This study is an empirical and theoretical contribution to the burgeoning literature on gender and competitive boxing. By using Connell's concepts of labor, power, cathexis, and representation and a combination of content and semiotic analysis, interviews, and observations, we argue that competitive boxing can be studied productively as a paradoxical gender regime that simultaneously enables and constrains how women do gender. On one hand, the sport encourages individual women to display physical aggression when such behavior traditionally has been deemed the antithesis of femininity. Some feminists argue that this form of physical feminism enables women to transcend essentialist discourses that restrict their corporeal power. On the other hand, women boxers in general also encounter resistance to their aspirations. For example, they are still positioned by essentialist discourses about both their bodies and capacity to develop the requisite form of controlled aggression. Strongly gendered links between bodily labor and bodily capital also mean that women have less access to resources than do men and, consequently, fewer opportunities to develop their pugilistic capital. We also maintain that competitive women boxers are implicated in a body project that tends to replicate sporting practices that some feminists and pro-feminists argue are damaging to both men and women.

Lihavuus ja ylipaino ovat viime vuosikymmeninä yleistyneet; jo yli puolet länsimaiden väestöstä on ylipainoisia ja viidennes lihavia. Varsinkin nuorilla ylipainon lisääntyminen on ollut nopeaa. Ylipaino, erityisesti yhdistettynä vyötärölihavuuteen, sekä tupakointi lisäävät sairastavuutta sydän- ja verisuonisairauksiin, metabolisiin sairauksiin, kuten diabetekseen, sekä moniin syöpiin. Lihavuus ja tupakointi ovatkin kehittyneiden maiden tärkeimpiä ehkäistävissä olevia kuolinsyitä. Samanaikaisesti ylipainon kanssa laihduttaminen ja jopa terveydelle haitalliset laihdutusmenetelmät, kuten tupakointi painonhallintakeinona on tullut yhä yleisemmäksi. Nopeaan painonpudotukseen tähtäävällä laihduttamisella on usein terveydelle haitallisia seurauksia kuten painon nousu yli alkuperäisen painon ja kehon rasvajakauman muuttuminen epäterveellisemmäksi. Kolme neljännestä merkittävästi laihduttaneista kertoo painon nousseen takaisin. Tupakoinnin ja toistuvan laihduttamisen vaikutukset ylipainon ja lihavuuden kehittymiselle kytkeytyvät toisiinsa. Tässä väitöskirjatyössä tutkittiin toistuvan laihduttamisen ja tupakoinnin vaikutusta kehon painoon ja lisäksi tupakoinnin vaikutusta vyötärölihavuuden kehittymiseen. Työn toisena tavoitteena oli tutkia, kuinka voimakkaasti tupakointi ja toistuva laihduttaminen liittyvät toisiinsa suomalaisilla ja onko tämä yhteys erilainen eri ikäryhmissä ja sukupuolilla. Työ perustuu kolmeen laajaan kyselyaineistoon: Nuorten Kaksosten Terveystutkimuksen (englanniksi FinnTwin16) aineistossa on seurattu 1975-79 syntyneitä kaksosia 16, 17, 18 ja 24 vuoden ikäisinä (N=5563). Suomen kaksoskohortin aineisto (N= 12 793) on kerätty vuonna 1990 samaa sukupuolta olevilta, vuosina 1930-57 syntyneiltä kaksosilta. Entisten huippu-urheilijoiden (N=1838) ja heille kaltaistettujen verrokkien (N=834) seurantatutkimuksessa tiedot on kerätty vuosina 1985, 1995 ja 2001. Pituus, paino ja tupakointi on kysytty kaikissa kyselyissä. Kaksoset vastasivat laihdutuskäyttäytymistä koskeviin kysymyksiin. Urheilijoiden laihdutuskäyttäytyminen pääteltiin lajin perusteella, sillä toistuvan laihduttamisen tiedetään olevan yleistä painoluokissa urheilevilla urheilijoilla (esim.painijat, nyrkkeilijät). Nuoruusiän tupakointi ennusti vyötärölihavuutta molemmilla sukupuolilla ja lisäksi ylipainoisuutta naisilla. Toistuva laihduttaminen oli yhteydessä myöhempään painonnousuun ja lihavuuteen miehillä. Lisäksi toistuvan laihduttamisen ja tupakoinnin todettiin liittyvän toisiinsa nuorilla aikuisilla. Vanhemmissa ikäluokissa miehet, jotka tupakoivat, laihduttivat harvemmin kuin tupakoimattomat. Lihavuuteen ja vyötärölihavuuteen liittyvän oheissairastavuuden ennaltaehkäisyssä tupakoinnin ja toistuvan laihduttamisen vähentäminen saattavat olla aiemmin luultua tehokkaampia keinoja.

We describe a novel method for human activity segmentation and interpretation in surveillance applications based on Gabor filter-bank features. A complex human activity is modeled as a sequence of elementary human actions like walking, running, jogging, boxing, hand-waving etc. Since human silhouette can be modeled by a set of rectangles, the elementary human actions can be modeled as a sequence of a set of rectangles with different orientations and scales. The activity segmentation is based on Gabor filter-bank features and normalized spectral clustering. The feature trajectories of an action category are learnt from training example videos using dynamic time warping. The combined segmentation and the recognition processes are very efficient as both the algorithms share the same framework and Gabor features computed for the former can be used for the later. We have also proposed a simple shadow detection technique to extract good silhouette which is necessary for good accuracy of an action recognition technique.

The West Shandong Uplift and its adjacent basins, with same evolutional history before Mesozoic, are an important basin-orogenic systems in North China. After late Mesozoic, tectonic differentiation between basin and orogenic belt gradually displayed in the study area. The Boxing sag is a part of Jiyang Depression near to West Shandong Uplift, in which the whole Mesozoic and Cenozoic strata are preserved. Based on the analysis of sedimentary records in the Boxing sag, the Cenozoic structural and sedimentary evolutions in Boxing Sag and its response to Western Shandong uplift are discussed in this dissertation. The main conclusions in this research are presented as follows. Based on Seismic and well logging profile interpretation, fault growth index, thickness difference between bottom wall and top wall and fault activity rate from Eocene to Pliocene are studied. Boxing sag had three main faults, NE, NW and NEE trending faults. Research shows that the activity of the NW trending fault in the Boxing sag became weaken from E1-2S4 to N2m gradually. The evolution of NE and the NEE trending fault can be divided into three episodes, from E1-2k to E2s4, from E2s3 to E3s1, from N2m to E3d. The analysis of Paleogene samples of heavy mineral assemblages shows that metamorphic rocks represented by garnet, intermediate-acid igneous rocks represented by the assemblage of apatite, zircon and tourmaline became less from E1-2k to N2g, and sedimentary rocks represented by the assemblage of pyrite, barite and limonite also became less. Intermediate-basic igneous rocks represented by the assemblage of leucoxene, rutile and ilmenite and metamorphic rocks represented by epidote became more and more. Electronic microprobe analysis shows that glaucophane and barroisite are existed in Kongdian Formation and the 4th member of Shahejie Formation, and they demonstrate that Western Shandong and Eastern Shandong are all the source regions of the Boxing Sag, and they also indicate that oceanic crust existed before the collision between the Yangtze and North China continent. The fact that Eastern Shandong is the source region of Boxing Sag also indicates that Western Shandong was not high enough to prevent sediment from Eastern Shandong at E1-2k and E2s4. The results of the dating of five detrital zircons of Boxing Sag show Kongdian Formation and the 4th member of Shahejie Formation have the age peaks of 2800Ma and 700-800. It means that Eastern Shandong is the source region of Boxing Sag at early Paleogene and Western Shandong is not high enough to prevent the sediment from Eastern Shandong. The ages of 160-180 and 220-260 Ma, which exist in the Guantao Formation and Paleogene, are common in Eastern Shandong and rare in Western Shandong,and it implied that Western Shandong is a low uplift at 24Ma. The Paleogene strata have almost same age groups, while the Guantao Formation has significant variations of age groups, and this indicates that Boxing Sag and Western Shandong uplift had taken place tremendous changes. The results of apatite fission track in Boxing sag show that three times uplifts happened at the source region at 60 Ma, 45Ma and 15Ma respectively, and the Boxing sag experienced two subsidences at 60Ma, 45Ma and one uplift at 20Ma.

Based on achievements of thirty years of hydrocarbon exploration, this paper uses the modern theories and methods of sedimentology and oil accumulation to study the origin and distribution features of four sandbodies of Gaoqing, Fanjia, Zhenglizhuang and Jinjia from the third member to the lower second member of Shahejie Formation in detail. Various geophysical methods are also used to explain and to predict the spatial distribution of sandbodies, which further shows mechanism and the model of oil accumulation and illuminates the disciplinarians of oil enrichment and its controlling factors in the study area. The most favourable oil pools predicted by this paper have significant economic and social benefits, which has been confirmed by the exploration. The main conclusions and knowledge includes: (1) Resolving the problems, which remain unresolvable for a long time in the western area of Boxing depression, about the original environment and the spatial distribution of sandbodies of Gaoqing, Fanjia, Zhenglizhuang and Jinjia, and illuminating their relationships. It is suggested that two deltas or delta-related sandbody sediments, which include the delta sandbodies of Jinjia and Gaoqing and their frontal turbidite fan sandbody, are developed in the second and third members of Shahejie Formation. The sandbodies of Fanjia, Gaoqing and Zhenglizhuang are components of Gaoqing delta and belong to the sediments of various periods in different part of the delta. Whereas, the sandbody of Jinjia belong to the Jinjia delta or fan-delta created by the uplift of the Western Shandong and in some areas shows the features of juxtaposition, superimposed deposition and fingeration with the sandbodies of Gaoqing and Zhenglizhuang. (2)Proposing that the sandbodies of different origins in the deltas of Gaoqing and Jinjia have obvious different reservoir qualities, among which the delta frontal bedded sandbodies in the second member of Shahejie Formation in Zhenglizhuang are the best ones and the turbidite sandbody of Fanjia is relatively worse. This shows the direction of further reservoir prediction. (3) According to modern petroleum system theory and continental pool-formation theory, the author divided the western area of Boxing depression into the Jinjia—Zhenglizhuang—Fanjia nose structure belt pool-formation system and the Gaoqing fracture belt pool-formation system. The study area is predominantly located in the former belt and subdivided into pool-formation sub-systems of Zhenglizhuang-Fanjia and Jinjia, which have the source rock of mudstone and oil shale from the upper forth member and the third member of Shahejie Formation in Boxing depression. The hydrocarbon migration and accumulation are controlled by Jinjia-Zhenglizhuang-fanjia nose structure and Gaoqing fracture. (4)Proposing that compared with the best developed sandbodies and traps in the west area of Boxing, the source from the Boxing depression is not sufficient, which is the fundamental reason that the hydrocarbon resources in mid-west area is less than in the east of Boxing. (5) Under the direction of the new theory (fluid compartments theory) and new method of modern pool-formation mechanism, two kinds of pool-formation model are established in study, i.e. inner-compartment model and outer-compartment model. The former has abnormal pressure and is the antigenic source seal pool-forming mechanism, whereas the latter has normal pressure and is of the allochthonous source opening pool-formation mechanism. (6)The study shows that the four sandbodies of Gaoqing, Fanjia, Jinjia and Zhenglizhuang sand are all very benefit for pool-formation, among which the Fanjia sandbody is the best favourable one and is likely to form lithological reservoir and fault-lithological reservoir. But the main step of exploration in Gaoqing, Zhenglizhuang sandbodies should be finding out the fault block, reversed roof and stratum-lithological oil reservoir. (7)Established a set of guidelines and techniques for the research and exploration in the large scale of sandbodies. Proposing that the various traps related to reversed fault and basin-ward fault should be found in step slopes and gentle slopes respectively, and the lithological oil reservoir should mainly be found in the sandstone updip pinch out. It is also suggested that Fanjia sandbody is most favourable to form the lithological and fault-lithological and the Gaoqing, Zhenglizhuang and Jinjia sandbodies have the potential of forming fault block, reversed roof and stratum-lithological oil reservoir. (8) Interpretation and prediction the spatial distribution of main sandbodies based on various geophysical methods suggestion that Fanxi, Gao28 south and Gao27 east have better exploration potential.
