Urban transport planning in a context of demographic, social, economic and technological change

Transport planning necessarily takes into account more than just the immediate time-frame. In the case of urban transport, planning needs to come up with solutions in regard to infrastructure which is expensive and may have a useful life extending over several decades. Therefore, planning must take note of economic, technological, social and demographic changes that influence trips undertaken.The purpose of this article is to explore some of the trends that may well be observed in upcoming decades. The article arrives at the conclusion that, in a period of considerable change and uncertainty, failure to take heed of recent trends may result in the construction of infrastructure that is not always the most appropriate and, what is more, that urban development militates against the efficient operation of public transport and, as a result, is likely to jeopardize the sustainability of cities in the long term.

Social equity and changing production patterns: an integrated approach

In accordance with the mandate it received at the twenty-third session, in this document the secretariat has attempted to delve further into the links among technical progress, international competitiveness and social equity, although it does not, certainly, purport to have exhausted these subjects. Two qualifying remarks are called for here. First, the secretariat is deliberately abstaining from becoming embfoiled in the theoretical aspects of a controversy which has raged for centuries, and particularly since the French revolution, i.e., the debate surrounding the cause-and-effect relationships and possible areas of incompatibility among democratic governance, economic stability, growth and well-being. Rather than concerning itself with doctrine, the secretariat prefers to deal with the realities confronting virtually all the Governments of the region. These realities include the need to resume a sustained (and environmentally sustainable) growth process within the framework of the consolidation of pluralistic, democratic societies -societies that are faced with very real demands to address the many ways in which the majority of the population has been bypassed by development. Secondly, no attempt has been made in this document to provide a list of suitable policies for changing production patterns or for attaining greater social equity. Instead, the focus is on how certain pivotal analytical and policy aspects can be linked within an integrated approach so as to reinforce any existing areas of complementarity between efforts to achieve greater growth and efforts to seek greater social equity. This approach highlights the central tenet of the document: that growth, social equity and democracy can be compatible. What is more, there are significant but as yet largely unexplored areas in which social equity and changing production patterns complement and reinforce one another.

Social Cognition and Interaction Training (SCIT) for Individuals with Schizophrenia Spectrum Disorders in Outpatient Treatment Settings

The role of social cognition in severe mental illness (SMI) has gained much attention, especially over the last decade. The impact of deficits in socio-cognitive functioning has been found to have detrimental effects on key areas of day-to-day functioning in individuals with SMI, such as gaining and maintaining employment and overall experienced quality of life. Treatment of individuals with SMI is challenging, as the presentation of individual signs and symptoms is rather heterogeneous. There are several treatment approaches addressing deficits ranging from broader social and interpersonal functioning to neurocognitive and more intrapersonal functioning. As research in the domain of social cognition continues to identify specific deficits and its functional detriments, treatment options need to evolve to better target identified functional deficits. Social Cognition and Interaction Training (SCIT) was recently developed to address specific socio-cognitive deficits in an inpatient population of individuals with schizophrenia-spectrum disorders. This study applied SCIT in an outpatient SMI population as many deficits remain after individuals’ symptoms are less severe and overall functioning is more stable than during the acute inpatient phase of their rehabilitation. Specifically, this study has two objectives. First, to demonstrate that deficits in social cognition persist after the acute phase of illness has abated. Second, to demonstrate that these deficits can be ameliorated via targeted treatment such as SCIT. Data was gathered in local outpatient treatment settings serving a heterogeneous SMI population.

Community Life and Housing in Rural Nebraska: 2005 Nebraska Rural Poll Results

Many rural communities are experiencing population decline. However, rural residents have continued to show a strong attachment to their communities. How do rural Nebraskans feel about their community? Are they satisfied with the services provided? Do they own their home? What is the condition of their home? This report details 2,851 responses to the 2005 Nebraska Rural Poll, the tenth annual effort to understand rural Nebraskans’ perceptions. Respondents were asked a series of questions about their community and housing. Trends for some of these questions are examined by comparing data from the nine previous polls to this year’s results. For all questions, comparisons are made among different respondent subgroups, that is, comparisons by age, occupation, region, etc. Based on these analyses, some key findings emerged: Rural Nebraskans’ views of the change in their community are similar to those expressed last year. This year, 28 percent believe their community has changed for the better, compared to 26 percent last year. And, in 2005, only 20 percent think their community has changed for the worse, compared to 22 percent last year. The proportion of expected movers who plan to leave the state decreased this year. Last year, 56 percent of the persons planning to move from their community expected to leave the state. That proportion decreased to 47 percent this year. Rural Nebraskans living in or near the largest communities are more likely than persons living in or near the smaller communities to say their community has changed for the better. Thirty-nine percent of persons living in or near communities with populations of 10,000 or more believe their community has changed for the better during the past year, but only 15 percent of persons living in or near communities with less than 500 people share this opinion. The community services and amenities that rural Nebraskans are most dissatisfied with include: entertainment, retail shopping and restaurants. At least one-third of rural Nebraskans express dissatisfaction with these three services. They are most satisfied with parks and recreation, library services, basic medical care services, highways and bridges, and education (K - 12). At least one-half of rural Nebraskans are satisfied with the following items in their community: appearance of residential areas (66%), crime control (61%), maintenance of sidewalks and public areas (57%) and noise (54%). Rural Nebraskans generally have positive views about their community. Sixty percent agree that their community is an ideal place to live and 52 percent say their community has good business leaders. Rural Nebraskans have mixed opinions about the future of their community. Fortyfour percent agree that their community’s future looks bright, but 42 percent disagree with this statement. Fourteen percent have no opinion. Rural Nebraskans living in or near the larger communities are more likely than residents of the smaller communities to think their community’s future looks bright. Fifty-nine percent of persons living in or near communities with populations of 10,000 or more agree with this statement, compared to only 25 percent of residents living in or near communities with less than 500 people. Further, 61 percent of the residents of the smallest communities disagree with this statement, compared to only 28 percent of the residents of the largest communities. Over three-quarters of rural Nebraskans disagree that younger residents of their community tend to stay there after completing high school. Seventy-six percent disagree with this statement, 16 percent have no opinion and eight percent agree that younger residents stay after completing high school. When comparing responses by age, younger persons are more likely than older persons to agree that younger residents stay in their community after high school. Sixteen percent of persons age 19 to 29 agree with this statement, compared to only six percent of persons age 50 to 64. Younger persons are more likely than older persons to be planning to move from their community next year. Fifteen percent of persons between the ages of 19 and 29 are planning to move next year, compared to only two percent of persons age 65 and older. An additional 17 percent of the younger respondents indicate they are uncertain if they plan to move. Most rural Nebraskans own their home. Eighty-four percent of rural Nebraskans own their home. Older persons are more likely than younger persons to own their home. Eighty-eight percent of persons over the age of 50 own their home, compared to only 52 percent of persons age 19 to 29. Housing in rural Nebraska has an average age of 50 years. Twenty-four percent of residences were built before 1930. Another 24 percent were built between 1930 and 1959. Twenty-nine percent were built between 1960 and 1979 and the remaining 24 percent were built in 1980 or later. The housing stock in smaller communities is older than the housing located in larger communities. Over one-third (35%) of the residences in communities with less than 1,000 people were built before 1930. Only 12 percent of the homes in communities with populations of 10,000 or more were built in this time period. Most rural Nebraskans appear satisfied with their home. Only 24 percent say the current size of their home does not meet their needs. The same proportion (24%) say their home is in need of major repairs. Thirty-eight percent agree that their home needs a lot of routine maintenance, but 87 percent like the location (neighborhood) of their home. One-third of rural Nebraskans living in or near the smallest communities say their home is in need of major repairs. Only 19 percent of persons living in or near communities with populations of 5,000 or more are facing this problem. Home ownership is very important to most rural Nebraskans. Eighty-two percent believe it is very important to own their home. An additional 12 percent say it is somewhat important and six percent say it is not at all important. However, persons who do not currently own their home do not feel it is important for them to do so. Only 32 percent of renters say it is very important to own their home, compared to 91 percent of home owners. And, 35 percent of renters say it is not at all important to own their home.

Syntax of social life in postpartum depression: Mother-child interaction

Purpose: Understand the difficulties and experienced of individuals suffering from postpartum depression, related to mood disturbances, the mother-child bond and its repercussions in the meanings established for the experience of being a mother. Methods: Forty-one patients were interviewed, with ages ranging from 20 to 49 years, from a total of 106 attended at the Primary Care Unit, in the interior of the state of Parahiba, Brazil. A sample of 21 women was selected, presenting an inclusion profile, propitious to mapping postpartum depression. The eligible patients were referred by two PSF (Health Family) teams (one each from the urban and rural zones), aimed at diagnosing the psychic disturbance of the perperium. They were accompanied by a psychologist and all signed an informed consent form. A field diary supported the information recorded. Beck's Depression Inventory complemented the inclusion and follow-up of the patients. The data were analyzed statistically. Results: We confirmed the findings of the most recent studies that infant abandonment in the postpartum period occurs in situations where multiple and serious factors add up, such as misery (86.7%), little schooling (67%), lack of a support network (36.5%), estrangement of the mother's family relations (12%) and lack of paternal involvement (91.5%). Conclusion: The feeling of psyching pain and suffering, resulting from postpartum depression, is the most emphasized by women (87%) because it triggers the greatest discomfort, due to the difficulty in overcoming it.

Dilthey: The hermeneutics of life and the universal aspirations of pedagogy

Dilthey claimed that first psychology and then hermeneutics played the foundational role for his philosophy of life, whose main practical goal is to develop a pedagogy or theory of education. Pedagogy needs help from h ethics to establish its ends, and from psychology to indicate it means. This paper intends to show the relationship between Dilthey's hermeneutics of life and his pedagogy. Dilthey's philosophy of life, in so far it adopts the hermeneutical procedure, engages in the understanding of or the search for the meaning of human socio-historical creations, by adopting a special type of relationship between parts and whole. It is exactly within this hermeneutical balance that we propose to extinguish any indication of a rupture, breach, or contradiction between the quest for universal principles of human behavior and :Dilthey's defense of the impossibility of constructing human moral tasks by means of universal principles. Dilthey began his ethics lectures at the University of Berlin in 1890. These lectures, published in 1958 by Herman Nohl in volume X of Dilthey's collected works, indicate the direction of the trajectory by which formative or social ethics are consolidated as a historical solution for reaching universal principles that can guide human purposes. This trajectory is a result of the distinctively human exercise of self-reflection, by means of which we can fulfill our destiny of manifesting and exteriorizing in time the immanent energy of the absolute spirit. We wish to show that it is possible that such a pedagogy can respect its universal task of orienting the historical development of the younger generation without directing this process by means of fixed and rigid aims.

Cognitive and affective processes in social actions and decisions

The question of how we make, and how we should make judgments and decisions has occupied thinkers for many centuries. This thesis has the aim to add new evidences to clarify the brain’s mechanisms for decisions. The cognitive and the emotional processes of social actions and decisions are investigated with the aim to understand which brain areas are mostly involved. Four experimental studies are presented. A specific kind of population is involved in the first study (as well as in study III) concerning patients with lesion of ventromedial prefrontal cortex (vmPFC). This region is collocated in the ventral surface of frontal lobe, and it seems have an important role in social and moral decision in forecasting the negative emotional consequences of choice. In study I, it is examined whether emotions, specifically social emotions subserved by the vmPFC, affect people’s willingness to trust others. In study II is observed how incidental emotions could encourage trusting behaviour, especially when individuals are not aware of emotive stimulation. Study III has the aim to gather a direct psychophysiological evidence, both in healthy and neurologically impaired individuals, that emotions are crucially involved in shaping moral judgment, by preventing moral violations. Study IV explores how the moral meaning of a decision and its subsequent action can modulate the basic component of action such as sense of agency.

Mikrosomale Biotransformation von Benzo[ghi]perylen, einem mutagenen polyaromatischen Kohlenwasserstoff ohne das Strukturelement der Bay-Region des kanzerogenen Benzo[a]pyrens

Kanzerogene polyaromatische Kohlenwasserstoffe (PAKs), wie Benzo[a]pyren, besitzen eine Bay-Region mit ortho-kondensiertem Benzoring. Dadurch ist die enzymatische Bildung von Bay-Region-Dihydrodiolepoxiden (Oxiranylring in der sterisch abgeschirmten Molekülbucht) möglich, die als ultimal kanzerogene Metaboliten der PAKs gelten. Diese lösen durch DNA-Modifikation Primärläsionen aus, die, sofern sie nicht enzymatisch repariert werden, bei der DNA-Replikation Fehler verursachen (Mu-tationen). Der Mehrstufenprozeß der Kanzerogenese (Promotion und Progression) führt schließlich zur neoplastischen Entartung der Zelle. Benzo[ghi]perylen (BghiP) repräsentiert eine Gruppe von PAKs, die keine „klassische“ Bay-Region besitzen und daher keine vicinalen Dihydrodiolepoxiden bilden können. Trotzdem ist BghiP mutagen, z. B. in den Stämmen TA98 und TA100 von Salmonella typhimurium (1,3- bzw. 4,3 his+-Revertanten/nmol) nach metabolischer Aktivierung mit der postmitochondrialen Fraktion von Ratten nach Behandlung mit 3-Methylcholanthren. Hemmung der mikrosomalen Epoxidhydrolase (mEH) mit 1,1,1-Trichlor-2-propenoxid (TCPO) steigert die bakterielle Mutagenität von BghiP im Stamm TA98 um das 4-fache, was Arenoxide als ultimale Mutagene wahrscheinlich macht. Dieses Ergebnis wird au-ßerdem durch Untersuchung der DNA-Bindung mit dem Verfahren des 32P-Postlabelings bestätigt (Dr. Fickler, Institut für Toxikologie, Universität Mainz). Danach bildete mikrosomal aktiviertes BghiP drei Addukte (ein Hauptaddukt, zwei Nebenaddukte), die durch Hemmung der mEH mit TCPO verstärkt wurden (das Hauptaddukt um 29%). Um den für die bakterielle Mutagenität von BghiP verantwortlichen Metaboliten zu identifizieren, wurde die mikrosomale Biotransformaton von BghiP aufgeklärt. Umsetzung von BghiP mit Lebermikrosomen von Ratten nach Behandlung mit Aroclor 1254 lieferte 17 mit Ethylacetat extrahierbare Metaboliten. Zwölf dieser Metaboliten konnten durch eine Kombination von chromatographischen, spektroskopi-schen und biochemischen Methoden identifiziert werden. Daraus ergeben sich zwei Biotransformati-onswege: Weg I beginnt mit einem Angriff von Cytochrom P450-abhängigen Monooxygenasen an Position 7 und der Bildung des 7-Phenols. Dieses wird dann in das 7,8- bzw. 7,10-Diphenol überführt, die schließlich zu den mehrkernigen Chinonen an der 7,8- bzw. 7,10-Position oxidiert werden. Im Bio-transformationsweg II werden die K-Regionen von BghiP durch Cytochrom P450 funktionalisiert. Zu-nächst entstehen das auf indirektem Weg identifizierte 3,4-Oxid und das 3,4,11,12-Bisoxid, die in mikrosomalen Umsetzungen von BghiP nur nach Hemmung der mEH gebildet werden. Enzymatische Hydrolyse des 3,4-Oxides ergibt das trans-3,4-Dihydrodiol, das zum 3,4-Chinon oxidiert wird. Ebenso entsteht aus dem 3,4,11,12-Bisoxid das trans-3,4-trans-11,12-Bisdihydrodiol, aus dem durch Oxidati-on das trans-3,4-Dihydrodiol-11,12-Chinon hervorgeht. Untersuchung der stereoselektiven enzymati-schen Bildung der K-Region-trans-Di¬hydrodiole ergaben eine präferentielle Entstehung der 3R,4R- bzw. 3R,4R,11R,12R-Enantiomere. Untersuchungen der bakteriellen Mutagenität der Hauptmetaboliten 3,4-Dihydrodiol und dem 7-Phenol machte deutlich, dass beide Biotransformationswege I und II von BghiP zur bakteriellen Mutagenität beitragen. Das 7-Phenol aus Weg I ist ein proximales Mutagen, was auch von Phenolen anderer PAKs bekannt ist. Das 3,4-Dihydrodiol aus Weg II wird so schwach zu Mutagenen aktiviert, dass dem vermutlich gebildete 3,4-Dihydrodiol-11,12-oxid keine große Bedeutung als ultimales Mutagen von BghiP zukommt. Die Bestimmung der direkten mutagenen Aktivität (ohne metabolische Aktivierung) der mutmaßlich ultimal mutagenen Arenoxide von BghiP ergab, dass die des 3,4,11,12-Bisarenoxides sehr gering war (1,3 his+-Revertanten/nmol im Stamm TA98). Das 3,4-Oxid hingegen bewirkte einen deutlichen gentoxischen Effekt in den Stämmen TA98 und TA100 (5,5 bzw. 10 his+-Revertanten/nmol). Dies wurde durch die Bestimmung der DNA-Bindung mit dem 32P-Postlabeling, in dem das 3,4-Oxid für das Hauptaddukt von BghiP verantwortlich gemacht werden konnte, bestätigt. Daher kommt dem 3,4-Oxid als ultimales Mutagen die größte Bedeutung für die Gentoxizität von BghiP zu. Die Ergebnisse dieser Arbeit lassen bei PAKs ohne Bay-Region auf Arenoxide schließen, die eine notwendige Voraussetzung für DNA-Bindung und Mutagenität sind.

(De)colonization through topophilia: Marjorie Kinnan Rawlings’s life and work in Florida

(De)colonization Through Topophilia: Marjorie Kinnan Rawlings’s Life and Work in Florida attempts to reveal the author’s intimate connection to and mental growth through her place, namely the Cross Creek environs, and its subsequent effect on her writing. In 1928, Marjorie Kinnan Rawlings and her first husband Charles Rawlings came to Cross Creek, Florida. They bought the shabby farmhouse on Cross Creek Road, trying to be both, writers and farmers. However, while Charles Rawlings was unable to write in the backwoods of the Florida Interior, Rawlings found her literary voice and entered a symbiotic, reciprocal relationship with the natural world of the Cracker frontier. Her biographical preconditions – a childhood spent in the rural area of Rock Creek, outside of Washington D. C. - and a father who had instilled in her a sense of place or topophilia, enabled her to overcome severe marriage tensions and the hostile climate women writers faced during the Depression era. Nature as a helping ally and as an “undomesticated”(1) space/place is a recurrent motif throughout most of Rawlings’s Florida literature. At a time when writing the American landscape/documentary and the extraction of the self from texts was the prevalent literary genre, Marjorie Kinnan Rawlings inscribed herself into her texts. However, she knew that the American public was not yet ready for a ‘feminist revolt’, but was receptive of the longtime ‘inaudible’ voices from America’s regions, especially with regard to urban poverty and a homeward yearning during the Depression years. Fusing with the dynamic eco-consciousness of her Cracker friends and neighbors, Rawlings wrote in the literary category of regionalism enabling her to pursue three of her major aims: an individuated self, a self that assimilated with the ‘master narratives’ of her time and the recognition of the Florida Cracker and Scrub region. The first part of this dissertation briefly introduces the largely unknown and underestimated writer Marjorie Kinnan Rawlings, providing background information on her younger years, the relationship toward her family and other influential persons in her life. Furthermore, it takes a closer look at the literary category of regionalism and Rawlings’s use of ‘place’ in her writings. The second part is concerned with the ‘region’ itself, the state of Florida. It focuses on the natural peculiarities of the state’s Interior, the scrub and hammock land around her Cracker hamlet as well as the unique culture of the Florida Cracker. Part IV is concerned with the analysis of her four Florida books. The author is still widely related to the ever-popular novel The Yearling (1938). South Moon Under (1933) and Golden Apples (1935), her first two novels, have not been frequently republished and have subsequently fallen into oblivion. Cross Creek (1942), Rawlings’s last Florida book, however, has recently gained renewed popularity through its use in classes on nature writers and the non-fiction essay but it requires and is here re-evaluated as the author’s (relational) autobiography. The analysis through place is brought to completion in this work and seems to intentionally close the circle of Rawlings’s Florida writings. It exemplifies once more that detachment from place is impossible for Rawlings and that the intermingling of life and place in literature, is essential for the (re)creation of her identity. Cross Creek is therefore not only one of Rawlings’s greatest achievements; it is more importantly the key to understanding the author’s self and her fiction. Through the ‘natural’ interrelationship of place and self and by looking “mutually outward and inward,”(2) Marjorie Kinnan Rawlings finds her literary voice, a home and ‘a room of her own’ in which to write and come to consciousness. Her Florida literature is not only product but also medium and process in her assessment of her identity and self. _____________ (1) Alaimo, Stacy.

Caregivers' Social Capital and Satisfaction with their Children's Service Providers

The authors examine children's access to and caregiver's satisfaction with organizations that provide leisure time activities for children on Saturdays. The authors argue that access and satisfaction are a function of familie's financial, cultural and social capital. Using data on 1,036 households in the Phoenix metropolitan area in 2003-04, the authors found that families' financial and cultural capital affected whether or not children participate din activities organized by organizations, but family ties to the organization directly (e.g., either worked there, volunteered, donated) resulted in caregivers being more satisfied with the services. The authors also found that the benefits of network closure (caregivers knowing the parents of other children on site) were greater the riskier the activities of the child (e.g., sports or cheerleading). Contrary to the authors expectations, having family or friends in the area did not affect caregiver's satisfaction with the child's provider.

Questions of Life and Death

The research started with a definition of the general ethical background to be applied in bioethical discussions, particularly regarding aspects of morality that have to be enforced by the community. Only those moral beliefs that can be accepted by consensus in a free discussion can be enforced. It follows that the basic principle of a well ordered society is the equality (and possible upwards extension) of the basic liberties. Therefore, whenever it is possible to respect the principle of autonomy in matters of bioethics (here including questions of abortion, assisted procreation, genetics, organ transplantation and euthanasia) this must be done. On the other hand, there are some common values that can be defended in a free dialogue, values that are needed in order to guarantee stable cooperation in a political society. These values include the respect for human life, which implies the respect for human life in all its forms. This leads to the conclusion that people who are able to be part of the system of cooperation in a political society have rights which are dominant in moral considerations. In all cases where there is no conflict between these rights and the value of life as manifested in human individuals who are not able participate in social cooperation, considerations of the value of the life of the latter must be an important moral consideration. This implies that embryo experimentation should be permitted in order to develop scientific advances needed to save human life, but embryos must not be used for trivial reasons or for the cosmetic industry.
