精品课程是国家教育部关于高等学校教学质量和教学改革工程的重要内容,是衡量高等学校教学质量和人才培养质量的标杆之一,精品课程建设在高等医学教学工作中具有重要的地位。法医病理学是一门应用学科,是法医学专业的主干课程,法医病理学教材中部分内容单调、枯燥,在教学中紧靠教材上知识,很难调动起学生的热情。传统教学方法虽然可以系统讲解基本理论知识,但属灌输式教学,不利于发挥学生的主观能动性和培养学生的思维。采用案例教学法,以学生为中心,理论联系实践,提高学生分析问题和解决问题的能力,有组于学生实践能力的培养,提高了法医病理学教学质量,值得推广及应用。  相似文献

We have studied freely flying and walking flies as well as flies flying in a flight simulator in order to discover how functionally blinding one of the eyes affects the fly's ability to move straight. It is hard to tell just by observing the animals' movements whether they have been deprived of vision in one eye. Statistical analysis is need to show that there are differences in the locomotory paths of monocular and binocular flies: monocular flies tend to turn slightly towards the side of the seeing eye. It is possible that the superimposed translational and rotational optic flow fields, generated on the trajectory of monocular flies, sum to zero net flow. This overall flow over the retina of the open eye might lead to a state of optomotor equilibrium. Accepted: 11 October 1999  相似文献

This article discusses the relevance of recent developments in neurobiology for the study of art worldwide. It is argued that both anthropologists and art historians can gain a better understanding of species-specific art and art practices over time and space by broadening their vision and approaches, building on the fundamental and exciting findings concerning art in neurobiology.  相似文献

Forensic anthropology represents a dynamic and rapidly evolving complex discipline within anthropology and forensic science. Academic roots extend back to early European anatomists but development coalesced in the Americas through high-profile court testimony, assemblage of documented collections and focused research. Formation of the anthropology section of the American Academy of Forensic Sciences in 1972, the American Board of Forensic Anthropology in 1977/1978 and other organizational advances provided important stimuli for progress. While early pioneers concentrated on analysis of skeletonized human remains, applications today have expanded to include complex methods of search and recovery, the biomechanics of trauma interpretation, isotopic analysis related to diet and region of origin, age estimation of the living and issues related to humanitarian and human rights investigations.  相似文献

This special issue suggests that the need to examine the entangled lives of species, selves and other beings through a multisensory perspective is crucial and timely. Developing on a sensory analysis, one that emerges through what Anna Tsing refers to as the ‘arts of noticing’ (2015), this introductory paper explores how both nonhuman and human lives are intertwined, and how their close examination can guide anthropologists in their ability to capture the subtleties of more‐than‐human engagement, connection and relatedness. Through articles within this issue from Australian anthropology and beyond, we ask how becoming‐with more‐than‐humans helps us to construct a post‐humanist analysis in the combination of sensory anthropology and multispecies anthropology. Through a combination of these two fields, the paper suggests, anthropology can take up the opportunity to think about animals as subjects, through our ability to communicate beyond language and to engage in a more meaningful way through interspecies knowledge‐making.  相似文献

Biomechanics is the set of tools that explain organismal movement and mechanical behavior and links the organism to the physicality of the world. As such, biomechanics can relate behaviors and culture to the physicality of the organism. Scale is critical to biomechanical analyses, as the constitutive equations that matter differ depending on the scale of the question. Within anthropology, biomechanics has had a wide range of applications, from understanding how we and other primates evolved to understanding the effects of technologies, such as the atlatl, and the relationship between identity, society, culture, and medical interventions, such as prosthetics. Like any other model, there is great utility in biomechanical models, but models should be used primarily for hypothesis testing and not data generation except in the rare case where models can be robustly validated. The application of biomechanics within anthropology has been extensive, and holds great potential for the future.  相似文献

The reaction of Cu(II) ions with a sodium salt of new Schiff base ligand NaL1, sodium N-2-methyl pyridine-2-imine benzoate, in alkaline medium produced an imine bond coupled ligand and a novel complex, Na2[Cu(L3)2], L3 = 2,5-di(2-benzoic acid)-4-(2-pyridine)-1-(2-methyl-2-pyridine)-imidazolidine. When the reduced form of the sodium salt of the Schiff base ligand, NaL2, is employed, a simple hexacoordinated copper(II) complex, [Cu(L2)2], [L2] = bis(N-(2-methylpyridine)-2-aminomethylbenzoate), was isolated. The compounds were characterized by spectroscopic methods and the molecular structures of [Cu(L2)2] and Na2[Cu(L3)2] were determined by single-crystal X-ray diffraction methods. Reaction mechanism for the synthesis of, Na2[Cu(L3)2], copper(II) promoted imine bond coupling is proposed and discussed. The redox behavior of [Cu(L2)2] and Na2[Cu(L3)2], studied using cyclic voltammetry and electron paramagnetic resonance spectroscopic methods, are also discussed.  相似文献

Palynology, which is the study of pollen and spores in an archaeological or geological context, has become a well-established research tool leading to many significant scientific developments. The term palynomorph includes pollen of spermatophytes, spores of fungi, ferns, and bryophytes, as well as other organic-walled microfossils, such as dinoflagellates and acritarches. Advances in plant genomics have had a high impact on the field of forensic botany. Forensic palynology has also been used and applied more recently to criminal investigation in a meaningful way. However, the use of pollen DNA profiling in forensic investigations has yet to be applied. There were earlier uses of dust traces in some forensic analyses that considered pollen as a type of botanical dust debris. Pollen grains can be studied for comparative morphological data, clues to unexpected aspects relating to breeding systems, pollination biology and hybridization. This can provide a better understanding of the entire biology of the group under investigation. Forensic palynology refers to the use of pollen and other spores when it is used as evidence in legal cases to resolve criminal issues by proving or disproving relationships between people and crime scenes. This overview describes the various contributions and the significance of palynology, its applications, different recent approaches and how it could be further employed in solving criminal investigations.  相似文献

Medicinal plants are a two-edged sword that might be exploited as a treatment specific dosage, and as deadly poisonous substances to commit murder or suicide when administered in high doses. Forensic experts can collect traces and residual materials from these toxic medicinal plants at a crime scene as forensic evidence. Further, more investigations need to be deeply implemented to in the future to understand the significance of medicinal plants in forensic investigations to detect these criminal offenses. Additionally, to provides a deep understanding of chemical substances that can impact human life positively or negatively with different doses as well as identifying the optimal or overdose concentrations for either treatments or poisonous effects using recent biotechnological approaches. This review aims to illustrate different contributions and the significance of medicinal plants in the field and further employment in the context of forensic science, especially in the Kingdom of Saudi Arabia.  相似文献

The interests of evolutionary anthropologists, behavioral ecologists, and demographers converge on the ecology of human fertility. Ecological conditions influence the optimum pattern of maternal effort. Patterns of abortion, neglect, and infanticide vary with mothers' ability to invest in their children and children's ability to use that investment. As in most other mammals, the ecology of human fertility varies between the sexes: status and resource control are important for males, whereas reproductive value is crucial for females. In pre-industrial societies, and even in monogamous societies in demographic transition, wealthy men had more children than did poorer men. This correlation, often assumed to have disappeared, persists today, with richer men still having more sexual access than others. Sex differences in the ecology of fertility mean that sex of the offspring, as well as birth order, influences parental investment. Because individual fertility varies with environment, it is not surprising that “natural” (uncontrolled) fertility varies across societies or that demographic transitions proceed locally, with occasional reverses, as individuals strive to maximize their lifetime reproductive success in changing, competitive, conditions.  相似文献

Nine rural village communities in the jungle of Brunei, Borneo were studied to ascertain possible effects of rapid social change on the health of the inhabitants. The social mores and religious beliefs of the rural tribes--Iban, Dusun, and Punan--have undergone but little change over many hundreds of years. During the past three decades, however, enormous social pressures for change have envolved from extraordinary economic prosperity of the region, due to the exploitation of large discoveries of oil and gas. Much of the money has been invested in health care, with the result that malaria, typhus and other tropical scourges have been virtually wiped out. Child and maternal mortality have been reduced to the standards of some of the healthiest countries in the world. The young of the formerly illiterate population are being rapidly educated in new schools scattered throughout the nation. New roads are penetrating the jungle and a thriving lumber industry has been established. Motor boats for the rivers, T.V. and even a national airline have been added. Despite these incursions a vigorous proseletizing by the Moslem and to a lesser extent by the Christian church, the villagers have held tenaciously to their ancient animistic beliefs. Living in long houses, they have also been able to maintain a tightly cohesive patriarchal family structure. Against this background there is as yet little or no evidence of the major diseases of Western society--coronary artery disease and hypertension, although most forms of cancer are commonly encountered. Brunei offers a splendid opportunity to test the putative relationship of chronic vascular disease to social structure and a way of life. Future studies may be made prospectively as the almost inevitable breakdown of old customs and patterns of living occurs in the face of rapid modernization.  相似文献

The wind-orientated walk of carrion beetles Necrophorus humator F. was analysed under closed-loop conditions with a walking compensator and under openloop conditions with a paired tread wheel (Fig. 1).
1.  On the walking compensator an animal runs stable courses with a preferred direction relative to an air current (velocity =; 100 cm/s, Fig. 2B-D). A change in the air-current direction causes a corresponding adjustment of the mean walking direction (Fig. 3). Such course adjustment works best for changes in the air-current direction by an absolute value of 90° (Table 2).
2.  Under closed-loop conditions the animal shows deviations of less than ± 45° around its preferred direction relative to the wind (Fig. 2B-D). The characteristic curve which describes the animal's angular velocity as a function of the animal's walking direction relative to the air-current stimulus is therefore revealed only in this angular range (Fig. 3, top).
3.  Under open-loop conditions, however, complete characteristic curves can be obtained because the animal's walking reaction in response to any given angle of air-current stimulus is measurable on the paired tread wheel (Fig. 4). The characteristic curves are approximately sinusoidal functions. They can either show a shift parallel to the ordinale by a superimposed direction-independent constant angular velocity alone or, at the same time, they can independently exhibit an angular shift along the abscissa (Fig. 5).
4.  The walking tracks straighten with increasing air-current velocity (Fig. 6A, insets), i.e. the animal more rapidly compensates deviations from a preferred course. This corresponds to higher amplitudes of the characterisic curve and steeper slopes at the negative zero-crossing point under open- as well as under closed-loop conditions (Fig. 6).
5.  Walking in an air-current field can be explained by a model of the course control system using a feedback loop (Fig. 7). This model operates according to a sinusoidal characteristic function on which is superimposed a Gaussian white noise process of angular velocity which is independent of walking direction. The model produces realistic walking tracks in an air-current field (Fig. 8).
