Comparing Econometric Methods to Empirically Evaluate Job-Search Assistance

We test whether different empirical methods give different results when evaluating job-search assistance programs. Budgetary problems at the Dutch unemployment insurance (UI) administration in March 2010, caused a sharp drop in the availability of these programs. Using administrative data provided by the UI administration, we evaluate the effect of the program using (1) the policy discontinuity as a quasi-experiment, (2) conventional matching methods, and (3) the timing-of-events model. All three methods use the same data to consider the same program in the same setting, and also yield similar results. The program reduces job finding during the first six months after enrollment. At longer durations, the quasi-experimental estimates are not significantly different from zero, while the non-experimental methods show a small negative effect.
Does the effect of enjoyment outweigh that of anxiety in foreign language performance

Interest in the effect of positive and negative emotions in foreign language acquisition has soared recently because of the positive psychology movement (Dewaele & MacIntyre, 2014, 2016; MacIntyre, Gregersen & Mercer, 2016). No work so far has been carried out on the differential effect of positive and negative emotions on foreign language performance. The current study investigates the effect of foreign language enjoyment (FLE) and foreign language classroom anxiety (FLCA) on foreign language performance in a group of 189 foreign language pupils in two London secondary schools and a group of 152 Saudi English as a foreign language learners and users of English in Saudi Arabia. Correlation analyses showed that the positive effect of FLE on performance was stronger than the negative effect of FLCA. In other words, FLE seems to matter slightly more than FLCA in foreign language (FL) performance. Qualitative material collected from the Saudi participants shed light on the causes of FLCA and FLE and how these shaped participants’ decisions to pursue or abandon the study of the FL.
Evaluation of Techniques for Categorizing Group Membership of White-Tailed Deer

Abstract We studied sexual segregation, particularly patterns of group membership for white-tailed deer (Odocoileus virginianus), in Lincoln County, Minnesota, USA, to evaluate current techniques used to categorize animals when studying sexual segregation. We categorized group membership according to Hirth (1977) and grouped individuals using our solitary categorization method. Our solitary method was most sensitive to changes in behavior and physiology exhibited by reproductively active females and their association with other deer during sexual segregation.
Consumer Expectations Regarding Sustainable Food: Insights from Developed and Emerging Markets

This study advances marketers’ knowledge about consumer expectations regarding sustainable food in both industrialized (Germany, United States, Switzerland) and emerging economies (Brazil, China, India). Data was obtained through an online consumer survey of 1,179 respondents. Findings show that consumer expectations regarding sustainable food consist of five factors: ethic attributes, naturalness, health-related aspects, terroir, and innovation. International agri-business marketers can use the outcomes of this study to design well-tailored communication strategies promoting sustainable food. Scholars can build upon the resulting multi-country sustainability scale to reach a less western-biased understanding of consumer expectations of sustainable food in emerging economies.
Hydrolyzed hemp seed proteins as bioactive peptides

Hemp seed cake, a by-product of cold oil processing, represents a food waste material of high nutritional value. Therefore, in this research, it was used as starting raw material for bioactive peptides production. Alkali extraction followed by isoelectric precipitation was employed for hemp protein isolation.Subsequently, the influence of different enzymes (alcalase and pancreatin), as well as the degree of hydrolysis on the kinetics of different molecular weights peptides production and their antioxidant potential was investigated. The DPPH• scavenging activity of hemp protein hydrolysates and hemp protein isolate and their reducing power was determined.The obtained results showed that the strongest antioxidant activity exhibited peptides characterized by the highest degree of hydrolysis. In general, it was concluded that the properties of the obtained hydrolysates were dependent on the type and specificity of the employed protease, as well as the hydrolysistime.
Vorticity and Stress Tensor

The assumptions of the Navier-Stokes equations are reconsidered. Vorticity is one of the three basic isotropic motions of a fluid element about a point. Taking into consideration the isotropic and symmetric nature of the associated tensor, it was assumed that vorticity could not contribute to the viscous stresses and hence was omitted from subsequent derivations of the Navier-Stokes equations. Deviating from this classical approach, the effect of vorticity is included in the derivation of the stress tensor.The equation hence derived contains additional terms involving vortex viscosity. Analogous to Maxwell stress tensor in electromagnetic fields, another stress tensor is defined in a vorticity field. By treating vortices as physical structures, it is possible to define pressure and the shearing stress that deform the volume element.
Asset Pricing with Heterogeneous Inattention

Can households’ limited attention to the stock market quantitatively account for the bulk of asset prices? I address this question introducing an observation cost in a production economy with heterogeneous agents, incomplete markets and idiosyncratic risk. In this environment inattention changes endogenously over time and across agents. I calibrate the observation cost to match the observed duration of inattention of the median agent in the data. The model generates limited participation in the stock market, a weak correlation between consumption growth and stock returns, and countercyclical dynamics for both the stock returns volatility and the excess return. It also generates forms of predictability in stock returns and consumption growth. Nonetheless, the level of the equity premium is still low, around 1%. Finally, I nd that inattention aects asset prices if borrowing constraints are tight enough.
RF Immunity of Digital Integrated Circuits: Measurements, Modeling and Validation

This paper demonstrates that the Mπlog technique, already proposed in the literature for the generation of accurate and efficient IC macromodels, can be extended to the prediction of device immunity effects. The proposed models account for both the functional and the out-of-band behaviour of devices. The IC models are generated from port device responses only and can be implemented in any commercial tool based on SPICE or VHDL-AMS solvers. The approach is demonstrated on a real test board by injecting a RF noise disturbance into a digital IC: a systematic study comparing actual measurements and simulation predictions is carried out.

Influence of Ethephon Treatments on Quality Changes in Dashehari Mango (Mangifera indica L.) during Ripening

Influence of Ethephon Treatments on Quality Changes in Dashehari Mango (Mangifera indica L.) during Ripening Mango fruits require ripening treatment after harvest to hasten ripening and develop ideal eating quality. Present investigations were carried out to elucidate the potential of ethephon as postharvest dip treatment for enhancement of ripening and quality characteristics of ‘Dashehari’ mango fruits. Freshly harvested fruits were immersed in aqueous solutions of ethephon at 0, 200, 400, 600 or 800 µLL-1 and then placed at ambient temperature for ripening studies. Evaluation of physico-chemical parameters was made at 0 (before treatment), 48, 72, 96, 120 and 144 hrs of ripening. Pulp colour was expressed as L*, a*, b*, h0 and C* values. Results indicated that fruit firmness declined linearly to the dose of ethephon applied and fruit texture became edible after 72 hrs in ethephon 600 or 800 µLL-1treatments. Total soluble solids increased with ripening of fruits and maximum values were recorded at the end of ripening period. There was consistent decrease in juice acid content of fruits with ethephon applications. Highest dose of ethephon (800µLL-1) induced ripening in fruits after 72 hrs of treatment but showed detrimental effect on sensory quality afterwards. However, fruits given 600 µLL-1 ethephon dip ripened after 72 hrs after treatments and these fruit maintained excellent quality attributes up to 144 hrs. Ethephon applications exhibited enhancement in colour attributes of fruit pulp in terms of improved redness or yellowness and chroma. The results indicated that dipping mango fruits in 600 µLL-1 ethephon developed the superior ripening quality at ambient temperature.
Factors Affecting Marital Adjustment among Parents of Autistic Children and Gender Effects

We aimed to systematically review studies that examine factors affecting marital adjustment among parents of children with disabilities, especially the autistic children. Besides, we emphasized the effects of gender on marital adjustments among the parents. There were at least 21 articles reviewed. The related journal articles on factor affecting marital adjustments were downloaded with cut off limit from 1992 to 2012. The articles were then analyzed and organized according to the definitions of marital adjustments and various factor affecting marital adjustments. We found there was no conclusive evidence regarding the factors affecting the marital among parents of autistics children. There was conclusive evidence from the reviewed literature regarding gender effect, yet the number of article supporting it was small. Mothers of autistics children were more affected in the marital adjustments as compared to fathers. Finally, with conclusion we then suggest for future interventional study.

Antioxidant, anticancer, and apoptosis-inducing effects of Piper extracts in HeLa cells

Objective: Cervical cancer is the second most common cancer as well as one of leading cause of cancer-related death for women worldwide. In regards to that issue, focus of this paper will be on popularly used Piperaceae members including Piper betle L, Piper cf fragile Benth, Piper umbellatum L, Piper aduncum L, Piper pellucidum L. This research was conducted to elucidate the antioxidant, anticancer and apoptosis inducing activities of Piperaceae extracts on cervical cancer cells, namely HeLa cell line. Methods: The anticancer activity was determined by inhibiting the proliferation of cells. Apoptosis inducing was determined by inhibiting proliferation cells and by SubG1 flow cytometry. The antioxidant activity is determined by using superoxide dismutase value and 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity. Results: The highest anticancer activity at 24 h incubation was found for P.pellucidum extract (IC50: 2.85 µg/ml); The anticancer activity at 48 h incubation was more than at 24 h for all extracts. The highest apoptotic activity was found for P.betle (12.5 µg/ml) at both 24 and 48 h incubatio. The highest antioxidant activity was also represented by P.betle extract. Conclusions: All Piperaceae extracts have high anticancer activity; longer incubation increase anticancer activity. P.betle extract has the highest antioxidant property.
Biodiversity in Chestnut Woodlots: Management Regimen vs Woodlot Size

This paper analyzes the effect of woodlot size and land-use intensity on the species richness of vascular plants, birds, beetles, and ants in Castanea sativa (chestnut) woodlots of the northwestern Iberian Peninsula included in the category “9260 Castanea sativa woodland”, “Annex I, DC 92/43/European Community”. The results show that the surface area of the woodlot did not affect the richness of vascular plants and ants but did affect birds and beetles. The level of abandonment of the woodlot affected only the richness of vascular plants, while the use level had no significant impact on species richness of any of the groups. The degree of maturity of the woodlot, estimated by the tree-trunk circumference, determined only the richness of plants but not that of different groups of animals. In conclusion: 1) Plants and animals responded differently to woodlot size, abandonment, and the degree of maturity of the woodlots; 2) Traditional agricultural practices do not negatively affect the biodiversity of the chestnut woodlots of the northwestern Iberian Peninsula or favor plant diversity; and 3) A traditional use of these woodlots may continue to play an important role in maintaining the diversity of plant species in the area.
Creating programs for Africa's urban youth: the challenge of marginalization (Special issue: Vulnerable, excluded, invisible & ignored: the margins of education for all)

Urban youth constitute the vanguard of Africa’s twinned demographic transformations. Sub-Saharan Africa’s youth population growth rate is the highest of any world region (North Africa’s rate is also high). In addition, Africa’s urban growth rate is the world’s highest. Taken together, the need to provide adequate, effective support for urban youth is critical to fostering Africa’s development – and its political, social and economic stability. This article is designed to help address this need in two ways. First, it focuses attention on those comprising the overwhelming majority of this population, urban youth who are poor and marginalized. Second, drawing largely on the author’s extensive professional experience with African urban youth, the article reviews the major challenges this population faces; considers the programming context for Africa’s urban youth; reviews six principles for developing programs for them; provides field-based insights on improving the assessment, monitoring and evaluation of urban youth programming; and suggest ways to enhance the inclusion of female youth in programs. The article concludes with a consideration of the particular challenge of marginalization in meeting the needs of Africa’s huge urban youth population, and a call to respond to this challenge with youth-centered policy reforms and investments. We are living in the age of youth. There are more young people in today’s world than ever before in human history. This is the case in terms of the proportion of the overall population (Barker 2005, p.11) as well as sheer numbers, which are staggering. One and a half billion of the world’s population are ages 12-24, 1.3 billion of which reside in developing countries. (World Bank 2006, p.4) Almost half of the world’s population is under age twentyfive. (Barker 2005, p.11) While North Africa’s youth population growth rate is significant, Sub-Saharan Africa’s rate is the highest of any world region (the youth population there has quadrupled since 1950) (World Bank 2006, p.33). Africa’s urban growth rate is also the world’s highest (United Nations 2004, p.7), and both of these rates are estimated to remain ahead of all other world regions into the foreseeable future. (World Bank 2006; United Nations 2004) Urban youth constitute the vanguard of Africa’s twinned transformations because youth are the unquestioned vanguard of Africa’s gathering urbanization that features the migration of male youth (Hope 1998, p.352) but includes increasing numbers of female youth.

Managing uncertainties : it ’ s all about Critical Infrastructure Protection ( CIP )

A good and scientific analysis starts with a closer look at the conceptualisation at hand. The definition of CIP is not easy because of its wide range. This paper examines infrastructures that are critical and need protection. Each word entails a specific connotation and is characterized by several components. First, we have to examine the notion ‘infrastructures’, which are generally defined as organizational structures that are necessary for the operation of a society or enterprise or the facilities and services that are essential for an economy to function (Lewis, 2006). The assets are divided into sectors (Lewis et al in Flammini, 2012, p. 4). According to the United States’ National Infrastructure Protection Plan of 2006, infrastructures and key resources can be divided into eighteen sectors. Second, we have to define the notion of ‘critical’, which is problematic because if we take a look at the assets, sectors, organisations and key resources we can ascertain that numerous infrastructures are critical. In order to better understand this concept we have to reflect on the reliability of these infrastructures on the functioning of society. Taking a look at the existing literature, we can highlight that critical infrastructures are mostly defined as those assets, systems or functions that can seriously impact national-level public health, the economy, public safety, governance, national security and public confidence (Lewis et al in Flammini, 2012, p. 4). Critical infrastructures are ‘vital and its incapacity or destruction would have a debilitating impact on our defense and national security. It is a network of independent, often privately owned, systems that function collaboratively and synergistically to produce and distribute a continuous flow of essential goods and services’ (Lewis, 2006, p. 3). Therefore, critical
Effects of dietary lysine level on the content and fatty acid composition of intramuscular fat in late-stage finishing pigs

Abstract: This study was conducted to investigate how dietary lysine level affects the intramuscular fat (IMF) content and fatty acid (FA) composition in late-stage finishing pigs. Nine crossbred barrows [94.4 ± 6.7 kg body weight (BW)] were randomly allotted to three treatment groups (n = 3). Three corn- and soybean-meal-based diets were formulated to meet the National Research Council (2012) requirements for various nutrients except for lysine, whose concentrations were 0.43%, 0.71%, and 0.98% (as-fed basis) for Diets 1 (lysine-deficient), 2 (lysine-adequate), and 3 (lysine-excess), respectively. After 5 wk of ad libitum access to diets, pigs were harvested and longissimus dorsi samples were collected. The IMF content and FA composition of the samples were analyzed by gas chromatography. Results showed that the IMF content of the muscle was increased linearly (P < 0.05) with decreasing dietary lysine level from 0.98% to 0.43%. Dietary lysine level altered the composition of FA, especially the unsaturated FA, in the muscle. Particularly, the percentages of C18:1 n-9 and total monounsaturated FA were higher, whereas the percentages of C18:2 n-6 and total polyunsaturated FA were lower, in the muscle of the pigs fed Diet 1. Collectively, dietary lysine deficiency increased the proportion of monounsaturated FA and decreased the proportion of polyunsaturated FA, which may benefit pork palatability.
Effectiveness of Communication on Students Discipline in Secondary Schools in Kenya.

The influence of communication on student discipline in secondary schools is an issue of continued debate in Kenya. This study was necessitated by the growing concern by education stakeholders in Kenya over the rising reports of student indiscipline in secondary schools. The study utilized qualitative approach with questionnaires, interviews and documentation as instruments of collecting data. Purposive sampling was used to identify Naivasha district as the location of the study. Stratified and simple random sampling was used to identify 8 secondary schools and 200 respondents from these schools. 20 students and 4 teachers in each sampled school were given the self administered questionnaires while all the 8 head teachers were interviewed. The data collected was analyzed descriptively. The findings of this study shows that the level of discipline in secondary schools in Kenya is very low, schools administration rarely discussed implementation of rules and regulations to students hence there are poor channels of communication. Ineffective communication results in conflict, chaos, misunderstanding and lack of confidence in school administration. Factors such as individual communication skills promoted effective communication whereas barriers to interpersonal communication hindered effective communication. This study recommends that the school administration should initiate dialogue when dealing with students to discuss discipline matters, rules and regulations. Regular meetings and morning assemblies should be used as main channels of communication. Schools should avoid ineffective channels of communication which result in conflict, chaos, misunderstanding and lack of confidence in school administration. Guidance and counselling were seen to be effective ways of communication to overcome barriers of communication.
The Effect of Cooperative Learning “ Jigsaw I ” Technique on Student Success in Social Studies Course

The present study investigates the effects of Jigsaw I, one of the techniques in cooperative learning, on student success in social studies course and in the study pre-test post-test control group design, one of the experimental designs, has been used. As a data collection instrument, an achievement test that included “My Far Away Friends” unit was developed and applied as pre-test and post-test. While this unit was taught by means of cooperative learning by the researchers to the experiment group, it was taught using traditional method by the class teacher to the control group. In order to evaluate the data SPSS programme was used. As a result, it was determined that there was a significant difference between the pre-test and post-test points of the control and experiment groups. In addition, the success level of the two groups of students showed a significant difference between pre and post implementation. In other words, it was found significant that being the member of these groups, in which different methods were applied, and repetitive measurement had a common effect on the success in social studies course. Therefore, it is thought that cooperative learning is much more effective than traditional method.
