Authors: WEI JIAJIA , XIONG GUOCHUN , ZOU CHUNYU , PAN BO , XU WEIBIN
Published: October 2016

Oreocharis curvituba, a new species of Gesneriaceae from Guangxi, China, is described and illustrated. It resembles O. stenosiphon and O. magnidens in the leaf characters, but it differs from the latter by its corolla with tube slightly curved, marked with purple star and a ring of glandular hairs at mouth.
Rhinobatos manai sp. nov., a new species of guitarfish (Rhinopristiformes: Rhinobatidae) from New Ireland, Papua New Guinea
Authors: WHITE WILLIAM T. , LAST PETER R. , NAYLOR GAVIN J.P.
Published: October 2016

A new species of guitarfish (Rhinobatos) is described based on a single specimen collected in 2014 from off New Ireland in Papua New Guinea. This specimen represents the first record of the family Rhinobatidae in Papua New Guinean waters. Based on molecular data, the new species appears to be most similar to Rhinobatos whitei (Philippines) and Rhinobatos sainsburyi (northern Australia), but is distinguished based on its coloration, morphology and certain meristic characters.
Reducing the Stigma of Depression Among Asian Students
Authors: Botha Francois B. , Shamblaw Amanda L. , Dozois David J. A.
Published: October 2016

In North America, Asians reliably report higher levels of stigma toward people with depression than do Europeans. Possible methods of reducing this discrepancy have rarely been explored. Asian undergraduate students ( n = 132) were presented with one of four antistigma videos with two actresses: one portraying a student with depression and the other a professor. The videos used the concept of social proof, presenting either positive or negative descriptive norms, to effect change in stigma, measured by social distance. It was hypothesized that the positive descriptive norms intervention would show significantly greater positive change in social distance compared with the negative descriptive norms intervention. All videos were effective in reducing preferred social distance toward people with depression relative to the control condition. The effectiveness of the positive descriptive norm video was mediated through descriptive norms and self-efficacy. The effectiveness of the negative descriptive norm video was mediated through injunctive norms and perceived value of support. The findings can help guide interventions that aim to encourage social engagement with people with depression among Asian student populations. Manipulating social norms and increasing self-efficacy may be especially effective.

Authors: Bell Douglas JW , He Cheng , Pauli John L , Naidoo Rishendran
Published: October 2016

Maroteaux-Lamy syndrome is a very rare multisystem disorder. Cardiac valve surgery is common in these patients who present a unique set of perioperative and intraoperative challenges to the surgeon and treating team. We describe successful mitral valve replacement using an inverted aortic prosthesis in a 29-year-old lady with Maroteaux-Lamy syndrome, with a good result at 10 months.
Ulrich Beck: Some Ideas for Tomorrow
Authors: Wieviorka Michel
Published: October 2016

Ulrich Beck was both a committed intellectual and one of the most original and innovative thinkers in our times, bringing new ideas and knowledge about the world in which we live. Among his more recent conceptual tributes, one finds such concepts as cosmopolitization of the world, the idea that social science has a lot to say about love in the second modernity, the importance of the city in a globalized world, and the notion of ‘emancipatory catastrophism’.
Proximity of public schools to major highways and industrial facilities, and students’ school performance and health hazards
Authors: Kweon Byoung-Suk , Mohai Paul , Lee Sangyun , Sametshaw Amy M
Published: October 2016

Children with consistent exposure to air pollution have increased asthma, chronic respiratory problems, and neurobehavioral dysfunction. However, many schools are located in close proximity to highways and industrial facilities which are key sources of air pollution to children. The goal of this study is to explore the association between the proximity from schools to highways and industrial facilities, and children’s school performance and health hazards. We measured the distances from 3,660 Michigan public schools to highways and industrial facilities, and linked these to the Michigan Educational Assessment Program test performance rate and the National Air Toxics Assessment’s respiratory and neurological hazards. We found that schools located closer to highways and industrial facilities had higher risks of respiratory and neurological diseases than those located farther away. We also found that schools located closer to major highways had a higher percentage of students failing to meet the state standards than the latter after controlling for the location of schools, student expenditure, school size, student–teacher ratio, and free lunch enrollment. In addition, a larger percentage of black, Hispanic, or economically disadvantaged children attended schools nearest to pollution emissions than white students.
Effect of Swim Training on the Physical Characteristics of Competitive Adolescent Swimmers
Authors: Hibberd Elizabeth E. , Laudner Kevin G. , Kucera Kristen L. , Berkoff David J. , Yu Bing , Myers Joseph B.
Published: October 2016

Background:

Subacromial space distance and forward head and shoulder posture are common characteristics resulting from swim training. These alterations can cause abnormal scapular kinematics and positioning, potentially increasing compression of structures in the subacromial space and increasing the risk for the development of swimmer’s shoulder.

Purpose:

To evaluate the effect of the swim training season on subacromial space distance and forward head and forward shoulder posture as well as to determine the relationship between these variables.

Study Design:

Cohort study; Level of evidence, 2.

Methods:

Included in the study were 43 competitive adolescent swimmers and 29 nonoverhead adolescent athletes (controls) who were not currently experiencing any shoulder, neck, or back pain that limited their participation in sports activity. All participants were evaluated 3 times: once before the start of the swim training season and then at 2 follow-up sessions 6 and 12 weeks after the initial testing session. At each testing session, each participant completed a physical examination that included evaluation of posture and subacromial space distance.

Results:

Swimmers had significantly greater decreases in subacromial space distance during the training season compared with nonoverhead athletes. Swimmers also demonstrated significantly greater increases in forward shoulder posture compared with nonoverhead athletes. A significant relationship was noted between changes in forward shoulder posture and changes in subacromial space distance from the baseline testing session to the assessment 6 weeks after baseline assessment. As forward shoulder posture increased, subacromial space significantly decreased.

Conclusion:

Because of their training load, swimmers experience a decrease in subacromial space distance and an increase in forward shoulder posture over the course of 12 weeks of training, potentially making these athletes more vulnerable to the development of shoulder pain and injury.
Psychometric Validity and Gender Invariance of the Academic Buoyancy Scale in the Philippines: A Construct Validation Approach
Authors: Datu Jesus Alfonso D. , Yang Weipeng
Published: October 2016

The current study examined the psychometric validity and gender invariance of the Academic Buoyancy Scale in the Philippines through a construct validation approach. In terms of within-network construct validity, our results demonstrated that the unidimensional model of academic buoyancy significantly fit the current sample and was invariant across gender. Male students scored significantly higher than female students on academic buoyancy. Regarding between-network construct validity, our results revealed that academic buoyancy was positively associated with behavioral and emotional engagement. Implications of the findings of the study are discussed.
The Role of Depression in the Relationship Between Psychological and Physical Intimate Partner Violence
Authors: Barros-Gomes Patrícia , Kimmes Jonathan , Smith Erika , Cafferky Bryan , Stith Sandra , Durtschi Jared , McCollum Eric
Published: October 2016

Physical and psychological intimate partner violence (IPV) are significant public health concerns often associated with negative consequences for individuals, families, and society. Because IPV occurs within an interpersonal relationship, it is important to better understand how each partner’s depressive symptoms, marital satisfaction, and psychological and physical IPV are interlinked. The purpose of this study was to identify actor and partner effects in a dyadic data analysis association between marital satisfaction and depressive symptoms, its links to psychological IPV, and then to physical IPV. Guided by the social information processing model, this study has implications for understanding the processes leading to various types of IPV in people seeking couples therapy. Using cross-sectional data from 126 heterosexual couples, we conducted an actor–partner interdependence model (APIM) to test actor and partner effects. Indirect actor and partner effects were also assessed. More depressive symptoms were associated with lower marital satisfaction. More depressive symptoms were generally linked with increased perpetration of psychological and physical IPV. Psychological IPV was associated with an individual’s use of physical IPV. Effect sizes were moderate to large in magnitude. Four specific indirect effects were identified from depressive symptoms to psychological IPV to physical IPV. Depressive symptoms may be an important factor related to psychological and physical IPV for males and females. Implications include assessing for and treating depression in both partners, and discussing preferred ways of supporting each other that do not include psychological or physical IPV.
Single-stream processing technique for in situ polymerization of glass fiber/polyamide-6 laminates
Authors: Barfknecht Peter W , Martin Justin , Pillay Brian , Vaidya Uday K , Gray Gary M
Published: October 2016

Ring-opening polymerization of anionic polyamide-6 (APA-6) requires both an activator and an initiator for the reaction to occur. Typical processing techniques for liquid-molded thermoplastic composite laminates involve infusion of the reinforcement with a premixed monomer solution containing both activator and initiator species. The technique described here is a step toward simplification and automation of the in situ polymerization process for composite laminates. By depositing the initiation functional group onto the reinforcement, infusion of a single stream of inert monomer solution is possible. The technique simplifies the processing equipment required and reduces the risk of contamination. Two separate methodologies derived from a silane and a diisocyanate were investigated. The soluble diisocyanate method was used to successfully demonstrate the single-stream APA-6 processing technique. Glass fiber surface-initiated polymerization was also demonstrated using the silane-derived initiator. The findings represent the first steps toward a new processing paradigm of APA-6 composites.
Similar Populations, Differing Service Levels: Exploring Factors That Drive Variability in the Provision of Speech-Language Services
Authors: Sylvan Lesley
Published: October 2016

This research contrasts two urban school districts that serve similar populations yet vary notably with respect to the provision of speech and language services. The results suggest that variation in the provision of speech-language services is driven by district-level variations in budgetary and legal contexts as well as procedural differences. This article explores how federal and state education policies, district policies, budgetary and legal pressures, as well as procedural differences work in concert to shape the implementation of Individuals With Disabilities Education Act with respect to the provision of services to students with speech-language impairments.
The Economic Evaluation of Food Stamps: An Intertemporal Analysis with Nonlinear Budget Constraints
Authors: Caniglia Alan S.
Published: October 2016

In-kind programs are typically evaluated using a one-period model. This causes certain issues to be obscured, such as the effect on an efficiency analysis of the length of a family's participation in the program. In this article an intertemporal model with a nonlinear budget frontier and a simulation methodology are used to investigate, for hypothetical participants in the food stamp program, how the benefit-subsidy ratio changes as the length of participation increases. The results indicate that this ratio may either rise or fall, with a significant decline being a possibility.
Free-Riding versus Paying under Uncertainty
Authors: Fon Vincy
Published: October 2016

An uncertainty model with a choice of free-riding is presented. The model does not provide theoretical justification to support a conclusion that rational individuals will always choose to free-ride. In the case of a contributor, a smaller likelihood of the undesirable event and a less effective benefit production function both lead to a smaller contribution by an individual. However, an individual who becomes more risk-averse, depending on the probability of the undesirable event and the effectiveness of the benefit production function, might choose to make either a larger or smaller contribution.
Dialogue and discussion: Reflections on a Socratic method
Authors: Altorf Hannah Marije
Published: October 2016

This article starts from the observation that Socratic dialogues in the Nelson–Heckmann tradition can create a sense of belonging or community among participants. This observation has led me to the current argument that Socratic dialogue offers an alternative to more prominent forms of conversation, which I have called ‘discussion’ and ‘discourse of uncritical acceptance.’ I explain the difference between these forms of conversation by considering the role of experience in Socratic dialogue and the requirement that participants put themselves in each other’s shoes. My argument is structured according to the different phases in a Socratic dialogue and placed within the literature on this method, as well as Hannah Arendt’s writing on imagination.
Strength of basalt fibers influenced by thermal and chemical treatments
Authors: Overkamp Tim , Mahltig Boris , Kyosev Yordan
Published: October 2016

This paper presents an experimental investigation regarding the influence of the thermal and chemical treatment over the strength of one type industrially used basalt fibers. The fibers are heated at 160℃, 320℃, 480℃, 640℃, or 800℃ using a muffle furnace for 32, 64, 128, or 256 min. In the second series, the fibers are treated with 10% to 30% H2SO4, HCl and NaOH aqueous solutions for 48 h. The strength of the fibers is tested after the different treatments and is found to be decreased even after moderate heating temperatures. The fibers are as well investigated by scanning electron microscopy and energy-dispersive spectroscopy. By energy-dispersive spectroscopic method, the surface composition of the fiber is determined and significant changes in composition are observed even after treatment at 160℃. Obviously the change in surface composition is related to the change in the strength. A possible explanation can be the decomposition of the sizing on the fiber surface.
Territories of Engagement in the Design of Ecohumanist Healthcare Environments
Authors: Peters Terri , Verderber Stephen
Published: October 2016

Background:

Increasingly, architectural and allied designers, engineers, and healthcare facility administrators are being challenged to demonstrate success in adroitly identifying and contextualizing ever-shifting and expanding spheres of knowledge with respect to the role of energy conservation and carbon neutrality in healthcare treatment environments and their immediate exterior environs.

Aim:

This calls for making sense of an unprecedented volume of information on building energy usage and interdigitizing complex and at times contradictory goals with the daily requirements of building occupants. Ecohumanist Design Strategies: In response, a multidimensional framework is put forth with the aim of advancing theory and practice in the realm of designers’, direct caregivers’, and administrators’ engagement with ecohumanist design strategies in the creation of ecohumanist healthcare environments.

Conclusions:

Ten territories for engagement are presented that both individually and collectively express salient themes and streams of inquiry in theory and practice, within an operative framework placing the patient, the patient’s significant others, and the caregiver at the center of the relationship between the built environment and occupant well-being.
Social Media and Political Campaigning
Authors: Jensen Michael J.
Published: October 2016

This paper develops a way for analyzing the structure of campaign communications within Twitter. The structure of communication affordances creates opportunities for a horizontal organization power within Twitter interactions. However, one cannot infer the structure of interactions as they materialize from the formal properties of the technical environment in which the communications occur. Consequently, the paper identifies three categories of empowering communication operations that can occur on Twitter: Campaigns can respond to others, campaigns can retweet others, and campaigns can call for others to become involved in the campaign on their own terms. The paper operationalizes these categories in the context of the 2015 U.K. general election. To determine whether Twitter is used to empower laypersons, the profiles of each account retweeted and replied to were retrieved and analyzed using natural language processing to identify whether an account is from a political figure, member of the media, or some other public figure. In addition, tweets and retweets are compared with respect to the manner key election issues are discussed. The findings indicate that empowering uses of Twitter are fairly marginal, and retweets use almost identical policy language as the original campaign tweets.

Transforming Prior Authorization to Decision Support
Authors: Newcomer Lee N. , Weininger Richard , Carlson Robert W.
Published: October 2016

Purpose:

To evaluate a computer-based prior authorization system that was designed to include and test two new concepts for physician review: (1) the tool would minimize denials by providing real-time decision support with alternative options if the original request was noncompliant, and (2) the tool would collect sufficient information to create a patient registry.

Methods:

A new prior authorization tool incorporating real-time decision support was tested with a large national payer. The tool used the National Comprehensive Cancer Network Clinical Practice Guidelines in Oncology as the content for decision making. Physicians were asked to submit the minimal amount of clinical data necessary to reach a treatment-decision node within the National Comprehensive Cancer Network Guidelines. To minimize denials, all available recommended treatments were displayed for physician consideration and immediate authorization was granted for any compliant selection.

Results:

During a 1-year pilot in a Florida commercial health plan, 4,272 eligible cases were reviewed with only 42 denials. Chemotherapy drug costs for the prior authorization pilot were compared with a similar time period in the previous year for the state of Florida, as well as for the Southeast region and for the nation, which served as controls. The percentage change between the time periods was −9% in Florida, 10% for the national costs, and 11% for the Southeast region costs. The difference between the regional increase and the Florida decrease represented a savings of $5.3 million dollars for the state of Florida in 1 year.

Conclusion:

There is significant opportunity to reduce the costs of therapy while being compliant with nationally accepted guidelines for cancer chemotherapy.
Hemoglobin–oxygen affinity in high-altitude vertebrates: is there evidence for an adaptive trend?
Authors: Storz Jay F.
Published: October 2016

In air-breathing vertebrates at high altitude, fine-tuned adjustments in hemoglobin (Hb)–O2 affinity provide an energetically efficient means of mitigating the effects of arterial hypoxemia. However, it is not always clear whether an increased or decreased Hb–O2 affinity should be expected to improve tissue O2 delivery under different degrees of hypoxia, due to the inherent trade-off between arterial O2 loading and peripheral O2 unloading. Theoretical results indicate that the optimal Hb–O2 affinity varies as a non-linear function of environmental O2 availability, and the threshold elevation at which an increased Hb–O2 affinity becomes advantageous depends on the magnitude of diffusion limitation (the extent to which O2 equilibration at the blood–gas interface is limited by the kinetics of O2 exchange). This body of theory provides a framework for interpreting the possible adaptive significance of evolved changes in Hb–O2 affinity in vertebrates that have colonized high-altitude environments. To evaluate the evidence for an empirical generalization and to test theoretical predictions, I synthesized comparative data in a phylogenetic framework to assess the strength of the relationship between Hb–O2 affinity and native elevation in mammals and birds. Evidence for a general trend in mammals is equivocal, but there is a remarkably strong positive relationship between Hb–O2 affinity and native elevation in birds. Evolved changes in Hb function in high-altitude birds provide one of the most compelling examples of convergent biochemical adaptation in vertebrates.
Current versus future reproduction and longevity: a re-evaluation of predictions and mechanisms
Authors: Zhang Yufeng , Hood Wendy R.
Published: October 2016

Oxidative damage is predicted to be a mediator of trade-offs between current reproduction and future reproduction or survival, but most studies fail to support such predictions. We suggest that two factors underlie the equivocal nature of these findings: (1) investigators typically assume a negative linear relationship between current reproduction and future reproduction or survival, even though this is not consistently shown by empirical studies; and (2) studies often fail to target mechanisms that could link interactions between sequential life-history events. Here, we review common patterns of reproduction, focusing on the relationships between reproductive performance, survival and parity in females. Observations in a range of species show that performance between sequential reproductive events can decline, remain consistent or increase. We describe likely bioenergetic consequences of reproduction that could underlie these changes in fitness, including mechanisms that could be responsible for negative effects being ephemeral, persistent or delayed. Finally, we make recommendations for designing future studies. We encourage investigators to carefully consider additional or alternative measures of bioenergetic function in studies of life-history trade-offs. Such measures include reactive oxygen species production, oxidative repair, mitochondrial biogenesis, cell proliferation, mitochondrial DNA mutation and replication error and, importantly, a measure of the respiratory function to determine whether measured differences in bioenergetic state are associated with a change in the energetic capacity of tissues that could feasibly affect future reproduction or lifespan. More careful consideration of the life-history context and bioenergetic variables will improve our understanding of the mechanisms that underlie the life-history patterns of animals.
The private life of echidnas: using accelerometry and GPS to examine field biomechanics and assess the ecological impact of a widespread, semi-fossorial monotreme

Published: October 2016

The short-beaked echidna (Tachyglossus aculeatus) is a monotreme and therefore provides a unique combination of phylogenetic history, morphological differentiation and ecological specialisation for a mammal. The echidna has a unique appendicular skeleton, a highly specialised myrmecophagous lifestyle and a mode of locomotion that is neither typically mammalian nor reptilian, but has aspects of both lineages. We therefore were interested in the interactions of locomotor biomechanics, ecology and movements for wild, free-living short-beaked echidnas. To assess locomotion in its complex natural environment, we attached both GPS and accelerometer loggers to the back of echidnas in both spring and summer. We found that the locomotor biomechanics of echidnas is unique, with lower stride length and stride frequency than reported for similar-sized mammals. Speed modulation is primarily accomplished through changes in stride frequency, with a mean of 1.39 Hz and a maximum of 2.31 Hz. Daily activity period was linked to ambient air temperature, which restricted daytime activity during the hotter summer months. Echidnas had longer activity periods and longer digging bouts in spring compared with summer. In summer, echidnas had higher walking speeds than in spring, perhaps because of the shorter time suitable for activity. Echidnas spent, on average, 12% of their time digging, which indicates their potential to excavate up to 204 m3 of soil a year. This information highlights the important contribution towards ecosystem health, via bioturbation, of this widespread Australian monotreme.

Published: October 2016

In 2013, Centro Nacional de Control de Energía (CENACE), which is Mexico’s power system operator, updated its short-term hydrothermal coordination planning (STHTCP) tool. CENACE utilized commercial software to solve mixed-integer programming models for the unit commitment and economic dispatch of thermal units, such as gas, coal-fired, and combined-cycle plants. In an earlier paper that we reference, authors of this paper describe the mathematical model for the thermal unit commitment (TUC) problem, which is a sub-problem in the STHTCP process. The new STHTCP tool, which uses a mixed-integer programming-based TUC approach, has enhanced the modeling and solution quality compared to the Lagrangian relaxation-based TUC approach. The new tool has improved CENACE’s operations for managing its existing infrastructure, including power stations and transmission lines, and establishing the marginal prices needed to make energy trades. From the beginning of 2013 to the end of 2014, CENACE saved $2.2 million annually, which it attributes to better management of its thermal units. Over 10 years, it anticipates that these savings will represent more than $20 million in total savings.
Trials based on specific fracture configuration and surgical procedures likely to be more relevant for decision making in the management of fractures of the proximal humerus
Authors: Sabharwal S. , Patel N. K. , Griffiths D. , Athanasiou T. , Gupte C. M. , Reilly P.
Published: October 2016

Objectives

The objective of this study was to perform a meta-analysis of all randomised controlled trials (RCTs) comparing surgical and non-surgical management of fractures of the proximal humerus, and to determine whether further analyses based on complexity of fracture, or the type of surgical intervention, produced disparate findings on patient outcomes.

Methods

A systematic review of the literature was performed identifying all RCTs that compared surgical and non-surgical management of fractures of the proximal humerus. Meta-analysis of clinical outcomes was performed where possible. Subgroup analysis based on the type of fracture, and a sensitivity analysis based on the type of surgical intervention, were also performed.

Results

Seven studies including 528 patients were included. The overall meta-analysis found that there was no difference in clinical outcomes. However, subgroup and sensitivity analyses found improved patient outcomes for more complex fractures managed surgically. Four-part fractures that underwent surgery had improved long-term health utility scores (mean difference, MD 95% CI 0.04 to 0.28; p = 0.007). They were also less likely to result in osteoarthritis, osteonecrosis and non/malunion (OR 7.38, 95% CI 1.97 to 27.60; p = 0.003). Another significant subgroup finding was that secondary surgery was more common for patients that underwent internal fixation compared with conservative management within the studies with predominantly three-part fractures (OR 0.15, 95% CI 0.04 to 0.63; p = 0.009).

Conclusion

This meta-analysis has demonstrated that differences in the type of fracture and surgical treatment result in outcomes that are distinct from those generated from analysis of all types of fracture and surgical treatments grouped together. This has important implications for clinical decision making and should highlight the need for future trials to adopt more specific inclusion criteria. Cite this article: S. Sabharwal, N. K.

For decades, many researchers and teachers in the field of English Language Teaching (ELT) have acknowledged the challenges of bridging the gap between research and practice (Belcher, 2007; Korthagen, 2007). These are challenges for both teachers­ (e.g., technical language used in research) and researchers (e.g., lack of pedagogical implications for teachers). Wilder Escobar, editor of the book Social Research Applied to English Language Teaching in Colombian Contexts: Theory and Methods, attempts to address these challenges and invites authors to offer readers practical applications in ELT.
The festival of moors and christians as pillar of the arts.
Authors: Martínez Pozo Miguel Ángel , Anta Félez José-Luis
Published: October 2016

ABSTRACTThe Festivals of Moors and Christians represents a unique and concrete world that crosses both the history and geography of Spain and its social, political and economic configurations. Historically, they have had a pedagogical sense and, for that reason, they present the complexity of different events, elements, objects and actors that compose it as contrasting elements (assimilation of nationalism and regionalisms or the eternal Hispanic struggle between good and evil), making everything appear normal, exerting a power that few celebrations hold. These chameleonic feasts have adapted to different historical moments and, with the coming of postmodernity, have opened their gates to a colorful game of fantasy where visual and performing arts have become of the utmost importance.

El experimento se realizó en el Laboratorio de Biología de la Facultad de Ciencias Agrarias de la Universidad Nacional de Asunción, el objetivo fue establecer un protocolo de embriogénesis cigótica y enraizamiento de esta especie. Se utilizó un diseño completamente al azar, aplicándose el test Kruskal-Wallis y Mann-Whitney con 5% de probabilidad de error, previa comprobación de supuestos de distribución. Los tratamientos fueron medios MS (Murashige y Skoog) con bencilaminopurina (BAP) en 1, 2 y 4 ppm, medios MS con 2 g/L de carbón activado (CA) y MS simples. Se utilizaron 45 embriones cigóticos cultivados inicialmente en medios MS con 2g/L de CA, expuestos a oscuridad inicial por 20 días; posteriormente subcultivados en los tratamientos. La variable medida fue la longitud radicular, evaluada en dos periodos de 20 días. No existió efectos significativos en los tratamientos con BAP, el CA suprimió la oxidación en explantes; mientras que, los mejores resultados presentaron los tratamientos 1 (MS+1 ppm de BAP) y 4 (MS+CA 2g/L) con 6 y 5 cm de longitud radicular respectivamente, luego de 40 días de incubación.
A Life-Saving Therapy: The Theory-Building Case of "Cora"
Authors: Halvorsen Margrethe Seeger , Benum Kirsten , Haavind Hanne , McLeod John
Published: October 2016

The present paper presents a case study of long-term (121 sessions over three years), integrative therapy with "Cora," a client with a history of severe relational trauma that had led to difficulty in forming close relationships, and a history of hospitalization resulting from a series of suicide attempts. Despite these challenges, Cora reported a highly satisfactory outcome at the end of therapy. Using the format of a theory-building case study (McLeod, 2010; Stiles, 2007), qualitative analysis of session evaluations, session transcripts, and post therapy interviews were used to investigate how both the client and therapist understood the process of therapy and why it had been successful. Data from quantitative process and outcome measures were analyzed to provide contextual information. In spite of repeated challenges and difficult therapeutic situations, Cora and the therapist were able to establish a recurring pattern of interaction that they found relevant and productive and that was characterized by persistence. Other helpful aspects of the therapy process included acting with courage, and the use of symbolic representations of their accomplishments. The results contribute to our understanding of the process of therapy with clients who have been exposed to severe relational trauma. The discussion includes reflection on methodological issues associated with mixed-methods case study research in psychotherapy.
Conceptualizing the Complexity of Change in Psychotherapy: The Case of "Cora"
Authors: Halvorsen Margrethe Seeger , McLeod John , Benum Kirsten , Haavind Hanne
Published: October 2016

In this article we respond to the commentaries by Altman and Miller (2016), Bohart (2016), and Timulak and Keogh (2016) on our case of “Cora,” which involved over 121 psychotherapy sessions with a client with a history of severe relational trauma that had led to difficulty in forming close relationships, as well as a series of suicide attempts (Halvorsen, Benum, Haavind, & McLeod, 2016). The commentaries differ in their view of the value of Cora’s case, interpretations of the material, and methodological preferences. Together the commentaries illustrate the complexity of change in psychotherapy, how we need multifaceted approaches to understand change, and the challenges in writing up a case in this context. We call for further dialogue within the psychotherapy research community around the nature and implications of methodological choices arising from the conduct of case study research in this field.
Tourism Sector on the Zagreb Stock Exchange (ZSE): What is the Value of Croatian Tourism?
Authors: Penda Ivor Altaras
Published: October 2016

In this paper the author investigates and analyzes the historical and current data on the shares of the tourism sector on the Zagreb Stock Exchange (ZSE), and on that basis he is trying to estimate the value of entire Croatian tourism. He also argues that the lack of transparency of the domestic capital market, and in particular its inefficiency, is directly reflected on the tourism sector as its significant component. Tourism represents about 15% of the total Croatian economy, with clear indications that it is one of the few segments in which Croatia has certain success, and has significant progress in this part of the national economy. Thereby tourism sector deserves special attention on the securities market, which has one of the fundamental tasks to find funds on the market for financing development projects.
An Analysis of the Global Code of Ethics for Tourism in the Context of Corporate Social Responsibility
Authors: Buzar Stipe
Published: October 2016

Welfare: The Negative Societal Effects
Authors: Knight Victoria , Simpson David , Block Walter
Published: October 2016

The welfare system was instituted, presumably, to decrease poverty, increase the wealth and well-being of the poor. Paradoxically, it has had just about the opposite effect. How did this boomerang in public policy occur? It is simple. Welfare payments helped break up the family, disproportionately in the black community. But a non-intact family is one of the most effective causal agents in impoverishment. Hence, a program that throws massive amounts of money at poor people reduces their economic wellbeing, does not increase it.

Tourism – An Outsider’s View
Authors: Vukonić Boris
Published: October 2016

When nearly fifty years ago I wrote my first article on tourism, I could have written and talked about “an outsider’s view”. Everything that followed was “an insider’s view”. However, since I am no longer active, in the literal meaning of the word, in tourism, I can again rightfully claim that this article will offer “an outsider’s view”. Nevertheless, today this view is significantly different from the one I held during my early engagement with Croatian tourism, due to the diverse experience I gained during my longstanding career. As a result, this title should be taken as an effort to provide the article with a more attractive heading than article titles found in professional publications or as a tendency to give it a special meaning.

This paper attempts to provide a summarized explanation of the position of modern Croatian tourism today, to make relevant the tourism results in Croatia in 2015 and to offer author’s commentary on preparations for the tourism season 2016.
Russian Roulette; Rejoinder to Robins
Authors: Block Walter E.
Published: October 2016

This paper is an attempt to understand and elaborate upon libertarian punishment theory. It is completely non-controversial, even amongst non-libertarians, that the criminal must be forced to return his ill-gotten gains to the victim. At least among libertarians, it is agreed upon, in addition, that the punishment for the criminal must be proportionate to his crime. This, typically, implies that what he did to the victim should be done to him. For example, if A steals a car from B, A must be compelled to return that automobile to B, and, then, to give B a vehicle owned by A. But what about the fact that A scared B when he committed his dastardly crime? Should punishment theory take that into account too, and, if so, how? That is the subject of the present paper.
The Problem of Carbon Dioxide Emissions from Closed Coal Mine Shafts – The Overview and the Case Study
Authors: Wrona Paweł , Sułkowski Józef , Różański Zenon , Pach Grzegorz
Published: October 2016

Greenhouse gas emissions are a common problem noticed in every mining area just after mine closures. However, there could be a significant local gas hazard for people with continuous (but variable) emission of these gases into the atmosphere.

In the Upper Silesia area, there are 24 shafts left for water pumping purposes and gases can flow through them hydraulically. One of them – Gliwice II shaft – was selected for inspection. Carbon dioxide emission with no methane was detected here. Changes in emission and concentration of carbon dioxide around the shaft was the aim of research carried out.

It was stated that a selected shaft can create two kinds of gas problems. The first relates to CO2 emission into the atmosphere. Possible emission of that gas during one minute was estimated at 5,11 kg CO2/min. The second problem refers to the local hazard at the surface. The emission was detected within a radius of 8m from the emission point at the level 1m above the ground.

These kinds of matters should be subject to regular gas monitoring and reporting procedures.
Goniolimon dalmaticum Rchb. f. and G. tataricum (L.) Boiss. (Plumbaginaceae) in the Croatian Flora and their Distribution in the Balkan Peninsula
Authors: Buzurović Uroš , Bogdanović Sandro , Niketić Marjan , Tomović Gordana
Published: October 2016

Goniolimon tataricum (L.) Boiss. is recognized as a new species for the Croatian flora. Besides G. dalmaticum Rchb. f., G. tataricum represents the second species of this genus in Croatia. To confirm the identity of G. tataricum as a new species, morphometric study and multivariate statistical analysis were performed on the data from four Croatian populations of G. dalmaticum and G. tataricum. Based on results of morphometric analysis, an identification key for these two species is provided. Data about distribution in the Balkan Peninsula, habitat and ecology of the newly-recorded species are also presented. Typification of G. dalmaticum was performed for the first time.

Published: October 2016

In the present study, the micromorphological structure of achene, pappus and style using scanning electron microscope (SEM), stomatal characteristics, anatomy of stem and achene together with chromosome number and nuclear DNA content of the Turkish endemicCrepis macropusBoiss. & Heldr. are provided in order to expand knowledge of its taxonomy. The SEM studies in this species show that dense spiny cells are found on the achene surface, the pappus bristle has 3–5 spikes and the style possesses slender papillae. The stem structure is composed of epidermis, collenchyma, parenchymatous cortex and pith. The species has anomocytic stomata in both the upper and the lower surface of the leaves. The pericarp of the achene is mainly composed of several layers of sclerenchymatous cells. In this species, the chromosome number is 2n = 2x = 8, karyotype consists of two submetacentric and six subtelocentric chromosomes and nuclear DNA content (2Cvalue) is 12.96 pg. These data are presented here for the first time and their taxonomic values are discussed.
Intracluster Homogeneity Selection Problem in a Business Survey
Authors: Žmuk Berislav
Published: October 2016

Background: In the cluster sampling approach many parameters have influence on lowering the survey costs and one of the most important is the intracluster homogeneity.

Objectives: The goal of the paper is to find the most optimal value of intracluster homogeneity in case when two or more questions or variables have a key role in the research.

Methods/Approach: Five key variables have been selected from a business survey conducted in Croatia and results for the two-stage cluster sampling design approach were simulated. The calculated intracluster homogeneity values were compared among all the five observed questions and survey costs and precision levels were inspected.

Results: In the new cluster sampling design, for the fixed precision level, the lowest survey costs would be achieved by using the intracluster homogeneity value which is the closest to the average intracluster homogeneity value among all the key questions. Similar results were obtained when survey costs were held fixed.

Conclusions: If there is more than one key question in the survey, then the best solution would be to use an average intracluster homogeneity value. However, one should notice that in that case minimum survey costs would not be reached, but the precision levels would increase at all key questions.
Polypropylene – zinc oxide nanorod hybrid material for applications in separation processes

Published: October 2016

Hybrid filter material was obtained via modification of polypropylene (PP) nonwoven with nanosize zinc oxide particles of a high aspect ratio. Modification was conducted as a three-step process, a variant of hydrothermal method used for synthesis of nano-ZnO, adopted for coating three dimensional polymeric nonwoven filters. The process consisted of plasma treatment of nonwoven to increase its wettability, deposition of ZnO nanoparticles and low temperature hydrothermal growth of ZnO rods. The modified nonwovens were investigated by a high resolution scanning electron microscopy (HR-SEM). It has been found that the obtained hybrid filters offer a higher filtration efficiency, in particular for so called most penetrating particle sizes.
