An evaluation u-turn: From narrow organisational objectives to broad accountability

The development of evaluation scholarship progresses, but the slow and incremental steps taken are largely refinements on a direction of thinking that has become established and virtually taken for granted. Most frameworks and models which have gained recognition in the academy and practice follow programme logic methodology. They also point to the achievement of organisational objectives as being the principal, but not always sole, purpose of public relations programmes. The achievement of organisational objectives has therefore been the focus of evaluation.Parallel, to this, a second strand of thinking in the scholarship and practice has questioned the assumption that the meeting of organisational objectives is paramount and whether organisations alone should determine the measures of success. Other perspectives such as stakeholder judgements of success and the obligation of organisations to meet societal expectations have been discussed as legitimate ways in which to evaluate programmes and activities.This paper takes forward this second strand by proposing that the evaluation debate should be ‘flipped’. Instead of organisational objectives being a primary denominator for evaluation, the paper proposes that whether organisations discharge their accountabilities to stakeholders and society is of equal, if not more weight. An organisation will succeed only if it sustains its licence to operate. To achieve that it has to meet the reasonable expectations that licence-givers have and to obtain their active consent to support its actions. The key questions for public relations are therefore: who/what holds us to account? What are their expectations? How are their expectations fulfilled? Drawing on the management and public relations literature to answer these questions, the paper calls for a radical ‘turn’ from the prevailing thinking, which the authors suggest is more about public relations explaining and justifying itself, towards a model that aligns with contemporary management thinking and practice.The paper proposes a model and process that provides a way forwards based not only on organisational aspirations, but on a hierarchy of obligations: to society, stakeholders, the organisation, and to the professional function which runs campaigns. It offers a principles based evaluation approach. In doing so, it takes the evaluation debate in a new direction and thereby adds to theory-building. It also offers a new way forwards for the practice which has become increasingly mired in developing more comprehensive lists of indicators and metrics and expanding taxonomies of evaluation terms.     

Spontaneous plant colonization and bird visits of tropical extensive green roof

Green roofs can contribute to enrichment and conservation of urban ecology. An experimental green roof was established in humid-tropical Hong Kong to monitor over two years its spontaneous colonization by plants and bird visits. Some 94 voluntary vascular plant species from 26 families and 76 genera were established, with propagules brought mainly by birds and wind and secondarily inherited from soil seed bank. Plant species composition changed dynamically during the study period. They fall into three groups, namely dominant ruderal (herbaceous and sub-shrub) as surrogate of early-stage local grassland ecosystem succession, arboreal (trees and shrubs), and hygrophilous herb. Progressive increase in vegetation cover was accompanied by changes in species diversity and evenness. In addition, 16 bird species from 8 families and 14 genera were recorded. Ten species were residents and the six migrant species were winter visitors. Their food preference was mainly omnivore and insectivore. Winter and the second year encountered higher species richness, diversity, and evenness. Most vegetation parameters correlated positively with avian community indexes, signifying provision of sustenance by green-roof ecosystem to birds. Vegetation coverage correlated negatively with avian abundance, due to shunning by the abundant ground-foraging Tree Sparrow. Both local common ruderal plant species and common urban bird species can successfully establish and reproduce on the extensive green roof, confirming potentials for urban ecology and biodiversity enhancement and conservation even in densely-developed urban areas. The successful nurturing of naturalistic green roof offers new opportunities for green roof design that deviates from the predominant cultivated-horticultural approach.     

Empirical characteristic function tests for GARCH innovation distribution using multipliers

Goodness-of-fit tests for the innovation distribution in GARCH models based on measuring deviations between the empirical characteristic function of the residuals and the characteristic function under the null hypothesis have been proposed in the literature. The asymptotic distributions of these test statistics depend on unknown quantities, so their null distributions are usually estimated through parametric bootstrap (PB). Although easy to implement, the PB can become very computationally expensive for large sample sizes, which is typically the case in applications of these models. This work proposes to approximate the null distribution through a weighted bootstrap. The procedure is studied both theoretically and numerically. Its asymptotic properties are similar to those of the PB, but, from a computational point of view, it is more efficient.     

Cost performance of public infrastructure projects: the nemesis and nirvana of change-orders

The cost performance of a wide range of public sector infrastructure projects completed by a contractor are analysed and discussed. Change-orders after a contract to construct an asset was signed were, on average, found to contribute to a 23.75% increase in project costs. A positive association between an increase in change orders and the contractor’s margin were identified. Taxpayers pay for this additional cost, while those charged with constructing assets are rewarded with an increase in their margins. As the public sector embraces an era of digitisation, there is a need to improve the integration of design and construction activities and engender collaboration to ensure assets can be delivered cost effectively and future-proofed. The research paper provides empirical evidence for the public sector to re-consider the processes that are used to deliver their infrastructure assets so as to reduce the propensity for cost overruns and enable future-proofing to occur.     

Estimating reference ranges from stratified two-stage samples

We present methodology for estimating age-specific reference ranges by using data from two-stage samples. On the basis of the information obtained in the first stage, the initial sample is stratified and random subsamples are drawn from each stratum, where the selection probabilities in this second-stage sampling may be different across strata in the population. The variable for which the reference ranges are to be established is measured at the second phase. The approach involves maximum likelihood estimation of the parameters of the age-specific distributions and separate estimation of the population stratum probabilities. These are combined to yield estimates of the quantiles of interest. The issue of variance estimation for the estimated quantiles is also addressed. The methodology is applied to the estimation of reference ranges for a cognitive test score in a study of non-demented older Japanese-Americans.     

How Can You Tell when a Goldfish Cries? Finding the Words in Therapeutic Stories with Children

Stories provide one way to say the unspeakable. Drawing on systemic, constructionist and narrative ideas, this paper offers a commentary upon the development of a therapeutic story for a seven year old child and her mother.     

Single Session Social Work in Hospitals

This paper reports on three complementary research studies that set out to examine the incidence and nature of single sessions in hospital social work practice. The first study was a data‐mining exercise that used statistics recorded by practitioners in nine public hospitals over a 12‐month period to establish the extent of single session work, the clinical areas in which it occurred, and the types of issues it covered. This quantitative information was enhanced with the qualitative findings of the two subsequent studies: the first with hospital social workers; and the second with singlesession clients. We concluded that single session work has not been sufficiently acknowledged in social work education and literature, and that it needs to become a more legitimate part of social work practice and training. At best, it represents social work at its highest level of skill, requiring expertise in quickly building rapport, assessment, and knowledge about sources of practical aid and information.     

Intergenerational Mobility of the Mexican‐Origin Population in California and Texas Relative to a Changing Regional Mainstream

We combine two approaches to gauge the achievements of the Mexican‐origin second generation: one the intergenerational progress between immigrant parents and children, the other the gap between the second generation and non‐Latino whites. We measure advancement of the Mexican‐origin second generation using a suite of census‐derived outcomes applied to immigrant parents in 1980 and grown children in 2005, as observed in California and Texas. Patterns of second‐generation upward mobility are similar in the two states, with important differences across outcome indicators. Assessments are less favorable for men than women, especially in Texas. We compare Mexican‐Americans to a non‐Latino white reference group, as do most assimilation studies. However, we separate the reference group into those born in the same state as the second generation and those who have migrated in. We find that selective in‐migration of more highly‐educated whites has raised the bar on some, not all, measures of attainment. This poses a challenge to studies of assimilation that do not compare grown‐children to their fellow natives of a state. Our model of greater temporal and regional specificity has broad applicability to studies guided by all theories of immigrant assimilation, integration and advancement.     

The Management of Information and Managers in Subsidiaries of Multinational Corporations

A key challenge facing multinational corporations (MNCs) is how to encourage the development of firm specific advantages throughout the network of subsidiaries while maintaining global coherence. As a result, a critical task for top managers in the MNC is to structure the relationship between headquarters and subsidiaries. Thus, headquarters' control of subsidiary behaviour and performance becomes a central integrating function in the MNC. We examine first the relationship between the nationality of the MNC headquarters and its information management, namely the key performance metrics utilized by the parent to evaluate subsidiary performance. Second, we investigate the relationship between the MNC nationality and its management of managers, specifically, the transfer of parent company nationals and corporate acculturation. These questions are investigated in a study of MNC subsidiaries located in Australia, Ireland and Singapore. Our data provide strong evidence that MNCs of all nationalities place the greatest emphasis on financial metrics compared to other performance metrics. Moreover, there are differences in the degree of emphasis on performance metrics across MNC nationality. We found that Japanese and German MNCs place significantly less emphasis on financial measures than US and UK MNCs. Our hypotheses relating to the management of managers were also supported by the data. In comparison with all other MNC nationalities, Japanese MNCs place greater emphasis on the transfer of Japanese managers to overseas subsidiaries and less emphasis on corporate acculturation. While some researchers have argued that management control has become more isomorphic as a result of globalization, our results show that companies from different nationalities diverge in their practices.
