Some Evidence on the Demand for Money

I ALTHOUGH the demand function for money balances has been subject to a great deal of empirical investigation in the last few years, much remains to be done on establishing its exact nature. In this paper, I present the results of some recent work on this matter. As is usually the case, it is much easier to describe the statistical results of the study than to give them any firm economic interpretation. They are as follows. Permanent income is a better explanatory variable for the demand for money, no matter whether money is defined to include or exclude time deposits, than is either measured income or nonhuman wealth. Time deposits alone, however, are best explained by non-human wealth. Despite this latter fact, the stability of the demand function for money is improved by including time deposits in the definition of money. These results seem to throw light on three crucial issues in monetary theory. They suggest that inasmuch as wealth
Knowledge Sharing Among Accounting Academics in an Electronic Network of Practice

SYNOPSIS: Using a multi-method approach, we explore accounting academics’ knowledge-sharing practices in an Electronic Network of Practice (ENOP)—the Accounting Education using Computers and Multimedia (AECM) email list. Established in 1996, the AECM email list serves the global accounting academic community. A review of postings to AECM for the period January–June 2006 indicates that members use this network to post questions, replies, and opinions covering a variety of topics, but focusing on financial accounting practice and education. Sixty-nine AECM members constituting 9.2 percent of the AECM membership base responded to a survey that measured their self-perceptions about altruism, reciprocation, reputation, commitment, and participation in AECM. The results suggest that altruism is a significant predictor of posting frequency, but neither reputation nor commitment significantly relate to posting frequency. These findings imply that designers and administrators of the recently launched AAA Commons p.
On the Size Distribution of Business Firms

This paper proposes a new theory of the size distributions of business firms. It postulates an underlying distribution of persons by managerial "talent" and then studies the division of persons into managers and employees and the allocation of productive factors across managers. The implications of the theory for secular changes in average firm size are developed and tested on U.S. time series.
Long-term drug administration in the adult zebrafish using oral gavage for cancer preclinical studies

ABSTRACT Zebrafish are a major model for chemical genetics, and most studies use embryos when investigating small molecules that cause interesting phenotypes or that can rescue disease models. Limited studies have dosed adults with small molecules by means of water-borne exposure or injection techniques. Challenges in the form of drug delivery-related trauma and anesthesia-related toxicity have excluded the adult zebrafish from long-term drug efficacy studies. Here, we introduce a novel anesthetic combination of MS-222 and isoflurane to an oral gavage technique for a non-toxic, non-invasive and long-term drug administration platform. As a proof of principle, we established drug efficacy of the FDA-approved BRAFV600E inhibitor, Vemurafenib, in adult zebrafish harboring BRAFV600E melanoma tumors. In the model, adult casper zebrafish intraperitoneally transplanted with a zebrafish melanoma cell line (ZMEL1) and exposed to daily sub-lethal dosing at 100 mg/kg of Vemurafenib for 2 weeks via oral gavage resulted in an average 65% decrease in tumor burden and a 15% mortality rate. In contrast, Vemurafenib-resistant ZMEL1 cell lines, generated in culture from low-dose drug exposure for 4 months, did not respond to the oral gavage treatment regimen. Similarly, this drug treatment regimen can be applied for treatment of primary melanoma tumors in the zebrafish. Taken together, we developed an effective long-term drug treatment system that will allow the adult zebrafish to be used to identify more effective anti-melanoma combination therapies and opens up possibilities for treating adult models of other diseases. Summary: We have developed the first long-term drug delivery system in the adult zebrafish using oral gavage, and offer a foundation for future preclinical studies of cancer therapeutics in adult zebrafish.
The Effect of Requiring Private Employers to Extend Health Benefit Eligibility to Same‐Sex Partners of Employees: Evidence from California

Health disparities related to sexual orientation are well documented and may be due to unequal access to a partner's employer-sponsored insurance (ESI). We provide the literature's first evaluation of legislation enacted by California in 2005 that required private employers within the state to treat employees in committed same-sex relationships in the same way as employees in different-sex marriages with respect to ESI. Our analysis uses data on sexual orientation, partnership, and health insurance from the 2001 to 2007 California Health Interview Surveys (CHIS). Prior to the reform, partnered gay men and lesbians were significantly less likely to have ESI in someone else's name than partnered heterosexuals. Pooling data from 2001 to 2007, we find that the reform had no effects on differences in insurance outcomes between gay and straight men. We find some evidence that the reform increased partnership, reduced full-time employment, and increased health insurance coverage among lesbians relative to heterosexual women. The increases in insurance coverage for lesbians are consistent with a role for expanded dependent ESI, suggesting that such policies may reduce sexual orientation-based insurance disparities among women.
Polanyi in Brussels: Supranational Institutions and the Transnational Embedding of Markets

Abstract Many have argued that the success of European integration is predicated on reinforcing market structures and some have gone further to state that the creation of a transnational market results in a decoupling of markets from their national political and social frameworks, thus threatening to unravel historical social bargains. Drawing on the work of Karl Polanyi and John Ruggie and using their insights regarding the social embedding of markets, we dissent from this view by examining how the European Court of Justice (ECJ) has handled a key sector of the emerging European market—labor mobility. We argue that rather than disembedding markets, decisions of the ECJ—just as Polanyi and Ruggie would have predicted—activate new social and political arrangements. We find evidence for the development of a new legal and political structure, largely inspired by the Court but also imbricated in European Union legislation, at the regional level.
Multifocal occurrence of gastric carcinoma in patients with a family history of gastric carcinoma

Smoking and alcoholic beverage drinking habits as well as a family history of cancer are well known risk factors for the multifocal occurrence of squamous cell carcinoma of the esophagus and the head and neck region. However, the role of these risk factors in multiple gastric carcinoma remains to be clarified. The purpose of this study was to examine the risk factors for multiple gastric carcinoma.
Incumbent Decisions about Succession Transitions in Family Firms: A Conceptual Model

In the family business literature, succession research has focused on the family member as they enter the leadership role or on the different issues that affect the succession process. Although researchers have acknowledged that succession in family businesses is “punctuated” by decision making events, less attention has been given to understanding how incumbents make decisions about ownership and management transitions. In an effort to continue to understand the succession process it is important to understand how incumbents make decisions about the type of transitions they intend to engage in ( i.e. , intra-family succession, out of family succession, or no succession). Building on the theory of planned behavior and the socioemotional wealth framework (SEW), this manuscript presents a conceptual framework to understand the factors that influence succession transitions and the role that contextual factors can play in this decision-making process. We present theory driven propositions and discuss the implications for understanding and evaluation of the succession process.
Exploring Personal Branding on YouTube

Developing a personal brand in the social media world is now a rapidly growing trend. Existing literature examines how companies can utilize social media to build their brands. However, the phenomenon of branding online has rarely been examined from a personal perspective, despite its growing importance. This qualitative study seeks to address this peculiar absence and tries to understand how and what personal branding can be formed within the social media consumption (e.g., YouTube). The results reveal areas of potential development for personal branding and consumer-personal brand relationships as a result of consumer empowerment on YouTube. The key managerial implication shows that the dynamics of the business-to-branding and consumer-brand relationships have been transformed from a company perspective and a one-dimensional occurrence to a personal perspective and a bidirectional social bond on YouTube.
Patient opinion of the doctor-patient relationship in a public hospital in Qatar.

OBJECTIVE To analyze the factors associated with the level of satisfaction of outpatients in their relationship with their doctor at the largest public hospital in Qatar. METHODS This study was a cross-sectional survey of attitudes. Researchers surveyed 626 outpatients at Hamad General Hospital in Doha, Qatar from September 2009 to January 2010 using a novel questionnaire assessing satisfaction with patients' interaction(s) with their doctor (spent time with patient, took case seriously, maintained confidentiality, and the overall quality of visit). RESULTS Mean responses on 4 Likert scale items (one to 5) were as follows: "spent enough time with patient" = 4.39; "doctor took case seriously" = 4.57; "satisfaction with doctor-patient confidentiality" = 4.71; "overall quality of visit" = 4.46. Age, gender, citizenship, level of education, and number of visits did not significantly impact the level of satisfaction. For 73.1% of patients, the physician's qualification was the most important factor in choosing a doctor. Of those surveyed, 40.7% of men and 28.1% of women preferred to see a doctor of their own gender. A positive correlation between perceived communication and satisfaction with the doctor-patient encounter was established. CONCLUSION This study found that patients in the Out-Patient Department at Hamad Hospital were highly satisfied with their relationships with their doctors, and physician qualification was the most significant factor in choosing a doctor. A significant number of males and females preferred a physician of their own gender. Communication difficulty correlated with lower satisfaction.
The Trustworthiness of Online Channels for Experience- and Goal-Directed Search Tasks

Travelers have used the Internet as an information channel for years and more recently also started to produce content themselves. With an abundance of information channels competing for customers’ attention, researchers and practitioners need to better understand which online channels are trustworthy and consulted for travel-related factual information or for reports on experiences. Thus, this article compares the trustworthiness of three different online channels (personal, marketing, and editorial). The results of the experiment indicate that user-generated content appears to be highly trustworthy, showing high levels of integrity; however, it is not always regarded as the most informative. Editorial content providers, such as tourist boards, are considered to be the most able information provider. The results confirm that depending on the type of online channel, different dimensions of trustworthiness become effective as drivers of overall trust.
Ship-berth link performance evaluation: simulation and analytical approaches

In this paper we consider the performance evaluation of ship-berth link in port. The efficiency of operations and processes on the ship-berth link has been analysed through the basic operating parameters such as berth utilization, average number of ships in waiting line, average time that a ship spends in waiting line, average service time of a ship, average total time that a ship spends in port, average quay crane (QC) productivity and average number of QCs per ship. All the main performances of the ship-berth link are given. This is one of the problems faced by planners and terminal operators in ports. In this paper, we propose two models based on simulation and queuing theory, respectively, in order to determine the performance evaluation of ship-berth link in port. Numerical results and computational experiments are reported to evaluate the efficiency of the models for Pusan East Container Terminal (PECT).
A test of three interventions to promote people's communication of their consent for organ donation

People's decision to join an organ donor registry and have a discussion with family about their organ donation preference increases the likelihood that their family will consent to donation of their organs. This study explores the effectiveness of three interventions compared to a control condition to increase individual consent (registering and discussing donation wishes) for organ donation. Australian residents who had not previously communicated their consent (N = 177) were randomly allocated to complete an online survey representing either an extended theory of planned behaviour motivational intervention (strengthening intention via attitudes, subjective norms, control, moral norms and identity), a volitional intervention using constructs from the health action process approach (strengthening the translation of intentions into action using action plans and coping plans), a combined motivational and volitional intervention, or a control condition. Registering, but not discussing, intentions increased in the motivational compared to non-motivational conditions. For joining the organ donor registry, the combination of strengthening intentions (motivational) as well as forming specific action (when, where, how, and with whom for discussing) and coping (listing potential obstacles and how these may be overcome) plans (volitional) resulted in significantly higher rates of self-reported behaviour. There was no evidence for this effect on discussion.
Beyond the Many Faces of Price: An Integration of Pricing Strategies

The author reviews the field of pricing strategy and constructs a unifying taxonomy of the many strategies described in the literature. The taxonomy is based on the simple proposition that all the strategies have a common denominator—shared economies among buyer segments, across firms, or among products. The author presents the strategies in comparable terms, emphasizing the principles underlying each and demonstrating the relationship among strategies, the circumstances in which each can be used, and the legal and policy implications of each.
An empirical analysis of productivity growth in retail services: evidence from Spain

Purpose – This paper seeks to estimate total productivity change in retailing firms and to decompose it into efficiency change and technical change (TC) (i.e. the consequence of innovation and adoption of new technologies). Design/methodology/approach – This paper adopts the efficient approach using the Malmquist productivity index for a sample of 96 supermarket chains operating in Spain between 1995 and 2003.Findings – The results show a slight increase in average annual productivity among the firms analysed.Research limitations/implications – The generalisation of the conclusions of the study to the whole sector should be made with caution, because only one of the players in the distribution channel has been analysed.Practical implications – It is shown that the main component of productivity change is TC. This result means that new ICTs have the capacity to alter the productive structures of retail firms, favouring their productivity.Originality/value – The contribution of this paper is based on the app.
Cell surface markers CD44 and CD166 localized specific populations of salivary acinar cells.

OBJECTIVE Experimental approaches tested to date for functional restoration of salivary glands (SGs) are tissue engineering, gene transfer, and cell therapy. To further develop these therapies, identifying specific cell surface markers for the isolation of salivary acinar cells is needed. To test a panel of cell surface markers [used in the isolation of mesenchymal stem cells, (MSCs)] for the localization of salivary acinar cells. MATERIALS Human submandibular and parotid glands were immunostained with a panel of MSC markers and co-localized with salivary acinar cell differentiation markers [α-amylase, Na-K-2Cl cotransporter-1, aquaporin-5 (AQP5)]. Additional cell markers were also used, such as α-smooth muscle actin (to identify myoepithelial cells), cytokeratin-5 (basal ductal cells), and c-Kit (progenitor cells). RESULTS CD44 identified serous acini, while CD166 identified mucous acini. Cytokeratin-5 identified basal duct cells and 50% of myoepithelial cells. None of the remaining cell surface markers (Stro-1, CD90, CD106, CD105, CD146, CD19, CD45, and c-Kit) were expressed in any human salivary cell. CONCLUSIONS CD44 and CD166 localized human salivary serous and mucous acinar cells, respectively. These two cell surface markers will be useful in the isolation of specific populations of salivary acinar cells.
Semi-automated and automated glioma grading using dynamic susceptibility-weighted contrast-enhanced perfusion MRI relative cerebral blood volume measurements.

OBJECTIVE Despite the established role of MRI in the diagnosis of brain tumours, histopathological assessment remains the clinically used technique, especially for the glioma group. Relative cerebral blood volume (rCBV) is a dynamic susceptibility-weighted contrast-enhanced perfusion MRI parameter that has been shown to correlate to tumour grade, but assessment requires a specialist and is time consuming. We developed analysis software to determine glioma gradings from perfusion rCBV scans in a manner that is quick, easy and does not require a specialist operator. METHODS MRI perfusion data from 47 patients with different histopathological grades of glioma were analysed with custom-designed software. Semi-automated analysis was performed with a specialist and non-specialist operator separately determining the maximum rCBV value corresponding to the tumour. Automated histogram analysis was performed by calculating the mean, standard deviation, median, mode, skewness and kurtosis of rCBV values. All values were compared with the histopathologically assessed tumour grade. RESULTS A strong correlation between specialist and non-specialist observer measurements was found. Significantly different values were obtained between tumour grades using both semi-automated and automated techniques, consistent with previous results. The raw (unnormalised) data single-pixel maximum rCBV semi-automated analysis value had the strongest correlation with glioma grade. Standard deviation of the raw data had the strongest correlation of the automated analysis. CONCLUSION Semi-automated calculation of raw maximum rCBV value was the best indicator of tumour grade and does not require a specialist operator. ADVANCES IN KNOWLEDGE Both semi-automated and automated MRI perfusion techniques provide viable non-invasive alternatives to biopsy for glioma tumour grading.
Arabic-speaking religious leaders’ perceptions of the causes of mental illness and the use of medication for treatment

Objectives: The Arabic-speaking clergy is highly revered and considered the first point of contact for people who suffer from mental illness within their community. The current study aimed to explore the beliefs of Arabic-speaking religious leaders regarding the causes of mental illness and the use of medication for their treatment. Method: Participants consisted of 170 Arabic-speaking clerics of Muslim (n = 85) and Christian (n = 85) denominations residing in Sydney, Australia. A questionnaire was administered during face-to-face interviews and included items regarding the causes of mental illness and beliefs about whether psychiatric medications were viewed as helpful or harmful. Results: Most of the Arabic-speaking clerics viewed drug and alcohol addiction and psychosocial factors as the most important causes of mental illness. Biological causes such as a chemical imbalance in the brain were less frequently endorsed. Although medications were viewed by most religious clerics as helpful in the treatment of mental illness, there were also concerns about the potential harms of medications, particularly among Muslim clerics. Muslim clerics also endorsed the religious causes for mental illness, such as spiritual poverty, as being more important more so than did Christian clerics. Conclusions: The beliefs of Arabic-speaking religious leaders influence how they respond to people with mental illness and may determine whether they refer people to professional mental health services or not. Understanding their perspectives allows opportunities to share information to facilitate collaborative work in the care of Arabic-speaking people with mental illness. Arabic-speaking religious leaders need to be better educated about the mechanisms of action and benefits of medication in the treatment of mental illness.
Sinorhizobium meliloti Mutants Deficient in Phosphatidylserine Decarboxylase Accumulate Phosphatidylserine and Are Strongly Affected during Symbiosis with Alfalfa

ABSTRACT Sinorhizobium meliloti contains phosphatidylglycerol, cardiolipin, phosphatidylcholine, and phosphatidylethanolamine (PE) as major membrane lipids. PE is formed in two steps. In the first step, phosphatidylserine synthase (Pss) condenses serine with CDP-diglyceride to form phosphatidylserine (PS), and in the second step, PS is decarboxylated by phosphatidylserine decarboxylase (Psd) to form PE. In this study we identified the sinorhizobial psd gene coding for Psd. A sinorhizobial mutant deficient in psd is unable to form PE but accumulates the anionic phospholipid PS. Properties of PE-deficient mutants lacking either Pss or Psd were compared with those of the S. meliloti wild type. Whereas both PE-deficient mutants grew in a wild-type-like manner on many complex media, they were unable to grow on minimal medium containing high phosphate concentrations. Surprisingly, the psd-deficient mutant could grow on minimal medium containing low concentrations of inorganic phosphate, while the pss-deficient mutant could not. Addition of choline to the minimal medium rescued growth of the pss-deficient mutant, CS111, to some extent but inhibited growth of the psd-deficient mutant, MAV01. When the two distinct PE-deficient mutants were analyzed for their ability to form a nitrogen-fixing root nodule symbiosis with their alfalfa host plant, they behaved strikingly differently. The Pss-deficient mutant, CS111, initiated nodule formation at about the same time point as the wild type but did form about 30% fewer nodules than the wild type. In contrast, the PS-accumulating mutant, MAV01, initiated nodule formation much later than the wild type and formed 90% fewer nodules than the wild type. The few nodules formed by MAV01 seemed to be almost devoid of bacteria and were unable to fix nitrogen. Leaves of alfalfa plants inoculated with the mutant MAV01 were yellowish, indicating that the plants were starved for nitrogen. Therefore, changes in lipid composition, including the accumulation of bacterial PS, prevent the establishment of a nitrogen-fixing root nodule symbiosis.
