Value of information (VOI) analysis evaluates the benefit of collecting additional information to reduce or eliminate uncertainty in a specific decision-making context. It makes explicit any expected potential losses from errors in decision making due to uncertainty and identifies the “best” information collection strategy as one that leads to the greatest expected net benefit to the decision-maker. This study investigates the willingness to pay for groundwater quality monitoring in the Eocene Aquifer, Palestine, which is an unconfined aquifer located in the northern part of the West Bank. The aquifer is being used by 128,000 Palestinians to fulfill domestic and agricultural demands. The study takes into account the consequences of pollution and the options the decision maker might face. Since nitrate is the major pollutant in the aquifer, the consequences of nitrate pollution were analyzed, which mainly consists of the possibility of methemoglobinemia (blue baby syndrome). In this case, the value of monitoring was compared to the costs of treating for methemoglobinemia or the costs of other options like water treatment, using bottled water or importing water from outside the aquifer. And finally, an optimal monitoring network that takes into account the uncertainties in recharge (climate), aquifer properties (hydraulic conductivity), pollutant chemical reaction (decay factor), and the value of monitoring is designed by utilizing a sparse Bayesian modeling algorithm called a relevance vector machine.

The aims of this study were to assess the current situation regarding glass litter on the streets and children's attitudes, and behavior concerning glass litter. Out of 240 interviewed children, 41.7% admitted glass littering. This was reflected in the high incidence of injuries caused by street glass among children; 140 (58.3%) of the children interviewed had been injured by broken glass at least once while walking outdoors and 95 of the children had received professional medical care for the lacerations. As reported by the children who admitted to glass littering, the most effective elements (29.6%) in preventing them from littering the streets with glass were moral and religious convictions, and the next most effective practice (20.4%) was improved street cleanliness. Preventive measures such as encouraging moral and religious convictions among children, more effective street cleaning by local authorities, improved footwear, education, and glass recycling incentives, as well as engaging the community in street cleaning campaigns, are all needed to address this public health hazard. More recreational facilities should be provided. Public awareness initiatives led by environmentalists, social workers, primary health care providers or home healthcare providers may also help educate children to wear shoes, prevent glass injuries and increase glass litter awareness.
This article reviews the deteriorating health situation of the Palestinian population during the post-Oslo period of the Palestinian Authority and during the current Intifada. It seeks to record findings obtained through primary participants and documents and from personal observations in the field that situate Palestinian health conditions within their political framework. The ongoing crisis highlights longstanding problems in the Palestinian health infrastructure, which make it more vulnerable to Israeli policies, especially the movement restrictions and closures. Efforts by Palestinian professionals and the international health community to provide health services have been constantly thwarted. The Israeli authorities' disregard for Palestinian health care has escalated since 2000 and is directly responsible for a vast number of Palestinian deaths. Israel's indiscriminate obstructions to the coordinated functioning of a health care system in Palestine increase morbidity, degrade health, promote premature deaths, and damage the medical infrastructure. Moreover, the Israeli actions transgress international law and, ultimately, make peace in the region much less likely. This analysis provides further evidence of the social justice violations and the wide-ranging effects on health experienced daily by the Palestinian people as a direct result of the Israeli military occupation.
The aim of the paper is to explore the development of psychiatry in Palestine from two main perspectives: ethnicity and immigration. In Palestine the subject of immigration and psychiatry were highly complicated and had unique features. Thus, both psychiatrists and patients were immigrants who belonged to the same ethnic group sharing the same ideology and objectives. The examination will uncover the social construction of mental diseases among Jewish immigrants in Palestine - patients and psychiatrists - and elucidate another layer in the development of the Zionist Jewish society in Palestine up to the establishment of the State of Israel.
Background Diabetes mellitus is a common chronic metabolic disorder and one of the main causes of death in Palestine. Palestinians are continuously living under stressful economic and military conditions which make them psychologically vulnerable. The purpose of this study was to investigate the prevalence of depression among type II diabetic patients and to examine the relationship between depression and socio-demographic factors, clinical factors, and glycemic control. Methods This was a cross-sectional study at Al-Makhfiah primary healthcare center, Nablus, Palestine. Two hundred and ninety-four patients were surveyed for the presence of depressive symptoms using Beck Depression Inventory (BDI-II) scale. Patients' records were reviewed to obtain data pertaining to age, sex, marital status, Body Mass Index (BMI), level of education, smoking status, duration of diabetes mellitus, glycemic control using HbA1C test, use of insulin, and presence of additional illnesses. Patients’ medication adherence was assessed using the 8-item Morisky Medication Adherence Scale (MMAS-8). Results One hundred and sixty four patients (55.8%) of the total sample were females and 216 (73.5%) were < 65 years old. One hundred and twenty patients (40.2%) scored ≥ 16 on BDI-II scale. Statistical significant association was found between high BDI-II score (≥ 16) and female gender, low educational level, having no current job, having multiple additional illnesses, low medication adherence and obesity (BMI ≥ 30 kg/m2). No significant association between BDI score and glycemic control, duration of diabetes, and other socio-demographic factors was found. Multivatriate analysis showed that low educational level, having no current job, having multiple additional illnesses and low medication adherence were significantly associated with high BDI-II scores. Conclusion Prevalence of depression found in our study was higher than that reported in other countries. Although 40% of the

The objective of this study was to investigate the performance of employing H2O2 reagent in persulfate activation to treat stabilized landfill leachate. A central composite design (CCD) with response surface methodology (RSM) was applied to evaluate the relationships between operating variables, such as persulfate and H2O2 dosages, pH, and reaction time, to identify the optimum operating conditions. Quadratic models for the following two responses proved to be significant with very low probabilities (<0.0001): chemical oxygen demand (COD) and NH3-N removal. The obtained optimum conditions included a reaction time of 116 min, 4.97 g S2O8(2-), 7.29 g H2O2 dosage and pH 11. The experimental results were corresponding well with predicted models (COD and NH3-N removal rates of 81% and 83%, respectively). The results obtained in the stabilized leachate treatment were compared with those from other treatment processes, such as persulfate only and H2O2 only, to evaluate its effectiveness. The combined method (i.e., /S2O8(2-)/H2O2) achieved higher removal efficiencies for COD and NH3-N compared with other studied applications.

To compare the nature and determinants of child discipline in Qatar and Palestine among young adults through retrospective survey to develop legislation, policies and interventions for effective prevention of child maltreatment, and educational materials to promote positive discipline among parents and caregivers. Cross-sectional random household surveys were conducted in each country (Qataris N=697, Palestinians N=2064) using ISPCAN Child Abuse Screening Tool-Retrospective (ICAST-R) for young adults (18-24 years), to investigate child discipline methods into the maltreatment range. Qatari young adults were more educated (p<0.001) and had more full-time employment (p=0.004) than Palestinian young adults. Qatar reported lower physical and emotional abuse compared to their counterparts in Palestine, e.g. Hit/Punch, Kick (p<0.001) and Insult/Criticize, Threaten to be hurt/killed (p<0.001). Qatari participants found any harsh discipline they received in childhood was not reasonable and not justified compared to Palestinian participants. The more advantaged Qatari population was less likely to experience disciplinary methods that experts developing the ICAST-R defined as abuse compared to Palestinians where the higher incidence of child abuse could be attributed to lower economic advantage, lower level of education and greater exposure to violence. Suggestions are made for future studies in Qatar and Palestine to develop survey methodology with a more culturally appropriate level of intrusion, such as indirect yet meaningful child maltreatment questions.

Hospitals and health centers provide a variety of healthcare services and normally generate hazardous waste as well as general waste. General waste has a similar nature to that of municipal solid waste and therefore could be disposed of in municipal landfills. However, hazardous waste poses risks to public health, unless it is properly managed. The hospital waste management system encompasses many factors, i.e., number of beds, number of employees, level of service, population, birth rate, fertility rate, and not in my back yard (NIMBY) syndrome. Therefore, this management system requires a comprehensive analysis to determine the role of each factor and its influence on the whole system. In this research, a hospital waste management simulation model is presented based on the system dynamics technique to determine the interaction among these factors in the system using a software package, ithink. This model is used to estimate waste segregation as this is important in the hospital waste management system to minimize risk to public health. Real data has been obtained from a case study of the city of Nablus, Palestine to validate the model. The model exhibits wastes generated from three types of hospitals (private, charitable, and government) by considering the number of both inpatients and outpatients depending on the population of the city under study. The model also offers the facility to compare the total waste generated among these different types of hospitals and anticipate and predict the future generated waste both infectious and non-infectious and the treatment cost incurred.

Information about the rate of smoking and factors associated with initiating and maintaining the behaviour is scarce in Palestine. The aim of this study was to explore the rate of and attitudes towards smoking among An-Najah National University students. During spring 2010, a questionnaire adopted from the Global Health Professionals Survey and the Global Youth Tobacco Survey was administered to 954 randomly selected full-time students. Overall 34.7% of the study sample were cigarette or waterpipe smokers, and this rate was higher among males than females (52.7% versus 16.5%). In logistic regression analysis, sex (male), type of college (humanities), older age and higher family income were predictors of current smoking status. Smokers had more negative attitudes to banning smoking in public areas on campus and to education about the harmful effects of smoking. Antismoking programmes with special attention to males and students in humanities are badly needed.

Parental concern about childhood fever and consequent use of antipyretics is increasing. Little is known about childhood fever management among Arab parents. No scales to measure parents' fever management practices in Palestine are available. The aim of this study was to validate the Arabic version of the Parent Fever Management Scale (PFMS) using a sample of parents in Palestine. A standard "forward-backward" procedure was used to translate PFMS into Arabic language. It was then validated on a convenience sample of 402 parents between July and October 2012. Descriptive statistics were used, and instrument reliability was assessed for internal consistency using Cronbach's alpha coefficient. Validity was confirmed using convergent and known group validation. Applying the recommended scoring method, the median (interquartile range) score of the PFMS was 26 (23-30). Acceptable internal consistency was found (Cronbach's alpha = 0.733) and the test-retest reliability value was 0.92 (P < 0.001). The Chi squared (χ (2)) test showed a significant relationship between PFMS groups and frequent daily administration of antipyretic groups (χ (2) = 52.86; P < 0.001). The PFMS sensitivity and specificity were 77.67 and 57.75 %, respectively. The positive and negative predictive values were 67.89 and 32.11 %, respectively. The Arabic version of the PFMS is a reliable and valid measure and can be used as a useful tool for health professionals to identify parents' fever management practices. The Arabic version of the PFMS can be used to reduce unnecessary parental practices in fever management for a febrile child.

The existing literature faces difficulties when accounting for the simultaneity of socio-environmental conflict and cooperation. We suggest that this puzzle can be solved by more recent constructivist works, which argue that conflictive or cooperative behavior is driven by discursively constructed interests, identities and situation assessments. Based on a literature review and field interviews, we analyze and compare the dominant water discourses in Israel and Palestine with the discourse dominant among the activists of a water cooperation project between communities from Israel and the West Bank. Our main result is that discourses are indeed crucial for understanding water-related conflict and cooperation. This finding highlights the relevance of constructivist approaches in the study of socio-environmental conflict and cooperation as well as of practices of bottom-up discursive conflict transformation.
Background Radon gas is considered as a main risk factor for lung cancer and found naturally in rock, soil, and water. The objective of this study was to determine the radon level in the drinking water sources in Nablus city in order to set up a sound policy on water management in Palestine. Methods This was a descriptive study carried out in two phases with a random sampling technique in the second phase. Primarily, samples were taken from 4 wells and 5 springs that supplied Nablus city residents. For each source, 3 samples were taken and each was analyzed in 4 cycles by RAD 7 device manufactured by Durridge Company. Secondly, from the seven regions of the Nablus city, three samples were taken from the residential tap water of each region. Regarding the old city, ten samples were taken. Finally, the mean radon concentration value for each source was calculated. Results The mean (range) concentration of radon in the main sources were 6.9 (1.5-23.4) Becquerel/liter (Bq/L). Separately, springs and wells' means were 4.6 Bq/L and 9.5 Bq/L; respectively. For the residential tap water in the 7 regions, the results of the mean (range) concentration values were found to be 1.0 (0.9-1.3) Bq/L. For the old city, the mean (range) concentration values were 2.3 (0.9-3.9) Bq/L. Conclusions Except for Al-Badan well, radon concentrations in the wells and springs were below the United State Environmental Protection Agency maximum contaminated level (U.S EPA MCL). The level was much lower for tap water. Although the concentration of radon in the tap water of old city were below the MCL, it was higher than other regions in the city. Preventive measures and population awareness on radon's exposure are recommended. PMID:22243625

This work presents qualitative and quantitative evaluation of environmental radioactivity in the central and southern areas of the West Bank, Palestine. For this purpose, the technology of in situ gamma-ray spectroscopy is used with a scintillation of 7.6 x 7.6 cm NaI(Tl) crystal connected to multichannel analyzer InSpector 2000 from Canberra instruments and laptop computer. Gamma-ray spectra were collected using the detector placed 1 m above the ground surface. Calibration of the detection system for in situ measurements of gamma-emitting radionuclides in open terrain is performed theoretically using Monte Carlo techniques. Measurements are conducted in 18 locations in 3 regions across the West Bank. The vast majority of identified radionuclides are naturally occurring gamma-emitting sources (the decay products of (238)U, (232)Th and (40)K). The only identified anthropogenic radionuclide is (137)Cs. Activity concentrations of (40)K, (238)U, (232)Th as well as the total outdoor gamma dose rate from these radionuclides were determined from the gamma-ray spectra. The highest activity concentrations of the three primordial radionuclides were 203 Bq kg(-1) for (40)K, 32 Bq kg(-1) for (238)U and 30 Bq kg(-1) for (232)Th. The total outdoor gamma dose rate calculated for the whole study area at 1 m above ground ranged from 6 to 30 nGy h(-1) with a mean of 18 +/- 7 nGy h(-1), which represents about 30% of the world average value.

Objectives Hairdressers are exposed to chemicals at the workplace which are known to cause respiratory symptoms and asthma. This study aimed to examine changes in self-reported respiratory symptoms over 5 years, as well as to examine the lung function decline and determine whether it is within the expected range, to assess the dropout rate and reasons for leaving the profession, and to examine the associations between occupational factors and lung function changes at follow-up. Design Prospective study. Setting Female hairdressing salons in Hebron city, Palestine. Participants 170 female hairdressers who participated in a baseline survey in 2008 were followed up in 2013. A total of 161 participants participated in 2013. Outcome measures Change in reported respiratory symptoms and change in lung function over follow-up. Dropout from the profession and reasons for it. Differences between current and former hairdressers in respiratory symptoms and lung function at follow-up. Ambient air ammonia levels in 13 salons. Results Current hairdressers reported more respiratory symptoms in 2013 compared with baseline. Former hairdressers reported fewer symptoms at follow-up. At follow-up, current hairdressers showed a significant decrease in forced vital capacity of 35 mL/year (95% CI 26 to 44 mL/year) and of 31 mL/year (95% CI 25 to 36 mL/year) for forced expiratory volume in 1 s (FEV1). 28 (16%) of the hairdressers quit the job during the 5-year follow-up, 8 (28%) because of health problems. Hairdressers who had been working for 4 years or more at baseline showed a stronger decline in FEV1 compared with those who worked less than 4 years (difference 13, 95% CI 1 to 25). Conclusions Current hairdressers developed more respiratory symptoms and larger lung function decline than former hairdressers during follow-up. Few hairdressers left their profession because of respiratory health problems. Working for more years is associated with lung function decline among

We examine the creation and functioning of the "Pasteur Institute in Palestine" focusing on the relationship between biological science, health policy, and the creation of a "new society" within the framework of Zionism. Similar to other bacteriological institutes founded by colonial powers, this laboratory was developed in response to public health needs. But it also had a political role. Dr. Leo Böhm, a Zionist physician, strived to establish his institution along the lines of the Zionist aspiration to develop a national entity based on strong scientific foundations. Even though the institute enjoyed several fruitful years of operation, mainly during World War I, it achieved no lasting national or scientific importance in the country. Böhm failed to adapt to new ways of knowledge production, scientifically and socially. The case study of the "Pasteur Institute in Palestine" serves as a prism to view the role of the public health laboratory in the history of Palestine with its ongoing changes of scientific, organizational, and political context.

Understanding the predictors of sustainability in solid waste management (SWM) systems can significantly contribute to eliminate many waste management problems. In this paper, the sustainability elements of SWM systems of interest are (1) attitudes toward separation at the source, (2) behaviour regarding reuse and/or recycling and (3) willingness to pay for an improved service of SWM. The predictors affecting these three elements were studied in two Palestinian cities: Ramallah and Jericho. The data were collected via structured questionnaires and direct interviews with the respondents, and the analysis utilized a logistic regression model. The results showed that the place of residence and dwelling premises are the significant factors influencing attitudes toward separation at the source; the place of residence and age are the significant factors explaining behaviour regarding reuse and/or recycling; while the dwelling premises, gender, level of education and being received education on waste management are the significant factors affecting willingness to pay for an improved service of SWM.
Due to the political context and the restrictions placed on general freedoms and trade union activities, workers' education in Palestine remained informal and largely reliant on oral memory until the early 1990s. For decades, it was an integral part of political education. Workers' education only became a stand-alone field after the establishment…

Seawater intrusion is one of the major threats to freshwater resources in coastal areas, often exacerbated by groundwater overexploitation. Mitigation measures are needed to properly manage aquifers, and to restore groundwater quality. This study integrates three computational tools into a unified framework to investigate seawater intrusion in coastal areas and to assess strategies for managing groundwater resources under natural and human-induced stresses. The three components are a three-dimensional hydrogeological model for density-dependent variably saturated flow and miscible salt transport, an automatic calibration procedure that uses state variable outputs from the model to estimate selected model parameters, and an optimization module that couples a genetic algorithm with the simulation model. The computational system is used to rank alternative strategies for mitigation of seawater intrusion, taking into account conflicting objectives and problem constraints. It is applied to the Gaza Strip (Palestine) coastal aquifer to identify a feasible groundwater management strategy for the period 2011-2020. The optimized solution is able to: (1) keep overall future abstraction from municipal groundwater wells close to the user-defined maximum level, (2) increase the average groundwater heads, and (3) lower both the total mass of salt extracted and the extent of the areas affected by seawater intrusion.

Specific Association of Teratogen and Toxicant Metals in Hair of Newborns with Congenital Birth Defects or Developmentally Premature Birth in a Cohort of Couples with Documented Parental Exposure to Military Attacks: Observational Study at Al Shifa Hospital, Gaza, Palestine
Manduca, Paola; Naim, Awny; Signoriello, Simona
This study was undertaken in Gaza, Palestine, in a cohort of babies born in 2011. Hair samples of newborns were analyzed for metal load by DRC-ICP-MS. We report specific level of contamination by teratogen/toxicants metals of newborn babies, environmentally unexposed, according to their phenotypes at birth: normal full term babies, birth defects or developmentally premature. The occurrence of birth defects was previously shown to be correlated in this cohort to documented exposure of parents to weapons containing metal contaminants, during attacks in 2009. We detect, in significantly higher amounts than in normal babies, different specific teratogen or toxicant elements, known weapons’ components, characteristic for each of birth defect or premature babies. This is the first attempt to our knowledge to directly link a phenotype at birth with the in utero presence of specific teratogen and/or toxicant metals in a cohort with known episodes of acute exposure of parents to environmental contamination by these same metals, in this case delivered by weaponry The babies were conceived 20–25 months after the major known parental exposure; the specific link of newborn phenotypes to war-remnant metal contaminants, suggests that mothers’ contamination persists in time, and that the exposure may have a long term effect.

Background Medical research productivity reflects the level of medical education and practice in a particular country. The objective of this study was to examine the quantity and quality of medical and biomedical research published from Palestine. Findings Comprehensive review of the literature indexed by Scopus was conducted. Data from Jan 01, 2002 till December 31, 2011 was searched for authors affiliated with Palestine or Palestinian authority. Results were refined to limit the search to medical and biomedical subjects. The quality of publication was assessed using Journal Citation Report. The total number of publications was 2207. A total of 770 publications were in the medical and biomedical subject areas. The annual rate of publication was 0.077 articles per gross domestic product/capita. The 770 publications have an h-index of 32. One hundred and thirty eight (18%) articles were published in 46 journals that were not indexed in the web of knowledge. Twenty two (22/770; 2.9%) articles were published in journals with an IF > 10. Conclusions The quantity and quality of research originating from Palestinian institutions is promising given the scarce resources of Palestine. However, more effort is needed to bridge the gap in medical research productivity and to promote better health in Palestine. PMID:23375070

Olive mill wastewater (OMW) is generated seasonally in large amounts during the olive oil production in Palestine, and it is often disposal of in uncontrolled manner into the open environment. OMW has a high amount of phototoxic compounds, high salinity and acidity and therefore is challenging when disposed on soil. The objective of this study was to study the persistence and degree of water repellency during different season of OMW application in soil samples (0-5 cm deep), and to elucidate how extent this phenomenon is associated with soil acidity, to analyze the relationships between soil water repellency and environmental factors including, temperature and moisture and to describe the seasonal variation in the phenol concentration of the soil. In order to understand how climatic conditions at the time of OMW disposal affect the development of soil water repelleny in field, soil acidity and phenol content in soil, we conducted a field study in Bait Reema village in the West Bank - Palestine. The study site is characterized by 1.5 m thick brown rendzina and has an annual average rainfall of 550 mm. On an extensively used olive orchard field, we implemented 16 plots (2.5 x 3.5 m). OMW application (14 L / m2) was conducted either in winter, spring or summer on two replicate plots distributed randomly among the 16 plots. To test the effect of soil moisture on the persistence of OMW effects, we implemented an OMW application in summer on two additional plots, but kept those plots moist before and after OMW application until start of the rain season. For each of the treatment variants, we implemented two control plots which were treated in the same way as their counterparts, but with tap water. Soil samples (0-5 cm) were collected after 2 days, 3 weeks, 6 weeks, 3 months, 6 months , 9 months, 12 months , and 18 months. pH was determined and analyzed in aqueous soil extracts (1:5), the total phenol content was determined by using Folin-Ciocalteu's reagent, soil water
Background Canine visceral leishmaniasis (CVL) is caused by Leishmania infantum in all Mediterranean countries. The Leishmania parasite is transmitted by the bite of a corresponding sand fly vector and primarily maintained in nature by wild and domestic reservoirs, including dogs, foxes and jackals. Infected dogs are the primary reservoir host in endemic regions and are the most significant risk disposing humans to infection. The present study aimed at assessing the prevalence of infection with Leishmania and identification of Leishmania infantum in domestic dogs in the West Bank, Palestine. Methods The infection rate among domestic dogs collected from seven districts in the Palestinian West Bank was investigated by examination of parasites in culture from the buffy coat using serological and molecular methods; based on ELISA, internal transcribed spacer 1 (ITS1) and cysteine protease (CPB) PCR. Results Out of 215 dogs examined for Leishmania, 36 (16.7%) were positive in at least one method. Twenty three animals (11.5%) were positive for Leishmania DNA, whereas, ELISA and culture revealed 16 (7.5%), and 4 (1.5%) respectively. CPB-PCR on one of three culture-positive isolates revealed Leishmania infantum as the causative agent for Leishmania infection in dogs. Conclusions Our study showed that canine leishmania infection is prevalent with varying degrees in all the seven studied districts in Palestine despite the absence of human VL cases in 4 of these districts. The causative agent was confirmed to be Leishmania infantum. PMID:22937916

This study aimed to investigate the incidence and causes of home accidents in the West Bank and Gaza Strip of Palestine. Quantitative data were collected through a field survey of a random sample of 1882 people from the West Bank and Gaza Strip, and qualitative data through 15 focus groups discussions with men and women from diverse sectors of Palestinian society, which contributed to the interpretation of some of the results more deeply. The most important result from the study was that more women's were exposed to home accidents (40.0%) than men (25.1%). The most common type of accident for both women and men was from a blunt or sharp object casing blunt trauma or puncture wound. Economic situation of the family, family size, presence of children and place of residence were significantly associated with exposure to domestic accidents. There is a need to educate the people of Palestine on the causes of home accidents and methods of prevention, to reduce it incidence.
As part of the first anthropological study on suicide in the modern Arab world, statistics gathered from the Ramallah region of the West Bank in Palestine painted an apparently remarkably similar picture to that found in Western countries such as the UK and France. More men than women completed suicide, more women than men attempted suicide. Men used more violent methods such as hanging and women softer methods such as medication overdose. Completed suicide was higher in the older age range, attempted suicide in the younger. However, ethnographic fieldwork and detailed examination of the case studies and suicide narratives gathered and analysed within the cultural, political and economic contexts illustrated more starkly the differences in suicidal practices between Palestinian West Bank society of the 1990s and other regions of the world. The central argument of the paper is that although statistics tell a very important story, ethnography uncovers a multitude of stories 'behind the statistics', and thus helps us to make sense of both cultural context and subjective experience.

Background. Labor related injuries among Palestinian schoolchildren are a significant undocumented public health concern. This study aimed at documenting the prevalence and nature of work related injuries among schoolchildren as well as identifying sociodemographic factors that predict these injuries. Methods. A cross-sectional survey included 15,963 children of whom 6458 (40.8%) completed an optional package related to labor. Students aged 12–18 years self-completed the international WHO collaborative HBSC valid questionnaires between April and May of 2006. Results. Approximately 73.8% of the students who filled the optional package reported working during the last 12 months, of whom 79.1% sustained a work related injury. Work injuries were significantly higher among boys, younger children, and children enrolled in UNRWA schools and living in Gaza Strip (P < 0.05). Children working ≥3 hours/day were more likely to experience injuries, 1.73 (95% CI, 1.53–1.95), than those working ≤3/day. About half of the children worked in retail trade (51.5%), agriculture (20.0%), and cleaning (11.4%). Injury type was related to the type of work performed. Conclusions. The high prevalence of injuries among working Palestinian schoolchildren confirms its severity as a public health problem. To reduce occupational injuries, policymakers and professionals should develop intervention programs that target the public and health providers. PMID:25006490

Hydatidosis or echinococcosisis considered a neglected zoonotic disease despite its high burden in the livestock industry and the high risk of infection by humans in endemic areas. In a cross-sectional study we estimated the copro-Incidence and also genotyped Echinococcus granulosus isolates from domestic dogs using polymerase chain reaction (PCR). Medical archives in nine major hospitals in Palestine were reviewed to determine incidence of E. granulosus infection detected in humans during surgery. Faecal samples were collected from 93 domestic dogs in three districts with the highest number of human cases: Al-Khalil (Hebron), Tubas and Jenin. Genomic DNA was extracted from dog faecal samples and amplified by PCR targeting the repeat DNA sequence (EgG1 Hae III) followed by sequencing of five positive samples. Genotyping was determined by sequencing and BLAST searching of mitochondrial cytochrome c oxidase subunit (CO1). The incidence of E. granulosus infection detected in humans at surgery was 1.2 per 100,000 in the West Bank and 1.0 per 100,000 in Gaza Strip. Seventeen of 93 domestic dogs (18%) were positive, based upon comparison with the Echinococcus DNA control. The five sequenced samples were confirmed to be E. granulosus. Successfully genotyped sample belonged to E.granulosus sensu stricto (formerly G1-G3 complex, sheep strain). For domestic dogs, age group (13-24 months) and sex were identified as two risk factors for contracting E. granulosus. The study identified the high incidence of E. granulosus sensu stricto in dogs in Palestine.
Discourses and practices surrounding humanitarian organisations have changed over time. This is certainly the case for Palestinian non-governmental organisations, which have followed the structural and ideological transformations observed in local, regional and international contexts. There have been three successive but interlocking generations of groups active in health in Palestine: charitable societies, popular committees, and donor-based entities. Against this background, a village clinic in the West Bank is seen to have gone through various incarnations in the context of an emerging neo-liberal economic, administrative and political environment. Despite the critiques justifiably addressed towards them, non-governmental organisations may in some cases be functionally fluid. Communities and people continue to use them strategically in their relations with states, political groups, individuals and receivers of aid, making them potential networking sites in the context of an ongoing occupation.
The first modern dental institutes were established in Europe and in the USA during the 1840s. At that period there wasn't a single qualified doctor in Palestine, not to mention a professional dentist. A couple of decades later, as the number of Christian pilgrims grew, some modern hospitals were established and a few non-Jewish dentists opened their clinics in Jerusalem, which was then and in the following decades, the region's largest city. In Europe, dentistry became a popular profession among Jews in general and among Jewish women in particular. The first Jewish dentist settled in Jerusalem in the mid-1880s. Other dentists were slow to arrive and their number began to grow only after the turn of the 20th century. Their professional education varied from those who were trained as apprentices by other dentists to those which studied a couple of years in an academic dental school. The devastation caused by WWI prompted American-Zionist organizations to send a special medical unit to Palestine in 1918. Along medical supplies it also brought a small group of doctors and dentists. The two American dentists that decided to remain in Palestine took upon themselves to spread their medical and scientific knowledge. They also organized the dentists, whose number grew considerably during the 1920s, and called the authorities to regulate the dental profession. In 1926 the British authorities issued a decree regulating all medical professions. It demanded that dental practitioners will be licensed after proving their previous studies and professional knowledge. In 1931, local dentists' organizations decided to establish the Palestine Dental Association. Five years later it was accepted as a member by the International Dental Federation (FDI) and was recognized by the local authorities. Since the 1930s, prominent Jewish dentists from abroad were invited to come to Palestine to lecture, and local dentists participated in international conferences. This prompted the first

This study evaluated the effectiveness and usefulness of vaccination against diphtheria and tetanus in different age groups in Gaza, Palestine. Blood samples were collected from 180 children aged <12 years, 90 males and 90 females. Using ELISA methods, the efficacy of vaccination was estimated at 87.8% for diphtheria and 98.3% for tetanus. Mean serum titres varied significantly by age group: for diphtheria 0.24 IU/mL at age 2-4 years, 0.63 IU/mL at 7-8 years and 0.46 IU/mL at 11-12 years, and for tetanus 1.01 IU/mL, 2.63 IU/mL and 1.20 IU/mL respectively. The relatively low antibody titres, especially for diphtheria, suggest the need for a booster dose.

Occult hepatitis B infection is the case with undetectable HBsAg, but positive for HBV DNA in liver tissue and/or serum. Occult hepatitis B infection among hemodialysis patients in Palestine has been understudied. In this study, 148 hemodialysis patients from 2 northern districts in Palestine, Jenin (89) and Tulkarem (59), were investigated for occult hepatitis B, HBV, HCV infections with related risk factors. ELISA and PCR were used for the detection of anti-HBc and viral DNA, respectively. The overall prevalence of occult hepatitis B infection among the study group was 12.5% (16/128). Occult hepatitis B infection is more prevalent among males with most cases (15/16) from Jenin District. About one-third (42/132) of the hemodialysis patients were anti-HBc positive. Approximately 27% of the hemodialysis patients were infected with HCV. Around 20% (28/140) were positive for HBV DNA, but only 8.2% (12/146) of the hemodialysis patients were positive for HBsAg. The comparison between hemodialysis patients with occult hepatitis B infection and those without occult hepatitis B infection for selected risk factors and parameters as liver Enzyme, age, sex, HCV infection, blood transfusion, kidney transplant, anti-HBc, and vaccination showed no statistical significance between both categories. Duration of hemodialysis significantly affected the rate of HCV infection. HCV is significantly higher in hemodialysis patients with both Diabetes mellitus and hypertension. The prevalence of occult hepatitis B infection among hemodialysis patients is high; requiring stringent control policies. HBsAg assay is insufficient test for accurate diagnosis of HBV infection among hemodialysis patients.

It has often been stated that the Arab "world" is faced by a demographic challenge which is very different to that of many countries in the global North. As the Arab Spring has shown, youths across the region of the Middle East and North Africa (MENA) are keen to make a mark, and despite the internal conflicts and contests for power and influence, many young leaders are hoping to establish new forms of social cohesion which could lead to peace and prosperity within a globalised, interconnected world. This paper focuses on one aspect of the relationship between Arab youth and society, namely the difficult transition between formal education and employment. Drawing on, among other sources, a comparative study carried out across eight Arab states, the role which career education and guidance can play in the process is examined. This is followed by a case study of Palestine where, despite very challenging and difficult political and economic circumstances, significant and promising efforts have been made to help young people develop the life skills needed to engage with schooling in ways that do not only enhance learning, but also facilitate access to work and to self-employment. The paper argues that while career education and guidance (CEG) cannot possibly be expected to solve the disconnect between education and work, it does have a role to play in enhancing learning, in supporting transitions, and thus in contributing to both social and economic development goals.

A case-mix hospital information system was designed and implemented in Palestine Red Crescent Society hospitals in order to support the network of Palestinian hospitals in Lebanon and to improve the health of refugees in the country. The system is based on routine collection of essential administrative and clinical data for each episode of hospitalization, relying on internationally accepted diagnostic codes. It is a computerized, user-friendly information system that is a stepping-stone towards better hospital management and evaluation of quality of care. It is also a useful model for the development of hospital information systems in Lebanon and in the Near East.
In 1933, after the Nazi takeover in Germany, Eitingon decided to settle in Palestine. His ten Jerusalem years highlight a multifaceted personality that does not quite correspond to his usual image as a "grey eminence" of the international psychoanalytic movement: enthusiastic, vivid, highly involved in various--artistic, scientific, academic, social and pedagogic--acitivities of zionism in Palestine. In contrast, his last years were overshadowed by illness, financial ruin und the tragedies of war. Eitingon played a major role in the establishment of psychoanalysis in Palestine. However, the omnipresence of his name, associated with a purely Berlin psychoanalytic tradition, tends to obscure the important contributions of representatives of the Viennese tradition and the significant achievement of Moshe Wulff who was the real pioneer of psychoanalysis in Israel.

The main objective of this study was to assess Radon concentration in the harvested rainwater (HRW) at the household level in Yatta area, Palestine. HRW is mainly used for drinking as it is the major source of water for domestic uses due to water scarcity. Ninety HRW samples from the household cisterns were collected from six localities (a town and five villages) and Radon concentrations were measured. The samples were randomly collected from different households to represent the Yatta area. Fifteen samples were collected from each locality at the same day. RAD7 device was used for analysis and each sample was measured in duplicate. Radon concentrations ranged from 0.037 to 0.26 Bq/L with a mean ± standard deviation of 0.14 ± 0.06 Bq/L. The estimated annual effective radiation doses for babies, children and adults were all far below the maximum limit of 5 mSvy(-1) set by the National Council on Radiation Protection and Measurements.

The selection of an ambush-cum-foraging site and proper prey are indispensable for maintaining an adequate energy intake by sit-and-wait predators to optimize survival and future fitness. This is important for snakes, where an ambush site has suitable ambience. We studied the foraging strategy of the Palestine Saw-scaled Viper (Echis coloratus) at an avian migratory stopover site. Following initial observations, we hypothesized that vipers are able to discern the body mass of a perched bird and hunt accordingly. We implemented an experiment where vipers chose between four groups of migratory Blackcaps with different body mass. Prey choice by vipers of both age classes was not random and adults focused on Blackcaps with the lightest body mass. Juveniles displayed a variability of prey choice but selected mainly birds from the lightest categories. We concluded that Saw-scaled Vipers hunt prey based on thermal cues; juveniles practice on different prey groups prior to perfecting their foraging techniques i.e., hunting is a learned process; and that they prefer birds with the lowest body mass. The last because Blackcaps, when on migration, save energy by entering a state of deep torpor in which they sacrifice their vigilance capabilities.

Cutaneous leishmaniases (CL) are vector-borne parasitic diseases endemic in many countries of the Middle East including Palestine. Between 1994 and 2015, 2160 clinically suspected human cases of CL from the Jericho District were examined. Stained skin tissue smears and aspirates were checked by microscopy and cultured for promastigotes, respectively. For leishmanial species identification, amplification products from a PCR-ITS1 followed by RFLP analysis using Hae III. Data were analyzed using Epi Info free-software. The overall infection rate was 41.4% (895/2160), 56.3% (504/895) of the cases were male, 43.7% (391/895) female, 60.5% (514/849) children under age 14, 41.3% (259/627) of the cases were caused by Leishmaniamajor and 57.3% (359/627) by Leishmaniatropica. The case numbers peaked in 1995, 2001, 2004, and 2012. Statistically-significant clusters of cases caused by L. major were restricted to the Jericho District; those caused by L. tropica were from the districts of Jericho, Bethlehem, Nablus and Tubas. CL is seasonal and trails the sand fly season. Distribution of cases was parabolic with fewest in July. The monthly total number of cases of CL and just those caused by L. major correlated significantly with temperature, rainfall, relative humidity, evaporation, wind speed and sunshine (P<0.05, r(2)=0.7-0.9 and P<0.05, r(2)=0.5-0.8, respectively). Cases caused by L. tropica, significantly, had a single lesion compared to cases caused by L. major (P=0.0001), which, significantly, had multiple lesions (P=0.0001). This and previous studies showed that CL is present in all Palestinian districts. The surveillance of CL has increased public awareness and molecular biological methodology for leishmanial species identification is an essential addition to classical diagnosis. The overall results are discussed, correlated to climatic and environmental changes and large-scale human activities.

Dogs serve as hosts for a great number of parasites, which may affect their health and wellbeing. This study aimed to observe tick borne pathogens in dogs from Palestine including Hepatozoon canis and Babesia species. The prevalence of both H. canis and Babesia species infections in apparently healthy dogs, from ten districts of the West Bank was surveyed. DNA was extracted from blood samples obtained from dogs (n = 362) and ticks (n = 213) collected from dogs (n = 77). A primer set that amplifies a partial sequence of the Babesia and Hepatozoon 18S rRNA gene was used for PCR and the DNA sequences of the PCR products of all samples were determined. Twenty-nine (8·0%) of the dogs were found infected including 20 with H. canis (5·5%), seven with Babesia vogeli (1·9%) and two with undefined Babesia spp. (0·6%). Twelve Rhipicephalus sanguineus s.l ticks were pathogen-positive, including ten with H. canis (4·7%), one with B. vogeli (0·5%), and one with Hepatozoon felis (0·5%). The results indicated that a wide range of tick borne pathogens is circulating in the canine population in the surveyed region. This study is the first report on the prevalence of H. canis, B. vogeli and Babesia spp. in dogs in Palestine and its results will assist in the management of diseases associated with these blood parasites.

In nectarivorous birds, specialization for feeding on nectar has led to a simple gut structure with high sugar digestive efficiencies and rapid gut passage rates. These features of the digestive system may make digestion of more complex, protein-rich food sources, such as pollen or insects, less efficient. In this light, we hypothesized that sugar metabolizability in nectarivorous Palestine sunbirds (Nectarinia osea) would be high, whereas nitrogen metabolizability would be lower than typically found for birds. We measured glucose and fructose apparent metabolizabilities (*MCs) and transit times (TTs) in eight Palestine sunbirds offered either a 10% or a 50% mixed sugar diet. *MC for glucose (99.9%+/-0.1%) was significantly greater than for fructose (99.6%+/-0.4%; ANOVA; P<0.001). TT for the 10% sugar diet (26.3+/-10.1 min) was significantly shorter than for the 50% sugar diet (47.0+/-7.8 min). We measured nitrogen true metabolizability (MC) and TT in Palestine sunbirds offered a daily fruit fly intake of either 40 or 200 flies. Nitrogen MC was not significantly different between diets, and average MC for both diets was 58.5%+/-8.5% (n=8). TT was not significantly different when birds ate 10 flies (50.1+/-13.6 min) than when they ate 50 flies (48.5+/-16.5 min). The high sugar *MC and relatively rapid TT of nectar in Palestine sunbirds are similar to those found for other nectarivorous species. Transit times of insect material are longer that those found in small insectivorous species. However, MCs of insect material are lower. Thus, even though sunbirds consume easily digestible soft-bodied insects, they are less efficient at extracting protein than nonnectarivores.

Background Human enteroviruses (HEVs) are the most frequently reported cause of aseptic meningitis with or without CSF pleocytosis in childhood. Rapid detection and genotype of HEVs is essential to determine the causative agent and variant causing sepsis-like illness and/or aseptic meningitis. Aim To investigate the molecular epidemiology of enteroviruses (EVs) among patients with sepsis-like illness and/or aseptic meningitis admitted to three major hospitals in West Bank, Palestine from 2012 to 2015. Methods During the study period, 356 CSF samples were collected from patients with sepsis-like illness and/or aseptic meningitis. Two RT-nested PCR assays targeting a partial part of 5'UTR for direct diagnosis and the VP1 region for genotyping by sequence analysis of the viral genome were used. Results HEV RNA was detected in 66 of 356 (18.5%) of CSF samples. Age distribution showed that 64% (42/66) were infants (<1 year), 18% were children between 1 and 5 years old, 12% were children between 5 and 10 years old, and 6% were more than 10 years old. Of the 66 EV cases, 12 were successfully genotyped. Five different EV genotypes were identified. All of them belonged to HEV-B species. The study showed that echovirus 6 genotype accounted for 42% of the sequenced cases. The HEV infections in the present study tended to show slight seasonal pattern with more cases occurring during spring and summer, yet still significant numbers were also reported in fall and winter seasons. Conclusion HEV was isolated from a significant number of children with sepsis-like illness and/or aseptic meningitis. In addition, the molecular method utilized for direct diagnosis and genotyping of HEV from CSF revealed that more than one HEV type circulated in the West Bank, Palestine during the study period.

This article describes case study research for nursing and healthcare practice. Case study research offers the researcher an approach by which a phenomenon can be investigated from multiple perspectives within a bounded context, allowing the researcher to provide a 'thick' description of the phenomenon. Although case study research is a flexible approach for the investigation of complex nursing and healthcare issues, it has methodological challenges, often associated with the multiple methods used in individual studies. These are explored through examples of case study research carried out in practice and education settings. An overview of what constitutes 'good' case study research is proposed.

Sickle cell disease is an inherited autosomal recessive disorder of the beta-globin chain. In Palestine it is accompanied by a low level of Hb F (mean 5.14%) and a severe clinical presentation. In this study, 59 Palestinian patients, homozygotes for Hb S were studied for their haplotype background. Eight polymorphic sites in the beta-globin gene cluster were examined. The Benin haplotype was predominant with a frequency of 88.1%, followed by a frequency of 5.1% for the Bantu haplotype. One chromosome was found to carry the Cameroon haplotype (0.85%). Three atypical haplotypes were also found (5.95%). Heterogeneity was observed in Hb F production, ranging between 1.5 and 17.0%, whereas the (G)gamma ratio was homogeneous among all haplotypes with a normal amount of about 41%. Our results are in agreement with previous reports of the Benin haplotype origin in the Mediterranean.

Guidelines for the care of patients with diabetes mellitus are believed to improve clinical practice and patient care. This study aimed to analyse the pattern of diabetes care by physicians and nurses in primary care clinics in Palestine and their self-reported compliance with the local Palestinian guidelines. Questionnaires were used to collect data from 401 participants in 3 governorates in the West Bank. In total, 46.0% of participants knew about the existence of the Palestinian guidelines and about 60% believed these were partially used; 32.7% had received training on implementation of the guidelines. Multivariate analysis showed that training on the guidelines was the only factor significantly associated with self-reported compliance with guideline use. Respondents reported high commitment to the use of the guidelines, but their attitudes and behaviour varied with time constraints, availability of the guidelines, availability of laboratory tests and training on how to apply the guidelines.
Case studies and case reports form an important and ever growing part of scientific and scholarly literature. The paper deals with the share and citation rate of these publication types on different fields of research. In general, evidence seems to support the opinion that an excessive number of such publications may negatively influence the impact factor of the journal. In the literature of scientometrics, case studies (at least the presence of the term "case study" in the titles of the papers) have a moderate share, but their citation rate is practically equal to that of other publication types.

Rainwater samples harvested for drinking from the west part of Hebron (south of West Bank in Palestine), the largest city in the West Bank, were analyzed for the content of different trace heavy metals (Cr, Mn, Co, Ni, Cu, Zn, Mo, Ag, Cd, Bi, and Pb) by inductively coupled plasma mass spectrometry (ICP-MS). This study was conducted to determine the water quality of harvested rainwater used for drinking of south West Bank (case study, Hebron area). A total of 44 water samples were collected in November 2012 from 44 house cisterns used to collect rainwater from the roofs of houses. The samples were analyzed for their pH, temperature, electrical conductivity, total dissolved solids, and different heavy metal contents. The pH of all water samples was within the US Environmental Protection Agency limits (6.5-8.5), while some water samples were found to exceed the allowed WHO limit for total dissolved solids (TDSs) in drinking water. Results showed that concentrations of the heavy metals vary significantly between the 44 samples. Results also showed that the concentration of five heavy metals (Cr, Mn, Ni, Ag, and Pb) is higher than the WHO limits for these heavy metals in drinking water. Overall, our findings revealed that harvested rainwater used for drinking of this part of south West Bank is contaminated with heavy metals that might affect human health.

Water resources in the Middle East, particularly in Palestine, are extremely scarce and costly. The Jordan Valley is a fertile productive region, described as the food basket of Palestine. Groundwater originating from the Quaternary Aquifer System forms the main water resource in the Jordan Valley. However, the quality of this groundwater is threatened mainly by the high chloride concentration. The most representative area of the Jordan Valley is Jericho area, which was chosen to be the study area. The study area (65 km2) is almost a flat area with a gentle decline towards the east. It is the lowest land on earth with ground levels reaching 400 meters below sea level (mbsl) near the Dead Sea shores. The Quaternary Aquifer System in the study area could be divided into an upper alluvial layer with thickness varying from 40 to 150 m and a lower low-permeable Lisan layer, which crops out in the eastern part of the study area with thickness over 200 m. Hydrogeochemical investigation reveals that the water is generally earth alkaline with higher content of earth alkalis and prevailing chloride. According to Stuyfzand (1986) and Piper's (1944) classification systems, water type in the Alluvial Aquifer varies from fresh hard CaMgHCO3 or MgCaHCO3 water in the west and northwest to brackish very-hard MgNaCl or NaMgCl in the middle. In the east, the water becomes brackish-salt extremely-hard MgNaCl or NaCl. Groundwater quality is deteriorating (increase in salinity) spatially towards the east and vertically with increasing depth (when nearing the Lisan Formation). As an indication of groundwater salinity, total dissolved solids show some variability with time over the last 21 years (1983-2004). In short-time scale, there are high seasonal and yearly fluctuations with regard to salinity, specifically in Cl- and SO42- contents. Spring water from the Upper Cenomanian Aquifer (CaHCO3) represents the fresh end member, while Rift Valley Brines (RVB-CaNaCl) and Dead Sea Brines (DSB

Introduction Anti sperm antibodies (ASA) can present in serum and semen and they may lead to impair the sperms function leading to infertility. The precise mechanism of generation of these antibodies is yet to be discovered. Aim This study was performed to determine the prevalence of anti-sperm antibodies (ASA) in patients with unexplained infertility. The study was initiated also to explore the possible factors that may associate with ASA formation and how ASA status is associated with pregnancy rates after going with in vitro fertilization – intracytoplasmic sperm injection (IVF-ICSI). Materials and Methods A cross-sectional study was conducted on 42 normal infertile couples consulting Razan Medical Center for Infertility & I.V.F. in Nablus, Palestine, from December 2012 – March 2013. Serum levels of immunoglobulins G (IgG) ASA were measured in participants (males and females) using enzyme-linked immunosorbent assay (ELISA). In addition, participants also filled a questionnaire about the presence of previous varicocele repair, inguinal hernia repair, orchitis, testicular trauma and vasectomy reversal among males and severe coitus bleeding and coitus during menses or puerperium among females. Couples were also asked about previous IVF-ICSI procedures and the outcome of the procedure in terms of either they got pregnant or not. Data was analysed using SPSS software. Results The prevalence of ASA was 14.3% (6/42) among all couples, 9.5% (4/42) among males and 4.8% (2/42) among females. There was no significant relationship between previous varicocele repair, previous inguinal hernia repair, or orchitis and formation of ASA (p value =0.64, 0.56, and 0.26 respectively). Previous trauma, vasovasostomy, severe coitus bleeding and coitus during menses or puerperium were not observed in any of the study sample. ASA did not seem to affect the outcome of IVF-ICSI (p-value =0.54). Conclusion Prevalence of ASA in infertile couples in the north part of Palestine is similar

Natural plants products are one of the famous and commonly utilized remedies used in fighting diseases. This study was conducted to evaluate antioxidant activity of plants commonly used in Palestine (Urtica urens, Rumex cyprius and Borago officinalis). Free radical scavenging activity method was evaluated by using 2,2-diphenyl-1-picryl-hydrazyl-hydrate. The result show that the overall antioxidant activity of Rumex cyprius was the highest among the plants, followed by Urtica urens, and Borago officinalis; respectively. The (IC(50)) values of the methanolic extracts were 29.70±0.60μg/ml, 5.07±0.49μg/ml, 39.92± 0.52 μg/ml for Urtica urens, Rumex cyprius and Borago officinalis respectively. The results of this study revealed that these edible plants have high antioxidant activity and therefore they can provide natural sources of antioxidants and can be useful in preventing various diseases including cancer. These exhibited properties propose that such plants extracts can possibly be used as natural preservatives in the food and pharmaceutical industries and further characterization of Rumex cyprius constituents is needed.

NASA's Office of Exploration has undertaken four case studies for prospective expansion of manned space activities beyond earth orbit. The subjects of these studies are (1) an expedition to the Martian moon Phobos; (2) a three-mission expedition to Mars; (3) the construction of a man-tended lunar observatory; and (4) the construction of a lunar outpost to serve as the basis for construction of a Martian outpost. The fourth alternative would follow the recommendation of the National Commission on Space for the creation of a 'bridge between worlds' in which explorers would develop ways in which to 'live off the land' in a space environment.

Ticks play an important role in disease transmission as vectors for human and animal pathogens, including the Gram-negative pathogen Bartonella. Here, we evaluated the presence of Bartonella in ixodid ticks and domestic animals from Palestine. We tested 633 partly engorged ticks and 139 blood samples from domestic animals (dogs, sheep and camels) for Bartonella using ITS-PCR. Bartonella DNA was detected in 3.9% of the tested ticks. None of the ticks collected from sheep and goats were positive for Bartonella. Seventeen R. sanguineus ticks (17/391; 4.3%) collected from dogs were infected with B. rochalimae (n = 10), B. chomelii (n = 6), and B. koehlerae (n = 1). Four H. dromedarri ticks (4/63; 6.3%) obtained from camels were infected with B. bovis (n = 2) and B. rochalimae (n = 2). Among canine blood samples (n = 110), we found one asymptomatic female dog to be infected with B. rochalimae (0.9%). The detection of zoonotic Bartonella species in this study should raise awareness of these vector-borne diseases among physicians, veterinarians and public health workers and highlight the importance of surveillance and preventive measures in the region.

This work presents the results of exposure levels to radio frequency (RF) emission from different sources in the environment of the West Bank-Palestine. These RF emitters include FM and TV broadcasting stations and mobile phone base stations. Power densities were measured at 65 locations distributed over the West Bank area. These locations include mainly centres of the major cities. Also a 24 h activity level was investigated for a mobile phone base station to determine the maximum activity level for this kind of RF emitters. All measurements were conducted at a height of 1.7 m above ground level using hand held Narda SRM 3000 spectrum analyzer with isotropic antenna capable of collecting RF signals in the frequency band from 75 MHz to 3 GHz. The average value of power density resulted from FM radio broadcasting in all investigated locations was 0.148 μW cm(-2), from TV broadcasting was 0.007 μW cm(-2) and from mobile phone base station was 0.089 μW cm(-2). The maximum total exposure evaluated at any location was 3.86 μW cm(-2). The corresponding exposure quotient calculated for this site was 0.02. This value is well below unity indicating compliance with the International Commission on non-ionising Radiation protection guidelines. Contributions from all relevant RF sources to the total exposure were evaluated and found to be ~62 % from FM radio, 3 % for TV broadcasting and 35 % from mobile phone base stations. The average total exposure from all investigated RF sources was 0.37 μW cm(-2).

Delphi Automotive Systems and the Los Alamos National Laboratory worked together to develop PREDICT, a new methodology to characterize the reliability of a new product during its development program. Rather than conducting testing after hardware has been built, and developing statistical confidence bands around the results, this updating approach starts with an early reliability estimate characterized by large uncertainty, and then proceeds to reduce the uncertainty by folding in fresh information in a Bayesian framework. A considerable amount of knowledge is available at the beginning of a program in the form of expert judgment which helps to provide the initial estimate. This estimate is then continually updated as substantial and varied information becomes available during the course of the development program. This paper presents a case study of the application of PREDICT, with the objective of further describing the methodology. PREDICT has been honored with an R&D 100 Award presented by R&D Magazine.

Radon concentration and annual effective doses were measured in drinking water in the Southern Part of West Bank - Palestine, by using both passive and active techniques. 184 samples were collected from various sources i.e. tap water, groundwater, rain waters and mineral waters. It is found that the annual effective dose resulting from inhalation and ingestion of radon emanated from all types of drinking water is negligible compared to the total annual effective dose from indoor radon in the region. Results reveal that there is no significant public health risk from radon ingested and inhalation with drinking water in the study region.

In this article I posit and examine certain criteria and qualities for ending an analysis. The case study describes the end phase of a four-year psychoanalysis in which the patient's decision to move to another area forced the end of his analysis. We continued to explore and work through his core neurotic conflicts that included issues of competitive rivalry, dominance and submission, control, and anxiety about birth and death. A shift in the transference from me as a negative father to me as a supportive but competitive older brother was also examined in the context of ending treatment as well as other aspects of the transference. In addition, we analyzed the meaning of his ending treatment based on an extra-analytic circumstance. In discussing this phase of treatment, the definition and history of the term "termination" and its connotations are reviewed. Various criteria for completing an analysis are examined, and technical observations about this phase of treatment are investigated. It was found that while a significant shift in the transference occurred in this phase of the patient's analysis, conflicts related to the transference were not "resolved" in the classical sense. Terminating treatment was considered as a practical matter in which the patient's autonomy and sense of choice were respected and analyzed.

The need to notify individuals of a possible health risk from their past exposure to potentially hazardous agents frequently extends beyond workers to include community groups. The issues to consider in community notification are frequently similar to those that are important for worker notification but may include some that are unique. This case study traces the evolution of one company's strategy for communicating with the public about possible dioxin contamination associated with its operations. Early communications tended to emphasize the technical aspects of the issues in the fashion of scientists talking to other scientists. This was interpreted by some to be symptomatic of an arrogant and uncaring attitude. Beginning in the early 1980s, the company's management recognized the need to reach out to a variety of audiences on multiple levels, and shifted to a more comprehensive communications strategy. A similar shift is now occurring throughout the chemical manufacturing industry as top managers realize that, if they expect to continue to operate, they must become more accountable and responsive to the public.

Occupational hazards, exposure to blood and body fluids (BBF) accidents and safety precautions constitute an important public health issue. We assessed the prevalence and determinants of exposure to occupational hazards among nurses, and their knowledge of occupational safety precautions. In a cross-sectional study, we surveyed 332 nurses working in 4 hospitals, Nablus, West Bank, Palestine, by a questionnaire. Bivariate analysis tested the associations between ever exposure and the high likelihood of BBF exposure and the independent socio-demographic and occupational variables. Binary logistic regression analysis was used to assess the associations between the same two exposures and selected independent variables (those significant in the bivariate analysis). Prevalence of ever exposure to BBF was 51.7%, and was associated with working in private and charitable hospitals (OR 2.62, 2.68, respectively), having 4-6 family members (OR 0.52) and "nursing" being as one's top career choice at university (OR 0.48). The prevalence of high likelihood of BBF exposure was 62.2%, and was associated with working in charitable and private hospitals (OR 7.81, 2.43, respectively) and "nursing" being as one's top career choice (OR 0.57). Regarding knowledge, most respondents believed it is necessary to enact laws and regulations regarding occupational safety precautions, reported the use of sharps containers, immediate disinfection after an accident, reporting an accident, and using personal protective equipment. Nurses had adequate knowledge of the risks of their hospital work. Nevertheless, they exhibited high prevalence of exposure to BBF accidents. Future studies are needed to re-evaluate existing occupational safety guidelines in hospitals, establish monitoring and evaluation protocols for health care workers' adherence to the guidelines, and institute well-defined policies for reporting occupational injury incidents so these can be handled appropriately.
The trade-off between parents feeding themselves and their young is an important life history problem that can be considered in terms of optimal behavioral strategies. Recent studies on birds have tested how parents allocate the food between themselves and their young. Until now the effect of food consumption by parent birds on their food delivery to their young as well as other parental activities has rarely been studied. I have previously shown that parent Palestine sunbirds (Nectarinia osea) will consume nectar and liquidized arthropods from artificial feeders. However, they will only feed their young with whole arthropods. This provided a unique opportunity to experimentally manipulate the food eaten by parents independent of that fed to their offspring. Here, I hypothesized that parents invest in their current young according to the quality of food that they themselves consume. Breeding pairs with two or three nestlings were provided with feeders containing water (control), sucrose solution (0.75 mol) or liquidized mealworms mixed with sucrose solution (0.75 mol). As food quality in feeders increased (from water up to liquidized mealworms mixed with sucrose solution): 1) Parents (especially females) increased their food delivery of whole arthropod prey to their young. 2) Only males increased their nest guarding effort. Nestling food intake and growth rate increased with increasing food quality of parents and decreasing brood size. These results imply that increasing the nutrient content of foods consumed by parent sunbirds allow them to increase the rate at which other foods are delivered to their young and to increase the time spent on other parental care activities.

The geological, geomorphological and hydrological features along the course of the Wadi Gaza (Palestine) are discussed. The study confirms the existence of Pleistocene loess sediments along the Wadi. Wadi Gaza is characterized by meandering features along its course. The watershed of Wadi Gaza is estimated to cover more than 3500 km2 of the Northern Negev Desert and the Hebron Mountains as well as the small catchment sub-area in the Gaza Strip itself. Storm water drains the hills and mountains of Hebron and the northern Negev desert, accumulates in the Beer-Sheva area, crosses the Gaza Strip and discharges into the Mediterranean Sea. In winter the Wadi Gaza brings about 20 million cubic meter of rainwater into the area. Field investigations demonstrate the existence of loess sediments in the Wadi Gaza area, deposited during the dry periods that affected the area during the Pleistocene. The Digital Elevation Model (DEM) applied for the Gaza Strip confirmed the existence of three Kurkar ridges within the Gaza Strip. Arranged from west to east (i) Sheikh Ejlin Ridge extends up to the current coastline in the west, (ii) Al Montar Ridge occurs near the armistice line in the east and (iii) Bait Hanon Ridge of which a part is present to the northeast of the Gaza Strip and a part to the east of the armistice line (the intermediate part not being accessible for observation due to political reasons. It is considered as a security zone). All three ridges are running NE-SW, parallel to the Mediterranean coastline.

We present the case of a 26 year old Indian base worker who attended the Role 2 enhanced hospital in Iraq with a case of leprosy. The patient presented four times over a 12 month period with non-specific pain in the right hand and forearm combined with a large lesion of dry skin and reduced sensation in the forearm. A clinical diagnosis of leprosy was made, which was subsequently confirmed as paucibacillary leprosy by skin smears sent to the UK. It was not possible to treat the patient locally and a recommendation made to the patient's employer that the patient return to India to commence treatment.

Walter Henry Anderson, a brewer's clerk in Burton-upon-Trent, became a missionary doctor, supported by a society promoting welfare and evangelism in Jewish communities abroad. His family background was rich in pastoral ministry at home and adventure abroad. Arguably, this background played a part in his decision to serve the Jews of Safed. His life in Palestine entailed much enterprise and hardship as he raised a family, fought disease and set up a mission hospital serving not only the Jewish community but persons of all faiths. His years in Palestine, from 1894 to 1915, were times of peace in the Middle East before the turmoil unleashed by the Great War. Jews from the Diaspora were gaining an increasing foothold in Palestine, their 'Promised Land'. Themes of that era - the rise of Zionism, confrontation between Judaism and evangelical Christianity, conflict between immigrant Jew and Palestinian Arab and the remarkable travels of Lawrence of Arabia were interwoven with the lives of Dr Anderson and his family.

The objective of this volume of contributed chapters is to present a series of applications of geostatistics. These range from a careful variographic analysis on uranium data, through detailed studies on geologically complex deposits, right up to the latest nonlinear methods applied to deposits with highly skewed data contributions. Applications of new techniques such as the external drift method for combining well data with seismic information have also been included. The volume emphasizes geostatistics in practice. Notation has been kept to a minimum and mathematical details have been relegated to annexes.
Everyone in science should have ethics education training. I have seen graduate students taken advantage of by their mentors. Many of us have seen misconduct...but what should we do about it? Young scientists are often unaware of the rules in science and make mistakes because of their ignorance of the rules in that particular field of study. Then there are an increasing number of cases in the news of overt cases of misrepresentation in science. All are welcome to attend this discussion of case studies. A case study on topics such as: how to treat data properly, how our values in science affect our work, who gets authorship on scientific papers, who is first author on a paper, what you should do if you uncover misconduct or plagiarism in your university, and we will discuss the scientist's role in society. This will be a painless, non-confrontational small group, then large group discussion of each case

Breaking the students into small, collaborative learning groups to solve a meaningful task together is one of the most successful and fully evaluated teaching techniques implemented over the last century. Although there are many ways to accomplish small group learning, a long-standing and consistently successful collaborative class activity is to use the case study teaching strategy. The use of case studies is common in medical schools and law schools, but not so common in the teaching of astronomy. Case studies create meaningful conversations among students and with the professor by focusing on life-like dilemmas to be solved. Case study tasks ask audience members to synthesize several ideas or evaluate scenarios that have not been explicitly presented to them in the lecture or in available readings.

On 21st November 1916, the Royal Navy Hospital ship 'Britannic' (the sister ship of the 'Titanic') was torpedoed near the island of Kea in the Aegean Sea. Captain Dr. John Cropper, aged 52, was one of 30 people who drowned of the 1100 on board. Dr. Cropper was born in 1864, at Guisborough, England. He obtained his medical degree from Cambridge University in 1891. After his marriage to Anne Ellen Walker in 1895, the Church Missionary Society sent him on a medical mission to Palestine. Dr. Cropper stayed in Palestine for about 10 years working in Acre, Nablus, Ramallah and Jerusalem. He published his experiences in 35 articles and letters in English medical periodicals, more than anyone else did in Palestine at that time. In those publications, he described various operations that he carried out and observations on infectious diseases, most of which were the first descriptions from that remote and unhealthy country. His prominent research was in the field of malaria - the most common and important disease in Palestine during that period. It was less than two years after Grassi's discovery of the role of Anopheles mosquitoes as the vector of human malaria that Dr. Cropper carried out surveys of larval and adult mosquitoes in correlation with malarial distribution in Palestine. Dr. Cropper was the first who routinely examined slides microscopically in Palestine and correctly diagnosed the type of malaria. Dr. Cropper was also the first in Palestine to suggest antimalarial measures aimed directly at the mosquito vector and paid attention to ecological aspects such as breeding places and the daily behavior of adult mosquitoes. Dr. Cropper noted the common antimalarial measurements of that time, such as covering of wells, planting of Eucalyptus trees to drain swamps and the routine use of quinine as a preventive medicine, but he wrote that those measures were not effective under the local conditions. He suggested that the only effective measures must be aimed against the

Until now, neither phenotypic nor molecular approaches have been used to characterize the landraces of Palestine faba beans (Vicia faba). We used PCR-based RAPD markers to determine the genetic diversity and relatedness among 26 Palestinian faba bean landraces (traditional farmers' varieties) from 8 localities in the West Bank, Palestine. In tests with 37 primers, 14 generated no polymorphic bands, 12 exhibited weak and unclear products, and 11 primers produced good amplification products with high intensity and pattern stability. Ninety-four DNA fragments (loci) were detected, with an average of 8.54 loci per primer and size ranging from 160 to 1370 bp. A minimum of 4 and a maximum of 14 DNA fragments were obtained using (OPA-05 and OPA-09) and (BC-261) primers, respectively. The maximum percentage of polymorphic markers was 71.4 (BC-298) and the minimum was 50.0 (OPA-05, -09, -16). The 11 primers exhibited relatively high collective resolving power (Rp) values of 26.316, and varied from 0.154 for the OPA-09 primer to 5.236 for the BC-261, with an overall mean of 2.392. The primers BC-261, -322, and -298 were found to be the most useful RAPD primers to assess the genetic diversity of Palestinian faba beans, as they revealed relatively high Rp rates (5.236, 3.618, and 3.150, respectively). Based on the Jaccard coefficient, the genetic distance ranged from 0.358 to 0.069, with a mean of 0.213. We conclude that the RAPD technique is useful for determining genetic diversity and for developing suitable fingerprints for faba bean landraces grown in Palestine.

Draft genome sequencing of Pm-OXA-48 identified 16 antimicrobial resistance genes, encoding resistance to β-lactams, aminoglycosides, fluoroquinolones, phenicols, streptothricin, tetracycline, and trimethoprim-sulfamethoxazole. Complete sequencing of the bla(OXA-48)-harboring plasmid revealed that it is a 72 kb long IncL/M plasmid, harboring carbapenemase gene bla(OXA-48), extended spectrum β-lactamase gene bla(CTX-M-14), and aminoglycoside resistance genes strA, strB, and aph(3')-VIb.

This study presents the seasonal variations of indoor radon levels in dwellings located in the Ramallah province and East Jerusalem suburbs, Palestine. The measurements were performed during the summer and winter of the year 2006/2007 using CR-39 solid-state-nuclear-track detectors. The total number of investigated buildings is 75 in summer and 81 in winter. A total number of 142 dosemeters are installed in dwellings for each season for a period of almost 100 d. The radon concentration levels in summer varied from 43 to 192 Bq m(-3) for buildings in the Ramallah province and from 30 to 655 Bq m(-3) for East Jerusalem suburbs. In winter, the radon concentration levels are found to vary from 38 to 375 Bq m(-3) in the Ramallah buildings and from 35 to 984 Bq m(-3) in East Jerusalem suburbs. The obtained results for radon concentration levels in most places are found to be within the accepted international levels.

Patterns of cognitive deficit in single neuropsychological cases are common sources of evidence for theories of normal cognition. In particular, the working memory model has benefited from data obtained from a number of contrasting patients, in some cases resulting in modifications of the working memory model. In this paper, patterns of data from short-term memory patients and anarthric patients are compared with patterns of data from normal subjects. The patterns of patient data that were unlike those patterns typically found for groups of normal subjects, could be incorporated within a modified version of the articulatory loop component of the working memory model. However a small number of individual normal subjects also did not show the pattern that is reported on the basis of average performance of groups of normal subjects. This causes some difficulty in interpreting those data from such 'aberrant normal' patterns, and those data from single patients with functional cognitive deficits. The implications of these findings for the interpretation of neuropsychological data are discussed in the context of the working memory model, but with the intention of making a general point pertaining to the development of functional models of cognition. It is argued that single case studies should continue to provide a useful source of evidence, providing that care is exercised in considering the implications of such data for models of normal cognition.

Until 1929, midwifery in Palestine was relatively open to anyone and only partially regulated by the 1918 Public Health Ordinance, legislated shortly after the beginning of British rule. This article describes the factors that guided the shaping of midwifery and suggests possible sources of inspiration for the British legislator in crafting the Midwives Ordinance in 1929, including American, local (Jews and Arabs), and British ones. The Midwives Ordinance reflects the adjustment of midwifery to changes in the society that evolved under the British Mandate. The ordinance shows how the modern midwife's role contracted relative to the traditional one, in the context of social processes in other countries, east and west. This historical research project is based on interviews, archive documents and research literature. It analyzes the British interests in regulating midwifery, including the rationale of preserving public health and reducing infant mortality, against a background of political power struggles as well as cultural, social and professional diversity in Palestine (the tensions between the powers of doctors, nurses, and pharmacists).

Safe handling of food in restaurants is a basic element in the reduction of foodborne illness. We investigated knowledge and practices about food safety by food-handlers in restaurants in Ramallah and Al-Bireh district of Palestine. A high proportion of workers in the restaurants had no previous experience in other restaurants and 63.4% had received no training on food sanitation and safety. Most of the restaurants in the refugee camps, villages and towns had only 1 worker. Restaurants lacked basic conditions for food sanitation and safety, such as hot water in most and cleaning materials in some. Many workers had poor personal hygiene practices. Training is needed for restaurant owners and staff to improve food handling practices and standards.

Ixodid ticks transmit various infectious agents that cause disease in humans and livestock worldwide. A cross-sectional survey on the presence of protozoan pathogens in ticks was carried out to assess the impact of tick-borne protozoa on domestic animals in Palestine. Ticks were collected from herds with sheep, goats and dogs in different geographic districts and their species were determined using morphological keys. The presence of piroplasms and Hepatozoon spp. was determined by PCR amplification of a 460-540bp fragment of the 18S rRNA gene followed by RFLP or DNA sequencing. A PCR-RFLP method based on the 18S rRNA was used in order to detect and to identify Hepatozoon, Babesia and Theileria spp. A total of 516 ticks were collected from animals in six Palestinian localities. Five tick species were found: Rhipicephalus sanguineus sensu lato, Rhipicephalus turanicus, Rhipicephalus bursa, Haemaphysalis parva and Haemaphysalis adleri. PCR-based analyses of the ticks revealed Theileria ovis (5.4%), Hepatozoon canis (4.3%), Babesia ovis (0.6%), and Babesia vogeli (0.4%). Theileria ovis was significantly associated with ticks from sheep and with R. turanicus ticks (p<0.01). H. canis was detected only in R. sanguineus s.l. and was significantly associated with ticks from dogs (p<0.01). To our knowledge, this is the first report describing the presence of these pathogens in ticks collected from Palestine. Communicating these findings with health and veterinary professionals will increase their awareness, and contribute to improved diagnosis and treatment of tick-borne diseases.

Atorvastatin reduces morbidity and mortality due to cardiovascular events. This study was conducted to assess the prices and pharmaceutical quality of innovator atorvastatin 20 mg with its locally available generics in Palestine and to assess the suitability of their interchangeability. The prices of innovator and generic atorvastatin 20 mg were determined and compared. Innovator atorvastatin and four generic products were tested for their pharmaceutical quality. Tablets were tested for their drug contents, weight uniformity, hardness, disintegration and dissolution. Three out of four generics were less expensive than the innovator. Pharmaceutical quality assessments were satisfactory and within limits for all atorvastatin tested products. The average weight ranged from 206.6 ± 8.40 to 330 ± 3.92 mg and the %RSDs were within the permitted limits as per USP. Tablet hardness ranged from 102 ± 1.41 to 197.4 ± 6.88 kg and drug contents ranged from 92.2% to 105.3%. All products disintegrated within permitted time limits and showed very rapid dissolution. Products released more than 85% of their drug contents in less than 15 min. Our results showed that all tested innovator and generic atorvastatin products were of good pharmaceutical quality. Despite the lack of in vivo evaluation, our results indicate that these products are equivalent in vitro. Considering the in vitro release characteristics, these products might be used interchangeably. However, regulatory authorities permit the use of in vitro data in establishing similarity between immediate release oral dosage forms containing biopharmaceutical classification system class I and III drugs only.

Acute limb ischemia is a complication of severe peripheral arterial disease that can be a threatening limb as well as life. Multiple procedures exist today to help revascularize extremities; however, even with the latest technologies, surgical amputation of the limb may still be necessary. Cryoamputation, or physiologic amputation, is a method used to treat patients who are hemodynamically unstable for the operating room and who are in need of urgent amputation owing to arterial ischemia. This procedure is used in the rare instance where not only a persons' limb is threatened, but also their life. This is a case study regarding one patient who presented to the hospital with limb-threatening ischemia who became hemodynamically unstable owing to the rhabdomyolysis associated with the ischemia of his lower extremity. Cryoamputation was used to stabilize the patient and prevent further deterioration, so that he could safely undergo surgical amputation of the limb without an increase in mortality risk. Cryoamputation must be followed by formal surgical amputation when the patient is hemodynamically stabilized. It is not a limb salvaging, procedure but it is a life-saving procedure. This case study demonstrates the usefulness of the procedure and discusses the technique used for cryoamputation.

Case studies can be useful in assessing and learning lessons from emergency situations. In this paper, different uses for disaster case studies, are explored with identification of potential pitfalls that should be avoided. In addition, ways to improve the rigor and significance of case studies are suggested. Case studies can be used as examples or as a research tool. If conducted properly, they can provide robust and compelling results. It is argued that sharing a common guide to conducting and writing case studies among all disaster risk reduction professionals could improve the quality of case study reports and thereby strengthen their value in advancing the prevention, preparedness, and management of disasters and emergencies.

The activity concentrations of naturally occurring radioactive materials such as (238)U, (232)Th and (40)K were measured for 38 soil samples collected from diverse zones in the southern area of West Bank, Palestine using gamma-ray spectroscopy. The measured activities of (238)U, (232)Th and (40)K were found to range from 32.9 to 104.7, 14.5 to 76.6 and 297 to 962 Bq kg(-1) with averages value of 68.7, 48.0 and 630 Bq kg(-1), respectively. The obtained values of activity concentrations are higher than the world average of 35, 30 and 500 Bq kg(-1) for (238)U, (232)Th and (40)K, respectively. The measured (137)Cs activity concentration was found to range from 1.8 to 36.1 Bq kg(-1) with an average value of 8.5 Bq kg(-1). The detected activities were attributed to the fallout of (137)Cs, which is the only man-made radionuclide. The calculated average of the total gamma-radiation dose rate of natural radionuclides, (137)Cs and cosmic radiation is 121.4 nGy h(-1). The radium equivalent activity (R(aeq)), dose rate (D(r)), external hazard index (H(ex)) and radioactivity level index (I(gamma)) in all samples are presented. Some values were found to be in the range of worldwide values, whereas others were above the worldwide values.

Currently in the United States, the heavy majority of plug-in electric vehicle (PEV) sales have been in highly conducive, selected, metropolitan areas; opposed to more broad distribution across the country. The U.S. Department of Energy’s EV Everywhere Grand Challenge is looking carefully at the barriers and opportunities that exist to enable small and midsize communities to partake in the PEV market and benefit from the economic and environmental advantages of PEVs. In order to gain insight into these challenges and barriers, DOE selected a success story (i.e., Drive Electric Vermont) as the subject of this case study, as the state of Vermont is tied with Detroit, Michigan in having the highest percentage of 2014 (most recent complete data) PEV registrations for cold weather U.S. cities and has seen more than a sixfold increase in charging stations over the last three years. The overall objective of this case study was to use the lessons learned from Drive Electric Vermont to determine what activities are most effective at encouraging acquisitions of PEVs and deployment of charging infrastructure in small to midsize communities, prioritizing and sequencing their implementation, identifying robust means for extrapolation, and applying this understanding to other small to midsize communities across the nation. The Drive Electric Vermont Program was formed in 2012 with a goal of increasing the use of electrified transportation in Vermont through policy development, education and outreach, and infrastructure development. The Drive Electric Vermont Program can be broadly broken into four components: (1) strategic planning/leadership, (2) stakeholder/partnership development, (3) education and outreach, and (4) incentives. The early phases of the program focused heavily on strategic planning, and stakeholder and partnership development, followed by a transition to education and outreach activities, charging infrastructure development, and grant and incentive programs

The urachus, or median umbilical ligament, is a midline tubular structure that extends upward from the anterior dome of the bladder toward, the umbilicus and represents the vestigial remnant of at least two embryonic structures, the cloaca and the allantois. The tubular urachus normally involutes before birth, remaining as a fibrous band, however its persistence can give rise to various clinical problems, not only in infants and children but also in adults. We report two cases of pyourachus at our institute with a review of the clinical presentation, imaging findings and surgical management. Both our patients were young males, with haematuria being the presenting feature in one case which has not been previously described in literature.

We report a case of massive associative visual agnosia. In the light of current theories of identification and semantic knowledge organization, a deficit involving both levels of structural description system and visual semantics must be assumed to explain the case. We suggest, in line with a previous case study, an alternative account in the framework of (non abstractive) episodic models of memory.

The research presented in this dissertation covers three separate topics of conservation as defined by the National Science Foundation: 1) Materials Stabilization, Strengthening, Monitoring, and Repair; 2. Understanding Material Degradation and Aging; and 3) Materials and Structural Characterization of Cultural Heritage Objects (the 'technical study'). The first topic is addressed through a study to assess the consolidant tetraethoxysilane for the stabilization of alum treated wood. Falling under materials degradation studies is a study published in American Museum Novitates to understand how environmental conditions affect the aging of fossil resins from five different deposits. Two separate studies are included in technical study of cultural heritage objects which comprises the third research area of materials characterization. The first is a survey of red dyes used in Chinese paintings from the Ming Dynasty to the Early Republic (1364-1911). The second is a study of the pigments, dyes and binders used in Hawaiian barkcloth (kapa) from the 19th century.

This paper proposes a new methodology to assess demand and price-elasticity for health care, based on patients' stated willingness to pay (WTP) values for certain aspects of health care quality improvements. A conceptual analysis of how respondents consider contingent valuation (CV) questions allowed us to specify a probability density function of stated WTP values, and consequently, to model a demand function for quality-improved health care, using a parametric survival approach. The model was empirically estimated using a CV study intended to assess patients' values for improving the quality of primary health care (PHC) services in Palestine. A random sample of 499 individuals was interviewed following medical consultation in four PHC centers. Quality was assessed using a multi-attribute approach; and respondents valued seven specific quality improvements using a decomposed valuation scenario and a payment card elicitation technique. Our results suggest an inelastic demand at low user fees levels, and when the price-increase is accompanied with substantial quality-improvements. Nevertheless, demand becomes more and more elastic if user fees continue to rise. On the other hand, patients' reactions to price-increase turn out to depend on their level of income. Our results can be used to design successful health care financing strategies that include a consideration of patients' preferences and financial capacities.

Multi-electrode geo-electrical and transient electromagnetic surveys were carried out to characterize the nature of the subsurface infiltration zones (5 to 20 m) related to a series of groundwater outlets, and to reveal the geometry of the different aquifers at Bani-Naim, in the south-eastern foothills of the Hebron area, West Bank, Palestine. The purpose of the surveys was to understand the link between water storage/transfer and the characteristics of the geological formations. The strata in this semi-arid region are composed of alternate layers of chalky limestone, hard limestone, marl and chalk. A total of 30 ERT and 15 TDEM were conducted at Bani Naim-Jahir and Bani Naim-Birein. A correlation between the results indicates various infiltration pathways: fractures, feature heterogeneities, and porous chalk. The local heterogeneity on the eastern side were the major pathways for the water infiltration, whereas the thick marl layer underneath acts as a natural impermeable barrier preventing water from infiltrating deeper. A combination of the different geophysical results identified conductive features that correspond to the infiltration zones supplying the dug wells with water. Furthermore, it was established that the fractured chalk and porous chalky limestone act as an aquifer. A three-dimensional visualization of the resistivity allowed a useful reconstruction of the shallow hydrogeological system. Consequently, these studies contribute to regional sustainable development projects in this semi-arid region.

Several features of the obesity epidemic in Africa mirror those in other emerging nations: it penetrates the richer nations and urban areas first with a strong urban- rural gradient; initially it affects the wealthy, but later there is a demographic switch as obesity becomes a condition more associated with poverty, and it shares many of the same drivers related to the increasing affordability of highly refined oils and carbohydrates, and a move away from subsistence farm work and towards sedentary lifestyles. Africa also has some characteristics of the obesity epidemic that stand out from other regions such as: (1) excepting some areas of the Pacific, Africa is probably the only region in which obesity (especially among women) is viewed culturally as a positive and desirable trait, leading to major gender differences in obesity rates in many countries; (2) most of Africa has very low rates of obesity in children, and to date African obesity is mostly an adult syndrome; (3) Africans seem genetically prone to higher rates of diabetes and hypertension in association with obesity than Caucasians, but seem to be relatively protected from dislipidemias; (4) the case-specific deaths and disabilities from diabetes and hypertension in Africa are very high due to the paucity of health services and the strain that the 'double burden' of disease places on health systems.

The multifamily case studies that are the subject of this report were conducted to provide a better understanding of the approach taken by program operators in weatherizing large buildings. Because of significant variations in building construction and energy systems across the country, five states were selected based on their high level of multifamily weatherization. This report summarizes findings from case studies conducted by multifamily weatherization operations in five cities. The case studies were conducted between January and November 1994. Each of the case studies involved extensive interviews with the staff of weatherization subgrantees conducting multifamily weatherization, the inspection of 4 to 12 buildings weatherized between 1991 and 1993, and the analysis of savings and costs. The case studies focused on innovative techniques which appear to work well.

It has been recently asserted that the nested case-control study design, in which case-control sets are sampled from cohort risk sets, can introduce bias (“study design bias”) when there are lagged exposures. The bases for this claim include a theoretic and an “empirical evaluation” argument. Both of these arguments are examined and found to be incorrect. Appropriate methods to explore the performance of nested case-control study designs, analysis methods, and compute power and sample size from an existing cohort are described. This empirical evaluation approach relies on simulating case-control outcomes from risk sets in the cohort from which the case-control study is to be performed. Because it is based on the underlying cohort structure, the empirical evaluation can provide an assessment that is tailored to the specific characteristics of the study under consideration. The methods are illustrated using samples from the Colorado Plateau uranium miners cohort. PMID:19289963

The aim of this study is to provide an overview of the scientific activity of different psychoanalytic schools of thought in terms of the content and production of case studies published on ISI Web of Knowledge. Between March 2013 and November 2013, we contacted all case study authors included in the online archive of psychoanalytic and psychodynamic case studies (www.singlecasearchive.com) to inquire about their psychoanalytic orientation during their work with the patient. The response rate for this study was 45%. It appears that the two oldest psychoanalytic schools, Object-relations psychoanalysis and Ego psychology or “Classical psychoanalysis” dominate the literature of published case studies. However, most authors stated that they feel attached to two or more psychoanalytic schools of thought. This confirms that the theoretical pluralism in psychoanalysis stretches to the field of single case studies. The single case studies of each psychoanalytic school are described separately in terms of methodology, patient, therapist, or treatment features. We conclude that published case studies features are fairly similar across different psychoanalytic schools. The results of this study are not representative of all psychoanalytic schools, as some do not publish their work in ISI ranked journals. PMID:26483725

Indoor radon level measurements were carried out in 42 dwellings in Bethlehem, Palestine, using CR-39 solid state nuclear track detectors. The measurements were performed during winter and spring seasons of the year 2010, for a period ranging from 97-118 d using a total of 100 detectors. The detectors were installed in living rooms, bedrooms, kitchens, and storage areas of 39 houses, as well as in three schools, selected randomly in the surveyed area. The results of indoor radon levels and the annual effective dose in houses were found to vary from 26 - 611 Bq m(-3) and 0.65 - 14.1 m Sv y(-1), with average values of 117.0 Bq m(-3) and 2.95 m Sv y(-1), respectively. The mean values of radon concentration levels in bedrooms, kitchens, living rooms, basements, and storage areas are, respectively, 106.5, 113.1, 101.5, and 164.2 Bq m(-3). The corresponding mean values of annual effective dose for the bedrooms, kitchens, living rooms, basements, and storage areas are 2.66, 2.83, 2.54, 14.1 m Sv y(-1), respectively. In schools, the radon levels are found to vary from 31 - 400 Bq m(-3) with an average value of 125.1 Bq m(-3). The average annual effective dose in schools is found to be 3.12 mSv y(-1). This value is higher than the assigned international value. In general, the results show that radon concentration levels in 83% of the investigated dwellings are lower than the indoor radon action level of 150 Bq m(-3) for the United States.

Background. Polyorchidism, alternatively supernumerary testes (SNT), is a condition where an individual is born with more than two testicles. This congenital anomaly is quite rare and the literature has described various presentations. Questions/Purposes. To our knowledge, this presentation of polyorchidism has yet to be described in the literature. The goal of this case study is to add to the pediatric, general, and urologic surgery's body of knowledge of the subject matter. Case Study. A nine-month-old boy was admitted for an impalpable right testis and phimosis. At the time of surgical exploration, there appeared to be polyorchid testis on the right-hand side, with three masses that potentially appeared to be undescended testes. Discussion. Proponents of a conservative approach argue that infertility is common in patients with polyorchidism and, by preserving a potentially functional SNT, there may be improved spermatogenesis. When performing definitive surgical treatment, meticulous intra-abdominal and intrainguinal exploration must be undertaken. Orchiopexy should be performed to reduce the chances of torsion, malignancy, and infertility. Conclusion. Our case is important to the literature as it is the first known case of polyorchidism with 3 SNT on the right side, located intra-abdominally, and in a patient less than 1 year of age. PMID:27722006
The value of case studies for theory building is still doubted in psychology. The paper argues for the importance of case studies and the possibility of generalizing from these for a specific sociocultural understanding of human development. The paper first clarifies the notion of abduction within case studies, drawing on pragmatists James and Peirce and expanding it with the work of Lewin, and argues that it is the core mechanism that allows generalization from case studies. The second section presents the possibility of generalizing from individual single case studies, for which not only the subjective perspective, but also the dynamics by which the social and cultural environment guide and enable the person's development, have to be accounted for. The third section elaborates the question of institutional case studies, where the challenge is to account both for institutional dynamics, and for persons' trajectories within; this is exemplified with an ongoing study on the process of obtaining citizenship in Switzerland. The paper briefly concludes by highlighting two possible implications of the paper, one concerning the process of theoretical reasoning, the other, the fact that sociocultural psychology could itself be seen as an institution in-the-making.

The cause of Moyamoya disease is still unknown. We made a research about the factors closely related to Moyamoya disease through a case-control study. The number of cases studied was 66. Controls were selected from among patients' friends, matched as to sex, age and residential area. Questionnaires were sent to the cases and the respective controls by mail. The questions were about past history, developmental history, school records, habitual factors, dietary habits and pets. The first symptoms and age at onset were also surveyed in the cases. The response rate was 84.8% (56 cases) of the cases and 76.5% (101 cases) out of the 132 controls. There was no significant difference in the prevalence of tonsillitis, conjunctivitis, otitis media, and bronchitis. Odds ratio of fever of unknown origin is 2.793 and X2 is 7.213. Diseases whose odds ratio was over 1 were herpes, appendicitis, bronchitis, asthma, anemia, dental caries, head injury and drug allergy. But all of them were not significantly prevalent. Odds ratios of school records were 4-9 and X2 were 4-17 from elementary to junior high school. Odds ratio of western dishes was 2.709 and X2 was 5.189. There was no significant difference as to pets kept. We could not find overt relationships between Moyamoya disease and diseases of head and neck like tonsillitis.

Through data collection methods using a holistic approach that focuses on variables in a natural setting, qualitative research methods seek to understand participants' perceptions and interpretations. Common qualitative research methods include ethnography, phenomenology, grounded theory, and historic research. Another type of methodology that has a similar qualitative approach is case study research, which seeks to understand a phenomenon or case from multiple perspectives within a given real-world context.

We present the first case study of idiopathic gigantic suprapubic lymphedema and buried penis treated with puboscrotal reconstruction in a patient with initial extreme obesity after an extensive weight reduction (120 kg). Massive localized lymphedema of the suprapubic region should be differentiated from the scrotal type. Severe lymphedema could not resolve on its own and weight reduction does not seem to be helpful in such cases. PMID:27574599

The vitreous of three patients with asteroïd hyalosis (average age: 57 years) was obtained by a two-hand closed pars plana vitrectomy. Asteroïd hyalosis was associated with alcoholic neuropathy in the first case, long standing retinal detachment in the second case, and diabetes mellitus in the third case. The visual acuity before and after the surgical procedure improved from 1.2/6 to 6/6 in the first case, from light perception to 0.3/6 in the second case, from 0.6/6 to 4.8/6 in the third case. The vitreous was studied by different ultrastructural technics : transmission electron microscopy (T.E.M.) scanning electron microscopy (S.E.M.) and electron diffraction X ray analysis (E.D.A.X.). By S.E.M. the asteroïd bodies appeared as rounded structures with an irregular surface connected to each other by fibrous strands among sodium chloride crystals. No cellular remnants were observed. By T.E.M. the asteroïd bodies were composed of interwinned ribbons of multilaminar membranes with a periodicity (10 to 60 A) characteristic of complex lipids, especially phospholipids. At the edge of the ribbons there were dots and sometimes clumps of opaque material that tended to crack out of the specimen with the heat of the electron beam. T.E.M. study disclosed the irregular disposition of the calcific bodies. By E.D.A.X. the calcific composition of the rounded structures could be determined : calcium and phosphorus were the main elements detectable in asteroïd bodies of all sizes for all three patients. The average calcium counts for the three successive cases were : 18, 30, 43 and for phosphorus : 9, 14, 26. Potassium was found in the first case, and sulfur in the third case.(ABSTRACT TRUNCATED AT 250 WORDS)
The draft document is intended to be used as part of a process to identify what is known and, more importantly, what is not yet known that could be of value in assessing the broad implications of specific nanomaterials. Like previous case studies (see History/ Chronology below), this draft case study on multiwalled carbon nanotubes (MWCNTs) is based on the comprehensive environmental assessment (CEA) approach, which consists of both a framework and a process. Unlike previous case studies this case study incorporates information about a traditional (i.e., “non-nano-enabled”) product, against which the MWCNT flame-retardant coating applied to upholstery textiles (i.e., the “nano-enabled” product) can be compared. The comparative element serves dual-purposes: 1) to provide a more robust database that facilitates identification of data gaps related to the nano-enabled product and 2) to provide a context for identifying key factors and data gaps for future efforts to evaluate risk-related trade-offs between a nano-enabled and non-nano-enabled product. This draft case study does not represent a completed or even a preliminary assessment of MWCNTs; rather, it uses the CEA framework to structure information from available literature and other resources (e.g., government reports) on the product life cycle, fate and transport processes in various environmental media, exposure-dose characterization, and impacts in human, ecological, and environmental receptors.

As a continuation from summer 2012, the Shuttle Case Study Collection has been developed using lessons learned documented by NASA engineers, analysts, and contractors. Decades of information related to processing and launching the Space Shuttle is gathered into a single database to provide educators with an alternative means to teach real-world engineering processes. The goal is to provide additional engineering materials that enhance critical thinking, decision making, and problem solving skills. During this second phase of the project, the Shuttle Case Study Collection website was developed. Extensive HTML coding to link downloadable documents, videos, and images was required, as was training to learn NASA's Content Management System (CMS) for website design. As the final stage of the collection development, the website is designed to allow for distribution of information to the public as well as for case study report submissions from other educators online.

I teach an upper-level writing course, Genes, Race, Gender, and Society, designed for Life Science majors, in which I utilize a case study to expose students to ethical ways of thinking. Students first work through the topical case study and then are challenged to rethink their responses through the lenses of ethics, taking into account different ethical frameworks. Students then develop their own case study, integrating ethical components. I want to expose my students to this way of thinking because I see technology being driven by the Jurassic Park phenomenon, “Your scientists were so preoccupied with whether or not they could, they didn’t stop to think if they should,” and want future physicians grounded in a sense of how their actions relate to the greater good.

Palestinian refugees served by the United Nation Relief and Works Agency for Palestine Refugees in the Near East (UNRWA) are experiencing increasing rates of diagnosis of non-communicable diseases. In response, in 2011 UNRWA initiated an Agency-wide programme of primary healthcare reform, informed by the Chronic Care Model framework. Health services were reorganized following a family-centred approach, with delivery by multidisciplinary family health teams supported by updated technical advice. An inclusive clinical information system, termed e-Health, was implemented to collect a wide range of health information, with a focus on continuity of treatment. UNRWA was able to bring about these wide-ranging changes within its existing resources, reallocating finances, reforming its payment mechanisms, and modernizing its drug-procurement policies. While specific components of UNRWA's primary healthcare reform are showing promising results, additional efforts are needed to empower patients further and to strengthen involvement of the community.
Although the Jewish community of Palestine was an extremely family-oriented society and the institute of the family played a major role in the establishment of the new Zionist nationhood, the historiography has henceforth paid little attention to its role, images, and functions. This article will examine the diverse and often contradictory perceptions and influences that have shaped the Zionist period. Traditional Jewish perceptions intertwined with modern, bourgeois, and revolutionary notions of the family, whether national or socialist. These contradictory perceptions were manifested in the contested professional and public discourse regarding the many dysfunctional urban families in Tel Aviv, who were treated by welfare authorities and mental health specialists during the 1930s and 1940s.

Necrotizing fasciitis represents a group of highly lethal infections characterized by rapidly progressing inflammation and necrosis. The aim of the study was to analyze the clinical profile, microbial flora, and predisposing risk factors in patients with necrotizing fasciitis. Lastly, we aimed to formulate a protocol for management of necrotizing fasciitis. Forty-eight cases of necrotizing fasciitis patients who reported to our hospital between April 2007 and September 2009 were included in the study. The commonest predisposing factors were age greater than 50 years (58 % cases) and diabetes mellitus (52 % cases). The commonest site involved was extremity (70.8 %). Majority of infections were polymicrobial (87.5 %). Repeated aggressive debridement was the commonest surgical procedure performed. Early and aggressive surgical debridement, often in multiple sittings, supplemented by appropriate antibiotics and supportive therapy, forms the key to a successful outcome in necrotizing fasciitis.

Diagnosis of invasive pulmonary aspergillosis (IPA) is challenging. The objective of the study was to assess the value of microbiological tests to the diagnosis of IPA in the absence of non-specific radiological data. A retrospective study of 23 patients with suspicion of IPA and positivity of some microbiological diagnostic tests was performed. These tests included conventional microbiological culture, detection of Aspergillus galactomannan (GM) antigen and in some patients (1 → 3)-β-D-glucan (BDG) and Aspergillus fumigatus DNA using the LightCycler(®) SeptiFast test. In 10 patients with hematological malignancy, 6 cases were considered 'probable' and 4 'non-classifiable.' In 8 patients with chronic lung disease, 7 cases were classified as 'probable' and 1 as 'proven,' and in 5 patients with prolonged ICU stay (>7 days), there were 2 'proven' cases, 2 'non-classifiable' and 1 putative case. Microbiological culture was positive in 17 cases and 18 Aspergillus spp. were isolated (one mixed culture). A. fumigatus was the most frequent (44.4%) followed by A. tubingensis. The Aspergillus galactomannan (GM) antigen assay was positive in 21 cases (91.3%). The GM antigen and the (1 → 3)-β-D-glucan (BDG) assays were both performed in 12 cases (52.2%), being positive in 9. The SeptiFast test was performed in 7 patients, being positive in 4. In patients with non-classifiable pulmonary aspergillosis and one or more positive microbiological tests, radiological criteria may not be considered a limiting factor for the diagnosis of IPA.

Case studies of 3 green buildings with LEED certifications that required extensive acoustical retrofit work to become satisfactory work environments for their intended user groups will be used to define areas where green building design concepts and acoustical design concepts require reconciliation. Case study 1 is an office and conference center for a city environmental education agency. Large open spaces intended to collect daylight through clerestory windows provided large, reverberant volumes with few acoustic finishes that rendered them unsuitable as open office space and a conference room/auditorium. Case Study 2 describes one of the first gold LEED buildings in the southeast whose primary design concepts were so narrowly focused on thermal and lighting issues that they often worked directly against basic acoustical requirements resulting in sound levels of NC 50-55 in classrooms and faculty offices, crosstalk between classrooms and poor room acoustics. Case study 3 is an environmental education and conference center with open public areas, very high ceilings, and all reflective surfaces made from wood and other environmentally friendly materials that result in excessive loudness when the building is used by the numbers of people which it was intended to serve.

This draft document presents two case studies of nanoscale titanium dioxide (nano-TiO2) used (1) to remove arsenic from drinking water and (2) as an active ingredient in topical sunscreen. The draft case studies are organized around a comprehensive environmental assessment approach that combines a product life cycle framework with the risk assessment paradigm. The document does not draw conclusions about potential risks. Rather, the case studies are intended to help identify what needs to be known in order to conduct a comprehensive environmental assessment of the potential risks related to nano-TiO2. This draft document is part of a process that will inform the development of EPA’s research strategy to support nanomaterial risk assessments. The complex properties of various nanomaterials make evaluating them in the abstract or with generalizations difficult if not impossible. Thus, this document focuses on two specific uses of nano-TiO2, as a drinking water treatment and as topical sunscreen. These case studies do not represent completed or even preliminary assessments; rather, they present the structure for identifying and prioritizing research needed to support future assessments.

EPA announced the release of the final report, Nanomaterial Case Study: Nanoscale Silver in Disinfectant Spray. This report represents a case study of engineered nanoscale silver (nano-Ag), focusing on the specific example of nano-Ag as possibly used in disinfectant sprays. This case study is organized around the comprehensive environmental assessment (CEA) framework, which structures available information pertaining to the product life cycle, environmental transport and fate, exposure-dose in receptors (i.e., humans, ecological populations, and the environment), and potential impacts in these receptors. The document does not draw conclusions about potential risks. Instead, it is intended to be used as part of a process to identify what is known and unknown about nano-Ag in a selected application. In turn, the external review draft of the document provided a starting point to identify and prioritize possible research directions to support future assessments of nanomaterials. The information presented in the case study and the questions raised in this document are a foundation for a process to determine priorities among various research topics and directions. After that process has been completed, a final chapter will be added to this document to summarize highlights from preceding chapters and the major research issues that have emerged.

Fluid withdrawal, permafrost thaw, or large changes in pipe temperature can induce severe axial stresses on a well's casing, which often results in buckling. To minimize the cost of stabilizing the casing via cementing, engineers have developed new design criteria for preventing buckling; even for severe conditions, the resulting formulations cost less to use than those derived from previous criteria. Theoretical studies suggest that for a laterally supported pipe, the axial buckling force approaches a minimum asymptotic limit as the pipe length increases; thus the buckling equation for an infinitely long pipe can serve as a simple yet conservative design criterion for avoiding elastic axial buckling of any laterally supported casing. According to calculations, axial buckling can be prevented, even in a very long pipe, by surrounding the pipe with an elastic medium having a sufficiently high modulus.

The authors describe the founding of Hashomer Hatzair as a radical Zionist scouting movement in Eastern Europe between 1913 and 1919, a little known episode in the rich history of Freud's impact upon this century. As refugees in Vienna, the young adherents of the movement experienced enormous personal and collective turmoil. Desperate to construct new, viable identities, these intellectually vibrant young men and women were drawn to Freud as part of their project of self-creation. Beginning in the 1920s, as members of Hashomer Hatzair settled in agriculturally based collectives known as kibbutzim, the educational leadership of the movement argued that psychoanalytically informed education was the key to raising children free of bourgeois neuroses. They established strong ties with European analysts, translated and published psychoanalytic texts, insisted that educators be analysed or, at least, psychoanalytically informed, and built a complex educational system founded on their particular understanding of Freudian insights. For them, psychoanalysis was also seen as a general prophylactic guaranteeing the mental hygiene of the community as a whole. The authors examine the complex relationship between Hashomer Hatzair and psychoanalysis. In particular, they ask why these young adults were so drawn to Freud and what their particular reading of the psychoanalytic texts was, and demonstrate how these young pioneers created a 'usable Freud' as part of their project of designing and building a utopian society.

This study of cutaneous leishmaniasis in Jericho city and the adjacent Aqbat-Jaber refugee camp investigated the seroprevalance of Leishmania major and the risk factors associated with acquiring the disease. Clinical and parasitology identification of cases showed children and young men were more affected, with the head most affected in children. Enzyme-linked immunosorbent assay (ELISA) was used to test sera from 190 individuals. The overall seroprevalence of cutaneous leishmaniasis was 26.3%. A case-control study of 247 individual in 37 households showed that a higher level of education of the head of the household and having children sleep under bed nets were significantly related to a lower incidence of cutaneous leishmaniasis.

Background Publicly funded clinical trials require a substantial commitment of time and money. To ensure that sufficient numbers of patients are recruited it is essential that they address important questions in a rigorous manner and are managed well, adopting effective marketing strategies. Methods Using methods of analysis drawn from management studies, this paper presents a structured assessment framework or reference model, derived from a case analysis of the MRC's CRASH trial, of 12 factors that may affect the success of the marketing and sales activities associated with clinical trials. Results The case study demonstrates that trials need various categories of people to buy in – hence, to be successful, trialists must embrace marketing strategies to some extent. Conclusion The performance of future clinical trials could be enhanced if trialists routinely considered these factors. PMID:18028537

A case-study collection was developed for NASA's Space Shuttle Program. Using lessons learned and documented by NASA KSC engineers, analysts, and contractors, decades of information related to processing and launching the Space Shuttle was gathered into a single database. The goal was to provide educators with an alternative means to teach real-world engineering processes and to enhance critical thinking, decision making, and problem solving skills. Suggested formats were created to assist both external educators and internal NASA employees to develop and contribute their own case-study reports to share with other educators and students. Via group project, class discussion, or open-ended research format, students will be introduced to the unique decision making process related to Shuttle missions and development. Teaching notes, images, and related documents will be made accessible to the public for presentation of Space Shuttle reports. Lessons investigated included the engine cutoff (ECO) sensor anomaly which occurred during mission STS-114. Students will be presented with general mission infom1ation as well as an explanation of ECO sensors. The project will conclude with the design of a website that allows for distribution of information to the public as well as case-study report submissions from other educators online.

The Global Hydrology and Climate Center and NASA's Marshall Space Flight Center conducted a fact-finding case study for the Data Management Working Group (DMWG), now referred to as the Data and Information Working Group (DIWG), of the U.S. Global Change Research Program (USGCRP) to determine the feasibility of an interagency National Environmental Change Information System (NECIS). In order to better understand the data and information needs of policy and decision makers at the national, state, and local level, the DIWG asked the case study team to choose a regional water resources issue in the southeastern United States that had an impact on a diverse group of stakeholders. The southeastern United States was also of interest because the region experiences interannual climatic variations and impacts due to El Nino and La Nina. Jointly, with input from the DIWG, a focus on future water resources planning in the Apalachicola-Chattahoochee-Flint (ACF) River basins of Alabama, Georgia, and Florida was selected. A tristate compact and water allocation formula is currently being negotiated between the states and U.S. Army Corps of Engineers (COE) that will affect the availability of water among competing uses within the ACF River basin. All major reservoirs on the ACF are federally owned and operated by the U.S. Army COE. A similar two-state negotiation is ongoing that addresses the water allocations in the adjacent Alabama-Coosa-Tallapoosa (ACT) River basin, which extends from northwest Georgia to Mobile Bay. The ACF and ACT basins are the subject of a comprehensive river basin study involving many stakeholders. The key objectives of this case study were to identify specific data and information needs of key stakeholders in the ACF region, determine what capabilities are needed to provide the most practical response to these user requests, and to identify any limitations in the use of federal data and information. The NECIS case study followed the terms of reference

Isosurface extraction is an important and useful visualization method. Over the past ten years, the field has seen numerous isosurface techniques published leaving the user in a quandary about which one should be used. Some papers have published complexity analysis of the techniques yet empirical evidence comparing different methods is lacking. This case study presents a comparative study of several representative isosurface extraction algorithms. It reports and analyzes empirical measurements of execution times and memory behavior for each algorithm. The results show that asymptotically optimal techniques may not be the best choice when implemented on modern computer architectures.

EPA announced the availability of the final report, Nanomaterial Case Studies: Nanoscale Titanium Dioxide in Water Treatment and in Topical Sunscreen. This report is a starting point to determine what is known and what needs to be known about selected nanomaterials as part of a process to identify and prioritize research to inform future assessments of the potential ecological and health implications of these materials. Two specific applications of nanoscale titanium dioxide (nano-TiO2) are considered: (1) as an agent for removing arsenic from drinking water; and (2) as an active ingredient in topical sunscreen. These case studies are organized around a comprehensive environmental assessment (CEA) framework that combines a product life cycle perspective with the risk assessment paradigm. They are intended to help identify what may need to be known in order to conduct a comprehensive environmental assessment of the potential risks related to nano-TiO2. These “case studies” do not represent completed or even preliminary assessments, nor are they intended to serve as a basis for risk management decisions in the near term on these specific uses of nano TiO2. Rather, the intent is to use this document in developing the scientific and technical information needed for future assessment efforts.
This Independent Peer Review Draft document presents a case study of multiwalled carbon nanotubes (MWCNTs); it focuses on the specific example of MWCNTs as used in flame-retardant coatings applied to upholstery textiles. This case study is organized around the comprehensive environmental assessment (CEA) framework, which structures available information pertaining to the product life cycle, environmental transport and fate, exposure-dose in receptors (i.e., humans, ecological populations, and the environment), and potential impacts in these receptors. The document does not draw conclusions about potential risks, or present an exhaustive review of the literature. Rather, it was used in an independent peer review to provide feedback on revisions that EPA made to the external review draft of the document based on public comments and the CEA process to identify research gaps for MWCNTs. This document seeks to identify what is known and unknown related to assessing the health and environmental implications of a nanomaterial; in this case multiwalled carbon nanotubes (MWCNTs) used in flame-retardant coatings applied to textiles.

The teaching of biomaterials as case study by on-line platform , susceptible to develop both individually and in groups, got different objectives proposed by the European Higher Education System, among which include: participate actively in the teaching-learning process by students, interpreting situations, adapt processes and solutions. It also improves oral and written communication, analytical skills and synthesis and also the ability to think critically. Biomaterials have their origin in biominerals. These are solid inorganic compounds of defined structure, consisting of molecular control mechanisms that operate in biological systems. Its main functions are: structural support, a reservoir of essential elements, sensors, mechanical protection and storage of toxic elements. Following the demand of materials compatible with certain functional systems of our body, developed biomaterials. Always meet the condition of biocompatibility. Should be tolerated by the body and do not provoke rejection. This involves a comprehensive study of physiological conditions and the anatomy of the body where a biomaterial has to be implemented. The possibility of generating new materials from biominerals has a major impact in medicine and other fields could reach as geology, construction, crystallography, etc. While the study of these issues is in its infancy today, can be viewed as an impact on the art and future technology. Planning case study that students would prepare its report for discussion in subgroups. Occurs then the pooling of individual analysis, joint case discussion and adoption by the subgroup of a consensual solution to the problem. The teacher as facilitator and coordinator of the final case analysis, sharing leads to group-wide class and said the unanimous decision reached by the students and gives his opinion on the resolution of the case.

BACKGROUND: Lichen planus is considered to be the most common dermatological disease involving the oral mucosa. OBJECTIVE: To investigate the profile, clinical features, and the presence of dysplasia and candidiasis in patients with oral lichen planus. METHODS: A total of 21 patients were selected from 258 patients at risk for oral cancer development. RESULTS: Most of the patients were white (76,2%), female (66,6%), with mean age of 58.8 years. Eight were smokers and seven were alcohol consumers. The buccal mucosa was the most affected site, followed by the tongue and the gingiva. The reticular pattern was the most common appearance. Histopathology depicted dysplasia in nine cases and cytopathology was positive for Candida in eight cases in the first appointment. CONCLUSION: Our data are similar to the literature. Cytopathology was important for the diagnosis of candidiasis. Although the presence of dysplasia was verified, further studies are necessary to clarify the importance of this finding. PMID:26131860

Terahertz (THz) spectroscopy and imaging is a non-destructive, non-contact, non-invasive technology emerging as a tool for the analysis of cultural heritage. THz Time Domain Spectroscopy (TDS) techniques have the ability to retrieve information from different layers within a stratified sample, that enable the identification of hidden sub-layers in the case of paints and mural paintings. In this paper, we present the THz TDS2 system developed in the European Commission's 7th Framework Program project CHARISMA [grant agreement no. 228330]. Bespoke single processing algorithms; including a deconvolution algorithm can be deployed to increase the resolution and the global performance of the system. The potential and impact of this work is demonstrated through two case studies of mural paintings, where the capability to reveal the stratigraphy of the artworks is demonstrated.
The occurrence of a seasonal (summer) upwelling regime characterises the oceanography of the western Iberian margin. Surface manifestations of this process, in the form of cold filaments and eddies, are well documented in satelite imagery. In this contribution, observations and numerical modelling tools are combined to provide two contrasting views of the western Iberian upwelling. The first case study adresses the summer upwelling regime offshore the northern Portuguese coast. The study area is characterised by a rather regular coastline and shelf topography. Data from a program of observations conducted by Instituto Hidrografico, from May to October 1987, which included two hydrographic surveys and an array of three currentmeter moorings, is used to characterise the evolution of shelf and upper slope conditions along the complete upwelling season. The second case study will focus the developpment of an upwelling filament off Cape S. Vicent, in the southwestern tip of Portugal, during a period of sustained northerly winds in April 2001. The area is characterised by abrupt changes in coastline orientation and a complex topography (e.g Gorringe seamount). The dominant aspects of both the filament dynamics and shelf circulation are studied using a primitive equation model (Harvard Ocean Prediction System - HOPS) with assimilation of data collected during a hydrographic surveys conducted during April 2001.

Reinforcement Learning algorithms offer interesting features for the control of autonomous systems, such as the ability to learn from direct interaction with the environment, and the use of a simple reward signalas opposed to the input-outputs pairsused in classic supervised learning. The reward signal indicates the success of failure of the actions executed by the agent in the environment. In this work, are described RL algorithmsapplied to two case studies: the Crawler robot and the widely known inverted pendulum. We explore RL capabilities to autonomously learn a basic locomotion pattern in the Crawler, andapproach the balancing problem of biped locomotion using the inverted pendulum.
Irrigation water supply is furnished annually to about 71,500 acres of land in the Grand Valley of western Colorado. Return flows from that irrigation contribute about 780,000 tpy of salt to the Colorado River, causing an increase of 77 mg/l in the salinity concentration at Imperial Dam. A case study of water quality in this region is focused on: water quality data for irrigation and return flows/ identification of regulations that affect irrigation and return flows/ and a proposed program for controlling salinity levels.

The paths taken by each family in coming to terms with the dismal prognosis associated with brain stem glioma can be quite different. The case studies of 2 school-age girls diagnosed with a brain stem glioma within weeks of each other are presented. The multi-disciplinary team response to each family was individualized at each stage of diagnosis, treatment, and end-of-life care, as expected. The ultimate chronologic union of these 2 families as each child neared death was somewhat uncanny. The experience of each family, and their relationship with the team through this process, was an intense challenge and learning experience.

This analysis presents a case study in California for a large scale, standalone wind electrolysis site. This is a techno-economic analysis of the 40,000 kg/day renewable production of hydrogen and subsequent delivery by truck to a fueling station in the Los Angeles area. This quantity of hydrogen represents about 1% vehicle market penetration for a city such as Los Angeles (assuming 0.62 kg/day/vehicle and 0.69 vehicles/person) . A wind site near the Mojave Desert was selected for proximity to the LA area where hydrogen refueling stations are already built.

Patient: Male, 27 Final Diagnosis: Myonecrosis of sickle cell anaemia Symptoms: Pain • redness to feet • swelling foot Medication: — Clinical Procedure: MRI Specialty: Podiatry Objective: Rare disease Background: Myonecrosis is one of the more poorly studied, painful manifestations of sickle cell crisis. Medical literature is sparse detailing the manifestations and management of such symptoms. In myonecrosis, red cells containing sickle hemoglobin become rigid, resulting in reduced blood flow and myonecrosis. Case Report: We present a case study of a patient in sickle cell crisis with an episode of acute pain and swelling to the intrinsic muscles of the foot as a prominent feature of the crises. Although muscle biopsy is considered the gold standard for the diagnosis of myositis or myonecrosis, a low intensity signal on T1 and high intensity signal on T2 at the affected muscle belly can be as conclusive as imaging studies. In an actively sickling patient any invasive intervention should be avoided as it can result in ischemic necrosis of the tissues, due to interruption of capillary flow in end-arteries. Conclusions: Early recognition is critical in sickle cell disease management, allowing for prompt and aggressive fluid resuscitation which remains a cornerstone in the management of most sickle cell vaso-occlusive crises. In this instance, off loading the extremity and early fluid resuscitation resolved the pain and swelling and prevented myonecrosis. PMID:28133359

Pain is a widespread issue in the United States. Nine of 10 Americans regularly suffer from pain, and nearly every person will experience low back pain at one point in their lives. Undertreated or unrelieved pain costs more than $60 billion a year from decreased productivity, lost income, and medical expenses. The ability to diagnose and provide appropriate medical treatment is imperative. This case study examines a 23-year-old Active Duty woman who is preparing to be involuntarily released from military duty for an easily correctable medical condition. She has complained of chronic low back pain that radiates into her hip and down her leg since experiencing a work-related injury. She has been seen by numerous providers for the previous 11 months before being referred to the chronic pain clinic. Upon the first appointment to the chronic pain clinic, she has been diagnosed with sacroiliac joint dysfunction. This case study will demonstrate the importance of a quality lower back pain assessment.

California is the largest cement producing state in theU.S., accounting for between 10 percent and 15 percent of U.S. cementproduction and cement industry employment. The cement industry inCalifornia consists of 31 sites that consume large amounts of energy,annually: 1,600 GWh of electricity, 22 million therms of natural gas, 2.3million tons of coal, 0.25 tons of coke, and smaller amounts of wastematerials, including tires. The case study summarized in this paperfocused on providing background information, an assessment ofenergy-efficiency opportunities and barriers, and program recommendationsthat can be used by program planners to better target products to thecement industry. The primary approach to this case study involvedwalk-through surveys of customer facilities and in depth interviews withcustomer decision makers and subsequent analysis of collected data. Inaddition, a basic review of the cement production process was developed,and summary cement industry energy and economic data were collected, andanalyzed. The analysis of secondary data provides background informationon the cement industry and identification of potential energy-efficiencyopportunities. The interviews provide some understanding of the customerperspective about implementation of energy-efficiencyprojects.

RTCA DO-333, Formal Methods Supplement to DO-178C and DO-278A provides guidance for software developers wishing to use formal methods in the certification of airborne systems and air traffic management systems. The supplement identifies the modifications and additions to DO-178C and DO-278A objectives, activities, and software life cycle data that should be addressed when formal methods are used as part of the software development process. This report presents three case studies describing the use of different classes of formal methods to satisfy certification objectives for a common avionics example - a dual-channel Flight Guidance System. The three case studies illustrate the use of theorem proving, model checking, and abstract interpretation. The material presented is not intended to represent a complete certification effort. Rather, the purpose is to illustrate how formal methods can be used in a realistic avionics software development project, with a focus on the evidence produced that could be used to satisfy the verification objectives found in Section 6 of DO-178C.

The scheduling in job shop is important for efficient utilization of machines in the manufacturing industry. There are number of algorithms available for scheduling of jobs which depend on machines tools, indirect consumables and jobs which are to be processed. In this paper a case study is presented for scheduling of jobs when parts are treated on available machines. Through time and motion study setup time and operation time are measured as total processing time for variety of products having different manufacturing processes. Based on due dates different level of priority are assigned to the jobs and the jobs are scheduled on the basis of priority. In view of the measured processing time, the times for processing of some new jobs are estimated and for efficient utilization of the machines available an algorithm is proposed and validated.

Plant secondary metabolites (PSMs), such as alkaloids, are often found in many parts of a plant, including flowers, providing protection to the plant from various types of herbivores or microbes. PSMs are also present in the floral nectar of many species, but typically at lower concentrations than in other parts of the plant. Nectar robbers often damage floral tissue to access the nectar. By doing so, these nectar robbers may initiate an increase of PSMs in the floral nectar. It is often assumed that it takes at least a few hours before the plant demonstrates an increase in PSMs. Here, we addressed the question of whether PSMs in the floral tissue are immediately being released into the floral nectar following nectar robbing. To address this research question, we investigated whether there was an immediate effect of nectar robbing by the Palestine Sunbird (Nectarinia osea) on the concentration of nectar alkaloids, nicotine and anabasine, in Tree Tobacco (Nicotiana glauca). We found that the concentration of anabasine, but not nicotine, significantly increased in floral nectar immediately following simulated nectar robbing. These findings suggest that nectar robbers could be ingesting greater amounts of PSMs than they would if they visit flowers legitimately. As a consequence, increased consumption of neurotoxic nectar alkaloids or other PSMs could have negative effects on the nectar robber.

Many acceleration-sensitive, microgravity science experiments will require active vibration isolation from manned orbiters on which they will be mounted. The isolation problem, especially in the case of a tethered payload, is a complex three-dimensional one that is best suited to modern-control design methods. In this paper, extended H(sub 2) synthesis is used to design an active isolator (i.e., controller) for a realistic single-input-multiple-output (SIMO) microgravity vibration isolation problem. Complex mu-analysis methods are used to analyze the isolation system with respect to sensor, actuator, and umbilical uncertainties. The paper fully discusses the design process employed and the insights gained. This design case study provides a practical approach for isolation problems of greater complexity. Issues addressed include a physically intuitive state-space description of the system, disturbance and noise filters, filters for frequency weighting, and uncertainty models. The controlled system satisfies all the performance specifications and is robust with respect to model uncertainties.

Measured energy performance data are essential to national efforts to improve building efficiency, as evidenced in recent benchmarking mandates, and in a growing body of work that indicates the value of permanent monitoring and energy information feedback. This paper presents case studies of energy information systems (EIS) at four enterprises and university campuses, focusing on the attained energy savings, and successes and challenges in technology use and integration. EIS are broadly defined as performance monitoring software, data acquisition hardware, and communication systems to store, analyze and display building energy information. Case investigations showed that the most common energy savings and instances of waste concerned scheduling errors, measurement and verification, and inefficient operations. Data quality is critical to effective EIS use, and is most challenging at the subsystem or component level, and with non-electric energy sources. Sophisticated prediction algorithms may not be well understood but can be applied quite effectively, and sites with custom benchmark models or metrics are more likely to perform analyses external to the EIS. Finally, resources and staffing were identified as a universal challenge, indicating a need to identify additional models of EIS use that extend beyond exclusive in-house use, to analysis services.

This paper presents an application of the Urban and Lambert "upgraded-AJL Decomposition" approach that was designed to deal with the problem of close-income equals in equity analysis, and as applied to the area of health care finance. Contrary to most previous studies, vertical and horizontal inequities and the triple effects of inter-groups, intra-group and entire-group reranking of various financing schemes are estimated, with statistical significance calculated using the bootstrap method. Application is made on the three financing schemes present in the case of the Occupied Palestinian Territory. Results demonstrate the relative importance of the three forms of reranking in determining overall inequality. The paper offers policy recommendations to limit the existing inequalities in the system and to enhance the capacity of the governmental insurance scheme.

This article describes a case study of a hypnotherapeutic treatment of nocturnal bruxism. The author saw the client for a total of 7 sessions. Hypnotherapy was interspersed with an exploration of tacit and initially denied hostility in the client's life as well as aspects of a somewhat difficult childhood. At the end, the bruxism had disappeared. Follow-up 1 year later indicated that the bruxism had not returned, and the client had become more assertive in her relations with others and had more exploratory activities in her life directions. The latter had not been dealt with in therapy. Thus, there appeared to be a "ripple effect" of successful therapy from one part of her life into its other aspects.

Seventeen cases of late ulnar paralysis treated by neurolysis-transposition are reported. The clinical characteristics of these paralysis are emphasized. A very prolonged symptom free interval, a rapid onset and a severe involvement. The ulnar transposition was most often done subcutaneously. Cubitus valgus and definite nerve compression proximal to the arcade of the flexor carpi ulnaris muscle are almost always present. The results as regards the neuropathy are notable: no patient is completely cured and only half are improved. An anatomical study of the nerve path shows the essential role, in the compression of the nerve, of the muscular arcade of the flexor carpi ulnaris muscle which acts in a way similar to the bridge of a violin. Hence, opening it longitudinally is the principal procedure of the neurolysis. This should be routine before the first signs of neuropathy occur in an elbow whose axis is out of alignment as a sequela of a childhood injury.

This paper focuses on three seemingly unrelated error patterns in the sound system of a child with a phonological delay, Child 218 (male, age 4 years 6 months) and ascribes those error patterns to a larger conspiracy to eliminate fricatives from the phonetic inventory. Employing Optimality Theory for its advantages in characterizing conspiracies, our analysis offers a unified account of the observed repairs. The contextual restrictions on those repairs are, moreover, attributed to early developmental prominence effects, which are independently manifested in another error pattern involving rhotic consonants. Comparisons are made with a published case study involving a different implementation of the same conspiracy, the intent being to disambiguate the force behind certain error patterns. The clinical implications of the account are also considered.

This article explores the importance of quality practices in underpinning the person-centred approach at a Community Options Program (COP) case management service in northern NSW. The NSW community care sector does not have a statutory excellence body to identify, promote and support improved practices and quality and safety across community services, and therefore the COP provider decided to establish a dedicated role to focus on the quality improvement of its service. The subsequent quality improvement initiatives have included mapping the clients' journey through the service, identifying areas to standardise practice, and creating service pathways. The clients' journey was used as the framework to identify where standardised practice was required, and a robust process was implemented to develop over 25 good practice guidelines and tools that addressed the variations in practice and enabled the service pathways to be developed. Prior to trialling the guidelines and tools, staff received education sessions on the anticipated changes to practice, and the practicality and applicability of the guidelines were evaluated at the end of the trials. This information was reviewed and the guidelines were amended accordingly before being rolled out. The guidelines have been in use for over 12 months and have provided the benchmark against which to audit practice, and have resulted in key performance improvements such as an increase in client review rates and a rise in the feedback response rate from clients, with a noticeable shift in the comments about the brokered support worker to acknowledging the role of their case manager. Formalising informal supports for those clients that lived alone also increased, which means these people are less reliant on services and there is a reduced risk of social isolation.

The study of planets around other stars has entered a science-rich era of characterization, in which detailed information about individual planets can be inferred from observations beyond mere detection, which only yields bulk properties like mass or radius. Characterization probes more revealing quantities such as chemical abundances, albedo, and temperature/pressure profiles, which allow us to address larger questions of planet formation mechanisms, planetary evolution, and, eventually, habitability and presence of biosignature gases. The primary method for characterization of close-in planets is transit spectroscopy. This dissertation talk will focus on transiting exoplanet case studies with the Hubble Space Telescope’ Wide-Field Camera-3 (WFC-3) as a tool of exoplanet characterization in a near-infrared band dominated by strong water features. I will first present a characterization the WFC-3 systematic effects that must be mitigated to extract the incredibly small (tens to 200 parts per million) signals, and then a study of four transiting giant planets (HATS-7b, HAT-p-3b, HD 149026b, and WASP-18b) in transmission, and two (WASP-18b and CoRoT-2b) in eclipse. Finally, I will discuss the role of transit timing monitoring of WASP-18b with HST and other observatories as another clue to its evolution as a close-in, massive planet. The five planets range from Neptune-class to Super-Jupiter-class in size/mass. Though these planets may be relatively rare, their observability represents a unique opportunity to probe planet formation and evolution, as well as atmospheric structures in a high-irradiation environment. These observations also yield insights into aerosols (i.e. clouds/hazes) in the atmosphere; clouds and/or hazes should significantly impact atmospheric chemistry and observational signatures, and we as a community must get a better handle on the phenomenon of aerosols in advance of the next generation of space observatories, including JWST and WFIRST

Landslide economics is vital for fundamental understanding of landslide risk as dealing with two important topics: (i) impact assessment, either as damage statistics or cost modeling, and (ii) vulnerability assessment, i.e., the study of exposure, sensitivity, and resilience to landslide damage, ideally from both sociotechnical and financial perspective (e.g., Crovelli and Coe, 2009; Wills et al., 2014). Many aspects addressed in landslide economics have direct influence on landslide risk, including: (i) human activity is often a major causative factor of landslides, not only by predisposing or triggering them, but also as a result of inadequate (low-cost) landslide mitigation; (ii) the level of tolerable or acceptable risk, a measure driving a large part of landslide costs in industrialized countries, is highly variable, differing between individuals, public or private organizations, and societies, with its nature being to change over time; and (iii) decision makers are faced with finding the right balance in landslide mitigation, thus need to weight diverse geological and socioeconomic factors that control its effectiveness in both technical and financial terms (e.g., Klose et al., 2014a). A large part of the complexity in assessing landslide risk as measured by economic costs is due to unique problems in understanding of (i) what types of landslide damage affect human activity and infrastructure in which way, (ii) how society contributes and responds to various kinds of damage, and (iii) how landslide damage is valued in monetary terms. Landslide economics shows the potential to take account of these sociocultural factors to the benefit of risk analysis (e.g., Klose et al., 2014b). The present contribution introduces local and regional case studies in which different economic issues of landslide risk are highlighted using the example of public infrastructures in NW Germany. A special focus is on the following topics: (i) risk culture and created risk, (ii

A 4-year case study was made of a 42-year-old white woman as seen through the psychophysiological diary. There was an awakening diary and a bedtime diary composed of 125 variables. The data are divided into two series: series I containing a manic episode, and series II as a control. Spectral analysis shows infradian rhythms in hypoglycemia and fear (11 days) and time to fall asleep (5 days). Depressed feelings showed a circatrigintan (28-day) rhythm, which was not correlated with menses. Mania had an annual rhythm (spring) but no circatrigintan or less rhythm. The following correlations have a P value less than or equal to 0.01: mania was directly correlated with number of sleeping pills, time to really wake up, need for rest, moodiness, and helplessness, and indirectly with expectations, pressure at work, sense of time, and emotional state. Interestingly, awakening pulse is directly correlated with awakening temperature, number of sleeping pills, bedtime pulse, tiredness at bedtime, hypoglycemia, and fear. Bedtime pulse is directly correlated with awakening pulse and awakening temperature. Both pulse and temperature at bedtime are directly correlated with negative variables such as tiredness, moodiness, helplessness, and depression, and inversely correlated with positive variables such as happiness, loving, performance at work, and thinking efficiency. This study demonstrates a significant correlation between physiological variables.

We present a prospective study of 88 patients with thyroid nodules seen in our institution in 1985-86 and the results of a 5 year follow up. The algorithm for resolution among different therapeutic options was established in regard to the clinical characteristics, imaging and particularly the histopathologic studies. Their age ranged from 18 to 79 years; 94% of the patients were females. Most of the nodules were solid (69%) and measured 1-4 cm in diameter. The image of 62% of the thyroid scans was of a non-functioning nodule and 13% were hyperfunctioning. In 80% the ultrasonographic pattern was solid or mixed. Surgery was undertaken in 19 patients (21%). In 58%, a diagnosis of malignancy was established. The biopsy (aspiration and tru-cut) suggested the presence of the malignant tumors when taken together in 90% of the cases. Hormonal treatment was given to 62 patients; in 40-45% of them there was a significant reduction in the size of the nodule. Aspiration and sclerosis of cystic nodules were performed in 19 patients with significant shrinkage in 82%. Radioactive iodine was used in 11 patients. Our algorithm reduces costs and precludes unnecessary morbidity in patients with thyroid nodules.

The authors studied eight sets of healthy twins, ranging in physical maturity from prepubertal to late pubertal, and their parents, to assess psychological changes in early adolescence. A phase-specific psychosocial regression correlates with the biological onset of puberty. We present preliminary findings related to twinship, parental reactions, and longitudinal development, based on detailed case studies. Parents experienced increased conflict, detachment, and pride in response to their twins' psychosocial development at puberty. The more advanced child in a pair tended to lead in all spheres of adjustment-school success, heterosexual interest, peer friendships, and independent behavior. Although the more advanced child began to break away from his twin, in general the twin relationships remained close. Differences in personality traits and rate of psychosocial development within a twinship tended to remain consistent or to become accentuated. They were occasionally narrowed but rarely reversed from early childhood through early adolescence. Some of the differences were fostered by dissimilar patterns of identifying with the parents.

This research documents and demonstrates viable approaches using existing materials, tools and technologies in owner-conducted deep energy retrofits (DERs). These retrofits are meant to reduce energy use by 70% or more, and include extensive upgrades to the building enclosure, heating, cooling and hot water equipment, and often incorporate appliance and lighting upgrades as well as the addition of renewable energy. In this report, 11 Northern California (IECC climate zone 3) DER case studies are described and analyzed in detail, including building diagnostic tests and end-use energy monitoring results. All projects recognized the need to improve the home and its systems approximately to current building code-levels, and then pursued deeper energy reductions through either enhanced technology/ building enclosure measures, or through occupant conservation efforts, both of which achieved impressive energy performance and reductions. The beyond-code incremental DER costs averaged $25,910 for the six homes where cost data were available. DERs were affordable when these incremental costs were financed as part of a remodel, averaging a $30 per month increase in the net-cost of home ownership.

To what extent and in what arenas do collaborating musicians need to understand what they are doing in the same way? Two experienced jazz musicians who had never previously played together played three improvisations on a jazz standard ("It Could Happen to You") on either side of a visual barrier. They were then immediately interviewed separately about the performances, their musical intentions, and their judgments of their partner's musical intentions, both from memory and prompted with the audiorecordings of the performances. Statements from both (audiorecorded) interviews as well as statements from an expert listener were extracted and anonymized. Two months later, the performers listened to the recordings and rated the extent to which they endorsed each statement. Performers endorsed statements they themselves had generated more often than statements by their performing partner and the expert listener; their overall level of agreement with each other was greater than chance but moderate to low, with disagreements about the quality of one of the performances and about who was responsible for it. The quality of the performances combined with the disparities in agreement suggest that, at least in this case study, fully shared understanding of what happened is not essential for successful improvisation. The fact that the performers endorsed an expert listener's statements more than their partner's argues against a simple notion that performers' interpretations are always privileged relative to an outsider's.

Technical concerns with integrating higher penetrations of photovoltaic (PV) systems include grid stability, voltage regulation, power quality (voltage rise, sags, flicker, and frequency fluctuations), and protection and coordination. The current utility grid was designed to accommodate power flows from the central generation source to the transmission system and eventually to the distribution feeders. At the distribution level, the system was designed to carry power from the substation toward the load. Renewable distributed generation, particularly solar PV, provides power at the distribution level challenging this classical paradigm. As these resources become more commonplace the nature of the distribution network and its operation is changing to handle power flow in both directions. This report is focused on large PV installations in which penetration is significantly greater than 15% of maximum daytime feeder load. These case studies are intended to demonstrate success stories with integration of large PV plants at the distribution level as well as some of the solutions used by the utility to ensure safe, reliable operation of both the PV system and the distribution network.

Floods are among the most frequent and costly natural disasters in terms of human hardship and economic loss. Depending on topography, soil condition, ground cover, human settlements and other factors, flood can produce catastrophic impacts both in terms of damages and modification of the landscape. The Salerno province experienced numerous flooding events after heavy thunderstorm, that triggered intense landslides (debris-mudflow), inundations, denudation, shore line progradation, etc. Recent study (Porfido et al. 2009) show that in this area more than 100 flooding events occurred since 1500. Among these four events have been estimate in the maximum severity class. Research into the historical flooding highlights the case of the event of 11 November 1773 as one of the major flooding occurred in Cava de' Tirreni, Campanian region, Southern Italy. About 400 - 450 people died; severe damage to the buildings were registered in a wide area of the Salerno province; several mud flows invested large areas of coastal territory which caused progradation phenomena of the shoreline of several hundreds of meters. The main objectives of this paper are: the historical reconstruction of the event considering contemporary documents found at Archives and National Libreries; characterization of the rainfall timing using historical descriptions; delimitation of inundated area; distribution of damage levels and identification and classification of flood-induced geological phenomena.

Leishmaniasis in many ways offers a unique vaccine case study. Two reasons for this are that leishmaniasis is a disease complex caused by several different species of parasite that are highly related, thus raising the possibility of developing a single vaccine to protect against multiple diseases. Another reason is the demonstration that a leishmaniasis vaccine may be used therapeutically as well as prophylactically. Although there is no registered human leishmaniasis vaccine today, immunization approaches using live or killed organisms, as well as defined vaccine candidates, have demonstrated at least some degree of efficacy in humans to prevent and to treat some forms of leishmaniasis, and there is a vigorous pipeline of candidates in development. Current approaches include using individual or combined antigens of the parasite or of salivary gland extract of the parasites' insect vector, administered with or without formulation in adjuvant. Animal data obtained with several vaccine candidates are promising and some have been or will be entered into clinical testing in the near future. There is sufficient scientific and epidemiological justification to continue to invest in the development of vaccines against leishmaniasis.

Mapping a set of categorical values to different colors is an elementary technique in data visualization. Users of visualization software routinely rely on the default colormaps provided by a system, or colormaps suggested by software such as ColorBrewer. In practice, users often have to select a set of colors in a semantically meaningful way (e.g., based on conventions, color metaphors, and logological associations), and consequently would like to ensure their perceptual differentiation is optimized. In this paper, we present an algorithmic approach for maximizing the perceptual distances among a set of given colors. We address two technical problems in optimization, i.e., (i) the phenomena of local maxima that halt the optimization too soon, and (ii) the arbitrary reassignment of colors that leads to the loss of the original semantic association. We paid particular attention to different types of constraints that users may wish to impose during the optimization process. To demonstrate the effectiveness of this work, we tested this technique in two case studies. To reach out to a wider range of users, we also developed a web application called Colourmap Hospital.

Recent work on solar wind plasma correlations using data from several widely-separated spacecraft (IMP 8, INTERBALL-1, WIND, and ISEE-3) has shown that, for 6-hour periods, the average plasma correlation is ~0.7. The focus of these studies has been directed toward a statistical understanding of gross solar wind correlation behavior. In all correlations examined, lower average correlations are caused by the presence of many points from the low correlation subpopulation; nevertheless, data points from the high correlation population are still present. No single organizational factor has yet been found which adequately separates low-correlation periods from high-correlation periods. Some of the spread in correlations is due to the spatial orientations and dimensions of solar wind structures, and thus to the locational alignments of the spacecraft being correlated, but this does not adequately explain all the good or poor correlations since sometimes three nearby spacecraft show poor correlations, while sometimes three widely-separated space-craft show good correlations. Thus, in order to understand the underlying physics, detailed investigation of individual cases has been undertaken. These results will be important in assigning quality measures to space weather predictions using satellite measurements taken at L1, for example.
This report describes the Bayesian approach to probability theory with emphasis on the application to the evaluation of experimental data. A brief summary of Bayesian principles is given, with a discussion of concepts, terminology and pitfalls. The step from Bayesian principles to data processing involves major numerical efforts. We address the presently employed procedures of numerical integration, which are mainly based on the Monte Carlo method. The case studies include examples from electron spectroscopies, plasma physics, ion beam analysis and mass spectrometry. Bayesian solutions to the ubiquitous problem of spectrum restoration are presented and advantages and limitations are discussed. Parameter estimation within the Bayesian framework is shown to allow for the incorporation of expert knowledge which in turn allows the treatment of under-determined problems which are inaccessible by the traditional maximum likelihood method. A unique and extremely valuable feature of Bayesian theory is the model comparison option. Bayesian model comparison rests on Ockham's razor which limits the complexity of a model to the amount necessary to explain the data without fitting noise. Finally we deal with the treatment of inconsistent data. They arise frequently in experimental work either from incorrect estimation of the errors associated with a measurement or alternatively from distortions of the measurement signal by some unrecognized spurious source. Bayesian data analysis sometimes meets with spectacular success. However, the approach cannot do wonders, but it does result in optimal robust inferences on the basis of all available and explicitly declared information.

To what extent and in what arenas do collaborating musicians need to understand what they are doing in the same way? Two experienced jazz musicians who had never previously played together played three improvisations on a jazz standard (“It Could Happen to You”) on either side of a visual barrier. They were then immediately interviewed separately about the performances, their musical intentions, and their judgments of their partner's musical intentions, both from memory and prompted with the audiorecordings of the performances. Statements from both (audiorecorded) interviews as well as statements from an expert listener were extracted and anonymized. Two months later, the performers listened to the recordings and rated the extent to which they endorsed each statement. Performers endorsed statements they themselves had generated more often than statements by their performing partner and the expert listener; their overall level of agreement with each other was greater than chance but moderate to low, with disagreements about the quality of one of the performances and about who was responsible for it. The quality of the performances combined with the disparities in agreement suggest that, at least in this case study, fully shared understanding of what happened is not essential for successful improvisation. The fact that the performers endorsed an expert listener's statements more than their partner's argues against a simple notion that performers' interpretations are always privileged relative to an outsider's.

Software reuse has several obvious advantages. By taking advantage of the experience and skill of colleagues one not only saves time, money and resources, but can also jump start a project that might otherwise have floundered from the start, or not even have been possible. One of the least talked about advantages of software reuse is it helps keep the work interesting for the developers. Reuse prevents developers from spending time and energy writing software solutions to problems that have already been solved, and frees them to concentrate on solving new problems, developing new components, and doing things that have never been done before. At the National Snow and Ice Data Center we are fortunate our user community has some unique needs that aren't met by mainstream solutions. Consequently we look for reuse opportunities wherever possible so we can focus on the tasks that add value for our user community. This poster offers a case study of one thread through a decade of reuse at NSIDC that has involved eight different development efforts to date.

We selected three case studies to illustrate environmental injustice issues in the South. These examples relate to migrant agricultural workers, the maquiladora industry and artisanal mining, while reviewing some of the major mechanisms involved, e.g. multinational corporations, the development of free trade zones, multilateral free trade agreements and the export of hazards. A series of strategies are discussed in order to address environmental injustice and health disparities that exist on a global scale. Some of the recommendations involve policy initiatives; others, such as research and mentorship, fall within the traditional domain of public health practice. In this paper, special attention is given to concerned environmental and occupational health professionals using evidence-based data for advocacy. For lasting changes to be made, however, stronger institutions and legislation are required. Those who have the 'right to know' about environmental injustice issues include communities of concern, workers' representatives and lawyers. Government officials and company officials may eventually work on the basis of conflict resolution, compensation and remediation, to quote some examples. Systematic approaches to protect both the environment and public health must be updated.
Migraine headaches are common and among the most disabling nonfatal conditions of humankind. They are frequently misdiagnosed, which may lead to undertreatment. Patients often self-diagnose and self-medicate, resulting in inadequate treatment. Consequently, patients may take additional doses, trying to gain relief with inappropriate medications. Rebound can ensue. With adequate treatment, a patient's condition and quality of life may improve considerably. Patient education is extremely important to help patients identify appropriate self-care measures, such as identification of triggering events and coping with the chronic nature of their condition. This case study presents a patient who began experiencing migraines following a neck injury. His headaches became more frequent, and ergotamine and caffeine (Cafergot) suppositories were prescribed. When he presented, he was experiencing daily headaches and using daily ergotamine and caffeine suppositories. He was using the emergency department (ED) frequently because of severe headaches. Cervical spasm was recognized as his trigger, and the ergotamine and caffeine suppositories were discontinued. After 3 days of severe headaches, his rebound ceased. He reverted back to episodic migraines, which he treated with zolmitriptan (Zomig) nasal spray, which was effective. His cervical spasm was treated with botulinum toxin type A (Botox), with excellent results. He has maintained reasonable headache control for 2 years.

Dynamic programming is typically applied to optimization problems. As the analytical solutions are generally very difficult, chosen software tools are used widely. These software packages are often third-party products bound for standard simulation software tools on the market. As typical examples of such tools, TOMLAB and DYNOPT could be effectively applied for solution of problems of dynamic programming. DYNOPT will be presented in this paper due to its licensing policy (free product under GPL) and simplicity of use. DYNOPT is a set of MATLAB functions for determination of optimal control trajectory by given description of the process, the cost to be minimized, subject to equality and inequality constraints, using orthogonal collocation on finite elements method. The actual optimal control problem is solved by complete parameterization both the control and the state profile vector. It is assumed, that the optimized dynamic model may be described by a set of ordinary differential equations (ODEs) or differential-algebraic equations (DAEs). This collection of functions extends the capability of the MATLAB Optimization Tool-box. The paper will introduce use of DYNOPT in the field of dynamic optimization problems by means of case studies regarding chosen laboratory physical educational models.

A case study of the impact of Ada on a Command and Control project completed at the Jet Propulsion Laboratory (JPL) is given. The data for this study was collected as part of a general survey of software costs and productivity at JPL and other NASA sites. The task analyzed is a successful example of the use of rapid prototyping as applied to command and control for the U.S. Air Force and provides the U.S. Air Force Military Airlift Command with the ability to track aircraft, air crews and payloads worldwide. The task consists of a replicated database at several globally distributed sites. The local databases at each site can be updated within seconds after changes are entered at any one site. The system must be able to handle up to 400,000 activities per day. There are currently seven sites, each with a local area network of computers and a variety of user displays; the local area networks are tied together into a single wide area network. Using data obtained for eight modules, totaling approximately 500,000 source lines of code, researchers analyze the differences in productivities between subtasks. Factors considered are percentage of Ada used in coding, years of programmer experience, and the use of Ada tools and modern programming practices. The principle findings are the following. Productivity is very sensitive to programmer experience. The use of Ada software tools and the use of modern programming practices are important; without such use Ada is just a large complex language which can cause productivity to decrease. The impact of Ada on development effort phases is consistent with earlier reports at the project level but not at the module level.

This article describes a case of Shared Psychotic Disorder in a married couple. Because only one of the partners of the pair (the inducer) was alive, at the time of the research, the other partner (the recipient) is presented by using a "psychological autopsy" based both on 19 tape recordings containing her delusional recollections and on a history provided by the husband. The content of their delusion, shaped by a fantasy theme of contemporary Western culture, is unique among cases of Shared Psychotic Disorder published in the last 30 years. The discussion following the case presentation draws attention to the potential risk of this type of case leading to a homicide-suicide pact. Additionally, comments are made about both the pathogenesis, with emphasis on psychodynamic hypothesis, and a consideration of the prognosis, which seems modulated by cultural factors.

This paper attempts a partial, critical look at the construction and use of case studies in ethics education. It argues that the authors and users of case studies are often insufficiently aware of the literary nature of these artefacts: this may lead to some confusion between fiction and reality. Issues of the nature of the genre, the fictional, story-constructing aspect of case studies, the nature of authorship, and the purposes and uses of case studies as "texts" are outlined and discussed. The paper concludes with some critical questions that can be applied to the construction and use of case studies in the light of the foregoing analysis.

Genome-wide association studies (GWAS) explore the relationship between genome variability and disease susceptibility with either population- or family-based data. Here, we have evaluated the utility of combining population- and family-based statistical association tests and have proposed a method for reducing the burden of multiple testing. Unrelated singleton and parent-offspring trio cases and controls from the Genetics of Kidneys in Diabetes (GoKinD) study were analyzed for genetic association with diabetic nephropathy (DN) in type 1 diabetics (T1D). The Cochran-Armitage test for trend and the family-based association test were employed using either unrelated cases and controls or trios, respectively. In addition to combining single nucleotide polymorphism (SNP) p-values across these tests via Fisher's method, we employed a novel screening approach to rank SNPs based on conditional power for more efficient testing. Using either the population-based or family-based subset alone predictably limited resolution to detect DN SNPs. For 384,197 SNPs passing quality control (QC), none achieved strict genome-wide significance (1.4 × 10−7) using 1171 singletons (577/594 cases/controls) or 1738 pooled singletons and offspring probands (841/897). Similarly, none of the 352,004 SNPs passing QC in 567 family trios (264/303 case/control proband trios) reached genome-wide significance. Testing the top 10 SNPs ranked using aggregated conditional power resulted in two SNPs reaching genome-wide significance, rs11645147 on chromosome 16 (p = 1.74 × 10−4 < 0.05/10 = 0.005) and rs7866522 on chromosome 9 (p = 0.0033). Efficient usage of mixed designs incorporating both unrelated and family-based data may help to uncover associations otherwise difficult to detect in the presence of massive multiple testing corrections. Capitalizing on the strengths of both types while using screening approaches may be useful especially in light of large-scale, next-generation sequencing and rare

Biostratigraphic case studies of six major extinctions show all are gradual save one, which is a catastrophic extinction of terrestrial origin. These extinctions show a continuum of environmental insults from major to minor. The major causes of these extinctions are positive and negative eustatic sea level changes, temperature, or ecological competition. Extraterrestrial causes should not be posited without positive association with a stratigraphically sharp extinction. The Cretaceous-Tertiary terrestrial extinction is considerably smaller in percentage of extinction than the marine extinction and is spread over 10 my of the Cretaceous and 1 my of the Tertiary. Sixty percent of the 30 dinosaurs in the northern Great Plains of the U.S. and Canada had become extinct in the 9 my before the late Maastrichtian sea level drop. The best data on the Permo-Triassic terrestrial extinction are from the Karoo basin of South Africa. This is a series of 6 extinctions in some 8 my, recorded in some 2800 meters of sediment. Precision of dating is enhanced by the high rate of accumulation of these sediments. Few data are readily available on the timing of the marine Permo-Triassic extinction, due to the very restricted number of sequences of Tatarian marine rocks. The terminal Ordovician extinction at 438 my is relatively rapid, taking place over about 0.5 my. The most significant aspect of this extinction is a eustatic sea level lowering associated with a major episode of glaciation. New data on this extinction is the reduction from 61 genera of trilobites in North America to 14, for a 77 percent extinction. Another Ordovician extinction present over 10 percent of the North American craton occurs at 454 my in the form of a catastrophic extinction due to a volcanic eruption which blanketed the U.S. east of the Transcontinental Arch. This is the only other sizeable extinction in the Ordovician.

This case study compares two different clinical outcomes for a patient with a long-standing psychotic disorder prescribed clozapine on two occasions. During the first trial, clozapine was used at a higher dose for this patient (350-450mg/day) and included clinically significant sialorrhea, pneumonia, and pneumonia-like illnesses requiring immediate medical intervention including hospitalization. There were also patient complaints of fatigue, cough, choking, and constipation leading to poor adherence. Clozapine was discontinued when the patient withdrew his consent due to side effects, despite his awareness of its benefits, including reduction of command hallucinations and irritability. The second clozapine trial was associated with lower daily doses and therapeutic serum blood levels. The patient was actively participating in and adhering to the medication plan. A very narrow window of clozapine dose was exceeded for two days and the patient complained of hypersalivation, cough, and lethargy. He was subsequently hospitalized for a two week period to treat aspiration pneumonia. This hospitalization helped establish the ideal daily dose of clozapine for this patient and also brought the relationship between aspiration pneumonia and clozapine to the attention of the psychiatrist and medical specialist. Once the appropriate dosage for this patient was established, his psychotic and affective symptoms were controlled, he was not hampered by adverse side effects, and he started to actively participate in social and recreational activities and plans that culminated in discharge from a state psychiatric facility to a supportive community residence. It is our hope that the lessons we have learned from our shared experience with this patient will be of benefit to other clinicians and patients.

Background Erythroderma is a rare skin disorder that may be caused by a variety of underlying dermatoses, infections, systemic diseases and drugs. Methods We reviewed the clinical, laboratory and biopsy material of 97 patients diagnosed with erythroderma who were treated in our department over a 6-year period (1996 through 2002). Results The male-female ratio was 1.85:1. The mean age at diagnosis was 46.2 years. The most common causative factors were dermatoses (59.7%), followed by drug reactions (21.6%), malignancies (11.3%) and idiopathic causes (7.2%). Carbamazepine was the most common drug (57.1%). The best clinicopathologic correlation was found in cutaneous T-cell lymphoma and pityriasis rubra pilaris related erythroderma. Apart from scaling and erythema that were present in all patients, pruritus was the most common finding (97.5%), followed by fever (33.6%), lymphadenopathy (21.3%), edema (14.4%) and hyperkeratosis (7.2%). Conclusion This study outlines that underlying etiologic factors of erythroderma may show geographic variations. Our series had a high percentage of erythroderma secondary to preexisting dermatoses and a low percentage of idiopathic cases. There was no HIV-infected patient among our series based on multiple serum antibody tests. The clinical features of erythroderma were identical, irrespective of the etiology. The onset of the disease was usually insidious except in drug-induced erythroderma, where it was acute. The group associated with the best prognosis was that related to drugs. PMID:15882451

Introduction: Mutiple mieloma (MM) cells are rarely found in extramedullary sites. The sites of extramedullary dissemination reported in the literature are spleen, liver, lymph nodes, kidneys, thyroid gland, adrenal gland, ovary, tests, lung, pleura, pericardium, intestinal tract and skin. We report a case in which the myeloma was diagnosed after we discovered the presence of monoclonal plasma cells in the bronchoalveolar lavage fluid (BAL). Matherial and method: a case in which diagnosis was established from bronchoalveolar lavage (BAL) fluid demonstrating the presence of monoclonal plasma cells in Craiova Pneumology Departament. Results: Analysis of BAL fluid for the presence of plasma cells and for cytoplasmic immunoglobulin DNA provides a noninvasive means of establishing the diagnosis. Conclusions: Pulmonary parenchyma is an uncommon site of extramedullary involvement in multiple myeloma. Interstitial lung disease as pulmonary manifestation of multiple myeloma is even rarer; only isolated cases with histological proofs have been reported in the literature. PMID:26788357

Cerebral venous thrombosis (CVT) is a rare origin of stroke, the clinical presentation and etiologies vary. The prognosis is shown to be better than arterial thrombosis. Magnetic Resonance Imaging (MRI) and MR Venograpgy (MRV) are currently important tools for the diagnosis. We studied 30 cases of CVT diagnosed in the department of neurology at the University Hospital of Fez (Morocco). Patients diagnosed with CVT signs between January 2003 and October 2007 were included in the study. Cerebral CT-scan was performed in 27 cases (90%) while the MRI examination was done in 18 patients (67%); and most patients (90%) received anticoagulant therapy. The mean age of our patients was of 29 years (age range between 18 days and 65 years). A female predominance was observed (70%). The clinical presentation of patients was dominated by: headache in 24 cases (80%), motor and sensory disability in 15 cases (50%), seizures in 10 cases (33%), consciousness disorder in 10 cases (33%). CVT was associated to post-partum in 10 cases (33%), infectious origin in 8 cases (26%), Behçet disease in 2 cases (7%), pulmonary carcinoma in 1 case, thrombocytemia in 1 case and idiopathic in 7 cases (23%). The evolution was good in 20 cases (67%), minor squelaes were observed in 6 patients (20%), while major squelaes were observed in 2 cases. Two cases of death were registered. The CVT is a pathology of good prognosis once the diagnosis is promptly established and early heparin treatment initiated. PMID:25317229

Soil is a non-renewable resource with fundamental functions like filtering (e.g. water), storing (e.g. carbon), transforming (e.g. nutrients) and buffering (e.g. contamination). Degradation of soils is meanwhile not only to scientists a well known fact, also decision makers in politics have accepted this as a serious problem for several environmental aspects. National and international authorities have already worked out preservation and restoration strategies for soil degradation, though it is still work of active research how to put these strategies into real practice. But common to all strategies the description of soil state and dynamics is required as a base step. This includes collecting information from soils with methods ranging from direct soil sampling to remote applications. In an intermediate scale mobile geophysical methods are applied with the advantage of fast working progress but disadvantage of site specific calibration and interpretation issues. In the framework of the iSOIL project we present here some case studies for soil mapping performed using multiple geophysical methods. We will present examples of combined field measurements with EMI-, GPR-, magnetic and gammaspectrometric techniques carried out with the mobile multi-sensor-system of Kiel University (GER). Depending on soil type and actual environmental conditions, different methods show a different quality of information. With application of diverse methods we want to figure out, which methods or combination of methods will give the most reliable information concerning soil state and properties. To investigate the influence of varying material we performed mapping campaigns on field sites with sandy, loamy and loessy soils. Classification of measured or derived attributes show not only the lateral variability but also gives hints to a variation in the vertical distribution of soil material. For all soils of course soil water content can be a critical factor concerning a succesful

Case studies have been the cornerstone of many discoveries in neurology and continue to be an indispensable source of knowledge. Attaching a name, face, and story to the study of neurological disorders makes them more “real” and memorable. This article describes the value of the case study methodology and its advantages as a pedagogical approach. It also illustrates how the seminal case of H.M. can be used to highlight the advantages and disadvantages of the case study methodology. Three exercises are described for incorporating case studies into neuroscience courses. The first exercise requires students to conduct a literature review regarding their assigned case and then design an experiment to address a lingering question regarding that neurological disorder. Survey results of 90 students provide quantitative and qualitative support for this approach. The vast majority of students indicated this exercise was a valuable learning experience; sparked interest in the topic and in biopsychology; increased their knowledge and stimulated critical thinking. The second exercise discusses how students might conduct their own case studies. The third exercise emphasizes the use of case studies as a platform to examine competing hypotheses regarding neurological conditions and their treatment. A table listing case studies appropriate for undergraduate neuroscience courses is included. Cases are categorized by the type of neurological disorder and notes regarding the nature of and content of each case are provided. PMID:23493154

We report 11 patients with laryngeal tuberculosis seen in our hospital, January 1990 to July 2000. Eight were men and all cases presented with dysphonia and/or disphagia. In 8 pulmonary tuberculosis was associated. Mycobacterium tuberculosis was isolated from the sputum in 7 patients. Granulomatous laryngitis was demonstrated in the eight patients with laryngeal biopsy. The evolution with medical treatment was favourable in all patients.

Do your students believe that the physics only works in your classroom or laboratory? Or do they see that physics underlies their everyday experience? Case studies in physics help students connect physics principles to their everyday experience. For decades, case studies have been used to teach law, medicine and biology, but they are rarely used in physics. I am working on a calculus-based physics textbook for scientists and engineers. Case studies are woven into each chapter. Stop by and get a case study to test out in your classroom. I would love to get your feedback.

Reverse case study is a collaborative, innovative, active learning strategy that nurse educators can use in the classroom. Groups of students develop a case study and a care plan from a list of medications and a short two- to three-sentence scenario. The students apply the nursing process to thoroughly develop a complete case study written as a concept map. The strategy builds on previous learned information and applies the information to new content, thus promoting critical thinking and problem solving. Reverse case study has been used in both associate and baccalaureate nursing degree theory courses to generate discussion and assist students in thinking like a nurse.

The Isakower phenomenon is a situation in which an individual typically experiences perceptions of enlargement or thickening, altered states of consciousness, sensations of floating, and impressions of the emergence and disappearance of an oral mass. This paper defines the phenomenon, reviews the literature, and describes a case in which a patient experienced it. The patient manifested the phenomenon symptomatically in the aftermath of a toxic state, and the elements were analysed for several years. There was support for Isakower's original thesis that the regressive states serve to defend against threatening incestuous fantasies. However, the Isakower phenomenon in this patient was the result of a multiplicity of determinants, largely defensive, involving many developmental levels.

Pityriasis amiantacea was first described in 1832. The disease may be secondary to any skin condition that primarily affects the scalp, including seborrheic dermatitis. Its pathogenesis remains uncertain. We aim to analyze the epidemiological and clinical profiles of patients with pityriasis amiantacea to better understand treatment responses. We identified seven cases of pityriasis amiantacea and a female predominance in a sample of 63 pediatric patients with seborrheic dermatitis followed for an average of 20.4 months. We reported a mean age of 5.9 years. Five patients were female, with a mean age of 9 years. All patients were successfully treated with topic ketoconazole. PMID:27828657

Pilonidal sinus (PNS) occurs in the cleavage between the buttocks (natal cleft) and can cause discomfort, embarrassment and absence from work for thousands of young people (mostly men) annually. The incidence of the disease is calculated to be 26 per 100,000 people. It occurs 2.2 times more often in men than in women. Age at presentation is 21 years for men and 19 years for women this case report describes a 22-year-old man with pilonidal sinus who was treated with ksharasutra. PMID:21170212

Sturge-Weber syndrome (SWS) is a rare, sporadic, progressive, congenital syndrome. In its complete trisymptomatic form, SWS is physically characterized by port-wine stains over the trigeminal area, leptomeningeal angiomas usually over the parieto-occipital region, and eye abnormalities. Clinical manifestation for infants with SWS depends on the affected organs, but can include seizures, mental retardation, and glaucoma. This article begins with a case presentation of an infant with SWS and then presents the etiology, embryology, pathophysiology, clinical presentation, management, and prognosis of SWS.
At a time when many managed care organizations increasingly shift costs to patients through tiered formularies and widening copay differentials, biologic agents represent a significant clinical and financial challenge unlikely to be managed optimally with tiered formularies and greater patient cost sharing. The information discussed in this article is intended for healthcare professionals involved with rheumatoid arthritis therapy, including but not limited to physicians in both the inpatient and outpatient setting, and for other managed care professionals, including medical directors, pharmacy directors, long-term care decision makers, nurses, pharmacists, and case managers.

Anejaculation is an uncommon clinical entity that may result from a variety of causes, both organic and psychological. Psychogenic anejaculation is influenced by relationship, behavioral, and psychological factors. We present a clinical case of situational anejaculation, which was managed with a combination of techniques that addressed these factors including changes in masturbatory technique, improved marital communication and quality, and reduction of anxiety using cognitive behavioral techniques. It is suggested that the standard techniques of sex therapy be modified and tailored to manage the specific problems of the individual patient. PMID:25035564

Regional estimates of cryptosporidiosis risks from drinking water exposure were developed and validated, accounting for AIDS status and age. We constructed a model with probability distributions and point estimates representing Cryptosporidium in tap water, tap water consumed per day (exposure characterization); dose response, illness given infection, prolonged illness given illness; and three conditional probabilities describing the likelihood of case detection by active surveillance (health effects characterization). The model predictions were combined with population data to derive expected case numbers and incidence rates per 100,000 population, by age and AIDS status, borough specific and for New York City overall in 2000 (risk characterization). They were compared with same-year surveillance data to evaluate predictive ability, assumed to represent true incidence of waterborne cryptosporidiosis. The predicted mean risks, similar to previously published estimates for this region, overpredicted observed incidence-most extensively when accounting for AIDS status. The results suggest that overprediction may be due to conservative parameters applied to both non-AIDS and AIDS populations, and that biological differences for children need to be incorporated. Interpretations are limited by the unknown accuracy of available surveillance data, in addition to variability and uncertainty of model predictions. The model appears sensitive to geographical differences in AIDS prevalence. The use of surveillance data for validation and model parameters pertinent to susceptibility are discussed.

Fulminant hepatic failure (FHF), also known as fulminant hepatitis, is a rare and extremely serious condition with a high mortality rate. Its rapid evolution and complexity in managing the treatment, creates the need to provide some immediate care by a team that specialises in intensive care. This acute decompensation is usually associated with other disorders, such as coagulopathy and hepatic encephalopathy, being responsible for major complications that can lead to organ failure. In our region the most common origin is unknown, followed by acute infection with hepatitis B. The treatment of this syndrome is based on the general measures applicable to any critically ill patient: treat the cause and early detection of extrahepatic complications, urgent liver transplantation being one of the alternatives with a better prognosis. This article presents a case report describing the monitoring of an Irish woman of 20 years who was transferred from a hospital in Ibiza to a hospital in Barcelona, with a suspected diagnosis of FHF. Following the conceptual model of Virginia Henderson, the collaborative problems and nursing diagnoses are described, presenting a care plan according to NANDA (North American Nursing Association), NIC (Nursing Intervention Classification), NOC (Nursing Outcomes Classification). This case helps to establish an individualised care plan that provides guidance to nurse professionals in critical patient care by increasing the knowledge of FHF.

A total of 271 measurements were conducted at 69 different sites including homes, hospitals, educational institutions and other public places to assess the exposure to radiofrequency emission from wireless local area networks (WLANs). Measurements were conducted at different distances from 40 to 10 m from the access points (APs) in real life conditions using Narda SRM-3000 selective radiation meter. Three measurements modes were considered at 1 m distance from the AP which are transmit mode, idle mode, and from the client card (laptop computer). All measurements were conducted indoor in the West Bank environment. Power density levels from WLAN systems were found to vary from 0.001 to ~1.9 μW cm-2 with an average of 0.12 μW cm-2. Maximum value found was in university environment, while the minimum was found in schools. For one measurement case where the AP was 20 cm far while transmitting large files, the measured power density reached a value of ~4.5 μW cm-2. This value is however 221 times below the general public exposure limit recommended by the International Commission on Non-Ionizing Radiation Protection, which was not exceeded in any case. Measurements of power density at 1 m around the laptop resulted in less exposure than the AP in both transmit and idle modes as well. Specific absorption rate for the head of the laptop user was estimated and found to vary from 0.1 to 2 mW/kg. The frequency distribution of measured power densities follows a log-normal distribution which is generally typical in the assessment of exposure resulting from sources of radiofrequency emissions.

Case-Control study design is a type of observational study. In this design, participants are selected for the study based on their outcome status. Thus, some participants have the outcome of interest (referred to as cases), whereas others do not have the outcome of interest (referred to as controls). The investigator then assesses the exposure in both these groups. The investigator should define the cases as specifically as possible. Sometimes, definition of a disease may be based on multiple criteria; thus, all these points should be explicitly stated in case definition. An important aspect of selecting a control is that they should be from the same 'study base' as that of the cases. We can select controls from a variety of groups. Some of them are: General population; relatives or friends; and hospital patients. Matching is often used in case-control control studies to ensure that the cases and controls are similar in certain characteristics, and it is a useful technique to increase the efficiency of the study. Case-Control studies can usually be conducted relatively faster and are inexpensive - particularly when compared with cohort studies (prospective). It is useful to study rare outcomes and outcomes with long latent periods. This design is not very useful to study rare exposures. Furthermore, they may also be prone to certain biases - selection bias and recall bias.

Here we describe the first documented case of congenital amusia in childhood. AS is a 10-year-old girl who was referred to us by her choir director for persisting difficulties in singing. We tested her with the child version of the Montreal Battery for the Evaluation of Amusia (MBEA) which confirmed AS's severe problems with melodic and rhythmic discrimination and memory for melodies. The disorder appears to be limited to music since her audiometry as well as her intellectual and language skills are normal. Furthermore, the musical disorder is associated to a severe deficit in detecting small pitch changes. The electrical brain responses point to an anomaly in the early stages of auditory processing, such as reflected by an abnormal mismatch negativity (MMN) response to small pitch changes. In singing, AS makes more pitch than time errors. Thus, despite frequent and regular musical practice, AS's profile is similar to the adult form of congenital amusia.
The port of Rotterdam, The Netherlands, is the world's largest container port. In 2006, one of these containers caused a chemical incident. Methylbromide is used in some countries as a pesticide for the fumigation of maritime containers. Because of an insufficiently performed detoxification, this insecticide intoxicated several employees and some of the ambulance crew and Mobile Medical Team (MMT). The victims displayed symptoms of sore throat, irritated eyes, and hypersalivation. One of the victims suffered from multiple epileptic seizures. Two victims were admitted to the intensive care unit for respiratory support. Three other employees showed milder symptoms and received supportive care but were not admitted to the hospital. This complicated case shows that the safety of the ambulance crew and MMT must be guaranteed. It also demonstrates that healthcare providers cannot always oversee the accident scene and that there are some pitfalls that are almost impossible to prevent.

Benzocaine is a widely used topical anaesthetic and has been reported to cause toxic methaemoglobinaemia in otherwise healthy individuals with no predisposing risk factors. This article reports on a rare case of benzocaine-induced methaemoglobinaemia following adenotonsillectomy in a 5-year-old girl. Topical benzocaine was applied orally for the relief of postoperative wound pain on the eighth postoperative day. Two hours after application, generalized cyanosis, mild dyspnoea and some degree of agitation developed. The methaemoglobin level was 38.5%. Treatment with methylene blue was initiated immediately. Symptoms completely disappeared 4 hours after initiation of methylene blue therapy. The further course was uneventful. Therefore, all health professionals should be aware that topical anaesthetics after surgery can induce methaemoglobinaemia in children, even after a prolonged interval, and especially when applied on wound surfaces.

Acute normovolaemic haemodilution (ANH) is a technique used to preserve a patient's owns red blood cells and reduce the incidence of heterogeneous blood transfusion. This paper describes the use of the technique in a dog and a kitten. A significant benefit of ANH can be shown in the canine case presented. The dog lost 1800 ml of blood during surgery but the haematocrit was only reduced to 33% 6 hours after the end of surgery. The kitten, however, did not benefit from ANH. It lost a small volume of blood during surgery and developed complications. This paper also describes some of the potential complications that may occur. To the best of my knowledge, this is the 1st clinical description of ANH in a dog and a cat.

A 67-year-old man presented with a 7-month history of insidiously progressive chorea, ataxia, and vertigo. Neurologic examination revealed deficits referable to the basal nuclei, cerebellar vermis, and vestibular nuclei. Small-cell lung cancer was diagnosed by fine-needle biopsy of a parahilar mass. After chemotherapy, the patient's chorea worsened. Anti-Hu antibodies were present in serum and cerebrospinal fluid. Microscopic examination of the brain at autopsy revealed diffuse perivascular lymphocytic infiltrates, microglial activation, and neuronophagia throughout the neuraxis, including the brainstem, cerebellum, lenticular nuclei, striatum, and cerebral cortex. Prominent loss of Purkinje cells was seen in the cerebellar vermis and hemispheres to a lesser degree. Chorea is extremely rare as a paraneoplastic manifestation of cancer. The florid presentation and the positive findings contrasted with an unremarkable MRI of the brain. This case illustrates the preeminence of symptoms and signs over negative MRI findings in paraneoplastic encephalitis. PMID:12084350

This unit provides an overview of the design and analysis of population-based case-control studies of genetic risk factors for complex disease. Considerations specific to genetic studies are emphasized. The unit reviews basic study designs differentiating case-control studies from others, presents different genetic association strategies (candidate gene, genome-wide association, and high-throughput sequencing), introduces basic methods of statistical analysis for case-control data and approaches to combining case-control studies, and discusses measures of association and impact. Admixed populations, controlling for confounding (including population stratification), consideration of multiple loci and environmental risk factors, and complementary analyses of haplotypes, genes, and pathways are briefly discussed. Readers are referred to basic texts on epidemiology for more details on general conduct of case-control studies.

Three cases of malignant transformation within spiradenoma are described. All of them occurred close to the elbow. In every case we found a benign component, characteristic of the spiradenoma, and a structure of carcinoma, which in some areas showed transition into the spiradenoma. In one case the structure of the spiradenocarcinoma resembled that of the spiradenoma, whereas in the remaining two cases adenocarcinoma was the malignant counterpart of the tumor. We performed immunohistochemical studies and revealed various intensities of expression of cytokeratins and epithelial membrane antigen and a dearth of S-100 protein, vimentin, and carcinoembryonic antigen in the examined cases of spiradenocarcinoma.

Nitrate concentration in groundwater is influenced by complex and interrelated variables, leading to great difficulty during the modeling process. The objectives of this study are (1) to evaluate the performance of two artificial intelligence (AI) techniques, namely artificial neural networks and support vector machine, in modeling groundwater nitrate concentration using scant input data, as well as (2) to assess the effect of data clustering as a pre-modeling technique on the developed models' performance. The AI models were developed using data from 22 municipal wells of the Gaza coastal aquifer in Palestine from 2000 to 2010. Results indicated high simulation performance, with the correlation coefficient and the mean average percentage error of the best model reaching 0.996 and 7 %, respectively. The variables that strongly influenced groundwater nitrate concentration were previous nitrate concentration, groundwater recharge, and on-ground nitrogen load of each land use land cover category in the well's vicinity. The results also demonstrated the merit of performing clustering of input data prior to the application of AI models. With their high performance and simplicity, the developed AI models can be effectively utilized to assess the effects of future management scenarios on groundwater nitrate concentration, leading to more reasonable groundwater resources management and decision-making.

The cost of building an Enterprise Data Warehouse Environment runs usually in millions of dollars and takes years to complete. Even bigger than cost is the risk that all the design and development of the Data Warehouse and Business Intelligence Environment may not bring the result expected by the user. This was the main incentive behind author's effort of laying down the foundation for new methodology called Data Warehouse Discovery . The foundation met with acceptance by some scientific groups on one hand and industry interest on the other. At that point, the author faced a major challenge. In order to get industry full acceptance as viable tool for the development and maintenance of a robust DW/BI environment, an actual implementation of the methodology in production was necessary. The DW/BI Strategy and Design Project that author was just conducting for the Canadian Federal Government was a perfect opportunity to propose and implement the methodology. This paper is presenting the conduct and results of that business case.

In April and May of 1979 an Anthrax epidemic broke out in the city of Sverdlovsk (now Ekaterinburg) in the former Soviet Union. Sixty-four people were reported to have died from the outbreak, although there is still debate concerning the actual number of victims. While Soviet officials initially attributed this outbreak to contaminated meat, the US Government maintained that the outbreak was due to a leakage from a biological weapons facility. We have created and implemented an undergraduate educational exercise based on the forensic analysis of this event. Students were provided case data of the victims, area satellite images and meteorological data. One goal of the exercise was for students to reconstruct the most probable scenario of events through valid inference based on the limited information and uncertainties associated with the data set. Another goal was to make students sensitive to issues of biological weapons and bioterrorism. The exercise was highly rated by students even before the events of September 11. There is a clear need to educate students, particularly in the sciences, to be aware of the signatures of terrorist activities. Evidence of terrorist activities is more likely to appear from unintended discoveries than from active intelligence gathering. We believe our national security can be enhanced by sensitizing those that monitor the natural environment to the signatures of terrorist activities through the types of educational exercises that we have developed.

Retina is the part of the eye suffering most damage from pharmaceutical molecules. Drug-induced retinopathies have been described but data are scarce and sometimes conflicting especially concerning its potential seriousness. The aim of this study was to investigate potential associations between drugs and retinal disorders using the French Pharmacovigilance data. We used the case/non-case method in the French PharmacoVigilance Database (FPVD) to identify drugs able to induce retinopathies. Cases were reports of retinal disorders in the FPVD between January 2008 and December 2012. Non-cases were all other reports during the same period. To assess the association between retinopathy and drug intake, we calculated the odds-ratio (OR) [with their 95% confidence intervals] for all drugs associated with at least 3 cases of retinopathy. Among the 123 687 adverse drug reactions recorded during the studied period, we identified 164 cases of retinal disorders. Significant associations were found for 11 drugs. The main therapeutic classes were antirhumatismals (hydroxychloroquine, chloroquine and etanercept: 18 cases), anti-infective (ribavirine, PEG-interferon-alfa-2a and cefuroxime: 16 cases) and antineoplastic drugs (imatinib and letrozole: 8 cases. Three other drugs were also found: raloxifene (5 cases), erythropoietin beta (4 cases) and ranibizumab (3 cases). Taking into account the limits of the methodology, our study confirmed the association between retinopathy and some expected drugs such as aminoquinolines, interferons, imatinib or ranibizumab. Other drugs like erythropoietin beta, cefuroxime, letrozole and etanercept were significantly associated with retinal disorders although this was not or poorly described in the literature. Thus, further prospective studies are necessary to confirm such associations.

Many wonder why there has been so little change in care quality, despite substantial quality improvement efforts. Questioning why current approaches are not making true changes draws attention to the organization as a source of answers. We bring together the case study method and complexity science to suggest new ways to study health care organizations. The case study provides a method for studying systems. Complexity theory suggests that keys to understanding the system are contained in patterns of relationships and interactions among the system’s agents. We propose some of the “objects” of study that are implicated by complexity theory and discuss how studying these using case methods may provide useful maps of the system. We offer complexity theory, partnered with case study method, as a place to begin the daunting task of studying a system as an integrated whole. PMID:15802542

Case study research is a comprehensive method that incorporates multiple sources of data to provide detailed accounts of complex research phenomena in real-life contexts. However, current models of case study research do not particularly distinguish the unique contribution observation data can make. Observation methods have the potential to reach beyond other methods that rely largely or solely on self-report. This article describes the distinctive characteristics of case study observational research, a modified form of Yin's 2014 model of case study research the authors used in a study exploring interprofessional collaboration in primary care. In this approach, observation data are positioned as the central component of the research design. Case study observational research offers a promising approach for researchers in a wide range of health care settings seeking more complete understandings of complex topics, where contextual influences are of primary concern. Future research is needed to refine and evaluate the approach.

In 1992, Kiss Cathcart Anders Architects performed a study for NREL on Building-Integrated Photovoltaics (BIPV) issues as seen from the perspective of the building community. In general, the purpose of the study was to list major issues and potential applications; by it`s nature it asked more questions than it answered. This second phase study was to produce quantitative data on the performance of specific BIPV systems. Only roof systems are evaluated. The energy performance, construction cost and simple payback for five different BIPV roof options are evaluated in six different locations: Oakland, New York, Miami, Phoenix, Chicago, and Cincinnati. The roof options evaluated include the following: single-glazed PV roof using glass-substrate PVs; double-glazed PV roof with insulating PV modules; ballasted roof-mounted system; sawtooth light monitor roof with indirect north daylighting; sawtooth roof with north light and active heat recovery.

A joint study has been conducted by NASA and Army installations collocated in a dense forest in southwestern Mississippi in order to determine the technical and economic feasibility of using wood waste as a renewable energy source. The study has shown that, with proper forest management, the timber on government lands could eventually support the total energy requirements of 832 billion Btu/yr. Analysis of the current conversion technologies indicates that the direct combustion spreader stoker approach is the best demonstrated technology for this specific application. The economics of the individual powerplants reveal them as attractive alternatives to fossil fueled plants. Environmental aspects are also discussed.

Land degradation by soil erosion is a socioeconomic and environmental problem facing many developing countries. Application of stonewall terraces for soil moisture conservation is vital to reducing the environmental impacts of this phenomenon. To this end, a field plot experiment was conducted in the study area along with the use of a closed-ended questionnaire. The object of the experiment was to study the socioeconomic impacts of soil erosion on local farmers and their adoption of the stonewall terrace technique. The study showed a higher net profit in areas that had implemented terrace conservation practices than in areas that had not (i.e., 3.5 to 6 times higher net profit). Correlation analysis indicated that the farmers' perceptions, land ownership, and geomorphology were significantly related to the farmers' incentives and willingness to adopt terraces as soil conservation measures (P < 0.05), although the correlations were negative. Smallholder farmers (52% of the interviewed farmers) were involved in the sale of the agricultural land for urban uses, largely because of the high price and immediate returns offered. However, the associated land use changes warrant greater involvement of both the private and public sectors. This cooperation may be accomplished through the introduction of a long-term agricultural loan system and the development of proper legislation accompanied by a comprehensive and durable infrastructure and service system with the goal of reducing the negative impact of land use changes and encouraging sustainable use of resources.

This manuscript provides a review of the clinical case study within the field of psychoanalytic and psychodynamic treatment. The method has been contested for methodological reasons and because it would contribute to theoretical pluralism in the field. We summarize how the case study method is being applied in different schools of psychoanalysis, and we clarify the unique strengths of this method and areas for improvement. Finally, based on the literature and on our own experience with case study research, we come to formulate nine guidelines for future case study authors: (1) basic information to include, (2) clarification of the motivation to select a particular patient, (3) information about informed consent and disguise, (4) patient background and context of referral or self-referral, (5) patient's narrative, therapist's observations and interpretations, (6) interpretative heuristics, (7) reflexivity and counter-transference, (8) leaving room for interpretation, and (9) answering the research question, and comparison with other cases.

The hallmark of an open-ended case study is the possibility of multiple outcomes to the problem at hand. This adds to the realism, provokes higher-order thought, and attracts many instructors to case analysis. Yet, there are circumstances in which a closed-ended approach, having a single correct answer, may be preferred. In this article, the…
