Purpose The purpose of this paper is to examine the pattern, duration and country-level determinants of global agri-food export competitiveness of 23 major global agri-food trading countries. Design/methodology/approach A large panel data set is compiled to facilitate assessment of the pattern, duration and country-level determinants of global agri-food export competitiveness using a revealed comparative advantage index. Findings The results suggest that the duration of revealed comparative advantage is heterogeneous at the agri-food product level. Long-term survival rates as revealed by the comparative advantage indices are among the highest for the Netherlands, France, Belgium, the USA, Argentina and New Zealand. The level of economic development, the share of agricultural employment, subsidies to agriculture and differentiated consumer agri-food products increase the likelihood of failure in the duration of comparative advantage, while the abundance of agricultural land and export diversification reduce that likelihood. Originality/value The framework is conceptually innovative in how it models the likelihood of failure in the duration of comparative advantage and assesses implications. Export competitiveness is a crucial factor in long-term global farm business survival as it fosters opportunities for business prosperity on global markets.

ABSTRACTViable methanogens have been detected in dry, aerobic environments such as dry reservoir sediment, dry rice paddies and aerobic desert soils, which suggests that methanogens have mechanisms for long-term survival in a desiccated state. In this study, we quantified the survival rates of the methanogenic archaeonMethanosarcina barkeriafter desiccation under conditions equivalent to the driest environments on Earth and subsequent exposure to different stress factors. There was no significant loss of viability after desiccation for 28 days for cells grown with either hydrogen or the methylotrophic substrates, but recovery was affected by growth phase, with cells desiccated during the stationary phase of growth having a higher rate of recovery after desiccation. Synthesis of methanosarcinal extracellular polysaccharide (EPS) significantly increased the viability of desiccated cells under both anaerobic and aerobic conditions compared with that of non-EPS-synthesizing cells. DesiccatedM. barkeriexposed to air at room temperature did not lose significant viability after 28 days, and exposure ofM. barkerito air after desiccation appeared to improve the recovery of viable cells compared with that of desiccated cells that were never exposed to air. DesiccatedM. barkeriwas more resistant to higher temperatures, and although resistance to oxidative conditions such as ozone and ionizing radiation was not as robust as in other desiccation-resistant microorganisms, the protection mechanisms are likely adequate to maintain cell viability during periodic exposure events. The results of this study demonstrate that after desiccationM. barkerihas the innate capability to survive extended periods of exposure to air and lethal temperatures.

Purpose The purpose of this paper is to analyze international orange trade as different types of orange juice seem to obtain the favor of newer food consumption patterns as opposed to fresh oranges. In addition, the authors will outline market tendencies that could be useful to stakeholders interested in any way in the sector. Design/methodology/approach This document uses the Lafay index (LFI) in order to evaluate the intra-sectoral trade specialization; however, the social network analysis (SNA) approach is used to connect the international trade relations and to refine, classify and prioritize the countries having a central role in the orange juice world trade network. For both indexes, UNCOMTRADE has been used. Findings The findings show that the growing orange juice trade is the leading global growth factor as opposed to the sale of fresh oranges. It appears that major trade revenues come from orange juice concentrate (Frozen Concentrated Orange Juice (FCOJ)). Business takes place mostly in Europe. Originality/value This study shows for the first time that the current orange juice export competitiveness is crucial to the long-term survival of the orange sector. This study valuably contributes to the less known literature regarding FCOJ and Not From Concentrate orange juice trade relevance.

Traditionally Handloom sector was the backbone of Indian industry and the essence of Indian civilization and culture. After the evaluation of industrialization the handloom industry is facing stiff competition with power loom and consistently upgrading technology and other industries, nevertheless, the handloom industry has the significant contribution in the India’s international as well as intra-national trade. With this background, the present paper will examine the comparative advantage of Indian handloom industry with respect to global economy by applying the Ballasa (1965) index of Revealed Comparative Advantage (RCA) and also examine the export competitiveness by using Porter Export competitiveness model, using highly disaggregated data from 2004 - 2013 by using WITS (World Integrated Trade Solution) WTO data set and the export performance of Indian handloom products during 2013-18 from the handloom export promotion council data set. Under the International classification of commodities at six-digit level, there are 21 groups are classified as the handloom products. This paper has calculated and analyzed the Revealed Comparative Advantage (RCA) of all handloom commodities at disaggregate level. Result shows that India has high revealed comparative advantage in almost all the handloom products, it’s in total 22 hand product India has high comparative advantage in 15 products and having a slight disadvantage in only 6 handloom products in studied and analyzed period of subsequent year 2004-2013. However, the export competitiveness indices show also the export advantage edge in handloom products. It shows that there is high potentiality of growth in handloom industry but lagging under capacity it lies behind it. This paper suggests government initiatives for the realization of handloom sector at its optimum level.

Purpose The purpose of this study is to identify US textile and apparel (TAP) products and categories that demonstrate export comparative advantage and their respective country destinations. Design/methodology/approach Revealed comparative advantage (RCA) and normalized revealed comparative advantage (NRCA) in the long term (1996-2016) and short term (2010-2016) using two-digit Harmonized Commodity Description and Coding System codes (HS codes) provide an insight into export advantage of TAP products. Non-parametric rank correlation (i.e. Spearman rank correlation) tests consistency between RCA and NRCA. Subsequently, NRCA using four-digit HS codes identify textile sub-categories with export comparative advantage. Bilateral trade data identify export destinations for sub-categories that indicate US export comparative advantage in the short term. Findings Aggregated product-level comparison of RCA and NRCA ranking indicates a consistent positive correlation between the two indices. The disaggregated findings reveal cotton fiber HS5201, artificial filament tow HS5502, non-wovens HS5603, cotton yarn HS5205, carpet and other floor coverings HS5703 and worn clothing HS6309 as sources of US TAP export advantage. Originality/value This research provides a comprehensive, current analysis of the US competitive position within the TAP global environment. Incorporation of NRCA into the study’s design demonstrates the flexibility of this measure in a new industry context.

Postoperative Irradiation

✓ The postoperative survival time of 170 nonrandomized patients treated for cerebral oligodendrogliomas in Norway from 1953 to 1977 was studied. Survival times were significantly prolonged if postoperative irradiation was performed in addition to surgery (median survival time 26.5 vs. 38 months, p = 0.039). In the group without postoperative radiotherapy, the 5-year rate of survival was 27% compared with 36% in the irradiated patients. The respective survival rates after 8 years were 14% versus 17%; thus, there was little effect on long-term survival. Irradiation appears not to be of benefit after “total” removal. Patients with partly resected lesions appeared to benefit from postoperative radiotherapy; the median survival period after subtotal tumor resection was 37 months with and 26 months without radiotherapy (p = 0.0089). The findings also indicate that irradiation doses between 40 and 50 Gy were as effective as doses between 50 and 60 Gy in increasing the patients' probability of surviving 5 years after subtotal tumor resection. Since the risk of radiation necrosis is proportional to the dose applied, the lower dose is recommended. These conclusions were also valid when adjustments were made for prognostically significant histological and clinical features.

Purpose This study aims to fundamentally focus on the comparative advantage measurement and the trend of change in the international competitiveness of five Thai economic products exporting to the People’s Republic of China during the first half of the 2010s via the analysis of the revealed comparative advantage (RCA) index and market share. Design/methodology/approach The RCA index has been computed to show the comparative advantages of the product to a certain extent: whether it is cost-effective to produce that product in a certain location compared to opportunity cost of the resources in producing that product. The data set of number and value of five important export products from Thailand to China during 2010-2013 has been obtained from the Thai Ministry of Commerce and Thai-Chinese Business Information Centre. Findings The study reveals that of these five important economic products, cassava has the highest comparative advantage and continues to have a rapid growth trend, whilst computer equipment and components have been shown to have comparative disadvantage and the lowest comparative advantage index scores. Research limitations/implications Measuring with various sophisticated indices may provide clearer results. Also, according to unavailability of data set, the four-year period may not be able to show the long-term trend of competitiveness. Future studies are encouraged to study in the longer-term period with numerous indices. Practical implications The research also provides policy implications and measures to develop each sector to enhance competitiveness. Originality/value This is the original attempt to use both indices to assess the competitiveness of important Thai exports to the Chinese market.

Refractory Hodgkin Lymphoma

Introduction: Hodgkin lymphoma is a curable lymphoma with an 80–90% long-term survival, however, 30% of the patients develop relapse. Only half of relapsed patients can be cured with autologous stem cell transplantation. Aim: The aim of the authors was to analyze survival rates and incidence of relapses among Hodgkin lymphoma patients who were treated between January 1, 1980 and December 31, 2014. Novel therapeutic options are also summarized. Method: Retrospective analysis of data was performed. Results: A total of 715 patients were treated (382 men and 333 women; median age at the time of diagnosis was 38 years). During the studied period the frequency of relapsed patients was reduced from 24.87% to 8.04%. The numbers of autologous stem cell transplantations was increased among refracter/relapsed patients, and 75% of the patients underwent transplantation since 2000. The 5-year overall survival improved significantly (between 1980 and 1989 64.4%, between 1990 and 1999 82.4%, between 2000 and 2009 88.4%, and between 2010 and 2014 87.1%). Relapse-free survival did not change significantly. Conclusions: During the study period treatment outcomes improved. For relapsed/refractory Hodgkin lymphoma patients novel treatment options may offer better chance for cure. Orv. Hetil., 2015, 156(45), 1824–1833.

Object. The study was conducted to determine the association between dual-isotope single-photon emission computerized tomography (SPECT) scanning and histopathological findings of tumor recurrence and survival in patients treated with high-dose radiotherapy for glioblastoma multiforme. Methods. Studies in which SPECT with 201Tl and 99mTc-hexamethypropyleneamine oxime (HMPAO) were used were performed 1 day before reoperation in 47 patients with glioblastoma multiforme who had previously been treated by surgery and high-dose radiotherapy. Maximum uptake of 201Tl in the lesion was expressed as a ratio to that in the contralateral scalp, and uptake of 99mTc-HMPAO was expressed as a ratio to that in the cerebellar cortex. Patients were stratified into groups based on the maximum radioisotope uptake values in their tumor beds. The significance of differences in patient gender, histological characteristics of tissue at reoperation, and SPECT uptake group with respect to 1-year survival was elucidated by using the chi-square statistic. Comparisons of patient ages and time to tumor recurrence as functions of 1-year survival were made using the t-test. Survival data at 1 year were presented according to the Kaplan—Meier method, and the significance of potential differences was evaluated using the log-rank method. The effects of different variables (tumor type, time to recurrence, and SPECT grouping) on long-term survival were evaluated using Cox proportional models that controlled for age and gender. All patients in Group I (201Tl ratio < 2 and 99mTc-HMPAO ratio < 0.5) showed radiation changes in their biopsy specimens: they had an 83.3% 1-year survival rate. Group II patients (201T1 ratio < 2 and 99mTc-HMPAO ratio of ≥ 0.5 or 201Tl ratio between 2 and 3.5 regardless of 99mTc-HMPAO ratio) had predominantly infiltrating tumor (66.6%); they had a 29.2% 1-year survival rate. Almost all of the patients in Group III (201Tl ratio > 3.5 and 99mTc-HMPAO ratio ≥ 0.5) had solid tumor (88.2%) and they had a 6.7% 1-year survival rate. Histological data were associated with 1-year survival (p < 0.01); however, SPECT grouping was more closely associated with 1-year survival (p < 0.001) and was the only variable significantly associated with long-term survival (p < 0.005). Conclusions. Dual-isotope SPECT data correlate with histopathological findings made at reoperation and with survival in patients with malignant gliomas after surgical and high-dose radiation therapy.

Both organizational and management research suggest that schools and their leaders need to be ambidextrous to secure prosperity and long-term survival in dynamic environments characterized by competition and innovation. In this context, ambidexterity refers to the ability to simultaneously pursue exploitation and exploration and thus to deliver efficiency, control and incremental improvements while embracing flexibility, autonomy and discontinuous innovation. Using a unique, randomized and representative data set of N = 405 principals, we present findings on principals’ exploitation and exploration. The results indicate: (a) that principals engage far more often in exploitative than in explorative activities; (b) that exploitative activities in schools are executed at the expense of explorative activities; and (c) that explorative and ambidextrous activities of principals are positively associated with the (perceived) competition between schools. The study brings a novel perspective to educational research and demonstrates that applying the concept of ambidexterity has the potential to further our understanding of effective educational leadership and management.
