The Relationship

This article first provides a critical scoping review of empirical literature on the relationship between urban structure and travel in China. The review finds that residential suburbanization alone increases travel, polycentric development has mixed effects, and jobs–housing balance reduces travel. Second, this article compares the empirical findings of the urban structure–travel relationships in China with those observed in other countries, and it identifies contextual factors that can explain the differing relationships in China. We suggest that future research improve data and methodology and broaden the research scope to investigate the complex mechanisms that affect the urban structure–travel relationship in China.

Abstract Background Older adults (≥50 years) represent the fastest-growing population of people who use cannabis, potentially due to the increasing promotion of cannabis as medicine by dispensaries and cannabis websites. Given healthy aging and cannabis use are both associated with cognitive decline, it is important to establish the effects of cannabis on cognition in healthy aging. Objective This systematic scoping review used preferred reporting items for systematic reviews and meta-analyses guidelines to critically examine the extent of literature on this topic and highlight areas for future research. Method A search of six databases (PubMed, EMBASE, PsycINFO, Web of Science, Family and Society Studies Worldwide, and CINAHL) for articles published by September 2019, yielded 1,014 unique results. Results Six articles reported findings for older populations (three human and three rodent studies), highlighting the paucity of research in this area. Human studies revealed largely null results, likely due to several methodological limitations. Better-controlled rodent studies indicate that the relationship between ∆9-tetrahydrocannabinol (THC) and cognitive function in healthy aging depends on age and level of THC exposure. Extremely low doses of THC improved cognition in very old rodents. Somewhat higher chronic doses improved cognition in moderately aged rodents. No studies examined the effects of cannabidiol (CBD) or high-CBD cannabis on cognition. Conclusions This systematic scoping review provides crucial, timely direction for future research on this emerging issue. Future research that combines neuroimaging and cognitive assessment would serve to advance understanding of the effects of age and quantity of THC and CBD on cognition in healthy aging.

Research Questions

Action sports have increased in popularity, particularly over the past two decades. Research in the area has also proliferated, as multiple disciplinary perspectives and theoretical and conceptual frames have been applied to understanding and exploring a host of research questions concerning action sports culture, contexts and participants. However, despite this flurry of research activity, not much is known empirically about the learning of action sport participants, and few studies have focused specifically on learning in action sports. A scoping review was, therefore, conducted with the aim of synthesising the work that has been undertaken, and mapping future research agendas. Informed by Arksey and O’Malley’s six-stage framework, leading sports and education databases and Google Scholar were searched for empirical literature on learning in action sports published before July 2018. After the results were screened and relevant studies identified, data were extracted and analysed using a frequency and thematic analysis to form both a descriptive and thematic summary. A total of 78 empirical studies both from the peer-reviewed and grey literature were included in the scoping review. The frequency analysis concerned information on publication year, academic field, study design, study tools, sport and population. The thematic analysis led to the development of five main themes, addressing learning in social, physical, cultural, and cognitive/psychological contexts and via various forms of feedback. The majority of articles on learning in action sports were published from 2010 onward, suggesting a growing interest in the area. More theses/dissertations resulted in peer-reviewed publications; however, less than half of all reviewed journal articles were published in education/pedagogy journals. Theoretical and conceptual frameworks were rarely explicitly referenced and/or lacked clarity. There was consensus that learning in action sports is largely informal and self-regulated. With the increasing professionalisation of many action sports and their inclusion in international competition events and also in national curricula, an increase in more formalised learning is predicted. Finally, learning in action sports can be highly individualistic but only a few studies acknowledged this. A greater variety of research questions and methodologies, and more work across disciplinary boundaries will assist in the generation of new knowledge.

Code Changes

A city is an open complex system. It should change in order to survive. Besides the need to change there is another one – to preserve stability of a valuable spatial structure. Two contradictory needs can create a problem, which is hard to solve. Concepts of urban genotype and phenotype help integrating both of the two above-mentioned needs. The same genotype can be expressed in different forms thus creating preconditions for evolution of an urban structure. On the basis of historical analogues, a conclusion was made that it is possible to describe an urban genotype in a utilitarian form in the article. The described research focuses on some aspects of urban genotype and investigation of code changes. As an experimental site for research, Kaunas downtown area was selected. This area is of crucial importance for preservation of Kaunas identity, which – at least at first glance – was protected from significant architectural and urban changes during the Soviet era… Results of the investigation reveal revolutionary changes of the genotype of the investigated area despite the fact that the street network and urban morphotype did not change much. It confirms the complex nature of the urban spatial structure and potential presence of the “butterfly effect”. Santrauka Miestas – atvira, kompleksiška sistema, kuri turi keistis tam, kad išliktų. Poreikis keistis ir išsaugoti miesto savitumui svarbias erdvines jo charakteristikas dažnai verčia rinktis vieną iš dviejų: kaitą ar stagnaciją. Urbanistinio genotipo ir fenotipo koncepcija leidžia išspręsti minėtą dilemą: keičiantis formai urbanistinis kodas ar genotipas gali išlikti nepakitęs ir taip užtikrinti evoliucinę urbanistinės struktūros kaitą. Straipsnyje, remiantis istoriniais analogais, teigiamai įvertinus urbanistinio kodo utilitaraus užrašymo galimybes, pagrindinis dėmesys skiriamas kai kuriems kodo aspektams tirti ir jų kaitai įvertinti. Kaip tyrimų poligonas naudojamas istorinis Kauno centras – miesto savasčiai svarbi ir architektūriniu požiūriu radikaliai nepakeista miesto dalis. Tyrimų rezultatai atskleidžia įvykusius didelius teritorijos urbanistinio genotipo pokyčius ir kartu patvirtina vieną iš tyrimo pradžioje padarytų prielaidų: miestui kaip kompleksiškai sistemai gali būti būdingas „drugelio efektas“ – ir nedideli pakeitimai fenotipe gali sukelti gana dideles mutacijas genotipe.

PurposeThe purpose of this state-of-the-art review is to explore the empirical literature on federal intervention of police under 42 USC Section 14141.Design/methodology/approachA five-stage scoping review of the empirical literature related to 14141 was conducted through searches of scholarly databases and gray literature.FindingsThis scoping review revealed 21 empirical studies of 14141 published between 2002 and 2020 in criminal justice, criminology, legal and gray literature. Researchers employed various methodologies and designs to study 14141 reflecting the complexity of evaluating a multistage and multi-outcome federal intervention of police. The success of 14141 to reform police agencies is mixed. The empirical evidence suggests that application of this law is fraught with trade-offs and uncertainties including de-policing, increased crime and organizational difficulties in sustaining reform. Overall, more research would assist in understanding the efficacy of this federal mechanism of police accountability and reform.Originality/valueThis review is the first synthesis of the empirical literature on 14141. In consideration of the current national police crisis, findings help illuminate both what is known about federal intervention and areas for future research.

The Relationship

Emerging research suggests that a relationship exists between breastfeeding and postpartum depression; however, the direction and precise nature of this relationship are not yet clear. The purpose of this paper is to provide an overview of the relationship between breastfeeding and postpartum depression as it has been examined in the empirical literature. Also, the potential mechanisms of action that have been implicated in this relationship are also explored. PubMed and PsycINFO were searched using the keywords:breastfeedingwithpostpartum depression, perinatal depression, postnatal depression. Results of this search showed that researchers have examined this relationship in diverse ways using diverse methodology. In particular, researchers have examined the relationships between postpartum depression and breastfeeding intention, initiation, duration, and dose. Due to a number of methodological differences among past studies we make some recommendations for future research that will better facilitate an integration of findings. Future research should (1) use standardized assessment protocols; (2) confirm diagnosis through established clinical interview when possible; (3) provide a clear operationalized definition for breastfeeding variables; (4) clearly define the postpartum period interval assessed and time frame for onset of symptoms; (5) be prospective or longitudinal in nature; and (6) take into consideration other potential risk factors identified in the empirical literature.

The Relationship

In the daily work of criminal justice, the relationship between plea decision-making and sentencing is important. Meanwhile in the academic and policy literatures, it is one of the most controversial. This essay appraises the international empirical literature and the moral arguments surrounding this plea-dependent (guilty/not guilty) “sentence differential.” Sentence differential is the morally neutral term used here to denote practices variously termed as “sentence discount,” “trial tax/penalty,” “guilty plea discount/reduction,” and “sentence bargain/negotiation.” Section II analyzes whether the sentence differential undermines the presumption of innocence. Section III investigates whether the sentence differential violates legal equality. Section IV assesses the three main justifications for the differential. Section V scrutinizes measurement of the sentence differential. Section VI proposes an agenda for future research, including the need for deeper research into the experiences of and interpretations by defendants of the justice process.

The audit committee is a fundamental and prerequisite tool for fulfilling board’s monitoring role of ensuring transparency, financial and managerial efficiency. Therefore, it has been applied to address perceived governance failure. This paper aims to critically review the previous literature on the relationship between audit committee diversity as a major corporate governance mechanism and corporate voluntary disclosure reporting (CVDR) with a change in the regulatory regime as moderation variable. This review specifically evaluates theoretical and empirical literature related to audit committee diversity such as independence, financial expertise, accounting expertise; and CVDR in order to highlight some important areas of gaps for future research in this field. It also, emphases the need for a more qualitative method for better understanding of the relationship. This paper proposes that examining the moderating influence of the change of the regulatory regime with regard to CVDR would provide more insight into the link between audit committee diversity and CVDR. The policy implication of the study is also discussed. Lastly, the paper stresses the importance of future studies linking audit committee diversity and CVDR, which are quite scanty the existing literature.

The Relationship

Voluntary disclosure (VD) is considered potentially important for efficient functioning of the capital market as it communicates firms’ performance and governance to shareholders and potential investors, which boost their confidence. This article attempts to provide a brief conceptual framework of VD and corporate governance (CG), and also reviews the empirical literature dealing with relationship between them. To this end, the article uses systematic electronic literature search method, which takes into account 65 empirical studies published over the period 1998–2018. An investigation of empirical findings points to some factors that may have contributed toward the apparent inconsistent findings observed to date. In particular, the article focuses on two intervening factors for variation of results—such as CG system and measurement of explanatory variables. The findings suggest that studies mostly from Anglo-Saxon system (ASS) show complementary relationship between different attributes of CG with VD, whereas in case of communitarian system, studies mostly depict an insignificant impact of CG attributes on VD except for few studies showing their positive/negative impact on VD. However, in case of emerging market system (EMS), some studies show substitutive relationship between board independence (BI) and VD while other CG attributes such as board size (BS), (GD), and audit committee independence (ACI) in most of the studies complement VD supporting the resource-based perspective. Furthermore, the association of ownership structure (OS) and role duality (RD) with VD is mixed. Another factor, which is considered to be added to variation of results, is measurement of explanatory variables whereby albeit studies employed same concepts, operational definition of variables intervenes into the relationship between CG and VD. The findings of this article provide some deeper insights about the complementary and substitutive relationships between CG and VD by integrating diverse empirical findings under different research contexts. Future research can extend to analyze some other institutional factors like investors’ protection rights and legal enforcement, which might also have played some role in influencing the relationship between CG and VD. Furthermore, it is also evident from the review that BS and BI are the most commonly studied CG attributes in relation to VD, whereas attributes like GD and ACI, despite their theoretical relevance and practical importance are least studied in relation to VD, thus signaling the need to focus on these attributes in future studies.

Summarising and synthesising the evidence on cricket health and wellbeing can help inform cricket stakeholders and navigate future research directions. The purpose of this study was to investigate the relationship between cricket participation, health and wellbeing at all ages and playing standards, and identify research gaps in the existing literature. A scoping review was performed from inception to March, 2020. Studies were included if they assessed a construct related to health and/or wellbeing in cricketers, available in English. 219 articles were eligible. Injury incidence per 1,000 player exposures ranged from 1.8-5.7 injuries. 48% of former cricketers experienced persistent joint pain. However, former cricketers reported greater physical activity levels and mental-components of quality of life compared to the general population. Heat injury/illness and skin cancer are concerns and require further research. Cricket participation is associated with an inherent injury risk, which may have negative implications for musculoskeletal health in later life. However, cricket participation is associated with high quality of life which can persist after retirement. Gaps in the literature include prospective studies on health and wellbeing of cricketers, female cricketers, injury prevention strategies, and the impact of cricket participation on metabolic health and lifetime physical activity.
