Green infrastructure (GI) is gaining wide popularity as a means to reduce urban stormwater runoff. The challenges to long-term success of many GI policies, however, depend on citizen understanding and willingness to be engaged in the process of GI implementation. In this study, we developed a conceptual model that incorporated human preferences and biophysical processes in a coupled manner to estimate stormwater runoff variation at the sewershed scale under different acceptable GI implementation scenarios. To investigate resident receptivity toward GI implementation, we conducted surveys in selected Syracuse sewersheds and developed the scenario of residents implementing rain barrels and rain gardens in their private properties based on the survey results. We simulated this scenario at the lot level using the model we developed within the framework of the EPA SWMM 5 model to estimate reductions in peak flow and total runoff volume for major storm events. With our model, we also tested the effect of planned government tree planting scenarios. The scenario simulations were applied in three urban sewersheds of varying socio-economic and biophysical structures in the City of Syracuse, New York. The simulation results indicated that both the “government participation” and “household participation” scenarios, compared to pre-GI-development conditions, would contribute to a modest reduction in stormwater peak flow (>4 %) and total runoff volume (>5 %) across the simulated sewersheds. This study provides decision makers with a scientific methodology to quantify how human decisions can shape ecosystem function, and thus support sustainable stormwater management planning while addressing citizen preferences and needs.  相似文献

There is no consensus on a comprehensive classification for green infrastructure (GI). This is a consequence of the diversity of disciplines, application contexts, methods, terminologies, purposes and valuation criteria for which a GI typology is required. The aim of this systematic literature review is to evaluate the existing evidence on how GI is being categorised and characterised worldwide. We reviewed a total of 85 studies from 15 countries that were analysed for contextual trends, methods, parameters and typologies. Results show that relevant literature lacks a common terminology and that a universal typology for all scenarios is impractical. Analysis reveals that GI can be organised into four main GI categories: (a) tree canopy, (b) green open spaces, (c) green roofs and (d) vertical greenery systems (facades/walls). Green open spaces and tree canopy attracted the attention of researchers due to their complexity, variability and important roles in GI planning. Evidence suggests that a ternary approach in terms of the functional (purpose, use, services), structural (morphology) and configurational (spatial arrangements) attributes of GI should be applied for a more comprehensive classification. Although this approximation is inherently generic, since it can be used across different research disciplines, it is also sufficiently specific to be implemented for individual scopes, scenarios and settings. Further research is needed to develop a typology capable of responding to particular research aims and performance analyses based upon the findings discussed in this paper.  相似文献

The commodity nature of green coffee is the main cause of the ‘coffee paradox’ (falling producer prices and rising consumer prices). Geographical Indications (GIs) may be an effective ‘decommodifier’ of the coffee market, but many constraints have to be overcome. Based on an analysis of how the characteristics of the coffee production system shape the positions of local stakeholders and, thus, the GI building process, this article identifies some constraining factors that can seriously undermine the capacity the GI has to decommodify the market and attain a fairer distribution of the benefits for local producers.  相似文献

Geographical indications (GIs) are place‐based names that convey the geographical origin, as well as the cultural and historical identity, of agricultural products. GIs are unique, in that they provide a means of ensuring that control over production and sales of a product stays within a local area, but at the same time they make use of extralocal markets. Although control over GIs largely rests with local actors, GIs are nested in wider regional, national, and international networks; and the passage from local to extralocal markets introduces new costs and benefits and new relations of power into the supply chain. The degree to which GI protection spurs development and protects local environmental and cultural resources depends on the structure of the GI legislation and on the territorial context in which protection is embedded. Using a commodity‐chains approach, I compare two GI production systems, tequila in Mexico and Comté cheese in France, in order to develop a theory of the factors that contribute to more sustainable, equitable GI production systems. I argue that three key differences in the design of the GI schemes help to explain the varying effects of the two cases: (1) the manner in which supply‐chain actors define quality, (2) the way that the GI valorizes the terroir of the region, and (3) the strength and cohesion that the collective organizing body exhibits. Moreover, the institutional and political context in which GI supply chains “touch down” plays a critical role. Contrary to a conceptualization of GIs as compatible with a purely market‐oriented model, my comparison of these two cases indicates that some level of state involvement, in order to level the playing field and empower small farmers, is a necessary, although not sufficient, precondition for successful and sustainable GIs.  相似文献

This article describes one of the first accounts of an Employee Assistance Program (EAP) staffed by a social worker in industry in the United States. The author was the social worker employed in this EAP (called the Industrial Social Work Project) which was originally motivated by a vice president's concern over employee turnover. The article describes in detail how the EAP was operationalized and used to evaluate the organizational culture by using an organizational development model which involved five overlapping phases. These were: (1) orientation/information gathering; (2) individual treatment; (3) research on cultural change; (4) team building and O.D. projects; and (5) O.D. management training. The main contention of this article is that organizations do in fact contribute to the "professional suicide" of employees, and those who plan to evaluate ENS are remiss not considering the organization context of such programs and their possible impact on employees.  相似文献

Diminishing motor function is commonly observed in the elderly population and is associated with a wide range of adverse health consequences. Advanced Glycation End products (AGE’s) may contribute to age-related decline in the function of cells and tissues in normal ageing. Although the negative effect of AGE’s on the biomechanical properties of musculoskeletal tissues and the central nervous system have been previously described, the evidence regarding the effect on motor function is fragmented, and a systematic review on this topic is lacking. Therefore, a systematic review was conducted from a total of eight studies describing AGE’s related to physical functioning, physical performance, and musculoskeletal outcome which reveals a positive association between high AGE’s levels and declined walking abilities, inferior ADL, decreased muscle properties (strength, power and mass) and increased physical frailty. Elevated AGE’s levels might be an indication to initiate (early) treatment such as dietary advice, muscle strengthening exercises, and functional training to maintain physical functions. Further longitudinal observational and controlled trial studies are necessary to investigate a causal relationship, and to what extent, high AGE’s levels are a contributing risk factor and potential biomarker for a decline in motor function as a component of the ageing process.  相似文献

In this case study, we describe the symptoms, neurological examination, clinical course, and neuropathology of a patient with progressive supranuclear palsy (PSP). PSP is a relatively uncommon neurodegenerative disorder with many features similar to those of Parkinson's disease. It is characterized by slow motor function, ocular movement abnormalities, dystonia, and cognitive disabilities. PSP is largely a sporadic disorder caused by accumulation of the protein tau in diverse regions of the central nervous system. It is thus classified as one of several tauopathies. The exact cause of the disease remains unknown, and treatment is often limited. The following case provides a framework to explore the manifestations of PSP, as well as the progress made in understanding the nature of this challenging disorder.  相似文献

In this paper, we use the case of tequila to examine the potential for geographical indications (GIs) to contribute to socioeconomic and environmental sustainability. GIs are place-based names (e.g., Champagne, Roquefort) that convey the geographical origin, as well as the cultural and historical identity, of agricultural products. The GI for tequila was established by the Mexican government in 1974, making it the oldest GI, and one of the best-recognized, outside of Europe. Here, we examine the social, economic, and ecological impacts that the agave–tequila industry has had on one community in tequila's region of origin, the town of Amatitán. We show that persistent cycles of surplus and shortage of agave and changing production relations in the agave–tequila industry have led to: (1) economic insecurity among farm households; (2) increased use of chemical inputs, at the expense of more labor-intensive cultivation practices; and (3) overall declines in fertilizer application, especially during periods in which there is a surplus of agave. We argue that the negative effects of the agave–tequila industry on the local economy and environment are due to the failure of the GI for tequila to value the ways in which the terroir of tequila's region of origin have contributed to its specific properties. We conclude by using this case to discuss more generally the relationship between the protection of place-based products (known collectively as geographical indications) and social and environmental sustainability.  相似文献

Randall Collins's interaction ritual (IR) theory suggests social solidarity as hardwired in the human neurological capacity for rhythmic entrainment. Yet, this article suggests that IR theory may benefit from being tied more firmly to recent neurobiological research, specifically Stephen W. Porges's polyvagal theory that proposes autonomic nervous system functioning as a basis for emotions and social behavior. In this perspective, IR theory does not sufficiently acknowledge the human nervous system as a system involving a phylogenetically ordered response hierarchy, of which only one subsystem supports prosocial behavior. The ritual ingredients of mutual attention and shared mood may, moreover, be specified as part of a social engagement system, neurally regulating attention and emotional arousal via a face–heart connection. The article suggests that this social engagement system provides part of the neural basis for rhythmic entrainment. The polyvagal theory furthermore challenges IR theory to reconsider the importance of individual biological differences—ritual success may not merely be ascribed to interactional effects, but also to reciprocal causality between situations and neurobiological properties of ritual participants.  相似文献

Functional neurological symptom disorder, alternatively termed conversion disorder (FNSD-CD) (Although the DSM-5 utilises the term 'conversion disorder', practitioners and consumers consider this to be an outdated, unsubstantiated and often stigmatising term. In accordance with this, the current terminology used in the field is 'functional neurological symptom disorder'), involves symptoms of altered voluntary motor or sensory functions without identifiable nervous system disease or pathology. It is considered a psychiatric disorder and is, thus, listed in the Diagnostic and Statistical Manual of Mental Disorders (5th Ed.; DSM-5). As per the nosology of the DSM-5, the discrete behavioural or psychological syndrome or pattern observed in FNSD-CD is assumed to be a function of a problem of, or a disorder within, the individual. Accordingly, the psychiatric approach to FNSD-CD, as set out in the DSM-5, invokes an assumption common to the medical model which is that of lineal (i.e., straight-line) causality, namely, causal events are arranged in a lineal sequence. The interactional approach, however, which is a development of general system theory in the field of family therapy, offers an alternative approach to understanding psychiatric disorders. Specifically, this approach places the emphasis on the relationships between individuals and their reciprocal influences on – including their psychological and emotional wellbeing with – one another. It draws on the assumption of nonlineal (i.e., circular) causality, namely, causal events are arranged in a circular sequence. From an interactional approach, therefore, FNSD-CD is thought to be a function of a problem of, or a deficit within, the individuals’ relationship/s, rather than within an individual, per se. This article utilises a composite case study to investigate FNSD-CD from an interactional approach.  相似文献

The purpose of this study is to assess the initial impact of Licensed Independent Clinical Social Workers (LICSW's) as a new reimbursable provider class in an insured population with mandated nervous and mental benefits. History of nervous and mental therapy, previous provider type, age, and sex are examined. Data were obtained from Blue Shield of Massachusetts' nervous and mental claim information from 1979 through 1982 for all patients who saw a social worker during the year of LICSW certification. Results show (1) a large majority of the 1982 social worker patients had no billable psychiatric experience for the three years prior to 1982; (2) the longer a patient is in treatment, the less likely is a provider type switch; and (3) psychologists' patients are more likely to switch to a social worker than psychiatrists' patients. A concern remains for this insurer over the increase in the total number of psychiatric services concomitant with a new provider class introduction.  相似文献

‘Classical’ genomic progesterone receptors appear relatively late in phylogenesis, i.e. it is only in birds and mammals that they are detectable. In the different species, they mediate manifold effects regarding the differentiation of target organ functions, mainly in the reproductive system. Surprisingly, we know little about the physiology, endocrinology, and pharmacology of progesterone and progestins in male gender or men respectively, despite the fact that, as to progesterone secretion and serum progesterone levels, there are no great quantitative differences between men and women (at least outside the luteal phase). In a prospective cohort study of 1026 men with and without cardiovascular disease, we were not able to demonstrate any age-dependent change in serum progesterone concentrations. Progesterone influences spermiogenesis, sperm capacitation/acrosome reaction and testosterone biosynthesis in the Leydig cells. Other progesterone effects in men include those on the central nervous system (CNS) (mainly mediated by 5α-reduced progesterone metabolites as so-called neurosteroids), including blocking of gonadotropin secretion, sleep improvement, and effects on tumors in the CNS (meningioma, fibroma), as well as effects on the immune system, cardiovascular system, kidney function, adipose tissue, behavior, and respiratory system. A progestin may stimulate weight gain and appetite in men as well as in women. The detection of progesterone receptor isoforms would have a highly diagnostic value in prostate pathology (benign prostatic hypertrophy and prostate cancer). The modulation of progesterone effects on typical male targets is connected with a great pharmacodynamic variability. The reason for this is that, in men, some important effects of progesterone are mediated non-genomically through different molecular biological modes of action. Therefore, the precise therapeutic manipulation of progesterone actions in the male requires completely new endocrine-pharmacological approaches.  相似文献

The aim of this study was to test whether there is statistically significant sympathetic nervous system (SNS) synchrony between participants in couple therapy. To our knowledge, this is the first study to measure psychophysiological synchrony during therapy in a multiactor setting. The study focuses on electrodermal activity (EDA) in the second couple therapy session from 10 different cases (20 clients, 10 therapists working in pairs). The EDA concordance index was used as a measure of SNS synchrony between dyads, and synchrony was found in 85% of all the dyads. Surprisingly, co‐therapists exhibited the highest levels of synchrony, whereas couples exhibited the lowest synchrony. The client–therapist synchrony was lower than that of the co‐therapists, but higher than that of the couples.

Occupational stress is implicated as an etiology for a variety of diseases. Many of the etiological theories surrounding these associations incriminate some deviation of autonomic nervous system activity. New methods of analyzing cardiovascular data obtained from a Holter monitor provide a window into a worker's autonomic nervous system throughout the day, in many cases for two days. These methods allow a variety of comparisons, for example, between workers of varying job stress levels, between work days and rest days, day and night, and between high stress and low stress periods. Identifying altered autonomic nervous system activity patterns throughout the day may: 1. provide insight into the etiology of stress related pathologies; 2. allow quantification of exposure; 3. investigate possible interaction effects of different exposures; 4. lead to monitoring methods capable of identifying whether an employee's job stress is increasing his or her risk for disease.  相似文献

Schore and others have written extensively about the importance of unconscious implicit right brain to right brain communication in (1) driving therapeutic change and (2) understanding and working with the patient’s autonomic nervous system (ANS). Porges, who has re-conceptualized the ANS as a system arranged hierarchically rather than organized around balance, has been extremely influential on clinicians interested in neuroscience. Schore’s and Porges’ theories are discussed in order to make the case that therapist self-disclosure is a powerful and useful technique entirely consistent with their work.  相似文献

Neuro-technical interfaces are technical devices that bridge the electronic world to neurons with the objective to establish a long term stable contact for bidirectional information exchange. What does that mean in detail and to what kind of machine and for what purpose should the central nervous system, i.e. the brain, be connected? Science fiction literature and movies offer a tremendous variety of usually uncomfortable scenarios including cyborg and robocop super-humans and mass control. Do these implants change the psyche in general and what is feasible in nowadays therapeutic and rehabilitative approaches? In this overview, the author will not answer these questions but tries to deliver an overview of the technological background, the opportunities and the limitations of neuro-technical interfaces to the central nervous system. The fundamental specifications for neuro-technical interfaces will be introduced. Different degrees of implant invasiveness will be discussed and lead to a summary of clinical systems with their application-specific complexity. Actual technological opportunities and limitations will be addressed as well as general physical limitations. Current and future scenarios of neuro-technical interfaces to the central nervous system will be presented from an engineering point of view arising some questions that might be of interest with respect to ethical and societal implications when those interfaces are transferred into clinical practice and public applications.  相似文献

Aging is associated with a significant decline in neuromuscular function leading to an eventual loss of independence and mobility of senescent people. Age-related sarcopenia, characterised by a reduction in muscle mass and strength, is considered one of the most striking features of aging at the level of the skeletal muscle. Morphological alterations in skeletal muscle can be considered as one of the consequences responsible for muscle weakness in the aged population. Beyond 60 years of age, human muscle undergoes a process of continuous denervation and reinnervation, due to an accelerating loss of motor units. It appears evident that phenotypic alterations in muscle depend on the motor drives provided by the nervous system. Because the peripheral nerves, the neuromuscular junction and motor neurons exhibit degenerative features during advanced age, sarcopenia does not seem to intrinsically develop, but is rather a secondary effect of impaired neuronal function. It is therefore recommended that elderly subjects undergo an exercise program that is aimed towards the improvement of coordinative skills and of muscle strength.  相似文献

Cancer is the largest cause of death by disease in children under 15, and tumors of the brain and central nervous system are the second most common type. Such tumors sometimes present initially with psychiatric features, and further diagnostic confusions can ensue with hospitalization and treatment. This monograph addresses the devastating impact of an intracranial neoplasm on the emotional life and adaptations of the child, with particular attention to interventions and possible diagnostic problems.The assistance of Dr. Edna F. Roth in the preparation of this article is gratefully acknowledged.  相似文献
