`A Reporter's Paper': The National Thrift News, Journalistic Autonomy and the Savings and Loan Crisis

Business journalism comes under persistent criticism for serving its historic readership of brokers and business people while lacking sufficient autonomy and failing to sufficiently question or challenge powerful corporate and economic interests. This is a dominant theme in media criticism of the savings and loan crisis⁠ and 2008 financial crisis.⁠ Against this backdrop, this dissertation asks: Is this critique valid, and if so, how can business journalism improve? To engage these questions, this dissertation examines the question of autonomy in business journalism in an unlikely place: the trade press. The central case study is coverage of the savings and loan crisis by the National Thrift News, a small financial services newspaper that won a George Polk award for its reporting in 1988. How could a small trade newspaper succeed in some instances when larger news organizations failed to connect the dots? The National Thrift News created a newsroom environment that celebrated reporter autonomy and independence. In some cases, it used its insider knowledge and consistent beat reporting to serve both its core readers and the broader society by uncovering savings and loan corruption. This study will highlight a long-running debate among theorists of journalistic professionalism by arguing that the commercial and advertising model in journalism does not inevitably compromise journalistic independence⁠ but rather can help pave a way forward for a more independent press. It therefore challenges the political economy critique of journalism, which holds that external forces such as capitalism harm press independence. This case suggests journalistic independence and individual agency remain powerful forces in newsrooms. Lastly, the dissertation argues that in an era of media downsizing, the trade press can perform an even more useful watchdog role over industry if the mainstream news media acknowledges and pursues some of the innovative trade reporting.

Independent television production, TV formats and media diversity in China

Beginning around 2003, television studies has seen the growth of interest in the genre of reality shows. However, concentrating on this genre has tended to sideline the even more significant emergence of the program format as a central mode of business and culture in the new television landscape. "Localizing Global TV" redresses this balance, and heralds the emergence of an important, exciting and challenging area of television studies. Topics explored include reality TV, makeover programs, sitcoms, talent shows and fiction serials, as well as broadcaster management policies, production decision chains and audience participation processes. This seminal work will be of considerable interest to media scholars internationally.

Tinamous and moa flock together : mitochondrial genome sequence analysis reveals independent losses of flight among ratites

Ratites are large, flightless birds and include the ostrich, rheas, kiwi, emu, and cassowaries, along with extinct members, such as moa and elephant birds. Previous phylogenetic analyses of complete mitochondrial genome sequences have reinforced the traditional belief that ratites are monophyletic and tinamous are their sister group. However, in these studies ratite monophyly was enforced in the analyses that modeled rate heterogeneity among variable sites. Relaxing this topological constraint results in strong support for the tinamous (which fly) nesting within ratites. Furthermore, upon reducing base compositional bias and partitioning models of sequence evolution among protein codon positions and RNA structures, the tinamou–moa clade grouped with kiwi, emu, and cassowaries to the exclusion of the successively more divergent rheas and ostrich. These relationships are consistent with recent results from a large nuclear data set, whereas our strongly supported finding of a tinamou–moa grouping further resolves palaeognath phylogeny. We infer flight to have been lost among ratites multiple times in temporally close association with the Cretaceous–Tertiary extinction event. This circumvents requirements for transient microcontinents and island chains to explain discordance between ratite phylogeny and patterns of continental breakup. Ostriches may have dispersed to Africa from Eurasia, putting in question the status of ratites as an iconic Gondwanan relict taxon.

Independent, marked associations of alleles of the insulin receptor and dipeptidyl carboxypeptidase-I genes with essential hypertension

1. There is evidence to suggest that essential hypertension is a polygenic disorder and that it arises from yet-to-be-identified predisposing variants of certain genes that influence blood pressure. The cloning of various hormone, enzyme, adrenoceptor and hormone receptor genes whose products are involved in blood pressure control and the identification of polymorphisms of these has permitted us to test their genetic association with hypertension. 2. Cross-sectional analyses of a number of candidate gene markers were performed in hypertensive and normotensive subjects who were selected on the basis of both parents being either hypertensive or normotensive, respectively, and the difference in total alleles on all chromosomes for each polymorphism between the hypertensive and normotensive groups was test by χ analysis with one degree of freedom. 3. A marked association was observed between hypertension and insertion alleles of polymorphisms of the insulin receptor gene (INSR) (P<0.0040) and the dipeptidyl carboxypeptidase-1 (angiotensin I-converting enzyme; kininase II) gene (DCP1) (P<0.0018). No association with hypertension was evident, however, for polymorphisms of the growth hormone, low-density lipoprotein receptor, renal kallikrein, α2- and β1-adrenoreceptor, atrial natriuretic factor and insulin genes. 4. All but one of the hypertensive subjects had at least one of the hypertension-associated alleles, and although subjects homozygous for both were three times more frequent in the hypertensive group, examination of the nine possible genotypes suggested that the INSR and DCP1 alleles are independent markers for hypertension. 5. The present results suggest that genetic variant(s) in close linkage disequilibrium with polymorphisms at INSR and DCP1 may be involved in part in the aetiology of essential hypertension.

From Aussiewood Movies to Guerrilla Filmmaking: Independent Filmmaking and Contemporary Australian Cinema

Independent filmmaking within the context of Australian cinema is a multifaceted subject. In comparison to the United States, where production can be characterised as bifurcated between major studio production and so-called “indie” or independent production without the backing of the majors, since the 1970s and until recently the vast majority of Australian feature film production has been independent filmmaking. Like most so-called national cinemas, most Australian movies are supported by both direct and indirect public subvention administered by state and federal government funding bodies, and it could be argued that filmmakers are, to a certain degree, “dependent” on official mandates. As this chapter demonstrates national production slates are subjected to budget restraints and cut-backs, official cultural policies (for example pursuing international co-productions and local content quotas) and shifts in policy directions among others. Therefore, within the context of Australian cinema, feature film production operating outside the public funding system could be understood as “independent”. However, as is the case for most English-language national cinemas, independence has long been defined in terms of autonomy from Hollywood, and – as alluded to above – as Australia becomes more dependent upon international inputs into production, higher budget movies are becoming less independent from Hollywood. As such, this chapter argues that independence in Australian cinema can be viewed as having two poles: independence from direct government funding and independence from Hollywood studios. With a specific focus on industry and policy contexts, this chapter explores key issues that constitute independence for Australian cinema. In so doing it examines the production characteristics of four primary domains of contemporary independent filmmaking in Australia, namely: “Aussiewood” production; government-backed low-to-mid budget production; co-productions; and guerrilla filmmaking.

Phospholipid composition of the rat lens is independent of diet

Dietary fatty acids are known to influence the phospholipid composition of many tissues in the body, with lipid turnover occurring rapidly. The aim of this study was to investigate whether changes in the fatty acid composition of the diet can affect the phospholipid composition of the lens. Male Sprague-Dawley rats were fed three diets with distinct profiles in both essential and non-essential fatty acids. After 8 weeks, lenses and skeletal muscle were removed, and the lenses sectioned into nuclear and cortical regions. In these experiments, the lens cortex was synthesised during the course of the variable lipid diet. Phospholipids were then identified by electrospray ionisation tandem mass spectrometry, and quantified via the use of internal standards. The phospholipid compositions of the nuclear and cortical regions of the lens differed slightly between the two regions, but comparison of the equivalent regions across the diet groups showed remarkable similarity. In contrast, the phospholipid composition of skeletal muscle (medial gastrocnemius) in these rats varied significantly. This study provides the first direct evidence to show that the phospholipid composition of the lens is tightly regulated and thus appears to be independent of diet. As phospholipids determine membrane fluidity and influence the activity and function of integral membrane proteins, regulation of their composition may be important for the function of the lens.

Association of MMP-2 activation potential with metastatic progression in human breast cancer cell lines independent of MMP-2 production

Background: Expression of matrix metalloproteinase-2 (MMP-2), the 72-kd type IV collagenase/gelatinase, by cancer cells has been implicated in metastasis through cancer cell invasion of basement membranes mediated by degradation of collagen IV. However, the abundance of this latent proenzyme in normal tissues and fluids suggests that MMP-2 proenzyme utilization is limited by its physiological activation rather than expression alone. We previously reported activation of this proenzyme by normal and malignant fibroblastoid cells cultured on collagen I (vitrogen) gels. Purpose: Our purposes in this study were 1) to determine whether MMP-2 activation is restricted to the more invasive human breast cancer cell lines and 2) to localize the activating mechanism. Methods: Zymography was used to monitor MMP-2 activation through detection of latent MMP-2 (72 kd) and mature species of smaller molecular weight (59 or 62 kd). Human breast cancer cell lines cultured on plastic, vitrogen, and other matrices were thus screened for MMP- 2 activation. Collagen I-cultured cells were exposed to cycloheximide, a protein synthesis inhibitor, or to protease inhibitors to determine the nature of the MMP-2-activating mechanism. Triton X-114 (TX-114) detergent extracts from cells cultured on collagen I or plastic were incubated with latent MMP-2 and analyzed by zymography to localize the MMP-2 activator. Results: MMP-2 activation was only induced by collagen I culture in the more aggressive, highly invasive estrogen receptor-negative, vimentin-positive human breast cancer cell lines (Hs578T, MDA-MB-436, BT549, MDA-MB-231, MDA- MB-435, MCF-7(ADR)) and was independent of MMP-2 production. MMP-2 activation was detected in cells cultured on collagen I gels but not in those cultured on gelatin gels, Matrigel, or thin layers of collagen I or IV, gelatin, or fibronectin. Collagen-induced activation was specific for the enzyme species MMP-2, since MMP-9, the 92-kd type IV collagenase/gelatinase, was not activatable under similar conditions. MMP-2 activation was inhibited by cycloheximide and was sensitive to a metalloproteinase inhibitor but not to aspartyl, serine, or cysteinyl protease inhibitors. MMP-2 activation was detected in the hydrophobic, plasma membrane-enriched, TX-114 extracts from invasive collagen I-cultured cells. Conclusion: Collagen I-induced MMP-2 activation is restricted to highly invasive estrogen receptor-negative, vimentin-positive human breast cancer cell lines, is independent of MMP-2 production, and is associated with metastatic potential. Our findings are consistent with plasma membrane localization of the activator. Implications: The MMP-2 activation mechanism may represent a new target for diagnosis, prognosis, and treatment of human breast cancer.
