As the elections approach, the US news industry is gearing up to cover the most crucial contest in a generation, aiming to prove it can do so without fear or favor, even as journalists come under attack from politicians, and public trust in news hovers at a historic low. While the media is flourishing in major cities, where journalists have rediscovered their purpose and built new followings, it is withering in less prosperous regions -- driving a market for fact-free, click-driven, polarizing material on social media.
Investors, platforms and media organizations themselves are beginning to address this divide, searching for ways to ensure that no one is deprived of accurately reported information.
There are bright spots: struggling trophy brands have attracted public-spirited billionaires, smaller titles are probing a non-profit model, and younger entrepreneurs are testing the power of an influence-driven, multi-platform approach. To what extent will these approaches influence the production, distribution and consumption of news in the next decade? Voters and politicians alike have become less willing to countenance views that differ from their own, a trend that many believe has led to a blurring between news and opinion.

Report a mispronounced word. In these troubled times for the full-time MBA it will be reassuring to some business schools that traditional strengths such as the brand value of the institution providing the course still count for something. However, global demand for the degree is down for the second consecutive year. Also, learn how the table is compiled. The source of the problem is the US, where demand has been declining at most schools for five straight years, according to figures compiled annually by the Graduate Management Admission Council GMACthe exam administrator.
Total MBA applications worldwide are down 6. Some 52 per cent of MBA courses covered in the survey reported declining applications compared with 40 per cent for whom numbers increased. Applicants are picking just one or two schools rather than three or four and are staying closer to home in these choices, he says.
This jars with the positive message of globalisation that business schools have been so keen to promote and reflects how the world has been influenced by the rise of populist leaders with nationalist agendas, Chowfla notes. The new number one on the FT ranking is perhaps the best-known name when people mention MBAs: Harvard Business School HBSthe architect of the case study teaching method at the heart of management tutoring.
All but one are the same as in the ranking. However, this does not mean that success is a matter of simply repeating the same formula. While there is consensus about the need for change in the full-time MBA market to counter falling demand, few can agree exactly about what needs to be done. One of the main criticisms of MBA programmes, especially at high-quality schools which make the FT ranking, has been the escalation in tuition fees, which have risen above the rate of inflation for much of the past decade.
It is not possible to judge from looking at the FT ranking list whether or not this was a wise strategy. Since these tuition fees were put in place, HBS has risen up the rankings but Chicago Booth has fallen. Other US schools are also clearly happy to let tuition fees rise further, arguing that it is inevitable given the pressure to invest in world-class teaching facilities and faculty.
The University of California at Berkeley is a publicly funded school, so its tuition fees are much lower than its US peers. The primary issue for most deans at the top US schools is the tightening of work visa requirements for foreign students over successive White House administrations and the anti-immigrant rhetoric of the current president. A group of 50 deans signed an open letter to the president, vice-president and main party leaders in the Senate and Congress in October, urging the removal of caps on the H-1B visa programme to allow more talented people to enter the country.
The solution might lie in trying to ape other parts of the world, where the MBA market is relatively strong. The notable difference here, aside from the more generous visa rules in many EU countries and the lower cost of their qualifications compared with the US, is the length of European teaching programmes, most of which last just one year rather than two.
For the 13th year, alumni of ranked schools also named it as the top choice institution from which they would recruit graduates. Diversity also improved, with 43 per cent female students and 49 per cent women on the board.
The school is also top of the research ranking, publishing the most articles by full-time staff in 50 selected academic journals between weighted by size of faculty. The school also leapt 15 places up the career progress ranking from 32nd to 17th position. The school is also top for career progress. However, its salary increase from before the MBA to three years after fell from to per cent and its value for money rank from 60 to Survey respondents praised the school for good career opportunities and personal development.
