This essay draws attention to the Prison Reentry Industry’s potential to create unprecedented employment opportunities for formerly incarcerated individuals. Situated at the intersection of money, programming, and state-sponsored surveillance, the Prison Reentry Industry (PRI) is notable for its implication in prolonging and deepening people’s entrenchment in the criminal justice/reentry matrix; however, the burgeoning of a “reentry industry” also ensures the growth of employment positions tailored perfectly to the experiences of formerly incarcerated individuals. The PRI’s production of significant employment opportunities for certain members of the formerly incarcerated population turns social science research on incarceration and employment on its head. It is by now almost conventional wisdom that a criminal history stands as a barrier to employment, but the PRI’s potential to create a substantial job market for formerly incarcerated people may engender an extraordinary outcome in which a criminal record represents for some, the factor leading to entrée into the ranks of the employed.  相似文献

The largely unsolved problems in the theoretical analysis of differentiation and ageing involve a substantial component of linguistic (semantic) difficulties. Some of these are simple traps of ambiguity, resulting from metaphorical or analogical employment of established terms—for example, “terminal differentiation” (loss of division potential in vitro) as a borrowing from “differentiation” as used by developmental biologists, or “commitment” by analogy with “determination”. Some difficulties represent a failure to adopt (at least provisionally) an operational (empirical) view—for example, failure to ask what is the nature of the evidence for the view that a fertilized ovum is totipotential, or to scrutinize the evidence for the view that cells “terminally differentiated” in vitro in a conventional medium are in fact moribund under all conditions, or to examine more closely the view that the differentiated state and the cycling state are mutually exclusive.With respect to the problem of ageing, we review some of the critical experiments on ”terminal differentiation” or “clonal senescence”. We then proceed to consider some of the models that have been proposed, including a molecular model proposed by the author which appears to overcome some of the objections to other models. Some of the models exemplify the results of what are ultimately semantic vices.The problems with which these remarks began should indeed yield to the immense and novel resources of molecular biology. But the development of complete analyses demands not only good luck and delicate technique but also critical semantic clarity and severity. Given the best tools, we shall solve major theoretical problems only if we understand quite fully what problem it is that we are trying to solve—and the history of science illustrates that this is not as elementary a matter as it sounds. For the working scientist semantics (and indeed all philosophy of science) is not an indulgence or a frill, but a basic technical resource.  相似文献

The three categories of the seafloor highs provided for in Article 76 of the 1982 United Nations Convention on the Law of the Sea should be interpreted from the legal perspective and in light of the principle of the natural prolongation. “Oceanic ridges of the deep ocean floor,” which are not part of the natural prolongation of the land territory of the coastal state, are the submarine features that have no geomorphological continuity with the landmass of the coastal state. “Submarine elevations,” which are not only part of the natural prolongation of the land territory of the coastal state but also the natural component of the continental margin, are those submarine features that have geomorphological as well as geological continuity with the landmass of the coastal state. “Submarine ridges,” which are part of the natural prolongation of the land territory of the coastal state but not the natural component of the continental margin, are those submarine features that have geomorphological continuity with the landmass of the coastal state. There are some clear trends as well as obvious variances in the practice of the Commission on the Limits of the Continental Shelf in this regard.  相似文献

Dynamics of coupled Social-Ecological Systems (SES) result from the interplay of society and ecology. To assess SES resilience, we constructed an Agent-Based Model (ABM) of a land use system as a stereotypical example of SES and investigated how resilience of the represented system is affected by both external disturbances and internal dynamics. The model explicitly considered different aspects of resilience in a framework derived from literature, which includes “resilience to”, “resilience of”, “resilience at”, “resilience due to”, and “indicators of resilience”. External disturbances were implemented as shocks in crop yields. Internal dynamics comprised of two types of social interaction between agents (learning and cooperation), an ecological feedback of soil depletion and an economic feedback of agglomeration benefits. We systematically varied these mechanisms and measured indicators that reflected spatial, social, and economic resilience. Results showed that (1) internal mechanisms increased the ability of the system to recover from external shocks, (2) feedbacks resulted in different regimes of crop cultivation, each with a distinctive set of functions, and (3) resilience is not a generic system property, but strongly depends on what system function is considered. We recommend future studies to include internal dynamics, especially feedbacks, and to systematically assess them across different aspects of resilience.  相似文献

A supertwist liquid crystalline luminescent solar concentrator (LSC) “smart” window is fabricated which can be switched electrically between three states: one designed for increased light absorption and electrical generation (the “dark” state), one for transparency (the “light” state), and one for enhanced haziness (“scattering” state). In the scattering state, the absorption and edge emissions decrease while the face emissions are enhanced. This new LSC “smart” window state can find application as a privacy feature in housing, but could also allow for a new “smart” window application as a diffuse glazing to increase plant growth in horticultural applications.  相似文献

Prior to differentiation, embryonic stem (ES) cells in culture are maintained in a so-called “undifferentiated” state, allowing derivation of multiple downstream cell lineages when induced in a directed manner, which in turn grants these cells their “pluripotent” state. The current work is based on a simple observation that the initial culture condition for maintaining mouse ES cells in an “undifferentiated” state does impact on the differentiation propensity of these cells, in this case to a neuronal fate. We point out the importance in judging the “pluripotency” of a given stem cell culture, as this clearly demonstrated that the “undifferentiated” state of these cells is not necessarily a “pluripotent” state, even for a widely used mouse ES cell line. We partly attribute this difference in the initial value of ES cells to the naïve-to-primed status of pluripotency, which in turn may affect early events of the differentiation in vitro.  相似文献

European integration is based upon the promise to bring prosperity by creating economic and social equilibrium among member states and its regions via integrationist policies jointly managed by states and the institutions of the EU. As one common market initiative for greater economic integration in the wider region, goods circulate without tariff and customs duty barriers in the EU’s common customs area. Turkey, not an EU member, has been in this common market since 1996. The EU-Turkey Customs Union, which promised to bring deeper economic and political integration through eventual Turkish membership, represents Turkey’s aspirations to move from the periphery of Europe into its core. As an anthropological contribution to investigations of advanced European capitalism, this paper examines fundamental conflicts of interest between the EU and Turkey and locates them in their unequal power relations and in the disjuncture of each side’s overall objectives from economic integration. Most importantly, it shows that these interest conflicts have ramifications at the individual bureaucratic level and in daily bureaucratic practice. Dramatic expressions of Turkish state power, which are initially geared toward balancing out power inequities, exacerbate Turkish and EU officials’ failures to maintain at least a facade of mutually sustainable interests. Interpreted by EU officials as Turkish bureaucratic inertia, such disintegration of interests has implications for ongoing economic integration and membership negotiations between the two parties, with Turkish officials experiencing loss of control. The paper calls for a critical political economy that pays due attention to the cultural settings in which the former is embedded.  相似文献

Referring to the case studies of two cities in Northern Italy, this article seeks to understand how Bangladeshi migrants use associations to seek transnational “ways of belonging” and “ways of being”. It analyses how this transnational attachment to their home country has played an important role in building their own “community”. The findings reveal that Bangladeshi migrant organizations work to maintain “transnational ways of belonging” by enabling migrants to retain their cultural roots; this is reflected in their observation of festivals, national days, and other practices and rituals. Although, as a relatively new migrant community, they do not share as many economic links through these associations as many other “diasporic” organizations, migrants widely express a sense that these economic connections are with their country of origin. However, there is competition within the community based on regional origin, as well as have many ambivalences and contradictions.  相似文献

A structural model of the triggering of mitosis is described. It is proposed that the number of structural effectors varies discontinuously both just before mitosis through an “all-or-none event” and during the mitotic process itself. The effector persists from mitosis to mitosis, but is not active in G2 due to the polymerization of soluble monomers. The “all-or-none event” which triggers mitosis is postulated to involve the doubling of the number of the structural effectors which are then temporarily in an active state, thus initiating mitosis. The subsequent segregation during mitosis of the active structural effectors to the two dividing nuclei allows the initiation of S phase as soon as the chromosomal replicative machinery is ready.  相似文献

“Thinking too much”, and variations such as “thinking a lot”, are common idioms of distress across the world. The contextual meaning of this idiom of distress in particular localities remains largely unknown. This paper reports on a systematic study of the content and cause, consequences, and social response and coping related to the local terms |x’an n|a te and |eu-ca n|a te, both translated as “thinking a lot”, and was part of a larger ethnographic study among the Khwe of South Africa. Semi-structured exploratory interviews with community members revealed that “thinking a lot” refers to a common experience of reflecting on personal and interpersonal problems. Consequences were described in emotional, psychological, social, behavioral, and physical effects. Coping strategies included social support, distraction, and religious practices. Our contextualized approach revealed meanings and experiences of “thinking a lot” that go beyond a psychological state or psychopathology. The common experience of “thinking a lot” is situated in socio-political, economic, and social context that reflect the marginalized and displaced position of the Khwe. We argue that “thinking a lot” and associated local meanings may vary across settings, may not necessarily indicate psychopathology, and should be understood in individual, interpersonal, community, and socio-political dimensions.  相似文献

Some authors (mainlyBonik, Gutmann, andPeters) have tried to revise current evolutionary concepts, fraught — in their opinion — with “1paleodarwinistic dogmas”. Some points of their theories are reviewed critically in the present paper: (1) Evolution is of course inimaginable without selection, but an “internal selection” eliminating misshaped embryos has nothing to do with evolution. This is stabilizing selection which reduces genetic variation and would even block evolutionary change completely if it was perfect. When this kind of internal selection was “neglected” by earlier authors, this cannot be qualified as paleodarwinistic dogmatism being in contradiction with the premises of evolutionary theory. — (2) Energetic rationalisation of organisms is certainly an important factor in selection but not an absolute law explaining everything about evolution. There are many adaptive processes resulting in less “economic” formations; e.g. heavy armors like those of tortoises, ankylosaurs, and stegosaurs. Among others, protective functions justify a certain waste of energy. — (3) Comparing organisms with technical machines provides an interesting analogy, but again this cannot be considered as the only possible approach for evolutionary models. »Maschinenanalogie« combined with a generalized »internal selection« (i.e. with the nature of adaptive changes determined by the internal construction of organisms) leads inevitably to an underestimation of selective pressures resulting from the ecologic and biocoenotic context. The simple fact of diverging evolutionary lineages shows that the same species (“machine”) can be improved in different ways under the influence of different external factors.  相似文献

Is a dream a meteorite—a bit of material arriving from a distant place that needs to be carefully analyzed to give us knowledge about that place (outside or inside us)? Is it a strange text which has come to us in a foreign language, that needs to be translated into our own? This “meteorite view” is held by some religious and spiritual persons, by many orthodox psychoanalysts and other therapists, and implicitly by many researchers. They all see the dream as something alien, something totally different from our ordinary mental functioning. This paper presents a great deal of research favoring an alternate view—that the dream is an earth-stone, not an alien stone. It may be impressive and beautiful (gemstone), but it's still an earth-stone. The dream is part of our mental functioning. It is one end of a continuum, running from focused waking thought, through looser thought, fantasy, daydreaming, reverie and dreaming. We review reasons why dreams are often considered “totally different”: they're perceptual, not conceptual; they're bizarre; they are “so real”; they're so easily forgotten; they're involuntary; they occur in REM sleep—a totally different state. We demonstrate that none of these reasons are persuasive. In each sense, there is overlap between dreams and other forms of functioning. The continuum view leads to different kinds of research and a different style of dreamwork. It also helps answer questions the field has long struggled with including: Should we study “a dream” or “dreaming”? Are dreams meaningful or meaningless?

For decades, industry groups and many media outlets have propagated the notion that environmental protection is bad for business. However, missing from this public debate has been a detailed accounting of the U.S. economic output and employment that are created through conservation, restoration, and mitigation actions, which we call the “Restoration Economy.” In this paper, we review related literature, including 14 local and state‐level case studies of privately funded environmental restoration projects. We also review federal and state government programs that fund restoration throughout the United States, revealing the complex nature of this sector. We find growing evidence that the restoration industry not only protects public environmental goods but also contributes to national economic growth and employment, supporting as many as 33 jobs per $1 million invested, with an employment multiplier of between 1.48 and 3.8 (the number of jobs supported by every restoration job) and an output multiplier of between 1.6 and 2.59 (multiplier for total economic output from investments). The existing literature also shows that restoration investments lead to significant positive economic and employment impacts and appear to have particularly localized benefits, which can be attributed to the tendency for projects to employ local labor and materials. While these initial figures are promising, the extent of environmental restoration activities and benefits at a national level is not yet well understood. Our findings reveal the need for a methodological framework for more accurately and broadly estimating the size of the U.S. restoration sector and its impact on the U.S. economy.  相似文献

ABSTRACT

In China tourism has been promoted not only as a passport to development in general, but also as an effective instrument to help the poor, and to regulate the serious regional disparity between the coastal and inland areas. In practice, tourism has been adopted popularly by local state elites as an important local economic development strategy, especially in poverty-stricken areas. This article studies the pattern of tourism development in China through the historically specific institutional dynamics of mobilizational developmentalism, which is generated from a blending of mobilizational bureaucracy with developmentalism. With the analytical framework of mobilization developmentalism, this article studies a case of “industrialization of tourism” in which the Miao New Year was promoted by a nationally designated poor county as a tourism-led development project. On one hand, this article analyzes how local bureaucrats at various levels of the government responded to the political mobilization of a tourism-led development project. On the other hand, this study explores how local communities respond to tourism projects mobilized from above. This article argues that mobilizational developmentalism shapes a specific set of political, economic and cultural processes among local state elites, tourist operators, and local communities in developing tourism in China.  相似文献

“Life” means “being alive” of special entities, which we call “organisms”. From a physical point of view, living entities are open systems, which exchange matter as well as energy with their surroundings. Against disruptive influences permanently present, they maintain actively and autonomously a steady state far from the thermodynamic equilibrium. This dynamic state of living beings represents a functional order, an internal “organization”. That means that the involved processes one and all must be correlated in such a way that they in sum prevent the breakdown of the living state. Organization implies functionality, which in turn requires structural relationships, and structures require information for their specification. Information in turn presupposes a source, which is constituted in living systems by the nucleic acids. Organisms are unique in having a capacity to use information, which is stored in the nucleic acid and yields the basis for their specific internal organization in its perpetuation: Living beings, and only they, show a self‐maintained organization.  相似文献

Hurricane María devastated Puerto Rico in September 2017, deepening an already dire economic situation and amplifying an ongoing wave of out-migration. In the age of permanent man-made climate change, hurricanes, like extended economic crises, are “big events” produced by the capitalist despoiling of nature and labor, further exposing the dispossessed and displaced to structural violence. A colony of the USA since 1898, perhaps Puerto Rico has now once again “changed forever,” as the popular belief goes in the wake of María. If so, these changes will continually be experienced and enacted differently by subjects unevenly positioned in terms of unequal relationships of power and privilege. I propose an empirically informed research orientation that examines the situation of contemporary working-class Puerto Ricans in terms of their strategic responses to the involution of colonial capitalism. As a dimension of social life, working-classness is not contracting but expanding, in the context of an ongoing “debt crisis” better understood in terms of the self-consumption, or involution, of the modality of colonial capitalism established in Puerto Rico in the 1940s. In this light, strategic actions of working-class Puerto Ricans such as migration, informal labor, and subsistence/domestic production are not evidence of alternate modes of being, but part of the very conditions of working-classness today. I conclude by briefly identifying three areas for future research to flesh out the proposed orientation, focusing in the immediate term on responses to María by working-class communities in the island and the diaspora, in interaction with local and US elites.  相似文献

Following its inclusion in Appendix II of Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES), the harvest, sale and trade of wild ginseng (Panax quinquefolius) for international commerce has been restricted by law in Pennsylvania since the late 1980s. Since then, exports from the state have declined driving the need to better understand the impact of CITES listing and related state and federal laws. Between 2004 and 2010, we conducted a mixed-methods study in Pennsylvania of stakeholder perspectives on state and federal government conservation efforts and experiences relating to enforcement of harvest and trade restrictions. Results from a survey, key informant interviews, and facilitated group discussions indicate widespread support for ginseng conservation efforts but, not with the CITES driven, top-down regulatory approach. It was widely asserted that ginseng stewardship has been, and will continue to be, governed by personal experience, family teachings, and industry norms and not CITES driven restrictions per se. Moreover, study participants were unable to cite instances where prosecution for ginseng-related “crimes” had occurred within their networks and most believed laws are an ineffective deterrent to “bad behavior.” This emic is externally validated by the fact that agency enforcement is constrained by limited personnel and jurisdictional boundaries, not least of which is an inability to enforce on private lands in the state. These findings suggest that a CITES driven regulatory approach has limitations in actually conserving wild ginseng in Pennsylvania, and suggests that this approach should be complemented by stakeholder supported “bottom-up” partnerships involving greater stakeholder participation, such as government-sponsored or supported ginseng planting programs to counter over-exploitation by collectors and/or extirpation resulting from habitat loss.  相似文献

Fragments taken from femalePlatynereis dumerilii are, at an early stage, characterized by small oocytes, unable to develop normal eggs and to complete the epitokous state if deprived of hormone supply from the prostomium. The question remained whether this inability to achieve normal sexual maturity is due to complete lack of common “juvenile brain hormone” or to absence of a special phase-specific “maturation hormone” whose existence has not yet been proved, but suggested on the basis of autoradiographic investigations of neurosecretory brain activity (Müller 1973). New experiments on such fragments demonstrate that fairly normal oogenesis can be induced and a more advanced epitoke formation attained by daily external treatment with dried isolated prostomia taken from juvenile specimens. Thus, there is no need to assume interference of a special “maturation hormone” in sexual development. The treated fragments show normal posterior regeneration followed by fairly normal sexual maturation, even if the supply of “juvenile brain hormone” is not changed throughout the experiment; hence it may be postulated that the fragment itself gradually alters its mode of response to the hormone.  相似文献
