The fast and efficient exchange of information is undeniably a competitive advantage in business. And in a fluctuating economic environment, it’s paramount. Unfortunately, in the rush to adapt to market needs, many organizations sacrifice effective communication. As priorities shift, executives may impart only the immediate goals and fail to share the rationale and strategies behind them. They may be so focused on results, they neglect to praise and reward their staff. Most of all, managers may forget that communication is a two‐way exchange – one part dialogue, one part listening.

Employee turnover at Alberto‐Culver North America, which was running at more than twice the industry average, has been halved over the past seven years and the company’s ability to attract top people from other firms has increased. Lavin Bernick describes how the turnaround has been achieved by focussing on organizational culture at the $2.25 billion manufacturer and marketer of personal‐care, speciality grocery and household products, which counts VO5 shampoo and the Sally Beauty Company among its stable.

Nobody concerned with political economy can neglect the history of economic doctrines. Structural changes in the economy and society influence economic thinking and, conversely, innovative thought structures and attitudes have almost always forced economic institutions and modes of behaviour to adjust. We learn from the history of economic doctrines how a particular theory emerged and whether, and in which environment, it could take root. We can see how a school evolves out of a common methodological perception and similar techniques of analysis, and how it has to establish itself. The interaction between unresolved problems on the one hand, and the search for better solutions or explanations on the other, leads to a change in paradigma and to the formation of new lines of reasoning. As long as the real world is subject to progress and change scientific search for explanation must out of necessity continue.

The purpose of this paper is to investigate the relationship between employee retention and job security and the impact of retention factors on the job security of nurses in public hospitals in South Africa. The retention of nurses is essential in public hospitals in South Africa. It is therefore critical that retention strategies are primed to ensure the job security of nurses.
The study is quantitative in nature, adopts a cross-sectional approach and is set within a positivist research paradigm. Pre-established questionnaires were used to collect data. Non-probability sampling was used to select a convenience sample. Questionnaires were distributed to three public hospitals in Johannesburg and 202 responses were received. The psychometric properties of the questionnaire were established through validity and reliability. Inferential and descriptive statistics were deployed to analyse data.
The study established that there is a relationship between retention factors and job security. The study further identified retention factors as predictors of job security and noted that training and development was the strongest predictor of job security amongst nurses. In addition, the study contributes towards research on retention practices of nurses from a South African perspective.
The study recommendations are diagrammatically represented. If implemented by human resource practitioners and nursing management, they are likely to enhance job security.
The study provides insights on the retention of nursing professionals in public hospitals in Gauteng and identifies retention factors which contribute most towards job security.

This paper aims to present a linear mathematical framework for modeling and optimizing road transport infrastructure. The framework assesses and optimizes performance of existing transport facility rather than relying on building new roads for the ever-increasing travel demand.
The mathematical framework is built upon a traffic model called Cell Transmission Model (CTM). CTM describes the relationship and evolution of traffic flow and concentration over space and time. The model is parsimonious and accurate in predicting traffic dynamics. More importantly, the traffic flow model is piecewise linear with which the corresponding transport facility optimization problem can be formulated as a Linear Programming (LP) problem and solved by established solution algorithm for global optimality.
We select a section on England Motorway M25 as a case study. With traffic data, we first calibrate the CTM, and we are able to produce traffic estimation with a reasonable error rate of 12 per cent. The corresponding LP then seeks an optimal ramp metering strategy that minimizes the delay on the motorway. It is shown that an optimal and practical strategy can be derived which reduces the motorway delay by 10 per cent without significantly hurting the surrounding connectors.
Instead of the tedious microscopic models used by many traditional tools, the underlying CTM is parsimonious and reliable. The tools developed herein are based upon plausible traffic theory and will be accessible for a wide range of users. The LP formulation can be easily implemented and solved for optimal and practical control strategies for real-world transport networks by using existing computer software (CPLEX) within reasonable computational time. The present work will certainly contribute to the sustainable development of transport facility.

A research and development project disseminated ecological technologies to approximately 3,250 vegetable farmers through farmer field schools (FFS) in four districts of Bali and East Java provinces of Indonesia. This article aims to assess the economic sustainability of vegetable production after FFS participation.
A survey randomly sampled 500 farmers, comprised of FFS participants (50%) and non-FFS participants (50%). Based on 1,000 farm operations, this analysis employed input-saving technology as the fundamental model examined using the double-difference method. Simultaneous reduction of agrochemicals and improvement of productivity represent indicators of economic sustainability.
Results indicate that pesticide use decreased without jeopardising farm productivity; moreover, vegetable production increased. These findings indicate that the ecological technologies transferred through FFS significantly improved economic sustainability performance.
This study purposively selected farmers who grew tomato and chilli. Thus, the outcomes are not generalisable to other crops.
FFS continues to be an effective method for transferring agricultural technologies to farmer communities. Policymakers are recommended to use FFS for disseminating beneficial and sustainable technologies to broader agricultural communities.
The adoption of ecological technologies provides positive economic and ecological milieus.
This study employs a double-differences approach to verify input-saving technological progress. Therefore, the performance of economic sustainability attributable to the project intervention is theoretically justified.
