Three Coupled Model Intercomparison Project Phase 5 models involved in the G4 experiment of the Geoengineering Model Inter-comparison Project (GeoMIP) project were used to investigate the impact of stratospheric aerosol injection (SAI) on the mean surface air temperature and precipitation extremes in Africa.

This impact was examined under G4 and Representative Concentration Pathway (RCP) 4.5 scenarios on the total precipitation, the number of rainy days (RR1) and of days with heavy rainfall (R20 mm), the rainfall intensity (SDII), the maximum length of consecutive wet (CWD) and dry (CDD) days and on the maximum rainfall in five consecutive days (Rx5day) across four regions: Western Africa (WAF), Eastern Africa (EAF), Northern Africa and Southern Africa (SAF).

During the 50 years (2020–2069) of SAI, mean continental warming is −0.40°C lower in G4 than under RCP4.5. During the post-injection period (2070–2090), the temperature continues to increase, but at a lower rate (−0.19°C) than in RCP4.5. During SAI, annual rainfall in G4 is significantly greater than in RCP4.5 over the high latitudes (especially over SAF) and lower over the tropics. The termination of SAI leads to a significant increase of rainfall over Sahel and EAF and a decrease over SAF and Guinea Coast (WAF).

Compared to RCP4.5, SAI will contribute to reducing significantly regional warming but with a significant decrease of rainfall in the tropics where rainfed agriculture account for a large part of the economies. After the SAI period, the risk of drought over the extratropical regions (especially in SAF) will be mitigated, while the risk of floods will be exacerbated in the Central Sahel.

To meet the Paris Agreement, African countries will implement mitigation measures to contribute to keep the surface air temperature below 2°C. Geoengineering with SAI is suggested as an option to meet this challenge, but its implication on the African climate system needs a deep investigation in the aim to understand the impacts on temperature and precipitation extremes. To the best of the authors’ knowledge, this study is the first to investigate the potential impact of SAI using the G4 experiment of GeoMIP on temperature and precipitation extremes of the African continent.

Dementia in older persons with learning disabilities is a growing concern for all those involved in their care. There is at present no effective treatment, but the importance of current drug treatments is reviewed. Developments in drug treatments for dementia remain an active area of ongoing research.

The proliferation of workstations throughout the engineering and manufacturing industries generally means that the tremendous amounts of data that are becoming available need to be managed in an efficient and integrated way. Examines the organizational, financial and technical implications involved in the implementation of accessing and sharing information and the various systems available to enable this to be achieved successfully.

Introduction Effectively managing your technical information does not just mean knowing where the documents are stored — it means effectively managing your products. It is fast becoming the key to managing time‐to‐market, quality, and costs as well. Managing the technical information about products has become known as Product Information Management (PIM). This article discusses the organisational, financial and technical implications involved in the successful management of product information, and the enabling of organisational and technical interoperability.

In the current business environment, more uncertain than ever before, understanding consumer behavior is an integral part of an organization's strategic planning and execution process. It is the key driver for becoming a market leader. Therefore, it is important that all processes in business are customer centric. Marketers need to harness big data by engaging in data driven-marketing (DDM) to help organizations choose the “right” customers, to “keep” and “grow” them and to sustain “growth” and “profitability”. This research examines DDM adoption practices and how companies can aim to enhance shareholder value by bringing about “customer centricity”.

An online survey conducted in 2016 received 180 responses from junior, middle and senior executives. Of the total responses, 26% were from senior management, 39% from middle management and the remaining 35% from junior management. Industries represented in the survey included retail, BFSI, healthcare and government, automobile, telecommunication, transport and logistics and IT. Other industries represented were aviation, marketing research and consulting, hospitality, advertising and media and human resource.

Success of DDM depends upon how well an organization embraces the practice. The first and foremost indicator of an organization's commitment is the extent of resources invested for DDM. Respondents were divided into four categories; Laggards, Dabblers, Contenders and Leaders based on their “current level of investments” and “willingness to enhance investments” soon.

With storming digital age and the development of analytics, the process of decision-making has gained significant importance. Judgment and intuition too are critical to the process. Choosing an appropriate action cannot be done strictly on a rational basis.

The results of the study offer interesting implications for managing the growing sea of data. An iterative and incremental approach is the need of the hour, even if it has to start with baby steps, to invest in and reap the fruits of DDM. The intention to use any system is always dependent on two primary belief factors: perceived usefulness and perceived ease of use; however, attitudes and social factors are equally important.

There is a dearth of knowledge with regards to who is and is not adopting DDM, and how best big data can be harnessed for enhancing effectiveness and efficiency of marketing budget. It is, therefore, imperative to build a knowledge base on DDM practices, challenges and opportunities. Better use of data can help companies enhance shareholder value by bringing about “customer centricity”.

This issue is a selected bibliography covering the subject of leadership.

In the last four years, since Volume I of this Bibliography first appeared, there has been an explosion of literature in all the main functional areas of business. This wealth of material poses problems for the researcher in management studies — and, of course, for the librarian: uncovering what has been written in any one area is not an easy task. This volume aims to help the librarian and the researcher overcome some of the immediate problems of identification of material. It is an annotated bibliography of management, drawing on the wide variety of literature produced by MCB University Press. Over the last four years, MCB University Press has produced an extensive range of books and serial publications covering most of the established and many of the developing areas of management. This volume, in conjunction with Volume I, provides a guide to all the material published so far.

In its passage through the Grand Committee the Food Bill is being amended in a number of important particulars, and it is in the highest degree satisfactory that so much interest has been taken in the measure by members on both sides of the House as to lead to full and free discussion. Sir Charles Cameron, Mr. Kearley, Mr. Strachey, and other members have rendered excellent service by the introduction of various amendments; and Sir Charles Cameron is especially to be congratulated upon the success which has attended his efforts to induce the Committee to accept a number of alterations the wisdom of which cannot be doubted. The provision whereby local authorities will be compelled to appoint Public Analysts, and compelled to put the Acts in force in a proper manner, and the requirement that analysts shall furnish proofs of competence of a satisfactory character to the Local Government Board, will, it cannot be doubted, be productive of good results. The fact that the Local Government Board is to be given joint authority with the Board of Agriculture in insuring that the Acts are enforced is also an amendment of considerable importance, while other amendments upon what may perhaps be regarded as secondary points unquestionably trend in the right direction. It is, however, a matter for regret that the Government have not seen their way to introduce a decisive provision with regard to the use of preservatives, or to accept an effective amendment on this point. Under existing circumstances it should be plain that the right course to follow in regard to preservatives is to insist on full and adequate disclosure of their presence and of the amounts in which they are present. It is also a matter for regret that the Government have declined to give effect to the recommendation of the Food Products Committee as to the formation of an independent and representative Court of Reference. It is true that the Board of Agriculture are to make regulations in reference to standards, after consultation with experts or such inquiry as they think fit, and that such inquiries as the Board may make will be in the nature of consultations of some kind with a committee to be appointed by the Board. There is little doubt, however, that such a committee would probably be controlled by the Somerset House Department; and as we have already pointed out, however conscientious the personnel of this Department may be—and its conscientiousness cannot be doubted—it is not desirable in the public interest that any single purely analytical institution should exercise a controlling influence in the administration of the Acts. What is required is a Court of Reference which shall be so constituted as to command the confidence of the traders who are affected by the law as well as of all those who are concerned in its application. Further comment upon the proposed legislation must be reserved until the amended Bill is laid before the House.
