Community participation in health services

This study critically analyzes and synthesizes community participation (CP) theory across disciplines, defining and beginning to map out the elements of CP according to a preliminary framework of structure, process, intermediate outcomes, and ultimate outcomes. The first study component sought to determine the impact of Sight N' Soul, a CP project utilizing neighborhood health workers (NHWs), on appointment missing in an indigent urban African-American population. It found that persons entering the vision care system through contact with an NEW were about a third less likely to miss an appointment than those persons entering the system through some other avenue. While theory in this area remains too poorly developed to hypothesize causal relationships between structure, process, and outcomes, a summary of the elements of Sight N' Soul's structure and process both developed the preliminary framework and serves as a first step to mapping these relationships. The second component of the study uncovered the elements of structure and process that may contribute to a sustained egalitarian partnership between community people and professionals, a CP program called Project HEAL. Elements of Project HEAL's structure and process included a shared belief in the program; spirituality; contribution, ownership, and reciprocation; a feeling of family; making it together; honesty, trust, and openness about conflict; the inevitability of uncertainty and change; and the guiding interactional principles of respect; love, care, and compassion; and personal responsibility. The third component analyzed the existing literature, identifying and addressing gaps and inconsistencies and highlighting areas needing more highly developed ethical analysis. Focal issues include the political, economic, and historical context of CP; the power of naming; the issue of purpose; the nature of community; the power to muster and allocate resources; and the need to move to a systems view of health and well-being, expanding our understanding of the universe of potential outcomes of CP, including iatrogenic outcomes. Intermediate outcomes might include change in community, program, and individual capacity, as well as improved health care delivery. Ultimate outcomes include increased positive interdependencies and opportunities for contribution; improved mental, physical, and spiritual health; increased social justice; and decreased exploitation. ^

Trade Versus Culture in the Digital Environment : An Old Conflict in Need of a New Definition

Following the recent UNESCO Convention on the Protection and Promotion of the Diversity of Cultural Expressions, the first wave of scholarly work has focused on clarifying the interface between the Convention and the WTO Agreements. Building upon these analyses, the present article takes however a different stance. It seeks a new, rather pragmatic definition of the relationship between trade and culture and argues that such a re-definition is particularly needed in the digital networked environment that has modified the ways markets for cultural content function and the ways in which cultural content is created, distributed and accessed. The article explores first the significance of the UNESCO Convention (or the lack thereof) and subsequently outlines a variety of ways in which the WTO framework can be improved in a ‘neutral’, not necessarily culturally motivated, manner to become more conducive to the pursuit of cultural diversity and taking into account the changed reality of digital media. The article also looks at other facets of the profoundly fragmented culture-related regulatory framework and underscores the critical importance of intellectual property rights and of other domains that appear at first sight peripheral to the trade and culture discussion, such as access to infrastructure, interoperability or net neutrality. It is argued that a number of feasible solutions exist beyond the politically charged confrontation of trade versus culture and that the new digital media landscape may require a readjustment of the priorities and the tools for the achievement of the widely accepted objective of cultural diversity.

Wieczna kobiecość i emancypacja kobiet: obraz kobiecości w twórczości Karoliny Světlej

To nie przypadek, że wyrażenie „wieczna kobiecość" ukute przez Goethego zbiega się w czasie z pierwszymi zachodnimi próbami emancypacji kobiet. W chwili, kiedy model kobiety istniejącej tylko w zależności od mężczyzny zaczyna być kwestionowany, kategoria wiecznej kobiecości pozwala ponownie potwierdzić ten model, wypełniając go pozytywnymi wartościami. Naturą kobiety jest być uległą i oddaną, a te cechy sprawiają, że kobieta jest depozytariuszem wszelkiej potencjalnej zbawczej łaski. Tak w Fauście Goethego, przypada Małgorzacie, dziewczynie naiwniej, niewinnej, niewykształconej i bez własnej woli, wykupić Fausta siłą swojej miłości. Wszystko dzieje się tak, jakby pozytywna kodyfikacja właściwości kobiet dzięki kategorii wiecznej kobiecości służyła tylko lepszemu ukryciu rzeczywistości ich ucisku; feministki jednak nie dają się zwieść: ideały popierane przez kategorię wiecznej kobiecości są a priori niezgodne z emancypacją kobiet. Karolina Světlá, jedna z najważniejszych postaci w walce o zrównanie praw między mężczyznami i kobietami w Czechach w XIX wieku, wykorzystywała przecież intensywnie w swojej literackiej twórczości ten model kobiety, która poświęca się dla kochanego mężczyzny i tym samym udaje się jej go "podciągnąć do góry" ("hinan zu ziehen", Goethe) oraz dać mu dostęp do "nieskończoności", "nieśmiertelności" i "wieczności". Czy jej teoretyczne pisma i jej działalność na rzecz emancypacji kobiet zaprzeczałyby jej tekstom literackim, na pierwszy rzut oka tak konwencjonalnym? W tym wykładzie podejmuję próbę odpowiedzi na to pytanie uważną lekturą jednego z jej najbardziej faustowskich opowiadań, mianowice "Czarna dziewanna".

SDR-based Passive Indoor Localization System for GSM

This study deals with indoor positioning using GSM radio, which has the distinct advantage of wide coverage over other wireless technologies. In particular, we focus on passive localization systems that are able to achieve high localization accuracy without any prior knowledge of the indoor environment or the tracking device radio settings. In order to overcome these challenges, newly proposed localization algorithms based on the exploitation of the received signal strength (RSS) are proposed. We explore the effects of non-line-of-sight communication links, opening and closing of doors, and human mobility on RSS measurements and localization accuracy. We have implemented the proposed algorithms on top of software defined radio systems and carried out detailed empirical indoor experiments. The performance results show that the proposed solutions are accurate with average localization errors between 2.4 and 3.2 meters.

From Similes to Allegory: The Deconstruction of Chariot Imagery in Early Buddhist Texts, Analyzed with Cognitive Metaphor Theory

The presentation will start by unfolding the various layers of chariot imagery in early Indian sources, namely, chariots as vehicles of gods such as the sun (sūrya), i.e. as symbol of cosmic stability; chariots as symbols of royal power and social prestige e.g. of Brahmins; and, finally, chariots as metaphors for the “person”, the “mind” and the “way to liberation” (e.g., Kaṭ.-Up. III.3; Maitr.-Up. II. 6). In Buddhist and non-Buddhist sources, chariots are in certain aspects used as a metaphor for the (old) human body (e.g., Caraka-S., Vi.3.37-38; D II.100; D II.107); apart from that, there is, of course, mention of the “real” use of chariots in sports, cults, journey, and combat. The most prominent example of the Buddhist use of chariot imagery is its application as a model for the person (S I.134 f.; Milindapañha, ed. Trenckner, 26), i.e., for highlighting the “non-substantial self”. There are, however, other significant examples of the usage of chariot imagery in early Buddhist texts. Of special interest are those cases in which chariot metaphors were applied in order to explain how the ‘self’ may proceed on the way to salvation – with ‘mindfulness’ or the ‘self’ as charioteer, with ‘wisdom’ and ‘confidence’ as horses etc. (e.g. S I. 33; S V.7; Dhp 94; or the Nārada-Jātaka, No. 545, verses 181-190). One might be tempted to say that these instances reaffirm the traditional soteriology of a substantial “progressing soul”. Taking conceptual metaphor analysis as a tool, I will, in contrast, argue that there is a special Buddhist use of this metaphor. Indeed, at first sight, it seems to presuppose a non-Buddhist understanding (the “self” as charioteer; the chariot as vehicle to liberation, etc.). Yet, it will be argued that in these cases the chariot imagery is no longer fully “functional”. The Buddhist usage may, therefore, best be described as a final allegorical phase of the chariot-imagery, which results in a thorough deconstruction of the “chariot” itself.

Song Choices of Swiss Sathya Sai Baba Devotees

The charismatic and controversial Indian guru Sathya Sai Baba is the centre of attention and devotion for a great number of adherents from various national, religious, and ethnic backgrounds. Due to its global spread, the Sathya Sai Baba movement is an ideal case for examining displaced religious practices. Singing is a vital part of the religious practice of Sai devotees. In this article I will discuss the contents and usage of the songbook that Swiss devotees compiled. We can observe the extent to which Indian contents are carried over and how they are supplemented with Swiss songs, but also with songs perceived as being part of a universal spiritual treasury of songs (e.g. Native American, Hebrew or International Christian songs). I will suggest that the concept of de- and reterritorialization helps us to analyze the practices of this global religious community. Additionally, I will argue that the devotees’ choice of songs and their singing practices are indeed a manifestation of their claim to universalism as well as their need to be rooted locally. I will further argue that a globalized religious movement is limited in dealing with the encounter of diverse cultural contents by the strategy of reterritorialization, but beyond that creates a new and supraterritorial cultural context.

Experimenting and modeling: sharp distinctions, integration or just a mess?

At first sight, experimenting and modeling form two distinct modes of scientific inquiry. This spurs philosophical debates about how the distinction should be drawn (e.g. Morgan 2005, Winsberg 2009, Parker 2009). But much scientific practice casts serious doubts on the idea that the distinction makes much sense. There are two worries. First, the practices of modeling and experimenting are often intertwined in intricate ways because much modeling involves experimenting, and the interpretation of many experiments relies upon models. Second, there are borderline cases that seem to blur the distinction between experiment and model (if there is any). My talk tries to defend the philosophical project of distinguishing models from experiment and to advance the related philosophical debate. I begin with providing a minimalist framework of conceptualizing experimenting and modeling and their mutual relationships. The methods are conceptualized as different types of activities that are characterized by a primary goal, respectively. The minimalist framwork, which should be uncontroversial, suffices to accommodate the first worry. I address the second worry by suggesting several ways how to conceptualize the distinction in a more flexible way. I make a concrete suggestion of how the distinction may be drawn. I use examples from the history of science to argue my case. The talk concentrates and models and experiments, but I will comment on simulations too.

A Passive WiFi Source Localization System based on Fine-grained Power-based Trilateration

Indoor localization systems become more interesting for researchers because of the attractiveness of business cases in various application fields. A WiFi-based passive localization system can provide user location information to third-party providers of positioning services. However, indoor localization techniques are prone to multipath and Non-Line Of Sight (NLOS) propagation, which lead to significant performance degradation. To overcome these problems, we provide a passive localization system for WiFi targets with several improved algorithms for localization. Through Software Defined Radio (SDR) techniques, we extract Channel Impulse Response (CIR) information at the physical layer. CIR is later adopted to mitigate the multipath fading problem. We propose to use a Nonlinear Regression (NLR) method to relate the filtered power information to propagation distances, which significantly improves the ranging accuracy compared to the commonly used log-distance path loss model. To mitigate the influence of ranging errors, a new trilateration algorithm is designed as well by combining Weighted Centroid and Constrained Weighted Least Square (WC-CWLS) algorithms. Experiment results show that our algorithm is robust against ranging errors and outperforms the linear least square algorithm and weighted centroid algorithm.

Range-based Weighted-likelihood Particle Filter for RSS-based Indoor Tracking

Attractive business cases in various application fields contribute to the sustained long-term interest in indoor localization and tracking by the research community. Location tracking is generally treated as a dynamic state estimation problem, consisting of two steps: (i) location estimation through measurement, and (ii) location prediction. For the estimation step, one of the most efficient and low-cost solutions is Received Signal Strength (RSS)-based ranging. However, various challenges - unrealistic propagation model, non-line of sight (NLOS), and multipath propagation - are yet to be addressed. Particle filters are a popular choice for dealing with the inherent non-linearities in both location measurements and motion dynamics. While such filters have been successfully applied to accurate, time-based ranging measurements, dealing with the more error-prone RSS based ranging is still challenging. In this work, we address the above issues with a novel, weighted likelihood, bootstrap particle filter for tracking via RSS-based ranging. Our filter weights the individual likelihoods from different anchor nodes exponentially, according to the ranging estimation. We also employ an improved propagation model for more accurate RSS-based ranging, which we suggested in recent work. We implemented and tested our algorithm in a passive localization system with IEEE 802.15.4 signals, showing that our proposed solution largely outperforms a traditional bootstrap particle filter.

Blind intubation of anaesthetised children with supraglottic airway devices AmbuAura-i and Air-Q cannot be recommended: A randomised controlled trial.

BACKGROUND Paediatric supraglottic airway devices AmbuAura-i and Air-Q were designed as conduits for tracheal intubation. Although fibreoptic-guided intubation has proved successful, blind intubation as a rescue technique has never been evaluated. OBJECTIVE Evaluation of blind intubation through AmbuAura-i and Air-Q. On the basis of fibreoptic view data, we hypothesised that the success rate with the AmbuAura-i would be higher than with the Air-Q. DESIGN A prospective, randomised controlled trial with institutional review board (IRB) approval and written informed consent. SETTING University Childrens' Hospital; September 2012 to July 2014. PATIENTS Eighty children, American Society of Anesthesiologists (ASA) class I to III, weight 5 to 50 kg. INTERVENTIONS Tracheal intubation was performed through the randomised device with the tip of a fibrescope placed inside and proximal to the tip of the tracheal tube. This permitted sight of tube advancement, but without fibreoptic guidance (visualised blind intubation). MAIN OUTCOME MEASURES Primary outcome was successfully visualised blind intubation; secondary outcomes included supraglottic airway device success, insertion times, airway leak pressure, fibreoptic view and adverse events. RESULTS Personal data did not differ between groups. In contrast to our hypothesis, blind intubation was possible in 15% with the Air-Q and in 3% with the AmbuAura-i [95% confidence interval (95% CI) 6 to 31 vs. 0 to 13%; P = 0.057]. First attempt supraglottic airway device insertion success rates were 95% (Air-Q) and 100% (AmbuAura-i; 95% CI 83 to 99 vs. 91 to 100; P = 0.49). Median leak pressures were 18 cmH2O (Air-Q) and 17 cmH2O [AmbuAura-i; interquartile range (IQR) 14 to 18 vs. 14 to 19 cmH2O; P = 0.66]. Air-Q insertion was slower (27 vs. 19 s, P < 0.001). There was no difference in fibreoptic view, or adverse events (P > 0.05). In one child (Air-Q size 1.5, tube size 3.5), the tube dislocated during device removal. CONCLUSION Ventilation with both devices is reliable, but success of blind intubation is unacceptably low and cannot be recommended for elective or rescue purposes. If intubation through a paediatric supraglottic airway device is desired, we suggest that fibreoptic guidance is used. TRIAL REGISTRATION Clinicaltrials.gov identifier: NCT01692522.
