Export Destination, Product Quality and Wages in a Middle‐Income Country - The Case of South Africa

A robust finding in the firm‐level literature is that exporting firms pay higher wages. Using South African data this paper investigates the relationship between export destination and wages at a worker level. South Africa, a middle‐income country, has two distinct main export markets - a regional market where per capita incomes are lower than at home, and an international market with higher per capita incomes. Our estimates show that workers in firms that export to the region earn less than those that produce for the domestic market. Those in firms that export outside the region earn more than either domestic producers or region‐only exporters. Much of this difference in wages can be explained by the premium the different types of exporters pay for skills. These results support previous studies which suggest that export destination is related to product quality which in turn is related to worker quality and therefore wages.
Managerial Innovation: Conceptions, Processes and Antecedents

The expansive research on innovation in organizations has primarily followed a technological imperative, postulating that organizations organize their innovation efforts through research and development (R&D) activities. Theories of innovation are thus shaped mosdy from the studies of technology-based innovations in the manufacturing sector, yet are applied in all contexts. This article advocates research on managerial innovations - new approaches to devise strategy and structure of tasks and units, modify the organization's management processes and administrative systems, motivate and reward organizational members, and enable organizational adaptation and change. We examine the conceptual development, generation and adoption processes, antecedents, and influences of managerial innovation on organizational conduct. By increasing an understanding of managerial innovation, this article aims to complement existing theories of innovation derived from the studies of technological innovations and thus help extend and advance theory and research on innovation process and outcome in organizations.
Chinese Tourists' Motivations and Satisfaction of Visiting North Korea

This article reports results from a survey of 23 semi-structured interviews with Chinese visitors to North Korea. The interviews examined the motives for and subsequent assessments of their tour of North Korea. In addition to expected assessments such as perceptions of North Korea as a unique destination, the satisfaction derived from sightseeing, watching the Arirang performance and meeting to a limited extent North Korean people, there were also adverse comments about inadequate Korean programmes, overly flexible travel schedules that could change at a moment's notice, high prices and poor standards of food quality. One contribution that the article makes to the wider literature is not only is it a description of an under-researched tourist destination, but also an examination of the nature of cross-country comparisons and the role of nostalgia that emerged in these interviews.

Effect of Formal Contracts, Relational Norms and Trust on Performance of Joint Research and Development Projects

This paper examines the effect of governance mechanisms – formal contracts, relational norms and trust – on the performance of exploration and exploitation joint research and development (R&D) projects. While the authors acknowledge the need for a twofold approach, transactional and relational, to understand the interfirm exchange governance, the joint action of formal contracts and relational governance has been caught between the complementary or substitutive forces involved in interorganizational relationships. Using survey data on joint exploration and exploitation R&D projects developed by the European biotechnology companies, the synergies of both mechanisms and their effects in improving project performance are investigated. The analysis suggests that contracts and relational norms and trust act as complementary mechanisms, but while contracts are more effective in exploitation projects, relational norms and trust are more powerful in improving the performance of exploration projects.
Negative, not positive symptoms predict the early therapeutic alliance in cognitive behavioral therapy for psychosis

Abstract Objective: The strength of therapeutic alliance is consistently associated with therapy outcome. The aim of this study was to identify relevant predictors for early therapeutic alliance in cognitive behavioral therapy for psychosis. Method: Fifty-six patients with schizophrenia spectrum disorders were included in the analysis. Possible predictors (positive and negative symptoms, depression, insight, social functioning, theory of mind, and medication adherence) were assessed at baseline. Alliance was assessed after each therapy session. Results: Lower negative symptoms significantly predicted higher patient and therapist rated alliance. Conclusions: The findings indicate that negative symptoms might be a barrier to the development of therapeutic alliance. Assumed underlying processes and practical implications are discussed.
The Redistributive Effects of Agricultural Policy on Scottish Farm Incomes

This paper focuses on the measurement of the redistributive effects of agricultural policy, proposing measures to characterise and quantify these effects that are based on the change in absolute value of the Gini coefficient. An illustrative study shows that the distribution of support in Scotland in 1999/2000 was regressive with respect to pre-support farm incomes. Nevertheless, the provision of support would have had an equalising effect on farm incomes but for the resulting changes in the ranking of farms within the income distribution. Reranking not only makes ‘coupled’ support policies ineffective but also inefficient as redistributive instruments.
Does the Progressivity of Income Taxes Matter for Human Capital and Growth

We develop a model with heterogeneity in skills to study the effect of tax progressivity on economic growth. The probability of becoming skilled depends positively on expenses on teacher time. We consider growth resulting from an externality due to skilled workers and from their employment in research and development. We show changes in the progressivity of taxes can have growth effects even when changes in flat rate taxes have none. The response is stronger with externality-driven growth. Progressive taxation, often suggested to reduce inequality, can increase the long-run skill premium and decrease the upward mobility of the poor. Copyright 2006 Blackwell Publishing Inc.
The Effects of FTC Advertising Regulation

THIS study inquires into the effects of the FTC's regulation of false and misleading advertising. Skepticism about the effectiveness of this regulation is widespread. For example, a Congressional committee has described the regulation as "impotent. "' A team of lawyers under the aegis of Ralph Nader has echoed that sentiment.2 The best that an American Bar Association panel could say was that "occasional successes" could not outweigh the "recurrent flaws of FTC enforcement. "3 A noted legal scholar, who has cast doubt on the only "success" cited,4 wonders if a system of regulation without penalties can be effective but argues that this is probably for the best since there is no substantial problem worth regulating anyway.5 The authors of an industrial organization textbook think that there is a problem but damn by faint praise an enforcement mecha-
RE‐EXAMINING THE DIFFERENTIAL FAMILIAL LIABILITY OF AGORAPHOBIA AND PANIC DISORDER

Controversy surrounds the question of whether agoraphobia (AG) exists as an independent diagnostic entity apart from panic. In favor of this position, AG without panic disorder (PD) in parents was found being unrelated to offsprings’ risk for AG or PD, albeit it may enhance the familial transmission of PD (Nocon et al., Depress Anxiety 2008;25:422–434). However, a recent behavioral genetic analysis (Mosing et al., Depress Anxiety 2009;26:1004–1011) found an increased risk for both PD and AG in siblings of those with AG without PD, casting doubt on whether AG exists independently of PD. Convincing evidence for either position notably requires considering also other anxiety disorders to establish the position of AG relative to the panic/anxiety spectrum.
Pathological gambling amongst Parkinson's disease and ALS patients in an online community (PatientsLikeMe.com)

Pathological gambling (PG) has been identified in Parkinson's disease (PD), but such gambling behaviors may also occur in amyotrophic lateral sclerosis (ALS). We sought to estimate the prevalence of PG amongst members of a web‐based community, PatientsLikeMe.com. A survey was constructed, consisting of demographic information, the South Oaks Gambling Screen (SOGS), the K‐6 measure of distress, and items related to motivation for gambling. Data were obtained from 236 ALS patients and 208 PD patients. Of the PD patients, 13% were classified as problem gamblers compared with 3% of ALS patients (χ2 = 14.005, P ≤ 0.001). PD patients reported thoughts about gambling to be more distressing, harder to resist and more outside their control than ALS patients. Thus, the higher prevalence of compulsive behavior in PD may relate to damaged reward pathways or medication rather than to the effects of living with a chronic progressive neurological disorder per se. © 2009 Movement Disorder Society
Work‐based competences and careers prospects: a study of Spanish employees

Purpose – This paper aims to identify the work‐based competences associated with better career prospects in the Spanish labour market.Design/methodology/approach – The relationship between employee‐based competencies and employment prospects is investigated through the lens of the competence‐based approach. The partial least squares (PLS) methodology is applied on a sample of over 5,000 Spanish employees.Findings – The analysis establishes that skill, motivation, participation in decision‐making and the performance of non‐routine and complex tasks are associated with more favourable career prospects. Finally, it has also been found that human capital dimensions valued by firms vary with occupation, as clear differences have been observed between white‐ and blue‐collar occupations. In particular, social skills and motivation appear to be more relevant for blue‐collar workers than for white‐collar workers.Originality/value – For the first time, this paper analyses employees' career prospects using work‐base.
Accounting Conservatism and Performance Covenants: A Signaling Approach

This study examines the relation between performance covenants in private debt contracting and conservative accounting under adverse selection. We find that under severe adverse selection (i.e., high information asymmetry), accounting conservatism and performance covenants act as complements to signal that the borrower is unlikely to appropriate wealth from the lender. No such relation obtains in a low information asymmetry regime. We further show that in the high information asymmetry regime, borrowers with high levels of conservatism and tight performance covenants generally enjoy lower interest rate spreads than borrowers with low levels of conservatism and loose performance covenants. Consistent with our signaling theory, in the high information asymmetry regime, borrowers with high levels of conservatism and tight performance covenants are less likely to make abnormal payouts to shareholders. Our empirical results are robust to alternative measures of conservatism and covenant restrictiveness.
A mechanical model of actin stress fiber formation and substrate elasticity sensing in adherent cells

Tissue cells sense and respond to the stiffness of the surface on which they adhere. Precisely how cells sense surface stiffness remains an open question, though various biochemical pathways are critical for a proper stiffness response. Here, based on a simple mechanochemical model of biological friction, we propose a model for cell mechanosensation as opposed to previous more biochemically based models. Our model of adhesion complexes predicts that these cell-surface interactions provide a viscous drag that increases with the elastic modulus of the surface. The force-velocity relation of myosin II implies that myosin generates greater force when the adhesion complexes slide slowly. Then, using a simple cytoskeleton model, we show that an external force applied to the cytoskeleton causes actin filaments to aggregate and orient parallel to the direction of force application. The greater the external force, the faster this aggregation occurs. As the steady-state probability of forming these bundles reflects a balance between the time scale of bundle formation and destruction (because of actin turnover), more bundles are formed when the cytoskeleton time-scale is small (i.e., on stiff surfaces), in agreement with experiment. As these large bundles of actin, called stress fibers, appear preferentially on stiff surfaces, our mechanical model provides a mechanism for stress fiber formation and stiffness sensing in cells adhered to a compliant surface.
MHC‐dependent survival in a wild population: evidence for hidden genetic benefits gained through extra‐pair fertilizations

Females should prefer to be fertilized by males that increase the genetic quality of their offspring. In vertebrates, genes of the major histocompatibility complex (MHC) play a key role in the acquired immune response and have been shown to affect mating preferences. They are therefore important candidates for the link between mate choice and indirect genetic benefits. Higher MHC diversity may be advantageous because this allows a wider range of pathogens to be detected and combated. Furthermore, individuals harbouring rare MHC alleles might better resist pathogen variants that have evolved to evade common MHC alleles. In the Seychelles warbler, females paired with low MHC‐diversity males elevate the MHC diversity of their offspring to levels comparable to the population mean by gaining extra‐pair fertilizations. Here, we investigate whether increased MHC diversity results in higher life expectancy and whether there are any additional benefits of extra‐pair fertilizations. Our 10‐year study found a positive association between MHC diversity and juvenile survival, but no additional survival advantage of extra‐pair fertilizations. In addition, offspring with a specific allele (Ase‐ua4) had a fivefold longer life expectancy than offspring without this allele. Consequently, the interacting effects of sexual selection and pathogen‐mediated viability selection appear to be important for maintaining MHC variation in the Seychelles warbler. Our study supports the prediction that MHC‐dependent extra‐pair fertilizations result in genetic benefits for offspring in natural populations. However, such genetic benefits might be hidden and not necessarily apparent in the widely used fitness comparison of extra‐ and within‐pair offspring.
A Novel Marker for Vertebrate Embryonic Heart, the EH-myomesin Isoform*

Myomesin is a structural component of the M-band that is expressed in all types of striated muscle. Its primary function may be the maintenance of the thick filament lattice and its anchoring to the elastic filament system composed of titin. Different myomesin isoforms have been described in chicken and mice, but no particular function has been assigned to them. Here we investigate the spatio-temporal expression pattern of myomesin isoforms by means of reverse transcriptase-polymerase chain reaction and isoform-specific antibodies. We find that two alternative splicing events give rise to four myomesin isoforms in chicken contrary to only one splicing event with two possible isoforms in mice. A splicing event at the C terminus results in two splice variants termed H-myomesin and S-myomesin, which represent the major myomesin species in heart and skeletal muscle of avian species, respectively. In contrast, in mammalian heart and skeletal muscle only S-myomesin is expressed. In embryonic heart of birds and mammals, alternative splicing in the central part of the molecule gives rise to the isoform that we termed EH-myomesin. It represents the major myomesin isoform at early embryonic stages of heart but is rapidly down-regulated around birth. Thus, the strict developmental regulation of the EH-myomesin makes it an ideally suited marker for embryonic heart.
Constructively managing conflicts in organizations

Researchers have used various concepts to understand the conditions and dynamics by which conflict can be managed constructively. This review proposes that the variety of terms obscures consistent findings that open-minded discussions in which protagonists freely express their own views, listen and understand opposing ones, and then integrate them promote constructive conflict. Studies from several traditions also suggest that mutual benefit relationships are critical antecedents for open-minded discussion. This integration of research findings identifies the skills and relationships that can help managers and employees deal with their increasingly complex conflicts. Research is needed to deepen our understanding of the dynamics of open-minded discussion and the conditions that promote it as well as when open-mindedness is inappropriate. Training studies can test and show how the model of open-minded discussion supported by mutual benefit relationships can be applied in cross-cultural and other challengin.
Use of PCR-Restriction Fragment Length Polymorphism Analysis To Identify the Main New World Leishmania Species and Analyze Their Taxonomic Properties and Polymorphism by Application of the Assay to Clinical Samples

ABSTRACT At least 13 characterized Leishmania species are known to infect humans in South America. Five of these parasites are transmitted in the sylvatic ecotopes of the whole French Guianan territory and responsible for cutaneous leishmaniasis. For the diagnosis of cutaneous leishmaniasis, restriction fragment length polymorphism (RFLP) analyses have shown promising results. Thus, the end of the small subunit and internal transcribed spacer 1 of the rRNA genes were sequenced and targeted by PCR-RFLP analysis in the 10 main New World (NW) Leishmania species from the two subgenera. Then, the procedure was tested on 40 samples from patients with cutaneous leishmaniasis, and its results were compared with those of conventional methods. (i) The results of this simple genus-specific method were in agreement with those of previous isoenzyme analyses. (ii) This method distinguished the most medically relevant Leishmania species with only one enzyme (RsaI). (iii) This method could be performed directly on human biopsy specimens (sensitivity of 85.7%). Performing NW Leishmania species typing rapidly and easily in the field constitutes a very valuable improvement for detection of Leishmania spp. Revealing great diversity with several enzymes, this method could also be useful for taxonomic, ecological, and epidemiological studies in space and time.
Improving Hospital Survival and Reducing Brain Dysfunction at Seven California Community Hospitals: Implementing PAD Guidelines Via the ABCDEF Bundle in 6,064 Patients*

Objectives: To track compliance by an interprofessional team with the Awakening and Breathing Coordination, Choice of drugs, Delirium monitoring and management, Early mobility, and Family engagement (ABCDEF) bundle in implementing the Pain, Agitation, and Delirium guidelines. The aim was to study the association between ABCDEF bundle compliance and outcomes including hospital survival and delirium-free and coma-free days in community hospitals. Design: A prospective cohort quality improvement initiative involving ICU patients. Setting: Seven community hospitals within California’s Sutter Health System. Patients: Ventilated and nonventilated general medical and surgical ICU patients enrolled between January 1, 2014, and December 31, 2014. Measurements and Main Results: Total and partial bundle compliance were measured daily. Random effects regression was used to determine the association between ABCDEF bundle compliance accounting for total compliance (all or none) or for partial compliance (“dose” or number of bundle elements used) and outcomes of hospital survival and delirium-free and coma-free days, after adjusting for age, severity of illness, and presence of mechanical ventilation. Of 6,064 patients, a total of 586 (9.7%) died before hospital discharge. For every 10% increase in total bundle compliance, patients had a 7% higher odds of hospital survival (odds ratio, 1.07; 95% CI, 1.04–1.11; p < 0.001). Likewise, for every 10% increase in partial bundle compliance, patients had a 15% higher hospital survival (odds ratio, 1.15; 95% CI, 1.09–1.22; p < 0.001). These results were even more striking (12% and 23% higher odds of survival per 10% increase in bundle compliance, respectively, p < 0.001) in a sensitivity analysis removing ICU patients identified as receiving palliative care. Patients experienced more days alive and free of delirium and coma with both total bundle compliance (incident rate ratio, 1.02; 95% CI, 1.01–1.04; p = 0.004) and partial bundle compliance (incident rate ratio, 1.15; 95% CI, 1.09–1.22; p < 0.001). Conclusions: The evidence-based ABCDEF bundle was successfully implemented in seven community hospital ICUs using an interprofessional team model to operationalize the Pain, Agitation, and Delirium guidelines. Higher bundle compliance was independently associated with improved survival and more days free of delirium and coma after adjusting for age, severity of illness, and presence of mechanical ventilation.
Testing different forms of efficiency for Dhaka Stock Exchange

The Efficient-Market Hypothesis (EMH) asserts that efficient markets are informationally efficient or all information (market, public or private) should reflect on stock prices. No one could earn excess profit using any kind of information in efficient market. There are three forms of efficiency in markets: strong, semi-strong and weak. We tested EMH for Dhaka Stock Exchange (DSE) for the period 2003â€“2005. We used the excess return market model to test the semi-strong form efficiency of DSE. Two forecasting techniques, Autoregressive Integrated Moving Average (ARIMA) and neural network, are used to test the weak form efficiency of DSE. We get excess return for many stocks listed in DSE, demonstrating that DSE is not an efficient market in semi-strong form. Besides, the DSE market index is not random and the trend could be captured by ARIMA and neural network techniques. Therefore, the DSE is also not an efficient market in weak form.
