The retrospective diagnosis of concussion is often missed by clinicians. We present a brief scale for retrospective assessment of the immediate concussion symptoms (ICS) to facilitate the diagnosis of patients without visible head injury or full loss of consciousness. We administered the scale to 90 survivors of car accidents (mean age 42.0, SD=13.6; 33 males, 57 females) at 2 to 33 months after their accident. Our scale consists of 6 items and these were endorsed by the following % of our respondents: feeling dazed (64.4% of our 90 respondents), stunned (73.3%), confused (70.0%), disoriented (62.2%), dizzy (57.8%), and loss of consciousness (22.2%). The statistical properties of the scale are satisfactory (Cronbach alpha = 0.74). The scale correlates with post-accident insomnia (r=0.28), depression (r=0.29), and also with Rivermead measure of the chronic post-concussion syndrome (r=0.34). The ICS scale could be used as a starting point in longitudinal research with brain imaging procedures to evaluate the stages of recovery from the initial concussion. Attached are the English, Spanish, French, German, Italian, Russian, and Czech versions of our scale.

A patient in her 20s was referred to us for psychological assessment due to her depression and suicide attempts. She mentioned being anorgasmic except when diapered and emphasized her erotic preference for diapers. Her childhood included maternal deprivation in an impecunious family headed by an irritable physically disabled father on social assistance. Given the maternal deprivation in childhood, her erotic fixation on diapers parallels the emotional attachment to diapers observed by Harlow in mother deprived infant monkeys. Etiological hypotheses should also include the paradigm of avoidance learning from theories of behavior therapy. Our patient does not wish to change her sexual preference: in such cases, fetishism is not considered as an illness by DSM5. However, she needs to be treated for pathological levels of depression with suicidal ideation and low self-esteem.

It seems that some aspects of employees' experience can lead to their “losing faith in the system of paid employment”. This disillusion can be studied and measured through the theoretical construct of a psychological contract breach experienced by the employee. This exploratory article thus examines whether the conditions of paid employment could lead to a new dimension of psychological contract breaches: a breach with paid employment itself that could drive to self-employment.

The authors use a structural equation modeling on a sample of 403 people who have declared their intention to leave paid employment for self-employment.

The study's results show that working conditions affect psychological contract breaches in various dimensions. The authors propose a dimension of psychological contract breaches linked to paid employment, which can lead to the choice to leave paid employment and become self-employed. The authors also confirm the importance of working conditions as antecedents of psychological contract breaches.

The main limitations of this exploratory research are the use of unvalidated scales and a small sample size, with a population that could be better defined. As Murgia et al. (2020) point out, it is not yet clear at the moment whether this category is a special group, equivalent to traditionally distinguished groups of working people. The study's assumptions and these limitations lead us to propose the following avenues for future research.

For managers and the development of management, the possible relationship between working conditions and psychological contract breaches seems to be very important. In fact, a whole range of best management practices could be developed if this relationship is confirmed. Improving working conditions could thus be a way to repair psychological contracts.

This research field is still quite underdeveloped in comparison to its importance to organizations because the increase in self-employment challenges traditional models and assumptions in human resources management.

This study aims to expand the theoretical frameworks of psychological contracts and breaches. It thus responds to recent calls for research on psychological contracts (Bankins et al., 2020); Moreover, this research suggests, in line with the work of Aubert and de Gaulejac (2018), that there are relationships between poor working conditions and psychological contract breaches. To the authors' knowledge, this approach is missing from international research into psychological contracts, which focuses only on job characteristics and individual determinants (personality traits, etc.).

The purpose of this paper is to evaluate an experiment to improve residents’ opinions of the police in Portland, Oregon. Officers conducted community engagement patrols (CEPs) in 60 high-crime areas. The CEPs prioritized non-investigative contacts with community members to build trust and promote positive police–community interactions in designated high-crime locations. It is hypothesized that community members living in/near intervention sites would report greater exposure to officers, more positive interactions and feel more positively about police than residents in control areas.

In total, 90 crime hot spots were identified using crime reports and calls for service. Locations were randomized into three groups: 2 CEPs/day (n=30), 4 CEPs/day (n=30), and control (i.e. no supplemental patrols, n=30). Officers were dispatched to treatment locations via the computer-aided dispatch system for 90 consecutive days, resulting in 16,200 scheduled CEPs. Surveys were mailed to 11,760 households immediately after the intervention ended and 1,537 were returned (13.1 percent).

Residents from intervention areas reported a higher number of positive police contacts, whereas contacts that residents perceived as negative did not differ between the three conditions. Community attitudes, including perceived police legitimacy, were generally unaffected by CEP dosage.

This paper documents the outcomes of a large-scale field experiment seeking to improve public attitudes toward police using directed CEPs in crime hot spots. Whereas the intervention succeeded in providing more opportunities for positive contact with police, attitude change may necessitate longer-term strategies.

A better understanding of the determinants of demand through accurate estimates of the elasticity of import demand can help policymakers and exporters improve their market access and competitiveness. This study analyzed the EU's demand for imported potato from major suppliers between 1994 and 2018, with the aim to evaluate the competitiveness of Egyptian potato.

This study adopted an import-differentiated framework to investigate demand relationships among the major potato suppliers to the EU's. To evaluate the competitiveness of Egyptian potato on the EU market, expenditure and price demand elasticities for various suppliers were calculated and compared.

The empirical results indicated that as income allocation of fresh potatoes increases, the investigated EU markets import more potatoes from other suppliers compared to imports from Egypt. The results show that EU importers may switch to potato imports from other suppliers as the import price of Egyptian potatoes increases, which enter the EU markets before domestically produced potatoes are harvested.

Due to data unavailability, the present study relied on yearly data on quantities and prices of EU potato imports. A higher frequency of observations should allow for considering seasonal effects, and thereby providing a more transparent picture of market dynamics and demand behavior of EU countries with respect to potato import from various sources of origin.

The study used a system-wide and source differentiated approach to analyze import demand. In particular, the empirical approach allowed for comparing different demand models (AIDS, Rotterdam, NBR and CBS) to filter out the superior and most suitable model for that data because the suitability and performance of a demand model depends rather on data than on universal criteria.

The history of economics has often been described as the “history of economic thought.” In this essay, I explore an alternative perspective that builds on the French tradition of historical epistemology and treats economics as a social practice. I argue that a practice-based view provides a more philosophically robust conception of historiography and a richer field of investigation for historians of economics.

Brussels Free University Information and Documentation Science Department is implementing a documentary computer system, to be used as an in‐house cost‐free access, educational tool for its students. The online bibliographic search subsystem, called SERIDU, is based on a subset of the Euronet standard command language, which is being implemented by several DIANE hosts. A comparison is made of Euronet and of SERIDU commands, as well as of the data elements of Unisist Reference Manual and of the storage subsystems of the Department. A description is given of SERIDU commands, and is illustrated by a short sample session. The software is briefly described, as well as its present shortcomings and the future developments of the system, which might interest other library schools.

The purpose of this study is to describe the systematic process in developing an interpersonal communication material for the prevention and control of noncommunicable diseases (NCDs) in the City of Manila, Philippines.

The systematic process in the development of an interpersonal communication material is presented. The seven steps in the process included mapping of available health communication materials, needs identification, development of the material, pretesting, finalization, printing/production and orientation on the use of the material.

The process followed an iterative, multistakeholder approach in order to ensure that all important insights are obtained and that the final material is contextualized, easily communicated and culturally appropriate. It is important to consider context and culture on top of the methodology in order to ensure development of appropriate interpersonal communication material. It is also important that the experience of the primary health-care workers on the use of the interpersonal communication material is properly documented for future reference, through both quantitative and qualitative evaluations.

The seven-step systematic process utilized can be used as a model in developing health communication materials in the field of health promotion and education.

This article describes financial professionals' perceptions of their clients' financial behaviors and the explanatory factors underlying these behaviors.

In this qualitative research, the authors seek to understand financial professionals' experiences in relation to how their clients manage their own finances. The authors conduct and analyze 26 semi-structured interviews with financial professionals from several industries within the financial sector in Canada.

The professionals in this study noted that despite their clients' financial knowledge, several other factors can explain these individuals' financial behaviors. They include psychological factors (such as financial bias, the need for instant gratification, and the lack of awareness regarding the long-term effects of certain types of financial behaviors), financial habits (such as lifestyle, financial planning and lack of discipline) and the financial system's flexibility with respect to debt financing and repayment. These perceptions are categorized according to whether they are related to debt financing or repayment, savings or investments.

By using a qualitative methodology that relies on the perceptions of financial professionals, this study aims to better understand the financial behaviors of individuals and households, and these behaviors' underlying factors. This study's findings could be useful to various stakeholders interested, in one way or another, in financial literacy, such as organizations aiming to strengthen and promote financial literacy, educators, researchers, regulatory bodies of financial institutions and financial advisers.
