Benchmarking airports from a managerial perspective

Benchmarking airports is currently popular both in the academic literature and in practice but has proved rather problematic due to the heterogeneity inherent in any reasonably sized dataset. Most studies either treat the airport production technology as a black box, or separate the terminal and airside activities, assessing them individually. In this article we analyze airports as a single unit due to the direct complementarities, thus avoiding the artificial separation of inputs. Using data envelopment analysis (DEA), we open the black box in which a network describes the production process, thus demonstrating the sequential effects that separate final from intermediate outputs, including those under partial managerial control and those that are known to be non-discretionary. To further improve the benchmarking process, we identify appropriate peers for a case study of 43 European airports over 10 years, through a restricted reference mechanism according to pre-defined characteristics. Compared to basic DEA models, the results of the proposed structure provide more meaningful benchmarks with comparable peer units and target values that are potentially achievable in the medium term. By identifying each unit's individual reference set, unique outliers influence the performance measurement less severely than occurs under basic DEA. In addition, the formulations produce an implementation path that moves the airport towards the Pareto frontier gradually, taking into account the regulatory and business environment in which the unit is located.     

The “fetus-infant”: Changing classifications ofIn Utero development in medical texts

This paper examines several aspects of the changing cultural classifications of reproduction through a close reading of obstetrics textbooks. Through the discursive construction of the fetus in obstetric texts, medical accounts are beginning to classify the fetus as a baby. In investigating this transformation, I focus upon two cognitive processes: the splitting of the fetus apart from the pregnant woman and the concurrent lumping of two distinct mental entities—a fetus and an infant into one new medical category: the fetus-infant. In addition, textual evidence shows a shift in cognitive orientation away from classifying fetuses based on gestational age to an emphasis on what I term functional age. Further, new knowledge enables physicians to affect functional age, making the fetus with mature function in utero conceptually no different from a baby. An earlier version of this paper was presented at the American Sociological Association Meeting, Washington, DC, August, 1995.     

Mandates for a changing practice: PSRO and P.L. 94-142.

Federal legislation in the fields of education and health care now requires the development of systems of professional accountability. This accountability to the sponsoring system and to the client is making profound changes in practice. Implications of these changes are reviewed with a challenge to social workers to assume leadership in translating these changes into effective practice models.     

After the Storm: How Race,Class, and Immigration Concerns Influenced Beliefs About the Katrina Evacuees*

Objective. In September 2005, approximately 150,000 Gulf Coast residents fled to Houston, Texas, seeking shelter following Hurricane Katrina. Since the majority of evacuees were poor African Americans, the political and social consequences of the storm inspired a national dialogue on race and class. However, in Houston, the discourse on Katrina evacuees also involved immigration concerns. The city's distinction as a gateway to new arrivals influenced the dialogue on the evacuees' impact on the local area. This article assesses the extent to which race, class, and immigration concerns influenced Houstonians' beliefs about the Katrina evacuees. Methods. We analyze data from the 2006 and 2008 Houston Area Survey in order to assess attitudes toward these newcomers at two distinct time periods: within six months of their arrival and then again more than two years later. Results. Our findings show that both national and local factors influenced beliefs about the Katrina evacuees. Conclusions. The dynamics of race/ethnicity and apprehension toward immigrants drove largely antagonistic beliefs about the mostly poor, mostly black new arrivals.     

Entwicklung ländlicher Kommunen

Due to a revision of the land utilisation plan the town Lichtenberg had initiated a civic participation. After four official workshops the citizens decided to continue on their own. The article describes a best practice example of a citizen’s action committee. The citizens develop concepts and work pro bono for their community. Their aim is to prepare the town for future challenges. The citizen’s action committee works closely together with the town’s council. In the meantime there are three projects that have been finished successfully. One project–the development of a shared vision–is described more detailed. The author summarizes experiences that could be beneficial for other citizen’s action committees.     

Parental sensitivity and friendship development: The mediating role of cooperation

Interactions with mothers and fathers form a critical foundation for youths’ later peer relationships. This study focused on the associations of maternal and paternal sensitivity in third grade with friendship outcomes in sixth grade. Because interactions with parents provide the earliest opportunities for children to learn prosocial behaviors such as cooperation, and cooperation is theoretically conceptualized as a foundation of friendship, cooperation may play a role in the link between parenting and children’s later social relationships. Using the National Institute of Child Health and Human Development Study of Early Child Care and Youth Development sample (N = 955; 51% female; 83% White), and a multimethod, multireporter longitudinal design, children’s cooperation was tested as a mediating mechanism that linked parental sensitivity to early adolescent friendship. Results indicated that most indirect paths from both mothers and fathers’ sensitivity to observed friendship interactions and perceived friendship quality, via cooperation, were significant. Findings provide a more concrete understanding of how parental sensitivity translates to better friendships.     

Social work students’ professional and personal exposure to social work: an Australian experience

General career research suggests that many factors may influence how people select a career, including information about or exposure to the career. The focus of this paper is upon how exposure to a social worker personally (e.g. friend or family) or in a therapeutic capacity (e.g. received social work therapy) may influence the decision to become a social worker, when compared to other disciplines. The results showed that 63% of 64 social work students had personal and/or professional exposure to social work prior to making a career decision. When compared to other students (n?=?447) the social work students were significantly more likely to have accessed social work services (themselves or a family member). The influence of a friend who was a social worker and working with a social worker was noteworthy for mature-aged students. These results highlight that every interaction social workers have with the community provides valuable information about the profession and gives insight into social work as a career. Additionally, the results suggest that the increase in numbers of social workers and the influence of that exposure to a social worker have resulted in an increase in the use of social work services by students, and may continue to rise in the future.     

Review and Evaluation of the J100-10 Risk and Resilience Management Standard for Water and Wastewater Systems

Risk analysis standards are often employed to protect critical infrastructures, which are vital to a nation's security, economy, and safety of its citizens. We present an analysis framework for evaluating such standards and apply it to the J100-10 risk analysis standard for water and wastewater systems. In doing so, we identify gaps between practices recommended in the standard and the state of the art. While individual processes found within infrastructure risk analysis standards have been evaluated in the past, we present a foundational review and focus specifically on water systems. By highlighting both the conceptual shortcomings and practical limitations, we aim to prioritize the shortcomings needed to be addressed. Key findings from this study include (1) risk definitions fail to address notions of uncertainty, (2) the sole use of “worst reasonable case” assumptions can lead to mischaracterizations of risk, (3) analysis of risk and resilience at the threat-asset resolution ignores dependencies within the system, and (4) stakeholder values need to be assessed when balancing the tradeoffs between risk reduction and resilience enhancement.     

Qualitative insights into women's personal experiences of perinatal depression and anxiety

Background and aimSymptoms of perinatal depression and anxiety are usually described and understood from a nosological perspective. This research sought to gain insight into women's lived experience of postnatal depression and anxiety, the factors that contribute to these symptoms and the context in which they develop.MethodFace to face and telephone interviews were conducted with 28 women from metropolitan and rural areas across Australia, who had experienced postnatal depression and/or anxiety within the last five years. Analysis was conducted from a grounded theory perspective.FindingsParticular symptoms of anxiety and depression develop in the context of the numerous changes inherent to the transition to motherhood and contribute to a common experience of frustration and loss. Symptoms were also associated with feelings of dissatisfaction with the pregnancy and motherhood experience.ConclusionsThe findings provide useful insights into women's experiences of mental health symptoms during the perinatal period, how these symptoms present and the factors involved in their development and maintenance. The need to consider women's perspectives to develop resources and health promotions strategies, as well as within the context of relationships with health professionals is highlighted. The study emphasizes the need for greater, more accurate information surrounding perinatal depression and the need to increase the profile and awareness of anxiety disorders.
