    If the signals being sought in search for extraterrestrial intelligence (SETI) programs exist but are brief (for example, they are produced intermittently to conserve energy), then it is essential to know when these signals will arrive at the Earth. Different types of transmitter/receiver synchronization schemes are possible, which vary in the relative amount of effort required by the transmitter and the receiver. The case is made for a scheme that is extremely simple for the receiver: Make observations of a target when it is at maximum angular distance from the Sun (i.e., "opposition"). This strategy requires that the transmitter has accurate knowledge of the distance and proper motion of the Sun and the orbit of the Earth. It is anticipated that within the next 10-20 years it will be possible to detect directly nearby extrasolar planets of approximately terrestrial mass. Since extraterrestrial transmitters are expected to have significantly more advanced technology, it is not unreasonable to expect that they would be able to detect the presence of the Earth and measure its orbit at even greater distances. This strategy is simple to implement, and opposition is also typically the time when observations are easiest to make. Limited opposition surveys contained in a number of all-sky surveys have already been performed. However, full-sky opposition surveys are best suited to detectors with very large fields of view.

    Full Text Available Synchronous gynecological cancers are rarely described. Those cases account for approximately up to 6% of female genital tract malignancies. The presence of synchronous endometrial adenocarcinoma and gynecological tract neoplasia is rare – the most commonly described is synchronous adenocarcinoma and endometrial ovarian cancer (accounting for 15-20% of ovarian neoplasia and 5% of endometrial cancers. Concomitant uterine carcinosarcoma and ovarian cancer, or endometrial adenocarcinoma are extremely rare. Up till now, only 3 cases of synchronous adenocarcinoma and leiomyosarcoma were described. In the present study a case of 60-year-old woman diagnosed with synchronous endometrial adenocarcinoma and leiomyosarcoma uteri is described. As the preoperative evaluation revealed endometrial adenocarcinoma G2 with intermediate-risk of lymph node metastasis and synchronous leiomyosarcoma G3, total hysterectomy with bilateral salpingo-oophorectomy and systemic lymphadenectomy was performed showing no lymphatic involvement. In the postoperative evaluation the patient was qualified to adenocarcinoma low recurrence-risk group (adenocarcinoma G1 with no LVSI, FIGO IA – no further radiotherapy was required. However, as synchronous leiomyosarcoma G3 was diagnosed, we decided to refer the patient for adjuvant chemotherapy. Contemporary recommendation on the diagnosis and treatment of uterine carcinomas, especially uterine leiomyosarcomas, is also described in this paper. The presented case showed that diagnosis and treatment of women with uterine tumors should be individualized as in the same case an extremely rare cancer type can be present which, consequently, changes the treatment regimen and prognosis.

    Objective. There is a current debate whether multicentric osteosarcoma represents synchronous multiple primary osteosarcomas or metastatic disease. The purpose of this report is to evaluate the etiology, presentation, and classification of this entity. Design and patients. Six patients ranging in age from 7 to 29 years were studied. The clinical, radiographic, and pathologic findings are reported. In addition, a review of the literature was undertaken. Results. The clinical courses of our six patients as well as a review of the literature suggest that multicentric osteosarcoma represent one extreme of a continuous scale of metastatic osteosarcoma rather than multiple synchronous primary tumors. The presentation is unusual and the clinical behavior distinctive, but the mechanism of spread remains the same: blood-borne and lymphatic-borne. Conclusions. Our experience with these six patients supports the concept in the recent literature that synchronous osteosarcoma is one extreme of the spectrum of metastatic osteosarcoma. Its unique features are: (1) multiple radiodense lesions that present simultaneously with or without pulmonary metastases; (2) a single ''dominant'' lesion with multiple smaller lesions; and (3) a uniformly rapid, fatal prognosis. Osteosarcoma should be regarded as a metastatic disease, even when only a single primary lesion is found at the initial presentation. (orig.)

    Synchronous multiple primary malignancies in the female genital tract are infrequent. From 50 to 70% of them corresponds to synchronous cancers of the endometrium and ovary. To our knowledge, this is only the third case report in the international literature of three concurrent gynaecological cancers of epithelial origin. A case is presented, as well as a literature review due to the infrequency of its diagnosis and the lack of information on the subject. A 49-year-old woman, with previous gynaecological history of ovarian endometriosis. She underwent a hysterectomy and bilateral oophorectomy, as she had been diagnosed with endometrial hyperplasia with atypia. The final histopathology reported synchronous ovarian, Fallopian tube, and endometrial cancer. An extension study and complete surgical staging was performed, both being negative. She received adjuvant treatment of chemotherapy and radiotherapy. She is currently free of disease. The aetiology is uncertain. There is controversy relating to increased susceptibility of synchronous neoplasms to pelvic endometriosis and inherited genetic syndromes. Its diagnosis needs to differentiate them from metastatic disease. Additionally, they are problematical from a clinical, diagnostic, therapeutic, and prognostic point of view. The presentation of more cases of triple synchronous cancers is necessary for a complete adjuvant and surgical treatment. Copyright © 2015 Academia Mexicana de Cirugía A.C.

    Primary cancer may occur synchronously in two different organs. We present an example of pathologically proven, coexistent renal and colony double malignant tumors. A 59 year old man, was admitted to the Institute of Oncology due to left renal lesion, discovered during a routine abdominal ultrasound examination. The CT exam was performed before surgery. The CT scans reveled a second abnormality, presenting irregular shaped and thickened to 20 mm intestinal wall within a patient's large bowel. As a next diagnostic step a CT-colonoscopy was undertaken, which confirmed the presence of an exophytic sigmoid lesion, eccentrically affecting the colonic wall and protruding into the lumen moderately narrowing it, placed about 50 cm from the external rectal sphincter. Patient underwent simultaneous radical left nephrectomy and sigmoidectomy. Both tumors were confirmed in pathologic evaluation, reveling renal clear cell carcinoma (Fuhrman G II) and colonic adenocarcinoma (Astler-Coller B2). Preoperative careful imaging studies reveled neoplastic tumors in two different organs, allowing for radical resection at the same surgical procedure. (author)

    This paper develops an off-policy reinforcement learning (RL) algorithm to solve optimal synchronization of multiagent systems. This is accomplished by using the framework of graphical games. In contrast to traditional control protocols, which require complete knowledge of agent dynamics, the proposed off-policy RL algorithm is a model-free approach, in that it solves the optimal synchronization problem without knowing any knowledge of the agent dynamics. A prescribed control policy, called behavior policy, is applied to each agent to generate and collect data for learning. An off-policy Bellman equation is derived for each agent to learn the value function for the policy under evaluation, called target policy, and find an improved policy, simultaneously. Actor and critic neural networks along with least-square approach are employed to approximate target control policies and value functions using the data generated by applying prescribed behavior policies. Finally, an off-policy RL algorithm is presented that is implemented in real time and gives the approximate optimal control policy for each agent using only measured data. It is shown that the optimal distributed policies found by the proposed algorithm satisfy the global Nash equilibrium and synchronize all agents to the leader. Simulation results illustrate the effectiveness of the proposed method.

  8. Synchronous GISTs associated with multiple sporadic tumors: a case report

    2017-08-01

    Full Text Available Gastrointestinal stromal tumors (GISTs are rare neoplasms, but they also represent the most common mesenchymal tumors of the gastrointestinal tract originating from the cell of Cajal. GIST incidence ranges around 1% of all gastrointestinal malignancies. Approximately 5% of all GISTs have a hereditary etiology. The remaining 95% of GISTs are considered sporadic events, with up to 75% of cases driven by a constitutional activation of the c-KIT proto-oncogene. GISTs are generally solitary lesions. Nonetheless, multiple sporadic GISTs can occur and present as synchronous or metachronous tumors, usually associated with familial GIST. Here, we report a case of primary prostate and lung tumors associated with gastric and small bowel GISTs, unrelated to any known hereditary syndrome. Also, in the case we describe, the prostatic tumor came before the GISTs, while the lung tumor occurred later in time and led to pulmonary lobectomy plus lymphoadenectomy, with a diagnosis of nonsmall cell lung cancer. With the exception of a slight difference in lymphoid infiltration, the abdominal and gastric GIST nodules shared the same proliferative MIB1 index and mitotic count. However, the genetic analysis revealed that the gastric GIST and abdominal tumors were characterized by two different c-KIT mutations. This molecular heterogeneity supported the hypothesis of two different synchronous GISTs arising from stomach and ileum. At present, the patient is disease free and has already completed the third year of adjuvant therapy with imatinib. This case supports the importance of the analysis of c-KIT mutational status to distinguish metastases from synchronous multicentric GISTs, with relevant implications in therapeutic decisions, as well as the importance of a dedicated multidisciplinary team and of a radiological follow-up after the diagnosis of a primary GIST, to discover a relapse of the GIST or, possibly, additional malignancies.

    Quantitative analysis of the events of synchronous references in the research papers followed throughout the publishing career of an individual scientist revealed interesting highlights on the knowledge-generating-system. In the case study of Homi Jehangir Bhabha, the first quinquennium and fifth quinquennium of his research career had low self-references; the third quinquennium and the fourth quinquennium had moderate self-references; whereas the second quinquennium had the highest number of self-references. The two major clusters of self-references occurring during the second and third quinquenniums were indicators of active periods of knowledge-generating and faster communications. (author)

    We report a case of synchronous symmetrical osteoid osteoma of tibia which was atypical in its appearance on imaging. Our patient was a 30-year-old woman presented with 2 years history of bilateral leg pain more on the right side. The pain was more during night and relieved on taking salicylates. Laboratory investigations were within normal limits. Radiographs and computed tomography revealed bilateral focal irregular cortical sclerosis with narrowing of medullary canal of mid tibia. The lesion on right side was excised enbloc followed by the lesion on left side 3 months later and histologically confirmed as osteoid osteoma. Initially, we thought it was stress fracture or subacute osteomyelitis but it was in fact histopathology which showed osteoid osteoma. Patient was completely asymptomatic postoperatively.

    Full Text Available Synchronous bilateral upper urinary tract urothelial cancer (UTUC is a very rare form of urothelial cancer. In patients with high-risk unilateral UTUC, radical nephroureterectomy (RNU is the gold standard treatment. However, there is no consensus on the treatment for synchronous bilateral UTUC. Evaluation of the patient and the tumor is recommended. Bilateral nephron-sparing surgery (NSS was performed on a 53-year-old patient who presented with high-risk synchronous bilateral UTUC, and the outcome was reported.

    The aim of this research is to resolve high inventory problem at RBI Cileungsi warehouse due to the imbalance flow between production outputs compared to sales realization. As an attempt to synchronize these flows we will analyse sales realization data as a representation of customer demand and determine the optimal inventory policy to meet them. Analysis will be conducted to three SKUs which had high investment value. P inventory models will be implemented and then evaluated against current condition to determine their financial benefit. Evaluation suggested that the proposed policy would give total savings of Rp. 780,667,909.97 for the first SKU, Rp. 35,361,072.53 for the second SKU and Rp. 136,729,725.19 for the third SKU. These results lead to the conclusions that the proposed policy should be further considered to be applied to other SKUs.

  17. Synchronicity from Synchronized Chaos

    Directory of Open Access Journals (Sweden)

    Gregory S. Duane

    2015-03-01

    Full Text Available The synchronization of loosely-coupled chaotic oscillators, a phenomenon investigated intensively for the last two decades, may realize the philosophical concept of “synchronicity”—the commonplace notion that related eventsmysteriously occur at the same time. When extended to continuous media and/or large discrete arrays, and when general (non-identical correspondences are considered between states, intermittent synchronous relationships indeed become ubiquitous. Meaningful synchronicity follows naturally if meaningful events are identified with coherent structures, defined by internal synchronization between remote degrees of freedom; a condition that has been posited as necessary for synchronizability with an external system. The important case of synchronization between mind and matter is realized if mind is analogized to a computer model, synchronizing with a sporadically observed system, as in meteorological data assimilation. Evidence for the ubiquity of synchronization is reviewed along with recent proposals that: (1 synchronization of different models of the same objective process may be an expeditious route to improved computational modeling and may also describe the functioning of conscious brains; and (2 the nonlocality in quantum phenomena implied by Bell’s theorem may be explained in a variety of deterministic (hidden variable interpretations if the quantum world resides on a generalized synchronization “manifold”.

    2002-04-01

    We study the synchronization between left and right hemisphere rat electroencephalographic (EEG) channels by using various synchronization measures, namely nonlinear interdependences, phase synchronizations, mutual information, cross correlation, and the coherence function. In passing we show a close relation between two recently proposed phase synchronization measures and we extend the definition of one of them. In three typical examples we observe that except mutual information, all these measures give a useful quantification that is hard to be guessed beforehand from the raw data. Despite their differences, results are qualitatively the same. Therefore, we claim that the applied measures are valuable for the study of synchronization in real data. Moreover, in the particular case of EEG signals their use as complementary variables could be of clinical relevance.

    Synchronous bilateral breast cancer is extremely rare in men and has not, up to date, been reported in Korea. A 54-year-old man presented with a palpable mass in the right breast. The right nipple was retracted and bilateral axillary accessory breasts and nipples were present. On physical examination, a 2 cm-sized mass was palpated directly under the right nipple, and, with squeezing, bloody discharge developed in a single duct of the left nipple. There was no palpable mass in the left breast, and axillary lymph nodes were not palpable. Physical examination of external genitalia revealed a unilateral undescended testis on the left side. Synchronous bilateral breast cancer was diagnosed using mammography, ultrasonography, and core-needle biopsy. Histopathological examination revealed invasive ductal carcinoma in the right breast and ductal carcinoma in situ in the left breast. Bilateral total mastectomy, sentinel lymph node biopsy, and excision of accessory breasts in the axilla were performed.

  2. Towards a diachronic-synchronic view of future communication policies in Africa.

    Science.gov (United States)

    Wilson, D

    1989-01-01

    Democratic communication policy Africa cannot be exploited by nations that have a technological edge. Traditional, indigenous systems have to be analyzed by a diachronic-synchronic study to establish more effective communication systems for Africa. It is proposed in this diachronic- synchronic view that communication is a cultural transaction and transmission taking place over time. Old processes are synchronized with modern technology resulting in the closure of the cultural gap between traditional and modern societies. Traditional communication processes have been ignored for too long and communication as an industry has become an elite enterprise boasting expensive gadgets (television and radio, newspapers and magazines). Communication is culture, since it is a manifestation of the cultural norms of society. This monopolistic pattern of cultural or media imperialism is pervasive in the Third World. Communication theory is a multidisciplinary field which strongly reflects the music, art, religion, etc. of the society. The communication of religion has become a big cultural activity worldwide, and televangelism is a significant feature of it, although it strictly controlled in Nigeria despite the pervasiveness of religion in society. The traditional communication system consists of the village council of elders and chiefs and the gongman as a broadcaster or reporter. Modern communication systems utilize television, satellite systems, and computers. These powerful instruments, however, have become liabilities in Third World countries. Dominating powers sell these instruments of power and culture to a people who pay for the equipment by foreign loans. A very grave communication problem in Africa is the low literacy rate and the preeminence of foreign languages as the only medium for reaching majority of the literate public. The culture of the poorer nations is often distorted. Exhibition of Africa culture is rare, and Western culture is transmitted to poor nations

    Acute appendicitis and acute cholecystitis are among the most common diagnoses that general surgeons operate on. However, it is rarely described in its synchronous form. A 43 year-old woman attending the clinic for right upper quadrant pain of 11 days duration. The patient refers to intermittent radiating pain in the right side, with positive Murphy, tachycardia, and fever. The laboratory results showed white cells 16,200/mm(3), glucose 345 mg/dl, abnormal liver function tests. Acute cholecystitis was reported with ultrasound. A Masson-type incision was made, noting an enlarged pyogenic gallbladder with thickened walls, sub-hepatic abscess of approximately 300 ml, greenish-yellow colour, and foetid. An anterograde subtotal cholecystectomy is performed due to difficulty in identifying elements of Calot triangle due to the inflammatory process, opening it and extracting stones. The right iliac fossa is reviewed, finding a plastron and a sub-serous retrocaecal appendix perforated in its middle third with free fecalith and an abscess in the pelvic cavity. An anterograde appendectomy was performed and the patient progressed satisfactorily, later being discharged due to improvement. In this patient, with a history of recurrent episodes of gallbladder pain and disseminated acute abdominal pain without peritoneal irritation, clinical suspicion was exacerbated cholecystitis with probable empyema of the gallbladder. Open surgery approach for this patient allowed access to both the appendix and gallbladder in order to perform a complete exploration of the abdominal cavity. The synchronous presentation of cholecystolithiasis and complicated appendicitis has not been reported in the literature. Copyright © 2015 Academia Mexicana de Cirugía A.C.

    Multiple primary lung cancer may present in synchronous or metachronous form. Synchronous multiple primary lung cancer is defined as multiple lung lesions that develop at the same time, whereas metachronous multiple primary lung cancer describes multiple lung lesions that develop at different times, typically following treatment of the primary lung cancer. Patients with previously treated lung cancer are at risk for developing metachronous lung cancer, but with the success of computed tomography and positron emission tomography, the ability to detect both synchronous and metachronous lung cancer has increased. We present a case of a 63-year-old Hispanic man who came to our hospital for evaluation of chest pain, dry cough, and weight loss. He had recently been diagnosed with adenocarcinoma in the right upper lobe, with a poorly differentiated carcinoma favoring squamous cell cancer based on bronchoalveolar lavage of the right lower lobe for which treatment was started. Later, bronchoscopy incidentally revealed the patient to have an endobronchial lesion that turned out to be mixed small and large cell neuroendocrine lung cancer. Our patient had triple synchronous primary lung cancers that histologically were variant primary cancers. Triple synchronous primary lung cancer management continues to be a challenge. Our patient's case suggests that multiple primary lung cancers may still occur at a greater rate than can be detected by high-resolution computed tomography.

    Full Text Available Rhabdomyosarcoma is the commonest soft tissue sarcoma in both children and adolescents representing 40% of such tumours in North America and more than 50% in Africa. The involvement of the paratesticular tissue, testis and the kidney are generally rare and more so when it is occurring synchronously. We present a case of 22 year old male with inguinoscrotal swelling, fever and abdominal distention who was diagnosed as having obstructed left inguinoscrotal hernia and a right renal mass. The patient had surgery, and a diagnosis of synchronous rhabdomyosarcoma of the left testis, paratesticular tissue and right kidney was made by histology and immunohistochemistry.

    Full Text Available Cellular angiofibroma is a rare benign tumor which is found in the vulvovaginal or inguinoscrotal region. To the best of our knowledge, there have been no reports that describe two cellular angiofibromas on the same side of the scrotum. Here, we report the case of an 89-year-old male patient with two scrotal tumors which were proven to be cellular angiofibromas after the biopsy specimen was examined. The tumor markers were CD34 (+, focally positive for S-100, actin (−, desmin (−, estrogen receptor (−, progesterone receptor (−, beta-catenin (−, CD99 (−, and B-cell lymphoma 2 (−.

    Synchronous primary cancers of the endometrium and ovary are found in 5% of women with endometrial cancer and 10% of women with ovarian cancer. In the present case, a multigravid 46-year-old woman complained of lower abdominal pain and abdominal distension. She did not define abnormal uterine bleeding. Screening ultrasound revealed a papillary containing structure, irregular, cystic 16 x 15 x 10 cm right ovarian mass. Preoperative endometrial biopsy revealed endometrioid adenocarcinoma. Ascites sampling, radical hysterectomy, bilateral salpingo-oophorectomy, pelvic and paraaortic lymphadenectomy, omentectomy, appendectomy and cytologic sampling of the undersurface of the diaphragm were carried out. Intraoperative and histological examinations showed Stage IIIC papillary serous carcinoma and stage IC endometrioid adenocarcinoma. Synchronous genital tract neoplasms constitute a more common clinical problem than would generally be expected.

    Gastrointestinal stromal tumours (GISTs) are mesenchymal tumours of the digestive tract, derived from Cajal interstitial cells. Bone metastases are very rare, and there is no consensus regarding their treatment. Here, we present the unusual case of a 66-year-old man with a gastric GIST with synchronous bone and liver metastases, fully documented at the pathological and molecular levels with a KIT exon 11 mutation. After 9 months of imatinib, the scanner showed a 33% partial response of target lesions. We also review the literature and describe the characteristics, treatment, and outcome of all cases previously reported.

    Full Text Available Kidney transplantation is the most frequently performed organ transplant procedure in the world. The occurrence of malignant tumors is one of the well-known late complications of organ transplantation, which is induced by immunosuppressive therapy. In the vast majority of patients, kidney cancer occurs in the native organs; however, in a small percentage of cases, malignancies are found in the graft organ. The article describes a rare clinical case of a patient with synchronous cancer in the native and graft kidneys.

    Introduction: The patients with testicular germ cell tumors (TGT) present in the contralateral tumor development in approximately 3% of the cases. A small subset presenting with synchronous bilateral tumors (TBS). Case report: Patient is a 41-year study of infertility in who have performed bilateral testicular biopsies. Using ultrasound bilateral testicular nodules were diagnosed predominantly right. It performs a bilateral orchiectomy evidencing bilateral pure classic seminoma (T1 and T4). Staging the regional nodal involvement and distance rule and visceral with normal tumor markers. Receive adjuvant radiotherapy (3060 cGy) including inguinal lymph node chains, and pelvic and lumbo-aortic remaining free of disease at 33 months after surgery. Discussion: 85% of all bilateral TGT metachronous are presented as 15% synchronously. TBS represent less than 1% of the most representative series. In most cases they are seminomas and have been associated with infertility and history Family suggestive of genetic predisposition. Bilateral orchiectomy is local treatment of choice and subsequent planned strategy is according the loco-regional extension stressing the importance of hormone replacement and psychological support. Conclusions: In patients with a family history suggestive or infertile should be evaluated for TBS, especially if it carries a seminoma. the bilateral orchiectomy is local treatment of choice. We found no evidence seminomatous TBS have a worse prognosis compared with patients with unilateral or bilateral metachronous tumors of similar size lesional

    Full Text Available Abstract Introduction Primary non-Hodgkin's lymphoma of the small and large bowel presenting as a perforated viscus entity with peritonitis is extremely rare. A thorough literature review did not reveal any cases where primary lymphoma of the jejunum presented with perforation and peritonitis synchronously with primary lymphoma of the descending colon. Case presentation This report concerns a 64-year-old Caucasian woman admitted with severe abdominal pain and fever. An emergency laparotomy revealed a large mass with perforation in the proximal jejunum with intense mesenteric thickening and lymphadenopathy. The descending colon was edematous and covered with fibrinous exudate. Histopathological examination of the resected segment of jejunum revealed a T cell non-Hodgkin's lymphoma. On post-operative day 10, a computed tomography scan of our patient's abdomen and pelvis showed leakage of contrast into the pelvis. Re-exploration revealed perforation of the descending colon. The histopathology of the resected colon also showed T cell non-Hodgkin's lymphoma. Her post-operative course was complicated by acute renal and respiratory failure. The patient died on post-operative day 21. Conclusions Lymphoma of the small intestine has been reported to have a poor prognosis. The synchronous occurrence of lesions in the small intestine or colon is unusual, and impacts the prognosis adversely. Early diagnosis and treatment are important to improve the prognosis of bowel perforation in patients with non-Hodgkin's lymphoma.

    We report a mechanism capable of reducing (or increasing) stellar activity in binary stars, thereby potentially enhancing (or destroying) circumbinary habitability. In single stars, stellar aggression toward planetary atmospheres causes mass-loss, which is especially detrimental for late-type stars, because habitable zones are very close and activity is long lasting. In binaries, tidal rotational breaking reduces magnetic activity, thus reducing harmful levels of X-ray and ultraviolet (XUV) radiation and stellar mass-loss that are able to erode planetary atmospheres. We study this mechanism for all confirmed circumbinary (p-type) planets. We find that main sequence twins provide minimal flux variation and in some cases improved environments if the stars rotationally synchronize within the first Gyr. Solar-like twins, like Kepler 34 and Kepler 35, provide low habitable zone XUV fluxes and stellar wind pressures. These wide, moist, habitable zones may potentially support multiple habitable planets. Solar-type stars with lower mass companions, like Kepler 47, allow for protected planets over a wide range of secondary masses and binary periods. Kepler 38 and related binaries are marginal cases. Kepler 64 and analogs have dramatically reduced stellar aggression due to synchronization of the primary, but are limited by the short lifetime. Kepler 16 appears to be inhospitable to planets due to extreme XUV flux. These results have important implications for estimates of the number of stellar systems containing habitable planets in the Galaxy and allow for the selection of binaries suitable for follow-up searches for habitable planets.

    2015-04-01

    Full Text Available Central giant cell granuloma (CGCG is a benign proliferation of fibroblasts and multinucleated giant cells that almost exclusively occurs in the jaws. It commonly occurs in young adults showing a female predilection in the anterior mandible. Multifocal CGCGs in maxillofacial region are very rare and suggestive of systemic diseases such as hyperparathyroidism, an inherited syndrome such as Noonan-like multiple giant cell lesion syndrome or other disorders. Only 10 cases of multifocal CGCGs in the maxillofacial region without any concomitant systemic disease have been reported in the English literature. Here, we report an unusual case of 36 year-old female presented with non-syndromic synchronous, multifocal CGCGs in the left posterior mandible and left posterior maxilla without any concomitant systemic disease. Relevant literature is reviewed and the incidence, clinical features, radiological features, differential diagnosis and management of CGCGs are discussed.

    A case of synchronous triple urogenital cancer, which was comprised of renal cell carcinoma of the left kidney, transitional cell carcinoma of the urinary bladder, and adenocarcinoma of the prostate, is reported. A 72-year-old Japanese male patient was referred to our outpatient clinic with the complaint of asymptomatic hematuria. At that time, his serum of level of PSA was elevated to 20 ng/ml. Cystourethroscopy showed a papillary bladder tumor and coagula through the left urinary orifice. Ultrasonography, computed tomography and magnetic resonance imaging showed a mass lesion measuring about 6 cm by 5 cm in the left kidney. Angiography showed a hypervascular lesion measuring about 6 cm by 5 cm at the same site. Double cancer, consisting of renal cell carcinoma and transitional cell carcinoma of the urinary bladder, was suspected and we performed left total nephroureterectomy, hilar lymphadenectomy, and transurethral rection of the bladder tumor, one month later. At the same time, we performed a biopsy of the prostate. Histological diagnosis was renal cell carcinoma, clear cell carcinoma and transitional cell carcinoma of urinary bladder. Histological diagnosis of the prostate biopsy was moderately differentiated adenocarcinoma. Since this case fulfilled the criteria of Warren and Gates, it was classified as synchronous triple urogenital cancer. A review of the literature revealed 17 authentic cases of triple urogenital cancer, of which 14 and 10 cases were reported as a combination of renal cancer, bladder cancer and prostatic cancer, in the world and in Japan, respectively. Furthermore, he had been exposed to the atomic bomb explosion in Hiroshima in 1945. This carcinogenic precursor may be related to the development of the triple cancer. (author)

    Double cancers of the biliary tract system are rare. Most of these cancers are synchronous double cancers of the gall bladder and bile duct, associated with pancreaticobiliary maljunction (PBM). Synchronous double cancers of the extrahepatic bile duct without PBM are especially rare, and only 4 cases have been reported. A 78-year-old woman was admitted to our hospital for examination of hyperbilirubinemia and liver dysfunction. Contrast-enhanced abdominal computed tomography, Magnetic resonance cholangiopancreatography and endoscopic retrograde cholangiopancreatography revealed 2 stenotic regions in the common bile duct: at its junction with the cystic duct and in the distal bile duct. No findings suggested PBM, such as a markedly long common channel. The diagnosis based on endoscopic brush cytology from both stricture portions was adenocarcinoma. The patient had a pylorus-preserving pancreaticoduodenectomy with regional lymph node resection. Macroscopically, there were 2 stenotic regions at the cystic duct junction and in the distal bile duct. Microscopically, the tumor at the junction of the cystic duct was a well-to-moderately differentiated adenocarcinoma. On the other hand, the tumor of the distal bile duct was a poorly differentiated adenocarcinoma. There was no evidence of communication between these 2 cancers. Double cancers of the extrahepatic bile duct without PBM are very rare. Therefore, an accurate diagnosis prior to surgery is necessary. Furthermore, this rare condition seems to be associated with a poor prognosis. Copyright © 2018 The Authors. Published by Elsevier Ltd.. All rights reserved.

  5. Tutorial chat: a case study of synchronous communication in a learning environment

    Directory of Open Access Journals (Sweden)

    Malcolm Rutter

    2006-12-01

    Full Text Available This case study describes the use of a web-based synchronous chat application, run during computing tutorials. The chat room was moderated by a paid demonstrator, who assisted and encouraged students whenever possible. Most of the discussion was banter, which acted as a lubricant for relevant factual communication. Students were permitted a degree of anonymity, but nevertheless learned to treat the facility in a useful manner. The application and its mode of employment were found to be both motivating and supportive. Use was evaluated by questionnaire and an analysis of student input. As a result of the experience, it is suggested that abuse will certainly occur and may be minimised by technical improvements, but never eliminated. The Rogerian approach adopted was found to have transferred emphasis from teaching a topic to the learning of generic skills.

  6. A rare case with synchronous gastric gastrointestinal stromal tumor, pancreatic neuroendocrine tumor, and uterine leiomyoma.

    Although gastrointestinal stromal tumors (GISTs) are the most common mesenchymal tumors of the gastrointestinal tract, they comprise less than 1% of all gastrointestinal tumors. Neuroendocrine tumors (NET) of the gastro-enteropancreatic system are also rare, representing about 2% of all gastrointestinal neoplasms. Pancreatic localization of NET is extremely uncommon-these tumors are only 1-5% of all pancreatic cancers. We describe an unusual case with triple tumor localization-a gastric tumor, a formation in the pancreas, which involves the retroperitoneal space, and a uterine leiomyoma. The exact diagnosis was confirmed with immunohistochemical study after surgical treatment of the patient. Distal pancreatic resection, splenectomy, partial gastrectomy, omentectomy, and hysterectomy were performed. The histological examination proved an epithelioid type of gastric GIST. Immunostaining showed focal positive expression of c-kit and no mitotic figures per 50 HPF. Histology of the pancreatic and retroperitoneal formation proved a well-differentiated NET with origin from the islets of Langerhans. The immunohistochemical study demonstrated co-expression of chromogranin A and synaptophysin. This is the fourth case published so far of a patient with synchronous pancreatic NET and gastric GIST. The main objective of the study is to present a unique case because we have not found any reports for coexistence of the described three types of neoplasm, as in our patient, and we hope that it will be valuable in the future investigations about the genesis, diagnosis, and treatment of these types of tumors.

  7. Competition policy in patent cases and antitrust.

    Science.gov (United States)

    Sobel, Gerald

    2003-01-01

    The article that follows examines the competition policy reflected in the decisions of the Court of Appeals for the Federal Circuit in its patent cases. The court's views on this subject have been manifested most plainly in decisions that have transformed the law concerning infringement under the doctrine of equivalents and claim construction. In both categories, the court narrowed patent scope by reason of its desire to protect competitors. The article argues that the court's premise in prescribing narrower claim scope reflected an incomplete view of competition policy. The court's analysis overlooked the benefits to competition provided by patents, which stimulate inventions and their development. The article traces the development of antitrust jurisprudence and demonstrates how respect for the contribution of patents to competition and skepticism of free-riding has evolved, particularly beginning in the 1970s. The article draws a parallel between the Court's reasoning about competition policy, on the one hand, and the rejected views of Justices Hugo Black and William O. Douglas and abandoned patent-antitrust jurisprudence, on the other. The Federal Circuit's decision in Festo Corp. v. Shoketsu Kinzoku Kogyo Kabushiki Co., Ltd., 234 F.3d 558 (Fed. Cir. 2000), on the subject of equivalents is considered in the paper. In that decision, the majority adopted a new rule that completely barred infringement under the doctrine of equivalents of any claim limitation where, in prosecution, there had been a narrowing amendment relating to patentability. In the past, prosecution estoppel foreclosing equivalents had been subject to a "flexible bar," which, in some circumstances, allowed for equivalence notwithstanding such an amendment. The article points out that because almost all patents are amended during prosecution, the effect would be to allow widespread copying of patented inventions by trivial modifications of any narrowed claim limitation.

  8. Dynamical responses to external stimuli for both cases of excitatory and inhibitory synchronization in a complex neuronal network.

    Science.gov (United States)

    Kim, Sang-Yoon; Lim, Woochang

    2017-10-01

    For studying how dynamical responses to external stimuli depend on the synaptic-coupling type, we consider two types of excitatory and inhibitory synchronization (i.e., synchronization via synaptic excitation and inhibition) in complex small-world networks of excitatory regular spiking (RS) pyramidal neurons and inhibitory fast spiking (FS) interneurons. For both cases of excitatory and inhibitory synchronization, effects of synaptic couplings on dynamical responses to external time-periodic stimuli S ( t ) (applied to a fraction of neurons) are investigated by varying the driving amplitude A of S ( t ). Stimulated neurons are phase-locked to external stimuli for both cases of excitatory and inhibitory couplings. On the other hand, the stimulation effect on non-stimulated neurons depends on the type of synaptic coupling. The external stimulus S ( t ) makes a constructive effect on excitatory non-stimulated RS neurons (i.e., it causes external phase lockings in the non-stimulated sub-population), while S ( t ) makes a destructive effect on inhibitory non-stimulated FS interneurons (i.e., it breaks up original inhibitory synchronization in the non-stimulated sub-population). As results of these different effects of S ( t ), the type and degree of dynamical response (e.g., synchronization enhancement or suppression), characterized by the dynamical response factor [Formula: see text] (given by the ratio of synchronization degree in the presence and absence of stimulus), are found to vary in a distinctly different way, depending on the synaptic-coupling type. Furthermore, we also measure the matching degree between the dynamics of the two sub-populations of stimulated and non-stimulated neurons in terms of a "cross-correlation" measure [Formula: see text]. With increasing A , based on [Formula: see text], we discuss the cross-correlations between the two sub-populations, affecting the dynamical responses to S ( t ).

  11. Synchronous Gastric Gastrointestinal Stromal Tumor and Colon Adenocarcinoma: A Case Report

    Directory of Open Access Journals (Sweden)

    Thivi Vasilakaki

    2014-01-01

    Full Text Available Gastrointestinal stromal tumors (GISTs represent the majority of primary mesenchymal tumors of the gastrointestinal tract. They are generally considered to be solitary tumors and therefore the synchronous occurrence with other primary malignancies of gastrointestinal track is considered a rare event. Here we present the case of a 75-year-old man admitted to our hospital with a 10-day history of gastrointestinal bleeding. Colonoscopy revealed an ulcerative mass of 4 cm in diameter in the ascending colon. Gastroscopy revealed a bulge in the gastric body measuring 1 cm in diameter with normal overlying mucosa. Surgical intervention was suggested and ileohemicolectomy with regional lymph node resection along with gastric wedge resection was performed. Pathologic examination of the ascending colon mass showed an invasive moderately differentiated adenocarcinoma stage III B (T3N1M0. Grossly resected wedge of stomach showed a well circumscribed intramural tumor which microscopically was consistent with essentially benign gastrointestinal stromal tumor (according to Miettinen criteria. The patient did not receive additional treatment. Two years later the patient showed no evidence of recurrence or metastasis.

  12. Improving policy making through government-industry policy learning: The case of a novel Swedish policy framework

    Stigson, Peter; Dotzauer, Erik; Yan Jinyue

    2009-01-01

    Climate change poses an unprecedented challenge for policy makers. This paper analyzes how industry sector policy expertise can contribute to improved policy making processes. Previous research has identified that policy making benefit by including non-governmental policy analysts in learning processes. Recent climate and energy policy developments, including amendments and the introduction of new initiatives, have rendered current policy regimes as novel to both governments and the industry. This increases business investment risk perceptions and may thus reduce the effectiveness and efficiency of the policy framework. In order to explore how government-industry policy learning can improve policy making in this context, this article studied the Swedish case. A literature survey analyzed how policy learning had been previously addressed, identifying that the current situation regarding novel policies had been overlooked. Interviews provided how industrial actors view Swedish policy implementation processes and participatory aspects thereof. The authors conclude that an increased involvement of the industry sector in policy design and management processes can be an important measure to improve the effectiveness and efficiency of climate and energy policies

    de Saxe Zerden, Lisa; O'Quinn, Erin; Davis, Corey

    2015-01-01

    Evidence-based practice (EBP) combines proven interventions with clinical experience, ethics, and client preferences to inform treatment and services. Although EBP is integrated into most aspects of social work and public health, at times EBP is at odds with social policy. In this article the authors explore the paradox of evidence-based policy using syringe access programs (SAP) as a case example, and review methods of bridging the gap between the emphasis on EBP and lack of evidence informing SAP policy. Analysis includes the overuse of morality policy and examines historical and current theories why this paradox exists. Action steps are highlighted for creating effective policy and opportunities for public health change. Strategies on reframing the problem and shifting target population focus to garner support for evidence-based policy change are included. This interdisciplinary understanding of the way in which these factors converge is a critical first step in moving beyond morality-based policy toward evidence-based policy.

    2014-03-01

    Full Text Available Synchronous cancers account for 0.7-1.8% of all gynecologic cancers. Among them, synchronous ovarian and endometrial cancers are predominant (40-53%. Patients with synchronous cancers have better prognosis than those with single disseminated cancer. We present 10 patients with synchronous ovarian and endometrial cancers who were treated at the Chemotherapy Department of the Medical University of Lodz in 2009-2013. The most often reported symptom of the disease was abnormal vaginal bleeding (6 patients. The range of the patients’ age was 48-62 and the median age was 56. Five patients had stage I of ovarian cancer, single patients had stage IIA, IIB and IIIB, 2 patients had stage IIIC. Three patients had I, 5 – II, and 2 – III stage of endometrial cancer. All patients had endometrioid type of endometrial cancer, 7 of them had also the same histological type of ovarian cancer. All patients had adjuvant chemotherapy because of ovarian cancer, none of them had adjuvant radiotherapy. One patient was lost to follow up. For other patients a median follow up was 13 months (range: 3-53 months. One patient experienced relapse, all patients are alive. Synchronous ovarian and endometrial cancers are usually diagnosed at an earlier stage, have lower histological grade and better prognosis than single cancers. The most common histological type of both endometrial and ovarian cancers is endometrioid carcinoma. The first symptoms reported by our patients and the course of the disease were concordant with data from the literature.

  19. Can a policy program influence policy change? The case of the Swiss EnergieSchweiz program

    International Nuclear Information System (INIS)

    Sager, Fritz; Bürki, Marietta; Luginbühl, Jennifer

    2014-01-01

    This paper investigates the interrelation of policy implementation and policy change by addressing the question of whether and how the Swiss energy program “EnergieSchweiz” influenced policy decisions. We discuss different ways in which a policy program may influence policy change: by negative and positive learning, by coalition building and by policy community building. Respective assumptions are tested in two case studies from the “EnergieSchweiz” program, which was in place from 2000 to 2010. We find that, while the policy program was not critical for the policy change itself, it nevertheless played a role as an agenda setter, as an initiator of learning processes as well as through its policy community. - Highlights: • We investigate how energy policy implementation impacts policy change. • We analyse the Swiss energy program “EnergieSchweiz” in place from 2000 to 2010. • Policy programs alone do not deliver policy change. • But they can influence it by agenda setting and by negative learning. • Expert networks have an influence if there are shared goals

    2016-11-01

    Policy researchers have used various categories of variables to explain why policies change, including those related to institutions, interests and ideas. Recent research has paid growing attention to the role of policy networks-the actors involved in policy-making, their relationships with each other, and the structure formed by those relationships-in policy reform across settings and issues; however, this literature has largely ignored the theoretical integration of networks with other policy theories, including the '3Is' of institutions, interests and ideas. This article proposes a conceptual framework integrating these variables and tests it on three cases of policy change in Burkina Faso, addressing the need for theoretical integration with networks as well as the broader aim of theory-driven health policy analysis research in low- and middle-income countries. We use historical process tracing, a type of comparative case study, to interpret and compare documents and in-depth interview data within and between cases. We found that while network changes were indeed associated with policy reform, this relationship was mediated by one or more of institutions, interests and ideas. In a context of high donor dependency, new donor rules affected the composition and structure of actors in the networks, which enabled the entry and dissemination of new ideas and shifts in the overall balance of interest power ultimately leading to policy change. The case of strategic networking occurred in only one case, by civil society actors, suggesting that network change is rarely the spark that initiates the process towards policy change. This analysis highlights the important role of changes in institutions and ideas to drive policymaking, but hints that network change is a necessary intermediate step in these processes. © The Author 2016.

    Student-teacher and student-student interactions in purely asynchronous distance learning courses are much lacking compared to similar interactions found in face-to-face teaching, causing learners to experience feelings of isolation, thus reducing motivation and increasing dropout rates. We used PalTalk, an Internet text and audio chat client from AVM Software, Inc. (New York, NY), to offer our students live virtual classroom sessions within a unit of our online distance learning M.Sc. program in Healthcare Informatics. On-demand replays of audio excerpts from the sessions were also provided to accommodate absenteeism and for student review. Five students completed an evaluation questionnaire. Our results highlighted the potential merits of using synchronous conferencing to assist in fostering a sense of belonging to one supportive learning community among distance learners and improve educational outcomes. Students were very positive toward the real-time human interaction and voted for a 95/5 (asynchronous/synchronous percentages) blended delivery approach for a typical unit in our program. They also praised PalTalk's voice quality and ease of use. This paper presents educational and technological perspectives about this experiment in the form of a state-of the- art review, without intending to be statistically rigorous. However, robust research evidence is still required to convince educators fully about the benefits of synchronous communication tools and help them decide on the most suitable solutions for their particular circumstances.

    Significant research attention has been given to understanding the processes of drug policy reform. However, there has been surprisingly little analysis of the persistence of policy in the face of opposition and evidence of ineffectiveness. In this article we analysed just such a case - police drug detection dog policy in NSW, Australia. We sought to identify factors which may account for the continuation of this policy, in spite of counter-evidence and concerted advocacy. The analysis was conducted using the Advocacy Coalition Framework (ACF). We collated documents relating to NSW drug detection dog policy from 1995 to 2016, including parliamentary records (NSW Parliament Hansard), government and institutional reports, legislation, police procedures, books, media, and academic publications. Texts were then read, coded and classified against the core dimensions of the ACF, including subsystem actors and coalitions, their belief systems and resources and venues employed for policy debate. Three coalitions were identified as competing in the policy subsystem: security/law and order, civil liberties and harm reduction. Factors that aided policy stability were the continued dominance of the security/law and order coalition since they introduced the drug dog policy; a power imbalance enabling the ruling coalition to limit when and where the policy was discussed; and a highly adversarial policy subsystem. In this context even technical knowledge that dogs infringed civil liberties and increased risks of overdose were readily downplayed, leading to only incremental changes in implementation rather than policy cessation or wholesale revision. The analysis provides new insights into why the accumulation of new evidence and advocacy efforts can be insufficient to drive significant policy change. It poses a challenge for the evidence-based paradigm suggesting that in highly adversarial policy subsystems new evidence is unlikely to generate policy change without broader

    The purpose of this document is to present a case study of energy policies in California related to power system transformation and renewable and distributed energy resources (DERs). Distributed energy resources represent a broad range of technologies that can significantly impact how much, and when, electricity is demanded from the grid. Key policies and proceedings related to power system transformation and DERs are grouped into the following categories: 1.Policies that support achieving environmental and climate goals 2.Policies that promote deployment of DERs 3.Policies that support reliability and integration of DERs 4.Policies that promote market animation and support customer choice. Major challenges going forward are forecasting and modeling DERs, regulatory and utility business model issues, reliability, valuation and pricing, and data management and sharing.

    AIM: To investigate whether the use of synchronous hepatectomy and splenectomy (HS) is more effective than hepatectomy alone (HA) for patients with hepatocellular carcinoma (HCC) and hypersplenism. METHODS: From January 2007 to March 2013, 84 consecutive patients with HCC and hypersplenism who underwent synchronous hepatectomy and splenectomy in our center were compared with 84 well-matched patients from a pool of 268 patients who underwent hepatectomy alone. The short-term and long-term outcomes of the two groups were analyzed and compared. RESULTS: The mean time to recurrence was 21.11 ± 12.04 mo in the HS group and 11.23 ± 8.73 mo in the HA group, and these values were significantly different (P = 0.001). The 1-, 3-, 5-, and 7-year disease-free survival rates for the patients in the HS group and the HA group were 86.7%, 70.9%, 52.7%, and 45.9% and 88.1%, 59.4%, 43.3%, and 39.5%, respectively (P = 0.008). Platelet and white blood cell counts in the HS group were significantly increased compared with the HA group one day, one week, one month and one year postoperatively (P Splenectomy and micro-vascular invasion were significant independent prognostic factors for disease-free survival. Gender, tumor number, and recurrence were independent prognostic factors for overall survival. CONCLUSION: Synchronous hepatectomy and hepatectomy potentially improves disease-free survival rates and alleviates hypersplenism without increasing the surgical risks for patients with HCC and hypersplenism.

The authors' aim is to analyze the aspects and the implications of the EU governance at the Member States' domestic policies level, as most of these policies are currently facing the challenges brought by the Europeanization process. Therefore, the theoretical framework selected is the theory of governance, focusing on the explanatory and analytical opportunities of two components – multi-level governance and governance networks; in this way, it is underlined the separation from the classic model of relation between the (multiplied levels of political authority (supranational, national, subnational and the exponential increase in the number and types of actors participating at the decisional process and implementation of European public policy. Within the selected case studies (environmental policy and education policy, the authors advance a research structure with the aims (a to identify the relevant actors involved in the policy-making process of these policies, at all stages of its cycle; (b to offer an explanation of the types of interactions between these actors, and (c to identify the influence these interactions exert on the communitarization pronounced tendency of some EU policy sectors. The analysis is performed in terms of the Treaty of Lisbon (the selected policies being part of distinct categories of the Union competences and it is oriented towards the national level of the making process of these policies.

    Asynchronous and periodically-synchronous schemes for coupling atmosphere and ocean models are presented. The performance of the schemes is tested by simulating the climatic response to a step function forcing and to a gradually increasing forcing with a simple zero-dimensional non-linear energy balance model. Both the initial transient response and the asymptotic approach of the equilibrium state are studied. If no annual cycle is allowed the asynchronous coupling technique proves to be a suitable tool. However, if the annual cycle is retained, the periodically-synchronous coupling technique reproduces the results of the synchronously coupled runs with smaller bias. In this case it is important that the total length of one synchronous period and one ocean only period is not a multiple of 6 months. (orig.)

    2013-02-01

    Policy work is often cited as one of the primary functions of Hospital Ethics Committees (HECs), along with consultation and education. Hospital policies can have far reaching effects on a wide array of stakeholders including, care providers, patients, families, the culture of the organisation and the community at large. In comparison with the wealth of information available about the emerging practice of ethics consultation, relatively little attention has been paid to the policy work of HECs. In this paper, we hope to advance the development of best practices in HEC policy work by describing the quality improvement process that we undertook at Hamilton Health Sciences, Hamilton, Ontario, Canada. In the first section of the paper we describe the context of our HEC policy work, and the shortcomings of our historical review process. In subsequent sections, we detail the quality improvement project we undertook in 2010, the results of the project and the specific tools we developed to enhance the quality of HEC policy work. Our goal in sharing this organisational case study is to prompt other HECs to publish qualitative descriptions of their policy work, in order to generate a body of knowledge that can inform the development of best practices for ethics policy review.

    In the context of the global obesity epidemic, national nutrition policies have come under scrutiny. The present paper examines whose interests - industry or public health - are served by these policies and why. Using an exemplary case study of submissions to an inquiry into obesity, the research compared the positions of industry and public health groups with that taken by government. We assessed whether the interests were given equal consideration (a pluralist model of influence) or whether the interests of one group were favoured over the other (a neo-pluralist model). 2006 New Zealand Inquiry into Obesity. Food and advertising industry and public health submitters. The Government's position was largely aligned with industry interests in three of four policy domains: the national obesity strategy; food industry policy; and advertising and marketing policies. The exception to this was nutrition policy in schools, where the Government's position was aligned with public health interests. These findings support the neo-pluralist model of interest group influence. The dominance of the food industry in national nutrition policy needs to be addressed. It is in the interests of the public, industry and the state that government regulates the food and advertising industries and limits the involvement of industry in policy making. Failure to do so will be costly for individuals, in terms of poor health and earlier death, costly to governments in terms of the associated health costs, and costly to both the government and industry due to losses in human productivity.

    Insight in the local policy options with respect to climate change is provided, in this case within the sphere of influence of Amsterdam local authorities. A list of new policy options for CO 2 reduction has been made with the assistance of local policy makers and representatives of interest groups. These policy options have been divided into three qualitative scenarios: Institutional Cultural Change, Technological Innovation and Least-Regrets. The environmental, economic and other effects have been described for each policy option. The three most interesting policy options have been selected by local policymakers and representatives of interest groups during a workshop. Implementation strategies have been developed for the options selected. These strategies have been discussed during a second workshop. The reduction target, stabilisation of CO 2 emissions in 2015 compared to 1993, can be reached by a combination of all the new policy options. The three selected policy options count for 40% of this total CO 2 emission reduction. Finally, a general outline on the methodology can also be applied to other cities and municipalities. For example, this methodology can be used by participants of Cities for Climate Protection, an initiative of the International Council for Local Environmental Initiatives, or the Netherlands Climate Association. 136 refs

  2. Neural Synchronization and Cryptography

    Science.gov (United States)

    Ruttor, Andreas

    2007-11-01

    Neural networks can synchronize by learning from each other. In the case of discrete weights full synchronization is achieved in a finite number of steps. Additional networks can be trained by using the inputs and outputs generated during this process as examples. Several learning rules for both tasks are presented and analyzed. In the case of Tree Parity Machines synchronization is much faster than learning. Scaling laws for the number of steps needed for full synchronization and successful learning are derived using analytical models. They indicate that the difference between both processes can be controlled by changing the synaptic depth. In the case of bidirectional interaction the synchronization time increases proportional to the square of this parameter, but it grows exponentially, if information is transmitted in one direction only. Because of this effect neural synchronization can be used to construct a cryptographic key-exchange protocol. Here the partners benefit from mutual interaction, so that a passive attacker is usually unable to learn the generated key in time. The success probabilities of different attack methods are determined by numerical simulations and scaling laws are derived from the data. They show that the partners can reach any desired level of security by just increasing the synaptic depth. Then the complexity of a successful attack grows exponentially, but there is only a polynomial increase of the effort needed to generate a key. Further improvements of security are possible by replacing the random inputs with queries generated by the partners.

  4. Biomass energy policy in Africa: selected case studies

    1997-01-01

    The majority of the population in the continent of Africa depend on biomass as a source of energy. Woodfuel (charcoal and fuelwood), the most important source of energy, is a subject of major concern in developing countries mainly because of its increasing scarcity, and recently because of its importance to the debate on climate change as its use is associated with emission on the greenhouse gases (GHG's). The book discusses the biomass energy problem and the policy options for addressing it in Botswana and Rwanda. Though the studies mainly draw their material from the surveys undertaken in these countries, extensive use is made of the existing general literature on this subject. The two case studies on Botswana address the nature, extent, and policy implications of the fuelwood problem, including the extent to which it contributes to deforestation. The Rwanda case studies examine the seasonal and spatial variation of the consumption of biomass energy (woodfuel and residues) and the evolution of the energy policy process with particular reference to biomass energy. A number of policy recommendations are made which may not only be relevant to Botswana and Rwanda, but also to other developing countries in a similar situation. The book thus makes a valuable contribution to the scarce literature on energy and environment in Africa. The multi-disciplinarity of the book makes it more valuable to a large number of readers. It will be an important reference material for policy makers and researchers in Africa as well as other developing countries. AFREPREN The African Energy Policy Research Network (AFREPREN) promotes research on energy issues relevant to the formulation and implementation of policy by African governments. It also aims to build research capability as well as mobilize existing expertise to address both near- and long-term challenges faced by the energy sector in Africa. (UK)

    2012-01-01

    Children with cerebral palsy (CP) require individualized long-term management to maintain and improve motor functions. The objective of this study was to explore potential effects of synchronized metronome training (SMT) on movement kinematics in two children diagnosed with spastic hemiplegic CP (HCP). Both children underwent 4-weeks/12 sessions of SMT by means of the Interactive Metronome (IM). Optoelectronic registrations of goal-directed uni- and bimanual upper-limb movements were made at three occasions; pre-training, post completed training and at 6-months post completed training. Significant changes in kinematic outcomes following IM training were found for both cases. Findings included smoother and shorter movement trajectories in the bimanual condition, especially for the affected side. In the unimanual condition, Case I also showed increased smoothness of the non-affected side. The observed short- and long-term effects on the spatio-temporal organization of upper-limb movements need to be corroborated and extended by further case-control studies.

    Full Text Available This paper examines the complexity of the Iranian foreign policy through the case of Iranian nuclear program. The paper aims to assess foreign policy orientations and compares actions of the last three Iranian presidents, Mohammad Khatami, Mahmoud Ahmadinejad and current Hassan Rouhani in dealing with the international community (IC in pursuing its nuclear program. This assessment would not be complete without reference to the Iranian supreme leader Ali Khamenei who is actual head of the state and the most powerful political authority. This paper also relates Iranian foreign policy expectation to competing theories of international relations to identify the most dominant or the most consistent policy orientation. Its aim is to strengthen realist and power-based explanations that have dominated the discourse on Middle Eastern in general and Iranian foreign policy in particular. In this context, a number of questions will be addressed here. To what extend was Iranian negotiation with the IC over its nuclear program consistent throughout these three presidencies? What has changed, if anything, from Iranian foreign policy perspective and why? Can Iranian foreign policy behavior on this specific topic and in this specific time be explained through any international relations theory? As there are many other questions, so there are many theories to examine and explain true Iranian intentions, those below the surface of declared goals (Hadzikadunic, 2014. The methods employed in answering these questions are largely structured around a chronological account and comparative approach. It is also based on the analysis of foreign policy discourse and the assessment of key decision makers.

    2016-07-01

    There is a long standing debate about perverse effects of performance indicators. A main target is science policy using stimulation of output as instrument. The criticism is to a large extent based on a study of the Australian science policy in the early 1990s. Linda Butler studied the effects and argued that the effect was an growth of output, but also a decrease of average quality of the output. These results have been cited many times. In this paper we reanalyze this case and show that the analysis of Butler was wrong: the new Australian science policy did not only increase the output of the system, but also the quality went up. We discuss the implications. (Author)

    Abstract Introduction Acute acalculous cholecystitis is traditionally associated with elderly or critically ill patients. Case presentation We present the case of an otherwise healthy 23-year-old Caucasian man who presented with acute right-sided abdominal pain. An ultrasound examination revealed evidence of acute acalculous cholecystitis. A laparoscopy was undertaken and the dual pathologies of acute acalculous cholecystitis and acute appendicitis were discovered and a laparoscopic cholecystectomy and appendectomy were performed. Conclusion Acute acalculous cholecystitis is a rare clinical entity in young, healthy patients and this report describes the unusual association of acute acalculous cholecystitis and appendicitis. A single stage combined laparoscopic appendectomy and cholecystectomy is an effective treatment modality.

    Multifocal central giant cell granulomas (CGCG) in the maxillofacial region are suggestive of systemic disease such as hyperparathyroidism or an inherited syndrome such as Noonan-like multiple giant cell lesion syndrome. Only 5 cases of multifocal CGCGs in the maxillofacial region without any concomitant systemic disease have currently been reported. We report here on an unusual case of 17-year-old man who presented with multifocal CGCGs of the bilateral posterior mandible and right maxilla and he was without any concomitant systemic disease

    The control of childhood tuberculosis (TB) has been of low priority in TB programmes in high-burden settings. The objective of this paper was to describe the development and testing of tools for the management of childhood TB. The Pakistan National TB Control Programme embarked on a number of activities, including the establishment of policy guidelines for the management of childhood TB and later a guidance document, 'Case Management Desk Guide and Structured Monitoring', to demonstrate the implementation of childhood TB interventions in a programme context. Initial results showed improved case finding and treatment outcome in implementation sites compared with control districts. However, further programme attention is required to improve quality.

  15. Improving biomedical journals' ethical policies: the case of research misconduct.

    Science.gov (United States)

    Bosch, Xavier

    2014-09-01

    Scientific journals may incur scientific error if articles are tainted by research misconduct. While some journals' ethical policies, especially those on conflicts of interest, have improved over recent years, with some adopting a uniform approach, only around half of biomedical journals, principally those with higher impact factors, currently have formal misconduct policies, mainly for handling allegations. Worryingly, since a response to allegations would reasonably require an a priori definition, far fewer journals have publicly available definitions of misconduct. While some journals and editors' associations have taken significant steps to prevent and detect misconduct and respond to allegations, the content, visibility of and access to these policies varies considerably. In addition, while the lack of misconduct policies may prompt and maintain a de novo approach for journals, potentially causing stress, publication delays and even legal disputes, the lack of uniformity may be a matter of contention for research stakeholders such as editors, authors and their institutions, and publishers. Although each case may need an individual approach, I argue that posting highly visible, readily accessible, comprehensive, consistent misconduct policies could prevent the publication of fraudulent papers, increase the number of retractions of already published papers and, perhaps, reduce research misconduct. Although legally problematic, a concerted approach, with sharing of information between editors, which is clearly explained in journal websites, could also help. Ideally, journals, editors' associations, and publishers should seek consistency and homogenise misconduct policies to maintain public confidence in the integrity of biomedical research publications.

    Rossow, Ingeborg; Bang Hansen, Marianne

    2016-04-01

    The aim of this paper is to provide an overview of the development and current status of gambling and gambling policy in Norway. An overview of the research literature and official documents and websites. Gambling on electronic gaming machines (EGMs) increased dramatically in the 1990s in response to technological development and liberalization of gambling policy. Restrictions on availability of EGM gambling occurred from 2006 to 2009 and included a ban on note acceptors, a temporary ban on EGMs and re-introduction of fewer and less aggressive machines under a state monopoly. The restrictions led to significant decreases in total gambling turnover, and several studies suggest that they led to fewer gambling and gambling problems. Various factors may explain why the restrictions were politically feasible. These include media coverage of gambling concerns and economic compensation for revenue losses under the monopoly. In an international context of deregulation of gambling markets, the Norwegian policy restrictions on gambling availability have represented an exceptional case and provide a rare opportunity to explore the outcomes of such regulations. Overall, studies suggest that the policy restrictions have led to reductions in gambling expenditures and problem gambling. © 2015 Society for the Study of Addiction.

  20. Linking biomedical engineering ethics case study approach and policy.

    Dibrell, William; Dobie, Elizabeth Ann

    2007-01-01

    In this paper we link bioengineering case study methods to the development of policy. The case study approach to ethics is an excellent way to show the complex nature of practical/moral reasoning. This approach can, however, lead to a kind of overwhelming complexity. The individual nature of each case makes it difficult to identify the most important information and difficult to see what moral considerations are most relevant. In order to make the overwhelming complexity less debilitating, we present a framework for moral decision making derived from suggestions made by W.D. Ross and Virginia Held. Ross articulates the multiple sources of morality and Held deepens the discussion by reminding us of the foundational importance of care and sympathy to our moral natures. We show how to use the notion of prima facie duty and discuss moral conflict. In doing this, we show how the framework, applied to cases, can be of assistance in helping us develop policies and codes of ethics with sufficient plasticity to be useful in the complex world of the bioengineer.

    2005-01-01

    Increased reliance on optimistic data replication has led to burgeoning interest in tools and frameworks for disconnected updates to replicated data.We have implemented a generic synchronization framework, called HARMONY, that can be used to build state-based synchronizers for a wide variety...... of tree-structureddata formats. A novel feature of this framework is that the synchronization process - in particular, the recognition of conflicts - is driven by the schema of the structures being synchronized.We formalize HARMONY's synchronization algorithm, state a simple and intuitive specification......, and illustrate, using simple address books as a case study, how it can be used to synchronize trees representing a variety of specific forms of applicationdata, including sets, records, tuples, and relations....

    Synchronizing neural processes, mental activities, and social interactions is considered to be fundamental for the creation of temporal order on the personal and interpersonal level. Several different types of synchronization are distinguished, and for each of them examples are given: self-organized synchronizations on the neural level giving rise to pre-semantically defined time windows of some tens of milliseconds and of approximately 3 s; time windows that are created by synchronizing different neural representations, as for instance in aesthetic appreciations or moral judgments; and synchronization of biological rhythms with geophysical cycles, like the circadian clock with the 24-hr rhythm of day and night. For the latter type of synchronization, an experiment is described that shows the importance of social interactions for sharing or avoiding common time. In a group study with four subjects being completely isolated together for 3 weeks from the external world, social interactions resulted both in intra- and interindividual circadian synchronization and desynchronization. A unique phenomenon in circadian regulation is described, the "beat phenomenon," which has been made visible by the interaction of two circadian rhythms with different frequencies in one body. The separation of the two physiological rhythms was the consequence of social interactions, that is, by the desire of a subject to share and to escape common time during different phases of the long-term experiment. The theoretical arguments on synchronization are summarized with the general statement: "Nothing in cognitive science makes sense except in the light of time windows." The hypothesis is forwarded that time windows that express discrete timing mechanisms in behavioral control and on the level of conscious experiences are the necessary bases to create cognitive order, and it is suggested that time windows are implemented by neural oscillations in different frequency domains. © 2015 The

    Classical synchronous motors are the most effective device to drive industrial production systems and robots with precision and rapidity. However, numerous applications require efficient controls in non-conventional situations. Firstly, this is the case with synchronous motors supplied by thyristor line-commutated inverters, or with synchronous motors with faults on one or several phases. Secondly, many drive systems use non-conventional motors such as polyphase (more than three phases) synchronous motors, synchronous motors with double excitation, permanent magnet linear synchronous motors,

  5. The role of organizational culture in policy mobilities – the case of South Korean climate change adaptation policies

    Directory of Open Access Journals (Sweden)

    S. Schäfer

    2017-07-01

    Full Text Available The conceptualization of policies as mobile and mutable knowledge is the key feature of the recent debate on policy mobilities. Policy mobility studies have focused on the movement and translation of policies as well as on the impact of mobile policies on policy-making processes and governed spaces. Given that policy mobilities have mainly been examined in comparable institutional contexts, the current debate has neglected the role of organizational culture in the translation of policies. Organizational culture is understood as a set of shared assumptions that guide what happens in organizations by defining appropriate practices of policy making. The case study, South Korean adaptation policy, illustrates that organizational culture has a significant impact on the translation of mobile adaptation policy. Besides the claim to consider organizational culture more prominently in the field of policy mobility studies, this paper illustrates the translation process of adaptation policy in the South Korean political system. The practices in South Korean political institutions dealing with climate change adaptation are highly characterized by the avoidance of risks. The propensity to avoid risks leads policy makers to focus on technical solutions to climate change adaptation and to neglect the participation of civil society.

    This document presents a case study of energy policies in Texas related to power system transformation, renewable energy and distributed energy resources (DERs). Texas has experienced a dramatic increase in installed wind capacity, from 116 MW in 2000 to over 15,000 MW in 2015. This achievement was enabled by the designation of Competitive Renewable Energy Zones (CREZs) and new transmission lines that transmit wind to load centers. This report highlights nascent efforts to include DERs in the ERCOT market. As costs decline and adoption rates increase, ERCOT expects distributed generation to have an increasing effect on grid operations, while bringing potentially valuable new resources to the wholesale markets.

With a commitment to achieving the Millennium Development Goal (MDG 5 target of maternal mortality rate (MMR of 70/100 000 by 2015, the Ministry of Health (MoH issued the National Plan for Safe Motherhood (NPSM 2003-2010. In 2008, reproductive health, including safe motherhood (SM became a national health target program with annual government funding. Methods A case study of how SM emerged as a political priority in Vietnam over the period 2001-2008, drawing on Kingdon’s theory of agenda-setting was conducted. A mixed method was adopted for this study of the NPSM. Results Three related streams contributed to SM priority in Vietnam: (1 the problem of high MMR was officially recognized from high-quality research, (2 the strong roles of policy champion from MoH in advocating for the needs to reducing MMR as well as support from government and donors, and (3 the national and international events, providing favorable context for this issue to emerge on policy agenda. Conclusion This paper draws on the theory of agenda-setting to analyze the Vietnam experience and to develop guidance for SM a political priority in other high maternal mortality communities.

In Brazil, the most prominent network in recent years is Facebook, which reached 76 million users in June 2013, an unprecedented number in the country. The growth allowed governments to perceive this virtual space as a potential place to present their work and communicate with society. Objectives: The study goal is to observe how information has been publicized by the Ministry of Health through Facebook since 2010 (year of creation of the page until October 2013, taking as an analytical category the implemented information policy, in order to propose a discussion about democratization of access to health information. Methodology: case study; Non-participant observation, data collection and documental analysis. Results: The main issues addressed by the Ministry of Health on Facebook are organizational actions and government programs instead of posts with guidance for a healthy living style. Also noteworthy is the low interaction of the Ministry page moderators with the users profile. The study showed most of the questions and comments made by the public are not answered by the institutional body. Conclusions: Need of strengthening the mediaton process of the information policies from the Ministry of Health on Facebook.

    de Moura, Vicente

    2014-06-01

    This article presents the history of one until now unknown case of C.G. Jung: Maggy Reichstein. Born in Indonesia in 1894 in a very aristocratic family, she brought her sister to Zurich to be treated by Jung in 1919, and later she herself was in analysis with him. Jung used her case as example in his lecture in 1937 on the realities of practical psychotherapy, relating it to the process of transference and countertransference. Jung deepened his studies in Eastern psychology after a series of dreams she had, which culminated in the Yoga Kundalini Seminars. She was also the case presented in his article of 1951 on the concept of synchronicity. Jung wrote that her case, concerning synchronicity, remained unique in his experience. Jung also published some of her mandalas. He considered her able to understand his ideas in depth. Reichstein was for Jung an important case, which challenged and triggered his interests in different subjects. © 2014, The Society of Analytical Psychology.

    2011-01-01

    Full Text Available Abstract Introduction Examples of the spontaneous regression of primary intracranial germinomas can be found in the literature. We present the case of a patient with disseminated lesions of primary intracranial germinoma which synchronously shrunk following diagnostic irradiation. We will discuss whether this regression was spontaneous or radiation-induced. Case presentation A 43-year-old Japanese woman presented to our hospital complaining of memory problems over a period of one year and blurred vision over a period of three months. Following magnetic resonance imaging, she was found to have a massive lesion in the third ventricle and small lesions in the pineal region, fourth ventricle, and in the anterior horn of the left lateral ventricle. Prior to an open biopsy to confirm the pathology of the lesions, she underwent a single cranial computed tomography scan and a single cranial digital subtraction angiography for a transcranial biopsy. Fourteen days after the first magnetic resonance image - 12 and eight days after the computed tomography scan and digital subtraction angiography, respectively - a pre-operative magnetic resonance image was taken, which showed a notable synchronous shrinkage of the third ventricle tumor, as well as shrinkage of the lesions in the pineal region and in the fourth ventricle. She did not undergo steroid administration until after a biopsy that confirmed the pathological diagnosis of pure germinoma. She then underwent whole craniospinal irradiation and went into a complete remission. Conclusions In our case report, we state that diagnostic radiation can induce the regression of germinomas; this is the most reasonable explanation for the synchronous multiple regression observed in this case of germinoma. Clinicians should keep this non-spontaneous regression in mind and monitor germinoma lesions with minimal exposure to diagnostic radiation before diagnostic confirmation, and also before radiation treatment with or

    Context. To report a patient with hyperthyroidism who developed concurrent occurrence of agranulocytosis and severe hepatotoxicity after taking methimazole (MMI). Case. A 51-year-old Chinese male was diagnosed as hyperthyroidism with normal white blood count and liver function. After 4 weeks' treatment with MMI 20 mg/d, it developed to agranulocytosis and severe cholestatic hepatotoxicity. The patient's symptoms and laboratory abnormalities disappeared after the withdrawal of MMI; his white blood count and liver function recover to normal in 2 weeks and 5 weeks, respectively. 296 MBq dose of 131I was given to the patient 3 weeks after the withdrawal of MMI and his thyroid function was back to normal in 6 months. As we know through literature review, only 5 previous cases reported the synchronous ATD-induced agranulocytosis and severe hepatotoxicity in patients with hyperthyroidism. Methods. Review of the patient's clinical course. Literature review of cases of hyperthyroidism with agranulocytosis and severe hepatotoxicity demonstrated that these complications occurred after taking antithyroid drug (ATD). Conclusions. Patient with hyperthyroidism can have synchronous ATD-induced agranulocytosis and severe hepatotoxicity. This case is extremely rare, but the adverse effects with ATDs is clinically significant. The clinicians need to be careful about this and monitor biochemical of patients who take ATDs. PMID:26060496

  19. Generalized synchronization between chimera states

    Andrzejak, Ralph G.; Ruzzene, Giulia; Malvestio, Irene

    2017-05-01

    Networks of coupled oscillators in chimera states are characterized by an intriguing interplay of synchronous and asynchronous motion. While chimera states were initially discovered in mathematical model systems, there is growing experimental and conceptual evidence that they manifest themselves also in natural and man-made networks. In real-world systems, however, synchronization and desynchronization are not only important within individual networks but also across different interacting networks. It is therefore essential to investigate if chimera states can be synchronized across networks. To address this open problem, we use the classical setting of ring networks of non-locally coupled identical phase oscillators. We apply diffusive drive-response couplings between pairs of such networks that individually show chimera states when there is no coupling between them. The drive and response networks are either identical or they differ by a variable mismatch in their phase lag parameters. In both cases, already for weak couplings, the coherent domain of the response network aligns its position to the one of the driver networks. For identical networks, a sufficiently strong coupling leads to identical synchronization between the drive and response. For non-identical networks, we use the auxiliary system approach to demonstrate that generalized synchronization is established instead. In this case, the response network continues to show a chimera dynamics which however remains distinct from the one of the driver. Hence, segregated synchronized and desynchronized domains in individual networks congregate in generalized synchronization across networks.

    We agree with the Comment by Duckrow and Albano [Phys. Rev. E 67, 063901 (2003)] that mutual information, estimated with an optimized algorithm, can be a useful tool for studying synchronization in real data. However, we point out that the improvement they found is mainly due to an interesting but nonstandard embedding technique used, and not so much due to the algorithm used for the estimation of mutual information itself. We also address the issue of stationarity of electroencephalographic (EEG) data.

  1. Sub-national population policy: the case of North Sulawesi.

    Jones, G W

    1989-04-01

    Since the 1970s, Indonesia has placed increasing emphasis on the development of stronger planning capacity at the regional level; however, the concept of regional autonomy is still viewed with suspicion given Indonesia's history of regional separatist movements. This fact has implications for the need for national population policy to be formulated and implemented with a view toward the varying conditions faced by different provinces and regions. The author presents a case study of fertility, mortality, migration, urbanization, and the development of human capital in 1 Indonesian province--North Sulawesi--to illustrate that special characteristics and internal diversity can demand individualized responses by policy makers. In terms of these 5 areas, the following observations can be made about conditions in North Sulawesi: 1) mortality rates are already below the national average, although infant mortality remains unacceptably high; 2) fertility rates are also well below the national average and approaching replacement level without any aggressive family planning outreach activities, but there remains a need to identify the ultimate fertility target and the extent to which intervention is required; 3) there is little scope for absorbing transmigrants, but there are some major issues regarding population redistribution within the province; 4) although there are no large cities, the increasing dominance of Manado is a concern; and 5) the quality of education and an employment structure to match the well-educated labor force are more important than an expansion of these services. A central concern is the ability of North Sulawesi to prevent "brain drain" to Jakarta; however, the province's capacity to do so is dependent on decisions made in Jakarta about the allocation of revenue, regulations regarding the processing of copra and cloves, new air routes, and the extent of regional autonomy to be tolerated in decisions affecting provincial growth.

    Results of nuclear magnetic resonance exploration in a patient with chronic thrombosis of main pulmonary arteries are used to outline an elementary semiology in agreement with current documented data. Signs observed relate to the thrombosis and showing of flow due to associated pulmonary artery hypertension. Cardiac synchronization is essential: obtaining 2 echos by the spin-echo technique allows differentiation of circulatory slowing phenomena, which provoke increased strength of 2nd echo, from the thrombus itself. Correlations established with V/Q scintigraphy, angiography and CT scan findings in this case provided preliminary evaluation of use of this imaging technique in this affection [fr

    Full Text Available The first objective of this paper is to present theoretical approaches to the impact of trade growth (induced by monetary integration on business cycle synchronization which is an important factor of a country’s readiness for a currency union accession. The main conclusion from the first part of the analysis is that business cycle convergence and the cost of the lack of an autonomous monetary policy depend on intra-industry trade (IIT intensity rather than on general trade growth. The second objective is to assess - using the IIT index as a measure of business cycle synchronization (and of susceptibility to asymmetric shocks transmitted mostly through trade channels - preparedness of the Polish economy to the euro adoption. Calculations reveal that the IIT intensity in Poland is already relatively high (in particular in relations with the euro area members and continues to rise. This confirms the increasing complementarity of Poland’s economy with the economic structures of the euro area partners which reduces the probability of asymmetric shocks.

    2015-08-01

    Full Text Available Policy accountability is a form of manifestation of public officials responsible to the people. One form of policy accountability that is discussed here is street vendors policy accountability, because they are a group of citizens who have the economic activities in public spaces. The existence of this policy how-ever, the number of street vendors from year to year increase in Makassar City. Therefore, this study seeks to uncover and explain the democratic policy ac-countability through the street vendors’ responses and expectations to the implementation of street ven-dors empowerment policy in Makassar City; and to uncover and explain the democratic policy account-ability through the stakeholders’ responses and ex-pectations to the implementation of street vendors empowerment policy in Makassar City. To achieve these objectives, the study uses democracy theory, in which this theory focuses on togetherness in dis-cussing solutions to the various problems of street vendors and in the policy implementation as well.This study used a qualitative design and case studies strat-egy. Data collection techniques used was observa-tion, interview, and documentation. Data were ana-lyzed with case description its settings. The results of this study pointed out that the interests and needs of the street vendors are not met through the empow-erment policies vendors. This is caused by the ab-sence of accountability forum as a place of togeth-erness all of street vendors empowerment stakehold-ers’. Street vendors empowerment policy in Makassar City are designed base on a top-down approach, so they are considered as objects, which must accept all government programs aimed at them.

  7. Handling uncertainty in bioenergy policy design – A case study analysis of UK and German bioelectricity policy instruments

    International Nuclear Information System (INIS)

    Purkus, Alexandra; Röder, Mirjam; Gawel, Erik; Thrän, Daniela; Thornley, Patricia

    2015-01-01

    In designing policies to promote bioenergy, policy makers face challenges concerning uncertainties about the sustainability of bioenergy pathways (including greenhouse gas balances), technology and resource costs, or future energy market framework conditions. New information becomes available with time, but policy adjustments can involve high levels of adaptation costs. To enable an effective steering of technology choices and innovation, policies have to strike a balance between creating a consistent institutional framework, which establishes planning security for investors, and sufficient flexibility to adapt to new information. This paper examines implications of economic theory for handling cost and benefit uncertainty in bioelectricity policy design, focussing on choices between price and quantity instruments, technology differentiation, and policy adjustment. Findings are applied to two case studies, the UK's Renewables Obligation and the German feed-in tariff/feed-in premium scheme. Case study results show the trade-offs that are involved in instrument choice and design – depending on political priorities and a country's specific context, different options can prove more adequate. Combining market-based remuneration with sustainability criteria results in strong incentives for bioenergy producers to search for low-cost solutions; whereas cost-based price instruments with centrally steered technology and feedstock choices offer higher planning security for investors and more direct control for policy makers over what pathways are implemented. Independent of the choice of instrument type and technology differentiation mechanism, findings emphasise the importance of a careful policy design, which determines the exact balance between performance criteria such as cost control, incentive intensity, planning security and adaptive efficiency. - Highlights: • Bioelectricity policy design must deal with simultaneous cost and benefit uncertainty.

    Full Text Available The paper investigates the synchronization of price changes in the context of retail tire dealers in São Paulo-Brazil and selected items in supermarkets for cleaning supplies and food in Rio de Janeiro-Brazil. Results indicate similar and non-negligible synchronization for different brands, although magnitudes are distant from a perfect synchronization pattern. We find interesting patterns in inter-firm competition, with similar magnitudes across different tire types. Intra-chain synchronization is substantial, indicating that a common price adjustment policy tends to be sustained for each chain across different products.

  10. Integrating science, economics and law into policy: The case of carbon sequestration in climate change policy

    Science.gov (United States)

    Richards, Kenneth

    Carbon sequestration, the extraction and storage of carbon from the atmosphere by biomass, could potentially provide a cost-effective means to reduce net greenhouse gas emissions. The claims on behalf of carbon sequestration may be inadvertently overstated, however. Several key observations emerge from this study. First, although carbon sequestration studies all report results in terms of dollars per ton, the definition of that term varies significantly, meaning that the results of various analyses can not be meaningfully compared. Second, when carbon sequestration is included in an energy-economy model of climate change policy, it appears that carbon sequestration could play a major, if not dominant role in a national carbon emission abatement program, reducing costs of emissions stabilization by as much as 80 percent, saving tens of billions of dollars per year. However, the results are very dependant upon landowners' perceived risk. Studies may also have overstated the potential for carbon sequestration because they have not considered the implementation process. This study demonstrates that three factors will reduce the cost-effectiveness of carbon sequestration. First, the implementation costs associated with measurement and governance of the government-private sector relation are higher than in the case of carbon source control. Second, legal constraints limit the range of instruments that the government can use to induce private landowners to expand their carbon sinks. The government will likely have to pay private parties to expand their sinks, or undertake direct government production. In either case, additional revenues will be required, introducing social costs associated with excess burden. Third, because of the very long time involved in developing carbon sinks (up to several decades) the government may not be able to make credible commitments against exactions of one type or another that would effectively reduce the value of private sector investments

  12. Affective Policy Performance Evaluation Model: A Case of an International Trade Policy Implementation

    Directory of Open Access Journals (Sweden)

    Inwon Kang

    2018-01-01

    Full Text Available Firms often superficially adopt policies because of governmental rules and regulations, so as to avoid penalties or to gain benefits. However, the evaluation and characterization of those kinds of adoptions as policy performance distorts the true level of policy performance: social sustainability. This study proposes an affective policy performance evaluation model. The attitudes of employees toward adopting a policy are characterized into genuine and superficial compliance. Their behaviors are explained through voluntary and opportunistic adoptions. In order to validate the proposed model, a survey was conducted on an international trade policy target group (n = 216 for the Strategic Trade Control System (STCS, in order to understand their attitudes toward adopting the policy. The survey data was analyzed by a structural equation modeling method. The measures of the factors in the proposed model are adopted and modified from existing studies. The most effective resources of policy implementation on the firms’ genuine and superficial compliance and ultimately on the firms’ voluntary policy adoption are revealed through the analysis. Based on the results, this study presents a strategy for allocating and managing policy implementation resources to exclusively encourage firms’ trade policy adoptions.

    Synchronization is a common phenomenon in physical and biological systems. We examine the synchronization of two (and more) metronomes placed on a freely moving base. The small motion of the base couples the pendulums causing synchronization. The synchronization is generally in-phase, with antiphase synchronization occurring only under special conditions. The metronome system provides a mechanical realization of the popular Kuramoto model for synchronization of biological oscillators, and is excellent for classroom demonstrations and an undergraduate physics lab.

    Existing fault-tolerant clock synchronization algorithms are compared and contrasted. These include the following: software synchronization algorithms, such as convergence-averaging, convergence-nonaveraging, and consistency algorithms, as well as probabilistic synchronization; hardware synchronization algorithms; and hybrid synchronization. The worst-case clock skews guaranteed by representative algorithms are compared, along with other important aspects such as time, message, and cost overhead imposed by the algorithms. More recent developments such as hardware-assisted software synchronization and algorithms for synchronizing large, partially connected distributed systems are especially emphasized.

  15. Evaluation of energy efficiency policy instruments effectiveness : case study Croatia

    International Nuclear Information System (INIS)

    Bukarica, V.

    2007-01-01

    This paper proposed a theoretical basis for evaluating energy efficiency policy in the Republic of Croatia and corroborated it with the analysis of energy efficiency market development and transformation. The current status of the market was evaluated and policy instruments were adapted to achieve optimal results. In particular, the energy efficiency market in Croatia was discussed in terms of micro and macro environment factors that influence policy making processes and the choice of policy instruments. The macro environment for energy efficiency market in Croatia is the process of European Union pre-integration with all related national and international legislation, political and economical factors and potential to use financial funds. The micro environment consists of government institutions, local financing institutions and a range of market players on the supply and demand side. Energy efficiency is the most powerful and cost-effective way for achieving goals of sustainable development. Policy instruments developed to improve energy efficiency are oriented towards a cleaner environment, better standard of living, more competitive industry and improved security of energy supply. Energy efficiency is much harder to implement and requires policy interventions. In response to recent trends in the energy sector, such as deregulation and open competition, policy measures aimed at improving energy efficiency should shift from an end-users oriented approach towards a whole market approach. The optimal policy instruments mix should be designed to meet defined targets. However, market dynamics must be taken into consideration. 9 refs., 4 figs

  16. Problems, policies and politics: making the case for better assistive technology provision in Australia.

    Science.gov (United States)

    Layton, Natasha

    2015-05-01

    Substantial evidence supports assistive technology and environmental adaptations as key enablers to participation. In order to realise the potential of these interventions, they need to be both recognised in policy, and resourced in practice. This paper uses political theory to understand the complexities of assistive technology (AT) policy reform in Australia. AT research will not be influential in improving AT policy without consideration of political drivers. Theories of policy formation are considered, with Kingdon's (2003) theory of multiple streams identified as a useful lens through which to understand government actions. This theory is applied to the case of current AT policy reformulation in Australia. The convergence model of problem identification, policy formulation and political will is found to be an applicable construct with which to evaluate contemporary policy changes. This paper illustrates the cogency of this theory for the field of AT, in the case of Australia's recent disability and aged care reforms. Political theory provides a way of conceptualising the difficulties of consumers and AT practitioners experience in getting therapeutically valid solutions into public policy, and then getting policies prioritised and funded. It is suggested that AT practitioners must comprehend and consider political factors in working towards effective policies to support their practice. AT practitioners generally lack political awareness or an understanding of the drivers of policy. The effectiveness of AT practitioners at a systemic level will remain limited without consideration of policy drivers. AT practitioners must comprehend and consider political factors in working towards effective policies to support their practice.

    Full Text Available This paper seeks to examine the effects of monetary policy over banks' loans growth and whether there is a bank lending channel operating in Brazil. Therefore, we employ a detailed high frequency panel data in which we include bank characteristics and ownership control. We contribute to the literature on bank lending channel by showing that during periods of loosening/tightening monetary policy, banks increase/decrease their loans. Additionally,our results illustrate that large, well-capitalized and liquid banks react differentially to the effects of monetary policy shocks. Finally, we show that the impact of monetary policy differs across state-owned, foreign and private domestic banks. These results are important for developing and conducting monetary policy.

    Nicolli, Francesco; Vona, Francesco

    2014-07-01

    This paper investigates empirically the effect of market regulation and renewable energy policies on innovation activity in different renewable energy technologies. For the EU countries and the years 1980 to 2007, we built a unique dataset containing information on patent production in eight different technologies, proxies of market regulation and technology-specific renewable energy policies. Our main findings show that lowering entry barriers is a more significant driver of renewable energy innovation than privatisation and un-bundling, but its effect varies across technologies, being stronger in technologies characterised by the potential entry of small, independent power producers. Additionally, the inducement effect of renewable energy policies is heterogeneous and more pronounced for wind, which is the only technology that is mature and has high technological potential. Finally, the ratification of the Kyoto protocol - determining a more stable and less uncertain policy framework - amplifies the inducement effect of both energy policy and market liberalisation.

  20. Case studies of green roof policy from Canada

    Energy Technology Data Exchange (ETDEWEB)

    Marshall, S. [Canada Mortgage and Housing Corp., Ottawa, ON (Canada)

    2006-07-01

    In order to overcome environmental, economic, and social challenges, such as stormwater management, heat island effects, reducing energy use in buildings and increasing amenity space, green roof technology has been a key approach used in many European countries and is gaining acceptance throughout North America as knowledge of the environmental benefits and green roof technology grows. While the conditions, benefits and market forces that have driven green roof development in Europe are not identical to Canada's, lessons can be learned from their experiences. Canadian municipalities that are looking to develop and implement green roof policies and programs will need information on how to tailor policies and programs for specific climate conditions, environmental concerns and regulatory realities. In order to provide Canadian municipal decision-makers with an overview of international and local green roof policies and programs, a green roof policy infrastructure manual was recently completed for the Canada Mortgage and Housing Corporation. Decision-makers can be better informed about which policies may be best suited to meet their specific policy needs by reviewing the motivators and other factors behind existing programs around the world. The manual describes green roof policies in each of 12 different jurisdictions from Canada, the United States, Germany, Switzerland, Singapore, and Japan in terms of local green roof motivators and the steps taken along the continuum of establishing policy. This paper described the progress of some Canadian cities that are moving through six phases of establishing appropriate green roof policies and programs. The six phases were introductory and awareness; community engagement; action plan development and implementation; technical research; program and policy development and continuous improvement.

  1. European Union energy policy integration: A case of European Commission policy entrepreneurship and increasing supranationalism

    International Nuclear Information System (INIS)

    Maltby, Tomas

    2013-01-01

    Focusing on gas, this article explores the role of the European Commission in the process of European Union energy security policy development, and the extent to which the policy area is becoming increasingly supranational. Situating the article within the literature on agenda-setting and framing, it is argued that a policy window was opened as a result of: enlargement to include more energy import dependent states, a trend of increasing energy imports and prices, and gas supply disruptions. From the mid-2000s, the Commission contributed to a shift in political norms, successfully framing import dependency as a problem requiring an EU-level solution, based on the institution’s pre-existing preferences for a diversified energy supply and internal energy market. Whilst Member States retain significant sovereignty, the Commission has achieved since 2006 creeping competencies in the internal, and to a lesser extent external, dimensions of EU energy policy. - Highlights: ► We examine the development of EU energy security policy, focusing on gas. ► We examine changes in European Commission competence in energy policy. ► The European Commission has gained increased competence in the internal market. ► In the external dimension of EU energy policy Member States retain competence. ► The European Commission has had qualified success as a policy entrepreneur

    Conserving energy and reducing carbon emissions have become the common responsibility of the international community. During the year 2010, the Taiwan government planned a four-year project budgeted at 300 million US dollars, called “The Penghu Low Carbon Island Development Project.” The policy objective is to use Penghu Island (population 85,000) as a test platform to evaluate new ways to conserve energy and reduce carbon emissions before attempting to replicate the policies on Taiwan Island. For Taiwan, a zero carbon island green transportation policy will regulate the total number of electric scooters, the total number of gasoline motorcycles, influence government subsidy incentives, and create the need for new motorcycle license issuing and control. These factors interact with each other to form a complex and dynamic system that impacts policy as well as the current way of life. In this study, a system dynamics approach is designed to construct a model for evaluating the green transportation policy on Penghu Island. Simulations are conducted to model green transportation system behavior and related policy effects in a smaller, controlled environment before creating policies for Taiwan Island that will impact the lives of over 23 million people. - Highlights: ► Provides an overview of Taiwan's Penghu Low Carbon Island Development Project. ► Develops a systems dynamics approach for green transportation policy assessment. ► Provides causal analysis of social, economic, and environmental factors. ► Demonstrates that the proposed policy cannot meet the CO 2 reduction goals. ► Alternative policies can be evaluated using the proposed approach.

    2011-01-01

    This Letter investigates synchronization issues of complex dynamical networks with switching topology. By constructing a common Lyapunov function, we show that local and global synchronization for a linearly coupled network with switching topology can be evaluated by the time average of second smallest eigenvalues corresponding to the Laplacians of switching topology. This result is quite powerful and can be further used to explore various switching cases for complex dynamical networks. Numerical simulations illustrate the effectiveness of the obtained results in the end. -- Highlights: → Synchronization of complex networks with switching topology is investigated. → A common Lyapunov function is established for synchronization of switching network. → The common Lyapunov function is not necessary to monotonically decrease with time. → Synchronization is determined by the second smallest eigenvalue of its Laplacian. → Synchronization criterion can be used to investigate various switching cases.

    In the domain of environmental policy, the Dutch authorities have changed their course in the mid-1980s towards an integrated approach. As a result, several reports and trends, in which policy recommendations are given for specific target groups and types and pollution, have been adopted. The objective of this paper is, therefore, twofold. First, we sketch the background studies and the context of the discussion that took place in the Netherlands in the last decade. Then, we detail and assess actual policy measures taken or soon to be taken

    2015-12-01

    Many Canadian school jurisdictions have developed nutrition policies to promote health and improve the nutritional status of children, but research is needed to clarify adherence, guide practice-related decisions, and move policy action forward. The purpose of this research was to evaluate policy adherence with a review of online lunch menus of elementary schools in Nova Scotia (NS) while also providing transferable evidence for other jurisdictions. School menus in NS were scanned and a list of commonly offered items were categorized, according to minimum, moderate, or maximum nutrition categories in the NS policy. The results of the menu review showed variability in policy adherence that depended on food preparation practices by schools. Although further research is needed to clarify preparation practices, the previously reported challenges of healthy food preparations (e.g., cost, social norms) suggest that many schools in NS are likely not able to use these healthy preparations, signifying potential noncompliance to the policy. Leadership and partnerships are needed among researchers, policy makers, and nutrition practitioners to address the complexity of issues related to food marketing and social norms that influence school food environments to inspire a culture where healthy and nutritious food is available and accessible to children.

    Anthropogenic activity will bring immediate changes and disruptions to the global climate with accompanying health implications. Although policymakers and public health advocates are beginning to acknowledge the health implications of climate change, current policy approaches are lagging behind. We proposed that 4 key policy principles are critical to successful policymaking in this arena: mainstreaming, linking mitigation and adaptation policy, applying population perspectives, and coordination. We explored California’s progress in addressing the public health challenges of climate change in the San Joaquin Valley as an example. We discussed issues of mental health and climate change, and used the San Joaquin Valley of California as an example to explore policy approaches to health issues and climate change. The California experience is instructive for other jurisdictions. PMID:29072936

We discussed issues of mental health and climate change, and used the San Joaquin Valley of California as an example to explore policy approaches to health issues and climate change. The California experience is instructive for other jurisdictions.

    Malaria due to P. falciparum is the number one cause of morbidity and mortality in Uganda where it is highly endemic in 95% of the country. The use of efficacious and effective antimalarial medicines is one of the key strategies for malaria control. Until 2000, Chloroquine (CQ) was the first-line drug for treatment of uncomplicated malaria in Uganda. Due to progressive resistance to CQ and to a combination of CQ with Sulfadoxine-Pyrimethamine, Uganda in 2004 adopted the use of ACTs as first-line drug for treating uncomplicated malaria. A review of the drug policy change process and postimplementation reports highlight the importance of managing the policy change process, generating evidence for policy decisions and availability of adequate and predictable funding for effective policy roll-out. These and other lessons learnt can be used to guide countries that are considering anti-malarial drug change in future.

    Major uncertainties and conflicting objectives often arise in public policy analysis. This paper advances a framework that is appropriate for public policy problems frequently encountered in agriculture and food systems. Among other possible benefits, its principal value is to provide focus on the major conflicts, trade-offs, and subjective perceptions among affected groups. It can be used to isolate major disagreements, needed empirical evidence, appropriate degrees of risk aversion, equity ...

  15. The case for policy-relevant conservation science.

    Science.gov (United States)

    Rose, David C

    2015-06-01

    Drawing on the "evidence-based" (Sutherland et al. 2013) versus "evidence-informed" debate (Adams & Sandbrook 2013), which has become prominent in conservation science, I argue that science can be influential if it holds a dual reference (Lentsch & Weingart 2011) that contributes to the needs of policy makers whilst maintaining technical rigor. In line with such a strategy, conservation scientists are increasingly recognizing the usefulness of constructing narratives through which to enhance the influence of their evidence (Leslie et al. 2013; Lawton & Rudd 2014). Yet telling stories alone is rarely enough to influence policy; instead, these narratives must be policy relevant. To ensure that evidence is persuasive alongside other factors in a complex policy-making process, conservation scientists could follow 2 steps: reframe within salient political contexts and engage more productively in boundary work, which is defined as the ways in which scientists "construct, negotiate, and defend the boundary between science and policy" (Owens et al. 2006:640). These will both improve the chances of evidence-informed conservation policy. © 2015 The Authors.

The general method of YouTube enhanced case teaching might be expanded beyond health management and policy to other topics in health professions education.

  17. Overview of Cell Synchronization.

    Science.gov (United States)

    Banfalvi, Gaspar

    2017-01-01

    The widespread interest in cell synchronization is maintained by the studies of control mechanism involved in cell cycle regulation. During the synchronization distinct subpopulations of cells are obtained representing different stages of the cell cycle. These subpopulations are then used to study regulatory mechanisms of the cycle at the level of macromolecular biosynthesis (DNA synthesis, gene expression, protein synthesis), protein phosphorylation, development of new drugs, etc. Although several synchronization methods have been described, it is of general interest that scientists get a compilation and an updated view of these synchronization techniques. This introductory chapter summarizes: (1) the basic concepts and principal criteria of cell cycle synchronizations, (2) the most frequently used synchronization methods, such as physical fractionation (flow cytometry, dielectrophoresis, cytofluorometric purification), chemical blockade, (3) synchronization of embryonic cells, (4) synchronization at low temperature, (5) comparison of cell synchrony techniques, (6) synchronization of unicellular organisms, and (7) the effect of synchronization on transfection.

  18. A socio-historical approach to policy analysis: the case of the Brazilian Workers' Food Policy.

    2018-02-05

    Policy analyses based on traditional or structuralist definitions of the state are important, but they have some limitations for explaining processes related to policymaking, implementation, and results. Bourdieusian sociology links the analysis to objective and subjective dimensions of social practices and can help elucidate these phenomena. This article provides such empirical evidence by analyzing the social genesis of a Brazilian policy that currently serves 18 million workers and was established by the state in 1976 through the Fiscal Incentives Program for Workers' Nutrition (PIFAT/PAT). The study linked the analysis of the trajectory of social agents involved in the policy's formulation to the historical conditions that allowed the policy to exist in the first place. Although the literature treats the policy as a workers' food program (PAT), the current study showed that it actually represented a new model for paying financial subsidies to companies that provided food to their employees, meanwhile upgrading the commercial market for collective meals. The study further showed that the program emerged as an administrative policy, but linked to economic agents. The program became a specific social space in which issues related to workers' nutrition became secondary, but useful for disguising what had been an explicit side of its genesis, namely its essentially fiscal nature.

    2010-01-01

    In this article, we explore whether policy network theory can be applied in the People's Republic of China (PRC). We carried out a literature review of how this approach has already been dealt with in the Chinese policy sciences thus far. We then present the key concepts and research approach in policy networks theory in the Western literature and try these on a Chinese case to see the fit. We follow this with a description and analysis of the policy-making process regarding the health insurance reform in China from 1998 until the present. Based on this case study, we argue that this body of theory is useful to describe and explain policy-making processes in the Chinese context. However, limitations in the generic model appear in capturing the fundamentally different political and administrative systems, crucially different cultural values in the applicability of some research methods common in Western countries. Finally, we address which political and cultural aspects turn out to be different in the PRC and how they affect methodological and practical problems that PRC researchers will encounter when studying decision-making processes.

In this paper, we describe the experience of establishing a system of HPSR from the Haryana state in India, outline how the HPSR is being utilized for policy making and programmatic decision making, and analyse the key factors which have been critical to the implementation and uptake of HPSR. Methods: Multiple methods are employed in this case study, ranging from unstructured in-depth interviews, review of the program and policy documents, and participatory notes from the meetings. The steps towards creation of a knowledge partnership between stakeholders are outlined. Four case studies i.e. development of a plan for universal health care (UHC, nutrition policy, centralized drug procurement system and use of RAPID appraisal method highlight the use of research evidence in agenda setting, policy formulation and policy implementation respectively. Results: Our analysis shows that the most important factor which contributed to Haryana model of HPSR was the presence of a dedicated and motivated team in National Rural Health Mission (NRHM at state level, many of whom were researchers by previous training. Overall, we conclude by highlighting the need for establishing an institutional mechanism at Central and State level where health service administrators and managers, academicians and researchers working in the field of health system from medical colleges, public health schools, management and technology institutions and social science universities can identify health system research priorities. Increased budgetary allocation for HPSR is required.

  2. Policy Entrepreneurs and Change Strategies: Lessons from Sixteen Case Studies of Water Transitions around the Globe

    Directory of Open Access Journals (Sweden)

    Sander Meijerink

    2010-06-01

    Full Text Available This paper focuses on the role of policy entrepreneurs in realizing water policy transitions. The central questions are to what extent have policy entrepreneurs played a role in realizing major change in water policies, who are these policy entrepreneurs, and what strategies have they used to bring about change? The policy science literature suggests that policy entrepreneurs have an "arsenal" of possible strategies for achieving change. Based on a comparative analysis of water policy changes in 15 countries around the globe and the European Union, we investigate which strategies have in practice been used by policy entrepreneurs, to what effect, and which lessons for managing water transitions we can draw from this. The comparative case analysis shows that individuals play complementary roles; hence, entrepreneurship in water management is often collective entrepreneurship. Strategies of coalition building, the manipulation of decision making forums, and the strategic framing of issues and windows are crucial to understanding water policy change, which suggests that the management of water policy transitions is a highly political game. We conclude by listing recommendations for those who would like to direct water policy change.

    Smart, C

    1985-11-01

    A detailed examination is presented of the background to the reports and policy developments concerning drug dependence which emerged in Britain during the 1960s. Analysis of documents and interviews with policy makers, officials and doctors involved in the events of the period, reveal that explanatory models in terms of 'moral panic' or 'power struggle' tend to oversimplify the complex processes involved. The role in policy formation of the media, government departments and groups within the medical profession is considered. The patterns of conflict and convergence are seen to overlap simple lines of 'interest'--we find conflict within the medical profession, convergence between the Home Office (legal) and elements of the medical professions (medical). The resulting legal and institutional framework involved only loose guidelines from the centre about treatment, and the shape of policy was determined by individual doctors in the new hospital treatment centres. The apparent re-run of the 1960s being staged in the 1980s will require detailed research in the future in order to avoid superficial comparisons.

    Full Text Available Competitiveness depends to a large extent on innovation. This is true about tourism also. This article focuses on the differences in innovations implemented in the field of tourism policy. The main aim of this article is to evaluate the differences in innovations in tourism policy. The key hypothesis suggests that in the countries undergoing the process of transformation, introduction of innovations is difficult and depends to a large extent on the capability to adopt the new post-industrial tourism paradigm. Poland serves here only as an exemplification of this phenomenon. An additional hypothesis suggests that public policy employs in practice more often “goal substitution” (instead of complex and demanding goals; for instance modernization or renovation instead of urban regeneration or culture or tourism, whereas the business sector is more product-oriented (in line with the new post-industrial paradigm. The article analyses public 2007-2013 strategies (and, to some extent, projects for 2014-2020, but first of all it compares the implementation of the strategy within the operational programs and in private sector activities. Finally, referring to Poland as part of the European Union, the paper proposes that new EU regulations may bring a change in non-product approach to tourism development policy.

    Science.gov (United States)

    Dinour, Lauren M; Kwan, Amy; Freudenberg, Nicholas

    There is growing recognition that policies influence population health, highlighting the need for evidence to inform future policy development and reform. This review describes how comparative case study methodology has been applied to public health policy research and discusses the methodology's potential to contribute to this evidence. English-language, peer-reviewed articles published between 1995 and 2012 were sought from 4 databases. Articles were included if they described comparative case studies addressing US public health policy. Two researchers independently assessed the 20 articles meeting review criteria. Case-related characteristics and research design tactics utilized to minimize threats to reliability and validity, such as the use of multiple sources of evidence and a case study protocol, were extracted from each article. Although comparative case study methodology has been used to analyze a range of public health policies at all stages and levels, articles reported an average use of only 3.65 (out of 10) research design tactics. By expanding the use of accepted research design tactics, public health policy researchers can contribute to expanding the evidence needed to advance health-promoting policies.

    In an experimental investigation of the response of a chaotic system to a chaotic driving force, we have observed synchronization of chaos of the response system in the forms of generalized synchronization, phase synchronization, and lag synchronization to the driving signal. In this paper we compare the features of these forms of synchronized chaos and study their relations and physical origins. We found that different forms of chaotic synchronization could be interpreted as different stages of nonlinear interaction between the coupled chaotic systems.

    While there has been interest in promoting the use of renewable energy in electricity production for a number of years in the United States, the market share of non-hydro renewable energy sources in electricity production has remained at about 2 percent over the past decade. The paper reviews the principal energy resources used for electricity production, considers the changing regulatory environment for the electricity industry, and describes government policies that have been used to promote green electricity in the United States, with an emphasis on measures adopted by state governments. Factors influencing the development of green power markets are also discussed, including underlying economic issues, public policy measures, the regulatory environment, external costs, and subsidies. Without significant increases in fossil fuel prices, much more stringent environmental regulations, or significant changes in electricity customer preferences, green electricity markets are likely to develop slowly in the United States

    2000-01-01

    Full text.The electric energy demand in Lebanon is estimated to grow at an average of 3-5% per year for the coming 10 years. Such an increase in energy demand is problematic for Lebanon since its economy is almost totally dependent on imported fuel which contributes to 97% of the overall energy requirements. Solar water heaters (SWH) are regarded as the most important element in a long term energy conservation and management strategy for this country, but their promotion is a national issue requiring the participation of many stake holders and decision makers. Additionally, the success of solar energy penetration into the existing energy market is constrained by many factors such as technical and financial limitations, decision criteria and policy instruments. This paper will explore the feasibility of SWH, and will work out, using the Analytic Hierarchy Process technique, a policy to ensure a large scale diffusion of SWH in the energy market

    Full Text Available Public insecurity became a central issue for many Hondurans in the late 1990s, as crime, delinquency and homicide increased significantly in the isthmus. Honduras had the second highest homicide rate (35.1 per 100,000 in the region after El Salvador (50.2. per 100,000 . This social violence triggered insecurity and fear, which was further accompanied by the overall perception that the state was unable of relieving or protecting the population. This article looks at the failed attempts of the Honduran state to stop social violence and to control youth gang expansion by focusing on the security policies Cero Tolerancia (Zero Tolerance, Mano Dura (Iron Fist and the Ley Antimaras (Anti-Gang Law. It understands security policies as territorial strategies that attempt to reduce social violence and impose control.

    2015-10-12

    This study investigates the health impacts of a major liberalization episode in the textile and clothing (T&C) sector. This episode triggered substantial shifts in employment across a wide range of countries. It is the first study to empirically link trade liberalization to health via changes in employment and offers some of the first empirical insights on how trade liberalization interacts with social policies to influence health. Data from 32 T&C reliant countries were analysed in reference to the pre- and post-liberalization periods of 2000-2004 and 2005-2009. Fuzzy-set qualitative comparative analysis (fsQCA) was used to examine the association between countries' a) level of development b) labour market and welfare state protections c) T&C employment changes and d) changes in adult female and infant mortality rates. Process tracing was used to further investigate these associations through twelve in-depth country studies. Results from the fsQCA relate changes in employment after the phase-out to both changing adult female and infant mortality rates. Findings from the in-depth country studies suggest that the worsening of adult female mortality rates is related to workers' lack of social protection, both in the context of T&C employment growth and loss. Overall, it is found that social protection is often inaccessible to the type of workers who may be the most vulnerable to processes of liberalization and that many workers are particularly vulnerable due to the structure of social protection policies. Social policies are therefore found to both moderate pathways to health and influence the type of health-related pathways resulting from trade liberalizing policies.

  2. Energy policy and energy market performance: The Argentinean case

    International Nuclear Information System (INIS)

    Recalde, Marina

    2011-01-01

    In the early 1990s Argentina liberalized and privatized the energy system, trending to a total market oriented system and abandoning the use of energy policy. Since 2004, as a result of a boom in energy demand and constrains in energy supply, Argentina has gone through an energy problem mainly related to natural gas and electricity, which derived in energy shutdowns. In this frame, this study explores the role of energy policy and institutions in Argentina, with the aim of discussing whether it has been properly used to contrast the observed lack of coordination between fossil energy reserves management and the demand of fuels in power generation. The results of the analysis enhance the relevance of regulatory and control authorities, as well as the active use of long run energy policy for the energy system performance in order to avoid coordination failures between subsectors of the system. The relevance of energy consumption for the development process, and the particular characteristics of energy systems require a wide planning perspective. - Highlights: → This paper examines some aspects of the performance of the Argentinean energy system and energy policy. → There is a lack of coordination between fossil energy reserves management and electricity demand. → It is required an improvement of the regulatory framework, and an active role of the regulatory authorities. → A better planning for electricity supply and strengthening aspects related to the linking with other energy chains. → Promoting a systematic exploitation of NG and oil reserves' and increasing the share of RETs in the energy mix.

  4. The national energy policy: a case for gas

    2001-01-01

    During the first half of 2001, Australia's Federal, State and Territory governments through COAG have dedicated considerable time to formulating their initial positions on a national energy policy. The formal development of that policy is expected to be agreed at a mid-year meeting of COAG. Given these many benefits, the AGA believes that a national energy policy should: address regulatory constraints on gas market growth and investment; ensure greenhouse programs and measures encourage fuel switching to cleaner energy sources such as natural gas; make gas market contestability regimes consistent and compatible across the States and Territories; improve and streamline project approval processes along the whole gas chain, from exploration and production through to transmission and distribution; remove regulatory structures and market rules that currently inhibit new gas entrants from entering the electricity generation and cogeneration sectors; introduce appropriate taxation regimes for long lived energy infrastructure assets, particularly following the loss of accelerated depreciation; maximise opportunities for energy choice in urban and regional areas and encourage the development, and market uptake, of new gas technologies

Qualitative retrospective case studies drawing from document reviews, semi-structured interviews and in-country validation workshops were conducted in Burkina Faso, Kenya, Malawi, Mali, Mozambique and Niger. These countries were selected to maximise variation in iCCM policy status, community health worker (CHW) models and different African regions. Country iCCM policies evolved in an ad hoc fashion, but were substantially influenced by the history of primary health care and the nature of CHW programmes. Technical officers within Ministries of Health led iCCM policy change with support from international donors, but neither communities nor political leadership was mobilised. Concerns about achieving the Millennium Development Goals, together with recognition of the shortcomings of existing child health programmes, led to the adoption of iCCM policies. Availability of external financing played a critical role in facilitating policy change. iCCM policy change has been promoted by international agencies, but national governments have struggled to align iCCM with country health systems. Greater investment is needed in tailoring global policy initiatives to match country needs. High-level, political ownership of iCCM policies could facilitate policy change, as could clearer strategies for ensuring the long-term sustainability of such policies. © 2014 The Authors.

    Full Text Available The large number of regional trade agreements notified to the World Trade Organization (WTO significantly influenced the flow of world trade. By April 2014 there had been notified 583 regional trade agreements to the WTO, of which only 379 are in force. The objective of this paper is to highlight the importance of regional trade agreements in world trade, especially the importance of establishing a regional competition policy in these agreements. The research methodology used is the analysis of legislation governing preferential trade agreements at the level of WTO, the collection and interpretation of statistical data provided by the WTO Secretariat, the case study, namely the study of literature. The paper is structured in three parts. The first part of the paper examines the basic laws based on which regional trade agreements are notified to the WTO and the evolution of these agreements in the period 1958-2013. The second part of the paper is devoted to the analysis of competition policy in regional trade agreements. In this part of the paper, to highlight the patterns of competition policy adopted under these agreements was analyzed by three case studies of competition policy in the EU, ASEAN and NAFTA. The three case studies have revealed that the three preferential trade agreements present regional competition policies with varying degrees of integration. The most complex form of competition policy is found in the European Union, because we are talking about a centralized model of competition policy. ASEAN presents a partially decentralized model, while NAFTA scrolls with a decentralized model of competition policy. The last part of the paper presents the characteristics of the four models of competition policy identified in the preferential trade agreements in force. It should be emphasized that if the initial preferential trade agreements have not put a great emphasis on the rules of competition policy, practice has shown the importance

    The revolution in biotechnology presents unprecedented opportunities and dangers for the health and well being of mankind. Today, one can plausibly imagine the eradication of many historic diseases. One can also envisage the creation of new diseases that would endanger a substantial proportion of the entire human species. As powerful applications for biotechnology research are identified, appropriate arrangements for managing their extraordinary consequences will inevitably become necessary. This presentation will explore recent efforts to balance science and security policy in the area of advanced biotechnology research. Key developments on the dual-use issue will be discussed, together with a variety of governance options aimed at mitigating the risk from such research. (author)

    Objectives. Vestibular hearing as an auditory sensitivity of the saccule in the human ear is revealed by cervical vestibular evoked myogenic potentials (cVEMPs). The range of the vestibular hearing lies in the low frequency. Also, the amplitude of an auditory brainstem response component depends on the amount of synchronized neural activity, and the auditory nerve fibers' responses have the best synchronization with the low frequency. Thus, the aim of this study was to investigate correlation between vestibular hearing using cVEMPs and neural synchronization via slow wave Auditory Brainstem Responses (sABR). Study Design. This case-control survey was consisted of twenty-two dizzy patients, compared to twenty healthy controls. Methods. Intervention comprised of Pure Tone Audiometry (PTA), Impedance acoustic metry (IA), Videonystagmography (VNG), fast wave ABR (fABR), sABR, and cVEMPs. Results. The affected ears of the dizzy patients had the abnormal findings of cVEMPs (insecure vestibular hearing) and the abnormal findings of sABR (decreased neural synchronization). Comparison of the cVEMPs at affected ears versus unaffected ears and the normal persons revealed significant differences (P < 0.05). Conclusion. Safe vestibular hearing was effective in the improvement of the neural synchronization.

  15. Synchronization of coupled metronomes on two layers

    Coupled metronomes serve as a paradigmatic model for exploring the collective behaviors of complex dynamical systems, as well as a classical setup for classroom demonstrations of synchronization phenomena. Whereas previous studies of metronome synchronization have been concentrating on symmetric coupling schemes, here we consider the asymmetric case by adopting the scheme of layered metronomes. Specifically, we place two metronomes on each layer, and couple two layers by placing one on top of the other. By varying the initial conditions of the metronomes and adjusting the friction between the two layers, a variety of synchronous patterns are observed in experiment, including the splay synchronization (SS) state, the generalized splay synchronization (GSS) state, the anti-phase synchronization (APS) state, the in-phase delay synchronization (IPDS) state, and the in-phase synchronization (IPS) state. In particular, the IPDS state, in which the metronomes on each layer are synchronized in phase but are of a constant phase delay to metronomes on the other layer, is observed for the first time. In addition, a new technique based on audio signals is proposed for pattern detection, which is more convenient and easier to apply than the existing acquisition techniques. Furthermore, a theoretical model is developed to explain the experimental observations, and is employed to explore the dynamical properties of the patterns, including the basin distributions and the pattern transitions. Our study sheds new lights on the collective behaviors of coupled metronomes, and the developed setup can be used in the classroom for demonstration purposes.

  17. Energy Policy is Technology Politics The Hydrogen Energy Case

    2006-01-01

    Germany's energy supply status shows both an accumulation of unsatisfactory sustainabilities putting the nation's energy security at risk, and a hopeful sign: The nation's supply dependency on foreign sources and the accordingly unavoidable price dictate the nation suffers under is almost life risking; the technological skill, however, of the nation's researchers, engineers, and industry materializes in a good percentage of the indigenous and the world's energy conversion technology market. Exemplified with the up and coming hydrogen energy economy this paper tries to advocate the 21. century energy credo: energy policy is energy technology politics! Energy source thinking and acting is 19. and 20. century, energy efficient conversion technology thinking and acting is 21. century. Hydrogen energy is on the verge of becoming the centre-field of world energy interest. Hydrogen energy is key for the de-carbonization and, thus, sustainabilization of fossil fuels, and as a storage and transport means for the introduction of so far un-operational huge renewable sources into the world energy market. - What is most important is hydrogen's thermodynamic ability to exergize the energy scheme: hydrogen makes more technical work (exergy) out of less primary energy! Hydrogen adds value. Hydrogen energy and, in particular, hydrogen energy technologies, are to become part of Germany's national energy identity; accordingly, national energy policy as energy technology politics needs to grow in the nation's awareness as common sense! Otherwise Germany seems ill-equipped energetically, and its well-being hangs in the balance. (author)

  18. The case for policy-relevant conservation science

    Rose, David C

    2015-01-01

    Drawing on the “evidence-based” (Sutherland et al. 2013) versus “evidence-informed” debate (Adams & Sandbrook 2013), which has become prominent in conservation science, I argue that science can be influential if it holds a dual reference (Lentsch & Weingart 2011) that contributes to the needs of policy makers whilst maintaining technical rigor. In line with such a strategy, conservation scientists are increasingly recognizing the usefulness of constructing narratives through which to enhance the influence of their evidence (Leslie et al. 2013; Lawton & Rudd 2014). Yet telling stories alone is rarely enough to influence policy; instead, these narratives must be policy relevant. To ensure that evidence is persuasive alongside other factors in a complex policy-making process, conservation scientists could follow 2 steps: reframe within salient political contexts and engage more productively in boundary work, which is defined as the ways in which scientists “construct, negotiate, and defend the boundary between science and policy” (Owens et al. 2006:640). These will both improve the chances of evidence-informed conservation policy. El Caso para la Ciencia de la Conservación con Relevancia Política Resumen A partir del debate “con base en evidencia” (Sutherland et al. 2013) versus “informado con evidencia” (Adams & Sandbrook 2013), debate que se ha vuelto prominente en la ciencia de la conservación, argumento que la ciencia puede ser influyente si mantiene una referencia dual (Lentsch & Weingart 2011) que contribuya a las necesidades de quienes hacen la política a la vez que mantiene un rigor técnico. En línea con dicha estrategia, los científicos de la conservación cada vez reconocen más la utilidad de construir narrativas con las cuales pueden mejorar la influencia de sus evidencias (Leslie et al. 2013; Lawton & Rudd 2014). Sin embargo, sólo contar historias rara vez es suficiente para influir sobre la política; en su lugar, estas

    Full Text Available Purpose: The main purpose of this study is to perform a treatment planning study on a synchronous bilateral non-small cell lung cancer case using three treatment modalities: uniform scanning proton therapy, RapidArc, and intensity modulated radiation therapy (IMRT. Methods: The maximum intensity projection (MIP images obtained from the 4 dimensional-computed tomography (4DCT scans were used for delineation of tumor volumes in the left and right lungs. The average 4D-CT was used for the treatment planning among all three modalities with identical patient contouring and treatment planning goal. A proton therapy plan was generated in XiO treatment planning system (TPS using 2 fields for each target. For a comparative purpose, IMRT and RapidArc plans were generated in Eclipse TPS. Treatment plans were generated for a total dose of 74 CGE or Gy prescribed to each planning target volume (PTV (left and right with 2 CGE or Gy per fraction. In IMRT and RapidArc plans, normalization was done based on PTV coverage values in proton plans. Results: The mean PTV dose deviation from the prescription dose was lower in proton plan (within 3.4%, but higher in IMRT (6.5% to 11.3% and RapidArc (3.8% to 11.5% plans. Proton therapy produced lower mean dose to the total lung, heart, and esophagus when compared to IMRT and RapidArc. The relative volume of the total lung receiving 20, 10, and 5 CGE or Gy (V20, V10, and V5, respectively were lower using proton therapy than using IMRT, with absolute differences of 9.71%, 22.88%, and 39.04%, respectively. The absolute differences in the V20, V10, and V5 between proton and RapidArc plans were 4.84%, 19.16%, and 36.8%, respectively, with proton therapy producing lower dosimetric values. Conclusion: Based on the results presented in this case study, uniform scanning proton therapy has a dosimetric advantage over both IMRT and RapidArc for a synchronous bi-lateral NSCLC, especially for the normal lung tissue, heart, and

    Malaysia's global, regional and bilateral international health relations are surveyed against the historical backdrop of the country's foreign policy. Malaysia has always participated in multilateral agencies, most notably the World Health Organization, as such agencies are part of the longstanding fabric of "good international citizenship". The threats of infectious diseases to human health and economic activity have caused an intensification and an organizational formalization of Malaysian health diplomacy, both regionally and bilaterally. Such diplomacy has also established a basis for developing a wider set of cooperative relationships that go beyond responding to the threat of pandemics. As Malaysia approaches "developed" status, its health sector is becoming increasingly integrated into the global economy through joint research and development ventures and transnational investment. At the same time, it will have the technological, financial and human resources to play an expanded altruistic role in global and regional health.

    2000-01-01

    Can the economic theory of depletion be reconciled with low petroleum prices? This article uses a revision of the theory, which reflects demand functions that rise in response to increasing world population and income. The magnitude of producers' and consumers' surplus is estimated under both competitive and monopolistic assumptions; the result indicates a present value comparable to or in excess of today's gross world economic product. Game theory suggests a framework that explains the interaction between oil pricing and military policy, and the economic incentives that result in a general pattern of recent market equilibrium crude oil prices often fluctuating with a 15-20 US dollars per barrel range. The analysis concludes that the economic incentives for political instability in the Persian Gulf will increase, and more formal methods of setting the international framework for Persian Gulf oil may be expected.

  3. Aquaculture Land-Use Policy: The Case of Clam Farming in Thaibinh Province, Vietnam

    Directory of Open Access Journals (Sweden)

    Thi Thu Hang NGO

    2016-12-01

    Full Text Available Policy-making and enforcement remains centralized in Vietnam. Policies have been formulated with less scientific and public justification, thus being largely bureaucratic and infeasible, and in many cases, they have created plagues for people at the grass-roots levels. This article focuses on the implementation of policies related to intertidal land-use and supports for clam farming in the Thaibinh province as a case study to explore the impacts of policies on clam farming and farmers. During the period of 2011–2013, provincial policies on intertidal land allocation and technical and financial supports had boosted clam farming development in the province to a surprising extent. Rapid expansion of the clam farming area has created significant consequences for the farming sector, as well as farmer’s lives. However, for the same provincial policies, but with different enforcement, different farming outcomes for clam farmers in the three study communes have resulted. Where farmers had more of a voice and choice in bidding for the intertidal areas they preferred, they faced fewer problems. It is, thus, suggested that a more decentralized policy-making and enforcement are needed, in which more scientific assessment and farmer participation are required to not only make government policy more successful in supporting farmers and achieving their expected outcomes, but also to provide farmers with more room to make their own farming decisions from which farming and marketing risks could be mitigated.

  4. Technology policy and sustainable development: the case of renewable energy

    Wohlgemuth, N.

    2000-01-01

    Policies to address long-term energy concerns include a wide range of initiatives. Taxes can internalise costs; financial mechanisms, including subsidies, can target particularly favourable but otherwise non-competitive investments; regulation can apply standards to raise performance of appliances; information programmes can improve decision making; and R and D can make available new options. The 1987 report of the World Commission on Environment and development, found that 'energy efficiency can only buy for the world to develop 'low-energy-paths' based on renewable sources...'. Although many renewable energy systems are in a relatively early stage of development, they offer the world 'a potentially huge primary energy source, sustainable in perpetuity and available in various forms to every nation on Earth.' It suggested that an R and D programme of renewable energy is required to attain the same level of primary energy that is now obtained from a mix of fossil, nuclear, and renewable energy resources. Since renewable energy contributes to all dimensions of sustainable development, one policy challenge is to ensure that renewable energy has a fair opportunity to complete with other resources required for the provision of energy services, especially on 'liberalised' energy markets. This paper gives an overview of rationales for government intervention in energy-related R and D, and international energy R and D trends. it concludes that the liberalisation of energy markets has an overall negative impact on private sector investments in energy R and D and that without a sustained and diverse programme of energy R and D and implementation, we are crippling our ability to make the necessary improvements in the global energy system, especially in light of sustainable development requirements.

    Full Text Available Abstract Background Malignant transformation of mature cystic teratoma is a rare complication. While any of the constituent tissues of a teratoma has the potential to undergo malignant transformation, squamous cell carcinoma is the most commonly associated malignancy. Renal carcinoid tumors are rare and frequently associated with horseshoe kidney and renal teratoma. Renal teratoma rarely presents together with carcinoid tumor or adenocarcinoma. To the best of our knowledge, there has never been a report of renal teratoma coexisting with both carcinoid tumor and adenocarcinoma. Methods Here, we present a unique and first case of synchronous primary carcinoid tumor and moderately differentiated adenocarcinoma arising within mature cystic teratoma of horseshoe kidney in a 50-year-old female. Lumbar spine X-ray, done for her complaint of progressive chronic low back pain, accidentally found a large calcification overlying the lower pole of the right kidney. Further radiologic studies revealed horseshoe kidney and a large multiseptated cystic lesion immediately anterior to the right renal pelvis with central calcification and peripheral enhancement. She underwent right partial nephrectomy. Results Macroscopically, the encapsulated complex solid and multiloculated cystic tumor with large calcification, focal thickened walls and filled with yellow-tan gelatinous material. Microscopically, the tumor showed coexistent mature cystic teratoma, moderately differentiated adenocarcinoma and carcinoid tumor. Immunohistochemically, alpha-methylacyl-coenzyme A-racemase, calretinin, CD10 and thyroid transcription factor-1 were negative in all the three components of the tumor. The teratomatous cysts lined by ciliated epithelium showed strong staining for cytokeratin 7 and pancytokeratin, and those lined by colonic-like epithelium showed strong staining for CDX2, cytokeratin 20 and pancytokeratin, but both were negative for calretinin.

    Reich, M R

    1995-01-01

    This paper examines the political dynamics of health sector reform in poor countries, through a comparative study of pharmaceutical policy reform in Sri Lanka, Bangladesh, and the Philippines. The paper first reviews five reasons why policy reform is political. It then presents three political economic models of the policy reform process: the political will, political factions, and political survival models. Next, the paper describes the three cases of national pharmaceutical policy reform, and identifies common conditions that made these reforms politically feasible. The paper's analysis suggests that health sector reform is feasible at certain definable, and perhaps predictable, political moments, especially in the early periods of new regimes. The most important and manipulable political factors are: political timing, which provides opportunities for policy entrepreneurs to introduce their ideas into public debate, and political management of group competition, which allows leaders to control the political effects of distributional consequences and protect the regime's stability. A strong and narrow political coalition improves the capacity of political leaders to resist the pressures of concentrated economic costs (both inside and outside national boundaries). The paper argues that for reform to succeed, policy-makers need effective methods to analyze relevant political conditions and shape key political factors in favor of policy reform. The method of Political Mapping is briefly introduced as a technique that can help policy-makers in analyzing and managing the political dimensions of policy reform and in improving the political feasibility of reform.

    2015-01-01

    We review some of the history and early work in the area of synchronization in chaotic systems. We start with our own discovery of the phenomenon, but go on to establish the historical timeline of this topic back to the earliest known paper. The topic of synchronization of chaotic systems has always been intriguing, since chaotic systems are known to resist synchronization because of their positive Lyapunov exponents. The convergence of the two systems to identical trajectories is a surprise. We show how people originally thought about this process and how the concept of synchronization changed over the years to a more geometric view using synchronization manifolds. We also show that building synchronizing systems leads naturally to engineering more complex systems whose constituents are chaotic, but which can be tuned to output various chaotic signals. We finally end up at a topic that is still in very active exploration today and that is synchronization of dynamical systems in networks of oscillators

    2017-05-01

    Anti-smoking campaigns are widely viewed as a success case in public health policy. However, smoking rates continue to vary widely across U.S. states and the success of anti-smoking campaigns is contingent upon states' adoption of anti-smoking policies. Though state anti-smoking policy is a product of a political process, studies of the effect of policies on smoking prevalence have largely ignored how politics shapes policy adoption, which, in turn, impact state health outcomes. Policies may also have different effects in different political contexts. This study tests how state politics affects smoking prevalence both through the policies that states adopt (with policies playing a mediating role on health outcomes) or as an effect modifier of behavior (tobacco control policies may work differently in states in which the public is more or less receptive to them). The study uses publicly available data to construct a time-series cross-section dataset of state smoking prevalence, state political context, cigarette excise taxes, indoor smoking policies, and demographic characteristics from 1995 to 2013. Political ideology is measured using a validated indicator of the ideology of state legislatures and of the citizens of a state. We assess the relationship between state political context and state smoking prevalence rates adjusting for demographic characteristics and accounting for the mediating/moderating role of state policies with time and state fixed effects. We find that more liberal state ideology predicts lower adult smoking rates, but that the relationship between state ideology and adult smoking prevalence is only partly explained by state anti-smoking policies.

    Both public health, and the health of the natural environment, are affected by policy decisions made across portfolios as diverse as finance, planning, transport, housing, education, and agriculture. A response to the interdependent character of public health has been the "health in all policies" (HiAP) approach. With reference to parallels between health and environment, this paper argues that lessons from HiAP are useful for creating a new integrated environmental management approach termed "environment in all polices" (EiAP). This paper covers the theoretical foundations of HiAP, which is based on an understanding that health is strongly socially determined. The paper then highlights how lessons learned from HiAP's implementation in Finland, California, and South Australia might be applied to EiAP. It is too early to learn from evaluations of HiAP, but it is apparent that there is no single tool kit for its application. The properties that are likely to be necessary for an effective EiAP approach include a jurisdiction-specific approach, ongoing and strong leadership from a central agency, independent analysis, and a champion. We then apply these properties to Victoria (Australia) to demonstrate how EiAP might work. We encourage further exploration of the feasibility of EiAP as an approach that could make explicit the sometimes surprising environmental implications of a whole range of strategic policies.

    2008-10-01

    Full Text Available The possibility of a coincidental appearance of hyperparathyroidism and thyroid cancer is not often considered because of its low incidence. Here, we present a case of a 49-year-old woman with a parathyroid adenoma coexisting with two sites of papillary thyroid carcinoma. Dual-phase 99mTc-methoxyisobutylisonitrile (MIBI parathyroid imaging before the operation correctly visualized the site of the parathyroid adenoma. In addition, two papillary thyroid carcinomas showed faint uptake of 99mTc-MIBI on delayed image. Total thyroidectomy and parathyroidectomy of a solitary parathyroid adenoma were performed. The patient subsequently underwent radioiodine-131 ablation and was treated with T4 suppression. This case illustrates the need for clinical awareness of concomitant hyperparathyroidism and thyroid cancer. Dual-phase 99mTc-MIBI parathyroid imaging may be useful for detecting indolent thyroid cancer before it becomes a distinct disease.

    There has been a re-emphasis recently on community health workers to provide child health care services including integrated community case management for childhood illness (iCCM). This research analysed iCCM policy development in Kenya and in particular the types of decision-making criteria used by Kenyan policy-makers in considering whether to advance iCCM policy. Data were collected through document reviews (n = 41) and semi-structured interviews (n = 19) with key stakeholders in iCCM policy including government officials, development partners, bilateral donors, and civil society organizations. Initial analysis was guided by the policy triangle with further analysis of factors affecting policy decision-making drawing upon a simple framework developed by Grindle and Thomas (Policy makers, policy choices and policy outcomes: the political economy of reform in developing countries. 1989; Policy Sci 22: :213-48.). Policy development for iCCM has been slow in Kenya, compared with other Sub-Saharan African countries. At the time of the study, the Government had just completed the Community Health Training Manual which incorporated iCCM as a module, but this was the only formal expression of iCCM in Kenya. We found technical considerations, notably concerns about community health workers dispensing antibiotics to be a key factor slowing iCCM policy development, but this also overlapped with bureaucratic considerations, such as how the development of community health worker cadres may affect clinicians, as well as initial concerns about how an integrated approach might affect vertically oriented programs. International actors through agreements such as the Millennium Development Goals helped to get child survival onto the national policy agenda and such actors were active promoters of iCCM policy change. However international funders had not committed funding to scale-up iCCM policy, and this probably constrained their influence over iCCM policy debate. Kenyan actors

The purpose of the present study is to review the Greek market of generic drugs and the decisions that shape it, to determine the factors that affect Greek patients' and doctors' attitudes about generic substitution and present a set of measures for all stakeholders based on the findings of the secondary and primary analysis. The study includes (a) an analysis of international and national reports and legislation on drugs policies and (b) a questionnaire survey of 242 hospital patients and 85 doctors regarding their perceptions on generics. A small increase in the volume of generics is recorded, yet not followed by sales value, over the recent years that the measures for promoting generics prescription took effect. Distrust from both patients and doctors was observed toward generics' effectiveness and toward the appropriateness of the regulatory authorities' quality controls. The study presents a structured set of viable measures, applicable to many countries, for promoting generic drug consumption that can lead to economic efficiency without degrading the health care quality.

    A plan for actively achieving green energy obligation is a strategic tool for policies that point forward the diminution of the fossil fuel consumption and greenhouse gas (GHG) in conformity with the Paris environment-friendly accords (COP21) and updates of other ecosystem agreements. To achieve the concrete implementation of the sustainable energy strategy (SES) and to accomplish its objectives, an investigation is a critical factor. SES investigation has to consider both the advancement of each particular action and its wide-ranging green effect, which necessitates multiple levels of improvement. In this study, a consolidated eco strategy for evaluating, monitoring and handling the SES via investigation and execution process is established. The city of Nairobi was used as one of the geographical positions to test the effectiveness of this approach and to investigate its robust and weak points. Specifically, benefit-cost analysis, reliability, peer review and general level of participation were renowned as vital tools for attaining a functional SES investigation and for then drafting successful energy guidelines. Some suggestions were put forward to highlight the research and execution methods and to draw a road map of how SES can be strategically placed into practice.

  14. Climate policies in a second-best world-A case study on India

    2010-01-01

    The aim of this article is to analyze the potential for synergies between climate policies and development in a case study on India focusing on the power sector sub-optimalities. To do so, we use IMACLIM-R, a dynamic recursive energy-economy model that represents a second best world with market imperfections and short-run adjustments constraints along a long-term growth path. The analysis suggests (i) global carbon pricing induces prohibitive macroeconomic costs for the Indian economy, even in the case of significant financial transfers associated with a global cap-and-trade system and a 'Contraction and Convergence in 2100' allocation scheme and (ii) the most cost efficient climate policies are not uniform carbon pricing only. The implementation of domestic policies suited to the national context, for instance targeting sub-optimalities in the power sector for India, allows reducing significantly the macroeconomic costs induced by international mitigation policies.

  15. Customs unions, currency crises, and monetary policy coordination: The case of the Eurasian Economic Union

    Full Text Available After achieving substantial progress in establishing a common customs territory and regulations, customs unions face potential disruptions due to a lack of monetary policy coordination. These disruptions might appear in the form of currency shocks and the ensuing trade conflicts. We approach this issue by looking at the case of the Eurasian Economic Union (EAEU. The volatility of national currencies in 2014–2015 resulted in sizable shifts in competitiveness, culminating in a currency crisis in some member states. This raises the questions of how to gradually achieve a more coordinated monetary policy, what monetary policy options are available, and what would be their relative impact on macroeconomic stability. Using a set of modeling tools and econometric models, we review three monetary regimes, which represent moves from fully independent exchange rate policy through increased policy coordination to joint exchange rate setting.

    1981-01-01

    The relationship between policies and the definition of a national program of nuclear energy, is considered. The case under study is the Brazilian one. It is shown that an overall evaluation of market, industry and science and technology is mandatory for the definition of a nuclear energy program, and serious fault and hesitation, leading to contradiction and failure, have their roots in a basic lack of definition in policies. The evolution of the Brazilian Nuclear Energy Program will probably remain at a mediocre level until a definition at the level of policy-making in marketing, industry and science and technology is firmly pursued and maintained.

  19. Improving Patient Safety with X-Ray and Anesthesia Machine Ventilator Synchronization: A Medical Device Interoperability Case Study

    Science.gov (United States)

    Arney, David; Goldman, Julian M.; Whitehead, Susan F.; Lee, Insup

    When a x-ray image is needed during surgery, clinicians may stop the anesthesia machine ventilator while the exposure is made. If the ventilator is not restarted promptly, the patient may experience severe complications. This paper explores the interconnection of a ventilator and simulated x-ray into a prototype plug-and-play medical device system. This work assists ongoing interoperability framework development standards efforts to develop functional and non-functional requirements and illustrates the potential patient safety benefits of interoperable medical device systems by implementing a solution to a clinical use case requiring interoperability.

    2011-01-01

    The authors describe a rare case of metastatic bronchogenic adenocarcinoma in a 55-year-old man presenting with concomittant solitary lytic skull lesion and ischaemic stroke. Metastatic bronchogenic carcinoma is known to present as lytic skull lesions. Primary brain tumours are also known to cause ischaemic brain injury. An underlying stroke risk may be exagerated by cranial tumour surgery. Patients with brain tumours are well known to be predisposed to an increased risk of developing thromboembolic disease. It is unusual to see metastatic bronchogenic adenocarcinoma presenting as ischaemic stroke with a background of concomittant cerebral metastasis. The aetio-pathogenesis of this rare occurrence is discussed with a review of literature.

  1. Metachronous and Synchronous Occurrence of 5 Primary Malignancies in a Female Patient between 1997 and 2013: A Case Report with Germline and Somatic Genetic Analysis

    2017-11-01

    Full Text Available The number of patients with multiple primary malignancies has been increasing steadily in recent years. In the present study, we describe a unique case of an 81-year-old woman with 5 metachronous and synchronous primary malignant neoplasms. The patient was first diagnosed with an endometrium adenocarcinoma in 1997 and a colon adenocarcinoma in 2002. Eleven years after her colon surgery, in 2013, the patient presented with 3 other primary malignancies within a 4-month time span: an invasive malignant melanoma on the lower leg, an invasive mucinous breast carcinoma in the right breast, and a pleomorphic spindle cell sarcoma on the left upper arm. Subsequent routine medical checkups in 2013–2017 revealed no metastases of the primary malignancies. The patient mentioned a familial aggregation of malignant tumors, including 2 sisters with breast cancer and a brother with lung cancer. Interestingly, next-generation sequencing analysis of the patient’s blood sample detected no mutations in the BRCA1, BRCA2, TP53, PTEN, CDH1, PALB2, RAD51C, RAD51D, MLH1, MSH2, MSH6, PMS2, EPCAM, APC, MUTYH, STK11, BMPR1A, SMAD4, PTEN, POLE, POLD1, GREM1, and GALNT12 genes. Therefore, whole genome sequencing is warranted to identify cancer-related genetic alterations in this patient with quintuple primary malignancies.

    An 82-year-old woman presented to our hospital with a complaint of frequent vomiting. She was admitted for intensive examination and treatment. Abdominal computed tomography revealed that her stomach was severely expanded, and the wall of the ascending colon was thickened throughout its circumference. Upper gastrointestinal endoscopy uncovered severe stenosis in the pylorus and an elevated lesion resembling a submucosal tumor on the posterior wall of the pylorus. Biopsies of the lesion revealed that it was of Group 1. On colonoscopy, type 2 cancer was found in the ascending colon throughout the circumference, and the biopsies revealed that it was of Group 5. Upper gastrointestinal endoscopy was repeated, and the same result was obtained. The possibility of malignancy could not be excluded; therefore, distal gastrectomy and right colectomy were performed. In terms of histopathology, both resected specimens displayed poorly differentiated adenocarcinoma; however, immunohistochemical studies revealed differences in staining at the two sites. The case was diagnosed as synchronous double cancer involving gastric cancer resembling a submucosal tumor with stenosis in the pylorus and ascending colon cancer. Gastric cancer resembling a submucosal tumor is usually difficult to diagnose on biopsy. If the endoscopic findings reveal an elevated lesion resembling a submucosal tumor with stenosis, then the possibility of carcinoma should be considered, and the most suitable treatment should be selected.

    Prostate cancer is the second most common cancer in man. It commonly presents with urinary symptoms, bone pain, or diagnosed with elevated prostate-specific antigen.(PSA) levels. Correct staging and early diagnosis of recurrence by a precise imaging tool are the keys for optimum management. Molecular imaging of prostate cancer with Ga-68 prostate-specific membrane antigen.(PSMA), positron emission tomography-computed tomography.(PET-CT) has recently received significant attention and frequently used with a signature to prostate cancer-specific remark. However, this case will highlight the more cautious use of it. A-72-year-old male treated earlier for synchronous double malignancy.(invasive papillary urothelial carcinoma right ureter and carcinoma prostate) presented with rising PSA.(0.51.ng/ml) and referred for Ga-68 PSMA PET-CT, which showed a positive enlarged left supraclavicular lymph node. Lymph node biopsy microscopic and immunohistochemistry examination revealed metastatic carcinoma favoring urothelial origin. Specificity of PSMA scan to prostate cancer has been seen to be compromised in a certain situation mostly due to neoangiogenesis, and false positives emerged in renal cell cancer, differentiated thyroid cancer, glioblastoma, breast cancer brain metastasis, and paravertebral schwannomas. Understanding the causes of false positive will further enhance the confidence of interpretating PSMA scans

    For all governments, the principle of how and whether policies are implemented as intended is fundamental. The aim of this paper is to examine the difficulties for governments in delivering policy goals when they do not directly control the processes of implementation. This paper examines two case studies – anti-social behaviour and street crime – and demonstrates the difficulties faced by policy-makers in translating policy into practice when the policy problems are complex and implementation involves many actors.

  5. Relationship Between Energy Prices, Monetary Policy and Inflation; A Case Study of South Asian Economies

    Full Text Available Monetary policy tools, including money supply and interest rate, are the most popular instruments to control inflation around the globe. It is assumed that a tight monetary policy, either in form of reduction in money supply or an increase in interest rate, will reduce inflation by reducing aggregate demand in an economy. However, monetary policy could be counterproductive if cost side effects of monetary tightening prevail. High energy prices may increase the cost of production by reducing aggregate supply in the economy. If tight monetary policy is used to reduce this cost push inflation, the cost side effect of energy prices will add to cost side effects of monetary tightening and will become dominant. In this case, the monetary policy could be counterproductive. Furthermore, simultaneous reduction in aggregate supply and aggregate demand will bring twofold reduction in output. Therefore greater care is needed in the use of monetary policy in the situation of cost push inflation. This article investigates the presence of cost side effect of monetary transmission mechanism, the role of international oil prices in domestic inflation, and implications for monetary policy. The findings suggest that both monetary policy and oil prices have cost side effects on inflation and monetary tightening could be counterproductive if used to reduce energy pushed inflationary trend.

  6. Efficacy of sorafenib in BRAF-mutated non-small-cell lung cancer (NSCLC) and no response in synchronous BRAF wild type-hepatocellular carcinoma: a case report

    Sorafenib is a multi-targeted kinase inhibitor with a demonstrated activity in renal cell carcinoma (RCC) and hepatocellular carcinoma (HCC), and it is currently used for the treatment of these pathologies. Ongoing clinical trials are studying its activity in other malignancies, such as non-small-cell lung cancer (NSCLC). However, no biological marker is known to define either the sensitivity or resistance to the drug. Here we report a case of a patient with two synchronous tumors, HCC and NSCLC, with metastases in the contralateral lung and bone. The patient was treated with gemcitabine as first line, with a resulting progressive disease after two months, and then with sorafenib at standard dosage in the second line setting. After 6 months of treatment CT scan showed a partial response in the primary lesion of the lung, complete response of the metastasis in the contralateral lung, and stability of HCC. The patient had progression in the lung, liver and bone after 13 months of therapy. A molecular characterization of NSCLC and HCC lesions was performed, revealing a BRAF exon 11 mutation (G469V) only in NSCLC. We hypothesize that the response observed in NSCLC lesions could be due to the presence of BRAF mutation, and that this alteration could be responsible in determining sorafenib sensitivity. Results observed in this case encourage further research on the activity of sorafenib in both HCC and NSCLC, based on the presence of BRAF mutation. This could lead to a selection of HCC patients to be treated with this drug, and could help identify a novel treatment strategy for BRAF-mutated NSCLC patients

    Aims Local alcohol policies can be effective in reducing alcohol-related harm. The aim of this study was to examine local government responses to alcohol-related problems and identify factors influencing their development and adoption of alcohol policy. Designsettings and participants Case studies were used to examine local government responses to alcohol problems in three New Zealand communities: a rural town, a provincial city and a metropolitan city. Newspaper reports, local government documents and key informant interviews were used to collect data which were analysed using two conceptual frameworks: Kingdon's Streams model and the Stakeholder model of policy development. Measurements Key informant narratives were categorized according to the concepts of the Streams and Stakeholder models. Findings Kingdon's theoretical concepts associated with increased likelihood of policy change seemed to apply in the rural and metropolitan communities. The political environment in the provincial city, however, was not favourable to the adoption of alcohol restrictions. The Stakeholder model highlighted differences between the communities in terms of power over agenda-setting and conflict between politicians and bureaucrats over policy solutions to alcohol-related harm. These differences were reflected in the ratio of policies considered versus adopted in each location. Decisions on local alcohol policies lie ultimately with local politicians, although the policies that can be adopted by local government are restricted by central government legislation. Conclusions The adoption of policies and strategies to reduce alcohol-related harm may be better facilitated by an agenda-setting process where no ‘gate-keepers’ determine what is included into the agenda, and community mobilization efforts to create competitive local government elections around alcohol issues. Policy adoption would also be facilitated by more enabling central government legislation. PMID:23130762

    The study of network synchronization has attracted increasing attentionrecently. In this paper, we strictly define a class of networks, namely effective networks, which are synchronizable and orientable networks. We can prove that all the effective networks with the same size have the same spectra, and are of the best synchronizability according to the master stability analysis. However, it is found that the synchronization time for different effective networks can be quite different. Further analysis shows that the key ingredient affecting the synchronization time is the maximal depth of an effective network: the larger depth results in a longer synchronization time. The secondary factor is the number of links. The increasing number of links connecting nodes in the same layer (horizontal links) will lead to longer synchronization time, whereas the increasing number of links connecting nodes in neighboring layers (vertical links) will accelerate the synchronization. Our analysis of the relationship between the structure and synchronization properties of the original and effective networks shows that the purely directed effective network can provide an approximation of the original weighted network with normalized input strength. Our findings provide insights into the roles of depth, horizontal and vertical links in the synchronizing process, and suggest that the spectral analysis is helpful yet insufficient for the comprehensive understanding of network synchronization.

    2010-01-01

    Climate change is a topic of increasing interest to contemporary decision makers. In order for governments to make informed decisions in climate change mitigation and adaptation efforts, environmental policy makers require strong research and analytical capabilities to design and implement effective policies to deal with wide-ranging and complex policy issues. This articles presented a 7-criteria model of policy analytical capacity (PAC) and applied it to 3 prominent Canadian environmental policy research organizations. The 2 governmental organizations examined in this study were Environment Canada and the British Columbia Ministry of the Environment, while the non-government organization was the David Suzuki Foundation. Following the 7 principles that determine the PAC of an organization, each case study examined the education/training of the organization's employees; the types and mix of policy analysis techniques used by the organization; the culture and structure of decision making in the organization; the nature and source of demand for the organization's research; and the organization's access to necessary data and information to conduct work at a high level of competence. Interview data provided information on the status of each organizations' current research capacity and the effect this has on overall government policy-making capability in the face of climate change challenges. 75 refs.

    In this article we analyse how interculturalism, intended as a new paradigm of immigrant integration policies, has been taking shape in an Italian city, i.e. Turin, in the context of the current economic crisis. We argue for the necessity of going beyond official statements on intercultural policy by undertaking a comparative analysis of policy practices in three Neighbourhood Houses (NHs, Case del quartiere ), which are defined by the Municipality as open and intercultural spaces in which associations and citizens can develop activities aimed at expressing different cultural backgrounds, fostering participation and supporting social inclusion. The study shows how the three NHs pursue different approaches - social, cultural or more political - to interculturalism, somewhat reflecting the social and structural context in which the three NHs were established, as well as problem definitions and policy frames of the founding organisations.

    Policy entrepreneurs are individuals who attempt to influence the policy process and its outcomes through their opportunistic or incremental actions. Their success in the policy-making process has been associated with the convergence of four factors: behavioural traits; institutional factors; network position and political capital. Policy entrepreneurs have received little study in low- and middle-income country policy research despite observations of individualized decision-making, informal institutions and the unequal distribution and exercise of power in policymaking. This article aims to identify whether policy entrepreneurs were present in the policy process around integrated community case management (iCCM) in Burkina Faso, whether they were successful in achieving policy change, and whether success or failure can be explained using existing policy entrepreneur frameworks from high-income polities. This mixed methods policy study collected data from in-depth qualitative interviews and social network surveys of actors involved in iCCM policymaking [known locally as C-integrated management of childhood illness (IMCI)]; data were analysed based on the framework categories. Interview data pointed to one key individual who played a significant role in the inclusion of pneumonia treatment into the country's iCCM policy, an issue that had been a point of contention between government policy elites and development partners. Social network data confirmed that this actor was strategically located in the policy network to be able to reach the most other actors and to be able to control the flow of information. Although some development partner actors were as strategically located, none had the same level of authority or trust as was imbued by being a member of the government civil service. The entrepreneur's mid-level rank in the health ministry may have encouraged him/her to invest political capital and take risks that would not have been feasible or attractive to a

Although some development partner actors were as strategically located, none had the same level of authority or trust as was imbued by being a member of the government civil service. The entrepreneur’s mid-level rank in the health ministry may have encouraged him/her to invest political capital and take risks that would not have been feasible or attractive to

    This paper studies pinning-controlled synchronization of complex networks with bounded or unbounded synchronized regions. To study a state-feedback pinning-controlled network with N nodes, it first converts the controlled network to an extended network of N+1 nodes without controls. It is shown that the controlled synchronizability of the given network is determined by the real part of the smallest nonzero eigenvalue of the coupling matrix of its extended network when the synchronized region is unbounded; but it is determined by the ratio of the real parts of the largest and the smallest nonzero eigenvalues of the coupling matrix when the synchronized region is bounded. Both theoretical analysis and numerical simulation show that the portion of controlled nodes has no critical values when the synchronized region is unbounded, but it has a critical value when the synchronized region is bounded. In the former case, therefore, it is possible to control the network to achieve synchronization by pinning only one node. In the latter case, the network can achieve controlled synchronization only when the portion of controlled nodes is larger than the critical value. (general)

    2017-07-01

    Full Text Available The world decided in December 2015 to take actions to reduce global warming. To contribute toward this goal, this research examines possible policy levers for inclusion in the climate change ratification plan. A case study of the measures taken by the Republic of Singapore, a low-lying 719.2 km2 island without natural resources in Asia, is conducted. Being vulnerable to climate change impact and yet having to balance her people’s needs and economic progress with limited resources, the measures taken by this small country could offer policy insights for small states and states without access to alternative energy sources. This research analyzes the online policy documents posted by eleven organizations to answer the main research question of identifying policy levers as theoretical constructs to form a framework that can be used to study climate change policies. A qualitative data analysis software, QSR NVivo 10, is used to classify the proposed nodes developed by the researchers using a system perspective integrating the insights from the key international climate change frameworks with the theoretical concepts from the model of pro-environmental behavior. The findings can offer insights toward developing a new contextual influence framework, which can help strengthen policy development and outcome measurement.

  10. Evidence-based policy learning: the case of the research excellence indicat

    2016-07-01

    Excellence is arguably the single most important concept in academia today, especially when it comes to science policy making. At the same time, however, excellence leads to a great amount of discomfort, leading some to plea for an overall rejection of the concept. The discomfort with excellence reaches its heights whenever proposals are made for measuring it. Yet, especially given the period of professionalization science policy making finds itself in, these same metrics are frequently called upon to legitimate policy interventions. Excellence and its measurement, it seems therefore, is something we can neither life with nor without. This paper offers some middle ground in the debate on excellence and its measurement for science policy purposes. Using the case of the European Commission’s Research Excellence Indicator as an example, we show how the development and use of indicators offers an opportunity for learning in science policy making. Ultimately, therefore, we show how and in what ways measuring excellence can contribute to evidence-based science policy learning in practice. (Author)

  11. When should green technology support policies supplement the carbon price? The case of the electricity sector

    International Nuclear Information System (INIS)

    Lecuyer, Oskar

    2013-01-01

    This thesis contributes to the literature on optimal policy choice. It studies the use of policy combinations to mitigate greenhouse gases emissions from electricity production. One finding applies to cases where uncertainty is such that the risk of a nil carbon price cannot be excluded. A cap on emissions alone may then not trigger enough abatements, justifying the addition of e.g. a renewable subsidy. When considering a transition toward a carbon free electricity sector, capital accumulation causes complex dynamic effects to happen. We find that decisions taken by comparing the leveled costs of abatement technologies, even including carbon costs, would favor intermediate technologies (e.g. gas plants) to the detriment of more-expensive but lower-carbon technologies (renewable power), leading to a suboptimal investment schedule. This thesis also studies the effects of marginal policy changes in a mix comprising the main French instruments. We find that surprisingly, adding a tariff for renewables financed by a tax on electricity consumption to a cap on emissions and a subsidy for energy efficiency will reduce the consumer electricity price when the non-renewable production is fixed and does not depend on the carbon price. The assessment of the French climate policies in the electricity sector shows that overlapping policies for mitigation may be justified by multiple carbon price failures, even if the ideal long-term policy mix depends on the carbon price trajectory.

  12. The policies-inequality feedback and health: the case of globalisation.

    2009-09-01

    Major research contributions aimed at explaining the association between economic inequality and health have concentrated on the plausibility of the material deprivation and psychosocial factors pathways. However, little work has analysed the reciprocal associations between public policies and inequality and their effect on health. A conceptual framework was first proposed explaining how the public policies-inequality feedback can influence health outcomes via material deprivation and psychosocial factors. Then, a critical review of the literature was conducted and an analysis of the health effects of the globalisation-inequality feedback as a case study. Different bodies of evidence seem to give support to the hypothesis of a public policies-inequality feedback influencing health-related outcomes. This seems to be particularly true when considering globalisation policies. Since the widespread adoption of the so-called "Washington Consensus", economic inequalities have sharply increased worldwide. The rise in inequality has, in turn, further consolidated the adoption of these policies through an increasing "democratic deficit". The reciprocal effects of globalisation and inequality have produced adverse health outcomes between and within societies through both material deprivation and psychosocial stress. Public policies and economic inequality are inextricably interrelated and can affect health through multiple, indirect, reciprocal pathways.

    Responsible governance is crucial to national development and a catalyst for achieving the Millennium Development Goals. To date, governance seems to have been a neglected issue in the field of human resources for health (HRH), which could be an important reason why HRH policy formulation and implementation is often poor. This article aims to describe how governance issues have influenced HRH policy development and to identify governance strategies that have been used, successfully or not, to improve HRH policy implementation in low- and middle-income countries (LMIC). We performed a descriptive literature review of HRH case studies which describe or evaluate a governance-related intervention at country or district level in LMIC. In order to systematically address the term 'governance' a framework was developed and governance aspects were regrouped into four dimensions: 'performance', 'equity and equality', 'partnership and participation' and 'oversight'. In total 16 case studies were included in the review and most of the selected studies covered several governance dimensions. The dimension 'performance' covered several elements at the core of governance of HRH, decentralization being particularly prominent. Although improved equity and/or equality was, in a number of interventions, a goal, inclusiveness in policy development and fairness and transparency in policy implementation did often not seem adequate to guarantee the corresponding desirable health workforce scenario. Forms of partnership and participation described in the case studies are numerous and offer different lessons. Strikingly, in none of the articles was 'partnerships' a core focus. A common theme in the dimension of 'oversight' is local-level corruption, affecting, amongst other things, accountability and local-level trust in governance, and its cultural guises. Experiences with accountability mechanisms for HRH policy development and implementation were lacking. This review shows that the term

    2017-01-01

    Despite its high potential to support decision-making, the role of policy assessment in real-world policy making in the field of poverty and social inequalities remains largely questioned. In this study, we analyse policy assessment's role in a context of real-world policymaking, by means of a case study on a legislative proposal on integration policy for immigrant newcomers in the Brussels-Capital Region, for which we evaluate the potential effects on poverty and social inequalities. We first analyse the policy process surrounding the policy proposal – a process that is often treated as a black box within policy assessment research. Understanding the factors that influence and determine the decision-making process, enables us to gain insight into the potential decision-support function(s). Second, we develop an approach to policy assessment that aims to fully exploit its potential to contribute to the functions of both instrumental and conceptual learning. For this purpose, we propose to introduce the approach of realist evaluation and to focus on evaluating the underlying policy intervention theory from the perspective of poverty and social inequalities. Finally, we illustrate this new approach and its added value by applying it to the legislative proposal on integration policy and analyse its contribution to policy-oriented learning. - Highlights: •The field of policy assessment should draw on insights from policy studies. •We unpacked the policymaking black-box to identify the mechanisms of policy change. •The policy process is driven by an interaction of ideas, interests and institutions. •Policy assessment's potential lies in both instrumental and conceptual learning. •We propose to integrate realist evaluation's logic of inquiry within policy assessment.

  18. The Role of Sub-National Actors in Climate Change Policy. The Case of Tokyo

    International Nuclear Information System (INIS)

    Roppongi, Hitomi

    2016-06-01

    Tokyo is known as a pioneer throughout the history of Japan's environmental policy, often being compared to California in the United States or Paris in France. Following the global trend of growing local initiatives tackling climate change, Tokyo introduced a cap-and-trade scheme in 2010 ahead of a national implementation. The Tokyo Cap-and-Trade Program is the first of its kind that regulates CO_2 emissions from all business sectors, where energy consumers are defined in terms of the business establishments they own. Tokyo's initiative is largely seen as a reaction to the modest national commitment, following the tradition of center-local rivalry. This study first explains the centre-local relationship in the history of Japan's environmental governance. It then analyzes the development of the Tokyo's flagship climate policy and its implications for national and other sub-national governments in Japan. The tactics used by the Tokyo Metropolitan Government to overcome business opposition typically seen in the introduction of GHG control, and future policy challenges are also discussed. The study finds that Tokyo's policy encourages behavioral changes and technological improvement in the business sector, going a step beyond the existing culture of energy conservation in Japan. An emission trading scheme is often associated with the collapse of carbon markets and the 'money game', rather than a practical tool to reduce CO_2 emissions, but the Tokyo Cap-and-Trade Program has demonstrated a policy impact that recasts such an image. A known case of policy diffusion to Saitama prefecture, an immediate neighbor of Tokyo with the fifth largest population in Japan, is also discussed to elaborate on the potential domestic diffusion of the policy.

    2017-03-01

    Full Text Available The tax policy assessment is an indispensable strategy within any modern country’s system of governance. There are several types of “impact assessments”, with RIA as one of the most commonly used. This tool is used to measure and analyse the benefits, costs and effects of a new or existing legal regime, which can be carried out by collecting and analysing empirical data in the context of a broader decision-making framework. The main objective of the paper is to analyse which stage the Slovenian regulatory impact assessment is in, and whether this stage is sophisticated enough to provide for the essential verification of tax policy and specific instruments, focusing mainly on the case of interest tax shield issues. Methodologically, the paper is based on a systematic literature review, a survey for public consultations and statistical tools for calculating the differences in internal indebtedness in different observed periods. The results show that the Slovenian RIA is not sophisticated enough to evaluate complex tax instruments and policy. Nevertheless, tax policy decision-makers should reconsider the implementation of a thin capitalization rule (but also future tax policy instruments focusing also on other, non-tax revenue, factors.

    The cumulative total of persons forced to leave their country for fear of persecution or organized violence reached an unprecedented 24.5 million by the end of 2015. Providing equitable access to appropriate health services for these highly diverse newcomers poses challenges for receiving countries. In this case study, we illustrate the importance of translating epidemiology into policy to address the health needs of refugees by highlighting examples of what works as well as identifying important policy-relevant gaps in knowledge. First, we formed an international working group of epidemiologists and health services researchers to identify available literature on the intersection of epidemiology, policy, and refugee health. Second, we created a synopsis of findings to inform a recommendation for integration of policy and epidemiology to support refugee health in the United States and other high-income receiving countries. Third, we identified eight key areas to guide the involvement of epidemiologists in addressing refugee health concerns. The complexity and uniqueness of refugee health issues, and the need to develop sustainable management information systems, require epidemiologists to expand their repertoire of skills to identify health patterns among arriving refugees, monitor access to appropriately designed health services, address inequities, and communicate with policy makers and multidisciplinary teams.

    2018-02-01

    This study introduces a new research topic that investigates the relationship between fiscal development and carbon emissions in Turkey through testing Environmental Kuznets Curve (EKC) hypothesis. Annual data covering the period, 1960-2013, has been used and in addition to gross domestic product and energy consumption, fiscal policy variables have been regressed on the level of carbon emissions in Turkey. Results reveal that fiscal policies and carbon emissions are in long-term equilibrium relationship in Turkey; carbon dioxide emission level converges towards long-term paths as contributed by fiscal policy. The effects of fiscal aggregates on the level of carbon dioxide emissions are negatively significant revealing that growth in fiscal aggregates leads to declines on the levels of carbon emissions. This proves that as far as environmental effects are concerned, fiscal policies regarding energy sector is successful in Turkey. Thus, the major finding of this study confirmed the validity of the fiscal policy-induced EKC hypothesis in the case of Turkey.

    Linking sound scientific data and conclusions to decision and policy support is not a trivial task, and the difficulty in achieving this has been highlighted more than a decade ago (Reid, 2004). There are several reasons why this is the case, inter alia: 1. The language, (vocabularies, framework, and heuristics) adopted by the research community in a specific discipline may not translate into meaningful implementation language (Preston et al., 2015); 2. The researchers may not be in a position of influence (which includes aspects such as writing policy briefs, undertaking personal initiatives, and building up public or industry concern and interest) (Fox and Sitkin, 2015); 3. The frequency, timing, and/or certainty associated with research output is at odds with decision and policy-making cycles. Research typically progresses until there is a defensible level of certainty in statistical assessment of a result, while policy decisions are often made within a regular cycle; 4. Scientists are not trained for, or measured by, the typical work required for decision and policy support: synthesis of scenarios and cost-benefits of such scenarios given sometimes significant uncertainty in the input data, and cross-disciplinary concerns that need to be balanced. There is a significant expectation that research output, being increasingly open, standardised, and managed in formal research data infrastructure, will be useful to policy and decision makers without much additional intervention and modification. We believe that this is unlikely to be feasible in the majority of cases. For most instances, it will be necessary to provide a framework for the translation of scientific output into decision and policy support metrics or indicators at a frequency, with spatial and temporal resolution, and thematic coverage that suits the decision to be made. Such frameworks exist, since the need has been identified - sometimes formally - such as the very detailed framework developed by

    Synchronization processes in populations of locally interacting elements are in the focus of intense research in physical, biological, chemical, technological and social systems. The many efforts devoted to understand synchronization phenomena in natural systems take now advantage of the recent theory of complex networks. In this review, we report the advances in the comprehension of synchronization phenomena when oscillating elements are constrained to interact in a complex network topology. We also overview the new emergent features coming out from the interplay between the structure and the function of the underlying pattern of connections. Extensive numerical work as well as analytical approaches to the problem are presented. Finally, we review several applications of synchronization in complex networks to different disciplines: biological systems and neuroscience, engineering and computer science, and economy and social sciences.

    1999-07-01

    Four countries, Botswana, Cote d'Ivoire, Ghana and Zimbabwe, were chosen as cases to study the impact of national health policies on national health status in sub-Saharan Africa. Through a conceptual framework that covers health problem identification, policy formulation and implementation procedures, the study examined national translations of Primary Health Care (PHC) and Health for All by the Year 2000 (HFA/2000) strategies. A series of government measures, taken between 1980-1986 for health policy development and implementation in these countries, were treated as policy determinants of national health outcomes for the period ending 1990. The impact of these determinants on national health status was then analyzed through a comparative description and documentation of observable patterns and trends in infant mortality rates (IMR), under-5 mortality rates (U5MR) and life expectancy. Policy guidelines from PHC and HFA/2000 were used in conjunction with the respective per capita Gross National Products to categorize the four cases. Based on these guidelines, Botswana was ranked high, both in terms of policy development and the level of economic development, while Zimbabwe ranked high in terms of policy development but relatively low in economic terms. Cote d'Ivoire ranked high on economic development but low with regard to its policy framework. Ghana was at the other end of the spectrum, ranking low both in terms of its policy development and its economic performance. The comparative analysis revealed that Botswana and Zimbabwe performed better than Cote d'Ivoire and Ghana on the three outcome indicators. Despite Cote d'Ivoire's superior level of economic development, its health status fell behind that of Zimbabwe and even Ghana. The study concluded that policies formulated and implemented in accordance with key PHC principles could account for improvements in national health status. Since the end of the study period (1990), there have been significant political

    Several countries have developed policies that restrict or limit duration of stay, clinical privileges or the number of residency permits allocated to migrating physicians. Switzerland is currently preparing a new law limiting overall foreign immigration. The impact of such restrictive policies is currently unknown. In a case study of anaesthesia care in Switzerland we modelled, trends in the size of physicians' workforce until 2024, following the implementation of a strict quota policy for foreign medical trainees. We developed a computer-based Markov model with Monte-Carlo simulations to project, in the context of a strict quota policy for foreign trainees, supply and demand for anaesthesia positions until 2024. We used data from a cross-sectional study performed in the French- and Italian-speaking cantons of Switzerland and the Health dataset from the OECD. With 8 to 12 (95% CI 4-20) anaesthetists retiring per year, the implementation of strict quotas of foreign graduates would result in a 38% decrease in the number of anaesthetists in intermediary (senior registrars) positions by 2024. This decrease would be particularly important in district hospitals where nearly half (49%) of the non-Swiss anaesthetists are practising. Swiss graduates are unlikely to balance the shortage. Despite efforts by Swiss universities to increase the number of medical graduates, their number has dropped from 10.5 to 9.7/100 000 inhabitants between 2000 and 2012, due to the growth of the population. This case study in Latin Switzerland shows that a restrictive policy limiting foreign immigration of trainees would result in a major deficit in the number of anaesthetists available to meet population needs. These aspects should be carefully considered when countries develop restrictions and limitations of foreign immigration.

    Full Text Available Abstract Intussusception is uncommon in adults. To our knowledge, synchronous colocolic intussusceptions have never been reported in the literature. Here we described the case of a 59-year-old female of synchronous colocolic intussusceptions presenting as acute abdomen that was diagnosed by CT preoperatively. Laparotomy with radical right hemicolectomy and sigmoidectomy was undertaken without reduction of the invagination due to a significant risk of associated malignancy. The final diagnosis was synchronous adenocarcinoma of proximal transverse colon and sigmoid colon without lymph nodes or distant metastasis. The patient had an uneventful recovery. The case also emphasizes the importance of thorough exploration during surgery for bowel invagination since synchronous events may occur.

  11. How the global and national levels interrelate in climate policymaking: Foreign Policy Analysis and the case of Carbon Capture Storage in Norway's foreign policy

    2016-01-01

    States struggle to develop adequate climate change mitigation policies, especially when national energy interests conflict with collective environmental concerns. It is therefore crucial to understand how viable solutions may find political support on these terms. As one such case, this paper examines Norway's explicit foreign policy to promote Carbon Capture and Storage (CCS) as a mitigation measure. I suggest that a Foreign Policy Analysis framework with a norm-centered constructivist focus allows for new insights into how climate policies function as balancing strategies between external normative pressures and important domestic concerns. It reveals how Norway's CCS policy represents an extraordinary effort to bridge seemingly contradictory agendas. The Norwegian CCS case highlights how a state may engage in innovative foreign political engineering to promote solutions to its international climate commitments on terms that fit national energy needs. It shows that climate political success may depend on successfully linking the international and domestic levels by simultaneously appealing to established norms within each system. - Highlights: • A Foreign Policy Analysis framework is used to explain foreign policy in the energy-climate domain. • Norway's external strategy to promote CCS globally is traced and explained. • Both external and domestic factors influenced Norway's CCS policymaking. • Both ideational and material factors were important to legitimize this strategy.

    2018-02-01

    In this study we aimed to analyze gender health equity as a case of how social policy contributes to population health. We analyzed three sets of social-investment policies implemented in Europe and previously hypothesized to reduce gender inequity in labor market outcomes: childcare; active labor market programs; and long-term care. We use 12 indicators of social-investment policies from the OECD Social Expenditure Database, the OECD Family Database, and the Social Policy Indicators' Parental Leave Benefit Dataset. We draw outcome data from the 2015 Global Burden of Disease for years lived with disability and all-cause mortality among men and women ages 25-54 for 18 European nations over the 1995-2010 period. We estimate 12 linear regression models each for mortality and morbidity (i.e. years lived with disability), one per social-investment indicator. All models use country fixed-effects and cluster-robust standard errors. For years lived with disability, women benefit more from social investment for most indicators. The only exception is the percentage of young children in publicly funded childcare or schooling, which equally benefits men. For all-cause mortality, men benefit more or equally from social investment for most indicators, while women benefit more from government spending on direct job creation through civil employment. Social policy contributes to the distribution of population health. Social-investment advocates argue such policies in particular enhance economic gender equity. Our results show that these polices have ambiguous effects on gender health equity and even differential improvements among men for some outcomes.

    Full Text Available Abstract Objectives To review and assess (i the factors that facilitate the development of sustainable health policy analysis institutes in low and middle income countries and (ii the nature of external support for capacity development provided to such institutes. Methods Comparative case studies of six health policy analysis institutes (3 from Asia and 3 from Africa were conducted. In each region an NGO institute, an institute linked to government and a university based institute were included. Data collection comprised document review, semi-structured interviews with stakeholders and discussion of preliminary findings with institute staff. Findings The findings are organized around four key themes: (i Financial resources: three of the institutes had received substantial external grants at start-up, however two of these institutes subsequently collapsed. At all but one institute, reliance upon short term, donor funding, created high administrative costs and unpredictability. (ii Human resources: the retention of skilled human resources was perceived to be key to institute success but was problematic at all but one institute. In particular staff often moved to better paid positions elsewhere once having acquired necessary skills and experience, leaving remaining senior staff with heavy workloads. (iii Governance and management: board structures and roles varied according to the nature of institute ownership. Boards made important contributions to organizational capacity through promoting continuity, independence and fund raising. Routine management systems were typically perceived to be strong. (iv Networks: linkages to policy makers helped promote policy influences. External networks with other research organizations, particularly where these were longer term institutional collaborations helped promote capacity. Conclusions The development of strong in-country analytical and research capacity to guide health policy development is critical, yet

  14. Urban Containment Policies and the Protection of Natural Areas: The Case of Seoul's Greenbelt

    Full Text Available Countries around the world have responded to the problems associated with rapid urban growth and increasingly land-consumptive development patterns by creating a wide range of policy instruments designed to manage urban growth. Of the array of growth management techniques, urban containment policies are considered by some to be a promising approach. This paper focuses on greenbelts, the most restrictive form of urban containment policy. The long-standing greenbelt of Seoul, Republic of Korea is examined as a case study. Seoul's greenbelt has generated both significant social costs and benefits. Costs include higher land and housing prices in the urban area surrounded by the greenbelt, additional costs incurred by commuters who live beyond the greenbelt and work in Seoul, and increased congestion and related quality of life impacts. Benefits include the amenity value of living near the greenbelt, recreational resources, bequest and heritage values, fiscal savings due to increased efficiency in the provision of public services and infrastructure, and a wide range of life-supporting ecosystem services. After standing virtually unchanged for almost three decades, Korea's greenbelt policy is currently being revised and weakened, largely due to pressure from greenbelt landowners and developers. Although there is no definitive answer to the question of whether Seoul would be a more or less "sustainable city" today without the greenbelt, it is certain that in the absence of the greenbelt, Seoul would have lost much of its rich natural heritage and essential ecosystem services.

    To learn how the local context may affect a city's ability to regulate alcohol products such as high-alcohol-content malt liquor, a beverage associated with heavy drinking and a spectrum of nuisance crimes in urban areas. An exploratory, qualitative case study comparing cities that adopted policies to restrict malt liquor sales with cities that considered, but did not adopt policies. Nine large U.S. cities in seven states. City legislators and staff, alcohol enforcement personnel, police, neighborhood groups, business associations, alcohol retailers, and industry representatives. Qualitative data were obtained from key informant interviews (n = 56) and media articles (n = 360). The data were coded and categorized. Similarities and differences in major themes among and across Adopted and Considered cities were identified. Cities faced multiple barriers in addressing malt liquor-related problems, including a lack of enforcement tools, alcohol industry opposition, and a lack of public and political will for alcohol control. Compared to cities that did not adopt malt liquor sales restrictions, cities that adopted restrictions appeared to have a stronger public mandate for a policy and were less influenced by alcohol industry opposition and lack of legislative authority for alcohol control. Strategies common to successful policymaking efforts are discussed. Understanding the local context may be a critical step in winning support for local alcohol control policies.

    Mitigation of climate change requires action at all the different levels, from the international to the national and the local levels. This contribution presents a case study of the city of Helsinki in Finland. An ex-post approach is used to follow the implementation of the EU directives to the national and further to the city level and to identify the relevant voluntary action taken in the city. We find that the coherence of national and city level policies is the highest in regulated areas, such as waste management and building regulation. Voluntary action is easily taken at local level in areas where co-benefits can be expected: e.g. energy conservation and biofuels for transportation. These voluntary actions can show the feasibility of certain measures which can later on be implemented at national or supranational level. We observe a clear contradiction between the EU and national renewable electricity targets and the nonaction at the city level: local conditions and private interests pose barriers to the implementation of a climate policy. We conclude that the coherence between policies at different levels develops over time and international requirements as well as local conditions can be drivers for it. Cities in particular play a role in mitigating climate change through removing barriers for the implementation of national and EU policies, and through moving forward with and promoting innovative voluntary measures, e.g. through international city networks

  17. Policy Mixes to Achieve Absolute Decoupling: A Case Study of Municipal Waste Management

    Full Text Available Studying the effectiveness of environmental policies is of primary importance to address the unsustainable use of resources that threatens the entire society. Thus, the aim of this paper is to investigate on the effectiveness of environmental policy instruments to decouple waste generation and landfilling from economic growth. In order to do so, the paper analyzes the case study of the Slovakian municipality of Palarikovo, which has drastically improved its waste management system between 2000 and 2012, through the utilization of differentiated waste taxes and awareness-raising and education campaigns, as well as targeting increased recycling and municipal composting. We find evidence of absolute decoupling for landfilled waste and waste generation, the latter being more limited in time and magnitude. These policy instruments could therefore play an important role in municipalities that are still lagging behind in waste management. More specifically, this policy mix was effective in moving away from landfilling, initiating recycling systems, and to some extent decreasing waste generation. Yet, a more explicit focus on waste prevention will be needed to address the entirety of the problem effectively.

    Minas Gerais started the development of the Minas Gerais Health Promotion Policy (POEPS-MG) based on the review of the National Health Promotion Policy (PNPS). This is a case report based on the documentary analysis of the material produced in the 38 workshops with a participation of 1.157 members across the State. The first workshop was intrasectoral and took place at the State Health Secretariat (SDH-MG). The second was an intersectoral workshop with the participation of several State Health Secretariats of Minas Gerais. The final workshop counted on the participation of State Regional Technical References. Another 35 workshops were developed in the 28 State Regional Administrations. Results were systematized and consolidated from the Analytical Matrix used in the PNPS, generating the base document of the POEPS-MG. It is important to highlight that, the specific regional requirements identified during the Policy's construction process reinforce the enriching moments of developing in an innovative, democratic and participative way actions that may provide some meanings to Health Promotion in the State of Minas Gerais. The State Policy seeks to bring life to the PNPS, adapting it to the reality of the territory and strengthening it - with the assurance of budgetary resources.

  19. A Proposal for a UK Ethics Council for Animal Policy: The Case for Putting Ethics Back into Policy Making.

    2018-06-07

    Substantial controversy is a consistent feature of UK animal health and welfare policy. BSE, foot and mouth disease, bovine TB and badger culling, large indoor dairies, and wild animals in circuses are examples. Such policy issues are inherently normative; they include a substantial moral dimension. This paper reviews UK animal welfare advisory bodies such as the Animal Health and Welfare Board of England, the Farm Animal Welfare Council and the Animals in Science Committee. These bodies play a key advisory role, but do not have adequate expertise in ethics to inform the moral dimension of policy. We propose an "Ethics Council for Animal Policy" to inform the UK government on policy that significantly impacts sentient species. We review existing Councils (e.g., the Nuffield Council on Bioethics and The Netherlands Council on Animal Affairs) and examine some widely used ethical frameworks (e.g., Banner's principles and the ethical matrix). The Ethics Council for Animal Policy should be independent from government and members should have substantial expertise in ethics and related disciplines. A pluralistic six-stage ethical framework is proposed: (i) Problematisation of the policy issue, (ii) utilitarian analysis, (iii) animal rights analysis, (iv) virtue-based analysis, (v) animal welfare ethic analysis, and (vi) integrated ethical analysis. The paper concludes that an Ethics Council for Animal Policy is necessary for just and democratic policy making in all societies that use sentient nonhuman species.

    Chronic disease is by far the leading cause of death worldwide and of increasing concern in low- and middle-income countries, including South Africa, where chronic diseases disproportionately affect the poor living in urban settings. The Provincial Government of the Western Cape (PGWC) has prioritized the management of chronic diseases and has developed a policy and framework (Adult Chronic Disease Management Policy 2009) to guide and improve the prevention and management of chronic diseases at a primary care level. The aim of this study is to assess the alignment of current primary care practices with the PGWC Adult Chronic Disease Management policy. One comprehensive primary care facility in a Cape Town health district was used as a case study. Data was collected via semi-structured interviews (n = 10), focus groups (n = 8) and document review. Participants in this study included clinical staff involved in chronic disease management at the facility and at a provincial level. Data previously collected using the Integrated Audit Tool for Chronic Disease Management (part of the PGWC Adult Chronic Disease Management policy) formed the basis of the guide questions used in focus groups and interviews. The results of this research indicate a significant gap between policy and its implementation to improve and support chronic disease management at this primary care facility. A major factor seems to be poor policy knowledge by clinicians, which contributes to an individual rather than a team approach in the management of chronic disease patients. Poor interaction between facility- and community-based services also emerged. A number of factors were identified that seemed to contribute to poor policy implementation, the majority of which were staff related and ultimately resulted in a decrease in the quality of patient care. Chronic disease policy implementation needs to be improved in order to support chronic disease management at this facility. It is possible that similar

    Many reform efforts in health systems fall short because the use of research evidence to inform policy remains scarce. In Lebanon, one in four adults suffers from a mental illness, yet access to mental healthcare services in primary healthcare (PHC) settings is limited. Using an "integrated" knowledge framework to link research to action, this study examines the process of influencing the mental health agenda in Lebanon through the application of Knowledge Translation (KT) tools and the use of a KT Platform (KTP) as an intermediary between researchers and policymakers. This study employed the following KT tools: 1) development of a policy brief to address the lack of access to mental health services in PHC centres, 2) semi-structured interviews with 10 policymakers and key informants, 3) convening of a national policy dialogue, 4) evaluation of the policy brief and dialogue, and 5) a post-dialogue survey. Findings from the key informant interviews and a comprehensive synthesis of evidence were used to develop a policy brief which defined the problem and presented three elements of a policy approach to address it. This policy brief was circulated to 24 participants prior to the dialogue to inform the discussion. The policy dialogue validated the evidence synthesized in the brief, whereby integrating mental health into PHC services was the element most supported by evidence as well as participants. The post-dialogue survey showed that, in the following 6 months, several implementation steps were taken by stakeholders, including establishing national taskforce, training PHC staff, and updating the national essential drug list to include psychiatric medications. Relationships among policymakers, researchers, and stakeholders were strengthened as they conducted their own workshops and meetings after the dialogue to further discuss implementation, and their awareness about and demand for KT tools increased. This case study showed that the use of KT tools in Lebanon to

    Using symbolic dynamics and information theory, we study the information transmission needed for synchronizing unidirectionally coupled oscillators. It is found that when sustaining chaos synchronization with nongenerating partition, the synchronization error will be larger than a critical value, although the required coupled channel capacity can be smaller than the case of using a generating partition. Then we show that no matter whether a generating or nongenerating partition is in use, a high-quality detector can guarantee the lead of the response oscillator, while the lag responding can make up the low precision of the detector. A practicable synchronization scheme basing on a nongenerating partition is also proposed in this paper.

    Full Text Available During the past decades, national governments and international institutions have both searched for ways to equalise disparities and revitalise lagging regions. Although ideas and examples of the most effective ways to achieve these goals originate in various places, their influence is inclined to permeate elsewhere. Therefore, the processes involved in policy transfers are highly relevant from the perspective of regional development. This study approaches these processes through the case study of post-war Hokkaido and pays special attention to the role of three international development strategies: the Tennessee Valley Authority model, the Growth Pole Theory and the Industrial Cluster Theory. As a result, this research shows the wide variety of agents involved in policy transfer, analyses the processes of incorporating exogenous ideas into regional development polices and demonstrates the variety of sources from which different agents can draw lessons.

    The suprachiasmatic nucleus is a network of synchronized neurons whose electrical activity follows a 24 h cycle. The synchronization phenomenon (among these neurons) is not completely understood. In this work we study, via experiments and numerical simulations, the phenomenon in which the synchronization threshold changes under the influence of an external (bifurcation) parameter in coupled Hindmarsh-Rose neurons. This parameter ;shapes; the activity of the individual neurons the same way as some neurons in the brain react to light. We corroborate this experimental finding with numerical simulations by quantifying the amount of synchronization using Pearson's correlation coefficient. In order to address the local stability problem of the synchronous state, Floquet theory is applied in the case where the dynamic systems show continuous periodic solutions. These results show how the sufficient coupling strength for synchronization between these neurons is affected by an external cue (e.g. light).

    2010-06-01

    Childhood obesity is a serious public health problem resulting from energy imbalance (when the intake of energy is greater than the amount of energy expended through physical activity). Numerous health authorities have identified policy interventions as promising strategies for creating population-wide improvements in physical activity. This case study focuses on energy expenditure through physical activity (with a particular emphasis on school-based physical education [PE]). Policy-relevant evidence for promoting physical activity in youth may take numerous forms, including epidemiologic data and other supporting evidence (e.g., qualitative data). The implementation and evaluation of school PE interventions leads to a set of lessons related to epidemiology and evidence-based policy. These include the need to: (i) enhance the focus on external validity, (ii) develop more policy-relevant evidence on the basis of "natural experiments," (iii) understand that policy making is political, (iv) better articulate the factors that influence policy dissemination, (v) understand the real-world constraints when implementing policy in school environments, and (vi) build transdisciplinary teams for policy progress. The issues described in this case study provide leverage points for practitioners, policy makers, and researchers as they seek to translate epidemiology to policy. Copyright 2010 Elsevier Inc.

    Full Text Available Abstract Introduction Achieving health equity is a pertinent need of the developing health systems. Though policy process is crucial for planning and attaining health equity, the existing evidences on policy processes are scanty in this regard. This article explores the magnitude, determinants, challenges and prospects of 'health equity approach' in various health policy processes in the Indian State of Orissa - a setting comparable with many other developing health systems. Methods A case-study involving 'Walt-Gilson Policy Triangle' employed key-informant interviews and documentary reviews. Key informants (n = 34 were selected from the departments of Health and Family Welfare, Rural Development, and Women and Child Welfare, and civil societies. The documentary reviews involved various published and unpublished reports, policy pronouncements and articles on health equity in Orissa and similar settings. Results The 'health policy agenda' of Orissa was centered on 'health equity' envisaging affordable and equitable healthcare to all, integrated with public health interventions. However, the subsequent stages of policy process such as 'development, implementation and evaluation' experienced leakage in the equity approach. The impediment for a comprehensive approach towards health equity was the nexus among the national and state health priorities; role, agenda and capacity of actors involved; and existing constraints of the healthcare delivery system. Conclusion The health equity approach of policy processes was incomprehensive, often inadequately coordinated, and largely ignored the right blend of socio-medical determinants. A multi-sectoral, unified and integrated approach is required with technical, financial and managerial resources from different actors for a comprehensive 'health equity approach'. If carefully geared, the ongoing health sector reforms centered on sector-wide approaches, decentralization, communitization and involvement of

    2016-01-01

    Full Text Available The paper addresses the issue of EU enlargement with its dual nature: of an intra-EU process, related to the consolidation of a democratic-peace based on collective security, and an external process, involving EU foreign policy and impact on relations with other major global players. Although enlargement is a multidimensional process that combines different perspectives - candidate countries' enlargement politics, member states' politics/policy, EU enlargement politics and external global impact - the paper focuses on Member States policies towards enlargement by looking at the case of Portugal, in particular in relation with the Big Bang Eastern enlargement, and aims at explaining the paradox of Portugal's strong political support to enlargement while it was one of the main potential losers in terms of economic interests. A 'foreign policy analysis' framework is adopted in order to understand the process of decision-making and the interaction between the domestic and the EU levels. The argument put forward is that an exclusive constructivist approach does not provide a satisfactory explanation, as there was also rationalist-interest logic at play. The Portuguese policy towards enlargement was determined not only by the 'solidaritysimilarity' logic, dominant in the formal political discourse but also by the consideration of long-term interests in the EU related to the preservation of the strategic alliance with Germany. The overall systemic impact of enlargement tends to weaken the EU as it presents a major paradox functioning as a double-edged sword. While it has a positive impact by contributing to the enhancement of the EU international profile as it grows in size raising expectations about its potential global role, it also leads to greater heterogeneity, undermining the EU cohesion and its ability to act together with a single voice becoming a robust global player, thus frustrating the expectations raised in the first place.

    Growing demand for transport biofuels in the EU is driving an expansion of the industry in developing countries. Large-scale production of energy crops for biofuel, if mismanaged, could cause detrimental environmental and social impacts. The aim of this study is to examine whether the newly adopted EU Directive 2009/28/EC and its sustainability certification system can effectively ensure sustainable production of biofuels outside the EU. Mozambique, a least developed country with biofuels ambitions, is selected as empirical case. The effectiveness of the EU policy in analysed employing ideal models of external governance (hierarchical, market and network governance) as analytical framework. The findings show that the EU attempts to impose its rules and values on sustainable biofuels using its leverage through trade. The market approach adopted by the EU is expected to produce only unstable (subject to abrupt changes of market prices and demand) and thin (limited to climate and biodiversity issues) policy results. Stronger emphasis on a network oriented approach based on substantial involvement of foreign actors, and on international policy legitimacy is suggested as a way forward. - Research highlights: →The EU attempts to impose its rules and values on sustainable biofuels using its leverage through trade. →The market approach adopted by the EU is expected to produce only unstable (subject to abrupt changes of market prices and demand) and thin (limited to climate and biodiversity issues) policy results.→In order to promote simultaneously stable and substantial impacts, the EU governance approach based on market access should be integrated with a network mode of governance based on policy legitimacy.

    INTRODUCCIÓN: As part of the work carried out within the EURopean micronutrient RECommendations Aligned (EURRECA) Network of Excellence in Spain, we conducted a series of semi-structured interviews with decision makers and relevant scientific institutions in the field of nutrition and public health. The information gathered was collated with national relevant official and unofficial documents and subsequently analysed. To describe the current situation about nutrition policy in Spain, with special focus on the process of setting micronutrient recommendations and the development of subsequent policies. 3 cases will be detailed: iodine, folic acid and vitamin D. Information from 9 interviews was contrasted with the available official and unofficial documents on micronutrients recommendations setting and subsequent policy applications to help the population to achieve their requirements. Common topics and themes were identified in the interviews and desk research. They describe a heterogenic picture of isolated initiatives and timid measures regarding micronutrients recommendations and subsequent policy instruments. Several recommendations coexist but none of them is the result of an official request by the government or competent authority. Iodine, folic acid and vitamin D represent the past, the present and the future of public health policy measures on micronutrients in Spain. Despite of some examples, there exist a need for action. Current nutrition strategies are focused on obesity, with little room for micronutrients national measures despite of the opinion of many experts. Regardless of the several nutrients recommendations coexisting nowadays in Spain, there exist the need for a coordinated action in the field of micronutrients recommendations, fostered by the health and nutrition official authorities with financial support and clear terms of reference.

    To those working on climate change it is obvious that energy policy should be influenced by climate change considerations. The question that this paper seeks to answer is, to what extent do they influence policy and what contribution can a careful analysis of the costs and benefits of climate change options have on the formulation of that policy. We seek to understand this by looking in some detail at energy policy formulation in Russia. To do so it is necessary to look at the whole set of issues that determine energy policy. These include energy security, macroeconomic and uncertainty factors, local environmental issues and social issues. The analysis has been carried out for a specific case - that of the RF, where energy policy is currently under formulation to 2010. Two options have been looked at: a 'High Coal' option, where there would be a substantial change in fuel mix away from gas to coal; and a 'High Gas' option where the current fuel mix is retained and the increase in demand is met from all sources in proportion to current use. The analysis shows that, at international prices for fuels, the 'High Coal' option is attractive. However, when we include the potential decline of price for natural gas in the European market, the relative preference for this option drops dramatically but it still remains the preferred option. When, account is also taken of the carbon benefits of the High Gas option, using plausible values for carbon, the attraction of the High Coal option is further reduced but not altered. When finally account is taken of the health associated with the lower use of coal in the High Gas option, the preference can be reversed but it requires a critical value for the health benefits. This critical value - at around USD 3,000 for a life year lost - is plausible for the RF, if anything the actual value is probably higher. What the analysis shows is the need for a careful evaluation of the different factors determining energy policy. Among these is

    Full Text Available Abstract Background Recommendations from the World Health Organization (WHO are crucial to inform developing country decisions to use, or not, a new intervention. This article analysed the WHO policy development process to predict its course for a malaria vaccine. Methods The decision-making processes for one malaria intervention and four vaccines were classified through (1 consultations with staff and expert advisors to WHO's Global Malaria Programme (GMP and Immunization, Vaccines and Biologicals Department (IVB; (2 analysis of the procedures and recommendations of the major policy-making bodies of these groups; (3 interviews with staff of partnerships working toward new vaccine availability; and (4 review and analyses of evidence informing key policy decisions. Case description WHO policy formulation related to use of intermittent preventive treatment in infancy (IPTi and the following vaccine interventions: Haemophilus influenzae type b conjugate vaccine (Hib, pneumococcal conjugate vaccine (PCV, rotavirus vaccine (RV, and human papillomavirus vaccine (HPV, five interventions which had relatively recently been through systematic WHO policy development processes as currently constituted, was analysed. Required information was categorized in three areas defined by a recent WHO publication on development of guidelines: safety and efficacy in relevant populations, implications for costs and population health, and localization of data to specific epidemiological situations. Discussion and evaluation Data needs for a malaria vaccine include safety; the demonstration of efficacy in a range of epidemiological settings in the context of other malaria prevention interventions; and information on potential rebound in which disease increases subsequent to the intervention. In addition, a malaria vaccine would require attention to additional factors, such as costs and cost-effectiveness, supply and demand, impact of use on other interventions, and

    Full Text Available Historically, cash dividends are the most important form of payout policy; however, they have been losing popularity relative to share repurchases. This paper examines the signaling effect of the payout decisions namely, cash dividends and share repurchases by BSE 500 index companies. It attempts to uncover the underlying forces behind the firm’s choices of payout policy in the Indian context. Using the standard ‘Event Standard Methodology’, a strong case of positive signaling is reported in case of repurchase announcements vis-a-vis cash dividend announcements. It is observed that cash dividends are not perceived by investors as positive signals as they prefer their earnings to be retained by the companies for growth prospects. In case of share repurchases, the existence of undervaluation, signaling and wealth transfer hypotheses is reported, consistent with the fact the share repurchases are welcomed by the Indian companies. The results would provide insights into the economics of the choice between cash dividends versus share repurchases as payout mechanism adopted by the sample companies. The findings would also be useful to the academia as well as industry in understanding the payout practice and the extent to which the Indian managers use the assumptions, models and decision rules regarding payout.

    Synchronous colonic tumours of dual pathology are extremely rare. A review of the literature revealed that few cases have been reported to date. Because of their rarity and lack of specific symptoms, preoperative diagnosis is not easy and there is no protocol as yet for the ideal management of these cases. We present such a case which was treated by a combination of surgery and chemotherapy.

    Evidence-informed decisions can strengthen health systems, improve health, and reduce health inequities. Despite the Beijing, Montreux, and Bamako calls for action, literature shows that research evidence is underemployed in policymaking, especially in the East Mediterranean region (EMR). Selecting the draft nursing practice law as a case study, this policy analysis exercise aims at generating in-depth insights on the public policymaking process, identifying the factors that influence policymaking and assessing to what extent evidence is used in this process. This study utilized a qualitative research design using a case study approach and was conducted in two phases: data collection and analysis, and validation. In the first phase, data was collected through key informant interviews that covered 17 stakeholders. In the second phase, a panel discussion was organized to validate the findings, identify any gaps, and gain insights and feedback of the panelists. Thematic analysis was conducted and guided by the Walt & Gilson's "Policy Triangle Framework" as themes were categorized into content, actors, process, and context. Findings shed light on the complex nature of health policymaking and the unstructured approach of decision making. This study uncovered the barriers that hindered the progress of the draft nursing law and the main barriers against the use of evidence in policymaking. Findings also uncovered the risk involved in the use of international recommendations without the involvement of stakeholders and without accounting for contextual factors and implementation barriers. Findings were interpreted within the context of the Lebanese political environment and the power play between stakeholders, taking into account equity considerations. This policy analysis exercise presents findings that are helpful for policymakers and all other stakeholders and can feed into revising the draft nursing law to reach an effective alternative that is feasible in Lebanon.

    A 75-year-old woman noticed a small mass in the right side breast and consulted our hospital. The results of the detailed examination indicated the synchronous double primary right breast cancer and the same side lung cancer (rS5). One-stage operation from the same skin incision was scheduled. Volume rendering (VR) of computed tomography (CT)-scan was very useful in deciding the position and the length of the skin incision. The breast tumor resection and the right middle lobe resection were successfully performed through 6.5 cm skin incision.

    In the present Letter we show that the concept of the generalized synchronization regime in discrete maps needs refining in the same way as it has been done for the flow systems Koronovskii et al. [Koronovskii AA, Moskalenko OI, Hramov AE. Nearest neighbors, phase tubes, and generalized synchronization. Phys Rev E 2011;84:037201]. We have shown that, in the general case, when the relationship between state vectors of the interacting chaotic maps are considered, the prehistory must be taken into account. We extend the phase tube approach to the systems with a discrete time coupled both unidirectionally and mutually and analyze the essence of the generalized synchronization by means of this technique. Obtained results show that the division of the generalized synchronization into the weak and the strong ones also must be reconsidered. Unidirectionally coupled logistic maps and Hénon maps coupled mutually are used as sample systems.

    Scotland is the first country in the world to pass legislation introducing a minimum unit price (MUP) for alcohol in an attempt to reduce consumption and associated harms by increasing the price of the cheapest alcohol. We investigated the competing ways in which policy stakeholders presented the debate. We then established whether a change in framing helped explain the policy's emergence. We conducted a detailed policy case study through analysis of evidence submitted to the Scottish parliament, and in-depth, one-to-one interviews (n = 36) with politicians, civil servants, advocates, researchers, and industry representatives. Public- and voluntary-sector stakeholders tended to support MUP, while industry representatives were more divided. Two markedly different ways of presenting alcohol as a policy problem were evident. Critics of MUP (all of whom were related to industry) emphasized social disorder issues, particularly among young people, and hence argued for targeted approaches. In contrast, advocates for MUP (with the exception of those in industry) focused on alcohol as a health issue arising from overconsumption at a population level, thus suggesting that population-based interventions were necessary. Industry stakeholders favoring MUP adopted a hybrid framing, maintaining several aspects of the critical framing. Our interview data showed that public health advocates worked hard to redefine the policy issue by deliberately presenting a consistent alternative framing. Framing alcohol policy as a broad, multisectoral, public health issue that requires a whole-population approach has been crucial to enabling policymakers to seriously consider MUP, and public health advocates intentionally presented alcohol policy in this way. This reframing helped prioritize public health considerations in the policy debate and represents a deliberate strategy for consideration by those advocating for policy change around the world and in other public health areas. © 2014

    2010-11-01

    Packet technologies were designed to work in asynchronous mode, where the oscillators in the equipment are free running. Although this allows the underlying infrastructure to operate, many applications exist that require frequency synchronization. Also, the ability to distribute synchronization from center to edge of network declines as infrastructure evolves toward a packet-based architecture. Synchronous Ethernet (SyncE) is a key development of the evolution of Ethernet into a carrier grade technology suitable for the WAN environment where frequency synchronization is required. The time of the day distribution in synchronized network at the physical layer enables many useful propositions in packet handling policies and other network management aspects.

    2016-01-01

    Energy has become the main driver for development as industries grow, agricultural sectors become more modernized, economies boom and countries become wealthy. There are still vast majority of people living under the poverty line especially in the ECOWAS region. The purpose of this study is to explore how improvements in energy access can be a key driver in economic development and progress in the ECOWAS region. Data for the study was obtained from the database of the World Bank. A regression analysis was carried out to establish the relationships between energy access and development indicators. The paper suggests the need for policy makers in the ECOWAS region to focus on targets, such as household access, consumption of electricity, and ease of use instead on supply targets that focus merely on physical coverage. A case on how Ghana is improving energy access is presented. - Highlights: • Energy policies in the ECOWAS region must focus on demand side targets. • Energy policies should target rural and peri-urban areas of the ECOWAS region. • Improved energy access requires a new supply chain energy model.

  10. Policy objective of generic medicines from the investment perspective: The case of clopidogrel.

    The objective of generic drug policies in most countries is defined from a disinvestment perspective: reduction in expenditures without compromising health outcomes. However, in countries with restricted access of patients to original patented drugs, the objective of generic drug policies can also be defined from an investment perspective: health gain by improved patient access without need for additional health budget. This study examines the investment aspect of generic medicines by analyzing clopidogrel utilization in European countries between 2004 and 2014 using multilevel panel data models. We find that clopidogrel consumption was strongly affected by affordability constraints before the generic entry around 2009, but this effect decayed by 2014. After controlling for other variables, utilization had a substantially larger trend increase in lower-income European countries than in the higher-income ones. Generic entry increased clopidogrel consumption only in lower- and average-income countries but not in the highest-income ones. An earlier generic entry was associated with a larger effect. The case of clopidogrel indicates that the entrance of generics may increase patient access to effective medicines, most notably in lower-income countries, thereby reducing inequalities between European patients. Policymakers should also consider this investment aspect of generic medicines when designing pharmaceutical policies. Copyright © 2017 Elsevier B.V. All rights reserved.

  11. Using Health Conditions for Laughs and Health Policy Support: The Case of Food Allergies.

    Abo, Melissa M; Slater, Michael D; Jain, Parul

    Health conditions are sometimes included in entertainment media comedies as a context for and as a source of humor. Food allergies are a typical case in point: They are potentially life-threatening yet may be used in humorous contexts. We conducted a content analysis of food allergies in entertainment media and tested the effects of humorous portrayals from an exemplar entertainment program. The content analysis confirmed that when food allergies were portrayed in television and the movies, it was most frequently in a humorous context and often contained inaccurate information. A follow-up experiment showed viewing a humorous portrayal of food allergies had an indirect negative effect on related health policy support via decreased perceived seriousness of food allergies. Inclusion of an educational video eliminated this effect on reduced policy support, with cognitive dissonance as a mediator. Findings support the hypothesis that portraying a health condition in a humorous context may reduce perceptions of seriousness and willingness to support public health policies to address risks associated with the condition, supporting and extending prior research findings.

  12. Renewable energy for rural development in Ethiopia: the case for new energy policies and institutional reform

    Energy Technology Data Exchange (ETDEWEB)

    Wolde-Ghiorgis, W. [Addis Ababa Univ., Dept. of Electrical and Computer Engineering, Addis Ababa (Ethiopia)

    2002-09-01

    This article argues the case for introducing new energy policies in Ethiopia that will ensure energy initiatives for rural development meet the desired expectations. A review of the rural energy sector in Ethiopia is presented. Rural communities have for centuries relied solely on traditional biomass energy sources, human and animal power. In addition, sample findings show that the basic stock of traditional biomass energy resources is dwindling fast for two reasons: one, due to rapid population growth; and two, due to the absence of energy substitutes for traditional energy sources. Renewable energy technologies and other modern energy technologies are almost non-existent. In terms of budgetary allocation, rural energy development has not received a fair share of public investment in comparison to education, rural road construction and health. A key policy recommendation made in this article is the need for commitment from concerned authorities to the use of renewables for spurring rural development. This could be done through increasing the budget allocation to rural energy, which is currently negligible. Other policy recommendations include the modification of existing institutional frameworks for rural energy delivery, and the design and implementation of appropriate rural energy initiatives suitable for productive activities and sustainable development.

    Full Text Available The Common Agricultural Policy (CAP is one of the oldest and most controversial common policies and it is financed directly from the European Union budget. Some critics of CAP argue that especially in the context of the challenges brought by the international crisis, this policy represents a “burden” for the European budget. Our research aims to responds those critics by showing that CAP may represent an important tool for addressing the external shocks impact on agricultural sector of EU. In this view, we will highlight the role of CAP in sustaining the European farmer during the crisis generated by the Russian import ban, adopted as a response to the sanctions imposed by EU to the Russian Federation in the context of Ukrainian crisis. Using a quantitative and qualitative analysis we will assess how the CAP has supported the European agricultural sector and also the future measures that could be adopted to create a more flexible response in the case of other external shocks.

  14. THE IMPACT THE COMPETITION POLICY HAS ON THE LIBERALISATION OF INTERANTIONAL TRADE. CASE STUDY: THE CARTEL

    Directory of Open Access Journals (Sweden)

    Full Text Available The liberalization of international trade is the key when we talk about globalization from an economic aspect, because only when there will be a single global market can we talk about abundance as to what economic globalization is concerned. It is a known fact that market economies can work in free competition conditions. Taking into account the present tendencies of international trade, a decisive role is played by competition authorities. The policy in this field and the commercial policies play complementary roles, because in the absence of one of the two policies, we cannot see economic development and growth. In order to benefit from the full advantages of a free trade, companies must respect the laws of competition. In this context, in this paper, we proposed to study the way in which the existence of a cartel on a certain market can cancel the positive effects of international trade. The working hypothesis from which we started in this study was the following: identifying a cartel that functioned on the European market before and after the Uruguay Round, in order to study the negative effects that this anti-competition practice had. The Uruguay negotiation Round has been chosen, because the best results concerning the liberalization of international trade have been achieved in it. The cartel case was not chosen at random; we have searched to find one that was active in a field which got significant customs tax reductions in the Uruguay Round. We have decided to analyze the impact which a cartel had in the field of industrial products. Following our study, we have managed to empirically demonstrate the way in which a cartel can cancel the benefits of international trade liberalization. The analysis of the way in which the Industrial Tubes cartel acted on the EU market, as well as the analysis of the indicators that led to the undisputable conclusion that this cartel case canceled the positive effects which should have been felt on the

Consumers obtain about 50% of the benefits excluding program costs. The deregulation scenario would correspond closely to a case where a reformed Common Agricultural Policy (CAP) is applied across member countries. In the current case where Sweden is a member of the EU, the benefits are reduced mainly due to lower prices of inputs and pork.

    Onifade, Temitope Tunbi

    2016-01-01

    The article employs qualitative methods in contextualizing and conceptualizing the hybrid renewable energy support policy. It claims that hybrid policies may combine distinct mechanisms to drive desirable objectives better than traditional policies. A policy cycle helps to frame the United Kingdom's Contracts for Difference and Capacity Market (CFD & CM) scheme as a case study. The CFD & CM policy emerged to address environmental and energy challenges through the deployment of renewable energy (RE) in a low-carbon economy, employing liberalization: Environmental protection is foremost in this scheme. The policy combines and improves on the elements of feed-in tariff (FIT) and quota obligation (QO), and strives to solve the problems of these traditional policies. It addresses regulatory uncertainty under FIT by employing private law mechanics to guarantee above-loss reward for low carbon generation, and addresses market uncertainty under QO by incentivizing the capacity to supply future low carbon energy based on projected demand, hence creating a predictable and stable market. It also accommodates other important commitments. Overall, the CFD & CM scheme is a hybrid policy that engages the energy market mainly for advancing the end goal of environmental protection. To thrive however, it needs to meet private sector interests substantially. - Highlights: •The hybrid support policy combines traditional support systems. •Hybrid policies may drive objectives better than traditional policies. •The UK's contract for difference and capacity market system is a hybrid policy. •Environmental protection is foremost in the UK's hybrid policy. •To thrive, the UK's hybrid policy should address private sector interests.

    Evidence-informed decision-making is essential to ensure that health programs and services are effective and offer value for money; however, barriers to the use of evidence persist. Emerging systems science approaches and advances in technology are providing new methods and tools to facilitate evidence-based decision-making. Simulation modelling offers a unique tool for synthesising and leveraging existing evidence, data and expert local knowledge to examine, in a robust, low risk and low cost way, the likely impact of alternative policy and service provision scenarios. This case study will evaluate participatory simulation modelling to inform the prevention and management of gestational diabetes mellitus (GDM). The risks associated with GDM are well recognised; however, debate remains regarding diagnostic thresholds and whether screening and treatment to reduce maternal glucose levels reduce the associated risks. A diagnosis of GDM may provide a leverage point for multidisciplinary lifestyle modification interventions. This research will apply and evaluate a simulation modelling approach to understand the complex interrelation of factors that drive GDM rates, test options for screening and interventions, and optimise the use of evidence to inform policy and program decision-making. The study design will use mixed methods to achieve the objectives. Policy, clinical practice and research experts will work collaboratively to develop, test and validate a simulation model of GDM in the Australian Capital Territory (ACT). The model will be applied to support evidence-informed policy dialogues with diverse stakeholders for the management of GDM in the ACT. Qualitative methods will be used to evaluate simulation modelling as an evidence synthesis tool to support evidence-based decision-making. Interviews and analysis of workshop recordings will focus on the participants' engagement in the modelling process; perceived value of the participatory process, perceived

    Full Text Available This paper explores the relationships between selected marketing mix elements in the area of FMCG. It discusses the nature and sometimes negative consequences of the dominating marketing paradigm of today, marketing mix management, and furthermore discusses how modern research into, for example in the case of FMCG Companies, the marketing policies as well as customer relationship tactics shows that another approach to marketing is required. It proposes a conceptual framework in which marketing elements are related to the dimensions of brand equity and brand awareness. It also presents a case study deriving from advertising strategies of FMCG Companies showing that the change in advertising spending is related to changes in market share, changes in product plans and changes in the number of competitors modified by the number of customers, their concentration and the size of the advertising budget.

  20. Quantum synchronization of a driven self-sustained oscillator.

    Walter, Stefan; Nunnenkamp, Andreas; Bruder, Christoph

    2014-03-07

    Synchronization is a universal phenomenon that is important both in fundamental studies and in technical applications. Here we investigate synchronization in the simplest quantum-mechanical scenario possible, i.e., a quantum-mechanical self-sustained oscillator coupled to an external harmonic drive. Using the power spectrum we analyze synchronization in terms of frequency entrainment and frequency locking in close analogy to the classical case. We show that there is a steplike crossover to a synchronized state as a function of the driving strength. In contrast to the classical case, there is a finite threshold value in driving. Quantum noise reduces the synchronized region and leads to a deviation from strict frequency locking.

    In this paper, an analysis for chaos synchronization under nonvanishing perturbations is presented. In particular, we use model-matching approach from nonlinear control theory for output synchronization of identical and nonidentical chaotic systems under nonvanishing perturbations in a master-slave configuration. We show that the proposed approach is indeed suitable to synchronize a class of perturbed slaves with a chaotic master system; that is the synchronization error trajectories remain bounded if the perturbations satisfy some conditions. In order to illustrate this robustness synchronization property, we present two cases of study: (i) for identical systems, a pair of coupled Roessler systems, the first like a master and the other like a perturbed slave, and (ii) for nonidentical systems, a Chua's circuit driving a Roessler/slave system with a perturbed control law, in both cases a quantitative analysis on the perturbation is included.

    The potential of various energy sources and technology options in meeting national economic and social development goals in developing countries is assessed. The resource options that are of interest are the development of indigenous resources. In general, two categories of options can be considered: those which correspond to the accelerated implementation of existing elements of the energy system and those which correspond to the introduction of a new technology, such as solar electricity. The various resource and technology options that must be analyzed with respect to a number of criteria or payoff functions are: total demand and fuel mix; reduction of oil consumption; national social goals; total energy costs; and environmental quality. First, a view is constructed of the energy implications of current national economic development plans. A consistent description of the future energy system of the country, under the assumption of current trends and policies is constructed for certain reference years in the future. The values of the payoff functions selected are then calculated for that reference case. The major resource and technology options are identified and the rates at which they can be implemented are determined. Finally, the impact on the various payoff functions of the implementation of each option is calculated. The basic element of the framework is the Reference Energy System, discussed in Secton 3. The energy policy analysis for Peru is used as a reference case. 11 references, 10 figures, 2 tables.

    Synchronized skating is a relatively new competitive sport and data about injuries in this discipline are lacking. Therefore the purpose of this study was to investigate the frequency and pattern of acute and overuse injuries in synchronized skaters. Before and during the World Synchronized Skating Championship 2004, a questionnaire inquiring about the frequency of injuries in this skating discipline was given to 23 participating teams. A total of 514 women and 14 men senior skaters completed the questionnaires (100 % response). Two hundred and eighteen (42.4 %) female and 6 (42.9 %) male skaters had suffered from acute injuries during their synchronized skating career. As some skaters had suffered from more than one injury, the total number of acute injuries in females was 398 and in males 14. In female skaters 19.8 % of acute injuries were head injuries, 7.1 % trunk, 33.2 % upper, and 39.9 % lower extremity injuries. In male skaters 14.3 % were head injuries, 28.6 % upper, and 57.1 % lower extremity injuries, with no report of trunk injuries. Sixty-nine female and 2 male skaters had low back problems and 112 female and 2 male skaters had one or more overuse syndromes during their skating career. Of 155 overuse injuries in female skaters, 102 (65.8 %) occurred during their figure skating career, while 53 injuries (34.2 %) only occurred when they skated in synchronized skating teams. In male skaters, out of 5 overuse injuries, 4 (80 %) occurred in their figure skating career, while 1 (20 %) occurred during their synchronized skating career. Out of the total of 412 injuries, 338 (82 %) occurred during on-ice practice, while 74 (18 %) happened during off-ice training. Ninety-one (26.9 %) acute injures occurred while practicing individual elements, and 247 (73.1 %) on-ice injuries occurred while practicing different team elements. We conclude that injuries in synchronized skating should be of medical concern due to an increasing number of acute injuries, especially

    Explosive synchronization has recently been reported in a system of adaptively coupled Kuramoto oscillators, without any conditions on the frequency or degree of the nodes. Here, we find that, in fact, the explosive phase coexists with the standard phase of the Kuramoto oscillators. We determine this by extending the mean-field theory of adaptively coupled oscillators with full coupling to the case with partial coupling of a fraction f. This analysis shows that a metastable region exists for all finite values of f > 0, and therefore explosive synchronization is expected for any perturbation of adaptively coupling added to the standard Kuramoto model. We verify this theory with GPU-accelerated simulations on very large networks (N ∼ 10{sup 6}) and find that, in fact, an explosive transition with hysteresis is observed for all finite couplings. By demonstrating that explosive transitions coexist with standard transitions in the limit of f → 0, we show that this behavior is far more likely to occur naturally than was previously believed.

    Through a qualitative comparative case study, this investigation examined the process by which three school districts in Wisconsin, U.S.A., developed a school energy policy and complementary energy education plan. To guide the process, the researchers created an outline of recommended steps for the districts to follow. Although there were variations in the sequence and perceived ease of the steps, the Energy Task Force members involved in the process found the outline to be a supportive guide. Further analysis of the cases involved interviewing members of the Energy Task Forces to identify facilitating and obstructing factors. The study concluded that factors such as level of environmental literacy, along with aspects of the school culture and leadership, interacted to influence the successful drafting of school energy policies and education plans. In addition to introducing an outline of recommended steps that can be used by other school policy development teams interested in promoting energy efficiency, this study adds insights into the analysis of energy policy work within the context of a school setting. - Highlights: • School energy policy and complementary energy education plans can be successfully developed with guidelines for policy team membership. • Teacher agency, including environmental literacy, helps overcome barriers in developing school policy and energy education plans. • Administrative support of energy conservation is a key to the development of school energy policies and complementary energy education plans

    The purpose of this study was to evaluate the clinicopathological characteristics and survival outcomes of women with simultaneous endometrial and ovarian carcinomas having the same histopathologic type. A review of medical records from 1997 to 2015 identified 72 patients with simultaneous carcinomas of the endometrium and ovary with the same histopathologic type. Patients with synchronous primary cancers of endometrium and ovary (SCEOs) were compared with patients with primary endometrial cancer with ovarian metastasis (ECOM). Clinical and pathological data were obtained from the patients' medical records. Clinicopathological variables including categorical data were analyzed by χ(2) or Fisher exact test and continuous data by a Student t test. A Kaplan-Meier survival analysis was performed and compared by using the log-rank test. A univariate and multivariate analysis of 72 patients with SCEO with the same histopathologic type revealed that SCEO is an independent prognostic factor of 10-year overall survival. There were 31 patients in the SCEO group and 41 patients in the ECOM group. With a mean follow-up time of 68.2 months, the 10-year overall survival rates were 61.3% and 36.6% in SCEO and ECOM groups, respectively (P = 0.029). Age, menopausal status, stage of ovarian cancer, performing lymphadenectomy, grade of endometrial tumor, omental metastasis, and residual tumor were found to be significant risk factors for recurrence in the synchronous group. The differentiation between SCEO and ECOM is of great clinical importance while our results showed a better prognosis for patients with SCEO compared with patients with ECOM. More aggressive therapeutic approaches may be considered for patients with SCEO who are older, postmenopausal, and/or have advanced grade of endometrial tumor, omental metastasis, and residual tumor. Lymphadenectomy should be performed in every patient with SCEO.

    2011-07-01

    Full Text Available Objective: Bullying is a serious public health problem that may include verbal or physical injury as well as social isolation or exclusion. As a result, research is needed to establish a database for policies and interventions designed to prevent bullying and its negative effects. This paper presented a case study that contributed to the literature by describing an intervention for bullies that has implications for research, practice and related policies regarding bullying.Methods: An individualized intervention for an identified bully was implemented using the Participatory Culture-Specific Intervention Model (PCSIM; Nastasi, Moore, & Varjas, 2004 with a seventh-grade middle school student. Ecological and culture-specific perspectives were used to develop and implement the intervention that included psychoeducational sessions with the student and consultation with the parent and school personnel. A mixed methods intervention design was used with the following informants: the target student, the mother of the student, a teacher and the school counselor. Qualitative data included semi-structured interviews with the parent, teacher and student, narrative classroom observations and evaluation/feedback forms filled out by the student and interventionist. Quantitative data included the following quantitative surveys (i.e., Child Posttraumatic Stress Reaction Index [CPTS-RI] and the Behavior Assessment Scale for Children, 2nd Edition. Both qualitative and quantitative data were used to evaluate the acceptability, integrity and efficacy of this intervention.Results: The process of intervention design, implementation and evaluation are described through an illustrative case study. Qualitative and quantitative findings indicated a decrease in internalizing, externalizing and bullying behaviors as reported by the teacher and the mother, and a high degree of acceptability and treatment integrity as reported by multiple stakeholders.Conclusion: This case

    Full Text Available A new symplectic chaos synchronization of chaotic systems with uncertain chaotic parameters is studied. The traditional chaos synchronizations are special cases of the symplectic chaos synchronization. A sufficient condition is given for the asymptotical stability of the null solution of error dynamics and a parameter difference. The symplectic chaos synchronization with uncertain chaotic parameters may be applied to the design of secure communication systems. Finally, numerical results are studied for symplectic chaos synchronized from two identical Lorenz-Stenflo systems in three different cases.

    Pedersen, Dennis; Pedersen, Torben Bach

    2004-01-01

    The increasing availability of XML-based data sources, e.g., for publishing data on the WWW, means that more and more applications (data consumers) rely on accessing and using XML data. Typically, the access is achieved by defining views over the XML data, and accessing data through these views....... However, the XML data sources are often independent of the data consumers and may change their schemas without notification, invalidating the XML views defined by the data consumers. This requires the view definitions to be updated to reflect the new structure of the data sources, a process termed view...... synchronization. XPath is the most commonly used language for retrieving parts of XML documents, and is thus an important cornerstone for XML view definitions. This paper presents techniques for discovering schema changes in XML data sources and synchronizing XPath-based views to reflect these schema changes...

  5. LHC synchronization test successful

    CERN Multimedia

    The synchronization of the LHC's clockwise beam transfer system and the rest of CERN's accelerator chain was successfully achieved last weekend. Tests began on Friday 8 August when a single bunch of a few particles was taken down the transfer line from the SPS accelerator to the LHC. After a period of optimization, one bunch was kicked up from the transfer line into the LHC beam pipe and steered about 3 kilometres around the LHC itself on the first attempt. On Saturday, the test was repeated several times to optimize the transfer before the operations group handed the machine back for hardware commissioning to resume on Sunday. The anti-clockwise synchronization systems will be tested over the weekend of 22 August.Picture:http://lhc-injection-test.web.cern.ch/lhc-injection-test/

    Exposure in prenatal life to methylmercury (MeHg) has become the topic of intense debate in the United States after the Environmental Protection Agency (EPA) announced a proposal in 2004 to reverse strict controls on emissions of mercury from coal-fired power plants that had been in effect for the preceding 15 years. This proposal failed to incorporate any consideration of the health impacts on children that would result from increased mercury emissions. We assessed the impact on children's health of industrial mercury emissions and found that between 316,588 and 637,233 babies are born with mercury-related losses of cognitive function ranging from 0.2 to 5.13 points. We calculated that decreased economic productivity resulting from diminished intelligence over a lifetime results in an aggregate economic cost in each annual birth cohort of $8.7 billion annually. $1.3 billion of this cost is attributable to mercury emitted from American coal-fired power plants. Downward shifts in intellectual quotient (IQ) are also associated with 1566 excess cases of mental retardation annually. This number accounts for 3.2% of MR cases in the United States. If the lifetime excess cost of a case of MR is $1,248,648 in 2000 dollars, then the cost of these excess cases of MR is $2.0 billion annually. Preliminary data suggest that more stringent mercury policy options would prevent thousands of cases of MR and billions of dollars over the next 25 years.

  7. Developing government policies for distance education: Lessons learnt from two Sri Lankan case studies

    Education, especially higher education, is considered vital for maintaining national and individual competitiveness in the global knowledge economy. Following the introduction of its "Free Education Policy" as early as 1947, Sri Lanka is now the best performer in basic education in the South Asian region, with a remarkable record in terms of high literacy rates and the achievement of universal primary education. However, access to tertiary education is a bottleneck, due to an acute shortage of university places. In an attempt to address this problem, the government of Sri Lanka has invested heavily in information and communications technologies (ICTs) for distance education. Although this has resulted in some improvement, the authors of this article identify several barriers which are still impeding successful participation for the majority of Sri Lankans wanting to study at tertiary level. These impediments include the lack of infrastructure/resources, low English language proficiency, weak digital literacy, poor quality of materials and insufficient provision of student support. In the hope that future implementations of ICT-enabled education programmes can avoid repeating the mistakes identified by their research in this Sri Lankan case, the authors conclude their paper with a list of suggested policy options.

    2008-01-01

    This paper is a critical assessment of the current balance of efforts towards energy research and development (R and D) and the promotion of low-carbon electricity technologies in the UK. We review the UK's main technological options and their estimated cost ranges in the medium term. We contrast the energy R and D spending with the current and expected future cost of renewable promotion policies and point out the high cost of carbon saving through existing renewable promotion arrangements. We also note that liberalisation of the electricity sector has had significant implications for the landscape of energy R and D in the UK. We argue that there is a need for reappraisal of the soundness and balance of the energy R and D and renewable capacity deployment efforts towards new energy technologies. We suggest that the cost-effectiveness of UK deployment policies needs to be more closely analysed as associated costs are non-trivial and expected to rise. We also make a case for considering increasing the current low level of energy R and D expenditure. Much of energy R and D is a public good and we should consider whether the current organisation of R and D effort is fit for purpose. We argue that it is important to build and maintain the research capability in the UK in order to absorb spillovers of technological progress elsewhere in the world. Against this background, the recent signs that an energy R and D renaissance could be underway are therefore positive and welcome

  9. Enforcing the Right to Family Life in Hong Kong Courts: The Case of Dependant Policy

    Directory of Open Access Journals (Sweden)

    Matthew Chuen Ngai Tang

    2017-08-01

    Full Text Available Despite the Hong Kong courts’ seemingly robust protection of fundamental rights and civil liberties, enforcing family rights remains extremely difficult. While the right to family life is safeguarded by both domestic and international human right instruments, applicants in judicial review cases are usually not able to rely on it to challenge the decisions made by the immigration authority. This paper examines the challenges in enforcing the right to family life in Hong Kong’s Dependant Policy with a particular focus on the Hong Kong Court of Appeal’s recent decision in BI v Director of Immigration. The immigration reservation, entered into by the United Kingdom when ratifying the International Covenant on Civil and Political Rights, has become a justification for a restrictive immigration regime even after the transfer of sovereignty. The Hong Kong courts also repeatedly accord wide discretion to immigration authority. The courts’ reluctance to scrutinize socio-economic policies reveals one of the key weaknesses in enforcing fundamental rights in Hong Kong by the way of judicial review.

    The development of urbanization is accelerating in China, and there are great pressures and opportunities in cities to reduce carbon emissions. An emissions inventory is a basic requirement for analyzing emissions of greenhouse gases (GHGs), their potential reduction and to realize low-carbon development of cities. This study describes a method to establish a GHGs emissions inventory in Chinese cities for 6 emission sources including industrial energy consumption, transportation, household energy consumption, commercial energy consumption, industrial processes and waste. Nanjing city was selected as a representative case to analyze the characteristics of carbon emissions in Chinese cities. The results show that carbon emissions in Nanjing have increased nearly 50% during the last decade. The three largest GHGs contributors were industrial energy consumption, industrial processes and transportation, which contributed 37-44%, 35-40% and 6-10%, respectively, to the total GHGs emissions. Per GDP carbon emissions decreased by 55% from 2002 to 2009, and the per capita and per GDP carbon emissions were comparable or even lower than the world average levels. These results have important policy implications for Chinese cities to control their carbon emissions. - Highlights: → Carbon emissions inventory using bottom-up methodology was firstly reported for a Chinese city. → Emission characteristics of Nanjing city were compared with other international cities. → Low carbon policies for Chinese cities were recommended based on the results of this research.

    2009-03-01

    The method of twin surrogates has been introduced to test for phase synchronization of complex systems in the case of passive experiments. In this paper we derive new analytical expressions for the number of twins depending on the size of the neighborhood, as well as on the length of the trajectory. This allows us to determine the optimal parameters for the generation of twin surrogates. Furthermore, we determine the quality of the twin surrogates with respect to several linear and nonlinear statistics depending on the parameters of the method. In the second part of the paper we perform a hypothesis test for phase synchronization in the case of experimental data from fixational eye movements. These miniature eye movements have been shown to play a central role in neural information processing underlying the perception of static visual scenes. The high number of data sets (21 subjects and 30 trials per person) allows us to compare the generated twin surrogates with the "natural" surrogates that correspond to the different trials. We show that the generated twin surrogates reproduce very well all linear and nonlinear characteristics of the underlying experimental system. The synchronization analysis of fixational eye movements by means of twin surrogates reveals that the synchronization between the left and right eye is significant, indicating that either the centers in the brain stem generating fixational eye movements are closely linked, or, alternatively that there is only one center controlling both eyes.

    Oborn, Eivor; Barrett, Michael; Exworthy, Mark

    2011-01-01

    The development of health policy is recognized as complex; however, there has been little development of the role of agency in this process. Kingdon developed the concept of policy entrepreneur (PE) within his ‘windows’ model. He argued inter-related ‘policy streams' must coincide for important issues to become addressed. The conjoining of these streams may be aided by a policy entrepreneur. We contribute by clarifying the role of the policy entrepreneur and highlighting the translational processes of key actors in creating and aligning policy windows. We analyse the work in London of Professor Sir Ara Darzi as a policy entrepreneur. An important aspect of Darzi's approach was to align a number of important institutional networks to conjoin related problems. Our findings highlight how a policy entrepreneur not only opens policy windows but also yokes together a network to make policy agendas happen. Our contribution reveals the role of clinical leadership in health reform.

    2016-07-01

    Developing countries face different problems than developed countries and the use of the same indicator to evaluate and compare both regions can lead to misleading conclusions. Traditional indicators, such as R&D and patents may not capture the whole dynamic of a system, as they are used to compare systems focusing on its current structure. Many authors have been discussing the processes underlying industry transformation, innovation, and economic growth to access a system performance, i.e. the functions of innovation systems. Therefore, the purpose of this paper is to analyze these functions as indicators to measure the performance of the system in order to identify policy issues. In order to do that, we analyze the case of the aeronautic sectoral system of innovation of a region in Brazil. The functional approach helped us to better capture the dynamic of the system, by not restricting our analysis to the system’s structure. (Author)

    This study analyzes the sustainability of Brazil's National Policy for the Evaluation of Primary Health Care, based on the identification and categorization of representative critical events in the institutionalization process. This was an evaluative study of two analytical units: Federal Management of Primary Health Care and State Health Secretariats, using multiple case studies with data collected through interviews and institutional documents, using the critical incidents technique. Events that were temporally classified as specific to implementation, sustainability, and mixed were categorized analytically as pertaining to memory, adaptation, values, and rules. Federal management and one of the State Health Secretariats showed medium-level sustainability, while the other State Secretariat showed strong sustainability. The results indicate that the events were concurrent and suggest a weighting process, since the adaptation of activities, adequacy, and stabilization of resources displayed a strong influence on the others. Innovations and the development of technical capability are considered the most important results for sustainability.

    2014-06-01

    The value of distinguishing native from nonnative invasive species has recently been questioned. However, this dichotomy is important for understanding whether a species' successful dominance is caused by introductions, changing environmental conditions that facilitate an existing population, or both processes. We highlight the importance of knowing the origin of hard-to-detect invasive microorganisms for scientific research, management, and policy using a case study of recent algal blooms of the stalk-producing diatom Didymosphenia geminata. Nuisance blooms have been reported in rivers worldwide and have been hastily attributed to introductions. However, evidence indicates that blooms are probably not caused by introductions but, rather, by environmental conditions that promote excessive stalk production by this historically rare species. Effective responses to invasive microorganisms depend on knowing whether their proliferation is caused by being nonnative or is the result of changing environmental conditions that promote invasive characteristics of native species.

  19. Unconsented HIV testing in cases of occupational exposure: ethics, law, and policy.

    Postexposure prophylaxis (PEP) has substantially reduced the risk of acquiring human immunodeficiency virus (HIV) after an occupational exposure; nevertheless, exposure to HIV remains a concern for emergency department providers. According to published guidelines, PEP should be taken only when source patients are HIV-positive or have risk factors for HIV. Initiating PEP when source patients are uninfected puts exposed persons at risk from taking toxic drugs with no compensating benefit. Forgoing PEP if the source is infected results in increased risk of acquiring HIV. What should be done if source patients refuse HIV testing? Is it justifiable to test the blood of these patients over their autonomous objection? The authors review current law and policy and perform an ethical analysis to determine if laws permitting unconsented testing in cases of occupational exposure can be ethically justified. © 2012 by the Society for Academic Emergency Medicine.

    Research on child interviewing has burgeoned over the past 25 years as expectations about children's agency, competence, and participation in society have changed. This article identifies recent trends in research, policy, and theory with implications for the practice of interviewing children in cases of contested divorce and for the weight to be given the information children provide. A number of fields of relevant research are identified, including studies of families who have participated in the family law system, studies of child witnesses in the field, experimental studies of the effects of interview techniques on children's memory and suggestibility, and ethnographic methods that elicit children's views of their own experiences. Finally, a set of 10 principles for practice are delineated based on the best available science. Copyright 2010 John Wiley & Sons, Ltd.

    Full Text Available The return on investment can be divided in capital gain and dividend payouts. It is a difficult task for management to allocate a sufficient amount in both segments, especially to prevent from agency problems. The firms pay dividends only when enough amounts have after meeting their requirements and short term needs. The purpose of the present study is to empirically investigate the factors determine the dividend payout decisions in the case of Pakistan’s engineeringsector by using the data of thirty-six firms listed on Karachi Stock Exchange from the period 1996 to 2008. By employing various panel data techniques like fixed and random effects, the results suggest that the previous dividend per share, earnings per share, profitability, cash flow, sales growth, and size of the firm are the most critical factors determining dividend policy in the engineering sector of Pakistan.

  2. One- and two-cluster synchronized dynamics of non-diffusively coupled Tchebycheff map networks

    Schäfer, Mirko; Greiner, Martin

    2012-01-01

    We use the master stability formalism to discuss one- and two-cluster synchronization of coupled Tchebycheff map networks. For diffusively coupled map systems, the one-cluster synchronized dynamics is given by the behaviour of the individual maps, and the coupling only determines the stability of the coherent state. For the case of non-diffusive coupling and for two-cluster synchronization, the synchronized dynamics on networks is different from the behaviour of the single individual map. Depending on the coupling, we study numerically the characteristics of various forms of the resulting synchronized dynamics. The stability properties of the respective one-cluster synchronized states are discussed for arbitrary network structures. For the case of two-cluster synchronization on bipartite networks we also present analytical expressions for fixed points and zig-zag patterns, and explicitly determine the linear stability of these orbits for the special case of ring-networks.

  3. The Roles of Science in Local Resilience Policy Development: A Case Study of Three U.S. Cities

    2015-12-01

    The development and deployment of resilience policies within communities in the United States often respond to the place-based, hazard-specific nature of disasters. Prior to the onset of a disaster, municipal and regional decision makers establish long-term development policies, such as land use planning, infrastructure investment, and economic development policies. Despite the importance of incorporating disaster risk within community decision making, resilience and disaster risk are only one consideration community decision makers weigh when choosing how and whether to establish resilience policy. Using a case study approach, we examine the governance, organizational, management, and policy making processes and the involvement of scientific advice in designing and implementing resilience policy in three U.S. communities: Los Angeles, CA; Norfolk, VA; and Flagstaff, AZ. Disaster mitigation or resilience initiatives were developed and deployed in each community with differing levels and types of scientific engagement. Engagement spanned from providing technical support with traditional risk assessment to direct engagement with community decision makers and design of community resilience outreach. Best practices observed include embedding trusted, independent scientific advisors with strong community credibility within local government agencies, use of interdisciplinary and interdepartmental expert teams with management and technical skillsets, and establishing scientifically-informed disaster and hazard scenarios to enable community outreach. Case study evidence suggest science communication and engagement within and across municipal government agencies and scientifically-informed direct engagement with community stakeholders are effective approaches and roles that disaster risk scientists can fill to support resilience policy development.

  4. Synchronization Between Two Different Switched Chaotic Systems By Switching Control

    Directory of Open Access Journals (Sweden)

    Du Li Ming

    2016-01-01

    Full Text Available This paper is concerned with the synchronization problem of two different switched chaotic systems, considering the general case that the master-slave switched chaotic systems have uncertainties. Two basic problems are considered: one is projective synchronization of switched chaotic systems under arbitrary switching; the other is projective synchronization of switched chaotic systems by design of switching when synchronization cannot achieved by using any subsystems alone. For the two problems, common Lyapunov function method and multiple Lyapunov function method are used respectively, an adaptive control scheme has been presented, some sufficient synchronization conditions are attainted, and the switching signal is designed. Finally, the numerical simulation is provide to show the effectiveness of our method.

  5. Langevin approach to synchronization of hyperchaotic time-delay dynamics

    2008-11-07

    In this paper, we characterize the synchronization phenomenon of hyperchaotic scalar nonlinear delay dynamics in a fully-developed chaos regime. Our results rely on the observation that, in that regime, the stationary statistical properties of a class of hyperchaotic attractors can be reproduced with a linear Langevin equation, defined by replacing the nonlinear delay force by a delta-correlated noise. Therefore, the synchronization phenomenon can be analytically characterized by a set of coupled Langevin equations. We apply this formalism to study anticipated synchronization dynamics subject to external noise fluctuations as well as for characterizing the effects of parameter mismatch in a hyperchaotic communication scheme. The same procedure is applied to second-order differential delay equations associated with synchronization in electro-optical devices. In all cases, the departure with respect to perfect synchronization is measured through a similarity function. Numerical simulations in discrete maps associated with the hyperchaotic dynamics support the formalism.

  6. Generalized synchronization and coherent structures in spatially extended systems

    International Nuclear Information System (INIS)

    2014-01-01

    We study the synchronization of a coupled pair of one-dimensional Kuramoto–Sivashinsky systems, with equations augmented by a third-space-derivative term. With two different values of a system parameter, the two systems synchronize in the generalized sense. The phenomenon persists even in the extreme case when one of the equations is missing the extra term. Master–slave synchronization error is small, so the generalized synchronization relationship is useful for predicting the state of the master from that of the slave, or conversely, for controlling the slave. The spatial density of coupling points required to bring about generalized synchronization appears to be related to the wavelength of traveling wave solutions, and more generally to the width of coherent structures in the separate systems

  7. The precautionary principle as a provisional instrument in environmental policy: The Montreal Protocol case study

    based. Many of these scientists act both as “honest brokers” and “issue advocates”, and through their shared interest in policy, may act to narrow the range of policy options. For example, modelled projections of low certainty are reported by Montreal Protocol contributing organisations to promote the importance of adhering to the Montreal Protocol. More comprehensive models of atmospheric chemistry incorporate more factors with interdependencies between variables. Consequently, outcomes projecting high risk and greater uncertainty are projected. As new reports of uncertain risk are propagated by studies from contributing organisations, continued application of the Precautionary Principle is required. The Montreal Protocol case suggests that when environmental studies introduce new concerns that trigger a policy response, the Precautionary Principle will act to perpetuate the research activity of contributing organisations, and extend the implementation of precautionary measures. Given the self-renewing nature this process, the precautionary measures are then not provisional

    Highlights: • A multicriteria technique for assessing energy policy elements has been proposed. • Energy policy elements have been examined based on assigned criteria. • This assessment gives results which are representative of all stakeholders. • Policy elements which are chosen by this method promote sustainability. - Abstract: The adverse environmental consequences and diminishing trend of fossil fuel reserves indicate a serious need for vibrant and judicious energy policy. Energy policy involves a number of stakeholders, and needs to incorporate the interests and requirements of all the key stakeholder groups. This paper presents a methodological technique to assist with formulating, evaluating, and promoting the energy policy of a country in a transparent and representative way with clear scientific justifications and balanced assessments. The multicriteria decision analysis approach has been a widely used technique for evaluating different alternatives based on the interests of a multitude of stakeholders, and goals. This paper utilizes the SMAA (Stochastic Multicriteria Acceptability Analysis) tool, which can evaluate different alternatives by incorporating multiple criteria, in order to examine the preferences of different policy elements. We further extend this technique by incorporating the LEAP model (Long-range Energy Alternatives Planning system) to assess the emission impacts of different policy elements. We demonstrate the application of this evaluation technique by an analysis of four hypothetical policy elements namely Business-as usual (BAU), Renewables (REN), Renewable-biomass only (REN-b), and Energy conservation and efficient technologies (ECET). These are applied to the case of sharing fuel sources for power generation for the Bangladesh power sector. We found that the REN-b and REN policy elements were the best and second best alternatives with 41% and 32% acceptability respectively. This technique gives transparent information for

    2016-03-01

    Full Text Available Public policies are problem oriented and solve a public problem. Making decision and policies does not solve problems by itself but they must be executed effectively. As executing policies is a main step of policy making, formulating indicators for implementing policy is necessary. In this article we conducted a content analysis of elites’ opinions to improve implementation of public policies. Therefore, three major factors have been introduced including policy making, environmental policy implementation and organizational structure factors. Sample data were taken from agricultural organizations of Tehran and Qom. For data gathering library research, interview and questionnaire were used. To analyze the data, k-s, Pearson’s correlation coefficient, confirmatory factors analysis and means comparisons were applied using SPSS and LISREL. Results show all of proposed indicators and measures are valid for implementation of public policies and about important of indicators between two participant groups, indicators in Tehran groups is more important.

  11. Files synchronization from a large number of insertions and deletions

    Synchronization between different versions of files is becoming a major issue that most of the applications are facing. To make the applications more efficient a economical algorithm is developed from the previously used algorithm of “File Loading Algorithm”. I am extending this algorithm in three ways: First, dealing with non-binary files, Second backup is generated for uploaded files and lastly each files are synchronized with insertions and deletions. User can reconstruct file from the former file with minimizing the error and also provides interactive communication by eliminating the frequency without any disturbance. The drawback of previous system is overcome by using synchronization, in which multiple copies of each file/record is created and stored in backup database and is efficiently restored in case of any unwanted deletion or loss of data. That is, to introduce a protocol that user B may use to reconstruct file X from file Y with suitably low probability of error. Synchronization algorithms find numerous areas of use, including data storage, file sharing, source code control systems, and cloud applications. For example, cloud storage services such as Drop box synchronize between local copies and cloud backups each time users make changes to local versions. Similarly, synchronization tools are necessary in mobile devices. Specialized synchronization algorithms are used for video and sound editing. Synchronization tools are also capable of performing data duplication.

    We develop a novel inventory method called Dynamic Hybrid Multi-Region Inventory analysis (DHMRI), which integrates the EEMRIOA and Integrated Hybrid LCA and applies time-dependent environmental intervention information for inventory analysis. Consequently, DHMRI is able to quantify the change in the environmental footprint caused by a specific policy while taking structural changes and technological dynamics into consideration. DHMRI is applied to assess the change in the total CO2 emissions associated with the total final demand caused by the climate policy in Taiwan to demonstrate the practicality of this novel method. The evaluation reveals that the implementation of mitigation measures included in the existing climate policy, such as an enhancement in energy efficiency, promotion of renewable energy, and limitation of the growth of energy-intensive industries, will lead to a 28% increase in the total CO2 emissions and that the main driver is the export-oriented electronics industry. Moreover, a major increase in the total emissions is predicted to occur in Southeast Asia and China. The observations from the case study reveal that DHMRI is capable of overcoming the limitations of existing assessment tools at macro-level evaluation of environmental policies.

    Inter-media synchronization methods developed until now have been based on syntactic timestamping of video frames and audio samples. These methods are not fully appropriate for the synchronization of multimedia objects which may have to be accessed individually by their contents, e.g. content-base data retrieval. We propose a content-based multimedia synchronization scheme in which a media stream is viewed as hierarchial composition of smaller objects which are logically structured based on the contents, and the synchronization is achieved by deriving temporal relations among logical units of media object. content-based synchronization offers several advantages such as, elimination of the need for time stamping, freedom from limitations of jitter, synchronization of independently captured media objects in video editing, and compensation for inherent asynchronies in capture times of video and audio.

  16. The economics of gasoline subsidy cost reduction policy: Case study of Indonesia

    Science.gov (United States)

    Akimaya, Muhammad I.

    A gasoline subsidy distorts the gasoline market with the resulting inefficiencies and takes substantial revenues that arguably could be spent elsewhere with a better impact on economic growth. Governments with such subsidies are aware of their cost yet face difficulties in removing the policy because of strong resistance from the public. This thesis discusses in three essays the problem faced by the government in removing the gasoline subsidy and provides an alternative policy in reducing the subsidy cost applied to the case of Indonesia. In the first essay, we examine the decision-making process from the government's perspective that has an objective of generating savings to fund other programs while maintaining political power, and the influence that the general population has over the decision. Despite the immense literature on political power, there has yet to be any research that mathematically models the decision-making process of a government with influences from the general population. Under the benchmark scenario, the equilibrium strategy is to keep the subsidy intact. However, the results are found to be very sensitive to the magnitude of the shift in political power as well as the preferences of both the government and the people. In the second essay, we estimate the cross-price elasticity of regular gasoline with respect to premium gasoline price. The importance of such knowledge is to accurately determine the impact of fuel pricing policy that tends to have different rates of tax or subsidy depending on the grade of gasoline. Using data on the Mexican gasoline market, regular gasoline demand is estimated with an Autoregressive Distributed Lag (ARDL) model. Endogeneity of the price and structural break are also investigated. The cross-price elasticities between regular and premium gasoline is found to be -0.895, which confirms high substitutability among gasoline with different grades. In the third essay, we look at the unique case of Indonesia that

    The UK has long had a strong commitment to neoliberal policy, the risks of which for population health are well researched. Within Europe, Scotland demonstrates especially poor health outcomes, much of which is driven by high levels of deprivation, wide inequalities and the persistent impacts of deindustrialisation. The processes through which neoliberalism has contributed to this poor health record are the subject of significant research interest. Qualitative case study of a post-industrial town in west central Scotland. Primary data were collected using photovoice (11) and oral history (9) interviews, supplemented by qualitative and quantitative secondary source data. For those who fared poorly after the initial introduction of neoliberal policy in the 1970s, subsequent policy decisions have served to deepen and entrench negative impacts on the determinants of health. Neoliberalism has constituted a suite of rapidly and concurrently implemented policies, cross-cutting a variety of domains, which have reached into every part of people's lives. In formerly industrial parts of west central Scotland, policy developments since the 1970s have generated multiple and sustained forms of deprivation. This case study suggests that a turn away from neoliberal policy is required to improve quality of life and health. © The Author 2017.

  18. Constraining fault activity by investigating tectonically-deformed Quaternary palaeoshorelines using a synchronous correlation method: the Capo D'Orlando Fault as a case study (NE Sicily, Italy)

    Science.gov (United States)

    Meschis, Marco; Roberts, Gerald P.; Robertson, Jennifer

    2016-04-01

    Long-term curstal extension rates, accommodated by active normal faults, can be constrained by investigating Late Quaternary vertical movements. Sequences of marine terraces tectonically deformed by active faults mark the interaction between tectonic activity, sea-level changes and active faulting throughout the Quaternary (e.g. Armijo et al., 1996, Giunta et al, 2011, Roberts et al., 2013). Crustal deformation can be calculated over multiple seismic cycles by mapping Quaternary tectonically-deformed palaeoshorelines, both in the hangingwall and footwall of active normal faults (Roberts et al., 2013). Here we use a synchronous correlation method between palaeoshorelines elevations and the ages of sea-level highstands (see Roberts et al., 2013 for further details) which takes advantage of the facts that (i) sea-level highstands are not evenly-spaced in time, yet must correlate with palaeoshorelines that are commonly not evenly-spaced in elevation, and (ii) that older terraces may be destroyed and/or overprinted by younger highstands, so that the next higher or lower paleoshoreline does not necessarily correlate with the next older or younger sea-level highstand. We investigated a flight of Late Quaternary marine terraces deformed by normal faulting as a result of the Capo D'Orlando Fault in NE Sicily (e.g. Giunta et al., 2011). This fault lies within the Calabrian Arc which has experienced damaging seismic events such as the 1908 Messina Straits earthquake ~ Mw 7. Our mapping and previous mapping (Giunta et al. (2011) demonstrate that the elevations of marine terraces inner edges change along the strike the NE - SW oriented normal fault. This confirms active deformation on the Capo D'Orlando Fault, strongly suggesting that it should be added into the Database of Individual Seismogenic Sources (DISS, Basili et al., 2008). Giunta et al. (2011) suggested that uplift rates and hence faults lip-rates vary through time for this examples. We update the ages assigned to

  20. Using apatite to discriminate synchronous ore-associated and barren granitoid rocks: A case study from the Edong metallogenic district, South China

    Duan, Deng-Fei; Jiang, Shao-Yong

    2018-06-01

    In order to find criteria to discriminate the synchronous ore-associated and barren granitoid rocks, we have determined apatite chemistry associated with ore-associated (Cu-Au) and barren granitoid rocks in the Edong district of the Middle and Lower Yangtze River metallogenic belt, South China. Both rock types give zircon U-Pb ages between 135.0 and 138.7 Ma. Apatite has a higher volatile and Li content (Cl: 0.19-0.57 wt%, average 0.35 wt%, SO3: 0.08-0.71 wt%, average 0.32 wt%, Li: 0.49-7.99 ppm, average 3.23 ppm) in ore-associated rocks than those in barren rocks (Cl: 0.09-0.31 wt%, average 0.16 wt%, SO3: 0.06-0.28 wt%, average 0.16 wt%, Li: 0.15-0.89 ppm, average 0.36 ppm). Apatite (La/Yb)N ratios and Eu/Eu* values are relatively high and show wider variation in ore-associated rocks than those in barren rocks. Apatite (La/Sm)N and (Yb/Sm)N show positive correlation in ore-associated rocks but negative in barren rocks. The higher volatile content occurs in ore-associated magma, favoring Cu-Au transportation and deposition. Furthermore, amphibole fractional crystallization in ore-associated magma further enriched the ore elements in the residual melt. Barren rocks may have undergone fluid exsolution before emplacement, which makes it barren in Cl, S and ore elements (Cu, S). These signatures emphases the significance of volatile and magma evolution in mineralization and indicate that analyses of magmatic apatite can serve to distinguish ore-associated from barren intrusions.

  1. Distance learning through synchronous interactive television.

    Hall, Janis L

    2007-01-01

    The advent and popularity of asynchronous online learning has somewhat obscured a standby technology developed over the last two decades. Interactive videoconferencing, sometimes called "interactive television," though not as glamorous and popular a topic at distance-learning conferences, is still alive and well at many institutions. Three or four years ago, many of us were led to believe that interactive television would go the way of the dinosaurs-everything would soon be in an asynchronous format or on individual desktops. There would no longer be any need for elaborately designed classrooms, networks, and operations staff. To date, this prediction has not come true. In fact, synchronous interactive television has experienced significant growth as newer, easier, and cheaper technologies allow institutions to reach more students with less resource investment. Faculty and students, while appreciating the convenience of asynchronous delivery, still express a need for synchronous communication. This article explores the issues involved in synchronous distance education, the current technologies and proposed future developments, and best practices in terms of classroom design, faculty use, and operational issues. It is not a research article but an anecdotal case study based on Washington State University's experiences over the last 20 years in developing and adapting to new synchronous technologies and creating the support and technical infrastructure to best deliver academic courses through this medium.

  2. A case study of the counterpart technical support policy to improve rural health services in Beijing

    Science.gov (United States)

    2012-01-01

    Background There is, globally, an often observed inequality in the health services available in urban and rural areas. One strategy to overcome the inequality is to require urban doctors to spend time in rural hospitals. This approach was adopted by the Beijing Municipality (population of 20.19 million) to improve rural health services, but the approach has never been systematically evaluated. Methods Drawing upon 1.6 million cases from 24 participating hospitals in Beijing (13 urban and 11 rural hospitals) from before and after the implementation of the policy, changes in the rural–urban hospital performance gap were examined. Hospital performance was assessed using changes in six indices over-time: Diagnosis Related Groups quantity, case-mix index (CMI), cost expenditure index (CEI), time expenditure index (TEI), and mortality rates of low- and high-risk diseases. Results Significant reductions in rural–urban gaps were observed in DRGs quantity and mortality rates for both high- and low-risk diseases. These results signify improvements of rural hospitals in terms of medical safety, and capacity to treat emergency cases and more diverse illnesses. No changes in the rural–urban gap in CMI were observed. Post-implementation, cost and time efficiencies worsened for the rural hospitals but improved for urban hospitals, leading to a widening rural–urban gap in hospital efficiency. Conclusions The strategy for reducing urban–rural gaps in health services adopted, by the Beijing Municipality shows some promise. Gains were not consistent, however, across all performance indicators, and further improvements will need to be tried and evaluated. PMID:23272703

    International Nuclear Information System (INIS)

    Lee, Shun-Chung; Shih, Li-Hsing

    2010-01-01

    This study presents a policy benefit evaluation model that integrates cost efficiency curve information on renewable power generation technologies into real options analysis (ROA) methods. The proposed model evaluates quantitatively the policy value provided by developing renewable energy (RE) in the face of uncertain fossil fuel prices and RE policy-related factors. The economic intuition underlying the policy-making process is elucidated, while empirical analysis illustrates the option value embedded in the current development policy in Taiwan for wind power. In addition to revealing the benefits that RE development provides when considering real options, analytical results indicate that ROA is a highly effective means of quantifying how policy planning uncertainty including managerial flexibility influences RE development. In addition to assessing the policy value of current RE development policy, this study also compares policy values in terms of internalized external costs and varying feed-in tariff (FIT). Simulation results demonstrate that the RE development policy with internalized CO 2 emission costs is appropriate policy planning from sustainability point of view. Furthermore, relationship between varying FIT and policy values can be shown quantitatively and appropriate FIT level could be determined accordingly. (author)

Their control law is thus critical for combining at the same time high productivity to reduced energy consummation. As far as possible, the control algorithms must exploit the properties of these actuators. Therefore, this work draws on well adapted models resulting from the Park's transformation, for both the most traditional machines with sinusoidal field distribution and for machines with non-sinusoidal field distribution which are more and more used in

    Given Jung's interest in physics' formulations of psychic energy and the concept of time, overlaps and convergences in the themes addressed in analytical psychology and in quantum physics are to be expected. These are informed by the active intersections between the matter of mind and mindfulness re matter. In 1911, Jung initiated dinners with Einstein. Jung's definition of libido in the pivotal 1912 Fordham Lectures reveals the influence of these conversations. Twenty years later, a significant period in physics, Wolfgang Pauli contacted Jung. Their collaboration led to the theory of synchronicity. © 2014, The Society of Analytical Psychology.

    This paper describes the synchronisation system under development on the Laser Megajoule (LMJ) in order to synchronize the laser quads on the target to better than 40 ps rms. Our architecture is based on a Timing System (TS) which delivers trigger signals with jitter down to 15 ps rms coupled with an ultra precision timing system with 5 ps rms jitter. In addition to TS, a sensor placed at the target chamber center measures the arrival times of the 3 omega nano joule laser pulses generated by front end shots. (authors)

    Preservation of stability in the presence of structural and/or parametric changes is an important issue in the study of dynamical systems. A specific case is the synchronization of chaos in complex networks where synchronization should be preserved in spite of changes in the network parameters and connectivity. In this work, a methodology to establish conditions for preservation of stability in a class of dynamical system is given in terms of Lyapunov methods. The idea is to construct a group of dynamical transformations under which stability is retained along certain manifolds. Some synchronization examples illustrate the results.

    The paper investigates the relevance of participatory approaches to environmental policy-making when sustainable development is taken as the encompassing normative basis for environmental governance. In the first section, we illustrate the frequent references to participatory approaches in environmental decision-making. We then look at environmental issue attributes as determinants of the problem-solving requirements for environmental decision-making. We conclude the section by investigating whether and how participatory approaches could answer some of these requirements. In the second section, an illustration is proposed with the presentation of a participatory process that took place in 1997, during the last phase of the international negotiations that led to the Kyoto Conference of the Parties to the UN Framework Convention on Climate Change, and in 1998 in the preparation of the post-Kyoto phase. The process, organised by the European Commission, consisted of a series of workshops whose objective was to furnish timely inputs responding to the European Commission's information needs for climate policy formation in the pre- and post-Kyoto periods. This was to be achieved through the establishment of interfaces between: (1) the research community; (2) the EC Climate negotiation team and through it the EU Member States representatives; (3) other Commission interests (the 'inside stakeholders'); (4) a range of 'outside' stakeholders including industry, finance and commerce, employment, environment, consumer and citizen interests. We reflect on the participatory nature of the process and show how the process met some of the decision-making requirements identified in the first section. 27 refs

    2015-01-01

    Highlights: • A definition of multi-purpose technologies (MPTs) is proposed. • Opportunities for a cost-efficient demand-pull policy strategy for MPTs are derived. • The multi-purpose character of stationary electricity storage (SES) is shown. • An exemplary profitability assessment of one SES technology supports the argument. - Abstract: Stationary electricity storage technologies (SES) allow to increase the shares of intermittent renewable energy technologies in electricity networks. As SES currently exhibit high costs, policy makers have started introducing demand-pull policies in order to foster their diffusion and drive these technologies further down the learning curve. However, as observed in the case of renewable energy technologies, demand-pull policies for technologies can come at high costs in cases where the profitability gap that needs to be covered by the policy support is large. Yet, SES can create value in multiple distinct applications in the power system – making it a “multi-purpose technology”. We argue that policy makers can make use of the multi-purpose character of SES to limit costs of demand-pull policies. We propose a policy strategy which grants support based on the profitability gap in the different applications, thereby moving down the learning curve efficiently. To support our argumentation, we firstly conduct a comprehensive literature review of SES applications exemplifying the multi-purpose character of these technologies. Second, we assess the profitability of one SES technology (vanadium redox flow battery) in five SES applications, highlighting a strong variation of the profitability gap across these applications

    2012-01-01

    This paper introduces an average contraction analysis for nonlinear switched systems and applies it to investigating the synchronization of complex networks of coupled systems with switching topology. For a general nonlinear system with a time-dependent switching law, a basic convergence result is presented according to average contraction analysis, and a special case where trajectories of a distributed switched system converge to a linear subspace is then investigated. Synchronization is viewed as the special case with all trajectories approaching the synchronization manifold, and is thus studied for complex networks of coupled oscillators with switching topology. It is shown that the synchronization of a complex switched network can be evaluated by the dynamics of an isolated node, the coupling strength and the time average of the smallest eigenvalue associated with the Laplacians of switching topology and the coupling fashion. Finally, numerical simulations illustrate the effectiveness of the proposed methods. (paper)

    Variations in target volume position between and during treatment fractions can lead to measurable differences in the dose distribution delivered to each patient. Current methods to estimate the ongoing cumulative delivered dose distribution make idealized assumptions about individual patient motion based on average motions observed in a population of patients. In the delivery of intensity modulated radiation therapy (IMRT) with a multi-leaf collimator (MLC), errors are introduced in both the implementation and delivery processes. In addition, target motion and MLC motion can lead to dosimetric errors from interplay effects. All of these effects may be of clinical importance. Here we present a method to compute delivered dose distributions for each treatment beam and fraction, which explicitly incorporates synchronized real-time patient motion data and real-time fluence and machine configuration data. This synchronized dynamic dose reconstruction method properly accounts for the two primary classes of errors that arise from delivering IMRT with an MLC: (a) Interplay errors between target volume motion and MLC motion, and (b) Implementation errors, such as dropped segments, dose over/under shoot, faulty leaf motors, tongue-and-groove effect, rounded leaf ends, and communications delays. These reconstructed dose fractions can then be combined to produce high-quality determinations of the dose distribution actually received to date, from which individualized adaptive treatment strategies can be determined

  1. SLAC synchronous condenser

    International Nuclear Information System (INIS)

    Corvin, C.

    1995-06-01

    A synchronous condenser is a synchronous machine that generates reactive power that leads real power by 90 degrees in phase. The leading reactive power generated by the condenser offsets or cancels the normal lagging reactive power consumed by inductive and nonlinear loads at the accelerator complex. The quality of SLAC's utility power is improved with the addition of the condenser. The inertia of the condenser's 35,000 pound rotor damps and smoothes voltage excursions on two 12 kilovolt master substation buses, improving voltage regulation site wide. The condenser absorbs high frequency transients and noise in effect ''scrubbing'' the electric system power at its primary distribution source. In addition, the condenser produces a substantial savings in power costs. Federal and investor owned utilities that supply electric power to SLAC levy a monthly penalty for lagging reactive power delivered to the site. For the 1993 fiscal year this totaled over $285,000 in added costs for the year. By generating leading reactive power on site, thereby reducing total lagging reactive power requirements, a substantial savings in electric utility bills is achieved. Actual savings of $150,000 or more a year are possible depending on experimental operations

  4. Synchronization of Coupled FitzHugh-Nagumo Neurons Using Self-Feedback Time Delay

    Science.gov (United States)

    Fan, Denggui; Song, Xinle; Liao, Fucheng

    Many neurological diseases are characterized by abnormally synchronous oscillations of neuronal populations. However, how the neurons can synchronize with each other is still not fully understood, which may have potentially hampered the understanding and diagnosis for these dynamical diseases. In this paper, the self-feedback time delay (SFTD) and adaptive control theory are employed to control the onset of synchronization in the coupled FitzHugh-Nagumo (FHN) neurons. It is found that the larger SFTD can induce the complete synchronization of coupled neuronal system. Further investigation reveals that the reinforcing SFTD can significantly postpone the synchronization onsets. In addition, for the case that synchronization cannot be achieved by adjusting SFTD, the parameter estimation update laws and adaptive controller with respect to SFTD of coupled system are investigated to deduce the sufficient condition for complete synchronization. Simulations are also provided to illustrate the effectiveness of the proposed methods. In particular, we observed the fascinating dynamical synchronization transitions, such as chaotic synchronization and bursting synchronization transitions, as well as the transition from anti-synchronization to complete synchronization.

    Full Text Available Purpose: the main purpose of this article was to study the modern tools of the public innovation policy in the global pharmaceutical industry (US and EU cases, which is one of the most knowledge-intensive sectors of the global economy. During the study, it was necessary to achieve the following objectives: to identify main components of the innovation policy in the sector, to consider the role of intellectual property protection, measures of innovation support, regulatory control and other factors, and, also, to identify comparative characteristics of innovation processes within the US and the EU pharmaceutical sector. Methods: this article is based on a qualitative comparative study of the US and EU innovation policy in the pharmaceutical industry. Industryoriented innovation support measures (i.e. levels of private and public financing have been quantitatively analyzed, including the evaluation of the levels of R&D productivity; also, a comparative study of the pharma patent statistics in the leading countries have been performed. This article highlights the problems of intellectual property protection, which remains an important source of financial stability for major pharma companies being the basis for new innovation agenda. Low R&D productivity and high costs of new innovative drugs together emphasize the significance of the analysis of current innovation processes within the pharmaceutical industry, and could open the way for building more effective managerial and business processes. Results: the global pharmaceutical industry today is under thorough control of government regulators and civil society organizations seeking to improve mechanisms of the drugs distribution, in order to make drugs more accessible, safe and clean. This high regulation level impedes innovation within existing pharma business models, and leads to high costs of the newest drugs. The study revealed that successful pharmaceutical innovation today requires

    Farrell, Niall; Donoghue, Cathal O’; Morrissey, Karyn

    2015-01-01

    Wave Energy Conversion (WEC) devices are at a pre-commercial stage of development with feasibility studies sensitive to uncertainties surrounding assumed input costs. This may affect decision making. This paper analyses the impact these uncertainties may have on investor, developer and policymaker decisions using an Irish case study. Calibrated to data present in the literature, a probabilistic methodology is shown to be an effective means to carry this out. Value at Risk (VaR) and Conditional Value at Risk (CVaR) metrics are used to quantify the certainty of achieving a given cost or return on investment. We analyse the certainty of financial return provided by the proposed Irish Feed-in Tariff (FiT) policy. The influence of cost reduction through bulk discount is also discussed, with cost reduction targets for developers identified. Uncertainty is found to have a greater impact on the profitability of smaller installations and those subject to lower rates of cost reduction. This paper emphasises that a premium is required to account for cost uncertainty when setting FiT rates. By quantifying uncertainty, a means to specify an efficient premium is presented. - Highlights: • Probabilistic model quantifies uncertainty for wave energy feasibility analyses. • Methodology presented and applied to an Irish case study. • A feed-in tariff premium of 3–4 c/kWh required to account for cost uncertainty. • Sensitivity of uncertainty and cost to rates of technological change analysed. • Use of probabilistic model for investors and developers also demonstrated

    2015-01-01

    Responding to a global trend of installing smart meters Norway has taken a route of full governmental and regulatory coordination. The article maps and analyses the main influences on the developments of Norwegian Advanced Metering policy. Based on 12 interviews and extensive document mapping the Norwegian policy developments are traced from about 1990 to 2014, divided into three phases: Before 2000, between 2000 and 2007, and after 2007. It finds that the main influence and push came from an increasingly united industry sector, fronted by the grid utilities with respective interest organizations. Policy change has been boosted by years of constrained supply, creating incentives for political action. Also developments at the EU level have been important for creating attention for smart meters, while consumer groups have been less influential. The national regulator NVE has adapted its policy process to include external expertise, in particular from the grid companies. The findings confirm that influence into policy processes is a matter of financial and organizational resources and expert knowledge. Of particular policy relevance is the weak organization of private consumer interests into these policy streams, which may be important for further policy development for distributed generation and regulation of private generation activities. -- Highlights: •Roll-out of smart meters is in Norway coordinated by national regulation. •Grid companies and related interest organizations has been most influential. •EU has provided informal pressure on smart meter policy. •Consumer interests have been less influential in the policy process

    2016-11-01

    Full Text Available Drawing on interviews with people from the advertising and technology industry, legal experts and policy makers, this paper assesses the rise of emotion detection in digital out-of-home advertising, a practice that often involves facial coding of emotional expressions in public spaces. Having briefly outlined how bodies contribute to targeting processes and the optimisation of the ads themselves, it progresses to detail industrial perspectives, intentions and attitudes to data ethics. Although the paper explores possibilities of this sector, it pays careful attention to existing practices that claim not to use personal data. Centrally, it argues that scholars and regulators need to pay attention to the principle of intimacy. This is developed to counter weaknesses in privacy that is typically based on identification. Having defined technologies, use cases, industrial perspectives, legal views and arguments about jurisprudence, the paper discusses this ensemble of perspectives in light of a nationwide survey about how UK citizens feel about the potential for emotion detection in out-of-home advertising.

    2010-01-01

    The process of climate change is already under way and is a serious threat facing the planet. Our response to this threat will irrevocably transform the energy sector and the priorities within it. The trend in emissions over the next decade will largely determine whether the process of climate change can be kept at a moderate level. This literature-based study focuses on Finland as an example case. Oil price fluctuations, economic development and changes in consumer values and attitudes are key forces that will drive change in the energy sector. A greater diversity of energy sources is vital if we are to avoid a catastrophic warming of the climate. The use of renewable energy sources must be increased, and the efficiency of producing, transmitting and distributing energy must be improved. The energy sector must also exploit the potential of nuclear energy, wind, solar and hydro power, afforestation measures, biomass resources, carbon capture and storage (CCS) technology and the nano-bio sector. National policies and measures must be set out in detail and global cooperation enhanced. The presence and impact of factors that impede the work to curb climate change must also be taken into account in energy strategies if these strategies are to be successful. (author)

    2016-03-01

    Full Text Available Fluorescent lamps are used increasingly today. Considered energy-saving lamps, they become hazardous waste at the end of their life cycle. They are composed partly of mercury, considered harmful to human health. Fluorescent lamps, together with tires and pesticide containers, fall under federal legislation that establishes and regulates their proper disposal. In 2010, Federal Law 12.305 / 2010 was created, establishing the National Policy on Solid Waste (PNRS, making businesses and consumers responsible for the proper disposal of their waste. This article aims to analyze the reverse logistics process of fluorescent lamps post-consumption, in a public education institution. The research used case studies and interviews with managers of the materials administration and warehouse departments of the institution. It was identified that since 2010, the educational institution has not been performing reverse logistics and has been accumulating hazardous material in its warehouses. This paper contributes a suggestion to improve the reverse logistics process and worker safety, and to prevent environmental risks.

    2017-02-01

    Full Text Available The future of climate and sustainable energy are interrelated. Speaking of one without mentioning the other is quite difficult. The increasing number of natural disasters pose a great threat to the electric power supply security in any part of the world. Sweden has been one of the countries that have suffered from unacceptably long blackouts. The tremendous outcomes of the power interruptions have made the field of the economic worth of electric power reliability a popular area of interest among researchers. Nature has been the number one enemy against the supply security of the electricity. This paper introduces a recent and thorough electric power reliability analysis of Sweden and focuses on the country’s struggle against climate change-related natural disasters via updating the country’s electric power policy to improve its service quality. The paper highlights the Gudrun storm of 2005 as a case study to demonstrate the severe impacts of extreme weather events on the energy systems. The economic damage of the storm on the electric power service calculated to be around 3 billion euros.

    Science.gov (United States)

    Zervos, Vasilis

    2002-01-01

    This paper examines the impact of strategic interactions on Private-Public Partnerships (PPPs) in space. Though there is substantial business and economics literature on PPPs, it is traditionally focused on the relationships within the partnerships (low level) and the respective factors affecting its success. The contribution of this paper is that it examines the political economy of PPPs, analysing how `high-level' strategic interactions across public-private sectors in Europe and the US determine their behaviour and success. Within this context, the European case of Galileo and other national space projects, such as the US plans for a space-based anti- missile defence, are each based on different types of PPPs, confined within the geographical borders of the two areas. The security and commercial benefits of such programmes for the respective space industries and economies have a direct impact on the other area's industry and sense of security. The paper shows that trans- Atlantic cooperation at public policy level is essential to allow the respective industries to explore the benefits of cross-border strategic research partnerships (SRPs). This will reduce the costs of the respective programmes, addressing security concerns.

    2007-01-01

    We identify and explain factors that affected a community's perception of risk due to extensive industrial contamination and people's distrust of government agencies regarding the environmental investigations. Intrinsic bounded case study methodology was used to conduct research about extensive environmental contaminations due to activities of an oil refinery in North Casper, Wyoming, and the citizens' response. Data were collected from multiple sources that included public testimonies, observations, public hearings and meetings minutes, newspaper articles, archived records obtained from federal and state environmental and health agencies, as well as industry records obtained through Freedom of Information Act (FOIA) requests. The overarching theme that emerged was lack of trust due to several critical events and factors such as no response or delay in response time to community concerns, lack of transparency, perceived cover up, vague and fragmented communication by government and state officials, perception of pro-industry stance, and perceived unfair treatment. People's perception of environmental risks and their willingness to accept official explanations and outcomes of environmental investigations are strongly affected by their direct experiences with government agencies and the evidence of influence the powerful industries exert over relevant investigations. The government cannot successfully address public and community concerns about environmental health impacts of contaminations and in turn the public perception of risk unless it adopts and implements policies, procedures, and protocols that are clear, timely, transparent, and free from industry influence.

    2008-12-01

    To analyse the media and political reactions to the initial decision of the Pharmaceutical Benefits Advisory Committee (PBAC) to reject funding of the quadrivalent human papilloma virus (HPV) vaccine in Australia. A case study, informed by media reports and government documents, was utilised to examine the reactions of key stakeholders; PBAC, consumers, consumer organisations, pharmaceutical industry, politicians, health professionals and the media to the initial decision to reject funding of HPV vaccine. The initial decision to reject funding of the HPV vaccine led to unprecedented public response with over 300 newspaper articles and calls by consumers, health professionals and politicians to intervene in the decision making process. Misunderstanding of the decision making process, particularly cost-effectiveness assessments, the need for an independent process, the legislated inability of a timely and transparent response from policy makers and the lack of a risk mitigation strategy all played a role in the public outcry. Despite 15 years of implementation of cost-effectiveness assessments there is still a need for improving stakeholder understanding of the decision making process and for timely transfer of complete information. Risk mitigation strategies should be considered as part of the communication plan for all decisions.

The necessary and sufficient conditions for the synchronization, de-synchronization and instantaneous synchronization (penetration or grazing) are presented. Using such a synchronization theory, the synchronization of a controlled pendulum with the Duffing oscillator is systematically discussed as a sampled problem, and the corresponding analytical conditions for the synchronization are presented. The synchronization parameter study is carried out for a better understanding of synchronization characteristics of the controlled pendulum and the Duffing oscillator. Finally, the partial and full synchronizations of the controlled pendulum with periodic and chaotic motions are presented to illustrate the analytical conditions. The synchronization of the Duffing oscillator and pendulum are investigated in order to show the usefulness and efficiency of the methodology in this paper. The synchronization invariant domain is obtained. The technique presented in this paper should have a wide spectrum of applications in engineering. For example, this technique can be applied to the maneuvering target tracking, and the others.

  20. Biologically Inspired Intercellular Slot Synchronization

    Directory of Open Access Journals (Sweden)

    2009-01-01

    Full Text Available The present article develops a decentralized interbase station slot synchronization algorithm suitable for cellular mobile communication systems. The proposed cellular firefly synchronization (CelFSync algorithm is derived from the theory of pulse-coupled oscillators, common to describe synchronization phenomena in biological systems, such as the spontaneous synchronization of fireflies. In order to maintain synchronization among base stations (BSs, even when there is no direct link between adjacent BSs, some selected user terminals (UTs participate in the network synchronization process. Synchronization emerges by exchanging two distinct synchronization words, one transmitted by BSs and the other by active UTs, without any a priori assumption on the initial timing misalignments of BSs and UTs. In large-scale networks with inter-BS site distances up to a few kilometers, propagation delays severely affect the attainable timing accuracy of CelFSync. We show that by an appropriate combination of CelFSync with the timing advance procedure, which aligns uplink transmission of UTs to arrive simultaneously at the BS, a timing accuracy within a fraction of the inter-BS propagation delay is retained.

    Full Text Available The regional policy is one of the European Union’s main investment policies to support regional equality and convergence, cohesion policy being one of its key policy areas and aiming to support job creation, business competitiveness, economic growth, sustainable development and citizens’ quality of life. As education, research and innovation are amongst the main objectives of these policies, universities play an important role in regional development, research and education being their main tasks, while interaction with society the third one. The aim of this study is to examine how universities participate in cohesion policy and regional development by utilising structural funds in fulfilling their third task (RQ1 and how do the closest stakeholder groups view the regional role of the university (RQ2. A single case study was conducted having the Oulu Southern Institute (OSI of the University of Oulu as the case study unit. The data was collected using an adapted Delphi method in a workshop with OSI staff, from an online questionnaire to OSI’s closest stakeholders and from in-depth interviews to examine the themes that arose in the questionnaire answers. In the findings, the importance of the university unit for regional development is clearly evident. Structural funds are the main tools for universities to stimulate development, the university was seen as a crucial actor, knowledge creator, collaboration partner and regional developer, as well as a fundamental part of the regional innovation system.According to the findings, the university should participate in recommending development areas for cohesion policy guidelines for the next structural fund period.

    Evidence-based policy documents that are well developed by senior civil servants and are timely available can reduce the barriers to evidence utilization by health policy makers. This study examined the barriers and facilitators in developing evidence-based health policy documents from the perspective of their producers in a developing country. In a qualitative study with a framework analysis approach, we conducted semi-structured interviews using purposive and snowball sampling. A qualitative analysis software (MAXQDA-10) was used to apply the codes and manage the data. This study was theory-based and the results were compared to exploratory studies about the factors influencing evidence-based health policy-making. 18 codes and three main themes of behavioral, normative, and control beliefs were identified. Factors that influence the development of evidence-based policy documents were identified by the participants: behavioral beliefs included quality of policy documents, use of resources, knowledge and innovation, being time-consuming and contextualization; normative beliefs included policy authorities, policymakers, policy administrators, and co-workers; and control beliefs included recruitment policy, performance management, empowerment, management stability, physical environment, access to evidence, policy making process, and effect of other factors. Most of the cited barriers to the development of evidence-based policy were related to control beliefs, i.e. barriers at the organizational and health system levels. This study identified the factors that influence the development of evidence-based policy documents based on the components of the theory of planned behavior. But in exploratory studies on evidence utilization by health policymakers, the identified factors were only related to control behaviors. This suggests that the theoretical approach may be preferable to the exploratory approach in identifying the barriers and facilitators of a behavior.

  6. The Kenyan national response to internationally agreed sexual and reproductive health and rights goals: a case study of three policies.

    While priorities for, and decision-making processes on, sexual and reproductive health and rights have been determined and led mainly at the international level, conflicting power dynamics and responses at the national level in some countries have continued to pose challenges for operationalising international agreements. This paper demonstrates how these conflicts have played out in Kenya through an analysis of three policy-making processes, which led to the Adolescent Reproductive Health and Development Policy (2003), the Sexual Offences Act (2006), and the National Reproductive Health Policy (2007). The paper is based on data from a broader study on the drivers and inhibitors of sexual and reproductive health policy reform in Kenya, using a qualitative, case study design. Information was gathered through 54 semi-structured, in-depth interviews with governmental and civil society policy actors and an extensive review of policy documents and media reports. The paper shows that the transformative human rights framing of access to sexual and reproductive health, supported by both a strong global women's rights movement and progressive governmental and inter-governmental actors to defeat opposition to sexual and reproductive health and rights at the international level, has not been as influential or successful at the national level in Kenya, and has made comprehensive national reforms difficult to achieve.

    Full Text Available The paper investigates the extent to which Romania’s largest travel agencies adopt and implement corporate social responsibility (CSR policies, correlating these findings with their business performance reflected by their net turnover and net profit. In order to evaluate the level of CSR policies adoption and implementation, an online survey was conducted among top managers from each travel agency. The questionnaire comprised several sets of items reflecting workplace, environmental, marketplace, community, and, respectively, company values policies. Our results point to the fact that the CSR policies adopted and implemented to the highest degree are those concerning the marketplace, while the least embraced CSR policies refer to the environment. Our findings also suggest that there are several CSR policies which are adopted and implemented to a higher degree by larger travel agencies in terms of net turnover, while some other CSR policies are adopted more thoroughly by smaller ones. The results also indicate positive correlations between the profitability of travel agencies and the adoption and implementation of certain CSR policies. Last but not least, our research suggests that marketplace policies adoption and implementation could have a significant positive impact on business performance of travel agencies in terms of both net turnover and net profitability.

    A political agreement from 2005 stated that an evaluation of the entire Danish energy efficiency policy portfolio must be carried out before the end of 2008, with the aim to assess the following: (1) Is the policy portfolio sufficient to meet the energy efficiency targets? (2) Do the policies enable the national goals to be met in a cost-effective manner? (3) Is the overall design of the policy portfolio appropriate? The evaluation gave recommendations on how to improve and develop the portfolio, mainly using cost-effectiveness as criteria. The evaluation was completed in December 2008, and this paper presents the main findings and the subsequent impact on Danish policy. A key lesson learned is the importance of including all energy efficiency policies in the evaluation. Examining the entire portfolio of policies (as opposed to only selected policies) gave way to findings that would otherwise not have been captured. With its broad perspective, the evaluation found that the policy instruments prioritised the commercial and industrial sectors less than the household and public sectors. The recommendations made by the authors contributed to the implementation of new taxes for the commercial and industrial sectors together with the reform of the Electricity Saving Trust to a Centre for Energy Savings charged with energy savings within all sectors, except transport - both which have been important steps towards a more cost-effective solution.

    2016-03-05

    Evidence-based policy (EBP), a concept modelled on the principles of evidence-based medicine (EBM), is widely used in different areas of policymaking. Systematic reviews (SRs) with meta-analyses gradually became the methods of choice for synthesizing research evidence about interventions and judgements about quality of evidence and strength of recommendations. Critics have argued that the relation between research evidence and service policies is weak, and that the notion of EBP rests on a misunderstanding of policy processes. Having explored EBM standards and knowledge requirements for health policy decision-making, we present an empirical point of departure for discussing the relationship between EBM and EBP. In a case study exploring the Norwegian Knowledge Centre for the Health Services (NOKC), an independent government unit, we first searched for information about the background and development of the NOKC to establish a research context. We then identified, selected and organized official NOKC publications as an empirical sample of typical top-of-the-line knowledge delivery adhering to EBM standards. Finally, we explored conclusions in this type of publication, specifically addressing their potential as policy decision tools. From a total sample of 151 SRs published by the NOKC in the period 2004-2013, a purposive subsample from 2012 (14 publications) advised major caution about their conclusions because of the quality or relevance of the underlying documentation. Although the case study did not include a systematic investigation of uptake and policy consequences, SRs were found to be inappropriate as universal tools for health policy decision-making. The case study demonstrates that EBM is not necessarily suited to knowledge provision for every kind of policy decision-making. Our analysis raises the question of whether the evidence-based movement, represented here by an independent government organization, undertakes too broad a range of commissions using

It argues that, in the case of Poland, the politicization of the domestic administrative structures before 2004 constrained the ability of the state to impact on the EU’s external agenda after the enlargement. It also claims that a rapid adaptation to the EU occurred only after the Polish accession to the EU, as the will to influence the EU’s policy towards Eastern Europe was a main driver for changes in the national diplomacy.

    Power generation is mainly performed by synchronous rotating machines which consume about a third of the world primary energy. Electric motors used in industrial applications convert about two thirds of this electricity. Therefore, synchronous machines are present everywhere at different scales, from micro-actuators of few micro-watts to thermo-mechanical production units of more than 1 GW, and represent a large variety of structures which have in common the synchronism between the frequency of the power supply currents and the relative movement of the fixed part with respect to the mobile part. Since several decades, these machines are more and more used as variable speed motors with permanent magnets. The advances in power electronics have contributed to the widening of their use in various applications with a huge range of powers. This article presents the general principle of operation of electromechanical converters of synchronous type: 1 - electromechanical conversion in electromagnetic systems: basic laws and elementary structures (elementary structure, energy conversion cycle, case of a system working in linear magnetic regime), rotating fields structure (magneto-motive force and Ferraris theorem, superficial air gap permeance, air gap magnetic induction, case of a permanent magnet inductor, magnetic energy and electromagnetic torque, conditions for reaching a non-null average torque, application to common cases); 2 - constitution, operation modes and efficiency: constitution and main types of synchronous machines, efficiency - analysis by similarity laws (other expression of the electromagnetic torque, thermal limitation in permanent regime, scale effects, effect of pole pairs number, examples of efficiencies and domains of use), operation modes.

    The past few years have seen the emergence of claims that the political determinants of health do not get due consideration and a growing demand for better insights into public policy analysis in the health research field. Several public health and health promotion researchers are calling for better training and a stronger research culture in health policy. The development of these studies tends to be more advanced in health promotion than in other areas of public health research, but researchers are still commonly caught in a naïve, idealistic and narrow view of public policy. This article argues that the political science discipline has developed a specific approach to public policy analysis that can help to open up unexplored levers of influence for public health research and practice and that can contribute to a better understanding of public policy as a determinant of health. It describes and critiques the public health model of policy analysis, analyzes political science's specific approach to public policy analysis, and discusses how the politics of research provides opportunities and barriers to the integration of political science's distinctive contributions to policy analysis in health promotion.

    Kim, Hyomin

    2014-04-01

    Korean nuclear energy regulatory policies started to change from earlier exclusively technocratic policies into open dialogues after several anti-nuclear protests in the 1990s. However, technocratic policies still coexist with the new regulatory orientation towards openness, participation and institutional accountability. This paper analyzes Korean nuclear regulatory policies since approximately 2005 as a blend of old and new governance. The aim of the paper is not to decide whether new nuclear governance is deliberative or not by completely reviewing Korean nuclear policies after the 2000s. Instead, it provides an empirical account of how seemingly more participatory processes in decision-making entail new problems while they work with and reproduce social assumptions of different groups of the public.

A modern decision - making process includes the whole procedure of decision making: setting the priorities of public policies, choosing options, instruments of public policy implementation, developing and adopting the respective legislative and normative acts, funding to implement these policies, conducting implementation actions and monitoring the impact of public policy decisions. Often the decision - making process in public administration is interpreted as a simple organization of the information and documents circuit. Therefore there arises the need to analyze the concept of decision making and propose solutions to improve it.

    Full Text Available Cluster­based entrepreneurship plays an important role in the economy of the 21st century. A regional cluster can be defined as a combination of 5 dimensions – single sector enterprises that cooperate and compete; supportive enterprises from a wide range of sectors; public and government institutions interested in economic development of the sector and region; other institutions, like research, education, finance and others and the fifth is regional dimension, which combines all four previously mentioned dimensions into one region. From the literature review standpoint, the findings of the authors show that cluster ­based entrepreneurship has an important role in stimulating the firm’s performance, competitiveness and innovation. Authors’ findings show that cluster concept is implemented in the EU policy planning documents at all levels, while in the country level cluster policy is not a single policy issue, but is implemented in industry, regional and other policy aspects. Example from Latvia shows that in recent years cluster­based entrepreneurship plays an important, if not central, role in policy planning documents, while evidence from Northern Cyprus shows that the importance attached to the concept of cluster­based economic development has not yet surfaced in the policy documents. Learning from experience of the EU and Latvia, the authors in cooperation with experts from University of Mediterranean Karpasia suggest policy makers in Northern Cyprus to implement cluster­based entrepreneur­ ship ideas in the policy documents using the bottom­up approach. In this way cluster based entrepreneurship is implemented in policy planning documents in Northern Cyprus at region, industry and national level. This paper is the first attempt towards cluster concept recognition in Northern Cyprus and therefore the topic is opened for further discussions and recommendations. The target audience of this paper is policy makers in Northern Cyprus

    Though the problems translating or applying research in policy-making are legion, solutions are rare. As developing countries increase their capacities to develop effective local solutions to their health problems, they confront the research/policy dilemma. Yet few descriptive studies of research-policy links can be found from developing countries, and the relevance of European and North American models and data is questionable. We report the results of a descriptive study from Mexico of the relationship between health research and policy in four vertical programmes (AIDS, cholera, family planning, immunization). We interviewed 67 researchers and policy-makers from different institutions and levels of responsibility. We analyzed interviewee responses looking for factors that promoted or impeded exchanges between researchers and policy-makers. These were, in turn, divided into emphases on content, actors, process, and context. Many of the promoting factors resembled findings from studies in industrialized countries. Some important differences across the four programmes, which also distinguish them from industrialized country programmes, included extent of reliance on formal communication channels, role of the mass media in building social consensus or creating discord, levels of social consensus, role of foreign donors, and extent of support for biomedical versus social research. We recommend various ways to increase the impact of research on health policy-making in Mexico. Some of the largest challenges include the fact that researchers are but one of many interest groups, and research but one input among many equally legitimate elements to be considered by policy-makers. Another important challenge in Mexico is the relatively small role played by the public in policy-making. Further democratic changes in Mexico may be the most important incentive to increase the use of research in policy-making.

    Following a particular attention given to environmental issues over the last few decades, establishing proper developmental policies to increase electricity production from renewable energy (RE) has not only been an important issue but also a challenge for many countries. Feed-in Tariff (FIT) Policy is one of the tools that is being used to facilitate the development of RE. This research evaluated the economic, welfare and environmental impact of this policy on Iran's economy. Therefore, after developing an Economic-Energy-Environmental (E3) type of Hybrid General Equilibrium model, the effect of FIT policy was examined under different scenarios in order to find an optimal condition in which 10% of electrical energy could be produced from renewable resources. The comparison between the results showed that the application of subsidies to RE and the way the government finances these subsidies can affect the results of FIT policy. Meanwhile, regardless of the role considered for the impact of environmental factors, our policies under the scenario of technology neutral is the most efficient, as it has less impact on the decline of GDP of different sectors and also has less financial cost for government. - Highlights: • E3 type of Hybrid CGE model is used under two different financing policies. • Technology neutral and technology specific scenarios are applied to these policies. • Results show the effect of our policies and scenarios on the efficiency of FIT policy. • This efficiency comes from the impact on GDP balance and government's financial cost. • The results show that, the scenario of technology neutral is the most efficient.

    Full Text Available This article examines how the recent evolution of asylum migration has affected the construction of the European Common Foreign and Security Policy (EU-CFSP, taking the Greek case during the 2001-2012 period as a starting point. With this in mind, the normative progress of the EU-CFSP facing the reception of asylum seekers in Greece is analyzed, under the scope of what Barry Buzan and Ole Waever would call Securitization Process. Both legal and political frameworks on asylum migration in Greece and in the European Union are approached, in the context of the evolution of the EU-CFSP in three main areas: Neighborhood Policy, Development and Cooperation Policy, and Human Rights Protection. The conclusión points toward the partial influence of asylum migration in the configuration of the UE-CFSP during the studied period.

    Most governments have committed to the set of Sustainable Development Goals established by the United Nations (UN) to be achieved by 2030. Subsequently the governments have drafted, or are in process of drafting, policies and programmes which aim to answer to these global requests. South Africa provides a unique case study: despite economic growth, undernutrition has not improved when compared to other industrialised nations, while at the same time, diet-related non-communicable diseases and obesity have exponentially increased. Access to healthy food is a constitutional right of all South Africans, and towards increasing food security and improving population health, various policies, programmes and regulations have been developed and implemented by the government to rectify the situation. The paper presents an overview of food composition within these public health policies, programmes and regulations and unpacks the important role of accurate food composition data.

    Full Text Available Multifunctional allotment gardens are an important part of the green infrastructure of cities. In spite of this, they are given little attention in the plans and policies of cities. One of the major threats to the existence of allotment gardens within the spatial structure of cities is the pressure of investment, which results from an underestimation of the role of gardens. The task of preserving allotment gardens in the ecosystems of cities rests with the local spatial planning. Urban spatial policy towards allotment gardening is exemplified by the case study of Poznan. The bases for the analysis include the study of the conditions and directions of spatial planning, as the spatial policy document that sets forth the city and local spatial development plans, which are Acts of local laws.

    Integrating Natural and Social Sciences to Inspire Public Confidence in Radioactive Waste Policy Case Study: Committee on Radioactive Waste Management Implementing effective long-term radioactive waste management policy is challenging, and both UK and international experience is littered with policy and programme failures. Policy must not only be underpinned by sound science and technical rationale, it must also inspire the confidence of the public and other stakeholders. However, in today's modern society, communities will not simply accept the word of scientists for setting policy based purely on technical grounds. This is particularly so in areas where there are significant social and ethical issues, such as radioactive waste disposal. To develop and implement effective policy, governments, waste owners and implementing bodies must develop processes which effectively integrate both complex technical and scientific issues, with equally challenging social and ethical concerns. These integrating processes must marry often intricate technical issues with broad public and stakeholder engagement programmes, in programmes which can expect the highest levels of public scrutiny, and must invariably be delivered within challenging time and budget constraints. This paper considers a model for how such integrating processes can be delivered. The paper reviews, as a case study, how such challenges were overcome by the Committee on Radioactive Waste Management (CoRWM), which, in July 2006, made recommendations to the UK government for the establishment of a long-term radioactive waste policy. Its recommendations were underpinned by sound science, but also engendered public confidence through undertaking the largest and most significant deliberative public and stakeholder engagement programme on a complex policy issue in the UK. Effective decision-making was enabled through the integration of both proven and bespoke methodologies, including Multi-criteria Decision Analysis and

  7. A strategic approach to selecting policy mechanisms for addressing coal mine methane emissions: A case study on Kazakhstan

    Coal production globally is projected to grow in the foreseeable future. Countries with heavy reliance on coal could reduce methane and other emissions through the capture and utilization of coal mine methane (CMM) in the short and medium term, while they pursue structural and long-term economic changes. Several countries have successfully implemented policies to promote CMM capture and utilization; however, some countries still struggle to implement projects. This paper outlines key factors to consider in adapting policies for CMM mitigation. The authors propose an approach for selecting adequate mechanisms for stimulating CMM mitigation that involves reviewing global best practices and categorizing them functionally either as mechanisms needed to improve the underlying conditions or as CMM-specific policies. It is important to understand local policy frameworks and to consider whether it is more feasible to improve underlying policy conditions or to provide targeted incentives as an interim measure. Using Kazakhstan as a case study, the authors demonstrate how policymakers could assess the overall policy framework to find the most promising options to facilitate CMM projects. Kazakhstan’s emissions from underground coal mines have been increasing both in total and per tonne of coal production, while overall production has been declining. CMM mitigation presents an opportunity for the country to reduce its greenhouse gas emissions in the near and medium term, while the government pursues sustainable development goals. Analysis shows that policymakers in Kazakhstan can leverage existing policies to stimulate utilization by extending feed-in tariffs to cover CMM and by developing working methodologies for companies to obtain emission reduction credits from CMM projects.

  8. The persistence of cliques in the post-communist state. The case of deniability in drug reimbursement policy in Poland.

    Ozierański, Piotr; King, Lawrence

    2016-06-01

    This article explores a key question in political sociology: Can post-communist policy-making be described with classical theories of the Western state or do we need a theory of the specificity of the post-communist state? In so doing, we consider Janine Wedel's clique theory, concerned with informal social actors and processes in post-communist transition. We conducted a case study of drug reimbursement policy in Poland, using 109 stakeholder interviews, official documents and media coverage. Drawing on 'sensitizing concepts' from Wedel's theory, especially the notion of 'deniability', we developed an explanation of why Poland's reimbursement policy combined suboptimal outcomes, procedural irregularities with limited accountability of key stakeholders. We argue that deniability was created through four main mechanisms: (1) blurred boundaries between different types of state authority allowing for the dispersion of blame for controversial policy decisions; (2) bridging different sectors by 'institutional nomads', who often escaped existing conflicts of interest regulations; (3) institutional nomads' 'flexible' methods of influence premised on managing roles and representations; and (4) coordination of resources and influence by elite cliques monopolizing exclusive policy expertise. Overall, the greatest power over drug reimbursement was often associated with lowest accountability. We suggest, therefore, that the clique theory can be generalized from its home domain of explanation in foreign aid and privatizations to more technologically advanced policies in Poland and other post-communist countries. This conclusion is not identical, however, with arguing the uniqueness of the post-communist state. Rather, we show potential for using Wedel's account to analyse policy-making in Western democracies and indicate scope for its possible integration with the classical theories of the state. © London School of Economics and Political Science 2016.

    The growing number of people living with HIV/AIDS (PLWHA) in China points to an increased need for case management services of HIV/AIDS. This study sought to explore the challenges and enablers in shifting the HIV/AIDS case management services from Centers for Disease Control and Prevention (CDCs) to Community Health Service Centers (CHSCs) in urban China. A qualitative method based on the Health Policy Triangle (HPT) framework was employed to gain in-depth insights into four elements of the task shifting strategy. This included a review on published literature and health policy documents, 15 focus group discussions (FGDs) and 30 in-depth interviews (IDIs) with four types of key actors from three cities in China. A total of 78 studies and 17 policy files at the national, municipal and local levels were obtained and reviewed comprehensively. Three semi-structured interview guides were used to explore key actors' views on shifting the HIV/AIDS case management services to CHSCs. It is necessary and feasible for CHSCs to engage in case management services for PLWHA in local communities. The increasing number of PLWHA and shortage of qualified health professionals in CDCs made shifting case management services downwards to CHSCs an urgent agenda. CHSCs' wide distribution, technical capacity, accessibility and current practice enabled them to carry out case management services for PLWHA. However our findings indicated several challenges in this task shifting process. Those challenges included lack of specific policy and stable financial support for CHSCs, inadequate manpower, relatively low capacity for health service delivery, lack of coordination among sectors, PLWHA's fear for discrimination and privacy disclosure in local communities, which may compromise the effectiveness and sustainability of those services. Shifting the HIV/AIDS case management services from CDCs to CHSCs is a new approach to cope with the rising number of PLWHA in China, but it should be

    Continuing professional development is essential for professionals to remain competent, and for effective recruitment and retention. This paper reports a qualitative study of the effects of workplace policy on continuing professional development on a small, dispersed profession in a resource-challenged province, using the case example of occupational therapy in Nova Scotia. The study used a multi-methods design, theoretically based on institutional ethnography. Methods were critical appraisal of the literature, interview and focus group data collection with 28 occupational therapists and 4 health services administrators, and a review of workplace policy. The study identified a policy wall. Notable policies were those which defined who is responsible for continuing professional development, and which limited employee benefits and work flexibility options for those with family duties. It appears that a female-dominated profession, such as occupational therapy, may also face gender-based challenges. Suggestions are offered for workplace policy makers, unions, provincial regulatory organizations, and health professionals. The findings are generally applicable to any small, dispersed health profession operating in resource-challenged conditions.

  11. Utility of four public-policy models as applied to the case study of nuclear materials transportation through the Lehigh Valley

    1982-01-01

    This dissertation assesses four public-policy models by utilizing the case-study approach and personal interviews with the major participants in the public-policy process of Northampton County, Pennsylvania. Northampton County is part of the metropolitan region encompassing Lehigh and Northampton Counties, PA. It is known as the Lehigh Valley which is situated in eastern Pennsylvania. The hypotheses tested in this dissertation are: (1) individual participants have articulated policy models as their frame of reference which guides them in understanding the public policy process, and (2) there is no one best policy model to explain the public-policy process, but the combination of various policy models may improve the policy analysts' understanding of public policy. Results indicate that the major participants have articulated policy models as their frame of reference, but a polarized view of policy models exists for the participants. The second hypothesis was only partially confirmed since the combination of one or more models did not resolve the group/elite policy dilemma of the practitioners. By utilizing stratification theory in the analysis, the group versus elite conflict is clarified and the policy formation phase of the public policy process is understood with respect to the Northamton County Council

    Climate change is expected to affect the health of most populations in the coming decades, having the greatest impact on the poorest and most disadvantaged people in the world. The Pacific islands, including Fiji, are particularly vulnerable to the effects of climate change. The three major health impacts of climate change in Fiji explored in this study were dengue fever, diarrhoeal disease, and malnutrition, as they each pose a significant threat to human health. The aim of this study was to investigate to what extent the Fiji National Climate Change Policy, and a selection of relevant sectoral policies, account for these human health effects of climate change. The study employed a three-pronged policy analysis to evaluate: 1) the content of the Fijian National Climate Change Policy and to what extent health was incorporated within this; 2) the context within which the policy was developed; 3) the relevant processes; and 4) the actors involved. A selection of relevant sectoral policies were also analysed to assess the extent to which these included climate change and health considerations. The policy analysis showed that these three health impacts of climate change were only considered to a minor extent, and often indirectly, in both the Fiji National Climate Change Policy and the corresponding National Climate Change Adaptation Strategy, as well as the Public Health Act. Furthermore, supporting documents in relevant sectors including water and agriculture made no mention of climate change and health impacts. The projected health impacts of climate change should be considered as part of reviewing the Fiji National Climate Change Policy and National Climate Change Adaptation Strategy, and the Public Health Act. In the interest of public health, this should include strategies for combating dengue fever, malnutrition, and water-borne disease. Related sectoral policies in water and agriculture should also be revised to consider climate change and its impact on human

A Peutz–Jeghers polyp (PJP in a patient without pigmentation or a family history of the disease is called an isolated or solitary PJP. Individuals with PJS carry a very high risk of developing gastrointestinal (GI as well as extra-GI malignancies. This case report documents lesion multiplicity and their malignant potential in a young patient with PJS presenting in a serious condition for the first time.Case report: An 18-year-old female Egyptian patient was admitted with hematochezia and remarkable anemia. After appropriate resuscitation and consent, colonoscopic evaluation revealed seven pedunculated colonic polyps at the ascending and the transverse colon, and numerous variable-sized sessile polyps were scattered all over the colon. To establish hemostasis, endoscopic polypectomy for pedunculated polyps and argon plasma photocoagulation for the bleeding sessile polyps were performed. Histopathological examination revealed cecal adenocarcinoma in one specimen and two simultaneous in situ carcinoma at the transverse and the sigmoid colon in the mucosae of the excised histologically proven hamartomatous polyps. Additionally, one focal in situ carcinoma in the resected colon was detected.Conclusions: When considering the family history, serious GI neoplastic lesions may be unmasked in young patients with PJS who present with hematochezia, even in the absence of its characteristic mucocutaneous pigmented lesions. GI endoscopic surveillance programs should be adopted for diagnosed cases of PJS and their families. Genetic prenatal screening for early detection is the best option for

    The roles played by drive and response systems on generalized chaos synchronization (GS) are studied. And the generalized synchronization is classified, based on these roles, to three distinctive types: the passive GS which is mainly determined by the response system and insensitive to the driving signal; the resonant GS where phase synchronization between the drive and response systems is preceding GS; and the interacting GS where both the drive and response have influences on the status of GS. The features of these GS types and the possible changes from one types to others are investigated.

    2010-12-01

    Full Text Available Policy to address the environmental impacts of transportation fuel derived from conventional oil is frequently focused on the promotion of alternatives such as biofuels. While there are some biofuels that can be developed with relatively few impacts, others can result in broader, complex social concerns that should be included in the policy debate. These concerns include impacts arising from the conversion of natural landscapes and changes in food supply. To help inform policy development, this paper raises a series of questions to encourage a fuller debate and proposes a methodology to capture ethical risks related to the energy and environmental choices. This methodology should be applied to policies that encourage a transition to fuel alternatives for transportation – whether unconventional fossil fuels or corn ethanol.

  3. Finite-Time and Fixed-Time Cluster Synchronization With or Without Pinning Control.

    Science.gov (United States)

    Liu, Xiwei; Chen, Tianping

    2018-01-01

    In this paper, the finite-time and fixed-time cluster synchronization problem for complex networks with or without pinning control are discussed. Finite-time (or fixed-time) synchronization has been a hot topic in recent years, which means that the network can achieve synchronization in finite-time, and the settling time depends on the initial values for finite-time synchronization (or the settling time is bounded by a constant for any initial values for fixed-time synchronization). To realize the finite-time and fixed-time cluster synchronization, some simple distributed protocols with or without pinning control are designed and the effectiveness is rigorously proved. Several sufficient criteria are also obtained to clarify the effects of coupling terms for finite-time and fixed-time cluster synchronization. Especially, when the cluster number is one, the cluster synchronization becomes the complete synchronization problem; when the network has only one node, the coupling term between nodes will disappear, and the synchronization problem becomes the simplest master-slave case, which also includes the stability problem for nonlinear systems like neural networks. All these cases are also discussed. Finally, numerical simulations are presented to demonstrate the correctness of obtained theoretical results.

      We develop an algorithm to compute an optimal Q(s,S) policy for the joint replenishment problem when demands follow a compound correlated Poisson process. It is a non-trivial generalization of the work by Nielsen and Larsen (2005). We make some numerical analyses on two-item problems where we...... compare the optimal Q(s,S) policy to the optimal uncoordinated (s,S) policies. The results indicate that the more negative the correlation the less advantageous it is to coordinate. Therefore, in some cases the degree of correlation determines whether to apply the coordinated Q(s,S) policy...... or the uncoordinated (s,S) policies. Finally, we compare the Q(s,S) policy and the closely connected P(s,S) policy. Here we explain why the Q(s,S) policy is a better choice if item-demands are correlated....

In a small open economy such as Chile, these indicators may include in-flation misalignments, unemployment, GDP growth, money growth, the current account balance, exchange rate volatility and international re-serves. A neural network approach is used to establish the correspond-ing weights considered by the Board of the Central Bank of Chile dur-ing the per...

    The prevalence of overweight and obesity is a rapidly growing threat to public health in both Morocco and Tunisia, where it is reaching similar proportions to high-income countries. Despite this, a national strategy for obesity does not exist in either country. The aim of this study was to explore the views of key stakeholders towards a range of policies to prevent obesity, and thus guide policy makers in their decision making on a national level. Using Multicriteria Mapping, data were gathered from 82 stakeholders (from 33 categories in Morocco and 36 in Tunisia) who appraised 12 obesity policy options by reference to criteria of their own choosing. The feasibility of policies in practical or political terms and their cost were perceived as more important than how effective they would be in reducing obesity. There was most consensus and preference for options targeting individuals through health education, compared with options that aimed at changing the environment, i.e. modifying food supply and demand (providing healthier menus/changing food composition/food sold in schools); controlling information (advertising controls/mandatory labelling) or improving access to physical activity. In Tunisia, there was almost universal consensus that at least some environmental-level options are required, but in Morocco, participants highlighted the need to raise awareness within the population and policy makers that obesity is a public health problem, accompanied by improving literacy before such measures would be accepted. Whilst there is broad interest in a range of policy options, those measures targeting behaviour change through education were most valued. The different socioeconomic, political and cultural contexts of countries need to be accounted for when prioritizing obesity policy. Obesity was not recognized as a major public health priority; therefore, convincing policy makers about the need to prioritize action to prevent obesity, particularly in Morocco, will be

    In this study I examined the implementation of tax policy reforms at Uganda Revenue Authority. In particular, I examined the impact of the tax policy reforms implemented since the restructuring of Uganda Revenue Authority in 2005. Although Uganda's taxation system is a vital area of study, it has not gotten enough attention from researchers. This is because, in the Ugandan and generally African developing countries context, taxation involves vital and, to a large ex...

    The Lebanese Electric Power System (LEPS) has been suffering from technical and financial deficiencies for decades and mirrors the problems encountered in many developing countries suffering from inadequate or no power systems planning resulting in incomplete and ill-operating infrastructure, and suffering from effects of political instability, huge debts, unavailability of financing desired projects and inefficiency in operation. The upgrade and development of the system necessitate the adoption of a comprehensive energy policy that introduces solutions to a diversity of problems addressing the technical, financial, administrative and governance aspects of the system. In this paper, an energy policy for Lebanon is proposed and evaluated based on integration between energy modeling and financial modeling. The paper utilizes the Load Modification Technique (LMT) as a probabilistic tool to assess the impact of policy implementation on energy production, overall cost, technical/commercial losses and reliability. Scenarios reflecting implementation of policy projects are assessed and their impacts are compared with business-as-usual scenarios which assume no new investment is to take place in the sector. Conclusions are drawn on the usefulness of the proposed evaluation methodology and the effectiveness of the adopted energy policy for Lebanon and other developing countries suffering from similar power system problems. - Highlights: ► Evaluation methodology based on a probabilistic simulation tool is proposed. ► A business-as-usual scenario for a given study period of the LEPS was modeled. ► Mitigation scenarios reflecting implementation of the energy policy are modeled. ► Policy simulated and compared with business-as-usual scenarios of the LEPS. ► Results reflect usefulness of proposed methodology and the adopted energy policy.

  12. Noncoherent Symbol Synchronization Techniques

    Traditional methods for establishing symbol synchronization (sync) in digital communication receivers assume that carrier sync has already been established, i.e., the problem is addressed at the baseband level assuming that a 'perfect' estimate of carrier phase is available. We refer to this approach as coherent symbol sync. Since, for NRZ signaling, a suppressed carrier sync loop such as an I-Q Costas loop includes integrate-and-dump (I and D) filters in its in-phase (1) and quadrature (Q) arms, the traditional approach is to first track the carrier in the absence of symbol sync information, then feed back the symbol sync estimate to these filters, and then iterate between the two to a desirable operating level In this paper, we revisit the symbol sync problem by examining methods for obtaining such sync in the absence of carrier phase information, i.e., so-called noncoherent symbol sync loops. We compare the performance of these loops with that of a well-known coherent symbol sync loop and examine the conditions under which one is preferable over the other.

    The introduction of new policies can evoke strong emotional reactions by the public. Yet, social-psychological research has paid little attention to affective determinants of individual-level policy acceptance. Building on recent theoretical and empirical advances around emotions and decision-making, we evaluate how people's trust and integral emotions function as important antecedents of cognitive evaluations, and subsequent acceptance of policies. We test our hypotheses within a sample of Irish citizens (n = 505), who were subject to the introduction of water charges in 2015. In line with our hypotheses, results show that general trust in government shapes emotions regarding water charges, which in turn, directly and via expected costs and benefits, influence policy acceptance. Additionally, we find that negative emotions have a larger direct effect on policy acceptance than positive emotions. Specifically, 'anger' was the main negative emotion that influenced the acceptance of the water charge. We conclude by discussing directions for future research around emotions and policy acceptance. © 2018 The British Psychological Society.

    We investigate effects of government policy uncertainty on stock prices, reflecting tension between ‘private interest’ (economic benefits) and ‘public interest’ arguments over uranium mining. Using a sample of Australian-listed uranium firms from January 2005 through June 2008, we document a positive contemporaneous correlation between stock returns and volatility and two measures of government policy uncertainty, proxied by the spread in voters' opinion polls between the two major political parties and a news-based sentiment index. Event-study results show significant stock price reactions to key uranium-related policy events, with cross-sectional variation in event returns predicted by models incorporating firm- and project-level characteristics. Our research design and findings may inform future research on the capital market effects of government policy uncertainty in other regulated industries. - Highlights: • Government policy uncertainty has direct effects on stock prices of uranium explorers. • Stock returns are positively related to the spread in two-party-preferred voting intention. • Stock volatility is positively related to a uranium news-based sentiment index. • Event-study results show significant market reaction to key uranium policy events.

  15. Can trust in politicians explain individuals' support for climate policy? The case of CO2 tax

    Hammar, Henrik; Jagers, Sverker C.

    2006-01-01

    This article provides an analysis of the support for public policies from a trust perspective. The empirical focus is on the use of a tax on carbon dioxide (CO 2 ), a policy tool aimed at coordinating national emissions targets in Sweden. Among economists and experts in the field of climate policy, a CO 2 tax is viewed as a cost-effective policy. The policy problem is that public support for CO 2 taxes is very low, leaving policy makers with high-cost options. Apart from traditional explanatory variables such as demographic factors, level of education, ideology and self-interest, what can explain this public opposition? Using individual level data, we analyse whether support for increases in the CO 2 tax on gasoline can be explained by citizens' generalized trust in other individuals (who they do not necessarily know) or by their trust in politicians. We find that only the latter measure gains support in a regression analysis. Moreover, when splitting the sample into high-trusting and low-trusting individuals, we find that high-trusting individuals who have access to a car (compared with those without access) are statistically no more likely to resist increases in CO 2 taxes than people without access to a car. Rather, it is individuals with access to a car and who do not trust their politicians who are likely to resist CO 2 taxes. (Author)

    In the case of digital piracy should rights be publicly or privately enforced? The emergence of large-scale anti-piracy laws and the existence of non-monitored illegal channels raise important issues for the design of digital anti-piracy policies. In this paper, we study the impact of these two enforcement settings (public vs. private) in the presence of an illegal non-monitored outside option for users. Taking account of market outcomes, we show that in both cases, the optimal strategies of ...

    Primary cancer arising from multiple organs is a well known fact. Synchronous tumours have been most commonly associated with kidney cancer. Bladder, prostate, colorectal and lung cancer are the most common synchronous primaries with Renal Cell Carcinoma (RCC) identified till date. We found metachronous tumours of breast with RCC in literature search which included both metastatic tumours as well second primaries. Overall, 25 cases of metastatic breast tumours and eight cases of second primary in previously treated RCC have been reported in the literature. Here, we are reporting a case of synchronous presentation of carcinoma breast with RCC which is very rare because most of the multiple malignancies reported in the literature are metastatic tumours or metachronous breast malignancy with RCC.

    The structure of many real-world systems is best captured by networks consisting of several interaction layers. Understanding how a multilayered structure of connections affects the synchronization properties of dynamical systems evolving on top of it is a highly relevant endeavor in mathematics and physics and has potential applications in several socially relevant topics, such as power grid engineering and neural dynamics. We propose a general framework to assess the stability of the synchronized state in networks with multiple interaction layers, deriving a necessary condition that generalizes the master stability function approach. We validate our method by applying it to a network of Rössler oscillators with a double layer of interactions and show that highly rich phenomenology emerges from this. This includes cases where the stability of synchronization can be induced even if both layers would have individually induced unstable synchrony, an effect genuinely arising from the true multilayer structure of the interactions among the units in the network.

    A popular method of symbol synchronization exploits one aspect of generalized harmonic analysis, normally referred to as the cross-spectrum. Utilizing nonlinear techniques, the input symbol energy is effectively concentrated onto multiples of the symbol clock frequency, facilitating application of conventional phase lock synchronization techniques. A general treatment of the cross-spectrum technique is developed and shown to be applicable across a broad class of symbol modulation formats. An important specific symbol synchronization application is then treated, focusing the general development to provide both insight and quantitative measure of the performance impact associated with variation in these key synchronization parameters: symbol modulation format, symbol transition probability, symbol energy to noise density ratio, and symbol rate to filter bandwidth ratio.

  20. Synchronization of hypernetworks of coupled dynamical systems

    We consider the synchronization of coupled dynamical systems when different types of interactions are simultaneously present. We assume that a set of dynamical systems is coupled through the connections of two or more distinct networks (each of which corresponds to a distinct type of interaction), and we refer to such a system as a dynamical hypernetwork. Applications include neural networks made up of both electrical gap junctions and chemical synapses, the coordinated motion of shoals of fish communicating through both vision and flow sensing, and hypernetworks of coupled chaotic oscillators. We first analyze the case of a hypernetwork made up of m = 2 networks. We look for the necessary and sufficient conditions for synchronization. We attempt to reduce the linear stability problem to a master stability function (MSF) form, i.e. decoupling the effects of the coupling functions from the structure of the networks. Unfortunately, we are unable to obtain a reduction in an MSF form for the general case. However, we show that such a reduction is possible in three cases of interest: (i) the Laplacian matrices associated with the two networks commute; (ii) one of the two networks is unweighted and fully connected; and (iii) one of the two networks is such that the coupling strength from node i to node j is a function of j but not of i. Furthermore, we define a class of networks such that if either one of the two coupling networks belongs to this class, the reduction can be obtained independently of the other network. As an example of interest, we study synchronization of a neural hypernetwork for which the connections can be either chemical synapses or electrical gap junctions. We propose a generalization of our stability results to the case of hypernetworks formed of m ⩾ 2 networks. (paper)
