Section C
What a lovely place Xerox is to work Kim Moloney, a client services
executive, can’t say enough nice things about her employer. ‘It’s a very special
environment,’ she says. ‘People describe Xerox as a family and I was amazed at
the number of people who have worked here for so long.’ It’s tempting to take
Moloney’s comments with a pinch of salt, especially considering that when you’ve
been working somewhere for only two years, as she has at Xerox, everyone seems
old and established. But there’s truth behind her enthusiasm.
Take Carole Palmer, the group resources director. She joined Xerox in 1978 as
a temp and has been in her present role for seven years. ‘Xerox has been good to
me over the years,’ she says. ‘It has supported me through qualifications … and
last year I took part in the vice-president incumbent program.’ Human resources
is taken seriously at Xerox, Palmer says, and the company has a policy of
promoting from within (which would explain Moloney’s amazement at her
colleagues’ longevity). The company takes on only fifteen to twenty graduates
each year and Moloney was part of an intake who joined having already acquired a
couple of years’ work experience. She started as a project manager for Xerox
Global Services before moving into sales. Now her responsibility is to ‘grow and
maintain customer relationships’.
Moloney is based at the head office in Uxbridge. ‘It’s great in terms of
working environment,’ she says. ‘We’ve just got a new provider in the canteen
and … we have brainstorming rooms and breakout areas.’ Much of Moloney’s role is
visiting clients, so she doesn’t have a permanent desk at head office. ‘I’m a
hot-desker, which is good because you get to sit with different people in the
hot-desk areas. And you’re given a place to store your things.’ Head office
staff numbers between 1,200 and 1,500 people, Palmer says. The company has four
other main offices in the UK. The nature of the organization, which encompasses
sales and marketing, global services (the biggest division), developing markets,
research and development and manufacturing, means that the opportunities at the
company vary from service engineers to sales roles and consultants.
Perks include a final-salary pension scheme and various discount schemes. The
reward and recognition scheme is a little different, and rather nice: ‘Each
manager has a budget every year to recognize and reward staff,’ Palmer says. ‘It
can be in the form of a meal for two, or a bottle of wine. It can be up to
£1,000. There’s the recognition, and then there’s putting money behind it.’
Moloney, however, likes the non-cash rewards. ‘Xerox takes care of all its staff
but it also recognizes the people who put in the added effort,’ she says. ‘It
offers once-in-a-lifetime incentive trips, and recently I organized a sailing
trip for my team.’
The idea of working abroad with the company appeals to her, and she says that
her career goal is to be part of the senior management team. Here’s another
employee, it would seem, who is in it for the long haul.

new weapon to fight cancer
1. British scientists are preparing to launch trials of a radical new way to
fight cancer, which kills tumours by infecting them with viruses like the common
cold.
2. If successful, virus therapy could eventually form a third pillar
alongside radiotherapy and chemotherapy in the standard arsenal against cancer,
while avoiding some of the debilitating side-effects.
3. Leonard Seymour, a professor of gene therapy at Oxford University, who has
been working on the virus therapy with colleagues in London and the US, will
lead the trials later this year. Cancer Research UK said yesterday that it was
excited by the potential of Prof Seymour’s pioneering techniques.
4. One of the country’s leading geneticists, Prof Seymour has been working
with viruses that kill cancer cells directly, while avoiding harm to healthy
tissue. "In principle, you’ve got something which could be many times more
effective than regular chemotherapy," he said.
5. Cancer-killing viruses exploit the fact that cancer cells suppress the
body’s local immune system. "If a cancer doesn’t do that, the immune system
wipes it out. If you can get a virus into a tumour, viruses find them a very
good place to be because there’s no immune system to stop them replicating. You
can regard it as the cancer’s Achilles’ heel."
6. Only a small amount of the virus needs to get to the cancer. "They
replicate, you get a million copies in each cell and the cell bursts and they
infect the tumour cells adjacent and repeat the process," said Prof Seymour.
7. Preliminary research on mice shows that the viruses work well on tumours
resistant to standard cancer drugs. "It’s an interesting possibility that they
may have an advantage in killing drug-resistant tumours, which could be quite
different to anything we’ve had before."
8. Researchers have known for some time that viruses can kill tumour cells
and some aspects of the work have already been published in scientific journals.
American scientists have previously injected viruses directly into tumours but
this technique will not work if the cancer is inaccessible or has spread
throughout the body.
9. Prof Seymour’s innovative solution is to mask the virus from the body’s
immune system, effectively allowing the viruses to do what chemotherapy drugs do
- spread through the blood and reach tumours wherever they are. The big hurdle
has always been to find a way to deliver viruses to tumours via the bloodstream
without the body’s immune system destroying them on the way.
10. "What we’ve done is make chemical modifications to the virus to put a
polymer coat around it - it’s a stealth virus when you inject it," he said.
11. After the stealth virus infects the tumour, it replicates, but the copies
do not have the chemical modifications. If they escape from the tumour, the
copies will be quickly recognised and mopped up by the body’s immune system.
12. The therapy would be especially useful for secondary cancers, called
metastases, which sometimes spread around the body after the first tumour
appears. "There’s an awful statistic of patients in the west ... with malignant
cancers; 75% of them go on to die from metastases," said Prof Seymour.
13. Two viruses are likely to be examined in the first clinical trials:
adenovirus, which normally causes a cold-like illness, and vaccinia, which
causes cowpox and is also used in the vaccine against smallpox. For safety
reasons, both will be disabled to make them less pathogenic in the trial, but
Prof Seymour said he eventually hopes to use natural viruses.
14. The first trials will use uncoated adenovirus and vaccinia and will be
delivered locally to liver tumours, in order to establish whether the treatment
is safe in humans and what dose of virus will be needed. Several more years of
trials will be needed, eventually also on the polymer-coated viruses, before the
therapy can be considered for use in the NHS. Though the approach will be
examined at first for cancers that do not respond to conventional treatments,
Prof Seymour hopes that one day it might be applied to all cancers.

1 There's a dimmer switch inside the sun that causes its brightness to rise
and fall on timescales of around 100,000 years - exactly the same period as
between ice ages on Earth. So says a physicist who has created a computer model
of our star's core.
2 Robert Ehrlich of George Mason University in Fairfax, Virginia, modelled
the effect of temperature fluctuations in the sun's interior. According to the
standard view, the temperature of the sun's core is held constant by the
opposing pressures of gravity and nuclear fusion. However, Ehrlich believed that
slight variations should be possible.
3 He took as his starting point the work of Attila Grandpierre of the Konkoly
Observatory of the Hungarian Academy of Sciences. In 2005, Grandpierre and a
collaborator, Gábor ágoston, calculated that magnetic fields in the sun's core
could produce small instabilities in the solar plasma. These instabilities would
induce localised oscillations in temperature.
4 Ehrlich's model shows that whilst most of these oscillations cancel each
other out, some reinforce one another and become long-lived temperature
variations. The favoured frequencies allow the sun's core temperature to
oscillate around its average temperature of 13.6 million kelvin in cycles
lasting either 100,000 or 41,000 years. Ehrlich says that random interactions
within the sun's magnetic field could flip the fluctuations from one cycle
length to the other.
5 These two timescales are instantly recognisable to anyone familiar with
Earth's ice ages: for the past million years, ice ages have occurred roughly
every 100,000 years. Before that, they occurred roughly every 41,000 years.
6 Most scientists believe that the ice ages are the result of subtle changes
in Earth's orbit, known as the Milankovitch cycles. One such cycle describes the
way Earth's orbit gradually changes shape from a circle to a slight ellipse and
back again roughly every 100,000 years. The theory says this alters the amount
of solar radiation that Earth receives, triggering the ice ages. However, a
persistent problem with this theory has been its inability to explain why the
ice ages changed frequency a million years ago.
7 "In Milankovitch, there is certainly no good idea why the frequency should
change from one to another," says Neil Edwards, a climatologist at the Open
University in Milton Keynes, UK. Nor is the transition problem the only one the
Milankovitch theory faces. Ehrlich and other critics claim that the temperature
variations caused by Milankovitch cycles are simply not big enough to drive ice
ages.
8 However, Edwards believes the small changes in solar heating produced by
Milankovitch cycles are then amplified by feedback mechanisms on Earth. For
example, if sea ice begins to form because of a slight cooling, carbon dioxide
that would otherwise have found its way into the atmosphere as part of the
carbon cycle is locked into the ice. That weakens the greenhouse effect and
Earth grows even colder.
9 According to Edwards, there is no lack of such mechanisms. "If you add
their effects together, there is more than enough feedback to make Milankovitch
work," he says. "The problem now is identifying which mechanisms are at work."
This is why scientists like Edwards are not yet ready to give up on the current
theory. "Milankovitch cycles give us ice ages roughly when we observe them to
happen. We can calculate where we are in the cycle and compare it with
observation," he says. "I can't see any way of testing [Ehrlich's] idea to see
where we are in the temperature oscillation."
10 Ehrlich concedes this. "If there is a way to test this theory on the sun,
I can't think of one that is practical," he says. That's because variation over
41,000 to 100,000 years is too gradual to be observed. However, there may be a
way to test it in other stars: red dwarfs. Their cores are much smaller than
that of the sun, and so Ehrlich believes that the oscillation periods could be
short enough to be observed. He has yet to calculate the precise period or the
extent of variation in brightness to be expected.
11 Nigel Weiss, a solar physicist at the University of Cambridge, is far from
convinced. He describes Ehrlich's claims as "utterly implausible". Ehrlich
counters that Weiss's opinion is based on the standard solar model, which fails
to take into account the magnetic instabilities that cause the temperature
fluctuations.

What does the future hold for the problem of housing? A good deal depends, of
course, on the meaning of “future”. If one is thinking in terms of science
fiction and the space age, it is at least possible to assume that man will have
solved such trivial and earthly problems as housing. Writers of science fiction,
from H.G. Wells onwards, have had little to say on the subject. They have
conveyed the suggestion that men will live in great comfort, with every
conceivable apparatus to make life smooth, healthy and easy, if not happy. But
they have not said what his house will be made of. Perhaps some new building
material, as yet unimagined, will have been discovered or invented at least. One
may be certain that bricks and mortar(泥灰，灰浆) will long have gone out of
fashion.
But the problems of the next generation or two can more readily be imagined.
Scientists have already pointed out that unless something is done either to
restrict the world’s rapid growth in population or to discover and develop new
sources of food (or both), millions of people will be dying of starvation or at
the best suffering from underfeeding before this century is out. But nobody has
yet worked out any plan for housing these growing populations. Admittedly the
worst situations will occur in the hottest parts of the world, where housing can
be light structure or in backward areas where standards are traditionally low.
But even the minimum shelter requires materials of some kind and in the teeming,
bulging towns the low-standard “housing” of flattened petrol cans and dirty
canvas is far more wasteful of ground space than can be tolerated.
Since the war, Hong Kong has suffered the kind of crisis which is likely to
arise in many other places during the next generation. Literally millions of
refugees arrived to swell the already growing population and emergency steps had
to be taken rapidly to prevent squalor(肮脏)and disease and the spread crime. The
city is tackling the situation energetically and enormous blocks of
tenements(贫民住宅)are rising at an astonishing aped. But Hong Kong is only one
small part of what will certainly become a vast problem and not merely a housing
problem, because when population grows at this rate there are accompanying
problems of education, transport, hospital services, drainage, water supply and
so on. Not every area may give the same resources as Hong Kong to draw upon and
the search for quicker and cheaper methods of construction must never cease.
