Accounting development in Pakistan

This paper examines the origins, growth, and the development of accounting practices and disclosures in Pakistan and the factors that influenced them. We trace the early days of accounting in the Indian subcontinent and discuss the British colonial influence. We examine the development of accounting in Pakistan through three eras: Independence through 1971, Post 1971-1984, and 1984 to present. We describe how the colonial past and later the international financial institutions such as the Asian Development Bank and the International Monetary Fund played key roles in shaping accounting and reporting practices of the country. Pakistan's adoption of International Financial Reporting Standards as national standards has not led to improvement in the quality of financial reporting. We argue that Pakistan, even though classified as a common law country in literature, exhibits most of the properties of code law countries. We conclude that lack of investor protection (e.g., minority rights protection, insider-trading protection), judicial inefficiencies, and weak enforcement mechanisms are more critical to explaining the state of financial reporting in Pakistan than are cultural factors. This insight has policy implications for developing countries that are making efforts to improve the quality of the financial reporting of their business entities.     

Have labour practices and human rights disclosures enhanced corporate accountability? The case of the GRI framework

This paper critically evaluates Transnational Corporations’ (TNCs) claimed adherence to the Global Reporting Initiative (GRI)’s ‘labour’ and ‘human rights’ reporting guidelines and examines how successful the GRI has been in enhancing comparability and transparency. We found limited evidence of TNCs discharging their accountability to their workforce and, rather, we found evidence to suggest that disclosure was motivated more by enhancing their legitimacy. TNCs failed to adhere to the guidelines, which meant that material information items were often missing, rendering comparability of information meaningless. Instead, TNCs reported large volumes of generic/anecdotal information without acknowledging the impediments they faced in practice.     

Anthropogenic and topographic correlates of natural vegetation cover within agricultural landscape mosaics in Turkey

Natural vegetation enhances the value of agricultural landscapes for people and wildlife. However, the role of anthropogenic versus topographic factors in driving the extent of natural vegetation cover within agricultural lands at large spatial scales remains unexplored. I assessed the influence of anthropogenic and topographic variables on the extent of agricultural mosaics with high natural vegetation cover in the country of Turkey where a large extent of natural and semi-natural vegetation is maintained by traditional agriculture. GIS layers depicting human land use, elevation, slope, roads and population data were obtained and summarized at two spatial scales, within provinces and for 100 km² grid cells covering the country’s entire agricultural land area. Average farm size was also obtained at province level. Hierarchical Partitioning was conducted to determine the independent effect of anthropogenic and topographic variables on the variation in agriculture with high natural vegetation. Slope had the largest independent effect on the variation in the proportion of agricultural mosaic with high natural vegetation cover. The extent of agricultural and settlement area also explained much of the variation in natural vegetation across both grid cells and provinces. The proportion of natural vegetation increased as human population and road density decreased across grid cells and as average farm size decreased across provinces. These results suggest that while topography is the primary driver of natural vegetation cover within agricultural mosaics in Turkey, the pressures associated with urban development and agricultural industrialization may also influence the cultural and wildlife value of agricultural landscapes.     

High-Performance HR Practices,Work Stress and Quit Intentions in the Public Health Sector: Does person–organization fit matter?

Drawing on the attraction–selection–attrition (ASA) framework, this paper examines a mechanism, namely person–organization (P–O) fit, through which high-performance HR practices (HPHRPs) affect two negative employee outcomes: work-related stress and quit intentions. Using a sample of Egyptian public health sector workers, a mediation model is tested empirically using structural equation modelling. The study results show that HPHRPs positively affected P–O fit, which in turn had significant negative associations with work stress and quit intentions. P–O fit also explained a high proportion of mediation in the relationship between HPHRP and both outcomes.     

Unpacking systemic innovation capacity as strategic ambidexterity: How projects dynamically configure capabilities for agricultural innovation

Problems in agriculture and land use are increasingly recognised as complex, uncertain, operating at multiple levels (field to global value chains) and involving social, economic, institutional, and technological change. This has implications for how projects navigate complexity to achieve impact. However, few studies have systematically evaluated how project actors engage with other actors to configure capabilities and resources across multiple levels in agricultural innovation systems (AIS), from the individual to the network, to mobilise and build systemic innovation capacity. An analytical framework conceptualising the nested configuration of capabilities at multiple levels in the AIS is applied to two projects that successfully tackled agricultural and land management problems of differing complexity: (i) improving lamb survival; and (ii) sustainable land management in New Zealand. Findings indicate that innovation capacity constitutes project actors interacting with other AIS actors to configure capabilities and resources at different levels of the AIS in order to leverage positive project path dependencies and break path dependencies that are created by existing and historical capability configurations. Project actors also balance exploiting existing innovation capabilities, as well as using adaptive capability for exploring and creating new capability configurations to respond to emerging circumstances. This implies that projects should have strategic ambidexterity in terms of how they combine exploiting existing and exploring new networks to access, combine, create, or disconnect certain capabilities to address ‘capability voids’ in AIS. This requires support to projects to constantly scrutinise, through reflexive monitoring by dedicated facilitators, specific agriculture and land use policies connected to major sustainable development models (e.g. climate smart agriculture, urban farming, smart farming). The can help assess whether the AIS provides the right mix of capabilities and whether this is adequately supported by innovation policy, to realize transformative policy objectives.     

Constructing the culinary consumer: transformative and reflective processes in Italian cookbooks

This paper explores how culinary texts operate in both performative and transformative senses in relation to wider societal norms of gender and cultural capital. As such, the paper explores changes to the way in which the culinary consumer is presented in British Italian cookbooks from 1954 to 2005. Across the period, we see a shift in the gendered representation of the culinary subject, from a housewife in the period 1954–1974, to a working mother from 1975 to 1986, and most recently as male or female cook from 1987 to 2005. We also see shifts in representation of cultural capital in these same periods from learning new cooking skills, to adapting existing cooking skills to displaying skills in shopping and product selection. In charting these changing discourses, we find that whilst reflecting wider culinary culture, these cookbooks also act in a transformative sense to promote (and indeed require) specific enactments of gender and cultural capital.     

Trade-off relationship between modern agriculture and biodiversity: Heavy consolidation work has a long-term negative impact on plant species diversity

Human-driven land-use changes often cause a decline in biodiversity. Although traditional agricultural practices maintained biodiversity at high levels, recent land-use changes may have negative consequences on species composition. In this study, we examined the hypothesis that land consolidation, which is a major recent land-use change in agricultural areas, decreases plant species diversity over the long term (the so-called negative legacy). To test this hypothesis, we examined the relationships between consolidated areas and the occurrence of threatened plant species across Japan and at the prefecture scale. Twenty-three threatened plant species were selected, all of which were formerly common. Our results show that areas containing records of threatened plant species rarely experienced consolidation at whole-country and prefectural scales. Breakdown analysis showed that unconsolidated agricultural areas contained significantly more threatened species than consolidated agricultural areas. These results suggest that threatened plant species require unconsolidated agricultural areas (i.e., these species could not grow in consolidated areas). Thus, we propose that consolidation history could be used as an indicator of the potential for biodiversity recovery. We also suggest that consolidated agricultural areas should be used for food production rather than for the restoration of biodiversity, for reasons of cost efficiency.     

Economic and Household Impacts of Projected Policy Changes for the Irish Agri‐food Sector

The policy environment for the Irish agri‐food sector could change rapidly in the coming decade. A potentially positive factor will be the elimination of milk quotas in 2015, although a potentially negative factor will be further trade liberalisation and increased import competition. These changes come on top of the move to decouple direct aids to farmers in 2005 as part of the Mid‐Term Review of the EU's Common Agricultural Policy agreed in 2003. This paper examines these reforms and their impacts on the Irish economy and income distribution using a CGE model particularly rich in detail on the agri‐food sectors, differentiated household groups, and agricultural policy instruments including their links to productive factors and households. The results suggest that the past and projected changes in the policy environment have, in sum, a small positive impact on GDP and household income. However, the gains and losses are unequally distributed across sectors and household groups due to the highly differentiated distribution of support and protection. Although all households generally gain from the sequence of policy reforms in the long run, some experience strong adverse effects from particular reforms and in the medium term.
