Strategy not tactics drives aggregate planning

The aggregate planning model supposedly shows how manufacturers cope with seasonally biased sales. Unfortunately, industry has failed to embrace any of the sophisticated algorithms that were developed to solve the corresponding resources allocation problem. This paper reveals why such methods have proven so unattractive. Aggregate planning is a chimera. In practice, planners construct the master production schedule directly, in line with a preferred production strategy. A “chase” plan is the most popular choice. When this option proves infeasible, management plumps for another predetermined strategy. The resultant stockpiling brings certain financial risks. However, companies take various measures to reduce their exposure.

Predicting IHRM strategy and practice decisions : development of the IHRM orientation typology

International human resource management (IHRM) is becoming increasingly fundamental to organisational success, as globalisation forces demand organisations to design and implement a global strategy. One of the most critical choices faced by IHRM practitioners is whether and when an organisation should adapt its human resource policies and practices to the local context (localisation). A typology of International Human Resource Management Orientations (IHRMO) that clarifies what IHRMO’s are and what they entail is developed from a review of the literature on localisation and globalisation, convergence and divergence and Perlmutter’s management typology. Additionally, two theoretical models are developed that predict which IHRM orientation identified in the typology should be adopted. The article takes a step towards elucidating effective IHRM strategy and practice decision-making by showing that culture and institutional pressures, amongst other tings, do make a difference.

Transacting with citizens: Australian government policy, strategy and implementation of online tax lodgement

Many governments have shown leadership in encouraging their citizenry to conduct transactions on-line. The policies that underpin these initiatives refer to a blend of civic benefits and efficiency goals. They combine the rhetoric of customer service with social shaping through ‘government as model user’ and procedures that require online activities. Many initiatives are described as ‘electronic service delivery’, terms that indicate an intention to provide much more than an additional channel for government interaction with citizens. Australia, as an innovator in eGovernment is a good example of this approach and its national government has specified policy goals for its online strategy. In this paper we examine the case of one Australian online delivery initiative, electronic tax lodgement (e-tax) and consider how well that initiative has met the policy goals of the government. Combining insights from Rogers’ Diffusion of Innovation theory and political analysis, we outline potential difficulties that governments face in implementing ESD initiatives. Our conclusion from this case study is that the provision of good technology is only a small part of the ESD challenge. It shows how success of an ESD implementation may yield contradictory outcomes in terms of overall eGovernment strategies. This case highlights the need for long-term
implementation plans and integration of initiatives with broader government strategy.

The relationship between channel metrics, strategy and marketing performance

The role of marketing channels is to implement marketing strategy. The difficulty of channel strategy is compounded by the emergence of e-channels and the need to integrate e-channels into traditional or “bricks and mortar” channels (Rowley 2002). As a result, managing performance across a greater number of channels with diverse characteristics is more difficult.

Organization and marketing performance is to some degree a function of the quality of channel implementation and particularly channel performance measurement. The channels literature suggests a “channel performance metric paradox”. Approaches to channel performance metrics have been mutually orthogonal or even negatively correlated. (Jeuland & Shugan 1983; Lewis & Lambert 1991; Larson & Lusch 1992). This paradox implies that it is impossible for all channel performance metrics to be maximized simultaneously and tradeoffs exist.

This paper proposes a research model and propositions which extend previous research and attempts to reconcile this “channel performance metric paradox”. The model assumes that testing the relationship between the Miles and Snow strategy types and a comprehensive range of channel performance metrics may explain this paradox. Previous implementation performance research has focused more on the Porter strategies rather than the Miles and Snow strategy types.

The relationship between business unit strategy and the use of market research

A study of 42 Australian marketing managers was conducted linking strategy to the use of market research, with a measure known as USER. It was expected that the Miles and Snow strategic typology with its greater emphasis on internal organisational culture, practices and structure would be more powerful than the Porter strategic dimensions in determining the motivation and actual use of market research. The findings showed that neither strategic typology was superior in predicting market research practice. In the study, the USER characteristics most linked to strategy were “the misuse of market research for political purposes” and “internal improvements based on market research.” Two other USER factors “rational use of market research findings” and “use of market research to confirm decisionmaking” were not found to be related to marketing strategy.

Aligning marketing strategy and marketing implementation for marketing performance

The purpose of this paper is to examine the differences between “pure” and “mixed” marketing strategies in terms of implementation practices and performance. The strategies compared use the Miles and Snow (1978) typology to develop Pure Prospectors, Pure Defenders, Reactors and Mixed strategies the latter strategy type being similar to Analysers.

Previous strategy type implementation research has used debatable strategy classification methodologies and has not isolated “pure” marketing strategies. The purpose of this paper is to clearly identify and separate “pure” marketing strategies from “mixed” strategies.

In terms of strategy implementation a key finding was that the Miles and Snow implementation recommendations made in the 1970’s no longer appear to be appropriate in the 2000’s This appears to be the case because no need to align human resource practices and organisational structure with strategy was apparent in our findings.

In terms of strategy performance differences a key finding was that Pure Prospectors outperformed Reactor strategies in terms of new markets, sales growth, new products and market share. However, the financial costs of investing in new markets and new products undertaken by the aggressive Pure Prospector strategies results in only similar ROI performance to other strategies. This is consistent with the concept of performance equifinality.

Nucleic acid vaccines: tasks and tactics

There are no adequate vaccines against some of the new or reemerged infectious scourges such as HIV and TB. They may require strong and enduring cell-mediated immunity to be elicited. This is quite a task, as the only known basis of protection by current commercial vaccines is antibody. As DNA or RNA vaccines may induce both cell-mediated and humoral immunity, great interest has been shown in them. However, doubt remains whether their efficacy will suffice for their clinical realization. We look at the various tactics to increase the potency of nucleic acid vaccines and divided them broadly under those affecting delivery and those affecting immune induction. For delivery, we have considered ways of improving uptake and the use of bacterial, replicon or viral vectors. For immune induction, we considered aspects of immunostimulatory CpG motifs, coinjection of cytokines or costimulators and alterations of the antigen, its cellular localization and its anatomical localization including the use of ligand-targeting to lymphoid tissue. We also thought that mucosal application of DNA deserved a separate section. In this review, we have taken the liberty to discuss these enhancement methods, whenever possible, in the context of the underlying mechanisms that might argue for or against these strategies.

Differences in foraging strategy and maternal behaviour between two sympatric fur seal species at the Crozet Islands

Marine top-predators such as marine mammals forage in a heterogeneous environment according to their energetic requirements and to the variation in environmental characteristics. In this study, the behaviour of breeding females in 2 sympatric fur seal species, Antarctic fur seal Arctocephalus gazella and Subantarctic fur seal A. tropicalis, was investigated in relation to foraging effort. Foraging effort was hypothesised to be greater in Antarctic fur seal than in Subantarctic fur seal due to their shorter lactation period. Using satellite telemetry, time-depth recorders and satellite images of sea-surface temperature and chlorophyll a concentration, the foraging grounds, the at-sea activity budgets and the environmental features were determined for both species breeding on the Crozet Archipelago. Foraging cycle duration was similar for the 2 species, and the seals exhibited similar at-sea activity budgets. Only the proportion of time spent at sea was higher in Antarctic fur seals. Separate foraging areas were identified for the 2 species. Antarctic fur seal distribution was related to bathymetric features, while we did not find any direct relationship between chlorophyll a concentration and seal foraging areas. Our results suggest that Antarctic fur seals tend to respond to the higher needs of their pups by having a higher foraging efficiency and concentrating their foraging activity in the most productive areas.

Pacing strategy and high-intensity cycling performance

This thesis found that a brief maximal acceleration, followed by a steady effort thereafter is the most effective pacing strategy for intense, short-term cycling performance. This strategy leads to an increase in aerobic energy supply early in exercise, which contributes to a faster speed throughout the race.
