accounting departments, and how data integration affects relations with supplier and customers.

Design/methodology/approach
The change between three different reservation and distribution systems in an airline company was assessed over 20 years based on qualitative data collected while events unfolded and interviews that traced events retrospectively.

Findings
This study finds that data integration challenges affect the capacity to use revenue and sales data for control purposes and integrating with suppliers and customers. The systems either facilitated the ability to integrate sales and accounting data or enabled integration in wider supplier and customer networks. The implementation of different reservation and distribution systems resulted in a trade-off between integration within the firm and into wider customer and supplier networks.

Research limitations/implications
Data were mainly obtained from the focal firm, Air Greenland. The protracted study period meant that the data were not as concentrated as they would have been had the analysis been performed over a shorter duration or had the focus been on one implementation process.

Originality/value
Extant research suggests that integration challenges when implementing IT systems are caused by differences in information needs between groups with different logics. The authors illustrate how data integration is also a crucial challenge when implementing IT systems.
Profits to opportunistic insider trading before and after the Dodd-Frank act of 2010
Authors: Gangopadhyay Partha , Yook Ken 
Published: July 2021

Purpose
The authors examine if opportunistic insider trading profits decrease after the enactment of the Dodd-Frank Act (DFA) in 2010. The DFA expands legal prohibitions on insider trading in the USA.

Design/methodology/approach
The authors identify opportunistic insider trades following a method that is outlined in Cohen et al. (2012). The authors examine univariate statistics and perform multivariate regression tests to examine opportunistic trading profits before and after the DFA. Similar multivariate regression tests have been used widely in the literature to examine the profitability of insider trades.

Findings
The authors find that opportunistic insider purchases were highly profitable before the DFA. Profits after opportunistic purchases were significantly lower after the DFA. Opportunistic insider sales were contrarian trades both before and after the DFA. However, share prices kept increasing after insiders sold their shares.

Originality/value
To the best of the authors’ knowledge, the paper is the first study that compares the profitability of opportunistic insider trades, as identified by Cohen et al., before and after the DFA. The study contributes to the literature that finds that insiders change their strategic trading behavior when the potential costs of the illegal trading increase due to regulatory action.
Current perspectives on public mental health training provision: a scoping review
Authors: Ortega Vega Marta , Attoe Chris , Iannelli Hannah , Saunders Aleks , Cross Sean 
Published: July 2021

Purpose
Public mental health training can effectively support well-being at a population level. The application of this type of training is increasingly prevalent, however, training evaluation is currently limited and inconsistent. This paper aims to summarise the characteristics of public mental health training available in England, presents key quality criteria for this training and identifies gaps in training provision.

Design/methodology/approach
This paper uses a pragmatic mixed-methods approach including database and Google Searches, focus groups and survey methods. The data analysis included a structured data extraction template for the training availability scoping and thematic analysis of the survey and focus groups.

Findings
This paper identifies a total of 74 training courses targeting workplace employees, young people and the general population. Most courses were delivered face-to-face (54), followed by e-learning (16) and blended modalities (4). This paper derives four core quality principles, focussing on the training approach, key features of training, trainer attributes and evaluation. There were no significant gaps in training provision, although areas for future development included consistency in public mental health terminology, systems and populations requiring additional training and the logistics of training delivery, etc.

Originality/value
The results contribute to the evidence base of interventions that are currently available, supporting the efforts to evaluate the impact of training provision in this area. This paper provides a novel approach to assessing training quality and discuss areas for development and innovation in this field.
Internal audit use, earnings quality and external audit fees
Authors: Prasad Nishaal , Hay David , Chen Li 
Published: July 2021

PurposeThe purpose of this study is to examine the effect of internal audit function (IAF) use on earnings quality and external audit fees using empirical data collected from the New Zealand (NZ) setting.Design/methodology/approachApplying institutional theory as the underlying framework, this study examines an IAF’s ability to demonstrate legitimacy, which will shed light to the functions long-term survival. Using a unique data set from the NZ setting, which combines information obtained from “The Institute of Internal Auditors of New Zealand” with empirical firm data collected from publicly available sources, multivariate analysis is performed to test the prediction that IAF use is associated with earnings quality, measured using discretionary accruals, and external audit fees.FindingsThere is strong positive association between IAF use and external audit fees, which supports the complementary controls view, where better internal controls increase audit fees by increasing the demand for scope of external audit work. The authors find no significant relationship between IAF use and earnings quality, which is not entirely surprising.Research limitations/implicationsThe aim is to empirically test the IAF value proposition and to delve deeper into the black box of IAF value drivers. Given the size of the NZ economy and limitations of data availability, total sample size used in this study is relatively modest. However, the analysis does yield significant results. Apart from academic contribution to knowledge, this study offers a profound list of practical contributions. Practitioners will be interested to learn about the IAF value proposition from an empirical viewpoint. Senior management (SM) will obtain value from the outcomes when contemplating IAF investment and sourcing decisions. Regulators will be inherently interested in whether IAFs should be mandated.Originality/valueThe aim is to empirically test IAF value proposition and to delve deeper into the black box of IAF value drivers.

University as a vehicle to achieve social innovation and development: repositioning the role of the university in the society
Authors: Mdleleni Lwando 
Published: July 2021

Purpose
This paper aims to explore the role of university in promoting, generating and sustaining social innovation (SI). It aimed to understand how higher education institutions have extended their contribution beyond the traditional function of teaching and research to perform in socio-economic problem-solving. It looks at the kinds of contributions which universities potentially make to SI processes, and the effects that this has on the direction and magnitude of SI, and by implication social development. This was done by drawing lessons from a SI project that the University of the Western Cape has been involved in, i.e. Zenzeleni Networks Project.

Design/methodology/approach
To address the research question with this framework, the author adopted an exploratory research design using a case study. This research is qualitative, exploratory and descriptive, based on a case study built with secondary data.

Findings
This paper submits that universities can potentially function as key role players in promoting SI initiatives and fostering social transformations. Universities contribute with different kinds of resources and inputs to foster new SI ideas.

Originality/value
The paper suggests that socially innovative university projects may contribute to community social sustainability maintaining social cohesion by increasing social capital and providing resources for the empowerment of the marginalised communities. In so doing, they contribute to overcome social exclusion and promote more sustainable forms of development at community level. More research is needed on how universities can build community networks with local community partners, who can use the insights of academic research to replicate interventions and move to scale.
Resource limitation, intra‐group aggression and brain neuropeptide expression in a social wasp
Authors: Walton Alexander , Toth Amy L. 
Published: July 2021

Abstract

Nourishment can have profound effects on social behaviour, including aggressive interactions between individuals. The prevailing theoretical and empirical understanding is that when nutritional resources are limited, inter‐individual competition and aggression will increase. Alternatively, studies from some group‐living species suggest limited nutrition can lead to increased cooperation, including by a reduction in inter‐individual aggression. Thus, a general model for understanding how and why nutritional resource limitation affects aggressive behaviour remains elusive.

We suggest that the link between nourishment and future reproductive potential may be a key missing element of models that predict how nutritional resource availability affects inter‐individual aggression in social animals.

We investigated how nourishment influenced intra‐colony aggression and its molecular correlates in colonies of the social paper wasp Polistes fuscatus, which contain workers that maintain flexible reproductive potential as adults. We subjected colonies to either a high or low feeding treatment, and examined subsequent effects on behaviour, nutritional/reproductive physiology and brain gene expression.

We found that nutritional restriction reduced aggressive interactions. Thus, resource limitation was linked to reduced intra‐group conflict. Thus, individual worker paper wasps appear to have the capacity to adjust their behaviour (e.g. reduced aggression) in response to nutritional stress; this suggests they may invest nutritional resources in the colony when resources are limiting, and in the self (and possible future reproduction) when resources are abundant.

Differential brain gene expression results implicate two well‐known neuropeptides associated with aggression and/or nutrient signalling across taxa, Tachykinin and Neuropeptide F, as possible mediators of nutritionally dependent intra‐colony aggression. This adds to a growing understanding that deeply conserved genes associated with core, conserved behaviours such as feeding and aggression in solitary insects can play a role in the regulation of social plasticity in more highly social species.

OF CROWDED HISTORIES AND URBAN THEORY: A Feminist Critique of Temporal Closure and Patrimonial Claims to the Urban
Authors: Collins Erin 
Published: July 2021

AbstractThis article contributes a feminist analysis of temporal closure to lively debates within critical urban theory. I argue that in both urban politics and urban theory, claims to a singular and totalizing historical arc flatten the heterotemporalities integral to urban life and ultimately contribute to the evacuation of a diversity of lived experience from the center of each. This argument is grounded in the empirics of contentious land politics in and around Phnom Penh, Cambodia. Through my analysis I demonstrate that the erasure of women's histories through temporal closure and the fixation on their bodies through patrimonial claim making are two sides of an urban politics that seeks to foreclose, name and claim. In this article, written in critical dialogue with planetary urban theory, I advance from this situated analysis to advocate for a crowded field of urban theory, animated by embodied analyses of time built from the heterotemporal and polyvalent lived reality of diverse urban contexts. Crowded urban theory, I argue, makes space for theory building and theory repurposing without scripting the story in advance.

Published: July 2021

ObjectiveTo assess the incidence of maternal group B Streptococcus (GBS) infection in England.DesignPopulation surveillance augmented through data linkage.SettingEngland.PopulationAll pregnant women accessing the National Health Service (NHS) in England.MethodsInvasive GBS (iGBS) infections during pregnancy or within 6 weeks of childbirth were identified by linking Public Health England (PHE) national microbiology surveillance data for 2014 to NHS hospital admission records. Capsular serotypes of GBS were determined by reference laboratory typing of clinical isolates from women aged 15–44 years. Post‐caesarean section surgical site infection (SSI) caused by GBS was identified in 21 hospitals participating in PHE SSI surveillance (2009–2015).Main outcome measuresiGBS rate per 1000 maternities; risk of GBS SSI per 1000 caesarean sections.ResultsOf 1601 patients diagnosed with iGBS infections in England in 2014, 185 (12%) were identified as maternal infections, a rate of 0.29 (95% CI 0.25–0.33) per 1000 maternities and representing 83% of all iGBS cases in women aged 18–44 years. Seven (3.8%) were associated with miscarriage. Fetal outcome identified excess rates of stillbirth (3.4 versus 0.5%) and extreme prematurity (<28 weeks of gestation, 3.7 versus 0.5%) compared with national averages (P < 0.001). Caesarean section surveillance in 27 860 women (21 hospitals) identified 47 cases of GBS SSI, with an estimated 4.24 (3.51–5.07) per 1000 caesarean sections, a median time‐to‐onset of 10 days (IQR 7–13 days) and ten infections that required readmission. Capsular serotype analysis identified a diverse array of strains with serotype III as the most common (43%).ConclusionsOur assessment of maternal GBS infection in England indicates the potential additional benefit of GBS vaccination in preventing adverse maternal and fetal outcomes.
Alternaria toxins—Still emerging?
Authors: Aichinger Georg , Del Favero Giorgia , Warth Benedikt , Marko Doris 
Published: July 2021

AbstractAlternaria molds are known to cause the contamination of food with their secondary metabolites, a chemically very heterogeneous group of compounds. Yet, after decades of research on the occurrence and the toxicity of Alternaria toxins in academia, no regulation has been implemented yet, thus leaving these potential food contaminants in the status of so‐called “emerging mycotoxins”. However, research on this topic has been far from static, leading to the European Food Safety Authority repeatedly calling for more data on the occurrence and toxicity of genotoxic metabolites such as alternariol (AOH) and its monomethyl ether (AME). To give an overview on recent developments in the field, this comprehensive review summarizes published data and addresses current challenges arising from the chemical complexity of Alternaria’s metabolome, mixture effects and the emergence of novel biological targets like cell membranes or the interaction with different receptors. Besides toxicodynamics, we review recent research on toxicokinetics, including the first in vivo studies which incorporated the rarely investigated—but highly genotoxic—perylene quinones. Furthermore, a particular focus lies on the advances of liquid chromatography/tandem mass spectrometry (LC‐MS/MS)‐based analytical tools for determining a broader spectrum of Alternaria toxins including modified/masked forms and assessing exposure via human biomonitoring (HBM).
1 Introduction: Urban Commerce in Ancient Mesoamerica
Authors: Paris Elizabeth H. 
Published: July 2021

ABSTRACTNearly three decades of research have identified evidence of commercial institutions and exchange at cities throughout Mesoamerica. This introduction examines three major areas of investigation for commercial institutions in ancient Mesoamerican cities: marketplaces and urban geography; currencies, standards and credit; and the social dimensions of urban commerce. It discusses the different ways in which the contributing authors examine different commercial economies of ancient Mesoamerica through the prism of its urban centers, and the potential of this approach for further archaeological research.
11 Implications of the Marketplace at Maax Na, Belize
Authors: King Eleanor M. 
Published: July 2021

ABSTRACTWithin the last decade a new economic paradigm has emerged that emphasizes the variability in economic strategies the pre‐Hispanic Maya employed. Among the most important developments is the discovery of marketplaces at several Classic Maya (250–900 CE) sites. Investigations into them and into market systems continue to fuel research, but invite broader consideration of what the presence of marketplaces might mean for regional systems of provision and control. The settlement densities revealed by new lidar data add urgency to this quest. Researchers should also consider the role of merchants, which is looming larger in our views of the pre‐Hispanic Maya world. This article examines the implications of the preliminary identification of a marketplace at the city of Maax Na for economic activities, actors, and market systems in the Three Rivers Region of Guatemala and Belize.

Published: July 2021

AimsThe results of associations between new oral anticoagulants (NOACs) and wound complications after total joint arthroplasty remain inconsistent. We conducted a systematic review and meta‐analysis of randomized controlled trials to make comparisons with low molecular weight heparins (LMWH) on the clinical outcomes of total wound complications, together with other efficacy and safety endpoints to further evaluate the safety and efficacy of NOACs.MethodsThis meta‐analysis was conducted based on a published protocol (PROSPERO: CRD42019140841). We searched for available articles in PubMed, Embase and Cochrane Library through Jun 62 021. Random‐effects meta‐analyses, including subgroup analyses, were conducted to estimate the pooled relative risk (RR) and 95% confidence interval (CI) for specific doses of NOACs.ResultsWe retrieved 1683 studies, of which 20 were eligible for inclusion. We found that apixaban was associated with a lower incidence of total wound complications compared with LMWH (RR = 0.81; 95% CI: 0.65–1.00), while dabigatran and rivaroxaban did not increase the risk of total wound complications. In addition, apixaban was associated with a reduction in the risk of major/clinically relevant nonmajor bleeding events compared to LMWH (RR = 0.80, 95% CI: 0.65–0.99), while rivaroxaban increased the risk for major/clinically relevant nonmajor bleeding events (RR = 1.23, 95% CI: 1.02–1.50). Moreover, all 4 NOACs were associated with lower incidences of major venous thromboembolism compared with LMWH.ConclusionA lower risk of wound complications was detected for apixaban, while dabigatran and rivaroxaban did not increase the risk when compared with LMWH. The efficacy of 4 NOACs was broadly similar.
Brain GLP‐1 and the regulation of food intake: GLP‐1 action in the brain and its implications for GLP‐1 receptor agonists in obesity treatment
Authors: Trapp Stefan , Brierley Daniel I. 
Published: July 2021

This review considers the similarities and differences between the physiological systems regulated by gut‐derived and neuronally produced glucagon‐like peptide 1 (GLP‐1). It addresses the questions of whether peripheral and central GLP‐1 sources constitute separate, linked or redundant systems and whether the brain GLP‐1 system consists of disparate sections or is a homogenous entity. This review also explores the implications of the answers to these questions for the use of GLP‐1 receptor agonists as anti‐obesity drugs.LINKED ARTICLESThis article is part of a themed issue on GLP1 receptor ligands (BJP 75th Anniversary).

Class, partisanship and the great recession: the conflicting influences on attitudes towards inequality during economic crises
Authors: Haddon Edward 
Published: July 2021

AbstractWhile some scholars suggest that critical attitudes towards inequality follow the class gradient during recessions, others find that classes are largely unresponsive. In this article, I consider how party affiliation interacts with class to shape perceptions of inequality during a recession. I argue that it is important to look at the interplay between class and partisanship to better understand individual views towards inequality during times of economic crises. Leveraging data from the International Social Survey Programme before and after The Great Recession, I find that the recession did not raise awareness of inequality across classes. This is because party affiliation moderates the relationship differently according to class. Specifically, party affiliation is more important in shaping the inequality views for the upper class and less so for the working class. Future research needs to consider the interplay between class and politics when exploring how inequality attitudes respond to economic crises.
