Objective To investigate sex hormone def.ciency related osteoporosis and ef.icacy of.dif.erent therapies. Methods Orchiectomized and ovariectomized rat models are used to investigate sex hormone def.ciency related osteoporosis and ef.icacy of.dif.erent therapies. A rat vertebral body can be longitudinally divided into central portion, which contain more trabecular bone, and para-endplate portions which contain more compact bone. In matured male and f.male Wistar and Sprague-Dawley rat lumbar spines, we investigated baseline bone mineral density （BMD） characteristics and the dif.erential segmental responses in bone loss within the lumbar vertebral body post gonadal surgery with clinical multidetector computed tomography. Results Para-endplate sections had a higher BMD than central sections. The cephalad para-endplate sections had a higher BMD than the caudad para-endplate sections. Eight weeks af.er gonadal removal, there was more bone loss in central sections than para-endplate sections. The relative dif.erence of.bone loss between para-endplate and central sections was more apparent in male rats than in f.male rats. There was more bone loss in caudad sections than cephalad sections; this lead to a f.rther increase of.BMD dif.erence between caudad para-endplate sections and cephalad para-endplate sections post gonadal surgery. Conclusion The approach described in this study provided a consistent way to study BMD change within predominantly compact bone portion and trabecular bone portion of.the vertebral body.

Interaction f.rces between sof. magnetic particles in unif.rm and non-unif.rm magnetic f.elds

The inf.uence of.the magnetization of.a sof. magnetic sphere on the surrounding magnetic f.eld is measured and *** interaction f.rce between two sof. magnetic particles is directly measured using an ultra precision load sensor in unif.rm and non-unif.rm magnetic f.elds. The interaction f.rce largely f.llows an inverse f.urth power law as a f.nction of.separation distance between particle centers. At small distances,the ef.ect of.magnetization of.one particle on the magnetization of.its adjacent particle causes the attractive（repulsive） f.rce to be larger（smaller） than that predicted by the inverse f.urth power *** theoretical prediction based on a modif.ed dipole model,that takes into account the coupling ef.ect of.the magnetization among sof. magnetic particles,gives excellent agreement with the measured f.rce in a unif.rm magnetic *** interaction f.rce under a non-unif.rm applied magnetic f.eld can be reasonably predicted using the dipole-dipole interaction model when the local magnetic f.eld is used to determine the magnetization.

Ef.ects of.anthropogenic disturbances on natural regeneration and population structure of.gum arabic tree (Acacia senegal)in the woodlands of.Lake Baringo ecosystem, Kenya

Despite the ecological and economic importance of.Acacia senegal, little is known about the ef.ects of.anthropogenic disturbances on its natural regeneration patterns and population structure. We investigated the ef.ects of.these f.ctors within the Lake Baringo woodland ecosystem. Data was collected f.om 60 plots of.20 m × 20 m systematically distributed in f.ur A. senegal-dominated populations within the Lake Baringo woodland. Sample populations spanned a degradation gradient measured by a population disturbance index (PDI). Trees were measured f.r diameter at breast height (DBH) and categorized by growth stages: seedling, sapling and adult tree. Higher seedling and sapling densities were recorded in lightly than heavily disturbed populations, but only sapling density was signif.cantly dif.erent between the two disturbance levels (P = 0.02). Lightly disturbed populations revealed a reversed J-shape size-class distribution (SCD) indicative of.stable structure unlike the heavily disturbed populations. The quotient and permutation indices indicated unstable populations with episodic recruitment and mortality. Our study reveals that natural regeneration and population structure of.A. senegal were af.ected majorly by selective harvesting and heavy browsing. Suitable management strategies to control livestock grazing and illegal tree harvesting within the woodland is required to promote conservation of.the species genetic resources

Why Hollywood Hates Business： Immanuel Kant＇s Role in Avatar.＂ Movie Reviewed by Adam Smith

引用

Journal of.Philosophy Study 2013年第6期3卷 470-480页

作者： james f. Pontuso Hampden-Sydney College

One of.cinematic science f.ction＇s most popular plot lines is to imagine an invasion of.earth by an advanced alien species. james Cameron＇s Avatar turns the tables on that premise. Humans attack a peacef.l, less technologically sophisticated race in order to exploit their natural resources. Driving the assault is a mining company hell-bent on improving its bottom line. The villain of.Avatar is not a person, but those people who seek prof.t. To put it starkly, business is evil. But why has the entertainment business cast business as a heavy？ Hollywood has now made Immanuel Kant as the director of.moral sentiment. Not, of.course, directly, but rather the ghostwriter of.Hollywood＇s ideas about morality. The works of.Kant are not discussed or debated in the public arena, but their principles have inf.uenced the way people think about what is just and good. The ideas of.Kant have f.ltered into the contemporary discourse and are one of.the key ingredients in the national dialogue over what it means to be moral. The categorical imperative holds that an action is moral only if.it is f.ee f.om calculation of.reward or gain. To be truly, moral people must abandon all practical considerations of.need or desire; they must be directed by pure good will alone. Business people can never measure up to Kant＇s standard. They always make choices based on cost and benef.t. Their businesses would quickly go bankrupt, if.they made decisions on good will rather than interest. Kant＇s principles have raised the moral standard so high that even the common inclination to seek one＇s own benef.t is looked on with some mistrust. In Kantian-inf.uenced movies, business people have come to play the evil antagonist; they seek gain instead of.the good. How would Adam Smith, the f.ther of.economic rationality, respond to popularized Kantian morality？

Marx＇s Concept of.Alienation： With a Brief.Assessment

引用

Journal of.Philosophy Study 2015年第1期5卷 1-15页

作者： james f. Pontuso Hampden-Sydney College

Since the collapse of.Euro-Communism in 1989, the ideas of.Marx have largely been discarded as little more than historical relics. There is a good reason f.r the neglect. The governments that Marxism spawns are among the most brutal in history. Equally condemnable f.r a philosopher who bases his theory on a science of.historical development, most of.Marx＇s key predictions turn out to be incorrect. What then is lef. of.Marx＇s principles？ This paper argues that Marx is best understood as a critic of.the injustice of.industrial societies. Marx＇s essential critical concept is alienation. The paper presents the f.rst complete analysis of.Marx＇s treatment of.alienation and of.ers a brief.assessment of.how this concept applies to our time.
