This study seeks to determine which attributes of a film affect a measure of its rate of return when using data for both foreign and domestic box office sales. The data from a previous study by Brewer, Kelley and Jozefowicz is used, with the dependent variable adjusted to rate of return and revenue is adjusted to include foreign sales. A regression analysis is performed in order to determine the significant factors for this dependent variable. It is found that, contrary to studies using revenue as the dependent variable, budget has a negative effect on a film's rate of return. Along with this, star power is relatively meaningless, while critical review, film nominations and word of mouth appeal are each quite significant. The implications of this study suggest that Hollywood can increase its profitability by diversifying its portfolio to include a number of smaller budgeted projects as opposed to a select few blockbusters.
Agriculture, like many primary and service sectors, is a frequent recipient of innovation intended for its use, even if those innovations originate in industrial sectors. The challenge has been identifying them from patent data, which are recorded for administrative purposes using the International Patent Classification (IPC) system. We reprogram a well-tested tool, the OECD Technology Concordance (OTC), to identify 16 million patents granted between 1975 and 2006 worldwide which have potential application in agriculture. This paper presents the methodology of that dataset’s construction, introduces the data via summaries by nation and industrial sector over time, and suggests some potential avenues for future exploration of empirical issues using these data.
Described by Western Minerals Inc. as 'porphyroblastic metasediments/hybrid rocks, interpreted by Eales and his coworkers as metamorphosed 'Red Beds' Formation sediments but conceivably magmatic in origin. The specimens illustrate the range in textures and compositions.' A common characteristic of all minerals in this thin section is that despite their natural habit, most minerals are elongate and frequently form cross-cutting, disparate but optically continuous, bladed crystals. It appears to be an almost dendritic intergrowth of all phases.
The dominant texture in this gabbro is an ophitic intergrowth of equant plagioclase laths within larger, subhedral, clinopyroxene grains. Alteration of some phases to chlorite, talc and clays is localized and occurs more in non-ophitic sections of the rock.
Phenocrystic phases in this thin section are subhedral plagioclase, clinopyroxene, and orthopyroxene, found both as isolated crystals and as glomeroporphyroclasts. Some plagioclase phenocrysts have inclusions of equant pyroxenes and blebs of glass. Glass and plagioclase comprise the vesicular groundmass.
The groundmass of this porphyritic basalt is predominantly glass with less abundant plagioclase microlites. The most readily-identifiable mineral of the phenocryst population is plagioclase. Of greater abundance are euhedral, opaque pseudomorphs. Rare inclusions of pyroxene are observed within these opaques. Pockets of chalcedony disrupt the otherwise uniform groundmass.
This thin section has a diabasic texture. While the plagioclase has remained relatively unaltered, clinopyroxene has been almost entirely pseudomorphed by serpentine. Anhedral clusters of calcite is found throughout.
Phenocrysts of plagioclase, clinopyroxene, and iddingsite pseudomorphs after olivine–presumably–are surrounded by a groundmass of unoriented plagioclase microlites, glass, and localized calcite. Plucking of the phenocrysts is noticable and vesicles are present.
The plagioclase crystals in this vesicular basalt display a continuous range of sized from groundmass microlite to sieve-textured, sometimes zoned blocky phenocrysts. The groundmass contains more blocky plagioclase than other lavas from the Bali suite. The pyroxenes are generally subhedral and form glomeroporphyroclasts.
The least altered phase in this thin section is plagioclase, which forms roughly aligned, variably sized laths that make up both the groundmass, which is dominantly glass, and the phenocryst population. A second phenocryst, clinopyroxene, remains only as inclusions in the calcite pseudomorphs that replaced it. Vesicles, clays, and hematite pseudomorphs are abundant in this thin section.
Allotriomorphic omphacite and clinozoisite are intergrown with one another, with clinozoisite occurring frequently as inclusions within the omphacite crystals. The occurrence of muscovite is typically contained to polycrystalline nodes with radiating crystals. The conspicuous rutile grain in the center with radiating veinlets has a rim of plagioclase buffering it from the surrounding material. It contains inclusions of chlorite and sphene. Sphene is abundant as large, subhedral clasts.
This crenulated foliation is defined by elongate omphacite interleaved with clinozoisite, sphene, chlorite, muscovite, and the rarer glaucophane crystals. Euhedral though fractured garnets contain chlorite, muscovite, and omphacite inclusions. Hexagonal porphyroclasts of randomly-oriented chlorite are scattered throughout.
Subhedral phenocrysts of plagioclase, clinopyroxene, and olivine are squeezed into the fine web of rock that rims the massive vesicles of this scoria. Plagioclase has a sieve texture and is frequently zoned. The corners of most grains are rounded. Both clinopyroxene and olivine are generally equant in shape and olivine is more abundant than the pyroxene. All three phases show some degree of resorption. The groundmass contains moderately-sized crystals of all three phases. This sample is very fresh and unaltered.
The fabric in this thin section is more disordered than others from this suite. All phases commingle and an alignment of elongate phases amidst many equant phase forms a weak foliation. Garnet and omphacite form porphryclastic, poikiloblastic grains.
Glaucophane, muscovite, sphene, and elongate aggregates of epidote-group minerals define the foliation in this thin section. Poikiloblastic garnet and omphacite grains contain inclusions which include glaucophane and rutile.

Strongly aligned, microcrenulated glaucophane is the primary constituent of this blueschist. Sphene and muscovite are much less abundant.
This paragonite schist is peppered with euhedral and aggregated clinozoisite. A few phengitic pods with large zoisite grains are found.
