Catholic Reiki
Is it just me or is the notion of the Catholic Church accusing Reiki practitioners of having beliefs that "lack scientific credibility" seem ironic? I am in favour of the Church promoting belief in science and even for it to accuse Reiki practitioners of science, but I must admit that a frisson of irony bubbles through me at the thought.
Of course, reiki is 'superstition' and is in no way similar to Catholic beliefs like saints laying on of hands. Of course.

Poor Blacks 'Envy' Rich Whites
Here I report briefly on a recent paper in the Cambridge Journal of Economics by Haile, Sadrieh and Verbon. I appreciate the intentions of the paper, but I believe that it was poorly executed and, consequently, their results are unconvincing. As the authors state, "[N]o study so far has attempted to disentangle the ethnicity effects from the income inequality effects." (705) Their study fails to disentangle the effects too.
The authors ran trust games in two South African universities: The Universities of Potchefstroom and Mafikeng. (Clarification: They are now both campuses of North-West University.) They say the University of Potchefstroom is predominantly White, it is not. In 2003 the university had 41% White students, and the majority of students were Black (47%) with the remainder Coloured, Asian and Other (report here). For Mafikeng the statistics in 2003 were 0.5% White and 98.5% Black with the remainder Coloured and Asian (report here).
The authors ran anonymous control experiments in which no information was revealed. In the treatment experiment both race and income level were revealed. They revealed race and income by telling subjects directly whether their partner had reported themselves as White or Black, and also whether their partner had reported their perceived income as above average or below average. There are thus four potential categories: {Black-Low, Black-High, White-Low, White-High}.
The first problem is with their racial categorization. In South Africa people report whether they are White, African, Coloured, or Asian with the three final groups all counting as 'Black' (see the CEE report here). The authors assumed that all subjects would know what was meant by 'Black'. I did not see evidence that they tested this. Moreover, as shown by Tyson et al (1988), the levels of prejudice within Whites varies dramatically with significantly lower levels of prejudice (towards non-whites) among English home language Whites than among Afrikaans home language Whites. Furthermore, when the researchers provided the racial information in this way it erased any possibility to understand the underlying mechanisms to identify ingroup and outgroup membership. Why not use names (Bertrand and Mullainathan 2004, Van der Merwe and Burns 2008)? photographs (Eckel and Wilson 2002, Burns 2004, 2006)? cartoons (can't remember the reference)?
Second, their experimental design was poor. To separate the effects of race and income, and to postulate about combined effects we need experiments on each of these separately. What this means is that they ran an insufficient number of treatments. We not only need race treatments alone, but also income treatments alone for a full complement of treatments that would allow valid interpretations of their results, i.e., we need {(black, white) (white, black), (black, black) (white, white)} treatments, and {(high, low) (high, high), (low, low), (low, high)} treatments. Once these have been run then you can do Haile, Sadrieh and Verbon's experiment. Their experiment does not actually isolate what they say it does.
Third, saying that low income Blacks don't give to high income Whites is because of 'envy' may be inaccurate. Though the behaviour is exhibited for low income blacks towards high income whites only they may feel resentment, spite, or hatred towards this group for reasons correlated with high income and whiteness (say, family complicity with apartheid, perceptions of persistent racism, political inclinations, undeserved benefits - on average Whites more likely to be employed and have higher income in North-West than Blacks). Black people in Potchefstroom, for example, may hate the (predominantly Afrikaans?) richer Whites. I understand that saying hatred motivates people is not politically correct, but saying that the Haile, Sadrieh and Verbon result is a consequence of envy without admitting other possibilities is speculation. What about disgust? spite? anger?
Fourth, why do they not present any independent evidence from the sampled students, or perceptions by other students at the universities, on socio-economic data about black, white, high income and low income individuals? If we had more information about these factors then we might have greater insight into the factors underlying the 'envy' result.
Lastly, the sample does not contain a sufficient number of wealthy Blacks. I believe this to be a consequence of where the authors chose to run the experiments. Had they chosen to run the experiments in Cape Town, Johannesburg or Pretoria they would probably have found more (though not many) wealthier Blacks. Instead, they chose areas that were particularly unsuited to their needs. North-West is one of the poorer South African provinces (see basic provincial information).
There are several other points worthy clarifying, but the points I raise were those that came to mind. I hope that more and similar work is carried out in South Africa, particularly work that "[attempts] to disentangle ethnicity effects from income inequality effects." With this work as a baseline I think that a substantial amount of research can proceed and clarify the results that Haile, Sadrieh and Verbon present.
Point of clarity
I have tried twice to contact Prof Verbon as the contact author listed on the paper to obtain additional information not listed in the paper. I have not received any responses.

Fiction
Graham Greene - The Quiet American
As The Quiet American was the first Greene novel that I read, I had to accustom myself to Greene's style - it's clean and can stab you suddenly with a particularly deft or accurate description. I thought his characterization was precise: Phuong and her Princess Anne, Fowler's responses to his wife, Pyle's naiveté. Greene's voice is well-directed, displaying his contempt for polar morality, and specifically the jingoistic, with-us-or-against-us thinking of 20th century USA.
The plot unfolds inevitably - the inertia of Pyle's beliefs about the US and Indochina propel the narrative onwards. Greene depicts a game of political chicken. In the ultimate moments, neither driver has the insight to spin their steering wheel to avoid collision. The end must be violent. Greene was known to dislike US foreign policy, and to portray the world as a palette of moral greys - The Quiet American captures both sensibilities well.
Ian McEwan - On Chesil Beach
On Chesil Beach is the first Ian McEwan book I've read. In it he describes a newly married couple's relationship and their struggle to culminate their wedding vows. McEwan maps their relationship up to their marriage: how
their intimacy evolved, how they came to love each other, how personal taboos result in their inevitable repulsion.
McEwan's prose is direct: it cuts you, sews you back up, then slices the sutures to expose the wound. Occasionally though his attempts to re-slice don't succeed and you get the sense that a medical intern is fumbling with your wound, rather than having a doctor perform exact surgery.
I am thankful the book is short. I think it could have been shorter. McEwen, though developing the characters a bit, does not develop Flo and Ed as fully as I would have expected from a novel. If he intended to write spare prose, to be cutting, then this book could have been a lengthy short story in a collection, rather than a short novel. That said, I still enjoyed it and don't lament having read it as some reviewers did.
Useless information: the book's front cover annoyed me. A red information circle told me that the book was written by 'The Bestselling Author of Atonement'. As much as I appreciate this information, I detest images on the covers of books that are not to do with the book itself. I always remove all price tags and stickers from books and I scratched at this circle many times wishing I could erase it.
Non-fiction
On writing: I have recently read several books on writing. All of the books were useful as each filled a gap the others did not.
Clare Kehrwald Cook, 1985, Line By Line: How to edit your own writing Cook's advice on editing is separated into five sections: Loose, Baggy Sentences; Faulty Connections; Ill-matched Partners; Mismanaged Numbers and References; and Problems with Punctuation.
Cook advises that you revise repeatedly. She argues that no one is better than the author at understanding the meaning that they intend, and that they can best select the appropriate verb, and delete the unnecessary adverbs, prepositions and other fluff. Her method includes instructions on tracing subjects and verbs, clearing out lurking prepositional phrases, and more. We understands her method because Cook provides many examples and many solutions, while reminding us to propose our own solutions for practice.
The book contains two appendixes: the first reviews the parts of sentences, the second is a glossary of 'questionable usage'. The appendix on grammar is particularly useful because you can refer to it if you come across an odd or forgotten term that you need to clarify.
I found the book useful and instructive. It complements other grammar and style texts well. I plan to re-read it to incorporate the rules into my writing and my editing.
Booth, Colomb and Williams, 2008, The Craft of Research, 3rd Edition.
Booth, Colomb and Williams's book is probably best read by an undergraduate, an inexperienced graduate student, or a junior professional. Nevertheless, I found it useful because my research education was predominantly experiential: an osmosis of 'do this' and 'don't do that' from mentors and supervisors. This book fills in the gaps. The authors instruct us in all the phases of research from the initial stages through to drafting and reviewing. I appreciated the framework as I have never done a formal research course. (Odd for a graduate student I think - it seems economists believe in research 'tools' other than writing and drafting.)
The book has four main sections. Booth, Colomb and Williams introduce by asking What is research? and Why write it up? They proceed to the initial steps of research: research questions, research problems and the nuances of sources. Third, they consider the basics of argumentation: claims, reasons and the problematic notion of 'warrants'. Fourth, they discuss drafting, revision, visual evidence, introductions and conclusions, and style. They provide useful examples and concrete advice; the 'Quick Tips' at the end of each chapter are
very good and I will probably quote them to students one day. They write with a humorous and avuncular tone - like someone giving you kindly advice rather than chastising you from on high.
I plan to re-read the book to reinforce the need to discipline myself, to obey rules I should, and to adopt methods superior to my half-evolved ones. As the authors comment, the book should be accompanied by other guides on style, grammar and editing. I would recommend Strunk and White's The Elements of Style and Cook's Line by Line. For social scientists, McCloskey's Economical Writing serves well. For other non-fiction writers William Zinsser's On Writing Well (comment below).
William Zinsser - On Writing Well
Zinsser's book, first published in the 70s, is part how-to, part autobiography and part travelogue. I say travelogue because he writes by telling us about the landmarks in 'good writing', the individuals who populate it and the methods that we should adopt to understand and better relate to good writing. His book verges on ethnography.
Echoing messages from Strunk & White; Booth, Colomb & Williams; McCloskey; Cook and several others, Zinsser endorses a writing style derived from accurate verbs and precise nouns. I believe this is the best advice he could give and he provides many motivations for his claims about style.
One Amazon reviewer felt let-down by Zinsser's continuous referral to his own writing processes, the reviewer wanted something even more 'how-to'. I found this criticism odd. Zinsser describes a method to write, contextualised in his work. He repeats a writer needs to write and edit, write and edit. He describes several ways to do this. He instructs the reader on methods for given subject matter and applies his methods by conjuring examples from his extensive knowledge of good writing, as well as his acquaintance with poor writing. Additionally, I have not read any writing guide that was 'independent' of its author, in fact if such a guide were written it would probably be hollow and vapid. Read the book and enjoy Zinsser's insight into writing well. I treasure this book already and I shall probably refer to it many times in the future.
On other topics
Ryszard Kapuscinski - The Shadow of the Sun
This book is fantastic. Kapuscinski's essays on his experiences of living in, toiling through, and growing to adore Africa are phenomenal. I intend to put essays from this book on my reading lists for students when I teach courses about African Development one day.
When he writes, Kapuscinski captures what economists take reams to deliver. African development remains dependent on aid in many countries, many societies lack basic resources, and institutions built for extraction and exploitation obstruct their development.
Kapuscinski laments Africa's poor development and wishes that something could have happened to put more of African countries on paths to development. Kapuscinski's writing pulls you into the deep sadness he feels when he reflects on Africa, but the root of that sadness is a strong, powerful love that will draw him back to the continent, and, I hope, one day make him happy about the continent's achievements.
Anne Fadiman - At Large and At Small: Confessions of a Literary Hedonist
Prior to reading Fadiman's Ex Libris: Confessions of a Common Reader, I had not delved much into the personal essay genre. Reading Fadiman has changed that. My wife bought me Ex Libris for our first anniversary, subsequent to which and a couple of weeks after returning home, I looked up Fadiman online to see that At Large and At Small had recently been published. It is most definitely a 'literary gem', as one of the Amazon reviewers comments.
Fadiman deals with sensitive topics gracefully and wittily. In an interview, Fadiman commented that writing personal essays requires that you turn up the 'loudness of your voice'. If so, then somehow Fadiman has managed to select the perfect decibel equivalent at which her writings retain intimacy and factualness while they sustain humour and poignancy. Fadiman shows how she, and anyone really, can be simultaneously enamoured of an historic figure, while perturbed by their character, as evidenced by her commentary on Coleridge and Stefansson. Such personal paradoxes tie well into her essay on the culture wars where she laments the polarization of what makes literature worthwhile. She concludes that both literary value and moral lessons engage the reader and promote literature of all kinds and that the dichotomy is false. These and other ideas float tantalizingly on the surfaces of her essays, while anchored suitably by her research and by her breadth of reading.
I strongly recommend this book to anyone interested in Fadiman's previous collection Ex Libris, while telling them to be aware that they are in for a different literary journey: equally as good, but with a more varied landscape of subject matter.
Lewis Buzbee - The Yellow-Lighted Bookshop
Having read Ex Libris and At Large and At Small
(above) I rated them on amazon.co.uk. This book appeared on my 'recommendations' list soon afterward. It was relatively inexpensive and well-reviewed, so I took the risk. I was very happy that I did so.
Buzbee's memoir and history detail his experience of book-selling in addition to describing the dynamics of selling books in the past, from Alexandrian scroll-sellers to modern day door-to-door Bible and encyclopedia salesmen (they seem always to be men, don't they?).
The book is easy to read, informative and well-written. It fills a space in my burgeoning collection of books about books. It is worth reading simply for the anecdotes that Buzbee recounts about the book industry. The research he put in to the history of books, book selling and publishing makes the book even more entertaining. I was happy Amazon's algorithms selected this book for me.
Next time
I am currently reading E.B. White's Essays of E.B.White, Paul Johnson's Creators and Marc Hauser's Moral Minds. I'll let you know how they go.

South African Scores an Own Goal for Democracy
Wow! Denying the Dalai Lama a visa, that's what I call self-righteous.
Or maybe it suppresses speech, shows South Africa kowtowing to Chinese interests and promotes illiberal politics inconsistent with the South African constitution.
I could be wrong though. it could be 'an independent, sovereign decision' as Ronnie Mamoepa says.
Hmm... methinks kitty represents my opinion well.
Anyway, this highlights the value of blogging. People make a point, others, in the know and with access to the statistics, correct them quickly. Consequently, our intellectual capital can develop swiftly and improve in accuracy. What a valuable process!
